| 1 | Acupuncture at Baihui and Dazhui reduces brain cell apoptosis in heroin readdicts显示文摘Acupuncture at Baihui(GV20) and Dazhui(GV14) reduces neuronal loss and attenuates ultrastructural damage in cerebral ischemic rats. However, whether acupuncture can treat addiction and prevent readdiction through changes to brain cell ultrastructure remains unknown. In this study, cell apoptosis was observed in the hippocampus and frontal lobe of heroin readdicted rats by electron microscopy. Immunohistochemical staining displayed a reduction in Bcl-2 expression and an increase in Bax expression in the hippocampus and frontal lobe. After rats were given acupuncture at Baihui and Dazhui, the pathological damage in the hippocampus and frontal lobe was significantly reduced, Bcl-2 expression was upregulated and Bax expression was downregulated. Acupuncture exerted a similar effect with methadone, a commonly used drug for clinical treatment of drug addiction. Experimental findings suggest that acupuncture at Dazhui and Baihui can prevent brain cell apoptosis in heroin readdicted rats. | Xiaorong Hou Rongjun Zhang Hang Lv Xinghui Cai Guangchuan Xie Xiaoge Song | 2014 | Neural Regeneration Research2014，9，2： | 12 |
| 2 | Dynamic changes of microbial community diversity in a photohydrogen producing reactor monitored by PCR-DGGE显示文摘A PCR-DGGE (denaturing gradient gel electrophoresis of polymerase chain reaction) protocol was used for monitoring the dynamic changes in the microbial population during photohydrogen production. Total DNA was extracted directly from the mixed bacterial community in the reactor and subjected to PCR with V3-16S rDNA and pufM gene primers, and the amplifications were then analyzed by DGGE. The DGGE patterns demonstrated the dynamics of community structure and the shift of microbial diversity, which corresponded to different running periods of the reactor. The optimal hydrogen producing community formed on day 10. Using DGGE analysis with the pufM gene fragments was superior to V3-16S rDNA region genes for detecting the dynamic variations of the photosynthetic bacteria population during hydrogen production. The comparative sequence analysis of excised DGGE bands showed the relationship between specific population structures and system performance. Rhodopseudomonas palustris was presumed as one of the dominant community members for hydrogen production in the reactor. The PCR-DGGE protocol was proven to be a good tool for monitoring the photohydrogen production in real time and offered the available information to improve the photohydrogen producing system. | Yanling YING Jun CHENG | 2008 | Journal of Environmental Sciences2008，20，9： | 11 |
| 3 | Pharmacokinetics and pharmacodynamics of Shengjiang decoction in rats with acute pancreatitis for protecting against multiple organ injury显示文摘AIM To explore the pharmacokinetics and pharmacodynamics of Shengjiang decoction(SJD) in rats with acute pancreatitis(AP) for protecting against multiple organ injury.METHODS An AP model was established by retrograde perfusion of 3.5% sodium taurocholate into the biliopancreatic duct, and a control group(CG) received 0.9% sodium chloride instead. Twelve male Sprague-Dawley rats were randomly divided into a CG treated with SJD(CG + SJD) and a model group treated with SJD(MG + SJD), both of which were orally administered with SJD(5 g/kg) 2 h after surgery. Blood samples were collected via the tail vein at 10, 20, and 40 min and 1, 2, 3, 4, 6, 8, and 12 h after a single dose of SJD to detect its main components using high-performance liquid chromatography-tandem mass spectrometry. The pharmacokinetic parameters were compared. In the pharmacodynamic experiment, 18 male SpragueDawley rats were randomly divided into a CG, an AP model group(MG), and an SJD treated AP group(SJDG). Serum amylase, lipase, and inflammatory cytokines were measured, and heart, lung, liver, spleen, pancreas, kidney, and intestine tissues were collected for pathological examination.RESULTS The MG + SJD displayed significantly shorter mean residence time(MRT) and higher clearance(CL) for emodin and aloe-emodin; significantly shorter time of maximum concentration and T1/2 and a lower area under curve(AUC) for aloe-emodin; a significantly higher AUC and lower CL for rhein; and longer MRT and lower CL for chrysophanol than the CG + SJD. In the pharmacodynamic experiment, the amylase, interleukin(IL)-6, IL-10, and tumor necrosis factor(TNF)-α