| 1 | Effect of Xiaoaiping injection on advanced hepatocellular carcinoma in patients显示文摘OBJECTIVE: To investigate the effect of Xiaoaiping Injection (XAP) on advanced hepatocellular carcinoma (HCC) in patients. METHODS: Sixty-eight patients with advanced HCC were assigned to a control group of 36 and a treatment group of 32.The control group was treated with best supportive treatment (BST) and the treatment group was given XAP plus BST. XAP was administered daily by iv and the treatment course was lasted for 30 days for both groups.The immediate therapeutic efficacy, Karnofsky performance status (KPS) scores, and the changes in immunity indicators (CD3+, CD4+ and CD8+ T cells) were measured and compared before and after treatment. The progression-free survival (PFS) rate and overall survival (OS) rate in the 2 groups were analyzed. RESULTS: The immediate therapeutic efficacy and KPS of the treatment group were better than those in the control group (P<0.05). Patients in the treat-ment group had higher percentages of CD3 and CD4 T-lymphocytes in peripheral blood than those in the control group (P<0.05). The median survival time was 27.0 weeks in the treatment group and 24.5 weeks in the control group. The 6-months cumulative survival rates in the treatment and control groups were 33.3% and 25.0% , respectively, with no significant difference (P>0.05). The PFS was 18 weeks in the treatment group and 15 weeks in control group (P<0.05). CONCLUSION: XAP enhances the quality of life (QOL) of patients with advanced HCC, improves their immunity and extends their PFS. | Zhengrong Huang Yong Wang Jiajun Chen Rongping Wang Qiang Chen | 2013 | Journal of Traditional Chinese Medicine2013，33，1： | 22 |
| 2 | Sea surface temperature records of core ZY2 from the central mud area in the South Yellow Sea during last 6200 years and related effect of the Yellow Sea Warm Current显示文摘Sea surface temperature (SST) records in the South Yellow Sea during the last 6200 years are reconstructed by the unsaturation index of long-chain alkenones (K 37 U ') in sediment core ZY2 from the central mud area.The SST records varied between 14.1 and 16.5°C (15.6°C on average),with 3 phases:(1) A high SST phase at 6.2-5.9 cal ka BP;(2) A low and intensely fluctuating SST phase at 5.9-2.3 cal ka BP;and (3) A high and stable SST phase since 2.3 cal ka BP.Variation of the SST records is similar to intensity of the Kuroshio Current (KC),and corresponds well in time to global cold climate events.However,the amplitude of the SST response to cooling events was significantly different in different phases.The SST response to global cooling event was weak while the KC was strong;and the SST response was strong while the KC was weak.The difference in amplitude of the SST response is possibly caused by the modulation effect of the Yellow Sea Warm Current which acts as a shelf branch of the KC and a compensating current induced by the East Asia winter monsoon.The warm waters brought by the Yellow Sea Warm Current cushion the SST decrease induced by climate cooling,and both the Kuroshio and East Asian winter monsoon play important roles in the modulation mechanism.The SST records display a periodicity of 1482 years.The same period was found in the KC records,indicating that variation of the SST records in the central South Yellow Sea is strongly affected by KC intensity.The same period was also found in Greenland ice cores and North Atlantic and Arabian Sea sediment cores,showing a regional response of marine environmental variability in the East China Seas to that in the global oceans. | WANG LiBo YANG ZuoSheng ZHANG RongPing FAN DeJiang ZHAO MeiXun HU BangQi | 2011 | Chinese Science Bulletin2011，56，15： | 13 |
| 3 | Biomarker Records of Phytoplankton Productivity and Community Structure Changes in the Central Yellow Sea Mud Area During the Mid-Late Holocene显示文摘The Yellow Sea(YS)environmental and ecological changes during the Holocene are driven by the interactions between the Yellow Sea Warm Current(YSWC),the East Asian Winter Monsoon(EAWM)and the Kuroshio Current(KC).We report marine biomarker records of brassicasterol,dinosterol and C37 alkenones in core ZY1 and core ZY2 from the South Yellow Sea(SYS)to reconstruct the spatial/temporal variations and possible mechanisms of phytoplankton primary productivity and community structure changes during the Mid-late Holocene.The contents of the corresponding biomarkers in the two