Objective To determine the relative factors of the onset of repeated ectopic pregnancy. Methods The clinical data of the first time ectopic pregnancy of 28 cases with repeated ectopic pregnancy were analysed, and compared with those of 56 cases of non-repeated ectopic pregnancy onsetting at the same period. The factors measured included: age at onset of disease, age at first coitus, gravidity, parity, methods of contraception, duration of amenorrhea,duration of vaginal bleeding, serum ?-human chorionic gonadotropin level, volume of intraperitoneal bleeding, types of ectopic pregnancy, methods of therapy and inflammation evidence of fallopian tube. Logistic regression analysis was performed to determine the relative factors for onset of repeated pregnancy. Results The risk factors and its odds ratio (OR) from the multivariate analysis were as follow: anastomosis of the tube(62.74, P=0.043), positive evidence of inflammation of the tube (54.85, P=0.000), no contraception (11.29, P=0.002), contraception by condom occasionally (4.75, P=0.046); the protective factors and its OR were as follow: therapy being salpingectomy and sterilization of the opposite tube(0.06, P=0.049), oral contraception (0.10, P=0.050) and pharmacotherapy (0.33, P=0.002). Conclusions The risk factors of onset of repeated ectopic pregnancy include: anastomosis of the tube, positive evidence of inflammation of the tube, no contraception and contraception by condom occasionally; the protective factors include: therapy being salpingectomy and sterilization of the opposite tube, oral contraception and pharmacotherapy.

Objective The present study was undertaken to investigate the properties of nonlinear dynamics of EEG and the changes in depth of anesthesia with real-time approximate entropy (ApEn) and complexity (Cx) nonlinear indexes monitoring during anesthesia. Methods EEG was recorded in 65 in-patients. They were randomly divided into 4 groups: isoflurane, sevoflurane, desflurane (n=15, respectively), and propofol intravenous anesthesia (n=20) groups. The EEG derived parameters ApEn and Cx non-linear indexes were calculated simultaneously during the whole operation including rest state with eyes closed, anesthetic induction, intraoperation, recovery, post-operation awaking. Results ApEn and Cx nonlinear indexes remained the highest during rest state. Both of them kept decreasing during anesthetic induction. They dropped to a relative lower value and leveled off in the intra-operation period. Both of them rose gradually during recovery period and returned to a high level in the post-operation awaking period (correspondingly, ApEn: 0.87, 0.78, 0.55, 0.64 and 0.83. Cx: 0.58, 0.54, 0.38, 0.46 and 0.57). Conclusions With ApEn and Cx non-linear indexes, changes in depth of anesthesia from EEG signal could be real-timely monitored and precisely measured. Nonlinear dynamic analysis might provide us with more information about consciousness and cognition during general anesthesia.

Parkinson's disease(PD) is a common neurodegenerative disorder with no effective protective treatment,characterized by a massive degeneration of dopaminergic neurons in the substantia nigra(SNpc) and the subsequent loss of their projecting nerve fibers in the striatum.The major neurochemical manifestation of this disorder is the loss of the neurotransmitter dopamine(DA) in the striatum as a result of the progressive degeneration of the dopaminergic neurons in the substantia nigra.There have been significant progresses in recent years reporting on the use of mesenchymal stem cells(MSCs)in gene therapy,with specific application towards PD.MSCs,a kind of multipotent adult progenitor cells,are considered as a useful vehicle for cell and gene therapy because of their multiple differentiation potentiality and self-transplantation.The present study was focused on treating rat model of PD using human tyrosine hydroxylase gene(hTH),human aromatic L-amino acid decarboxylase gene(hAADC) and human GT Pcyclohydrolase I gene(hGCH-I) engineered MSCs,in order to provide a better understanding about the application of these cells in the therapeutic benifit of PD.The gene of hTH,hAADC and hGCH-I were introduced via recombinant adeno-associated virus(rAAV) infection into the MSCs in vitro.The genetically modified MSCs expressing hTH,hAADC and hGCH-I were transplanted into the striatum of PD rat models.The behavior,the nigra-striatal level of DA and its metabolite were detected.The results of present study were shown as follows:hTH,hAADC,hGCH-I and LacZ gene were transfected into MSCs with adeno-associated virus vectors.The HEK293 packaging cells(ATCC) were transfected with the plasmids of pAAV-hTH,pAAV-hAADC,pAAV-hGCH-I,pAAV-LacZ,pAAV-RC,pHelper by using calcium phosphate precipitation.Titer was detected using HT1080 cells.Viral particles were collected and used to infect MSCs.The purified modified MSCs expressing the three kinds of genes were selected separately and were grafted in the striatum of the PD model rats in the lesion side.The MSCs genetically modified suvived well 12 weeks after transplantation.The improvements of the behavior were observed every week after transplantation.Compared with the control group,the rounds of asymmetric rotation after apomorphine administration decreased in the groups double or triple genes engineered MSCs grafted(p

