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 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.

Clinicians,as the finders of clinical problems,the refiners of scientific questions and the cooperators of basic and clinic research,play key roles in translational medicine.Clinicians' playing an important part in the process will give the promotion of both the development of translational medicine and improvement of the health condition of the people.

Objective To study the changes of cerebral blood flow and cerebral oxygenation during selective head cooling (SHC) in neonates with hypoxic-ischemic brain damage (HIBD). Methods Thirty-eight neonates with moderate and severe HIBD were enrolled in two groups: SHC group (n=18) and normal temperature group (n=20). The gestational age of all subjects were more than 38 weeks and Apgar score in 5 minutes after birth was less than 5 scores. Also, nerve system symptoms and electroencephalogram abnormal was found in 6 hours after birth. Neonates in SHC group had nasopharyngeal temperature maintained 34℃ and in normal trmerature guoup had rectum temperature maintained about 36℃. Seven healthy neonates were as control group. Three groups were observed 84 h. Cerebral blood flow velocity (CBFV) of middle cerebral artery (MCA) was measured with transcranial Doppler (TCD) at 6, 12, 24, 48, 72 and 84 hours after birth. Cerebral cytochrome aa3 (Cytaa3 ) was monitored continuously throughout the study using near infrared spectroscopy (NIRS). Results At 6th hours after birth, Vs [(25. 05?7. 69)cm/s]、Vd [(7. 22?3. 01) cm/s] and Vm [(15. 61?5. 97) cm/s] of MCA and △Cytaa3 in SHC group were lower, and RI (0. 81?0. 15) was higher than control group (P

Objective:To compare efficacy of percutaneous vertebroplasty (PVP) with radiotherapy and radiotherapy alone for bone me-tastasis pain. Methods:A total of 247 bone metastasis patients with pain were analyzed. The radiotherapy group comprised 158 cases, whereas the combination group comprised 89 cases. We mainly observed the effect of pain treatment, behavioral states, and im-proved emotional condition. The side effects and complications were also investigated. Daily medicine consumption of background pain treatment was observed between the two groups. Analysis was done by SPSS 17.0 statistical software. Numerical variables were analyzed using t test and comparisons between groups used chi-square test. Results:The VAS scores of radiotherapy group decreased from 8.12±1.45 to 3.06±1.68 after treatment (P<0.05), and combination group VAS scores from 8.46±1.73 to 2.45±1.47 (P<0.05). The time to pain relief following PVP and radiotherapy were 1.63±0.81 and 8.56±2.87 days, respectively (P<0.001). The breakthrough pain frequency was 4.56 ± 1.98 times/day, which decreased to 1.57 ± 0.98 times/day after PVP (P<0.05). By contrast, the breakthrough pain frequency was 4.73±2.24 times/day before treatment, which decreased to 3.56±1.56 times/day after radiotherapy. No serious compli-cations were observed in the two groups. The depression and anxiety mood in the combination group improved after treatment. Daily medicine consumption in radiotherapy group increased after therapy. However, daily medicine consumption in combination group was reduced after therapy. Conclusion:PVP with radiotherapy can effectively relieve bone metastasis pain and improve patients' quality of life and it is worthy of promotion in clinical practice.

Objective:To detect depression in stroke patients and observe its influence on rehabilitation of neurological function and the effect of fluxetine therapy Methods:132 acute stroke patients (78 with infarction, 54 with hemorrhage) were included in the study After inclusion, we did five times of assessments at the end of 2 weeks, 1 month, 3 months, 6 months and 1 year respectively using HAMD assessment to determine whether there had depression or not, as well as SSS (modified Edingburgh-Scandinavian Scoring Scale) for neurological function, ADL (activity of daily living), and self rate depression and anxiety (Zung's self rate depression scale and anxiety scale) Of those with depression, 25 received fluxetine 20mg/d, other 32 with only regular treatment of stroke as control Results:According to results of HAMD, 59 of the 132 had depression (44 7%) The rate of depression had no significant difference between male and female, between those with infarction and with hemorrhage Depression had negative influence on neurological function and activity of daily living Depression had no relation to location, size and unilateral or bilateral of the loci Fluxetine improved depression, neurological function and activity of daily living from 3 months after stroke; its influence on neurological impairment was most significant at 1 year after stroke Conclusion: Post stroke depression is common after cerebral infarction or hemorrhage, it has negative influence on rehabilitation of neurological function and activity of daily living Fluxetine improves both neurological impairments and activity of daily function, as the same time of its improvement of depression
