Goal of this study was to evaluate effects of Mao-to on development of myocarditis induced by encephalomyocarditis (EMC) virus in mice. Mice were randomly divided into five groups. Group N included uninfected controls (n= 18), while group A, B and C underwent intraperitoneal injection of EMC virus. Group A was administered oral saline from day 0 to day 4. Group B was administered oral Mao-to (500 mg−1kg−1day−1) from day 0 to day 4. Group C was administered Mao-to from day 2 to day 6. Group D was administered Mao-to from day 5 to day 10. Treated mice were followed for survival rates during 2 weeks after infection. Body weight (BW) and organ weights including heart (HW), lungs, thymus and spleen were examined on days 4, 6 and 14. Survival rate of group C (36.4%) was significantly improved compared with group A, B or D (0% of each,P< 0.05). HW and HW/BW ratio in group C was significantly (P< 0.05) lower than those in group A, B or D. Viral titers of hearts were significantly different among groups A, B and C. Cardiac expression in tumor necrosis factor-α (TNF-α) was significantly reduced in group C in comparison with group A, B or D on day 6 by immunohistochemical study. Administration of Mao-to starting on day 2 improves mortality resulting from viral myocarditis in mice with reduced expression of cardiac TNF-α. These findings suggest that timing of Mao-to is crucial for preventing cardiac damage in mice with viral myocarditis.

Objective.To assess the association between treatment with anti-tumor necrosis factor-α (TNF-α) agents and the occurrence of hospitalizations, their causes and complications, compared to treatment with traditional disease-modifying antirheumatic drugs in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS).Methods.A retrospective cohort study was conducted of patients with RA, AS, and PsA treated with anti-TNF-α agents between April 2002 and December 2007. Patients were assessed during the period of anti-TNF-α treatment (Group B) and compared to an equivalent period before initiation of anti-TNF-α therapy (Group A). All hospitalization charts were reviewed and diagnoses, comorbidities, concomitant medications, and clinical course were analyzed. Statistical analysis was performed using multivariate mixed Poisson regression.Results.In the study period of 57 months, 735 hospitalization events of 327 patients were analyzed. Statistically significant decreases were seen in the total number of hospitalization events as well as hospitalizations due to exacerbation of rheumatic diseases in Group B compared to Group A (44.4 vs 74.2 and 21.9 vs 47.5 per 100 patient-years, respectively; p < 0.0001). More infectious events (7.4 in Group B compared to 4.6 per 100 patient-years in Group A; p = 0.043) were associated with anti-TNF-α treatment, older age, and underlying disease, because patients with RA had higher rates of infections compared to patients with PsA and patients with AS.Conclusion.The overall effect of anti-TNF-α therapy was a significant decline in total hospitalization events. The decrease was more prominent in patients with RA than in patients with AS and patients with PsA, and reflected the significant decrease in hospitalizations due to rheumatic disease exacerbation. The decrease was more pronounced than the observed increase in infectious events.

Tumour necrosis factor-α (TNF-α) is considered to be involved in the insulin resistance of type 2 diabetes mellitus. The offspring of patients with type 2 diabetes mellitus are at increased risk of developing diabetes and several metabolic abnormalities, but the underlying defects responsible are not known. We studied serum TNF-α levels in 30 healthy non-diabetic offspring of type 2 diabetic parents (group A), and the relationship between TNF-α levels and variables associated with insulin resistance and diabetes. For comparison, 30 healthy offspring of non-diabetic parents (group B) were also studied. The median serum concentration of TNF-α was significantly higher in group A than in group B, 3.5 pg/ml compared with 2.0 pg/ml, respectively. The individuals of group A also had significantly elevated levels of glycosylated haemoglobin, fasting glucose, glucose 2 h after an oral glucose tolerance test and triglycerides. We conclude that serum TNF-α concentration is significantly elevated in non-diabetic offspring of type 2 diabetics and this may predict later impairment of insulin action in these individuals.

Cytroreductive surgery (CRS) and HIPEC are controversial effective treatment options for selected patients with peritoneal metastases. We retrospectively examined 4.500 patients with peritoneal metastases from different tumors from 2005 to 2020. Patients were divided in 4 groups, surgery plus HIPEC and then systemic chemotherapy: Group A n=730, Group B n=700, R0 surgery plus systemic chemotherapy, Group C n=870, palliative surgery plus systemic chemotherapy and Group D n=2.200, palliative care and best support. The postoperative outcomes, morbidity, mortality were compared between the 4 groups. The mean survival rates Group A=24,4+10,2m, Group B= 18,4+6,3m, Group C=12,3+5,7m, Group D=5,8+2,3m (p<0.05 between Gr A vr Gr B). There was no statistically significant difference in the 30-day mortality and morbidity. In conclusion CRS + HIPEC are feasible in 16% of our patients with peritoneal metastases and are associated with pro-longed survival.

