ABSTRACT

Autoimmune retinopathy (AIR) is a group of immune-mediated retinopathies that usually results in severe loss of vision and visual field defects.AIR mainly includes paraneoplastic and non-paraneoplastic syndromes.One main feature of AIR is the presence of circulating anti-retinal antibodies (ARAs) in peripheral blood, which are produced through anti-tumor responses, anti-microbial responses, and immune responses induced by autoantigen fragments following retinal injury, and mainly attack retinal photoreceptor cells.ARAs are important for the diagnosis, progression assessment and treatment outcome of AIR.These ARAs often appear before the diagnosis of cancer and can be helpful for the early detection of malignant tumors.The mechanism of ARAs production, its pathological role in AIR, and its significance in clinical practice were reviewed in this article.

ABSTRACT

Objective To evaluate the clinical effects of vitrectomy with or without fovea-sparing internal limiting membrane peeling on macular foveoschisis (MF) secondary to pathologic myopia.Methods A non-randomized controlled study was adopted.Twenty-three patients (25 eyes) with refractive error ≥-8.00 DS and MF either combined with foveal retinal detachment or epi-macualr membrane or lamellar macular hole.The subjects were divided into non-internal limiting membrane peeling group (11 patients / 11 eyes) who underwent triamcinolone (TA) assisted vitrectomy and fovea-sparing internal limiting membrane peeling group (12 patients/14 eyes) who underwent TA assisted vitrectomy with fovea-sparing internal limiting membrane peeling.The baseline data such as age,best corrected visual acuity (BCVA),refractive error,axial length were not significant difference between the two group.Main outcomes were BCVA,remission of MF defined by optical coherence tomographyc OCT as well as complications.This study followed the Declaration of Helsinki and this protocol was approved by Ethic Committee of Xiamen Eye Center of Xiamen University (NO.XMYKZX-2016-YWS-007).Results All patients completed follow-up for more 6 months.BCVA (LogMAR) was 0.47±0.30 in non-internal limiting membrane peeling group and 0.40-±0.33 in fovea-sparing internal limiting membrane peeling group,showing no significant difference between the two groups (t =0.66,P=0.52).Complete remission of MF was achieved in 22 eyes.The remission time in non-internal limiting membrane peeling group was 2.5 (1.8,9.3) months,and 1.0 (1.0,3.8) months in fovea-sparing internal limiting membrane peeling group,no statistical significance was obtained between the two groups (U =35.00,P =0.09).One eye had post-operative macular hole in non-internal limiting membrane peeling group,accounting for 9%,while in fovea-sparing internal limiting membrane peeling group,one eye had macular hole,accounting for 7%,and one eye had rhegmatogenous retinal detachment post-operatively,accounting for 7%.Conclusions MF can be resolved by vitrectomy while complete remission can achieved more quickly when combined with fovea-sparing internal limiting membrane peeling.

ABSTRACT

Objective:To investigate the current status and related factors of psychological distress in tele-phone operators.Methods:Totally 575 telephone operators from sample of a convenient survey in a certain telecom-munication company of Shandong Province were selected.They were assessed with Kessler Psychological Distress Scale (K10),Connor-Davidson Resilience Scale (CD-RISC-10),Perceived Social Support Scale (PSSS)and Sim-plified Coping Style Questionnaire (SCSQ)for the evaluation of psychological distress,resilience,perceived social support and the coping style respectively.Ordinal logistic regression was used to identify the related factors of psy-chological distress.Results:The mean score of K10 was (24.7 ±6.7),91.8% (528 /575)of telephone operators had psychological distress.Specifically,24.5%(141 /575)had mild psychological distress,45.4% (261 /575)had moderate psychological distress,21.9% (126 /575)had severe psychological distress.Ordinal logistic regression a-nalysis indicated that the ones with good economic conditions (OR =1.74,95%CI:1.15 -2.63),higher level of re-silience (OR =1.13,95%CI:1.10 -1.17)and other social support (OR =1.07,95%CI:1.02 -1.12)had milder psychological distress;while with negative coping style (OR =0.29,95%CI:0.20 -0.41)had more severe psycho-logical distress.Conclusion:It suggested that the prevalence rate of psychological distress among telephone opera-tors is high.Poor economic conditions,lower level of resilience and social support,and negative coping style might be the related factors of psychological distress.

ABSTRACT

Objective To detect the single nucleotide polymorphisms (SNPs) in the upstream promoter region of chemokine like factor (CKLF) gene and analyze their possible associations with asthma and asthma-related phenotypes.Methods Direct Sequence of the 1553bp upstream promoter region of CKLF gene was performed in 245 Chinese Han human genomic DNAs (119 asthmatics and 126 controls).The frequencies of alleles, genotypes, and haplotypes were determined and the association of these SNPs with asthmawere further analyzed.Results Fournovel SNPs,SNP88 (T>C),SNPI96 (T>C),SNP568 (C> G) ,and SNP1047 (C > G) were found in the promoter region of CKLF.The frequency of rare allele was 0.168 (SNP88C), 0.168 (SNP196C), 0.352 (SNP568G) and 0.167 (SNP1047G), respectively.Haplotypes,their frequencies and the linkage disequilibrium coefficients between SNPs were constructed.Complete linkage disequilibrium (LDs) were observed between SNP88 and SNP196,SNP88 and SNP1047, as well as SNPI96 and SNP1047 ,respectively (D1 = 1.000,r2 = 1.000).SNP568 was in partial LD with the other three SNPs (r2 = 0.366).No association between asthma and the SNPs was observed.Conclusions Four SNPs in the regulatory region of CKLF in Chinese Han population were firstly identified.Although no significant correlation with asthma was revealed, the SNP and haplotype information is useful for other disease association studies in the future.
