Objective: To explore the clinical features, treatment and prognosis of emphysematous pyelonephritis (EPN), so as to enhance the clinical awareness of this disease. Methods: A retrospective analysis was conducted on the clinical data of one EPN patient at The Second Affiliated Hospital, Guangzhou University of Chinese Medicine, and a literature review was performed on articles published in the China National Knowledge Infrastructure and PubMed databases from Jan.1, 2015 to Dec.31, 2024. Results: The patient, a 62-year-old male with a 5 years' history of type 2 diabetes, was admitted due to left flank pain for 4 days, with a temperature of 39.4 ℃.Laboratory tests indicated significantly elevated inflammatory markers, decreased platelet count, and abnormal coagulation function.Preoperative blood and urine cultures showed positivity for Escherichia coli.Computed tomography (CT) revealed complete erosion of the left kidney, with gas in the left ureter and surrounding effusion, as well as multiple free gas in the abdominal cavity, bilateral ureteral stones, right renal lower calyx stones.After a multidisciplinary consultation, he underwent emergency phase Ⅰ left pyeloplasty and perirenal drainage with ureteral stenting.After discharge, the patient received maintenance hemodialysis once every two days in the outpatient clinic.One week after-discharge, the patient was readmitted due to polypnea.Following symptomatic management, vital signs stabilized.Approximately 2 months after the first-stage surgery, ureteroscopic stone extraction was successfully performed.One month after the stone extraction procedure, a follow-up CT showed normalization of the left kidney, renal pelvis and calyces, leading to phase Ⅱ laparoscopic left nephrectomy via the abdominal approach, with postoperative pathology indicating renal necrosis.Among 89 EPN patients reported in 35 articles, the median age was 58(24-92) years old；there were 59（66.3%） females and 30（33.7%） males；fever was the most common clinical symptom (60.7%)；73(82.0%) had diabetes, 12 (13.5%) had urinary tract obstruction；55 (61.8%) were infected with Escherichia coli, and 7 (7.9%) were infected with Klebsiella pneumoniae; 13 died due to ineffective treatmen. Conclusion: EPN presents acutely and progresses rapidly, often leading to misdiagnosis due to the lack of specific early symptoms.Abdominal CT is the preferred imaging modality for rapid diagnosis, and proactive interdisciplinary intervention can improve survival rates, reduce the need for nephrectomy, and enhance prognosis.

OBJECTIVE To analyze the drug resistance,laboratory indicators and clinical characteristics of blood-stream infections caused by Enterobacter in children,providing references for early empirical treatment.METHODS A retrospective analysis was conducted on the clinical data of 302 children(aged 29 days to 12 years)with bloodstream infections caused by Enterobacter(monomicrobial infections)admitted to the Maternity and Child Health Care of Guangxi Zhuang Autonomous Region from Jan.2017 to Dec.2023.The drug resistance of Enterobacter and major pathogens were analyzed across different age groups of children.Based on prognosis,the children were divided into a favorable prognosis group(266 cases)and a poor prognosis group(36 cases),and their laboratory indicators and clinical characteristics were compared.Multivariate logistic regression was used to analyze the risk factors for poor prognosis.RESULTS The major pathogens causing infections were Salmonella,Escherichia coli and Klebsiella pneumoniae.The distribution difference of major pathogens across age groups(29 days-6 months,＞6 months-1 year,＞1-2 years,＞2 years)was statistically significant(P＜0.001).The drug resistance rates of Salmonella to ampicillin,chloramphenicol and sulfamethoxazole/trimethoprim were 68.61％,54.01％and 44.53％,respectively.E.coli exhibited drug resistance rates of 83.33％,52.22％and 47 78％to ampicillin,sulfamethoxazole/trimethoprim and cefazolin,respectively.K.pneumoniae showed drug resistance rates exceeding 50％to ampicillin/sulbactam,cefuroxime and cefazolin.Hypoalbuminemia(OR=3.319),sepsis(OR=3.122),ventricular purulent encephalitis(OR=5.104)and prior use of penicillin-class anti-bacterial drugs before culture positivity(OR=3.374)were identified as risk factors for poor prognosis of the chil-dren with Enterobacteriaceae bloodstream infections(P＜0.05).CONCLUSIONS Bloodstream infections caused by Enterobacter in children predominantly occur in those under 2 years of age,with Salmonella,E.coli and K.pneumoniae as the major pathogens,exhibiting high drug resistance rates to penicillin and cephalosporin antibacte-rial drugs.Clinical therapeutic regimen should be adjusted early based on laboratory indicators and risk factors to improve prognosis.

