OBJECTIVE To analyze the clinical characteristics and influential factors of drug-induced liver injury （DILI） in children caused by intravenous azithromycin. METHODS Clinical data of 157 DILI pediatric cases caused by intravenous azithromycin， reported by the Hengshui Adverse Drug Reaction Monitoring Center from January 2015 to January 2025， were collected as the observation group. Clinical data of pediatric patients who received intravenous azithromycin but did not develop DILI during the same period at Hengshui People’s Hospital were collected in a 1∶1 ratio to serve as the control group. The clinical classification， severity and prognosis of DILI in pediatric patients from the observation group were analyzed. Univariate and multivariate Logistic regression analyses were used to screen the independent risk factors for DILI in children caused by intravenous azithromycin. RESULTS Among 157 DILI cases， 92 cases （58.60%） had hepatocellular injury-type， 51 cases （32.48%） had cholestatic-type， and 14 cases （8.92%） had mixed-type. DILI severity was grade 1 in 117 cases （74.52%）， grade 2 in 33 cases （21.02%）， and grade 3 in 7 cases （4.46%）. Liver function had all recovered after stopping medication and symptomatic treatment. Combined with acetaminophen [OR＝3.769， 95%CI （1.615， 8.235）， P＝0.021]， daily dose of azithromycin＞10 mg/kg [OR＝ 2.237， 95%CI （1.075， 4.655）， P＝0.034] were independent risk factors for DILI in children caused by intravenous azithromycin. CONCLUSIONS Hepatocellular injury-type and cholestatic-type are relatively common in children with DILI caused by intravenous azithromycin， with mild severity being predominant and showing a favorable prognosis. Combination with acetaminophen and daily dose＞10 mg/kg are independent risk factors for azithromycin-induced DILI in children.

Objective:To reveal the current status and existing problems in the coupling and coordinated development of medical security and common prosperity in China,and to provide decision-making references for advancing the high-quality development of medical security,achieving the goal of common prosperity,and promoting the coordinated development of both systems.Methods:The entropy weight method was employed to measure the levels of medical security and common prosperity across 31 provinces from 2013 to 2022.A coupling coordination degree model was utilized to explore the coupling dynamic relationship between these two systems.Kernel density estimation was applied to analyze the dynamic evolution of their coupling coordination,while Moran's I and Dagum's Gini coefficient were used to investigate the spatial differentiation characteristics of their coupling coordination.Results:Over the decade,both medical security and common prosperity levels in different pronvinces improved significantly,with regional disparities continuously narrowing.The coordinated development degree between medical security and common prosperity achieved a substantial leap,shifting from provinces predominantly categorized as"barely coordinated"and"primary coordination"to those concentrated in"intermediate coordination".The coordinated development of medical security and common prosperity exhibits spatial spillover effects and spatial disparities,with the primary source of spatial differences stemming from disparities between the eastern region and other areas.Conclusion:Future efforts should focus on integrating the medical security system to enhance operational efficiency and reduce costs,promoting the scientific and rational allocation of medical resources guided by common prosperity,and driving high-quality coupling and coordinated development through dual-way empowerment between medical security and common prosperity.

OBJECTIVE To evaluate the efficacy and safety of rituximab （RTX） in the treatment of primary Sjögren syndrome （pSS）. METHODS Randomized controlled trials （RCTs） on the effects of RTX （trial group） versus placebo （control group） in the treatment of pSS were searched from the Cochran Library， PubMed， Embase， Medline， Web of Science， VIP， CNKI， Wanfang， and other databases during the inception to February 2024. After literature screening and quality evaluation， meta-analysis was performed by using RevMan 5.3 software. RESULTS Seven RCTs were finally included， involving a total of 518 patients. Results of meta-analysis showed that European League Against Rheumatism Sjögren syndrome disease activity index （ESSDAI） score [MD＝－1.17， 95%CI（－1.52， －0.82）， P＜0.000 01] and oral dryness visual analogue scale （VAS） score [MD＝－3.97， 95%CI （－5.08， －2.86）， P＜0.000 01] in the trial group were significantly lower than the control group； unstimulated salivary flow rate [SMD＝0.64， 95%CI（0.41， 0.87）， P＜0.000 01] and Schirmer score [MD＝0.19， 95%CI（0.18， 0.20）， P＜0.000 01] were significantly higher than the control group. There was no statistical significance in response rate [RD＝0.10， 95%CI（－0.04， 0.23）， P＝0.16]， fatigue VAS score [MD＝－12.50， 95%CI（－35.14， 10.15）， P＝0.28]， European League Against Rheumatism Sjögren syndrome patient reported index （ESSPRI） score [MD＝0.33， 95%CI（－0.53， 1.18）， P＝0.46]， Short-form 36 health survey physical component summary （SF36-PCS） score [MD＝0.90， 95%CI（－2.97， 4.78）， P＝0.65]， SF-36 mental component summary （SF36-MCS） score [MD＝0.11， 95%CI（－0.41， 0.63）， P＝0.68]， total salivary gland ultrasound score [SMD＝－1.91， 95%CI（－4.01， 0.19）， P＝0.07] or the incidence of adverse drug reactions [OR＝1.15，95%CI（0.62，2.13），P＝0.66] between 2 groups. CONCLUSIONS RTX has advantages in the improvement of ESSDAI score， unstimulated salivary flow rate， Schirmer score and oral dryness VAS score in pSS patients， and has a good safety profile. However， it did not exhibit significant improvement in fatigue VAS score， ESSPRI score， SF36-PCS score， SF36-MCS score or response rates.

