ABSTRACT
Objective@# To investigate the level of mental health literacy among residents in Jiaxing City, Zhejiang Province, so as to provide insights into implementation of mental health education and improvements of the quality of mental health services. @*Methods@#A total of 2 248 permanent residents at ages of 18 years and older were sampled using a multi-stage stratified random sampling method from 3 streets (townships) in Jiaxing City. Residents' demographics were collected using self-designed questionnaires, and the mental health literacy was investigated using the Mental Health Literacy Questionnaire. Factors affecting the achievement of the target of mental health literacy were identified among residents using a multivariable logistic regression model. @*Results@#A total of 2 248 questionnaires were allocated and 2 172 valid questionnaires were recovered, with an effective recovery rate of 96.62%. The respondents included 1 075 men (49.49%) and 1 097 women (50.51%). There were 623 respondents that met the target of the mental health literacy (28.68%). Multivariable logistic regression analysis showed a higher possibility of achieving the target of mental health literacy levels among women than among men (OR=1.282, 95%CI: 1.047-1.570), among unmarried residents (OR=1.685, 95%CI: 1.018-2.788) than among married residents, among residents with educational levels of junior high school (OR=1.689, 95%CI: 1.168-2.441), high school/vocational high school/technical secondary school (OR=2.420, 95%CI: 1.601-3.658) and college or above (OR=3.543, 95%CI: 2.252-5.574) than among residents with an educational level of primary and below, among students (OR=2.572, 95%CI: 1.013-6.527), medical personnel (OR=3.330, 95%CI: 2.029-5.467), teachers (OR=2.909, 95%CI: 1.202-7.040), freelance/self-employed staff (OR=1.519, 95%CI: 1.100-2.098) and other professional technical personnel (OR=1.529, 95%CI: 1.012-2.310) than among workers.@* Conclusions @#The proportion of mental health literacy levels meeting the target is high among residents in Jiaxing City, and gender, educational level, occupation and marital status are factors affecting mental health literacy levels.
ABSTRACT
Vitamin D deficiency is identified as a risk factor for the occurrence and recurrence of ovarian cancer.Galectin-3 (Gal-3) participates in many physiological and pathological processes. In present study, serumvitamin D level was detected using chemiluminescence enzyme immunoassay. Gal-3 expression wasexamined using real-time polymerase chain reaction (PCR), Western blot and immunocytochemistry analysis. SKOV3 cells viability was assessed by the water-soluble tetrazolium salt (WST-1) assay, the migrationof SKOV3 cells was detected using transwell assay, and the proliferation of SKOV3 cells was measured by3H-thymidine incorporation (3H-TdR). Our study demonstrated that vitamin D levels were lower in 40ovarian cancer patients: vitamin D deficiency is closely related to the pathogenesis of ovarian cancer.Treatment with vitamin D reduced the migration and proliferation of ovarian cancer cells. Gal-3 wasoverexpressed in ovarian cancer, which could induce the viability, migration and proliferation ability ofovarian cancer cells, and these effects were abrogated by vitamin D downregulating the expression of Gal-3gene. Therefore, our results support that vitamin D may suppress Gal-3-induced viability, migration andproliferation ability of ovarian cancer cells, which suggests that the use of vitamin D may have beneficialeffects in preventing and treating ovarian cancer.
ABSTRACT
ABSTRACT Antiviral drug resistance is the most important factor contributing to treatment failure using nucleos(t)ide analogs such as lamivudine for chronic infection with hepatitis B virus (HBV). Development of a system supporting efficient replication of clinically resistant HBV strains is imperative, and new antiviral drugs are needed urgently to prevent selection of drug-resistant HBV mutants. A novel fluorinated cytidine analog, NCC (N-cyclopropyl-4′-azido-2′-deoxy-2′-fluoro-β-d-cytidine), was recently shown to strongly inhibit human HBV in vitro and in vivo. This study was designed to evaluate the antiviral activity of NCC against lamivudine-resistant HBV. We generated a stable cell line encoding the major pattern of lamivudine-resistant mutations rtL180M/M204V and designated it "HepG2.RL1". Immuno-transmission electron microscopic examination and enzyme-linked immunosorbent assay were used to detect secretion of HBV-specific particles and antigens. Quantification of extracellular DNA and intracellular DNA of HepG2.RL1 cells by quantitative real-time polymerase chain reaction revealed >625-fold and >5556-fold increases in the 50% inhibitory concentration of lamivudine, respectively, compared with that for the wild-type virus. The results showed that NCC inhibited DNA replication and HBeAg production in wild-type or lamivudine-resistant HBV in a dose-dependent manner. In conclusion, screening for antiviral compounds active against lamivudine-resistant HBV can be carried out with relative ease using hepG2.RL1 cells. NCC is a potential antiviral agent against wild-type HBV and clinical lamivudine-resistant HBV and deserves evaluation for the treatment of HBV infection.