Objective:To explore the impact of plant and animal dietary behaviors on type 2 diabetes mellitus (T2DM) in older adults aged ≥65 in 18 longevity areas of China.Methods:The subjects were 5 223 older adults over 65 years old from the Healthy Ageing and Biomarkers Cohort Study (HABCS) in 18 longevity areas in China. Through a questionnaire survey and physical examination, information about their demographic characteristics, lifestyles, daily activities, self-health status, current diseases, and fasting venous blood were collected. Food Frequency and Questionnaire (FFQ) was used to collect data on food intake frequency. Based on the prior method, the plant-based diet index (PDI) and animal-based diet index (ADI) of 5 223 older adults were calculated. Subjects were divided into three groups (low-level group: PDI<39 or ADI<31, middle-level group: 39≤PDI≤42 or 31≤ADI≤34, high-level group: PDI>42 or ADI>34) by tertiles of PDI and ADI. Multivariate logistic regression was used to analyze the association between PDI and ADI and the risk of T2DM.Results:The average age of 5 223 subjects was (84.8±11.5) years, with the median ( Q1, Q3) of PDI about 41(38, 43) and the median ( Q1, Q3) of ADI about 33 (30, 35). The prevalence rate of T2DM was 16.41% (857/5 223). After adjusting for covariates, multivariate logistic regression showed that PDI was negatively associated with T2DM. Compared with the low-level group, the OR (95% CI) for T2DM in the high-level group was 0.83 (0.69-0.99). ADI was positively associated with T2DM, and compared with the low-level group, the OR (95% CI) for T2DM in the high-level group was 1.28 (1.06-1.55). For every one-point increase in PDI and ADI, the risk of T2DM decreased by 2% and increased by 3%, respectively, with the OR (95% CI) of 0.98 (0.96-1.00) and 1.03 (1.01-1.06), respectively. Conclusion:In Chinese older adults ≥65 years in 18 longevity areas, higher adherence to the plant-based behavior may be negatively associated with the risk of T2DM, while higher adherence to the animal-based behavior may be positively associated with the risk of T2DM.

Objective To assess the clinical value of a novel surgical technique—Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in the resection of anterior mediastinal masses. Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.

Objective To analyze the clinical characteristics,drug resistance and risk factors for poor prognosis in children patients with carbapenem resistant Klebsiella pneumoniae(CRKP)infection.Methods The samples of CRKP isolated from the children inpatients in this hospital from August 5,2016 to December 31,2020 were collected.The clinical data and drug resistance of CRKP in the patients with CRKP positive were analyzed.The risk factors in the poor prognosis group and good prognosis group of children pa-tients with CRKP infection conducted the correlation analysis.Results A total of 106 strains of non-repeti-tive CRKP were collected,which were mainly isolated from the patients ≤ 1 year old.The department distri-bution was dominated by the neonatal ICU and comprehensive ICU.CRKP showed the high resistance to mul-tiple antibacterial drugs,and its resistance rates to amikacin,levofloxacin,gentamicin,ciprofloxacin,minocy-cline and chloramphenicol were less than 30％.The poor prognosis rate in the children patients with CRKP in-fection reached 27.4％.The logistic multivariate regression analysis results showed that the multiple organ dysfunction and anemia were the independent risk factors for poor prognosis in the children patients with CRKP infection(P＜0.05).Conclusion The children CRKP infection is mainly the infants ≤1 years old,and CRKP shows the high resistance to multiple antibacterial drugs,the independent risk factors of poor prognosis include the multiple organ dysfunction and anemia

Objective:To explore the impact of sleep duration, physical exercise, and their interactions on the risk of dyslipidemia in older adults aged ≥80 (the oldest old) in China.Methods:The study subjects were the oldest old from four rounds of Healthy Aging and Biomarkers Cohort Study (2008-2009, 2011-2012, 2014 and 2017-2018). The information about their demographic characteristics, lifestyles, physical examination results and others were collected, and fasting venous blood samples were collected from them for blood lipid testing. Competing risk model was used to analyze the causal associations of sleep duration and physical exercise with the risk for dyslipidemia. Restricted cubic spline (RCS) function was used to explore the dose-response relationship between sleep duration and the risk for dyslipidemia. Additive and multiplicative interaction model were used to explore the interaction of sleep duration and physical exercise on the risk for dyslipidemia.Results:The average age of 1 809 subjects was (93.1±7.7) years, 65.1% of them were women. The average sleep duration of the subjects was (8.0±2.5) hours/day, 28.1% of them had sleep duration for less than 7 hours/day, and 27.2% had sleep for duration more than 9 hours/day at baseline survey. During the 9-year cumulative follow-up of 6 150.6 person years (follow-up of average 3.4 years for one person), there were 304 new cases of dyslipidemia, with an incidence density of 4 942.6/100 000 person years. The results of competitive risk model analysis showed that compared with those who slept for 7-9 hours/day, the risk for dyslipidemia in oldest old with sleep duration >9 hours/day increased by 22% ( HR=1.22, 95% CI: 1.07-1.39). Compared with the oldest old having no physical exercise, the risk for dyslipidemia in the oldest old having physical exercise decreased by 33% ( HR=0.67, 95% CI: 0.57-0.78). The RCS function showed a linear positive dose-response relationship between sleep duration and the risk for hyperlipidemia. The interaction analysis showed that physical exercise and sleep duration had an antagonistic effect on the risk for hyperlipidemia. Conclusion:Physical exercise could reduce the adverse effects of prolonged sleep on blood lipids in the oldest old.
