Objective: To observe the clinical efficacy of electroacupuncture (EA) plus long-snake moxibustion for rheumatoid arthritis (RA) due to kidney deficiency and cold coagulation. Methods: A total of 60 patients in active stage of RA were randomly divided into an observation group and a control group, with 30 cases in each group. Patients in the control group took methotrexate tablets and nimesulide dispersible tablets orally for treatment, while those in the observation group received additional treatment of EA plus long-snake moxibustion. Both groups were treated for 12 weeks. The post-treatment changes in symptomatic grading and quantifying score, disease activity score with 28 joint counts (DAS28), and inflammatory indicators erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were observed, and the efficacy was evaluated. Results: The total effective rate in the observation group was 89.9%, versus 76.6% in the control group, and there was a significant difference in the total effective rate between the two groups (P<0.05). After treatment, the symptomatic grading and quantifying score and DAS28 in both groups were significantly improved (all P<0.05), and the improvements in the observation group were more significant than those in the control group (both P<0.05). Besides, there were 11 cases with low disease activity index (DAI) and in remission in the observation group versus 5 cases in the control group, showing a statistically significant between-group difference (P<0.05). The ESR and CRP scores in both groups were significantly reduced after treatment (all P<0.05), also showing statistically significant between-group differences (both P<0.05). Conclusion: The efficacy of additional EA plus long-snake moxibustion based on oral medications for RA due to kidney deficiency and cold coagulation is better than that of the oral medications alone.

Objective: To quantitatively study the incidental extra-cardiac ifndings (ECFs) by coronary computed tomography angiography (CCTA) in patients with suspected coronary artery disease (CAD) in order to better recognize those lesions in clinical practice.
Methods: A total of 1169 suspected CAD patients received CCTA in our hospital from 2011-06 to 2013-03 and 1030 patients were enrolled in this study. There were 589 in-patients, 441 out-patients and 549 patients≥60 years of age,481 patients < 60 years of age. 3 physicians evaluated the incidental ECFs in the full ifeld of view (FOV) in different window level and window width for lung, mediastinum, thorax and upper abdominal areas. Clinical relevance of ECFs were classiifed by corresponding scores. Score 1, the patients with severe lesion need immediate treatment, score 2, the lesion with clinical and prognostic signiifcance and score 3, the ifnding without clinical signiifcance.
Results: There were 197/1030 (19.1%) patients having 224 ECFs and 27 (2.6%) patients having 2 ECFs; 90/1030 (8.7%) patients having 106 signiifcant lesions including 3 (0.3%) of lung cancer and 8 (0.8%) of pulmonary embolism; 107 patients with 118 lesions without signiifcance. ECFs were found in 114/589 (19.4%) in-patients and in 83/441 (18.8%) out-patients, P>0.05; 76/481 (15.8%) of patients < 60 years of age and 121/549 (22.0%) of patients≥60 years,P<0.05.
Conclusion: Unexpected ECFs detection rate was 19.1% in patients undergoing CCTA without further radiation exposure by reconstruction with the full FOV setting, and 8.7% of ECFs had clinical signiifcance. Radiologists should routinely analyze the extra-cardiac organs in CCTA.

To obtain chemical constituent information of rat plasma after oral administration of Huang-Lian-Jie-Du Decoction (HLJDD), a LC-FT-ICR-MS method has been established, and both positive and negative ions scan modes were include in the analysis. By comparing their retention time, high resolution mass data of HLJDD extracts, blank plasma and dosed plasma, 38 constituents, including 22 prototype compounds and 16 metabolites, were detected in rat plasma after oral administration of HLJDD. In the 22 prototype compounds, 16 constituents were determined unambiguously by comparing with references. In the analysis of metabolites, phase II reactions like glucuronidation and sulfation were the major biotransformation pathways of HLJDD. M11 was observed as the only phase I metabolite in present experiment. The results will be beneficial for the further pharmacokinetics and pharmacological evaluations of HLJDD.
