Objective To detect serum concentration of folate receptor alpha and to investigate its significance in the clinical application of patients with endometrial carcinoma. Methods Thirty-seven patients with endometrial carcinoma, 33 patients with endometrial hyperplasia and 10 healthy women were enrolled in this study. Sera were used to detect the the folate receptor alpha using an Enzyme-linked Immunosorbent Assay (ELISA) technique.The expression level of serum folate receptor alpha in different groups was analyzed. The correlation between the expression level of serum folate receptor alpha and age of patients, menopause, tumor morphology, myometrial invasion and clinical stage was was also analyzed in patients with endometrial carcinoma. Results Level of folate receptor alpha was successfully detected in serum of healthy women and patients with endometrial diseases. Level of folate receptor alpha in patients with endometrial carcinoma was much higher than that in patients with endometrial hyperplasia. Level of folate receptor alpha in patients with endometrial hyperplasia was also higher than that in the healthy controls, with significant difference (P < 0.05). In the endometrial carcinoma group,the levle of folate receptor alpha in serum was correlated with the clinical stage and myometrial invasion (P < 0.05), however, Level of folate receptor alpha was not correlated with the age of patients, menopause andtumor morphology(P > 0.05). Conclusion The Serum level of folate receptor alpha can be detected, and its expression will contribute to the diagnosis, treatment and predicting the prognosis of patients with endometrial carcinoma.

Objective To investigate and compare the effect of cyclosporine A (CsA) vs. tacrolimus (TAC)-based immunosuppressive regimen on chronic allograft nephropathy. Methods Ninety-six patients who received a cadeveric kidney transplantation in our unit during Jan. 1995 to Jan. 2004 more than 12 months prior to study enrollment and who were being treated with CsA-based immunosuppressive treatment were included. All patients received allograft biopsy and were diagnosed as CAN. Patients were differentiated according to following regimen. Patients were either converted to tacrolimus (TAC group, n=58) or remained on their initial CsA-based immunosuppression (CsA group, n=39). The clinical data at study entry and after 3, 6 and 12 months including serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), blood urea nitrogen (BUN), creatinine (SCr), albumin were recorded during a follow-up of over 12 months. Results Though TC, TG and LDL levels remained unchanged in CsA group, while statistically reduced in TAC group respectively ( 6.60? 1.34 mmol/L vs. 5.20? 0.75 mmol/L, 3.00? 1.40 mmol/L vs. 1.90? 0.86 mmol/L, and 3.70? 0.93 mmol/L vs. 3.00? 0.72 mmol/L, P

Six five renal graft biopsies were performed routinely in 36 renal transplantation patients with normal renal function 1 and 3 months after transplantation. All the patients were given the immunosuppressive regimen of cyclosporine A (CsA), prednisone (Pred), azathioprine (Aza) and Tripterygium Wilfordii Hook (TW). The histological diagnosis of allograft biopsy was made according to the Banff schema. In 18 45% of the biopsies (12/65), early subclinical rejection or borderline changes were found. There was a significant difference for different dosages of TW, but no difference for the dosages of CsA, Pred and Aza intravenous between patients with pathological changes and those without. The patients with early subclinical rejection or borderline changes, methylpredisolone was given in bolus, followed by the adjustment of immunosuppressive regimens. With this treatment, there was no difference in 5 year survival rate between them and those with normal renal allograft biopsy findings. The routine allograft biopsy helps discover early subclinical rejection and borderline changes in patients with renal transplantation, and beneficial for adjustment of immunosuppressive therapy.

