BackgroundInvasive vagus nerve stimulation therapy has been approved for the adjunctive treatment of treatment-resistant depression， which may contribute to the anti-inflammatory properties of vagus nerve stimulation （VNS）， whereas the efficacy of non-invasive transcutaneous cervical vagus nerve stimulation （tcVNS） in treating major depressive disorder （MDD） and its impact on plasma inflammatory factors remain unclear. ObjectiveTo observe the effect of escitaloprom combined with tcVNS on the status of depression， anxiety and sleep quality as well as the plasma levels of interleukin-6 （IL-6） and interleukin-10 （IL-10） in MDD patients， in order to provide references for the recovery and treatment of MDD patients. MethodsFrom August 21， 2019 to April 17， 2024， 45 patients who met the diagnostic criteria for MDD in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） were recruited from the psychosomatic outpatient clinic of the First Affiliated Hospital of Air Force Military Medical University. Subjects were divided into study group （n=23） and control group （n=22） using random number table method. All patients were treated with escitalopram. On this basis， study group added a 30-minute tcVNS therapy once a day for 4 weeks. While control group was given corresponding sham stimulation， and the duration of each stimulation lasted 30 seconds. Before and after 4 weeks of treatment， Hamilton Depression Scale-17 item （HAMD-17） was used to assess depressive symptoms， and HAMD-17 anxiety/somatization subfactor and insomnia subfactor were used to assess patients' anxiety/somatization symptoms and sleep quality. Levels of plasma IL-6 and IL-10 were measured by enzyme-linked immunosorbent assay （ELISA）. ResultsThe generalized estimating equation model yielded a significant time effect for HAMD-17 total score， anxiety/somatization subfactor score and insomnia subfactor score in both groups （Wald χ²=315.226， 495.481， 82.420， P<0.01）. After 4 weeks of treatment， HAMD-17 total score and anxiety/somatization subfactor score of study group were lower than those of control group， with statistically significant differences （Wald χ²=4.967， 32.543， P<0.05 or 0.01）， while no statistically significant difference was found in the insomnia subfactor score between two groups （Wald χ²=0.819， P=0.366）. Significant time effects were reported on plasma IL-6 and IL-10 levels in both groups （Wald χ²=21.792， 5.242， P<0.05 or 0.01）. Compared with baseline data， a reduction in plasma IL-6 levels was detected in both groups （Wald χ²=22.015， 6.803， P<0.01）， and an increase in plasma IL-10 levels was reported in study group （Wald χ²=5.118， P=0.024） after 4 weeks of treatment. ConclusionEscitalopram combined with tcVNS therapy is effective in improving depressive symptoms， anxiety/somatization symptoms and sleep quality in patients with MDD. Additionally， it helps reduce plasma IL-6 levels and increase IL-10 levels. ［Funded by Shaanxi Provincial Key Research and Development Program-General Project （number， 2023-YBSF-185）， www.clinicaltrials.gov number， NCT04037111］

Background: Diabetic pain patients have increased pain at night. Exosomes can relieve neuropathic pain. This study aimed to investigate the efficacy of exosome administration at different time points in relieving diabetic neuropathic pain (DNP) in rats. Methods: M2 macrophages from bone marrow were induced in mice and exosomes were extracted. A diabetic rat model was induced using streptozotocin, with the mechanical withdrawal threshold (MWT) of the rats beingmeasured at ≤ 80% of the basal value after 14 days, indicating successful construction of the DNP rat model.Exosomes were administered on three consecutive days at ZT0 (zeitgeber time) and ZT12. Parameters including blood glucose levels, body weight, MWT, and thermal withdrawal latency (TWL) were assessed in the rats. The lumbar spinal cord of rats was examined on days 21 and 28 to measure inflammatory factors and observe the expression of M1 and M2 microglia. Furthermore, microglia were exposed to lipopolysaccharide (LPS) and LPS + exosomes in a controlled in vitro setting to assess alterations in microglia phenotype involving the NF-kB p65 andIKBα inflammatory signaling pathways. Results: The findings revealed that administration of exosomes during the rat resting period at ZT12 resulted in increased MWT and TWL, as well as a shift in microglia polarization towards the M2 phenotype. In vitro analysis indicated that exosomes influenced microglia polarization and suppressed the phosphorylation of NF-kB p65 andIKBα.  Conclusions Temporal therapy with exosomes effectively reduces pain in DNP rats by polarizing microglia andaffecting NF-kB p65 and IKBα signaling pathways.

