Tumor metastasis is a primary cause of death among solid tumor patients.Interventions such as chemotherapy with cytotoxic drugs and other targeted therapies focusing on specific genes or tumorigenesis can induce tumor shrinkage in most cases.However,these interventions do not substantially prolong the lives of patients.In recent years,immunotherapy has made significant breakthroughs in treating solid tumors with the introduction of immune checkpoint inhibitors(ICIs),following the clinical use of Ipilimumab,the first anti-tumor drug with ICIs initially approved in 2011.Currently,four types of ICIs including CTLA-4,PD-1,PD-L1,and LAG3 have been clinically applied and have demonstrated specificity towards more than 20 types of solid tumors.The significance of ICIs lies in their superiority to conventional drugs in three aspects:(1)They can prolong the survival of late-stage patients and even achieve"clinical cure";(2)They allow patients with rare tumors access a pan-tumor treatment based on specific biomarkers;and(3)They can free a majority of patients from invasive surgical approaches to preserve organ functions,thereby improving patient's quality of life.This article provides a summary of multiple clinical research projects and explores the clinical evidence derived from the notable achievements related to the three advantages.

OBJECTIVE To analyze the clinicopathological features of laryngeal squamous carcinoma tumors and their correlation with prognosis in order to improve the understanding and diagnosis of laryngeal squamous cell carcinoma.METHODS The clinical and pathological data(including gender,age,stage,differentiation,immunohistochemistry,etc.)of 179 patients with laryngeal squamous cell carcinoma[171 males,8 females,aged 30-84(61.53±8.02)years]who were treated in Department of Otolaryngology Head and Neck Surgery,The First and Second Clinical Medical Schools of Ningxia Medical University from January 2015 to December 2022 were retrospectively studied,and the effects of various factors on prognosis were analyzed.RESULTS Among the 179 patients with laryngeal squamous cell carcinoma,the male-to-female ratio was 21.4:1,and the incidence was high in the age group of 60-79 years old(58.7%),and the youngest age of onset was 30 years old.The main clinical manifestations were hoarseness 138 cases(77.1%),sore throat 16 cases(8.9%)and pharyngeal foreign body sensation 13 cases(7.3%).Glottic type was more common in the primary site 135 cases(75.4%),and 31 cases were accompanied by cervical lymph node metastasis(17.3%).The degree of differentiation was more common in the moderately differentiated type 80 cases(44.7%).The positive rates of immunohistochemistry markers p16,EGFR(epidermal growth factor receptor),PD-1/PD-L1 and VEGF(vascular endothelial growth factor)were 20.3%,96.4%,36.4%and 77.3%,respectively.Univariate Kaplan-Meier survival analysis showed that the site of disease,lymph node metastasis,and tumor stage were significantly correlated with disease recurrence.Multivariate Cox regression analysis showed that the clinical stage of the tumor was an independent risk factor for the prognosis of the disease(HR=3.715,95%CI:1.519-9.088,P=0.04).CONCLUSION The stage of laryngeal squamous cell carcinoma,the site of the disease,and the metastasis of the lymph nodes are the main factors affecting the prognosis.The high positive expression rate of immunohistochemistry markers EGFR and VEGF is worth paying attention to Targeted therapy for patients with positive PD-1/PD-L1 testing is a promising research direction.

Monogenic inherited skin diseases are a group of clinically rare diseases that include nearly 1000 phenotypically distinct disorders. Through the concerted efforts of researchers in dermatological sciences and related disciplines worldwide, many advances have been made in the etiology and pathogenesis of these diseases in the last 30 years. However, it is important to note that the treatment of the majority of monogenic inherited skin diseases remains a challenge for clinicians. Dupilumab is a fully human monoclonal IgG4 antibody that specifically binds to the α subunit of the IL-4 receptor, thereby inhibiting the IL-4 and IL-13 signaling pathway. It was first approved for the treatment of moderate-to-severe atopic dermatitis (AD) and has been used worldwide. In recent years, the drug has been successfully used to treat some monogenic inherited skin diseases with AD-like clinical manifestations, such as hyper-IgE syndrome and Netherton syndrome, with good efficacy. The drug was later tried for the treatment of other monogenic inherited skin diseases, such as Hailey-Hailey syndrome and epidermolysis bullosa pruriginosa, where it was also proven to be effective. In this paper, we review literature reports related to dupilumab for the treatment of monogenic inherited skin diseases in recent years, focusing on its efficacy, safety and possible therapeutic mechanisms. We aim to provide a possible scientific basis for the future application of this drug in the field of rare monogenic inherited skin diseases.

