Objective To explore the risk factors of progression to dementia within 2 years in patients with recent subcortical small infarction (RSSI) complicated with cognitive dysfunction. Methods A total of 340 patients with RSSI complicated with cognitive dysfunction who were treated in the hospital and completed 2-year follow-up were selected from February 2021 to February 2025. According to whether the patients progressed to dementia, they were classified into dementia group (n=105) and non-dementia group (n=235). The clinical data were compared between both groups, and the independent risk factors were screened by Logistic regression analysis. Results Multivariate logistic regression analysis suggested that history of hypertension (OR=1.919), history of diabetes mellitus (OR=1.597), multiple infarctions (OR=1.455), severe white matter lesions (OR=1.595), no cognitive function training (OR=1.923), increased infarct size (OR=1.069), reduced MMSE score (OR=0.945) and increased levels of NfL (OR=1.049) and IL-6 (OR=1.038) were independent risk factors for the progression to dementia (all P<0.05). Conclusion The progression to dementia in patients with recent subcortical small infarction and cognitive dysfunction is affected by multiple factors. In clinical practice, the integration of vascular risk factors, imaging features, cognitive assessment and serum biomarkers (NfL, IL-6) helps to construct an early risk prediction model and implement targeted interventions for high-risk groups.

Objective: To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom. Methods: From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted. Results: The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05). Conclusions Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

We present a case of emphysematous pyelonephritis (EPN) in a patient who developed fever and generalized pain one week prior to admission. Initial laboratory tests at a local hospital revealed leukocytosis (WBC 17.23×10 9/L), thrombocytopenia (PLT 97×10 9/L), elevated serum creatinine (502 μmol/L), and severe hyperglycemia (31.11 mmol/L). The patient was transferred to our institution following 1 day of symptomatic treatment due to newly developed hallucinations and convulsions. One day after admission, the patient presented with impaired consciousness, cutaneous ecchymosis, and gross hematuria. CT showed extensive gas accumulation within and around the left kidney, with minimal gas noted along the medial diaphragmatic crus. Laboratory findings showed progressive leukocytosis (WBC 22.93×10 9/L), critical thrombocytopenia (PLT 11×10 9/L), and markedly elevated C-reactive protein (309.06 mg/L). After being transferred to the ICU for treatment, the vital signs were stable but the patient remained somnolent. A surgical exploration by the urology department revealed severe infection and necrosis of the left kidney, and a left nephrectomy was performed. Postoperative renal function monitoring showed persistent elevation of serum creatinine (>400 μmol/L), which gradually improved to 200.6 μmol/L following targeted therapy, along with normalized WBC (5.42×10 9/L) and platelet counts (363×10 9/L). The patient achieved full recovery with normal follow-up CT and renal function tests. This case emphasizes the severity of emphysematous pyelonephritis and underscores the multidisciplinary collaboration. Early diagnosis, timely surgical intervention, and critical care support are key to improving prognosis.

Objective To develop and validate a scoring system to predict the possibility of laparoscopic cholecystectomy (LC) conversion to laparotomy based on preoperative clinical data, and to establish a grading management model of surgery. Methods A retrospective analysis was conducted on the clinical data of 9 414 patients who underwent LC at Renhe Hospital and Huashan Hospital from June 2013 to June 2018. The patients were divided into two groups: the LC group (9 246 patients who successfully underwent LC) and the conversion to laparotomy group (168 patients who required conversion to open surgery). The data of two groups were compared, and the risk factors affecting conversion to laparotomy were screened out by single factor analysis of Chi-square test. Then, the risk factors were analyzed by multiple Logistic regression, and the pre-coefficient of each variable of the risk factors was assigned according to the established conversion to laparotomy possibility function. After calculating the score of each case, the difference in the actual conversion rate of each group was compared. The area under receiver operating characteristic (ROC) curve was calculated to evaluate the performance of the scoring system. According to the scoring system, LC surgical grading management model was created and verified. Results The following factors were identified as significant risk factors for conversion to laparotomy (P < 0.001): body temperature ≥ 38.5℃, frequency of acute cholecystitis ≥3 times, maximum thickness of gallbladder wall ≥ 5 mm, gallbladder neck stone incarceration, diameter of common bile duct ≥8 mm, and surgical experience ≤50 cases were the risk factors for conversion to laparotomy (P < 0.001). A score >3 points was associated with a high risk of conversion to laparotomy. Conclusions The LC scoring system and surgical grading management are reliable and effective tools for predicting and reducing the conversion rate of LC to laparotomy.

