How to effectively promote osseointegration of dental implants remains a pressing clinical challenge. Low-intensity pulsed ultrasound (LIPUS) has demonstrated remarkable efficacy in accelerating the healing of various bodily tissues, including bone tissue. In recent years, there has been extensive research on its application in promoting osseointegration in the field of dental implantology. Animal studies have shown that LIPUS exhibits significant potential in facilitating osseointegration of dental implants. In vitro experiments have further revealed that LIPUS can enhance the expression of key osteogenic factors, extracellular matrix mineralization, and induce local neurons to secrete αCGRP. Through the regulation of signaling pathways such as bone morphogenetic protein/Smad (Bmp/Smad), mitogen-activated protein kinase (MAPK), and phosphatidylinositol 3-kinase/protein kinase B (PI3k/Akt), LIPUS promotes the proliferation, migration, and osteogenic differentiation of osteogenic-related cells, thereby enhancing osseointegration of dental implants. Additionally, clinical studies have shown that bone mass increases around the implants after LIPUS treatment, with more pronounced growth observed on the buccal bone plate than on the palatal side. Furthermore, there is a lack of research that systematically summarizes the clinical evidence, in vitro and in vivo studies, and mechanisms of action regarding the role of LIPUS in promoting osseointegration of implants. Therefore, the aim of this study is to discuss the mechanisms of effect of LIPUS on osseointegration of implants, with the goal of further enhancing the outcome of implant-supported prosthodontic treatment.
2.Four patients with hereditary angioedema with different initial symptoms and clinical features
World Journal of Emergency Medicine 2025;16(3):283-185
Hereditary angioedema (HAE) is a rare, autosomal dominant inherited disorder with an incidence of approximately 1 in 50,000. Among its various tapes, HAE with normal C1 inhibitor levels (HAE-nC1-INH) is exceptionally rare.[1] HAE symptoms include recurrent episodes of skin and mucosal edema that can occur anywhere in the body.[1-4] Laryngeal edema is life-threatening, as it can lead to airway obstruction and potentially fatal suffocation.[1-3] Edema of the gastrointestinal mucosa may cause abdominal pain, vomiting, and symptoms that are often misdiagnosed as acute abdomen.[1-4] This study included four patients, including one with HAE-nC1-INH (genetic testing revealed a heterozygous mutation in the KNG1 gene (c.1404G>C: p.Q468H)) and three with HAE due to C1 inhibitor deficiency (HAE-C1-INH). This case series aims to increase knowledge of HAE by illustrating its diverse clinical presentations and emphasizing features that may prompt clinical suspicion and facilitate timely diagnosis.

Background:
Individuals requiring liver transplantation began receiving this
procedure in Mongolia in 2011, following initial treatments abroad in 2004. As
survival rates of post-liver transplant continue to improve, it is imperative to
understand the factors influencing the quality of life for patients during these
years and to explore modifiable determinants. The interplay between socioeconomic
and environmental factors significantly impacts social and personal
development, as evidenced by quality of life metrics. Research indicates that
6% of liver transplant recipients are classified as unable to work based on activity
and international disability assessments, while 23% to 61% of recipients
achieve full employment following liver transplantation treatment. However,
there is a notable lack of studies examining the physical, psychological, and
social well-being of patients post-liver transplant in Mongolia. This study aims
to address this gap and provide insights into the overall health status of these
individuals.
Aim:
Examining quality of life and employment status following liver transplantation
treatment
Materials and Methods:
A descriptive study design and questionnaire method
were used to collect data from 144 cases of individuals who underwent liver
transplantation. The study was based on the SF-36 Health Survey, categorized
into eight domains, with scores calculated according to predefined criteria.
Results:
Among the 144 cases included in the study, 81 (56.3%) were male
and 63 (43.8%) were female. By age group, 120 (83.3%) were between 19
and 60 years old, representing the working-age population, while 24 (16.7%)
were over 60 years old. Post-liver transplant employment status revealed
significant differences, with 41 (28.5%) employed full-time, 19 (13.2%) parttime,
and 84 (58.3%) unemployed or receiving disability benefits (p=0.024).
Among these, 62 (43%) expressed a desire to work, 17 (12%) did not wish to
work, and 65 (45%) were uncertain, showing no statistically significant differences
(p=0.173). When calculating the quality of life assessment, the physical
function index was 63.52±25.32 for working patients and 52.90±25.75
for non-working patients (p=0.018), and the psychological status index was
64.94±14.53 for working patients and 53.63±17.87 for non-working patients
(p<0.001), and there was a statistically significant difference.
Conclusion
Health-related quality of life in people who are employed after
liver transplantation is high, and overall physical function and overall psychological
well-being improve year after year.

