1河姆渡遗址动植物遗存的鉴定研究显示文摘河姆渡遗址中发现的动物遗骨,石化程度很轻。据C14测定,第四文化层距今已近七千年。又据微体古生物分析报告,由下至上是由微鹹水沼泽相过渡到淡水陆相的沉积亚粘土与粘土组成。动物遗骨大多发现在第三、四文化层内,尤以第四层为多。这些动物遗骨十分破碎,散布在遗址的各个地方,这种现象,可能是当时人类食用时敲碎的,食用后又随地丢掉的缘故。考虑到文化分层在动物上的意义不大,因此,我们把所有的动物标本放在一起研究讨论。Natural History Section, Chekiang Provincial Museum 1978考古学报1978,,1:65

4Chinese expert consensus statement on the diagnosis and treatment of fulminant myocarditis显示文摘Fulminant myocarditis is primarily caused by infection with any number of a variety of viruses. It arises quickly, progresses rapidly, and may lead to severe heart failure or circulatory failure presenting as rapid-onset hypotension and cardiogenic shock,with mortality rates as high as 50%–70%. Most importantly, there are no treatment options, guidelines or an expert consensus statement. Here, we provide the first expert consensus, the Chinese Society of Cardiology Expert Consensus Statement on the Diagnosis and Treatment of Fulminant Myocarditis, based on data from our recent clinical trial(NCT03268642). In this statement, we describe the clinical features and diagnostic criteria of fulminant myocarditis, and importantly, for the first time,we describe a new treatment regimen termed life support-based comprehensive treatment regimen. The core content of this treatment regimen includes(i) mechanical life support(applications of mechanical respirators and circulatory support systems,including intraaortic balloon pump and extracorporeal membrane oxygenation),(ii) immunological modulation by using sufficient doses of glucocorticoid, immunoglobulin and(iii) antiviral reagents using neuraminidase inhibitor. The proper application of this treatment regimen may and has helped to save the lives of many patients with fulminant myocarditis.Daowen Wang Sheng Li Jiangang Jiang Jiangtao Yan Chunxia Zhao Yan Wang Yexin Ma Hesong Zeng Xiaomei Guo Hong Wang Jiarong Tang Houjuan Zuo Li Lin Guanglin Cui Section of Precision Medicine Group of Chinese Society of Cardiology,Editorial Board of Chinese Journal of Cardiology &Working Group of Adult Fulminant Myocarditis 2019Science China(Life Sciences)2019,62,2:18

