Objective Matrix-assisted laser desorption ionization-time of might-mass spectrometry (MALDI-TOF-MS) was utilized to analyze the protein fingerprint in brain-gut interaction of irritable bowel syndrome (IBS) model rats' colon, so as to find the clues for IBS. Methods Fourteen healthy male adult Wistar rats were selected and divided into a control and a chronic and acute stress ( CAS) group. Colon motility, visceral sensation and behavior changes of rats were detected to evaluate the model. MALDI-TOF-MS was used to observe the overall view of protein in colon so as to study whether there are abnormalities of protein levels in IBS. Results As compared with those in the control group, the number of fecal pellets [ (6. 00 ± 1. 69 ) pellets/1 h vs ( 1. 14 ± 0. 69 ) pellets/1 h, P < 0. 01 ] and frequency of abdominal contraction induced by colorectal distention (CRD) increased, while the amount of weight gain [ (298. 88 ± 18.61)gvs (348. 00±12. 44)g, P<0.01] and consumption of sucrose solutions [ (13. 63 ± 1. 69) ml/1 h vs (19.00±3.06) ml/1 h, P<0.05] decreased in the CAS group (P <0. 05). As far as protein/peptide quality different peak was concerned, CAS rats had 12 different peaks compared with the control rats. The different proteins could be divided into 4 types, which were related to iron secretion, protein synthesis, G protein system and immunity. The protein levels of the model group were higher than those in the control group (P < 0. 05). Conclusions The CAS rats integrate the major characteristics of IBS such as altered colon motility, higher visceral hypersensitivity and psychiatric disorder and can mimic the brain-gut interaction of IBS partly. The detection of differential proteins provides reference for the pathogenesis and treatment of IBS.

Objective To detect the expression of scleroderma-related autoantibodies, such as anti-Scl-70, anli-centromere antibody ( ACA)and anti-RNA polymerase Ⅲ ( ARA) , and their relationship with clinical features in Chinese systemic sclerosis (SSc) patients. Methods One hundred and thirty-five Chinese SSc patients from the clinical database of the Scleroderma Trials and Research Group proposed by European League Against Rheumatism's Scheroderma Trial and Research Group( EUSTAR) were consecutively enrolled. The expression of ARA, anti-Scl-70 and ACA were detected through linear immunoblotting, double immunodiffusion and indirect irnmunofluorescence, respectively. The relevance between the existing of autoantibodies and clinical manifestations was analyzed statistically. Results Among the 135 Chinese SSc patients, the prevalence of anti-Scl-70, ACA, ARA were 49. 6% , 13.3 % and 8.9% respectively. Patients with anti-Scl-70 antibody had significantly shorter disease course [(71 ±59) month vs (90 ± 103) month, P = 0.041] , higher proportion of interstitial lung disease ( P = 0. 031) but lower of pulmonary arterial hypertension (P =0.042). Modified Rodnan's skin score (P=0.008) and prevalence of facial and cervical cutaneous sclerosis (P = 0. 002) , distal (to elbow/knee ) cutaneous sclerosis ( P = 0. 004 ) and digital pitting scarring/disappear of digital pad were all significantly higher in anti-Scl-70 positive group. Patients with AC A had longer disease course ( P = 0. 036) , lower IgM level ( P = 0. 045) and were less prevalent of interstitial lung disease ( P =0. 045). Patients with ARA had higher serum creatinine and urea nitrogen level ( P < 0.001) although otherwise features had unremarkable differences. Conclusion Scleroderma-related autoantibodies have relevance with different clinical manifestation and detection of these autoantibodies may be helpful to the diagnosis of SSc, organ involvement evaluation and predicting outcomes. The clinical relevances of autoantibodies in Chinese SSc patients may differ from other areas or races.
