| 3 | Chinese herbal medicine reduces mortality in patients with severe and critical coronavirus disease 2019: a retrospective cohort study显示文摘This study aimed to evaluate the efficacy of Chinese herbal medicine(CHM)in patients with severe/critical coronavirus disease 2019(COVID-19).In this retrospective study,data were collected from 662 patients with severe/critical COVID-19 who were admitted to a designated hospital to treat patients with severe COVID-19 in Wuhan before March 20,2020.All patients were divided into an exposed group(CHM users)and a control group(non-users).After propensity score matching in a 1:1 ratio,156 CHM users were matched by propensity score to 156 non-users.No significant differences in seven baseline clinical variables were found between the two groups of patients.All-cause mortality was reported in 13 CHM users who died and 36 non-users who died.After multivariate adjustment,the mortality risk of CHM users was reduced by 82.2%(odds ratio 0.178,95%CI 0.076–0.418;P<0.001)compared with the non-users.Secondly,age(odds ratio 1.053,95%CI 1.023–1.084;P<0.001)and the proportion of severe/critical patients(odds ratio 0.063,95%CI 0.028–0.143;P<0.001)were the risk factors of mortality.These results show that the use of CHM may reduce the mortality of patients with severe/critical COVID-19. | Guohua Chen Wen Su Jiayao Yang Dan Luo Ping Xia Wen Jia Xiuyang Li Chuan Wang Suping Lang Qingbin Meng Ying Zhang Yuhe Ke An Fan Shuo Yang Yujiao Zheng Xuepeng Fan Jie Qiao Fengmei Lian Li Wei Xiaolin Tong | 2020 | Frontiers of Medicine2020，14，6： | 10 |
| 4 | Effects of extreme soil water stress on photosynthetic efficiency and water consumption characteristics of Tamarix chinensis in China's Yellow River Delta显示文摘Soil moisture is a major limiting factor for plant growth on shell ridge islands in the Yellow River Delta.However, it is difficult to carry out situ experiment to study dominant plant photosynthesis physiological on the shell ridge islands under extreme soil water stress. To evaluate the adaptability of plants to light and moisture variations under extreme soil moisture conditions present on these islands, we measured photosynthetic gas exchange process,chlorophyll fluorescence, and stem sap flow variables for3-year-old trees of Tamarix chinensis Lour, a restoration species on these islands, subjected to three types of soilwater levels: waterlogging stress(WS), alternating dry–wet(WD), and severe drought stress(SS) to inform decisions on its planting and management on shell ridge islands. Gas exchange, chlorophyll fluorescence, and stem sap flow in T.chinensis were then measured. Net photosynthetic rate(PN), transpiration rate(E), and water use efficiency(WUE)were similar under WS and alternating dry–wet conditions,but their mean E and WUEdiffered significantly(P \ 0.05).Under SS, the PN, E and WUEof T. chinensis leaves varied slightly, and mean PN, E and WUEwere all low. Apparent quantum efficiency(AQY), light compensation point(LCP),light saturation point(LSP), and maximum net photosynthetic rate(PNmax) of leaves were not significantly different(P [ 0.05) under WS and dry–wet conditions; however,under extreme drought stress, compared with the dry–wet conditions, LCPwas higher, LSPwas lower, and AQYand PNmaxwere both at the lowest level. Therefore, drought stress weakened light adaptability of leaves, and the efficiency of light transformation was poorer.(3) Maximum photochemical efficiency(Fv/Fm) and the actual photochemical efficiency(UPSII) were similar under waterlogged stress and dry–wet conditions, indicating a similar healthy photosynthetic apparatus and photosynthetic reaction center activity, respectively. Under SS, Fv/Fmwas 0.631, and the coefficient of non-photochemical quenching(NPQ) was0.814, which indicated that while the photosynthetic mechanism was damaged, the absorbed light energy was mainly dissipated in the form of heat, and the potential photosynthetic productivity was significantly reduced. The daily cumulants of sap flow of T. chinensis under dry–wet alternation and severe drought stress were 22.25 and63.97% higher, respectively, than under waterlogging stress. Daily changes in sap flow velocity for T. chinensis differed under the three soil water levels. Stem sap flow was weak at night under severe drought stress. Under dry–wet alternation, daytime average stem sap flow velocity was the highest, and night stem flow accounted for 10.26%of the day cumulants, while under waterlogged stress, the average nightly stem flow velocity was the highest,accounting for 31.82% of the day cumulants. These results provide important information for regional vegetation restoration and ecological reconstruction. | Yuan Gao Jiangbao Xia Yinping Chen Yanyun Zhao Qingxian Kong Ying Lang | 2017 | Journal of Forestry Research2017，28，3： | 9 |
