In order to investigate the inhibitory effect of plasmid-mediated short hairpin RNA targeting vascular endothelial growth factor (VEGF) on the expression of VEGF mRNA in human gastric cancer cells, a plasmid vector for transcribing specific short hairpin RNA targeting VEGF (pU6-VEGF) was constructed, and then transfected into human gastric cancer cells using Lipofectamine2000. The VEGF mRNA expression level was detected by RT-PCR. RPMI1640 was used for blank control, and pSilencer 1.0-U6 empty plasmid for the negative control. Results showed the clone and sequence analysis revealed that the recombinant plasmid vector of pU6-VEGF was successfully constructed. The VEGF mRNA expression levels in blank control group, experimental group (pU6-VEGF) and negative control group (pSilencer1.0-U6) were 100%, 49% and 94%, respectively, indicating VEGF mRNA expression in the cells transfected with pU-VEGF vector was inhibited significantly as compared with blank control group and negative control group. It was concluded that the short hairpin RNA could significantly inhibit the expression of VEGF mRNA, which provided an experimental basis for treating human cancer with anti-angiogenesis.

Background Hainan Island is a tropical and subtropical area in China,with a suitable climate for fungal growth and breeding.Keratomycosis occurred frequently in this area.It is essential to analyze the causative genus and investigate the sensitive drugs prior to the clinical treatment of fungal keratitis.Objective This study attempted to analyze the fungal population of fungal corneal ulcer patients in Hainan Island of China and examine the susceptibility of antifungal drugs.Methods A series cases observational study was carried out.One hundred and seventy-four eyes of 174 fungal corneal ulcer patients were enrolled in Hainan Eye Hospital from February 2014 to May 2016 based on the diagnosis criteria in Ophthalmology.The specimens at corneal lesions were collected under the aseptic conditions,and fungus was examined by KOH based smear.Mycological culture was performed with potatodextrose agar and Sabourand's agar.The 82 cultured causative strains were identified to characterize the spectrum of the species associated with keratitis infections in Hainan Province.Susceptibilities of these causative strains to ten antifungals were determined in vitro by slip diffusion method.Results By smear microscopy,fungal hyphae and spores were found in 34 specimens of 126 patients,with the positive rate 27.0％.In 174 specimens of fungal culture,82 strains of fungi were found,with the positive rate 47.1％,and typing results revealed that the isolates were distributed among species in the fusarium (47.5％),non-spore fungus (12.2％),aspergillus (9.8％) and phoma (9.8％).Nystatin was proved to be the most effective drug to 77 strains of antifungal drug susceptibility,followed by amphotericin B and terbinafine,with the susceptibility of 88.3 ％,72.7 ％,and 71.4％,respectively.Conclusions Fusarium species,non-spore fungus,aspergillus,and phoma are common pathogenic fungi of keratomycosis around Hainan Island in China,and nystatin,amphotericin B and terbinafine are efficient in the treatment of the fungal corneal ulcer.

PURPOSE: The purposes of the study were to examine psychological distress and health-related quality of life (HRQoL) in relocated and nonrelocated survivors aged 60 years and older, and to analyze predictors for psychological distress and HRQoL in older survivors 5 years after the 2008 Sichuan earthquake. METHODS: This was a cross-sectional descriptive study with 112 relocated older survivors and 156 nonrelocated older survivors. Our study used a multistage sampling method. The measurements used in the study included self-reporting questionnaire-20, medical outcomes study 36-item short form health survey, and an instrument measuring demographic and disaster-related characteristics. Descriptive and multiple linear regression analysis were performed to determine factors that contributed to psychological distress and HRQoL. RESULTS: The prevalence of psychological distress in relocated group (20.5%) was significantly higher compared to those in nonrelocated group (4.8%). Scores for HRQoL in relocated older survivors was significantly lower than those in nonrelocated older survivors. Relocation from preearthquake residence was the most significant predictor for psychological distress and HRQoL in the total sample. Other predictors were advanced age, lower educational level, the loss of family members during the earthquake, and the presence of chronic illnesses as well as the death of a spouse after the earthquake. CONCLUSIONS: Strategies can be designed in postdisaster recovery program, particularly for older survivors at high risk for psychological distress and poor HRQoL.

Objective To study the prevalence of cigarettes and e-cigarettes, and to analyze its influencing factors among high school students in Wenzhou. Methods:A self-administered questionnaire survey was conducted among a total of 3 785students from senior high schools and vocational high schools in Wenzhou from September to November in 2020, who were selected by stratified cluster sampling. Their demographic information and the use of tobacco [including the use of cigarettes, e-cigarettes (currently smoking and smoking attempt), and the dual use of them] were asked in the questionnaire of “Global Youth Tobacco Survey”(GYTS). Proportion and rate were used to describe their demographic characteristics and smoking prevalence. Chi-square test was used to compare the difference in smoking prevalence of the high school students with selected characteristics. Multinomial logistic regression was used to analyze the influencing factors of tobacco use among the participants.Results:Among the 3 785 questionnaires, 3 740 were completed, and effective rate was 98.80%. The smoking attempt rate, current smoking rate, e-cigarette attempt rate, e-cigarette using rate, and dual using rate of the high school students in Wenzhou were 11.79% (441/3 740), 2.57% (96/3 740), 10.00% (374/3 740), 2.86% (107/3 740), 0.99% (37/3 740), respectively. Male students, vocational high school students, the students whose parents smoking showed higher smoking attempt rate, current smoking rate, e-cigarette attempt rate than female student, senior high school students and those parents who don′t smoke, respectively (all P<0.05). Best friend smoking [6.076 (2.872-12.855); 4.630 (2.656-8.071)], vocational high school [3.226 (1.877-5.546); 2.238 (1.432-3.496)] were risk factors for e-cigarette and the cigarettes use, belief that whether smoking or not does not make any difference in social activities [0.160 (0.077-0.331); 0.193 (0.096-0.387)], or smoking in social activities makes people more uncomfortable [0.037 (0.018-0.077); 0.155 (0.083-0.288)] were protective factors of e-cigarette and the cigarettes use. Additionally, passive smoking in past week [2.194 (1.129-4.262)], free tobacco products received [2.836 (1.018-7.905)], seeing smoking in campus [2.072 (1.111-3.863)] were all risk factors, while belief that smoking makes young people less attractive [0.280 (0.116-0.676)], not having been to tobacco retail outlets and unexposed to tobacco advertising or promotion [0.241 (0.123-0.473)] can protect senior middle school student away from cigarette. As to e-cigarette, boys were the risk factors [1.831 (1.100-3.050)]; as opposed to being a risk factor for cigarette use [1.942 (1.084-3.478)], rural area was a protective factor for e-cigarette use [0.639 (0.410-0.994)] among high school students in Wenzhou. Conclusions:High school students have relatively low rates of smoking cigarettes and e-cigarette in Wenzhou. Vocational students, best friend smoking are risk factors of e-cigarette and the cigarettes, beliefs that whether smoking or not does not make any difference or smoking makes people more uncomfortable in social activities are protective factors.
