Effect of Dachengqi Decoction on NF-κB p65 Expression in Lung of Rats with Partial Intestinal Obstruction and the Underlying Mechanism

To investigate the effect of Dachengqi decoction on NF-κB p65 expression in lung of rats with partial intestinal obstruction and the underlying mechanism, 30 SD rats were randomly divided into three groups： sham-operation group, model group and Dachengqi decoction treatment group （Dachengqi group）, with 10 animals in each group. The models were made by partially ligating their large intestines outside the body. The pathological changes were analyzed by HE staining. The expression of NF-κB p65 in rats lung were measured by using real-time polymerase chain reaction and immunohistochemistry respectively. Moreover, the expression of caveolin-1 in rats lung was also measured to. Increased edema, interstitial thickening, hemorrhage, and infiltration of inflammatory cells were found in the model group. In contrast, this change was significantly reduced in Dachengqi group as compared with model group. In addition, the up-regulated caveolin-1 and NF-κB p65 were also suppressed by Dachengqi decoction in lung of rats with partial intestinal obstruction. We are led to concluded that the caveolin-l-NF-κB pathway plays an important role in the development of lung injury of rats with partial intestinal obstruction and Dachengqi decoction could down-regulate the expression of caveolin-1 and NF-κB p65 in lung of rats with partial intestinal obstruction.

Molecular mechanisms and cellular process in signal transduction pathway related to air pollutants in obstructive lung diseases:A mini-review

Exposure to air pollutants such as PM_(10),PM_(2.5),PM_(0.1),O_(3),CO,NO2,and SO_(2),and biological pollutants are important factors causing the evolution and furtherance of obstructive lung diseases(OLD),including asthma and chronic obstructive pulmonary disease(COPD).Asthma is the most frequent chronic inflammatory airway disease,characterized by breathlessness,wheezing,chest tightness,and cough,together with the presence of exaggerated expiratory airflow fluctuation that varies over time.COPD is a heterogeneous lung condition characterized by chronic respiratory symptoms such as dyspnea,cough,expectoration,and/or exacerbations due to abnormalities of the airways and/or alveoli that cause persistent,often progressive,airflow obstruction.Understanding the molecular mechanisms and cellular processes based on the development of OLD on exposure to air pollutants will provide insights into the solution of pathogenesis,prevention,and treatment of these conditions.The molecular mechanisms and cellular process involved in signal transduction pathway plays a role in the binding of extracellular signaling molecules and ligands to receptors placed on the cell surface or on the inner side cell that trigger inflammation that occurs,especially when something important enters the cell to bring into a cascade response.This binding then alters the cell metabolism,shape,and gene expression in the airway.This review aimed to reveal the effect of air pollutants on the molecular mechanisms and cellular processes involved in the signal transduction pathways in OLD.

Protective effect of sevoflurane on lung function of elderly chronic obstructive pulmonary disease patients undergoing total hip arthroplasty

BACKGROUND Chronic obstructive pulmonary disease(COPD)is a common respiratory disorder that affects the elderly population and increases the risk of postoperative pulmonary complications(PPCs)after major surgeries.Sevoflurane is a volatile anesthetic that has been shown to have anti-inflammatory and antioxidant properties and attenuate lung injury in animal models.AIM To evaluate the protective effect of sevoflurane on the lung function of elderly COPD patients undergoing total hip arthroplasty(THA).METHODS In this randomized controlled trial,we randomly assigned 120 elderly patients with COPD,who were scheduled for THA,to receive either sevoflurane(sevoflurane group)or propofol(propofol group)as the maintenance anesthetic.The primary outcome was the incidence of PPCs within seven days after surgery.The secondary outcomes were changes in the lung function parameters,inflammatory markers,oxidative stress markers,and postoperative pain scores.RESULTS The results showed that the incidence of PPCs was significantly lower in the sevoflurane group than in the propofol group(10%vs 25%,P=0.02).Furthermore,the decline in the forced expiratory volume in 1 s,forced vital capacity,and peak expiratory flow was significantly lesser in the sevoflurane group than in the propofol group at 24 h and 48 h after surgery(P<0.05).The interleukin-6,tumor necrosis factor-alpha,malondialdehyde,and 8-hydroxy-2α-deoxyguanosine levels were significantly lower in the sevoflurane group than in the propofol group at 24 h after surgery(P<0.05).The sevoflurane group showed significantly lower postoperative pain scores than the propofol group at 6 h,12 h,and 24 h after surgery(P<0.05).CONCLUSION Sevoflurane protects the lung function of elderly COPD patients undergoing THA under general anesthesia by reducing the incidence of PPCs,attenuating inflammatory and oxidative stress responses,and alleviating postoperative pain.

