Objective:To measure the concentration of free fatty acids(FFAs) and analyse its associations with correlative factors in patients with polycystic ovarian syndrome(PCOS).Methods:11 obese and 28 non-obese women with PCOS and 21 age-matched healthy women were recruited.Serum concentration of FFAs,free testosterone,androstenedione,total testosterone,sex hormone binding globulin,TC,TG,HDL-c,LDL-c,fasting plasma glucose (FPG),2-hours post prandial glucose (PPG),fasting insulin(FINS) and insulin sensitivity (with two-step hyperinsulinemic euglycemic clamp technique) were measured.Results:There was no significant difference in serum FFAs level between obese and non-obese women with PCOS,while both groups showed higher serum concentration of FFAs than controls( P

In post-trial follow-up of DCCT,UKPDS and Steno-2 studies,sustained beneficial effects on the risk reductions for microvascular and macrovascular complications has been observed in previous intensive treatment group,suggesting that patients with diabetes benefit mostly from early intensive blood glucose control.On the other hand,intensive glucose lowering therapy has been shown to increase the risk of all cause mortality in high-risk patients with type 2 diabetes in ACCORD study.Therefore,the target of blood glucose control should be individualized for each diabetic patient.Not only intensive glucose lowering therapy but also avoidance of hypoglycemia during therapy should be highly considered.

It is of great importance to have a correct understanding of what is meant by governmental purchasiug and the system of governmental purchasing. The authors first expound the connotation and extension, characteristics and forms of governmental purchasing and the significance and necessity of centralized drug purchasing. Then they focus their discussion on the specific procedures of centralized drug purchasing. Finally they point out that it is imperative to seek unity of thinking, standardize operations, adopt institutionalized means of management, and make a really good job of centralized drug purchasing.

The recent development of process analytical chemistry(PAC) in the past years is reviewed. The content includes process measurement, sensor, chemometrics etc. The future of PAC is also discussed. 62 references are cited

Respirator is one of medical equipment in the first-aid, the clinical risk of it is much higher than the general medical equipment and diagnostic or patient monitor equipment. As a result, the quality control of it is particularly important. Several issues of the quality control of the respirator, such as the pre -purchase technical feasibility study, acceptance and installation after arrival, respirator use and management, respirator-reported loss demonstration and cost- benefit analysis of it are discussed from the angle of clinical engineers and technical personnel.

Objective To investigate the epidemiologic features of infant rotavirus (RV) diarrhea in Nanjing area .Methods The detection of group A rotavirus were performed on 7 325 outpatients from intestinal clinic of Nanjing Children′s Hospital by using immune colloidal gold method ,and the epidemiological analysis were did according to the detection results .Results In the 7 325 pa-tients ,2 353 were found rotavirus positive ,the total positive rate was 32 .12% .The positive rate of 1 -2 years old group was the highest(43 .51% ) ,compared with other age groups (P< 0 .05) .In November ,December and January ,the positive rates were 52 .20% ,46 .98% ,46 .59% ,respectively .Compared with the positive rate in other months ,there was statistically significant differ-ence(P<0 .05) .The infection rate of RV in vaccine group and non-vaccine group were 9 .06% and 38 .74% ,respectively .There was significant difference between the two groups .Conclusion Infants of 6 months to less than 3 years old in Nanjing have higher de-tection rate of RV infection ,and the infection peak appears in autumn and winter .

BACKGROUND:Sustained-release carriers of insulin shaped as microspheres made of different biomaterials have become an issue of concern. OBJECTIVE:To summarize the carrier materials and methods to prepare sustained-release microspheres of insulin. METHODS:Wanfang and PubMed databases were retrieved by computer for articles related to sustained-release carriers of insulin published from 1997 to 2015. The search terms were“insulin, control ed-release carrier, biomaterials”in Chinese and English, respectively. RESULTS AND CONCLUSION:Natural biodegradable polymer materials are preferred to prepare sustained-release microspheres of insulin, including gelatin, alginate, chitosan and its derivatives. These natural materials have good biocompatibility, degradability, film-forming and microsphere-forming abilities. Synthetic biodegradable polymer materials as carrier materials can promote drug stability and effective utilization, and realize targeted drug delivery. According to different physicochemical properties of materials, sustained-release carriers of insulin that meet different requirements can be prepared using emulsion-chemical crosslinking, spray drying and solvent evaporation methods. This review provides new insight into the development of stable drug carriers.

MicroRNA,which is found in recent years,is a class of small noncoding RNAs of about 18-24 nucleotides in length,that can regulate gene expression.It induces mRNA degradation or inhibit translation of tagert genes mainly by complete or incomplete base pairing to the 3' untranslated region of tagert messenger RNAs.The application of microRNA biology technology provides new methods to the research of multiple diseases,and can further elucidate its occurrence,development mechanism.In this paper,microRNA biology-related researches are introduced and miR-125 in a variety of diseases is reviewed.
