1A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV) infected pneumonia(standard version)显示文摘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.Ying-Hui Jin Lin Cai Zhen-Shun Cheng Hong Cheng Tong Deng Yi-Pin Fan Cheng Fang Di Huang Lu-Qi Huang Qiao Huang Yong Han Bo Hu Fen Hu Bing-Hui Li Yi-Rong Li Ke Liang Li-Kai Lin Li-Sha Luo Jing Ma Lin-Lu Ma Zhi-Yong Peng Yun-Bao Pan Zhen-Yu Pan Xue-Qun Ren Hui-Min Sun Ying Wang Yun-Yun Wang Hong Weng Chao-Jie Wei Dong-Fang Wu Jian Xia Yong Xiong Hai-Bo Xu Xiao-Mei Yao Yu-Feng Yuan Tai-Sheng Ye Xiao-Chun Zhang Ying-Wen Zhang Yin-Gao Zhang Hua-Min Zhang Yan Zhao Ming-Juan Zhao Hao Zi Xian-Tao Zeng Yong-Yan Wang Xing-Huan Wang 2020Military Medical Research2020,7,1:161
2Paleogene-Neogene stratigraphic realm and sedimentary sequence of the Qinghai-Tibet Plateau and their response to uplift of the plateau显示文摘Based on the data of 1:250000 geological mapping completed by CGS and the previous literature of the Cenozoic strata, 98 remnant basins and 5 stratigraphic realms with 13 stratigraphic subrealms have been recognized on the Qinghai-Tibet Plateau and its adjacent area. Through the research of the types of remnant basins, tectonic setting, stratigraphic sequence and sedimentary characteristics, contact relationship between the strata, the formation time and evolution history of sediments, we divided the uplift process and sedimentary response of the Qinghai-Tibet Plateau into 3 stages and 8 sub-stages, namely, subduction-collision uplift stage (65-34 Ma) with three sub-stages, intercontinental convergence and compressive uplift stage (34-13 Ma) with three sub-stages, and intercontinental isostatic adjustment uplift stage (since 13 Ma) with two sub-stages.ZHANG KeXin WANG GuoCan JI JunLiang LUO ManSheng KOU XiaoHu WANG YueMing XU YaDong CHEN FenNing CHEN RuiMing SONG BoWen ZHANG JianYu LIANG YinPing 2010Science China Earth Sciences2010,53,9:49

4The Status and Associated Factors of Successful Aging among Older Adults Residing in Longevity Areas in China显示文摘Objective This study aims to assess the status of successful aging(SA) in longevity areas in China and explore multiple factors associated with SA among the young-old and oldest-old. Methods A total of 2296 elderly people aged 65 and older were interviewed in the longevity areas sub-sample of the Chinese Longitudinal Healthy Longevity Survey(CLHLS) in 2012. Baseline assessments included a researcher-administered questionnaire, physical examination, and laboratory testing. A logistic regression model was used to identify factors associated with SA. Results The prevalence of SA was 38.81% in the CLHLS in 2012. There were significant differences between ages groups, with SA compromising 56.85% among ≥65 years group and 20.31% among ≥100 years group(χtrend2=126.73, P<0.01). The prevalence of SA among females was 33.59%, which was significantly lower than that among males(45.58%)(χ2gender=33.65, P<0.05). In the regression analysis, having anemia(OR=0.744, 95% CI: 0.609-0.910), poor lifestyle(OR=0.697, 95% CI: 0.568-0.854), poor sleep quality(OR=0.558, 95% CI: 0.456-0.682), and central obesity(OR=0.684, 95% CI: 0.556-0.841) were the main factors associated with SA. The promoting SA rate decreased as age increased, and the group of 65-79 years had higher odds than the other age group. Conclusion Preventing central obesity, improving sleep quality and promoting healthy lifestyle may contribute to achieve SA among the elderly.SHI Wen Hui ZHANG Hong Yan ZHANG Juan LYU Yue Bin Melanie Sereny Brasher YIN Zhao Xue LUO Jie Si HU Dong Sheng FEN Lei SHI Xiao Ming 2016Biomedical and Environmental Sciences2016,29,5:10
