The new wind wave growth relations (WWGRs) are analytically derived with sheltering coefficient and wind drag coefficient as parameters. The geometrical average of observational values of sheltering coefficient and the arithmetic average of observational values of wind drag coefficient are applied to determine the new WWGRs. Comparisons with existing empirical WWGRs are made.展开更多
目的探讨P53基因与鼻腔鼻窦内翻性乳头状瘤(SNIP)恶变的关系。方法选用Pubmed、Web of science、Embase、Cochrane Library、CNKI、维普、中国知网及万方等数据库(1998-2017)检索国内外发表的P53基因表达与SNIP关系的病例对照研究,应用R...目的探讨P53基因与鼻腔鼻窦内翻性乳头状瘤(SNIP)恶变的关系。方法选用Pubmed、Web of science、Embase、Cochrane Library、CNKI、维普、中国知网及万方等数据库(1998-2017)检索国内外发表的P53基因表达与SNIP关系的病例对照研究,应用Rev Man5.3统计软件对各研究的原始数据进行统计分析。结果Meta分析示恶变组P53阳性率明显高于SNIP组(P0.05,OR=1.37,95%CI为0.59~3.20);SNIP组P53阳性率与对照组无明显差异(P=0.47>0.05,OR=5.32,95%CI为0.78~36.39)。结论P53的异常表达与SNIP的恶变密切相关,而与SNIP的发生及复发无关。展开更多

Although anti-retroviral drugs are effective, yet too expensive, the majority of 600 000 Chinese patients can't afford to purchase and use them. Decades ago, some scientists were trying to use Chinese Medicine in treating AIDS, experienc e gained but problems also exposed concerning strategy of research, methodol ogy, racial difference, Chinese drugs screening, integrative Chinese and western medicine, HIV and immunity, etc., sustained and integrative effort would bring safe, effective, and affordable drugs for the fatal pandemic all over the world ……展开更多
