3Dynamic expression of apoptosis-related genes during development of laboratory hepatocellular carcinoma and its relation to apoptosis显示文摘AIM:To explore the expression of p53,bcl-2,bax,survivin and the cell apoptosis during the development of tree shrew hepatocellular carcinoma(HCC),the relationship between expression of these genes,its impact on HCC development,and its relation to cell apoptosis.METHONS:Tree shrew HCC was induced with aflatoxin B1(AFB1),and regular biopsy of liver tissues was carried out and the biopsy tissues were collected during cancer inducement.Liver biopsy tisue and HCC tissue were collected from 35pre-cancerous experimental animats at wk 30 and 60 and at the 30th_,60th_,and 90th-wk,Liver biopsy tissues were collected from 13 blank control animals at wk 30,60,and 90.Expression of p53,bcl-2,bax,and survivin at each stage was examined by immunohistochemistry method.Apoptotic cells were detected in situ by the terminal deoxynucleotidyl transferase-mediated nick end labeling(tunel)technique.RESULTS:The apoptosis rate of normal hepatic cells was extremely low,whereas it increased during the formation of HCC.Expression of the apoptosis-related genes p53,bd-2,bax,and suvivin during the formation of HCC presented an increasing tendency.Expression of p53 did not noticeably relate to that of bcl-2,bax,and survivin,whereas expression of bcl-2 and bax was closely related.In HCC,p53 did not present a distinct relation to cell apoptosis,whereas its high level expression was probably related to liver cell proliferation.Survivin negetively correlated apoptosis index,and its overexpression could inhibit cell apoptosis.CONCLUSION:Apoptosis-related genes p53,bcl-2,bax,and survivin are all related to the occurrence of HCC.The anti-apoptosis effect of bcl-2 is influenced by bax,and ratio bcl/bax reflects more correctly the extent of cell apoptosis.Xiao-Xian Duan Jing-Sheng Ou Yuan Li Jian-Jia Su Chao Ou Chun Yang Hui-Fen Yue Ke-Chen Ban 2005World Journal of Gastroenterology2005,11,30:38
4Alteration of p53 and p21 during hepatocarcinogenesis in tree shrews显示文摘AIM: To investigate p53 mutation and p21 expression in hepatocarcinogenesis induced by hepatitis B virus (HBV) and aflatoxin B1 (AFB1) in tree shrews, and to reveal the role of these genes in hepatocarcinogenesis.METHODS: Tree shrews were divided into four groups:group A, those infected with HBV and fed with AFB1 (n = 39);group B, those infected with HBV alone (n = 28); group C,those fed with AFB1 alone (n = 29); and group D, normal controls (n = 20). The tree shrews underwent liver biopsies once every 15 wk. Expression of p53 and p21 proteins and genes in the biopsies and tumor tissues of the experimental tree shrews was detected, respectively, by immunohistochemistry,and by Southem blotting and reverse transcription-polymerase chain reaction and sequencing.RESULTS: The incidence of hepatocellular carcinomas (HCC) was higher in group A (66.7%) than that in group B (3.57%) and C (30%). The time of HCC occurrence was also earlier in group A than that in group C (120.0±16.6 wk vs 153.3±5.8 wk, respectively, P<0.01). p53 protein was not detected by immunohistochemistry in all groups before the 75^th wk of the experiment. At the 105^th wk, the positive rates fo p53 were 78.6%, 60% and 71.4% in groups A, B and C, respectively, which were significantly higher than that in group D (10%) (all P<0.05). An abnormal band of p53 gene was observed in groups A and C. The mutation points of p53gene in tree shrews with HCC were at codons 275, 78 and 13. The nucleotide sequence and amino acid sequence of tree shrew's wild-type p53 showed 91.7% and 93.4% homologies with those of human p53,respectively. The immunopositivity for p21 was found before HCC development. The incidence of HCC was significantly higher in tree shrews that were positive for p21 than those negative for p21 (80.0% vs 11.0%, P<0.001).The incidence of HCC in p21 positive animals in group A was significantly higher than those positive for p21 in group C (PJian-Jia Su Yuan Li Ke-Chen Ban Liu-Liang Qin Chun Yang Chao Ou Xiao-Xian Duan Hui-Yun Wang Rui-Qi Yang Young-Lk Lee 2004World Journal of Gastroenterology2004,10,24:21
