The present study investigated the effect of active components of Descurainia sophia on allergic asthma and explored the underlying mechanism. SD male rats were randomly divided into a normal group(NC), a model group(M), a D. sophia decoction group(DS), a D. sophia fatty oil group(FO), a D. sophia flavonoid glycoside group(FG), a D. sophia oligosaccharide group(Oli), and a positive drug dexamethasone group(Y). The allergic asthma model was induced in rats by intraperitoneal injection of ovalbumin(OVA) and aluminum hydroxide gel adjuvant(sensitization) and atomization of OVA solution(excitation). After modeling, asthma-related indicators, tracheal phenol red excretion, inflammatory cell levels in the peripheral blood, lung permeability index(LPI), and oxygenation index(OI) of rats were detected. The pathological changes of lung tissues were observed by HE staining. Enzyme-linked immunosorbent assay(ELISA) was used to detect the content of inflammatory factors immunoglobulin E(IgE), interleukin-4(IL-4), and interferon-γ(IFN-γ) in the bronchoalveolar lavage fluid(BALF) and the content of endothelin-1(ET-1) and angiotensin-converting enzyme(ACE) in lung tissue homogenate. The serum content of nitric oxide(NO) was detected by colorimetry. Western blot was employed to determine the protein expression of Toll-like receptor 4(TLR4), nuclear factor κB-p65(NF-κB-p65), phosphorylated NF-κB-p65(p-NF-κB-p65), myosin light chain kinase(MLCK), vascular endothelial cadherin(VE cadherin), connexin 43, and claudin 5, and the mechanism of active components of D. sophia on allergic asthma was explored. As revealed by the results, the M group showed extensive infiltration of inflammatory cells around the bronchus of the lung tissues of the allergic asthma rats, thickened bronchial wall, severely deformed alveolar structure, increased number of wheezes, the content of IgE, IL-4, ET-1, and ACE, inflammatory cells, and LPI, and reduced latency of asthma, tracheal phenol red excretion, IFN-γ, NO content, and OI. After the intervention of the active components of D. sophia, the DS, FO, FG, Oli, and Y groups showed improved asthma-related indicators, tracheal phenol red excretion, and lung tissue lesions in allergic asthma rats, and the effects in the FO and Oli groups were superior. The content of inflammatory factors in BALF was recovered in the DS, FO, and Y groups and the FG and Oli groups. The number of inflammatory cells in rats was reduced in the DS and FO groups, and the FG, Oli, and Y groups to varying degrees, and the effect in the FO group was superior. DS, FO, Oli, and Y reduced ET-1, ACE, and LPI and increased NO and OI. FG recovered NO, ET-1, ACE, LPI, and OI to improve lung epithelial damage and permeability. Further investigation of inflammation-related TLR4/NF-κB pathways, MLCK, and related skeleton protein levels showed that TLR4, NF-κB-p65, p-NF-κB-p65, and MLCK levels were increased, and VE cadherin, connexin 43, and claudin 5 were reduced in the M group. DS, FO, FG, Oli, and Y could reduce the protein expression related to the TLR4 pathway to varying degrees, and regulate the protein expression of MLCK, VE cadherin, connexin 43, and claudin 5. It is inferred that the active components of D. sophia improve lung permeability in rats with allergic asthma presumedly by regulating the TLR4/NF-κB signaling pathway to improve airway inflammation, mediating MLCK and connexin, and regulating epithelial damage.

