Moyamoya vasculopathy (MMV) refers to a chronic cerebrovascular disease characterized by progressive stenosis or occlusion of the arteries around the circle of Willis, accompanied by the formation of collateral vessels. In traditional Chinese medicine (TCM), MMV falls into the categories of “stroke”, “vertigo”, and “headache”, among others. Its core etiology is related to congenital insufficiency and acquired malnourishment, with wind, fire, phlegm, deficiency, and stasis as the key pathogenic factors. Current Western medical diagnosis and treatment of MMV remain suboptimal, and TCM pattern differentiation has yet to be standardized. The most common clinical patterns are liver yang hyperactivity (associated with hemorrhagic symptoms) and qi deficiency with blood stasis (associated with ischemic symptoms). Treatment modalities include acupuncture, Chinese herbal formulas, and TCM–Western medicine integrated therapy. Clinical trial results have confirmed that integrated therapy offers certain benefits for MMV; however, there is a lack of relevant diagnostic and treatment guidelines as well as in-depth mechanistic studies. This article reviews the progress in TCM and Western medicine for the diagnosis and treatment of MMV and proposes a trinity diagnostic and therapeutic approach integrating “disease differentiation–pattern differentiation–staging”, which provides a reference for TCM–Western medicine integration management.

Moyamoya disease (MMD) is characterized by progressive stenosis or occlusion of the distal internal carotid artery and its major branches, with secondary formation of abnormal collateral vessels at the skull base. Previous studies evaluated peripheral blood molecules to reflect vascular pathology and inflammation of MMD, but their limited specificity and susceptibility to confounding factors restricted clinical utility. With advances in high-throughput omics, blood-based biomarkers with improved specificity have been identified, and bioinformatics and machine learning have facilitated biomarker screening and diagnostic model development. Meanwhile, biomarkers for different clinical scenarios have emerged, promoting a shift from “diagnostic” to “decision-making” and “predictive” biomarkers. This review summarizes recent studies in blood-based biomarkers for MMD, aiming to provide references for future in-depth studies and clinical translation.

Objective: To analyze the whole genome characteristics of Salmonella in diarrhea cases in Hohhot City, so as to provide the evidence for the prevention and control of Salmonella infection and rational clinical use of antibiotics. Methods: Salmonella strains were isolated and identified from fecal specimens of acute diarrhea cases at sentinel hospitals for national foodborne disease surveillance in Hohhot City from 2021 to 2023. DNA was extracted for whole genome sequencing. Bioinformatics analysis based on the Microobench Pathogen Genome Analysis System was conducted to determine serotypes, multi-locus sequence typing (MLST), drug resistance genes, and virulence genes. Additionally, 60 Salmonella genomic sequences from different regions across China were downloaded from the NCBI Genome database. A phylogenetic tree was constructed based on core-genome MLST (cgMLST) to analyze the phylogenetic relationship between strains from Hohhot City and those from other regions of China. Results: From 2021 to 2023, a total of 42 Salmonella strains isolated in Hohhot City were classified into 12 serotypes. Salmonella Enteritidis ST11, Salmonella I 4,[5],12:i:- ST34, and Salmonella Typhimurium ST19 were identified as the dominant strains, represented by 13, 10, and 6 isolates, which accounted for 30.95%, 23.81%, and 14.29%, respectively. Seventy-seven drug resistance genes belonging to 12 classes were detected. Among them, 17 Salmonella strains carried amino acid substitutions in the fluoroquinolone resistance-determining region caused by mutations at the gyrA and parC loci. Virulence genes covered all stages of Salmonella pathogenesis, with a predominance of genes associated with adhesion. Phylogenetic tree analysis results revealed that the 42 Salmonella strains from Hohhot City were distributed across evolutionary branches A, B, C, D, and F. They clustered with 60 strains from other regions of China, suggesting potential cross-regional transmission. Conclusions Salmonella strains isolated in Hohhot City exhibited diverse serotypes, carried multiple drug resistance genes and virulence genes, and displayed high genetic diversity. These findings indicate a potential risk of cross-regional transmission, highlighting the need for enhanced surveillance and prevention measures.

Under the background of breaking the " five only" evaluation criteria, continuously optimizing the scientific research performance evaluation system of hospitals to mobilize the enthusiasm and creativity of scientific researchers and guide the direction of scientific research development plays an important role in enhancing the overall scientific research capability of hospitals. Through literature analysis and expert consultation, a certain hospital has constructed a personal scientific research performance evaluation index system for medical staff in tertiary public hospitals, oriented towards innovation quality and member contributions, and began to implement it throughout the hospital in 2021. This index system included four categories of scientific research performance: vertical scientific research projects, academic influence, science and technology awards, and transformation of achievements, with a total of 20 indicators. The annual scientific research performance score of an individual would serve as the basis for the distribution of year-end scientific research performance and an important reference for applying for key and major projects within the hospital. After the application of this evaluation index system, the enthusiasm of medical staff for scientific research has been effectively stimulated. The average individual scientific research performance score increased from 0.974 in 2020 to 1.220 in 2023. All scientific research indicators involved in the evaluation system have shown growth, with a significant increase in high-quality results. This evaluation system can provide a reference for the scientific research performance evaluation of public hospitals under the background of breaking the " five only" evaluation criteria.