cores are similar,and they also reveal broadly similar temporal trends.From 6 kyr to 3 kyr,the biomarker contents in the two cores were relatively low with small oscillations,followed by a distinct increase at about 3 kyr indicating productivity increases caused by a stronger EAWM.The alkenone/brassicasterol ratio(A/B)is used as a community structure proxy,which also showed higher values in both cores since 3 kyr,indicating increased haptophyte contribution to total productivity.It is proposed that the YS community structure has been mainly influenced by the YSWC,with stronger YSWC influences causing an increase in haptophyte contribution since 3 kyr.Some differences of the biomarker records between ZY2 and ZY1 suggest spatial variations in response to YSWC and KC forcing.When the KC was intensified during the periods of 6 4.2 kyr and 1.7 0 kyr,the YSWC extended eastward,exerting more influence on core ZY1.On the other hand,when the KC weakened during 4.2 1.7 kyr,the YSWC extended westward,exerting more influence on the ZY2. | ZHAO Xiaochen TAO Shuqin ZHANG Rongping ZHANG Hailong YANG Zuosheng ZHAO Meixun | 2013 | Journal of Ocean University of China2013，12，4： | 11 |

| 5 | Do anogenital gland secretionsof giant panda code for their sexual ability?显示文摘To test the hypothesis of whether ano- genital gland secretions (AGS) of giant panda code for their sexual ability, we collected AGS samples of 11 male (5 adult and 6 subadult) and 14 female (7 adult and 7 subadult) captive giant pandas (Ailuro- poda melanoleuca) from China Research and Con- servation Center for the Giant Panda at Wolong, Si- chuan, China from 1994 to 2002. The samples were analyzed by GC and GC-MS. The GC results showed that male and female pandas shared 20 constituents with equal capacity factors in the AGS. Further GC-MS analyses showed that there were a total of 95 compounds in the AGS. Nine constituents for the males and three for the females differed significantly in relative abundances between sexually active and inactive individuals, but no clear division between sexually active and inactive pandas by hierarchical cluster analyses on the relative abundances of a subset of 56 compounds. However, we were able to separate different age groups of male pandas by the constituents of AGS. 14 compounds were found sig- nificantly and negatively, and 8 compounds positively, correlated with pandas’ age by year. Our results suggest that the information contained in the AGS of panda might not code for pandas’ sexual ability but might for their age. These results will be valuable for captive breeding and conservation in the wild. | LIU Dingzhen YUAN Hong TIAN Hong WEI Rongping ZHANG Guiquan SUN Lixing WANG Liwen SUN Ruyong | 2006 | Chinese Science Bulletin2006，51，16： | 7 |

| 7 | Enhancing China's Innovation Performance:The Policy Choices显示文摘Transforming China into an innovation-driven economy has been one of the top priorities of the Chinese Government.This paper examines the policy choices involved in the extended national innovation performance framework for creating an open innovation system.Innovation capabilities,incentives and institutional frameworks are examined.The paper argues that China should continue to increase its investment in R&D and in education,and that there should also be an attempt to strengthen the incentive system at the macro,meso and micro levels.This strengthening may include reforms to:release the power of competition and guide resources towards innovative sectors;adopt appropriate human resource management,such as appraisal and remuneration systems;create effective policies for research funding management;and evaluate the efficiency of research to encourage the creativity of researchers,managers and employees.The paper also discusses the space for industrial policy in the 21 st century. | Xiaolan Fu Rongping Mu | 2014 | China & World Economy2014，22，2： | 6 |
