Efficacy ofβ2-adrenergic receptor agonist combined with corticosteroid in the treatment of children with cough variant asthma

BACKGROUND Cough variant asthma(CVA)is one of the most common respiratory diseases in children,which has a serious impact on the quality of life and daily activities of children.For severe CVA,immunomodulatory drugs are needed.AIM To evaluate the efficacy of salmeterol combined with budesonide in the treatment of pediatric CVA.METHODS 130 children with CVA from January 2020 to December 2022 were prospectively selected and randomly divided into an observation group(salmeterol combined with budesonide)and a control group(budesonide combined with a placebo).Compare the clinical efficacy of two groups before and after intervention.The evaluation parameters include cough frequency score,nocturnal cough arousal,and lung function indicators.Serum inflammatory markers,immune function markers and airway anatomical indicators were also measured.RESULTS After the intervention,the total effective rate of the observation group was significantly higher than that of the control group,and the cough frequency score and the night cough wake rate of the observation group were lower than that of the control group,with a statistically significant difference.In addition,the changes of lung function indicators,serum markers and immune function markers in the observation group were better than those in the control group.CONCLUSION The clinical efficacy of salmeterol combined with Budesonide in the treatment of CVA is better than that of Budesonide alone.

Superior laryngeal nerve block for treatment of throat pain and cough following laryngeal herpes zoster:A case report

BACKGROUND Herpes zoster is caused by reactivation of latent varicella-zoster virus infection within the sensory nerve ganglion of the spinal or cranial nerves.Laryngeal herpes zoster is rare and involves superior laryngeal nerve,which leads to several complications such as throat pain,and cough.CASE SUMMARY Patient concerns:A 52-year old woman presented with a 70 d history of throat pain and a 67 d history of non-productive cough.Three days after onset of pain,she was diagnosed with laryngeal herpes zoster.Flexible nasolaryngoscopy revealed multiple white ulcerated lesions on the left hemi epiglottis and the left supraglottic area.She was prescribed with 750 mg famciclovir a day for 7 d,and 150 mg pregabalin,100 mg tramadol and 10 mg nortriptyline a day for 67 d.However,despite of these medications,she complained of pain and persistent cough.Therefore,superior laryngeal nerve block under ultrasound guidance was performed.Three days after the intervention,the throat pain and cough disappeared.The patient remained symptom-free at 3 mo follow-up.CONCLUSION A superior laryngeal nerve block can be an effective option for treatment of pain and cough following laryngeal herpes zoster.

SRC:Superior Robustness of COVID-19 Detection from Noisy Cough Data Using GFCC

This research is focused on a highly effective and untapped feature called gammatone frequency cepstral coefficients(GFCC)for the detection of COVID-19 by using the nature-inspired meta-heuristic algorithm of deer hunting optimization and artificial neural network(DHO-ANN).The noisy crowdsourced cough datasets were collected from the public domain.This research work claimed that the GFCC yielded better results in terms of COVID-19 detection as compared to the widely used Mel-frequency cepstral coefficient in noisy crowdsourced speech corpora.The proposed algorithm's performance for detecting COVID-19 disease is rigorously validated using statistical measures,F1 score,confusion matrix,specificity,and sensitivity parameters.Besides,it is found that the proposed algorithm using GFCC performs well in terms of detecting the COVID-19 disease from the noisy crowdsourced cough dataset,COUGHVID.Moreover,the proposed algorithm and undertaken feature parameters have improved the detection of COVID-19 by 5%compared to the existing methods.

