Objective:Based on the level evaluation model of tuberculosis control established by analytic hierarchy process model, put forward the method of comprehensive evaluation of the quality of tuberculosis(TB) control and prevention work.Methods: The evaluation target of tuberculosis disease control and prevention was analyzed using analytic hierarchy process. At the same time, the weight of each evaluation index was established by the comparison of the pairwise comparison judgment matrix. And 3 TB control institutions in Beijing were evaluated.Results:Using this model, the comprehensive evaluation index of 3 TB control institutions was 65.6, 54.2 and 57.7 respectively.Conclusion: Analytic hierarchy process is a combination of qualitative and quantitative analysis. It is comprehensive, flexible and simple. At the same time, it is a good method for the evaluation of tuberculosis control and prevention in hospitals, and can be used as an effective tool for the management of tuberculosis control and prevention.

Objective To investigate the effect of three response styles and the ratio scores on Chinese adolescent depressive symptoms,and to investigate the gender differences of response styles and the moderation effects of gender on the relations between response styles and depressive symptoms.Methods The response style questionnaire and the Children's Depression Inventory (CDI) were adopted to measure 932 adolescent twins.Results (1)Rumination was positively associated with adolescent depressive symptoms (r=0.485),positive response styles were negatively associated with adolescent depressive symptoms (r =-0.331).(2) Ratio score was positively associated with adolescent depressive symptoms(r=0.586) and the correlation between ratio score and depressive symptoms was even higher than that between response styles and depressive symptoms.(3) Gender differences of response styles were not significant in Chinese youth samples.(4)Gender moderated the relation between rumination and depressive symptoms(β=-0.07,P＜0.05).Conclusion Ratio scores can explain the relationship between response styles and depressive symptoms better than each of the three individual response styles,and the association between rumination and depressive symptoms is higher in girls.

Objective To investigate the role of tumor suppressor gene PTEN(phosphatase and tension homologue deleted on chromosome 10,PTEN)in apoptosis of ectopic endometrial cells induced by gestrinone. Methods Ectopic endometrium cells obtained from endometriosis were cultured and exposed to gestrinone in different concentrations. The inhibition of the cells during 48 hours was determined by MTT assay, and the cell growth curve was plotted. Then the morphological changes in cells treated with gestrinone for 24h were observed with transmission electron microscope, and the apoptosis rate, cell cycle of the cells and PTEN expression were assessed with flow cytometry analysis (FCM) at the same time. Results Gestrinone in different concentrations could inhibit the growth and proliferation of ectopic endometrium cells in a does and time dependent manner, and the cell growth curve was changed accordingly. After 24 hours exposure to gestrinone in the concentrations of 10 -6 to10 -4 mol/L, some apoptotic changes were observed in the cells under transmission electron microscope. FCM showed that after the exposure to gestrinone, the apoptotic rate of ectopic endometrial cells was 1.3% in 10 6 mol/L group and 15.0% in 10 -4 mol/L group, indicating that there was significantly increase in apoptosis when compared with the control group. At the same time the level of PTEN expression was also increased. Conclusion Gestrinone can significantly inhibit the growth and proliferation of ectopic endometrial cells in endometriosis, and this effects seems to be related to an increase in PTEN expression.

Background Phacoemulsification for hard nuclear cataract is easy to cause corneal edema and posterior capsular rupture.Researches determined that soft-shell technique phacoemulsification can effectively reduce corneal edema,but the risk of posterior capsular rupture during the surgery is still existed.Whether intra-capsular bag soft-shell technique can protect the posterior capsular of lens from rupture is still unclear.Objective This study was to observe the effect of intra-capsular bag soft-shell technique phacoemulsification on hard nuclear cataract.Methods A prospective cohort study was designed.One hundred and sixty-eight eyes of 160 patients with age-related cataract and Ⅳ-Ⅴ grade of nucleus were enrolled in Affiliated Second Hospital of Zhengzhou University from November 2013 to May 2015 under the approval of Ethic Commission and informed consent of the patients.The eyes were randomized into the intra-capsular soft-shell technique group and conventional soft-shell technique group with the matched age,gender and nuclear hardness in a manner of randomized block design.A 3.0 mm incision of cataract phacoemulsification with soft-shell technique in capsular bag was performed on 80 eyes of 78 patients in the intracapsular soft-shell technique group,and conventional soft-shell technique phacoemulsification was performed on 88 eyes of 82 patients in the conventional soft-shell technique group.Intraoperative records including the cumulative dissipated energy,effective phacoemulsification time and posterior capsular changes were recorded during the surgery.Postoperative follow-up indexes included corneal edema,endothelial cell density,BCVA and intraocular pressure changes.Results The mean cumulative dissipated energy and operation duration were (20.13 ± 8.34) ％ and (14.28-±2.17) minutes in the intra-capsular soft-shell technique group,and those in the conventional soft-shell technique group were (19.67±5.24)％ and (15.36±3.49) minutes,showing significant differences between them (t =0.216,P =0.376;t =0.403,P-=0.518).Posterior capsular rupture occurred in 1 eye in the intra-capsular softshell technique group and 7 eyes in the conventional soft-shell technique group.The percentages of eyes with BCVA ≥ 0.5 were 78％,83％ and 92％ in postoperative 1 day,1 week and 1 month in the intra-capsular soft-shell technique group,and those in the conventional soft-shell technique group were 56％,71％ and 89％,with a significant increase in postoperative 1 day,1 week in the intra-capsular soft-shell technique group (x2 =5.130,P =0.027;x2 =4.361,P =0.032).The corneal endothelial cell loss rates were 6.97％ and 7.19％ in the intra-capsular soft-shell technique group and conventional soft-shell technique group respectively in postoperative 3 months,with no significant difference between them (P＞0.05).The intraocular pressure was (20.16±4.23) mmHg (1 mmHg =0.133 kPa) in postoperative 1 day in the intra-capsular soft-shell technique group,which was significantly higher than (17.38± 5.21) mmHg in the conventional soft-shell technique group (t =1.241,P =0.037).Conclusions Intra-capsular bag soft-shell technique phacoemulsification for hard nuclear cataract can decrease the intraoperative and postoperative complications and quicken the visual recovery after surgery.

