ArchiveIn the current development of acupuncture and moxibustion, there are problems such as traditional teaching methods, low efficiency, difficult quantification of technology and long training cycle of talents. This paper discusses the application value of virtual reality, augmented reality, mixed reality and biomechanical cross technology in acupuncture and moxibustion teaching and clinical practice, focusing on the analysis of acupuncture and moxibustion interactive power and application characteristic technology.
Selecting the relevant researches at home and abroad in recent ten years, the force feedback, characteristic technique and function realization of acupuncture auxiliary system were summarized and distinguished.
Virtual reality, augmented reality and mixed reality were closely combined with biomechanical feedback when applied to acupuncture assistance, and their respective technologies were focused on realizing functions such as acupuncture knowledge assisted memory, acupuncture point positioning, acupuncture training, etc., but there were some problems such as the limitation of edge computing power, insufficient precision of force feedback model, and insufficient functional integration.
Continuous optimization should be carried out in the direction of force feedback refinement, algorithm lightweight and multi-scene integration, and intelligent transformation of acupuncture and moxibustion teaching and clinical practice should be promoted by combining with large language model.
Physical rehabilitation training plays a crucial role in the recovery of hand function for patients after stroke. Currently, the hand rehabilitation training for stroke patients is mainly carried out by rehabilitation physicians. Hand rehabilitation robots can effectively alleviate the shortage of rehabilitation medical resources and reduce the workload of rehabilitation physicians. Their rehabilitation effects have been confirmed in clinical trials, but there is still room for improvement in terms of reliability and intelligence. This paper starts with the physiological structure of the human hand and the movement characteristics of the hand after stroke to introduce the rehabilitation needs of stroke patients. Then, it classifies the existing hand rehabilitation robots based on their structural forms and driving methods, elaborates on their application scenarios and features in detail, and summarizes typical control strategies and the evaluation standards for hand motor ability after stroke. Finally, it analyzes the existing problems of hand rehabilitation robots and looks forward to their development trends.
As a novel human-computer interaction paradigm that breaks through traditional neural pathways, the brain-computer interface (BCI) enables direct control of external devices by decoding central nervous system activities, demonstrating significant application value in the fields of neurorehabilitation and functional compensation. Functional near-infrared spectroscopy (fNIRS) detects changes in blood oxygen concentration in activated brain regions in real time, providing objective indicators of functional changes in the cerebral cortex. Therefore, the fNIRS-BCI technology, with its non-invasive nature, high spatiotemporal resolution, and strong resistance to motion interference, overcomes the limitations of traditional electroencephalogram (EEG) being easily affected by electromyographic artifacts, and has become a new monitoring tool in the field of neurorehabilitation. With algorithmic innovations and hardware iterations, its applications will expand from medical scenarios to education, entertainment, industry, and other fields. This article systematically expounds the current application status and challenges of the fNIRS-BCI technology system in areas such as motor rehabilitation, cognitive intervention, and communication for the severely ill, aiming to provide a theoretical framework for the clinical transformation of fNIRS-BCI technology in neurorehabilitation and suggest new development directions for personalized neural regulation and brain-peripheral coordinated rehabilitation.
The aim of this study is to provide technical support and reference basis for the research on the mechanism of cerebral small vessel hemorrhage and treatment methods through small animal Magnetic Resonance Imaging (MRI) sequences. This will facilitate in - depth exploration of the nature of the disease, optimization of treatment strategies, and promotion of the development of new treatment methods.
In this study, 5 C57 mice overexpressing the mutant sites of PIK3CA and MAP3K3 (p.I441M) were taken as the research objects. Imaging was carried out using different sequences of 7.0T small - animal nuclear magnetic resonance, such as T1WI, T2WI, SWI, DTI, and ASL. Parameter setting and image acquisition were performed, and the scanning results were statistically analyzed in terms of indicators such as the number of lesions, lesion area, and signal - to - noise ratio.
SWI shows excellent performance in the detection of the number, size, and signal - to - noise ratio of lesions (P<0.05). T2WI shows lesions more clearly than T1WI (P<0.05). DTI and ASL provide micro - structure and blood perfusion information respectively.
The comprehensive application of multiple sequences is helpful for a comprehensive assessment of pathological characteristics
To explore the influencing factors and action mechanisms of the tensile properties of rubber gloves, and provide a scientific basis for their design, production, and use.
