Objective To explore the effect of methylation of peroxisome proliferator-activated receptor γ(PPARy) gene promoter in liver and its mRNA expression changes on decreasing of insulin sensitivity in fetal growth restriction (FGR) rats.Methods Twenty pregnant rats were randomly divided into two groups on their first day of pregnancy:normal-protein group (NP) and low-protein group (LP),ten in each.During pregnancy the LP group rats were fed with low-protein diet (8.00% protein),while the NP group rats were fed with normal-protein diet (20.00% protein).The offspring rats were fed with standard feed after 21 days of birth.Male offsprings in NP group were as control offsprings,and male FGR offsprings in LP group ware as FGR offsprings.At day 3,7,14,30,60 and 90,fasting blood of offsprings was collected to measure fasting plasma glucose (FPG) and fasting insulin(FINS).Then insulin resistance index of homeostasis model assessment (HOMA-IR) and insulin sensitivity index (ISI) were calculated to evaluate insulin sensitivity.At day 7 and 90,liver tissue of male offsprings was collected to extract DNA and total RNA.The methylation level of PPARγ gene promoter and its mRNA expression were detected by methylation specific-polymerase chain reaction (MS-PCR) and reverse transcription-RCR,respectively.The relationships between methylation of PPARγ gene promoter and mRNA expression and insulin sensitivity were analyzed by Pearson correlation and nonparametric test method.Results (1) The mean offspring birth-weight of LP group was (4.92±0.36) g,which was lower than that [(6.43±0.59) g] of control group (t=14.73,P<0.05).In LP group,the incidence of FGR offspring was 88.2% (97/110) and the FGR incidence of male ones was 94.1% (48/51).(2) At day 90,compared with control offsprings,FPG [(8.95±1.83) mmol/L vs (6.21±1.14) mmol/L,t=-3.291,P<0.05],FINS [(59.57±9.89) mU/Lvs (36.10±7.32) mU/L,t=-4.916,P<0.05] and HOMA-IR (0.967±0.297 vs 0.410±0.135,t=-4.472,P<0.05) of FGR offsprings were significantly higher; while ISI of FGR offspring was lower than that of control offsprings (-3.043±0.294 vs -2.172±0.354,t=4.774,P<0.05).(3) There was no significant difference in methylation degree of PPARγ gene promoter in liver between FGR and control offsprings at day 7 (0/8 vs 2/8,Fisher exact test,P>0.05).The methylation degree of PPARγ gene promoter in liver in FGR offsprings was significantly higher than that of control offsprings at day 90 (8/8 vs 2/8,Fisher exact test,P<0.05).Compared with control offsprings,PPARγ gene mRNA expression level of FGR offsprings decreased significantly at day 90 (4.3.07±7.51 vs 146.72± 40.66,t=7.09,P<0.05).mRNA expression of PPARγ gene was the lowest in exhaustive methylation offsprings (27.2± 1.6),and then in partial methylation ones (47.3±33.0),the highest in no methylation ones (144.6 ± 21.2) (P<0.05).(4) The correlation analysis showed that PPARγ mRNA expression level negatively correlated to the level of FPG (r=-0.819),FINS (r=-0.906) and HOMA-IR (r=-0.860),P<0.05 respectively; but positively correlated to ISI level (r=0.947,P<0.05).Conclusions Hypermethylation in promoter region of PPARγ gene might inhibit gene transcription,and be involved in the occurrence of insulin resistance in FGR rats.

The leading cause of drug withdrawal from market and clinical trials failure is drug-induced liver injury (DILI). Varying clinical, histological and laboratory features of DILI, as well as undefined underlying mechanisms, hinder patients to be diagnosed in the early-stage of the disease and receive effective treatments. Conventional indicators, like serum transaminases and bilirubin, have inevitable limitations referring to sensitive prediction and specific detection of DILI. In order to reduce the occurrence of DILI, researchers have attempted to discover potential biomarkers with higher specificity and sensitivity from blood and urine in recent years. This article aims to review recent advances in biomarkers of DILI.

Using MS as basic medium, supplemented with 1.0 mg · L(-1) IBA, the adventitious roots of Tripterygium wilfordii were induced, and the good adventitious root culture system was established by leaves or callus induced by leaves as explants. The adventitious roots were also induced with 2.0-4.0 mg · L(-1) NAA and the good adventitious root culture system established by using suspension cells from callus as materials to induce adventitious root. The content of triptolide of three adventitious roots culture system were exceeded in the natural root bark. The content of triptolide of AR3 adventitious roots was the highest about 5.3 times as that in the natural root bark. By using 5 L stirred fermentor during pilot enlarge cultivation, compared with 250 mL flask cultivation, the adventitious roots increment and secondary metabolites content per liter medium showed no significant difference. The accomplishment of this analysis laid a foundation by tissue culture production of the secondary metabolites of T. wilfordii.

OBJECTIVETo explore the potential effect of Guizhi plus Gegen Decoction (GGD) in improving learning and memory of lipopolysaccharides (LPS) induced neuroinflammatory mice and its possible mechanisms.
METHODSTotally 63 male ICR mice were randomly divided into 5 groups, i.e., the normal control (n = 13), the model group (n = 13), the low dose GGD group (n = 10), the high dose GGD group (n = 14), and the positive control group (n = 13). Mice were intraperitoneally injected with LPS (0.33 mg/kg) to induce Alzheimer's disease (AD) model. Mice in the high and the low dose GGD groups were administered with 12 g/kg or 6 g/kg by gastrogavage for 4 successive weeks. Mice in the control group were intraperitoneally injected with minocycline (50 mg/kg) for 3 days. By the end of treatment LPS were injected 4 h before behavior test each day, and then behavior test was conducted in mice of each group. Effect of GGD on learning and memory of AD mice was observed by using open field test, novel object recognition task, and Morris water maze.
RESULTSOpen field test showed there was no statistical difference in the movement time and the movement distance among all groups (P > 0.05), suggesting that LPS and GGD had no effect on locomotor activities of mice. In novel object recognition test, AD mice spent significantly shorter time to explore novel object after they were induced by LPS (P < 0.05), while for AD mice in the low and high dose GGD groups, their capacities for exploration and memory were significantly improved (P < 0. 05, P < 0.01). Results of Morris water maze showed that AD mice exhibited increased escape latency (P < 0.05) and spent much less time in swimming across the original platform (both P < 0.05). However, AD mice in the low and high dose GGD groups had obvious shortened latency and increased time percentage for swimming (P < 0.05, P < 0.01).
CONCLUSIONGGD possessed certain improvement in learning and memory disorder of LPS induced AD mice.
