Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality throughout the world and is mainly characterized by persistent airflow limitation. Given that multiple systems other than the lung can be impaired in COPD patients, the traditional FEV1/FVC ratio shows many limitations in COPD diagnosis and assessment. Certain heterogeneities are found in terms of clinical manifestations, physiology, imaging findings, and inflammatory reactions in COPD patients; thus, phenotyping can provide effective information for the prognosis and treatment. However, phenotypes are often based on symptoms or pathophysiological impairments in late-stage COPD, and the role of phenotypes in COPD prevention and early diagnosis remains unclear. This shortcoming may be overcome by the potential genotypes defined by the heterogeneities in certain genes. This review briefly describes the heterogeneity of COPD, with focus on recent advances in the correlations between genotypes and phenotypes. The potential roles of these genotypes and phenotypes in the molecular mechanisms and management of COPD are also elucidated.

Peritoneal dialysis (PD) is an established form of renal replacement therapy. Long-term PD leads to morphologic and functional changes to the peritoneal membrane (PM), which is defined as peritoneal fibrosis, a known cause of loss of peritoneal ultrafiltration capacity. Inflammation and angiogenesis are key events during the pathogenesis of peritoneal fibrosis. This review discusses the pathophysiology of peritoneal fibrosis and recent research progress on key fibrogenic molecular mechanisms in peritoneal inflammation and angiogenesis, including Toll-like receptor ligand-mediated, NOD-like receptor protein 3/interleukin-1β, vascular endothelial growth factor, and angiopoietin-2/Tie2 signaling pathways. Furthermore, novel strategies targeting peritoneal inflammation and angiogenesis to preserve the PM are discussed in depth.

Recent evidences suggested that cyclic guanosine monophosphate-specific phosphodiesterase 5 (PDE5) inhibitor represents an important therapeutic target for cardiovascular diseases. Whether and how it ameliorates cardiac fibrosis, a major cause of diastolic dysfunction and heart failure, is unknown. The purpose of this study was to investigate the effects of PDE5 inhibitor on cardiac fibrosis. We assessed cardiac fibrosis and pathology in mice subjected to transverse aortic constriction (TAC). Oral sildenafil, a PDE5 inhibitor, was administered in the therapy group. In control mice, 4 weeks of TAC induced significant cardiac dysfunction, cardiac fibrosis, and cardiac fibroblast activation (proliferation and transformation to myofibroblasts). Sildenafil treatment markedly prevented TAC-induced cardiac dysfunction, cardiac fibrosis and cardiac fibroblast activation but did not block TAC-induced transforming growth factor-β1 (TGF-β1) production and phosphorylation of Smad2/3. In isolated cardiac fibroblasts, sildenafil blocked TGF-β1-induced cardiac fibroblast transformation, proliferation and collagen synthesis. Furthermore, we found that sildenafil induced phosphorylated cAMP response element binding protein (CREB) and reduced CREB-binding protein 1 (CBP1) recruitment to Smad transcriptional complexes. PDE5 inhibition prevents cardiac fibrosis by reducing CBP1 recruitment to Smad transcriptional complexes through CREB activation in cardiac fibroblasts.

Due to the implementation of directly observed treatment strategy (DOTS), China has made a significant achievement in tackling the tuberculosis (TB) epidemic in the 1990s. However, only half of regions in China met or exceeded the 85% rate of treatment success target. The aim of the present study is to summarize the treatment outcomes of smear-positive pulmonary TB in the mainland of China in the past decade using meta-analysis based on systematic review of published observational studies. A total of 50 eligible articles (58 studies) were identified and included in this study. The summarized treatment success rates were 93.9% (95% CI, 92.8%–94.7%) for new cases and 85.4% (95% CI, 83.0%–87.6%) for previously treated cases, and the summarized cured rate were 92.2% (95% CI, 90.9%–93.3%) and 81.2% (95% CI, 79.1%–83.1%), respectively. A remarkable increase of rates for treatment success and cure was observed in the 1990s. After 2000, the summarized treatment outcomes were tending towards stability. In addition, geographic areas, type of the data and administrative level of the hospital were also found to influence the estimates of the treatment outcomes. Results of the present study clearly show, in general, that the pulmonary TB treatment achieved significant success in the past decade in the mainland of China. However, it needs to be further strengthened in the central and west areas.

Pulmonary hypertension (PH), as a complication of bronchiectasis, is associated with increased mortality. However, hemodynamic characteristics and the efficacy of pulmonary arterial hypertension (PAH) therapies in patients with bronchiectasis and PH remain unknown. Patients with bilateral bronchiectasis and concurrent PH were included in the study. Patient characteristics at baseline and during follow-up, as well as survival, were analyzed. This observational study was conducted in 36 patients with a mean age of 51.5 years (range, 17?74 years). The 6 min walking distance was 300.8±93.3 m. The mean pulmonary arterial pressure (PAP) was 41.5±11.7 mmHg, cardiac output was 5.2±1.4 L/min, and pulmonary vascular resistance was 561.5±281.5 dyn·s·cm−5. The mean PAP was>35 mmHg in 75% of the cases. Mean PAP was inversely correlated with arterial oxygen saturation values (r = −0.45, P = 0.02). In 24 patients who received oral PAH therapy, systolic PAP was reduced from 82.4±27.0 mmHg to 65.5±20.9 mmHg (P = 0.025) on echocardiography after a median of 6 months of follow-up. The overall probability of survival was 97.1% at 1 year, 83.4% at 3 years, and 64.5% at 5 years. Given the results, we conclude that PH with severe hemodynamic impairment can occur in patients with bilateral bronchiectasis, and PAH therapy might improve hemodynamics in such patients. Prospective clinical trials focusing on this patient population are warranted.

Cystic fibrosis (CF) is a fatal autosomal-recessive disease caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. CF is characterized by recurrent pulmonary infection with obstructive pulmonary disease. CF is common in the Caucasian population but is rare in the Chinese population. The symptoms of early-stage CF are often untypical and may sometimes manifest as Bartter syndrome (BS)-like hypokalemic alkalosis. Therefore, the ability of doctors to differentiate CF from BS-like hypokalemic alkalosis in Chinese infants is a great challenge in the timely and accurate diagnosis of CF. In China, sporadic CF has not been diagnosed in children younger than three years of age to date. Three infants, who were initially admitted to our hospital over the period of June 2013 to September 2014 with BS-like hypokalemic alkalosis, were diagnosed with CF through exome sequencing and sweat chloride measurement. The compound heterozygous mutations of the CFTR gene were detected in two infants, and a homozygous missense mutation was found in one infant. Among the six identified mutations, two are novel point mutations (c.1526G>C and c.3062C>T) that are possibly pathogenic. The three infants are the youngest Chinese patients to have been diagnosed with sporadic CF at a very early stage. Follow-up examination showed that all of the cases remained symptom-free after early intervention, indicating the potential benefit of very early diagnosis and timely intervention in children with CF. Our results demonstrate the necessity of distinguishing CF from BS in Chinese infants with hypokalemic alkalosis and the significant diagnostic value of powerful exome sequencing for rare genetic diseases. Furthermore, our findings expand the CFTR mutation spectrum associated with CF.
