Objective To investigate the diagnostic value of the real-time tissue elastography (RTE)and AST/PLT ratio in-dex (APRI)for the assessment of the early stage liver fibrosis in chronic liver disease patients.Methods Totally 90 patients with chronic liver disease were enrolled in the present study.The RTE score and the area percentage of the blue color (AREA,one of the elastic characteristics),the AST and PLT were recorded.Compared the results among different stages of liver fibrosis reported by biopsy considered as the gold standard for the assessment of liver fibrosis.The accuracy of the diagnosis of liver fibrosis by RTE scores,AREA and APRI were compared.Results RTE scores,AREA and APRI increased with the stage of liver fibrosis. Taking ≥S1 as the diagnosis standard of the early stage liver fibrosis,the area under the curve of ROC for RTE scores,AREA and APRI were 0.88,0.92,0.76 (P <0.05).Conclusion RTE is a new and promising sonography-based noninvasive method for the assessment of hepatic fibrosis in patients with chronic liver disease.Combined RTE with APRI have great clinical significance in di-agnosing the early stage liver fibrosis in chronic liver disease patients.

Chronic kidney disease(CKD)is a major public health problem worldwide. Understanding by doctors and laboratorians of the importance of reliable serum creatinine measurement in GFR estimation and of factors that may affect creatinine measurement is critical to ongoing public health efforts to improve the diagnosis and treatment of patients with CKD.We present an overview of the commonly used methods,their performances and limitations and the required performance criteria for the measurement of serum creatinine.Available resources for standardization of serum creatinine measurements and recommendations for creatinine measurement and GFR estimations are introduced.

Objective To explore the optimal cut-off points of body mass index(BMI),percentage of body fat(PBF) and body fat mass index(BFMI) for identification of cardiovascular risk factors clustering among elderly males. MethodsThe data of physical examinations from 1 052 Shanghai elderly males in 2007 were collected.The relationship between cardiovascular risk factors clustering and different strata of BMI,PBF and BFMI was analyzed.Receiver Operator Characteristic(ROC) curve analysis was employed to determine the optimal cut-points for identification of cardiovascular risk factors clustering,and area under curve(AUC) was worked out.The population attributable risk proportion(PARP) of risk factors clustering was calculated. Results Odds ratios of risk factors clustering tended to increase with BMI,PBF and BFMI.BMI≥24 kg/m2,PBF≥21% and BFMI≥5 kg/m2 were the cut-off points that had approximate sensitivity and specificity,and/or had the shortest distance in ROC curve.AUC of all the three indexes was larger than 0.5.Analysis of PARP indicated that BMI under 24 kg/m2,PBF under 21% and BFMI under 5 kg/m2 could prevent 27.1%,37.44% and 36.63% risk factors clustering,respectively. Conclusion BMI≥24 kg/m2,PBF≥21% and BFMI≥5 kg/m2 can well reflect the cardiovascular risk factors clustering among elderly males.

0.05).The incidences of ADR in the two groups(17.24% vs.14.81%) were near to each other.CONCLUSION: The esomeprazole enteric-coated capsules and esomeprazole magnesium-based triple therapy regimens are therapeutically equivalent in the eradication of Hp and it has a good safety.

Objective:To investigate whether chemokine like factor (CKLF)-like myelin and lympho-cyte and related proteins for vesicle trafficking and membrane link (MARVEL)transmembrane domain-containing protein 2 (CMTM2)is involved in spermatogenesis in varicocele induced sub-fertility rats and to discuss the possible mechanisms.Methods:Forty male SD rats (body weight:220 -330 g,age:6 -7 weeks)were randomly divided into 4 groups:varicocele for 4 weeks,varicocele for 12 weeks,sham operation for 4 weeks and sham operation for 12 weeks,with 10 rats in each group.These rats were intro-duced by partially ligating left kidney veins for the experimental groups,and the sham surgery groups as controls were executed with exactly the same surgery as in the experimental groups except for the ligation. The rats in control and experimental groups for 4 and 12 weeks were killed after laparotomy at the end of 4 and 12 weeks,respectively,the left testes and epididymis were taken out for counting the sperm,ob-serving the seminiferous tubule change and immunochemistry for CMTM2.The changes included sperm density and motility,the outer diameter and inner diameter change and the changes of epithelium and the CMTM2 expression in immunochemistry.Results:Compared with the control groups,the sperm density [(63.9 ±7.1)×106 /mL vs.(74.3 ±5.0)×106 /mL]and motility[(58.7% ±7.9%)vs.(66.1% ± 4.3%)]were reduced slightly in group of varicoele for 4 weeks,respectively (t =1.432,1.563;P =0.076,0.059,respectively ).Varicocele significantly caused a decrease in sperm concentration [(40.5 ±7.2)×106 /mL vs.(71.1 ±4.5)×106 /mL]and motility [(35.2% ±8.5%)vs.(63.4% ± 4.1%)]at 12 weeks,compared with the related sham groups (t =3.754,3.933;P =0.004,0.002, respectively).Additionally,testis CMTM2 exhibited the same disparity,that is,the CMTM2 protein ex-pression in varicocele group was significantly reduced,with the ratio of sham group to varicocele group at the end of 12 weeks 2.3 ±0.4 (t =1.978;P =0.039).In the evaluation of seminiferous tubules diame-ter,the external [(198.2 ±10.2)μm vs.(255.8 ±12.7)μm,t =2.125,P =0.003]and epithelium diameter [(54.1 ±1.5)μm vs.(75.5 ±4.1)μm,t =2.246,P =0.021]were decreased compared with the sham-related groups and previous varicocele groups.In all the varicocele groups,all types of sperm motility decreased compared with the related sham-operated group (P <0.05).Conclusion:This study suggests varicocele has a detrimental effect on CMTM2 levels and decreases spermatogonia cell number,seminiferous tubules diameter,and sperm indices.CMTM2 is associated with sperm changes in rats with varicocele,and further studies are needed to study the mechanism.

To analyze features of the rabies epidemic in China between 2007 and 2011,identify factors influencing the epidemic and to provide a scientific basis for further control and prevention of rabies,Descriptive epidemiological methods and statistical analysis was used on data collected from the National Disease Reporting Information System between 2007 to 2011 and the National Active Surveillance System between 2007 and 2010.Our analysis shows that while the number of human rabies cases decreased year by year,the number of districts reporting cases did not show significant change.The situations in Guangdong,Guangxi,Guizhou and Hunan provinces clearly improved over the period but they remain provinces with high-incidence,and consequently influence the epidemic situation of surrounding provinces and possibly the whole country.Summer and autumn were high-incidence seasons.Farmers,students and pre-school children represent the high-risk populations,and rates of cases in farmers increased,those for students decreased,and pre-school children remained unchanged.Provinces with active surveillance programs reported a total of 2346 individual cases,of which 88.53％ were associated with canines.Postexposure prophylaxis (PEP) of rabies cases was not significantly improved,whereas PEP in post-exposure population was good.In rural regions of China,canine density was reduced somewhat,and the immunization rate increased slightly.Finally we show that while the epidemic decreased 2007 to 2011 in China,cases continued to be diffused in certain regions.Lack of standardization of PEP on rabies cases was the main reason of morbidity.The high density and low immunization of dog in rural areas and the defective situation of PEP are still continuous occurrences in China and remain a cause for concern.
