| 1 | Effects of mixture ratio on anaerobic co-digestion with fruit and vegetable waste and food waste of China显示文摘The biochemical methane potentials for typical fruit and vegetable waste (FVW) and food waste (FW) from a northern China city were investigated,which were 0.30,0.56 m 3 CH 4/kgVS (volatile solids) with biodegradabilities of 59.3% and 83.6%,respectively.Individual anaerobic digestion testes of FVW and FW were conducted at the organic loading rate (OLR) of 3 kg VS/(m 3 ·day) using a lab-scale continuous stirred-tank reactor at 35℃.FVW could be digested stably with the biogas production rate of 2.17 m 3/(m 3 ·day) and methane production yield of 0.42 m 3 CH 4/kg VS.However,anaerobic digestion process for FW was failed due to acids accumulation.The effects of FVW:FW ratio on co-digestion stability and performance were further investigated at the same OLR.At FVW and FW mixing ratios of 2:1 and 1:1,the performance and operation of the digester were maintained stable,with no accumulation of volatile fatty acids (VFA) and ammonia.Changing the feed to a higher FW content in a ratio of FVW to FW 1:2,resulted in an increase in VFAs concentration to 1100-1200mg/L,and the methanogenesis was slightly inhibited.At the optimum mixture ratio 1:1 for co-digestion of FVW with FW,the methane production yield was 0.49 m 3 CH 4/kg VS,and the volatile solids and soluble chemical oxygen demand (sCOD) removal efficiencies were 74.9% and 96.1%,respectively. | Jia Lin Jiane Zuo Lili Gan Peng Li Fenglin Liu Kaijun Wang Lei Chen Hainan Gan | 2011 | Journal of Environmental Sciences2011，23，8： | 36 |
| 2 | Starch/polyvinyl alcohol blended materials used as solid carbon source for tertiary denitrification of secondary efuent显示文摘Starch/polyvinyl alcohol(PVA) blended materials for using as a solid carbon source(SCS) were prepared by blending PVA and gelatinized starch in an aqueous solution system, in which PVA served as framework material and starch as carbon source. The optimization of starch content and temperature efects were investigated. It was indicated that higher denitrification efciency could be achieved with more starch in the materials. The average specific denitrification rates were 0.93, 0.66, 0.37 and 0.36 mg/(g·day)corresponding to starch content of 70%, 60%, 40% and 30% respectively at 37°C. The denitrification rates increased when operating temperature was raised from 23°C to 30°C and then 37°C. The mechanism of carbon release was analyzed incorporating the experimental results of abiotic release in deionized water. The organic carbon was mainly hydrolyzed by microbes, and the biological release efciencies were at the range of 89.2% to 96.0%. A long-term experiment with a continuous flow reactor with SCS material containing 70% starch was conducted to gain some experience for practical application. When the influent nitrate concentration was in the range of 35.2 to 39.1 mg/L, hydraulic retention time of 4 hr, and operating temperature of 30°C, a nitrogen removal efciency up to94.6% and denitrification rate of 0.217 kg/(m3·day) was achieved. The starch-based materials developed in this study can be used as a solid carbon source for tertiary nitrogen removal from secondary efuent. | Peng Li Jiane Zuo Wei Xing Lei Tang Xiangyang Ye Zaixing Li Lin Yuan Kaijun Wang Hongtao Zhang | 2013 | Journal of Environmental Sciences2013，25，10： | 11 |
| 3 | Methanogenic community dynamics in anaerobic co-digestion of fruit and vegetable waste and food waste显示文摘A lab-scale continuously-stirred tank reactor (CSTR), used for anaerobic co-digestion of fruit and vegetable waste (FVW) and food waste (FW) at different mixture ratios, was operated for 178 days at the organic loading rate of 3 kg VS (volatile solids)/(m3·day). The dynamics of the Archaeal community and the correlations between environmental variables and methanogenic community structure were analyzed by polymerase chain reactions-denaturing gradient gel electrophoresis (PCR-DGGE) and redundancy analysis (RDA), respectively. PCR-DGGE results demonstrated that the mixture ratio of FVW to FW altered the community composition of Archaea. As the FVW/FW ratio increased, Methanoculleus, Methanosaeta and Methanosarcina became the predominant methanogens in the community. Redundancy analysis results indicated that the shift of the methanogenic community was significantly correlated with the composition of acidogenic products and methane production yield. Different mixture ratios of substrates led to different compositions of intermediate metabolites, which may affect the methanogenic community. These results suggested that the analysis of microbial communities could be used to diagnose anaerobic processes. | Jia Lin Jiane Zuo Ruofan Ji Xiaojie Chen Fenglin Liu Kaijun Wang Yunfeng Yang | 2012 | Journal of Environmental Sciences2012，24，7： | 4 |
