Objective To explore the environmental risk factors,periconceptional folate intake and methylenetetrahydrofolate reduetase(MTHFR) gene C667T polymorphism of pregnant women on congenital heart diseases(CHD) in offspring.Methods Retrospective case-control study was carried out to investigate periconceptional folate supplementation and environmental factors in 98 parents with CHD offsprings and 101 parents with normal offsprings.The mothers'MTHFR gene C667T mutation was also identified.The possible risk factors were analyzed by simple and multiple factors Logistic regression methods.Results Six factors were related to the occurrence of CHD in the offspring:education of gestation mother,no prenatal examination,under depressed or nervous condition during pregnancy and maternal exposures to harmful substance;periconceptional folate and compound vitamin supplementation were protection factors.There were significant difference between case and control group in folate supplement(P

microRNAs ( miRNAs) are a family of short non-cod-ing RNAs that regulate the expression of target genes by binding to complementary regions. The miRNAs expression is readily al-tered by drugs, carcinogens, hormones, stress or diseases, and that might lead to changes in the drug metabolism, pharmacoki-netics or potency. Moreover, the evaluation of drug metabolic enzyme-related miRNAs would provide useful information for per-sonalized medicine. This review describes the current knowledge on the post-transcription regulation of drug metabolic enzymes by miRNAs.

Objective To observe two main subtypes of MAPK family-ERK and JNK activation in HSCs and investigate the effects of the serum of Radix Salviae Militiorrhizae treated animals on the activation of ERK and JNK in HSCs. Methods HSCs were cultured in vitro. After the model of hepatic fibrosis was replicated in SD rats, Radix Salviae Militiorrhizae decoction was given via gastrogavage to the rats of treatment groups to obtain serum containing the drug. The dose was 10 times of dose per kg per day for adults in 2 divided doses for 6 consecutive days, while the same volume of 0.9% NaCl was given to the rats of non-treatment groups. on the 7th day, the routine dose was orally given again; the blood sample was drawn from the vena cava after 2 hour; the serum was isolated and inactivated with water bath at 56℃; finally, the serum was filtered to eliminate bacteria. Just before using the serum, RPMI-1640 culture medium was added to prepare culture media of 10% drug-containing serum, which was incubated with the subcultured HSCs. The experiment was divided into the following groups: A: serum of extracted from normal rats; B: medicated serum of RSM extracted from normal rats; C: serum from CCl_4-induced liver fibrosis rats; D: medicated serum of RSM extracted from CCl_4-induced liver fibrosis rats.After 24h incubation with above every group serum which were added blindly to HSCs, P-ERK and P-JNK were detected by Western blot respectively. Results Both RSM Pharmacological serums decreased P-ERK and P-JNK in HSCs significantly compared with controls (P

Objective To probe into impacts of safflor yellow injection on rats with acute myocardial infarction and discuss its mechanism. Methods Forty Sprague-Dawley rats were divided into sham operation group ( 8 rats ) and operation groups(32 rats).The left anterior descending branch of coronary artery was ligated to establish an animal model with acute myocardial infarction.The rats with successful modeling were randomly divided into model control group, 3-, 7- and 14-days safflor yellow group.In the treatment group, the rats were injected with safflor yellow injection(2.5 mg.kg-1.d-1)for 3, 7 and 14 days, respectively.Rats in sham operation and model control group were injected 0.9% sodium chloride solution.Their weights were measured 24 h after the last drug administration, their hearts were removed, and the serum was obtained through centrifugation.The enzymic method was used to measure the lactate dehydrogenase(LDH)and creatine kinase(CK)contents of serum.Hematoxylin eosiny(HE)staining method was used to observe the change of myocardial cells.The chloride three phenyl-tetrazole( TTC) staining method was used to measure the area of myocardial infarction in the rats. The real-time fluorescent quantitative PCR method was used to measure the expression of VEGF and HIF mRNA at the marginal zone of myocardial infarction. Results The levels of LDH and CK were(106.12±35.52),(452.84±60.38)mmol.L-1 in sham operation group, and(385.66±137.58),(2 111.00±1 250.80)mmol.L-1 in model control group.LDH in 3-, 7-, 14-days treatment groups was (249.66±51.86),(104.33±51.08),(110.33±26.76)mmol.L-1, while CK was(1 713.00±584.74),(1 177.66±980.18), (421.33±54.60)mmol.L-1.LDH and CK levels of the 14-days treatment group were significantly lower than those in the model control group(both P<0.05).The area of myocardial infarction was (0.00±0.00)% in sham operation group,(13.12±6.69)% in the model control group, and(8.11±3.45)%,(7.01±2.98)%,(3.44±1.17)% in the 3-, 7-, 14-days treatment groups.The area of myocardial infarction in the 14-days treatment group was significantly lower than that of the model control group(P<0.05).The expression of VEGF and HIF mRNA was 1.99±0.27, 6.21±1.35 in the sham operation group, 1.03±0.15, 1.78±0.57 in the model control group.The expression of HIF mRNA in the 3-, 7-, 14-days treatment groups was 0.50±0.12, 1.23±0.24, 2.20± 0.32, and the expression of VEGF mRNA in the 3-, 7-, 14-days treatment groups was 0.43±1.27, 2.67±0.83, 5.78±1.23. Conclusion The safflor yellow injection has therapeutical effects on the rats with acute myocardial infarction, and the effects will become significant after 14 day.It can reduce the area of myocardial infarction and LDH and CK content at the drug administration groups, which might be related to the increase of the expression of VEGF and HIF mRNA.
