AIM: To develop a method for determining contents of ginsenoside Rb_1,ginsenoside Rg_1 and notoginsenoside R_1 in Sanxue Mingmu Tablet(Radix et Rhizoma Notoginseng,Pheretima,Herba Leonuri,Rhizoma Imperatae,etc.). METHODS: The contents of ginsenoside Rb_1,ginsenoside Rg_1 and notoginsenoside R_1 were separated by gradient elution on Hypersil ODS C_(18) column(5 ?m ? 4.6 mm?100 mm) as stationary phase;acetonitrile and water as gradient mixed mobile phase;detected at 203 nm wavelength;(25 ?C) of column temperature and 1.0 mL/min of mobile rate. RESULTS: Ginsenoside Rb_1,ginsenoside Rg_1 and notoginsenoside R_1 had good linearities(r=0.999 9;n=6) at the ranges of 1.480 0-14.800 ng;0.372 0-3.720 ng and 1.072 0-10.720 ng.The average recoveries were 98.44%(RSD=0.96%);99.02%(RSD=0.94%);97.95%(RSD=(1.02%)),respectively. CONCLUSION: This method is high in column efficiency and satisfactory for isolation and repeatability,the result is accurate.It can be adopted for quality control of Sanxue Mingmu Tablet.

Objective To analyze the relationship between traditional & emerging risk factors and the pathogenesis of atherosclerotic renal artery stenosis (ARAS) in different gender patients.Methods Selective renal artery angiography was performed immediately after routine coronary angiography in 2060 patients with suspected coronary artery disease.Traditional & emerging risk factors were recorded and compared in different gender patients with ARAS.Results Among the patients with ARAS, smoking (59.18％ vs.12.50％, x2 =17.47,P＜0.01) and diabetes(28.57％ vs 46.87％, x2 =5.64, P＜0.05) compared with both genders were significantly differences.There were significant differences in high density lipoprotein cholesterol, ApoA1, ApoB/ApoA 1, HbA1C and Hcy (t =2.62,2.07,-2.83,-2.37,3.74;P＜ 0.05) in the ARAS patients compared with both genders.Conclusion The main risk factors in different gender patients with ARAS were different.It is important to adopt appropriate control strategies.

Treatment by way of pasting TCM on acupoints has a long history and the clinical efficacy is determined. In this article, based on the concept of TCM wholism and meridian theory, the mechanism of acupoint pasting therapy was expounded from the aspects of medicine effects on local stimulation of the body, meridian conduction, medicine transdermal absorption. Combining with the research hot spots of modern medicine transdermal delivery system, metabolomics, and efficacy material, this article proposed a new study mode of systems biology of TCM.

At present, TCM treatment of diarrhea-predominant irritable bowel syndrome (IBS-D) is based on the combination of disease differentiation and syndrome differentiation. Therefore, the establishment of IBS-D of liver stagnation and spleen deficiency syndrome combined with animal model as a combination of traditional Chinese and Western medicine innovation theory has become increasingly concerned about, and gradually become a new direction for the development of TCM experimental animal model. This article reviewed the research progress in IBS-D liver and spleen deficiency syndrome in recent years, discussed the establishment of IBS-D liver stagnation and spleen deficiency animal model and research ideas for the treatment of IBS-D, and provided references for mechanism research of TCM treatment for IBS-D and research and development of new medicine.

Objective To observe the protective effect of modified Baishile Decoction on hippocampal neuronal cells cultured in vitro;To explore its mechanism of treating post-stroke depression.Methods Hippocampal neuronal cells from mammary rats were isolated and cultured in vitro,cell injury was induced by oxygen glucose deprivation combined with lipopolysaccharide.The cells were divided into normal group,model group,blank serum group(10%)and modified Baishile Decoction containing serum group(10%).Invertedmicroscope was used to observe cell morphological changes,CCK-8 method was used to detect cell survival rate,Hoechst33342 staining was used to observe apoptosis,ELISA was used to detect Glu,5-HT,TNF-α,IL-1β,and IL-6 contents in cell supernatant,the expressions of purinergic P2X7 receptor(P2X7R)and NOD-like receptor protein 3(NLRP3)were detected by immunofluorescence staining.Results Compared with the normal group,the hippocampal neurons in the model group showed significant changes in cell morphology,the cell survival rate significantly decreased(P<0.01),the cell apoptosis increased(P<0.01);Glu,TNF-α,IL-1β,IL-6 contents in cell supernatant significantly increased(P<0.05,P<0.01),5-HT content significantly decreased(P<0.01),P2X7R and NLRP3 expressions in hippocampal neuronal cells significantly increased(P<0.01).Compared with the model group,the morphology of hippocampal neurons in modified Baishile Decoction containing serum group was significantly improved,the cell survival rate significantly increased(P<0.01),the cell apoptosis reduced(P<0.01);Glu,TNF-α and IL-1β content in cell supernatant significantly reduced(P<0.05,P<0.01),5-HT content significantly increased(P<0.01),and P2X7R and NLRP3 expressions in hippocampal neuronal cells significantly decreased(P<0.01).Conclusion Modified Baishile Decoction may exert a protective effect on oxidative glucose deprivation combined with lipopolysaccharide induced hippocampal neuronal inflammation damage by inhibiting the P2X7R/NLRP3 signaling pathway,regulating neurotransmitter secretion,and inhibiting inflammatory factor release,thus treating post-stroke depression.

OBJECTIVE： To provide scientific evidence for establishing perfect rationality evaluation indicator system of antibiotics. METHODS： On the basis of literature research， Delphi method was used to conduct several rounds of consultations on 30 experts in related fields with E-mail and questionnaire field investigation. After several rounds of consultations， rationality evaluation index system for antibiotics was determined. The effective recovery rate of expert consultation questionnaire was used to express the positive coefficient of experts； the authoritative coefficient was used to express the authoritative degree of experts； the index importance assignment and the full score ratio were used to reflect the concentration degree of experts’ opinions； the coefficient of variation and the coefficient of coordination were used to express the coordination degree of experts’ opinions. RESULTS & CONCLUSIONS： After two rounds of consultations， response rates of the questionnaire in two rounds of surveys were 100％ and 96.67％， indicating experts were highly motivated. The authoritative coefficients were 0.91 and 0.88， indicating experts had a high degree of authority. Finally， an evaluation index system for rationality of antibiotics was established， which included four first-level indicators （indications， drug selection， medication process， management indicators） and 35 second-level indicators. Among them， the mean value of importance scoring of first-level indicators ranged from 4.28 to 5.00， the full score ratio from 0.93 to 1.00， the coefficient of variation from 0.00 to 0.15 and the coefficient of coordination was 0.446 （P＜0.001）. While， the mean value of importance scoring of second-level indicators ranged from 3.83 to 4.79； the full score ratio from 0.67 to 1.00； variation coefficient from 0.10 to 0.26 and the coefficient of coordination was 0.115 （P＜0.001）， which indicating the system was reliable.
