ABSTRACT

Objective:To observe the morphological characteristics of internal carotid artery (ICA) siphon and ophthalmic artery (OA) in patients with non-arteritic anterior ischemic optic neuropathy (NAION) based on CT angiography (CTA) three-dimensional reconstruction of ICA siphon and OA models.Methods:A retrospective cohort study. From January 2017 to January 2019, 26 patients with 31 eyes (NAION group) who were diagnosed with NAION by ophthalmic examination at Beijing Friendship Hospital, Capital Medical Universitywere included in the study. Among them, there were 11 males with 13 eyes, and 15 females with 18 eyes; the age was 67.52±6.30 years old. Nineteen eyes of 19 non-affected contralateral eyes were selected as the contralateral eye group. Among them, there were 9 males with 9 eyes and 10 females with 10 eyes; the age was 65.95±5.66 years old. Twenty-six eyes of 26 age- and sex-matched subjects with normal fundus examination during the same period were selected as the normal control group. All subjects underwent best corrected visual acuity (BCVA), intraocular pressure, fundus photography and CTA examination. The data obtained from CT scans were reconstructed by 3D model, and the anatomical morphology of ICA siphon was divided into U-shape, V-shape, C-shape and S-shape; the diameter of ICA siphon portion and the diameter at the beginning of OA were measured. One-way analysis of variance was used to compare the diameter of the OA at the beginning of the OA and the diameter of the ICA siphon between the three groups of eyes.Results:The diameters at the beginning of OA in the NAION group, the contralateral eye group, and the normal control group were 1.17±0.20, 1.34±0.17, and 1.39±0.15 mm, respectively, and the differences among the three groups were statistically significant ( F=12.325, P<0.05); there was no significant difference between the contralateral eye group and the normal control group ( P=0.310). In the NAION group, the anatomical morphology of the ICA siphon was U-shaped and V-shaped in 20 (64.52%) and 8 (25.81%) eyes respectively, and S and C-shaped in 3 eyes (9.67%); in the contralateral eye group, in the control group, the ICA siphon shape of the eyes examined was U-shaped and V-shaped, and S-shaped and C-shaped were rare. The diameters of the ICA siphons in the NAION group, the contralateral eye group, and the normal control group were 3.50±0.69, 3.22±0.59, and 3.55±0.54 mm, respectively. There was no significant difference between the three groups ( F=1.860, P=0.163). Conclusion:U-shaped and V-shaped ICA siphons are more common in NAION-affected eyes; the diameter of the starting point of OA is significantly reduced.

ABSTRACT

Objective:To evaluate the inhibitory effect of a retinoid derivative ECPIRM on proliferation of a cutaneous T-cell lymphoma (CTCL) cell line HH, and to explore its potential mechanisms.Methods:Cultured HH cells were treated with ECPIRM at different concentrations of 0 (control group) , 5, 10 and 20 μmol/L separately for 72 hours, cell counting kit-8 (CCK8) assay was performed to evaluate the effect of ECPIRM on the proliferative activity of HH cells, and flow cytometry to investigate the effect of ECPIRM on apoptosis of HH cells. Some HH cells were treated with 10 μmol/L ECPIRM for 72 hours, transcriptome sequencing was performed to investigate gene expression changes triggered by ECPIRM in HH cells, and Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis and gene ontology (GO) enrichment analysis were then performed to analyze differentially expressed genes in HH cells induced by ECPIRM. Reverse transcription-qPCR was subsequently conducted to verify changes in key gene expression in related pathways. Intergroup differences were analyzed by using one-way analysis of variance, and least significant difference (LSD) - t test was used for multiple comparisons. Results:CCK8 assay showed that the 50% inhibitory concentration (IC50) of ECPIRM on HH cells was 4.91 ± 2.48 μmol/L, the viability of HH cells significantly differed among the control group, and 5-, 10-and 20-μmol/L ECPIRM groups (100.00% ± 2.87%, 49.58% ± 4.53%, 48.36% ± 2.88%, 31.44% ± 2.46%, respectively, F=162.86, P < 0.001) , and was significantly lower in the 5-, 10-and 20-μmol/L ECPIRM groups than in the control group ( t=15.36, 15.73, 20.89, respectively, all P < 0.001) . Flow cytometry showed that there was a significant difference in the apoptosis rate among the 4 groups (11.51% ± 1.84%, 23.83% ± 5.72%, 36.19% ± 8.33%, 49.75% ± 4.10%, respectively, F=17.62, P < 0.001) , and the 10-and 20-μmol/L groups showed significantly increased apoptosis rates compared with the control group ( t=4.46, 6.92 respectively, both P < 0.01) . Transcriptomics analysis revealed that the inhibitory effect of ECPIRM on the cellular proliferative activity may be related to the metabolic regulation of steroids. As reverse transcription-qPCR revealed, the 10-μmol/L ECPIRM group showed significantly decreased mRNA expression of L-amino acid oxidase (IL4I1) , acetyl-coenzyme A acetyltransferase 2 (ACAT2) , 3-hydroxy-3-methylglutaryl-coenzyme A synthase 1 (HMGCS1) , mevalonate diphosphate decarboxylase (MVD) , 3-β-hydroxysteroid-8,7-isomerase (EBP) , very low-density lipoprotein receptor (VLDLR) , 3-hydroxy 3-methylglutaryl-CoA reductase (HMGCR) compared with the control group (all P < 0.05) . Conclusion:The retinoid derivative ECPIRM exerted marked anti-proliferative and apoptosis-inducing effects on HH cells, which may be related to the decreased expression of key genes involved in steroid metabolism.

