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 explore the related factors for the prognosis in elderly cancer patients with cerebral metastases,to study the adaptability of brain metastasis in recursive partitioning analysis (RPA)and the prognosis Assessment (GPA) Scale,in order to provide the basis for the prognosis assessment and treatment in the elderly patients with brain metastasis.Methods A retrospective analysis was studied in 102 elderly cancer patients with brain metastasis (aged 60 years and over) with complete follow-up data in our hospital from January 2005 to January 2012.Survival analysis was performed by using the Kaplan-Meier method.Univariate analysis of ethnicity,age,Karnofsky score,gender,smoking,primary tumor origin,the number of intracranial metastatic tumor,intracranial and extracranial metastasis,the efficacy of treatment for primary tumor,the treatment of brain metastases were analyzed by Log-rank test.Results The median survival time was 6 months.The 6-month and 12-month survival rates were 54.90％ and 16.67％ respectively.Univariate analysis showed that Karnofsky score,smoking,the number of intracranial metastatic tumor,time to diagnosis and treatment,the efficacy of treatment for primary tumor and other underlying diseases were the relative factors for prognosis of elderly cancer patients with brain metastases (x2 =20.828,5.737,7.395,5.379,11.556,6.844,all P＜0.05).Cox multivariate regression analysis showed that the Karnofsky score,the number of intracranial metastatic tumor,the efficacy of treatment for primary tumor and other underlying diseases were the independent prognostic factors (all P＜0.05).The median survival periods in RPA class Ⅰ,Ⅱ,Ⅲ were 11,7,4 month respectively (x2 =27.358,P＜0.001).The median survival periods in GPA class Ⅰ,Ⅱ,Ⅲ-Ⅳ were 5,8,13 months respectively (x2 =29.570,P＜0.001).Conclusions Karnofsky score,the number of intracranial metastatic tumor,the efficacy of treatment for primary tumor and other underlying diseases are the independent factors for the prognosis in elderly cancer patients with cerebral metastases.RPA and GPA classification have a good adaptability in elderly patients with brain metastases.

BACKGROUND:Intertrochanteric fracture can obtain good curative effects after active effective internal fixation in early stage.
OBJECTIVE:To compare dynamic hip screw+trochanter stabilizing plate and Gamma nail fixation for treatment of Evans type IIIB and type IV intertrochanteric fracture.
METHODS:A total of 67 patients with Evans type IIIB and type IV intertrochanteric fracture, including 28 cases undergoing dynamic hip screw+trochanter stabilizing plate and 39 cases undergoing Gamma nail, were selected from Chongming Branch, Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from February 2009 to November 2012. Al patients received antibiotics and functional exercises after treatment. Time of therapy, intraoperative bleeding amount, fracture healing time and Harris Hip Score were retrospectively analyzed in patients of both groups.
RESULTS AND CONCLUSION:Al patients were fol owed up for 6-45 months, averagely 21 months. (1) One patient affected infection in the dynamic hip screw+trochanter stabilizing plate group. He was healed after fixation removal half a year after drug exchange. One obese patient experienced injury again during out-of-bed activity at 3 weeks after treatment in the Gamma nail group. Fracture appeared at distal end of lock pin, and healed after replaced by Gamma nail. Trochanteric stabilizing plate was unstable in four patients of the Gamma nail group. They affected severe pneumonia after over 6 weeks of lying in bed, and healed after treatment in the medical department (2) Coxa vara appeared in two cases of the dynamic hip screw+trochanter stabilizing plate group, and three cases in the Gamma nail group. Fracture healing was achieved in al patients. (3) The time of therapy was longer, and intraoperative bleeding amount was significantly more in the dynamic hip screw+trochanter stabilizing plate group compared with the Gamma nail group (P<0.05). No significant difference in healing time and Harris Hip Score was detected between the two groups (P>0.05). Dynamic hip screw+trochanter stabilizing plate and Gamma nail are effective methods for treatment of Evans type IIIB and type IV intertrochanteric fracture. To choose a suitable fixator, we should aggregately analyze fracture stability, healing state and the degree of osteoporosis.
