Objective: To explore the pre-treatment and efficacy analysis of comprehensive anti-inflammatory treatment for lymphedema in patients with irritating contact dermatitis. Method: Convenience sampling method was used to observe the skin of 160 patients with upper limb lymphedema admitted to the lymphedema outpatient department of our hospital. They were divided into an observation group (80 cases) and a control group (80 cases), and both groups received a course of comprehensive anti-inflammatory treatment (20 treatments). The control group received routine skin care;On the basis of the control group, the observation group received pre-treatment of the affected limb skin: Laofuzi herbal ointment was applied externally to the prone areas of irritating contact dermatitis (such as the upper arm, inner forearm, and cubital fossa). Result: The incidence of irritating contact dermatitis in the observation group was significantly lower than that in the control group (P 0.05). Patients in the observation group felt significantly better in terms of comfort, skin moisture, and itching relief after being wrapped with low elasticity bandages than those in the control group (P Conclusion: Preventive treatment can effectively reduce the incidence of irritating contact dermatitis, prolong the time of stress treatment, thereby increasing efficacy and improving patient compliance. 展开更多

Objective:To investigate the analgesic and anti-inflammatory effects of the methanolic extract of the leaves of Triumfetta rhomboidea on mice and rats respectively.And to screen the phytochemical constituent of the extract. Methods:The analgesic effect was determined by acetic acid-induced writhing test in mice.While the anti-inflammatory activity was determined by egg albumin-induced oedema of the rat paw.Phytochemical screening was done by standard procedures.Results:Triumfetta rhomboidea leaf extract(50 -400 mg/kg) caused a statistically significant inhibition on the egg albumin-induced eodema or inflammation in Wister albino rats with P【0.001(ANOVA).This effect was higher than the observed effect with Piroxicam(0.5 mg/kg) which was used as a standard.The effect was also dose-dependent.Furthermore,Triumfetta rhomboidea extract caused a statistically significant reduction in the number of acetic acid-induced writhing in mice,with P【0.001(ANOVA).These effects were also does-dependent and greater than the analgesic effects by paracetamol which was used as a reference drug.Phytochemical screening revealed the presence of flavonoids,steroids, triterpenoids alkaloids,tannins and saponins in Truimfetta rhomboidea leaf extract.Conclusion:Triumfetta rhomboidea can be recommended for acute inflammatory disorders and diseases associated with pains.This also supports its traditional use as an anti-snake bite and anti-cancer or anti-tumor agent.Further study is on the way to find out the mechanism of its action and also to isolate,identify and characterize the active principle responsible for these effects in this plant. 展开更多

Objective: To explore anti-inflammatory activities of organic extract and its semi-purified fractions(ethanol, acetone, methanol/dichloromethane) from the Mediterranean gorgonian Eunicella singularis. Methods: The anti-inflammatory and analgesic activities were evaluated, using the carrageenan-induced rat paw edema model and the acetic acid writhing test in mice. The gastroprotective activity was determined using HCl/Et OH induced gastric ulcers in rats. The purification and structure elucidation of compound(s) from the more effective fraction were determined by chromatographic and spectroscopic methods and in comparison with data reported in the literature. Results: The fraction F-Et OH showed an important antiinflammatory activity associated with significant analgesic and gastroprotective properties. The purification and structure elucidation of compound(s) from this fraction lead to the identification of one diterpenoid and four sterols. Conclusions: These results suggested that components from the active fraction can be used to treat various anti-inflammatory diseases. 展开更多

Non-steroidal anti-inflammatory drugs (NSAIDs) constitute a family of drugs, which taken as a group, represents one of the most frequently prescribed around the world. Thus, not surprisingly NSAIDs, along with antiinfectious agents, list on the top for causes of DrugInduced Liver Injury (DILI). The incidence of liver disease induced by NSAIDs reported in clinical studies is fairly uniform ranging from 0.29/100 000 [95% confidence interval (CI): 0.17-051] to 9/100 000 (95% CI: 6-15). However, compared with these results, a higher risk of liver-related hospitalizations was reported (3-23 per 100 000 patients). NSAIDs exhibit a broad spectrum of liver damage ranging from asymptomatic, transient, hyper-transaminasemia to fulminant hepatic failure. However, under-reporting of asymptomatic, mild cases, as well as of those with transient liver-tests alteration, in conjunction with reports non-compliant with pharmacovigilance criteria to ascertain DILI and flawed epidemiological studies, jeopardize the chance to ascertain the actual risk of NSAIDs hepatotoxicity. Several NSAIDs, namely bromfenac, ibufenac and benoxaprofen, have been withdrawn from the market due to hepatotoxicity; others like nimesulide were never marketed in some countries and withdrawn in others. Indeed, the contro-versy concerning the actual risk of severe liver disease persists within NSAIDs research. The present work intends (1) to provide a critical analysis of the dissimilar results currently available in the literature concerning the epidemiology of NSAIDS hepatotoxicity; and (2) to review the risk of hepatotoxicity for each one of the most commonly employed compounds of the NSAIDs family, based on past and recently published data. 展开更多

