Objective:To investigate the practical value of pancreatic duct bind with supporting tube combined with single-needle suture for pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of 65 patients with pancreatic head or periampullary tumors who underwent LPD at the First Affiliated Hospital of Kunming Medical University between January 2021 and June 2024 were retrospectively analysed. Among them, 31 were male and 34 were female, aged (57.7±13.3) years. The patients were divided into two groups based on the method of pancreaticojejunostomy: 22 patients who underwent pancreatic duct bind with supporting tube single-needle suture pancreaticojejunos-tomy were included in the study group, 43 patients who underwent traditional pancreatic duct-to-mucosa pancreaticojejunostomy were included in the control group. The clinical data of the patients, including gender, age, operation time, pancreaticojejunostomy time, and postoperative complications, etc. were recorded.Results:Compared with the control group, the pancreaticojejunostomy time [(25.3±2.4) min vs. (47.0±3.9) min] and operation time [(425.2±52.1) min vs. (453.7±30.8) min] of the study group were both shortened, and the differences were statistically significant (both P<0.05). There was no statistically significant difference in the postoperative complication rate between the study group and the control group [18.2% (4/22) vs. 34.9% (15/43), P=0.161]. The incidence of clinically relevant pancreatic fistula in the study group was lower than that in the control group [4.5% (1/22) vs. 30.2% (13/43)], and the difference was statistically significant ( P=0.024). Conclusion:Pancreatic duct bind with supporting tube combined with single-needle suture pancreaticojejunostomy is safe and effective in LPD. Compared with traditional pancreatic duct-to-mucosa pancreaticojejunostomy, pancreatic duct bind with supporting tube combined with single-needle suture pancreaticojejunostomy has advantages in terms of clinically relevant pancreatic fistula rate, operation time, and pancreaticojejunostomy time.

Objective:To evaluate the safety and efficacy of secondary transport on extracorporeal membrane oxygenation (ECMO) for critically ill children.Methods:This was a retrospective cohort study. Data from 222 pediatric patients who underwent ECMO transport from May 2019 to May 2024 at 5 ECMO centers and Chinese Database of Pediatric Extracorporeal Life Support Organization were collected. The cases were divided into primary and secondary transport groups by nature of transport. The clinical data, including demographics, ECMO indications, transport distance, pre-transport lab results, prognosis and complications were analyzed. Two independent samples t-test, Wilcoxon test, and χ2 test or Fisher′s exact probability method were used to compare the differences between 2 groups and evaluate the safety and efficacy of secondary transport. Results:Among the 222 children transported with ECMO, there were 135 males and 87 females, with an age of 3.0 (0.2, 7.0) years. There were 202 cases in the primary transport group and 20 cases in the secondary transport group. All secondary transport patients had failed attempts at weaning ECMO before transfer. The patients in the secondary transport group were older, had higher rates of surgical cannulation, circulatory support, and pre-ECMO lactate levels compared to the primary transport group (7.0 (2.8, 10.0) vs. 3.0 (0.2, 6.0) years old, 55.0% (11/20) vs. 3.6% (7/202), 80.0% (16/20) vs. 41.6% (84/202), (10±4) vs. (7±6) mmol/L, Z=3.41, χ 2=66.31, 10.99, t=2.24, all P<0.05). In the secondary transport group, the vasoactive-inotropic scores of patients on circulatory support and the oxygenation index for patients requiring respiratory support were higher than those in the primary transport group (83±33 vs. 82±68, 51.0±1.8 vs. 37.4±10.2, t=2.36, 2.63, respectively; both P<0.05). There were no statistically significant differences between the 2 groups in sex, transport distance, pre-ECMO creatinine, arterial blood gas BE values, and ECMO duration (all P>0.05). No life-threatening complications occurred during the transport in either group. Two patients in the secondary transport group underwent heart transplantation, and 1 patient underwent radiofrequency ablation. The overall survival rate between the 2 groups showed no statistically significant difference (45.0% (9/20) vs. 55.4% (112/202), χ2=1.15, P>0.05). Conclusions:Secondary ECMO transport for critically ill children don't increase mortality or life-threatening complications during transport. ECMO patients who cannot receive effective treatment locally can benefit from secondary transport to an advanced ECMO center provides further treatment opportunities.

