Total laryngectomy is a crucial surgical intervention for patients with advanced malignant tumors of the larynx and nasopharynx. Despite its effectiveness, this procedure permanently severs the connection between the nasal cavity and the lower respiratory tract, leading to the cessation of nasal airflow. This disruption significantly impairs the patient's sense of smell and adversely affects their quality of life. Although olfactory loss is common in these patients, the assessment and rehabilitation of their olfactory function are often overlooked. This article reviews relevant literature on evaluating olfactory function and rehabilitation methods following total laryngectomy, with the aim of providing a theoretical foundation to enhance olfactory rehabilitation and overall quality of life for these patients.

Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

The cultivation of innovation ability is not only the essential requirement of graduate education,but also the strate-gic demand of the development of the communist party and our country,and is of great significance to the realization of the Chinese dream of the great rejuvenation of the Chinese nation.Curriculum ideology and politics should run through the whole process of post-graduate innovation ability training.However,the curriculum ideology and politics and postgraduate innovation ability training lack deep integration.It's important for postgraduates'growth and scientific research innovation that the curriculum ideology and politics covers the whole process of scientific research activities.Therefore,this paper focuses on the design and specific implementation schemes of the curriculum ideology and politics on the postgraduate innovative ability training at the respiratory disease research team in the department of medical immunology.It makes a basis for optimizing postgraduate curriculum ideology and politics teaching in the future,which also provides ideas for cultivating innovative talents with both morality and ability in medical specialty.

Diagnosis and treatment of digestive tract tumors is not optimistic with high incidence and mortality.Early diagnosis is conducive to improving the survival rate and quality of life of the patients.A variety of endoscopic imaging techniques have been applied in the diagnosis of digestive tract tumors,each with its own advantages and disadvantages.Optical coherence tomography(OCT)has emerged as a non-invasive and high-resolution imaging technique with unique advantages in staging and diagnosis of superficial digestive tract tumors.The complexity of massive image processing has also been effectively addressed with the development of artificial intelligence(AI),and AI-assisted OCT imaging,especially in the diagnosis of digestive tract tumors,has shown good prospects.This review summarizes the principle and development of OCT,and discusses the potential of AI-assisted OCT for deep learning in the diagnosis of digestive tract tumors.

Objective To assess the efficacy of a novel inguinal tourniquet in healthy individuals and to investigate the relationship between localized inguinal compression and femoral artery blood flow occlusion.Methods A self-controlled study was conducted.From November 9 to November 30,2024,11 volunteers were recruited at the Third Medical Center of Chinese PLA General Hospital.Three compression methods--finger pressure,a novel groin tourniquet,and a SAM junction tourniquet(SJT)—were applied bilaterally to the inguinal region until distal blood flow signals disappeared.Each compression method was tested in 22 trials with a 5-minute interval between operations.Differences in hemostatic efficacy between bilateral inguinal regions and across compression methods were compared.Subsequently,the novel tourniquet was incrementally pressurized in 120 mmHg multiples using an integrated pressure device to analyze trends in popliteal artery blood flow velocity.Observational indicators included the internal pressure of the tourniquet pressurization device,peak systolic velocity(PSV)of popliteal artery,inguinal surface pressure magnitude,inguinal surface pressure distribution,and pain scores(assessed using a single-dimensional numerical rating scale).Results No statistically significant difference was observed in the minimum pressure required to occlude femoral artery blood flow bilaterally(P>0.05).The success rates of femoral artery blood flow occlusion at the inguinal region were 100%for the novel inguinal tourniquet,SJT,and finger pressure.The novel inguinal tourniquet induced the highest pain scores,ranging from 5 to 8.A significant reduction in PSV of popliteal artery was noted when the intra-tourniquet pressure reached 360 mmHg and 480 mmHg(P<0.05),with a 95%hemostasis efficacy observed within the range of 360-600 mmHg.No significant association was observed between the recovery of popliteal artery blood flow after limb movement and inguinal pressure distribution(P>0.05).The PSV of popliteal artery exhibited the strongest negative correlation with the average pressure within the inguinal compression area(r=-0.79,P<0.001),with a linear regression fitting line of y=69.69-0.13x(P<0.001,R2=0.58).Conclusions The novel inguinal tourniquet effectively occludes femoral artery blood flow within a pressure range of 360-600 mmHg,accompanied by moderate-to-severe pain.Its hemostatic mechanism mainly relies on increasing the mean pressure within the inguinal compression area.

Objective:To analyze and explore the diagnostic value of endoscopic submucosal dissection (ESD) for primary gastrointestinal lymphoma (PGIL).Methods:A retrospective analysis was conducted on the clinical and pathological data from 37 patients with suspected PGIL and admitted to Zhongshan Hospital, Fudan University and Xiamen Hospital, Zhongshan Hospital, Fudan University between January 2021 and December 2023. The diagnostic accuracy for PGIL of initial endoscopic conventional biopsies was compared with that of ESD biopsies.Results:Among these patients, 6 were diagnosed as having primary gastrointestinal lymphoma by routine endoscopic biopsy, with a diagnostic rate of 16.22% (6/37). Of the 22 patients who underwent ESD, 20 were diagnosed as having primary gastrointestinal lymphoma, achieving a diagnostic rate of 90.91% (20/22), which was significantly higher than that of initial endoscopic routine biopsies ( χ2=31.228, P<0.05). Conclusion:ESD demonstrates significant diagnostic value for PGIL.
