Background and Objectives: The Fractional Flow Reserve and Intravascular UltrasoundGuided Intervention Strategy for Clinical Outcomes in Patients with Intermediate Stenosis (FLAVOUR) trial demonstrated non-inferiority of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) compared with intravascular ultrasound (IVUS)-guided PCI. We sought to investigate the cost-effectiveness of FFR-guided PCI compared to IVUS-guided PCI in Korea. Methods: A 2-part cost-effectiveness model, composed of a short-term decision tree model and a long-term Markov model, was developed for patients who underwent PCI to treat intermediate stenosis (40% to 70% stenosis by visual estimation on coronary angiography).The lifetime healthcare costs and quality-adjusted life-years (QALYs) were estimated from the healthcare system perspective. Transition probabilities were mainly referred from the FLAVOUR trial, and healthcare costs were mainly obtained through analysis of Korean National Health Insurance claims data. Health utilities were mainly obtained from the Seattle Angina Questionnaire responses of FLAVOUR trial participants mapped to EQ-5D. Results: From the Korean healthcare system perspective, the base-case analysis showed that FFR-guided PCI was 2,451 U.S. dollar lower in lifetime healthcare costs and 0.178 higher in QALYs compared to IVUS-guided PCI. FFR-guided PCI remained more likely to be cost-effective over a wide range of willingness-to-pay thresholds in the probabilistic sensitivity analysis. Conclusions Based on the results from the FLAVOUR trial, FFR-guided PCI is projected to decrease lifetime healthcare costs and increase QALYs compared with IVUS-guided PCI in intermediate coronary lesion, and it is a dominant strategy in Korea.

ObjectiveTo analyze the epidemiological characteristics of foodborne disease outbreaks in Wuhan from 2006 to 2023, and to provide a scientific basis for the development of foodborne disease prevention and control measures. MethodsDescriptive statistical analyses were performed on foodborne disease outbreaks confirmed by the district and municipal center for disease control and prevention (CDC) in Wuhan from 2006 to 2023, and the attack rate and case fatality rate were calculated as well. ResultsA total of 182 foodborne disease outbreaks were reported in Wuhan from 2006 to 2023, with a cumulative of 2 820 cases. Among which, 3 cases were dead, with an annual average attack rate of 1.22% and a case fatality rate of 0.11%. The highest number of outbreaks occurred in collective canteens (43.96%, 80/182), the highest attack rate was observed in catering facilities (11.03%), and the highest case fatality rate was found in households (1.45%). Among the foodborne disease outbreaks with identified etiologies, microbial factors were the leading causes (36.26%, 66/182), with the main pathogens being norovirus, Bacillus cereus, and other unspecified bacteria. Fungal factors were mainly attributed to poisonous mushrooms, with a relatively high fatality rate of 2.22% (2/90). Outbreaks caused by bacterial factors were more common in the central urban area (30.28%, 33/109), while fungal-related outbreaks were more frequent in the outlying urban areas (24.66%, 18/73). ConclusionCollective canteens are the main venues for foodborne disease outbreaks in Wuhan. Microbial factors are the main pathogenic factors, and poisonous mushrooms are the leading causes to death. It is necessary to strengthen the supervision on collective canteens, carry out various forms of public awareness campaigns on poisonous mushroom poisoning, and, if required, cooperate with the gardening department to eradicate wild poisonous mushrooms in the green belts. A collaborative cooperation involving multiple departments is essential to reduce the occurrence of foodborne disease outbreaks.

Mitochondrial dysfunction is a critical factor in the pathogenesis of Alzheimer's disease (AD). The mitochondrial contact site and cristae organizing system (MICOS) plays a pivotal role in shaping the inner mitochondrial membrane, forming cristae junctions and establishing interaction sites between the inner and outer mitochondrial membranes and thereby serving as a cornerstone of mitochondrial structure and function. In the past decade, MICOS abnormalities have been extensively linked to AD pathogenesis. In particular, dysregulated expression of MICOS subunits and mutations in MICOS-related genes have been identified in AD, often in association with hallmark pathological features such as amyloid-β plaque accumulation, neurofibrillary tangle formation, and neuronal apoptosis. Furthermore, MICOS subunits interact with several etiologically relevant proteins, significantly influencing AD progression. The intricate crosstalk between these proteins and MICOS subunits underscores the relevance of MICOS dysfunction in AD. Therapeutic strategies targeting MICOS subunits or their interacting proteins may offer novel approaches for AD treatment. In the present review, we introduce current understanding of MICOS structures and functions, highlight MICOS pathogenesis in AD, and summarize the available MICOS-targeting drugs potentially useful for AD.

