This study was aimed to investigate the effect of visceral pain and water metabolism on irritable bowel syndrome with diarrhea (IBS-D) model rats by moxibustion and its products. A total of 40 SD rats were randomly di-vided into the normal group, model group, moxibustion group, non-smoke moxibustion group, and moxa smoke group. IBS-D model was induced by colorectal distension with an inflatable balloon. The general condition of rats was ob-served. Visceral pain was assessed by abdominal withdrawal reflex (AWR) scores. The immunohistochemical method was used in the detection of claudin-1, AQP3, AQP8 and Na+/K+-ATPase protein expression. The results showed that compared with the normal group, the AWR scores, claudin-1, AQP3, AQP8 and Na+/K+-ATPase protein expres-sion in the colon were decreased in the model group (P < 0.01). The stool was loose, which was on hair around the anus. After moxibustion, non-smoke moxibustion and moxa smoke stimulation, the stool conditions of IBS-D model rats were improved. The AWR scores were decreased in different degrees (P < 0.05 or P < 0.01). Except Na+/K+-ATPase, expressions of claudin-1, AQP3 and AQP8 in colon were increased in different degrees (P < 0.05 or P <0.01). The comprehensive therapeutic effect showed that moxibustion was better than non-smoke moxibustion; and non-smoke moxibustion was better than moxa smoke stimulation. It was concluded that the combination of warm stimulation, optical radiation and moxa smoke induced best effect in improving visceral pain and water metabolism on IBS-D model rats. Among them, warm stimulation and optical radiation may play the main role.

OBJECTIVE: To establish a supplementary diagnostic indicator (infrared radiant intensity) in tongue diagnosis of traditional Chinese medicine (TCM) in patients with hyperplasia of mammary glands through correlation analysis of infrared radiant intensity between hyperplastic breast tissue and tongue surface. METHODS: Infrared radiant intensity of the hyperplastic breast tissue and different points on tongue surface in 20 cases of hyperplasia of mammary glands with liver-energy stagnation and phlegm retention syndrome and 16 cases of hyperplasia of mammary glands with irregular thoroughfare and conception vessels syndrome were measured with external infrared spectrometer PHE-201 made by Shanghai Institute of Technical Physics. Correlation of infrared radiant intensity between the hyperplastic breast tissue and the different points on tongue surface was assessed by using bivariate correlation analysis. RESULTS: The results showed that the numbers of positive correlated wave bands of infrared radiant intensity between the hyperplastic breast tissue and different detected points on tongue surface in the patients with liver-energy stagnation and phlegm retention syndrome and irregular thoroughfare and conception vessels syndrome were 127 (83.55%) and 71 (46.71%), respectively. Infrared radiant intensity between the hyperplastic breast tissue and the tongue surface had a positive correlation. CONCLUSION: Infrared radiant intensity can be used as one of supplementary diagnostic indicators in TCM tongue diagnosis of hyperplasia of mammary glands.

BACKGROUND:
Cutaneous wound healing represents a common fundamental phenomenon requiring the participation of cells of distinct types and a major concern for the public. Evidence has confirmed that photobiomodulation (PBM) using near-infrared (NIR) can promote wound healing, but the cells involved and the precise molecular mechanisms remain elusive.
METHODS:
Full-thickness skin defects with a diameter of 1.0 cm were made on the back of rats and randomly divided into the control group, 10 J, 15 J, and 30 J groups. The wound healing rate at days 4, 8, and 12 postoperatively was measured. HE and Masson staining was conducted to reveal the histological characteristics. Immunofluorescence staining was performed to label the epidermal stem cells (ESCs) and hair follicle stem cells (HFSCs). Western blot was performed to detect the expressions of proteins associated with ESCs and HFSCs. Cutaneous wound tissues were collected for RNA sequencing. Gene ontology and the Kyoto Encyclopedia of Genes and Genomes analysis was performed, and the hub genes were identified using CytoHubba and validated by qRT-PCR.
RESULTS:
PBM can promote reepithelialization, extracellular matrix deposition, and wound healing, increase the number of KRT14+/PCNA+ ESCs and KRT15+/PCNA+ HFSCs, and upregulate the protein expression of P63, Krt14, and PCNA. Three hundred and sixty-six differentially expressed genes (DEGs) and 7 hub genes including Sox9, Krt5, Epcam, Cdh1, Cdh3, Dsp, and Pkp3 were identified. These DEGs are enriched in skin development, cell junction, and cadherin binding involved in cell–cell adhesion etc., while these hub genes are related to skin derived stem cells and cell adhesion.
CONCLUSION
PBM accelerates wound healing by enhancing reepithelialization through promoting ESCs and HFSCs proliferation and elevating the expression of genes associated with stem cells and cell adhesion. This may provide a valuable alternative strategy to promote wound healing and reepithelialization by modulating the proliferation of skin derived stem cells and regulating genes related to cell adhesion.

