Zhao Yufeng, a celebrated painter on modern fine brush ink color, was born of a farmer family in Guxian County, northern Shanxi Province in 1942. Graduating from Shanxi Art Academy, Zhao is currently member of Beijing Artists Association and Beijing Modern Fine-brush Ink Color Painting Society. Zhao has dedicated herself to Chinese ink painting and scored remarkable achievements. She said, ＂It is my most willing choice to take painting as my lifetime career.＂     

细胞遗传工程:植物育种的一项新技术吗?

有一项道传工程的新技术,它不象重组DNA技术那样被广为宣传,那就是通过无性细胞融合来转移遗传物质。采用这一有前途的方法交换整块基因,不必象在重组DNA技术中那样需事先进行鉴定和分离。今后几年内,这类方法可使基因块(geneblock)从一物种转侈到另一物种成为可能,例如可以把杂草的抗除草剂抗性赋予农作物。

运动员的自我效能与运动信心模式的理论分析

运用献资料法，介绍了认知运动心理学中的两个重要理论：班都拉的自我效能和堆利的运动信心模式．并对二从定义上及其与归因、竞技定向、行为的关系作了比较分析，尽管班都拉的自我效能理论在国外运动心理学界广泛应用．但维剩的运动信心模式更易于被中国的教练员和运动员所接受。

Human biochemical genetics： an insight into inborn errors of metabolism

Inborn errors of metabolism （IEM） include a broad spectrum of defects of various gene products that affect intermediary metabolism in the body. Studying the molecular and biochemical mechanisms of those inherited disorder, systematically summarizing the disease phenotype and natural history, providing diagnostic rationale and methodology and treatment strategy comprise the context of human biochemical genetics. This session focused on： （1） manifestations of representative metabolic disorders; （2） the emergent technology and application of newborn screening of metabolic disorders using tandem mass spectrometry; （3） principles of managing IEM; （4） the concept of carrier testing aiming prevention. Early detection of patients with IEM allows early intervention and more options for treatment.     

A probiotic treatment containing Lactobacillus, Bifidobacterium and Enterococcus improves IBS symptoms in an open label trial

INTRODUCTION Irritable bowel syndrome (IBS) is the most common functional gastrointestinal disorder. The typical symptoms are abdominal pain, flatulence, and irregular bowel movement. Prevalence rates are re- ported to be as high as 30% in the general population (Drossman et al., 1982), corresponding to about 25%~50% of all patients who need gastroenterolo- gist’s help (Everhart and Renault, 1991). Despite this high prevalence, the cause of IBS is unknown. Many factors are likely to …     

Research on the protection effect of pioglitazone for non-alcoholic fatty liver disease （NAFLD） in rats

Objective： The prevalence of non-alcoholic fatty liver disease （NAFLD） has markedly increased. Insulin resistance has been implicated in the pathogenesis of NAFLD. This study was aimed at observing the relationship between insulin resistance and NAFLD, and evaluating the role of pioglitazone （PGZ） acting as insulin-sensitizing agents in the prevention and treatment of rat fatty liver induced by high fat feeding. Methods： The rats were separated randomly into 6 groups： model group Ⅰ were fed high fat diet for 8 weeks, PGZ prevention group were given PGZ 4 mg/（kg.d） simultaneously, while control group Ⅰ were fed normal food for 8 weeks; model group Ⅱ were fed high fat diet for 16 weeks, PGZ treatment group were given PGZ 4 mg/（kg.d） orally simultaneous with high fat diet for 8 weeks after high fat feeding for 8 weeks, control group Ⅱ were fed normal food for 16 weeks. The rats were sacrificed after 8 weeks and 16 weeks respectively. Liver weight, body weight, serum activities of alanine aminotransferase （ALT）, aspartate aminotransferase （AST）, alkaline phosphatase （ALP）, tumor necrosis factor alpha （TNF-α）, fasting blood glucose （FBG）, fasting plasma insulin （FINS）, HOMA （homeostasis model assessment） insulin resistance index （HOMA-IR）, and the liver histology of rats of all groups were assayed. Results： After 8 weeks, the liver in model group Ⅰ showed typical steatosis, accompanied with mild to moderate lobular inflammatory cell infiltration, liver indexes and serum levels of ALT, AST, ALP, TNF-α were significantly increased （P〈0.05） compared with control group Ⅰ. Whereas, the degree of hepatic injury was attenuated in PGZ prevention group, liver indexes and serum levels of ALT, ALP were significantly decreased （P〈0.05） compared with model group Ⅰ. After 16 weeks, notable steatosis, and lobular inflammation were observed in model group Ⅱ rat liver, while the degree of hepatic injury was attenuated in the PGZ treatment group. Liver index, serum levels ofALT, AST, ALP, FINS and HOMA-IR were significantly increased （P〈0.05） in model group Ⅱ compared with control group Ⅱ. Whereas, in PGZ treatment group, serum levels of AST and FINS showed decreasing tendency, liver indexes, serum levels of ALT, ALP, TNF-α and HOMA-IR were significantly decreased compared with model group Ⅱ. Conclusion： Insulin resistance plays a role in the pathogenesis of NAFLD in rats. Pioglitazone can attenuate insulin resistance and biochemical and histological injury in high fat-induced fatty liver in rats.
