The Sequential Mediating Roles of Body Pain and Self-Reported Health Status in the Relationship between Sleep Duration and Life Satisfaction.

Objective: This study examines the sequential mediating roles of body pain and self-reported health in the association between sleep duration and self-reported life satisfaction among elderly Chinese adults.

Methods: Data from the fifth wave of the China Health and Retirement Longitudinal Survey (CHARLS) were used to analyse the relationships between sleep duration and body pain, self-reported health, and life satisfaction through logistic regression and Restricted Cubic Spline (RCS) analyses. The sequential mediation effects of body pain and self-reported health status were examined chain mediation analysis.

Apelin/APJ-Manipulated CaMKK/AMPK/GSK3 Signaling Works as an Endogenous Counterinjury Mechanism in Promoting the Vitality of Random-Pattern Skin Flaps.

A random-pattern skin flap plays an important role in the field of wound repair; the mechanisms that influence the survival of random-pattern skin flaps have been extensively studied but little attention has been paid to endogenous counterinjury substances and mechanism. Previous reports reveal that the apelin-APJ axis is an endogenous counterinjury mechanism that has considerable function in protecting against infection, inflammation, oxidative stress, necrosis, and apoptosis in various organs. As an in vivo study, our study proved that the apelin/APJ axis protected the skin flap by alleviating vascular oxidative stress and the apelin/APJ axis works as an antioxidant stress factor dependent on CaMKK/AMPK/GSK3 signaling.

Tea consumption and colorectal cancer risk: a meta-analysis of prospective cohort studies.

Purpose: Data from in vitro and animal studies support the preventive effect of tea (Camellia sinensis) against colorectal cancer. Further, many epidemiologic studies evaluated the association between tea consumption and colorectal cancer risk, but the results were inconsistent. We conducted a meta-analysis of prospective cohort studies to systematically assess the association between tea consumption and colorectal cancer risk.

Glycyrrhizin inhibits osteoarthritis development through suppressing the PI3K/AKT/NF-κB signaling pathway in vivo and in vitro.

Osteoarthritis (OA) is a serious and frequently occurring disease in the elderly, characterized by cartilage degeneration and proliferation of bone structure. Glycyrrhizin, a compound extracted from licorice, has been reported to have various important biological activities, such as antioxidant properties and anti-inflammatory action. However, it has not been reported whether glycyrrhizin has a positive effect on OA development.

Proteomic and bioinformatic analysis of condyloma acuminata: mild hyperthermia treatment reveals compromised HPV infectivity of keratinocytes via regulation of metabolism, differentiation and anti-viral responses.

Background: Hyperthermia has proved successful in treating cutaneous human papillomavirus infectious diseases such as plantar wart and condyloma acuminata (CA). Moreover, this treatment provides improved therapeutic efficacy in these conditions as compared with conventional therapies.

Objectives: To investigate the global proteome changes in CA in response to hyperthermia and achieve a better understanding of the mechanisms of hyperthermia therapy against HPV-infectious diseases.

[The effects of neoadjuvant chemotherapy with cyclophosphamide on the plasma level of catecholamine in rats during perioperative period].

Objective: To investigate the effects of neoadjuvant chemotherapy on the response of surgical stress during perioperative period.

Methods: From July 2005 to June 2006, 30 SD rats with the same age were distributed into 3 experimental groups and 1 control group randomly. Each experimental group included 8 rats, and the control group included 6 rats.