Objective:To explore the clinical efficacy and safety of unilateral biportal endoscopic (UBE) and percutaneous transforaminal endoscopic discectomy (PTED) techniques in treating recurrent lumbar disc herniation (RLDH).Methods:This study is a retrospective cohort study. The clinical data were retrospectively collected from 68 patients who underwent surgical treatment for RLDH at Department of Mini-invasive Spinal Surgery, the Third People′s Hospital of Henan Province from June 2020 to June 2023. The patients were divided into the UBE group (38 cases) and the PTED group (30 cases) based on the surgical technique used. The drainage volume, surgery duration, and postoperative complications for revision surgeries in both groups were recorded. Visual analogue scale(VAS) and Oswestry disability index (ODI) were used to assess back pain and leg pain degrees and improvements preoperatively, 3 days postoperatively, 3 months postoperatively, and at the final follow-up. The modified Macnab criteria were used to evaluate outcomes at the final follow-up. The data comparison was conducted using independent sample t-test, repeated measures analysis of variance, χ2 test or Fisher's exact test. Results:All surgeries were successfully completed. The surgery duration in the UBE group was significantly shorter than in the PTED group, with statistically significant differences ((50.9±10.5)minutes vs.(55.9±12.5)minutes, t=1.234, P=0.001). All patients were followed up for more than 1 year, with a follow-up period of (18.1±5.6) months (range: 12 to 29 months). Both groups showed a significant reduction in VAS and ODI for back and leg pain at all postoperative time points compared to preoperative scores (all P<0.05). However, there were no statistically significant differences in VAS of low back pain, lower limb pain score and ODI score over time between the groups (all P>0.05). At the final follow-up, the UBE group had an excellent and good rate of 92.1% (35/38); the PTED group had an excellent and good rate of 86.6% (26/30)( χ2=0.727, P=0.867). One patient in the UBE group and three in the PTED group experienced cerebrospinal fluid leaks, and one patient in the PTED group experienced postoperative leg numbness; all were discharged after conservative treatment. At the final follow-up, lumbar X-rays, CT, and MRI evaluations showed no recurrence or instability at the surgical segments. Conclusions:Both UBE and PTED can achieve good clinical outcomes in the treatment of RLDH through continuous visualization. The choice of surgical method for RLDH should be more precisely tailored to the individual.

OBJECTIVE To analyze the influential factors for clinical efficacy of polymyxin B combined with other antibiotics in the treatment of carbapenem-resistant Acinetobacter baumannii(CRAB)pulmonary infection.METHODS A retrospective analysis was conducted on the clinical data of patients with CRAB pulmonary infection in our hospital from May 2021 to October 2024.Information such as age,gender,admitting department,infection status,underlying medical conditions,mechanical ventilation time,combination anti-infective treatment regimens,and the Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE-Ⅱ)score 24 h before medication was compiled.Based on the effectiveness of the treatment,patients were divided into treatment-effective group and treatment-ineffective group.Univariate analysis and multivariate Logistic regression analysis were employed to identify independent factors influencing clinical efficacy.RESULTS A total of 156 patients were included,and 108 patients were treated effectively,with an effective rate of 69.23%.The results of univariate analysis indicated that there were statistically significant differences between 2 groups in terms of the duration of mechanical ventilation time,APACHE-Ⅱ score 24 h before medication,the number of complication types,the proportion of abnormal coagulation function,anti-infective treatment course,and hospital stay before medication(P＜0.05).The results of multivariate Logistic regression analysis showed that APACHE-Ⅱ score≥15 points 24 h before medication[OR=2.965,95%CI(1.284,6.845),P=0.020],mechanical ventilation time≥10 d[OR=3.577,95%CI(1.185,10.793),P=0.037]and hospital stay≥14 d before medication[OR=2.422,95%CI(1.036,5.654),P=0.041]were independent risk factors,and anti-infective treatment course＞7 d was a protective factor[OR=0.445,95%CI(0.221,0.895),P=0.043].CONCLUSIONS This study shows that the effective rate of polymyxin B combined with other antibiotics in the treatment of CRAB pulmonary infection is less than 70%.The mechanical ventilation time≥10 d,APACHE-Ⅱ score≥15 points 24 h before medication,and hospital stay≥14 d before medication may lead to treatment failure,whereas anti-infective treatment course＞7 d may be associated with treatment success.

