By reviewing the physical biological research on the activation of acupoint effects by acupuncture， this paper explains the activation mechanism from the perspective of the generation and transmission of mechanical signals caused by acupuncture， and reveals the physical-chemical coupling processes in the acupoint microenvironment. Future research should focus on locally mechanosensitive cells， further exploring how acupuncture mechanical signals trigger dynamic changes in cells and molecules in the acupoints， and the physical-chemical information transduction mechanism， which will provide scientific evidence for the acupoint activation during acupuncture. Related studies will contribute to a deeper understanding of the scientific principles behind acupuncture and promote its clinical application and development.

OBJECTIVE To prepare the β -cyclodextrin （ β -CD） inclusion complex with volatile oil from Qianghuo qushi qingwen granules， and to characterize and quantitatively analyze the inclusion complex. METHODS The comprehensive scores calculated by inclusion rate and inclusion compound yield were used as indicators for screening the inclusion method. The single-factor experiments and Box-Behnken response surface experiments were used to op timize the inclusion conditions， with the above comprehensive score as response value， and taking the ratio of β -CD to volatile oil， inclusion temperature and inclusion time as indexes. The volatile oil inclusion complex of Qianghuo qushi qingwen granules was prepared according to the determined optimal process， followed by validation. Ultraviolet （UV）-visible spectroscopy， thin-layer chromatography （TLC）， and microscopic imaging were also performed. Ultra-high performance liquid chromatography was used to determine the contents of perillaldehyde， pogostone and atractylodin. RESULTS The saturation aqueous solution method was adopted. The optimal inclusion process conditions were as follows： the ratio of β -CD to volatile oil was 7.5∶1， the inclusion temperature was 40 ℃， and the inclusion time was 2.2 h. In three verification experiments， the average inclusion rate was 72.32%， the average yield of inclusion compound was 74.45%， the average comprehensive score was 72.96 points， and the relative error with the predicted value （74.15 points） of the model was 1.61%. UV-visible spectroscopy， TLC and microscopic imaging showed that β -CD and volatile oil successfully formed a new inclusion complex. The average contents of perillaldehyde， pogostone and atractylodin were 4.498 2， 0.814 9， 0.905 7 mg/g， respectively， with RSDs of 0.31%， 0.56% and 0.63% （ n ＝3）. CONCLUSIONS A stable and feasible preparation process of the volatile oil inclusion complex of Qianghuo qushi qingwen granules is successfully established.

With the integration of 5G communication technology and robotic surgical systems, remote robot-assisted thoracic surgery is overcoming geographical barriers, offering an innovative approach to addressing the uneven distribution of medical resources. This study conducted a systematic literature review—using databases such as PubMed and CNKI, with the search period extending up to 2025—incorporating clinical studies, case reports, and review articles to comprehensively evaluate the clinical efficacy and safety of 5G-enabled remote robot-assisted thoracic surgery (5G-RRATS). The analysis also examined current technological limitations and potential future development trajectories. Existing evidence indicates that, given adequate technical support, 5G-RRATS can achieve perioperative outcomes comparable to those of conventional local robotic surgeries across procedures including pulmonary wedge resection, lobectomy, and esophagectomy. Furthermore, it demonstrates potential advantages in minimizing surgical incisions and reducing intraoperative blood loss. Nevertheless, challenges related to network stability, latency control, interdisciplinary collaboration between medical and engineering teams, and legal, regulatory, and ethical considerations continue to hinder widespread clinical adoption. Looking ahead, the emergence of a "one-to-many" remote surgical model, combined with the integration of artificial intelligence and augmented reality technologies, as well as advancements in low-orbit satellite communications, may enable 5G-RRATS to further advance precision and efficiency in thoracic surgery, thereby facilitating equitable access to high-quality care for a broader patient population.

AIM: To investigate the expression of Ficolin-3 and secreted frizzled-related protein 5(SFRP5)in the serum of patients with type 2 diabetes mellitus(T2DM)combined with diabetic retinopathy(DR)and their diagnostic value.METHODS: Prospectively selected patients with T2DM combined with DR admitted to the hospital from May 2023 to May 2025 were divided into non-proliferative and proliferative groups according to the severity of DR. Another patients with T2DM alone during the same period were selected as the T2DM group. ELISA was used to detect Ficolin-3 and SFRP5 levels; Correlation of serum Ficolin-3, SFRP5 levels, and inflammatory markers in T2DM patients with DR were analyzed using Pearson method; Logistic regression was used to analyze related influencing factors; ROC curve analysis was used to evaluate the diagnostic value of serum Ficolin-3 and SFRP5 for DR in T2DM patients.RESULTS: This study included a total of 108 patients with T2DM combined with DR(57 cases in the non-proliferative group, 51 cases in the proliferative group)and 108 cases in the T2DM group. The non-proliferative group had an average age of 59.01±6.28 y, with 34 males and 23 females. The proliferative group had an average age of 59.09±6.35 y, with 30 males and 21 females. The T2DM group had an average age of 58.96±6.18 y, with 62 males and 46 females.The serum levels of Ficolin-3, TNF-α, and IL-6 in the non-proliferative and proliferative groups were higher than those in the T2DM group(all P<0.05), while the level of SFRP5 was lower than that in the T2DM group(all P<0.05). The serum levels of Ficolin-3, TNF-α, and IL-6 in the proliferative group were higher than those in the non-proliferative group(all P<0.05), and the level of SFRP5 was lower than that in the non-proliferative group(P<0.05).Complying with Pearson correlation analysis showed that serum Ficolin-3 was negatively correlated with SFRP5(P<0.05), and both were related to TNF-α and IL-6(all P<0.001). Logistic analysis showed that the course of diabetes, SUA, HbA1c, Ficolin-3, TNF-α, and IL-6 were the risk factors for T2DM patients with DR(all P<0.05), and SFRP5 was a protective factor(P<0.05). Complying with the ROC curve, the AUC values of serum Ficolin-3 and SFRP5 alone and their combination for diagnosing T2DM patients with DR were 0.774, 0.793, and 0.864, respectively. The AUC of combined diagnosis was better than that of single diagnosis(Z=2.694, Z=2.708, both P<0.05).CONCLUSION: In patients with T2DM complicated by DR, serum levels of Ficolin-3 and SFRP5 are abnormally expressed. Both are influencing factors for T2DM with DR, and the combined detection can improve the diagnostic value in these patients.
