BACKGROUND:Thyroid-stimulating hormone receptor is an autoantigen shared by thyroid follicuar cells and ocular orbital tissues,and cytokines plays an important role on the pathogenesis of Graves ophthalmopathy(GO) . It is still a puzzle that the relation of cytokines and thyroid-stimulating hormone receptor in the pathogenesis of GO. OBJECTIVE:To study the influence of various cytokines on the expression of thyroid-stimulating hormone receptor in the process of adipogenesis of in vitro cultured orbital adipose cells in GO patients. DESIGN,TIME AND SETTING:A single sample observation was carried out in the Central Laboratory,Department of Ophthalmology,Sun Yat-sen University(Guangzhou,Guangdong,Province) from September 2003 to March 2004. MATERIALS:Orbital adipose cells were obtained from eight serious GO patients undergoing orbital decompression. Recombinant human interleukin 2(IL-2) ,IL-4,IL-6,IL-10,and interferon ?(IFN-?) were purchased from PEORO TECH EC Company. METHODS:Orbital adipose cells were cultured and treated by groups. IL-2,IL-4,IL-6,IL-10 and IFN-? was added to the culture media in the experimental group,while no any cytokine was given in the untreated group,and orbital adipose cells were primarily cultured in the control group. The cells were all collected twelve days later. MAIN OUTCOME MEASURES:The expression of thyroid-stimulating hormone receptor was examined with reverse transcriptase-polymerase chain reaction,and the content of cyclic adenosine monophosphate was measured with simultaneous radioimmunoassay. The quantitation of adipose in cells was detected by staining intracytoplasmic lipids with oil red O. RESULTS:The expression of thyroid-stimulating hormone receptor was significantly higher in cells treated with IL-2,IL-4,IL-6 and IL-10 than that in the untreated cells and in the cells treated with IFN-?. Treatment of GO orbital adipose cells with IL-2,IL-4,IL-6 and IL-10 during differentiation resulted in significantly greater cyclic adenosine monophosphate production by different degrees. The highest production achieved in the treatment with IL-6,which was two times as many as control group. The cyclic adenosine monophosphate production was significantly lower in the cells treated with IFN-? than in the untreated cells. CONCLUSION:IL-6,IL-4 and IL-10 can upregulate the expression of thyroid-stimulating hormone receptor in the orbital adipose cells of GO patients,and stimulate adipose differentiation. Conversely,IFN-? can restrain this process.

The situation of the ongoing fifth epidemic (beginning October,2016) of human infection with avian influenza A (H7N9) virus are more serious than the first four ones.As of March 8,2017,the fifth epidemic reported 40.00％ of the cumulative cases.Recently,the pathogenic study reported two new human infections in Guangdong with an influenza A(H7N9)virus strain for which gene sequencing analysis revealed mutations in the haemagglutinin (HA) gene that resulted in the insertion of basic amino acids at the cleavage site of this protein,known to confer increased pathogenicity in chickens.However,most strains show no obvious difference in pathogenic characteristics compared with those detected during the first four waves.Although epidemiological studies showed that 3 clusters with limited human-to-human transmission have been investigated during the current wave,there are no indications of sustained person-to-person spread.Based on epidemic analysis and risk assessment results,it's likely that human infections with H7N9 virus will continue to occur in China,but epidemiological and pathogenic analysis suggested that it's unlikely to have a continued transmission of this virus.Profound public health significance would be presented by strengthening etiology and epidemiology studies of avian influenza A(H7N9) virus.

Magnetic resonance (MR) images can be used to detect lesions in the brains of patients with multiple sclerosis (MS). An automatic method is presented for segmentation of MS lesions using multispectral MR images in this paper. Firstly, a Pd-w image is subtracted from its corresponding T1-w images to get an image in which the cerebral spinal fluid (CSF) is enhanced. Secondly, based on kernel fuzzy c-means clustering (KFCM) algorithm, the enhanced image and the corresponding T2-w image are segmented respectively to extract the CSF region and the CSF-MS lesions combinatoin region. A raw MS lesions image is obtained by subtracting the CSF region from CSF-MS region. Thirdly, based on applying median filter and thresholding to the raw image, the MS lesions were detected finally. Results were tested on BrainWeb images and evaluated with Dice similarity coefficient (DSC), sensitivity (Sens), specificity (Spec) and accuracy (Acc). The testing results were satisfactory.

