Abstract Traditional Chinese medicine (TCM) auscultation has a long history, and with advancements in equipment and analytical methods, the quantitative analysis of auscultation parameters has determined. However, the complexity and diversity of auscultation, along with variations in devices, analytical methods, and applications, bring challenges to its standardization and deeper application. This review presents the advancements in auscultation equipment and systems, auscultation characteristic parameters, and their application in the diagnosis of pulmonary diseases and syndromes over the past 10 years, while also exploring the progress and challenges of current digital research of auscultation. This review also proposes the establishment of standardized protocols for the collection and analysis of auscultation data, the incorporation of advanced artificial intelligence (AI) auscultation analysis methods, and an exploration of the diagnostic utility of auscultatory features in pulmonary diseases and syndromes, so as to provide more precise decision support for intelligent diagnosis of pulmonary diseases and syndromes

Objective: To explore the feasibility of constructing a lung cancer early-warning risk model based on facial image features, providing novel insights into the early screening of lung cancer. Methods: This study included patients with pulmonary nodules diagnosed at the Physical Examination Center of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from November 1, 2019 to December 31, 2024, as well as patients with lung cancer diagnosed in the Oncology Departments of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine and Longhua Hospital during the same period. The facial image information of patients with pulmonary nodules and lung cancer was collected using the TFDA-1 tongue and facial diagnosis instrument, and the facial diagnosis features were extracted from it by deep learning technology. Statistical analysis was conducted on the objective facial diagnosis characteristics of the two groups of participants to explore the differences in their facial image characteristics, and the least absolute shrinkage and selection operator (LASSO) regression was used to screen the characteristic variables. Based on the screened feature variables, four machine learning methods: random forest, logistic regression, support vector machine (SVM), and gradient boosting decision tree (GBDT) were used to establish lung cancer classification models independently. Meanwhile, the model performance was evaluated by indicators such as sensitivity, specificity, F1 score, precision, accuracy, the area under the receiver operating characteristic (ROC) curve (AUC), and the area under the precision-recall curve (AP). Results: A total of 1 275 patients with pulmonary nodules and 1 623 patients with lung cancer were included in this study. After propensity score matching (PSM) to adjust for gender and age, 535 patients were finally included in the pulmonary nodule group and the lung cancer group, respectively. There were significant differences in multiple color space metrics (such as R, G, B, V, L, a, b, Cr, H, Y, and Cb) and texture metrics [such as gray-levcl co-occurrence matrix (GLCM)-contrast (CON) and GLCM-inverse different moment (IDM)] between the two groups of individuals with pulmonary nodules and lung cancer (P < 0.05). To construct a classification model, LASSO regression was used to select 63 key features from the initial 136 facial features. Based on this feature set, the SVM model demonstrated the best performance after 10-fold stratified cross-validation. The model achieved an average AUC of 0.8729 and average accuracy of 0.799 0 on the internal test set. Further validation on an independent test set confirmed the model’s robust performance (AUC = 0.823 3, accuracy = 0.729 0), indicating its good generalization ability. Feature importance analysis demonstrated that color space indicators and the whole/lip Cr components (including color-B-0, wholecolor-Cr, and lipcolor-Cr) were the core factors in the model’s classification decisions, while texture indicators [GLCM-angular second moment (ASM)_2, GLCM-IDM_1, GLCM-CON_1, GLCM-entropy (ENT)_2] played an important auxiliary role. Conclusion The facial image features of patients with lung cancer and pulmonary nodules show significant differences in color and texture characteristics in multiple areas. The various models constructed based on facial image features all demonstrate good performance, indicating that facial image features can serve as potential biomarkers for lung cancer risk prediction, providing a non-invasive and feasible new approach for early lung cancer screening.

