针刺对急性心肌缺血大鼠血清NO、血浆ET-1、NO/ET-1比值的影响

目的探讨针刺华佗夹脊穴改善急性心肌缺血的作用机制。方法采用大剂量盐酸异丙肾上腺素(ISO.100mg/kg)皮下注射建立大鼠急性心肌缺血模型。选健康SD大鼠40只,随机分为针刺治疗组、针刺预防组、模型组和空白对照组。观察针刺左侧胸4、胸5夹脊穴及左侧足三里穴对急性心肌缺血大鼠血清一氧化氮(NO)、血浆内皮素-1(ET-1)及NO/ET-1比值及ECG的影响。结果针刺治疗能够提高急性心肌缺血大鼠血清NO的含量,降低其血浆ET-1的含量,从而提高NO/ET-1比值。结论针刺华佗夹脊穴具有改善急性心肌缺血大鼠的血管内皮功能,在一定程度上纠正内皮功能紊乱的作用。针刺预防的上述作用不明显。     

Longitudinal Analysis of Severe Acute Respiratory Syndrome (SARS) Coronavirus-Specific Antibody in SARS Patients

The serum antibodies to severe acute respiratory syndrome (SARS) coronavirus of 18 SARS patients were checked at 1 month and every 3 months after disease onset. All of them except one, who missed blood sampling at 1 month, tested positive for the immunoglobulin G (IgG) antibody at 1 month. Fifteen out of 17 tested positive for the IgM antibody at 1 month. The serum IgM antibody of most patients became undetectable within 6 months after the onset of SARS. The IgG antibody of all 17 patients, whose serum was checked 1 year after disease onset, remained positive.

目的 探讨体重指数(BMI)、腰围(WC)、腰臀比(WHR)与代谢性因素的关系.方法 对镇江市居民基线资料的1108例对象按BMI、WC、WHR分组.在正常体重、超重、肥胖;腰围正常、腰围过大;腰臀比正常、腰臀比过大各组中,比较收缩压(SBP)、舒张压(DBP)、血糖(FBG)、总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)的水平.结果 不论男性女性组,超重肥胖、腰围过大组,血压、血糖、血脂水平与正常组比较均明显升高;腰臀比过大组与正常组比较,男性组TG、FBG明显升高;HDL-C明显降低;女性组TG、FBG、SBP明显升高,HDL-C明显降低.结论 BMI、WC、WHR指标与代谢性因素密切相关;BMI、WC在提示肥胖程度方面优于WHR指标.     

多站点综合性毕业考试的改革与实践

我校改革临床医学专业毕业考试模式与方法，在临床实习过程中组织多站点综合性考试，采用闭卷笔试方法考核临床理论知识，占70％；采用实践操作与现场口试方法考核临床技能及相关知识，占20％；采用开卷笔试方法考核医疗文书书写，占10％。实践证明，此项改革能促进医学生端正实习态度，调动实习的积极性与主动性，引导医学生在实习中重视理论学习与临床实践的密切结合，促进临床教学质量的提高。     

Fas和mdr-1在急性白血病的表达及其相关性研究

本研究应用流式细胞仪 (FCM)直接免疫荧光法和半定量RT PCR方法分别测定 5 9例初发急性白血病(AL)患者治疗前及完全缓解 (completeremission ,CR)后骨髓Fas和mdr 1mRNA表达情况 ,旨在探讨Fas和mdr 1在AL的表达及二者在多药耐药 (multidrugresistance ,MDR)中的相关性。结果显示 :Fas在初发AML阳性表达率比ALL高 ,两表达率间有差异 (P <0 .0 5 ) ,mdr 1在AML和ALL阳性表达率间无差异 (P >0 .0 5 ) ,Fas 与mdr 1 有负相关性 (r =- 0 .2 82 ,P <0 .0 5 ) ;经单因素及多因素COX分析 ,Fas和mdr 1独立于其他参数 ,更具判断预后价值 ;在Fas 与Fas-的AML和AL ,CR率均有显著性差异 (P <0 .0 1) ,在mdr 1 、mdr 1-的AML和AL中的CR率有显著性差异 (P <0 .0 1) ;经Logrank检验 ,Fas 与Fas-组CR率及中数缓解时间有显著性差异 (χ2 =7.35 ,P =0 .0 0 6 7) ,mdr 1 与mdr 1-组CR率及中数缓解时间有显著性差异 (χ2 =10 .71,P =0 .0 0 11)。结论 :Fas、mdr 1与疗效高度相关 ;Fas阳性表达可能是AL预后良好因素 ;mdr 1为疗效差、预后不良的重要因素。     

Buccal mucosal graft for urethral reconstruction.