Systemic lupus erythematosus （SLE）， a refractory autoimmune disease， is among the dominant diseases where traditional Chinese medicine （TCM） shows advantages in the field of rheumatology and immunology. The China-Japan Friendship Hospital hosted the "46^th Youth Salon on Dominant Diseases （Systemic Lupus Erythematosus）" organized by the China Association of Chinese Medicine， which led to a consensus on "the advantages， challenges， interdisciplinary approaches， and translational achievements of integrated TCM and Western medical approaches in the diagnosis and treatment of SLE." The diagnosis and treatment of SLE currently face several challenges， such as frequent misdiagnosis and missed diagnosis in the early stages， difficulty in achieving treatment targets， multiple side effects from pharmacotherapy， and the lack of management strategies for special populations， all of which hinder the fulfillment of the clinical needs of patients. Integrated TCM and Western medical approaches can improve clinical symptoms such as skin erythema， aversion to cold and cold limbs， fatigue， dry mouth， restlessness， and heat sensation in the palms and soles， thereby improving patients' quality of life. The approaches also help consolidate the efficacy of conventional Western medicine， slow disease progression， reduce relapse rates， address multi-organ involvement， and prevent or treat complications. Additionally， they enhance efficacy and reduce toxicity， prevent the side effects of Western medications， help reduce hormone use， and offer distinct advantages in the individualized intervention of special populations， contributing to the whole-process management of the disease. However， evidence-based medical support for this integrated approach remains limited， and the quality of available evidence is generally low. Common evaluation systems and modern research methodologies should be adopted to clarify the efficacy of TCM in SLE treatment. Efforts should be made to carry out high-quality evidence-based medical research， strengthen the development of fundamental and pharmacological research， and further explain the distinct advantages of TCM in the diagnosis and treatment of SLE. Future efforts should focus on advancing the integration of TCM and modern medicine， incorporating multi-omics technologies， individualized stratification， and other precision medicine concepts， in combination with artificial intelligence. Moreover， interdisciplinary collaboration should be promoted to utilize modern technology in exploring the essence of TCM theories and screening effective formulae， thereby comprehensively improving the diagnosis and treatment of SLE through integrated TCM and Western medical approaches.

It is proposed that cold qi-induced accumulation encapsulates the core pathogenesis of the inflammation-cancer transformation in inflammatory bowel disease （IBD）. Cold pathogens may serve as the initiating factor. When first invading the intestines， cold pathogens obstruct the flow of qi； over time， the lingering cold impairs the middle jiao （焦）， eventually leading to the accumulation of cold-phlegm and blood stasis. Based on the progressive nature of this transformation， the process can be divided into three stages， active stage， remission stage， and carcinogenic stage. In the active stage， the main pathogenesis involves stagnation of cold qi and accumulation of damp-heat in the intestines； in the remission stage， cold qi impairs the spleen， disrupting its transport and transformation functions； and in the carcinogenic stage， the mechanisms include cold-induced accumulation， phlegm accumulation from cold， and stagnation of cold and blood stasis. Accordingly， the treatment strategies are proposed.In the active stage， regulating qi， relieving stagnation， and harmonizing cold and heat； in the remission stage， warming yang， dispersing cold， tonifying qi， and strengthening the spleen； and in the carcinogenic stage， promoting qi circulation， dispersing cold， resolving phlegm， activating yang， and eliminating stasis to remove accumulation. These approaches aim to interrupt the transformation of IBD into colorectal cancer.
