ABSTRACT
ABSTRACT Objective: This study aimed to compare the levels of HIF1-α, VEGF, TNF-α, and IL-10 in the peri-implant crevicular fluid of patients with and without peri-implantitis. Methods: Forty patients, comprising 16 with and 24 without peri-implantitis were selected. Results: Patients with peri-implantitis exhibited significantly higher HIF-1α levels than those without peri-implantitis (p=0.0005). TNF-α revealed significant positive correlations with IL-10 (p=0.0008) and VEGF (p=0.0246), whereas HIF-1α and IL-10 levels (p=0.0041) demonstrated a negative and significative correlation in the peri-implantitis group. Conclusion: This study, for the first time demonstrates the balance of HIF-1α, TNFα, IL-10, and VEGF in peri-implantitis. It shows an elevated HIF-1α levels in patients with peri-implantitis, which could have stemmed from persistent inflammation- triggered hypoxia. Furthermore, the positive correlation between TNF-α and VEGF suggests intensified proinflammatory activity in peri-implantitis. Nevertheless, further studies are essential to understand these immune dynamics in peri-implantitis.
ABSTRACT
Background: Interleukin?10 (IL?10) and tumor necrosis factor?alpha (TNF??) genes contribute to oncogenesis. We evaluated the influence of the IL?10 (G1082A) and TNF?? (G308A) polymorphisms on the prognosis and outcomes of Egyptian patients with acute lymphoblastic leukemia (ALL). Materials and Methods: We investigated 64 children and 76 adults with ALL, between 2016 and 2019, for the IL?10 (G1082A) and TNF?? (G308A) polymorphisms using allele?specific polymerase chain reaction and polymerase chain reaction杛estriction fragment length polymorphism. Survival analyses were performed using the Kaplan朚eier estimator and the log?rank test. Results: In children with ALL, the A allele of TNF?? and IL?10 polymorphisms was associated with older age (P = 0.04 and 0.03), more extramedullary disease (P = 0.02 and 0.001), positive breakpoint cluster region朅belson (BCR?ABL) rearrangement (p190; P = 0.04 and 0.001), and more relapse (P = 0.002). The IL?10 GG genotype was associated with higher overall survival in children (P = 0.026). Adults carrying the TNF?? A allele showed more extramedullary disease (P = 0.009) and relapse (P = 0.003). We also found a higher frequency of IL?10 A allele in adults with older age (P = 0.03), lower hemoglobin level (P = 0.04), positive BCR?ABL rearrangement (P = 0.001), more extramedullary disease (P = 0.001), more relapse (P = 0.002), and a longer time for the first complete remission (P = 0.003). Conclusion: A possible association exists between the A allele of IL?10 and TNF?? polymorphisms and poor prognosis in Egyptian patients with ALL, while the IL?10 GG genotype may be associated with better survival in children with ALL.
ABSTRACT
ABSTRACT Objective: To determine whether polymorphisms of the IL10 and IL17 genes are associated with severe asthma control and bronchodilator reversibility in children and adolescents with severe asthma. Methods: This was a cross-sectional study, nested within a prospective cohort study of patients with severe asthma. Two outcomes were evaluated: asthma control and bronchodilator reversibility. We extracted DNA from peripheral blood and genotyped three single nucleotide polymorphisms: rs3819024 and rs2275913 in the IL17A gene; and rs3024498 in the IL10 gene. For the association analyses, we performed logistic regression in three genetic models (allelic, additive, and dominant). Results: The rs3024498 C allele in the IL10 gene was associated with failure to achieve asthma control despite regular treatment (p = 0.02). However, the G allele of the IL17A rs3819024 polymorphism was associated with failure to respond to stimulation with a b2 agonist. The rs2275913 polymorphism of the IL17A gene showed no relationship with asthma control or bronchodilator reversibility. Conclusions: In pediatric patients with severe asthma, the IL10 polymorphism appears to be associated with failure to achieve clinical control, whereas the IL17A polymorphism appears to be associated with a worse bronchodilator response. Knowledge of the involvement of these polymorphisms opens future directions for pharmacogenetic studies and for the implementation of individualized therapeutic management of severe asthma in pediatric patients.
RESUMO Objetivo: Determinar se existe relação entre polimorfismos dos genes IL10 e IL17 e controle da asma grave e reversibilidade com broncodilatador em crianças e adolescentes com asma grave. Métodos: Estudo transversal, aninhado em um estudo prospectivo de coorte com pacientes com asma grave. Foram avaliados dois desfechos: controle da asma e reversibilidade com broncodilatador. Extraímos DNA do sangue periférico e genotipamos três polimorfismos de nucleotídeo único: rs3819024 e rs2275913 no gene IL17A e rs3024498 no gene IL10. Para as análises de associação, realizamos regressão logística em três modelos genéticos (alélico, aditivo e dominante). Resultados: O alelo C do polimorfismo rs3024498 do gene IL10 apresentou relação com asma que permaneceu descontrolada mesmo com tratamento regular (p = 0,02). No entanto, o alelo G do polimorfismo rs3819024 do gene IL17A apresentou relação com ausência de resposta ao estímulo com b2-agonista. O polimorfismo rs2275913 do gene IL17A não apresentou relação com controle da asma ou reversibilidade com broncodilatador. Conclusões: Em pacientes pediátricos com asma grave, o polimorfismo do gene IL10 parece estar relacionado com ausência de controle clínico, ao passo que o polimorfismo do gene IL17A parece estar relacionado com pior resposta ao broncodilatador. O conhecimento a respeito do envolvimento desses polimorfismos abre perspectivas futuras para estudos farmacogenéticos e para a implantação de manejo terapêutico individualizado da asma grave em pacientes pediátricos.
