Unsmooth pulse is one of the most important pulses in TCM diagnostics. We constructed the wave intensity (WI) images of unsmooth pulse based on the pressure wave (P), flow velocity wave (U), and WI [(dP/dt)(dU/dt)] by ALOKA Prosound α 10 Color Doppler. The characteristic of Cunkou normal pulse could be summarized as follows: compared to Renying pulse, its W1 amplitude is smaller and NA wave is more obvious, while the W2 wave is indistinct or even invisible, and the R-1st is longer than that of Renying pulse. The principal U wave of Renying pulse looks like “Λ” shape, while it looks like an arched blunt “∩” shape in Cunkou pulse, and the amplitude of U wave in Cunkou pulse is smaller. The direction of the principal U wave in Cunkou unsmooth pulse is up, which shows hoof boots “h” shape with high amplitude and a significant notch on declined branch; the amplitude of predicrotic wave in unsmooth pulse P wave is significantly higher, which could be even higher than that of h1, resulting in early appearance of h3 or integrating with h1, which forms a wide and blunt peak. Unsmooth pulse shows poorer vascular elasticity and greater vascular stiffness.

Abstract Background: Measuring carotid and radial pulses as a diagnostic method plays a vital role in sphygmology applied via traditional Chinese medicine (TCM). In particular, many TCM theories and doctors have indicated that the pulse force ratio is closely correlated with human physiological conditions, such as weight and body temperature. However, few studies have explored these potential correlations. Thus, the purpose of this study was to investigate the relationships between the pulse strength ratio and human metabolism indicators.Methods: The carotid and radial relative artery blood flow velocity (RABFV) and pulse force from 122 normal adults were examined by ultrasound and manual palpation by a doctor, and the same group was tested via a thermal texture map (TTM).Results: Obvious differences in the body side and sex were not observed in the ratio of carotid and radial RABFV among normal individuals (p>0.05). However, the ratio of young people was greater than that of old people (p<0.001), and strong support was obtained for traditional Chinese medicine (TCM) assumptions of seasonal differences in the ratio (p<0.001). Furthermore, we discovered that the ratio had a negative correlation with BMI and torso temperature but a positive correlation with hand temperature.Conclusion: Our results demonstrated that the ratio of carotid and radial RABFV could serve as an indicator of human physical conditions, such as BMI and human temperature, and represents a valuable tool for evaluating yin-yang properties in TCM clinical practice. The close correlations reported above verified some theories of TCM and provided strong support for sphygmology in TCM.

Vein Occlusion

Branch retinal vein occlusion (BRVO) is a common retinal vascular disorder leading to visual impairment. Currently, the general strategies for BRVO are symptomatic therapies. Cardiovascular aspects are essential risk factors for BRVO. The traditional Chinese medicine hexuemingmu (HXMM), consisting of tanshinol and baicalin, dilates the vasculature and accelerates microcirculation. Therefore, the aim of this study was to determine the efficacy and possible mechanism of HXMM in a BRVO rat model established by laser photocoagulation. Successful BRVO rat models were treated with different doses of HXMM. Fundus photography and fluorescein fundus angiography (FFA) of the animals were applied. The retinal layers were measured by optical coherence tomography (OCT). Full-field electroretinography (ffERG) was applied to evaluate the retinal function. The ear vein flow velocity was measured via a microcirculation detector. The expression of the vascular endothelial growth factor (VEGF-α) was measured via western blotting and immunofluorescent staining. Our study found that retinal edema predominantly occurred in the inner nuclear layer (INL) and outer nuclear layer (ONL). The retinal edema of the treated groups was significantly relieved in the early stage of BRVO as visualized via OCT detection and HE staining. The amplitudes of the b wave and oscillatory potentials (OPs) waves of ffERG in the treated groups were increased compared with those of the control group at several detection points (3, 5, 7, 10, 14, and 21 d postocclusion). The expression of VEGF-α was reduced in the treated groups at an early stage of BRVO. Furthermore, the ear vein flow velocity of the HXMM treatment groups was faster than that of the control group. Thus, our study indicates that the traditional Chinese medicine HXMM could ameliorate retinal edema and rescue the retinal structure and function in BRVO models through promoting occluded vein recanalization, improving microcirculation, and regulating the expression of VEGF-α.
