2Expenditure and financial burden for the diagnosis and treatment of colorectal cancer in China:a hospital.based,multicenter,cross-sectional survey显示文摘Background: The increasing prevalence of colorectal cancer(CRC) in China and the paucity of information about relevant expenditure highlight the necessity of better understanding the financial burden and effect of CRC diagnosis and treatment. We performed a survey to quantify the direct medical and non-medical expenditure as well as the resulting financial burden of CRC patients in China.Methods: We conducted a multicenter, cross-sectional survey in 37 tertiary hospitals in 13 provinces across China between 2012 and 2014. Each enrolled patient was interviewed using a structured questionnaire. All expenditure data were inflated to the 2014 Chinese Yuan(CNY; 1 CNY = 0.163 USD). We quantified the overall expenditure and financial burden and by subgroup(hospital type, age at diagnosis, sex, education, occupation, insurance type, household income, clinical stage, pathologic type, and therapeutic regimen). We then performed generalized linear modeling to determine the factors associated with overall expenditure.Results: A total of 2356 patients with a mean age of 57.4 years were included, 57.1 % of whom were men; 13.9% of patients had stage I cancer; and the average previous-year household income was 54,525 CNY.The overall average direct expenditure per patient was estimated to be 67,408 CNY, and the expenditures for stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ disease were 56,099 CNY, 59,952 CNY, 67,292 CNY, and 82,729 CNY, respectively. Non-medical expenditure accounted for 8.3%of the overall expenditure. The 1-year out-of-pocket expenditure of a newly diagnosed patient was 32,649 CNY, which accounted for 59.9% of their previous-year household income and caused 75.0% of families to suffer an unmanageable financial burden. Univariate analysis showed that financial burden and overall expenditure differed in almost all subgroups(P < 0.05), except for sex. Multivariate analysis showed that patients who were treated in specialized hospitals and those who were diagnosed with adenocarcinoma or diagnosed at a later stage were likely to spend more,whereas those with a lower household income and those who underwent surgery spent less(all P < 0.05).Conclusions: For patients in China, direct expenditure for the diagnosis and treatment of CRC seemed catastrophic,and non-medical expenditure was non-ignorable. The financial burden varied among subgroups, especially among patients with different clinical stages of disease, which suggests that, in China, CRC screening might be cost-effective.Hui-Yao Huang Ju-Fang Shi Lan-Wei Guo Ya-Na Bai Xian-Zhen Liao Guo-iangLiu A-Yan Mao Jian-Song Ren Xiao-Jie Sun Xin-Yu Zhu Le Wang Bing-Bing Song Ling-Bin Du Lin Zhu Ji-Yong Gong Qi Zhou Yu-Qin Liu Rong Cao Ling Mai Li Lan Xiao-Hua Sun Ying Ren Jin-Yi Zhou Yuan-Zheng Wang Xiao Qi Pei-An Lou Dian Shi Ni Li Kai Zhang Jie He Min Dai 2017Chinese Journal of Cancer2017,36,8:25
3SHRIMP U-Pb zircon dating for lamprophyre from Liaodong Peninsula: Constraints on the initial time of Mesozoic lithosphere thinning beneath eastern China显示文摘It is undebated fact that the lithospheric mantle beneath eastern China was considerably thinned during the Mesozoic time. However, it has no adequate evidence for the exact timing when the lithosphere thinning started. The Liaodong Peninsula is located in the eastern segment of the North China Craton and is one of the important domains to explore the event of lithosphere thinning. SHRIMP U-Pb zircon dating and geochemical study were carried out for the lamprophyre dike swarm that intruded into the magnesite ore-beds in the Dashiqiao Formation of Paleoproterozoic Liaohe Group at the Huaziyu magnesite ore district, Liaodong Peninsula. The results indicate that these lampro- phyre dikes were intruded in late