ObjectiveBased on the new method of animal model evaluation， this paper summarized and analyzed the characteristics of traditional Chinese medicine（TCM） and Western medicine syndromes in existing autism spectrum disorder（ASD） animal models， and put forward suggestions for improvement. MethodRelevant literature on ASD animal models in China National Knowledge Infrastructure（CNKI） and PubMed were searched. According to the diagnostic standards of traditional Chinese and western medicine， core symptoms and accompanying symptoms were assigned values， and the clinical consistency of the models was comprehensively evaluated. ResultMost ASD model experimental animals were rodents， and the modeling methods included genetic and non-genetic. Domestic research focused on biochemical induction， while foreign research used genetic models more commonly. Among all models， valproic acid induction had the highest clinical consistency， followed by the neuroligin 4（NLGN4） and contactin associated protein like 2（CNTNAP2） gene knockout models. Most modeling methods could meet the characteristics of surface validity and structural validity， but did not clearly distinguish TCM syndromes. Currently， there is no model that has a high degree of clinical agreement between TCM and western medicine at the same time. ConclusionThe existing ASD animal models are mostly constructed under the guidance of western medicine， which lacks the characteristics of TCM syndromes. And the selection of evaluation indicators of western medicine is relatively single， without specifying the types of TCM syndromes. It is recommended to apply TCM intervention factors during the process of model preparation， to improve the evaluation indicators of traditional Chinese and western medicine， and to emphasize the study of on non-human primates， so as to lay a solid foundation for future experiments.

Objective To investigate the clinical effect and hearing loss of endolymphatic sac decompression(ESD)combined with one or two semicircular canal obstruction(SCO)in treating the patient with stage Ⅲ or stageⅣ Meniere disease.Methods Forty-three patients with stage Ⅲ or stage Ⅳ Meniere disease,who failed to respond to conventional conservative treatment and had the expectation of preserving residual hearing function,were enrolled in the study.They were divided into three groups according to the operation they underwent:ESD combined with lateral and posterior semicircular canal obstruction(ESD+LPSCO)13 cases,ESD combined with lateral semicircu-lar canal obstruction(ESD+LPSCO)14 cases,and ESD only 16 cases.Data of vertigo,ear fullness and tinnitus be-fore and after operation was collected,analyzed and compared.Hearing function before and after the operation was also evaluated.Results The number of vertigo attacks in the three groups(ESD+LPSCO,ESD+LSCO,and ESD)were all significantly reduced after operation.The vertigo control rate were 92.3％,78.6％and 62.5％re-spectively.Compared with pre-operation,the vertigo severity post-operation in the three groups were also signifi-cantly reduced.And the improvement rate of vertigo severity after ESD+LPSCO and ESD+LSCO were both 100％,which were significantly higher than that of ESD(68.8％).The discomfort of tinnitus and ear fullness in the three groups were significantly improved compared with that of pre-operation.The improvement rates of tinnitus in the three groups were 46.2％,50.0％and 43.8％respectively,with no significant difference.The improvement rate of ear fullness in the three groups were 61.5％,57.1％and 50.0％respectively,with no significant difference either.The proportion of patients with decreased hearing after operation in the three groups was 15.4％,7.1％and 18.8％,respectively,and the differences were insignificant.Conclusion ESD combined with one or two SCO can effectively control vertigo and other symptoms of patients with stage Ⅲ or Ⅳ Meniere's disease who had failure to conventional conservative treatment,and can preserve the residual hearing function in considerable extent.

ObjectiveTo investigate a suspected outbreak of carbapenem-resistant Acinetobacter baumannii （CRAB） nosocomial infection in an intensive care unit （ICU） and provide scientific evidence for prevention and control of multi-drug resistant nosocomial infection. MethodsClinical and epidemiological data of 4 patients with CRAB infection were retrospectively investigated in the ICU of Renji Hospital in November 2021. Environmental hygiene monitoring and multilocus sequence typing （MLST） were conducted and intervention measures were taken. ResultsA total of 4 cases with CRAB infection were identified， among which 1 case was determined to be community-acquired and3 cases were hospital-acquired. The isolated strains shared the same drug resistance， and were all classified into ST368 type. In the surface and hand samples （n=40）， 2 CRAB strains were detected in the air filter beside the bed of the first case， with a detection rate of 5%. After adopting comprehensive prevention and control strategies， including environmental cleaning and disinfection， hand hygiene， staff management and training， and supervision， no similar case with CRAB infection was found. ConclusionThis suspected outbreak of CRAB nosocomial infection may be induced by inadequate environmental cleaning and disinfection， and inadequate implementation of hand hygiene. Timely identification， investigation， and targeted measures remain crucial to effective control of possible nosocomial infection.

