Traditional Chinese Medicine (TCM) is the gem of Chinese culture,while TCM culture the root and driving force for its development.Higher learning institutes,one of whose main missions is innovating and inheriting culture,are playing the unique roles in promoting world-wide recognition of TCM culture through international cooperation due to the abundant resources in TCM academy,talent,clinical study and international education.Taking Jiangxi University of Traditional Chinese Medicine as an example,this paper has made constructive exploration and study on how to promote the international communication of TCM culture to allow the international community for better understanding and the application of TCM based on the analysis of current situation and experience summarization with literature investigation and case study.Effective measures that have been put forward include establishing TCM experiencing center,promoting the construction of Confucius Institute,proactively building TCM library,improving the standardization of TCM translation,optimizing approaches of TCM international communication,and speeding up the cultivation of TCM international communication talents.

[Summary] The genomic DNA was extracted from peripheral blood leukocyte of the patient with thyroid hormone resistance syndrome and 14 members of his family.The exons 1-10 of thyroid hormone receptor β (TRβ) gene were amplified by PCR.The products of PCR were sequenced directly to detect the gene mutation.The results showed that 3 members of this family were confirmed to have the C→T transition mutation at nucleotide 1 303 site within exon 10 of TRβ gene,and the missense mutation results in the substitution of histidine to tyrosine (H435Y).The heterozygous mutation may lead to the occurrence of thyroid hormone resistance syndrome.

OBJECTIVE To investigate the distribution and drug resistance of pathogenic bacteria which caused respiratory infection among suscepted patients and offer scientific basis for reasonable usage of antibiotics.METHODS Oropharyngeal swabs among 709 cases of respiratory infection neonates were investigated by the routine methods and drug resistance was analyzed by K-B method.RESULTS Totally 438 bacterial strains were isolated from 709 neonates.most of these bacteria were Gram-negative bacilli(70.3%),among which Haemophilus influenzae and Klebsiella pneumoniae were accounted for 39.8% and 10.3%,respectively;fungi and Gram-positive cocci were accounted for 23.5% and 6.2%.CONCLUSIONS Most strains present higher resistance rates to penicillin and ampicillin;but cefoxitin,amikacin,vancomycin,imipenem and the third generation cephalosporins are revealed with higher sensitivity rates for pathogenic bacteria in newborns.

Objective To find out households consumption of iodized salt in Xinjian county, and to provide scientific basis for prevention and treatment of iodine deficiency disorders(IDD). Methods From 2006 - 2010 in Jiangxi province, according to the direction of east, west, south, and north, nine townships(streets) were selected,in each township (street), 4 administrative villages (committees) were selected, in each administrative village(committee) 8 households were selected to collect their edible salt each year, direct titration method was adopted to detect salt iodine. Results From 2006 - 2010 a total of 1440 salt samples were collected, of which 1379 were qualified iodized salt, 34 unqualified, 27 non-iodized salt; iodized salt coverage rate, qualified iodized salt and iodized salt consumption rates were 98.13% (1413/1440), 97.59% (1379/1413) and 95.76% (1379/1440),respectively, and the rate of non-iodized salt was 1.88% (27/1440). Conclusions The intake rate of qualified iodized salt in Xinjian county have reached the standards of eliminating IDD. The quality of iodized salt should be improved in few counties. In the future, we should also increase the use of various forms advocacy of IDD prevention and treatment, and educate the masses to enhance self-protection awareness, so that they can consciously resist the salt smuggling, and refuse to buy non-iodized salt.

Objective To explore the expression of transporter associated with antigen processing (TAP) and major histocompatibility complex class (MHC)-Ⅰ molecule in malignant melanoma cell lines. Methods Three malignant melanoma cell lines, including A375, A875, and KZ28 cells as well as normal melanocytes were cultured. Western blot, reverse transcription PCR and flow cytometry were used to detect the protein and mRNA expression of TAP as well as the membrane expression of MHC-Ⅰ in these cells. Results A significant decrease was observed in the expression of TAP mRNA (t = 5.89, 4.45 and 4.57 re-spectively, all P< 0.01) and protein (t= 5.46, 4.32 and 4.67 respectively, all P< 0.01) in A375, A875 and KZ28 cells compared with the melanocytes, with the strongest decrease occurring in A375 cells. Similarly, the expression of MHC-Ⅰ molecule was significantly lower in A375, A875 and KZ28 cells than that in the melanocytes (t= 6.16, 5.22 and 5.61 respectively, all P< 0.01).Conclusions The protein and mRNA expres-sion of TAP is down-regulated in three melanoma cell lines A375, A875 and AZ28, which may contribute to the escape of melanoma cells from human immune surveillance.

Aim To explore whether 5-lipoxygenase inhibitor zileuton attenuates neuroinflammation and brain damage via modulating ERK1/2 signaling path-way in rats of cerebral ischemia, and further investigate the possible mechanisms. Methods Sprague-Dawley rats underwent the cerebral ischemic injury by the su-ture occlusion model, and were randomly divided into sham operation, MCAO, zileuton-treated and PD98059 groups. Neurological deficit scores, cerebral infarct volume, and cerebral water content were measured, myeloperoxidase ( MPO ) activities in rat brain were measured as an index of neutrophil infiltration;content of TNF-α in blood was determined by the method of ELISA;expression of p-ERK1/2 and t-ERK1/2 in rat brain were detected by Western blot. Results Zileu-ton reduced neurological deficit scores, cerebral infarct volume, cerebral water content, MPO activity and TNF-α content, all of which were abolished by PD98059 administration. Zileuton up-regulated the ex-pression of p-ERK1/2 , which was inhibited by PD98059 administration. Conclusions Zileuton at-tenuates neuroinflammation and ischemic brain damage through the activation of ERK1/2 signaling pathway.

