THE EFFECT OF ACUPUNCTURE ON PREVENTION AND TREATMENT OF ISCHEMIC ARRHYTHMIA AND THE RELATION BETWEEN EFFECT OF ACUPUNCTURE AND CHOLINERGIC MUSCARINE-LIKE RECEPTORS

For investigating the effect of acupuncture on ischemic arrhythmia and its mech-anism, adult albino rats with ligated anterior descending branch of coronary artery as experimentalmodel were treated with or without acupuncture, and others with imitative operation but without bothcoronary artery ligation and acupuncture treatment were used as control. It was found in acupuncturegroup that the fibrillation-liability of ischemic myocardium was efficiently decreased, the affinity ofAch-M receptors on membranes of ischemic myocardium was markedly increased, and the tolerance ofischemic myocardium to atropine was elevated in the experiment of atropine inducing fibrillation.These results indicate that acupuncture may play a therapeutic role on ischemic arrhythmia throughactivating the activity of muscarine-like receptors of cholinergic nervous system.     

小剂量异丙酚加喉上神经阻滞用于纤支镜检查

目的：观察异丙酚加喉上神经阻滞用于纤支镜检查期间，患对操作刺激反应、耐受程度以及对心血管反应和遗忘程度。方法：选40例拟诊肺癌患行ASAⅡ～Ⅲ纤支镜检查，喉上神经阻滞成功后推注0．5～1mg／kg异丙酚，患意识消失后，进行纤支镜操作。结果：所有病人都能耐受检查。术中收缩压、舒张压、心率、血氧饱和度等无明显影响，无恶心、呕吐等并发症，大大减轻了检查对病人带来的痛苦。结论：异丙酚加喉上神经阻滞用于纤支镜检查，对呼吸、循环影响小，能减轻病人痛苦，术后具有遗忘作用，值得推广。     

慢性肾衰竭患者并发神经精神症状临床分析

目的 分析慢性肾衰竭并发神经精神症状的原因.方法 回顾性分析我院34例出现神经精神症状的慢性肾衰竭患者的资料.结果 慢性肾衰竭并发神经精神症状的原因主要是尿毒症毒素蓄积及代谢紊乱;此外与透析不充分、失衡综合征、脑血管病变、精神压力及药物等因素有关.结论 慢性肾衰竭患者出现神经精神症状与多因素有关,应积极治疗原发病,早期充分透析.     

高血压病心尖搏动图的改变

50例高血压病人ACG和 FDACG 检测的结果显示:高血压病不论舒张压高低或有无心脏增大,均有舒张功能改变,表现为A/EO 比值增高,A_2-dA/dt-min 和A_2O延长。此三项指标的异常出现率分别为40％、30％及14％,三项联合检测其中任何一项异常的出现率为54％。收缩功能无明显改变。治疗显效后,A/EO降低,A_2-dA/dt-min 缩短,说明心功能明显改善。     

有助于残根修复的牙冠延长术

牙折裂达龈下、或龋坏导致的残根达龈下时,修复常难以进行,残根往往被拔除。然而,若对残根进行完善的根管治疗,再采用一定的方法使牙断缘暴露出来,则残根可以被保留并可进行修复。在暴露残根断缘的方法中,有学者采用牵引方法,将儿童和青少年外伤牙的残根牙缘牵至龈上,但这需要较长的时间和过程,有时还会有回缩的现象[1] 。大多数医生以往多采用牙龈切除术来暴露牙断缘,但随之而来的问题是,在尚未来得及修复时牙龈又恢复至原来水平。因而有的医生在术后第2天就进行修复,有的则用电刀切除牙龈之后立即修复,然而,在修复之后,牙龈往往会有长时间…     

糖尿病人红细胞免疫粘附功能的变化

测定６２例糖尿病人的红细胞Ｃ３ｂ受体花环（ＲＣ３ｂ）和免疫复合物花环（ＲＩＣ）；同时测定血糖、胰岛素、糖化血红蛋白和血清循环免疫复合物（ＳＣＩＣ），并和３０例对照组比较。结果显示糖尿病组ＲＣ３ｂ显著低于对照组。高ＨｂＡｌ组ＲＣ３ｂ明显低于正常ＨｂＡ１组（Ｐ＜０．０１）。ＲＩＣ在高ＨｂＡ１组显著高于其他组（Ｐ＜０．０１）。糖尿病组ＳＣＩＣ显著高于对照组；高ＨｂＡ１组显著高于正常ＨｂＡ１组。ＳＣＩＣ和ＲＩＣ的结果呈现相关（ｒ＝０．７１３，ｒ＜０．０１）。提示糖尿病人ＲＣ３ｂ下降与血清ＳＥＩＣ水平升高有关，与血糖控制有密切关系。     

The Effect of Acupuncture on Bone Mineral Density in Postmenopausal Women

According to the TCM theory that the kidney is in charge of the bone, the authors carried out a study on the effect of acupuncture on bone mineral density in 40 postmenopausal women with osteoporosis treated by the method of reinforcing the kidney to strengthen the bone, with satisfactory therapeutic results reported as follows.     

Agilent 2100 Bioanalyzer在基因差异表达研究中的应用

目的：观察Agilent2100 Bioanalyzer芯片分析系统（以下简称Bioanalyzer）在基因差异表达研究中的应用。方法：应用限制性显示技术分别从正常和热休克处理后的酿酒酵母细胞中分离出cDNA片段，然后再用Bioanalyzer和传统的琼脂糖凝胶电泳技术对RD-PCR产物进行检测分析。结果：Bioanalyzer能更快速、敏感地分离和显示差异表达的基因片段，并且通过对差异片段进行定量比较，发现了数个表达有明显差异的基因片段。结论：Bioanalyzer在基因差异表达研究中具有重要的应用价值。

Experimental studies of electroacupuncture on ventricular fibrillation threshold in rats with acute ischemic myocardium

Summary By ligating the proximate left anterior descend (LAD) of coronary artery and inducing the ventricular fibrillation with electrical stimulation, the preventive effects of electroacupuncture (EA) on ventricular fibrillation were observed. The results showed that the ventricular fibrillation threshold (VFT) of rats with acute ischemic myocardium was raised after acupuncturing some acupoints, which could prevent the occurrence of ventricular fibrillation. Furthermore, the combination of EA and propranolol could enhance the VFT effectively, and they showed a good synergistic effect.