Effects of acetylcysteine on micro-inflammation and pulmonary ventilation in chronic obstructive pulmonary disease exacerbation

BACKGROUND Acute exacerbation of chronic obstructive pulmonary disease(AECOPD)is a serious complication of chronic obstructive pulmonary disease,often characterized by increased morbidity and mortality.In traditional Chinese medicine,AECOPD is linked to phlegm-heat and blood-stasis,presenting symptoms like thick sputum,fever,and chest pain.It has been shown that acetylcysteine inhalation in conjunction with conventional therapy significantly reduced inflammatory markers and improved lung function parameters in patients with AECOPD,suggesting that acetylcysteine may be an important adjunctive therapy for patients with phlegm-heat-blood stasis type AECOPD.AIM To investigate the effect of acetylcysteine on microinflammation and lung ventilation in patients with phlegm-heat and blood-stasis-type AECOPD.METHODS One hundred patients with phlegm-heat and blood-stasis-type AECOPD were randomly assigned to two groups.The treatment group received acetylcysteine inhalation(10%solution,5 mL,twice daily)along with conventional therapy,whereas the control group received only conventional therapy.The treatment duration was 14 d.Inflammatory markers(C-reactive protein,interleukin-6,and tumor necrosis factor-alpha)in the serum and sputum as well as lung function parameters(forced expiratory volume in one second,forced vital capacity,and peak expiratory flow)were assessed pre-and post-treatment.Acetylcysteine inhalation led to significant reductions in inflammatory markers and improvements in lung function parameters compared to those in the control group(P<0.05).This suggests that acetylcysteine could serve as an effective adjunct therapy for patients with phlegm-heat and blood-stasis-type AECOPD.RESULTS Acetylcysteine inhalation significantly reduced inflammatory markers in the serum and sputum and improved lung ventilation function parameters in patients with phlegm-heat and blood-stasis type AECOPD compared with the control group.These differences were statistically significant(P<0.05).The study concluded that acetylcysteine inhalation had a positive effect on microinflammation and lung ventilation function in patients with this type of AECOPD,suggesting its potential as an adjuvant therapy for such cases.CONCLUSION Acetylcysteine inhalation demonstrated significant improvements in reducing inflammatory markers in the serum and sputum,as well as enhancing lung ventilation function parameters in patients with phlegm-heat and bloodstasis type AECOPD.These findings suggest that acetylcysteine could serve as a valuable adjuvant therapy for individuals with this specific type of AECOPD,offering benefits for managing microinflammation and optimizing lung function.

Chronic obstructive pulmonary disease as a risk factor for lung cancer

The association between chronic obstructive pulmonary disease(COPD) and lung cancer has long been a subject of intense debate. The high prevalence of COPD in elderly smokers inevitably strengthens their coincidence. In addition to this contingent coincidence, recent studies have revealed a close association between the two diseases that is independent of the smoking history; that is, the existence of COPD is an independent risk factor for the development of lung cancer. Molecular-based evidence has been accumulating as a result of the efforts to explain the underlying mechanisms of this association. These mechanisms may include the following: the retention of airborne carcinogens followed by the activation of oncogenes and the suppression of tumor suppressor genes; the complex molecular mechanism associated with chronic inflammation in the distal airways of patients with COPD; the possible in-volvement of putative distal airway stem cells; and gel netic factors that are common to both COPD and lung cancer. The existence of COPD in patients with lung l cancer may potentially affect the process of diagnosis, surgical resection, radiotherapy, chemotherapy, and end-of-life care. The comprehensive management of COPD is extremely important for the appropriate treatment of lung cancer. Surgical resections with the aid of early interventions for COPD are often possible, even for patients with mild-to-moderate COPD. New challenges, such as lung cancer CT screening for individuals t at high risk, are now in the process of being implemented. Evaluating the risk of lung cancer in patients with COPD may be warranted in community-based lung cancer screening.

Role of chronic obstructive pulmonary disease in lung cancer pathogenesis

Chronic obstructive pulmonary disease(COPD) and lung cancer are two important smoking related conditions. However, COPD has been shown to be an independent risk factor for lung cancer regardless of smoking history, suggesting that COPD and lung cancer may share a common pathogenesis. This review summarizes the epidemiology of lung cancer and COPD briefly, as well as discussing the potential for shared genetic risk, and shared genomic mechanisms, such as epigenetic changes or DNA damage induced by smoking. How key areas of COPD pathogenesis, such as inflammation, oxidative stress and protease imbalance may contribute to subsequent development of cancer will also be covered. Finally the possibility that consequences of COPD, such as hypoxia, influence carcinogenesis will be reviewed. By understanding the pathogenesis of COPDand lung cancer in detail it is possible that new treatments may be developed and the risk of lung cancer in COPD may be reduced.

“肺主行水”理论在慢性阻塞性肺疾病气道黏液高分泌中的应用探讨

慢性阻塞性肺疾病是一种以持续性气流受限为主要特征的慢性气道炎症性疾病。气道黏液高分泌是慢性阻塞性肺疾病重要临床特征,主要是由于气道受到长期炎症刺激,杯状细胞产生过多,导致黏液堆积,产生咳嗽、咳痰等临床表现。气道黏液高分泌的实质是津液的代谢失常,而“肺主行水”是指肺气通过宣发和肃降推动和调节全身的津液代谢。慢性阻塞性肺疾病是肺失宣降的病理表现,气道黏液高分泌则是“肺主行水”功能异常的体现。在治疗上,西医以减少黏液分泌、抑制炎症等为主;中医以调理肺气宣降、调节水液代谢为基本治疗原则。“肺主行水”理论为慢性阻塞性肺疾病气道黏液高分泌的研究提供了新思路。
