Actin cytoskeleton in podocyte is a complicated network structure,and the stability of this structure depend on many proteins which located in slit diaphragm,the apical membrane domain and the basal membrane domain with the stimulus of mechanical stress,the actin cytoskeleton can be adaptive regulated to maintain the normal function of glomerulus,and several signal pathways involve in the process,such as RhoA/Rho kinase signal pathway and TRPC6.

Objective To primarily explore the efficacy and adverse effects of the combination of fiudarabine,cytarabine and granulocyte colony-stimulating factor(G-CSF)(FLAG regime)therapy for relapsed and refractory acute leukemia in children.Methods Ten children were treated with the FLAG regime for relapsed and refractory acute myeloid leukemia (AML)and acute lymphoblastic leukemia(ALL)from Feb.2007 to Mar.2010.There were 8 male and 2 female,with mean age 8 years(ranging from 4 to 12 years).AML was diagnosed in 8 children,AML-M2 in 5 cases,AML-M4 in 3 cases.ALL was diagnosed in 2 children,both were B-ALL.Six children had refractory disease,and 4 cases were in relapse.FLAG regime included:fludarabine 25 mg?m-2?d-1,days 1-5;cytarabine 2 g?m-2?d-1,days 1-5;G-CSF 150-300 ?g?d-1,from day 0 to neutrophils ≥0.5?109 L-1.Results Complete remission was obtained in 6 children(60%),partial remission was obtained in 1 child(10%),and 3 children were considered non-response(30%).The total effective rate was 70%.For 8 children with AML,6 children had achieved complete remission(75%),2 children had non-response(25%).While in children with ALL,1 child got partial remission,and the other one had non-response.Myelosuppression and infections due to neutropenia were the most frequent adverse effects,severe nonhematologic toxicity were not observed in these children.And there were no chemotherapy-related death.Conclusions The FLAG regime is effective in treatment of children with relapsed and refractory acute leukemia,especially for the children with the relapsed and refractory AML.The adverse effects from this regime were well tolerated.FLAG regime can give children with relapsed and refractory acute leukemia another chance.

Objective To compare the diagnostic value of prenatal ultrasound with magnetic resonance imaging(MRI)in the abnormalities of fetal urinary reproductive system,and explore the value of combining prenatal ultrasound and MRI in diagnosis of fetal urinary and reproductive system abnormalities.MethodsTwenty-seven fetal abnormalities in urinary reproductive system detected by prenatal ultrasound received MRI examination within 24 hours after ultrasound,confirmed by autopsy or clinical follow-up.The results of prenatal ultrasound and MRI were analyzed retrospectively.Results Ultrasound,MRI,autopsy or after birth,postpartum follow-up confirmed 27 cases of Genitourinary system anomalies,including 2 cases of hydronephrosis,renal agenesis in 6 cases,14 cases of renal cystic disease,renal fusion in 3 cases,1 case of renal tumors,ovarian cyst in one case of crown .Fetal ultrasound can diagnose the majority of the genitourinary system anomalies (25/27),MRI can diagnose fetal anomalies of 26 cases of genitourinary system.Conclusion Ultrasound could diagnose the majority of fetal abnormalities in urology reproductive system accurately.However,combining ultrasound and MRI could establish more precise estimation in urology reproductive system,such as the level of obstruction of urinary system in hydronephrosis,the pulmonary hypoplasia secondary to urology system abnormalities,and location of cyst in the renal parenchyma or in the renal capsule.

Objective To evaluate the effects of an intervention programme of health education and life style modification on postmenopausal osteoporosis women. Methods A total of 120 postmenopausal osteoporosis women were enrolled in this one-year randomized controlled follow-up study and assigned to the intervention group ( Group A, n = 60) or the control group ( Group B, n = 60). Both groups were treated with alendronate sodium. In Group A, education program was performed once a season in the form of face-to-face consultation or group session. In Group B, no additional intervention was used. The primary outcome was patients' compliance in follow-up. The secondary outcomes were change in bone mineral density (BMD).BMD was measured by dual-X-ray absorptiometry (DXA) on lumbar spine and hip at baseline and 12 months after the intervention. Results After one-year intervention,51 subjects in Group A and 38 in Group B completed the follow-up. Groups A showed better compliance. BMD on lumbar spine and hip was significantly increased in both groups when compared with baseline. The changes of BMD on lumbar (0.042+0.067 vs 0.026±0.070,P=0. O29) or Words region (0.029 +0. 129 vs 0.023±0. 143,P=0. 041 ) showed statistical significance between the two groups. Conclusion For alendronate sodium treatment, health management ensures the effectiveness of the therapy and improves the compliance of the patients.