levels in the MG were higher than those in the CG(P < 0.05). After the herbal decoction treatment, the SJDG had higher IL-10 and lower TNF-α levels than the MG(P < 0.05). The MG had the highest pathological scores, and the pathological scores of the lung, pancreas, kidney, and intestine in the SJDG were significantly lower than those in the MG(P < 0.05).CONCLUSION AP may have varying effects on the pharmacokinetics of the major SJD components in rats. SJD might alleviate pathological injuries of the lung, pancreas, kidney, and intestine in rats with AP via regulating pro-and antiinflammatory responses, which might guide the clinical application of SJD for AP treatment. | Lv Zhu Jun-Yi Li Yu-Mei Zhang Hong-Xin Kang Huan Chen Hang Su Juan Li Wen-Fu Tang | 2017 | World Journal of Gastroenterology2017，23，46： | 10 |

| 5 | Effect of Sheng-jiang powder on multiple-organ inflammatory injury in acute pancreatitis in rats fed a high-fat diet显示文摘BACKGROUND Obesity worsens inflammatory organ injury in acute pancreatitis(AP), but there is no effective preventive strategy. Sheng-jiang powder(SJP) has been shown to alleviate multiple-organ inflammatory injury in rats with high-fat diet-induced obesity. Hence, SJP is supposed to have an effect on multiple-organ inflammatory injury in AP in rats fed a high-fat diet.AIM To explore how obesity may contribute to aggravating inflammatory organ injury in AP in rats and observe the effect of SJP on multiple-organ inflammatory injury in AP in rats fed a high-fat diet.METHODS Rats were randomly assigned to a control group(CG), an obese group(OG), and an SJP treatment group(SG), with eight rats per group. The rats in the OG and SG were fed a high-fat diet. From the third week, the rats in the SG were given oral doses of SJP(5 g/kg of body weight). After 12 wk, AP was induced in the three groups. Serum amylase level, body weight, Lee's index, serum biochemistry parameters, and serum inflammatory cytokine and tissue cytokine levels were assessed, and the tissue histopathological scores were evaluated and compared.RESULTS Compared with the CG, serum triglyceride, total cholesterol, interleukin-6, and interleukin-10 levels were significantly higher in the OG, and serum high-density lipoprotein cholesterol level was significantly lower in the OG. Moreover,enhanced oxidative damage was observed in the pancreas, heart, spleen, lung,intestine, liver, and kidney. Evidence of an imbalanced antioxidant defense system, especially in the pancreas, spleen, and intestine, was observed in the obese AP rats. Compared with the OG, serum high-density lipoprotein cholesterol, interleukin-10, and superoxide dismutase expression levels in the pancreas, spleen, and intestine were increased in the SG. Additionally, SJP intervention led to a decrease in the following parameters: body weight; Lee's index; serum triglyceride levels; serum total cholesterol levels; malondialdehyde expression levels in the pancreas, heart, spleen, lung, and liver; myeloperoxidase expression levels in the lung; and pathological scores in the liver.CONCLUSION Obesity may aggravate the inflammatory reaction and pathological multipleorgan injury in AP rats, and SJP may alleviate multiple-organ inflammatory injury in AP in rats fed a high-fat diet. | Yi-Fan Miao Hong-Xin Kang Juan Li Yu-Mei Zhang Hong-Yu Ren Lv Zhu Huan Chen Ling Yuan Hang Su Mei-Hua Wan Wen-Fu Tang | 2019 | World Journal of Gastroenterology2019，25，6： | 4 |
| 6 | Thymosin Alpha-1 Inhibits Complete Freund’s Adjuvant-Induced Pain and Production of Microglia-Mediated Pro-inflammatory Cytokines in Spinal Cord显示文摘Activation of inflammatory responses regulates the transmission of pain pathways through an integrated network in the peripheral and central nervous systems.The immunopotentiator thymosin alpha-1(Tal)has recently been reported to have anti-inflammatory and neuroprotective functions in rodents.However,how Tα1 affects inflammatory pain remains unclear.In the present study,intraperitoneal injection of Tal attenuated complete Freund's adjuvant(CFA)-induced pain hypersensitivity,and decreased the up-regulation of pro-inflammatory cytokines(TNF-α,IL-1β,and IL-6)in inflamed skin and the spinal cord.We found that CFA-induced peripheral inflammation evoked strong microglial activation,but the effect was reversed by Tα1.Notably,Tα1 reversed the CFA-induced up-regulation of vesicular glutamate transporter(VGLUT)and down-regulated the vesicular γ-aminobutyric acid transporter(VGAT)in the spinal cord.Taken together,these results suggest that Tα1 plays a therapeutic role in inflammatory pain and in the modulation of microgliainduced pro-inflammatory cytokine production in addition to mediation of VGLUT and VGAT expression in the spinal cord. | Yunlong Xu Yanjun Jiang Lin Wang Jiahua Huang Junmao Wen Hang Lv Xiaoli Wu Chaofan Wan Chuanxin Yu Wenjie Zhang Jiaying Zhao Yinqi Zhou Yongjun Chen | 2019 | Neuroscience Bulletin2019，35，4： | 4 |
