Yes-associated protein ameliorates tumor necrosis factor-α-induced epithelial barrier dysfunction by affecting the F-actin / 中国小儿急救医学

Objective:To investigate the protective role of Yes-associated protein(YAP)in intestinal epithelial barrier injury.Methods:The intestinal epithelial barrier model was established by culturing human colorectal adenocarcinoma cell line Caco-2 cells, which were divided into four groups: control group, Caco-2 monolayers did not receive any treatment; recombinant human tumor necrosis factor-α(rhTNF-α)group, 100 μg/L of rhTNF-α was added to Caco-2 monolayers; vector+ rhTNF-α group, Caco-2 monolayers were first added with control plasmid pcDNA3.1-vector, and 100 μg/L rhTNF-α was added 24 hours later; YAP+ rhTNF-α group, Caco-2 cells with barrier construction were first added with pcDNA3.1-YAP, and 100 μg/L rhTNF-α was added 24 hours later.Realtime-PCR and Western blot were used to evaluate YAP mRNA and protein expression level.Epithelial permeability was assayed by trans-epithelial electrical resistance(TEER)and fluorescein isothiocyanate-dextran 40(FD-40 flu). Cellular distribution of F-actin was assayed by immunofluorescence staining.Results:Compared with control group[(607.3±29.3)Ω·cm 2], TEER of rhTNF-α group[(265.3±32.7)Ω·cm 2] decreased, while TEER of YAP+ rhTNF-α group[(387.0±18.7)Ω·cm 2]increased compared with rhTNF-α group, the differences were statistically significant( P<0.001). The FD-40 flux of rhTNF-α(22.7%±0.5%) group was higher than that of the control group(6.3%±0.9%), while the FD-40 flux of Yap + rhTNF-α group(12.2%±0.8%) was lower than that of rhTNF-α group, the differences were statistically significant( P<0.001). Immunofluorescence staining showed that compared with the control group, the cytoskeletal F-actin fiber dense spot decreased in rhTNF-α group, and some cells showed obvious trans-cellular stress fiber structure, while the peripheral actin band was clear in YAP+ rhTNF-α group, and the intracellular stress fiber decreased.YAP+ TNF-α group appeared as a clear, peripheral actin ribbon with a decrease in cytoplasmic stress fibres. Conclusion:YAP overexpression significantly inhibits TNF-α induced decline of TEER, and increases of FD-40 flux and F-actin rearrangement of Caco-2.YAP could ameliorate TNF-α induced intestinal epithelial barrier injury by regulating cytoskeleton F-actin.

A study on keloid fibroblast induced THP-1 derived macrophage polarization and inflammatory factor TNF-αexpression and its feedback effect / 中华医学美学美容杂志

Objective:To investigate the effect of keloid fibroblasts on the polarization and expression of inflammatory factors of M0 macrophages and possible mechanisms, and provide theoretical basis for new targets for keloid therapy.Methods:Keloids, normal skin tissues and paraffin specimens from patients undergoing plastic surgery in the First Affiliated Hospital of Sun Yat-sen University from November 2020 to September 2021 were collected, and fibroblasts of keloids and normal skins were isolated and co-cultured with M0 cells formed form THP-1 by phorbol ester (PMA)-stimulation to detect the expression of macrophage polarization markers and cytokines. Besides, keloid fibroblasts were treated with exogenous tumor necrosis factor-α(TNF-α) to detect its effect on the proliferation and extracellular matrix expression.Results:Macrophages were dominated by CD163 + (M2) in keloid tissues. Moreover, M0 cells expressed more TNF-α when co-cultured with keloid fibroblasts, compared with those with normal skin fibroblasts, in which, the positive staining rates of TNF-α were 19.32% and 29.52% respectively by flow cytometry. Furthermore, the proliferation was promoted and the expression of extracellular matrix proteins (COL3A1 and FN1)and Vimentin were upregulated in keloid fibroblasts under TNF-α stimulation. However, there was no significant difference in the expression of polarization surface markers CD86 and CD163 in macrophages, when co-cultured with keloid fibroblasts or normal skin fibroblasts. Conclusions:Keloid fibroblasts promote the expression of TNF-α in macrophages, which in turn promotes the proliferation and extracellular matrix secretion of keloid fibroblasts.

