Objective To explore the efficacy and safety of hormone replacement therapy with combination of Fosamax and simple use of Fosamax in osteoporosis and steopenia of perimenopausal women.Methods One hundred and thirteen perimenopausal women with osteoporosis accepted treatment in Outpatient Clinic of Panyu Convalescent Hospital of Guangzhou from December 2010 to June 2014 were chosen and divided into the control group (n=55) and the observation group (n=58) according to therapeutic method.The control group was treated with Fosamax alone while the observation group was treated with HRT basing on the simple use of Fosamax.The therapeutic effect,lumbar and hip bone mineral density(BMD) level,tibial ultrasound velocity (SOS) and T values of tibia,gonadal hormone concentrations,endometrial thickness and adverse reaction of the two groups before and after the therapy were compared.Results (1) The total effective rate of the observation group after the treatment was 93.10％,significantly higher than tbat of the control group (78.18％,x2=3.829,P=0.034).(2) Before and after treatment in two groups,there were statistically significant differences in terms of lumbar spine BMD,hip BMD,SOS of tibia,blood follicle stimulating prime (FSH) and estradiol(E2) (P＜0.05),and there were statistically significant differences between the two groups after the treatment in terms of lumbar spine BMD,hip B MD,SOS of tibia,FSH and E2 (t =3.389,5.012,3.997,5.829,3.902;P=0.035,0.028,0.033,0.024,0.038).(3) There was statistically significant differences in term of the incidence of adverse reactions between the observation group and the control group (6.90％ vs.16.36％;x2=8.273,P=0.012).Conclusion Compared with alone use of Fosamax,the therapeutic effect of hormone replacement therapy with combination of Fosamax and in osteoporosis and steopenia of perimenopausal women is more significant with low occurrence rate of adverse reaction.It is worth popularization.

OBJECTIVE:To study the effect of Zhenqi fuzheng capsules(ZQFZ)on the immune function of hypoimmune mice.METHODS: The hypoimmune mice model was established using cyclophosphamid;the effects of ZQFZ on the nonspecific immunity,cell immunity and humoral immune function of mice were observed by determining the function of peritoneal macrophage,the delayed hypersensitivity and serum antibody of hemolysin etc.RESULTS:ZQFZ significantly promoted the function of peritoneal macrophages,improved the phagocytic rate and phagocytic index,markedly enhanced the dinitro-chlorobenzene-induced delayed hypersensitivity,and up-regulated the serum antibody level of hemolysin.CONCLUSION:ZQFZ have remarkable action in promoting the immune function of hypoimmune mice.

Based on the data of the ISI "Journal Citation Report" in 2006 edition,a statistics for the 88 mi-crobiology science journals has been made. The results showed that these 88 learned journals were published in 16 countries with 3 languages,especially English. And the main countries were United States,England,Netherlands and Japan. The average data of articles and total cites of the 88 journals were 165 and 5226.64,respectively. Moreover,the average data of impact factor and immediacy factor were 3.154,0.45 and 5.84,respectively. Finally,fifty-five learned journals with impact factor over 2.0 were introduced from these jour-nals to be referenced.

Objective:To study the role of APACHEⅡscore pre-operation to infusion of blood preparation during the periods of hepatectomy.Methods:The correlation between APACHEⅡscore pre-operation and infusion of erythrocyte suspension and plasma were analyzed retrospectively in 104 cases who suffered from hepatectomy.Results:Those whose APACHEⅡscore were less than 5 had significantly lower volume of bleeding and lower infusion of erythrocyte suspension and plasma during the operation than those whose APACHEⅡscore were not less than 5(P

0.05),the clinical control rate were 67.65% and 52.94% (P

Objective:To investigate genetic polymorphism of four X chromosome short tandem repeats(X-STR)loci(DXS7132、 DXS6789,HPRTB,DXS8378)in Chongqing Han population.Methods:EDTA-blood samples were collected from the unrelated individuals in Chongqing.After being extracted with Chelex-100 method,the DNA samples were amplified by PCR technique.The PCR products were analyzed by PAGE,genotyped with silver stain method.Hardy-Weinberg equilibrium was tested,and then used direct counting method to calculate allele and genotype frequency of these four loci.Results:The polymorphisms of all four STR loci were obtained from 120 unrelated females and 91 unrelated males from Chinese Han group.?2 tests on the genotype frequencies in female reveal that genotype frequencies in females did not depart from Hardy—Weinberg equilibrium.Conclusion:It was suggested that DXS7132,DXS6789,HPRTB,DXS8378 locus are suitable for individual identification and paternity testing,and we provide new selectable STR markers for chromosome X haplotype in forensic application.

