Objective To analyze the relationships of serum microRNA(miR)-15,miR-16,miR-17-5p,and triglyceride-glucose index(TyG)with severity and prognosis of acute ischemic stroke(AIS).Methods A total of 136 AIS patients admitted to the Shijiazhuang Hospital of Traditional Chi-nese Medicine from April 2023 to April 2024 were enrolled.Prognosis and disease severity were as-sessed using modified Rankin Scale(mRS)and National Institutes of Health Stroke Scale(NIHSS),respectively.Based on mRS scores at 3 months post-onset,patients were divided into poor prognosis group(mRS Score＞2,n=42)and good prognosis group(mRS Score ≤ 2,n=94).Serum levels of miR-15,miR-16,miR-17-5p,TyG,and NIHSS scores were compared between two groups.Pearson correlation analysis was used to evaluate associations of these biomarkers with NIHSS scores.Logistic regression was used to identify risk factors for poor prognosis,while receiver operating characteristic(ROC)curves was applied to assess the predictive value of individual and combined biomarkers.Results The poor prognosis group exhibited significantly higher serum miR-15,miR-16,miR-17-5p,TyG,and NIHSS scores than the good prognosis group(t=8.634,13.171,29.018,2.687,26.432;P＜0.05).Positive correlations were observed between these biomarkers and NIHSS scores(r=0.472,0.449,0.492,0.437;P＜0.05).Logistic regression identified miR-15[OR(95％CI):3.526(2.628 to 5.859)],miR-16[1.976(1.226 to 3.017)],miR-17-5p[1.828(1.294 to 3.428)],NIHSS score[1.787(1.105 to 2.896)],TyG[1.886(1.233 to 3.284)],and homo-cysteine[1.906(1.252 to 3.794)]as independent risk factors for poor prognosis(P＜0.05).ROC analysis demonstrated that the combined model(miR-15,miR-16,miR-17-5p,TyG,and NIHSS)achieved superior predictive performance(AUC=0.877;95％CI,0.820 to 0.948)com-pared to individual biomarkers(Z＞2.527,P＜0.05).Conclusion Elevated serum miR-15,miR-16,miR-17-5p,and TyG are closely associated with AIS severity and poor prognosis.The above indicators combined with NIHSS scores can enhance predictive accuracy for unfavorable outcomes.

Objective:To explore the clinical and genetic characteristics of a fetus diagnosed with Congenital myasthenic syndrome type 16 (CMS16).Methods:A couple who had visited Tianjin Medical University General Hospital in February 2018 due to "adverse outcome of two pregnancies" was selected as the study subject. Clinical data was gathered. Peripheral blood and amniotic fluid samples were collected and subjected to whole exome sequencing (WES). Candidate variant was verified by Sanger sequencing. Low-depth whole-genome sequencing was carried out to detect copy number variation (CNV) in the fetus.Results:The couple′s first pregnancy had resulted in a miscarriage at 27 + 5 weeks, when ultrasound had revealed pleural effusion and polyhydramnios in the fetus. Their second pregnancy was terminated at 30 + 5 weeks due to fetal hand malformations, polyhydramnios and pleural fluid. Both couple had denied family history of genetic conditions. For their third pregnancy, no CNV abnormality was detected, whilst a compound heterozygous variants, including a maternally derived c. 3172C>T (p.R1058W) and paternal c. 1431delG (p.K477fs*89) in the SCN4A gene were detected. Based on the guidelines from the American College of Medical Genetics and Genomics, the c. 3172C>T (p.R1058W) was predicted as a likely pathogenic variant (PM1+ PM2_supporting+ PP3+ PP4), whilst the c. 1431delG (p.K477fs*89) was predicted as a pathogenic variant (PVS1+ PM2_supporting+ PP4). Conclusion:The c. 3172C>T (p.R1058W) and c. 1431delG (p.K477fs*89) compound heterozygous variants of the SCN4A gene probably underlay the CMS16 in the third fetus.

Objective:To investigate the risk factors of diabetic kidney disease (DKD) in type 2 diabetes mellitus (T2DM) patients in plain-sand areas and loess hilly areas of Gansu province.Methods:A total of 1 599 T2DM patients who participated in chronic disease and risk factors monitoring and basic public health service management were selected by multi-stage stratified random sampling method in the sandy plain areas and loess hilly areas of Gansu province. Questionnaire survey, physical measurement and laboratory tests were performed. Multivariate binary logistic model was used to analyze the influencing factors.Results:The prevalence of DKD was 22.1% (174/787) among T2DM patients in the sandy plain areas and 19.1%(155/812) in the loess hilly area, respectively. Hypertension ( OR=3.022), hyperuricemia ( OR=2.114) and HbA1c≥7%( OR=2.231) were the risk factors for DKD in the plain-sand areas, and the risk of DKD increased with age. In the loess hilly areas, female sex ( OR=0.379) was the protective factor for DKD; while duration of disease≥10 years ( OR=2.476), hyperuricemia ( OR=1.907), HbA1c≥7% ( OR=1.927) were the risk factors for DKD; and the risk of DKD increased with the increase of age, and decreased with the increase of per capita monthly income. Conclusions:The prevalence of DKD and its influencing factors are different between sandy plain areas and loess hilly areas in Gansu province. The prevention and treatment of hypertension should be given more attention in sandy plain areas. In addition, the screening of DKD should be conducted among T2DM patients, particularly for those with old age, hyperuricemia and HbA1c≥7% in both areas of the province.

