2Estrogen enhances the functions of CD4^(+)CD25^(+)Foxp3^(+) regulatory T cells that suppress osteoclast differentiation and bone resorption in vitro显示文摘Cross-talk has been shown to occur between the immune system and bone metabolism pathways.In the present study,we investigated the impact of CD4^(+)CD25^(+)Foxp3^(+) regulatory T(Treg)cells on osteoclastogenesis and bone resorption.Treg cells that were isolated and purified from peripheral blood mononuclear cells(PBMCs)of healthy adults inhibited both the differentiation of osteoclasts(OCs)from human embryo bone marrow cells(BMCs)and the pit formation in a dose-dependent manner.In cell cocultures,the production levels of both interleukin-10(IL-10)and transforming growth factor-beta 1(TGF-β1)were proportionally upregulated as the ratio of Treg cells to BMCs was increased,and the inhibition of OC differentiation and bone resorption by Treg cells was completely reversed by anti-IL-10 and anti-TGF-β1 antibodies.Treatment of BMC and Treg cell cocultures with 17β-estradiol(E2)at concentrations between 10^(-7) and 10^(-9) mol/l suppressed OC differentiation and bone resorption more efficiently than it did in cultures of BMCs alone;this enhanced suppression occurred via the stimulation of Treg cell IL-10 and TGF-b1 expression.These data suggest that Treg cells suppress OC differentiation and bone resorption by secreting IL-10 and TGF-β1.E2 enhances the suppressive effects of Treg cells on OC differentiation and bone resorption by stimulating IL-10 and TGF-β1 secretion from these cells.Therefore,Treg cell-derived IL-10 and TGF-b1 are likely involved in the regulation of E2 on bone metabolism and represent potential therapeutic targets for the treatment of postmenopausal osteoporosis(PMO).CY Luo L Wang C Sun DJ Li 2011Cellular & Molecular Immunology2011,8,1:33

4Magnetic resonance elastography is accurate in detecting advanced fibrosis in autoimmune hepatitis显示文摘To assess the value of magnetic resonance elastography(MRE) in detecting advanced fibrosis/cirrhosis in autoimmune hepatitis(AIH).METHODS In this retrospective study, 36 patients(19 treated and 17 untreated) with histologically confirmed AIH and liver biopsy performed within 3 mo of MRE were identified at a tertiary care referral center. Liver stiffness(LS) with MRE was calculated by a radiologist, and inflammation grade and fibrosis stage in liver biopsy was assessed by a pathologist in a blinded fashion. Two radiologistsevaluated morphological features of cirrhosis on conventional magnetic resonance imaging(MRI). Accuracy of MRE was compared to laboratory markers and MRI for detection of advanced fibrosis/cirrhosis.RESULTS Liver fibrosis stages of 0, 1, 2, 3 and 4 were present in 4, 6, 7, 6 and 13 patients respectively. There were no significant differences in distribution of fibrosis stage and inflammation grade between treated and untreated patient groups. LS with MRE demonstrated stronger correlation with liver fibrosis stage in comparison to laboratory markers for chronic liver disease(r = 0.88 vs-0.48-0.70). A trend of decreased mean LS in treated patients compared to untreated patients was observed(3.7 k Pa vs 3.84 k Pa) but was not statistically significant. MRE had an accuracy/sensitivity/specificity/positive predictive value/negative predictive value of 0.97/90%/100%/100%/90% and 0.98/92.3%/96%/92.3%/96% for detection of advanced fibrosis and cirrhosis, respectively. The performance of MRE was significantly better than laboratory tests for detection of advanced fibrosis(0.97 vs 0.53-0.80, P < 0.01), and cirrhosis(0.98 vs 0.58-0.80, P < 0.01) and better than conventional MRI for diagnosis of cirrhosis(0.98 vs 0.78, P = 0.002).CONCLUSION MRE is a promising modality for detection of advanced fibrosis and cirrhosis in patients with AIH with superior diagnostic accuracy compared to laboratory assessment and MRI.Jin Wang Neera Malik Meng Yin Thomas C Smyrk Albert J Czaja Richard L Ehman Sudhakar K Venkatesh 2017World Journal of Gastroenterology2017,23,5:15

9Pulmonary infection control window in treatment of severe respiratory failure of chronic obstructive pulmonary diseases: a prospective, randomized controlled, multi-centred study显示文摘Background Early withdraw from invasive mechanical ventilation (MV) followed by noninvasive MV is a new strategy for changing modes of treatment. This study was conducted to estimate the feasibility and the efficacy of early extubation and sequential noninvasive MV commenced at beginning of pulmonary infection control window in patients with exacerbated hypercapnic respiratory failure caused by chronic obstructive pulmonary diseases (COPD). Methods A prospective, randomized controlled study was conducted in eleven teaching hospitals' respiratory or medical intensive care units in China. Ninety intubated COPD patients with severe hypercapnic respiratory failure triggered by pulmonary infection (pneumonia or purulent bronchitis) were involved in the study. When the pulmonary infection had been controlled by antibiotics and comprehensive therapy, the 'pulmonary infection control window (PIC window)' has been reached. Each case was randomly assigned to study group (extubation and noninvasive MV via facial mask immediately) or control group (invasive MV was received continuously after PIC window by using conventional weaning technique).Results Study group (n=47) and control group (n=43) had similar clinical characteristics initially and at the time of PIC window. Compared with control group, study group had shorter duration of invasive MV [(6.4±4.4) days vs (11.3±6.2) days, P=0.000], lower rate of ventilator associated pneumonia (VAP) (3/47 vs 12/43, P=0.014), fewer days in ICU [(12±8) days vs (16±11) days, P=0.047] and lower hospital mortality (1/47 vs 7/43, P=0.025).Conclusions In COPD patients requiring intubation and invasive MV for hypercapnic respiratory failure, which is exacerbated by pulmonary infection, early extubation followed by noninvasive MV initiated at the start of PIC window may decrease significantly the duration of invasive MV, the risk of VAP and hospital mortality.Wang, C Zhan, QY Cao, ZX Wei, LQ Cheng, ZZ Liu, S Zhang, JL Chen, RC Luo, Q Niu, SF Zhu, L Wu, DW Fang, BM Wu, TH Wang, CZ Liu, YN 2005Chinese Medical Journal2005,,19:6

