摘要:Objective: In this study, a high efficient and rapid method was used to identify the origin of herbal medicines in order to safeguard our country's economic interests in the international trade. Method: Ultraviolet(UV) spectroscopy combined with principal component analysis(PCA) and partial least square discriminant analysis(PLS-DA) was used to discriminate the Swertia davidi which collected from different origins and establish the prediction model to predict the accuracy of the regions. The spectra data were imported into UV Probe 2.34 software to compare the same part of S. davidi. Raw and pre-processed data(8 point smoothing, the first derivative and the second derivative) were imported into SIMCA-P 11.5 and the effect of discrimination of origins was compared by 3D score plot of PCA. Result: PCA indicated that the raw and 8 point smoothing data of leaves showed the best classification and the cumulative contribution rate of the first three factors was 98.8%. The other pre-processed methods could not obtain better identification and it may be related to the cumulative contribution value(the cumulative contribution rate of the data processed by the first derivative was 83.9%while the second derivative was 47.3%). Samples from Chongqing and Hubei could be distinguished with that of Hunan by the data of roots, but the samples of Chongqing and Hubei could not be separated. The model of PLS-DA may provide the basis of discrimination of more origins. The validation set was imported into the model developed by the training set and it proved that the model was feasible and effective. In PLS-DA, the correlation index of predictive value and true value in the training set was 0.985 and the RMSEE was 0.159. The correlation index of predictive value and true value after importing the validation set in the training set was 0.972 and RMSEP was 0.327. Both RMSEE and RMSEP were similar and less than 0.500. So the model had high reliability. Conclusion: UV spectra combined with PCA and PLS-DA can discriminate S. davidi from different origins and the predicted effect of the model was better. Furthermore, samples with unknown origins could also be distinguished.

摘要:Objective: To provide technical reference for standardization planting and long-term storage of Salvia miltiorrhiza seed by studying seed structure, germination and storage characteristics. Method: In the study of morphology and structure, seeds and their paraffin sections were observed, and photos were taken by the dissecting microscope and electron microscope. In the study of germination, the optimal temperature and different light conditions were investigated. In the study of storage characteristics, the changes in seed viability at different water content and temperature conditions were investigated to determine optimal storage temperature and water content. Result: ① S. miltiorrhiza seeds can well germinate at 15-35℃, with the optimal temperature between 20-30℃. Fluctuating temperatures at 15/25℃ and 20/30℃ can increase the germination rate. Light can decrease the germination rate at high temperature. ② Low-temperature storage was better than room-temperature storage. Higher or lower water content could lead to the sharp decrease of seed viability. The optimal storage condition was 4℃, with 5%of water content. ③ The pericarp of S. miltiorrhiza consisted of the mucilage cell layer, the parenchyma cell layer, the single sclereid layer and the sclerenchyma cell layer. After absorbing water, the mucilage cells swelled, ruptured and released a lot of gelatinous mucus. Conclusion: S. miltiorrhiza has a wide seed germination temperature range, and can be planted in most areas of China. In seedling, fluctuating temperatures can be used to promote seed germination and increase the seedling emergence rate of S. miltiorrhiza. Temperature and water content are important factors in the storage of S. miltiorrhiza seeds. The optimal storage method is low temperature and low water content. The characteristics of S. miltiorrhiza seeds of rapidly absorbing a large amount of water were related to the structure of the mucilage cell layer. This structure is conducive to maintaining the seed moisture and resisting the drought, but bad for seed storage.

Hoechst33342 staining results showed prominent morphological changes with chromatin condensation, fragmentation and formation of apoptotic bodies in dose-dependent manner. Western blot analysis showed that Jiawei Sijunzi decoction containing serum could inhibit phosphorylation of Akt, mTOR, ribosomal S6 kinase(S6), and eukaryotic translation initiation factor 4E-binding protein 1(4EBP1), up-regulate the expression levels of Bax, and down-regulate the expression levels of CyclinD1, Bcl-2. Jiawei Sijunzi decoction containing serum and PI3K/mTOR dual inhibitor VS-5584 had a synergism effect, and Jiawei Sijunzi decoction containing serum enhanced the inhibitory effects on phosphorylation of Akt and mTOR. Conclusion: Jiawei Sijunzi decoction containing serum could inhibit the proliferation of Hep-G2 cells, induce apoptosis and arrest Hep-G2 cells in G1 phase. This inhibitory effect may be induced by blocking the PI3K/Akt/mTOR pathway.  
