Chronic obstructive pulmonary disease (COPD) is a major public health problem worldwide. Pulmonary rehabilitation (PR) is an established intervention for the management of patients with COPD. Exercise training is an important part of PR, and its effectiveness in patients with COPD is well established. However, alternative methods of PR training such as Daoyin have not been appropriately studied. Hence, alternative forms of exercise training that require less exercise equipment and no specific training place should be evaluated. This paper describes the study protocol of a clinical trial that aims to determine if pulmonary Daoyin training will improve the exercise capacity and psychosocial function of patients with COPD in China.

Objective:To investigate the effects and related mechanism of estrogen receptor β (ERβ) agonist on the migration and oxidative stress of human umbilial vein endothelial cells (HUVECs) under high glucose condition.Methods:The experimental research method was adopted. HUVECs were routinely cultured and passaged, and then cells of the logarithmic growth phase were collected for the subsequent experiments. The cells were divided into three groups according to the random number table, including normal control group (cultured with Roswell Park Memorial Institute 1640 cell culture medium (the same cell culture medium below) containing 5.5 mmol/L D-glucose), high glucose alone group (cultured with cell culture medium containing 25.0 mmol/L D-glucose alone), and high glucose+ERβ agonist diarylpropionitrile (DPN) group (cultured with cell culture medium containing 25.0 mmol/L D-glucose and 10 μmol/L DPN). Scratch test was conducted to detect the cell migration rate in the 3 groups at 24 h post scratching. Fluorescent probe method was used to detect the reactive oxygen species (ROS, denoted by red fluorescence intensity) of cells in the 3 groups on 5 d post culture. Western blotting was used to detect the protein expression levels of vascular endothelial growth factor (VEGF) and superoxide dismutase 2 (SOD2) of cells in the 3 groups on 5 d post culture. In the above-mentioned experiments, cells were grouped and cultured correspondingly as before, the number of samples in each group was 5. Data were statistically analyzed with one-way analysis of variance and least significant difference t test. Results:At 24 h post scratching, the cell migration rate in high glucose alone group was (36±5)%, which was significantly lower than (76±4)% of normal control group and (65±5)% of high glucose+DPN group ( t=14.511, 9.603, P<0.01), and the cell migration rate in high glucose+DPN group was significantly lower than that in normal control group ( t=3.943, P<0.01). On 5 d post culture, the level of ROS of cells in high glucose alone group (1.81±0.12) was significantly increased compared with normal control group and high glucose+DPN group (1.00±0.14, 0.91±0.15, t=9.679, 10.549, P<0.01), while the level of ROS of cells in normal control group and high glucose+DPN group were close ( t=1.031, P>0.05). On 5 d post culture, the protein expression levels of VEGF and SOD2 of cells in high glucose alone group were significantly lower than the levels of normal control group ( t=14.175, 13.787, P<0.01) and high glucose+DPN group ( t=6.321, 17.750, P<0.01). The protein expression level of VEGF of cells in high glucose+DPN group was significantly lower than the level of normal control group ( t=7.206, P<0.05), while the protein expression level of SOD2 of cells in high glucose+DPN group was significantly higher than the level of normal control group ( t=2.890, P<0.05). Conclusions:The activation of ERβ can improve the inhibition of HUVECs migration induced by high glucose and alleviate oxidative stress injury induced by high glucose, which may be achieved by promoting the expression of VEGF and SOD2.

