复发性脑胶质瘤及其放射治疗

1976～1986年肿瘤科收治脑胶质瘤42例,10例复发,其中6例采用单纯放疗,用~60钴γ线。5例脑胶质瘤予肿瘤区局部照射,DT44～57Gy/6-7周,1例髓母细胞瘤予全脑、肿瘤区及全脊髓照射、脑中平面量DT38Gy/5周;肿瘤区51Gy/7周;脊髓18Gy/8周。结果:有效1例,显效2例,无效3例。本研究提示对于已不能釆用其他手段治疗的复发病人,放疗仍有一定效果。     

Approaches for end-of-life care in the field of gynecologic oncology: an exploratory study

We sought to explore the Society of Gynecologic Oncologists (SGO) members' opinions and decisions about end-of-life issues and incurable conditions. A survey was mailed to members of the SGO. Their responses were recorded on a Likert scale and entered into a database. The survey explored opinions, experiences, and decisions in managing terminally ill gynecologic oncology patients. Of 900 surveys, 327 were returned (response rate, 36%). Seventy-three percent were men, 89% were white, and 72% were of Christian denomination. Respondents believed that 97% of patients who are dying realize that they are dying but stated only 40% of these patients initiate conversations about end-of-life issues. In contrast, 92% of respondents stated that they initiate end-of-life discussions with patients. Ninety-two percent of respondents thought that the patients should be allowed to make end-of-life choices independently after the facts are given to them. However, 44% thought that it is important to influence the way information is presented, and 54% believe that the gynecologic oncologist (GO) controls the outcome of end-of-life discussions. Although the physicians' sex, race, religion, and age did not correlate with their treatment decisions, religion did correlate with less fear of death (P = 0.011) and less discomfort when talking with patients about death (P = 0.005). Fifty-four percent of respondents believed that the GO controls the outcome of end-of-life discussions, and 40% believe that their actions prolong the process of dying. Expanding our understanding of what motivates GOs to recommend continued treatment over palliation is important for preserving informed patient-motivated end-of-life decisions.     

急诊左半结肠一期切除吻合术25例治疗体会

目的探讨急诊左半结肠切除一期肠吻合的可行性。方法腹腔探查完后，用布带结扎横结肠，游离肠系膜后，于预切除肠段的上端切开作肠外减压，挤压排空粪便，切除病变肠管，端端吻合，术后作肛管扩张，停留肛管引流，胃肠减压。结果全部病人预期痊愈出院，无发生吻合口漏和腹腔污染。结论该法有利于吻合口的愈合，增加左半结肠一期切除吻合的安全性，减少第2次手术痛苦，可推荐为左半结肠急诊切除一期吻合的良好方法。     

肿瘤微血管密度与肝癌病理及预后关系

目的 探讨肿瘤微血管密度（MVD）与肝细胞性肝癌临床病理及预后的关系。方法对30例肝细胞性肝癌根治性切除病理组织切片进行苏木精伊红染色．并用CD34单克隆抗体进行免疫组化染色，计数被CD34抗体染色的肿瘤血管内皮细胞数，以测定MVD。对MVD与临床病理因素及术后生存率关系进行分析。结果 单因素分析结果表明．MVD水平与肿瘤大小、TNM分期都是影响肝细胞性肝癌预后的因素；多因素分析结果表明．肝癌大小及肿瘤分期是肝细胞性肝癌独立预后因素。结论 MVD是肝细胞性肝癌一种预后因素。     

CT增强扫描在评价NSCLC血管生成中的临床意义

目的　探讨非小细胞肺癌 (NSCLC)血管内皮生长因子 (VEGF)的表达水平与CT增强程度的关系 ,从影像学角度评价肿瘤血管生成在肺癌诊断、治疗及淋巴结转移中的临床价值。方法　对 30例NSCLC病人进行动态螺旋CT扫描 (SCT) ,测量病灶增强幅度 ,并利用免疫组化技术检测VEGF。对病灶增强值、VEGF阳性表达及淋巴结转移情况进行统计学分析。结果　 30例肺癌病人CT增强值均数为 (36 .2 8± 6 .41 )HU ,VEGF阳性表达 2 1例 ,阴性表达 9例。VEGF在中晚期的阳性表达高于早期病人 (Ρ<0 .0 5) ,淋巴结转移组高于非淋巴结转移组 (Ρ <0 .0 5) ;癌灶增强值与VEGF阳性表达、肿瘤分期及淋巴结转移亦呈正相关。结论　NSCLC的CT增强程度能够反映肿瘤的血管生成 ,并与淋巴结转移密切相关 ,有助于肺癌的诊断、TNM分期 ,而且可以从肿瘤分子生物学行为方面补充目前肺癌分期方法的不足     

应用吻合器行中、下段直肠癌切除术后吻合口漏──附10例报告

我科自１９８１年３月至１９９１年１２月应用吻合器行中、下段直肠癌切除术６７例，同期发生吻合口漏１０例（１４９％）。本文分析了吻合口漏发生的因素。病变部位、病灶范围、术中操作技术、术前肠道灌洗以及术后骶前引流是影响吻合口漏的重要因素。本文总结了吻合口漏的治疗方法，提倡保守治疗，或加作暂时性横结肠造口术。     

Morphometric study of nucleolar organizer regions in human oral normal mucosa, papilloma and squamous cell carcinoma

A morphometric study of nucleolar organizer regions (NOR) was performed to analyze their distribution, volume, number and shape in the different strata of human normal oral mucosa epithelium and papilloma and in squamous cell carcinoma employing microphotographs of silver-stained paraffin sections. The different NOR-related parameters evidenced significant differences between normal mucosa, papilloma and squamous cell carcinoma. The functional polarity of normal mucosa epithelium and of papilloma is also evidenced in terms of NOR-related parameters. The discriminative value of certain NOR parameters was demonstrated.     

Single-stage repair of severe hypospadias using bladder mucosa graft

Our experience of single-stage repair of severe hypospadias (penoscrotal, scrotal, and perineal) in 30 children using urinary bladder mucosa for urethroplasty is reported. These children had severe chordee, small prepuce, and often ventral transposition of the penis with bifid scrotum where Devine and Horton, Asopa, or Duckett techniques are not so suitable. The graft uptake was uniformly satisfactory. Ten patients had complications; most of the fistulae healed spontaneously. Surgical intervention was required in 2 cases only: 1 for a fistula and another for a stricture with fistula. Meatal stenosis, seen in 4 cases, led to delayed distal fistulae in 2, which healed spontaneously with meatal dilatation. Regular dilatation of the external meatus is recommended to prevent this problem.