| 5 | Effects of soil drought stress on photosynthetic gas exchange traits and chlorophyll fluorescence in Forsythia suspensa显示文摘To clarify the changes in plant photosynthesis and mechanisms underlying those responses to gradually increasing soil drought stress and reveal quantitative relationships between photosynthesis and soil moisture,soil water conditions were controlled in greenhouse pot experiments using 2-year-old seedlings of Forsythia suspensa(Thunb.) Vahl. Photosynthetic gas exchange and chlorophyll fluorescence variables were measured and analyzed under 13 gradients of soil water content. Net photosynthetic rate(PN), stomatal conductance(gs), and water-use efficiency(WUE) in the seedlings exhibited a clear threshold response to the relative soil water content(RSWC). The highest PNand WUEoccurred at RSWCof51.84 and 64.10%, respectively. Both PNand WUEwere higher than the average levels at 39.79% B RSWCB 73.04%. When RSWCdecreased from 51.84 to 37.52%,PN, gs, and the intercellular CO2 concentration(Ci)markedly decreased with increasing drought stress; the corresponding stomatal limitation(Ls) substantially increased, and nonphotochemical quenching(NPQ) also tended to increase, indicating that within this range of soil water content, excessive excitation energy was dispersed from photosystem II(PSII) in the form of heat, and the reduction in PNwas primarily due to stomatal limitation.While RSWCdecreased below 37.52%, there were significant decreases in the maximal quantum yield of PSII photochemistry(Fv/Fm) and the effective quantum yield of PSII photochemistry(UPSII), photochemical quenching(qP), and NPQ; in contrast, minimal fluorescence yield of the dark-adapted state(F0) increased markedly. Thus,the major limiting factor for the PNreduction changed to a nonstomatal limitation due to PSII damage. Therefore, an RSWCof 37.52% is the maximum allowable water deficit for the normal growth of seedlings of F. suspensa, and a water content lower than this level should be avoided in field soil water management. Water contents should be maintained in the range of 39.79% B RSWCB 73.04% to ensure normal function of the photosynthetic apparatus and high levels of photosynthesis and efficiency in F.suspensa. | Ying Lang Ming Wang Jiangbao Xia Qiankun Zhao | 2018 | Journal of Forestry Research2018，29，1： | 9 |
| 6 | Correlation between Helicobacter pylori-associated gastric diseases and colorectal neoplasia显示文摘AIM: To explore the correlation between Helicobacter pylori(H. pylori)-associated gastric diseases and colorectal neoplasia.METHODS: Patients included in this study underwent a colonoscopy and esophago-gastro-duodenoscopy(EGD) along with histopathological measurement between March 2012 and March 2015 at Qi-Lu Hospital of Shandong University, who also had results of H. pylori detection. A total of 233 cases were selected. Demographic data, H. pylori infection status(including results of rapid urease tests and gastric mucosa pathological examinations) and histopathological examination results of gastric and colorectal mucosa were gathered and analyzed. The statistical analysis focused on the prevalence of colorectal neoplasms among patients with various histopathological categories of the stomach. ORs and their 95%CI were calculated to describe the strengths of the associations.RESULTS: The incidence rates of colorectal adenoma without high-grade intraepithelial neoplasia(HGIEN)(OR = 2.400, 95%CI: 0.969-5.941), adenoma with HGIEN(5.333, 1.025-27.758) and adenocarcinoma(1.455, 0.382-5.543) were all higher for patients with H. pylori-associated gastritis than for those in the control group. The incidence rate of colorectal adenoma with HGIEN(3.218, 0.767-13.509) was higher in patients with intestinal metaplasia than in the control group, while the incidence rates of adenoma without HGIEN(0.874, 0.414-1.845) and adenocarcinoma(0.376, 0.096-1.470) were lower in the intestinal metaplasia group than in the control group. The incidence rate of colorectal adenoma without HGIEN(3.111, 1.248-7.753) was significantly higher in the gastric intraepithelial neoplasia group than in the control group, while the rates of adenoma with HGIEN(1.481, 0.138-15.941) and adenocarcinoma(2.020, 0.561-7.272) were higher in the gastric intraepithelial neoplasia group. Incidence rates of colorectal adenoma without HGIEN(1.067, 0.264-4.314), adenoma with HGIEN(2.667, 0.231-30.800) and adenocarcinoma(2.182, 0.450-10.585) were all higher in the gastric adenocarcinoma group than in the control group.CONCLUSION: H. pylori infection as well as H. pylori-associated gastric diseases are risk factors for colorectal neoplasia. | Ying Qing Min Wang Ying-Min Lin Dong Wu Jing-Yu Zhu Lang Gao Yan-Yan Liu Teng-Fei Yin | 2016 | World Journal of Gastroenterology2016，22，18： | 8 |

