Objective:To investigate the clinicopathological features, genetic characteristics, and differential diagnosis of glomangiomatosis with uncertain malignant potential.Methods:Two cases of glomangiomatosis with uncertain malignant potential were collected at Henan Provincial People′s Hospital from 2013 and 2023. Immunohistochemistry and next generation sequencing (DNA-seq) were used to detect the related protein and gene variation. Patients were followed up.Results:Case 1 was male, 34 years old; and case 2 was female, 28 years old. Both had tumor recurrence in the original site. There were multiple nodules at right calf and ankle, involving superficial subcutaneous tissue and deep interfascicular muscles; some nodules were borderless and painful. Microscopically, the tumor was nodular with fibrous pseudocapsule, some had indistinct borders and diffuse infiltration to the surrounding adipose tissue. The tumor cells were round to ovoid with inconspicuous nucleoli, partly surrounding small irregularly dilated thin-walled blood vessels. The recurrent tumors showed epithelioid morphology in some of the tumor cells, with eosinophilic cytoplasm, some apparent nucleoli, mild to moderate nuclear atypia, and brisk mitotic figures. Focally, perimuscular cell differentiation was noted. The small lesion showed intravascular tumor thrombus. NGS revealed BRAF V600E mutation in case 1, and BRAF V600E mutation combined with PDGFRB gene amplification in case 2.Conclusions:Glomangiomatosis with uncertain malignant potential is a rare variant of glomus tumor. It has a unique growth pattern morphologically, BRAF V600E mutation, and invasive biological behavior.

Objective:To evaluate the feasibility of " two-stitch" fashion in laparoscopic pancreaticojejunostomy (PJ) for patients with fine pancreatic duct (<3 mm).Methods:Clinical data of 32 patients with pancreatic duct diameter <3 mm undergoing laparoscopic PJ using the " two-stitch" fashion between Apr 2021 and Jun 2024 were retrospectively analyzed, including 20 males and 12 females, aged (61.2±23.7) years. Among the patients, there were 23 (71.9%) patients of periampullary tumor and 9 (28.1%) of central pancreatic tumor. 23 (71.9%) patients underwent laparoscopic pancreatoduodenectomy (LPD) and nine (28.1%) underwent laparoscopic central pancreatectomy (LCP). All patients underwent the " two-stitch" fashion of laparoscopic PJ (one stitch each on the ventral and dorsal sides of pancreas for duct-to-mucosal anastomosis). The operation time, PJ time, postoperative hospital stay, postoperative complications (pancreatic fistula, gallbladder leakage, abdominal cavity infection, etc) and mortality were recorded.Result:All patients underwent the " two stitch" laparoscopic PJ successfully, 23(71.9%) patients underwent laparoscopic pancreatoduodenectomy (LPD) and nine (28.1%) underwent laparoscopic central pancreatectomy (LCP). The operation time was (279.3±115.8) min, the PJ time was (31.9±12.2) min, and the postoperative hospital stay was (13.4±8.3) d. Grade B pancreatic fistula occurred in six cases (18.8%, four of LPD and two of LCP), delayed gastric emptying in one case of LPD (3.1%), abdominal infection in three cases (9.4%, two of LPD and one of LCP), biliary fistula in two cases (6.3%, LPD). There were no grade C pancreatic fistula. All patients with postoperative complications were managed with conservative treatment.Conclusion:Laparoscopic " two stitch" PJ for patients with fine pancreatic duct (<3 mm) is safe and feasible.

Objective To explore the mechanism by which the sanguis draconis flavones(SDF)regulates the reactive oxygen species(ROS)/thioredoxin-interacting protein(TXNIP)pathway to mediate cell pyroptosis and improve cerebral ischemia-reperfusion injury(CIRI)in rats.Methods The experimental rats were randomly divided into the control group(Ctrl),the CIRI group,the low-dose SDF group(SDF-L),the high-dose SDF group(SDF-H),and the SDF-H+ROS/TXNIP pathway activator,trimethylamine oxide(TMAO)group(SDF-H+TMAO).Among them,except for the control group,the remaining rats all needed to establish the CIRI rat model by the modified suture method.Zea Longa scoring was performed on rats from each group.ELISA was used to detect the levels of serum inflammatory factors interleukin(IL)-1β,IL-18 and oxidative stress-related factors superoxide dismutase(SOD),malondialdehyde(MDA),glutathione peroxidase(GSH-Px).Flow cytometry was used to measure the ROS levels.Cerebral edema was detected.Cerebral infarction was detected by 2,3,5-triphenyl tetrazolium chloride(TTC)staining.HE staining was used to detect the pathological changes of brain tissue.Immunohistochemistry was used to detect the expression of pyrolytic effector protein dermolin D(GSDMD).Western blotting was used to detect the expression of proteins related to the ROS/TXNIP pathway.Results Compared with the control group,a large area of cerebral infarctions were observed in the brain tissue of the CIRI group,accompanied by mild hemorrhage and obvious infiltration of inflammatory cells.Neuronal cells underwent degeneration and necrosis,with sparse and disordered arrangement.The phenomena of nuclear condensation and nucleolus lysis were obvious.The Zea Longa score,cerebral infarction volume,brain tissue water content,levels of IL-1β,IL-18,ROS,MDA,and the expressions of GSDMD,TXNIP,nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3),apoptosis-related punctate protein(ASC),and Caspase-1 increased,while the activities of SOD and GSH-Px decreased(P＜0.05).Compared with the CIRI group,the pathological damage of brain tissues in the SDF-L group and the SDF-H group was significantly improved.The Zea Longa score,cerebral infarction volume,brain tissue water content,levels of IL-1β,IL-18,ROS,MDA,and the expressions of GSDMD,TXNIP,NLRP3,ASC,and Caspase-1 decreased.The activities of SOD and GSH-Px increased(P＜0.05);TMAO treatment partially reversed the improvement effect of SDF on CIRI in rats.Conclusion SDF ameliorates cerebral CIRI in rats by inhibiting ROS/TXNIP pathway-mediated pyroptosis.

Neuraxial opioids, widely used in obstetric and perioperative pain management, often lead to unwanted itch, reducing patient satisfaction. While the μ-opioid receptor has been implicated in opioid-induced itch, the genetic basis for variable itch incidence remains unknown. This study examined 3616 patients receiving epidural opioids, revealing an itch occurrence of 26.55%, with variations among opioid types and gender. Analysis of the OPRM1 gene identified six single-nucleotide polymorphisms, notably rs1799971 (A118G), that correlated with opioid-induced itch. Mouse models with an equivalent A112G mutation showed reduced neuraxial opioid-induced itch and light touch-evoked itch, mirroring human findings. The 118G allele demonstrated an anti-itch effect without impacting analgesia, addiction, or tolerance, offering insights for risk stratification and potential anti-itch pretreatment strategies.
