OBJECTIVE To investigate the prognostic factors of chondrosarcoma of the larynx,deeply analyze its clinical data,and provide a theoretical basis for better treatment of chondrosarcoma of the larynx.METHODS A retrospective analysis was conducted on the complete clinical data of patients with primary chondrosarcoma of the larynx admitted to the Department of Otolaryngology Head and Neck Surgery,Beijing Tongren Hospital,Capital Medical University from January 2010 to December 2024.RESULTS A total of 15 patients were included,including 11 males and 4 females,with a gender ratio of 11∶4.The average age of onset was 57.3 years,and the average clinical symptom duration was 12.2 months.The tumors were mainly located in the cricoid cartilage in 11 patients,in the arytenoid cartilage in 2 patients,and in the thyroid cartilage in 2 patients.Tumor grading showed that 7 patients were grade I and 8 were grade II.Four patients underwent transoral laser minimally invasive surgery,2 patients underwent partial laryngectomy+tracheotomy,and 9 patients underwent total laryngectomy/cervical lymph node dissection+tracheostomy.The 5-year overall survival rate was 85.7%,the 5-year disease-specific survival rate was 100%,and the 5-year local-regional control rate was 90.9%.Gender,tumor location,tumor grade,Ki-67,tumor size,and whether larynx preservation surgery was performed did not affect the local-regional control rate or disease-specific survival rate.CONCLUSION Laryngeal chondrosarcoma generally has a longer disease history and is difficult to detect.The pathological type is mostly well-differentiated.Regional or distant metastasis is rare,and the long-term survival rate is good.Surgical resection is the preferred treatment option.On the basis of not reducing the tumor control rate,surgery that prioritizes preserving laryngeal function should be given priority,while comprehensive treatment is generally not recommended.

Objective To examine the safety, efficacy and durability of totally endoscopic minimally invasive (TEMI) mitral valve repair in Barlow’s disease (BD). Methods A retrospective study was performed on patients who underwent mitral valve repair for BD from January 2010 to June 2021 in the Guangdong Provincial People’s Hospital. The patients were divided into a MS group and a TEMI group according to the surgery approaches. A comparison of the clinical data between the two groups was conducted. Results A total of 196 patients were enrolled, including 133 males and 63 females aged (43.8±14.9) years. There were 103 patients in the MS group and 93 patients in the TEMI group. No hospital death was observed. There was a higher percentage of artificial chordae implantation in the TEMI group compared to the MS group (P=0.020), but there was no statistical difference between the two groups in the other repair techniques (P>0.05). Although the total operation time between the two groups was not statistically different (P=0.265), the TEMI group had longer cardiopulmonary bypass time (P<0.001) and aortic clamp time (P<0.001), and shorter mechanical ventilation time (P<0.001) and postoperative hospitalization time (P<0.001). No statistical difference between the two groups in the adverse perioperative complications (P>0.05). The follow-up rate was 94.2% (180/191) with a mean time of 0.2-12.4 (4.0±2.4) years. Two patients in the MS group died with non-cardiac reasons during the follow-up period. The 3-year, 5-year and 10-year overall survival rates of all patients were 100.0%, 99.2%, 99.2%, respectively. Compared with the MS group, there was no statistical difference in the survival rate, recurrence rate of mitral regurgitation, reoperation rate of mitral valve or adverse cardiovascular and cerebrovascular events in the TEMI group (P＞0.05). Conclusion TEMI approach is a safe, feasible and effective approach for BD with a satisfying long-term efficacy.

Objective To explore the pathogenesis and prognostic factors of liposarcoma in the head and neck region, and simultaneously analyze the efficacy of different treatment regimens. Methods A retrospective analysis was performed on all patients with primary untreated head and neck liposarcoma who were diagnosed and underwent surgical treatment at our hospital from January 2008 to January 2024. All patients were monitored during follow-up, and their prognoses were analyzed using SPSS software. Results A total of 30 patients were included in the study. Liposarcoma accounted for up to 60% of the cases in the orbit, while the remaining liposarcomas were primarily located in various interspaces of the neck. Dedifferentiated liposarcoma was the most common type, comprising 33%, while myxoid pleomorphic liposarcoma was the rarest at 4%. The tumor pathological type (P<0.001) and Ki67 (P=0.014) significantly affected the tumor control rate. However, an analysis of disease-specific survival rates revealed no significant differences across various factors (all P>0.05). Conclusion The prognosis of head and neck liposarcoma is better compared to that of liposarcomas in other parts of the body. However, myxoid pleomorphic liposarcoma, pleomorphic fat sarcoma, and high Ki67 levels are indicators of poor prognosis. Additionally, postoperative adjuvant radiotherapy does not significantly enhance disease-specific survival rates.

