A mine ventilation system has a deterministic function for the safety of coal production and for the control of mine accidents. So, it has an important meaning to evaluate the security of a mine ventilation system. This paper studied the evaluation index system of the security of a mine ventilation system, and the security of a mine ventilation system was described quantitatively in the safety degree. Finally, an example of the security evaluation was given.

Safety of ivabradine, a heart rate lowering drug: a systematic review and meta-analysis

As a novel heart rate lowing agent, ivabradine can reduce the heart rate by inhibiting the If （pacemaker） current in the sinoatrial node without affecting blood pressure or left ventricular systolic function. However, the safety of ivabradine remains controversial. In the present work, we aimed to assess any risk of cardiovascular mortality, bradycardia, phosphenes and atrial fibrillation associated with the ivabradine administration by recta-analysis. Studies were retrieved from PubMed, EMBASE, MEDLINE, Web of Science, Cochrane, www.clinicaltrials.gov web site and related conferences. Randomized controlled trials comparing ivabradine with comparators were identified and analyzed. Two reviewers independently extracted relevant information from the eligible trials and processed the data. This recta-analysis was performed by using Review Manager （5.3） and Stata （14.1） software. Moreover, sensitivity analysis and publication bias of the included studies were evaluated. A total of 12 randomized controlled trials meeting the inclusion criteria were included. Results of the meta-analysis revealed that there was no significant difference between ivabradine group and control groups in cardiovascular mortality （RR = 0.97, 95% CI： 0.89-1.06, P = 0.49）. While the administration of ivabradine was associated with a significant increase in the incidence of bradycardia （RR = 3.90, 95% CI： 2.47-6.17, P〈0.00001） and phosphenes （RR = 4.95, 95% CI： 3.24-7.55, P〈0.00001） as well as atrial fibrillation （RR = 1.24, 95% CI： 1.07-1.43, P = 0.003）. High quality of the included studies was confirmed by quality assessment. No publication bias was observed, and sensitivity analysis confirmed that the obtained results were stable. In conclusion, the meta-analysis proved that the use of ivabradine was associated with a significant increase in the risk of bradycardia, phosphenes and atrial fibrillation. Therefore, clinicians need to take these risks into account when using ivabradine in treatment.

Postmarketing studies on safety of Dengfeng~ shenmai injection

OBJECTIVE: To systematically research the postmarketing safety of Dengfeng shenmai injection, identify potential risk factors, and ensure its clinical safety. METHODS: We investigated a comprehensive series of studies on the production process, quality standards, pharmacology, postmarketing clinical studies, and safety evaluation of Shenmai injection, including literature analysis of adverse drug reaction(ADR) case analysis and systematic review. Data from the hospital information system(HIS) and spontaneous reporting system(SRS) were also analyzed. RESULTS: The approximate dosage leading to death in dogs is 45.0-67.5 g raw drug/kg and the toxic reactions are restlessness, skin irritation, salivation, and vomiting. The results of chronic toxicity tests in mice and dogs, and the other tests such as 6-month toxicity, drug safety, genetic toxicity, and reproductive toxicity of rats and dogs, were positive or qualified. Patient ADR history and ADR family history were closely associated with itching based on the data analysis from SRS. There was no damage to renal function from Shenmai injection use at a dosage and a treatment course outside the recommended dosage and treatment course as specified based on data analysis from HIS. The most common ADR from Shenmai injection are difficulty breathing, facial flushing, nausea, vomiting, chest tightness, skin itching, rash, and back pain. CONCLUSION: This study includes complete information on Shenmai injection ADR incidence rate. We found that Shenmai injection is safe and this study can provide clinical, research, and production institutions with an objective, reliable, and scientific basis for use of Shenmai injection.

Efficacy and safety of Traditional Chinese Medicine for the treatment of acquired immunodeficiency syndrome:a systematic review

OBJECTIVE:To systematically review the efficacy and safety ofTraditional Chinese Medicine(TCM)interventions,compared with control interventions(placebo or conventional Western medical therapy),in the treatment of acquired immunodeficiency syndrome(AIDS).METHODS:Electronic databases including PubMed,the Cochrane Library,China National Knowledge Infrastructure(CNKI),and Wanfang Data were searched to identify relevant randomized controlled trials(RCTs)published as of May 2012.Studies were selected according to the specified inclusion and exclusion criteria and then subjected to methodological quality assessment,data extraction,and meta-analysis according to the Cochrane Handbook for Systematic Reviews of Interventions.RESULTS:Twelve RCTs involving 881 patients with AIDS were included.Methodological quality assessment showed that two were high-quality,two were moderate-quality,and eight were low-quality.Meta-analysis showed that TCM interventions were associated with significantly reduced plasma viral load compared with placebo[odds ratio OR=2.46,95%confidence interval CI(1.02,5.94);P=0.04].However,the reductions in plasma viral load significantly favored conventional Western medical therapy alone over integrated traditional Chinese and Western medical therapy[OR=0.16,95%CI(0.05,0.55);P=0.004].Patients receiving TCM interventions had significantly higher CD4+T lymphocyte counts compared with those on placebo[OR=2.54,95%CI(1.40,4.60);P=0.002].In addition,TCM interventions were significantly more likely to have improved clinical symptoms[OR=2.82,95%CI(1.85,4.31);P<0.00001].TCM interventions conferred a similar risk of adverse events(AEs)compared with control interventions[OR=1.87,95%CI(0.58,6.01);P=0.29].CONCLUSION:Current evidence suggests that TCM interventions are significantly more effective than placebo in reducing plasma viral load and increasing CD4+T lymphocyte count in patients with AIDS.When compared with conventional Western medical therapy,TCM interventions were significantly less effective in reducing plasma viral load,although they were associated with a higher percentage of patients with improved symptoms.Patients receiving TCM interventions did not seem to be at an increased risk of AEs.
