Objective To study the correlation between scan orientation and the detectability of rotator cuff injury.Methods Different scan orientations of magnetic resonance imaging of the rotator cuff injury were analyzed in high magnetic field in 103 patients.Results The supraspinatus tendon and signal abnormities were obtained in 103 patients,the infraspinatus tendon and signal abnormities in 53 patients,subscapular tendon and signal abnormities in 18 patients,knolls tendon and signal abnormities in 15 patients.The oblique coronal MR imaging was clearest in supraspinatus tendon,while at the axial images was clearest in infraspinatus tendon.Conclusion Rotator cuff and the surrounding tissue injury could be clearly scanned in high magnetic field,the detectability of rotator cuff injury depended on different scan orientations of magnetic resonance imaging.

After the application of associated data in digital library and in library resources integration was described, the necessity of library resources integration was analyzed, the semantic association process of library resources and the problems of library resources in research on semantic association were studied in terms of system construction, technical implementation and discovery algorithm. The semantic integration of library resources was achieved by de-signing the integration framework, ontology and associated data.

Objective:To explore the effects of cerebrospinal fluid contained Sijunzi Decoction on function of colon mucosa lymphocytes of ulcerative colitis in vitro. Methods: Prepared the rat cerebrospinal fluid contained Sijunzi Decoction or Mesalamine. Collected colon mucosa of the 12 healthy ( as normal group ) and 18 ulcerative colitis, then isolated and obtained lymphocytes from these samples. The lymphocytes were divided into pathological group, IL-12 group, cerebrospinal fluid group cerebrospinal fluid contained Sijunzi Decoction group, cerebrospinal fluid contained Mesalamine group. After exposing to various treatment,the proliferative capacity was measured by CCK-8,the cell cycle and the ratio of CD4+T was analyzed by flow cytometry (FCM), the content of IL-1, IL-6, TNF-α was detected by ELISA. The expression of IL-2 were detected by Western blot analysis. Results:Compared the cerebrospinal fluid contained Sijunzi Decoction group with the IL-12 group or cerebrospinal fluid group,the proliferative capacity and the percentage of CD4+T was decreased, the cells significantly arrested at G0/G1 phase, the secretory capability of IL-1, IL-6, TNF-α were obviously reduced; the expression of IL-2 was also significantly down-regulated. Conclusion:The cerebrospinal fluid contained Sijunzi Decoction could decrease the function of colon mucosa lymphocytes of ulcerative colitis,the mechanism involved in may be Sijunzi Decoction regulating the secretory capability of IL-1,IL-6 and TNF-α.

Objective To investigate the effect of hyperbaric oxygen therapy on T-lymphocyte subpopulations in rats with acute pancreatitis. Methods 56 rats were randomly divided into three groups the sham group ( n = 8 ),control group( n = 24) and hyperbaric oxygen therapy group( treatment group, n = 24), then the control group and treatment groups were divided into three subgroups of 8 rats each undergoing euthanasia on days 1,3,7 after the acute pancreatitis induction. The CD4+ ,CD8+ subpopulations of T-lymphocytes in peripheral blood were detected respectively at the fist day and each day of the euthanasia. The sham group was used to make sure that the model was successfully induced. After euthanasia the pancrea was examined using electron microscopy. Results In the control group, the CD4+ cells in AP rats was significantly decreased and the ratio of CD4+/CD8+ also decreased. After 7days of HBO therapy,compared with the control group, the CD4+ lymphocytes of peripheral blood in the treatment group markedly increased( P ＜0.01 ). The CD8+ lymphocytes also increased to a certain extent. And the CD4+/CD8+ ratio of peripheral blood was obviously increased(P ＜0. 01 ). Also more severe pathological changes appeared in the untreated group than in the treatment group. Conclusion Hyperbaric oxygen therapy could improve the oxygen supply in acute panereatitis, regulate T cell immune function.

Toll like receptors (TLRs) are the earliest discovered natural immune pattern recognition receptors (PRRs). The abnormality of TLR signal transduction pathway is the key factor leading to chronic inflammatory, cancer, nervous system disease and cardiovascular diseases. The development of TLR agonists and inhibitors has attracted much attention. Currently known TLR2 agonists, such as lipopeptides or their derivatives, have certain limitations in drug development due to their difficult synthesis, easy hydrolysis, and triggering inflammatory cytokine storms, while inhibitors have been rarely reported. New small molecule TLR2 agonists or inhibitors with higher stability are more likely to be developed as tumor immunotherapy or anti-inflammatory drugs.

Objective To investigate the effect of L-camitine on renal ischemia-reperfusion (IR) injury (IRI) and Nrf2-ARE signaling pathway in rats.Methods Rats were randomly separated into the following experimental groups:control group (group C),IRI group (group I) and L-carnitine group (group L).Rats accepted no treatment of ischemic reperfusion in group C.In groups I and group L,the renal IRI model was established.L-carnitine was injected through the tail vein in group L,while the equal volume of saline was injected in group C and group I.Rats were killed at 3,6,and 24 h after IR.The levels of serum creatinine (Cr) and blood urea nitrogen (BUN),the activity of superoxide dismutase (SOD) and the content of malonaldehyde (MDA) in serum were measured.The histopathological lesions were observed in renal tissues after 24-h IR.RT-PCR was used to detect the levels of Nrf2,HO-1 and γ-GCS mRNA.Western blotting and immunohistochemistry were used to detect the levels and localization of Nrf2 protein in renal tissues after 6-h IR.Results The levels of Cr and BUN in group I and group L were higher than those in group C at 3 h after IR.At 6 h after IR,the levels of Cr and BUN in group L were lower than those in group I (P＜0.01 ).At 24 h after IR,the levels of Cr and BUN in group L were still lower than those in group I though both of them were reduced (P＜0.05).At all time points,the activity of SOD in group L was higher and the content of MDA was lower than those in group I (P＜ 0.05). As compared with group I,the renal histopathological lesions were alleviated in group L at 24 h after IR.At 6 h after IR,levels of Nrf2,HO-1,γ-GCS mRNA and Nrf2 protein in group I were increased as compared with group C,but decreased as compared with group L.Beyond that,the expression of nuclear Nrf2 protein in group L was higher than that in group I.Conclusion L-carnitine can protects the kidney against IRI significantly,which may be due to the up-regulated expression of antioxidant genes by activating the Nrf2-ARE signaling pathway.

A commonly used Chinese crude drug Allii Macrostemonis Bulbus has been shown to possess good anticancer activities and related properties such as antioxidation, nitrite scavenging, nitrosamine synthesis blocking and immune enhancement, and has been widely used as an effective auxiliary drug in the treatment of some malignant tumors.