| 15 | SEVEN CASES OF EPITHELIAL OVARIAN CARCINOMA WITH BRAIN METASTASIS显示文摘Objective To summarize the clinical characteristics,treatment,and prognosis of brain metastasis in patients with epithelial ovarian carcinoma.Methods Retrospective analysis was conducted in 7 cases of brain metastases of epithelial ovarian carcinoma from January 1986 to March 2007 in Peking Union Medical College Hospital for summarizing therapy results and prognosis-affecting factors.Results Incidence of brain metastases of epithelial ovarian carcinoma was about 0.66%(7/1055).Serous adenocarcinoma was the predominant pathological type in 4 cases and the subsequent was adenocarcinoma in 3 cases.All the patients were diagnosed at late stage,6 cases with the International Federation of Gynecology and Obstetrics(FIGO)stage IIIc and 1 with FIGO stage IV.The mean duration from diagnosis of ovarian carcinoma to brain metastasis was 32.7±20.0 months(range,23-73 months).Single metastasis focus occurred in 43% of cases and multiple metastases in 57% of cases.Fifty-seven percent of patients presented extracranial metastasis.Serum CA125 played a role in monitoring reoccurrence and brain metastases.The average survival time was about 12 months.Better treatment with prolonged survival could be achieved by combination of operation and chemotherapy or combination of radiotherapy with chemotherapy.Conclusions As a rare condition,brain metastasis of epithelial ovarian carcinoma is rising in incidence with improved treatment of ovarian carcinoma and prolonged survival.However,brain metastasis indicates bad prognosis which can be improved by combined therapy. | Jia-xin Yang Keng Shen Ying Shan Li-na Guo Hui-fang Huang Jing-he Lang Ming Wu Ling-ya Pan | 2008 | Chinese Medical Sciences Journal2008，23，1： | 2 |
| 16 | A Neural Network Method for Monitoring Snowstorm: A Case Study in Southern China显示文摘It has been observed that low temperature, rainfall, snowfall, frost have never occurred over the past 50 years in the southern China, and weather in this area is very complex, so the monitoring equipments are few. Optical and thermal infrared remote sensing is influenced much by clouds, so the passive microwave Advanced Microwave Scanning Radiometer-Earth Observing System(AMSR-E) data are the best choice to monitor and analyze the development of disaster. In order to improve estimation accuracy, the dynamic learning neural network was used to retrieve snow depth. The difference of brightness temperatures of TB18.7V and TB36.5V, TB18.7H and TB36.5H, TB23.8V and TB89 V, TB23.8H and TB89 H are made as four main input nodes and the snow depth is the only one output node of neural network. The mean and the standard deviation of retrieval errors are about 4.8 cm and 6.7 cm relative to the test data of ground measurements. The application analysis indicated that the neural network can be utilized to monitor the change of snow intensity distribution through passive microwave data in the complex weather of the southern China. | MAO Kebiao MA Ying XIA Lang SHEN Xinyi SUN Zhiwen HE Tianjue ZHOU Guanhua | 2014 | Chinese Geographical Science2014，24，5： | 2 |
| 17 | Effects of Blast Wave-induced Biomechanical Changes on Lung Injury in Rats显示文摘Objective To observe the dynamic impacts of shock waves on the severity of lung injury in rats with different injury distances.Methods Simulate open-field shock waves;detect the biomechanical effects of explosion sources at distances of 40,44,and 48 cm from rats;and examine the changes in the gross anatomy of the lungs,lung wet/dry weight ratio,hemoglobin concentration,blood gas analysis,and pathology.Results Biomechanical parameters such as the overpressure peak and impulse were gradually attenuated with an increase in the injury distance.The lung tissue hemorrhage,edema,oxygenation index,and pathology changed more significantly for the 40 cm group than for the 44 and 48 cm groups.The overpressure peak and impulse were significantly higher for the 40 cm group than for the 44 and 48 cm groups(P<0.05 or P<0.01).The animal mortality was significantly higher for the 40 cm group than for the other two groups(41.2%vs.17.8%and 10.0%,P<0.05).The healing time of injured lung tissues for the 40 cm group was longer than those for the 44 and 48 cm groups.Conclusions The effects of simulated open-field shock waves on the severity of lung injuries in rats were correlated with the injury distances,the peak overpressure,and the overpressure impulse. | LIU Wei CHAI Jia Ke QIN Bin HAN Shao Fang WANG Xiao Teng JIANG Shuai BAI Hai Liang LIU Ling Ying CHANG Yang YUE Xiao Tong WU Yu Shou ZHANG Zi Hao TANG Lang | 2020 | Biomedical and Environmental Sciences2020，33，5： | 2 |