Objective Little research has been done on the risk factor analysis of BK virus(BKV) infection in renal transplant recipients in Chinese population.The article aimed to investigate BKV infection and analyze its risk factors in renal transplant recipients in China.Methods Renal transplant recipients who had received the detection of BKV DNA in urine and blood samples in Nanjing General Hospital from June 2015 to July 2016 were selected, while the patients with uremia hemodialysis and healthy living donors were included as control group.According to the detection results of BKV DNA in urine and blood samples, renal transplant recipients were divided into BKV DNA positive group(n=89, positive urine or blood and urine BKV DNA) and BKV DNA negative group(n=359, negative blood and urine BKV DNA).Analysis was made on BKV infection in renal transplant recipients in order to investigate the effects of factors including clinical condition, postoperative complications and immunosuppressive regimen on BKV infection.Results The positive rate of BKV DNA in urine samples of renal transplant recipients was 19.9%, which was higher than those of patients with dialysis and healthy living donors(6.3% and 4.2% respectively, P<0.001).Multivariate logistic regression analysis showed BKV infection was associated with pulmonary infection(OR[95%CI], 3.468[1.227-9.802];P=0.019) , acute rejection (OR[95%CI], 2.645[1.142-6.127];P=0.023), and FK506 (OR[95%CI], 2.408[1.104-5.254];P=0.027).Conclusion The incidence of BKV infection in renal transplant recipients increases significantly.Pulmonary infection, acute rejection and FK506-based immunosuppressive regimen are risk factors leading to BKV infection.

Objective BK virus-associated nephropathy ( BKVAN) after kidney transplantation is a key factor that influence the prognosis of transplant kidney .To our knowledge , it is believed to be associated with immune suppression .We observed the cura-tive effect and influencing factorsof anti-rejection scheme that Leflunomide was administered instead of Mycophenolate Mofetil ( MMF) on transplant kidney BKVAN .. Methods This study included 15 kidney transplant recipients with pathologically confirmed BKVAN in Nanjing General Hospital of Nanjing Military Region form March 2007 to March 2013 .Leflunomide was administered instead of Myco-phenolate Mofetil ( MMF) .Serum creatinine level , renal allograft loss rate and side effects of leflunomide were monitored after medica-tion switch.The patients were divided into two groups , which were renal allograft loss group and renal allograft survival group , for fur-ther analyses . The differences between each groups in clinical characteristics as well as histochemical features of the transplanted kidneys were analyzed to determine the cause of renal allograft loss in patients with BKVAN . Results Six patients experienced renal al-lograft loss after switching to leflunomide and needed hemodialysis , and 9 patients had stable renal allograft function , renal allograft loss rate was 40.0%.Hyperuricemia occurred in 8 patients in the period before the medication switch and in 5 patients after the switch;a decrease in blood white cell orplateletcount was found in 2 patients during both periods;an increase in Alanine aminotransferase ( ALT) level occurred in one patient after the medication switch .There were no statistically significant differences in any of the above parame-ters before and after the medication switch.Compared to allograft survival group, serum creatinine level[(1.80 ±0.53)mg/dL vs (2.74 ±0.58)mg/dL, P=0.007], the number of B lymphocytes [(206.44 ±144.96) vs (439.67 ±267.77), P=0.047] and CD68[(588.44 ±271.80) vs (944.67 ±259.32), P=0.025] in renal allograft tissue were significantly higherin the allograft loss group. ConclusionLeflunomide is a safe and effective medication for BKVAN .Patients with significantly increased serum creatinine level might have a poorer prognosis .Significantly increased B lymphocytes and CD 68 cells in renal allograft tissue might indicate a poor prognosis.

