Background Researches showed that multifocal electroretinogram (mfERG) is able to assess the retinal function in the eyes with acute Vogt-Koyanagi-Harada ( VKH ) syndrome. But the mfERG characteristics of convalescence stage of VKH are still below clear. Objective Present study was to compare and follow up the variation process of visual acuity and mfERG in acute and recovery stages of VKH syndrome. Methods This was a clinic-based retrospective study. Visual acuity, mfERG and fundus fluorescence angiography ( FFA ) were recorded from 35 eyes of 18 acute VKH cases. The period of follow-up in recovery stage lasted about 18 months with the repetitive recording results for 4 times. Results In this study, the visual acuity range in acute stage VKH was 0. 01 to 1.0, and 91.4% (32/35 eyes) was below 0.6. Compared with normal control group, the visual acuity was significantly decreased (P＜0.01). The response densities (amplitudes) of N1 ,P1 waves of the first-order kernel were significantly lowed in all the 6 rings,and the implicit times of 1-4 rings of both waves were significantly prolonged in acute VKH eyes(P＜0. 05). The abnormalities of retinal function showed a regional difference at the posterior pole retina with the dominant change in the first ring,showing a cutting off78% in the P1 amplitude. The abnormal degree of mfERG was more serious as the the increase of retinal eccentricity. In 2 months of convalescence after glucocorticosteroids therapy,the range of visual acuity were 0. 1-1.2 ,and the amplitudes of N1, P1 of 1-2 rings were greatly elevated in comparison with acute on-set (P＜0. 05 ). However, there was still a remarkable difference in the amplitudes of from 1 through 6 rings,comparing with normal. The response density of P1 wave from whole recording region was only 44% of normal. Though the visual acuity was stable during the follow-up duration, a decreasing tendency in N1 and P1 amplitudes were seen. The implicit times of both wave shortened only in 1-3 rings in recovery stages of VKH (P＜0.05). Conclusion VKH syndrome cause serious damage of posterior retinal function.Macular region is the site with greater retinal functional lesion and restore before and after medication. This hardly recovery of retinal function can last over one and half year,even satisfied visual acuity is stable after proper treatment.

·AIM: To investigate the preparation of endostatin protein and its biologic activity on vascular endothelial cell.· METHODS: pBlast-hEndostatin and pBlast-Mcs were identified by digesting with Nhe Ⅰ and Sal Ⅰ, by PCR reaction, by sequencing, and by Alignments of PCR products with gene bank using NCBIBLAST software. The identified pBlast-hEndostatin as well as pBlast-Mcs were then purified with QIAGEN Endofree plasmid maxi kit.The purified plasmids transfected human fibroblasts. The expression of endostatin was detected by RT-PCR, Westem-Blot and immunohistochemistry. The endostatin prorein produced by transfected fibroblasts was purified by ultrafiltration and affinity chromatography. The inhibitory action of endostatin on human umbilical vein endothelium was measured by MTT assay.· RESULTS: pBlast-hEndostatin was found to contain human endostatin gene. Endostatin protein was produced by transfected fibroblasts. The inhibitory ratio of 2.5,5,10,20,40,80mg/L endostatin on human umbilical vein endothelium for 48h were 8.5%,13.1%,27.7%,38.1%,56.7%,63.8% respectively. IC50 value was 34.5mg/L.No inhibition action was found on fibroblasts.·CONCLUSIONS: Endostatin protein can be produced by the transfected fibroblasts. The produced endostatin has inhibitory action on human umbilical vein endothelium and has no inhibition action on fibroblasts.

Quantum dots(QDs) are semiconductor nanocrystals composed of element from the periodic groups of II(-IIIIII( or III(-IIIII(, which possess wide excitation spectra and narrow emission spectra. The maximum emission wavelength of QDs can be controlled in a relatively simple manner by variation of particle size and composition. QDs can be tuned at a variety of precise wavelengths from ultraviolet(UV) to near infrared(NIR). QDs can be conjugated to a wide range of biological targets, including monoclonal antibodies, proteins, polymers and nucleic acid probes. These characteristics make it not only for revealing interaction of nucleic acids, proteins and other biological macromolecules, by biological imaging but also for detection of lymph node metastasis through preoperative and introperative lymphatic imaging. Along with the continuously improvement of observation techniques and quantum dot structure optimization in recent years, the research on lymph node imaging is ongoing.

OBJECTIVETo summarize the clinical characteristics of secondary coagulation disorders caused by exposure to poison (raticide) in children and to investigate the diagnosis and corresponding treatment.

METHODThe process of diagnosis, clinical characteristics, response to treatment and the prognosis were analyzed.

