Hepatic and skeletal muscle tissue immunometabolism in trained rats / Inmunometabolismo del tejido hepático y muscular esquelético de ratas entrenadas / Imunometabolismo tecidual hepático e muscular esquelético de ratos treinados

ABSTRACT Introduction: Physical exercise can be an alternative for preventing and treating the harmful effects of obesity, mainly inflammatory effects on skeletal muscle and liver tissues. However, no consensus exists regarding this purpose's best physical training model. Objective: Evaluate morphological, metabolic, and inflammatory alterations in rats' skeletal and hepatic muscle tissues caused by aerobic and resistance training. Methods: 24 Wistar rats were divided into sedentary (S), aerobic (AE), and resistance training (R) groups. Blood glucose, total cholesterol, and serum triglycerides were measured periodically. After euthanasia, body mass was measured to calculate the total mass gain during the experiment. High-density lipoprotein (HDL) was measured. Adipose tissue was extracted to calculate its percentage relative to body mass and the liver, soleus, and gastrocnemius muscles for morphological analyses and concentrations of glycogen, lipids, and Tumor Necrosis Factor α (TNF-α). The Kruskall-Wallis test and Dunn's post-test were performed for statistical analysis, adopting p<0.05. Results: Both training models reduced the percentage of adipose tissue, body mass gain, and hepatic TNF-α concentration (p<0.05). AE increased serum HDL, gastrocnemius fiber diameter and reduced the fractal dimension in the soleus (p<0.05). R reduced blood glucose and serum and liver lipids, increased liver and soleus glycogen concentrations, increased gastrocnemius fiber diameter, and decreased TNF-α (p<0.05). Conclusion: Both training models reduced body mass, relative visceral adipose tissue, serum total cholesterol concentration, and liver inflammation. However, resistance training was more effective in promoting metabolic effects in the liver and skeletal muscle and reducing muscle inflammation in rats. Level of Evidence V; Expert Opinion.

RESUMEN Introducción: El ejercicio físico puede ser una alternativa para prevenir y tratar los efectos nocivos de la obesidad, principalmente los efectos inflamatorios sobre los tejidos del músculo esquelético y del hígado. Sin embargo, no existe consenso sobre cuál es el mejor modelo de entrenamiento físico para este fin. Objetivo: Evaluar las alteraciones morfológicas, metabólicas e inflamatorias del entrenamiento aeróbico y de resistencia en sobre los tejidos músculo esqueléticos y hepáticos de ratas. Métodos: 24 ratas Wistar se dividieron en grupos sedentarios (S), aeróbicos (AE) y de entrenamiento de resistencia (R). Se midieron periódicamente glucosa en sangre, colesterol total y triglicéridos. Después de la eutanasia, se midió la masa corporal para calcular la ganancia de masa total durante el experimento. Se midió la lipoproteína de alta densidad (HDL). Se extrajo tejido adiposo para calcular su porcentaje relativo a la masa corporal, así como hígado, músculos sóleo y gastrocnemio para análisis morfológicos y concentraciones de glucógeno, lípidos y Factor de Necrosis Tumoral α (TNF-α). Para el análisis estadístico fueron utilizados Kruskall-Wallis y el post-test de Dunn, adoptando p<0,05. Resultados: Ambos entrenamientos redujeron el porcentaje de tejido adiposo, masa corporal y la concentración de TNF-α hepático (p<0,05). AE aumentó el HDL sérico, el diámetro de la fibra del gastrocnemio y redujo la dimensión fractal en el sóleo (p<0,05). R redujo la glucosa en sangre y los lípidos séricos y hepáticos, aumentó las concentraciones de glucógeno hepático y sóleo, aumentó el diámetro de la fibra del gastrocnemio y disminuyó el TNF-α (p<0,05). Conclusión: Ambos modelos de entrenamiento redujeron la masa corporal, el tejido adiposo visceral relativo, la concentración sérica de colesterol total y la inflamación hepática.

