| 1 | Fast increasing of surface ozone concentrations in Pearl River Delta characterized by a regional air quality monitoring network during 2006–2011显示文摘Based on the observation by a Regional Air Quality Monitoring Network including 16 monitoring stations, temporal and spatial variations of ozone(O3), NO2and total oxidant(Ox) were analyzed by both linear regression and cluster analysis. A fast increase of regional O3concentrations of 0.86 ppbV/yr was found for the annual averaged values from 2006 to 2011 in Guangdong, China. Such fast O3increase is accompanied by a correspondingly fast NOx reduction as indicated by a fast NO2 reduction rate of 0.61 ppbV/yr. Based on a cluster analysis, the monitoring stations were classified into two major categories – rural stations(non-urban) and suburban/urban stations. The O3concentrations at rural stations were relatively conserved while those at suburban/urban stations showed a fast increase rate of 2.0 ppbV/yr accompanied by a NO2 reduction rate of 1.2 ppbV/yr. Moreover, a rapid increase of the averaged O3 concentrations in springtime(13%/yr referred to 2006 level) was observed, which may result from the increase of solar duration, reduction of precipitation in Guangdong and transport from Eastern Central China. Application of smog production algorithm showed that the photochemical O3production is mainly volatile organic compounds(VOC)-controlled. However, the photochemical O3production is sensitive to both NOx and VOC for O3pollution episode. Accordingly, it is expected that a combined NOx and VOC reduction will be helpful for the reduction of the O3 pollution episodes in Pearl River Delta while stringent VOC emission control is in general required for the regional O3 pollution control. | Jinfeng Li Keding Lu Wei Lv Jun Li Liuju Zhong Yubo Ou Duohong Chen Xin Huang Yuanhang Zhang | 2014 | Journal of Environmental Sciences2014，26，1： | 51 |
| 2 | Association between Vitamin D Insufficiency and the Risk for Gestational Diabetes Mellitus in Pregnant Chinese Women显示文摘Objective To investigate the association between vitamin D deficiency and risk of gestational diabetes mellitus(GDM) in pregnant Chinese women.Methods A nested case-control study was conducted.Clinical and biochemical data were analyzed for 200 subjects with GDM and 200 subjects with normal glucose tolerance(NGT).Results The median(interquartile range) serum 25-hydroxyvitamin D(25OHD) levels were 22.39(17.67,29.38) and 25.86(19.09,34.88) nmol/L in the GDM and NGT groups,respectively.Rates of 25OHD deficiency or insufficiency were significantly higher in the GDM group than in the NGT group.Subjects with 25OHD levels <25 nmol/L had a 1.8-fold higher risk of GDM compared with subjects with higher vitamin D levels.In the GDM group,serum 25OHD was independently associated with HbA1c and insulin resistance after adjusting for confounding factors.In the NGT group,serum 25OHD was independently associated with fasting plasma glucose and systolic blood pressure after adjusting for maternal age and other confounding factors.Conclusion 25OHD insufficiency is very common in Chinese women.Low 25OHD status may be associated with insulin resistance and act as a risk factor for GDM. | WANG Ou NIE Min HU Ying Ying ZHANG Kui LI Wei PING Fan LIU Jun Tao CHEN Li Meng XING Xiao Ping | 2012 | Biomedical and Environmental Sciences2012，25，4： | 21 |
| 3 | Impact of Heat Wave in 2005 on Mortality in Guangzhou, China显示文摘Objective To assess the impact of the heat wave in 2005 on mortality among the residents in Guangzhou and to identify susceptible subpopulations in Guangzhou, China. Methods The data of daily number of deaths and meteorological measures from 2003 to 2006 in Guangzhou were used in this study. Heat wave was defined as ≥7 consecutive days with daily maximum temperature above 35.0 ℃ and daily mean temperature above the 97th percentile during the study period. The excess deaths and rate ratio (RR) of mortality in the case period compared with the reference period in the same summer were calculated. Results During the study period, only one heat wave in 2005 was identified and the total number of excess deaths was 145 with an average of 12 deaths per day. The effect of the heat wave on non-accidental