Objective To investigate the current situation of healthcare-associated infection (HAI)management in basic level private medical institutions.Methods 118 basic level private medical institutions in a district of Chengdu were investigated through visiting and questionnaire.Results Of 118 medical institutions,only 2 had HAI manage-ment personnel,4 had HAI management system.22.03% had hand washing facilities in therapeutic rooms and con-sulting rooms,37.29% of institutions stored aseptic items in accordance with the requirements,55.93% of institu-tions disposed medical waste at disposal center;99.15% handled reusable items by users.Conclusion HAI manage-ment status is worried,health administrative department should strengthen support and supervision,especially in-tensified the supervision of private dental clinics.

After the research of PLA2R1 and its antibodies, Thrombospondin type-1 domain-containing 7A and its antibodies to membranous nephropathy (MN) has made a new understanding.Some researches have reported that the antibodies of PLA2R1 and THSD7A were mutually exclusive in MN, because THSD7A was found in PLA2R1-negative MN patients.But the latest researcher showed that these antibodies can be both positive in MN patients.Similar to the function of PLA2R1, THSD7A can assist clinical diagnosis, treatment, and monitor of MN.In contrast to PLA2R1, THSD7A was also highly expressed on both human and murine podocytes.We can use the mice model to study the pathogenesis of THSD7A-associated MN in the future.In this review, we describe the structure and function of Thrombospondin type-1 domain-containing 7A and its autoantibodies, highlight its role in MN and suggest possible aspects of its future clinical application.

Objective To investigate the effect of experimental benzolism on marrow eryghrocyte micromucleus.Methods Fifty male KunMingmice(KM)were randomly divided into 5 groups:one control group and four experimental groups with 10 mice in each group.The mice were injected subcutaneously with sodium chloride in control group and benzene in experimental groups on every Monday,Wednesday and Friday for four weeks.Four experimental groups were injected with a dosage of 0.5 ml/kg(group B1),1.0 nd/kg(group B2),1.5 ml/kg(group B3) and 2.0 ml/ks(group B4),respectively.Before and after injection of sodium chloride or benzene weekly.weight was measured,and the alteration of erythrocyte micronucleus in peripheral blood and marrow were detected.Results ① Compared to the control group,several indices were partly changed in B1 and B2 groups,while all indices changed significantly in group B3 and B4 groups four weeks after injection(P<0.01).②The erythrocyte micronucleus rate of experimental mice in peripheral blood and marrow showed ascending tendency with the extension of benzene injection phase,peak emerged in the third week and decreased in the fourth week.③In the 4th week,compared to the control group,the alteration of erythrocyte micronucleus in marrow in all experimental groups were significantly increaged(P<0.05).Conclusions Benzolism may induce the increasing of micronucleus rate of mature erythrocyte in peripheral blood and erythrocyte in marrow.which can be used to detect status of being restrained in marrow erythrocyte series.

OBJECTIVE:To determine plasma concentration of caffeine,dapsone and chlorzoxazone in rats,and to calculate pharmacokinetic parameters. METHODS:6 rats were given the mixture of caffeine,dapsone and chlorzoxazone intragastrically, 1.5,2 and 3 mg/kg,respectively. 0.2-0.3 ml blood were collected before medication and 0.5,1,2,3,4,6,8,12,24 h after medication.The plasma sample was treated with solid phase extraction. The plasma concentration of caffeine,dapsone and chlorzoxa-zone were determined by HPLC using N-(2-Hydroxyethyl) phthalimide as internal standard. The pharmacokinetic parameters were calculated using DAS 2.0 software. RESULTS:The linear ranges of caffeine,dapsone and chlorzoxazone were all 0.2-30 μg/ml (r were 0.996 4,0.996 1,0.998 8,respectively). The limit of quantitation were 0.2 μg/ml. The recoveries of low-concentration, medium-concentration and high concentration were(84.8±3.6)%-(111.4±10.2)%(RSD were 4.3%-9.8%,n=3),(107.0±13.3)%-(113.5±8.1)%(RSD were 7.1%-14.0%,n=3),(104.2±10.8)%-(111.1±12.2)%(RSD were 8.0%-11.0%,n=3). Pharmacoki-netic parameters were as follows as tmax(1.70±0.99),(1.50±1.00),(1.92±0.80)h;t1/2(0.73±0.22),(2.77±1.35),(2.78±2.34) h;cmax (2.60 ± 0.50),(5.78 ± 1.19),(9.76 ± 1.37) mg/L;AUC0-t (8.43 ± 0.79),(20.68 ± 1.91),(26.71 ± 2.45) mg·h/L(n=6). CONCLUSIONS:The method is simple,sensitive and accurate,and can be used for the plasma concentration determination and pharmacokinetic study of caffeine,dapson and chlorzoxazone.

In present paper,we studied three kinds of method of assay for IL-1:thymocyte proliferation assay;L_(?) cell proliferation assay and pyrogen assay.Stimultaneously we used ~(125)I-UdR in stead of ~3H-TdR.The results show that all of three kinds of method of assay for IL-1 can measure IL-1 activity of supernatants from cultured rat alveolar M? stimulated by LPS in vitro.It suggests that ~(125)I-UdR can incorporate into DNA synthesis of cell and mouse fibroblast cell line L_(?) can response to IL-1 of supernatant from cultured rat alveolar M? stimulated by LPS.

Objective To investigate the relationship among peroxisome proliferators - activated receptor gamma (PPAR-γ), pul-monary arterial systolic pressure(PASP) ,and insulin resistance in Chronic Obstructive Pulmonary Disease (COPD) patients. Methods A-mong 63 COPD patients, 30 patients with level of PASP above 40mmHg were enrolled in PAH group and other 33 patients were enrolled in COPD group. Twenty healthy medical examination subjects were enrolled in control group. The expression of PPAR-γ, mRNA was detected by real time fluorescent quantitative RT- PCR. Radioimmunoassay was used to measure the level of fasting plasma insulin (FIN). Fasting plas-ma glucose (FPG) was detected by glucose oxidase method. Results The expression of PPAR-γ mRNA was significantly decreased in PAH and COPD group, while FPG, FIN and IRI increased significantly. PAH group had more increased PASP, decreased expression of PPAR-γ and higher IRI than COPD group. Expression of PPAR-γ was negatively related to PASP and IRI. Conclusions The significantly down reg-ulated expression of PPAR-γ maybe explain the higher FPG and PASP.

Objective To discuss application of evidence-based nursing in nasopharyngeal carcinoma patients undergoing radiotherapy. Methods Evidence-based nursing was used in 33 nasopharyngeal carcinoma patients undergoing radiotherapy. Results After evidence-based nursing, all the patients actively cooperated with the doctors and nurses, lived through the treatment process smoothly, and radiotherapy complications were reduced or avoided. Conclusions Evidence-based nursing is an idealized nursing method which could reduce or avoid the complications and alleviate the pain of patients and improve the quality of nursing.

Aim of the present study is to investigate activation effect of nobiletin on cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel activity. CFTR-mediated iodide influx assay and patch-clamp tests were done on FRT cells stably co-transfected with human CFTR and EYFP/H148Q. Nobiletin potently activated CFTR chloride channel activity in a dose- and time-dependent manner. The CFTR blocker CFTR(inh)-172 could completely reverse the effect. Preliminary mechanism study indicated that nobiletin activated CFTR chloride channel through a direct binding way. In addition, ex vivo tests done on mice trachea showed that nobiletin time-dependently stimulated submucosal gland fluid secretion. Nobiletin may be a therapeutic lead compound in treating CFTR-related diseases including disseminated bronchiectasis.
