Objective: To evaluate the effectiveness for the construction of "mosquito-free village" in Xuejia Village, Pujiang County, Zhejiang Province, so as to provide the guidance for the construction of "mosquito-free village" in other rural areas. Methods: Density of adult mosquitoes in Xuejia Village was investigated using light trap method and density of larval mosquitoes was investigated using larval straw method from April to November each year. Totally 30 households of villagers were randomly selected, and their awareness rates of mosquito control knowledge, mosquito control behavior forming rates and satisfaction rates were surveyed through questionnaires. Investment during construction (from August 2016 to December 2018) and maintenance period (from 2019 to 2023) of "mosquito-free village" were investigated through data review and interviews. Long-term effects of "mosquito-free village" construction in Xuejia Village were evaluated in terms of mosquito density from 2016 to 2023, effectiveness of health education for villagers, satisfaction and investment. Results: Compared with the year 2016, the densities of adult and larval mosquitoes in Xuejia Village were significantly decreased from 2017 to 2023. The average monthly density of adult mosquitoes in 2023 decreased by 98.34%, and the average monthly 100 household index of larval mosquitoes decreased by 98.45% compared to 2016. The average monthly density of adult mosquitoes from 2019 to 2023 was less than or equal to one mosquito per light trap in a night, and the average monthly 100 household index of larval mosquitoes was less than or equal to five places per 100 households. The awareness rate of mosquito control knowledge was 93.33%, the behavior forming rate was 86.67%, and the satisfaction rate was 90.00%. By December 2023, the total investment during construction and maintenance period was 450 thousand Yuan, with an average annual investment of 60.7 thousand Yuan and average annual investment of 206.61 Yuan per household. The average annual investment during maintenance period was 36.2 thousand Yuan, and the average annual investment per household was 109.70 Yuan. Conclusion The mosquito density, effectiveness of health education for villagers and satisfaction of "mosquito-free village" in Xuejia Village all meet the evaluation criteria of "mosquito-free village", and the investment is reasonable, making it suitable for promotion to other rural areas.

Objective:To analyze the application value of non-invasive inflammation diagnosis model in the diagnosis of liver fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) combined with hepatitis B virus (HBV) infection.Methods:A total of 98 patients with NAFLD complicated with HBV infection admitted to some coastal China Coast Guard Hospital of People′s Armed Police from June 2019 to October 2021 were selected. Their liver stiffness (LSM), aspartate aminotransferase to platelet ratio (APRI), γ-glutamyltranspeptidase to platelet ratio (GPR), and fibrosis index based on factor 4 (FIB-4) were measured, The receiver operating characteristic (ROC) curve was used to analyze its clinical diagnostic efficacy for liver fibrosis caused by NAFLD combined with HBV infection.Results:Among 98 patients, there were 7 cases in S0 stage, 47 cases in S1 stage, 21 cases in S2 stage, 14 cases in S3 stage, and 9 cases in S4 stage; Including 35 cases of obvious liver fibrosis and 9 cases of cirrhosis.

Results: Totally 5 435 deaths occurred due to cancer in Ouhai District from 2013 to 2020, and the crude and standardized mortality rates were 154.10/105 and 119.41/105, respectively. The crude mortality of cancer was higher in men than in women ( 196.26/105 and 111.09/105; χ2=415.623, P<0.001 ). The standardized mortality of cancer among whole populations, the crude mortality in men and the standardized mortality in men showed a tendency towards a reduction ( P<0.05 ), with APC of -3.25%, -2.18% and -4.78%, respectively. The crude mortality of cancer showed an upward trend with age ( χ2trend=9 260.583, P<0.001 ). Lung cancer, liver cancer, stomach cancer, colorectal cancer and esophagus cancer were the five leading causes of cancer-related mortality, which accounted for 66.68% of all cancer mortality. Liver cancer, lung cancer, stomach cancer, colorectal cancer and brain cancer were the five leading causes of life lost, with YPLL of 11 191.50, 8 231.00, 6 000.00, 3 892.00 and 2 693.50 person-years, respectively. Leukemia was the primary cause of AYLL ( 25.17 years per person ). Conclusions Both the standardized mortality and the life lost due to cancer showed a tendency towards a reduction in Ouhai District from 2013 to 2020, and men and the elderly were high-risk populations. Lung cancer, liver cancer, stomach cancer, colorectal cancer, leukemia, brain cancer, and female breast cancer should be listed among cancers in Ouhai District prioritized for control