mortality (RR=1.23, 95% CI: 1.11-1.37) was found with statistically significant difference. Also, greater effects were observed for cardiovascular mortality (RR=1.34, 95% CI: 1.13-1.59) and respiratory mortality (RR=1.31, 95% CI: 1.02-1.69). Females, the elderly and people with lower socioeconomic status were at significantly higher risk of heat wave-associatedmortality. Conclusion The 2005 heat wave had a substantial impact on mortality among the residents in Guangzhou, particularly among some susceptible subpopulations. The findings from the present study may provide scientific evidences to develop relevant public health policies and prevention measures aimed at reduction of preventable mortality from heat waves. | YANG Jun LIU Hua Zhang OU Chun Quan LIN Guo Zhen DING Yan ZHOU Qin SHEN Ji Chuan CHEN Ping Yan | 2013 | Biomedical and Environmental Sciences2013，26，8： | 16 |

| 7 | IL-25 stimulates M2 macrophage polarization and thereby promotes mitochondrial respiratory capacity and lipolysis in adipose tissues against obesity显示文摘Obesity and associated metabolic diseases are characterized by a chronic low-grade inflammatory state with the infiltration of many inflammatory cells,especially macrophages.Immune molecules,including some cytokines,have a close relationship with metabolism.Interleukin(IL)-25 is a member of the IL-17 cytokine family that can regulate macrophages and alleviate some metabolic dysfunction;however,its role and mechanisms in lipid metabolism remain to be extensively clarified.Human serum and liver biopsy specimens,high-fat diet-induced obesity mice and DB/DB(Lepr−/−)animal models were used to examine IL-25 expression in obesity and nonalcoholic fatty liver diseases(NAFLD).To observe the role of IL-25 in lipid metabolism,model mice were administered with IL-25 or adoptively transferred with IL-25-educated macrophages in vivo,whereas bone marrow-derived macrophages,the macrophage cell line RAW264.7 and adipocytes differentiated from 3T3-L1 were used in vitro.IL-25 was decreased in NAFLD patients and obese mice.In addition,IL-25 reduced body weight gain and lipid accumulation,enhanced lipid uptake by macrophages and increased the expression of lipolysis andβ-oxidation enzymes via alternatively activating macrophages.IL-25 also promoted lipolysis and suppressed lipogenesis in adipocytes co-cultured with the IL-25-educated macrophages.Furthermore,IL-25 improved the mitochondrial respiratory capacity and oxygen consumption rate of macrophages and produced more NAD+/NADH and ATP.In conclusion,IL-25 can stimulate M2 macrophage polarization and thereby promote lipolysis and mitochondrial respiratory capacity,highlighting the potential for IL-25 to be used as a therapeutic agent against obesity and associated metabolic syndromes. | Juan Feng Lingyi Li Zhiying Ou Qiao Li Baoyong Gong Zhenxian Zhao Weiwei Qi Ti Zhou Jun Zhong Weibin Cai Xia Yang Aiping Zhao Guoquan Gao Zhonghan Yang | 2018 | Cellular & Molecular Immunology2018，15，5： | 10 |
| 8 | Two clinically relevant pressures of carbon dioxide pneumoperitoneum cause hepatic injury in a rabbit model显示文摘AIM:To observe the hepatic injury induced by carbon dioxide pneumoperitoneum(CDP) in rabbits,compare the eects olow-and high-pressure pneumoperitoneum,and to determine the degree o hepatic injury induced by these two clinically relevant CDP pressures.METHODS:Thirty healthy male New Zealand rabbits weighing 3.0 to 3.5 kg were randomly divided into three groups(n = 10 for each group) and subjected to the ollowing to CDP pressures:no gas control,10 mmHg,or 15 mmHg.Histological changes in liver tissues were observed with hematoxylin and eosin staining and transmission electron microscopy.Liver unction was evaluated using an automatic biochemical analyzer.Adenine nucleotide translocator(ANT) activity in liver tissue was detected with the atractyloside-inhibitor stop technique.Bax and Bcl-2 expression levels were detected bywestern blotting.RESULTS:Liver Functions in the 10 mmHg and 15 mmHg experimental groups were significantly disturbed compared with the control group.After CDP,the levels or alanine transaminase and aspartate transaminase were 77.3 ± 14.5 IU/L and 60.1 ± 11.4 IU/L,respectively,in the 10 mmHg experimental