ABSTRACT
Objective:To study the relationship between the level of serum homocysteine (Hcy) and the antisense non coding gene (ANRIL) of long chain non coding RNA (lncRNA) cell cycle dependent kinase inhibitor 2B gene, and the effect on Atherosclerosis inflammation, that is, the expression of interleukin-10 (IL-10) and Monocyte chemoattractant protein-1 (MCP-1) in Human umbilical vein endothelial cell (HUVEC).Methods:HUVEC was cultured in vitro and cells were treated with different concentration gradients (blank control group, 0.5, 1.0, 2.0, 5.0 mmol/L) of Hcy. The expression level of lncRNA ANRIL was detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR). Enzyme linked immunosorbent assay (ELISA) was used to detect the levels of MCP-1 and IL-10. LipoFilter transfection reagents were used to transfect shANRIL and shNC into different cells, respectively. In the above experiment, the optimal Hcy concentration (5.0 mmol/L) was selected for intervention for 24 hours. Western blot was used to detect the protein expression levels of MCP-1 and IL-10.Results:After 24 hours of intervention with different concentrations of Hcy in HUVEC, Hcy significantly damaged endothelial cells, and the higher the Hcy concentration, the more severe the cell damage. Compared with the blank control group, the Hcy intervention group showed an increase in lncRNA ANRIL and MCP-1, while IL-10 decreased (all P<0.05); As the concentration of Hcy intervention increases, IL-10 decreases, while lncRNA ANRIL and MCP-1 increased (all P<0.05). Compared with the blank control group, the Hcy group, the shNC+ Hcy group, and the shANRIL+ Hcy group had lower levels of IL-10 protein expression and higher levels of MCP-1 protein expression (all P<0.05). Compared with the shANRIL+ Hcy group, the Hcy group and the shNC+ Hcy group had lower levels of IL-10 protein expression and higher levels of MCP-1 protein expression (all P<0.05). There was no statistically significant difference in the expression levels of IL-10 protein and MCP-1 protein between the shNC+ Hcy group and the Hcy group (all P>0.05). Conclusions:Hcy upregulates MCP-1 expression and downregulates IL-10 expression by promoting lncRNA ANRIL expression. Thus, it can promote cellular inflammatory reaction and participate in Atherosclerosis.
ABSTRACT
Objective:To investigate the effects of thoracic segment epidural anesthesia on inflammatory factors in patients undergoing lung cancer surgery.Methods:The clinical data of 136 patients who underwent lung cancer surgery in the Second People's Hospital of Liaocheng from June 2020 to May 2022 were retrospectively analyzed. According to anesthesia methods, these patients were divided into an observation group ( n = 89) and a control group ( n = 47). The observation group was given thoracic segment epidural anesthesia, while the control group was given remifentanil infusion anesthesia. The tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-10 (IL-10) levels in the epithelial lining fluid collected from the non-dependent lung, the plasma levels of TNF-α, IL-6, and malondialdehyde, arterial partial pressure of oxygen/inhaled oxygen fraction, the incidence of complications, the incidence of re-operations, numeric rating scale score, and the length of hospital stay were compared between the two groups. The effects of different anesthesia methods on lung cancer surgery were evaluated. Results:In each group, TNF-α, IL-6, and IL-10 levels in the epithelial lining fluid were significantly increased 30 minutes after termination of one-lung ventilation (T2) compared with those measured before one-lung ventilation (T1) ( t = 7.71, 77.10, 7.59, 3.41, 57.51, 5.74, all P < 0.05). In the observation group, TNF- α [(1.59 ± 0.53) ng/L, (1.89 ± 0.64) ng/L] measured at T1 and T2, IL-6 [(2.96 ± 0.82) ng/L] and IL-10 [(1.99 ± 0.53) ng/L] measured at T1 were significantly higher compared with those measured at the corresponding time points in the control group ( t = 10.45, 2.59, 2.00, 7.19, all P < 0.05). In the observation group, IL-6 measured at T2 [(38.91 ± 5.84) ng/L] was significantly lower than that in the control group ( t = 33.25, P < 0.001), and IL-10 measured at T2 [(2.51 ± 0.67) ng/L] was slightly, but not significantly higher than that in the control group ( P > 0.05). There was no significant difference in the plasma level of TNF- α measured at T1 and T2 between the two groups (both P > 0.05). Plasma levels of IL-6 in the two groups [(42.98 ± 5.29) ng/L, (27.93 ± 4.17) ng/L] measured at T2 were significantly increased compared with those measured at T1 ( t = 54.14, 61.06, both P < 0.001). In the observation group, TNF-α measured at T2 [(1.60 ± 0.56) ng/L] and IL-6 measured at T1 and T2 [(0.92 ± 0.16) ng/L, (27.93 ± 4.17) ng/L] were significantly lower compared with the control group ( t = 3.39, 6.96, 18.20, all P < 0.05). There were no significant differences in plasma level of malondialdehyde, arterial partial pressure of oxygen/inhaled oxygen fraction, numeric rating scale score, the incidence of complications, the incidence of re-operation, and the length of hospital stay between the two groups (all P > 0.05). Conclusion:Thoracic segment epidural anesthesia can reduce the local inflammatory response of the lung during lung cancer surgery.
