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.

Objective To evaluate a new model of anterior spinal cord injury (SCI) syndrome and to explore the pathophysiology of SCI. Methods Fifty-five Wistar rats were randomly divided into a sham-operated group ( 10 rats) and an experimental group (45 rats). A metal hook was fixed in front of the rats'abdomens to compress the ventral part of the spinal cord in the experimental group. According to the degree and time of compression,the rats in the experimental group were divided into light, moderate, heavy injury subgroups. The tilt board test and the Bosso-Beattie- Bresnahan (BBB) locomotor rating scale were used to assess the rats' behavior at the 1st , 7th andl4th days and after 4 and 8 weeks. The latency of somatosensory evoked potential (SEP) and motor evoked potential (MEP) were measured before and 8 weeks after the operation. Results After the operation the gradients in the tilt board test and BBB scores in the experimental subgroups were all significantly lower than in the sham-operated group. There were also significant differences among the 3 severity subgroups. Eight weeks after the operation the average MEP latencies in the experimental subgroups were significantly longer than in the sham-operated group, and there were also significant differences among the 3 severity sub-groups. MEP in the heavy injury subgroup was significantly longer compared with the sham-operated group. Conclusions Obvious behavioral and neuroelectrophysiological changes were observed in the injured rats. Models of different severity could be prepared and reproduced to simulate clinical SCI.

Objective To evaluate skin barrier function in children with atopic dermatitis (AD) as well as healthy children from two communities in Shanghai and to assess the relationship between skin barrier function and AD severity.Methods Totally,169 children with AD and 142 healthy children aged 3-12 years were recruited from two communities (Changning Xining community and Jiading Juyuan community) in Shanghai,China.Transepidermal water loss (TEWL) and stratum corneum hydration were measured in normal appearing nonlesional skin at four body sites (dorsal and volar forearm,cheek and anterior shin) of the patients,as well as in normal skin at the same sites of the controls.AD severity was evaluated by using the severity scoring of atopic dermatitis (SCORAD) index.Results Compared with the healthy children,the patients with AD showed higher TEWL value at all of the four body sites (all P ＜ 0.05),but lower water content in stratum corneum at dorsal forearm and anterior shin (both P ＜ 0.05).In patients with AD,the SCORAD index was positively correlated with mean TEWL value,but negatively correlated with the mean water content in stratum corneum.Conclusion Skin barrier function may serve as an index for evaluating the severity of AD.

Objective To investigate the effectiveness and safety of carotid stenting for progressive cerebral watershed infarction (PCWI) patients with ipsilateral internal carotid stenosis or occlusion during the progressive stage. Methods The clinical data of 23 PCWI patients with ipsilateral internal carotid stenosis or occlusion treated with carotid stenting during the progressive stage were analyzed retrospectively. Among them, 18 were severe internal carotid artery stenosis, and 5 were carotid artery occlusion. Carotid artery stenting were performed in patients with severe internal carotid artery stenosis. The first-stage angioplasty and second-stage stenting were performed in patients with internal carotid artery occlusion. The National Institutes of Health Stroke Scale (NIHSS) score and the modified Rankin scale (mRS) were used to evaluate preoperative and postoperative neurologic deficits. Results Twenty-two of 23 patients were stented successfuly, the Thrombolysis In Myocardial Infarction (TIMI) flow grade was 3, and the technical success rate was 95. 7% . None of the patients demonstrated hyperperfusion in the ipsilateral hemisphere. At day 30 postprocedure, the NHISS scores were significantly improved compared with before procedure (4. 41 ± 1. 88 vs. 10. 00 ± 1. 47; t = 11. 234, P < 0. 001). The preprocedural TIMI flow grade was 3 in 12 patients (52. 2% ). Proportion of patients with TIMI flow grade 3 after procedure was significantly increased compared with before procedure (95. 7% vs. 52. 2% ; χ2 = 11. 274, P = 0. 002). The proportion of patients with mRS scores 0-2 at day 90 after procedure was significantly increased compared with before procedure (69. 6% vs. 0% ; χ2 = 24. 533, P < 0. 001). Conclusions Carotid stenting during the progressive stage is safe and it may improve the prognosis in PCWI patients with ipsilateral internal carotid stenosis or occlusion.

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.

BACKGROUND:Total knee replacement is regarded an effective treatment of knee osteoarthritis, based on the transformation of biology-psychology-social medicine pattern, the concept of“quality of life”has attracted increasing concerns.
OBJECTIVE:To observe the effects of total knee replacement surgery on the pain, function and quality of life among elder patients with severe knee osteoarthritis.
METHODA total of 102 elder patients with severe knee osteoarthritis were recruited from the Second Affiliated Hospital of Inner Mongolia Medical University between January 2010 and January 2013. The clinical manifestations and 12-month fol ow-up outcomes were observed and recorded. The involved patients were randomly divided into two grouptreatment group (59 cases, receiving total knee replacement) and control group (43 cases, receiving expectant treatment such as drugs, but no surgery). Patients were evaluated using HSS scale and WHOQOL-100 scale before surgery and 12 months after surgery. Furthermore, the correlation between influencing factors and HSS and WHOQOL-100 scores was analyzed.
RESULTS AND CONCLUSION:At 12 months postoperatively, the HSS scores of patients in treatment group was (82.03±10.17) points, which was obviously higher than that in control group (P<0.01). The WHOQOL-100 scores in treatment group were also significantly higher than that in control group (P<0.01). The psychology sub-item scores of patients after total knee replacement were close to that of normal controls (P>0.50). The regression analysis shows that marital status (β=1.988), complication (β=2.035) and HSS scores (β=2.108) are the main influencing factors for the quality of life among patients undergoing replacement. Experimental findings indicate that, HSS score is an effective indicator to assess the effect of total knee replacement on the pain and function of elder patients with severe knee osteoarthritis. WHOQOL-100 is introduced to further improve the assessment of quality of life after total knee replacement surgery in severe knee osteoarthritis. The marital status, complication and HSS scores are the key influencing factors for the quality of life among severe knee osteoarthritis patients. Deep vein thrombosis affects the out-of-bed time, and the mate-accompanying during the fol ow-ups plays a positive role on the quality of life and mental state of patients.
