Nuclear factor E2 related factor Nrf2 is a nuclear transcription factors involved in a variety of protein expression. As a center of oxidative stress regulation, it combines with antioxidant components (antioxidant responsive element, ARE) and activates downstream multiple anti-oxidation, anti-inflammatory and detoxifying enzyme protein expression. This signaling pathway is involved in the development of inflammation, tumor and other pathological process. This review describes the basic structure, biological effects and signaling pathways of Nrf2, summarizes the latest progress about mechanisms of factors, which are involved in the positive and negative regulations of signal pathway, providing a new target for anti-inflammatory, antioxidant, and antitumor biochemical treatment. Based on these, the paper also looks forward to applicating bioinformatics technology and providing better prospects for the development of target intervention.

Recurrent pregnancy loss (RPL) is a common complication of pregnancy, which affects 2%fertile women. A recent research has found that high level of thrombin-activatable fibrinolysis inhibitor (TAFI) can reduce the occurrence risk of early RPL. TAFI is one kind of carboxypeptidase, which can be activated as TAFIa. TAFIa can make the fibrinolysin lose its working site, which can interact with the fibrin to play a role in the regulation of fibrinolysis and the inhibition of throm?bus formation. The damage of fibrinolytic system is one of the risk factors for the occurrence of RPL in pregnant women, which has become one of the hotspots in the medical profession. In this paper, recent literature on TAFI and its relationship with recurrent pregnancy loss has been reviewed, hoping for new ways and clues in clinical treatment and prevention of RPL.

Objective:To compare the therapeutic and toxic profile of topotecan given intraperitoneally with intravenously in human ovarian cancer xenografted into athymic nude mice.Methods: Eighty female Balb-c/nu-nu mice were randomized assigned into eight groups (n=10). Xeneografts resulted from intramesentery injection of cultured human ovarian cancer cells SKOV3 in athymic mice. Onset of intraperitoneal treatment with either topotecan or cisplatin (7.5 mg/kg) was on day 7. Animals scheduled for topotecan i.p. received intraperitoneal application of topotecan (1.5 mg/kg×2, 3.0 mg/kg×2, 6.0 mg/kg×2 or 10.0 mg/kg×1). Animals scheduled for topotecan i.v. received intravenous administration of topotecan (6.0 mg/kg×2 or 10.0 mg/kg×1). Two weeks after drug application animals were killed. Tumor growth inhibition were assessed and compared with untreated mice and cisplatin intraperitoneally administered mice. Acute toxicity was determined by loss of body weight. Cell cycle division and apoptosis after drug administration was determined by flow cytometric analysis.Results: In a panel of ten tumour xenografts, intraperitoneal topotecan was significantly more effective than intravenous administration. The toxicity profile suggested a better tolerability in terms of weight loss after intraperitoneal administration than cisplatin control. Topotecan 10.0 mg/kg i.p. per day (1 day) schedule was an optimal treatment for ovarian cancer and well tolerated by mice with no signs of acute toxicity. Topotecan and cisplatin induce cells G0-G1 arrest and apparent apoptosis. No significant difference among mice treated with topotecan intraperitoneally or intravenously or cisplatin was observed in term of apoptosis and cell cycle perturbation.Conclusion:The results may have implications for the future design of clinical studies on intraperitoneal application of topotecan. It suggests that apoptosis and cell cycle perturbation play an limited role in the mechanism of topotecan administration.

Objective:This study investigated the prognostic significance of age at diagnosis, stage, tumor subtype, pelvic lymph node metastasis (PLNM), lymph-vascular space involvement (LVSI), presence or absence of deep cervical stromal invasion (DCSI) in stage ⅠB-ⅡA cervical cancer patients. It also investigated the inter-relationship among these factors. Methods: 152 patients treated with radical hysterectomy plus pelvic lymphadenectomy were followed up for a median of 49 months and were evaluated retrospectively. Results: The 5-year overall survival rate was 84.8%. The distribution of age at diagnosis is of bimodal shape, peaking at 42 and 68 years, respectively. Tumor subtype, PLNM, DCSI, and LVSI were found to be significant prognostic factors individually. After multivariate analysis, only tumor subtype and PLNM were found to be independent, significant prognostic factors for survival. The prognostic importance of LVSI appeared to be eclipsed by the presence of PLNM. DCSI was statistically related with FIGO stage, LVSI and PLNM. Conclusion: Tumor subtype and PLNM are the two most important independent prognostic factors for stages ⅠB-ⅡA cervical cancer. Some prognostic factors are inter-related and may reflect different facets of tumor progression.

Objective To observe the effects of deep electroacupuncture on carlilage tissue in knee osteoarthritis (KOA) rabbits. Meth-ods 40 New Zealand rabbits were randomly divided into normal group (A, n=10) and model group (n=30). The model group was modeled KOA with Hulth-Telhag way, and identified with X-ray. Then they were divided into no-treated group (B, n=10), deep electroacupuncture group (C, n=10) and routine electroacupuncture group (D, n=10) randomly. The groups C and D accepted electroacupuncture since 6 weeks after modeling, for 4 weeks. They were measured with pH of joint fluid, observed structure and pathology of cartilage under transmission electron microscope, detected apoptosis index, and determined the expression of acid-sensing ion channel 1 (ASIC1), p38 mitogen-activated protein kinases (p38MAPK) and p53 with Western blotting, and distribution of ASIC1 with immunohistochemistry in cartilage tissue. Re-sults The pHs of joint fluid from high to low were ranged as the groups A=C>D>B (P<0.01). The cartilage structure was more complete in the groups A, C and D than in the group B. The apoptosis rates from less to more were ranged as the groups A=C

Objective: To explore aspirin resistance (AR) phenomenon in patients with coronary artery disease (CAD) for secondary prevention and to study the relationships between AR and COX1, COX2, TBXA2R gene polymorphisms. Methods: A total of 2881 CAD patients taken aspirin (100 mg/day) in 7 consecutive days were enrolled. Among them, 2 groups were established as AR group, n=166 and Control group, n=200 aspirin sensitive patients. Platelet aggregation function was induced by arachidonic acid (AA), COX1, COX2 and TBXA2R gene polymorphisms were examined by polymerase chain reaction-restricted fragment length polymorphisms (PCR-RFLP) method. Results: The occurrence rate of AR was 5.76% (166/2881). There were 8 tagSNPs locus in 3 genes as in COX1:(rs3842788), (rs4273915), (rs7866582); in: COX2 (rs3218625); in TBXA2R: (rs2238630), (rs2238631), (rs2238633), (rs3786989). The frequencies of wild type, heterozygous genotype and homozygous genotype were similar between 2 groups. Conclusion: The incidence rate of AR is not high in CHD patients with regular aspirin medication; single nucleotide gene polymorphisms of COX1, COX2 and TBXA2R have no obvious correlation to AR.
