Abstract
Bronchial asthma (BA) is a chronic respiratory disease closely related to immune system dysregulation. Traditional Chinese medicine has long adopted the strategy of Sanao decoction in the treatment of bronchial asthma. However, due to the multi-target and multi-pathway characteristics of Chinese herbal medicine, we are still unclear about the specific mechanism of Sanao decoction in treating bronchial asthma. To investigate the mechanism of action of Sanao decoction in the treatment of BA using a network pharmacology approach and preliminary validation by molecular docking technology. Traditional Chinese medicine systems pharmacology database and analysis platform and UniProt databases were used to search the active ingredients and targets of Sanao decoction, and BA-related targets were screened according to GeneCards and online Mendelian inheritance in man database databases. The intersection targets were imported into the STRING database to construct a protein-protein interaction network, and Cytoscape 3.9.1 software was used to screen out hub genes. This study also constructed a "drug-ingredient-target" visual network diagram. Gene Ontology and Kyoto Encyclopedia of Genomes enrichment analysis was performed on targets in the protein-protein interaction network using the ClusterProfiler package in R, with a P value < .05. Autodock software was used for molecular docking to complete the preliminary verification of core components and targets. A total of 73 active compounds and 308 targets of Sanao decoction, including 1640 BA-related disease targets, were retrieved from mainstream databases. Gene Ontology analysis and Kyoto encyclopedia of genes and genomes enrichment analysis suggested that Sanao decoction plays a role in the treatment of BA through signaling pathways such as PI3K-Akt, MAPK, and IL-17 signaling pathway. The 9 core goals represent the main elements related to Sanao decoction in the treatment of BA. Subsequently, the molecular docking results showed that most of the active compounds of Sanao decoction have strong binding efficiency with the hub gene. Sanao decoction has a key impact on BA through multiple channels. In summary, this intricate network reflects the potential of Sanao decoction in treating BA, a multifactorial disease. In addition, this study laid the foundation for further in vivo and in vitro experimental research and expanded the clinical application of Sanao decoction.

Abstract
INTRODUCTION While the screening of chronic obstructive lung diseases (COPD, asthma, etc.) constitutes a major public health issue in France and worldwide, simple spirometry appears currently as the key to meeting the challenge. Since description of the forced expiratory maneuver by Robert Tiffeneau in 1947, it has been admitted that the FEV1/VC ratio permits diagnosis obstructive pulmonary diseases. However, the diagnostic criteria for this ratio remain uncertain. The long-lasting debate between advocates of a 0.7 "fixed ratio" (FR) of 0.7 and advocates of the "lower limit of normal" (LLN) remains relevant. STATE OF THE ARTS In this general review, we describe the respective advantages of the FR and LLN criteria according to the most recently published studies, and characterize the conditions associated with discrepancies between these criteria. PERSPECTIVES AND CONCLUSIONS FR and LLN appear not to share similar diagnosis values and the use of both criteria facilitates proposal of an up-to-date interpretation and diagnosis strategy in the context of first-line spirometry, particularly for patients with FEV1/VC ratio in the "grey zone".

Abstract
Pig bronchi are rare anomalies in which the right upper lobe bronchus originates above the carina. During surgery this can lead to technical challenges associated with the bronchial anastomosis, especially during lung transplantation. We herein report the case of a combined liver-lung transplantation with a pig bronchus in both the organ donor and transplant recipient. In both cases the bronchi originated slightly above the level of the carina facilitating an oblique resection and a single tracheobronchial anastomosis with a running suture. Follow-up bronchoscopy showed a completely healed anastomosis with no evidence of malacia or stenosis.

Abstract
We report a case of congenital bronchial atresia resected by the uniportal thoracoscopic approach. A man in his 20s with congenital bronchial atresia diagnosed at 16 years of age visited our hospital with gradually worsening shortness of breath. Chest computed tomography revealed a localized emphysematous area that progressively increased in size, in the left upper lobe and the absence of a left upper division bronchus with mucoid impaction. Surgical treatment was deemed necessary in view of dyspnea and progressively worsening emphysema, and the resection of left upper division was performed by uniportal video-assisted thoracoscopic surgery.

Pleurodesis After Bronchial Occlusion for Inoperable Secondary Spontaneous Pneumothorax. J Bronchology Interv Pulmonol 2021; 28:290-295.