BACKGROUND:
Although newly formed constructs of feasible pressure-preadjusted bone marrow mesenchymal stem cells (BMSCs) and platelet-rich fibrin (PRF) showed biomechanical flexibility and superior capacity for cartilage regeneration, it is still not very clear how BMSCs and seed cells feel mechanical stimuli and convert them into biological signals, and the difference in signal transduction underlying mechanical and chemical cues is also unclear.
METHODS:
To determine whether mechanical stimulation (hydrostatic pressure) and chemical cues (platelet-rich fibrin, PRF) activate canonical or noncanonical Wnt signaling in BMSCs, BMSCs cocultured with PRF were subjected to hydrostatic pressure loading, and the activation of the Wnt signaling molecules and expression of cartilage-associated proteins and genes were determined by western blotting and polymerase chain reaction (PCR). Inhibitors of canonical or noncanonical Wnt signaling, XVX-939 or L690,330, were adopted to investigate the role of Wnt signaling molecules in mechanically promoted chondrogenic differentiation of BMSCs.
RESULTS:
Hydrostatic pressure of 120 kPa activated both Wnt/b-catenin signaling and Wnt/Ca2+ signaling, with the the maximum promotion effect at 60 min. PRF exerted no synergistic effect on Wnt/b-catenin signaling activation. However, the growth factors released by PRF might reverse the promotion effects of pressure on Wnt/Ca2+ signaling. Real-time PCR and Western blotting results showed that pressure could activate the expression of Col-II, Sox9, and aggrecan in BMSCs cocultured with PRF. Blocking experiment found a positive role of Wnt/b-catenin signaling, and a negative role of Wnt/ Ca2+ signaling in chondrogenic differentiation of the BMSCs. Mutual inhibition exists between canonical and noncanonical Wnt signaling in BMSCs under pressure.
CONCLUSION
Wnt signaling participates in the pressure-promoted chondrogenesis of the BMSCs co-cultured with PRF, with canonical and noncanonical pathways playing distinct roles during the process.

【Objective】 To investigate the active ingredients of Zizyphi Spinosae Semen (ZSS) in relieving benzodiazepine (BDZ) dependence and its molecular mechanism based on the integrated Traditional Chinese Medicine and chemical drugs idea of "enhancing effect and reducing toxicity" via the approach of network pharmacology and the technique of molecular dynamics simulation. 【Methods】 First, literature search was undertaken to find the main components of ZSS. Then, the major effective constituents of ZSS in relieving BDZ dependence and its target of action were explored on the basis of network pharmacology and molecular docking. Finally, the relationship between core components of ZSS and key proteins was further verified through the technique of molecular dynamics simulation. 【Results】 After literature search, a total of 24 chemical components in ZSS were found to act on 731 targets. Through establishing the network of "ingredients-targets-pathways" , topology analysis was performed to obtain nine core components such as linoleic acid, palmitic acid, oleic acid, tetradecanoic acid, spinosin, oleanolic acid and jujuboside A, as well as five key targets including AR, PTGS2, PPARG, RXRA and CYP19A1. Bioinformation enrichment analysis was made to obtain critical pathways such as calcium signaling pathway, cAMP signaling pathway, IL-17 signaling pathway and TNF signaling pathway. The results of molecular docking revealed that there was a good combination between core components of ZSS and key targets, and it was mainly dominated by hydrogen bonding. Furthermore, the molecular dynamics simulation experiments indicated that the combinations between jujuboside A and RXRA, oleanolic acid and RXRA, spinosin and PPARG were stable, and these three active ingredients played an important role in improving BDZ dependence. 【Conclusion】 The active components in ZSS may exert multi-target and multi-pathway intervention effects on BDZ dependence by means of processes such as immunoregulation, anti-anxiety, and anti-insomnia.
