Background: Depression is among the most common neuropsychiatric complications after stroke, having a negative impact on one's quality of life. A number of therapeutic modalities have been used for post-stroke depression (PSD) including traditional Chinese medicine (TCM). However, a lack of objectivity in TCM hampers further improvement in diagnosis and research, since TCM diagnosis is mainly based on subjective judgment of clinicians. In this study, a modern TCM diagnostic device was used to conduct an objective study of pulse and tongue features in PSD patients and healthy individuals. Methods: A total of 67 volunteers participated. Pulse and tongue information of each participant was acquired and analyzed by the TCM Four Diagnosis Auxiliary Apparatus. Quantitative data were gathered and compared between the PSD group and the healthy group. Results: Higher rates of weak, slow, slippery, and string pulse were observed in the PSD group (p < 0.01), whereas normal pulse (p < 0.01) was detected in the healthy group. In the tongue analysis, higher rates of purple tongue (p < 0.01) with yellow fur (p < 0.01) and pale-pink tongue (p = 0.023) with white fur (p < 0.01) were observed in the PSD and the healthy groups, respectively. Abnormal tongue features (old, soft, thin, enlarged, thorny, and cracked) were detected (p < 0.05) in the PSD group. Conclusions: Objective and quantitative data of PSD patients and healthy individuals may help providing valuable clinical information for PSD research and establish quantitative TCM diagnostic standards for pulse and tongue diagnosis in clinical practice and research.
Objective: The curative effect of pneumatic pulsatile cupping on pain has been shown. This study was conducted to investigate effects of the pulsating frequency of pneumatic pulsatile cupping, compared with traditional cupping (TC), on body pain and quality of life (QoL) in people with suboptimal health status (SHS). Materials and Methods: Ninety-six participants with SHS were randomized to low-frequency (LF; n = 24) or high-frequency (HF; n = 24) pulsating cupping, traditional cupping (TC; n = 24), or wait-list (WL; n = 24) groups. The LF, HF, and TC groups received 4 sessions of cupping over 2 weeks. Visual analogue scale (VAS; 0-100 mm) pain level and Short-Form-36 (SF-36) QoL measurements were taken before and after the intervention.
The quality and yields of Sorghum bicolor plants are seriously affected by saline-alkali conditions. NAC (NAM, ATAF, and CUC) transcription factors are plant specific and have various functions in plant development and response to various stresses. To investigate how GsNAC2 functions in sorghum responses to saline-alkali treatment, the characteristics of GsNAC2 were analysed by bioinformatics methods, and NaHCO3:Na2CO3 (5:1, 75 mM, pH 9.63) saline-alkali stress solution was applied when sorghum plants were 2 weeks old. The research results show that GsNAC2 belongs to the NAC gene family. GsNAC2 was significantly induced by saline-alkali treatment and strongly expressed in sorghum leaves. GsNAC2-overexpressing sorghum plants had increased plant height, dry weight, moisture content, root activity, leaf length, chlorophyll content, stomatal conductance, relative root activity, relative chlorophyll content, relative stomatal conductance, and relative transpiration rate after saline-alkali treatment. Lower H2O2 and O2− levels, relative permeability of the plasma membrane, and malondialdehyde (MDA) content were found in GsNAC2-overexpressing sorghum. In transcriptome analysis, clusters of orthologous groups (COG) analysis showed that a high proportion of differentially-expressed genes (DEGs) participated in defence mechanisms at each processing time, and 18 DEGs related to synthetic glutathione were obtained. Gene expression analysis revealed that key genes in glutathione biosynthesis pathways were upregulated. GR and GSH-Px activities were increased, and GSH accumulated more with the overexpression of GsNAC2 after saline-alkali treatment. Furthermore, these results suggest that GsNAC2 acts as a potentially important regulator in response to saline-alkali stress and may be used in molecular breeding to improve crop yields under adverse environmental conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
