Objective To study the correlation between scan orientation and the detectability of rotator cuff injury.Methods Different scan orientations of magnetic resonance imaging of the rotator cuff injury were analyzed in high magnetic field in 103 patients.Results The supraspinatus tendon and signal abnormities were obtained in 103 patients,the infraspinatus tendon and signal abnormities in 53 patients,subscapular tendon and signal abnormities in 18 patients,knolls tendon and signal abnormities in 15 patients.The oblique coronal MR imaging was clearest in supraspinatus tendon,while at the axial images was clearest in infraspinatus tendon.Conclusion Rotator cuff and the surrounding tissue injury could be clearly scanned in high magnetic field,the detectability of rotator cuff injury depended on different scan orientations of magnetic resonance imaging.

To evaluate the efficacy of HbA1C in diagnosing diabetes in subjects with primary hypertension.The results demonstrated that the area under the reciever operating characteristic ( ROC ) curve was 0.895,with corresponding sensitivity of 85.4％,and specificity of 82.2％,when the optimal cutpoint of HbA1C in diagnosing diabetes was 6.0％.Our study suggested that HbA1C ≥6.0％ can be used efficiently in diagnosing diabetes in patients with primary hypertension.

Sphingolipids, especially ceramide and S1P, are structural components of biological membranes and bioactive molecules which participate in diverse cellular activities such as cell division, differentiation, gene expression and apoptosis. Emerging evidence demonstrates the role of sphingolipids in hepatocellular death, which contributes to the progression of several liver diseases including ischaemia-reperfusion liver injury, steatohepatitis or hepatocarcinogenesis. Furthermore, some data indicate that the accumulation of some sphingolipids contributes to the hepatic dysfunctions. Hence, understanding of sphingolipid may open up a novel therapeutic avenue to liver diseases. This review focuses on the progress in the sphingolipid metabolic pathway with a focus on hepatic diseases and drugs targeting the sphingolipid pathway.

Background Glial cells perform specialized function in many aspects of the development,homeostasis,and function of neurons.Retinal ganglion cells (RGCs)and glia interactions are critically important in glaucomatous neurodegeneration.However,the precise mechanisms of glial activation and ganglion cells damage are still remained unclear. Objective This study was to assess the early responses of glial cells in the retina,optic nerve and optic chiasm in rat models of acute high intraocular pressure (IOP),and to examine the expression of nestin,a neuronal progenitor marker,in the reactive glias. Methods Acute high IOP of 110 mmHg was induced in the right eyes of 6 clean adult female Wistar rats by infusing normal saline solution into the anterior chamber for 60 minutes.Three normal matched Wistar rats were used as controls.The rats were sacrificed by overanaesthesia and sections of retina,optic nerve and optic chiasm were collected on 3 days and 7 days after the injection.Rat retina was examined by Nissl staining to illustrate the gross structure changes.Loss of axons of RGCs in the optic nerve was assessed by immunostaining of β Ⅲ-tubulin.Double labeling of glia] fibrillary acidic protein (GFAP) and nestin was performed in sections of retina,optic nerve and optic chiasm to evaluate the glial responses.The use of the animals complied with Statement of Animal Ethic Committee of Peking University Third Hospital. Results In control rats,GFAP-positive glial cells were observed in the retina,optic nerve and optic chiasm,where only weak positive response for nestin was noticed.Three days after acute IOP elevation,thickness of inner plexus form layer was significantlydecreased in comparison with the control rats.A loss of 46％ RGCs was found in the rats with ocular hypertension.Obvious increase of GFAP expression was displayed in the retina,and processes of GFAP-positive glia cells extended into outer retina accompanied with significant up regulation of nestin.Axons in the optic nerve demonstrated a tendency of degeneration.Nestin expression increased significantly in the GFAP-positive glias in the optic nerve.Cross-sectional area of optic chiasm corresponding to the injured retina decreased relative to its countcrpart.Astrocyte like GFAP and nestin-colabeled glials were observed in this part of optic chiasm.The pathological changes of the retina,optic nerve and optic chiasm in hypertensive eyes aggravated on 7 days. Conclusions Acute ocular hypertension induce early onset of RGCs loss and axon degeneration.Neuronal injury is accompanied with glial reaction.Reactive glial cells express neuronal progenitor markers.The structural changes of the optic nerve and optic chiasm occur simultaneously with the high IOP.

Objective To investigate the characteristics and relationship of cognitive function and resting state functional magnetic resonance imaging(fMRI) amplitude of low-frequency fluctuations (ALFF)in childhood and adolescence-first-onset obsessive-compulsive disorder(OCD).Methods Twenty-four childhood and adolescence-first-onset OCD patients (patient group) and thirty-three age/gender/education-matched healthy controls (healthy control group) were enrolled in this study.The participants' cognitive function was tested with trail making test (TMT),symbol coding,Hopkins verbal learning test-revised (HVLT-R),brief visuospatial memory test-revised (BVMT-R),verbal fluency test (VF),digital span test,maze test and Stroop test.Then a resting-state fMRI scan was conducted for each participant.Amplitude of low-frequency fluctuation approach was used to explore the differences of resting-state brain function between patients and controls,and analyze the significant brain regions by adopting t test.The cognitive functions of patients and healthy control group in the significant brain regions were compared by using Pearson correlation analysis.Results The patient group had lower scores than healthy control group in symbol coding,BVMT-R and digital span test,and the differences were statistically significant [(45.24 ± 10.32)scores vs.(56.85 ± 9.57) scores,(21.94 ± 6.99) scores vs.(30.58 ± 3.92) scores,(64.06 ± 20.00) scores vs.(78.03 ±18.08) scores;t =3.96,4.90,2.50;all P ＜ 0.05].Corrected by Alphasim,patient group showed significantly increased ALFF in the left and fight temporal lobe,left and fight posterior lobe of cerebellum,right middle temporal gyrus,but ALFF decreased in the area of left and right lenticula,left putamen compared with the healthy control group (all P ＜ 0.05).The patients group showed that TMT scores were positively correlated with the value of ALFF in the right temporal lobe (r =0.67),and color scores were positively correlated with the value of ALFF in the right middle temporal gyrus (r =0.53),but colour scores were negatively correlated with the value of ALFF in the right tcmporal lobe (r =-0.54);the healthy control group showed that BVMT-R and digital span test scores were positively correlated with the value of ALFF in the left temporal lobe (r =0.47,0.41),but digital span test scores were negatively correlated with the value of ALFF in the right temporal lobe (r =-0.49),and colour scores were negatively correlated with the value of ALFF in the left temporal lobe (r =-0.35),while word and color-word scores were negatively correlated with the value of ALFF in the right middle temporal gyrus (r =-0.39,-0.36);the correlation coefficient above had statistical significance (all P ＜ 0.05).Conclusions The childhood and adolescence-first-onset OCD patients had cognitive impairment,including speed of processing,visual learning and memory,working memory;and the patients showed abnormal spontaneous neural activity at some brain regions.The cognitive dysfunction may be associated with abnormal spontaneous neuronal activity in childhood and adolescence-first-onset OCD.
