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.

The importance of consensus research in medical decision-making has become increasinglyprominent. However, this field has long lacked unified terminology definitions and reporting standards, leading to significant heterogeneity in study design, implementation, and result presentation that affects the credibility and reproducibility of outcomes. The ACCurate COnsensus Reporting Document (ACCORD) in the field of biomedical research provides a structured writing framework for various consensus methods such as the Delphi method and nominal group technique, aiming to enhance the completeness and transparency of study reports. Combined with specific cases, this article interprets the core items of ACCORD, offering references for the design, implementation, and reporting of high-quality consensus research in China.

Background Indoor air quality directly affects people's health, especially the impact of chemical pollutants in residential indoor air on children and the elderly is more significant. Objective To understand the pollution status of common chemical pollutants in residential indoor air in Shijiazhuang, evaluate the health risks of chemical pollutants to school-age children and the elderly, and provide reference for controlling indoor pollution in residential environment. Methods Using stratified random sampling, a total of 60 households were selected from 2 urban areas and 1 surrounding rural area in Shijiazhuang City, specifically in July 2023 (non-heating season) and December 2023 (heating season), respectively. Relevant data was collected through on-site sampling [including CO, CO2, PM10, PM2.5, NO2, SO2, O3, ammonia, formaldehyde, benzene, toluene, xylene, total volatile organic compounds (TVOC), trichloroethylene, and tetrachloroethylene] and survey questionnaires. The pollutant concentrations were evaluated following the Standards for indoor air quality of GB/T 18883-2022, and the inhalation exposure risks of the target population were assessed based on the health risk assessment method. Results In the indoor air of the urban and rural residence in Shijiazhuang City, except for CO, NO2, SO2, toluene, and xylene, which did not exceed the standard limits, other pollutants showed varying degrees of exceedance. The non-qualified rates of PM10, PM2.5, and CO2 in the urban areas were higher than those in the rural areas (P < 0.05). The seasonal difference analysis showed that the non-qualified rates of PM2.5, PM10, CO2, trichloroethylene, and tetrachloroethylene in the urban areas were higher in the heating season than in the non-heating season (P<0.05); the non-qualified rates of ammonia and formaldehyde in the rural areas increased significantly in the non-heating season(P<0.05). The health risk assessment indicated that the maximum hazard quotient (HQ) of tetrachloroethylene for the elderly exceeded 1, while the HQ values for ammonia, formaldehyde, benzene, toluene, xylene, and trichloroethylene remained below 1 for either children or the elderly. For carcinogenic risks, the median carcinogenic risk (CR) of formaldehyde for school-aged children or the elderly fell within the range of 10−6-10−4, whereas the median CR values for benzene, trichloroethylene, and tetrachloroethylene were all below 10−6. Conclusion The primary indoor air pollutants exceeding the national standard limits in residential areas of Shijiazhuang City include CO2, PM10, TVOC, PM2.5, formaldehyde, ammonia, trichloroethylene, and tetrachloroethylene. The levels of these pollutants exhibit significant urban-rural and seasonal variations. Special attention should be paid to the non-carcinogenic risk of tetrachloroethylene to the elderly and the carcinogenic risks of formaldehyde to school-age children and the elderly.

Objective:To explore the dosimetric characteristics of proton and photon radiotherapy in the treatment of breast cancer.Methods:Four female breast cancer patients who needed radiotherapy at Shandong Cancer Hospital and Institute from January 2024 to May 2024 were selected as the research subjects. The target area ranges of 4 patients were left-sided breast cancer with lymph node involvement, left-sided breast cancer with lymph node involvement and internal mammary node, right-sided breast cancer with lymph node involvement and internal mammary node and synchronous bilateral breast cancer. Intensity modulated proton therapy (IMPT) and intensity modulated radiation therapy (IMRT) plans were designed respectively based on the prescribed dose in the target area and the limits of organs at risk (tomotherapy plan for bilateral breasts). The conformity index (CI), homogeneity index (HI), gradient index (GI) and organs at risk doses were evaluated. The dosimetric characteristics of IMPT and photon radiotherapy were compared.Results:Both IMPT and photon radiotherapy plans of the 4 breast cancer cases met the clinical dose requirements. The HI value of IMPT plans (0.10-0.14) was comparable to that of photon radiotherapy plans (0.10-0.12), and the average CI of the photon radiotherapy plans was 0.10 higher than that of the IMPT plans, and the average GI was 0.55 lower than that of the IMPT plans. The D mean of ipsilateral lung and heart of IMPT was lower, especially in the low-dose area (V 0-3), which was significantly lower than the photon radiotherapy plans, D mean of ipsilateral lung was reduced by 12.2%, 6.1%, 16.1% and 34.8%, respectively, D mean of heart was reduced by 47.2%, 57.0%, 72.4% and 83.0%, respectively. The ipsilateral lung V 20 of IMPT was not lower than photon radiotherapy plans (unilateral breast: IMPT was 30.0%-34.0%, IMRT was 29.0%-35.9%) . Conclusions:IMPT significantly reduces the D mean to the ipsilateral lung and heart while ensuring dose coverage of the target in breast cancer, preventing more volume of surrounding normal tissues from being irradiated. However, IMPT does not show much more advantage than photon radiotherapy plans in the ipsilateral lung V 20.

