The solutions of the governing field equations are given in both Cartesian and cylindrical coordinates. The expressions derived in this paper can be used conveniently for optimal design of machine. The computed results using the proposed 2D analytical method are validated by the more accurate, though a lot more complicated, 3D finite element analyses.展开更多

In the analysis the permanent magnets are taken as magnetic charges. Hexahedron element meshes are automatically generated by a prc-proccssing program developed by the authors. The flux densily is computed by a 3D scalar potential method program. Based on the linite elcment analysis the induced emf, current, armaturc reaction effects and electromagnetic torque of the disc machine are all calculated.展开更多

Methods: A 26-year-old female patient was diagnosed with type II ODV with macular edema (ME). The information was obtained by complete medical and ophthalmic history taking and a detailed ophthalmic examination at the initial and follow-up visits. Functional and morphological outcomes at baseline, 1 week and 1 month following IVR+SS injections, are presented. Results: Best-corrected visual acuity (BCVA) improved from 78 letters (ETDRS) at baseline to 90 letters at 1-week follow-up and maintained stable through 1-month follow-up. Central retinal thickness (CRT) measured by optical coherence tomography (OCT) decreased from 465 μm at baseline to 240 μm at 1-week follow-up and to 226 μm at 1-month follow-up. Mean deviation (MD) measured by perimetry increased from ?5.17 dB to ?4.59 dB and to ?4.29 dB, respectively. Fluorescein angiography (FFA) showed that the initial macular edema at baseline disappeared while the arm-retina circulation time (ART) was also greatly shortened when compared to the baseline. Electroretinogram (ERG) measured at 1-month follow-up demonstrated an overall improvement of the retinal function after the injection. No ocular or systemic side effects were detected. Conclusions: IVR+SS injection may lead to resolution of the associated ME and improve the retina morphologically as well as functionally. To our knowledge, this is the first case of a type II ODV benefiting from treatment with IVR+SS injection. The observed results warrant further investigation.展开更多

Methods: in this study, 122 elderly patients with blood stasis type of lumbar disc herniation admitted from November 2020 to February 2022 were selected as the research objects to observe their therapeutic effects. In this experiment, 61 patients were selected as group X and traction therapy was used for the related experiment. More than 61 patients were selected as the control group of group X, and based on group X, clinical treatment was carried out by combining massage with acupuncture. When the selected two groups of patients are tested by different methods, the doctors should compare the curative effect and joint movement of the two groups of patients. At the same time, doctors should also pay attention to patients with other diseases, to ensure that the patients spirit and communication ability are normal. Before conducting the study, doctors should take the initiative to explain the content and purpose of the study to the patients. Only when the patients know and agree can the results of the study be announced to the public. Results: the above methods were used to analyze these patients, and it was found that both methods can effectively treat lumbar disc herniation with blood stasis. Considering the final therapeutic effect, the therapeutic effect of the combination of these two methods is better than that of traction therapy alone. In addition, the patients joint activity has also been significantly improved with massage and acupuncture. In the questionnaire, the patients are satisfied with the combination therapy. The results of the two groups are also very different, which can be used as the basis of this study. Conclusion: according to the above research findings, acupuncture, massage, traction and other methods of traditional Chinese medicine can effectively improve the pain of patients and improve the quality of life of patients. Therefore, when treating it, we should actively recommend and adopt the combination therapy to improve the patients satisfaction with the curative effect, which is to achieve the curative effect in the shortest time.展开更多

Objective: The purpose of this study is to provide high-quality evidence to support the effectiveness of the traditional Chinese hot and humid compress in the treatment of LDH with qi stagnation and blood stasis. Methods: From October 2021 to November 2023, 86 patients with LDH of qi stagnation and blood stasis type were recruited in our hospital and divided into a control (n = 43) and an observation group (n = 43) according to the random number table method. The control group was given routine clinical treatment, and the observation group was treated with the hot and humid compress therapy for two weeks. The visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score, TCM syndrome score, serum interleukin-6 (IL-6), serum interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) were observed and compared between the two groups before and after treatment, and the clinical efficacy of the two groups was evaluated. Results: After treatment, the VAS score, TCM symptom score, and serum IL-6, IL-1β, and TNF-α levels decreased in both groups (P P P P P Conclusions: The hot and humid compress of traditional Chinese medicine can effectively relieve pain, restore lumbar function, improve TCM syndromes, reduce the level of inflammatory factors, and have a curative effect in treating LDH.展开更多