ABSTRACT

Objective To observe the choroidal vascularity index (CVI) and the subfoveal choroidal thickness (SFCT) of central serous chorioretinopathy (CSC),and to compare the stability and consistency of the two methods of measurement.Methods A retrospective study.Thirty-one patients with unilateral acute CSC who visited the Department of Ophthalmology of Beijing Friendship Hospital for the first time during the period from Nov 1st,2016 to Mar 18th,2018 were included in the study.Thirty-one healthy age-matched subjects were enrolled as controls.All CSC affected eyes and their fellow eyes and healthy eyes were scanned by single-line enhanced depth imaging of OCT through central fovea of macula to measure their SFCT.The image was binarized and then the CVI of a 1500 μm range below fovea was calculated,i.e.the ratio of vascular (or lumen) area to total choroidal area.CVI and SFCT were compared among CSC eyes,fellow eyes and healthy eyes by variance analysis.Intra-group correlation coefficient (ICC),Bland-Altman curve and coefficient of variation (CV) were used to analyze the repeatability,consistency and stability of CVI and SFCT;and Medcalc18.2.1 software was used to draw the Bland-Altman curve and observe the consistency of the two measurement methods.Results There were statistically significant differences in CVI and SFCT between CSC affected eyes and fellow eyes (t=3.470,2.844;P=0.001,0.006),CSC affected eyes and healthy eyes (t=6.977,6.277;P<0.001,<0.001),fellow eyes and healthy eyes (t=3.508,3.433;P=0.001,0.001).Relative consistency analysis of CVI and SFCT showed that the ICC of single measurement and average measurement of CVI were 0.967 and 0.983 respectively,and that of single measurement and average measurement of SFCT were 0.937 and 0.967 respectively.The consistency of CVI and of SFCT was very good.The ICC value of CVI was slightly higher than that of SFCT.The results of repeatability analysis of CVI and SFCT showed that the difference between the two CVI measurements was smaller,and the difference between the two SFCT measurements was larger.And CVI and SFCT stability analysis results showed that the CV of CVI and SFCT were 10.5% and 25.3% respectively.CVI has smaller CV than SFCT.Conclusions Compared with healthy eyes,CVI and SFCT are increased in CSC affected eyes and fellow eyes.And compared with SFCT,CVI has better consistency,repeatability and stability.

ABSTRACT

Objective To observe the choroidal blood flow and morphological changes in patients with severe stenosis of internal carotid artery stenosis (ICAS).Methods A retrospective case-control study. Forty-six patients (46 eyes) with ICAS were enrolled in this study. There was severe stenosis in one side (the eyes in this side were set as case group) and mild or no stenosis in other side (the eyes in this side were set as control group). Color doppler ultrasound (CDI) was used to observe the changes of hemodynamic parameters of the ophthalmic artery (OA) and posterior ciliary artery (PCA),the main parameters of ultrasound Doppler imaging are peak systolic velocity (PSV), end diastolic velocity (EDV), resistance indices (RI) and the calculation of the pulsation indices (PI) through the use of a formula. Enhanced binarization of deep imaging coherence tomography (EDI-OCT) was used to measure the subfoveal choroidal thickness (SFCT). The total subfoveal choroidal area (TCA), luminal (LA), stromal (SA) and choroidal vascularity index (CVI) were obtained by modified image binarization technique.Results In the case group, the PSV in the OA and PCA was significantly lower than that of the control group (t=?2.200, ?2.612;P=0.030, 0.011). There were no significant differences in EDV, RI, PI of OA (t=0.337, ?1.810, ?1.848;P=0.737, 0.074, 0.068) and PCA (t=?1.160, 1.400, 0.815;P=0.249, 0.165, 0.417). The SFCT (t=?3.711,P<0.001), TCA (t=?2.736,P=0.007), LA (t=?3.188, P=0.002) and CVI (t=?2.096,P=0.039) of the case group was significantly lower than that of the control group. There were no significant differences in SA (t=?1.262,P=0.210) and LA/SA (t=?1.696,P=0.093).Conclusion In severe stenosis ICAS eyes, the PSV in the PCA and SFCT, TCA, LA, CVI are decreased.