| 7 | Response of Superoxide Dismutase,Catalase,and ATPase Activity in Bacteria Exposed to Acetamiprid显示文摘Objective To investigate how acetamiprid, a new insecticide, affects the activity of superoxide dismutase (SOD), catalase (CAT), and ATPase and the SOD isozyme patterns in two G- bacteria, E. coli K12 and Pse.FH2, and one G+ bacterum, B. subtilis. Methods The SOD, CAT, and ATPase specific activities of cell lysates were determined spectrophotometrically at 550 nm, 240 nm, and 660 nm, respectively, with kits A001, A016, and A007. SOD isozyme patterns were detected by native PAGE analysis. Results SOD and CAT activities in the tested bacteria increased significantly in a concentration-dependent manner after different concentrations of acetamiprid were applied. The activity of SOD in B. subtilis and Pse.FH2 was stimulated and reached the highest level after treatment with 100 mg/L acetamiprid for 0.5 h. For Pse.FH2, there was another stimulation of SOD activity after acetamiprid application for about 8.0 h and the second stimulation was stronger than the first. The stimulation by acetamiprid showed a relative lag for E. coli K12. Acetamiprid seemed to exhibit a similar effect on CAT activity of the two G- bacteria and had an evident influence on ATPase activity in the three bacteria within a relatively short period. Only one SOD isozyme was detectable in Pse.FH2 and B. subtilis, while different isozyme compositions in E. coli could be detected by native PAGE analysis. Conclusion Acetamiprid causes a certain oxidative stress on the three bacteria which may not only elevate SOD and CAT activities but also generate new SOD isozymes to antagonize oxidative stress. However, this oxidative stress lasts for a relatively short time and does not cause a long-term damage. | XIAO-HUA YAO HANG MIN ZHEN-MEI LV | 2006 | Biomedical and Environmental Sciences2006，19，4： | 4 |

| 10 | Adhesive anastomosis for organ transplantation显示文摘The recent development of tough tissue adhesives has stimulated intense interests among material scientists and medical doctors.However,these adhesives have seldom been tested in clinically demanding surgeries.Here we demonstrate adhesive anastomosis in organ transplantation.Anastomosis is commonly conducted by dense sutures and takes a long time,during which all the vessels are occluded.Prolonged occlusion may damage organs and even cause death.We formulate a tough,biocompatible,bioabsorbable adhesive that can sustain tissue tension and pressurized flow.We expose the endothelial surface of vessels onto a gasket,press two endothelial surfaces to the adhesive using a pair of magnetic rings,and reopen the bloodstream immediately.The time for adhesive anastomosis is shortened compared to the time for sutured anastomosis.We have achieved adhesive anastomosis of a great vein in transplanting the liver of a pig.After the surgery,the adhesive is absorbed,the vein heals,and the pig lives for over one month. | Kang Liu Hang Yang Gaobo Huang Aihua Shi Qiang Lu Shanpei Wang Wei Qiao Haohua Wang Mengyun Ke Hongfan Ding Tao Li Yanchao Zhang Jiawei Yu Bingyi Ren Rongfeng Wang Kailing Wang Hui Feng Zhigang Suo Jingda Tang Yi Lv | 2022 | Bioactive Materials2022，7，7： | 3 |
| 11 | Molecular basis of CONSTANS oligomerization in FLOWERING LOCUS T activation显示文摘The transcription factor CONSTANS(CO)integrates day-length information to induce the expression of florigen FLOWERING LOCUS T(FT)in Arabidopsis.We recently reported that the C-terminal CCT domain of CO forms a complex with NUCLEAR FACTOR-YB/YC to recognize multiple cis-elements in the FT promoter,and the N-terminal tandem B-box domains form a homomultimeric assembly.However,the mechanism and biological function of CO multimerization remained unclear.Here,we report that CO takes on a head-to-tail oligomeric configuration via its B-boxes to mediate FT activation in long days.The crystal structure of B-boxesCOreveals a closely connected tandem B-box