Objective To study the efficacy of alendronate in treatment of postoperative residual pain with osteoporotic vertebral compression fractures(OVCF) of vertebroplasty.Methods 62 patients with OVCF from September 2013 to October 2014 were divided into observation group and control group, each had 31 cases.All patients were given calcium carbonate D3 tablets 1 day after surgery, observation group were given alendronate on this basis.The degree of pain score between two groups pre-and post-treatment two weeks, one month, two months were observed and compared.Pain improvement in two groups were observed, and activity ability score, painkiller use and bone mineral density between two groups pre-and post-treatment were compared.Results The pain scores in observation group a month postoperative was (0.8 ±0.4) points and (0.4 ±0.2) points after two months, were significantly lower than those in control group[(1.6 ±0.7) points, (1.1 ±0.8) points, P<0.05].The excellent rate of pain improvement in observation group(83.87%) was significantly higher than that in control group (58.06%, P <0.05) .After treatment, activity ability score in observation group was (1.13 ±0.53) points and painkiller usage was (0.44 ±0.07) times per day, all significantly lower than those in control group [(1.79 ±0.89) points, (0.89 ±0.12) times per day, P<0.05].BMD level in observation group was (5.78 ±1.02)%, higher than that in control group[(3.21 ±0.79)%, P<0.05].Conclusion Alendronate in treatment of osteoporotic vertebral compression fractures vertebroplasty postoperative residual pain has good early outcome and low adverse reactions, and security is relatively high.

Objective To understand the effects of 17?-estradiol on MCF-7 cell proliferation and the regulation of estrogen receptor-related recepto(rERR?).Methods MCF-7 cells were treated with 17?-E2 at the doses of 10-12,10-11,10-10,10-9,10-8,10-7 and 10-6 mol/L for 24 h.Dimethyl sulfoxide were used as the solvent control.MTT method was used to determine inhibitory rate of MCF-7 proliferation,and the cells were treated with 17?-E2 at the doses of 10-10,10-9,10-8 and 10-7 mol/L for 24 h.RT-PCR method was used to detect the expression level of ERR?.Results Cell proliferation were promoted by exposure to 17?-E2 at the doses of 10-12,10-11,10-10,10-9,10-8,10-7 and 10-6 mol/L,the proliferation rate were 112.09%,122.09%,123.42%,120.46%,124.60% and 109.23% respectively,however,cell growth was inhibited at 10-6 mol/L of 17?-E2.The expression of ERR? in MCF-7 cells was upregulated at the doses of 10-10,10-9,10-8 and 10-7 mol/L when cells were treated with 17?-E2 for 24 h.Conclusion In certain dosage range,cell proliferation and expression of ERR? can be promoted by 17?-E2,which suggests that ERR? should play an important role in the process of MCF-7 cells growth.

Objective To study the effects of prenatal exposure to low level lead on the physical and neuro-behavioral development of mice and the interaction between lead and zinc. Methods Kunming pregnant mice were provided with drinking water containing lead, zinc and lead-zinc jointly and respectively. The body weight of maternal mice, offspring's survival rate and body weight were observed. Neuro-behavioral development of offspring was assessed by observation of offspring's behavior performance. The levels of dopamine (DA), 5-hydroxytryptamine (5-HT) and malonaldehyde (MDA) in offspring's brains were measured. Results At the doses of lead and zinc which did not effect the increase of maternal body weight during pregnancy, the lead exposure group showed low survival rate, growth retardation and delay of physiological development and neonatal reflexes in the offspring, the levels of DA and MDA in offspring's brains increased compared with the control group. Offspring's low survival rate and growth retardation couldn't be antagonized by zinc, but equal mole as lead of zinc could inhibit the harmful effects on neuro-reflex development. Zinc could also inhibit the increase of DA and MDA levels in offspring's brains induced by lead . However joint exposure to lead and half dosage as much as lead of zinc could deteriorate the effects on delay of physical, neuro-behavioral development and accelerate the DA and 5-HT decompose compared with that in the lead exposure group. Conclusion The harmful effects on offspring's growth and neuro-behavioral development could be induced by prenatal exposure to low level of lead. The types of joint-effect of lead and zinc were different according to the concentration of zinc, which indicated that the zinc-lead interaction was very complicated and it should be very prudent to antagonize lead toxicity using zinc.

