Bronchial asthma (BA) is one of the common childhood diseases that affects the respiratory system characterized by recurrent cough, wheezing, chest tightness and difficulty with breathing. The two conditions are different manifestations of allergic disease of the airway;the composition of the inflammatory substrate in the mucosa of allergic patients is similar to the late-phase allergic response seen elsewhere in the respiratory tract, such as in bronchial asthma. Aim: The aim was to compare the impacts of allergic rhinitis and bronchial asthma on tympanometric parameters in children. Patients & Methods: This is a hospital based comparative cross-sectional study. Two groups of participants aged 4 - 12 years, one group with documented clinical diagnosis of allergic rhinitis and the other group with documented clinical diagnosis of bronchial asthma were consecutively selected from ear, nose and throat (ENT) and pediatrics cardiopulmonary outpatient clinics of Aminu Kano Teaching Hospital Kano respectively. Equal number of children aged 4 - 12 years with no history of ENT diseases or bronchial asthma that were selected from elementary schools within the same community served as a control group. An interviewer-administered questionnaire was filled out for all the participants, complete ENT and chest examinations were carried out and subsequently all the selected participants had tympanometry done, findings were recorded and analyzed. Results: The mean age of participants with bronchial asthma was found to be 7.5 ± 2.6 years while participants with allergic rhinitis had the mean age of 6.8 ± 2.1 years. The mean middle ear pressure (MEP) of participants with bronchial asthma was found to be -15.22 dapa and -40.32 dapa in those with allergic rhinitis. Acoustic reflex was found to be absent in 15.4% of the participants with bronchial asthma and 29.6% of allergic rhinitis participants. Type B tympanogram was found in 2.8% of bronchial asthma participants and 7.3% in participants with allergic rhinitis. Type C tympanogram was found in 4.6% of participants with bronchial asthma and 15.5% of participants with allergic rhinitis. Type A tympanogram was found in 90% of participants with bronchial asthma and 75% of participants with allergic rhinitis. The difference between type A, B and C tympanograms of participants with bronchial asthma and those with allergic rhinitis was found to be statistically significant (Type A χ<sup>2</sup> = 14.62, df = 4, p value = 0.01, Type B χ<sup>2</sup> = 14.06, df = 4, p value = 0.01, Type C χ<sup>2</sup> = 17.01, df = 6, p value = 0.01). Conclusion: Participants with allergic rhinitis were found to have more abnormalities of tympanometric parameters compared to participants with bronchial asthma which signifies allergic rhinitis conferred an increased risk of having middle ear diseases and otitis media with effusion compared to bronchial asthma.展开更多

Modern medicine still lacks effective treatment methods for such diseases. In recent years, clinical cases of children and adolescents have also increased year by year. Objective: In order to provide references for further study and practical treatment on allergic rhinitis, this paper summarized the advances on the treatment of allergic rhinitis by Traditional Chinese Method (TCM) and Western Medicine Method (WMM) in clinical practice and study. Method: Through detailed review and study of literatures, the theory and clinical experiences in TCM, WMM, and integrated treatment of the two were analyzed and summarized. Conclusions: TCM conducts personalized treatment for patients by syndrome differentiation. The main means are to regulate the body’s health Qi and Yang Qi. Drugs, acupuncture, psychology and other means of treatment are all used and the effects of treatment are very well. WMM mainly relieves the infiltration of local inflammatory cells, expands local capillaries, improves nasal permeability and alleviates the occurrence of allergic graduation by using kinds of drugs or surgery. Though both TCM and WMM are effective and have some common characteristics and each has its own characteristics, the combination of TCM and WMM has a good prospect and is more effective and can effectively reduce the adverse reactions of patients, because TCM is to change patients’ own constitution and the starting point of WMM is to eliminate the pathogen.展开更多