OBJECTIVE: To observe the effect of Biantie (bian stone plaste) pretreatment on serum level of prolyl hydroxylase domain 2 (PHD2) and hypoxia-inducible factor-1α (HIF-1α) in rats with acute hypobaric hypoxia induced-brain injury, and to explore the possible mechanism of Biantie on preventing brain injury at high altitude. METHODS: Forty-five male SD rats were randomly divided into a blank group, a model group, a Biantie group, a medication group and a Biantie+inhibitor group, 9 rats in each group. The rats in the Biantie group the and the Biantie+inhibitor group were pretreated with Biantie at "Taiyuan" (LU 9), "Neiguan" (PC 6) and "Renying" (ST 9), 2 h each time, once a day; the rats in the medication group were treated with intragastric administration of rhodiola capsule solution (280 mg/kg) for 14 d; the rats in the Biantie+inhibitor group were intraperitoneally injected with the PHD inhibitor dimethyloxalyl glycine (DMOG) at a dose of 40 mg/kg 24 h before the establishment of the model. After the intervention, except for the blank group, the rats in the remaining 4 groups were placed in the oxygen chamber to simulate a high-altitude environment to establish the acute hypobaric hypoxia brain injury model. The arterial blood-gas analysis indexes [blood oxygen saturation (SaO₂), lactic acid (Lac), blood sodium (Na⁺), blood potassium (K⁺)] and brain water content were detected in each group; the histomorphology of cerebral cortex was observed by HE staining; the serum levels of PHD2 and HIF-1α as well as vascular endothelial growth factor (VEGF) were detected by ELISA; the VEGF protein expression in brain tissue was detected by Western blot; the VEGF mRNA expression in brain tissue was detected by real-time fluorescent quantitative PCR. RESULTS: Compared with the blank group, the levels of SaO₂ and Na⁺ in the model group were decreased (P<0.05), while the levels of Lac and K⁺ as well as the water content of brain tissue were increased (P<0.05). Compared with the model group, the level of SaO₂ in the Biantie group and the medication group was increased (P<0.05), while the levels of Lac, K⁺ and the water content of brain tissue were decreased (P<0.05); the level of Na⁺ in the Biantie group was increased (P<0.05). Compared with the Biantie group, the level of SaO₂ in the Biantie+inhibitor group was decreased (P<0.05), and the level of Lac and the water content of brain tissue were increased (P<0.05). In the model group, the cortical tissue cells were loose and disordered, the cortical blood vessels were dilated, and the cells were obviously swollen; the anoxic injury in the Biantie group and the medication group was lighter, and the anoxic injury in the Biantie+inhibitor group was more obvious than that in the Biantie group. Compared with the blank group, the serum PHD2 content in the model group was decreased and the HIF-1α content was increased (P<0.05), and the content of VEGF in serum and VEGF protein and mRNA expressions in brain were increased (P<0.05). Compared with the model group, the content of PHD2 in serum in the Biantie group and the medication group was increased (P<0.05), and the level of HIF-1α was decreased (P<0.05), and the content of VEGF in serum as well as VEGF protein and mRNA expressions in brain were decreased (P<0.05). Compared with the Biantie group, the serum PHD2 content in the Biantie+inhibitor group was decreased and HIF-1α level were increased (P<0.05), and the content of VEGF in serum as well as VEGF mRNA expression in brain were increased (P<0.05). CONCLUSION Biantie at "Taiyuan" (LU 9), "Neiguan" (PC 6) and "Renying" (ST 9) could regulate serum PHD2/HIF-1α to down-regulate VEGF expression, reduce brain edema and enhance anti-hypoxia ability, so as to achieve the purpose of preventing brain injury at high altitude.

Methods:An evidence-based scoping review had been implemented. We had developed the framework and coding approaches for recreational physical activities, rehabilitation exercise and functional improvement for the adults with disabilities based on evidence-based literature review. The literature related to recreational physical activities and rehabilitation exercise of adult with disabilities was searched by subject retrieval method. The retrieval database in Chinese included CNKI and Wanfang database, and the retrieval database in English included PubMed and Web of Science. The retrieval time was from establishment to July 31, 2020. The authors, countries, published time, published journals, research objectives, object of the study and their ages, data collection tool, and the key findings were extracted. Results:A total of 2476 literatures were returned, and 18 of them were enrolled, which were published in 14 countries, and most were published in journals on topics related to medicine, public health, exercise and people with disabilities. They were mainly published from 2010 to 2020, and mainly used questionnaire survey, measurement and interviewing method. There were three typical recreational physical activities: physical fitness activities, skills activities and sports activities, mainly including Taiji Quan, wheelchair basketball, leisure outdoor activities, community recreational sports activities and rehabilitation exercises, etc. According to the framework of ICF, recreational physical activities promote functional rehabilitation for adults with disabilities, including physical functions (b1 mental function; b4 cardiovascular, blood, the function of the immune system and respiratory system; b5 digestion, metabolism and function of the endocrine system; and b7 nerve musculoskeletal function related to movement), and activities and participation (d1 study and application of knowledge; d2 the general tasks and requirements; d4 activity; d5 self-care; d7 interpersonal communication and interpersonal relationship; and d9 community, social and civic life). The evidences showed benefits of improvement in the fields of body mass index, body index, athletic ability, balance ability, and cognitive function. There were more gains at individual levels, including support, coping with stress, self-concept development, life satisfaction, happiness, exercise self-efficacy, health perception, etc. The environmental and personal factors had effects on the performance of activity and participation in recreational physical activities, including e1 products and technologies, e4 attitude, e3 support and interpersonal relationships, e5 service system and policy, as well as attitudes and support of family members and colleagues, interpersonal relationships, social support, transportation, equipment and facilities, and policies. Conclusion:Rehabilitation exercise is an important part of health-related services. We scoped the recreational physical activities and its functional effects for adults with disabilities. The categories and structure of recreational physical activities and rehabilitation exercises were constructed based on ICF. Aligning rehabilitation exercises and relevant factors to ICF, the recreational activities and rehabilitation exercises had been reviewed and discussed and several recommendations for further studies had been drawn.
