ABSTRACT
BACKGROUND@#To investigate the diagnostic significance of percutaneous lung puncture for solid pulmonary nodules (diameter ≤15 mm).@*METHODS@#This study retrospectively included 20 patients with solid pulmonary nodules who underwent percutaneous puncture from January 2014 to December 2018, including 11 males and 9 females. The diameter of the lesion is between 0.5 cm-1.5 cm, excluding severe organ dysfunction, and patients with coagulopathy.@*RESULTS@#All 20 patients were successfully selected, and 19 patients were diagnosed with pathological diagnosis. Among them, 11 patients found malignant tumor cells, which were clearly malignant tumors of the lungs, 5 cases of chronic inflammation of the lungs, 2 cases of fibrous tissue hyperplasia, and 1 case of lung cartilage tissue, no tumor cells were found in 1 case. One patient with a small amount of pneumothorax after puncture and one patient with a small amount of pleural effusion on the puncturesite.@*CONCLUSIONS@#Percutaneous lung puncture has a high effectiveness and safety for the diagnosis of solid pulmonary nodules.
ABSTRACT
BACKGROUND@#Thoracoscopic safe and effective hemostasis is an important condition for rapid rehabilitation of thoracic surgery. Placing hemostatic materials during surgery is a commonly used method in lung cancer laparoscopic surgery. Among them, resorbable oxidized cellulose is a commonly used hemostatic material. This research aims to observe the hemostatic effect of resorbable oxidized cellulose in lung cancer surgery.@*METHODS@#A retrospective analysis of 42 patients with thoracoscopic lung cancer undergoing radical surgery in the Department of Thoracic Surgery, First Affiliated Hospital of Zhejiang University School of Medicine from July 1, 2018 to December 1, 2018, and intraoperative use of regenerative oxidized cellulose to stop bleeding The clinical and pathological data were selected and the perioperative indicators were selected as the outcome events for statistical analysis.@*RESULTS@#The mean operative time was (120.5±57.3) min. The mean intraoperative blood loss was (26.8±21.6) mL. The average postoperative drainage volume was (513.6±359.5) mL. The average postoperative chest tube indwelling time was (2.6±1.2) d.@*CONCLUSIONS@#The use of absorbable regenerated oxidized cellulose in the radical operation of thoracoscopic lung cancer has a good hemostasis effect, and is suitable for hemostasis of wounds after lymph node dissection.
ABSTRACT
Objective To evaluate the advantages of minimally invasive technique for treatment of progressive hemothorax.Methods The study enrolled 62 patients with progressive hemothorax treated by minimally invasive surgery between October 2009 and March 2012.According to the treatment methods,the patients were classified to thoracoscope group (n =47) and urethral catheter balloon blockage group (n =15).Postoperative drainage volume and recovery were detected in both groups.Results All patients in thoracoscope group were healed with the mean operation time of 54 minutes (range,30-120 minutes).Mean effusion removed within thoracic cavity was 1 260 ml (range,700-2 000 ml).Postoperative bedside chest radiography revealed good pulmonary reexpansion without effusion or pneumatosis within thoracic cavity.All patients in urethral catheter balloon blockage group were healed.Chest drainage within postoperative 3 hours was mean 260 ml of fresh blood (range,100-500 ml) and thereafter no more massive bloody fluid discharge occurred.Meanwhile,chest CT reexamination revealed no increase of chest effusion.Conclusion Minimally invasive technique in treatment of progressive hemothorax patients with moderate or less effusion provides accurate effect,minor trauma,rapid recovery,and few complications and hence deserves clinical application.
ABSTRACT
The periods of the medical students' clinical practice is an important transition from medical theory to medical practice.According to the medical interns' expectations,such as the clinical tutor' level,hardware of the department,daily medical process and our department' s experiences,we grope for much better teaching methods that can meet medical interns' expectations and evaluate the new teaching methods.The basic clinical skills of medical students and the teaching level of gastrointestinal surgery department have been effectively improved.
ABSTRACT
Protein degradation mediated by ubiquitin-proteasome pathway is involved in many biological processes.SCF complex is a sort of important E3 ubiquitin-ligase enzyme.Fbx4 protein is one of F-box protein family members,an important component of substrate-specific ScF Fbx4/αβ-crystallin ligase,and a subunit of SCF complex.Inactivation of Fbx4 protein or alteration of its expression level will influence activity of SCF Fbx4/αβ-crystallin ligase,thus will influence expression level of Cyclin D1.And Fbx4 protein is also an important regulatory factor for telomere maintenance.
ABSTRACT
To improve the medical students'comprehensive quality and clinical practice ability,we summarize personal and the department's experiences,enhance the students'education on their entering into clinic,accentuate basic skills of medical paperwork and endeavor to foster students'surgically logic thinking ability.
ABSTRACT
Thirty patients with rectal diseases, including 28 cases of rectal carcinoma and 2 cases of rectal villus adenoma, were reported. A11 the lesions were resected with anterior resection by the use of rectal stapling device.Satisfactory anastomoses were resulted in 27 cases. Two of the 3 failures were reanastomosed by the stapling device and another was revised by manual anastomosis. There were 3 cases of anastomotic complications,2 bleeding and 1 leakage.The indication and complications of colo-rectal anterior resection by the use of stapling device were discussed and we concluded that the stapling device had rather practical value in clinical use because it was easy to .practice, the complication rate was low and more anterior resections, could be done in diseases of middle and lower rectum
