Magnetic resonance imaging (MRI),a commonly used imaging technique,has been extensively investigated in lung cancer diagnosis and staging.Many studies have demonstrated that MRI can be used for the differential diagnosis of benign and malignant pulmonary nodules and for the screening of lung cancer; it also has important value in TNM staging of non-small cell lung cancer (NSCLC),with equivalent sensitivity and specificity to 18F-fluorodeoxyglucose (18F-FDG) PET-CT,which suggests that MRI can be used as an alternative imaging modality in noninvasive diagnosis and staging of NSCLC.

Objective:To evaluate the etiology,elinic characteristics,diagnosis and treatments of spontaneous perforation of the bile duct in children. Methods:The clinical data of eight children with spontaneous perforation of the bile duct between 1998 -2006 were analyzed retrospectively. Results:5 of 8 cases were diagnosed bile duct perforativn before operation,all the patients recovered favorably after T-tube and pelvic drainage. 3 children complicated with choledochal cyst were cured afterⅡstage radical operation. Conclusions:the etiology of spontaneous perforation of the bile duct in children is unclear, panereaticobiliary confluence malfunction (PBCM) maybe the main reason. Peritoneocentesis is very important to the diagnosis, which is difficult in child preoperatively. The effective surgical treatments are T-tube and pelvic drainage. The children complicated with PBCM needⅡstage radical operation,and long term follow up are necessary for the children present with spontaneous perforation of the bile duct without PBCM.

Objective:To investigate the effect of ultrasound on the ultrastructure and expression of P-gp of Neuroblastoma cell in order to discuss the mechanisms of ultrasound affecting the chemotherapeutic sensitivity of SK-N-SH cell. Methods:The SK-N-SH cells were divided into the experimental group and the control group. In the experimental group,the cell suspensions were exposed to ultrasound irradiation. In the control group,the cell suspensions were exposed to sham irradiation . The changes of ultrastructure of tumor cells were observed by scanning electron microscope and the expression of P-gp in two groups were detected. Results:(1) In the pictures took by scanning electron microscope,we found that: the configuration of tumor cell changed and there were some holes of different diameters on the cell membrane and the numbers of microvillus reduced or disappeared after ultrasound irradiation.(2) The result of immunocytochemisty showed the expression rate of P-gp in SK-N-SH cells in the control group was 56.23%?9.86% vs 34.86%?6.19% in the experimental group (P

Objective To summarize the perioperative nursing experience in nursing children with formaral angulation deformity treated with sreminobicular crib external fixator. Method The clinical data of 15 children with formaral angulation deformity treated with sreminobicular crib external fixator were reviewed. Results All 15 children got recovered, with the femora extended by 4~9 cm. After operation, all of them were affected by knee flexion dysfunction and foot drop to varied extents, which were improved satisfactorily after systematic training. Conclusions The systematic and progressive training can prevent knee flexion dysfunction and foot drop. Careful observation and effective nursing play an important role in the treatment of formaral angulation deformity.

Objective To study the ultrasonic characteristics of fetal cutaneous hemangioma and the association with perinatal outcomes.Methods Five fetuses with cutaneous hemangioma were detected by gray-scale and color Doppler ultrasound,compared with the result of pathology and hematology examinations after birth.Results Of the 5 cases diagnosed by ultrasound,3 had arteriovenous fistulas.In these 3 cases two fetuses developed high-output cardiac failure,and one developed cardiac insufficiency and thrombocytopenia.Finally one fetus was induced,one fetus died in the uterus and one neonate survived.The other two fetuses who had small tumors diagnosed by ultrasound did not develop any perinatal complications, and the neonates had favourable prognosis.Conclusions Massive hemangiomas are frequently associated with life-threatening complications such as high-output heart failure,thrombocytopenia and disseminated intravascular coagulopathy(Kasabach-Merritt syndrome).

Meckel′s diverticulum is the most common congenital anomaly of the gastrointestinal tract. Most ca-ses are asymptomatic,while it can be symptomatic when complications happened,its complications often expressed as hematochezia,abdominal pain,vomit,fever,and so on. When signs or symptoms arise from a Meckel′s diverticulum, morbidity and mortality will increase. So make a definite diagnosis of the diverticulum play an important role in the treatment of Meckel′s diverticulum. In this essay,now illustrate the meaning of imaging examination about the diagnosis of Meckel′s diverticulum,wish to make a diagnosis as soon as possible.

Objective To study the correlation between hand, foot and mouth disease (HFMD) in lung-spleen damp-heat syndrome, syndrome of stagnation and steaming due to damp-heat, and syndrome of stirring wind due to toxic-heat with IL-6, PCT, CRP, CD3+, CD4+, CD8+ and NK cells.Methods Ninety patients with HFMD were randomly selected, dividing into lung-spleen damp-heat syndrome, syndrome of stagnation and steaming due to damp-heat, and syndrome of stirring wind due to toxic-heat, 30 cases for each syndrome. IL-6, PCT, CRP, CD3+, CD4+, CD8+ and NK cells were detected, and the distribution of above indicators in the three syndromes were analyzed.Results Levels of IL-6, PCT and CRP in syndrome of stirring wind due to toxic-heat were significantly higher than those in lung-spleen damp-heat syndrome and syndrome of stagnation and steaming due to damp-heat, with statistical significance (P<0.01); There was statistical significance in absolute value counting of CD3+, CD4+, CD8+ and NK cells among the three syndromes (P<0.01); There was statistical significance in the percentage of CD3+ cells in syndrome of stirring wind due to toxic-heat and lung-spleen damp-heat syndrome (P<0.01) and syndrome of stagnation and steaming due to damp-heat (P<0.05); There was statistical significance in the percentage of CD4+ cells syndrome of stirring wind due to toxic-heat and lung-spleen damp-heat syndrome (P<0.05) and syndrome of stagnation and steaming due to damp-heat (P<0.01); There was statistical significance in the percentages of CD8+ and NK cells in the three syndromes (P<0.01).Conclusion Proinflammatory cytokines, proinflammatory markers, and T cell sub-group related to HFMD in lung-spleen damp-heat syndrome, syndrome of stagnation and steaming due to damp-heat, syndrome of stirring wind due to toxic-heat are not only correlative with morbidity, but also with the severity of diseases and prognosis, which can relatively effectively evaluate the state of diseases and judge prognosis.

Objective To study the clinical characteristics and imaging features of alien hand syndrome (AHS). Methods We retrospectively analyzed the clinical data of 3 typical cases in our hospital,in comparison with case reports and reviews of domestic and foreign during the past decade. Result All 3 patients showed corpus callosum lesions from CT or MRI detections. The symptoms of the patients included alien hand sign , abnormal involuntary movements, intermanual conflict of upper limbs, and so on. And the patients accompanied with emotional and cognitive changes. Two of them were improved in different degrees after treatment. Conclusion AHS was a complex disease. The diagnosis of this syndrome was based on the advanced neuroimaging. There was still no well established treatment for AHS.
