OBJECTIVETo study the inhibition of maxizyme (Mz) directed against the mutant-type p53 gene (mtp53) at codon 249 in exon 7 (AGG --> AGT) both in cell-free system and in MHCC97 cell lines.

METHODSMaxizyme and control mutant maxizyme (G5 --> A5) were designed by computer and cloned into the eukaryotic expression vector pBSKneoU6 (pU6Mz, pU6asMz). Mz was driven by T7 RNA polymerase promoter in vitro. In the cell lines, U6 promoter was driven by RNA PolIII. The mutant type p53 gene fragment was cloned into the pGEM-T vector under the T7 promoter control. The 32P-labeled mtp53 transcript was the target RNA. Cold maxizyme transcripts were incubated with 32P-labeled target RNA in vitro. pU6Mz was introduced into MHCC97 cells by Lipofectamine2000 and mtp53 expression was analyzed by RT-PCR and Western blot.

RESULTSIn vitro cleavage showed that pU6Mz was very active with cleavage efficiency of 42% while pU6asMz was not. The wild type p53 was not cleaved. Partial down-regulation of mtp53 mRNA and mtp53 protein were observed in MHCC97 cells transfected with pU6Mz but not those with pU6asMz. The proliferation of MHCC cells was inhibited by MTT analysis.

CONCLUSIONOur findings suggest that the chimeric U6 maxizyme against the mtp53 is a new promising gene therapeutic agent in treating hepatocellular carcinoma.

OBJECTIVETo investigate the effect of Lianggesan on the expression of signal transducer and activator of transcription 1 (STAT1) in rats with lipopolysaccharide (LPS)-induced acute lung injury and explore the possible mechanisms of the therapeutic effects.

METHODSEndotoxemia was induced in Wistar rats by intravenous injection of LPS (5 mg/kg). The rats were randomly divided into 6 groups, namely the control group, acute lung injury group (LPS group), 3 Lianggesan groups treated at different doses, and LPS+DEX treatment group. Each group, except for the control group, was further divided into 5 subgroups and examined at 1, 2, 4, 8 and 16 h after LPS injection. Western blotting was used to detect the protein expression of STAT1 and p-STAT1 in the lung tissue.

RESULTSIn LPS group, the expression of STAT1 began to increase at 1 h following LPS injection, reaching the peak level at 4 h; the peak expression of p-STAT1 occurred at 2 h after LPS administration (P<0.01). Compared with LPS group, the 3 Lianggesan groups and DEX group showed significantly decreased expressions of STAT1 and p-STAT1 at 2, 4 and 8 h after LPS injection (P<0.05 or 0.01).

CONCLUSIONAbnormal expression of STAT1 occurs in the lung tissue in the event of ALI. Lianggesan can relieve LPS-induced acute lung injury in rats by decreasing the expression of STAT1 and p-STAT1.

Objective: To analyze the current status of anticoagulant therapy for in-hospital patients with acute coronary syndromes (ACS) at county hospitals of China and to explore the relationship between anticoagulant therapy and clinical outcomes in real medical environment. Methods: 99 county hospitals from15 provinces of China were selected for this prospective registry study and 12373 eligible ACS patients without interventional therapy admitted from 2011-09 to 2014-06 were enrolled. The basic condition, previous history, initial assessment, anticoagulants (unfractionated heparin/low molecular weight heparin) application, severe bleeding events and in-hospital mortality were collected in all patients. Multiple logistic regression analysis was conducted to explore the relationship between anticoagulant therapy and clinical outcomes including in-hospital mortality, severe bleeding events and combined endpoints; meanwhile, possible confounders were adjusted. Results: A total of 9985/12373 ACS patients received anticoagulant therapy and 2388 did not. Anticoagulant therapy was conducted in 92.7% (4237/4570) patients with ST-segment elevation myocardial infarction (STEMI), 90.8% (1639/1805) with non-ST-segment elevation myocardial infarction (NSTEMI) and 68.5% (4109/5998) with unstable angina (UA); there were differences by regions and genders,P<0.01and no difference by age. Multivariable analysis indicated that anticoagulant therapy decreased the risk of in-hospital mortality in ACS patients at 53% (OR= 0.47, 95% CI 0.36-0.62), such reduction in STEMI patients was at 55% (OR=0.45, 95% CI 0.32-0.64), in NSTEMI patients was at 58% (OR=0.42, 95% CI 0.24-0.75); while it had no real effect in UA patients,P>0.05. Meanwhile, it did not increase the risk of severe bleeding events in ACS patients,P>0.05. Conclusion: Anticoagulant therapy has been widely used in STEMI and NSTEMI patients at county hospitals of China and obviously decreased the in-hospital mortality; while the application rate was relatively low in UA patients. The general safety of anticoagulant therapy has been good in ACS patients.

Objective: To understand the gender disparity and influencing factors for in-hospital mortality in patients with ST-segment elevation myocardial infarction (STEMI) at secondary hospitals in China. Methods: A total of 5525 in-hospital STEMI patients from 99 secondary hospitals of 15 provinces or autonomous regions between 2011-09 to 2014-06 were recruited including 1649 female and 3876 male. The in-hospital mortalities were compared between 2 genders and the relevant inlfuencing factors were studied by multiple Logistic regression analysis. Results: There were about 29.8% female and 70.2% male STEMI patients were studied. The in-hospital mortalities in female and male were 13.2% and 5.9%,P<0.01; gender disparity was obviously existing regardless of age, history of MI, hypertension and diabetes mellitus. The mortality in female was higher than male even without diseases history and cardiovascular risk factors. Compared with male gender, female patients were usually having elder age and likely complicated with cardiovascular risk factors; they were with lower incidence to receive ECG, drug therapy and thrombolysis within 10 minutes of admission. With adjusted confounding factors, multiple regression analysis presented that female STEMI patients had the higher mortality than male (OR:1.7, 95% CI:1.4-2.0). Conclusion: The in-hospital mortality for STEMI patients was higher in female than male at secondary hospitals in China. Female patients were usually having elder age, complicated with more cardiovascular risk factors, while with less chances to receive ECG, drug therapy and thrombolysis within 10 minutes of admission.