Objective:To investigate the effect of brain tissue extract of hypoxia-preconditioned mice (BHP) on tolerance of NGF-induced differentiated PC12 cells to hypoxia and the optimal concentration for protective effect.Methods:The mice model of acute repetitive hypoxia was reproduced and BHP was prepared.BHP was added into the cultures of 4～5 day differentiated PC12 cells and the final protein concentrations of BHP were 1.0、10.0、100.0?g/ml(BHP groups) respectively.Brain tissue ex- tract of normal mice(BN) at the same three protein concentrations were used as controls(BN groups) and PBS solvent control groups were also prepared in which only PBS was added(PBS groups).Then differentiated PC12 cells were cultured in hypoxia (2%O_2).After 24,48,72 hours'hypoxia,colorimetric method(OD_(570nm)) of tetrazolium salt MTT staining was adopted to determine cell viability and lactate dehydrogenase(LDH) leakage assays were also conducted at the same time.Besides,apoptotic per- centages at late stage(72 hours' hypoxia) were detected.Results:After 24 hours' hypoxia,OD_(570nm) values of BHP groups with protein concentrations being 10.0、100.0?g/ml were significantly higher,but their LDH leakage percentages were significantly lower than those of BN groups with the same protein concentrations and of hypoxic PBS group.With hypoxia prolonging,BHP gradually lost the protective effect.At the time point of 72 hours' hypoxia,OD_(570nm) values of only BHP group at 100.0?g/ml protein concentration was significantly higher than that of the corresponding BN groups,its LDH leakage percentage and apop- totic percentage was significantly lower than those of the hypoxic PBS group.Conclusion:The effects of BHP on tolerance of differentiated PC12 cells to hypoxia depend on its concentrations and on its treating time.Besides,BHP at final concentration of 100.01?g/ml protein showed steady,prolonged protective effect.

Objective:Through research of corneal transparency and related influential factors,the authors try to look for some clinical variety regulations after penetrating keratoplasty(PKP) in order to enhance the rate of surgery success.Methods:104 blind patients due to corneal disease (107 eyes) undergone PKP were followed up on months 1,3,6,12,18,24 and 36.Clarity of cornea,corneal endothelial cells and all kinds of complications were recorded besides regular examinations.Results:Grafts were transparent in 82 of 107 eyes on month 1(76.6%),in 69 of 90 eyes on months 6 (76.7%),in 51 of 81 eyes on months 12(63%),in 26 of 40 eyes on months 12 (65%) after PKP.Corrected vision were improved especially in patients of grafts transparency.Vision of patients with transparent grafts were more than 0.1 in 67 of 82 patients(82%) on month 1,in 59 of 63 patients(94%) on months 3,in 66 of 69 patients(96%) on months 6.Conclusion:PKP is an important method to corneal disease blind patients.Rejection was the major cause affecting graft transparency.

Objective:To research eyes refraction varieties and related influence factors undergone PKP.Methods:Sixty-two corneal diseases with PKP were followed up by ophthalmologist concentrating on corneal diseases on month 1,3,6,12,24,36.They had engaged in optometry and tried lens on patients besides regular examination,and had done statistical analysis of refraction change.Results:Eye refraction varieties were remarkable in 12 months especially in 1 to 6 months but stable after 12 months after PKP.Most of them had different degrees and kinds of astigmatism.Conclusion:Eyes refraction varieties were remarkable in 12 months after PKP and astigmatism occurred easily.There were some main factors:conditions before operation,design and manipulation during operation,and complications after surgery.
