Objective To investigate the role of biopsy kidney allograft in the early diagnosis and differential diagnosis of acute and chronic rejection and other diseases involving renal allograft,and to determine the optimal time for early biopsy in chronic allograft rejection.Methods Non-random biopsy of renal allograft was performed in 44 kidney transplant recipients with the clinical manifestation of diagnosis-unconfirmed allograft diseases,in the presence increased in serum creatinine,microalbuminuria or/and proteinuria,glomerular hematuria and so on.Another 6 kidney transplant recipients received routine allograft biopsy 1 month after operation.Pathological evaluation was performed in all sections according to Banff 97 classification and based on clinical data.Results Chronic allograft rejection was discovered in the renal allograft specimens of 31.3%,76.5% and 88.2% recipients,respectively,in the 1st year,the 2nd to 3rd year and over 3 years after operation,and most of them showed no obvious clinical manifestation.A part of recipients with clinical diagnosis of acute rejection also showed pathological manifestations of chronic rejection and/or glomerulonephritis and chronic cyclosporine nephropathy.A part of recipients with clinical diagnosis of chronic rejection showed pathological manifestations of acute rejection and/or glomerulonephritis and chronic cyclosporine nephropathy.Pathological features of acute or chronic rejection,glomerulonephritis and chronic cyclosporine nephropathy were observed respectively in recipients with disorders of kidney allograft with unknown diagnosis.No obvious clinical symptoms were observed in nearly half of the patients with pathological diagnosis of glomerulonephritis.Good therapeutic effect was obtained in these recipients who were correctly treated on the basis of definite pathological diagnosis.Conclusions It is indicated that optimal time for early diagnosis in chronic renal allograft rejection might be the 2nd and 3rd year after transplantation,and routine biopsy should be performed in this period.It is suggested that biopsy of renal allograft is of importance value for rectification of clinical diagnosis and for recipients with clinically undefined renal allograft diseases.It is also indicated that there might be coexistence of acute,chronic rejection and/or glomerulonephritis and chronic cyclosporine nephropathy.

Literatures on arrhythmia induced by acute organophosphorous pesticide poisoning published in domestic journals from 1979 to 2010 were searched. Total 3468 cases of acute organophosphorous poisoning were collected and analyzed. The average abnormal ECC rate was (53 ±15)%(35. 4% -68. 4% ) in acute organophosphorous poisoning, the most common ECG abnormalities were ST-T segment changes (26. 5% ) and sinus tachycardia (16. 6% ). The rate and severity of ECG abnormalities were increased with the severity of organophosphorous poisoning(x2 = 33. 253,P < 0. 01). The most common causes of death in acute organophosphorous poisoning were ventricular tachycardia and ventricular fibrillation (26.2%).

Otransplantation is a new subject which is developed so rapid that usually over the development of medical ethics.The shortage of organ supplement made organ transplantation face the challenge of medical ethics.Live organ donation has become a focal point of medical ethics in organ transplantation.It is necessary to eliminate all kinds of human organ commercialization and illegal transaction.We need pay more attention in the medical ethics issue about organ transplant,especially about live organ donation.Here is about the survey of medical ethics on live organ donation in People's Liberation Army No.181 Hospital.

Objective:In order to study the effect of forkhead box c2 (Foxc2) on the development of skeleton and aorta Methods:Rat monoclonal anti mouse Foxc2 antibody was prepared by using recombinant fusion protein GST Foxc2, and used it to detect the expression of Foxc2 protein in C2C12 myoblasts and embryo of mouse Results:The titer of rat anti mouse Foxc2 antibody was 1: 5 000 This monoclonal antibody can specifically recognized Foxc2 protein producing in mouse L cells and human bladder carcinoma HTB9 cells transfected with CX Foxc2 plasmid Endogenous Foxc2 protein was detected in the mouse myoblast C2C12 cells and increased significantly in C2C12 cells after treatment with bone morphogenetic protein 2(BMP 2) Endogenous Foxc2 protein level was lowered markedly by transfecting C2C12 cells with antisense Foxc2 sequence Foxc2 protein in 11 5 dpc embryo was localized in the developing selerotome and mesenchymal tissue around the aorta Conclusion:Rat anti mouse Foxc2 monoclonal antibody was successfully prepared by using recombinant fusion protein GST Foxc2 The BMP 2 induced Foxc2 protein may play an important role in regulating the osteoblastic differentiation of C2C12 myoblasts and in the formation of axial skeleton and aortic arch

