Association between interleukin-10 genetic polymorphisms and risk of primary open angle glaucoma in a Chinese Han population: a case-control study

AIM: To investigate the association between interleukin-10 (IL-10) genetic polymorphisms and risk of POAG through a case-control study in a Han population of China. METHODS: A total of 210 patients with POAG and 420 normal subjects were recruited during the period from Dec. 2013 to Dec. 2016. The IL-10 -1082A>G (rs1800870), -819T>C (rs1800871) and -592C>A (rs1800872) polymorphisms were determined using iPlex GOLD SNP genotyping analysis (the SequenomMassARRAY® System, Sequenom, San Diego, USA). The association between IL-10 -1082A>G (rs1800870), -819T>C (rs1800871), and -592C>A (rs1800872) polymorphisms and risk of POAG was assessed by singlelogistic regression analysis. RESULTS: We observed that those carrying the CC genotype of rs1800871 was associated with an increased risk of POAG when compared with those harboring the TT genotype (OR=1.84, 95%CI=1.01-3.38). Those with AA genotype of rs1800872 had a 10.62 fold risk of POAG in comparison to the CC genotype (OR=10.62, 95%CI, 3.41-33.09). A completely linkage disequilibrium was found between IL-10 rs1800871-rs1800872 (D’=1.00, r2=0.16). The A-C-A (OR=2.60, 95%CI, 1.48-4.58) and G-T-A (OR=2.34, 95%CI, 1.42-3.86) haplotypes were associated with an increased risk of POAG, while the A-T-C haplotype showed a decreased risk of POAG (OR=0.63, 95%CI, 0.49-0.81). CONCLUSION: Our data suggest that IL-10 rs1800871 and rs1800872 can be predictive factors for the pathogenesis of POAG in the Chinese population.     

联合激光与传统药物治疗原发性闭角型青光眼急性发作期的临床研究

目的评价激光周边虹膜成形术联合激光瞳孔成形术与传统降眼压药物治疗原发性闭角型青光眼急性发作的有效性和安全性。 方法收集2014年1月至2015年7月于邯郸市眼科医院(邯郸市第三医院)就诊的62例(68只眼)确诊为原发性闭角型青光眼首次急性发作并未做降眼压治疗患者的病例资料。其中,男性15例(17只眼),女性47例(51只眼),平均年龄(67.5±8.5)岁,所有患者眼压升高≥40 mmHg(1 mmHg＝0.133 kPa)。将入选患者采用数字表法随机分为激光组和药物组。激光组给予激光周边虹膜成形术联合激光瞳孔成形术治疗,药物组给予传统降眼压药物治疗。采用TA03型Icare眼压计测量治疗前、治疗后1 h和2 h的眼压,记录两组角膜及前房情况。以治疗后2 h眼压降至30 mmHg及以下为抢救成功,反之则为治疗失败。激光组和药物组年龄、就诊时眼压和发作时间等资料的描述采用均数±标准差表示,组间比较使用独立样本t检验;两组治疗成功率的描述采用眼数和百分比,比较采用χ²检验;两组治疗前、治疗后1 h和2 h眼压的比较采用两因素重复测量方差分析。 结果治疗后1 h激光组14只眼抢救成功,成功率为41.2%;药物组15只眼抢救成功,成功率为44.2%。治疗后2 h激光组18只眼抢救成功,成功率为52.9%;药物组20只眼抢救成功,成功率为58.2%。治疗后1 h与2 h两组间成功率无统计学意义( χ²＝0.06,0.24;P>0.05)。激光组治疗前视力为光感至0.4,治疗后1 h视力为眼前手动至0.6,治疗后2 h视力为眼前手动至0.6。药物组治疗前视力为光感至0.4,治疗后1 h视力为光感至0.8,治疗后2 h视力为光感至0.8。两组主要并发症为前房内炎症反应和角膜内皮皱褶,无眼内感染和脉络膜下暴发性出血等严重并发症。激光组治疗前、治疗后1 h和2 h平均眼压分别为(56.9±8.7)mmHg、(37.9±16.2)mmHg和(32.9±16.4)mmHg,治疗后眼压下降,与治疗前的比较差异有统计学意义(t＝6.02,7.76;P<0.05)。药物组治疗前、治疗后1 h和2 h平均眼压分别为(55.8±9.5)mmHg、(37.6±17.7)mmHg和(30.6±18.2)mmHg,治疗后眼压下降,与治疗前的比较差异有统计学意义(t＝5.28,7.16;P<0.05)。但两组各时间点的眼压比较均无统计学意义(t＝0.89,0.58,0.85;P>0.05)。 结论激光周边虹膜成形术联合激光瞳孔成形术和传统的降眼压药物治疗均能快速降低原发性闭角型青光眼急性发作期的眼压,但激光治疗安全、有效,可避免药物治疗给机体带来的副作用,是治疗原发性闭角型青光眼急性发作期的重要辅助措施。     

