Objective To analyze the prevalence and influencing factors of anxiety and depression among pregnant women in Jianyang City. Methods Convenience sampling method was used to select 322 pregnant women in Jianyang Maternal and Child Health Hospital of Jianyang City. The depression and anxiety of the participants were measured with self-rating anxiety scale(SAS) and self-rating depression scale(SDS)，and the degree of social support was measured with social support rating scale (SSRS). Pearson correlation analysis was used to analyze the relationship between anxiety, depression and social support. The chi square ( 2) test and the non-conditional Logistic regression model were used to analyze the influencing factors of anxiety and depression. Results Anxiety rate and depression rate of pregnant women in Jianyang city were 5.3% and 5.6% respectively. There was a negative correlation between anxiety, depression and social support (P<0.05). Absence of prenatal examination (OR=4.554, 95% CI: 1.063-19.510) was a risk factor for anxiety among pregnant women in Jianyang City. Late pregnancy (OR=5.381, 95% CI: 1.422-20.363) and medium degree of social support (OR=4.150, 95% CI: 1.198-14.375) were risk factors for depression among pregnant women in Jianyang City. Junior high school (OR=0.015, 95% CI: 0.001-0.275), high school or technical secondary school (OR=0.004, 95% CI: 0.001-0.128), junior college or above (OR=0.053, 95% CI: 0.003-0.851) were protective factors for depression. Conclusions The prevelance of anxiety and depression in pregnant women cannot be ignored. It is important to carry out mental health intervention according to the above factors.

Background: In China, secondary cytoreductive surgery (SCR) has been widely used in ovarian cancer (OC) over the past two decades. Although Gynecologic Oncology Group-0213 trial did not show its overall survival benefit in first relapsed patients, the questions on patient selection and effect of subsequent targeting therapy are still open. The preliminary data from our pre-SOC1 phase II study showed that selected patients with second relapse who never received SCR at recurrence may still benefit from surgery. Moreover, poly(ADP-ribose) polymerase inhibitors (PARPi) maintenance now has been a standard care for platinum sensitive relapsed OC. To our knowledge, no published or ongoing trial is trying to answer the question if patient can benefit from a potentially complete resection combined with PARPi maintenance in OC patients with secondary recurrence. Methods SOC-3 is a multi-center, open, randomized, controlled, phase II trial of SCR followed by chemotherapy and niraparib maintenance vs chemotherapy and niraparib maintenance in patients with platinum-sensitive second relapsed OC who never received SCR at recurrence. To guarantee surgical quality, if the sites had no experience of participating in any OC-related surgical trials, the number of recurrent lesions evaluated by central-reviewed positron emission tomography–computed tomography image shouldn't be more than 3. Eligible patients are randomly assigned in a 1:1 ratio to receive either SCR followed by 6 cyclesof platinum-based chemotherapy and niraparib maintenance or 6 cycles of platinum-based chemotherapy and niraparib maintenance alone. Patients who undergo at least 4 cycles of chemotherapy and must be, in the opinion of the investigator, without disease progression, will be assigned niraparib maintenance. Major inclusion criteria are secondary relapsed OC with a platinum-free interval of no less than 6 months and a possibly complete resection. Major exclusion criteria are borderline tumors and non-epithelial ovarian malignancies, received debulking surgery at recurrence and impossible to complete resection. The sample size is 96 patients. Primary endpoint is 12-month non-progression rate.

Objective To evaluate the quality of life in pregnant women with hepatitis B positive and to explore its influencing factors. Methods Eighty pregnant women with positive hepatitis B were randomly selected from Jan. to Apr. 2018 in Jianyang Maternal and Child Health Hospital as the case group, and 323 normal pregnant women were selected as the control group. A face-to-face survey was conducted using the Concise Health Survey Scale SF-36. t test, ANOVA and multiple linear regression were used for statistical analysis. Results The scores of PF and RP in the case group were lower than those in the control group, and the scores of GH in the case group were higher than those in the control group. Analysis of the factors affecting the quality of life of the case group found that the more severe the early pregnancy reaction, the lower the quality of life score. Conclusions The PF and RP of pregnant women with hepatitis B positive in Jianyang City are worse than those of normal pregnant women. Comprehensive measures should be taken to improve their quality of life.

OBJECTIVETo investigate the factors that influence FeCl-induced mouse mesenteric arteriole thrombosis model.

METHODSPlatelets were isolated from donor mice and labeled with Calcein-AM. Mice were transfused intravenously with Calcein-AM labeled platelets. The influence of mouse ages (3-6 weeks, 6-10 weeks and >10 weeks), transfused platelets counts (1×10, 1×10and 2×10platelets) and concentrations of FeCl(6%, 12%, 24% and 48%) on FeCl-induced thrombosis model were compared.

RESULTSThe occlusion time was 16 min for mice aged 3-6 weeks, which was shorter than that for 6 mice aged 6-10 weeks(25 min)(P<0.05) and that for mice aged >10 weeks(38 min)(P<0.01). The occlusion time resulting from transfusion of 1×10and 2×10of pletclets was 15-18 min, which was shorter than that of transfusion 1×10platelets (30 mins). The occlusion time resulting from transfusion of 6% and 12% FeClwas from 15 to 20 min, however the transfusion of 24% and 48% FeClall in all leads to vessel occlusion within 10 min.

