Résumé

ObjectiveTo evaluate the clinical efficacy of modified Houpo Dahuangtang in moderate and severe acute respiratory distress syndrome (ARDS) patients with phlegm-heat accumulation,and monitor the pulmonary ventilation changes of patients before and after treatment by electrical impedance tomography(EIT). MethodThe 62 cases of moderate and severe ARDS patients with phlegm-heat accumulation who required mechanical ventilation in the department of intensive care unit (ICU) in Chongqing Hospital of Traditional Chinese Medicine from September 2021 to June 2022 were selected,and divided into an experimental group(31 cases)and a control group(31 cases)using a random number table. On the basis of regular Western medicine treatment,the experimental group received modified Houpo Dahuangtang and the control group received warm water by a nasogastric tube for seven days. The changes in the clinical efficacy of traditional Chinese medicine(TCM),the oxygenation index[arterial oxygen partial pressure (PaO2)/fractional inspired oxygen(FiO2),P/F],lactic acid(Lac),acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score,compliance,plateau pressure,gas distribution parameters monitored by EIT(Z1,Z2,Z3 and Z4),inflammatory factors[interleukin-6 (IL-6),IL-10, tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP)] of both groups before and after treatment were recorded. Besides, the mechanical ventilation time, length of stay in ICU, 28-day mortality and incidence of adverse reactions(delirium,abdominal pain and diarrhea)in the two groups were also observed. ResultThere was no significant difference in the baseline indexes of patients in the two groups,and thus the two groups were comparable. After treatment for one week, the total effective rate for TCM syndromes in the experimental group was 90.30%(28/31), higher than the 67.74%(21/31)in the control group(Z=-2.415,P<0.05).Compared with the same group before treatment, the plateau pressure and Lac decreased (P<0.01)and the compliance and P/F increased (P<0.01) in experimental group, while the Lac decreased (P<0.05)and the P/F increased (P<0.05), and the compliance and plateau pressure did not change significantly in the control group. After treatment,the plateau pressure and inflammatory factors in the experimental group were lower than those in the control group(P<0.05), but the compliance and P/F in the experimental group were higher than those in the control group(P<0.05), and the gas distribution parameters Z1,Z2,Z3,Z4,Z1+Z2,and Z3+Z4 monitored by EIT in the experimental group were all higher than those in the control group (P<0.05). There was no significant difference in mechanical ventilation time, ICU hospitalization time, 28-day mortality, delirium, abdominal pain, diarrhea and other adverse reactions between the two groups. ConclusionModified Houpo Dahuangtang can significantly improve the P/F,pulmonary ventilation in gravity-dependent regions and pulmonary compliance,reduce the release of inflammatory factors in moderate and severe ARDS patients. Compared with conventional methods,EIT can timely monitor the pulmonary ventilation changes in ARDS patients,which suggests its clinical feasibility.

Résumé

OBJECTIVE To study the effects of Phellodendron amurense polysaccharides (PAP) on improving gouty nephropathy (GN) in rats, and to investigate its mechanism primarily by interfering the p38 mitogen-activated protein kinase (p38 MAPK)/nuclear factor-κB(NF-κB)/tumor necrosis factor-α(TNF-α). METHODS Sixty rats were randomly divided into normal group (water), model group (water), allopurinol group (positive control, 20 mg/kg), PAP high-dose, medium-dose and low-dose groups (100, 50, 25 mg/kg, by raw material) after being stratified by body weight, with 10 rats in each group. Except for the normal group, the other groups were induced to construct GN model by giving 1 500 mg/kg potassium oxazinate and 100 mg/kg adenine intragastrically for 14 days. After modeling, the rats in each group were given relevant medicine/water intragastrically, once a day, for consecutive 28 days. After the last medication, the levels of biochemical parameters related to renal function [uric acid, creatinine (Cr), blood urea nitrogen (BUN), xanthine oxidase (XOD)] were detected in rats, and the histopathological changes in the rat kidney were observed. The protein expressions of monocyte chemoattractant protein-1(MCP-1),TNF-α and interleukin-6(IL-6) as well as the phosphorylation levels of p38 MAPK and NF-κB p65 protein were determined in renal tissue of rats. RESULTS Compared with the normal group, the model group suffered from the dilatation of renal tubules, structural damage to glomeruli, accompanied by inflammatory infiltration and fibrosis; the contents of uric acid, Cr, BUN and XOD, the protein expressions of MCP-1,TNF-α and IL-6 and the phosphorylation levels of p38 MAPK and NF-κB p65 protein were all increased significantly (P<0.05 or P<0.01). Compared with the model group, the pathological symptoms of renal tissue in rats had been improved to varying degrees in different dose groups of PAP; the contents of uric acid, Cr, BUN and XOD, protein expressions of MCP-1, TNF-α and IL-6, the phosphorylation levels of p38 MAPK and NF-κB p65 protein in PAP high-dose and PAP medium-dose groups were all decreased significantly (P<0.05 or P<0.01). CONCLUSIONS PAP exhibits an anti-GN effect, the mechanism of which may be associated with inhibiting the p38 MAPK/NF-κB/TNF-α signaling pathway.