Objective:To explore the correlation between the oxygenation index and the monitored parameters of lung injury view in ventilator,so as to provide a basis for monitoring the change of oxygenation index by the parameters of lung injury view.Methods:A total of 28 patients who received mechanical ventilation treatment and admitted to respiratory department of the First Affiliated Hospital with Nanjing Medical University from May 14 to September 30,2024 were selected.The monitored parameters of lung injury views of them during mechanical ventilation treatment with invasive ventilators were collected,including platform pressure(Pplat),driving pressure(ΔP),mechanical energy(Emech),ratio of tidal volume to ideal body weight(TVe/IBW),etc..Then,the data of oxygenation index were obtained.Finally,135 valid data were screened out.The 84 pieces of data with oxygenation index≤300mmHg were included in low oxygen group,and 51 data with oxygenation index>300mmHg were included in normal group.The correlations between oxygenation index and Pplat,ΔP,Emech,TVe/IBW were conducted by pairwise analysis.Results:In the low oxygen group,the oxygenation index was[(196.302±74.522)mmHg]significantly negative correlation with Emech[(12.686±5.401)J/min](ρ=-0.425,P<0.05),but not was significant correlation with Pplat,ΔP,and TVe/IBW(P>0.05).In the normal group,there were not significant correlations between the oxygenation index and Pplat,ΔP,Emech and TVe/IBW(P>0.05).There was a significant negative correlation between Emech and rank of oxygenation index(β=-0.389,P<0.05)in the low oxygen group.Conclusion:The visualization function of the Emech of the monitored parameters in lung injury view of ventilator can provide help for monitoring the changes of oxygenation index of patients in the low oxygen group,and can improve the oxygenation of patients by optimizing mechanical energy.However,it is necessary to balance the contradiction between ventilation intensity and protection for lung.

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 investigate the selection strategy for recipient vessels in free flap reconstruction of head and neck defects.METHODS A retrospective analysis was conducted on 96 patients who underwent 99 free flap reconstructions for head and neck defects between January 2020 and December 2024.Recipient vessel selection,flap survival,and postoperative complications were analyzed based on defect location and flap type.RESULTS In 99 cases microvessel anastomosis,the recipient arteries were superior thyroid artery in 49 branches,facial artery in 28 branches,superficial temporal artery in 14 branches,lingual artery in 5 branches.external carotid artery in 1 branch,transverse cervical artery in 1 branch,and superior laryngeal artery in 1 branch.Venous anastomosis was performed in 104 branches,with 94 cases in 1 venous anastomosis and 5 cases in 2 venous anastomoses.The recipient veins selected were facial vein in 62 branches,external jugular vein in 21 branches,superficial temporal vein in 12 branches,retromandibular vein in 3 branches,middle thyroid vein in 2 branches,internal jugular vein in 2 branches,middle temporal vein in 1 branch,and superior thyroid vein in 1 branch.Complete flap necrosis occurred in 5 cases,and partial necrosis occurred in 4 cases.When the recipient vessels were deficient,the lingual artery was chosen in 3 cases,the facial artery in 1 case,the external jugular vein in 3 cases,the internal jugular vein with end-to-side anastomosis in 1 case,and the common facial vein with end-to-side anastomosis in 1 case.CONCLUSION In free flap reconstruction for head and neck defects,the superior thyroid artery,facial artery,and superficial temporal artery are commonly used as recipient arteries,while the facial vein,external jugular vein,and superficial temporal vein are frequently selected as recipient veins.When recipient vessels are scarce,the ipsilateral lingual artery,transverse cervical artery,and main trunk of the internal jugular vein can serve as alternative recipient vessels.

