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 explore the influence of intestinal trefoil factor (ITF) on interleukin-6(IL-6) in neonatal rat with necrotizing enterocolitis(NEC) ,and to discuss the protective machanism of ITF on NEC.Methods Thirty-two neonatal rats were divided randomly into four groups,group A as control group,group B as NEC group,group C as NEC+NS 0.2 mL group,group D as NEC+ITF 0.2 mg group.NEC model of neonatal rats were established.On the 4th day,all the subjects were put to death.Intestinal tissue within the boundary of ileum and cecum was obtained to observe histological changes.Other intestinal tissue was treated into homogenate.After the homogenate was centrifuged,supernates were used to test the density of IL-6.Results The density of IL-6 significantly decreased in group A,D than those in group B and C (Pa0.05).The pathological lesions indicated that intestinal tissue necrosis was severe in group B and C,which was graded as 3 points,but obviously lessen in group D,which was graded as 1 point,with ITF interfering.Conclusions Intestinal inflammation is ameliorated after ITF are injected hypodermically or intraperitoneally.ITF may provide a brand-new way for the therapy of NEC in neonatal rats.

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

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 correlation of blood-brain barrier (BBB) damage and depression in patients with cerebral small vessel disease (CSVD).Methods Consecutive patients with CSVD admitted to hospital were enrolled prospectively.The patients completed head MRI and cerebrospinal fluid (CSF) examination after admission.The BBB damage degree was evaluated by using albumin CSF/serum ratio (Q-Alb).At 3 months after onset,the depression was assessed according to the Hamilton depression scale (HAMD) and the American Diagnostic and Statistical Manual of mental disorders,4th edition (DSM-Ⅳ).The correlation between the BBB damage and depression in patients with CSVD was analyzed,Results A total of 130 consecutive patients with CSVD were enrolled,including 58 (44.62％) had depression within 3 months.There were significant differences in the proportions of patients with lacunar infarction (43.10％ vs.26.39％;x2 =4.008,P =0.045),leukoaraiosis (75.86％ vs.58.33％;x2 =4.408,P =0.036),and cerebral microbleed (27.59％ vs.12.50％;x2 =4.707,P =0.030),and baseline National Institutes of Health Stroke Scale (NIHSS) scores (5.02 ± 2.51 vs.3.60 ± 2.43;t =3.256,P =0.001),Fazekas scales of deep white matter (2.35 ± 1.00 vs.1.56 ± 1.05;t =4.358,P ＜0.001) and the proportion of Q-AIb category (x2 =6.852,P =0.033) between the depression group and the non-depression group.Multivariate logistic regression analysis showed that the baseline NIHSS scores (odds ratio [OR] 1.248,95％ confidence interval [CI] 1.027-1.517;P =0.026),leukoaraiosis (OR 14.786,95％ CI 1.776-123.111;P=0.013),Fazekas scales of deep white matter (OR 1.847,95％ CI 1.210-2.819;P=0.004),and Q-Alb (OR 30.417,95％ CI 3.662-252.643;P =0.004) had significant independent correlation with depression.Conclusions The BBB damage is independently associated with depression in patients with CSVD.

Objective:This work aims to investigate diallyl disulfide (DADS) inhibition of cell migration and invasion in human colon cancer SW480 cells through the Rac1-ADF/cofilin1 pathway. Methods:The potential of cell migration and invasion was examined by scratch healing assay and transwell membrane assay. The expression of Rac1-ADF/cofilin1 pathway was detected by RT-PCR and Western blot. Results:After the SW480 cells were treated with 40 and 50 mg·L-1 of DADS for 24 h, the number of transmembrane cells through the Matrigel obviously decreased by 57.12%and 64.59%, respectively (P<0.05). After cell treatment for 48 h, the cell migration rates were 23.23%and 12.87%, which were significantly lower compared with the control group (75.86%;P<0.05). After the cells were treated with 45 mg·L-1 of DADS for 24 and 48 h, the expression of Rac1, Rock1, PAK1, LIMK1, and destrin mRNA respectively decreased compared with the control group (P<0.05). However, no significant difference was observed in the expression of cofilin1 mRNA (P>0.05). After the treatment with 45 mg·L-1 of DADS for 6, 12, 24, and 48 h, the expression of Rac1, Rock1, PAK1, LIMK1, and Destrin proteins respectively decreased in a time-dependent manner compared with the control group (P<0.05). However, no significant differences were observed in the expression of the cofilin1 protein (P>0.05). Moreover, the expression of p-LIMK1 and p-cofilin1 notably decreased in a time-dependent manner (P<0.05). Conclusion:DADS inhibits cell migration and invasion, which is related to the down-regulation of Rac1, Rock1, PAK1, LIMK1, p-LIMK1, p-cofilin1, and destrin through the Rac1-ADF/cofilin1 pathway.
