AIMTo study the mechanism of butylated hydroxyanisole-induced neural differentiation of fetal liver cells in vitro.

METHODS14.5-day-old mouse fetal liver-derived cells were cultured, and were induced by 200 micromol/L butylated hydroxyanisole (BHA) combined with PI3K inhibitor LY294002 (20 micromol/L), and then were incubated in serum-free medium. Expression of genes in treated or untreated cells were assayed by Western blotting or RT-PCR.

RESULTSThere was low level of neurofilament-L (NF-L) and brain factor-1 (BF-1) but no neurofilament-H (NF-H) and tyrosine hydroxylase (TH) in fetal liver cells. BHA promoted significantly expression of neuron-specific NF-L, NF-H, BF-1, and TH in fetal liver cells. NF-L mRNA increased 5.8 fold, NF-H mRNA 8.0 fold, BF-1 mRNA 2.68 fold, and TH mRNA 30 fold, respectively (all P < 0.01 vs untreated cells). NF-L protein increased 11.29 fold, NF-H 5.5 fold, BF-1 2.53 fold, TH 4.76 fold. Moreover, expression of these BHA-induced genes were inhibited by PI3K inhibitor LY294002.

CONCLUSIONBHA induced neural differentiation of fetal liver cells through PI3K.

OBJECTIVETo compare therapeutic effects of herb-partitioned spread moxibustion and western medicine on chronic nonspecific ulcerative colitis.

METHODSSixty cases were randomly divided into a spread moxibustion group (n = 28) and a western medicine group (n = 32). The spread moxibustion group was treated with herb-partitioned spread moxibustion at lower limb around stomach meridian, abdomen region around Guanyuan (CV 4) and lower Jiaji (EX B 2) points; and the western medicine group was treated with oral administration of Sulfasalazine. Their therapeutic effects were observed after treatment.

RESULTSThe cured-markedly effective rate was 71.4% (20/ 28) in the spread moxibustion group, and 25.0% (8/32) in the western medicine group, the former was better than the latter (P < 0.05).

CONCLUSIONSThe therapeutic effect of herb-partitioned spread moxibustion for treatment of chronic nonspecific ulcerative colitis is better than that of the oral administration of Sulfasalazine with less adverse reaction, and is worth popularizing in clinic.

Objective To evaluate the safety of dabigatran etexilate in the anticoagulant therapy.Methods The randomized controlled trials about dabigatran etexilate in the treatment of all kinds of embolism disea-ses, which had been published from the time of library foundation to June, 2015 were collected from PubMed, ClinicalTrials.gov, CNKI data-base according to the following criterias.An the same time results of studies were analyzed through using Stata 13.1 software and Rev Man 5.3 software.Results Sixteen randomized controlled trials were includ-ed, involving 42395 patients.Meta -analysis showed that dabigatran etexilate could significantly reduce the incidence of major bleeding com-paring with comparators ( P<0.05 ) , especially compared with warfarin ( P<0.01 ) .However the incidence of major bleeding with dabigatran etexilate was similar to comparators when the dosage was increased. Moreover dabigatran etexilate could significantly increase the risk of myo-cardial infarction ( P <0.01 ) , especially compared with warfarin (P<0.01).while the incidence of myocardial infarction with dabigatran etexilate was increased with the increase of the dosage.In addition dabig-atran etexilate could significantly increase the incidence of gastrointestinal bleeding ( P <0.01 ) , especially compared with warfarin and placebo ( P<0.05) , which was dose-dependent.There was no publication bias in funnel plots and sensitivity analysis indicated the results were reliable. Conclusion The use of dabigatran etexilate was associated with a significant increase in the risk of myocardial infarc-tion and gastrointestinal bleeding.Therefore, clinicians need to take these risks into account in treatment.

BACKGROUNDStathmin was identified as an endometriosis-related protein by comparative proteomics in our previous study. As a microtubule-destabilizing factor, stathmin was shown to participate in the relay and integration of diverse intracellular signaling pathways involved in cell proliferation, differentiation, and many other cellular activities. To investigate whether stathmin is involved in the pathogenesis of endometriosis, we examined the expression of stathmin in eutopic endometrium of women with or without endometriosis.

METHODSEutopic endometrium samples were collected from thirty-six patients who were diagnosed as endometriosis and the nineteen age-matched patients who were confirmed to be free of endometriosis surgically and histologically. The expression of stathmin mRNA was detected by real-time PCR, and its protein was detected by Western blotting and immunohistochemistry.

RESULTSStathmin was overexpressed in eutopic endometrium of women with endometriosis detected by real-time PCR in mRNA levels and by Western blotting in protein levels, without significant difference between proliferative and secretory phase. Immunohistochemistry showed that stathmin protein was localized in both endometrial glandular and stromal cells throughout the menstrual cycle.

