成人成骨细胞与珊瑚羟基磷灰石的体外生物相容性

目的：研究成人骨髓成骨细胞与珊瑚羟基磷灰石（carolline hydroxyapatite,CHA)在体外培养条件下的生物相容性。方法：抽取健康成人骨髓组织，置于含体积分数为10％胎牛血清的DMEM培养基中培养，传代后改用含地塞米松、β-甘油磷酸钠和维生素C的条件培养基培养，分为CHA复合细胞组和单纯细胞组，不同时间用倒置相关显微镜，HE染色光镜及扫描电镜观察，MTT法进行细胞增殖测定，并进行细胞微量蛋白含量和碱性磷酸酶的定量检测，结果：成人骨髓成骨细胞体外培养时复合或不复合CHA均生长良好，表现出典型成骨细胞的形态特征和生物学特性，CHA利于细胞的贴附，生长与增殖，并对细胞的功能无不良影响，结论：CHA是较理想的骨组织工程支架材料，成骨细胞复合CHA用于骨缺损的修复，具有广阔的临床应用前景。     

VEGF在膀胱移行细胞癌中的表达及意义

目的：探讨膀胱移行细胞癌中血管内皮生长因子（VEGF）的表达及其与临床病理指标的关系。方法：应用免疫组化方法对40例膀胱移行细胞癌及15例正常膀胱组织中VEGF进行检测。结果：正常膀胱移行上皮均为阴性表达；膀胱移行细胞癌中VEGF阳性表达24例，表达率为60％（24／40），明显高于正常膀胱组织（P＜0.01），其中VEGF表达阳性率随膀胱癌病理分级、临床分期上升而升高，表达强度也随之增强（P＜0.01）。结论：VEGF表达对膀胱移行细胞癌生物学行为有重要影响，VEGF有可能可作为判断膀胱癌生物学行为、转移潜能及预后指标。     

保留肾单位手术治疗早期小肾癌21例临床分析

OBJECTIVE: To evaluate the clinical effects of nephron-sparing surgery in patients with early-stage small renal cell carcinoma. METHODS: Nephron-sparing surgery was performed in 21 patients with renal cell carcinoma including 1 with solitary kidney, 3 with unilateral tumor and contralateral renal compromise, and 17 with unilateral tumor and normal contralateral kidney. The diameter of the tumors ranged from 1.5 to 6.0 cm, with a mean of 2.8 cm. The tumor diameter in 17 patients with normal contralateral kidney was less than 4 cm (mean 2.5 cm) and the average diameter in 4 patients with contralateral renal compromise was 4.2 cm. Sixteen cases were in stage T(1), 4 in stage T(2), and 1 in stage T(3). Of the 21 patients, 4 underwent tumor enucleation, 10 polar nephrectomy and 7 wedge resection. RESULTS: All patients were followed up for an average of 40.8 months (7 to 66 months). One patient suffered a right lung and mediastinum metastasis 3 years after the surgery later and 1 with chronic glomerulonephritis required dialysis 27 months after the operation. No surgical complication or local recurrence were found in other patients. CONCLUSION: As a safe and effective therapy for early-stage small renal cell carcinoma, nephron-sparing surgery can be considered as the gold-standard therapy for patients with lesions less than 4 cm in T(1) and T(2) stages of localized unilateral tumor with normal contralateral kidney.     

刘昌国教授治疗高位复杂性肛瘘经验谈

刘昌国教授，曾任新疆医科大学附属中医医院肛肠科主任，从事肛肠疾患临床研究逾四十余年，第二批名老中医学术继承专家，对于肛肠科疑难病治疗颇具心得，疗效卓越。今撷取其一加以整理记录，以飨同道。高位复杂性肛瘘是肛肠科的一种疑难病，指瘘道越过外括约肌深部以上，有两个以上外口，手术操作复杂，术中容易损伤肛门括约肌，造成肛门功能障碍，同时，术后也容易复发。自2004年2月至今，从师刘昌国老师，共诊治高位复杂性肛瘘患者12例，现分析如下：     

赤芍总苷对沙土鼠全脑缺血再灌注损伤的保护作用

OBJECTIVE: To study the protective effects of the total paeony glycoside (TPG) against global cerebral ischemia-reperfusion injury in gerbils. METHODS: Gerbils models of global cerebral ischemia-reperfusion injury were prepared by bilateral common carotid artery ligation for 12 min followed by 24-hour reperfusion. The effects of TGP on brain edema index, superoxide dismatase (SOD) activity and malonaldehyde (MDA) concentration of the cerebral tissue homogenate and pathology of the brain were examined 24 h after model establishment. RESULTS: Compared with the model group, TPG at the doses of 200 and 400 mg/kg could significantly relieve brain edema, enhance SOD activity and lower MDA concentration in the gerbils. Pathological examination showed that the gerbils with TPG treatment had milder injury of the cells in the hippocampal CA1 region. CONCLUSIONS: TPG has obvious protective effects against global cerebral ischemia-reperfusion injury.

载瘤动脉闭塞术治疗颅内巨大动脉瘤的探讨

目的总结和探讨脑血管造影和载瘤动脉闭塞在治疗颅内巨大动脉瘤上的作用及特点。方法60例颅内巨大动脉瘤患者,根据其脑血管造影的特点采取血管内介入方法[可脱式球囊和(或)弹簧圈]闭塞载瘤动脉近端53例、闭塞载瘤动脉两端后孤立动脉瘤7例;其中23例闭塞前先行颅内-外血管搭桥术。结果出院时Rankin评分分级:单纯血管内介入治疗组37例中轻残3例,合并颅内-外血管搭桥术组23例中死亡1例、重残2例。1-6年的影像学随访动脉瘤无复发。结论血管内介入结合颅内-外血管搭桥术闭塞载瘤动脉是治疗颅内巨大动脉瘤的方法之一。     

Wall-eyed bilateral internuclear ophthalmoplegia from lesions at different levels in the brainstem.

Wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) is a rarely reported syndrome. There is dispute about whether WEBINO is caused by a pontine or a midbrain lesion and whether the medial rectus subnuclei are implicated. In a study of the clinical and imaging features of four patients with WEBINO, we found that that three of four lesions involved the midbrain but not necessarily the medial rectus subnuclei.