5Micro RNA profiles and potential regulatory pattern during the early stage of spermatogenesis in mice显示文摘Spermatogenesis is a complicated and poorly understood process that relies on the precise regulation of the self-renewal and differentiation of spermatogonia. In many organisms, micro RNAs(mi RNAs) are involved in multiple developmental processes as critical regulators of transcriptional and post-transcriptional gene silencing. This study investigated the expression pattern of mi RNAs in type B spermatogonia cells(BSc) and primary spermatocytes(PSc) of mice, using a high-throughput small RNA sequencing system. The results revealed that the expression levels of Let-7 family mi RNAs were remarkably high in both cell types. Furthermore, the expression levels of mi R-21, mi R-140-3p, mi R-103, mi R-30 a, mi R-101 b and mi R-99 b were decreased during the transformation from BSc to PSc. These mi RNAs target vital genes that participate in apoptosis, cell proliferation and differentiation, junction assembly and cell cycle regulation. These results highlight the indispensable role of mi RNAs in spermatogenesis.LUO MengMeng HAO LiLi HU Fen DONG YaNan GOU LiXia ZHANG WenDian WANG Xin ZHAO YuHui JIA MengChun HU SongNian ZHANG XiuJun 2015Science China(Life Sciences)2015,58,5:6
6Food Frequency Questionnaire for Chinese Children Aged 12-17 Years: Validity and Reliability显示文摘Objective The primary objective of this study was to examine the validity and reliability of a semi-quantitative food frequency questionnaire(FFQ) among Chinese children aged 12-17 years. Methods A semi-quantitative 72-food item FFQ was developed for children aged 12-17 years. The reliability and validity of this FFQ were evaluated against 24-h dietary recalls(24 h DRs) to measure the consumption of foods and nutrients. We administered two FFQs and three DRs to children(N = 160) over a period of 1 month to evaluate the reliability and validity. Reliability was examined by quartile agreement and intraclass correlation coefficients(ICCs), and validity was examined by quartile agreement, Bland-Altman plots and correlation with DRs. Results For reliability, the ICCs between the two FFQs ranged from 0.21 to 0.76 for foods and nutrients, and the quartile agreement ranged from 70.0% to 95.0% in the same or adjacent quartiles. Spearman’s correlation coefficients of foods and nutrients between the second FFQ and the 24 h DRs ranged from-0.04 to 0.59. The Bland-Altman plots demonstrated good agreement across the range of intakes among nutrients. The quartile agreement ranged from 50.0% to 100.0%, with infrequent misclassification. Conclusion The FFQ assessment of dietary intakes demonstrated acceptable relative validity and high reproducibility for Chinese children aged 12-17 years.LIU Dan JU La Hong YANG Zhen Yu ZHANG Qian GAO Jian Fen GONG Di Ping GUO Dan Dan LUO Shu Quan ZHAO Wen Hua 2019Biomedical and Environmental Sciences2019,32,7:6
7Sedimentary Evolution of the Qinghai-Tibet Plateau in Cenozoic and its Response to the Uplift of the Plateau显示文摘We have studied the evolution of the tectonic lithofacies paleogeography of Paleocene-Eocene, Oligocene, Miocene, and Pliocene of the Qinghai-Tibet Plateau by compiling data regarding the type, tectonic setting, and lithostratigraphic sequence of 98 remnant basins in the plateau area. Our results can be summarized as follows. (1) The Paleocene to Eocene is characterized by uplift and erosion in the Songpan-Garzê and Gangdisê belts, depression (lakes and pluvial plains) in eastern Tarim, Qaidam, Qiangtang, and Hoh Xil, and the Neo-Tethys Sea in the western and southern Qinghai-Tibet Plateau. (2) The Oligocene is characterized by uplift in the Gangdisê-Himalaya and Karakorum regions (marked by the absence of sedimentation), fluvial transport (originating eastward and flowing westward) in the Brahmaputra region (marked by the deposition of Dazhuka conglomerate), uplift and erosion in western Kunlun and Songpan-Garzê, and depression (lakes) in the Tarim, Qaidam, Qiangtang, and Hoh Xil. The Oligocene is further characterized by depressional littoral and neritic basins in southwestern Tarim, with marine facies deposition ceasing at the end of the Oligocene. (3) For the Miocene, a widespread regional unconformity (ca. 23 Ma) in and adjacent to the plateau indicates comprehensive uplift of the plateau. This period is characterized by depressions (lakes) in the Tarim, Qaidam, Xining-Nanzhou, Qiangtang, and Hoh Xil. Lacustrine facies deposition expanded to peak in and adjacent to the plateau ca. 18-13 Ma, and north-south fault basins formed in southern Tibet ca. 13-10 Ma. All of these features indicate that the plateau uplifted to its peak and began to