Objective To analyze family clustering of inpatient service utilization in rural areas of Hubei Province.Method Inpatient service information of all families in rural areas of sample counties was obtained on the basis of New Cooperative Medical System (NCMS) inpatient database;Lorentz curve was drawn by area graph and scatter diagram of Excel 2010,so was Gini coefficient;descriptive statistic,variance analysis and so on were carried by IBM SPSS Statistic 20.0.Result 3％ family takes up 19％ inpatient service,and rural family's Gini coefficient of inpatient service utilization is 0.366;high inpatient service utilization family(HIUF) uses less outpatient service(29.2±26.9) than middle inpatient service utilization family (31.7±23.5).Inpatient member of HIUF used more inpatient service than other families,except the low inpatient service utilization member(NHH9.2＞NMH4,NHM2.4＞NMM2.2＞NLM1.7);HIUF use least time to reach county hospital(tH44.3＜tM44.9＜tL45.2),have more inpatient members than others (NM＞4.5＞NH4.4＞NL3.9).Conclusion Great family clustering of inpatient service utilization exists in rural area,and irrationality exists in some way;more outpatient service utilization may reduce inpatient service utilization.

Objective To analyze family clustering of outpatient service utilization in rural areas of China.Method Outpatient service information of all families in rural area of sample county was obtained on the basis of new cooperative medical system (NCMS) outpatient database,and family outpatient service utilization database was cleared out with the help of functions like IF,LOOKUP and so on in Excel 2010.Lorentz curve was drawn by area graph and scatter diagram with Excel 2010,so was Gini coefficient.Descriptive statistic,variance analysis and so on were carried by IBM SPSS Statistic 20.0.Result 20％ family takes up 53％ of outpatient service,and rural family's Gini coefficient of outpatient service utilization is 0.516.Members of high outpatient service utilization family (HOUF) used (17.7) more outpatient service than other families (10.4,4.2).HOUF were mainly distributed in towns with high capability of township hospital and low capability of township hospital.Conclusion Great family clustering of outpatient service utilization exists in rural areas.Family homogenization is distinct,in which irrationality exists.The capability of primary medical institutions influences the outpatient service utilization of residents in rural area.

Objective:To figure out the characteristics of annual medical expenditure for rural residents and its distribution among different population.Methods:The individual annual medical service utilization information was summarized after dealing with the database of the 2014 new rural cooperative medical system by Excel.It prescribed the clustering of medical expenditure by Lorenz curve and Gini index.Descriptive statistics and x2 test were used to compare the characteristics and distribution of the annual medical expenditure among rural residents.The Chi-square test was conducted to compare the differences of the population distribution.Results:The costliest 5％ patients accounted for approximately 68％ of total health care expenditure.The annual total expenditure was 16628 yuan per capita among high-cost population,while low-cost population were 108 yuan.The Gini index of medical expenditure for rural residents was 0.81.Among female and population over 45 years old,the proportion of high-cost population was higher than 5％.People living near provincial road,in flatlands or areas where the ability of township hospital was limited were nore likely to expense higher medical costs,known as 6.40％,5.50％ and 5.80％ separately.Conclusion:Clustering of medical expenditure for rural residents was remarkable,while the expenditure among high-cost,medium-cost and low-cost population were quite different.The elderly,female and primary population living in areas where the ability of township hospitals were limited were more likely to generate high medical costs.

Objective To learn the suitability and validity of readmission service at counties and townships in rural China.Methods Seven pilot counties were randomly selected from the eastern,middle and western areas of China,and five diseases of the respiratory infection and cerebral system were set as the targets,while 600 target inpatient readmitted who had any of the five target diseases from 2012 to 2013 in such counties were selected from the NRCMS database.With expert consultation and empirical evaluation,the fitness of the days of stay at township hospital and necessity of hospitalization at county hospitals were evaluated for such target inpatients.Results 64.7％ of the target inpatients were found with unfit days of stay at township hospitals,mostly too short;59.0％ of the target inpatients' hospitalization at county hospitals were found with serious risk factors during their hospitalization;18.5％ of the inpatients were found with unnecessary hospitalization.Conclusions Hierarchical medical system can enhance the efficiency of the heahhcare system,but the current validity of readmission is poor,so is the fitness of days of stay at township hospitals,and the quality of the referral pattern.These problems mostly result from poor medical competence at township hospitals and high autonomy of patients in seeking medical service anywhere in the country.

