基于中医养生理论的辨体质施护对支气管哮喘缓解期患者的影响

目的探讨依据中医体质和养生理论制订的中医辨体质施护措施对支气管哮喘缓解期患者干预效果的影响。方法选取2016年3月—2017年6月在笔者所在医院肺病科确诊为支气管哮喘的住院患者188例,随机分为试验组和对照组,各94例。对照组采用常规护理方法,试验组在常规护理的基础上采用根据中医体质和养生理论制订的中医辨体质施护措施,并比较2组患者症状控制、生存质量及肺功能。结果试验组与对照组入院时哮喘控制测试量表(asthma control test,ACT)评分、哮喘生存质量评估表(asthma quality of life questionnaire,AQLQ)评分及肺功能FEV1%无明显差异。进行护理干预后,试验组ACT评分、AQLQ评分及FEV1%明显升高(P <0. 05),与对照组相比,差异具有统计学意义(P <0. 05)。结论根据中医体质和养生理论进行辨体质施护可以有效改善支气管哮喘缓解期患者的临床症状,提高其生存质量和肺功能。

Properties,Morphology and Structure of BPDA/PPD/TFMB Polyimide Fibers

The mechanical properties of fibers were notably improved by incorporating 2,2＇-bis（trifluoromethyl）benzidine（TFMB） into 3,3＇,4,4＇-biphenyltetracarboxylic dianhydride（s-BPDA） and p-phenylenediamine（PPD） backbone.The best strength and modulus of BPDA/PPD/TFMB polyimide（PI） fiber（diamine molar ratio of PPD/TFMB= 90/10） were 1.60 and 90 GPa,respectively,which was over two times that of BPDA/PPD PI fiber.SEM image showed that the cross-section of fibers at each stage was round and voids free.Besides,the ＂skin-core＂ and microfibrillar structure were not observed.The thermal properties of PI fibers were also investigated.The results showed that the fibers owned excellent thermal stability,moreover,the structural homogeneity of fibers were significantly improved by heat-drawn stage.The T g values were found to be around 300 °C by dynamic mechanical analysis（DMA）.Wide angle X-ray diffraction（WAXD） and small angle X-ray scattering（SAXS） experiments indicated that the order degree of longitudinal and lateral stacks,the molecular orientation and the structural homogeneity of fibers were improved in the preparation process of fibers.

Impact of weight gain following smoking cessation on one-year outcome after drug-eluting stent implantation

Background Weight gain following smoking cessation increases cardiovascular risk, but its effects on prognosis after percutaneous coronary intervention （PCI） remain unclear. This study aimed to investigate the relationship between weight gain post smoking cessation and one-year clinical outcome in patients who underwent PCI with drug-eluting stent （DES）. Methods A total of 895 consecutive male smoking patients were divided into quitters （n=437） and continuers （n=458） according to their smoking status after PCI. Weight gain, major adverse cardiac events （MACE, including cardiac deaths, myocardial infarction and revascularization）, and recurrent angina were recorded during follow-up for one year. Results Average weight gain in quitters was more than that in continuers （1.5 kg vs. -0.03 kg, P〈0.001）. Weight was unchanged or increased by more than 1.5 kg in 78.17% of continuers, while 50.57% of quitters had a weight gain of less than 1.5 kg. Compared with continuers, MACE in quitters was significantly reduced after PCI （6.12% vs. 4.81%, P=0.049）, especially recurrent angina （13.97% in continuers vs. 9.84% in quitters, P=0.027）. After adjusting for weight gain and other factors, smoking cessation was independently associated with a lower risk of MACE and recurrent angina （0R=0.73, P=0.035）. However, weight gain 〉1.5 kg （OR=1.55, P=0.026） could curtail the benefits from smoking cessation. Conclusions Weight gain may reduce the benefits of smoking cessation after PCI with DES implantation. Thus, although smoking cessation is recommended after PCI, weight control should also be highly encouraged for these patients.