Objective: To investigate the CT and MR imaging features of hepatic ischemia/necrosis after hepatosplenic surgery and upper gastrointestinal hemorrhage. Methods: A total of 36 patients diagnosed with hepatic ischemia/necrosis by both medical imaging and clinical diagnosis shortly after hepatosplenic surgery and upper gastrointestinal hemorrhage were collected, including 9 patients with liver cancer resection, 5 patients with liver cancer ablation (microwave ablation/radiofrequency ablation, argon-helium knife, alcohol injection), 11 patients with spleen resection, and 11 patients with upper gastrointestinal bleeding. Conventional liver CT and / or MR plain and dynamic enhancement scan were performed to comprehensively analyze the morphology and density/signal performance of the lesions. Results: (1) Number of lesions: All cases had multiple lesions. (2) Distribution of lesions: scattered in the liver lobes, clustered or regional distribution, mainly in the periphery of the liver. (3) Size of lesions: the boundary of the nodular lesion was clear, and the single maximum diameter was 1.0-1.5 cm. It can be fused into a wedge-shaped patch or a segmental/sub-segmental large patch with a slight mass effect. (4) CT density or MR signal characteristics: CT plain scan showed slightly low density; MR plain scan showed slightly low signal on T1WI, high signal on T2WI, slightly high signal on DWI and no lipid/fat on dual phase imaging; 24 out of 36 cases (66.7%) showed no enhancement, while some lesions showed thin ring enhancement on the edge; emboli were found in the main and/or branches of portal vein (21/36 cases, 58.3%). (5) In the short-term review (minimum 5 days), the lesions became smaller or disappeared, and the local liver volume became smaller or the surface was depressed. Conclusions Hepatic ischemia/necrosis occurs after hepatosplenic surgery and upper gastrointestinal hemorrhage. The imaging manifestations are multiple nodular or flaky hypovascular foci, and the short-term review shows a markedly improvement. It needs to be differentiated from infection and metastasis of malignant tumors after operation.

Objective To investigate the effect of a Chinese medicine formula GAPT, a combination containing Chinese herbs ginseng,Acorus tatarinowii, Polygala and tuber curcuma, on the behavior and cholinergic system in mice with scopolamine-induced memory impairment, and to explore the neuroprotective mechanism of GAPT. Methods ICR mice were randomly divided into normal control group(solution of 0.5% carboxy methyl cellulose, CMC), model group (0.5% CMC),positive control group(donepezil, 0.92 mg/(kg·d)), GAPT high, medium and low dose groups(20 mg/(kg·d),10 mg/(kg·d),5 mg/(kg·d)),18 mice in each group, were given intragastric gavage once a day for 30 days. After the last administration,the control group and model group received intraperitoneal injection of normal saline,and the other groups intraperitoneal injection of scopolamine(3 mg/(kg·d)), dissolved in 0.9% normal saline. Morris water maze test was performed to assess the learning and memmory ability. Then the mice were killed and the Ach content and AchE and ChAT activity in the cortex and hippocampus were detected. Results GAPT increased the swimming dis-tance,swimming time and the residence time in target quadrant of the model mice,increased the content of Ach and the ac-tivity of ChAT,and decreased the activity of AchE in the brain of the model group. Conclusions GAPT can improve the learning and memory ability of mice induced by scopolamine,and its mechanism may be related to cholinergic system.

Objective To explore the implementation methods and effects of precise quality control model mediated by nursing quality indexes in quality management.Methods Fifty-seven care units with complete quality control data were collected. From January to December 2015, the 57 using the traditional quality control mode were selected as control group, whilst from January to December 201657 units were chosen for the intervention group using precision quality control mode, that was, to select the number of indicators and target values, screening quality control points, unified the acquisition path of indicators, lock the key departments and monitoring points affecting the quality to carry out quality management performance. We observed the changes of the two groups of quality indicators.Results The nine process quality indicators including wards 6S management, first aid techniques, health education, primary care, first class and critical care nursing, safe treatment, operating nursing documents,drug and sterile product quality and pass rate of identity verification were significant difference between the two groups(P<0.05). The five outcome quality indicators including hospitalized patients fall, dosing defects, hospital pressure sores, burns and urinary uncontrolled extubation rates were significant difference between the two groups(P<0.05) as well.Conclusions The quality control model, which is mediated by the nursing quality index, is helpful to improve the nursing quality. It is an effective quality control mode to achieve continuous improvement of nursing quality.