Résumé

BackgroundBariatric surgery has emerged as an important tool in the management of obesity. Some patients undergoing bariatric surgery are prone to develop emotional abnormalities and have abnormally elevated concentrations of inflammatory factors level in peripheral blood, whereas current domestic research focusing on the impact of preoperative emotional states and peripheral blood inflammatory factors level on weight loss effect remains limited. ObjectiveTo explore the correlation of preoperative emotional abnormalities with the effectiveness of bariatric surgery in obese patients, and to provide theoretical basis for improving the clinical efficacy of bariatric surgery. MethodsEighty-one obese patients scheduled for bariatric surgery at gastrointestinal surgery Department of West China Hospital, Sichuan University from December 30, 2022 to June 30, 2023 were enrolled and assessed using Hamilton Depression Scale-17 item (HAMD-17) and Hamilton Anxiety Scale (HAMA). Patients who scored 7 or above on HAMD-17 or HAMA or had a history of previous depression or anxiety diagnoses were classified into emotional abnormality group (n=34), and samples who scored less than 7 on HAMD-17 and HAMA and were free of history of previous depression and anxiety diagnoses were set as non-emotional abnormality group (n=47). The data were collected by the self made questionnaire. Patients were subjected to complete the assessment of Beck Scale for Suicide Ideation-Chinese Version (BSI-CV), Eating Disorder Inventory (EDI) and Pittsburgh Sleep Quality Index (PSQI). Laboratory tests including peripheral blood C-reactive protein (CRP) and interleukin-6 (IL-6). Body weight and height assessed in the early morning after an overnight fasting period were recorded in all participants at 1- and 6-month after surgery through outpatient clinic visits or telephone follow-up. Pearson correlation coefficient was used to examine relationship among body mass index (BMI), preoperative emotional states and peripheral blood inflammation mediators. ResultsAmong 81 obese patients, 62 completed the study, including 27 cases in emotional abnormality group and 35 cases in non-emotional abnormality group. Emotional abnormality group scored higher on BSI-CV (current), BSI-CV (worst), EDI and PSQI, and detected higher levels of CRP and IL-6 compared with non-emotional abnormality group (Z=2.677, 2.975, t=3.573, 4.035, 1.990, 2.799, P<0.05 or 0.01). For BMI, there was no significant group effect and time×group interaction effect (P>0.05), but a significant time effect (F=227.740, P<0.01). Within emotional abnormality group, BMI at the baseline, 1- and 6-month after surgery showed a positive correlation with IL-6 level (r=0.419, 0.510, 0.559, P<0.05 or 0.01), BMI at 6-month after surgery was positively correlated with HAMD-17 total score (r=0.390, P<0.05), and ΔBMI% at 6-month after surgery was negatively correlated with HAMD-17 total score (r=-0.421, P<0.05). Within non-emotional abnormality group, baseline BMI was positively correlated with IL-6 level (r=0.338, P<0.01). ConclusionThe short-term effect of bariatric surgery may be comparable in obese patients with or without emotional abnormalities, while it cannot be ruled out whether the outcome of bariatric surgery is related to the severity of preoperative depression.

