Objective To construct a prediction model for the population with hypertension and diabetes to assess the risk of chronic kidney disease (CKD), and to provide a scientific basis for formulating targeted CKD prevention and control measures. Methods Based on physical examination data from community residents aged 60 years and above in Nanjing in 2022, 10 221 patients with hypertension and diabetes were selected as the study subjects. Variables associated with CKD prevalence were screened using univariate analysis, and further variable selection was performed using LASSO regression. Finally, a CKD risk prediction model was constructed based on logistic regression. The model's performance was evaluated using the ROC curve and calibration curve. Results The prevalence rate of CKD in the study population was 22.71%, with a mean age of 71.66 years. LASSO regression identified seven variables associated with CKD: age, blood urea nitrogen (BUN), hemoglobin, uric acid, triglyceride-glucose (TyG) index, urine protein-to-creatinine ratio (UPCR), and medical insurance type. The final logistic regression model incorporated six variables: age [OR=1.067 (95% CI: 1.058-1.076)], BUN [OR=1.377 (95% CI: 1.338-1.418)], hemoglobin [OR=0.992 (95% CI: 0.989-0.995)], uric acid [OR=1.004 (95% CI: 1.003-1.004)], TyG index [OR=1.445 (95% CI: 1.324-1.577)], and self-payment medical insurance [OR=1.732 (95% CI: 1.542-1.945)]. The model had an AUC of 0.759 (95% CI: 0.747-0.770) and a Brier score of 0.140 (95% CI: 0.136-0.145), indicating good predictive performance. The calibration curve showed good agreement between the predicted risk and the observed value. Conclusion The constructed LASSO-logistic regression risk prediction model in this study can effectively assess the risk of CKD in elderly individuals aged 60 years and above with hypertension and diabetes, providing a basis for early identification of high-risk individuals and the formulation of targeted CKD prevention and control measures.

Objective To explore the impact of irregular shape of head CT hematomas on postoperative re-bleeding and prognosis of patients with spontaneous intracerebral hemorrhage(ICH)who undergo craniotomy for hematoma evacuation.Methods We retrospectively enrolled consecutive patients with ICH who underwent craniotomy for hematoma evacuation in the Department of Neurosurgery of the Second People's Hospital of Guiyang Affiliated to Guizhou Medical University from January 2019 to June 2024.Baseline and clinical data were collected form the patients,including age,gender,smoking history,drinking history,hypertension,diabetes,history of anticoagulant use,admission systolic and diastolic blood pressure,admission National Institutes of Health stroke scale(NIHSS)score,Glasgow coma scale(GCS)score,time from onset to the first head CT,neutrophil-to-lymphocyte ratio(NLR),and platelet-to-lymphocyte ratio(PLR).Admission head CT scans were used to assess hematoma shape(regular or irregular),hematoma location(basal ganglia,lobar,multifocal),hematoma volume,perihematomal edema volume,the presence of midline shift,and intraventricular extension.Volume of the hematoma was assessed 2 days after surgery.Postoperative re-bleeding is defined as an increase in the volume of the hematoma by 12.5 ml compared to the previous postoperative CT scan within 2 weeks after surgery,or the reappearance of high-density areas in the focal area of the head CT scan during follow-up after complete hematoma clearance.Conduct patients follow-ups via telephone at 6 months postoperatively to assess their modified Rankin scale(mRS)scores.The sliding dichotomy method was applied to define prognosis based on the patients' baseline characteristics and disease severity.The prognostic score was calculated using formula:10 × admission GCS score-age-0.64 × admission hematoma volume.A prognostic score>27.672 was considered potentially favorable,while a score ≤ 27.672 was considered potentially unfavorable.For patients with a potentially favorable prognosis,an mRS score of 0-2 was defined as a good outcome,and a score of 3-6 as a poor outcome.For those with a potentially unfavorable prognosis,an mRS score of 0-3 was defined as a good outcome,and a score of 4-6 as a poor outcome.In the comparison of baseline and clinical data between patients with regular and irregular hematoma shapes,factors with P<0.05 were included in propensity score matching(PSM)to adjust for confounding variables.A 1∶1 matching was performed using the nearest neighbor method with a caliper value set to 0.25.Variables with statistically significant differences between groups after PSM matching were included in the multivariate Logistic regression analysis to identify influencing factors for postoperative re-bleeding and poor prognosis in ICH patients undergoing craniotomy hematoma evacuation.The predictive value of irregular hematoma shape for postoperative rebleeding and poor prognosis in ICH patients was analyzed using receiver operating characteristic(ROC)curve analysis.Results(1)A total of 440 ICH patients were enrolled,including 342 males and 98 females,aged from 20 to 84 years with a mean age of(56±12)years.Statistically significant differences were observed in baseline and clinical data between patients with regular and irregular hematoma shapes before PSM,including age,admission GCS score,NIHSS score,NLR,proportion of patients with hematoma rupture into ventricles,preoperative hematoma volume,proportion of patients with midline shift,preoperative volume of hematoma surrounding edema,proportion of patients with hematoma located in multiple sites,and postoperative 2-day hematoma volume(all P<0.05).After propensity score matching of these factors,298 ICH patients were included in the statistical analysis,comprising 228 males and 70 females,with an age range of 20 to 84 years and a mean age of(57±12)years.Following PSM,no statistically significant differences were observed in the baseline and clinical characteristics between patients with irregular and regular hematoma shapes(all P>0.05).