To study whether the development of hypertensive disorder complicating pregnancy is associated with -308G-->A, -850C-->T mutation at promoter of TNF-alpha gene, the -308G-->A, -850C-->T polymorphism was examined in patients and healthy pregnant women by PCR-RFLP technique. The frequencies of genotype and allele were compared between the two groups. The results showed that with -308G-->A polymorphism distribution, the allele frequency of TNF2 and the frequency of the genotype TNF2/1 in the patient group was significantly higher in the patient group than in control group (P<0.05). A significant difference in genotype distribution of -850C-->T polymorphism was observed between the two groups. The allele frequencies of T in patient group was higher in the control group as compared with the patient group. The frequencies of CT and TT genotypes were lower in the patient group. It is concluded that the TNF2 allele of -308 is associated with the occurrence of hypertensive disorder complicating pregnancy, while T allele of -850 may be the protective factor against the development of the disease. TNF2/1 CC may be susceptibility genotype of hypertensive disorder complicating pregnancy.

OBJECTIVE To investigate the productive rate of AmpC ?-lactamases and ESBLs produced by the Gram-negative bacilli from the nosocomial infection in our hospital. METHODS AmpC ?-lactamases and ESBLs were detected by the improved cefotaxime and ceftriaxone three-dimensional test. RESULTS The productive rate of AmpC ?-lactamases was 16.00%.Among them,the productive rate of AmpC ?-lactamases was only 8.84%.The Enterobacter cloacae,Serratia marcescens and Enterobacter aerogenes were easy to produce the enzymes(36.00%,31.25% and 28.00%).The productive rate of AmpC ?-lactamases and ESBLs at the same time was 7.16%. CONCLUSIONS The productive rate of the enzymes by the Gram-negative bacilli from the nosocomial infection is rather high.

Objective To investigate the radiosensitivity effects of poly ADP-ribose polymerase-1 (PARP-1) inhibitor 3-amion benzamide (3-AB) on the BRCA non-mutant and BRCA mutant breast cancer cells,and to explore the regulatory mechanism of PARP-1 and BRCA in radiation-induced DNA damage repair.Methods MDA-MB-436 cells and MDA-MB-231 cells were divided into four groups respectively as the control (CTRL),ionizing radiation alone (IR),3-AB alone (3-AB),and ionizing radiation combined with 3-AB(IR + 3-AB)group.γ-H2AX foci were detected by immunofluorescence assay.The radiosensitivity of breast cancer cells was evaluated by clonogenic survival assay.The percentage of apoptotic cells was assessed by flow cytometry.Results Compared with MDA-MB-231 cells,MDA-MB-436 cells had a higher radiosensitivity and produced more γ-H2AX foci(t =4.57,P < 0.05),which was further increased by 3-AB.The DNA damage of MDA-MB-436 cells in the IR + 3-AB group was the most remarkable (t =3.26,P < 0.05).Flow cytometry showed that the cells in the IR + 3-AB group had the highest rate of apoptosis (t=3.81,P < 0.05),and the apoptosis rate of MDA-MB-436 cells was significantly higher than MDA-MB-231 cells (t =2.96,P < 0.05).Conclusions The radiosensetivity of BRCA mutant cells MDA-MB-436 is significantly higher than that of non-BRCA mutant cells MDA-MB-231.Inhibition of PARP-1 can further increase the apoptosis and radiosensitivity of BRCA-mutant cells by further blocking the repair of DNA single-strand break induced by ionizing radiation.

This study examined the role of PI3K/Akt pathway in radiosensitization of DNA damage of cervical carcinoma cells. The 50% inhibition concentration (IC(50)) of cisplatin and docetaxel in HeLa cells was detected by Mono-nuclear cell direct cytotoxicity assay (MTT) in vitro. HeLa cells were treated by cisplatin/docetaxel of 10 percent of IC(20) alone or combined with LY294002 for 24 h, and then radiated by different doses of X-ray. The cell survival ratio was obtained by means of clone formation. One-hit multi-target model was fitted to the cell survival curve to calculate dose quasithreshold (Dq), mean lethal dose (D(0)), 2Gy survival fraction (SF(2)) and sensitization enhancement ratio (SER). The pAkt and total Akt expression was detected by Western blotting and DNA damage by neutro-comet electrophoresis. The HeLa cells were randomly divided into 7 groups in terms of different treatments: Control; radiation treatment (RT) group; LY294002+RT group; cisplatin+RT group; docetaxel+RT group; LY294002+cisplatin+RT group; LY294002+docetaxel+RT group. The apoptosis ratio of each group was measured by flow cytometry. The results showed that docetaxel and cisplatin significantly enhanced the phosphorylation of Akt in radiation-treated HeLa cells. The Dq, D(0) and SF2 in LY294002-contained groups were lower than those in docetaxel or cisplatin+RT group. The SER in the LY294002+docetaxel+RT group was 1.35 times that of the docetaxel+RT group, and that in the LY294002+cisplatin+RT group 1.26 times that of the cisplatin+RT group. The Comet electrophoresis showed that tail distance in the LY294002+cisplatin+RT group or LY294002+docetaxel+ RT group was longer than in the cisplatin+RT group or docetaxel+RT group. The apoptosis ratio in the LY294002+cisplatin+RT group or LY294002+docetaxel +RT group was higher than in the cisplatin+RT group or docetaxel+RT group. It was concluded that inhibiting PI3K/Akt pathway can increase the effect of docetaxel and cisplatin on the radiosensitivity of HeLa cells and DNA damage resulted from radiation.