摘要:Objective: To study the role of anti-mullerian hormone(AMH) in immune premature ovarian failure(POF), investigate the effects of Zuogui Wan(ZGW), which is the kidney tonifying recipe, on AMH and its signal transduction pathway AMH/ALK2/Smad1 in POF mice, and explore the mechanism of ZGW on treating immune POF. Method: The 8 weeks old Balb/c female mice were randomly divided into normal group, model group, Estradiol valerate(trade name: progynova) group and ZGW group. POF animal models were established by zona pellucida 3 polypeptides and then were treated with ZGW or positive control medicine of progynova. The levels of AMH and follicule-stimulating hormone(FSH) in serum of mice were detected by electrochemical luminescence method.The follicle growth rate of the mice was detected by optical microscope. The expression levels of AMH, ALK2 and Smad1 in mouse ovary were detected by immunohistochemistry and Western blot assay. Result: As compared with the normal group, the AMH level was decreased and FSH level was increased in serum of model group mice(P<0.05). As compared with the model group, the AMH level was increased and FSH level was decreased in serum of ZGW group(P<0.05). As compared with the normal group, follicle growth rate was significantly decreased in model group mice(P<0.01). As compared with the model group, follicle growth rate was increased in ZGW group(P<0.05). As compared with the normal group, the protein expression levels of AMH, ALK2 and Smad1 were decreased in mice ovarian of model group(P<0.05). As compared with the model group, the protein expression levels of AMH were increased in mice ovarian of ZGW group(P<0.05); the expression levels of ALK2 and Smad1 were increased in the immunohistochemistry method, but the difference was not significant; the expression levels of both ALK2 and Smad1 were significantly increased in Western blot assay(P<0.05). Conclusion: The occurrence of POF was related to the insufficient secretion of AMH and poor expression of ovarian AMH protein. It affected the primordial follicle recruitment by affecting AMH/ALK2/Smad1 signal transduction, leading to fast follicle consumption, premature ovarian failure, and ovarian aging. ZGW can promote the secretion of AMH in POF mice, up-regulate AMH protein expression in ovary, inhibit the rapid collection and consumption of primordial follicles and improve ovarian function by affecting AMH/ALK2/Smad1 signal transduction.

Method: Sprague-Dawley rats were randomly divided into normal group, model group, colchicine group(1 mg·kg-1), PAMD high-dose group(25 mg·kg-1). PAMD medial-dose group(12.5 mg·kg-1) and PAMD low-dose group(6.25 mg·kg-1). Intraperitoneal injection of 40% CCl4(1 mL·kg-1) was used to induce hepatic fibrosis models in the rats. All the rats received the same volume of drugs or normal saline by intragastric administration for 30 days. The radioimmunoassay was used to determine the levels of hyaluronic acid(HA), laminin(LN), procollagen Ⅲ(PCⅢ) and collagen Ⅳ(CⅣ) in serum. The biochemical analysis was used to determine the levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST), total protein(TP) and album protein(ALB) in serum. The enzyme-linked immuno sorbent assay(ELISA) was applied to detect the levels of transforming growth factor-β1(TGF-β1) and tumor necrosis factor-α(TNF-α) in the liver tissues. Morphology of liver tissues was observed by optical electron microscopy, and the organ coefficients of liver and spleen were calculated then. Result: As compared with the normal group, the levels of HA, LN, PCⅢ, CIV, ALT and AST in serum were significantly increased in the serum of model group(P<0.05); levels of TP and ALB in serum were significantly decreased(P<0.05); levels of TGF-β1 and TNF-α in the liver tissues were significantly increased(P<0.05); the liver pathological fibrosis was aggravated significantly; organ coefficients of liver and spleen were significantly increased(P<0.05). As compared with the model group, the levels of HA, LN, PC-Ⅲ, CIV, ALT and AST in serum were significantly decreased in PAMD high-dose group and PAMD medial-dose group(P<0.05); the levels of TP and ALB in serum were significantly increased(P<0.05); levels of TGF-β1 and TNF-α in the liver tissues were significantly decreased(P<0.05); the liver pathological fibrosis was obviously relieved; organ coefficients of liver and spleen were significantly decreased(P<0.05). Conclusion: PAMD could attenuate the CCI4-induced immunological liver injury and the fibrosis level in rats. The mechanisms possibly contribute to down-regulating the expression levels of TGF-β1 and TNF-α proteins in liver tissues of rats.  
