Clinical study on therapeutic mechanism of Sini Decoction in treating post-percutaneous transluminal coronary angioplasty ischemia-reperfusion injury in terms of syndrome typing of TCMin treating post-percutaneous transluminal coronary angioplasty ischemia-reperfusion injury in terms of syndrome typing of TCM

Objective: To study the mechanism of Sini Decoction (SND) in prevention and treatment of post-percutaneous transluminal coronary angioplasty (PTCA) ischemia-reperfusion injury with different Syndrome typing of TCM.Methods: Forty patients who received PTCA were randomly divided equally into the SND group and the control group, there were 10 of Excess Syndrome (ES) and 10 of Deficiency Syndrome (DS)in each group. 25 ml SND was given daily to the SND group from 3 days before operation to the third day after operation. The blood Superoxide dismutase (SOD) activity, malondialdehyde (MDA) and nitric oxide (NO) content of patients were determined before PTCA, and 1 hr, 12 hrs, 24 hrs, 48 hrs and 72 hrs after PTCA.Results: Before PTCA, the cases with DS were characterized by low SOD activity and high MDA content, as compared with the patients with ES, P<0.05. SND could relieve the post-PTCA deprivation of SOD activity and NO content and the elevation of MDA level in both ES and DS patients, the amplitude of elevation of SOD activity in DS patients was higher than that in ES patients (P<0.05).Conclusion: SND has antagonizing effect on post-PTCA ischemia-reperfusion injury, which is more effective in treating patients with DS.     

救心复脉注射液治疗心源性休克的临床研究

验证救心复脉注射液治疗心源性休克的临床疗效。方法：用ＣＡ静脉给药治疗心源性休克２０例，用多巴胺注射液作对照。结果；ＣＡ组有效１８例，无效２例，ＤＡ组有效９例，无效２例，组间比较，Ｐ〉０．０５。结论ＣＡ和ＤＡ均能升高血压，增加心泵功能，改善厥脱证的症脉，但ＣＡ比ＤＡ升压速度快，幅度高，作用稳定，对心率有双相调节作用，使心动过速患者心率减慢，使心动过缓患者心率增快。     

Salbutamol or mist in acute bronchiolitis

Abstract Background : The role of bronchodilators in the treatment of bronchiolitis remains controversial.
Methods : A double-blind, placebo controlled trial was performed to evaluate the clinical response to nebulized salbutamol. One hundred and fifty-six infants aged between 7 weeks and 24 months who had had an episode of wheezing and other signs and symptoms of bronchiolitis were randomized to three groups as follows: (i) nebulized salbutamol was administered to 52 patients in group I at a dose of 0.15 mg/kg in 2 mL saline; (ii) saline was nebulized to 52 patients in group II and (iii) in group III 52 patients received mist in a tent. All three groups were administered oxygen during the procedures. Treatment was repeated with the same agent after 30 min if the respiratory score was 5 or more. Respiratory rate, heart rate, oxygen saturation and presence of cyanosis, wheezing, retractions were recorded before and after each treatment.
Results : The decrease in the respiratory score was 5.2 ± 1.8, 0.82 ± 2.4 and 1.7 ± 1.3 in group I, II and III, respectively. The decrease in group I was significantly higher than in the other groups. Heart rate was similar between groups. Oxygen saturation decreased in group I without reaching statistical significance.
Conclusions: Salbutamol was shown to be effective and safe in the treatment of acute bronchiolitis.     

The comparison of dual phase Tc-99m MIBI and Tc-99m MDP scintimammography in the evaluation of breast masses: Preliminary report

The aim of this prospective study was to determine the diagnostic value of Tc-99m MDP scintimammography (SMG) for the detection of breast cancer in patients with breast masses and to compare the results with Tc-99m MIBI scintimammography. Twenty patients, categorized as suspicious, positive or benign for breast cancer according to the mammographic findings were included in the study. Dual phase Tc-99m MIBI and Tc-99m MDP SMG were performed in the prone lateral position within 5 days of each other. Although early and late Tc-99m MIBI SMG showed equal (90.4%) sensitivity, the specificity of late Tc-99m MIBI (87.5%) was found superior to early (62.5%) imaging. The overall sensitivity and specificity of early Tc-99m MDP SMG were 71.4% and 62.5%, respectively. Although late Tc-99m MDP imaging showed 100% specificity, its sensitivity was only 23.8%. In the patients with palpable masses, both early Tc-99m MDP and Tc-99m MIBI showed equal sensitivity (100%), but the sensitivity of early Tc-99m MIBI (37.5%) was found slightly higher than Tc-99m MDP (25.0%) for nonpalpable breast lesions. The sensitivity of Tc-99m MIBI and Tc-99m MDP SMG in detecting metastatic axillary involvement was 66.6% and 50%, respectively. High sensitivity and specificity together with its low cost, easy availability and the possibility of detecting bone metastases seems to make Tc-99m MDP a contributive agent in the evaluation of breast lesions as an alternative to Tc-99m MIBI.

Intraosseous lipoma of the frontal bone. A case report

Intraosseous lipomas are among the most uncommon bone tumors. They arise most often in the appendicular skeleton. There are very few reported cases of intraosseous lipomas within the skull bones. We report a case of intraosseous lipoma of the frontal bone with conventional radiography and CT findings.
