Methods A total of 30 New Zealand male white rabbits were randomly divided into 5 groups. Group A: blank group;group B: model group;group C: Buddlejae Flos (Mi Meng Hua,密蒙花) granules group;group D: placebo group;group E: testosterone group. Except for the group A, all rabbits were treated with bilateral testicular and epididymis resection before intervention. Rabbits in group C were administered with Buddlejae Flos (Mi Meng Hua,密蒙花) granules (100 mg/kg), 3 times per day;Rabbits in group D were administered with normal saline, 3 times per day. Rabbits in group E were injected with testosterone propionate (0.5 mL/kg) in the thigh muscle, every 3 days. Schirmer I test (SIT) and break-up time (BUT) were measured on 1st day before modeling and 30th day after modeling. After 30 days of intervention, all rabbits were sacrificed. The removal lacrimal gland was stained in immunohistochemica staining. The expression of TGF-β1, NF-κB, IL-10 and IL-12 in lacrimal gland tissue of each group was detected, and the structure of lacrimal gland was observed. Results The results of SIT and BUT showed that there was significant difference between group B and D compared with group A (P < 0.05). There were no significant differences between group C and E (P > 0.05). There were no significant differences in the comparison of inflammatory factors TGF-β1, NF-κB, IL-10 and IL-12 between group B and D (P > 0.05). There were significant differences between group B and D compared with other groups (P < 0.01). There was no significant difference between group A, C and E (P > 0.05). Conclusions Buddlejae Flos (Mi Meng Hua,密蒙花) granules have an inhibitory effect on the expression of TGF-β1, NF-κB, IL-10 and IL-12 in castrated male rabbit lacrimal gland cells, and alleviate the inflammation of lacrimal gland tissue by inhibiting the expression of TGF-β1, NF-κB, IL-10 and IL-12 in lacrimal gland tissue, so as to treat dry eye.展开更多

The viability of human corneal epithelial cells(HCECs) was measured using a cell counting kit(CCK-8).Tear secretion was assessed using the phenol red cotton test. The tear break-up time(TBUT) was recorded using 0.1% liquid fluorescein sodium. Corneal epithelial permeability was evaluated through Oregon green dextran(OGD) staining.Conjunctival goblet cells were counted using periodic acid-Schiff(PAS) staining. Terminal deoxynucleotidyl transfer d UTP nickend labeling(TUNEL) staining was used to quantify apoptotic cells in both models. The expression of Ki-67 was measured in HCECs in the cell model while that of matrix metalloproteinase(MMP)-3 and-9 was measured in the murine model through immunofluorescence staining. Real-time quantitative PCR(RTqPCR) was performed to assess the expression of MMP-3 and MMP-9 in the corneal epithelium and NLRP3, ASC, Caspase-1,interleukin(IL)-1β, IL-18, and tumor necrosis factor(TNF)-α in the conjunctiva. The protein expression levels of NLRP3, ASC,Caspase-1, IL-1β, and IL-18 in the conjunctiva were assessed via Western blot.Results In the in vitro model, treatment of HCECs with LA showed no toxicity, increased proliferation, and reduced apoptosis. In the murine model, compared to the control, LA significantly increased tear production and TBUT, improved OGD staining, and increased the number of goblet cells. Topical treatment of LA to mice provided decreased expression of MMP-3, MMP-9, TNF-α, and apoptotic corneal epithelium.

文摘Objective To observe the effects of Buddlejae Flos (Mi Meng Hua,密蒙花) granules on the expression of TGF-β1, NF-κB, IL-10 and IL-12 in lacrimal gland cells in castrated male rabbits. Methods A total of 30 New Zealand male white rabbits were randomly divided into 5 groups. Group A: blank group;group B: model group;group C: Buddlejae Flos (Mi Meng Hua,密蒙花) granules group;group D: placebo group;group E: testosterone group. Except for the group A, all rabbits were treated with bilateral testicular and epididymis resection before intervention. Rabbits in group C were administered with Buddlejae Flos (Mi Meng Hua,密蒙花) granules (100 mg/kg), 3 times per day;Rabbits in group D were administered with normal saline, 3 times per day. Rabbits in group E were injected with testosterone propionate (0.5 mL/kg) in the thigh muscle, every 3 days. Schirmer I test (SIT) and break-up time (BUT) were measured on 1st day before modeling and 30th day after modeling. After 30 days of intervention, all rabbits were sacrificed. The removal lacrimal gland was stained in immunohistochemica staining. The expression of TGF-β1, NF-κB, IL-10 and IL-12 in lacrimal gland tissue of each group was detected, and the structure of lacrimal gland was observed. Results The results of SIT and BUT showed that there was significant difference between group B and D compared with group A (P < 0.05). There were no significant differences between group C and E (P > 0.05). There were no significant differences in the comparison of inflammatory factors TGF-β1, NF-κB, IL-10 and IL-12 between group B and D (P > 0.05). There were significant differences between group B and D compared with other groups (P < 0.01). There was no significant difference between group A, C and E (P > 0.05). Conclusions Buddlejae Flos (Mi Meng Hua,密蒙花) granules have an inhibitory effect on the expression of TGF-β1, NF-κB, IL-10 and IL-12 in castrated male rabbit lacrimal gland cells, and alleviate the inflammation of lacrimal gland tissue by inhibiting the expression of TGF-β1, NF-κB, IL-10 and IL-12 in lacrimal gland tissue, so as to treat dry eye.