OBJECTIVE: Ulcerative colitis is closely associated with intestinal stem cell (ISC) loss and impaired intestinal mucus barrier. Sinisan (SNS), a compound Chinese herbal medicine, has a long history in the treatment of intestinal dysfunction, yet whether SNS can relieve acute experimental colitis by modulating ISC proliferation and secretory cell differentiation has not been studied. Our study tested the effect of SNS against acute colitis and focused on the mechanisms involving intestinal barrier recovery. METHODS: Network pharmacology analysis and blood entry component analysis of SNS were used to explore the underlying mechanism by which SNS affects the acute dextran sulfate sodium (DSS)-induced murine colitis model. RNA-sequencing was used to demonstrate the mechanism. Further, reverse transcription-quantitative polymerase chain reaction, immunofluorescence staining, and alcian blue and periodic acid-Schiff staining were performed in vivo and in the colonic organoids to investigate the cell lineage differentiation-related mechanism of SNS. Furthermore, potential active ingredients from SNS were predicted by network pharmacology analysis. RESULTS: SNS dramatically suppressed DSS-induced acute colonic inflammation in mice. RNA-sequencing analysis revealed downregulation of inflammation and apoptosis-related genes, and upregulation of lipid metabolism and proliferation-related genes, such as Irf7, Pparα, Clspn and Hspa5. Additionally, ISC renewal and intestinal secretory cell lineage commitment were significantly promoted by SNS both in vivo and in vitro in colonic organoids, leading to enhanced mucin expression. Furthermore, potential active ingredients from SNS that mediated inflammation, lipid metabolism, proliferation, apoptosis, stem cells and secretory cells were predicted using a network pharmacology approach. CONCLUSION Our study shed light on the underlying mechanism of SNS in attenuating acute colitis from the perspective of ISC renewal and secretory lineage cell differentiation, suggesting a of novel therapeutic strategy against colitis.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Objective:To explore the application effect of the Seminar immersion method combined with the problem-oriented three-part method in the cultivation of student post competencies such as academic performance, learning enthusiasm, thinking ability, and application of clinical problems in pathophysiology.Methods:A total of 90 students from the Natural Science Teaching Class of the School of Medicine, Sun Yat-sen University (Large Class One and Large Class Two of the students enrolled in 2022 majoring in clinical medicine) were selected as the research subjects. Before the start of the study, a comparative analysis was conducted on the baseline data such as sex, age, and admission scores of the two classes, and it was confirmed that there were no significant differences. Subsequently, the random coin-tossing method was adopted to select Large Class One ( n=45) as the experimental group, and the problem-oriented three-part method combined with the Seminar immersion method was used. Large Class Two (n=45) was used as the control group, and the traditional teaching method was adopted. The teaching content was hepatic dysfunction. The teaching effect was evaluated based on the theoretical assessment results of the before-class, during-class, and after-class exercises and the scenario analysis questions in the after-class exercises, as well as a teaching satisfaction survey. The data were analyzed using SPSS 26.0 software. Measurement data were expressed as the M ( Q1, Q3), and the Mann-Whitney U test was used for comparison between the two groups. The counting data were analyzed by chi-square test. Results:The in-class and after-class scores of the experimental group were 40.00(20.00,40.00) and 70.00(60.00,70.00) points respectively, which were higher than those of the control group, which were 20.00(20.00,40.00) and 60.00(50.00,70.00) points. The scores of the three scenario analysis questions in the experimental group were 10.00(10.00,10.00),10.00 (10.00,10.00), and 10.00(10.00,10.00) points respectively, and the rank averages were 50.00, 51.00, and 53.50 points respectively. All were higher than the average rank values of the control group, which were 41.00, 40.00, and 37.50 points respectively. The differences were statistically significant (all P<0.05). Furthermore, The satisfaction of students in the experimental group with the new model in terms of enhancing learning interest by 5.00(5.00,5.00) points, solving clinical problems by 5.00(5.00,5.00) points, and cultivating clinical thinking by 5.00(5.00,5.00) points was higher than that of the control group by 4.00(4.00,5.00), 4.00(3.00,5.00), and 4 .00(3.00,5.00) points, and the difference was statistically significant ( P<0.001). Conclusions:The Seminar immersion method combined with the problem-oriented three-part method is helpful to improve the course grades of medical undergraduates and is effective in the cultivation of multiple post competencies. It is worthy of further application and promotion.