Urethral reconstruction with graft substances, such as skin and bladder mucosa, has been previously used when primary anastomosis cannot be achieved. However, stricture and meatal prolapse are associated with these grafts. We report the use of buccal mucosa for the reconstruction of urethral defects in 3 patients. One patient with failed operation for hypospadias received tube buccal mucosal graft for urethral replacement. Two patients with urethral necrosis and stricture received onlay buccal mucosal graft. All patients were disease-free during follow-up (range, 12 to 49 months; mean, 36 months). One patient had a pinhole fistula that was successfully managed with simple repair. This technique appears to be useful for urethral reconstruction when a local graft is not available, even in patients with complicated conditions.     

富氧对海拔3700m高原人体运动心力储备的影响

目的　探讨富氧对高原人体运动心力储备方面的影响。方法　对海拔 3 70 0m高原的 1 2名健康青年富氧 (氧浓度为 2 4%～ 2 5 %)前后分别进行踏阶运动 ,采用心力监护仪采集和记录心动周期和心力信息 ,把完成规定运动量运动后第一心音 (S1 )幅值对安静时S1 幅值增加的相应倍数评估心肌收缩能力储备指数 (CCRI) ;利用舒张期和收缩期时限数据计算舒张期 /收缩期比值 (D/S比 )。结果　运动后较安静时HR ,D/S ,S1 幅值均增高 ,有非常显著性差异 (P <0 .0 1 ) ;富氧运动较未富氧运动CCRI,D/S ,S1 幅值增高 ,有显著性差异 (P <0 .0 5 ) ,HR无统计学意义 (P >0 .0 5 )。结论　高原低氧环境下心脏储备主要是心肌收缩能力储备而不是心率储备。富氧对增强机体心力储备具有重要作用     

Adolescent violence.

The purpose of this document is to provide an overview of the rising occurrences of adolescent violence in the American school systems and how various theories can be used to assist in understanding this phenomenon. The authors have become increasingly interested in this topic, after direct involvement in the summer of 2001. There were a number of students who were attending summer school as a result of consistent out-of-school suspensions for violent acts. The procedure to process through the system with these students was to suspend them, resulting in the student subsequently failing their present grade. The school was located in a community known for its high rate of violence and criminal activity. Various types of adolescent violence exist in our schools. Studies have reported that violent adolescents may come from familial environments that are full of social and interpersonal conflicts (Gray & Foshee, 1999). This paper discusses the development of a research plan to investigate the number and type of adolescent violent occurrences in a southern middle school setting.     

持续靶控输注异丙酚复合硬膜外麻醉用于上腹部手术探讨

目的:评价持续靶控输注异丙酚复合硬膜外阻滞有用于上腹部手术的可行性。方法:30例胃癌手术患者,ASAⅠ～Ⅱ级。随机分成靶控输注异丙酚全麻(T)组15例,靶控异丙酚复合硬膜外阻滞(T+E)组15例。结果:(T+E)组术后躁动、芬太尼、丙泊酚的用量低于(T)组(P<0.05)。异丙酚单位标准化剂量亦较低。两组苏醒时间相似。诱导后两组血压均显著下降(P<0.05),T+E组在诱导后DBP的下降幅度较T组更为显著(P<0.05),T组在探查、术毕、拨管后的SBP、DBP、MAP比(T+E)组显著增高(P<0.05)。两组诱导后至术毕BIS、SEF显著下降,两组间的比较无统计学意义(P>0.05)。结论:靶控输注异丙酚复合硬膜外阻滞用于上腹部手术是可行的,具有异丙酚、芬太尼的用量少、苏醒快、术后躁动少,麻醉深度易于调控,血液动力学较稳定,是一种良好的麻醉方式。