Jurassic (155±4 Ma) and show some geochemical characteristics of potassic magmas. It is now accepted that the lithosphere thinning took place in the late Mesozoic, and the peak thinning stage occurred in early Cretaceous (130―120 Ma). Considering the potassic mafic magmatism marking the onset of the lithospheric thin- ning, we therefore suggest that the studied late Jurassic potassic lamprophyre dike swarm could imply that the late Jurassic is the time that lithosphere thinning started.JIANG Yaohui JIANG Shaoyong ZHAO Kuidong NI Pei LING Hongfei LIU Dunyi 2005Chinese Science Bulletin2005,50,22:22

6Combination of western medicine and Chinese traditional patent medicine in treating a family case of COVID-19显示文摘In December 2019,an outbreak of novel coronavirus(2019-nCoV)occurred in Wuhan,Hubei Province,China.By February 14,2020,it has led to 66492 confirmed patients in China and high mortality up to^2.96%(1123/37914)in Wuhan.Here we report the first family case of coronavirus disease 2019(COVID-19)confirmed in Wuhan and treated using the combination of western medicine and Chinese traditional patent medicine Shuanghuanglian oral liquid(SHL).This report describes the identification,diagnosis,clinical course,and management of three cases from a family,suggests the expected therapeutic effects of SHL on COVID-19,and warrants further clinical trials.Li Ni Ling Zhou Min Zhou Jianping Zhao Dao Wen Wang 2020Frontiers of Medicine2020,14,2:15
7Ciliary parathyroid hormone signaling activates transforming growth factor-βto maintain intervertebral disc homeostasis during aging显示文摘Degenerative disc disease(DDD) is associated with intervertebral disc degeneration of spinal instability. Here, we report that the cilia of nucleus pulposus(NP) cells mediate mechanotransduction to maintain anabolic activity in the discs. We found that mechanical stress promotes transport of parathyroid hormone 1 receptor(PTH1 R) to the cilia and enhances parathyroid hormone(PTH) signaling in NP cells. PTH induces transcription of integrin α_vβ_6 to activate the transforming growth factor(TGF)-β-connective tissue growth factor(CCN2)-matrix proteins signaling cascade. Intermittent injection of PTH(iPTH) effectively attenuates disc degeneration of aged mice by direct signaling through NP cells, specifically improving intervertebral disc height and volume by increasing levels of TGF-β activity, CCN2, and aggrecan. PTH1 R is expressed in both mouse and human NP cells. Importantly,knockout PTH1 R or cilia in the NP cells results in significant disc degeneration and blunts the effect of PTH on attenuation of aged discs. Thus, mechanical stress-induced transport of PTH1 R to the cilia enhances PTH signaling, which helps maintain intervertebral disc homeostasis, particularly during aging, indicating therapeutic potential of iPTH for DDD.Liwei Zheng Yong Cao Shuangfei Ni Huabin Qi Zemin Ling Xin Xu Xuenong Zou Tianding Wu Ruoxian Deng Bo Hu Bo Gao Hao Chen Yusheng Li Jianxi Zhu Francis Tintani Shadpour Demehri Amit Jain Khaled M.Kebaish Shenghui Liao Cheryle A.Séguin Janet L.Crane Mei Wan Hongbin Lu Paul D.Sponseller Lee H.RileyIII Xuedong Zhou Jianzhong Hu Xu Cao 2018Bone Research2018,6,3:13

11Land Use/Cover Changes and Environmental Consequences in Songnen Plain,Northeast China显示文摘The Songnen Plain in Northeast China,one of the key national bases of agricultural production,went through remarkable land use/cover changes in recent years.This study aimed to explore the long-term land use/cover changes and the effects of these changes on the environment.The Landsat-based analysis showed that,during 1986-2000,cropland,built-up land and barren land had increased,among which cropland had the largest increase of 9,198km2 with an increase rate of 7.5%.Woodland,grassland,water body and swampland had decreased correspondingly,among which grassland had the most dramatic decrease of 6,127km2 with a decrease rate