It is found to be good for anti-inflammation. However, its precise anti-allergic rhinitis effect and mechanism remain unknown. In our work, the effect of KMCP on allergic rhinitis(AR)induced by ovalbumin(OVA)was investigated. We found that the number of nasal rubbing and sneezing, the eosinophil(EOS)count in the nasal mucosa, and the serum levels of histamine(HIS), OVA-specific immunoglobulin E(OVA-sIgE)and interleukin-4(IL-4)were decreased, and the histopathological changes of nasal mucosa were inhibited. Additionally, the experiments further proved that the KMCP treatment could exert substantial effects on short-chain fatty acids(SCFAs)metabolism in the cecum as well. Overall findings suggest that KMCP could suppress the inflammatory response in AR mice, and serve as a novel curative therapeutic for AR without side effects.展开更多

文摘Drug-induced liver injury(DILI)is caused by various drugs with complex pathogenesis,and diverse clinical and pathological phenotypes.Drugs damage the liver directly through drug hepatotoxicity,or indirectly through drug-mediated oxidative stress,immune injury and inflammatory insult,which eventually lead to hepatocyte necrosis.Recent studies have found that the composition,relative content and distribution of gut microbiota in patients and animal models of DILI have changed significantly.It has been confirmed that gut microbial dysbiosis brings about intestinal barrier destruction and microorganisms translocation,and the alteration of microbial metabolites may cause or aggravate DILI.In addition,antibiotics,probiotics,and fecal microbiota transplantation are all emerging as prospective therapeutic methods for DILI by regulating the gut microbiota.In this review,we discussed how the altered gut microbiota participates in DILI.

文摘Drug-induced interstitial lung disease(DILD)is the most common pulmonary adverse event of anticancer drugs.In recent years,the incidence of anticancer DILD has gradually increased with the rapid development of novel anticancer agents.Due to the diverse clinical manifestations and the lack of specific diagnostic criteria,DILD is difficult to diagnose and may even become fatal if not treated properly.Herein,a multidisciplinary group of experts from oncology,respiratory,imaging,pharmacology,pathology,and radiology departments in China has reached the“expert consensus on the diagnosis and treatment of anticancer DILD”after several rounds of a comprehensive investigation.This consensus aims to improve the awareness of clinicians and provide recommendations for the early screening,diagnosis,and treatment of anticancer DILD.This consensus also emphasizes the importance of multidisciplinary collaboration while managing DILD.
文摘Objective:To evaluate the effect of myricetin on ovalbumin(OVA)-induced allergic rhinitis in mice.Methods:Mice were sensitized and challenged using OVA(5%,500 mL)intraperitoneally and intranasally,respectively,on an alternative day for 14 days,followed by administration of myricetin(50,100,and 200 mg/kg)till day 21.Nasal symptoms,biochemical parameters,protein expressions,and histopathology were observed.Results:OVA-induced increased nasal symptoms including rubbing,sneezing,and discharge were significantly reduced by myricetin(100and 200 mg/kg)(P<0.05).Myricetin also protected against histamine challenge and attenuated elevated serum immunoglobulin E(IgE;total and OVA-specific),total IgG1,andβ-hexosaminidase levels,as well as leukotriene C4 and interleukins levels in nasal lavage fluid(P<0.05).Western blot analysis showed that myricetin significantly upregulated the protein expression of T-box expressed in T cells,while downregulating the protein expression of GATA binding protein 3,NF-κB,and IκB-α(P<0.05).Additionally,OVA-induced histopathological abberations in the nasal mucosa was markedly ameliorated by myricetin treatment(P<0.05).Conclusions:Myricetin exerts anti-allergic effects against OVAinduced allergic rhinitis via regulating Th1/Th2 balance.
