Subacute cholecystitis complicated by gallbladder perforation often manifests as inflammatory lesions around the gallbladder， and it is extremely rare for this condition to cause massive hemorrhage into the omental bursa with secondary infection and result in massive hemorrhagic abscess. This article reports a case of a female patient， aged 68 years， who experienced massive hemorrhagic abscess in the omental bursa due to localized perforation and bleeding caused by a stone impacted in the gallbladder neck. The patient had a history of gallstones for 30 years and was admitted to Tianjin Nankai Hospital， Tianjin Medical University， after tertiary referral due to aggravated abdominal pain， chills， and fever. After comprehensive assessment by a multidisciplinary team， the patient underwent emergency laparoscopic cholecystectomy and clearance of the hemorrhagic abscess in the omental bursa. The patient recovered well and was discharged on day 10 after surgery， with good conditions during follow-up.

OBJECTIVE To evaluate the efficacy and safety of cholesterol absorption inhibitors （ezetimibe and hybutimibe） combined with statins for the treatment of dyslipidemia. METHODS Randomized controlled trials （RCTs） about above-mentioned drug combination in patients with dyslipidemia were retrieved from CNKI，PubMed and other Chinese and English databases. The retrieval time limit was from the establishment of the database to October 2025. After screening the literature，extracting the data，and evaluating the quality of the literature，network meta-analysis was performed using R software. RESULTS A total of 36 RCTs were included. Results showed that in reducing low-density lipoprotein cholesterol （LDL-C） and total cholesterol （TC）， ezetimibe+statins and hybutimibe+statins were significantly superior to statins+placebo and placebo alone （ P ＜0.05）. The top two interventions according to surface under the cumulative ranking curve （SUCRA） rankings were both ezetimibe+statins and hybutimibe+statins. In terms of triglyceride （TG） lowering， both hybutimibe+statins and ezetimibe+statins were significantly better than statins alone， statins+placebo and placebo alone （ P ＜0.05）， with hybutimibe+statins and ezetimibe+statins ranking top two by SUCRA. For apolipoprotein B （ApoB） reduction， ezetimibe+statins was significantly superior to statins alone and placebo alone （ P ＜0.05）， and the top two SUCRA rankings were ezetim ibe+statins and statins+placebo. In terms of high-density lipoprotein cholesterol （HDL-C） increase， placebo was significantly better than statins alone， hybutimibe+statins， statins+placebo， and ezetimibe+statins （ P ＜0.05）， and the top two SUCRA rankings were placebo alone and statins alone.There was no statistically significant difference in the overall incidence of adverse reactions among the interventions （ P ＞0.05）. CONCLUSIONS Ezetimibe combined with statins shows significant advantages in reducing LDL-C， TC and ApoB， while the hybutimibe combined with statins may have potential advantages in lowering TG； both combination regimens have good safety.

Objective:Using bacterial culture as the gold standard, to evaluate the agreement of rapid antigen detection test (RADT) and rapid nucleic acid test (RNAT) in diagnosing group A Streptococcus (GAS) pharyngitis in pediatric outpatients, and assess their potential clinical utility. Methods:This cross-sectional study prospectively collected throat swab specimens and clinical data of 338 children diagnosed with acute pharyngitis at the Department of Outpatient Beijing Children′s Hospital, Capital Medical University, between July 2023 and February 2024. The specimens were tested for GAS bacterial culture, RADT and RNAT. Using bacterial culture results as the reference standard, Kappa consistency analysis was performed to assess the diagnostic concordance between RADT and RNAT. Chi-square test was used to compare clinical characteristics between cases diagnosed by different methods.Results:In the 338 children diagnosed with pharyngitis, 195 were male and 143 were female, with an age at the visit of 7.4 (5.9, 7.4) years. The positivive rates for GAS detection were 25.7% (87/338) by bacterial culture, 20.7% (70/338) by RADT, and 41.7% (141/338) by RNAT. In terms of diagnostic performance, RADT exhibited a higher specificity (96.8% (243/251)) and better agreement with bacterial culture results ( κ=0.73), whereas RNAT showed greater sensitivity (95.4% (83/87)) but lower specificity (76.9% (193/251)) and moderate agreement ( κ=0.61). Among the 87 children with positive bacterial culture for GAS, 56 were male and 31 were female, with an age at visit of 7.3 (6.2, 8.8) years. Clinically, body temperature predominantly ranged from 38.1 to 39.0 ℃ in 48 cases (55.2%), and common accompanying symptoms included sore throat 62 cases (71.3%), cough 33 cases (37.9%), and cervical lymphadenopathy or tenderness 16 cases (18.4%). On physical examination, tonsillar enlargement was present in 73 cases (83.9%) and exudate in 37 cases (42.5%). The McIsaac score was most frequently 4 points, observed in 37 cases (42.5%). Laboratory tests showed a peripheral white blood cell (WBC) count of 14.5 (12.3, 18.7)×10?/L and C-reactive protein (CRP) concentration of 22.0 (10.1, 41.4) mg/L. There were no statistically significant differences in the proportion of fever, sore throat, cough, tender cervical lymphadenopathy, tonsillar exudates, or tonsillar enlargement, nor in WBC count or CRP, among children who tested positive by RADT, RNAT, or bacterial culture (all P>0.05). Conclusions:Compared with bacterial culture,the RADT demonstrates higher specificity, while the RNAT exhibits greater sensitivity. Both methods show good concordance with culture results and may serve as effective adjunctive tools for the early screening of GAS pharyngitis.

