Objective To investigate the etiology and prognostic factors of acute kidney injury (AKI) in pediatric patients . Methods The clinical data of children patients with AKI in this hospital ,including the clinical features ,causes and outcomes ,were retrospectively analyzed .The relationship between the risk factors and prognosis was analyzed .Results Infants were dominated by the prerenal factors and the other age groups were dominated by the renal factors .The univariate analysis revealed that the AKI stage ,etiology ,mechanical ventilation ,sepsis/septic shock ,MODS ,acidosis ,creatinine initial value ,creatinine peak value and serum potassium were the factors affecting prognosis .The Logistic regression analysis showed that mechanical ventilation ,MODS and sep-sis/septic shock were the independent risk factors affecting prognosis .Conclusion The etiology of AKI in children is diverse and its distribution has the age characteristics .Mechanical ventilation ,MODS and sepsis/septic shock are the independent risk factors af-fecting prognosis .The early diagnosis and the active treatment conduces to improve prognosis .

Standardized residency training is the main form of postgraduate medical education.In this article, we analyzed a delayed diagnosed case with Cushing syndrome.The patient saw the doctors in provincial level hospitals for many times within a year, while specialists missed diagnosis by only concerning the symptoms related to their own specialties, instead of integrating all the manifestations.We believe that standardized residency training provides residents a broader horizon of related specialties, which is irreplaceable by fellowship training program, and is the essential of comprehensive analysis of complex clinical situations.Standardized residency training will also be helpful for diminishment of the educational gap between different medical colleges and improvement the medical level of the whole nation.
4.The dynamic observation on splenocyte cytokines in mice immunized with the transgenic alfalfa containing Eg95-EgA31 fusion gene of Echinococcus granulosus
Chinese Journal of Endemiology 2010;29(1):61-65
Objective To investigate the dynamic changes of splenocyte cytokines in mice immunized with the transgenic alfalfa containing Eg95-EgA31 fusion gene of Echinococcus granulosus (Eg). Methods Eighty-eight Balb/c mice were divided into 2 groups randomly according to body weights,and immunized orally or intranasally with 100μl or 10μl extracted leaf protein from the transgenic alfalfa(20 g/L) respectively once per 3 days for 2 months. Four mice randomized from each group were killed to get splenocyte on week 0(control),2,4,6,8,10,12,14,16,18 and 20 after the last immunization. The splenocyte were cultured in medium for 48 hours with EgAg or concanavalin A (ConA) stimulation to induce the interleukin (IL)-12,interferon γ(IFN-γ) and IL-10,and cultured for 72 hours with EgAg or lipopolysaccharide (LPS) stimulus to induce the tumor necrosis factor α (TNF-α). Then the supernatant was collected to measure the level of IL-12,IFN-γ,TNF-α and IL-10 by ELISA. Results In the oral immunization group,the level of IL-12,IFN-γ,TNF-α and IL-10 increased significantly from week 4 to week 6,week 2 to week 8,week 2 to week 6 and week 4 to week 12,respectively,reaching the highest level(25.0±5.8)ng/L on week 4,(575.0±28.9)ng/L on week 2,(50.0±11.5)ng/L on week 2 and (42.5±2.9)ng/L on week 8,respectively,as compared with the values on week 0[(11.3±2.5),(125.0±28.9),(11.3±2.5),(12.5±2.9)ng/L,all P < 0.01]; in the intranasal immunization group,it was similar about the values of IL-12,IFN-γ,TNF-α and IL-10 could be seen from week 4 to week 6,week 2 to week 10,week 4 to week 10 and week 6 to week 16,respectively,reaching the highest level(25.0±5.8)ng/L on week 6,(725.0±28.9)ng/L on week 4,(27.5±2.9)ng/L on week 6 and (60.0±11.5)ng/L on week 6,respectively,as compared with the values on week 0[(11.3±2.5),(125.0±28.9),(11.3±2.5),(12.5±2.9)ng/L,all P < 0.01]. The cytokine levels in the groups with EgAg,ConA or LPS stimulus were significantly higher than those in the corresponding splenocyte suspension groups(P < 0.05 or < 0.01),and the cytokine levels in the groups with ConA or LPS stimulus were obviously higher than those in the corresponding groups with EgAg stimulation (P < 0.05 or < 0.01). Conclusion The mixed responses of Th1 and Th2 types can be induced in mice immunized with the transgenic alfalfa in the early period post immunization(2-10 weeks).
5.The change of splenocyte subsets in Balb/c mice by immunization with the transgenic alfalfa(Medicago sativa) containing Eg95-EgA31 fusion gene of Echinococcus granulosus
Chinese Journal of Endemiology 2010;29(4):387-390
Objective To investigate the change of splenocyte subsets in Balb/c mice immunized with transgenic alfalfa(Medicago sativa)containing Eg95-EgA31 fusion gene of Echinococcus granulosus(Eg) and challenged with Eg protoscoleces.Methods Leaf protein was extracted from transgenic alfalfa containing Eg95-EgA31 fusion gene by heat-coagulation method,and concentration of 20 g/L was used in the study.Meanwhile,leaf protein extracted from the transgenic alfalfa containing blank vector(pBI121)and the normal alfalfa was served as control.Thirty-two female Balb/c mice were randomly divided into 4 groups,8 mice in each group.Oral group was immunized with the leaf protein containing Eg95-EgA31 fusion antigen intragastrically(100μl per mouse);intranasal group was immunized with the leaf protein containing Eg95-EgA31 fusion antigen intranasally(10 μl per mouse);blank vector group was vaccinated intranasally with 10μl leaf protein with blank vector(pBI121);and normal control group was given 100μl normal leaf protein intragastrically.All mice in the above mentioned groups were immunized every 3 days for 2 months.Then,the mice were challenged intraperitoneally with Eg protoscoleces(50 protoscoleces per mouse)8 weeks after last vaccination and sacrified 24 weeks pest infection to separate the splenocytes.Flow cytometry was used to measure the percentages of CD4+ and CD8+ T ceils subsets.Resuits Compared with the normal control group(0.166±0.018,0.083±0.006,2.019 ±0.369),the percentages of CD4+(0.286±0.009)and CD8+(0.102±0.004)T cell subsets and the ratio of CD4+/CD8+(2.814±0.014)in oral group increased significantly (P<0.01 or<0.05).The percentage of CD4+ subset(0.269±0.016)and the ratio of CD4+/CD8+(2.955±0.986) in intranasal group was significantly higher than that ofthe normal control group(all P<0.01).The percentage of CD4+ subset in oral group was significantly higher than that of the intranasal group(P<0.05).No significant difference was found in the percentages of CD4+ and CD8+ T cell subsets and the ratio of CD4+/CD8+ between the blank vector group(0.169±0.018,0.093±0.019,1.852±0.188)and the normal control group(all P>0.05).Conclusions CD4+ T cell may play an important role in the protection induced by transgenic alfalfa vaccine against the challenge of Eg protoscoleces.Intragastrical immunization may be a good route.

p38 signaling pathway is an important branch of mitogen-activated protein kinase(MAPK)-mediated signal transduction pathway. It plays pivotal roles in various physiological and pathological events, such as inflammation, cell stress, apoptosis, cell cycle and growth. Previous research in osteoarthritis, p38 participation was found in the inflammatory factors activate, cartilage cell apoptosis etc. Disc degeneration, also associated with inflammatory response, apoptosis and pathological changes which p38 MAPK signaling pathways role is not clear. Some reports about this area are reviewed in this article.
