奥沙利铂持续腹腔热灌注治疗癌性腹水的临床研究

目的研究奥沙利铂(L-OHP)持续腹腔热灌注治疗癌性腹水的疗效和毒副作用。方法将76例癌性腹水患者随机分为三组:奥沙利铂持续腹腔热灌注化疗组(热化组)26例,引出腹水后,在加热的5%葡萄糖溶液2500～3500ml中加入L-OHP200mg/m2,持续体外循环腹腔热灌注,腹腔内温度保持在41～43℃,持续60min;腹腔内注射奥沙利铂化疗组(单化组)26例,常规腹腔穿刺引流腹水后注射L-OHP200mg/m2。单纯腹腔热灌注组(单热组)24例,加热5%葡萄糖溶液2500～3500ml,持续热灌注60min。结果总有效率(CR PR)54%(41/76)。热化组、单化组和单热组的有效率分别为76.9%(20/26)、50.0%(13/26)、33.3%(8/24),P<0.05。急性腹痛:热化组53.8%(14/26),单热组16.7%(4/24)。单化组无急性腹痛病例,P<0.05。麻痹性肠梗阻:热化组19.2%(5/26),单化组7.7%(2/26),单热组16.7%(4/24),P>0.05。结论奥沙利铂持续腹腔热灌注治疗恶性腹水是一种新的有效的治疗方法,毒副作用不大。

Structured training of ENT Specialist Registrars in the out‐patient clinic and theatre

The aims of this paper are to evaluate the training in out‐patients and in theatre after the recent changes in SpR training. A postal questionnaire was sent to 191 Specialist Registrars (SpRs) in England and Wales and 57 were returned (30%). There were temporal bone facilities within the hospital for 53 SpRs but only three used them because there were no temporal bones. Surgical training was more satisfactory than out‐patient training. Fewer general clinics and more specialized clinics are required, and consultant supervision is still patchy and needs attention.     

Immunological outcomes of exercise in older adults

Aging is associated with a dysregulation of the immune system known as immunosenescence. Immunosenescence involves cellular and molecular alterations that impact both innate and adaptive immunity, leading to increased incidences of infectious disease morbidity and mortality as well as heightened rates of other immune disorders such as autoimmunity, cancer, and inflammatory conditions. While current data suggests physical activity may be an effective and logistically easy strategy for counteracting immunosenescence, it is currently underutilized in clinical settings. Long-term, moderate physical activity interventions in geriatric populations appear to be associated with several benefits including reduction in infectious disease risk, increased rates of vaccine efficacy, and improvements in both physical and psychosocial aspects of daily living. Exercise may also represent a viable therapy in patients for whom pharmacological treatment is unavailable, ineffective, or inappropriate. The effects of exercise impact multiple aspects of immune response including T cell phenotype and proliferation, antibody response to vaccination, and cytokine production. However, an underlying mechanism by which exercise affects numerous cell types and responses remains to be identified. Given this evidence, an increase in the use of physical activity programs by the healthcare community may result in improved health of geriatric populations.     

运动训练联合基因治疗对肾性高血压大鼠肾功能的影响

目的观察运动训练联合β1肾上腺素能受体基因治疗对肾性高血压大鼠血压、肾功能、肾脏前肾素原mRNA、肾脏β1受体mRNA和蛋白的影响，探讨其改善肾功能的机制。方法两肾一夹法制作肾性高血压模型，基因治疗采用经鼠尾静脉注射阳离子脂质体与β1反义寡核苷酸方法。检测大鼠血压、肾功能变化。半定量RT—PCR测定肾脏β1受体mRNA、前肾素原mRNA水平。Western印迹法测检肾脏β1受体的蛋白水平。结果与模型组比较，运动联合基因治疗可使血压下降并维持4周，血压下降最高达41mmHg；尿蛋白量[（45．82±6．56）比（29．12±5．22）mg／L，P〈0．01】、BUN[（13．10±2．62）比（9．05±1．84）mmol／L，P〈0．05]显著降低（P〈0．01，P〈0．05）；内生肌酐清除率显著升高（P〈0．01）；前肾素原mRNA、β1受体mRNA、蛋白表达水平显著降低（P〈0．05）。结论运动训练联合β1受体反义基因治疗可以明显地降低血压，改善肾功能；且运动训练可以增强基因治疗对β1受体mRNA和蛋白的抑制作用，在转录和翻译水平抑制过度激活的β1受体的表达。     

连续浅缝法修补膜周型室间隔缺损

目的探讨连续浅缝法修补单纯膜周型室间隔缺损(pVSD)法的效果。方法选取2002年1月至2004年10月我院收治的体重10kg以内(≤10kg)50例单纯膜周型室间隔缺损患者,均采用自体心包连续浅缝法修补。结果主动脉阻断时间32±21min(14-52min),体外循环时间56±35min(29-69min)。无°房室传导阻滞发生,9例发生右束支传导阻滞,2例结性心律。2例膜周偏流出道型VSD患者因前上缘残余分流分别为0.4cm和0.3cm,再次手术修补;1例后下缘残留细束样分流,直径0.15cm,随访6个月后自愈;10例膜周偏流出道型VSD患者剪开三尖瓣,8例垂直瓣环,2例平行瓣环;1例三尖瓣中度反流,随访无加重;5例轻度反流,4例轻微反流,随访均无加重;1例心包积液;1例再次进入手术室止血。结论连续浅缝法是修补单纯膜周型室间隔缺损的有效外科纠治方法。     

An inexpensive ex-vivo porcine laparoscopic Nissen fundoplication training model.

BACKGROUND: We recently implemented the use of an ex-vivo porcine model to teach residents the fundamentals of performing a laparoscopic Nissen fundoplication. METHODS: Residents were trained using intact porcine esophagus, stomach, and spleen placed in a standard video-trainer. They were later asked to complete a survey containing a course evaluation. RESULTS: Sixteen residents (R1-R4) completed the survey. They agreed that (1) the exercise was a valuable use of their limited time, (2) repeating the exercise will be of additional benefit, (3) it will improve their ability to perform or assist in an actual case in the OR, and (4) the surgical principles learned using the model will transfer to other laparoscopic cases. Significant subjective improvements were reported in resident comfort level in assisting in or performing a laparoscopic Nissen fundoplication. CONCLUSIONS: The use of an inexpensive ex-vivo porcine training model increases resident comfort level in performing a Nissen fundoplication in the operating room.
