Methods: Thirty-three patients with ophthalmopathy of Graves’ disease, fifty-six Graves’ patients without ophthalmopathy and sixty normal subjects as control were involved in the present case-control study. The polymorphisms were evaluated by polymerase chain reaction fragment length polymorphism (PCR-RFLP). Com-parisons were made of gene frequencies and allele frequencies between the groups. Results: The gene frequencies of CT and allele frequencies of T were much higher in Graves’ patients with ophthalmopathy than that in the group without ophthalmopathy (P=0.020, P=0.019). The gene frequencies of GG and allele frequencies of G in patients with Graves’ disease were significantly increased as compared with control group (P=0.008, P=0.007). The data suggest that smokers with Graves’ disease seemed to be more predisposed to ophthalmopathy than non-smokers (P=0.018). Conclusion: Our results suggest that an allele of T at position –318 of promoter is associated with genetic susceptibility to Graves’ ophthalmopathy while an allele of G at position 49 of exon 1 is associated with genetic susceptibility to Graves’ disease instead. Smoking is believed to be a major risk factor for ophthalmo-pathy.展开更多

Patients were divided into 4 groups as medial-inferior, mediallateral（balanced）, medial-lateral-inferior, and lateral only according to the applied surgical technique. Surgical indications, regression degrees on Hertel exophthalmometer, new-onset diplopia in the primary gaze and new-onset gaze-evoked diplopia after surgery and visual acuity in cases with dysthyroid optic neuropathy（DON） were compared between different surgical techniques.RESULTS： The study included 248 eyes of 149 patients. The mean age for surgery was 42.3±13.2 y. DON was the surgical indication in 36.6% of cases, and three-wall decompression was the most preferred technique in these cases. All types of surgery significantly decrease the Hertel values（P〈0.005）. Balanced medial-lateral, and only lateral wall decompression caused the lowest rate of postoperative new-onset diplopia in primary gaze. The improvement of visual acuity in patients with DON did not significantly differ between the groups（P=0.181）. CONCLUSION： The study show that orbital decompression surgery has safe and effective long term results for functional and cosmetic rehabilitation of GO. It significantly reduces Hertel measurements in disfiguring proptosis and improves visual functions especially in DON cases.展开更多

Approved by the local institutional review board（IRB）, 106 consecutive patients with GO were included in this prospective study. All subjects were divided into two groups according to the patients＇ clinical activity score（CAS）： the CAS positive group（CAS ≥3） or the CAS negative group（CAS 〈3）. T2 relaxation time of extraocular muscles（T2RT; ms） and the areas of four extra-ocular muscles（AEOMs; mm2） were measured by 3D T2-mapping MR sequence before and after methylprednisolone treatment, so as the CAS and some ophthalmic examinations including visual acuity, intra-ocular pressure, eyeball movement, diplopia and proptosis. In addition, 24 healthy volunteers were recruited as the control group. The mean T2RT and AEOMs in CAS positive group were higher than those in CAS negative group. Both CAS positive and negative groups had significantly higher mean T2RT and AEOMs than the control group（P〈0.01）. There was a positive correlation between T2RT and AEOMs values in GO patients, both of them had a positive correlation with CAS and the ophthalmic examinations. It was concluded that to evaluate the activity of GO, CAS was mostly related to inflammation symptoms of ocular surface, more than that, T2RT and AEOMs were also related to abnormal findings of the ophthalmic examinations including high ocular pressure, impaired eyeball movement, diplopia and proptosis. T2RT and AEOMs can reflex the inflammation state of ocular muscles better. CAS combined with 3D T2-mapping MR imaging could improve the sensitivity of detection of active GO so as the prediction and evaluation of the response to methylprednisolone treatment.展开更多

In the present study, we conducted a meta-analysis to examine this association. Two reviewers systematically searched eligible studies in Pub Med, Web of Science, Embase and China Biomedical Literature Database（CBM）. A meta-analysis on the association between GD and TSHR intron 1 rs179247 or rs12101255 was performed. The odd ratios（OR） were estimated with 95% confidence interval（CI）. Meta package in R was used for the analyses. Seven articles（13 studies） published between 2009 and 2014, involving 5754 GD patients and 5768 controls, were analyzed. The polymorphism of rs179247 was found to be associated with an increased GD risk in the allele analysis（A vs. G： OR=1.40, 95% CI=1.33–1.48） and all genetic models（AA vs. GG： OR=1.94, 95% CI=1.73–2.19; AA＋AG vs. GG： OR=1.57, 95% CI=1.41–1.74; AA vs. AG＋GG： OR=1.54, 95% CI=1.43–1.66）. The site rs12101255 also conferred a risk of GD in the allele analysis（T vs. C： OR=1.50, 95% CI=1.40–1.60） and all genetic models（TT vs. CC： OR=2.22, 95% CI=1.92–2.57; TT＋TC vs. CC： OR=1.66, 95% CI=1.50–1.83; TT vs. TC＋CC： OR=1.74, 95% CI=1.53–1.98）. Analysis of the relationship between rs179247 and Graves＇ ophthalmopathy（GO） showed no statistically significant correlation（A vs. G： OR=1.02, 95% CI=0.97–1.07）. Publication bias was not significant. In conclusion, GD is associated with polymorphisms of TSHR intron 1 rs179247 and rs12101255. There is no association between rs179247 SNPs and GO.展开更多

METHODS： We retrospectively examined 40 archived paraffin specimens from two teaching hospitals in Southern China between January 2007 and January 2015 that were pathologically determined to exhibit IOIP. Eleven concurrent paraffin specimens of thyroid-associated ophthalmopathy （TAO） composed the control group. In situ hybridization was performed to detect EBERs. Immunohistochemistry was employed to detect CD3, CD20, Vimentin, and smooth muscle actin （SMA）, and the positive rate, types of positive cells, and distribution and location of EBERs were evaluated. RESULTS： The positive expression rate of EBERs was 47.5% （19/40） in the IOIP group, which was significantly higher than that in the TAO group [0 （0/11）, P=-0.011]. in the IOIP group, the lymphocyte infiltrative subtype, fibrotic subtype, and mixed subtype exhibited EBER-positive rates of 57.1% （12121）, 12.5% （118）, and 54.5% （6/11）, respectively, and no significant differences were found between these subtypes （P=0.085）. Positive signals of EBERs were mainly present in medium-small lymphocytes between or around follicles and in the nuclei of activated immunoblasts （14/19）. CONCLUSION： The positive rate, types, and distribution of EBER-expressing cells in IOIP have been documented.These findings are conducive for a better understanding of the underlying mechanisms of Epstein-Barr virus infection in IOIP pathogenesis.展开更多