Abstract
BACKGROUND In many cases of secondary spontaneous pneumothorax (SSP), surgery is not feasible. Furthermore, in cases with a collapsed lung or numerous air leaks, pleurodesis is ineffective, and treatment options are severely limited. For these cases, bronchial occlusion might be the only effective treatment, despite the low success rate. If, however, bronchial occlusion can expand the lung and reduce air leakage, it can positively amplify later effects on pleurodesis, resulting in a powerful treatment. We reviewed the clinical data of patients who underwent bronchial occlusion with endobronchial Watanabe spigot (BO-EWS) and pleurodesis to investigate the usefulness of bronchial occlusion therapy in inoperable SSP patients. MATERIALS AND METHODS This single-center, retrospective study reviewed 36 cases of inoperable SSP patients who underwent pleurodesis after BO-EWS from April 2007 to October 2018. Twenty cases were allocated to the air leak analysis group, and 16 cases were included in the pneumothorax volume analysis group. The Robert David Cerfolio classification and the Collins method were used to evaluate air leak and pneumothorax volume, respectively. RESULTS Pneumothorax volumes decreased significantly after BO-EWS from 29.1%±17.3% to 12.1%±8.8%, while the air leak score decreased from 2.9±1.4 to 1.2±1.0. The success rate for chest tube removals in cases that underwent pleurodesis after BO-EWS was 85.0% (17/20). CONCLUSIONS This study demonstrated the synergistic effectiveness of BO-EWS and the usefulness of pleurodesis treatment in inoperable SSP patients with lung collapse or numerous air leaks. We believe that this treatment will benefit patients with inoperable SSP which, until now, has had few treatment options.

Abstract
This paper discusses the basic thoughts behind the so-called diagnosis of COPD in relation to cause and course of the disease and questions the value of this functional defined terminology. Instead, the terminology should be based on morphology in the broadest sense including all methods suitable to describe pathological processes to understand the cause of bronchial diseases. The diagnosis COPD is only helpful in relation to therapeutic measures.

Abstract
Massive pulmonary hemorrhage, although rare, is a potentially life-threatening complications during heart surgery. We herein present 1 such case successfully treated by selective bronchial occlusion using an Endobronchial Watanabe Spigot (EWS). The 82-year-old female underwent mitral valve replacement, tricuspid annuloplasty, and maze procedure. An hour and a half after cessation of cardiopulmonary bypass, the patient suffered a massive pulmonary hemorrhage. A subsequent bronchoscopy identified the hemorrhage site at the right middle lobe bronchus (B5b), and an EWS was then selectively deployed into this bronchus to block the hemorrhage. The following day, bronchial arterial embolization was performed, enabling the removal of the spigot on the next day. The patient's respiratory condition gradually improved, allowing for extubation on the 21st postoperative day. By preventing bleeding into neighboring bronchi, which, in turn, avoids the risk of exacerbating hypoxia, bronchial occlusion with EWSs is highly effective in managing massive pulmonary hemorrhage during heart surgery.

Abstract
The bridging bronchus is a rare congenital airway anomaly in which the right upper lobe of the lung is supplied by the right main bronchus while the right lower lobe, and often the right middle lobe is supplied by an aberrant bronchus arising from the left main bronchus. The aberrant bronchus crosses (bridges) the lower part of the mediastinum, hence the term bridging bronchus (BB). This potentially life-threatening condition, usually accompanied by diffuse or focal airway stenosis, commonly presents with signs and symptoms related to large airway obstruction, such as respiratory distress, apnea, wheezing, stridor, and recurrent respiratory tract infections. Diagnosis of the BB is often challenging because the associated signs and symptoms mimic those of common conditions such as bacterial and viral bronchiolitis, bronchial asthma, cystic fibrosis, and foreign body aspiration. The BB is also often accompanied by congenital cardiovascular anomalies, including left pulmonary artery sling, atrial, and ventricular septal defects, tetralogy of Fallot, patent ductus arteriosus, and coarctation of the aorta. Patients presenting with the above signs and symptoms who are not responsive to standard treatment modalities, and have accompanying cardiovascular congenital anomalies should, therefore, be investigated for the BB. Herein, we review the anatomy, embryology, clinical presentation, differential diagnosis, imaging techniques and surgical management of the BB.

