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.

以ADC值1.085×10~(-3)mm~2／s作为诊断恶性淋巴结病变的临界值，敏感性及特异性分别为87.8％和91.3％。88.9％(16／18)患者WB-DWI检查后分期与临床分期一致。24例淋巴瘤患者放化疗后行WB-DWI检查，4例临床疗效为完全缓解，WB-DWI检查均为阴性，17例临床确认有肿瘤复发及明显残留，WB-DWI显示为阳性的14例，另外3例常规影像评价为部分缓解的患者，WB-DWI检查提示2例病灶以坏死液化为主，1例病灶无明显活性。13例淋巴瘤患者行多次WB-DWI检查，发现6例治疗后病灶消失，4例缓解，1例原发病灶缓解，新出现结肠癌，2例淋巴瘤进展，皆与临床相符。

From different perspectives, we get different findings and rules, which constitute the verdicts of our research, and the following are some of them.1,Apart from the objectivity, variability, polysemy and cultural specificity, the semantic features shared by body terms and other nouns, body terms owns its unique semantic features, viz systematically metaphorical and metonymical properties.

这些发现及规律，亦即本研究的主要结论，具体如下：①人体词语的语义除了跟其它普通名词的语义一样具有客观性、历时变化性、共时多义性和文化性的特征之外，还具有隐喻系统性和转喻性两个方面的独具个性特征。

Briefly, the new Nested PCR has a bright prospect of application in the microdetection of Cryptosporidium oocysts because of its high specificity and sensitivity.

And the conditions in cell suspension culture of Mikania micrantha were studied. The results showed that sucrose was the compatible carbon sucrose, and 30g/L sucrose concentration can satisfy the growth of Mikania micrantha cell; ammonium was absorbed under different sucrose concentration that haven't demonstrated significant specificity, and was completely absorbed on the lag phase and the early logarithmic phase; while nitrate was mainly absorbed on logarithmic phase. The density-dependent of Mikania micrantha cell starting to grow and density-inhibited of cell growth were proposed, the fittest inoculating quantity of Mikania micrantha in cell suspension culture was 40g/L.

并对微甘菊细胞悬浮培养条件进行研究，结果表明，微甘菊细胞生长适宜的碳源是蔗糖，并且较合适的蔗糖浓度为30g／L；在不同蔗糖浓度下氨基氮的吸收差别不大，氨基氮在迟滞期和对数期前期已基本消耗完毕，对数期生长主要利用硝基氮，因而提出，在微甘菊细胞液体悬浮培养中，氮源可以采用初始低氨基氮浓度，对数期中间维持高硝基氮，而且对数期中逐步流加少量的氨基氮；微甘菊细胞迟滞期分裂启动存在密度依赖现象，对数期生长存在密度抑制现象，最适接种量为40g／L。
