Chronic obstructive pulmonary disease (COPD), characterized by persistent and not fully reversible airflow restrictions, is currently one of the most widespread chronic lung diseases in the world. The most common symptoms of COPD are cough, expectoration, and exertional dyspnea. Although various strategies have been developed during the last few decades, current medical treatment for COPD only focuses on the relief of symptoms, and the reversal of lung function deterioration and improvement in patient's quality of life are very limited. Consequently, development of novel effective therapeutic strategies for COPD is urgently needed. Stem cells were known to differentiate into a variety of cell types and used to regenerate lung parenchyma and airway structures. Stem cell therapy is a promising therapeutic strategy that has the potential to restore the lung function and improve the quality of life in patients with COPD. This review summarizes the current state of knowledge regarding the clinical research on the treatment of COPD with mesenchymal stem cells (MSCs) and aims to update the understanding of the role of MSCs in COPD treatment, which may be helpful for developing effective therapeutic strategies in clinical settings.

Bronchial asthma (i.e. asthma) is a chronic inflammatory disease characterized by airway inflammatory response, hyperresponsiveness and airway remodeling, in which T cells play a vital role, especially T helper cells (Th cells). Non-coding RNAs (ncRNAs) are the RNAs that do not encode proteins, mainly including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), which are widely found in eukaryotic genomes and participate in the regulation of various biological processes. Previous studies have shown that ncRNAs play an important role in the activation and transformation of T cells and other biological processes in asthma. The specific molecular mechanism and clinical application are worth in-depth discussion. This article reviewed the research progress in regulation of miRNAs, lncRNAs and circRNAs on T cells in asthma in recent years.

The number of smokers in Chinese rural areas is more than 200 million, which is twice that in cities. It is very significant to carry out tobacco control interventions in rural areas. We performed this community intervention study to evaluate the efficacy of village-based health education of tobacco control on the male current smoking rate in rural areas. The population of this study was the males above 15 years old from 6 villages in rural areas. The villages were randomly assigned to intervention group or control group (3 villages in each group). Self-designed smoking questionnaire was applied. The intervention group received the village-based health education of tobacco control for one year. The primary outcome measurement was the male current smoking rate. In the baseline investigation, completed surveys were returned by 814 male residents from the control group and 831 male residents from the intervention group. The male current smoking rate in the control group and the intervention group was 61.2% and 58.5%, respectively, before intervention. There was no significant difference between these two groups (P>0.05). After one-year intervention, the current smoking rate in the intervention group (51.2%) was significantly lower than that in the control group (62.8%) (P<0.001). Our study suggested that the village-based health education of tobacco control was effective in lowering the male current smoking rate in rural areas, which could be a suitable and feasible way for tobacco control in the Chinese rural areas.

Many studies have reported the relationship between CXCL12 G801A polymorphism and cancer risk, with conflicting results. In this study, we tried to clarify the possibility that this polymorphism may increase cancer risk by conducting an updated meta-analysis. PubMed and EMbase were searched for case-control studies regarding the association of the gene polymorphism and cancer risk. Data were extracted and odds ratios (ORs) with 95% confidence intervals (95% CIs) were used to assess the strength of the association. Heterogeneity among articles and publication bias was also assessed. Significantly increased risk for cancer was found (A vs. G: OR=1.26, 95% CI=1.13-1.40, P<0.01; AA+AG vs. GG: OR=1.33, 95% CI=1.16-1.52, P<0.01). In subgroup analysis, statistically elevated cancer risk was found in both Asian and Caucasian populations (for Asian, AA+AG vs. GG: OR=1.74, 95% CI=1.22-2.47, P<0.01; for Caucasian, AA+AG vs. GG: OR=1.24, 95% CI=1.09-1.42, P<0.01). Our result indicated that CXCL12 G801A polymorphism is a risk factor for cancer. To validate the finding, further large-size case-control studies are warranted.

Alveolar epithelial type II (AT II) cells are essential for lung development and remodeling, as they are precursors for type I cells and also produce other non-repair cells (fibroblasts). Progenitor cells are believed to possess capability of multi-potent transdifferentiation, which is closely related to the niche, suggesting the importance of establishment of a lung progenitor cell niche model. We hypothesized that pulmonary surfactant-associated protein A (SPA) suicide gene system would cause AT II cell to kill itself through apoptosis and leave its niche. In vitro, the recombinant adeno-associated virus vectors-SPA-thymidine kinase (rAAV-SPA-TK) system was established to get targeted apoptotic AT II cells. The apoptosis of AT II cells was detected by using MTT. The results showed that cloned SPA gene promoter had specific transcriptional activity in SPA high expression cells, and SPA high expression cells (H441) transfected with TK gene had higher sensitivity to ganciclovir (GCV) than SPA low expression cells (A549). In vivo, increased apoptosis of AT II cells induced by GCV in rAAV-SPA-TK system was observed by TUNEL. Finally, the successful packaging and application of rAAV-SPA-TK system provide experimental basis to get specific lung progenitor cell (AT II) niche in vitro and in vivo.

