Objective To assess the clinical significance of antibodies against cyclic citrullinated peptide(anti - CCP) in a cohort of patients with juvenile idiopathic arthritis (JIA). Methods The anti - CCP was tested by an enzyme linked immunosorbent assay (ELISA) in serum samples from 22 patients with JIA(9 boys, 13 girls), with a mean age of 9.1 years(range 1.1 - 16). As control groups, anti - CCP were also tested in sera of 20 healthy children, and 30 adult patients with rheumatoid arthritis(RA). Results Positive anti - CCP were found in sera of 2 patients with JIA(9.1 %), both with lower titre comparing with those of adult patients with anti - CCP positive. In the control groups, none of healthy children was positive for anti - CCP, but 16/30(53. 3%) adults with RA showed anti - CCP positivity. Conclusion Anti - CCP can be detected in children with JIA, but are less frequently present than in adults with RA, so anti - CCP has limited diagnostic value to JIA.

Objective To study the effect of intestinal trefoil factor(ITF) on nuclear factor-?B(NF-?B) in neonatal rats intestinal tissues with necrotizing enterocolitis(NEC),and to discuss whether ITF had protective function in NEC,and its role in the mechanism of NEC.Methods Fifty neonatal rats were randomly divided into 5 groups:group A as control group,group B as control plus ITF 0.2 mg group,group C as NEC group,group D as NEC plus normal saline(NS),group E as NEC plus ITF 0.2 mg.NEC models of neonatal rats were established.On the 4th day,all subjects were put to death.The intestinal tissue located at the boundary of ileum and cecum were obtained to observe histological changes and NF-?B level.Results The density of NF-?B(p65) increased significantly in group C and D compared with those in group A,B and E(Pa

Taking mesoporous molecular sieve MCM-41 as a substrate, baicalin (BA) as template, acrylamide (AM) as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as a cross-linking agent, ethanol as solvent, under thermal polymerization initiator of azobis isobutyronitrilo (AIBN) , a kind of selective recognition of baicalin surface molecularly imprinted polymer was synthesized. The surface morphologies and characteristics of the MIPs were characterized by infrared spectroscopy (IR) and transmission electron microscope (TEM). The adsorption properties of polymer microsphere for the template were tested by the dynamic adsorption equilibrium experiments and static adsorption equilibrium experiments. The experiment showed that the imprinting process was successfully and the well-ordered one-dimensional pore structure of MCM-41 was still preserved. Furthermore, molecularly imprinted polymers had higher selective ability for BA, then provided a new method for the efficient separation and enrichment of baicalin active ingredients from medicinal plants Scutellaria baicalensis.

Objective To evaluate the effects of curcumin on the expression of receptor for advanced glycation end-products (RAGE) in the spinal dorsal horn and dorsal root ganglion (DRG) of the rats with type 2 diabetic neuropathic pain (DNP).Methods Male Sprague-Dawley rats,weighing 160-180 g,were used in this study.Type 2 diabetes mellitus was induced by high-fat and high-sucrose diet for 8 weeks and intraperitoneal streptozotocin (STZ) 35 mg/kg and confirmed by fasting blood glucose level ≥ 16.7 mmol/L 3 days later.Type 2 DNPwas confirmed by the mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) measured on day 14 after STZ administration less than 80％ of the baseline value.Eighty-one rats with type 2 DNP were randomly divided into 3 groups (n =27 each) using a random number table:DNP group,DNP + curcumin group (DCur group),and DNP+ solvent group (group DSC).In DCur and DSC groups,curcumin 100 mg· kg-1 · d-1 and corn oil 4 ml · kg-1 · d-1 were injected intraperitonally,respectively,for 14 consecutive days starting from the day 14 after STZ administration.Another 27 normal male Sprague-Dawley rats served as control group (group C) and were fed with normal forage.MWT and TWL were measured before STZ injection,at day 14 after STZ injection,and on 3,7 and 14 days after curcumin injection.RAGE positive cells were determined by immuno-histochemistry and the expression of RAGE by Western blot in the spinal dorsal horn and DRG after MWT and TWL were measured on 3,7 and 14 days after curcumin injection.Results Compared with group C,MWT was significantly decreased and TWL was shortened at 14 days after STZ injection and each time point after curcumin injection,the rate of RAGE positive cells in the spinal dorsal horn and DRG was increased at each time point after curcumin injection,and the expression of RAGE was up-regulated in the spinal dorsal horn at each time point after curcumin injection and in the DRG at 7 and 14 days after curcumin injection in group DNP.Compared with group DNP,MWT was significantly increased and TWL was prolonged at each time point after curcumin injection,the rate of RAGE positive cells in the spinal dorsal horn and DRG was significantly decreased at 7 and 14 days after curcumin injection,and the expression of RAGE was down-regulated in the spinal dorsal horn at each time point after curcumin injection and in the DRG at 7 and 14 days after curcumin injection in group DCur,and no significant change was found in the parameters mentioned above in group DSC.Conclusion The mechanism by which curcumin attenuates DNP may be related to inhibition of up-regulated expression of RAGE in the spinal dorsal horn and DRG of rats with type 2 diabetes mellitus.

Objective To investigate the co-morbid state of mental disorder in patients with functional dyspepsia (FD) in a tertiary general hospital in China and explore the risk factors of the co-morbidity of FD and major depressive disorder(MDD).Methods This study was designed as a bilateral evaluation and structural psychiatric interview.Patients with FD and newly diagnosed outpatients with MDD in gastrointestinal and psychological departments were enrolled.FD was defined by Rome Ⅲ criteria.The questionnaires including symptoms of FGIDs Roma Ⅲ,the composite international diagnostic interview (CIDI 3.0) Chinese version,the Hamilton depression/anxiety rating scale (HAMD/HAMA),Montgomery-Asberg depression scale (MADRS) were involved in this study.All patients were administered by well trained physicians and investigators in face to face interview.Results A total of 69 patients have completed the valid questionnaires and interview,among whom 42 met FD criteria (FD group) and 27 with FD co-morbid MDD (co-morbid group).Male to female ratios were 17∶25 and 10∶ 17,the mean age (42.1 ± 13.3) and (43.1 ± 15.3)years respectively.The life-long co-morbidity of FD and MDD was 39.1％ (27/69),while 31.9％ (22/69) patients with FD were accompanied with other mental disorders rather than MDD.Patients in FD co-morbid MDD group had significantly more severe depression than those in FD group with HAMD-17 score 21.6 ± 8.0 and 14.5 ± 7.6,HAMA score 21.2 ± 9.0 and 14.9 ± 7.5 respectively (all P ＜ 0.01).Logistic regression analysis showed that high score of MADRS and complication with functional anorectal disorder may be the risk factors of FD co-morbid MDD [OR (95％ CI) 1.12 (1.06-1.19) and 7.07(1.12-44.53)].Conclusions The co-morbidity rate of FD with MDD in our hospital is high.In addition to MDD,other mental disorders also need to be paid attention in FD patients.FD co-morbid MDD patients suffered more severe depression and anxiety.The high score of MADRS and complication with functional anorectal disorder seem to be the risk factors of co-morbidity of FD and MDD.
