Mechanism of Anti-tuberculosis Particles （Kanglao Granule） Based on Network Pharmacology and Experimental Research / 中国实验方剂学杂志

ObjectiveTo explore the potential anti-tuberculosis mechanism of Kanglao granule through network pharmacology. MethodThe active components of Kanglao granule were retrieved from related databases and the potential targets of the components from SwissTargetPrediction. Targets of the tuberculosis were screened from GeneCards and National Center for Biotechnology Information （NCBI）， and the anti-tuberculosis targets of the prescription were further identified. STRING and Cytoscape 3.8.0 were employed to construct the Chinese medicinal-disease target-signaling pathway network and screen core targets. Then gene ontology （GO） term enrichment and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment were performed. Finally， AutoDock Vina was used for molecular docking between the active components of the prescription and key proteins and Western blotting for verifying the interaction between them. ResultA total of 29 important chemical components in the prescription were screened out， including β-sitosterol， sesamin， and kaempferol. A total of 28 key anti-tuberculosis targets were retrieved， such as protein kinase B1 （Akt1）， epidermal growth factor receptor （EGFR）， hypoxia inducible factor-1A （HIF-1A）， proto-oncogene tyrosine-protein kinase （SRC）， and matrix metalloproteinase-9 （MMP-9）. Bioinformatics analysis showed the 28 targets were involved in 41 GO terms such as oxygen metabolism， nucleic acid transcription， and metabolic enzyme pathway， and 28 key KEGG pathways， including Mycobacterium tuberculosis signaling pathway and phosphatidylinositol 3 kinase/protein kinase B pathway. Molecular docking results showed that Akt1 had the strongest binding affinity to sesamin. In vitro experiment indicated that sesamin inhibited the growth of M. tuberculosis by suppressing the phosphorylation of Akt1. ConclusionKanglao granule improved the sterilization level and immune response through multi-component， multi-target， and multi-pathway interactions， thereby achieving therapeutic effect on tuberculosis. Akt1 is one of the important targets involved in the treatment of tuberculosis.

Oxygen Metabolism-induced Stress Response Underlies Heart-brain Interaction Governing Human Consciousness-breaking and Attention / 神经科学通报·英文版

Neuroscientists have emphasized visceral influences on consciousness and attention, but the potential neurophysiological pathways remain under exploration. Here, we found two neurophysiological pathways of heart-brain interaction based on the relationship between oxygen-transport by red blood cells (RBCs) and consciousness/attention. To this end, we collected a dataset based on the routine physical examination, the breaking continuous flash suppression (b-CFS) paradigm, and an attention network test (ANT) in 140 immigrants under the hypoxic Tibetan environment. We combined electroencephalography and multilevel mediation analysis to investigate the relationship between RBC properties and consciousness/attention. The results showed that RBC function, via two independent neurophysiological pathways, not only triggered interoceptive re-representations in the insula and awareness connected to orienting attention but also induced an immune response corresponding to consciousness and executive control. Importantly, consciousness played a fundamental role in executive function which might be associated with the level of perceived stress. These results indicated the important role of oxygen-transport in heart-brain interactions, in which the related stress response affected consciousness and executive control. The findings provide new insights into the neurophysiological schema of heart-brain interactions.