Aim To isolate and characterize the human circulating fibrocytes from human peripheral blood and explore the effects of curcumin on human circulating fi-brocytes.Methods The cells were isolated and puri-fied by density gradient centrifugation,and identified by flow cytometry and immunocytochemistry .Then , CCK-8 and flow cytometry were used to study the effect of curcumin on the proliferation as well as COL I ex-pression of human circulating fibrocytes,respectively. Results After being isolated the cells expressed CD34,CD45 and COLⅠ,among which 79.7% were both CD45 and collagen I positive,typical of human circulating fibrocytes.Curcumin could exert regulatory effects on proliferation of human circulating fibrocytes. Exposure of the cells to curcumin for as short as 24 hours promoted their growth,while prolonged treatment (72 h ) significantly inhibited cell propagation and downregulated the COLⅠ levels,best manifested at a concentration as high as 20 μmol · L-1 .Conclusion The proliferation of cells and COLⅠexpressions can be effectively inhibited by curcumin with the prolonged action period and high concentrations.

OBJECTIVETo study the phytoestrogenic effects and their possible mechanisms of Jiaoai tang and Shenqi Jiaoai tang through the tests in mice and ER (+) MCF7 cells.

METHODSixty kunming mice weighing 9-12 g were randomly divided into 6 groups: solvent control group (administrated equal dose of diswater), diethylstilbestrol control group (administrated diethylstilbestrol at a dose of 0.35 mg x kg(-1) x d(-1) and 4 Chinese medicine treated groups (administrated low or high doses of Jiaoai tang and Shenqi Jiaoai tang at 2.5 g x kg(-1) x d(-1) or 5.0 g x kg(-1) x d(-1) respectively). After administration for 4 days, the mice were sacrificed; uterus was removed and weighed, uterus rate was calculated. The blood serum was also separated. The proliferation rate of MCF7 cells influenced by Jiaoai tang and Shenqi Jiaoai tang was determined by MIT assay. PS2, ERalpha and ERbeta mRNA expression was quantified by Real-time PCR assay. Estrogen receptor antagonist ICI182, 780 was employed as a tool.

RESULTAdministration of Jiaoai tang and Shenqi Jiaoai tang at high dose significantly increased uterus rate in mice (P < 0. 05). The pharmacological serum from two high-dosage groups of Chinese herbal medicine decoction significantly enhanced proliferation rate of MCF7 cells (P < 0.05 or 0.01), while their effects were blocked by ICI182, 780 (P < 0.05 or 0.01). The pharmacological serum could cause elevation of pS2 level (P < 0.01) which would be obviously inhibited by ICI182, 780 (P < 0.01). ERalpha and ERbeta mRNA levels were also elevated significantly (P < 0.05 and P < 0.01 respectively).

CONCLUSIONJiaoai tang and Shenqi Jiaoai tang have phytoestrogenic effects, which were attained via ER pathway. They can also increase the mRNA levels of estrogen receptor subtypes, especially ERbeta.

Postmenopausal osteoporosis is one of the commonest systemic bone metabolism diseases among menopausal women, mainly caused by lowering internal estrogen. Although Hormone Replacement Therapy (HRT) is an effective method in clinical practice for years, it shows side-effect in increasing gynecological carcinoma. It has already been proved by clinical tests that multiple traditional Chinese medicine formulas and their monomer ingredients and phytoestrogen-like active constituents contained in traditional Chinese medicines are effective on treating osteoporosis with relatively less side-effects comparing with HRT. They show protective and therapeutic effects by acting on estrogen receptors of targeted tissues and targeted cells and then affecting expressions of bone metabolism-related regulatory proteins and factors in downstream signal conduct paths. Recent studies on estrogen related receptor (ERR) provide new possibilities and pathways for mechanism of traditional Chinese medicine and their active constituents in osteoporosis.
