Transcutaneous electrical stimulation equipment is a kind of characteristic therapeutic devices developed on the basis of the integration of traditional Chinese medicine (TCM) theory and modern science and technology, which is widely used in clinical practice. Significant breakthroughs have been made in the development of related devices such as transcutaneous electrical acupoint stimulation (TEAS) devices, transcutaneous electrical nerve stimulation (TENS) devices, and transcutaneous auricular vagus nerve stimulation (taVNS) devices in recent years. Although the market for these devices is vast, there are still limitations that need to be optimized in terms of electrode materials and power supply methods, bulky instrument size, cumbersome wiring, restricted applications, and inadequate intelligent functionality. In the future, it is still necessary to further build upon the theoretical foundation of TCM acupuncture, integrate a variety of modern scientific technologies to advance the intelligence and modernization of acupuncture equipment, and thereby improving its capabilities to support clinical practice and research.

After being treated with acupuncture, some patients with idiopathic tinnitus may experience a short-term aggravation of tinnitus symptoms on the original basis. These symptoms can be gradually relieved and the overall condition fluctuates towards recovery. This phenomenon has brought some difficulties to patients and clinicians. Based on the academic view of TCM, "destroying pathogens and re-building balance", and in association with the existing understanding of acupuncture in modern medicine for tinnitus, this paper briefly discusses the mechanism and influencing factors of symptom fluctuation in patients with idiopathic tinnitus after acupuncture treatment in terms of both TCM and modern medicine, and proposes the future direction in the research of symptom fluctuation, so as to promote the recognition of clinicians and patients on symptom fluctuation and make rational use of its positive effects. Besides, it is hoped that more researchers will pay attention to symptom fluctuation and advance the exploration of it in academic field.

Background The number of persons with thyroid nodules has increased rapidly in recent years, and thyroid cancer caused by malignant nodules has become a key problem endangering the health of young and middle-aged groups in China. Objective To explore work and lifestyle influencing factors for developing thyroid cancer among young and middle-aged patients with thyroid nodules. Methods The subjects with thyroid nodules were reported by routine physical examines ordered at the Huadong Sanatorium. We conducted a 1∶4 matched case-control study in which 232 patients diagnosed with thyroid cancer from 2012 to 2022 were matched to 928 controls by gender and age (±5 years). A validated questionnaire was used to collect data on work and lifestyle behaviors. Univariate and multivariate logistic regression models were applied to explore potential relationships between selected factors (including environment, working hours, stress, diet, exercise, and mental health) and thyroid cancer. Spearman rank correlation was used to analyze the correlations between variables. Results The results of univariate logistic regression showed a history of thyroid cancer reported among first-degree relatives (OR=6.059, 95%CI: 1.007, 36.473), obesity (OR=1.973, 95%CI: 1.296, 3.004), noise and vibration exposure (OR=1.988, 95%CI: 1.143, 3.456), frequent stress (OR=2.093, 95%CI: 1.231, 3.559), frequent depression (OR=2.034, 95%CI: 1.048, 3.947), frequent anger (OR=1.791, 95%CI: 1.066, 3.012), frequent fried food diet (OR=1.535, 95%CI: 1.026, 2.297), and frequent fast food diet (OR=1.836, 95%CI: 1.048, 3.215) were risk factors for reporting thyroid cancer developing from thyroid nodules, while regular meals (OR=0.245, 95%CI: 0.061, 0.989) and frequent exercise (OR=0.571, 95%CI: 0.342, 0.952) were protective factors for reporting no thyroid cancer. The results of Spearman correlation analysis showed that body mass index was positively correlated with frequent fried food, fast food, and sugary beverage diets (r=0.123, 0.083, 0.077, P<0.01), and negatively correlated with frequent depression and anger (r=−0.090, −0.070, P<0.05). The results of multiple logistic regression found that a history of thyroid cancer reported among first-degree relatives (OR=6.712, 95%CI: 1.071, 42.066), obesity (OR=2.032, 95%CI: 1.321, 3.125), noise and vibration exposure (OR=1.991, 95%CI: 1.089, 3.637), and frequent stress (OR=2.468, 95%CI: 1.417, 4.300) were associated with an elevated risk of reporting thyroid cancer developing from thyroid nodules patients. Regular exercise (frequency≥3 times·week⁻¹, > 30 min per episode) (OR=0.516, 95%CI: 0.300, 0.890) was associated with a lowered risk of reporting thyroid cancer. Conclusions Multiple risk factors associated with reporting thyroid cancer among young and middle-aged groups with thyroid nodules are identified, such as obesity, noise and vibration exposure, frequent stress, and lack of exercise.