Intestinal dysfunction of spinal cord injury treated with moxibustion: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the clinical effect on intestinal dysfunction of spinal cord injury (SCI) between the comprehensive therapy of moxibustion (moxibustion for opening the governor vessel and regulating the spirit) and rehabilitation training and the simple treatment with rehabilitation training.@*METHODS@#A total of 60 patients with intestinal dysfunction of SCI were randomized into a comprehensive therapy group and a rehabilitation group, 30 cases in each one (3 cases were dropped out in each group). On the base of the routine western medicine treatment and rehabilitation training, the bowel training and rectal function training were provided, once a day in the rehabilitation group. In the comprehensive therapy group, on the base of the treatment as the rehabilitation group, the moxibustion was exerted at Yaoyangguan (GV 3), Mingmen (GV 4), Zhiyang (GV 9), Dazhui (GV 14) and Baihui (GV 20), etc, once a day, 30 min each time. In both groups, the treatment for 4 weeks was as one course and 3 courses of treatment were required. Separately, before treatment, after 4, 8 and 12 weeks of treatment, the scores of neurogenic bowel dysfunction (NBD) and World Health Organization quality of life scale (WHOQOL-BREF) were observed and the clinical effect was evaluated after 12 weeks of treatment.@*RESULTS@#After treatment, the total effective rate was 88.9% (24/27) in the comprehensive therapy group, which was higher than 74.1% (20/27) in the rehabilitation group (<0.05). After 4, 8 and 12 weeks of treatment, NBD scores were all reduced obviously as compared with those before treatment in the two groups (all <0.01). After 8 and 12 weeks of treatment, NBD scores in the comprehensive therapy group were lower than the rehabilitation group (both <0.05). After 4, 8 and 12 weeks of treatment, the scores of all of the domains (psychology, physiology, social relations and environment) in WHOQOL-BREF were higher than those before treatment in the two groups (all <0.01). After 4 weeks of treatment, the scores in the psychology and physiology domains in the comprehensive therapy group were higher than the rehabilitation group (all <0.05). After 8 and 12 weeks of treatment, the scores of all of the domains in the comprehensive therapy group were higher than the rehabilitation group (all <0.05).@*CONCLUSION@#The comprehensive treatment of moxibustion and rehabilitation training achieves the better effect on intestinal dysfunction of SCI than the simple rehabilitation training and greatly improves the quality of life in SCI patients.

Comparative Analysis of Effect of Houpu Wenzhongtang Combined Decoction and Simple Decoction on Urine Metabonomics of Rats with Deficiency-cold of Spleen and Stomach / 中国实验方剂学杂志

Objective:To study the effect of combined decoction and single decoction of Houpu Wenzhongtang on rats with deficiency-cold of spleen and stomach from the perspective of metabonomics, to find out the relevant potential biomarkers and metabolic pathways, and to explore the similarities and differences between the combined decoction and single decoction, so as to provide reference for the feasibility analysis of replacing traditional decoction with single dispensing granule of this formula. Method:SD rats were randomly divided into normal group, model group, Houpu Wenzhongtang combined decoction group and simgle decoction group. Rats in the normal group were given distilled water by intragastric administration, rats in the other three groups were given cold vinegar at 4 ℃ in the morning and refined lard in the afternoon for 10 days (the dosage of 10 mL·kg-1). After the model was successfully established, rats in the combined decoction group and the single decoction group were given corresponding decoction with dosage of 1.8 g·kg-1 (according to the amount of crude drugs), once a day for 7 days. Ultra-high liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MS) technique was used to analyze the small molecular endogenous metabolites in urine. Orthogonal partial least squares-discriminant analysis (OPLS-DA) and principal component analysis (PCA) were used to compare the changes of differential metabolites among the normal group, model group, Houpu Wenzhongtang combined decoction group and single decoction group, and the differential metabolites were introduced into Kyoto Encyclopedia of Genes and Genomes (KEGG) for metabolic pathway analysis. Result:Compared with the model group, the Houpu Wenzhongtang combined decoction group and single decoction group jointly regulated 13 potential biomarkers, including phosphatidylcholine(PC), lysophosphatidic acid(LysoPA) and cholic acid, etc. They played a role in treating deficiency-cold of spleen and stomach by influencing metabolic pathways such as glycerophospholipid metabolism, glycerolipid metabolism, phosphatidylinositol signaling system and so on. The combined decoction and single decoction of Houpu Wenzhongtang could obviously restore the body weight, motilin and gastrin contents of rats with deficiency-cold of spleen and stomach to normal levels. Conclusion:According to biochemical indexes, there is no obvious difference between combined decoction and single decoction of Houpu Wenzhongtang, but according to metabonomics, the combined decoction may be slightly better than the single decoction. The research shows that it is feasible to replace traditional decoction with single dispensing granule of Houpu Wenzhongtang in clinical application.

