ObjectiveTo investigate the role of vascular endotheliar growth factor(VEGF),chemokine receptor 4(CXCR4) and stromal cell-derived factor-1(SDF-1) in Wilms tumor as well as their relationship with clinical features by examining the expressions of VEGF,CXCR4 and SDF-1.MethodsThirty cases of Wilms tumor samples and 12 cases of adjacent kidney tissue were collected from the First and the Third Affiliated Hospital of Zhengzhou University from May 2003 to May 2008.Thirteen boys and 17 girls aging from 4 months to 7 years old of whom were 22 favorable histologic types and 8 unfavorable histologic types.By means of cytoplasm to dye buffy for masculine cell,staining intensity and percentage of positive tumor cells serve as the judgment criteria for being positive or negative.All tissues would be tested by hematoxylin and eosin stain at the same time.ResultsThe positive expression rate of VEGF,CXCR4 and SDF-1 in Wilms tumor were 63.33%,70.0% and 53.33%.Those in adjacent normal kidney tissue were 25.0%,8.3% and 16.7%.The 2 groups were statistically significant(Pa

Objective To investigate the clinical features of spinal muscular atrophy type Ⅱ.Methods The data of clinical manifestation,laboratory data, onset, diagnosis, and rehabilitation of 53 outpatients suffering from spinal muscular atrophy type Ⅱ (SMA-Ⅱ) were analyzed. Results Among 53 patients with SMA-Ⅱ confirmed by molecular genetic tests, 27 patients were male while 26 were female. The mean age was 3.35 years (ranged 0.75~7.8 years), and the age receiving gene diagnosis was 17.27 months. Only 15% had a family history,and abnormalities were found in 23% patients' mothers during pregnancy. 83.4% of them had water choke cough, while 87% expectoration weakness. None of them had cough assist machines and had regular spirometry monitoring. 53% of the patients took semi-liquid diet, however,none of them used stomach tube. Symmetrical flaccid paralysis was so remarkable, even muscle strength of lower limbs in 87.7% of these patients were only grades 1-2. 92% had scoliosis, while 83% had tendon contracture. EMG showed extensive neurogenic changes. All children did not accept normal pre-school education, and 85% patients did not accept formal rehabilitation. Conclusion Most of phenotype of SMA-Ⅱ for the children was similar and more severe in China. Most of the patient didn't get formal education, rehabilitation and care.

AIM:To observe the effects of Dickkopf-3 ( Dkk-3 ) in diabetic retinopathy ( DR ) circulating blood in patients with the expression level, the Dkk - 3 development changes in the diabetic retinopathy of significance in the diagnosis of early DR.
● METHODS: Eighty - five type 2 diabetic patients, included the non - proliferative diabetic retinopathy ( NPDR ) 23 patients, proliferative diabetic retinopathy, proliferative DR ( PDR ) in patients with 30 and non-diabetic retinopathy ( NDR ) with 32 cases. The same period of healthy physical examination was selected as control group ( 80 cases ) . Serum samples were collected, and the relative expression level of Dkk-3 was detected by enzyme - linked immunosorbent assay ( ELlSA) double antibody sandwich assay. The statistical differences were compared between groups.
●RESULTS: The plasma level of Dkk - 3 ( 430. 16 ± 198. 11pg/mL) in DR patients was significantly lower than that in healthy control group (627. 48±294. 45 pg/mL; P<0. 05 ) and NDR patients ( 601. 99 ± 194. 16 pg/mL; P<0. 05). While there was no significant difference in Dkk-3 level between NDR and healthy control group ( P =0. 729). The level of PDR in patients with Dkk-3 (396. 38± 185. 59 pg/mL) was lower than that of NPDR (538. 82 ± 187. 20 pg/mL;P=0. 002).
●CONCLUSION:The decrease of Dkk-3 level may be related to the occurrence and development of diabetic retinopathy, and there is a significant correlation with PDR. Circulating blood Dkk - 3 protein in diabetic retinopathy has a certain differential efficacy, it is likely to become diabetic retinopathy patients peripheral blood test indicators.