ABSTRACT
Objective:To investigate the relationship between serum interleukin-6 and interleukin-10 levels and clinical prognosis in patients with severe acute pancreatitis.Methods:Ninety-two patients with severe acute pancreatitis who received treatment in The Second People's Hospital of Liaocheng from August 2018 to July 2021 were included in this study. Serum interleukin (IL)-6 and IL-10 levels were detected. The Bedside Index of Severity in Acute Pancreatitis (BISAP) score was evaluated. Clinical interventions were performed. The relationship between serum IL-6 and IL-10 levels and the clinical prognosis of severe acute pancreatitis was investigated.Results:Serum IL-6 level [(103.75 ± 15.53) ng/L] was highest in patients who died. Serum IL-10 level [(97.33 ± 13.06) ng/L] was highest in patients with local complications. The highest number of patients with a prognostic outcome of death [26 (37.14%)] was found in patients with a BISAP score ≥ 3. Serum IL-6 level in patients with severe acute pancreatitis was positively correlated with the BISAP score ( r = 0.62, P < 0.05), and serum IL-6 level and BISAP score were negatively correlated with serum IL-10 level ( r = -0.57, -0.61, both P < 0.05). Conclusion:Increased or decreased serum IL-6 and IL-10 levels in patients with severe acute pancreatitis indicate that the patient's condition tends to worsen, and timely intervention according to serum IL-6 and IL-10 levels can improve the clinical prognosis of severe acute pancreatitis.
ABSTRACT
Objective:To investigate the efficacy of Yupingfeng granule combined with cetirizine in the treatment of allergic rhinitis and its effects on serum inflammatory factor level. Methods:A total of 162 patients with allergic rhinitis admitted to Zhejiang Provincial Hospital of Chinese Medicine from January 2021 to March 2022 were included in this prospective controlled study. They were randomly divided into a control group and an observation group ( n = 81/group). The control group was treated with cetirizine and the observation group was treated with Yupingfeng granule combined with cetirizine. All patients were treated for 4 weeks. Clinical efficacy was compared between the two groups after 4 weeks of treatment. Main symptom score, nasal function indexes (total nasal airway resistance, nasal minimal cross-sectional area, and 0-5 cm nasal cavity volume), levels of inflammatory factors (interleukin-4, interleukin-6, and interleukin-10), and Rhinoconjunctivitis Quality of Life Questionnaire scores were compared between the two groups before and after 4 weeks of treatment. Results:Total response rate in the observation group was significantly higher than that in the control group [92.59% (75/81) vs. 79.01% (64/81), χ2 = 6.13, P < 0.05]. After 4 weeks of treatment, the scores of nasal congestion, nasal itching, and sneezing in the observation group were (0.63 ± 0.20) points, (0.70 ± 0.21) points, and (0.54 ± 0.17) points, which were significantly lower than (1.07 ± 0.23) points, (1.08 ± 0.24) points, and (0.89 ± 0.22) points in the control group ( t = 12.99, 10.72, 11.33, all P < 0.05). After 4 weeks of treatment, total nasal airway resistance in the observation group was significantly lower than that in the control group [(0.17 ± 0.05) kPa·s -1·L -1vs. (0.26 ± 0.06) kPa·s -1·L -1, t = 10.37, P < 0.05]. Nasal minimal cross-sectional area and 0-5 cm nasal cavity volume in the observation group were (0.94 ± 0.17) cm 2 and (9.74 ± 0.89) cm 3, respectively, which were significantly higher than (0.76 ± 0.10) cm 2 and (8.43 ± 0.78) cm 3 in the control group ( t = 8.21, 9.96, both P < 0.05). After 4 weeks of treatment, serum levels of interleukin-4 and interleukin-6 in the observation group were (67.79 ± 9.94) ng/L and (6.74 ± 1.42) ng/L, respectively, which were significantly lower than (104.31 ± 14.45) ng/L and (10.29 ± 2.56) ng/L in the control group ( t = 18.74, 10.91, both P < 0.05). Serum level of interleukin-10 in the observation group was significantly higher than that in the control group [(17.97 ± 2.54) ng/L vs. (12.48 ± 2.46) ng/L, t = 13.97, P < 0.05]. After 4 weeks of treatment, Rhinoconjunctivitis Quality of Life Questionnaire score in the observation group was significantly lower than that in the control group [(27.43 ± 8.82) points vs. (38.95 ± 7.76) points, t = 8.82, P < 0.05). Conclusion:Yupingfeng granule combined with cetirizine is highly effective on allergic rhinitis. The combined therapy can reduce clinical symptoms and inflammatory reactions, improve nasal function, and thereby improve quality of life.