Rubber glove samples from the same batch produced in June 2023 within the expiration date were selected. After cutting and conditioning, defective products were removed. According to the ISO 37 standard, type 2 dumbbell - shaped specimens were used. Multiple devices were employed, and methods such as contact extensometers and manual non - contact measurement were adopted. Three inspectors conducted independent tests, and one inspector carried out equipment comparison. Additionally, loose - clamping and pre - tension - clamping tests were performed with reference to relevant standards. Statistical analysis was conducted using
The initial test length error will lead to a deviation in elongation at break, such as a 2mm error resulting in an 11% deviation. The results of the holding method were higher than those of the manual method (P<0.05). The deviation of test data of different equipment was less than 5% (P>0.05). The 0.15N pretension can reduce the error, and the elongation at break is low when the loose clamping is 0.5N.
Factors such as the initial test length, measurement methods, equipment, and pre - tension significantly affect the tensile properties of rubber gloves. These factors need to be strictly controlled during production and inspection.

To investigate the value of cardiac magnetic resonance (CMR) multiparametric imaging in the localization, qualitative assessment, and staging diagnosis of coronary artery disease (CAD).
A retrospective analysis was conducted on 60 patients with suspected CAD who underwent both CMR and coronary angiography (CAG) at the Radiology Department of Huazhong Fuwai Cardiovascular Hospital between January 1, 2023, and February 28, 2025. Using CAG as the gold standard, the diagnostic performance of CMR in detecting myocardial ischemia/infarction was evaluated, and the consistency of CMR in staging CAD lesions was analyzed.
Among the 60 suspected patients, the CAG results showed 3 cases were negative and 57 cases were positive. Using CAG diagnostic results as the gold standard, the specificity, sensitivity, and accuracy of CMR diagnosis were all relatively high. Among the 57 confirmed patients, the agreement between CMR and CAG in detecting varying degrees of stenosis was slight (Kappa = 0.12), and the overall detection concordance rate of CMR for stenosis was relatively low, with particularly frequent missed diagnoses in mild/moderate stenosis. The left ventricular ejection fraction (LVEF) and cardiac output (CO) ranges in CMR diagnostic results were slightly lower than those of healthy adults, while the end-diastolic volume index (EDVI) range was slightly higher than that of healthy adults. Among the 57 confirmed patients, electrocardiogram (ECG) and CMR showed moderate to high agreement in myocardial infarction staging (Kappa ≈ 0.60).
In the diagnosis of suspected CAD, CMR provides indispensable functional and staging assessments, while CAG remains the gold standard for vascular anatomical evaluation. The combined application of CMR and CAG can enhance the diagnostic efficacy of CAD imaging.
To explore the effects of low-frequency pulsed electrical stimulation combined with betahistine injection on cochlear function and hemorheological indicators in patients with sudden sensorineural hearing loss (SSNHL).
A total of 102 patients with SSNHL admitted to the Department of Otorhinolaryngology of Liqun Hospital, Putuo District, Shanghai from January 2019 to January 2025 were selected and divided into a control group and an experimental group, each consisting of 51 patients, based on different treatment regimens. The control group was treated with betahistine injection, while the experimental group received low-frequency pulsed electrical stimulation in addition to the same treatment. The changes in cochlear function, hearing threshold gain, and hemorheological indicators [high shear rate blood viscosity (HSR-BV), low shear rate blood viscosity (LSR-BV), and plasma viscosity (PV)] before and after treatment were compared between the two groups.
After treatment, the hearing loss decibel number and pure tone air conduction hearing threshold value in the experimental group were lower than those before treatment and those in the control group at the same time, and the differences were statistically significant (P<0.05). The hearing threshold gain value in the experimental group was significantly higher than that in the control group, and the difference was statistically significant (P<0.05). The total effective rate of ABR test results in the experimental group was significantly higher than that in the control group, and the difference was statistically significant (P<0.05). After treatment, the PV, LSR-BV, and HSR-BV in the experimental group were lower than those before treatment and those in the control group at the same time, and the differences were statistically significant (P<0.05).
Low frequency pulse electrical stimulation combined with betahistine injection can play a significant synergistic role in the treatment of SSNHL, improving microcirculation, regulating hemorheology, enhancing neuroprotection, optimizing cochlear function, and improving hearing level.
To explore deep learning-based recognition and classification methods to address the cumbersome and time-consuming issues of traditional Alzheimer's disease (AD) detection and assessment, thereby improving diagnostic and predictive speed and accuracy.