group and 165.1 ± 19.4 IU/L and 103.8 ± 12.3 IU/L,respectively,in the 15 mmHg experimental group,which were all higher than those of the control group(p < 0.05).There was no difference in pre-albumin concentration between the 10 mmHg experimental group and the control group,but the prealbumin level of the 15 mmHg experimental group was significantly lower than that of the control group(p < 0.05).No significant differences were observed in the levels of total bilirubin or albumin among the three groups.After 30 and 60 min of CDP,pH was reduced(p < 0.05) and fa CO2 was elevated(p < 0.05) in the 10 mmHg group compared with controls,and these changes were more pronounced in the 15 mmHg group.Hematoxylin and eosin staining showed no significant change in liver morphology,except for mild hyperemia in the two experimental groups.Transmission electron microscopy showed mild mitochondrial swelling in hepatocytes of the 10 mmHg group,and this was more pronounced in the 15 mmHg group.No significant difference in ANT levels was found between the control and 10 mmHg groups.However,ANT concentration was significantly lower in the 15 mmHg group compared with the control group.The expression of hepatic Bax was significantly increased in the two experimental groups compared with the controls,but there were no differences in Bcl-2 levels among the three groups.Twelve hours after CDP induction,the expression of hepatic Bax was more significant in the 15 mmHg group than in the 10 mmHg group.CONCLUSION:A CDP pressure of 15 mmHg caused more substantial hepatic injury,such as increased levels of acidosis,mitochondrial damage,and apoptosis;therefore,10 mmHg CDP is preferable for laparoscopic operations. | Jun Li Ying-Hai Liu Zhan-Yong Ye He-Nian Liu Shan Ou Fu-Zhou Tian | 2011 | World Journal of Gastroenterology2011，17，31： | 10 |

| 12 | Validity of the Chinese Version of the Patient-Generated Subjective Global Assessment (PG-SGA) in Lung Cancer Patients显示文摘The prevalence of malnutrition is high among oncology patients in China. Although the Patient- Generated Subjective Global Assessment (PG-SGA) is widely recognized as an important nutritional assessment tool, it has not been validated for Chinese cancer patients. The purpose of this study was to conduct an analysis of nutrition screening and assessment data to validate the Chinese version of the PG-SGA in Chinese patients with lung cancer. This was an observational, cross-sectional study of 2,000 consecutive adult patients with lung cancer treated at several tertiary hospitals in China. Anthropometric and patient descriptive data were collected. The PG-SGA generated a score for the nutritional risk and a global rating for the nutritional status. The internal consistency, external consistency, and construct validity were evaluated, and a known-groups comparison and principal component analyses were conducted to evaluate the reliability and validity of the PG-SGA. The known-groups comparison demonstrated the ability of the PG-SGA to differentiate lung cancer patients of different nutritional and body mass index (BMI) groups. A confirmatory factor analysis supported the original four-factor structure of the PG-SGA. In terms of the internal and external consistency, the PG-SGA demonstrated intra-class correlation coefficients (ICC) up to 0.987. Alternative form validity was also demonstrated between Box 4 of the PG-SGA and the Karnofsky Performance Status score, with excellent external consistency (r = 0.972, P < 0.001). The construct validity was supported, and selected questionnaire dimensions were evident in the principal component analysis. Significant Spearman correlations (P < 0.001) were demonstrated. The Chinese version of the PG-SGA demonstrated significant reliability and sufficient exploratory properties to support its validity. It seems to be a valid tool that can be used to access the nutritional status of Chinese lung cancer patients. The validity of the PG-SGA in Chinese cancer patients warrants further investigation in other cancer types. | Zhen Ming Fu Hong Xia Xu Chun Hua Song Wei Li 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 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 Chang Wang Han Ping Shi The Investigation on Nutrition Status and Clinical Outcome of Common Cancers (INSCOC) Group | 2016 | Journal of Nutritional Oncology2016，1，1： | 7 |
