Anti-inflammatory effects of Tao Hong Si Wu Tang in mice with lung cancer and chronic obstructive pulmonary disease

BACKGROUND Lung cancer(LC)combined with chronic obstructive pulmonary disease(COPD)is a common combination of comorbidities.Anti-inflammation and modulation of oxidative/antioxidative imbalance may prevent COPD-induced LC,and are also crucial to the treatment of LC combined with COPD.Modern studies have shown that Tao Hong Si Wu Tang(THSW)has vasodilatory,anti-inflammatory,anti-fatigue,anti-shock,immunoregulatory,lipid-reducing,micronutrient-supplementing,and anti-allergy effects.AIM To observe the effects of THSW on COPD and LC in mice.METHODS A total of 100 specific pathogen-free C57/BL6 mice were randomly divided into five groups:Blank control group(group A),model control group(group B),THSW group(group C),IL-6 group(group D),and THSW+IL-6 group(group E),with 20 mice in each group.A COPD mouse model was established using fumigation plus lipopolysaccharide intra-airway drip,and an LC model was replicated by in situ inoculation using the Lewis cell method.RESULTS The blank control group exhibited a clear alveolar structure.The model control and IL-6 groups had thickened alveolar walls,with smaller alveolar lumens,interstitial edema,and several inflammatory infiltrating cells.Histopathological changes in the lungs of the THSW and THSW+IL-6 groups were less than those of the model control group.The serum IL-1β,IL-6,and TNF-αlevels and IL-6R,JAK,p-JAK,STAT1/3,p-STAT1/3,FOXO,p-FOXO,and IL-7R expression levels in lung tissues of mice in the rest of the groups were significantly higher than those of the blank control group(P<0.01).Compared with the model control group,the IL-6 group demonstrated significantly higher levels for the abovementioned proteins in the serum and lung tissues(P<0.01),and the THSW group had significantly higher serum IL-1β,IL-6,and TNF-αlevels and IL-7R expression levels in lung tissues(P<0.01)but significantly decreased IL-6R,JAK,p-JAK,STAT1/3,p-STAT1/3,FOXO,p-FOXO,and IL-7R levels(P<0.01).CONCLUSION THSW reduces the serum IL-1β,IL-6,and TNF-αlevels in the mouse model with anti-inflammatory effects.Its antiinflammatory mechanism lies in inhibiting the overactivation of the JAK/STAT1/3 signaling pathway.

Anti-inflammatory intestinal activity of Combretum duarteanum Cambess. in trinitrobenzene sulfonic acid colitis model

To evaluate the anti-inflammatory intestinal effect of the ethanolic extract (EtOHE) and hexane phase (HexP) obtained from the leaves of Combretum duarteanum (Cd).METHODSInflammatory bowel disease was induced using trinitrobenzenesulfonic acid in acute and relapsed ulcerative colitis in rat models. Damage scores, and biochemical, histological and immunohistochemical parameters were evaluated.RESULTSBoth Cd-EtOHE and Cd-HexP caused significant reductions in macroscopic lesion scores and ulcerative lesion areas. The vegetable samples inhibited myeloperoxidase increase, as well as pro-inflammatory cytokines TNF-α and IL-1β. Anti-inflammatory cytokine IL-10 also increased in animals treated with the tested plant samples. The anti-inflammatory intestinal effect is related to decreased expression of cyclooxygenase-2, proliferating cell nuclear antigen, and an increase in superoxide dismutase.CONCLUSIONThe data indicate anti-inflammatory intestinal activity. The effects may also involve participation of the antioxidant system and principal cytokines relating to inflammatory bowel disease.

