Objective:To research the curative effect of moxifloxacin solution atomization inhalation in the treatment of chronic obstructive pulmonary disease (COPD) combined with respiratory failure.Methods:94 cases of COPD patients combined with respiratory failure from May 2014 to May 2016 were selected and divided into the control group(n=47) and the research group (n=47) acording to the lottery method,the control group received routine treatment,while the research group was treated based on the control group with moxifloxacin solution inhalation treatment.The curative effect,serum tumor necrosis factor-α(TNF-α),c-reactive protein (CRP) and interleukin 10 (IL-10),creatine phosphokinase (CK),aspertate aminotransferase (AST) levels,the blood oxygen partial pressure (PaO2),CO2 partial pressure (PaCO2),APACHE Ⅱ score and occurrence of adverse reactions were compared between two groups.Results:After treatment,the total effective rate of research group was higher than that of the control group (P＜0.05).The serum levels of TNF alpha,CRP,PaCO2,CK,AST,APACHE Ⅱ score of research group were evidently lower than those of the control group (P＜0.05).The serum levels ofIL-10,PaO2 of research group were evident higher than those of the control group (P＜0.05).The occurrence of adverse reactions showed no differences between the two groups (P＞0.05).Conclusion:Moxifloxacin solution atomization inhalation was effective in the treatment of COPD combined with respiratory failure,which might be related to the inhibition of inflammatory response,and improvment of breath.

Objective To explore the functional orientation of township hospitals in developed areas to achieve goals of the ongoing health reform.Methods Two rounds of Delphi consultation was made among 18 experts from around the country to learn the degree of importance of every function.Results The experts' average seniority of service in their fields was 23.28±10.41 years.The positivity coefficients of the two-round consultation were 100％.Kendall' S coefficients of the two-round consultation were 0.226 and 0.265 (p＜0.01).These data are of statistical importance,suggesting consensus among these experts and the consultation meeting the needs of forecast.In these consultation,seven class-1 functions and and 27 class-2 functions were determined.Medical services and public health services account for similar proportion of work of township hospitals.Conclusion The functional orientation was feasible and forward looking,for reference of township hospitals in developed areas.

Objective: To observe the effects of fecal microbiota transplantation (FMT) on acute lung injury (ALI) induced by lipopolysaccharide (LPS) in rats and to investigate the possible mechanism in order to provide new thoughts for the treatment of acute lung injury. Methods: Forty-five adult healthy male SPF level SD rats were randomly divided into three groups of normal saline (NS), LPS and FMT with 15 in each group. ALI was induced by intraperitoneal injection of rats with 5 mg/kg of LPS. The FMT group was given 10 ml/kg of fecal microbiota solution intervention (twice a day for two consecutive days) after ALI induction. Five rats in each group were randomly selected and sacrificed at 24 h, 48 h and 72 h after intervention. Pathological changes in lung tissues were examined with hematoxylin and eosin (HE) staining and pathological scores were assessed. Right lung samples were weighed to measure wet/dry (W/D) ratios. Abdominal aorta blood samples were collected for PaO₂ analysis. The levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin 6 (IL-6) in bronchoalveolar lavage fluid (BALF) were detected by enzyme linked immunosorbent assay (ELISA). Expression of transforming growth factor-β (TGF-β) and intracellular signal transduction protein Smads (Smad3 and Smad7) at mRNA level was analyzed by reverse transcription-polymerase chain reaction (RT-PCR). Expression of ERK1/2 and p-ERK1/2 at protein level was detected by Western blot (WB). Rat fecal samples were collected to extract DNA and the PCR products of V3 and V4 regions were sequenced by Illumina MiSeq. Bioinformatics analysis on microbiota was conducted with Illumina MiSeq based on operational taxonomic unit (OTU) clustering. Results: Compared with the NS group, the LPS group showed significantly widened alveolar septa, massive inflammatory cell infiltration and some alveolar collapse in lung tissues. Compared with the LPS group, the FMT group showed significantly alleviated inflammatory cell infiltration, reduced swelling in pulmonary interstitial tissues, and less damage to pulmonary structure. Compared with the NS group, the W/D lung ratio, PaO₂ concentration and TNF-α, IL-1 and IL-6 levels in BALF in the LPS group significantly increased at 24 h after intervention and then gradually decreased, but still higher than those in the NS group (P<0.05). The W/D lung ratio, PaO2 concentration and TNF-α, IL-1 and IL-6 levels in BALF of the FMT group were significantly lower than those of the LPS group (P<0.05). Compared with the NS group, the expression of TGF-β1 and Smad3 at mRNA level in lung tissues increased at all time points in the LPS group, while the expression of Smad7 at mRNA level decreased (P<0.05). The expression of TGF-β1 and Smad3 at mRNA level in the FMT group were significantly lower than that in the LPS group (P<0.05), while the expression of Smad7 at mRNA level was higher (P<0.05). Compared with the NS group, p-ERK expression significantly increased in the LPS group with the highest expression at 24 h and gradually decreased at 48 h and 72 h (P<0.05). The expression of p-ERK in the FMT group was significantly lower than that in the LPS group (P<0.05). Results of the intestinal microbiota sequencing revealed 1 362 OTU in the NS group, 1 443 OTU in the LPS group and 1 510 OTU in the FMT group. There were 336 OTU shared by them accounting for 26.4%. The constitution of intestinal microbiota in the LPS group was significantly different with that of normal rats and characterized by high diversity with increased Firmicutes/Bacteroidetes ratio and decreased gene abundance of intestinal microbiota. After the intervention of fecal bacteria transplantation, the constitution of intestinal microbiota in the FMT group was similar to that of the NS group, showing decreased Firmicutes/Bacteroidetes ratio and increased gene abundance of the bacterial community (P<0.05). Conclusions FMT might inhibit immune inflammation, reduce the production and secretion of inflammatory markers in the body, alleviate alveolar epithelial damage and abnormal repair through regulating intestinal microbiota and TGF-β1/Smads/ERK pathway to improve the LPS-induced endotoxic ALI in rats.

Objective:To explore combined detection of mad2 with anti-nuclear mitotic spindle apparatus antibody(MSA)and anti-centromere antibody(ACA)and their clinical value for the diagnosis of small cell lung cancer(SCLC).Methods:One hundred and twen-ty SCLC patients,110 non-small cell lung cancer(NSCLC)patients,and 115 pulmonary nodule(PN)patients were enrolled in this study. The expression of mad2 was analyzed by qt-PCR.MSA and ACA were detected by indirect immunofluorescence(IIF)staining.Results:mad2 was overexpressed in SCLC and NSCLC samples(P<0.05).There were significant differences between the results obtained for SCLC and NSCLC samples by qt-PCR(P<0.05).AUC in ROC curve for mad2 expression was 0.799 with an intermediate diagnostic value. In the correlative analysis,the odds ratio of MSA and ACA was 6.94 and 5.60,respectively.In the correlation analysis,Kappa value of mad2 with MSA was 0.49,and Kappa value of mad2 with ACA was 0.42.In the parallel analysis,the sensitivity and specificity was 83.31% and 79.34%,respectively,while the Youden Index was 0.62.Moreover,in the serial analysis,the sensitivity and specificity was 65.32% and 93.35%,respectively,and the Youden Index was 0.59.Conclusions:In comparison with the NSCLC and PN samples,mad2 was overexpressed in SCLC samples.Therefore,mad2 ought to play a critical role in the pathology of SCLC.The combined expression of mad2 with MSA and ACA may contribute to enhancing the sensitivity and specificity of detection;this expression may allow early diag-nosis and clinical diagnosis of SLCC and may be a promising treatment for SCLC.
