Objective To investigate the value of multimodal model integrating digital mammography(MG)and MRI radiomics features for preoperative prediction of lymphovascular invasion(LVI)status in breast cancer.Methods The clinical and imaging data from 336 patients with pathologically confirmed invasive breast cancer were retrospectively analyzed and randomly divided into a training group(235 cases)and a test group(101 cases)according to the ratio of 7∶3.Feature dimensionality reduction was carried out by Pearson correlation analysis followed by least absolute shrinkage and selection operator(LASSO)regression.Radiomics models were constructed based on MG craniocaudal(CC),dynamic contrast enhancement(DCE),T2 WI,and integrated MRI sequences;a multimodal model was further developed by incorporating clinical high-risk factors.The predictive efficiency of each model was evaluated by plotting receiver operating characteristic(ROC)curve.Results The ROC curve analysis showed that the multimodal model performed the best predictive efficiency,with area under the curve(AUC)of 0.989 and 0.861,accuracy of 0.949 and 0.782,sensitivity of 0.923 and 0.828,and specificity of 0.962 and 0.764 in the training group and test group respectively.Conclusion The multimodal model,integrating MG and MRI radiomics features,show optimal performance and can be served as a preoperative prediction of LVI status in breast cancer.

Hip fractures in the elderly are characterized by high incidence, high disability, and high mortality rates. Early, scientifically, and safe weight-bearing exercises are crucial for promoting functional recovery and reducing complications. Intelligent intervention is revolutionizing the field of rehabilitation through real-time monitoring, data-driven decision-making, and remote management, demonstrating particular potential in optimizing weight-bearing exercises. This paper systematically reviews the current application status of various types of intelligent interventions, such as real-time monitoring and feedback systems, intelligent rehabilitation assistance, and virtual reality technology in weight-bearing exercises for elderly hip fracture patients. This paper also analyzes their advantages in developing personalized rehabilitation plans, enabling precise monitoring and feedback, and preventing fall risks and explores challenges currently faced by intelligent interventions, such as device technical maturity, patient acceptance, economic costs, and data security. The purpose of this paper is to guide future technological optimization, clinical research, and policy support, thereby advancing the application of intelligent interventions in postoperative rehabilitation.

Objective To compare the impact of different primary tumor sites on the survival of patients with metastatic urothelial carcinoma(mUC)before and after the approval of immune checkpoints inhibitors(ICIs)based on data from Surveillance,Epidemiology,and End Results(SEER).Methods The mUC cases during 2013 and 2017 in the SEER database were enrolled.Cohorts were defined by primary tumor sites(renal pelvis,ureter,bladder)and then stratified by ICIs availability into non-ICIs era(2013)and ICIs era(2017).The survival differences in each cohort between the two eras were compared,and stratified analysis was performed.The 2-year overall survival(OS)was assessed using Kaplan-Meier analysis and multivariable Cox proportional hazards analysis.Results A total of 1750 mUC cases were enrolled,with 785 cases in the non-ICIs era and 965 in the ICIs era.No significant differences existed across different anatomical sites in the non-ICIs era,whether in the whole urinary system or inside bladder.The 2-year survival rates were 23.5％for ureteral cancer,18.0％for renal pelvic cancer,and 15.9％for bladder cancer.Significant prognostic disparities emerged among patients based on primary tumor sites in ICIs era(P＜0.05).The 2-year survival rates were 37.7％for ureteral cancer,25.5％for renal pelvic cancer,and 25.7％for bladder cancer.Further analysis revealed that the OS of the lesions originating from the bladder dome was significantly longer than that of the other bladder subgroups(P＜0.05),while the OS of the lesions in bladder bottom was the shortest.The 2-year survival rates were 52.0％for the bladder dome,13.0％for the bladder body,and 10.7％for the bladder bottom.Conclusion Our study indicates that in the non-ICIs era,there was no significant difference in the prognosis among mUC patients with lesions from different primary sites.In the ICIs era,the OS of ureteral cancer was significantly longer than that of bladder cancer and renal pelvis cancer.As for patients with metastatic bladder cancer,those with tumor located at the top of the bladder had a significantly better prognosis than those with tumors at other sites.

