金丹肝泰1号对大鼠急性肝损伤防治作用的实验研究

用D-氨基半乳糖（D-GaIN）制备大鼠急性肝损伤模型。方法：检测血清丙氨酸氨基转氨酶（ALT）和血清天门冬氨酸氨基转氨酶（AST）的活性，观察光镜下肝组织的病理学改变，探讨对急性肝损伤的保护作用。结果：口服浸膏可显降低急性肝损伤大鼠血清ALT和AST水平，减轻肝细胞的变性坏死，其作用强度与肝炎宁相当，但弱于联苯双酯。     

LightCycler实时监测PCR定量分析血清HBV DNA

目的 检验LightCycler实时监测PCR（real-time detection PCR,RTD-PCR)对血清中HBV DNA定量检测的灵敏性和可重复性，探讨HBV血清标志物与HBV DNA定量的关系。方法 HBV定量按深圳匹基公司乙肝PCR荧光检测试剂盒使用说明，对乙肝标志物已明确的773例血清中HBV DNA定量结果进行统计分析。结果 实时监测PCR对血清中HBV DNA定量检测的灵敏性高，可检测低至1000拷贝／ml血清；可重复性好，批间误差＜20％；各种标志物类型的血清HBV DNA含量分布情况表明，HBV血清标志物中HBeAg与HBV DNA含量有明显的关系，一般HBeAg阳性血清HBV DNA含量较高，但也有相当一部分例外。结论 LightCycler实时监测PCR对血清中HBV DNA定量检测灵敏性高可重复性好；仅根据HBV血清标志物往往不能确定乙肝患者HBV DNA复制水平的高低，HBV DNA定量检测具有十分重要的临床意义。     

猪血中脱色球蛋白的制备及其功能性研究

比较了几种拆分剂分离猪血红细胞中血红蛋白的效果，其中羧甲基淀粉（ＣＭＳ）得到最佳效果。脱色球蛋白的功能性实验证实其有良好的起泡和乳化性能，氨基酸分析显示其赖氨酸和组氨酸的含量较高，适合作为婴儿的营养强化剂。     

CHILDREN'S CONSENT TO PSYCHIATRIC TREATMENT: ALL OR NOTHING?

An adolescent with a history of attempted suicide who refused to involve his father in the treatment plan is presented. Issues surrounding consent to psychiatric treatment in childhood are discussed and the assessment process outlined. Contributions by primary healthcare professionals are emphasised.     

羟乙基淀粉容量治疗对高龄病人手术的血流动力学影响

目的观察羟乙基淀粉130/0.4氯化纳注射液(6%HES,万汶),应用于老年患者容量治疗时对血流动力学的影响。方法选择30例ASAⅠ～Ⅱ级择期手术的老年患者,给予万汶进行容量治疗,观察术中血流动力学变化。结果所有患者术中血流动力学保持稳定。结论万汶应用于老年患者进行容量治疗时血流动力学保持稳定。     

黄芪、雷公藤多甙对大鼠肾小球系膜细胞分泌IL-6的影响

目的:观察黄芪和雷公藤多甙对大鼠肾小球系膜细胞分泌IL-6水平的影响.方法:应用细胞培养技术进行肾小球系膜细胞培养,采用血清药理学方法,制备黄芪药物血清,雷公藤多甙药物血清,并分为低、中、高3个剂量梯度,观察药物血清对正常状态下肾小球系膜细胞分泌IL-6的影响,采用细胞ELISA法测定IL-6含量.结果:黄芪、雷公藤多甙各不同剂量组均可抑制肾小球系膜细胞产生IL-6,其抑制作用随剂量增加而增殖,其中尤以雷公藤高剂量组、中剂量组及黄芪高剂量组作用明显.结论:黄芪可抑制肾小球系膜细胞分泌IL-6,这一作用与雷公藤类似.这可能是黄芪防治肾小球硬化的作用机制之一.     

Palatal implants: a new approach for the treatment of obstructive sleep apnea.

OBJECTIVE: To evaluate the short-term safety and efficacy of palatal implants in patients with mild and moderate obstructive sleep apnea (OSA). STUDY DESIGN AND SETTING: A prospective, non-randomized study conducted at 5 clinical sites. Three polyester implants were placed in the soft palate under local anesthesia during a single-stage office procedure. Polysomnography was conducted at baseline and 90 days post-procedure. Subjective quality of life data were collected. RESULTS: Fifty-three patients were evaluated; the apnea hypopnea index (AHI) decreased from 25.0 +/- 13.9 to 22.0 +/- 14.8 events/hour (P = 0.05). The Epworth Sleepiness Scale (ESS) decreased from 11.0 +/- 5.1 to 6.9 +/- 4.5 (P < 0.001), and the snore score decreased from 7.9 +/- 2.1 to 4.0 +/- 3.0 (P < 0.001). No serious complications occurred during the study. CONCLUSION: Palatal implants can be an effective initial low morbidity treatment option for patients diagnosed with mild to moderate OSA.
