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.

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.

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.

Objective To explore the effects of different side tension pneumothorax on hemodynamics in pigs,providing data support for the optimization of on-site first-aid procedures for pneumothorax.Methods Twelve Bama pigs were randomly divided into left-sided tension pneumothorax group and right-sided tension pneumothorax group(6 in each group).During the occurrence of pneumothorax and as the pleural pressure gradually increases by 1 mmHg increments,the key indicators were collected using pulse indicator continuous cardiac output(PICCO)technology:hemodynamic indicators[global ejection fraction(GEF),cardiac output(CO),global end-diastolic volume(GEDV),intrathoracic blood volume(ITBV),stroke volume(SV),mean arterial pressure(MAP)],basic vital signs[heart rate(HR),diastolic blood pressure(DBP),systolic blood pressure(SBP)],and arterial blood gas parameters[partial pressure of oxygen(PO2),partial pressure of carbon dioxide(PCO2)].Mediastinal localization was subsequently performed using radiographs.Differences were investigated through comparison between the two groups and within each group before and after the procedure.Results By comparing the hemodynamic changes and X-ray examination results,twelve Bama pigs tension pneumothorax models were successfully constructed.Hemodynamic analysis showed that in left-sided tension pneumothorax model when the pleural pressure reached 8 mmHg,SBP,DBP,MAP,CO,GEF,SV,GEDV and ITBV were significantly lower than those during the occurrence of ipsilateral pneumothorax(P<0.05).In right-sided tension pneumothorax model,when the pleural pressure reached about 3 mmHg,SBP,DBP,MAP,SV,GEDV,and ITBV were significantly lower than those during the occurrence of ipsilateral pneumothorax(P<0.05).Blood gas analysis showed that at 8 mmHg for left-sided and 3 mmHg for right-sided tension pneumothorax,compared with the occurrence of their respective ipsilateral pneumothorax,PO2 was significantly lower(P<0.05)and PCO2 was significantly higher(P<0.05).Conclusions There are different effects on hemodynamics in different side tension pneumothorax.Compared with left tension pneumothorax,right tension pneumothorax can lead to serious consequences under a smaller pleural pressure.Different side tension pneumothorax models can be constructed according to the actual situation when performing pneumothorax related experiments.

ObJective·To evaluate the dentofacial phenotype in non-syndromic tooth agenesis(NSTA)patients with paired box gene 9(PAX9)mutation.Methods·Patients with NSTA who visited the Department of Second Dental Center of Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine,between January 2016 and December 2023 received whole-exome sequencing to screen PAX9 mutation.The location and number of missing teeth were evaluated by oral pantomography,and dentofacial deformities were evaluated by X-ray cephalometrics.Results·Seven patients with PAX9 mutation were included in the study,including 3 males(42.9％)and 4 females(57.1％).The patients were 7-31 years old at first visit,with a mean age of(19.7±8.0)years old.All the 7 patients were PAX9 heterozygotes,of which 4 were missense and 3 were frameshift.The average number of missing teeth was 15.9±2.9.The number of missing teeth in maxilla(9.6±2.6)was slightly higher than that in mandible(6.3±2.4)(P=0.030).Maxillary second molar(100.0％),maxillary canine(85.7％)and mandibular second premolar(85.7％)were the three most common missing teeth,while mandibular lateral incisor(14.3％)and mandibular canine(14.3％)were the two least missing teeth.Patients with frameshift mutation had more missing teeth(18.3±2.1)than those with missense mutation(14.0±1.8)(P=0.032).X-ray cephalometrics analysis results showed that the angle sella-nasion-subspinale(SNA),angle nasion-subspinale-subspinale-porion(NA-Apo)and sella-nasion(S-N)in adult patients with PAX9 mutation were significantly lower than the normal reference values,suggesting a shorter anterior cranial base and maxillary length.The frankfort horizontal plane-nasion-porion(FH-NPo)was higher than the reference value,and the Y-axis was lower than the reference value,indicating a more prognathic mandible.The angle subspinale-nasion-supramental(ANB)was lower than the reference value,indicating a skeletal angle Ⅲ malocclusion.The angle upper central incisor-nasion-subspinale(angle U1-NA)was higher than the reference value,indicating a lip inclination of maxillary central incisor.The angle lower central incisor-mandibular plane(IMPA)and lower central incisor-nasion-supramental(L1-NB)were lower than the reference values,indicating a retroclination of the mandibular central incisor,and crossbite in the maxillary and mandibular anterior teeth.Conclusion·The dentofacial phenotype of PAX9-mutated patients with NSTA is reported comprehensively.It is helpful to improve the understanding of the role of PAX9 in human maxillofacial development.

