AIM: To conduct a Meta-analysis pooling randomized controlled trials(RCTs) to compare hydrophobic with hydrophilic acrylic intraocular lenses in terms of posterior capsule opacification(PCO) ***: Electronic databases including PubMed,Embase, and the Cochrane Library were queried from their starting till January 2020. RCTs investigating the impact of hydrophobic versus hydrophilic acrylic intraocular lenses on PCO were considered eligible in this study. The pooled effect estimates were calculated using the random-effects ***: Thirteen RCTs comprising of 939 patients(1263 eyes) were covered in this study. Patients with hydrophobic acrylic intraocular lenses had a lower PCO score than those with a hydrophilic acrylic intraocular lenses [standard mean difference:-1.80;95% confidence interval(CI):-2.62 to-0.98;P<0.001]. Moreover, the frequency of neodymium-doped yttrium aluminum garnet(Nd:YAG)capsulotomy in patients with hydrophobic acrylic intraocular lenses was significantly lower than patients with hydrophilic acrylic intraocular lenses(relative risk: 0.38;95%CI: 0.20-0.71;P=0.003).CONCLUSION: These findings suggest that hydrophobic acrylic intraocular lenses are superior to hydrophilic acrylic intraocular lenses in patients after cataract surgery due to lower PCO score and reduced Nd:YAG capsulotomy. While similar studies are conducted by other researchers, the present study conducted subgroup analyses that show superior results with hydrophobic lenses in trials conducted in western countries.

Outbreaks of severe virus infections with the potential to cause global pandemics are increasingly concerning. One type of those commonly emerging and re-emerging pathogens are coronaviruses(SARS-Co V, MERS-Co V and SARS-Co V-2).Wild animals are hosts of different coronaviruses with the potential risk of cross-species transmission. However, little is known about the reservoir and host of coronaviruses in wild animals in Qinghai Province, where has the greatest biodiversity among the world's high-altitude regions. Here, from the next-generation sequencing data, we obtained a known beta-coronavirus(beta-Co V) genome and a novel delta-coronavirus(delta-Co V) genome from faecal samples of 29 marmots, 50 rats and 25 birds in Yushu Tibetan Autonomous Prefecture, Qinghai Province, China in July 2019. According to the phylogenetic analysis, the beta-Co V shared high nucleotide identity with Coronavirus HKU24. Although the novel delta-Co V(Mt Co V) was closely related to Sparrow deltacoronavirus ISU42824, the protein spike of the novel delta-Co V showed highest amino acid identity to Sparrow coronavirus HKU17(73.1%). Interestingly, our results identified a novel host(Montifringilla taczanowskii) for the novel delta-Co V and the potential cross-species transmission. The most recent common ancestor(t MRCA) of Mt Co Vs along with other closest members of the species of Coronavirus HKU15 was estimated to be 289 years ago. Thus, this study increases our understanding of the genetic diversity of beta-Co Vs and deltaCo Vs, and also provides a new perspective of the coronavirus hosts.
