Objective To study the expression of HPV、p16 and Her-2 in the squamous cell cervical carcinoma and its chnical significance. Methods Expression of HPV16/18、p16, and C-erbB-2 and the amplification of Her-2 gene were examined using situ hybridization technique,SP immunohistochemistry,and FISH imaging analysis system in 60 cases of cervical cancer, 61 cases of CIN, and 21 cases of normal cervical tissue,respectively.Results The positive rates of HPV16/18 and p16 in the normal tissue,CIN Ⅰ -Ⅱ,CINⅢ and the squamous cell cervical carcinoma were gradually increased, they wereo (0/21),9.68 ％ (3/31),46.67 ％ (14/30),71.67 ％ (43/60);0 (0/21),19.35 ％ (6/31),93.33 ％ (28/30),96.67 ％ (58/60),respectively,and there were significant differences among the groups (P＜0.05),but no significant difference was found between the normal tissue and the CIN Ⅰ - Ⅱ. The positive rates of Her-2 and Her-2 in the CIN Ⅲ and the carcinoma were 13.33 ％ (4/30),31.67 ％ (19/60),3.33 ％ (1/30),21.67 ％ (13/60),respectively,but in the normal group and the CIN Ⅰ - Ⅱ wereo,and the differences between the carcinoma group and the CIN group,the carcinoma group and the normal group were significant(P＜0.05).The expression of Her-2 and the amplification of Her-2 were closely related to the stage, degree of differentiation and metastasis of lymph node in the squamous cell cervical carcinoma (P＜0.05). Conclusion The infection of HPV is one of thetriggers for the squamous cell cervical carcinoma.The expression of p16 and the amplification of Her-2 may be closely correlated with tumor development and high expression of p16 and Her-2 indicates poor prognosis.

Object To probe into the antihypertension activity mechanism of extracts from Compound Jueming (CJ). Methods The method of radioimmunoassay was used to assay the concentration of the related substances on spontaneously hypertensive rats (SHR) such as angiotensin Ⅱ (ANGⅡ), renin activity (RA), endothelin (ET), atrial natriuretic polypeptide (ANP), aldosterone (ALD), and urine. Results All of the three doses (9.5, 7.2, and 4.8 g/kg) of extracts from CJ reduced ANG Ⅱ and RA, but had no influence on ALD, ET, ANP, and urine in SHR. Conclusion The antihypertension effect of extracts from CJ is related to decreasing of renin angiotensin, but not to ALD, ET, ANP, and urine.

AIM: It is found that some active priciples of ginseng can enhance and activate body immune system, and have many bioactivities such as anti-tumor, anti-aging and anti-radiation. This study examined the effect of ginsenoside-Rh2 (GS-Rh2) on proliferation and apoptosis in human myeloid leukemia cell strain HL60, and analyzed the dose- and time-dependent manners of GS-Rh2. METHODS: Experiments were performed at the Department of Clinical Laboratory of Jilin Medical College from July to August in 2006. ①Rh2 was purchased from Hongjiu Biotech Co., Ltd. (batch number 050801), and prepared into 50 g/L stock solution by dissolving in pH 7.4 phosphate buffer saline. The HL60 cell strain was purchased from Shanghai Institute of Cell Biology of Chinese Academy of Sciences. ②HL60 cells in logarithmic growth phase were inoculated into 3?108 L-1 cell suspension. After the cells were cultured for 6 hours, 100 ?L GS-Rh2 at different concentrations (5,10,20,40,80 mg/L) was added respectively. After the cells were administrated for 48 hours, cell inhibition ratio (IR) was evaluated by MTT colorimetric assay. The 50% inhibitory concentration (IC50) was worked out. HL60 cell was acted with this concentration for different time (6, 12, 24, 48 and 72 hours), cell inhibition ratio (IR) at different time points was evaluated by MTT colorimetric assay, and compare it to the control. After the IC50 of GS-Rh2 acted for 48 hours, HL60 cells were observed with an inverted microscope. HL60 cell was stained by Giemsa, and the typical apoptosis cells were discovered. RESULTS: ①Dose-effect relationship: When the concentration of GS-Rh2 was 5,10,20,40 mg/L, the IR of GS-Rh2 to the growth of HL60 cells was increased gradually in obviously dose-dependent manner. The IR was similar between 80 mg/L and 40 mg/L. After the cells were administrated for 48 hours, the IC50 value was 13.0 mg/L. ②Time-effect relationship: After the concentration of IC50 of GS-Rh2 (13.0 mg/L) acting on HL60 line at different time points (6, 12, 24, 48 and 72 hours), cell IR was increased gradually (F=9.32,P

ObjectiveTo study the expressions of Ki-67 and p53 in the surface cells and polygonal cells in pulmonary sclerosing hemangioma(PSH)and investigate the relation of cell proliferation index and biological behaviour of the tumor.MethodsDouble-staining immunohistochemistry was used to detect the expressions of Ki-67 and CK8/18 protein. Double immunofluorescence staining was used to detect the expressions of p53 and AE1/AE3 protein. ResultsThe positive signal of AE1/AE3 and CK8/18 were localized in cytomembrane of surface cells. The positive signal of Ki-67 and p53 were localized in cell nucleus of the two kinds of cells.The positive rate of Ki-67 was under 1％ in surface cells and 1％-10 ％ in polygonal cells. p53 protein was mainly expressed in polygonal cells (6/9, 33.3 ％) and only exsited in seldom surface cells.ConclusionThere are differences on cellular morphous and immunophenotype between the surface cells and polygonal cells.The proliferation index and gene mutation are all predominant in polygonal cells than in surface cells. The biological behaviour of PSH maybe mainly be decided by the polygonal cells.
