Objective:To evaluate the clinical efficacy of endoclip papillaplasty (ECPP) for preventing recurrent choledocholithiasis after endoscopic retrograde cholangiopancreatography (ERCP).Methods:A retrospective analysis was conducted on 1 941 patients who underwent ERCP for choledocholithiasis in Henan Provincial People's Hospital from January 2019 to December 2023. A total of 250 patients who received ECPP were assigned to the ECPP group, while 251 matched controls were selected via 1∶1 year-stratified sampling into the control group. After follow-up, 209 ECPP cases and 190 controls were ultimately included in the analysis. Stone removal success rate, incidence of perioperative complications, and postoperative choledocholithiasis recurrence were compared between the two groups. Univariate and multivariate logistic regression were used to determine the risk factors for choledocholithiasis recurrence after ERCP.Results:Both groups achieved 100.0% stone removal success rate. There was no significant difference in the incidence of intraoperative perforation [0.5% (1/209) VS 1.1% (2/190), χ2=0.01, P=0.934], postoperative hyperamylasemia [21.5% (45/209) VS 17.4% (33/190), χ2=1.10, P=0.295] or post-ERCP pancreatitis [3.8% (8/209) VS 8.1% (9/190), χ2=0.20, P=0.653] between the ECPP group and the control group. The ECPP group showed significantly lower bleeding rate [5.1% (11/209) VS 12.3% (23/190), χ2=5.98, P=0.014] and choledocholithiasis recurrence rate [10.5% (22/209) VS 18.9% (36/190), χ2=5.68, P=0.017] compared with the control group. The multivariate logistic regression identified dilated common bile duct diameter ( OR=1.881, 95% CI: 1.101-3.213, P=0.021) as an independent risk factor for choledocholithiasis recurrence, while being female ( OR=0.482, 95% CI: 0.266-0.875, P=0.016) and ECPP ( OR=0.497, 95% CI:0.278-0.887, P=0.018) were protective factors. Conclusion:ECPP effectively reduces choledocholithiasis recurrence rate and bleeding risk after ERCP. ECPP and being female serve as protective factors for choledocholithiasis recurrence, while dilated bile duct diameter is an independent risk factor.

Objective:To evaluate the effect of extracorporeal shock wave on the phosphoproteomics of the spinal cord in rats with diabetic neuralgia.Methods:Thirty-six healthy male SPF-grade Sprague-Dawley rats, aged 2 months, weighing 200-250 g, were divided into 3 groups ( n=12 each) using the random number table method: control group (group C), diabetic neuralgia group (group D), and extracorporeal shock wave + diabetic neuralgia group (group E). The rats were continuously fed a common diet in group C, while the rats were fed a high-sugar and high-fat diet for 8 weeks in D and E groups. Streptozotocin 35 mg/kg was intraperitoneally injected, and the successful induction of diabetic neuralgia was defined as the blood glucose >14.6 mmol/L and the mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) ≤85% of baseline values. Group E received extracorporeal shock wave treatment after developing the model, with 1, 000 shocks per session at a frequency of 10 Hz and an energy of 1.0 bar, once per week for a total of 4 sessions. The MWT and TWL were measured before developing the model (T 0) and at 1, 2, 3 and 4 weeks after developing the model (T 1-T 4). After the last extracorporeal shock wave treatment, the rats were anesthetized and sacrificed, and lumbar spinal cord tissues were obtained for proteomic analysis and for detection of the expression of glial fibrillary acidic protein (GFAP), interleukin-1beta (IL-1β), and tumor necrosis factor-alpha (TNF-α) (by immunohistochemistry). Results:Compared with group C, the MWT and TWL were significantly decreased at T 1-T 4 in D and E groups ( P<0.05). Compared with group D, the MWT and TWL were significantly increased at T 1-T 4 in group E ( P<0.05). The results of phosphoproteomics screening revealed 284 differentially phosphorylated proteins in D and C groups, 282 in E and C groups, and 303 in E and D groups ( P<0.05). The results of immunohistochemistry showed that the expression of GFAP, IL-1β and TNF-α was significantly up-regulated in group D compared with group C ( P<0.05); the expression of GFAP, IL-1β and TNF-α was significantly down-regulated in group E compared with group D ( P<0.05). Conclusions:The mechanism by which extracorporeal shock wave alleviates diabetic neuralgia is related to inhibition of astrocyte activation and excessive phosphorylation of mGluR5 in rats.
