The Proctor's reporting guideline for implementation strategies represents a landmark framework in the field of implementation science, aiming to address the issue of inconsistent reporting in implementation research by standardizing the naming, definition, and operationalization of implementation strategies, thereby enhancing the credibility and utility of research findings. This paper provides an in-depth interpretation of the core connotations of this reporting guideline and illustrates its application in developing interview outlines and specifying implementation strategies, using a brief smoking cessation intervention project as a case study. Through this reporting guideline, abstract recommendations for implementation are systematically transformed into clear, multidimensional operational guides, significantly improving the transparency of strategy connotations and the replicability of actual execution. Meanwhile, the case study highlights the flexibility of the guideline, which allows researchers to adapt the content and format of strategies based on local resources and cultural contexts, thus enhancing practical adaptability while maintaining scientific rigor. However, the application of Proctor's reporting guideline still faces challenges, primarily manifested in the potential confusion surrounding the constructs of temporality and dose in practice, as well as the challenges that the inherent flexibility of the guideline may pose to the assessment of fidelity and effectiveness. Despite these limitations, the reporting guideline remains a vital tool for implementation research; future efforts should focus on optimizing its application—through refining operational guidelines, standardizing flexible adaptations, and involving stakeholders—to better guide implementation studies and continuously promote high-quality development in the field.

Ursodeoxycholic acid (UDCA) is a naturally occurring, low-toxicity, and hydrophilic bile acid (BA) in the human body that is converted by intestinal flora using primary BA. Solute carrier family 7 member 11 (SLC7A11) functions to uptake extracellular cystine in exchange for glutamate, and is highly expressed in a variety of human cancers. Retroperitoneal liposarcoma (RLPS) refers to liposarcoma originating from the retroperitoneal area. Lipidomics analysis revealed that UDCA was one of the most significantly downregulated metabolites in sera of RLPS patients compared with healthy subjects. The augmentation of UDCA concentration (≥25 μg/mL) demonstrated a suppressive effect on the proliferation of liposarcoma cells. [¹⁵N₂]-cystine and [¹³C₅]-glutamine isotope tracing revealed that UDCA impairs cystine uptake and glutathione (GSH) synthesis. Mechanistically, UDCA binds to the cystine transporter SLC7A11 to inhibit cystine uptake and impair GSH de novo synthesis, leading to reactive oxygen species (ROS) accumulation and mitochondrial oxidative damage. Furthermore, UDCA can promote the anti-cancer effects of ferroptosis inducers (Erastin, RSL3), the murine double minute 2 (MDM2) inhibitors (Nutlin 3a, RG7112), cyclin dependent kinase 4 (CDK4) inhibitor (Abemaciclib), and glutaminase inhibitor (CB839). Together, UDCA functions as a cystine exchange factor that binds to SLC7A11 for antitumor activity, and SLC7A11 is not only a new transporter for BA but also a clinically applicable target for UDCA. More importantly, in combination with other antitumor chemotherapy or physiotherapy treatments, UDCA may provide effective and promising treatment strategies for RLPS or other types of tumors in a ROS-dependent manner.

Objective To develop a perioperative nursing protocol based on the Enhanced Recovery After Surgery(ERAS)philosophy for patients undergoing percutaneous pulmonary thrombectomy for acute pulmonary embolism(PE),and to evaluate its clinical effectiveness.Methods A convenience sampling method was employed.Thirty patients admitted to the Third Department of General Surgery at Yan'an Hospital of Kunming from May 2023 to February 2024 were enrolled as the control group and received routine perioperative care.Another 30 patients admitted from March 2024 to December 2024 were enrolled as the experimental group and were managed according to the newly developed ERAS-based nursing protocol.The differences in length of hospital stay,quality of life(QoL),complication rates,and 30-day unplanned readmission rates between the two groups were compared.Results A significant difference was observed in the total score of the Pulmonary Embolism Quality of Life(PEmbQoL)questionnaire between the experimental and control groups(t=-15.83,P<0.01).The score for the experimental group was 60.34 points lower than that of the control group,substantially exceeding the minimal clinically important difference(MCID)of 15 points.Analysis of specific dimensions showed that the experimental group had significant improvements(P<0.01)in all six areas:symptom frequency(t=-8.188),activity limitation(t=-8.722),anxiety(t=-10.31),social functioning(t=-9.118),treatment satisfaction(t=-8.202),and overall impact(t=-9.1).The length of hospital stay was significantly shorter in the experimental group(7.57±0.96 days)than in the control group(10.17±2.44 days)(t=-5.456,P<0.01).No postoperative complications occurred in the experimental group(0/30),whereas the incidence rate in the control group was 16.7%(5/30),a statistically significant difference(χ2=5.455,P<0.05).Furthermore,there were no 30-day readmissions in the experimental group(0/30),compared to a rate of 13.3%(4/30)in the control group;this difference was also statistically significant(χ2=4.286,P<0.05).Conclusion This study provides preliminary validation for the effectiveness of a multidisciplinary nursing protocol based on the ERAS philosophy for patients undergoing percutaneous pulmonary thrombectomy.

