Background In previous study,peripheral retinal nerve fiber layer (RNFL) thickness is considered to be the earliest structural changes which can be detected.3D-OCT can measure the thickness of macular ganglion cell complex (mGCC),which makes the detection of primary glaucoma possible in the early stage.Objective This study was to measure the thickness of mGCC and disc-peripheral RNFL in early stage of primary glaucomous eyes by 3D-OCT and assess the anatomic basis of glaucoma-induced optical nerve damage.Methods 3D-OCT images from 10 patients with advanced stage primary glaucoma in one lateral eye and early stage glaucoma in fellow eye from December 2010 to December 2012 were prospectively analyzed in China-Japan Friendship Hospital.The patients were diagnosed based on the recommended standard of National glaucoma group (1987 version) and received routine eye examination.3D-OCT scanning was performed using 3D-macular mode,3D-macular Wide mode and 3D-disc mode with TOPCON 3D-OCT 2000 system,and the images at macular 6 mm×6 mm area were analyzed.The posterior pole area was divided into 5 concentric rings from fovea toward periphery and equally subdivided into 100 small checks,with the area of 0.6 mm×0.6 mm for each.The probable values in each check were calculated as the ratio of each figure and corresponding normal value.The probable values were expressed as red color (P＜ 1％),yellow color (P＜5％) and gray color (P≥ 5％).Then the disc-periphery RNFL thickness and disc cup were evaluated.Results No evident abnormality was found in the thicknesses of photoreceptors layer and bipolar cell layer in both advanced glaucomous eyes and the early stage of glaucomous eyes in the 10 patients.Serious damage of visual field was seen in the advanced glaucomous eyes and presented with red color in the parapapillary RNFL area,mGCC area and macular RNFL area,showing an evidently attenuation of the thicknesses of parapapillary RNFL,mGCC and RNFL.However,the visual field was close normal in the early stage glaucomous eyes,and mGCC and macular RNFL showed yellow color,while green or yellow color was exhibited in the parapapillary RNFL area,indicating mGCC and macular RNFL thickness was reduced,but parapapillar RNFL thickness was near normal.Conclusions The change of mGCC thickness is earlier than that of peripheral RNFL at optic disc in primary glaucomaous eyes,which may imply that the disappear of macular ganglion cell body is earlier than that of the axon.

Objective To explore the influence of the fetal microchemirism in the thyroid tissue on the Graves' disease(GD) animal model.Methods Mice in experimental group were injected with Ad-TSH289(5?108IU) to construct the GD animal model,and when the immunization was over,the experimental group was randomly divided into three parts again: two groups were mated with male mice until two weeks of pregnancy or two weeks post-partum while the other group was simple immunized with Ad-TSH289 only.SRY was tested by real-time PCR.Thyroid tissue was stained with HE for pathological examination.Results Histological examination of the thyroid gland revealed that 61.8% of simple immunized mice had goiter,the success rate of GD animal model was 38.5% in pregnancy group,but 76.9% in postpartum groups(P

Objective To determine the utility of musculoskeletal ultrasound imaging to support physical findings in different stages of recovery and in recommending treatment regimens.Methods Forty-three hemiplegic stroke survivors with shoulder pain were enrolled.Physical examinations were performed 3 and 6 months after the stroke using a visual analogue scale (VAS),a modified Ashworth scale,measurements of passive range of motion and Brunnstrom staging.This was coupled with sonography of the long head of the biceps,the subscapularis tendon,the supraspinatus tendon,the infraspinatus tendon,the acromioclavicular joint and the subacromial-subdeltoid bursa.Results Three months after the stroke the average VAS score correlated negatively with the average Brunnstrom stage of the shoulders (r=-0.39,P≤0.01),with the range of passive abduction (r=-0.56,P≤ 0.01),the range of passive external rotation (r=-0.36,P≤ 0.02),and the range of passive flexion (r=-0.37,P≤ 0.02).It was positively correlated with abnormal sonographic findings of the long head tendon of the biceps (r=0.32,P≤ 0.04),the subscapularis tendons (r=0.31,P≤0.04) and the supraspinatus tendons (r=0.53,P≤0.01).However,3 months later the VAS results were negatively correlated with Brunnstrom stage (r=-0.45,P ≤ 0.01),range of passive shoulder abduction (r=-0.60,P≤0.01),range of passive external rotation (r=-0.41,P≤0.01),and passive range of flexion (r=-0.52,P≤ 0.01),but positively correlated with spasticity (r=0.34,P≤ 0.03),biceps tendinopathy (r=0.45,P≤0.01),subscapularis tendinopathy (r=0.33,P≤ 0.03) and supraspinatus tendinopathy (r=0.56,P≤ 0.01).Rotator cuff injury was significantly more severe 6 months after stroke than at 3 months.The incidence of pain in the hemiplegic shoulder and abnormal sonographic findings of the biceps tendon and subscapularis tendon were significantly higher at 6 months than at 3 months after the stroke.Supraspinatus tendon problems were notable both at 3 and 6 months.Conclusions Pain in a hemiplegic shoulder is positively correlated with abnormal sonographic findings but negatively correlated with Brunnstrom stages and passive range of motion 3 and 6 months after stroke.Six months after stroke,pain is positively correlated with muscle tone.The tendon at the long head of the biceps and the rotator cuff are vulnerable to injury,especially at 6 months after stroke.