Objective:To explore the accuracy of artificial intelligence (AI) system based on deep learning in evaluating bone age of children with abnormal growth and development.Methods:The positive X-ray films of the left wrist of children with abnormal growth and development who were treated at the Affiliated Hospital of Guizhou Medical University from January 2020 to December 2021 were collected retrospectively. A total of 717 children were collected, including 266 males and 451 females, aged 2-18 (11±3) years. Based on Tanner Whitehouse 3 (TW 3)-RUS (radius, ulna, short bone) and TW3-Carpal (carpal bone) method, bone age was measured by 3 senior radiologists, and the mean value was taken as reference standard. The bone ages were independently evaluated by the AI system (Dr.Wise bone age prediction software) and two junior radiologists (physicians 1 and 2). The accuracy within 0.5 year, the accuracy within 1 year, the mean absolute error (MAE) and the root mean square error (RMSE) between the evaluation results and the reference standard were analyzed. Paired sample t-test was used to compare MAE between AI system and junior physicians. Intraclass correlation coefficient (ICC) was used to evaluate the consistency between AI system, junior physician and reference standard. The Bland-Altman diagram was drawn and the 95% consistency limit was calculated between AI system and reference standard. Results:For TW3-RUS bone age, compared with the reference standard, the accuracy within 0.5 year of AI system, physician 1 and physician 2 was 75.3% (540/717), 62.1% (445/717) and 66.2% (475/717), respectively. The accuracy within 1 year was 96.9% (695/717), 86.3% (619/717) and 89.1% (639/717), respectively. MAE was 0.360, 0.565 and 0.496 years, and RMSE was 0.469, 0.634 and 0.572 years, respectively. For TW3-Carpal bone age, compared with the reference standard, the accuracy within 0.5 year of AI system, physician 1 and physician 2 was 80.9% (580/717), 65.1% (467/717) and 71.7% (514/717), respectively. The accuracy within 1 year was 96.0% (688/717), 87.3% (626/717) and 90.4% (648/717), respectively. MAE was 0.330, 0.527 and 0.455 years, and RMSE was 0.458, 0.612, 0.538 years, respectively. Based on TW3-RUS and TW3-Carpal bone age, the MAE of AI system were lower than those of physician 1 and physician 2, and the differences were statistically significant ( P all<0.001). The evaluation results of AI, physician 1 and physician 2 were in good agreement with the reference standard (ICC all>0.950). The Bland-Altman analysis showed that the 95% agreement limits of AI system for assessing TW3-RUS and TW3-Carpal bone age were -0.75-1.02 years and-0.86-0.91 years, respectively. Conclusion:The accuracy of AI system in evaluating the bone age of children with abnormal growth and development is close to that of senior doctors, better than that of junior doctors, and in good agreement with senior doctors.

Waterborne viruses that can be harmful to human health pose significant challenges globally,affecting health care systems and the economy.Identifying these waterborne pathogens is essential for preventing diseases and protecting public health.However,handling complex samples such as human and waste-water can be challenging due to their dynamic and complex composition and the ultralow concentration of target analytes.This review presents a comprehensive overview of the latest breakthroughs in waterborne virus biosensors.It begins by highlighting several promising strategies that enhance the sensing performance of optical and electrochemical biosensors in human samples.These strategies include optimizing bioreceptor selection,transduction elements,signal amplification,and integrated sensing systems.Furthermore,the insights gained from biosensing waterborne viruses in human sam-ples are applied to improve biosensing in wastewater,with a particular focus on sampling and sample pretreatment due to the dispersion characteristics of waterborne viruses in wastewater.This review suggests that implementing a comprehensive system that integrates the entire waterborne virus detection process with high-accuracy analysis could enhance virus monitoring.These findings provide valuable insights for improving the effectiveness of waterborne virus detection,which could have sig-nificant implications for public health and environmental management.

