Objective: To analyze the institutional and regional differences in influenza vaccination for teachers and students, so as to provide a basis for influenza prevention and control in campus. Methods: Influenza vaccination data for teachers and students in Shandong Province from 2015 to 2024 were collected from Immunization Information Systems. Joinpoint regression models were used to calculate the annual percent change (APC) and average annual percent change (AAPC) in first-dose vaccination rates. Results: The vaccination coverages for the first dose of influenza vaccine among teachers in Shandong Province from 2015 to 2024 were 0.01%, 0.02%, 0.15%, 0.29%, 0.60%, 2.06%, 1.64%, 2.27%, 3.00%, and 2.43%, with a turning point in 2020. For preschools, primary/secondary schools, and higher education institutions, APCs during 2015-2020 were 163.36%, 162.09%, and 174.94%, respectively( P <0.01), declining to 9.53%, 9.92%, and 8.14% during 2020-2024( P >0.05). Corresponding AAPCs were 78.32%, 78.13%, and 81.61%( P <0.01). High, middle, and low GDP regions exhibited APCs of 173.84%, 162.75%, and 136.67% during 2015-2020( P <0.01) and 5.77%, 13.92%, and 11.86% during 2020-2024( P >0.05), with AAPCs of 79.42%, 81.23% , and 69.63%( P <0.01), respectively. Among students, vaccination coverage ranged from 1.59% to 7.20%. Preschool students showed no turning points, with an AAPC of 18.73%( P <0.01). Primary/secondary students had turning points in 2018 and 2022, APCs were -32.59% during 2015-2018( P <0.01), 48.45% during 2018-2022( P <0.01), and -26.25% during 2022-2024( P =0.04), yielding an AAPC of -2.32%( P =0.45). Higher education students had a turning point in 2020, with APCs of 63.27% during 2015-2020( P <0.01) and 4.31% during 2020-2024 ( P =0.77), and the AAPC was 33.79% during 2015-2024 ( P <0.01). High, middle, and low GDP regions for students showed no turning points, with AAPCs of 10.46%( P =0.18), 13.67%( P =0.01), and 10.42%( P = 0.05 ), respectively. Conclusions The influenza vaccination rate among teachers and students in Shandong Province has shown an upward trend from 2015 to 2024, but the overall level is still relatively low. However, continued efforts are needed to enhance health education on influenza and vaccination, to further improve the vaccination rate of teachers and students.

It has been proposed by Basic Questions On Proper Therapies for Different Diseases Geographically （《素问·异法方宜论篇》） that "wei （痿） diseases should be treated by Daoyin （导引）". Furthermore， it is clarified that the indications of Daoyin are those conditions related to spleen and dampness caused by dampness pathogen， excessive food intake and less exercise， and mainly manifested as heavy limbs， fatigue and flaccidity， which is similar to the metabolic imbalance in the early stage of glucose or lipid metabolism disorder in modern medicine. Based on modern clinical and basic research evidence， Daoyin can inhibit the response of inflammation， alleviate oxidative stress， regulate intestinal microbiota， and modulate gene expression to improve metabolic abnormalities， and this will provide ideas for researches on the indications of Daoyin.

