Microsurgical medialis pedis flaps for reconstruction of soft-tissue defects in the hand.

The medialis pedis flap (MPF) has been used for the reconstruction of soft-tissue defects in the hand since 1990. From January 1997 through January 2000, 19 patients (15 male, 4 female) with hand injuries underwent microsurgical MDF reconstruction at Chang Gung Memorial Hospital. There were finger injuries in 16 patients and palm defects in 3 patients. The mean patient age was 32.6 years (age range, 16-58 years). Flap size ranged from 4.5 x 2 cm to 7 x 6 cm (mean, 6 x 2.8 cm). Only one flap had partial loss. The donor site was closed primarily in 9 patients, and was closed using a split-thickness skin graft in 9 patients and a full-thickness skin graft in 1 patient. At a mean follow-up of 13 months, the protective sensation was 16 mm using the static two-point discrimination test and was 10 mm using the moving two-point discrimination test. Based on this retrospective study the authors conclude that (1) the MPF has the advantages of thin and glabrous skin, (2) the size of pedicle is compatible with the recipient vessel in the hand, (3) there is low donor site morbidity, and (4) achieving protective sensation is possible.     

Medialization thyroplasty for cancer-related unilateral vocal fold paralysis.

OBJECTIVE: To justify the application of medialization thyroplasty in Chinese patients with symptomatic cancer-related unilateral vocal fold paralysis (UVFP). STUDY DESIGN AND SETTING: Retrospective chart review from February 2000 to March 2006. RESULTS: Eighty-seven Chinese patients undergoing medialization thyroplasty for UVFP were included; there were no significant differences between the cancer-related and benign groups in terms of the speech and swallowing rehabilitation outcome and the perioperative complication rate (P > 0.05). The median survival time of cancer-related UVFP patients from the date of medialization to death was 129 days. Age more than 65 years was identified as the only factor for a shorter survival period after medialization (P = 0.040). CONCLUSION: Medialization thyroplasty restores satisfactory speech and swallowing and has a low perioperative complication rate in Chinese patients with cancer-related UVFP. Postmedialization survival period was also reasonable. SIGNIFICANCE: Medialization thyroplasty is a justifiable treatment option for cancer-related UVFP.     

肛管鳞癌的诊断与治疗(附15例分析)

目的探讨肛管癌诊断、治疗和预后的相关因素。方法北京医院1984-1998年间收治15例肛管鳞癌,首次诊断为肛管癌者仅5例。15例中行放疗化疗11例,8例行Miles手术。结果病理均证实为鳞癌。根据NCCN(2003年)分期,Ⅰ期6例,Ⅱ期4例,ⅢA期2例,ⅢB期3例。免疫组织化学染色显示肿瘤组织间质纤维化(+++)者4例,(++)者7例,(+)者4例。随诊最长10年,平均生存期(47±27.6)个月。结论肛门指诊是发现和诊断肛管癌的重要手段。放疗以及以放疗为主,化疗、手术为辅的综合治疗是肛管癌的主要治疗方法。肿瘤分期、腹股沟淋巴结转移、治疗方法以及肿瘤组织间质纤维化对病人的预后均有影响。     

新生鼠和成年鼠脑7种微量元素含量的比较

利用高频电感耦合等离子体原子发射光谱法（ICP－AES）测定Sprunge－Dawley大鼠新生期大脑皮层、海马、小脑、间脑和脑桥等部位的锌、铁、铜、锰、铬、锶、钼等7种微量元素的含量，并与成年动物做了比较。结果表明：（1）新生期大鼠全脑7种微量元素含量的多寡依次为：锌、铁、铬、锶、锰、铜、钼；成年期时钢跃居第四位，总含量低于新生期。（2）脑内不同部位微量元素的含量不同。新生大鼠海马和小脑内多数元素含量高于其他脑区，钼在间脑和海马中含量较高。成年鼠皮层、海马微量元素含量较高，皮层内铜、锶、钼含量最低。     

视盘血管炎——关于混合型的研讨

对６０例（６３眼）视盘血管炎的临床分型进行了探讨，结果表明，除分为Ⅰ、Ⅱ两型外，尚存在混合型，当视盘睫状血管炎性病变波及中央静脉，或两个血管系统同时受炎症侵犯时，即可再现混合型的临床表现，视盘明显水肿，视网膜静脉迂张，散在渗出，出血，动脉狭细。眼底荧光血管造影可见视盘荧光早期充盈明显迟缓，后期渗漏面积〉２．０ＰＤ，视网膜循环时间延长，混合型兼有Ⅰ，Ⅱ两型的临床特征，应作为一个独立类型存在，同时观察     

Ultraviolet Laser-Induced Fluorescence Spectroscopy Diagnosis of Human Stomach Malignant Tissues

To evaluate the potential of laser-induced autofluorescence spectroscopy for the detection of premalignant lesions of human stomach, fluorescence properties of stomach tissues have been investigated in vitro and in vivo. A specially made optical fibre probe and the multichannel fluorescence collection system have been used successfully in our research.

“C”型曲线的中耳声学特性改变与鼓室积液的关系

对40耳声导抗检查为“C”型曲线患耳进行中耳系统共振频率点测试并进行鼓室穿刺抽液,结果表明:共振频率点低于600Hz,患耳鼓室积液阳性率为82.1%,高于600Hz患者鼓室和液阳性率16.7%,提示依据鼓室导抗图和共振频率点测定可初步判断“C”型曲线患耳鼓室积液的可能.

肺肿瘤细胞雌激素、孕激素和凝集素受体的组化研究

用酶联亲合组化法对46例肺肿瘤细胞进行了雌激素受体(ER)和孕激素受体(PR)检测。同时测定14例肺瘤肿患者血清雌二醇(E_2)浓度。结果表明:肺肿瘤 ER 阳性率为36.9%,PR 阳性率为13.0%。阳性率与性别、病理类型及血浆 E_2浓度无关。认为肺癌的发生发展可能与雌激素有依赖关系,提示内分泌疗法可能会成为原发肺肿瘤的一种治疗手段。另用 ABC 法对上述46例肺肿瘤中的29例进行了花生凝集素受体(PNA-R)和麦胚凝集素受体(WGA-R)的检测,PNA-R 在腺癌大都为顶浆型分布,鳞癌和透明细胞癌则多为胞膜型分布。结果提示 PNA-R 是肺癌分化过程中的一种标志,对肺癌分型、预后判断有一定协助作用。同时将29例肺肿瘤 PNA-R 与 ER 状况作对比研究,探讨了二者之间的相关性及可能的发生机制。
