Objective:To reduce the approval attitude to domestic violence by psychological intervention for high-risk target groups.Methods:Two districts were randomly selected from the total 5 districts in Changsha,and 93 couples with high risk of spousal violence were screened from a random sample of 317 couples.They were divided into intervention group(42 couples)and control group(51 couples).Mental health education and trainings to prevent from spousal violence were provided to the intervention group 6～7 times within 6 months,while no intervention methods were provided to the control group.After 6 months,25 couples in the intervention group and 37 couples in the control group completed the investigation and evaluation on domestic violence attitude.Results:After 6 months,the number of couples that accepted or partly accepted domestic violence was reduced(15 couples vs.25 couples),also less than that of the control group( 43 couples).No significant difference was found in the control group between before and after the intervention(P>0.05).Conclusion:The psychological intervention to the newly-married couples can change their attitudes to domestic violence.

Objective To investigate the distribution of death among human immunodeficiency virus/acquired immuno deficiency syndrome(HIV/AIDS) cases in Guizhou Province from 1995 to 2017. Methods The HIV/AIDS death cases from 1995 to 2017 were downloaded from “Chinese National Comprehensive HIV/AIDS Prevention and care Information system” in Guizhou Province and were analyzed. Results From 1995 to 2017, Guizhou Province reported a total of 43 794 HIV/AIDS cases and 11 527 deaths according to current address. After excluding missing persons, the HIV/AIDS mortality rate of the province was 29.8%. The proportion of reported HIV/AIDS cases died in the same year ( 21995-2012=139.5, P<0.001; 22012-2015=28.2, P<0.001) and the proportion of HIV/AIDS cases ( 21995-2012=109.1, P<0.001; 22012-2014=57.2, P<0.001) who survived at the beginning but died later in the year all showed a trend being low-high-low. In the analysis of the detection history of death cases, the detection proportion of cluster of differentiation 4(CD4) T-cell and the proportion of antiviral treatment had been increasing year by year. The analysis of the cause of death found that the proportion of death caused by AIDS increased firstly and then declined, and the proportion of death due to excessive drug abuse showed a trend of declining year by year. Conclusions The mortality rate of HIV/AIDS in Guizhou Province was still high, and decreased rather slow. Expanding the coverage of HIV monitoring and screening is one of the key tasks of AIDS prevention and control. CD4+T-cell testing and free antiviral treatment should be strengthened to reduce the mortality rate of HIV/AIDS in Guizhou Province in the future.

This study was aimed to investigate the estrogenic effects ofCoicis Semen in order to preliminarily discuss the mechanism. Mouse uterine weight test and MCF-7 cell proliferation assay were used to evaluate the estrogenic effects ofC. Semen. Reporter gene assays were adopted to explore the action mechanism ofC. Semen. In reporter gene assay, HEK293 cells were co-transfected with pERE-TAL-luc, pβgal-Control, pCXN2-hERα, or pCXN2-hERβ. And the expression of reporter gene luc was controlled by ERE. Mouse uterine weight test showed that compared with the control group, the aqueous extracts ofC. Semen can increase the uterus index of premature female mice (P<0.01). It can significantly promote the proliferation of MCF-7 cells in the medium without estrogen (P<0.01). The reporter gene controlled by ERE technology showed thatwhen mediated by ERα or ERβ respectively, the normalized luciferase activity of aqueous extracts ofC. Semen was significantly higher than activity of the control group (P< 0.05 orP< 0.01). It was concluded that the aqueous extracts ofC.Semen can increase the uterus index of premature female mice and promote the proliferation of MCF-7 cells in the medium without estrogen. We found the estrogenic effects ofC. Semen for the first time. And the estrogenic effects ofC. Semen were mainly mediated by ERβ.

OBJECTIVESTo study the relationship between liver pathology and clinical characters of chronic HBV carriers.

METHODSAnalyze the age, sex, grade of liver inflammation and stage of liver fibrosis among patients with chronic HBV carriers (n = 58) and non-active HBsAg carriers (n = 32), and compare the grade of liver inflammation and stage of liver fibrosis in different groups according to age, ALT levels and with/without HBeAg. The data was processed by using t test or Chi-square test for statistical analysis, respectively.

