RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Aim To compare the effects of different time sequence interventions on virus infected mice by using oseltamivir (Tamiflu) as a "tool drug" in view of the current situation of the too early the administration time of antiviral in vivo experiment, so as to provide a basis for selecting a reasonable model intervention time point for antiviral drug research. Methods Balb/c mice were randomly divided into six groups. The virus infection model was established by intranasal infection with influenza virus (0.25 TCID50). Tamiflu-1 group and Tamiflu-2 group were administered orally on 1st and 4th day after exposure. The body mass, survival rate, organ index, viral load and inflammatory factor content were measured. Results Compared with the blank control group, the body weight of the mice in the model group decreased and the lung index increased significantly (P < 0.05). The expression levels of 13 inflammatory factors in model 2 group were significantly different ( P < 0.05). Compared with the model-1 group ,the lung index and spleen index of the Tamiflu-1 group decreased significantly (P < 0.05). Compared with the mode-2 group,the lung index in the Tamiflu-2 group was significantly lower (P <0.05) ,and the thy-mus index was significantly higher (P<0.05). The viral load was 0. 03 times that of the model-2 group. The expression levels of 13 inflammatory factors were significantly different (P < 0. 05). Conclusions The symptoms of the mice in Scheme 2 are more obvious and stable after exposure. After administration, the lung inflammation damage is alleviated. Considering the latency, drug intervention is in line with the drug indications when the model animals show symptoms. It will be more reasonable and accurate whether in the model evaluation or drug evaluation.

RESUMEN

@#The study of children who experienced with febrile seizures(FS) as a result of COVID-19 infection to gain insight into the clinical characteristics and prognosis of neurological damage, with the aim of improving prevention, diagnosis, and the treatment of neurological complications. This study investigated the clinical features of 53 children with FS who were admitted to Sanya Women and Children’s Hospital from December 1, 2022, to January 31, 2023. The results indicated that the duration of convulsion in the case and control group was 7.90±8.91 and 2.67±1.23 (minutes) respectively. The analysis reveals that convulsions occurred within 24 hours in 39 cases (95.12%) of the case group, and in 8 cases (66.7%) of the control group. The difference was statistically significant (P<0.05). Additionally, the case group presented lower counts of WBC and NEU compared to the control group (p<0.05). The findings indicate that convulsions manifest at earlier stages of COVID-19 in children and the last longer than in the control group. It is therefore crucial for healthcare workers to remain attentive to patients with COVID-19 who report fever within 24 hours, and act promptly to implement preventive measures, particularly in cases of prolonged fever. It is essential to integrate the clinical manifestation, particularly convulsions, and the continuous numerical changes of inflammatory factors to assess COVID-19 linked with febrile seizures. In addition, larger-scale multi-center and systematic research are necessary to aid clinicians in monitoring neuropathological signals and biological targets, enabling more equitable diagnosis and treatment plans.

RESUMEN

ObjectiveTo explore the clinical efficacy of percutaneous transforaminal endoscopic spine system (TESSYS) in the treatment of lumbar disc herniation (LDH) complicated with nerve root canal stenosis. MethodsA retrospective study was done on 40 LDH patients complicated with nerve root canal stenosis who underwent TESSYS in our hospital from April 2019 to April 2021. The clinical efficacy of the patients was evaluated by the modified Mac Nab criteria 12 months after the surgery. We also measured and analyzed the scores of visual analogue scale (VAS), Oswestry disability index (ODI) and Japanese orthopaedic association (JOA), the changes of structural parameters of lumbar spine and inflammatory factor levels preoperatively, 6 and 12 months after the surgery. ResultsAll the 40 cases successfully underwent the surgery and follow-ups, with a 12-month post-operative clinical excellent and good rate of 90%. The preoperative, 6-month and 12-month post-operative VAS scores were (7.38±2.06), (2.36±0.87) and (1.62±0.82), respectively. The respective ODI scores were (55.54±11.19), (26.52±7.61) and (18.14±4.36); JOA scores (13.93±2.10), (20.26±1.35) and (22.34±1.88). The post-operative scores of VAS, ODI and JOA were significantly improved compared with those before the surgery (P<0.05). The preoperative and post-operative lumbosacral angles were (37.23±6.84)° and (27.37±4.31)°, respectively, with the respective lumbar curvatures of (13.48±3.06) mm and (22.36±4.51) mm. The post-operative lumbosacral angle and lumbar curvature were significantly improved compared with those before the surgery (P<0.05). The preoperative and post-operative high-sensitivity C-reactive protein (hs-CRP) levels were (3.43±0.61) mg/L and (5.18±0.70) mg/L, respectively, with the respective tumor necrosis factor alpha (TNF-α) levels of (1.44±0.27) mg/L and (2.07±0.44) mg/L. The post-operative levels of hs-CRP and TNF-α were significantly higher than those before the surgery (P<0.05). ConclusionIn the treatment of LDH complicated with nerve root canal stenosis, TESSYS achieves a good clinical effect, improves the structure and function of the lumbar spine, reduces the degree of lumbar spine pain, and has a mild post-operative inflammatory reaction.