8Is inconsistency of α-fetoprotein level a good prognosticator for hepatocellular carcinoma recurrence?显示文摘AIM: To identify the clinical outcomes of hepato-cellular carcinoma (HCC) patients with inconsistent α-fetoprotein (AFP) levels which were initially high and then low at recurrence.METHODS: We retrospectively included 178 patients who underwent liver resection with high preoperative AFP levels (≥ 200 ng/dL). Sixty-nine HCC patients had recurrence during follow-up and were grouped by their AFP levels at recurrence: group Ⅰ, AFP ≤ 20 ng/dL (n = 16); group Ⅱ, AFP 20-200 ng/dL (n = 24); and group Ⅲ, AFP ≥ 200 ng/dL (n = 29). Their preoperative clinical characteristics, accumulated recurrence rate, and recurrence-to-death survival rate were compared. Three patients, one in each group, underwentliver resection twice for primary and recurrent HCC. AFP immunohistochemistry of primary and recurrent HCC specimens were examined.RESULTS: In this study, 23% of patients demon-strated normal AFP levels at HCC recurrence. The AFP levels in these patients were initially high. There were no significant differences in clinical characteristics between the three groups except for the mean recur-rence interval (21.8 ± 14.6, 12.3 ± 7.7, 8.3 ± 6.6 mo, respectively, P < 0.001) and survival time (40.2 ± 19.9, 36.1 ± 22.4, 21.9 ± 22.0 mo, respectively, P = 0.013). Tumor size > 5 cm, total bilirubin > 1.2 mg/dL, vessel invasion, Child classification B, group Ⅲ, and recurrence interval < 12 mo, were risk factors for survival rate. Cox regression analysis was performed and vessel invasion, group Ⅲ, and recurrence interval were independent risk factors. The recurrence inter-val was significant longer in group Ⅰ (P < 0.001). The recurrence-to-death survival rate was significantly bet-ter in group Ⅱ (P = 0.016). AFP staining was strong in the primary HCC specimens and was reduced at recur-rence in group Ⅰ specimens.CONCLUSION: Patients in group Ⅰ with inconsistent AFP levels had a longer recurrence interval and worse recurrence-to-death survival rate than those in group Ⅱ. This clinical presentation may be caused by a delay in the detection of HCC recurrence.Chung-Bao Hsieh, Teng-Wei Chen, Division of General Sur-gery, Tri-Service General Hospital, Taipei 114, Taiwan, China Chung-Bao Hsieh, Kuo-Piao Chung, Graduate Institute of Health Care Organization Administration, National Taiwan University, Taipei 100, Taiwan, China Chi-Ming Chu, Section of Biostatistics and Informatics, De-partment of Epidemiology, School of Public Health, National Defense Medical Center, Taipei 114, Taiwan, ChinaHeng-Cheng Chu, Department of Internal Medicine, Tri-Service General Hospital, Taipei 114, Taiwan, ChinaCheng-Ping Yu, Department of Pathology, Tri-Service General Hospital, Taipei 114, Taiwan, China 2010World Journal of Gastroenterology2010,16,24:11
9散鳞镜鲤与兴国红鲤、龙州镜鲤的杂种优势以及鳞被、体色的遗传显示文摘本研究希望通过鲤鱼品种间杂交出现的杂种优势来提高鲤鱼的产量以及在杂种的后代中选择具有优良的经济性状的类型培育出新的鲤鱼品种。两组杂交的杂种一代具有明显的杂种优势,可以直接应用于渔业生产上并可望获得增产效果。根据对鳞被和体色的遗传特性的研究结果断定散鳞镜鲤与兴国红鲤的杂种二代中出现的红色镜鲤的鳞被和体色是由纯合型隐性基因控制的,可以预期它的后代不再出现分离而可能成为一个稳定的新品种。研究了不同品种及其杂种的血清蛋白聚丙烯酰胺盘状电泳图谱,希望借此作为一种选种的工具。Subgroup of Carp Studies,Section of Fish Breeding,Laboratory of Fish Genetics Breeding,Institute of Hydrobiology,Hupei Province 1975水生生物学集刊1975,5,4:11
10A UNIVERSAL ANALYTIC POTENTIAL-ENERGY FUNCTION BASED ON A PHASE FACTOR显示文摘Using a field equation with a phase factor, a universal analytic potential-energy function applied to the interactions between diatoms or molecules is derived, and five kinds of potential curves of common shapes are obtained adjusting the phase factors. The linear thermal expansion coefficients and Young’s moduli of eleven kinds of face-centered cubic (fcc) metals - Al, Cu, Ag, etc. are calculated using the potential-energy function; the computational results are quite consistent with experimental values. Moreover, an analytic relation between the linear thermal expansion coefficients and Young’s moduli of fcc metals is given using the potential-energy function. Finally, the force constants of fifty-five kinds of diatomic moleculars with low excitation state are computed using this theory, and they are quite consistent with RKR (Rydberg-Klein-Rees) experimental values.C.F.

11Neutral Red Retention by Earthworm Coelomocytes: A Biomarker of Cadmium Contamination in Soil显示文摘The earthworm Metaphire posthuma were used as a model to assess the toxic potential of cadmium incorporated into the soil by environmental or human activities. The retention period of neutral red in the lysosomes of the coelomocytes was used as a biomarker. The viability of harvested coelomocytes by a non_invasive extrusion protocol was 93% with no alteration by the dye during experimentation. The control cells retained dye for 119 and 121 min in normal soil and KCl, respectively, whereas a linear decline in the retention time in the treated earthworm coelomocytes was observed. This illustrated that the presence of cadmium caused damage to the lysosomes of the coelomocytes.S. K. GUPTA Cell Biology Section, Industrial Toxicology Research Centre, M. G. Marg, P. B.