文摘Objective Despite the potential therapeutic approaches of bone marrow-derived mesenchymal stem cells(BMSCs)in orthopaedic,their applications are hampered by harsh oxidative stress conditions after transplantation.In this study,the antiapoptotic and anti-oxidative properties of lithospermic acid(LSA)on BMSCs exposed to hydrogen peroxide(H2O2)were investigated.Methods In the present study,we used H2O2 to induce oxidative injury on BMSCs.Reactive oxygen species(ROS)staining and superoxide dismutase(SOD)assay were performed.The expression levels of phosphorylated(p)-Akt,Bcl-2-associated X protein(Bax)and B-cell lymphoma 2(Bcl-2)were measured by Western blotting.Results LSA can significantly reduce H2O2-induced chromatin condensation and intracellular ROS levels,enhance the activity of SOD.Moreover,it can alleviate H2O2-induced apoptosis by upregulating Bcl-2 and p-Akt,down-regulating Bax,which was blocked by the PI3K inhibitor,LY294002.Conclusions Our results demonstrated that pretreatment with LSA could attenuate oxidative stress-induced apoptosis in BMSCs,which may be related with anti-oxidant properties and partly via modulating PI3K/Akt pathway,suggesting that pharmacologically manipulating BMSCs with LSA could be a promising drug to increase cell survival for BMSCs transplantation in musculoskeletal disorders of orthopaedic.

文摘Objective To observe the effects of Centipede Scolopendra extraction(CSE)on human liver cancer HepG2 cells and the nude mouse tumor model of liver orthotopic transplantation,and to explore the anti-liver cancer mechanism of the extract.Methods HepG2 cells were respectively treated with CSE250(250μg/mL),CSE500(500μg/mL)and 5-FU,and control group was established.An enzymatic hydrolysis and acetone precipitation method was used to separate and purify CSE,which was then used to treat HepG2 cells.The CCK8 assay was used to detect the inhibition of cell proliferation and the half maximal inhibitory concentration(IC50)was calculated.Flow cytometry was used to analyze the cell cycle,and western blot was used to detect the expression of signal transduction and activator of transcription 3(STAT3)pathway-related proteins in HepG2 cells treated with CSE.A nude mouse model with an orthotopic liver tumor was prepared.The mice were randomly divided into four groups,each containing 12 animals:the model group,the 5-FU group,the CSE10 group[10 mg/(kg·d)]and the CSE50 group[50 mg/(kg·d)].The volume and mass changes in the nude mice with orthotopic transplanted tumors were observed.Western blot method was used to test the protein expression levels of p-STAT3 and p38 mitogen-activated protein kinase(p38MAPK).Tissues from the liver of mice in the model group and the CSE50 group were analyzed by using a protein tyrosine kinase(PTK)chip,and the Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)function enrichment analysis of the differentially expressed proteins was performed.Results This study showed that CSE significantly inhibited the proliferation of HepG2 cells(P<0.05).After 48 h of CSE treatment,the cell cycle of HepG2 cells manifested as S phase and G2/M phase;p-STAT3 protein levels in the CSE groups were significantly lower than that in the control group(P<0.05).Analysis of the tumor inhibition in the mice showed that the tumor masses and volume in CSE groups were lower(P<0.05).The protein levels of p-STAT3 and p38MAPK in CSE50 group and 5-FU group decreased significantly(P<0.05).PTK antibody chip screening results showed that CSE groups had a bidirectional regulation trend,and there were 23 up-regulated PTKs and six down-regulated PTKs.The GO and KEGG analyses showed that CSE exerted its anticancer effects through regulation of biological processes,including mitogen-activated protein kinase(MAPK)cascade,chemotaxis,cell invasion,cell adhesion,angiogenesis and other biological processes,and through signaling pathways,including the MAPK,phosphatidylinositol-3-kinase/serine threonine protein kinase(PI3K/AKT),and RAS signaling pathways.Conclusions CSE can effectively inhibite the proliferation of HepG2 cells and effectively inhibite the growth of liver cancer orthotopic transplantation tumor.Its mechanism may be closely related to the regulation of STAT3,MAPK and PI3K/AKT signaling pathways.

