| 1 | Activation of gibberellin 2-oxidase 6 decreases active gibberellin levels and creates a dominant semi-dwarf phenotype in rice (Oryza sativa L.)显示文摘Gibberellin (GA) 2-oxidase plays a key role in the GA catabolic pathway through 2β-hydroxylation.In the present study,we isolated a CaMV 35S-enhancer activation tagged mutant,H032.This mutant exhibited a dominant dwarf and GA-deficient phenotype,with a final stature that was less than half of its wild-type counterpart.The endogenous bioactive GAs are markedly decreased in the H032 mutant,and application of bioactive GAs (GA3 or GA4) can reverse the dwarf phenotype.The integrated T-DNA was detected 12.8 kb upstream of the OsGA2ox6 in the H032 genome by TAIL-PCR.An increased level of OsGA2ox6 mRNA was detected at a high level in the H032 mutant,which might be due to the enhancer role of the CaMV 35S promoter.RNAi and ectopic expression analysis of OsGA2ox6 indicated that the dwarf trait and the decreased levels of bioactive GAs in the H032 mutant were a result of the up-regulation of the OsGA2ox6 gene.BLASTP analysis revealed that OsGA2ox6 belongs to the class III of GA 2-oxidases,which is a novel type of GA2ox that uses C20-GAs (GA12 and/or GA53) as the substrates.Interestingly,we found that a GA biosynthesis inhibitor,paclobutrazol,positively regulated the OsGA2ox6 gene.Unlike the over-expression of OsGA2ox1,which led to a high rate of seed abortion,the H032 mutant retained normal flowering and seed production.These results indicate that OsGA2ox6 mainly affects plant stature,and the dominant dwarf trait of the H032 mutant can be used as an efficient dwarf resource in rice breeding. | Jian Huang Ding Tang Yi Shen Baoxiang Qin Lilan Hong Aiqing You Ming Li Xin Wang Hengxiu Yu Minghong Gu Zhukuan Cheng | 2010 | Journal of Genetics and Genomics2010,37,1: | 36 |

| 6 | Mycoplasma infections and different human carcinomas显示文摘AIM To explore relationships between human carcinomas and mycoplasma infection.METHODS Monoclonal antibody PD4, which specifically recognizes a distinct protein from mycoplasma hyorhinis, was used to detect mycoplasma infection in different paraffinembedded carcinoma tissues with immunohistochemistry. PCR was applied to amplify the mycoplasma DNA from the positive samples for confirming immunohistochemistry.RESULTS Fifty of 90 cases (56%) of gastric carcinoma were positive for mycoplasma hyorhinis. In other gastric diseases, the mycoplasma infection ratio was 28% (18/49) in chronic superficial gastritis, 30% (14/ 46) in gastric ulcer and 37% (18/ 49) in intestinal metaplasia. The difference is significant with gastric cancer (X2=12.06, P<0.05). In colon carcinoma, the mycoplasma infection ratio was 55.1% (32/58), but it was 20.9% (10/49) in adenomarous polyp (X2=13.46, P<0.005).Gastric and colon cancers with high differentiation had a higher mycoplasma infection ratio than those with low differentiation (P< 0.05). Mycoplasma infection in esophageal cancer, lung cancer, breast cancer and glioma was 50.9% (27/53), 52.6% (31/ 59), 39.7%(25/63) and 41% (38/91), respectively. The mycoplasma DNA was successfully amplified with the DNA extracted from the cancer tissues that were positive for mycoplasma infection (detected with antibody PD4).CONCLUSION There was high correlation between mycoplasma infection and different cancers, which suggests the possibility of an association between the two. The mechanism involved in oncogenesis by mycoplasma remains unknown. | Su Huang Ji You Li Jan Wu Lin Meng Cheng Chao Shou Beijing Institute for Cancer Research, Peking University School of Oncology, Beijing 100034.

