The model group were given dinitrobenzene sulfonate （DNBS）/ethanol solution enema+hydrocortisone subcutaneously injection+senna leaf gavage to establish UC model of spleen kidney yang deficiency. The rats who successfully established the model were randomly divided into five groups：model group， mesalazine （0.36 g·kg-1） group， and Sishenwan high， medium and low dose （3.2，1.6，0.8 g·kg-1） groups， the volume of which was 10 mL·kg-1. The model group and the blank group were given distilled water of the same volume. Once a day for 21 days. Observe the general conditions of the rats daily， and record the weight， fecal traits and occult blood of the mice for disease activity index （DAI） scoring.Take the rat colon tissue to observe the gross morphology and colon injury， and score the colon mucosal injury index （CMDI）. Hematoxylin-eosin （HE） staining was used to observe pathological changes. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）was used to detect the expression level of PI3K， Akt， mTOR mRNA in colon tissue. The levels of IL-1β and IL-10 in serum were detected by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the expression level of PI3K， phosphorylation （p）-PI3K， Akt， p-Akt， mTOR， p-mTOR protein in colon tissue.ResultCompared with blank group， the general survival status of the rats in model group was relatively poor， the DAI score and the CMDI index were significantly increased （P<0.01）. The intestinal mucosa partially disappears， the glands disappear， and a large number of inflammatory cells infiltrate and gather in the mucosal layer and the base layer in the pathological sections of the model group. The expression levels of PI3K， Akt， and mTOR mRNA were significantly increased （P<0.01）. The IL-1β content was significantly increased and the IL-10 content was significantly decreased （P<0.01）. The expression levels of p-PI3K，p-Akt and p-mTOR protein were significantly increased （P<0.01）. Compared with the model group， the DAI scores of Sishenwan high and medium dose groups and mesalazine group decreased （P<0.05）. The CMDI index of mesalazine group and the high， middle and low dose groups of Sishenwan was significantly reduced （P<0.01）. Pathological sections of rats showed that the inflammatory cells in the drug group decreased， and the mucosal layer structure returned to normal to varying degrees. The mesalazine group and the Sishenwan medium-dose group had the best effects， and the mucosal structure was close to the blank control group. The expression levels of PI3K， Akt， mTOR mRNA in the high and medium dose groups of Sishenwan， mesalazine group and Akt mRNA in low dose group of Sishenwan were significantly reduced （P<0.05，P<0.01）. The expression levels of PI3K and mTOR mRNA in low-dose group of Sishenwan decreased， but the difference was not statistically significant. The IL-1β content was significantly reduced and the IL-10 content was significantly increased in high， medium dose groups of Sishenwan and mesalazine groups （P<0.05，P<0.01）. The level of IL-1β decreased and the level of IL-10 increased in the low-dose group of Sishenwan， but the difference was not statistically significant. The expression levels of p-PI3K， p-Akt and p-mTOR protein in the high， medium， and low dose groups of Sishenwan and mesalazine group decreased to varying degrees， and the differences were statistically significant（P<0.05，P<0.01）.ConclusionSishenwan has the effect of improving the general condition and intestinal mucosal damage of ulcerative colitis model rats with spleen and kidney Yang deficiency. The mechanism may be related to the inhibition of PI3K/Akt/mTOR signaling pathway.

The analysis of the expression of the data. Furthermore， three commonly used internal reference gene analysis software，namely geNorm，NormFinder and BestKeeper，was used to analyze and evaluate the stability of the candidate internal reference gene.ResultThe internal five reference genes were expressed in the bark，branches and leaves of the two plants，but with differences in stability. Comprehensive analysis showed that the expression stability of candidate internal reference genes was in the order of GAPDH>actin>UBE>histone>TUB. The internal reference genes of the two plants were analyzed separately，and the optimal internal reference gene was still GAPDH，indicating that GAPDH was the most suitable internal reference gene. TUB and histone ranked low in the three software，and should be eliminated in the screening of reference genes. They were not suitable for gene expression analysis of C. cassia and C. cassia var. macrophyllum.ConclusionThe most suitable internal reference gene for different parts of cinnamon，branches，and leaves of C. cassia and C. cassia var. macrophyllum was GAPDH. In this study，a screening system for internal reference genes of Real-time PCR of C. cassia and C. cassia var. macrophyllum was established to provide theoretical basis for studying functional regulation and expression of genes during the accumulation of effective components in different parts.