ObjectiveTo investigate the effects of three traditional Chinese medicine formulas for nourishing kidney Yin on the occurrence of breast cancer, including Zuoguiwan(ZGW), Liuwei Dihuangwan(LWDHW) and Erzhiwan(EZW), and to explore their preventive mechanisms from the phagocytic function of macrophages. MethodsTen-month-old post-breeding female mice were randomly divided into the blank group, soy isoflavone group(0.13 g·kg-1·d-1, mixed with feed), ZGW group(2.34 g·kg-1·d-1), LWDHW group(0.56 g·kg-1·d-1), and EZW group(4.68 g·kg-1·d-1). The mice were palpated every 3 d until the age of 18 months, and those with detected lumps were confirmed for tumor development through hematoxylin-eosin(HE) staining, and the incidence of breast cancer in mice was calculated. A total of 40 SPF-grade female SD rats were randomly divided into the blank serum group(physiological saline), ZGW drug-containing serum group(16.20 g·kg-1·d-1of ZGW), LWDHW drug-containing serum group(3.89 g·kg-1·d-1 of LWDHW) and EZW drug-containing serum group(32.40 g·kg-1·d-1 of EZW), each group was orally administered 3 times a day for 5 consecutive days. On the 5th day, blood was collected from the abdominal aorta 1 h after the last gavage to prepare drug-containing serum. The effect of drug-containing serum with different concentrations on the viability of RAW264.7 cells was assessed by cell counting kit-8(CCK-8). Taking 20% of drug-containing serum concentration as the research object, its effect on the expression levels of major histocompatibility complex-Ⅱ(MHC-Ⅱ), CD80 and CD86 on the surface of RAW264.7 cells was detected by immunofluorescence(IF), the phagocytic function of RAW264.7 cells was examined by flow cytometry, and the levels of interleukin-6(IL-6) and nitric oxide(NO) in RAW264.7 cells in the conditioned medium(CM) co culture system of 4T1 cells were detected by enzyme-linked immunosorbent assay(ELISA) and Griess assay. ResultsAfter prophylactic administration, the tumor incidence rates in the soy isoflavone group(4%), ZGW group(4%), LWDHW group(4%), and EZW group(6%) were lower than that in the blank group(8%). Compared with the blank serum group, the drug-containing serum of the three nourishing kidney Yin formulas could enhance the expression levels of MHC-Ⅱ, CD80 and CD86 on the surface of RAW264.7 cells, enhance phagocytic ability towards tumor cells, and reduce the content of IL-6 and increase the level of NO(P<0.05, P<0.01). ConclusionThe three nourishing kidney Yin formulas can reduce the incidence of tumor in mice, the mechanism may be related to activating RAW264.7 cells, increasing their phagocytosis to breast cancer cells, and regulating the secretion of IL-6 and NO.

To introduce and analyze guideline terminology related to clinical question formulation, evidence retrieval and appraisal, and recommendation development. A systematic search was conducted in guideline development manuals and relevant methodological literature, covering publications up to October 25, 2024. Terminology related to the three aforementioned stages of related to guideline development was extracted from the included literature, standardized, and refined through consensus meetings to finalize a comprehensive terminology list and definitions. A total of 30 guideline development manuals and 15 methodological articles were included, and 23 core terms were identified. It is recommended to develop a standardized and scientifically sound guideline terminology system with unified naming, clear definitions, and alignment with the linguistic environment and usage habits in China. At the same time, it is essential to strengthen terminology training for both guideline developers and users based on this system, in order to deepen their correct understanding and proper application of guideline terminology.

The oropouche virus (OROV) poses a threat to pregnant women and fetuses, potentially causing fetal neurological defects and even stillbirth, which has caused global attention. OROV is an arthropod-borne virus belonging to the Orthobunyavirus genus in the Bunyavirales order, primarily transmitted by arthropods and causing oropouche fever. This article reviews the etiological characteristics, epidemiological distribution, clinical symptoms, detection methods, and prevention strategies of OROV. OROV is prevalent in Central and South America, with a sharp increase in cases reported in Brazil in 2024. The virus's symptoms resemble those of several other arthropod-borne viral diseases, which can lead to misdiagnosis. Currently, there are no specific drugs or vaccines available, and treatment is mainly supportive. Culicoides paraensis and Culex quinquefasciatus are among the significant vectors of OROV. Furthermore, the article analyzes the distribution of Culex quinquefasciatus in China, highlights the risk of imported cases, proposes targeted prevention and control strategies, and underscores the significance of international cooperation in disease prevention and control.