Résumé

OBJECTIVE@#To investigate the effects of Danmu Extract Syrup (DMS) on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice and explore the mechanism.@*METHODS@#Seventy-two male Balb/C mice were randomly divided into 6 groups according to a random number table (n=12), including control (normal saline), LPS (5 mg/kg), LPS+DMS 2.5 mL/kg, LPS+DMS 5 mL/kg, LPS+DMS 10 mL/kg, and LPS+Dexamethasone (DXM, 5 mg/kg) groups. After pretreatment with DMS and DXM, the ALI mice model was induced by LPS, and the bronchoalveolar lavage fluid (BALF) were collected to determine protein concentration, cell counts and inflammatory cytokines. The lung tissues of mice were stained with hematoxylin-eosin, and the wet/dry weight ratio (W/D) of lung tissue was calculated. The levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and IL-1 β in BALF of mice were detected by enzyme linked immunosorbent assay. The expression levels of Claudin-5, vascular endothelial (VE)-cadherin, vascular endothelial growth factor (VEGF), phospho-protein kinase B (p-Akt) and Akt were detected by Western blot analysis.@*RESULTS@#DMS pre-treatment significantly ameliorated lung histopathological changes. Compared with the LPS group, the W/D ratio and protein contents in BALF were obviously reduced after DMS pretreatment (P<0.05 or P<0.01). The number of cells in BALF and myeloperoxidase (MPO) activity decreased significantly after DMS pretreatment (P<0.05 or P<0.01). DMS pre-treatment decreased the levels of TNF-α, IL-6 and IL-1 β (P<0.01). Meanwhile, DMS activated the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) pathway and reversed the expressions of Claudin-5, VE-cadherin and VEGF (P<0.01).@*CONCLUSIONS@#DMS attenuated LPS-induced ALI in mice through repairing endothelial barrier. It might be a potential therapeutic drug for LPS-induced lung injury.

Résumé

SUMMARY: The 12C6+ heavy ion beam irradiation can cause bystander effects. The inflammatory cytokines, endocrine hormones and apoptotic proteins may be involved in 12C6+ irradiation-induced bystander effects. This study characterized the protective effects and mechanisms of Huangqi decoction (HQD) against 12C6+ radiation induced bystander effects. Wistar rats were randomly divided into control, 12C6+ heavy ion irradiation model, and high-dose/medium-dose/low-dose HQD groups. HE staining assessed the pathological changes of brain and kidney. Peripheral blood chemical indicators as well as inflammatory factors and endocrine hormones were detected. Apoptosis was measured with TUNEL. Proliferating cell nuclear antigen (PCNA) expression was determined with real-time PCR and Western blot.Irradiation induced pathological damage to the brain and kidney tissues. After irradiation, the numbers of white blood cells (WBC) and monocyte, and the expression of interleukin (IL)-2, corticotropin-releasing hormone (CRH) and PCNA decreased. The damage was accompanied by increased expression of IL-1β, IL-6, corticosterone (CORT) and adrenocorticotropic hormone (ACTH) as well as increased neuronal apoptosis. These effects were indicative of radiation-induced bystander effects. Administration of HQD attenuated the pathological damage to brain and kidney tissues, and increased the numbers of WBC, neutrophils, lymphocyte and monocytes, as well as the expression of IL-2, CRH and PCNA. It also decreased the expression of IL-1β, IL-6, CORT and ACTH as well as neuronal apoptosis. HQD exhibits protective effects against 12C6+ radiation-induced bystander effects. The underlying mechanism may involve the promotion of the production of peripheral blood cells, inhibition of inflammatory factors and apoptosis, and regulation of endocrine hormones.


