Objective To evaluate if the assay of platelet-associated immunoglobulin G (PAIgG) can improve the sensitivity of monoclonal antibody immobilization of platelet antigens assay (MAIPA) in immune thrombocytopenic purpura (ITP).Methods Anti-GP Ⅱb/Ⅲa and anti-GP Ⅰb/Ⅸ autoantibodies were detected by a modified MAIPA;PAIgG was detected by competitive ELISA.MAIPA and PAIgG were done simultaneously in 190 patients with thrombocytopenia,in which 132 were diagnosed as ITP according to the diagnostic criteria Kappa test was used to analyze the concordance between MAIPA and PAIgG.Results The sensitivities of PAIgG alone or in parallel with MAIPA to ITP were 32.6% and 37.2% higher than MAIPA alone respectively,while their specifieities were 51.7% and 56.9% lower respectively.The sensitivity,specificity,positive predictive value,negative predictive value of PAIgG in series with MAIPA were all not superior to MAIPA alone.The kappa values between MAIPA and PAIgG in ITP and non-immune thrombocytopenia were 0.129 and 0.012 respectively,which meant the concordance between them was poor.Conclusion The detection of PAIgG should not be used as screening before MAIPA in distinguishing immune from non-immune thrombocytopenia.

Objective To explore the effects of coincident infection on treatment response and coronary artery lesion (CAL) outcome in children with Kawasaki disease(KD).Methods A retrospective study of 141 children diagnosed on KD between Jul.2005 and Dec.2006 were performed.Standardized clinical assessments,laboratory examinations microbiology test results plus treatment regimens were reviewed.CAL were visualized by using echocardiography.Infectious agents positive (INF+) and negative (INF-) groups were identified,and clinical assessments,laboratory and treatment data were analyzed.Results 1.Concurrent infections:41%(58/141) of children had one of above confirmed infection at KD diagnosis.2.Treatment response:the presence of infection did not alter the response to treatment with intravenous immunoglobulin (IVIG),with resolution of fever within 72 h in 85% (120/141) children after 1 dose of IVIG (2 g/kg) together with aspirin administration regardless of present or absent infection.3.CAL outcome:in total,56.0% (79/141) of children developed CAL at the time of diagnosis,involving dilatation (91.1%,72/79 cases) and aneurysm (8.9%,7/79 cases),and no giant aneurysm was found.Most CAL were recovered within 1 year after treatment.Incidence of aneurysm in INF+ group was significantly higher than that in INF-group (P=0.019).Conclusions Coincident infection would not affect on the clinical assessment,laboratory test results and treatment response to IVIG in children with KD,but would result in higher risk of serious CAL.Therefore,children with infection at diagnosis on KD will not only accept active treatment in acute phase,but also insist on convalescent care and follow-up visit.

OBJECTIVEParkinson's disease (PD), a neurodegenerative disorder, has been reported to be associated with brain neuroinflammation in its pathogenesis. Herein, changes in peripheral immune system were determined to better understand PD pathogenesis and provide possible target for treatment of PD through improvement of immune disorder.

METHODS1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) was intraperitoneally injected into mice to prepare PD model. Expression levels of pro-inflammatory and anti-inflammatory cytokines and transcription factors of CD4+ T lymphocyte subsets in spleen and mesenteric lymph nodes and concentrations of the cytokines in serum were examined on day 7 after MPTP injection. Percentages of CD4+ T lymphocyte subsets were measured by flow cytometry.

RESULTSMPTP induced PD-like changes such as motor and behavioral deficits and nigrostriatal impairment. Expression levels of the pro-inflammatory cytokines including interferon (IFN)-γ, interleukin (IL)-2, IL-17 and IL-22, in spleen and mesenteric lymph nodes were upregulated and their concentrations in serum were elevated in PD progression. But, the concentrations of the anti-inflammatory cytokines including IL-4, IL-10 and transforming growth factor (TGF)-β were not altered in the two lymphoid tissues or serum of PD mice. In addition, expression of T-box in T cells (T-bet), the specific transcription factor of helper T (Th) 1 cells, was downregulated, but expression of transcription factor forkhead box p3 (Foxp3), the transcription factor of regulatory T (Treg) cells, was upregulated. In support of the results, the numbers of IFN-γ-producing CD4+ cells (Th1 cells) were reduced but CD4+CD25+ cells (Treg cells) were elevated in both the lymphoid tissues of PD mice.

CONCLUSIONPD has a dysfunction of peripheral immune system. It manifests enhancement of proinflammatory response and CD4+ T cell differentiation bias towards Treg cells away from Th1 cells.

OBJECTIVEWe used an animal model of collagen-induced arthritis (CIA) to study changes and roles of tyrosine hydroxylase (TH) expressed by CD4+ T cell subsets, and then explore the relationship between CD4+ T cell subset-derived catecholamines and inflammatory responses in CIA.

