OBJECTIVE:To evaluate the lipid-regulatory efficacy and safety of rosuvastatin (10 mg?d-1) for Chinese population. METHODS: The pertinent literature comparing the serum blood lipid level before and after treatment with rosuvastatin (10 mg?d-1) between 2001 and 2008 were collected by retrieving Wanfang database,CNKI,Weipu electronic periodicals;and the data were given a meta-analysis using RevMan 4.2 software,meanwhile the safety of rosuvastatin was evaluated. RESULTS: A total of 346 patients were enrolled in 5 trials. After treatment with rosuvastatin (10 mg?d-1),the low density lipoproteincholesterol(LDL-C) was lowered by 1.71 mmol?L-1 on average;the total cholesterol (TC) was lowered by 1.98 mmol?L-1 on average;high density lipoprotein cholesterol(HDL-C) was increased by 0.17 mmol?L-1 on average;and the level of triglyeride was lowered by 0.79 mmol?L-1 on average. A total of 54 adverse events were reported,and the adverse drug reactions manifested chiefly as upper respiratory infection,mild notalgia,debilitation and gastrointestinal upset. No severe side effects were reported. CONCLUSION: It has been confirmed by domestic clinical trials that rosuvastatin(10 mg?d-1) is safe and effective for Chinese population.

Objective:To investigate the use of antibacterial drugs during the perioperative period of a cesarean section and observe the differences before and after antibacterial drug remediation. Methods:1 569 cesarean cases from 2010 to 2012 were investigated, and the use of antibacterial drugs, drug categories, drug combinations, medical expenses, and so on was statistically analyzed with the use of the statistical software SPSS13. 0. Results:The rate of antibacterial drug usage within the 1 569 cesarean cases was 100%;for pre-operative antibacterial drug remediation, azithromycin, cefathiamidine, and ornidazole were the top three, while the top three antibacterial drugs for post-oper-ative remediation were arecefathiamidine, cefuroxime, and clindamycin. There was no significant difference between the two groups of incision infections, and the rate for combined use of drugs dropped. The analysis of drug costs is of statistical significance. Conclusion:The analysis of antibacterial drug remediation is useful for the rational use of anti-bacterial drugs and a reduction of costs.

Objective To observe the long-term visual quality and clinical effect of aspheric diffractive multifocal intraocular lens (IOL) implantation for congenital and developmental cataracts in childhood.Methods A retrospective cohort study on multifocal IOL implantation for congenital and developmental cataracts in childhood (aged 8 to 14 years) was performed in the First Affiliated Hospital of Zhengzhou University from August 2013 to January 2015.The clinical data of 67 eyes from 46 congenital cataract patients who received phacoemulsification with IOL implantation were collected.The AMO (ZMB00) IOL was implanted in 34 eyes of 24 patients in the multifocal IOL group,and Bausch & Lomb (MI60) IOL was implanted in 33 eyes of 22 patients in the monofocal IOL group.The distance,intermediate and near vision acuity were analyzed in 3,6 and 12 months after surgery,including uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA).The wavefront aberrations,modulation transfer functions (MTF) and stereopsis were obtained with iTrace Analysis System,Optec-6500 Visual Functional Analyzer and Titmus Stereo Test Chart,respectively in 12 months after surgery.The near additional degree,removing glasses rate and myopic shift were compared between the two groups in postoperative 12 months.Results The intermediate and near UCVA in the multifocal IOL group were obviously better than those in the monofocal IOL group 3,6 and 12 months after surgery (intermediate:Z=-3.74,-4.36,-3.66;all at P=0.00.near:Z=-2.67,-2.50,-2.33;all at P＜0.05).There were no significant differences between the two groups in total aberration,high and low order total aberrations,comatic aberration,trefoil aberration,spherical aberration and secondary astigmatism under the 5.0 mm optical zone in 12 months after surgery (all at P＞0.05).The MTFs under the 5.0 mm optical zone and 5,10,15,20,25,30 c/d in the multifocal IOL group were insignificantly lower than those in the monofocal IOL group (all at P＞0.05).In addition,the near stereopsis,near additional degree and myopic shift (AD) were reduced in the multifocal IOL group compared with monofocal IOL group (both at P＜0.05).The glasses removing rate was 93.3％ in the multifocal IOL group,which was significantly higher than 33.3％ in the monofocal IOL group (x2 =23.25,P =0.00).No significant difference in the incidence of posterior capsular opacification was found between the two groups (P＞0.05).The myopic shifting rates were 16.7％ and 83.3％ in the multifocal IOL group and monofocal IOL group,with a significant difference between the two groups (x2=15.02,P=0.00).Conclusions The aspheric multifical IOL implantation can achieve good and stable distance,intermediate and near visual acuities,provide better near stereopsis,reduce postoperative dependence on spectacles and decrease the incidence of myopic shift in child cataract patients.

Post-stroke depression (PSD) is one of the common complications of stroke, which can seriously affect the functional rehabilitation of patients with stroke and increase their mortality and disability rate. As for the pathogenesis of PSD, endogenous theory emphasizes that it is closely associated with biological mechanism, while reactive theory believes that it is associated with psychosocial factors. At present, the research on the pathogenesis and treatment of PSD focuses on inflammation, immune response, stress, nerve regeneration, brain network, biological rhythm disorder, sleep disorder, melatonin and so on. This article reviews the research progress on the neurobiological mechanism of PSD and the related treatment for the pathogenesis.

Objective Establishment and evaluation of a mouse model of aldosterone-induced multi-organ damage.Methods Twenty mice were randomly divided into four groups,with five mice in each group:a blank control group(0 μg/(kg·d)),a low-dose aldosterone group(150 μg/(kg·d))),a medium-dose aldosterone group(300 μg/(kg d)),and a high-dose aldosterone group(450 pug/(kg·d)).Aldosterone-containing osmotic minipumps were surgically implanted under the skin,and aldosterone was infused for 4 weeks to establish the aldosterone-induced damage model.The body weight and blood pressure of the mice were recorded weekly.After the 4 week modeling period,the mice were euthanized,and their tissues were collected for observation and analysis of blood pressure and histological morphology of various organs.Results(1)After 4 weeks of aldosterone infusion,the serum aldosterone levels were significantly increased in the medium-dose and high-dose aldosterone groups,but not in the low-dose aldosterone group.(2)After the implantation of osmotic minipumps,the systolic blood pressure was significantly increased in the low-dose,medium-dose,and high-dose aldosterone groups during the second and third weeks,but decreased in all these groups during the fourth week.(3)The kidney and heart in the low-dose,medium-dose,and high-dose aldosterone groups showed varying degrees of damage,interstitial edema,collagen deposition,and fibrotic lesions.The liver in the low-dose aldosterone group showed a small amount of collagen deposition,while the medium-dose and high-dose aldosterone groups showed varying degrees of hepatocyte damage,collagen deposition,and fibrotic lesions.Conclusions Aldosterone can induce multi-organ damage in mice.Under this modeling method,organ damage is mainly manifested as edema,collagen deposition,and fibrotic lesions.