12Colonoscopy surveillance for high risk polyps does not always prevent colorectal cancer显示文摘AIM To determine the frequency and risk factors for colorectal cancer(CRC) development among individuals with resected advanced adenoma(AA)/traditional serrated adenoma(TSA)/advanced sessile serrated adenoma(ASSA). METHODS Data was collected from medical records of 14663 subjects found to have AA, TSA, or ASSA at screening or surveillance colonoscopy. Patients with inflammatory bowel disease or known genetic predisposition for CRC were excluded from the study. Factors associated with CRC developing after endoscopic management of high risk polyps were calculated in 4610 such patients who had at least one surveillance colonoscopy within 10 years following the original polypectomy of the incident advanced polyp. RESULTS84/4610(1.8%) patients developed CRC at the polypectomy site within a median of 4.2 years(mean 4.89 years), and 1.2%(54/4610) developed CRC in a region distinct from the AA/TSA/ASSA resection site within a median of 5.1 years(mean 6.67 years). Approximately, 30%(25/84) of patients who developed CRC at the AA/TSA/ASSA site and 27.8%(15/54) of patients who developed CRC at another site had colonoscopy at recommended surveillance intervals. Increasing age; polyp size; male sex; right-sided location; high degree of dysplasia; higher number of polyps resected; and piecemeal removal were associated with an increased risk for CRC developmentat the same site as the index polyp. Increasing age; right-sided location; higher number of polyps resected and sessile endoscopic appearance of the index AA/TSA/ASSA were significantly associated with an increased risk for CRC development at a different site. CONCLUSION Recognition that CRC may develop following AA/TSA/ASSA removal is one step toward improving our practice efficiency and preventing a portion of CRC related morbidity and mortality.Mohamad A Mouchli Lidia Ouk Marianne R Scheitel Alisha P Chaudhry Donna Felmlee-Devine Diane E Grill Shahrooz Rashtak Panwen Wang Junwen Wang Rajeev Chaudhry Thomas C Smyrk Ann L Oberg Brooke R Druliner Lisa A Boardman 2018World Journal of Gastroenterology2018,24,8:5
13Structure Investigation of Poly(vinyl alcohol)-Collagen Composite显示文摘Naturally derived collagen protein was mixed thoroughly with medical grade poly (vinyl alcohol)(PVA) at the ratio of 90:10 (w/w) and was crosslinked by formaldehyde to form a homogeneous composite membrane. The buIk structure of the membrane was characterized ly means of Xray diffraction (XRD) and transmission electron microscoor (TEM). The membrane surface Structure was investigated using Fourier transform-infrared spectroscopy (attenuated totalrefraction) (FTIR-ATR), electron spectroscopy for chemical analysis (ESCA) and contact angle measurement. lt was found that collagen and PVA can remain Stable. This was supported by the fact that no sign of phase separation had been observed. The use of crosslinking agent can Substantially influence the Structure of the composite. It is suggested that this new compositedeserves further investigation and is potentially usable as a biomedical material.Zhang, QQ Ren, L Liu, LR Wang, C 1997Journal of Materials Science & Technology1997,13,3:5

15Immunogenetic factors driving formation of ultralong VH CDR3 in Bos taurus antibodies显示文摘The antibody repertoire of Bos taurus is characterized by a subset of variable heavy(VH)chain regions with ultralong third complementarity determining regions(CDR3)which,compared to other species,can provide a potent response to challenging antigens like HIV env.These unusual CDR3 can range to over seventy highly diverse amino acids in length and form uniqueβ-ribbon‘stalk’and disulfide bonded‘knob’structures,far from the typical antigen binding site.The genetic components and processes for forming these unusual cattle antibody VH CDR3 are not well understood.Here we analyze sequences of Bos taurus antibody VH domains and find that the subset with ultralong CDR3 exclusively uses a single variable gene,IGHV1-7(VHBUL)rearranged to the longest diversity gene,IGHD8-2.An eight nucleotide duplication at the 3′end of IGHV1-7 encodes a longer V-region producing an extended Fβ-strand that contributes to the stalk in a rearranged CDR3.A low amino acid variability was observed in CDR1 and CDR2,suggesting that antigen binding for this subset most likely only depends on the CDR3.Importantly a novel,potentially AID mediated,deletional diversification mechanism of the B.taurus VH ultralong CDR3 knob was discovered,in which interior codons of the IGHD8-2 region are removed while maintaining integral structural components of the knob and descending strand of the stalk in place.These deletions serve to further diversify cysteine positions,and thus disulfide bonded loops.Hence,both germline and somatic genetic factors and processes appear to be involved in diversification of this structurally unusual cattle VH ultralong CDR3 repertoire.Thaddeus C Deiss Melissa Vadnais Feng Wang Patricia L Chen Ali Torkamani Waithaka Mwangi Marie-Paule Lefranc Michael F Criscitiello Vaughn V Smider 2019Cellular & Molecular Immunology2019,16,1:4
