- 摘要：ObjectiveTo explore the intervention mechanism of Xiangsha Liujunzi Tang in rats with functional dyspepsia （FD） based on the Ras homolog gene family member A （RhoA）/Rho-associated coiled-coil containing protein kinase 2 （ROCK2）/Myosin phosphatase target Subunit 1 （MYPT1） pathway.MethodSixty male SD suckling rats in SPF grades were randomly divided into blank group （n=10） and model group （n=50）. The comprehensive modeling method （gavage administration of iodoacetamide+exhaustion of swimming+disturbance of hunger and satiety） was used to replicate the rat model of FD. After successful replication of the model， the rats in the model group were randomly divided into model group， mosapride group， and high， middle， and low-dose Xiangsha Liujunzi Tang groups， with 10 rats in each group. Rats in the blank group and model group were given 10 mL kg-1·d-1 normal saline， those in the mosapride group were given 1.35 mg·kg-1·d-1 mosapride， and those in the high， middle， and low-dose Xiangsha Liujunzi Tang groups were given 12， 6， and 3 g·kg-1·d-1 Xiangsha Liujunzi Tang， respectively. The intervention lasted 14 days. The general living conditions of rats were observed before and after modeling and administration， and the 3-hour food intake and body mass of rats were measured. After intervention， the intestinal propulsion rate of rats was measured， and the pathological changes in the gastric tissue were observed by hematoxylin-eosin （HE） staining. The content of choline acetyl transferase （ChAT） and vasoactive intestinal peptide （VIP） in the medulla oblongata and gastric tissue homogenate was determined by enzyme-linked immunosorbent assay （ELISA）， the distribution of adenosine triphosphate （ATP） enzyme in gastric antrum smooth muscle was observed by frozen section staining， and the protein expression levels of RhoA， ROCK2， and phosphorylated-myosin phosphatase target subunit 1 （p-MYPT1） in the gastric tissue were detected by Western blot.ResultCompared with the blank group， the model group had withered hair， lazy movement， slow action， poor general living condition， lower 3-hour food intake， body mass， and lower intestinal propulsion rate （P<0.05）， whereas no obvious abnormality in gastric histopathology. In the model group， the content of ChAT in the medulla oblongata and gastric tissue decreased， the content of VIP in gastric tissue increased， the distribution of ATP enzyme in gastric antrum smooth muscle decreased significantly， and the protein expression levels of RhoA， ROCK2， and p-MYPT1 in the gastric tissue decreased significantly （P<0.05）. As compared with the model group， the general living condition of rats in each intervention group was significantly improved， and the 3-hour food intake， body mass， and intestinal propulsion rate were significantly increased （P<0.05）. There was no significant difference in gastric pathology in the intervention groups. The content of ChAT in the medulla oblongata and gastric tissue increased significantly， the content of VIP in the gastric tissue decreased， the distribution of ATP enzyme in gastric antrum smooth muscle increased significantly， and the protein expression levels of RhoA， ROCK2， and p-MYPT1 in the gastric tissue increased significantly （P<0.05）. The intervention effect of Xiangsha Liujunzi Tang group on the above indexes was dose-dependent.ConclusionXiangsha Liujunzi Tang can effectively improve the general living condition and gastric motility of rats with FD， and its specific mechanism may be related to the activation of the RhoA/ROCK2/MYPT1 pathway in the gastric tissue to regulate smooth muscle relaxation and contraction and promote gastric motility.关键词：Xiangsha Liujunzi Tang;spleen and stomach deficiency type;Ras homolog gene family member A （RhoA）;Rho associated coiled-coil containing protein kinase 2 （ROCK2）;phosphorylated-myosin phosphatase target subunit 1 （p-MYPT1）

The m/m mice were included in the blank group. T2DM was induce d in the 50 db/db mice. The model mice were randomized into the model group， metformin group （0.2 g·kg-1）， high-dose， medium-dose， and low-dose （31.9， 19.1， 6.4 g·kg-1） MGQT groups， with 10 in each group， and the drug dose was10 mL·kg-1. The model group and the blank group received distilled water of the same volume. The administration lasted 12 weeks （once/day）. Fasting blood glucose （FBG） was detected regularly. After 12 weeks of administration， serum levels of glycated serum protein （GSP）， serum glucose （GLU）， total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） were detected. Pathological changes in the pancreatic tissue were based on hematoxylin-eosin （HE） staining.

The mouse model was made by gavage of mixed antibiotics for 7 d， and the low-dose and high-dose Wumeisan groups （5.98， 11.96 g·kg-1） were given gavage for 7 d continuously. The normal group and the model group were given the same volume of sterile water. The changes in the body weight， food intake， and diarrhea of mice were recorded. Feces were collected after the last administration， and the lactase activity was detected by the colorimetric method. The gut microbiota changes were detected by the 16S rRNA high-throughput sequencing technology.ResultCompared with those in the normal group， the mice in the model group had dilute and soft stools， reduced body mass， reduced food intake， reduced lactase activity， significantly reduced intestinal flora diversity， and significant changes in the relative abundance phylum and genus levels of flora. Compared with the model group， Wumeisan reduced the diarrhea rate of mice， promoted the rapid recovery of body weight and food intake， increased the lactase activity decreased by antibiotic， improved the community abundance and diversity of mice with dysbacteriosis， and made the species composition closer to that in the normal group. The abundance of three phyla （Bacteroidota， Proteobacteria， Verrucomicrobiota） and nine genera （Odoribacter， Enterococcus， Clostridium innocuum group， etc.） of mice with diarrhea were regulated by Wumeisan. Among them， norank f Muribaculaceae， norank f norank o Clostridia UCG-014， Lachnospiraceae NK4A136 group， and Odoribacter showed significant positive correlation with the body weight and lactase activity， and Escherichia-Shigella， Enterobacter， Enterococcus， and Clostridium innocuum group showed significant positive correlation with the diarrhea rate. Function prediction showed that the high-dose Wumeisan significantly reseted 6 functional levels of metabolism， genetic information processing， and human diseases， and had positive effects on endocrine and metabolic diseases， immune diseases， infectious disease， and parasitic infectious diseases.ConclusionWumeisan can relieve the symptoms of dysbacteriological diarrhea by increasing the lactase activity and regulating the gut microbiota composition.关键词：Wumeisan;dysbacteriological diarrhea;gut microbiota;lactose;high-throughput sequencing

