74 years were associated with increased cardiac events too(HR = 5.40,95%CI:2.16~11.52,P=0.0002).NYHA classification, LVEF, cTnT?cTnI and CK-MB were not independently predictive of cardiac events.Conclusions Measurement of NT-proBNP in patients with CHF can help to identify patients at higher risk for cardiac events .

Objective To investigate the influence of renal function on serum NT-proBNP in the diagnosis of chronic heart failure by observing the relationship between eGFR and NT-proBNP in serum and comparing cutoff values of NT-proBNP in different eGFR levels.Methods 297 elderly participants were enrolled in the study, including 106 inpatients with heart failure and 191 healthy controls in the corresponding period.The concentration of NT-proBNP was determined by an automated electrochemiluminescence immunoassay on Roche Elecsys 2010.Estimated glomerular filtration rate (eGFR) was calculated using the Levey-modified Modification of Diet in Renal Disease formula. The diagnosis of clinical physician was considered to be the golden standard for heart failure.Results Serum NT-proBNP levels were significantly higher in subjects with renal dysfunction compared with those with normal renal function for heart failure patients [829.1 (202.4 ~ 3725.5) ng/L vs. 227.2 (111.1 ~ 964.2) ng/L, P

OBJECTIVE:To develop the drug traceability management system in outpatients of medical institutions,and gradu-ally improve its traceability management. METHODS:Based on barcode technology,drug traceability management system in outpa-tients of medical institutions was independently developed,introducing it from system environment,framework design and system function,and the application results were evaluated in terms of differences in dispensing time,deployment error,drug withdrawal treatment and applicability investigation. RESULTS:The system was developed on hospital information system network environ-ment,which was designed by combination of client/server(C/S)network system(B/S)and set function modules as follows as role rights management,data extraction,information control,data acquisition and data query. The system can match with drug electron-ic surveillance code,commodity code and other traceable barcodes,achieve drug tracing from hospitals to users through software interaction,as well as the computer-aided calibration in dispensing to effectively reduce outpatient's dispensing error. The average time for each outpatient prescription prolonged 9 s after using the system;24 dispensing errors and 4 non-normal withdrawals were prevented within 1 month;100% surveyed pharmacists expressed approval for the system's applicability. CONCLUSIONS:The system can achieve the drug suitability management in outpatients,which has shown good applicability and further improved drug safety management and control capabilities in medical institutions.

Objective To assess the clinical significance of antibodies against cyclic citrullinated peptide(anti - CCP) in a cohort of patients with juvenile idiopathic arthritis (JIA). Methods The anti - CCP was tested by an enzyme linked immunosorbent assay (ELISA) in serum samples from 22 patients with JIA(9 boys, 13 girls), with a mean age of 9.1 years(range 1.1 - 16). As control groups, anti - CCP were also tested in sera of 20 healthy children, and 30 adult patients with rheumatoid arthritis(RA). Results Positive anti - CCP were found in sera of 2 patients with JIA(9.1 %), both with lower titre comparing with those of adult patients with anti - CCP positive. In the control groups, none of healthy children was positive for anti - CCP, but 16/30(53. 3%) adults with RA showed anti - CCP positivity. Conclusion Anti - CCP can be detected in children with JIA, but are less frequently present than in adults with RA, so anti - CCP has limited diagnostic value to JIA.