RESUMEN

AIM: To investigate the expression level of inflammatory factors of aqueous humor before trabeculectomy in binocular chronic primary angle-closure glaucoma(CPACG)and its correlation with postoperative filtration bleb and intraocular pressure.METHODS: A total of 15 cases(30 eyes)with binocular CPACG who admitted to the Affiliated Eye Hospital of Nanjing Medical University from September to December 2021 and received trabeculectomy were selected. The surgery interval between two eyes was 7d, and the preoperative expression levels of monocyte chemoattractant protein-1(MCP-1), interleukin-17(IL-17), transforming growth factor-β(TGF-β), and interferon-γ(IFN-γ)of the aqueous humor in both eyes were respectively detected by enzyme-linked immunosorbent assay(ELISA). Furthermore, the intraocular pressure(IOP)and the morphology of filtering blebs at 1mo after surgery were measured.RESULTS: The concentrations of MCP-1, IL-17, TGF-β, and IFN-γ in aqueous humor from the first eye before surgery were 330.4±46.2, 357.3±46.9, 2347.5±363.8 and 527.7±101.6pg/mL respectively, and those concentrations in aqueous humor from the fellow eye were 298.2±40.7, 309.1±53.5, 1938.3±426.0 and 628.2±104.9pg/mL respectively. The preoperative expression levels of inflammatory factors of aqueous humor in both eyes were statistically significant(P≤0.05). Furthermore, the expression levels of IL-17 and TGF-β in the aqueous humor of patients with CPACG correlated with IOP and the height of filtering blebs at 1mo after surgery(P&#x0026;#x003C;0.05).CONCLUSION: There may be changes in the expression levels of inflammatory factors of aqueous humor in the fellow eye after surgery of the first eye. Moreover, the preoperative expression level of IL-17 and TGF-β in aqueous humor possibly related to postoperative IOP and the height of filtering bleb.

RESUMEN

ObjectiveTo investigate the changes of differential metabolites in the serum of mice at different stages of bleomycin sulfate(BLM)-induced pulmonary fibrosis modeling and administration, and the mechanism of Wenfei Huaxian granules(WHG)against idiopathic pulmonary fibrosis. MethodMice were randomly divided into control group, control group of 14 days, model group, model group of 14 days, low-dose WHG group and high-dose WHG group. BLM(0.04 U per mouse)was injected into the trachea of mice in the model group, model group of 14 days, low-dose WHG group and high-dose WHG group, and sterile normal saline was injected into the trachea of mice in the control group and control group of 14 days. Mice of low-dose WHG group and high-dose WHG group were given different doses of WHG by gavage every day after injection of BLM, and mice of control group, control group of 14 days, model group and model group of 14 days were given sterile water by gavage every day. The peripheral blood of mice in the control group of 14 days and model group of 14 days were taken to prepare serum after injection of BLM for 14 days, and the peripheral blood and other materials of mice in the other groups were taken after continuous administration for 28 days. The bronchoalveolar lavage fluid(BALF)was collected for leucocyte differential count, the pathological examination and hydroxyproline(HYP)content determination of lung tissues of mice were performed, and the small molecule metabolites in serum samples of mice in each group were determined by ultra-high performance liquid chromatography-mass spectrometry(UHPLC-MS). Principal component analysis(PCA)and orthogonal partial least squares-discriminant analysis(OPLS-DA)were conducted to screen differential metabolites and their biological functions were analyzed. ResultCompared with the control group, a large number of continuous fibrotic foci appeared in the lung tissue of mice in the model group, the alveolitis score, fibrosis degree score and HYP content increased significantly(P<0.01), and the total number of leukocytes, macrophages and lymphocytes in BALF increased significantly(P<0.05). A total of 33 differential metabolites were screened between the control group of 14 days and model group of 14 days, mainly lipid metabolites, which were mainly involved in oxidative damage and inflammatory process. A total of 34 differential metabolites, mainly amino acid metabolites, were screened between the control group and model group, mainly involving nucleic acid damage and inflammatory process. Compared with the model group, the HYP content, fibrosis score and alveolitis score in the lung tissue of mice from high-dose WHG group decreased significantly(P<0.05, P<0.01), and the total number of lymphocytes in BALF decreased significantly(P<0.05). Compared with the model group, 27, 40 differential metabolites were identified in the serum of mice from the low-dose WHG group and high-dose WHG group separately. There were totally 9 common differential metabolites between the model group and low-dose WHG group/high-dose WHG group, which mainly involved in the metabolic pathways of inflammation related lipids metabolism, arginine and tryptophan metabolism, and the change trends in low-dose WHG group and high-dose WHG group were significantly back-regulated compared with the model group. ConclusionWHG can alleviate BLM-induced pulmonary fibrosis, collagen deposition and inflammatory reaction in mice, and its anti-fibrotic effect may be related to the adjusting of inflammatory factors, nitric oxide and oxidative stress related metabolic pathways.

