Objective To compare the efficacy and safety of naphthoquine, artemisinine and a combination of the two drugs in the treatment of faciparum malaria. Methods Of 230 patients, 100 patients were treated with combined regime (Co-NQ), 100 patients were treated with naphthoquine (NQ) and 30 patients were treated with artemisinine (QHS). All patients were hospitalized for 7 days and followed up for 28 days. Results The mean fever clearance time for Co-NQ, NQ, and QHS was (17.5 ?12.3)h, (32.7?17.7)h and (18.1?9.7)h respectively; the mean parasite clearance time was (30.0?8. 8)h,(45.5?10.0)h and (29.1?6.0)h respectively; and the 28 days cure rate was 97.0% ,100.0% and 66.7% respectively. Conclusion The Co-NQ possesses benefits of both naphthoquine and artemisinine, acting rapidly, with a short course of only one dose and a high cure rate. The regime is well tolerated by patients.

Results showed that its action was satisfactory.Theclinical effects of all three kinds of disease were betterthan that of the control group,especially on the im-provement of deficiency of blood and Qi(P

Objective To strengthen the management of the handover and transfer process of surgical patients in the department of thoracic surgery, improve surgery and transfer efficiency and ensure transfer safety. Methods In 2015, Shanghai Chest Hospital, Shanghai Jiaotong University reconstructed a nursing team by building the surgical handover and transfer process, analyzed the needs of transferees and transferees and the factors contributing to low efficiency and high safety risks in transfer, rebuilt, optimized and standardized the existing surgical handover and transfer process in the department of thoracic surgery, and enhanced relevant training after the process was rebuilt. Totally 1591 transferred patients who received thoracic surgery between January and March 2015 were selected as a control group, while 2126 patients who received thoracic surgery from January to March 2016 were selected as an observation group. The handover and transfer efficiency before and after the rebuilt process was then compared, including time of handover delay for the first surgery, time of delay for consecutive surgery, the number of patients detained in operation rooms postoperatively as well as doctors and nurses′ satisfaction to the rebuilt process.Results After the process was rebuilt, the delay rate for the first surgery was 1.7%; the delay rate for consecutive surgery was 2.7%; the retention rate in recovery rooms was 2.8%, lower than the figures before the process was rebuilt (χ2=24.059, 63.146, 53.675;P＜0.01). Doctors and nurses′ satisfaction to the rebuilt process was ＞90%.Conclusions Management optimization by process reengineering helps to improve surgical handover and transfer efficiency, safety as well as doctors and nurses′ satisfaction.

Histone H3 lysine 4 trimethylation (H3K4me3) is well known to occur in the promoter region of genes for transcription activation.However,when investigating the H3K4me3 profiles in the mouse cerebrum and testis,we discovered that H3K4me3 also has a significant enrichment at the 3' end of actively transcribed (sense) genes,named as 3′-H3K4me3.3′-H3K4me3 is associated with ～15％ of protein-coding genes in both tissues.In addition,we examined the transcriptional initiation signals including RNA polymerase II (RNAPII)binding sites and 5′-CAGE-tag that marks transcriptional start sites.Interestingly,we found that 3′-H3K4me3 is associated with the initiation of antisense transcription.Furthermore,3′-H3K4me3 modification levels correlate positively with the antisense expression levels of the associated sense genes,implying that 3′-H3K4me3 is involved in the activation of antisense transcription.Taken together,our findings suggest that H3K4me3 may be involved in the regulation of antisense transcription that initiates from the 3′ end of sense genes.In addition,a positive correlation was also observed between the expression of antisense and the associated sense genes with 3'-H3K4me3 modification.More importantly,we observed the 3'-H3K4me3 enrichment among genes in human,fruitfly and Arabidopsis,and found that the sequences of 3'-H3K4me3-marked regions are highly conserved and essentially indistinguishable from known promoters in vertebrate.Therefore,we speculate that these 3'-H3K4me3-marked regions may serve as potential promoters for antisense transcription and 3′-H3K4me3 appear to be a universal epigenetic feature in eukaryotes.Our results provide a novel insight into the epigenetic roles of H3K4me3 and the regulatory mechanism of antisense transcription.

The global features of H3K4 and H3K27 trimethylations (H3K4me3 and H3K27me3) have been well studied in recent years,but most of these studies were performed in mammalian cell lines.In this work,wegenerated the genome-wide maps of H3K4me3 and H3K27me3 of mouse cerebrum and testis using ChlP-seq and their high-coverage transcriptomes using ribominus RNA-seq with SOLiD technology.We examined the global patterns of H3K4me3 and H3K27me3 in both tissues and found that modifications are closely-associated with tissue-specific expression,function and development.Moreover,we revealed that H3K4me3 and H3K27me3 rarely occur in silent genes,which contradicts the findings in previous studies.Finally,we observed that bivalent domains,with both H3K4me3 and H3K27me3,existed ubiquitously in both tissues and demonstrated an invariable preference for the regulation of developmentally-related genes.However,the bivalent domains tend towards a "winner-takes-all" approach to regulate the expression of associated genes.We also verified the above results in mouse ES cells.As expected,the results in ES cells are consistent with those in cerebrum and testis.In conclusion,we present two very important findings.One is that H3K4me3 and H3K27me3 rarely occur in silent genes.The other is that bivalent domains may adopt a "winner-takes-all" principle to regulate gene expression.
