OBJECTIVETo explore the correlation of ZNF217 expression to the carcinogenesis and progression of human ovarian cancer.

METHODSImmunohistochemistry and real-time RT-PCR were used to detect ZNF217 expression in human ovarian cystadenocarcinoma, ovarian cystadenoma and normal ovary tissues.

RESULTSThe expression levels of ZNF217 protein and mRNA in ovarian cystadenocarcinoma was significantly higher than those in matched ovarian cystadenoma and normal tissues (P<0.05). No significant difference was found in the expression between ovarian cystadenoma and normal ovarian tissues (P>0.05). The mRNA expression in the specimens was consistent with the protein expression of ZNF217 (P<0.05).

CONCLUSIONZNF217 gene expression is closely correlated to the occurrence and clinical stages of ovarian carcinomas, suggesting that ZNF217 can be an important candidate gene responsible for the occurrence and progression of ovarian carcinomas.

A new method for preparation of Hb solution free of stromal lipid was described. Almost all the lipid in fresh hemolysate of bovine red blood was removed with hydrophobic interaction chromatography (HIC) in the presence of 2% PEG4000, 5% PEG4000, 2%PEG10000 or 5%PEG10000. With the adding of 5%PEG4000, the 80% of recovery of Hb in HIC was obtained and the maximum lipid absorbed by hydrophobic medium, butyl agarose -6B was 86.6 mg/mL. The activity (P50) of hemoglobin preparation was 3386.4 Pa torrs, and the Hill number was 2.54, which were near to that of the native red blood cells. The mechanism of removing lipid by HIC and the function of PEG in the process were discussed.

OBJECTIVETo explore the changes in lower limb deep vein diameters, blood flow velocity and blood biochemistry in full-term pregnant women for early diagnosis and treatment of prothrombotic state.

METHODSOne hundred and twenty-eight full-term pregnant women at high risk of thrombosis (Group A), 61 healthy full-term pregnant women (Group B), and 42 healthy non-pregnant women (Group C) underwent high-resolution color Doppler ultrasound (CDU) for examining the deep veins of the lower limbs. The hematological indexes such as D-D, PLT, HGB, HCT, TT, APTT, PT, and FbgC were also observed in these 3 groups.

RESULTSCompared to Group B, the women in group A showed significantly increased diameters of the common femoral veins (CFV) and left superficial femoral vein (SFV), HCT and DD, but with significantly decreased peak blood flow in the bilateral popliteal veins (POPV) (P<0.01) and increased left POPV diameter (P=0.034). Compared to those in group C, the diameters of the bilateral CFVs, SFVs, POPV, and posterior tibial veins (PTVs) were significantly increased, but the peak blood flow in the bilateral CFVs and POPVs were significantly reduced in groups A and B; the PLT, HGB, HCT, DD, TT, APTT, PT, and FbgC also showed significant changes in groups A and B (P<0.01).

CONCLUSIONThe full-term pregnant women are at higher risk of prothrombotic state than non-pregnant women, and the full-term pregnant women with the high risk factors for thrombosis are more likely to have prothrombotic state than healthy full-term pregnant women. CDU examination of the lower limb deep veins can be of value in the diagnosis of prothrombotic state.

OBJECTIVETo detect the expression of fragile histidine triad in endometriosis and investigate the pathogenesis of endometriosis.

METHODSimmunohistochemistry was used to examine the expression of Fhit in the eutopic and ectopic endometria of 58 patients with endometriosis and in the endometria in 15 patients with hysteromyoma.

RESULTSThe intensity of Fhit expression decreased in the order of normal endometrium, eutopic endometrium in endometriosis group, and ectopic endometrium. In patients with endometriosis, Fhit expression in the eutopic and ectopic endometria in proliferative phase showed no significant difference from that in secretory phase (P>0.05). Fhit expression in the ectopic endometrium showed significant difference between different r-AFS stages. MOD of ectopic endometrium in stages I-II was significantly higher than that in stages III-IV (P<0.05), but Fhit expression in the eutopic endometrium showed no significant difference (P>0.05). MOD of ovarian endometriosis showed no difference with that of adenomyosis.

CONCLUSIONSFhit may play an important role in the development of endometriosis.

OBJECTIVETo study the effects of long-term exposure to carbon disulfide (SC(2)) on cardiovascular system of workers.

METHODSThe concentrations of CS(2) were detected in the representative workshops with different exposure levels. The indicators related to cardiovascular system were tested in 633 workers occupationally exposed to CS(2), which included blood pressure, electrocardiogram, blood routine (blood RT), cholesterol (TCHO), triglyceride (TG) and so on. The data were analyzed by chi-square test and multiple logistic regression analysis.

RESULTSThe exposure concentration of CS(2) for 389 workers was less than or equal to 5 mg/m(3), which for other 244 workers was higher than 5 mg/m(3). The maximum exposure concentration of CS(2) was 15.73 mg/m(3). There were no significant effects of CS(2) on the electrocardiogram, red blood cells, white blood cells, blood platelet, TCHO and TG of workers. However, the positive effects of CS(2) on blood pressure and negative effects of CS(2) on hemoglobin were found. The rates of high TCHO, TG and hypertension in male workers were significantly higher than those in female workers (P < 0.05). The rates of high TCHO, hypertension and sinus arrhythmia in older workers (≤ 30 years old) were significantly higher than those in young workers (> 30 years old) (P < 0.05). The rate of sinus arrhythmia in workers with 1 - 10 working years was significantly higher than that in workers with more than 10 working years (P < 0.05). The rate of hypertension in workers with 1 - 10 working years was significantly lower than that in workers with more than 10 working years (P < 0.05).

CONCLUSIONThere were no significant effects of CS(2) exposure on the indexes of cardiovascular system of workers.
