Objective To analyze the risk factors in the operative mortality in neonates with congenital heart disease.Methods The surgical outcomes of eongenital heart defects in 231 neonates at Shanghai Children's Medical Center Affiliated to Shanghai Jiaotong University of Medicine,during Jan.2011 and Dec.2013 were detected for retrospectively.Patients were analyzed according to Risk Adjustment for Congenital Heart Surgery-1 (RACHS-1).The age,weight at operation,emergency operation,cardiopulmonary bypass,single ventricle surgery,and RACHS-1 score were detected for risk assessments.Results Overall mortality of congenital heart defect in neonates was 9.96％ (23/231 cases).The top three procedures for high mortality were single ventricle palliative surgery.(25.00％,7/28 cases),corrective operation of interrupted aortic arch (21.43％,3/14 cases),and arterial switch operation with ventricular septum defect repair (13.95％,6/43 cases).There was only 1 case of pulmonary atresia with intact ventricular septum repair,and the case was not classified into high mortality category.With the elevation of RACHS-1,the mortality increased.The mortality rate was 6.67％ (2/30 cases) in RACHS-1 as category 2,6.84％ (8/117 cases) in 3,13.75％ (11/80 cases) in 4,and 50.00％ (2/14 cases) in 6.Multivariable analvsis of risk factors for death showed that single ventricle palliative operation,body weight less than 3 000 g,and RACHS-1 were independent risk factors for mortality.Conclusions This study shows the surgical mortality in neonates with congenital heart defect is still high.Further prospective analysis of specific treatment strategies for high risk patients above was needed and the strategy for single ventricle operation in neonates should be optimized.

Objective To observe the clinical effect of Sangpa Zhike decoction in the treatment of acute exacerbations of chronic bronchitis. Methods 180 patients with acute exacerbation of chronic bronchitis admitted to Autonomous Prefecture Hospital of traditional Chinese medicine(TCM)in Changji,Xinjiang,from August 2012 to August 2013 were enrolled. They were divided into Sangpa Zhike decoction treatment group and western medicine treatment control group by random number table,90 cases in each group. General treatments were given to the two groups. In the Sangpa Zhike decoction treatment group,additionally only oral Sangpa Zhike decoction was given(composition:Morus alba 10 g,loquat leaf 10 g,Houttuynia 10 g,honey aster 15 g,honey coltsfoot flower 6 g,Zhejiang Fritillaria 12 g,perilla 10 g,white mustard seed 6 g,Platycodon grandiflorum 10 g,Rhizoma Cynanchi Stauntonii 12 g,tangerine peel 6 g,Stemona 6 g). The ingredients were mixed in water and boiled to form a decoction,one dose daily,divided into two parts to be taken twice a day. In the western medicine treatment group,the infection was controlled by western medicine and the drugs to eliminate cough and phlegm,etc were used. The therapeutic course in both groups was 7 days. The therapeutic effect for treatment of TCM syndromes and the cough quantized integration score in the two groups were observed after treatment. Results The cure rate of Sangpa Zhike decoction treatment group was significantly higher than that of western medicine treatment control group〔70.00%(63/90)vs. 33.33%(30/90),P<0.01〕. Before treatment,the cough symptom quantization integral scores in the two groups had no statistically significance, but after treatment,the scores in the two groups were significantly lower than those before treatment. And the score in Sangpa Zhike decoction treatment group was decreased more significantly (1.66±1.12 vs. 4.36±2.32, P<0.01). Conclusion Sangpa Zhike Decoction has obvious curative effect in the treatment of acute attack of chronic bronchitis.

