Peritoneal macrophages from thioglycollate-treated C57BL/6 mice were separatedby centrifugation on Percoll discontinuous gradients.Macrophages were so separ-ated into four subpopulations and their tumor cytotoxicity and the effect of sodi-um selenite on different subsets were studied.There was no marked difference inphagocytic activity and Fc recepter activity among the four subpopulations.High-density macrophages activated by MAF were kighly cytostatic and cytolyticto tumor cells,while low-density macrophages were not Peritoneal injection of sodiumSelenite(lmg/kg)augmented macrophage-mediated cytotoxic activity by increasingtheir MAF responsiveness which occurred mainly in the low-density macrophages.sodium selenite did not affect macrophage maturation as the percentage of theperoxidasepositive macrophages remained unchanged,

Totally 80 rats were randomly divided into the control group, the model group, low, middle and high dose (25, 50, 100 mg x kg(-1)) scutellarin( SC) groups and the colchicine ( Col) group. Apart from the blank group, all of the remaining groups were intraperitoneally injected with 0.5 mL pig serum twice every week for consecutively 13 weeks and orally administered with the corresponding drugs since the 9th week. The blank group and the model group were orally given equal volume of normal saline once every for consecutively four weeks. After the experiment, efforts were made to detect the contents of alanine aminotransferase (ALT), aspertate aminotransferase (AST), albumin (ALB), total protein (TP), total bilirubin (TBIL), hyaluronic acid (HA), laminin (LN) and collagen type IV (CIV), collect liver tissues of fixed positions, observe the pathological changes through hematoxylin-eosin (HE) staining, conduct the pathological grading for liver fibrosis, determine the expressions of hepatic collagen type I and III (C I, C III) and calculate their color rendering index. Compared with the model group, low, middle and high dose (25, 50, 100 mg x kg(-1)) SC groups could decrease the contents of ALT, AST, TBIL, HA, LN, CIV, increase the contents of ALB, TP in serum and reduce the contents of C I, C III in liver tissues. In conclusion, scutellarin has a certain therapeutic effect on immune liver fibrosis in rats induced by pig serum.

Objective To investigate the clinical effect of intra-articular injection of sodium hyaluronate combined with psychological intervention in the treatment of knee osteoarthritis.MethodsA total of 90 patients with knee osteoarthritis treated in our hospital from June 2015 to June 2016 were selected as the research object, according to the different treatment methods, the patients were divided into two groups,with 45 cases in each group.The patients in the control group were treated with conventional treatment, while the observation group was treated with conventional therapy and intra-articular injection of sodium hyaluronate.The experimental data of the two groups were compared.ResultsAfter treatment, the changes of knee joint pain score, joint effusion and joint mobility in the observation group is better than those in the control group.The change of knee function score in the observation group was better than that in the control group.The clinical therapeutic effect of the observation group (95.6%) is better than that of the control group (75.6%);There was significant difference between the two groups (P<0.05);There were no serious adverse reactions in the two groups of patients receiving treatment,and there was no significant difference between the two groups.ConclusionThe clinical effect of intra-articular injection of sodium hyaluronate combined with psychological intervention in the treatment of knee osteoarthritis is good, which is worthy of clinical application.

Objective To investigate the impacts of γ-ray radiation on gene expressions of peripheral blood lymphocytes in SD rats,and to screen differential expression genes and biological pathways closely related to radiation injury.Methods The differential gene expression of peripheral blood lymphocytes in SD rats was selected by microarray at 6 h after 2 Gy 60Co γ-ray exposure in vitro and in vivo.Bioinformatics analysis of the differentially expressed genes was performed by using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases.Real-time quantitative PCR was applied to verify the screen results of the microarray.Results Fifty-five genes with three times over-expressed level were screened out from the radiation groups both in vitro and in vivo and they were involved in 6 signaling pathways.There were two differentially expressed genes of microarray assay were verified by PCR assay.Conclusions Differential expressed genes in the peripheral blood lymphocytes of SD rats could be induced by γ-ray radiation and they cooperatively contributed to a variety of biological processes.

Neuronal α4β2 nicotinic acetylcholine receptors (nAChRs) are the most widespread subtypes in central nervous system, α4β2 nAChRs mainly exist in procerebrum, parietal lobe cortex, temporal lobe cortex, hippocampus, basal ganglion and cerebellum. Researches on gene knock-out mice have demonstrated that α4β2 receptors participate in the development, aging, neuron survival, pain, and learning and memory, and are also involved in gamma-aminobutyric acid release and dopaminergic function. Studies have disclosed that α4β2 nAChRs relate to the development of variety of neurological diseases, including pain, Alzheimer's disease and Parkinson's disease.

BACKGROUND:Our previous study has already manifested that Chinese medicine Xiaokening can effectively prevent and treat the early diabetic nephropathy. OBJECTIVE:To compare the effect of rhein and archen on the apoptosis of mesangial cells of rats cultured with high glucose. METHODS:Mesangial cells were stimulated by different concentrations of rhein and archen (20, 40 and 80 μmol/L). Morphology of apoptotic cells was observed by hematoxylin-eosin staining. Karyon apoptosis was examined by fluorescence staining of DAPI. cellapoptosis rate was detected by flow cytometry. RESULTS AND CONCLUSION:The outcome of hematoxylin-eosin staining and DAPI staining indicated that the effect of rhein was much stronger than that of archen on the apoptosis of mesangial cells in the rats cultured with high glucose. Comparison of the apoptosis rate also indicated that the rhein had a stronger effect on the earlier and the later stage apoptotic rate of mesangial cells than archen. Both rhein and archen with different concentrations can induce apoptosis of mesangial cells, but the effect of rhein is much stronger.
