On the clinic,the main treatment of autoimmune diseases were used immunosuppressant,but large-scale use of immunosuppressive agents could cause of the delayed dysfunction,side effects such as infection,tumors and so on,so-induced immune suppression and immune tolerance response was the most effective way.So far,dendritic cells(DC) was the most powerful professional antigen-presenting cells.On one hand,DC as a full-time antigen-presenting cells and trigger regulation of the inherent and acquired immune response,start the immune response;On the other hand,DC through a variety of mechanisms induced antigen-specific T cells incompetent,show strong plasticity in immune tolerance and play an important role in immune regulation.Nuclear factor(NF)-?B is a nuclear transcription factor.In the immune response,NF-?B in the dendritic cells regulation of their own including development,maturity,the antigen-presenting,to stimulate T cells functions and so on.Such adjustments play an important role in the incidence of autommine diseases,could became a new target treatment of autommine diseases.

Vertigo is a kind of patients' subjective feelings. The severity of vertigo is closely related to many factors. But we are short of a well accepted quantitative evaluation method capable of accurately and comprehensively evaluating vertigo in clinics. Reducing the onset of vertigo, enhancing the re- covery of equilibrium function, and improving the quality of life of vertigo patients should be taken as the focus of evaluating therapeutic effects. As for establishing a Chinese medical effectiveness evaluation system for vertigo, we believe we should distinguish different "diseases". We could roughly identify it as systemic vertigo and non-systemic vertigo. For systemic vertigo, the efficacy of vertigo could be comprehensively evaluated by UCLA vertigo questionnaire or dizziness handicap inventory combined with equilibrium function testing indices. But for non-systemic vertigo, the efficacy of vertigo could be comprehensively evaluated by taking UCLA vertigo questionnaire or dizziness handicap inventory as main efficacy indices. Secondly, we should analyze different reasons for vertigo, choose symptoms and signs in line with vertigo features as well as with Chinese medical theories, and formulate corresponding syndrome effectiveness standards according to different diseases. We should not simply take syndrome diagnosis standards as efficacy evaluation standards.

OBJECTIVE: To analyze the medical records of poisoned children to provide references for the forensic identification of melamine-tainted milk powder poisoning. METHODS: Medical records of six fatal cases of consuming some brand melamine-tainted milk powder were studied, specifically the poisoning symptoms, medical imaging, blood biochemical tests, treatment and prognosis. RESULTS: The major medical problems of these eight-month sick infants were urinary tract obstruction caused by urinary tract calculi. The poisoned infants developed oliguria, anuria and other symptoms, eventually, acute renal failure or other complications leaded to death. The serum BUN and Cr abnormally increased. CONCLUSION By considering the toxicological effects of melamine, it was concluded that the deaths of these sick infants were related to the melamine poisoning.

Objective To investigate the value of acoustic radiation force impulse (ARFI) on evaluating the renal tubular atrophy and interstitial fibrosis of IgA nephropathy(IgAN).Methods 117 patients diagnosed with IgAN,and 80 normal cases were examined with conventional ultrasonography and ARFI,recording the shear wave velocities(SWV),the hemodynamics and the renal biopsy results to quantify the elastic changes of renal cortex,with the aim of assessing AFRI's advantages on early diagnosing the impair of kidney.Results The SWV value of renal cortex,renal medulla of IgAN group were smaller than that of normal group (P ＜0.05),while the collective system SWV value had no difference(P ＞0.05).According to the ROC curve,the cut-off value of SWV in renal cortex was 2.7 cm/s.The accuracy of the diagnosis was 71 ％,which was better than RI (61.9％).The SWV value of the renal cortex decreased with the different stage of 1,2,3,4,but stage 5 was larger than stage 4.The degree of renal tubular atrophy and interstitial fibrosis(T) can be classified by the SWV of renal cortex,and the SWV of T2 was larger than T1 (P ＜0.05).Conclusions By quantifying the elastic change of kidney,ARFI technology is able to distinguish the degree of renal tubular atrophy and interstitial fibrosis,diagnose renal impairment early and judge the clinical stages.Furthermore the sensitivity,specificity,accuracy of it are superior to hemodynamic.

Objective To study the effect of intracoronary stenting for bifurcational lesions on the related side branches. Methods One hundren and twenty patients with 132 coronary bifurcational lesions were enrolled in the study. Intracornary stents were deployed in the lesions. The incidence of side branch oppression was analysed. Results Twenty-four side branches were oppressed during PCI (14.28%), especially in type Ⅰ and type Ⅳ bifurcation lesions. Conclusion The details of PCI and morphotogical characteristics of bifurcation lesions were the important factors leading the side branch oppression during PCI in bifurcation lesions.

Objective To evaluate the clinical outcome of patients who suffered from acute myocardial infarction with angiographically normal coronary arteries (MINC) Methods Forty patients (mean age: 52 6?12 2 years; range: 30-75 years) admitted with acute myocardial infarction had normal coronary arteries after AMI, defined by normal or insignificant 50% diameter stenosis) The risk factors, clinical data, ventricular functions and the long term outcomes were compared between Group A and Group B Results Hypertension and previous angina were more frequent in Group B Patients in Group A had a lower number of risk factors associated with them than patients in Group B LVEF during hospital was higher in Group A than in Group B The mean follow up period was 67?40 months in Group A and 68?34 months in Group B Incidencs of rehospitalization, repeat intervention therapies, heart failures, and total heart events were fewer in Group A than in Group B Conclusion These data suggest a favorable long term prognosis and fewer risk factors in patients who suffered from acute myocardial infarction with normal or nearly normal coronary arteriogram

Objective To study the angiographic anatomic characteristics of renal arteries in Chinese.Methods Selective renal angiography was performed immediately after coronary artery angiography in(1?057) Chinese patients,including 702 males and 355 females.The mean age of them were 59.3?8.3 years.Six French JR4 catheters were used via transfemoral approach.Three to five milliliters nonionic contrast media were injected manually into each renal artery and cine pictures were taken at an anterior-posterior view.Results A single-renal-artery was found in most of the patients(87.23% at the left side and 89.97% at the right side).In the others,two or even more independent renal arteries were found at one or both sides.Most of the renal arteries (87.79% at the left side and 91.20% at the right side) originated between the upper third of the first lumbar vertebra and the upper third of the second lumbar vertebra.The right renal artery ostium was located superior to the left one in 45.13% of the cases.In the other 45.41% of them,renal artery ostia of both sides were at a same level.Conclusion Anatomic variations in the number and origin of renal arteries are not nare in Chinese.Understanding the angiographic anatomic characteristics of renal artery would be useful for renal artery interventions.

Objective To evaluate the safety and immunogenicity of group A/C meningococcal polysaccharide conjugate vaccine.Methods The double-blind,randomized,parellel controlled,single central clinical trial was carried out to evaluat safety and immunogenicity of MCV-A/C.Results 4-fold rise rate of antibody to group A,C and A/C were more than 90 percent after MCV.The GMTs of antibody serogroup A and C were more than 1:150 in four trial groups aged 3-5 months,6-23 months,2-15 years and 16-30 years,for which the susceptive subjects seroprotected.There were no significant differences between MCV and the control group in the systemic and local reactions rates.The systemic and local reactions rates after the first,second and third dose of MCV were low.And no severe systemic and local reactions.Conclusion Group A/C MCV was safe and immunogenic for the population≥ 3 months old.Registration National Food drugs Surveillance administrative bureau,Medicine Clinical Experiment Written Directive from a superior" number:2006L04776.