The rates of excellent and good treatment, operation conditions, serum inflammatory stress response indexes levels before and 1 d and 1 week after surgery were compared, and recovery at 3 and 6 months after surgery, the incidence of complications and the degree of treatment satisfaction were counted.Results:The rates of excellent and good treatmentin the absorbable group were higher than that in the micro plate group: 95.92%(47/49) vs. 81.63%(40/49), χ2 = 5.02, P<0.05. The duration of operation in the absorbable group was longer than that in the microplate group: (43.28 ± 12.18) min vs. (31.29 ± 11.69) min; and the duration of hospital stay, fracture healing time and recovery time were shorter than those in the microplate group: (4.09 ± 1.18) d vs. (6.89 ± 2.12) d, (4.35 ± 1.05) weeks vs. (5.69 ± 1.38) weeks, (4.89 ± 1.10) d vs. (6.20 ± 2.01) d; the differences were statistically significant ( P<0.05). The levels of serum hs-CRP, IL-10 and ACTH in absorbable group were lower than those in microplate group at 1 d and 1 week after surgery ( P<0.05). At 3 and 6 months after surgery, the range of motion of metacarpophalangeal joint in the absorbable group was greater than that in the microplate group, and the loss of grip strength of the healthy side was less than that in the microplate group ( P<0.05). The incidence of complications in absorbable group was lower than that in microplate group: 6.12%(3/49) vs. 20.41%(10/49), χ2 = 4.35, P<0.05. Conclusions:The absorbable material internal fixation can achieve good results in the treatment of phalanx fracture, the postoperative recovery is fast, the incidence of complications is lower.
ABSTRACT
ObjectiveTo investigate the effect of Qiling Baitouweng Tang （QLBTWT） on proliferation and apoptosis， Janus kinase 2 （JAK2）/signal transducer and activator of transcription 3 （STAT3） signaling pathway and interleukin-10 （IL-10） in diffuse large B-cell lymphoma （DLBCL）. MethodWith human DLBCL cells OCI-LY10 and U2932 as research objects， cell proliferation was detected by cell counting kit-8 （CCK-8） assay. After treatment with 0， 4.6， 9.3， 18.7， 37.5， 75， 150 mg·L-1 QLBTWT for 24 h， the half-inhibitory concentration （IC50） of OCL-LY10 and U2932 cells was calculated to be 9.33， 16.13 mg·L-1， respectively， based on which， 9.5， 19， 38 mg·L-1 QLBTWT were selected for subsequent experiments. After 0， 9.5， 19， 38 mg·L-1 QLBTWT treatment for 24 h， the zymogen activities of Caspase-3， Caspase-8 and Caspase-9 in OCI-LY10 and U2932 cells were detected using corresponding activity assay kits （colorimetric）， and the IL-10 expression was detected by enzyme-linked immuno sorbent assay （ELISA）. The apoptosis rate and cell cycle of OCI-LY10 and U2932 cells treated with different concentrations of QLBTWT for 24 h were detected by flow cytometry. The expressions of apoptosis-related proteins ［B-cell lymphoma 2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cleaved poly adenosine diphosphate ribose polymerase （cleaved PARP）， cleaved Caspase-3］， JAK2， STAT3， phospho-JAK2 （p-JAK2）， phospho-STAT3 （p-STAT3） pathway proteins， and c-Myc protein in OCL-LY10 and U2932 cells after 24 h treatment with 0， 9.5， 19， 38 mg·L-1 QLBTWT were all tested by Western blot. ResultAfter QLBTWT treatment on OCI-LY10 and U2932 cells for 24 h， cell proliferation was inhibited in each QLBTWT group compared with that in the control group （P<0.05， P<0.01）. The zymogens of Caspase-3， Caspase-8 and Caspase-9 were activated （P<0.01）， and there was an increase in cell apoptosis （P<0.05， P<0.01） and cell cycle arrest at Gap phase1 （G1） phase in 9.5， 19 and 38 mg·L-1 QLBTWT group （P<0.05， P<0.01）. After 9.5， 19 and 38 mg·L-1 QLBTWT treatment on OCI-LY10 and U2932 cells for 24 h， the expressions of Bcl-2， p-JAK2 and p-STAT3 proteins were decreased （P<0.01）， and the expressions of Bax， cleaved PARP and cleaved Caspase-3 proteins were increased （P<0.01）， but no significant change was observed in the expressions of JAK2 and STAT3 proteins. Compared with the conditions in the control group， the expressions of c-Myc， p-JAK2， and p-STAT3 proteins were down-regulated in 19 mg·L-1 QLBTWT group and 19 mg·L-1 QLBTWT+10 μg·L-1 IL-10 group （P<0.05， P<0.01）， and up-regulated in 10 μg·L-1 IL-10 group （P<0.05， P<0.01）， while there was no difference in JAK2/STAT3 proteins. ConclusionQLBTWT can inhibit proliferation and induce apoptosis of human DLBCL cells OCI-LY10 and U2932， and the potential mechanism may be related to the regulation of JAK2/STAT3 signaling pathway.
ABSTRACT
Sepsis-induced liver injury (SILI) is an important cause of septicemia deaths. BaWeiBaiDuSan (BWBDS) was extracted from a formula of Panax ginseng C. A. Meyer, Lilium brownie F. E. Brown ex Miellez var. viridulum Baker, Polygonatum sibiricum Delar. ex Redoute, Lonicera japonica Thunb., Hippophae rhamnoides Linn., Amygdalus Communis Vas, Platycodon grandiflorus (Jacq.) A. DC., and Cortex Phelloderdri. Herein, we investigated whether the BWBDS treatment could reverse SILI by the mechanism of modulating gut microbiota. BWBDS protected mice against SILI, which was associated with promoting macrophage anti-inflammatory activity and enhancing intestinal integrity. BWBDS selectively promoted the growth of Lactobacillus johnsonii (L. johnsonii) in cecal ligation and puncture treated mice. Fecal microbiota transplantation treatment indicated that gut bacteria correlated with sepsis and was required for BWBDS anti-sepsis effects. Notably, L. johnsonii significantly reduced SILI by promoting macrophage anti-inflammatory activity, increasing interleukin-10+ M2 macrophage production and enhancing intestinal integrity. Furthermore, heat inactivation L. johnsonii (HI-L. johnsonii) treatment promoted macrophage anti-inflammatory activity and alleviated SILI. Our findings revealed BWBDS and gut microbiota L. johnsonii as novel prebiotic and probiotic that may be used to treat SILI. The potential underlying mechanism was at least in part, via L. johnsonii-dependent immune regulation and interleukin-10+ M2 macrophage production.
