Melastomataceae has abundant morphological diversity with high economic and ornamental merit in Myrtales. The phylogenetic position of Myrtales is still contested. Here, we report the chromosome-level genome assembly of Melastoma dodecandrum in Melastomataceae. The assembled genome size is299.81 Mb with a contig N50 value of 3.00 Mb. Genome evolution analysis indicated that M. dodecandrum,Eucalyptus grandis, and Punica granatum were clustered into a clade of Myrtales and formed a sister group with the ancestor of fabids and malvids. We found that M. dodecandrum experienced four whole-genome polyploidization events: the ancient event was shared with most eudicots, one event was shared with Myrtales, and the other two events were unique to M. dodecandrum. Moreover, we identified MADS-box genes and found that the AP1-like genes expanded, and AP3-like genes might have undergone subfunctionalization. The SUAR63-like genes and AG-like genes showed different expression patterns in stamens, which may be associated with heteranthery. In addition, we found that LAZY1-like genes were involved in the negative regulation of stem branching development, which may be related to its creeping features. Our study sheds new light on the evolution of Melastomataceae and Myrtales, which provides a comprehensive genetic resource for future research.

In December 2019, a new type viral pneumonia cases occurred in wuhan, Hubei Province;and then named "2019 novel coronavirus(2019-nCoV)" by the World Health Organization(WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world’s attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development;we also added the first-hand management data of Zhongnan Hospital of wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control(including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV.

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

Background:Adequate evaluation of degrees of liver cirrhosis is essential in surgical treatment of hepatocellular carcinoma(HCC)*** impact of the degrees of cirrhosis on prediction of post-hepatectomy liver failure(PHLF)remains poorly *** study aimed to construct and validate a combined pre-and intra-operative nomogram based on the degrees of cirrhosis in predicting PHLF in HCC patients using prospective multi-center’s ***:Consecutive HCC patients who underwent hepatectomy between May 18,2019 and Dec 19,2020 were enrolled at five tertiary *** cirrhotic severity scoring(CSS)and intra-operative direct liver stiffness measurement(DSM)were performed to correlate with the Laennec histopathological grading *** performances of the pre-operative nomogram and combined pre-and intra-operative nomogram in predicting PHLF were compared with conventional predictive models of ***:For 327 patients in this study,histopathological studies showed the rates of HCC patients with no,mild,moderate,and severe cirrhosis were 41.9%,29.1%,22.9%,and 6.1%,*** CSS or DSM was closely correlated with histopathological stages of ***-three(10.1%)patients developed *** 30-and 90-day mortality rates were 0.9%.Multivariate regression analysis showed four pre-operative variables[HBV-DNA level,ICG-R15,prothrombin time(PT),and CSS],and one intra-operative variable(DSM)to be independent risk factors of *** pre-operative nomogram was constructed based on these four pre-operative variables together with total *** combined pre-and intra-operative nomogram was constructed by adding the intra-operative *** pre-operative nomogram was better than the conventional models in predicting *** prediction was further improved with the combined pre-and intra-operative ***:The combined pre-and intra-operative nomogram further improved prediction of PHLF when compared with the pre-operat
