Diabetes is seriously hazards to human health and its pathogeneses are not clear. Recent studies show that the imbalance of intestinal flora and the development of diabetes are closely related. Appropriate bacteria can improve blood sugar disorder. Treating diabetes from the theory of Pi-Wei is effective. Regulating intestinal flora has become a new pathway for treating diabetes from the theory of Pi-Wei. On the basis of intestinal flora, authors discussed the treatment of diabetes from Pi and Wei.

Objective To investigate the impact of down-regulation of histone methyltransferase enhancer of zeste homolog 2 (EZH2) on RUNX3 expressions,proliferation and apoptosis in human pancreatic cancer.Methods The expressions of EZH2 and RUNX3 in 38 pancreatic cancer patients and human pancreatic cancer AsPC-1,PANC-1 and BxPC-3 cells were detected by immunohistochemistry and western blot,respectively.Cells were transfected with siEZH2 by lipofectamin 2000.Real time-PCR and western blot were used to detect EZH2 and RUNX3 expressions.Cell growth and apoptosis in vitro and vivo were assessed by MTT,flow cytometry and nude mice experiments,respectively.The correlation among the expressions of EZH2,clinical pathological features and overall survival rate were analyzed.Results Elevated EZH2 and decreased RUNX3 expressions were observed in human pancreatic cancer tissues and cells (P ＜ 0.05).Knockdown of EZH2 reduced cell growth and induced apoptosis in vitro and vivo by upregulating RUNX3 protein expression (P ＜ 0.05).In addition,the EZH2 expressions were correlated with tumor stage,lymph node metastasis and poor prognosis (P ＜ 0.05).Conclusions EZH2 expressions were correlated with malignancy and poor prognosis in pancreatic cancer.Tumor cell proliferation was promoted by EZH2 through down-regulation of RUNX3.EZH2 may be a potential therapeutic target for pancreatic cancer.

To study and compare the protective effects of Cordyceps sinensis from different habitats on acute injury of hepatic tissue induced by carbon tetrachloride ( CCl4 ) . Methods:The rat model of acute injury of hepatic tissue induced by CCl4 was established. The biochemical indicators of alanine aminotranferease ( ALT) and aspartate aminotransferease ( AST) in the serum and superoxide dismutase ( SOD) and L-glutathione( GSH) in the liver tissue were detected, and the liver tissue HE staining was used for the histopathology determination. Results:Compared with those in the model group, the levels of AST and ALT in the serum were sig-nificantly reduced, the levels of SOD and GSH in the liver tissue were notably increased, and the necrosis of liver cells was improved in Cordyceps sinensis groups at low, medium and high dose from different habitats (P<0. 05), however, the differences between the two different habitats were not significant (P>0. 05). Conclusion: Cordyceps sinensis from Qinghai and Tibet shows some positive differences in the protective effect on the acute chemical liver injury induced by CCl4 in rats,however, the differences are not remarka-ble.

Antimicrobial peptides are a class of small peptides with anti-extrogenous pathogen activities.They are derived from organism and possess antibacterial,antifungus,antiviruses and anticancer cell actions.In recent years,it’s found that some microbial pathogens are able to resist antimicrobial peptides.The constitutive and inducible mechanism of a pathogen resists a given peptide were reviewed in this paper.

Objective Supramolecular hydrogels were the hydrogels consisting of a solid 3D network with noncovalent bonds.Its unique properties such as biocompatibility,biodegradability,free sol-gel transformation and stable drug release ability make it widely exploited for various biomedical applications.This paper mainly focused on the use of supramolecular hydrogels in all types of biomedical application such as biosensor,cell culture,tissue engineering,gene engineering and drug delivery by research literature reviews.They hope that this focus review will contribute topromote the use of supramolecular hydrogels.

Sphingosine kinase 1 (SphK1) plays critical roles in cell biological functions. Here we investigated the effects of SphK1 inhibitor SKI II on hepatoma HepG2 cell cycle progression and invasion. Cell survival was determined by SRB assay, cell cycle progression was assayed by flow cytometry, the ability of cell invasion was measured by Matrigel-Transwell assay and protein expression was detected by Western blotting. The results showed that SKI II markedly inhibited HepG2 cell survival in a dose-dependent manner, induced G1 phase arrest in HepG2 cell and inhibited cell invasion. SKI II markedly decreased the expressions of G1-phase-related proteins CDK2, CDK4 and Cdc2 and the levels of cell invasion-associated proteins MMP2 and MMP9. The results showed that SKI II inhibited cell cycle progression and cell invasion, implying SphK1 as a potential target for hepatoma treatment.

Objective:To investigate the whole genome characteristics of coxsackievirus A4 (CVA4) circulating in Qingdao city.Methods:Four CVA4 isolates circulating in Qingdao city during 2013 to 2015 were selected. Whole genome sequences of these strains were amplified by one-step reverse transcription-polymerase chain reaction (RT-PCR). Sequence alignment and phylogenetic analysis were performed using MEGA7.0 software package. Genetic recombination analysis was performed using similarity plots 3.5.1 software package.Results:Phylogenetic analysis showed that based on the sequences of the whole genome and P1, P2 and P3 regions, HS312/QD/CHN/2013 and HS605/QD/CHN/2014 strains together with the early domestic isolates belonged to the same clade, while FY218/QD/CHN/2015 strain and CV-A4/P1033/2013/China strain collected in Wenzhou in 2013 formed another clade in each phylogenetic tree. HS144/QD/CHN/2014 strain belonged to the same clade as HS312/QD/CHN/2014, HS605/QD/CHN/2014 and the early domestic CVA4 isolates in the phylogenetic tree based on the P1 region, but formed a separate clade in the phylogenetic trees based on the whole genome, P2 region and P3 region. Genetic recombination analysis revealed that there was genetic recombination between HS144/QD/CHN/2014 strain and the CVA2 strain of CV-A2/P373/2013/China isolated in mainland China in 2013 in the region of 2C-3D (5 081-7 301); FY218/QD/CHN/2015 and CV-A4/P1033/2013/China strains were highly homologous and recombination signal sequences were detected in the region of 2A-2B (3 821-4 161) between the two strains and the CVA2 strain of CV-A2/P373/2013/China.Conclusions:The CVA4 isolates circulating in Qingdao city presented obvious genetic diversity at the genome-wide level.

OBJECTIVETo study the constituents with the pain-relieving activity from the stem rind of Daphne giraldii.

METHODThe partition of the ethanol extract and chromatographic separation of the fractions were carried out by the monitoring of anelgesic pharmacological activity. The structures of the isolated compounds were determined by MS and NMR.

RESULTFour compounds were isolated from the pain-relieving fraction. Three of them were identified as diterpenes, gniditrin (1), gnidicin (2) and daphnetoxin (3). Compound 4 was determined as Z-octadecyl caffeate.

CONCLUSIONCompounds 1, 2 and 4 were isolated from the plant for the first time.