La irradiación con haz de iones pesados 12C6+ puede provocar efectos secundarios. Las citoquinas inflamatorias, las hormonas endocrinas y las proteínas apoptóticas pueden estar involucradas en los efectos secundarios inducidos por la irradiación 12C6+. Este estudio caracterizó los efectos y mecanismos protectores de la decocción de Huangqi (HQD) contra los efectos externos inducidos por la radiación 12C6+. Las ratas Wistar se dividieron aleatoriamente en grupos control, modelo de irradiación de iones pesados 12C6+ y grupos de dosis alta/media/baja de HQD. La tinción con HE evaluó los cambios patológicos del cerebro y el riñón. Se detectaron indicadores químicos de sangre periférica, así como factores inflamatorios y hormonas endocrinas. La apoptosis se midió con TUNEL. La expresión del antígeno nuclear de células en proliferación (PCNA) se determinó mediante PCR en tiempo real y transferencia Western blot. La irradiación indujo daños patológicos en los tejidos cerebrales y renales. Después de la irradiación, disminuyó el número de glóbulos blancos (WBC) y monocitos, y la expresión de interleucina (IL)-2, hormona liberadora de corticotropina (CRH) y PCNA. El daño estuvo acompañado por una mayor expresión de IL-1β, IL-6, corticosterona (CORT) y hormona adrenocorticotrópica (ACTH), así como un aumento de la apoptosis neuronal. Estas alteraciones fueron indicativas de efectos inducidos por la radiación. La administración de HQD atenuó el daño patológico a los tejidos cerebrales y renales, y aumentó el número de leucocitos y monocitos, así como la expresión de IL-2, CRH y PCNA. También disminuyó la expresión de IL-1β, IL-6, CORT y ACTH, así como la apoptosis neuronal. HQD exhibe mecanismos protectores contra los efectos externos inducidos por la radiación 12C6+. El mecanismo subyacente puede implicar la promoción de la producción de células sanguíneas periféricas, la inhibición de factores inflamatorios y la apoptosis y la regulación de hormonas endocrinas.

Résumé

Purpose: To study ocular surface signs, symptoms, and tear film composition following prophylactic thermal pulsation therapy (TPT) prior to refractive surgery, and to compare these outcomes with those who underwent TPT after refractive surgery. Methods: Patients with mild?to?moderate evaporative dry eye disease (DED) and/or meibomian gland dysfunction (MGD) undergoing refractive surgery were included. Group 1 patients received TPT (LipiFlow) prior to laser?assisted in situ keratomileusis (LASIK; n = 32, 64 eyes), and Group 2 patients received TPT three months after LASIK (n = 27, 52 eyes). Ocular Surface Disease Index (OSDI) score, Schirmer’s test (ST1, ST2), Tear Breakup Time (TBUT), meibography, and tear fluid were obtained preoperatively and at three months postoperatively in Groups 1 and 2. Additional postoperative evaluation was performed three months after TPT in Group 2. Tear soluble factor profile was measured by multiplex enzyme?linked immunosorbent assay (ELISA) using flow cytometry. Results: Postoperative OSDI score was significantly lower and TBUT was significantly higher when compared with matched preoperative values of Group 1 participants. On the other hand, the postoperative OSDI score was significantly higher and TBUT significantly lower when compared with matched preoperative values of Group 2 participants. TPT significantly reduced the postoperative elevation in OSDI and significantly reduced the postoperative reduction in TBUT in Group 2 participants. Tear Matrix metalloproteinase?9/ Tissue inhibitor matrix metalloproteinase 1 (MMP?9/TIMP1) ratio was significantly higher, postoperatively, when compared with matched preoperative levels in Group 2. However, MMP9/TIMP1 ratio remained unaltered in Group 1 participants. Conclusion: TPT prior to refractive surgery improved postsurgical ocular surface signs and symptoms and reduced tear inflammatory factors, thereby suggesting the plausibility of reduced post?refractive surgery DED in patients.