RESUMEN

ObjectiveTo investigate the intervention effect of Qufeng Gutong Babu ointment (QFGT) on rats with osteoarthritis (OA) with cold-dampness obstruction, and preliminarily clarify its mechanism. MethodSD male rats were divided into 6 groups, namely, the blank group, model group, positive control drug Huoxue Zhitong ointment (HXZTG) group (1.26 cm2·d-1), and low, medium, and high-dose QFGT group (75, 150, 300 mg·d-1). OA model was prepared by joint cavity injection of papain and L-cysteine. On the second day of modeling, climate factors were applied to establish an animal model of combination of disease and syndrome of OA rats with cold-dampness obstruction. Standard VonFrey fiber was used to evaluate the threshold of mechanical pain. Weight bearing difference score and joint function score of both hind limbs were recorded. Hematoxylin-eosin (HE) staining and safranine fixation green staining were used to observe the pathological changes and cartilage degeneration of rat knee joint. Immunohistochemistry (IHC) was used to detect the expression of interleukin-1β (IL-1β), interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α), matrix metalloproteinase-9 (MMP-9), and cathepsin K (CTSK). Western blot was used to detect the protein expression of kinase B (Akt), phosphorylated protein kinase B (p-Akt), phosphatidylinositol 3-kinase (PI3K), nuclear factor 1 (NFATc1), MMP-9, and CTSK in T cells. ResultCompared with the normal group, the model group showed significant mechanical pain sensitivity reaction after modeling (P<0.01), and the weight bearing difference of both hind limbs and joint function score were significantly increased (P<0.05, P<0.01). Compared with the model group, both the high-dose QFGT group and the HXZTG group significantly reduced the mechanical pain sensitivity, weight difference, and joint function score of rats (P<0.05, P<0.01), and the medium-dose QFGT group also improved the joint function to a certain extent, and the degeneration of the knee joint cartilage of rats was significantly reduced (P<0.05, P<0.01). QFGT and HXZTG both inhibited the protein expression of IL-1β, IL-8, TNF-α, MMP-9, CTAK, PI3K, p-Akt, Akt, and other related proteins in articular cartilage of rats with OA to a certain extent (P<0.05, P<0.01). ConclusionQFGT can inhibit the release of inflammatory factors and matrix metalloproteinases by inhibiting the PI3K/Akt signal pathway in articular articular cartilage of rats with OA with cold-dampness obstruction, thus ultimately weakening local cartilage degeneration and improving joint function.