Characteristic metabolic and microbial profiles in acute ischemic stroke patients with phlegm-heat pattern

Objective:To explore the characteristics of plasma metabolites,feces gut microbiota and the crosstalk between gut microbiota and host metabolism in patients with acute ischemic stroke and phlegm-heat pattern(AIS-PHP).Methods:The metabolic and microbiome profiles of 20 AIS-PHP patients and 20 healthy controls(HCs)were analyzed using liquid chromatography-tandem mass spectrometry(LC-MS/MS)-based metabolomics and 16s rDNA sequencing,respectively.The covariation between LC-MS/MS-based metabolite data and 16s rDNA sequence data was presented.Results:Distinct alterations in the plasma metabolic phenotype of AIS-PHP patients were found,in which 16 metabolites differed significantly between the AIS-PHP patients and the HCs.These metabolites represented 17 different metabolic pathways,including amino acid metabolism,lipid metabolism,and nucleotide metabolism.Additionally,significant alterations of gut microbiota composition and taxon were revealed at the phylum level between the AIS-PHP patients and the HCs.In AIS-PHP,Bacteroidetes,Firmicutes,and Proteobacteria dominated.Moreover,some microbes that differed between the 2 groups manifested a sole association with certain metabolites,such as the connection between Bacteroides and inosine and between Lachnospiraceae_unclassified and hypoxanthine.Conclusion:The present study preliminarily investigated the metabolomic and gut microbiome characteristics of AIS-PHP patient indicators.The link between metabolic and microbial dysbiosis in AIS-PHP sheds new light on the function of gut microbiota and associated metabolomics in the pathogenesis of the disease.

A systemaic review and meta-analysis of traditional Chinese medicine in the treatment of chronic cough

Objective: To systematically evaluate the safety and efficacy of traditional Chinese medicine (TCM) in the treatment of chronic cough. Methods: Databases CNKI, WanFang Data, VIP, CBM, PubMed, Web of Science, Cochrane Library from inception to February 2021 were electronically searched by two researchers, to collect randomized controlled trials (RCTs) of traditional Chinese medicine in the treatment of chronic cough, UACS/PNDS, CVA, EB, AC, GERD and other types of cough. Revman 5.3 software was used to analyze and summarize the collected literature, and the methodological quality of the included studies was evaluated by the bias risk assessment scale of Cochrance Collaboration Network. Results: A total of 26 articles involving 2 820 patients, with 1 420 in the experimental group and 1 400 in the control group were included. The results of meta-analysis showed that compared to the control group which was treated with western medicine alone, TCM significantly improved the clinical effective rate [RR=1.20, 95% CI(1.16,1.25), P<0.000 01], alleviated cough syndrome score [SMD=-0.83, 95% CI(-1.21,-0.44)], and enhenced the score of quality of life [MD=-2.18, 95%CI(1.63,2.74), P<0.000 01];at the same time, the experimental group was better than the control group in improving lung function and reducing the time of cough relief. In terms of safety, a total of 24 patients in 5 literatures had adverse reactions, but the symptoms were mild and could be relieved quickly. In addition, there was no significant difference in adverse reactions between the control group and the experimental group, showing good safety. Conclusion: TCM treatment can significantly improve the cure rate of cough, reduce cough score, improve systemic symptoms, relieve psychological anxiety, improve lung function, and improve cough symptoms rapidly, with good safety.

从“阳化气,阴成形”探讨慢性咳嗽之因机证治

慢性咳嗽是以咳嗽为主症或唯一症状、病程持续8周以上的呼吸系统疾病。慢性咳嗽病因复杂,病程较长,病势缠绵,且极易复发。西医诊断该病过程繁琐,治疗手段有限,而中医药以整体观念和辨证论治思想为指导,在缓解临床症状、预防疾病复发方面具有独特优势。该文以“阳化气,阴成形”为抓手,分析阴阳在慢性咳嗽因机证治全周期的重要意义,认为慢性咳嗽之病机关键为“阳化气,阴成形”功能失衡,以肺之气血失和、阴阳虚损为本,阳化而气行不畅、周流有碍,阴变而凝结停滞、壅塞肺络为标。治疗上,需要补肺、脾、肾阴阳之不足,泄气滞、水湿、痰饮、瘀血、热毒之有余,以恢复“阳化气,阴成形”之平衡。具体用药方面,主张以偏纠偏,以药物气味之偏性纠正人体阴阳之偏颇。另附典型医案二例,加以验证说明,以期为中医药防治慢性咳嗽提供新的诊疗思路和方法。