Objective To analyze the application effect of blunt dissection for myotomy of incision in single-port thoracoscopic lung wedge resection.Methods Patients who underwent single-port thoracoscopic lung wedge resection in our hospital from January to June 2024 were selected and divided into the observation group(32 cases,received blunt dissection for myotomy of incision during the surgery)and the control group(35 cases,received electrosurgical knife for myotomy of incision during the surgery)according to random number table method.The anesthesia time,operation time,intraoperative blood loss,the earliest time to get out of bed after the operation,the dosage of dezocine,and the resting and cough visual analogue scale(VAS)scores in each postoperative period of patients in the two groups were compared.Results There was no significant difference in terms of anesthesia time,operation time,intraoperative blood loss,or dosage of dezocine of patients between the two groups(P>0.05).The earliest time to get out of bed after operation of patients in the observation group was shorter than that in the control group,with significant difference(P<0.05).No significant difference was observed in resting VAS scores 6 hours or 12 hours after operation of patients in both two groups(P>0.05),but significant differences were found in resting VAS scores 24 hours and 48 hours after operation between the two groups(P<0.05).No significant difference was found in cough VAS scores 6 hours after operation of patients between the two groups(P>0.05),but significant differences were observed in cough VAS scores 12 hours,24 hours,and 48 hours after operation between the two groups(P<0.05).Conclusion Compared with electrosurgical knife for myotomy of incision,blunt dissection for myotomy of incision in single-port thoracoscopic lung wedge resection can reduce postoperative pain,promote postoperative ambulation for patients,which is beneficial to postoperative recovery.

Objective To explore the associations among smoking behavior,cognitive function,and personality traits in first-episode male patients with schizophrenia,thereby providing theoretical underpinnings for individualized treatment strategies in clinical settings.Methods A total of 140 first-episode male inpatients with schizophrenia admitted to the hospital from January 2022 to December 2023 were recruited.According to their smoking behavior,they were categorized into a smoking group(n=80)and a non-smoking group(n=60).Moreover,healthy controls were recruited and classified into a healthy smoking group(n=62)and a healthy non-smoking group(n=67)based on their smoking status.The Positive and Negative Syndrome Scale(PANSS)was employed to evaluate psychiatric symptoms in the schizophrenia groups.Nicotine dependence was measured using the Fagerstr?m Test for Nicotine Dependence(FTND)in the two smoking groups.Cognitive function and personality traits were assessed in all participants using the Repeatable Battery for the Assessment of Neuropsychological Status(RBANS)and the Eysenck Personality Questionnaire(EPQ),respectively.Results Regarding cognitive function,the smoking group among schizophrenia patients demonstrated significantly higher scores than the non-smoking group in immediate memory,attention,and delayed memory(all P<0.05).Among schizophrenia patients,FTND scores were moderately negatively correlated with attention and delayed memory(r=-0.552 and-0.657 respectively;both P<0.001).Concerning personality traits,smokers had significantly higher scores in neuroticism and psychoticism compared to non-smokers(both P<0.001).Both patient groups had significantly lower lie scale scores when contrasted with healthy controls(P<0.01),while the healthy smoking group showed significantly higher extraversion scores than the other groups.Conclusions The smoking behavior of male patients during their first episode of schizophrenia exhibits specific characteristics in relation to cognitive performance and personality traits.Smokers demonstrate relatively superior performance in cognitive domains including attention,immediate memory,and delayed memory.However,higher degrees of nicotine dependence are associated with poorer cognitive function,especially in the aspects of attention and delayed memory.Regarding personality,smoking patients display elevated levels of neuroticism and psychoticism.These findings indicate that smoking behavior may be closely associated with cognitive functioning and personality traits,thus meriting clinical attention in the management of schizophrenia.

