ObjectiveTo investigate DNA loads and risk factors of BK virus infection in renal transplant recipients.MethodsWe developed a real-time PCR assay to quantitate BK virus loads in 80 patients receiving renal transplantation in our center,and correlation between the BK virus load and clinical course was analyzed.BK virus loads were measured in urine and plasma. Epidemiological features and risk factors of BK virus infection were analyzed.ResultsThe positive rate of BKV viruria and viremia in 80 renal recipients was 37.5％ (30/80) and 8.75％ (7/80),respectively.BKV loads were higher in renal allograft recipients whose age was more than 50 years old.BKV loads were observed in urine and plasma (compared with group whose age was less than 50 years,P=0.017 and 0.05,respectively).BKV DNA copies were higher in group Tac than that in group CSA (P＜0.05),and the peak of BKV load in serum appeared at14th and10th month after transplantation,respectively,but the peak in urine was ahead of that in serum,appeared at 2nd and 8th month,respectively.ConclusionSerial measurement of BKV viral loads by quantitative PCR is a useful tool in monitoring the course of BK virus infection.The ages of recipients (＞50 years) and using Tac + MPA can reactivate BK virus and then result in BKVAN in renal transplant recipients. Intensive BKV monitoring is necessary for these recipients.

Objective To investigate the signal transducer and activator of transcription 1(STAT1) and matrix metalloproteinase 3(MMP3)′s genetic expressions and their clinical significance on urothelial carcinoma after renal transplantation. Methods Fifty-one patients with urothelial carcinoma were recruited in this study. Sixteen of them who had renal transplant were in the experimental group and 35 of them without renal transplant were in the control group. All the cases had been proved postoperatively having transitional cell carcinoma by histopathological study. The human genome oligo arrays were used to analyze the gene expression spectrum of urothelial carcinoma after transplantation, aiming the STAT1 and MMP3's expression. Real time RT-PCR and immunohistochemical staining were used to compare the differences in the 2 groups. Results The experimental group showed that there were 35 genes up-regulated compared with the control group. Of them, 23had known gene function or partly known, and 12 had unknown gene function. There were 76 genes down-regulated. Of them, 46 had known gene function or partly known, and 30 had unknown gene function. After pathway analysis of the differentially expressed genes, there were 23 groups of pathways which had significant differences (P＜0.05), referring to the aspects of immunosuppressive and tumor growth. The levels of STAT1 and MMP3 expressions had significant differences between the 2groups(P＜0.05)as well. Conclusions The differential expression of urothelial tumor genes is obvious between patient who has had renal transplant and who has not. There are many aspects that are related to the tumor's growth like signaling pathways regulating proliferation, apoptosis of tumor cells, tumor angiogenesis and the tumor metastasis potential. STAT1 and MMP3 maybe become the targets of chemoprevention for post-transplantation urothelial carcinoma.

BACKGROUND: Documents recorded that the correlation between micro emulsion Ciclosporin peak concentration (C_2) and area under curve was best with maximum individual difference. According to C_2, dose of Ciclosporin can be adjusted indMdually to decrease acute rejection and Ciclosporin toxicity, which has widely used in perioperative stage of renal transplanted recipients. However, some transplantation center still used tough concentration (C_0) to adjust the dose of Ciclosporin in stable stage of renal transplanted recipients. OBJECTIVE: To analyze the efficacy and safety of changing from monitoring C_0 to C_2 in stable stage recipients following renal transplantation. METHODS: Totally 65 patients with renal transplantation were enrolled in this study, including 31 males and 34 females, aged 20-57 (39.4±15.3) years. Within 3 months prior to this study, all patients did not suffered from rejection, and their serum creatinine and urea nitrogen were stable (creatinine ≤180 μmol/L). They were in stable stage after renal transplantation. Their period of transplantation and function of allograft were recorded. Their C_0 and C_2 of Ciclosporin were assayed. According to the target C_2 value 500-600 μg/L, the patients were prospectively and randomly divided into 3 groups. In the high C_2 group (n=17), the dose of Ciclosporin was decreased. In the target C_2 group (n=23), the dose of Ciclosporin was remained. In the low C_2 group (n=25), the dose of Ciclosporin was increased. All of the patients were followed-up for 12 months. The grafts function and the complications of heart, lung and brain were compared. RESULTS AND CONCLUSION: According to the target concentration of Ciclosporin C_2, the dose of Ciclosporin in the high C_2 group was decreased by 575.0 mg. The Creatinine and urea nitrogen of 88% patients were stable, while blood pressure, blood fat and blood uric acid decreased in parts of patients. In the target C_2 group, the levels of creatinine, urea nitrogen, Co and C_2 of patients were stable, no complications of heart, lung and brain occurred. According to the target concentration of Ciclosporin C_2, the dose of Ciclosporin in low C_2 group was increased by 755.0 mg. The creatinine and urea nitrogen of 84% patients were stable. All of the patients were no complications of heart, lung and brain. It is safe and effective to adjust Ciclospori dose under C_2 monitoring according to the target peak concentration (500-600 μg/L) in most stable stage recipients following renal transplantation.

OBJECTIVETo observe the clinical efficacy of treating chronic persistent bronchial asthma (CPBA) children with abnormal myocardial enzyme spectrum (AMES) by Yupingfeng Powder (YP) combined routine therapy.

METHODSFrom January 2010 to December 2012, 156 CPBA children patients with AMES were randomly assigned to the treatment group (80 cases) and the control group (76 cases). All patients received routine treatment (inhaled corticosteroids and/or leukotriene regulator). Besides, those in the treatment group took YP. The treatment duration was 3 months. The scores of children asthma control test (C-ACT), pulmonary function (FEV,% and PEF%), myocardial enzyme spectrum were observed before and after treatment, and 3 months before and after treatment. The myocardial enzyme spectrum of 40 healthy children at the baby clinics during the same period were recruited as the control.

RESULTSCompared with the control group, creatine kinase isoenzyme (CK-MB), creatine kinase(CK), and lactate dehydrogenase (LDH) increased in the two treatment groups (P <0.01), but there was no statistical difference in AST (P >0.05). Compared with before treatment in the same group, CK-MB, CK, LDH, and AST decreased in the treatment group after treatment and 3 months after treatment (P <0.01). CK-MB, CK, LDH, and AST decreased in the control group 3 months after treatment (P <0.01, P <0.05).Compared with after treatment, CK decreased in the control group 3 months after treatment (P <0.01). C-ACT score, FEV(1),%, and PEF% all increased in the two groups after treatment and 3 months after treatment (P <0.01, P <0.05). Compared with after treatment in the same group, CK decreased in the control group 3 months after treatment (P <0. 01). Compared with the control group in the same period, post-treatment CK-MB and CK decreased (P <0. 01, P <0. 05), while post-treatment C-ACT score, FEV, %, and PEF% increased (P <0.05) in the treatment group (P <0.05).

CONCLUSIONYP could strengthen specific and non-specific immunity of the organism, and improve clinical symptoms and the level of myocardial enzyme spectrum.
