To systematically analyzed the reporting status of core elements in publicly available clinical practice guideline(hereafter referred to as "guideline") protocols published domestically and internationally over the past decade, identified existing problems, and provided evidence to inform the standardized writing and publication of future guideline protocols. A systematic search was conducted in Chinese and English databases for clinical practice guideline protocols published during the past ten years. The basic characteristics and reporting of core elements—including registration information, conflict of interest management, evidence grading, development process and timeline planning, as well as dissemination and implementation—were extracted and analyzed. Chi-square tests were performed to explore associations between protocol characteristics and the reporting of core elements. A total of 94 guideline protocols were included, of which 67 were in Chinese(71.28%) and 27 were in English(28.72%). Overall, 82.98% of the guideline protocols were registered, 92.55% reported management of conflicts of interest, 97.87% reported evidence searching, 88.30% reported evidence grading, and 89.36% described dissemination and implementation strategies. However, only 55.32% reported the guideline development process, and merely 23.40% reported timeline planning. Further analysis indicated that the reporting of registration, evidence searching, development process, and timeline planning was associated with year of publication. Differences were observed between domestic and international guidelines in reporting registration, conflict of interest management, development process, time planning, and dissemination and implementation. Guidelines intended for development exhibited higher reporting rates for registration, development process, and dissemination and implementation compared to those planned for updating or adaptation. Although current guideline protocols demonstrate relatively adequate reporting of methodological elements, deficiencies remain in development process and timeline planning. Future efforts should focus on promoting the publication and standardized reporting of guideline protocols, enhancing the international recognition of registration platforms, and strengthening the development process and timeline planning to advance the scientific rigor and transparency of guideline development.

Myocardial infarction (MI) and osteoporosis (OP), as two prevalent metabolic diseases with high morbidity and mortality rates, are respectively characterized by cardiovascular system dysfunction and bone homeostasis imbalance, collectively posing significant global public health challenges. While clinically often considered as independent diseases, recent studies have revealed shared pathological mechanisms between the two. This study initiated its exploration from the traditional Chinese medicine concept of the "heart-bone" axis, systematically analyzing the correlation between MI and OP from perspectives including hemodynamics, neuroendocrinology, calcium homeostasis, inflammation and vascular injury, as well as hormone levels. By discussing the pathological mechanisms of "heart disease affecting the bones and bone disease affecting the heart", the study also elucidated advancements in both Western and traditional Chinese medicine treatments. The goal is to provide novel insights and methodologies for the prevention and treatment of "heart-bone comorbidities", thereby facilitating comprehensive management of cardiovascular and skeletal diseases.

Health economics evidence plays an important role in linking clinical value evidence with health resource allocation decisions in the development of clinical practice guidelines. It can not only effectively balance clinical effectiveness and economic feasibility but also avoid forming "idealized" recommendations that are detached from the affordability of the healthcare system or the burden-bearing capacity of patients. To promote guideline developers to use health economics evidence more standardizedly and fully, this paper conducts an in-depth analysis of the current application status, existing challenges, access channels, and application processes of health economics evidence in current guidelines, and on this basis, puts forward considerations and suggestions for strengthening and standardizing the application of health economics evidence in China's clinical practice guidelines.

