Methods: The focal cerebral ischemia of rats was made by electric coagulation with middle cerebral artery (MCA). The score of ethology, the area of cerbral infarction, AngI, AngII in plasma, C-reactive protein (CRP) in serum, and NF-κB expression were examined to observe the effect of these five Chinese patent medicines by ig administration of Tongsaimai Tablet (0.239 g/kg), Tongxinluo Capsula (0.281 g/kg), Buchang Naoxintong Capsula (0.432 g/kg), Fufang Xueshuantong Capsula (0.405 g/kg), and Xuesaitong Capsula (0.027 g/kg) twice a day for 3 d. Results: Every group of the five Chinese patent medicines could significantly reduce the area of cerebral infarction and the expression of NF-κB. The score of ethology was more lower with Xuesaitong Capsula. The content of IL-6 in plasma was cut down greatly by Tongxinluo Capsula, Buchang Naoxintong Capsula, Xuesaitong Capsula, and Tongsaimai Tablet. The content of CRP in serum was reduced with Xuesaitong Capsula and Buchang Naoxintong Capsula. The content of AngII in plasma was degraded by Tongsaimai Tablet (P<0.05, 0.01). Conclusion: Every Chinese patent medicine can inhibit the release of inflammatory factor at varying degrees. These five Chinese patent medicines can degrade the expression of NF-κB so as to ameliorate cerebral ischemia, and Tongsaimai Tablet can cut down the content of AngII in plasma to lessen the symptom of cerebral ischemia.

ObjectiveTo investigate the value of high-frequency ultrasound in assessment of the therapeutic efifcacy of traditional Chinese medicine in patients with breast dysplasia using.MethodsFrom March to September in 2014, 50 patients with breast dysplasia in the Third Affiliated Hospital of Beijing University of Chinese Medicine were enrolled in the study. In addition, they were treated with Xiaozheng pills. Before and after treatment, these patients were examined using ultrasound. The thickness of the breast gland layer in each patient was measured. When the dilated ducts lactiferous, cysts, hypoechoic areas, or nodules of the breast were detected, the diameter or volume was measured or calculated. A grading system of the breast dysplasia was used to evaluate the disease degree, and the quadrants of the breast dysplasia were counted. The thickness of the breast gland layer, the volume of cysts and nodules, the diameter of hypoechoic areas and the dilated ducts lactiferous, the number of the breast dysplasia were compared with the pairedt-test. The grading of the breast dysplasia was compared with rank sum test.ResultsThere were significant decreases in the thickness of the grand layer, the diameters of the ducts lactiferous and the hypoechoic area after treatments [(15.92±4.73) mm vs(13.02±4.20) mm,t=2.240,P<0.01; (2.26±0.58) mm vs (1.71±0.47) mm,t=5.202,P<0.01; (21.14±5.57) mm vs(17.80±4.63) mm,t=5.529,P<0.01]. However, there were no significant differences in the volume of cysts and nodules. The grading of the breast dysplasia showed statistical difference (z=-5.667,P<0.01), and the number of the breast dysplasia quadrants was reduced markedly (5.38±1.85 vs3.28±1.97,t=7.566,P<0.01).ConclusionsUltrasound can be an effective method in assessment of patients with breast dysplasia treated with the traditional Chinese medicine. The assessment can be based on some signs, including the thickness of the grand layer, the diameters of the ducts lactiferous, and the diameters of the hypoechoic area. The grading system and breast quadrants counting in these patients may be added as supplementary criteria to make a complete therapeutic evaluation.

Objective: To investigate the influence of sufentanil on calcium-activated K+ channels (IKCa) in rat abdominal aortic smooth muscle cells, and to investigate its role in dilation of blood vessels. Methods: Rat abdominal aortic smooth muscle cells (AASMCs) were freshly obtained by enzymatic digestion. Whole-cell voltage-clamp technique was used to assess the effect of sufentanil (1 × 10-8, 3 × 10-8, 1 × 10-7 mol/L) on IKCa. Results: Sufentanil significantly increased the amplitude of IKc compared with the control group (P < 0.05 or P < 0.01). The effect of sufentanil was reversible and in a concentration-dependent manner. Conclusion: Sufentanil can promote the activation of KCa channel in rat AASMCs, which might be related to the vasodilatory effect of sufentanil observed in clinical practice.