@#Objective To investigate the effect of cold stimulation on the phenotype of alveolar macrophages(MH-S cells) in mice. Methods MH-S cells were cultured at 37 ℃ for 24 h,and cold stimulated at 36,34 and 32 ℃ for 0,0. 5,1,3,6,9 and 12 h respectively. The mRNA transcription levels of interleukin-1β(IL-1β) and interleukin-10(IL-10) genes in MH-S cells were detected by qRT-PCR. MH-S cells were cultured at 37 ℃ for 24 h,and cold stimulated at 34 ℃ for 0. 5 h,which were detected for the mRNA transcription levels of tumor necrosis factor-α(TNF-α),inducible nitric oxide synthase(iNOS)and Arginase1(Arg1)genes by qRT-PCR(MH-S cells with 0 h cold stimulation as control),detected for the expression of iNOS and Arg1 by immunofluorescence assay(MH-S cells cultured at 37 ℃ for 0. 5 h as negative control)and detected for the expression levels of iNOS,TNF-α and nuclear factor-kappa B(NF-κB)by Western blot(MH-S cells cultured at 37 ℃ for 0. 5 h as negative control). Results The mRNA transcription levels of IL-1β and IL-10 genes in MH-S cells were the highest when the cells were cultured at 34 ℃ for 0. 5 h,therefore,the cold stimulation model of MH-S cells was established under this condition. Compared with the cells cultured for 0 h,the mRNA transcription levels of iNOS,TNF-α and Arg1genes in MH-S cells cultured at 34 ℃ for 0. 5 h increased significantly(t = 3. 733,12. 190 and 6. 793,respectively,each P < 0. 05). Compared with the negative control group,the fluorescence expression intensity of iNOS and Arg1 in MH-S cells in the stimulation group increased,especially iNOS,the expression levels of iNOS and TNF-α proteins increased with no significant difference(t = 0. 675 and 1. 514,respectively,each P > 0. 05),and the expression level of NF-κB increased significantly(t = 3. 092,P < 0. 05). Conclusion Cold stimulation at 34 ℃ for 0. 5 h can increase the expression of inflammatory factors such as IL-1β,IL-10,TNF-α,iNOS,Agr1 and NF-κB in MH-S cells,activate NF-κB signaling pathway in MH-S cells,induce the expression of inflammatory proteins and promote cell activation.

