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 6070° 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 Xray 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 (IL2, 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.
OBJECTIVE L-arginine is a semiessential dibasic amino acid for humans and animals. This paper aims to investigate the therapeutic effect of L-arginine supplementation on partial-thickness burned patients. METHODS A randomized controlled clinical trial was designed to evaluate the cellular immune function (T cell count, ratio of CD4/CD8, natural killer cell activity and IL-2 level) and protein metabolism (transferrin, prealbium and nitrogen balance) of patients in the experimental group which daily given 15 g arginine and the control group which daily given 25 g glycine. RESULTS The natural killer cell activity and IL-2 production in the experimental group were higher than that of the control group. The suppression of transferrin and prealbium was alleviated and the nitrogen balance was improved in the experimental group. CONCLUSION It suggests that exogenous arginine supplementation is beneficial for recovery of cellular immunity function and protein anabolism in partial-thickness burned patients.
ObjectiveTo investigate the pathogenesis, clinical manifestations, diagnosis and treatment of common variable immune deficiency (CVID).MethodsOne case of CVID with cellular immunodeficiency leading to bronchiectasis and liver cirrhosis was analyzed retrospectively. Relevant literatures were also searched through WanFang Database, China National Knowledge Infrastructure and PubMed, Ovid, Embase, Cochrane using the key words " common variable immunodeficiency”, " common variable hypogammaglobulinemia” in Chinese and English.ResultsA 52-year-old female patient, complained of cough, expectoration for 20 years, edema for 7 years and aggravated for 3 months with a history of recurrent respiratory infections was hospitalized in the West China Hospital of Sichuan University. The chest computed tomography revealed bronchiectasis, liver cirrhosis and portal hypertension. Laboratory tests showed remarkable hypogammaglobulinemia. The CD4+ T-cell count was below the normal range. Probable diagnosis of CVID was made based on clinical characteristics and laboratory tests. Immunoglobulin infusion with a dose of 20 g was given and the symptoms were relieved. About 288 case reports including 8 000 patients were searched. Most of them were reported individually. Conclusions CVID has a low morbidity and is rare in China. It is mostly caused by genetic factors. When there are recurrent infections in common areas of body, infections in rare areas or infections of conditioned pathogen, clinicians should be vigilant and give intervention as soon as possible. Family and genetic researches could be done when permitted.
Objective To investigate the effects of cimetidine on the red cell immune function and interleukin-2(IL-2) in rats with obstructive jaundice. Methods Sixty SD rats were divided into bile duct ligation(BDL) group, cimetidine therapy (BDLC) group and sham operation(SO) group respectively. The red cell immue function and serum IL-2 level were determined with the red cell yeast-rosttes test and radioimmunoassay respectively. Results The red blood cell C3b receptor rosette rate(RBC-C3bRR), the red blood cell immune complex rosette rate(RICR), the red blood cell C3b receptor rosette-forming excited rate(RFER) and serum IL-2 level were significantly lower in BDL group as compared with SO group, the red blood cell C3b receptor rosette-forming inhibitory rate(RFIR) in BDL group was higher than that of SO group. After 7 days’ cimetidine therapy RBCC3bRR, RICR, RFER and IL-2 became higher than those of BDL group, but RFIR was lower than that of BDL group. Conclusion Supplemental cimetidine can significantly enhance the impaired red cell immune function and IL-2 production in rats with obstructive jaundice.

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.
【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.
Objective To study the regulative effect of angelica sinensis on cellular immune function in perioperative patients with obstructive jaundice. Methods Fourteen patients with obstructive jaundice were injected with angelica before and after operation for 14 days. The activity of IL-2 and the expression of IL-2R in lymphocytes in peripheral blood were measured, respectively. Results The activity of IL-2 and the expression of IL-2R decreased significantly in patients with obstructive jaundice (P＜0.01). The activity of IL-2 and the expression of IL-2R in peripheral blood lymphocyte increased significantly before and after operations (after treatment using angelica) (P＜0.01), though there was a little decrease after operation but they were still higher than that befor using angelica.Conclusion It maybe useful to use angelica to improve the cellular immune function in patients with obstructive jaundice.
