OBJECTIVE: To enhance the understanding of identifying personalized pharmacotherapy options in Traditional Chinese Medicine(TCM), and further support the registration of new TCM drugs. METHODS: Generalized Boosted Models and XGBoost were employed to construct a classification model to identify the bad prognosis factors in resistant hypertension(RH) patients. Furthermore, we used association analysis to explore the rules of "symptomsyndrome" and "symptom-herb" for the major influencing factors, in order to summarize prescription pattern and applicable patients of TCM. RESULTS: Patients with major adverse cardiac events mostly have complex symptoms of phlegm, stasis, deficiency and fire intermingled with each other, and finally summarized the human experience of using Chinese herbal medicine to precisely intervene in some symptoms of RH patients on the basis of conventional Western medical treatment. CONCLUSIONS: Machine learning algorithms can make full use of human use experience and evidence to save clinical trial resources and accelerate the development of TCM varieties.

research on acupuncture robots based on the OptiTrack motion capture system and a robotic arm

引用

Journal of Traditional Chinese Medicine 2025年第1期45卷 201-212页

作者： HE Ling YANG Hui LI Kang WANG Junwen SUN Zhibo YANG Jinsheng ZHANG Jing College of Biomedical Engineering Sichuan University West China Biomedical Big Data Center Sichuan University institute of basic Theory for Chinese Medicine institute of basic Theory for Chinese Medicine China Academy of Chinese Medical Sciences

OBJECTIVE: To propose an automatic acupuncture robot system for performing acupuncture operations. METHODS: The acupuncture robot system consists of three components: automatic acupoint localization, acupuncture manipulations, and De Qi sensation detection. The OptiTrack motion capture system is used to locate acupoints, which are then translated into coordinates in the robot control system. A flexible collaborative robot with an intelligent gripper is then used to perform acupuncture manipulations with high precision. In addition, a De Qi sensation detection system is proposed to evaluate the effect of acupuncture. To verify the stability of the designed acupuncture robot, acupoints' coordinates localized by the acupuncture robot are compared with the Gold Standard labeled by a professional acupuncturist using significant level tests. RESULTS: Through repeated experiments for eight acupoints, the acupuncture robot achieved a positioning error within 3.3 mm, which is within the allowable range of needle extraction and acupoint insertion. During needle insertion, the robot arm followed the prescribed trajectory with a mean deviation distance of 0.02 mm and a deviation angle of less than 0.15°. The results of the lifting thrusting operation in the Xingzhen process show that the mean acupuncture depth error of the designed acupuncture robot is approximately 2 mm, which is within the recommended depth range for the Xingzhen operation. In addition, the average detection accuracy of the De Qi keywords is 94.52%, which meets the requirements of acupuncture effect testing for different dialects. CONCLUSION: The proposed acupuncture robot system streamlines the acupuncture process, increases efficiency, and reduces practitioner fatigue, while also allowing for the quantification of acupuncture manipulations and evaluation of therapeutic effects. The development of an acupuncture robot system has the potential to revolutionize low back pain treatment and improve patient outco

Stem-leaf saponins of Panax notoginseng attenuate experimental Parkinson's disease progression in mice by inhibiting microglia-mediated neuroinflammation via P2Y2R/PI3K/AKT/NFκB signaling pathway

引用

Chinese Journal of Natural Medicines 2025年第1期23卷 43-53页

作者： Hui Wu Chenyang Ni Yu Zhang Yingying Song Longchan Liu Fei Huang Hailian Shi Zhengtao Wang Xiaojun Wu Shanghai Key Laboratory of Compound Chinese Medicines The Ministry of Education (MOE) Key Laboratory for Standardization of Chinese Medicines Institute of Chinese Materia Medica The MOE Innovation Centre for Basic Medicine Research on Qi-Blood TCM Theories Shanghai University of Traditional Chinese Medicine

Stem-leaf saponins from Panax notoginseng(SLSP) comprise numerous PPD-type saponins with diverse pharmacological properties; however, their role in Parkinson's disease(PD),characterized by microglia-mediated neuroinflammation, remains unclear. This study evaluated the effects of SLSP on suppressing microglia-driven neuroinflammation in experimental PD models, including the 1-methyl-4-phenylpyridinium(MPTP)-induced mouse model and lipopolysaccharide(LPS)-stimulated BV-2 microglia. Our findings revealed that SLSP mitigated behavioral impairments and excessive microglial activation in models of PD, including MPTP-treated mice. Additionally, SLSP inhibited the upregulation of inducible nitric oxide synthase(i NOS) and cyclooxygenase-2(COX2) and attenuated the phosphorylation of PI3K,protein kinase B(AKT), nuclear factor-κB(NFκB), and inhibitor of NFκB protein α(IκBα) both in vivo and in vitro. Moreover, SLSP suppressed the production of inflammatory markers such as interleukin(IL)-1β, IL-6, and tumor necrosis factor alpha(TNF-α) in LPS-stimulated BV-2cells. Notably, the P2Y2R agonist partially reversed the inhibitory effects of SLSP in LPStreated BV-2 cells. These results suggest that SLSP inhibit microglia-mediated neuroinflammation in experimental PD models, likely through the P2Y2R/PI3K/AKT/NFκB signaling pathway. These novel findings indicate that SLSP may offer therapeutic potential for PD by attenuating microglia-mediated neuroinflammation.

Tackling the microlensing wave effects of strong lensing gravitational waves with TAAH

Science China(Physics,Mechanics & Astronomy) 2025年第1期68卷 253-254页

作者： Zuhui Fan South-Western institute for Astronomy research Yunnan UniversityKunming 650500China

The rapid development of gravitational wave(GW) observations since their first detection in 2015 [1] has opened a completely new window for exploring the Universe. Consequently, astronomical research has entered the multimessenger era, allowing us to use different tracers to view the cosmos from various perspectives. Among others, the appealing application of gravitational wave events from compact binary mergers is that they can act as standard sirens to determine absolute cosmic distances entirely independent of standard candles. This approach is one of the most promising means to solve the current H0tension problem.