Based on immunofluorescence staining and Western blot （WB）， the expression of epithelial mesenchymal transition （EMT）-related proteins in A549 and A549/DDP groups was observed. A549/DDP cells were classified into control group， FYN group （200 mg⋅L-1）， DDP group （6.0 mg⋅L-1）， and combination group ［FYN （200 mg⋅L-1） + DDP （6.0 mg⋅L-1）］ and respectively treated with corresponding drugs. Then， invasion ability of each group was examined by transwell assay， and the expression of EMT-related proteins in each group by WB. Moreover， real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） and immunofluorescence staining were separately applied to detect the mRNA and protein expression of drug resistance-related factors in each group， respectively.ResultCompared with A549 group， A549/DDP group showed high resistance to DDP （P<0.01）， low expression of E-cadherin， and high protein expression of Vimentin， N-cadherin， and Snail （P<0.05， P<0.01）. As compared with the control group， FYN inhibited the proliferation of A549/DDP cells in a concentration-dependent manner （P<0.01）， and the FYN group， DDP group， and combination group demonstrated low invasion ability （P<0.01）. In addition， the invasion ability in the combination group was particularly lower than that in the DDP group （P<0.01）. The expression of E-cadherin protein was higher and the protein expression of N-cadherin， Vimentin， and Snail was lower in the in FYN group than in the control group （P<0.01）. The protein expression of E-cadherin， N-cadherin， and Vimentin was lower and the expression of Snail was higher in the DDP group than in the control group （P<0.05，P<0.01）. The protein expression of E-cadherin， N-cadherin， Vimentin， and Snail in the combination group decreased as compared with that in the control group （P<0.01）. Compared with the DDP alone， the combination raised the expression of E-cadherin and lowered the protein expression of N-cadherin， Vimentin， and Snail （P<0.01）. The protein and mRNA expression of lung resistance-related protein （LRP） and multidrug resistance 1 （MDR1） was lower and the protein and mRNA expression of topoisomerase Ⅱα （TOPO Ⅱα） was higher in the FYN group than in the control group （P<0.01）. The protein and mRNA expression of LRP， MDR1， and TOPO Ⅱα was higher in the DDP group than in the control group （P<0.01）. The expression of LRP protein and mRNA showed no significant variation， but the protein and mRNA expression of MDR1 and TOPO Ⅱα increased in the combination group compared with those in the control group （P<0.01）. Compared with the DDP group， FYN group and combination group showed low protein and mRNA expression of LRP and MDR1 and high protein and mRNA expression of TOPO Ⅱα （P<0.01）. Compared with FYN， the combination elevated the protein and mRNA expression of LRP， MDR1， and TOPO Ⅱα （P<0.01）.ConclusionFYN prescription can reverse the DDP resistance of NSCLC by modulating EMT.关键词：Feiyanning （FYN）;non-small cell lung cancer （NSCLC）;drug resistance;epithelial mesenchymal transition （EMT）;cisplatin （DDP）

The model group was given intraperitoneal injection of cyclophosphamide （50 mg·kg-1 loading dose on the 1st day+8 mg·kg-1 low-dose maintenance on the 2nd–15th days）. After successfully modeling， the rats were randomly divided into model group， positive drug （progynova） group （0.1 mg·kg-1·d-1）， and low-， medium-， and high-dose Zhuluan decoction groups （14， 28， 56 g·kg-1·d-1 ）， with 10 rats in each group. The model group and the normal group were given equal volume of distilled water by gavage， once a day， continuous administration for 21 d. The estrous cycle and body weight of rats in each group were detected， and the ovarian organ index and uterine organ index were calculated. The ovarian tissue pathology and ovarian follicle counts at all levels were determined by hematoxylin-eosin （HE） staining. The content of the serum antimullerian hormone （AMH）， follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and inhibin-B （INH-B） of rats was determined by enzyme-linked immunosorbent assay （ELISA）， and the protein expression levels of PI3K， Akt， mTOR in the rat ovarian tissue were determined by Western blot. The microtubule-associated protein 1 light chain 3B （LC3B） protein expression in the rat ovarian tissue was determined by immunohistochemistry.ResultAs compared with the blank group， the estrous cycle of rats in the model group was disordered， the body weight， ovarian organ index， and uterine organ index decreased， the number of primordial follicles decreased， and the number of secondary follicles and atretic follicles increased. In the model group， FSH increased （P<0.01）， LH increased （P<0.05）， AMH level decreased （P<0.05）， the protein expression levels of PI3K， Akt， and mTOR in the ovarian tissue decreased （P<0.01）， and the protein expression level of LC3B increased significantly （P<0.01）. As compared with the model group， the above indexes were improved in the progynova group and different doses of Zhuluan decoction groups， the content of AMH increased （P<0.05）， and FSH decreased （P<0.05）. In the progynova group and different doses of Zhuluan decoction groups， the protein expression level of LC3B decreased obviously （P<0.01）， and the protein expression levels of PI3K， Akt， and mTOR all showed an increasing trend. Moreover， there was a statistically significant difference in the progynova group and low- and medium-dose Zhuluan decoction groups （P<0.05）.ConclusionZhuluan decoction may inhibit the occurrence of excessive autophagy in ovarian granulosa cells by activating the PI3K/Akt/mTOR pathway， thereby reversing the effect of modeling on ovarian reserve in rats.关键词：premature ovarian insufficiency;Zhuluan decoction;Bingshan theory;phosphatidylinositol-3-kinases/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway;autophagy

