| 1 | Effect of pulsatile perfusion during cardiopulmonary bypass in terms of radial artery sphygmogram显示文摘OBJECTIVE: To investigate a quantitative method for using radial artery pulse waveforms to assess the effect of pulsatile flow during cardiopulmonary bypass(CPB).METHODS: A total of 34 adults with heart disease who underwent open-heart surgery between April2010 and January 2011 were randomized into a pulsatile perfusion group(n=17) and a non-pulsatile perfusion group(n=17). Radial arterial pulse waveforms of pulsatile and non-pulsatile perfusion patients were observed and compared before and during CPB.RESULTS: No pulse waveform could be detected at patients' radial artery in both groups when the aorta was cross-clamped. Pulse waveforms could be detected at pulsatile perfusion patients' radial artery, but could not be detected at non-pulsatile perfusion patients' radial artery during CPB. Additionally, patients' pulse waveforms during pulsatile perfusion were lower than those before the operation.CONCLUSION: Our findings indicate that radial artery sphygmogram can be used as a valid indicator to evaluate the effectiveness of pulsatile perfusion during CPB. | Zhifeng Zhang Jiatuo Xu Enyuan Zhu Qi Zhang Lu Yu Yongbing Qiu Jianguo Tang Zhaofu Fei Xin Li Liping Tu Chouping Han Ying Liu Zhen Guo Changle Zhou Meiyu Shi Yingxin Qian Yimin Bao Xinming Ji | 2014 | Journal of Traditional Chinese Medicine2014，34，6： | 2 |
| 2 | Digital tongue image analyses for health assessment显示文摘Traditional Chinese Medicine(TCM),as an effective alternativemedicine,utilizes tongue diagnosis as a major method to assess the patient’shealthstatusbyexaminingthe tongue’s color,shape,and texture.Tongue images can also give the pre-disease indications without any significant disease symptoms,which provides a basis for preventive medicine and lifestyle adjustment.However,traditional tongue diagnosis has limitations,as the process may be subjective and inconsistent.Hence,computer-aided tongue diagnoses have a great potential to provide more consistent and objective health assessments.This paper reviewed the current trends in TCMtongue diagnosis,including tongue image acquisition hardware,tongue segmentation,feature extraction,color correction,tongue classification,and tongue diagnosis system.We also present a case of TCM constitution classification based on tongue images. | Jiacheng Xie Congcong Jing Ziyang Zhang Jiatuo Xu Ye Duan Dong Xu | 2021 | Medical Review2021，1，2： | 1 |
| 3 | Dark red tongue color formation caused by hyperglycemia is attributed to decreased blood flow of tongue tissue partially due to nuclear factor-kappa B pathway activation显示文摘OBJECTIVE:To investigate the potential mechanisms underlying the dark red tongue color formation induced by hyperglycemia.METHODS:A high-fat diet and intraperitoneal injection of streptozotocin were used to establish a diabetes model.The color and blood flow of tongues were analyzed by the Tongue Diagnosis Analysis System and laser Doppler flowmetry,respectively.Inflammatory factors and adhesion factors were measured in the circulation and tongue tissue by an enzyme-linked immunosorbent assay.Western blotting was employed to evaluate nuclear factor-kappa B(NF-κB)p50 and inhibitor of kappa B kinase protein expression levels in the tongue.Then,the NF-κB inhibitor,pyrrolidine dithiocarbamic acid ammonium salt was utilized to repress NF-κB pathway activation to validate that the NF-κB pathway plays a key role in blood flow and dark red tongue color formation.RESULTS:The diabetic rats displayed a dark red tongue color that was accompanied by NF-κB pathway activation and decreased blood flow in the tongue.These effects could be reversed by the NF-κB inhibitor.CONCLUSIONS:Our investigation demonstrated that hyperglycemia led to dark red tongue color formation by decreasing blood flow in the tongue,which was partly due to NF-κB pathway activation. | JIN Shenyi LIU Yahua HAN Xu CAI Mengjie XU Jiatuo LU Hao CHEN Qingguang | 2023 | Journal of Traditional Chinese Medicine2023，43，6： | 0 |
