Objective:To evaluate the safety and efficacy of laparoscopes adhesiolysis in the treatment of adhesive intestinal obstruction.Methods:A retrospective analysis was conducted on the clinical data of 30 patients with adhesive intestinal obstruction who underwent laparoscopes adhesiolysis at the First Affiliated Hospital, Zhejiang University School of Medicine between January 2021 and December 2024. The demographics, surgical parameters and postoperative complications were recorded.Results:Among the 30 patients, 16 were male and 14 were female, with age of (55.93 ± 13.83) years. A history of abdominal surgery was present in 25 patients (83.3%). Of the surgeries, 4 cases (13.3%) were performed as emergency procedures and 26 cases (86.7%) were elective. The operative time was (125.57 ± 48.25) min, and intraoperative blood loss was (26.17 ± 16.90) ml. The time to first flatus was (3.30 ± 1.95) d, the time to first oral intake was 4.00 (3.00, 5.00) d, the hospital stay was (24.23 ± 17.97) d, and the postoperative hospital stay was 11.50 (6.75, 18.75) d. The incision pain score 0 score was in 8 cases (26.7%), 1 score in 5 cases (16.7%), 2 scores in 10 cases (33.3%), 3 scores in 3 cases (10.0%), 4 scores in 3 cases (10.0%), and 5 scores in 1 case (3.3%). One case developed a postoperative wound infection. The patients were followed up for 1 year, 1 patient experienced recurrent incomplete intestinal obstruction due to widespread peritoneal metastasis from gastric cancer.Conclusions:Laparoscopes adhesiolysis is a safe and effective treatment for adhesive intestinal obstruction, offering advantages in terms of postoperative recovery and low complication rates. The continued use of minimally invasive techniques is recommended in the management of this condition.

Purpose:
This study aimed to investigate the prognostic value of lymph node ratio (LNR) in patients with locally advanced gastric cancer who received neoadjuvant chemotherapy.
Materials and Methods:
We retrospectively enrolled gastric cancer patients treated with neoadjuvant chemotherapy and curative surgery at the First Affiliated Hospital of Zhejiang University from 2004 to 2015 as the study cohort. Patients with the same inclusion criteria treated in 2016–2017 were enrolled as the validation cohort. Kaplan-Meier curves were assessed using the log-rank test to analyze the differences in overall survival (OS).Multivariate survival analysis was performed using the Cox proportional hazards model.The areas under the receiver operating characteristic curve of ypN and LNR categories for predicting the actual 3-year OS were compared.
Results:
A total of 265 patients were included in the proposal cohort. The median number of retrieved lymph nodes (rLNs) was 32. The number of positive lymph nodes (pLNs) increased as rLN increased (P=0.037), but the LNR remained relatively constant (P=0.462). The LNR was categorized into 4 groups according to the prognosis: ypNr0, node-negative with rLN>25; ypNr1, node-negative with rLN≤25 or 0

