In this study Na2HPO4-Ca(NO3)2 system was used to synthesize hydroxyapatite (HA). Its synthetical method was simple and low in cost. With the physical-chemical characteristic observation and the animal experimentit was proved that HA was pure, with pores ranging from 20 to 200 ?m in diameter.The chemical structure of HA was similar to that of inorganic part of bones.An investigation of the histological changes and osteogenetic effectiveness of HA implanted was conducted and the mechanism of HA osteogenetic effectiveness is discussed. The study will provide scientific basis for the clinical use of HA as bone graft substitute.

AIM:To demonstrate the inhibitoary effects of Longkai Granules(LKG) against experimental prostatic hyperplasia and evaluate its toxicity on animals taking the granules orally. METHODS: The prostate exponent,DNA content in prostate tissue、the activity of acid phosphatase in serum or the wet weight of spermatophores and testicles in normal immature mice and in the hyperplasia model mice induced by subcutaneous injecting testooslerone spropionate or by implanting of the urogenital sinus were determined after administrating of LKG intragastrically to the mice.The single maximum dosage of LKG in mice and its long-term(13 weeks) toxicity in Wistar rats and Beagle dogs in orally was evaluated. RESULTS: LKG could decrease the weights of prostates and DNA content in the tissue in the normal immature mice in the amount of 20 and 40 g/kg once a day.LKG,in the amount of both 10,20 and 40 g/kg for 10 days and 20 and 40 g/kg for 30 days,could inhibit the hyperplasia of ventral prostates in the model mice induced respectively by the injection of testooslerone spropionate and by implanting urogenital sinus.LKG,in the(amount) of 100 g/kg for 13 weeks to Wistar rats,would lead to prostatic atraphy in alight degree,and its epithelial cells change in shape from column to flat and prostatic cavity being small,which did not recover in 4 weeks after stopping administration of tested drug to the animals.The single maximum dosage by ig in mice was 200 g/kg.There was no significant toxicity reaction in rats in the amount of 10,40 and 100 g/kg for 13 weeks or in Beagle dogs in the amount of 12 and 60 g/kg for 13 weeks. CONCLUSION: LKG can inhibit the prostatic hyperplasia and shows no visible toxic reaction in animals orally.

Objective To explore the association between ACTN3 gene R577X polymorphism and serum lipid levels in an elderly Chinese Han population.Methods This study was based on the ageing arm of The Rugao Longevity and Ageing Study (RtLAS).Genotyping was performed by Taqman MGB method.Lipids includedtotal cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C).Cut points of dyslipidemia were based on that reported in the NCEP ATPIII.We explored the associations between R577X polymorphism loci and dyslipidemia by using analysis of covariance and logistic regression analysis.Results Overall 1 618 samples was included (741 males and 877 females) in this study.Covariance analysis found that TC level of RR,XX and RX genotype in the general population were 1.34,1.37,1.43 mmol/L with an increasing trend (P =0.024);TC and LDL-C levels of RR,XX and RX genotype (TC:5.13,5.29,5.43 mmol/L,P =0.004;LDL-C:2.76,2.88,3.00 mmol/L,P =0.004) were significantly different in females.Logistic regression analysis showed that the increased copies of X allele were significantly associated with increased TC and LDL-C levels in the general population and females.For the general population,TC:OR=1.184,95%CI:1.030-1.361,P =0.018;LDL-C:OR =1.334,95%CI:1.101-1.588,P=0.003;For females,TC:OR=1.332,95% CI:1.102-1.616,P =0.003;LDL-C:OR =1.549,95 %CI:1.208-1.986,P =0.001.After adjusting for other covariates,the above associations remained significant.Conclusions ACTN3 gcnc R577X polymorphism is associated with plasma TC and LDL-C levels in elderly woman of Han populations in Rugao,China.

Objective To compare the safety and effectiveness of drug-eluting balloon (DEB) with paclitaxel and drug eluting stent (DES) in treating in-stent restenosis (ISR).Methods The clinical data of a total of 76 patients with ISR,who were admitted to authors' hospital to receive stem implantation during the period from January 2012 to September 2014,were retrospectively analyzed.According to the therapeutic means,the patients were divided into paclitaxel DEB group (n=32) and paclitaxel DES group (n=44).The general clinical information and coronary artery angiography findings were collected.The patients were followed up for one year;the all-cause mortality,cardiac death,myocardial infarction,in-stent thrombosis,target lesion revascularization,target vessel revascularization,and major adverse cardiac events were documented.Results No obvious difference in the general data of patients existed between group DEB and group DES (P>0.05).The incidences of left anterior descending artery ISR in DEB group and in DES group were 43.75% and 47.73% respectively.The ISR target vessel types of the two groups were quite similar (P>0.05).No statistically significant differences in ISR type,ISR lesion type and characteristics of in-stent restenosis existed between the two groups (P>0.05).One-year following-up examinations indicated that no statistically significant differences in all-cause mortality,cardiac death,myocardial infarction,in-stent thrombosis,target lesion revascularization,target vessel revascularization,and major adverse cardiac events existed between the two groups (P>0.05).Further analysis revealed that no significant difference in event-free survival existed between the two groups (P>0.05).Conclusion For the treatment of ISR,the use of paclitaxel DEB is safe and feasible,its curative effect is not less than DES.

Objective To explore the clinical pharmacist’s role in drug therapy and monitoring for the patient with postoperative MRSA infection. Methods Clinical pharmacists participated in planning anti-infective treatment, antimicrobial medication selection, identification of high-risk factors for MRSA infection, evaluation of vancomycin efficacy, dosage adjustment using TDM technology, monitoring and management of vancomycin adverse reactions. Results With the pharmaceutical care provided by clinical pharmacists, the patient received effective treatment with minimal vancomycin-related adverse reactions. Conclusion Clinical pharmacists played an important role in accelerating patient recovery by rational and safe medication use.