文摘Background: Allergic rhinitis (AR) is a multifocal IgE-mediated type I hypersensitivity reaction that affects sino-nasal mucosa and is characterized by excessive sneezing, watery rhinorrhea, nasal itching, nasal stuffiness and eyes itching. Bronchial asthma (BA) is one of the common childhood diseases that affects the respiratory system characterized by recurrent cough, wheezing, chest tightness and difficulty with breathing. The two conditions are different manifestations of allergic disease of the airway;the composition of the inflammatory substrate in the mucosa of allergic patients is similar to the late-phase allergic response seen elsewhere in the respiratory tract, such as in bronchial asthma. Aim: The aim was to compare the impacts of allergic rhinitis and bronchial asthma on tympanometric parameters in children. Patients & Methods: This is a hospital based comparative cross-sectional study. Two groups of participants aged 4 - 12 years, one group with documented clinical diagnosis of allergic rhinitis and the other group with documented clinical diagnosis of bronchial asthma were consecutively selected from ear, nose and throat (ENT) and pediatrics cardiopulmonary outpatient clinics of Aminu Kano Teaching Hospital Kano respectively. Equal number of children aged 4 - 12 years with no history of ENT diseases or bronchial asthma that were selected from elementary schools within the same community served as a control group. An interviewer-administered questionnaire was filled out for all the participants, complete ENT and chest examinations were carried out and subsequently all the selected participants had tympanometry done, findings were recorded and analyzed. Results: The mean age of participants with bronchial asthma was found to be 7.5 ± 2.6 years while participants with allergic rhinitis had the mean age of 6.8 ± 2.1 years. The mean middle ear pressure (MEP) of participants with bronchial asthma was found to be -15.22 dapa and -40.32 dapa in those with allergic rhinitis. Acoustic reflex was found to be absent in 15.4% of the participants with bronchial asthma and 29.6% of allergic rhinitis participants. Type B tympanogram was found in 2.8% of bronchial asthma participants and 7.3% in participants with allergic rhinitis. Type C tympanogram was found in 4.6% of participants with bronchial asthma and 15.5% of participants with allergic rhinitis. Type A tympanogram was found in 90% of participants with bronchial asthma and 75% of participants with allergic rhinitis. The difference between type A, B and C tympanograms of participants with bronchial asthma and those with allergic rhinitis was found to be statistically significant (Type A χ<sup>2</sup> = 14.62, df = 4, p value = 0.01, Type B χ<sup>2</sup> = 14.06, df = 4, p value = 0.01, Type C χ<sup>2</sup> = 17.01, df = 6, p value = 0.01). Conclusion: Participants with allergic rhinitis were found to have more abnormalities of tympanometric parameters compared to participants with bronchial asthma which signifies allergic rhinitis conferred an increased risk of having middle ear diseases and otitis media with effusion compared to bronchial asthma.
文摘Background: Allergic rhinitis is a common and high incidence disease in clinic, which has a certain impact on the work, life and social activities of patients. Modern medicine still lacks effective treatment methods for such diseases. In recent years, clinical cases of children and adolescents have also increased year by year. Objective: In order to provide references for further study and practical treatment on allergic rhinitis, this paper summarized the advances on the treatment of allergic rhinitis by Traditional Chinese Method (TCM) and Western Medicine Method (WMM) in clinical practice and study. Method: Through detailed review and study of literatures, the theory and clinical experiences in TCM, WMM, and integrated treatment of the two were analyzed and summarized. Conclusions: TCM conducts personalized treatment for patients by syndrome differentiation. The main means are to regulate the body’s health Qi and Yang Qi. Drugs, acupuncture, psychology and other means of treatment are all used and the effects of treatment are very well. WMM mainly relieves the infiltration of local inflammatory cells, expands local capillaries, improves nasal permeability and alleviates the occurrence of allergic graduation by using kinds of drugs or surgery. Though both TCM and WMM are effective and have some common characteristics and each has its own characteristics, the combination of TCM and WMM has a good prospect and is more effective and can effectively reduce the adverse reactions of patients, because TCM is to change patients’ own constitution and the starting point of WMM is to eliminate the pathogen.
