| 2 | Stability of SARS Coronavirus in Human Specimens and Environment and Its Sensitivity to Heating and UV Irradiation显示文摘The causal agent for SARS is considered as a novel coronavirus that has never been described both in human and animals previously. The stability of SARS coronavirus in human specimens and in environments was studied. Methods Using a SARS coronavirus strain CoV-P9,which was isolated from pharyngeal swab of a probable SARS case in Beijing, its stability in mimic human specimens and in mimic environment including surfaces of commonly used materials or in household conditions, as well as its resistances to temperature and UV irradiation were analyzed. A total of 106 TCID50 viruses were placed in each tested condition, and changes of the viral infectivity in samples after treatments were measured by evaluating cytopathic effect (CPE) in cell line Vero-E6 at 48 h after infectionn. Results The results showed that SARS coronavirus in the testing condition could survive in serum, 1:20 diluted sputum and feces for at least 96 h, whereas it could remain alive in urine for at least 72 h with a low level of infectivity. The survival abilities on the surfaces of eight different materials and in water were quite comparable, revealing reduction of infectivity after 72 to 96 h exposure. Viruses stayed stable at 4℃, at room temperature (20℃) and at 37℃ for at least 2 h without remarkable change in the infectious ability in cells, but were convened to be non-infectious after 90-, 60- and 30-min exposure at 56℃, at 67℃ and at 75℃, respectively. Irradiation of UV for 60 min on the virus in culture medium resulted in the destruction of viral infectivity at an undetectable level. Conclusion The survival ability of SARS coronavirus in human specimens and in environments seems to be relatively strong. Heating and UV irradiation can efficiently eliminate the viral infectivity. | SHU-MING DUAN, XIN-SHENG ZHAO, RUI-FU WEN, JING-JING HUANG, GUO-HUA PI, SU-XIANG ZHANG, JUN HAN, SHENG-LI BI, LI RUAN, XIAO-PING DONGAND SARS RESEARCH TEAMInstitute for Viral Disease Control and Prevention, Chinese Center for Disease Control and Prevention,Ying-Xin Rd. 100, Beijing 100052, China | 2003 | Biomedical and Environmental Sciences2003，16，3： | 29 |

| 5 | Groundwater Contamination with NO_3-N in a Wheat-Corn Cropping System in the North China Plain显示文摘The North China Plain,where summer corn(Zea mays L.)and winter wheat(Triticum aestivum L.)are the major crops grown,is a major agricultural area in China.Permeable soils make the region susceptible to groundwater pollution by NO_3-N,which is applied to fields in large amounts of more than 400 kg NO_3-N ha^(-1)as fertilizer.A field experiment was established in 2002 to examine the relationship among N fertilization rate,soil NO_3-N,and NO_3-N groundwater contamination.Two adjacent fields were fertilized with local farmers' N fertilization rate(LN)and double the normal application rate(HN),respectively,and managed under otherwise identical conditions.The fields were under a traditional summer corn/winter wheat rotation.Over a 22-month period,we monitored NO_3-N concentrations in both bulk soil and soil pore water in 20-40 cm increments up to 180 cm depth.We also monitored NO_3-N concentrations in groundwater and the depth of the groundwater table.No significant differences in soil NO_3-N were observed between the LN and HN treatment.We identified NO_3-N plumes moving downward through the soil profile.The HN treatment resulted in significantly higher groundwater NO_3-N,relative to the LN treatment,with groundwater NO_3-N consistently exceeding the maximum safe level of 10 mg L^(-1),but groundwater NO_3-N above the maximum safe level was also observed in the LN treatment after heavy rain.Heavy rain in June,July,and August 2003 caused increased NO_3-N leaching through the soil and elevated NO_3-N concentrations in the groundwater.Concurrent rise of the groundwater table into NO_3-N- rich soil layers also contributed to the increased NO_3-N concentrations in the groundwater.Our results indicate that under conditions of average rainfall,soil NO_3-N was accumulated in the soil profile.The subsequent significantly higher- than-average rainfalls continuously flushed the soil NO_3-N into deeper layers and raised the groundwater table,which caused continuous groundwater contamination with NO_3-N.The results suggest that under common farming practices in the North China Plain,groundwater contamination with NO_3-N was likely,especially during heavy rainfalls,and the degree of groundwater contamination appeared to be proportional to the N application rates.Decreasing fertilization rates, splitting fertilizer inputs,and optimizing irrigation scheduling had potential to reduce groundwater NO_3-N contamination. | ZHAO Bing-Zi ZHANG Jia-Bao M.

