To explore the nyopic shift after cataract extrac tion(ECCE ) with intraocular lens implantation (IOL． ) during childhood．2l children (24 eyes) with ECCE+0L are retrospectively analyzed,and were divided into two groups according to the age． The initial and last postoperative refractive errors were compared． The mean myopic shift was -0.89±0.40 (3～5 years group ) and -0.97± 0.l8 (6～ l0 years N) The difference between two groups was not significantly different(t=0.2l, P>0.05 ) ．The myopic shift was less than l.5re in 91.6W of the w． 83.32 of the eyes achieved a visual acuity of 0.5 or better in their pseudosphakic eyes． Undercorrecting most children 3 to 10 years of ag e by 1.00D from the IOL power predicted to achieve emmtropia．

Objective To investigate multiparametric immunophenotypic features in patients with acute myelocytic leukemia(AML)-M_2 bearing AML-1/ETO gene rearrangements and its predicting value.Methods A multiparametric flow cytometry was used in the study of phenotypic characterization of the subtype of AML.Immunophenotype of 30 patients with AML(M_2/ETO~+)was analyzed by fluorescence in situ hybridization(FISH).The results were compared with 36 patients of AML-M_2 with AML-1/ETO~- (M_2/ETO~-)and 34 acute promyelocytic leukemia(APL)patients.Results There were a population. 15.89%-68.53% the blast cell and a population of more differentiated and heterogeneous myeloid cells in the marrow of 30 patients with M_2/ETO~+.The blast cells had a myeloid phenotype(CD_(33),CD_(13)and MPO) and showed a characteristic pattern of antigen expression.The fluorescent intensity of CD_(33)in patients with M_2/ETO~+ was less than in patients with M_2/ETO~-and APL [ mean fluorescent intensity(MFI):98?75 v. 244?184 and 845?523,both P

it was 4% (3/75). GP73-positive rate in HCC was higher than that of the normal liver tissues (χ2=73.60, P<0.05). sCLU-positive rate in HCC was also higher than that of the normal liver tissues (χ2=207.94, P<0.05). GP73 expression was positively correlated with sCLU expression in HCC (r=0.405, P<0.05). GP73 and sCLU were associated with clinicopathological features including tumor differentiation, TNM stage and vascular invasion (P<0.05); GP73 and sCLU had no correlation with the patient’s gender, age, HBsAg, cirrhosis, AFP value, portal vein thrombosis and tumor numbers (P>0.05). GP73 was associated with survival but not sCLU. Conclusion:GP73 and sCLU have higher positive rates in HCC and GP73 is positively correlated with sCLU. The expression of GP73 and sCLU are probably closely related with the invasion of HCC, which can help evaluate the prognosis of the patients.

Objective To investigate the reasons of blood pressure not reached standard in community outpatients with hypertension.Methods During January 2001 to December 2006,2798 patients fitting the China hypertension guide standard providing prevention and curing were involved in this study.From them,1574 cases were treated repeatedly,and the blood pressure did not continuously reach the controlled standard.The reasons were analyzed by regular visiting and correspondence with patients.Results The reasons of blood pressure not reached controlled standard related with chiefly the following factors:patient had bad compliance,and not positively intervened the way of life,and not took medicine according to the doctor's advice;doctors were not familiar with the methods of preventing hypertension and the treatment was nonstandrad.Conclusion The reasons of blood pressure not reaching standard in community outpatients with hypertension mainly are that the patients have poor knowledge about hypertension and compliance,and the treatment is nonstandrad.

【Objective】 To understand the antigen profile and antibody frequency of Wr^a in voluntary blood donors in Shaanxi province. 【Methods】 Wr^a antigen and antibody screening as well as blood group typing and antibody identification were performed by serological tests and confirmed by genetic testing. 【Results】 The incidence of Wr^a antigen in 7 490 voluntary blood donors was 0.013%(1/7 490), and the frequency of anti-Wr^a in 729 voluntary blood donors was 0.823%(6/729). 【Conclusion】 This study explored the polymorphism of Wr^a antigen and antibodies in blood donors, which is informative in the risk assessment of blood transfusion and the screening and identification of respective antibodies.

Objective To evaluate images quality and diagnostic feasibility of low-dose CT in patients with traumatic rib fractures.Methods Twenty-five patients presented with thoracic iniury were underwent 64-slice spiral CT scanning in inspiration breath-hold technique.Two scan protocols were performed.In one scan protocol noise index(NI)is 11,and in another NI is 21,but the other scan parameters were no difference.The mean value of tube current,the volume CT dose index(CTDIvol),and effective dose(ED)were recorded.Image quality was scored by 2 experienced radiologists using the 5-points scale.The numbers and degrees of rib fractures were recorded.The data were tested by using the Wilcoxon signed rank sum test.The differences of the inter-observer were determined by Kappa statistics.Results The mean CTDIvol and ED in scan protocol with NI of 11 were(13.88±5.17)mGy and(8.14±3.21)mSv,and that with NI of 21 were(3.91±1.57)mGy and(2.31±0.97)mSv.Compared the scan with NI of 11.there was 72%intrinsie dose reduction in the scan with NI of 21.The mean value of tube current in scan with NI of 11 and 21 were(195.88±69.33)mAs and(54.56±21.54)mAs.AIl patients with 11 and Ⅲ degree and most patients with I degree rib fractures that identified by the scan with NT of 11 were detected by the scan with NI of 21.There were no statistical difference between two scaus with the Wilcoxon signed rank sum test.The diagnostic acceptability and image noise score in the scan with NI of 11 were 4.9±0.2 and 4.6±0.5.and that with NI=21 were 3.5±0.5 and 3.3±0.5.There was prefect concordante in the inter-observers in diagnostic acceptability on finding of rib fractures.diagnostic acceptability and image noise(Kappa=0.876,0.820,0.792,P<0.01)between two scan protocols.Conclusion Rib fractures can be diagnosed by the low-dose CT using the scan protocol with NI of 21.
