探讨低强度Ｈｅ－Ｎｅ激光血管内照射对脑动脉硬化症的治疗作用。方法对３５例脑动脉硬化症患者给予每日１次ＩＬＩＬＩ治疗及３３例对照组给予维脑路通治疗，观察两组治疗前后及级组间血液流变学指标的变化。结果ＩＬＩＬＩ治疗后血流流变学指标测值显著低于对照组。临床症状总有效率为９４％。结论ＩＬＩＬＩ对脑动脉硬化症有较好的治疗作用。     

应用OKT单克隆抗体检测单纯疱疹性角膜炎中药治疗前后外周血T细胞亚群

为探讨单纯疱疹性角膜炎中药治疗前后外周血T细胞亚群变化，用OKT单克隆抗体检测了112例单纯疱疹性角膜炎，随机分为中药治疗组60例，西药对照组52例。发现中药治疗组治愈率86．6％，总有效率98．33％；西药对照组治愈率71．15％，总有效率90．38％；两组差异有显著性（P＜0．05）。外周血T细胞亚群：治疗前，两组患者辅助性T细胞（TH）的比例明显低于抑制性T细胞（TS）（P＜0.01）；中药治疗组辅助性T细胞（TH）治疗后较治疗前明显提高（P＜0．05），而西药对照组治疗后辅助性T细胞（TH）较治疗前虽有提高，但差异无显著意义（P＞0．1）。说明单纯疱疹性角膜炎患者服中药后，机体内辅助性T细胞比值增加，细胞免疫功能增强。

~（131）I治疗Graves’病的突眼症状的疗效分析

对４８０例经１３１Ⅰ治疗的甲亢患者的疗效与是否伴突眼以及突眼症状是否有改善等系列问题进行了分析研究。结果表明：４８０例甲亢患者中２３３例伴突眼，其发病率为４９％，２３３例突眼患者中，９０例突眼恢复（３９％），好转９６例（４１％）．未变化４５例（１９％），加重２例（０．８５％），总有效率８０％。认为甲亢的治疗效果与有无伴发突眼关系不密切，１３１Ⅰ治疗甲亢伴突眼者可使大部分突眼症状得到明显改善。据此，我们认为在甲亢伴突眼的治疗中１３１Ⅰ应视为一种有效和较好的治疗方法。

Vacuum-compression therapy for ischemic disease of the extremities：experience with 40 patients

Objective To study the clinical effects of vacuum-compression therapy for ischemic disease of the extremities. Methods A total of 40 cases of peripheral arterial disorders, including 23 thromboangiitis obliterans (31 limbs) and 17 arteriosclerosis obliterans (23 limit), were treated by a self-made vacuum-compression therapeutic apparatus. Results The effective rate in thromboangiltis obliterans and arteriosclerosis obliterans groups was 96.77% and 92.23%, respectively. The cuffs on the apparatus were improved to eliminate discomfort in the patients during treatment. "Rebound symptom" was observed during treatment, which had not been reported previously. Conclusion Vacuum-compression therapy has a good prospect for treating ischemia of the extremities.     

急性白血病并发自发性脾破裂的早期诊断及治疗

急性白血病并发自发性脾破裂较为罕见,且预后不良。本文通过临床所见3例,结合有关文献,就其早期诊断、发病机理及治疗进行讨论。认为B型超声波检查对于自发性脾破裂是一种既方便又准确的方法。脾切除是挽救病人生命的一个好办法。     

NM_(23)蛋白产物在膀胱癌组织中的表达

应用免疫组化SABC法研究了NM23／NDPK在正常膀胱、膀胱癌及癌旁组织中的表达。结果显示：NM23在正常膀胱中表达阴性，而癌和癌旁组织中的阳性表达率分别为83．3％和87．5％。鳞癌、腺癌的NM23表达与诸临床病理因素无关，而移行细胞癌NM23表达强度与肿瘤病理分级和临床分期正相关。有淋巴结或远处转移肿瘤的NM23阳性表达率较未转移者低，阳性表达组术后3、5年生存率明显高于阴性组。提示NM23可能参与了膀胱癌的发生，并对移行细胞癌的浸润、转移和预后起负调控作用。     

Ablation of Barrett's esophagus using the second-generation argon plasma coagulation