Objective To analyze the factors affecting the prevalence of hyperuricemia(HUA)in an island troop.Methods A total of 1 113 soldiers stationed on an island from December 2021 to December 2022 were selected as research objects by cluster sampling.Their lifestyle and health information were collected.Physical examination and laboratory detection were conducted.Multivariate logistic regression was used to analyze the influencing factors of HUA.Results The prevalence rate of HUA was 21.02%(234/1 113).There were significant differences in the body mass index(BMI),waist-to-hip ratio,triglyceride,alanine aminotransferase,and creatinine between the soldiers with hyperuricemia and the soldiers with normal blood uric acid(P<0.05).Multivariate logistic regression analysis showed that BMI≥24(OR=1.49,95%CI:1.09-2.05),abnormal liver function(OR=2.26,95%CI:1.31-3.92),and dyslipidemia(OR=1.46,95%CI:1.01-2.12)were positively correlated with hyperuricemia;age>30 years old(OR=0.59,95%CI:0.37-0.93)and exercise time>1 h per week(OR=0.46,95%CI:0.22-0.97)were negatively correlated with HUA.Conclusion The prevalence rate of hyperuricemia is at a high level in an island troop.BMI≥24,age≤30 years old,exercise time≤1 h per week,abnormal liver function,and dyslipidemia are the risk factors for HUA.Prevention and control measures should be taken as early as possible for the soldiers with these risk factors.

Objective:To understand the status of bone health literacy in middle-aged and older female breast cancer patients undergoing chemotherapy and analyze its influencing factors using structural equation modeling.Methods:A convenience sampling method was used to select 250 middle-aged and older breast cancer patients undergoing chemotherapy in two tertiary hospitals in Xi'an from May to October 2024. Patients were surveyed using a general information questionnaire, the Bone Health Literacy Scale for Middle-Aged and Older Women, the Perceived Social Support Scale, and the General Self-Efficacy Scale. Pearson correlation analysis was used to examine the correlations among bone health literacy, perceived social support, and self-efficacy.Results:A total of 250 questionnaires were distributed, and 239 valid questionnaires were recovered, yielding an effective response rate of 95.6% (239/250). The mean score of the Bone Health Literacy Scale among the 239 patients was (39.71±8.16). Bone health literacy was positively correlated with perceived social support and self-efficacy ( P<0.01). Perceived social support directly affected bone health literacy and could also indirectly influence it through general self-efficacy, with an indirect effect value of 0.367, accounting for 45.2% of the total effect (0.367/0.812) . Conclusions:Healthcare professionals should implement effective interventions to enhance patients' perceived social support and strengthen their self-efficacy, thereby improving bone health literacy.

Objective:To analyze the etiological characteristics in patients pulmonary infection after esophageal cancer sur-gery and clinical significance of detecting peripheral blood activity of natural killer cell(NK),CD4+T cell subsets,and circulating tu-mor cell(CTC).Methods:A total of 108 patients with pulmonary infection undergoing radical resection of esophageal cancer in Chi-feng Songshan District Mongolian Medicine Hospital,from July 2020 to July 2022 were enrolled as infection group,while another 108 patients without pulmonary infection during the same period were enrolled as non-infection group.The levels of NK cells,CD4+T cell subsets and CTC in the peripheral blood of the two groups were detected 3 days after the operation.The disease severity was evaluated by clinical pulmonary infection score(CPIS).The correlation between CD4+T cell subsets,NK activity,CTC levels and CPIS were an-alyzed by Pearson and Spearman correlation analysis.The application value of each index for predicting pulmonary infection after esophageal cancer surgery was evaluated by receiver operating characteristic(ROC)curves.Multivariate Logistic regression analysis was used to analyze the risk factors of pulmonary infection after esophageal cancer surgery.Results:The levels of peripheral blood NK,CD4+T cells and CD4+T/CD8+T in infection group were significantly lower than those in non-infection group,while positive rate of serum CTC was significantly higher than that in non-infection group(P<0.05).The levels of peripheral blood NK,CD4+T cells and CD4+T/CD8+T in CTC positive group were significantly lower than those in CTC negative group(P<0.05).CPIS in patients with lung in-fection after esophageal cancer surgery was(4.18±1.29)points.Correlation analysis showed that levels of peripheral blood NK,CD4+T cells were significantly negatively correlated with CPIS,while CTC were significantly positively correlated with CPIS(P<0.05).AUC values of NK,CD4+T cell subsets and CTC for predicting lung infection were 0.694,0.757 and 0.574,respectively.The predictive value of NK and CD4+T cells subsets was better than that of CTC(P<0.05).Multivariate Logistic regression analysis showed that low levels of NK and CD4+T cell were independent risk factors of postoperative lung infection(P<0.05).Conclusion:Patients with pulmo-nary infection after esophageal cancer surgery have abnormal immune function,and low levels of NK cells and CD4+T cells are inde-pendent risk factors for postoperative pulmonary infection.Focusing on monitoring the levels of NK cells and CD4+T cells in the periph-eral blood of patients is helpful to grasp the development of the patient's condition and predict the occurrence of postoperative pulmo-nary infection.