| 10 | Protective Effect of Resveratrol on the Brain in a Rat Model of Epilepsy显示文摘Accumulating evidence has suggested resveratrol as a promising drug candidate for the treatment of epilepsy. To validate this, we tested the protective effect of resveratrol on a kainic acid(KA)-induced epilepsy model in rats and investigated the underlying mechanism. We found that acute resveratrol application partially inhibited evoked epileptiform discharges in the hippocampal CA1 region. During acute, silent and chronic phases of epilepsy,the expression of hippocampal kainate glutamate receptor(GluK2) and the GABAAreceptor alpha1 subunit(GABAAR-alpha1) was up-regulated and down-regulated,respectively. Resveratrol reversed these effects and induced an antiepileptic effect. Furthermore, in the chronic phase, resveratrol treatment inhibited the KA-induced increased glutamate/GABA ratio in the hippocampus. The antiepileptic effects of resveratrol may be partially attributed to the reduction of glutamate-induced excitotoxicity and the enhancement in GABAergic inhibition. | Zhen Li Zhuyan You Min Li Liang Pang Juan Cheng Liecheng Wang | 2017 | Neuroscience Bulletin2017,33,3: | 11 |
| 11 | Oxidative Stress before and after Operation in Patients with Chronic Cholecystitis Containing Gallstone显示文摘To study the relationship of oxidative, antioxidative constituents and antioxidases in blood with chronic cholecystitis containing gallstone, levels of lipoperoxides (LPO), nitric oxide (NO), vitamin C(VC), vitamin E (VE) and β carotene (β CAR) in plasma as well as level of LPO, activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH Px) in erythrocytes were investigated by spectrophotometric assay in 107 patients with this condition (PCg) and 100 healthy volunteers (HVs). Compared with HVs group, the average value of LPO and NO in plasma and that of LPO in erythrocytes of PCg group were significantly increased ( P <0.0001), while that of VC, VE and β CAR in plasma and the average activities of SOD, CAT and GSH Px in erythrocytes were significantly decreased ( P <0.0001). Linear regression and correlation analysis for 107 preoperative PCg showed that the value of LPO and NO in plasma and that of LPO in erythrocytes of PCg gradually increased ( P <0.0001), representing a significant linear positive correlation. The value of VC, VE and β CAR in plasma and that of SOD, CAT and GSH Px in erythrocytes of PCg gradually decreased ( P <0.0001), representing a significant linear negative correlation. Stepwise regression and correlation analysis for 107 preoperative PCg suggested that the closest correlation was observed between the course of disease and the value of NO and VC in plasma and that of SOD, GSH Px and LPO in erythrocytes, r =0.7306, F =32.1408, P <0.0001. Compared with the preoperative PCg group, the average value of LPO and NO in plasma and that of LPO in erythrocytes of the postoperative PCg group were significantly decreased ( P <0.0001). Furthermore, the average value of VC in plasma and that of SOD, CAT and GSH Px in erythrocytes of the postoperative PCg group were significantly increased ( P <0.0001), whereas no significant difference was found between their average value of VE and β CAR in plasma. These findings suggested that oxidative stress was an aggravating pathological condition in PCg group. Therefore, we recommend that in treating PCg, antioxidants such as VC, VE, β CAR should be given in order to alleviate their potential oxidative damages. | ZHOU JUN FU , CHEN PENG , YANG JIN LU +, ZHU YOU GEN + PENG CHENG HONG , AND WU YU LIAN The 2nd Affiliated Hospital, Medical College of Zhejiang University, 88 Jiefang Road, Hangzhou, 310009, Zhejian | 2000 | Biomedical and Environmental Sciences2000,13,4: | 10 |

