Background: and Purpose In patients with large vessel occlusion (LVO), intravenous thrombolysis (IVT) frequently alters thrombus location; however, the clinical impact of this phenomenon remains unclear. We aimed to compare post-IVT thrombus dynamics between tenecteplase and alteplase and to evaluate the association between thrombus dynamics and 3-month outcomes. Methods: This retrospective study analyzed prospectively collected, multicenter data from consecutive patients with LVO who underwent bridging therapy between January 2022 and December 2024. Thrombus dynamics were classified as resolution, migration, or stability. Analyses incorporated propensity score matching with weighting to balance baseline characteristics. Results: Of the 806 initially included patients, 746 were included after matching (373 treated with tenecteplase and 373 treated with alteplase). The incidence of thrombus migration was significantly higher in the tenecteplase group than in the alteplase group (19.3% vs. 11.3%; odds ratio [OR]: 1.92; 95% confidence interval [CI] 1.27–2.91). The advantage of tenecteplase over alteplase was restricted to patients with an IVT-to-puncture time of <60 minutes (18.6% vs. 6.2%; p=0.001) and was no longer significant when the interval ≥60 minutes (19.7% vs. 15.0%; p=0.204; pinteraction=0.043). Additionally, thrombus migration was associated with a better functional outcome (OR: 1.62; 95% CI 1.04–2.53). Finally, tenecteplase was associated with improved functional independence compared with alteplase (OR: 1.43; 95% CI 1.04–1.95). Conclusions Tenecteplase demonstrated superior efficacy in inducing thrombus migration compared with alteplase, particularly within 60 minutes of IVT administration. Thrombus migration independently predicted improved functional independence. These findings support the preferential use of tenecteplase for bridging therapy in patients with LVO.

Objective:To investigate the application value of flexible traction suspension (FTS) strategy in pure single-incision laparoscopic distal gastrectomy (PSILDG).Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 12 patients who underwent PSILDG in The Second Affiliated Hospital of Army Medical University from November 2021 to March 2024 were collected. There were 8 males and 4 females, aged (53±14)years. Observation indicators: (1) intraoperative conditions; (2) postoperative conditions; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M( Q1, Q3). Count data were described as absolute numbers. Results:(1) Intraoperative conditions. All 12 patients underwent PSILDG with FTS strategy successfully, with the operation time of (260±31) minutes, the volume of intraoperative blood loss of 103.3(37.5,150.0)mL, the length of surgical incision of (3.9±0.6)cm. There was no intra-operative special circumstance or complication. (2) Postoperative conditions. Results of histopatho-logical examination showed that among the 12 patients, there were 10 cases of adenocarcinoma, 1 case of signet ring cell carcinoma, and 1 case of high-grade intraepithelial neoplasia. The distance of the proximal tumor margin was 2.8(2.0,3.4)cm, the distance of distal margin was 5.9(5.0,7.5)cm, the tumor diameter was (2.3±1.0)cm, and the number of lymph node dissected was 34±10. On the post-operative first day, all 12 patients had a visual analog score of 1.0. The time to postoperative removal of gastric tube was 1.25(1.00,1.75)days, the time to postoperative first intake of liquid food was 2.00(1.00,2.00)days, the time to postoperative first out-of-bed activity was 1.67(1.00,2.00)days, the time to postoperative first flatus was 2.40(2.00,3.00)days, the time to postoperative first bowel movement was 3.50(2.00,5.00)days, the duration of postoperative hospital stay was (7.10±1.40) days, and the satisfaction score for the abdominal wall incision was 20.6±2.7. No patient experien-ced postopera-tive complications. (3) Follow-up. All 12 patients completed a 30-day follow-up after surgery, with no complication or need for secondary surgery.Conclusion:Application of FTS strategy in PSILDG is safe and feasible.

