Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. It has a high prevalence and poor prognosis. The application of antiarrhythmic drugs and even surgery cannot completely treat the disease, and there are many sequelae. AF can be classified into the category of "palpitation" in Chinese medicine according to its symptoms. Acupuncture has a significant effect on AF. The authors find that an important mechanism of acupuncture in AF treatment is to regulate the cardiac vagus nerve. Therefore, this article intends to review the distribution and function of vagus nerve in the heart, the application and the regulatroy effect for the treatment of AF.

Objective:To investigate the clinical effect of indocyanine green angiography (ICGA)-assisted design and harvest of expanded flaps for scar reconstruction.Methods:This study was a retrospective observational study. From April 2019 to August 2023, 19 patients with scars (8 males, 11 females; aged 3-38 years) treated at the Plastic Surgery Hospital of Peking Union Medical College and Chinese Academy of Medical Sciences met the inclusion criteria. The scars were distributed on the head, face, trunk, and extremities. In stage Ⅰ surgery, skin soft tissue expanders were implanted in suitable areas around the scars for skin soft tissue expansion. In stage Ⅱ surgery, the scar tissue was excised, resulting in wound areas ranging from 100 to 210 cm 2, and expanded flaps were designed. ICGA was used to identify target perforators and their accompanying veins, and the flap design was adjusted to ensure the inclusion of complete arterial and venous axes. The expanded flap with an area of 120 to 240 cm2 was harvested using unilateral back-cut technique and transferred to the recipient site, and the donor site wound was sutured directly. The durations of the arterial and venous phases of ICGA during flap design were recorded. The length-to-width ratios of the back-cut flaps were calculated for different regions. After stage Ⅱ surgery, the blood perfusion and survival of the flap, the wound healing at the donor site, and the occurrence of complications were observed. During follow-up, the appearance, color, and texture of the patient's flap were observed. Results:The arterial phase of ICGA lasted 10-27 (18±5) s, and the venous phase lasted 78-116 (100±10) s. The length-to-width ratios of the back-cut flaps were 1.22±0.32, 1.63±0.12, and 1.15±0.21 for the head and neck, trunk, and limb regions, respectively. After stage Ⅱ surgery, one patient had a large area of insufficient blood perfusion in the flap. By comparing ICGA images before and after flap transfer, the sutures at the oral commissure were loosened, the blood flow of the flap was restored. The blood perfusion of the flaps in other patients was good. All flaps survived completely, with well-healed donor site wounds and no complications. During 0.5-14.0 months of follow-up, all flaps of patients demonstrated excellent appearance, with color and texture matching the surrounding skin.Conclusions:As a means of superficial blood flow visualization, ICGA can not only clearly show the microvascular distribution of the expanded flap before operation, assist in optimizing the design of the flap, but also evaluate the blood perfusion of the flap after operation, reduce the occurrence of complications, and provide a full-process navigation for the harvesting of expanded flaps, thereby improving the safety of flap transfer for scar reconstruction.

Trastuzumab deruxtecan(T-DXd)has demonstrated significant efficacy in clinical trials for human epidermal growth factor receptor 2(HER2)-expressing breast cancer,gastric cancer,lung cancer and other solid tumors.Its overall safety profile is manageable and tolerable,including the clinically concerning interstitial lung disease(ILD).The etiology of ILD is varied,among which drug-induced ILD is an exclusionary diagnosis.The incidence of ILD caused by different antitumor drugs varies with different symptoms,and the pathogenesis remains unclear.T-DXd-induced ILD is mostly Grades 1-2,and implementing a standardized clinical management protocol can reduce the incidence of severe ILD events,improve patient prognosis,and help maximize the clinical benefits of T-DXd.This article summarized the epidemiology,etiology,risk factors,and potential mechanisms of drug-induced ILD,with a focus on the incidence,time to onset,and outcomes of T-DXd-induced ILD after standardized clinical management.It aimed to help readers understand the importance of standardized clinical management before and during T-DXd treatment.Regarding specific clinical management strategies,the article reviewed comprehensive management approaches for T-DXd-induced ILD based on clinical trial protocols and real-world experiences from both domestic and international perspectives,covering patient screening,patient education,ILD monitoring,diagnosis,and treatment.Before initiating T-DXd treatment,patient screening helps identify those at high risk for ILD,and T-DXd should be used cautiously in these high-risk patients.Effective patient education can enhance patient initiative,encouraging them to promptly report suspected symptoms,which contributes to early identification of ILD.During T-DXd treatment,it is important to regularly monitor symptoms and signs related to ILD,implement regular imaging monitoring and leverage multidisciplinary team collaboration to diagnose ILD as early as possible,thereby minimizing the risk of severe ILD.If symptoms or imaging suggest ILD,T-DXd treatment must be immediately interrupted,and relevant examinations should be completed to rule out other possible causes while considering corticosteroid treatment.Upon ILD diagnosis,subsequent T-DXd dose adjustments,corticosteroid therapy,and supportive treatments should be guided by severity.The article also explored whether patients with T-DXd-induced ILD can be re-treated,concluding that Grade 1 ILD patients might be eligible for re-treatment under specific conditions.In conclusion,the article reviewed the epidemiology,characteristics,clinical trial-recommended management strategies,and real-world management measures of T-DXd-induced ILD,integrating clinical expert experiences to summarize and discuss comprehensive management strategies for it.This aimed to enhance clinicians'understanding of T-DXd-induced ILD and provide valuable insights for early identification,timely diagnosis,and proper management of it.