Objective To detect the prevalence of hyperuricemia and its relationship to chronic kidney disease(CKD) in the residents of Guangxi, and to discuss the risk factors for the hyperuricemia associated renal damage. Methods The residents aged 18-75 years old(n=6 273) in Xiangshan community,Guilin, were screened by means of cross-sectional study. Blood pressure was measured at 8:00-9:00.Fasting blood and urine samples were collected to determine blood glucose, lipid, insulin, creatinine, and urine albumin. Results The prevalence of hyperuricemia in the community residents was 23.5% in all cohort, being significantly higher in male residents than in female(28.4% vs 19.7%,P＜0.01). The prevalence of CKD was 21.6% in all cohort, and was 24.9% in males and 19.0% in females(P＜0.01). The prevalence of CKD was 30.4% and 18.9% respectively in residents with and without hyperuricemia(P＜0.01).The prevalence of CKD in males with hyperuricemia(34.3%) was significantly higher than in males without hyperuricemia(21.2%) and females with hyperuricemia(25.9%, all P＜0.01). CKD was only positively related to low-density lipoprotein cholesterol, blood glucose, and systolic blood pressure shown by logistic regression analysis. Conclusions The prevalence of hyperuricemia markedly increases in the urban residents, which contribute to the raised prevalence of CKD. Slightly elevated blood uric acid level is associated with raised prevalence of CKD.

Objective To investigate the risk factors of insulin resistance(IR)and its relationship with metabolic syndrome in patients after lenal transplantation.Methods 133 renal transplant redpients who had not undergone acute rejection,calcinurine intoxication and severe infection,and had normal renal function and no proteinuria at the 6th month post-transplantation,were involved in the study.They had a history of chronic glomerulonephritis as the primary disease of ESRF but rio diabetes mellitus.108 recipients(CsA group)were treated with CsA,mycophenolate mofetil(MMF)and prednisone after transplantation,19 recipients(Tac group)with tacrolimns(Tac),MMF and prednimne,and 6 recipients with Simlimus,respectively.One year later,blood and urine biochemical tests and physical examinations were performed on the recipients,and HOMA calculated.200 cormnunity residents were randomly selected as controls.Results The incidence of MS in the recipients was 33.1%,significantly higher than controls(15.0%).There was no significant difference in the incidence of obesity and overweight between recipients(29.3%)and controls(37.5%).In recipients with obesity or overweight,the insulin-resistance level and urine albumin level,and the incidence of MS weree significantly higher than those without obesity or overweight.The insulin-resistance level in Tac-treated recipients was markedly higher than CsA-treated recipients,and there was a positive correlation between the blood concentration of Tac and insulin-resistance levd.Microalbuminufia-positive recipients had higher insulin-resistance levels.Metabolic syndrome-complicating recipients had higher insulin-resistance levels than those without metabolic synawme,and higher insulinresistance levels existed in recipients with hypertriglyceridemia or hyperchcllesterolemia,hypertension.Conclusion Obesity or overweight,Tac(especially when blood concentration was higher)were risk factors resulting in imulin-resistanee in kidney transplant recipients.It is suggested that insulin-resistance might be involved in the pathogenesis of metabolic syndrome including hypertrglyceridmaia,hypercbolestemlemia and hypertenion.