| 8 | Male panda (Ailuropoda melanoleuca) urine contains kinship information显示文摘Chemical communication plays an important role in kin selection and mate choice in mammals. The covariance of odor-genes of rodents has been documented and kinship odor has been proposed and termed, yet little is known of the relationship between genetic relatedness and chemical composition of kinship odors. Giant pandas (Ailuropoda melanoleuca) rely substantially on chemical communication to mediate their social interactions. To examine the relationship between genetic relatedness and compounds in the urine/anogenital gland secretions, we compared the similarities between genetic relatedness and the chemical profiles of anogenital gland secretions and urine via lineage construction and GC-MS (gas chromatography and mass spectrometry). We found that information about kinship odors was present only in the urine of male adults in the mating season but absent in the non-mating season. Adult females and all sub-adults did not have such kinship odors in either mating or non-mating season. Therefore, kinship odor in the panda was contingent on age, sex, and season. This is the first report about the condition-dependent expression of kinship odor, which may have a sig- nificant implication in the practice of panda conservation in relation to chemical communication and sexual selection. | LIU DingZhen WEI RongPing ZHANG GuiQuan YUAN Hong WANG ZhiPeng SUN Lixing ZHANG Jianxu ZHANG HeMin | 2008 | Chinese Science Bulletin2008，53，18： | 6 |
| 9 | Progressive loss of striatal dopamine terminals in MPTP-induced acute parkinsonism in cynomolgus monkeys using vesicular monoamine transporter type 2 PET imaging([^(18)F]AV-133)显示文摘The 1-methyl-4-phenyl-1,2,3,4-tetrahydropyridine(MPTP)-induced parkinsonism model, particularly in non-human primates, remains the gold-standard for studying the pathogenesis and assessing novel therapies for Parkinson's disease. However, whether the loss of dopaminergic neurons in this model is progressive remains controversial, mostly due to the lack of objective in vivo assessment of changes in the integrity of these neurons. In the present study, parkinsonism was induced in cynomolgus monkeys by intravenous administration of MPTP(0.2 mg/kg) for 15 days; stable parkinsonism developed over 90 days, when the symptoms were stable. Noninvasive positron emission tomographic neuroimaging of vesicular monoamine transporter 2 with 9-[18F]fluoropropyl-(+)-dihydrotetrabenazine([18F]AV-133) was used before, and 15 and 90 days after the beginning of acute MPTP treatment. The imaging showed evident progressive loss of striatal uptake of [18F]AV-133. The dopaminergic denervation severity had a significant linear correlation with the clinical rating scores and the bradykinesia subscores. Thesefindings demonstrated that [18F]AV-133 PET imaging is a useful tool to noninvasively evaluate the evolution of monoaminergic terminal loss in a monkey model of MPTP-induced parkinsonism. | Yajing Liu Feng Yue Rongping Tang Guoxian Tao Xiaomei Pan Lin Zhu Hank F.Kung Piu Chan | 2014 | Neuroscience Bulletin2014，30，3： | 6 |
| 10 | Chinese expert consensus on conversion therapy for hepatocellular carcinoma(2021 edition)显示文摘Recent advances in systemic and locoregional treatments for patients with unresectable or advanced hepatocellular carcinoma(HCC)have resulted in improved response rates.This has provided an opportunity for selected patients with initially unresectable HCC to achieve adequate tumor downstaging to undergo surgical resection,a‘conversion therapy’strategy.However,conversion therapy is a new approach to the treatment of HCC and its practice and treatment protocols are still being developed.Review the evidence for conversion therapy in HCC and develop consensus statements to guide clinical practice.Evidence review:Many research centers in China have accumulated significant experience implementing HCC conversion therapy.Preliminary findings and data have shown that conversion therapy represents an important strategy to maximize the survival of selected patients with intermediate stage to advanced HCC;however,there are still many urgent clinical and scientific challenges for this therapeutic strategy and its related fields.In order to summarize and learn from past experience and review current challenges,the Chinese Expert Consensus on Conversion Therapy for Hepatocellular Carcinoma(2021 Edition)was developed based on a review of preliminary experience and clinical data from Chinese and non-Chinese studies in this field and combined with recommendations for clinical practice.Sixteen consensus statements on the implementation of conversion therapy for HCC were developed.The statements generated in this review are based on a review of clinical evidence and real clinical experience and will help guide future progress in conversion therapy for patients with HCC. | Hui-Chuan Sun Jian Zhou Zheng Wang Xiufeng Liu Qing Xie Weidong Jia Ming Zhao