The DVT model was induced in rats of the modeling group by slowing down blood flow and damaging vascular endothelium. The model rats were randomly divided into model group， aspirin group （200 mg·kg-1）， and low-，medium-， and high-dose Qihong Tongluo prescription groups （6.5， 13， 26 g·kg-1） according to a random number table. Rats were treated with corresponding drugs by gavage， while those in the model group and the blank group received normal saline， once per day for 7 days. The rats were sacrificed and the abdominal aortic blood was taken. The levels of serum endothelin-1 （ET-1） and interleukin-6 （IL-6） were detected by enzyme-linked immunosorbent assay （ELISA）. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in vascular endothelial tissues. The ultrastructure of vascular endothelial cells was observed by the transmission electron microscope. The viability of vascular endothelial cells was detected by methylthiazolyldiphenyl-tetrazolium bromide （MTT） method，and the release level of lactate dehydrogenase （LDH） was detected by the LDH kit. The messenger ribonucleic acid （mRNA） expression of platelet-activating factor （PAF），nuclear transcription factor κB （NF-κB），Ras-related C3 botulinum toxin substrate 1 （Rac1）， and Ras-related C3 botulinum toxin substrate 2 （Rac2） in vascular endothelial tissues were detected by real-time reverse transcription polymerase chain reaction （Real-time PCR）. The protein expression of PAF，NF-κB，Rac1， and Rac2 in vascular endothelial tissues was detected by Western blot.ResultThe model group showed seriously damaged and swollen vascular endothelial cells with massive shedding， attachment of massive inflammatory cells， nucleus pyknosis and deformation under the electron microscope， highly swollen mitochondria， serious cytoplasmic vacuolation，and exposure of internal elastic membrane. The damage of vascular endothelium and its ultrastructure in Qihong Tongluo prescription groups and the aspirin group was improved in varying degrees. Compared with the blank group，the model group showed increased levels of serum ET-1 and IL-6，potentiated vascular endothelial cell viability， up-regulated mRNA and protein expression of PAF，NF-κB，Rac1， and Rac2 in vascular endothelial tissues，and decreased LDH release level of vascular endothelial cells （P<0.05）. Compared with the model group，the aspirin group and the Qihong Tongluo prescription groups showed decreased levels of serum ET-1 and IL-6，blunted vascular endothelial cell viability，down-regulated mRNA and protein expression of PAF，NF-κB，Rac1， and Rac2 in vascular endothelial tissues，and increased LDH release level of vascular endothelial cells （P<0.05）. The effect of Qihong Tongluo prescription was dose-dependent.ConclusionQihong Tongluo prescription has a protective effect on vascular endothelial cells of DVT rats and can prevent and treat thrombosis，and its therapeutic effect is presumably achieved by inhibiting the expression of PAF，NF-κB，Rac1，and Rac2 and reducing the levels of serum ET-1 and IL-6.关键词：Qihong Tongluo prescription;deep venous thrombosis;vascular endothelial cells;platelet-ctivating factor;nuclear transcription factor- κB;Ras related C3 botulinum toxin substrate 1;Ras related C3 botulinum toxin substrate 2;Buyang Huanwutang

Thiazole blue （MTT） assay and colony formation assay were used to evaluate the proliferation of A549 cells. Apoptosis was observed based on Hoechst 33258 staining， flow cytometry， and Annexin V-FITC/PI staining. Western blot was employed to detect the expression of apoptosis-related proteins cysteine-aspartic acid protease-3 （Caspase-3）， B-cell lymphoma-2 （Bcl-2）-associated X protein （Bax）， and Bcl-2， and the expression of PI3K， phosphorylated （p）-PI3K， Akt， p-Akt， JNK， p-JNK， p38 MAPK， and p-p38 MAPK.ResultCompared with the blank group， STA groups （150， 200， 250， 300 mg⋅L-1） demonstrated the increase in inhibition rate of cell proliferation （P<0.01） and cell clone inhibition rate， and decrease in cell clone formation rate （P<0.01）. In comparison with the blank group， STA groups showed typical characteristics of apoptosis， such as chromatin condensation and enhanced fluorescence reaction. The apoptosis rate of STA groups was significantly higher than that of the blank group （P<0.01）.

Moreover， the model group had less urinary D-xylose excretion， lower serum levels of GAS， TP， ALB， and HDL-C， higher levels of TC， LDL-C， AVP， and IL-6， lower expression of Na+-K+-ATPase in the liver， and higher expression of AQP1 in renal medulla than the blank group （P<0.05， P<0.01）. The three OA groups demonstrated better general conditions， faster weight gain， more frequent spontaneous activities， lower water content in feces and tissues， larger weight loss after water loading， and lower coefficient of each organ than the model group （P<0.05， P<0.01）. Moreover， compared with the model group， the three OA groups had high D-xylose excretion， high serum levels of GAS， TP， ALB， and HDL-C， low serum levels of TC， LDL-C， AVP， and IL-6， high expression of Na+-K+-ATPase in liver， and low expression of AQP1 in renal medulla （P<0.05， P<0.01）. The recovery in each OA group was better than that in natural recovery group. Molecular docking results also confirmed that OA had high binding affinity with ALB， IL-6， AQP1， and Na+-K+-ATPase.ConclusionOA can alleviate the abnormal water metabolism in mice with water-dampness retention caused by spleen deficiency， which lays a basis for its potential clinical application.关键词：oleanolic acid;spleen deficiency;water-dampness retention;abnormal water metabolism;mice

