Objective To evaluate the effects of ultrasonic scalpel and traditional electrocautery on postoperative complications in axillary dissection for breast cancer treatment.Methods The clinical data of 92 breast cancer patients with axillary dissection were analyzed retrospectively.The surgical proce-dures were randomly chosen by patients,including 37 cases with ultrasonic scalpel and 55 cases with elec-trocautery.Both groups were compared in operation time,number of harvested lymph nodes,postoperative drainage in 24 h,seroma formation rate,and drain removal time.Results There were no significant differ-ences in operation time[(148.2 ±30.4)min vs(143.5 ±40.8)min],number of harvested lymph nodes (17 nodes vs 16 nodes),and drain removal time[(16.0 ±5.3)d vs(16.7 ±4.4)d]between ultrasonic scalpel group and electrocautery group(P >0.05 ).There were significant differences in postoperative drainage [(118.8 ±65.8)ml vs(159.2 ±71.3)ml]and seroma formation rate(8.1% vs 20%)between ultrasonic scalpel group and electrocautery group(P <0.01).Conclusion For breast cancer,ultrasonic scalpel is similar to electrocautery in axillary dissection,but it can reduce postoperative complications.

Objective To detect the change of CD47 on T-lymphocyte subsets marked by CD3 + CD4+ and CD3+ CD8+ in the acute graft versus host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and to explore its clinical significance.Methods The peripheral blood of 30 patients was collected before and every two weeks from hematopoietic reconstitution after allo-HSCT.The expression of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ was detected by flow cytometry,and the relationship between their expression and the occurrence of aGVHD was analyzed.Results The percentage of CD3+ CD4+-and CD3+ CD8+-marked T-lymphocyte subsets showed no statistically significant difference between aGVHD group and non-aGVHDgroup [(38.95 ± 6.18)％ vs.(37.38 ± 4.6)％,and (22.35 ± 3.32)％ vs.(20.34 ±4.56) ％,respectively] (P＞0.05).The expression levels of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ was obviously increased in aGVHD group when compared to before transplantation and non-aGVHD group after transplantation,and that had no changes in non-aGVHD group when compared to before conditioning regimen after transplantation.Mean fluorescence intensity of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ [(93.70 ± 14.88) and (70.09 ± 12.51)] in aGVHD group significantly increased as compared with non-aGVHD group [(71.27-± 11.32) and (53.93 ± 8.35)] (P＜0.05).There was no significant difference in the expression of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ before and after transplantation in non-aGVHD group (P＞0.05).Moreover the expression of CD47 on T-lymphocyte subsets marked by CD3 + CD4 + and CD3 + CD8 + changed correspondingly with the outcome of aGVHD in aGVHD group.Conclusion The change of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ andCD3+ CD8+ is valuable to monitor the aGVHD after allo-HSCT,which may provide a new means for the early detection of aGVHD.

Objectives:To assess bowel function and quality of life in patients with ulcerative colitis (UC)after ileal pouch anal anastomosis (IPAA).Methods:Clinical data of 37 UC patients after IPAA between 2014 and 2017 were retrospectively analyzed at Sir Run Run Shaw Hospital School of Medicine Zhejiang University. The IBDQ and Bowel Function questionnaire were used for analyzing correlation between clinical variables and quality of life or bowel function.Results:Laparoscopic operation was performed in 12 cases at stage 2 and 25 cases at stage 3. Postoperative defecation of stage 3 patients were better than that of stage 2 ( t=6.72, P<0.05). The number of daily defecation in age >45-year-old group was more than that in <45-year-old ( t=3.49, P<0.05), and the rate of evening stool seepage in the older group was higher than in the younger group( t=5.28, P<0.05). The total score of intestinal symptoms of IBDQ in patients of pouchitis was lower than that without pouchitis ( r=0.330, P<0.05). The total score in age >45 in terms of systemic symptoms ( r=0.349, P<0.05) and emotional function ( r=0.379, P<0.05) was higher than age <45. Conclusions:Outcomes of UC patients after IPAA are satisfactory, bowel function and quality of life is related with age, and stage of IPAA affect postoperative defecation.

Detection of pathogenic microorganisms has been a hot research field of microbiology.Conventional detection methods,such as isolation and culture, PCR technology, ELISA and genomic sequencing,are all time-consuming and com-plex.Because of the advantages of quick-testing, accuracy, safety and efficiency, spectroscopy has become a new non-inva-sive testing technology and has witnessed rapid development in pathogen detection and disease diagnosis.This article intro-duces three types of common spectroscopy technologies ( laser excitation fluorescence spectroscopy, infrared spectroscopy and Raman spectroscopy) , and also explains how they work in the detection of pathogenic microorganisms.

Objective:To conduct a scoping review of studies on the development and validation of web-based decision aids for fertility protection in cancer patients, so as to provide references for related studies.Methods:Using the Joanna Briggs Institute scoping review guideline as the methodological framework, PubMed, Web of Science, Embase, CINAHL, Cochrane Library, CNKI, Wanfang Database, VIP and China Biomedical Literature Database were searched.

Objective:To evaluate the characteristics, clinical management and clinical outcomes of type 2 intestinal failure (IF).Methods:A descriptive case-control study was carried out. The inclusion criteria were as follows: (1) the diagnosis of IF was performed according to the European Society for Parenteral and Enteral Nutrition (ESPEN) consensus statement. (2) using a requirement for parenteral nutrition (PN) of 28 days or more as surrogate marker. (3) a multidisciplinary team (MDT) included surgeons, nutritionist, pharmacist, stoma therapists, and critical care physicians. (4) complete laboratory data. Patients with type 1 and type 3 IF and those who do not cooperate with follow-up. All the data of 67 type II IF were collected from the database in Sir Run Run Shaw Hospital from Jan 2016 to Dec 2023. The pathophysiology, clinical management, and outcomes of type II IF were analyzed.Results:A total of 67 type II IF were included. The median age was 54 (15-83) with 43 males and 24 females. The body mass index was (17.5±3.8) kg/m 2, the incidence of malnutrition was 67.2% (45/67), the incidence of sarcopenia was 74.6% (50/67), the median number of previous surgeries was 2.0 (1-13), and the median duration time of PN was 2.1 (1-12) months. The underlying disease of type 2 IF included 36 Crohn`s disease, 2 ulcerative colitis, 3 radiation enteritis, 2 intestinal Behcet's disease, 4 mesenteric infarction, 1 aggressive fibromatosis, 5 abdominal cocoon syndrome, 5 gastrointestinal perforation, 1 hernia, 4 intestinal dysmotility, and 4 other reasons (gastrointestinal tumor, trauma, and non-Hodgkin's lymphoma). According to the pathophysiology of IF, there were 33 intestinal fistula, 12 intestinal dysmotility, 6 mechanical obstruction, 13 short bowel syndrome, and 3 extensive small bowel mucosal disease. After treatment with MDT, 67 patients with type 2 IF received nutritional support therapy for intestinal rehabilitation treatment, of which 36 patients recovered with oral diet or enteral nutrition, 31 patients underwent reconstructive surgery after intestinal rehabilitation treatment failure. The median duration time of reconstructive surgery was 2.7 (1-9) months. 24 patients recovered intestinal autonomy after surgery, with 7 deaths, including 6 deaths due to abdominal infections and 1 case of intestinal dysmotility with abiotrophy and liver failure. Conclusion:Standardized multidisciplinary treatment plays an important role in type II intestinal failure, and it promotes patients with intestinal failure regain enteral autonomy.