Objective:To observe the changes in the related indicators of bone formation and bone resorption in severely burned rats.Methods:The experimental research method was adopted. Thirty female Sprague-Dawley rats aged 6 to 8 weeks were divided into sham injury group, 12% total body surface area (TBSA) full-thickness burn group, and 24%TBSA full-thickness burn group according to the random number table, with 10 rats in each group. The rats were treated on the back correspondingly, after which, the burned rats were rehydrated by intraperitoneal injection according to the Parkland formula, and the wound was coated with 20 g/L iodophor until wound healing. On post injury day (PID) 28, the tibia tissue of rats in each group was collected. The new bone tissue and the number of osteoclasts were observed after staining with Masson and tartrate-resistant acid phosphatase, respectively. The abdominal aortic blood of rats in each group was harvested for serum preparation. The bone metabolism indexes of serum calcium ion and phosphorus ion concentration were determined by the methyl thymol blue colorimetric method and phosphomolybdic acid method, respectively. The serum levels of bone formation marker of aminoterminal propeptide of type 1 procollagen (P1NP) and bone resorption marker of beta-carboxy-terminated peptide of type Ⅰ collagen (β-CTX) were determined by enzyme-linked immunosorbent assay. The first lumbar spine tissue of rats in each group was collected, and the mRNA expression levels of osteoprotegerin, receptor activator of nuclear factor-κB ligand (RANKL), tumor necrosis factor receptor-associated factor 6 (TRAF-6), nuclear factor of activated T cell 1 (NFATC1), c-Fos, and c-Src were detected by real-time fluorescent quantitative reverse transcription polymerase chain reaction. Data were statistically analyzed with one-way analysis of variance, Bonferroni method, Welch test, Games-Howell test, Kruskal-Wallis test, Mann-Whitney U test, and Bonferroni correction. Results:On PID 28, compared with that in sham injury group, the formation of new bone tissue in the tibia tissue of rats in the two burn groups was decreased, and the larger the burn area, the more obvious the decrease. The numbers of osteoclasts in the tibia tissue of rats in the two burn groups were similar, both significantly more than the number in sham injury group. On PID 28, the serum calcium ion concentration and serum level of β-CTX of rats in the three groups were similar ( P>0.05). The serum phosphorus ion concentration of rats in 24%TBSA full-thickness burn group was significantly higher than that in 12%TBSA full-thickness burn group ( P<0.05), and the serum phosphorus ion concentrations in the two burn groups were significantly higher than the concentration in sham injury group ( P<0.01). The serum level of P1NP of rats in 24%TBSA full-thickness burn group was significantly lower than that in sham injury group ( P<0.01). On PID 28, the mRNA expression levels of osteoprotegerin in the first lumbar spine tissue of rats in sham injury group, 12%TBSA full-thickness burn group, and 24%TBSA full-thickness burn group were 1.01±0.20, 1.71±0.83, and 2.24±0.51, respectively, and that in 24%TBSA full-thickness burn group was significantly higher than that in sham injury group ( P<0.01). The mRNA expression level of RANKL in the first lumbar spine tissue of rats in 24%TBSA full-thickness burn group was 1.31±0.17, which was significantly higher than 1.00±0.14 in sham injury group and 0.97±0.10 in 12%TBSA full-thickness burn group ( P<0.01). The mRNA expression levels of TRAF-6, NFATC1 ( Z=3.141, 3.782), and c-Src in the first lumbar tissue of rats in 12%TBSA full-thickness burn group and 24%TBSA full-thickness burn group and the mRNA expression level of c-Fos in the first lumbar tissue of rats in 12%TBSA full-thickness burn group were significantly higher than those in sham injury group ( P<0.05 or P<0.01). The mRNA expression levels of c-Fos and c-Src in the first lumbar spine tissue of rats in 12%TBSA full-thickness burn group were significantly higher than those in 24%TBSA full-thickness burn group ( P<0.01). Conclusions:Severe burns can cause a decrease in the generation of new bone tissue, an increase in the number of osteoclasts and the serum phosphorus ion concentration, and a decrease in the serum level of P1NP in rats. The level of osteoprotegerin, RANKL, TRAF-6, NFATC1, c-Fos, and c-Src in bone tissue showed an increasing trend while the level of NFATC1, c-Fos, and c-Src showed a decreasing trend with the increase of burn area.

The low expression rate of exogenous genes in cyanobacteria is one of the bottlenecks of cyanobacteria genetic engineering. The T7 RNA polymerase expression system has achieved the efficient expression of exogenous genes in Escherichia coli. Cyanobacteria and E. coli are both Gram-negative bacteria with high genetic homology. The construction of T7 RNA polymerase expression system in cyanobacteria may improve the expression of foreign genes. In order to construct the T7 RNA polymerase expression system in Anabaena sp. PCC 7120, methods such as overlapping extension PCR and digestion-ligation technique were used to construct a site-specific integration vector pEASY-T1-F1-TacT7RNAPCmR-F2 and a shuttle expression vector pRL-T7-hG-CSF. The site-specific integration vector is capable of expressing T7 RNA polymerase, and the shuttle expression vector expresses hG-CSF driven by the T7 promoter. Then we introduced the site-specific integration vector into the wild type cyanobacteria by electroporation and transferred the shuttle expression vector into the site-integrated transgenic cyanobacteria by triparental conjugative transfer. In the end, we identified the presence of foreign genes in cyanobacteria by PCR, tested the transcription level of foreign genes in cyanobacteria by RT-PCR, and detected the protein expression of foreign genes in cyanobacteria by Western blotting. The two vectors were successfully constructed, the T7 RNA polymerase gene and hG-CSF gene were transferred into cyanobacteria well, and both genes were also expressed in cyanobacteria. In summary, the T7 RNA polymerase expression system was successfully constructed in cyanobacteria, and the expression rate of hG-CSF gene was doubled than the traditional cyanobacteria expression systems. This expression system will provide a better tool for the application of cyanobacteria genetic engineering and will promote the development of cyanobacteria as a chassis cell in the fields of synthetic biology in the future.
