Review
This review is a systematic scientific work on medicinal and traditional use, on the chemical composition of specialized metabolites, volatile and non-volatile, on aspects related to toxicology and phytotherapy of Nigella damascena L. The genus Nigella (Ranunculaceae) is distributed throughout the Mediterranean basin, extending to northern India, and has been divided into three sections. Nigella damanscena L. is traditionally used as an ingredient in food, for example, as flavouring agents in bread and cheese, but is also known in folk medicine, used to regulate menstruation; for catarrhal affections and amenorrhea; as a diuretic and sternutatory; as an analgesic, anti-oedematous, and antipyretic; and for vermifuge and its disinfectant effects. This paper reviews the most dated to the latest scientific research on this species, highlighting the single isolated metabolites and exploring their biological activity. Fifty-seven natural compounds have been isolated and characterised from the seeds, roots, and aerial parts of the plant. Among these constituents, alkaloids, flavonoids, diterpenes, triterpenes, and aromatic compounds are the main constituents. The isolated compounds and the various extracts obtained with solvents of different polarities presented a diverse spectrum of biological activities such as antibacterial, antifungal, antitumour, antioxidant, anti-inflammatory, antipyretic, anti-oedema, and antiviral activities. Various in vitro and in vivo tests have demonstrated the pharmacological potential of β-elemene and alkaloid damascenin. Unfortunately, the largest number of biological studies on this species and its metabolites have been conducted in vitro; therefore, further investigation is necessary to evaluate the toxicological aspects and real mechanisms of action of crude extracts to confirm the therapeutic potential of N. damascena.

Randomized Controlled Trial
Acetaminophen, an analgesic and antipyretic available over-the-counter and used in over 600 medicines, is one of the most consumed drugs in the USA. Recent research has suggested that acetaminophen's effects extend to the blunting of negative as well as positive affect. Because affect is a determinant of risk perception and risk taking, we tested the hypothesis that acute acetaminophen consumption (1000 mg) could influence these important judgments and decisions. In three double-blind, placebo-controlled studies, healthy young adults completed a laboratory measure of risk taking (Balloon Analog Risk Task) and in Studies 1 and 2 completed self-report measures of risk perception. Across all studies (total n = 545), acetaminophen increased risk-taking behavior. On the more affectively stimulating risk perception measure used in Study 2, acetaminophen reduced self-reported perceived risk and this reduction statistically mediated increased risk-taking behavior. These results indicate that acetaminophen can increase risk taking, which may be due to reductions in risk perceptions, particularly those that are highly affect laden.

Archives of Physiology and Biochemistry Dec 2022The aim of this study is to evaluate the anti-obesity, anti-hyperglycaemic, analgesic and antipyretic activities of (GA).
OBJECTIVES
The aim of this study is to evaluate the anti-obesity, anti-hyperglycaemic, analgesic and antipyretic activities of (GA).
MATERIALS AND METHODS
GA methanol and water extracts (GAME, GAWE) were administered to high-fat-high-glucose diet (HFFD) rats.
RESULTS
This study showed that GAME exhibited the highest antioxidant, anti-α-amylase and anti-lipase activities, with half inhibitory concentration (IC50) values 0.067, 1.05 and 2.97 mg/ml respectively. In HFFD rats, the administration of GAME inhibited lipase activity by 36, 37 and 30% in the intestine, pancreas and serum, respectively, reduced body weight by 17.7% and modulated lipid profile. In addition, administration of GAME to HFFD-rats decreased α-amylase activity, improved glucose level and protected liver function. Furthermore, the administration of GA extracts to rats revealed antipyretic (reduction in writhing by 64%) and analgesic (decrease of temperature by 1.11 °C) activities.
CONCLUSION
This study showed that GA extracts exhibited an anti-obesity, anti-hyperglycaemia, anti-pyretic and analgesic activities.

