Objective To investigate the role of transcription factor Ets-1 involved in premature rupture of membranes(PROM) by detecting its expression and location in human fetal membranes. Methods Between Feb. and Nov. 2007, 100 pregnant women who delivered in the First Affiliated Hospital, Chongqing Medical University were enrolled in this study. According to gestational weeks, rupture of amuiochorionic membranes and delivery mode, those women were classified into preterm labor group, preterm premature rupture of membranes (PPROM) group, term labor group and term premature rupture of membranes (TPROM) group, matched with elective term cesarean sections women as control group. There were 20 pregnant women in every group. The expression and distribution of Ets-1 protein in fetal membranes were detected by immunohistochemical streptravidin-biotin peroxidase(SP) method and histoscore. In the mean time, 6 cases were chosen from each group randomly and reverse transcription-PCR was used to measure the Ets-1 mRNA expression. Results (1) The expression of Ets-1 mRNA in fetal membranes were 0.342±0.016 in preterm labor group,0.603±0.027 in PPROM group,0.325±0.013 in term labor group, 0.582±0.075 in TPROM group,0.139±0.012 in control group, respectively. When compared with that in control group, Ets-1 mRNA expression were significantly increased in both PPROM and TPROM group(P< 0.05). However, it did not show remarkably difference between preterm group and term labor group, as well as between PPROM and TPROM group (P>0.05). (2) Ets-1 was in stromal layers of amniochorionic membranes and in both cytoplasm and nuclei of trophoblast, which were shown with diffuse intracellular positive granularities (brown-yellow) clearly. No expression of Ets-1 was observed in amniotic epithelial cells. (3) The expression of Ets-1 protein was 0.552±0.018 in preterm labor group, 2.853±0.174 in PPROM group, 0.538±0.042 in term labor group, 2.731±0.090 in TPROM group and 0.214±0.013 in control group, respectively. Ets-1 protein was significantly increased in the stroma of both PPROM and TPROM group than that in control group(P<0.05). However, no remarkable different expression of Ets-1 was observed between preterm and term labor group,so was that between PPROM and TPROM group(P> 0.05). Conclusion Transcription factor Ets-1 is expressed in human amniochorionic membranes and it could be up-regulated in PROM.

Objective To investigate the characteristics of the clinic manifestations and the electromyogram changes in patients with chronic N2hexane intoxication. Methods The clinic manifestations, the electromyography and nerve conduction velocities were analyzed in 9 patients with N2hexane intoxi2 cation. Results The main clinical manifestations of the disease were acroparesthesia and asthenia, especially in legs. The abnormality rate of electromyography in patients with N2hexane intoxication was 100%. The conduction velocity of the sensory nerve and the motor nerve decreased at a rate of 33.33% and 88.89% respectively. The distal latencies were prolonged( 100% ). The denervated electromyogram was 33.33%. Conclusion The main clinical manifestations of the disease were Peripheral neuropathy. The chronic N2hexane intoxication mainly led to the imparement, especially in the distal region of the motor nerve in legs,and the damages of the nerve could be related to the duration of exposure to N2hexane.

With the wide application of Chinese herbal medicine, herb-drug interaction (HDI) has become increasingly prominent. Metabolic enzymes and transporters are the main targets of HDI, because the changes in expression and function of enzymes and transporters can influence the disposition of drugs. Metabolic enzymes are responsible for the metabolic clearance of drugs, including cytochrome P450 (CYP), UDP-glucuronyl transferase (UGT) and sulfotransferases (SULT); transporters widely expressed in the intestine, kidney, liver and brain are involved in the oral absorption, distribution and excretion of drugs. Pueraria, ginkgo, ginseng, St. John's wort and other Chinese herbal medicine often induce a HDI because those herbal medicines combined with chemical medicine are widely used in clinic. The components of herb medicines mentioned above are prone to interact with enzymes and transporters, which often induce a HDI. This paper reviews the advances in the study of enzymes and transporters-mediated pharmacokinetic mechanism of HDI.