Objective:To study the expression of D-amino acid oxidase(DAO) in gastric cancer cells and gastric mucosa cells. Methods:The expression of DAO was detected in seven gastric cancer cell lines and a normal gastric mucosa cell line GES-1 by real-time quantitative PCR and in tumor tissues and normal gastric mucous tissues of 46 patients with gastric cancer by RT-PCR.The liver and kidney tissues of nude mouse acted as positive controls.Results:DAO was expressed in the liver and kidney tissues of nude mouse,and DAO expression in kidney tissue was higher than that in liver tissue.DAO was not detected in seven gastric cancer cell lines and the normal gastric mucosa cell line GES-1.Except one tumor tissue sample,DAO was not detected in other gastric cancer tissues and all normal mucosa tissues.Conclusion:DAO was not expressed in gastric cancer cells and gastric mucosa cells.The nutritional treatment of D-Met in place of L-Met could avoid the disadvantage of methionine starvation to important organs,such as liver and kidney.

OBJECTIVE: To develop an on-line system for the measurement of blood viscosity and hematocrit. The dynamic changes of the macrovascular blood volumes, microvascular blood volumes and the total blood volume were observed by means of calculating from the testing result. METHODS: Applying traditional viscosity measurement principle and specific wavelength optic density measurement method, an on-line system for the measurement of blood viscosity and hematocrit was developed, and the A/D multifunctional board and the testing circuit were designed by ourselves. The system was validated by experiments both in vitro and in vivo. Therapeutic effects of hypertonic saline dextran solution (HSD) and Lactatic Ringer's solution at the early stage after burn-blast combined injury were compared by this method. RESULTS: The results showed that the system has attained the goal of the design. The changes of the blood viscosity and hematocrit could be detected effectively and continuously. The changes of macrovascular, microvascular and total blood volume could be calculated approximately. CONCLUSIONS: The system and the method can continuously on-line test the blood viscosity and hematocrit, and reveal the change and distribution of blood volumes more accurately and clearly in the therapy process by estimating changes of the macrovascular, microvascular and total blood volumes, respectively. It has confirmed that HSD treatment could increase blood pressure and attenuate tissue edema by significantly increasing total blood volume, improving macrocirculatory and microcirculatory blood volumes. This study suggested that it could be desirable to develop an experiment technique based on the method mentioned above.

Objective To determine whether hybrid three dimensional diffusion tensor imaging (3D DTI) contributes incremental value to standard T2WI technique for assessing neurovascular bundles (NVB) around the prostate. Methods This retrospective institutional review board-approved study included 69 consecutive patients with prostate tumor who underwent MRI including conventional T2WI and 3D DTI . DTI data were postprocessed and hybrid 3D DTI and axial T2W images were obtained. Three radiologists with one, five and thirteen years of experience in reading prostate MRI and one urologist with three years of surgical experience in urology who were blinded to patient data independently recorded their levels of preference on a five-point scale of the NVBs around the prostate on the basis of T2WI alone and hybrid 3D DTI and T2WI, respectively. The differences of scores of T2WI and hybrid 3D DTI and T2WI of the four doctors were compared by using nonparametric Wilcoxon rank. Results The average scores of hybrid 3D DTI to T2WI and alone T2WI to assess NVBs for 3 radiologists and one urologist were 4.4±0.6, 4.3±0.8, 4.2± 0.6, 4.9±0.3 and 2.9±0.8, 3.0±1.1, 1.6±0.7, 3.8±0.5, respectively. The hybird 3D DTI to T2WI improved the discrimination abilities of NVBs around the prostate for 3 radiologists and one urologist (Z values were-12.791,-9.737,-14.538,-14.901, P<0.01 respectively).The added value of hybrid DTI to T2WI for urologist is the highest, and experienced radiologist is the smallest. Conclusion The hybrid 3D DTI
contributes significant incremental value to the standard T2WI technique for assessing NVB around the prostate.

Prostaglandin E2 (PGE2) is a bioactive polyunsaturated fatty acid produced by arachidonic acid, and it is mainly metabolized in the liver and has an important regulatory effect on various liver diseases. Prostaglandin E synthases (PGESs) are important terminal rate-limiting enzymes in the PGE2 synthesis pathway and are involved in the development and progression of liver disease. This article mainly summarizes the role of PGESs in liver injury, hepatitis, and liver cancer in existing studies, hoping to provide a reference for further research on the role of PGESs in liver diseases.
