209 Prognostic Value of Doppler Sonography for Ventricular Septal Defect in the 19~24 Weeks Gestation
FAN Qiyun,YU Yimin,WU Yingheng,et al
【Objective】To investigate the prognostic value of Doppler sonography for the ventricular septal defect(VSD) in the 1924 weeks gestation. 【Methods】 A singlecentre prospective observational study was conducted.The pregnant women who underwent the prenatal examination in our hospital from December 2012 to January 2015 were enrolled and were divided into the VSD group(217 cases) and the control group (3535 cases) according to the prenatal ultrasound diagnosis examination at any time and followup within one year of diagnosis results. Fetal hemodynamics of the two groups of pregnant 19 to 24 weeks were recorded and compared : umbilical artery pulsatility index (UAPI) ; middle cerebral artery pulsatility index (MCAPI), middle cerebral artery resistance index( MCARI); splenic artery pulsatility index PI (SPAPI), splenic artery resistance index (SPA RI), splenic artery peak systolic velocity (SpAPSV); brain / umbilical pulsatility index ratio (MCA/UAPI )and brain / umbilical vascular resistance index ratio (MCA/UARI). 【Results】 Fetal UAPI (1.31 ± 0.54), UARI (0.77±0.33) of the VSD group were significantly higher than those the control group (1.09 ±0.33 and 0.68 ± 0.23) (P<0.05), MCAPI (1.48 ± 0.24), MCA/UAPI (1.12 ± 0.29), MCA/UARI (0.99 ±0.18) were significantly lower than those of the control group (1.61 ±0.33, 1.38 ± 0.33 and 1.11 ± 0.20) (P<0.05), but no statistically significant difference exist in MCARI, SpA, PI, SpA, RI, SpAPSV between the two groups (P>0.05). Logistic regression analysis showed that the increase of UAPI (OR=6.314, 95% CI: 240 ~ 24.803) and the decrease of MCAPI (OR=5.887, 95% CI: 1.078 to 13.637) and MCA/UAPI (OR=11.283, 95% CI: 1.597 ~ 106.442) were independent risk factors for prediction of VSD.【Conclusion】At 19 to 24 weeks, the increase of UAPI and the decrease MCAPI and MCA/UAPI are useful marker to predict the occurrence of fetal VSD.

AI Xiuqing,JIA Zhiying,ZHANG Yinghua,et al
【Objective】To investigate the effects of Survivin, HER2, and p53 to predict the effect of neoadjuvant chemotherapy on advancedstage breast cancer. 【Methods】The 120 patients with advancedstage breast cancer and who had received neoadjuvant chemotherapy in our hospital from 2013 January to 2015 January were recruited as subjects. The expression changes and its relations to each factor were analyzed before and after chemotherapy. 【Results】 There were no differences in each factors expression before and after chemotherapy. The positive expression of Survivin and HER2 after chemotherapy were significantly lower than those of before chemotherapy (P<0.05), but the difference in p53 was not statistically significant(P>0.05). The Survivin and HER2 before chemotherapy showed positive correlation to each other but not to p53 before chemotherapy; the Survivin and HER2 showed positive correlation after chemotherapy. 【Conclusion】Survivin ,HER2, and p53 can not predict the effect of neoadjuvant chemotherapy on advancedstage breast cancer, but they can be the targets for evaluating the chemotherapy effect.

