Objective To study the relationship between Nogo-B and transforming growth factor-β1 (TGF-β1)/Smad2 signaling pathway in mice models of hepatic fibrosis.Methods Twenty four healthy male ICR mice were divided into two groups,with 6 in the control group and 18 in the model group.Mice in the model group were further divided into three subgroups according to different time points:subgroups of 4,8 and 12 weeks,with 6 mice in each subgroup.Hepatic fibrosis of mice was induced by subcutaneous injection of carbon tetrachloride (CCl4).The histopathologic changes of the liver were observed by optical microscope using hematoxylin-eosin and Masson trichrome stainings of the liver tissues.Expressions of Nogo-B,Smad2 and TGF-β1 mRNA and proteins in liver were detected by reverse transcription-polymerase chain reaction (RT-PCR),Western blot and immunohistochemistry assays,respectively.Means among groups were compared by univariate analysis of variance.Results The hepatic fibrosis models were successfully induced by CCl4 injection.The expressions of two subtypes of Nogo-B,Nogo-B1 and Nogo-B2 mRNA in normal livers were 0.140±0.050 and 0.104±0.023,but both significantly increased in the livers of mice in the 12 week model subgroup (1.054±0.040 and 0.500±0.057,F=431.41 and 135.46,respectively; both P<0.01).The Nogo-B protein was mainly expressed in nonparenchymal cells of the liver,and was hardly expressed in hepatocytes.Linear correlation analysis showed that the expressions of Nogo-B mRNA and proteins were positively correlated with Smad2 and TGF-β1 mRNA and proteins (all P<0.01),which were considered to participate in the signaling pathway of hepatic fibrosis.Conclusion Nogo-B might play a role in the development and progression of hepatic fibrosis by participating in TGF-β1/Smad2 signaling pathway.

Objective To analyze a population of cells on the right lower lateral of monocyte population in forward scatter/side scatter(FSC/SSC)(X-axis/Y-axis)scatterplot of peripheral blood leucocyte by flow cytometry(FCM)and its influencing factors.Methods The type of cells were identified based on cluster of differentiation antigen(CD)by FCM.The impact of temperature,hemolysin concentration,and incubation time was evaluated.Blood lipid tests were performed to observe the relation between them by statistical methods.Results (1) Phenotypo of this population of cells on the right lower lateral of monocytes in FSc/SSC scatterplot is CD+45 CD+13 CD+14 CD3- CD-19 ,which was the same as monocyte cells:(2)The monocytes in FSC/SSC scatterplot shifted to left side after using haemolysin;(3)The monocytes showed less resistance to antihemolysin in 37℃ than that in 220C:There were more monocytes shifting to left side with the increase of haemolysis time:(4)The swarming ratio of monocytes in patients (31.5%,40/126) Was higher than it in normal controls (5.1%,5/98)(x2=22.74,P<0.01);(5)The levels of total serum cholesterol(TC),triglyeride(TG),low density lipoprotein cholesterol(LDL-C), apoprotein B100(Apo B100) in patients with swarming monocytes were lower than that in the patients without swarming monocytes,(P<0.05).There was no statistical significance between the two groups with respect to levels of total bilirubin(TBIL),albumin(Alb),hish density lipoprotein cholesterol(HDL-C),apoprotein A I(Apo A I),lipoprotein(Lpa).Conclusions Peripheral blood monocytes can be divided in two groups in FSC/SSC scatterplot when analyzed with FCM.The presence of this population of cell Was related to resistance to hemolysin.It can be influenced by haemolysis time and incubation temperature.Therefore,the effect of swarming monocytes and abnormal cell membrane should be taken into consideration when the markers and function of monocytes are detected by FCM.

Objective To investigate the antibiotic resistance and the phenotype and genotype of metallo-β-lactamase in clinical isolates Chryseobacterium spp.Methods The MIC of 18 antibiotics in 50 Chryseobacterium spp.isolates was detected by agar dilution method.Phenotype of metallo-β-laetamase was detected by three-disc synergy test and modified three dimension test.Polymerase chain reaction(PCR)detection for metallo-β-lactamase gene was conducted for all isolates,and then the DNA sequence analysis was conducted for the PCR products which are positive for metallo-β-lactamase and identify genotype.conjugation experiment was used to study the transmission of metallo-β-lactamase encoding gene.pIs of β-lactamase was measured by isoelectric focusing assay. Results The antibiotic resistance of 50 clinical isolates of Chryseobacterium spp.against imipenem,Meropenem was 82.0%and 82.0%respectively.However,these isolated had high resistance to gatifloxacin.levofloxacin and rifampin compared with other antibiotics.Phenotype detection showed 33 isolated produced metallo-β-lactamase using three-disc synergy test and modified three dimension test,and the incidence of producing metallo-β-lactamase was 66.0%.Twenty isolateds producing Chryseobacterium indologenes were detected to have metallo-β-laetamase genotype by PCR amplification,among them 9 isolates containing blaIND-1 genotype and 10 isolateds containing blaIND-2 genotype.Strain CI-25 was identified to represent blaIND-LIKE genotype.Fourteen Chryseobacterium meningosepticum were detected to have metallo-β-lactamase genotype by PCR amplification,including 15 blaB and 2 blaGOB. The number of strain producing blaB1,blaB2,blaB3 and blaB11 in Chryseobacterium meningosepticum was 2,5,4 and 4,respectively. Conjugation experiments showed that metallo-β-lactamase encoding gene cannot be transfered. The extracted plasmid of 4 strains did not harbor metallo-β-lactamase gene.Strain C-5 was proved to have blaIND-1 gene,but its phenotype and IEF of metallo-β-lactamase was negative.Conclusions Chryseobacterium spp.had high frequency of multidrug resistance and high incidence for producing metallo-β-lactamase,and thus it was difficult to be treated.The gene of metallo-β-lactamase located on chromosome of Chryseobacterium spp.and cannot be transfered.There was negative or low lever of expression of blaIND-1.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).
METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.
RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.
CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.

Tetradrine-tashionone II(A)-PLGA composite microspheres were prepared by the SPG membrane emulsification method, and the characterization of tetradrine-tashionone II(A) -PLGA composite microspheres were studied in this experiment. The results of IR, DSC and XRD showed that teradrine and tashionone II(A) in composite microspheres were highly dispersed in the PLGA with amorphous form. The results of tetradrine-tashionone II(A) -PLGA composite microspheres in vitro release experiment showed that the cumulative release amounts of tetradrine and tashionone II(A) were 6.44% and 3.60% in 24 h, and the cumulative release amounts of tetradrine and tashionone II(A) were 89.02% and 21.24% in 17 d. The process of drug in vitro release accorded with the model of Riger-Peppas. Tetradrine-tashionone II(A) -PLGA composite microspheres had slow-release effect, and it could significantly reduce the burst release, prolong the therapeutic time, decrease the dosage of drugs and provide a new idea and method to prepare traditional Chinese medicine compound.
