Since the Asia-Pacific Association for the Study of the Liver （APASL） issued the clinical practice guidelines for metabolic associated fatty liver disease （MAFLD） in 2020， the research on MAFLD has been further deepened. Therefore， APASL has made comprehensive updates and revisions based on the previous guidelines， and the latest version of the clinical practice guidelines for diagnosis and management of MAFLD， which was released in February 2025， has updated the epidemiology， screening， assessment， and treatment of MAFLD， aiming to promote the clinical practice， knowledge popularization， and scientific research of MAFLD. This article makes an excerpt and an interpretation of the updated key points of the guidelines.

This article investigates the collaborative management of metabolic dysfunction-associated fatty liver disease （MAFLD） and chronic kidney disease （CKD）. As major public health issues worldwide， MAFLD and CKD are closely related in terms of epidemiology， pathogenesis， and management strategies， and however， there are still many challenges in the multidisciplinary collaborative management of the two diseases. This article systematically elaborates on the epidemiology of MAFLD and CKD， summarizes their common risk factors such as metabolic disorder， genetic susceptibility， and active metabolites， and reviews the mutual screening strategies and combined management models based on noninvasive imaging， serum markers， FIB-4 score， and liver stiffness measurement. In addition， this article summarizes the advances in the application of lifestyle intervention and new drugs （such as GLP-1 receptor agonists and SGLT-2 inhibitors） and emphasizes the importance of multidisciplinary collaboration in improving the prognosis of patients. Due to the close association between MAFLD and CKD， their joint management is crucial， and therefore， it is necessary to establish a multidisciplinary collaboration mechanism and implement the measures of precise screening， comprehensive treatment， and long-term monitoring， so as to improve the prognosis of patients and reduce the risk of complications. Finally， this article proposes that in the future， more effective combined treatment regimens should be explored to expand the clinical options for the co-management of the liver and the kidney.

Pneumocystis jirovecii pneumonia (PJP) is an opportunistic pulmonary infection that commonly occurs in immunocompromised children. We report a case of infantile leukemia complicated by PJP and review the relevant literature. A summary and analysis of 10 infantile leukemia patients with PJP infection (9 cases reported in the literature and 1 case from our center) showed that PJP mostly occurred in the early stages of chemotherapy (80%, 8/10). The main clinical manifestations were dyspnea (100%, 10/10) and hypoxemia (50%, 5/10), while pulmonary imaging findings lacked specificity. In most cases (50%, 5/10), diagnosis was established by identifying pathogens in bronchoalveolar lavage fluid under microscopy. In our case, diagnosis was confirmed using targeted next-generation sequencing (tNGS) of bronchoalveolar lavage fluid. Treatment with intravenous sulfamethoxazole complex was administered in 8 patients, all of whom eventually recovered. PJP may occur in the early stages of chemotherapy for infantile leukemia, thus early prevention is necessary. tNGS facilitates early diagnosis of PJP, and sulfamethoxazole complex remains an effective therapeutic option.

The endoscopic thyroidectomy by gasless unilateral axillary approach (GUA) represents a significant advancement in the field of endoscopic thyroid surgery, offering notable aesthetic and clinical therapeutic benefits. This paper reviewed the current clinical application, core technological innovations, quality control systems, and future developmental directions of GUA. Research indicated that GUA achieved surgical outcomes comparable to traditional open surgery in the treatment of benign thyroid tumors and thyroid cancer, while substantially enhancing cosmetic results and patient satisfaction. By optimizing the surgical approach design, enhancing cavity construction equipment, and standardizing the operational process, GUA markedly reduced the incidence of postoperative complications, preserved the anterior cervical functional area, and improved patients' postoperative quality of life. Furthermore, multidisciplinary collaboration and thorough pre-operative evaluation were fundamental to surgical success, while intraoperative quality control measures and a comprehensive postoperative follow-up system ensured the safety and efficacy of the procedure. In the future, the integration of robotic technology and advancements in single-site devices are anticipated to enhance the role of GUA in endoscopic thyroid surgery, thereby offering patients more minimally invasive and aesthetically favorable treatment options.

Objective To enhance the standardization of surgical operations,shorten the learning curve,and reduce surgical complications by summarizing common errors and proposing solutions for beginners during pre-study of cavity construction in non-inflatable axillary approach laparoscopic thyroid surgery.Methods A retrospective analysis was made on 210 patients who underwent noninflatable axillary approach luminal thyroid surgery at the Department of Head and Neck Surgery,Zhejiang Provincial People's Hospital,between January 2022 and June 2023.Among them,150 patients were luminalized by the practitioners in the practice group,while 60 patients were luminalized by the practitioners in the skilled group.The occurrence of nine common errors during cavity construction,such as supraclavicular nerve injury and scapulohumeral muscle injury,was assessed and compared between the two groups.Results There was no statistically significant difference in age,gender,tumor diameter,tumor location or pathology type between the two groups(P＞0.05).The staff in the practice group had a significant difference in supraclavicular cutaneous nerve injury(19.33％vs.3.33％),scapulohumeral muscle injury or disarticulation(16.00％vs.0),anterior cervical band of free excess(24.00％vs.3.33％),pectoralis major muscle and supraclavicular fascia injury(16.00％vs.5.00％),external jugular vein and genuine branch injury(8.00％vs.0),excessive freeing of the sternoclavicular joint(7.33％vs.0),and incorrect entry of the sternocleidomastoid muscle gap(8.67％vs.0)were significantly higher in incidence than the employees in the skilled group(P＜0.05).There was no statistically significant difference between employees in the practice group and those in the skilled group in terms of injury to the internal jugular vein and its geniculate branches(4.00％vs.0),and incorrect entry of the anterior cervical strap muscles into the hierarchy(2.00％vs.0)(P＞0.05).Conclusion The incidence of damage to the surrounding tissue was significantly higher in the novice group than in the expert group during endoscopic thyroid surgery for space construction.A solid anatomical foundation and proficient endoscopic surgical technique serve as fundamental prerequisites for achieving a successful space system construction.By summarizing common challenges and providing corresponding solutions encountered during endoscopic thyroid surgery,this study further enhances and refines the learning system for total endoscopic thyroid procedures.

