Twenty five patients with obstructive sleep apnea hypopnea syndrome (OSAHS) were classified as mild, moderate and severe grade according to apnea hyponea index and lowest oxyhemoglobin saturation.Lower limbs were examined with ultrasonography, blood routine and D-dimer levels were measured in all patients.The results revealed an increased incidence of deep vein thrombosis with the extent of obstructive sleep apnea.There was no deep vein thrombosis in patients with mild-grade OSAHS, while there were 2 in moderate and 3 in severe patients.The blood D-dimer levels were (498 ± 22) pg/L, (659 ±43 ) μg/L, ( 1528 ± 181 ) μg/L in mild, moderate and severe patients, respectively.The hemoglobin levels were (150 ± 8) g/L, ( 183 ± 15) g/L and (261 ± 26) g/L in mild, moderate and severe patients,respectively.There may be some association of obstructive sleep apnea hypopnea syndrome with deep vein thrombosis.

Objective To explore the value of MRI on fetal autosomal recessive polycystic kidney disease (ARPKD).Methods Sixteen pregnant women,aged from 28 to 38 years (average 30 years) and with gestation age from 22 to 36 weeks (average 25 weeks) underwent MR scanning with a 1.5 T MR unit within 24 to 48 hours after ultrasound examinations.The imaging sequences included steady-state free-precession (SSFP) sequence,single-shot turbo spin echo (SSTSE) sequence and T1-weighted fast imaging sequence.Prenatal US and MR imaging findings were compared with autopsy or pathological results.Results A total of 16 cases of ARPKD showed bilateral markedly enlarged kidneys and diffuse high signal small cysts in renal medulla on SSTSE sequence.Among the 16 cases,11 cases were with oligohydramnios,1 1 cases were with pulmonary hypoplasia,and 6 cases were with hepatic fibrosis.Eleven cases of pulmonary hypoplasia and 6 cases of hepatic fibrosis were all missed by US.For the diagnosis of the renal anomalies,US missed one case.MRI diagnosis was correct in all these cases.Conclusions MRI shows great advantages on the diagnosis of fetal ARPKD,and it is not affected by the amount of amniotic fluid.It can be used to evaluate kidney and lung abnormalities accurately.

Aberrant activation of the phosphatidylinositol 3-kinase(PI3K)-protein kinase B(PKB,Akt)-mammalian target of rapamycin(mTOR) pathway is commonly observed in human cancer and is critical for cell survival, proliferation and differentiation.A variety of small molecule inhibitors targeting PI3K-Akt-mTOR pathway are under clinical studies.This review will summarize the recent studies in terms of the PI3K-Akt-mTOR signaling pathway and cancer,research progress of the antitumor activity possessed by PI3K-Akt-mTOR inhibitors,as well as the recent research in the related field conducted by our group.

Objective To detect the expression of a novo tumor suppressor gene PTEN and DNA direct repair enzyme MGMT in gynecomastia. Methods Immunohistochemical SP method was used to detect expression of PTEN and MGMT protein in 68 cases of gynecomastia(experiment group) and 24 cases of mammary gland of control group. The selected examples were divided into three different age groups and three different histological types. Results The PTEN and MGMT protein were all expressed in nucleusr of ductal cellula epithelialis. The expression level of PTEN and MGMT proteins in gynecomastia was significantly lower than that of mammary gland of control(P

Objective To explore the diagnostic value of MRI on fetal congenital limb deformities.Methods Sixteen pregnant women,aged from 22 to 40 years (average 29 years) and with gestation from 22 to 39 weeks (average 29 weeks) were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound studies. Acquisitions consisted of coronal, sagittal, and axial slices relative to the fetal brain, spine, thorax, abdomen, especially limbs using 2D FIESTA sequences. Prenatal US and MR imaging findings were compared with postnatal diagnoses (4 fetuses) or autopsy (12 pregnant women,13 fetuses). Postnatal evaluation included US, MR imaging, computed tomography, and physical examination. Results Of the sixteen pregnant women (15 with a single fetus and 1 with twin fetuses) ,17 fetuses were found. Those limb deformities of sixteen pregnant women included congenital both upper extremities amelia (1 case), sirenomelia sequence (1 case), micmmelia (5 cases, 1 of which were twins),bilateral clenched hands (2 cases), right pelydactyly (1 case), simple right ectrodactyly (1 case), right dactylolysis(1 case), simple club foot (2 cases), hydrocele spinalis with club foot (2 cases), 1 of the 2 cases with bilateral clinodactyly. In 14 of 16 cases, the diagnoses established by MR imaging were correct when compared with postnatal diagnosis, and prenatal MR diagnosis was inaccurate in 2 cases. Conclusion Prenatal MRI is effective in the assessment of congenital limb deformities of fetuses, it can yield information additional to that obtained with US, and further correct US diagnosis.

Objective To explore the diagnostic value of MRI on fetal neural tube defects.Methods Ten pregnant women,aged from 25 to 35 years(average 28 years)and with gestation from 20-39 weeks(average 33 weeks)were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound(US)studies.The imaging protocol included fast-imaging employing steady-state acquisition,single-shot FSE and T_1-weighted fast inversion recovery motion insensitive sequences in the axial,frontal,and sagittal planes relative to the fetal brain,thorax,abdomen,and spines.Prenatal US and MRI findings were compared with postnatal MRI diagnoses(3 fetuses)or autopsy(7 fetuses).Results Ten pregnant women(9 with a single fetus and 1 with twin fetuses)were examined.For all cases,the diagnoses established by MRI were correct when compared with postnatal diagnosis or autopsy.In 7 cases,US and MRI findings were in complete agreement with postnatal diagnoses.US missed the diagnosis in 1 case and misdiagnosed in 2 cases.Ten neural tube defects in this study included anencephaly(1 case),exencephaly (1 case),meningoencephalocele associated with amniotic band sequence(1 case),meningocele(1 case),thoracic myelomeningocele(1 case),lumbar spinal bifida(1 case),sacroiliac myelomeningocele(2 cases),sacroiliac large cystic spinal meningocele(1 case),sacroiliac spinal bifida(1 case).Conclusions Prenatal MRI is effective in the assessment of fetal neural tube defects.It can exactly discriminate herniated contents and locate the spinal lesion level.

Objective To explore the diagnostic value of MRI on fetal congenital diaphragmatic hernia(CDH).Methods Fourteen pregnant women with gestation from 16 to 39 weeks were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound studies.Fast-imaging employing steady-state acquisition(FIESTA),single-shot fast spin echo(SSFSE)and T_1-weighted fast inversion recovery motion insensitive(FIRM)sequences were employed on the axial,coronal and sagittal planes of the fetal brain,thorax and abdomen,especially the thorax.Prenatal US and MR imaging findings were compared with postnatal diagnoses(13 fetuses)or autopsy(1 fetus).US,MR imaging and surgery were used for postnatal evaluation.Results Fourteen pregnant women(12 with a single fetus and 2 with twin fetuses)were studied.There were 12 fetuses(in 2 cases,being one of twins)with a left-sided and 2 with right-sided diaphragmatic hernias.For all cases,the prenatal MRI diagnosis Was correct when compared with postnatal diagnosis or autopsy.Two CDHs were missed and 2 were misdiagnosed by US.Intrathoracic herniated organs in 12 left CDH included the colon(n=1),the stomach(n=1),the bewel(n=5),or both the stomach and bowel(n=5).Intrathoracic herniated organs in 2 right CDH included the bowel(n=1),or the bowel and the right lobe of the liver(n=1).Conclusion Prenatal MRI is effective in the assessment of fetal congenital diaphragmatic hernia.
