Vascular cognitive impairment (VCI) is a large class syndrome caused by a variety of cerebrovascular diseases from mild cognitive impairment to dementia.In the VCI animal experiments,choosing a reliable test method is particularly important for evaluating animal cognitive function and the improving the quality of animal models.

Relative problems in the management of HIV antibody primary screening lab are discussed, including laborato-ry building, staffing and training, equipment management, document management, reagent management, quality control and security protection. It is pointed out that the standardized laboratory management is an important part of the HIV antibody primary screening lab's quality Control.

Chinese medicine and traditional health care are valuable cultural heritage in our country,it proves the theory and practice of the two all play an enormous role in the mankind's health for centuries,theories of the two all have a close connection.

Objective To study the electrochemical features of an improved enzyme bioelectrode for biofuel cell. Methods The enzyme electrode was prepared via biotin-avidin technology and its electrochemical features were explored. The conditions such as layers of enzyme films, strength of glucose, scan speed and temperature, which affected the electrochemical behavior of enzyme electrode, were studied. Results The results showed that the electrode had good electric current response to glucose. The enzyme electrode prepared can fulfill the need of biofuel cell and is a promising electrode to be used in human body.

Objective To investigate the indication, methods and therapeutic effects of breast-conserving surgery in mammary cancer of early stage. Methods A retrospective study on 28 cases of Ⅰ and Ⅱ stage of breast-conserving surgery was underwent. Results Breast-conserving surgery does not destroy the appearance symmetry of breast, and maintains a low baldness rate. The recurrence rate in 5 years after surgery is 5.3%, and the 5 years' survival rate is 100%. Conclusion Breast-conserving surgery combined with the hinese herbal medicine therapy is an effective and safe way to treat mammary cancer in a early stage.

A harmonious physician-patient relationship is closely correlated with hospital culture construction.This paper explores the correlation from the perspectives of roles in building up decent fame of hospitals,promoting the construction of medical ethics,cultivating a fine humanistic medical atmosphere,strengthening the social responsibility of hospitals,and further clarifies the important function of hospital culture construction in constructing a harmonious physician-patient relationship.

Human gene therapy needs to express exogenous DNA at the targeting cells,producing a practical and efficient therapeutic dosage at an approp-riate time(quantitative pharmacology)with a safe man-ner.Recombinant adeno-associated virus(rAAV)Vec-tom possess a number of properties and recent progress in rAAV production made it rapidly become the reagent of choice for therapeutic gene tmasfer.Over 60 clinical trials of gene therapy based on rAAV have been carried out.The dose response reaction between rAAV vectors and gene expression activity or clinical outcome is one of major aspects of these trials.Most studies showed that vector genomes(vg)and gene expression had a concentration-dependent relationship during a certain scope.However,gene expr~sion Can be afffected by viral serotypes,tissue tropisms,cell targeting,drug regulation,injection route,age and sex,etc.Thus,these aspects should be carefully comidered by scienti-sts,pharmacologisis and physicians during animal ex-periments or clinical trails.KEY WORDS gene therapy;viral vector;dose-re-sponse;quantitative pharmacology;clinical thempy

Objective To investigate the therapeutic effect of ginkgo-damole combined with prostaglandin E1 and explore its influences on clinical evaluation and hemorheology paramaters in treatment of diabetic patients with peripheral arterial disease(PAD). Methods 64 patients were randomly divided into two groups: the therapeutic group was given conventional therapy adding ginkgo-damole combined with prostaglandin E1, while the control group was given ginkgo-damole only. To compare ankle-brachial index(ABI) and hemorheology changes before and after the use of ginkgo-damole combined with prostaglandin E1 in diabetic patients with PAD. Result The total effective rate was 91.2% in therapeutic group, and the significant efficiency in therapeutic group was higher than that in control group ( 67.6% vs 36.7% ) ( P ＜ 0. 05 ). Compared with before the treatment , ABI increased significantly and hemorheological parameters improved significantly in two groups after the treatment( P ＜ 0. 05 or P ＜ 0. 01 ), and the difference were more significant in therapeutic group than in control group( P ＜ 0. 05 or P ＜ 0. 01 ). Conclusion Ginkgo-damole combined with prostaglandin E1 was effective and safe in treatment of diabetic patients with PAD.

Objective To determine the protein and mRNA levels ofinterleukin-17 (IL-17) and the proportion of Th17 cells in the peripheral blood of patients with systemic lupus erythematosus (SLE) and their clinical significance is analyzed. Methods Twenty-five hospitalized SLE patients were recruited and twentytwo healthy volunteers were enrolled as normal controls. Plasma protein and mRNA of IL-17 in the peripheral blood were measured by enzyme-linked immunosorbent assay and real time-PCR respectively. Flow cytometric assay was used to analyze the percentage of Th17 cells in SLE patients. The relationship between IL-17/Th17 cells and clinical or laboratory parameters of SLE patients was explored. Students' t-test and Spearman's correlation was used to evaluate the relationship between mRNA level and inflammatory parameters. Results The plasma concentration and mRNA level of IL-17 was significantly elevated in SLE patients as compared to the normal controls (P＜0.05). The percentage of Th17 cells in patients with SLE was higher than that of normal controls and was significantly increased in more active SLE patients and SLE with nephritis than less active SLE and SLE without nephritis (P＜0.05). Both plasma levels of IL-17 and the proportion of Th17 cells were positively correlated with SLEDAI (r=0.681, P＜0.01; r=0.426, P=0.034). Conclusion Plasma IL-17 protein and mRNA expression level and the percentage of Th17 cells in SLE patients are all significantly elevated and the close relationship between IL-17/Th17 cells and disease activity suggests that IL-17/Th17 may play an important role in the pathogenesis of SLE.