RESUMO Introdução: O exercício físico pode se apresentar como uma alternativa para prevenção e tratamento de efeitos deletérios da obesidade, principalmente efeitos inflamatórios sobre os tecidos muscular esquelético e hepático. No entanto, não há consenso quanto ao melhor modelo de treinamento físico para tal finalidade. Objetivos: Avaliar alterações morfológicas, metabólicas e inflamatórias dos treinamentos aeróbico e resistido sobre os tecidos muscular esquelético e hepático de ratos. Métodos: 24 ratos Wistar foram divididos nos grupos sedentário (S), treinamento aeróbico (AE) e resistido (R). Glicemia, colesterol total e triglicerídeos séricos foram mensurados periodicamente. Após a eutanásia, a massa corporal foi mensurada para calcular o ganho total de massa durante o experimento. A lipoproteína de alta densidade (HDL) foi dosada. O tecido adiposo foi extraído para cálculo de sua porcentagem relativa à massa corporal assim como o fígado e os músculos sóleo e gastrocnêmio para as análises morfológicas e das concentrações de glicogênio, lipídios e Fator de Necrose Tumoral α (TNF-α). Para análise estatística, foram utilizados o teste de Kruskall-Wallis e o pós-teste de Dunn, adotando-se p<0,05. Resultados: Ambos os modelos de treinamento reduziram o percentual de tecido adiposo, ganho de massa corporal e concentração hepática de TNF-α (p<0,05). AE aumentou o HDL sérico, o diâmetro das fibras do gastrocnêmio e reduziu a dimensão fractal no sóleo (p<0,05). R reduziu a glicemia e os lipídios séricos e hepáticos, aumentou a concentração de glicogênio hepático e sóleo, aumentou o diâmetro das fibras gastrocnêmicas e diminuiu o TNF-α (p<0,05). Conclusão: Ambos os modelos de treinamento reduziram a massa corporal, o tecido adiposo visceral relativo, a concentração sérica de colesterol total e a inflamação hepática. No entanto, o treinamento resistido mostrou-se mais eficaz em promover efeitos metabólicos no fígado e no músculo esquelético, além de reduzir a inflamação muscular em ratos.

New immunological aspects of peri-implantitis

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.

Development and verification of a rapid detection method for adalimumab biological activity based on U937-NF-κB-Luc cell line / 中国生物制品学杂志

@#Objective To develop and verify a rapid detection method for the biological activity of adalimumab based on U937-NF-κB-Luc cell line. Methods Using U937-NF-κB-Luc cell line as the detection cells,a method for detecting the biological activity of adalimumab was developed based on luciferase luminescence principle. The method was optimized for the concentration of tumor necrosis factor-α(TNF-α)(160 ng/mL as initial concentration,2 times serial dilution,10dilutions),the initial concentration of antibody(2 000 ng/mL,2 times serial dilution,20 dilutions),the dilution multiple of antibody(1. 5,2,3,4 times),the inoculation amount(8 × 103,2 × 104,4 × 104,6 × 104cells/well)and the incubation time(0. 5,1,2,3 h),and verified for the specificity,accuracy,precision and linear range. The relative potency of five batches of adalimumab was detected by using the optimized method and TNF-α neutralization activity method based on L929cells respectively. Results The dose-response curve of adalimumab international standard showed a typical S-type,and the data complied with the four-parameter equation y =(A-D)/[1 +(x/C)B]+ D,R2> 0. 99. The optimum concentration of TNF-α was 5 ng/mL,the initial concentration of antibody was 800 ng/mL,the dilution ratio for adalimumab was 1∶2,the inoculation amount was 2 × 104cells/well,and the induction time was 2 h. Three therapeutic monoclonal antibodies of TNF-α target,such as adalimumab,obtained good dose-response curves,while therapeutic monoclonal antibodies of other non-TNF-α targets did not show this curve. The linear regression equation of the logarithmic value of theoretical potency and the logarithmic value of the corresponding measured potency had a slope of 1. 037,and the relative bias was within the range of ± 12%. The geometric coefficient of variation(GCV)of the relative titer measured value of each sample was less than20%. The theoretical potency ranged from 64% to 156%,showing a good linear relationship with the measured values,and the fitting linear regression equation was y = 1. 037 4 x-0. 023 7,R2= 0. 998 4. There was no significant difference in the relative potency measured results of five batches of adalimumab by the two methods(t = 1. 198,P = 0. 265 1). Conclusion The developed detection method for adalimumab biological activity based on U937-NF-κB-Luc cell line has good specificity,accuracy and precision with short time consumption(3 h),which can be used as a rapid evaluation method for the biological activity of adalimumab.