BACKGROUND:The application of miniscrew in adolescents is increasing day by day,but at present,there are few studies on bone mass in the external oblique line of the mandible in adolescents at home and abroad,and there is no systematic study on bone mass in the external oblique line of the mandible in adolescents in different growth and development periods. OBJECTIVE:To measure the bone mass in the external oblique line of the mandible in adolescents with different cervical vertebral bone ages using a cone-beam CT and to investigate the difference of bone mass in the external oblique line of the mandible in adolescents with different cervical vertebral bone ages and the correlation between bone mass in this area and the cervical vertebral bone age. METHODS:The cone-beam CT data of 105 adolescent patients before orthodontic treatment were collected and divided into CS3 group(n=24),CS4 group(n=26),CS5 group(n=29)and CS6 group(n=26)using the cervical vertebral maturation method.The adolescent mandibular buccal shelf was reconstructed by Mimics Medical 21.0 software.The width of buccal bone at 6 and 11 mm under the cemento-enamel junction and the bone height at 4 and 5 mm buccal to the cemento-enamel junction of right mandibular first and second molars were measured.The measured data were statistically analyzed.The measurement was made on four planes:plane 1 is the plane where the proximal mesial root of the mandibular right first molar is located;plane 2 is the plane where the distal mesial root of the mandibular right first molar is located;plane 3 is the plane where the proximal mesial root of the mandibular right second molar is located;and plane 4 is the plane where the distal mesial root of the mandibular right second molar is located. RESULTS AND CONCLUSION:In each group,the bone width on the buccal side of the external oblique line increased gradually from the first molar proximally to the second molar distally in adolescents,and the width of buccal bone at 6 and 11 mm under the cemento-enamel junction showed significant difference among different layers(P<0.05).The bone width of buccal bone at 11 mm under the cemento-enamel junction was greater than that at 6 mm.The bone height on the buccal side of the external oblique line increased gradually from the first molar proximally to the second molar distally in all four groups,and the bone height at 4 and 5 mm buccal to the cemento-enamel junction showed significant differences at different layers(P<0.05).The bone height at 4 mm buccal to the cemento-enamel junction was greater than that at 5 mm.On the fourth plane,the bone width at 11 mm buccal to the cemento-enamel junction was smaller in the CS3,CS4,and CS5 groups than in the CS6 group(P<0.05).On the third plane,the bone heights at 4 mm and 5 mm buccal to the cemento-enamel junction were smaller in the CS3 and CS4 groups than in the CS6 group(P<0.05).On the fourth plane,the bone height at 5 mm buccal to the cemento-enamel junction was smaller in the CS3 and CS4 groups than in the CS6 group(P<0.05).On the fourth plane,the bone height at 4 mm buccal to the cemento-enamel junction was smaller in the CS3 group than in the CS6 group(P<0.05).Spearman correlation analysis showed that there was no correlation between bone mass and the cervical vertebral bone age,except that there was a weak correlation between bone mass at some measurement sites and cervical vertebral bone age.To conclude,the bone mass in the external oblique area of the mandible in adolescents does not change significantly with the increase of cervical vertebral bone age.The buccal side of the mesial root and distal root of the mandibular second molar in the external oblique area of CS3-CS6 adolescents meets the requirement of bone mass for miniscrew implantation,which is a site available for miniscrew implantation.