Objective·To explore the influencing factors of oral nutritional supplement compliance in postoperative patients with digestive tract cancer based on COM-B model,and to analyze the mediating role of medication belief and self-efficacy in oral nutritional supplement.Methods·A total of 300 postoperative gastrointestinal cancer patients were selected by convenience sampling method.The General Information Questionnaire,Morisky Medication Adherence Scale,Digestive Cancer Patients Nutrition Knowledge,Attitude and Practice Questionnaire,Multidimensional Scale of Perceived Social Support,Beliefs about Medicines Questionnaire and General Self-Efficacy Scale were used.A mediating effect model was used to analyze the influencing factors of compliance with oral nutritional supplements.Results·The score of Morisky Medication Adherence scale was 1.61±1.38,which was at a low level.Oral nutritional supplement compliance was significantly positively correlated with nutrition knowledge,social support,medication belief and self-efficacy(r=0.391,0.401,0.438,0.410,all P＜0.01).Medication belief had a partial mediating effect between nutrition knowledge and adherence to oral nutritional supplements(effect size=0.097,accounting for 18.00%of the total effect).Self-efficacy had a partial mediating effect between nutrition knowledge and oral nutritional supplement compliance(effect size=0.044,accounting for 8.16%of the total effect).Self-efficacy had a partial mediating effect between social support and oral nutritional supplement compliance(effect size=0.044,accounting for 16.67%of the total effect).Conclusion·The compliance of oral nutritional supplements in postoperative patients with gastrointestinal cancer is at a low level.The individualized nursing intervention can increase the nutritional knowledge of patients,improve the social support,reduce the concerns of patients about oral nutrition,and improve the self-efficacy of patients,so as to promote the compliance of patients with oral nutritional supplements.

Objective:To analyze the efficacy and influencing factors of cyclosporine(CsA)alone in the treatment of children with acquired aplastic anemia(AA).Methods:The clinical data of children diagnosed with AA and treated with CsA alone from January 1,2016 to December 31,2020 in the Children's Hospital of Chongqing Medical University were collected,and the efficacy and influencing factors of CsA treatment were evaluated.Results:Among the 119 patients,there were 62 male and 57 female,with a median age of 7 years and 1 month.There were 45 cases of very severe AA(VSAA),47 cases of severe AA(SAA),and 27 cases of non-severe AA(NSAA).At 6 months after treatment,the efficacy of VSAA was lower than that of SAA and NSAA,and there was a statistical difference(P＜0.01).6 cases died early,16 cases relapsed,2 cases progressed to AML and ALL.The results of univariate analysis showed that the high proportion of lymphocyte in the bone marrow at 6 months was an adverse factor for the efficacy of CsA,while high PLT count was a protective factor(P=0.008,P=0.002).The ROC curve showed that the cut-off values of PLT count and the proportion of bone marrow lymphocyte at 6 months were 16.5 × 109/L,68.5％,respectively.Multivariate analysis showed that the high proportion of lymphocyte in bone marrow at 6 months was an independent adverse factor for IST(P=0.020,OR=0.062),and high PLT count was a protective factor(P=0.044,OR=1.038).At 3 months of treatment,CsA response and NSAA were the risk factor for recurrence(P=0.001,0.031).Conclusion:The efficacy of NSAA was higher than that of SAA and VSAA after 6 months of treatment with CsA alone.A high PLT count at the initial diagnosis was a good factor for the effectiveness of CsA,and a high proportion of bone marrow lymphocyte was an unfavorable factor.CsA response at 3 months and NSAA were risk factors for recurrence.

Objective:To explore the gene mutations of Langerhans cell histiocytosis in children,and to analyze the correlation of BRAF V600E mutation with clinical features and prognosis of LCH,so as to provide reference for clinical diagnosis and treatment. Methods:Fluorescence PCR was used to detect gene mutations in paraffin-embedded tissue samples from 78 children with LCH,and the correlation of BRAF V600E mutation with clinical characteristics and prognosis of LCH in children was analyzed. Results:Among the 78 children,41 cases (52.6％) had BRAF V600E mutation,8 cases (10.3％) had MAP2K1 mutation,1 case (1.3％) had BRAF Exon 12 mutation,1 case (1.3％) had ARAF mutation,and 1 case (1.3％) had PIK3CA mutation. BRAF V600E mutation was not significantly correlated with sex,age,multisystem involvement,risk-organ involvement,CNS-risk lesions,and early treatment response in children with LCH (P>0.05),and it was also not significantly correlated with the recurrence and event-free survival (EFS) of children with LCH (P>0.05). Conclusion:LCH is an inflammatory myeloid tumor. BRAF V600E mutation is not correlated with clinical features,early treatment response,recurrence and prognosis of LCH.