5Chinese Atherosclerosis Risk Evaluation(CARE II)study:a novel cross-sectional,multicentre study of the prevalence of high-risk atherosclerotic carotid plaque in Chinese patients with ischaemic cerebrovascular events-design and rationale显示文摘Background:Carotid atherosclerotic plaque is identified as one of the main sources of ischaemic stroke.However,the prevalence of carotid high-risk atherosclerotic plaque in Chinese patients with ischaemic cerebrovascular events has been inconsistently reported and needs to be investigated in a large population.Objectives:The primary objective of CARE II study was to determine the prevalence and characteristics of high-risk features of atherosclerotic plaques in the carotid arteries in Chinese patients with recent ischaemic stroke or transient ischaemia attack(TIA).The relationship between carotid plaque features and cerebral infarcts,the differences of carotid plaque patterns among different regions of China and the gender specific characteristics of carotid plaque will be also determined.Study design:The CARE II study will enrol 1000 patients with recent ischaemic stroke or TIA and carotid plaque from 13 hospitals and medical centres across China.In this cross-sectional,non-randomised,observational,multicentre study,all patients will undergo carotid artery MRI of bilateral carotid arteries and routine brain MRI with standardised protocols.The MRI will be interpreted at core reading centres to evaluate the characteristics of morphology and compositions of carotid plaque.Conclusions:This is a cross-sectional,multicentre study to investigate the prevalence and characteristics of high-risk atherosclerotic carotid plaque in Chinese patients with stroke and TIA by using high-resolution MRI of vessel wall.This trial is sufficiently powered to demonstrate the prevalence of carotid high-risk plaque and to explore regional differences in Chinese patients who suffered stroke.Xihai Zhao Rui Li Daniel S Hippe Thomas S Hatsukami Chun Yuan CARE-II Investigators 2017Stroke & Vascular Neurology2017,2,1:21
6Calcium channel blockers reduce severe fever with thrombocytopenia syndrome virus (SFTSV) related fatality显示文摘Severe fever with thrombocytopenia syndrome (SFTS),an emerging tick-borne infectious disease caused by a novel phlebovirus (SFTS virus, SFTSV), was listed among the top 10 priority infectious diseases by the World Health Organization due to its high fatality of 12%-50% and possibility of pandemic transmission. Currently, effective anti-SFTSV intervention remains unavailable. Here, by screening a library of FDA-approved drugs, we found that benidipine hydrochloride, a calcium channel blocker (CCB), inhibited SFTSV replication in vitro. Benidipine hydrochloride was revealed to inhibit virus infection through impairing virus internalization and genome replication. Further experiments showed that a broad panel of CCBs, including nifedipine, inhibited SFTSV infection. The anti-SFTSV effect of these two CCBs was further an a lyzed in a humanized mouse model in which CCB treatment resulted in reduced viral load and decreased fatality rate. Importantly, by performing a retrospective clinical investigation on a large cohort of 2087 SFTS patients, we revealed that nifedipine administration enhaneed virus clearance, improved clinical recovery, and remarkably reduced the case fatality rate by >5-fold. These findings are highly valuable for developing potential host-oriented therapeutics for SFTS and other lethal acute viral infections known to be inhibited by CCBs in vitro.Hao Li Lei-Ke Zhang Shu-Fen Li Shao-Fei Zhang Wei-Wei Wan Yu-Lan Zhang Qi-Lin Xin Ke Dai Yuan-Yuan Hu Zhi-Bo Wang Xiang-Tao Zhu Yu-Jie Fang Ning Cui Pan-He Zhang Chun Yuan Qing-Bin Lu Jie-Ying Bai Fei Deng Geng-Fu Xiao Wei Liu Ke Peng 2019Cell Research2019,29,9:15

8Role of Fas/FasL Pathway-mediated Alveolar Macrophages Releasing Inflammatory Cytokines in Human Silicosis显示文摘The role of Fas/Fas ligand (FasL) in mediating alveolar macrophage (AM)-derived inflammatory cytokines in 29 human lung silicosis patients and 6 controls was studied.It showed that the serum levels of IL-1β,TNF-α,IL-8,MIP-1α,MCP-1,and TGF-β1were higher in silicosis patients than in controls,and increased with the progression of silicosis except TGF-β1 and IL-8.TGF-β1,IL-8,MCP-1,MIP-1αwere efficiently down-regulated by anti-FasL antibody or caspase-8 inhibitor,indicating that Fas/FasL signaling promotes theYAO San Qiao HE Qin Cheng YUAN Ju Xiang CHEN Jie CHEN Gang LU Yao BAI Yu Ping ZHANG Chun Min YUAN Yang XU Ying Jun 2013Biomedical and Environmental Sciences2013,26,11:13