collapse. (4) Uplift and erosion occurred during the Pliocene in most parts of the plateau, except in the Hoh Xil-Qiangtang, Tarim, and Qaidam. The continuous uplift and intensive taphrogeny in the plateau divided the original large basin into small basins, deposition of lacustrine facies decreased considerably, and boulderstone accumulated, indicating a response to the overall uplift of the plateau. Here, we discuss the evolution of tectonic lithofacies paleogeography in Cenozoic and its response to the tectonic uplift of the Qinghai-Tibet Plateau in relation to the above characteristics. We have recognized five major uplift events, which occurred during 58-53 Ma, 45-30 Ma, 25-20 Ma, 13-7 Ma, and since 5 Ma. The results presented here indicate that the paleogeomorphic configurations of the Qinghai-Tibet Plateau turned over during the late Miocene, with high elevations in the east during the pre-Miocene switching to high contours in the west at the end of Miocene.ZHANG Kexin WANG Guocan XU Yadong LUO Mansheng JI Junliang XIAO Guoqiao WANG An SONG Bowen LIANG Yinpin JIANG Shangsong CAO Kai CHEN Fenning CHEN Ruiming YANG Yongfeng 2013Acta Geologica Sinica(English Edition)2013,87,2:6
8Post-marketing safety surveillance and reevaluation of Motherwort injection:A clinical study of 10094 cases显示文摘OBJECTIVE:To investigate the safety profiles of Motherwort injection(MI).METHODS:A multi-center,prospective and drugderived hospital intensive monitoring method was conducted to assess the safety of MI in real world applications.This study was based on a very large population after the injection was approved and marketed in China.All patients using the injection in participating hospitals were monitored to determine the incidence,pattern,severity and outcome of associated adverse events.RESULTS:The post-marketing surveillance was performed in 10 094 female patients from April to December,2015.The incidence of adverse drug reactions(ADRs) was 0.79‰(8/10 094).Among the 8 patients,the reported adverse events mainly included systemic abnormalities,such as fever,chills and eyelid edema;skin and appendages disorders,such as pruritus and rash;gastrointestinal disorders,such as nausea,abdominal distension and pain;heart rate and rhythm disorders,such as palpitation and increased heart rate.All of these ADRs were mild in severity.CONCLUSION:In this study the ADRs incidence rate of MI is very low,which supports that it is generally safe for use in obstetric and gynecological diseases.However,the total number of 8 ADRs recorded over a relatively short time span seems limited,and the low number of reports could not represent an absolute guarantee of safety.Cao Shan Zhang Wenhao Zhao Ziwei Heng Mingli Bu Huaien Wang Hongwu Liu Xinghui Wang Zhong Cai Yan Ma Yuyan Cui Shihong Deng Jihong Ding Guifeng Ding Yajuan Dong Linhong Duan Zhentao Fan Ling Fan Yang Fu Fen He Jing Ji Shuying Jin Lin Li Hong Li Hongying Liao Tao Lu Wei Luo Xiucui Lü Zhihui Ma Fengchun Ma Dafeng Shi Tianyun Sun Juying Sun Xiaotong Teng Hong Wang Jinhua Wang Ruihua Wang Ying Wang Zhengling Xi Jie Xu Minjuan Xu Zhihong Yan Qian Yang Cuirong Yang Yimei Yin Jie Yu Jinhua Yuan Wenjun Zhang Guanli Zhang Meihua Zhao Renfeng Zhong Yonghong Zhou Jian 2018Journal of Traditional Chinese Medicine2018,38,4:4
9The efficacy and safety of modified FOLFIRINOX as first-line chemotherapy for Chinese patients with metastatic pancreatic cancer显示文摘Background: Oxaliplatin, irinotecan, 5-fluorouracil, and l-leucovorin (FOLFIRINOX) has become one of the first-line treatment options for advanced pancreatic cancer (PC). However, the relatively high rate of grade 3 or 4 adverse events associated with the standard dosage of FOLFIRINOX limits its widespread use in clinical practice. In this study, we were to evaluate the efficacy and safety of a modified FOLFIRINOX regimen as a first-line chemotherapy for Chinese patients with metastatic PC. Methods: Patients with histologically confirmed primary metastatic pancreatic adenocarcinoma with an Eastern Cooperative Oncology Group (ECOG) performance status score of 0-2 were recruited to receive the modified FOLFIRINOX regimen (intravenous infusion of oxaliplatin, 65 