ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effect and safety of Kuanxiong Aerosol (, KA) on patients with angina pectoris.</p><p><b>METHODS</b>Block randomization was performed to randomly allocate 750 patients into KA (376 cases) and control groups (374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA (0.6 mL per spray). The control group received 1 sublingual nitroglycerin tablet (NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment (1, 2, 3, 4, 5, and >5 min). Logistic regression analysis was performed to observe the factors inflfluencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society (CCS) classes of angina.</p><p><b>RESULTS</b>The 5-min remission rates in the KA and control groups were not signifificantly different (94.41% vs. 90.64%, P>0.05). The angina CCS class signifificantly inflfluenced the rate of remission (95% confidence interval = 0.483-0.740, P<0.01). In the CCS subgroup analysis, the 3-and 5-min remission rates for KA and NT were similar in the CCSII and III subgroups (P>0.05), while they were signifificantly better for KA in the CCSI and II subgroups (P<0.05 or P<0.01). Furthermore, the incidence of adverse reactions was signifificantly lower in the KA group than in the control group for the CCSII and III subgroups (9.29% vs. 26.22%, 10.13% vs. 20.88%, P<0.05 or P<0.01).</p><p><b>CONCLUSIONS</b>KA is not inferior to NT in the remission of angina. Furthermore, in CCSII and III patients, KA is superior to NT, with a lower incidence of adverse reactions. (Registration No. ChiCTRIPR-15007204).</p>

Objective To investigate the influence of high intensity interval exercise (HIIT) on peroxidation and vascular endothelial function for experimental hyperhomocysteinemia (HHcy) rats. Methods Thirty five male rats were randomly divided into 4 groups. Control group (n=8) was given ordinary feed. High methionine group (n=27) was given 3% methionine on this basis, and divided into model group, folic acid group and HIIT+ folic acid group, with 9 rats per group for 16 weeks. Serum homocysteine (Hcy) , content of plasma malondialdehyde (MDA) , hydroxyl radical (OH-), total antioxidant capacity (T-AOC), activity of glutathione peroxidase (GSH-PX) and superoxide dismutase (SOD) were measured, as well as the level of Nitric Oxide (NO), Nitric Oxide Synthase (NOS) and Endothelin 1 (ET-1) . The pathology of abdominal aortas was analyzed.Results Sixteen weeks after intervention, there was no significant difference between HIIT + folic acid group and the control group (P>0.05) . The levels of serum Hcy in the model group, folic acid group and the HIIT+folic acid group were (23.95±3.35) μmol/L,(8.73±0.60) μmol/L, and (6.19±0.34) μmol/L respectively (P<0.05) . Sixteen weeks after intervention, the content of MDA in HIIT+ folic acid group reduced, and there was no significant difference compared with the control group (P>0.05). The level of SOD and GSH-PX increased in HIIT+ folic acid group and folic acid group, and there was a significant difference compared with the model group. There were significant differences in activities of SOD and GSH-PX in HIIT+ folic acid group when compared with folic acid group (P<0.05). Compared with the control group, there were significant differences in levels of ET-1, NOS and NO in folic acid group (P<0.05), while there was no significant difference in the level of ET-1 and NOS between HIIT+folic acid group and control group (P>0.05) . Mild atherosclerotic lesions were observed in the HIIT+folic group. Conclusion High methionine diet can reduce the level of serum Hcy in HHcy rats, and high intensity interval exercise combined with folic acid intervention could reduce the level of serum Hcy, improve oxidative stress state, reduce the injury of endothelial function, and thus to alleviate atherosclerotic lesion.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the anginal attack-relieving efficacy and safety of Kuanxiong Aerosol (KA) in patients with coronary heart disease (CHD).</p><p><b>METHODS</b>A total of 780 patients confirmatively diagnosed as CHD angina from November 2011 to December 2012 in 13 medical centers in the mainland area were assigned to 2 groups by blocked randomization, the treatment group (376 cases) and the control group (374 cases). When the angina attacked, patients in the treatment group received sublingual spray three times, 0.6 mL each time, while those in the control group sublingually dissolved Nitroglycerin Tablet (NT), 0.5 mg each tablet. The effective rate of angina relief, efficacy of electrocardiogram (ECG), and the incidence of adverse reactions were observed.</p><p><b>RESULTS</b>The 3 min and 5 min remission rates of angina attack were 53.72% (202/376) and 94.41% (355/376) in the treatment group, and 47.86% (179/374) and 90.64% (339/374) in the control group. The 95% confidence interval (CI) of the difference between the 2 groups of 3 min and 5 min remission rates of angina attacks were [(-1.84%, 12.32%) and (-1.33%, 6.85%) respectively, P > 0.05]. The total improvement rates of ST-T changes in the treatment group and the control group after treatment were 74.07% and 73.13% respectively (P > 0.05). The adverse reaction rate was 9.31 (35/376 cases) in the treatment group and 22.46% (84/374 cases) in the control group (P < 0.01).</p><p><b>CONCLUSION</b>KA was not inferior to NT in relieving anginal attacks and improving ischemic ECG changes, and had obviously less adverse reaction.</p>

<p><b>OBJECTIVE</b>To provide the basis for clinical acquired immunodeficiency syndrome (AIDS) surveillance and to avoid cross infection in hospital, we study the infection status of AIDS in Shandong province.</p><p><b>METHODS</b>The fourth-generated Akzo's ELISA kit and the fourth generated Immunoluminometric detection reagent were used for HIV antibody screening for 399 303 cases of both inpatients and outpatients from Jan. 2003 to Dec. 2011. Beijing WanTai ELISA kit and Se-marked rapid detection reagent were used for re-detection, and the positive samples were sent to the local CDC for confirming test by Western Blot.</p><p><b>RESULTS</b>The HIV-1 antibody detection results of 129 (0. 3230 per thousand) patients were confirmed to be positive, including 54 (0. 1352 per thousand) cases of outpatients and 75 (0. 1878 per thousand) cases of inpatients. HIV infection rates in outpatients from 2003 to 2011 were 0.050 per thousand, 0.030 per thousand, 0.111 per thousand, 0.120 per thousand, 0.124 per thousand, 0.113 per thousand, 0.148 per thousand, 0.201 per thousand, 0.2152 per thousand; and that in inpatients were 0. 150 per thousand, 0.089 per thousand, 0.138 per thousand, 0. 144 per thousand, 0. 104 per thousand, 0. 132 per thousand, 0. 197 per thousand, 0. 329 per thousand, 0. 313 per thousand respectively. Among these inpatients, there were 61 cases of medical patients and 14 cases of surgical patients, and most were youths and farmers.</p><p><b>CONCLUSIONS</b>HIV infection rate was increasing year by year. Most inpatients whose HIV-1 antibody was positive were in the phase of AIDS. Therefore, it's very necessary to execute routine testing for inpatients and outpatients who need special examination for early diagnosis of HIV infection</p>