文摘Objective To investigate the effectiveness of compound Chai Jin Jie Yu Tablets(CJJYT)in ameliorating cognitive impairment associated with depression and its potential mechanism of action.Methods In vitro experiments,the hippocampus was isolated from the whole brain of the fetal rat and cultured into hippocampal neuron cells.50μM corticosterone(CORT)was added to each group 18 h before the experiment for modeling depression,with the exception of the control group.After modeling,the blank serum group was added with 10%blank serum,the CJJYT group and the venlafaxine group were added with the corresponding 10%drug-containing serum,and the control group and the model group were added with equal volumes of culture medium.The intracellular Ca^2+mean fluorescence intensity,miniature excitatory postsynaptic current(mEPSC)current amplitude,and frequency of different hippocampal neurons were evaluated as indicators of synaptic function in the hippocampal neurons.In addition,the expression of synaptic plasticity related proteins,synaptophysin-α(SYN-α),N-methyl-D-aspartate receptor 2A(NR2A),N-methyl-Daspartate receptor 2B(NR2B),post synaptic density 95 protein(PSD-95),calcium/calmodulin dependent protein kinaseⅡ(CaMKⅡ)and synaptic associated protein(SynGAP)were detected in the hippocampal neurons by immunofluorescence staining and high content analysis(HCA)system.Then,reverse transcription-polymerase chain reaction(RT-PCR)was used to detect the mRNA expression levels of SYN-α,NR2A,NR2B,PSD-95,CaMKⅡand SynGAP.For in vivo experiments,except for those in the blank control group,all rats were treated within a single cage for chronic unpredictable stress-induced depression modeling and subjected to corresponding drug interventions.Behavioral tests were used to detect depressive behavior and determine learning,memory and other cognitive abilities,whereas enzyme-linked immunosorbent assay(ELISA)was used to detect the CORT levels.Golgi-Cox staining was used to observe changes in the synaptic morphology of parahippocampal gyrus CA1 area(CA1)and dentategyrus(DG).Results In vitro,CJJYT treatment reduced the intracellular Ca^2+mean flurorescence intensity in the hippocampal neurons(P<0.05),causing a reduction in the frequency and current amplitude of mEPSC(P<0.05),and thus inhibited the excessive activation of post-synaptic receptors.CJJYT treatment reduced the protein and mRNA expression of SYN-α,NR2A,NR2B and PSD-95 in the hippocampal neurons(P<0.05),increased the mRNA and protein expression of CaMKⅡand SynGAP(P<0.05),and thereby improved the synaptic plasticity of the hippocampal neurons.In vivo,CJJYT intervention improved sucrose preference,voluntary activity,learning and memory ability of Morris water maze test,and suppressed appetite(P<0.05),and increased the despair feeling of forced swimming test(P<0.05).The CORT level was reduced(P<0.05),leading to the repair of synaptic damage in the hippocampal neurons.Conclusions CJJYT can improve the synaptic function of hippocampal neurons and has obvious protective effects on neurons.It can repair the structural damage in the hippocampal neurons,improving the cognitive ability of the depressed model rats.The mechanism of CJJYT improving cognition in depressed rats may be related to the transmission and function of SYN-α/NR and its downstream neurotransmitters.

文摘Objective To investigate the effect and mechanism of linarin(LA) in an experimental dry eye model.Methods LA or vehicle was applied in two dry eye models: an in vitro hyperosmotic stress model and an in vivo desiccating stress(DS) murine model. The viability of human corneal epithelial cells(HCECs) was measured using a cell counting kit(CCK-8).Tear secretion was assessed using the phenol red cotton test. The tear break-up time(TBUT) was recorded using 0.1% liquid fluorescein sodium. Corneal epithelial permeability was evaluated through Oregon green dextran(OGD) staining.Conjunctival goblet cells were counted using periodic acid-Schiff(PAS) staining. Terminal deoxynucleotidyl transfer d UTP nickend labeling(TUNEL) staining was used to quantify apoptotic cells in both models. The expression of Ki-67 was measured in HCECs in the cell model while that of matrix metalloproteinase(MMP)-3 and-9 was measured in the murine model through immunofluorescence staining. Real-time quantitative PCR(RTqPCR) was performed to assess the expression of MMP-3 and MMP-9 in the corneal epithelium and NLRP3, ASC, Caspase-1,interleukin(IL)-1β, IL-18, and tumor necrosis factor(TNF)-α in the conjunctiva. The protein expression levels of NLRP3, ASC,Caspase-1, IL-1β, and IL-18 in the conjunctiva were assessed via Western blot.Results In the in vitro model, treatment of HCECs with LA showed no toxicity, increased proliferation, and reduced apoptosis. In the murine model, compared to the control, LA significantly increased tear production and TBUT, improved OGD staining, and increased the number of goblet cells. Topical treatment of LA to mice provided decreased expression of MMP-3, MMP-9, TNF-α, and apoptotic corneal epithelium. Topical administration of LA also suppressed the NLRP3 inflammasome in the dry eye disease(DED) murine model by decreasing the expression of NLRP3, ASC, Caspase-1, IL-1β, and IL-18 in the conjunctiva.Conclusion Our findings support the safety and efficacy of LA in the treatment of DED. LA alleviated corneal epithelial damage and suppressed NLRP3 inflammasome-mediated immunity in the conjunctiva in a murine model of DED.

