ObjectiveTo investigate the effect of solute carrier family 7 member 5 (SLC7A5) inhibitor JPH203 on renal fibrosis induced by unilateral ureteral obstruction in mice. MethodsSixteen SPF male C57BL/6 mice were randomly divided into the control group and the experimental group, with 8 mice in each group. The mouse model of renal fibrosis was established by unilateral ureteral obstruction. From the third day after surgery, the mice in the control group were intraperitoneally injected with phosphate-buffered saline (PBS) for 11 consecutive days, and the injection dose was 200 μL/d. Mice in the experimental group received intraperitoneal injection of JPH203 (50 mg/kg) every day for 11 days. On day 14, the mice were euthanized, then the kidney tissues were obtained. Hematoxylin and eosin (HE) staining was used to assess renal tissue damage, Masson staining was used to evaluate collagen fiber deposition in the extracellular matrix, and immunohistochemistry was used to detect the levels of fibroblast activation markers α-smooth muscle actin (α-SMA) and collagen type Ⅰ (COL-Ⅰ) in kidney tissues. Western blotting was further performed to measure the expression levels of SLC7A5 and transforming growth factor-β1 (TGF-β1), as well as the phosphorylation levels of mammalian target of rapamycin complex 1 (mTORC1) signaling pathway-related molecules. Real-time quantitative PCR was used to verify changes in the mRNA levels of SLC7A5, α-SMA, and COL-Ⅰ in kidney tissues. ResultsCompared with the control group, the experimental group showed reduced destruction of renal tissue structure and a significantly lower pathological injury score (P<0.05). Additionally, collagen deposition in the extracellular matrix was decreased, and the percentage of collagen fiber area was significantly reduced (P<0.001) in the experimental group. The levels of fibroblast activation markers α-SMA and COL-Ⅰ were significantly lower in the experimental group (both P<0.001). The expression levels of SLC7A5 and TGF-β1 were also significantly decreased (P<0.001), and the phosphorylation levels of mTORC1 signaling pathway-related proteins 4E-BP1 and mTORC1 were significantly reduced (P<0.001). Real-time quantitative PCR confirmed that the mRNA levels of SLC7A5, α- SMA, and COL-Ⅰ in kidney tissues were significantly lower in the experimental group (P<0.001). ConclusionJPH203 may inhibit the progression of renal fibrosis in mice by suppressing SLC7A5 expression, regulating the mTORC1 signaling pathway, and altering fibroblast activation status.

Gastric cancer with peritoneal metastasis (GCPM) is a common and lethal manifestation of advanced gastric cancer, with a median survival of only 5-11 months. This consensus was developed by 30 experts from Asia (China, Japan, Korea, and Singapore) using the Delphi method and the GRADE evidence grading system. A total of 29 statements were formulated, covering the diagnosis and assessment of GCPM, indications for laparoscopic exploration and NIPS (normothermic intraperitoneal and systemic treatment), treatment regimens, prevention and management of complications, criteria for conversion surgery, and postoperative intraperitoneal therapy. The consensus aims to standardize clinical practice and improve the prognosis of patients with GCPM.

BACKGROUND: Spicy food consumption has been reported to be inversely associated with mortality from multiple diseases. However, the effect of spicy food intake on the incidence of vascular diseases in the Chinese population remains unclear. This study was conducted to explore this association. METHODS: This study was performed using the large-scale China Kadoorie Biobank (CKB) prospective cohort of 486,335 participants. The primary outcomes were vascular disease, ischemic heart disease (IHD), major coronary events (MCEs), cerebrovascular disease, stroke, and non-stroke cerebrovascular disease. A Cox proportional hazards regression model was used to assess the association between spicy food consumption and incident vascular diseases. Subgroup analysis was also performed to evaluate the heterogeneity of the association between spicy food consumption and the risk of vascular disease stratified by several basic characteristics. In addition, the joint effects of spicy food consumption and the healthy lifestyle score on the risk of vascular disease were also evaluated, and sensitivity analyses were performed to assess the reliability of the association results. RESULTS: During a median follow-up time of 12.1 years, a total of 136,125 patients with vascular disease, 46,689 patients with IHD, 10,097 patients with MCEs, 80,114 patients with cerebrovascular disease, 56,726 patients with stroke, and 40,098 patients with non-stroke cerebrovascular disease were identified. Participants who consumed spicy food 1-2 days/week (hazard ratio [HR] = 0.95, 95% confidence interval [95% CI] = [0.93, 0.97], P <0.001), 3-5 days/week (HR = 0.96, 95% CI = [0.94, 0.99], P = 0.003), and 6-7 days/week (HR = 0.97, 95% CI = [0.95, 0.99], P = 0.002) had a significantly lower risk of vascular disease than those who consumed spicy food less than once a week ( Ptrend <0.001), especially in those who were younger and living in rural areas. Notably, the disease-based subgroup analysis indicated that the inverse associations remained in IHD ( Ptrend = 0.011) and MCEs ( Ptrend = 0.002) risk. Intriguingly, there was an interaction effect between spicy food consumption and the healthy lifestyle score on the risk of IHD ( Pinteraction = 0.037). CONCLUSIONS Our findings support an inverse association between spicy food consumption and vascular disease in the Chinese population, which may provide additional dietary guidance for the prevention of vascular diseases.