RESULTS(1) No differences existed in gender composition ratio between chronic HBV carriers and non-active HBsAg carriers. However, the ages of non-active HBsAg carriers group (35.2+/-7.6) were much older than that of the HBV carriers group (24.7+/-4.8) (t = 2.576, P = 0.017). (2) The stage of liver fibrosis in non-active HBsAg carriers group was more aggravated than that of the chronic HBV carriers group (Chi-square = 23.231, P less than 0.01), whereas no significant differences existed between these 2 groups (Chi-square = 0.058, P = 0.972). (3) As to the grade of liver inflammation and the stage of liver fibrosis, significant differences existed between the groups with higher level of serum ALT (20-40 U/L) and lower level ( is less than or equal to 20 U/L) (Chi-square = 7.827, P = 0.008; Chi-square = 14.303, P = 0.001), and similar results also existed between elder group (more than 40) and younger group (is less than or equal to 40) (Chi-square = 10.949, P = 0.001; Chi-square = 21.271, P less than 0.01); (4) Among the chronic HBV carriers, significant differences existed in grade of liver inflammation between groups with HBeAg positive and negative patients (Chi-square = 10.275, P = 0.002), and the latter was more aggravated; however, there was no difference in stage of liver fibrosis between them (Chi-square test = 3.457, P = 0.178).

CONCLUSIONLiver histopathology can be recommended to guide the clinical diagnosis and treatment, especially for the chronic HBV carriers, with elder age, ALT close to normal and HBeAg negative.

OBJECTIVEAim of the present study was to investigate the effect of chronic trimetazidine treatment on atrial energy metabolism and endothelial function in a canine model of chronic atrial fibrillation (AF).

METHODSEighteen canines were randomly divided into sham-operated group (n = 6), atrial pacing group (n = 6), and trimetazidine group (n = 6). In atrial pacing group and trimetazidine group, dogs were atrial paced at 400 beats per minutes for 6 weeks. Trimetazidine at 5 mgxkg(-1)xd(-1) was given one day before rapid atrial pacing for 6 weeks. Creatine phosphate (CrP), adenosine triphosphate (ATP), adenosine diphosphate (ADP) and adenosine monophosphate (AMP) in atrial tissue were analyzed by high-performance liquid chromatography. Total adenosine (TAN) was calculated. The expression of endothelial nitric oxide synthase (eNOS) in atrial tissue was determined by Western blot and immunohistochemical staining. In addition, plasma levels of von Willebrand factor (vWF) was quantified with enzyme-linked immunoadsorbent assay and NO(2)(-)/NO(3)(-) (NOx) was determined by nitrate reductase method.

RESULTSAtrial CrP (P < 0.01) and CrP/ATP were significantly decreased in paced atrium compared to atrium from sham-operated group (P < 0.05) while ATP, ADP, AMP and TAN remained unchanged (all P > 0.05). Plasma vWF was significantly increased and plasma NOx significantly decreased in paced animals compared to sham-operated animals. Atrial expression of eNOS was also significantly reduced in paced animals (P < 0.01). Trimetazidine treatment did not alter the contents of CrP, ATP, ADP, AMP and TAN, but significantly increased atrial eNOS expression (P < 0.05), decreased plasma vWF (P < 0.01) and increased plasma NOx concentration.

CONCLUSIONTrimetazidine treatment affect chronic AF induced disturbance in energy metabolism but may improve endothelial function through a NOx depended manner.

BACKGROUNDRenin-angiotensin-aldosterone system has been demonstrated to be associated with both congestive heart failure (CHF) and atrial fibrillation (AF). This study investigated the effects of spironolactone, a kind of aldosterone antagonist, on atrial electrical remodeling and fibrosis in CHF dogs induced by chronic rapid ventricular pacing.

METHODSTwenty one dogs were randomly divided into sham-operated group, control group, and spironolactone group. In control group and spironolactone group, dogs were ventricular paced at 220 beats per minute for 6 weeks. Additionally, spironolactone at 15 mg x kg(-1) x d(-1) was given to dogs 1 week before rapid ventricular pacing until pacing stopped. Transthoracic and transoesophageal echocardiographic examinations were performed to detect structural and functional changes of the atrium. Swan2 Ganz floating catheters were used to measure hemadynamics variances. Atrial effective refractory period (AERP), AERP dispersion (AERPd), intra- and inter-atrium conduction time (CT) and intra-atrium conduction velocity (CV) were determined. The inducibility and duration of AF were also measured in all groups. Finally, atrial fibrosis was quantified with Masson staining.