Alpha角对多焦点人工晶状体植入术后视觉质量影响

研究不同Alpha角对多焦点人工晶状体（MIOL）植入术后视觉质量的影响,指导功能性IOL的应用。方法：前瞻性临床研究。选取2016年12至2018年10月就诊于潍坊眼科医院行白内障超声乳化吸除联合MIOL植入术患者56例（74眼）,根据Alpha角大小（角膜上视轴与光轴的距离α）分为3组： A组12眼（0 mm<α≤0.2 mm）,B组38眼（0.2 mm<α≤0.4 mm）,C组24眼（α>0.4 mm）。术后随访3个月,记录裸眼远、中、近视力以及调制传递函数、眩光、光晕等情况。数据采用卡方检验、方差分析进行统计。结果：B组和C组光晕和眩光发生率高于A组,差异有统计学意义（χ2 =38.372,P=0.01）; 3组间术后3个月远、中、近视力比较差异无统计学意义（均P>0.05）;3组间MTF值在0～30 c/d范围差异无统计学意义（P>0.05）;夜间远视、重影、混合焦点、星芒的发生率差异均无统计学意义（均 P>0.05）。结论：当Alpha角大于0.4 mm时,植入MIOL会增加眩光和光晕的发生,所以Alpha角>0.4 需谨慎考虑使用MIOL。     

An unusual origin of the celiac trunk and the superior mesenteric artery in the thorax

The authors report a case of a 44‐year‐old male found to have unusual origins of the celiac trunk (CT) and superior mesernteric artrery (SMA) as revealed by routine multidetector computed tomograph (MDCT) angiography. The CT and SMA originate from the thoracic aorta (TA) 21 mm and 9 mm above the aortic hiatus, respectively. The median arcuate ligament (MAL) is located at the level of the L1–L2 intervertebral disc. The course of the CT descends in the thoracic cavity making a 14° acute downward angle in front of the TA; below the level of the MAL, the CT descends, making an angle of 47°. The course of the SMA descends at both the thoracic and abdominal level making an angle of 17°, and having an aortomesenteric distance of 9 mm at the level of the third part of the duodenum. In the present case, the supradiaphragmatic origin of the CT and the SMA was determined by their incomplete caudal descent, associated with a pronounced apparent descent of the diaphragm. A thoracic origin of the CT and SMA and the acute downward aortomesenteric angle (17°) associated with a reduced aortomesenteric distance at the level of the third part of the duodenum (9 mm), although no clinical signs are present, may predispose the patient to develop simultaneously a triple syndrome: the compression of CT by MAL (celiac axis compression syndrome), the compression of SMA by MAL (superior mesenteric artery compression syndrome), and the compression of the duodenum by the SMA (superior mesenteric artery syndrome).

Compartment syndrome and rhabdomyolysis as a positioning complication following retrosigmoid craniotomy

The goal of surgical positioning is to provide optimal surgical access and visualization while maintaining the patient's safety, with the least physiological compromise. Here, we report a 30-year-old man with an unremarkable past medical history who developed superior vena cava syndrome after a 15-hour retrosigmoid craniotomy for removal of a right cerebellopontine (CP) angle tumor. Compartment syndrome from the head to neck and rhabdomyolysis were recognized, with extensive swelling of his head and neck, markedly swollen soft tissues and necrosis of multiple muscles revealed by computed tomography, and very high concentrations of creatine kinase (CK) and aspartate transaminase. Immediate intensive care and rehabilitation therapy were provided and aimed at maintaining adequate perfusion/oxygenation and decreasing tissue pressure. He was successfully weaned from ventilation on postoperative day (POD) 25, transferred to a general ward on POD 29, and discharged with mild muscular and neurological sequelae on POD 51. Careful adjustment of surgical positioning is crucial for patient safety, especially when positioned at an extreme position in association with prolonged surgery.     

Suggestive evidence of genetic association of −572G > C polymorphism with primary open angle glaucoma in a North Indian Punjabi population

BackgroundIL6 is an important candidate gene implicated in the pathogenesis of glaucoma. The present study assessed the genetic association of −174G > C and −572G > C polymorphisms in the IL6 promoter region with primary open angle glaucoma (POAG) and primary angle closure glaucoma (PACG) in a north Indian Punjabi cohort.Methods910 subjects (313 POAG, 148 PACG cases and 449 controls) were recruited. Genotyping was done by TaqMan assays. Genetic association was tested under different genetic models using Plink. Diplotype and linkage disequilibrium (LD) analysis was done through Haploview. Association of clinical parameters with the genotypes was assessed by one-way ANOVA. Adjustment for potential confounding variables was done by binary logistic regression. IL6 levels were measured in POAG patients and controls.Results572G > C variant showed marginal difference in genotype frequency between pooled cases and POAG subgroup with respect to controls (p = 0.042; OR = 1.33; and p = 0.041; OR = 1.37). The GC genotype conferred 1.37-fold protection under codominant model in POAG cases (p = 0.034, OR = 1.37, 95% CI = 1.02–1.85; p_corr = 0.025, OR = 1.45, 95% CI = 1.04–2.02). The mean value for IOP was elevated among cases having ‘CC’ genotype at the −572G > C locus (p = 0.037).Lower levels of IL6 were detected in POAG patients in plasma samples (p = 0.0001).ConclusionThe study reports suggestive evidence for −572G > C variant in IL6 in affecting genetic susceptibility to POAG in the targeted North Indian Punjabi cohort. A correlation of IL6 levels in aqueous humor (AH) and systemic circulation in POAG was observed, the functional and diagnostic relevance of which may be further investigated.
