ObjectiveTo explore the mechanism of Jiebiao Qingli decoction （JQD） in treating pneumonia caused by influenza A virus （IAV） infection. MethodsA total of 132 Balb/c mice were randomly assigned into normal control （NC）， model control （IAV）， oseltamivir （OSV， 37.5 mg·kg^-1）， and high-， medium-， low-dose JQD （H-， M-， and L-JQD： 6.05， 3.02， and 1.51 g·kg^-1， respectively） groups. The NC group was treated with normal saline nasal drops， and the other groups were intranasally inoculated with A/Brisbane/02/2018 （H1N1） ［pdm09-like virus （H1N1）］ for the modeling of IAV infection. Two hours post-modeling， the NC and IAV groups were administrated with normal saline by gavage， while other groups received corresponding drugs for 7 d. The body mass， survival status， and deaths of mice were recorded daily during the administration of the drugs. On days 3 and 7， the lung index was measured for mice in each group. Pathological changes in the lung tissue were observed via hematoxylin-eosin staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was conducted to measure the viral load （IAV-M） and the mRNA levels of Toll-like receptor 7 （TLR7）， p38 mitogen-activated protein kinase （p38 MAPK）， and nuclear factor-kappa B （NF-κB） in the lung tissue. Western blot was employed to measure the protein levels of p38 MAPK and NF-κB. Enzyme-linked immunosorbent assay was used to quantify serum levels of interleukin-2 （IL-2）， interleukin-6 （IL-6）， and tumor necrosis factor-alpha （TNF-α）. ResultsCompared with the NC group， the IAV group showed reduced survival quality and survival days （P<0.01）， lung congestion， inflammatory cell infiltration， elevated lung index （P<0.01）， increased viral load （P<0.01）， upregulated TLR7， p38 MAPK， and NF-κB levels （P<0.05， P<0.01）， decreased IL-2 level （P<0.01）， and elevated IL-6 and TNF-α levels （P<0.01）. Compared with the IAV group， H-JQD prolonged survival days （P<0.05）. All JQD groups alleviated pathological changes in the lung tissue and reduced the lung index （P<0.01）. M-JQD and H-JQD decreased the viral load （P<0.01）. H-JQD downregulated the mRNA levels of TLR7， p38 MAPK， and NF-κB （P<0.05， P<0.01） and the protein levels of p38 MAPK and NF-κB （P<0.01）， increased the serum IL-2 level （P<0.01）， and lowered the IL-6 and TNF-α levels （P<0.05， P<0.01）. M-JQD downregulated the mRNA level of NF-κB （P<0.01） and the protein level of p38 MAPK （P<0.05）， elevated the IL-2 level （P<0.01）， and lowered the TNF-α level （P<0.01）. ConclusionM- and H-JQD can prevent and control IAV infection-induced pneumonia dose-dependently by inhibiting the TLR7/MAPK/NF-κB signaling pathway， increasing IL-2， and reducing excessive secretion of IL-6 and TNF-α.

As an exclusive Miao medicine of Honwing Pharma （Guizhou） Co. Ltd.， Yifei Zhike capsules are both a prescription drug and an over-the-counter （OTC） drug. Its main ingredients include Ranunculus ternatus and Panax notoginseng. With the effects of nourishing Yin and moistening the lungs， as well as relieving cough and reducing phlegm， Yifei Zhike capsules are often used in the treatment of acute and chronic bronchitis， pulmonary tuberculosis， and other diseases. However， there is insufficient understanding of their efficacy， suitable syndromes， and safety in clinical practice， with a lack of relevant expert consensus on clinical application. To standardize their clinical application， 30 experts from the fields of respiratory medicine， pharmacy， and evidence-based medicine were invited to develop an Expert Consensus on the Clinical Application of Yifei Zhike Capsules （Consensus for short） through evidence-based medicine methods. The Consensus clarified the syndrome characteristics， disease stages， dosages， treatment courses， combined medication， and other norms in the treatment of acute/chronic bronchitis and pulmonary tuberculosis and could be applicable to clinical physicians and pharmacists in medical and health institutions at all levels. In disease diagnosis， it provided diagnostic criteria for traditional Chinese medicine and Western medicine and clarified that the suitable traditional Chinese medicine syndrome was the syndrome of Qi-Yin deficiency with intermingled phlegm-blood stasis. Clinical studies have confirmed that Yifei Zhike capsules combined with standard anti-tuberculosis therapy can effectively improve the symptoms of pulmonary tuberculosis patients， increase the sputum smear conversion rate， and promote the absorption of lesions. When treating acute cough caused by respiratory tract infections， Yifei Zhike capsules can increase the markedly effective rate and the seven-day disappearance rate of cough symptoms. Meanwhile， recommendations for specific usage， dosages， and treatment courses were given for different diseases， and it was pointed out that long-term medication required key monitoring of adverse reactions. In safety， the adverse reactions of Yifei Zhike capsules involved multiple aspects such as the digestive system and allergic reactions， and pregnant women and women during menstruation were prohibited from using it. In addition， modern research has shown that Yifei Zhike capsules have an adjuvant therapeutic effect on tuberculous pleurisy and may be effective for inflammatory and benign pulmonary nodules. However， further research should be conducted on the toxicological safety of long-term medication. The formulation of the Consensus provides a scientific basis for the rational clinical application of Yifei Zhike capsules， which helps to improve clinical efficacy and reduce medication risks.

