OBJECTIVE:To put forward suggestions for rectifying the unbalance of the mechanism for coordinating interests in medicine circulation. METHODS:From three aspects of the expression,game and balance of interests,the interest group theory was used to analyze the unbalance of the mechanism for coordinating interests in medicine circulation as well as the cause of the un-balance,and rectification suggestions were put forward. RESULTS&CONCLUSIONS:At present,the mechanism in medicine cir-culation in China is unbalanced,including mechanism for interest expression,for interest game,for interest balance,etc. Corre-sponding rectifications should include perfecting legislation,effectively giving play to the role of media,defining the legal status of the interest group,strengthening organizational building of the vulnerable group,adjusting the interest pattern of the strong and weak groups and strengthening legal and social morality construction.

The authors analyzed the negative impacts on hospital public welfare performance,caused by such organizational elements imbalances of public hospitals,as objective structure,allocation of rights and responsibilities,and budget resources.In view of these setbacks,they proposed countermeasures for timely solution of such imbalances and maxim optimal combination,for the purpose of more effective reform of such hospitals.

Public hospital's public property is mainly reflected in providing people with equitable access, quality and efficiency of basic medical services. However, due to lack of understanding in importance of the medical services positive and negative externalities, lead to the dilution of commonweal of public hospital. Meanwhile, externalities caused by transaction costs and unclear property rights in medical services activities further exacerbate welfare fade. The government should take effective measures to protect and encourage positive externalities, prevent and control the negative externali-ties, and, by way of reducing transaction costs, clear property rights to resolve external effects, as far as possible to pro-tect the public interest in public hospitals.

Objective To evaluate the effect of Angio-Seal vascular closure device by the femoral artery hemostasis.Methods Relative literature was searched by computer,according to the inclusion and the exclusion criteria,which were analyzed by RevMan5.2 software.Results A total of four studies of randomized controlled trial were brought into this research,the total sample size was involved in 3 191 cases,the sample size of the intervention group and the control group respectively was 1 583 and 1 608.The analysis results showed,Angio-seal vascular closure device can significantly shorten the time of hemostasis after femoral artery interventional therapy in patients and the limb braking time.The sensitive analysis results showed that the results stability were high and the conclusions were reliable.Conclusions Application of Angio-seal vascular closure device can significantly shorten the interventional therapy in patients with bleeding time and braking time.

OBJECTIVE:To explore the effects of tamsulosin on proliferation and apoptosis in prostatic cancer PC-3 cells. METHODS:After treated with 0 (blank control group),12.5,25 and 50 μmol/L tamsulosin (tamsulosin low,medium and high-concentration groups)for 48 h,the viability of PC-3 cells was detected by MTT method. Hoechst 33258 staining was used to detect cell apoptosis rate. Western blot was used to determine the expression level of Bax and Bcl-2 protein,and the phosphoryla-tion level of protein kinase B(Akt),mammalian target rapamycin(mTOR),ribosomal S6 protein kinase(p70S6K)and 4E bind-ing protein 1(4E-BP1). RESULTS:Compared with blank control group,PC-3 cells viability and the phosphorylation level of Akt, p70S6K and 4E-BP1 decreased in tamsulosin low,medium and high-concentration groups,while expression level of Bax protein in-creased (P<0.05 or P<0.01);the apoptosis rate of PC-3 cells was increased in tamsulosin medium and high-concentration groups,while the expression level of Bcl-2 and phosphorylation level of mTOR were decreased(P<0.01),in concentration-depen-dent manner. CONCLUSIONS:Tamsulosin can inhibit PC-3 cells proliferation and induce cell apoptosis via blocking Akt/mTOR signal pathway.

Objective:To determine the association between recreational drug usage， high risk sexual behavior， and HIV infection among men who have sex with men（MSM） in Jinhua. Methods:A cross-sectional survey was conducted to recruit MSM for anonymous questionnaire survey and serological examination. We used EpiData3.1 for data entry and SPSS 19.0 for statistical analysis. Results:A total of 368 MSM were surveyed， in which the proportion of recreational drug usage was 13.3% （ 49 / 368 ）， with the HIV infection of 10.3% （38/ 368 ） and syphilis infection of 8.9% （25/368）. Risk factors associated with recreational drug usage were determined to be part-time job or being unemployed （OR=5.26； 95%CI： 2.10-13.18； P<0.001）， average monthly income ≥CNY 5 000 （OR=6.45； 95%CI： 2.87-14.61； P<0.001）， education level of high school or above （OR=1.56； 95%CI： 1.37-3.57； P=0.037）， sexual orientation being homosexual（OR=3.52； 95%CI： 1.60-7.33； P=0.002）， number of sexual partners >1 （OR=4.37； 95%CI： 1.76-10.82； P=0.001）， engaged in group sex （OR=7.90； 95%CI： 2.11-29.55； P=0.002） and previously diagnosed sexually transmitted diseases （OR=4.76； 95%CI： 1.29-17.65；P=0.019）. Conclusion:Prevalence of recreational drug usage among MSM in Jinhua is relatively low. MSM with part-time or unemployed status， monthly income ≥CNY 5 000， higher education level， homosexual orientation， multiple sexual partners， sexually transmitted diseases and group sex behavior are the risk factors associated with recreational drug usage in Jinhua city. Targeted countermeasures should be considered for intervention.

Objective:To analyze the sexual relationship power and its influencing factors in married couples with single human immunodeficiency virus （HIV） positive spouse， and to provide theoretical support for the development of appropriate HIV prevention and control measures. Methods:Data of HIV single positive couples were collected from the database of AIDS epidemic. Social demographic characteristics， AIDS related knowledge， sexual behavior and sexual relationship power of HIV single positive couples were obtained by self-designed questionnaire. Current situation and influencing factors of sexual relationship power of the negative spouses HIV single positive couples' were analyzed. Results:Among 191 HIV negative spouses， 72.3% had not heard of AIDS， 3.1% had a history of HIV testing， and 38.2% had high sexual power. Single factor analysis found that men （χ² =12.227，P<0.001）， high income （χ² =4.227，P =0.040）， high education level （χ² =18.188，P<0.001）， frequent drinking （χ²= 6.104，P=0.013）， and high-level awareness of AIDS （χ²=10.827，P=0.013） had higher power of sexual relationship. Multivariate analysis showed that men and individuals with college education or above had higher sexual power， with OR （95% CI） 4.102 （1.757-9.578） and 7.403 （2.810-19.503）， respectively. Conclusion:The low awareness rate of AIDS knowledge and the disharmonious relationship between husband and wife will increase the risk of AIDS transmission in the spouses. Male， economic income， education level and AIDS awareness rate are the important influencing factors of sexual relationship power.
