This study was aimed to explore five Chinese medicine components or ingredients from Qu-Shi Hua-Y u Decoction (QSHYD) with uniform design method and screen ingredients assembling of Chinese medicine BZL pre-scription in order to verify its therapeutic effect on experimental fatty liver rats. High-fat diet was used in the estab-lishment of fatty liver rat models. Five effective ingredients (i.e., chlorogenic acid, geniposide, curcumin, polydatin and polysaccharide of Atractylodes macrocephala Koidz) of QSHYD were used as study subjects. Uniform design was applied in the grouping design. The intragastric administration was given for four weeks. The screening index was the content of liver triglyceride (TG). The ingredients assembling of Chinese medicine BZL prescription was screened through uniform design and regression analysis. The same fatty liver animal model was used in the comparison be-tween QSHYD and rosiglitazone. The TG content in liver tissues of rats and serum ALT activity were detected. The pathological changes of liver tissues were observed (HE stain and oil red O stain) with Ridit analysis to verify its therapeutic effect. The results showed that through screening, the regression equation was Y = 15.083X1 + 5.321X2- 5.186X3 - 16.157X4 + 9.35X5 + 17.667X3X4 - 8.422X1X2 - 6.617X3X5 + 16.571 (X1: chlorogenic acid, X2:polydatin, X3: polysaccharide of Atractylodes macrocephala Koidz, X4: geniposide, X5: curcumin). According to this equation, the best TG reducing effect occurred when the chlorogenic acid (X1), polysaccharide of Atractylodes macrocephala Koidz (X3), and geniposide (X4) were the maximum dosage. It showed that the best combination in inhibiting TG content in liver tissues was X3, X4 and X1 (i.e. BLZ prescription). Among fatty liver rat mod-els induced with same high-fat diet, the screened Chinese medicine ingredient BZL prescription can obviously reduce its TG content in liver tissues and serum ALT activity ( P < 0 . 01 ) . It obviously improved the fatty degen-eration of rat's liver. It was concluded that ingredients assembling of Chinese medicine BZL prescription screened through uniform design can obviously prevent and treat fat deposition and injury of the liver among rat models induced by high-fat diet .

The specific fragment of Pneumococcal surface protein A(PspA)and Pneumococcal Surface Adhesin A(PsaA)gene was amplified by PCR from Streptococcus pneumonia 5 and Streptococcus pneumonia 19.The amplified fragnent of PspA and PsaA gene was ligated into pET-27b(+)vector and transformed into BL 21 E.coli for expression and obtain the expressive production of PspA and PsaA.Induced by IPTG,the expression level was as high as 75 % of the total disolube protein.The result showed that the recombinant plasmid could express a specific 75 kDa and 37 kDa fusion protein in E.coli BL 21,which showed the good immunogenicity and a broadly cross reactivity with the other serotypes.

Background:Glioblastoma is one of the most common malignant brain tumors.Conventional clinical treatment of glioblastoma is not sufficient,and the molecular mechanism underlying the initiation and development of this disease remains unclear.Our study aimed to explore the expression and function of miR-873a-5p in glioblastoma and related molecular mechanism.Methods:We analyzed the most dysregulated microRNAs from the Gene Expression Omnibus (GEO) database and examined the expression of miR-873-5p in 20 glioblastoma tissues compared with ten normal brain tissues collected in the Zhejiang Tongde Hospital.We then overexpressed or inhibited miR-873-5p expression in U87 glioblastoma cell lines and analyzed the phenotype using the cell counting kit-8 assay,wound healing assay,and apoptosis.In addition,we predicted upstream and downstream genes of miR-873-5p in glioblastoma using bioinformatics analysis and tested our hypothesis in U87 cells using the luciferase reporter gene assay and Western blotting assay.The differences between two groups were analyzed by Student's t test.The Kruskal-Wallis test was used for the comparison of multiple groups.A P ＜ 0.05 was considered to be significant.Results:The miR-873-5p was downregulated in glioblastoma tissues compared with that in normal brain tissues (normal vs.tumor,0.762 ± 0.231 vs.0.378 ± 0.114,t =4.540,P ＜ 0.01).Overexpression of miR-873-5p inhibited cell growth (t =6.095,P ＜ 0.01) and migration (t=3.142,P ＜ 0.01) and promoted cell apoptosis (t=4.861,P ＜ 0.01),while inhibition of miR-873-5p had the opposite effect.Mechanistically,the long non-coding RNA HOTAIRM1 was found to act as a sponge of miR-873-5p to activate ZEB2 expression in U87 cells.Conclusions:We uncovered a novel HOTAIRM1/miR-873-5p/ZEB2 axis in glioblastoma cells,providing new insight into glioblastoma progression and a theoretical basis for the treatment of glioblastoma.

OBJECTIVETo observe the effect of CKJ Recipe (consisting of Cordyceps sinensis polysaccharide, amygdaloside, and gypenosides) containing serum on the activation of rat primary hepatic stellate cells (rHSCs) and to explore its pharmacological mechanism.

METHODSrHSCs were isolated form liver and cultured for four days. Then they were divided into the normal control group, the model group, and the CKJ group. rHSCs in the model group and the CKJ group were treated with 2.5 ng/mL transforming growth factor beta1 (TGF-beta1) in serum-free DMEM for 24 h. Serum free DMEM (containing no TGF-beta1) was taken as the control for the normal control group. rHSCs in the CKJ group were treated with 5% CKJ-containing serum for 24 h. rHSCs in the other two groups were treated with 5% blank serum for 24 h.The protein expression level of a smooth muscle actin (alpha-SMA) was determined using high throughput screening (HCS) and Western blot. mRNA expression levels of alpha-SMA, collagen I (Col-I), platelet-derived growth factor receptor beta (PDGF-betaR), TGF-beta1, transforming growth factor beta receptor 1 (TGF-betaR1), and transforming growth factor beta receptor 2 (TGF-beta R2) were detected using quantitative RT-PCR.

RESULTSCompared with the normal control group, the protein expression level of alpha-SMA, mRNA expression levels of alpha-SMA, Col-I, PDGF-betaR, TGF-beta1, TGF-betaR1, and TGF-betaR2 significantly increased in the model group (P<0.05, P<0.01). Compared with the model group, the protein expression level of alpha-SMA, mRNA expression levels of alpha-SMA, Col-I, PDGF-betaR, TGF-beta1, TGF-beta1, and TGF-beta R2 significantly decreased in the CKJ group (P<0.05, P<0.01).

CONCLUSIONCKJ containing serum could inhibit the protein expression level of o-SMA, which was probably related with inhibiting TGF-beta1 and its related receptors.
