China is one of the countries with the highest incidence of gastric cancer.There are differences in epidemiological characteristics,clinicopathological features,tumor biological characteristics,treatment patterns,and drug selection between gastric cancer patients from the Eastern and Western countries.Non-Chinese guidelines cannot specifically reflect the diagnosis and treatment characteristics for the Chinese gastric cancer patients.The Chinese Society of Clinical Oncology(CSCO)arranged for a panel of senior experts specializing in all sub-specialties of gastric cancer to compile,discuss,and revise the guidelines on the diagnosis and treatment of gastric cancer based on the findings of evidence-based medicine in China and abroad.By referring to the opinions of industry experts,taking into account of regional differences,giving full consideration to the accessibility of diagnosis and treatment resources,these experts have conducted experts’consensus judgement on relevant evidence and made various grades of recommendations for the clinical diagnosis and treatment of gastric cancer to reflect the value of cancer treatment and meeting health economic indexes.This guideline uses tables and is complemented by explanatory and descriptive notes covering the diagnosis,comprehensive treatment,and follow-up visits for gastric cancer. 展开更多

The fall armyworm(FAW),Spodoptera frugiperda is one of the most damaging crop pests,and it has become major threat to the food security of many countries.In order to monitor possible invasion of this pest into China,a searchlight trap was established in March 2018 in western Yunnan Province,China,where it has served as the"first station"for many pests that have migrated from Myanmar to China.A number of suspected FAW moths were captured and identified by DNA sequencing.The results showed that the FAW moth was first captured on December 11 and formed its first immigration peak in mid-December 2018.DNA detection revealed that the early invading FAW population was the"corn-strain".The field survey indicated that the pest mainly colonized corn in Pu’er,Dehong and Baoshan areas.Migration trajectory simulation implied that the moths might have mainly come from the eastern area in the mid-latitude region of Myanmar(20-25°N,94-100°E).This case study confirmed the first immigration of FAW into China,and will be helpful for guiding monitoring and management work to control this pest. 展开更多

Background To investigate the clinical features of necrotizing pneumonia (NP) caused by refractoryMycoplasma pneumo-niae pneumonia (RMPP). Methods A retrospective observational study was carried out in patients with NP caused by RMPP who were admitted to our hospital from January 2008 to December 2015, and the clinical manifestations, laboratory data, imaging performances, hospital courses and outcomes were analyzed. Results Twenty-five patients with NP caused by RMPP were collected, with a median age of 5.1 (4.0–7.9) years. The mean duration of fever and hospital stay was 21.0 ± 8.9 and 19.9 ± 9.9 days, respectively. The levels of lactate dehydrogenase (LDH), C-reactive protein, interleukin (IL)-6, IL-10 and interferon-gamma were elevated. Meanwhile, the pleural fluid cell count, LDH and protein were also increased. 80.0% of the patients had pleural effusion;and a high incidence of lobar atelectasis and pulmonary consolidation was found the patients. The mean duration from the onset of symptoms to the discovery of necrotic lesions was 21.0 ± 6.9 days. 80.0% of the patients were administrated corticosteroids, and bronchoalveolar lavage was extracted separately from all patients. Of the 20 patients who presented with pleural effusion, 11 underwent thoracocentesis alone and 2 underwent chest drainage. All patients received prolonged courses of antibiotics (32.2 ± 8.7 days). All patients were dischaged home and recovered without surgical intervention;and chest lesions were resolved or only minimal residual fibrotic changes were residual within 3.0 (2.0–6.0) months. Conclusions Necrotizing pneumonia caused by RMPP is severe, however, self-limiting and reversible. Good outcomes can be achieved with appropriate management. 展开更多

Data transmission rates in optical communication systems are approaching the limits of conventional multiplexing methods.Orbital angular momentum(OAM)in optical vortex beams offers a new degree of freedom and the potential to increase the capacity of free-space optical communication systems,with OAM beams acting as information carriers for OAM division multiplexing(OAM-DM).We demonstrate independent collinear OAM channel generation,transmission and simultaneous detection using Dammann optical vortex gratings(DOVGs).We achieve 80/160 Tbit s^(-1) capacity with uniform power distributions along all channels,with 1600 individually modulated quadrature phase-shift keying(QPSK)/16-QAM data channels multiplexed by 10 OAM states,80 wavelengths and two polarizations.DOVG-enabled OAM multiplexing technology removes the bottleneck of massive OAM state parallel detection and offers an opportunity to raise optical communication systems capacity to Pbit s^(-1) level. 展开更多

Background Hemocoagulase Agkistrodon for injection is a single component thrombin which has passed phases I and II clinical trials. The purpose of this phase III clinical trial was to evaluate the effect of Hemocoagulase Agkistrodon on hemostasis and coagulation in abdominal skin and subcutaneous incisions and to assess the safety of this agent in surgical patients. Methods This is a phase III, prospective, randomized, double-blind, and controlled multicenter clinical trial including 432 consecutive patients randomized into either a study group (injected with hemocoagulase Agkistrodon at 2 U, n=-324) or a control group (injected with hemocoagulase Atrox, n=108). The hemostatic time, hemorrhagic volume, hemorrhagic volume per unit area, blood coagulation, and adverse events were measured and compared between the two groups. Results The mean hemostatic time in the study group was (36.8±18.7) seconds; the hemorrhagic volume was (3.77±3.93) g; and the hemorrhagic volume per unit area was (0.091±0.125) g/cm2. In the control group, the corresponding values were (38.1±19.7) seconds, (4.00±4.75) g, and (0.095±0.101) g/cm2, respectively. No significant difference in values existed between the two groups (P 〉0.05). Blood coagulation results and hepatic and renal function were also similar between the two groups. Adverse events were reported in two cases, but were deemed non-drug-related. Conclusions Hemocoagulase Agkistrodon has good hemostatic and coagulative function and is safe for the use of arresting capillary hemorrhage that occurs while incising the abdomen during surgery. 展开更多