Antioxidant,anti-inflammatory and antinociceptive potential of Ternstroemia sylvatica Schltdl.&Cham

ObjectiveTo evaluate the anti-inflammatory, analgesic, antioxidant and acute toxicity of extracts obtained from a successive extraction with solvents of ascending polarity [hexane, hex; chloroform, CHCl3 and ethanol (EtOH)] of Ternstroemia sylvatica Schltdl. & Cham.MethodsThe antioxidant potential was evaluated by 2,2 diphenyl-1-picrylhydrazyl, the ferric reducing/antioxidant power assays and by determining the total phenolic content. The anti-inflammatory and antinociceptive effects were evaluated using the in vivo croton oil-induced ear edema, phorbol 12-myristate 13-acetate induced ear edema, carrageenan-induced paw edema, acetic acid-induced writhing and formalin murine models. The acute toxicity was tested using the Lorke’s method in mice.ResultsThe EtOH extract was the most active for the antioxidant potential tests diphenyl-1-picrylhydrazyl (68.70% inhibition), ferric reducing/antioxidant power [(2 431.30 ± 102.10) mmol Fe2+ and total polyphenols content (215.80 ± 8.50) meqAG/g]. The anti-inflammatory activity was evaluated by topical application of croton oil (2 mg/ear dose) where the EtOH extract showed the strongest activity compared to the control group (45.13% inhibition), whereas in the phorbol 12-myristate 13-acetate model, at the same dose, the CHCl3 extract showed the highest inhibition (42.88%). In the carrageenan induced edema model, the EtOH extract showed a stronger inhibition compared to indomethacin (56.34% and 50.70% at doses of 250 and 500 mg/kg of extract, respectively) during the first hour. Similarly, the same extract showed the highest analgesic activity (30.60% inhibition) in the acetic acid contortion assay, and in the formalin test it showed a greater effect with respect to the control group in both phases.ConclusionsOur work confirms the value of Ternstroemia sylvatica as an important anti-inflammatory and analgesic plant, whose mechanism seems to be associated to its antioxidant effects, and supports its uses in the Mexican traditional medicine.

Peripheral Analgesic and Anti-Inflammatory Effects of Smilax canariensis in an Animal Model

Smilax canariensis Brouss. ex Willd. is an endemic plant of the Canary Islands. Its rhizomes, leaves and stems have been traditionally used in Canary folk medicine to treat a wide variety of conditions including pain. Our objective is to investigate the analgesic and anti-inflammatory activities of different extracts of S. canariensis in Swiss mice, using established biological models for pain and inflammation, such as phenylquinone writhing test, formalin test, tail-flick test and mouse paw edema induced by carrageenan. Oral administration of S. canariensis extracts significantly reduce writhing episodes evoked by phenylquinone injection in a dose-dependent manner;and higher doses result in a reduction of pain similar to or higher than that of the reference drug piroxicam (59.56%;p < 0.01). The extracts also cause a marked dose-dependent inhibition of for-malin-induced pain in the second phase but only minimal inhibition of tail-flick behavior, suggesting that S. canariensis is not a centrally acting analgesic. Finally, in the carrageenan-induced hind paw edema model, the extracts show a moderate anti-inflammatory effect, the most active being the ethyl acetate fraction at 200 mg/kg p.o. (33.33%;p < 0.05). Our results suggest that S. canariensis extracts have clear dose-dependent peripheral analgesic effects, which lends support to the traditional use of this medicinal plant to treat pain associated with inflammatory or other processes.

Antioxidant,Anti-inflammatory,and Antibacterial Activities of Different Extracts from Polygonum capitatum

[Objectives]To investigate the antioxidant,anti-inflammatory and antibacterial activities of different extracts(aqueous,ethanol,ethyl acetate and n-butanol extracts)of Miao medicine Polygonum capitatum.[Methods]Eleven batches of P.capitatum in Guizhou province were collected,and water,ethanol,ethyl acetate and n-butanol extracts were prepared by reflux extraction.Antioxidant activity was determined by radical scavenging capacity of 1,1 diphenyl-2-picyl hydrazine(DPPH),anti-inflammatory activity was screened by lipopolysaccharide(LPS)induced RAW264.7 cells to produce NO,and the minimum inhibitory concentration(MIC)was screened by broth microdilution method.[Results]When the concentration of ethyl acetate extract was 10 mg/L,the scavenging rate of DPPH ranged from 90%to 99%.The(MIC of the ethyl acetate extract against Staphylococcus aureus(SA),Pseudomonas aeruginosa(PA)and Escherichia coli(EC)was 0.18-0.65,0.13-0.82,and 0.15-0.78 g/L,respectively.In the anti-inflammatory activity,ethyl acetate extract inhibited NO production with inhibition rate of 70%.[Conclusions]The ethyl acetate extract and ethanol extract of Miao medicine P.capitatum have strong antioxidant,anti-inflammatory and antibacterial activities.

