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 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 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.

Objectiv To explore the effects of chromium (Ⅵ) on the levels of malondialdehyde (MDA), the final product of lipid peroxidation in peripheral blood of mice and the micronucleus rate of polychromatic erythrocytes (PCE) in peripheral blood. Method 60 Kunming mice were divided randomly into 6 groups averagely. 4 groups were selected as exposure groups which were exposed to 10.27, 13.83, 20.74, 41.48 mg/kg calcium chromate by oral perfusion, one time per day, for 6 days. The negative and positive control group was exposed to distilled water and cyclophos phamide (40 mg/kg) respectively. After exposure, the levels of MDA and micronucleus rates of PCE were determined. Results Significant increases of the levels of MDA and the micronucleus rates of PCE in peripheral blood of mice were observed, which were associated with the increases of the exposure doses of chromium (Ⅵ). Significant positive correlation was observed between the micronucleus rates of PCEs (x) and MDA(nmol/ml) levels (y) in peripheral blood (y=3.705+930x,r=0.958, P

Objective To study the protective mechanism of mild hypothermia from severe traumatic brain injury (sTBI). Methods 160 cases with sTBI were treated under normothermia (NT group, n=80) and mild hypothermia (HT group, n=80) respectively. Their serum level of anti-brain antibody (ABAb) was measured with ELISA, cerebral haemodynamics with transcranial Doppler, and intracranial pressure (ICP) with ICP monitor 1 d, 3 d, 5 d, 7 d and 14 d after injury, while they were assessed with Glasgow coma scale (GCS) and Glasgow outcome scale (GOS). Results The level of ABAb was lower in HT group than in NT group (P<0.05) at every point. The scores of GCS increased (P<0.05), and the volume of systole, mean and pulse index improved more in HT group 5 d after injury (P<0.01). The ICP was lower in HT group 3 d after injury (P<0.01). The score of GOS was better in HT group than in NT group when discharged (P<0.05). Conclusion Mild hypothermia can reduce the level of serum anti-brain antibody, improve cerebral haemodynamics, decrease ICP and improve the prognosis in patients with sTBl.