RESULTSThe main clinical manifestation was mucosal bleeding (66.6%), including epistaxis, gingival bleeding, hematomas and so on. All these children were previously well and had no history of bleeding. Activated partial thromboplastin time (APTT) and prothrombin time (PT) were prolonged, factor II was undetectable and the levels of factors VII, IX, and X were lower. The fibrinogen was normal. A raticide was detected in blood and urine of 13 children although 12 of the patients had no definite history of raticide ingestion. Prothrombin complex, fresh frozen plasma and vitamin K(1) were effective in these cases. However, 2 - 3 weeks later, 6 patients presented with recurrent bleeding.

CONCLUSIONFor children with secondary coagulation disorders of unknown cause, intoxication of raticide should be considered. The administration of blood coagulation factors and vitamin K(1) are effective in early treatment, and the treatment period should be more than 2 months. The PT and APTT should be followed up. Vitamin K(1) should be stopped when PT and APTT are normal.

OBJECTIVETo summarize the clinical characteristics, laboratory findings and prognosis of patients with Down syndrome-related acute leukemia (DS-AL).

METHODSThe clinical data, laboratory findings, chemotherapy and prognosis of 21 children with DS-AL were analyzed.

RESULTSMost of the children had disease onset of leukemia at 1 to 5 years of age (85.7%), and acute myeloid leukemia accounted for 57.1% of these cases; 61.9% of the patients had increased lactate dehydrogenase level by 2 folds or more. Of the 13 cases undergoing echocardiaography, 10 (67.9%) showed abnormal findings, and complex congenital heart disease was common (38.5%). Six of the children received chemotherapy and complete remission was achieved in 4 cases; 2 patients died of infection, and the treatment-related mortality was 33.3%. The 2 patients receiving reduced intensive chemotherapy have so far had event-free survival for 21 and 43 months.

CONCLUSIONAcute myeloid leukemia is the most common subtype of DS-AL. Patients with DS-AL are sensitive to chemotherapy and the prognosis was favorable with reduced intensive chemotherapy.

Objective: To investigate the characteristics and prognostic factor of central nervous system (CNS) involvement in patients with hemophagocytic lymphohistiocytosis (HLH) . Methods: From January 2006 to October 2015, 152 patients with HLH, 88 patients had CNS involvement, their clinical data were collected, and survival was analyzed using the Kaplan-Meier life table method, univariate and multivariate Cox regression model analyses were applied to identify the risk factors of prognosis. Results: ①57.9% patients complicated with neurological symptoms, cerebrospinal fluid abnormalities were observed in 37.0% patients, 57.5% patients had abnormal neuroradiology. ②36 patients survived well, 3 patients lost to follow-up, 49 dead, 1 survival patient had epilepsy. ③The 3-year overall survival rate of 88 patients was 44%. ④abnormal CSF and unreceived IT bore a significant, independent adverse prognostic value (P<0.05) . Conclusion CNS involvement in HLH has a high frequency and poor prognosis, few patients remained neurologic sequelae; abnormal CSF related to poor prognosis, positive intrathecal injections could improve the prognosis.

OBJECTIVEThe Chinese Children's Leukemia Group (CCLG)-acute lymphoblastic leukemia (ALL) 08 protocol for childhood ALL was established in 2008. This study aims to evaluate the drug-related toxicities of CCLG-ALL 08 protocol in the treatment of childhood ALL.

METHODSA total of 114 children with newly diagnosed ALL were treated with the CCLG-ALL 08 protocol. The protocol was divided into five phases: remission induction (VDLD), early reinforcement (CAM), consolidation therapy, delayed reinforcement (DIa & DIb) and maintenance treatment. Drug-related toxicities in each phase were evaluated according to the Common Terminology Criteria for Adverse Events version 4.0.

RESULTSToxicities were more frequent in phase VDLD than other treatment phases, including hepatotoxicity (87.7%), dental ulcer (20.2%), hyperglycemia (20.2%), prolonged activated partial thromboplastin time (21.1%) and decreased fibrinogen (34.2%), with the incidence rates of severe adverse events at 7%, 0, 1.3%, 0.8% and 2.7% respectively. The incidence of allergic reaction to L-ASP was significantly higher in phase DIa than in phase VDLD (28.0% vs 7.9%; P<0.01), and there were no longer any allergic reactions in 15 patients who received continuing treatment with pegaspargase instead. There was no severe arrhythmia, myocardial ischemia, decreased left ventricular function, osteonecrosis, myopathy, organ failure or treatment-related mortality.

CONCLUSIONSThe drug-related toxicities of CCLG-ALL 08 protocol are common in phase VDLD, but they are mild and reversible. There is no treatment-related mortality. The CCLG-ALL 08 protocol for childhood ALL is safe.
