Results 31 cases of patients with biliary calculi in 46 cases (of which 30 cases with intraoperative findings basically the same, one cases of distal common bile duct stones misdiagnosed as ampulla negative tumors), The qualitative and positioning accuracy rates were 96.8% and 100% respectively;In 15 cases of patients with biliary andpancreatic tumors (9 cases of cholangiocarcinoma, 1 cases of gallbladder carcinoma, pancreatic cancer 2 cases, 1 ampullary cancer and 1 cases of congenital cysts), 14 cases were correctly diagnosed, The qualitative and positioning accuracy were 93.3% and 100% respectively.

结果 46例患者中31例胆道结石（其中30例与术中所见基本一致，1例胆总管下端阴性结石误诊为壶腹部肿瘤），定性、定位准确率分别为96.8％、100％；15例胆胰肿瘤患者中（9例胆管癌、1例胆囊癌、2例胰头癌、1例壶腹部癌、1例先天性但总管囊肿），14例得到正确诊断，定性、定位正确率分别为93.3％、100％。

Gardnerella +Mh, Clue cell ratio being better concordance with Amsel and Nugent on BV diagnosis may be a good diagnosis supplement for patients who clinical symptom was diagnosed no-BV by Asmel.

阴道加德纳菌＋Mh、线索细胞阳性比率与Amsel结合Nugent法诊断BV具有高度一致性，对于经Amsel检测阴性但有临床症状的患者的BV诊断和严重程度评估是一个有益的补充。

Fluorescent instruments.the colonies of the specimens yielding growth were identified by the vitek32 instruments and kb method was used for the drug sensitivity tests.results three hundred and thirtyone bacteria strains were isolated from a total of 3104 blood culture specimens,with a positive rate of 10.7%.of the identified bacteria,g+ cocci accounted for 50.3%,g-bacilli accounted for 44.7%,fungi accounted for 3.0%,and anaerobian accounted for 1.1%.the susceptibility rates of g-bacilli to imipenem,amikacin and cefoperazone/sulbactam were high.the susceptibility rate of g+ cocci to vancomycin and imipenem were also high.conclusion g+ cocci prevail over g-bacilli in the blood specimens.the staphylococci are the chief bacteria in the childrens blood specimens.both g+ cocci and g-bacilli are sensitive to imipenem.

结果 在3 104份血液培养标本中分离出病原菌331株，阳性检出率为10.7%。病原菌以革兰阳性需氧球菌居首位（50.3%），革兰阴性需氧杆菌次之（44.7%），真菌占3.0%，厌氧菌占1.1%。血液培养中的g+球菌对万古霉素和亚胺培南较为敏感，g-杆菌对亚胺培南、舒普深、丁胺卡那较为敏感。结论血液培养病原菌以g+球菌为主，g-杆菌次之；儿童血液培养病原菌以葡萄球菌属为主；亚胺培南对g+球菌和g-杆菌均具有较高的敏感率。

Objective To determine the value of contrast ultrasound for evaluating tumor angiogenic activity and its prognostic significance in axillary-node-negative breast carcinoma.

目的探讨超声造影对腋淋巴结阴性乳腺癌血管生成的定量检测及与其生物学行为的关系。

In 2 dogs with suspect MRA diagnosis, one was found positive and one negative by angiograph.

MRA诊断为可疑阳性的2只犬，血管造影证实1只为阳性，另1只为阴性。

Serum non-HDL-C level in the positive angiograph group was significantly higher than that in the negative group (P.01), increased with the number of affected vessels.

结果：①冠脉造影阳性组血清non-HDL-C显著高于阴性组(P.01)，并且随冠脉病变支数增多，血清non-HDL-C水平也增高。

Logistic regression analysis showed that the OR value of non-HDL-C is 1.032 (95% CI 1.011-1.049) for the positive angiograph group and the negative group, 1.007 (95% CI 1.002-1.012) between one vessel lesion and multi-vessel lesions, better than LDL-C. 3. The multivariant stepwise regression analysis of the vessel number, severity and lipids of coronary artery lesions showed that non-HDL-C was the best indicator in the male patients group who were under the age of 55 years.

Logistic回归结果显示在冠造阳性和阴性、1支病变与多支病变的比较中non-HDL-C的OR值分别是OR=1.032(95% CI1.011-1.049)和OR=1.007(95%CI1.002-1.012)，略强于LDL-C；③冠状动脉病变支数、程度与脂质成份的逐步回归显示，non-HDL-C是年龄小于55岁的男性患者组中最主要的相关因素。

Results 520 arteries were examined in all, and DSA detected 130 normal, 390 abnormal (75.0%, 120 artherosclerosis, 201 stenosis, 69 occlusion). In the diagnosis of MRA to angiostegnosis , the sensitivity was 95.4%, the specificity was 96.2%, the false positive was 1.3%, and the false negative was 17.7%.
