小儿急性淋巴细胞白血病的染色体观察

对９例急性淋巴细胞白血病患儿诊断时染色体的分析，染色体数目异常检出率为６／９，观察核型与临床的关系，发现染色体数目异常可视为预后差的标志。认为染色体分析对小儿ＡＬＬ的疗效监测及预后评估的价值，可作为ＡＬＬ的常规检查项目。     

增殖细胞核抗原(PCNA)与胃癌预后关系的免疫组化研究

应用ＳＬＡＢ免疫酶标法在石蜡切片上半定量分析增殖细胞核抗原（ＰＣＮＡ）的表达与７３例胃癌患者预后的关系，探讨其临床应用价值。结果表明，以ＰＣＮＡ阳性细胞５０％为界线，阳性率＞５０％者术后生存期较短，５年生存率较低，而淋巴结转移率则较高。提示ＰＣＮＡ检测可作为胃癌预后判断的良好指征。     

骨肉瘤增殖细胞核抗原（PCNA）表达及其与临床病理和预后的关系

应用单克隆抗体ＰＣ１０免疫组方法半定量分析了增殖细胞核抗原表达与５０例骨肉瘤患者预后的关系。ＰＣＮＡ阳性级者预后差，其中半定量分级与骨肉瘤术后生存期呈显著负相关。ＰＣＮＡ表达与骨肉瘤组织学分级及骨样组织分化程度相关。     

Treatment and prognostic factors in patients with hepatocellular carcinoma.

INTRODUCTION: Hepatocellular carcinoma is a leading cause of death from cancer worldwide. Survival of patients depends on tumor extension and liver function, but yet there is no consensual prognostic model. AIMS: To evaluate the influence on survival of pretreatment parameters (clinico-laboratorial, liver function, tumor extension, Okuda and Cancer of the Liver Italian program (CLIP) staging) and treatment modalities. METHODS: We retrospectively analyzed 207 patients, diagnosed between 1993 and 2003. The initial treatment was: surgery--six patients; radiofrequency ablation--21; percutaneous ethanol injection--29; transarterial chemoembolization--49; tamoxifen--49; supportive care alone--53. Factors determining survival were assessed by Kaplan-Meier method and Cox regression models. RESULTS: Median survival was 24 months. In univariate analysis, Child-Pugh classification and Model for end-stage liver disease (MELD) score, portal vein thrombosis (PVT), tumor size, number of lesions, Okuda and CLIP scores were all associated with prognosis (P < 0.001). Alpha-fetoprotein levels were not predictive of survival. Independent predictors of survival were ascites, bilirubin, PVT and therapeutic modalities (P < 0.001). In early stage hepatocellular carcinoma (HCC), survival was similar for both percutaneous ablation modalities, either radiofrequency or ethanol injection (P = NS). In advanced HCC, survival was better in patients receiving tamoxifen than supportive care alone (P < 0.001). CONCLUSION: This study reinforces the importance of baseline liver function (Child-Pugh classification and MELD score) in the survival of patients with HCC, although staging systems allowed the stratification of patients in different prognostic groups. Ascites, bilirubin and PVT were independent pretreatment predictors of survival. All treatments influenced the patient's outcome, whether in early or advanced stages.     

应用联合减压术治疗中晚期脑疝疗效观察

目的　观察联合减压术治疗特重型颅脑损伤合并嵌顿性脑疝的效果。方法　将 97例格拉斯哥昏迷评分 (GCS) 3～ 5分的特重型颅脑损伤合并嵌顿性脑疝患者随机分为两组 ,分别采用联合减压术 (46例 )与常规骨瓣开颅术 (5 1例 )治疗 ,术后两组均经常规治疗。随访 1～ 32个月 ,平均 7个月。比较两组患者临床疗效、颅内压变化及并发症发生率。结果　联合减压治疗组有效率为 80 .4 % (37/ 4 6例 ) ,其中恢复良好、中残2 7例 (占 5 8.7% ) ,重残 10例 (占 2 1.7% ) ,死亡 9例 (占 19.6 % ) ;常规骨瓣开颅术对照组有效率为 33.4 %(17/ 5 1例 ) ,其中恢复良好、中残 6例 (占 11.8% ) ,重残 11例 (占 2 1.6 % ) ,死亡 34例 (占 6 6 .6 % ) ,两组有效率和病死率比较差异均有显著性 (P均 <0 .0 1)。联合减压治疗组患者颅内压下降速度和程度优于常规骨瓣开颅术对照组 (P<0 .0 5 )。联合减压治疗组患者的急性脑膨出、切口疝、切口脑脊液漏、外伤性癫疒间及术后枕叶脑梗死发生率均明显低于常规骨瓣开颅术对照组 (P<0 .0 5或 P<0 .0 1) ,但两组术后颅内感染发生率差异无显著性 (P>0 .0 5 )。结论　联合减压术治疗特重脑损伤合并嵌顿性脑疝患者的疗效优于常规骨瓣开颅术。     

The usefulness of detailed information to patients with contact allergy

To find out if patients with contact allergy are helped by computerized information lists, a retrospective study was carried out on 58 patients with contact allergy to lanolin, traced through our local database DALUK. All were sent a questionnaire about their usage of the information list, clearance of their eczema, their education and other details. Clearance of the patient's eczema was found to correlate with use of the information list. It was also found that the effectiveness of the information depended on factors such as education, family circumstances, ethnic background and, most of all, how and where the information list was used.     

高血糖对急性颅脑伤预后的影响

对ＩＣＵ收治的６１例急性闭合性颅脑伤患者入院２４ｈ血糖水平与急性期格拉斯哥昏迷评分、颅脑伤不同类型及预后进行分析。结果提示：格拉斯哥昏迷评分与血糖水平经回归分析呈显著负相关（ｒ＝－０．９６４，Ｐ＜０．０１）；不同类型颅脑伤患者以脑挫裂伤组血糖最高。高血糖组患者病死率明显高于非高血糖组，死亡组患者血糖明显高于恢复不良组及恢复良好组。作者认为，血糖测定有助于了解颅脑伤的严重程度，同时可以估计患者的预后，在颅脑伤的救治过程中加强血糖监测是必要的。     

颅脑外伤性病变的CT检查及其临床意义

目的：探讨颅脑外伤严重程度及CT征象与预后的关系，并探讨CT复查的最佳时间及临床意义。方法：回顾性分析80例颅脑外伤的严重程度与初次CT征象的关系，统计分析复查CT发现新病变的数目、程度及时间。结果：颅脑外伤的严重程度与初次CT征象符合率为92．5％(74／80)。外伤后即刻昏迷、CT显示重度复合伤、脑干损伤或弥漫性脑白质损伤的病死率达70．0％(21／30)。1～3d复查CT发现迟发性病变80个，4—7d21个，7d后8个。结论：临床病情与CT征象变化对判断预后有重要意义，颅脑外伤后3、7d是复查CT的最佳时机，出现病情变化应随时复查。
