Objective To discuss the value of clinical application with Hcy enzymatic cycling assay.Methods To compare the results between enzymatic cycling assay and FPIA.The precision test and correlation test of enzymatic cycling assay were evaluated at Hitachi 7600-DDP automatic Biochemistry analyzer.Serum Hcy concentration of patients with diabetes, hypertension, coronary heart disease, myocardial encephalon infarction or chronic renal function failure had been detected in parallel with enzymatic cycling assay and FPIA and the results had been compared to the healthy.Results The within-run imprecision (CVs) of patient serum is 3.07%(low value ), 3.99%(mid value) and 4.21%(high value ). The between-run imprecision (CVs) is 4.00%(low value), 4.79%(mid value) and 4.58%(high value). The correlation of enzymatic cycling assay and FPIA was excellent(r=0.994,n=53).The averages of Hcy concentration in healthy, diabetes, hypertension, coronary heart disease, myocardial or encephalon infarction or chronic renal function failure respective were (8.15?1.89) ?mol/L, (8.88?1.36) ?mol/L, (10.66?1.60) ?mol/L, (14.02?3.42) ?mol/L, (14.45?3.83) ?mol/L and (15.21?3.50)?mol/L. There is no significant statistic difference between enzymatic cycling assay and FPIA.Conclusion The variation profile of Hcy concentration in different diseases detected by enzymatic cycling assay were similar to FPIA.The results indicated that en{ymatic cycling assay could be used to detect serum concentration of Hcy for clinical laboratory rapidly.

Objective To investigate the effects of micro alcohol on serum enzymes in vitro and vitro Methods Serum alcohol and ALT?AST?GGT?ALP?CK?LDH?AMY?LIPA activities were measured before and after alcohol consuming (1 ml/kg) in 14 volunteers Meanwhile, the direct inhibitory effects of alcohol on the serum enzymes were studied by comparing the serum enzyme activities with or without alcohol Results Alcohol consuming could depress the serum AST activity from (24 04?3 66) U/L to (22 25?3 27) U/L and LIPA activities from (155 86?93 51) U/L to (128 35?84 85) U/L, whereas increase the other serum enzyme activities, but only serum AMY were found statistic difference [from (48 78?10 66) U/L to (55 50?12 60) U/L] The inhibitory effects of alcohol on all the measured enzymes were found in vitro studies Conclusions Alcohol could obvious influence the serum enzyme activities both in vivo and vitro Avoiding the contamination of alcohol during sample collection and routine laboratory work is necessary

Objective To analyze the clinical significance and correlation factors influencing the serum levels of CA125 and CA199 in patients with chronic nephropathy.Methods Clinical data of 649 hospitalized patients with chronic nephropathy from Jan.to Dec.in 2007 were retrospectively analyzed.The criteria of enrolment were: patients with chronic nephropathy aged below 70 years,tumor excluded by CT and ultrasound,and virus hepatitis and tuberculosis excluded by microbiological examinations.The serum levels of CA125,CA199,albumin,total cholesterol(TC),triglyceride(TG),24h urine protein and urine creatinine(Cr) were determined.The patients were divided into CA125/CA199 positive group and negative group according to the cutoff value of serum CA125 and CA199,and the clinical differences were analyzed by t or ?2 test.The correlation factors influencing the serum levels of CA125 and CA199 were analyzed by multiplicity.Results The ratio of female,nephrotic syndrome(NS),membranous nephropathy(MN) and hydrops of serous cavity were significantly higher in CA125/CA199 negative group than that in positive group(P

0 05), there had slight interference to low value serum and had no interference to high value serum by 125 mg/L Vitamin C, the correlation of UIBC reagent kit from different manufacturer was excellent( r = 0 994 4, n = 198) UIBC of serum samples from100 health blood donors (19 years old to 52 years old) were determined with UIBC reagent kit, and the reference result is 26 0-51 0 ?mol/L( ? 2 s ) Conclusion The UIBC result determined by this method is exact and reliable The UIBC reagent kit is easy to operate and ready for automated analyzer Then UIBC assay is worth to popularize

As a powerful reserve force for primary care institutions, general practitioners (GPs) undergoing standardized training will be essential to solve the pediatric problems of first visit to primary medical institutions and coordinated care delivery system in the future, which puts forward new require-ments for the training of post competencies of GPs.However,the training and evaluating systems for GPs in Pediatric Department still need further exploration. This article tried to summarize the two-month rotating arrangement and its advantages for GPs in Pediatric Department of a general hospital.Based on the forgotten theoretical knowledge,superficial understanding of the diseases and individual teachers' poor teaching moti-vation, this article suggested reinforcing the theoretical basis of GPs through exploring multiple learning channels and increasing self-learning enthusiasm,strengthening the training and rewarding system of teachers to promote the specialist-GPs teaching, as well as promoting the set-up of Department of General Practice and taking the advantage of key disciplines in teaching hospitals to develop characteristic teaching model of general practice.

The ability of prevention, treatment and management of infectious diseases is a basic requirement for general practitioners. This article introduces our experience in the infectious disease rotation for general practice residency training, focusing on the rotation management at different stages of training to explore how to improve teaching quality and the ability of trainers in a short period of the rotation.