Objective:To investigate the clinicopathological characteristics, immunophenotypes, diagnostic criteria and differential diagnosis of atrophic kidney-like lesion (AKLL).Methods:Three cases of AKLL were collected from April 2021 to October 2023 at the Xiangya Hospital of Central South University, Changsha, Zhejiang Provincial People′s Hospital, Hangzhou and Ningbo Clinical Pathology Diagnosis Center, Ningbo, China. The clinical, morphological, and immunohistochemical characteristics were analyzed. Relevant literature was also reviewed. A targeted DNA-based next-generation sequencing (a panel of 150 genes) was performed on one of the three cases.Results:There were 1 female and 2 males, aged 30, 57, and 17 years (mean 34.6 years), respectively. The lesions were all incidentally identified during physical or imaging examination. Radiologically, they were all presented as a unilateral renal parenchymal mass. Grossly, the maximum diameters of the lesions were 1.8, 4.0, and 6.5 cm (mean 4.1 cm), respectively. The tumor cut-surfaces were sponge-like, multilocular cystic, and solid, respectively. At low magnification, the lesions were well-circumscribed, while a thick fibromuscular capsule was noted in cases 1 and 3. Cases 1 and 2 were composed of thin-walled cysts or follicular like structures of varying sizes, with the cyst wall lined by flattened and atrophic, or hobnail cells. The luminal spaces contained dense eosinophilic secretion and associated calcifications, while some cysts contained discohesive cells floating in the eosinophilic material. The tissue between the cysts showed predominantly small atrophic tubular structures. Case 3 was almost entirely composed of atrophic and collapsed tubular structures with focal cyst formation, imparting a solid sheets growth pattern under low magnification. Immunohistochemical staining revealed that the cyst lining cells and the intracystic floating cells were WT1 positive, PAX8 negative and CK7 negative, while the atrophic renal tubules were WT negative, PAX8 positive and CK7 positive. Targeted next-generation sequencing in case 1 showed no significant genetic abnormalities. All 3 patients underwent partial nephrectomy. No evidence of recurrence or metastasis was found with a follow-up of 17 to 36 months.Conclusions:AKLL is a rare and novel benign renal disease. It is easily misdiagnosed as a renal neoplasm grossly and histologically. Careful morphological observation combined with characteristic immunophenotypes can aid in its diagnosis and differential diagnosis.

Objective:To analyze the epidemiological and clinical characteristics of influenza A/B virus (IAV/IBV) infection in children aged 0-4 years in Jining city from 2022 to 2024.Methods:A retrospective analysis was conducted on the data of 3 106 influenza affected children who visited two monitoring outpost hospitals in Jining city from January 2022 to January 2024. They were separated into two groups based on the type of virus infection: IAV group (n=1 829) and IBV group (n=1 277). Two groups were compared for general information, epidemiological characteristics, and laboratory test indicators.Result:The majority of influenza patients were boys (59.01%) and 1-4 years old (63.01%), with peak body temperature mainly ranging from 37.8 to 38.9 ℃ (59.30%). Coughing (69.00%) and runny nose (66.03%) were the main manifestations. The onset season was concentrated in winter (42.43%) and spring (40.44%), and the exposure target were family members (51.90%), and the proportion of influenza vaccine injections (20.90%) was relatively low. The proportions of visit time≤3 d, peak body temperature≥39.0 ℃, myocardial damage, liver function damage, white blood cell count (WBC) of 4-10×10 9/L, and neutrophil percentage (N)>70% in the IAV group were higher than those in the IBV group ( P<0.05). The proportions of preschool children and WBC>10×10 9/L in the IBV group were higher than those in the IAV group ( P<0.05). Conclusions:Children aged 0-4 years who are infected with IAV in Jining City are more common in terms of high fever, early medical attention, impaired heart and liver function, normal WBC, and abnormal N elevation compared to those infected with IBV. However, children aged 0-4 who are infected with IBV have abnormally high WBC and are more common in daycare.

Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.

Objective To construct a key technical indicator system for in-hospital treatment and nursing of patients with nuclear radiation injury, and provide a basis for the implementation of such treatment and nursing. Methods The draft of the key technical indicator system for in-hospital treatment and nursing of patients with nuclear radiation injury was determined by literature review, case study, and field investigation. The indicators of the system were determined through two rounds of Delphi consultation and using the precedence chart method. According to the criteria of indicator evaluation, the reliability of expert opinions, and the opinions of the research group, the indicators were refined and evaluated. Results Twenty experts were included for two rounds of consultation via mailed inquiries, with a 100% effective response rate in both rounds. The expert authority coefficients were both 0.945, and the Kendall’s W values were 0.347 and 0.448, respectively (P < 0.05). Following the expert consultations, 1 indicator was deleted, 12 indicators were added, and 6 indicators were modified. The key technical indicator system for in-hospital treatment and nursing of patients with nuclear radiation injury established in this study included 4 first-level indicators, 17 second-level indicators, and 73 third-level indicators. The means of importance assignment for all indicators were > 4.00, and the coefficients of variation were < 0.25. Conclusion The key technical indicator system for in-hospital treatment and nursing of patients with nuclear radiation injury established in this study is scientifically rigorous and practically grounded. The indicators demonstrate strong professional relevance and provide important guidance for in-hospital treatment and nursing of patients with nuclear radiation injury.

BACKGROUND: Severe stroke has high rates of mortality and morbidity. This study aimed to investigate the clinical course, causes of worsening, and outcomes of severe ischemic stroke. METHODS: This prospective, multicenter cohort study enrolled adult patients admitted ≤30 days after ischemic stroke from nine hospitals in China between September 2017 and December 2019. Severe stroke was defined as a score of ≥15 on the National Institutes of Health Stroke Scale (NIHSS). Clinical worsening was defined as an increase of 4 in the NIHSS score from baseline. Unfavorable functional outcome was defined as a modified Rankin scale score ≥3 at 3 months and 1 year after stroke onset, respectively. We performed Logistic regression to explore baseline features and reperfusion therapies associated with clinical worsening and functional outcomes. RESULTS: Among 4201 patients enrolled, 854 patients (20.33%) had severe stroke on admission. Of 3347 patients without severe stroke on admission, 142 (4.24%) patients developed severe stroke in hospital. Of 854 patients with severe stroke on admission, 33.95% (290/854) experienced clinical worsening (median time from stroke onset: 43 h, Q1-Q3: 20-88 h), with brain edema (54.83% [159/290]) as the leading cause; 24.59% (210/854) of these patients died by 30 days, and 81.47% (677/831) and 78.44% (633/807) had unfavorable functional outcomes at 3 months and 1 year respectively. Reperfusion reduced the risk of worsening (adjusted odds ratio [OR]: 0.24, 95% confidence interval [CI]: 0.12-0.49, P  <0.01), 30-day death (adjusted OR: 0.22, 95% CI: 0.11-0.41, P  <0.01), and unfavorable functional outcomes at 3 months (adjusted OR: 0.24, 95% CI: 0.08-0.68, P <0.01) and 1 year (adjusted OR: 0.17, 95% CI: 0.06-0.50, P  <0.01). CONCLUSIONS: Approximately one-fifth of patients with ischemic stroke had severe neurological deficits on admission. Clinical worsening mainly occurred in the first 3 to 4 days after stroke onset, with brain edema as the leading cause of worsening. Reperfusion reduced the risk of clinical worsening and improved functional outcomes. REGISTRATION ClinicalTrials.gov , NCT03222024.