Background Medical refraction after cycloplegia is the preferable choice for precise measurement of degree of refractive error.Drugs used in China for cycloplegia include atropine and tropicamide,and the use of cyclopentolate is an alternative for ophthalmologist.However,the data for the evaluation and comparison of efficacy of the available drugs in cycloplegia is still lacking.Objective This system analysis was to evaluate the difference between atropine and cyclopentolate in cycloplegia in children.Methods A systematic literature retrieval was conducted in MEDLINE,EMbase,Google residual accommodation after cycloplegia by atropine and cyclopentolate were compared.Statistical analysis was performed using the RevMan 5.1.0 software.Results A total of 7 studies were included in this meta analysis,including 6 cohort study design and 1 randomized,doubleblinded clinical trial and 1232 eyes.For retinoscopic evaluation after cycloplegia,no significant differences were found between cyclopentolate and atropine in children with hyperopia and myopia (WMD =-0.21,95％ CI:-0.47-0.06,P=0.13 ; WMD =-0.10,95％ CI:-0.36-0.15,P =0.43).For residual accommodation after cycloplegia,no significant difference was seen between cyclopentolate and atropine in ammetropic children (WMD =0.30,95％ CI:-0.10-0.71,P =0.15).Conclusions Cyclopentolate shows the same effect on the cycloplegia as atropine in children,and it can take the place of atropine in cycloplegia in childhood.

OBJECTIVETo analyze the changes of patients with type 2 diabetes in different stages in glucagon (GC) and free fatty acid (FFA) in fasting, OGT and L-Arg experiments, and discusses the role of pancreatic alphabeta cells in diabetes pathogenesis by studying the relations among indexes such as glucagon (GC), free fatty acid (FFA) and blood glucose (BG), insulin, insulin homeostasis model (HOMA) and glucose metabolism hormone secretion curve, in order to provide theoretical basis for the treatment of diabetes.

METHODStudy objects were divided into the T2DM group (45 cases), the IGT group (28 cases) and the NGT group (30 cases) for an OGTT experiment and then an L-Arg experiment on the next day. Under the fasting state, their blood glucose (FBG), insulin (F), glucagon (FGC), free fatty acid (FFA) were detected to calculate HOMA-beta, insulin sensitivity index (ISI) and HOMA-IR of different groups. Meanwhile, efforts were made to calculate different time quantum detected in OGTT and L-Arg experiments and area under the curve AUC(BG), AUC(INS) and AUC(GC).

RESULTObvious overall differences were observed in FFA and FGC of the three groups. FGC of each group was negatively correlated with HOMA-beta and ISI. Among all of the 103 study objects, FGC was positively correlated with FBG and HOMA-IR and negatively correlated with HOMA-beta and ISI, with no correlation with FINS; FFA was positively correlated with FBG, HOMA-IR and negatively correlated with FINS, HOMA-beta, ISI. FGC and FFA were positively correlated in the T2DM group and the IGT group, but with no statistical correlation in the NGT group. The sequence of the three study objects was T2DM > IGR > NGT in AUC(GC) in the OGTT experiment and T2DM > IGR > NGT in in AUC(GC) in the L-Arg experiment, with the significant positive correlation between AUC(GC) and AUC(BG) and significant negative correlation with AUC(INS).

CONCLUSIONGlucagon and free fatty acid of T2DM and IGT patients increased, which was positively correlated with blood glucose and HOMA-IR and negatively correlated with INS, HOMA-beta and ISI. The increase in glucagons of T2DM and IGT patients indicated inappropriate secretion of pancreatic alphabeta cells among patients with type 2 diabetes.

Objective To estimate the current quality of the reporting of randomized controlled trials (RCTs) related to digestive diseases in China. Methods All the papers related to RCTs published in Chinese Journal of Digestion from 1999 to 2008 were hand-searched by professional staff then evaluated and analyzed them according to the international reference standard. ResultsIn the 3298 issues of the recent ten years, there were 92 research papers of RCTs which was accounting for 2.8%. The sample size ranged from 18 to 5241. Sixty-one (66.0%) trials included the exact standard of internalize and exclusion. Sixteen (17.4%) trails told the specific method of random allocation and 22(23.9%) were double-blinded. Fifty-eight (63.0%) trials compared the baseline condition of each groups. Seventy-three(79.3%) trails showed the specific approach of statistic. In the end, only 7(5.7%) trails were identified as the strictly-designed RCTs. Conclusions The quantity and quality of the clinical RCTs can not satisfy the demand of clinical practice. Strictly-scientific designed, multicentered, large sample prospective clinical RCT should be advocated.