Objective:To explore the effects of different doses of dexmedetomidine (DEX) on inflammatory factors and immune function in patients with gynecological malignant tumors who underwent laparoscopic surgery.Methods:A total of 60 patients with gynecological malignant tumors who underwent laparoscopic surgery from January 2021 to December 2021 in the Second Hospital of Shanxi Medical University were selected as the research objects. All patients were divided into the control group, low-dose DEX group (group D1) and high-dose DEX group (group D2) by using random number table method, 20 cases in each group. Patients in D1 and D2 groups were intravenously pumped DEX 0.5 μg/kg and 1.0 μg/kg 10 minutes before induction of anesthesia, and then maintained with DEX 0.5 μg·kg -1·h -1 and 1.0 μg·kg -1·h -1 until 30 minutes before the end of operation; and patients in the control group were given the same amount of Nacl solution. The 10 ml peripheral venous blood were collected at 10 minutes before induction of anesthesia (T 1), 1 h after pneumoperitoneum relief (T 2) and 24 h after pneumoperitoneum relief (T 3). The changes of interleukin-6 (IL-6), interleukin-10 (IL-10), the proportion of CD4 +, the proportion of CD8 + and CD4 +/CD8 + ratio of the three groups were compared, and the cases of bradycardia and hypotension in perioperative period and the time of first exhaust after operation were recorded. Results:At T 1,T 2 and T 3, the expression level of IL-6 in the control group was (7.95±0.26) pg/ml, (8.30±0.24) pg/ml and (8.35±0.28) pg/ml, respectively, and the difference was statistically significant ( F = 14.14, P < 0.001); the expression level of IL-10 in the control group was (38.9±2.6) pg/ml, (44.5±6.6) pg/ml and (46.3±4.6) pg/ml, respectively, and the difference was statistically significant ( F = 12.45, P < 0.001); the proportion of CD4 + in the control group was (38.5±2.1)%, (29.5±4.6)% and (29.6±3.5)%, respectively, and the difference was statistically significant ( F = 40.82, P < 0.001); the ratio of CD8 + in the control group was (30.1±3.7)%, (35.1±6.3)% and (40.3±8.2)%, respectively, and the difference was statistically significant ( F = 13.02, P < 0.001); the CD4 +/CD8 + ratio in the control group was 1.29±0.14, 0.84±0.09 and 0.75±0.14, respectively, and the difference was statistically significant ( F = 99.94, P < 0.001). The expression level of IL-6 in group D1 and group D2 was (8.10±0.32) pg/ml and (8.01±0.30) pg/ml at T 2, and (8.12±0.35) pg/ml and (8.05±0.34) pg/ml at T 3,which were lower than those in the control group, and the differences were statistically significant (all P < 0.05). The expression level of IL-10 in group D2 was (40.6±3.5) pg/ml at T 2, which was lower than that in the control group, and the difference was statistically significant ( P < 0.05). At T 3, the expression level of IL-10 in group D1 and group D2 was (43.7±3.5) pg/ml and (42.4±3.9) pg/ml, which were lower than those in the control group, and the differences were statistically significant (all P < 0.05). At T 2, the proportion of CD4 + in group D2 was (34.5±4.3)%, which was higher than that in the control group, and the difference was statistically significant ( P < 0.05). At T 3, the proportion of CD4 + in group D1 and group D2 was (32.1±4.2)% and (33.7±2.8)%, which were higher than those in the control group, and the differences were statistically significant (all P < 0.05). At T 2, the proportion of CD8 + in group D2 was (30.7±5.5)%, which was lower than that in the control group, and the difference was statistically significant ( P < 0.05). At T 3, the proportion of CD8 + in group D1 and group D2 was (35.4±5.8)% and (32.5±5.1)%, which were lower than those in the control group, and the differences were statistically significant (all P < 0.05). The CD4 +/CD8 + ratio in group D1 and D2 was 0.99±0.17 and 1.14±0.16 at T 2, 0.93±0.19 and 1.05±0.16 at T 3, which were higher than those in the control group, and the differences were statistically significant (all P < 0.05). Meanwhile, 1 case of hypotension occurred in the the control group and group D1, respectively; 3 cases of bradycardia and 2 cases of hypotension occurred in the group D2. The time of exhaust in the control group was later than that in group D1 and D2, and the difference was statistically significant ( P < 0.05). Conclusions:DEX can inhibit the inflammatory reaction during laparoscopic surgery in patients with gynecological malignant tumors, reduce immune damage. The anti-inflammatory action and immune protection of high-dose of DEX is more significant compared with low-dose of DEX, while high dose of DEX is more likely to cause hemodynamic fluctuations in perioperative period.

Objective:To observe any effect of ultrashortwave (USW) therapy on inflammatory cytokines and the MAPK pathway of rats with a spinal cord injury.Methods:Seventy-nine Sprague-Dawley rats were randomly divided into a control group ( n=35), an intervention group ( n=35) and a sham group ( n=9). Allen′s method was used to establish a contusion model of SCI in the rats of the control and intervention groups, while the sham group′s spinal tissues were exposed but not stricken. Beginning twenty-four hours after SCI modeling, the intervention group was given 7min of USW therapy daily, five days a week till the day of sacrifice for sampling the target area of spinal cord for tests. Then, motion function was evaluated using Basso, Beattie and Bresnahan (BBB) scoring. One, three and seven days after the SCI modeling, immunofluorescence and western blotting were employed to observe any changes in inflammatory factors and the MAPK pathway in the lesioned area. Results:Fourteen days after the modeling the average BBB score of the intervention group was significantly higher than the control group′s average. Moreover, 7 days after the modeling the average content of the domains containing protein 3 (NLRP3), interleukin-6 (IL-6), IL-6 receptor and tumor necrosis factor-α (TNF-α) in the target area of the spinal cord of sham group showed significantly lower levels than in the other 2 groups. And the levels in the intervention group were significantly lower than in the control group. Seven days after the modeling the number of cells positive for zinc finger protein 36 (TTP) in the lesioned area of the intervention group was significantly greater than among the control group. At the same time the levels of MAPK-activated protein kinase 2 (MK2), phosphorylated-mitogen-activated protein kinase-activated version (p-MK2) and TTP in the control and intervention groups were significantly higher than in the sham group. And there were significant differences between the intervention group and control group in the levels of MK2, p-MK2 and TTP.Conclusion:Ultrashortwave therapy can inhibit inflammation by regulating the MAPK inflammatory pathway, promoting the recovery of motion functions, at least in rats.