9Effect of Jinhua Qinggan granules on novel coronavirus pneumonia in patients显示文摘OBJECTIVE: To evaluate the effectiveness and safety of Jinhua Qinggan granules in the treatment of patients with novel coronavirus pneumonia(COVID-19).METHODS: Eighty cases of COVID-19 diagnosed from January 24 to February 17, 2020 in Beijing YouAn Hospital Affiliated to Capital Medical University were retrospectively analyzed. All 80 patients received symptomatic and supportive treatment.Among them, 44 patients took Jinhua Qinggan granules(treatment group) within 24 h of admission, and the remaining 36 patients either did not take Jinhua Qinggan granules or took the granules for less than 2 d(control group). In this study, we compared the duration of viral nucleic acid detection and of pneumonia absorption improvement between the two groups.RESULTS: Among the 80 cases, 37 were male(46%)and 43 were female(54%) with age ranging from15 to 86 years, with an average age of 51.19 years.The average duration of viral nucleic acid detection was(7 ± 4) d in the Jinhua Qinggan administration group and(10 ± 4) d for the control group(P =0.010), following which, nucleic acid tests were negative. Of the two groups, 56.82% in the Jinhua Qinggan treatment group and 27.78% in the control group demonstrated negative nucleic acid tests within 7 d or less. The 7-day viral clearance rate was significantly higher in the Jinhua Qinggan group compared with the control group(P = 0.009). Furthermore, the pneumonia recovery time indicated by chest CT was(8 ± 4) d in the Jinhua Qinggan group, which was significantly shorter than the control group, at(10 ± 5) d(P = 0.021). No adverse reactions were found in the treatment group after taking this medicine.CONCLUSION: In patients with COVID-19, Jinhua Qinggan granules can effectively shorten the duration of nucleic acid detection and promote the absorption of pneumonia inflammatory exudate without obvious adverse reactions.Liu Zengli Li Xiuhui Gou Chunyan Li Li Luo Xiaolan Zhang Chun Zhang Yin Zhang Jiaying Jin Aihua Li Hongyan Zeng Yuan Li Tongzeng Wang Xiaojun 2020Journal of Traditional Chinese Medicine2020,40,3:11
10Optimal proportion of wind and PV capacity in provincial power systems based on bilevel optimization algorithm under low-carbon economy显示文摘In order to boost contributions of power systems to a low-carbon economy,the installed capacity of renewable power generation,such as wind and photovoltaic(PV)power generation should be well planned.A bilevel formulation is presented to optimize the proportion of wind and PV capacity in provincial power systems,in which,carbon emissions of generator units and features of renewable resources are taken into account.In the lowerlevel formulation,a time-sequence production simulation(TSPS)model that is suitable for actual power system has been adopted.In order to maximize benefits of energy conservation and emissions reduction resulting from renewable power generation,the commercial software called General Algebraic Modeling System(GAMS)is employed to optimize the annual operation of the power system.In the upper-level formulation,the optimal pattern search(OPS)algorithm is utilized to optimize the proportion of wind and PV capacity.The objective of the upper-level formulation is to maximize benefits of energy conservation and carbon emissions reductions optimized in the lowerlevel problem.Simulation results in practical provincial power systems validate the proposed model and corresponding solving algorithms.The optimization results can provide support to policy makers to make the polices related to renewable energy.Yue YUAN Yang CAO Xinsong ZHANG Chun LIU Yuehui HUANG Peng LI Kejun QIAN 2015Journal of Modern Power Systems and Clean Energy2015,3,1:11