摘要:Objective: To observe the neuroprotective effects of cerebral ischemic preconditioning (CIP) on cerebral ischemia reperfusion and the expressions of brain-derived neurotrophic factor(BDNF), grial cell-lime derived neurotrophic factor(GDNF) and vascular endothelial growth factor(VEGF) in the cortex and hippocampus CA1 area of rats. Method: Wistar rats were randomly divided into three groups, Sham operation group, cerebral ischemia reperfusion (I/R) group, and cerebral ischemic tolerance (CIP+MCAO) group. The behavioral changes were detected by neurologic deficit scores (NDS), the cerebral histopathology was detected by HE staining, and the level of NSE in serum were detected by ELISA. The expressions of BDNF, GDNF and VEGF in cortex, hippocampus CA1 area were measured by immunohistochemical staining. Result: Compared with Sham operation group, I/R group showed significant increases in neurologic deficit scores and the level of NSE in serum, and improved cerebral histopathology injury (P<0.01), notable decreases in positive area and integral absorbance (IA) in cortex and hippocampus CA1 area at the damage side, but only statistical differences between brain cortex and Sham operation group; Compared with I/R group, CIP+MCAO decreased the neurologic deficit scores (P<0.05), cerebral histopathology injury (P<0.05), and NSE in serum (P<0.01). At the same time, the positive area and integral absorbance (IA) of BDNF, VEGF in cortex, and CA1 area at the damage side increased obviously (P<0.01, P<0.05). The positive expression of GDNF showed an increasing trend, but with no statistical difference. Conclusion: The neuroprotective effects of CIP were correlated with the up-regulation of the endogenous proteins BDNF and VEGF.  
摘要:Objective: To observe the effect of catalpol on oxidized low density lipoprotein(ox-LDL) induced inflammatory cytokine in EA.hy926 cells and to explore its possible mechanism from the prospective of nuclear factor-κB(NF-κB) activation. Method: Humane endothelial cell line EA.hy926 was cultured and randomly divided into blank group, catalpol group(0.5 mmol·L-1), ox-LDL group(100 mg·L-1), catalpol high-dose group(0.5 mmol·L-1), and low-dose group(0.05 mmol·L-1). The mRNA and protein expression levels of tumor necrosis factor α(TNF-α) and vascuolar cell adhesion molecule-1(VCAM-1) in EA.hy926 cells were detected by RT-PCR and Western blot respectively. Viability and apoptosis ratio of EA.hy926 cells were detected by MTT and Hoechst staining respectively. NF-κB activation was detected by Western blot and ELISA. Result: As compared with the blank group, EA.hy926 cells were injured very slightly in catalpol protection group, and the mRNA and protein expression levels of TNF-α and VCAM-1 were significantly reduced and NF-κB activation was inhibited in a dose-dependent manner(P<0.05). Therefore, catalpol can effectively reduce ox-LDL-induced inflammatory response in EA.hy926 cells, which may be related to inhibition of NF-κB activation.

摘要:Paris polyphylla var. chinensis, as an important source of Paridis Rhizoma in Chinese Pharmacopoeia, has many pharmacological efficacies, such as clearing heat and toxic matter, relieving swelling and pain, cooling the liver and relieving convulsion, and been clinically used for anti-tumor, antibiosis, hemostasis, analgesia and so on. P. polyphylla var. chinensis, as a perennial plant, has a low reproductive rate and long growth period, with seven years from seed germination to medical application. Recently, its wild plant resources became rare because of the excessive excavation, which cannot meet the need of the market, caused a high market price, and even posed a serious threat to the survival and sustainable use of its resources. To solve this problem, developing artificial breeding technology and breeding the cultivated species are the best way to protect the wild plant resources and meet the clinical demands. Literature related to the breeding technology of P. polyphylla var. chinensis were retrieved and summarized to make a review about seed collection and seedling, so as to provide the theoretical guidance for the artificial breeding. Meanwhile, the breeding quality was discussed based on the correlative chemical composition during the growth of the seedlings. The breeding technology of P. polyphylla var. chinensis is the first important step to breed good-quality varieties, while the detection for the subsequent quality is significant as well. In this article, the quality evaluation system was established for wild and bred varieties in a multi-disciplinary and multi-angle manner, in order to guarantee the quality of Chinese medicinal materials, and provide a reference for further exploitation and utilization of P. polyphylla var. chinensis.