(2)After propensity score matching,28 patients experienced postoperative re-bleeding while 270 did not.Significant differences were observed between the two groups in the following factors:proportion of patients with a history of anticoagulant use,admission PLR,NLR,irregular hematoma shape,and hematoma volume at 2 days after operation(all P<0.05).No statistically significant differences were found in the remaining baseline and clinical characteristics(all P>0.05).Using postoperative re-bleeding as the dependent variable and incorporating factors with P<0.05 from the univariate analysis as independent variables,multivariate Logistic regression analysis identified irregular hematoma shape(OR,2.821,95%CI 1.142-6.968,P=0.025)and larger hematoma volume at 2 days post-operation(OR,1.062,95%CI 1.026-1.099,P<0.01)as independent risk factors for re-bleeding following intracranial hematoma evacuation in ICH patients.ROC curve analysis demonstrated that irregular hematoma shape predicted postoperative re-bleeding with an area under the curve(AUC)of 0.62,showing a sensitivity of 71.4%and a specificity of 52.2%.(3)After propensity score matching,174 patients had poor prognosis while 124 had good prognosis.Significant intergroup differences were observed in age,admission GCS score,NIHSS score,irregular hematoma shape,proportion of patients with hematomas located in the basal ganglia and cerebral lobes,and hematoma volume at 2 days post-operation(all P<0.05).No statistically significant differences were found in the remaining baseline and clinical characteristics(all P>0.05).Using poor prognosis as the dependent variable and incorporating factors with P<0.05 from univariate analysis as independent variables,multivariate Logistic regression analysis revealed that advanced age(OR,1.039,95%CI 1.015-1.064,P=0.002),high admission NIHSS score(OR,1.068,95%CI 1.025-1.113,P=0.002),irregular hematoma shape(OR,2.675,95%CI 1.582-4.524,P<0.01),and larger hematoma volume at 2 days post-operation(OR,1.033,95%CI 1.002-1.064,P=0.038)were independent risk factors for poor prognosis.Conversely,lobar hematoma location(OR,0.192,95%CI 0.073-0.504,P<0.01)was identified as a protective factor.ROC curve analysis showed that irregular hematoma shape predicted poor prognosis after intracranial hematoma evacuation with an AUC of 0.61,demonstrating a sensitivity of 59.2%and specificity of 62.9%.Conclusion Irregular hematoma shape on head CT is an independent risk factor for both postoperative re-bleeding and poor prognosis in ICH patients undergoing craniotomy for hematoma evacuation.

Objective To study the correlation between apolipoprotein AⅣ (APOA4) and leucine-rich α-2 glycoprotein 1 (LRG1) expression and clinicopathological features in breast cancer tissues. Methods Clinical data of 120 patients diagnosed with breast cancer after surgical treatment and postoperative pathology were collected from the Third People's Hospital of Zigong City from March 2020 to September 2022. Western blotting (WB) was used to observe the expression of APOA4 and LRG1 in breast cancer tissues and corresponding paracuncinoma tissues (>5cm from the margin of cancer tissues). Analyzed the relationship between the expression of APOA4 and LRG1 and the clinicopathological features of breast cancer. The correlation between the expression of APOA4 and LRG1 was analyzed by Pearson methed. Kaplan-Meier survival analysis of the relationship between APOA4 and LRG1 protein expression and prognosis. Results The results of WB detection showed that the expression levels of APOA4 (2.81±0.74)and LRG1(1.01±0.26)in breast cancer tissues were significantly higher than those in normal breast tissues (1.26±0.38,0.57±0.12),and the differences were statistically significant (t=20.411,16.832,all P<0.05). Pearson correlation analysis showed that APOA4 was positively correlated with LRG1 protein expression in breast cancer tissues (r=0.624,P=0.014). The expression levels of APOA4 and LRG1 proteins in breast cancer tissues with ER positive,PR positive and lymph node metastasis in cTNM stage Ⅱ to Ⅲ were higher than those in breast cancer tissues with ER negative,PR negative and no lymph node metastasis in cTNM stage Ⅰ,and the differences were statistically significant (t=1.770~3.284,all P<0.05). The expression of APOA4 protein in breast cancer tissues with BMI ≥ 23.5kg/m2 was higher than that in breast cancer tissues with BMI<23.5kg/m2,and the difference was statistically significant (t=1.736,P=0.043). Kaplan-Meier survival analysis showed that the cumulative overall survival rates (83.13%,84.93%) of the APOA4 high expression group and LRG1 high expression group were lower than those of the APOA4 low expression group and LRG1 low expression group (94.74%,91.49%,and the differences were statistically significant (Log Rankx2==4.778,3.956,P=0.029,0.047). Conclusion Both APOA4 and LRG1 proteins are highly expressed in breast cancer tissues,and are involved in the occurrence and invasion of breast cancer. They are expected to become a reference index for diagnosis and treatment and prognosis prediction.