Objective:To compare the efficacy of body posture combined with pharmacotherapy and pharmacotherapy alone in the treatment of chronic subdural hematoma(CSDH).Methods:Firstly, retrospective case series study was conducted. Thirty cases of CSDH that had received body posture combined with pharmacotherapy at Department of Neurosurgery, Huashan Hospital Affiliated to Fudan University from December 2016 to October 2020 were studied retrospectively. Twenty-seven patients were male, and 3 patients were female. The age of patients ( M(IQR)) was 66(16) years (range:28 to 84). Nineteen patients had unilateral hematoma, and 11 patients had bilateral hematoma. All patients received pharmacotherapy and body posture therapy that was to raise their lower limbs 20 to 30 cm with leg lift pad and get abdominal compressed with customized abdominal belt in supine position. Patients were required to maintain the body posture as much as possible, with the maximum to 16 to 18 hours per day. Patients with unilateral hematoma should tilt the head to the affected side and avoid tilting it to the opposite side. For patients with bilateral hematoma, there was no need for head lateralization. Patient were treated with oral dexamethasone and atorvastatin simultaneously. The preliminary efficacy of body posture combined with pharmacotherapy was determined by hematoma improvement rate which was analyzed by Clopper-Pearson method. Then, the multi-center, prospective, randomized controlled trial had carried out in 9 medical centers from August 2020 to November 2021. The stratified block randomization method was adopted. Patients were randomized in a ratio of 1∶1 to either receive pharmacotherapy alone(the control group) or body posture combined with pharmacotherapy(the experiment group) for 3 months and followed up for 6 months. Effective treatment was defined as complete absorption of hematoma, or the hematoma volume decreased by more than 10 ml and Markwalder grading scale score had improved by more than 1 point compared to the baseline. The efficacy rate and surgery conversion rate at 3 months and recurrence at 6 months were observed. Comparison between groups was performed with paired sample t test, Mann-Whitney U test, χ2 test, corrected χ2 test, or Fisher exact probability method. Logistic regression was used to compare the effective rate and operation rate between the two groups. Results:In the respective study, 30 patients completed follow-up 13 to 353 days after treatment. At the last follow-up, the incidence of almost complete absorption or significantly absorption of hematoma (hematoma volume was significantly reduced accompanied by symptom improvement) was 93.3%. The 95% CI for the incidence that analyzed by the Clopper-Pearson method was 77.9% to 99.2%. One hundred and six patients were enrolled in the multicenter study. Fifty-five patients underwent body posture combined with pharmacotherapy. The age was 74(17) years (range:26 to 92). Thirty-nine patients were males and 16 were females. Fifty-one patients underwent pharmacotherapy alone. The age was 69(12) years (range:48 to 84). Thirty-seven patients were males and 14 were females. The length of body posture recorded in diary card was (15.7±2.3) hours(range:7.6 to 19.3 hours). The efficacy rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 83.6% (46/55) and 56.9% (29/51), respectively at 3 months. The result of the logistic regression analysis showed that the efficacy of body posture combined with pharmacotherapy group was better than that of pharmacotherapy alone group ( OR=3.88,95% CI:1.57 to 9.58, P=0.003). Surgery rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 5.5% (3/55) and 21.6% (11/51) respectively. The result of Logistic regression showed that the pharmacotherapy alone group was more likely to be converted to surgery ( OR=0.21,95% CI:0.05 to 0.80, P=0.023). At the 6 months, no recurrence of cases was found in the body posture combined with pharmacotherapy group. However, the recurrence rate of pharmacotherapy alone group was 6.3% (3/48), there was no significant difference between the two groups ( P>0.05). Conclusion:The effect of body posture combined with pharmacotherapy for chronic subdural hematoma is better than that of pharmacotherapy alone.