In 2020， an international expert panel proposed to replace nonalcoholic fatty liver disease with metabolic associated fatty liver disease （MAFLD）. Recent studies have shown that there is a higher risk of chronic kidney disease （CKD） in the MAFLD population and that MAFLD is an independent risk factor for CKD. However， up to now， there are still no guidelines on the prevention and treatment of MAFLD-related CKD. Based on the Delphi method， the authors led a multidisciplinary team of 50 authoritative experts from 26 countries to reach a consensus on some open-ended research issues about the association between MAFLD and CKD， which can help to clarify the important clinical association between MAFLD and the risk of CKD and improve the understanding of the epidemiology， pathogenesis， management， and treatment of MAFLD and CKD， so as to establish a framework for the early prevention and management of these two common and interrelated diseases.

Objective:To test the feasibility, efficacy and safety of percutaneous patent foramen ovale(PFO) closure utilizing the Pansy biodegradable occluder(PBO) at 1-, 3-, 6-, 12-, 24-, and 36-month follow-up.Methods:In this single-center prospective clinical study, we enrolled 15 patients with PFO eligible for closure, all treated with the PBO, with device sizes ranging 24-34 mm. All clinical data were recorded in a 36-month follow-up period. Patients were summoned to the hospital in the 1, 3, 6, 12, 24, and 36 months after closure for transthoracic echocardiography(TTE), or transesophageal echocardiography(TEE), contrast transcranial doppler(cTCD) or contrast transthoracic echocardiography(cTTE), and a routine fasting blood sample.Results:The mean age was 27-68(44.0±16.4) years old. Indications for closure were cryptogenic stroke in 6 patients and migraine in 9 patients. Procedures were technically successful in 100%(15/15), in which course TTE showed that the position and shape of occluders were satisfactory. Small residual shunt was found by TTE in 2 patients with ASA in 1 month and 6 months after closure, respectively. 1 patient with cryptogenic stroke had another recurrent stroke 8 months after closure. At 12-month follow-up, 11 cases were closure. At 36-month follow-up, 13 cases were closure. 12 patients without atrial septal aneurysm(ASA) were closure. 1 patients with ASA was complete closure. No device-related complications occurred during the follow-up.Conclusion:PBO has good biocompatibility and suitable degradation time. A high technical success rate and closure rate can be achieved in those patients without ASA. Percutaneous closure of PFO using PBO is feasible, effective, and safe.

Metabolic associated fatty liver disease （MAFLD） is a common chronic liver disease around the world， affecting more than a quarter of the adult population worldwide. MAFLD is characterized by the co-occurrence of hepatic steatosis and metabolic disturbance. As a metabolic disorder， MAFLD shares a similar pathogenesis with cardiovascular disease （CVD）， and both diseases are closely associated with the well-established cardiovascular risk factors such as obesity， type 2 diabetes， and atherogenic dyslipidemia. An increasing amount of evidence has shown that MAFLD is closely associated with CVD； however， as a new risk factor for CVD， MAFLD differs from traditional risk factors for CVD， which requires further investigation. In this context， this consensus statement used the Delphi method to achieve a consensus on the association between MAFLD and the risk of CVD through two rounds of surveys and discussed the association between MAFLD and CVD in terms of epidemiological and clinical characteristics， as well as a range of topics including pathophysiological mechanisms， surveillance， and management.

Soft tissue defects resulting from head and neck tumor resection seriously impact the physical appearance and psychological well-being of patients. The complex curvature of the human head and neck poses a formidable challenge for maxillofacial surgeons to achieve precise aesthetic and functional restoration after surgery. To this end, a normal head and neck volunteer was selected as the subject of investigation. Employing Gaussian curvature analysis, combined with mechanical constraints and principal curvature analysis methods of soft tissue clinical treatment, a precise developable/non-developable area partition map of the head and neck surface was obtained, and a non-developable surface was constructed. Subsequently, a digital design method was proposed for the repair of head and neck soft tissue defects, and an in vitro simulated surgery experiment was conducted. Clinical verification was performed on a patient with tonsil tumor, and the results demonstrated that digital technology-designed flaps improved the accuracy and aesthetic outcome of head and neck soft tissue defect repair surgery. This study validates the feasibility of digital precision repair technology for soft tissue defects after head and neck tumor resection, which effectively assists surgeons in achieving precise flap transplantation reconstruction and improves patients' postoperative satisfaction.
