OBJECTIVES: To study the efficacy and safety of Xiyanping injection through intramuscular injection for the treatment of acute bronchitis in children. METHODS: A prospective study was conducted from December 2021 to October 2022, including 78 children with acute bronchitis from three hospitals using a multicenter, randomized, parallel-controlled design. The participants were divided into a test group (conventional treatment plus Xiyanping injection; n=36) and a control group (conventional treatment alone; n=37) in a 1:1 ratio. Xiyanping injection was administered at a dose of 0.3 mL/(kg·d) (total daily dose ≤8 mL), twice daily via intramuscular injection, with a treatment duration of ≤4 days and a follow-up period of 7 days. The treatment efficacy and safety were compared between the two groups. RESULTS: The total effective rate on the 3rd day after treatment in the test group was significantly higher than that in the control group (P<0.05), while there was no significant difference in the total effective rate on the 5th day between the two groups (P>0.05). The rates of fever relief, cough relief, and lung rale relief in the test group on the 3rd day after treatment were higher than those in the control group (P<0.05). The cough relief rate on the 5th day after treatment in the test group was higher than that in the control group (P<0.05), while there was no significant difference in the fever relief rate and lung rale relief rate between the two groups (P>0.05). The cough relief time, daily cough relief time, and nocturnal cough relief time in the test group were significantly shorter than those in the control group (P<0.05), while there were no significant differences in the fever duration and lung rale relief time between the two groups (P>0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05). CONCLUSIONS The overall efficacy of combined routine treatment with intramuscular injection of Xiyanping injection in the treatment of acute bronchitis in children is superior to that of routine treatment alone, without an increase in the incidence of adverse reactions.

The aim of this paper was to investigate the preventive and therapeutic effects of Xiaoer Feike Granules(XEFK) on chronic bronchitis in rats and its mechanism. Except for 10 rats in the blank group, the remaining 50 of the 60 SD rats were used to establish a model of chronic bronchitis induced by LPS. On the 22 nd day, the model rats were randomly divided into 5 groups according to their body weight, and administrated with purified water, Keteling Capsules 0.11 g·kg~(-1), XEFK 3.2, 1.6 and 0.8 g·kg~(-1)(the dosing concentrations were 0.32, 0.16, 0.08 g·mL~(-1), respectively). These rats took the corresponding drug orally once a day, for consecutive 21 days. The rats were anesthetized 1 hour after the last administration, and the lavage bronchus and alveoli were collected. Then, after the fixation of the smear, neutrophils were counted microscopically, and the contents of glutathione peroxidase(GSH-Px), superoxide dismutase(SOD) and malondialdehyde(MDA) in the bronchoalveolar lavage fluid(BALF) were detected by colorimetric method. Flow cytometry was used to detect the content changes of T cell subsets CD4~+, CD8~+, CD4~+/CD8~(+ )in serum. Hemorheology related indexes were detected by automatic hemorheology. Enzyme-linked immunosorbent assay(ELISA) was used to detect the contents of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), IL-2, IL-6 and IL-10 in serum. The expression of TNF-α and IL-10 mRNA in lung was detected by Real-time quantitative PCR(RT-qPCR). HE staining was used to observe the pathological changes in the bronchitis tissues. Compared with the model group, XEFK high and medium dose groups could significantly reduce the contents of neutrophils and MDA in bronchial lavage fluid, and increase the activities of GSH-Px and SOD in BALF, and repair the chronic inflammatory cell infiltration and lymphoid tissue hyperplasia in the bronchial mucosal layer and submucosal layer. The high-dose group could reduce the plasma viscosity of rats, but there was no statistical difference in other hemorheological indexes. CD4~+, CD8~+, CD4~+/CD8~+, IL-2 and IL-10 contents in each dose group were significantly increased, and TNF-α, IL-1β and IL-6 contents were significantly decreased in serum. Each dose group could significantly down-regulate the expression level of TNF-α mRNA in the lung and increase the expression of IL-10 mRNA. XEFK could reduce lipid peroxidation, increase the content of peripheral blood T cell subsets, regulate the release and secretion of inflammatory factors, and repair the morphological and pathological changes of bronchial tissue. Its mechanism might be related to the improvement of inflammatory response and the enhancement of immune function.

