Objective To study the effects of rehabilitation training on the regeneration of nerve cells in rats after intracerebral hemorrhage (ICH).Methods A total of 75 male SD rats were randomized into a training group,a control group and a sham operated group,25 rats/group.The ICH models were induced by stereotactical injection of collagenase type Ⅶ into the globus pallidus.The training group was trained with grasp,balancing and rotating exercise every day,the control group was restricted to their cages,and the sham operated group received normal saline injections.Each group was further subdivided into 1,4,7,14 and 28 day subgroups.Neurological function was measured in each group.Bromodeoxyuridine (BrdU) was used to label S phase cells,immunohistochemical single and double staining with antibodies against BrdU,microtubal-associated protein (MAP) and neuronal nuclei (NeuN) were used to determine neuronal proliferation,migration and differentiation in the subventricular zone ( SVZ ) and subgranular zone (SGZ) in the training and control groups.Results The motor function scores of the animals in the rehabilitation group were significantly lower than those of the control group.Proliferative BrdU + cells of the SVZ and SGZ in the control group rats were clearly less than those in the rehabilitation training rats at all time points.The results of the immunohistochemical double staining indicated that one week after ICH BrdU +/MAP + cells in the SVZ had increased significantly in the training group compared to the control group,and then decreased two weeks later.At the same time,BrdU +/MAP cells were found in the striatal boundary on the hemorrhage side,in numbers up to 8 times that in the control group.In the rehabilitation group striatal neuron differentiation on the hemorrhage side was 2 to 3 times that in the control group.Conclusion Rehabilitative training can enhance nerve cell proliferation,regeneration and neuron migration after ICH.

Obesity has been identified as one of the risk factors for malignant neoplasms,such as breast cancer.Epidemiological data shows that obesity is closely related to the development and progression of breast cancer.The pathogenesis may involve in estrogen,insulin,leptin,adiponectin and inflammation factors.Therefore,maintain normal body weight may contribute to the prevention of breast cancer.

Objective To discuss the appearances of focal nodular hyperplasia(FNH) of the liver on the muhiphase helical CT scanning, and to improve its diagnostic accuracy with CT. Methods Helical CT scanning of pre- and post- contrast arterial phase,portal venous phase and delayed phase was performed in 10 cases with surgically and pathologically proved FNH. Results On pre- contrast scans,9 of 11 FNH lesions were hypodense(either homo-geneous or non-homogeneous), the other two lesions were isodense. On the arterial phase scans, all lesions were markedly and homogeneously enhanced,except for the central scar area. Tortuous and dilated arteries were seen at the center or peripheral area in 3 out of 11 lesions. On the portal phase and delayed phase scans ,4 of 11 lesions turned to isedanse of slightly hypodense,7 lesions remained slightly hyperdense. Central scar was found in 8 FNH lesions ,2 of them showed no enhancement while the other six demonstrated late enhancement. Conclusion Mulfiphase helical CT scanning can fully reflect the blood supplying and pathologic features of FNH, and it is of great value in diagnosing and differentiating FNH.

Objective To investigate the X-ray,CT and MRI features of peripheral primitive neuroectodermal tumors (pPNETs).Methods 14 patients were pathologically diagnosed with pPNETs.The imaging of X-ray (twelve image),Computed Tomography(eleven image) and Magnetic Resonance Imaging(five image) were retrospectively analyzed.Results Of 14 patients,there were two sites of tumour:soft tissue( eight patients) and bones( six patients).For tumoura of the soft tissue region,the appearance of X-ray and CT imaging showed equal or lower density soft mass without dear boundary.In some cases,tumours invaded adjacent bones.The appearance of MRI imaging showed large heterogeneous masses inside soft tissue without clear boundary.Tumours displaced adjacent cortical bone and cavitas medullaris.All masses were heterogeneous enhancement on contrast images.For tumours of bone region,X-ray and CT scan showed large scale osteolysis osteoclasia in bone surrounding with soft tissue masses of various size.The lesions were equal or lower signal on T1 WI.All masses were intermediate or hyperintense signal with heterogeneous midrange or obvious enhancement on T2WI.Conclusion Imaging characteristics of pPNETs were described.X-ray,CT and MRI were useful in understanding the property,extent and staging of tumor and very useful in the diagnosis.

This paper introduces the background, implication and construction of the county health services community (County medical alliance) model in Anhui Province under the background of new medical reform,and briefly introduces the relationship between medical insurance, enhancing the ability to upgrade and standardize services and medical treatment integration of the typical experience.It also analyses the challenges faced in the construction of medical syndicate, such as the mechanism of regional environmental restriction, compensation and assessment mechanisms which have not been established yet, and the sustainable development of information technology that has lagged behind, and put forward the policy suggestion to improve the construction of medical community, with a view to providing reference for the next work.

To introduce the development of myelodysplastic syndrome network course.

Objective To explore the characteristics of subjective quality of life and family environment in children with tic disorder (TD) combined with and without attention deficit hyperactivity disorder (ADHD). Methods The Inventory of Subjective Life Quality (ISLQ) for Child and Adolescent and Family Environment Scale-Chinese Version (FES-CV) were used to assess the subjective quality of life and family environment in 60 children with TD combined with ADHD (observation group) and 60 children with TD not combined with ADHD (control group). Results The scores in peer interaction, school life, self-cognition, depression experience, overall satisfaction of the observation group were lower than the control group (P<0.05) in ISLQ; the scores in intellectual-cultural orientation, cohesion and organization of the observation group were lower than the control group (P<0.05) in FES-CV. Conclusion Children with TD combined with ADHD had low subjective quality of life and poor family environment.

Technological improvement for microorgnism isolation is important since isolation provides substantial materials for the exploitation of new microbial resources. In this study, a new approach, dispersion and differential cetrifugation (DDC), was applied in the isolation of acidophilic and acidoduric streptomycetes from 12 acid soil samples. Contrast with traditional method, the new approach yielded satisfying results with 2 - 20 times isolation efficiency and good selectivity. 45 representatives out of 249 streptomycetes isolates, which belonged to 12 color groups, showed morphology and cell wall type consistent with streptomycetes. The optimum pH range for their growth were between pH 4.5 - 5.5. It is proved that we succeeded in the rare-streptomycetes isolation using DDC approach.