RESUMEN

OBJECTIVE To study the anti-inflammatory effect and mechanism of the ethanol extract and the drug-containing serum of Zhuang medicine Stahlianthus involucratus on lipopolysaccharide (LPS)-induced RAW264.7 cell inflammation. METHODS The drug-containing serum or blank serum was obtained by intragastrical administration of ethanol extract of S. involucratus (75.35 g/kg) or purified water. Using RAW264.7 cells as objects, RAW264.7 cells were divided into normal control group, LPS group (1 μg/mL), S. involucratus ethanol extract high-dose, medium-dose and low-dose groups (50, 25, 12.5 μg/mL), 4% or 15% blank serum groups, 4% or 15% blank serum+LPS groups, 4% or 15% drug-containing serum groups, 4% or 15% drug-containing serum+LPS groups. After culturing for 24 h, cell viability, the contents of nitric oxide tumor necrosis factor α (TNF-α), interleukinand IL-6 as well as mRNA expressions of Toll-like eceptor 4 (TLR4) and nuclear factor κB (NF- κB) and protein expressions of nitric oxide synthase (NOS) and cyclooxygenase 2 (COX-2) were all detected in each group. 0771-4953513。E-mail:zhuhuagx@163.com RESULTS After culturing for 24 h, there was no statisticalsignificance in the difference of cell viability. Compared with normal control group, the contents of NO, TNF-α, IL-1β and IL-6, mRNA expressions of TLR4 and NF-κB, and protein expressions of NOS and COX-2 were increased significantly in LPS group (P<0.05). Compared with 4% or 15% blank serum groups, the levels of above indexes were increased significantly in 4% or 15% blank serum+LPS groups (P<0.05). Compared with LPS group, the levels of above indexes were decreased significantly in S. involucratus ethanol extract groups (P<0.05). Compared with 4% or 15% blank serum+LPS groups, the levels of above indexes were decreased significantly in 4% or 15% drug-containing serum+LPS groups (P<0.05). CONCLUSIONS The ethanol extract and the drug-containing serum of S. involucratus can significantly alleviate LPS-induced inflammatory reaction, the mechanism of which may be associated with inhibiting the activity of TLR4/NF-κB signaling pathway, down-regulating the protein expressions of COX-2 and NOS, and reducing the release of inflammatory factors.

RESUMEN

ObjectiveTo investigate the effects of different acupuncture schemes on behaviors, neurotransmitters and inflammation-related factors in post-stroke depressed (PSD) rats. MethodsA total of 72 healthy male Sprague-Dawley rats were randomly divided into normal group, model group, drug control group, scalp acupuncture group, abdominal acupuncture group and combined acupuncture group, 12 rats in each group. The PSD model was prepared using a combination of middle cerebral artery occlusion and chronic unpredictable mild stimulation (CUMS) for the model and each intervention groups. The drug control group was administered fluoxetine, the scalp acupuncture group accepted acupuncture at Baihui (DU 20) and Yintang (EX-HN3), while the abdominal acupuncture group at Zhongwan (RN 12) and Guanyuan (RN 4), the combined acupuncture group at all the four acupoints, for 21 days. They were assessed with Longa neurological function score, body mass, open-field test and sugar-water preference test on the 0 (before modeling), the seventh (before CUMS), the 14th (before treatment) and the 35th day (after treatment). The levels of 5-hydroxytryptamine (5-HT), dopamine (DA), norepinephrine (NE), interferon-γ (INF-γ), tumor necrosis factor⁃α (TNF⁃α) and macrophage migration inhibitory factor (MIF) in the serum were determined with ELISA on the 35th day. Results The neurological function score was lower in the drug control group and the combined acupuncture group thanin the model group (P < 0.01) on the 35th day; while the body mass was higher in the drug control group, the abdominal acupuncture group and the combined acupuncture group than in the model group (P < 0.01); and the number of horizontal span frames, the number of uprightness and the sugar water consumption were higher in the drug control group, the scalp acupuncture group, the abdominal acupuncture group and the combined acupuncture group than in the model group (P < 0.05). There was no significant difference among the four intervention groups (P > 0.05). The levels of 5-HT, DA and NE were higher in the four intervention groups than in the model group (P < 0.01), and the levels of IFN-γ, TNF⁃α and MIF were lower (P < 0.01). 5-HT level was higher in the combined acupuncture group than in the scalp acupuncture group and the abdominal acupuncture group, and the levels of IFN-γ, TNF⁃α and MIF were lower (P < 0.01); the levels of DA and NE was higher in the combined acupuncture group than in the abdominal acupuncture group (P < 0.01). ConclusionThe combination of scalp acupuncture and abdominal acupuncture can improve behavior, neurotransmitters and inflammatory factors of PSD rats, like fluoxetine. Scalp or abdominal acupuncture alone is still effecive, and can be used secondarily.
