OBJECTIVE To explore the value of bronchoalveolar lavage fluid(BALF)metagenomic next generation sequencing(mNGS)technique in diagnosis of the pulmonary cryptococcosis patients with different clinical features so as to raise the clinicians' awareness of the diagnosis of pulmonary cryptococcosis with BALF-mNGS.METHODS Totally 73 patients with pulmonary cryptococcosis and 73 non-pulmonary cryptococcosis patients who were treated in Wenzhou People's Hospital from Jan.2021 to May 2024 were recruited as the research subjects.The clinical data including baseline data,complications,clinical manifestations,clinical laboratory test data,ima-ging findings and serological test data were collected from the patients.The sensitivity and specificity of BALF-mNGS in diagnosis of the pulmonary cryptococcosis were observed,and the difference in the sensitivity in diagno-sis of the patients with various clinical features was analyzed.RESULTS A total of 73 patients with pulmonary cryp-tococcosis were enrolled in the study,44 of whom were male,and 29 were female;62 were positive for BALF-mNGS,11 were negative;all of the 73 non-pulmonary cryptococcosis patients were tested negative for BALF-mNGS,the sensi-tivity of the BALF-mNGS test was 84.93％,with the specificity 100.00％,the positive predictive value 100.00％,the negative predictive value 86.95％.Totally 45 patients had the symptoms of cough and expectoration,42 of whom were positive for BALF-mNGS,the test sensitivity of the patients with the symptoms of cough and expectoration was 93.33％,higher than that of the patients without the symptoms of cough and expectoration(P＜0.05).Totally 31 pa-tients had the lesion site of right lung,30 of whom were positive for BALF-mNGS,and the test sensitivity of the patients with lesion site of right lung was 96.77％,higher than that of the patients with the lesion site of left lung or both lungs(P＜0.05).Totally 44 patients had multiple lesions,41 of whom were positive for BALF-mNGS,the test sensitivity of the patients with multiple lesions was 93.18％,higher than that of the patients with single lesion(P＜0.05).CONCLUSIONS The sensitivity of the BALF-mNGS is high in diagnosis of the patients with pulmonary cryptococ-cosis,especially for the patients with symptoms of cough and expectoration,lesion site of right lung and multiple lesions.It can be used for the early diagnosis of pulmonary cryptococcosis.

To achieve the national objectives of improving medical quality and safety,the Shanghai Shenkang Hospital Development Center has formulated a list of major targets,tasks,and key results based onthe Objective and Key Results (OKR) method.The primary approaches adopted include establishing an organizational structure to advance medical quality and safety supervision,setting up a series of quantitative indicators for medical quality and safety targets,formulating standardized management systems,building an information platform,and strengthening supervision.It argues that the adoption of OKR can effectively promote the implementation of national target management for improving medical quality and safety,establish a cross-institutional management network for medical quality and safety,strengthen process management,and effectively drive continuous improvement in medical quality and safety.

Objective To explore the therapeutic effect of lower extremity exoskeleton robot(LEER)training on walking and balance function in patients with incomplete paraplegia.Methods According to the treatment method,70 patients with incomplete paraplegia were randomly divided into LEER group and control group,35 cases in each group.Both groups received regular rehabilitation therapy and functional walking training,and the LEER group received LEER training.Barthel index(BI),Berg balance scale(BBS)and functional ambulation category(FAC)were used to evaluate the activities of daily living,balance function and walking ability of the two groups before and 12 weeks after treatment.Results Compared with those before treatment,the BI and BBS scores of the LEER group and the control group were significantly increased(all P＜0.05).There was no significant difference in BI and BBS scores between the LEER group and the control group before treatment(all P＞0.05).The BI and BBS scores of the LEER group were significantly higher than those of the control group after treatment(all P＜0.05).There was no significant difference in FAC grade distribution between LEER group and control group before treatment(P＞0.05),and there was significant difference in FAC grade distribution between the two groups after treatment(P＜0.05).Conclusion LEER training can effectively improve the daily living ability,balance and walking function of patients with incomplete paraplegia,which is superior to the single intervention path of conventional rehabilitation training.

Adolescent idiopathic scoliosis(AIS)is a complex three-dimensional deformity involving coronal,sagittal,and axial planes,with a prevalence that should not be overlooked.With advancements in technology and in-depth research,an increasing number of hospitals and physicians are exploring standardized diagnostic and treatment approaches for AIS.Comprehensive and in-depth understanding is required for AIS,including its etiology,screening and diagnosis,classification,assessment and examination,treatment options,exploration of current focus,and evaluation of quality of life.Such understanding ensures that the diagnostic and treatment are scientific,standardized,and timely.Based on the principles of evidence-based medicine,a consensus on the diagnosis and treatment of AIS is reached after multiple discussions among spinal surgery experts,aiming to provide reference and guidance for clinical practice.

Objective To comparatively evaluate the diagnostic value of metagenomic next-generation sequencing(mNGS)versus conventional microbial culture in spinal infections.Methods A cross-section design was conducted on 82 consecutive patients with suspected spinal infections treated between February 2022 and January 2024 at Jiangbei Branch of First Affiliated Hospital of Army Medical University(Third Military Medical University).Microbiological culture,histopathological examination,and mNGS results from infected specimens were analyzed.Clinical diagnosis,primarily based on clinical manifestations,laboratory tests and radiologic features combined with medical history,was defined as the gold standard,and then the diagnostic performance,including sensitivity and specificity,were compared between mNGS and microbial culture.Results Among the 82 patients,definitive microbiological evidence was identified in 70 cases,and mNGS demonstrated a significantly higher detection rate than microbial culture(64 vs 36 cases,78.05％vs 43.9％,P<0.05).mNGS also obtained obviously higher sensitivity,accuracy,and negative predictive value(NPV),and notably lower positive predictive value(PPV)when compared to conventional microbial culture(all P<0.05).When stratified by infection type,mNGS obtained significantly higher sensitivity and accuracy compared to microbial culture in tuberculous spinal infections(P<0.05).For non-tuberculous spinal infections,mNGS also showed superior sensitivity to microbial culture(P<0.05).Conclusion In patients with spinal infections,mNGS demonstrates a significantly higher pathogen detection rate than conventional microbial culture.This technique can provide early and broad-spectrum pathogenic microbiological evidence for spinal infection.
