Either 500 mg or 750 mg of oral nemonoxacin taken once daily for 7-10 days demonstrated high clinical and bacteriological success rates in Chinese adult patients with CAP. Nemonoxacin at 500 mg once daily for 7-10 days is recommended for future Phase III clinical trials. ClinicalTrials.gov identifier: NCT01537250.

BackgroundChronic obstructive pulmonary disease (COPD) is a chronic lung inflammatory disease which has a close relationship with aging. Genome-wide analysis reveals that DNA methylation markers vary obviously with age. DNA methylation variations in peripheral blood have the potential to be biomarkers for COPD. However, the specific DNA methylation of aging-related genes in the peripheral blood of COPD patients remains largely unknown.MethodsFirstly, 9 aging-related differentially expressed genes (DEGs) in COPD patients were screened out from the 25 aging-related genes profile through a comprehensive screening strategy. Secondly, qPCR and multiple targeted bisulfite enrichment sequencing (MethTarget) were used to detect the mRNA level and DNA methylation level of the 9 differentially expressed genes in the peripheral blood of 60 control subjects and 45 COPD patients. The candidate functional CpG sites were selected on the basis of the regulation ability of the target gene expression. Thirdly, the correlation was evaluated between the DNA methylation level of the key CpG sites and the clinical parameters of COPD patients, including forced expiratory volume in one second (FEV1), forced expiratory volume in one second as percentage of predicted volume (FEV1%), forced expiratory volume/ forced vital capacity (FEV/FVC), modified British medical research council (mMRC) score, acute exacerbation frequency and the situation of frequent of acute aggravation (CAT) score. Lastly, differentially methylated CpG sites unrelated to smoking were also determined in COPD patients.ResultsOf the 9 differentially expressed aging-related genes, the mRNA expression of 8 genes were detected to be significantly down-regulated in COPD group, compared with control group. Meanwhile, the methylated level of all aging-related genes was changed in COPD group containing 219 COPD-related CpG sites in total. Notably, 27 CpG sites of FOXO3 gene showed a lower False Discovery Rate (FDR) and higher methylation difference values. Also, some variable DNA methylation is associated with the severity of COPD. Additionally, of the 219 COPD-related CpG sites, 147 CpG sites were not related to smoking.ConclusionThese results identified that the mRNA expression and DNA methylation level of aging-related genes were changed in male COPD patients, which provides a molecular link between aging and COPD. The identified CpG markers are associated with the severity of COPD and provide new insights into the prediction and identification of COPD.

It has been nearly 40 years since the reform and opening up of Mainland China. The mental health services system has developed rapidly as a part of the profound socioeconomic changes that ensued. However, its development has not been as substantial as other areas of medical care. For the current qualitative systematic review, we searched databases, including China Biology Medicine disc, Weipu, China National Knowledge Infrastructure, Wanfang digital periodical full text data, China's important newspaper full text database, China Statistical Yearbook database, etc. The content of primary research, literature, and policy papers about the evolution and development of Chinese mental health services was systemically reviewed and analysed by using thematic analysis. Two main themes relative to the necessity and feasibility of reforming the current mental health services system emerged. We discuss 5 corresponding subthemes under the umbrella of the necessity of improving the current treatment, rehabilitation, prevention, and service systems and 7 requirements for the feasibility of reforming the current system. We conclude that as the development of the Chinese economy and the spirit of humanistic care continue, the improvement and reformation of the mental health services system are both necessary and feasible.