摘要：ObjectiveTo explore the clinical efficacy of compound Wufengcao liquid （CWL） on tuberculous ulcer and the influence on macrophage polarization.Method① Clinical experiment： A total of 145 patients with tuberculous ulcer who were treated in Nanjing Integrated Traditional Chinese and Western Medicine Hospital were randomized into observation group， control group Ⅰ， and control group Ⅱ according to the random number table method. In addition to the basic anti-tuberculosis chemotherapy， CWL， Kangfuxin liquid， and isoniazid solution （local external application） were respectively used in the observation group， control group Ⅰ， and control group Ⅱ. The treatment lasted 4 weeks for each group. The total effective rate in wound healing， traditional Chinese medicine（TCM） syndrome score， and histopathological morphology of wound were observed and the expression of inducible nitric oxide synthase （iNOS） and arginase-1 （Arg-1） in wound tissue was measured. ② Cell experiment： RAW264.7 cells were cultured in DMEM （10% fetal bovine serum， 1% double-antibody solution） in a cell incubator （37 °C， 5% CO2）. Phorbol 12-myristate 13-acetate （PMA） was used to induce the differentiation of RAW264.7 cells into macrophages. Lipopolysaccharide （LPS） was employed to stimulate polarization of macrophages into M1 type and interleukin-4 （IL-4） to induce the polarization into M2 type. Kangfuxin solution， isoniazid solution， and CWL were respectively applied to the above cell model for 36 h. The cell supernatant was collected and centrifuged. Western blot was used to detect the protein expression of tumor necrosis factor-α （TNF-α）， transforming growth factor-β （TGF-β）， iNOS， and Arg-1， and flow cytometry （FCM） to detect the expression of CD86 and CD206.Result①Clinical experiment： The total effective rate in the CWL group ［98.0% （48/49）］ was higher than that in the control group Ⅰ ［87.5% （42/48）， χ2=3.962， P<0.05］ and control group Ⅱ ［83.3% （40/48）， χ2=6.162， P<0.05］. After 28 days of treatment， compared with control group Ⅰ and control group Ⅱ， CWL decreased the TCM syndrome score （P<0.05） and obviously improved the histopathological morphology of the wound. Immunohistochemistry results showed that the iNOS expression in local focus tissue was lower （P<0.05） and the expression of Arg-1 was higher （P<0.05， P<0.01） in the CWL group than in the control group Ⅰ and control group Ⅱ after 28 days of treatment. ② Cell experiment： Western blot assay showed that the expression of iNOS and TNF-α in LPS group increased compared with that in the M0 group （P<0.01） and the expression in the LPS+ isoniazid group， LPS+ Kangfuxin group， and LPS+CWL group was lower than that in the LPS group （P<0.05）. The expression of iNOS in LPS+Kangfuxin group and LPS+ CWL group was lower than that in the LPS+isoniazid group （P<0.05， P<0.01）， and the expression of TNF-α in LPS+ CWL group was lower than that in LPS+isoniazid group （P<0.01）. The expression of TNF-α in LPS+ CWL group decreased compared with that in the LPS+ Kangfuxin group （P<0.05）. The expression of Arg-1 and TGF-β in IL-4 group was higher than that in the M0 group （P<0.01）， and the expression in the IL-4+isoniazid group， IL-4+Kangfuxin group， and IL-4+ CWL group was higher than that in the IL-4 group （P<0.05）. The expression of Arg-1 and TGF-β in the IL-4+ Kangfuxin group and IL-4+CWL group was higher than that in the IL-4+isoniazid group （P<0.05， P<0.01）， and the expression was higher in the IL-4+CWL group than in the IL-4+Kangfuxin group （P<0.05， P<0.01）. The FCM result showed that the expression of CD86 and CD206 in LPS group and IL-4 group was higher than that in M0 group （P<0.01）. CD86 expression in LPS+isoniazid group， LPS+ Kangfuxin group， and LPS+CWL group was lower than that in the LPS group （P<0.01）. The expression of CD86 in LPS+Kangfuxin group and LPS+ CWL group increased compared with that in the LPS+isoniazid group （P<0.01）， and the expression was higher in the LPS+ CWL group than in the LPS+Kangfuxin group （P<0.01）. CD206 expression in IL-4+ isoniazid group， IL-4+Kangfuxin liquor group， and IL-4+ CWL group was increased compared with that in the IL-4 group （P<0.01）. CD206 expression in IL-4+Kangfuxin liquid group and IL-4+ CWL group was decreased compared with that in the IL-4+isoniazid group （P<0.01）. CD206 expression in IL-4+CWL group was lower than that in the IL-4+ Kangfuxin group （P<0.05）.ConclusionCWL can promote the healing of tuberculous ulcers， and the mechanism is that it inhibits the expression of iNOS， TNF-α， and CD86 and promotes the expression of Arg-1， TGF-β， and CD206， thereby regulating M1/M2 polarization balance.关键词：Compound Wufengcao Liquid;tuberculous ulcer;macrophage polarization;chronic sore- 30

The patients in the observation group were treated with herb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription，while those in the control group received levocarnitine oral liquid. The primary observation indicators included spouse pregnancy rate，progressive motility （PR），and total sperm motility，and the secondary observation indicators included sperm DNA fragmentation index （DFI），SOD in the seminal plasma， and improvement of TCM syndromes. The treatment cycle was 12 weeks. Before and after treatment，the PR，total sperm motility，sperm DFI，SOD in the seminal plasma， and TCM syndrome scores were recorded. The patients were followed up for 12 weeks and the pregnancy status of spouses within 24 weeks （half a year） was recorded. The clinical efficacy of the two groups was evaluated.ResultThe pregnancy rate of spouses in the observation group was 15.69% （8/51）， higher than 3.85% （2/52） in the control group （χ2=4.118，P<0.05）. The total effective rate of the observation group was 88.24%（45/51）， superior to 69.23% （36/52）in the control group （Z=-3.402，P<0.01）. After treatment， PR， total sperm motility，sperm DFI， SOD in the seminal plasma， and TCM syndromes of the two groups were improved compared with those before treatment （P<0.05）， and the observation group was superior to the control group （P<0.05）.ConclusionHerb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription in the treatment of iAZS-induced infertility patients with kidney-Yang deficiency and collateral obstruction syndrome can increase PR，total sperm motility， and SOD level in the seminal plasma， reduce sperm DFI，improve the TCM symptoms of patients， and improve the pregnancy rate of spouses. The mechanism may be attributed to the fact that this treatment can increase the SOD level in the seminal plasma of patients，enhance the body's antioxidant function，protect sperm from oxidative stress damage，and reduce sperm DFI.关键词：male infertility;kidney-Yang deficiency and collateral obstruction;herb-partitioned moxibustion method on the navel;idiopathic asthenozoospermia;Yishen Tongluo prescription

发布时间：2023-01-17 - 摘要：ObjectiveChronic heart failure （CHF） is the terminal stage of cardiovascular disease. The adverse cardiovascular events of CHF patients with weakness have increased significantly. Traditional Chinese medicine （TCM） has a good effect on CHF. However，there are few reports on the clinical observation of the treatment of CHF with weakness in elderly patients by TCM combined with conventional health-preserving exercises. This study aimed to explore the clinical efficacy of Qiangxin decoction combined with Baduanjin in the treatment of elderly patients with CHF and weakness.MethodSixty CHF patients with Qi deficiency，blood stasis，and water retention syndrome admitted to the Cardiovascular Department of the First Affiliated Hospital of Guangxi University of Chinese Medicine from January 2020 to December 2021 were enrolled. The patients in the control group were treated with conventional western medicine according to the guidelines，while those in the treatment group received additional Qiangxin decoction and Baduanjin exercise based on the therapeutic protocol of the control group. The levels of serum N-terminal B-type brain natriuretic peptide precursor （NT-proBNP），creatine kinase （CK），lactate dehydrogenase （LDH），free fatty acid （FFA），left ventricular ejection fraction （LVEF），left ventricular end-diastolic dimension （LEVDD），6-minute walk distance （6MWD），Minnesota Living with Heart Failure Questionnaire （MLHFQ）， and Tilburg Frailty Indicator （TFI） scores of the two groups were observed before and one month after treatment. At the same time，the re-admission within three months was compared between the two groups.ResultThere was no significant difference between the two groups in terms of the general data and the therapeutic indexes before treatment. After treatment，the NT-proBNP，CK，LDH，FFA，LVEDD，MLHFQ， and TFI scores of the two groups were lower than those before treatment（P<0.05，P<0.01）， and the LVEF and 6MWD were higher（P<0.05，P<0.01）. The efficacy of the treatment group was superior to that of the control group after treatment （P<0.05，P<0.01）. The re-admission rate within three months in the treatment group was 7.1% （2/28）， lower than 30.8% （8/26） in the control group （χ2=4.897，P<0.05）.ConclusionQiangxin decoction combined with Baduanjin is helpful to improve the body energy metabolism，heart function，quality of life，and weakness level of elderly CHF patients with weakness， and reduce the rate of re-admission.关键词：chronic heart failure;weakness;Qiangxin decoction;Baduanjin;clinical observation