Abstract
BACKGROUND Airway invasion due to inoperable advanced esophageal cancers can sometimes cause serious complications includingairway stenosis and fistula, and compromise patients' QOL. We retrospectively evaluated the effect of tracheobronchial airway stentingfor airway stenosis due to inoperable advanced esophageal cancers. METHODS Between 2010 and 2017, 9 patients with airway stenosis due to inoperable advanced esophageal cancers were treated by placement of a tracheo- bronchial airway stent. RESULTS Eight patients were treated with self-expandable metallic stents and only 1 patient was treated with a Dumon Y stent. In all cases, tracheo-bronchial airway stents were successfully placed without major complications. Four patients received post-stentingtreatment and 5 patients could be discharged from the hospital. The median survival time after stent placement was 2.8 months. CONCLUSIONS Tracheo-bronchial airway stentingwas a safe and effective treatment for improvingpatients ' QOL.

Abstract
OBJECTIVE To evaluate the effect of end-tidal carbon dioxide (EtCO2) detection for location of the leading bronchus in patients with pneumothorax. METHODS Transbronchoscopic EtCO2 detection was performed in 4 patients with intractable pneumothorax in whom transbronchoscopic balloon detection failed to localize the leading bronchus. A specific bronchus was suspected to be the leading bronchus when its EtCO2 value was significantly lower than that of the main bronchus of the affected lung. After the pleural air leakage was successfully sealed by bronchial occlusion of the suspected bronchus, the EtCO2 was confirmed to indicate the leading bronchus. RESULTS Transbronchoscopic EtCO2 detection successfully located the leading bronchus in all 4 patients. CONCLUSIONS Transbronchoscopic EtCO2 detection is a new method of locating the leading bronchus in patients with intractable pneumothorax.

Abstract
OBJECTIVE To establish a new method for detecting the bronchus responsible for pulmonary air leakage by injecting methylene blue saline and to evaluate its efficacy and safety in cases with intractable pneumothorax and bronchial fistula. METHODS From January 2006 to October 2013, a total of 19 cases of intractable spontaneous pneumothorax and 8 cases of bronchial fistula were recruited in the study at the Fourth Hospital affiliated to Hebei Medical University. Of all the cases, 15 were diagnosed as having tension pneumothorax and 12 as having communicating pneumothorax. All the cases failed to respond to continuous pleural suction for more than 5 days and consented to the proposed treatment. Before procedure, chest suction was established to allow sustained airflow through the drainage tube while the patients breathed normally. Under direct vision through fiberoptic bronchoscope, injection catheter was inserted into the bronchoscopy channel, and methylene blue saline was slowly injected into the potentially leaking segmental or sub-segmental bronchi. When a steady decline or disappearance in the amount of methylene blue saline in the airways was observed, or methylthionine-tainted saline was detected within the chest drainage tube, the bronchus responsible for air leakage was indicated. Before blocking the target bronchus, the negative pressure level of pleural suction should be reduced or stopped, and then porcine fibrin glue or a-cyanoacrylate was used for sealing the bronchi associated with air leakage. When the air was absent from the drainage tube, and lung recruitment was indicated in the chest X-ray for 5 days, and bronchial blockade of air leakage was proved successful. RESULTS The bronchi responsible for air leakage were successfully located in all 27 cases, among them segmental bronchi were located in 16, subsegmental bronchi in 10, and small subsegmental bronchus in only one. Multiple adjacent segmental involvement occurred in 3, and multiple adjacent subsegmental involvement in 5 cases. The average time for locating the target bronchi was (51 ± 9) s, among them the average time for tension pneumothorax was (48 ± 15) s compared with (53 ± 16) s for communicating pneumothorax (t = 0.416, P = 0.699) . The average amount of methylene blue saline consumed for locating the target bronchi was (42 ± 23) ml. During the procedure, the membrane of the bronchi was kept intact, and the vital signs were stable. Blockade of the target bronchi was successful with fibrin glue in 20 cases and with OB glue in 7 cases. A total of 61 times of bronchial blocking were performed, and the airflow of the chest drainage tube was instantly stopped in 17 times, gradually stopped in 10, steadily reduced in 22 and no change in 12 times. Adverse effects included severe cough in 4 cases, fever in 3, pleural hemorrhage in 3, and chest pain, atelectasis, and pneumonia in 2 cases, respectively. CONCLUSION The bronchi responsible for pulmonary air leakage in patients with spontaneous pneumothorax and bronchial fistula could be determined by injecting methylene blue saline into the airways. This novel method does not require special instruments, and is easy to perform with a high safety and effectiveness.

