1.The Empirical Research of the Impact of Health Insurance on Consumption for Urban and Rural Households
Chinese Health Economics 2013;(10):5-7
Objective: To explore the effect of health insurance on consumption for rural and urban households. Methods: Using empirical study with the method of quasi-social experiment. Results: Households with health insurance have more consumption than those without health insurance. The higher the coverage of family health insurance improves, the more effects medical insurance would encourage family consumption. Meanwhile, the marginal effect of health insurance on rural households ’ consumption is much bigger than that of urban households. Conclusion: Through enhancing households’ risk tolerance, health insurance reduces households’ precautionary saving motivation and impels to increase the current consumption.
2.The effects of short-term high-dose statins on the prevention of contrast-induced nephropathy in patients undertaking coronary angiography: a systematic review and meta-analysis
Chinese Journal of Internal Medicine 2011;50(11):942-946
ObjectiveTo assess the effects of short-term (2-7 d) high-dose (80 mg/d) statins in the prevention of contrast-induced nephropathy ( CIN).MethodsWe searched PubMed, Embase,ScienceDirect,Scopus,Ovid andWileyInterScience with the key wordsof “ statins/statin/HMG-CoA reductaseinhibitor” ,“contrast ” and“ nephropathy/nephrosis/nephrotoxicity/kidneyfailure”inall languages from 1996 t0 2010 for RCT that assessed the preventive effect of short-term (2-7 d)high-dose( 80 mg/d) statins on CIN.ResultsFive trials with a total of 1009 patients were identifiedTwo studies were conducted in patients with CKD 3-5 stages ( GFR≤60 ml/min or serum creatinine≥97.2 μmol/L) and the remaining 3 studies were conducted in patients with CKD l and 2 stages.Analysis of the data in patients with CKD 3-5 stages did not reveal a statistically significant difference in CIN incidence between the statins and placebo groups (6.50%vs 7.2% ).The relative risk ( RR)was 0.89 without evidence of heterogeneity (12 =Oqo,P=O.79).Analysis of the data in patients with CKD I and 2 stages revealed a significantly lower CIN incidence in the statins group( 3.60-/o )than that in the placebo group( 11.9% ).The RR was 0.28 without evidence of heterogeneity( I2=0%, P =0.87 ). Conclusion Short-termhigh-dosestatins treatment may be benefical in reducing the incidence of CIN in patients with CKD l and 2 stages,while nobenefit has been shown in the patients with CKD 3-5 stages.

Chinese Journal of Nephrology 2012;(10):775-779
Objective To explore the role of hemoglobin (Hb) level in mortality and morbidity of chronic kidney disease (CKD)patients,aiming to give some evidence for therapy of anemia.Methods Randomized,clinical trials (RCTs) were identified by searching Medline,Embase and the Cochrane library.All the analyses were performed using the Revman software available free from the Cochrane collaboration.Results Twenty-three trials involving 10 204 patients were identified.Overall,the high Hb target was associated with increased risk of all-cause mortality (RR=1.10,95% CI 1.00 to 1.21),hypertension (RR=1.40,95% CI 1.12 to 1.75),stroke and hospitalization (RR=1.07,95% CI 1.00 to 1.14) compared with low Hb target (P<0.05).No significant difference was found in the risks of non-fatal mycardial infarction (RR=1.13,95% CI 0.79 to 1.62) and renal replacement therapy (RR =1.00,95% CI 0.85 to 1.18).Conclusions Targeting low Hb target is beneficial to CKD patients based on reduced risk of hypertension,hospitalization,stroke and all-cause mortality.However,no significant difference is found in non-fatal mycardial infarction and renal replacement therapy.
7.Quantitative changes of anterior segment before and after implantable collamer lens implantation for high myopia with Pentacam anterior segment system
International Eye Science 2015;(5):789-792
?AlM: To analyze the quantitative changes of anterior segment by Pentacam anterior segment system and to evaluate the safety and effectiveness after implantable collamer lens ( lCL) implantation for high myopia.
?METHODS:Twenty- one patients with 39 eyes were implanted lCL in our hospital from September 2011 to February 2013. The follow-up was 6 ~ 12mo. Central anterior chamber depth ( ACD ) , anterior chamber angle ( ACA) , anterior chamber volume ( ACV) were measured by Pentacam preoperatively, 1wk, 1 and 6mo postoperatively. The distance between crystal lens and lOL ( lCL- vault ) were measured at 1wk, 1 and 6mo postoperatively. Preoperative uncollected visual activity ( pre - UCVA ) , best corrected visual acuity ( BCVA ) , postoperative uncorrected visual acuity ( post-UCVA) and intraocular pressure ( lOP) were recorded. The paired t-test was used to access the data preoperatively and postoperatively in the statistical way by using SPSS 18. 0 statistical software.
? RESULTS: Preoperatively, at 1wk, 1 and 6mo postoperatively, ACD were 3. 27±0. 22, 3. 02±0. 33, 2. 98±0. 31, and 2. 98±0. 32mm. ACA were (40. 39±5. 40)o, (26. 70±4. 47)o, (26. 96±4. 48)o, and (26. 95±4. 45)o. ACV were 207. 74±25. 43, 122. 87±17. 58, 128. 05±17. 84, and 128. 64±17. 50mm3 , respectively. There were statistically significant differences between preoperative and postoperative data in ACD, ACA, ACV (P<0. 05). The distances between crystal lens and lOL ( lCL-vault) were 0. 49±0. 13, 0. 46±0. 13, and 0. 46±0. 14 at 1wk, 1 and 6mo postoperatively. There were statistically significant difference between 1wk and the others (P<0. 05). There were statistically significant different between the preoperative BCVA and postoperative BCVA(P<0. 05). There was no contact between lOL and the crystal len. The anterior chamber angle was all open. There were no serious complications such as cataract, glaucoma, cystoid macular edema, retinal detachment, etc.
?CONCLUSlON:ACD, ACA, ACV by Pentacam anterior segment system are found to be decreased after the operation, but there is still a relative safe distance between lOL and the crystal len. lCL implantation is a safe, efficacy method in correcting high myopia, but the long-term effects will require further observation.