Objective:To analyze the clinical manifestations and signs of the first diagnosed dry eye patients, and to explore the concordance between the Chinese dry eye diagnostic criteria and the Asian dry eye diagnostic criteria.Methods:A cross-sectional multicenter study was conducted.One hundred and forty-one eyes of 141 patients who were diagnosed as dry eye for the first time were included in Xiamen Eye Center of Xiamen University, Beijing Tongren Hospital, West China Hospital of Sichuan University and Shanghai Putuo District Center Hospital from December 2016 to May 2018.All patients completed the Chinese Dry Eye Questionnaire, Ocular Surface Disease Index (OSDI) and Dry Eye-Related Quality-of-life Score Questionnaire (DEQS) to evaluate the symptoms of dry eye.Tear film breakup time (BUT), keratoconjunctival fluorescein staining, meibomian gland morphology and function examination, and Schirmer Ⅰ test were performed to evaluate dry eye signs and the association between dry eye symptoms and signs.The eyes were divided into corneal staining positive and negative group according to the presence or absence of corneal fluorescein staining, and the dry eye symptoms of the two groups were assessed by the three questionnaires.The eyes were divided into tear-deficient dry eye, evaporative dry eye, mixed dry eye and abnormal tear dynamics dry eye to compare the difference of dry eye signs among the groups.This study adhered to the Declaration of Helsinki.The study protocol complied with Chinese regulations and rules on clinical trial research and was approved by Ethics Committees of Xiamen Eye Center of Xiamen University (No.2017003), Beijing Tongren Hospital, Capital Medical University (No.TREC2016-29), West China Hospital of Sichuan University (No.2016310) and Shanghai Putuo District Center Hospital (No.PTEC-A-2016-18-1). Written informed consent was obtained from patients before entering the cohort.Results:The total score of Chinese Dry Eye Questionnaire, OSDI questionnaire and DEQS questionnaire was 12.00(7.00, 16.00), 25.00(17.50, 36.93) and 32.02(15.77, 52.34), respectively.It was found that 130 eyes (92.2%) had dryness, and 109 eyes (77.3%) had ocular fatigue and 108 eyes (76.6%) had foreign body sensation.Dryness, foreign body sensation, photophobia and poor vision were weakly positively correlated with corneal staining ( r=0.177、0.297、0.172, all at P<0.05). Pain, photophobia and poor vision were negatively correlated with tear secretion ( r=-0.178, -0.197, -0.174; all at P<0.05). It was found that 43.3% of dry eye patients had used visual display terminals.Among the 141 eyes, 75 eyes (53.2%) were with over evaporation dry eye, 43 eyes (30.5%) with mixed dry eye, 18 eyes (12.8%) with aqueous-deficient dry eye and 3 eyes (2.1%) with abnormal tear dynamics dry eyes. Conclusions:Initial diagnosis of dry eye patients is mainly mild to moderate.Dry eye signs and symptoms are correlated.Over evaporation dry eye is the most common type of dry eye.The concordance between the Chinese dry eye diagnostic criteria and the Asian Dry Eye Society diagnostic criteria reaches 97.2%.

Objective:To explore the mechanism of miR-205-5p/E2F1 signal axis in regulating the glioma U251, U87 radiotherapy resistance.Methods:X-ray gradual ascending and intermittent induction method was used to irradiate the glioma U251 cells to establish U251/TR, U87/TR radiation-resistant cell lines. Then, the morphology, migration, invasion and proliferation abilities of cells (U251/TR, U87/TR radiation-resistant cells and U251, U87 radiation-sensitive cells) were analyzed. Luciferase gene detection system and point mutation technique were employed to analyze the mechanism of miR-205-5p and E2F1 gene activity on U251 and U87 radiation-resistant cell lines.Results:Compared with the radiation-sensitive U251 cells, the radiation-resistant cells U251/TR, U87/TR showed increased proliferation activity, enhanced migration and invasion abilities and decreased apoptosis under X-ray irradiation. miR-205-5p mimics transfection could down-regulate the expression of E2F1 factor in U251/TR cells, inhibit cell proliferation, invasion and migration and increase the radiosensitivity of U251/TR cells. miR-205-5p mimics transfection combined with with E2F1 down-regulation exerted anti-tumor effect and decreased cell tolerance by suppressing the Wnt/β-catenin signaling pathway activity.Conclusions:The glioma radiation-resistant cell line U251/TR, U87/TR can be established by X-ray gradual ascending and intermittent induction method. The miR-205-5p/E2F1 signal axis exerts tumor-suppressing effect through the classical Wnt/β-catenin signaling pathway, which can be used as an therapeutic target to increase the radiosensitivity of glioma.
