Objective To observe the efficacy of early pulmonary rehabilitation training on respiratory function of patients with hypox-emia after coronary artery bypass grafting. Methods From February, 2013 to September, 2016, 53 patients with hypoxemia after coronary ar-tery bypass grafting were randomly divided into control group (n=25) and observation group (n=28). Both of them received routine therapy, while the observation group received pulmonary rehabilitation training in addition. Results Three days after extubation, the forced expirato-ry volume in one second (FEV1) (measured) and FEV1/forced vital capacity (FVC) were higher in the observation group than in the control group (t>3.590, P<0.01), while the level of PaO2 was higher (t=5.824, P<0.001); the FEV1 (measured), FEV1(measured/ predicted) and FEV1/FVC decreased in both groups (F>1.044, P<0.05). The hospital stay was shorter (t=―2.138, P=0.037). The level of PaO2 was the high-est one day after extubation among three time points in both groups (P<0.001). No significantly difference was observed in mechanical ven-tilation time and ICU stay between two groups (P>0.05). Conclusion Early respiratory exerciser training could improve the respiratory func-tion of patients with hypoxemia after coronary artery bypass grafting, shorten hospital stay.

Objective To investigate the epidemiological characteristics of non-toxic goiter and non-toxic thyroid nodules in the regions with different iodine intakes and the factors influencing the occurrence, development and outcome of goiter and thyroid nodules. Methods 3 385 subjects, who had taken part in the previous survey in 1999 with the ultrasonic examination of thyroid, were composed of individuals in Panshan with chronic mild iodine deficiency,in Zhangwu with more than adequate iodine "after iodine supplementation and in Huanghua with excessive iodine. These 3 groups of subjects were followed up in 2004. Results (1) The cumulative incidences of diffuse goiter in Panshan ,Zhangwu and Huanghua were 7.1% ,4.4% and 6.9% ,respectively ,being the lowest in Zhangwu (P<0.01) and those of nodular goiter were 5.0% ,2. 4% and 0.8%, respectively, being the highest in Panshan (P<0.01). (2) The incidences of single nodule were 4.0% ,5.7% and 5.6%, respectively, and those of multiple nodules 0.4%, 1.2% and 1.0%, respectively. (3)The result of logistic analysis showed that iodine deficiency,iodine excess and positive thyroid autoantibodies (TAA) were the independent risk factors for the occurrence of goiter. (4)In Zhangwu ,the incidence of non-toxic goiter in the group with positive TAA was higher than that in the group with negative TAA(P<0.01) ,while there were no such differences in Panshan and Huanghua. (5)In these three regions, the rates of positive TAA in the individuals with diffuse non-toxic goiter were higher than those in the healthy subjects (P<0.05). And in Huanghua,the rate of positive TAA in subjects with non-toxic nodular goiter was also higher than that in the healthy individuals (P<0.05). Conclusion Iodine deficiency and iodine excess may both induce the raising incidence of goiter. Nodular goiter is prevalent in iodine deficient district and diffuse goiter is the predominant form in places with iodine excess. Thyroid autoimmunity is associated with occurrence and maintenance of goiter, and this phenomenon is more obvious in the community with previous iodine deficiency followed then by treatment with more than adequate iodine.

The aim of this study was to clone the goat RPL29 gene and analyze its effect on lipogenesis in intramuscular adipocytes. Using Jianzhou big-eared goats as the object, the goat RPL29 gene was cloned by reverse transcription-polymerase chain reaction (RT-PCR), the gene structure and expressed protein sequence were analyzed by bioinformatics, and the mRNA expression levels of RPL29 in various tissues and different differentiation stages of intramuscular adipocytes of goats were detected by quantitative real-time PCR (qRT-PCR). The RPL29 overexpression vector pEGFP-N1-RPL29 constructed by gene recombination was used to transfect into goat intramuscular preadipocytes and induce differentiation. Subsequently, the effect of overexpression of RPL29 on fat droplet accumulation was revealed morphologically by oil red O and Bodipy staining, and changes in the expression levels of genes related to lipid metabolism were detected by qRT-PCR. The results showed that the length of the goat RPL29 was 507 bp, including a coding sequence (CDS) region of 471 bp which encodes 156 amino acid residues. It is a positively charged and stable hydrophilic protein mainly distributed in the nucleus of cells. Tissue expression profiling showed that the expression level of this gene was much higher in subcutaneous adipose tissue and inter-abdominal adipose tissue of goats than in other tissues (P < 0.05). The temporal expression profile showed that the gene was expressed at the highest level at 84 h of differentiation in goat intramuscular adipocytes, which was highly significantly higher than that in the undifferentiated period (P < 0.01). Overexpression of RPL29 promoted lipid accumulation in intramuscular adipocytes, and the optical density values of oil red O staining were significantly increased (P < 0.05). In addition, overexpression of RPL29 was followed by a highly significant increase in ATGL and ACC gene expression (P < 0.01) and a significant increase in FASN gene expression (P < 0.05). In conclusion, the goat RPL29 may promote intra-muscular adipocyte deposition in goats by up-regulating FASN, ACC and ATGL.

