神经生长因子对脑外伤后人格改变的影响

目的探讨神经生长因子（NGF）对脑外伤后的人格改变的影响及治疗效果。方法选取2006年4月1日至2008年9月1日本院脑外伤住院患者（入院时GCS评分10～12）的39例,按入院顺序完全随机分为对照组（19例）和治疗组（20例）。对照组以维生素B1、B12和高压氧等常规治疗并,并给予生理盐水2ml作空白对照;治疗组在常规治疗基础上,以神经生长因子（NGF）剂量为6000U/日,每日肌注1次。两组均以28天为一个疗程,期间观察其意识状态和肝肾功能变化。一疗程后通过症状自评量表（SCL-90）、艾森克人格问卷（EPQ）等对人格改变因素进行临床研究。结果两组神经功能变化无明显差异;与对照组比较,治疗组心理、人格水平显著改善（P〈0.05）;症状自评量表（SCL-90）大部分因子得分高于对照组（P〈0.05）。结论神经生长因子（NGF）对脑外伤后出现心理和人格变化有一定治疗作用。     

丙泊酚用于精神病患者人工通气镇静治疗的临床效果评价

目的研究丙泊酚对精神病患者人工通气在治疗慢性阻塞性肺疾病（COPD）伴重度高碳酸性呼吸衰竭的镇静效果。方法将44例COPD伴重度高碳酸性呼吸衰竭的精神病患者按入院顺序完全随机分为2组各22例,对照组：咪唑安定静脉注射10—20mg;丙泊酚组：丙泊酚静脉注射泵持续输注0．5～2．0mg/（kg·h）,比较治疗0．5、1h后,2组动脉血气分析中的pH值、氧分压（PaO2）、二氧化碳分压（PaCO2）变化,峰值气道压力（Pmax）、平台压（Ppalt）以及肺功能中第1秒用力呼气量与用力肺活量的比值（FEV1／FVC）和呼气峰流速（PEF）的变化。结果丙泊酚组的镇静效果显著优于对照组;与对照组比较,丙泊酚组在治疗后PaCO2显著降低,pH值在治疗后0．5h回到正常范围内,恢复较迅速（P〈0．05或P〈0．01）;治疗后0．5h的PaO2、PaO2／FiO2也比对照组明显升高。丙泊酚组在治疗后的Pmax、Ppalt较对照组有明显下降,PEF、FEV1／FVC的提高较对照组显著,差异有统计学意义（P〈0．05或P〈0．01）。结论丙泊酚进行镇静在COPD伴重度高碳酸性呼吸衰竭治疗中可降低气道阻力,改善氧合功能,减少精神病患者的人机对抗。

Objective To evaluate the association of 2616c/T polymorphism in iron regulatory protein 2(IRP2)gene with Alzheimer disease(AD)and Vascular dementia(VD).Methods In this study,281 patients with AD,60 with VD,and 285 normal aged were recruited.The 2616C/T polymorphism in IRP2 gene was analyzed by using polymerase chain reaction-restriction fragment length polymorphism.And the cognitive function was assessed with the Mini-Mental State Examination(MMSE).Results (1)No significant difieFences were demonstrated in IRP2 genotype or allele frequencies between AD patients and controls(χ2=2.46,P=0.292;χ2=2.17,P=0.141 respectively).However,when AD patients were stratified by disease severity.the frequency of T allele carriers in the moderate to severe AD patients was 78.0%,significantly higher than that in controls(69.8%;χ2=4.106,P＜0.05).Logistic regression analysis demonstrated that the age-,sex-and ApoE-adiusted OR of modcrate to severe AD patient with T allele was 1.62(95% CI=1.03-2.54).The frequency of T allele carriers or T allele in VD patients was higher than that of controls,but the difference was not statistically significant(P＞0.05).(2)The frequency of tit genotype or T allele in the moderate to severe AD patients was significantly higher than that in mild AD patients(25.8%vs.12.5%,χ2=5.477,P＜0.05;51.9%vs.40.3%,χ2=5.803,P＜0.05 respectively).(3)MMSE scores of the AD patients with TT genotype was significantly lower than ones with CC or CT genotype(P=0.028;P=0.014 respectively).Conclusion The 2616C/T polymorphism in the IRP2 gene is possibly associated with moderate to severe AD.but not associated with VD.And the TT genotype may be a risk factor for cognitive impairment of patients with AD in Chinese Han.

磷酸二酯酶同工酶——哮喘治疗的新靶点

茶碱 ,尽管用于临床治疗支气管哮喘已有半个多世纪的历史 ,目前对其药理作用的机制仍然存有很大争议。它在体外实验中非选择性地抑制磷酸二酯酶 (ＰＤＥ)的所有同工酶 ,故传统认为茶碱是通过抑制ＰＤＥ ,减少ｃＡＭＰ的水解而起作用。然而近几年研究结果显示 ,体外实验的茶碱浓度远远高于其有效的血浆浓度 ,治疗浓度的茶碱对ＰＤＥ的抑制率仅为5 %～ 2 0 % ,而且它在小剂量下也具有抗炎和免疫调节的作用。此外 ,它还能拮抗腺苷引起的支气管痉挛 ,刺激肾上腺髓质和肾上腺以外的嗜铬细胞释放儿茶酚胺 ,干扰呼吸道平滑肌细胞内钙离子移动 ,兴奋…