Abstract
BACKGROUND Lower airway obstruction has evolved to denote pathologies associated with diseases of the lung, whereas, conditions proximal to the lung embody upper airway obstruction. This approach has disconnected diseases of the larynx and trachea from the lung, and removed the 'middle airway' from the interest and involvement of respiratory physicians and scientists. However, recent studies have indicated that dysfunction of this anatomical region may be a key component of overall airway obstruction, either independently or in combination with lung disease. New diagnostic modalities to effectively diagnose middle airway obstruction are being developed, and it has become feasible to identify and quantify middle airway obstruction. CONCLUSION We, therefore, propose adding 'middle airway obstruction' to our nomenclature to embed it in diagnostic approaches, and to allow due emphasis on this neglected anatomical region.

Abstract
OBJECTIVE it is more difficult and carries more risks to place airway stent under local anaesthesia for the patient with severe airway stenosis. The technique and method of domestically made recalled nitinol alloy stent implantation for severe airway stenosis was explored and evaluated. METHODS by using bronchoscopy via larynx mask, trachea intubation, or rigid bronchoscope under general anaesthesia and mechanical ventilation, stents are placed in the airway of patients with severe airway stenosis for which had been difficult to performed under local anaesthesia. RESULTS according to the various tracheobronchial lesions of patients, 42 stents were successfully placed in 40 patients, via larynx mask 23 cases, trachea intubation 11 cases, and rigid bronchoscope 6 cases under general anaesthesia and mechanical ventilation. No complications happened. The recalled nitinol alloy stents were placed in trachea 27 cases (membrane covered stent 9 cases), left primary bronchus 8 cases, right primary bronchus to medial segment 2 cases, trachea to left primary bronchus (wedge shaped stent) 5 cases respectively. The airway pressure decreased to normal level and other ventilator parameters also recovered after stents were placed. In most patients, the dyspnea index was improved immediately and the scores decreased from grades IV-V to grades 0-II, with higher scores indicating worse dyspnea. CONCLUSION for patients with severe airway stenosis, it is safer, effective and more comfortable to place the stent via larynx mask, trachea intubation, or rigid bronchoscope under general anaesthesia and mechanical ventilation compared to local anaesthesia and is worth spread and popularization in the future.

Abstract
Severe forms of pulmonary sarcoidosis are not frequent and include stage IV pulmonary involvement and specific complications of intrathoracic sarcoidosis. Pulmonary hypertension may be due to granulomatous involvement of vessels and/or extrinsic compression of pulmonary arteries by enlarged lymph nodes. Bronchial stenosis is rare and delay in therapy usually result in corticoresistance. Mycetomas may develop in cystic spaces and be responsible for severe haemoptysis. A better knowledge of these patterns is associated with a better management of severe sarcoidosis.

Abstract
OBJECTIVE To analyze the causes of benign central airway stenoses and to evaluate the efficacy of interventional treatments through flexible bronchoscopy. METHODS Three hundred and eighty-six outpatients and inpatients with benign central airway stenoses in our hospital from January 1999 to December 2006 were retrospectively analyzed. Interventional treatments through flexible bronchoscopy were used to treat the benign central airway stenoses. The endoscopic interventional treatments included laser, electrocautery, argon plasma coagulation, cryotherapy, balloon dilation and stent insertion. Airway diameters, FEV1 and dyspnea index of patients were evaluated before and immediately after the last treatment procedure. RESULTS The main causes of benign central airway stenoses were as follows: tuberculosis in 64.25% (248/386), secondary to prolonged orotracheal intubation or tracheotomy in 15.03% (58/386), injury in 3.63% (14/ 386) and inhalation burns in 3.11% (12/386), others were 54 cases. All the 386 patients received endoscopic interventional treatments. 89.89% (347/386) of the patients experienced improvement in dyspnea and cough. The average airway diameter increased from (2.49 +/- 1.57) mm to (6.41 +/- 1.70) mm (t = 47.427, P < 0.01). Dyspnea index decreased from 2.40 +/- 0.79 to 0.64 +/- 0.50 (t = 44.226, P < 0.01). The average value of FEV1 evaluated in 115 inpatients increased from (2.11 +/- 0.60) L to (3.46 +/- 0.75) L (t = 20.128, P < 0.01). Most patients needed multiple interventional treatments except 26 patients who received a single endoscopic treatment. Stable control of the diseases was achieved in 65.54% (253/ 386) patients 3 months after the last operation. CONCLUSION Tuberculosis is the most common cause of benign central airway stenoses in this series. Utilization of interventional methods through flexible bronchoscopy is effective in treating benign central airway stenoses.

