The diversity of diagnostic criteria of idiopathic thrombocytopenic purpura (ITP) makes it difficult to compare clinical trial results and exchange clinical experiences. To address this issue, an ITP international working group convened a consensus conference in Italy in October 2007, and some new consensus concerning the terminology, definition, phases, grading of severity, prognosis, and treatment were achieved. The treatment of ITP has been dramatically improved along with the introduction of novel therapeutic agents. Rituximab, a monoclonal anti-CD20 antibody that is able to deplete autoantibody-producing B lymphocytes, has been widely applied because of its high efficacy and safety. Recent evidences suggest that decreased platelet production may also contribute to the development of ITP. Therefore, novel thrombopoiesis-stimulating agents such as thrombopoietin-receptor agonists Romiplostim and Eltrombopag have become new therapeutic options for ITP.

Objective To investigate clinically applied value of P300 with influential factors in olivopontocerebellar atrophy (OPCA). Methods The P300 and cognitive ability sifting investigation (CASI) were tested in 34 OPCA cases and normal controls with equal age, gender and educational levels. Results The P300 latency was significantly longer in OPCA group of different ages than that in the normal control group (P

Flavones and flavonols belong to flavonoids that have anti-cancer activities. In order to explore molecular mechanism and inhibitory effects of flavones and flavonols on human esophageal carcinoma cells, the inhibition of proliferation and the induction of G2/M cell cycle arrest in KYSE-510 cells and OE33 cells treated with three flavones (luteolin, apigenin, chrysin) and three flavonols (quercetin, kaempferol, myricetin) were analyzed by MTT array and flow cytometry. Among these compounds, luteolin and quercetin were the most active flavonoid to inhibit the proliferation of KYSE-510 cells and OE33 cells, respectively. The genes related to cell cycle control were analyzed by gene chip, after KYSE-510 cells and OE33 cells were treated by luteolin and quercetin, respectively. The results were shown that the expression of p21waf1 was induced and the expression of cyclin B1 was suppressed in KYSE-510 cells, and that the expression of GADD45? and 14-3-3? were induced and the expression of cyclin B1 was suppressed in OE33 cells. These results were verified by real-time RT-PCR and Western-blot. The comparative effects of all six compounds on the regulation of these gene expressions at the mRNA and protein levels were also analyzed by real-time RT-PCR and Western-blot. The results were shown that p21waf1, GADD45?, 14-3-3? and cyclin B1 were the target genes which mediated the effects of flavones and flavonols on induction of cell cycle arrest in KYSE-510 cells and OE33 cells.

Two human esophageal cancer cell lines (KYSE-510 and OE33) were chosen as the tumor model to explore molecular mechanism of flavones and flavonols on induction of apoptosis. Effects of flavones (luteolin, apigenin, chrysin) and flavonols (quercetin, kaempferol, myricetin) on induction of apoptosis in KYSE-510 cells and OE33 cells were observed by DNA fragmentation, acridine orange staining and flow cytometry analysis. The results of real-time RT-PCR and Western-blot analysis showed that the treatment of KYSE-510 cells and OE33 cells with flavones and flavonols induced the expression of PIG3 at the mRNA and the protein levels. Western-blot analytical results further showed that induction of PIG3 caused apoptosis in both esophageal cancer cells through the mitochondrial pathway in a p53-independent manner, and p63 and p73 may be responsible for the induction of PIG3.

By means of the observation of acridine orange-stained lysosomes with fluorescence microscope, we studied the intracellular killing and digestive process after alveolar macrophage (AM) ingested living-yeast. Based on the morphological changes of the cells, we divided the process into three stages: the pre-phagosome-lysosome fusion stage, the phagosome-lysosome fusion and killing stage, and the digestive stage. The results revealed that all the values of phagocytic index, phagocytic rate, fusion index and fusion rate of the isolated AM of rabbits infected with living-BCG were higher than those of normal rabbits (P

Objective Though X-ray measurement of metacarpal bones of right hand in children aged 7-12 in Kaschin-Beck disease (KBD) endemic areas in Xinghai County,Qinghai Province,to provide scientific basis for KBD diagnosis and research on growth and development of children in KBD endemic areas.Methods In 2012,277 children aged 7-12 were carried out clinical examination and right hand X-ray photos in KBD endemic areas,Xinghai County,Qinghai Province.Metacarpal bones were measured by electronic digital vernier caliper,and the axis length and width of the metacarpal bones and its metacarpal bone index were calculated.All data were analyzed by SPSS 19.0 software.Results The axis lengths of the metacarpal bones were in an order of 2.metacarpal ＞ 3.metacarpal ＞ 4.metacarpal ＞ 5.metacarpal ＞ 1.metacarpal in 6 different age groups and different genders; the width of 1.metacarpal bone was the widest; the width of 4.metacarpal bone was the smallest,and the rest of metacarpal bones were similar.The metacarpal bone indexes of female [(7.96 ± 0.76),(8.24 ± 0.92),(8.24 ± 0.71),(8.26 ± 0.92),(8.60 ± 1.02),(8.67 ± 0.84)mm] were higher than those of male's[(7.30 ± 0.78),(7.53 ± 0.77),(7.98 ± 0.90),(7.79 ± 0.56),(7.96 ± 0.64),(8.17 ± 0.92)mm,F =4.302,P ＜ 0.05].Conclusion The axis length,width and index of metacarpal bones of right hand in children between KBD endemic areas and no-KBD endemic areas are similar.

In recent years, the incidence of pediatric malignancies has gradually increased. High-risk patients have poor prognosis, and the main effect of treatments such as surgery and radio-chemotherapy has reached a plateau phase. Targeted therapy, with its reliable efficacy and mild toxicity, has become one of the most promising approaches. Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase, and its abnormal forms include gene fusion, gene mutation, gene amplification, and protein overexpression. These aberrations play important roles in the development of childhood cancer. With the application of ALK inhibitors in clinical anti-tumor therapy, targeted ALK treatment has received increased attention. This article aims to review various studies on the relationship between ALK aberrations and pediatric malignancies.

Objective To investigate the risk factors of progressive intracerebral hematoma (PIH) in severe traumatic brain injury (STBI) and provide reference for diagnosis and treatment of STBI.Methods The clinical information of 96 patients of STBI from March 2008 to March 2012 were retrospectively analyzed,the risk factors of PIH were analyzed by the univariate and multivariate Logistic regression analysis.Results Thirty-six patients occurred PIH,the incidence rate of PIH was 37.5％ (36/96).The univariate regression analysis showed that the age,admission GCS scores,injury to the first CT time,brain contusion,subarachnoid hemorrhage,epidural hematoma,subdural hematoma had certain relation with PIH (P ＜ 0.01or ＜ 0.05).Multivariate Logistic regression analysis showed that the age,brain contusion,subarachnoid hemorrhage,epidural hematoma,subdural hematoma were risk factors of PIH (P ＜0.05 or ＜0.01).Conclusion Fully aware of the risk factors of PIH and timely intervention is the key to reduce the morbidity and mortality of STBI.