Objective To investigate the effectiveness and safety of endoscopic mucosal resection with precutting(EMR-P)for the treatment of rectal neuroendocrine neoplasm(RNEN)smaller than 1 cm in diameter.Methods Clinical data of 177 patients with RNEN smaller than 1 cm in diameter from December 2016 to December 2021 were retrospectively analyzed.According to different treatment protocols,177 patients with RNEN were divided into endoscopic mucosal resection(EMR)group(n = 46),EMR-P group(n = 40)and endoscopic submucosal dissection(ESD)group(n = 91).The en bloc resection rate,complete resection rate,operation time,postoperative hospitalization time and incidence of operative complications among the three groups were compared.Results The complete resection rate in the EMR-P group(95.0%)and ESD group(97.8%)were significantly higher than that in the EMR group(87.0%)(P<0.05);The operation time in the EMR-P group(9.86±2.23)min was longer than that in the EMR group(4.12±0.88)min,EMR-P group and EMR group were shorter than that in the ESD group(19.55±3.67)min,the difference was statistically significant(P<0.05);Postoperative hospitalization time in the EMR group was(2.45±0.29)d and EMR-P group was(2.43±0.23)d,which were shorter than that in the ESD group(3.30±0.32)d,and the difference was statistically significant(P<0.05).There were no significant difference in the rates of en bloc resection and operative complications among the three groups(P>0.05).Conclusion EMR-P for the treatment of RNEN<1 cm in diameter has the advantages,such as simple operation,short operation time and hospitalization time,high histological complete resection rate and low complication rate,which is worthy of clinical application.

Objective:To investigate the effect and potential mechanism of exposure to 20 nm polystyrene nanoplastics (PS-NPs) on lipid metabolism in mice liver.Methods:An animal experimental model was designed, which was completed from September 2022 to July 2023 on the exposure omics platform of the School of Public Health at Capital Medical University and the Key Laboratory of Environment and Population Health at the Chinese Center for Disease Control and Prevention.1 mg/kg and 10 mg/kg PS-NPs tail vein mice exposure models were constructed. After exposure 7 d, serum was collected to measure the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) and air flow assisted desorption electrospray ionization-mass spectrometry imaging (AFADESI-MSI) analysis were used to analyze the mRNA levels of fatty acid esterification related genes ( Dgat1 and Dgat2) and lipid transport related genes ( ApoB, Cd36, ApoE and Mttp) and metabolites′ spatial changes in liver tissue. In vivo imaging system (IVIS) and tissue shake sections were employed to observe the fluorescence biological distribution of PS-NPs. t-test or one-way ANOVA was used to explore the difference between groups. Results:The serum ALT levels were (83.97±4.58), (91.17±13.69) and (142.43±6.09) U/L in the control group, 1 mg/kg PS-NPs exposure group and 10 mg/kg PS-NPs exposure group respectively ( F=37.281, P<0.05). The relative mRNA levels of Dgat1, Dgat2, ApoB, Cd36 and ApoE were (1.49±0.63, 2.53±0.32, 2.45±0.54), (1.07±0.38, 1.86±0.83, 2.23±0.73), (1.01±0.13, 1.58±0.43, 2.03±0.52), (1.01±0.14, 1.55±0.37, 1.52±0.51), (1.01±0.17, 2.11±0.27, 2.39±0.93) in these three groups respectively. The differences were statistically significant ( F=11.54, 6.95, 14.90, 5.98 and 14.68, P<0.05). AFADESI-MSI analysis found that PS-NPs exposure led to a significant decrease in the levels of glutarylcarnitine and O-Linoleoylcarnitine ( t=4.12 and 3.35, P<0.05), which were associated with lipid beta oxidation. The content of triglycerides (TG) (m/z 921.726 4, t=8.69, P<0.05; m/z 919.711 4, t=3.20, P<0.05), phosphatidylic acid (PA) (m/z 895.712 3, t=3.60, P<0.05; m/z 821.526 6, t=3.36, P<0.05), lysophosphatidylcholine (LysoPC) (m/z 560.310 6, t=3.35, P<0.05; m/z 582.295 3, t=6.28, P<0.05), phosphatidylcholine (PC) (m/z 778.533 9, t=3.53, P<0.05; m/z 804.549 6, t=3.60, P<0.05; m/z 820.523 1, t=3.37, P<0.05), phosphatidylethanolamine (PE) (m/z 772.523 3, t=3.08, P<0.05) showed a significant increase in the PS-NPs exposure group. In vivo and in vitro imaging and in situ cell localization revealed that PS-NPs were mainly enriched in hepatic stellate cells and hepatic Kupffer cells in liver tissue. Conclusion:Exposure to PS-NPs induces disorder of liver lipid metabolism, which may be related to the accumulation of PS-NPs in hepatic stellate cells and hepatic Kupffer cells, providing basis for searching early biomarkers of PS-NPs exposure and further mechanism research.

