Methods: Mice were inoculated with tumor cells. Inhibitory effect of transfection with pCH510 on murine tumor origined from different inoculative dose and inhibiting effect of immediate transfection pCH510 after chemotherapy on tumor were observed, respectively. By cell culture technique, the influence of chemotherapeutic drug to activation of marcrophages and lymphocytes after i.p. injection of drug was observed. By cell counting method, the kinetics of the change of number of peripheral blood immunocytes induced by administration of chemotherapeutic drug was observed. The inhibitory effect of transfection with pCH510 five days after chemotherapy on murine tumor was observed.

采用瘤细胞接种建立小鼠肿瘤模型：通过基因转染，观察pCH510对不同接种量所形成的小鼠肿瘤的抑制作用以及小鼠肿瘤化疗后立即进行pCH510转染的抑瘤效果；采用细胞培养技术，观察小鼠体内注射化疗药物后，其对小鼠腹腔巨噬细胞和脾淋巴细胞激活功能的影响；采用细胞计数的方法，观察化疗药物所致小鼠腹腔巨噬细胞和外周血免疫细胞数量变化的动力学；另外小鼠肿瘤化疗后第5天进行pCH510转染，观察抑瘤效果。

T lymphocytes were distributed mainly in the middle and underneath of mucous layer before 4-day-old,but they distributed uniformly in the whole mucous layer after 4-day-old,CD4+ cells concentrated in the interfollicular areas,and both CD3+ and CD8+T lymphocytes distributed in the lamina propria and epithelium.

在定位分布变化上，4日龄之前，T淋巴细胞主要分布在黏膜层的中下部区域，而4日龄以后的各日龄在整个黏膜层中均匀分布，CD4+细胞主要聚集在滤泡间区域，而CD3+细胞和CD8+细胞在固有层中和黏膜上皮中都有大量分布。

We describe a case of NLPHL showing a variant histologic pattern characterized by small and large clusters of lymphocyte predominance cells within nodules defined by follicular dendritic cell meshworks, associated with numerous neutrophils and areas of internodular fibrosis. Focally, the neoplastic cells had lacunar cell-like cytologic features.

在此，我们描述一例组织形态特殊的NLPHL，其形态学表现为以淋巴细胞为主的细胞排列成大小不等的结节，结节均由滤泡树突状细胞网网罗，结节内见中性粒细胞浸润，部分结节间见纤维化，局灶瘤细胞呈陷窝样。
