电针家兔耳穴对血压和膈神经放电作用实验研究

对比观察在自然呼吸、窒息兴奋期和抑制期电针28只麻醉家兔“降压点”穴对动脉血压和积分膈神经放电的影响,经124次实验发现:于上述三种状态下电针耳穴血压下降分别为7.48±0.67kpa(P 0.01)、4.83±0.63kpa和4.25±0.7kpa(p<0.05);积分膈神经放电频率增快为2.87±0.26次/10秒,3.54±0.31次/10秒和3.24±0.41次/10秒(p<0.01)。结果表明电针该穴有显著降压阳增快呼吸频率的作用,其中兴奋期比抑制期降压更为明显。为临床进一步研究耳针对高血压急症和呼吸衰竭的抢救提供了实验资料。     

电针及生物活性物质对大鼠多形核细胞杀菌功能的影响

用改良的四氮唑硝基蓝（ＮＢＴ）还原法观察了电针以及生物活性物质（ＢＡＳ）包括５－羟色胺（５－ＨＴ）、血管活性肠肽（ＶＩＰ）、生长抑素（ＳＯＭ）和Ｐ物质（ＳＰ）对大鼠多形核白细胞（ＰＭＮ）杀菌功能的影响。结果表明：电针及ＢＡＳ均能增强大鼠ＰＭＮ的杀菌功能（Ｐ＜０．０１）；ＢＡＳ对大鼠ＰＭＮ的杀菌功能具有双向调节效应。纳洛酮可阻抑电针对ＰＭＮ杀菌功能的提高（Ｐ＞０．０５）；可被ＢＡＳ所翻转。电针的镇痛效应和ＮＢＴ阳性细胞提高效应之间存在着明显的正相关（Ｐ＜０．０１）。     

电针对大鼠海马兴奋性突触后电位长时程增强的作用

目的 观察电针对麻醉状态下正常和东莨菪碱引起的学习记忆减退模型大鼠海马突触EPSP长时程增强(LTP)的作用。方法 引导大鼠海马齿状回颗粒细胞层突触后兴奋性电位群(EPSPs)，强直刺激(HFS)大脑皮层前穿质区引起海马突触LTP反应；用东莨菪碱制备学习记忆障碍模型；观察电针大椎和肾俞穴对正常和模型大鼠海马LTP的影响。结果 电针对HFS诱发的海马突触LTP效应，其作用强于未电针组，部分参数和时段有统计学意义(P＜0．05)，且维持时间长于后者；东莨菪碱i．p可显著抑制HFS诱发的海马突触LTP(P＜0．01)，电针能显著对抗这一抑制作用(P＜0．01；P＜0．05)。结论 电针对HFS引起的海马突触LTP有一定的易化作用，并对东莨菪碱引起的学习记忆障碍有显著的对抗作用。     

突发性耳聋甲皱微循环改变及针刺的影响

目的：观察突发性耳聋患甲皱微循环改变及针刺的影响。方法：采用自身前后对照的方法。对突发性耳聋患针刺前后甲皱微循环进行记录。结果：突聋患甲皱微循环明显异常，针刺后患甲皱微循环加权积分值明显改善（P＜0．05）。结论：针刺可改善突聋甲皱微循环状态，提示针刺治疗突聋的机制可能与患外周血液循环得到改善有关。     

三种脐疝修补术式的应用探讨

目的 总结脐疝修补术的经验.方法 回顾性分析了我院自2003～2008年期间收治的49例成人脐疝患者手术治疗的临床资料,其中14例行传统脐疝修补术,21例行Kugel补片无张力修补术,14例行疝环填充式无张力修补术,并对3种术式进行分析和总结.结果 14例传统脐疝修补术随访1年后除1例复发,其余均获成功.35例行无张力修补术亦获成功,随访无1例复发.无张力修补术术后疼痛均较轻,但Kugel补片无张力修补术手术时间略长于传统修补术.结论 无张力修补术在治疗成人脐疝中具有安全有效、术后并发症较少,可获得较满意的手术效果.     

单脐动脉与胎儿畸形（附9例分析）

我科自１９８９～１９９２年在２３８例胎盘病检中发现单脐动脉９例，发生率３．７８％。单脐动脉胎儿的特点是畸形率高、死亡率高。本组９例中８例胎儿有各类畸形，畸形率达８８．９％。７例胎儿死亡命死亡率７７．８％。本文就单脐动脉的发生率、形成原因及其与胎儿畸形的关系进行讨论，建议加强妊娠早期保健及围产期检查工作。及早发现单脐动脉胎儿，可为诊断先天性畸形或发现一些隐性畸形提供线索，从而指导临床产科处理，有利于优生优育。     

Absence of a relationship between umbilical cord thickness and coiling patterns.

OBJECTIVE: The purpose of this study was to evaluate a relationship between the umbilical cord thickness and cord coiling patterns during the fetal sonographic anatomic survey in the second trimester of pregnancy. METHODS: This was a prospective study of 470 patients with singleton pregnancies who had a fetal anatomic survey with recorded umbilical coiling patterns between 18 and 23 weeks' gestation. The umbilical cord thickness was assessed as an umbilical diameter at the level of the fetal abdominal cord insertion and compared with the antenatal umbilical coiling index (aUCI), calculated as a reciprocal value of the distance between a pair of umbilical cord coils. RESULTS: Three hundred twenty-one patients had adequate sonographic umbilical cord images and maternal demographic, antenatal, and labor data to meet inclusion criteria. The mean aUCI was 0.41 with 10th and 90th percentiles of 0.21 and 0.60, respectively. A total of 10.6% (34/321) and 9.3% (30/321) of patients were categorized as having hypocoiled and hypercoiled umbilical cords, respectively. The mean cord diameter +/- SD was 9.48 +/- 0.97 mm (range 7.0-12.5 mm). There was no statistically significant correlation between aUCI and umbilical cord thickness (P = .1164). CONCLUSIONS: An aUCI, or umbilical coiling pattern, does not correlate with umbilical cord thickness. It appears that a lesser amount of the umbilical supportive tissue, mainly Wharton jelly, is not related to an increased umbilical cord coiling pattern.     

Lähmung des N. hypoglossus nach operativem Eingriff – Behandlung mit Akupunktur

Acupuncture is able to accelerate the process of healing significantly when employed in cases of nerve paresis as shown in the following analysis. The patient's constant condition of speech and swallowing impediment before treatment changed relatively fast after starting acupuncture treatment. It is self evident that we took into account the primary disease (AIDS) and its problems. The simplicity of a complementary treatment with acupuncture according to the possible results should make us consider the use of acupuncture as an important way to treat paresis in the early subacute phase and if possible during clinical stay.
