Aim To investigate the changes of content of L-carnitine (LC ), acetyl-L-carnitine (ALC ) and propionyl-L-carnitine (PLC )in patients with diabetes and its complications.Methods By replicating meth-od of pre-column derivatization HPLC,the contents of plasma LC,ALC,PLC were detercted in normal sub-jects and in patients of diabetes mellitus,diabetic reti-nopathy, diabetic nephropathy, diabetic peripheral neuropathy,diabetic hypertension,diabetic coronary heart disease.Results The concentration of LC in normal subjects and in patients of diabetes mellitus, diabetic retinopathy, diabetic nephropathy, diabetic peripheral neuropathy,diabetic hypertension,diabetic coronary heart disease were (41.01 ±8.05 )μmol · L-1 ,(36.72 ±8.23 )μmol · L-1 ,(33.3 1 ±6.26 )μmol·L-1 ,(33.81 ±5.61 )μmol·L-1 ,(33.57 ± 6.67 )μmol · L-1 , (33.67 ±5.36 )μmol · L-1 , (32.87 ±6.05 )μmol · L-1 respectively.The plasma LC concentration in diabetic group was significantly lower than that of normal control group (P<0.05 ). Moreover,the LC concentration in other groups of dia-betic complications was lower than that in diabetic group, and LC concentration showed no significant difference in various groups of diabetic complications. There was no significant difference in the plasma con-centrations of ALC and PLC of diabetes group and the diabetic complication groups too.Conclusion In Chi-nese normal subjects,patients with diabetes and dia-betic complications,the plasma concentrations of LC in diabetic patients are lower than normal,and plasma concentration of LC in diabetic complications are lower than that in patients with diabetes mellitus.

BACKGROUND: When the dynamic equilibrium between oxidation system and anti-oxidation system in the body is upset, the overly produced active oxygen-derived free radicals will attack the target organs, thus resulting in the damage to organs and big molecules, and then diseases. Total anti-oxidation capacity (T-AOC), superoxide dismutase (SOD), and nitric oxide synthase (NOS) activity are the majorindexes for the defense system of the body, and their status is closely related to diseases. OBJECTIVE:To explore the level of T-AOC, SOD and NOS in serum,and find out its relationship with lifestyle. DESIGN:Single sample investigation. SETTING:Department of Health Laboratory Technology, College of Public Health of Harbin Medical University. PARTICIPANTS:Totally 531 residents of Bin County aged 20 to 70years were recruited between September 2000 and May2001. MATERIALS:The reagents kits of T-AOC, SOD and NOS were manufactured by Nanjing Jiancheng Bio-engineering Institute. METHODS:The investigators surveyed the residents with the same questionnaire. Questionnaire was made and the investigators were trained in advance. The questionnaire was filled in item by item as required. Questionnaire items consisted of the general situation, financial status, dietary habit, hobby, status of health care, and mental factor. Finally 95 investigation indexes were completed. The activity of serum T-AOC, SOD and NOS of the 531 residents in Bin County was determined, respectively, with reagent kits produced by Nanjing Jiancheng Bio-engineering Institute. The lifestyle factors were analyzed by multivariate stepwise regression analysis,and informed consent was obtained from the participants. MAIN OUTCOME MEASURFS:① Serum T-AOC, SOD and NOS in the participants; ② lifestyle factors affecting T-AOC, SOD and NOS.RFSULTS:According to actual analysis, the 531 participants entered the results analysis. T-AOC was measured in 489 participants, SOD in 525participants, and NOS in 531 participants. ① Indexes of the participants:T-AOC of the males was obviously higher than that of the females [(20.01±7.21), (15.25±6.22) kU/L, P ＜ 0.05]. SOD of the males was slightly lower than that of the females while NOS of the males was slightly higher than that of the females, but there was no significant difference. ②Multivariate stepwise regression analysis showed that risk factors related to T-AOC were gender difference (OR=2.188), educational level (OR=1.859),and the presence of rheumatism, respectively (OR =1.142). SOD-related risk factors were educational level (OR=1.584), years of spirit drinking (OR =1.048), presence of nephritis (OR=1.093), and irradiation (OR=1.770);frequency of tea drinking was a beneficial factor (OR=0.800). NOS-related risk factors were the average amount of cigarette smoking (OR=1.194) and the times of weekly spirit drinking (OR=1.368). However, the beneficial factor that affected serum NOS was the frequency of weekly mutton eating (OR=0.458) CONCLUSION:This experiment revealed that the ability to clean free radical in the 531 subjects was good and that it was better in males than in females. The increased educational level and presence of rheumatism can decrease T-AOC. Drinking, smoking and irradiation decrease SOD activity while the frequency of tea drinking and mutton eating are beneficial factors.

ObjectiveTo investigate the sleep status and effect of night shift work on sleep in nurses.MethodsSleep characteristics and qualities of 348 nurses, 50 communication persons and 100 night-guards were analyzed with Pittsburgh Sleep Quality Index (PSQI), and insomnia was diagnosed based on DSM-IV criteria.Results71.86% of nurses had bad sleep quality (PSQI>7); the rate of insomnia was 38.22%. The same data were 74% and 48% respectively in communication persons, and 26.76% and 7% in night-guards. The sleep quality of nurses was related to age and years of night shift work. The sleep quality of nurses was similar to communication persons (P>0.05), but significantly different from that of night-guards (P<0.01).ConclusionShift work manner influences sleep status of nurses and makes them having disturbances on falling sleep time, the time of sleeping, sleep efficiency and daytime function. But it doesn't need medication.

Objective To evaluate the clinical diagnostic value of nucleic acid amplification (TB- RNA),bacteriophage-based assay,3D culture and smear on the detection of Mycobacteria tuberculosis.Methods 291 clinical sample including 110 sputum,54 thoracic fluid,37 throat swab,31 bronchial fluid,13 cerebrospinal fluid,12 urine,8 lymph fluid and 20 others (pericardial effusion,feces, blood and abdominal fluid) and gynecological specimen (including 6 leucorrhoea and menstrual blood) were analyzed by these four methods.Results Among the 291 clinical samples,the positive rate of mycobacteria tuberculosis for TB-RNA,bacteriophage-based assay,3D culture and smear were 37.1%,28.9%,27.5% and 10.3%.The sensitivity and specificity of the TB-RNA,bacteriophage-based assay,3D culture and smear were 54.3% & 100%,41.7% & 88.9%,31.7% & 93.5% and 14.6% & 98.9%,respectively.Conclusions TB-RNA is an effective clinical diagnostic method for Mycobacteria tuberculosis.Although the sensitivity of smear is poorer than others,it is a universal testing method in clinical laboratory due to low cost.The positive rate of mycobacteria tuberculosis for 3D culture is lower than that of bacteriophage-based assay and TB-RNA.Although the time to result for 3D culture might last for few weeks,the isolates can be used for drug resistance screening and bacterial identification.