Abstract：Xiebaisan is one of the 100 classical prescriptions published by the state， and the research and development of its compound preparation has gradually become an upsurge. The research and development of classical prescriptions should start from the theory of traditional Chinese medicine and clinical practice， laying a solid foundation for research and development. Based on the above thinking， this study adopts the methods of traceability and bibliometrics to analyze the source， pathogenesis， efficacy， Fangyi and clinical application of Xiebaisan in order to further promote its literature research work. The results show that the origin of Xiebaisan can be traced back to the prescription of Xiefeitang in Yinhai Jingwei（Volume 1）. Although there are more than 20 prescriptions with the same name of Xiebaisan developed in later generations， they either reflect the inheritance and development of Qian Yi's thought of composing prescriptions， or only the meaning of "Xiebai" in the name of the prescription. The main pathogenesis of Xiebaisan is adverse lung Qi of heat. Mori Cortex and Lycii Cortex are sweet and cold， which can clear away lung heat and reduce adverse Qi， and then cough and asthma can stop. Supplemented with Glycyrrhizae Radix et Rhizoma and japonica rice， which are endowed with the meaning of nourishing earth and generating gold， to invigorate spleen and replenish Qi. The compatibility of Xiebaisan can clear away lung heat， relieve cough and asthma， and norish erath and generate gold to treat lung heat， asthma and cough. Although the main treatment of Xiebaisan recorded in ancient books involves various diseases and syndromes of internal， external， gynecology and pediatrics， the pathogenesis of Xiebaisan is "adverse lung Qi of heat". Modern clinical application of Xiebaisan focuses on the respiratory system， skin and subcutaneous tissue system， ear， nose and throat system， digestive system， ophthalmic system， etc.， and it has more advantages in the treatment of pneumonia， cough， bronchitis， epistaxis， acne， bronchiectasis， postinfectious cough， constipation and other diseases. The syndrome differentiation of the above diseases is in accordance with the relevant syndrome types with lung heat as the main pathological factor， so we can modify and apply the prescription appropriately.
Abstract：Tumors are new organisms formed by uncontrollable cell proliferation of local tissues driven by various oncogenic factors. The cause of tumors is unknown with life-threating outcome. Tumors can be classified into benign tumors， borderline tumors， and malignant tumors according to their pathological properties. Among them， malignant tumor is commonly known as cancer， with no specific medicines or reliable cure means， so this is a hot spot and difficult point in current medical research. In ancient literatures， there are many records about the efficacy of Chinese herbal medicine in treating tumor， and modern pharmacological researches have shown that more and more active ingredients of traditional Chinese medicine（TCM） have gradually highlighted their inhibitory effect on various types of tumor. Caulis sinomenii has been used for treatment of rheumatic diseases in TCM for a long history. Sinomenine is a major bioactive alkaloid presented in C. sinomenii， which has demonstrated a wide range of pharmacological activities such as anti-inflammation， immunosuppression， analgesia and sedation， and due to its slightly soluble in water， it is commonly used in clinic in the form of hydrochloride， with its commercial name of Zhengqing Fengtongning. Recent studies show that sinomenine alone or combined with chemoradiotherapy can inhibit growth of several tumors significantly or in a synergistic way， so it is termed as an inhibitor of tumors. Anti-tumor effect of sinomenine involve inhibition of tumor cell proliferation， induction of tumor cell apoptosis， blockade of tumor cell cycle， suppression of tumor invasion and metastasis， induction of autophagy of tumor cells， and reversal of multidrug resistance of tumor cells. Upon combination with nanomaterials， it can enhance efficiency and reduce toxicity. Here we summarized and reviewed recent advances on basic anti-tumor research of sinomenine， and then made a classification and description according to its in vivo and in vitro pharmacological action and mechanism of action， so as to elucidate the great potential of sinomenine as a promising anti-tumor drug， and provide reference for further research on its anti-tumor mechanism.

Abstract：Asari Radix et Rhizoma （ARR） is a traditional Chinese medicine for relieving exterior syndrome， and its roots and stems contain rich chemical components， including volatile oils （terpenoids， aromatics and aliphatics）， lignans， flavonoids， etc. Clinically， it has been traditionally used for the treatment of diseases such as phlegm and cough， anemofrigid cold， rheumatic arthralgia due to its ability to spread cold. Modern pharmacological studies have shown that ARR played beneficial roles in analgesic， anti-inflammatory， antitussive， antiasthmatic， antiviral， antibacterial， sedative， antioxidative， and antidepressant responses， antihypertension， as well as tumor suppression. The current studies on the chemical composition of ARR mainly focused on volatile components， and little information is available for the occurrence and pharmacological effects of non-volatile components. In addition， there is a lack of clear classification of chemical components and the distribution of chemical components in medicinal parts and the origin of species. Therefore， in this study， the authors reviewed a large number of literature on the chemical compositions and pharmacological effects of ARR， and hoping to provide a reference for further pharmacological research and the new drug development of ARR.

