The anatomical study deepens the knowledge of G-type conducting cells: 1 It proves the theory of two depositional process for secondary wall (Bierhorst, 1960): the discontinuous cellulose layer is laid down before the continuous lignified layer; the former layer is prone to be broken down, while the latter is highly decay-resistant; 2 It suggests that the cellulose primary and secondary walls of tracheids are not perforated. Instead of longitudinal pits (Li, 1992), the lignified tracheid secondary wall of Hsüa possesses irregular simple perforations; 3 In Hsüa reflexa and Huia gracilis, the perforation casts may represent the thickness of lignified secondary wall; 4 The wall structure of G-type tracheid is diversified. At the genus level, the secondary wall structure differs in the distribution, internal shape and structure of the perforations; 5 Perforations of some G-type tracheids combine the characters of S-type tracheids in their distribution, density and diameter.

解剖学的研究加深了对G-型输水管胞的认识 1）验证了管胞次生壁分两个阶段形成的理论（Bierhorst，1960），即先后形成不连续的纤维质层和连续的木质化层，前者易被分解，后者抗侵蚀性强；2）证明管胞纤维质的初生壁和次生壁不具穿孔，Hsüa管胞的木质化次生壁具有不规则的简单穿孔，而不是纵列的纹孔（Li，1992）；3）Hsüa reflexa和Huia gracilis的穿孔铸体可代表木质化次生壁的厚度；4）G-型管胞壁层结构具多样性，植物属一级的分异主要表现在次生壁穿孔的分布、孔腔形状和结构的不同；5）某些G-型管胞的穿孔在其分布、密度和孔径方面可兼有S-型管胞的特征。

Under the scanning electron microscope , for the first time we compare and study both the coalified tracheids through chemical maceration and permineralized tracheid lumen casts. This method reveals the microstructures of wall and perforations of G-type tracheids: 1 The lignified layer of secondary wall is composed of uneven material and further divided into S〓, S〓, S〓 layers; with the smooth enclosing wall, the perforation is internally dumbbell-shaped; 2 In Huia gracilis, the enclosing wall of tracheidal perforation contracts and possesses secondary perforations. The perforation has thickened border facing the tracheid lumen.

本文首次在扫描电子显微镜下对比研究经化学浸解获得的碳质管胞和矿化的管胞腔铸体，明确揭示出了G-型管胞壁层和穿孔的显微结构：1）Hsüa reflexa次生壁木质化层的组成不均一，分为S〓、S〓和S〓层；穿孔腔为哑铃形，腔壁光滑；2）Huia gracilis的穿孔腔收缩，腔壁上发育次级穿孔，孔口具有边缘加厚。

According to the size and position of perforations of the ear drum, we can select endotoscope or operating microscope and different materials for myringoplasty. For central type of perforations, the application of endotoscope with fat plug or perichondrium is reliable and minimally invasive.

针对不同鼓膜穿孔的特点有选择性地应用手术显微镜或耳内镜技术，以及不同来源的移植材料进行鼓膜成形术，均能达到有效的治疗结果；对中央型的穿孔应用耳内镜下脂肪、软骨膜材料能达到微创目的。

Methods 109 patients(109 ears) with perforations of the ear drum were recruited from November 2007 to March 2009 . The patients were divided into 3 groups according to the size and position of perforations of the ear drum: 31 accepted myringoplasties with a fat plug , 43 accepted perichondrium via endotoscope, and 35 accepted fascia musculares via an operating microscope.

针对不同大小及位置的鼓膜穿孔患者109例109耳，选择性地采用耳内镜下脂肪组织鼓膜成形术(31耳)、软骨膜鼓膜成形术(43耳)和显微镜颞肌筋膜鼓膜成形术(35耳)，比较三组患者的治疗效果。

The authors used a database of Medicare beneficiaries aged 65 years and older to identify individuals who were cancer-free and who had undergone at least one colonoscopy or sigmoidoscopy between 1991 and 1998, and they then calculated the incidence and risk of perforation within seven days of the procedure.During 39,286 colonoscopies, there were 77 perforations, or 1.96 perforations per 1,000 procedures, compared with 31 perforations during 35,298 sigmoidoscopies, or 0.88 perforations per 1,000 procedures.

结果显示，在39，286位做大肠镜筛检的民众之中，有77位发生肠穿孔。35，298 位做直肠镜筛检的民众，有31位发生肠穿孔，也就是说，做大肠镜筛检者，每1，000位就有1.96位可能发生肠穿孔，而直肠镜筛检的肠穿孔发生率则为每1，000位中有0.88位。

Deep research and comparison show that, besides the centrarch xylem, H. reflexa has G-type tracheids. Upon and between the annular secondary thickenings, the lignified layer of secondary cell wall bears irregular simple perforations of small diameter and high density. So these perforations have the characters of S-type tracheids. The robust xylem strand and dense perforations indicate the strengthened water-conducting capacity.

深入的研究和比较表明H.reflexa的木质部除为心始式外，管胞为G-型，次生壁的木质化层具有不规则的简单穿孔，穿孔直径小，密度大，分布在环纹次生加厚带和其间，兼有S-型管胞穿孔的特征；粗壮的木质部束和密集的穿孔表明较强的输导能力。
