ABSTRACT

Objective To investigate the value of transvaginal ultrasound for the diagnosis of endometrial polyps .Methods The ultrasonographic characteristics in 56 cases of endometrial polyp diagnosed by transvaginal ultrasound were performed the retro-spective analysis and the situation of the hysteroscopic examination in consistent with the pathological examination was analyzed . Results Among 56 cases ,50 cases of endometrial polyps were verified by the pathological examination ,the coincidence rate of transvaginal ultrasound diagnosis was 89 .3% ,in which 6 cases were misdiagnosed with the misdiagnosis rate was 10 .7% . Conclusion The transvaginal ultrasound has the high accuracy rate for diagnosing endometrial polyps .

ABSTRACT

Objective To investigate the effects of leonurus heterophyllus injection and oxytocin and their combination applica-tion in treating postpartum hemorrhage .Methods Sixty cases of cesarean section due to the medical factors or the social factors and 54 cases of vaginal delivery were randomly divided into 3 groups by the blind method ,i .e .the leonurus heterophyllus injection group ,the oxytocin group and the leonurus heterophyllus injection plus oxytocin group .Each group was treated by the specific mode .The amounts of intraoperative bleeding and at postpartum 48 h bleeding were recorded ,and the time of the third stage of la-bor was recorded .One way Anova was used to analyze the obtained data .Results The intraoperative bleeding amounts were (1 014 .75 ± 159 .10) mL in the leonurus heterophyllus injection group and the cesarean section group ,(433 .88 ± 75 .34) mL in the leonurus heterophyllus injection plus oxytocin group and (562 .30 ± 102 .00) mL in the oxytocin group ,the difference among the groups were statistically significant(F=67 .48 ,P<0 .01) .The post hoc LSD test showed that under P<0 .05 ,LSD=109 .58 ,indi-cating the significant differences between the two groups ;in the vaginal delivery group ,no statistical difference in the total bleeding amounts ,postpartum 2 h and 2-6 h bleeding amounts had no statistical differences among 3 groups ,but the other time periods of detection had difference ,in which ,compared with the oxytocin group ,postpartum 24 h bleeding amount in the leonurus heterophyl-lus injection group was relatively less ;in the cesarean section group ,the third stage of labor had no statistical difference among 3 kinds of treatment group .Conclusion Using leonurus heterophyllus injection after vaginal delivery can reach the similar effect as oxytocin .However ,leonurus heterophyllus injection is not recommended to be exclusively used in cesarean section .

ABSTRACT

Objective To study the efficacy and safety of transverse compression suture in the lower uterine segment for the control of postpartum haemorrhage in cesarean section caused by placenta previa. Methods From Jan 2011 to Jan 2013, 21 patients with postpartum haemorrhage in cesarean section due to placenta previa were given transverse compression suture in the lower uterine segment after routine medical treatment. And the hemostatic efficacy and safety were observed. Results 20 cases of the vaginal bleeding were controlled efficient-ly, with an efficiency of 95. 2%. There was no complication occurred, and menstruation were back to normal during the follow-up, and there was nothing abnormal in the uterine double accessories through B ultrasound reexamination. Conclusion Transverse compression suture in the lower uterine segment is an easy, safe and highly effective surgical technique, it is especially suitable for the control of haemorrhage in the lower uterine segment caused by placenta previa.

ABSTRACT

Objective To obtain the expression pattern of imprint gene H19 in JEG-3 cell in order to explore the regulation mechanism of H19 on trophoblast cellular biological behavior .Methods After correct identification with sequencing for the recom-binant eukaryotic expression plasmid pRc/CMV which including the whole length of H19 cDNA ,the plasmid was transfected to the cell line JEG-3 .The expression of H19 mRNA was observed and the gene expression profile of three groups of JEG-3 cell were de-tected with Affymetri :U133 plus 2 .0 Array .Results After being transfected with target H 19 gene ,the expression of the mRNA level was significantly increased compared with control group .And the gene expression profile was changed significantly .19 genes were up-regulated ,77 genes were down-regulated .Expression levels of HES1 gene which being choosed as a different expression gene were detected by fluorescence quantitative PCR in severe preeclampsia placenta tissue and normal late pregnant placenta .The expression level of HES1 mRNA in severe preeclampsia placenta decreased significantly than normal late pregnant placenta tissues . Conclusion Many genes induced by H19 have been screened by high-throughput gene chip method .It provides the experimental ba-sis for advanced studying the regulation the cellular biological behavior with H 19 gene .

