BACKGROUND: Metabolic-associated fatty liver disease (MAFLD) is the predominant form of chronic liver disease worldwide. This study was designed to investigate the proportion and characteristics of MAFLD within the general Chinese population and to identify the contributory risk factors for liver fibrosis among MAFLD individuals. METHODS: The participants were recruited from a cohort undergoing routine health evaluations at the Third Hospital of Hebei Medical University between May 2019 and March 2023. The diagnosis of MAFLD was based on the established clinical practice guidelines. The fibrosis-4 index score (FIB-4) was employed to evaluate hepatic fibrosis, with a FIB-4 score of ≥1.3 indicating significant fibrosis. Binary logistic regression analyses were used to determine risk factors associated with significant hepatic fibrosis in MAFLD. RESULTS: A total of 22,970 participants who underwent comprehensive medical examinations were included in the analysis. The overall proportion of MAFLD was 28.77% (6608/22,970), with 16.87% (1115/6608) of these patients showing significant fibrosis as assessed using FIB-4. Independent risk factors for significant liver fibrosis in MAFLD patients were male (odds ratio [OR] = 0.676, 95% confidence interval [CI]: 0.558-0.821), hepatitis B surface antigen (HBsAg) positivity (OR = 2.611, 95% CI: 1.557-4.379), body mass index ≥23.00 kg/m 2 (OR = 0.632, 95% CI: 0.470-0.851), blood pressure ≥130/85 mmHg (OR = 1.885, 95% CI: 1.564-2.272), and plasma glucose ≥5.6 mmol/L (OR = 1.815, 95% CI: 1.507-2.186) (all P <0.001). CONCLUSIONS The proportion of MAFLD in an urban Chinese population is 28.77%. About 16.87% of MAFLD patients presented with significant liver fibrosis. Independent risk factors for significant liver fibrosis in MAFLD patients should be noticed.

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.

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.

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.

Emaciation is a common physical condition in clinical practice,often accompanied by symptoms related to"excessive fire in thin people".Insufficient yin-qi is the main physiological and pathological basis of emaciation,and excessive dryness-heat is the secondary manifestation.The disease involves five viscera,with the spleen as the core.The principle of treatment is to nourish yin-qi as the main method,and to dissipate stagnant heat as the auxiliary method.Specifically,it includes two aspects:treating the root cause and treating the symptoms.Treating the root cause should nourish yin-qi to improve the"emaciation"constitution,and treating the symptoms should dissipate stagnant heat to eliminate the"excessive fire"state.The importance of the two should be determined ac-cording to the severity and urgency of the excessive fire.Clinically,the addition and subtraction of medicinal ingredients are made ac-cording to factors such as the urgency of the root cause and symptoms,the state of emaciation and the ability to eat,the degree of defi-ciency or excess of fire-heat,the pathogenesis of the disease,and the season.
