RESUMO

Prenatal examination is a pivotal measure to prevent high-risk pregnancy and to ensure the safety of both mother and infant. However, pregnant women in Linzhi Prefecture in the Tibet Autonomous Region (TAR) often cannot obtain regular prenatal examinations due to limited accessibility of healthcare facilities, shortage of medical staff, and lack of medical equipment. Health education is an important approach to solve this ever-growing issue of pregnant women in rural Tibet.To evaluate the efficacy of flexible methods of health education programs on improving compliance among pregnant women from Tibet, China.In May to November of 2018, a total of 168 pregnant women receiving prenatal examination in a tertiary referral hospital in Linzhi Prefecture were recruited and randomly assigned to a control (n = 85) and intervention group (n = 83). All pregnant women were followed up until delivery. The pregnant women in the control group received regular prenatal examination and health education programs. Other than receiving routine prenatal care, participants of the interventional group also voluntarily joined the WeChat Social Messaging platform. Online resources posted by the maternity schools provided convenience and flexibility for the pregnant woman. The number of prenatal examinations was statistically significant between the 2 groups. The effect of flexible patterns of health education programs on improving the compliance of pregnant women in Tibet was assessed.The number of prenatal examinations in the intervention group was 2.646 times, which was higher than that in the control group (P < .01). Multivariate analysis demonstrated that interventional measures and ethnicity were the influencing factors of the number of prenatal examinations for pregnant women in Linzhi after the adjustment of age, history of adverse pregnancy, education level, ethnicity, multiparity, gestational complications, and medical history. The number of prenatal examinations for the pregnant Tibetan women was 0.535 times lower compared with that of the pregnant Han women (95% CI: -0.089, 1.157, P = .091).Flexible forms of health education during the antenatal period can effectively increase the compliance of pregnant women in Tibet.

RESUMO

PURPOSE: To investigate the association of DNMT3B -283T>C polymorphism with the risk of lung or gastric cancer, which was followed by a meta-analysis. METHODS: The genotyping of -283T>C was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and was confirmed by sequencing. RESULTS: The results of this case-control study showed that -283T>C was not associated with the risk of lung or gastric cancer, and further stratified analysis according to age, gender, smoking status, and alcohol status confirmed the present finding. However, data from a meta-analysis in the Asian population revealed a significant association between -283T>C and lung cancer risk in the allelic model (C vs. T: odds ratio [OR] = 1.28, 95% confidence interval [CI], 1.06-1.55, p = 0.01) and two genetic models (CC vs. TC: OR = 1.29, 95% CI, 1.04-1.59, p = 0.02; CC vs. TC + TT: OR = 1.30, 95% CI, 1.06-1.60, p = 0.01). CONCLUSIONS: These results provided evidence that the DNMT3B -283T>C polymorphism might significantly contribute to the lung cancer risk in the Asian population, but not the gastric cancer risk in the Chinese population.

RESUMO

Emodin, a major component of Rheum palmatum, has been reported to significantly protect neural tissue against apoptosis and autophagy. However, the effects and underlying mechanisms of action of emodin in muscle atrophy are still poorly defined. In this study, we investigated the protective effects and the underlying mechanisms by which emodin acts on tumor necrosis factor alpha (TNF-α)-induced apoptosis and autophagy in mouse C2C12 myoblasts. Emodin, at various concentrations, decreased TNF-α-induced apoptosis in C2C12 myoblasts, which were analyzed by Hoechst 33342 staining and annexin V/PI analysis. Emodin also inhibited the collapse of the mitochondrial membrane potential and the generation of reactive oxygen species in TNF-α-stimulated C2C12 myoblasts. Consistent with these results, the expression of Bcl-2 was increased, whereas the expression of Bax, cleaved-caspase 3 and cleaved-PARP was decreased after emodin treatment. These data demonstrate that emodin attenuated apoptosis in TNF-α-stimulated C2C12 myoblasts through mitochondrial signaling pathways. In addition, emodin inhibited autophagy in TNF-α-stimulated C2C12 myoblasts by suppressing the expression of LC3-II, Beclin-1 and Atg7. Emodin also resulted in the upregulation of the phosphorylated forms of Akt. Taken together, these results suggest that emodin inhibited apoptosis and autophagy in TNF-α-induced C2C12 myoblasts, possibly through the activation of phosphorylated Akt. Our findings suggest that emodin could be a potential therapeutic agent in the treatment of muscle atrophy.
