Objective To evaluate the construction status of a healthy city in central China, and clarify the weak links and construction results in the construction of a healthy city, and to provide a basis for the relevant government departments to issue policies. Methods Healthy city construction evaluation system in this city was established according to the National Healthy City Construction Evaluation System (2018) of the National Healthy City Evaluation Office Forty-two sets of health city construction index data in 2017-2018 were collected and analyzed. The single index was calculated according to the Guidance Manual for Filling in the Healthy City Evaluation Data, and the single index data was then standardized. The Delphi method was used to consult the weights of the three-level index. Finally, the sub-index and the total index of each dimension of the city's healthy city construction were calculated based on the health index method. Results The results of the 2017-2018 healthy city construction evaluation showed that 35 of the 42 indexes participated in the evaluation, and the total-indices of the two years were 77.71 and 79.95, respectively. The two-year sub-indices of the five dimensions of health service, health culture, health environment, healthy population, and healthy society were 17.17 and 18.32, 11.39 and 12.85, 19.21 and 17.94, 13.81 and 13.81, 16.12 and 17.04, respectively. Except for the decline in the health environment dimension, the other four sub-indices and the total healthy city index showed an upward trend year by year. In the past two years, the comprehensive proportions of the corresponding weight of the five dimensions sub-indices were 95.58% in health culture, 95.47% in health service, 73.99% in health environment, 73.27% in healthy society, and 69.52% in healthy people. Conclusion After the construction of national healthy city and the pilot construction of national healthy city, a city in central China achieved its first results in five dimensions of healthy city. In 2018, among the 35 indexes participated in the evaluation in this city, 30 were positive, and 26 were better than the national/ provincial target value. However, some construction indices were still far from the standard values. The development of the five dimensions was unbalanced, and there were weak links in different degrees.

Objective To investigate the prevalence of common diseases among primary and secondary school students in Yichang City from 2019 to 2022, and to provide a scientific basis for formulating effective intervention measures in the future. Methods By random cluster sampling , 7 schools in urban areas and 5 schools in suburban counties were selected to screen common diseases such as myopia, dental caries, obesity and abnormal spinal curvature. Descriptive epidemiological methods were employed for statistical analysis. Results A total of 17 023 primary and secondary school students were screened from 2019 to 2022. The overall detection rate of common diseases from high to low was myopia (54.12%), caries (36.75%), overweight (15.17%), obesity (11.88%), malnutrition (5.80%), and abnormal spinal curvature (3.49%). The detection rates of myopia and abnormal curvature of the spine showed an increasing trend with years and school stages, while the detection rates of malnutrition and dental caries showed a decreasing trend with years and school stages. The detection rates of overweight and obesity showed no trend difference with years, and the detection rates of obesity showed a decreasing trend with school stages. The rates of myopia, overweight and obesity were higher in urban areas than those in suburban counties, and the rate of dental caries was higher in suburban counties than that in urban areas. The prevalence of overweight, obesity, and malnutrition in boys was higher than that in girls. The prevalence of myopia and dental caries in girls was higher than that in boys. The above differences were statistically significant (all P<0.05). Conclusion Myopia, dental caries, obesity, and abnormal curvature of the spine are the current focus of the prevention and treatment of common diseases in students. There are great differences between different regions, school stages, and genders. The ^“tripartite linkage^” of schools, families, and communities should be achieved with the joint efforts of the education and health departments to actively take targeted intervention measures to reduce the prevalence.

【Objective】 To explore the prediction of clinical red blood cells (RBCs) consumption under major public health emergencies, so as to provide scientific basis for blood collection and blood inventory management. 【Methods】 The clinical consumption of different types of RBCs in Yichang from 2001 to 2017 was analyzed and modeled using the recurrent neural network (RNN) model, and the clinical RBCs consumption between January 2019 and December 2021(36 months) were scientifically predicted. 【Results】 The RNN model showed good prediction performance. The root mean square errors (RMSE) of RNN prediction values of A, B, O, AB type of RBCs were 156.7, 133.4, 204.2 and 51.3, respectively, with the average relative errors (MRE) at 6.4%, 6.6%, 8.5% and 7.1%, respectively. The model predicted the changing trend of RBCs consumption during the first round of COVID-19 outbreak (January to June, 2020) and forecasted the lowest level of consumption in February 2020 and a subsequent recovery in growth. The prediction of RBCs consumption during the second round of COVID-19 pandemic (January to June, 2021) was of high accuracy. For example, the relative errors of RNN models for A type RBCs consumption were 5.2% in Feb 2021 (the lowest level, 1 621.5 U) and 2.5% in May 2021 (the highest level, 2 397.0 U). 【Conclusion】 The artificial intelligence RNN model can predict clinical RBCs consumption well under major public health emergencies.

Objective To investigate the effect of daphnetin on superoxide dismutase (SOD) activity and DNA synthesis in P. falciparum in vitro. Methods The effect of daphnetin, daphnetin-Fe complex and desferrioxamine B on SOD activity of P. falciparum (P. f) FOCI in vitro was determined with a SOD test-kit. The level of DNA synthesis of P. f synchronized cultured in vitro at various developmental stages after treatment of daphnetin or desferrioxamine B was assayed by fluorescein Hoechest 33258. Results The total SOD activity decreased by 60% after daphnetin treatment while it only decreased by 22% if treated with desferrioxamine B. No effect on SOD activity of P. f treated with daphnetin-Fe complex was observed. The level of DNA synthesis of P. f trophozoites in synchronized in vitro culture was significantly lower than that of the control. Conclusion Daphnetin lowered SOD activity and decreased DNA synthesis of P. f in vitro.

