This article systematically elucidates the current development status and future trends of robot-assisted surgery worldwide. Currently, robotic surgery led by the Da Vinci Surgical System has been widely adopted across multiple disciplines, including thoracic surgery, urology, and gynecology, demonstrating advantages such as precision, stability, and minimal invasiveness. Significant regional disparities exist in the global distribution of robotic surgery, reflecting inequalities in healthcare resources and economic development worldwide. China is rapidly emerging in the field of robotic surgery, undergoing a strategic transition from technology adoption to independent innovation: domestically developed systems (e.g., Toumai, Surgibot) have demonstrated safety and efficacy in multidisciplinary clinical practice; leveraging the advantages of 5G technology, remote robotic surgery has progressed from proof-of-concept to clinical reality, offering innovative solutions for equitable healthcare resource allocation; meanwhile, a quality control system spanning from national strategic planning to clinical operational standards is under development. Confronted with core challenges such as high costs, technical barriers (e.g., lack of force feedback), steep learning curves, lagging regulatory and ethical frameworks, and uneven regional development, future robotic surgery will deeply integrate artificial intelligence, evolving toward single-port/flexible miniaturization, normalization of remote surgery, and personalized precision treatment. Ultimately, it will drive the transformation of surgical medicine toward a new paradigm characterized by greater precision, intelligence, and accessibility, and is expected to play a strategic role in public health emergencies and disaster relief operations.

Objective To investigate the value of ultrasonographic features combined with immunohistochemistry in predicting axillary lymph node metastasis in middle-aged women with breast cancer.Methods A retrospective analysis was conducted on 827 middle-aged female breast cancer patients who underwent surgical treatment at the Affiliated Hospital of Chengde Medical University from June 2017 to June 2023.Ultrasonographic and immunohistochemical information was collected,and the patients were randomly allocated into a training set(579 patients)and a validation set(248 patients).Univariate and multivariate Logistic regression analyses were performed to identify ultrasonographic and immunohistochemical risk factors associated with axillary lymph node metastasis in these patients,and a nomogram model was developed.Receiver operating characteristic curves and calibration curves were established to evaluate the performance of the nomogram model,and clinical decision curves were built to assess the clinical value of the model.Results The maximum diameter,morphology,boundary,calcification,and expression of human epidermal growth facor receptor 2 and Ki-67 in breast cancer lesions were identified as risk factors for predicting axillary lymph node metastasis in middle-aged women.The areas under the curve of the nomogram model on the training and validation sets were 0.747(0.707-0.787)and 0.714(0.647-0.780),respectively.Calibration curves and clinical decision curves indicated good consistency and performance of the model.Conclusion The nomogram model constructed based on ultrasonographic features and immunohistochemistry of the primary breast cancer lesion demonstrates high value in predicting axillary lymph node metastasis in middle-aged women with breast cancer.

Objective:To observe the effects of tetrandrine tablets combined with montelukast sodium on respiratory function,inflammatory mediators,serum matrix metalloproteinase-9(MMP-9)and basic fibroblast growth factor(bFGF)levels in pneumoconiosis patients.Methods:120 pneumoconiosis patients who were admitted to our hospital from January 2023 to June 2024 were selected,they were divided into control group(montelukast sodium treatment,n=60)and study group(tetrandrine tablets combined with montelukast sodium treatment,n=60)by random number table method.The pulmonary function indexes[first second forced expiratory volume(FEV1),forced vital capacity(FVC),maximum ventilation volume(MVV)],6-minute walking test(6MWT)disitance,St.George Respiratory Questionnaire(SGRQ)score,Improved Medical Research Council Dyspnea(mMRC)index,and inflammatory mediators[Cystatin C(Cys C),interleukin-2 receptor(IL-2R),C-reactive protein(CRP)]and serum MMP-9,bFGF levels were compared between the two groups.The occurrence of adverse reactions were observed.Results:FEV1,FVC,MVV,6MWT distance in the study group at 6 months after treatment were higher than those in the control group,and SGRQ score,mMRC index,CysC,IL-2R,CRP,MMP-9,bFGF were lower than those in the control group(P＜0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion:Tetrandrine tablets combined with montelukast sodium in the treatment of pneumoconiosis patients can effectively improve respiratory function,increase exercise endurance,regulate inflammatory mediators and serum MMP-9,bFGF levels,which is safe and reliable.

