Objective To investigate the correlation between AS160 hyperphosphorylation and 18Ffluorodeoxyglucose (18F-FDG) uptaking in invasive breast cancer.Methods Thirty-nine primary breast caner patients received PET/CT scan before operation and their maximum standard uptake values (SUVmax) were recorded.The levels of p-AS160 (Thr642) were detected using immunohistochemical method in breast cancer tissues.The association between p-AS160 (Thr642) levels and SUVmax was assessed using the Spearman nonparametric test.Results The 18F-FDG uptake of tumors of the 39 patients with primary breast caner was 6.1 ± 2.7 (SUVmax).There was one false negative case in PET/CT scan imaging,compared with postoperative pathologic result.The positive rate of p-AS160 (Thr642) was 76.9％,and it was positively correlated with SUVmax (r =0.672,P ＜ 0.001).Conclusion AS160 plays a significant role in the glucose metablism of breast cancer tissues and its hyperphosphorylation may contribute to the increased uptaking of glucose in patients with breast cancer.

Objective:To investigate the therapeutic effect and signaling pathway of ginsenoside Rb1 on myocardial injury in mice with Kawasaki disease.Methods:BALB/C mice aged 5-6 weeks were randomly divided into control group, model group, aspirin group, ginsenoside Rb1 low dose group(50 mg/kg) and high dose group(100 mg/kg), with 12 mice in each group.Except the control group, other groups were treated with intermittent intraperitoneal injection of 10% bovine serum albumin saline solution to induce Kawasaki disease myocardial injury pathological model with a total of 6 days(twice a day); aspirin group, Rb1 low and high-dose group were given corresponding drugs by gavage for 20 days after modeling.The pathological changes of myocardial tissue were observed by hematoxylin eosin staining.The levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), interleukin-6(IL-6) and cardiac troponin I(cTnI) in serum and myocardial tissue were detected by ELISA.The activities of creatine kinase(CK), creatine kinase isoenzyme(CK-MB), lactate dehydrogenase(LDH), α-hydroxybutyrate dehydrogenase(α-HBDH) and aspartate aminotransferase(AST) in serum were detected by enzyme coupling method.The expression levels of janus kinase 2/signal transducer and activator of transcription 3(JAK2/STAT3) signaling pathway related proteins in myocardial tissue were detected by Western blot.Results:High dose of Rb1 significantly improved myocardial fiber rupture and tear, inflammatory infiltration and necrosis induced by myocardial injury in model group.ELISA results showed that, compared with the model group, high-dose Rb1 could significantly inhibit the high expression of tumor necrosis factor-α, interleukin-1β, interleukin-6, which were restored to the level of the control group, and there was a dose-dependent relationship between the low and high-dose groups( P<0.05). The results of enzyme coupling method showed that creatine kinase, creatine kinase isoenzyme-MB, lactate dehydrogenase, α-hydroxybutyrate dehydrogenase, and aspartate aminotrasferase in Rb1 high-dose group were restored to the level in control group, and there was a dose-dependent relationship between low and high-dose group( P<0.05). At the same time, compared with model group, Rb1 high-dose group significantly down regulated the expression level of cardiac troponin I( P<0.05). Western blot results showed that, compared with the model group, Rb1 significantly increased the relative expression levels of p-JAK2/JAK2, p-STAT3/STAT3 and B-cell lymphoma-2(Bcl-2)/β-actin, and significantly decreased the expression levels of Cleaved caspase-3/β-actin in a dose-dependent manner( P<0.05). Conclusion:Ginsenoside Rb1 can effectively reduce the myocardial injury induced by Kawasaki disease mice.The high-dose group of Rb1 can recover to the level of the control group, and the curative effect is related to the dosage of Rb1.Ginsenoside Rb1 may activate JAK2/STAT3/Bcl-2 signaling pathway, thus down regulate the expression of Cleaved caspase-3, and inhibit cardiomyocyte apoptosis and inflammation.

OBJECTIVE: To evaluate the instructional effect of Multi-slice (MSCT) in the cochlear implantation pre- and post-operatively, and to contrast the image feature between the X-ray and the MSCT three-dimensional reconstruction of inner ear with implanted electrode. METHOD: Twenty-four cochlear implant (MEDEL Combi 40+) recipients,in No. 1 Hospital of China Medical University from January to October 2014, were involved in this study. Among them, 18 were male and 6 female,with an average age of 4 years. MSCT and three dimensional reconstruction of inner ear were performed in all of the 24 implanted inner ears pre- and post-operatively. And X-ray plain film were examined by using 60° lateral oblique position postoperatively. All data of the spiral CT scan with axial 1 mm image slices were transferred to workstation for three-dimensional reconstruction (direct volume rendering) of the inner ear. RESULT: In 1 of the 24 cases, preoperative three-dimensional reconstruction CT scan reveal that the length of the cochlear was shorter than the electrode. And this was confirmed by MSCT postoperatively that the electrode couldn't be inserted by full length. The insertion depth of the electrode can be evaluated directly by MSCT. Moreover, each of the electrode pairs can be identified clearly. CONCLUSION MSCT plays an indispensable role in the preoperative evaluation of cochlear implantation. Postoperative evaluation by three-dimensional reconstruction of inner ear provide more accurate image to show the electrode insertion depth in the cochlea. MSCT combined with curved planar reformation to measure cochlear length could provide guidance in choosing the more adaptive electrode. And MSCT is superior to DR in demonstration of electrode postoperatively.