Résumé

ObjectiveTo explore the effect of Babaodan (BBD) on the NOD-like receptor pyrin domain containing 3/cysteine aspartate-specific protease-3 (NLRP3/Caspase-1) pathway proteins in mice with acetaminophen (APAP)-induced acute liver injury. MethodC57BL/6 mice were randomly grouped, and BBD (75, 150, 300 mg·kg-1, ig) was administered twice a day for three days. After 2 hours of the last administration, the mice were treated with APAP (400 mg·kg-1, ip), and the eyeballs were removed to collect blood after 14 hours. Then they were sacrificed by cervical dislocation for sample collection. Hematoxylin-eosin (HE) staining was used to observe the morphological changes of liver tissue cells, and biochemical methods were used to detect the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), superoxide dismutase (SOD), malondialdehyde (MDA) and myeloperoxidase (MPO) in serum of mice in each group. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was performed to determine the mRNA expression of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-6, and Western blot was performed to determine the protein expression of cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), NLRP3, Caspase-1 and IL-18 in the liver of mice. ResultCompared with the conditions in normal group, the hepatic lobule structure of mice in the model group was partially destroyed, and the hepatic sinusoids were dilated. And the expression levels of ALT and AST in serum, the protein levels of NLRP3, Caspase-1, iNOS, IL-18 and COX-2 and the mRNA levels of IL-1β, IL-6 and TNF-α were increased (P<0.05, P<0.01). Compared with the model group, the administration groups had improvement in liver cell rupture and hepatic sinusoidal compression, and a dose-dependent decrease in the levels of ALT and AST in serum as well as the protein levels of NLRP3, Caspase-1, iNOS, IL-18 and COX-2 and the the mRNA levels of IL-1β, IL-6 and TNF-α in liver tissue (P<0.05, P<0.01). ConclusionBBD can reduce APAP-induced acute liver injury in mice. The mechanism may be related to anti-oxidative stress, inhibition of NLRP3/Caspase-1 pathway, and decreased expression levels of IL-1β, IL-18, TNF-α and IL-6.

Résumé

AIM: To investigate the preventive and therapeutic effects of Hawthorn flavone on hyperlipidemia and atherosclerosis rats. METHODS: The atherosclerosis model was established by high fat diet plus vitamin D2. The blood lipid levels, heart index, atherosclerosis index (AI1, AI2) and coronary heart index were measured in each group. The histopathological changes of aorta were observed by oil red O staining, HE staining and Masson staining. ELISA experiments were used to detect IL-6, ICAM-1, MCP-1 and VCAM-1 protein level. RESULTS: Compared with normal group, total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-C), heart index, atherosclerosis index (AI1, AI2) and coronary index in atherosclerosis model group were significantly increased (P<0.01), while high density lipoprotein cholesterol (HDL-C) was significantly decreased (P<0.01). The pathological score of aorta and the degree of fibrosis were significantly increased (P<0.01). Compared with model group, TC, TG, LDL-C, heart index, atherosclerosis index (AI1, AI2) and coronary heart index were significantly decreased (P<0.01), and high-density lipoprotein cholesterol (HDL-C) was significantly increased (P<0.01) in medium, high dose hawthorn flavonoids and atorvastatin groups. The pathological score of aorta significantly decreased and the degree of fibrosis significantly improved (P<0.01). The variation trend of blood lipid levels in hyperlipidemia rats is basically consistent with atherosclerotic rats. Meanwhile, compared with model group, the medium, high dose hawthorn flavonoids and atorvastatin groups could significantly inhibit the expression levels of IL-6, MCP-1, ICAM-1 and VCAM-1 adhesion molecules (P<0.01). CONCLUSION: The hawthorn flavone can inhibit the formation of aortic endothelial atherosclerotic plaque, reduce the degree of fibrosis and inflammation of atherosclerotic plaque in rats, and achieve the purpose of anti-atherosclerosis. Meanwhile, the hawthorn flavone has the effect of regulating blood lipid.

