Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

OBJECTIVETo observe the soft tissue regeneration after implantation of two novel citric acid-based biodegradable materials in the skull defects in rats.

METHODSTwo novel citric acid-based biodegradable materials were implanted in the muscular tissues in the thigh and harvested 2 weeks later. Another 40 rats with surgically induced cranial defect were randomized into control group, autograft group, CUPE-HA group, and POC-HA group (n=10), and 3 months after implantation, the materials were harvested for histological and morphometric analyses.

RESULTSSoft tissue regeneration was stimulated by the two biodegradable materials in the muscular tissues. The implants also stimulated angiogenesis and soft tissue regeneration in the cranial defect and accelerated of intramembranous ossification.

CONCLUSIONThe 2 novel citric acid-based biodegradable materials can induce angiogenesis and soft tissue regeneration and accelerate intramembranous ossification in rats with cranial defects.

Objective To explore the expression of protease activated receptors (PARs) on human monocytes. Methods Flow cytometry and RT - PCR was used to detect the expressions of PARs on human monocytes that purified by MACS. Results FACS analysis showed that monocytes expressed PAR - 1 , PAR - 3 , PAR - 4, but not PAR - 2.RT - PCR revealed that monocytes expressed PAR - 1 and PAR -3, but not PAR -2 and PAR -4 mRNA. Conclusion PARs is expressed on human monocyte cells,which may facilitate further investigation of the potential functions of PARs on monocytes.