ObjectiveThis study aimed to evaluate the clinical effectiveness and safety of Guben Kechuan Granules （固本咳喘颗粒） in treating chronic bronchitis （CB） with lung qi weakness pattern. MethodsA multicenter， randomized controlled trial was conducted， and 180 patients with CB of lung qi weakness pattern were randomly divided into 120 cases in the treatment group and 60 cases in the control group according to a 2∶1 ratio. The control group received health education for 24 weeks， while conventional symptomatic treatment was given when acute exacerbation of CB occurred. Treatment group was treated with the oral administration of Guben Kechuan Granules， 2 g each time， 3 times a day， for a total of 24 weeks on the basis of treatment of the control group. Both groups were followed up for 24 weeks after 24 weeks of treatment. Primary effectiveness indicators included the number of CB acute exacerbations occurence during the treatment and follow-up period， and the total number of CB acute exacerbations from the start of treatment to the end of follow-up. Secondary effectiveness indicators included the details of CB acute exacerbations， i.e.， time to first acute exacerbation， time between acute exacerbations， duration of each time of acute exacerbation， and acute exacerbation symptom severity scores， and lung function indices. The scores of cough， sputum， and wheeze and total symptom scores were compared prior to treatment， at 4， 8， 12， 16， 20， and 24 weeks of treatment， and at 24 weeks of follow-up. The occurrence of adverse events during the study period was recorded and safety indices including blood routine， liver function， kidney function， and urine routine were tested. ResultsA total of 179 participants completed the trial including 119 in the treatment group and 60 in the control group. Compared to pre-treatment scores within the group， the treatment group showed reductions in cough， sputum， and wheeze scores， and total symptom scores at weeks 4， 8， 12， 16， 20， and 24 of treatment， as well as at 24 weeks of follow-up； in the control group， cough scores decreased at weeks 16， 20， and 24， sputum and wheeze scores decreased at week 24 of treatment and at 24 weeks of follow-up， and total symptom scores decreased at weeks 20， 24 of treatment， and at 24 weeks of follow-up （P＜0.05）. Compared with the control group， the treatment group showed reductions in the number of CB acute exacerbations occurence during the treatment and follow-up period， and the total number of CB acute exacerbations from the start of treatment to the end of follow-up， the duration of acute exacerbations， the acute exacerbation symptom severity scores， and the scores for cough， sputum， wheeze， and total symptoms at weeks 8， 12， 16， 20， 24 of treatment， and at 24 weeks of follow-up； while the time to the first acute exacerbation of CB was significantly prolonged in the treatment group （P＜0.05 or P＜0.01）. There were no statistically significant differences in lung function indicators between groups before treatment and at 24 weeks after treatment （P＞0.05）. Safety indicators showed no significant abnormalities before or after treatment in either group， and the incidence of adverse events during the treatment period showed no significant differences between the groups （P＞0.05）. ConclusionGuben Kechuan Granules can reduce the risk of acute exacerbations in CB patients with lung qi weakness pattern， improve clinical symptoms such as cough， sputum， and wheeze， and show good safety.

To summarise the clinical experience of Professor CHAO Enxiang in treating idiopathic pulmonary hemosiderosis （IPH） by staging from heat， phlegm， stasis and deficiency. It is believed that IPH has blood-heat and phlegm-stasis， and deficiency of qi and yin as the core pathomechanisms， in which the pathomechanism of acute pulmonary haemorrhage is based on intense blood heat， and modified Shihui Powder （十灰散） is used to clear heat and regulate ying qi （nutrient qi）， and reduce fire to settle the collaterals. The pathomechanism of pulmonary haemorrhage in the static stage is based on phlegm-heat obstructing the lungs， and modified Qingfei Dingke Decoction （清肺定咳汤） is used to clear the lungs and dissolve phlegm， harmonize the collaterals to stop haemorrhage. The pathomechanism of acute exacerbation at chronic stage is based on deficiency of qi and yin， and also blood-heat and phlegm-stasis， modified Shengmai Powder （生脉散）， Shihui Powder plus Qingfei Dingke Decoction should be used to benefit qi and nourish yin， clear heat， resolve phlegm and eliminate blood stasis. In the chronic prolongation period， the pathogenesis of the disease is based on the deficiency of qi and yin， modified Shengmai Powder may be used to benefit qi and nourish yin， moisten the lungs and rest blood.