| 13 | Fiber damage analysis model for RC beam-column based on EEP super-convergent computation显示文摘A new numerical strategy to model nonlinear damage behavior of RC beam-column member based on level of material and superconvergent computation is presented in this paper. A fiber damage analysis model (FDAM) for RC beam-column member is established by analyzing section of fiber beam column element with the uniaxial damage constitutive relations of con-crete. The damage index of RC member through statistical analysis of concrete fibers damage is defined in the extreme section of beam elements, which can describe the nonlinear damage behavior of RC beam-column member under any loadings. The newly proposed element energy projection (EEP) method is applied to the inelastic analysis of FDAM. EEP superconvergent formulas for section forces and deformations of beam-column are established, and general algorithm and numerical strategy adopting EEP super-convergent computation for section deformation increment are proposed in the classical Newton-Raphson process. Both analysis and numerical test show that the EEP method can effectively find out the nonlinear feature of the distribution, and accurately obtain the damage distribution of RC beamcolumn. The proposed numerical scheme in this paper proves to be effective and convenient in its use and can be easily integrated into the present inelastic FEM programs of structure analysis. | TENG Jun LI ZuoHua OU JinPing HE XueFeng | 2011 | Science China(Technological Sciences)2011，54，10： | 6 |
| 14 | The Impact of Relative Humidity and Atmospheric Pressure on Mortality in Guangzhou, China显示文摘Objective Although many studies have examined the effects of ambient temperatures on mortality, little evidence is on health impacts of atmospheric pressure and relative humidity. This study aimed to assess the impacts of atmospheric pressure and relative humidity on mortality in Guangzhou, China. Methods This study included 213,737 registered deaths during 2003-2011 in Guangzhou, China. A quasi-Poisson regression with a distributed lag non-linear model was used to assess the effects of atmospheric pressure/relative humidity. Results We found significant effect of low atmospheric pressure/relative humidity on mortality. There was a 1.79%(95% confidence interval: 0.38%-3.22%) increase in non-accidental mortality and a 2.27%(0.07%-4.51%) increase in cardiovascular mortality comparing the 5th and 25 th percentile of atmospheric pressure. A 3.97%(0.67%-7.39%) increase in cardiovascular mortality was also observed comparing the 5th and 25 th percentile of relative humidity. Women were more vulnerable to decrease in atmospheric pressure and relative humidity than men. Age and education attainment were also potential effect modifiers. Furthermore, low atmospheric pressure and relative humidity increased temperature-related mortality. Conclusion Both low atmospheric pressure and relative humidity are important risk factors of mortality. Our findings would be helpful to develop health risk assessment and climate policy interventions that would better protect vulnerable subgroups of the population. | OU Chun Quan YANG Jun OU Qiao Qun LIU Hua Zhang LIN Guo Zhen CHEN Ping Yan QIAN Jun GUO Yu Ming | 2014 | Biomedical and Environmental Sciences2014，27，12： | 5 |
| 15 | Validity of the Chinese Version of the Patient-Generated Subjective Global Assessment (PG-SGA) in Gastric Cancer Patients显示文摘Purpose Malnutrition is severe among gastric cancer patients in China. While the Patient-Generated Subjective Global Assessment (PG-SGA) is a widely used nutritional assessment tool, the validation for Chinese patients with gastric cancer has not been performed yet. The aim of this research is to validate the Chinese version of the PGSGA in Chinese gastric cancer patients by conducting analyses of nutrition screening and assessment data. Methods Two thousand consecutive adult patients with gastric cancer were included in this observational, cross-sectional study in several tertiary hospitals in China. A survey was made among those patients, which included