ABSTRACT

Objective To study the early renal function assessment value of urine kidney injury molecule-1(KIM-1)level in patients with unilateral obstruction renal diseases.Methods Seventy-eight patients with unilateral obstruction renal diseases were selected,and the glomerular filtration rate(GFR) was detected by 99Tcm-diethylene triaminepentaacetic acid (DTPA) renal dynamic imaging method. The patients were divided into 4 groups according to the GFR: normal renal function group with GFR>40 ml/(min·1.73 m2)25 cases(A group),low-injury renal function group with 20 ml/(min·1.73 m2)<GFR≤40 ml/(min·1.73 m2) 22 cases (B group), mid-injury renal function group with 10 ml/(min·1.73 m2) <GFR ≤ 20 ml/(min·1.73 m2) 16 cases (C group), serious-injury renal function group with GFR ≤ 10 ml/(min·1.73 m2) 15 cases (D group). Twenty-five healthy people were selected as control group (E group). The urine KIM-1 and serum creatinine and blood urea nitrogen levels were detected. The correlation among urine KIM-1, serum creatinine and blood urea nitrogen was analyzed. Results The urine KIM-1 in A group, B group, C group and D group was significantly higher than that in E group:(49.70 ± 9.23),(57.84 ± 10.06),(67.71 ± 7.36)and(65.84 ± 22.48)ng/L vs.(39.17 ± 3.28)ng/L,in A group and B group was significantly higher than that in C group and D group,in A group was significantly higher than that in B group, and there were statistical differences (P<0.05). There was no statistical difference in urine KIM-1 between C group and D group(P>0.05).There was no statistical difference in serum creatinine and blood urea nitrogen among 5 groups (P>0.05). The KIM-1 was negatively correlated with GFR(r=-0.441,P<0.01),and the serum creatinine and blood urea nitrogen were not correlated with GFR (r = -0.115 and 0.019, P>0.05). The receiver operating characteristic curve analysis result showed that the area under curve of urine KIM-1 in the diagnosis of kidney injury was significantly higher than that in serum creatinine and blood urea nitrogen(0.804 vs.0.441 and 0.567);the sensitivity and specificity were 82.6% and 66.7%,56.5% and 53.3%,66.9% and 66.7%.Conclusions The expression level of urine KIM-1 of unilateral obstructive nephropathy with different degree of kidney injury is a higher sensitivity marker compared with serum creatinine and blood urea nitrogen, which is helpful for diagnosing kidney injury early in clinic.

ABSTRACT

Objective To analyze the relationship between internal carotid artery (ICA) stenosis and ipsilateral retinal vascular calibers,and to investigate the feasibility and accuracy of changes of retinal vascular calibers for assessment of ICA stenosis.Methods Unilateral ICA and ipsilateral retinal vascular of 243 patients were enrolled based on CTA and fundus imaging.Patients were divided into 4 groups according to the highest ICA stenosis rate (Rmax),i.e.no stenosis group,mild stenosis group,moderate stenosis group and severe stenosis group.The differences of retinal vascular calibers among four groups and correlation between retinal vascular calibers and ICA stenosis were analyzed.Results The average central retinal vein equivalents (CRVE) in moderate ICA stenosis group and severe stenosis group were significantly wider than those in the other two groups (all P<0.05).There was no statistical significance of central retinal artery equivalent (CRAE) nor retinal arteriolar-to-venular ratio (AVR) among groups (both P>0.05).Rmax was positively correlated with CRVE (r=0.27,P<0.01) and negatively correlated with AVR (r=-0.16,P<0.05),whereas Rmax had no correlation with CRAE (P>0.05).CRVE was the impact factor of ipsilateral Rmax (B=0.243,P<0.01),but the adjusted R2 of the model was weak (0.173).Area under the ROC curve of CRVE was 0.619 in assessing ICA moderate and severe stenosis,and taking threshold as 229.5μm,the sensitivity and specificity was 80.3% and 40.1%,respectively.Conclusion CRVE can assess and predict ICA stenosis to some extent,but the diagnosis efficacy is limited.

