Objective To compare the diagnostic value of myocardial perfusion imaging (MPI) and 64 multi-slice spiral CT (64-MSCT) for coronary artery disease (CAD). Methods Fifty-two patients with suspected or known CAD were included in the study. Each patient underwent both stress and rest MPI,MSCT as well as conventional coronary angiography (CAG) within 1 month. The stress and rest MPI were scored by a 5-grade criteria (0 ～ 4) based on 17 coronary artery segments. The difference between summed stress and rest scores ＞ 1 was defined as myocardial ischemia. Stenosis in one main vessel or one main branch of the main vessel ≥50% was defined as myocardial ischemia by MSCT. CAG was used as the reference for comparison. Statistical analysis was performed using SPSS 13. 0 software. Kappa value was used to test the accordance of MPI and MSCT results. X2 test was used to evaluate the difference between MPI and MSCT results. Results The patient-based sensitivity, specificity, positive and negative predictive values and accuracy of MPI and MSCT for the diagnosis of CAD were 86.7% (26/30), 77.3% ( 17/22),83.9% (26/31), 81.0% ( 17/21), 82.7% (43/52) and 83.3% ( 25/30), 86.4% ( 19/22), 89.3%( 25/28), 79.2% ( 19/24), 84.6% (44/52), respectively. The vessel-based sensitivity, specificity, positive and negative predictive values and accuracy of MPI and MSCT were 74.5% (38/51), 81.0% (85/105 ), 65.5% (38/58), 86.7% ( 85/98), 78.8% ( 123/156 ) and 90.2% (46/51 ), 88.6% ( 93/105 ),79.3 % (46/58), 94.9% (93/98), 89.1% ( 139/156), respectively. There was no statistically significant difference between MPI and MSCT for either patient or lesion-based diagnosis (X2 =0.44, 0.21, both P ＞0.05 ). 96.0% (24/25) patients with both abnormal MPI and MSCT positive were valified by CAG while 83.3% (15/18) patients with both MPI and MSCT negative were excluded by CAG. Conclusions Both MPI and MSCT are reliable diagnostic modalities for CAD. They also provide complementary diagnostic value to each other.

OBJECTIVETo evaluate clinical effect and safety of floating needle therapy and duloxetine in treating patients with persistent somatoform pain disorder (PSPD).

METHODSTotally 108 PSPD patients were randomly assigned to the floating needle treatment group, the duloxetine treatment group, and the placebo treatment group, 36 in each group. Patients in the floating needle treatment group received floating needle therapy and placebo. Those in the duloxetine treatment group received duloxetine and simulated floating needle therapy. Those in the placebo treatment group received the placebo and simulated floating needle therapy. All treatment lasted for six weeks. Efficacy and adverse reactions were evaluated using Simple McGill pain scale (SF-MPQ) and Treatment Emergent Symptom Scale (TESS) before treatment and immediately after treatment, as well as at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Hamilton Depression Scale (HAMD, 17 items), Hamilton Anxiety Scale (HAMA) were assessed before treatment and at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Patients in the floating needle treatment group and the duloxetine treatment group with the total reducing score rate of SF-MPQ in Pain Rating index (PRI) ≥ 50% after 6 weeks' treatment were involved in the follow-up study.

RESULTS(1) Compared with the same group before treatment, SF-MPQ score, HAMD score and HAMA total scores all decreased in all the three groups at the end of 1st, 2nd, 4th, and 6th week of treatment (P < 0.05, P < 0.01). Besides , each item of SF-MPQ significantly decreased immediately after treatment in the floating needle treatment group (P < 0.01). Compared with the placebo treatment group, SF-MPQ, HAMD, and HAMA total score in the floating needle treatment group significantly decreased after 1, 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). SF-MPQ score, HAMD score and HAMA total score in the duloxetine treatment group also significantly decreased after 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). (2) There were 3 patients (8.3%) who had adverse reactions in the floating needle treatment group, 17 (50.0%) in the duloxetine treatment group, and 7 (21.2%) in the placebo treatment group. Compared with the placebo treatment group, the incidence of adverse reaction increased in the duloxetine treatment group (χ² = 6.04, P < 0.05). Besides, it was higher in the duloxetine treatment group than in the floating needle treatment group (χ² = 14.9, P < 0.05). (3) There were 19 patients in the floating needle treatment group and 17 patients in the duloxetine treatment group involved in the follow-up study. Compared with 6 weeks after treatment, no significant difference was observed at 3 and 6 months after treatment in the score of SF-MPQ, HAMD, and HAMA in the floating needle treatment group and the duloxetine treatment group. No significant difference was observed between the two groups (P > 0.05). There were 5 patients (29.4%) who had adverse reactions in the duloxetine treatment group, and no adverse reactions were observed in the floating needle treatment group. The adverse reaction rate was significantly different between the two groups (χ² = 4.26, P < 0.05).

CONCLUSIONSFloating needle therapy and duloxetine were effective in treatment of patients with PSPD. However, floating needle therapy could relieve pain more rapidly than duloxetine, with obviously less adverse reactions.

OBJECTIVE: To access application value of multi-slice spiral computed tomography (MSCT) and coronary artery calcium scoring (CACS) in investigation the coronary artery disease (CAD), and to explore the effective way of virtual autopsy to evaluate the sudden death due to CAD. METHODS: Nine cases of sudden cardiac death were collected to analyze MSCT before the autopsy. The quantitative analysis of the degree of coronary artery calcium was made by Agatston's method. The CACS of all the subjects were calculated based on the diagnostic criteria for CAD, in which calcium scoring was more than 400. The results of CACS were compared with that of the autopsy. RESULTS: Only 2 cases got the high calcium scoring which were more than 400 in the 9 cases died of CAD confirmed by the autopsy. The prediction rate of CACS for CAD was only 22.2%. Pulmonary edema of different severity was found in both autopsy and MSCT. There was a higher morbidity rate in the left anterior descending of coronary artery than the other branches. CONCLUSION Obvious calcification of coronary artery can be detected by MSCT and calculating CACS. To detect subtle calcification needs other technologies such as postmortem angiography.

The transcription factor of ethylene responsive factor binding protein (ERF) is belonged to AP2/ERF superfamily, which is known to be unique in plants. AP2/ERF proteins have important functions in the transcriptional regulation of a variety of biological processes related to growth and development, as well as various responses to environmental stimuli. An ERF gene from Salvia miltiorrhiza is cloned and divided into ERF gene family group VII of Arabidopsis and Rice. It contains a MCGGAI (I/L) motif referred to as CMVII-1 and a single intron in the 5'-flanking region of the AP2/ERF domain. Sequence analysis reveals that the region of second extron has abundant polymorphism sites. There are 21 single nucleotide polymorphism sites (SNPs) in the 264 bp region, among them, 14 SNPs are synonymous substitutions and 7 SNPs are non-synonymous substitutions. Though analysis of 181 samples from Shandong, Shaanxi and Sichuan Provinces, it reveals that each production area has its own special genotypes, 5 SNPs show significant difference. Cluster based on UPGMA method reveals that different populations from specific province have clustered together. It shows that SmERF gene will be a candidate molecular marker for the identification of Salvia miltiorrhiza from different areas.
