Objective To study the effect of morin on LPS induced acute lung injury mouse model and its mechanism .Meth‐ods Thirty male C57B/L mice were randomly divided into control group ,LPS group and LPS+ morin group ,with 10 in each group .5 mg/kg LPS was instilled into the lung from an trachea intubation in LPS group and LPS+morin group .Then the mice in LPS+morin group received an intraperitoneal injection of morin (40 mg/kg) every day for the next 3 d .Others received an equal a‐mount of saline .After 72 h ,the mice were sacrificed .The bronchoalveolar lavage fluid (BALF) was collected and centrifuged;the sediments were stained with Wright‐Giemsa for total cell and neutrophil count and the supernates were prepared for ELISA .The wet and dry weight of lung was weighed to calculate the wet/dry weight ratio .HE staining was performed to examine the pathologi‐cal change of lung .Western blot was used to determined the expression of TLR4 ,IKK and NF‐κB .Results Intratracheal instillation of LPS successfully established ALI model in mouse .LPS caused significant pathological changes including inflammatory cells infil‐tration ,alveolar septa thickness ,hemorrhage and edema .The wet/dry weight ratio ,the total cell count ,neutrophil count ,TNF and IL‐1βlevel in BALF ,and the expression of TLR4 ,NF‐κB ,and IKK were all increased significantly (P<0 .05) ,which were allevia‐ted by intraperitoneal injection of morin .Conclusion Morin can dampen the inflammatory response during LPS induced ALI in mouse ,which is potentially attributed to its inhibitory effect on the activation of NF‐κB .

OBJECTIVE To evaluate the role of forkhead transcription factor p3(Foxp3) in the pathogenesis of allergic rhinitis(AR).METHODS Nasal tissues and peripheral blood mononuclear cells(PBMCs) were obtained from 17 patients with AR and 11 controls.Foxp3 was detected in nasal tissues by immunohistochemisry and real-time reverse transcription polymerase chain reaction(RT-PCR).Foxp3 and CD4+CD25+T cells were evaluated in PBMCs by using ? ow cytometry.RESULTS The numbers of Foxp3+ cells was(44.2?20.5)cells/mm2 and(129.5? 35.6)cells/mm2 in nasal mucosa of two groups(P

OBJECTIVETo investigate the density and distribution of nerve endings and neuropeptide Y (NPY) in lumbar facet joints of patients with low back pain.

METHODSFifteen patients without low back pain were selected as control group (group A). Facet joint samples in group A were obtained during the operation or lumbar spinal canal tumor they suffered from. Those patients with low back pain were divided into three groups according to their different origins of pain, such as not from facet joint (group B, 15 patients) ,from facet joint only (group C, 20 patients), or from facet joint partially (group D, 20 patients). Different origins were determined by VAS after facet joint block. The density and distribution of nerve ending and neuropeptide in the capsular tissues were analyzed by a modified gold chloride staining and immunochemistry respectively.

RESULTSCompared with the ones in group A and B, the fact joints in group C and D were more inclined to be degenerated and got more nerve endings. NPY was expressed mainly in the facet joint of patients with low back pain in group C and D. In addition, there was a significant relationship between the distribution of nerve endings and NPY expression,while none of them were related with MRI Fujiwara grade of facet joint.

CONCLUSIONThese results suggest that the number of mechanoreceptors, neural sprouting and secreted peptides in the facet joint capsules vary with the change of mechanical or nociceptive stimulation, which may promote the development of low back pain in return.

Objective To investigate the pathological types and features of lymph nodes in human immunodeficiency virus(HIV)/acquired immune deficiency syndrome(AIDS)patients with superficial lymphadenectasis.Methods The tissues of lymph nodes were obtained from 151 HIV/AIDS patients with superficial lymphadenectasis for pathological examination.The pathological results were observed by light microscope after Hematoxylin-Eosin(HE),acid-fast,periodic acid-Schiff (PAS),and digested-PAS(D-PAS)staining.The pathological results of lymph nodes were described and the correlation between pathological changes and CD4+T lymphocyte count was analyzed.Chisquare test was used for the statistic analysis.Results The benign lesions were found in 145 patients (96.0%),while the malignant tumors were found in 6 patients(4.0%).The pathological findings in the 151 HIV/AIDS patients included tuberculosis(72 patients),lymph node reactive hyperplasia(34patients),lymphatic fungal infections(23 patients,including penicillium diseases in 19 cases),AIDSrelated lymphadenectasis(14 cases),non-Hodgkin lymphoma(5 cases),benign fibrous histiocytoma (1 case).In addition,there were 83 patients(55.0%)with CD4+T lymphocyte count lower than 100×106/L.The frequency of penicillium diseases was higher in patients with lower CD4+T lymphocyte count(x2=7.757,P=0.021).Conclusions The major reasons for superficial lymphadenectasis in HIV/AIDS patients are infectious diseases,such as tuberculosis and fungal infections,which are common in patients with lower CD4+T lymphocyte counts.Non-Hodgkin lymphoma is the most common malignant tumor in this patient population.