ABSTRACT

Objective To observe the correlation of serum aquaporin 4 (AQP4) antibodies and condition and visual prognosis in patients with severe neuromyelitis optica spectral disorders (NMOSD). Methods Fifty NMOSD patients with visual acuity of 20/200 or worse in at least one eye were enrolled in this retrospective analysis. There were 12 males and 38 females. The age ranged from 17 to 65 years, with the mean of (39.86±2.02) years. The patients were divided into two groups according to the serum AQP4-IgG status. The ophthalmologic examination, serum anti-nuclear antibodies (ANA), myelin oligodendrocyte glycoprotein (MOG) antibody detection and vision prognosis were compared and analyzed. Glucocorticoid therapy was delivered to 46 patients who were within 1 month of onset. The visual acuity of the patients after treatment was divided into complete recovery, partial recovery, stabilization and reduction, and the visual acuity of the two groups were analyzed. Results Among 50 patients, there were 30 (60%) seropositive patients (positive group), 20 (40%) seronegative patients (negative group). The positive group had significantly higher ratio of female to male (P=0.004), and more binocular optic neuritis (ON) (P=0.010) compared with the negative group. More recurrence ON were also found in the positive group, but without statistic difference between two groups (P=0.167). There was no difference of age, course, and vision damage degrees and abnormal orbital MRI scanning between two groups (P>0.05). Among 24 patients who underwent serum ANA detection in the positive group, 8 patients were positive. All of 18 patients who underwent serum ANA detection in the negative group were negative. The difference of the ratio of serum ANA positive patients between two groups was significant (P=0.030). Serum MOG antibody detection in the positive group was negative (0/10). Sixteen patients who underwent MOG antibody detection in negative group, 4 patients were positive. After treatment, there were 23.3%, 23.3%, 53.3% patients with vision of complete recovery, partial recovery and reduction in the positive group; 25.0%, 30.0%, 25.0% patients with vision of complete recovery, partial recovery and reduction in the negative group, respectively. There was no difference in proportion of vision with complete recovery and partial recovery between two groups (P=0.163, 0.607), but significant difference was observed in proportion of vision with stabilization and reduction between two groups (P=0.021, 0.048). Conclusions The positive serum AQP4 antibody is common in patients with severe NMOSD. The patients with AQP4 antibody in the serum are more likely combined with immunological serological markers and poor vision prognosis.

ABSTRACT

OBJECTIVE:To investigate the effect of polyamide on the separation on phenolic acids components by nanofiltra-tion process. METHODS:Phenolic acids components were selected as targets,extracted from the Salvia miltiorrhiza,Lonicera ja-ponica or intermediate preparations (tea polyphenols) with water,and filtered with membranes with different pore sizes. The con-tent changes of components were analyzed by HPLC. RESULTS:Danshensu,protocatechuic aldehyde and caffeic acid could better transmit nanofiltration membranes with 3 different pore sizes;with the decrease of pore size,the rejection rates of neochlorogenic acid,chlorogenic acid,rosmarinci acid,ECG and EGCG grew in different levels. But salvianolic acid B was almost retained by the membrane with low molecular weight except 600-800 Da. CONCLUSIONS:Molecular weight importantly influenced nanofiltra-tion separation on phenolic acid components;nanofiltration has a good prospect in enrichment of phenolic acids components.