Objective To investigate the clinical efficacy of neoadjuvant chemotherapy combined with radical gastrectomy for advanced gastric cancer.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 73 patients who underwent neoadjuvant chemotherapy combined with radical gastrectomy for advanced gastric cancer at the First Affiliated Hospital of Zhejiang University between June 2004 and December 2009 were collected.Neoadjuvant chemotherapy regimens included XELOX and FOLFOX.Patients received radical gastrectomy within 2 weeks after the completion of the last cycle of neoadjuvant chemotherapy and then continued to undergo postoperative neoadjuvant chemotherapy.Observation indicators:(1) adverse event of neoadjuvant chemotherapy;(2) surgical and postoperative situations;(3) follow-up situations.Follow-up using outpatient examination and telephone interview was performed to detect survival of patients up to December 2014.Measurement data with skewed distribution were described as M (range).Overall survival time was from the beginning of treatment to death or end of follow-up (patients with loss to follow-up).Progression-free survival time was from the beginning of treatment to tumor progression,recurrence and metastasis or death.The survival curve was drawn by the Kaplan-Meier method.Results (1) Adverse event of neoadjuvant chemotherapy:of 73 patients,38 received XELOX regimens and 35 received FOLFOX regimens,with a median cycle of 3 (range,1-7 cycles).There were 55 adverse events during neoadjuvant chemotherapy,including 47 with grade 1-2 and 8 with grade 3-4.(2) Surgical and postoperative situations:all the 73 patients underwent successful D2 radical gastrectomy for gastric cancer,including 40 receiving total gastrectomy,31 receiving distal gastrectomy,1 receiving total gastrectomy with transverse colon resection and 1 receiving distal gastrectomy with cholecystectomy.Of 73 patients,10 with postoperative complications were improved by conservative treatment,including 3 with pleural effusion,2 with peritoneal effusion,2 with anastomotic bleeding,2 with cholecystitis and 1 with lympha fistula.No patient received reoperations or died within 30 days postoperatively.Pathological TNM staging:22 patients were detected in stage Ⅰ-Ⅱ,45 in stage Ⅲ,4 in stage Ⅳ and 2 in stage T0N1M0.Three patients (in stage T0N0M0) had complete remission.Forty-three patients underwent postoperative chemotherapy.(3) Followup:all the 73 patients were followed up for 8-125 months,with a median time of 51 months.The median survival time,5-year overall survival rate and 5-year disease-free survival rate of 73 patients were 52 months,41.1% and 34.2%,respectively.Conclusion XELOX and FOLFOX regimens of neoadjuvant chemotherapy combined with radical gastrectomy for advanced gastric cancer are safe and effective.

Standard therapy has not been established for thyroid cancer when a thyroidectomy is contraindicated due to systemic disease. Herein, we reported a patient who had hypertrophic cardiomyopathy and papillary thyroid carcinoma treated by radiofrequency ablation because of inability to tolerate a thyroidectomy. Radiofrequency ablation can be used to treat thyroid cancer when surgery is not feasible, although the long-term outcome needs further observation.

AIM:To investigate ischemia reperfusion (I/R)-induced proteomic changes in rat skeletal muscle. METHODS: Healthy male Wistar rats were randomly divided into two groups as follows (n=6): sham group and I/R group. I/R of right hind limb was induced by 4 h ischemia followed by 24 h reperfusion. The 2-DE was applied to separate the proteins extracted from skeletal muscle tissue at the end of experiment, followed by Coomassie Brillant blue R-250 staining. Computer image analysis was used to determine the differential expression of proteins between the two groups, and 7 protein spots expressed differentially were picked out and subjected to in-gel digest and MALDI-TOP for identification. RESULTS: 354?13 proteins were detected and the match rate was (78.7?1.4)%. 10 proteins displayed significant changes after I/R, of which, 6 proteins increased and 3 proteins decreased in expression. Moreover, 2 spots in I/R group were observed, only 1 spots of which in control. 5 proteins were identified after mass spectrometry. Mitochondrial aldehyde dehydrogenase (ALDH) precursor, heat shock 27 kD protein (HSP27), an unnamed protein product (increased in I/R group), ?-actin (decreased in I/R group), and nuclear transport factor 2 (NTF-2) W7a mutant were found in I/R group. CONCLUSION: I/R injury induced differential proteomic changes in rat skeletal muscle. ALDH, ?-actin and HSP27 expression, and NTF-2 mutation are involved in I/R injury.

AIM: To test the effects of FTY720 on mouse intestinal allografts.METHODS: C_3H mice(H-2~k)were used as donor and C57BL/6 mice(H-2~b) as recipients.FTY720 group,allogeneic control group and isogeneic control group were set up.6 and 14 days after transplantation,murine intestinal grafts were harvested for histologic assessment.Lymphocytes were collected from mesenteric lymph nodes(MLN),Peyer's patch(PP),lamina propria lymphocytes(LPL) and intraepithelial lymphocytes(IEL) in the graft,then were analyzed by cytometry.RESULTS: Rejection was inhibited in FTY720 group at the 6th post-transplant day,although not at the 14th day.Recipient CD4~+ and CD8~+ T cells,CD19~+ B cells,as well as ?? TCR lymphocytes,were greatly reduced by FTY720 therapy.The similar action of FTY720 was also revealed in Gr1~+CD11b~+ monocytes.CONCLUSION: FTY720 is efficient on alleviating allo-immune response by reducing the infiltration of both lymphocytes and monocytes into the graft in a mouse intestinal transplantation model.