MRI data were obtained from the Alzheimer's Disease Neuroimaging Initiative (ADNI). During preprocessing, MIPAV medical image processing software and 3D Slicer were used for AC-PC alignment, spatial normalization, skull stripping, and bias correction. The preprocessed data were converted into 5D tensors and input into a voxel residual network (VoxResNet) model in PyTorch for training. The training process employed L2 regularization, stochastic gradient descent (SGD) with momentum, and cross-entropy loss for optimization. Model performance was evaluated by analyzing the training loss, validation loss, and validation accuracy curves.
In binary classification tasks, the model performed exceptionally well, achieving a validation accuracy of 90.18% and an ROC-AUC value of 0.882, demonstrating strong discriminative ability between AD patients and cognitively normal individuals. However, in ternary classification tasks, the model exhibited lower validation accuracy, indicating underfitting.
The 3D VoxResNet-based MRI recognition method can provide valuable insights for early AD diagnosis and treatment.
To explore the feasibility of applying deep learning image reconstruction (DLIR) algorithm combined with low-dose contrast agent in abdominal enhanced CT Method 28 patients who needed upper abdominal enhanced CT scan due to their conditions were randomly divided into two groups, with 64 cases in each group. They underwent spectral CT abdominal enhanced examination with consistent scanning parameters. The conventional dose group was scanned with a contrast agent dosage of 1.5 ml/kg and reconstructed using the adaptive statistical iterative reconstruction (ASIR) algorithm, with an ASIR iteration rate of 60%. The low-dose group was scanned with a contrast agent dosage of 1.0 ml/kg and reconstructed using different levels of DLIR algorithms, including group A with medium-intensity deep learning image reconstruction (DLIR-M) and group B with high-intensity deep learning image reconstruction (DLIR-H).
evaluation indicators [noise, contrast-to-noise ratio (CNR), signal-to-noise ratio (SNR)] and subjective evaluation indicators (noise, overall image quality) were compared and analyzed among images reconstructed by different algorithms.
In objective evaluation, the noise of images in the conventional dose group, low-dose group A, and low-dose group B gradually decreased, and the differences between each pair of groups were statistically significant (P<0.05). The SNR of liver, SNR of pancreas, CNR of liver, and CNR of pancreas in the conventional dose group, low-dose group A, and low-dose group B gradually increased. There was no statistically significant difference between the conventional dose group and low-dose group A, but the differences among the other groups were statistically significant. In subjective evaluation, the subjective noise and overall image quality scores of the conventional dose group, low-dose group A, and low-dose group B were mostly above 4 points, which could meet the clinical diagnosis and treatment needs. The subjective noise scores gradually increased, and the differences between each pair of groups were statistically significant (P<0.05). In terms of subjective image quality scores, the score of low-dose group B was higher than that of low-dose group A and the conventional dose group, and the difference was statistically significant (P<0.05).
The image quality obtained by using DLIR algorithm combined with low-dose contrast agent is superior to that of ASIR algorithm combined with conventional dose contrast agent, and it can meet the needs of daily diagnosis. At the same time, it can reduce the required contrast agent dosage by about one-third.
To explore the application value of ultra-high-end computed tomography (GE 256-slice Revolution CT) urography in the diagnosis of urinary calculi.
A retrospective analysis was conducted on the clinical data of 156 patients with surgically confirmed urinary calculi admitted to a certain hospital from March 2021 to May 2024. All patients underwent abdominal plain films, B-ultrasound, and CT urography. The detection rates of X-ray positive and negative calculi by abdominal plain films, B-ultrasound, and CT urography were compared, and the diagnostic accuracy of Revolution CT urography for different types of urinary calculi was analyzed.
Compared with abdominal plain films and B-ultrasound, 256-slice Revolution CT urography had significantly higher detection rates of positive and negative calculi, with statistically significant differences (P<0.05). The diagnostic accuracy of Revolution CT urography for simple ureteral calculi, simple bladder calculi, simple renal calculi, ureteral calculi combined with renal calculi, and bladder calculi combined with ureteral calculi was higher than that of abdominal plain films and B-ultrasound, with statistically significant differences (P<0.05).
Compared with abdominal plain films and B-ultrasound, 256-slice Revolution CT has higher application value in the diagnosis of urinary calculi, which is conducive to further improving the diagnostic level and treatment effect of urinary calculi.

After treatment, the NTx level of the observation group was lower than that before treatment in the same group and that of the control group at the same time, and the BGP was higher than that before treatment in the same group and that of the control group at the same time, and the differences were statistically significant (P<0.05). After treatment, the scores of each item in the HSS scale of the observation group were higher than those before treatment in the same group and those of the control group at the same time, and the differences were statistically significant (P<0.05).