Objective:To determine whether laser in situ keratomileusis(LASIK) affects the central 30-degree visual field.Methods:This clinical trial comprised 31 patients(61 eyes)scheduled to have LASIK for myopia or myopic astigmatism.Automated static perimetry was performed before and 1 week,6 months after the surgery using the Octopus 1-2-3 perimetry.The main outcome measures were the meao sensitivity(MS) change in the central 15-degree visual field and the MS change in the 15-to 30-degree visual field.The preoperative and postoperative MS values were calculated,and the difference between them(delta MS) was determined.Statistical analysis were performed by SPSS12.0 using the randomized complete block design ANOVA(two factors analysis of variance).Differences among variables were evaluated by q-test. Results:One week after the operation,all uncorrected visual acuity equal to or better than 4.7.Six months after operation,visual acuity distributed between 4.9 and 5.2. There was no significant change in the central 15-degree visual field MS,neither 1 week nor 1 month after the operation;between 15 and 30 degrees,there was a statistically significant decrease.One week after the operation,the delta MS value was(-0.91?1.42)dB(mean?standard deviation);6 month after the operation,the delta MS value was(-0.87?1.38)dB. Conclusion:Automatic static perimetry can detect decreased sensitivity in the 15-to 30-degree visual field after myopic LASIK.It may be a useful quantitative subjective test for measuring the vision quality after refractive surgery in future.

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) with multiple differentiation potential can be induced into osteogenic or adipogenic differentiation under certain conditions. OBJECTIVE: To review the related factors regulating the adipo-osteogenic differentiation of BMSCs. METHODS: A computer-based search of CNKI and PubMed databases was performed for literature concerning the related factors regulating the adipo-osteogenic differentiation of BMSCs published from January 2006 to August 2016. The search terms were bone marrow mesenchymal stem cells, osteogenic differentiation, adipocyte differentiation in Chinese and English, respectively. RESULTS AND CONCLUSION: Signaling pathways, transcription factors, and smal molecule compounds that are interacted are key factors in the regulation of BMSCs differentiation, so the techniques to intervene BMSCs differentiation based on these key molecules may correct bone or fat abnormality and can be applied to tissue engineering and regenerative medicine in the future. Additionally, the biological clock is also one of the most important factors for adipo-osteogenic differentiation of BMSCs by regulating signaling pathways or transcription factors.

Objective To investigate the effects of exposure of gravid rats to the persistent organic pollutants (POPs), methoxychlor (MXC), on the placenta and their progeny during gestation periods. Methods According to different dosage levels of MXC [16, 32, 64 and 0 mg/(kg?d)], forty female SD rats aged 3-month were randomly divided into low-dosage group, mid-dosage group, high-dosage group and control group, with 10 animals for each. All the rats received intraperitoneal injection of MXC for 20 days. The influence of MXC on placenta of gravid rats and their progeny were observed in all aspects. Results With the increase in MXC dosage, intense changes were found in the rats, including an inerease in the number of corpus luteum of ovary, the number of nidation, fetal death and merging fetal (P

Objective: To systematically evaluate the incidence of falls among empty nesters in China, so as to provide the evidence for preventing falls among empty nesters. Methods: Publications pertaining to cross-sectional studies of falls among empty nesters in China were retrieved from international and national databases, including CNKI, Wanfang Data, VIP, Cochrane Library, Web of Science and PubMed from inception to August, 2022. Meta-analysis was performed using the software Stata 15.1, and the combined incidence and 95%CI of falls among empty nesters in China was analyzed. Sensitivity analysis was performed using the leave-one-out method to evaluate the stability of outcome indicators. In addition, the publication bias was evaluated using Funnel plot. Results: Initially, 795 articles were screened in the literature, and 17 articles were finally included, covering 5 468 participants. Meta-analysis revealed that the incidence of falls among empty nesters in China was 23.0% (95%CI: 16.6%-29.5%). Subgroup analysis showed that the incidence of falls among empty nesters published from 2016 to 2022 was higher than that from 2008 to 2015 (20.4% vs. 17.3%; P<0.05). The incidence of falls among empty nesters in western regions was higher than that in eastern and central regions (27.4% vs. 15.9% and 15.0%; P<0.05). The incidence of falls among empty nesters in urban areas was higher than that in rural areas (20.8% vs. 9.9%; P<0.05). Sensitivity analysis showed that the study results were stable, and the funnel plot identified some publication bias. Conclusion The incidence of falls among empty nesters in China was 16.6% to 29.5%, and it is recommended to strengthen the assessment and prevention of risk factors of falls among empty nesters.