ABSTRACT

Objective Through observing and treating the ovulation dysfunction patients with birth demand ,to study the clinic characteristics and therapy strategy .Methods 630 clinical cases including natural cycles and controlled ovarian stimulated cycles . monitored by transvaginal B-ultrasonography from April 2008 to April 2012 ,The common reasons ,clinical manifestation ,and out-come undergoing different treatment strategies were analyzed .Results In the natural cycles ,41 .61% patients suffered ovulation dysfunction ,PCOS patients occupied the most .Through the therapy of controlled ovarian stimulating on these patients ,60 .84% of ovulation dysfunction patients recovered normal ovulation .The therapeutic regimen of clomiphene citrate (CC) 50 mg and of CC combined with human menopausal gonadotropin(HMG) showed a higher ovulation rate ,66 .49% and 67 .57% respectively(P<0 .05) .Anovulia was the most commonly type of the ovulation dysfunction ,followed small follicle ovulation and luteinizing unrup-tured follicle .Conclusion Ovulation dysfunction is frequent in infertility patients .Understanding the clinical characteristic and the disease cause ,working out the favourable and effective therapeutic regimen can increase their conception possibility .

ABSTRACT

Objective T9 provide candidate molecules for developing recombinant anti-idiotypic antibody (anti-Id) vaccine of gastric carcinoma by selection of recombinant anti-Id to monoclonal antibody ( McAb) MGb1 directed against the cancer with phage display technique.Methods Balb/c mice were immunized with MGb1 and the mRNA was isolated from the spleens of the immunized mice. The VL and VH cDNAs of the antibody were amplified separately by RT-PCR and assembled into ScFv DNAs with a linker DNA. The ScFv DNAs were ligated into the phagemid vector pCANTAB5E and the ligated sample was transformed into competent E. coli TG1. The transformed cells were infected with M13KO7 helper phage to yield recombinant phage antibody ScFv library. After four rounds of biopanning to the library with MGb1, the MGb1-positive clones were selected from the enriched phages by ELISA. The types of the anti-Id ScFv displayed on the selected phage clones were preliminarily identified by competition ELISA. Results The VL and VH cDNAs was about 320 bp and 340 bp, respectively. The ScFv DNA were about 750 bp. After four rounds panning to the phage antibody ScFv library with MGb1, 18 MGb1-positive phage clones displayed anti-Id ScFv were selected from 50 pre-selected phage clones, among which 4 clones displayed β or γ type anti-Id ScFv. Conclusion The phagedisplayed anti-Id ScFvs to McAb MGb1 are successfully selected by recombinant phage antibody technique, which might lay a foundation for screening the anti-Id ScFv possessing the characteristics of inducing anti-gastric carcinoma immunity.

ABSTRACT

Objective To clone the cDNA encoding human HMGB1, express it in E. coli, and identify its biological activity. Methods Human HMGB1 cDNA was amplified by RT-PCR and cloned into vector pUC19. After sequence analysis, the cDNA was ligated into prokaryotic expression vector pQE-80L and induced by IPTG to express HMGB1. The protein was purified with Ni~(2+)-NTA chromatography and polymyxin B affinity column. To identify the function of purified protein, the product was co-cultured with THP1 cells. Results Recombinant expression plasmid pQE-80L/HMGB1 was constructed successfully. After purification, the protein purity reached 96%. The recombinant HMGB1 stimulated THP1 to secrete TNF-? . Conclusion The highly purified HMGB1 was obtained successfully, which showed biological activity. These results lay the foundation for further research on the function of human HMGB1.