Intestinal inflammation is a complex and recurrent inflammatory disease. Pharmacological and pharmacodynamic experiments showed that aspirin eugenol ester (AEE) has good anti-inflammatory, antipyretic, and analgesic effects. However, the role of AEE in regulating intestinal inflammation has not been explored. This study aimed to investigate whether AEE could have a protective effect on LPS-induced intestinal inflammation and thus help to alleviate the damage to the intestinal barrier. This was assessed with an inflammation model in Caco-2 cells and in rats induced with LPS. The expression of inflammatory mediators, intestinal epithelial barrier-related proteins, and redox-related signals was analyzed using an enzyme-linked immunosorbent assay (ELISA), Western blotting, immunofluorescence staining, and RT-qPCR. Intestinal damage was assessed by histopathological examination. Changes in rat gut microbiota and their functions were detected by the gut microbial metagenome. AEE significantly reduced LPS-induced pro-inflammatory cytokine levels ( < 0.05) and oxidative stress levels in Caco-2 cells and rats. Compared with the LPS group, AEE could increase the relative expression of Occludin, Claudin-1, and zonula occludens-1 (ZO-1) and decrease the relative expression of kappa-B (NF-κB) and matrix metalloproteinase-9. AEE could significantly improve weight loss, diarrhea, reduced intestinal muscle thickness, and intestinal villi damage in rats. Metagenome results showed that AEE could regulate the homeostasis of the gut flora and alter the relative abundance of and . Flora enrichment analysis indicated that the regulation of gut flora with AEE may be related to the regulation of glucose metabolism and energy metabolism. AEE could have positive effects on intestinal inflammation-related diseases.

Periplaneta americana is a common traditional Chinese medicinal material which has been used to treat arthritis, fever, aches, pains, and inflammation of the extremities for several hundred years. However, little scientific data exists in literature to support its use. The purpose of this study was to evaluate the antipyretic, anti-inflammatory and analgesic activities of Periplaneta americana extract (PAE) and explore its underlying mechanism. The antipyretic, anti-inflammatory and analgesic activities were evaluated by LPS-induced fever, carrageenan-induced paw edema, abdominal writhing, hot plate and formalin tests, respectively. The mechanism of action was explored by antioxidant activity analysis, inflammatory cytokines expression and febrile mediator measurement, and pathway activation analysis. The results from UHPLC-HRMS indicated that the extract was found to contain dopamine, coumarin, dipeptide, vitamin, organic acid, amino acid and its metabolites, and other organic compounds. PAE showed in a dose-dependent manner antioxidant activity and reduced the protein production and mRNA expression of NO, IL-1β, IL-6, and TNF-α in RAW 264.7 cells in vitro. Moreover, PAE significantly and dose-dependently inhibited the writhing responses and licking time in formalin tests, increased response latency in the hot plate test, reduced carrageenan-induced paw edema and inflammation in mice, decreased LPS-induced rT increase in rats. Furthermore, PAE treatment markedly inhibited the increase in the levels of NO, IL-6, IL-1β, TNF-α, PGE and cAMP in plasma of fevered rat, greatly suppressed the activation of inflammatory response pathway and the change of MDA and GSH concentration, MPO and SOD activity as well as FRAP capacity in paw induced by carrageenan injection. In conclusion, the findings suggested that PAE produced potential antinociceptive, anti-inflammatory and antipyretic effects by reducing production of endogenous inflammatory mediators and blocking the MAPK/NF-κB signaling pathway which support the claim for its traditional use in the treatment of various diseases.