The aim of this study was to investigate the effect of activating transcription factor 3 (ATF3) on the differentiation of intramuscular preadipocytes in goat, and to elucidate its possible action pathway at the molecular level. In this study, the recombinant plasmid of goat pEGFP-N1-ATF3 was constructed, and the intramuscular preadipocytes were transfected with liposomes. The relative expression levels of adipocyte differentiation marker genes were detected by quantitative real-time PCR (qRT-PCR). After transfection of goat intramuscular preadipocytes with the goat pEGFP-N1-ATF3 overexpression vector, it was found that the accumulation of lipid droplets was inhibited, and the adipocyte differentiation markers PPARγ, C/EBPα and SREBP1 were extremely significantly down-regulated (P < 0.01), while C/EBPβ and AP2 were significantly down-regulated (P < 0.05). The ATF3 binding sites were predicted to exist in the promoter regions of PPARγ, C/EBPα and AP2 by the ALGGEN PROMO program. The overexpression of goat ATF3 inhibits the accumulation of lipid droplets in intramuscular preadipocytes, and this effect may be achieved by down-regulating PPARγ, C/EBPα and AP2. These results may facilitate elucidation of the regulatory mechanism of ATF3 in regulating the differentiation of goat intramuscular preadipocytes.

This study aimed to explore the effect of miR-23b-3p on the differentiation of goat intramuscular preadipocytes, and to confirm whether miR-23b-3p plays its roles via targeting the PDE4B gene. Based on the pre-transcriptome sequencing data obtained previously, the miR-23b-3p, which was differentially expressed in goat intramuscular adipocytes before and after differentiation, was used as an entry point. real-time quantitative-polymerase chain reaction (qPCR) was used to detect the expression pattern of miR-23b-3p during the differentiation of goat intramuscular preadipocytes. The effects of miR-23b-3p on adipose differentiation and adipose differentiation marker genes were determined at the morphological and molecular levels. The downstream target genes of miR-23b-3p were determined using bioinformatics prediction as well as dual luciferase reporter assay to clarify the targeting relationship between miR-23b-3p and the predicted target genes. The results indicated that overexpression of miR-23b-3p reduced lipid droplet accumulation in goat intramuscular adipocytes, significantly down-regulated the expression levels of adipogenic marker genes AP2, C/EBPα, FASN, and LPL (P < 0.01). In addition, the expressions of C/EBPβ, DGAT2, GLUT4 and PPARγ were significantly downregulated (P < 0.05). After interfering with the expression of miR-23b-3p, lipid droplet accumulation was increased in goat intramuscular adipocytes. The expression levels of ACC, ATGL, AP2, DGAT2, GLUT4, FASN and SREBP1 were extremely significantly up-regulated (P < 0.01), and the expression levels of C/EBPβ, LPL and PPARγ were significantly up-regulated (P < 0.05). It was predicted that PDE4B might be a target gene of miR-23b-3p. The mRNA expression level of PDE4B was significantly decreased after overexpression of miR-23b-3p (P < 0.01), and the interference with miR-23b-3p significantly increased the mRNA level of PDE4B (P < 0.05). The dual luciferase reporter assay indicated that miR-23b-3p had a targeting relationship with PDE4B gene. MiR-23b-3p regulates the differentiation of goat intramuscular preadipocytes by targeting the PDE4B gene.