CONCLUSIONThe factors influencing the success of FeCl-induced mouse thrombosis model are more. Transfusion of 1×10to 2×10labeled platelets to 3-6 week-old mice, and 6% to 12% of FeClshould be used to induce thrombosis, and the experimental conditions should be optimized for this animal model, therefore, it is easier for us to set up a mouse mesenteric arteriole thrombosis model.

OBJECTIVEThis study was to investigate the HIV current situation in Liangshan prefecture, in order to predict prevalence and transmission trends.

METHODSRegion-specific population, behavior, serosurveillence, and policy/program data (from 1995 to 2010) were gathered from various local and national organizations and applied to the Asian Epidemic Model (AEM) and used to derive estimates of future HIV prevalence, epidemic trends, and outcomes of intervention strategies.

RESULTSThe AEM projections for 2020 included increased number of people living with HIV (PLHIV; to 136 617), increased HIV prevalence (2.51%), and 8037 deaths from acquired immunodeficiency syndrome (AIDS) in this region. However, the overall HIV incidence rate (per 10 000) was projected to decline from 27 in 2015 to 22 in 2020, largely due to a predicted decrease in HIV infection rate (per 10 000) from 658 in 2013 to 621 in 2020 among intravenous drug users. In contrast, the cases of HIV infection per 10 000 was projected to increase from 420 in 2010 to 503 in 2020 among men who have sex with men, and from 8 in 2010 to 15 in 2020 among the general population. The predominant risk factor for HIV transmission over the next decade in Liangshan was casual sex. Community-based outreach strategies to reduce injected drug use and casual sex, and to promote condom use, were predicted as effective interventions to decrease HIV transmission.

CONCLUSIONImplementation of a comprehensive public health program, with targeting to the region-specific at-risk populations, will help to mitigate HIV/AIDS spread in Liangshan.

OBJECTIVEThe aim of the study was to establish the contemporary epidemiological characteristics of Japanese encephalitis (JE) in Guizhou Province.

METHODSA retrospective study of National Notifiable Disease Reporting System (NNDRS) data from 1971 through 2009, was conducted to ascertain the geographical, seasonal, and age distributions of JE incidence in Guizhou Province, China.

RESULTSA total of 68 425 JE cases were reported in Guizhou from 1971-2009. The JE cases occurred sporadically in all 9 prefectures of Guizhou, mostly among residents of rural areas. Seasonal distribution of JE remained consistent over the period from 1971-2009 with the main transmission season starting from June to September and peaking in August. JE occurred mainly in children under the age of 15 years with peak incidence in the 0-6-year age group. Pearson's correlation analysis showed that JE vaccine distribution had a negative correlation with JE incidence rates during 1971-2009 (coefficient of correlation=-0.475, P<0.01).

CONCLUSIONOver the period of 1971-2009, the JE incidence rate had declined dramatically in terms of geographical and age distributions due to JE vaccination to children at risk.

Objective To assess the efficacy of HIV/AIDS prevention and control among long-distance drivers in China. Methods Based on the principles and methods of Cochrane systematic reviews, we searched literature from CBM (from 1978 to 2009), VIP (1989 to 2009) CNKI (1980 to 2009) , and MEDLINE (1950 to 2009) and also assessed the risk of bias of the included before-after studies according to Newcastle-Ottawa scale and their characteristics. Cochrane Collaboration's software RevMan 5.0 was used for Meta-analysis. Results 13 studies were included, with most of them were of low quality as having high risk of bias. (1) Knowledge index 1 :We included 7 'pre-posr'studies. Meta-analysis showed that AIDS/HIV prevention and control was effective in promoting the knowledge index 1 among long-distance drivers (RD=0.15, 95% CI:0.04-0.26). (2) Knowledge index 2: We included 10 pre-post studies, in which the results from Meta-analysis showed that AIDS/HIV prevention and control was effective in promoting the knowledge index 2 among long-distance drivers (RD = 0.24,95 %CI: 0.17-0.30). (3) Behavior index:We included 6 pre-post studies in which the results from Meta-analysis showed that AIDS/HIV prevention and control was effective in promoting the behavior index among long-distance drivers (RD=0.15,95% CI 0.10-0.19). Conclusion Current evidence demonstrated that HIV/AIDS prevention and control programs were effective.

Objective To investigate the effects of interactions among environmental factors, bone morphogenetic protein-4 ( BMP4 ) and transforming growth factor beta-3 ( TGF-β3 ) polymorphisms on nonsyndromic cleft lip and cleft palate (NSCLP) . MethodsThe data of environmental exposures were collected with questionnaires.Genotypes were determined with techniques of polymerase chain reactionrestriction fragment length polymorphism. Interactions between genes, environmental factors and NSCLP were analyzed using multifactor dimensionality reduction (MDR) method. The interactions were validated by logistic regression analysis. ResultsThere was no correlation between three single nucleotide polymorphism (SNP) associated with NSCLP. The developmental accident of NSCLP had higher risk in the interaction between BMP4 T538C, maternal passive smoking and infection in first trimester pregnancy, as well as in the interaction of six factors between TGF-β3 G15572-, maternal passive smoking, infections, multivitamin supplement in the first trimester pregnancy, paternal smoking and high risk drinking before realizing pregnancy than in other interactions of environmental factors. The results could be validated by logistic regression analysis.Conclusions The NSCLP is induced by the interactions between genes and environmental risk factors.