Medicinal nicotine in COVID-19 acute respiratory distress syndrome,the new corticosteroid

The cholinergic anti-inflammatory pathway(CAP)refers to the anti-inflammatory effects mediated by the parasympathetic nervous system.Existence of this pathway was first demonstrated when acetylcholinesterase inhibitors showed benefits in animal models of sepsis.CAP functions via the vagus nerve.The systemic antiinflammatory effects of CAP converges on theα7 nicotinic acetylcholine receptor on splenic macrophages,leading to suppression of pro-inflammatory cytokines and simultaneous stimulation of anti-inflammatory cytokines,including interleukin 10.CAP offers a novel mechanism to mitigate inflammation.Electrical vagal nerve stimulation has shown benefits in patients suffering from rheumatoid arthritis.Direct agonists like nicotine and GTS-1 have also demonstrated antiinflammatory properties in models of sepsis and acute respiratory distress syndrome,as have acetylcholinesterase inhibitors like Galantamine and Physostigmine.Experience with coronavirus disease 2019(COVID-19)induced acute respiratory distress syndrome indicates that immunomodulators have a protective role in patient outcomes.Dexamethasone is the only medication currently in use that has shown to improve clinical outcomes.This is likely due to the suppression of what is referred to as a cytokine storm,which is implicated in the lethality of viral pneumonia.Nicotine transdermal patch activates CAP and harvests its anti-inflammatory potential by means of an easily administered depot delivery mechanism.It could prove to be a promising,safe and inexpensive additional tool in the currently limited armamentarium at our disposal for management of COVID-19 induced acute hypoxic respiratory failure.

Anti-inflammatory Therapy Progress in Major Adverse Cardiac Events after PCI:Chinese and Western Medicine

Acute coronary syndrome(ACS)is one of the leading causes of death in cardiovascular disease.Percutaneous coronary intervention(PCI)is an important method for the treatment of coronary heart disease(CHD),and it has greatly reduced the mortality of ACS patients since its application.However,a series of new problems may occur after PCI,such as in-stent restenosis,no-reflow phenomenon,in-stent neoatherosclerosis,late stent thrombosis,myocardial ischemia-reperfusion injury,and malignant ventricular arrhythmias,which result in the occurrence of major adverse cardiac events(MACE)that seriously reduce the postoperative benefit for patients.The inflammatory response is a key mechanism of MACE after PCI.Therefore,examining effective anti-inflammatory therapies after PCI in patients with ACS is a current research focus to reduce the incidence of MACE.The pharmacological mechanism and clinical efficacy of routine Western medicine treatment for the anti-inflammatory treatment of CHD have been verified.Many Chinese medicine(CM)preparations have been widely used in the treatment of CHD.Basic and clinical studies showed that effectiveness of the combination of CM and Western medicine treatments in reducing incidence of MACE after PCI was better than Western medicine treatment alone.The current paper reviewed the potential mechanism of the inflammatory response and occurrence of MACE after PCI in patients with ACS and the research progress of combined Chinese and Western medicine treatments in reducing incidence of MACE.The results provide a theoretical basis for further research and clinical treatment.