The treatment group was given Yishen Yangxin Anshen tablets and the control group received placebo tablets （4 tablets/time， 3 times/day， 4 weeks of administration， 4 weeks of follow-up after drug withdrawal）. The sleep dysfunction rating scale （SDRS） score， pittsburgh sleep quality index （PSQI） score， TCM， polysomnography （PSG） indicators from four hospital （Guang'anmen Hospital， China Academy of Chinese Medical Sciences， Henan Province Hospital of TCM， Hebei General Hospital， The First Hospital of Hunan University of Chinese Medicine）， and other efficacy indicators were compared between the two groups before and after treatment. Through general physical examination， laboratory examination， and observation of adverse events， the safety of the drugs was evaluated.ResultThe baseline indexes of the two groups showed no significant difference and thus the two groups were comparable. After treatment， the total score of SDRS in the treatment group was lower than that in the control group （P<0.01）. After drug withdrawal for 4 weeks， the total score of SDRS demonstrated no significant change in the treatment group as compared with that at the end of treatment， indicating that the rebound change of curative effect was not obvious. After treatment， the total score of PSQI in the treatment group decreased as compared with that in the control group （P<0.01）， and the change of total score of PSQI in the treatment group was statistically significant （P<0.05） after drug withdrawal for 4 weeks but small， indicating that the rebound change of curative effect was not obvious. After treatment， the total effective rate about the TCM symptoms in the treatment group was higher than that in the control group （χ2=137.521，P<0.01）. After treatment， the disappearance rates of single indexes in the treatment group， such as difficulty in falling asleep， easily waking up after sleeping， early awakening， short sleep time， dreamfulness， palpitation， forgetfulness， dizziness， mental fatigue， and weakness of waist and knee， increased compared with those in the control group （P<0.01）. After treatment， the treatment group demonstrated fewer awaking times （AT）， longer total sleep time （TST）， lower ATA/TST ratio， and higher sleep efficiency （%） than the control group （P<0.05）. No abnormal value or aggravation related to drugs was observed in either group. The incidence of adverse events in the treatment group and the control group was 5.57% and 8.40% respectively. No serious adverse events or adverse events leading to withdrawal happened in either group.ConclusionYishen Yangxin Anshen tablets is effective and safe for patients with insomnia of deficiency of heart-blood and insufficiency of kidney-essence.关键词：Yishen Yangxin Anshen tablets;insomnia;randomized double-blind;placebo-controlled;multi-center clinical trial

发布时间：2023-01-17 - 摘要：ObjectiveThrough the targeted lipidomics， we explored the intervention mechanism of Kaixuan Bushen method on psoriasis vulgaris （PV） from the perspective of lipid metabolism， providing reference for the diagnosis and treatment of PV.MethodTwenty-six patients with PV admitting the outpatient clinic of the Department of Dermatology， Guang'anmen Hospital， China Academy of Chinese Medical Sciences from September 2019 to November 2020 were selected as the research object （observation group）， and 26 sex- and age-matched healthy volunteers in the same period were recruited as control group. Venous blood was collected for lipid index and targeted lipidomics detection in the control and observation groups at inclusion. After 12 weeks of continuous treatment of Kaixuan Bushen method， the psoriasis area and severity index （PASI） was measured and compared before and after treatment to assess the clinical efficacy， while venous blood was collected again in the observation group to compare the blood lipid level and lipid metabolism of patients before and after treatment. Targeted lipidomics analysis was performed by ultra performance liquid chromatography tandem mass spectrometry （UPLC-MS/MS） on an ACQUITY UPLC BEH C8 column （2.1 mm×100 mm， 1.7 μm） with mobile phase of 5 mmol∙L-1 ammonium formate in acetonitrile-water （6∶4， A）-5 mmol∙L-1 ammonium formate in acetonitrile-isopropanol （1∶9， B） for gradient elution and flow rate of 0.26 mL∙min-1. Conditions of MS were electrospray ionization （ESI）， positive and negative ion modes， and scanning range of m/z 50-1 200. Then principal component analysis （PCA） and partial least squares-discriminant analysis （PLS-DA） models were developed to screen differential metabolites， and the differential metabolites were identified and the pathways were enriched.ResultAfter 12 weeks of treatment with Kaixuan Bushen method， PASI score decreased by more than 50% in a total of 22 out of 26 patients with PV， suggesting the total effective rate was 84.62%. The serum triglyceride level of patients with PV was significantly higher than that of healthy individuals （P<0.05）， and the triglyceride level was significantly reduced after treatment （P<0.05）. Targeted lipidomics analysis screened a total of 43 potential biomarkers for PV， of which 42 were up-regulated and 1 was down-regulated， involving 7 signaling pathways such as linoleic acid metabolism， glycerophospholipid metabolism and unsaturated fatty acid biosynthesis. Moreover， there were 14 response makers for clinical efficacy of Kaixuan Bushen method on PV， of which 6 were up-regulated and 8 were down-regulated， involving five signaling pathways such as linoleic acid metabolism， glycerophospholipid metabolism and sphingolipids metabolism. In a comparison between healthy individuals and patients with PV and PV before and after treatment， the common differential metabolites were screened as phosphatidylcholine （PC） 38∶0 and ceramide （Cer） 42∶1， and the common pathways were linoleic acid and glycerophospholipid metabolic pathways.ConclusionThe disorder of lipid metabolism in PV are largely due to abnormal sphingolipid， glycerophospholipid and linoleic acid metabolic pathways， of which Kaixuan Bushen method can regulate the glycerophospholipid and linoleic acid metabolism， thereby improving psoriatic lesions.关键词：targeted lipidomics;psoriasis vulgaris;Kaixuan Bushen method;biomarkers;linoleic acid metabolism;glycerophospholipid metabolism