Xinyu Bi Gong Li Xueli Bai Yuan Ji Li Xu Xiao-Dong Zhu Dousheng Bai Yajin Chen Yongjun Chen Chaoliu Dai Rongping Guo Wenzhi Guo Chunyi Hao Tao Huang Zhiyong Huang Deyu Li Gang Li Tao Li Xiangcheng Li Guangming Li Xiao Liang Jingfeng Liu Fubao Liu Shichun Lu Zheng Lu Weifu Lv Yilei Mao Guoliang Shao Yinghong Shi Tianqiang Song Guang Tan Yunqiang Tang Kaishan Tao Chidan Wan Guangyi Wang Lu Wang Shunxiang Wang Tianfu Wen Baocai Xing Bangde Xiang Sheng Yan Dinghua Yang Guowen Yin Tao Yin Zhenyu Yin Zhengping Yu Bixiang Zhang Jialin Zhang Shuijun Zhang Ti Zhang Yamin Zhang Yubao Zhang Aibin Zhang Haitao Zhao Ledu Zhou Wu Zhang Zhenyu Zhu Shukui Qin Feng Shen Xiujun Cai Gaojun Teng Jianqiang Cai Minshan Chen Qiang Li Lianxin Liu Weilin Wang Tingbo Liang Jiahong Dong Xiaoping Chen Xuehao Wang Shusen Zheng Jia Fan 无 | 2022 | Hepatobiliary Surgery and Nutrition2022，11，2： | 4 |
| 11 | Generation of tooth-like structures from integration-free human urine induced pluripotent stem cells显示文摘Background:Tooth is vital not only for a good smile,but also good health.Yet,we lose tooth regularly due to accidents or diseases.An ideal solution to this problem is to regenerate tooth with patients’own cells.Here we describe the generation of tooth-like structures from integration-free human urine induced pluripotent stem cells(ifhU-iPSCs).Results:We first differentiated ifhU-iPSCs to epithelial sheets,which were then recombined with E14.5 mouse dental mesenchymes.Tooth-like structures were recovered from these recombinants in 3 weeks with success rate up to 30%for 8 different iPSC lines,comparable to H1 hESC.We further detected that ifhU-iPSC derived epithelial sheets differentiated into enamel-secreting ameloblasts in the tooth-like structures,possessing physical properties such as elastic modulus and hardness found in the regular human tooth.Conclusion:Our results demonstrate that ifhU-iPSCs can be used to regenerate patient specific dental tissues or even tooth for further drug screening or regenerative therapies. | Jinglei Cai Yanmei Zhang Pengfei Liu Shubin Chen Xuan Wu Yuhua Sun Ang Li Ke Huang Rongping Luo Lihui Wang Ying Liu Ting Zhou Shicheng Wei Guangjin Pan Duanqing Pei | 2013 | Cell Regeneration2013，2，1： | 4 |

| 14 | MPTP Induces Systemic Parkinsonism in Middle-Aged Cynomolgus Monkeys:Clinical Evolution and Outcomes显示文摘In this study,we developed a systemic PD model in middle-aged cynomolgus monkeys using individualized low-dose MPTP,to explore effective indicators for the early prediction of clinical outcomes.MPTP was not stopped until the animals showed typical PD motor symptoms on days 10 to 13 after MPTP administration when the Kurlan score reached 10;this abrogated the differences in individual susceptibility to MPTP.The clinical symptoms persisted,peaking on days 3 to 12 after MPTP withdrawal(rapid progress stage),and then the Kurlan score plateaued.A Kurlan score at the end of the rapid progress stage >15 reflected stable or slowly-progressive PD,while a score <15 indicated spontaneous recovery.The entire clinical evolution and outcome of the systemic PD model was characterized in this study,thus providing options for therapeutic and translational research. | Feng Yue Sien Zeng Rongping Tang Guoxian Tao Piu Chan | 2017 | Neuroscience Bulletin2017，33，1： | 3 |

| 16 | Effect of Colored Sticky Cards on Non-target Insects显示文摘Field experiments to evaluate four different colored sticky cards for trapping non-target insects were conducted in an organic maize field in the Heinigou region of China. Yellow, blue, green, and red sticky cards were used to trap insects in the field. The total number of insects species caught was 54, with 3,862 individuals recorded. Over half of the specimens caught were non-target insects, including phytophagous insects, particularly dipteran species(including many mosquitoes)(50.3%), followed by target pests(37.0%), and beneficial insects(12.7%). Statistical analysis revealed a significant difference in attraction to target pests, non-target pests, and beneficial insects among treatment groups. The results showed that higher numbers of target pests(Myzus persicae Sulzer, Empoasca flavescens Fabricius, Nysius ericaecshinly Schilling) were caught on yellow sticky card traps compared with blue, green, or red sticky card traps, indicating that yellow was the best trap color for target pests, with green and blue being progressively less attractive. For non-target