Abstract Objective: to observe the effects of moxibustion on histomorphological changes of gastric mucosa, as well as on serum IL-6、IL-8、TNF-α，Hp IgG、CD3+、CD4+、CD8+ in helicobacter pylori (Hp) infected rats, so that to better understand how the moxibustion repairs the Hp- induced gastric mucosal injury. Methods: 40 SD rats were randomly assigned to four groups: group A (blank control), group B (Hp infection model), group C (moxibustion plus model), group D (electro-acupuncture plus model), 10 for each group. The “NaHCO3 plus Indometacin and Hp intragastric administration” method was employed to make gastritis model. Acupoints selected for “repair” purpose were Zu San Li (ST36), Zhong Wan (CV12), Guan Yuan (RN4), Pi Shu (BL20), Wei Shu(BL21). The histomorphological changes of gastric mucosa in rats were observed under light microscope after HE stain; IL-6, IL-8, TNF-α, Hp IgG values were evaluated by ELISA method; values of CD3+、CD4+、CD8+、CD4+/CD8+ were measured by flow cytometry method. Results: compared with group A, the values of IL-6, IL-8, TNF-α, Hp IgG and CD8+ in group B were increased（P＜0.01）, whereas the values of CD3+、CD4+、CD4+/CD8+ were decreased（P＜0.01）. Compared with group B, the values of IL-8（P＜0.05）,TNF-α（P＜0.05）, IL-6（P＜0.01）, Hp IgG（P＜0.01） and CD8+ （P＜0.05） in group C were decreased, whereas the values of CD3+（P＜0.05）,CD4+（P＜0.05）,CD4+/CD8+ （P＜0.05） were increased, meanwhile such values in group D had no significant changes. Compared with group D, the values of IL-6（P＜0.05）,IL-8 （P＜0.05）and Hp IgG （P＜0.01）in group C were decreased, whereas CD4+/CD8+（P＜0.05）were increased, all those changes had statistical significance. Conclusion: the preventive and therapeutic effects of moxibustion on Hp related gastritis might be realized by two ways- to inhibit the secretion of proinflammatory cytokines such as IL-6, IL-8 and TNF-α, or to regulate the production of immune factors (such as up-regulation of CD3+, CD4+ and down-regulation of CD8+).

Background: Objective of the study was to provide insight on the immune response in patients of rheumatic heart disease, mitral stenosis and evaluation of various cytokines in pulmonary hypertension secondary to rheumatic heart disease.Methods: Total 163 subjects, more than 18 year of age, were enrolled in this study. 84 subjects with rheumatic mitral stenosis (group A) diagnosed on two-dimensional echocardiography (2D echo) and 79 normal healthy volunteers (group B). Patients with mitral stenosis were further divided into subgroups based on severity of mitral stenosis [mitral valve area (MVA >1 cm2 and MVA <1 cm2) (subgroup Aa and Ab)] and presence or absence of pulmonary hypertension [pulmonary arterial systolic pressure (PASP >36 mm Hg) (subgroup Ac and Ad)]. Interleukins IL-6, IL-10, IL-18, tumour necrosis factor alpha (TNF-α) and high-sensitivity C-reactive protein (hs-CRP) levels were assessed in both groups.Results: Mean IL-6, IL-10, IL-18, TNF-α and hs-CRP in group A and group B was 6.57±3.53 and 2.73±1 (p≤0.001), 8.185±2.8 and 3.51±0.86 (p≤0.001), 136.31±89.0 and 47.96±9.76 (p≤0.001), 21.26±18.59 and 5.36±3.57 (p≤0.001), 4.69±6.3 and 2.63±2.22 (p≤0.008) respectively. On subgroup analysis mean TNF-α in subgroup Aa was 20.71±16.84, while in subgroup Ab was 7.56±1.93 (p≤0.001). Mean IL-10 in subgroup Ac and Ad was 8.74±3.29 and 7.47±1.82, respectively. Differences in levels of other cytokines in these subgroups were not found statistically significant.Conclusions: This study finds increased IL-6, IL-10, IL-18, TNF-α and hs-CRP levels in subjects with rheumatic mitral stenosis. Subjects with severe mitral stenosis had increased TNF-α levels. Subjects of mitral stenosis having pulmonary hypertension had increased IL-10 levels.