RESULTSAERP did not change significantly after dogs were ventricular paced for 6 weeks. However, AERPd, intra- and inter-atrium CT increased significantly, and CV decreased apparently, which was negatively correlated to the atrial fibrosis (r = -0.74, P < 0.05). Simultaneously, left atriums were enlarged and cardiac hemadynamics worsened in pacing dogs. Although spironolactone could not affect cardiac hemadynamics effectively, it can obviously improve left atrial ejection fraction (P < 0.05). Spironolactone treatment did not alter AERP duration, but this medicine dramatically decreased AERPd (P < 0.05), shortened intra- and inter-atrium conduction time (P < 0.05), and increased atrium CV. Moreover, spironolactone decreased the inducibility and duration of AF (P < 0.05), as well as atrial fibrosis (P < 0.01) induced by chronic rapid ventricular pacing.

CONCLUSIONSpironolactone contributes to AF prevention in congestive heart failure dogs induced by chronic rapid ventricular pacing, which is related to atrial fibrosis reduction and independent of hemadynamics.

OBJECTIVETo investigate the efficacy and safety of an extended course (96-week) of combination treatment with peginterferon alfa-2a (Peg-IFNa-2a; 40 kd] plus adefovir (ADV) for treating chronic hepatitis B (CHB) in Chinese patients with negativity for hepatitis B e antigen (HBeAg).

METHODSA total of 25 consecutive patients with HBeAg-negative CHB were administered Peg-IFNa-2a (135-180 mug/week) plus ADV (10 mg/day) for 96 weeks. All patients were followed-up for 24 weeks after treatment completion. Levels of hepatitis B virus (HBV) DNA and hepatitis B surface antigen (HbsAg) were measured by fluorescence quantitative polymerase chain reaction (FQ-PCR) and chemiluminescent microparticle immunoassay, respectively, at 12-week intervals throughout the treatment course and at the end-of-follow-up (week 120). Patients underwent serological analysis at 3-6 month intervals during treatment and follow-up to evaluate occurrence of adverse events; serological parameters included blood count, markers of liver, kidney and thyroid function, and levels of autoantibodies and creatine kinase.

RESULTSFor all patients, the 96-week course of Peg-IFNa-2a plus ADV reduced the level of HBV DNA below the detection threshold (less than 500 copies/ml by FQ-PCR). The overall rate of HBsAg seroconversion was 12% (3/25) at week 48, 28% (7/25) at week 96, and 32% (8/25) at week 120. The occurrences of adverse events were similar at week 48 and week 96.

CONCLUSIONThe extended-course Peg-IFNa-2a plus ADV combination therapy achieved a 100% virological response and better rates of HBsAg seroconversion than 48 weeks of therapy, without a decrease in safety.

BACKGROUNDAlthough coronary heart disease (CHD) is one of the major cardiovascular diseases, risk factors associated with the health-related quality of life (HRQoL) of CHD patients remain unclear. The present study was designed to determine the profile and significant factors of the HRQoL in CHD patients.

METHODSA cross-sectional study was conducted in rural communities of Fangshan District, Beijing, China. Socio-demographic, lifestyle, and comorbidity information of CHD patients were collected by a structured questionnaire and medical records. HRQoL was measured using European Quality of Life 5-dimensions (EQ-5D) scale and EQ Visual Analog Scale (EQ-VAS). Multiple linear and logistic regressions were performed to explore the association of potential risk factors with HRQoL scores and each EQ-5D, respectively.

RESULTSTotally, 1928 CHD patients (mean age 61.64 ± 9.24 years; female:male = 2.4:1) were enrolled in the study. The mean score of EQ-5D index and EQ-VAS were 0.889 ± 0.172 and 71.56 ± 17.65, respectively. Multiple linear regression revealed that marital status, physical activity, moderate alcohol drinking, and family's population were positive independent correlates of EQ-VAS, whereas diabetes mellitus and stroke were negative independent correlates (all P < 0.05). Age and stroke were negatively while physical activity, moderate alcohol drinking, family's population and household income were positively correlated with EQ-5D index (all P < 0.05) independently. In addition, each of the five HRQoL dimensions had various specific determinants, including obesity, underweight, smoking or education.

CONCLUSIONSFindings of the study highlight certain socio-demographic, lifestyle factors, and comorbid stroke or diabetes mellitus as correlates of HRQoL in Chinese CHD patients. Large-scale cohort studies should be carried out to confirm our results in the future.
