Objective:To evaluate the efficacy and safety of tirofiban,a platelet glycoproteinⅡb/Ⅲa Inhibitor,in percutaneous coronary intervention(PCI)of patients with acute non-ST segment elevation myocardial infarct(NSTEMI).Methods:A total of 114 patients with acute NSTEMI were enrolled in the trial from Sep.2005 to Jan.2007;they were randomly divided into 2 groups:tirofiban group(n=57)and placebo group(n=57).Patients in tirofiban group were given tirofiban for 24 h after PCI.All patients were routinely given heparin,aspirin and clopidogrel before CPI.The composite occurrence of death,myocardial infarction(MI),need for target vessel revascularization(TVR)after PCI,and the adverse effects(hemorrhage and thrombocypenia)were compared between the 2 groups.Results:One(1.8%)patient had angina pectoris and the other(1.8%)developed subacute thrombus in control group within 24 h after PCl;there was no such event in the tirofiban group.Two(3.6%)patients developed angina pectoris and 2(3.6%) developed subacute thrombus within 30 days after PCI in control group;one patient(1.8%)in birofiban group developed angina pectoris and one patient in birofiban group developed subacute thrombus.Each group had one case(1.8%)of upper digestive tract bleeding during hospitalization.No intracranial hemorrhage,skin/ mucosa hemorrhage,thrombocytopenia,or-death occurred in the 2 groups.Intravenous tirofiban treatment reduced the composite occurrence of death of NSTEMI patients after PCI(P

Objective To study the killing effect of focused ultrasound activated-hematoporphyrin on H-22 and its optimum exposure time.Methods The distribution of hematoporphyrin in H-22 cells was measured by a fluorescence photometer,the uhrastructure changes were evaluated at different time with a scanning electron micro- scope after treatment with focused ultrasound at the frequency of 1.43 MHz and intensity of 1.0 W/cm~2, 2.0 W/cm~2,3.0 W/cm~2,respectively,in combination with HpD.Results The concentration of HpD in the H-22 cells reached its peak after being added to H-22 tumor cells for 45 minutes,which will produce the hest anti-tumor effect when activated by ultrasound.Morphological observation showed that HpD alone had a slight influence on H-22 cells;ULtrasound alone showed an anti-tumor effect on tumor cells,which was dosage-dependent.Ultrasound dia- thermy in combination with HpD has more effective in terms of its antitumor effect when compared with uhrasound dia- thermy alone.Conclusion The killing effect on H-22 tumor cells of sonodynamic treatment was dependent on the intensity of uhrasound and the content of HpD in the cells,as well as on the time of action of both uhrasound and HpD.

A PCR method was used to amplify the sequence encoding the mature peptide of?-mannanase of Bacillus subtilis. The gene was inserted into the Pichia pastoris vector pPIC9K, downstream of?-factor signal peptide sequence. The resultant recombinant plasmid pPIC9K-MAN was lineared by BglII digestion and introduced into the host Pichia pastoris GS115 by PEG method. After screen, the recombinant P. pastoris strain MAN22 was obtained and fermented in large scale 5L fermenter. The recombinant mannanase activity could reach to 1102IU/ml. The properties of the recombinant mannanase were characterized.

Objective To analyse the effects of serum estradiol levels during controlled ovarian hyperstimulation (COH) on the outcomes of in vitro fertilization and embryo transfer (IVF-ET). Methods The clinical data of 472 patients undergoing IVF-ET with GnRH analogues recombinant FSH long protocol were retrospectively analysed. The area under the curve (AUC) of estradiol (E2) level was calculated during COH, and patients were categorized into groups according to the percentile of AUC of E2(AUCE2) during COH. The general characteristics and parameters related to the outcomes of IVF-ET were compared among groups. Results The 10th percentile and 90th percentile of AUCE2 were 3 347.0 pmoL/L and 14 414.3 pmol/L, respectively. Four hundred and seventy-two patients were divided into lower reaction group (AUCE2 3 347.0 pmol/L, n=48), normal reaction group (14 414.3 pmol/L>AUCE2 > 3 347.0 pmol/L, n=376) and higher reaction group (AUCE2≥14 413.3 pmol/L, n=48). There was no significant difference in age, body mass index, baseline follicle stimulating hormone level, time of treatment with gonadotropin, endometrium thickness on day of transfer and embryos transferred(P>0.05). Compared with lower reaction group and normal reaction group, the number of oocytes per retrieval and number of embryos frozen were significantly larger(P<0.01) and the mild/severe ovarian hyperstimulation syndrome rate was significantly higher in higher reaction group(P<0.05). There was no significant difference in fertilization rate, cumulative embryo score, high-grade embryo rate, clinical pregnancy rate and implantation rate among groups (P> 0.05). Conclusion Sustained snpraphysiological serum E2 levels during the COH process do not adversely affect the quality of oocytes and embryos, clinical pregnancy rate and implantation rate to some extent in IVF-ET.