| 14 | Oral microbiota in human systematic diseases显示文摘Oral bacteria directly affect the disease status of dental caries and periodontal diseases. The dynamic oral microbiota cooperates with the host to reflect the information and status of immunity and metabolism through two-way communication along the oral cavity and the systemic organs. The oral cavity is one of the most important interaction windows between the human body and the environment.The microenvironment at different sites in the oral cavity has different microbial compositions and is regulated by complex signaling,hosts, and external environmental factors. These processes may affect or reflect human health because certain health states seem to be related to the composition of oral bacteria, and the destruction of the microbial community is related to systemic diseases. In this review, we discussed emerging and exciting evidence of complex and important connections between the oral microbes and multiple human systemic diseases, and the possible contribution of the oral microorganisms to systemic diseases. This review aims to enhance the interest to oral microbes on the whole human body, and also improve clinician’s understanding of the role of oral microbes in systemic diseases. Microbial research in dentistry potentially enhances our knowledge of the pathogenic mechanisms of oral diseases,and at the same time, continuous advances in this frontier field may lead to a tangible impact on human health. | Xian Peng Lei Cheng Yong You Chengwei Tang Biao Ren Yuqing Li Xin Xu Xuedong Zhou | 2022 | International Journal of Oral Science2022,14,1: | 9 |
| 15 | Rainfall and Tillage Impacts on Soil Erosion of Sloping Cropland with Subtropical Monsoon Climate- A Case Study in Hilly Purple Soil area, China显示文摘Under global warming, storm events tend to intensify, particularly in monsoon-affected regions.As an important agricultural area in China, the purple soil region in the Sichuan Basin, where it has a prevailing monsoon climate, is threatened by serious soil erosion. Tillage operations alter runoff and soil erosion processes on croplands by changing the physical properties of the soil surface. To clarify the relationship between tillage and soil erosion in the purple soil region, three different tillage practices in this region were investigated at the plot scale over 4 years: bare land with minimum tillage(BL),conventional tillage(CT) and seasonal no-tillage ridges(SNTR) which was initially designed to prevent soil erosion by contoured ridges and no-tillage techniques. The results showed that although there were no significant differences in the surface runoff and soil erosion among the three practices, BL causedrelatively high surface runoff and soil erosion,followed by CT and SNTR. Classification and comparison of the rainfall events based on cluster analysis(CA) verified that the surface runoff was not significantly different between most intensive event and long intensive events but was significantly different between most intensive and short and medium-duration events. Only the rainfall events with the highest rainfall intensity could trigger serious soil erosion, up to 1000 kg ha-1 in the region. Further detailed investigations on the effects of tillage operations on the soil erosion in a subtropical region with a monsoon climate are needed to provide a basis for modeling catchments and designing better management practices. | TANG Jia-liang CHENG Xun-qiang ZHU Bo GAO Mei-rong WANG Tao ZHANG Xi-feng ZHAO Pei YOU Xiang | 2015 | Journal of Mountain Science2015,12,1: | 9 |
| 16 | Progress in ceramic materials and structure design toward advanced thermal barrier coatings显示文摘Thermal barrier coatings(TBCs)can effectively protect the alloy substrate of hot components in aeroengines or land-based gas turbines by the thermal insulation and corrosion/erosion resistance of the ceramic top coat.However,the continuous pursuit of a higher operating temperature leads to degradation,delamination,and premature failure of the top coat.Both new ceramic materials and new coating structures must be developed to meet the demand for future advanced TBC systems.In this paper,the latest progress of some new ceramic materials is first reviewed.Then,a comprehensive spalling mechanism of the ceramic top coat