| 18 | Evaluation of triage strategies for high-risk human papillomavirus-positive women in cervical cancer screening:A multicenter randomized controlled trial in different resource settings in China显示文摘Objective:We aimed to evaluate the effectiveness of different triage strategies for high-risk human papillomavirus(hrHPV)-positive women in primary healthcare settings in China.Methods:This study was undertaken in 11 rural and 9 urban sites.Women aged 35-64 years old were enrolled.HrHPV-positive women were randomly allocated to liquid-based cytology(LBC),visual inspection with acetic acid and Lugol’s iodine(VIA/VILI)(rural only)triage,or directly referred to colposcopy(direct COLP).At 24 months,hrHPV testing,LBC and VIA/VILI were conducted for combined screening.Results:In rural sites,1,949 hrHPV-positive women were analyzed.A total of 852,218 and 480 women were randomly assigned to direct COLP,LBC and VIA/VILI.At baseline,colposcopy referral rates of LBC or VIA/VILI triage could be reduced by 70%-80%.LBC(n=3 and n=7)or VIA/VILI(n=8 and n=26)could significantly decrease the number of colposcopies needed to detect one cervical intraepithelial neoplasia(CIN)2 or worse and CIN3+compared with direct COLP(n=14 and n=23).For the 24-month cumulative detection rate of CIN2+,VIA/VILI triage was 0.50-fold compared with LBC triage and 0.46-fold with the direct COLP.When stratified by age,baseline LBC triage+performed best(P<0.001),peaking among women aged 35-44 years(Ptrend=0.002).In urban sites,1,728 women were hrHPV genotyping test positive.A total of 408,571 and 568women were randomly assigned to direct COLP for HPV16/18+,direct COLP for other hrHPV subtypes+,and LBC triage for other hrHPV subtypes+.LBC(n=12 and n=31)significantly decreased the number of colposcopies needed to detect one CIN2+and CIN3+compared with direct COLP(n=14 and n=44).HPV16/18+increased the 24-month cumulative detection rate of CIN2+(17.89%,P<0.001).Conclusions:LBC triage for hrHPV-positive women in rural settings and direct COLP for HPV16/18+women and LBC triage for other hrHPV subtype+women in urban settings might be feasible strategies. | Le Dang Linghua Kong Yuqian Zhao Yi Dai Li Ma Lihui Wei Shulan Zhang Jihong Liu Mingrong Xi Long Chen Xianzhi Duan Qing Xiao Guzhalinuer Abulizi Guonan Zhang Ying Hong Qi Zhou Xing Xie Li Li Mayinuer Niyazi Zhifen Zhang Jiyu Tuo Yiling Ding Youlin Qiao Jinghe Lang | 2022 | Chinese Journal of Cancer Research2022，34，5： | 2 |

SETTING: Beijing Tiantan Hospital, Beijing Anzhen Hospital, General Hospital of Beijing Military Area, Command of Chinese PLA, Beijing Chuiyangliu Hospital, Beijing 6th Hospital, Beijing Hepingli Hospital, and Beijing Daxing District Hospital. PARTICIPANTS: A total of 28 (associate) chief physicians, 58 attending physicians, and 54 resident physicians who engaged in clinical treatment of cerebrovascular diseases were selected from 8 hospitals in Beijing from March to April 2007. All physicians provided informed consent. METHODS: Self-made closed questionnaires were provided for data collection, consisting of 16 questions that were single choice or multiple choice. Specifically, questions 1-7 focused on awareness of blood pressure regulation in different patients and first choice of decompression drug; questions 8-12 focused on awareness of lipid regulation; and questions 13-16 focused on awareness of anti-blood platelet drugs applied in secondary prevention. The scores ranged from 0-100 points, and each question was worth 6.25 points. The scores positively correlated with the awareness rate. To test leveling real-time, the survey lasted for a maximum of 20 minutes. One questionnaire was independently finished by each subject in the survey. MAIN OUTCOME MEASURES: Awareness intervention among neurologists during secondary prevention of cerebral infarction/transient ischemia and questionnaire scores. RESULTS: 140 subjects were included in the final analysis. ① The awareness rate among neurologists for intervention during secondary prevention of cerebral infarction/transient ischemia ranged from 0.7-57.9%, the scores ranged between 0-56 points, and the mean score was 26 points. ② Scores of resident physicians were 0-56 points with a mean score of 26 points; attending physicians scored 6-50 points, with a mean score of 26 points; and chief physicians scored 6-50 points, with a mean score of 23 points. There were no significant differences among the various physicians (F = 0.771, t = 0.465, P > 0.05). CONCLUSION: Awareness among neurologists of intervention during secondary prevention of cerebral infarction/transient ischemia is not ideal. However, there was no significant difference between professional titles. | Ruihua Ma Chunxue Wang Xianwei Wang Yuhui Zhang Yongjun Wang Yilong Wang Xingquan Zhao Jingjing Li Ying Lu Mingjie Xu Zhuo Zhang Li Wang Weiwei Zhang Lang Lin Jiping Tan Yao Li Ming Wei Hongtao Li | 2008 | Neural Regeneration Research2008，3，3： | 2 |
