38例腰腿痛患者影像学检查及结果分析

目的 合理应用影像学检查,探讨腰腿痛的病因诊断,为临床治疗提供依据.方法 对38例腰腿痛患者进行随访,观察普通照片后经CT、MRI及B超等复查的最后诊断,对比进行分析.结果 单纯普通照片对椎间盘脱出、椎管狭窄、骶部硬膜外囊肿、股骨头无菌坏死、梨状肌损伤等疾病缺乏直接征象,不能作为诊断依据.结论 应用CT、MRI现代影像技术,同时借助B超、肌电图等相关检查,是确诊腰腿痛病因的有效方法.     

487例垂体腺瘤伽玛刀治疗后内分泌学远期效果分析

目的 评估487例垂体腺瘤行伽玛刀治疗后内分泌方面的改变,并分析性功能的改善情况.方法 对487例垂体腺瘤患者进行立体定向伽玛刀治疗,对他们作半年到7年的随访,记录其血液内分泌的水平和性功能的状况并进行了分析.结果 在随访的患者中,PRL腺瘤和GH腺瘤内分泌水平分别有53.7%、31.8%降至正常,而分别有24.2%、45.5%继续升高;在PRL腺瘤伽玛刀术后内分泌水平继续升高的患者中,有较高比例是术后自行停止服用溴隐亭;无功能型、PRL型、GH型、混合型垂体腺瘤性功能明显改善分别为1.7%、28.8%、10.8%、20.0%.结论 立体定向伽玛刀放射外科治疗垂体腺瘤可以改善内分泌学方面的异常,单从这一角度分析该方法可以作为垂体腺瘤的首选治疗,并完全替代传统的分次放疗.伽玛刀治疗后仍然需要继续服用溴隐亭.伽玛刀治疗可以改善垂体腺瘤患者的性功能;但为了更好的改善性功能,提倡对垂体腺瘤(包括垂体微腺瘤)进行早期的立体定向伽玛刀治疗.     

Alberta早期CT评分的临床应用

超早期溶栓被公认为脑血栓形成最有效的治疗手段，但是，什么样的患者最适合溶栓治疗，目前还没有一种公认的标准。有学者提出用一种基于CT早期缺血性改变的半定量方法——Alberta早期CT评分（ASPECTS）来选择适合溶栓治疗的患者。ASPECTS是一种仅适用于评价大脑中动脉（MCA）供血区缺血改变的量表，其总分为10分。ASPECTS=10分提示MCA供血区无早期缺血征象，ASPECTS=0分表示MCA供血区广泛缺血，提示MCA主干闭塞。多数学者认为，ASPECTS〉7分的患者是溶栓治疗的最佳候选者，而当ASPECTS≤7分时，溶栓治疗不但不能改善症状，反而会增高颅内出血的风险。然而，对ASPECTS的溶栓治疗选择标准仍然存在一些不同的看法，文章就ASPECTS的具体操作及其在临床实践中的应用进行了综述。     

Neurochemical studies on the mesolimbic circuitry of antinociception

Previous studies using the technique of microinjection into brain nuclei indicated that the periaqueductal gray (PAG), nucleus accumbens, habenula and amygdala play an essential role in pain modulation and that these nuclei possibly act through a ‘mesolimbic neural loop‘ to exert an analgesic effect, in which Met-enkephalin (MEK) and β-endorphin (β-EP) have been implicated as the two major opioid peptides involved in antinociception. In the present study performed in rabbits, intracranial microinjection was supplemented with push-pull perfusion and radioimmunoassay to determine whether the release of enkephalins (ENK) and β-EP was increased in these nuclei when the putative neural circuit was activated by morphine administered into one of the nuclei. The results showed: (1) microinjection of morphine into the PAG increased the release of ENK and β-EP in the N. accumbens, and vice versa; (2) microinjection of morphine into the N. accumbens increased the release of ENK and β-EP in the amygdala, and vice versa; (3) morphine microinjected into the PAG caused an increase in the release of ENK and β-EP in the amygdala and vice versa, although the release of ENK in PAG was statistically not significant. These results indicate that PAG, N. accumbens and amygdala are connected in a network served by a positive feedback circuitry.     

食管癌患者血缘亲属及不同性别食管癌患病风险比较研究

目的 对比分析食管癌病例组与对照组血缘亲属食管癌患病风险,并了解食管癌家族中危险亲属人群患病的新线索.方法 采用病例对照研究方法 ,对食管癌病例组及对照组各720例进行逐层分析,以比较两组各血缘亲属父系、母系食管癌患病危险度(OR)的大小及差异.结果 (1)病例组Ⅰ级亲属食管癌患病危险度(1.34%～2.24%)显著高于对照组(0.78%～1.21%)(P＜0.01);Ⅰ级亲属中病例组父母亲食管癌患病危险度为6.11%,显著高于对照组父母亲食管癌患病危险度2.97%(P＜0O01).(2)以血缘亲属中父系和母系亲属逐层分析可见,病例组父系食管癌患病危险度(0.87%～1.01%)与母系患病危险度(0.50%～0.79%)均显著高于对照组父系食管癌患病危险度(0.53%～0.65%)与母系患病危险度(0.38%～0.47%)(P＜0.05).进一步分析显示,病例组父系中男性亲属与母系中女性亲属,即父系中祖父、父亲、叔伯食管癌患病危险度为2.68%与母系中外祖母、母亲、姨的食管癌患病危险度1.91%均显著高于对照组父系中男性亲属食管癌患病危险度1.50%与母系中女性亲属食管癌患病危险度0.92%(P＜0.01).结论 山西省食管癌患者血缘亲属发病危险主要是父亲及其兄弟、母亲及其姐妹,其下代患食管癌风险要大.

Liposome-mediated transfer of vascular endothelial growth factor cDNA augments survival of random-pattern skin flaps in the rat.

Tissue engineering is an application for gene therapy that is in its infancy. We show that simple liposomal-mediated gene transfer could result in a potentially useful biological effect in the field of wound healing. cDNA encoding the 165 amino acid form of vascular endothelial growth factor complexed to commercially available liposomes was injected into rat skin 1 week before raising a random pattern 3 x 10 cm flap. The flap survival was enhanced by 14 percent, and was accomplished without accessing the arterial inflow of the territory. These results were statistically significant (p<0.002) and reproducible. No adverse effects were seen. Histological analysis of the angiogenesis localized much of the new vessel formation to the area around the hair follicles. Polymerase chain reaction amplification of extracted flap tissue confirmed the presence of the transgene.
