There are four type of Potter typing of cystic kidney disease in children:autosomal recessive polycystic kidney disease,multicystic dysplastic kidney,autosomal dominant polycystic kidney disease and obstructive cystic dysplastic kidney.However,simple cyst of kidney multilocular cystic renal tumors and other genetic syndrome also can make kidney cystic change.Due to the different pathogenesis and pathological basisn,the clinical diagnosis and treatment is also different.The correct diagnosis of these diseases requires chinical classification and determination of the causes of the diseases.This paper will make a review on the common cystic kidney disease in children.

Objective To explore transthyretin (TTR) effect on retinal vascular endothelial cells (hREC) under high glucose and hypoxia environment.Methods hREC and human retinal pigment epithelial cell (hRPEC) were cultured at low-glucose (LG),high glucose (HG) and hypoxia.The glucose concentration was increased from 5.5 mmol/L up to 25 mmol/L,and hypoxia was induced by 200 μmol/L CoCl2.The cells were divided into LG group,LG-hypoxia group,HG group,HG-hypoxia group according to the different cell culture environment.The growth index was detected at 0,4,8,16,24,36,48,60,72 hours after cultured.Furthermore,hREC and hRPEC were also cultured with additional TTR (4 μmol/L),respectively.Then transwell co-culture system was employed to reveal the effects of hRPEC on the growth of hREC.Results At 72 hours after cultured,the growth index of hREC and hRPEC in LG group were increased as compared with LG-hypoxia group and HG group (hREC:F=17.098,22.970;P＜0.05.hRPEC:F=45.442,9.011;P＜0.05);the growth index of hREC and hRPEC were decreased in HG group and HG-hypoxia group (hREC:F=146.184,P＜0.05;hRPEC:F=27.907,P＜0.05).Additionally,hREC could be significantly repressed by added TTR during culture with high concentration of glucose (F=161.430,24.106;P＜0.05).hREC could be significantly increased by added TTR during culture with low concentration of glucose (F =200.486,48.662;P ＜ 0.05).In co-culture process,hRPEC revealed inhibition activity against hREC under both natural and abnormal environment (LG group:F=15.711,P＜ 0.05;LG-hypoxia group:F =45.659,P＜0.05;HG group:F =7.857,P ＜0.05;HG-hypoxia group:F=6.348,P＜0.05).Conclusion Under high glucose and hypoxia environment,the growth of hREC from neovascular could be inhibited by TTR.

Schizophrenia is a common but complex mental disorder affected by multiple factors. Forensic psychiatric assessment of schizophrenia involves evaluations on many aspects, but there is no effective biological identification index for schizophrenia. Researches indicate that dysfunction of dopaminergic neurotransmission plays an important role in the pathogenesis of schizophrenia. Our study reviews the classification, genetic structure of dopamine receptors and the recent pertinent studies between the dopamine receptors and schizophrenia and its forensic significance.

Using observation of the gross and histological changes of skin, intestine, liver and spleen, the spleen index, the popliteal lymph node weight gaining, and the ~(125)I-UdRincorporation assay, the effects of GvHR in the pathogenesis of immunologically mediatedaplastic anemia in mice were studied. Rtsults showed that there were no gross and histological changes due to GvHR foundin skin, intestine, liver and spleen, and the spleen index decreased markedly, and therewere positive popliteal lymph node weight gaining and positive ~(125)I-UdR incorporationassay which showed a dose dependent corrlation. These results suggested that, transfusion of DBA/2 lymphocytes into lethally irradia-ted BALB/c mice could evoke GvHR, but on the other hand, the effects of GvHR werenot very important in the pathogenesis of immunologically mediated aplastic anemia inmice.