is summarized to understand the dependence of lifetime on various factors such as oxidation scale growth,ceramic sintering,erosion,and calcium–magnesium–aluminium–silicate(CMAS)molten salt corrosion.Finally,new structural design methods for high-performance TBCs are discussed from the perspectives of lamellar,columnar,and nanostructure inclusions.The latest developments of ceramic top coat will be presented in terms of material selection,structural design,and failure mechanism,and the comprehensive guidance will be provided for the development of next-generation advanced TBCs with higher temperature resistance,better thermal insulation,and longer lifetime. | Zhi-Yuan WEI Guo-Hui MENG Lin CHEN Guang-Rong LI Mei-Jun LIU Wei-Xu ZHANG Li-Na ZHAO Qiang ZHANG Xiao-Dong ZHANG Chun-Lei WAN Zhi-Xue QU Lin CHEN Jing FENG Ling LIU Hui DONG Ze-Bin BAO Xiao-Feng ZHAO Xiao-Feng ZHANG Lei GUO Liang WANG Bo CHENG Wei-Wei ZHANG Peng-Yun XU Guan-Jun YANG Hong-Neng CAI Hong CUI You WANG Fu-Xing YE Zhuang MA Wei PAN Min LIU Ke-Song ZHOU Chang-Jiu LI | 2022 | Journal of Advanced Ceramics2022,11,7: | 9 |
| 17 | Preparation of highly conductive graphene-coated glass fibers by sol-gel and dip-coating method显示文摘In order to fabricate highly-conductive glass fibers using graphene as multi-functional coatings, we reported the preparation of graphene-coated glass fibers with high electrical conductivity through solgel and dip-coating technique in a simple way. Graphene oxide (GO) was partially reduced to graphene hydrosol, and then glass fibers were dipped and coated with the reduced GO (rGO). After repeated solgel and dip-coating treatment, the glass fibers were fully covered with rGO coatings, and consequently exhibited increased hydrophobicity and high electrical conductivity. The graphene-coated fibers exhibited good electrical conductivity of 24.9 S/cm, being higher than that of other nanocarbon-coated fibers and commercial carbon fibers, which is mainly attributed to the high intrinsic electrical conductivity of rGO and full coverage of fiber surfaces. The wettability and electrical conductivity of the coated fibers strongly depended on the dip-coating times and coating thickness, which is closely associated with coverage degree and compact structure of the graphene coatings. By virtue of high conductivity and easy operation, the graphene-coated glass fibers have great potential to be used as flexible conductive wires, highly-sensitive sensors, and multi-functional fibers in many fields. | Minghe Fang Xuhai Xiong Yabin Hao Tengxin Zhang Han Wang Hui-Ming Cheng You Zeng | 2019 | Journal of Materials Science & Technology2019,35,9: | 8 |
| 18 | Effects of electroacupuncture at Guanyuan(CV 4)or Sanyinjiao(SP 6)on hypothalamus-pituitary-ovary axis and spatial learning and memory in female SAMP8 mice显示文摘OBJECTIVE: To investigate the effects of electroacupuncture(EA) at the Guanyuan(CV 4) or Sanyinjiao(SP 6) acupoints on the hypothalamus-pituitary-ovary(HPO) axis and spatial learning and memory in female mice.METHODS: Nine-month-old female mice with senescence-accelerated mouse prone 8(SAMP8)were divided into three groups: the disease model,EA-Guanyuan and EA-Sanyinjiao groups. Concurrently, 9-month old female mice with senescence-accelerated mouse resistance 1(SAMR1)were set as the control model group. The two treatment groups were given the same pattern of EA stimulation. Gonadotropin-releasing hormone, luteinizing hormone, follicle-stimulating hormone(FSH) and Serum estradiol levels in the Hypothalamus-pituitary-ovary axis were assessed by enzyme-linked immunosorbent assay to determinethe HPO axis function level. Spatial learning and memory were assessed by the Morris Water Maze(MWM) test.RESULTS:(a) HPO axis: compared with the control model group, the disease model group displayed a decrease in E2 levels(P < 0.01), and an increase in Gn RH, LH and FSH levels(P < 0.01). E2 levels were increased in EA treatment groups compared with the disease model group(P < 0.05). In contrast,Gn RH and LH and FSH levels were reduced(P <0.05). EA-Sanyinjiao group was superior than EA-Guanyuan group on increasing E2 and declining Gn RH levels(P < 0.01).