Objective To investigate the characteristics and influencing factors of mental health status of permanent residents in Yichang, Hubei Province. Methods A total of 9 576 permanent residents aged 18 years and older from Yichang City were selected by a multistage random sampling method between June and October 2022. The PHQ-9 was used to assess the residents’ depressive symptoms, the GAD-7 was used to assess their anxiety symptoms, the ISI was used to assess their insomnia status, and the PCL-5 was used to assess their stress status. The influence factors of depression and anxiety were analyzed using χ2 test and logistic regression. Results A total of 9 122 valid questionnaires were completed. The detection rate of depression, anxiety, insomnia, and stress symptoms were 29.98%, 19.03%, 11.97% and 1.58%, respectively. Gender, education level, monthly family income, self-rated health status, mental health literacy level, total GAD-7 score, total ISI score, and total PCL-5 score were the main factors that caused residents' anxiety symptoms, while gender, education level, self-rated health status, total PHQ-9 score, total ISI score, and total PCL-5 score were the main factors that caused residents' anxiety symptoms. Conclusion The prevalence of depression and anxiety is high among the permanent residents in Yichang, while the situation of insomnia and stress is relatively good. Measures such as improving the level of mental health literacy can be taken to improve mental health level of residents in Yichang.

Objective To investigate the therapeutic effect of a combination of artemether and daphnetin against Plasmodium berghei ANKA strain in mice. Methods Groups of P. berghei infected mice were treated with various oral doses of artemether and daphnetin according to “4-day suppress assay”. Thin blood smears were made on the fifth day after inoculation of parasites and the parasitemia reduction rate was calculated. The ED 50 values obtained were plotted on isobolograms. A combined action of artemether and daphnetin was assessed. Results Artemether 0.4mg/(kg?d)?4d exhibited no detectable antimalarial effect, while artemether 0.4mg/(kg?d)?4d combined with daphnetin 7.7 mg/kg.d?4d showed potent antiparasile efficacy. The ED 50s of artemether in combination with daphnetin were lower than that of single artemether or daphnetin. The R-values were higher than 0.4, but lower than 2.7. Conclusion The combination of artemether with daphnetin showed an additive antiparasile effect.

Objective:To investigate the effect of the integrin-linked kinase(ILK) small interfering RNA(siRNA) on prostate cancer in nude mice by orthotopic injection of human cell line DU145.Methods:The cultured human cell line DU145 was knocked down for ILK using a siRNA.Cellular ILK expression was quantified by RT-PCR and Western blot analysis.Moreover,cell attachment,invasiveness and microfilament dynamics assays were performed.Furthermore,the impact of the ILK siRNA on the prostate cancer was tested using a nude mice model in which prostate cancer was induced by orthotopic injection of human prostate cancer cell line DU145.Gross tumor volume of prostate in nude mice,cell differentiation,the state of apoptosis and proliferation were tested after 5 weeks of injection.Results:The expression of ILK was suppressed significantly by siRNA,cellular mRNA and protein of ILK decreased 87% and 81% separately.The knockdown of ILK also induced the attachment and invasiveness of DU145 cell growing down.The tumor volume,cell differentiation,apoptosis index and proliferation index of prostate in nude mice of ILK siRNA orthotopic injection model were significantly smaller,better,increased and decreased separately than those in control group.Conclusion:Targeting inhibition of ILK not only decreases attachment and invasiveness of human DU145 cells,but also suppresses the growth and development of prostate cancer of orthotopic injection human DU145 cell line model in nude mice.

Objective To investigate the pathogenesis,clinical characteristics,diagnosis and treatment of Ceftriaxone-associated urinary tract and biliary pseudolithiasis in children.Methods A 6-year-old boy was treated in our hospital in March 2011.The initial diagnosis was acute suppurative tonsillitis.Ceftriaxone was administered intravenously at a dose of 3 g/d [ 117 mg/( kg · d) ]for three days.After that the boy complained of bilateral abdominal pain and nausea.Abdominal sonogram obtained after cessation of ceftriaxone treatment revealed urinary tract and gallbladder stone and hydronephrosis.After cessation of ceftriaxone treatment and intubation tube into the ureters by cystoscope,symptoms gradually disappeared and renal function recovered.Results After cessation of ceftriaxone treatment,symptoms gradually disappeared,with urinary tract CT scan normal after 10 days.Urinary tract and gallbladder sonograms were found to be normal 22 days after diagnosis without specific treatment.Followed up for 1 month,no recurrence of stone was observed.Conclusions Ceftriaxone-associated urinary tract and biliary pseudolithiasis in children is rare.These complications generally resolve spontaneously with cessation of the ceftriaxone therapy.Physicians should be aware of these complications so as to avoid unnecessary therapeutic procedures.

Objective To investigate the effect of LncRNA WT1-AS on the invasion and migration of triple-negative breast cancer MDA-MB-231 cells. Methods qRT-PCR was used to detect the expression of WT1-AS and the efficiency of gene silencing in MDA-MB-231 cells. Transwell invasion test and scratch test were used to detect the invasion and migration of MDA-MB-231 cells; Western blot was used to detect the expression of E-cadherin, N-cadherin, Vimentin and Snail in MDA-MB-231 cells. Results Compared with normal human mammary epithelial cells, the expression of WT1-AS in MDA-MB-231, MDA-MB-453 and MDA-MB-468 cells were significantly up-regulated. Knockdown of WT1-AS significantly reduced the invasion and migration abilities of MDA-MB-231 cells, the expression of E-cadherin was increased but N-cadherin, Vimentin and Snail expression were decreased. Conclusion WT1-AS could promote the invasion and migration of triple-negative breast cancer cells MDA-MB-231 via regulating epithelial-mesenchymal transition.
