In the era of big data,artificial intelligence(AI)technology has developed rapidly,with medical field being one of its most deeply penetrated application domains.Leveraging the advantages of big data and AI requires the sharing and integration of medical data,yet balancing privacy protection and data sharing poses significant challenges.This paper analyzes the focus issues of patient privacy and data security in medical AI from a global perspective across 6 dimensions:challenges in data sovereignty and cross-border flow compliance,technical vulnerabilities in de-anonymization and re-identification risks,failure of informed consent mechanisms and dynamic authorization needs,regulatory gaps in algorithmic"black boxes"and data misuse,technological dependency and supply chain security risks,and the dilemma of balancing privacy protection with public health interests.Corresponding solutions and strategies are also proposed.

Objective To perform visual analysis for the literatures related to the application of new technologies in academic journal publishing,and to explore the research hotspots and development trends of new technologies applied to academic journal publishing in China.Methods We searched literatures in CNKI with the search formula SU%='Academic Journal Publishing'*('New Technology'+'5G'+'Big Data'+'Artificial Intelligence'+'Blockchain'+'Mobile Terminal'+'Cloud Computing'+'Internet'+'Database'+'VR/AR'+'Multimedia'),and using CiteSpace software,we analyzed the research hotspots and development trends of new technologies applied to academic journal publishing.Results A total of 436 articles were included in this study.The journal with the largest number of articles was China Science and Technology Journal Research.There were 34 core authors in the literatures included,and the collaboration between authors was relatively loose.The cooperation and communication between research institutions were not sufficient,and the cross-institutional cooperation needed to be strengthened.The keywords related to dimensional analysis,such as co-occurrence,clustering,and highlighting had significant characteristics.The research mainly focused on"the integrated development of academic journals and digital publishing","the innovation and development of the publishing under the background of internet+","media integration and communication strategy of academic journals","research on the application of artificial intelligence in the publishing",and"research on the communication effect of scientific and technical journals on cnki and other platforms".Conclusion The research of new technologies applied to academic journal publishing is still at a primary stage.The research mainly focuses on digital publishing,new media integration,talent training,and journal publishing reform,aiming to explore the way of talent training,academic dissemination strategy,innovative development path,and integrative development direction of academic journals in the digital era.

A novel technology is proposed for non-contact and real-time detection of atrial fibrillation using millimeter-wave radar.A 60 GHz PCR millimeter wave radar is used to continuously detect the chest echo signal of the subject.After signal acquisition,I-Q signal is generated through I-Q demodulation,and the signal phase information is extracted using effective points phase trend evaluation for obtaining the signals from oscillations in the chest wall,from which the respiratory signals and cardiac signals are extracted through digital filtering for the analysis of cardiac movement.Whether the atrial fibrillation occurs or not is determined by the characteristics of atrial fibrillation wave in the time domain.The effective points phase trend evaluation for extracting more accurate signal phase information and the time-domain method for real-time atrial fibrillation detection are the innovations of the study.The experimental results show that the proposed method achieves a detection accuracy of 99.2%in clinic.

OBJECTIVE To provide reference for Smilax glabra quality control. METHODS UPLC method was established to simultaneously determine the contents of 5-O-caffeoylshikimic acid， neoastilbin， astilbin， neoisoastilbin， isoastilbin， engelitin， resveratrol and isoengelitin in 20 batches of S. glabra from different areas （No. S1-S20）. The quality evaluation of 20 batches of samples was performed by chemometrics； the differential biomarkers that affected the quality of S. glabra were screened. RESULTS The measured 8 components had good linear relationship within the range of measured concentration （r≥0.999 6）. RSDs of precision， repeatability and stability tests （24 h） were all lower than 2.00% （n＝6）. The average recoveries varied between 97.60% and 106.40% （RSDs were all lower than 2.00%， n＝6）. Cluster analysis showed that the samples produced in Zhejiang （S1-S5） and Jiangxi （S6-S10） were clustered into one category； the samples produced in Hunan （S11-S15） were clustered into one category； the samples produced in Yunnan （S16-S20） were clustered into one category. Principal component analysis showed that the first two principal components could represent 85.60% information of 8 components in S. glabra. Partial least squares-discriminant analysis showed that variable importance projection values of 5-O-caffeoylshikimic acid， astilbin， isoastilbin and neoastilbin were all greater than 1. CONCLUSIONS There are differences in the contents of the above 8 components in S. glabra from different origins； 5-O-caffeoylshikimic acid， astilbin， isoastilbin and neoastilbin may be differential markers affecting the quality of S. glabra.

