头颈部鳞状细胞癌远处转移的相关因素分析

目的探讨头颈肿瘤远处转移的相关影响因素。方法对532例头颈部原发鳞状细胞癌患者的临床病理资料进行回顾性分析。选择性别、年龄、临床分期、T分级、N分级、原发癌部位、原发癌浸润深度、原发癌病理分级、有无颈淋巴结转移、颈阳性淋巴结数目、颈淋巴结转移累及区域、颈阳性淋巴结破膜情况等临床病理因素，用)(2检验和Logistic回归进行单因素和多因素分析，并用．Kaplan-Meier法对发生远隔部位转移患者进行生存分析。结果在532例头颈部原发鳞状细胞癌患者中，60例(11．3％)发生远处转移。单因素分析显示，临床分期(P=0．0126)、T分级(P=0．0082)、原发癌部位(P=0．0011)、原发癌浸润深度(P=0，0005)、有无颈淋巴结转移(P=0．0057)、颈阳性淋巴结数目(P=0．0149)、颈淋巴结转移累及区域(P=0．0034)、颈阳性淋巴结破膜情况(P=0．0118)与发生远处转移有关。多因素分析结果表明，仅原发癌部位、原发癌浸润深度与发生远处转移明显相关。用Kaplan-Meier法进行生存分析，结果显示60例发生远隔部位转移患者的1年生存率、3年生存率、5年生存率分别为51．7％、13．3％、6．5％。结论原发肿瘤部位和浸润深度是发生远处转移的共同决定性因素。而原发癌临床分期、T分级和有无颈淋巴结转移是头颈鳞癌远处转移的影响因素，但不是导致远处转移的初始和根本因素。喉癌、下咽癌以及原发癌侵犯肌肉、骨或软骨患者易发生远处转移。     

Autoradiographic localization of tachykinin and calcitonin gene-related peptide receptors in adult urinary bladder

PURPOSE: In bladder, sensory afferent nerve fibers contain the "sensory neuropeptides" substance P (SP), neurokinin A (NKA) and calcitonin gene-related peptide (CGRP), which interact with tachykinin NK-1 and NK-2 receptors and CGRP receptors, respectively. The purpose of this study was to examine the autoradiographic distribution of these three receptor types in the human bladder, to determine whether the anatomic location of the receptors was consistent with their known functional roles. MATERIALS AND METHODS: Specimens of urinary bladder from 9 patients (58-74 years) were obtained at cystectomy. Frozen sections of dome were labeled with [125I]-Bolton-Hunter [Sar9,Met(O2)11]-SP (NK-1 receptors), [125I]-[Lys5,Tyr(I2)7,MeLeu9,Nle10]-NKA(4-10) (NK-2 receptors) and [125I]-rat CGRP-I. Binding sites were visualized using emulsion autoradiography. RESULTS: NK-1 receptors were found over the endothelium of arterial blood vessels within the detrusor muscle and lamina propria, and over small vessels in the subepithelium. NK-2 receptors were seen over the detrusor muscle and very sparsely over blood vessels, whereas CGRP receptors were expressed densely over the smooth muscle layer of arteries and arterioles, and weakly over collecting venules. NK-1 and CGRP receptors were not observed over the detrusor muscle. CONCLUSIONS: Although the afferent nerves contain all three peptides, not all cell types express receptors for each peptide. The general distribution of receptors is in good agreement with the location of nerves, and with the known actions of SP and CGRP as vasodilator agents, and of NKA (but not SP or CGRP) in contracting the detrusor muscle.

酸相关性疾病与幽门螺杆菌感染

酸相关性疾病是指一类与胃酸攻击作用密切相关的上胃肠道疾病,包括器质性疾病和功能性疾病。根据病理生理机制的不同,酸相关性疾病主要分为胃食管反流病(GERD)、消化性溃疡病(PUD)和功能性消化不良(FD)三类。尽管目前对酸相关性疾病的发病机制已有了较深入的了解,但幽门螺杆菌(Hp)与其症状之间的关系仍不明确。现简要介绍幽门螺杆菌(Hp)感染在酸相关性疾病发生机制中的作用。     

Protective Effect of Curcumin on Endotoxin-induced Acute Lung Injury in Rats

Acute lung injury (ALI) or its more severe form, the acute respiratory distress syndrome (ARDS), is a common, devastating clinical syndrome that affects both medical and surgical patients. The most common cause of ALI is sepsis. There is now well-documented evidence that pulmonary inflammation contributes to the devel-opment of ALI. Despite significant advances in our un-derstanding of pathophysiology and technologies in the supportive management, mortality from ALI remains excessive. C…     

Antisense inhibition of methylenetetrahydrofolate reductase reduces cancer cell survival in vitro and tumor growth in vivo.

PURPOSE: Many cancer lines are methionine dependent and decrease proliferation when methionine supply is limited. Methylenetetrahydrofolate reductase (MTHFR) generates the folate derivative for homocysteine remethylation to methionine. We investigated the effect of antisense-mediated inhibition of MTHFR on survival of human cancer cells. EXPERIMENTAL DESIGN: We examined the in vitro and in vivo anticancer effects of a combination of MTHFR antisense and standard cytotoxic drugs. RESULTS: Specific antisense against MTHFR (EX5) showed significant inhibitory effects on growth of human colon, lung, breast, prostate, and neuroblastoma tumor cells in vitro compared with that of the control oligonucleotide. Cytotoxic drugs (5-fluorouracil, cisplatin, or paclitaxel) potentiated the effect of EX5. In vivo, antisense alone or in combination with cytotoxic drugs inhibited the growth of human colon and lung carcinoma xenografts. In comparison with control oligonucleotide, treatment with EX5 inhibited growth of colon tumors and lung tumors by 60% and 45%, respectively. EX5 with 5-fluorouracil decreased growth of colon tumors by an additional 30% compared with EX5 alone, and EX5 with cisplatin decreased growth of lung tumors by an additional 40% compared with cisplatin alone. Growth inhibition by EX5 was associated with decreased amounts of MTHFR protein and with increased amounts of an apoptosis marker. CONCLUSIONS: Our results confirm that MTHFR inhibition decreases tumor growth and suggest that inhibition of MTHFR by antisense or small molecules may be a novel anticancer approach.     

视网膜母细胞瘤的遗传学特征及临床筛查与治疗

视网膜母细胞瘤(RB)是儿童最常见的眼内恶性肿瘤,多发于婴幼儿,可损害患儿视力、眼球,甚至危及生命。其发生和发展与基因组和表观基因组有很大关系,遗传性RB占所有病例的45%。RB的治疗和预后取决于疾病的初始阶段,当疾病被早期诊断和治疗时,存活率超过95%,当RB在晚期发生眼外播散时,存活率低于50%。因此RB的治疗重点是通过早期肿瘤的监测和预防挽救患儿生命,其次要目标是保存眼球,并最大水平地保留视力。对RB遗传学的研究有助于通过基因筛查、监测查找特异性靶点,对提高患儿的生存率、研究RB靶向治疗十分必要。