Abstract：The global incidence of breast cancer has increased year by year. Breast cancer has the highest mortality rate in female patients with malignant tumors. Traditional Chinese medicine（TCM） has made great contribution to health of human being， improving the overall curative effect， reducing the patients' pain， improving the quality of life and alleviating adverse reactions in patients. TCM and its active compounds can inhibit the proliferation of breast cancer cells by inducing cell cycle arrest， invasion， metastasis and reversing multidrug resistance. The effect of the compounds in TCM is obvious on inducing the arrest of the breast cancer cells cycle. It′s a novel method to fight against breast cancer by influencing the progress of the breast cancer cell cycle and inducing the cell cycle arrest in breast cancer cells. Lots of studies have shown that the G2/M phase checkpoint which transition from gap-phase （G2 phase） to mitotic phase （M phase） in the cell cycle is the key point for cell survival or death. Many antitumor drugs can inhibit the proliferation of tumor cells through the cell cycle arrest. We summarized the domestic and foreign literatures in recent years， and comprehensively explained the research progress on the related regulatory molecules in G2/M arrest. In addition， we summarized and sorted out the researches on the methods and ways of alkaloids， polysaccharides， terpenes， flavonoids， saponins and other active compounds of TCM in inducing the G2/M arrest of human breast cancer cells. By summarizing the active compounds of various Chinese medicines in inducing G2/M arrest of breast cancer cells， and reviewing the research progress on mechanism of active TCM compounds for inhibiting the proliferation of breast cancer cells， we will， in this paper， investigate the mechanism of active TCM compounds for inhibiting the proliferation of breast cancer cells through inducing G2/M arrest of human breast cancer cells， so as to provide a scientific basis for in-depth research on the anti-breast cancer mechanism of the active compounds in TCM.
Abstract：Intestinal Peyer's patches （PPs） are local immune tissues of the intestine， which are considered to be the main induction site of the intestinal mucosal immune response， and closely related to immune-related refractory enteropathies， such as ulcerative colitis and Crohn's disease. In recent years， more and more scholars have tried to find a new breakthrough for treating refractory enteropathies with a limited efficacy of clinical interventions through in-depth study of the relationship between PPs and enteropathy. Traditional Chinese medicine （TCM） polysaccharides are considered to be a key component for immune regulation with TCM. Modern studies show that TCM polysaccharides have a significant positive intervention effect on the structure and function of PPs， with good development prospects. Based on this， this paper focuses on PPs and intestinal-related diseases， and systematically introduces the physiological structure of PPs and their drug delivery mechanism， and summarizes the interactions of PPs with effect on immune-related enteropathies， analyze of current studies and prospects of effect of TCM polysaccharides in intervening intestinal disease and its dysfunction by regulating PPs， with the aim to provide new strategies for basic studies and clinical treatment of immune-related refractory enteropathies from the perspective of PPs， and new ideas for basic studies and clinical studies on effect of TCM polysaccharides in intervening enteropathies.

Abstract：Adequate sleep is an important factor to ensure the healthy functioning of the body. A type of chronic sleep diseases characterized by insufficient sleep can be collectively referred to as sleep deprivation （SD）， which is divided into primary and secondary sources in terms of sources. As one of the most frequent types of diseases in recent years， SD has received more and more attention and attention from the whole society. SD can have a wide-ranging and far-reaching impact on cognitive behavior， such as decreased wakefulness， decreased alertness， and inattention， decreased sensory perception， decreased learning and memory capabilities， et al， involving the impact on multiple system functions of the human body， and It is closely related to the occurrence of many diseases， and may cause serious troubles to the normal life of patients and even their relatives and friends. The cognitive impairment caused by SD has been fully verified in clinical tests and various animal behavior experiments， mainly involving pathological damage such as changes in synaptic plasticity， enhanced endoplasmic reticulum stress， circadian rhythm disorders， and energy metabolism imbalance. Western medicine treatments for SD mostly have negative factors such as high side effect and strong addiction. However， Chinese medicine intervention focuses on the overall concept， has long-lasting effectiveness， significant effects， and mild side effects. It has also been widely recognized clinically for improving the complications of sleep disorders. This article reviews the current status and classification of SD research， its pathological mechanisms that lead to cognitive impairment and its molecular-level exploration directions and results. In recent 5 years， the therapeutic effect and experience of traditional Chinese medicine intervention therapy such as compound Chinese medicine， acupuncture and moxibustion as well as auxiliary therapy such as exercise and five sounds， in order to further summarize and clarify the interaction mechanism between SD and cognitive behavior， and provide a theoretical basis for the study of the pathological mechanism of SD disease and future clinical treatment.

