60例急性病毒性脑炎的临床分析

目的　评价急性病毒性脑炎的诊断与治疗。方法　收集 1993～ 2 0 0 1年 6月的住院病案 60份 ,就临床症状、神经体征、周围血白细胞计数和分类、脑脊液、脑电图、脑CT检查 ,以及单用激素组和激素 +抗病毒毒药组之间的疗效关系进行分析。结果　本组病毒性脑炎可分为六种临床类型 :精神异常 ;持续性剧烈头痛伴呕吐 ;强直 -阵挛性抽搐 ;持续性意识障碍 ;脑神经损害、失语、偏瘫 ;小脑性共济失调。前三型最为常见 ,并且三型之间的临床现象有相互穿插出现的现象。经统计学处理 ,单用激素组与激素 +抗病药物组之间的疗效无显著性差异。结论　急性病毒性脑炎为一种自限性疾病 ,但在没有病毒学检查的情况下 ,尚应和急性播散性脑脊髓炎或多发性硬化作鉴别     

Time-frequency analysis of heart murmurs. Part II: Optimisation of time-frequency representations and performance evaluation

The basic parameters of the spectrogram, the Choi-Williams, and the Bessel distributions are adjusted to provide the best time-frequency representations (TFRs) of the simulated murmur signals of mitral stenosis, mitral regurgitation, aortic stenosis, aortic regurgitation, and of two musical murmurs. The initial adjustment of the parameters of each TFR technique is performed by computing and minimising the relative averaged absolute error between the frequency contours at −3dB and −10dB of each TFR of the simulated murmurs and those of the theoretical distribution of the same signals. The results show that the spectrogram generally provides very good to excellent performance in representing the TFRs of stenotic and regurgitant murmurs. Improvements provided by the Choi-Williams and the Bessel distributions are minor but not systematic for the two signal-to-noise ratios tested (0 and 30 dB) and for the two frequency contours estimated. The Bessel and the Choi-Williams distributions provide the best performance for the musical murmurs. The study shows that although a single technique cannot be optimal for all six murmurs, the spectrogram using a Hamming window of 30 ms is an acceptable compromise to detect the six simutated heart murmurs.

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.     

采用一式三份数码对号入座法管理病案号

采用"对号入座法"管理病案号,先把姓名索引卡、病案封面、病案号索引簿预先印上号码.待病人入院,取出相应一式三份号码,做好各种索引.结果,派出的病案号被取出,乘下空白的是未使用.如果旧病友再次入院;就要在病案的姓名索引中或电脑中查找旧号,这样有效地控制重号、漏号.     

隆突性皮纤维肉瘤23例临床分析

本文报告了我科1978～1990年间收治的降突性皮纤维肉瘤23例,均经组织学证实.治疗以手术切除为主,术后局部复发率为65.2%.无一例发生转移.切除不彻底是复发的主要原因.作者指出广泛切除是防止复发的主要措施,手术前后的放疗有可能减少复发.     

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。