Objective Sirolimus ( SRL) is a potent immunosuppressive drug used to prevent acute allograft rejection after re-nal transplantation.Nevertheless, the occurrence of proteinuria has recently been recognized among patients treated with SRL-based therapy.The aim of this study was to investigate the therapeutic effect of tripterygium wilfordii hook F ( T II) on proteinuria caused by SRL in renal transplant recipients who were treated by trilogy immunosuppressive therapy of sirolimus combined with mycophenolate and hormone. Methods 52 recipients were divided into 2 groups randomly:TⅡgroup (n=27) and valsartan group (n=25).The TⅡgroup was administered 1 mg/kg/d, and the valsartan group 80-160 mg/d for consecutive 12 months.Based on primary trilogy immu-nosuppressive therapy of sirolimus combined with mycophenolate and hormone, the dosage of sirolimus was adjusted according to the target concentration 6-10 ng/ml( ELASA approach) and mycophenolate was administered 750 mg twice per day, adjusting dosage ac-cording to the mycophenolate AUC 0-12 level(35-45 mg· h/L).The evaluation of therapeutic effect includes: complete remission, proteinuria decreased by>50%; partial remission, proteinuria decreased by 20% to 50%; ineffective, proteinuria decreased by<20%. Results During the 12 month follow-up, the total effective rates in the TⅡgroup and the valsartan group were 95.2%and 86.7%respectively, in which the TⅡ group decreased more significantly (P<0.01).The total cholesterol level and triglyceride level in TⅡgroup were obviously lower than those in valsartan group(P<0.01). The total cholesterol level and triglyceride level in valsartan group increased ([6.60±0.2]mmol/L vs [7.11±1.13]mmol/L, [2.47± 1.48]mmol/L vs [2.49±0.32] mmol/L).The serum protein level in TⅡ group was obviously higher than that in valsartan group ([41.1±1.2]g/L vs [37.9±4.2]g/L, P<0.05).At 3 month, 6 month and 12 month follow-up, the average serum creatinine levels in TⅡgroup were obviously lower than those in valsartan group ([1.5±0.4]mg/dl vs [1.6±0.3]mg/dl, P<0.05), ([1.3±0.3]mg/dl vs [1.8±0.5]mg/dl, P<0.05), ([1.1±0.4]mg/dl vs [2.1±0.5]mg/dl, P<0.05).The incidence rate of adverse reaction in valsartan group was obviously greater compared with TⅡgroup( P<0.05) . Conclusion Both tripterygium wilfordii multiglycosides and valsar-tan can reduce proteinuria caused by SRL in renal transplant patients,while the application of TⅡhas more remarkable effect.

Objective To explore the expression and the pathomechanism of folate receptor alpha(FRα) and CA125 in the development and progression of endometrial carcinoma.Methods Sixty samples of endometrial carcinoma tissues,46 samples of endometrial hyperplasia tissues and 10 normal endometrial tissues were collected in the study.Immunohistochemical methods were used to detect the expression of Frαand CA125 in all tissues.The expressions of FRα and CA125 and their correlation with clinicopathological characteristics were analyzed.Results FRα was positively expressed in 93.9％ of the endometrial carcinoma tissues,with a strongly positive rate of 65.0％,which was significantly higher than that in endometrial hyperplasia tissues and normal endometrial tissues (P ＜ 0.05).The highly expressed FRαin endometrial carcinoma tissues was associated with age,FIGO stage and histologic types (P ＜ 0.05),while no statistical significance was found between the high expression of FRαand myometrial invasion.The expression of FRα in endometrial atypical hyperplasia was higher than that in other hyperplasia subgroups.The expression of CA125 in endometrial carcinoma tissues and endometrial hyperplasia tissues were both higher than that in normal endometrial tissues (P ＜ 0.05).Conclusion FRα may play an important role in the carcinogenesis and progression of endometrial carcinoma,and act as a target of therapy and a kind of assessment for prognosis in endometrial carcinoma.CA125 may be involved in the development of endometrial lesions and further researches are needed to confirm a physiological mechanism between FRA and CA125 in carcinogenesis of endometrial carcinoma.

