In recent years, cardiovascular disease has become a common disease. With the development of machine learning and big data technologies, the processing ability of electrocardiogram (ECG) signals has been greatly enhanced through new computer technologies, enabling the auxiliary diagnosis technology for cardiovascular disease (CVD) to achieve new improvements. This article discusses the application of machine learning in ECG processing, especially in the auxiliary diagnosis of diseases. Firstly, the conventional signal preprocessing methods are introduced, and then the EEG signal processing methods based on feature extraction and fuzzy classification are explored. Secondly, the application of auxiliary diagnosis in CVD is further summarized. Finally, the advantages and disadvantages of the two methods are analyzed, and based on this, a design of an auxiliary diagnostic system compatible with the two methods is proposed, providing a new perspective for similar applied researches in the future.

The conventional identification and prediction for failures of medical equipment mainly depend on experience and knowledge of manager for equipment,which are not able to be quantified and have lower efficiency. Therefore,it is obvious that the prediction for the failure of medical equipment is not accurate. With the technical development of computer and machine learning,the conventional identification and prediction that depend on experiences can deal with characteristics of failures through machine learning method to improve efficiency,which are hopeful in filling the gap of discipline about the identification and prediction for failures of medical equipment. This article summarized the application situation of machine learning in identifying and predicting failures of the medical equipment and the similarly electric equipment at home and abroad. Based on the key technique of identification and prediction,this article proposed suggestion about corresponding design architecture. According to the characteristics of the failure of medical equipment,this article summarized a series of information about algorithms of various machine learning in scene and accurate rate of identification and prediction,so as to provide references for relevant research of this field.

Objective:To reassess the prognostic value of minimal residual disease (MRD) and IKZF1 gene deletions in adults with B-cell acute lymphoblastic leukemia (B-ALL) who received pediatric-specific chemotherapy regimens during the Nanfang Hospital PDT-ALL-2016 trial.Methods:We retrospectively analyzed the prognosis of 149 adult patients with B-ALL who were admitted to Nanfang Hospital from January 2016 to September 2020. Prognostic factors were identified using Cox regression models.Results:The complete remission rate was 93.2% in 149 patients, with a 5-year overall survival (OS) rate of (54.3±5.0) % and a cumulative incidence of relapse (CIR) of (47.5±5.2) %. The Cox regression analysis revealed that MRD positivity at day 45 (MRD 3) after induction therapy was independently associated with relapse risk ( HR=2.535, 95% CI 1.122-5.728, P=0.025). Deletion of IKZF1 gene was independently associated with mortality risk ( HR=1.869, 95% CI 1.034-3.379, P=0.039). Based on MRD 3 and IKZF1 gene status, we categorized adult patients with B-ALL into the low-risk (MRD 3-negative and IKZF1 gene deletion-negative) and high-risk (MRD 3-positive and/or IKZF1 gene wild type) groups. The 5-year OS and CIR rates were (45.5±6.0) % vs (69.4±8.6) % ( P<0.001) and (61.6±8.3) % vs (25.5±6.5) % ( P<0.001), respectively, in the high-risk and low-risk groups, respectively. The multivariate analysis showed that the high-risk group was an independent risk factor for OS ( HR=3.937, 95% CI 1.975-7.850, P<0.001) and CIR ( HR=4.037, 95% CI 2.095-7.778, P<0.001) . Conclusion:The combined use of MRD and IKZF1 gene in prognostic stratification can improve clinical outcome prediction in adult patients with B-ALL, helping to guide their treatment.

Graves'ophthalmopathy(GO),also known as thyroid-associated ophthalmopathy,is an organ-specific au-toimmune disease that ranks first in the incidence of adult orbital diseases.GO has complex clinical manifestations,and dry eyes are a common cause of eye discomfort in patients with this disease.The pathogenesis of concurrent dry eyes is still unclear.It is currently believed that ocular surface damage in patients with GO is a direct factor leading to the occurrence and development of dry eyes.In addition,immunity and inflammation,and intestinal flora imbalance also play a role.Mul-tiple factors interact to form a vicious cycle,which further aggravates dry eyes.This article reviews the research results re-lated to the pathogenesis of GO complicated by dry eyes,aiming to provide ideas for clinical treatment and further research in the field.

Objective To evaluate the significant clinical value of an intelligent dispatching platform based on the 120 command system and provide the basis for improving emergency service efficiency. Methods Convenience sampling was used to choose 356 patients who received pre-hospital care in the Jiaxing Emergency Center from August 2023 to May 2024 as research objects. The 178 patients who made phone calls to the 120 center from August to December 2023 (namely before the establishment of intelligent dispatching platform) served as a control group,while another 178 cases who made phone calls to the 120 center from January to May 2024 (namely after the establishment of intelligent dispatching platform) served as an observation group. The optimal ambulance was chosen and sent to receive the patients by the dispatcher himself in the control group,while the intelligent dispatching platform designed by the research team and computer engineers was used in the observation group. The platform was made up of multimodal receipt of alarms,accurate location of phone call places,matching and dispatching of ambulance resources,and collaborative management functions within the region. At the same time,geographic information,hospital information,and emergency vehicle information were completed to achieve united dispatching and whole-process quality control all over the region. The emergency response time,2 minutes ambulance dispatching rate,coincidence rate of medical treatment principles,and success rate of cardiopulmonary resuscitation in cities and rural areas were compared between the control group (before the establishment of intelligent dispatching platform) and the observation group (after the establishment of intelligent dispatching platform). Results The emergency response time in the observation group after the establishment of intelligent dispatching platform was shorter than that in the control group in cities (minutes:8.64±0.99 vs. 10.57±1.00,P<0.05),while there was no statistical significance between the observation group and the control group in rural areas (minutes:11.66±1.49 vs. 11.94±1.70,P>0.05). The 2 minutes ambulance dispatching rate higher than those in the control group[99.44% (177/178) vs. 98.31% (175/178)],there was no statistical significance (P>0.05),the coincidence rate of medical treatment principles in the observation group were significantly higher than those in the control group[98.88% (176/178) vs. 89.89% (160/178),P<0.05],For the observation group,the success rate of cardiopulmonary resuscitation in the observation group was slightly higher than that in the control group[18.92% (7/37) vs. 13.51% (5/37)],but there was no statistical significance (P>0.05). Conclusion The construction of an intelligent dispatching platform with the function of united dispatching,collaborative management of resources,and whole-process quality control all over the region can improve emergency service efficiency and effectiveness,thus promoting the development of pre-hospital care course.