Objective:To investigate the regulatory role and mechanism of synaptic vesicle protein 2A (SV2A) in apoptosis of drug-resistant epilepsy neurons.Methods:One hundred and fifty specific pathogen-free (SPF) Sprague-Dawley (SD) rats were randomly numbered; 20 rats were selected as a normal control group (NC group), and the remaining 130 rats were subjected to chronic epilepsy models of lithium-pilocarpine. Phenobarbital and phenytoin sodium for 2 weeks were given to these rats after modeling; fanally, 94 rats with chronic epilepsy were divided into a drug-resistant group (phenobarbital and phenytoin sodium-resistant epilepsy [PRE] group, reduction in episodes<50%, n= 55) and a drug-sensitive group (phenobarbital and phenytoin sodium-sensitive epilepsy [PSE] group, reduction in episodes by≥50%, n=38). Rats in the PRE group were further randomly divided into 5 groups, namely a up-regulated-SV2A PRE group (UPRE group), a down-regulated-SV2A PRE group (DPRE group), a up-regulated-SV2A control group (UPRC group), a down-regulated-SV2A control group (DPRC group), and a non-transfected PRE group; different types of lentivirus were given to the first 4 groups via stereotactic brain injection. Ten days after lentiviral transfection, virus detection was performed; and 2 weeks after lentiviral transfection, occurrence of epileptic seizures was observed, and after that, rats were sacrificed and the hippocampal tissues were collected for subsequent experiments. Western blotting was used to detect the expressions of SV2A, cyclophilin A (CyPA), apoptosis-inducing factor (AIF), and superoxide dismutase 2 (SOD2) in the cell nucleus or mitochondria; coimmunoprecipitation experiment was performed to observe the interaction among SV2A, CyPA and AIF proteins; immunofluorescent co-staining was used to observe the CyPA/AIF localization; mitochondrial damage was detected by electron microscopy; ATP content in the hippocampal tissues was detected by luciferase method, 8-hydroxy-2-deoxyguanosine (8-OHDG) expression was detected by immunofluorescent staining, and neuronal apoptosis rate was calculated by double staining with neuron-specific nuclear protein (NeuN) and TUNEL. Results:(1) Confocal microscopy revealed that the hippocampal tissues in the 4 transfected groups showed green fluorescence inherent to the lentivirus, indicating successful viral infection. Compared with the UPRC group, the UPRE group had significantly reduced frequency of epileptic seizures and seizure duration ( P<0.05). (2) Western blotting showed that, in mitochondria, the UPRE group had significantly higher expressions of SV2A (0.475± 0.105 vs. 0.136±0.043), CyPA (0.473±0.041 vs. 0.175±0.047), AIF (0.443±0.058 vs. 0.131±0.037), and SOD2 (0.457±0.037 vs. 0.152±0.038) compared with the UPRC group ( P<0.05); the DPRE group had significantly decreased expressions of SV2A (0.038±0.013 vs. 0.184±0.047), CyPA (0.041±0.010 vs. 0.214±0.040), AIF (0.040±0.019 vs. 0.175±0.046), and SOD2 (0.043±0.017 vs. 0.187±0.039) compared with the DPRC group ( P<0.05). In the cell nucleus, the UPRE group had significantly lower expressions of AIF (0.336±0.084 vs. 0.649±0.209) and CyPA (0.331±0.086 vs. 0.620±0.162) compared with the UPRC group ( P<0.05); the DPRE group had statistically higher expressions of AIF (0.771± 0.180 vs. 0.519±0.144) and CyPA (0.738±0.223 vs. 0.488±0.091) compared with the DPRC group ( P< 0.05). (3) Co-immunoprecipitation experiment results showed that the bidirectional precipitation results of SV2A and AIF, SV2A and CyPA, and AIF and CyPA were all positive, suggesting existence of interactions. (4) Immunofluorescent co-staining showed that the fluorescence changes of CyPA and AIF were consistent. (5) Electron microscopy showed that mitochondria in the NC group had intact structure; mitochondria in the UPRE group, UPRC group, DPRC group and DPRE group showed swelling and cristae fragmentation; among them, injury in the UPRE group was relatively less severe than that in the UPRC group, while that in the DPRC group was more severe than that in the DPRE group. (6) Compared with the UPRC group, the UPRE group had statistically higher ATP content ( P<0.05); compared with the DPRC group, the DPRE group had significantly lower ATP content ( P<0.05).(7) Immunofluorescent staining results showed that the UPRE group had significantly lower 8-OHDG expression than the UPRC group ( P<0.05); compared with the DPRC group, the DPRE group had statistically higher 8-OHDG expression ( P<0.05). (8) The UPRE group had significantly lower NeuN-TUNEL double staining positive rate than the UPRC group ( P<0.05); compared with the DPRC group, the DPRE group had significantly higher NeuN-TUNEL double staining positive rate ( P<0.05). Conclusion:SV2A can play a role in the apoptosis of hippocampal neurons in rats with drug-resistant epilepsy by regulating the nuclear translocation of AIF/CyPA and mitochondrial damage.