Background. This study aims to analyze the influence of different dexmedetomidine doses on cognitive function. It works on early periods of patients undergoing laparoscopic extensive total hysterectomy. Method. 119 patients with gynecological cancer underwent a laparoscopic extensive total hysterectomy. The operation was performed at the Affiliated Women’s and Children’s Hospital of Xiamen University from January 2019 to June 2020. The score of MoCA and the level of TNF-α, IL-6, S-100β protein, NSE, and GFAP of each group were compared 1 day before and after operation and 3 and 7 days after operation. Result. In four groups, remifentanil, sufentanil, and propofol were given in the following order: group A > group D > group C > group B. Group A > group D > group C in terms of time spent in the recovery room, extubation, and recovery from anesthesia. The difference between groups B and C was not significant ( P > 0.05 ). Compared with group A, group B scored higher in MoCA at 1 day (T1), 3 days (T2), and 7 days (T3) after operation ( P < 0.05 ). At the same scoring point, the score was group B > group C > group D > group A. The POCD of four groups all occurred at 3 days after surgery. Compared with the T0 point, the level of TNF-α and IL-6 of the four groups at T1 and T2 was significantly increased ( P < 0.05 ). At T3, the level of TNF-α and IL-6 gradually decreased. At various periods, the levels of S-100 protein, NSE, and GFAP in groups B, C, and D were lower than those in group A (P0.05). Group B had a substantially higher rate of bradycardia than the other three groups (P0.05). The incidence of chills, respiratory depression, and restlessness in group A differed significantly from the other three groups ( P < 0.05 ). Conclusion. Using 0.5 μg/kg dexmedetomidine during the perianaesthesia can effectively reduce anesthetic drugs in patients. They had a laparoscopic extensive complete hysterectomy, which helps to reduce the adverse responses and the occurrence of POCD while also protecting brain function.

1.AbstractBackground/AimsRadiotherapy does not only kill tumor cells but also impairs the function of adjacent tissues, especially bone metabolism by damaging bone marrow stromal stem cells (BMSCs). This study aimed to investigate the effect of semaphorin 3a (Sema3a) on BMSCs exposed to 2 Gy radiation.MaterialsBMSCs were divided into four groups, namely, group A (0 Gy), group B (2 Gy), group C (0 Gy + Sema3a), and group D (2 Gy + Sema3a). A Cell Counting Kit-8 kit, Alizarin-Red and Oil-Red-O staining, alkaline phosphatase activity kit, and dichlorodihydro-fluoresce in diacetate were used to test cell proliferation, cell cycle, osteogenic ability, adipogenic ability, and the level of reactive oxygen species (ROS), respectively, in each group. Real-time PCR was performed to test the expression of osteogenic (osteocalcin and Runt-related transcription factor 2), adipogenic (peroxisome proliferator-activated receptor gamma), interleukin (IL)-6, and tumor necrosis factor (TNF)-α genes.ResultsBMSC proliferation, osteogenic differentiation, and the number of cells undergoing division (S+G2 phase of the cell cycle) were found to be lower in group B than in group A. and the cellular levels of ROS, adipogenic differentiation, and expression of inflammatory factors (IL-6 and TNF-α) were higher in group B than in group A. Furthermore, osteogenic differentiation ability was higher in group D than in group B, and adipogenic differentiation ability, cellular levels of ROS, and gene expression of TNF-α and IL-6 were lower in group D than in group B.ConclusionThis study demonstrated that 2 Gy radiation could decrease the osteogenic differentiation ability of BMSCs and increase their adipogenic differentiation ability by increasing the production of ROS. However, Sema3a could reduce these side effects by decreasing the levels of ROS.

Catecholamines have both anti-inflammatory and vasoactive properties. A decreased cardiac response to catecholamines has been associated with a high risk of death in sepsis and septic shock. The aim of this study was to investigate the effects of epinephrine (EPI) on heart rate variability and autonomic balance, as well as cytokine levels, in a rat sepsis model. Thirty-six male Sprague-Dawley rats were assigned to 4 experimental groups and 2 control groups of 6 rats each. The rats in the experimental groups were inoculated with a lipopolysaccharide (LPS, endotoxin) to establish a sepsis model. Group A received only LPS; group B received LPS, antecedent EPI and the nonselective beta-blocker propranolol; group C received LPS and antecedent EPI; and group D received LPS, antecedent EPI and the selective beta1-blocker esmolol. One control group received EPI and the other received saline placebo. Heart rate variability was analyzed and tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1β (IL-1β) levels were measured. Measurements were carried out at baseline and 0, 0.5, 2, and 4 hours after LPS inoculation. There were significant differences in heart rate variability and cytokine levels between the groups, indicating that LPS infusion caused autonomic imbalance. Antecedent EPI significantly decreased the level of TNF-α in group C compared with group A in which TNF-α level peaked at 2 hours and then declined. Propranolol (group B) but not esmolol (group D) administration resulted in elevated TNF-α levels, comparable to those observed in group A. In conclusion, antecedent administration of EPI in a rat sepsis model inhibits the production of TNF-α possibly via the β2-adrenoreceptor.