Objective:To evaluate the effectiveness of splenic circulation control technology in minimally invasive radical resection surgery for pancreatic neck/body cancer.Methods:This is a retrospective case series study. Retrospective analysis of clinical data of 12 patients who underwent laparoscopic or robotic radical resection for pancreatic neck/body cancer at the Department of Gastrointestinal and Pancreatic Surgery,Zhejiang Provincial People′s Hospital between January 2024 and January 2025. There were 7 males and 5 females,with mean age of 68 years (range: 52 to 79 years). Clinical data including preoperative,intra-operative and postoperative outcomes were analyzed. Postoperative follow-up was conducted via outpatient visits and telephone interviews,with the follow-up ending on April 1,2025.Results:All 12 patients underwent minimally invasive radical resection of pancreatic neck/body cancer using splenic circulation control technology,consisted of 3 laparoscopic and 9 robotic procedures. The mean operative time was 185 minutes (range: 140 to 315 minutes),and the average blood loss was 100 ml (range: 30 to 300 ml). Two cases involved combined organ resection.There was no conversion to open surgery. Postoperative complications were observed in 2 patients. One patient developed grade B pancreatic leakage,managed by ultrasound-guided puncture.The patient was discharged with drainage tube. The other patient experienced chylous leakage,recovered with conservative treatment. No delayed gastric emptying,hemorrhage or reoperations were observed. The median postoperative hospital stay was 13 days (range: 8 to 20 days).Conclusion:The splenic circulation control technique is simple and safe,and shows certain application prospects in minimally invasive radical resection of pancreatic neck and body cancer.

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.

The clinical data of a child with refractory systemic juvenile idiopathic arthritis (sJIA) who was admitted to the Children′s Hospital, Zhejiang University School of Medicine in October 2023 were analyzed, and literature review was conducted.The patient was a 9-year-old boy, who was admitted due to recurrent fever, accompanied by rash and joint pain for more than 4 years.Four years ago, he was diagnosed with macrophage activation syndrome and sJIA.In the past 4 years, the condition recurred 3 times under treatment with glucocorticoids, Cyclosporine, and Methotrexate.He previously experienced allergic shock after 5 minutes of infusion of Tocilizumab.Due to Tocilizumab allergy, he was treated with Janus kinase inhibitors, but the disease still recurred.After informed consent was obtained from the guardian, 240 mg of Tocilizumab was administrated for desensitization once every 2 weeks and the process went smoothly.The patient has been followed up for more than 6 months and no allergic reactions had occurred.The condition was well controlled, and the Prednisone acetate tablet had been reduced to 2.5 mg orally once a day.At present, there are 10 patients undergoing desensitization treatment both domestically and internationally, including 2 males and 8 females, aged between 2.5 and 54.0 years.All of them have achieved a success in desensitization.Therefore, Tocilizumab desensitization therapy is of great significance for patients who are allergic to biologics in clinical practice.

Objective:To explore the clinical features and risk factors for pediatric severe Mycoplasma pneumoniae pneumonia (SMPP) complicated with pulmonary embolism. Methods:SMPP patients admitted to Department of Pediatrics, Jiaxing First Hospital and Pediatric Intensive Care Unit, Shanghai Children′s Hospital from December 2019 to December 2023 were included in this retrospective case-control study.According to whether they were complicated with pulmonary embolism, SMPP patients were divided into a pulmonary embolism group and a non-pulmonary embolism group.Clinical characteristics of the two groups, including general data, laboratory examination and imaging data were compared and analyzed.The t-test and Mann-Whitney rank-sum test were used to compare the measurement data, and the χ2 test was used to compare the count data.The risk factors of SMPP patients developing pulmonary embolism were analyzed by the univariate method. Results:There were 10 out of 62 SMPP children developing pulmonary embolism, showing an incidence of 16.13%.In the pulmonary embolism group, there were 5 boys and 5 girls, with a median age of 7.50 (5.75, 9.25) years.There were 52 children in the non-pulmonary embolism group, including 29 boys and 23 girls, with a median age of 6.50(5.00, 8.00)years.The hospitalization time, body temperature, total white blood cell count, neutrophil count, C-reactive protein levels, lactate dehydrogenase levels, prothrombin time, activated partial thromboplastin time, D-dimer (D-D) levels, fibrinogen degradation product levels, pleural effusion and atelectasis rates in the pulmonary embolism group were significantly higher than those in the non-pulmonary embolism group (all P<0.05). Fibrinogen levels in the pulmonary embolism group were significantly lower than those in the non-pulmonary embolism group ( P<0.05). Univariate Logistic regression analysis showed that the D-D level was a risk factor for SMPP patient developing pulmonary embolism.The receiver operating characteristic curve analysis revealed that the D-D level had the largest area under the curve for predicting pulmonary embolism of 0.990(95% CI: 0.972-1.000, P<0.001), with a sensitivity of 100%, a specificity of 92%, and a cut-off value of 4.63 mg/L. Conclusions:SMPP children complicated with pulmonary embolism are prone to high inflammation and impaired coagulation function.The increase of D-D levels is a risk factor for the development of pulmonary embolism in SMPP.
