Stem cell therapy for ischemic heart disease / 中国组织工程研究

BACKGROUND:Stem cel transplantation is a promising strategy for treatment of ischemic heart diseases, which has obtained great achievements in recent years. OBJECTIVE: To analyze the clinical trends of stem cel therapy for ischemic heart diseases reported from 2001 to 2015 in Medline, CNKI, Wanfang, ClinicalTrials.gov and Chinese Clinical Trial Register. METHODS:The relevant articles addressing stem cel therapy for ischemic heart diseases were retrieved using the keywords of “stem cel transplantation” and “ischemic heart disease” in Chinese and English in Medline, CNKI, Wanfang, ClinicalTrials.gov and Chinese Clinical Trial Register folowed by statistical analysis. The retrieval time was from 2001 to 2015, including 2001-2005, 2006-2010 and 2011-2015. RESULTS AND CONCLUSION: In Medline database, there were 219 clinical studies about stem cel therapy for ischemic heart disease published from 2001 to 2015, and the number of retrieved articles was most from 2006 to 2010, and decreased from 2011 to 2015. In CNKI and Wanfang databases, the number of relevant articles which had a similar trend with that in the Medline database decreased remarkably after 2011. In ClinicalTrials.gov, there were 63 clinical trials about stem cel therapy for ischemic heart disease, most of which were registered from 2006 to 2015 and came from Europe and North America. In Chinese Clinical Trial Register, there was no clinical trial about stem cel therapy for ischemic heart disease, which may result from the strict management in China.

Relationship between occupational stress and depression in migrant workers / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To investigate the relationship between occupational stress and depression in migrant workers.</p><p><b>METHODS</b>Migrant workers in the textile industry were selected as subjects, and the self-made Occupational Stress Questionnaire and Self-rating Depression Scale were used to investigate the sex, age, seniority, educational level, and marital status of these subjects. Data analysis was performed by independent-samples t test, analysis of variance, Spearman rank correlation analysis, and stepwise multiple regression analysis.</p><p><b>RESULTS</b>Sex, seniority, and educational level were not influential factors for depression scores. The lower age group had a higher moderate depression score than the higher age group; the unmarried group had a higher moderate depression score than the married group. Severe depression was negatively correlated with decision-making power, psychological job demands, social support, and external pay-return, but positively correlated with skills and internal input; moderate depression was positively correlated with psychological job demands and external pay, but negatively correlated with other factors; mild depression was negatively correlated with all factors. The stepwise regression analysis showed that the influential factors for depression included, from major to minor, supervisor support, skills, internal input, and colleague support, according to the standardized regression coefficients; internal input was the contribution factor, and the remaining ones were negative factors.</p><p><b>CONCLUSION</b>Among migrant workers, certain mental health problems exist, and occupational stress is associated with depression.</p>

Effect of cilostazol and aspirin on function of platelet assembly rate and change of protein kinase B activity in elderly patients with acute coronary syndrome / 中国医师进修杂志

Objective To examine the effect function of platelet(Pt)assemble rate(PLTAR) and the change of protein kinase B(PKB) active by cilostazol (CS)and aspirin (AS)on elderly patients with acute coronary sydrome(ACS). Methods Forty-eight elderly patients with ACS were divided randomly into two groups:CS group (100 mg,n=26),AS group (300 mg,n=22).Twenty-six healthy elderly were into the group of normal control(NC group) . The CS group and AS group were treated by routine anticoagulation and antiplatelet.PLTAR and PKB activity were measured at 10 minutes before treatment and at 7 days after treatment 3.5,6.0,24.0 hours. Results The maximum PLTAR in elderly CS group and AS group was elevated significantly compared with NC group(P
