To analyze the composition regularity of prescriptions containing Scutellaria baicalensis in Drug Standard of Ministry of Public Health of the Peoples Republic of China--Chinese Patent Medicines and Preparations on the basis of the traditional Chinese medicine inheritance support system (TCMISS), in order to provide reference for new drug R&D. the platform's software V2.0 was applied to establish a database of prescriptions containing S. baicalensis. The software's statistical statement module, association rules and improved mutual information method and other data mining technologies were adopted to analyze commonly used drugs, combination rules and core combination of S. baicalensis prescriptions. Having analyzed 477 prescriptions containing S. baicalensis, the researchers summarized 45 most commonly used drug combinations, whose ingredients mostly had functions of heat-clearing and damp-drying, purging fire for removing toxin and hemostasis. Drugs adopted in core combinations were relatively concentrated and selected according to definite composition methods. There were 23 diseases that S. baicalensis were most frequently applied in the treatment. Having compared three highly frequent diseases--cold, cough and dizziness, the researchers concluded that S. baicalensis could show different therapeutic effects through different combination ratios. Therefore, TCMISS (V2.0) is an important tool in analyzing the composition regularity of traditional Chinese medicines. The longitudinal and parallel comparison method is an effective method for studying the clinical composition regularity of S. baicalensis, while providing reference for new drug R&D.

OBJECTIVETo evaluate the safety and long-term effect of recombinant human epithelial growth factor (rhEGF) on deep partial-thickness burn wounds.

METHODSThirty-seven burn patients were enrolled in this study and were observed by randomized, double-blinded and placebo-controlled protocol. An area of deep partial-thickness burn wounds from each patient was divided into control (C) and treatment (T) portions. The wound in C was treated with normal saline while that in T with rhEGF. The patients were followed-up for 1 and 4 years after wound healing. The healed wounds were evaluated by modified Vancouver scar scale in terms of scar index (SI).

RESULTS1 year after wound healing, it was found that the SI in T group (7.19 +/- 1.67) was obviously lower than that in C group (8.92 +/- 1.78, P < 0.01). The SI in T group (6.12 +/- 1.54) was still evidently lower than that in C group (8.09 +/- 1.81, P < 0.01) four years after wound healing. There were no signs of development of tumor or cancer in all the tested burn wound areas.

CONCLUSIONExternal application of rhEGF might be beneficial to the healing quality of deep partial-thickness burn wound with less scar formation and better long-term effects, and it is safe.

OBJECTIVE: To investigate the relationship between the expression of Ang2, Tie2 and the angiogenesis of hepatocellular carcinoma in rats. METHODS: Thirty-eight healthy male rats were randomly divided into 3 groups: 5 rats in the control group; 25 rats in the experimental group were equally divided into 5-day, 10-day, 15-day, 20-day, and 25-day groups; the other 8 rats were used as the supplement of the experimental group. An allogenic transplanted rat model of CBRH-7919 hepatocellular carcinoma in situ was established by immunosuppression. The expressions of Ang2 and Tie2 were detected by immunohistochemical staining in cancerous tissues of different developmental stages and liver tissues of the control group. At the same time, microvessel density was determined by anti-CD31 immunohistochemical staining. RESULTS: CBRH-7919 hepatocellular carcinoma models were successfully set up in 24 rats. The expression level of Ang2 and Tie2 in cancerous tissues was much higher than that of liver tissues of the control group (P <0.05). The overexpression of Ang2 was pristine and continuous in different developmental stages. The expressions of Ang2 and Tie2 positively correlated with microvessal density in hepatocellular carcinoma (P<0.05). CONCLUSION The up-regulation of Ang2 and Tie2 may play important roles in the angiogenesis of hepatocellular carcinoma. Ang2 may participate in the start of angiogenesis of hepatocellular carcinoma.

The traditional Chinese medicine prescription Yueju Wan has the function of regulating qi-flowing for activating stagnancy and resolving food stagnation, which is now used for the treatment of depression and gastrointestinal related diseases. In this study, an integrative pharmacological method was adopted to predict the targets and pathways of Yueju Wan and explore its molecular mechanism for depression and gastrointestinal dysfunction with the same treatment. First, disease targets were collected from Human Phenotype Ontology database, 201 targets related to depression and 474 targets related to gastrointestinal dysfunction, including 95 common targets of these two. Then, the integrative pharmacology platform of traditional Chinese medicine (TCMIP) was used to predict and analyze the drug targets, GO function, KEGG pathway, core targets network of Yueju Wan and heterogeneous network of TCM-chemical components-key drug targets-pathway. According to the integrative analysis, it is found that ATP1A1, KRAS, and PRKAA1 were key targets, and neuron apoptotic process, neurotrophin signaling pathway, serotonergic synapse and regulation of nitric-oxide synthase activity were key pathways which played important roles in molecular mechanism of Yueju Wan for depression and gastrointestinal dysfunction. In conclusion, speculated serotonergic synapse and regulation of nitric-oxide synthase activity maybe the common process in depression and gastrointestinal dysfunction. This paper provided an overall understanding on Yueju Wan based on TCMIP, helping to elucidate the mechanism of the same treatment for different diseases, depression and gastrointestinal dysfunction.

By using the traditional Chinese medicine inheritance support system (TCMISS) in this study, the prescription rules of Baizhi formulae were analyzed and the core herbal pair "Baizhi-Chuanxiong" was obtained. Through the systemic analysis of prescription rules of "Baizhi-Chuanxiong" and combined with the pharmacology thinking of "Baizhi-Chuanxiong" in treating headache, the paper was aimed to find out the combination rules containing Baizhi andits molecular mechanisms for treating headaches, and provide the theory basis for further research and reference of Baizhi and its formula. Totally 3 887 prescriptions were included in this study, involving 2 534 Chinese herbs. With a support degree of 20% in analysis, 16 most commonly used drug combinations were screened, which were mainly used to treat 15 types of diseases. Baizhi was often used to treat headache, and the core combination "Baizhi-Chuanxiong" was also often used to treat, consistent with ancient record. A chemical database was established; then the headache and migraine disease targets were retrieved and added in the database to build up the "compounds-targets-pathways "core network of "Baizhi-Chuanxiong" by the internet-based computation platform for IP of TCM (TCM-IP). TCM-IP was then applied to study the molecular mechanism of "Baizhi-Chuanxiong" treatment of headache. The results suggested that37 chemical compounds in the core combination "Baizhi-Chuanxiong" were closely related with headache treatment by adjusting serotonin levels or applying to inflammation-related targets and energy metabolism pathways such as purine metabolism, pyruvate metabolism, fatty acid degradation, carbon metabolism and gluconeogenesis.