ABSTRACT
Leprosy continues to be an important health issue in several endemic countries. The global incidence of this disease is greater than 200,000 new cases detected annually. This number has remained relatively stable during the past eight years, indicating ongoing transmission. The elimination of this disease, remains - a challenge for clinicians and scientists. Since leprosy is an infectious disease, the immune system plays an essential role in its development and progression. The unique immune response in each individual is due to the interaction of various cytokine products, both pro- and anti-inflammatory cytokines. Interleukin-10, an anti-inflammatory cytokine, plays a vital role in the immunity and pathogenesis of leprosy. Evidence suggests that interleukin-10 plays a cruicial roles in the clinical manifestation and progression of the disease in all subtypes of leprosy. An understanding of the biomolecular aspects of this disease is imperative and may lead to the discovery of new treatment-modalities and/or more effective prevention methods.
ABSTRACT
Objective To investigate the roles of inducible costimulatory molecules (ICOS) and related cytokines in the immune regulation of Echinococcus granulosus infections in mice. Methods Eighty BALB/c mice (weight 18–22 g) were divided into the control and infection groups, of 40 animals in each group. E. granulosus infection was modeled in mice by intraperitoneal injection of 10 000 protoscoleces per mouse. Serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) and peripheral interleukin-4 (IL-4) and IL-10 levels were measured 2, 8, 30, 60, 180 days post-infection. Mouse liver specimens were excised for hematoxylin-eosin (HE) staining and immunostaining, and ICOS expression was quantified in mouse liver specimens using quantitative real-time PCR (qPCR) assay. Results There were no significant differences in serum ALT (F = 12.082, P < 0.05), AST (F = 6.347, P < 0.05) or ALP levels (F = 52.186, P < 0.05) in mice 2, 8, 30, 60 and 180 days post-infection with E. granulosus. The serum ALT levels were significantly higher in the infection group than in the control group 2 [(61.72 ± 9.89) vs. (50.65 ± 4.67)U/L, P < 0.05] and 30 days post-infection [(80.61 ± 23.71)vs.(67.75 ± 9.79)U/L, P < 0.05], and the serum ALT levels were significantly higher in the infection group than in the control group 2 [(181.06 ± 60.61) vs.(115.58 ± 17.66)U/L, P < 0.05] and 180 days post-infection [(137.84 ± 29.01) vs. (108.05 ± 10.33) U/L, P < 0.05], while greater serum ALP levels were measured in the infection group than in the control group 2 [(162.90 ± 21.04)vs.(64.54 ± 5.99)U/L, P < 0.05], 8[(176.36 ± 24.56) vs. (62.70 ± 9.21)U/L, P < 0.05] and 30 days post-infection [(138.86 ± 13.59) vs. (58.60 ± 5.28) U/L, P < 0.05]. A few inflammatory cells were seen in mouse liver in the infection group 30 days post-infection, and no apparent changes were found in the mouse hepatic structure 60 days post-infection. On day 180 post-infection, a large number of epithelium-like cells presented fibrotic growth in mouse liver in the cyst-infiltrating regions, with cuticula formation seen, and plenty of red cells were present in lesions and hepatocyte space. Positive ICOS expression was detected in mouse liver in the infection group, with ICOS-positive cells predominantly seen in the cytoplasm of the hepatocyte, and the ICOS expression increased over time. The relative ICOS mRNA expression was 2.732 ± 0.094 on day 180 post-infection, which was significantly greater than that on day 2 postinfection (0.746 ± 0.049). There were no significant differences in serum IL-4 or IL-10 levels at different time points after E. granulosus infections, while the serum IL-4 and IL-10 levels peaked in the infection group 180 days and 60 days post-infection, respectively. Higher serum IL-4 levels were measured in the infection group than in the control group 8 [(22.50 ± 3.24) vs. (5.82 ± 0.49) pg/mL, P < 0.05], 30 [(15.49 ± 4.73) vs. (5.10 ± 1.38) pg/mL, P < 0.05], 60 [(36.93 ± 6.14) vs. (4.13 ± 1.19) pg/mL, P < 0.05] and 180 days post-infection [(198.35 ± 0.70) vs. (4.19 ± 0.98) pg/mL, P < 0.05], and higher IL-10 levels were measured in the infection group than in the control group 2 [(4.84 ± 1.91) vs. (2.11 ± 1.03) pg/mL, P < 0.05], 8 [(44.72 ± 14.63) vs. (3.16 ± 0.60) pg/mL, P < 0.05], 30 [(25.47 ± 8.00) vs. (3.83 ± 1.87) pg/mL, P < 0.05], 60 [(187.16 ± 60.44) vs. (3.69 ± 1.05) pg/mL, P < 0.05] and 180 days post-infection [(85.40 ± 7.15) vs. (3.25 ± 0.93) pg/mL, P < 0.05]. Conclusions High ICOS expression is present in the liver of mice with E. granulosus infections. The positive ICOS expression and immune activation levels increase with the time of E. granulosus infections, leading to aggravation of hepatocyte injury caused by inflammation.
