Long noncoding RNAs (lncRNAs) have been reported to play vital roles in various human cancers. The aim of this study was to explore the critical role of lncRNA HOXA11-AS in uveal melanoma (UM) progression. Briefly, we found that HOXA11-AS is overexpressed in UM tissues and cells; HOXA11-AS could regulate UM cell growth, invasion, and apoptosis. Mechanistically, RNA immunoprecipitation demonstrated that HOXA11-AS could simultaneously interact with enhancer of zeste homolog 2 (EZH2) to suppress its target p21 protein expression. In addition, we demonstrated that HOXA11-AS functioned as a molecular sponge for miR-124, and overexpression of miR-124 attenuated the proliferation and invasion-promoting effect of HOXA11-AS. Collectively, our findings reveal an oncogenic role for HOXA11-AS in UM tumorigenesis.

LSV is valuable in reducing the incidence of postoperative hydrocele, with similar recurrence and catch-up growth rates as LNSV. A series of RCTs are warranted to explore the efficacy of LSV in the management of varicocele in children and adolescents.

The body changes markedly during pregnancy; each system behaves differently from a nonpregnant state. As the eyes are the only windows to see directly what is going on in the internal environment, more and more researches have been done to explain the association between ocular changes and the physiological and pathological changes during pregnancy. The choroid is one of the critical parts of the eye, providing nutrition. And abnormal choroid may result in ocular dysfunction and visual problems. As the optical coherence tomography develops, a rapid, direct, noninvasive, and nontoxic way is available to obtain the choroid situation of pregnant women, which may explain the mechanism of pregnancy-related eye diseases. This review would summarize relevant original articles published from January 1, 2008 to December 1, 2016 to assess the changes of choroidal thickness (CT) with enhanced depth imaging optical coherence tomography (EDI-OCT) during pregnancy. And the relationship between choroidal thickness changes and pregnancy remains uncertain. To our knowledge, this is the first review of EDI-OCT in assessing the choroidal thickness of the pregnant women.

Purpose: To investigate the association of interleukin (IL)-6 with proliferative diabetic retinopathy (PDR) of type 2 diabetes (T2D) in a Chinese population. Methods: Two subtypes of the IL-6 promoter (-174 and -572 G/C) were genotyped in 215 T2D patients with PDR and 207 T2D patients with a normal retinal function (controls) using the PCR-RFLP method. The mRNA and protein expression of IL-6 was examined by real-time PCR. Results: T2D patients with PDR had a significantly higher frequency of IL-6 -174 GC (OR 0.58; 95% CI 0.34-0.99; p = 0.011) and IL-6 -572 GG (OR 0.53; 95% CI 0.24-1.14; p = 0.016) than T2D controls. The mRNA expressions of the rs1800795 GC and rs1800796 GG genotype were significantly increased compared to other cases (Fsig = 0.002, p = 0.001, respectively), followed by a relative increase in IL-6 in protein. Conclusions: IL-6 genotypes of rs1800795 GC and rs1800796 GG might point to a relatively high risk for T2D patients suffering from PDR in a Chinese population and they were associated with elevation of IL-6 expression in both mRNA and protein.

We conducted a meta-analysis of analytic and observational studies to evaluate the association between smoking and epiretinal membrane (ERM). The pertinent studies were identified via a literature search using three databases (MEDLINE, Cochrane Library, Embase) and the reference lists of retrieved studies. Cohort, case-control and cross-sectional studies meeting the predefined criteria were included. We extracted the odds ratios (OR) and 95% confidence intervals (CI) from each study. Overall risk estimates were pooled using random-effects models. Subgroup analyses based on several stratified factors were also performed. Two cohort studies and six cross-sectional studies involving 46,837 subjects were included. The pooled effect of all eight studies showed an unexpected significant decreased association between smoking and the occurrence of ERM (OR, 0.72; 95% CI 0.61–0.84; p = 0.29, I2 = 17.9%). Subgroup analyses supported this finding, except for the age-unadjusted group (OR, 0.87; 95% CI 0.63–1.22), the ERM classification group (cellophane macular reflex (CMR) OR, 0.93; 95% CI 0.68–1.28; preretinal macular fibrosis (PMF) OR, 0.74; 95% CI 0.41–1.32), the Asian group (OR, 0.75; 95% CI 0.52–1.09) and the past smoker group (OR, 1.02; 95% CI 0.85–1.22). The pooled effects from the current literature suggested a declining association between smoking and ERM, which requires further studies to confirm.
