Objective To explore the significance of ultrasound in choosing the delivery modality in 200 cases scarred uterus gravida′s second deliveries .Methods The study selected 200 cases late pregnancy gravidas who had once uterine incision delivery history and analyzed clinical data retrospectively ,all of them were chosen from September 2010 to September 2013 in our hospital . All cases were taken by transabdominal ultrasound or transvaginal ultrasound firstly ,then taken by transabdomina transvaginal ul‐trasound ,finally contrast obsenved the transabdomina transvaginal ultrasound detections with their caesarean section observations , meanwhile observe how the uterus scar ranking affect the delivery consequence .Results (1)A total of 200 cases had higher uterus scars visualization ratio(100 .0% ) than ransabdominal ultrasound (92 .0% )and transvaginal ultrasound(96 .5% )(P<0 .05);con‐trasting the transabdomina transvaginal ultrasound with the caesarean section observations ,there was no significant difference(P>0 .05) .The grading diagnosis coincidence of transabdomina‐transvaginal ultrasound was 89 .74% .(2)The UD rate ,the bleeding vol‐ume during operation and the 24 hours postoperative bleeding volume of scarred uterus gravida grade Ⅱ and grade Ⅲ were signifi‐cantly higher than grade Ⅰ (P<0 .05) .Conclusion Transabdomina transvaginal ultrasound can effectively improve the diagnosis coincidence rate of uterine scar detection and can help to chose the better delivery mode according to the scars healing .

Objective To investigate the diagnostic value and therapeutic effect of laparoscopy combined with hysteroscopy in patients with tubal infertility.Methods A total of 133 patients with tubal infertility were treated by laparoscopy combined with hysteroscopy in our hospital from September 2004 to December 2007.All the cases were diagnosed by hysterosalpingography(HSG) and hysteroscopy.Results Totally 225 fallopian tubes were examined in the 133 patients,among which 180 tubes were completely occluded,57 were partially occluded,and 18 were patent.After the surgeries,211 tubes wee patent,24 were partially blocked,while 20 were still occluded.The success rate of the operations was 81.4%(193/237).Follow-up was achieved in 92 patients for 4 to 18 months,in the cases,30 were pregnant during the period(pregnancy rate: 32.6%).Of the 30 cases,2 women had tubal pregnancy;22 women were pregnant in 6 months after the treatments,and the other 8 were pregnant in 6-12 months after the operations.In this group of patients,the pregnancy rate in the women with both patent fallopian tubes was 26.1%(24/92),and in those with single patent fallopian tube was 6.5%(6/92).The pregnancy rate in patients with simple tubal infertility was 22.8%(21/92),while that of those who were complicated with tubal diseases was 9.8%(9/92).Conclusion Laparoscopy combined with hysteroscopy can accurately diagnose tubal infertility,and improve the therapeutic effect.

Objective To study the effect of temperature on the emission of tbrmaldehyde trom the blockboard.Methods A 0.25 m3 simulation chamber was used to explore the emission of formaldehyde from blockboard at the temperature of 15,17,19,21, 23,25,27,and 29 ℃,respectively.The relative humidity,the ventilation velocity and the loading factor in simulation chamber was (50?1)%,1.0 L/min,and(1?0.03)m~2/m~3 respectively.Results A hyperbolic logarithm variation in formaldehyde concentration with time in the chamber was observed at different temperatures.Formaldehyde concentration in the chamber increased remarkably once the temperature exceeded 25 C.The chamber stabilization formaldehyde concentration varied with temperature in accordance with an exponent equation of y=0.921 9?0.024 9e~(0.176 4x)(R~2=0.996 9).Conclusion The temperature can greatly influence formaldehyde emission from the blockboards.Higher temperature will facilitate formaldehyde emission from the blockboards.

Objective To investigate the relationship between gliosis, synaptic reorganization and the mechanism of chronic temporal lobe epilepsy induced by kainic acid. Methods The mossy fibers sprouting, synaptic reorganization and gliosis were observed by Neo-Timm staining and immunohistochemical staining respectively. Results The injected (ipslateral) side was injured predominantly in the CA 3 subfield and hilus, whereas the CA 1 subfield was injured mildlyThe contralateral side showed pathological changes mainly in the CA 1 subfield and hilus, and moderately in the CA 3 subfieldThe longer the rats survived, the more obvious changes were observed in the hippocampuses. Conclusion The injection of kainic acid in hippocampus can cause neuronal loss, reactive gliosis and plasticity of neurons, probably form the abnormal neuronal discharge circuit, finally induce the seizures
