  • CLINICAL OBSERVATION OF TRAUMATICALLYDAMAGED JOINT AFTER ITS REPAIR WITH TRANSPLANTATION OF ALLOGENIC JOINT

    Objective To evaluate the long-term function of the traumaticallydamaged joint after its repair with transplantation of a fresh or a frozen allogenic joint. Methods From March 1977 to September 1993, 13 patients (9 males, 4females; age, 17-55 years) with traumatically-damaged joints underwent transplantation of the fresh or the frozen allogenic joints. Five patients had 5 damagedmetacarpophalangeal joints, 6 patients had 9 damaged interphalangeal joints, and 2 patients had 2 damaged elbow joints. So, the traumatic damage involved 13 patients and 16 joints. All the metacarpophalangeal joints and the interphalangeal joints were injured by machines and the 2 elbow joints were injured by road accidents. The patients were randomly divided into 2 groups: Group A (n=7) andGroup B (n=6). The 7patients with 8 joints in Group A underwent transplantation of fresh allogenic joints; the 6 patients with 8 joints in Group B underwent transplantation of frozen allogenic joints. The allogenic joint transplants were performed in the period from immediately after the injuries to 6 months after the injuries. The motion ranges of the transplanted joints and the X-ray films were examined after operation, and the immunological examination was performed at 8 weeksafter operation. Results The time for synostosis was 5-8 months in Group A, but4-6 months in Group B. In Group A, at 2 years after operation the metacarpophalangeal flexion was 30-40° and the interphalangeal flexion was 20-30°; however,at 6 or 7 years after operation the interphalangeal flexion was only 10-20°. The patients undergoing the transplantation with fresh elbow joints had the elbowflexion of 60° and the elbow extension of 0°, and had the forearm pronation of 30°and the forearm supination of 30°. But in Group B, at 2 years after operation the metacarpophalangeal flexion was 6070° and the interphalangeal flexionwas 40-50°; at 6 or 7 years after operation the interphalangeal flexion was still 40-50°. However, the patients undergoing the transplantation with frozen elbow joints had the elbow flexion of 90° and the elbow extension of 0°, and hadthe forearm pronation of 45° and a forearm supination of 45°. The joint motion ranges, the Xray findings, and the immunological results in the patients undergoing the transplantation of the frozen allogenic joints were significantly better than those in the patients undergoing the transplantation of fresh allogenicjoints. There was a significant difference in the immunological examination between Group A and Group B (IL2, 21.64±3.99;CD4/CD8,3.88±0.82 vs.IL-2,16.63±3.11;CD4/CD8, 2.53±0.23, P<0.01). Conclusion Repairing the traumatically-damaged joints with frozen allogenic joints is a better method of regaining the contour, movement, and complex motion of the hands. 

  • Influence of Cardiopulmonary Bypass to the Cellular Immune Function o f T Lymphocyte

    Abstract: Objective To investigate the influence of cardiopul monary bypass(CPB) to the cellular immune function of T lymphocyte. Me th ods Among 500 patients operated from March 2006 to September 2006,30 patients with rheumatic heart disease were selected randomly as the CPB group, which would replace mitral valve; 30 patients with congenital patent ductus arte reriosus as the nonCPB group, which would ligate ductus arteriosus without CPB . The blood was sampled before operation, at the end of CPB or operation, and 24 hours after operation. After T lymphocyte was seperated, the quantum o f T lymphocyte, apoptosis of T lymphocyte, ability of T lymphocyte to kill tumou r cell were measured. Results The quantum of T lymphocyte i n CPB group at the end of CPB was decreased than that before operation (50.9% ±6.8% vs. 58.5%± 9.1%,Plt;0.05); apoptosis of T lymphocyte at the end of CPB and 24 hou rs after operation were increased than that before operation (6.5%±2.2% vs. 0. 9%±1.1%, 5.6%±1.8% vs. 0.9%±1.1%;Plt;0.01); ability to kill tumour cell b reakdown in CPB group at the end of CPB and 24 hours after operation was decrea sed than that before operation (30.4%±6.0% vs. 37.3%±8.6%, 29.0%±4.9% vs . 37 .3%±8.6%;Plt;0.05). Ability to kill tumour cell breakdown in CPB group was lower than that in nonCPB group at the end of CPB (30.4%±6.0% vs. 33.6%±5. 3%, Plt;0.05). Conclusion CPB can depress the cellular im mune function,which causes temporary immune depression to the body.