METHODSThirty-six male DBA/1 mice were randomly divided into control group, CIA model group (day 35) and CIA model group (day 55) (n = 12). CIA model was induced by type II collagen (CII) in DBA/1 mice. On the 35th and 55th day following primary immunization, the joints of the mice were observed for clinical score of swelling and the level of anti-CII IgG antibody in serum was examined. Expression of specific transcription factors and cytokines of Th1, Th17, Th2 and Treg cells and TH in mesenteric lymph nodes was measured by means of Western blot. The changes of TH expressed by CD4+ T cell subsets in mesenteric lymph nodes were determined by flow cytometry.

RESULTSClinical score and anti-CII antibody level increased in CIA compared with that in intact mice. Specific transcription factors and cytokines expressed by Th1 and Th17 cells were upregulated and cytokines expressed by Th2 and Treg cells were downregulated in mesenteric lymph nodes in CIA mice. Expression of TH was upregulated and the increased expression of TH in CD4+ T cells was attributed to Th1 and Th17 cells in mesenteric lymph nodes of CIA.

CONCLUSIONThe increase in catecholamines from CD4+ T cell subsets in mesenteric lymph nodes of CIA may be related to inflammatory alleviation in CIA progression.

OBJECTIVETo evaluate the efficacy and safety of Jinying Capsule (JC) in treating pelvic inflammatory disease patients with accumulated damp-heat syndrome (ADHS).

METHODSTotally 328 patients were recruited in a prospective, positive drug parallel controlled, and multi-center clinical trial. Of them 213 patients in the treatment group took JC (0.5 g per capsule), 4 capsules each time, 3 times per day, while 115 patients in the control group took Kangfuyan Capsule (KC, 0.4 g per capsule), 3 capsules each time, twice per day. The course of treatment was 4 weeks for all. Scores of Chinese medical syndromes, visual analogue scale (VAS) of the lower abdominal pain, and European quality of life-five dimension scale (EQ-5D) were observed before treatment and after 4 weeks of treatment.

RESULTSThere were 204 patients in the treatment group and 109 in the control group who completed this trial. The total effective rate of Chinese medical syndrome was 89.71% (183/204 cases) in the treatment group and 76.15% (83/109 cases) in the control group (P < 0.01). Compared with before treatment in the same group, EQ-5D scores increased, and VAS scores of the lower abdominal pain decreased in the two groups after treatment. EQ-5D scores was 0.857 ± 0.157 in the treatment group, obviously higher than that in the control group (0.753 ± 0.126, P < 0.05). VAS scores of the lower abdominal pain was 2.14 ± 1.23 in the treatment group, lower than that in the control group (2.33 ± 1.24), but with no statistical difference between the two groups (P > 0.05). No adverse reaction occurred in the two groups.

CONCLUSIONJC was superior to KC in improving Chinese medical syndrome and quality of life of pelvic inflammatory disease patients with accumulated damp-heat syndrome.

Objective: To investigate the characteristics of traditional Chinese medicine (TCM) syndromes and their elements in patients with posthepatitic cirrhosis by analyzing the relationships between signs and symptoms and biochemical parameters. Methods: A total of 440 patients with hepatitis B cirrhosis treated in Shanghai Public Health Center and Shuguang Hospital, Longhua Hospital and Central Hospital of Putuo District Affiliated to Shanghai University of Traditional Chinese Medicine during January 2002 to January 2006 were enrolled in this study. Signs and symptoms and biochemical information of patients were collected by using a self-designed questionnaire regarding the four examinations of TCM. Signs and symptoms were firstly analyzed to find the frequency of occurrence. Then, the patients were divided into two groups according to non-existent or existent sign and symptom and the correlations between the signs and symptoms which occurred most frequently and their biochemical parameters were analyzed. Results: Sixteen symptoms which occurred most frequently were fatigue, colored urine, liver palms, opaque complexion, string-like pulse, weakness at waist and knees, dry month and bitter taste in the mouth, profuse dreaminess and poor sleepiness, heaviness of limbs, abdominal distention, yellow eyes, fine pulse, impetuosity and susceptibility to rage, splenomegaly, poor appetite, and distension and fullness in the chest and hypochondrium. A previous study on syndrome differentiation of 900 patients with posthepatitic cirrhosis showed 4 syndrome patterns: internal accumulation of dampness-heat, liver-kidney yin deficiency, internal accumulation of blood stasis-heat, and liver depression and spleen deficiency. Further analysis showed that internal accumulation of dampness-heat syndrome was characterized by obvious hepatic inflammation, poor synthesis function and more asctites. Liver-kidney yin deficiency syndrome was characterized by low-level hepatic inflammation, poor synthesis function and more ascites. Internal accumulation of blood stasis-heat syndrome was characterized by low-level hepatic inflammation, poorer synthesis function, ascites and splenomegalia, and liver depression and spleen deficiency syndrome was characterized by slight hepatic inflammation, synthesis function injury, decreased internal portal vein diameter and less ascites. Conclusion: Different syndrome patterns have different pathological features, showing the complexity and polymorphism of syndrome construction.
