Objective Through analysed the questionnaire about postpartum contraception knowledge-attitude-practice (KAP) among obstetricians,to understand the postpartum contraceptive knowledge,idea,attitude and related factors among obstetricians.Methods From October 2013 toDecember 2013,209 obstetricians of 10 different levels of the hospital of Tianjin area had been enrolled in this study,and KAP questionnaire was investigated.Results The knowledge of postpartum contraception among obstetricians was seriously lack,the total correct rate was 34.8％,the lowest score was 5 points,the highest was 80 points,the average score was 34.8± 13.5,more than 60 points accounted for only 2.9％ (6/209).86.6％ (181/209) obstetricians have thought it necessary to carry out postpartum contraceptive propaganda during pregnancy,and 97.6％ (204/209) obstetricians have thought it necessary to develop postpartum contraception training.92.8％ (194/209) and 94.2％ (197/209) obstetricians always informed that pay attention to contraception before discharge and postpartum visit,specific methods were not discussed.Obstetricians obtained relevant progress of contraceptive knowledge mainly through the daily medical work (92.8％,194/209),hoped that approach postpartum contraception related knowlege through continuing education courses (77.5％,162/209),special lectures in academic conference (72.2％,151/209) and special training (67.5％,141/209).Conclusions (1) The postpartum contraception knowledge among obstetricians is seriously lack.(2) The obstetricians hold positive attitude towards the propaganda for postpartum contraceptive knowledge.(3) Postpartum contraception related education only provided before discharging and postpartum visit,and the content was simply inform that pay attention to contraception,specific methods are not discussed.(4) To explore the reason why postpartum contraception situation is not ideal,that's because insufficient attention and propaganda,obstetricians don't update the contraception knowledge,and be lack of knowledge on the efficient,long-acting reversible contraception methods,exaggerated the side effects and complications.

Objective: To investigate the relationship between different physical activity pattern and trajectories of anxiety and depression scores in college students, and to provide evidence for exploring the influence of physical activity on the development of anxiety and depression. Methods: A total of 1 265 college students from grade 2017 in a comprehensive university were investigated longitudinally for five times through stratified cluster sampling. Physical Activity Rank Scale-3(PARS-3), Self-rating Anxiety Scale(SAS), and Self-rating Depression Scale(SDS) were used, and latent class linear mixed models(LCLMM) were used to identify the trajectories of anxiety and depression scores and multinomial Logistic regression models were used for exploring the relationship between small persistent status of physical activity among the five surveys and subgroups of trajectory and anxiety and depression scores. Results: A total of 940(74.3%) college students were indentified as low persistent physical activity group and 325(25.7%) of them were identified as moderatre-to-high persistent physical activity group. The trajectories of anxiety score were classified into three groups:low level group, high level-decreasing group, and high level group. The number and proportion of the three groups were 686(54.2%), 144(11.4%), 435(34.4%), respectively. The trajectories of depression score were classified into four groups:low level group, moderate level-decreasing group, moderate level-increasing group, and high level group. The number and proportion of the five groups were 604(47.8%), 170(13.4%), 177(14.0%), 314(24.8%), respectively. Compared to the students with moderate-to-high persistent physical activity, higher persistent physical activity was associated with higher risk of keeping anxiety score at a high level(OR=1.78), and higher odds of decreasing depression score at moderate level(OR=0.67), as well as with higher risk of increasing depression score from a moderate level(OR=1.79), and increase the risk of keeping depression score at a high level(OR=1.97)(P<0.05). Conclusion Low persistent physical activity of college students could increase the risk of anxiety and depression at a high level. Relevant departments in universities should encourage students to take part in physical activity,with special focus given to individuals with less amount of physical activity and take effective interventional measures to modify the development of anxiety and depression.

Objective:To evaluate the efficacy and safety of drospirenone and ethinylestradiol tablets (Ⅱ) in Chinese women with dysmenorrhea.Methods:This was a single-arm, open-label, interventional, multicenter, post-authorization safety/effectiveness study of drospirenone and ethinylestradiol tablets (Ⅱ) across 6 treatment cycles, a total of 526 patients were included in the dysmenorrhea subgroup. Visual analog scale (VAS) was used to assess the severity of menstrual pain. Secondary outcomes included unintended pregnancies, bleeding pattern, cycle control and safety.Results:After treated with drospirenone and ethinylestradiol tablets (Ⅱ), VAS of pain had decreased significantly compared with baselines [(49.5±23.7) vs (32.3±24.9) vs (20.7±19.4) vs (18.4±18.7) mm, P<0.01]. From the second cycle to the fifth cycle, the incidence of scheduled bleeding increased from 93.9% (450/479) to 96.4% (431/447). The duration of scheduled bleeding decreased from (5.7±2.7) to (5.4±1.8) days. The incidence of intermenstrual bleeding decreased from 9.0% (43/479) to 5.6% (25/447). 17.5% (92/526) patients reported adverse drug reactions, most frequently reported adverse events were breast pain, nausea, breast swelling, headache, and uterine bleeding. No death occurred during the study. Conclusion:Drospirenone and ethinylestradiol tablets (Ⅱ) is effective for the treatment of dysmenorrhea and has good safety.

Hepatitis E virus (HEV) sequences including four major genotypes representative strains available in GenBank were aligned with the DNAMAN software. The highly conserved internal region of ORF2 was then subjected to design primers and a probe. Furthermore, a 0.3 kb fragment of HEV ORF2 containing the amplification region was transcribed in vitro to synthese cRNA standard and a universal real-time TaqMan PCR assay was optimized and developed to detect and quantify main genotypes RNA of HEV. The specificity and reliability of the real-time RT-PCR was confirmed by testing genotype I HEV, genotype IV HEV and clinical samples. The detection limit of real-time RT-PCR was found 2.0 x 10(1) copies per reaction using in vitro transcribed cRNA. Compared with nested RT-PCR in diagnosis of HEV, the real-time RT-PCR developed was 10 to 100-fold more sensitive than the nested RT-PCR. The detection results from 54 clinical specimens indicated real-time RT-PCR was a rapid, sensitive and reproducible diagnostic method for HEV. This assay will be useful as an early and rapid diagnostic assay for HEV.

Objectives To develop a multi-stage and multi-epitope vaccine, which consists of epitopes from the early secretory and latency-associated antigens of Mycobacterium tuberculosis (MTB). Methods The B-cell, cytotoxic T-lymphocyte (CTL) and helper T-lymphocyte (HTL) epitopes of 12 proteins were predicted using an immunoinformatics. The epitopes with antigenicity, without cytotoxicity and sensitization, were further screened to construct the multi-epitope vaccine. Furthermore, the proposed vaccine underwent physicochemical properties analysis and secondary structure prediction as well as 3D structure modeling, refinement and validation. Then the refined model was docked with TLR4. Finally, an immune simulation of the vaccine was carried out. Results The proposed vaccine, which consists of 12 B-cell, 11 CTL and 12 HTL epitopes, had a flexible and stable globular conformation as well as a thermostable and hydrophilic structure. A stable interaction of the vaccine with TLR4 was confirmed by molecular docking. The efficiency of the candidate vaccine to trigger effective cellular and humoral immune responses was assessed by immune simulation. Conclusion A multi-stage multi-epitope MTB vaccine construction strategy based on immunoinformatics is proposed, which is expected to prevent both active and latent MTB infection.