Research progress of adipokines and diabetic retinopathy / 国际眼科杂志(Guoji Yanke Zazhi)

Diabetic retinopathy(DR)is one of the common microangiopathy in diabetes and the main cause of blindness in adults. It can be seen that it is very important to find the specific target of DR prevention and treatment. Adipose tissue is not only an energy storage tissue, but also an active endocrine organ, which can release a variety of cytokines, called adipokines. Studies have shown that adipokines play an important role in the occurrence and development of DR. Adipokines can not only directly act on vascular endothelium through blood circulation, but also indirectly affect vascular endothelial function by affecting the activity of sympathetic nervous system and insulin sensitivity, which leads to dysfunction of vascular endothelial cells, increased retinal vascular permeability, neurodegeneration and neovascularization, and finally leads to the destruction of blood-retinal barrier. In recent years, the role of some new adipokines in DR has been paid more and more attention. This paper reviews the related research of several new adipokines in DR.

Study of Three Potential Diagnostic Biomarkers in Nasopharyngeal Carcinoma Samples from Guilan, North of Iran

Abstract Introduction Finding biomarkers for highly lethal cancers is a priority. Objective The current study was designed to understand the clinical significance of vascular endothelial growth factor (VEGF), latent membrane protein 1 (LMP1), and tumor necrosis factor-α (TNF-α) expression as the biomarkers, and evaluate their correlation with each other, in nasopharyngeal carcinoma (NPC) in the province of Guilan, North of Iran. Methods Gene expression was evaluated in 25 formalin-fixed paraffin-embedded (FFPE) blocks from cases of confirmed NPC and 20 FFPE samples of non-NPC by quantifying messenger ribonucleic acid (mRNA) and protein levels, using real-time polymerase chain reaction (PCR) and immunohistochemistry (IHC) methods, respectively. Furthermore, the correlations among the protein levels of different genes, along with the patients' demographic characteristics were assessed. Results Our findings on mRNA and protein levels demonstrated that the expression of the LMP1 gene in the NPC group was significantly elevated compared with that of the non-NPC group. In addition, the protein levels in the NPC group indicated a positive and significant correlation between LMP1 and VEGF expression. It was noted that both protein and mRNA levels showed no significant differences in the expression of TNF-α and VEGF genes between the NPC and control groups. Furthermore, there was no significant relationship between the expression of these proteins and the demographic characteristics of NPC patients. Conclusion Overall, a significant increase in LMP1 expression was observed in NPC patients, which may serve as a diagnostic biomarker for NPC. Also, LMP1 might be involved in NPC progression by inducing VEGF gene expression.

The prognostic values of the IL?10 (G1082A) and TNF?? (G308A) polymorphisms in Egyptian patients with acute lymphoblastic leukemia: A single?center study

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.

Oral lichen planus in a young patient: a case report with nine-year follow-up / Líquen plano oral em paciente jovem: um relato de caso com acompanhamento de nove anos

INTRODUCTION: Oral lichen planus is an inflammatory condition that affects the stratified squamous epithelium of the oral mucosa. It occurs more frequently in female patients and it is rarely observed in children, adolescents, or young adults. This study aims to report a case of oral lichen planus in a young patient with a nine-year followup. CASE REPORT: A 19-year-old man reported to the Dentistry Department with a complaint of an asymptomatic white lesion on the dorsum and left lateral border of his tongue, which had appeared a few weeks before. Two weeks later, a second lesion, very similar to the previous one, appeared on the central region of his tongue. An incisional biopsy was performed. The histological slides were stained with hematoxylin-eosin and the expression of interleukin-1beta (IL-1ß) and tumor necrosis factor-alpha (TNF-α) was assessed by immunohistochemistry. No pharmacological treatment was prescribed. The clinical and histopathological findings were suggestive of oral lichen planus. The IL-1ß/TNF-α expression was low. There was a spontaneous regression of the lesions after approximately one year. The nine-year follow-up showed no signs of recurrence. CONCLUSION: This case presents atypical features such as the age of the patient and the spontaneous remission of the lesions.