several questionnaires and some anthropometric parameters. We calculated the parameters to validate the use of PG-SGA categorizing the nutritional status of gastric cancer patients. Then we performed statistical analysis to evaluate the internal consistency, external consistency, and construct validity. Results This study verified the ability of the PG-SGA to differentiate gastric cancer patients into different nutritional groups. The confirmatory factor analysis verified the original four-factor structure of the PG-SGA. The internal and external consistency was measured by a concordance analysis which showed an intraclass correlation coefficients (ICC) of 0.987. The correlations of the Box 4 score with the Karnofsky performance status score demonstrated alternative form validity with good external consistency (Pearson, r = 0.643, P < 0.001). All three anthropometric dimensions of the PG-SGA were supported by principal component analysis. Spearman correlations (P < 0.001) were significant in the majority of tests. Conclusion The Chinese version of the PG-SGA is a valid tool to access the patients’ nutritional status for Chinese gastric patients. | Zhen Ming Fu Hong Xia Xu Chun Hua Song Wei Li 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 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 Chang Wang Han Ping Shi The Investigation on Nutrition Status and Clinical Outcome of Common Cancers (INSCOC) Group | 2018 | Journal of Nutritional Oncology2018，3，4： | 5 |
| 16 | RELATIONSHIP BETWEEN CYCLIN G1 AND HUMAN PAPILLOMA VIRUS INFECTION IN CERVICAL INTRAEPITHELIAL NEOPLASIA AND CERVICAL CARCINOMA显示文摘Objective To evaluate the overexpression of cyclin G1 in cervical intraepithelial neoplasia (CIN) and cervical carcinoma, and the correlation between cyclin G1 and high-risk human papilloma virus (HPV) infection. Methods All of the specimens were obtained from the Department of Pathology of China-Japan Friendship Hospital from January 2000 to August 2004.We detected the expression of cyclin G1 with immunohistochemistry, HPV16/18 infection with in situ hybridization, and high-risk HPV infection with Hybrid capture system II (HC-II) in normal group (25 cases), CIN I (48 cases), CIN II (56 cases), CIN III (54 cases), and invasive cervical squamous-cell carcinoma (SCC, 31 cases). Results The positive rates of cyclin G1 expression in CIN(77.85%)and SCC cervical tissues (87.10%) were significantly higher than normal (8.00%, P<0.01), and the intensities of cyclin G1 expression in CIN(40.60%)and SCC cervical tissues (61.51%) were significantly higher than normal (2.72%, P<0.05). The positive rates and intensities of cyclin G1 expression increased gradually with the grade of cervical lesions. High-risk HPV infection rates were higher in CIN and SCC than normal groups (P<0.05). There was a positive correlation between cyclin G1 expression and high-risk HPV infection detected with HC-II (Kendall’s tau-b=0.316, 0.269, 0.352, and 0.474 in CIN I, CINII, CIN III, and SCC, respectively, P<0.05). Conclusions Cyclin G1 is overexpressed in CIN and SCC. Cyclin G1 may be a biomarker for detecting CIN and SCC. Cyclin G1 may play an important role in the oncogenesis of CIN and SCC by high-risk HPV infection. | Jing Liang Mei-lu Bian Qing-yun Chen Xia Liu Hua Ou Min Li Jun Liu | 2006 | Chinese Medical Sciences Journal2006，21，2： | 5 |
| 17 | A Modified Certainty Coefficient Method(M-CF) for Debris Flow Susceptibility Assessment:A Case Study for the Wenchuan Earthquake Meizoseismal Areas显示文摘In the meizoseismal areas hit by the China Wenchuan earthquake on May 12, 2008, the disasterprone environment has changed dramatically, making the susceptibility assessment of debris flow more complex and uncertain. After the earthquake, debris flow hazards occurred frequently and effective susceptibility assessment of debris flow has become extremely important. Shenxi gully in Du Jiangyan city, located in the meizoseismal areas, was selected as the study area. Based on the research of disaster-prone environment and the main factors controlling debris flow, the susceptibility zonations of debris flow were mapped using factor weight method(FW), certainty coefficient method(CF) and geomorphic information entropy