Chronic refractory autoimmune thrombocytopenia (C/RITP) comprises complex and heterogeneous pathogenesis.Beyond the classic immune disorders such as platelet autoantibodies and cellular immune imbalance,other important considerations that can cause acquired C/RITP include infection,drug,vaccines,autoimmune diseases,tumor,or platelet function disorder.In addition,advances in the molecular mechanism and genetic correlations of C/RITP for children are also discussed.

Objectives To determine the serum levels of high mobility group box-1 protein ( HMGB1 )in patients with acute pancreatitis (AP) and to investigate the contributions of HMGB1 in the pathogenesis of AP. Methods The serum HMGB1 concentrations were determined by enzyme-linked immunosorbent assay in 33 patients with severe acute pancreatitis (SAP), 38 patients with mild acute pancreatitis (MAP) and 28 healthy controls at the time of admission within 72 h after the onset. THe relationships between the serum HMGB1 levels and sex, age, etiology, disease onset, Ranson score, Balthazar CT score, C-reactive protein,lactate dehydrogenase and serum creatinine, total bilirubin levels, local and systematic complications were analized. Results The serum HMGB1 levels in healthy control group, MAP group and SAP group were ( 1.82 ±0.64)μg/L, (6. 13 ±5.80) μg/L and (11.48 ±6.94)μg/L, respectively. The mean value of serum HMGB1 level in MAP group was significantly higher than that in healthy group ( P < 0. 05 ), while it was significantly lower than that in SAP group ( P <0.05 ). Within 24 h after disease onset, the serum levels of HMGB1 began to increase, and reached the peak at 48 h, then decreased and remained higher than normal value at 72 h.There were no remarkable relationships between the serum HMGB1 levels and sex, age, etiology, but it was positively correlated with Ranson score, Balthazar CT score, C-reactive protein, lactate dehydrogenase and serum crkatinine. The serum levels of HMGB 1 in patients with local and / or systematic complications were higher than those in patients without complications, but the difference was not statistically significant.Conclusions HMGB1 is a late inflammation mediator and serum HMGB1 levels were correlated with the severity of AP. HMGB1 may participate in the development of acute renal insufficiency during SAP.

Objective To explore the factors of medical anthropology related to malaria control among Wa Ethnic minority in Ximeng County, Yunnan Province. Methods The study was conducted by the combination of anthropology and epidemiology, qualitative and quantitative, statistical analysis and description. Results Wa people considered malaria as one of three major diseases in the community. In Wa Ethnical language, the word of malaria, “Saihui” (Sai-illness and pain, Hui-being attacked quickly), does not mean of fever. About one third of Wa people had not thought fever as one of malaria symptoms. Most of Wa people only knew vivax malaria, but not falciparum malaria. Only 32.7% of people could connect malaria with mosquitoes, and a few of them could confirm mosquitoes as the only malaria vector. The proportions of sound knowledge of malaria causes, prevention and treatment seeking assessed were lower than 25.0%. As a result of multivariate logistic regression, 3 kinds of malaria knowledge were closely correlated each other, and the connection between causal knowledge and prevention (adjusted OR: 36.610, 95%CI: 10.242-130.866, P

Cognitive behavior therapy (CBT) has been proved to be an effective psychological treatment method for depression,especially for mild-to-moderate depression,however,due to the influence of various factors,its application in patients with depression is limited.Studies abroad have confirmed self-help intervention based on CBT has good effects on patients with depression.By reviewing efficacy of self-help interventions based on CBT on depression,it can be known that most of the literatures support that self-help interventions based on CBT has good effects on depression.Related researches abroad have been more mature,but few similar studies have been conducted in our country.So self-help CBT for depression has broad prospects in our country,which can play an important role in the prevention and therapy of depression,alleviating the shortage of medical resources,and reducing the patients' medical expenses,etc.Based on bibliotherapy (a major form of self-help interventions based on CBT),future studies need to learn from foreign practice to expand the audience to the clinic,community and non-clinical patients,in order to provide advice for interventions for depression in China.

Objective To study the effects of anthocyanins on hepatic lipid accumulation and to explore the possible mechanisms. Method HepG2 cells were treated with 1,10 and 100 ?mol/L cyanidin-3-0-?-glucoside (Cy-3-g) for 1h,carnitine palmitoyl transferase-I (CPT-I) protein level and acetyl CoA carboxylase (ACC) phosphorylation,triglyceride,fatty acid oxidation,the activity of AMPK,AMPK and p-AMPK protein levels were evaluated. Results Compared with the control,the treatment of HepG2 with 1,10,100 ?mol/L Cy-3-g resulted in significant decrease of intracellular triglyceride,and significant increase of CPT-I protein,and AMPK activity and phosphorylation. However,there were no differences in AMPK protein level among all groups. The treatment of 100?mol/L Cy-3-g promoted the fatty acid oxidation in HepG2. The treatment of 10,100 ?mol/L Cy-3-g significantly increased ACC phosphorylation. Conclusion Anthocyanin Cy-3-g could attenuate hepatic lipid accumulation in HepG2. The mechanism may result from the regulation of the AMPK-ACC-CPT-I signal pathway and promotion of fatty acid oxidation.

Aim This was to study the effects of hydroxysafflor yellow A(HYSA)on iNOS expression in rats following focal cerebral ischemia. Methods Rat cerebral ischemia-reperfusion injury was induced by middle cerebral artery occlusion. The expression levels of iNOS were examined using immunohistochemical method. The neurological outcome and the cerebral infarct area were evaluated. Results The expression levels of iNOS in HYSA groups were significantly lower than those in ischemic model group. Treatment with HYSA also decreased the cerebral infarct area and the neurological deficit score. Conclusion HYSA induced down regulation of iNOS expression, which may mediate the protective effect of HYSA on cerebral ischemia.
