Complication rates and safety of pulsed dye laser treatment for port-wine stain: a systematic review and meta-analysis.

Pulsed dye laser (PDL) is the most commonly used method for port-wine stain (PWS); however, no studies have reported the safety of PDL. This review aimed to collect and summarize complications reported in relevant literature, assess complication rates in treating PWS with PDL, and explore the relevant influencing factors. A systematic review and meta-analysis were conducted to search for related studies in PubMed, Embase, and the Cochrane Library until August 2022.

Enhanced butanol production from cassava with Clostridium acetobutylicum by genome shuffling.

To obtain strains exhibiting high levels of solvent tolerance and butanol production, wild type strains of Clostridium acetobutylicum butanol-producing strain GX01 and Lactobacillus mucosae butanol-tolerant strain M26 were subjected to mutagenesis combining N-methyl-N-nitro-N-nitrosoguanidine induction with genome shuffling. After four successive rounds of genome shuffling, the C. acetobutylicum shuffled strain GS4-3 showing greater levels of fermentation performances (such as secreting a higher level of amylase, improving the thermal stability, and possessing greater environmental robustness) compared to the wild type strains was isolated.

High prevalence of impaired fasting glucose in Chinese children and adolescents with prehypertension/hypertension.

Aim: To assess the prevalence of impaired fasting glucose among Chinese children and adolescents with prehypertension/hypertension (PHP/HP), overweight/obesity (OW/OB) or both in the general population.

Methods: In total, 3409 children and adolescents among the age group of 10-18 years were enrolled. These subjects were then divided into four groups: OW/OB, PHP/HP, OW/OB + PHP/HP and a control group.

[The effects of epidermal growth factor on the wound repair of junctional epithelial cells and gingival epithelial cells in vitro].

Purpose: To study the effects of epidermal growth factor (EGF) on the proliferation and cellular fill of junctional epithelium (JE) and gingival epithelium (GE) by using an in vitro wound model.

Methods: EGFR mRNA was semiquantitatively determined by reverse transcriptase polymerase chain reaction (RT-PCR) and immunocytochemistry was performed to measure EGFR expression. JE and GE cells were plated into 6 well tissue culture plates containing 22mm x 26mm sterile glass coverslips.