OBJECTIVETo observe effects of serum Bushen Huoxue prescription(Chinese characters) on classic Wnt/β-catenin signaling pathways of osteoblasts, and explore mechanism of Bushen Huoxue prescription (Chinese characters) for preventing osteoporosis.
METHODSTwenty health female rats were randomly divided into two groups, including Bushen Huoxue (Chinese characters) group and saline group,10 in each group. Bushen Huoxue (Chinese characters) group and Saline group were gavaged Bushen Huoxue and saline every day for 1 week. Bushenhuoxue containing serum and saline containing serum were got according to methods of serum preparation of drug-containing. The osteoblasts was cultured with neonatal rat skull according to Enzyme Consumer Law, and was identified by Wright-Giemsa staining (R-J) and alkaline phosphatase staining (ALP). The third generation of osteoblasts was divided into three groups, including saline group, normal group,Bushen Huoxue (Chinese characters) group. Each group were added to 15% appropriate medium. ALP activity of osteoblasts and osteoblasts proliferation rate were tested, mineralized nodules were observed, the expression of β-catenin, Runx2, Osx mRNA of osteoblasts were tested by RT-PCR.
RESULTSThere was blue granules in cytoplasm, cell nucleus was flint with 1 to 3 nucleoli showed by R-J staining, morphology of osteoblasts were cultured. ALP staining showed cytoplasm with purple granules, the results showed that the cultured cell was osteoblasts. The content of ALP in Bushen Huoxue (Chinese characters)group was (6.272±0.131) ,appreciation rate was (0.81? 0.172), and could significantly improve differentiation and proliferation activity of osteoblasts compared with Saline group (P< 0.01). There were four different size orange nodules, the Maximun nodule was 1.0 x 1.0 cm in Bushen Huoxue (Chinese characters) group after Alizarin red staining, the results showed Bushen Huoxue (Chinese characters)group could obviously improve mineralization of osteoblasts. The expression of mRNA of β-catenin, Runx2 and Osx in Bushen Huoxue (Chinese characters)group were (1.782±0.944), (1.935±0.994) and (1.610±0.811) by RT-PCR,it was significantly increased compared with saline group (P<0.01), but there was no difference between Bushen Huoxue (Chinese characters)group and normal group (P>0.05).
CONCLUSIONBushen Huoxue (Chinese characters)group could obviously promote differentiation, proliferation and mineralization of osteoblasts through activation of Wnt, β-catenin signaling pathway. It suggested that the mechanism of action of Bushen Huoxue (O'f f Il.t)particle clould prevent osteoporosis through the activation of Wnt, β-catenin signaling pathway.

Chronic osteomyelitis is one of the most common disorder in clinic. In recent years due to diabetes, peripheral vascular disease and trauma induced disease increased, the prevalence rate increased. With the development of magnetic resonance imaging and CT imaging technology, it greatly improved the accuracy of clinical diagnosis of chronic osteomyclitis and ability to describe the infection characteristics, and provide a reliable basis for clinical treatment. The current research on chronic osteomyelitis mainly concentrated on the aspects of imaging applications and ways of using antibiotic optimization control inflammation, defect restoration and reconstruction of blood supply and treatment. But the best time to the antibiotic therapy and the use of program is still uncertain, for after debridement, bone grafting time and defect repair function of fast recovery still need further research.