INTRODUÇÃO: O líquen plano oral é uma condição inflamatória que acomete o epitélio escamoso estratificado da mucosa oral. Ocorre mais frequentemente em pacientes do gênero feminino e é raramente encontrado em pacientes pediátricos ou juvenis. O objetivo do presente estudo é relatar um caso de líquen plano oral em um paciente jovem com acompanhamento de nove anos. RELATO DE CASO: Um rapaz de 19 anos procurou atendimento no Departamento de Odontologia com a queixa de uma lesão branca assintomática em região de dorso e borda lateral esquerda de sua língua, com tempo de evolução de algumas semanas. Duas semanas depois, uma segunda lesão, muito similar à primeira, apareceu na região central de sua língua. Uma biópsia incisional foi realizada. As lâminas histológicas foram coradas com hematoxilina-eosina e a expressão de interleucina-1beta (IL-1ß) e de fator de necrose tumoral alfa (TNF-α) foram avaliadas por imunohistoquímica. Nenhum tratamento farmacológico foi prescrito. Os achados clínicos e histopatológicos foram sugestivos de líquen plano oral. A expressão de IL-1ß/TNF-α foi baixa. Houve uma regressão espontânea das lesões após aproximadamente um ano. O acompanhamento de nove anos não detectou sinais de recorrência. CONCLUSÃO: Esse caso apresenta características atípicas, como a idade do paciente e a remissão espontânea das lesões.

Biocompatibility of the Oxygenator on Pulsatile Flow by Electron Microscope

ABSTRACT Introduction: Extracorporeal perfusion flow type requires further investigation. The aim of this study is to compare the effects of pulsatile and nonpulsatile flow on oxygenator fibers that were analyzed by scanning electron microscope (SEM) and to extensively study patients' coagulation profiles, inflammatory markers, and functional blood tests. Methods: Twelve patients who had open heart surgery were randomly divided into two groups; the nonpulsatile flow (group NP, six patients) and pulsatile flow (group P, six patients) groups. Both superficial view and axial sections of the oxygenator fiber samples were examined under SEM to compare the thickness of absorbed blood proteins and amount of blood cells on the surface of oxygenators. Platelet count, coagulation profile, and inflammatory predictors were also studied from the blood samples. Results: Fibrinogen levels after cardiopulmonary bypass were significantly lower in group NP (group P, 2.57±2.78 g/L; group NP; 2.39±0.70 g/L, P=0.03). Inflammatory biomarkers such as C-reactive protein, interleukin (IL)-6, IL-12, apelin, S100β, and tumor necrosis factor alpha were comparable in both groups. Axial sections of the oxygenator fiber samples had a mean thickness of 45.2 µm and 46.5 µm in groups P and NP, respectively, and this difference is statistically significant (P=0.006). Superficial view of the fiber samples showed obviously lower platelet, leukocyte, and erythrocyte levels in group P. Conclusion: Our study demonstrated that both cellular elements and protein adsorption on oxygenator fibers are lower in the group P than in the group NP. Pulsatile perfusion has better biocompatibility on extracorporeal circulation when analyzed by SEM technique.

Anti-inflammatory and antioxidant potential of Artemisia dracunculus L. aqueousextract against acetic acid induced ulcerative colitis in male Wistar rats

Ulcerative colitis (UC) is one of the two types of inflammatory bowel disease (IBD) which is increasing worldover due to modern life style. Patients with UC are prone to develop colorectal cancer. While the disease severity decides the treatment option, researchers look towards herbal medicines with anti-inflammatory properties for minimal or nil side effects. Artemisia dracunculus L., commonly called Tarragon, is a medicinal herb used in traditional Asian medicine mainly in Iran, India, Pakistan and Azerbaijan due to its special compounds. In this study, we tried to elucidate the effects of aqueous extract of tarragon on acetic acid induced ulcerative colitis (UC) in rats. Male Wistar rats were grouped into four groups of eight each viz., control; experimental control (UC was induced via luminal instillation of 4% acetic acid); and UC induced + aqueous tarragon extract (100 mg/kg) or prednisolone (2 mg/kg) orally for ten consecutive days. Tissue specimens were collected after the experimental period for evaluation of caspase-3 and cyclooxygenase-2 (COX-2) expression by immunohistochemistry. Real-time PCR was used to monitor the levels of IL-1, IL-6 and TNF-? in colonic homogenates. Moreover, the levels of myeloperoxidase, nitric oxide and total antioxidant capacity were measured in colonic homogenates. The results showed that both treatment regimens could similarly reduce the severity of disease symptoms. Treatment with aqueous extract of tarragon caused a better improvement (P <0.05) in the levels of myeloperoxidase enzyme, and total antioxidant capacity of colonic homogenates compared to prednisolone. Nevertheless, the levels of the expression of caspase-3, and COX-2 and TNF-? were reduced in UC rats received prednisolone more than UC rats received aqueous extract of tarragon. The was no statistical difference in the levels of nitric oxide, IL-1 and IL-6 between UC rats received tarragon extract or prednisolone. Overall, these findings suggest that the aqueous extract of tarragon is a promising strategy to control ulcerative colitis. Aqueous extract can also be used as an anti-inflammatory and immune system stimulant in conditions where the immune system is damaged.