ObjectiveTo investigate the current status and development needs of evidence-based medicine （EBM） capability in ethnic minority medicine， and explore effective strategies to enhance EBM capability in this field. MethodsThe questionnaire survey was conducted in various ethnic minority medical institutions and research organisations. The questionnaire covered three dimensions， firstly， perceptions and attitudes towards evidence-based medicine； secondly， advantages and challenges in the development of ethnic minority medicine； thirdly， demands and recommendations for enhancing evidence-based medicine capability in ethnic minority medicine. ResultsA total of 501 valid questionnaires were collected， of which 103 questionnaires were collected by re-sending to minority medicine regions with insufficient participation. The questionnaires included 354 responses （70.66%） from practitioners of minority medicine， including Tibetan medicine， Mongolian medicine， Uyghur medicine， Zhuang medicine， and Korean medicine. Among the 501 questionnaires， 146 respondents （29.14%） indicated that they knew about EBM， 355 respondents （70.86%） had either a "general understanding" or had "not heard about" EBM before， and 469 respondents （93.61%） believed that introducing ECM could promote the development of ethnic minority medicine. The primary challenge in promoting EBM in the field of ethnic minority medicine is the lack of professionals in EBM and a lack of understanding of how to apply it into clinical practice （442 respondents， 88.22%）. In the 9-point importance rating for enhancing evidence-based abilities， high scores were achieved in standardization of clinical practice guidelines （7.50±1.90） and methods for sample sizes in clinical research （7.45±1.90）. Regarding the demand for improving clinical research literacy， expert academic lectures， and experience sharing （404 respondents， 80.64%） and evidence-based methodology monographs on ethnic minority medicine （401 respondents， 80.04%） were emphasized. ConclusionsPractitioners in ethnic minority medicine hold a positive attitude towards integrating EBM. However， there remains substantial room for the education and dissemination of EBM. Enhancing evidence-based capabilities can be achieved through specific measures such as cultivating or recruiting talents in EBM， establishing evidence-based support platforms for clinical research， organizing regular academic lectures and exchanges， and strengthening the construction of theoretical frameworks and evaluation systems tailored to ethnic minority medicine， thereby following a path of evidence-based practices aligned with the unique characteristics of ethnic minority medicine.

Objective:To evaluate the diagnostic efficacy of the novel prostate specific membrane antigen (PSMA)-targeted PET imaging agent 18F-AlF-P16-093 in combination with multiparametric MRI (mpMRI) for prostate cancer (PCa), and to explore its application in guiding transperineal puncture biopsy. Methods:A retrospective analysis was conducted on the clinical and pathological data of 36 patients diagnosed as PCa (age: 68-76 years) who underwent 18F-AlF-P16-093 PET/CT and mpMRI examinations at the First Affiliated Hospital of Guangzhou Medical University from August 2023 to March 2024. The entire prostate was divided into 12 regions based on biopsy localization. Imaging evaluations were performed using PET/CT and mpMRI at the lesion level, with biopsy pathology as the gold standard. The correlations between mpMRI scores, PET/CT scores and pathological diagnosis results were evaluated by Phi coefficient analysis. Diagnostic efficacy was assessed by ROC curve analysis. Logistic regression was used to determine the impact of bleeding on image interpretation. Results:18F-AlF-P16-093 PET/CT showed a moderate positive correlation with pathological diagnosis result ( Phi=0.415, P<0.001), which was superior to mpMRI ( Phi=0.338, P<0.001). The diagnostic efficacy of PET single-modality model was superior to mpMRI in all indicators. The combination of 18F-AlF-P16-093 PET/CT with mpMRI significantly improved diagnostic specificity and positive predictive value, with the diagnostic specificity of the PET+ T 2 weighted imaging (WI)+ diffusion WI (DWI) and PET+ T 2WI+ DWI+ apparent diffusion coefficient (ADC) combinations exceeding 90%, and the positive predictive value exceeding 80%. Bleeding did not significantly affect the diagnosis of PCa by mpMRI and PET/CT (odds ratio ( OR): 0.463-0.785, all P>0.05). Conclusion:18F-AlF-P16-093 PET/CT is superior to mpMRI in the detection and diagnostic efficacy of PCa lesions, and the combination of 18F-AlF-P16-093 PET with mpMRI can further improve diagnostic specificity and positive predictive value, which is of guiding significance for targeted prostate biopsy.

