Endocannabinoids are endogenous brain ligands of cannabinoid receptors and have specific synthesizing,transporting,metabolizing ways in the body. Endocannabinoids can regulate release of some neurotransmitters such as glutamate or GABA. So elucidating the mechanism of endocannabinoids is not only helpful in understanding the mechanisms of cannabiod addicton but also useful in developing new useful drugs.

During the last forty years, although cytotoxic chemotherapy for gastric cancer patients has improved to some extent, its therapeutic effect is limited. Simultaneously, great progression of oncobiology to increase our understanding of the molecular basis of gastric cancer has been made. Currently the cancer cell has been characterized by several genetic changes that lead to altered cellular functions. In addition, multiple cancer-cell environment factors affect the tumor cell via various receptors and subsequent signaling pathways. The increasing knowledge of cellular signaling offers the opportunity to develop novel substances that target specific pathway molecules.

OBJECTIVE: To analyze and evaluate the quantitative evaluation of ADR signals in FDA and to provide a reference for ADR evaluation in China. METHODS: By means of literature review,contrasting analysis and data reduction,ADR signal evaluation in FDA was investigated. RESULTS&CONCLUSION: In USA MGPS method is used for the quantitative evaluation of ADR signal, which can earlier obtain ADR signal and effectively promote the risk warning ability of ADR information. This is practical in our country and we should learn from them. Combined with various data analyzing methods, we can set up a high-quality evaluation database for ADR signals. The importance of pharmacoepidemiology and statistics in ADR evaluation should be highly recognized and the methods for ADR signals evaluation should be gradually shifted from qualitative to quantitative evaluation.

OBJECTIVE:To provide reference for ADR evaluation in China.METHODS:The ADR signal evaluation method adopted by the pharmacovigilance center in Netherlands was analyzed by means of literature review,contrasting analysis and data reduction etc.RESULTS & CONCLUSION:We should draw experience from the pharmacovigilance center in Netherlands about the evaluation method on ADR signal and establish ADR evaluation databases of high quality;furthermore, we should attach great importance to the application of pharmacoepidemiology and statistics in ADR evaluation and gradually replace the qualitative evaluation with quantitative one for ADR signal.

AIM: To investigate the effects of Tangmoning (TMN) Granule on nerve conduction velocity, red blood cell sorbitol (RBC S) level in diabetic rats and probe the mechanism of prevention and treatment of diabetic peripheral neuropathy. METHODS: The model of diabetic rat was induced by strepotozotocin. The animals were randomly divided into six groups:TMN minimal dose group, TMN mild moderate dose group, TMN maximal dose group, methycobal group, model group and normal control group. All TMN groups were treated with TMN Granule through tube feeding (2.95 g/kg、5.90g/kg、11.80g/kg). Methycobal group was treated with methycobal tablets through tube feeding (0.14mg/kg). The duration of treatment was 3 weeks. The caudal nerve conduction velocity, RBC S content were investigated before and after treatment. RESULTS: It showed that TMN Granule could increase the caudal nerve conduction velocity significantly in the maximal dose group and the mild moderate dose gorup ( P

Objective To observe the effect of hot spring medicated bath regimen which is guided by the theory of constitution distinction of TCM.Methods According to the standard of Constitution Classification and Decision of TCM which is published by China Association of Chinese Medicine to assess the standard-compliant volunteers,then make the volunteers have physical-chemical indexes checked and hot spring medicated bath taken.At last,re-assess the constitution of the individual and re-check the indexes.Results After the drug bath,the levels of total cholesterol (TCH),low-density lipoprotein (LDL-C),thyroid stimulating factor(TSH),and IL-1 of the patients who were both yang deficiency and phlegm-dampness decreased significantly (t values were 2.093,2.045,2.092,and 2.13,respectively; P＜0.05); the levels of high-density lipoprotein (HDL-C),cortisol,and free thyroxine T4 (fT4) increased significantly (t values were 3.731,2.571,and 3.027,respectively; P＜0.05) ; the pulse rate raised obviously (t=8.323,P＜0.01) ; both of the systolic (t=4.405,P＜0.01) and diastolic (t=2.782,P＜0.01)blood pressure dropped.After the drug bath,the levels of fT4 and IL-1 of the patients who were yang deficiency significantly increased (t values were 3.709 and 3.339,respectively; P＜0.01); the waist circumference reduced (t=2.831,P＜0.01),the pulse rate rised (t=9.605,P＜0.01) ; both of the systolic (t=5.281,P＜0.01)and diastolic (t=6.573,P＜0.01)blood pressure dropped.After the drug bath,the levels of pulse rate and diastolic blood pressure of the patients who are phlegm-dampness changed significantly:the pulse rate raised (t=4.702,P＜0.01),the diastolic blood pressure dropped(t=6.096,P＜ 0.01).As the effect analysis showed,the Ridit data of the criterion group which consists of summation was 0.5.Compared with the criterion group,the total effective rate of the yang deficiency group was 74.1％,which was statistically significant (R=0.55,P＜0.05).The total effective rate of the phiegm-dampness group was 81.8％,which had no statistical significance (R=0.48,P＞0.05).The total effective rate of the both yang deficiency and phlegm-dampness group was 77.4％,which was statistically significant (R=0.46,P＜0.05).Conclusion The Wuyi hot spring medicated bath regiman is helpful to the constitution type of yang deficient and phlegm-dampness,which can help warming yang and benefiting qi,living blood links contact us nourishing the skin,reducing blood fat,lowering blood pressure,improving the immune function and so on.
