Objective To explore the effects of dexamethasone on ovulation induction in polycystic ovary syndrome (PCOS).Methods This clinical study included 68 women with PCOS, which of them were divided into two groups: 34 in dexamethasone treating(dexamethasone combined with ovulation induction) and 34 in con-trol(ovulation induction treatment only).Subsequently, comparisons were made between pre and after drug treat-ment in two groups, the main indexes were the levels of testosterone(T), luteinizing hormone(LH), follicle stim-ulating hormone(FSH), growth rate of follicle, and body mass index(BMI).And we have also considered the o-vulation rate and pregnancy rate, and compared these indexes in dexamethasone treating group with control group.Results There were significant differences between pre and after dexamethasone treatment in the levels of T in treatment group(P < 0.01), and there were not significant differences between pre and after treatment in the lev-els of T in control group (P >0.05).LH had decreased significantly after treatment in both two groups (P <0.01), FSH had not significant differences between pre and after treatment in two groups(P >0.05).The growthrate of follicle of two groups had elevated after treatment (P < 0.01).And the ovulation rate in dexamethasone treating group was higher than that in control group(P < 0.05), but there were not significant differences between the two groups in the clinical pregnancy rates(P >0.05).There were not significant differences between pre and after treatment in the levels of BMI in both two groups (P > 0.05).Conclusions Dexamethasone can decrease the T in plasm levels.It is good for ovulation induction in PCOS.

One case study of the development of ICF Core-sets had been discussed.ConclusionThe approach and procedures had been proposed for the ICF-based standardized measurement in rehabilitation medicine.

[Objective]To sum up LIN Qinfu(the fifth generation heritage of Quzhou LEI's medical )'s academic thoughts on clinical diagnosis and treatment of pediatric diseases. [Method]To study and research LIN Qinfu′s papers and books, to collect and arrange typical cases record, and his method of TCM differentiation of symptoms and signs, by these methods to summarize LIN Qinfu′s clinical experience in the treatment of pediatric diseases. [Result] LIN Qinfu pays attention to learn traceability, inherits two famous schools of medical of Xin'an WANG 's medical and Quzhou LEI's medical;Emphasize the comprehensive use of four diagnostic methods, observation is the most important in the diagnosis of pediatric. Advocate that children's physique is tender Yin-Yang,treatment for children should calm the mind, balance Yin-Yang,therapy and medication should be gentle and take account in the spleen and stomach. [Conclusion]LIN Qinfu has profound knowledge and rich experience of the treatment of pediatric diseases. and his clinical experience academic is medication unique, which is worthy of inheritance and promotion.

The (GCT)o polymorphism of the MICA gene was investigated in 100 patients with latent autoimmune diabetes in adult (LADA) and 145 healthy controls by PCR and denaturing polyacrylamide gel electrophoresis.The A5.1 allele was present at a significantly higher frequency in LADA group (0.340) than that in control group (0.183) (P

Objective To investigate the value of C- reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-?) in early diagnosis of neonatal sepsis. Methods Sixty- five newborns were divided into experiment group and control group, experiment group was also divided into sure group and doubtful group by blood culture We assessed the level of serum CRP, IL-6 and TNF-? in 24 hours and after 24 hours of clinical diagnosis of sepsis in experiment group, and examined the blood culture before antibiotic treatment Serum CRP, IL-6 and TNF-? were also examined in 3 to 6 days old. Results 1 The levels of serum CRP, IL-6 and TNF-? in experiment group were significantly higher than that in control group 2. The sensitivity of IL-6 and TNF-? were higher than CRP in 24 hours in experiment group. 3. After 24 hours, the sensitivity of CRP was elevated,and there was no statistical difference compared with the IL-6. Conclusion IL-6 and TNF-? are the credible marker in the early diagnosis of neonatal sepsis, and are more sensitive than the CRP, the IL-6 is the first sensitive marker.

In order to analyze the correlation between critical residues in the catalytic centre of BSH and the enzyme substrate specificity, seven mutants of Lactobacillus salivarius bile salt hydrolase (BSH1) were constructed by using the Escherichia coli pET-20b(+) gene expression system, rational design and site-directed mutagenesis. These BSH1 mutants exhibited different hydrolytic activities against various conjugated bile salts through substrate specificities comparison. Among the residues being tested, Cys2 and Thr264 were deduced as key sites for BSH1 to catalyze taurocholic acid and glycocholic acid, respectively. Moreover, Cys2 and Thr264 were important for keeping the catalytic activity of BSH1. The high conservative Cys2 was not the only active site, other mutant amino acid sites were possibly involved in substrate binding. These mutant residues might influence the space and shape of the substrate-binding pockets or the channel size for substrate passing through and entering active site of BSH1, thus, the hydrolytic activity of BSH1 was changed to different conjugated bile salt.

Glucaric acid (GA) is derived from glucose and commonly used in chemical industry. It is also considered as one of the "Top value-added chemicals from biomass" as carbohydrate monomers to produce various synthetic polymers and bioenergy. The demand for GA in food manufacture is increasing. GA has also attracted public attentions due to its therapeutic uses such as regulating hormones, increasing the immune function and reducing the risks of cancers. Currently GA is produced by chemical oxidation. Research on production of GA via microbial synthesis is still at preliminary stage. We reviewed the advances of glucaric acid applications, preparation and quantification methods. The prospects on production of GA by microbial fermentation were also discussed.

Objective To confirm the deviation between the present charge and real cost of nursing by comparing them between PICC and jugular veins catheter,and the advantages and disadvantages were weighed between them in tumor patients undergoing chemotherapy.Methods The cost of manpower,financial resources or materials for 106 patients with PICC,68 patients with jugular veins catheter were measured,accounted and statistically analyzed with the ladder sharing method for project cost.Comparing the cost between calculation cost and current charging standard,and the cost and clinical application was studied.Results The real cost of PICC was (2259.99±30.99)Yuan and current charging standard was 1532.79 Yuan,the deviation was -727.20 Yuan,and the real cost of jugular veins catheter was (393.86±33.93) Yuan,and current charging standard was 292.13 Yuan,the deviation was -101.73 Yuan.The complication rate was 12％ in PICC,17％ in jugular veins catheter.The real cost of nursing on PICC and jugular veins catheter was higher than current charging standard,and the real cost of single nursing on PICC was 5.74 times higher than jugular veins catheter.The cost remains unchanged with 4～6 course of chemotherapy treatments in a year.Conclusions The advantages of PICC are more than jugular veins catheter,so the preferred choice is PICC,and jugular veins catheter comes secondary.