Huangqin Decoction Attenuates DSS-Induced Mucosal Damage and Promotes Epithelial Repair via Inhibiting TNF-α-Induced NF-κB Activation / 中国结合医学杂志

OBJECTIVE@#To investigate the protective effect of Chinese herbal formula Huangqin Decoction (HQD) on ulcerative colitis mouse model induced by dextran sulphate sodium (DSS) and human intestinal epithelial cell injury induced by tumour necrosis factor-α (TNF-α).@*METHODS@#In vivo, 30 male C57BL/6 mice were divided into 5 groups using a random number table (n=6 per group), including control, DSS, 5-aminosalicylic acid (5-ASA), HQD low- (HQD-L) and high-dose (HQD-H) groups. The colitis mouse model was established by 3% (w/v) DSS water for 5 days. Meanwhile, mice in the HQD-L, HQD-H and 5-ASA groups were administrated with 100, 200 mg/kg HQD or 100 mg/kg 5-ASA, respectively, once daily by gavage. After 9 days of administration, the body weight, disease activity index (DAI) score and colon length of mice were measured, the pathological changes of colons were analyzed by hematoxylin-eosin staining (HE) staining, and the levels of serum interleukin (IL)-6, IL-1β and TNF-α were measured by enzyme linked immunosorbent assay. In vitro, the human colon epithelial normal cells (FHC cells) were exposed to HQD (0.6 mg/mL) for 12 h and then treated with TNF-α (10 ng/mL) for 24 h. The tight junction (TJ) protein expression levels of Claudin-4 and Occludin, and the protein phosphorylation levels of p65 and inhibitor of nuclear factor kappaB (NF-κB)-α (IκBα) were measured by Western blot.@*RESULTS@#In vivo, compared with the DSS group, HQD-H treatment attenuated the weight loss and reduced DAI score of mice on the 8th day (P<0.05). Moreover, HQD-H treatment ameliorated the colon shortening in the DSS-induced colitis mice (P<0.05). HE staining showed HQD attenuated the pathological changes of colitis mice, and the histological scores of HQD-H and 5-ASA groups were significantly decreased compared with the DSS group (P<0.05). Meanwhile, HQD-H and 5-ASA significantly decreased the serum IL-1β, IL-6 and TNF-α levels of mice (P<0.05). In vitro experiments showed that HQD up-regulated Occludin and Claudin-4 protein expressions and inhibited p-p65 and p-IκBα levels in FHC cells compared with the TNF-α group (P<0.05).@*CONCLUSION@#HQD significantly relieved the symptoms in DSS-induced colitis mice by inhibiting pro-inflammatory cytokines expression and maintained the homeostasis of TJ protein in FHC cells by suppressing TNF-α-induced NF-κB activation.

An experimental study on brain protective effect of Sini decoction on post-resuscitation syndrome / 中国中西医结合急救杂志

Objective To approach the brain protective effect and mechanism of Sini decoction on rats with cardiopulmonary resuscitation (CPR) syndrome.Methods Fifty Sprague-Dawley (SD) rats were divided into sham operation group (n = 10), CPR model group (n = 20) and Sini decoction treatment group (n = 20) by random number table. The rat models were established by trachea clipping to induce cardiac arrest, and after heart beat stopped for 5 minutes, CPR was carried out. In the Sini decoction group, Sini decoction 5 g/kg was given through a stomach tube, once per 24 hours, while in the sham and CPR model groups, the same amount of normal saline was given by the same method at the same time. Venous blood was collected before CPR and 6, 12, 24, 48 and 72 hours after CPR, and the levels of serum interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) were determined by enzyme linked immunosorbent test (ELISA); after CPR for 72 hours, the rat brain tissue was obtained from all the groups, the content of caspase-3 in brain tissue was detected by immunohistochemistry method, and its protein expression caspase-3 was detected by Western Blot; the apoptosis situation of brain tissue was detected by terminal deoxynucleotidyl transferase-mediated duTP nick end labeling (TUNEL).Results With the prolongation of time, the levels of IL-6 and TNF-α in CPR model and Sini decoction groups showed a tendency firstly increased and then decreased, IL-6 reached its peak value after resuscitation for 24 hours, while TNF-α reached its peak value after resuscitation for 48 hours, and both IL-6 and TNF-α were decreased after resuscitation for 72 hours ; beginning from 6 hours after resuscitation, the levels of serum IL-6 (ng/L: 61.79±1.31, 62.49±1.42 vs. 21.48±0.79) and TNF-α (ng/L: 48.32±1.98, 25.32±1.96 vs. 18.34±2.45) in CPR model and Sini decoction treatment groups were all significantly higher than those in sham group, since 12 hours after resuscitation, the level of IL-6 was significantly lower in Sini decoction than that in CPR model group (ng/L: 70.41±2.21 vs. 88.32±1.59), and since 6 hours after resuscitation, TNF-α was obviously lower in Sini decoction group than that in CPR model group (ng/L: 25.32±1.96 vs. 48.32±1.98, allP < 0.05), both IL-6, TNF-α persisting to 72 hours after resuscitation, and their levels did not return to normal at the end of experiment in the two groups. After the end of resuscitation, the content and protein expression of caspase-3 and rate of cell apoptosis in the brain tissue in CPR model group were significantly higher than those in the sham group [caspase-3 content (A value,×103): 2.59±0.26 vs. 1.57±0.06, caspase-3 protein (gray value): 0.80±0.08 vs. 0.43±0.04, apoptosis rate: (2.01±0.08)% vs. (0.26±0.02)%, allP < 0.05], above indexes in the Sini decoction treatment group were significantly lower than those in the CPR model group [caspase-3 content (A value,×103): 1.89±0.08 vs. 2.59±0.26, caspase-3 protein (gray value): 0.57±0.02 vs. 0.80±0.08, apoptosis rate: (1.03±0.05)% vs. (2.01±0.08)%, allP < 0.05).Conclusion The Sini decoction has a protective effect on rats with post-resuscitation syndrome, and its mechanism is possibly realized by the inhibition of inflammatory factors and reduction of cell apoptosis.

