The relationship between hope level and self-management behaviors in Chinese patients with type 2 diabetes mellitus: a chain-mediated role of social support and disease perception.

Background: Type 2 diabetes mellitus is a chronic disease and one of the fastest- growing global health emergencies of the 21st century. The relationships between hope level, social support, disease perception, and self-management behaviors are still unclear. Therefore, this study aimed to create a structural equation model to investigate the underlying mechanisms of self-management behaviors in patients with type 2 diabetes mellitus and provide a theoretical basis for future interventions.

Identification of floral aroma components and molecular regulation mechanism of floral aroma formation in Phalaenopsis.

Background: Most Phalaenopsis cultivars have almost no aroma, with a few exceptions. Phalaenopsis presents significant challenges in fragrance breeding due to its weak aroma and low fertility. It is therefore necessary to identify the aroma components and key regulatory genes in Phalaenopsis cultivars like 'Orange Beauty', 'Brother Sara Gold', 'Purple Martin', 'H026', 'SK16', 'SX098', and 'SH51', to improve the aroma of the common Phalaenopsis.

Preoperative irrigation and vacuum sealing drainage with antibiotic-containing drainage fluid of foot and ankle wounds improves outcome of reconstructive skin flap surgery.

Objectives: By observing the infection and soft tissue defect on the wound surface of the foot and ankle, this paper attempts to explore the effect of preoperative irrigation and vacuum sealing drainage with antibiotic-containing drainage fluid (abPI-VSD) on the bacterial quantity and the local inflammatory response at the flap, and further to provide a basis for applying this technique before a reconstructive skin flap surgery of foot and ankle wounds.

Methods: Seventy-five patients were randomly divided into two groups, and all surgeries were done by one physician. The flap reconstructions were done to 31 cases with the abPI-VSD being used (group A); the flap reconstructions were done to the rest 44 cases after wound cleaning using antibiotic irrigation solution without the use of the abPI-VSD (group B).

Meta-analysis of single-stage versus two-staged management for concomitant gallstones and common bile duct stones.

Objective: The purpose of this article was to compare the effectiveness and safety of single-stage (laparoscopic cholecystectomy [LC] plus laparoscopic common bile duct exploration [LCBDE]) with two-stage (LC plus endoscopic retrograde cholangiopancreatography (ERCP)/endoscopic sphincterotomy [EST]) in management for concomitant gallstones and common bile duct (CBD) stones.

Materials And Methods: Systematic review and meta-analysis of randomised controlled trials (RCTs) comparing outcomes following single-stage with two-stage management for concomitant gallstones and CBD stones published from 1990 to 2017 in PubMed, Embase and the Science Citation Index. The primary outcomes were stone clearance from the CBD, post-operative morbidity and mortality.