Objective:To sort out the development context of precision nursing and compare and analyze the advantages and shortcomings in this field at home and abroad, so as to provide reference for the development of precision nursing in China.Methods:Through Web of Science core collection and CNKI database, literature related to precision nursing at home and abroad from January 1, 2012 to December 31, 2022 was retrieved. CiteSpace software was used to draw a scientific knowledge map for visualization analysis.Results:A total of 509 literatures in Chinese and 1 037 literatures in English were detected, and the annual number of publications showed a significant upward trend since 2015. The high-yielding institutions were mostly located in the United States, and the distribution of domestic institutions was relatively dispersed. From the perspective of research hotspots and frontiers, foreign research focused on health promotion and disease prevention research oriented by biological information, while Chinese research focused on individualized nursing research oriented by patient needs.Conclusions:In recent 10 years, the research of precision nursing in China has developed rapidly, but relatively speaking, the depth and breadth of its research still need to be improved. Chinese research should learn from the experience of foreign precision nursing practice and explore the mode of precision nursing that conforms to national conditions in China.

Objective:To systematically review the risk prediction model for vaginal delivery failure in low-risk primiparas, so as to provide reference for clinical practice and future research.Methods:Literature on the risk prediction model for vaginal delivery failure in low-risk primiparas was retrieved from China National Knowledge Infrastructure, WanFang Data, China Biology Medicine disc, PubMed, Embase, Cochrane Library, CINAHL, Web of Science and so on. The search period was from the establishment of the database to September 20, 2023. Two researchers independently screened literature, extracted data, and evaluated the risk of bias in the included studies.Results:A total of 10 articles were included, involving 14 models. Twelve models were constructed using Logistic regression, and the area under the receiver operating characteristic curve of the models ranged from 0.680 to 0.847. Common predictive factors of the model involved age of pregnant woman, height of pregnant woman, pre-pregnancy body mass index, gestational weight gain, gestational week, fetal birth weight, induction method, fetal biological measurements, and pre-delivery cervical Bishop score.Conclusions:The predictive performance of the vaginal delivery failure risk prediction model for low-risk primiparas is good, but the model construction method is relatively simple, and the overall bias risk is high. The model needs to be further optimized through machine learning, artificial intelligence, and other means, and extensively validated externally.

African swine fever(ASF),caused by the African swine fever virus(ASFV),is a highly contagious infectious disease of pigs.This disease has been spread rapidly in China since 2018,po-sing a huge threat to China's pig farming industry.To rapid detect the ASFV,a loop-mediated iso-thermal amplification(LAMP)combined with the disposable nucleic acid visualization test strip was established for visual detection of the nucleic acid of ASFV B646L gene.The method was easy to operate without special instruments and equipment,while it effectively avoided the disadvantage of false positives caused by aerosol contamination.The method was able to detect 1.16 copies/μL of the recombinant plasmid in 50 min at 65 ℃.In addition,the method was specific with no cross-re-action with classical swine fever virus,porcine reproductive and respiratory syndrome virus,por-cine parvovirus,transmissible gastroenteritis virus.The results in this study provides a rapid,con-venient,sensitive and reliable method for early diagnosis and screening for ASFV suspected infec-tion cases.
