Microbiological isolates and associated complications of dacryocystitis and canaliculitis in a prominent tertiary ophthalmic teaching hospital in northern China.

Background: To report the microbiological isolates, aetiology, complications, antibiotic susceptibilities, and clinical remission of dacryocystitis and canaliculitis in a prominent tertiary ophthalmic teaching and referral hospital located in northern China and to offer appropriate recommendations for preventing and formulating drug treatment strategies.

Methods: This prospective study recruited a total of 477 participants who had been diagnosed with either dacryocystitis or canaliculitis. The cohort comprised 307 patients with chronic dacryocystitis, 111 patients with acute dacryocystitis, and 59 patients with canaliculitis.

Effects of the promoting bacterium on growth of plant under cadmium stress.

Cadmium (Cd) pollution is a huge threat to ecosystem health. In the manuscript, pot experiments were conducted to investigate the changes in plant biomass and antioxidant indicators under different cadmium pollution levels (0, 25, 50, and 100 mg/kg) of inoculation of plant growth-promoting bacteria ZG7 on sugar beet. The results showed that the accumulation of excess Cd in sugar beet exhibited different symptoms, including reduced biomass ( < 0.

Inoculation of Exogenous Complex Bacteria to Enhance Resistance in Alfalfa and Combined Remediation of Heavy Metal-Contaminated Soil.

Heavy metals are considered to be one of the main sources of soil contamination. In this study, three tolerant bacteria were isolated from the heavy metal-contaminated soil in mining area, and immobilized bacteria were constructed using corn straw as the carrier. The combined remediation effect of immobilized bacteria and alfalfa in pot experiments was explored in heavy metal-contaminated soil.

Effects of heavy metals on bacterial community structures in two lead-zinc tailings situated in northwestern China.

We evaluated the variations of bacterial communities in six heavy metal contaminated soils sampled from Yanzi Bian (YZB) and Shanping Cun (SPC) tailings located in northwestern China. Statistical analysis showed that both the heavy metals and soil chemical properties could affect the structure and diversity of the bacterial communities in the tailing soils. Cd, Cu, Zn, Cr, Pb, pH, SOM (soil organic matters), TP (total phosphorus) and TN (total nitrogen) were the main driving factors of the bacterial community variations.

Changes of Subfoveal Choroidal Thickness after Cataract Surgery: A Meta-Analysis.

Purpose: To investigate the effect of cataract surgery on subfoveal choroid thickness (SFCT) using enhanced-depth imaging optical coherence tomography (EDI-OCT).

Materials And Methods: Relevant publications were searched systematically through various databases from inception to March 2018. The unit of choroidal thickness measurements is micrometers.

Risk Factors for Retinal Redetachment After Silicone Oil Removal: A Systematic Review and Meta-Analysis.

Background And Objective: This systematic review and meta-analysis was made to measure risk factors for retinal redetachment (re-RD) after silicone oil removal (SOR) in a quantitative method.

Patients And Methods: A comprehensive literature review relating to risk factors for re-RD after SOR was conducted before March 2017. Odds ratio (OR) with 95% confidence interval (CI) was calculated after data combination.