Objective To compare analgesic efficacy of intravenous postoperative and preemptive analgesia with flurbiprofen axetil combined with small dose of morphine and with morphine alone. Methods One hundred and twenty patients were randomly divided into four groups: group A,morphine 30 mg +0.9% NaCl for postoperative analgesia,n=30;group B,morphine 20 mg +0.9% NaCl for postoperative analgesia,n=30;group C,flurbiprofen axetil 100 mg + morphine 20 mg +0.9% NaCl for postoperative analgesia,n=30;group D,flurbiprofen axetil 100 mg before operation + morphine 20 mg +0.9% NaCl for postoperative analgesia,n=30.The drugs in each group were diluted to 100 mL and infused by a pump at a rate of 2 mL/h with a patient-controlled analgesia(PCA)bolus of 2 mL after a loading dose of 5 mL.The visual analogue scale(VAS),demanding times for PCA and incidence of side effects were recorded during the period of postoperative 24 h. Results The VAS of group B at 3 h after operation was significantly higher than those of the other three groups(P

Objective To study relationships between myocardial injury and the levels of serum complement C3, C4 and C5b-9 in patients with acute coronary syndrome (ACS). Methods A retrospectively analysis was conducted. 170 ACS patients [including 110 cases of ST-segment elevation myocardial infarction (STEMI) and 60 cases of non-ST-segment elevation acute coronary syndrome (NSTE-ACS)] with ischemic chest pain or chest discomfort onset within the prior 12 hours admitted to the cardiology department of Tianjin Union Medicine Center from January 2014 to July 2016 were enrolled. Thirty-six healthy cases were enrolled as control during the same time. The levels of serum complement C3, C4 and C5b-9 on 1, 3 and 7 days after admission and myocardial function indicators were analyzed. Major adverse cardiovascular events (MACE) and readmission rate were analyzed after 1 year follow-up. The correlation between serum complement levels and myocardial function indicators was analyzed by Pearson correlation analysis. Results ① The levels of serum C3, C4 and C5b-9 on the first day in NSTE-ACS group and STEMI group were significantly higher than control group [C3 (g/L): 1.04±0.33, 1.26±0.35 vs. 0.39±0.21, C4 (g/L): 0.31±0.14, 0.33±0.10 vs. 0.19±0.07, C5b-9 (g/L): 575.46±197.26, 659.26±160.77 vs. 501.40±141.51, all P < 0.05]. There were no changes of serum C3, C4 in NSTE-ACS group, but C5b-9 decreased after a peak (g/L: 700.63±218.42) at 3 days. Serum complements in STEMI group reached peak on the third day [C3 (g/L): 1.37±0.33, C4 (g/L): 0.42±0.12, C5b-9 (g/L): 754.72±136.22]. The levels of serum C4 and C5b-9 in STEMI group were higher than NSTE-ACS group on the third and seventh day. ② The levels of troponin T (TnT), creatine kinase-MB (CK-MB), solution intercellular adhesion molecule-1 (sICAM-1), global registry of acute coronary events (GRACE) scores and percutaneous coronary intervention (PCI) numbers in STEMI group were significantly higher than those in the NSTE-ACS group, which were as opposite as left ventricular ejection fraction (LVEF). However, there were no significant differences in levels of serum N-terminal pro-brain nitric peptide (NT-proBNP), Fibrinogen (Fib), readmission rate and incidence of MACE between STEMI and NSTE-ACS groups. ③ According to GRACE, patients with ACS were divided into low risk group (≤ 108 scores, 26 cases), intermediate risk group (109-140 scores, 61 cases) and highest group (> 140 scores, 83 cases). TnT and sICAM-1 in intermediate risk group were significantly increased as compared with low risk group. Levels of TnT, sICAM-1, C3, C4 and C5b-9 in the highest group were significantly higher than the low and intermediate risk groups, however the lowest LVEF was found in the highest group. ④ It was shown by Pearson correlation analyses that levels of serum C3, C4, C5b-9 were positively correlated with TnT (r value was 0.481, 0.367, 0.292, respectively, all P <0.01), sICAM-1 (r value was 0.298, 0.249, 0.365, respectively, all P < 0.01), but negatively correlated with LVEF (r value was -0.384, -0.260, -0.200, respectively, all P < 0.01). In addition sICAM-1 positively correlated with TnT (r = 0.536, P = 0.000), but negatively correlated with LVEF (r = -0.341, P = 0.001). Conclusions Serum complements activation was found in the acute phase of ACS patients. Serum complement C3, C4 and C5b-9 are involved in the process of myocardial injury, and may reflect severity of myocardial injury and cardiac dysfunction.