文摘BACKGROUND Interleukin-17(IL-17)inhibitors are known to cause exacerbation or new onset of inflammatory bowel disease upon administration.However,few reports have described characteristic endoscopic and histopathologic findings,and no small intestinal lesions have been reported so far.CASE SUMMARY A woman in her 60s with psoriasis was administered ixekizumab(IXE),an anti-IL-17A antibody,for the treatment of psoriasis.Twenty months after commencing treatment,the patient visited our hospital because of persistent diarrhea.Blood tests performed at the time of the visit revealed severe inflammation,and colonoscopy revealed multiple round ulcers throughout the colon.A tissue biopsy of the ulcer revealed infiltration of inflammatory cells and granuloma-like findings in the submucosal layer.Capsule endoscopy revealed multiple jejunal erosions.After the withdrawal of IXE,the symptoms gradually improved,and ulcer reduction and scarring of the colon were endoscopically confirmed.CONCLUSION To the best of our knowledge,17 reports have documented IL-17 inhibitorinduced entero-colitis with endoscopic images,endoscopic findings,and pathological characteristics,including the present case.Nine of these cases showed diffuse loss of vascular pattern,coarse mucosa/ulcer formation in the left colon,and endoscopic findings similar to those of ulcerative colitis.In the remaining eight cases,discontinuous erosions and ulcerations from the terminal ileum to the rectum were seen,with endoscopic findings similar to those of Crohn’s disease.In this case,the findings were confirmed by capsule endoscopy,which has not been previously reported.

文摘According to the proportion of 1:1, konjac flour and mulberry leaf powder are compounded into a kind of dietary fiber source(KMCP). It is found to be good for anti-inflammation. However, its precise anti-allergic rhinitis effect and mechanism remain unknown. In our work, the effect of KMCP on allergic rhinitis(AR)induced by ovalbumin(OVA)was investigated. We found that the number of nasal rubbing and sneezing, the eosinophil(EOS)count in the nasal mucosa, and the serum levels of histamine(HIS), OVA-specific immunoglobulin E(OVA-sIgE)and interleukin-4(IL-4)were decreased, and the histopathological changes of nasal mucosa were inhibited. Additionally, the experiments further proved that the KMCP treatment could exert substantial effects on short-chain fatty acids(SCFAs)metabolism in the cecum as well. Overall findings suggest that KMCP could suppress the inflammatory response in AR mice, and serve as a novel curative therapeutic for AR without side effects.
文摘BACKGROUND There are many adverse reactions in the treatment of allergic rhinitis(AR)mainly with conventional drugs.Leukotriene receptor antagonists,glucocorticoids and nasal antihistamines can all be used as first-line drugs for AR,but the clinical effects of the three drugs are not clear.AIM To examine the impact of glucocorticoids,antihistamines,and leukotriene receptor antagonists on individuals diagnosed with AR,specifically focusing on their influence on serum inflammatory indexes.METHODS The present retrospective study focused on the clinical data of 80 patients diagnosed and treated for AR at our hospital between May 2019 and May 2021.The participants were categorized into the control group and the observation group.The control group received leukotriene receptor antagonists,while the observation group was administered glucocorticoids and antihistamines.Conducted an observation and comparison of the symptoms,physical sign scores,adverse reactions,and effects on serum inflammatory indexes in two distinct groups of patients,both before and after treatment.RESULTS Subsequent to treatment,the nasal itching score,sneeze score,runny nose score,nasal congestion score,and physical signs score exhibited notable discrepancies(P<0.05),with the observation group demonstrating superior outcomes compared to the control group(P<0.05).The interleukin(IL)-6,IL-10,tumor necrosis factor-alpha,Soluble Intercellular Adhesion Molecule-1,Leukotriene D4 after treatment were significantly different and the observation group It is better than the control group,which is statistically significant(P<0.05).Following the intervention,the incidence of adverse reactions in the observation group,including symptoms such as nasal dryness,discomfort in the throat,bitter taste in the mouth,and minor erosion of the nasal mucosa,was found to be 7.5%.This rate was significantly lower compared to the control group,which reported an incidence of 27.5%.The difference between the two groups was statistically significant(P<0.05).CONCLUSION Glucocorticoids and antihistamines have obvious therapeutic effects,reduce serum inflammatory index levels,relieve symptoms and signs of patients,and promote patients'recovery,which can provide a reference for clinical treatment of AR.