| 4 | Autonomous navigation method and technology implementation of high-precision solar spectral velocity measurement显示文摘The velocity information of spacecraft can be directly obtained by the autonomous navigation method based on astronomical spectral velocity measurement. It provides complete direct velocity measurement information for the traditional navigation methods represented by astronomical angle measurement and astronomical ranging, which is of great significance for spacecraft high precision autonomous navigation. This paper comprehensively introduces the principle and navigation method of astronomical spectral velocity measurement, as well as the technical realization of the solar atomic frequency discriminator for autonomous navigation(SAFDAN) based on atomic frequency discrimination velocity measurement. The new SAFDAN is the first instrument to measure the Doppler velocity of spacecraft relative to the Sun. Carried by the CHASE mission, the in-orbit experiment of the SAFDAN is realized, and the in-orbit velocity measurement accuracy reaches 1.93 m/s, which effectively verifies the feasibility of the astronomical spectral velocity measurement method and technology. | Wei Zhang Yong Yang Wei You JinZhou Zheng Hui Ye KaiJun Ji Xiao Chen Xin Lin QingLong Huang XueWu Cheng Wei Zhang FaQuan Li | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 3 |

| 6 | Early application of nerve growth factor affects serum inflammatory cytokine levels in neonatal hypoxic ischemic encephalopathy显示文摘BACKGROUND: It has been demonstrated that there are changes of various cytokines, chemokines and adhesion factors in neonatal hypoxic ischemic encephalopathy (HIE). What are the changes of interleukin-6 and interleukin-18 in serum of HIE neonates. OBJECTIVE: To observe the dynamic changes of interleukin-6 and interleukin-18 in peripheral serum at different time after HIE in neonates, and analyze the possible therapeutic efficacy of early application of NGF. DESIGN: A non-randomized controlled observation synchronically. SETTING: Department of Neonatology, Sun Yat-sen Hospital affiliated to Sun Yat-sen University. PARTICIPANTS: Sixty neonates with HIE were selected from the Department of Neonatology, Sun Yat-sen Hospital affiliated to Sun Yat-sen University from January 2004 to October 2006, including 32 boys and 28 girls, who were all accorded with the diagnostic standards for moderate to severe HIE. The neonates were divided into two groups NGF-treated group (n =30), HIE group (n =30). The HIE neonates in the NGF-treated group were given routine treatment and intramuscular injection of NGF within 24 hours after birth. Those in the HIE group were given routine treatments. Meanwhile, 30 apneic normal neonates (17 boys and 13 girls) at the same period were selected as the control group. The gestational age was 37–42 weeks in all the three groups, the body mass at birth was 2 500–4 000 g. Informed contents were obtained from the relatives of all the enrolled neonates. METHODS: The HIE neonates in the NGF-treated group were given routine treatment and intramuscular injection of NGF (2 000 U) within 24 hours after birth, once a day, 10 days as a course. Those in the HIE group were given routine treatments. Blood samples (3 mL) were drawn from femoral vein in all the neonates 1, 3 and 7 days after birth. The levels of interleukin-6 and interleukin-18 in serum were detected with enzyme-linked immunoabsorbent assay (ELISA). MAIN OUTCOME MEASURES: Serum levels of interleukin-6 and interleukin-18 at 1, 3 and 7 days after birth. RESULTS: All the 60 HIE neonates and 30 normal neonates were involved in the final analysis of results. ① Serum level of interleukin-6: The serum levels of interleukin-6 at 1, 3 and 7 days after birth in the HIE group were all lower than those in the control group (P < 0.05), and gradually recovered to the normal level as time prolonged. The serum levels of interleukin-6 at 1, 3 and 7 days after birth in the NGF-treated group were higher than those in the HIE group (P < 0.05). ②Serum level of interleukin-18: The serum levels of interleukin-18 at 1, 3 and 7 days after birth in the HIE group were all higher than those in the control group (P < 0.05), especially that at 3 days. The serum levels of interleukin-18 at 1, 3 and 7 days after birth in the NGF-treated group were lower than those in the HIE group (P < 0.05). CONCLUSION: After hypoxic ischemia, the level of interleukin-6 was decreased and that of interleukin-18 was increased in peripheral serum in HIE neonates, while NGF could balance the levels of interleukin-6 and interleukin-18, adjust the immunological function, and protect the nerve cells. | Jingguo Chen Huijuan Huang Kaijun Zheng Ronghua Xia Jian Chen Xiufang Yang Chunhua Ye Qiang Lin | 2007 | Neural Regeneration Research2007，2，7： | 1 |
| 7 | Mutations of Desmoglein‑2 in Sudden Unexplained Death in the Chinese Han Population显示文摘Sudden unexplained death(SUD)remains a puzzle in forensic medicine.Desmoglein‑2(DSG2)has been linked to arrhythmogenic right ventricular cardiomyopathy which may cause life‑threatening ventricular arrhythmias and sudden death.Fatal arrhythmias resulting in sudden death also occur in the absence of morphologic cardiac abnormalities at autopsy.We hypothesized that DSG2 mutations may be responsible for certain Chinese SUD cases.We sequenced all 15 exons of DSG2 in DNA extracted from postmortem heart tissues of 25 Chinese patients dying from SUD.The primers were designed using the Primer Express 3.0 software.Direct sequencing for both sense and antisense strands was performed with a BigDye Terminator DNA sequencing kit on a 3130 Xl Genetic Analyzer.Mutation damage prediction was made using Mutation Taster,PolyPhen,and SIFT software.In 2 of 25 cases of Chinese SUD samples,two DSG2 heterozygous mutations(p.P927 L and p.T1070M)were identified,and one is probably damaging.We concluded that DSG2 mutations may be related to the occurrence of part of SUD cases in the Chinese Han population. | Junyi Lin Yulei Yang Ziqin Zhao Yiwen Shen Kaijun Ma Mingchang Zhang | 2019 | Journal of Forensic Science and Medicine2019，5，2： | 0 |