Objective To investigate the protective effect of β-glucan(BG)against intestinal ischemia reperfusion(II/R)injury by regulating the secretion of glucagon-like peptide-1(GLP-1).Methods Male C57BL/6 mice(6～8 weeks old)were subjected,and finally,the experiments had sham group,II/R group,II/R+BG group(0.1 mg/mL BG in drinking water for 2 weeks before modeling),II/R+liraglutide(LLT,GLP-1 analogue)group(0.2 μg/g LLT injected every 12 hours for 3 consecutive days before modeling),and II/R+BG+Ex9-39(GLP-1 R antagonist)group(intraperitoneal injection of 2 μg/g Ex9-39 1 h before modeling).After modeling,HE staining was used to observe intestinal morphological changes,and RT-qPCR and Western blotting were employed to evaluate the molecules(Occludin,ZO-1 and Claudin-1)related to intestinal barrier damage.The effect of 0.1 mg/mL BG treatment on the GLP-1 level in the serum and intestinal tissues of normal mice was determined with ELISA and immunofluorescence assay,respectively,and RT-PCR for the molecules related to GLP-1 expression(Gcg,Pcsk1/2,GIP and Foxa2).The effects of LLT and Ex9-39 pretreatment on intestinal morphology and intestinal barrier damage were also determined by morphological observation and expression levels of related molecules.Results II/R induced significant decreases in the mRNA levels of Occludin,ZO-1 and Claudin-1 and increase in Chiu's score when compared with sham control mice(P＜0.05).While,the mRNA levels of the 3 molecules were obviously higher and the Chiu's score was lower in the II/R+BG group than the II/R group(P＜0.05).BG pretreatment induced notably enhanced secretion of GLP-1 in the serum and intestinal tract of normal mice,and improved the mRNA expression of GLP-1-related molecules(P＜0.05).The intervention of GLP-1 analogue LLT could attenuate the II/R damage and decreased Chiu's score,with statistical difference in comparison with the II/R group(P＜0.05).GLP-1 receptor antagonist Ex9-39 reversed the protective effects of BG pretreatment against II/R damage,with notably differences in the expression of Occludin,ZO-1 and Claudin-1 and Chiu's score(P＜0.05).Conclusion BG can attenuate intestinal mucosal and functional injury after II/R by promoting intestinal GLP-1 secretion.

Objective To analyze the diversity and composition changes of gut fungal communities between patients with chronic kidney disease(CKD)and healthy controls.Methods A total of 8 CKD patients admitted in Department of Nephrology of our hospital,and another 5 age-and gender-matched healthy individuals were recruited in this study.Fresh fecal samples were collected from the CKD patients and healthy controls.ITS DNA sequencing was employed to determine the composition of intestinal fungi,and then bioinformatics analysis was applied to compare the differences in fungal community diversity,structure,and function between the 2 groups.Results There were no statistical differences between the 2 groups in terms of age,gender composition,BMI,and so forth.The results of Alpha diversity assessment showed statistical differences were observed in Simpson index and Shannon index in the intestinal fungi between the 2 groups(P＜0.01).So was in the Beta diversity between them(P＜0.01).The relative abundance of Candida was increased significantly(P＜0.01),while those of Cladosporium and Penicillium were decreased in the CKD group(P＜0.05).LEfSe analysis revealed that Candida was significantly enriched in CKD patients,whereas Cladosporium and Penicillium were significantly lower in abundance when compared to the healthy control group.Conclusion The composition of intestinal fungi in CKD patients is different from that in healthy individuals,exhibiting characteristic changes.Dysfunction of gut fungal flora may promote the progression of CKD.Regulating gut fungi and restoring gut microbiota homeostasis may become a new strategy for CKD treatment.