| 6 | Efficacy and safety of metformin and sitagliptin based triple antihyperglycemic therapy(STRATEGY):a multicenter,randomized,controlled,non-inferiority clinical trial显示文摘Despite the current guideline's recommendation of a timely stepwise intensification therapy,the 'clinical inertia',termed as the delayed treatment intensification,commonly exists in the real world,which may be partly due to the relatively little substantial evidence and no clear consensus regarding the efficacy and safety of triple oral agents in patients inadequately controlled with dual therapy.In this clinical trial performed in 237 centers in China,5,535 type 2 diabetic patients inadequately controlled by previous therapies were treated with a stable metformin/sitagliptin dual therapy for 20 weeks.The patients who did not reach the glycated hemoglobin A1c(HbA1c) goal were then further randomized into glimepiride,gliclazide,repaglinide,or acarbose group for an additional 24-week triple therapy.A mean HbAlc reduction of 0.85%was observed when sitagliptin was added to the patients inadequately controlled with metformin in 16 weeks.Further HbAlc reductions in the 24-week triple therapy stage were 0.65%in glimepiride group,0.70%in gliclazide group,0.61%in repaglinide group,and 0.45%in acarbose group.The non-inferiority criterion for primary hypotheses was met for gliclazide and repaglinide,but not for acarbose,compared with glimepiride,when added to metformin/sitagliptin dual therapy.The incidences of adverse events(AEs) were 29.2%in the dual therapy stage and30.3%in the triple therapy stage.Metformin/sitagliptin as baseline therapy,with the addition of a third oral antihyperglycemic agent,including glimepiride,gliclazide,repaglinide,or acarbose,was effective,safe and well-tolerated for achieving an HbAlc<7.0%goal in type 2 diabetic patients inadequately controlled with previous therapies.The timely augmentation of up to three oral antihyperglycemic agents is valid and of important clinical benefit to prevent patients from exposure to unnecessarily prolonged hyperglycemia. | Wen Xu Yiming Mu Jiajun Zhao Dalong Zhu Qiuhe Ji Zhiguang Zhou Bin Yao Anhua Mao Samuel S.Engel Bin Zhao Yan Bi Longyi Zeng Xingwu Ran Juming Lu Linong Ji Wenying Yang Weiping Jia Jianping Weng | 2017 | Science China(Life Sciences)2017，60，3： | 19 |
| 7 | Ligustilide protects PC12 cells from oxygen-glucose deprivation/reoxygenation-induced apoptosis via the LKB1-AMPK-mTOR signaling pathway显示文摘Autophagy has been shown to have a protective effect against brain damage.Ligustilide(LIG)is a bioactive substance isolated from Ligusticum chuanxiong,a traditional Chinese medicine.LIG has a neuroprotective effect;however,it is unclear whether this neuroprotective effect involves autophagy.In this study,PC12 cells were treated with 1×10^-5–1×10^-9 M LIG for 0,3,12 or 24 hours,and cell proliferation was evaluated using the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium(MTS)assay.Treatment with 1×10^-6 M LIG for 3 hours had the greatest effect on cell proliferation,and was therefore used for subsequent experiments.PC12 cells were pre-treated with 1×10^-6 M LIG for 3 hours,cultured in 95%N2/5%CO2 in Dulbecco’s modified Eagle’s medium without glucose or serum for 4 hours,and then cultured normally for 16 hours,to simulate oxygen-glucose deprivation/reoxygenation(OGD/R).Cell proliferation was assessed with the MTS assay.Apoptosis was detected by flow cytometry.The expression levels of apoptosis-related proteins,Bcl-2 and Bax,autophagy-related proteins,Beclin 1 and microtubule-associated protein l light chain 3B(LC3-II),and liver kinase B1(LKB1)-5′-adenosine monophosphate-activated protein kinase(AMPK)-mammalian target of rapamycin(mTOR)signaling pathway-related proteins were assessed by western blot assay.Immunofluorescence staining was used to detect LC3-II expression.Autophagosome formation was observed by electron microscopy.LIG significantly decreased apoptosis,increased Bcl-2,Beclin 1 and LC3-II expression,decreased Bax expression,increased LC3-II immunoreactivity and the number of autophagosomes,and activated the LKB1-AMPK-mTOR signaling pathway in PC12 cells exposed to OGD/R.The addition of the autophagy inhibitor 3-methyladenine or dorsomorphin before OGD/R attenuated the activation of the LKB1-AMPK-mTOR signaling pathway in cells treated with LIG.Taken together,our findings show that LIG promotes autophagy and protects PC12 cells from apoptosis induced by OGD/R via the LKB1-AMPK-mTOR signaling pathway. | Dan-Yang Zhao Dong-Dong Yu Li Ren Guo-Rong Bi | 2020 | Neural Regeneration Research2020，15，3： | 17 |
