China is one of the countries with the highest incidence of esophageal cancer, which is still increasing year by year in recent years. Surgical treatment is the first choice for early and middle esophageal cancer. Surgeons have been exploring how to remove the tumor as completely as possible and reduce the trauma as far as possible. In recent years, with the rapid development of minimally invasive surgery and endoscopic technology, minimally invasive esophagectomy(MIE)has led the trend of radical surgery for esophageal cancer. At present, the mainstream minimally invasive surgery is thoracoscopic thoracoscopic(VATS)resection of esophageal cancer, which requires thoracotomy and anesthesia, resulting in large surgical trauma and more complications of postoperative circulatory respiratory system. Mediastinose-assisted esophagectomy(MAE), which eliminates a thoracotomy, is also an important part of MIE. Overseas MAE application started early, but the domestic development is relatively slow. This article summarizes the experience of different MAE surgical methods in China, and provides the basis for its promotion in China.

Objective To evaluate endovascular treatment of Budd-Chiari syndrome(BCS)with occlusion of hepatic veins.Methods Retrospective analysis on the clinical materials of 32 BCS cases with occlusion of hepatic veins was made.Four cases received inferior vena cava(IVC)angioplasty or stent implant and splenorenal shunt;Transfemoral vein or transjugular hepatic vein angioplasty was performed in 10 cases,and percutaneous transhepatic recanalization combined with transjugular and/or transfemoral vein angioplasty of hepatic veins was performed in 16 cases,respectively.Two cases failed therapy attempt.Results A failure to find the main hepatic vein in percutaneous transhepatic venography lead to the abandent of therapy in 2 cases.Hepatic vein angioplasty and IVC angioplasty was successful in the other 30 cases.The pressure of hepatic vein decreased from(43±8)cm H_2O to(16±4)cm H_2O(t=21.23,P<0.01).The symptoms were obviously relieved,ascites disappeared,abdominal distension palliated,chest and abdominal wall varicose veins collapsed one week after endovascular treatment.During perioperative procedure,2 cases with liver puncture bleeding were cured by laparotomy.The follow-up duration was 5 months to 65 months and mean(26.0±2.0)months.There was no stent migration and hepatic vein restenosis and occlusion.Chest and abdominal wall varicose veins disappeared and esophagus phlebeurysma were ameliorated as shown by esophageal barium series.There were no pulmonary embolism and death.Conclusions The procedure of endovascular treatment of BCS with occlusion of hepatic veins is simple,mini-traumatic and effective.

AIM: To investigate the effect of Shexiang Baoxin Pill(SXBXP) on endothelial in stable angina pectoris patients and its underlying mechanisms. METHODS: Sixty-eight stable angina pectoris patients were randomly divided into two groups,the conventional group(34cases),SXBXP treatment group(34cases).The conventional group was treated with standard treatment,and SXBXP group was treated with standard treatment and SXBXP.FMD,NO,ET,TXB_2,6-Keto-PGF-1a were determined before and after three months treatment. RESULTS: FMD,NO,6-Keto-PGF-1a of SXBXP group were (9.35%?0.78%)、(77.25?6.36)?mmol/L、(93.87?(10.28))?/(ng/L) after treatment,ET、TXB_2 were(81.15?5.43) pg/mL、(43.02?4.19)?/(ng/L).There were significant improvement as compared with in SXBXP group before treatment and in conventional group after treatment(P