of 25.6%.The transition matrix results revealed that grassland,woodland and swampland were the three main land use types converted to cropland.Climate warming created the potential environment for the conversion of grassland and swampland into cropland.Land resources policy made by central and provincial governments of China affected the pattern and intensity of land use.Land use/cover changes accompanied by climatic variation brought out a series of environmental consequences,such as sand desertification of land,land salinization and alkalinization,grassland degradation,and more frequent floods.Under this circumstance,optimized land use structure and restoration measures are needed.LIU Dianwei WANG Zongming SONG Kaishan ZHANG Bai HU Liangjun HUANG Ni ZHANG Sumei LUO Ling ZHANG Chunhua JIANG Guangjia 2009Chinese Geographical Science2009,19,4:8
12Tumor-expressed B7-H3 mediates the inhibition of antitumor T-cell functions in ovarian cancer insensitive to PD-1 blockade therapy显示文摘Although PD-L1/PD-1 blockade therapy has been approved to treat many types of cancers,the majority of patients with solid tumors do not respond well,but the underlying reason remains unclear.Here,we studied ovarian cancer(OvCa),a tumor type generally resistant to current immunotherapies,to investigate PD-1-independent immunosuppression.We found that PD-L1 was not highly expressed in the tumor microenvironment(TME)of human OvCa.Instead,B7-H3,another checkpoint molecule,was highly expressed by both tumor cells and tumor-infiltrating antigen-presenting cells(APCs),which correlated with T-cell exhaustion in patients.Using ID8 OvCa mouse models,we found that B7-H3 expressed on tumor cells,but not host cells,had a dominant role in suppressing antitumor immunity.Therapeutically,B7-H3 blockade,but not PD-1 blockade,prolonged the survival of ID8 tumorbearing mice.Collectively,our results demonstrate that tumor-expressed B7-H3 inhibits the function of CD8^(+)T cells and suggest that B7-H3 may be a target in patients who are not responsive to PD-L1/PD-1 inhibition,particularly OvCa patients.Dongli Cai Jiaming Li Dingfeng Liu Shanjuan Hong Qin Qiao Qinli Sun Pingping Li Nanan Lyu Tiantian Sun Shan Xie Li Guo Ling Ni Liping Jin Chen Dong 2020Cellular & Molecular Immunology2020,17,3:8
13No expenditure difference among patients with liver cancer at stageⅠ-ⅣV:Findings from a multicenter cross-sectional study in China显示文摘Objective:The number of liver cancer patients in China accounts for more than half of the world.However,China currently lacks national,multicenter economic burden data,and meanwhile,measuring the differences among different subgroups will be informative to formulate corresponding policies in liver cancer control.Thus,the aim of the study was to measure the economic burden of liver cancer by various subgroups.Methods:A hospital-based,multicenter and cross-sectional survey was conducted during 2012・2014,covering 39 hospitals and 21 project sites in 13 provinces across China.The questionnaire covers clinical information,sociology,expenditure,and related variables.All expenditure data were reported in Chinese Yuan(CNY)using 2014 values.Results:A total of 2,223 liver cancer patients were enrolled,of whom 59.61%were late-stage cases(III-IV),and 53.8%were hepatocellular carcinoma.The average total expenditure per liver cancer patient was estimated as 53,220 CNY,including 48,612 CNY of medical expenditures(91.3%)and 4,608 CNY of non-medical expenditures(8.7%).The average total expenditures in stage I,H,m and stage IV were 52,817 CNY,50,877 CNY,50,678 CNY and 54,089 CNY(P>0.05),respectively.Non-medical expenditures including additional meals,additional nutrition care,transportation,accommodation and hired informal nursing were 1,453 CNY,839 CNY,946 CNY,679 CNY and 200 CNY,respectively.The one-year out-of-pocket expenditure of a newly diagnosed patient was 24,953 CNY,and 77.2%of the patients