| 8 | The HuangZaoSi Maize Genome Provides Insights into Genomic Variation and Improvement History of Maize显示文摘Maize is a globally important crop that was a classic model plant for genetic studies. Here, we report a 2.2 Gb draft genome sequence of an elite maize line, HuangZaoSi (HZS). Hybrids bred from HZS-improved lines (HILs) are planted in more than 60% of maize fields in China. Proteome clustering of six completed sequeneed maize genomes show that 638 proteins fall into 264 HZS-specific gene families with the majority of contributions from tandem duplication events. Resequencing and comparative analysis of 40 HZSrelated lines reveals the breeding history of HILs. More than 60% of identified selective sweeps were clustered in identity.by.descent conserved regions, and yield-related genes/QTLs were enriched in HZS characteristic selected regions. Furthermore, we dem on strated that HZS-specific family genes were not uniformly distributed in the genome but enriched in improvement/function.related genomic regions. This study provides an important and novel resource for maize genome research and expands our knowledge on the breadth of genomic variation and improvement history of maize. | Chunhui Li Wei Song Yingfeng Luo Shenghan Gao Ruyang Zhang Zi Shi Xiaqing Wang Ronghuan Wang Fengge Wang Jidong Wang Yanxin Zhao Aiguo Su Shuai Wang Xin Li Meijie Luo Shuaishuai Wang Yunxia Zhang Jianrong Ge Xinyu Tan Ye Yuan Xiaochun Bi Hang He Jianbing Yan Yuandong Wang Songnian Hu Jiuran Zhao | 2019 | Molecular Plant2019，12，3： | 15 |
| 9 | Genesis of the Wulong gold deposit,Liaoning Province,NE China:Constrains from noble gases,radiogenic and stable isotope studies显示文摘TheWulong lode deposit contains over 80 tonnes of gold with an average grade of 5.35 g/t.It is one of the largest deposits in Dandong City,Liaoning Province in northeast China.Previous studies on the deposit focused on its geological characteristics,geochemistry,fluid inclusions,and the timing of gold mineralization.However,controversy remains regarding the origin of the ore-forming fluids and metals,and the genesis of the gold deposit.This paper presents zircon UePb and pyrite RbeSr ages and S,Pb,He,and Ar isotopic results along with quartz H and O isotopic data for all litho-units associated with the deposit.Laser ablation inductively coupled mass spectrometry measurements yielded zircon UePb dates for samples of pre-mineralization rocks like granite porphyry dike,the Sanguliu granodiorite,fine-grained diorite,and syn-mineralization diorite,as well as post-mineralization dolerite,and lamprophyre;their emplacement ages are 1261 Ma,1241 Ma,1231 Ma,1201 Ma,1192 Ma,and 1152 Ma,respectively.The pyrite RbeSr isochron age is 1191 Ma,indicating that both magmatism and mineralization occurred during the Early Cretaceous.The d18OH2O values of ore-forming hydrothermal fluids from the quartzepolymetallic sulfide vein stage vary from 4.8&to 6.5&,and the dDV-SMOW values are between67.7&and75.9&,indicating that the ore-forming fluids were primarily magmatic.The noble gas isotope compositions of fluid inclusions hosted in pyrite suggest that the ore-forming fluids were dominantly derived from crustal sources with minor mantle input.Sulfur isotopic values of pyrite vary between 0.2&and 3.5&,suggesting that S was derived from a homogeneous magmatic source or possibly from fluids derived from the crust.The Pb isotopic compositions of sulfides(207Pb/204Pb?15.51 