Objective To understand the utilization of antibiotics for acute upper respiratory infection through retrospectively analyzing the prescription in the outpatient department in a whole year,therefore to improve the rational drug using in primary healthy institutions.Methods Prescriptions from the outpatient department,Jan.2010 to Dec.2010 were managed in Excel software and the utilization was analyzed.Results In a total of 6101 prescriptions,2462(40.35％ ) were for upper respiratory infection.Of the 2462 prescriptions,1962(79.69％ )used antibiotics.The amount of prescriptions and the rate of antibiotics used were significantly higher than those for other infection diseases.Conclusion The investigation shows antibiotics abuse in primary healthy institution has become a severe problem.While the stuff in primary healthy institution are trained for some specific aims,the promotion should be spread to let doctors and patients know the danger of antibiotics abuse.

Mixed dyslipidemia is a common lipid disorder.Coadministrating hypolipidemic drugs for the treatment of mixed dyslipidemia has shown functions,such as enhancement of reaching lipid goals,reduction of side effects associated with increasing dosage.The usual combination is applied to add another agent on statins,including fibrates,niacin or ezetimibe.Special attention should be paid to the safety of such combination therapy.

Visual impairment is one of the common problems in the elderly,and regular screening should be considered for early detection as well as prevention.This article describes some of the common causes of vision loss in older adults,including cataracts,age-related macular degeneration,ametropia (presbyopia) and diabetic retinopathy.Patients with senile cataract should be offered a manifest refraction in the early stage,and surgical treatments are indicated when their vision is less than or equal to 0.4.Prevention and treatment of age-related macular degeneration may be achieved through medication or dietary adjustment.Vascular endothelial growth factor can be used in the treatment of neovascularage-related macular degeneration.Patients with presbyopia are advised to obtain a manifest refraction.Patients with diabetic retinopathy should be regularly offered an ocular fundus examination and receive early treatment when necessary,with particular attention paid to glycaemic control.

BACKGROUND:Studies have shown that theβ-tricalcium phosphate can be combined with other macromolecular compounds to improve the mechanical strength and histocompatibility, meeting the requirements of clinical application. ＜br> OBJECTIVE:To evaluate the selection and preparation methods of composite scaffold in bone tissue engineering, and to describe the problems we are facing. ＜br> METHODS:The first author retrieved PubMed, Google Scholar, CNKI, Wanfang, and VIP databases by computer using the keywords of“β-tricalcium phosphate,β-TCP, PLGA, PLA, scaffold, prepare”in English and Chinese, respectively. ＜br> RESULTS AND CONCLUSION:β-tricalcium phosphate combined with polylactic acid-glycolic acid/polylactic acid as bone tissue engineering scaffolds has achieved a great progress. At present, the organic polymer composite scaffolds can be prepared by microsphere sintering, fiber bonding, solvent casting/particulate leaching, emulsification/freeze drying technology, gas foaming method, phase separation technology, rapid prototyping technology and electrostatic spinning method.β-tricalcium phosphate composite scaffolds with polylactic acid-glycolic acid/polylactic acid can be customizable so as to meet different requirements for bone tissue engineering, which can improve the porosity, mechanical properties and biodegradation by improving fabrication techniques and processings, ratio of raw materials and fil er proportion.

With the development of holistic nursing care and the deepening study of nursing management,it is necessary for us to introduce related ethical principles into nursing management.The most important ethic principles that should comply with nursing management include humanism principle,justice principle and harmony principle.

This article collects data of nursing staff from 34 hospitals in Shanghai by on-spot interview which could reflects the current situation of nursing human resource allocation there.The result shows a shortage of nurse staff'.Most of them are female and youthful,with lower diploma and lower job title.By analyzing the equity of allocation,the accessibility of health service and the rationality of staff structure,we give some advices that the government should allocate the nursing human resource rationally to insure the quality of nursing care and maintain the stableness of nursing staff team.

To study the efficacy of small dosage of simvastatin on the treatment of hyperlipidemia, and the effect of polymorphisms in ApoB gene expression. Sixty one patients with hyperlipidemia were selected and simvastatin 5mg/d was used. TC, TG, HDL, LDL, ApoAI and ApoB and the function of liver and kidney were measured in every patient prior to the treatment and 4, 8, 12 weeks after treatment. RFLPs was applied for determination of polymorphisms on Xbal locus of the ApoB gene. In the total of 61 patients, X + X - genotype was found in 5 patients (8.20%), and X - X - genotype in 56 patients (91.80%), but no X + X + genotype was found. The relative frequency of X + allele was 0.041, and X - allele was 0.959, suggesting X - allele was still a dominant one in the patients with hyperlipidemia. The results showed that small dosage of simvastatin could effectively reduce blood levels of TC, TG, LDL C and ApoB. The levels of TC and LDL C lowering was more prominent in X - X - genotype than that in X + X - genotype (27.62% and 35.02% vs. 22.36% and 20.05%, P

MicroRNA (miRNA) is a small non-coding RNA that contains 21 to 23 nucleotides and can down-regulate gene expression by translational repression. Recent studies found that some miRNAs might function both as oncogenes and tumor suppressors; its role in the tumorigenesis may complement and enrich the mechanisms of tumorigenesis. Liver cancer is a great threat to human health, whose pathogenesis is still not completely understood. MiRNAs can influence the tumorigenesis, differentiation and treatment of liver cancer. Here we summarizes the related progression in research of miRNA and liver cancer.

Systemic lupus erythematosus(SLE)is an autoimmune disease that affects primarily women,commonly in their reproductive years but does not influence fertility.More recent prospective studies indicate that pregnancy is safe for the majority of mothers if it is planned when SLE is quiescent.In pregnant women with lupus nephritis,the outcome of the fetal and maternal is strongly correlated with lupus activity,kidney function and the presence of aPL at the time of conception.To prevent renal complications,prednisone is given after conception,and reinforcement for a few days before the estimated delivery and for a week after delivery or miscarriage with rapid tapering to maintenance levels may be suggested.Treatment of flares includes corticosteroids,hydroxychloroquine,azothioprine and cyclosporin A.Blood pressure is controlled with methyldopa,labetalol nifedipine or hydralazine.

: In recent years, more attention has been attracted by non-invasive measurement of the arterial elasticity function. Pulse wave velocity (PWV) assay is one of the commonly used Methods . The PWV measured on different sites of the artery system indicates the elasticity characteristics of the arterial segment and may have different pathophysiology bases and clinical significance.