Review
ETHNOPHARMACOLOGICAL RELEVANCE
Borneol (BO) represents a global trade-driven spreading of ethnic medicine traceable to the classical age, and won its name specific to its original habitat "Borneo". BO shows broad spectral pharmacological effects, such as anti-inflammatory, analgesic, antipyretic, inducing resuscitation, and widely applied in the protection and treatment of cardiovascular and cerebrovascular diseases, used singly or mostly in compound formulae.
AIM OF THE STUDY
Three stereoscopic configuration forms of BO, l-borneol (LB), d-borneol (DB), and dl-borneol (synthetic, SB), are formulated in broad spectral application, yet their diverse pharmacodynamic and pharmacokinetic properties caused by configurations, and accurate assay and quality assessment are often overlooked. A systematic review and analysis of lumped studies and applications is necessary to clarify the relationship between configuration and its original plant, analysis method, activity and side effect BO in order to guarantee the efficacy and safety during their application.
MATERIALS AND METHODS
The public databases including PubMed, Web of Science, Google Scholar, China National Knowledge Infrastructure were referenced to summarize a comprehensive research and application data of BO published up to date.
RESULTS
This review includes following sections: History and current status, Stereochemistry, Ethnopharmacology, and Quality assessment. In the section of history, the changes of the plant origins of the two isomeric forms of natural BO were described respectively, and the methods for synthetic racemate SB were also included. The section of stereochemistry deals with the stereoscopic structures, physical/chemical property, optical rotation of the three forms of BO, as well as the main related substances like isoborneol, obtained in SB via chemical transformation of camphor and turpentine oil. In the section of Ethnopharmacology, pharmacological activities and pharmacokinetics of different forms of BO were discussed. BO is usually used as an "adjuvant", by enhancing the permeability of the blood-brain barrier and intervene the ADME/T pathways of the other ingredients in the same formulation. In the section of quality assessment, the analytical methods, including chromatography, especially GC, and spectroscopy were addressed on the chiral separation of the coexisting enantiomers.
CONCLUSIONS
This overview systematically summarized three forms of BO in terms of history, stereochemistry, ethnopharmacology, and quality assessment, which, hopefully, can provide valuable information and strategy for more reasonable application and development of the globally reputed ethnic medicine borneol with characteristics in stereochemistry.

BMC Infectious Diseases Aug 2023Refractory Mycoplasma pneumoniae pneumonia (RMPP) cause damage of pulmonary function and physical therapy assisting medical treatment is needed.
BACKGROUNDS
Refractory Mycoplasma pneumoniae pneumonia (RMPP) cause damage of pulmonary function and physical therapy assisting medical treatment is needed.
OBJECTIVE
The aim of this study was to investigate the effect of interesting respiratory rehabilitation training on pulmonary function in children with RMPP.
METHODS
A total of 76 children with diagnoses of RMPP in our hospital from January 2020 to February 2021 were enrolled in this prospective study. According to the random number table method, they were divided into the control group and the study group, with 38 cases in each group. The control group were given conventional treatment, and the study group received interesting respiratory rehabilitation training in the basis of conventional treatment. The antipyretic time, disappearance time of pulmonary shadow and cough, length of hospital stay, pulmonary function (first second of expiratory volume (FEV1), forced vital capacity (FVC), FEV1/FVC) at 1 day before and after intervention, serum interleukin-6 (IL-6), C-reactive protein (CRP), tumor necrosis factor (TNF-α), and quality of life (Pediatric Quality of Life Inventory, PedsQL 4.0 scale) were observed in the two groups.
RESULTS
The antipyretic time, disappearance time of pulmonary shadow and cough, length of hospital stay in the study group were shorter than those in the control group (P < 0.05). One day before intervention, there was no significant difference in FVC, FEV1, FEV1/FVC IL-6, CRP, and TNF-α between the two groups (P > 0.05). One day after intervention, FVC, FEV1 and FEV1/FVC in the study group were better than those in the control group (P < 0.05), and the levels of IL-6, CRP, and TNF-α in the study group were lower than those in the control group with significant difference (P < 0.05). One day before intervention, there were no significant differences in physiological function, emotional function, social function, and school function between the two groups (P > 0.05). After intervention, physiological function, emotional function, social function, and school function of the study group were better than those of the control group (P < 0.05).
CONCLUSION
The interesting respiratory rehabilitation training can effectively improve the pulmonary function of children with RMPP, with strong flexibility, which is worthy of clinical application.