e15.71,206Pb/204Pb?17.35e18.75,208Pb/204Pb?38.27e40.03)indicate that the Pb of the Wulong gold deposit is a mixture of crust and mantle components.Geochronological and geochemical data,together with the regional geological history,indicate that Early Cretaceous magmatism and mineralization of the Wulong gold deposit occurred during the rollback of the subducting Paleo-Pacific Plate,which resulted in lithospheric thinning and the destruction of the North China Craton(NCC),which indicates that the deposit is of magmaticehydrothermal origin. | Peng Zhang Linlin Kou Yan Zhao Zhongwei Bi Deming Sha Renping Han Zhumin Li | 2020 | Geoscience Frontiers2020，11，2： | 13 |
| 10 | Molecular detection of epithelial-mesenchymal transition markers in circulating tumor cells from pancreatic cancer patients:Potential role in clinical practice显示文摘AIM To evaluate the clinical properties of three subpopulations of circulating tumor cells(CTCs) undergoing epithelial-mesenchymal transition(EMT) in pancreatic ductal adenocarcinoma(PDAC) patients.METHODS We identified CTCs for expression of the epithelial cell marker cytokeratin or epithelial cell adhesion molecule(EpCAM)(E-CTC), the mesenchymal cell markers vimentin and twist(M-CTC), or both(E/M-CTC) using the CanPatrol system. Between July 2014 and July 2016, 107 patients with PDAC were enrolled for CTC evaluation. CTC enumeration and classification were correlated with patient clinicopathological features and outcomes.RESULTS CTCs were detected in 78.5% of PDAC patients. The number of total CTCs ranged from 0 to 26 across all 107 patients, with a median value of six. CTC status correlated with lymph node metastasis, TNM stage, distant metastasis, blood lymphocyte counts, and neutrophil-to-lymphocyte ratio(NLR). Kaplan-Meier survival analysis showed that patients with ≥ 6 total CTCs had significantly decreased overall survival and progression-free survival compared with patients with < 6 total CTCs. The presence of M-CTCs was positively correlated with TNM stage(P < 0.01) and distant metastasis(P < 0.01). Additionally, lymphocyte counts and NLR in patients without CTCs were significantly different from those in patients testing positive for each CTC subpopulation(P < 0.01).CONCLUSION Classifying CTCs by EMT markers helps to identify the more aggressive CTC subpopulations and provides useful evidence for determining a suitable clinical approach. | Xiao-Hui Zhao Zai-Rui Wang Chang-Long Chen Ling Di Zhuo-Fei Bi Zhi-Hua Li Yi-Min Liu | 2019 | World Journal of Gastroenterology2019，25，1： | 13 |

| 12 | Effect of artesunate supplementation on bacterial translocation and dysbiosis of gut microbiota in rats with liver cirrhosis显示文摘AIM: To evaluate the effect of artesunate(AS) supplementation on bacterial translocation(BT) and gut microbiota in a rat model of liver cirrhosis. METHODS: Fifty-four male Sprague-Dawley rats were randomly divided into a normal control group(N), a liver cirrhosis group(M) and a liver cirrhosis group intervened with AS(MA). Each group was sampled at 4, 6 and 8 wk. Liver cirrhosis was induced by injection of carbon tetrachloride(CCl4), intragastric administration of 10% ethanol, and feeding a high fat diet. Rats in the MA group were intragastrically administered with AS(25 mg/kg body weight, once daily). Injuries of the liver and intestinal mucosa were assessed by hematoxylineosin or Masson's trichrome staining. Liver index was calculated as a ratio of the organ weight(g) to body weight(g). The gut microbiota was examined by automated ribosomal intergenic-spacer analysis of fecal DNA. BT was assessed by standard microbiological techniques in the blood, mesenteric lymph nodes(MLNs), liver, spleen, and kidney. RESULTS: Compared to group N, the body weight was reduced significantly in groups M and MA due to the development of liver cirrhosis over the period of 8 wk. The body weight was higher in group MA than in group M. The liver indices were significantly elevated at 4, 6 and 8 wk in groups M and MA compared to group N. AS supplementation partially decreased