Numerous studies have been done to explore the association between mannose-binding lectin two (MBL2) gene polymorphisms and the risk of tuberculosis (TB). However, the results are inconsistent. We performed a meta-analysis to investigate whether polymorphisms in the MBL2 gene were associated with TB risk. Databases including PubMed, Medline, Chinese Biomedicine Database, China National Knowledge Infrastructure, Wanfang Database, and Weipu Database were searched to find relevant articles published up to 2 October, 2012. Odds ratio (OR) with 95% confidence interval (CI) was used to evaluate the strength of association. All statistical tests were performed by using Revman 5.1 software and STATA 11.0 software. Six case-control studies including 1106 cases and 1190 controls were accepted in the meta-analysis. The results indicated that individuals carrying the MBL2 codon 54 B allele may have an increased risk of TB as compared with AA homozygotes (BB+AB vs. AA: OR=1.52, 95% CI: 1.22-1.88), whereas MBL2 +4 P/Q was possibly not associated with TB susceptibility in Chinese population.

This study examined the expression of the anterior gradient-2 (AGR2) protein and Muc5ac protein in the lung tissues of asthmatic mice and the effect of dexamethasone, with an attempt to explore the role of AGR2 in the over-secretion of mucus in the airway. Eighteen BALB/c mice were divided into asthma group, control group and dexamethasone group. In dexamethasone group, dexamethasone was intraperitoneally administered. Expression of AGR2 protein and Muc5ac protein in the murine lung tissues was immunohistochemically detected. IL-13 level was determined in the bronchoalveolar lavage fluid (BALF) by ELISA. The results exhibited that the expression of AGR2 protein in asthma group (0.522±0.041) was significantly higher than that in normal controls (0.361±0.047) (P<0.01) and bore a positive linear relationship to the expression of Muc5ac protein (r=0.873, P<0.05) and IL-13 level (r=0.828, P<0.05). Expression of AGR2 protein in the dexamethasone group (0.456±0.049) was significantly lower than that in the asthma group. It was concluded that: (1) the expression of AGR2 protein was significantly higher in asthmatic mice as compared with their normal counterparts; (2) the expression was obviously related to the expression of Muc5ac protein and IL-13; (3) dexamethasone could down-regulate the expression of AGR2 protein. Our findings suggested that AGR2 might be involved in the over-secretion of mucus in the airway in asthma.

In order to study whether cysteine-rich 61 protein (cyr61) is involved in the pathogenesis of asthma and its relation to airway inflammation, the effect of dexamethasone (Dxm) on the expression of cyr61 in the lung tissues of asthmatic mice was investigated. Forty BALB/c mice were divided into asthma group (n=15), control group (n=10) and Dxm group (n=15). The asthma group was sensitized and challenged by ovalbumin (OVA). The mice in Dxm group were intraperitoneally administered with Dxm after OVA challenge. The expression of cyr61 in the lung tissues was detected by using immunohistochemistry, and that of eotaxin protein in the bronchoalveolar lavage fluid (BALF) by using enzyme-linked immunosorbent assay (ELISA). The number of inflammatory cells in BALF was also analyzed. The results showed that the cyr61 expression was highest in asthma group (P<0.05), followed by Dxm group (P<0.05) and control group. The cyr61 had a positive correlation with the total nucleated cells (r=0.867, P<0.05), especially eosinophils (r=0.856, P<0.05), and eotaxin level (r=0.983, P<0.05) in the BALF. Our findings suggested that cyr61 is expressed in airway epithelial cells and has a positive correlation with eotaxin and number of airway infiltrating eosinophils.

<p><b>BACKGROUND</b>The extracellular signal-regulated kinase (ERK) is widely expressed in mammal cells and involved in airway proliferation and remodeling in asthma. In this study, we intend to explore the role of ERK in the expression of the Th2 cytokine, interleukin 13 (IL-13) in lymphocytes in asthma.</p><p><b>METHODS</b>Forty Sprague-Dawley rats were randomly divided into two groups: normal control and asthmatic groups. Peripheral blood lymphocytes were isolated and purified from the blood of each rat and divided into five groups: control, asthmatic lymphocytes, asthmatic cells stimulated with ERK activator epidermal growth factor (EGF), or with ERK inhibitor PD98059, or with EGF and PD98059 together. The expression of phosphorylated-ERK (p-ERK) was observed by immunocytochemical staining, the expression of ERK mRNA was determined by reverse transcriptase-PCR, IL-13 protein in supernatants was measured by ELISA.</p><p><b>RESULTS</b>(1) The ERK mRNA level and the percentage of cells with p-ERK in lymphocytes from asthmatic rats were significantly higher than those in normal controls, and were significantly increased by EGF administration. This effect of EGF was significantly inhibited by PD98059 pretreatment. (2) IL-13 protein in supernatants of asthmatic lymphocytes was higher than that produced by normal control lymphocytes, and was significantly increased by EGF treatment. This EGF effect was partly blocked by PD98059 pretreatment. (3) There was a significant positive correlation between the percentage of cells with p-ERK in peripheral blood lymphocytes and IL-13 protein in supernatants of lymphocytes from asthmatic rats.</p><p><b>CONCLUSIONS</b>In asthma the ERK expression and activation levels were increased, as was the protein level of IL-13. The ERK signaling pathway may be involved in the increased expression of the Th2 cytokine IL-13 in asthma.</p>