Objective To investigate the clinical efficacy of edaravone combined with β-aescin sodium for treatment of elderly patients with acute cerebral hemorrhage,and the dynamic changes of tumor necrosis factor-α(TNF-α) and C-reactive protein (CRP),vascular endothelial growth factor (VEGF) levels in serum in such patients before and after treatment.Methods A total of 99 elderly patients with acute cerebral hemorrhage admitted to Henan Nanyang Second General Hospital from April 2014 to February 2016 were enrolled,and they were divided into control group (49 cases) and observation group (50 cases) according to the random digital table.Conventional treatment were given to both groups,patients in the observation group were added with edaravone 30 mg intravenous drip,2 times a day and β-aescin 20 mg intravenous drip,once daily.After treatment for consecutive 2 weeks,the clinical effect and neurological deficit score (NDS) were observed in the two groups;serum CRP levels were detected by immunonephelometry;TNF-αα and VEGF were detected by enzyme linked immunosorbent assay (ELISA).The changes of CRP,VEGF,TNF-α levels and incidence of adverse reactions before and after treatment were compared between the two groups.Results The levels of NDS,CRP,VEGF and TNF-α in both groups after treatment were significantly lower than those before treatment,and the degrees of decrease in treatment group were more significant than those in control group [NDS score:13.01 ± 1.37 vs.20.63 ± 1.68,CRP (mg/L):8.05 ± 3.97 vs.10.04 ± 4.17,VEGF (ng/L):97.25 ± 13.73 vs.116.43 ± 14.10,TNF-α (ng/L):8.15 ± 2.52 vs.11.54 ± 2.22,all P ＜ 0.05];the total effective rate in observation group was significantly higher than that in control group [92.00％ (46/50) vs.77.55％ (38/49),P ＜ 0.05].The difference of incidence of adverse reaction between observation group and control group was not statistically significant [4.00％ (2/50) vs.8.16％ (4/49),P ＞ 0.05].Conclusions Edaravone combined with β-aescin sodium for treatment of elderly patients with acute cerebral hemorrhage can effectively promote the recovery of neurological function,and its rolemight be related to the regulation of the levels of CRP,TNF-α and VEGF.

Effect of Electroacupuncture at Points Xiaohai and Xiajuxu on ChAT andα 7 nAchR in a Rat Model of DU / 上海针灸杂志

Objective To investigate the effect of electroacupuncture at points Xiaohai and Xiajuxu on the expressions of tumour necrosis factor-α (TNF-α) and choline acetyltransferase (ChAT) in serum and nicotinic acetylcholine receptorα 7 (α 7 nAchR) in duodenal tissues in a rat model of duodenal ulcer (DU) and preliminarily explore the relative specificity of He-Sea point in “treating visceral diseases with He-Sea point”.Methods Forty healthy SD rats were randomized into blank (A), model (B), Xiaohai (C) and Xiajuxu (D) groups, 10 rats each. A rat model of DU was made by subcutaneous injection of 10% cysteamine hydrochloride at the right buttock. After successful model making, group C was given electroacupuncture at point Xiaohai and group D, at point Xiajuxu. Duodenal tissue ulcer was macroscopically observed and scored in every group of rats. Rat serum expression of TNF-α was determined by double antibody sandwich enzyme-linked immunosorbent assay (ELISA); rat serum expression of ChAT, by ultraviolet spectrophotometry & colorimetry; rat duodenal expression ofα7 nAchR, by Western blot.Results After model making, the duodenal ulcer score was significantly higher in groups B, C and D than in group A (allP0.05) and was significantly higher in group D than in group B (P<0.01) or C (P<0.05).α7 nAchR expression was significantly higher in groups C and D than in group B (bothP<0.01). There was a positive correlation between ChAT andα7 nAchR expressions in every group (r=0.444,P=0.007).Conclusions Electroacupuncture at both points Xiaohai and Xiajuxu can reduce the duodenal ulcer score and serum TNF-α expression and increase serum ChAT and duodenalα7 nAchR expressions in DU rats. The results show that the therapeutic effect of electroacupuncture on duodenal ulcer may be produced by regulating TNF-α. Its mechanism may be activating cholinergic anti-inflammatory pathway to produce an anti-inflammatory effect. The effect being better in group D than in group C suggests that Xiajuxu has the relative specificity.
