Exogenous gonadotropins are widely used in controlled ovarian stimulation (COH) for patients undergoing in-vitro fertilization (IVF),because of the effect of follicle maturation and ovulation.Except for environmental factors such as age and ovarian reserve,genetic variability seems also to be a key factor in determining the ovarian response to the exogenous gonadotropins.In this review, the reason for the interindividual difference in ovarian resoponse as well as the influence of the genetic polymorphisms of FSHR and ESR on COH and IVF outcome has been summarized.

Objective:To apply positive composite training on gynecologic tumor patients for psychological intervention,comparing with the general intervention,and to provide a new way to alleviate physical and psychological symptoms of patients and improve their quality of life.Methods:In Beijing Cancer Hospital,80 surgery and chemotherapy patients with gynecologic tumor were chosen and divided into control group (40 cases,to receive health education and supportive treatment) and intervention group (40 cases,to receive comprehensive training),whose condition and basic situation were matching.After intervention,the scores of Symptom Checklist 90 (SCL-90) and Quality of Life Questionnaire- Core 30 (QLQ-C30) were compared between the two groups.Results:After intervention,the SCL-90 scores in intervention group (outside terrorist and interpersonal sensitivity factor) were lower than that in control group[such as total score,(1.43±0.34) vs.(1.87±0.43),P<0.001].The scores of physical function,role function,emotional function,cognitive function,and general health in the QLQ-C30 about patients with chemotherapy in intervention group were higher than those in controls[such as general health,(62.50±10.29) vs.(52.50±15.78),P=0.024].And the scores of fatigue,nausea and vomiting,pain,insomnia,appetite loss,constipation,and diarrhea factors were lower than those in control group[such as fatigue,(52.77±16.07) vs.(65.55±20.36),P=0.034].Conclusion:The positive composite training is able to alleviate the physical and mental symptoms and improve their quality of life in gynecologic tumor patients.

pPIC9 was used as a template and ?-factor gene of Saccharomyces cerevisiae was amplified by PCR.The gene was cloned in the intracellular expression vector pYES2/CT for Saccharomyces cerevisiae and the secreting expression vector named pYES2/CT/?-factor(pYC?)was constructed.The gene of mannase(man)from recombinant vector of pKLAC1-man(pKLman) was cut by restriction enzymes and linked with pYC?.This recombinant vector pYC?-man was used to determine the secretory ability and stability of pYC?.The excellent secretory ability of pYC? was proved by two experiments.One showed that INVSc1/pYC?-man clones formed the clear rings around the clones on the medium contained trypan blue,while INVSc1/pYC? clones had no rings.Further analysis of mannase activity of extracellular supernatant and intracellular extracts showed that both extracellular and intracellular mannase activities of INVSc1/pYC? were not detected,while INVSc1/pYC?-man had evident extracellular mannase activities and no intracellular mannase activities.The stability of pYC? was also very good proved by continuous cultivation for about 150h.

Objective To explore the effect of the application of Rivaroxaban in the treatment of the patients with total hip replacement.Methods 114 patients with total knee arthroplasty were randomly divided into control group and observation group,57 cases in each group.All patients were operated by the standard operation in the department of orthopedics.The control group was given low molecular weight heparin before operation.The patients in the observation group were treated with 8h after the operation,and the color Doppler ultrasound was performed on the patients with double lower limbs and lungs after 2 courses of treatment.Observation of drainage,two groups of patients after total blood transfusion,blood index,adverse reactions and deep vein thrombosis cases.Results In the observation group,the deep vein embolism rate (1.75%)was significantly lower than that in the control group of 12.28% (χ2 =4.25,P <0.05 );The postoperative drainage volume,blood transfusion and blood index of the two groups had no significant differences (t =0.57,0.82,1.03,all P >0.05).During the treatment,the patients in the two groups were adverse reactions.Conclusion The effect of oral administration of Rivaroxaban after hip replacement surgery is remarkable,which can effectively reduce the incidence of deep venous thrombosis,and it is safe,and it is worthy of clinical application.

