高中生常见心理问题及对策

高中阶段是青少年身心发展的重要时期,是青少年思想品质、人生观、自我意识、情绪情感、个性、人格等形成的关键时期。处于这个时期的高中生,其心理的发展具有成熟和幼稚、独立和依赖、自觉和盲动等诸多矛盾并存的特点,易产生各种各样的心理和行为问题。近几年来,中学生的心理健康问题,已引起了全社会的关注,对高中生心理问题的研究也越来越多。大量调查研究证实:高中生心理问题的检出率在10%~30%之间[1],高中生心理健康问题不容忽视。1高中生常见心理问题1·1自我认知不正确自我认知是指正确客观的认识和评价自我,是自我意识的主要内容。心…

[Ca^2＋]i change in hippocampal neurons influenced by preconditioning of etomidate fat emulsion following cerebral ischemia in rats

BACKGROUND: It is known that intravenous anesthetic etomidate fat emulsion has cerebral protection. Now many scholars focus on the research of its cerebral protection from molecular biology, but the mechanism of cerebral protection is still fully unclear. OBJECTIVE: To observe the influence of etomidate fat emulsion on the [Ca2+]i in hippocampal neurons during the transient cerebral ischemia injury in rats. DESIGN: Randomized controlled observation. SETTING: Weifang Medical College. MATERIALS: This study was carried out in the functional laboratory of Weifang Medical College between October 2005 and March 2006. Twenty-four male healthy Wistar rats, aged 3 to 4 months, were involved. Etomidate fat emulsion was provided by the limited company of En-hua Medical Bloc in Jiangsu Province (code of H20020511) and the other agents and materials were provided by Laboratory Center of Weifang Medical College. METHODS: The 24 Wistar rats were randomized into 3 groups: sham-operation group, model group and etomidate preconditioning group, with 8 rats in each. Rat models of transient cerebral ischemia injury were made by the ligation of bilateral carotid arteries combined with descending blood pressure in the latter two groups. Before ischemia (ligation of bilateral common carotid artery), rats in the etomidate preconditioning group were intraperitoneally injected with 12 mg/kg etomidate fat emulsion and then persistently intraperitoneally injected with etomidate fat emulsion at 1.0 mg/kg per minute. Rats in the model group were not administrated. Rats in the sham-operation group were only performed bilateral common carotid artery isolation. When rats were modeled, their brain tissues were quickly taken out and detected. MAIN OUTCOME MEASURES: Change of the fluorescence pixel value of the [Ca2+]i in each group by the laser scanning confocal microscope. RESULTS: Twenty-four rats were involved in the final analysis. Fluorescence pixel value in the sham-operation group was in the low level. Fluorescence pixel value in the model group was significantly higher than that in the sham-operation group (P < 0.01). Fluorescence pixel value in the etomidate preconditioning group was significantly lower than that in the model group (P < 0.01). CONCLUSION: The protection of etomidate fat emulsion to the transient cerebral ischemic injury in rats is associated with the inhibition to the increase of [Ca2+]i to some extent.     

冠心病患者CRP水平与肾动脉狭窄的关系

【论文特点介绍】本研究观察了CRP是否可以作为肾动脉粥样硬化狭窄（ARAs）的独立危险因子。通过对危险因素进行多变量Logistic回归分析，结果表明年龄、冠脉病变严重程度、外周血管疾病是ARAS的独立危险因素，而CRP水平、高血压、高脂血症、肾功能不全并非ARAS的独立危险因素。     

妊娠高血压综合征尿蛋白的丢失对新生儿出生体重的影响

目的: 几乎没有研究报道妊娠高血压综合征 (妊高征 ) 患者尿蛋白对新生儿出生体重的影响, 该研究欲探讨妊高征患者不同水平尿蛋白对新生儿出生体重的影响关系。方法: 1997年 1月 ~2004年 6月期间, 住院分娩患中、重度妊高征产妇 136例, 对新生儿出生体重与各种因素进行回归分析及t检验分析。结果: 单变量回归分析尿蛋白、孕龄分别与新生儿出生体重有高度显著性关系 (P<0. 01); 尿蛋白和孕龄一起进入多元回归分析, 校正影响因素, 尿蛋白和孕龄仍然是影响新生儿出生体重显著性因素 (P<0 .01); 与妊高征尿蛋白 ( +) 比较, 尿蛋白 无显著性影响新生儿出生体重 (P>0. 05), 尿蛋白 有显著性影响新生儿出生体重 (P<0. 01)。结论: 新生儿出生体重与妊高征患者尿蛋白丢失有关, 尿蛋白 丢失将严重影响新生儿出生体重。     

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.