OBJECTIVE To investigate the role of Bai Ling Long Zao An Shen formula(BLLZ)in sleep improvement in an environmental stress-induced insomnia rat model and explore its underlying mechanisms.METHODS(1)Component analysis:the chemical constituents of the BLLZ extract were analyzed using ultra-high performance liquid chromatography-mass spectrometry(UPLC-MS).(2)Eval-uation of the sedative and hypnotic effect:① Mice:50 ICR mice were randomly divided into normal control group,BLLZ-L group(5,10 and 20 g·kg-1)and diazepam group(DZP,3 mg·kg-1).After five days of intragastric administration,pentobarbital sodium-induced righting reflex and locomotor activity tests were performed.② Rats:8 SD rats were implanted with electrodes and allowed to recover for seven days before baseline EEG data was collected over 24 h.A crossover design(7 d washout period)was employed,with rats randomly assigned to the DZP(3 mg·kg-1)and BLLZ(20 g·kg-1)group.After five days of treatment,24 h EEG recordings were obtained.(3)Insomnia model and interventions:①8 SD rats were allowed to recover for seven days post-surgery,followed by 6 h(14:00-20:00)baseline EEG recording.A 3×3 crossover design was used to assign rats to model(environmental stress-induced insomnia),model+DZP,or model+BLLZ groups.After five days of treatment,insomnia was induced by frequent cage changes(14:00,16:00 and 18:00),and EEG changes were monitored.(4)Mechanistic study:32 SD rats were randomly divided into the normal control group,model group,and model+DZP group.After five days of treatment,hypothalamic tissues were collected for biochemi-cal analysis.γ-aminobutyric acid(GABA),glutamate(Glu),and dopamine(DA)levels were measured using biochemical kits while γ aminobutyric acid receptor subunit alpha-1(GABAA1),core clock proteins period circadian regulator 2(PER2)and circadian locomotor output cycles(CLOCK)protein expressions were assessed by Western blotting.RESULTS(1)Compared with the normal control group,the sleep latency of BLLZ 10 and 20 g·kg-1 and DZP groups was significantly shortened,and the locomotor activity of BLLZ 20 g·kg-1 and DZP groups was significantly reduced;BLLZ 20 g·kg-1 signifi-cantly increased the total sleep time,slow-wave sleep time,and average duration of sleep in normal rats,and significantly reduced the wakefulness time.(2)The total sleep time and slow-wave sleep time of the model group significantly decreased and the wakefulness time significantly increased compared with baseline.(3)Compared with the model group,the total sleep time and slow-wave sleep time of the model+BLLZ group and the model+DZP group were significantly increased,and the wakefulness time significantly shortened.(4)Compared with the normal control group,the Glu/GABA ratio,DA content and CLOCK protein expression were significantly increased and GABAA1 and PER2 protein expres-sion were significantly decreased in the model group;compared with the model group,the Glu/GABA ratio,DA content and CLOCK protein expression were significantly decreased,and the expression of GABAA1 and PER2 were significantly increased in the model+BLLLZ group and the model+DZP group.CONCLUSION BLLZ has sedative and hypnotic effects.It can prolong the total slow-wave sleep time by increasing the average duration of slow-wave sleep episodes,thereby increasing the total sleep time and improving environmental stress-induced insomnia.The mechanism may be related to the downregulation of the Glu/GABA ratio and DA levels as well as the enhancement of GABAA1 expressions and the regulation of hypothalamic core clock protein expressions.