To evaluate the effectiveness and safety of Xiyanping Injection in the treatment of acute bronchitis in children. The research systematically retrieved four Chinese databases( namely CNKI,VIP,Wan Fang,Sino Med) and four English databases( namely EMbase,Cochrane Library,Medline,Clinical Trail.gov). The retrieval time ranged from the commencement of each database to April2019. According to pre-set inclusion criteria and exclusion criteria,randomized controlled trials( RCTs) of Xiyanping Injection in the treatment of acute bronchitis in children were screened out. The quality assessment of the included studies was performed using the " Cochrane Bias Risk Assessment" tool,and the Meta-quantitatively analysis on the included studies was performed using Rev Man 5.3 software. A total of 648 articles were retrieved,and 10 studies were finally included. Except for one multi-arm test,the total sample size was 1 260,including 630 cases in the test group and 630 cases in the control group. The overall quality of the included study was not high. The results of Meta-analysis showed that in terms of antipyretic time,Xiyanping Injection combined with routine therapy was superior to routine therapy in the shortening of fever time in children with acute bronchitis( MD =-0.94,95%CI[-1.18,-0.70],P<0.000 01); in the overall efficacy,Xiyanping Injection combined with routine therapy was superior to routine therapy( RR = 1. 34,95% CI[1.26,1.42],P<0.000 01) and Yanhuning Injection + routine therapy( RR = 1.28,95%CI[1.19,1.38],P<0.000 01); descriptive analysis showed that Xiyanping Injection was excellent in the overall efficacy in treating acute bronchitis in children. The differences between the two groups were statistically significant( P< 0.000 1). The adverse reactions included in the study were mild adverse reactions,with no impact on treatment. Based on the results of this study,Xiyanping Injection combined with routine therapy or other Western medicine had a certain effect on acute bronchitis in children,especially in improving the overall efficacy of acute bronchitis in children. No serious adverse reactions were observed. And in the time of fever,cough and cough disappearance time,lung voice loss time,Xiyanping Injection + routine therapy or Western medicine therapy was better than routine therapy or Western medicine therapy. However,the small size of included studies,the low quality of the included studies,and the existence of publication bias and the low quality of the evidence had impacts on the reliability of the conclusion. Therefore,more large-sample,multi-center,well-designed,rigorous randomized controlled trials with best case reports are required to further verify the efficacy and safety.

To systematically review the effectiveness and safety of Reduning Injection in the treatment of acute tracheal-bronchitis.Four Chinese databases( CNKI,VIP,Wan Fang,Sino Med) and three English databases( Cochrane Library,Medline,Web of Science) were systematically and comprehensively retrieved. The retrieval time was from the establishment of each database to April 2019.Randomized controlled trials( RCTs) for the treatment of acute tracheal-bronchitis with Reduning Injection were collected. Two researchers independently conducted literature screening,data extraction and risk assessment for bias. Rev Man 5.3 software was used for data analysis. Fourteen studies were included,and the total sample size was 1 652 at last. Meta-analysis results show that in the aspect of total clinical effective rate,Reduning Injection was superior to ribavirin( RR = 1. 37,95%CI[1. 28,1. 47],P<0. 000 01); Reduning Injection combined with conventional therapy was better than conventional therapy alone( RR = 1. 14,95% CI[1. 09,1. 19],P <0. 000 01); Reduning Injection combined with azithromycin was better than azithromycin therapy alone( RR = 1. 21,95% CI[1. 07,1. 37],P = 0. 002). In the aspect of clinical symptoms,the time in average fever disappearance of Reduning Injection therapy was shorter than that of ribavirin therapy( MD =-1.68,95%CI[-1. 72,-1. 49],P<0. 000 01); the time in cough disappearance of Reduning Injection therapy was shorter than that of ribavirin therapy( MD =-2. 57,95%CI[-2. 91,-2. 24],P<0. 000 01); the time in lung rales disappearance,Reduning Injection therapy was superior to ribavirin therapy( MD =-2. 26,95% CI[-2. 71,-1. 80],P<0. 000 01),and Reduning Injection combined with conventional therapy was superior to conventional therapy( MD =-1. 77,95% CI[-1. 95,-1. 59],P<0. 000 01). Based on the findings,Reduning Injection can improve the total effective rate,reduce the average time of disappearance in fever,cough and lung rales,with mild adverse reactions and a low incidence. However,the quality of the literatures included is not high,it is necessary to adopt large-sample-size,rigorously designed clinical trial protocols in line with the international standards,in a bid to improve the quality of evidence.