Comparison of functional parameters of small airways between patients with typical asthma and cough-variant asthma / 南方医科大学学报

<p><b>OBJECTIVE</b>To compare the functional parameters of the small airways and clinical characteristics between patients with typical asthma (TA) and cough-variant asthma (CVA).</p><p><b>METHODS</b>Forty-three newly diagnosed asthmatic patients were enrolled, including 15 with TA and positive bronchial provocation test [TA BPT(+)], 12 with TA and positive bronchial dilation test [TA BDT(+)] and 16 with CVA, and 27 healthy subjects served as the control group. All the subjects were required to complete data acquisition, asthma control test, asthma control test scale, fractional exhaled nitric oxide, airway resistance and pulmonary function tests, BPT or BDT.</p><p><b>RESULTS</b>The interval from onset to a definite diagnosis of TA BDT(+) was longer than that of TA BPT(+), while that of CVA was the shortest (P=0.022). The pulmonary functional parameters of TA BDT (+) was significantly lower than those of the other 3 groups (P<0.05). MMEF, MEF, MEF, and MEFin patients with TA BDT(+), TA BPT(+) and CVA were significantly lower than those in the control group (P<0.01). The resonant frequency, respiratory impedance, resistance at 5 Hz, resistance at 20 Hz, and reactance at 5 Hz were significant higher in patients with TA BDT (+) than in the control subjects, while these parameters showed no significant differences among TA BPT (+), CVA and control groups. The airway resistance in TA BPT(+), CVA, and control groups increased after BPT, and the patients with TA BPT(+) showed greater changes in airway resistance than those in CVA and control groups. In CVA patients, FeNO showed a strong positive correlation with respiratory impedance (r=0.523, P=0.038), resistance at 5 Hz (r=0.542, P=0.030), and resistance at 20 Hz (r=0.524, P=0.037), and the airway responsiveness showed a strong positive correlation with resistance at 20 Hz (Rho=-0.512, P=0.043).</p><p><b>CONCLUSION</b>CVA is the early stage of TA, and CVA, TA BPT(+), and TA BDT(+) may represent different stages of asthma. Uncontrolled, prolonged CVA may evolve into TA BPT (+), whose further progression can cause damages of the pulmonary function and small airway function and leads eventually to TA BDT (+).</p>

AIM:To evaluate the effect of α2-macroglobulin(α2M) against X-ray induced obstacle on osteo-genic differentiation of human bone marrow mesenchymal stem cells(hBMMSCs). METHODS:hBMMSCs were cultured in vitro. The 4th generation of hBMMSCs was irradiated with 8 Gy X-ray,then induced osteogenic differentiation and trea-ted with different concentrations of α2M(0.5 and 1.0 g/L). The alkaline phosphatase(ALP) activity and the mRNA ex-pression of runt-related transcription factor-2 (RUNX2) were detected on day 7 after osteogenic induction. The protein ex-pression of osteoglycin (OGN) was evaluated by Western blot on day 14 after osteogenic induction. The formation of calci-um nodules was detected by alizarin red staining on day 21 after osteogenic induction. The activity of superoxide dismutase (SOD) and the protein expression of MnSOD of irradiated hBMMSCs with 8 Gy X-ray were determined at 24 h after α2M treatment. RESULTS:Compared with 8 Gy X-ray group,the activity of ALP,the mRNA expression of RUNX2,the pro-tein expression of OGN and MnSOD,as well as SOD activity were higher than those in the hBMMSCs treated with α2M at 0.5 and 1.0 g/L after 8 Gy X-ray irradiation,and the calcium nodules were also increased. CONCLUSION:α2M signifi-cantly improves the osteogenic differentiation ability,the SOD activity and MnSOD protein expression of hBMMSCs after ra-diation injury.
