颈性眩晕的分型治疗及疗效分析

目的 将颈性眩晕分为上、下颈性眩晕，采取不同治疗方法并与常规治疗方法的疗效比较，以寻求更好的治疗方法。方法 将135例颈性眩晕随机分为试验组和对照组，对其治愈率及治疗时间进行统计学分析。结果 试验组的治愈率高于对照组，而试验组的治疗时间短于对照组，均有统计学意义。结论 对颈性眩晕进行分型并采用不同的治疗方法能提高治愈率，缩短治疗时间。     

Treatment of acute cerebral infarction with PGI2--evaluating the clinical effect and observation of dynamic changes in plasma TXB2 and 6-keto PGF1 alpha levels

18 patients with acute cerebral infarction were randomly subdivided into two groups: PGI2-treated group (11 cases) and low-molecular-weight Dextran-treated group (7 cases). Dosage of PGI2 was 2-5 ng/kg/min intravenous drip. Infusion was started within 72 hours after the onset of symptoms. The data showed that the plasma 6-keto-PGF1 alpha levels were increased, the plasma TXB2 levels, MAR as well as the scores of neurological deficit were decreased in the PGI2-treated group. The clinical improvement in PGI2-treated group is better than that in the dextran-treated group.

胃粘膜癌前病变的形态定量研究——胃粘膜核腺比值的定量分析

应用自动化图象分析仪对131个胃粘膜肠型病灶(单纯性肠化27个;异型增生:轻度30,中度35个,重度20个;肠型胃癌19个)进行定量分析。以单个腺管内细胞核总面积与细胞面积之比(ING)作为反映细胞核大小、数量及覆层排列程度的客观定量指标。结果发现:单纯性肠化(对照组)0.165±0.025,轻度异型增生0.21±0.023,中度异型增生0.259±0.026,重度异型增生0.32±0.028,分化型胃癌0.371±0.052,各组ING值呈正态,各组间的均值有非常显著的差异(P<0001)。因而,ING可作为胃粘膜癌前病变诊断的指标。

AdEasy1／Cbfa1诱导间充质干细胞向成骨细胞分化的实验研究

目的：观察核心结合因子a1（Cbfa1）对兔骨髓间充质干细胞（MSCs）向成骨细胞分化的诱导作用。方法：体外分离培养兔骨髓MSCs，用AdEasy1／Cbfa1。转染MSCs，在转染后3d,1、2、3和4周时，组织化学和免疫组化等方法检测成骨标志碱性磷酸酶和骨钙素的表达。结果：AdEasy1／Cbfa1转染后的兔骨髓MSCs表现出与成骨细胞相似的形态，并且表达碱性磷酸酶和骨钙素。结论：Cbfa1可诱导兔骨髓MSCs向成骨细胞分化。     

Liver and lung resection for colorectal metastasis

Aim: To examine the survival benefit of liver and lung resection for colorectal metastasis and the potential prognostic factors that affect patient survival. Methods: All patients who had resection of lung or liver metastasis for colorectal metastasis in Queen Elizabeth Hospital, Hong Kong from 1995 to 2004 were retrospectively reviewed. The overall and disease‐free survival was analysed, in particularly between liver and lung metastasis. All factors that may have affected the survival were entered into Cox's proportional hazards regression model to identify significant variables associated with survival. Results: At 5 years, the overall survival of patients who had resection of lung and liver metastasis was 44% and 38%, respectively; the disease‐free survival was 26% and 24%, respectively. Overall and disease‐free survival of patients with resection of lung metastasis was comparable to those with resection of liver metastasis. The differentiations of primary tumour and time to metastasis were shown to be significant prognostic factors influencing overall survival. Those patients with systemic chemotherapy after resection of colorectal metastasis demonstrated a significantly higher probability of overall survival. Conclusion: Resection of lung and liver metastases from colorectal origin was safe and both procedures improved survival. The use of chemotherapy after resection of metastasis significantly improved the overall survival.     

鼻内镜联合显微镜经鼻腔蝶窦及中颅窝手术

目的探讨鼻内镜下经鼻腔直接入路行蝶窦及中颅窝手术的方法. 方法鼻内镜下经较宽大一侧鼻腔将中鼻甲向外推移,鼻腔扩张器扩大视野,直达并开放蝶窦前壁, 鼻内镜与显微镜联合切除病变. 结果 10例孤立性蝶窦炎术后症状消失.6例蝶窦囊肿、脑膜瘤均一次手术切除.32例垂体腺瘤17例全切除,12例次全切除,3例大部分切除,术后补充X刀治疗.48例术后随访6个月～3.5年,平均2.5年,蝶窦囊肿、蝶窦炎、脑膜瘤无复发,3例垂体腺瘤复发,无颅内感染并发症,无鼻腔粘连、鼻出血等鼻腔并发症. 结论鼻内镜联合显微镜经鼻腔蝶窦及中颅窝手术损伤小、出血少、手术时间短、效果好.