Objective:To explore the changes in the diffusion tensor imaging (DTI) parameters of the pontocerebellar tract 3 months and one year after ischemic stroke and analyze the data′s potential for predicting long-term motor outcomes.Methods:Thirty patients with middle cerebral artery infarction were prospectively studied using DTI within 3 months and 1 year after the onset. A region of interest-based analysis was performed for the fractional anisotropy (FA) of the middle cerebellar peduncles (MCP) in the pontocerebellar fibers (PCF). Neurological functioning was evaluated using the National Institutes of Health Stroke Scale and the degree of paresis was assessed at the same time using paresis grading. At one year after the onset, balance function, functional prognosis and self-care ability were evaluated using the Brunel Balance Scale, the modified Rankine Scale and the Functional Independence Scale respectively.Results:The average FA on the healthy side 3 months and 1 year after onset was significantly less than on the affected side at each time point. The ratio of the FA of the affected side to that of the unaffected side (rFA) in the PCF correlated significantly with the average paresis scores of the lower and upper extremity and the total paresis score at each time point. Moreover, the rFA of the PCF was significantly correlated with the average functional independence score, the prognosis for the upper and lower extremities as well as motor functioning. The area ratio under the ROC curve of the PCF for predicting lower extremity motor outcome was 0.84, and the optimal threshold was 0.92 (sensitivity 71.4%, specificity 73.9%). The area ratio under the ROC curve was not a significant predictor of upper extremity motor outcome.Conclusion:The DTI parameter rFA of the PCF in patients with subacute middle cerebral artery infarction can help to predict the long-term recovery of motor ability. It can serve as an important reference index for predicting the long-term motor ability of the lower limbs.

Objective:To compare the application of three different glomerular filtration rate(eGFR)-estimating equations in the elderly aged 60 years and over.Methods:The patients aged ≥ 60 years in our hospital from January 2012 to October 2017 were included as research subjects who underwent three GFR detection(as measured GFR i. e.mGFR)of serum creatinine(Scr), serum cystatin C(sCysC)and GFR by 99mTc-DTPA renal dynamic imaging.The advantages and disadvantages of each GFR-estimating(eGFR)equation in the elderly patients were compared.Results:A total of 122 patients were enrolled, including 90 males(73.8%), with a median age of 77 years.The median Scr and sCysC were 109 μmol/L and 1.39 mg/L, respectively, with their average of mGFR being(45.70±18.91)ml·min -1·1.73m -2.Overall, each eGFR-Scr equation over-estimated the GFR in varying degrees.In eGFR-Scr, full age spectrum equation(FAS)-Scr had the smallest bias(2.34)and the best accuracy(P30 75.4%), followed by Berlin Initiative Study(BIS)-Scr(P30 71.3%). In eGFR-CysC, the P30 of FAS-CysC and chronic kidney disease(CKD)-Epidemiology Collaboration(EPI)-CysC were 75.4% and 71.3%, respectively, and the accuracy of eGFR-CysC was comparable to that of BIS-Scr and FAS-Scr.In eGFR-combi, the bias of FAS-combi was the smallest(1.10), and the accuracy of FAS-combi, BIS-combi and CKD-EPI-combi was comparable, the P30 was 81.1%, 79.5% and 74.6%, respectively, and the P30 of FAS-combi and BIS-combi was higher than that of eGFR-Scr and eGFR-CysC.In the 60-80 age group, the accuracy of FAS-combi and BIS-combi was the best, P30 was 77.8% and 76.4% respectively, while, the accuracy of other equations were poor.In patients ≥ 80 years old, except for the modification of diet in renal disease(MDRD)equations and CKD-EPI-scr equation, the accuracy of other equations was acceptable, among which the accuracy of eGFR-combi equation was the best, and the P30 of FAS-combi, BIS-combi and CKD-EPI-combi were 86.0%, 84.0% and 80.0%, respectively. Conclusions:In elderly patients aged 60 years and over, the application of eGFR-combi equation is better than that of the respective eGFR-Scr and eGFR-CysC equations.The FAS equation has the best bias and accuracy, followed by the BIS equation.