ABSTRACT
@#AIM:To investigate the dynamic expression characteristics of interleukin-10(IL-10)after implantation of glaucoma drainage material, and to reveal the role of IL-10 on scarring formation.METHODS:Totally 75 New Zealand white rabbits were randomly divided into three groups, which were implanted with different types of material-Polymethyl methacrylate coated Parylene C(PMMA group), silicone together with injection of Mitomycin C(MMC)(silicon-MMC group)and silicone(silicone group). Aqueous humor were collected at 1, 3d, 1, 2, 3, 4 and 8wk after operation and enzyme-linked immunosorbent assay(ELISA)were utilized to detect the expression of IL-10 in the aqueous humor. The connective tissue surrounding the material were collected at 1, 2, 3, 4 and 8wk postoperatively. Hematoxylin-eosin(HE)staining was applied to evaluate the proliferation of fibroblasts and the infiltration of inflammatory cells. The protein expression and mRNA of IL-10 in the connective tissue were detected by immunohistochemistry and real-time PCR.RESULTS:Compared with PMMA and silicon-MMC group, silicone group showed significantly increased proliferation of fibroblasts and infiltration of inflammatory cells according to the HE staining result. The result of ELISA showed the expression of IL-10 in the aqueous humor increased significantly at the early stage after surgery, and then decreased gradually,the highest appeared on the third day after operation,and in silicone group there was higher than the other two groups in the early stage postoperatively(1d-3wk)(all <i>P</i><0.05), and there was no significant difference in the late stages(4-8wk). The protein expression and mRNA of IL-10 in connective tissue were the highest in the first week after operation, decreased gradually at 2-3wk after operation, and increased again at 4-8wk after operation by immunohistochemistry and real-time PCR. And the expression was higher in silicone group than in the other two groups at each time point(all <i>P</i><0.05). Furthermore, there was a positive correlation between the expression of IL-10 protein and the proliferation of fibroblasts in the late stages(4-8wk).CONCLUSION: After implantation of glaucoma drainage material, the process of IL-10 increased first, then decreased gradually, and increased again 4wk later, thus IL-10 may be a potential target for inhibiting the scar formation.
ABSTRACT
OBJECTIVE@#To explore the expression levels and clinical significance of helper T cell 1/helper T cell 2 (Th1/Th2) cytokine and interleukin-6 (IL-6) in patients with acute leukemia (AL) complicated by infection.@*METHODS@#68 patients with AL complicated by infection admitted to Wuhan Fifth Hospital from May 2017 to January 2020 were enrolled as study group, 50 AL patients without infection were enrolled as AL group, and 30 healthy volunteers checked in physical examination center were enrolled as healthy control group. The levels of serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-10 (IL-10), and peripheral blood Th1/Th2 cells subsets were measured and compared among the three groups. The serum IL-6, IL-10, TNF-α and Th1/Th2 were compared between the patients with mild to moderate infection (n=52) and septic shock (n=16). The relationship between IL-6, IL-10, TNF-α, Th1/Th2 and AL infection was analyzed.@*RESULTS@#The levels of IL-6, IL-10 , TNF-α, and the proportion of Th2 of the patients in study group and AL group were significantly higher than those in healthy control group (P<0.001), while the proportion of Th1 and Th1/Th2 were significantly lower than those in healthy control group (P<0.001). The levels of IL-6, IL-10 and TNF-α, and the proportion of Th2 the patients in study group were significantly higher than those in AL group (P<0.001), while the proportion of Th1 and Th1/Th2 were significantly lower than those in AL group (P<0.001). The serum IL-6, IL-10 and TNF-α level of the patients in septic shock group were significantly higher than those in mild-to-moderate infection group (P<0.001), while Th1/Th2 was lower than those in mild-to-moderate infection group (P<0.001). The results of ROC curve analysis showed that the area under the ROC curve (AUC) values of IL-6, IL-10, TNF-α and Th1/Th2 alone for the diagnosis of septic shock were 0.779, 0.761, 0.724 and 0.718, which were lower than that their combination (0.910) (P<0.05).@*CONCLUSION@#The levels of serum IL-6, IL-10 and TNF-α are high in patients with AL complicated infection and septic shock, while Th1/Th2 cell subsets is low. The combined detection of serum IL-6, IL-10, TNF-α and Th1/Th2 is a good diagnostic value for predicting the occurrence of severe septic shock.