The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST, also called the Guo Shou Jing Telescope) is a special reflecting Schmidt telescope. LAMOST’s special design allows both a large aperture (effective aperture of 3.6 m–4.9 m) and a wide field of view (FOV) (5°). It has an innovative active reflecting Schmidt configuration which continuously changes the mirror’s surface that adjusts during the observation process and combines thin deformable mirror active optics with segmented active optics. Its primary mirror (6.67m×6.05 m) and active Schmidt mirror (5.74m×4.40 m) are both segmented, and composed of 37 and 24 hexagonal sub-mirrors respectively. By using a parallel controllable fiber positioning technique, the focal surface of 1.75 m in diameter can accommodate 4000 optical fibers. Also, LAMOST has 16 spectrographs with 32 CCD cameras. LAMOST will be the telescope with the highest rate of spectral acquisition. As a national large scientific project, the LAMOST project was formally proposed in 1996, and approved by the Chinese government in 1997. The construction started in 2001, was completed in 2008 and passed the official acceptance in June 2009. The LAMOST pilot survey was started in October 2011 and the spectroscopic survey will launch in September 2012. Up to now, LAMOST has released more than 480 000 spectra of objects. LAMOST will make an important contribution to the study of the large-scale structure of the Universe, structure and evolution of the Galaxy, and cross-identification of multiwaveband properties in celestial objects. 展开更多

AIM:To evaluate the role and limitation of fast multiplanarspoiled gradient-recalled (FMPSPGR) MR dynamiccontrast scanning in the follow-up of patients with HCCtreated by transarterial chemoembolization (TACE).METHODS:Twenty-two patients with 24 HCC lesionsconfirmed by biopsy or surgical resection underwentMR imaging in 4-9wks after TACE with a superconducting1.5 T MR scanner, including SE T1WI, T2WI and FMPSPGRdynamic contrast scanning. The signal intensities of alllesions on SE T1WI, T2WI and the enhancement patternson FMPSPGR dynamic contrast scanning were observed,and the comparison was made between MRI findingsand pathological results in ail the cases.RESULTS:Of the 24 lesions, the signal intensities werevarious on SE T1WI and T2WI. On T1WI, 13 lesionsappeared as hyperintense, 4 lesions were isointenseand the other 7 lesions were hypointensese.Histologically, hyperintense lesions showed on T1WIwere viable tumor or hemorrhage; isointensities werecoagulative necrosis or inflammatory infiltration;hypointensities were tumor, liquified necrosis,coagulative necrosis or inflammatory infiltration. OnT2WI, 15 lesions appeared as hyperintense, 3 lesionswere isointense and the other 6 lesions werehypointensese. Hyperintense lesions showed on T2WIwere residuals of viable tumor, hemorrhage, liquefiednecrosis or inflammatory infiltration; isointense lesionswere residuals of viable tumor or inflammatoryinfiltration; hypointense lesions were coagulativenecrosis. On FMPSPGR dynamic contrast scanning, 18of the 24 lesions enhanced on early-phase dynamicscanning conesponding to residuals of viable tumor andthe other 6 lesions had no enhancement at this phasebecause complete necrosis were seen in the histologicexamination. On delayed-phase dynamic scanning, 6lesions had permanent enhancement appeared asinhomogeneous hyperintensity and both residuals ofviable tumor and inflammatory infiltration were foundby histologic examination. 18 lesions were hypointenseat this phase and 8 of them coexisted with peripheralring-like enhancemen 展开更多

There is considerable potential for integrating transarterial chemoembolization(TACE),programmed death-(ligand)1(PD-[L]1)inhibitors,and molecular targeted treatments(MTT)in hepatocellular carcinoma(HCC).It is necessary to investigate the therapeutic efficacy and safety of TACE combined with PD-(L)1 inhibitors and MTT in real-world situations.In this nationwide,retrospective,cohort study,826 HCC patients receiving either TACE plus PD-(L)1 blockades and MTT(combination group,n=376)or TACE monotherapy(monotherapy group,n=450)were included from January 2018 to May 2021.The primary endpoint was progression-free survival(PFS)according to modified RECIST.The secondary outcomes included overall survival(OS),objective response rate(ORR),and safety.We performed propensity score matching approaches to reduce bias between two groups.After matching,228 pairs were included with a predominantly advanced disease population.Median PFS in combination group was 9.5 months(95%confidence interval[CI],8.4-11.0)versus 8.0 months(95%CI,6.6-9.5)(adjusted hazard ratio[HR],0.70,P=0.002).OS and ORR were also significantly higher in combination group(median OS,19.2[16.1-27.3]vs.15.7 months[13.0-20.2];adjusted HR,0.63,P=0.001;ORR,60.1%vs.32.0%;P<0.001).Grade 3/4 adverse events were observed at a rate of 15.8%and 7.5%in combination and monotherapy groups,respectively.Our results suggest that TACE plus PD-(L)1 blockades and MTT could significantly improve PFS,OS,and ORR versus TACE monotherapy for Chinese patients with predominantly advanced HCC in real-world practice,with an acceptable safety profile. 展开更多

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. 展开更多