PURPOSE
Metamizole, which has antipyretic and pain-relieving properties, is generally used to treat fever in children who do not respond to paracetamol treatment. The most remarkable side effect of metamizole is that it causes myelotoxicity independently of dose. In this study, we aimed to present the clinical features of paediatric patients who developed agranulocytosis after the use of metamizole and draw attention to this side effect.
METHODS
The patients who were admitted to Eskişehir Osmangazi University Faculty of Medicine Hospital, Pediatric Infectious Diseases and Pediatric Hematology Service, between January 1, 2015, and December 31, 2018, with a diagnosis of secondary agranulocytosis to metamizole use were examined retrospectively.
RESULTS
In all, 12 patients were included in the study; oral metamizole was used in these patients for fever reduction. The mean absolute neutrophil count was 225/mm ± 226 (0-600/mm) at admission, and the neutrophil value of 11 patients was < 500/mm. The mean length of hospitalisation of the patients was 9.92 ± 8 (3-28) days. Eight patients received intravenous antibiotic therapy and four patients received at least one of the following treatments: intravenous immunoglobulin, granulocyte colony-stimulating factor and methylprednisolone. Bone marrow aspiration examination showed neutrophil/band maturation delaying in the myeloid series with normocellular bone marrow in three patients. Hypocellularity in the bone marrow and decrease in myeloid precursors were observed in three patients. There were no fatal cases.
CONCLUSION
The development of agranulocytosis after the use of metamizole causes long-term hospitalisation and may require the use of medications in treatment management. Considering the availability of alternative options to treat fever and pain, and given the side-effect profile of metamizole, it should not be the preferred, first-line antipyretic treatment in children.

Review
Acetaminophen (APAP) is the most popular mild analgesic and antipyretic drug used worldwide. APAP overdose leads to drug-induced hepatotoxicity and can cause hepatic failure if treatment delayed. It is adequately comprehended that the metabolism of high-dose APAP by cytochrome P450 enzymes generates N-acetyl-p-benzoquinone imine (NAPQI), a toxic metabolite, which leads to glutathione (GSH) depletion, oxidative stress, and activation of various complex molecular pathways that initiate liver injury and downstream hepatic necrosis. Administration of activated charcoal followed by N-acetylcysteine (NAC) is considered the mainstay therapy; however, including side effects and limitation of rescuing for the delayed patients where liver transplantation may be a lifesaving procedure. Many complex signal transduction pathways such as c-Jun NH-terminal kinase (JNK), mammalian target of rapamycin (mTOR), nuclear factor (NF)-κB, and NF (erythroid-derived 2)- like 2 (Nrf2) are involved in the development of APAP hepatotoxicity, but yet hasn't been comprehensively studied; thus, the search for effective antidotes and better management strategies continues. Here, we reviewed the most current advances to elucidate the etiological factors and therapeutic targets that could provide better strategies for the management of APAP-induced hepatotoxicity.

Review
INTRODUCTION
Paracetamol is the most commonly used antipyretic and analgesic in pregnancy. It is also increasingly used off-label in the neonatal intensive care unit. Despite the frequent use of paracetamol, concerns have been raised regarding the high variability in neonatal dosing regimens and the long-term safety of early life exposure.
OBJECTIVE
To investigate the available evidence on the long-term safety of prenatal and neonatal paracetamol exposure.
METHODS
We conducted a systematic search of the electronic databases Ovid Medline, Ovid Embase and Web of Science from inception to August 2021 for original research studies of any design that described the use of paracetamol in the prenatal or neonatal (within the first four weeks of life) periods and examined the occurrence of neurodevelopmental, atopic or reproductive adverse outcomes at or beyond birth.
RESULTS
We identified 1313 unique articles and included 30 studies in the final review. Of all studies, 27 (90%), two (7%) and one (3%) were on the long-term safety of prenatal, neonatal and both prenatal and neonatal exposure, respectively. Thirteen (46%), 11 (39%) and four (15%) studies examined neurodevelopmental, atopic and reproductive outcomes. Eleven (100%), 11 (100%), and three (27%) studies on prenatal exposure reported adverse neurodevelopmental, atopic and reproductive outcomes. Only one study found a possible correlation between neonatal paracetamol exposure and long-term adverse outcomes.
CONCLUSIONS
The available evidence, although limited, suggests a possible association between prenatal paracetamol exposure and an increased risk of neurodevelopmental, atopic and reproductive adverse outcomes. There is an immediate need for robust data on the long-term safety of paracetamol exposure in the prenatal and neonatal periods.