11Association between coexisting intracranial artery and extracranial carotid artery atherosclerotic diseases and ipsilateral cerebral infarction: a Chinese Atherosclerosis Risk Evaluation (CARE- II) study显示文摘Background To evaluate the association between coexisting intracranial and extracranial carotid artery atherosclerotic diseases and ipsilateral acute cerebral infarct(ACI)in symptomatic patients by using magnetic resonance(MR)vessel wall imaging.Methods Symptomatic patients were recruited from a cross-sectional,multicentre study of Chinese Atherosclerosis Risk Evaluation(CARE-II).All patients underwent MR imaging for extracranial carotid arterial wall,intracranial artery and brain.Coexisting intracranial stenosis≥50%and extracranial carotid artery mean wall thickness(MWT)≥1 mm and plaque compositions at the same side were evaluated and the ipsilateral ACI was identified.The association between coexisting atherosclerotic diseases and ACI was evaluated using logistic regression.Results 351 patients were recruited.Patients with ipsilateral ACI had significantly greater prevalence of coexisting intracranial stenosis≥50%and carotid MWT≥1 mm(20.5%vs 4.9%,p<0.001),calcification(15.1%vs 4.4%,p=0.001)and lipid-rich necrotic core(LRNC)(19.2%vs 7.8%,p=0.002)compared with those without.Coexisting intracranial artery stenosis≥50%and carotid MWT≥1 mm(OR 5.043,95%CI 2.378 to 10.694;p<0.001),calcification(OR 3.864,95%CI 1.723 to 8.664;p=0.001)and LRNC(OR 2.803,95%CI 1.455 to 5.401;p=0.002)were significantly associated with ipsilateral ACI.After adjusting for confounding factors,the aforementioned associations remained statistically significant(intracranial stenosis≥50%coexisting with carotid MWT≥1 mm:OR 4.313,95%CI 1.937 to 9.601,p<0.001;calcification:OR 3.606,95%CI 1.513 to 8.593,p=0.004;LRNC:OR 2.358,95%CI 1.166 to 4.769,p=0.017).Conclusions Coexistence of intracranial artery severe stenosis and extracranial carotid artery large burden and intraplaque components of calcification and LRNC are independently associated with ipsilateral ACI.Trial registration number http://gffzz1caf53c915c04334sp00b90ocp9wk6bvw.ffgz.tsg.suse.edu.cn/.Unique identifier:NCT02017756.Chunxiu Jiang Jing Zhang Jianbin Zhu Xianlong Wang Zhibo Wen Xihai Zhao Chun Yuan On behalf of CARE-II Investigators 2021Stroke & Vascular Neurology2021,6,4:11
12Oxidative Stress and Apoptotic Changes of Rat Cerebral Cortical Neurons Exposed to Cadmium in Vitro显示文摘Objective To investigate the cytotoxic mechanism of cadmium(Cd) on cerebral cortical neurons.Methods The primary cultures of rat cerebral cortical neurons were treated with different concentrations of cadmium acetate(0,5,10,and 20 μmol/L),and then the cell viability,apoptosis,ultrastructure,intracellular [Ca2+]i and reactive oxygen species(ROS) levels,mitochondrial membrane potential(ΔΨ),activities of catalase(CAT) and superoxide dismutase(SOD) were measured.Results A progressive loss in cell viability and an increased number of apoptotic cells were observed.In addition,Cd-induced apoptotic morphological changes in cerebral cortical neurons were also demonstrated by Hoechst 33258 staining.Meanwhile,ultrastructural changes were distortion of mitochondrial cristae and an unusual arrangement.Simultaneously,elevation of intracellular [Ca2+]i and ROS levels,depletion of ΔΨ were revealed in a dose-dependent manner during the exposure.Moreover,CAT and SOD activities in the living cells increased significantly.Conclusion Exposure of cortical neurons to different doses of Cd led to cellular death,mediated by an apoptotic mechanism,and the apoptotic death induced by oxidative stress may be a potential reason.And the disorder of intracellular homeostasis caused by oxidative stress and mitochondrial dysfunction may be a trigger for apoptosis in cortical neurons.YUAN Yan BIAN Jian Chun LIU Xue Zhong ZHANG Ying SUN Ya LIU Zong Ping 2012Biomedical and Environmental Sciences2012,25,2:10