Treatment of inflammatory bowel disease has significantly improved since the introduction of biological agents, such as infliximab, adalimumab, certolizumab pegol, and golimumab. The Food and Drug Administration has classified these factors in category B, which means that they do not demonstrate a fetal risk. However, during pregnancy fetuses are exposed to high anti-tumor necrosis factor(TNF) levels that are measurable in their plasma after birth. Since antibodies can transfer through the placenta at the end of the second and during the third trimesters, it is important to know the safety profile of these drugs, particularly for the fetus, and whether maintaining relapse of the disease compensates for the potential risks of fetal exposure. The limited data available for the anti-TNF drugs to date have not demonstrated any significant adverse outcomes in the pregnant women who continued their therapy from conception to the first trimester of gestation. However, data suggest that antiTNFs should be discontinued during the third trimester, as they may affect the immunological system of the newborn baby. Each decision should be individualized, based on the distinct characteristics of the patient and her disease. Considering all the above, there is a need for more clinical studies regarding the effect of antiTNF therapeutic agents on pregnancy outcomes. 展开更多

Atopic dermatitis is classified as a chronic inflammatory skin disease, which is characterized by alterations in barrier function and immune system of the skin. In a previous study, the efficacy of REPAVAR ATOPIC SKIN BODY CREAM EXTREME (a product containing “SKIN CALM COMPLEX”) on the epidermal barrier structure was demonstrated. However, the product has also been formulated to improve inflammation and itching. The aim of this study is to analyze product effectiveness on skin inflammation and itching which is associated with atopic dermatitis, by quantification of IL-1α and IL-8 interleukins secreted by human keratinocytes from reconstructed epidermis by ELISA assay. Mature (aged 17 days) sample tissues were treated with pro-inflammatory agents (PBS 1X and LPS) and with the product containing synergistic mix from plants extracts and Dihydroavenanthramide D, among other ingredients (“SKIN CALM COMPLEX”) for 24 hours. Measuring the amounts of interleukins by ELISA assay showed 1) decreased levels of IL-1α and 2) no differences about IL-8 secretion. Product REPAVAR ATOPIC SKIN BODY CREAM EXTREME has an anti-inflammatory effect on the release of pro-inflammatory cytokines, becoming an effective preventive agent on inflammation and itching due to maintenance and improvement of the keratinocyte epidermal structure. 展开更多

[Objectives] To study the anti-inflammatory activity and mechanism of salvianolic acid A(Sal A), salvianolic acid C(Sal C), and rosmarinic acid(RA) on HAECs induced by TNF-α. [Methods] VE was used as a positive control and TNF-α induced human aortic endothelial cells(HAECs) were selected as the inflammation model cells. The levels of IL-6, MCP-1 were determined using ELISA. The mRNA levels of IL-6, MCP-1, ICAM-1, P-selectin and NF-κB were analyzed by quantitative RT-PCR. The protein expression of NF-κB was determined by western blot. The adhesion of U937 to HAECs was assessed by BCECF/AM labeling assay. Immunohistochemistry detection was used for ICAM-1 and P-selectin expression levels in TNF-induced HAECs, and DHE detection for the ROS production in HAECs induced by TNF-α. [Results] TNF-α-induced over-expressions of IL-6, MCP-1, NF-κB, ICAM-1 and P-selectin in HAECs were down-regulated by Sal A, Sal C and RA both in mRNA or protein levels, respectively. Meanwhile Sal A, Sal C and RA could significantly inhibit the production of ROS and U937 cells adhesion to HAECs. [Conclusions] Phenolic acids could inhibit TNF-α-induced inflammatory responses on HAECs and the mechanism might be related to inhibition of the production of ROS and blocking NF-κB signaling pathway. 展开更多
