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。

尽管目前治疗感染的措施已有很大提高，但多种微生物混合感染的发病率仍在逐渐增多，革兰阴性菌和白色念珠菌感染仍然是住院危重病人的重要致死原因。

Among pathogens , the most common pathogens associated with VAP were Pseudomonas aeruginosa ( 3013 %), Acinetobacter baumanii (1115 %), Klebsiella pneumoniae ( 1017 %), Escherichia coli ( 716 %) and S taphylococcus aureus ( 618 %). Their multiple drug2resistance to antibiotics was serious. Drug sensitivity tests indicated that the GNB had lower drug2 resistance to such antibiotics as imipenem , amikacin , piperacillin/ tazobactam , ceftazidime , cefepime , cefoperazone/sulbactam , ciprofloxacin and ticarcillin/ clavulanate. Polymicrobial pathogens were more isolated in late2onset VAP than in early2onset VAP.

A: A single negative stool examination does not exclude a parasitic infection, since the sample may have been collected during the prepatent period (i.e., the time between infection and the production of detectable ova or larvae) or because the target organism may have been shed inconsistently or in low numbers, as is frequently the case with strongyloides larvae.

一次大便虫卵和寄生虫检查的阴性结果不能排除寄生虫感染，因为样本可能在潜伏期还暂时没有异常（如在感染和产生可以检测到的虫卵或幼体前）或者所关注的微生物已经排出，或者数量太少，如类圆线虫属。