AIM:To analyze the clinical value of predicting drug resistance in pulmonary tuberculo-sis patients based on improved machine learning models,and to build a visualization system for veri-fication.METHODS:Retrospectively selected 1 025 pulmonary tuberculosis patients hospitalized in Zhuhai Sixth People's Hospital from March 2019 to March 2024 with drug sensitivity test results as the research object.According to the definition of drug-resistant tuberculosis,the patients were divided in-to 631 sensitive groups(drug sensitivity test results showed no drug resistance),271 RR/MDR groups(meeting the definition of rifampicin resistant tu-berculosis or multi drug resistant tuberculosis,but no drug resistance to any kind of fluoroquino-lones),and 123 pre XDR groups(on the basis of multi drug resistant tuberculosis,and at the same time,drug resistance to any kind of fluoroquino-lones).Analyze clinical data based on the improved machine learning model,help build a drug resistant tuberculosis prediction model,synchronously com-plete feature screening,conduct value analysis on the screened features,and build a visual system for verification.RESULTS:Three groups of patients with baseline data comparison shows:Age,Body mass index(BMI),basic treatment of classification,lung diseases,haemoptysis,second-line drug use history,damage to lung,with empty in all statisti-cally significant difference between the three groups(P<0.05);Based on the modified ma-chine learning model,8 variables were screened,which were history of second-line drug use,BMI,treatment classification,destructive lung,underly-ing lung diseases,cavitation,hemoptysis,and age.The modified machine learning model had the high-est prediction accuracy compared with the tradi-tional model,with AUC values of 0.9322(RR/MDR prediction was positive class)and 0.9545(pre-XDR prediction was positive class).CONCLUSION:The application of the improved machine learning mod-el can help predict the occurrence of drug-resistant tuberculosis and assist the clinical formulation of more effective treatment plans.

[Objective] To explore the influencing factors of quality monitoring index on the nucleic acid pooling detection mode and continuously improve the detection quality of nucleic acid laboratory. [Methods] The quality monitoring indicators (NAT reactive rate, NAT resolution reactive rate, NAT invalid batch rate, NAT invalid result rate, equipment failure rate) and causes of invalidity in our laboratory from January 1, 2020 to December 31, 2022 were retrospectively analyzed. The quality monitoring indicators of the laboratory during 2020 to 2022 were compared longitudinally. The quality monitoring indicators of the laboratory in 2022 were compared horizontally with the overall level in Shandong for the same period to find the differences. [Results] From 2020 to 2022, a total of 218 686 samples were detected, the NAT reactive rate was 0.15‰ (32 samples in total), the resolution reactive rate was 39.02%, the invalid batch rate was 1.06%, the invalid result rate was 1.18%, and the equipment failure rate was 3.58%. There were no differences in the NAT reactive rate, NAT resolution reactive rate and NAT invalid batch rate among different years (P>0.05), but there were differences in the invalid result rate (P<0.05). Equipment failure was the main cause of invalid results (56.53%). Compared with other laboratories in Shandong, there were differences in the NAT reactive rate and invalid result rate (P<0.05). There were differences in the reaction rate, resolution rate and invalid result rate among different reagents (P<0.05). Compared with other two laboratories using the same manufacturer's reagent, there were differences in the reactive rate and invalid result rate (P<0.05), but no difference in the resolution rate and invalid batch rate (P>0.05). [Conclusion] Establishing quality indexes for process control and regular analysis can timely detect potential risks in laboratory operation. The use of quality indicators to implement self-comparison and inter-laboratory comparison can help the laboratory systematically and scientifically evaluate its own operating status and formulate corresponding quality management strategies, thereby improving the laboratory's testing capacity and ensure the safety of blood use.

This article systematically reviews the characteristics and trends of the writing, editing, publication and promotion of physiology textbooks in China from the late 19th century to the present, focusing on the introduction, development and innovation of Chinese physiology textbooks. The development of physiology textbooks in China is divided into four main stages: the introduction and initial development of physiology textbooks from the late 19th century to 1925; the localization and diversification of textbooks from 1926 to 1949, after the establishment of the Chinese Physiological Society; the exploratory phase of textbook construction after the founding of the People's Republic of China from 1949 to 1976; the formation and innovation of the textbook development process from 1977 to the present, following the restoration of the college entrance examination. For each phase, the article not only records the historical development of physiology textbooks, but also analyzes the evolution of their content, writing styles and the interaction with the social and political contexts. The article summarizes the characteristics and experiences of all these four phases. Special attention is given to the comprehensive statistical analysis of physiology textbooks published since the restoration of the college entrance examination and Economic Reform and Opening-up in 1977, revealing the changes in the number, publication trends and academic features of textbooks during this period. Finally, the article presets the future development of physiology textbooks in China, proposing that textbook writing should integrate aspects such as ideological and political education, medical humanities, basic and clinical medicine, health education, scientific research and international exchange and collaboration. The article also advocates for the application of new technologies and methods, such as artificial intelligence, virtual teaching models and knowledge graphs, to support "personalized learning". This research provides a systematic reference for the study of the history of medical education and offers theoretical support for the future innovation of physiology textbook in China.