Objective To explore the prognostic impact and clinical application value of therapeutic plasma exchange(TPE)intervention timing and liver injury periodization in patients with exertional heat stroke(EHS).Methods Data of 127 EHS patients from the First Medical Center of the General Hospital of the People′s Liberation Army from January 2011 to December 2023 were collected,then divided into the death group and the survival group based on therapeutic outcomes and into 5 stages according to the dynamic changes of ALT,AST,TBIL and DBIL.According to propensity score matching analysis,11 patients in the survival group and 12 patients in the death group were included in the statistical analysis,and 20 of them were treated with TPE.The changes in indicators and clinical outcomes before and after TPE were observed,in order to evaluate the impact of intervention timing on prognosis.Results Among the 23 patients,14 had no liver injury or could progress to the repair phase,resulting in 3 deaths(with the mortality rate of 21.43%),while 9 patients failed to pro-gress to the repair phase,resulting in 9 deaths(with the mortality rate of 100%),with significant differences(P＜0.05).The mortality rate of the first TPE intervention before the third stage of liver injury was 23.08%(3/13),while that of interven-tion after reaching or exceeding the third stage was 85.71%(6/7),and the difference was statistically significant(P＜0.05).Conclusion TPE should be executed actively in EHS patients combined with liver injury before the third phase to lock its pathological and physiological processes,thereby improving prognosis and reducing mortality.

This paper summarized the clinical experience of Professor HE Chengyao in treating recurrent miscarriage complicated with subclinical hypothyroidism. It is believed that kidney yang insufficiency is the root of the disease， while the functional decline of the five zang （脏） organs and the obstruction of the sanjiao （三焦） pivot are the key links of the pathogenesis. In clinical practice， the division of yang numbers in the Book of Changes （《周易》） is followed， and 9 months is advocated as the basic treatment cycle for recurrent miscarriage complicated with subclinical hypothyroidism. During the first half of the period before pregnancy （the first 3 months）， it is recommended to warm the pivot and sanjiao （三焦）， and Yougui Pills （右归丸） is commonly used as the basic prescription to warm and supplement the kidney yang， together with the medicinals of invigorating blood and dissolving stasis， regulating and unblocking qi movement. During the second half of the period before pregnancy （the second 3 months）， it is better to nourish essence and nature the embryo commonly with Wuzi Yanzong Pills （五子衍宗丸） in modification. After pregnancy （the third 3 months）， it is suggested to supplement kidney and consolidate chong mai （冲）， replenish qi and nourish blood mainly， supplemented by warming and nourishing heart yang， and self-made Bushen Antai Formula （补肾安胎方） which is modified based on the combination of Shoutai Pills （寿胎丸） and Wenbao Beverage （温胞饮） is commonly used.Additionally， it is recommended to adjust lifestyle and diet so as to balance yin and yang and improve the physical condition.

ObjectiveTo investigate the current situation of health communication carried out by medical institutions in Shanghai through new media platforms such as WeChat， Weibo， Toutiao， Douyin， Kuaishou， Bilibili and WeChat Videos， and to propose targeted measures. MethodsBased on the systematic collection of new media accounts of medical institutions in Shanghai， and through the combination of keyword screening and manual audit， health communication data of medical institutions on new media platforms were determined. ResultsData from 1 117 new media accounts of 162 medical institutions in Shanghai were collected， including 610 WeChat official accounts， 105 WeChat video accounts， 89 Weibo accounts， 18 Bilibili accounts， 198 Douyin accounts， 37 Toutiao accounts， and 60 Kuaishou accounts， totaling 111 853 posts. After keyword sorting and manual screening， a total of 66 761 health science posts were collected， with WeChat Official Accounts， Douyin， and Weibo having the top three highest number of posts. Video-based new media such as Douyin， WeChat Videos， Kuaishou， and Bilibili had a better communication impact than text and image-based new media like WeChat Official Accounts， Weibo， and Toutiao. Among them， Douyin and Toutiao were the best platforms for video and text-image-based new media， respectively. ConclusionMedical institutions in Shanghai recognize the importance of new media in health communication and have made full use of various media platforms to carry out health communication，having a certain impact on health education.

Background and Objectives: Angiographic assessment of coronary stenosis severity using quantitative coronary angiography (QCA) is often inconsistent with that based on fractional flow reserve (FFR) or intravascular ultrasound (IVUS). We investigated the incidence of discrepancies between QCA and FFR or IVUS, and the outcomes of FFR- and IVUS-guided strategies in discordant coronary lesions. Methods: This study was a post-hoc analysis of the FLAVOUR study. We used a QCA-derived diameter stenosis (DS) of 60% or greater, the highest tertile, to classify coronary lesions as concordant or discordant with FFR or IVUS criteria for percutaneous coronary intervention (PCI). The patient-oriented composite outcome (POCO) was defined as a composite of death, myocardial infarction, or revascularization at 24 months. Results: The discordance rate between QCA and FFR or IVUS was 30.2% (n=551). The QCAFFR discordance rate was numerically lower than the QCA-IVUS discordance rate (28.2% vs. 32.4%, p=0.050). In 200 patients with ≥60% DS, PCI was deferred according to negative FFR (n=141) and negative IVUS (n=59) (15.3% vs. 6.5%, p<0.001). The POCO incidence was comparable between the FFR- and IVUS-guided deferral strategies (5.9% vs. 3.4%, p=0.479).Conversely, 351 patients with DS <60% underwent PCI according to positive FFR (n=118) and positive IVUS (n=233) (12.8% vs. 25.9%, p<0.001). FFR- and IVUS-guided PCI did not differ in the incidence of POCO (9.5% vs. 6.5%, p=0.294). Conclusions The proportion of QCA-FFR or IVUS discordance was approximately one third for intermediate coronary lesions. FFR- or IVUS-guided strategies for these lesions were comparable with respect to POCO at 24 months.