Background and Aims:N6-methyladenosine(m6A)epigenetic modification plays a crucial role in post-transcriptional gene expression regulation and various physiological and pathological processes,including tumorigenesis.The m6A reader IGF2BP2 significantly enhances mRNA stability and translation efficiency and is abnormally expressed in multiple cancers.However,the specific biological function of IGF2BP2 in pancreatic cancer remains unclear.Therefore,this study investigated the expression of the m6A reader IGF2BP2 in pancreatic cancer and its effects on pancreatic cancer cell functions.Methods:The expression levels of m6A-related writers,erasers,and readers were analyzed using The Cancer Genome Atlas(TCGA),the Genotype-Tissue Expression(GTEX)database,and the Gene Expression Omnibus(GEO).Kaplan-Meier survival analysis was conducted to assess the relationship between IGF2BP2 expression and the prognosis of pancreatic cancer patients.Immunohistochemistry was used to validate IGF2BP2 expression in clinical specimens of pancreatic cancer tissues and adjacent normal tissues.Functional experiments,including CCK-8 assay,flow cytometry for cell cycle analysis,colony formation assay,and Transwell migration assay,were performed to evaluate changes in cell proliferation,cell cycle distribution,colony formation ability,and migration capacity after IGF2BP2 knockdown in pancreatic cancer cells.Results:TCGA-GTEX and GEO database analyses showed that IGF2BP2 was highly expressed in pancreatic cancer tissues(both P<0.05)and that its high expression was associated with poor overall survival(both P<0.05).Immunohistochemical staining of clinical specimens confirmed that IGF2BP2 protein expression was higher in pancreatic cancer than in adjacent normal tissue.Functional experiments demonstrated that IGF2BP2 knockdown significantly reduced the proliferation ability of pancreatic cancer cells,arrested more cells in the G0-G1 phase,decreased colony formation,and impaired cell migration(all P<0.05).Conclusion:The m6A reader IGF2BP2 is highly expressed in pancreatic cancer tissues and is closely associated with poor prognosis in patients with this disease.Its mechanism of action may be related to the promotion of cancer cell growth and migration.

In recent years, significant progress has been made in the treatment of chronic constipation, with high-quality studies emerging in areas such as fecal microbiota transplantation (FMT), sacral neuromodulation (SNM), acupuncture, and surgical techniques. The therapeutic approach is shifting from a traditional "medication and surgery" model toward an integrated strategy that includes dietary and defecation habit adjustment, FMT, SNM, acupuncture, pharmacotherapy, and surgery. Although FMT can partially improve stool frequency and consistency, its standardization and long-term efficacy require further validation. SNM demonstrates limited effectiveness in treating chronic constipation and is relatively cost-inefficient. Electroacupuncture remains controversial, though some studies support its value. Biofeedback therapy is recommended by multiple guidelines as the first-line treatment for dyssynergic defecation (DD), with portable home-based biofeedback systems showing considerable potential. For internal rectal prolapse (IRP) and rectocele (RC), various surgical options exist without a clear superiority, though laparoscopic ventral rectopexy (VMR) is increasingly favored due to its low recurrence rate and high patient satisfaction. In the surgical management of slow transit constipation (STC), total colectomy with ileorectal anastomosis remains the mainstream approach, while subtotal colectomy is gaining attention as an alternative.

Objective:To evaluate the feasibility and preventive efficacy of a fascia- locking circular continuous suture ostomy technique in reducing parastomal hernia incidence.Methods:This technique was applied to patients undergoing permanent colostomy following radical rectal cancer resection. Surgical steps included: (1) A circular incision was made 1-2 cm medial to the intersection of the lateral margin of the rectus abdominis muscle and the line connecting the umbilicus to the left anterior superior iliac spine. Subcutaneous tissues were dissected vertically to expose the anterior rectus sheath, followed by blunt separation of the rectus abdominis after longitudinal incision of the sheath. The posterior rectus sheath and peritoneum were similarly incised. (2) Eight equidistant interrupted sutures (anchoring knots) were placed through the anterior rectus sheath, partial rectus abdominis, posterior rectus sheath, and peritoneum. (3) The terminal colon was exteriorized, and continuous sutures were applied to secure the anchoring knots and seromuscular layers of the bowel between knots, forming a circular locking mechanism by tying the terminal suture to the initial knot's tail. (3) The skin and seromuscular layers of the bowel margin were intermittently sutured (8-12 stitches) to achieve mucosal eversion.Results:From February to October 2023, 13 patients (11 males, 2 females; age: 67 ± 10 years; BMI: 23.8 ± 4.0 kg/m2) underwent this technique at the Second Affiliated Hospital of Army Medical University. Mean stoma creation time was 15.7 ± 3.0 minutes. During a follow-up of 14.6 ± 3.1 months, physical examinations and abdominal CT scans identified parastomal hernias in 2 male patients at 10 and 7 months postoperatively. Only one patient experienced a Clavien-Dindo grade ≥Ⅲ complication, which resolved with treatment. No stoma-related complications (e.g., infection, stenosis, or prolapse) occurred in any patient.Conclusion:The fascia-locking circular continuous suture ostomy technique is safe and feasible, demonstrating potential efficacy in preventing parastomal hernia following colostomy.
