Objective:Exploring the diagnostic and therapeutic points of pectoralis minor muscle transection for the treatment of pectoralis minor syndrome, as well as the differences between pectoralis minor syndrome and thoracic outlet syndrome.Methods:A retrospective summary and analysis were conducted on the clinical data, surgical methods, and prognosis of patients with pectoralis minor syndrome who underwent thoracic and cardiovascular surgery at the Second Affiliated Hospital of Southwest Medical University from January 2012 to December 2022. The literature was reviewed, and the clinical data, surgical methods, and prognosis of thoracic outlet syndrome during the same period were combined to analyze the differences between pectoralis minor syndrome and thoracic outlet syndrome.Results:All patients underwent surgical resection of the pectoralis minor muscle, with significant pain relief, disappearance of clinical symptoms, no surgical complications, and a good prognosis.Conclusion:Pectoral muscle syndrome is a disease independent of thoracic outlet syndrome, with a high rate of missed diagnosis and misdiagnosis. Comprehensive preoperative pain localization and closed treatment, clear diagnosis, and cutting of the pectoralis minor muscle are effective methods for treating this disease.

Objective To investigate the effect of flurbiprofen administration time on inflammatory factors in patients with acute suppurative appendicitis after laparoscopic resection. Methods 60 patients with acute suppurative appendicitis resection treated in our hospital from January 2015 to March 2017 were divided into two groups according to the different administration time. The control group received flurbiprofen at the time of operation, and the observation group received flurbiprofen before operation induction; The changes of the indexes of operation and inflammatory factors before and after the operation were compared between the two groups. Results There were no significant differences between the two groups in each operation index; The level of inflammatory factors in the observation group was better than that in the control group 24 hours after the operation, the difference was statistically significant (P<0.05). Conclusion The effect of flurbiprofen is significant before the induction of anesthesia, and the control effect of inflammatory factors is good after the operation, and the time will not affect the postoperative analgesia.

Objeetive:To study the expression of cell adhesion molecules on the lymphatic endothelial cells In the rectum cancer and peritumoral lymph nodes as well as their relationship with the diffusion of cancer cellS. Methods: In this Study the immunhistochemistry method was employed to observe the expression of CEA, ICAM-1 and CD31 on rectum cancer lymphatic endo-thelial cells. Results :The results demonstrated that CEA and lCAM-1 were highly expressed on the lynphatio endothelial cells in the peritumoral rectum tissues and lymph nodes. It was, howev-er,negative in normal lymphatic endothelial cells. CD31 was expressed on both lymphatic endothe-Ilal cells in the periturmral rectum tissues and lymph nodes and vessel endothelial cells of the normal human. Conelusion: The study suggests that there are relationships between the dis-semination of cancer cells and excession of CEA, lCAM-1 and CD31 in lymphatic endothelial cells.The CAE and ICAM-1 seem to induce stable adhesion between oancer cells and endothelial cells.