Objective To investigate the epidemiological status and molecular characteristics of diarrheagenic Escherichia coli(DEC)infection in Xiangshan County,providing a basis for its infection surveillance and outbreak control.Methods The real-time fluores-cence quantitative PCR(qRT-PCR)was used to detect virulence genes in isolated E.coli strains.The identified DEC strains were per-formed whole genome sequencing(WGS).The sequencing data were utilized for bacterial resistance gene analysis,multilocus sequence typing(MLST),and core genome multilocus sequence typing(cgMLST).Results A total of 29 DEC strains were isolated,with a detection rate of 9.8%.Enteroaggregative E.coli(EAEC)and enterotoxigenic E.coli(ETEC)were the main strains,accounting for 51.7%and 31.1%,respectively,while enteropathogenic E.coli(EPEC)had a relatively low proportion(17.2%).Drug resistance gene analysis showed that these strains were generally resistant to multiple antibiotics such as fluoroquinolones and carbapenems.MLST typing identified 19 sequence types(STs),including one novel ST type(STcpEC1).Among them,ST117,ST2178,ST31,and ST48 were dominant types.ETEC strains were mainly concentrated in the clonal complex CC-10,while the molecular typing of EAEC and EPEC strains was more dispersed.cgMLST analysis further confirmed the genetic characteristics of different DEC strains.Conclusion DEC infections in Xiangshan County are mainly caused by EAEC,ETEC,and EPEC.These strains have abundant resistance genes.Among them,the molecular typing of EAEC and EPEC is relatively dispersed,while ETEC is concentrated in the clonal complex CC-10.

Traditional Chinese medicine(TCM)tongue diagnosis has obvious advantages,but its strong subjectivity,susceptibility to environmental influences,and lack of a unified standard greatly affect the objectivity and accuracy of diagnostic results,and it is difficult to integrate into the modern scientific system.Therefore,developing tongue diagnosis equipment to objectively and normatively extract tongue image information,and simulating human brain thinking to construct an objective diagnostic model of TCM tongue image-disease syndrome,and promoting the quantitative and intelligent research of TCM tongue diagnosis have become the trend of future development.This article reviews the research status and application prospects of TCM tongue diagnosis equipment,in order to provide methodological references and research ideas for the research and application of this field.

AIM To explore the clinical effects of Qutan Jiangni Pingchuan Formula combined with Compound Ipratropium Bromide on patients with acute exacerbation of chronic obstructive pulmonary disease.METHODS One hundred and ten patients were randomly assigned into control group(55 cases)for 2-week intervention of both Compound Ipratropium Bromide and conventional treatment,and observation group(55 cases)for 2-week intervention of Qutan Jiangni Pingchuan Formula,Compound Ipratropium Bromide and conventional treatment.The changes in clinical effects,relevant scores(TCM syndrome score,mMRC grade,CAT score),disappearance time for clinical symptoms(cough,wheezing,pulmonary wheeze),airway inflammatory indices(sICAM-1,IL-8,MCP-1),pulmonary function indices(FEV1,PEF25,TLC),sputum indices(24 h sputum volume,sputum viscosity)and incidence of adverse reactions were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05),along with shorter disappearance time for clinical symptoms(P＜0.05).After the treatment,the two groups displayed decreased relevant scores,airway inflammatory indices,24 h sputum volume(P＜0.05),and increased pulmonary function indices(P＜0.05),especially for the observation group(P＜0.05);the observation group demonstrated elevated number of people with grade Ⅰ sputum viscosity(P＜0.05),which was more obvious than that in the control group(P＜0.05).No significant difference in incidence of adverse reactions was found between the two groups(P＞0.05).CONCLUSION For the patients with acute exacerbation of chronic obstructive pulmonary disease,Qutan Jiangni Pingchuan Formula combined with Compound Ipratropium Bromide can safely and effectively improve clinical symptoms,reduce inflammatory levels,enhance lung functions,and promote sputum secretion in airways.