13Challenges and recent progress in thermal management with heat pipes for lithium-ion power batteries in electric vehicles显示文摘Electric vehicles(EVs)are globally undergoing rapid developments,and have great potentials to replace the traditional vehicles based on fossil fuels.Power-type lithium-ion batteries(LIBs)have been widely used for EVs,owing to high power densities,good charge/discharge stability,and long cycle life.The driving ranges and acceleration performances are gaining increasing concerns from customers,which depend highly on the power level of LIBs.With the increase in power outputs,rising heat generation significantly affects the battery performances,and in particular operation safety.Meanwhile,the cold-start performance is still an intractable problem under extreme conditions.These challenges put forward higher requirements for a dedicated battery thermal management system(BTMS).Compared to traditional BTMSs in EVs,the heat pipe-based BTMS has great application prospects owing to its compact structure,flexibility,low cost,and especially high thermal conductivity.Encompassing this topic,this review first introduces heat generation phenomena and temperature characteristics of LIBs.Multiple abuse conditions and thermal runaway issues are described afterward.Typical cooling and preheating methods for designing a BTMS are also discussed.More emphasis on this review is put on the use of various heat pipes for BTMSs to enhance the thermal performances of LIBs.For lack of wide application in actual EVs,more efforts should be made to extend the use of heat pipes for constructing an energy-efficient,cost-effective,and reliable BTMS to improve the performances and safety of EVs.HUANG Yao TANG Yong YUAN Wei FANG GuoYun YANG Yang ZHANG XiaoQing WU YaoPeng YUAN YuHang WANG Chun LI JinGuang 2021Science China(Technological Sciences)2021,64,5:10
14Spatial-temporal Pattern and Differences of Land Use Changes in the Three Gorges Reservoir Area of China during 1975-2005显示文摘Regional land use changes are an important part of global changes.The research on land use changes in the Three Gorges Reservoir Area of China attracts a lot of attention owing to the Three Gorges Dam building.The Three Gorges Reservoir Area becomes one of the important research areas.This study analyzed the transforming processes and traits of each land use type and the regional differences of land use changes during the past 30 years,summarized the distribution of different land use types in different buffer zones and regresses the equation areas and different buffer distances based on buffer analyses and regression analyses,and then analyzed the transforming rules in different buffer distances,got the optimal influence distances.The research results indicate that,(1) cultivated land lies at the northwest of the reservoir and was decreasing,however,the construction land was increasing,especially the urban construction land,a large number of land was flooded because of the reservoir water level rise;(2) urban area was sprawling quickly in developed and neighboring areas,and a great deal of cultivated land and a considerable amount of grassland were occupied;in the earlier time,rural settlements occupied lots of cultivated land and a sum of forestry land in the later time;(3) the optimum influenced distances for cultivated land and forestry land were 10-35 km,and for urban and rural settlements were in 5-20 km.Overall,this research can reflect the spatial-temporal characteristics of land use changes during the 30 years,and it is helpful for urban planning and land use planning in the reservoir area.CAO Yingui ZHOU Weit WANG Jing YUAN Chun 2011Journal of Mountain Science2011,8,4:9
15Effect of co-transfection of miR-520c-3p and miR-132 on proliferation and apoptosis of hepatocellular carcinoma Huh7显示文摘Objective:To investigate the effects of co-transfection of miR-520c-3p and miR-132 on proliferation and apoptosis of hepatocellular carcinoma Huh7.Methods:Hepatocellular carcinoma Huh7 was cultured in vitro and lipidosome was used to transfect miR-520c-3p and miR-132 respectively or together.The effects of transfection of miR-520c-3p and miR-132 on proliferation and apoptosis of Huh7 were detected by CCK8 and Annexin V staining and flow cytometry,and the expression level of the targeted gene of over-expressed miR-520c-3p and miR-132 was determined by Western blot and realtime PCR.Results:Compared with the control group,the proliferation ability of Huh7 of the single transfected and co-transfected miR-520c-3p and miR-132 decreased significantly,and the apoptosis ratio increased distinctly(P<0.05).Besides,the affect of the co-transfection group was better than that of the single transfection