Objective:To analyze the prevalence and risk factors of blindness and moderate to severe visual impairment among Han and Kazakh residents aged 50 years and older in Tacheng City, Xinjiang Uygur Autonomous Region.Methods:This study is a cross-sectional survey conducted using cluster random sampling from October 2015 to June 2018 in Emin County, Tacheng City, Xinjiang Uygur Autonomous Region. The study included individuals aged 50 years and older to survey blindness and moderate to severe visual impairment. Ophthalmological examinations combined with questionnaires were conducted to gather basic information. The data collected from the questionnaires included general demographic information and health conditions. The results of the eye examinations were used to diagnose a total of 12 risk factors including cataracts, glaucoma, pterygium, suspected glaucoma, glaucoma, and refractive errors. These risk factors were analyzed in relation to blindness and moderate to severe visual impairment. Univariate analysis was conducted first, followed by logistic regression to identify the significant factors.Results:A total of 2 114 patients were included in the final analysis, among which the prevalence of moderate to severe visual impairment was 18.54% (392/2 114), and the prevalence of blindness was 2.74% (58/2 114). Univariate analysis showed that blindness and moderate to severe visual impairment were associated with age ( χ2 = 32.97, P < 0.05), hypertension ( χ2 = 3.48, P < 0.05), age-related cataract ( χ2 = 17.43, P < 0.05), glaucoma ( χ2 = 3.90, P < 0.05), macular degeneration ( χ2 = 16.04, P < 0.05), diabetes ( χ2 = 3.09, P < 0.05), pterygium ( χ2 = 2.57, P < 0.05), and fundus arteriosclerosis ( χ2 = 2.31, P < 0.05). Multivariate logistic regression analysis indicated that moderate to severe visual impairment was correlated with age (50 to < 60 years: OR = 2.91, 95% CI: 0.44-13.45; 60 to < 70 years: OR = 3.52, 95% CI: 0.73-8.77; 70 to < 80 years: OR = 4.31, 95% CI: 0.85-8.96), ethnicity ( OR = 4.45, 95% CI: 0.56-5.95), sex ( OR = 0.47, 95% CI: 0.34-0.64), age-related cataract ( OR = 1.67, 95% CI: 1.05-2.65), glaucoma ( OR = 2.97, 95% CI: 1.67-5.30), and coronary heart disease ( OR = 2.56, P < 0.05). Blindness was correlated with age (70-79 years: OR = 1.54, 95% CI: 1.12-2.11), sex ( OR = 0.67, 95% CI: 0.34-0.64), glaucoma ( OR = 1.65, 95% CI: 0.42-6.49), diabetes ( OR = 2.05, 95% CI: 1.35-3.09), and coronary heart disease ( OR = 1.92, 95% CI: 1.07-3.43). Among these, age (70-79 years), glaucoma, diabetes, and coronary heart disease were identified as risk factors for blindness, while sex was observed as a protective factor against blindness in this region. Based on univariate and multivariate analyses as well as clinical practice, it was concluded that age (50 to < 60 years: OR = 4.42, 95% CI: 1.31-14.92; 60 to < 70 years: OR = 4.49, 95% CI: 1.70-11.84; 70 to < 80 years: OR = 3.19, 95% CI: 1.29-7.87), age-related cataract ( OR = 1.67, 95% CI: 1.05-2.65), and glaucoma ( OR = 2.97, 95% CI: 1.67-5.30) were identified as significant risk factors for moderate to severe visual impairment. Glaucoma ( OR = 1.65, 95% CI: 0.42-6.49) and diabetes ( OR = 2.05, 95% CI: 1.35-3.09) were identified as the main risk factors for blindness in this region (both P < 0.05). Conclusions:In Tacheng City, Xinjiang Uygur Autonomous Region, the prevalence rates of moderate to severe visual impairment and blindness among Han and Kazakh residents are relatively high. Age-related cataracts and glaucoma are the primary causes, while age and diabetes are the main risk factors.

