Therapeutic effects of Tongdu Qishen acupuncture combined with traditional Chinese medicine decoction on post-stroke depression in 31 patients / 中国基层医药

Objective:To investigate the clinical effects of Tongdu Qishen acupuncture combined with traditional Chinese medicine decoction on post-stroke depression in patients. Methods:Sixty-two patients with post-stroke depression who received treatment in Zhongda Hospital of Southeast University from October 2020 to April 2022 were included in this study. They were randomly treated either with traditional Chinese medicine decoction (control group, n = 31) or Tongdu Qishen acupuncture combined with traditional Chinese medicine decoction (combined group, n = 31) based on routine medication. All patients were treated for 4 weeks. Depressive state, neurological function, and activities of daily living were compared between the two groups. Results:Before treatment, there were no significant differences in the Hamilton Depression Scale (HAMD) score, National Institutes of Health Stroke Scale (NIHSS) score, and Barthel index between the two groups (all P > 0.05). After 4 weeks of treatment, the HAMD and NIHSS scores in the control group were (13.88 ± 3.92) points and (8.56 ± 1.82) points, respectively, and they were (8.72 ± 2.48) points and (6.67 ± 1.14) points in the combined group. There were significant differences in HAMD and NIHSS scores between the two groups ( t = 2.14, 2.43, both P < 0.05). The Barthel index in the combined group was (69.53 ± 13.29) points, which was significantly higher than (62.34 ± 15.67) points in the control group ( t = 2.23, P < 0.05). Conclusion:Tongdu Qishen acupuncture combined with traditional Chinese medicine decoction can reduce depressive symptoms and improve neurological function and activities of daily living in patients with post-stroke depression. The combined therapy has obvious efficacy in the treatment of post-stroke depression.

Studies on prevalence and control of several common chronic diseases among Beijing adults in 2005 / 中华流行病学杂志

<p><b>OBJECTIVE</b>To understand the prevalence and control of several common chronic disease in Beijing adults.</p><p><b>METHODS</b>16,658 adult residents were randomly selected with stratified multi-stage cluster sampling method. Each participant was invited to receive a set of standardized questionnaire, physical examinations and laboratory tests.</p><p><b>RESULTS</b>Data showed that the prevalence, awareness, treatment and the rate of control on hypertension among the adults in Beijing were 29.1%, 49.3%, 42.3% and 10.6% respectively. The counterparts of diabetes mellitus were 8.8%, 56.7%, 50.0% and 15.0%. The four corresponding figures for dyslipidemia were 33.2%, 31.1%, 13.0% and 4.3%, respectively. 22.9% of the Beijing adults had metabolic syndrome including 8.1 per thousand suffering from myocardial infarction and 18.4 per thousand from stroke. Except for diabetes, all the chronic diseases had higher prevalence rate in rural area than in urban area, according to the findings under our study. Postmenopausal women were more susceptible to chronic disease than men.</p><p><b>CONCLUSION</b>The prevalence rate of chronic disease in Beijing was still high. The prevalence rate in rural area had exceeded the level in urban area. Adjustment and attention should be made according to the prevalence features and weakness existed in present chronic disease control strategy.</p>

Demethylation of progesterone receptor in leukemia cell line induced by DNMT1 antisense oligonucleotide wrapped in liposome / 第三军医大学学报

Objective To investigate the effects of the transfection of DNMT1 antisense oligonucleotide wrapped in liposome on the promotor methylation and expression of progesterone receptor in leukemia cell lines so as to find a new pathway of methylation for gene therapy. Methods Artificially synthesized DNMT1 antisense oligonucleotide MG88 wrapped in liposome was transfected into the leukemia cell line. Changes of DNMT1 & PRB mRNA were detected by RT PCR, and the changes of the methylation status of PRA & PRB were analyzed by MSP. Results After transfection of leukemia cell line with MG88, DNMT1 mRNA decreased significantly. PRA & PRB promotors were demethylated, and the expressions of PRB mRNA increased significantly. Conclusion MG88 can induce the demethylation of PR promoters in leukemia cell line, resulting in the increase of PRB mRNA expression. So MG88 can be used in the experimental study of DNA methylation for gene therapy.

Changes of Selenium Metabolism,Glutathione Peroxidase Activity and Lipid Peroxides Content in Severely Scalding- injured Rats / 第三军医大学学报

The changes of selenium metabolsim, glutathione peroxidase acivity and lipid peroxides content in the tissues of rats suffering from 30% TBSA full thickness scalding were observed in the first 7 days after injury. It was found that selenium content in the rat tissues decreased remarkably after injury,which in turn resulted in serious reduction of glutathione peroxidase activity and significant increase of lipid peroxides in the serum, erythrocytes and liver. However the muscular tissue showed no significant changes.These facts imply that after burn injury, the body is in a state of selenium deficiency, the loss of selenium might be responsible for the reduction of anti-peroxidation ability of glutathione peroxidase, and consequently there is an increase of lipid peroxides in the tissues. Only the muscular tissue is insensitive to lipid peroxiation. It is believed that the reduction of anti-peroxidation ability of glutathione peroxidase after burn injury might be one of the main causes to intensify the injury resulting from free radicals.