BACKGROUND:Studies have shown that bone marrow mesenchymal stem cells under certain conditions can differentiate into nerve cells. Bone marrow mesenchymal stem celltransplantation can rebuild nervous system function and improve functional disorders in patients. Glycosides of cistanche also have a protective effect against nerve cellinjury. Their combination has been less reported. OBJECTIVE:To observe the effectiveness of Cistanche deserticola and bone marrow mesenchymal stem celltransplantation on spinal cord injury in rats. METHODS:Fifty adult Wistar rats with spinal cord injury were randomly divided into four group:a Cistanche deserticola group (intragastric administration of 20 mL/kg Cistanche deserticola concentrated solution per day), a celltransplantation group (10μL of 1×108/L bone marrow mesenchymal stem cellsuspension), a combination group (10μL of 1×108/L bone marrow mesenchymal stem cellsuspension+intragastric administration of 20 mL/kg Cistanche deserticola concentrated solution per day) and a control group (intragastric administration of 20 mL/kg normal saline per day). The intragastric administration lasted for 30 days in each group. RESULTS AND CONCLUSION:After 30 days of treatment, the expression of Nestin was significantly higher in the combination group than the other groups. After 12 weeks, Basso, Beattie, and Bresnahan scores was significantly higher in the combination group than the other groups (P<0.05);somatosensory and motor evoked potential latencies were also improve significantly in the combination group compared with the other groups (P<0.05). These findings indicate that oral administration of Cistanche deserticola combined with bone marrow mesenchymal stem cells can significantly improve the motor and neurophysiological function of spinal cord injury rats. Cistanche deserticola can improve the survival of transplanted bone marrow mesenchymal stem cells in rats with spinal cord injury.

Objective To develop an indicator system for evaluating midwifery quality. Methods Guided by the latest evidence-based framework of midwifery quality,based on indicator selection principle,the indicator system for evaluating midwifery quality was preliminarily developed by literature review,expert meeting,theoretical analysis and expert consultation,for further validation through large-scale Delphi method.

In order to understand the alcohol's toxicity to the quantitative alternations of synapses in mouse visual cortex, the expression of synaptophysin after prenatal alcohol exposure was investigated. In present study, the experimental mice at P0, P7, P14 and P30 were grouped, as control, 2 g x kg(-1) alcohol treatment and 4 g x kg(-1) alcohol treatment. The pre-synaptic elements which were used to represent synapses were marked with synaptophysin (a synaptic vesicle associated protein) by immunocytochemistry technique. The synaptophysin positive boutons in layer VI of visual cortex were imaged under laser confocal microscope. With stereological methods, the number cal density of synapse in visual cortex was calculated in different groups at various ages. Moreover, Western blotting was carried out to detect the expression of synaptophysin in visual cortex. The results showed that prenatal alcohol exposure could cause synaptic loss with long-term effect and in a dose dependent manner. For instance, there were significant difference among the different treatment groups of P0, P14 and P30 as well (P < 0.05). Western blotting supported the results of immunofluorescent labeling. In conclusion, prenatal alcohol exposure can induce the synaptic loss dose dependently and with long-term effect. Our findings implicate that the synaptic loss with long-term effect in CNS probably contributes to the lifelong mental retardation and memorial lowliness associated with childhood FAS.

Objective To observe the effect of electroacupuncture and body-weight supported treadmill training in the treatment of spinal cord injury (SCI) after fractures of the thoracolumbar segment of the spine.Methods Forty-three patients with SCI after fractures of the thoracolumbar segment of the spine were randomly divided into a treatment group (22 cases) and a control group (21 cases). The patients in the treatment group were treated with electroacupuncture and body-weight supported treadmill training, while those in the control group were treated mainly with drugs. Patients were scored with the American Spinal Injury Association (ASIA) assessment and the modified Barthel index (MBI) initially and after 6 months. Results The ASIA and MBI scores of all patients were significantly higher after 6 months than before treatment, but those in the treatment group were significantly higher than those in the control group. Excellent and good ratings were applied to 77% of the treatment group, while only 48% of the control group, a statistically significant difference. Conclusions Electroacupuncture and body-weight supported treadmill training can effectively improve ability in the activities of daily living, sensation and locomotor abilities after thoracolumbar vertebral fractures.

Objective To evaluate the safety and efficacy of early carotid artery stenting in treating cerebral watershed infarction patients with carotid artery stenosis. Methods A total of 33 patients with acute cerebral watershed infarction complicated by carotid artery stenosis received carotid artery stenting within one week after the onset of the disease. The clinical safety and efficacy were evaluated. Results The carotid artery stenting was successfully accomplished in all 33 patients with a success rate of 100%. After the procedure, different degree of bradycardia and hypotension was seen in 23 patients, which restored to normal after prompt medication with atropine, dopamine, etc. During the procedure, one patients developed cerebral embolism due to dislodgment of emboli, resulting in contralateral hemiparalysis, and the contralateral limb muscle strength returned to preoperative status after proper treatment. After the treatment, no ipsilateral hemisphere excessive perfusion or cerebral hemorrhage occurred. Thirty days after the treatment, NHISS scores of the patients were obviously improved, which were significantly different from those determined before the treatment (P<0.05). Conclusion For the treatment of acute cerebral watershed infarction, early carotid artery stenting to relieve carotid artery stenosis is quite safe and it may improve the prognosis as well.
