ABSTRACT
ObjectiveTo explore the mechanism of Cervi Cornu Pantotrichumin in the treatment of osteoarthritis by network pharmacology. MethodThe active ingredients and the corresponding targets of Cervi Cornu Pantotrichumin were screened out by a Bioinformatics Analysis Tool of Molecular mechANism of Traditional Chinese Medicine （BATMAN-TCM）. The targets related to osteoarthritis were obtained through GeneCards and Online Mendelian Inheritance in Man （OMIM）. The targets corresponding to the active ingredients and those related to osteoarthritis were intersected to reveal the common targets， and STRING was adopted to build a protein-protein interaction （PPI） network. DAVID was used for gene ontology （GO） annotation and Kyoto encyclopedia of genes and genomes （KEGG） pathway enrichment on the anti-osteoarthritis targets of Cervi Cornu Pantotrichumin， and R x64 3.6.3 was employed to produce the advanced bubble charts of GO terms and KEGG pathways. Cytoscape 3.7.2 was used to establish the “Chinese medicinal herb-active ingredient-target-signaling pathway” network. In vitro experiments were performed to detect the viability of RAW 264.7 cells exposed to oxidative stress and the tumor necrosis factor （TNF）-α level in RAW 264.7 cells with inflammation under the treatment by Cervi Cornu Pantotrichumin. ResultA total of 20 active ingredients of Cervi Cornu Pantotrichum were obtained， of which ceramide， 6'-O-β-D-glucosylgentiopicroside， cerebroside， oleuropein， sphingomyelin， and cholesterol ferulate did not meet the screening conditions. Therefore， a total of 14 active ingredients were finally screened out， and 303 and 3 093 targets of active ingredients and osteoarthritis were respectively obtained. The two target sets were taken to intersect， which revealed 92 common targets. GO annotation and KEGG pathway enrichment showed that the targets were mainly involved in redox process， positive regulation of RNA polymerase Ⅱ promoter transcription， inflammatory response， protein synthesis， osteoclast differentiation， TNF signaling pathway， signaling pathways in cancer， mammalian target of rapamycin （mTOR） signaling pathway， mitogen-activated protein kinase （MAPK） signaling pathway， and cyclic adenosine monophosphate （cAMP） signaling pathway. The results of in vitro experiments showed that a certain concentration of protein in Cervi Cornu Pantotrichum significantly increased the viability of RAW 264.7 cells exposed to H2O2-induced oxidative damage （P<0.05， P<0.01） and reduced the level of TNF-α in the RAW 264.7 cells experiencing lipopolysaccharide （LPS）-induced inflammation （P<0.05）. ConclusionBased on the network pharmacology method， the mechanism of the multi-component， multi-target and multi-pathway treatment of OA by antler antler was explained， and the anti-inflammatory and antioxidant activities of antler antler were confirmed， which provided theoretical guidance and scientific basis for further research on the treatment of OA by antler antler.
ABSTRACT
This study aimed to investigate the antidepressant effects of total alkaloids of Fibraurea recisa in HT22 cells damaged by corticosterone (CORT) in vitro and in a mouse model of chronic unpredictable mild stress (CUMS) as well as the underlying mechanisms.In cellular experiments,the viability of CORT-damaged HT22 cells was detected using cell counting kit-8 (CCK-8),and the cell apoptosis was detected by Hoechst 33258 staining.In animal experiments,C57BL/6N mice were randomly divided into the control group,model group,low (100 mg·kg~(-1)),medium (200 mg·kg~(-1)) and high (400 mg·kg~(-1))-dose of total alkaloids of F.recisa groups,and positive control group.After 21 days of CUMS exposure,their depressive behaviors were observed in behavioral and Morris water maze tests.The serum levels of 5-hydroxytryptamine (5-HT),dopamine (DA),and norepinephrine (NE) were assessed by ELISA.The expression levels of apoptosis-related proteins Bcl-2,Bax and cleaved caspase-3 in HT22 cells and mouse hippocampus were detected by Western blot.The results suggested that total alkaloids of F.recisa alleviated the damage of HT22 cells induced by CORT in a dose-dependent manner.The Hoechst 33258 staining uncovered that total alkaloids of F.recisa better reduced the blue spots and inhibited cell apoptosis.The results of animal experiments showed that total alkaloids of F.recisa significantly improved the depression-like behaviors of mice and increased the serum levels of 5-HT,DA and NE as compared with those in the model group.The Western blot assays revealed a significant up-regulation of Bcl-2 protein expression,but an obvious reduction in Bax and cleaved caspase-3protein expression in the total alkaloids of F.recisa group.In conclusion,total alkaloids of F.recisa inhibited depression possibly by regulating the apoptosis-related protein expression or elevating the monoamine neurotransmitter levels in the brain.

Objective To investigate effects of goal-directed fluid therapy on inflammatory cytokines under combined anesthesia.Methods 60 patients undergoing colorectal cancer surgery,aged 60 to 85 years old,which were classified as American Society of Anesthesiology(ASA)classⅡ~Ⅲ,were randomly assigned to Goal-directed fluid therapy group(group G,n = 30)and central venous pressure liquid management group(group C,n = 30). Life sign and BIS indexes were collected at the time points,before surgery(T1),after the start of the operation (T2),one hour after surgery(T3),after the operation(T4).Hemodynamic indexes were recorded.Two milliliter blood sample were phlebotomized for evaluation of TNF-α and IL-6 from each patient at T1,T3,T4.The infusion volume, the amount of bleeding,the operation time,anal exhaust time,and length of postoperative hospital stay were recorded. Results Comparing information between the two groups,infusion volume and colloid had an obvious decrease than that of group C(P<0.05).SVV and CVP of group G were much stable than group C.The levels of TNF-α and IL-6 of group G were lower than those of group C(P<0.01).The length of anal exhaust time and post-operative hospital stay group G were faster than that of group C(P<0.01).Conclusions Goal-directed fluid ther-apy is superior on fluid administration. It can reduce the release of IL-6 and TNF-α. It is beneficial to elderly colorectal cancer patients with hypertension.
ABSTRACT
Objective:To explore anti-platelet/anti-coagulation treatment and their influence on prognosis in advanced aged patients with acute coronary syndrome (ACS)complicated atrial fibrillation (AF)after percutaneous coronary intervention (PCI).Methods:A total of 204 advanced aged ACS + AF patients treated in our heart center were se-lected.All patients received CHA2 DS2 Vasc score assessment,male had score ≥2 scores and female had score ≥3 scores.A total of 160 cases received dual anti-platelet therapy combined anticoagulant treatment of warfarin,and they were randomly divided into low intensity group [n=80,international normalized ratio (INR)remained 1.8~2.3]and high intensity group (n=80,INR remained 2.3~2.8),both groups were followed up for 18 months.Inci-dence rates of major adverse cardiovascular and cerebrovascular events (MACCE),ischemic and hemorrhage events were observed.Results:Both groups were followed up for a mean 18 months,and there were no significant differ-ence in all-cause mortality,incidence rates of MACCE and fatal hemorrhage between two groups,P > 0.05 all.Compared with low intensity group,there were significant rise in incidence rates of severe hemorrhage (3.8% vs. 12.5%),P <0.05.Conclusion:Low intensity warfarin anticoagulant therapy can effectively reduce incidence rates of MACCE and ischemic events,and incidence rate of hemorrhage events is low in advanced aged ACS + AF pa-tients after PCI.
