ObjectiveTo investigate the current status of Kaschin-Beck disease in Shandong province, and to provide a scientific basis for decision-making in controlling the disease. Methods According to the National Monitoring Program of Kaschin-Beck disease requirements, historical serious villages of Kaschin-Beck disease in Qingzhou of Shandong province were selected annually; children aged 7 to 16 were chosen to receive clinical examination and children aged 7 to 12 were taken X-ray examination. Clinical and X-ray diagnosis was carried out according to the Diagnostic Criteria of Kashin Beck Disease(GB 16003-1995). Results From 1996 to 2010, in 53 diseased villages, three thousand three hundred and eighteen school children aged 7 to 16 were clinically diagnosed, and child Kaschin-Beck disease of degree Ⅰ and above were not detected; three thousand and ninety-one school children aged 7 to 12 were examined by X-ray, forty cases were found positive, and the total positive rate was 1.29％(40/3091 ). The year with the highest positive rate was 2002, and the rate was 3.49％(13/372) ; the positive rate was 0 in 1996 and 2008. The difference of the X-ray positive rate between each year was statistically significant(x2 =31.54, P ＜ 0.01 ). ConclusionsChild Kashin-Beck disease in Qingzhou is basically under control.Since etiology of Kashin-Beck disease is still unclear, surveillance of the disease still needs to be strengthened.

We determined molecular characteristics of Listeria monocytogenes foodborne isolates in Hangzhou and investigated the characterization of local strains.Multi-locus sequence typing(MLST) and pulsed-field gel electrophoresis(PFGE) were applied to identify molecular types of Listeria monocytogenes isolates.Results showed that a total of 133 strains of 6 serotypes were divided into 19 MLST types including a new type ST767.ST9 and ST121 were the major ST types.There were 33 and 45 PFGE patterns characterized by AscⅠ and ApaⅠ.The molecular types of Listeria monocytogenes strains were widely distributed in Hangzhou.It is indicated that the major clusters were Lineage Ⅰ and Lineage Ⅱ which will cause listeriosis.The contamination of Listeria monocytogenes in food is serious in Hangzhou and the surveillance and management should be strengthened to prevent the food borne diseases.

Objective: To investigate the value of serum hepcidin in assessment of liver inflammation activity among patients with chronic hepatitis B ( CHB ), so as to provide insights into the assessment of liver inflammation activity among CHB patients. Methods: A total of 79 CHB patients who were admitted to the Affiliated Hospital of Hangzhou Normal University were selected as the experimental group, while 40 healthy volunteers were randomly sampled as controls. Subjects'demographic data, liver function tests and iron metabolism parameters were collected from medical records, and serum hepcidin was measured using enzyme-linked immunosorbent assay ( ELISA ). In addition, ultrasound-guided liver biopsy was performed in CHB patients, and mild and moderate-to-severe CHB were classified according to liver inflammation activity and degree of liver fibrosis. Serum hepcidin levels were compared between the experimental and control groups and between patients with mild and moderate-to-severe CHB. The value of serum hepcidin in assessment of liver inflammation activity was examined among CHB patients using the receiver operating characteristic ( ROC ) curve analysis. Results: Subjects in the experimental group included 54 men ( 68.35% ) and had a mean age of ( 39.06±10.67 ) years, while the controls included 24 men (60.00%) and had a mean age of ( 42.43±11.44 ) years. Lower hepcidin levels were measured in the experimental group than in the control group [( 11.70±5.64 ) vs. ( 17.82±3.63 ) μg/L; P<0.05 ]. There were 54 patients with mild CHB ( 68.35% ) and 25 cases with moderate-to-severe CHB ( 31.65% ), and lower hepcidin levels were detected in patients with moderate-to-severe CHB than in those with mild CHB [ ( 6.92±2.21 ) vs. ( 13.95±5.36 ) μg/L; P<0.05 ]. The area under the ROC curve, optimal cut-off, sensitivity and specificity of serum hepcidin were 0.903 ( P<0.05 ), 10.365 μg/L, 100.0% and 72.2% for assessment of moderate-to-severe CHB, respectively. Conclusion Serum hepcidin is feasible to evaluate the liver inflammatory activity among patients with CHB.

OBJECTIVETo investigate the influence of total flavonoids of epimedium (TFE) on the streptozocin (STZ)-induced kidney injury in diabetic rats and discuss the possible mechanism.

METHODSDiabetes was produced by a single injection of streptozocin (40 mg/kg, iv) in male SD rats. The rats were randomly divided into three groups (n = 10): control group, model group and TFE group (100 mg/kg, ig). Animals were sacrificed 12 weeks later. The level of blood glucose, blood urea nitrogen (BUN) and creatinine (Cr) as well as the renal index were determined. Detect the specific biochemical of renal tissue: superoxide dismutase (SOD), malondialdehyde (MDA). Use masson staining to observe the morphology of the renal tissue. Immunohistochemistry was employed to determine the protein levels of transforming growth factor-beta1 (TGF-beta1).

RESULTSCompared to control group, the enhancement of blood glucose, renal index, BUN and Cr was found in model group, which was significantly attenuated by treatment with TFE. Meanwhile, elevated MDA level in renal tissue as well as decreased SOD activities in renal tissue were significantly remitted by TFE. Furthermore, TFE decreased the expression of TGF-beta1.

CONCLUSIONTFE can evidently relieve renal damage in rats with diabetic nephropathy induced by STZ, which might be related to antioxidation and modulating the expression of TGF-beta1 protein.

Objective To investigate the value of percutaneous balloon dilation and percutaneous transhepatic cholangial drainage (PTCD) catheter maintenance in the treatment of benign biliary strictures.Methods The clinical data of 21 patients with benign biliary strictures at Peking Union Medical College Hospital from June 2005 to June 2011 were retrospectively studied,in which 12 patients in severe stricture (stenosis ＞ 70％ ) were treated with percutaneous balloon dilation and PTCD catheter placed across the stricture,while another 9 patients in median stricture( stenosis ＜ 70％ ) were only treated with PTCD catheter maintenance.Results Of the 12 patients underwent balloon dilation and 6-12 months ( median:9 months)of PTCD catheter placement,11 patients had the catheter successfully removed.In the follow-up of 6-24months ( median:10 months),patency of bile duct was preserved in 9 of 11 patients,and recurrent stenosis was seen in 2 patients.A severe complication with biliary artery branch rupture and massive hemobilia was seen in 1 patient during balloon dilation.Of the 9 patients only treated with 1-12 months (median:6months) of PTCD catheter placement,7 patients had the catheter successfully removed.In the follow-up of 5-18 months (median:8 months),patency of bile duct was preserved in 5 of 7 patients,and recurrent stenosis was seen in 2 patients.No severe complication occurred.Conclusions When endoscopy therapy is failed or the patient can't undergo endoscopy therapy,the percutaneous balloon dilation and PTCD catheter maintenance method is an effective alternative therapeutic approach in the treatment of benign biliary strictures.The moderate benign biliary stricture may be effectively treated only by the PTCD catheter maintenance method.