文摘Objective:To study the key target genes and signaling pathways in the treatment of Allergic Rhinitis(AR)with Radix Aconiti Lateralis Preparata(aka Fuzi).Methods:The TCMPS and PubChem databases were used to screen the active ingredients and target genes of Fuzi using oral bioavailability and drug similarity as screening conditions,and the GeneCards database was used to screen the target genes of AR.The online tool Venny2.1 was used to screen the target genes of Fuzi for the treatment of Allergic Rhinitis;the STRING database was used to obtain the protein-protein interaction(PPI)network of drug-disease targets,and the key target genes were identified by the MCC algorithm.The potential biological processes and signaling pathways were identified by GO enrichment and KEGG enrichment analysis.Finally,animal experiments were conducted to demonstrate the therapeutic effect ofFuzi on Allergic Rhinitis.Results:The TCMSP,PubChem and GeneCards databases were used to screen the 21 active compound components of Fuzi and 68 potential therapeutic target genes of Fuzi for Allergic Rhinitis.PPI network analysis identified the top ten key target genes,namely:PTGS2,TNF,IL6,AKT1,ALB,STAT3,CCL2,CXCL8,VEGFA and JUN,GO functional and KEGG pathway enrichment analysis showed that the significantly enriched functions and pathways of Fuzi on Allergic Rhinitis were closely related to Allergic Rhinitis.Finally,animal experiments were conducted to verify that Fuzi is effective in the treatment of Allergic rhinitis.Conclusion:Increased expression of IL-6 and TNF-αin nasal mucosal tissues of patients with Allergic Rhinitis was positively correlated with indicators related to the disease activity of AllergicRhinitis.Fuzi ameliorated the inflammatory changes in mice with Allergic Rhinitis by inhibiting the activation of Toll-like signaling pathway in the nasal mucosa and decreasing the expression activity of IL-6 and TNF-α.
文摘BACKGROUND Empirical use of potentially hepatotoxic drugs in the management of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection is considered as one of the major etiopathogenetic factors for liver injury.Recent evidence has shown that an underlying genetic factor may also occur.Hence,it is important to understand the host genetics and iatrogenic-based mechanisms for liver dysfunction to make timely remedial measures.AIM To investigate drug-induced and genetic perspectives for the development of coronavirus disease 2019(COVID-19)-related liver injury.METHODS Reference Citation Analysis,PubMed,Google Scholar and China National Knowledge Infrastructure were searched by employing the relevant MeSH keywords and pertaining data of the duration,site and type of study,sample size with any subgroups and drug-induced liver injury outcome.Genetic aspects were extracted from the most current pertinent publications.RESULTS In all studies,the hepatic specific aminotransferase and other biochemical indices were more than their prescribed upper normal limit in COVID-19 patients and were found to be significantly related with the gravity of disease,hospital stay,number of COVID-19 treatment drugs and worse clinical outcomes.In addition,membrane bound O-acyltransferase domain containing 7 rs641738,rs11385942 G>GA at chromosome 3 gene cluster and rs657152 C>A at ABO blood locus was significantly associated with severity of livery injury in admitted SARS-CoV-2 patients.CONCLUSION Hepatic dysfunction in SARS-CoV-2 infection could be the result of individual drugs or due to drug-drug interactions and may be in a subset of patients with a geneticpropensity. Thus, serial estimation of hepatic indices in hospitalized SARS-CoV-2 patients shouldbe done to make timely corrective actions for iatrogenic causes to avoid clinical deterioration.Additional molecular and translational research is warranted in this regard.