Abstract：Gastric cancer is one of the most common malignant tumors in the digestive system， and precancerous lesion of gastric cancer （PLGC） represents a long-term stage in the process of malignant development of normal gastric mucosa into gastric cancer. Gastric cancer and precancerous lesions are difficult to cure clinically， leaving poor prognosis and a serious negative impact on the quality of daily life of patients. In recent years， studies on cell autophagy have been at the forefront of the natural life science. Regulating autophagy to treat precancerous lesions and prevent gastric cancer has become nowadays a hot topic. Autophagy is a process in which cells enclose some redundant or damaged cytoplasm， proteins and organelles to form autophagosomes， and bind to lysosomes to degrade the contents. Autophagy has bidirectional effect on different cells and different stages of the same cell. Autophagy at a lower level can kill cancer cells， while autophagy can promote the growth and proliferation of cancer cells under stress conditions such as hypoxia， hunger and infection， or when autophagy clears damaged proteins in cells and organelle function is abnormal. Traditional Chinese medicine（TCM）， which has low toxicity and easy acceptance by patients， has a positive effect on the treatment of gastric cancer and PLGC. At present， studies on the prevention and treatment of gastric cancer and PLGC by TCM have been carried out in depth with cell autophagy as the breakthrough point. More and more research results have confirmed that TCM can regulate the autophagy process of gastric cancer cells and play an anti-tumor role by interfering with various autophagy related genes， signal pathways and organelles. This paper summarizes the studies on the regulation of cell autophagy by TCM in the treatment of gastric cancer and precancerous lesions， so as to provide references for future studies on the regulation of autophagy by TCM.

Abstract：Periplaneta americana is one of the important basic medicinal materials of traditional Chinese medicine "fei lian". The traditional functions mainly include promoting blood circulation， sore muscles， diuresis， spleen and phlegm. Because of its exact curative effect， proprietary Chinese medicines， which are mainly used as raw materials， are widely used in clinical practice， especially in the repair of various wounds. The drug has not been included in the Chinese Pharmacopoeia. The local standard is only based on the alanine content of total amino acids. The physiologically active small peptides， nucleosides， proteins and other substances have not been obtained. Qualitative or quantitative control. In recent years， peptide monomers isolated from the P.americana， such as antimicrobial peptides， neuropeptides， and diuretic peptides， have strong pharmacological activities such as antibacterial， antitumor， and muscular neurotrophic， and dihydroisocoumarins are also irritating. Dermal Dermal fibroblasts produce collagen. Based on this， this paper uses CNKI， Wanfang Database and Pubmed Database to search the relevant research literatures of P.americana from 1984 to 2019， and systematically analyzes the current research of P.americana from three aspects： chemical composition-pharmacological action-clinical application. Interpretation provides reference for the further development of the drug and the development of more specific and stable quality control standards for its proprietary Chinese medicines.

Abstract：Succus Bambusae， regarded as the holy medicine for the treatment of phlegm by traditional Chinese medicine experts， has the functions of clearing heat and resolving phlegm， resuscitating and relieving convulsions. In clinical practice， it is mainly used to treat phlegm-heat cough， phlegm yellow and shortness of breath， stroke with exuberant phlegm and other syndromes. The research of its processing procedure and quality standard is the key issue to realize the process modernization and quality standardization of this traditional medicine resource. On the basis of literature research， this paper conducted the herbal textual research on Succus Bambusae， sorted out its medicinal history， and compared the advantages and disadvantages of its traditional and modern preparation procedure. Based on the historical records， it is pointed out that there are still many problems in the traditional and modern processing procedure of Succus Bambusae， such as low-yield processing procedure and extensive production technology that cannot meet the requirements of large-scale green manufacturing. At present， there are a lot of literature on the comparative study of the origin， variety and processing procedure of Succus Bambusae， but most of them are limited to the chemical components， and lack of in-depth study on its pharmacodynamic substance basis and mechanism. Meanwhile， the pharmacological effects of Succus Bambusae are mostly limited to antitussive and expectorant， and few other pharmacological effects have been reported. Based on the above analysis， it is suggested that the follow-up research work can be carried out from these five aspects：①Clarifying the original source， enriching and perfecting the medicinal resources. ②Standardizing the processing procedure， establishing relevant quality standards. ③Clarifying the pharmacological mechanism， strengthening the basic research on the pharmacological effect and clinical application. ④Inheriting ancient processing， researching and developing special preparation equipment and standardizing production operation rules. ⑤Comprehensive utilization of the by-products in preparation process.