Correlation analysis of serum zonulin, ZO-1, TNF-α with severity of acute pancreatitis / 中国医师杂志

Objective:To analyze the correlation between the severity of acute pancreatitis (AP) and the levels of zonulin, zonula occludens protein-1 (ZO-1), tumor necrosis factor -α (TNF -α) in the peripheral blood of patients with acute pancreatitis (AP), and the value of predicting moderate and severe AP.Methods:The clinical data of 115 AP patients admitted to the Second Affiliated Hospital of Anhui Medical University from June 2020 to January 2022 were retrospectively analyzed. They were divided into mild group (69 cases) and moderate severe group (46 cases). The blood levels of zonulin, ZO-1, and TNF-α were measured for all patients on the 1st, 3rd, and 7th day after admission, and the results of the two group tests were compared. The correlation between zonulin, ZO-1, TNF -α and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) scores on the 1st day was and the value of various indicators for predicting moderate to severe AP were analyzed.Results:The C-reactive protein (CRP) levels of AP patients in the moderate to severe group were higher than those in the mild group, and the difference was statistically significant (all P<0.05). The levels of zonulin, ZO-1, and TNF -α in AP patients in the moderate to severe group showed an upward trend on the 1st, 3rd, and 7th days after admission. The levels of zonulin, ZO-1, and TNF -α in AP patients in the moderate to severe group were higher than those in the mild group at the same time point, and the differences were statistically significant (all P<0.05). The APACHE Ⅱ score of AP patients on the first day of admission was positively correlated with the levels of zonulin, ZO-1, and TNF -α ( r=0.736, 0.552, 0.621, all P<0.05). Zonulin had the highest area under the curve (AUC) for predicting moderate to severe AP, at 0.892, with an optimal threshold of 2.075 pg/ml. Zonulin had the highest sensitivity, at 0.804, and ZO-1 had the highest specificity, at 0.926. Using zonulin ≥2.075 pg/ml, ZO-1≥399.4 ng/ml, and TNF -α≥40.88 pg/ml as thresholds; the sensitivity and specificity obtained from parallel experiments were 0.976 and 0.710, respectively; The sensitivity and specificity obtained from the series of experiments were 0.326 and 0.999, respectively. Conclusions:There is a correlation between the serum levels of zonulin, ZO-1, and TNF -α in AP patients and the severity of AP. Zonulin, ZO-1, and TNF -α have certain clinical value in predicting moderate to severe AP.

Effects of thoracic segment epidural anesthesia on inflammatory factors in patients undergoing lung cancer surgery / 中国基层医药

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.

Effects of butylphthalide combined with alteplase on acute ischemic stroke / 中国基层医药

Objective:To analyze the effects of butylphthalide combined with alteplase on acute ischemic stroke.Methods:A total of 176 patients with acute ischemic stroke who received treatment at The Second People's Hospital of Liaocheng from November 2020 to October 2021 were prospectively included in this study. They were divided into control and combined treatment groups ( n = 88/group) according to hospital registraction number. The control group was given intravenous thrombolysis with alteplase. The combined treatment group was intravenously administered alteplase for 6 hours followed by butylphthalide sodium chloride injection. The two groups were treated for 2 consecutive weeks. The National Institutes of Health Stroke Scale score, clinical efficacy, interleukin-6, tumor necrosis factor-α, and high-sensitivity C-reactive protein levels as well as the incidence of adverse drug reactions were compared between the two groups. Results:After thrombolysis, the National Institutes of Health Stroke Scale score, interleukin-6, tumor necrosis factor-α, and high-sensitivity C-reactive protein levels in the combined treatment group were (4.23 ± 1.75) points, (6.42 ± 2.05) ng/L, (13.42 ± 3.59) ng/L, and (3.17 ± 0.94) mg/L, respectively, which were significantly lower than (7.28 ± 1.93) points, (9.58 ± 2.79) ng/L, (22.28 ± 3.73) ng/L, and (5.23 ± 1.25) mg/L, respectively in the control group ( t = 10.98, 20.29, 16.06, 12.36, all P < 0.001).