Then， high-quality transformants were selected. Orthogonal test was used to optimize the colonization conditions by taking co-culture temperature， co-culture time and spore concentration as factors and colonization rate as index.ResultWhen spore concentration was 1×107 cfu·mL-1， acetosyringone concentration was 150 μmol·L-1 and the co-culture time was 60 h， the transformation efficiency of C. rosea was the highest， which was 135 transformants per 1×107 recipient fungal spores. The accuracy and stability of the transformations were tested by cloning the marker gene green fluorescent protein （GFP） and β-glucuronidase （GUS） staining. When co-culture temperature was 25 ℃， co-culture time was 36 h and the spore concentration was 1×106 cfu·mL-1， the colonizing rate for C. rosea back dyeing into G. uralensis seeds by seed soaking method was the highest， which was 71.11%.ConclusionThis study successfully establishes stable and efficient technical systems not only of ATMT in C. rosea， but also of colonization of the transformants into G. uralensis seeds， which can lay a foundation for the development of biofertilizer of G. uralensis.关键词：Clonostachys rosea;Agrobacterium tumefaciens-mediated transformation （ATMT）;green fluorescent protein;β-glucuronidase （GUS） staining;Glycyrrhiza uralensis;transformant;orthogonal test

The effects of a compound microbial fertilizer on the agronomic properties， the content of active ingredients， the number of rhizosphere soil bacteria， Actinomycetes， and fungi， and soil physicochemical properties of A. paniculata were studied.ResultAs compared with the CK group and the treatment A group， the plant height， leaf number， leaf area， and above-ground and below-ground fresh weight of A. paniculata were significantly increased after microbial fertilization， with differences in different growth periods. The effect of the compound microbial fertilizer on the content of andrographolide， dehydrated andrographolide， neandrographolide， and 14-deoxyandrographolide differed. The content of andrographolide significantly increased by 26.13% and 13.23% in the treatment C group， respectively， as compared with the CK group and the treatment A group （P<0.05）. The content of neandrographolide increased with the increasing amount of microbial fertilizer， and the content in the treatment D group increased by 9.06% and 50.33%， respectively， as compared with the CK group and the treatment A group （P<0.05）， which was the most obvious. The content of 14-deoxyandrographolide in the treatment B group significantly increased by 42.04% and 1.74%， respectively， as compared with the treatment A group and the CK group （P<0.05）. The content of dehydrated andrographolide content in the treatment B group increased most significantly， significantly increasing by 11.73% and 27.74%， respectively， as compared with the CK group and the treatment A group （P<0.05）. The soil pH of the treatment B， C， and D groups was higher than that of the CK group and the treatment A group. The content of total nitrogen and effective phosphorus increased most significantly in the treatment B group， and the content of fast-acting potassium increased most significantly in the treatment D group. The application of the compound microbial fertilizer increased the number of rhizosphere soil bacteria and Actinomycetes， which was significantly higher than that in the CK group and the treatment A group （P<0.05）， and increased with the increase of applied amount. The number of fungi decreased with the increase of the compound microbial fertilizer application， which was significantly different from that in the CK group （P<0.05）. The fungi/bacteria of all treatment groups were significantly lower than those of the CK group （P<0.05） and increased with the increase of microbial fertilizer application.ConclusionThe application of the compound microbial fertilizer transforms the plant-soil-microbial system in a benign direction， which is beneficial to the growth of A. paniculata and the accumulation of active ingredients.关键词：Andrographis paniculata;compound microbial fertilizer;agronomic properties;active ingredients;soil microorganism

发布时间：2023-01-17 - 摘要：ObjectiveTo clone coumarate-3-hydroxylase gene （C3H） from Angelica sinensis， and analyze the correlation between its bioinformatics， expression patterns and content of ferulic acid， and to explore the functions of ASC3H.MethodReal-time polymerase chain reaction （Real-time PCR） was used to clone the full-length cDNA of ASC3H based on the transcriptome dataset of A. sinensis， and the bioinformatics analysis of the gene sequence was carried out. Real-time PCR and high performance liquid chromatography （HPLC） were used to determine relative expression of ASC3H and content of ferulic acid in different root tissues of A. sinensis （periderm， cortex and stele）.ResultThe open reading frame （ORF） of ASC3H （GenBank accession number： MN2550298） was 1 530 bp， encoding 509 amino acids， with a theoretical molecular weight of 57.86 kDa and an isoelectric point of 8.36. It was a hydrophilic protein that was located in the chloroplast with multiple phosphorylation sites and a transmembrane region， and contained a conserved domain CGYDWPKGYGPIINVW_P450 （383-399 aa） in cytochrome P450. Multiple amino acid sequence alignment analysis showed that ASC3H had high similarity with C3H from other plants， especially Ammi majus in Umbelliferae. The Real-time PCR revealed that ASC3H had different expressions in periderm， cortex and stele tissues of A. sinensis roots. It was found from HPLC that the cortex tissues had the highest content of ferulic acid， and the stele tissues had the lowest.ConclusionASC3H was successfully cloned from A. sinensis， and its sequence characteristics were understood more clearly， suggesting that ASC3H might be involved in the ferulic acid biosynthesis pathway of A. sinensis. This paper provided a basis for further studying the functions of the gene and exploring the biosynthesis and regulation mechanism of ferulic acid in A. sinensis， while laying the foundation for the genetic improvement of A. sinensis．关键词：Angelica sinensis;ferulic acid;coumarate-3-hydroxylase （C3H）;gene cloning;bioinformatics analysis;expression analysis;content determination

发布时间：2023-01-17 - 摘要：Safety is the core of the quality of Chinese materia medica products， and microbial pollution caused by medicinal materials， decoction pieces， intermediate products and others can bring certain impact on the quality and safety of Chinese materia medica products. The reasons for this are not only the problems of medicinal materials themselves， but also the exogenous pollution introduced in the production process. How to effectively use microbial detection technology and establish an appropriate microbial quality control strategy in the whole process of Chinese materia medica production is of great significance to improve the quality of Chinese materia medica products. Therefore， the authors put forward a microbial quality control strategy in the whole process of Chinese materia medica production based on the guidance of quality by design （QbD） concept， emphasizing the scientific linkage between the internal and external microbial quality control systems to jointly ensure the quality of products in all aspects. Among them， the internal microbial quality control system includes the control of the whole chain of Chinese materia medica-decoction pieces-intermediate products-excipitents-packaging materials-final products， which should be carried out by stages and characteristics， while the external microbial quality control system includes the control of personnel-equipment and facilities-pharmaceutical water-environment， emphasizing the principle of quality risk management and the development of monitoring programs， aiming to closely integrate microbial quality risk management with the production process of Chinese materia medica products， and to classify and develop microbial control strategies in order to minimize the impact of contaminating microorganisms and effectively guarantee the quality of Chinese materia medica products.关键词：quality by design （QbD）;microbes;quality control;production of Chinese materia medica;rapid detection;safety;decoction pieces

