Objective To evaluate the scan technique and clinical value of multi-slice spiral CT angiography(MSCTA) of coronary artery.Methods MSCTA was performed in 86 patients,and 25 of them were also investigated with selective coronary angiography(SCA).The imaging quality of MSCTA in different scanning condition were analyzed.The patency of coronary artery and other branches were examined.The distribution and extent of coronary arterial stenoses were assessed.The findings demonstrated on MSCTA were compared with those seen on SCA.Results(1)The imaging quality on MSCTA of coronary artery was significant better in patients with a heart rate below 60 beats per minute,contrast flowing rate 3.0~3.5 ml/s,volume 120~150 ml and delayed time 22~25 s;(2)in 25 cases,of 71 coronary artery and branches without stenoses examined with MSCTA,68 had identical appearance on both MSCTA and SCA.The distribution and extent of 19 coronary arterial stenoses revealed by MSCTA were correlated exactly with SCA in 29 coronary arterial stenoses.The negative and positive predicted value were 95.8% and 65.5% respectively.Sensitivity,specificity and accuracy were 86.4%,87.2% and 87.0% respectively.Conclusion MSCTA as a noninvasive examination is a valuable method in detecting diseases or variations of coronary artery.

Objective: To validate the clinical value of CT-guided curve-needle percutaneous ethanol injection (CNPEI) for celiac plexus block analgesia. Methods: Thirty-two patients with end-stage cancer, including 13 complicated with extensive retroperitoneal lymph node enlargement and fusion, were enrolled in this study. All patients complained of refractory upper abdominal pain and had received narcotic analgesics and radiotherapy, but the analgesic effect was not good. CT-guided CNPEI was therefore prescribed. Results: The effective rates of CT-guided CNPEI were 100%, 100%, 96.9%, 90.6%, 87.5%, and 84.4% immediately, and at 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 16 weeks after treatment, respectively. All enlarged lymph nodes had obvious necrosis and became shrunk. Conclusion: Combined application of bilateral anterior and posterior diaphragmatic crura block and trans-lymph node block can produce good analgesic effects, and curve-needle puncture make the above technique simpler.

The morbidity of transient hypothyroxinemia of prematurity (THOP) was high. There is controversial about thyroid hormone supplementation in THOP. Clinical studies suggest that thyroid hormone supplementation can reduce the incidence of patent ductus arteriosus,but no effect on the mortality and the incidence of respiratory disease.Thyroid hormone supplementation can improve the neurodevelopmental outcomes in infants with gestational age less than 28 weeks with THOP, but no effect on infants with gestational age more than 28 weeks. Future research should focus on the normal range of thyroid hormone according to gestational age in preterm infants,and randomized clinical trial welldesigned stratified according to gestational age to study the long-term neurodevelopmental outcome of thyroid hormone replacement therapy in infants with THOP

The paper discussed the working platform for medical ethics education,for the purpose of making such education regular,normalized and popular among the staff.Such means as better organization,innovative media,reinforced implementation and repeated examination will encourage hospital staff to develop better medical ethics for better quality of care and elevation of hospital culture and social satisfaction.

Objective To investigate the expression and clinicopathological features of gene associated with retinoid-interferon mortality-19 (GRIM-19) in epithelial ovarian carcinoma.Methods The expression of GRIM-19 gene in tissues from 138 cases of epithelial ovarian carcinoma,102 cases of benign ovarian epithelial tumor and 46 cases of normal ovarian tissues were detected by Immunohistochemistry and Western blot methods.Assembled clinical survival data were analyzed with Kaplan-Meier and Cox regression models.Results The expression level of GRIM-19 in epithelial ovarian carcinoma (3.4 ± 2.0) was lower than that in benign ovarian tumor tissues (4.7 ± 2.9) and that in normal ovarian tissues (7.5 ± 2.2 ; P ＜0.01).The level of GRIM-19 expression was related to the survival time of epithelial ovarian carcinoma patients by Kaplan-Meier analysis (P =0.002).The shorter survival time of epithelial ovarian carcinoma patients was significantly associated with the level of GRIM-19 expression (P =0.001),clinical stage (P =0.001),volume of ascites (P =0.023) and the largest diameter of the primary tumor lesion (P =0.044) by Cox regression models.Conclusions The low expression of GRIM-19 in the epithelial ovarian carcinoma suggests that GRIM-19 may be a key gene involved in its carcinogenesis.The expression level of GRIM-19 may be also an independent prognostic factor for epithelial ovarian carcinoma patients.

Objective To evaluate the role of bispectral index (BIS) in assessing the depth of sedation in hypogastric operation of children. Methods Forty children undergoing hypogastric operation were divided into two groups with 20 cases each by pre-school (age 3-5) (Ⅰ group) and school (age 6-12)(Ⅱ group). Sedation was solely maintained with TCI propofol. The infusion was adjusted till adequate scdation (OAA/S≤ 1 score) before sacral block. The course of propofol infusion and BIS of recovery period were closely observed. Sedation scores were assessed by special anesthetists. Results During recovery period, the mean values of BIS were gradually increased, when BIS > 76 predicted 94% sensitivity and 50% specificity in Ⅰ group, 100% sensitivity and 100% specificity in Ⅱ group. ROC area under the curve of the two groups were 0.917 ± 0.007, 0.955 ± 0.004. Conclusions BIS can predict fairly well the level of consciences during recovering periods. BIS monitoring is an effective and reliable method to guide children recovery.