insects, including phytophagous insects, flies, and mosquitoes,higher numbers of were caught on blue sticky card traps compared with yellow,green, or red sticky card traps. Our study indicated that blue was the most attractive color for flies, especially for the housefly, Musca domestica Linnaeus. Our study also showed that most beneficial insects exhibited preferences to particular trap color characteristics: yellow was the most attractive color for parasitic wasps and lady beetles; blue was the most attractive color for hoverflies and honeybees. In contrast,green and red had no significant attraction to beneficial insects. | Zhen CHEN Yihang GE Xia LIU Rongping KUANG | 2015 | Agricultural Science & Technology2015，16，5： | 2 |
| 17 | Transarterial infusion chemotherapy with FOLFOX for advanced hepatocellular carcinoma:a multi-center propensity score matched analysis of real-world practice显示文摘Background:To compare the treatment effectiveness and safety among transarterial infusion chemotherapy(TAI)with FOLFOX regimen,transarterial chemoembolization(TACE),and sorafenib in patients with BCLC stage C hepatocellular carcinoma(HCC).Methods:The data of consecutive patients with BCLC stage C HCC treated with TAI,TACE,or sorafenib from January 2015 to December 2018 at three centers were retrospectively analyzed.Propensity-score matched(PSM)analysis was pairwise performed to reduce selection bias.Treatment effectiveness and safety were evaluated and compared using the Kaplan-Meier method,log-rank test,Cox regression models,andχ2 test.Results:The median overall survival(OS)in the matched TAI cohort was significantly longer than the sorafenib cohort(19.6 vs.7.5 months,P=0.009),and the TACE cohort(estimated 27.8 vs.6.6 months,P<0.001).The difference in median progression-free survival(PFS)between the matched TAI and sorafenib cohorts was not significant(5.8 vs.2.3 months,P=0.219).The median PFS in the matched TAI cohort was significantly longer than the TACE cohort(6.5 vs.2.8 months,P<0.001).The objective response rate(ORR)in the matched TAI cohort was significantly higher than the sorafenib cohort(36.4%vs.0.0%,P<0.001)and the TACE cohort(48.7%vs.4.7%,P<0.001).The incidences of adverse events(AEs)were similar among these three cohorts.Conclusions:TAI with FOLFOX regimen was an effective and safe therapy that improved survival of patients with BCLC stage C HCC. | Shaohua Li Jie Mei Qiaoxuan Wang Feng Shi Hongyan Liu Ming Zhao Lianghe Lu Yihong Ling Zhixing Guo Yabing Guo Xiaoming Chen Ming Shi Wan Yee Lau Wei Wei Rongping Guo | 2021 | Hepatobiliary Surgery and Nutrition2021，10，5： | 2 |

| 20 | Effects of Low Temperature Stress on Seedling Growth of Plateau Japonica Rice显示文摘[Objective] The study aimed to screen rational seedling raising date and seedling raising mode for plateau japonica rice,in order to reduce the effect of low temperature on seedlings. [Method]The seedlings of conventional japonica rice Hexi 22-2 and giant embryo No. 1 japonica rice were treated at day temperature 12℃ / night temperature 8℃ and day temperature 14 ℃ / night temperature 10 ℃,and the indicators including chlorophyll content,soluble sugar content,soluble protein content,survival rate,plant height,number of ≥ 1 cm roots,leaf wilting degree and aboveground dry matter weight were determined after treated for0,3 and 6 d,respectively. [Result]Chlorophyll content of seedlings decreased when treated by low temperature for a certain period; with the prolongation of treatment time,contents of soluble sugar and soluble protein in some low temperature treatments increased,while plant height,number of ≥ 1 cm roots and aboveground dry matter weight increased slowly,but the growth rate was significantly lower than that at room temperature; with the decrease of temperature and the prolongation of treatment time,leaf wilting degree increased. The comprehensive experimental results showed that with the increasing duration of low temperature,when two japonica rice varieties grew under the same low temperature,seedlings grew more and more slowly,probably because the lower the treatment temperature,the greater the damage on plants. Giant Embryo No. 1 had weaker cold tolerance than Hexi 22-2. [Conclusion]The study provides a theoretical basis for formulation of seedling raising technique of plateau japonica rice. | Dai Hongyan Hua Jinsong Zhang Rongping Cai Guangze Chen Liquan | 2015 | Plant Diseases and Pests2015，6，3： | 1 |