发布时间：2023-01-17 - 摘要：Renal fibrosis is the main pathological foundation of chronic kidney diseases progressing to end-stage renal diseases. With complex pathogenic factors and prolonged disease course， it threatens the quality of life of patients and brings about heavy financial burden to medical care. In the instance of intestinal flora disturbance， the internal homeostasis is broken， resulting in various "imbalances". The "combination of state and target" endows the syndrome differentiation-based treatment of renal fibrosis with new connotation from the perspective of intestinal flora reconstruction and microbial diversity restoration. In addition， traditional Chinese medicine （TCM）-targeted intervention of intestinal microecology has unique advantages under the principle of "treating different diseases with the same method"， which can guide the diagnosis and treatment of renal fibrosis. To be specific， TCM emphasizes macroscopic regulation of state and microscopic targeting. In view of the inflammatory response， accumulation of endotoxin， and excessive deposition of extracellular matrix （ECM） in the process of renal fibrosis， the strategies for treating this disease have been developed， such as alleviating dampness，removing turbid toxin， and relieving deficiency and stasis. Famous prescriptions in ancient books or compound Chinese medicine prescriptions， classical formulas， Chinese medicine monomers， or active components of Chinese medicine target intestinal microecology. Therefore， from the perspective of common pathogenic factors of renal diseases （renal fibrosis） or pathological product-intestinal microecological imbalance， this article combines TCM basic theory with modern medical pathogenesis， and summarizes the research on TCM intervention of renal fibrosis by regulating intestinal microecology and the scientific connotation of renal fibrosis， which is expected to provide ideas and methods for the product development and related preparations and in-depth molecular biological research.关键词：combination of state and target;renal fibrosis;intestinal flora;treatment of different diseases with the same method;chronic kidney disease;traditional Chinese medicine

发布时间：2023-01-17 - 摘要：Vascular dementia （VaD） is a common disease that affects the health of the elderly. Due to the aging of the social population， the incidence of VaD is increasing year by year. There have been no officially approved treatments for this disease， mainly because its pathogenesis is complex， and the mechanism of action of effective drugs is not yet clear， which hinders drug research for the treatment of VaD. Therefore， by reviewing the available literature related to VaD， this study sorted out the pathogenesis of VaD from traditional Chinese medicine （TCM） and western medicine， and concluded that in TCM， VaD was characterized by the deficiency of the spleen and kidney （deficiency） and combination of phlegm and blood stasis （excess）， while in western medicine， the pathogenesis of VaD is mainly inflammatory response， oxidative stress， abnormal expression of related proteins， and dysfunction of signaling pathways. On this basis， this study also summarized the research on the mechanism of action of commonly used single Chinese herbal medicine and Chinese herbal medicine compound， western medicine， and the combination of Chinese herbal medicine and western medicine in the treatment of VaD in recent years. The commonly used single Chinese herbal medicine Ginkgo Folium and Chinese herbal medicine compound Dihuang Yinzi have the multi-component and multi-target characteristics and few adverse reactions in the treatment of VaD， while the commonly used western medicines such as donepezil and memantine have the characteristics of the clear target and quick onset. The combination of Chinese herbal medicine and western medicines can achieve a better effect. This study summarized the research on the pathogenesis and treatment of VaD， aiming to link the pathogenesis of VaD with the mechanism of effective drug therapy， and provide an important reference for future drug development for the treatment of VaD.关键词：vascular dementia;mechanism of action;pathogenesis;traditional Chinese medicine;review

Historical Evolution and Modern Research Progress of Processing of Notoginseng Radix et Rhizoma 增强出版
摘要：By reviewing the relevant literature of ancient herbal works and modern codices， this paper sorted out the historical evolution and developmental venation of processing of Notoginseng Radix et Rhizoma. On this basis， the modern research of processed products of Notoginseng Radix et Rhizoma was used as the breakthrough point to analyze the literature in terms of processing technology， chemical composition changes and changes in pharmacological effects before and after processing. According to the research status of processing of Notoginseng Radix et Rhizoma， some existing problems were analyzed in this paper， such as not many ancient processing methods used in modern time， lack of standardized research on processing technology. And saponins， polysaccharides， amino acids， flavonoids and other chemical components in Notoginseng Radix et Rhizoma may change to different degrees before and after processing， which was the main reason for the difference of efficacy before and after processing. However， the current research on the pharmacological effects of Notoginseng Radix et Rhizoma mainly focuses on raw products， resulting in a lack of in-depth research on the transformation mechanism of Notoginseng Radix et Rhizoma in processing difference， and the scientific connotation of "Shengxiao Shubu" has not been clearly elaborated， which is not conducive to the standardized clinical use of drugs. Therefore， it is necessary to further analyze the material basis of Notoginseng Radix et Rhizoma and its processed products， and to explore the change rule of chemical components before and after processing and its correlation with pharmacodynamic activity， so as to clarify the processing mechanism for providing scientific basis for its standardized processing， quality control and clinical rational use.关键词：Notoginseng Radix et Rhizoma;different uses of raw and processed products;historical evolution;processing method;Chinese Pharmacopoeia;material basis;mechanism of action- 33

发布时间：2023-01-17 - 摘要：Diabetic nephropathy （DN）， as one of the common chronic microvascular complications of diabetes， has become the main cause of renal failure in end-stage renal disease in China， increasing the risks of renal dialysis and kidney transplantation in diabetes patients. It is the leading cause of death in people with diabetes. The latest research on DN has focused on the gene level. microRNAs （miRNAs） are a family of endogenous accessible short-chain non-coding RNA molecules. By acting on a particular target， they activate or inhibit its mediated signaling pathways and related molecules， playing an important role in the occurrence and development of DN. They have become microeconomic factors for the prevention and treatment of DN. Traditional Chinese medicine （TCM） has a long history in the diagnosis and treatment of DN and has unique advantages such as significant curative effect and few side effects. A large number of studies have proved that TCM can target miRNA to affect multiple signaling pathways， participate in the regulation of inflammatory response， pyroptosis， mesenchymal transdifferentiation， and other pathological changes， and delay the further development of DN. Therefore， this study discusses the biogenesis mechanism of miRNA and its action mechanism in disease-related signaling pathways based on TCM diagnosis and treatment approaches from the perspective of miRNA， and summarizes the effect of TCM targeting miRNA on the disease-related signaling pathways and on DN. Thus， this study is expected to provide a theoretical reference for exploring the progress of TCM intervention in DN from the perspective of genes.关键词：diabetic nephropathy;microRNAs （miRNAs）;signaling pathway;traditional Chinese medicine