ObjectiveTo investigate the potential mechanism of heat-sensitive moxibustion on chronic atrophic gastritis (CAG) through the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) signaling pathway. MethodsFifty-eight SD rats were randomly divided into blank group (n=14) and modeling group (n=44). Rats in the blank group were fed routinely, while the rats in the modeling group received drinking water containing 1-methyl-3-nitro-1-nitrosoguanidine (MNNG) at a concentration of 140 μg/ml, combined with irregular fasting and feeding for 12 weeks to establish CAG model. After successful modeling, the rats were randomly divided into model group (n=10), inhibitor group (n=10) and moxibustion group (n=20). After 40 minutes of suspended moxibustion at "Zhongwan" (CV 12) daily, the rats in the moxibustion group were divided into heat-sensitive moxibustion group (n=10) and non-heat-sensitive moxibustion group (n=9) according to the change of tail temperature during moxibustion. The inhibitor group was bound for 40 minutes daily, and then administered with PI3K/Akt signaling pathway inhibitor, rapamycin solution, by gavage at a dose of 1 mg/kg. The model group received intragastric administration of 1 ml/kg normal saline after 40 minutes of restraint stress each day. All interventions were administered once daily for 28 consecutive days, while the blank group received no intervention. After the intervention finished, the body weight of rats in each group was compared. HE staining was used to observe the histopathological changes of gastric mucosa. The apoptosis-positive rate of gastric mucosal cells was detected by TUNEL assay. Immunohistochemistry was performed to determine the protein levels of matric metalloproteinase-7 (MMP7), vascular endothelial growth factor A (VEGFA) and epidermal growth factor receptor (EGFR) in gastric mucosa. The mRNA expression levels of PI3K, Akt and mammalian target of rapamycin (mTOR) in gastric mucosal tissues were detected by qPCR. The protein levels of phosphorylated Akt (p-Akt) and phosphorylated mTOR (p-mTOR) in rat gastric mucosal tissues were measured by Western Blotting. ResultsCompared to the blank group, rats in all other groups exhibited decreased body weight, significantly increased gastric mucosal cell apoptosis-positive rates, elevated protein levels of MMP7, VEGFA and EGFR in gastric mucosa, increased mRNA expression levels of PI3K, Akt and mTOR, and enhanced protein expression levels of p-Akt and p-mTOR (P<0.05 or P<0.01). Histopathological examination revealed thinning of the gastric mucosa, glandular disorganization and atrophy, accompanied by intestinal metaplasia.Compared to the model group, the heat-sensitive moxibustion group, the non-heat-sensitive moxibustion group and the inhibitor group all showed significant improvements in the above-mentioned indicators (P<0.05 or P<0.01). Compared to the heat-sensitive moxibustion group, the non-heat-sensitive moxibustion group and the inhibitor group exhibited increased positive rates of gastric mucosal cell apoptosis; the non-heat-sensitive moxibustion group showed increased protein levels of MMP7, VEGFA and EGFR, as well as mRNA expression levels of PI3K, Akt and mTOR, and protein expressions of p-Akt and p-mTOR; the inhibitor group exhibited elevated protein expression level of EGFR (P<0.05 or P<0.01). Histopathological examination showed that the gastric mucosal glands in the heat-sensitive moxibustion group were arranged more regularly, with an approximately normal structural appearance. ConclusionHeat-sensitive moxibustion can improve the body weight of CAG rats and repair gastric mucosal injury. Its therapeutic effects may be mediated by inhibiting excessive activation of gastric mucosal PI3K/Akt signaling pathway, thereby reducing gastric mucosal cell apoptosis.

Clinical practice guidelines serve as a crucial bridge linking research evidence, clinical practice, and health policy decision-making. However, the guideline domain continues to face persistent challenges, including duplicate guideline development, variable methodological quality, lack of transparent reporting, insufficient implementation and translation, and delayed updates. Focusing solely on "how to develop a high-quality guideline" is no longer sufficient to meet the modern healthcare system's demands for timely, trustworthy, actionable, and dynamically updated recommendations. The emergence of the guideline ecosystem marks a shift in guideline research and practice from a linear development process toward a more systematic governance model. Rooted in the evidence ecosystem, the guideline ecosystem has its own distinct functional positioning, encompassing recommendation formulation, clinical implementation, and life-cycle updating. Looking ahead, China should leverage guideline registries, integrated quality assessment systems, implementation science, dynamic updating mechanisms, and artificial intelligence technologies to promote the transformation of its guideline system from scale expansion to an ecosystem-based model characterized by high quality and sustainability.

Objective:To explore the dosimetry optimization strategy based on filter thickness and shape selection for the bulb superficial X-ray radiotherapy unit.Methods:Monte Carlo code TOPAS was used to model tubular equipment, and the dose distribution from six X-ray energies (50-150 kV) and five conventional aluminum filters (0.5-3.0 mm) with different thickness were simulated in the water model. The percentage depth dose (PDD) curve along the central axis, the center-axis profile dose at different depths, and the lateral dose distribution were analyzed. The dose distribution of three different designs of aluminum filters (conventional cylindrical, conical and oblique cylindrical filters) was compared to evaluate the effect of dosimetric optimization of different filter shapes.Results:Under the same energy, increasing the thickness of the filter can optimize the superficial skin dose, and the optimization effect of depth dose uniformity can be increased by 26% at a depth of 5.5 mm at 70 kV energy. The raised, flat and inclined dose distribution modes can be achieved by using conventional cylindrical, conical and inclined aluminum filters.Conclusions:By selecting the appropriate X-ray energy and filter thickness, an ideal dose distribution matching the tumor depth can be achieved. The application of personalized filters is also of great significance for diverse target areas.
