Objective To investigate the association between chest ST segment descent in patients with acute inferior myocardial infarction (AIMI) and myocardial infarction in other area, QT dispersion, severe auriculoventricular block (AVB) serious ventricular arrhythmia. Methods According to persistent time of chest lead ST segment descent,74 patients of acute inferior myocardial infarction with chest lead ST segment descent were divided into 2 groups: ≥24 h (group Ⅰ ,44 cases), ＜ 24 h (group Ⅱ ,30 cases). The occurrence of other areas of myocardial infarction, QTd, auricular-ventricular block and serious ventricular arrhythmia were compared between the two groups. Results Chest ST segment descent occurred in 33 cases in group Ⅰ (75%) ,in 7 cases in group Ⅱ ( 23% ), with significantly difference between the two groups ( χ2 = 19. 17, P ＜ 0. 01 ). QTd was (74. 77 ± 23.28) ms in group Ⅰ which was significantly higher than that of (50. 00 ± 11:45 ) ms in group Ⅱ ( t =5.39,P ＜0. 01 ). Auricular-ventricular block (grade Ⅱ and Ⅲ ) occurred in 20 cases in group Ⅰ (45%),and in 5 cases in group Ⅱ ( 17% ), with significant difference between the two groups (χ2 = 9.43, P ＜ 0. 05 ). Twentyone cases with serious ventricular arrhythmia occurred in group Ⅰ (48%) ,which was significantly higher than that in group Ⅱ (4 cases, 13% ) ( χ2 = 6. 61, P ＜ 0. 01 ) . Conclusion When persistent time of acute inferior myocardial infarction with chest lead ST segment descent is longer than 24 hrs, the area of myocardial infarction is more extensive, QT dispersion increases, the occurrence of serious ventricular arrhythmia and auricularventricular block also significantly increase.

Objective To evaluate the effectiveness of moderate aerobic exercise intervention for patients with Alzheimer's disease. Methods Randomized Clinical Trials(RCTs) that assessed the effectiveness of aerobic exercise intervention for patients with Alzheimer's disease were reviewed using multiple electronic databases systematically. Data were analyzed by RevMan 5.2.0 version. Results Eight RCTs were included. Meta-analysis indicated that moderate aerobic exercise could improve the score of MMSE(WMD=1.58,95%CI:0.63~2.53,P<0.01),reduce the score of Alzheimer's disease assessment scale-cognitive subscale(ADAS-Cog)(WMD=-4.06,95%CI:-6.83~-1.28,P<0.01) and the score of Neuropsychiatric Inventory(WMD=-3.97,95%CI:-5.69~-2.25,P<0.01). Conclusion Moderate Aer-obic exercise can improve cognitive function of Alzheimer's patients,and improve their neuropsychiatric symptoms.

Objective To study the antitumor effects of Scutellaria Radix extracts on H22 transplanted tumor in mice and its possible mechanism.Methods The H22 transplanted mouse models were established by inoculating H22 to mice. 60 mice were randomly divided into model group, 5-Fu group, low-, medium- and high-dose Scutellaria Radix extracts groups, with 12 normal mice as control group. All administration groups received gavage with relevant medicine. And then the body weight change, tumor growth inhibitory rate, and spleen and thymus indexes were calculated;the T-AOC and activities of SOD, and MDA content in serum were detected by spectrophotometer;DNA damage of peripheral blood lymphocytes was observed by single cell gel electrophoresis.Results Medium- and high-dose Scutellaria Radix extracts can significantly inhibit the growth of transplanted tumor. Compared with 5-Fu group, medium- and high-dose Scutellaria Radix extracts groups notably increased the body weight, spleen and thymus indexes of mice, promoted T-AOC and activities of SOD, and decreased MDA content in serum, as well as notably reduced DNA damage of peripheral blood lymphocytes.Conclusion Scutellaria Radix extracts have obvious antitumor effects on H22 transplanted tumor in mice and the possible mechanisms may be due to lightening the damage of normal tissue and cell from tumor, enhancing immunologic function and improving antioxidant capability of H22 bearing mice.

Objective To explore liver protective effects of the stems and leaves and roots of Scutellariae Radix from different areas of Gansu Province;To discuss differences in liver protection of the stems and leaves and roots of Scutellariae Radix. Methods All Kunming mice were randomly divided into 11 groups:normal group, model group, positive control group, Scutellariae Radix root groups and Scutellariae Radix stem-leaf groups of Longxi, Minxian, Weiyuan, Zhangxian. The mice received gavage with relevant medicine once a day for 7 days. 2 hours after the last medication, the mice were given peritoneal injection with 0.1%CCl4 and olive oil to establish the models with liver injury. Hepatic index, the activity of serum ALT and AST, the levels of T-AOC in the liver tissue were calculated in 18 hours after establishing the models. Results Compared with the model group, hepatic index, the activity of serum ALT and AST in the mice of Scutellariae Radix root groups from difference producing areas decreased significantly (P<0.05);the levels of T-AOC in the liver tissue was raised notably (P<0.05). Compared with stem-leaf groups from the same producing area, hepatic index, the activity of ALT and AST in the mice of Scutellariae Radix root groups were remarkably lower than these of Scutellariae Radix stem-leaf groups (P<0.05);the levels of T-AOC in the liver tissue was evidently higher than that of Scutellariae Radix stem-leaf group (P<0.05). Conclusion Scutellariae Radix root water decoction can prevent and protect CCl4-induced acute liver injury to a certain degree, while Scutellariae Radix stem-leaf water decoction shows no significant protective effect on acute liver injury.
