Objective :To study the significance of anticardiolipin antibodies (ACA) in patients with lupus nephritis( LN). Methods : We detected serum ACA in 32 cases of LN. The control group consisted of 28 healthy cases. We observed the relation between the levels of ACA and the levels of clinical biochemical index. Results :The positive rate of IgG- ACA, IgM- ACA IgA- ACA was 53. 1%, 40. 6% ,46. 9% in patients with LN. In patients with positive ACA, lower levels of hemoglobin , thrombocytopeinia and C3 were observed as well as elevated levels of serum IgG,24h- urine protein, antinuclear antibody titer and serum creatinine(P

0.05).Conclusion:LEF is an effective agent for treatment ofRA with better tolerability,and there are few adverse effects.

Objective:To explore the underlying molecular mechanisms of specific cyclooxygenase-2 inhibitor(Rofecoxib)and to evaluate its efficacy on MRL/lpr mice.Methods:12-week female MRL/lpr mice were given Rofecoxib (10mg?kg -1 ?d -1 )for 12 weeks.Suppressive effect of the drugs on serum and urinary levels of tumor necrosis factor-?(TNF-?),interleukin-6(IL-6) and urinary TXB 2 level were determined by using radio-immunological assay.Changes in proteinuria,serum creatinine,pathology of ltidney and the expression of CD14 in renal tissues were observed.Results:Compared with the ones in the control group,mice treated with Rofecoxib had lower levels of proteinuria( P

0.05).The levels of serum anti-MPO antibody in patients with lupus nephritis(LN)and purpuric glomerulonephritis had significantly increased(P

Objective To investigate the clinical effect of live combined bifidobacterium,lactobacillus and enterococcus powder (probiotics bifico) treatment in children with secondary diarrhea of pneumonia and analysis of related factors.Methods Three hundred and eighty-five pneumonia children were studied.The related factors of secondary diarrhea of pneumonia were screened.One hundred and twenty cases of children with secondary diarrhea of pneumonia were divided into observation group and control group by table of random digit with 60 cases each.The observation group was given the probiotics bifico combined with conventional treatment,the control group was given the conventional treatment.The clinical efficacy was evaluated treatment after 7 d.Results The effective rate of observation group was significantly higher than that of control group [96.7％(58/60) vs.61.7％(37/60),x2 =22.282,P＜ 0.01].Age of onset,hospitalization time,invasive procedures,combination therapy of antibiotics,therapy of hormone and therapy of probiotics bifico were related with the incidence of secondary diarrhea of pneumonia (P ＜ 0.01 or ＜ 0.05).Conclusions The younger children,long hospital stay,invasive procedures,combination therapy of antibiotics and therapy of hormone are the risk factors of secondary diarrhea of pneumonia.The probiotics bifico for treating the children with secondary diarrhea of pneumonia has exact clinical efficacy,and it is worthy of clinical application.

Objective To study the value of B-cell activating factor (BAFF) expression levels in the diagnosis and prog-nosis of children with idiopathic thrombocytopenic purpura. Methods Children with idiopathic thrombocytopenic purpura (ITP) admitted to our hospital from September 2011 to September 2013 were enrolled in observation group, and healthy check-up chil-dren during the same period were enrolled as controls. The serum levels of B-cell activating factor, platelet antibodies (PAIgG, PAIgM, PAIgA) and platelet count were detected, and curative effect in children with ITP was observed. Results The BAFF, PAIgG, PAIgM and PAIgA levels were higher and platelet count were less in both acute and chronic ITP children than those in normal controls. The difference was signiifcant (P<0.05). The results of linear regression analysis indicated that BAFF levels were positively correlated with PAIgG, PAIgM and PAIgA levels (β=1.87~2.25, P<0.05), and were negatively correlated with platelet count (β=-2.42, P<0.05). Meanwhile, BAFF levels were negatively correlated with curative effect in ITP children (β=-1.88, P<0.05). When the value of BAFF was 1.35, the sensitivity for predicting effective treatment was 0.84 and the speciifcity was 0.75. The area under the ROC curve was 0.85 (95%CI:0.73~0.98, P=0.000). Conclusions The serum BAFF expression was increased and closely related to the level of antiplatelet antibody, platelet count and treatment effect in ITP children, and therefore, was a good indicator for the diagnosis and prognosis of ITP.

Objective To evaluate the effect of small dose ketamine on the efficacy of intravenous PCA (POA) with sufentanil after intra-abdominal surgery in aged patients.Methods Sixty ASA Ⅰ orⅡpatienm aged 65-82 yr undergoing elective intra-abdominal surgery under general anesthesia were randomized into 3 groups (n=20 each)according to the composition of PCIA solution:group I sufentanil 200 μg in 200 ml of noilnal saline (group S);group μ sufentanil 200μh+ketmine 100 mg in NS 200 ml(group K1)and group Ⅲ sufentannil 200 μg+ketmine 200 mg in NS 200 ml(group K2).A loading dose of 5 ml wag given at the end of operation.The PCIA setting was as follows:backgound infusion 1 ml/h,bolus dose 2 ml,lockout interval 5 min and 4-hour maximum dose 30 m1.If VAS score(0=no pain,10=womt pain)was≥7,pethidine 25 mg was given iv.The total amount of pethidine given within 48 h after operation and postoperative complications including nausea and vomiting and respiratory depression were recorded.Results Small dose ketamine added to the PCIA solution can significantly reduce the amount of pethidine administered after operation in a dose-dependent manner.Conclusion Small dose ketamine can improve the efficacy of PCIA with sufentanil after intra-abdominal surgery in aged patients with no significant adverse effect.

Objective To explore the clinical significance of osteopontin (OPN) in systemic lupus erythematosus (SLE) and its pathogenic role in SLE by studying the correlation between OPN and clinical manifestations,laboratory parameters and disease activity.Methods The enzyme-linked immunosorbent assay(ELISA)was used to measure the level of OPN in serum of 68 SLE patients and 20 healthy controls.the clin-ical data and laboratory parameters were recorded.Results The positive rate of OPN was 79.41%in 68 SLEpatients and could not be detected in healthy controls.Compared with healthy controls.the positive rate and level of OPN in SLE patients was significantly higher(P＜0.01).There was no significant difference in age.gender and disease duration between OPN positive and negative lupus patients(P＞0.05).The Drevalence of fever,hair loss,WBC decrease,liver damage,serum C4 decrease,proteinuria and anti-dsDNA antibody in OPN positive SLE were significantly higher than those of OPN negative SLE(P＜0.05).The positive rate of serum OPN in SLE patients was significantly higher than that of anti-dsDNA antibody and anti-Sm antibody (P＜0.01).The level of plasma OPN was associated with systemic lupus erythematosus disease activity index (SLEDAI)(r=0.292,P＜0.05).The positive rate and level of OPN in active SLE patients was significantly higher than that of inactive SLE patients(P＜O.05).Conclusion The level of plasma OPN has a close rela-tionship with the activity of SLE.It may serve as an active disease marker of SLE.