| 8 | Mechanical stretching boosts expansion and regeneration of intestinal organoids through fueling stem cell self-renewal显示文摘Intestinal organoids,derived from intestinal stem cell self-organization,recapitulate the tissue structures and behav-iors of the intestinal epithelium,which hold great potential for the study of developmental biology,disease modeling,and regenerative medicine.The intestinal epithelium is exposed to dynamic mechanical forces which exert profound effects on gut development.However,the conventional intestinal organoid culture system neglects the key role of mechanical microenvironments but relies solely on biological factors.Here,we show that adding cyclic stretch to intestinal organoid cultures remarkably up-regulates the signature gene expression and proliferation of intestinal stem cells.Furthermore,mechanical stretching stimulates the expansion of SOX9+progenitors by activating the Wnt/β-Catenin signaling.These data demonstrate that the incorporation of mechanical stretch boosts the stemness of intestinal stem cells,thus benefiting organoid growth.Our findings have provided a way to optimize an organoid generation system through understanding cross-talk between biological and mechanical factors,paving the way for the application of mechanical forces in organoid-based models. | Fanlu Meng Congcong Shen Li Yang Chao Ni Jianyong Huang Kaijun Lin Zanxia Cao Shicai Xu Wanling Cui Xiaoxin Wang Bailing Zhou Chunyang Xiong Jihua Wang Bing Zhao | 2022 | Cell Regeneration2022，11，1： | 0 |
| 9 | Sound insulation performance of plates with interconnected distributed piezoelectric patches显示文摘This paper deals with the sound insulation performance of a thin plate with interconnected distributed piezoelectric patches. Piezoelectric patches are periodically bonded on the surfaces of the plate in a collocated fashion, and are interconnected via an inductive circuit network. This piezoelectric system is termed as piezo-electromechanical(PEM) plate in the paper.Homogenization methods are involved under a sub-wavelength assumption to analytically develop the dynamical equations for the PEM plate. The dispersion relationships and energy densities of the wave modes propagating in the PEM plate are studied; the sub-wavelength assumption is verified for the simulations in this paper. The coincidence frequency of the PEM plate is researched, and results show that the coincidence frequency of the PEM plate will disappear at certain circumstances; mathematical and physical explanations are made for this phenomenon. The disappearance of the coincidence frequency is used to optimize the value of inductance, for the purpose of improving the sound transmission loss of the PEM plate. | Yi Kaijun Li Lin Mohamed Ichchou Manuel Collet | 2017 | Chinese Journal of Aeronautics2017，30，1： | 0 |
| 10 | Occurrence of Major Diseases and Insect Pests in Medium-term Growth Period of Sugarcane and The Diseases Resistance Evaluation in Guangxi显示文摘To figure out major diseases and insect pests of sugarcane and sugarcane resistance to diseases,the occurrence of major diseases and insect pests on 11 main sugarcane varieties in eight sugarcane producing areas of Guangxi was investigated during the medium-term growth period of sugarcane in 2015,and field resistance to smut and mosaic diseases was evaluated. The results showed that the dead heart rate( DHR) ranged from 0. 00% to 38. 55%; new-planting sugarcane of Guiliu 2 and ratoon sugarcane of Liucheng 05-136 suffered the most severe damage in Beihai city,and the DHR were 38. 55% and 37. 66%,respectively. The incidence rate of smut disease ranged from 0. 00% to 24. 89%. Ratoon sugarcane was more susceptible to smut than new-planting sugarcane among all investigated varieties. Variety ROC22 was most susceptible to smut,and performed moderate susceptibility. Guiliu 2 was the second susceptible and performed resistance,with the incidence rate of 7. 45%. The rest nine varieties had high resistance. Sugarcane mosaic disease occurred mildly in Guangxi,and the incidence rate ranged from 0. 39% to 7. 73%. ROC22,Guitang 42 and Guiliu 2 expressed moderate resistance and the rests exhibited resistance. Sugarcane in Nanning and Beihai suffered more severe damage than those in other producing areas. The field evaluation system of sugarcane resistance to borers was expected to be constructed. ROC22 was most susceptible to smut,compared with other main varieties. Mosaic diseases occurred lightly in Guangxi. Multi-location and multi-year observation are necessary for accurate evaluation of sugarcane resistance to smut and mosaic diseases. | Li Yijie Duan Weixing Huang Zhi Wang Zeping Li Wenjiao Wei Kaijun Lu Wenjuan Lin Shanhai | 2016 | Plant Diseases and Pests2016，7，3： | 0 |
