Background We have previously developed and characterized a monoclonal anti-idiotype antibody, designated 6B 11, which mimics an ovarian carcinoma associated antigen OC166-9 and whose corresponding monoclonal antibody is COC166-9 （Abl）. In this study, we evaluate the humoral immune responses induced by the fusion protein 6B11 single-chain variable fragment （scFv）/human granulocyte macrophage colony-stimulating factor （hGM-CSF） and 6B 1 lscFv in BALB/c mice. Methods The fusion protein 6B 11 scFv/hGM-CSF was constructed by fusing a recombinant single-chain variable fragment of 6B11scFv to GM-CSE BALB/c mice were administrated by 6B11scFv/hGM-CSF and 6B11scFv, respectively. Results The fusion protein 6B11scFv/hGM-CSF retained binding to the anti-mouse F（ab）2＇ and was also biologically active as measured by proliferation of human GM-CSF dependent cell TF1 in vitro. After immunization with the 6B11scFv/hGM-CSF and 6BllScFv, BALB/c mice showed significantly enhanced Ab3 antibody responses to 6B11 scFv/hGM-CSF compared with the 6B11 scFv alone. The level of Ab3 was the highest after the first week and maintained for five weeks after the last immunization. Another booster was given when the Ab3 titer descended, and it would reach to the high level in a week. Conclusion The fusion protein 6B11scFv/hGM-CSF can induce humoral immunity against ovarian carcinoma in vivo. We also provide the theoretical foundation for the application of the fusion protein 6B11 scFv/hGM-CSF for active immunotherapy of ovarian cancer.

Various SARS-CoV-2-related coronaviruses have been increasingly identified in pangolins,showing a potential threat to humans.Here we report the infectivity and pathogenicity of the SARS-CoV-2-related virus,PCoV-GX/P2V,which was isolated from a Malayan pangolin(Manis javanica).PCoV-GX/P2V could grow in human hepatoma,colorectal adenocarcinoma cells,and human primary nasal epithelial cells.It replicated more efficiently in cells expressing human angiotensin-converting enzyme 2(hACE2)as SARS-CoV-2 did.After intranasal inoculation to the hACE2-transgenic mice,PCoV-GX/P2V not only replicated in nasal turbinate and lungs,but also caused interstitial pneumonia,characterized by infiltration of mixed inflammatory cells and multifocal alveolar hemorrhage.Existing population immunity established by SARS-CoV-2 infection and vaccination may not protect people from PCoV-GX/P2V infection.These findings further verify the hACE2 utility of PCoV-GX/P2V by in vivo experiments using authentic viruses and highlight the importance for intensive surveillance to prevent possible cross-species transmission.

We report the detection of aγ-ray bubble spanning at least 100deg2 in ultra-high energy(UHE)up to a few PeV in the direction of the star-forming region Cygnus X,implying the presence super PeVatron(s)accelerating protons to at least 10 PeV.A log-parabola form with the photon indexΓ(E)=(2.71±0.02)+(0.11±0.02)×log10(E/10 TeV)is found fitting the gamma-ray energy spectrum of the bubble well.UHE sources,“hot spots”correlated with very massive molecular clouds,and a quasi-spherical amorphousγ-ray emitter with a sharp central brightening are observed in the bubble.In the core of~0.5°,spatially associating with a region containing massive OB association(Cygnus OB2)and a microquasar(Cygnus X-3),as well as previously reported multi-TeV sources,an enhanced concentration of UHEγ-rays is observed with 2 photons at energies above 1 PeV.The general feature of the bubble,the morphology,and the energy spectrum,are reasonably reproduced by the assumption of a particle accelerator in the core,continuously injecting protons into the ambient medium.

The full array of the Large High Altitude Air Shower Observatory(LHAASO)has been in operation since July 2021.For its kilometer-square array(KM2A),we optimized the selection criteria for very high and ultrahigh energyγ-rays using data collected from August 2021 to August 2022,resulting in an improvement in significance of the detection in the Crab Nebula of approximately 15%,compared with that of previous cuts.With the implementation of these new selection criteria,the angular resolution was also significantly improved by approximately 10%at tens of TeV.Other aspects of the full KM2A array performance,such as the pointing error,were also calibrated using the Crab Nebula.The resulting energy spectrum of the Crab Nebula in the energy range of 10-1000 TeV are well fitted by a log-parabola model,which is consistent with the previous results from LHAASO and other experiments.

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.

Introduction One of main scientiﬁc goals of the Large High Altitude Air Shower Observatory(LHAASO)is to accurately measure the energy spectra of different cosmic ray compositions around the‘knee’region.The Wide Field-of-View(FoV)Cherenkov Telescope Array(WFCTA),which is one of the main detectors of LHAASO and has 18 telescopes,is built to achieve this goal.Multiple telescopes are put together and point to connected directions for a larger FoV.Method Telescopes are deployed spatially as close as possible,but due to their own size,the distance between two adjacent telescopes is about 10 m.Therefore,the Cherenkov lateral distribution and the parallax between the two telescopes should be considered in the event building process for images crossing over the boundaries of FoVs of the telescopes.An event building method for Cherenkov images measured by multiple telescopes of WFCTA is developed.The performance of the shower measurements using the combined images is evaluated by comparing with showers that are fully contained by a virtual telescope in simulation.Results and conclusion It is proved that the developed event building process can help to increase the FoV of WFCTA by 30%while maintaining the same reconstruction quality,compared to the separate telescope reconstruction method.

目的调查2005年7月中旬四川省资阳市一家医院报告5例以败血症休克为主要临床表现的聚集性病例的病因。方法建立了病例主动发现、报告的加强监测系统,根据病例的流行病学暴露史和临床表现进行临床诊断;采集患者标本进行细菌分离培养和生化反应鉴定,应用PCR方法对猪链球菌2型的种属和毒力基因进行检测和序列测定;与当地往年报告的流行性脑脊髓膜炎发病数进行比较。结果2005年6月10日至8月21日,四川省共报告了68例实验室确诊人感染猪链球菌病例,发病前都有屠宰、洗切、加工等病(死)猪的直接暴露史。其中26例(38%)表现为中毒性休克综合征,15例(58%)死亡。其他病例临床表现为轻型败血症或脑膜炎。分离菌株应用PCR方法检测猪链球菌2型的种属和毒力基因(tuf、16S rRNA、cps2J、mrp、sly、ef)均为阳性。同期还报告了136例有相似暴露史,但缺乏实验室确诊依据的临床诊断病例。结论证实该起发生在四川省部分农村地区直接暴露于病(死)猪后的疾病为猪链球菌2型感染暴发。推测这种罕见的、表现为高病死率的中毒性休克综合征可能是由于感染某种高致病性菌株循环所致。