Objective:To discuss the ameliorative effect of total flavonoids from corn silk(TFCS)on kidney injury in the rats with urate nephropathy,and to clarify the possible mechanism.Methods:Sixty male Wistar rats were randomly divided into control group,model group,positive control group[benzbromarone(BZM)group,5 mg·kg-1·d-1],low dose of TFCS group(20 mg·kg-1·d-1),medium dose of TFCS group(40 mg·kg-1·d-1),and high dose of TFCS group(80 mg·kg-1·d-1),and there were 10 rats in each group.Except for control group,the rats in the other groups were administered potassium oxonate(350 mg·kg-1)and adenine(70 mg·kg-1)by gavage for 4 weeks to establish the hyperuricemic nephropthy models.The rats in different doses of TFCS groups were treated with TFCS for 2 weeks.Speckle blood flow imager was used to detect the renal blood perfusion of the rats in various groups and the kidney coefficients of the rats in various groups were caculated;HE staining and Masson staining were used to observe the pathomorphology and fibrosis degrees of kidney tissue of the rats in various groups and enzyme-linked immunosorbent assay(ELISA)method was used to detect the levels of uric acid(UA),creatinine(Cr),blood urea nitrogen(BUN),interleukin-6(IL-6),and tumor necrosis factor-α(TNF-α)in the serum and levels of β2-microglobulin(β2-MG)and microalbumin(ALB)in the urine of the rats in various groups;Western blotting method was used to detect the expression levels of urate transporter 1(URAT1),glucose transporter 9(GLUT9),and ATP-binding cassette transporter G2(ABCG2)proteins in kidney tissue of the rats in various groups.Results:Compared with control group,the renal blood perfusion volume of the rats in model group was significantly decreased(P<0.01).Compared with model group,the renal blood perfusion volumes of the rats in BZM group and low,medium,and high doses of TFCS groups were significantly increased(P<0.05 or P<0.01).Compared with control group,the kidney weight of the rats in model group was increased,with visible white granular spots on the surface,absence of blood color,and kidney volume was increased.Compared with model group,the kidney volumes of the rats in BZM group and medium and high doses of TFCS groups were decreased,with color tending toward that in control group,and the white granular spots on the surface were significantly reduced.Compared with model group,the kidney coefficients of the rats in BZM group and medium and high doses of TFCS groups were decreased(P<0.01).The HE staining results showed there were no abnormalities in kidney tissue structure in control group,while there were a small amount of brown-yellow urate crystal deposition and interstitial connective tissue hyperplasia in model group;compared with model group,the kidney tissue damage and inflammatory infiltration were alleviated to varying degrees in BZM group and different doses of TFCS groups.The Masson staining results revealed no obvious collagen fiber deposition in control group,whereas significant blue collagen fiber deposition in kidney tissue of the rats was found in model group,and the collagen volume fraction(CVF)was increased compared with control group(P<0.01);compared with model group,the CVFs of the rats in BZM group and different doses of TFCS groups were decreased(P<0.01).The ELISA results showed that compared with control group,the levels of UA,Cr,BUN,IL-6,and TNF-α in serum of the rats in model group were increased(P<0.01);compared with model group,the levels of UA,Cr,BUN,IL-6,and TNF-α in serum of the rats in BZM group and medium and high doses of TFCS groups were decreased(P<0.01).Compared with control group,the levels of β2-MG and ALB in urinary in model group were increased(P<0.01);compared with model group,the levels of β2-MG and ALB in urinary of the rats in different doses of TFCS groups were decreased(P<0.05 or P<0.01).The Western blotting results showed that compared with control group,the expression levels of URAT1 and GLUT9 proteins in kidney tissue of the rats in BZM group and model group were increased(P<0.01),while the expression level of ABCG2 protein was decreased(P<0.01).Compared with model group,the expression levels of URAT1 and GLUT9 proteins in kidney tissue of the rats in different doses of TFCS groups were decreased(P<0.05 or P<0.01),and the expression level of ABCG2 protein was increased(P<0.01).Conclusion:TFCS can significantly alleviate the kidney injury in the rats with urate nephropathy model,and its mechanism may be related to the downregulation of expression of URAT1 and GLUT9 proteins and upregulation of ABCG2 protein expression in kidney tissue.

Ovarian tumor (OT) is the most lethal form of gynecologic malignancy, with minimal improvements in patient outcomes over the past several decades. Metastasis is the leading cause of ovarian cancer-related deaths, yet the underlying mechanisms remain poorly understood. Psychological stress is known to activate the glucocorticoid receptor (NR3C1), a factor associated with poor prognosis in OT patients. However, the precise mechanisms linking NR3C1 signaling and metastasis have yet to be fully elucidated. In this study, we demonstrate that chronic restraint stress accelerates epithelial-mesenchymal transition (EMT) and metastasis in OT through an NR3C1-dependent mechanism involving nuclear protein 1 (NUPR1). Mechanistically, NR3C1 directly regulates the transcription of NUPR1, which in turn increases the expression of snail family transcriptional repressor 2 (SNAI2), a key driver of EMT. Clinically, elevated NR3C1 positively correlates with NUPR1 expression in OT patients, and both are positively associated with poorer prognosis. Overall, our study identified the NR3C1/NUPR1 axis as a critical regulatory pathway in psychological stress-induced OT metastasis, suggesting a potential therapeutic target for intervention in OT metastasis.

Alcoholic liver disease(ALD), a major cause of chronic liver disease worldwide, poses a serious threat to human health. Despite the availability of various drugs for treating ALD, their efficacy is often uncertain, necessitating the search for new therapeutic approaches. Traditional Chinese medicine polysaccharides have garnered increasing attention in recent years due to their versatility, high efficiency, and low side effects, and they have demonstrated significant potential in preventing and treating ALD. Emerging studies have suggested that these polysaccharides exert their therapeutic effects through multiple mechanisms, including the inhibition of oxidative stress and the regulation of lipid metabolism, gut microbiota, and programmed cell death. This review summarizes the recent research progress in the pharmacological effects and regulatory mechanisms of traditional Chinese medicine polysaccharides in treating ALD, aiming to provide a scientific basis and theoretical support for their application in the prevention and treatment of ALD.
