Objective:To evaluate the value of serum anti citrullinated antibody ( anti CCP-Ab) ,anti keratin antibody ( AKA) and rheumatoid factor ( RF) diagnostic significance of these 3 kinds of index in RA.Methods:256 patients with RA ,92 patients with other autoimmune diseases,50 cases of healthy people were anti CCP-Ab,AKA,RF detection,and the results were analyzed.Results:single target detection ,diagnostic sensitivity of RA from high to low was RF ,anti CCP-Ab,AKA,specific from high to low was AKA ,anti CCP-Ab, RF,anti CCP-Ab and AKA combined detection in clinical diagnostic efficiency.Conclusion: RF,AKA,anti CCP-Ab three index have advantages and disadvantages in diagnosis of RA ,the diagnosis of AKA ,anti CCP-Ab serum of RF negative RA is a powerful complement to,in accordance with the selection of project portfolio appropriate experimental conditions ,the early diagnosis of RA and early treatment ,improve the prognosis had higher value.

Objective To investigate the therapeutic effects of Saussurea involucrate injection in severe acute pancreatitis (SAP) in rats.Methods A total of 80 healthy Sprague-Dawley rats were divided into eight groups:SAP group (three hours、48 hours),Saussurea involucrate treated group (three hours、48 hours),ulinastatin control group (three hours、48 hours) and sham operation group (three hours、48 hours),10 rats in each group.After modeling,the rats of SAP group were regularly feeded and the rats of other three group were treated with Saussurea involucrate injection (1.04 mL/kg) intraperitoneal injection,ulinastatin 10 000 U/L tail vein injection,and saline femoral vein injection,respectively and injected every 12 hours.At three hours and 48 hours after treated,blood and pancreatic tissue samples were obtained.The mortality rate,serum amylase level and pathological changes of the pancreas of each group were observed.Serum tumor necrosis factor alpha (TNF-α),interleukin (IL)-6 and IL-10 levels were detected by enzyme linked immunosorbent assay (ELISA).The content of malondialdehyde (MDA) in pancreatic tissues was determined by chemical colorimetry.The level of TNF-α mRNA,IL 6 mRNA and IL-10 mRNA in pancreatic tissues were measured with reverse trascription-polymerase chain reaction (RT-PCR).The activity of nuclear factor kappa B p65 (NF-κB p65) in the pancreatic tissue was tested by immunohistochemistry.Single factor analysis of variance was used to compare multiple groups,and the least significant difference (LSD) method was used in the multiple comparisons between groups.Fisher's exact probability method was performed for rates comparison.Results At 48 hours,there was no statistically significant difference in mortality rate among Saussurea involucrate treated group,SAP group and ulinastatin groups (all P＞0.05).At 48 hours,the histopathology score (8.13 ± 0.64),levels of serum amylase ((2 597.0±214.0) U/L),TNF-α ((254.4±11.6) ng/L),IL-6 ((441.4±14.6) ng/L),levels of pancreatic tissues MDA ((311.0±10.6) mmol/L),TNF-α mRNA(2.04±0.08),IL-6 mRNA (1.77±0.04)and activity of NF-κB p65 ((25.90±2.90)％) of Saussurea involucrate treated group were all lower than those of SAP group (11.40±0.89,(4 780.0±101.0) U/L,(396.0±7.4) ng/L,(664.4± 7.6) ng/L,(418.0± 10.6) mmol/L,2.94±0.03,2.63±0.08 and (51.60±5.27) ％;however level of serum IL-10 ((133.5±6.9) ng/L vs (95.1±5.2) ng/L) and IL-10 mRNA of the pancreatic tissue (1.38±0.06 vs 0.85±0.03) significantly increased (F=253.07、441.63、489.40、2 465.00、196.65、477.89、562.79、131.70、560.18、570.04,all P＜0.01).There was no significant differences in all above parameters between Saussurea involucrate treated group and ulinastatin groups (7.56±0.88,(2 607.0±239.0) U/L,(252.2 ±9.2) ng/L,(443.4±9.6) ng/L,(308.4±9.2) mmol/L,2.10±0.12,1.74±0.04,(26.00±3.67)％,(134.5±7.8) ng/L and 1.42±0.06) at 48 hours (all P＞0.05).Conclusion Saussurea involucrate injection can eliminate oxygen free radicals and prevent to xidation,inhibit NF-κB activation,regulate synthesis and release of cytokines,and alleviate pancreatic injury in SAP rats,but it can not decrease mortality.