Objective:To investigate the endoscopic and pathological characteristics of metachronous early gastric cancer (EGC) after endoscopic submucosal dissection (ESD) for EGC.Methods:Data of 451 consecutive EGC patients treated with ESD at the Department of Gastroenterology, Peking University Third Hospital between 1 January, 2005 and 31 December, 2022 were retrospectively collected, of which 252 patients who met the criteria and had endoscopic follow-up ≥ 1 year were enrolled in the retrospective dynamic cohort. Multivariate Cox regression analysis was used to identify independent risk factors for metachronous EGC after ESD. Pearson's contingency coefficient was applied to analyze endoscopic correlation between the index and metachronous lesions. T-test, χ2 test, and Fisher exact test were used to compare endoscopic pathological features between index and metachronous lesions, the proportion of lesions meeting absolute ESD indication and their maximum diameters between patients undergoing annual vs bi-annual follow-up. Kaplan-Meier analysis assessed the cumulative incidence of metachronous EGC. Results:During a median follow-up of 40 months, 26 patients [10.3% (26/252)] developed metachronous EGC, with a mean interval of 43.9 months. Multivariate Cox regression identified the independent risk factors of index lesions including location in the middle third of the stomach ( HR=3.783, 95% CI: 1.300-11.011, P=0.015), in the anterior wall ( HR=3.934, 95% CI: 1.113-13.904, P=0.033), and the maximum diameter <15 mm ( HR=3.034, 95% CI: 1.074-8.571, P=0.036). Pearson's contingency coefficient showed no significant concordance between index and metachronous lesions for vertical location (C=0.375, P=0.372), horizontal location (C=0.508, P=0.434), gross morphology (C=0.287, P=0.675), or ulcer presence (C=0.194, P=0.313). Compared to index lesions, metachronous lesions were more frequently located on the posterior wall (lesser curvature/greater curvature/anterior wall/posterior wall: 11/2/1/12 VS 96/49/46/61, P=0.031), more often differentiated (differentiated/undifferentiated: 26/0 VS 214/38, P=0.032), and smaller in maximum diameter (8.08±5.99 mm VS 13.95±10.26 mm, t=4.383, P<0.001). No significant differences were observed between patients undergoing annual vs bi-annual follow-up in the proportion of metachronous lesions meeting absolute ESD indication (14/16 VS 9/9, P=0.520) or in maximum diameter (8.11±6.94 mm VS 6.67±4.35 mm, t=-0.275, P=0.535). The cumulative incidence curve of metachronous EGC plateaued after 10 years. Conclusion:Patients with EGC located in the middle third of the stomach, in the anterior wall, or of smaller diameter need intensive endoscopic surveillance after ESD. Posterior wall deserves particular attention during follow-up, with annual endoscopy recommended for at least 10 years post-ESD.

OBJECTIVE To systematically evaluate the influential factors for the clinical efficacy of tigecycline in the treatment of severe infections caused by multidrug-resistant Gram-negative bacteria （MDR-GNB）. METHODS Retrieved from PubMed， Embase， The Cochrane Library， CNKI database， Wanfang database and VIP database， the studies about the influential factors for the clinical efficacy of tigecycline in the treatment of adult patients with severe infections caused by MDR-GNB from the database construction to April 30， 2025. After screening literature， extracting data and evaluating the quality of literature， systematic review was performed by using RevMan 5.3 software. RESULTS A total of 14 studies involving 2 033 patients were included， of which 1 355 patients showed effective treatment outcomes. The meta-analysis results showed that Acute Physiology and Chronic Health Evaluation （APACHE）-Ⅱ ＞ 20 [OR＝4.50， 95%CI （2.28， 8.85）， P＜0.001]， malignant tumor [OR＝1.96， 95%CI （1.41， 2.72）， P＜0.001]， hemodialysis [OR＝2.09， 95%CI （1.40， 3.12）， P＜0.001]， septic shock [OR＝3.07， 95%CI （2.00， 4.72）， P＜0.001]， mechanical ventilation [OR＝2.31， 95%CI （1.57， 3.39）， P＜0.001]， coagulation dysfunction [OR＝ 3.03， 95%CI （2.09， 4.37）， P＜0.001]， glucocorticoids use＞3 days [OR＝2.26， 95%CI （1.14， 4.45）， P＝0.020]， and longer hospitalization time before using tigecycline [OR＝3.33， 95%CI （1.34， 8.30）， P＝0.010] were risk factors for the clinical efficacy of tigecycline in treatment of severe infections caused by MDR-GNB. Tigecycline initial double-dose regimen [OR＝0.23， 95%CI （0.13， 0.42）， P＜0.001]， combination therapy [OR＝0.15， 95%CI （0.05， 0.48）， P＝0.001]， and prolonged treatment course [OR＝0.91， 95%CI （0.88， 0.95）， P＜0.001] were protective factors. CONCLUSIONS There are many influential factors for the clinical efficacy of tigecycline in the treatment of severe infections caused by MDR-GNB， among which APACHE-Ⅱ score＞20， malignant tumor， hemodialysis， septic shock， mechanical ventilation， coagulation dysfunction， glucocorticoids＞3 d and longer hospitalization time before using tigecycline before tigecycline （No.20251606） use are risk factors； tigecycline double dose， combined medication and longer treatment course are protective factors.