To systematically review the effectiveness and safety of Tanreqing Injection in treating acute exacerbation of chronic bronchitis( AECB). CNKI,Wan Fang,VIP,CBM,Medline,Cochrane Library,EMbase and Web of Science were retrieved,and randomized controlled trials for the effect of Tanreqing Injection in the treatment of acute exacerbation of chronic bronchitis were screened. The quality of the included studies was evaluated according to the Cochrane Handbook's evaluation criteria. The data was analyzed by RevMan 5.3. Totally 23 RCTs involving 1 901 patients were included,including 952 in the experimental group and 949 in the control group. The Meta-analysis demonstrated that in terms of the disappearance time of fever,the group of Tanreqing Injection combined with the conventional therapy was superior to conventional therapy group( RR =-1. 03,95%CI[-1. 45,-0. 62],P<0. 000 01); compared with the conventional therapy group,the group of Tanreqing Injection combined with conventional therapy had a higher cure rate for AECB( RR = 1. 17,95% CI[1. 13,1. 23],P < 0. 000 01). The group of Tanreqing Injection combined with levofloxacin had a higher cure rate for AECB than the levofloxacin group( RR = 1. 23,95% CI[1. 08,1. 41],P = 0. 002). The group of Tanreqing Injection combined with cefuroxime had a higher cure rate for AECB than the cefuroxime group( RR = 1. 22,95%CI[1. 05,1. 42],P = 0. 01).The group of Tanreqing Injection combined with cefoperazone sodium and sulbactam sodium had a higher cure rate for AECB than the group of cefoperazone sodium and sulbactam sodium( RR = 1. 22,95% CI[1. 04,1. 44],P = 0. 02). The outcomes of disappearance time of cough and expectoration had a huge heterogeneity,so were used for descriptive analysis. The adverse reactions mainly included skin rash,dizziness,gastrointestinal reactions. Based on the available data and the results of the analysis,the group of Tanreqing Injection combined with Western medicine has a higher cure rate for acute exacerbation of chronic bronchitis,and the effect in reducing symptoms disappearance time. In view of the limited number of included studies,small sample size and low methodological quality,the results of this study need to be confirmed with high-level clinical trials.

BACKGROUNDThe efficacy of montelukast (MONT), a cysteinyl leukotriene receptor antagonist, in nonasthmatic eosinophilic bronchitis (NAEB), especially its influence on cough associated life quality is still indefinite. We evaluated the efficacy of MONT combined with budesonide (BUD) as compared to BUD monotherapy in improving life quality, suppressing airway eosinophilia and cough remission in NAEB.

METHODSA prospective, open-labeled, multicenter, randomized controlled trial was conducted. Patients with NAEB (aged 18-75 years) were randomized to inhaled BUD (200 μg, bid) or BUD plus oral MONT (10 μg, qn) for 4 weeks. Leicester cough questionnaire (LCQ) life quality scores, cough visual analog scale (CVAS) scores, eosinophil differential ratio (Eos), and eosinophil cationic protein (ECP) in induced sputum were monitored and compared.

RESULTSThe control and MONT groups contained 33 and 32 patients, respectively, with similar baseline characteristics. Significant with-in group improvement in CVAS, LCQ scores, Eos, and ECP was observed in both groups during treatment. After 2-week treatment, add-on treatment of MONT was significantly more effective than BUD monotherapy for CVAS decrease and LCQ scores improvement (both P < 0.05). Similar results were seen at 4-week assessment (both P < 0.05). 4-week add-on therapy of MONT also resulted in a higher percentage of patients with normal sputum Eos (<2.5%) and greater decrease of ECP (both P < 0.05).

CONCLUSIONSMONT combined with BUD was demonstrated cooperative effects in improvement of life quality, suppression of eosinophilic inflammation, and cough remission in patients with NAEB.

The role of atypical bacteria and the effect of antibiotic treatments in acute bronchitis are still not clear. This study was conducted at 22 hospitals (17 primary care clinics and 5 university hospitals) in Korea. Outpatients (aged > or = 18 yr) who had an acute illness with a new cough and sputum (< or = 30 days) were enrolled in 2013. Multiplex real-time polymerase chain reaction (RT-PCR) was used to detect five atypical bacteria. A total of 435 patients were diagnosed as having acute bronchitis (vs. probable pneumonia, n = 75), and 1.8% (n = 8) were positive for atypical pathogens (Bordetella pertussis, n = 3; B. parapertussis, n = 0; Mycoplasma pneumoniae, n = 1; Chlamydophila pneumoniae, n = 3; Legionella pneumophila, n = 1). Among clinical symptoms and signs, only post-tussive vomiting was more frequent in patients with atypical pathogens than those without (P = 0.024). In all, 72.2% of the enrolled patients received antibiotic treatment at their first visits, and beta-lactams (29.4%) and quinolones (20.5%) were the most commonly prescribed agents. In conclusion, our study demonstrates that the incidence of atypical pathogens is low in patients with acute bronchitis, and the rate of antibiotic prescriptions is high.

OBJECTIVETo analyze the clinical characteristics of protracted bacterial bronchitis (PBB) in children.

METHODThe clinical data of patients seen from October, 2010 to March, 2014 in Department of Respiratory Diseases of our hospital were retrospectively analyzed. Inclusion criteria were over 4 weeks cough, receiving fiberoptic bronchoscopy, positive bacterial culture and (or) the increased percentage of neutral granulocytes in bronchoalveolar lavage fluid (BALF).