BACKGROUND: A large number of researches have confirmed that hypertension, vascular nephrosclerosis and chronic systemic inflammatorome were the importance factors of chronic allograft dysfunction. Hyperuricemia is associated with primary hypertension and vascular nephrosclerosis, and can result in chronic systemic inflammatorome, but it was uncertain whether post-transplantation hyperuricemia and its lesion influence the long term graft function. OBJECTIVE: To investigate the prevalence of hyperuricemia in renal transplant recipients (RTRs) before and after transplantation and the influence of hyperuricemia on long term graft function. METHODS: A total of 216 renal transplant recipients [146 males with the mean age of (40.98±11.09) years and 70 females with mean age of (40.01±11.62) years]with normal renal function after transplantation were selected from PLA Center of Kidney Transplantation and Dialysis, the 181 Hospital of Chinese PLA. In order to compare the influence of different hyperuricemia status on the long term graft function, the patients were divided into 4 groups according their pre-transplant baseline and post-transplant serum uric acid (SUA) levels, SUA normal group, pre-transplant high SUA group, post-transplant high SUA group and both pre-transplant and post-transplant high SUA group. The patients were also divided into 3 groups according to their post-transplantation SUA level to study the influence of SUA on the long term graft function, normal SUA group, hyperuricemia (SUA < 500 μmol/L) group and hyperuricemia (SUA > 500 μmol/L) group. Effects of hyperuricemia and SUA levels pre-and post-transplantation on long term graft function were observed. RESULTS AND CONCLUSION: Hyperuricemia existed in 34.2% male RTRs and 37.7% females before transplantation, while it existed in 36.2% male RTRs and 42.4% females at the first month post-transplantation when they had normal Scr levels. The incidence rate of post-transplant hyperuricemia in female RTRs was significantly higher than male RTRs (P < 0.05). The average post-transplantation SUA levels in both male and female RTRs were significantly higher than those before transplantation (P < 0.01). At follow-up end, the pre-transplantation SUA levels did not significantly influence on the long term graft function (P > 0.05), meanwhile the RTRs with continuous post-transplant hyperuricimia had poorer long term graft function than those with normal post-transplantation SUA levels. It is indicated that hyperuricemia is more common in post-transplantation recipients, especially in female RTRs, when compared to pre-transplantation, and post-transplantation hyperuricemia often existed in renal transplant recipients with normal graft function. Furthermore it is suggested that post-transplantation hyperuricimia, but not pre-transpiantation hyperuricemia, could also act as a factor inducing chronic renal allograft dysfunction.

Objective To evaluate the short-term effects of total knee arthroplasty ( TKA) , and to detect the causes and prevention of major complications. Methods It was a retrospective study since January 2010 to December 2013. There were 63 patients with 70 knees re-ceived primary TKA. KSS knee scores, HSS knee scores, and range of motion ( ROM) before the operation and during the follow-up were as-sessed and analysed. Results According to the results of follow-up and the X-ray observation, the anteroposterior radiographs showed that the artificial prosthesis were placed well and the joint gap were balanced;the lateral radiographs showed that the artificial joint prosthesis we-rer of appropriate size, good tilt angle, and good package effect. There were two cases developed peroneal nerve palsy and they gradually re-stored in 4 to 6 months after surgery. 5 cases were of poor postoperative ROM (0~60 ± 10)°. Strong analgesic medication-assisted release were conducted in 2 to 3 weeks after surgery. 1 case had patellar pain and resorted by arthroscopic lateral ligament of patellar releasing sur-gery. During the follow-up period, TKA significantly improved HSS and KSS scores compared to preoperative scores. ROM was increased from (78. 3 ± 18. 6)° preoperatively to (109. 2 ± 19. 9)° postoperative (P<0. 01). Conclusion TKA was effective to release knee pain, improve ROM and reduce the incidence of postoperative complications.

Objective The aim of the study was to observe the features of nail fold microcirculation in systemic sclerosis (SSc) patients and to compare these findings in SSc patients with patients with other connective tissue diseases.Methods Forty patients with SSc and thirty-seven patients with other connective tissue diseases were included in the study and all the patients reported symptoms of Raynaud's phenomenon in the hands were also included.Nail fold capillaroscopy (NFC) was performed and the abnormality of nail fold microcirculation between the two groups were compared.The relations between nail fold capillaroscopic findings and clinicolaboratory parameters in SSc patients were analyzed.Statistical analysis were carried out by t-test and Chi-square.Results The loss of capillaries and dilated and giant capillaries and hemorrhage as well as neoangiogenesis were hallmarks of the scleroderma capillary findings,which could be detected by nail fold capillaroscopy.The abnormalities of nail fold microcirculation in SSc patients were more severe and more specific than those in other connective tissue disease patients.The total scores of nail fold capillaroscopy test were obviously higher in SSc patients with lung or esophagus involvement than those patients without these organ involvement,meanwhile,the total scores of nail fold capillaroscopic findiugs were elevated in SSc patients with anti-Scl70 antibody than those with negative group.Conclusion The nail fold capillaries of patients with SSc have specific abnormalities,and nail fold capill-aroscopy could distinguish between SSc and other connective tissue diseases,therefore it could be used as a promising tool for early detection of patients who may have the potential to develop scleroderma and it is also helpful in assessing disease severity.