This study analyzed the epidemiological characteristics of imported malaria in Yunnan Province from 2020 to 2023,to provide scientific evidence for formulating measures to decrease imported malaria and prevent re-establishment of malaria transmission.Malaria data reported by the China Disease Prevention and Control Information System were analyzed to determine parasite species;sources of infection;temporal,spatial,and population distributions;and importation routes.A total of 828 malaria cases were reported in the province.Plasmodium vivax and Plasmodium falciparum accounted for 89.98％and 8.33％of cases,respectively.A total of 47.58％of cases were imported from Myanmar,and all P.falciparum malaria ca-ses were from Africa.Thirteen(81.25％)prefectures or municipalities reported malaria,among which Dehong,Baoshan,Kunming,and Lincang reported 94.32％of cases.A total of 52.54％of cases were in young men.The proportion of cross-bor-der personnel flow,land input,and aircraft input were 88.89％and 11.11％respectively.A total of 98.19％of patients sought medical care within 7 days after fever onset,and 82.85％initiated diagnosis for malaria,and 84.90％of diagnoses were con-firmed by health facilities at or below the county level.Imported malaria is a major challenge in preventing re-establishment of transmission in Yunnan.Most imported cases involved cross-border malaria transmission of mainly Plasmodium vivax between China and Myanmar.To achieve malaria elimination,vigilance of health staff in malaria diagnosis and treatment should be pro-moted,and intensive malaria health education should be provided to people traveling to malaria endemic territories,to enable individual protection,and timely diagnosis and treatment after return from endemic countries.

TAFRO syndrome is a systemic inflammatory disease with unknown etiology.It has low incidence rate and progresses rapidly,which poses a significant challenge for clinicians to make a timely diagnosis and provide reasonable treatment.This article retrospectively analyzed a 65-year-old male patient with iMCD-TAFRO admitted to Minhang Hospital,Fudan University,and visited the Department of Nephrology due to bilateral lower limb edema.The patient exhibited systemic edema,fever,and multiple enlarged lymph nodes.A comprehensive examination showed thrombocytopenia,renal dysfunction,elevated CRP levels,multiple serosal fluid accumulations,and bone marrow reticulin fibrosis.For further diagnosis and treatment,he visited the Hematology Clinic of Zhongshan Hospital,Fudan University.Based on the clinical manifestations,the diagnosis of TAFRO syndrome was considered.After further lymph node pathological consultation,the diagnosis was confirmed as idiopathic multicentric Castleman disease(iMCD)-TAFRO syndrome.Later,the patient was transferred to the hematology department of Minhang Hospital,Fudan University.After 15 days of treatment with methylprednisolone,cyclosporine A,rituximab,and thrombopoietin,there was no significant improvement in the condition.Due to personal reasons,the patient discontinued further treatment and passed away 2 weeks later.

Objective To evaluate and compare the long-term efficacy of endoscopic radiofrequency ablation(RFA)and photodynamic therapy(PDT)combined with biliary stenting for the treatment of unresectable extrahepatic cholangiocarcinoma.Methods Clinical data of patients with cholangiocarcinoma who received endoscopic RFA or PDT treatment from February 2018 to February 2023 were retrospectively collected.The patients were divided into RFA group(n=30,received endoscopic RFA combined with biliary stent placement)and PDT group(n=20,received PDT combined with biliary stent placement).The frequency of treatment,stent patency time,overall survival time and adverse events incidence were counted.The factors affecting the survival time of patients were analyzed.Results The overall survival time was 14.0(95%CI:11.8～16.2)months in RFA group and 18.0(95%CI:15.4～20.6)months in PDT group,the median patency time of stent was 4.0(95%CI:2.7～5.3)months in RFA group and 3.5(95%CI:2.3～4.7)months in PDT group,the differences were not statistically significant(P>0.05).Multivariate Cox regression analysis showed that the H＾R of patients with≥2 endoscopic RFA or PDT treatments was 2.417,which was a protective factor affecting overall survival(P=0.018),while the H＾R of TNM stage Ⅲ to Ⅳ was 0.300,which was a risk factor affecting the overall survival period(P=0.002).No significant difference was found in clinical success rate(both 100.00%)and adverse events incidence between the two groups[28.13%(9/32)vs.23.81%(5/21)],the difference was not statistically significant(P>0.05).Conclusion The long-term efficacy of endoscopic RFA or PDT combined with biliary stenting in the treatment of unresectable extrahepatic cholangiocarcinoma is comparable,while the sequential treatment of endoscopic RFA or PDT≥2 times can effectively prolong the overall survival of patients.