method(GI). Through comparative analysis, the study showed that these three methods underestimated susceptible degree of debris flow when used in the meizoseismal areas of Wenchuan earthquake. In order to solve this problem, this paper developed a modified certainty coefficient method(M-CF) to reflect the impact of rich loose materials on the susceptible degree of debris flow. In the modified method, the distribution and area of loose materials were obtained by field investigations and postearthquake remote sensing image, and four data sets, namely, lithology, elevation, slop and aspect, wereused to calculate the CF values. The result of M-CF method is in agreement with field investigations and the accuracy of the method is satisfied. The method has a wide application to the susceptibility assessment of debris flow in the earthquake stricken areas. | WANG Jun YU Yan YANG Shun LU Gui-hong OU Guo-qiang | 2014 | Journal of Mountain Science2014，11，5： | 4 |
| 18 | Debris Flow Formation Process and Critical Hydrodynamic Conditions in the Meizoseismal Area of the Wenchuan Earthquake显示文摘The Wenchuan earthquake generated strong surface disturbances and triggered a large number of loose deposits, resulting in the disasterprone environment with special watershed hydrological characteristics. This paper was to propose a debris flow formation process and explore the permeability characteristics and critical hydrodynamic conditions of the loose deposits triggered by the earthquake. The Guo Juanyan gully(31°05′27″ N to 31°05′46″ N, 103°36′58″ E to 103°37′09″ E) in Du Jiangyan City, located in the meizoseismal areas of the Wenchuan earthquake, was chosen as the study area and the disaster-prone environment was analyzed. The formation process of the debris flow was first proposed using a stability analysis, and then, the permeability characteristics of loose deposits were determined via in situ permeability experiments. Finally, the critical 1 h rainfall was simulated through a distributed hydrological model and verified by field observations. The formation process of debris flow could be divided into three stages based on the relationship between the hydrodynamic force and loose deposit resistance. The critical 1 h rainfall amounts under three antecedent moisture conditions(I-dry, II-normal and III-wet) were 52 mm/h, 43 mm/h and 34 mm/h, respectively. This study proposed a debris flow formation process in the meizoseismal areas of the Wenchuan earthquake based on the stability analysis and defined the rainfall threshold for debris flow early warning at the local level, which is significant for debris flow mitigation and risk management. | WANG Jun YU Yan PAN Hua-li QIAO Cheng OU Guo-qiang | 2015 | Journal of Mountain Science2015，12，3： | 4 |

A new lower bound of the centered L2 -discrepancy values of combined designs is obtained, which can be used as a benchmark for searching optimal foldover plans. Our numerical results show that this lower bound is sharper than existing results when more factors reverse the signs in the initial design. | Yi Ju LEI Zu Jun OU Hong QIN Na ZOU | 2012 | Acta Mathematica Sinica,English Series2012，28，4： | 4 |
| 20 | p53 isoform △113p53/△133p53 promotes DNA double-strand break repair to protect cell from death and senescence in response to DNA damage显示文摘在 DNA 双海滨的 p53 的禁止的角色裂缝(DSB ) 修理对它的压制肿瘤的性质似乎矛盾。p53 isoform Δ 113p53/Δ 133p53 是反对 p53 apoptotic 的 p53 目标基因活动。然而,它在 DNA 损坏修理的功能的信息正在缺乏。这里,我们报导那 Δ 113p53 表示被 γ 强烈导致; -irradiation, 然而并非由紫外照耀或热电震疗法。惊人地, Δ 113p53 支持 DNA DSB 修理小径包括相应再结合,非相应的结束加入并且单个海滨的退火。学习 Δ 的生物意义;在支持 DNA DSB 修理的 113p53,我们产生了 zebrafish Δ 113p53 经由抄写的 M/M 异种像使活跃之物的受动器核酸酶技术并且发现异种对 γ 更敏感;照耀。人的 ortholog, Δ 133p53,被 γ 仅仅也导致;照耀和功能修理支持 DNA DSB。Δ 133p53-knockdown 房间响应 γ 在以后的阶段在 G2 阶段被逮捕;照耀由于 unrepaired DNA DSB 的高水平,它最后导致了房间老朽。而且, Δ 113p53/Δ 133p53 经由 upregulating 支持 DNA DSB 修理由到在他们的倡导者的 p53 应答的元素的一种新奇类型的绑定的修理基因 rad51, lig4 和 rad52 的抄写。我们的结果表明那 Δ 113p53/Δ 133p53 是为由阻止 apoptosis 并且支持 DNA DSB 修理禁止房间老朽的 DNA 损坏应力的一个进化地保存的支持幸存的因素。我们的数据也建议 Δ 的正式就职;在正常房间或纸巾的 133p53 表示为癌症病人提供一个重要忍耐标记给放射疗法。 | Lu Gong Hongjian Gong Xiao Pan Changqing Chang Zhao Ou Shengfan Ye Le Yin Lina Yang Ting Tao Zhenhai Zhang Cong Liu David P Lane Jinrong Peng Jun Chen | 2015 | Cell Research2015，25，3： | 4 |
