Objective:To investigate the effects of IL-12p35 small interference RNA on immune functions of Dendritic cells in rats.Methods:DCs were generated by culturing bone marrow progenitor cells of rats with GM-CSF, IL-4 and LPS in vitro. The IL-12p35 siRNA was synthesized and transfected into DCs. The expressions of CD80 and MHCⅡwere examined by flow cytometry. Reverse transcriptase PCR analysis was used to detect IL-12p35 mRNA transcription and ELISA was used to detect IL-12 and IL-10 protein levels, respectively. The antigen presenting by DCs was evaluated by mixed lymphocyte responses.Results:IL-12p35 siRNA silenced DCs expressed lower IL-12, higher IL-10,and exhibited weak activity in stimulating the proliferation of allogenic T cells, but no changes on CD80 and MHCⅡexpressions.Conclusion:IL-12p35 siRNA interference exerts no effects on maturation of DC, but negative effect on immume function of DCs.

Objective To summary the clinical characteristics of epileptic spasm(ES)that is the unique form of seizures in childhood. Methods A total of 149 patients with ES who visited our hospital from May 2009 to June 2015 were collected. The documents of clinical data, treatment and outcome were analyzed retrospectively. The statistical analysis of some clinical characteristics and prognosis of patients were performed. Results There were 97(65.1%) male and 52 (34.9%) female in the 149 patients. The onset age of ES was from 30 days to 42 months (median value was 6 months) including 17 patients more than 12 months.The peak age of onset was 4-7 months. One hundred and forty-seven patients manifested clustered spasm. One pair of twins showed single spasm.Other types of seizure were seen before ES onset in 13 (8.7%) patients, and after ES onset in 42 (28.2%) patients.Eighty-three patients (55.7%) were diagnosed as West syndrome (WS). There were 46 patients (30.9%) with cryptogenic cause, 103 patients (69.1%) diagnosed with symptomatic epilepsy, in which 69 patients were with a clear cause. The proportions of developmental delay in the cryptogenic and symptomatic patients were 74.5% and 92.2% after the onset of the ES. The degree of developmental delay was linearly related to the course of ES. The hyperarrhythmia of electroencephalogram (EEG) background was seen in 122 patients (81.9%), and there was no significant difference in hyperarrhythmia between different etiology groups or different onset age groups. The short-term efficiency of topiramate evaluated within one month was 30.5% in 59 newly diagnosed patients. The short-term effective rate of adrenocorticotropic hormone (ACTH) was 80.3% in total 76 patients, but single ACTH treatment was associated with an increased recurrent rate. Conclusion ES is a highly age dependent seizure type that mainly found in WS,which typically follows a EEG hyperarrhythmia and developmental delay. The treatment of ES is difficult. ACTH combined with effective antiepileptic drugs (AEDS) is currently the most reasonable drug treatment program.

Objective To investigate the effects of a proliferation-inducing ligand(APRIL) on migration and invasion of colorectal cancer (CRC) and matrix metalloproteinases (MMPs) expression in order to observe the role of APRIL in CRC metastasis.Methods The siRNA plasmid vector targeting APRIL gene (siRNA-APRIL) was transfected into SW480 cells and recombinant human APRIL(rhAPRIL) was used to stimulate HCT-116 cells.Tumor cell migration and invasion were measured by Transwell chambers.RT-PCR and ELISA were applied to examine the expression level of MMPs.Results Metastatic and invasive capacities of siRNA-APRIL transfected SW480 were significantly inhibited,and these capacities of APRIL stimulated HCT-116 cells were significantly enhanced compared with their respective controls( all P＜0.05 ),accompanied with the alterations of MMPs mRNA and secreted protein expression( P＜0.05).The number of invading cells of SW480 control and rhAPRIL stimulated HCT-116 was significantly decreased by a MMP inhibitor GM6001 ( P＜0.05 ).Conclusion APRIL facilitates migration and invasion of CRC via regulation of MMPs,which suggests that APRIL might be used as a new target for the intervention and treatment of CRC metastasis.

ObjectiveTo determine the effect of multi-criteria decision analysis (MCDA) on the effect of bundle treatment for severe pneumonia.Methods A prospective historical control observation was conducted. Seventy-five patients with severe pneumonia having received MCDA (from January 2013 to August 2014) were assigned as intervention group. MCDA group was set up by the medical staff. Bundled treatment plan was composed of the MCDA evaluation results, anti-infection, phlegm and other conventional treatment measures which was adjust on time until the patient was transferred out of the respiratory intensive care unit (RICU) or died. Seventy patients with severe pneumonia before receiving MCDA (from August 2010 to December 2012) were set as historical control group. Comparison of general condition before treatment and the incidence of hospital infection, average hospitalization cost, duration of RICU stay and mortality between these two groups were performed.Results There were no statistically significant differences in gender, age, past history, and acute physiology and chronic health evaluationⅡ (APACHEⅡ) score at admission between two groups. Compared with control group, the incidence of hospital infection [1.33% (1/75) vs. 11.43% (8/70),χ2 = 4.723,P = 0.030], mean hospitalization cost in RICU (10 thousand Yuan: 3.44±0.79 vs. 3.76±0.91,t = 2.265, P = 0.025), length of RICU stay (days: 15.01±4.22 vs. 16.92±4.79,t = 2.552,P = 0.012) and mortality in RICU [8.0% (6/75) vs. 21.4% (15/70),χ2 = 5.272,P = 0.032] in intervention group was significantly decreased. Conclusions Application of MCDA in the bundle treatment of severe pneumonia could elevate the scientificalness of decision, and reduce the medical cost. Additionally, MCDA is worth to be generalized because the implementation of guidelines can improve the clinical outcome and prognosis of the patients.

Objective　To investigate the diagnosis and treatment of acute rejection of orthotopic liver transplantation (OLT). Methods　From July 1999 to April 2000, two piggyback liver transplantations were performed on two patients with Wilson's disease. Results　Cyclosporine A, azathioprine and methylprednisolone were the baseline immunosuppression management. Acute rejection occured 5 times in the 2 patients. The correct diagnosis was obtained through clinical inspection, liver function test and biopsy. The rejections were controlled by intensive steriod therapy plus OKT3 or FK506. Conclusions　Clinical inspection and liver function test can suggest the episode of acute rejection in time. Hepatic biopsy is the key point for diagnosis of acute rejecton, Reasonable use of immunosppression is critical for the treatment.

3 years. Conclusions Surveillance of circulation system, coagulation system and transplanted splenic function,and correct perioperative treatment are the key points for getting the success of spleen transplantation.