Objective To study the role of NF-?B pathway in HGF (hepatocyte growth factor)-mediated proliferation of WB F-344 cell. Methods WB F-344 cells were treated with HGF in different concentrations i.e. 0, 20, 40, 80 and 100ng/ml. After incubation for 24 hours, proliferation effect was analyzed with [3H] Thymidine. WB F-344 cells transfected with I?B? plasmid mutants by liposome transfection were used to block NF-?B activity, and then they were treated with 40ng/ml HGF for 0, 15, 30, 60 and 120min, respectively. The nucleoprotein was extracted to determine the NF-?B DNA-binding activity by EMSA. WB F-344 cells were also transiently transfected with BD Great EscA PeTM SEAP vector with liposome and then stimulated with HGF in different concentrations (0, 10, 20, 40ng/ml) for 8 hours to detect the NF-?B transcription activity. WB F-344 cells were pre-treated with NF-?B inhibitor BAY-11-7082 or ASA, and then with 40 ng/ml HGF for 24 hours to analyze the proliferation effect by [3H] Thymidine. Results HGF promoted the proliferation of WB F-344 cells and exhibited positive dose-effect tendency. HGF could enhance the NF-?B DNA-binding activity. NF-?B complexes appeared 15min after addition of HGF. The complexes reached the peak value 30-60min after addition of HGF and then decreased gradually. HGF could also enhance the NF-?B transcription activity, exhibiting positive dose-effect tendency. HGF-mediated proliferation was remarkably inhibited when NF-?B activity was blocked by BAY-11-7082 or ASA. In WB F-344 cells transfected with p-CMV-I?B?, the proliferative response to HGF was completely interrupted. Conclusions HGF may promote the proliferation of WB F-344 cells in a positive dose-effect tendency. The activation of NF-?B is necessary for HGF-mediated proliferation of WB F-344 cells.

Center vein puncture is important to the clinical infusion technology, however, its correlation infection rates rising trend year by year, especially catheter-related bloodstream infections have become one of the main reasons for primary bacteremia, seriously affected the patients survival rate, and the processing method of catheter-related bloodstream infections are intricate. The treatment and nursing of adult bloodstream infections caused by short-term central venous catheter (including peripheral central venous catheter placement) according to the provisions of the Infectious Diseases Society of America to update the catheter related infections of diagnosis and treatment guidelines are reviewed in this paper, to provide reference for management of adult short-term central venous catheter.

Objective To assess the efficacy and safety of aspirin for type 2 diabetes mellitus(T2DM).(Methods)Electronic database searching was performed on Medline,Cochrane Library and CBM,and the data from the beginning of the database to October 2005 were included.Randomised and quasi-randomised trials concerning aspirin treatment for T2DM were selected and assessed for the methodological quality,and the extracted data were performed Meta-analysis by statistical software RevMan4.2.8. Results Fourteen randomised and quasi-randomised trials met the inclusion criteria,including 7 papers of aspirin treatment for T2DM,3 papers of aspirin treatment for cardiovascular complication of T2DM and 4 papers of aspirin treatment for type 2 diabetic retinopathy.Compared with placebo treatment,aspirin showed significant positive effects on lowering blood glucose(SMD,0.73;95%CI,(-1.11 ~-0.36;)P=0.0001).In diabetic patients,aspirin treatment was associated with a significant reduction in the total cardiovascular events(RR,0.78;95%CI,0.68 ~ 0.98;P=0.03).Aspirin treatment neither lowered(nor increased) the risk of the development of diabetic retinopathy(RR,1.02;95% CI,0.97 ~ 1.07;P=0.54).(Conclusion Aspirin treatment) can be a choice for T2DM,especially for the patients who have evidence of cardiovascular disease or have high risks for cardiovascular disease.