In order to develop potent antidiabetic agents that have inhibitory effect to a-glucosidase, twelve β-acetamido ketone derivatives such as N-{[(substituted-4-oxo-thiochroman-3-yl)phenyl]-methyl}acetamide are designed and synthesized through one-pot Dakin-West reaction. Their chemical structures are confirmed by 1H NMR, 13C NMR, IR and HR-MS. In vitro α-glucosidase inhibition assays of compounds 4a-41 were carried out using glucose oxidase method. The result indicated that most of them possess inhibitory activity in vitro. Compound 4k showed the most potent inhibitory activity with 87.3% inhibition of α-glucosidase at the concentration of 5.39 mmol x L(-1). The structure-activity relationship of these β-acetamido ketone derivatives was discussed preliminarily. Moreover, the molecular docking method was used to study the interaction mode of compound 4k and α-glucosidase. Our results will be helpful for designing of α-glucosidase inhibitors in the future.

Long-term therapy should be administrated for patients with schizophrenia and the medication adherence is very important for the prognosis and outcome in these patients. In this study, we screened the literatures from various databases in accordance with our search criteria. A total of 11 literatures with the results of reliability and validity regarding the measurement of schizophrenia medication adherence were enrolled in our analysis. Based on the measurements, they were classified into subjective methods and objective ones. The objective methods include blood plasma and urine concentrations, pharmacy records, pill counts and Medication Event Monitoring System. The subjective methods include Drug Attitude Inventory, Rating of Medication Influences Scale, Brief Evaluation of Medication Influences and Beliefs, the Brief Adherence Rating Scale, Medication Adherence Rating Scale, and Morisky scales. In general, single method for measuring medication adherence in patients with schizophrenia is limited. We recommend researchers to use 2 or more methods when measuring the medication adherence in patients with schizophrenia.

Objective To investigate feasibility and effectiveness of combined level-one quality control and management mode. Methods Contents of combined level-one quality control and management mode were introduced, including determining departments combination, establishment and work procedure of the combined quality control group, frequency of combined quality control, and approaches of continuous quality improvement. Quality control data of the Nursing Department from January 2013 to December 2014 were taken to statistically analyze compliance rate of 6 nursing quality standards, satisfaction of hospitalized patients, and incidence of nursing defects, before and after implement of combined quality control&management mode. Results Compared with before, after implementation of combined level-one quality control and management mode, compliance rates of nursing documentation, basic nursing, treatment safety, head nurse management, and ward management, as well as satisfaction of hospitalized patients, and incidence of nursing defects were statistically significant (χ2 =4. 182, 8. 177, 6. 157, 5. 148, 5. 135, 7. 875, 7. 754; P <0. 05). Compliance rates of health education quality before and after the implementation were not statisticallysignificant (χ2 = 4. 182, P > 0. 05 ). Conclusions Implementation of combined level-one quality control and management mode can improve compliance rate of nursing quality standards and satisfaction of hospitalized patients, and decrease incidence of nursing defects, which is a new feasible and effective management mode in clinical work.

Objective To investigate the role of rat organic anion transporter 1 (OAT1, SLC22A6) in the renal cellular uptake of AA Ⅰ and its impact on cellular toxicity. Methods HEK-293 cells were transfeeted with rat OAT1 cDNA or empty vectors. The over-expression of rOAT1 was confirmed by Western blot analysis and its activity was validated by using para-aminohippurate (PAH) as a probe. Cellular apoptosis was examined by flow cytometery using propodium iodode (PI) and annexin V-FITC staining. Results Concentration-and time-dependent intracellular accumulation of AA Ⅰ was observed in rOATl-transfected HEK-293 cells. After treatment with AA Ⅰ at the concentrations of 40 mg/L, 80 mg/L, 120 mg/L and 160 mg/L,respectively, for 45 min, the intracellular concentrations of AA Ⅰ in rOAT1-transfected HEK-293 cells were higher than those in controls (P<0.05). After treatment with AA Ⅰ (120 mg/L for 30 min, 60 min, 90 min and 120 min, respectively, the intracellular concentrations of AA Ⅰ in rOAT1-transfected HEK-293 cells were higher than those in controls (P<0.05). PAH significantly reduced the intracellular accumulations of AA Ⅰ in rOAT1-transfected HEK-293 cells. After treatment with AA Ⅰ at the concentrations of 40 mg/L, 80 mg/L, 120 mg/L and 160 mg/L respectively for 35 min, the intracellular accumulations of AA Ⅰ in rOAT1-transfected HEK-293 cells that treated with PAH were lower than those that were not treated by PAH. Cellular apoptosis and caspase-3 expression in rOAT1-transfeeted HEK-293 cells were significantly up-regnlated as compared to controls (P<0.05). Conclusion rOAT1 is involved in the cellular uptake of AA Ⅰ which leads to increased epithelial apoptosis. Further studies are suggested to investigate the role of human OAT in the disposition of AA and its toxicological consequences.