Hypoxiaisoneofthemostimportantfactorsinfluencingcancertherapyandclinicalprogno-sis.With positron emission tomography (PET)widely adopted in clinical practice,the development and appli-cation of PET hypoxia imaging agents has been much popular in the field currently.PET hypoxia imaging can detect tumor hypoxia region noninvasively,which has important significance for optimizing cancer treatment decisions and improving the prognosis of cancer.

Objective To analyze the controlled risk factors of osteoporotic vertebral fractures, and determine the clinical value for the management of risk factors. Methods 626 cases of postmenopausal women were selected, age, height, weight and bone mineral density(BMD) of patients were collected.The Tetrax balance test system was used to assess the fall risks.Vertebral changes of patients were evaluated through X ray of thoracolumbar lateral. The clinical data were analyzed and compared between vertebral fracture group and non-vertebral fracture group. Spearman test was used to analyze the correlation between vertebral fracture and age, height, weight, body mass index(BMI), the risk of fall, body fat and BMD. Results 328 patients presented with osteoporotic vertebral fractures, while the other 298 cases did not suffer from osteoporotic vertebral fractures. There were 426 vertebral bodies involved. Comparing to non-vertebral fracture group, the vertebral fracture group showed higher age [(68.67±9.29)years vs.(63.04± 9.30)years], lower height[(151.10 ± 4.39)cm vs.(154.90 ± 5.86)cm], lower bone mineral density[lumbar spine BMD (0.85 ± 0.16)g/cm2 vs.(0.93 ± 0.17)g/cm2, hip spine BMD (0.72 ± 0.18)g/cm2 vs.(0.81 ± 0.13)g/cm2],higher body fat [(41.30 ± 5.20)％vs.(36.30 ± 5.90)％] and higher fall risk (41.38 ± 25.79 vs. 36.20 ± 26.22) ( P<0.001). While there were no statistical differences in weight and BMI between the two groups, age, height, BMI, body fat, fall risk, lumbar spine and hip BMD were significantly correlated with vertebral fracture (r=0.358,-0.323, 0.169, 0.186, 0.135,-0.398,-0.364, respectively, all P<0.001). Conclusions Decreased bone mineral density, increased age, abdomen fat content and increased fall risk, are the risk factors of osteoporotic vertebral fractures.

Objective To explore the effect of preventing adhesion after the orbital blowout fracture on orbit tissue by amniotic membrane. Design Experimental study. Participants Twenty-six New Zealand rabbits. Methods Establishing rabbit orbital blowout fracture model, the right orbit of twenty rabbits was repaired by hydroxyapatite (HA) parceled of amniotic membrane, and left orbit was only repaired by HA, the orbits of the other six rabbits weren't repaired. Then we got the tissue around bone after one week and one month, and compared the difference of three groups. Main Outcome Measures Inflammatory response of tissue around bone was ana- lyzed by HE, picric acid Sirius Scarlet dying, TGF-?immunohistoehemical observation. Results One week after operation, HE and im- munohistochemistry showed that the difference was not significant in inflammatory response between experimental group and control group (P=0.351, P=0.413), and difference is significant between blank group and experimental group (P=0.012, P=0.041). One month after operation, HE and immunohistoehemistry showed that the difference was significant in inflammatory response between experimental group and control group(P=0.037, P=0.048), and there is no significant difference between experimental group and blank group(P=0.285, P=0.472). Conclusion It has an important role of anti-inflammatory and anti-adhesion in the chronic stage of inflammatory after orbital blowout fracture repaired by man-made plates of amniotie membrane.