Objective:This study has investigated the value of detecting cerebrospinal fluid (CSF) MyD88L265P mutation and interleukin-10 (IL-10) levels in the prognosis of PCNSL.Methods:We retrospectively analyzed the clinical data, CSF characteristics (including cytology, cell counting, total protein, and the level of cytokine IL-10) and treatment process of 39 PCNSL patients newly diagnosed by surgery and pathology (18 males and 21 females, aged 40-73 years) from August 2013 to December 2016 in Hua Shan Hospital North. MyD88L265P mutation was detected by digital PCR in 39 paraffin-embedded tissues and 35 cerebrospinal fluid samples. Log-rank test was used for univariate analysis and Cox regression for multivariate analysis to establish the prognosis model of PCNSL which might be related to PCNSL first progress-free survival (PFS) and overall survival (OS).Results:The median age of the 39 PCNSL patients was 59 years old, with 30.8% (12/39) intraocular involvement. The mutation rate of MyD88L265P in tissues and cerebrospinal fluid was 74.4% (29/39) and 40.0% (14/35), respectively. 51.9% (14/27) patients were observed with MyD88L265P mutation in both tissues and CFS. Univariate analysis showed that intraocular involvement, high level of IL-10 in CFS (≥45 pg/ml), and MyD88L265P mutation in CFS are factors significantly influencing median progression-free survival (mPFS) of patients ( P<0.05). Patients with intraocular involvement had shorter OS than those without involvement which was statistically significant ( HR=6.5,95% CI 1.7-47.3, P<0.05). And multivariate analysis showed that intraocular involvement ( HR=2.4, 95% CI 1.3-7.8, P<0.05) and CFS MyD88L265P mutation ( HR=2.1, 95% CI 1.1-5.7, P<0.05) were independent prognostic factors for PFS. Conclusion:The presence of intraocular involvement and MyD88L265P mutation in CFS indicated poor prognosis of PCNSL patients. High CSF IL-10 level was not an independent factor affecting prognosis.
ABSTRACT
Objective:To observe any effect of supplementing treadmill training with applications of the traditional Chinese Songchi ointment in the rehabilitation of gastrocnemius muscles atrophied through disuse.Methods:Forty-five Wistar rats were randomly divided into a normal control group ( n=8) and a model group ( n=37). The rats in the model group had their left hind limbs immobilized by the Nagai method to induce disused muscle atrophy (DMA). That group was then randomly subdivided into a model control (MC) group, a treadmill training group (the EX group), a Songchi ointment group (SC group) and a comprehensive rehabilitation group (the CR group), each of 8. The EX and SC groups were given treadmill training at 18m/min or topical application of Songchi ointment once a day, 6 days a week for 6 weeks. The CR group was given both treatments. After the 6 weeks, hematoxylin and eosin staining was used to evaluate the pathological changes in the gastrocnemius of each rat′s left hind limb. Serum levels of tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β) and interleukin-10 (IL-10) were detected using enzyme-linked immunosorbent assays. PI3K, Akt and mTOR mRNA and protein were assayed using real-time quantitative PCR and western blotting. Results:The arrangement of muscle fibers in the MC group was disordered and there was a large number of infiltrated inflammatory cells. Such conditions were significantly relieved in the CR group. After the intervention the levels of inflammatory factors TNF-α and IL-1β in the CR group were, on average, significantly lower than those observed in the MC group, the EX group or the SC group, while the level of anti-inflammatory factor IL-10 was significantly higher. The average PI3K, Akt and mTOR mRNA and protein levels of group CR were significantly higher than those of the MC and EX groups.Conclusions:The traditional Chinese Songchi ointment can usefully supplement treadmill training to relieve DMA. It upregulates IL-10, activates the PI3K Akt/mTOR signaling pathway and promotes the synthesis of muscle fiber protein while down-regulating TNF-α and IL-1β and muscle fiber inflammatory response.
ABSTRACT
Objective:To investigate the association between hepatic echinococcus granulosus infection and necrosis with gene polymorphism of interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α), and to identify the related factors at the gene level.Methods:A total of 106 patients with hepatic echinococcosis who underwent surgical treatment in the department of hepatobiliary surgery, People′s Hospital of Xinjiang Uygur Autonomous Region from January 2018 to December 2020 were selected. Patients with necrosis caused by hepatic echinococcus granulosus infection were selected as the observation group, and patients without necrosis caused by hepatic echinococcus granulosus infection were selected as the control group, with 53 cases in each group. The serum levels of IL-10 and TNF-α were detected by enzyme-linked immunosorbent assay (ELISA). The polymorphisms of IL-10 (-592, -1082) and TNF-α (rsl800630) were detected by polymerase chain reaction (PCR). The levels of IL-10 and TNF-α and their gene polymorphisms were analyzed.Results:The levels of serum IL-10 and TNF-α in the observation group were significantly higher than those in the control group (all P<0.05); There was significant difference in genotype and allele frequency of IL-10 (-592, -1082) and TNF-α (rsl800630) (all P<0.05). The serum IL-10 level of CC genotype patients with IL-10 gene -592C/A locus in the observation group was higher than that of CA+ AA genotype patients, with statistically significant difference ( P<0.05). The serum IL-10 level in patients with TT genotype at -1082T>A of IL-10 gene in the observation group was higher than that in patients with TA+ AA genotype, with statistically significant difference ( P<0.05). The serum TNF-α level in patients with CC genotype at rsl800630C/A locus of TNF-α gene in the observation group was higher than that in patients with CA+ AA genotype, with statistically significant difference ( P<0.05). Conclusions:The changes of IL-10 (-592, -1082) and TNF-α (rsl800630) gene polymorphisms may be associated with hepatic echinococcus granulosus infection and necrosis.
