Objective:To investigate the bioactive components of Sangqi Qingxuan formula(SQQX),predict the pharmacological targets,and explore the mechanism of hypertensive vascular remodeling(HVR).Methods:Network pharmacology was adopted to predict how SQQX acts in HVR.The effectiveness was assessed by blood pressure measurements and pathological morphology observation based on a spon-taneously hypertensive rat model,while the mechanism of SQQX on HVR was validated by immuno-histochemistry(IHC)and western blot(WB)according to the results of network pharmacology.Results:There were 130 bioactive components of SQQX and 231 drug targets predicted by the Traditional Chinese Medicine Systems Pharmacology Database.Subsequently,181 common targets were identified for SQQX against HVR,with TP53,MAPK1,and AKT1 as the core targets.Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses was employed to identify the top 20 enriched functions and the top 20 pathways(P＜.01).Finally,the key role of the ERK/MAPK signaling pathway in HVR was determined.The in vivo results suggested that SQQX reduced systolic blood pres-sure and increased the ratio of thoracic aortic wall thickness to lumen diameter.Additionally,compared with the model group,SQQX increased the expression of smooth muscle 22 alpha(IHC:P＜.001;WB:P＜.05)and decreased the expression of osteopontin(IHC:P＜.001;WB:P＜.05),ERK1/2(IHC:P＜.001;WB:ERK1&ERK2,all P＜.05),p-ERK1/2(IHC:P＜.001;WB:ERK1&ERK2,all P＜.05),and the ratio of p-ERK1/2 to ERK1/2 protein(IHC:P＜.001).Conclusions:SQQX,which has multiple bioactive ingredients and potential targets,is an effective treatment for HVR.The mechanism of antihypertensive and vascular protection may be related to the inhibition of phenotypic transformation of vascular smooth muscle cells and the ERK/MAPK signaling pathway.

Objective To investigate the characteristics and rules of tongue image in patients with chronic fatigue syndrome(CFS)with different fatigue degree.Methods Totally 917 patients with severe chronic fatigue syndrome(severe CFS group),351 patients with mild chronic fatigue syndrome(mild CFS group)and 1216 healthy controls(healthy control group)were enrolled in the physical examination center of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine.The tongue image data of subjects in the three groups were collected using TFDA-1 digital tongue and face diagnostic instrument,and the color space indexes of RGB,HSI,Lab and YCrCb were used to analyze the tongue image differences of CFS people with different fatigue degrees and the tongue image features of CFS patients with liver-qi stagnation syndrome,damp-heat stasis syndrome and spleen deficiency syndrome.Results Compared with the healthy control group,the tongue image indexes TB-R,TB-G,TB-B,TB-I,TB-L,TB-Y,TC-H,TC-I,TC-L and TC-Y increased in the severe CFS group;TB-S,TB-a,TC-S,TC-a,TC-Cr decreased(P<0.05).TB-R,TB-G,TB-B,TB-I,TB-L,TB-Y,TC-R,TC-G,TC-B,TC-I,TC-L and TC-Y increased in severe CFS group compared with mild CFS group.TB-H and TB-b increased in mild CFS group compared with healthy control group.The comparison of syndromes in severe CFS group showed that TB-a,TB-Cr,TC-S,TC-a,TC-Cr and TB-S increased in liver-qi stagnation syndrome compared to damp-heat stasis syndrome;TB-G,TB-B,TB-I,TB-L,TB-Y,TB-b,TB-Cb,TC-G,TC-B,TC-H,TC-I,TC-L,TC-Y and perAll decreased(P<0.05).Compared with spleen deficiency syndrome,TB-a,TB-Cr,TB-CON,TB-ENT,TB-MEAN,TC-a,TC-Cr,TC-CON,TC-ENT,TC-MEAN increased in liver-qi stagnation syndrome;TB-ASM,TC-S and TC-ASM decreased(P<0.05).Compared with spleen deficiency syndrome,TB-a,TB-b,TB-Cr,TB-Cb,TB-CON,TB-ENT,TB-MEAN,TC-G,TC-B,TC-H,TC-I,TC-L,TC-a,TC-Y,TC-Cr,TC-CON,TC-ENT,TC-MEAN,perAll increased;TB-ASM,TC-S and TC-ASM decreased(P<0.05).The comparison of mild CFS syndrome showed that there was no statistical significance between liver-qi stagnation syndrome and spleen deficiency syndrome(P>0.05).TB-Cr,TC-a,TC-Cr and perAll increased and TC-S decreased in damp-heat stasis syndrome compared with spleen deficiency syndrome(P<0.05).TB-S,TB-a,TB-Cr,TC-S,TC-a,TC-Cr increased,and TB-G,TB-B,TB-I,TB-Cb,TB-b,TC-b and TC-Cb decreased(P<0.05)in liver-qi stagnation syndrome compared with damp-heat syndrome.The distribution trend of TC-S was as follows:dampness-heat syndrome

Objective:To describe the current situation of mental health service utilization of community pa-tients with five mental disorders in Inner Mongolia Autonomous Region and provide reference for health education and formulating relevant policies.Methods:The multistage stratified sampling method with unequal probability was used to select a total of 12 315 community residents aged 18 and over in Inner Mongolia Autonomous Region.Using Composite International Diagnostic Interview,mood disorders,anxiety disorders,substance use disorders,intermit-tent explosive disorders,and eating disorders,and health service utilization were investigated.Descriptive statistics was completed by single factor analysis method.Results:The lifetime rates of consultation and treatment of any mental disorder were 18.7％and 10.2％,respectively.The highest proportion of patients received treatment by non-medical professionals was 31.4％,followed by psychiatrists in psychiatric hospital or psychologists in general hospitals.Among the patients,1.1％of them received medication,and 2.5％received psychotherapy.Conclusion:The utilization rate of mental health services in community patients with five mental disorders is relatively low.It is necessary to conduct health education for medical help seeking properly.

OBJECTIVETo investigate the epidemiological characteristics of human infections with avian influenza A (H7N9) in China and to provide scientific evidence for the adjustment of preventive strategy and control measures.

METHODSDemographic and epidemiologic information on human cases were collected from both reported data of field epidemiological investigation and the reporting system for infectious diseases.

RESULTSA total of 433 cases including 163 deaths were reported in mainland China before June 4, 2014. Two obvious epidemic peaks were noticed, in March to April, 2013 and January to February, 2014. Confirmed cases emerged in 14 areas of China. Five provinces, including Zhejiang, Guangdong, Jiangsu, Shanghai, and Hunan, reported about 85% of the total cases. Median age of the confirmed cases was 58 years (range, 1-91), with 70% as males. Of the 418 cases with available data, 87% had ever exposed to live poultry or contaminated environments. 14 clusters were identified but human to human transmission could not be ruled out in 9 clusters.

CONCLUSIONHuman infections with avian influenza A (H7N9) virus showed the characteristics of obvious seasonal distribution, with certain regional clusters. The majority of confirmed cases were among the elderly, with more males seen than the females. Data showed that main source of infection was live poultry and the live poultry market had played a significant role in the transmission of the virus.
