Objective: To study the distribution and development rules of the TCM syndromes in psoriasis vulgaris. Methods: Based on the clinical epidemiologic mass survey, the study was carried out by means of a status survey, multi-center and large-sample research. The data base was set up by EPIINFO6.0. The SPSS was used to do the statistical analyses in 2651 cases of psoriasis vulgaris to study the correlations among the distribution and development of the TCM syndromes, the stages of the disease, nationality, psoriasis history, family history, smoking history, alcohol drinking history, and severity of the disease. Results: The TCM syndromes in psoriasis vulgaris mainly include the blood-heat syndrome (53.8%), blood-dryness syndrome (27.4%), and blood-stasis syndrome (18.1%). Other syndromes were rarely seen, covering 0.6%. The concurrent syndromes mainly involve dampness, heat, blood stasis and toxin. The distribution differences of the main syndromes at different stages of the disease had statistical significance (P0.05), but it was closely related with the psoriasis history, smoking history, alcohol drinking history, and severity of the disease (P<0.01). Conclusion: At the initial stage, psoriasis vulgaris usually manifests itself as the blood-heat syndrome, and later it may be improved or turn into the blood-dryness or blood-stasis syndrome. Smoking, alcohol consumption, and severity of the disease may play a role in the syndrome's transformation.

Optimal timing of staged percutaneous coronary intervention in ST-segment elevation myocardial infarction patients with multivessel disease

Journal of Geriatric Cardiology 2018年第5期15卷 356-362页

作者： Xue-Dong zhao Guan-Qi zhao Xiao wang Shu-Tian SHI wen ZHENG Rui-Feng GUO Shao-ping NIE beijing Anzhen Hospital Capital Medical University Beijing Institute of Heart Lung and Blood Vessel Diseases Beijing China

Background Studies have shown that staged percutaneous coronary intervention （PCI） for non-culprit lesions is beneficial for prog- nosis of ST-segment elevation myocardial infarction （STEMI） patients with multivessel disease. However, the optimal timing of staged re- vascularization is still controversial. This study aimed to find the optimal timing of staged revascularization. Methods A total of 428 STEMI patients with multivessel disease who underwent primary PCI and staged PCI were included. According to the time interval between primary and staged PCI, patients were divided into three groups （〈 1 week, 1- weeks, and 2-12 weeks after primary PCI）. The primary endpoint was major adverse cardiovascular events （MACE）, a composite of all-cause death, non-fatal re-infarction, repeat revascularization, and stroke. Cox regression model was used to assess the association between staged PCI timing and risk of MACE. Results During the follow-up, 119 participants had MACEs. There was statistical difference in MACE incidence among the three groups （〈 1 week： 23.0%; 1-2 weeks： 33.0%; 2-12 weeks： 40.0%; P = 0.001）. In the multivariable adjustment model, the timing interval of staged PCI ≤ 1 week and l-2 weeks were both significantly associated with a lower risk of MACE [hazard ratio （HR）： 0.40, 95% confidence intervals （CI）： 0.24-4）.65; HR： 0.54, 95% CI： 0.3 lq3.93, respectively], mainly attributed to a lower risk of repeat revascularization （HR： 0.41, 95% CI： 0.24-0.70; HR： 0.36, 95% CI： 0.18-0.7）, compared with a strategy of 2-12 weeks later of primary PCI. Conclusions The optimal timing of staged PCI for non-culprit vessels should be within two weeks after primary PCI for STEMI patients.
