1.Objective To diagnose a Chinese benign familial neonatal convulsions (BFNC) family at the level of gene and investigate its molecular pathogenesis.
目的 对一个中国良性家族性新生儿惊厥 (benign familial neonatal convulsions,BFNC)家系进行基因诊断 ,并探讨其分子发病机理。
2.Of these tumors, 94% were marked with vimentin (94.6% benign and 93.8% malignant), 65.3% were marked with HHF-35 (67.6% benign and 64% malignant), 23.8% were marked with desmin (37.8% benign and 15.6% malignant) and 22.8% were marked with S-100 protein (27% benign and 20. 9% malignant).
101例中,94％Vimentin阳性(良性94.6％,恶性93.8％),65.3％HHF—35阳性(良性67.6％,恶性64％),23.8％Desmin阳性(良性37.8％,恶性15.6％)和22.8％S—100蛋白阳性(良性27％,恶性20.9％)。
3.a benign smile; the benign sky; the benign influence of pure air.

4.Methods:Microvessel density (MVD) was examined by immunohistochemical stain in thirty seven cases of ovarian cancer tissue (malignant group),thirty cases of benign ovarian tumor tissue (benign group),and twenty six subjects of norma l ovarian tissue (normal group),respectively. The expression of VEGF was examin ed in ovarian cancer at the same time.
方法:应用免疫组织化学染色技术分别检测37例卵巢癌组织(恶性组)、30例良性卵巢肿瘤组织(良性组)和26例正常卵巢组织(正常组)中的微血管密度(MVD),同时测定卵巢癌组织中VEGF的表达水平。
5.The X-ray studies showed 41.4% cases with benign finding, 9.4% were suspected to be ben ign and 49.2% malignant The authors considered that it is difficult to differentiate benign lung mass from malignant only by X-ray.
X线诊断符合良性者41.4％,可疑良性者9.4％,拟有恶性者49.2％。
6.Methods: A research assay was used to measure LPA levels in plasma from 57 patients with ovarian carcinoma,66 patients with ovarian benign disease and 37 healthy control women in the Clinical Medical College of Yangzhou University from January 2002 to January 2004 . The RT-PCR was used to determine the mRNA expression of Edg-2/Edg-7 in ovary of 16 healthy control women ,24 patients with ovarian carcinoma and 32 patients with ovarian benign disease.
方法:测定卵巢恶性肿瘤57例、良性肿瘤66例及健康对照37例血浆LPA水平,并用RT-PCR方法检测其中正常卵巢组织16例、卵巢恶性肿瘤24例及卵巢良性肿瘤组织32例Edg-2/Edg-7mRNA的表达情况。
7.(2) Differential diagnosis of bile duct benign lesions did not get enough regards, and bile duct benign lesions were sometimes misdiagnosed and treated as BDC.
（2）胆管良恶性病变的鉴别诊断未引起足够的重视，将胆管良性病变误当胆管癌治疗时有发生。
8.Methods Reverse transcriptase-polymerase chain reaction (RT-PCR) technique was used to detect the CK20 mRNA in peripheral blood of 56 patients with gastric cancer(gastric carcinoma group), 18 patients with benign gastric disease(benign gastric disease group) and 20 cases of control group.
方法应用逆转录-聚合酶链反应(RT-PCR)检测56例胃癌(胃癌组)、18例良性胃病(良性胃病组)、20例正常献血者(对照组)外周血中CK20mRNA的表达情况。
9.Using radioimmunoassary(RIA)、polymerase chain reaction(PCR) and high performance liquid chromatography (HPLC), We have determined tuberculin deoxyribonudeic acid (TB-DNA)、carcino-embryonicantigen (CEA) of the tumor-associated amino acid (AA) in 106 benign and malignant ascites (benign 35、tuberculosis 35 and malignant 36).
应用放射免疫法（RIA）、聚合酶链反应（PCR）法和高效液相色谱法（HPIC）对106例良、恶性腹水（良性组35例、结核组35例、恶性组36例）进行了结核菌DNA（TB－DNA）、肿瘤相关抗原（TAA）的癌胚抗原（CEA）、糖链抗原（CA19－9、CA50）和17种氨基酸（AA）测定分析。
10.Results The OD value of benign cell group was 0.514±0.023,while in malignant cell group,it was 0.647±0.026.Conclusion This method can detect the benign or malignant of tumor based on NSE level of pheochromocytoma cell ,which is a good laboratory index.
结果良性嗜铬细胞瘤细胞组的OD值为 0 .5 14± 0 .0 2 3 ,而恶性组的OD值为 0 .64 7± 0 .0 2 6。 结论可以依据嗜铬细胞瘤细胞NSE水平的高低检测出肿瘤的良恶性 ,为进一步诊治嗜铬细胞瘤细胞提供了实验依据
