In industrial countries such as America and European countries, there are national or local FAP familial registration centers offering screening and follow-up for families of FAP patients, which has significantly lowered the incidence of colorectal carcinoma and apenteric cancers.

在美国及西欧等发达国家都建立了全国或区域性FAP家系登记中心，对家系成员进行筛选和随访，显著降低了这类群体中大肠癌以及肠外恶性肿瘤的发生率。

We therefore carried out a series of studies in 22 FAP patients who were admitted in Changhai Hospital between 2001 and 2003, which included examination of enteral and apenteric lesions, investigation of family lines and postoperative follow-up observation.

我们对本科室在2001～2003年收治的22例患者进行大肠内、外病变的观察、家系调查以及治疗后随访观察，结合1985～2000年我院96例患者临床资料回顾性分析：包括临床特征、诊断方法、家系筛选以及手术方式、随访结果等进行分析总结，并对FAP临床诊治作了进一步探讨。

In addition, the clinical data of 96 FAP cases clinically diagnosed between 1985 and 2000 were analyzed retrospectively, which included clinical (enteral and apenteric manifestations, methods of diagnosis and screening, surgical modality and follow-up findings).

我们认为结肠镜是FAP最可靠、最有效的临床诊断方法并在家系成员筛选中可发挥重要作用；CHRPE是具有高度特异性和敏感性的辅助诊断方式，可作为对未成年家系成员筛选的首选方法；FAP常伴发上消化道病变包括胃窦部增生性息肉，十二指肠腺瘤发病率高，但癌变少见；腹腔硬纤维瘤是FAP的严重结肠外病变，术后复发率高；FAP术后如直肠粘膜有残留，其腺瘤复发及癌变危险性高，应定期结肠镜随访。

I had buttoned up the collar and tied the belt, apronlike, in back. Momma told me to turn around.

25我已经扣上了领子，腰带也像系围裙带那样在背后系好了。

However, the taxa of strictly tropical distribution are still underrepresented in the flora of southeastern Yunnan compared to Indo-Malaysian flora, and the families of mainly subtropical to temperate distribution, such as Magnoliaceae, Theaceae, Cornaceae, Styracaceae, Symplocaceae, Aquifoliaceae and Caprifoliaceae, are well represented in the flora. Some characteristic families of temperate East Asia, such as Diapensiaceae, Dipentodontaceae, Eupteleaceae, Grossulariaceae and Toricelliaceae are also present in the flora of southeastern Yunnan.

由於位於东南亚热带北缘山地及其地质历史原因，云南东南部的热带植物区系中严格热带分布的成分不多，仍以边缘热带成分为主，并有相对丰富的亚热带－温带科如木兰科、山茶科、山茱萸科、山矾科、忍冬科、冬青科等以及一些东亚和喜马拉雅特徵科，如岩梅科、十齿花科、领春木科、茶藨子科和鞘柄木科，显示了它与东亚温带植物区系也有较多联系。

Objectives To search for mutations in NOTCH3 gene in four Chinese families with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy.

方法对 4个经临床和病理检查证实的CADASIL家系中的先证者作NOTCH3基因编码区外显子 1～ 12的聚合酶链反应和DNA测序，对家系 2和 4中的部分亲属也作了同样的检查。

The result shows that oil and gas from Xujiahe group mainly comes from autogenic coal source rock,and bind is main.Genetics of natural gas is mainly mature humic mothermaterial,small condensate oil and crude oil is m... \r\n

指出须家河组油气主要来自须家河组自身的煤系烃源岩，并以煤系泥岩贡献为主；天然气以成熟腐殖型母质成因为主，少量的凝析油和原油来自其中的混合型有机质，不具备典型煤成油特征。

Two RAPD molecular markers located on different arms of 2Ai-2 chromosome from Thinopyrum intermedium were selected and the generations of the hybrid generation derived from Zhong 4 Awnless and wheat were analyzed. Two chromosome translocation lines were screened for wheat breeding program to control BYDV.

本研究采用RAPD方法，对具2Ai-2端体和完整染色体异附加或异代换系进行分析，从随机引物中，选出两个分别位于2Ai-2染色体两臂上的分子标记，然后用这两个标记对中间偃麦草和普通小麦的杂交后代进行筛选，选出小麦抗黄矮病易位系新材料。

Thinopyrum intermedium,one of the relative species of common wheat,is a kind of dominant wheat germplasm resource for the resistance to stripe rust in wheat genetic improvement. With using Chinese spring phlb as recurrent parents and awnless Zhong 4(a partial chromosome of Thinopyrum intermedium)as donor parents,that is backcross selection,the offspring BC_2F_(7～9)were acquired.Cytology check and genome in situ hybridization, were used for the translocation lines and substitution lines detection.

本研究采用常规杂交并辅抗性鉴定等方法，以中国春phlb突变体为轮回亲本，利用无芒中4，转育中间偃麦草的抗条锈性，并通过细胞学和DNA原位杂交检测，鉴定和筛选普通小麦—中间偃麦草的抗条锈病异代换系或易位系。