Objective To investigate the renal pathologic changes in both donors and transplant recipients with delayed graft function (DGF).Methods The clinical and laboratory data were retrospectively analyzed in 144 renal recipients with DGF.All the patients received renal biopsy,and donors' biopsy was performed on 131 recipients.The pathological changes were examined under the light microscopy (LM),immunofluorescence (IF) and electron microscopy (EM).Results (1) The incidence of DGF was 10.16%-7.48% during 1994 to 2005,and decreased to 5.35 % during 2006 to 2009.(2) Anuria occurred in 24 cases (16.67 %),oliguria in 24 (16.67%) and hypertension in 68 cases (47.22 %).The enlargement of transplanting kidney and the increased vascular resistance was detected in 79.67 % (98/123 cases) and 45.53 % (56/123 cases) respectively by ultrasound examination.(3) The level of serum creatinine was ranged from 451 to 707 μmol/L.The high level of urinary NAG enzyme was found in 102 cases (70.83 %),proteinuria in 79 recipients (54.86 %) and hematuria in 77 cases (53.47 %).(4) The acute rejection was observed in 66 cases (45.83 %),toxicity of CNI in 22 (15.28 %),IgA nephropathy in 18 (12.50 %),acute tubular necrosis in 8 (5.56 %),and recurrent FSGS in 2 cases (1.39 %).(5) In most recipients (66/109 cases,60.55 %)immunosuppressive regimen altered and renal replacement therapy was given.Conclusion The causes of DGF are complicated.The quality of donors' kidney and early histological changes of recipients are contributed to the development of DGF.It is necessary to perform renal biopsy not only in donors but also in recipients with DGF.And kidney biopsy in transplanted patients was also beneficial to the treatment.

Objective To compare the degree of coronary lesions in different types of heart failure with ischemic heart disease. Methods This retrospective analysis include 282 cases diagnosed as heart failure with ischemic heart disease in Zhengzhou People′s Hospital from January 2015 to May 2016. Based on LVEF and the level of BNP and NT-proBNP examination results ,282 cases were divided into HFmrEF(89 cases),HFrEF(109 cases) and HFpEF (84 cases). The clinical basic data ,cardiac color Doppler ultrasound and the difference of coronary artery lesions were compared. Results (1) HFpEF,HFmrEF and HFrEF groups gensini score were 30.45 ± 33.18,62.12 ± 41.25,86.72 ± 38.80. The differences are significant(P < 0.05). Pairwise comparison showed significant difference.(2)HFpEF,HFmrEF and HFrEF groups SYNTAX score were 11.77 ± 8.39,19.08 ± 8.39,26.41 ± 10.31. Compared with HFpEF group,the SYNTAX score of other groups are higher(P < 0.05). (3)The duration of disease ,LVEDD ,LVESD ,LVMI ,the number of vascular lesions was significantly higher in HFrEF group than those in other groups. (4) Multivariate correlation analysis suggested that SYNTAX scores were related to cardiac function classification,BNP,NT-proBNP and LVEF. Gensini integral is related to cardiac function classification ,BNP and NT-proBNP. Conclusions With the severity and complexity of coronary artery disease,the degree of heart failure is more serious. The complexity and severity of coronary artery disease is an important factor in heart failure in patients with ischemic heart disease.

Objective To study the therapeutic window of rapamycin(RPM) concentration in primary recipients of renal transplantation. Methods An open label, multi center study was performed. One hundred primary renal allograft recipients with cadaveric donors were enrolled from 4 transplantation centers in China. The immunosuppressive regimen was triple therapy,i.e.RPM combined with CsA and steroid. A loading dose of RPM 6 mg/d was administered within 48 hours after transplantation, then a maintaining dose of 2 mg/d was administered. The whole blood concentration of RPM was measured by HPLC method. Results The whole blood concentration of RPM in this group was (6.65?2.75)ng/ml, the 10th and 90th percentile for RPM concentration was 3 2 ng/ml and 10 26 ng/ml,respectively.9 5%(8/84)patients suffered from acute rejection during the 6 month period after transplantation in this study, and the concentration of RPM in these was lower than that in non rejection patients(P=0.001). Hyperlipidemia and liver dysfunction were the most frequently adverse events, and RPM concentration was significantly associated with the concentration of triglyceride. Conclusions 4～8 ng/ml is a suitable level for RPM concentration. Regular drug monitoring and reasonable dose modulation may increase the validity and security of RPM.
