OBJECTIVETo establish fluorescent quantitative PCR method for detecting human herpes virus type 6 (HHV6).

METHODSAccording to the specific sequence of human herpes virus type 6 genes, the primers and the fluorescent probe (TaqMan) were designed and synthesized. The fragment generated from HHV 6 gene as template was cloned into the pMD18-T vector which was constructed from the pUC 18. And the positive recombinant plasmid was 1:10 diluted and used as standard quantitative template to make the standard curve for sample detection.

RESULTSThe standard curve indicated the linear relationship between Ct (cycle threshold) and template concentration. The clinical samples from 135 cases were detected by this system, 16 cases among 135 were positive.

CONCLUSIONThe fluorescent quantitative PCR method for the detection of human herpes virus type 6 is simple and accurate, and this method may be helpful to clinical diagnosis.

BACKGROUNDDyslipidemia, a well-known risk factor for cardiovascular disease, is common in patients with kidney disease. Recent studies discerned that dyslipidemias play a critical role in renal damage progression in renal diseases, but the association between dyslipidemias and chronic kidney disease (CKD) in the general population remains unknown. Thus, we assessed whether the growing prevalence of dyslipidemia could increase the risk of CKD.

METHODSA total of 4779 middle-aged and elderly participants participated in this study. Dyslipidemias were defined by the 2007 Guidelines in Chinese Adults. Incident CKD was defined as albuminuria and/or reduced estimated glomerular filtration rate (eGFR, < 60 ml×min(-1)×1.73 m(-2)). Regression analysis was used to evaluate the association between dyslipidemia and albuminuria/reduced eGFR.

RESULTSParticipants with hypercholesterolemia exhibited a greater prevalence of albuminuria and reduced eGFR (10.0% vs. 6.1%, P = 0.001; 4.0% vs. 2.4%, P = 0.028, respectively). Both hypercholesterolemia and low high density lipoprotein cholesterol (HDL-C) were independently associated with albuminuria (odds ratio (OR) 1.49; 95% confidence interval (CI) 1.08 - 2.07 and OR 1.53; 95%CI 1.13 - 2.09, respectively). The multivariable adjusted OR of reduced eGFR in participants with hypercholesterolemia was 1.65 (95%CI 1.03 - 2.65). As the number of dyslipidemia components increased, so did the OR of CKD: 0.87 (95%CI 0.65 - 1.15), 1.29 (95%CI, 0.83 - 2.01), and 7.87 (95%CI, 3.75 - 16.50) for albuminuria, and 0.38 (95%CI 0.21 - 0.69), 1.92 (95%CI 1.14 - 3.25), and 5.85 (95%CI 2.36 - 14.51) for reduced eGFR, respectively.

CONCLUSIONSOur findings indicate that dyslipidemias increase the risk of CKD in the middle-aged and elderly Chinese population. Hypercholesterolemia plays an important role in reducing total eGFR. Both low HDL-C and hypercholesterolemia are associated with an increased risk for albuminuria.

OBJECTIVETo probe into a treatment method for increasing clinical therapeutic effect on xerophthalmia.

METHODSForty-five cases were randomly divided into acupuncture group 1, acupuncture group 2 and control group. The acupuncture group 1 were treated with acupuncture based on syndrome types, and the acupuncture group 2 with acupuncture at local acupoints, and the control group with dripping of artificial tears. Local symptoms of eyes, S1T, BUT and FL were observed before and after treatment.

RESULTSS1T and BUT increased after treatment in the two groups (P < 0.01, P < 0.05), but did not significantly change in the control group (P > 0.05). There were significant differences in change of FL as the control group compared with the acupuncture group 1 and 2. The total effective rate was 86.7%, 66.7% and 33.3% in the acupuncture group 1, 2 and the control group, respectively.

CONCLUSIONThe integral syndrome differentiation acupuncture can improve secretion of tear, increase stability of tear film, improve local symptoms of eyes with a therapeutic effect better than acupuncture at local acupoints and artificial tears.

Objective: To understand the effect of dobutamine on the integrated backscatter of myocardium. Methods: Nineteen open-chest dogs were detected by HP Sonos 5500 with S8 transducer, and the WT, AIBS and CVIB were measured before and after the dobutamine stress. Results: During the dobutamine stress, following the increase of WT, the transmural, subepicardial and subendocardial CVIB all increased. And the increase of subepicardial CVIB was greater than that of subendocardial CVIB, leading to the decrease of TGI. But the AIBS didn't change significantly in the whole process. Conclusion: Dobutamine can enhance myocardium CVIB but has no obvious infleunce on AIBS.

Objective:To discuss application effect of risk management in medical device management of hospital and its impact on management quality.Methods:9800 medical devices of hospital were selected and divided into routine management group (the corresponding medical devices came from the term of 2014 year to 2015 year, n=4900) and risk management group (the corresponding medical devices came from the term of 2014 year to 2015 year, n=4900) according to different management method.The arrangement and placement of device, the specification and quantity of device, the placement of accessories and the intact situation of widgets of the two groups were recorded and calculated as statistics method.A self-designed questionnaire was adopted to assess these situations included classification error, incompetence, loss of device, undersupply, instrument damage, the timeliness degree of supply, the timeliness degree of withdrawing and quality of packaging in the management process for medical devices.And the management effects of two groups and the corresponding influences of them for curative effect were further compared.Results:The arrangement and placement of medical device, the different specification and quantity of device, the placement of accessories, intact rate of widgets of risk management group were significantly higher than those of■timeliness degree of supply, the timeliness degree of withdrawing and quality of packaging of risk management group post management were significantly higher than those of routine group (t=20.394, t=21.847, t=16.481, P<0.05) .Conclusion:The effect of risk management that is used in medical equipment management of hospital is significant, and it contribute to improve the management quality for medical apparatus and instruments and reduce the error rate of instruments, and it can ensure the safety usage of them in hospital.
