Objective:To conduct a baseline review of the best evidence for perioperative fraility management in elderly patients, construct review indicators, systematically analyze obstacle factors and promoting factors, and formulate corresponding change strategies, so as to provide reference for clinical transformation of evidence.Methods:With the Joanna Briggs Institute evidence-based health care model as the guiding framework, the best evidence of perioperative frailty-management in elderly patients was summarized, and the review indicators and review methods were formulated on the basis of the evidence. From April 2024 to May 2024, a baseline review of the hospital system of Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, medical staff and patients were conducted to analyze the obstacles in clinical practice and formulate corresponding change strategies, guided by integrated-promoting action on research implementation in health services framework(i-PARIHS).Results:According to 19 best evidence, 20 review indicators were established, among which 10 review indicators compliance rate was less than 60% and higher than 0, 2 review indicators compliance rate was 0. Based on the results of the i-PARIHS evidence-based conceptual framework analysis, the obstacle factors included the evidence content was not specific and inaccessible; lack of knowledge and skills in healthcare; the workload of medical care increased; the patient was old and had weak receptivity, lack of systematic practice process; lack of multidisciplinary communication mechanisms.Conclusions:There is a big gap between the best evidence of perioperative frailties management in elderly patients and clinical practice. Clinical departments need to deeply analyze the obstacles to clinical practice based on the existing clinical environment and resource allocation, and formulate targeted strategies to promote the better integration of evidence into clinical practice.

Objective:To design a vest-type breast dressing bra and explore its application effect in the external application of traditional Chinese medicine therapy for patients with granulomatous lobular mastitis(GLM).Methods:A randomized controlled study was conducted, utilizing convenience sampling to select female patients with 122 GLM who underwent their first topical medication treatment in the Breast Department of Guangdong Provincial Hospital of Traditional Chinese Medicine between January and May 2023. The patients were divided into a control group and an observation group, with 61 patients in each, using a random number table. Following medication application, patients in the control group used a regular sports bra to secure the medication, while patients in the observation group used a custom-designed vest-style breast medication bra for the same purpose. Three hours after the intervention, comparisons were made between the two groups in terms of the incidence of medication detachment, medication displacement, clothing contamination, patient satisfaction, and safety.Results:Both groups of patients completed the study. The age of the observation group was (32.18 ± 5.50) years old, while the age of the control group was (33.66 ± 5.20) years old. Three hours after the intervention, the incidence of medication detachment, medication displacement, clothing contamination in the observation group were 3.28% (2/61), 6.56% (4/61), and 8.20% (5/61), which were lower than those in the control group with 18.03% (11/61), 26.23% (16/61), and 67.21% (41/61), respectively. The differences were statistically significant ( χ2=6.97, 8.61, 45.23; all P<0.05). The satisfaction level of patients towards the bra in the observation group was (4.43 ± 0.85) points, higher than that of the control group (3.85 ± 1.08) points, with a statistically significant difference ( t=3.30, P<0.05). The incidence rates of skin allergic reactions were 3.28%(2/61) and 4.92%(3/61) in the observation group and the control group, respectively, with no statistically significant difference ( P>0.05). Conclusions:The vest-type breast dressing bra designed in this study can properly secure the medicinal paste, reduce the rate of medication detachment, medication displacement, clothing contamination, and enhance patient satisfaction. It facilitates the external application of traditional Chinese medicine for patients with GLM and is worthy of clinical promotion.

OBJECTIVE To establish a method for determining the content of 11 antioxidants and their degradation products in recombinant Exendin-4-FC fusion protein injection by HPLC. METHODS The protein was precipitated with saturated ammonium sulfate. After centrifugation, the supernatant was transferred to a C18 solid phase extraction cartridge activated by methanol. Then the cartridge was eluted with 4 mL of methanol and 5 mL of ethyl acetate respectively, and the eluent was diluted with methanol-ethyl acetate(2∶3) mixed solvent and passed through a 0.22 µm PTFE hydrophobic filter. It was analyzed by HPLC and quantified by external standard method. Chromatographic conditions: Kinetex® XB-C18 100Å (100 mm×4.6 mm, 2.6 µm)column, the detection wavelength was 230 nm, the column oven was 30 ℃, the injection volume was 5 µL and the flow rate was 0.4 mL·min–1, mobile phase was 0.1% formic acid-methanol(A)-0.1% formic acid aqueous solution(B), the running time was 45 min. RESULTS The 11 target substances showed a good linear relationship in the range of 2.5−35 μg·mL–1 with R2 ≥0.99. At three different concentration(25, 10, 5 μg·mL–1) of spiked samples, the average recovery rates of 11 antioxidants ranged from 88.1% to 106.5%, with RSDs in the range of 0.10%–9.05%. The RSDs of 6 repeatable samples was 2.01%–4.77%, which of 12 intermediate precision samples was 2.58%–9.75%. The positive/inverted samples of three batches of recombinant Exendin-4-FC fusion protein injection were detected at 0 month, 3 months and 6 months(25 ℃), and the results showed that there was no antioxidant and its degradation leaching in all batches of samples at different detection points. CONCLUSION The method has good specificity, high accuracy and precision, good solution stability, high durability and can be used for the content detection of antioxidants in drugs.

Objective:To establish a prediction model for symptomatic radiation pneumonitis (SRP) after radiotherapy for thoracic cancer based on a longitudinal cohort and dose interval variations.Methods:Clinical data of 587 patients who received thoracic radiotherapy in Department of Radiotherapy of Yunnan Cancer Hospital from July 2022 to June 2023 were retrospectively analyzed. The National Cancer Institute common terminology criteria for adverse events (CTCAE) version 5.0 was used to grade radiation pneumonitis, and clinical factors, traditional independent dosimetric characteristics and dose interval variation characteristics were collected. Features used to predict the occurrence of SRP were screened using genetic algorithms and analyzed the correlation between the selected features and SRP occurrence. Predictive models for SRP occurrence were established using the selected features and evaluated, and the optimal predictive model was visualized using a column chart.Results:The incidence of SRP was 35.94%. Five clinical factors, seven independent dosimetric features and six dose interval variation features were screened out by genetic algorithms to effectively predict the occurrence of SRP. The area under ROC curve (AUC) of clinical factors combined with traditional independent dosimetric factors and dose interval variation factors was 76%. The AUC of clinical factors combined with traditional independent dosimetric factors and that of clinical factors combined with dose interval variation factors was 69% and 67%, respectively. The addition of the characteristics of dose interval variation factors significantly improved the effectiveness of the prediction model.Conclusions:The supplement of the characteristics of dose interval variation factors can significantly improve the performance of the SRP prediction model for thoracic tumors after radiotherapy. The SRP prediction model based on dose interval variations can effectively predict the occurrence of SRP.
