Objective To study the inconsistent relation of twin discordancy and the umbilical artery blood flow parameter of systolic/diastolic ratio.Methods 358 pregnant women were divided into the two groups of develop-mental nonidentity( n=67 ) and developmental identity ( n=291 ) according to the criterion that the differences of twins weight exceeded 25 percent.The umbilical artery blood flow parameter of systolic/diastolic ratio were observed. Meanwhile,the difference of weight and the umbilical artery blood flow parameter of systolic/diastolic ratio in the group of developmental nonidentity were observed.Results A significant difference of the umbilical artery blood flow parameter of systolic/diastolic ratio were found in the two groups of developmental nonidentity and developmental identity(7.81%vs 32.56%,P<0.05).There were 56 cases that twins weight exceeded from 25 to 35 percent,7 cases that twins weight exceeded from 35 to 45 percent and 4 cases that twins weight exceeded 45 percent in the group of developmental nonidentity which the umbilical artery blood flow parameter of systolic/diastolic ratio were (23.66 ± 5.78)%,(27.16 ±7.25)% and (33.16 ±4.23)% correspondingly with significant difference(F=23.21,P<0.05 ) .Conclusion The umbilical artery blood flow parameter of systolic/diastolic ratio has significance in diagnosis of twin discordancy.

Brain metastasis ( BM) is a common brain tumor in a-dults, originating from extracranial location in the body. There has been a growing interest in producing suitable animal models for studying BM in vivo. Current BM models take peripheral or brain route for tumor cell inoculation, including intra-cardiac or intra-carotid artery injection or orthotopic injection. Direct im-plantation of patient tumor biopsies into rodent brain bears ad-vantages of clinical relevance. This review presents a compre-hensive introduction to key elements for establishing animal mod-els of BM, with highlights on selections of suitable model ani-mals, brain-seeking tumor cell lines, reasonable inoculation routes, as well as succedent phenotyping methods. In the end, perspectives and future directions in this field are discussed.

Objective To evaluate the effect of biofeedback therapy for the treatment of myogenic fecal incontinence. MethodsA general assessment about anorectal function was made on 17 cases receiving biofeedback therapy including muscle power training,sensory training and coordination training. Results The clinical scores before and after biofeedback therapy were 1.66?0.23,3.80?0.42 respectively,with an effective rate of 82%. The anus maximum contracting pressure elevated,(73?20) mm Hg vs. (123?30) mm Hg; myoelectric amplitude increased,(122?32) ?V vs. (230?41) ?V;Contracting time prolonged,(4.1?2.0) s vs. (9.4?3.0) s; The sensory threshold was lowered,(50?12) ml vs. ( 20? 10) ml;The feel-contract time increased,(3.1?0.4) s vs. (1.2?0.3) s. Positive rectal contraction reflex was seen in 41% patients before therapy compared with 82% after therapy. Conclusions Biofeedback therapy increases contractility of sphincter,decreases threshold of rectal sensory,and is a therapy of choice for myogenic fecal incontinence.

Objective:To investigate the effects of the proportional imbalance of Th1/Th2 in allergic asthma model by transferring the recombinant of PcDNA3.0/p27kip1 eukaryotic expressing plasmid into allergic asthma model.Methods:KM mice were distributed into three groups:healthy control mice(group A);Ovalbumin(OVA)-sensitized/challenged mice(group B) and OVA-sensitized/challenged mice intratracheally administered with PcDNA3.0/p27kip1 plasmid(plasmid-treated mice,group C).KM mice were sensitized and challenged intratracheally with OVA,then transfected with the recombinant PcDNA3.0/p27kip1 eukaryotic expressing plasmid which was constructed by our laboratory crew through vein injection.The p27 protein expression in lungs 36 h after transfection was analyzed by Western blot;Flow cytometry was used to analyze the proportion of CD4 (+)and CD8(+) T lymphocyte subsets in the spleen.The serum levels of IL-4,IL-5,IL-13 and IFN-? were measured by ELISA.Results:Compared to the group A,the expression of p27 protein was significantly reduced,and the proportion of CD4(+)lymphocytes and serum levels of IL-4,IL-5 and IL-13 were significantly higher but CD8(+)lymphocytes and IFN-? was significantly decreased in group B.However,in group C,the expression of p27 protein was significantly increased;Whereas the proportion of CD4 (+) lymphocytes,serum levels of IL-4,IL-5 and IL-13 were significantly decreased.CD8 (+) lymphocytes and IFN-? were significantly increased than those in group B.Conclusion:p27 could be expressed in lungs of plasmid-treated mice and regulate the proportion of Th1/Th2 subset by means of adjusting cell cycles.This method may serve as a potential therapeutic option for the treatment of asthma.

Objective To investigate the effects of interferon-α (IFN-α) and gefitinib on the proliferation and apoptosis of human colon cancer cell line HCT116. Methods Colon cancer cell line HCT116 was selected as research objective. The biological effects of IFN-α and gefitinib alone or combined on the cells were observed at different time point (after worked for 24, 48 and 72 hours). The proliferation inhibition of the medicine on the HCT116 cells was measured by methyl thiazolyl tetrazolium (MTT) assay. Morphologic changes were observed under optical microscope. Apoptosis was measured by flow cytometry (FCM). The results were analyzed with SPSS 13.0 software, two groups compare was tested by t test, and single factor variance analysis was for multiple group data compare. Results IFN-α and gefitinib alone or combined could significantly inhibit the proliferation of HCT116 cells (P<0.05), and there was a time and dose-dependent manner between the degree of inhibition and the working time and concentration of the medicine. With the work of the medicine, apoptosis morphologic changes were observed in the cells. And FCM result indicated that the apoptosis rate significantly increased. After treated with IFN-α and gefitinib alone or combined for 72h, the cell apoptosis rate were 15.6%±0.6%, 13.6%±0.4% and 31.2%±0.3% respectively, which was obviously higher than control group (6.8%±0.3%, P<0.05). Conclusion Both IFN-α and gefitinib were able to inhibit the proliferation and induce apoptosis of HCT116 cells moreover, and a synergistic effect was observed while combine used there two medicines.
