RESUMEN
Aim To study the protective effect of Qingjie HuaGong decoction ( QJHGD) for severe acute pancreatitis ( SAP ) model rats induced by cerulein based on TLR4/NF-kB/MYD88 pathway.Methods The effective component groups and potential targets of QJHGD were collected by network pharmacology method , and we constructed the component-target network.The GO and KEGG of important targets were enriched and analyzed by metascape database, and we selected the targeted pathways related with SAP inflammation mechanism.The rat model of severe acute pancreatitis was established by cerulein combined with lipopolysac- charide, followed by QJHGD gavage.Pancreatic tissues were observed by hematoxylin and eosin staining.We verified the therapeutic effect of QJHGD on SAP rats and the regulatory effect on TLR4/NF-kB/MyD88 target pathway, by Enzyme linked immunosorbent and immunohistochemistry methods.Results A total of 105 active components and 148 key targets for SAP were screened; KEGG was enriched 320 different channels including toll like receptor and NF-kB classical pathways.Animal experiments showed that QJHGD harl protective changes in pancreatic pathological tissues, which was observed by HE staining; QJHGD reduced amylase, lipase, 1L-6 and TNF-a in SAP rat serum, inhibiting the positive expression of key proteins on TLR4/N F- kB/MyD88 inflammatory transduction j j pathways.Conclusion The mechanisms of QJHGD protecting pancreatic injury of SAP rat may be related to reducing the expression of key proteins on TLR4/ NF-kB/MvD88 pathway.
RESUMEN
Aim To analyze the molecular mechanism of rhubarb in the treatment of aeute pancreatitis ( AP) by network pharmacology and molecular docking.Methods TCMSP,TCMID and Swiss target predic¬tion databases were used to screen the active compo¬nents and targets of rhubarb,and genecards and OMIM databases were used to screen the targets of AP.Then the active ingredient drug target network of rhubarb and theactive ingredient disease target network of rhubarb for AP were constructed by using Cytoscape software.PPI network was constructed in string database, and go and KEGG enrichment analysis was performed in metascape database and R language.Finally,molecular docking was used to verify the possibility of binding the core active components to the core target.Results A total of 192 active components and 1 882 AP targets were obtained.The first three active components of rhubarb in the treatment of AP were beta sitosterol, aloe emodin and eupatin.The core target of rhubarb in the treatment of AP was hsp90aal.Go enrichment analysis focused on reaction to toxic substances, while KEGG enrichment analysis was significantly enriched in p53 signaling pathway closely related to AP.Molecular docking showed good binding and stable conformation.Conclusions Rhubarb can affect the expression of AP related genes and proteins through p53 signaling pathway, thereby inhibiting cell apoptosis and allevia¬ting the inflammatory injury of AP.
RESUMEN
<p><b>OBJECTIVE</b>To find out an effective therapy for obesity induced by antipsychotic agents.</p><p><b>METHODS</b>One hundred and one cases of obesity who were being treated with antipsychotic agents were randomly divided into an observation group and a control group. The observation group were treated with electroacupuncture at Quchi (LI 11), Zusanli (ST 36), Fenglong (ST 40), Shangjuxu (ST 37) and Xiajuxu (ST 39), once a day for 8 weeks; and no treatment was given to the control group. The Brief Psychiatric Rating Scale (BPRS) was used for assessment of therapeutic effect and the Treatment Emergent Symptom Scale (TESS) for adverse effects.</p><p><b>RESULTS</b>The clinically effective rate of the observation group (54.9%) was superior to the control group (10.0%) with a significant difference between the two groups (P<0.05). The BPRS score-reducing rate was 24.92% and 28.62% in the both groups respectively, and with no adverse effects.</p><p><b>CONCLUSION</b>Electroacupuncture has a good therapeutic effect on obesity induced by antipsychotic agents, and it improves the patient's compliance with no adverse effect.</p>