Résumé

AIM: To explore the possible mechanism of Xiaokeshu recipe in the treatment of type 2 diabetes mellitus (T2DM) by observing the effects of Xiaokeshu Recipe on serum inflammatory factors. METHODS: Male SPF-grade SD rats were fed with high-fat and high-sugar fodder combined with intraperitoneal injection of streptozotocin (STZ) to prepare the model of T2DM. The model rats were randomly divided into a model group,a metformin group, low and high-dose Xiaokeshu recipe groups, and a normal group was set up. After successful modeling, the metformin group and the Xiaokeshu recipe groups were treated with metformin and Xiaokeshu recipe by gavage respectively, normal saline was given by gavage in the normal group and the model group. The general living status of rats before and after treatment was observed. After 4 weeks of drug intervention, serum samples and ileum tissue of rats were collected for biochemical and Western blot. RESULTS: As compaed with the model group,the polydipsia and polyuria in the low and high-dose Xiaokeshu recipe and the metformin groups could be improved. As compaed with the model group, the levels of fasting blood glucose (FBG), fasting insulin (FINS) and interleukin-1β (IL-1β) of rats in the low-dose Xiaokeshu recipe group were decreased, but the differences were statistically insignificant (P0.05), the levels of FBG, FINS and IL-1β of rats in the high-dose Xiaokeshu recipe and the metformin groups were significantly decreased as compared with the the model group (P 0.05 or P0.01). As compaed with the model group, the levels of Lipopolysaccharide (LPS), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in the high-dose Xiaokeshu recipe and the metformin groups were decreased (P<0.05 or P<0.01). As compared with the model group, the expressions of toll-like receptor 4 (TLR4) and nuclear transcription factor (NF-κB) protein in ileal tissue were down-regulated in the low and high-dose Xiaokeshu Recipe and the metformin groups (P<0.05 or P<0.01). CONCLUSION: Xiaokeshu recipe may reduce the level of serum LPS, inhibit the TLR4/NF-κB signaling pathway, and reduce the release of inflammatory factors, thus improving insulin resistance and reducing the blood sugar of the body.

Résumé

Aim To investigate the effect of the aryl hydrocarbon receptor (AhR) on the expression of inflammatory factors in macrophages RAW264. 7 induced by pyocyanin (PCN) and the regulatory mechanism of its signaling pathway. Methods RAW264. 7 cells were treated with different concentrations of PCN for 24 h, respectively, and the effect of PCN on cell activity was detected by CCK8 assay to determine the optimal PCN concentration for manufacturing infection models. The cells were divided into the control group (given 0. 1% dimethyl sulfoxide DMSO), PCN group, PCN + AhR inhibitor (CH223191) group, and PCN + AhR agonist (FICZ) group, and the expression of AhR was detected by immunofluorescence. The expression levels of inflammatory factors (IL-6, IL-1β, and TNF-α) were detected by ELISA. The protein expression of AhR, pp38 MAPK and p-p65NF-κB, was detected by Western blotting. Results PCN induced a significant quantitative effect on AhR expression in RAW264. 7 cells. CH223191 increased PCN-induced inflammatory factor secretion and enhanced the phosphorylation of p38MAPK and p65NF-κB compared with the control group. FICZ decreased PCN-induced inflammatory factor production and reduced the phosphorylation of p38MAPK and p65NF-κB phosphorylation capacity. Conclusions AhR can regulate PCN-induced inflammatory factor expression in RAW264. 7 cells, and the p38MAPK/p65NF-κB signaling pathway may be an essential pathway for the involvement of AhR in immune regulation.
