骨盆骨折合并出血性休克的救治

目的探讨骨盆骨折合并出血性休克的救治方法。方法回顾性分析2001年1月-2006年2月收治的85例骨盆骨折合并出血性休克患者的临床资料,根据AIS-ISS创伤评级标准评定伤情。结果本组患者ISS评分均大于16分,平均(33．3±15．5)分,成活60例,死亡25例,抢救成功率70．6％。结论骨盆骨折合并出血性休克的死亡率较高,死亡患者大部分发生在急诊抢救过程中,早期应用合理的抢救措施是降低死亡率的关键。     

Developmental changes of glutamate acid decarboxylase 67 in mouse brain after hypoxia ischemia

Objective To study the developmental changes of glutamic acid decarboxylase-67 (GAD-67, a GABA synthetic enzyme) in normal and hypoxic ischemic (HI) brain. Methods C57/BL6 mice on postnatal day (P) 5, 9, 21 and 60, corresponding developmentally to premature, term, juvenile and adult human brain were investigated by using both Western blot and immunohistochemistry methods either in normal condition or after hypoxic ischemic insult. Results The immunoreactivity of GAD67 was up regulated with brain development and significant difference was seen between mature (P21, P60) and immature (P5, P9) brain. GAD67 immunoreactivity decreased in the ipsilateral hemisphere in all the ages after hypoxia ischemia (HI) insult, but, significant decrease was only seen in the immature brain. Double labeling of GAD67 and cell death marker, TUNEL, in the cortex at 8h post-HI in the P9 mice showed that (15.6±7.0)% TUNEL positive cells were GAD67 positive which was higher than that of P60 mice. Conclusion These data suggest that GABAergic neurons in immature brain were more vulnerable to HI insult than that of mature brain.

儿童群体性皮肤拟除虫菊酯类农药中毒93例

目的报告1次群体性皮肤拟除虫菊酯类农药中毒的情况。方法回顾性总结拟除虫菊酯类农药中毒患儿93例的一般资料、临床表现和治疗措施。结果中毒患儿93例经过心理、物理和药物治疗,1~3 d均治愈,7~14 d随访均正常。结论皮肤接触拟除虫菊酯类农药中毒后,只要及时清洗皮肤,适当应用滴眼液,或经静滴维生素C和地塞米松针剂,一次性使用可消除症状;心理治疗对于群体发病至关重要。     

人巨细胞病毒感染致老年BALB/C小鼠肾脏损伤的实验研究

在机体免疫功能低下或器官移植后出现的潜伏的人巨细胞病毒（HCMV）再激活感染。患者可出现多种组织脏器的损伤，甚至出现严重的肾功能损害，但其病理改变及机制尚不清楚。本研究是在已建立的HCMV先天性潜伏感染老年Balb/C小鼠模型基础上，用环磷酰胺激活小鼠肾组织内潜伏的HCMV，造成急性感染的状态，以观察肾组织的病理变化。     

Further studies on interactions between periaqueductal gray, nucleus accumbens and habenula in antinociception.

Previous findings from this laboratory with the intracerebral microinjection technique suggested that the periaqueductal gray (PAG), nucleus accumbens, and habenula might constitute a unidirectional loop to play their roles in pain modulation. In the present study we demonstrate that intra-habenular injection of naloxone antagonizes the analgesia elicited by morphine injected into the periaqueductal gray (PAG) and that intra-accumbens injection of naloxone is capable of attenuating the analgesic effects of morphine injected into the habenula. These results indicate that the relationships between these nuclei may be more complex than the putative unidirectional loop.

Research on the relation between intrauterine infection and intrauterine growth retardation]

To investigate the relationship between intrauterine infection and IUGR, the following studies have been carried out: (1) measurement of specific antibodies of Toxoplasma (Toxo) and Cytomegalovirus (CMV) in the umbilical serum samples from 30 cases of IUGR with 26 normal newborn infants as controls; (2) follow-up exam on 14 positive cases in 17-25 months. The results showed that in 30 IUGR cases 14 were found to have Toxo and CMV infection, with an incidence significantly higher than that in the control group. One third of the infected patients were found to have retarded growth afterbirth and 63.63% of them appeared to have an increase in BAEP. This suggested that regular follow-up is indicated in these cases.     

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.