suffered an unmanageable financial burden.Multivariate analysis showed that overall expenditure differed in almost all subgroups(P<0.05),except for sex,clinical stage,and pathologic type.Conclusions:There was no difference in treatment expenditure for liver cancer patients at different clinical stages,which suggests that maintaining efforts on treatment efficacy improvement is important but not enough.To fiirtherly reduce the overall economic burden from liver cancer,more effort should be given to primary and secondary prevention strategies.Haike Lei Lin Lei Jufang Shi Yongzhong Wu Ling Liang Huiyao Huang Mei He Fangzhou Bai Maomao Cao Hui Qiu Yuting Wang Chengcheng Liu Jia Du Hong Wang Yan Zhang Mengdi Cao Ji Peng Ni Li Chunfeng Qu Min Dai Wanqing Chen Jie He 2020Chinese Journal of Cancer Research2020,32,4:7
14Effects of Shuanghuanglian oral liquids on patients with COVID-19:a randomized,open-label,parallel-controlled,multicenter clinical trial显示文摘We conducted a randomized,open-label,parallel-controlled,multicenter trial on the use of Shuanghuanglian(SHL),a traditional Chinese patent medicine,in treating cases of COVID-19.A total of 176 patients received SHL by three doses(56 in low dose,61 in middle dose,and 59 in high dose)in addition to standard care.The control group was composed of 59 patients who received standard therapy alone.Treatment with SHL was not associated with a difference from standard care in the time to disease recovery.Patients with 14-day SHL treatment had significantly higher rate in negative conversion of SARS-CoV-2 in nucleic acid swab tests than the patients from the control group(93.4%vs.73.9%,P=0.006).Analysis of chest computed tomography images showed that treatment with high-dose SHL significantly promoted absorption of inflammatory focus of pneumonia,which was evaluated by density reduction of inflammatory focus from baseline,at day 7(mean difference(95%CI),−46.39(−86.83 to−5.94)HU;P=0.025)and day 14(mean difference(95%CI),−74.21(−133.35 to−15.08)HU;P=0.014).No serious adverse events occurred in the SHL groups.This study illustrated that SHL in combination with standard care was safe and partially effective for the treatment of COVID-19.Li Ni Zheng Wen Xiaowen Hu Wei Tang Haisheng Wang Ling Zhou Lujin Wu Hong Wang Chang Xu Xizhen Xu Zhichao Xiao Zongzhe Li Chene Li Yujian Liu Jialin Duan Chen Chen Dan Li Runhua Zhang Jinliang Li Yongxiang Yi Wei Huang Yanyan Chen Jianping Zhao Jianping Zuo Jianping Weng Hualiang Jiang Dao Wen Wang 2021Frontiers of Medicine2021,15,5:7

17Intra-abdominal pressure monitoring in predicting outcome of patients with severe acute pancreatitis显示文摘BACKGROUND:Severe acute pancreatitis(SAP) is a serious disease with many complications,high mortality and poor prognosis. It is characterized by rapid deterioration and poses one of the most difficult challenges in clinical practice. Previous investigations suggest that SAP is one of the main causes of intra-abdominal pressure(IAP) increase. The aim of this study was to evaluate the utility of IAP-monitoring in predicting the severity and prognosis of SAP. METHODS:Eighty-nine patients with SAP who had been treated from February 2001 to December 2005 were studied. Since bladder pressure accurately reflects IAP,we measured it instead of IAP. Bladder pressure was measured at the time of admission and every 12 hours in the course of the disease,9 consecutive times in all. The APACHE Ⅱ scores of all patients were obtained within 24 hours after admission. According to a maximum bladder pressure <10 cmH2O,all patients were divided into two groups,mildly-elevated and severely-elevated. Mortality and mean APACHE Ⅱ scores in the two groups were calculated. In addition,the mean bladder pressure and APACHE Ⅱ scores in survivors were compared with those in deaths. RESULTS:Sixty-eight of the 89 patients were in the severely-elevated group. Mortality and mean APACHE Ⅱ scores