RESULTTwenty eight patients were involved, 26 were male (93%) and two were female (7%). The median age of patients was 8.5 months. The median duration of cough was four weeks. The average length of hospital stay was (8.3 ± 3.9)days. The main clinical feature was wet cough in 28 cases, wet cough with wheezing was seen in 21 cases. The wet cough phase distribution was irregular in 21 cases. The crackles with wheeze (in 21 cases) was main signs of PBB. The percentage of CD3⁻ CD16⁺ 56⁺ cells increased in peripheral blood. The fiberoptic bronchoscopic manifestations of PBB were luminal mucosal edema. Eleven patients also had airway malacia. The neutrophil median in BALF was 0.2. The positive rate of bacterial culture of BALF was 36%. The main bacteria were Streptococcus pneumoniae (50%) and Haemophilus influenzae (30%). The main treatment for PBB patients included amoxycillin/clavulanate potassium and second-generation cephalosporins. The average duration of treatment was (17.3 ± 3.2)days, the prognosis was good.

CONCLUSIONPBB is common in male infants. Persistent wet cough with wheezing was the main characteristic of PBB. PBB is commonly accompanied by immune dysfunction and airway malacia, and the pathogens were Streptococcus pneumoniae and Haemophilus influenzae.

OBJECTIVETo study the clinical features and pathogens of plastic bronchitis in children.

METHODSA retrospective analysis was performed on the clinical data of 9 children who were diagnosed with plastic bronchitis between January 2011 and December 2012.

RESULTSPlastic bronchitis began with a fever and cough in all cases, followed by progressive dyspnea on days 1-3 of onset; unilateral or bilateral decreased breath sounds and hepatosplenomegaly were found; complications included respiratory failure (6 cases), toxic encephalopathy (6 cases), toxic hepatitis (7 cases), shock (3 cases), heart failure (3 cases), and renal failure (2 cases). Chest X-ray or chest CT showed single and multiple lobar or segmental consolidation and atelectasis, as well as pleural effusion (4 cases). The bronchofibroscopy revealed some grey-white mucus plugs that blocked bronchial openings and aspirates of bronchial shape. Influenza viruses (IFVs) were detected in all cases, including IFV-A (6 cases, 67%) and IFV-B (3 cases, 33%). Mixed infection with IFV-A and Mycoplasma pneumoniae (MP)/bacteria was found in 50% of all cases. In the three cases of IFV-B infection, one was complicated by MP infection. Nine patients were given treatment of antibiotics, hormones, gamma globulin and necessary respiratory support, and also were given removal of endogenous foreign body by bronchoscopy. Five patients were given antiviral therapy of oseltamivir. Seven cases cured, and 2 died.

CONCLUSIONSPlastic bronchitis and severe pneumonia are similar in clinical manifestations. IFVs are the main pathogen. In addition to anti-infection treatment, hormone, gamma globulin, respiratory support, and other conventional treatments, endogenous foreign body removal by bronchofibroscopy and early antiviral therapy with oseltamivir have good efficacy.

OBJECTIVETo investigate the anti-inflammatory and immunoregulatory effects of Yupingfeng (, YPF) Powder and its components in rats.

METHODSA rat chronic bronchitis (CB) model was developed using lipopolysaccharide (LPS) combined with bacillus Calmette Guerin (BCG). YPF, simple recipe Astragalus membranaceus (Fisch.) Bge (AM) and Astragalus membranaceus (Fisch.) Bge plus rhizome of Atractylodes macrocephala Koidz (AM+RA) decoction were administered (intragastric administration, once a day for 21 days) to rats, to prevent and treat CB. Immunoregulatory and anti-inflammatory effects of YPF, AM and AM+RA were tested by serum pharmacology in vitro on splenic lymphocytes of normal rats and alveolar macrophages of CB rats.

RESULTSInflammation in the pulmonary tissue and the bronchus of CB rats was significantly reduced in the YPF-treatment groups, AM and AM+RA groups demonstrating the efficacy of YPF. Serum samples collected at different times from rats after administration of YPF, AM and AM+RA demonstrated increased proliferation of splenic lymphocytes with area under the effect curve (AUE) of 552.6%, 336.3% and 452.0%, respectively. Treatment of alveolar macrophages with serum samples in YPF, AM or AM+RA group inhibited interleukin-8 (IL-8) in the cell culture media, and the effect was much better in the YPF group compared with AM or AM+RA group, with a higher maximal effect (Emax, P<0.05) and larger AUE (P <0.01 and P<0.05). Moreover, serum from rats treated with AM or AM+RA had similar efficacy, while the efficiency was lower than that treated with YPF.

CONCLUSIONYPF demonstrated anti-inflammatory and immunoregulatory effects in a rat model of CB, and timedependent relationships were demonstrated in vitro.