BACKGROUND:Traditional lateral cephalometric radiographs always suffer from some problems,such as magnification distortion,left and right overlap inconsistency and so on,while the cone-beam CT can truly display the three-dimensional structure of the craniofacial region.Performing three-dimensional reconstruction of cone-beam CT and then transforming the cone-beam CT in the selected area into the two-dimensional image can make the overlap between the left and right sides consistent and reduce the influence of surrounding tissue structures. OBJECTIVE:To explore the consistency of quantitative analysis of cervical vertebral bone age between two kinds of cone-beam CT transformed two-dimensional images with different integrated thicknesses and traditional lateral cephalometric radiographs. METHODS:The cone-beam CT and lateral cephalometric radiograph data of 118 adolescent orthodontic patients were collected.Firstly,the cone-beam CT image was reconstructed in 3D imaging software.After reconstruction,two types of cone-beam CT images with different integrated thicknesses were selected in the sagittal interface and transformed into two-dimensional images,which were named ICB-1 and ICB-2,respectively.The Zhibeiyun system was used to measure and calculate the angle between the concave base of the second cervical vertebra and the lower edge of the vertebral body(@2),the ratio of the third cervical spine to the posterior height(AH3/PH3),the ratio of height to width of the fourth cervical spine(H4/W4)in lateral cephalometric radiograph,ICB-1,ICB-2 and the cervical vertebral bone age.After an interval of two weeks,20 adolescents were randomly selected to repeat the above measurements.The intraclass correlation coefficient(ICC)method was used to evaluate the repeatability of the three images in measuring cervical bone age.Paired t-test was used to analyze the consistency of cervical bone age measurements between the three images.The Kappa test was used to analyze the consistency of cervical vertebral bone age staging assessment between the three images. RESULTS AND CONCLUSION:(1)ICC of AH3/PH3 in the lateral cephalometric radiograph group was<0.9,and the ICC of other measurement items in each group was>0.9.(2)Paired t-test results showed that there were statistical differences in AH3/PH3 and H4/W4 between the ICB-1 group and lateral cephalometric radiograph group and between the ICB-1 group and ICB-2 group(P<0.05),and there were no statistically significant differences in the other items between the three groups(P>0.05).(3)The Kappa test results showed that the Kappa coefficients of the two groups were all more than 0.8 according to the staging of cervical vertebral bone age in three groups(P<0.001).(4)It is indicated that the repeatability of ICB-1 and ICB-2 in the measurement of cervical vertebral bone age is better than that of lateral cephalometric radiographs.Lateral cephalometric radiographs,ICB-1 and ICB-2 have good consistency in the measurement of cervical vertebral bone age,but considering the integrity of cervical vertebra structure,ICB-2 is more suitable for quantitative analysis of cervical vertebral bone age than ICB-1.

OBJECTIVE: To assess the value of using flat-sided culture tubes for preparing chromosomes through chorionic villi (CV) and amniotic fluid (AF) cell cultures during prenatal diagnosis. METHODS: From February to March 2020, 157 CV samples and 147 AF samples subjected to prenatal diagnosis at the Maternal and Child Health Care Hospital of Guangxi Zhuang Autonomous Region were selected as the study subjects. For each sample, one flat-sided tube and one flask culture were set up by following the standard protocols. The methods were evaluated by comparing the cell growth, experimental process, quality of chromosome preparation and costs. RESULTS: The success rates for the culturing of CV and AF samples by the flat-sided culture tube method were 97.45% (153/157) and 97.96% (144/147), respectively. By contrast, the success rates for the conventional flask method were 98.72% (155/157) for CV and 98.64% (145/147) for AF samples. No significant difference was found between the two methods (P > 0.05). The average harvest time required by the flat-sided culture tube method was 8.45 days for CV and 9.43 days for AF cultures, whilst the average harvest time for conventional flask method was 9.05 days and 9.54 days, respectively. The flat-sided culture tube method for CV had required significantly shorter average harvest time than the conventional method (P < 0.001). No statistical significant difference was found in the average harvest time for AF by the two methods (P > 0.05). The conventional culturing method had required three containers with two sample transfers. By contrast, the flat-sided culture tube method was carried out in one tube without any sample transfer. The average total amount of medium used was 3.91 mL for each flat-sided culture tube and 6.26 mL for each conventional flask. CONCLUSION The flat-sided culture tube method can provide a simple, cost-effective and error-reducing procedure for the CV and AF samples culture during prenatal diagnosis.

OB JECTIVE To explore the construction of system of pharmacoeconomic evaluation fo r Chinese patent medicine in preventing and treating major chronic diseases. METHODS The problems in pharmacoeconomic evaluation of Chinese patent medicine for preventing and treating major chronic diseases were analyzed. Based on the problem ，the pharmacoeconomic theory ， tools and methods that can be used to systematically evaluate the prevention and treatment of major chronic diseases by Chinese patent medicine were explored to build the relevant pharmacoeconomic evaluation system. RESULTS & CONCLUSIONS Traditional Chinese medicine shows the advantages in the prevention and treatment of major chronic diseases. This unique advantage needed to be explored ，reflected and proved in the pharmacoeconomic evaluation. The pharmacoeconomic evaluation of Chinese patent medicine had made some progress in recent years. However ，there were still deficiencies of theory and methodology in the pharmacoeconomic evaluation for the advantages of Chinese patent medicine in preventing and treating major chronic diseases. It was difficult to truly and comprehensively reflect the value of Chinese patent medicine by simply applying the economic evaluation indicators and technologies of chemical medicine. It is necessary to focus on the unique pharmacoeconomic attributes of Chinese patent medicine ，excavate the economic value indicators of Chinese patent medicine for “preventive treatment of disease ” and playing the self-regulation role of human body ，comprehensively consider the pharmacoeconomic particularity of Chinese patent medicine in respects of research design ，research angle ，target population ，intervention measures and control selection ，research time limit and evaluation method ，etc. Through the use of system modeling ，real-world research and the establishment of Chinese medicinal quality of life scale that reflects the characteristics of TCM ，the economic value of Chinese patent medicine in the prevention and treatmen t of major chronic diseases is reflected comprehensively，so as to reflect the advantage of Chinese patent medicine in preventing and treating major chronic diseases.

