Objective To investigate the clinical value of combined detection of the serum levels of CA125,CA72-4 and tumor specific growth factor(TSGF)in the diagnosis of ovary cancer and the curative effect.Methods Serum levels of CA125,CA72-4 and TSGF in 68 patients with ovary cancer,53 patients with benign ovary rumor and 50 normal controls were measured by chemiluminescent immunoassay(CLIA)and chemical colorimetry.Results and clinical data were statisticaly analyzed.Results The levels of CA125,CA72-4 and TSGF in ovary cancer group were higher than that in the benign ovarian tumor group and healthy controls(all P ＜0.01).When use three tumor markers united detection,sensitivity,specificity and accuracy were 91.2％,83.0％ and 87.4％ respectively.The sensitivity and accuracy was higher than any single detection.The specificity with single CA125 testing was consistently.The levels of CA125,CA72-4 and TSGF in patients with ovary cancer were significantly different after surgical treatment for five days(all P ＜0.05).Conclusion The combined detection of the three markers may increase the positive rate in the early diagnosis of ovarian cancer,and help to differentiate the benign and malignant ovarian tumor,but also is valuable to observe the curative rate and postoperative monitor of the ovary cancer.

Object To solve the problem of low growth rate an d metabolism level in Taxus chinensis var. mairei (Lem?e et L?vl.) Cheng et L. K. Fu Methods Cells on logar it hmic phase (20 d) and stationary phase (30 d) were subcultured individually. Th euptake of carbohydrate, nitrogen and phosphate from the medium was examined, th e growth rate of Taxus cell and the synthesis of taxol were anal y zed too during the whole growth period Results The Taxus cell subcultured at logarithmic phase uptook carbohydrate and nit rate earlier than that subcu ltured at stationary phase. The special growth rate of the former was 1.5 folds of that of the latter. The production rate of taxol was increased by nearly 4 ti m es Conclusion Subculturing at logarithmic phase will benefi t the biomass accumulation and the taxol synthesis

Objective To explore the significance of interleukin -35 (IL -35)in serum of patients with severe hepatitis.Methods Collected 39 cases of chronic hepatitis B(CHB)patients and severe hepatitis,and col-lected 19 cases of healthy control's(HC)peripheral blood at the same time.ELISA method was used to detect IL -35 levels.Results IL -35 in CHB and severe hepatitis group [(483.5 ±280.7)ng/mL and (277.9 ±248.7)ng/mL] were higher than HC group (50.5 ±47.8)ng/mL(t =2.089,3.303,P =0.044,0.002).In severe hepatitis group, the IL -35 levels in survivors group (305.3 ±301.2)ng/mL was higher than death group (78.7 ±33.2)ng/mL (P =0.012).IL -35 was positively correlated with ALT and AST,the correlation coefficient were 0.649 and 0.599. Conclusion IL -35 is involved in the pathogenesis of hepatitis B process,the low serum IL -35 levels in severe hepatitis patients may herald a bad prognosis.

Objective To explore the changes of interleukin -33 in serum of patients with chronic severe hepatitis B.Methods 25 patients with mild chronic hepatitis B ( MCHB group) and 25 patients with severe chronic hepatitis B(SCHB group) were collected.18 healthy people were collected as control (HC group).ELISA method was used to detect IL -33 level in peripheral blood .Results The IL-33 levels in MCHB and SCHB group were (11.7 ±6.9)ng/L and (16.5 ±9.1)ng/L,respectively,which were significantly higher than (5.1 ±2.9)ng/L in HC group(t=4.037,5.434,P=0.000,0.000).The IL-33 level in MCHB group was lower than that in SCHB group(t=2.108,P=0.040).The IL-33 level was positively correlated with ALT ,AST and HBV DNA(r=0.526, 0.568,0.285,P=0.000,0.000,0.045 ).Conclusion IL -33 is involved in the pathogenesis of hepatitis B . IL-33 plays an important role in HBV -relate injury.
