Objective Based on investigating the results of brachial plexus nerve transfer to repair the femoral nerve in rats, C7 nerve root transfer to femoral nerve autograft to reconstruct the function of quadriceps femoris of paraplegia was designed and evaluated clinically. Methods 16 SD rats were randomized into 2 groups. Group A: the radial nerve of the left side was severed, and the proximal end of the radial nerve was transferred to the femoral nerve of the lower limb on the same side through the vascularized sciatic nerve bridging in one stage; Group B: the radial nerve anastomosed with the bridging nerve at first, then 3 months later the femoral nerve was sectioned, and the distal end of which anastomosed with the bridging nerve. Electrophysiology and histology including amplitude of compound action muscle potential, muscle wet weight, cross section areas were used to evaluate the effects at sixth month after operation. Furthermore, two patients with paraplegia were treated by the C7 nerve root transfer to reconstruct the function of quadriceps femoris. The C7 was sectioned at the distal of nerve root , and proximal end was used for motor nerve, the vascularized tibial nerve sectioned at the middle of the crus and dissected to the rump along the posterior of lower limb was reversed to the ipsilateral cervical incision through the tunnel and used for bridging nerve to anastomose with the proximal end of C7. When the nerve fiber regenerated into the hip through bridging nerve, the femoral nerve was sectioned and distal end anastomosed with bridging nerve. Results There was no significant difference between the two groups in the results of nerve regeneration and amplitude of compound action muscle potential, but group B was superior to the group A in muscle net weight and section area of muscle fiber. One case suffered paraplegia had already been repaired the double side femoral nerve by the method, after 41 months follow up, the muscle power of quadriceps was 4 grade on the right side and 3 grade on the left. The other was followed up for 24 months, the muscle power of quadriceps was 2 grade on both sides. Conclusion C7 nerve transfer to repair the femoral nerve through the vascularized tibial nerve bridging in two stages could reconstruct the movement and sensation function of lower limb of paraplegia.

Objective To evaluate the method of endoscopic band ligation in resecting upper gastrointestinal leiomyoma . Methods We selected 59 patients with 64 small upper gastrointestinal tract leiomyo-mas by endoscopy , EUS and EUS guided fine needle aspiration. Of the 64 leiomyomas, their distribution were in esophagus 50, stomach 12 and duodenum 2. When the endoscope with transparent cap was introduced to reach the lesion, it was sucked into the cap, then released the band to ligate it. Two weeks after operation, endoscopic monitoring of the lesion was performed weekly until the complete healing of the wound. Results In the 64 lesions, 50 esophageal and 2 duodenal leiomyomas were thoroughly resected and the mean concrescence time is 3. 1 weeks and 4. 5 weeks respectively. Nine of 12 gastric leiomyomas were resected thoroughly and the other 3 were partially ligated and resulted in incomplete excision with the mean concrescence time of 4. 5weeks. No perforation occurred. Conclusions Endoscopic band ligation is an ideal method in resecting the small upper gastrointestinal leiomyomas.

The interaction between the antibody and the corresponding target molecule determines the characteristics of immunoassay. In this study, a single chain variable fragment antibody (scFv4C7) derived from the hybridoma strain 4C7 were prepared via genetic engineering technique. The recognition properties of scFv4 C7 was determined and compared to those of the parent monoclonal antibody by indirect competitive enzyme-linked immunosorbent assay(ic-ELISA). Three dimensional structure of the scFv4C7 was presented by Swiss-Model, and sulfathiazole ( STZ) was docked to the scFv4C7 model to obtain the structure of the binding complex. The results from the ic-ELISA showed that the binding properties of scFv4C7 were comparable with the parent monoclonal antibody and STZ was almost completely buried in a deep binding pocket formed by the heavy chain and light chain of the antibody. The interaction between STZ and scFv4C7 was more closely related to the heavy chain and the complementarity-determining region ( CDR ) H3 loop played more important role than other CDR loops. The study preliminary provided the necessary structural information for the preparation of antibody with broader specificity and higher affinity.

Objective To report the cloning, expression and identification of the tumor-associated antigen G250/MN/CA Ⅸ. Methods The total RNA was extracted from renal cell carcinoma tissue samples from 54 male patients. Gene fragments encoding G250 was obtained by RT-PCR,and was cloned into prokaryotic expression vector pET22b(+) and expressed in E.coli BL21(DE3);and the results were examined by SDS-PAGE gel electrophoresis. The recombinant protein was studied by Western blot test. Results DNA sequence analysis showed that the obtained sequence was the same as that showed in GenBank.Gene of G250 was expressed in E.coli BL21 successfully. Western blot analysis showed that the recombinant protein could be specially recognized by monoclonal antibody. It had better antigenicity and specificity. Conclusions This study provides experimental basis for the purification of G250/MN/CA Ⅸ protein and the further study of G250/MN/CA Ⅸ function and preparation of antibody.

Objective It is difficult to differentiate tumors in upper GI muscularis proporia, such as GI stromal tumors (GISTs) , leiomyomas and schwannomas. We performed EUS guided fine needle aspirations (FNA) and immunohistochemical evaluation of these tumors in upper GI muscularis proporia. Methods We selected 35 Patients with lesions in upper GI muscularis proporia by EGD and EUS. We assessed the shape , size, and position of the lesions and the status of metastasis. After excluding blood vessel between the lesions and the fine needle, EUS FNA were carried out and immunohistochemical staining for CD-117 (c-kit) , CD34 and smooth muscle actin ( SMA) was performed. Results All patients were performed EUS FNA and enough specimens were obtained in 31 patients. The other 4 failed, although we tried it for several times. Among the 31 patients, Cytology and immunohistochemisty demonstrated 21 GISTs and 10 leiomyomas. All the results were evaluated by surgery. The sensitivity is 88. 6% , and the speciality is 100%. No complication occurred. Conclusion EUS-guided FNA and immunohistochemical evaluation is an accurate method for diferential diagnosis of tumors in upper GI muscularis propria.
