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.

Peptide-based radiopharmaceuticals targeting integrin α5β1 show promise for precise tumor diagnosis and treatment. However, current peptide-based radioligands that target α5β1 demonstrate inadequate in vivo performance owing to limited tumor retention. The use of PEGylation to enhance the tumor retention of radiopharmaceuticals by prolonging blood circulation time poses a risk of increased blood toxicity. Therefore, a PEGylation strategy that boosts tumor retention while minimizing blood circulation time is urgently needed. Here, we developed a PEGylation-enabled peptide multidisplay platform (PEGibody) for PR_b, an α5β1 targeting peptide. PEGibody generation involved PEGylation and self-assembly. [⁶⁴Cu]QM-2303 PEGibodies displayed spherical nanoparticles ranging from 100 to 200 nm in diameter. Compared with non-PEGylated radioligands, [⁶⁴Cu]QM-2303 demonstrated enhanced tumor retention time due to increased binding affinity and stability. Importantly, the biodistribution analysis confirmed rapid clearance of [⁶⁴Cu]QM-2303 from the bloodstream. Administration of a single dose of [¹⁷⁷Lu]QM-2303 led to robust antitumor efficacy. Furthermore, [⁶⁴Cu]/[¹⁷⁷Lu]QM-2303 exhibited low hematological and organ toxicity in both healthy and tumor-bearing mice. Therefore, this study presents a PEGibody-based radiotheranostic approach that enhances tumor retention time and provides long-lasting antitumor effects without prolonging blood circulation lifetime. The PEGibody-based radiopharmaceutical [⁶⁴Cu]/[¹⁷⁷Lu]QM-2303 shows great potential for positron emission tomography imaging-guided targeted radionuclide therapy for α5β1-overexpressing tumors.

Objective: To conduct a systematic review and meta-analysis of studies evaluating the oncological and fertility outcomes of early-stage endometrial cancer (EC) treated with the levonorgestrel-releasing intrauterine system (LIUS)-based regimens. Methods: The Meta-analyses Of Observational Studies in Epidemiology statement for meta-analyses was followed. Searches were conducted on MEDLINE, Embase, PubMed, Preprints, and the Cochrane Central Register of Controlled Trials from January 1990 to August 4, 2022. The Joanna Briggs Institute Critical Appraisal Checklist was used for quality assessment. The primary endpoint was the complete response (CR) rate and the secondary endpoints were relapse, pregnancy, and live birth rate. Results: A total of 25 studies (821 women) were included. The CR rate of LIUS-based regimens was 63.4% (95% confidence interval [CI]=52.3%–73.2%), with 29.6% (95% CI=23.3%–36.8%) of cases experiencing recurrence during follow-up. In sensitivity analyses, patients younger than 45 years of age with a body mass index <30 kg/m2 who were treated with LIUS-based regimens achieved a high CR rate of 84.6% (95% CI=80.3%–88.1%) over a median follow-up of more than 24 months. Overall pregnancy and live birth rates were 37.9% (95% CI=24.1%–53.9%) and 39.3% (95% CI=24.0%–57.0%), respectively. No statistical differences were apparent in CR or relapse rates among the LIUS+GnRH agonist, LIUS+oral progesterone, or hysteroscopic resection followed by LIUS subgroups. Conclusion LIUS-based therapies are viable for the conservative management of early-stage endometrioid EC on CR and fertility outcome.

Radiation-induced lung injury （RILI）， one of the common complications caused by radiotherapy， encompasses two phases： an early phase known as radiation pneumonitis （RP） and a late phase called radiation fibrosis （RF）， threatening the life and life quality of patients， with poor prognosis. Accumulating evidence has shown that the occurrence of RILI is related to a variety of cytokines and signaling pathways. This paper summarized the research on the effects of Chinese medicine on RILI from the perspective of cytokines and signaling pathways. Cytokines include transforming growth factor-β₁ （TGF-β₁）， interleukins （ILs）， tumor necrosis factor-α （TNF-α）， platelet-derived growth factor （PDGF）， vascular endothelial growth factor （VEGF）， and high mobility group box-1 （HMGB1）. Related signaling pathways are phosphatidylinositol-3-kinase/protein kinase B（PI3K/Akt） signaling pathway， mitogen-activated protein kinase （MAPK） signaling pathway， Wnt/β-catenin signaling pathway， Notch1/Jagged1 signaling pathway， and nuclear factor-E₂-related factor2/antioxidant response element （Nrf2/ARE） signaling pathway. Cytokines may interfere with RILI progression by initiating various downstream signaling pathways， such as TGF-β₁/Smads signaling pathway， TGF-β₁/VEGF signaling pathway， TNF-α/nuclear factor-κB （NF-κB） signaling pathway， and HMGB1/Toll-like receptor 4 （TLR4） signaling pathway. In recent years， many scholars have attempted to delay RILI progression by down-regulating the expression of cytokines， antagonizing the effect of cytokines or regulating signaling pathways. It has been verified that many Chinese medicines， Chinese medicine monomers， and compound Chinese medicine prescriptions can inhibit the release of some cytokines or regulate some signaling pathways to reduce the incidence/severity of RILI， with satisfactory therapeutic effects， which have attracted the interest of scholars.
