Re-positioning pretarsal tissue layers for double-eyelid surgery: 6-year experience.

Double-eyelid surgery is a very common practice in East Asian patients. The differential distribution of pretarsal tissue layers is considered to be the anatomical mechanism of natural Asiatic single eyelid, it is possible to form double-eyelid crease by re-positioning the pretarsal structure layers. The author presents a new double-eyelid surgery based on re-positioning of the pretarsal structure layers without tissue removal.

Novel phosphate-solubilizing bacteria enhance soil phosphorus cycling following ecological restoration of land degraded by mining.

Little is known about the changes in soil microbial phosphorus (P) cycling potential during terrestrial ecosystem management and restoration, although much research aims to enhance soil P cycling. Here, we used metagenomic sequencing to analyse 18 soil microbial communities at a P-deficient degraded mine site in southern China where ecological restoration was implemented using two soil ameliorants and eight plant species. Our results show that the relative abundances of key genes governing soil microbial P-cycling potential were higher at the restored site than at the unrestored site, indicating enhancement of soil P cycling following restoration.

Mild to moderate blepharoptosis correction: Outcomes of levator aponeurosis posterior layer plication.

Conventional levator aponeurosis plication is a widely accepted technique for correction of mild to moderate ptosis. However, this method is associated with a high recurrence rate. The objective of this study was to investigate the clinical efficacy of levator aponeurosis posterior layer plication technique for correction of mild to moderate ptosis.

Inhibition of SMP30 gene expression influences the biological characteristics of human Hep G2 cells.

Senescence marker protein 30 (SMP30), a hepatocellular carcinoma (HCC) associated antigen had been identified by our research group. To study its mechanisms of regulation and associations with the occurrence and development of HCC, we inhibited expression by RNAi technique, and observed effects on the biological characteristics of Hep G2 cells. In cell viability assays, cell growth in the experimental group (with siRNA transfection) was elevated.

Soluble expression of recombinant human SMP30 for detecting serum SMP30 antibody levels in hepatocellular carcinoma patients.

Senescence marker protein 30 (SMP30), a hepatocellular carcinoma (HCC) associated antigen, was earlier shown by our research group to be highly expressed in HCC paracancerous tissues, but have low levels in HCC tissues. In order to detect anti-SMP30 antibody in serum of HCC patients, we established pET30a-SMP30 and pColdIII-SMP30 expression systems in Escherichia coli. However, the expression product was mainly in the form of inclusion bodies.