Objective To investigate the efficacy and safety of the second-generation argon plasma coagulation (VIO APC) in ablation of Barrett's esophagus. Methods Eighteen patients with Barrett's esophagus (12 males, median age of 55 years, median length of 2.1 cm,1 low-grade dysplasia, 13 cases of short segment Barrett's esophagus) received VIO APC, which was performed at a power setting of 40W and argon gas flow at 1. 5-2. 0 L/min, "forced" mode, in 1-3 sessions (mean 1.3). All the patients received treatment with high-dose proton pump inhibitors. The main complaints before ablation were upper abdominal pain in 12 patients (66%), sour regurgitation in 14 patients (77%), and dysphagia or odynophagia in 7 patients (38%). Two patients (11%) had esophageal hiatal hernia. Results The percentage of patients in whom ablation was endoscopically achieved proximal to the gastroesophageal junction was 77. 8%(14/18), and histologically achieved in 66. 7% (12/18). Berried glands were observed in 2 patients who had achieved endoscopic ablation, the areas of Barrett's mucosa were reduced by more than 60% in the other 4 patients. After treatment, 4 patients had transient retrosternal pain and 3 patients had mild epigastric discomfort. One patient had small amounts of hemorrhage during the process, and it ceased after norepinephrine and thrombosin were administered through endoscope biopsy channel. No esophageal stricture or other severe adverse events was observed. During 11.8 (4-15) months' follow-up, the patients who had achieved the complete ablation had no evidence of relapse of Barrett's esophagus. Conclusion VIO APC with a relatively low power setting can effectively ablate the Barrett's mucosa with special intestinal metaplasia when standard APC has been done. No severe adverse events were observed. Long-term follow-up is needed to assess cancer prevention and the durability of the neo-squamous epithelium.

本文报告了我院1957～1984年共收治的肾脏恶性肿瘤216例其中肾细胞癌120例(55.6%),占肾脏肿瘤的第一位。有82例通过手术及活组织检查得到病理结果,透明细胞癌76例(占91.5%),颗粒细胞癌2例,未分化癌5例。在患者中31岁以上者占86.7%,而20岁以下者6例,其中年龄最小者为7岁(1例),值得注意。本组中75例做了肾切除术。术后随访,三年存活率为47.1%,五年存活率为32.9%,有23例存活五年以上。其中Ⅰ期17例,Ⅱ期6例。因此在今后应尽早诊断、治疗肾肿瘤,以提高长期存活率。     

INTELLIGENT TOOLS FOR PREDICTING ANXIETY OF ALZHEIMER'S PATIENTS

Objective To predict the incidence of anxiety in Alzheimer's disease (AD) patients by using machine-learning models. Methods A large randomized controlled clinical trial was analyzed in this study, which involved AD patients and caregivers from 6 different sites in the United States. The incidence of anxiety in AD patients was predicted by backpropagation artificial neural networks and several machine learning models, including Bayesian Networks, logistic regression, ADTree, J48, and Decision table. Results Among all models for predicting the incidence of anxiety in AD patients, the artificial neural network with respectively 6 and 3 neurons in the first and second hidden layers achieved the highest predictive accuracy of 85.56 %. The decision tree revealed three main risk factors: "caregiver experiencing psychological distress", "caregiver suffering from chronic disease or cancer", and "lack of professional care service". Conclusion The unique ability of artificial neural networks on classifying nonlinearly separable problems may substantially benefit the prediction, prevention and early intervention of anxiety in Alzheimer's patients. Decision tree has the double efficacy of predicting the incidence and discovering the risk factors of anxiety in Alzheimer's patients. More resources should be provided to caregivers to improve their mental and physical health, and more professional care services should be adopted by Alzheimer's families.     

HBeAg特异免疫复合物检测及临床意义

采用单克隆抗－ＨＢｅ固相ＥＬＩＳＡ法检测１１８例ＨＢＶ感染者血清中ＨＢｅＡｇ特异免疫复合物（ＨＢｅＡｇ／ＩＣ），结果表明∶ＨＢｅＡｇ／ＩＣ与ＨＢＶ复制相关，可作为ＨＢＶ复制的一种血清学标志，ＨＢｅＡｇ阴性、ＨＢＶＤＮＡ阳性者中，６２．２％患者ＨＢｅＡｇ／ＩＣ阳性，提示ＨＢｅＡｇ／ＩＣ的形成致使夹心法不能检出ＨＢｅＡｇ，这类患者仍可以是ＨＢＶ野毒株感染，并非均为ＨＢｅＡｇ缺陷变异株感染；ＨＢｅＡｇ／ＩＣ阳性血清ＡＬＴ异常率明显高于ＨＢｅＡｇ／ＩＣ阴性血清（Ｐ＜０．０１），提示ＨＢｅＡｇ／ＩＣ存在与肝损伤有关。

本文报道我科于1985年5月～1987年7月应用5-氟脲嘧啶120h 持续静脉滴注加顺铂治疗21例晚期食管癌的近期结果。在可评价疗效的19例中完全缓解1例(5.5%),部分缓解8例(42.1%),稳定4例(22.2%)进展6例(31.5%),有效率47.6%。本文对影响疗效的诸因素和毒性反应作了分析,认为此方案可作为晚期食管癌的姑息疗法或为综合治疗中的一部分。     

颞肌外感受性抑制试验对慢性头痛的鉴别价值

按Ｓｃｈｏｎｅｎ方法使用肌电图对５５例已排除神经系统器质性疾病的慢性头痛病人及１２例正常人进行３种不同频率的电刺激，观察颞肌最大收缩干扰相于电刺激的潜伏期后出现的两个静息期ＥＳ１和ＥＳ２，显示２Ｈｚ刺激条件下肌收缩性头痛组ＥＳ２明显短于对照组（Ｐ＜０．００１）和偏头痛组（Ｐ＜０．０１）。本文认为此试验对肌收缩性头痛和偏头痛的鉴别有一定价值。