Objective:To explore the protective effects and mechanisms of an indole-3-acetaldehyde (I3A)-loaded inulin-based hydrogel against radiation-induced intestinal injury.Methods:The gelation properties and injectability of the I3A-loaded inulin-based hydrogel were detected using a rheometer, and its biocompatibility was assessed via a CCK-8 assay. Eighteen C57BL/6 mice (aged: 6-8 weeks) were stratified by body weight and randomly assigned into three groups with 6 mice in each group: blank control, irradiation-only, and irradiation+ hydrogel protection. Abdominal irradiation was administered using 137Cs γ-rays at 17 Gy. The irradiation+ hydrogel protection group received 200 μl/day of I3A-loaded inulin-based hydrogel for two days before and 2-3 days after irradiation. Meanwhile, the irradiation-only group was treated with an equivalent volume of sterile water via gavage. The mice were euthanized four days post-irradiation, and their intestinal tissues were harvested. Hematoxylin-eosin (HE) staining, Ki67 immunohistochemistry, and TUNEL immunofluorescence were performed to assess histopathological damage, epithelial cell proliferation, and apoptosis, respectively. Quantitative real-time PCR (qRT-PCR) was employed to measure mRNA levels of inflammatory and antioxidant factors. Gut microbiota composition was analyzed via 16S rRNA sequencing. Results:The test results of the rheometer confirmed successful hydrogel formation. CCK-8 assays demonstrated excellent biocompatibility. Compared with the irradiation-only group, the irradiation+ hydrogel protection group exhibited preserved intestinal histoarchitecture, a 1.5-fold increase in intestinal cell proliferation ( t = 8.35, P < 0.05), and a 2-fold reduction in radiation-induced apoptosis ( t = 7.94, P < 0.05). Moreover, the hydrogel group showed significantly elevated expression of the anti-inflammatory cytokine IL-10 and antioxidant factors NRF-2 and HO-1 ( t = 3.16, 24.83, 5.92, P < 0.05), alongside reduced levels of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α ( t = 5.15, 3.82, 3.83, P < 0.05). Gut microbiota analysis revealed significant modulation in microbial composition and abundance in the hydrogel group. Conclusions:The I3A-loaded inulin-based hydrogel can significantly promote intestinal cell proliferation, reduce radiation-induced apoptosis, and enhance both anti-inflammatory and antioxidant responses. In addition, it regulates gut microbiota composition and abundance, protecting against radiation-induced intestinal injury.

Objective To explore the factors affecting the success rate of operation in patients with end-stage renal disease by analyzing and comparing the differences of patients'basic conditions and clinical laboratory data.Methods A total of 107 patients who underwent forearm autogenous arteriovenous fistula surgery in Nujiang Lisu Autonomous Prefecture People's Hospital from January 2021 to August 2024 were selected and divided into AVF failure group and AVF success group according to whether internal fistula occluded during the operation or within 1 week after the operation.The basic data and clinical laboratory data of enrolled patients were collected.Correlation statistical methods were used to compare whether there were differences between the two indexes.Results Univariate analysis showed that there were statistically significant differences between the two groups in smoking history,diabetes history,nephritic syndrome history,gender,preoperative blood pressure,hemoglobin,low density lipoprotein and total cholesterol(P<0.05).However,There was no significant difference between the two in history,age,white blood cell count,neutrophil count,lymphocyte count,monocyte count,platelet,creatinine,urea nitrogen,triglyceride,blood calcium,blood phosphorus,calcium-phosphorus product,fibrinogen,D-dimer and albumin(P>0.05).Binary Logistic regression analysis showed that gender,diabetes history,nephritic syndrome history,preoperative blood pressure,hemoglobin and low-density lipoprotein were independent risk factors for AVF initiation failure(P<0.05).Conclusion Female patients,history of diabetes mellitus,history of nephrotic syndrome,low hemoglobin,elevated low-density lipoprotein,and poor blood pressure control are independent factors affecting the failure of AVF initiation.

Objectives:To develop modified prehospital stroke scales and to evaluate their predictive value for in-hospital acute large vessel occlusion (LVO) stroke.Methods:Patients admitted to Dongtai People's Hospital due to non-stroke-related diseases and activated the in-hospital stroke green channel due to suspected stroke symptoms during hospitalization from January 2015 to December 2022 were included retrospectively. According to the final imaging diagnosis, they were divided into LVO group and non-LVO group. The five prehospital stroke scales included Field Assessment Stroke Triage for Emergency Destination (FAST-ED), Rapid Arterial Occlusion Evaluation (RACE), Los Angeles Motor Scale (LAMS), Cincinnati Prehospital Stroke Severity Scale (CPSSS), and Prehospital Acute Stroke Severity Scale (PASS). Multivariate logistic regression analysis was used to determine independent predictive factors of LVO in patients with in-hospital stroke, and incorporating them into the prehospital stroke scale to develop modified scales. The receiver operating characteristic (ROC) curve was used to evaluate the predictive performance of the modified scales. Results:A total of 174 patients with in-hospital stroke were enrolled, including 92 males (52.9%), aged 65.7±11.9 years. Fifty-four patients (31.0%) had LVO, and 59 (33.9%) had a surgical history within 3 days before the onset of stroke, mainly cardiopulmonary surgeries. Multivariate logistic regression analysis showed that atrial fibrillation (odds ratio 2.940, 95% confidence interval 1.387-6.230; P=0.005) and recent history of cardiopulmonary surgery (odds ratio 6.861, 95% confidence interval 2.437-11.315; P<0.001) were the independent predictive factors of LVO in patients with in-hospital stroke. According to the β coefficient and ROC curve, they were assigned a score of 1 and included in the prehospital stroke scale. The area under the curve of the modified scale for predicting LVO (mRACE: 0.917; mFAST-ED: 0.865; mPASS: 0.859; mCPSSS: 0.853; mLAMS: 0.907) was significantly higher than the corresponding original scale (RACE: 0.888; FAST-ED: 0.820; PASS: 0.786; CPSSS: 0.810; LAMS: 0.859) (all P<0.05). Conclusion:The modified scales based on the prehospital stroke scales can significantly improve the predictive value of in-hospital acute LVO stroke compared to the original prehospital stroke scales.