Abstract
OBJECTIVES The aim of this study is to clarify the features of bronchial tuberculosis. MATERIALS AND METHODS We analyzed the clinicopathological data from 103 out of 4467 (2.3%) cases of culture positive tuberculosis admitted to the National Hospital Organization Tokyo National Hospital in the period from 1993 to 2004 in which bronchial tuberculosis was confirmed by bronchofiberscopy. RESULTS There were 62 women and 41 men, and 53 cases were less than 50 years old. The most common symptom, namely cough was observed in 70 cases, while 79 cases showed III1 to III2 on roentgenographic examination, and 81 cases were smear-positive for acid-fast bacilli in the sputum. Regarding the bronchofiberscopic findings, ulcers were detected in 60 cases, and the major site of bronchial tuberculosis was in the left main bronchus (35 cases). The number of the cases in which the time span from the onset of symptoms to diagnosis took over 3 months was 29, and 26 of them were "doctor's delay" cases which had a history of medical consultation resulting in diagnosis and treatment of other diseases, such as bronchial asthma (7 cases). There were 41 cases in which the second bronchofiberscopic findings have been reviewed, and regardless of the length of the span from the onset to diagnosis, the first bronchofiberscopy mostly revealed ulcer within 1 month after the start of treatment for tuberculosis, and 3 months after the start of treatment, many patients developed fibrous scars. Between 1999 to 2004, the first bronchofiberscopies were usually performed within 2 weeks to 1 month after the start of the treatment in contrast to the cases admitted between 1993 to 1998 in which bronchofribroscopy was mainly performed before the start of the treatment. However, there were no differences in the findings due to the timing of bronchofiberscopy. CONCLUSION The clinical characteristics of bronchial tuberculosis have not changed, and the delay of diagnosis of bronchial tuberculosis due to doctor's delay also continues to be an important issue today. In patients showing positive sputum smear for mycobacteria, the timing of bronchofiberscopy, although required upon medical examination, is considered to be more appropriately performed from 2 weeks to 1 month after the start of treatment from the view point of nosocomial tuberculosis infection control strategy.

Abstract
The incidence of occupational diseases is one of the basic indices of the effectiveness of prevention in the area of occupational health. It allows for the identification of jobs, plants and branches of the national economy with potentially increased risks for pathologies induced by working conditions. However, we should be aware of the fact that many of the recently diagnosed diseases result from long-term exposures experienced at work sites which are no longer under operation. The analysis was based on data included in occupational disease certificates. All sanitary and epidemiological stations throughout the country are committed to notify cases of occupational diseases to the National Register of Occupational Diseases at the Nofer Institute of Occupational Medicine in Łódź. After a significant increase in the number of occupational diseases (8305-12,017 cases per year) observed in 1980-1998, its decrease has been noted in Poland over the recent two years (9982 cases in 1999 and 7339 in 2000). In 1998-2000, a substantial decrease in the decreasing rate was also found (from 117.3 to 73.9 per 100,000 employed), which means that the decreasing trend does not result only from the increasing size of the working population in Poland. In 2000 like in previous years, among occupational diseases the following ones were most often diagnosed: diseases of vocal organ due to excessive voice effort most common in teachers, occupational hearing loss, pneumoconiosis, contagious and invasive diseases, dermatoses, chronic diseases of bronchi, vibration syndrome as well as acute and chronic poisonings. There were registered 6626 cases of the above listed diseases, that is 90.3% of all occupational diseases. In 1998-2000, a significant decrease in the incidence of this category of diseases was noted. The largest decrease applied to the vocal organ diseases, occupational hearing loss and contagious and invasive diseases (by 30%, 51% and 40%, respectively). Neither in the member states of the European Union, nor in the USA, vocal organ pathologies are listed among occupational diseases. The main reason for this is an inappropriate medical prevention in the group of teachers and somewhat limited opportunity to teach them how to use techniques of voice emission. A decreased incidence of occupational diseases observed in Poland in 1998-2000 results partly from improvements in working conditions and partly from more effective prevention.