Objective To investigate the ultrasound characteristics of congenital cystic adenomatoid malformation (CCAM). Methods The ultrasonographic features of 21 cases of fetal CCAM confirmed by prenatal ultrasound were analyzed. And ultrasound ifndings were compared with the postnatal thoracic computed tomography (CT), surgical result and follow-up data. Results (1) Prenatal ultrasonographic ifndings:2 cases of CCAM typeⅠ(10%, 2/21), 13 cases of typeⅡ(62%, 13/21), and 6 cases of typeⅢ(28%, 6/21). Of them, 95%(20/21) lesions were located in unilateral thorax, while 5%(1/21) in bilateral thorax. CCAM was ifrst detected at 18th-25th gestational week with a median of 22nd week. The CVR was<1.6 and>1.6 in 16 (76%, 16/21) and 5 (24%, 5/21) cases respectively. After reaching the maximum volume, the size of mass remained stable in 8 cases and regressed in 13 cases with even complete remission in 5 cases. There were mediastinal shift in 19 fetuses (90%, 19/21), polyhydramnios in 6, and concomitant structural abnormalities in 3 cases such as pulmonary sequestration, diaphragmatic hernia and fetal hydrops. (2) Clinical outcomes:15 newborns were conifrmed as CCAM by CT, in which 9 cases underwent surgical resection. One case was conifrmed by autopsy. Nineteen cases showed good prognosis. Whereas 1 pregnancy with fetal hydrops was terminated, and 1 fetus with diaphragmatic hernia died after birth. Conclusions Dynamic prenatal ultrasound assessment is the key factor in prognosis prediction of fetal CCAM. CCAM without other structural abnormalities has a good outcome.

Objective To study radiographic features of atypical adenomatous hyperplasia(AAH) of lung and correlate them with their pathologic findings,so as to improve the imaging diagnose.Methods The imaging features of 8 patients with pathology-proved AAH were reviewed.All patients were women with age ranging from 35 to 74 years.All cases had chest radiography and HRCT.The radiographic findings were studied retrospectively and correlated with those of pat hology.Results On chest X-ray,the foci in five patients presented as nodule-like area of a bit high attenuation,while the chest radiograph in the other three patients were negative.On HRCT,all 8 patients presented as non-solid nodules.All lesions were round or oval shaped with well-defined margin(n=4)or poor-defined margin(n=3).The greatest dimension of the lesions ranged from 5.0 mm to 20.0 mm.Their CT value ranged from-362.7 HU to-485.6 HU,the mean CT value was(-423.0?47.0)HU.Air bronchograms and/or bubbles were seen in 5 lesions.Coarse spiculation and pleural tag was not seen in any lesion.Before operation,all the nodules did not change in size over a follow-up period from one month to six months.Pathologic findings showed atypical epithelial cell proliferation along thickened alveolar septa without alveolar collapse.Conclusion AAH should be considered in cases with the following features:(1)nodules are found in lung cancer screening or incidentally detected;(2)the diameter of the nodule is usually less than 10 mm;(3)the lesion presented as non-solid nodule on HRCT,air bronchogram and/or bubble sign can be seen;(4)no coarse spiculation and plural tag was seen.

Objective To investigate the surgical diagnosis and treatment of late vitamin K deficiency intracranial hemorrhage caused by biliary atresia. Methods Clinical data of six cases of biliary atresia with late vitamin K deficiency intracranial hemorrhage were collected in the Department of Neurosurgery of Tianjin Children’s Hospital from January 2000 to December 2013. Data were analyzed to identify the biliary atresia as soon as possible in the treatment of intracranial hemorrhage and prolonged jaundice in children. Results Six cases (1 male, 5 female), mean age was (16.0±2.6) days, and were treated with external drainage of intracranial hematoma and infusion therapy. In the treatment, children were found jaundice exacerbation and doubted about biliary atresia. After consultation by general surgeons, children were transferred to the department of general surgery for further treatment at an average age of (29.1±1.2) days, and were diagnosed as biliary atresia by intraoperative cholangiography. Conclusion Pediatric neurosurgeon should have a sufficient understanding and make an early diagnosis to late vitamin K deficiency intracranial hemorrhage caused by biliary atresia, to avoid delaying the optimal treatment time of biliary atresia.
