OBJECTIVES: To evaluate the protective effect of Schistosoma japonicum cystatin (rSj-Cystatin) in a mouse mode of "two-hit" sepsis. METHODS: Sixty male C57BL/6 mice randomized equally into sham-operated group, protein group, "two-hit" modeling group, and protein intervention group. In the former two groups, the mice received an intraperitoneal injection of 100 μL PBS followed by exposure of the cecum and then by intraperitoneal injection of 100 μL PBS or 25 μg rSj-Cystatin 30 min later; In the latter two groups, 100 μL PBS containing LPS (5 mg/kg) was injected intraperitoneally 24 h before cecal ligation and puncture (CLP), and 100 μL PBS or 25 μg rSj-Cystatin were injected 30 min after CLP. At 12 h after rSj-Cystatin treatment, 6 mice from each group were sacrificed for detection of TNF-α, IL-6, IL-10, TGF-β, iNOS and Arg-1 in the serum, spleen, liver, lung and kidney tissues using ELISA, for examinations of liver, lung and kidney pathologies with HE staining, and for analysis of CD3⁺CD4⁺CD25⁺Foxp3⁺ T cell percentage in the spleen using flow cytometry. The remaining mice were observed for general condition and 72-h survival. RESULTS: The 72-h survival rates in the 4 groups were 100%, 100%, 0% and 20%, respectively, showing significant differences between the latter two groups. The mouse models of "two-hit" sepsis exhibited obvious tissue pathologies and significant elevations of TNF-α and IL-6 in both the serum and tissue homogenate, which were significantly ameliorated by rSj-Cystatin treatment. Treatment with rSj-Cystatin also increased IL-10 and TGF-β levels and spleen CD3⁺CD4⁺CD25⁺Foxp3⁺ T cell percentage. The septic mouse models also showed increased iNOS levels in all the detected tissues and a decreased Arg-1 level in the kidney, and these changes were obviously improved by rSj-Cystatin treatment. CONCLUSIONS rSj-Cystatin has a protective effect against "two-hit" sepsis in mice by regulating the inflammatory microenvironment.

Objective:To explore the effect of hyperthermic intraperitoneal chemotherapy (HIPEC) on postoperative immune function and tumor marker levels in patients with advanced gastric adenocarcinoma.Methods:A prospective cohort study was conducted, enrolling 72 patients with stage ⅢA-ⅢC gastric adenocarcinoma admitted to Jinjiang Hospital from August 2022 to December 2023. Patients were divided into the HIPEC group ( n=36, radical resection+ HIPEC within 3 days after surgery) and the control group ( n=36, radical resection alone) using the random number table method. The HIPEC protocol was perfusion with raltitrexed (4 mg in 4, 000 ml normal saline, at 43 ℃) for 60 minutes. Peripheral blood immune cells (CD3 +, CD4 +, CD8 +, CD4 + /CD8 + ratio) before treatment and 7 days after treatment, and serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), and carbohydrate antigen 72-4 (CA72-4) 30 days after treatment were compared between the two groups. Results:Before treatment, there were no statistically significant differences in CD3 +, CD4 +, CD8 +, or CD4 + /CD8 + levels between the two groups (all P>0.05). Seven days after treatment, the HIPEC group had higher levels of CD3 +, CD4 +, and CD4 + /CD8 + ratio, and a lower CD8 + level than the control group, with statistically significant differences (all P<0.05). Before treatment, there were no significant differences in CEA, CA19-9, or CA72-4 levels between the two groups (all P>0.05). Thirty days after treatment, the HIPEC group had lower levels of CEA, CA19-9, and CA72-4 than the control group, with statistically significant differences (all P<0.05). Conclusions:HIPEC can significantly improve the postoperative immune function of patients with advanced gastric adenocarcinoma (by increasing the CD4 + /CD8 + ratio and immune cell activity) and effectively reduce tumor marker levels, which may provide a new strategy for preventing postoperative recurrence.

Objective:To evaluate the long-term effectiveness of lingual mucosal graft ureteroplasty (LMGU) for managing long-segment (≥5 cm) ureteral strictures in a multi-institutional cohort of patients.Methods:A multi-center retrospective case series study was conducted on clinical data from 42 patients undergoing LMGU for long-segment ureteral strictures (≥5 cm) across five institutions between February 2017 and June 2024. The cohort comprised 31 males and 11 females, with an age of (43.4±12.0) years (range: 15 to 64 years) and a body mass index of (24.6±2.6) kg/m2 (range: 16.0 to 30.0 kg/m2). Strictures involved the left ureter in 24 cases and right ureter in 18 cases, demonstrating a stricture length of (6.4±1.5) cm (range: 5.0 to 11.5 cm). Surgical interventions included either onlay ureteroplasty or augmented anastomotic ureteroplasty, selected according to intraoperative findings. Intraoperative parameters, postoperative complications, and follow-up outcomes were analyzed.Results:Laparoscopic surgery was performed in 22 cases and robot-assisted surgery in 20 cases. Among the 42 patients, 22 underwent onlay ureteroplasty while 20 received augmented anastomotic ureteroplasty. The graft length was (5.9±1.8) cm (range: 3.0 to 12.0 cm), operative time (191.5±55.6) minutes (range: 105.0 to 350.0 minutes), and intraoperative estimated blood loss (86.7±73.6) ml (range: 10.0 to 400.0 ml). All procedures were successfully completed without conversion to open surgery. The postoperative hospital stay was (7.6±2.0) days (range: 4.0 to 15.0 days), with double-J stent removal at 6 to 8 weeks postoperatively. During a follow-up of (49.1±25.0) months (range: 12.0 to 99.0 months), no stricture recurrence was observed in any patient.Conclusion:LMGU is a safe, feasible, and effective long-term technique for managing long-segment (≥5 cm) ureteral strictures.
