The irregular wave experiment on the stability of the Grate Plate was carried out in the light of the wind wave spectrum recently advanced by Prof. Wen Shengchang. The stability formulas of GP under the action of irregular waves were procured. Comparisons between the formulas obtained and those of GP under regular waves advanced by the first author in 1993 showed a coincident result.

NITRIC oxide (NO) is the important cell messenger molecule that regulates the central ner-vous, cardiovascular, endocrine and immunity systems. The study of NO not only canexplain many physiological phenomena, but also can provide new ways to prevent and treat alot of diseases. However, at present, most of the methods for assaying NO produced by or-ganism have some defects, for example, low sensitivity, no specificity, no convenience.

AIM: To re-evaluate the algorithm that has been used forover 40 years for diagnosis of acute abdominal pain ***: Among the 937 cases admitted to the surgicalemergency ward in 2000, 656 cases of acute appendicitiswere studied to evaluate the usefulness of the presentalgorithm for its colculated accuracy, false positive and falsenegative rates, the sensitivity and specificity in the instantdiagnosis of various types of acute appendicitis in differentage *** algorithm used was established in 1958and revisedror this study in 1999. It includes a 3-step analysisof clinical presentations, i.e.: firstly, a diagnosis of surgicalpain by definite organic abdominal signs; then a diagnosisof the subgroup of surgical condition by special signs; andfinally the diagnosis of the present disease by specific signs.A footnote describes a 'comparative technique″ of abdominalexamination in non-cooperative ***: The general accuracy of diagnosis was 92.8 %,overall mortality 0.1% among 973 cases of abdominal painin 2000. 373 attending surgeons and 241 residents includingtrainees joined the diagnosis and treatment with noremarkable difference in the results. The incidence of acuteappendicitis, 656 in 973 cases, was 67.4 % representingthe majority of abdominal pain. In the series of 656 cases,the accuracy of diagnosis of acute appendidtis was 93.6 %,false positive 6.4 %, false negative 0.9 %, sensitivity at firstvisit 82.7 %, specificity for appendicitis 98.0 %, no death ordocumentary ***: The present algorithm used for diagnosisof acute abdominal pain is effective and preferable inreducing misdiagnosis and maltreatment at emergency. Theuse of some modern technology should be further explored.

在肝细胞癌(HCC)发生发展过程中,伴随着原癌基因和抑癌基因的突变,各种参与调控的细胞因子表达也发生异常并最终影响疾病的进程和转归．目前对肝细胞癌的分子病理学研究已经集中在这些细胞因子的异常表达及其相互关系网络上,HBx蛋白、SAM、TGF等细胞因子的研究已经十分深入。而且,随着各种新技术的应用,更多的低丰度调控蛋白也逐渐被发现,其在肝细胞癌细胞增殖调控、异常分化、衰老和凋亡调节以及肿瘤演进等方面起着重要作用．
