The positive expression both of p14ARF and mtp53 protein in NSCLC tissues were significantly different from that in nonmal lung tissues and tissues adjacent to the cancer (P.01).The expression of p14ARF protein was correlated with pathological degree（P＜0.01）,but it was uncorrelated with pathological staging,lymphaden metabasis and vessel invasion(P＞0.05).The expression of mtp53 protein was correlated with clinical pathology staging,pathological degree and vessel invasion(P＜0.05 or P＜0.01),but it was uncorrelated with lymphaden metabasis(P＞0.05).(2) The coexpression of p14ARF and mtp53 was 36.7％,their consistency was 38.8％,but the expression of p14ARF protein were negatively correlated with the expression of mtp53 protein(r=-0.3553,P＜0.001).Conclusion The results suggest that the decrease of p14ARF and the increase of mtp53 protein may play an important role in the genesis and development of NSCLC.

结果 (1)在正常肺组织、癌旁组织和NSCLC中p14ARF蛋白的阳性表达率分别为93.3%、83.3%、55.1%，mtp53蛋白的阳性表达率分别为6.7%、44.4%、79.6%；p14ARF蛋白和mtp53蛋白在NSCLC中的表达与正常肺组织和癌旁组织比较均有显著性差异(P＜0.01)；p14ARF蛋白表达与临床病理分期、有无淋巴结转移、有无脉管浸润无关(P＞0.05)，而与病理分化程度有关（P＜0.01）；mtp53蛋白表达与临床病理分期、病理分化程度(P＜0.01)及有无脉管浸润(P＜0.05)有关，而与有无淋巴结转移无关(P＞0.05)；(2)在NSCLC中，pl4ARF与mtp53蛋白共表达为36.7％，一致性为38.8％，二者表达呈负相关(r=-0.3553，P＜0.001)。

Focusing on such several key issues of flood utilization as resources in a basin as potentiality of flood resources in a basin, seasonal variation principle of storm flood in a basin, stage quantitative description method during flood period, computational method of stage design flood and risk design of adjustment and application of limited level of reservoir during flood season, deepgoing study is conducted in this dissertation.

论文围绕流域洪水资源利用的若干核心问题：流域洪水资源化潜力、流域暴雨洪水的季节性变化规律、水库汛期分期定量描述方法、水库分期设计洪水计算方法以及水库汛限水位调整运用的风险设计等进行了深入研究，构建了利用水库汛限水位调蓄洪水资源的理论体系和技术框架。

The mean ADC value of lymphomatous, metastatic and benign lymph nodes was (0.874±0.17)×10~(-3)mm~2/s,(0.98±0.09)×10~(-3)mm~2/s and (1.20±0.10)×10~(-3)mm~2/s. There was statistically different between benign lymph nodes and other groups (P=0.00). When an ADC value of 1.085×10~(-3)mm~2/s was used as a threshold value for differentiating malignant from benign lymph nodes, the best results were obtained with an sensitivity of 87.8% and specificity of 91.3%. 16 of 18 cases (88.9%) were accurately staged in accordance with clinical staging. For 24 patients after chemotheraphy or radiotheraphy, 4 cases were complete remission and WB-DWI was negative. WB-DWI was positive in 14 of 17 cases with recurrent or remnant tumor. For 3 patients with suspected partial remission, WB-DWI indicated necrosis in 2 cases and inactive in 1 case. Repeated WB-DWI examination was performed in 13 cases, tumors were eradicated in 6 cases, improved in 4, expanded in 2. A new colon carcinoma besides its primary lesion was found in 1 case. The results of WB-DWI were all concordant with other clinical tests.