Objective:To explore the influence of body mass index (BMI) changes on the doses to normal tissues and adverse reactions of the lower digestive system and urinary system in the brachytherapy for cervical cancer.Methods:Clinical data of 80 cervical cancer patients who received radical radiotherapy in our hospital from January 2020 to February 2021 were retrospectively analyzed. All patients received external beam radiation ± chemotherapy + brachytherapy. The delineation method of target areas and organs at risk (OAR) was determined based on the recommended scheme of GEC-ESTRO. The target areas included high risk (HR)-CTV and intermediate risk (IR)-CTV, and OAR consisted of rectum, sigmoid colon, bladder, and small intestine. The target area dose was evaluated by D 90% of the HR-CTV. The OAR volume dose was evaluated by using D2cm3. Correlation analysis was used to compare the dosimetric relationship between BMI and D2cm3, D1cm3 and D0.1cm3 in bladder, rectum, colon and small intestine. Logistic regression analysis was adopted to analyze the risk factors of acute and late adverse reactions in the lower gastrointestinal system and urinary system. Whether BMI was a risk factor was validated. Results:BMI was negatively correlated with the D2cm3, D1cm3 and D0.1cm3 of the small intestine ( P=0.034, 0.024, 0.034), and the correlation coefficients were -0.240, -0.255, and -0.241, respectively. Logistic regression analysis showed that BMI was not a risk factor for the occurrence of acute and late adverse reactions in the lower gastrointestinal system and urinary system. For every 1 Gy increase of D2cm3, D1cm3 and D0.1cm3 in the small intestine, the relative risk of acute adverse reactions in the lower gastrointestinal system was increased by 16.6%, 15.1%,and 12.7%, respectively. Conclusions:In brachytherapy for cervical cancer, there is a negative correlation between BMI and D2cm3, D1cm3 and D0.1cm3 of the small intestine. As the BMI of patients declines, the radiation dose to the small intestine shows an increasing trend, which may increase the risk of acute adverse reactions in the lower gastrointestinal system.

Objective:To explore the related factors of nutritional status in hospitalized elders with mental disorders.Methods:A total of 584 elders with mental disorders admitted to Beijing Huilongguan Hospital from June 2020 to June 2021 were selected by convenience sampling method. General questionnaire, Barthel Index Scale, Frailty Phenotype, Mini Nutritional Assessment, Simple Physical Fitness Scale (SPFS) , Family Function Assessment Scale were collected. Univariate analysis and Pearson correlation analysis were used to analyze the related factors of patients' nutritional status. Multivariate correspondence analysis was performed for significant variables in univariate analysis.Results:The incidence of malnutrition in hospitalized elders with mental disorders was 51.88% (303/584) , and patients were divided into three groups according to nutritional status, including good nutritional status group, risk of malnutrition group, and malnutrition group for statistical analysis. Univariate analysis showed that there were significant differences in age, diagnosis, frailty, smoking, drinking, BMI, Barthel score, SPPB, family function among three groups ( P<0.01) . Correlation analysis showed that BMI ( r=0.144, P<0.01) , Barthel index ( r=0.087, P<0.05) , family social function ( r=0.257, P<0.01) and nutritional status were positively correlated with nutritional status, while age ( r=-0.252, P<0.01) , frailty ( r=-0.216, P<0.01) were negatively correlated with nutritional status. Multiple correspondence analysis showed that dementia, over 81 years old, frailty, impaired activities of daily living, and family dysfunction were the related factors of malnutrition; schizophrenia, 71-80 years old, pre-debility, good ability of daily living were the associated factors of good nutritional status; bipolar disorder, 60-70 years old were the associated factors of malnutrition. Conclusions:The health supervision and nutrition screening of hospitalized elders with mental disorders should be strengthened, and targeted nutritional intervention strategies should be adopted for patients with different mental disorders, so as to reduce the health problems.