(b) The MWM test demonstrated that the response latency in the EA-Sanyinjiao treatment group declined from day 2 to day5 compared with the disease model group(P <0.05), whereas the EA-Guanyuan treatment group showed no significant difference.CONCLUSION: EA can regulate hormone(E2, FSH,LH, Gn RH) levels in the HPO axis and the spatial learning and memory ability in female SAMP8 mice. Moreover, this effect may have been more pronounced in the EA-Sanyinjiao group than the EA-Guanyuan group. The underlying mechanism of the EA-induced changes may be related to gonadal hormone shifts in the HPO axis, followed by an improvement in spatial learning and memory. | Wang Jing Cheng Kai Qin Zhuo Wang Yanping Zhai Lijing You Min Wu Juanjiao | 2017 | Journal of Traditional Chinese Medicine2017,37,1: | 8 |
| 19 | Efficacy of thymosin alpha-1 and interferon alpha in treatment of chronic viral hepatitis B:A randomized controlled study显示文摘AIM: To observe the efficiency and safety of thymosin-α1 treatment in patients with hepatitis B e antigen (HBeAg) and HBV DNA positive chronic hepatitis. METHODS: Sixty-two patients were randomly divided into groups A and B. The patients in group A received subcutaneous injection of 1.6 mg thymosin-α1, twice a week (T-α1 group) for six months, and the patients in group B received 5 MU interferon alpha (IFN-α) each day for fifteen days, then three times weekly (IFN-α group) for six months. The results between two groups treated with and the group untreated with IFN-α which was followed up for 12 mo (historical control group consisting of 30 patients) were compared, and three groups were comparable between each other (P > 0.05) at baseline (age, sex, clinical history, biochemical, and serological parameters). RESULTS: At the end of treatment, complete response, which was defined as alanine aminotransferase (ALT) normalization and HBV DNA and HBeAg loss, occurred in 9 of 29 (31.0%) patients in the T-α1 group and in 15 of 33 (45.5%) patients in the IFN-α group (c2 = 1.36, P >0.05). After a follow-up period of six months, a complete response was observed in 14 of 29 (48.3%) patients in the T-α1 group and in 9 of 33 (27.3%) patients in the IFN-α group (c2 = 2.93, P > 0.05). Compared with the results observed in the historical control (HC) group untreated with IFN-α which was followed up for 12 mo, the rate of complete response was significantly higher in IFN-α group at the end of therapy (1 of 30 vs 15 of 33, c2 = 14.72, P < 0.001) and in the T-α1 group at the end of follow-up (1 of 30 vs 14 of 29, c2 = 15.71, P < 0.001). In T-α1 and IFN-α treatment groups, the area under (the plasma concentration time) curve (AUC) of negative HBV DNA and HBeAg was 34%, 17%, 31% and 19% smaller than that in the HC group. By the end of the follow- up period, the proportions of ALT normalization and negative HBV DNA in the T-α1 group were significantly higher than those in the IFN-α and HC groups. The odds of ALT normalization and negative HBV DNA at the end of the follow-up was three-fold higher in the T-α1 group than in the IFN-α group. Unlike IFN-α, T-α1 was well tolerated by all patients, and no side effects appeared in T-α1 group.CONCLUSION: The results suggest that a 6-mo course of T-α1 therapy is effective and safe in patients with chronic hepatitis B. T-α1 is able to reduce HBV replication in patients with chronic hepatitis B. Furthermore, T-α1 is better tolerated than IFN-α and can gradually induce more sustained ALT normalization and HBV DNA and HBeAg loss. However, a response rate of 48.3% is still less ideal. A more effective therapeutic approach warrants further study. | Jing You Lin Zhuang Hong-Ying Cheng Shou-Ming Yan Lan Yu Jun-Hua Huang Bao-Zhang Tang Meng-Ling Huang Yong-Liang Ma Virasakdi Chongsuvivatwong Hutcha Sriplung Alan Geater Yan-Wei Qiao Rong-Xue Wu | 2006 | World Journal of Gastroenterology2006,12,41: | 8 |
