巨噬细胞移动抑制因子与鼻咽癌微血管生成和淋巴结转移的关系

[目的]研究巨噬细胞移动抑制因子(macrophage migration inhibitory factor,MIF)和血管内皮生长因子(vascular endothelial growth factor,VEGF)在鼻咽癌组织中的表达水平及其与肿瘤新生血管的关系,探讨细胞因子在鼻咽癌细胞侵袭转移过程中的作用.[方法]收集1999-2003年期间45例确诊未治的鼻咽原发癌活检组织标本,用LSAB免疫组化法检测鼻咽癌组织中MIF和VEGF表达,计数癌组织中新生血管热区的CD34阳性微血管密度(intratumoral microvessel density,IMD),并将各检测指标与患者的病理及临床资料相联系.[结果]鼻咽原发癌组织中,癌细胞MIF和VEGF的阳性表达率分别为78%(35/45)和71%(32/45),伴有淋巴结转移的癌组织中MIF和IMD水平均高于无淋巴结转移的癌组织,P=0.029,P=0.026,MIF阳性组的IMD计数为(35.1±13.3)/高倍视野,明显高于MIF阴性病例的(20.9±10.2)/高倍视野,P=0.003.以Schmincke型生长方式分布的癌细胞MIF表达水平(67.4%±35.2%)高于以Regaud型方式分布的癌细胞(32.9%±29.7%),P=0.007.癌细胞MIF与VEGF表达以及IMD计数均显示正相关关系,P＜0.05.但癌细胞VEGF的表达与患者性别、年龄、病理组织学分型以及临床分期无统计学显著意义.[结论]MIF在鼻咽癌细胞的淋巴结转移过程中可能具有重要的促进作用,并可能是影响肿瘤性微血管生成和癌细胞VEGF表达的重要因素.

Influence of moderate hypothermia on cerebral oxygenation in pigs with intracranial hypertension

BACKGROUND: Moderate hypothermia is one of the effective therapeutic methods for head injury in recent years, there are many mechanisms of moderate hypothermia for brain protection, and its influence on cerebral oxygenation is also one of them. OBJECTIVE: To observe the influence of moderate hypothermia on cerebral oxygenation of animals with acute intracranial hypertension, and further investigate the protective mechanism of moderate hypothermia. DESIGN: A randomized controlled trial. SETTING: Department of Neurosurgery, Renji Hospital affiliated to the Medical College of Shanghai Jiao Tong University. MATERIALS: Twenty healthy little pigs, either male or female, weighing 4.5–5.5 kg, were used. Neurotrend-typed multiparameter monitoring system (Diametrics Company, British); CMA/100 micro-injection pump (Carnegie Company, Sweden). METHODS: The experiment was conducted in the Changzheng Hospital affiliated to the Second Military Medical University of Chinese PLA in November, 2001. The pigs were randomized into two groups: the normothermia group (control group, n =10) and moderate hypothermia group (n =10). ① Bilateral femoral arteries were separated, one was connected to pressometer for monitoring mean arterial pressure (MEP), and the other for analysis of blood gases [including peripheral blood pH value, arterial partial pressure of carbon dioxide (PaCO2), arterial partial pressure of carbon dioxide (PaCO2), HCO3–]. ② Rectal temperature was monitored with mercurial thermometer. ③ Intracranial pressure was monitored using Camino optic ICP probe placed in the subdural space. ④ Neurotrend multiparameter monitoring sensor was inserted into the white matter for about 4 cm to determine cerebral perfusion pressure (CPP, CPP=MAP(ICP), brain tissue partial oxygen pressure (PO2), partial pressure of carbon dioxide (PCO2), HCO3– and brain temperature. The rectal temperature of animals in the moderate hypothermia group was lowered to 34 ℃ using ice bags, and the body temperature was maintained at 33–35 ℃ for 2 hours. The changes of the parameters were observed continuously, and the pigs in the normothermia group were not treated with cooling. MAIN OUTCOME MEASURES: ① MAP, ICP, rectal temperature, CCP; Indexes of cerebral oxygenation detected with Neurotrend-typed multiparameter monitoring system; ② Results of blood gases analysis in the moderate hypothermia group. RESULTS: All the 20 pigs were involved in the analysis of results. ① MAP, ICP, rectal temperature, CCP and indexes of cerebral oxygenation: In the moderate hypothermia group, the ICP after cooling was obviously lower than that before cooling [(3.31±1.19), (5.33±0.95) kPa, P < 0.05], CCP was higher, brain tissue PCO2 [(12.03±1.73), (10.59±2.01) kPa, P < 0.05], and brain tissue pH value was higher [(7.03±1.63), (9.40±1.30) kPa, P < 0.05], whereas the brain temperature was decreased as compared with that before cooling [(34.9±0.3), (37.2±0.2) ℃, P < 0.05]. ② Results of blood gases analysis in the moderate hypothermia group: There were no significant differences in the parameters of peripheral arterial blood gases analysis before and after cooling in the moderate hypothermia group (P > 0.05) CONCLUSION: Moderate hypothermia will not impair the cerebral oxygenation, and it can reduce brain tissue CO2 and decrease brain tissue acidosis.