Objective:To investigate the efficacy and safety of dual antiplatelet therapy (DAPT) in patients with minor ischemic stroke (MIS) and tiny unruptured intracranial aneurysm (UIA).Methods:Patients with MIS and tiny UIA admitted to the Department of Neurology, Weifang People's Hospital from October 1, 2022 to February 29, 2024 were included retrospectively. MIS was defined as baseline National Institutes of Health Stroke Scale (NIHSS) score ≤3. Tiny UIA was defined as UIA with a diameter of ≤3 mm. According to the antiplatelet therapy regimen, the patients were divided into an aspirin alone group and an aspirin+clopidogrel DAPT group. The main outcome measure was the clinical outcome at 90 days after onset. The modified Rankin Scale (mRS) score 0-1 was defined as a good outcome and >1 was defined as a poor outcome. Secondary outcome measures included aneurysm rupture, cerebral hemorrhage, and recurrence of cerebral ischemic events. Multivariate logistic regression analysis was used to identify the independent influencing factors for poor outcome. Results:A total of 183 patients with MIS and tiny UIA were included, including 108 males (59.0%), median aged 68 years (interquartile range, 61-73 years). All the UIAs were solitary. The mRS score of all patients before onset was 0; 152 patients (83.1%) had good outcome at 90 days after onset, 31 (16.9%) had poor outcome, and no UIA occurred rupture bleeding. Of the 94 patients (51.4%) who received aspirin monotherapy, 14 patients (14.9%) experienced recurrent cerebral ischemic events during follow-up, and 73 (77.7%) had good outcome. Of the 89 patients (48.6%) who received DAPT, 5 (5.6%) experienced recurrent ischemic events during follow-up, and 79 (88.8%) had good outcome. The recurrence rate of cerebral ischemic events in the aspirin group was significantly higher than that in the DAPT group ( χ2=4.227, P=0.040), while the good outcome rate was significantly lower than that in the DAPT group ( χ2=4.006, P=0.045). Multivariate logistic regression analysis showed that baseline NIHSS score was an independent risk factor for poor outcome (odds ratio 4.597, 95% confidence interval 1.864-11.339; P=0.001), while DAPT was an independent protective factor for good outcome (odds ratio 0.265, 95% confidence interval 0.079-0.892; P=0.032). Conclusion:Compared with aspirin monotherapy, the short-term combination of aspirin and clopidogrel in patients with MIS and tiny UIA may improve the outcome, reduces the recurrence of cerebral ischemic events, and has good safety.

Ventricular remodeling after myocardial infarction leads to the occurrence and development of heart failure, and eventually leads to death. There are relatively few studies on SGLT2 inhibitors in patients with myocardial infarction. The purpose of this article is to review the research progress of SGLT2 inhibitors application before and after myocardial infarction.

Objective:To explore the influence of lateral patellofemoral joint degeneration on the treatment of anteromedial osteoarthritis of knee joint by Oxford medial unicompartmental knee arthroplasty.Methods:The clinical data of 73 patients (73 knees) with knee osteoarthritis underwent unicompartmental knee arthroplasty at Department of Orthopaedic Surgery, Xuanwu Hospital, Capital Medical University from March 2016 to December 2017 were analysed respectively.There were 18 males and 55 females, aged (68.6±7.5) years(range: 53 to 89 years).The lateral patellofemoral joints of patients were evaluated by Ahlback grading system. Patients with Ahlback 0 andⅠ were in the non degenerative group (37 cases), and those with Ahlback Ⅱ and above were in the degenerative group (36 cases). Hospital for special surgery knee score(HSS) and the Western Ontario and McMaster Universities(WOMAC) osteoarthritis index, as well as the condition of kneeling, sit to stand movement, up stair and down stair were recorded. The data before and after operation were compared by paired sample t test, and the data between groups were compared by independent sample t test. χ 2 test was used for counting data. Pearson correlation analysis was used to compare the correlation between ahlback score, HSS and WOMAC osteoarthritis index. Results:The follow-up time was (35.1±6.6) months (range: 25 to 47 months).The knee function of the patients improved significantly after operation.The HSS score increased from 57.7±11.8 preoperative to 81.8±7.8 postoperative ( t=16.64, P=0.00) and WOMAC osteoarthritis index decreased from 48.9±13.4 preoperative to 15.6±8.8 postoperative ( t=20.48, P=0.00). There was no statistical difference in the change of HSS between the degenerative group and the non-degenerative group before and after surgery(27.5±12.2 vs. 22.5±12.3, t=-1.65, P=0.10) as well as the change of WOMAC osteoarthritis index(31.8±14.0 vs. 36.4±13.7, t=-1.35, P=0.18), but the lateral patellofemoral joint degeneration was related to inability to complete squats (χ 2=5.17, P=0.04) and sitting up (χ 2=7.22, P=0.01). Conclusion:The degeneration of lateral patellofemoral joint has no effect on the early functional recovery of patients with anteromedial knee osteoarthritis after Oxford medial unicompartmental knee arthroplasty.