ABSTRACT
Objective:To investigate the efficacy of Yupingfeng powder combined with extensively hydrolyzed milk formulas in the treatment of milk protein allergy in infants and its effects on immune function, interleukin-10 (IL-10) and IL-22 levels. Methods:Eighty infants with milk protein allergy who received treatment in Hangzhou Children's Hospital from January 2020 to January 2021 were included in this study. They were randomly assigned to Yupingfeng powder and conventional treatment groups, with 40 infants per group. An additional 80 infants who concurrently received health examination in the same hospital were included in the control group. The conventional group was treated with extensively hydrolyzed milk formulas. The Yupingfeng powder group was treated with Yupingfeng powder combined with extensively hydrolyzed milk formulas. All infants were treated for 30 successive days. Clinical efficacy, serum total immunoglobulin (IgE), milk specific IgE (sIgE), peripheral blood CD 4+CD 25+ Treg, IL-10 and IL-22 levels were compared between groups. Results:Total response rate in the Yupingfeng powder group was significantly higher than that in the conventional treatment group [92.50% (37/40) vs. 72.50% (29/40), χ2 = 5.54, P < 0.05]. Serum total IgE and milk sIgE levels in the Yupingfeng powder group were (132.93 ± 14.61) IU/L and (0.62 ± 0.14) IU/L, respectively, which were significantly lower than (150.27 ± 16.22) IU/L and (0.85 ± 0.17) IU/L in the conventional treatment group ( t = 5.02, 6.61, both P < 0.05). The expression of CD 4+CD 25+ Treg in the Yupingfeng powder group was significantly higher than that in the conventional treatment group [(13.29 ± 1.40)% vs. (11.84 ± 1.27)%, t = 4.85, P < 0.05). CD 4+CD 25+ Treg expression in the Yupingfeng powder group was not significantly different from that in the control group [(13.40 ± 2.03)%, t = 0.31, P = 0.759]. IL-10 in the Yupingfeng powder group was significantly higher than that in the conventional treatment group [(34.57 ± 4.07) μg/L vs. (22.19 ± 2.15) μg/L, t = 17.01, P < 0.05]. IL-22 level in the Yupingfeng powder group was significantly lower than that in the conventional treatment group [(2.20 ± 0.42) ng/L vs. (5.28 ± 0.79) ng/L, t = 21.77, P < 0.05]. IL-10 and IL-22 levels in the Yupingfeng powder group were not different from those in the control group [(35.53 ± 3.85) μg/L, (2.13 ± 0.53) ng/L, t = 1.26, P = 0.209; t = 0.73, P = 0.468]. Conclusion:Yupingfeng powder combined with extensively hydrolyzed milk formulas is highly effective on milk protein allergy. The combined therapy can improve the immune function of infants, enhance IL-10 level, and decrease IL-22 level.
ABSTRACT
Objective:To explore the changes of T follicular regulatory (T FR) cells/T follicular helper (T FH) cells and their related cytokines in peripheral blood of children with dust mite allergic asthma, and their clinical significance. Methods:A total of 25 children with acute dust mite allergic asthma (the asthma group) in Affiliated Hospital of Jiangnan University from January to December 2021 and 16 age- and sex-matched healthy volunteers (the healthy control group) at the same time were enrolled in the retrospective study.The percentages of peripheral T FR cells and T FH cells of the 2 groups were measured by flow cytometry.The plasma levels of cytokines[interleukin (IL)-10, IL-21] of the 2 groups were assessed by the flow cytometric microsphere-based array technology.The specific IgE (sIgE) levels of dust mites in 2 groups were detected by fluorescence enzyme immunoassay.The percentage of eosinophils in peripheral blood detected by blood cell analyzer.Data between groups were compared by t-test, and the correlation among indicators was analyzed by Spearman rank correlation analysis. Results:The asthma group had evident T FR cells/T FH cells immune imbalance.Compared with the healthy control group, the asthma group had a significantly lower T FR cells level[(0.11±0.03)% vs.(0.13±0.03)%], a significantly higher T FH cells level[(5.07±1.75)% vs.(3.80 ± 1.60)%], and a significantly lower ratio of T FR cells /T FH cells(0.02±0.01 vs.0.05±0.03) ( t=2.29, 2.30, 3.71; all P<0.05). Compared with the healthy control group, the asthma group had a significantly higher IL-21 level[(547.85±195.13) ng/L vs.(404.94±110.41) ng/L], and a significantly lower IL-10 level[(10.18±3.49) ng/L vs.(14.79±5.65) ng/L] ( t=2.60, 3.15; all P<0.05). The ratio of T FR cells/T FH cells in asthma group was negatively correlated with sIgE ( r=-0.444 2, P=0.026 1), but not related to the eosinophil percentage ( r=-0.135 2, P=0.519 3). Conclusions:Children with dust mite allergic asthma suffer from T FR cells/T FH cells subset imbalance.The imbalanced T FR cells, T FH cells and their related cytokines IL-10 and IL-21 may play a role in regulating the production of asthma sIgE.
ABSTRACT
Inflammatory bowel disease(IBD) is a complex multifactorial disease characterized by chronic recurrent intestinal inflammation.The etiology of IBD has not yet been determined, and relevant studies have focused on the genetic susceptibility, immune response, intestinal microbiome and environmental factors of the host.Studies have found that interleukin-10 receptor A(IL-10RA)plays important roles in the pathogenesis of IBD.IL-10RA can not only affect the intestinal barrier, but also affect the intestinal immune system.Furthermore, the mutation of IL-10RA itself is highly correlated with very early-onset IBD.