fold forming a continuous head-to-tail assembly through unique CDHH zinc fingers.Mutating the key residues involved in CO oligomerization resulted in a non-functional CO,as evidenced by the inability to rescue co mutants.By contrast,a transgene encoding a human p53-derived tetrameric peptide in place of the B-boxesCOrescued co mutant,emphasizing the essential role of BboxesCO-mediated oligomerization.Furthermore,we found that the four TGTG-bearing cis-elements in FT proximal promoter are required for FT activation in long days.Our results suggest that CO forms a multimer to bind to the four TGTG motifs in the FT promoter to mediate FT activation. | Xiaolin Zeng Xinchen Lv Rui Liu Hang He Shiqi Liang Lixian Chen Fan Zhang Liu Chen Yuehui He Jiamu Du | 2022 | Journal of Integrative Plant Biology2022，64，3： | 2 |
| 12 | The transcription factors TLR1 and TLR2 negatively regulate trichome density and artemisinin levels in Artemisia annua显示文摘The important antimalarial drug artemisinin is biosynthesized and stored in Artemisia annua glandular trichomes and the artemisinin content correlates with trichome density;however,the factors affecting trichome development are largely unknown.Here,we demonstrate that the A.annua R2R3 MYB transcription factor TrichomeLess Regulator 1(TLR1)negatively regulates trichome development.In A.annua,TLR1 overexpression lines had 44.7%–64.0%lower trichome density and 11.5%–49.4%lower artemisinin contents and TLR1-RNAi lines had 33%–93.3%higher trichome density and 32.2%–84.0%higher artemisinin contents compared with non-transgenic controls.TLR1 also negatively regulates the expression of anthocyanin biosynthetic pathway genes in A.annua.When heterologously expressed in Arabidopsis thaliana,TLR1 interacts with GLABROUS3a,positive regulator of trichome development,and represses trichome development.Yeast two-hybrid and pull-down assays indicated that TLR1 interacts with the WUSCHEL homeobox(WOX)protein AaWOX1,which interacts with the LEAFY-like transcription factor TLR2.TLR2 overexpression in Arabidopsis and A.annua showed that TLR2 reduces trichome development by reducing gibberellin levels.Furthermore,artemisinin contents were 19%–43%lower in TLR2-overexpressing A.annua plants compared to controls.These data indicate that TLR1 and TLR2 negatively regulate trichome density by lowering gibberellin levels and may enable approaches to enhance artemisinin yields. | Zongyou Lv JinXing Li Shi Qiu Fei Qi Hang Su Qitao Bu Rui Jiang Kexuan Tang Lei Zhang Wansheng Chen | 2022 | Journal of Integrative Plant Biology2022，64，6： | 2 |
| 13 | Novel polybenzimidazole/graphitic carbon nitride nanosheets composite membrane for the application of acid-alkaline amphoteric water electrolysis显示文摘It is a great challenge to develop membrane materials with high performance and long durability for acidalkaline amphoteric water electrolysis.Hence,the graphitic carbon nitride(g-C_(3)N_(4))nanosheets were compounded with the(2,2'-m-phenylene)-5,5'-benzimidazole(m-PBI)matrix for the preparation of m-PBI/g-C_(3)N_(4) composite membranes.The synthesis of g-C_(3)N_(4) nanosheets and m-PBI matrix have been confirmed by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscoy(TEM)and ^(1)H nuclear magnetic resonance spectra(^(1)H NMR),respectively.The fourier transform infrared spectroscopy(FT-IR)and SEM of the composite membranes showed the g-C_(3)N_(4) nanosheets were well dispersed in the m-PBI/g-C_(3)N_(4) composite membrane.The mechanical properties test exhibited the good mechanical strength,and the TGA curves of m-PBI showed the high thermal stability of composite membranes.Besides,the m-PBI/g-C_(3)N_(4) composite membrane showed excellent proton and hydroxide ion conductivity,which was higher than pure m-PBI and Nafion 115 membrane.The acid-alkaline amphoteric water electrolysis test showed m-PBI/1%g-C_(3)N_(4) composite membrane has the best performance with a current density of 800 mA cm^(-2) at cell voltage of 1.98 V at 20℃.It showed that m-PBI/g-C_(3)N_(4) composite membrane has a good application prospect for acid-alkaline amphoteric water electrolysis. | Bo Lv Hang Yin Zhigang Shao Zoujie Luan Ziyi Huang Shucheng Sun Yue Teng Chunhui Miu Qiang Gao | 2022 | Journal of Energy Chemistry2022，31，1： | 2 |