The application of CPM machine combined with traditional Chinese medicine fumigation and washing in the rehabilitation treatment of patients with knee stiffness after lower extremity fractures has a significant effect, which can effectively improve the range of motion of the knee joint, relieve pain, improve bone marker levels, and promote the recovery of knee joint function.
To explore the impact of different motion angle settings of the Continuous Passive Motion (CPM) device on the early recovery of knee joint function after Total Knee Arthroplasty (TKA).
A total of 90 patients who underwent unilateral TKA at Xuzhou Rehabilitation Hospital from January 2022 to December 2023 were selected and randomly divided into three groups: the small-angle group (n=30), the medium-angle group (n=30), and the large-angle group (n=30). The Visual Analogue Scale (VAS), Range of Motion (ROM), Knee Society Score (KSS), lower limb function score, and occurrence of complications were compared among the three groups at 3 days, 1 week, 2 weeks, and 4 weeks postoperatively.
On the 3rd day postoperatively, the VAS score of the small-angle group was significantly lower than that of the medium-angle group and the large-angle group (P<0.05). The ROM of the large-angle group was significantly higher than that of the medium-angle group and the small-angle group (P<0.05). At 1 week postoperatively, there was no significant difference in VAS scores among the three groups (P>0.05). The ROM of the large-angle group and the medium-angle group was significantly higher than that of the small-angle group (P<0.05). At 2 weeks and 4 weeks postoperatively, there were no significant differences in VAS scores and ROM among the three groups (P>0.05). At 4 weeks postoperatively, the KSS score and lower limb function score of the large-angle group and the medium-angle group were significantly higher than those of the small-angle group (P<0.05). The incidence of aggravated knee pain and swelling in the large-angle group was significantly higher than that in the medium-angle group and the small-angle group (P<0.05).
When using CPM for early rehabilitation training after TKA, setting the motion angle at a medium level (0°~60°) can effectively alleviate pain, promote the recovery of knee joint function, and reduce the occurrence of complications, making it the preferred angle range for early CPM rehabilitation training after TKA.
Renal vascular hypertension is in a continuous rising stage, which is common in middle-aged and elderly patients. Renal artery stenosis is the main cause of its disease. If it is not treated as soon as possible, it is prone to renal function injury, and even renal failure may occur. Timely assessment of renal artery stenosis is helpful for pre-treatment and prognosis evaluation of renovascular hypertension. There are many ways to evaluate renal artery imaging, such as ultrasound, digital subtraction angiography, CT angiography, contrast enhanced MR angiography, non contrast enhanced MR angiography, etc. Non contrast enhanced MR angiography has the advantages of multi parameter, multi angle, non-invasive, non radiation, no contrast injury, high-resolution imaging and so on. Compared with the commonly used methods of renal artery imaging evaluation, such as ultrasound and CT angiography, this article focuses on the research progress of different non contrast enhanced MR angiography techniques in the evaluation of renal artery stenosis.
To evaluate the effectiveness of mobile information systems in conducting initial risk assessments in orthopedic departments.
A total of 128 orthopedic patients treated in our hospital from February 2022 to February 2023 were selected and randomly assigned to two groups using a random number table method: a control group (n=64) and a study group (n=64). The control group utilized paper-based documentation for risk assessments and related nursing records, while the study group employed a mobile nursing information system for both risk assessment and nursing documentation. The primary outcomes measured were documentation time, error rates, and satisfaction levels among nursing staff and patients.
The study group demonstrated significantly shorter documentation time, lower error rates, and higher satisfaction levels among both nursing staff and patients compared to the control group (P<0.05).
The implementation of mobile information systems for initial risk assessments in orthopedic departments yields favorable outcomes. It not only reduces documentation time but also effectively minimizes errors, significantly enhancing the satisfaction of both nursing staff and patients. Therefore, this approach is recommended for widespread adoption in clinical practice.
The automation level of medical anesthesia machines is generally low. Therefore, this study independently developed an economical and practical fully automatic intelligent medical anesthesia machine. Based on the automatic regulation of fresh gas delivery requirements, a multi-channel switching gas path structure was designed. Through the electronic control system, intelligent fresh gas delivery and multiple mechanical ventilation modes can be achieved. The system also has an alarm function and a complete safety mechanism, and uses a touch screen for control parameter setting and patient status monitoring. The test results based on the GASMAN platform show that the system can achieve safe and effective anesthesia induction, with a maximum relative deviation of 8.86%. This design can effectively reduce the workload of anesthesiologists and the consumption of anesthetic drugs, and lay a solid foundation for more intelligent functions of anesthesia machines in the future, with significant application value.