in this group were much higher than those in the mildly-elevated group(mortality,39.71% vs. 9.52%;mean APACHE Ⅱ score,23.15±7.42 vs. 15.95±5.35,P<0.01). The mean bladder pressures and APACHE Ⅱ scores in deaths were significantly greater than those in survivors(mean bladder pressure,14.1±3.8 vs. 9.2±2.3 cmH2O,P<0.01;mean APACHE Ⅱ score,27.83±4.87 vs. 18.37±6.74,P<0.01). CONCLUSION:It is suggested that IAP may be used as a marker of the severity and prognosis of SAP.Zhang, Wei-Fang Ni, Yun-Lan Cai, Ling Li, Tong Fang, Xue-Ling Zhang, Yun-Tao 2007Hepatobiliary & Pancreatic Diseases International2007,6,4:6

19Apoptosis of pancreatic cancer BXPC-3 cells induced by indole-3-acetic acid in combination with horseradish peroxidase显示文摘AIM: To explore the mechanisms underlying the apoptosis of human pancreatic cancer BXPC-3 cells induced by indole-3-acetic acid (TAA) in combination with horseradish peroxidase (HRP).METHODS: BXPC-3 cells derived from human pancreatic cancer were exposed to 40 or 80 μmol/L IAA and 1.2 μg/mL HRP at different times. Then, MTT assay was used to detect the cell proliferation. Flow cytometry was performed to analyze cell cycle. Terminal deoxynucleotidyl transferasemediated dUTP nick end labeling assay was used to detect apoptosis. 2,7-Dichlorofluorescin diacetate uptake was measured by confocal microscopy to determine free radicals. Level of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) were measured by biochemical methods.RESULTS: IAA/HRP initiated growth inhibition of BXPC-3 cells in a dose- and time-dependent manner. Flow cytometry revealed that the cells treated for 48 h were arrested at G1/G0. After exposure to 80 μmol/L IAA plus 1.2 μg/mL HRP for 72 h, the apoptosis rate increased to 72.5‰,which was nine times that of control. Content of MDA and activity of SOD increased respectively after treatment compared to control. Meanwhile, IAA/HRP stimulated the formation of free radicals.CONCLUSION: The combination of IAA and HRP can inhibit the growth of human pancreatic cancer BXPC-3 cells in vitro by inducing apoptosis.Chen Huang Li-Ying Liu Tu-Sheng Song Lei Ni Ling Yang Xiao-Yan Hu Jing-Song Hu Li-Ping Song Yu Luo Lu-Sheng Si 2005World Journal of Gastroenterology2005,11,29:5
20Reduced function and disassembled microtubules of cultured cardiomyocytes in spaceflight显示文摘Lack of gravity during spaceflight has profound effects on cardiovascular system, but little is known about how the cardiomyocytes respond to microgravity. In the present study, the effects of spaceflight on the structure and function of cultured cardiomyocytes were reported. The primary cultures of neo- natal rat cardiomyocytes were carried on Shenzhou-6 spacecraft and activated at 4 h in orbit. 8 samples were fixed respectively at 4, 48 and 96 h after launching for immunofluorescence of cytoskeleton, and 2 samples remained unfixed to analyze contractile and secretory functions of the cultures. Ground sam- ples were treated in our laboratory in parallel. After 115 h spaceflight, video recordings displayed that the number of spontaneous beating sites in flown samples decreased significantly, and the cells in the beating aggregate contracted in fast frequency without synchrony. Radioimmunoassay of the medium showed that the atrial natriuretic peptide secreted from flown cells reduced by 59.6%. Confocal images demonstrated the time-dependant disassembly of mirotubules versus unchanged distribution and or- ganization of microfilaments. In conclusion, above results indicate reduced function and disorganized cytoskeleton of cardiomyocytes in spaceflight, which might provide some cellular basis for further investigations to probe into the mechanisms underlying space cardiovascular dysfunction.YANG Fen LI YingHui DING Bai NIE JieLin WANG HongHui ZHANG XiaoYou WANG ChunYan LING ShuKuan NI ChengZhi DAI ZhongQuan TAN YingJun WAN YuMin 2008Chinese Science Bulletin2008,53,8:5
