Objective To present the CT and MRI findings of the fibrous dysplasia(FD) of the spine.Methods CT and MRI findings were retrospectively evaluated in 19 cases of FD of spine,all of which were confirmed pathologically.Nineteen patients underwent CT plain scanning(19/19) and 5 had enhanced CT scanning(5/19).Patients were also examined by MRI plain scan(11/11) or MRI enhanced scan (6/11).The location of tumors,the type of bone destruction,the boundary of lesions,internal intensity or signal,the enhancement pattern of lesions,and presence of compression fractures,spinal deformity were observed.Result Nine cases had monostotic FD,while 10 had polyostotic FD.In all the 49 lesions of 19 cases,13 lesions were located in the cervical vertebrae,23 lesions in the thoracic vertebrae,11 lesions in lumbar vertebrae,and 2 lesions in sacral vertebrae.Thirty-three lesions involved both vertebral body and appendix.Pure osteolysis were found in 26 lesions on CT examinations.Peripheral osteosclerosis rims (41/49) and expansive lesions(32/49) were seen.Residual bone crest(28/49) and ground-glass opacity(23/49)were noted.Different degrees of vertebral compression were found in 19 lesions.Five patients had spinal deformity.On T1WI,14 lesions showed intermediate or low signal,and 10 lesions presented as heterogeneous signal.On T2WI,6 lesions had low signal intensity,4 lesions were noted as hyperintensive,and 14 lesions presented as heterogeneous signal.Multiple fluid-fluid levels were found in 1 lesion.Low signal rims were seen in 14 lesions.Twenty lesions of 11 patients had significant enhancement.Conclusion Expansive pattern,ground-glass opacity,peripheral osteosclerosis rims and significant enhancement were helpful findings for the diagnosis of spinal FD.

Human DAB2 interaction protein (DAB2IP) is a novel member of Ras GTPase-activating protein family. It interacts directly with disabled-2 protein (DAB2/DOC2) which suppresses growth of cancers derived from different tissues, including mammary, prostate and ovarian cancers. DAB2IP was identified as an immediate downstream effector mediated by DAB2/DOC2. DAB2IP and DAB2/DOC2 form a unique protein complex that has a negative regulatory effect on the Ras-mediated signal pathway. It is demonstrated that DAB2IP is a tumor suppressor gene inactivated by methylation in several cancers. This article reviews the structure and biological functions of DAB2IP gene as well as its potential roles in carcinogenesis and evolution.

Objective　To study the visual electrophyological changes in　patients with pregnancy-induced hypertension syndrome(PIH).Methods　The visual evoked potentials (VEP) and electroretinogram (ERG) of 28 patients with PIH in 56 eyes were recorded.Results　The patients with PIH had pathologic visual electrophysiologic abnormalities. The VEP N75 peak latency significantly increased(P<0.05), and the ERG b wave latency in patients with PIH showed remarkable difference(P<0.05).Conclusion　Visual electrophysiological examination may be valuable in early diagnosis of retinal disfunction in patients with PIH.

Objective To isolate and culture meshenchymal stem cells from murine fetal liver.Methods flMSCs from mouse fetuses were isolated by adhering to plastic surface.Growth kinetics was determined by growth curve.Cell cycle and phenotype were analyzed by FACSan flow cytometry.Differentiation of adhering cells was induced and identified.Results Homogenous fibroblast-like cells were predominated in culture.The counting of flMSCs increased 2 fold after 24 hours and 83.76%?2.88% of flMSCs were in G0/G1 phases.flMSCs were CD44,CD29 positive but negative for the markers of hematopoietic cells such as CD45,CD11b.flMSCs were able to differentiate along adipogenic,chondrogenic and osteogenic pathways even after being passaged several times.ConclusionflMSCs can be isolated by their plastic-attachable property and can expand without losing their multiple differentiation potential in vitro.flMSCs may offer an appropriate cell source for stem cell therapy.

Objective:To understand the current situation of medical students' professional attitude,find out the exiting problems and put forward some corresponding suggestions.Methods:The medical students' professional attitude was investigated using questionnaire in Shanghai.FResults:Some medical students lacked of professional confidence;the students expected highly towards compensation benefit;the professional satisfaction was low.There existed a correlation between professional values,expect and satisfaction.Conclusions:Perfecting pre-service training is a necessary prerequisite to improve medical students' professional confidence;compensation benefit is one of the referred factors for medical students to choose an occupation;improving medical students' professional view is the foundation of long-term development of medical enterprise;the professional counterpart is the key to ensure medical students' professional satisfaction.

Objective To explore the clinical effect of Jieyu Anshen decoction combined with aripiprazole tablet in the treatment of chronic schizophrenia. Methods A total of 210 patients with chronic schizophrenia who were treated in our hospital from March 2015 to March 2017 were randomly divided into two groups,with 105 cases in each group. The control group was treated with aripiprazole tablet. The observation group was treated with Jieyu Anshen decoction combined with aripiprazole tablet. The treatment effect was observed and compared. Results There was no significant difference in the clinical condition between the two groups before treatment, and the improvement was more obvious in the observation group after treatment; The effective rate in the observation group (90.47％) was significantly higher than in the control group (80.0％), the difference was statistically significant (P<0.05). There was no significant difference in the safety of the two groups. Conclusion Jieyu Anshen Decoction combined with aripiprazole tablets in the treatment of chronic schizophrenia compared to conventional methods, can improve clinical efficacy, but also has good safety, it is worth clinical reference.

Objective:To discuss the ethical issues of living organ donation in China systematically and comprehensively,from the perspective of society,institution,family,individual and other level.Methods:Literature research and expert interviews were used as main research methods,supplemented by group discussion,in-depth interviews and other methods.Results:In the development of living organ donation in China,from the social level,the relevant laws and regulations,civic education and supporting measures had problems.From the institutional level,hospital human organ transplant ethics committee also had some deficiencies in staff composition,review capacity and supervision.On the individual level,donors and receptors of living organ donation and related medical personnel also had their own ethical dilemma.Conclusion:It is beneficial to fully promote living organ donation and fully realize the purpose of living organ transplantation for the benefit of mankind through solving the ethical issues from social,institutional and individual levels.

Objective: To investigate the diagnostic value of automatic breast volume system (ABVS) for breast carcinoma in clinical practice so as to use these reliable data to provide imaging reference for further therapy. Methods: 300 patients with suspected breast cancer were selected and the postoperative pathological examinations were chosen as the golden standard to implement screening. At the same time, 2 radiologists were selected to carry out the grading diagnoses of breast imaging reporting and data system (BI-RADS) so as to observe the consistency between diagnoses of ABVS and pathological results. Results: 210 patients were diagnosed as breast tumor by the post-operative pathological examination, and these patients included 89 malignant tumor (29.67%, 89/300). In these malignant cases, there were 42 cases were infiltrative ductal carcinoma, and its rate was 47.19% (42/89). Besides, there were 121 cases were benign tumor (40.33%), and the rate of patients with fibrosum adenoma (78 cases) was the highest in the 121 cases (64.46%, 78/121). And the diagnostic consistency of them was preferably (K=0.724). The sensitivity and specificity of ABVS in diagnosing breast carcinoma were 92.86% and 85.56%, respectively. Its positive predictive value and negative predictive value were 93.75% and 83.70%, respectively. And the Youden index was 0.78. Conclusion: ABVS has relatively high sensitivity and specificity, and the screening test has good authenticity and reproducibility. Therefore, it can provide a reliable basis for clinical diagnosis and treatment.