Value of serum interleukin-6 and tumor necrosis factor-α in early diagnosis of severe acute pancreatitis / 临床肝胆病杂志

Objective To investigate the value of serum cytokines in the early diagnosis of severe acute pancreatitis (SAP), and to improve the accuracy of the diagnosis of SAP by establishing a mathematical model with composite indices based on LASSO algorithm. Methods A total of 130 patients with acute pancreatitis (AP) who attended Changshu First People's Hospital from January 2019 to June 2022 were enrolled, among whom there were 73 SAP patients and 57 non-SAP patients.Peripheral serum samples were collected from all patients, and Luminex xMAP liquid chip technique was used to measure 13 serum cytokines.Meanwhile, Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ), Bedside Index for Severity in Acute Pancreatitis (BISAP), and Computed Tomography Severity Index (CTSI) scores were determined for all patients.The Kolmogorov-Smirnov method was used for normality test; the independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups.Furthermore, the binary logistic regression analysis was used to evaluate the effect of cytokines on SAP, and the linear regression analysis was used to investigate the correlation between cytokines and SAP severity.The partial correlation analysis was used to evaluate the correlation between cytokines and SAP severity score after adjustment for covariates[age, sex, body mass index (BMI), and history of hypertension and diabetes].The LASSO algorithm was used to establish a mathematical model with composite indices; the receiver operating characteristic (ROC) curve was used to assess the performance of serum cytokines in the clinical diagnosis of SAP, and the area under the ROC curve (AUC) was calculated. Results Compared with the SAP group, the non-SAP group had significantly lower APACHE Ⅱ, BISAP, CTSI, and modified Marshall scores (all P < 0.001).Compared with the non-SAP group, the SAP group had significantly higher levels of interferon-γ(IFN-γ), interleukin-6(IL-6), interleukin-8, and tumor necrosis factor-α(TNF-α) and a significantly lower level of interleukin-12(all P < 0.05).The logistic regression analysis showed that IFN-γ(odds ratio[ OR ]=1.190, 95% confidence interval[ CI ]: 1.036-1.367, P =0.014), IL-6 ( OR =1.148, 95% CI : 1.070-1.231, P < 0.001), and TNF-α ( OR =1.100, 95% CI : 1.048-1.155, P < 0.001) were independent influencing factors for SAP.The partial correlation analysis showed that after adjustment for sex, age, BMI, and history of chronic diseases (diabetes and hypertension), the levels of IL-6 and TNF-α were positively correlated with APACHE Ⅱ score in SAP patients (IL-6: r =0.503, P < 0.001;TNF-α: r =0.557, P < 0.001).The linear regression analysis showed that the levels of IL-6 and TNF-α were associated with APACHE Ⅱ score in SAP patients (IL-6: β =0.049, P =0.044;TNF-α: β =0.054, P =0.046), and there was an interaction between IL-6 and TNF-α, which affected APACHE Ⅱ score.The ROC curve analysis showed that the risk score based on IL-6 and TNF-α using LASSO algorithm had the largest AUC of 0.925 in distinguishing SAP from non-SAP, while IL-6 or TNF-α alone had an AUC of 0.885 and 0.878, respectively.The partial correlation analysis showed that after adjustment for sex, age, BMI, and history of chronic diseases (diabetes and hypertension), the risk score was positively correlated with APACHE Ⅱ score in SAP patients ( r =0.565, P < 0.001). Conclusion The serum levels of IL-6 and TNF-α can reflect the severity of AP.The risk score combining serum IL-6 and TNF-α can significantly improve the accuracy of the early diagnosis of SAP, which has an important clinical value in the clinical diagnosis and treatment of SAP.