Objective:To explore more objective detection method for the performance of diagnostic equipment with ultrasound,so as to demonstrate that the subjectivity of the interpretation criteria will affect the results of resolution parameters of detection performance of ultrasonic equipment.Methods:A total of 77 conventional probes of 33 ultrasound equipment of Jiangsu Provincial Hospital were collected and sorted out.The resolution parameters of their performance were tested twice from 2022 to 2023 by the technical personnel of our institute and the tester of Jiangsu Institute of Metrology.The data was described by using the quartiles method.The resolution parameters of performances of ultrasound equipment and probes were paired to conduct Wilcoxon rank sum test,so as to compare the differences in same institute between different years,and in same year between different institute in testing the resolution parameters of performances of ultrasound equipment and probes.Results:For linear array probes,as long as the performance was tested in accordance with the standard method,there was no statistically significant difference in the resolution parameters measured between different institutes and between different times(P>0.05).For the convex array probe,in 2023,the lateral resolution[2(2,2)]of the 70mm target group,and the axial and lateral resolutions[1(1,1)and 3(3,3.25)]of the 120mm target group of our institute were different with the lateral resolution[2(1,2)]of the 70mm target group,and the axial and lateral resolutions[2(2,3)and 2(2,3)]of the 120mm target group of Jiangsu Institute of Metrology,and the differences of them between our institute and Jiangsu Institute of Metrology were significant(Z=-2.887,-2.53,-3.69,P<0.05),respectively.In our institute,the axial and lateral resolutions[1(1,2)and 2.5(2,3)]of the 70mm target group,and the axial resolution[1(1,2)]of the 120mm target group in 2022 were different with the axial and lateral resolutions[1(1,1)and 2(2,2)]of the 70mm target group,and the axial resolution[1(1,1)]of the 120mm target group in 2023,and the differences of them between two years were significant(Z=-3.317,-3.419,-2.982,P<0.05).In Jiangsu Institute of Metrology,the lateral resolutions of the 70mm target group,and the axial resolution[1(1,1)]of the 120mm target group in 2022 year were different with those in 2023 year,and the differences of them were significant(Z=-2.333,-3.051,P<0.05),respectively.Conclusion:The interpretation for lateral resolution of convex array probe in target group with high depth,the difference of subjective interpretation criteria will cause the essential difference of final results.This paper suggested that the key image should be retained when the resolution of the image of target group with high depth of the convex array probe is interpreted.At the later stage,artificial intelligence(AI)-assisted quality control can also be introduced to conduct objective interpretation by computers.

Objective To observe the functional connectivity and glucose metabolism of insular subregions in behavior variant of frontotemporal dementia(bvFTD)patients,also their correlations with cognitive function.Methods Thirty-eight bvFTD patients(bvFTD group)and 44 healthy individuals(control group)were retrospectively enrolled.The average time series signals of insular subregions were extracted as seed points based on functional MRI(fMRI)and 18F-FDG PET,then whole brain functional connectivity map was obtained.Meanwhile,the pons was selected as the reference brain region,and the standard uptake value ratio(SUVR)of insular subregions were calculated.The above parameters were compared between groups,and the correlations of SUVR of insular subregions with clinical cognitive function scale scores in bvFTD group were analyzed.Results Compared with control group,the functional connections between all insular subregions and bilateral frontal lobe,temporal lobe,anterior cingulate gyrus,anterior cingulate gyrus and middle cingulate gyrus,as well as between some subregions and bilateral parietal and occipital lobes were weakened in bvFTD group(GRF correction,voxel level all P＜0.001,cluster level all P＜0.05).SUVR of all insular subregions significantly decreased(GRF correction,voxel level all P＜0.001,cluster level all P＜0.05),which in right ventral agranular insula(vIa),dorsal agranular insula(dIa),dorsal dysgranular insula(dId)and left dorsal agranular insula(dIa)were negatively correlated with frontal behavioral inventory(FBI)score in bvFTD group(r=-0.452--0.330,all P＜0.05).Conclusion In bvFTD patients,the functional connectivity and glucose metabolism of insular subregions changed,and SUVR of right vIa,dIa,dId and left dIa were negatively correlated with FBI score.

The transformation of medical models and the growing demand for healthcare necessitate the establishment of one-stop multimorbidity management clinics within general practice departments of general hospitals to enhance clinical management of patients with multiple chronic conditions. This study employed SWOT analysis to evaluate the internal conditions (strengths and weaknesses) and external conditions (opportunities and threats) associated with establishing such clinics. The analysis revealed that the strengths of general practice departments in general hospitals for establishing a multimorbidity clinic include abundant medical resources, the comprehensive nature of general practice functions, and multidisciplinary collaboration. Opportunities are presented by public health needs, supportive government policies, and technological advancements. However, weaknesses include shortages of qualified human resources, the high complexity of patient management, increased medical costs, limitations in insurance reimbursement, and difficulties in performance evaluation. Threats encompass an underdeveloped general practitioner system, patients′ traditional healthcare-seeking habits, medico-legal and ethical challenges, and a lack of directly transferable experience. Based on this analysis, the paper proposes strategies and measures for developing multimorbidity clinics within general practice departments of general hospitals in China, aiming to provide a theoretical foundation for their promotion and development.