Objective To evaluate the value of tomographic ultrasound imaging(TUI)in the fetal heart screening.Methods One hundred and ten volume datasets acquired from normal fetal heart in the second trimester with spatio-temporal image correlation(STIC) were evaluated offline with TUI. The Bmode and CDFI static images as well as the dynamic loops of one cardiac eycle could be reviewed simultaneously. The visualizing rate and ultrasonic scores of the 4 chamber view,outflow tracts and 3 vessels (and trachea)view obtained from TUI and routine ultrasonography for fetal heart screening were respectively compared. Results Among all 110 cases,the visualizing rate of 4 chamber view,outflow tracts and 3 vessels(and trachea) view were respectively 100%(67),88.9%(45),80.0%(45),84.4%(32)in Bmode and 100%(33),86.2%(25),50.0%(14),100%(4)in CDFI under the same fetal Dositi.n.No significant differences of the visualization rate were found between TUI and routine screening either in Bmode or in CDFI(P>0.05). The median score of 4 chamber view of TUI in B-mode was little higher than that in routine screening,while the right outflow tract of screening in CDFI significantly higher than that of TUI(P<0.05). Conclusions The visualizing rates and qualities of TUI are sufficient for fetal heart screening offline as well as routine ultrasonography online in second trimester.

Objective To investigate the clinical therapeutic effect of Xuebijing injection for treatment of patients with diabetic nephropathy(DN)and its mechanism. Methods 60 DN patients were randomly divided into Xuebijing group and control group(each,30 cases). The patients in both groups received western conventional treatment,and the patients in Xuebijing group received additionally Xuebijing injection intra-venous injection once a day for 14 days. The fasting blood glucose(FBG),glycosylated hemoglobin(HbA1c),urinary albumin excretion rate(AER),blood urea nitrogen(BUN),serum creatinine(SCr),hematocrit(HCT),fibrinogen(Fg),whole blood viscosity,total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C)and interleukin -6(IL-6),tumor necrosis factor-α(TNF-α)and urine β2-microglobulin(β2-MG)levels before and after treatment were detected,and the curative effect was also observed in both groups. Results In the control group blood FBG,BUN,SCr,TC,IL-6 and TNF-αafter treatment were significantly decreased and HDL-C significantly increased compared with those before treatment(all P<0.05). Compared with those before treatment,in Xuebijing group after Xuebijing therapy,blood FBG,β2-MG,AER,BUN, SCr,TC,TG,HCT,blood viscosity,IL-6 and TNF-αwere significantly decreased,and HDL-C was obviously increased,but there were no significant differences in HbA1c,LDL-C and Fg before and after treatment. The above indexes were changed significantly in Xuebijing group compared with those in control group〔FBG(μg/L):6.98±1.14 vs. 9.73±1.62,β2-MG(μg/L):32.1±10.9 vs. 57.2±15.1,AER(μg/min):86.0±28.1 vs. 152.0±51.6,BUN (mmol/L):12.4±8.1 vs. 19.5±8.9,SCr(μmol/L):301.2±151.9 vs. 371.3±168.6,HCT:0.283±0.075 vs. 0.351±0.059,TC(mmol/L):3.4±1.8 vs. 4.1±1.5,TG(mmol/L):3.4±1.5 vs. 3.6±1.7,HDL-C(mmol/L):1.90±0.75 vs. 1.50±0.25, IL-6 (ng/L):8.96±2.07 vs. 12.75±2.47, TNF-α(pmol/L):17.85±4.75 vs. 20.87±4.90,P<0.05 or P<0.01〕. The total efficiency in Xuebijing group was significantly higher than that in control group(83.3%vs. 36.7%,P<0.01). Conclusion Xuebijing injection has significant protective effects on patients with DN,and the mechanism might be associated with increasing tissue perfusion and inhibiting excessive inflammatory cytokines release.
