Objective To study the efficacy of complement depletion with CVF in preventing a-cute rejection after heart allotransplantation in inbred strain rats. Methods Inbred male Lewis rats were used as recipients and Brown-Norway rats as donors, and the heterotopic heart transplantation model was established. The allografts were divided into 2 groups (n=8 in each group). After infusing low-dose CVF 20?g/kg to the CVF-treated group, cardiac allograft survival time was observed on 4 rats of each group. The remaining 4 rats in each group were killed respectively at day 1,3,5 and 6, the pathological grade for acute rejection, the complement activity in serum, the deposition of C3 on tissue, and the extent of infiltration by CD3+ T cells were compared. Results The mean survival time of heart allograft was (11. 69?0. 72) days and (6. 65?0. 35) days in CVF-treated group and control group respectively (P

Objective To eraluate the methods and results of endoscopic mucosal resections for colonic laterally spreading tumors with early malignant degeneration. Methods The pit pattern was studied with magnitying colonoscopy and mucosal staining technique for colonic laterally spreading tumors (LST) undergoing early earcinatous degeneration. They were removed with endoscopic mucosal resection techniques. A follow-up study was made. Results Eight patients suffering from early carcinoma on top of colonic laterally spreading tumors were followed-up. ① 75% of the lesions were situated in the rectum, sigmoid colon and decending colon. ② 75% of the lesions were larger than 30mm in diameter. ③ 75% of the lesions belonged to Ⅳpit pattern. ④ 62.5% of the lesions were Villous adenomas and 75% of the onalignant change involved the mucosa only. ⑤ All the lesions were completely removed by EMR, ⑥ No local residual lesion, recurrence or metastasis was discovered in all the patients after a mean follow-up period of 20.7 months. Conclusions Most of the early carcinomas originated from colonic LST involved the mucosa only. Endoscopic mucosal resection may be a curative method for the early cancer arising from colonic LST.

Objective To investigate the safety and effectiveness of endoscopical therapy for small grastric stromal tumor( d<2 cm) . Methods Clinical records of 80 patients dignosed as having small grastric stromal tumor by pathology and immunohistochemistry were retrospectively analyzed. Endoscopic or laparo?scopic or open surgery was performed, so patients were divided into endoscopic treatment group ( n=37) and surgical treatment group ( n=43) accordingly. Perioperative period data, effectiveness and follow?up data were analysed. Results Thirty?five cases( 94?6%) of endoscopic treatment group were successfully treated by endoscopic surgery. Intraoperative perforation occurred in 8 cases, among which 2 cases transferred for conventional operations.Pneumoperitoneum occurred in 2 cases (better after symptomatic treatment), while no serious infection or perioperative death occurred. There were no significant differences in the complete re?section rate[ 91?89% ( 34/37) VS 100?0%( 43/43) , P=0?095) , the incidence of postoperative complica?tions[5?71%(2/35)VS 2?33%(1/43),P=0?855)or the improvement of postoperative symptoms[93?10%( 27/29) VS 85?71% ( 30/35) , P=0?589] ,while statistically significant differences were found in operation time[(37?41±13?45)min VS(84?56±38?37)min, P=0?000], intraoperative blood loss[(5?65±5?88)ml VS(31?48 ±39?57)ml, P=0?000], postoperative feeding time[(2?47±0?61)d VS(3?26 ±1?27)d, P=0?001], postoperative hospital stay[(5?76 ±2?28)d VS(7?64±2?99)d,P=0?022],and medical expenses [(18 554?4±9 736?45)yuan VS(31 138?11±1 206?24)yuan, P=0?000].