Objective To access the long-term efficacy and safety of immunosuppression on the progression of IgA nephropathy (IgAN) by Meta analysis.Methods Databases EMBASE,Pubmed,Elsevier Science Direct,Scopus,Web of Science,Google Scholar,Cochrane Library,China National Knowledge Infrastructure,WanFang and VIP Data were retrieved to collect the randomized controlled trials (RCTs) at least 3 years follow-up on immunosuppression for IgAN published before May 2014.The literatures were screened independently by two reviewers according to the inclusion and exclusion criteria,and the methodological quality was assessed.Statistic software Stata 12.0 was used to conduct analysis.Results Nine articles were included in this study with a total of 568 patients.Immurnosuppression could lowered the risk for the progression to ESRD (RR=0.32,95％CI:0.20-0.49,P ＜ 0.01).As far as the efficacy of immunosuppression,subgroup analysis indicated that three studies with more than 7 year follow-up (RR=0.28,95％CI:0.13-0.59,P ＜ 0.01) were similar with 7 studies followed by for less than 7 years (RR=0.34,95％ CI:0.19-0.59,P＜0.01); six adopted immunosuppressor monotherapy (RR=0.29,95％ CI:0.15-0.58,P＜ 0.01) were similar to two used corticosteroids plus other immunosuppression (RR=0.33,95％CI:0.18-0.59,P ＜ 0.01); There were no significant differences between four studies from Europe (RR=0.27,95％CI:0.14-0.53,P ＜ 0.01) and five from Asia (RR=0.35,95％ CI:0.19-0.65,P＜0.01).Immunosuppression was associated with an increased risk for adverse events (RR=2.33,95％ CI:1.33-4.09,P＜0.01).Conclusion Immunosuppression for IgAN may reduce long-term risk of progression to ESRD,but increase the risk of adverse events to some extent.

Objective To investigate the molecular characteristics of immune response signaling molecules induced by transfection of coxsackievirus B2 ( CVB2 ) structural proteins into epithelial cells. Methods Recombinant eukaryotic expression plasmids containing the coding regions of CVB2 structural proteins VP1-VP4 were constructed and then transfected into 16HBE cells. Culture supernatants and cell ly-sates of the transfected 16HBE cells were collected. Expression of signaling molecules involved in innate im-mune responses in transfected 16HBE cells at mRNA level was detected by RT-Q-PCR. The proliferation of T cells co-cultured with culture supernatants and cell lysates of the transfected 16HBE cells was analyzed by ELISPOT. Results Expression of innate immunity-related signaling molecules such as TGF-β-activated ki-nase ( TAK) , NF-κB-inducing kinase ( NIK) , IκB kinase α ( IKKα) and IFN-β at mRNA level was up-regulated in 16HBE cells transfected with CVB2 structural proteins VP1-VP4. Both culture supernatants and cell lysates of the transfected 16HBE cells enhanced the proliferation of T cells. Conclusions CVB2 struc-tural proteins VP1-VP4 could enhance the expression of innate immunity-related signaling molecules to var-ying degrees and promote the activation of adaptive immunity.

OBJECTIVETo investigate the cleavage of HBV core protein in vivo by proprotein convertase furin or its family members and observe the intracellular localization of the putative cleaved product.

METHODSRecombinant HBV core protein was incubated with furin under different conditions in vitro, and the reaction was checked with Western blotting. The recombinant vectors expressed the putative cleaved fragment and intact core protein (serves as control) were constructed. The stable expression cell lines were established by transfecting constructs into HepG2 cell line, for which indirect immunofluorescence staining was used by monoclonal anti-HBc against the region shared by core protein and its cleaved product .The confocal microscopy was carried out to observe the intracellular distribution.

RESULTSHBV core protein was cleaved by furin in vitro under different tested conditions. The molecular weight of the major cleaved product just about 15,000 was in concordance with the expectation. The expressed cleaved fragment could react to the monoclonal antibody against core protein, and mainly located in cytosol in particle style just like the intact core protein.

CONCLUSIONHBV core protein can be cleaved by furin in vitro. The major cleaved product has similar antigenicity and subcellular distribution to core protein. These data suggest that proprotein convertase furin or its family members play important roles in HBV replication regulation, and the cleaved product may be involved in antiviral immunity of HBV infection. Further investigations are imperative.

OBJECTIVETo compare the differences of radiographical and functional outcomes between traditional and minimally invasive approach in treating Hawskins type I fractures of the talar neck.

METHODSFrom February 2000 to February 2008, 37 patients underwent reduction and internal fixation using two different approaches. In minimally invasive approach group, there were 16 males and 2 females, ranging in age from 20 to 47 years, averaged (35.2 +/- 3.1) years, and in traditional approach group, there were 15 males and 4 females, ranging in age from 22 to 44 years, averaged (35.3 +/- 2.3)years. All the patients had Hawskins type I fractures. The following data were compared between two groups: operation time, blood loss, length of incision and function of ankle joint. All the patients were graded by Hawkins points-scoring system after operation.

RESULTSAll patients were followed up. The duration ranged from 2 to 10 years, with an average of 5.6 years. The index such as operation time, blood loss and the length of incision of patients in minimally invasive approach group were significantly less than those of patients in traditional approach group. According to AOFAS points-scoring system, the score of minimally invasive group was higher than that of traditional approach group.

CONCLUSIONCompared with traditional approach, minimally invasive approach can protect blood supply better, get better clinical effects,which is worth of choosing to treat Hawskins type II fractures of talar neck.