OBJECTIVE: To investigate the effectiveness of distal radius core decompression in the treatment of chronic wrist pain caused by various etiologies. METHODS: A retrospective analysis was performed for the clinical data of 10 patients with chronic wrist pain treated with distal radial core decompression between January 2018 and December 2021. There were 6 males and 4 females with an average age of 37.4 years (range, 21-55 years). The disease duration ranged from 7 to 72 months, with an average of 26.5 months. Preoperative MRI examination showed that 10 cases had bone marrow edema at the distal radius on the affected side, and 8 cases had bone marrow edema in the carpal bones such as scaphoid and lunate bone. Among them, 3 patients had a history of wrist fracture, and 2 patients had Kienböck diseases (1 case each in stage ⅡB and stage ⅢA). Three cases were combined with triangular fibrocartilage complex (TFCC) type 1A injury. Two cases were combined with osteoarthritis, 1 of them was complicated with severe traumatic arthritis, the wrist arthroscopy showed that the TFCC was completely lost and could not be repaired, and the cartilage of the lunate bone and the ulnar head were severely worn.Visual analogue scale (VAS) score was used to evaluate the relief of wrist pain before operation, at 6 months after operation, and at last follow-up, and the range of motion of the affected wrist in dorsiflexion, palmar flexion, ulnar deviation, and radial deviation was measured. The degree of bone marrow edema was evaluated according to T1WI, T2WI, and STIR sequences of MRI. RESULTS: All the patients were followed up 12-22 months, with an average of 16.4 months. Except for 1 patient who experienced persistent wrist joint pain and limited mobility after operation, the remaining 9 patients showed significant improvement in pain symptoms and wrist joint mobility. The VAS score and range of motion of wrist dorsiflexion, palmar flexion, ulnar deviation, and radial deviation at 6 months after operation and at last follow-up were significantly improved when compared with those before operation, the VAS score and the range of motion of wrist ulnar deviation and radial deviation at last follow-up were further improved when compared with those at 6 months after operation, all showing significant differences ( P<0.05). There was no significant difference in wrist dorsiflexion and palmar flexion between at 6 months after operation and at last follow-up ( P>0.05). Bone marrow edema was improved in 6 patients on MRI at 6 months after operation, and was also improved in other patients at last follow-up. CONCLUSION For chronic wrist pain caused by a variety of causes, distal radius core decompression can directly reduce the pressure of the medullary cavity of the distal radius, improve the blood supply of the corresponding distal structure, significantly alleviate chronic wrist pain, and provide an option for clinical treatment.

The grading of evidence is an important factor in clinical decision-making. The current evidence grading system based on western medicine is limited in the clinical practice of traditional Chinese medicine （TCM）， therefore we propose the solutions to the development of grading system for TCM interventional evidence， following the international evidence grading standards， taking into considerations of the unique characteristics of TCM practice， based on the Grades of recommendation， assessment， development and evaluation （GARDE） evaluation system， and integrating with grading system regarding TCM classical literature and empirical evidence from modern famous doctors. The evidence from classical literature is suggested to be evaluated from three aspects including source of ancient medical records， comprehensive of treatment details， and the inheritance. The qualification of famous doctors， content integrity， and inheritance of experiences will be used to evaluate the evidence from famous doctors' experience. The multi-sourced evidence such as TCM classical literature， experience of modern famous doctors， and modern researches is mainly integrated in a qualitative way， and the overall level of evidence of TCM interventions will be graded consistently with the GRADE system based on modern research. The evidence from classical literature and modern famous doctors' experience will be assessed and considered as supplementary evidence， which will make the evaluation of clinical evidence more objectively and comprehensively， thereby guiding clinical practice further.