Objective To construct an eukaryotic expression vector for TAP genes fused with enhanced green fluorescent protein(EGFP)gene,and to analyze the expression and subcellular localization of the fusion protein in A375 human malignant melanoma cells transfected with the eukaryotic expression vector.Methods A375 cells were cotransfected with the combination of plasmid(P)TAP1-EGFP or pTAP2-EGFP and pDsRed2-endoplasmic reticulum(ER),or with pEGFP-TAP1 and-TAP2,or monotransfected with pTAP1-EGFP or pTAP2-EGFP alone.The monoclonal A375 cells stably expressing TAP were obtained by G418 selection.Then.the distribution and expression of fusion proteins were assessed in A375 cells by using fluorescence microscopy and Western blot,respectively.Flow cytometry was used to measure the expression of HLA class Ⅰ on A375 cells.Results Transfection of A375 cells with pTAP1-EGFP or pTAP1-EGFP and pTAP2-EGFP significantly increased the expression of TAP 1 and TAP 2 in as well as HLA class Ⅰ antigen on A375 cells.The green fluorescence of TAP1-EGFP and TAP2-EGFP overlapped with the red fluorescence of ER marker in cotransfected cells.indicating that TAP was localized subcellularly on the ER.Conclusions The expression vector for TAP-EGFP fusion gene has been constructed cuccessfully and expressed in A375 cells,and the expressed fusion protein is subcelluiarly localized to ER.This study will provide a basis for the research into subsequent immune response following induction of TAP expression.

Objective To study the expression of cellular FLICE inhibitory proteins(c-FLIP)in peripheral blood B lymphocytes in patients with systemic lupus erythematosus (SLE)and its correlation with clinical features.Methods Blood samples were obtained from 53 patients with SLE and 30 normal human controls.Flow cytometry and ELISA were performed to measure the expression of c-FLIP in pefipheral blood B lymphocytes and serum levels of IL-4 and IL-10,respectively.Relevant laboratory examinations were carried out for these patients.SLE disease activity index(SLEDAI)score was calculated for patients.Results The positivity rate of c-FLIP in B lymphocytes was 3.11%±0.70%in 18 patients with active SLE.significantly higher than that in 35 patients with inactive SLE (0.78%±0.28%)and normaI controls(0.68%±0.12%),while no statistical difierence was found between inactive patients and controls(t=1.56,P＞0.05).In SLE patients,the expression of c-FLIP showed a positive correlation with SLEDAl score(r=0.96.P＜0.05),erythrocyte sedimentation rate(r=0.96,P＜0.01),serum level of C reactive protein(r=0.92.P＜0.01)and the titer of antinuclear antibodies(r=0.86,P＜0.01),whereas in 36 patients with leucopenia.a negative correlation was noticed between white blood cell count and the expression level of c-FLIP(r=-0.94,P＜0.0 1).The 23 patients with lupus nephritis had a higher level of c-FLIP than those without lupus nephritis(3.04%±1.09%vs 1.76%±1.09%,t=4.23,P＜0.05).Additionally.the expression of c-FLIP positively correlated with the serum level of IL-4 and IL-10(r=0.80,0.89.respectively,both P＜0.01).Conclusions In patients with active SLE,the expression of c-FLIP is upregulated in peripheral blood B lymphocytes,and positively correlated with the severity of SLE as well as the serum level of IL-4 and IL-10.The upregulation of c-FLIP in B cells might play a certain role in deficient apoptosis or clearance of activated B cells in SLE.

Objective To investigate the expression of glucose transporter type 1(GLUT-1)and hypoxia-inducible factor 1 (HIF-1)α in psoriatic lesions,and to explore their correlations with keratinocyte proliferation.Methods Biopsy specimens were obtained from 30 patients with psoriasis and 20 normal human controls.Immunohistochemistry and Western blotting were used to examine the protein expression of GLUT-1 and HIF-1α in these specimens.Results GLUT-1 and HIF-1α were mainly expressed in the basal layer of the control skin,but throughout the whole epidermis of psoriatic lesions.A significant increase was observed in the expression of GLUT-1 and HIF-1α in psoriatic lesions compared with that in the control skin (botb P＜0.01).In the case of psoriatic lesions,both the expression of GLUT-1 and HIF-1α was positively correlated with that of Ki-67(r=0.70,0.81 respectively,both P＜0.01),and positive correlation was also found between the expression of GLUT-1 and HIF-1α(r=0.85.P＜0.01).Conclusion Our data suggest that uprcgulation Of GLUT-1 and HIF-1α expression in psoriatic lesions might contribute to the proliferation of keratinocytes and psoriasis development.

Objective To investigate the expression and distribution of cellular FLICE-inhibitory protein (c-FLIP) in peripheral blood and lesions of psoriatic patients. Methods Peripheral blood and skin samples were obtained from 30 patients with psoriasis vulgaris and 20 normal controls. Flow cytometry was used to detect intracellular c-FLIP protein in peripheral T and B lymphocytes, immunohistochemistry to examine the expression of c-FLIP in lesional tissue.
