Objectives To learn the bednet use and influential factors among Wa and Lahu ethnics,and further to explore feasible ways of promoting the use of bednets and insecticide-treated nets (ITNs). Methods Questionnaire surveys and statistical analysis with EpiInfo 2000 software package were carried out. Results Only did 2.8% [95% confidence intervals(95%CI):1.2%-5.4%] of Wa and 4.8 % (95%CI:2.8%-8.1%) of Lahu ethnic members use bednets frequently or sometimes. Bednets were not available for 67.7% (95% CI:62.0%-73.1%) of Wa and 59.7% (95% CI:53.1%- 66.1%) of Lahu ethnic peoples. Most people who had bednets did not often use them for anti-mosquitoes. Results of multivariate logistic regression confirmed significant correlation between bednet use and knowledge of malaria prevention. Conclusion The coverage and use rates are very low in the two ethnical minorities. Health education, communication and social marketing are the strategies for promoting the usage of bednet and ITNs.

Objective To investigate the inhibitory effect of Rhodiola total flavonoids on transforming growth factor (TGF)-β1-induced proliferation of cardiac fibroblasts (CFB) in the rats, and to explore its mechanisms of improving myocardial fibrosis.Methods 5 μg·L-1 TGF-β1 was used to induce the proliferation of CFB to build the cell models of myocardial fibrosis.The cultured CFB were divided into control group,model group,and low, medium,high doses (25,50 and 100 mg· L-1 )of Rhodiola total flavonoids groups.The cells were treated for 48 h,the vitalities of cells were detected by MTT,the levels of collagen proteinⅠ (ColⅠ)and collagen proteinⅢ(Col Ⅲ)in supernatant were measured by ELISA,and the activities of total superoxide dismutase (T-SOD)and glutathione peroxidase (GSH-Px)were detected,the levels of malondialdehyde (MDA)and glutathione (GSH) were also measured.Results The MTT results indicated that compared with control group,the cell vitality in model group was significantly increased (P < 0.01 ).compared with model group,the cell vitalities of CFB in Rhodiola total flavonoids groups were significantly decreased (P < 0.05 ). Compared with control group, the T-SOD activity in model group was decreased, while the MDA level was significantly increased (P <0.05);compared with model group,the T-SOD activities in 50 and 100 mg· L-1 Rhodiola total flavonoids groups were increased (P <0.01);the MDA levels in 25 and 50 mg· L-1 groups were decreased significantly (P < 0.05). Compared with control group,the GSH-Px activity and GSH level in model group were significantly decreased (P <0.01).Compared with model group,the GSH-Px activities and GSH levels in Rhodiola total flavonoids groups were increased (P <0.05).Compared with control group,the ColⅠand Col Ⅲ levels in model group were significantly increased (P <0.01);compared with model group,the ColⅠand Col Ⅲ levels in Rhodiola total flavonoids groups were significantly decreased (P <0.05).Conclusion Rhodiola total flavonoids can inhibit the proliferation of rat CFB.The development of myocardial fibrosis may be inhibited by Rhodiola total flavonoids through anti-oxidative stress pathway.

OBJECTIVE:To investigate the situation of pharmacoeconomic researches about lipid-lowering drugs in China, and to seek the regimen with good cost-effectiveness in order to provide reference for rational drug use in the clinic. METHODS:Retrieved from CNKI and Wanfang database,pharmacoeconomic literatures about lipid-lowering drugs,published in domestic jour-nals during 2011-2015,were included to discuss the problems of pharmacoeconomic researches about lipid-lowering drugs and put forward related suggestions. RESULTS:Rosuvastatin and other medicines showed good cost-effectiveness,while there were many problems of domestic published pharmacoeconomic researches about lipid-lowering drugs,such as different research methods,dif-ferent treatment courses,different methods of cost calculation,single effect index and absence of ADR. On the whole,the research-es were low in quality,which led the difficulty of accurately obtaining the drugs with best cost-effectiveness. CONCLUSIONS:In the future,related researches should confirm research duration and health output index,effect index and evaluation method accord-ing to disease types and research objectives;enhance the unity of research and design methods;pay attention to cost discount;in addition,strengthen pharmacoeconomic researches about lipid-lowering TCM and compare it with chemical drugs.

Objective:To explore the effect of tectorigenin on myocardial fibrosis(MF) in the rats and clarify the related mechanism,and to provide reference for its clinical application. Methods:Sixty Wistar rats were randomly divided into normal control group,model group,positive drug (capropril) control group, and low,middle,high doses of tectorigenin groups(n=10).Except normal control group, the rats in other groups were used to construct MF models by subcutaneous injection of 5 mg·kg -1·d -1 isoproterenol (Iso) for 7 d.The rats in tectorigenin groups and captopril group were intragastricly administrated with different doses of tectorigenin (25,50,100 mg·kg-1·d-1)and captopril(10 mg·kg -1·d -1) from the second day after modeling for consecutive 28 d.Bl-420E+ biological function experiment system was used to detect the heart function;Heart mass index (HMI) and left ventricular mass index (LVMI) were measured after experiment.UV detection was used to measure the levels of malondialdehyde (MDA) and the activities of superoxide dismutase (SOD) in myocardial tissue.Microplate reader was used to measure the activities of lactic dehydrogenase(LDH) and creatine kinase(CK) and the levels of nitric oxide (NO)in serum.ELISA were used to detect the levels of collagen typeⅠ(ColⅠ) and collagen type Ⅲ (Col Ⅲ) in myocardium tissue of the rats.The pathological changes of myocardium tissue of the rats in various groups were observed by HE staining.Results:Compared with normal control group,the HR of rats in model groups was increased,and the left ventricular systolic pressure (LVSP) was decreased(P<0.01);the HMI and LVMI were increased(P<0.05),the levels of MDA in left ventricular myocardial tissue was increased(P<0.01),and the activity of SOD was decreased,the levels of serum ColⅠ,Col Ⅲ and the activities of LDH , CK were also increased(P<0.01);the level of NO in serum was decreased(P<0.01).Compared with model groups, the HR were decreased,LVSP were increased, and HMI and LVMI of the rats in different doses of tectorigenin groups were decreased in a dose-dependent manner;the levels of MDA were reduced;the activities of SOD were increased in myocardium tissue,and the CK activities and the ColⅠ and ColⅢ levels were decreased(P<0.05 or P<0.01);the LDH activities in middle and high doses of tectorgenin groups were decreased(P<0.01);and the levels of NO in serum in different doses of tectorigenin groups were significantly increased(P<0.05 or P<0.01) .Conclusion:Tectorigenin could inhibit the MF induced by Iso in the rats, and its mechanism may be related to antioxidation,scavenging free radical and inhibition of collagen synthesis.

Objective To explore the therapeutic value and effects of relaxing retinotomy for perforating traction retinal detachment(PTRD). Method A retrospective survey was done in 21 patinets (21 eyes) with PTRD who underwent vitrectomy combined with relaxing retinotomy in our hospital from 1998 to 2001. Results The retinae were completely reattached in all 21 cases. The visual acuity of 12 patients (57%) was counting finger, and the best visual acuity was 0.05. Among the 18 patients who were followed up for 6 to 25 months, 14(77.8%) remained retinal reattachment. Conclusions Relaxing retinotomy is effective for anatomic reattachment of PTRD, especially to the patients with retinal incarceration and severe proliferative vitreoretinopathy.
