Objective:To investigate the effect of HSM on the immunoreaction and renal fibrosis in mice with cecal ligation and puncture (CLP).Methods: Renal fibrosis was induced by CLP;mice were divided into three groups,including sham group (sham,n =5),model group (CLP,n =11),therapy group (HSM,n =11).HSM extract [200 mg/(kg?d)] was orally administered to HSM group2 hour before surgery and repeated everyday throughout 10 days,while sham group and model group were given the same dose of normalsaline.FACS assay was used to analyze the amount of macrophages ,neutrophils and Treg in PBMC,as well as macrophages in peritonealfluid;we used Q-PCR assay to analyze the expression of inflammatory molecules (IL-1βand TNF-α) and fibrogenic cytokines (TGF-β,MMP9 and TIMP1) from renal sections.Besides,renal sections were subjected to HE stain and immunohistochemical staining with α-SMA and fibronectin.Results: The amount of model group′s macrophages and neutrophils in PBMC,as well as macrophages in theperitoneal fluid were significantly higher than sham group ′s,whereas HSM succeeded in lowering them;contrast to sham group,Tregs′amount of CLP group and HSM group in PBMC had no significant changes .The expression of inflammatory molecules (IL-1βand TNF-α) and fibrogenic cytokines (TGF-β,MMP9 and TIMP1) from CLP group′s renal sections were remarkably improved ,whereas HSM inhibitedthat.The CLP group′s HE results showed obvious renal inflammatory damage ,whereas HSM reduced the histopathologicalterations;contrast to sham group,model group′s expression of α-SMA and fibronectin was remarkably improved,while HSM groupshowed lower expression.Conclusion: HSM extract could regulate immunity response and had effect in improving renal fibrosis .

Objective:To investigate the effect of HSM on the inflammation and pulmonary fibrosis in mice with cecal ligation and puncture ( CLP) . Methods: Both 5 day and 10 day timepoint pulmonary fibrosis were induced by CLP;mice were randomly divided into three groups,including sham group (sham,n=5),model group (CLP,n=11),therapy group (HSM,n=11). HSM extract (200 mg/kg,less than human dose of 0. 27 g/kg) was orally administered to HSM group 2 hour before surgery and repeated everyday, while sham group and model group were given the same dose of normal saline. We used Q-PCR assay to analyze the expression of in-flammatory molecules ( IL-1β and TNF-α) and fibrogenic cytokines ( TGF-β, MMP9 and TIMP1 ) from lung tissues , we used FACS assay to analyze the amount of Th1 cells in PBMC and spleen sections,as well as Treg in spleen sections. Besides,lung sections were subjected to HE stain and immunohistochemical staining withα-SMA and fibronectin. Results:The amount of model group's Th1 cells in PBMC and spleen sections,as well as Treg in spleen sections were significantly lower than sham group's,whereas HSM succeeded in raising them. By day 5, the expression of inflammatory molecules IL-1β and fibrogenic cytokines (TGF-β,MMP9 and TIMP1) from CLP group's lung sections were remarkably improved,by day 10,the expression had decreased but was higher than sham group's;HSM inhibited these cytokines' expression. The expression of TNF-α of CLP group and HSM group had no significant changes. The CLP group's HE results showed obvious pulmonary inflammatory damage,by day 10,the situation had improved,whereas HSM reduced the histopathologic alterations;contrast to sham group,model group's expression of α-SMA and fibronectin was remarkably improved,while HSM group showed lower expression. Conclusion: HSM extract can suppress inflammation, balances immune system and relieves pulmonary fibrosis.

Objective:To clarify the medical security plan and its practical effects at the main venue of the 19th Hangzhou Asian Games.Methods:The plan described the medical security implementation plan of the main venue of the 19th Asian Games in Hangzhou (organizational management and operation mechanism, medical security operation system, standardized training and support processes, application of Asian Games intelligent first aid security system, and so on). And through high-facticity simulation verify the operation effect of the main venue's medical support (team mode and response time). Finally, the feasibility and effectiveness of the medical security program verified through the effect of medical services (quantity, disease types, transfers, etc.) during the Asian Games and Asian Paralympic Games.Results:The medical security team of the main venue of the 19th Hangzhou Asian Games included the management team and the operation team, of which consisted of 44 medical staffs (22 doctors and 22 nurses); and were deployed to 16 different security positions. It was also accompanied with 16 volunteers to assist medical staff to transport patients. In addition, a total of 300 medical observers were enrolled in audience area to assist rapid identification, intervention, and collaborative diagnosis and treatment with the medical team. Medical security teams were arranged to cover all the audience areas who can arrive at the patient's area within 2 minutes after receiving orders, transfer the patient to the ambulance’s site in 8 minutes, and transport the patient to a designated hospital within 10-20 minutes. During the Asian Games and Asian Paralympic Games, the medical-care team treated a total of 3 742 patients, including 9 patients transported from medical service sites of the audience area to the stadium infirmary, as well as 83 patients referred to the designated hospital.Conclusions:The medical security implementation plan for the main venues of the Asian Games provides good medical security for the Asian Games and Asian Paralympic Games. It also provides theoretical and practical experience for the development of the medical security system for international events in future.

OBJECTIVE To study the pharmacological basis of Schisandra chinensis in the treatment of allergic asthma. METHODS The common components of 10 batches of S. chinensis from different habitats were analyzed by UPLC-Q-TOF-MS/MS. Furthermore, the allergic asthma model was established by intraperitoneal injection of ovalbumin (OVA) and aluminum hydroxide for stimulation combined with atomization exitation; general behavioral observation and the contents of interferon γ (IFN-γ), interleukin-4 (IL-4) and immunoglobulin E (IgE) in serum were taken as criteria for evaluating the therapeutic effect of S. chinensis from different habitats in the treatment of allergic asthma. Correlation coefficients between common peak area and efficacy evaluation index of each batch of medicinal material were analyzed through grey correlation degree and Pearson correlation analysis. RESULTS A total of 21 common components were identified in 10 batches of S. chinensis from different habitats. After administration of S. chinensis, symptoms such as shortness of breath, sneezing and curling of rats were alleviated. In addition, the content of IFN-γ was significantly increased while the contents of IL-4 and IgE in serum were distinctly decreased (P<0.01). Grey correlation analysis showed that 11 common components had high correlation coefficients with IFN-γ, IL-4 and IgE (rˉ>0.8). Pearson correlation analysis showed that 8 components were significantly positively correlated with the content of IFN-γ (P< 0.05), and 9, 8 components were significantly negatively correlated with the content of IL-4 and IgE (P<0.05). Based on the results of grey correlation degree and Pearson correlation analysis, 7 components such as peak 3, 4, 6, 7, 9, 19 and 20, were highly related to S. chinensis in the treatment of allergic asthma. CONCLUSIONS Schisandrol A, schisandrin B, schisandrin C, gomisin M2, gomisin J, pregomisin and angeloylgomisin H are the potential pharmacodynamic substance basis of S. chinensis in the treatment of allergic asthma.
