王不留行对家兔离体主动脉环张力的影响及其机制

目的:研究王不留行水煎液(DSC)对兔离体主动脉环张力的影响及其机制.方法:采用家兔离体主动脉环张力记录法.结果:DSC可浓度依赖性地引起动脉血管静息张力的增加.用10-7mol/L酚妥拉明、10-5mol/L异搏定、10-6mol/L苯海拉明或无钙K-H液温育后均可明显减弱DSC的收缩作用;而去除内皮细胞后,10-7mol/L阿托品则无明显影响.结论:DSC可引起主动脉环收缩,其机制可能与平滑肌细胞上的肾上腺素能α受体、异搏定敏感的Ca2 通道、细胞外Ca2 以及组胺H1受体有关,而与血管内皮细胞和胆碱能M受体无关.     

全反式维甲酸联合亚砷酸对NPM1阳性老年非早幼粒细胞急性髓细胞白血病患者的疗效分析

【摘要】 目的 研究全反式维甲酸（ATRA)联合亚砷酸(ATO)对NPM1阳性老年非早幼粒细胞急性髓细胞白血病（ non APL AML）患者的疗效。方法 选取2012年2月～2017年2月我院收治的NPM1老年非早幼粒细胞AML患者76例为研究对象。将其按照随机数字表法均分成观察组和对照组,每组各38例。对照组予以小剂量阿糖胞苷（LDAC）化疗,观察组则在LDAC基础上联合ATO及ATRA化疗。分别比较两组早期死亡率、完全缓解率、复发率情况,不良反应发生情况以及1年生存率情况。结果 观察组完全缓解率高于对照组,而复发率低于对照组,差异有统计学意义（均P＜005）。两组肝功能损害、胃肠道反应以及头痛发生率比较差异无统计学意义（均P＞005）。观察组1年生存率高于对照组,差异有统计学意义（P＜005）。结论 应用ATRA联合ATO及LDAC使老年NPM1阳性 non APL AML患者完全缓解率,降低复发率,延长1年生存率,具有较高的安全性,值得临床进一步研究。     

Phacoemulsification in eyes with corneal opacities after deep anterior lamellar keratoplasty

To evaluate the maneuverability and efficacy of phacoemulsification and intraocular lens (IOL) implantation in eyes with corneal opacities after deep anterior lamellar keratoplasty (DALK), twelve eyes of 12 patients with mild to moderate corneal opacities after DALK and coexisting cataracts were analyzed retrospectively. Phacoemulsification and IOL implantation assisted with anterior capsule staining, as well as non-invasive optical fiber illumination, were performed on all eyes. No intraoperative or postoperative complications were noted. Mean corrected distance visual acuity (logMAR) improved from 1.24±0.17 to 0.73±0.22. Post-phaco intraocular pressure was maintained between 13 to 20 mm Hg in all cases throughout the follow-up period. Mean endothelial cell density decreased from 2258.42±205.94 to 1906.25±174.23 cells/mm2. Phacoemulsification and IOL implantation are safe and valid in eyes with mild to moderate corneal opacities after DALK and coexisting cataracts when assisted with anterior capsule staining and non-invasive optical fiber illumination.

脑梗死患者血清高敏C反应蛋白的变化及临床意义

目的探讨脑梗死患者血清高敏C反应蛋白(hsCRP)含量的变化及其临床意义。方法随机选择57例脑梗死患者,检测其高敏C反应蛋白的血清水平。观察脑梗死不同病情含量变化,并分析与患者临床神经功能缺损程度评分的相关性。结果脑梗死患者的血清hsCRP水平明显高于正常对照组(P<0.01)。脑梗死不同临床分型组间血清hsCRP水平比较,重型组明显高于中型、轻型组,差异均有统计学意义(P<0.01)。脑梗死患者血清hsCRP含量与临床神经功能缺损程度评分呈正相关(r=0.255,P<0.05)。结论血清hsCRP水平增高与脑组织受损程度有密切关系。hsCRP升高可能是脑梗死发病的一个危险因素。hsCRP升高对治疗及估计预后有指导意义。     

The altering in sensory sensitivity: a current issue of female breast surgery

Breast surgery is an important treatment for women with malignant breast diseases. In addition to breast appearance, the integrity of breast function is increasing in patients with breast diseases. As the basis of breast physiological function, breast skin sensitivity is important to the quality of life of patients after surgery. Breast skin sensitivity gives the patient a “real” breast feeling. The sensory recovery after breast surgery has also become one of the important goals of breast surgery. In this review, we aim to discuss the research progress on recovery of breast skin sensitivity after different treatment modalities for breast disease.     

淫羊藿甙抗癌作用机制的实验研究

中药单体淫羊藿百一种新型的生物反应调节剂和诱导分化剂。为进一步探讨淫羊藿 作用机制,我们将淫羊藿和于人高转移肺癌细胞ＰＧ,采用ＭＴＴ、放免、流式细胞术、粘附实验,运动侵袭实验等多种手段进行了检测。结果表明,淫羊藿夼直接抑癌作用较强,但却能影响ＰＧ细胞周期的时相分布,使Ｓ期减小,并能升高细胞内ｃ－ＡＭＰ水平,降低ｃＧＭＰ水平,提示ｃＡＭＰ／ｃＧＭＰ比值,同时降低ＰＧ细胞对胞外基质的粘附性及侵袭、运动
