Objective To analyze the efficacy and tolerance of methotrexate(MTX)in remission maintenance of Crohn′s disease (CD).Methods From June 2012 to August 2015 ,49 CD patients who received MTX as mainly treatment medication to maintain remission were enrolled.The pre-medication history,efficacy,dosage and side effects of MTX were analyzed.The effects of inducing strategy on disease recurrence were analyzed.Chi-square test and t test were used for statistical analysis.Results Among the 49 patients,34 (69.4%)received steroids for remission inducing,nine (18.4%)received infliximab for remission inducing and six (12.2%)achieved remission after operation.In the 44 patients treated with azathioprine (AZA)before,the median treatment time was one month and the dosage for withdrawal of AZA was (42.0 ± 14.8)mg/d.The most common reason was leucopenia (81 .8%, 36/44).Till the time point of follow-up,46 of the 49 CD patients still took MTX orally with a median treatment time of 16 months,and the weekly dosage was (12.7 ±2.0)mg.Thirty-one cases (67.4%) achieved clinical stability,while 15 cases (32.6%)underwent clinical recurrence.The median Crohn′s disease activity index (CDAI)was 123.5 ± 66.6.The weekly dosage of clinical stability group was (12.5 ±2.1)mg,and that of clinical recurrence group was (13.0 ±1 .7 )mg,there was no statistically significant difference between the two groups (t =0.802,P =0.426 ).The recurrence rate of steroids-induced remission group was 41 .2% (14/34 ),which was higher than that of infliximab and surgery-induced remission group (1/15),and the differnce was statistically significant (χ2 =5 .177,P =0.023 ). The common side effects were gastrointestinal reaction (26.5 %, 13/49 ), impaired liver function (20.4%,10/49)and leukopenia (12.2%,6/49).Only three cases could not tolerate the side effects and underwent medication withdrawal.Conclusions As a second-line immunosuppressant for maintanence remission in CD,MTX is effective and well-tolerated in patients.So it can be an important option during the long course of CD.

To observe the effects of early intervention with effective components from a Chinese herbal formula (Huannao Yicong formula, HNYCF) on behavior and related indicators of cholinergic system in β-amyloid precursor protein (APP) transgenic mice.

This study was aimed to observe different forms of β-amyloid peptide (Aβ) and insulin degrading enzyme (IDE) in the hippocampus and cortex in order to further explore the role of Aβ and IDE on spleen yin deficiency di-abetes-associated cognitive decline (DACD), and the effect of Zi-Bu Pi-Y in method. The rats were randomly divided into five groups, which were the blank control (Cont) group, diabetes (DM) group, spleen yin deficiency (pi) group, spleen yin deficiency diabetes (piDM) group and Zi-Bu Pi-Y in recipe (ZBPYR) group. Soluble and insoluble Aβ in the hippocampus and cortex of rats were extracted by gradient centrifugation, and then measured by ELISA. The ex-pression of IDE was observed by western blot. The results showed that the content of soluble and insoluble Aβ1-42 in the hippocampus and cortex of the DM group and piDM group were higher than the Cont group. The soluble and in-soluble Aβ1-42 content in the hippocampus and cortex of the ZBPYR group were reduced compared with the DM group and the piDM group. The soluble Aβ1-40 in the cortex of the DM group, pi group and piDM group were in-creased compared with the Cont group (P < 0.05). The soluble Aβ1-40 content of the ZBPYR group was decreased compared with the DM group and the piDM group (P < 0.05). The expression of IDE protein was decreased in the hippocampus of the DM group and the piDM group compared with the Cont group (P< 0.05), and the IDE protein level in the hippocampus of the ZBPYR group was increased compared with the DM group and the piDM group (P<0.05). The expression of IDE protein in the cortex of the DM group, pi group and piDM group was lower than the Cont group (P< 0.05). The IDE protein level in the cortex of the ZBPYR group was reduced compared to the DM group (P< 0.05). It was concluded that the increased Aβ1-42 in brain may be a major pathological change of DACD and spleen yin deficiency DACD. The decreased IDE expression may be one of the reasons to induce increasing of Aβ1-42 level. The Zi-Bu Pi-Y in method may decrease the Aβ1-42 content by upregulating IDE protein expression.

OBJECTIVETo investigate the relationship between hormone sensitive lipase (HSL) gene polymorphism and aerobic endurance.

METHODSThe (CA)n repeats polymorphism genotypes in HSL intro 6 of 123 outstanding long distance runners and 127 controls of Han nationality in northern China were analyzed by PCR and Fluorescence labeled STR-genescan. Repeat polymorphisms were grouped according to segmentation point and alleles were divided into long or short chains. Chi-square test was used to analyze the frequency difference of allelic and genotypic between athlete and control groups.

RESULTS(CA) n repeats polymorphism in HSL gene was total of 9 different repeat number of alleles, which composed of 25 different genotypes. The chi-square test result showed that when compared short and long chain alleles split by 4, there was a significant difference (P <0.05) of genotype distribution in 5/10 km group compared with control. Compared the rest groups with control, there was no significant difference.

CONCLUSIONCompared short and long chain alleles split by 4, the LL genotype of (CA)n of HSL was associated with aerobic endurance and it might be a molecular marker of elite 5/10 km long distance runners.