The limitations of antifungal drugs and severe drug resistance make the treatment of invasive fungal infections (IFIs) a great challenge. Itraconazole (ITZ), as a clinical first-line drug, has a wide range of antifungal activity, but it is still limited by adverse reactions such as liver and kidney toxicity, headache and abdominal pain due to its poor water solubility and easy to cause drug accumulation by injection. In this study, the amphiphilic polymer gallic acid-chitosan-cinnamaldehyde (GA-CS-CN) was prepared by amide reaction and Schiff-base reaction. The drug-loaded nanoparticles (GA-CS-CN/ITZ) were prepared by ultrasonic method. The properties of nanoparticles formulations and its in vitro antifungal activity were investigated in the study. Studies have shown that GA-CS-CN/ITZ is spherical, homogeneous and stable, and has good biological safety. The average particle size was 239.57 ± 31.37 nm, ITZ encapsulation efficiency was (93.41 ± 1.12)%, and the cumulative drug release was (62.25 ± 1.88)% at 48 h in vitro. The antifungal activity results of Candida albicans ATCC 10231 (C. albicans) showed that it had the optimal antifungal effect and could significantly enhance the antifungal activity of free drugs. GA-CS-CN/ITZ prepared in this study has excellent biological safety and anti-C. albicans performance, which provides a new choice for the treatment of C. albicans infection and has good application potential in the treatment of this fungal infection.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective: To explore the efficacy of adjuvant programmed cell death 1 (PD-1) monoclonal antibody immunotherapy in Chinese patients with resected stage Ⅱ-Ⅲ melanoma. Methods: A total of 296 patients who underwent radical surgery for stage Ⅱ-Ⅲ cutaneous orlimb melanoma at Fudan University Shanghai Cancer Center and Shanghai Electric Power Hospital between 2017 and 2021 and received adjuvant PD-1 monoclonal antibody immunotherapy, low-dose interferon (IFN), or observational follow-up were enrolled in this study. Patients were divided into the PD-1 monoclonal antibody group (164 cases) and the IFN or observation group (IFN/OBS group, 132 cases) based on postoperative adjuvant treatment methods. Patients' disease recurrence and survival were observed. Results: Among the 296 patients, 77 had cutaneous melanoma and 219 had limb melanoma; 110 were stage Ⅱ and 186 were stage Ⅲ. Among stage Ⅱ patients, the median recurrence-free survival (RFS) in the PD-1 monoclonal antibody group (46 cases) did not reach, while the median RFS in the IFN/OBS group (64 cases) was 36 months. The 1-year RFS rates were 85.3% and 92.1% and the 2-year RFS rates were 71.9% and 63.7% in the PD-1 monoclonal antibody group and the IFN/OBS group, respectively, with no statistically significant difference (P=0.394). Among stage Ⅲ patients, the median RFS rates in the PD-1 monoclonal antibody group (118 cases) and the IFN/OBS group (68 cases) were 23 and 13 months, respectively. The 1-year RFS rates were 70.0% and 51.8% and the 2-year RFS rates were 51.8% and 35.1%in the PD-1 monoclonal antibody group and the IFN/OBS group, respectively, with a statistically significant difference (P=0.010). Stratified analysis showed that the advantage of PD-1 monoclonal antibody adjuvant therapy in improving RFS persisted in the subgroups of primary ulceration (HR=0.558, 95% CI: 0.348-0.893), lymph node macroscopic metastasis (HR=0.486, 95% CI: 0.285-0.828), stage ⅢC (HR=0.389, 95% CI: 0.24-0.63), and the subgroup without BRAF/c-Kit/NRAS gene mutations (HR=0.347, 95% CI: 0.171-0.706). In terms of recurrence patterns, in stage Ⅱ patients, the recurrence and metastasis rate was 15.2% (7/46) in the PD-1 monoclonal antibody group, significantly lower than the IFN/OBS group [43.8% (28/64), P=0.002]. In stage Ⅲ melanoma patients, the recurrence and metastasis rate was 42.4% (50/118) in the PD-1 monoclonal antibody group, also lower than the IFN/OBS group [63.2% (43/68), P=0.006]. Conclusions: In real-world settings, compared with patients receiving low-dose IFN adjuvant therapy or observational follow-up, PD-1 monoclonal antibody immunotherapy can reduce the recurrence and metastasis rate of cutaneous and limb melanoma, and prolong the postoperative RFS of stage Ⅲ cutaneous and limb melanoma patients. Patients with a heavier tumor burden benefit more from immunotherapy.