ABSTRACT

Background The diseases of neuro-ophthalmology are common,which can influence the quality of patients' life seriously.The 39-item National Eye Institute Visual Function Questionnaire (NEI VFQ-39) is an instrument to assess self-reported visual impairment in studies of vision.However,until now,no studies have been performed to specifically assess the vision-related quality of life in persons with diseases of neuro-ophthalmology.Objective To evaluate vision-related quality of life for neuro-ophthalmology inpatients through the NEI VFQ-39,for the better treatment and nursing for them.Methods Ninety-seven neuro-ophthalmology inpatients were scheduled in research from June 1 to September 30,2012,and we collected all the clinical datas and the Chinese version NEI VFQ-39.The NEI VFQ-39 subscale item scores were compared among subgroups divided by monocular or binocular incidence,diseases and best corrected visual acuity(BCVA),and correlation analysis of the NEI VFQ-39 scores and BCVA for better-seeing and worse-seeing eyes was performed.Results The mean age of scheduled patients was (36.6±14.4)years,with no difference in gender.The mean composite score of VFQ-39 was 57.36(46.50,73.38),mental health subscale score was lowest [45.00 (35.00,60.00)].In the four eye diseases groups,except for eye pains,degree of dependence,periphery vision,anterior ischemic optic neuropathy (AION) group had lower scores compared with the other three groups,but there were no statistical significances among the four groups (all at P>0.05).Except for eye pains,patients with monocular incidence had better scores than those with binocular incidence,with statistical significant significances between them(all at P<0.05).Patients with BCVA in the better-seeing eye > 20/32 had better scores than the other two groups,compared with the BCVA in the better-seeing eye <20/200 group,except for overall health and eye pains,cornpared with the 20/200 ≤ BCVA in the better-seeing eye <20/23 group,except for eye pains,social activity and color vision,and the rest subscale scores had significant differences among the three groups(all at P<0.05).NEI VFQ-39 scores had positive correlations with the BCVA for better-seeing and worse-seeing eyes,and had strong correlations with the BCVA for better-seeing.Conclusions Neuro-ophthalmology diseases have serious influences on patients' visual function and quality of life.The quality of life has direct correlation with BCVA,so improving their visual function is helpful to their quality of life.

ABSTRACT

<p><b>BACKGROUND</b>Optic neuritis (ON) is often the first symptom of multiple sclerosis (MS) and neuromyelitis optica (NMO) while there has been very little research reported on ON combined with Sjögren's syndrome (SS). The aim of this study is to provide different treatments and services for and NMO patients combined with SS.</p><p><b>METHODS</b>Twenty-seven patients with ON combined SS were divided into two groups: corticosteroid group (C group, methylprednisolone sodium succinate, 14 patients) and corticosteroid+ immunosuppressant group (C+I group, leflunomide, 13 patients). ON relapse times in 1 year after treatment, number of patients who relapsed to NMO/MS in 1 years, visual acuity and retina nerve fiber layer (RNFL) thickness were measured. Mann Whitney-Wilcoxon test was used to compare continuous variables and Chi-square test or Fisher's exact test was to compare proportions.</p><p><b>RESULTS</b>ON combined with SS patients had higher incidence rates in middle-aged women who have binocular damage and heavier visual function damage or when there is an easy relapse, and the patients are often hormone dependent. The patients are more likely anti-aquaporin-4 IgG seropositive (70.4%). They are liable to form a centrocecal scotoma and tubular vision. The times of relapse decreased in patients who used immunosuppressant, and a significant difference was found between immunosuppressant and non-immunosuppressant groups in visual acuity recovery during 6-month follow-up period (P < 0.05); however, the RNFL thickness at the four quadrants was not significantly different.</p><p><b>CONCLUSIONS</b>The effect of immunosuppressant plus corticosteroid on the early onset of ON combined with SS was to provide ON remedy and to prevent recurrence in clinics. This study provides a significant reference for the prevention and treatment of ON on the basis of immunosuppressant and corticosteroid.</p>

ABSTRACT

Objective To study the process of removing bacterial endotoxins by ultrafiltration technology in dextran 40 injection. Methods Dextran 40 solution was ultrafiltrated by 100,200,and 300 kDa aperture ultrafiltration membranes with composite, PES and PVDF materials. In order to optimize ultrafiltration process,the content of effective component and endotoxins were detected by HPLC and kinetic-turbidimetry,respectively,and the change of particle size distribution in dextran 40 solution was analyzed before and after ultrafiltration. Results The transmittance of dextran 40 was close to the same MWCO and different membrane material. When MWCO reached 300 kDa,the transmittance was above 91%,which met the requirement of filtration. The endotoxin removal rates by 100-300 kDa composite ultrafiltration membranes were more than 99%. But the endotoxin removal rates of both of PES and PVDF membranes were less than 40%,which were unable to guarantee the removal efficiency of the endotoxin in dextran 40 solution. The particle size declined after ultrafiltration by 300 kDa composite membrane, and level of the insoluble particles decreased. Conclusion The 300 kDa composite ultrafiltration membrane can effectively remove endotoxin in dextran 40 solution with less main components loss. The material can meet requirements for producing dextran 40 injection.