216 Research of the Mortality in Emergency Department Sepsis Score for Emergency Department Patients with Sepsis
LIU Xu,LV Juan,LI Wenqiang
【Objective】To research the value of mortality in emergency department sepsis score (MEDS) in emergency department patients with sepsis. 【Methods】The 316 patients with sepsis were eligible for research and collected from March, 2013 to September, 2015. MEDS score, acute physiology, chronic health evaluation Ⅱ (APACHE Ⅱ) score, and arterial blood lactate were tested and the outcomes in 28 days were recorded. According to the sepsis score, all patients were divided into 5 mortality risk groups, namely very low risk group (0~4 points), low risk group (5~7 points), moderate risk group (8~12 points), high risk group (13~15points), and very high risk group (more than 15 points). The mortality rates were compared in five groups and then all patients were divided into survivors and nonsurvivors. MEDS score, APACHE Ⅱ score, and arterial blood lactate were compared. Receiver operating characteristic curve (ROC curve) was used to test the value of prediction between APACHE Ⅱ score, MEDS score, and arterial blood lactate. 【Results】Twentyfour patients were out of the followup and 292 patients were followed up completely among 316 patients. The actual mortality rates of very low risk group, low risk group, moderate risk group, high risk group and very high risk group were 0%, 11.4%, 19.2%, 47.1%, and 67.7%, respectively. Significant differences were observed in age, the level of arterial blood lactate, MEDS score, and APACHE Ⅱ score between survivors and nonsurvivors (P<0.05), but not in hospital time. MEDS score, APACHE Ⅱ score, and arterial blood lactate were valid and eligible for predicating the risk of mortality in patients with sepsis by using ROC curve. ROC squares of the three factors were 0.807, 0.713, and 0.730, respectively. 【Conclusion】 The sepsis score could be used to patients with sepsis and MEDS and was better for predicting 28 days mortality in Emergency department.

FENG Shunhua,HAN Chao,XU Lu,et al
【Objective】To evaluate the effects of dexmedetomidine on hemodynamics and recovery quality for patients undergoing intracranial aneurysms embolism under general anesthesia. 【Methods】40 adult patients with ASA class Ⅰ~Ⅱ for aneurysm embolization were divided randomly into two groups (n=20). All patients were anesthetized with the same scheme of induction and maintenance. The patients in group treated with dexmedetomidine received intravenously bolus dexmedetomidine 0.6 g/(kg•10min) 15 min prior to anesthesia followed by 0.4 g/(kg•h) during the operation. The patients in the saline group received the same dose of saline. HR and MAP were recorded preinfusion, 10 min after infusion, postintubation, end of the surgery, preextubation, immediately after extubation, 5 min after, and 10 min after. Waking time, extubation time, restless and cough score were observed and recorded. Sedation scores were evaluated and recorded with the Ramsay score after 10 min of extubation. 【Results】The operation time, waking, and extubation time were no different between both groups (P>0.05). MAP and HR were significantly lower in patients of group dexmedetomidine than patients in group saline at the time of intubation and preextubation, extubation and 5 min after extubation (P< 0.05). Ramsay sedation scores were higher in patients of the dexmedetomidine group than in patients of group saline at the time of 10 min after extubation, and cough score, agitation score were significantly lower in patients of group dexmedetomidine than patients of group saline (P<0.05). 【Conclusion】It is helpful to stabilize hemodynamics and improve recovery quality when the patients undergoing intracranial aneurysms embolism are administered dexmeditomidine intravenously with bolus 0.6 g/(kg•10min) and followed by 0.4 g/(kg•h). 

226 Analysis of the Postoperative Hypopituitarism in Pituitary Adenomas after Endoscopic TransSphenoidal Microsurgery
NI Shihui,BI ChangLong,YANG Yichun,et al
【Objective】 To investigate the change in the hormonal level of the pituitary adenomas resected by the endoscopic transsphenoidal microsurgery, to evaluate the postoperative damaging factors of pituitary function, and to guide hormonal replacement therapy. 【Methods】We retrospectively analyzed the clinical data and therapeutic methods of 82 cases of obtained pituitary adenomas. The determinations of the hormonal level preoperative and 3d postoperative were detected. These results suggested hypopituitarism and were statistically analyzed. 【Results】The pituitary hormone levels, including thyroid hormone, corticosteroid, and prolactin, were lower 3 days postoperatively in all patients (P<0.05). Hypopituitarism was found in 34 cases and accounted for 41.4% of the total 82 patients, including 2 cases of microadenomas (12 cases, 2.4%), 22 cases of macroadenomas and giant adenomas (70 cases, 16.7%), and 16 cases of nonfunctional adenomas (45 cases, 35.5%). Results showed that decreased function or hypopituitarism before operation was more commonly found in elder patients.【Conclusion】The surgical operation could effectively reduce the hormonal level for pituitary adenomas. The ratio of hypopituitarism postoperatively is wellrelated to tumor volume. Hypopituitarism postoperation is more likely to occur in elder patients or cases which had hypopituitarism before operation or nonfunctional adenomas. Reasonable hormone replacement therapy for patient's recovery is necessary.
