This article reviews the immunopathogenesis of cystic echinococcosis in the following seven aspects: innate immunity,establishment phase immunity,cystic phase immunity,influencing factor of CD4+ T cell polarization,cytokine function in infected host,Echinococcus granulosus infection and allergy,and immune evasion mechanism.

The diagnostic core of multiple sclerosis(MS) always requires dissemination in space and time since the publication of the first criteria over 40 years ago.Though several modified clinical criterias have been proposed to diagnosis MS,no paitents must meet such condition in diagnostic criteria because of the reticular clinical manifestation of this disease.The diagnosis of MS is still based on clinical parameters including detailed history and a careful examination to exclude alternative disease.The effects of some disease modifying agents to MS have been confirmed by evidence-based medicine.But the intact treatment plan must contain aspects of acute attacks,prevention of relapses and progression,management of symptoms,and rehabilitation.The individualized treatment is needed according to the medical insurance,payment ability and other influencing factors in China.

Objective To explore the clinical effect of chlorpromazine(TMZ)in treatment of chronic heart failure(CHF).Methods 70 patients with CHF were randomly divided into control group and treatment group 35 cases in each gronp,control group was given conventional treatment,treatment group on the basis of additional application TMZ,20mg/times,3 times/d.8 weeks after the observation and comparison of two groups of cardiac function in improving the situation.Results Treatment group before the treatment of LVEF(38.0 ± 2.4)％ After treatment,LVEF(48.0 ±2.3)％ ;control group before treatment LVEF(38.2 ±2.2)％ after treatment,LVEF(42.0 t2.5)％ ;Twosets of treatment LVEFdifference statistically significant(t =6.9419,2.8482,allP ＜ 0.05); Treatment group compared with control groups after treatment improve even more obvious(t =4.3147,P ＜0.05)o Control groups and then hospitalized 10 cases(28.5％),the treatment group hospitalization 3 cases(8.5％),both groups rate difference statistically significant(x2 =4.629,P ＜0.05).Both groups were no deaths,no serious adverse effects.Conclusion General against heart failure therapy on the basis of the combined with TMZ could significantly improve the cardiac function of patients with chronic heart failure,reducing hospitalization rates.

Objective To observe the effect of several residual adhesive methods on the enamel surface ,and conduct lab evalua-tion .Methods Sixty premolars extracted because of orthodontic treatment .And all the teeth were randomly divided into 3 groups . Group 1:tungsten carbide burs + silicon particles ;Group 2 :ultrasonic scaling + silicon particles ;Group 3:silicon particles ,each with 20 premolars .After underwent several methods ,the surface roughness differences ,operation time were determined and ob-served with the scanning electron microscope .And the result was statistically analyzed .Results There were significant differences in the surface roughness and operation time among the three groups (P<0 .05) ,The scanning electron microscope after polishing showed that the teeth surface had different degrees of injury ,the silica particles group had less superficial scratch .Conclusion The tungsten carbide burs and ultrasonic instrument for debonding before the silica particles had less superficial scratch .

Objective:To investigate apoptosis of spleen cells in infected mice by immunization with recombinant BCG-Eg95 vaccine of Echinococcus granulosus(Eg) and against challenge with Eg protoscoleces.Methods:BALB/c mice were vaccinated with the vaccine subcutaneously,intranasally,orally and intramuscularly respectively.The mice were then challenged with Eg protoscolexes at 8w of vaccination and sacrificed in 18w of infection to get spleen.Spleen cells were separated to measure apoptotic rate by FACsort with BCG and PBS served as control.Results:Apoptotic rate in the immunization group was lower than that in the control.Apoptotic rates in the oral or intramuscular group were significantly lower than that in the subcutaneous or intranasal group.Conclusion:Apoptosis of spleen cells in mice may be induced by infection with hydatid cyst,but is inhibited by immunization with rBCG-Eg95 vaccine.Oral or intramuscular vaccination may be the good regimen.

Objective To construct and identify of a plasmid mediated high efficiency of RNA interference(RNAi) against Nogo-66 receptor(NgR).Methods After cloning of NgR by RT-PCR,the fragments were inserted into pcDNA3.1/CT-GFP-TOPO to produce plasmid expressing NgR-GFP fusion protein.Four pairs of oligonucleotide were designed according to NgR sequence and annealed.The resulting fragments were ligated into short hairpin RNA(shRNA) expressing plasmid.The plasmids expressing NgR-GFP fusion protein and shRNA were co-transfected into AAV-293 cells.RNAi efficiency against NgR was observed under fluorescent microscope and calculated by Western blotting.Results The interference efficiency of one sequence was above 90%.Conclusion A plasmid mediated high RNAi efficiency against NgR is constructed successfully.

By designing the circuit structure of preamplifier and selecting new elements such as ultra low noise operational amplifier and linear opto-coupler,some difficulties in EEG acquisition is overcome and the Common Mode Rejection Ratio(CMRR) of preamplifier is highly increased.So EEG can be amplified and detected well.

Objective To investigate the reduction of hydatid cyst weight and change of splenocyte lymphokines in mice immunized with recombinant BCG-Eg95 vaccine of Echinococcus granulosus(Eg). Methods BALB/C mice were subcutaneously, intranasally, orally and intramuscularly vaccinated respectively, with BCG and PBS served as controls. The mice were challenged with Eg protoscolices 8 weeks after vaccination and sacrificed in 18 weeks after infection. The weight of hydatid cyst was measured and reduction of the weight was obtained, spleens were used to separate splenocytes which were cultured under stimulation with EgAg or ConA. The supernatant was collected to measure the level of IL-2、IFN-?、TNF- and IL-4 by ELISA. Results The hydatid cyst weight reduced by 45.77%, 18.20%, 88.05% and 92.46% respectively in the 4 immunization groups. In comparison with PBS control, the level of IL-2、IFN-?and TNF-?was (30.0?0) pg/ml, (65.0?0) pg/ml and (425.0?10.7) pg/ml respectively in the intramuscular group with a significant increase, but that of IL-4 decreased, with a value of (10.0?0) pg/ml. Conclusion The recombinant BCG-Eg95 vaccination induces Th1 response in mice against challenge infection.
