肝细胞癌合并胆管癌栓患者术中癌栓的处理

目的 探讨肝细胞癌（HCC）合并胆管癌栓患者术中癌栓的处理方式和术后恢复过程。方法 对1995年1月-2002年12月手术治疗的27例HCC合并胆管癌栓情况进行回顾性总结和分析。结果 只有59．3％（16／27）患者行肝切除、胆管取癌栓及胆管引流术。全组术后并发症发生率为55．6％（15／27），术后30d病死率为22．2％（6／27）。结论 HCC合并胆管癌栓的预后差，早期诊断和外科手术治疗是改善此病预后的关键。     

昆虫色氨酸羟化酶的研究进展

色氨酸羟化酶（tryptophan hydroxylase、TPH）为5-羟色胺（5-hydroxytryptamine，5-HT）合成的限速酶，具有专一性，在组织中含量较低，且具有不稳定性。TPH的活性是5-HT合成的唯一前提，因此它可以作为5-HT能神经元的特异标志，也可以作为5-HT能神经元的一个分化特征。它的存在，住区分神经细胞特征方面比5-HT本身的含苗更有价值。因而近年来TPH迅速成为国际研究的热点和难点之一。本文主要就TPH在昆虫中的存在形式、调节机制及进化地位等方面已取得的研究进展作一简述。     

乙肝歧视,大学校园该亮起的红灯

目的:通过调查在校大学生对乙肝的认知程度,使其了解乙肝的传播途径,并针对由乙肝认知误区所引起的大学生乙肝歧视进行讨论,得出相应解决措施,积极创建和谐校园。方法:采用问卷调查的方式对在校的非医学生和医学生进行调查。结果:调查发现,很多大学生都对乙肝有了正确的认知态度,理解了与乙肝患者的平等性。相对较多的大学生对乙肝患者或是乙肝病毒携带者没有明显的生活上的排斥,但是心里仍存在一定的恐惧和歧视。结论:乙肝歧视仍存在于当代大学生之间,要使整个社会对乙肝歧视有所消除,大学生首当其冲要作好消除乙肝歧视,发展和谐校园,让乙肝歧视在校园中亮起红灯。     

Influence of moderate hypothermia on cerebral oxygenation in pigs with intracranial hypertension

BACKGROUND: Moderate hypothermia is one of the effective therapeutic methods for head injury in recent years, there are many mechanisms of moderate hypothermia for brain protection, and its influence on cerebral oxygenation is also one of them. OBJECTIVE: To observe the influence of moderate hypothermia on cerebral oxygenation of animals with acute intracranial hypertension, and further investigate the protective mechanism of moderate hypothermia. DESIGN: A randomized controlled trial. SETTING: Department of Neurosurgery, Renji Hospital affiliated to the Medical College of Shanghai Jiao Tong University. MATERIALS: Twenty healthy little pigs, either male or female, weighing 4.5–5.5 kg, were used. Neurotrend-typed multiparameter monitoring system (Diametrics Company, British); CMA/100 micro-injection pump (Carnegie Company, Sweden). METHODS: The experiment was conducted in the Changzheng Hospital affiliated to the Second Military Medical University of Chinese PLA in November, 2001. The pigs were randomized into two groups: the normothermia group (control group, n =10) and moderate hypothermia group (n =10). ① Bilateral femoral arteries were separated, one was connected to pressometer for monitoring mean arterial pressure (MEP), and the other for analysis of blood gases [including peripheral blood pH value, arterial partial pressure of carbon dioxide (PaCO2), arterial partial pressure of carbon dioxide (PaCO2), HCO3–]. ② Rectal temperature was monitored with mercurial thermometer. ③ Intracranial pressure was monitored using Camino optic ICP probe placed in the subdural space. ④ Neurotrend multiparameter monitoring sensor was inserted into the white matter for about 4 cm to determine cerebral perfusion pressure (CPP, CPP=MAP(ICP), brain tissue partial oxygen pressure (PO2), partial pressure of carbon dioxide (PCO2), HCO3– and brain temperature. The rectal temperature of animals in the moderate hypothermia group was lowered to 34 ℃ using ice bags, and the body temperature was maintained at 33–35 ℃ for 2 hours. The changes of the parameters were observed continuously, and the pigs in the normothermia group were not treated with cooling. MAIN OUTCOME MEASURES: ① MAP, ICP, rectal temperature, CCP; Indexes of cerebral oxygenation detected with Neurotrend-typed multiparameter monitoring system; ② Results of blood gases analysis in the moderate hypothermia group. RESULTS: All the 20 pigs were involved in the analysis of results. ① MAP, ICP, rectal temperature, CCP and indexes of cerebral oxygenation: In the moderate hypothermia group, the ICP after cooling was obviously lower than that before cooling [(3.31±1.19), (5.33±0.95) kPa, P < 0.05], CCP was higher, brain tissue PCO2 [(12.03±1.73), (10.59±2.01) kPa, P < 0.05], and brain tissue pH value was higher [(7.03±1.63), (9.40±1.30) kPa, P < 0.05], whereas the brain temperature was decreased as compared with that before cooling [(34.9±0.3), (37.2±0.2) ℃, P < 0.05]. ② Results of blood gases analysis in the moderate hypothermia group: There were no significant differences in the parameters of peripheral arterial blood gases analysis before and after cooling in the moderate hypothermia group (P > 0.05) CONCLUSION: Moderate hypothermia will not impair the cerebral oxygenation, and it can reduce brain tissue CO2 and decrease brain tissue acidosis.

Observations on pathological and histochemical changes in piglet livers infected with Taenia saginata asiatica

To study the pathological and histochemical characteristics of lesions in piglet livers infected with Taenia saginata asiatica (T. saginata asiatica) throughout the different stages, piglets were fed with eggs of T. saginata asiatica and raised in isolation in an animal center to establish the T. saginata asiatica infection model with normal piglets as control. The pathological changes in the piglet livers were observed after the infection using liver sections stained with hematoxylin and eosin. Histochemical methods were used to check the changes in lipid, glycogen and protein content in the liver. The data collected by image analysis were analyzed statistically with Statistical Package for the Social Science. The results show that T. saginata asiatica-exposed piglets were indeed infected. Inflammatory reactions began on the fourth day and progressed rapidly. Kupffer cell hyperplasia, hepatic hydropic degeneration and ballooning degeneration were found in the 10th–20th days after infection. Hepatic central veins and hepatic sinusoids were dilated and congested. Spotty necrosis occurred in some local liver tissues. In the 40th–60th days, granulomatous reactions and mild hepatocirrhosis were the main lesions. In the 70th–80th days, hepatocirrhosis and bile duct proliferation were observed in the liver. In the different stages, lipid drops were increased while glycogen and protein levels were decreased to some degree. There was a significant difference in metabolism between the infected group and the control group (P < 0.01). It is concluded that pigs are the favorable intermediate host of T. saginata asiatica and its infection can result in serious pathological and histochemical lesions in host organs.

智力残疾的适应性行为评估

适应性行为评估是智力残疾诊断与干预的必要依据。适应性行为的概念至今仍未有统一的观点，AAMR（2002）认为，适应性行为指的是概念、社会和应用3方面的技能，它的限制会影响个体的日常生活运作，进而影响其生活适应。对适应性行为进行评估的方法主要有测验法、行为观察法、功能性评估、生活质量评估和社会技能测量。无论使用什么方法进行评估，都应当以改善智力残疾个体现有状况为目的，考虑到各种评估方法的局限性，对智力残疾个体宜进行全面评估。