Objective: To evaluate and compare a series of volume changes in the nasal cavity (NC), nasopharynx, oropharynx, and maxillary sinuses (MS) in growing Class III patients after either rapid palatal expansion (RPE) or alternate rapid maxillary expansion and constriction (Alt-RAMEC) followed by facemask (FM) therapy, by using conebeam computed tomography (CBCT). Methods: Forty growing Class III patients were retrospectively selected and divided into two matched groups: RPE/FM (14 females, 6 males; mean age, 9.66 ± 1.23 years) and Alt-RAMEC/FM groups (14 females, 6 males; mean age, 10.28 ± 1.45 years). The anteroposterior and vertical displacements of Point A, the volumes of the NC, nasopharyngeal, oropharyngeal, and MS were measured at different time points: pretreatment (T1), postexpansion (T2), and postprotraction (T3). Results: Both groups demonstrated significant maxilla advancement (by 1.3 mm) during expansion, with a statistically significant intergroup difference during protraction (RPE/FM, 1.1 mm; Alt-RAMEC/FM, 2.4 mm; p < 0.05) and throughout the treatment (RPE/FM, 2.4 mm; Alt-RAMEC/FM, 3.7 mm; p < 0.05). NC and nasopharyngeal airway volumes increased significantly in both groups after expansion, protraction, and treatment. The oropharyngeal and MS volumes increased in both groups after protraction and post-treatment. However, no volumetric differences were observed between the two groups. Conclusions There was no significant difference in airway volume changes, including NC, nasopharyngeal, oropharyngeal airway, and MS, between RPE/FM and Alt-RAMEC/FM groups at different time points. Although there was significantly more forward movement after protraction in the Alt-RAMEC/FM group, the difference was deemed too small to be clinically relevant.

Objective:To investigate the relationship between sleep quality and slow-flow in patients with acute coronary syndrome during percutaneous coronary intervention(PCI) and its impact on clinical prognosis.Methods:200 patients with ACS hospitalized in the cardiology department of Guangzhou First People's Hospital from January 2017 to October 2018 were selected. The Pittsburgh Sleep Quality Index (PSQI) was measured before elective PCI, and the sleep breathing of patients was monitored by micro motion sensitive mattress sleep monitoring system (MSMSMS). The patients were divided into normal sleep group (68 cases, PSQI≤7 points) and sleep disorder group (132 cases, PSQI>7 points). The levels of plasma endothelin-1 (ET-1) and nitric oxide (NO) were measured. The " slow-flow" that took place during PCI were also recorded. Major cardiac adverse events (MACE) of patients took placed during 12 months follow-up periods were recorded and compared between two groups.Results:Compared with normal sleep group, patients in sleep disorder group had higher ratio of sleep apnea-hypopnea syndrome (SAHS), hypoxemia and lower deep sleep (25.00% vs 10.29%, 25.76% vs 11.76%, 66.67% vs 48.53%, all P<0.05); lower level of NO and higher level of ET-1 [(28.65±3.26)μmol/L vs (30.24±4.08)μmol/L; (21.17±3.08)pg/ml vs (18.90±2.95)pg/ml, P<0.05]; more slow-flow events took place during PCI in sleep disorder group than normal sleep group (16.67 vs 5.88%, P<0.05); After 12 months of follow-up, Kaplan-Meier survival analysis showed patients of the two groups had significantly different cumulative non-events survival rates (19.70% vs 7.35%, Log rank=5.06, P=0.025). Conclusions:Sleep disorder increase the slow-flow phenomenon during PCI in patients with ACS and affect the clinical prognosis.

