The diverse types of tracheary elements and perforation plates in secondary xylem of A. asiatica show that previous knowledge about the tracheary elements and perforation plates in secondary xylem of A. asiatica is not complete and thus any inferences about the aboriginality and evolution of a taxon made depending on these traits are not reliable.

根据类叶升麻次生木质部中多变的管状分子类型，认为以往积累的有关毛茛科植物管状分子类型及导管穿孔板类型是不全面的，因此以该性状为参考作出的有关某一个类群的原始性和进化性的推论也是不可靠的。

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。

objective to investigate the clinical characteristics and the surgical treatment for perforation of gastric cancer.methods we summarized 22 cases suffering from perforation of gastric cancer in our hospital,6 were treated with repair of perforatlon and gastrojejunostomy at the same time,8 with partial gastrectomy,8 wth radical gastrectomy for gastric cancer（d2,d3）,and positive treatment such.as intraperitoneal chemothrapy to the patients above.results the life expectancy of patients treated with repair of perforation,partial gastrectomy or radical gastrectomy for gastric cancer was 6,29.2 and 37.3months.conclusion reasonably select surgery methoty and positive treatment are keys to prolong the survival time.

目的 探讨胃癌穿孔的临床特点及外科治疗方法。方法对22例胃癌穿孔病人实施不同手术方式治疗。其中行穿孔修补加胃肠吻合术6例，姑息性胃癌切除术8例，胃癌根治术（d2，d3）8例，后两者术后均行腹腔化疗等综合治疗。结果穿孔修补加胃肠吻合术、姑息性胃癌切除术、胃癌根治术术后平均生存期分别为6个月、29.2个月、37.3个月。结论合理选择术式，综合治疗，是延长病人生存期的关键。

objective to discuss treatment of acute perforation of peptic ulcer,to elevate i stage operation recovery rate.methods 208 cases in 20 years were retrospectively analysed,86 cases (41.35%) were recovered by subtotal gastrectomy;18 cases (20.93%) were undergone billroth i anastomosis;68 cases (79.07%) billroth ⅱ;42 cases (61.76%) billroth ⅱ precolonic anastomosis;26 cases (38.24%) retrocolic anastomosis.results in 86 cases,1 case was complicated by gastroparesis,others all recovered.all cases were followed up for 5 years.conclusion the procedure can shorten the recovery time and increase quality of life.

目的 探讨消化性溃疡急性穿孔的治疗方法，旨在提高ⅰ期手术治愈的成功率。方法回顾性总结分析20年间手术治疗消化性溃疡急性穿孔208例，其中86例（41.35%）采用胃大部连同病灶切除ⅰ期治愈，胃肠重建采用billrothⅰ式吻合18例（20.93%），billrothⅱ式吻合68例（79.07%），billrothⅱ式结肠前吻合42例（61.76%），结肠后吻合26例（38.24%）。结果 86例中除1例billrothⅱ式吻合术后发生胃瘫并发症，经保守治疗月余治愈外，其余病例术后恢复顺利，均随访5年以上情况良好。结论消化性溃疡急性穿孔的ⅰ期手术治疗，解决了因溃疡穿孔单行修补术后再次复发穿孔、出血、幽门梗阻、粘连、溃疡恶变而重复手术等问题，缩短了治愈周期，提高了生存质量。