Objective To build the early predictive model for chronic kidney disease(CKD)in hypertension and diabetes patients in the community.Methods The CKD patients were recruited from 4 health care centers in 4 urban areas in Kunming.The control group was residents without hypertension and diabetes(n = 1267).The disease group was residents with hypertension and/or diabetes(n = 566).The questionnaire survey,physical examination,laboratory testing,and 5 SNPs gene types in the PVT1 gene.The risk factors,which were filtered with logistics regression,were used to build predictive models.Four machine learning algorithms were built:support vector machine(SVM),random forest(RF),Na?ve Bayes(NB),and artificial neural network(ANN)models.Results Thirteen indicators included in the final diagnostic model:age,disease type,ethnicity,blood urea nitrogen,creatinine,eGFR from MDRD,ACR,eGFR from EPI2009,PAM13 score,sleep quality survey,staying-up late,PVT1 SNP rs11993333 and rs2720659.The accuracy,specificity,Kappa value,AUC of ROC,and PRC of ANN are greater than those of the other 3 models.The sensitivity of RF is the highest among 4 types of machine learning.Conclusions The ANN predictive model has a good ability of efficiency and classification to predict CKD with hypertension and/or diabetes patients in the community.

Hyperkalemia is one of the common ion metabolism disorders in clinical practice. Hyperkalemia is defined as serum potassium higher than 5.0 mmol/L according to the guidelines at home and abroad. Acute severe hyperkalemia can cause serious consequences, such as flaccid paralysis, fatal arrhythmia, and even cardiac arrest. The use of renin-angiotensin- aldosterone system inhibitors, β-blockers and diuretics, low-sodium and high-potassium diets, and the presence of related comorbidities increase the occurrence of hyperkalemia. Hyperkalemia risk exist in all clinical departments, but there is a lack of a standardization in the management of multi- department cooperation in hospital. Therefore, a number of domestic nephrology and cardiology department experts have discussed a management model for multi-department cooperation in hyperkalemia, formulating the management standard on hospital evaluation, early warning, diagnosis and treatment, and process. This can promote each department to more effectively participate in nosocomial hyperkalemia diagnosis and treatment, as well as the long-term management of chronic hyperkalemia, improving the quality of hyperkalemia management in hospital.

Objective:To discuss the effect of apolipoprotein C1(APOC1)expression on the proliferation and apoptosis of the hepatocellular carcinoma cells,and to preliminarily clarify the related molecular mechanism.Methods:The expression level of APOC1 mRNA in hepatocellular carcinoma tissue and its relationship with the prognosis of the patient were analyzed by The Cancer Genome Atlas(TCGA)Database;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of APOC1 mRNA in different hepatocellular carcinoma cells;the human liver cancer HepG2 cells with low APOC1 expression were selected as the subjects.The HepG2 cells were transfected with pcDNA3.1-APOC1 plasmid to over-express APOC1(APOC1 over-expression group),and the HepG2 cells transfected with empty vector pcDNA3.1 were regarded as control group.MTS assay and 5-ethynyl-2'-deoxyuridine(EdU)staining were used to detect the proliferative activities and proliferation rates of the cells in two groups;Transwell chamber assay was used to detect the numbers of migration cells in two groups;flow cytometry and TUNEL assay were used to detect the percentages of the cells at different cell cycles and apoptotic rates in two groups;Western blotting method was used to detect the expression levels of extracellular regulated protein kinase(ERK),phosphorylated ERK(p-ERK),protein kinase B(AKT),phosphorylated AKT(p-AKT),B-cell lymphoma-2(Bcl-2),and cleaved cysteinyl aspartate specific proteinase-3(cleaved caspase-3)proteins in the cells in two groups.Results:The TCGA Database results showed that the expression level of APOC1 mRNA in hepatocellular carcinoma tissue was lower than that in normal liver tissue(P<0.05),and the patients with low expression of APOC1 mRNA had poor prognosis.The RT-qPCR results showed that the expression level of APOC1 mRNA in the HepG2 cells was the lowest,and the HepG2 cells were chosen for the subsequent research.Compared with control group,the proliferative activity and proliferation rate of the cells in APOC1 over-expression group were decreased(P<0.05 or P<0.01),the number of migration cells was decreased(P<0.01),and the percentage of the cells at S phase and the apoptotic rate were significantly increased(P<0.01).Compared with control group,the expression levels of p-ERK,p-AKT,and Bcl-2 proteins in the cells in APOC1 over-expression group were significantly decreased(P<0.05),and the expression level of cleaved caspase-3 protein was increased(P<0.01).Conclusion:High expression of APOC1 can inhibit the proliferation of the human liver cancer HepG2 cells and induce the apoptosis,and its mechanism may be related to inhibition of the expressions of p-ERK,p-AKT,Bcl-2 proteins and promotion of the expression of cleaved caspase-3 protein.