Objective:To investigate the effects of applying Stent Boost Subtract (SBS) technique during percutaneous coronary intervention in patients with complex coronary lesions.Methods:200 patients with coronary artery disease (CAD) who hospitalized in the department of cardiology in Guangzhou First People′s Hospital from June 2018 to June 2020 were enrolled. The coronary lesions of all patients were corresponding to B2 or C type suggested by American Heart Association (AHA)/American College of Cardiology (ACC) according to coronary angiography and treated with percutaneous coronary intervention (PCI). Patients were randomly divided into SBS group ( n=82, SBS technique was applied during PCI) and IVUS group [ n=118, intravascular ultrasound (IVUS) was applied during PCI]. After stent implantation, quantitative coronary angiography (QCA) automatic analysis system was used to measure the related parameters of stent diameter (including the minimum, maximum and mean value of stent diameter) and calculate the stent eccentricity index. During PCI, stent eccentricity index, post-stent expansion, poorly positioned stent with open lesions, failure of overlapping stent with long lesions, mean cumulative dose (CD), product of total dose area (DAP), X-ray time, operation time and operation cost of each PCI were recorded in the two groups. Patients were followed up for 18 months after PCI, and the occurrence of adverse cardiovascular events (MACE) was recorded during the follow-up period, and the cumulative survival rate without MACE was compared between the two groups. Results:There were no statistically significant differences between the two groups in stent eccentricity index, proportion of guided stent expansion, proportion of poorly positioned stent with open lesions, proportion of stent failure to overlap, with statistically significant difference[(0.12±0.04) vs (0.10±0.03); 80.49% vs 85.49%; 2.44% vs 2.54%; 1.22% vs 2.54%, all P>0.05]. There were no significant differences in CD, X-ray time and DAP in SBS group compared with IVUS group [(1 394.18±42.29)Gy/cm 2 vs (1 391.82±45.06)Gy/cm 2; (18.79±3.01)min vs (18.95±3.12)min, (100.24±5.70)Gy/cm 2 vs (99.47±5.93)Gy/cm 2; all P>0.05]. The operation time in SBS group was shorter than that in IVUS group [(70.91±6.51)min vs (73.89±8.95)min, P<0.05], and the operation cost was less than that in IVUS group [(2.98±0.86)ten thousand yuan vs (3.85±0.81)ten thousand yuan, P<0.05]. After 18 months of follow-up after PCI, Kaplan-Meier survival analysis showed that there was no significant difference in MACE event-free survival between SBS group and IVUS group (91.46% vs 94.07%, Log Rank=0.480, P=0.489). Conclusions:SBS is a kind of convenient and effective technique in guiding PCI in patients with complex coronary lesions without increasing operation time and radiation dose, which can achieve the same effect as IVUS guidance.

Objective Investigation of the significance for applying the percentage of neutrophils, neutrophil to lymphocyte ratio combined with contrast enhanced ultrasonography in the diagnose of coronary artery disease through examining the percentage of neutrophils, neutrophil to lymphocyte ratio on peripheral blood. Methods 130 patients with acute coronary syndrome (ACS group) , 90 patients with stable angina (SAP group) and 50 nonCAD patients (control group were observed. The neutrophils counts of all the patients were detected and Neut％, NLR were calculated; all the patients were asked to examine enhanced carotid contrast echocardiography. The plaque enhancement (DE) , and luminal enhancement ratio (Ratio) were recorded. The differences in neut％, NLR and CEUS were compared among the three groups. The Pearson correlation analysis was used to analyze the correlation between Ratio and Neut％, NLR. Multivariate logistic regression analysis was used to evaluate the predictive value of Neut％, NLR and CEUS for ACS. Results (1) The value of Neut％, NLR of the peripheral blood, DE, and Ratio in both ACS group and SAP group were higher than those in control group, and the value of ACS group was higher than that in SAP group (P < 0.05 or P < 0.01); (2) The analysis of Linear correlation showed that the ratio of CEUS in ACS patients was positively correlated with Neut％ (r = 0.422, P = 0.001) and NLR (r = 0.407, P = 0.001). (3) The ROC results showed that circulating Neut％, NLR and DE, Ratio play a significant role in the diagnose of unstable plague in CAD patients; (4) Multivariate logistic regression analysis showed that Neut％, NLR, DE, Ratio were independent indicators of the ACS patients (P< 0.05 or P < 0.01).Conclusions Contrast enhanced carotid examination combined with leukocyte analysis on peripheral blood were useful to detect plaque instability and inflammatory response in CAD patients, and it also provide lots of objective evidence for predicting and intervening unstable plaque in CAD patients.