13细鳞斜颌鲴的养殖及其生物学研究显示文摘细鳞斜颌鲴是在我国分布较广而又为群众所喜爱的一种野生经济鱼类。这种鱼在某些天然水体中可成为优势种群,产量较大,最高可以占总渔获量的50%以上。但有许多水体中却没有这种鱼或数量不大。通过试验和研究,我们已能对这种鱼进行大规模的人工繁殖和苗种培育,近年来,已将数万尾大规格鱼种投放到一原来只投放“家鱼”(泛指鲩、青、鲢、鳙,以下均同)的水库中,并将检验其增产效果。实践证明斜颌鲴在池塘中与现有“家鱼”混养时,非但不影响“家鱼”的生长,并可使池塘总产量增加10%以上;原因是这种鱼主要以其他养殖鱼类尚未利用或未能充分利用的腐屑、腐泥和着生藻类为食物。该鱼头两年生长较快,两周年可达一市斤左右,并第一次达到性成熟,这种规格的鱼上市就是经济价值高的优良食用鱼。因其在池塘中易于捕捞,故也是丰产塘中轮捕轮放的好对象。按普通“家鱼”种的培育方法当年鱼可养成4寸左右,第二年底都能在半斤以上,大的可达8两半。由于该鱼头小肉多而味美,故即使2—3两重的鱼在市场上也受到顾客的欢迎。本文还介绍了养殖这种鱼的方法及其有关的生物学资料,并讨论了在天然水体中促使这种鱼增产的可能途径。Administrative Board of the Tao-Yuan-Ho Reservoir,Hupei Province Section of Introduction Acclimation,Laboratory of Fish Genetics Breeding,Institute of Hydrobiology,Hupei Province 1975水生生物学集刊1975,5,4:10

16Dual Gabriel theorem with applications显示文摘We introduce the quiver of a bicomodule over a cosemisimple coalgebra. Applying this to the coradical C0 of an arbitrary coalgebra C, we give an alternative definition of the Gabriel quiver of C, and then show that it coincides with the known Ext quiver of C and the link quiver of C. The dual Gabriel theorem for a coalgebra with a separable coradical is obtained, which generalizes the corresponding result for a pointed coalgebra. We also give a new description of C1 = C0 ∧X C0 of any coalgebra C, which can be regarded as a generalization of the first part of the well-known Taft-Wilson Theorem for pointed coalgebras. As applications, we give a characterization of locally finite coalgebras via their Gabriel quivers, and a property of the Gabriel quiver of a quasi-coFrobenius coalgebra.CHEN Xiaowu, HUANG Hualin & ZHANG Pu Department of Mathematics, University of Science and Technology of China, Hefei 230026, China USTC Shanghai Institute for Advanced Studies, Shanghai 201315, China Mathematical Section, the Abdus Salam ICTP, Strada Costiera 11, Trieste 34014, Italy Department of Mathematics, Shanghai Jiao Tong University, Shanghai 200030, China 2006Science China Mathematics2006,49,1:6
17Comparison of PBDE congener profiles and concentration levels in human specimens from China and the US and identification of human exposure sources显示文摘In an effort to investigate the status of human exposure to PBDEs in China,available monitoring data in human specimens(including breast milk,serums,and blood) was collected from the general population as well as specific groups that are occupationally exposed.PBDEs exposure profiles and concentration levels were compared with their counterparts in the United States of America.It was found that PBDE burdens in general Chinese population are one order lower and have different congener profiles from that in the US,showing higher percentages of BDE-28 or BDE-153 in human specimens from China.Workers and residents in electronic wastes recycling regions or areas of commercial PBDE manufacturing have the highest PBDE exposure levels reported worldwide,which are close or higher than the exposure levels of the general population in the US. Highly brominated congeners,such as BDE-207 and 209,are among the major PBDE congeners,and BDE-209 has the highest percentage(above 50%) for all occupational populations studied.Principal components analysis(PCA) demonstrates that the exposure of the general population in the US is closely related to penta-BDE while the human burden in China is not.The PBDE in indoor air(gas phase) in the US is highly correlated with the PBDE burden in the general population in the US,indicating a major exposure pathway.For the occupationally exposed populations in China,the congener profiles are closely related to the commercial deca-BDE products.Examination of exposure profiles for general and occupational populations in China suggests that it is essential to include more highly brominated congeners,such as BDE-207 and 209,in future human exposure studies,in order to assess the real burdens and profiles of PBDEs exposure in China.Strict pollution prevention and occupational protection procedures are in need in China to avoid the PBDE contamination problem that has occurred in the US.SHE JianWen 1,SHE YiFan 2 &SONG WenLu 2 1 Biochemistry Section,Environmental Health Laboratory Branch,California Department of Public Health,Richmond,CA 94804,USA 2Chemistry Section,Food and Drug Laboratory Branch,California Department of Public Health,Richmond,CA 94804,USA 2010Science China Chemistry2010,53,5:5