发布时间：2023-01-17 - 摘要：Diabetic kidney disease （DKD） is characterized by the hyperfiltration and albuminuria in the early phase which are followed by progressive renal function decline， renal tubular epithelial cell hypertrophy， and tubulointerstitial fibrosis. Thus， it is one of the leading causes of chronic kidney diseases. The currently available therapies mainly aim to control the primary diseases and reduce the risk of kidney injury. Based on syndrome differentiation， traditional Chinese medicine （TCM） relieves the symptoms by excreting water and alleviating edema and eliminates the root cause by tonifying deficiency and supplementing the original Qi， thereby showing therapeutic effect and delaying the progression of DKD. It excels in comprehensively regulating the constitution of patients with little side effects. Among the Zang-fu organs， kidney takes the second place in the content of mitochondria which participate in the metabolism of water and fluid and are the foundation of kidney Yin and kidney Yang. Mitochondria are energy producers within a cell， which carry out cellular respiration， produce reactive oxygen species， and generate adenosine triphosphate by oxidative phosphorylation. Mitochondrial quality control （MQC） is an effective way to maintain mitochondrial dynamic balance， whose imbalances， such as mitochondrial oxidative stress， mitophagy， mitochondrial dynamic changes， and abnormal calcium regulation， are related to the occurrence and development of DKD. It is generally believed that the destruction of mitochondrial structure in the case of metabolic disorder is the main cause of the disease. In recent years， TCM has attracted the attention of both Chinese and foreign researchers for the unique advantages of treating both symptoms and root cause at the same time and multi-target synergy in the treatment of DKD. However， the specific mechanism is still unclear. It has been frequently verified that mitochondria may be one of the targets of TCM in the treatment of DKD. At the moment， no review on the treatment of DKD by TCM through the intervention of MQC is available. Therefore， this paper aims to summarize the research on TCM treatment of DKD by regulating MQC in the past 10 years， which is expected to provide a new direction for the treatment of DKD by TCM.关键词：diabetic kidney disease （DKD）;mitochondrion;traditional Chinese medicine;review

发布时间：2023-01-17 - 摘要：Colorectal cancer （CRC） is one of the refractory malignant tumors of the digestive system worldwide. With limitations， the available clinical therapies are usually suspended or show unsatisfactory effect. Therefore， it is urgent to find and develop new candidate drugs specifically targeting the cancer with ideal efficacy， low toxicity， and low cost， and the solutions can be found in traditional Chinese medicine （TCM） which has a long history. In TCM， sovereign， ministry， assistant， and guiding medicinals are selected based on the syndrome differentiation， and it has shown remarkable efficacy on CRC in recent years. In particular， Chinese medicinal compounds and monomers from Chinese medicinals which have been applied in clinical settings are advantageous in the treatment of CRCs， as they improve the quality of life， alleviate clinical symptoms and toxic and side effects of chemotherapy， and prolong the survival of patients. Therefore， we retrieved the English and Chinese articles with "CRC"， "TCM"， "compound" and "monomer" as keywords， and summarized the progress in the treatment of CRC with Chinese medicinal compounds and monomers from Chinese medicinals from four aspects of "replenishing Qi and invigorating spleen"， "clearing heat and removing toxin"， "nourishing liver and kidney"， and "tonifying Qi and nourishing blood". However， Chinese medicine features multiple components， multiple targets， and multiple pathways， and in-depth research should be carried out on the application of Chinese medicinal compounds and monomers from Chinese medicinals in the treatment of CRC， in an attempt to minimize the pain and side effects and maximize the therapeutic effect. This study is expected to provide new insight into the treatment of CRC and a reference for further research on the efficacy and mechanism of Chinese medicine.关键词：colorectal cancer;traditional Chinese medicine （TCM） syndrome;syndrome differentiation;Chinese medicinal compound;monomer from Chinese medicinal

发布时间：2023-01-17 - 摘要：Embryo implantation is one of the most critical steps in the reproductive process. The failure of embryo implantation to continue development is one of the important reasons leading to infertility. The success of embryo implantation depends on the high receptivity of endometrium and the embryo with implantation ability. Autophagy is a process in which cytoplasm， organelles， and inclusions are absorbed by double-membrane vesicles and transported to lysosomes for degradation and recycling， which is a way to maintain the homeostasis. A large amount of evidence have shown that autophagy plays an important role in all aspects of embryo implantation. Based on this， this paper explored the relationship between autophagy and endometrial receptivity and embryo implantation ability. According to the latest research progress， this paper combed 5 mechanisms （promotion of decidualization of endometrial stromal cells， promotion of apoptosis， regulation of hormone levels， coordination of inflammation， and promotion of ovulation） of 14 kinds of Chinese medicine monomers， including emodin， catalpol， paeoniflorin， resveratrol， folic acid， zearalenone， curcumin， wogonin， quercetin， chrysin， berberine， apigenin， phisetine， and kaempferol， in regulating different links of autophagy intervention in embryo implantation. This paper is expected to provide references and ideas for future Chinese medicine monomers to improve the success rate of embryo implantation.关键词：embryo implantation;autophagy;Chinese medicine monomers;influence mechanism;review

发布时间：2023-01-17 - 摘要：Diabetic nephropathy （DN）， the most feared microvascular complication of diabetes and one of the most common and serious complications of diabetes， is the major cause of end-stage renal disease worldwide， leading cause of morbidity and mortality in patients with diabetes， and the main non-communicable cause of death worldwide. There are many types of saponins， which are the main bioactive components of various Chinese medicinals. They have various pharmacological activities such as lowering blood glucose and blood lipids， improving insulin resistance， anti-inflammation， anti-oxidative stress， anti-tumor， and immune modulation. In recent years， it has been frequently verified that the saponins in Chinese medicinals have definite effect in regulating DN， showing multi-target， multi-pathway， multi-system， multi-effect characteristics. Thus， they have broad prospects in the prevention and treatment of this disease. There has been an explosion of research on the treatment of DN with saponins in Chinese medicinals in vivo and in vitro， but there is a lack of systematic and comprehensive summary. Therefore， this study summed up the studies of saponins in Chinese medicinals in the intervention of DN and summarized the mechanisms such as improving glucolipid metabolism， inhibiting oxidative stress， anti-inflammation， anti-apoptosis， regulating autophagy， anti-fibrosis， and protecting podocytes， with a view to providing ideas and references for the development of drugs related to DN.关键词：saponins in Chinese medicinals;diabetic nephropathy;signaling pathway： mechanism