OBJECTIVE: To evaluate the operability and effectiveness of a self-developed patellar bone canal locator (hereinafter referred to as "locator") in the reconstruction of the medial patellofemoral ligament (MPFL). METHODS: A total of 38 patients with recurrent patellar dislocation who met the selection criteria admitted between January 2022 and December 2022 were randomly divided into study group (the patellar canal was established with a locator during MPFL reconstruction) and control group (no locator was used in MPFL reconstruction), with 19 cases in each group. There was no significant difference in baseline data between the two groups ( P>0.05), such as gender, age, body mass index, disease duration, patella Wiberg classification, constituent ratio of cartilage injury, Caton index, tibia tubercle-trochlear groove, and preoperative Lysholm score, Kujal score, Tegner score, visual analogue scale (VAS) score, and so on. The Lysholm score, Kujal score, Tegner score, and VAS score were used to evaluate knee joint function before operation and at 3 days,1 month, 3 months, and 6 months after operation. The ideal prepatellar cortical thickness and canal length were measured before operation, and the actual prepatellar cortical thickness and canal length after operation were also measured, and D1 (the distance between the ideal entrance and the actual entrance), D2 (the ideal canal length minus the actual canal length), D3 (the ideal prepatellar cortical thickness minus the actual prepatellar cortical thickness) were calculated. RESULTS: Patients in both groups were followed up 6-8 months (mean, 6.7 months). The incision length and intraoperative blood loss in the study group were smaller than those in the control group, but the operation time was longer than that in the control group, the differences were significant ( P<0.05). There was no complication such as incision infection, effusion, and delayed healing in both groups, and no further dislocation occurred during follow-up. One patient in the study group had persistent pain in the anserine area after operation, and the symptoms were relieved after physiotherapy. The VAS score of the two groups increased significantly at 3 days after operation, and gradually decreased with the extension of time; the change trends of Lysholm score, Kujal score, and Tegner score were opposite to VAS score. Except that the Lysholm score and Kujal score of the study group were higher than those of the control group at 3 days after operation, and the VAS score of the study group was lower than that of the control group at 3 days and 1 month after operation, the differences were significant ( P<0.05), there was no significant difference in the scores between the two groups at other time points ( P>0.05). Patellar bone canal evaluation showed that there was no significant difference in preoperative simulated ideal canal length, prepatellar cortical thickness, and postoperative actual canal length between the two groups ( P>0.05). The postoperative actual prepatellar cortical thickness of the study group was significantly smaller than that of the control group ( P<0.05). D1 and D3 in the study group were significantly higher than those in control group ( P<0.05), but there was no significant difference in D2 between the two groups ( P>0.05). CONCLUSION The locator can improve the accuracy of MPFL reconstruction surgery, reduce the possibility of intraoperative damage to the articular surface of patella and postoperative patellar fractures.

Objective To observe the effects of Hedan tablet on cytokines and oxidation factors in APOE-/-mouse, and to explore its effect on atherosclerosis and to explore its behind mechanism. Methods APOE-/-mice (n=50) were randomly divided into control group, model group, low dose Hedan tablet treatment group, high dose Hedan tablet treatment group and simvastatin treatment group. Mice in control group were given normal feed while mice in other groups were fed with high cho?lesterol diet. Hedan or Simvastatin was administrated intra-gastrically while normal saline was given to model group in the same route. After 12 weeks, mice were sacrificed to observe the mRNA level of tumor necrosis factor-α(TNF-αmRNA) in aorta by RT-PCR. Mean while, serum levels of interleukin-1 (IL-1), interleukin-10 (IL-10), malonaldehyde (MDA) and su?peroxide dismutase (SOD) were determined in different groups. Results Compared with control group, TNF-αmRNA tran?scription level as well as serum levels of IL-1 and MDA significantly increase while serum levels of IL-10 and SOD de?creased remarkably in model group, (P<0.01). Compared with model group, mRNA levels of TNF-αas well as serum levels of IL-1 and MDA were significantly decreased while serum levels of IL-10, SOD were greatly increased in low dose and high dose Hedan tablet treatment groups as well as in simvastatin treatment group (P<0.01). Conclusion Hedan tablet inhibit the formation of atherosclerosis through its anti-oxidation role and anti-inflammation role.