the liver indices in group MA. Marked histopathologic changes in the liver and small intestinal mucosa in group M were observed, which were alleviated in group MA. Levels of pro-inflammatory interleukin-6 and tumor necrosis factor-α were significantly elevated at 8 wk in ileal homogenates in group M compared to group N, which were decreased after AS supplementation in group MA. The dysbiosis of gut microbiota indicated by the mean diversity(Shannon index) and mean similarity(Sorenson index) was severe as the liver cirrhosis developed, and AS supplementation had an apparent intervention effect on the dysbiosis of gut microbiota at 4 wk. The occurrence of BT was increased in the liver of group M compared to that of group N. AS supplementation reduced BT in group MA at 8 wk. BT also occurred in the MLNs, spleen, and kidney, which was reduced by AS supplementation. BT was not detected in the blood in any group.CONCLUSION: Dysbiosis of gut microbiota, injury of intestinal mucosal barrier and BT occurred as liver cirrhosis progressed, which might enhance inflammation and aggravate liver injury. AS may have other nonantimalarial effects that modulate gut microbiota,inhibit BT and alleviate inflammation, resulting in a reduction in CCl4, alcohol and high fat-caused damages to the liver and intestine. | Yun-Xia Chen Li-Na Lai Hui-Ying Zhang Yang-Hui Bi Li Meng Xu-Jiong Li Xiao-Xia Tian Li-Min Wang Yi-Min Fan Zhong-Fu Zhao De-Wu Han Cheng Ji | 2016 | World Journal of Gastroenterology2016，22，10： | 10 |

| 14 | Resequencing of 145 Landmark Cultivars Reveals Asymmetric Sub-genome Selection and Strong Founder Genotype Effects on Wheat Breeding in China显示文摘Controlled pedigrees and the multi-decade timescale of national crop plant breeding programs offer a unique experimental context for examining how selection affects plant genomes.More than 3000 wheat cultivars have been registered,released,and documented since 1949 in China.In this study,a set of 145 elite cultivars selected from historical points of wheat breeding in China were re-sequenced.A total of 43.75 Tb of sequence data were generated with an average read depth of 17.94x for each cultivar,and more than 60.92 million SNPs and 2.54 million InDels were captured,based on the Chinese Spring RefSeq genome v1.0.Seventy years of breeder-driven selection led to dramatic changes in grain yield and related phenotypes,with distinct genomic regions and phenotypes tar-geted by different breeders across the decades.There are very clear instances illustrating how introduced Italian and otherforeign germplasm was integrated into Chinese wheat programs and reshaped the genomic landscape of local modern cultivars.Importantly,the resequencing data also highlighted significant asymmetric breeding selec-tion among the three sub-genomes:this was evident in both the collinear blocks for homeologous chromosomes and among sets of three homeologous genes.Accumulation of more newly assembled genes in newer cultivars implied the potential value of these genes in breeding.Conserved and extended sharing of linkage disequilibrium(LD)blocks was highlighted among pedigree-related cultivars,in which fewer haplotype differences were detected.Fixation or replacement of haplotypes from founder genotypes after generations of breeding was related to their breeding value.Based on the haplotype frequency changes in LD blocks of pedigree-related cultivars,we propose a strategy for evaluating the breeding value of any given line on the basis of the accumulation(pyramiding)of bene-ficial haplotypes.Collectively,our study demonstrates the influence of 'founder genotypes' on the output of breeding efforts over many decades and also suggests that founder genotype perspectives are in fact more dy-namic when applied in the context of modern genomics-informed breeding. | Chenyang Hao Chengzhi Jiao Jian Hou Tian Li Hongxia Liu Yuquan Wang Jun Zheng Hong Liu Zhihong Bi Fengfeng Xu Jing Zhao Lin Ma Yamei Wang Uzma Majeed Xu Liu Rudi Appels Marco Maccaferri Roberto Tuberosa Hongfeng Lu Xueyong Zhang | 2020 | Molecular Plant2020，13，12： | 9 |