Contribution to the Valorization of Plants Used in the Management of Rheumatic Diseases in Burkina Faso

Joint pain is a real public health problem. According to recent studies, it is increasingly common in sub-Saharan Africa and represents a cause of greater loss of working days than accidents, heart disease and infections. The aim of this study was to study the pharmacochemical and therapeutic evidence of ten (10) plants used in the management of joint pain by traditional health practitioners in Ouagadougou. We conducted a meta-analysis of the data from December 2018 to September 2019. The anti-inflammatory activity of the ten (10) plants retained the maximum consensus internationally. Trichilia emetica Vahl (35.25%), Guiera senegalensis J.F.G.mel. (31%), Calotropis procera (Ait) Ait.F. (28.29%) and Crescientia cujete L. (25.12%) had more than 25% internationally reliability for their effects on joint pain. The structural analogy between conventional drugs and the molecules found in these plants has been confirmed. Additional studies should be carried out in order to improve and secure the use of these plants, which represent a prominent option in the therapeutic offer.

Anti-Inflammatory and Immunoregulatory Effects of Yupingfeng(玉屏风) Powder on Chronic Bronchitis Rats

Objective： To investigate the anti-inflammatory and immunoregulatory effects of Yupingfeng , Powder and its components in rats. Methods： A rat chronic bronchitis （CB） model was developed using lipopolysaccharide （LPS） combined with bacillus Calmette Guerin （BCG）. YPF, simple recipe Astragalus membranaceus （Fisch.） Bge （AM） and Astragalus membranaceus （Fisch.） Bge plus rhizome of Atractylodes macrocepha/a Koidz （AM＋RA） decoction were administered （intragastric administration, once a day for 21 days） to rats, to prevent and treat CB. Immunoregulatory and anti-inflammatory effects of YPF, AM and AM＋RA were tested by serum pharmacology in vitro on splenic lymphocytes of normal rats and alveolar macrophages of CB rats. Results： Inflammation in the pulmonary tissue and the bronchus of CB rats was significantly reduced in the YPF-treatment groups, AM and AM＋RA groups demonstrating the efficacy of YPF. Serum samples collected at different times from rats after administration of YPF, AM and AM＋RA demonstrated increased proliferation of splenic lymphocytes with area under the effect curve （AUE） of 552.6%, 336.3% and 452.0%, respectively. Treatment of alveolar macrophages with serum samples in YPF, AM or AM＋RA group inhibited interleukin-8 （IL-8） in the cell culture media, and the effect was much better in the YPF group compared with AM or AM＋RA group, with a higher maximal effect （Emax, P〈0.05） and larger AUE （P〈0.01 and P〈0.05）. Moreover, serum from rats treated with AM or AM＋RA had similar efficacy, while the efficiency was lower than that treated with YPF. Conclusion： YPF demonstrated anti-inflammatory and immunoregulatory effects in a rat model of CB, and time- dependent relationships were demonstrated in vitro.

Qualitative phytochemical screening and evaluation of anti-inflammatory, analgesic and antipyretic activities of Microcos paniculata barks and fruits

OBJECTIVE： The main objectives of this study were to qualitatively evaluate the profile of phytochemical constituents present in methanolic extract of Microcos paniculata bark（BME） and fruit（FME）, as well as to evaluate their anti-inflammatory, analgesic and antipyretic activities.METHODS： Phytochemical constituents of BME and FME were determined by different qualitative tests such as Molisch’s test, Fehling’s test, alkaloid test, frothing test, Fe Cl3 test, alkali test, Salkowski’s test and Baljet test. The anti-inflammatory, analgesic and antipyretic activities of the extracts were evaluated through proteinase-inhibitory assay, xylene-induced ear edema test, cotton pellet-induced granuloma formation in mice, formalin test, acetic acid-induced writhing test, tail immersion test and Brewer’s yeastinduced pyrexia in mice.RESULTS： M. paniculata extracts revealed the presence of carbohydrates, alkaloids, saponins, tannins, flavonoids and triterpenoids. All of the extracts showed significant（P〈0.05, vs aspirin group） proteinaseinhibitory activity, whereas the highest effect elicited by plant extracts was exhibited by the BME（75.94% proteinase inhibition activity） with a half-maximal inhibitory concentration（IC50） of 61.31 μg/m L. Each extract at the doses of 200 and 400 mg/kg body weight showed significant（P〈0.05, vs control） percentage inhibition of ear edema and granuloma formation. These extracts significantly（P〈0.05, vs control） reduced the paw licking and abdominal writhing of mice. In addition, BME 400 mg/kg, and FME at 200 and 400 mg/kg showed significant（P〈0.05, vs control） analgesic activities at 60 min in the tail immersion test. Again, the significant（P〈0.05, vs control） post-treatment antipyretic activities were found by BME 200 and 400 mg/kg and FME 400 mg/kg respectively.CONCLUSION： Study results indicate that M. paniculata may provide a source of plant compounds with anti-inflammatory, analgesic and antipyretic activities.