Objective To investigate the mechanism of Shengji-hongfen Cream(SJHFC)affecting basic fibroblast growth factor(bFGF)in wound and hastening wound healing.Methods Rabbit models of cutaneous deficiency and infection were setup.Self-contrast observation was used for comparing the two wound sides of model rabbit,which were administrated with SJHFC(treatment group)and vaseline(control group)respectively.Microstructure of wound surface and changes of bFGF weTe observed and measured.Results The content of fibroblasts,phlogocyte,collagen and blood vessel in the SJHFC group increased markedly,compared with the control group after one week.The content of bFGF was significantly changed than the control group at the 3rd and 7th day(P<0.05).Conclusion SJHFC Can promote bFGF content of the wound,that maybe the mechanism of its hastening wound healing.

Objective To study bacterial conditions in amniotic cavity of the third trimester and the delivery. Methods Patients underwent cesarean section due to various reasons were randomly enrolled in the study. Ten ml aqua amnii taken from using aspesis were cultured and the bacteria were identified and tested for drug sensitivity. All patients were not treated with antibiotics before and during operation,conventional antibiotics treatnent was used after operation. The patients were divided into 3 groups based on their status: 34 cases of premature rupture of membrane ( PROM ), thirty-four cases of labor without PROM, and 27 cases of pregnancy without PROM. The positive rate, species , distribution and drug sensitivity of bacteria in the 3 groups were analyzed. Results The positive rate was 61.8% (21/34) in PROM ,52. 9% ( 18/34 ) in labor without PROM,11.1% (3/27)in pregnancy without PROM. The positive rates were significantly different among the 3 groups (x2 = 17.29 ,P =0.000). However, there was no significant difference between the labor without PROM group and the pregnancy without PROM group ( x2 = 0.541 , P = 0.462 ). Staphylococcus epidermidis was the most common isolated bacteria, following by staphylococcus aureas, streptococcus, colon bacillus, and pseudomonas. There were no significant differences of bacterial species between labor without PROM and pregnancy without PROM( x2 = 11.9,P =0.535 ). The relative higher positive rate in the labor without PROM and PROM indicated that they were important inducement of bacteria infection. There were no significant difference on positive rate and bacteria species distribution between the PROM and labor without PROM group,which suggested that up-bound along vagina to amniotic cavity was the most common route of infection. Sensitive antibiotics should be given to the patients of PROM and labor without PROM targeted at staphylococcus,streptococcus, colon bacillus and monad. Antibiotics such as Cephems, Penicillins and Clindamycin were sensitive to various bacteria and safe to both mother and baby, thus were recommended. Quinupristin, Vancomycin,Furantoin, Fusidic ,Teicoplanin, Amikacin and Meropenem were also sensitive to various bacteria, but due to their side effects and the principle of ladder antibiotics using, they were recommended as second line antibiotics. Conclutions Up-bound along vagina to amniotic cavity is the most common route of infection. For rupture of membrane and labor without PROM patients, antibiotics should be given, and strict aseptic technique,washing cavity and incision, using antibiotics after operation are necessary to prevent infection.

Objective To investigate the effects of human S100A6 on ?-catenin in human osteosarcoma cell lines MG63 and U2OS.Methods Cell lines MG63 and U2OS were infected by recombinant adenoviruses carrying human S100A6 and its siRNA gene,AdS100A6 and AdSiS100A6 respectively,to up-regulate and down-regulate the expression of S100A6. Then RT-PCR,Western blot and immunocytochemistry were used to detect mRNA and protein (level and/or distribution) of ?-catenin.Results In both cell lines,with up-regulated S100A6,expression of ?-catenin mRNA and protein increased(P