The compilation instructions for the Expert Consensus on Clinical Application of Yifei Zhike Capsules systematically expound the development background， methodological framework， and core achievements of this consensus. In view of the problems existing in the clinical application of Yifei Zhike Capsules， such as insufficient efficacy evidence and lack of standardized syndrome differentiation， the Institute of Basic Research in Clinical Medicine， China Academy of Chinese Medical Sciences took the lead and collaborated with 21 tertiary grade-A hospitals and research institutions across China to form a multidisciplinary expert group （comprising 30 experts in clinical medicine， pharmacy， and methodology）. The compilation work was carried out in strict accordance with the World Health Organization （WHO） guidelines， the GB/T 1.1-2020 standard， and the writing specifications for the explanatory notes of expert consensus on clinical application of Chinese patent medicines. Through systematic literature retrieval （including 32 studies， with 24 clinical studies）， Grading of Recommendations Assessment， Development and Evaluations （GRADE）-based evidence grading， and multiple rounds of discussions using the nominal group method （25 experts voted to determine 17 clinical questions）， 5 evidence-based recommendations and 11 expert consensus suggestions were formed. It is clarified that this medicine （Yifei Zhike Capsules） is applicable to the treatment of expectoration/hemoptysis in acute and chronic bronchitis and the adjuvant treatment of pulmonary tuberculosis. It is recommended that it can be used alone or in combination with anti-tuberculosis drugs. The safety evaluation shows that this medicine mainly induces the following adverse reactions： mild gastrointestinal reactions （such as nausea and abdominal pain） and rashes. The contraindicated populations include pregnant women and women during menstruation. The compilation process of the consensus underwent three rounds of expert letter reviews， two rounds of peer reviews， and quality control assessments to ensure methodological rigor and clinical applicability. In addition， through policy alignment， academic promotion， and a dynamic revision mechanism， the standardization of clinical application was promoted， providing a demonstration for the evidence-based transformation of characteristic therapies of Miao medicine.

Objective:To evaluate the efficacy of visualized precise lung expansion for determining the intersegmental plane in thoracoscopic segmentectomy.Methods:Sixty-four American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, regardless of gender, aged 33-77 yr, with body mass index of 16-34 kg/m 2, undergoing elective thoracoscopic segmentectomy under general anesthesia, were included. They were preoperatively reconstructed with 3D CT bronchovascularization to reconstruct the pulmonary vasculature, bronchus, and the virtual intersegmental planes of the lungs. The patients were divided into 2 groups ( n=32 each) using a random number table method: visualized precise lung expansion group (group V) and modified expansion and atrophy group (group E). Group V used visualized precision lung expansion to determine the intersegmental planes, and group E used the modified expansion and atrophy method to determine the intersegmental planes. The intraoperative intersegmental plane determination time, target segmental bronchus identification and treatment time, anesthesia time, operation time, postoperative air leakage, pulmonary atelectasis, fever, occurrence of lung infection, postoperative 24 h drainage volume, drain removal time and hospitalization time were recorded in the two groups. Results:Compared with group E, the intersegmental plane determination time, target segment bronchial identification and treatment time, anesthesia time and operation time were significantly shortened in group V( P<0.05).There were no significant differences between groups in the 24 h postoperative drainage volume, drain removal time, hospitalization time or incidence of postoperative pulmonary complications ( P>0.05). Conclusions:Compared with the modified expansion and atrophy method, visualized precise lung expansion can effectively shorten the intersegmental plane determination time in thoracoscopic segmentectomy.

Objective To investigate the relationship between cognitive impairment and sleep parameters in acute ischemic stroke patients with obstructive sleep apnea(OSA).Methods A total of 343 patients with acute ischemic stroke and OSA were selected.The cognitive function was assessed using the simple mental state examination scale(MMSE).Patients were divided into the stroke with OSA and cognitive impairment group(MMSE＜27 points,n=119)and the stroke with OSA without cognitive impairment group(MMSE≥27 points,n=224).General data,TOAST etiological classification and distribution of cerebral infarction lesions were collected.The intelligent sleep monitoring system was used to calculate apnea hypopnea index(AHI)and evaluate OSA.Objective sleep monitoring parameters were collected at night.Sleep monitoring was conducted within 24 h of admission and continuous monitoring for≥3 nights.Continuous monitoring duration≥7 h every night to obtain night sleep structure parameters.Multifactor Logistics regression was used to analyze the relationship between cognitive impairment and sleep parameters in stroke patients with OSA.Results Compared with the stroke with OSA without cognitive impairment group,the proportion of age,diabetes history and HHcy history,the proportion of patients with infarct lesions located in frontal,temporal,parietal,occipital,thalamus,basal ganglia,brainstem and hemioval center increased in the stroke with OSA and cognitive impairment group,and the number of years of education decreased,the number of waking times,the proportion of light sleep and AHI increased,the nighttime sleep efficiency and deep sleep period decreased(P＜0.05).Logistics regression analysis showed that after controlling for years of education,age and other interference factors,nighttime sleep efficiency and AHI were strongly associated with cognitive impairment in acute ischemic stroke patients with OSA(P＜0.05).The increased nighttime sleep efficiency was protective factor for cognitive impairment,and increased AHI was risk factor for cognitive impairment.Conclusion Cognitive impairment in acute ischemic stroke patients with OSA is closely related to sleep parameters,in which the increased sleep efficiency at night is a protective factor for cognitive impairment,and the increased AHI is a risk factor.