【Objective】 To explore B lymphocytes’ role and mechanisms in angiotensinⅡ/phenylephrine (AngⅡ/PE) induced cardiomyopathy so as to understand the role of inflammatory cells in myocardial injury. 【Methods】 AngⅡ/PE was administered to wild-type (WT) and B cells deficiency (μMT) mice for 14 days or 28 days. The mice were analyzed by blood pressure measurement, echocardiography imaging, flow cytometry, and histology. Cardiac fibrosis was evaluated by Masson staining. 【Results】 Compared with the control group, the left ventricular mass (P<0.01), heart mass/tibia length ratio (P<0.01) and cross-sectional area of cardiomyocytes in AngⅡ/PE group were significantly increased (P<0.01). After 2 weeks of AngⅡ/PE treatment, B lymphocytes (P<0.05), CD45⁺ leukocytes (P<0.05), CD64^-Ly6C⁺ monocytes (P<0.05), CD64⁺Ly6C^-macrophages (P<0.05) and Ly6g⁺ neutrophils (P<0.05) were recruited in myocardial tissue. Compared with WT_AngⅡ/PE group, the heart weight/tibia length ratio (P<0.05), left ventricular weight (P<0.05) and myocardial cell cross-sectional area (P<0.05) of μMT_AngⅡ/PE mice were significantly improved. CD45⁺Ly6C⁺CD64^- monocytes (P<0.05) and CD45⁺Ly6C^-CD64⁺ macrophages (P<0.05) were significantly decreased. 【Conclusion】 B lymphocytes deficiency improves AngⅡ/PE induced cardiac hypertrophy by reducing the infiltration of CD45⁺Ly6C⁺CD64^- monocytes and CD45⁺Ly6C^- CD64⁺ macrophages.

Objective: To determine the subcortical areas associated with post-stroke dysphagia and its recovery using diffusion tensor images. Methods: Ten patients with middle cerebral artery lesions and dysphagia were selected into the dysphagia group, while another 10 counterparts without dysphagia were chosen for the non-dysphagia group. The ratios of diffuse anisotropy (rFAs) in eleven regions of interest (ROIs) on both the healthy and affected sides were recorded and compared between the two groups. One and 3 months later, the rFA values of the dysphagia group were again measured and the rFAs were related with dysphagia outcomes and severity using Spearman correlation analysis. Results: Comparing the rFAs of the 11 ROIs between the two groups revealed significant differences between the insulae of the dysphagia group and the non-dysphagia group. Three months later the rFA values of the insulae, cerebral peduncles and superior cerebellar peduncles had increased significantly in the dysphagia group. The average dysphagia outcome and severity score of the dysphagia group was significantly lower one month after the treatment than 3 months later. Moreover, the outcome and severity score was found to be significantly correlated with the rFA values of the insulae and of the superior cerebellar peduncles one month after the treatment, but with that of the cerebral peduncles only after 3 months. Conclusion Dysphagia within one month of the onset of infarction is related to the insulae, the cerebral peduncles and the superior cerebellar peduncles. After 3 months it is associated with the cerebral peduncles.