Objective To investigate the diagnostic value of high-resolution magnetic resonance im-aging(HRMRI)in elderly patients with non-cardioembolic acute ischemic stroke(NCAIS).Meth-ods A retrospective analysis was conducted on 101 elderly NCAIS patients having HRMRI in our hospital from July 2022 to July 2023.Stroke subtypes were classified according to the Trial of Org 10172 in Acute Stroke Treatment(TOAST)system and the Chinese Ischemic Stroke Sub-classification(CISS)system.The constituent ratio distribution of each subtype classification was compared before and after HRMRI in both classification systems.Results TOAST system identi-fied 8 cases of small-artery occlusion(SAO),1 case of other determined etiology(SOE),5 cases of undetermined etiology(SUE)and then reclassified as large artery atherosclerosis(LAA),1 case of SUE which was reclassified as SAO,and 7 cases of LAA and 4 cases of SUE being reclas-sified as SOE after HRMRI.In total,the diagnosis of 26 cases(25.74％)was modified.In the CISS system,10 cases of penetrating artery disease(PAD),1 case of other etiologies(OE),and 4 cases of undetermined etiology(UE)were reclassified as LAA.Furthermore,9 cases of LAA and 3 cases of UE were reclassified as OE after HRMRI.In total,the diagnosis of 27 cases(26.73％)was modified.There were statistical differences in the constituent ratio before and after HRMRI in both TOAST(x2=15.425,P＜0.01)and CISS(x2=17.300,P＜0.01)systems.Conclusion HRMRI is of diagnostic value and significance in accurately diagnosing the etiology of AIS in eld-erly patients without cardioembolic causes.

Objective:To investigate the efficacy and safety of traditional laser photocoagulation, laser combined with intravitreal injection of anti-vascular endothelial factor (anti-VEGF) drugs and intravitreal injection of anti-VEGF drugs alone in Coats disease.Methods:The patients diagnosed as Coats disease stage 2B-3A2 in Department of Ophthalmology, Eye and ENT Hospital of Shanghai Medical College of Fudan University from December 2016 to November 2019 were included in this study. Patients were divided into three groups, including laser group, combined group and drug group, according to the different treatment. In the laser group, the initial treatment was traditional laser photocoagulation alone. In the drug group, the anti-VEGF drug was injected into vitreous once a month for three months. The initial treatment of the eyes in the combined group was laser combined with intravitreal injection of anti-VEGF drugs, or laser treatment within 1 week after anti-VEGF drug treatment. The follow-up time was more than 6 months, and best-corrected visual acuity (BCVA), ultra-wide-angle fundus photography, and fluorescein fundus angiography were performed during follow-up. The treatment efficiency, subretinal fluid (SRF), macular edema, BCVA and complications were compared among the three groups.Results:Among 60 patients (60 eyes), there were 55 males (55 eyes) and 5 females (5 eyes), with the mean age of 17.1±2.0 years. Among 60 eyes, there were 26 eyes in 2B stage, 23 eyes in 3A1 stage, and 11 eyes in 3A2 stage. Twenty patients (20 eyes) was in the laser group, combined group and drug group, respectively. After the initial treatment of all eyes in the drug group, the abnormal blood vessels did not regress significantly; the absorption and increase of SRF were 4 (20.0%, 4/20) and 5 (25.0%, 5/20) eyes, respectively. Supplementary laser therapy was given to 16 eyes, and vitrectomy (PPV) was given to 4 eyes. Among the 16 eyes treated by laser, 10 eyes were effective (50.0%, 10/20); vitreous hemorrhage, fibrous membrane hyperplasia, and complicated cataract occurred in 1, 1, and 2 eyes during the treatment, respectively, and PPV was given again in all eyes. Recurrent and persistent macular edema occurred in 4 and 1 eyes, respectively. Among the eyes in the combined group, treatment were effective in 11 eyes (55.0%, 11/20); 5, 2, and 2 eyes had SRF, fibrous membrane hyperplasia, and complicated cataract during the treatment, and PPV was given again; the edema was repeated and persisted in 1 eye, respectively. Among the affected eyes in the laser group, 15 eyes (75.0%, 15/20) were treated effectively; 2, 2, and 1 eyes developed a large number of vitreous hemorrhage, fibrous membrane hyperplasia, and complicated cataract during the treatment, and PPV was given again.Conclusions:Anti-VEGF drugs alone are ineffective in the treatment of Coats disease, and ablation of other abnormal blood vessels is needed. In the treatment of Coats disease, anti-VEGF drugs can not only promote the absorption of SRF, but also may lead to its increase, and the application should be cautious.