group.The protein levels of GPC3(Glypican-3) and YAP(Yes-associated protein),the target genes transfected only by miR-520c-3p and miR-132,respectively,reduced obviously(P<0.05),which was similar with the co-infected cells,but cells transfected by miR-132 only showed a decrease of YAP.Conclusions:The co-transfection of miR-520c-3p and miR-132 can target-regulate the expression of GPC3 and YAP,enhance the exhibition effect on proliferation of hepatocellular carcinoma Huh7 and induce cell apoptosis synergistically.Chang-Jiang Lei Chun Yao De-Ke Li Zhi-Xiong Long Yuan Li Dan Tao Yan-Ping Liou Jiang-Zhou Zhang Ning Liu 2016Asian Pacific Journal of Tropical Medicine2016,9,9:9
16Polycystic ovary syndrome patients with high BMI tend to have functional disorders of androgen excess:a prospective study显示文摘Biochemical or clinical changes of hyperandrogenism are important elements of polycystic ovary syndrome(PCOS).There is currently no consensus on the definition and diagnostic criteria of hyperandrogenism in PCOS.The aim of this study was to investigate the complex symptoms of hyperandrogenic disorders and the correlations between metabolism and hyperandrogenism in patients with PCOS from an outpatient reproductive medicine clinic in China.We conducted a case control study of 125 PCOS patients and 130 controls to evaluate differences in body mass index(BMI),total testosterone(TT),modified Ferriman-Gallwey hirsutism score,sex hormone binding globulin(SHBG),homeostasis model assessment-estimated insulin resistance(HOMA-IR) and free androgen index(FAI) between PCOS patients and controls and subgroups of PCOS.The prevalence of acne and hirsutism did not differ significantly between the hyperandrogenic and non-hyperandrogenic subgroup.Patients with signs of hyperandrogenism had significantly higher BMI(P<0.05),but differences in TT,SHBG,FAI and waist/hip ratio were insignificant.The odds ratio of overweight was calculated for all PCOS patients.Our results suggest that PCOS patients with high BMI tend to have functional disorders of androgen excess;therefore,BMI may be a strong predictor of hyperandrogenism in PCOS.Chun Yuan Xiaoqiang Liu Yundong Mao Feiyang Diao Yugui Cui Jiayin Liu 2016The Journal of Biomedical Research2016,30,3:8
17Decreased Average Albumin-to-Globulin Ratio During Radiotherapy Worsens the Prognosis of Esophageal Squamous Cell Carcinoma:Implications for Nutritional Management显示文摘Objective Malnutrition and cachexia are common in esophageal squamous cell carcinoma(ESCC)patients undergoing radiotherapy.This study evaluated how malnutrition-and cachexia-related indicators,including the albumin-to-globulin ratio(AGR),and their changes during radiotherapy predict the treatment outcomes.Methods We reviewed a total of 172 ESCC patients receiving radiotherapy(as a primary cohort)and performed a Cox regression analysis on potential prognostic factors,including the AGR,as well as the TNM stage and concomitant chemotherapy.A subsequent receiver operating characteristics(ROC)curve and Kaplan Meier survival analysis was performed for ESCC patients stratified by the average AGR cut-off point.Results In addition to the well-documented factors(i.e.TNM stage and concomitant chemotherapy),the average AGR was a significant prognostic factor for ESCC patients receiving radiotherapy.By plotting the ROC curve of the average AGR with regard to the ESCC prognosis,we obtained cut-off points for the overall patients(cut-off point:1.5,AUC:0.636),for patients with stageⅡ/Ⅲdisease(cut-off point:1.5,AUC:0.611),and for patients with stageⅣdisease(cut-off point:1.84,AUC:0.900).The ESCC patients with higher average AGR had a significantly more favorable OS compared with those with a lower average AGR.Notably,ESCC patients who had an increasingΔAGR during radiotherapy had a considerably more favorable OS compared with those with a decreasingΔAGR.All of these findings were reproducible in the validation cohort.Conclusion A lower average AGR is indicative of a poorer prognosis for ESCC patients following radiotherapy.Improving the nutritional status and preventing or ameliorating cachexia might contribute to improving the prognosis of ESCC patients.Fen Cai Xiu Lian Zhang Xiao Ling Wu Ting Ting Zhuang Lei Huang Yi Fei Tu Yuan Yuan Lu Min Xia Jiang Qing Ying Zhang Yan Lin Chang Chun Ma 2021Journal of Nutritional Oncology2021,6,2:8
