Objective To analyze the epidemiographic features of malignant tumors of urinary system in renal allograft recipients in our center.Methods A retrospective analysis was performed on 3150 patients who received renal transplantation between June 1978 and Autumn 2006.Twelve cases of urinary tumors were selected for study.Results Among 3150 recipients,33(1.05%)were diag- nosed as malignancies including 12(0.38%)cases in urinary system.The mean age of these patients when diagnosed as urinary tumors was 58.3?4.6(range 48-66).The mean duration of immunosup- pressive treatment was 62?18(range 26-120)months.Six cases received cyclosporine A+azalthio- prine+prednisone(CsA+Aza+Pred),5 cases cyclosporine A+mycophenolate mofetil+prednisone (CsA+MMF+Pred),and one case tacrolimus+mycophenolate mofetil+prednisone(FK506+MMF +Pred).Surgical treatment was carried out in 11 patients.Ten of them were still alive.One case died of cerebral hemorrhage.Conclusions Malignant tumors of urinary system,especially TCC is an im- portant complication in renal transplantation in our center.The occurrence of malignant tumors is inti- mately related to immunosuppressive treatment.The immunological status of patients after renal transplantation should be evaluated in follow-up studies.The treatment consists of complete resection of the mass,decreases of immunosuppressants,chemotherapy or radiotherapy.

Objective: To modify EBP(endotoxin binding peptide), clone and express the mutate of EBP gene and gain purified mEBP.Method: mEBPgene was cloned by PCR site-directed mutagenesis. PinpointXa-3/mEBP expression vector was designed to express human mEBP as a fusion protein in BL21 (DE3) pLysS. Digested engineering bacteria by lysozyme and collected inclusion bodies.Fusion protein was purified by Pinpoint TM Xa purification system and cleaved by factorXa,mEBP was purified by RP-HPLC. Results: Mutations at residues 5 and 18(Gln→Lys) was obtained by PCR site-directed mutagenesis, expressed and purified mEBP successfully.Conclusions: Obtaining of purified mEBP lay a foundation for its biological activity research.

876 women with polycystic ovary syndrome (PCOS) were collected from Sep 2004 to Oct 2006. Among them 800 patients with polycystic ovary ultrasound image belonged to group A; the other 76 women without polyeystic ovary ultrasound image belonged to group B. As compared with group A, group B showed significantly higher hirsutism scores, serum testosterone, cholesterol, and lower density lipoprotein. Significantly higher prevalences of diabetes mellitus and hypertension appeared in the first degree relatives in group B than in group A.

OBJECTIVETo observe the effect of nourishing Yin, strengthening Qi and activating blood decoction on Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression.

METHODThirty-two NOD mice were randomly divided into the model group, the traditional Chinese medicine group (TCM group, orally given 0.4 mL nourishing Yin, strengthening Qi and activating blood decoction as per 100 g x kg(-1) everyday), the hydroxychloroquine group (given 0.4 mL hydroxychloroquine as per 60 mg x kg(-1) everyday), the traditional Chinese medicine and western medicine group (TCM WM group, given nourishing Yin, Strengthening Qi and activating blood decoction 50 g x kg(-1) and hydroxychloroquine 60 mg x kg(-1), 0.4 mL everyday), with eight mice in each group. Eight Balb/C mice were selected as the normal control group (normal group). All of mice were killed after eight weeks, and their submaxillary glands were dissected. The expression levels of Fas/FasL were examined by immunohistochemical method, and the FasL mRNA was detected by RT-PCR.

RESULTThe expression levels of Fas/FasL in salivary glands of the model group were higher than that of other groups (P < 0.05). The expression level of FasL of the normal group was much lower than that in the hydroxychloroquine group (P < 0.05). The relative expression level of Fas mRNA in salivary glands of the model group was higher than that in other groups, but the control group was notably lower than other groups (P < 0.05). The expression level of FasL mRNA in salivary glands of the model group was higher than that in TCM and TCM WM groups (P < 0.05). But the expression level in TCM WM group was notably lower than the hydroxychloroquine group (P < 0.05).

CONCLUSIONThe nourishing Yin, strengthening Qi and activating blood decoction could down-regulate the expression level of Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression, and had a better efficacy after being combined with hydroxychloroquine. The nourishing Yin, strengthening Qi and activating blood decoction might treat the Sjogren's Syndrome by reducing apoptosis which is regulated by Fas/FasL

OBJECTIVETo investigate the diagnostic value of MRI in radial head fracture with forearm interosseous membrane injuries.

METHODSFrom December 2011 to December 2012,26 patients with fractures of capitulum radial in our hospital were collected. There were 15 males and 11 females, ranging in age from 21 to 53 years old,with an average of 37.6 years old. All the patients visited hospital within 72 hours after injuries. X-ray radiography of full ulnar radial length in injured side, CT in injured side (three-dimensional reconstruction if necessary) and MRI (including the elbow and wrist joints) were performed within a week after the injury. The MRI manifestations of the forearm interosseous membrane (with or without damage, the injured location and the injury degree ) and the fractures degree of radial head were observed and compared for the relativity.

RESULTSRadial head fracture from Mason type I to III was associated with the forearm interosseous membrane injury. Radial head fracture degree was positive correlated with forearm interosseous membrane injury degree (P < 0.05).

CONCLUSIONRadial head fracture with suspicious forearm interosseous membrane injury is necessary to take MRI for checking for any interosseous membrane injury and injury degree, then choose the right treatment for radial capitulum fracture, only in this way can be helpful for the functional recovery of elbow and forearm.

OBJECTIVETo study the distribution of hepatitis B virus genotypes in Handan area and clarify the genotype-related difference in clinic.

METHODSPolymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) was used to detect the HBV genotypes in 108 HBV-infected patients from Handan area. The clinical significance of HBV genotype was analyzed in combination with the values of HBV DNA and ALT.

RESULTSAmong the 108 HBV-infected patients, the proportion of genotype B and C was 6.5 percent and 93.5 percent, respectively. Genotype distribution showed no significant difference between male and female patients. ALT and AST levels were higher in genotype C group than those in genotype B group.

CONCLUSIONHBV genotype C is predominant in chronic hepatitis B patients in Handan area. The positive rates of HBeAg and HBV DNA levels were higher in genotype C group than those in genotype B group. Genotype C was associated with the development of severe liver disease as compared to genotype B.

Fluid therapy is one of the most controversial topics in perioperative management. Current perioperative fluid therapy is largely based on concepts developed restricted and liberal perioperative fluid administration in the late 1950s and 1960s. However, there are increasing reports of perioperative excessive intravascular volume leading to increased postoperative morbidity and mortality. The concept of individualized goal-directed therapy in surgical patients seems to be an important component for optimization of perioperative fluid management in high-risk surgical patients.

Objective To identify novel proteins of human adipocytes by proteomic study,and analyze their strueture and function.Methods The expressed proteins of human adipocytes were identified by 2-D electrophoresis and mass spectrometry,and the structure and function of the novel proteins were predicated via bioinforrnatics.Results My027 is a novel protein of human adipocytes identified by 2-D electrophoresis and mass spectrometry.This protein was confirmed by RT-PCR,sequencing,and prokaryotic expression.My027 protein is located in the cytoplasm and has highly conserved structure,indicating that it is an important functional protein. This protein is highly homologous to glyoxalase superfamily with a whole domain of glyoxalase.It shares 96.7% homologous to glycoxalase between 141-253 amino acids and 95.7% homologous to glycoxalaseⅠbetween 144-244 amino acids.Conclusion The results show that protein My027 appears to have the same function as glyoxalaseⅠ.
