In recent years, with the continuous development and increasing maturity of interventional techniques, interventional treatment for congenital heart disease (CHD) has been progressively disseminated to county- and city-level hospitals in China. Concurrently, the standardized management of adult CHD (particularly patent foramen ovale) and the lifelong management of complex CHD are gaining increasing clinical attention, while the emergence of new techniques and products continuously advances the discipline. This article aims to review the new progress made in the field of interventional treatment for congenital heart disease in China during 2024. It specifically reviews and analyzes the following key aspects: (1) annual statistics on interventional closure procedures for CHD; (2) recent insights into patent foramen ovale closure; (3) advances in transcatheter pulmonary valve replacement; (4) interventional treatment and lifelong management strategies for complex CHD; (5) new interventional techniques for acquired heart disease; and (6) the application of artificial intelligence in CHD management. Through the synthesis and discussion of these topics, this article seeks to provide a detailed analysis of the current landscape of interventional treatment for CHD in China and project its future development trends.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

This article reports a first case of combined infection with severe fever with thrombocytopenia syndrome(SFTS)and scrub typhus in Dalian City.The patient was admitted to the hospital due to recurrent fever for 7 days and loss of consciousness for 1 day.Pathogen metagenomic sequencing(mNGS),SFTSV quantitative PCR,and enzyme-linked immunosorbent assay(ELISA)IgM tests were performed,showing positive results for Orientia tsutsugamushi and SFTSV nucleic acids.Based on clinical manifestations and epidemiological history,the patient was diagnosed with combined infections.

Objective To investigate the molecular mechanism by which long non-coding RNA(lncRNA)titin antisense RNA 1(TTN-AS1)regulates the microRNA(miR)-134-5p/epidermal growth factor receptor(EGFR)axis in breast cancer cell proliferation,apoptosis and glycolysis.Methods Western blot was used to detect EGFR protein expression.Quantitative real-time poly-merase chain reaction(qRT-PCR)was employed to measure the expression levels of lncRNA TTN-AS1,miR-134-5p and EGFR mRNA in breast epithelial cells MCF-10A and breast cancer cell lines MCF-7,MDA-MB-231 and SKBR-3.MDA-MB-231 cells were selected for subsequent experi-ments,and were divided into control,si-lncRNA TTN-AS1,si-lncRNA TTN-AS1+miR-134-5p-in-hibitor and si-lncRNA TTN-AS1+EGFR-mimic groups.Cell proliferation rates were determined u-sing the CCK-8 assay.Apoptosis rates were assessed by flow cytometry.Lactic acid,glucose and a-denosine triphosphate(ATP)kits were used to detect glucose intake,lactic acid and ATP produc-tion in each group,respectively.Dual-luciferase reporter assays were performed to identify the bind-ing sites between lncRNA TTN-AS1 and miR-134-5p,as well as between miR-134-5p and EGFR.Results Compared with MCF-10A cells,the expression levels of lncRNA TTN-AS1 and EGFR mR-NA were significantly higher,while miR-134-5p expression was significantly lower in breast cancer cell lines(P＜0.05).Among these,MDA-MB-231 cells exhibited the highest expression levels of lncRNA TTN-AS1 and EGFR mRNA,and the lowest expression level of miR-134-5p(P＜0.05).Compared with the control group,the expression level of miR-134-5p was significantly increased,while the expression levels of lncRNA TTN-AS1,EGFR mRNA,and EGFR protein were significant-ly decreased in the si-lncRNA TTN-AS1 group(P＜0.05).Compared with the si-lncRNA TTN-AS1 group,the expression levels of EGFR mRNA and EGFR protein were significantly increased,and miR-134-5p expression was significantly decreased in the si-lncRNA TTN-AS1+miR-134-5p-inhibitor group and si-lncRNA TTN-AS1+EGFR-mimic group(P＜0.05).Compared with the con-trol group,cell proliferation rates were significantly reduced in the si-lncRNA TTN-AS1 group(P＜0.05).Compared with the si-lncRNA TTN-AS1 group,cell proliferation rates were significantly in-creased in the si-lncRNA TTN-AS1+miR-134-5p-inhibitor group and si-lncRNA TTN-AS1+EGFR-mimic group(P＜0.05).Compared with the control group,apoptosis rates were significantly in-creased in the si-lncRNA TTN-AS1 group(P＜0.05).Compared with the si-lncRNA TTN-AS1 group,apoptosis rates were significantly reduced in the si-lncRNA TTN-AS1+miR-134-5p-inhibitor group and si-lncRNA TTN-AS1+EGFR-mimic group(P＜0.05).Compared with the control group,glucose uptake,lactate production and ATP generation were significantly decreased in the si-lncRNA TTN-AS1 group(P＜0.05).Compared with the si-lncRNA TTN-AS1 group,glucose up-take,lactate production and ATP generation were significantly increased in the si-lncRNA TTN-AS1+miR-134-5p-inhibitor group and si-lncRNA TTN-AS1+EGFR-mimic group(P＜0.05).The du-al-luciferase reporter assay confirmed that lncRNA TTN-AS1 had a targeted binding site with miR-134-5p,and miR-134-5p has a targeted binding site with EGFR.Conclusion The lncRNA TTN-AS1 may negatively regulate the miR-134-5p/EGFR axis,thereby affecting the proliferation,apop-tosis and glycolysis of breast cancer.

China has become the country with the highest global burden of heart failure(HF).Despite the widespread use of prognostic-improving medications today,the mortality rate of HF remains high,reaching 13.7％at one year-particularly among patients with heart failure with reduced ejection fraction(HFrEF).HF interventional device therapy(structural intervention)targets the structural factors underlying HF,including atrial pressure,ventricular remodeling,and valvular intervention.It leverages the heart's intrinsic physiological properties and pathological progression mechanisms to deliver treatments through interventions without external active forces,achieving anatomical or functional repair.This field has emerged as a rapidly growing area and plays an increasingly critical role in HF management.This article provides a comprehensive review and summary of the latest advancements in HF and cardiomyopathy interventional therapy over the past year.It covers various novel technologies and products currently in the research phase,aiming to provide an in-depth analysis of the current status and future directions of HF interventional therapy,and further advance the development of this discipline.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

Oligoasthenozoospermia(OAS)is one of the most common types of male infertility,which,however,still lacks ef-fective treatment.An increasing number of studies have shown the potential therapeutic value of omega-3 polyunsaturated fatty acid(ω-3 PUFA)in the treatment of OAS.This article presents an overview of the studies on the effects of ω-3 PUFA on fatty acid composition and metabolism,inflammatory response,and oxidative stress in OAS,hoping to provide some new ideas for the treatment of the dis-ease.
