Socioeconomic inequalities in human papillomavirus knowledge and vaccine uptake: evidence from a cross-sectional study in China.

Objective: Providing the human papillomavirus (HPV) vaccine is effective to eliminate the disparity in HPV-related cancers. It is unknown regarding inequality in the distribution of HPV vaccination in China since the vaccine was licensed and approved for use in 2016. This study aimed to examine socioeconomic inequalities in HPV-related knowledge and vaccination and identified factors associated with such inequalities. Methods: Self-administered questionnaires measuring HPV-related knowledge and vaccine uptake were completed by 1,306 women through online survey platform. HPV knowledge was assessed using a 12-item question stem that covered the hazards of HPV infection, HPV vaccine dosage, benefits, and protection. Cluster analysis by combining monthly household income, educational level, and employment status was used to identify socioeconomic status (SES) class. The concentration index (CI) was employed as a measure of socioeconomic inequalities in HPV-related knowledge and vaccination. Linear regression and logistic regression were established to decompose the contributions of associated factors to the observed inequalities. Results: The CI for HPV-related knowledge and vaccine uptake was 0.0442 and 0.1485, respectively, indicating the higher knowledge and vaccination rate were concentrated in groups with high SES. Education and household income made the largest contribution to these inequalities. Age, residency and cervical cancer screening were also important contributors of observed inequalities. Conclusion: Socioeconomic inequalities in HPV-related knowledge and vaccination uptake are evident in China. Interventions to diffuse HPV-related information for disadvantaged groups are helpful to reduce these inequalities. Providing low or no-cost HPV vaccination and ensuring accessibility of vaccines in rural areas are also considered to be beneficial.

Silencing of lncRNA SNHG17 inhibits the tumorigenesis of epithelial ovarian cancer through regulation of miR-485-5p/AKT1 axis.

BACKGROUND: Epithelial ovarian cancer (EOC) stands up for about 90% of ovarian cancer cases, which is the frequent cause of death among women. LncRNAs are involved in progression of EOC. Meanwhile, lncRNA SNHG17 was upregulated in EOC, while the detailed function of SNHG17 in EOC remains unclear. METHODS: Protein and mRNA levels were assessed by western blot and RT-qPCR, respectively. The function of SNHG17 in EOC cells was tested by CCK-8, Ki-67 staining, flow cytometry and transwell assay. Dual luciferase was applied for assessing the relation among SNHG17, miR-485-5p and AKT1. Furthermore, in vivo experiments were applied to test the impact of SNHG17 in EOC. RESULTS: SNHG17 knockdown reduced the proliferation and promoted the apoptosis of EOC cells. Consistently, si-SNHG17 obviously reduced the invasion and epithelial-to-mesenchymal transition (EMT) process of EOC cells. MiR-485-5p was proved to be the target miRNA of SNHG17, and SNHG17 negatively regulated the level of miR-485-5p. MiR-485-5p inhibitor significantly abolished the anti-tumor impact of si-SNHG17 on EOC. AKT1 was identified to be targeted by miR-485-5p, and miR-485-5p negatively modulated AKT1 and p-mTOR levels. Moreover, miR-485-5p mimics reduced the proliferation, migration and promoted the apoptosis of EOC cells via targeting AKT1. Furthermore, si-SNHG17 markedly suppressed EOC growth in vivo. CONCLUSION: SNHG17 silencing inhibits the development of EOC via regulation of miR-485-5p/AKT1 axis. Thus, our study might supply a novel strategy against EOC.

Influence of three combined exercise programs on improving sleep quality among college students with sleep disorders / 中国学校卫生

