Correlation analysis of exercise volume and musculoskeletal disorders in people with income level differences: research based on the 2011-2018 NHANES dataset.

Objectives: Socioeconomic factors significantly impact human health; however, the impact of exercise and income on musculoskeletal system health remains unclear. Our study aims to explore the relationship between exercise and income with musculoskeletal system health in young and middle-aged adults.

Design: This cross-sectional study used data from 7,515 adults aged 20-59 years, which were obtained from the US NHANES, 2011-2018.

Association between healthy lifestyle and frailty in adults and mediating role of weight-adjusted waist index: results from NHANES.

Background: The relationship between healthy lifestyle and frailty remains unclear. Healthy weight is crucial for overall well-being, but using body mass index (BMI) to evaluate weight management is inefficient. This study clarifies the association between healthy lifestyle or its factors (non-smoking, moderate drinking, healthy weight, healthy diet, sufficeint physical activity, and non-sedentary) and frailty, and the feasibility of using the weight-adjusted waist index (WWI) reflecting central obesity as an intermediate indicator.

High molecular weight hyaluronic acid-liposome delivery system for efficient transdermal treatment of acute and chronic skin photodamage.

Photodamage is one of the most common causes of skin injury. High molecular weight hyaluronic acid (HHA) has shown immense potential in the treatment of skin photodamage by virtue of its anti-inflammatory, reparative, and antioxidative properties. However, due to its large molecular structure of HHA, HHA solution could only form a protective film on the skin surface in conventional application, failing to effectively penetrate the skin, which necessitates the development of new delivery strategies.

Mild photothermal therapy assist in promoting bone repair: Related mechanism and materials.

Achieving precision treatment in bone tissue engineering (BTE) remains a challenge. Photothermal therapy (PTT), as a form of precision therapy, has been extensively investigated for its safety and efficacy. It has demonstrated significant potential in the treatment of orthopedic diseases such as bone tumors, postoperative infections and osteoarthritis.

Nitric oxide synergizes minoxidil delivered by transdermal hyaluronic acid liposomes for multimodal androgenetic-alopecia therapy.

Androgenetic alopecia (AGA) is a common clinical condition, affecting over 200 million people globally each year. For decades, Minoxidil (Mi) tincture has been the primary treatment for this disease, but its low utilization rate and significant side effects necessitate new therapeutic strategies. Nitric oxide (NO) is a signaling molecule in various physiological processes, including vasodilation, immune responses, and cell proliferation.

Bacteria-Targeted Combined with Photothermal/NO Nanoparticles for the Treatment and Diagnosis of MRSA Infection In Vivo.

Currently, undeveloped diagnosis and delayed treatment of bacteria-infected sites in vivo not only expand the risk of tissue infection but are also a major clinical cause of multiple drug-resistant bacterial infections. Herein, an efficient nanoplatform for near-infrared (NIR)-light-controlled release and bacteria-targeted delivery of nitric oxide (NO) combined with photothermal therapy (PTT) is presented. Using maltotriose-decorated mesoporous polydopamine (MPDA-Mal) and BNN6, a smart antibacterial (B@MPDA-Mal) is developed to combine bacterial targeting, gas-controlled release, and PTT.

Dynamic nitric oxide/drug codelivery system based on polyrotaxane architecture for effective treatment of Candida albicans infection.

The low permeability of antifungal agents to fungal biofilms, which allows the continued survival of the fungus inside, is a key issue that makes fungal infections difficult to cure. Inspired by the unique dynamic molecule motion properties of the polyrotaxane (PR) nanomedicine, herein, a dynamic delivery system Clo@mPRP/NONOate was fabricated by co-loading nitric oxide (NO) and the antifungal drug clotrimazole (Clo) onto the α-cyclodextrin (α-CD) PR modified mesoporous polydopamine (mPDA) nanoparticles, in which pentaethylenehexamine (PEHA) was grafted to α-CDs. The cationic α-CDs endowed this dynamic NO/Clo codelivery system with the ability to effectively attach to fungal biofilms through electrostatic interaction, while the introduction of PRs with flexible molecule motion (slide and rotation of CDs) enhanced the permeability of nanoparticles to biofilms.

Superficial and multiple calcifications and ulceration associate with intraplaque hemorrhage in the carotid atherosclerotic plaque.

Objective: Intraplaque hemorrhage (IPH) and ulceration of carotid atherosclerotic plaques have been associated with vulnerability while calcification has been conventionally thought protective. However, studies suggested calcification size and location may increase plaque vulnerability. This study explored the association between calcium configurations and ulceration with IPH.

[Eighteen years activity in prevention of blindness in the district of Shunyi, Beijing].

Objective: To investigate how the urban tertiary hospital and medical research unit cooperate with rural basic medical unit in creating the model zone in prevention of blindness.

Methods: Peking Union Medical College Hospital (PUMCH) and Shunyi District Bureau of Public Health exerted their advantages to persist and popularize the program for prevention of blindness. A collaborative program in prevention of blindness was conducted by PUMCH and Shunyi District Bureau of Public Health.