| 14 | Rice FLOURY ENDOSPERM22, encoding a pentatricopeptide repeat protein, is involved in both mitochondrial RNA splicing and editing and is crucial for endosperm development显示文摘Most of the reported P-type pentatricopeptide repeat(PPR) proteins play roles in organelle RNA stabilization and splicing. However, P-type PPRs involved in both RNA splicing and editing have rarely been reported, and their underlying mechanism remains largely unknown. Here, we report a rice floury endosperm22(flo22) mutant with delayed amyloplast development in endosperm cells. Map-based cloning and complementation tests demonstrated that FLO22 encodes a mitochondrion-localized P-type PPR protein.Mutation of FLO22 resulting in defective transsplicing of mitochondrial nad1 intron 1 and perhaps causing instability of mature transcripts affected assembly and activity of complex Ⅰ, and mitochondrial morphology and function. RNA-seq analysis showed that expression levels of many genes involved in starch and sucrose metabolism were significantly down-regulated in the flo22mutant compared with the wild type, whereas genes related to oxidative phosphorylation and the tricarboxylic acid cycle were significantly upregulated. In addition to involvement in splicing as a P-type PPR protein, we found that FLO22 interacted with DYW3, a DYW-type PPR protein, and they may function synergistically in mitochondrial RNA editing. The present work indicated that FLO22 plays an important role in endosperm development and plant growth by participating in nad1 maturation and multi-site editing of mitochondrial messager RNA. | Hang Yang Yunlong Wang Yunlu Tian Xuan Teng Zehui Lv Jie Lei Erchao Duan Hui Dong Xue Yang Yuanyan Zhang Yinglun Sun Xiaoli Chen Xiuhao Bao Rongbo Chen Chuanwei Gu Yipeng Zhang Xiaokang Jiang Wenyu Ma Pengcheng Zhang Yi Ji Yu Zhang Yihua Wang Jianmin Wan | 2023 | Journal of Integrative Plant Biology2023，65，3： | 1 |
| 15 | Oreocharis xieyongii,an unusual new species of Gesneriaceae from western Hunan,China显示文摘A new species,Oreocharis xieyongii T.Deng,D.G.Zhang&H.Sun,from Hunan Province,central China,is described.The combination of purple zygomorphic corolla with longer adaxial lobes and exserted stamens defines the species and discriminates it from all other current Oreocharis species.Morphological traits of the new species were compared to those of two similar species,Oreocharis xiangguiensis and 0.rubrostriata.Phylogenetic analysis indicates that the new species is nested within the Oreocharis.Although only half of Oreocharis species were included in our study,evolutionary character analysis indicates that the ancestral states of the genus are likely the purple corolla,longer abaxial lip and inserted stamens.The longer adaxial lip is perhaps an apomorphy and only present in O.xieyongii and O.rubrostriata.Both morphological and molecular evidence suggest that O.xieyongii is a taxon new to science. | Zhen-Yu Lv Ziyoviddin Yusupov Dai-Gui Zhang Ya-Zhou Zhang Xiao-Shuang Zhang Nan Lin Komiljon Tojibaev Hang Sun Tao Deng | 2022 | Plant Diversity2022，44，2： | 1 |

| 19 | Investigation on micro-mechanism of palm oil as natural ester insulating oil for overheating thermal fault analysis of transformers显示文摘In order to explore the pyrolysis mechanism of palm oil as the natural ester insulating liquid from the molecular aspect,the ReaxFF reactive force field was used to simulate the pyrolysis process of palm oil.Firstly,the molecular models of the four main molecules of palm oil-tripalmitin,trilinolein,triolein,and tristearin-are constructed via density functional theory(DFT).Secondly,the vibrational frequencies of the four molecules are calculated,so as to calculate the infrared(IR)spectra.Thirdly,molecular dynamics(MD)simulations employing the ReaxFF method are performed to simulate the pyrolysis reaction of the palm oil system under different temperatures,so as to observe the generation pathways of major products used in the dissolved gas analysis(DGA)in the transformer thermal fault analysis.Finally,hydrogen bonds in the pyrolysis process are counted.It is found that the number of hydrogen bonds gradually increased with the increase of pyrolysis time and pyrolysis temperature.It reveals why the life of the insulating paper immersed with natural esters is prolonged,and why the breakdown voltage is reduced slowly in the actual experiment from another perspective.This study can provide theoretical guidance and effective reference for the thermal fault analysis of an insulating liquid using palm oil as raw material. | Hanbo Zheng Xufan Li Yongji Feng Hang Yang Weijie Lv | 2022 | High Voltage2022，7，4： | 1 |