18Malnutrition and Quality of Life in Chinese Cancer Patients: a Clinical Study of 23,994 Subjects显示文摘Background Malnutrition is common in patients with cancer,and can negatively impact their quality of life(QoL)and even survival.However,there is currently no large data available on the prevalence of malnutrition in Chinese cancer patients.This study evaluated the prevalence of malnutrition and the QoL of Chinese patients with locoregional,recurrent or metastatic cancer.Methods We conducted a nationwide observational,multi-center,hospital-based cross-sectional study within the Chinese Society of Nutritional Oncology(CSNO)Network.All of the patients were diagnosed with one of the following 18 different types of malignant tumors:lung cancer,gastric cancer,liver cancer,colorectal cancer,breast cancer,esophageal cancer,cervical cancer,endometrial cancer,nasopharyngeal carcinoma,malignant lymphoma,leukemia,pancreatic cancer,ovarian cancer,prostate cancer,bladder cancer,brain cancer,biliary tract malignant tumors or gastrointestinal stromal tumors.These patients were enrolled from 72 hospitals located in different regions of China.The patients’nutritional status was evaluated based on the body mass index(BMI),loss of bodyweight,laboratory measurements and patient generated-subjective global assessment(PG-SGA)scores.The cancer patients’physical status and QoL were assessed by the Karnofsky Performance Status(KPS)questionnaire and the European Organization for Research and Treatment of Cancer(EORTC)QLQ-C30 questionnaire,respectively.Results From December 2013 to April 2016,23,994 patients hospitalized for cancer treatment(such as surgery,chemotherapy or radiotherapy)were enrolled in the study.The patients included 12,494(52.9%)males and 11,124(47.1%)females.The mean age was 55.8±13.7 years.The proportions of patients in cancer stagesⅠ,Ⅱ,Ⅲ,Ⅳand uncertain were 11.5%,20.3%,27.5%,30.2%and 10.5%,respectively.Among the 23,994 inpatients,the proportions of patients who were underweight(BMI<18.5 kg/m2),normal(18.5 kg/m2Hong Xia Xu Chun Hua Song Zhen Ming Fu Chang Wang Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Fu Xiang Zhou Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Min Weng Qing Hua Yao Jiu Wei Cui Wei Li Han Ping Shi the Investigation on Nutrition Status and Clinical Outcome of Common Cancers(INSCOC)Group 2021Journal of Nutritional Oncology2021,6,1:8
19Cadmium Activates Reactive Oxygen Species-dependent AKT/mT OR and Mitochondrial Apoptotic Pathways in Neuronal Cells显示文摘Objective To examine the role of Cd-induced reactive oxygen species(ROS)generation in the apoptosis of neuronal cells.Methods Neuronal cells(primary rat cerebral cortical neurons and PC12 cells)were incubated with or without Cd post-pretreatment with rapamycin(Rap)or N-acetyl-L-cysteine(NAC).Cell viability was determined by MTT assay,apoptosis was examined using flow cytometry and fluorescence microscopy,and the activation of phosphoinositide 3'-kinase/protein kinase B(Akt)/mammalian target of rapamycin(m TOR)and mitochondrial apoptotic pathways were measured by western blotting or immunofluorescence assays.Results Cd-induced activation of Akt/m TOR signaling,including Akt,m TOR,p70 S6 kinase(p70 S6K),and eukaryotic initiation factor 4E binding protein 1(4E-BP1).Rap,an m TOR inhibitor and NAC,a ROS scavenger,blocked Cd-induced activation of Akt/m TOR signaling and apoptosis of neuronal cells.Furthermore,NAC blocked the decrease of B-cell lymphoma 2/Bcl-2 associated X protein(Bcl-2/Bax)ratio,release of cytochrome c,cleavage of caspase-3 and poly(ADP-ribose)polymerase(PARP),and nuclear translocation of apoptosis-inducing factor(AIF)and endonuclease G(Endo G).Conclusion Cd-induced ROS generation activates Akt/m TOR and mitochondrial pathways,leading to apoptosis of neuronal cells.Our findings suggest that m TOR inhibitors or antioxidants have potential for preventing Cd-induced neurodegenerative diseases.YUAN Yan WANG Yi HU Fei Fei JIANG Chen Yang ZHANG Ya Jing YANG Jin Long ZHAO Shi Wen GU Jian Hong LIU Xue Zhong BIAN Jian Chun LIU Zong Ping 2016Biomedical and Environmental Sciences2016,29,2:8