mg/m2;irinotecan, 150 mg/m2;l-leucovorin, 200 mg/ m2;and 5-fluorouracil, 2400 mg/m2, repeated every 2 weeks). The treatment was continued for 12 cycles unless the patient had progressive disease (PD), stable disease (SD) with symptom deterioration, unacceptable adverse events, or requested to terminate the treatment prematurely. The primary endpoint was objective response rate (ORR). Results: Sixty-five patients were enrolled from July 2012 to April 2017 in three institutions, and they all received at least one cycle of chemotherapy, with a median of 8 cycles (range 1-12 cycles). No complete response was observed. Twenty-one (32.3%) patients had partial responses, and 27 (41.5%) had SD. The ORR and disease control rate of the study cohort was 32.3% and 73.8%. The estimated median overall survival and progression-free survival were 11.60 (95% confidence interval [CI] 8.76-14.44) and 5.77 (95% CI 5.00-6.54) months. Major grade 3 or 4 adverse events included neutropenia (12.3%) and diarrhea (6.2%). No treatment-related death was observed. Conclusions: Modified FOLFIRINOX was well-tolerated and might be a promising option as first-line therapy for Chinese patients with metastatic PC.Zhi-Qiang Wang Fei Zhang Ting Deng Le Zhang Fen Feng Feng-Hua Wang Wei Wang De-Shen Wang Hui-Yan Luo Rui-Hua Xu Yi Ba Yu-Hong Li 2019Cancer Communications2019,39,1:4

13Exposure to bifenthrin disrupts the development of testis in male Sebastiscus marmoratus显示文摘Bifenthrin(BF) is a pyrethroid insecticide that is widely used in agriculture, horticulture, and for residential purposes. However, few studies addressing the reproductive toxicity of BF on fishes are available. The present study was conducted to investigate the effects of BF on testicular development in Sebastiscus marmoratus and to gain insight into its mechanism. After exposure to 1, 10 and 100 ng/L BF for 50 days, there was a reduced number of mature sperm and an abundance of the late stages of spermatocysts in the testes. The levels of 17β-estradiol and testosterone were decreased significantly after BF exposure. The activity of caspase-3 was increased in a dosedependent manner after BF exposure, TUNEL assay indicated that BF exposure resulted in the occurrence of apoptosis in the testes, which might be main reason for the inhibition of spermatogenesis.LI Jinshou LUO Fen LIU Liyue RUAN Junfeng WANG Nannan 2017Acta Oceanologica Sinica2017,36,2:2
14Golden Promise barley(Hordeum vulgare) is a suitable candidate model host for investigation interaction with Heterodera avenae显示文摘Heterodera avenae(cereal cyst nematode, CCN) infects many cereal crops and causes serious yield losses worldwide. Interaction studies investigating H. avenae and its hosts are still in their infancy. In this study, a barley model plant, the Hordeum vulgare cultivar Golden Promise, was investigated for its potential as a candidate model host to study its interaction with H. avenae. CCN-infective juveniles were attracted by the root tips and gathered around the root elongation zones of Golden Promise on 0.7% water agar plates. The juveniles invaded the roots and developed successfully until maturation at 40 days after inoculation in sterile sand soil. The cryotomy and syncytium measurements indicated that the syncytia enlarged gradually throughout the development of the nematodes and caused the corresponding root regions to swell obviously. Quantitative real-time PCR analysis showed that the down-regulation of defence-related barley genes and up-regulation of development-related barley genes contribute to the understanding of compatible interaction between H. avenae and Golden Promise. Barley stripe mosaic virus(BSMV) virus-induced gene silencing(VIGS) can be used in the roots of Golden Promise. In conclusion, the Hordeum vulgare cultivar Golden Promise is a suitable candidate model host for interaction studies with Heterodera avenae. The studies presented above document the first CCN host that not only has published genome context but also be compatible to BSMV VIGS.LUO Shu-jie KONG Ling-an PENG Huan HUANG Wen-kun CUI Jiang-kuan LIU Jing QIAO Fen JIAN Heng PENG De-liang 2017Journal of Integrative Agriculture2017,16,7:2