文摘Objective To observe the effects of total flavonoids of chrysanthemum and medicated serum on the expression of related proteins in the lacrimal tissue and dry-eye cell models of male rabbits with dry eye caused by castration.Methods(1)150 male Japanese rabbits were randomly divided into five groups,with 30 rabbits in each group:normal control group(group A),sham group(group B),model group(group C),androgen control group(group D)and total flavonoids of chrysanthemum treatment group(group E).The androgen deficiency dry-eye model was established by bilateral castration in groups C,D and E.Normal saline was administered to groups A,B and C by gavage;androgen(testosterone propionate)was injected into muscle in group D;and group E was given total flavonoids of chrysanthemum by gavage.All white rabbits were tested the Schirmer I test(SIT)and tear break-up time(BUT).After euthanasia,tear gland tissue was harvested so that we could observe pathological changes in the expression of related inflammatory factors in the lacrimal gland tissue.The expression of interleukin-1β(IL-1β),tumor necrosis factor-α(TNF-α)and transforming growth factor-β1(TGF-β1)was detected in the lacrimal gland tissue by immunohistochemistry.Reverse transcription PCR was used to quantitatively detect expression of TGF-β1 mRNA.(2)Male Wistar rat lacrimal epithelial cells were used to establish a model of eye stem cell apoptosis caused by androgen levels.The blank control group was set up without androgen culture,the control group with androgen culture,and the total flavonoids of chrysanthemum group without androgen.The MTT method was used to determine the optimal intervention dosage of drug-containing plasma.Western blot and QPCR were used to detect the expression of AR mRNA,NF-κB phosphorylated protein and TGF-β1 in lacrimal epithelial cells,and the androgen-like effect of total flavonoids of chrysanthemum was observed.Results(1)Immunohistochemistry showed that groups A,B,D and E had significantly lower expression of IL-1βand TNF-αthan group C(P<0.05);among these,group E had slightly higher expression than group D(P>0.05).RT-PCR results showed that the relative expression of TGF-β1 mRNA in groups A,B,D and E was significantly higher than in group C(P<0.05),and the relative expression of TGF-β1 mRNA in groups D and E was higher than that in groups A and B(P<0.05).(2)Using the MTT method,the final concentration of interfering cells was calculated to be 13.2%.The expression of AR protein,NF-κB and TGF-β1 in the chrysanthemum flavonoid plasma intervention and testosterone propionate intervention groups was enhanced,and there were significant differences relative to the blank group(P<0.01).The expression level of NF-κB in the total flavonoid containing plasma intervention group was lower than that in the testosterone propionate intervention group(P<0.01).Conclusions The total flavonoids of chrysanthemum can inhibit IL-1βand TNF-αexpression in the lacrimal gland tissue of castrated male rabbits with dry eye to increase synthesis of TGF-β1 mRNA and TGF-β1,thereby inhibiting the inflammatory response.The medicated plasma with total flavonoids of chrysanthemum promotes expression of AR mRNA,upregulating expression of NF-κB,further promoting upregulation of TGF-β1 protein expression in lacrimal epithelial cells,inhibiting inflammation by regulating related proteins,and ultimately alleviating the symptoms of dry eye.

文摘The meibomian gland is a unique sebaceous gland located in the eyelid.Its main function is to secrete lipids and form the lipid layer of the tear film to delay the evaporation of waterborne tears,increase the surface tension of the tear film,and to lubricate the contact area of the eyelid and eyeball.Abnormal secretion of the meibomian gland is known as meibomian gland dysfunction(MGD),which has become the most important cause of evaporative dry eye disease(DED).The clinical pathophysiological process and underlying molecular mechanisms of MGD are not clear.As serious side effects may occur with the long-term use of hormonotherapy and non-steroidal anti-inflammatory drugs(NSAIDs)for the treatment of MGD,meibomian gland physiotherapy is considered the most effective and safest therapy for MGD.This review summarizes the physical therapy modalities of western medicine(WM)and traditiond Chinese medicine(TCM)for the treatment of MGD to provide optimal treatments for these patients and to further lay a foundation for mechanistic studies of MGD.