Objective@#To explore the improvement influence of three combined exercise programs on sleep quality among college students with sleep disorders, so as to provide reference for the construction of exercise intervention programs for sleep disorder.@*Methods@#A total of 35 college students with sleep disorders were randomly divided into AR group ( n =10), AM group ( n =8), RM group ( n =9) and CG group ( n =8). The three exercise groups were provided with exercise intervention for 8 weeks, 3 times/week , 60 min/time, and the CG group maintained previous lifestyle.Before and after the intervention,evaluation of subjective sleep quality and reduction rate of sleep disorder by PSQI, and Actigraph GT3X+ was used to monitor the changes in the objective sleep quality.@*Results@#After the intervention,the total score of PSQI ( t =3.49, 2.31, 2.73), sleep quality score ( t =2.71, 3.00 , 5.29),sleep duration of AR group ( t =2.74), daytime dysfunction of AM group ( t =2.64) and sleep duration of RM group ( t = 2.29) significantly decreased ( P ＜0.05); The scores of sleep duration in AM group were significantly lower than those in AR group, and the scores of PSQI,sleep quality and daytime dysfunction in AM group were significantly lower than those in CG group (P<0.05). After intervention,TST ( t =-4.41, -8.37, -6.79) and SE ( t =-4.40, -5.86, -4.91) of AR group, AM group and RM group significantly increased( P <0.05), SOL ( t =4.18, 9.93), WASO ( t =2.91, 3.46) and NA ( t =4.80, 3.37) of AM group and RM group significantly decreased ( P <0.05). The changes of TST,SE and WASO in RM group were significantly higher than those in CG group, and SOL was significantly lower than those in CG group ( P <0.05).@*Conclusion@#The three kinds of combined exercise programs can improve the subjective and objective sleep quality of college students with sleep disorders, and reduce the incidence of sleep disorders; different combined exercise programs have different influence on the improvement of sleep quality of college students with sleep disorders, aerobic combined meditative movement exercise program has a prominent influence on the improvement of subjective sleep quality, and resistance combined meditative movement exercise program has a prominent influence on the improvement of objective sleep quality.

Therapeutic effects of puerarin on polycystic ovary syndrome: A randomized trial in Chinese women.

BACKGROUND: This study aims to assess the therapeutic effects of a well-known component (puerarin) obtained from a Chinese herb root in patients with polycystic ovary syndrome (PCOS). METHODS: Women with premature ovarian failure (POF) were assigned to the obese group (body mass index [BMI] ≥24 kg/m2 and waist hip ratio [WHR] >0.85) or non-obese group (group 3, n = 21). Obese patients were further randomly assigned to the obese treatment group (group 1, n = 15) and obese control group (group 1, n = 15). All patients received standard treatment (Diane-35, 1 tablet/d, orally, plus metformin, 1.5 g/d, orally). In addition to the standard modality, patients in group 1 and group 3 also orally received 150 mg/d of puerarin tablets for 3 months. Venous blood was drawn before and after treatment. Then, the metabolic and antioxidant biomarkers were measured. The normality of distribution of the data was tested using the Kolmogorov-Smirnov method. The baseline characteristics were analyzed using one-factor analysis of variance (ANOVA), and post-hoc was performed using the least significance difference (LSD)-t test. RESULTS: Significantly improved blood levels of sex hormone binding globulin (SHBG) and superoxide dismutase (SOD) were observed in patients who received the additional treatment of puerarin, regardless of their lean or obese status, while these were not observed in patients who did not receive puerarin. Furthermore, obese patients with PCOS had significantly lower systolic blood pressure, total cholesterol, and testosterone blood levels, when compared with before treatment. CONCLUSION: The addition of puerarin to the present treatment protocol can be considered for the management of metabolic disorders and hyperandrogenism in PCOS patients.

Polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) in sediments of Liaohe River: levels, spatial and temporal distribution, possible sources, and inventory.

Spatial and seasonal variations of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) in the sediment of Liaohe River were investigated in this study. A total of 29 surface sediment samples were collected in May and September in 2013. Results showed that levels of the two classes of compounds were higher in September than in May. The total concentration of PBDEs (∑8PBDEs) ranged from 0.30 to 5.09 ng g(-1) in May and from 0.17 to 13.73 ng g(-1) in September, respectively, and BDE 209 was the dominant compound. The total concentration of PCBs (∑33PCBs) was in the range of 4.92-76.86 and 11.69-179.61 ng g(-1) in May and September, respectively, with tri- and tetra-CBs dominated in the total PCBs in the sediments. According to the congener profiles and the principal component analysis, the major sources of PCBs and PBDEs in sediments of Liaohe River were from the usage of commercial products and industrial activities, and the degradation of high brominated BDEs also contributed to the current PBDEs in the sediments. The mass inventories of PBDEs and PCBs in the sediments of Liaohe River were 1.74 and 21.96 t, respectively, indicating that Liaohe River sediments may act as the potential sources of PBDEs and PCBs to the downstream coastal areas.