  • Function of RNA Editing Enzyme ADAR1 in Cellullar Immunologic Response in Mouse

    【Abstract】ObjectiveTo investigate the effect of RNA editing enzyme ADAR1 on the function of lymphocyte immune by transferring mouse lymphocytes with plasmid of sense siRNA and by suppressing the expression of ADAR1. MethodsThe cell strains of human hepatic cellular carcinoma (HCC) were frozen and thawed repeatedly to prepare for tumor soluble antigen. The isolated mouse lymphocytes, which were transferred with antisense siRNA plasmid of ADAR1 and were sensitized with soluble tumor antigen were used as the study group; those which were not transferred but were sensitized were used as the control group. The 3HTdR adulteration experiment was used to test the sensitivity of lymphocytes. The effect of ADAR1 on lymphocyte immunity was detected by lymphocytotoxicity tests. ResultsThe observation of the isolated lymphocytes implied that the growth cycle of lymphocyte was 10-14 days. The 3HTdR adulteration experiment showed the result was optimal. The number of HCCs decreased significantly for both of the groups compared with those in the blank holes, but the amplitude was much larger in the control group. The expression of ADAR1 in lymphocytes of the study group was significantly lower than that of the control group, which demonstrated that the RNA plasmid of ADAR1 suppressed the expression of ADAR1 in sensitized lymphocytes and the suppressing rate of the control group (87.47±4.62)% was significantly higher than that of study group (53.19±3.95)%. The function of lymphocytes killing targetcells in the study group was significantly inferior to that of control group (P<0.05). ConclusionRNA editing enzyme ADAR1 may play an important role in mouse cellullar immunologic response and it is possible to attenuate the cellimmune response by depressing the expression of ADAR1.

  • Effect of Bile Reinfusion on Immunologic Function of Erythrocyte in Patients with Obstructive Jaundice after External Drainage of Biliary Tract

    【Abstract】ObjectiveTo study the effect of bile reinfusion on immunologic function of erythrocyte in patients with obstructive jaundice after external drainage of biliary tract.MethodsPatients with obstructive jaundice who had received biliary tract external drainage were randomly divided into bile reinfusion group (n=24) and simple external drainage group (n=27). Patients without jaundice,who received cholecystectomy in the same period with the above ones,were selected randomly as control group(n=25). In external drainage groups patients’ bile was collected daily, and was filtered through gauze, and then, pumped back into the patients’ duodenum or jejunum after being heated to 38 ℃-40 ℃. The bile reinfusion could be started after the intestinal function recovered postoperatively. The changes of C3bRRT, ICRT, RFER and RFIR were observed before and after operation. The data were analysed through SPSS8.0.ResultsPreoperative C3bRRT and RFER levels in patients with obstructive jaundice were lower than those without jaundice significantly, and Preoperative ICRT and RFIR levels in patients with obstructive jaundice were higher than those without jaundice significantly. C3bRRT levels in bile reifusion group was higher obviously than those in simple drainage group (P<0.05) on the 14th postoperative day. ConclusionImmunologic function of erythrocyte in patients with obstructive jaundice is inhibited, and bile reinfusion after biliary tract external drainage can be helpful to the recovery of immunologic function of erythrocyte.

  • DYNAMIC STUDY ON PERIOPERATIVE CHANGES OF PROSTAGLADIN E2 AND CELLULAR IMMUNE FUNCTION IN PATIENTS WITH GASTRIC CANCER

    In order to investigate pre-and postoperative changes of prostagladin E2 (PGE2) and cellular immune function in patients with gastric cancer (GC), we measured T cell subsets, natural killer cell activity (NKCA) and PGE2 in peripheral blood (PB) of 31 GC patients and 30 controls with APAAP method, LDH release method and radioimmunoassay respectively. The results showed:① a significantly higher levels of PGE2, and a markedly lower levels of CD+4/CD+8 ratio in GC patients before surgery as compared with the controls. The PGE2 had a significant negtive coorelation with CD+4/CD+8 ratio and NKCA respectively.②PGE2 in PB of GC patients gradully declined to normal levels after surgery, moreover PGE2 in tumor tissue was markedly higher than that in normal tissue, implying that the tumor may be the major source of PGE2 in PB. Dynamic determination of PGE2 in PB would be great valuable in evaluation of cellular immune state, to evaluate the effect of surgery and prognosis of patients with gastric cancer.