CONCLUSIONSStathmin is overexpressed in endometrium of patients with endometriosis and may play a role in the pathogenesis of endometriosis.

OBJECTIVETo isolate, culture and identify a dog periodontal ligament stem cells (PDLSC) line in vitro.

METHODSThe adult dog periodontal ligament cells were isolated by limited dilution of culture cell for single cell clone. Cells originated from one of these clones were assessed through colony-forming efficiency and immunocytochemistry assay and alkaline phosphatase stain was used to identify the source of adult dog periodontal stem cells, at the same time, PDLSC were induced with mineralizatin solution and was found to have long protrude like an osteoblast. Differentiation of PDLSC were assessed. Mineralized potential was studied by Von-Kossa staining.

RESULTSThe dog PDLSC expressed STRO-1, which was the marker of mesenchymal stem cells. Also Vimentin, osteoblast-like marker alkaline phosphatase and Collagen-I expressed weakly. Cells were clonegenic, highly proliferative cells and capable of differentiating into osteoblasts/cementoblasts.

CONCLUSIONThe evidence suggests that the cultured cells were stem cells from adult dog periodontal ligament.

OBJECTIVETo observe the position and quantity of nestin expression in SD rat eyes in different stages of postnatal development.

METHODSImmunocytochemical method was used to identify nestin expression in the eyes of SD rats of 1 to 30 days old.

RESULTSNestin expression was detected in the retina and extraocular muscles of SD rats. The expression varied with the time of postnatal development, distributing in the entire retina layers in earlier stages and confined in the nerve fiber layer in later stages. The quantities of nestin expression in the extraocular muscles decreased gradually with growth.

CONCLUSIONNestin expression in the retinas and extraocular muscles of SD rats decreases during the postnatal development.

Encephalomyocarditis virus (EMCV) is a natural epidemic zoonotic pathogen. However, no reports have been published regarding the isolation, identification and full-length genome of EMCV from a local aardvark population. In present study, an EMCV isolate HNXX13 was isolated from aardvarks named Huainan-pig in Henan Province. The systematic identification, full-length genome sequencing and molecular characteristic analysis of the isolate HNXX13 were conducted. The result showed that the isolate was spherical with a diameter of 24-30 nm, neither heat- nor acid-resistant, sensitive to trypsin, insensitive to chloroform, not protected by bivalent cationic, and the specific fluorescence was observed in the cytoplasm of BHK-21 cells infected with the isolate by using indirect fluorescence assay. The full-length genome of EMCV HNXX13 generated a 7 725bp sequence (GenBank: F771002), with 81.0%-99.9% nucleotide identity to reference strains from different animals, and 99.5% with a Chinese reference strain isolated earlier from a commercial pig herd. The phylogenetic tree based on the full-length genome and ORF sequences identified that all EMCV strains were divided into three groups G1, G2 and G3, and strain HNXX13 belonging to the G1 group with other Chinese reference strains. The result also identified that this EMCV infection could cause severe clinical signs in a local aardvark population, and enriches the molecular epidemiological data of EMCV in China. Regional differences exist in EMCV genome and transmission is limited within a certain area. However, the cross-infection and transmission of EMCV between aardvark and mice appears most likely. Mutations have occurred in some amino acids of EMCV strain HNXX13 during the transmission in local aardvark herd and these mutations might make the virus easier to infect the aardvark.

OBJECTIVETo improve the accuracy and sensitivity of cell membrane chromatography (CMC) and evaluate the feasibility of CMC in the study of subtype receptors.

METHODSPlasmids were used to transfer alpha(1B)-AR cDNA into human embryonic kidney 293 (HEK293) cell lines to obtain cell lines stably overexpressing the subtype receptors. HEK293 alpha(1B) cell membrane stationary phase (CMSP) was prepared by immobilizing the cell membrane on silica. The retention time of 9 alpha(1)-adrenoceptor ligands and capacity factors(kappa'(HEK293 alpha1B)) were calculated. The capacity factors of rat liver tissue and primary cultured rat hepatocytes were also calculated for a correlation analysis.

RESULTSThe calculated capacity factors (kappa') were positively correlated to the published pKi values. The affinity rank orders were identical. The longest retention of the 9 alpha(1)-adrenoceptor ligands occurred on CMSP prepared with HEK293 alpha(1B) cell lines, while CMSP obtained from rat liver tissue showed the shortest retention of the ligands.

CONCLUSIONCMC proves practical in the study of the subtype adrenoceptors. The accuracy and sensitivity of CMC can be improved using HEK293 alpha(1B) cell membrane.