Protective Effects of Xiongshao Capsule(芎芍胶囊) on Anti-inflammatory Function of High-Density Lipoprotein in AnAtherosclerosis Rabbit Model

Objective： To observe the effects of Xiongshao Capsule（芎芍胶囊, XSC） on anti-inflammatory properties of high-density lipoprotein（HDL）, myeloperoxidase（MPO） and paraoxonase 1（PON1） in serum of atherosclerosis（AS） rabbit model and explore the anti-inflammatory protective effects of XSC on HDL. Methods： Sixty rabbits were randomized into the control, the model, XSC low-, medium-and high-dose（Rhizoma Chuanxiong ＋ Radix Paeoniae rubra ： 0.6＋0.3, 1.2＋0.6, 2.4＋1.2 g·kg-1·day-1, respectively）, and simvastatin（1 g·kg-1·day-1） groups. The model rabbits were fed with high-fat diet and respective drugs for 15 weeks. The blood and thoracic aortas samples were collected at the end of 15 weeks. The levels of serum MPO and PON1 as well as total cholesterol（TC） and free cholesterol（FC） in aorta wall cells were tested by enzyme linked immunosorbent assay. Results： TC and FC in the model group were significantly higher than those in the control group（P〈0.01）. Compared with the model group, TC and FC in the XSC groups were significantly lower（P〈0.05 or P〈0.01）, so was simvastatin group（P〈0.01）. There was no significant difference in PON1 level between groups（P〉0.05）, even between model and control groups（P〉0.05）. The serum MPO level in the model group was significantly higher than that in the control group（P〈0.05）, which was significantly lower in XSC groups as well as simvastatin group（P〈0.05 or P〈0.01）, and no difference was found between XSC groups and simvastatin group（P〉0.05）. Conclusions： XSC can reduce the serum MPO level in AS rabbits to protect the anti-inflammatory function of HDL, maintaining the normal lipid transport function. TC and FC levels in aorta cells decline, and this process initiated by XSC plays an anti-AS role.

Inquiry of analgesic and anti-inlfammatory activities ofXanthosoma sagittifolium L.:An effective medicinal plant

Objective:To examine the analgesic and anti-inflammatory activities ofXanthosoma sagittifolium L. (X. sagittifolium) leaves. <br> Methods: The fresh leaves ofX. sagittifolium were extracted with methanol followed by fractionation using ethyl acetate fraction (EAF),n-hexane fraction, chloroform fraction and aqueous fraction. The analgesic activity was determined by acetic acid-induced writhing test and tail immersion test using Swiss albino male mice. Carrageenan-induced paw edema test was used to resolve the anti-inflammatory activity using Wistar albino male rats. <br> Results: The results displayed that among these four samples,EAF had maximum analgesic efficacy (P < 0.001) measured by acetic acid-induced writhing test (71.37%). In case of tail immersion test,EAF also exerted maximum activity (5.03 s,P < 0.001) at 180 min compared ton-hexane fraction, chloroform fraction and aqueous fraction at maximum concentration. In case of anti-inflammatory test,EAF remained ascendancy in its activity (P < 0.001) and it inhibited 72.92% of paw edema at maximum concentration at 180 min with respect to remaining fractions. <br> Conclusions:The above evidences suggest thatEAF ofX. sagittifolium leaves is a potential source of natural compounds having analgesic and anti-inflammatory activities.