文摘BACKGROUND A 70-year-old man with hepatitis C virus-related recurrent hepatocellular carcinoma was admitted for further diagnosis of a 1 cm iso-hyperechoic nodule in segment(S)5.CASE SUMMARY Gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging(EOB-MRI)revealed the nodule in S5 with a defect at the hepatobiliary phase,hyperintensity on diffusion weighted imaging(DWI)and hypointensity on apparent diffusion coefficient(ADC)map.Contrast-enhanced computed tomography revealed hypervascularity at the early phase,and delayed contrast-enhancement was observed at the late phase.Contrast-enhanced ultrasound(US)revealed incomplete defect at the late vascular phase.Inflammatory liver tumor,lymphoproliferative disease,intrahepatic cholangiocarcinoma(small duct type)and bile duct adenoma were suspected through the imaging studies.US guided biopsy,however,showed a noncaseating hepatic sarcoid-like epithelioid granuloma(HSEG),and histopathological analysis disclosed spindle shaped epithelioid cells harboring Langhans-type multinucleated giant cells.One month after admission,EOB-MRI signaled the disappearance of the defect at the hepatobiliary phase,of hyperintensity on DWI,of hypointensity on ADC map,and no stain at the early phase.CONCLUSION That the patient had received BNT162b2 messenger RNA(mRNA)coronavirus disease 2019 vaccination 3 mo before the occurrence of HSEG,and that its disappearance was confirmed 4 mo after mRNA vaccination suggested that the drug-induced sarcoidosis-like reaction(DISR)might be induced by the mRNA vaccination.Fortunately,rechallenge of drug-induced DISR with the third mRNA vaccination was not confirmed.

文摘Objective:To explore the effect of"Yingxiang-Hegu"on Th1,Th2-related cytokines and[2]transcription factors T-bet and GATA-3 in rats with allergic rhinitis.Methods:Rats were randomly divided into three groups:blank group,model group and acupoint group.The rat model of ovalbumin(OVA)AR was established,and the general condition of the rats was observed and scored.Acupuncture intervention was performed on the acupoint group on the second day after successful modeling,once per day for 20 min for 10 d.After intervention,the general behavior,behavioral score and histomorphological changes of nasal mucosa were observed.Eosinophils(EOS)were counted under microscope after nasal lavage smear staining,and the contents of total IgE,IFN-γ,IL-12,IL-4 and IL-5 in serum were detected by ELISA.Westernblot and IHC were used to detect the protein level and positive protein expression of specific transcription factors T-bet and GATA-3 in rat nasal mucosa.Results:After the establishment of the model,except for the blank group,the behavioral observation scores of rats in the model group and acupoint group were more than 5 points,indicating that the model was successful.After acupuncture intervention on acupoint"Yingxiang-Hegu",the behavioral score of rats in the acupoint group and western medicine group was significantly lower than that in the model group(P<0.05).Microscopic examination showed that the structure of nasal mucosa in the model group was obviously damaged,cilia were arranged discontinuously,uneven,local congestion and swelling,a large number of epithelial cells exfoliated and necrotic,goblet cell proliferation,obvious inflammatory cell infiltration.The pathological degree of nasal mucosa in the pair point group was significantly less than that in the model group.Compared with the model group,the levels of IFN-γ,IL-2 and IL-12 in serum were significantly increased,while IgE,IL-4,IL-5 and IL-6 were significantly decreased,GATA-3 protein and positive expression in nasal mucosa were significantly decreased and T-bet was significantly increased after acupuncture.Conclusion:Acupuncture at"Yingxiang-Hegu"can effectively improve the nasal sensitive symptoms and control nasal inflammation in AR rats.The mechanism may be that acupuncture at Yingxiang-Hegu can up-regulate the expression of T-bet,decrease the level of GATA-3,promote the production of Th1 cytokines and inhibit the synthesis and secretion of Th2 cells,thus restoring the immune balance of Th1 and Th2.