Autologous blood patch pleurodesis (ABPP) was first proposed in 1987. Now it is mainly used to treat intractable pneumothorax and persistent air leakage after pneumonectomy, and also used to treat pneumothorax in children and other rare secondary pneumothorax. Persistent air leakage and pneumothorax of various causes are essentially alveolar pleural fistula. It can usually be treated by closed thoracic drainage, continuous negative pressure suction and surgery. Pleurodesis is a safe and effective alternative to surgery for patients who have failed conventional conservative treatment and can not receive operations. Compared with other pleurodesis adhesives, autologous blood (ABPP) is safer and more effective, and it is simple, painless, cheap and easy to be accepted by patients. But in the domestic and foreign researches in recent years, many details of ABPP treatment have not been standardized. For further research and popularization of ABPP, this article reviews the detailed regulations, efficacy and safety of this technology.

In the field of oral medicine, 3D-printed individualized titanium mesh technology is gradually becoming an important means for the treatment of severe alveolar bone defect augmentation. This article provides a comprehensive analysis of the advantages of this technology, the evaluation of osteogenic effects, and the progress of research in clinical applications. In response to the current issue of variability in bone augmentation outcomes, this paper delves into multiple factors affecting bone augmentation effects, including individualized titanium mesh design (involving the thickness, pore size, pore shape, porosity, contour shape, selection of titanium alloy materials, and 3D printing technology), intraoperative procedures (the accuracy of placement during 3D-printed individualized titanium mesh surgery), and postoperative care (including the prevention of complications, formation of pseudoperiosteum, and stability of the titanium mesh). By integrating the clinical experience and research findings of our team, we propose a series of targeted optimization strategies, including designing, manufacturing, and clinically applying self-positioning individualized titanium meshs (positioning wings + individualized titanium meshs) to improve the positioning accuracy of the titanium mesh; propose individualized treatment processes and titanium mesh design schemes based on specific conditions of alveolar bone defects and soft tissue status; and emphasize the importance of long-term stable fixation of the titanium mesh to reduce the risk of postoperative mesh loosening and displacement. In addition, we appropriately summarize the evaluation methods for the bone augmentation effects of 3D-printed individualized titanium meshes, covering the following key indicators: (1) vertical bone augmentation and horizontal bone augmentation; (2) changes in bone contour morphology; (3) bone volume increase; (4) clinical indicators (surgical success rate, titanium mesh exposure, infection rate, and postoperative recovery); (5) aesthetic effect evaluation; (6) long-term stability; (7) radiological assessment; (8) patient satisfaction; and (9) precision of surgical operation, aiming to assist doctors in comprehensively assessing and in-depth analyzing the surgical outcomes to achieve the best therapeutic effects. The purpose of this article is to provide a reference for the optimization and clinical application of 3D-printed individualized titanium mesh technology and to lay a theoretical foundation for achieving the best osteogenic effects.
8.Immunotherapy for small cell lung cancer: progresses and challenges
Chinese Journal of Cancer Biotherapy 2025;32(1):14-23
[摘 要] 小细胞肺癌(SCLC)是肺癌中恶性程度最高的一种类型,其在全部肺癌病例中约占13%~15%。初治SCLC患者虽然对化疗和放疗具有较高的敏感性,但容易复发,导致患者生存率较低。2018年以来,随着IMpower133和CASPIAN研究相继成功,SCLC进入了免疫治疗时代,化疗联合免疫检查点抑制剂已成为广泛期SCLC的一线治疗标准方案。同时,免疫治疗在局限期SCLC中也取得了初步成功。SCLC的免疫治疗虽然取得了一些进展,但免疫治疗整体上带来的生存获益有限,缺乏有效的预测生物标志物,对复发/难治性SCLC缺少治疗手段,SCLC免疫治疗未来仍面临诸多挑战。本文回顾国内外SCLC免疫治疗临床研究的最新进展,分析不同类型的免疫治疗药物、生物标志物及新型免疫治疗靶点,探讨SCLC免疫治疗的联合策略和发展前景。
9.Pediatric bronchial rupture: outcomes in four cases
World Journal of Emergency Medicine 2025;16(1):85-87
Bronchial rupture from penetrating, perforating, or compressive cervical or thoracic injuries can lead to complete tracheal, mainstem bronchial, or lobar bronchial detachment. Although rare in children, bronchial rupture presents significant risks, including dyspnea, respiratory failure, and potentially fatal airway obstruction, and is often overlooked or diagnosed late in clinical settings. Prompt diagnosis and intervention are prognostically crucial.[1,2] Between January 2013 and December 2023, four children (two male and two female) with bronchial rupture were admitted to the Pediatric Surgical Intensive Care Unit (ICU) at Children’s Hospital, Zhejiang University School of Medicine. Here, we share our experience of patient management.
10.Pneumonia caused by co-infection with Pneumocystis jirovecii and Trichosporon coremiiforme
World Journal of Emergency Medicine 2025;16(1):99-100
Fungal infections are relatively common among patients with systemic lupus erythematosus (SLE), and patients may be infected simultaneously or sequentially with multiple fungal species. Physicians need to select appropriate antifungal agents and therapeutic regimens based on the type and severity of the infection. Herein, we report a young SLE patient who developed concurrent pulmonary infection with Pneumocystis jirovecii and Trichosporon coremiiforme. The patient presented with a variety of imaging manifestations, with specific features evolving as the disease progressed.