| 16 | Combination of mild therapeutic hypothermia and adipose-derived stem cells for ischemic brain injury显示文摘Mild therapeutic hypothermia has been shown to mitigate cerebral ischemia, reduce cerebral edema, and improve the prognosis of patients with cerebral ischemia. Adipose-derived stem cell-based therapy can decrease neuronal death and infiltration of inflammatory cells, exerting a neuroprotective effect. We hypothesized that the combination of mild therapeutic hypothermia and adipose-derived stem cells would be neuroprotective for treatment of stroke. A rat model of transient middle cerebral artery occlusion was established using the nylon monofilament method. Mild therapeutic hypothermia(33°C) was induced after 2 hours of ischemia. Adipose-derived stem cells were administered through the femoral vein during reperfusion. The severity of neurological dysfunction was measured by a modified Neurological Severity Score Scaling System. The area of the infarct lesion was determined by 2,3,5-triphenyltetrazolium chloride staining. Apoptotic neurons were detected by terminal deoxynucleotidyl transferase-mediated d UTP-biotin nick end labeling(TUNEL) staining. The regeneration of microvessels and changes in the glial scar were detected by immunofluorescence staining. The inflammatory responses after ischemic brain injury were evaluated by in situ staining using markers of inflammatory cells. The expression of inflammatory cytokines was measured by reverse transcription-polymerase chain reaction. Compared with mild therapeutic hypothermia or adipose-derived stem cell treatment alone, their combination substantially improved neurological deficits and decreased infarct size. They synergistically reduced the number of TUNEL-positive cells and glial fibrillary acidic protein expression, increased vascular endothelial growth factor levels, effectively reduced inflammatory cell infiltration and down-regulated the m RNA expression of the proinflammatory cytokines interleukin-1β, tumor necrosis factor-α and interleukin-6. Our findings indicate that combined treatment is a better approach for treating stroke compared with mild therapeutic hypothermia or adipose-derived stem cells alone. | Kai Zhao Rui Li Sheng Bi Yu Li Long Liu Yu-Long Jia Peng Han Chang-Cong Gu Xi-Ze Guo Wan-Ping Zhang Chun Wang Chun-Ying Pei Lin-Lu Tian Li-Xian Li | 2018 | Neural Regeneration Research2018，13，10： | 9 |
| 17 | Baicalin attenuates blood-spinal cord barrier disruption and apoptosis through PI3K/Akt signaling pathway after spinal cord injury显示文摘Baicalin is a natural active ingredient isolated from Scutellariae Radix that can cross the blood-brain barrier and exhibits neuroprotective effects on multiple central nervous system diseases.However,the mechanism behind the neuroprotective effects remains unclear.In this study,rat models of spinal cord injury were established using a modified Allen's impact method and then treated with intraperitoneal injection of Baicalin.The results revealed that Baicalin greatly increased the Basso,Beattie,Bresnahan Locomotor Rating Scale score,reduced blood-spinal cord barrier permeability,decreased the expression of Bax,Caspase-3,and nuclear factorκB,increased the expression of Bcl-2,and reduced neuronal apoptosis and pathological spinal cord injury.SH-SY5 Y cell models of excitotoxicity were established by application of 10 m M glutamate for 12 hours and then treated with 40μM Baicalin for 48 hours to investigate the mechanism of action of Baicalin.The results showed that Baicalin reversed tight junction protein expression tendencies(occludin and ZO-1)and apoptosis-related protein expression(Bax,Bcl-2,Caspase-3,and nuclear factor-κB),and also led to up-regulation of PI3 K and Akt phosphorylation.These effects on Bax,Bcl-2,and Caspase-3 were blocked by pretreatment with the PI3 K inhibitor LY294002.These findings suggest that Baicalin can inhibit bloodspinal cord barrier permeability after spinal cord injury and reduce neuronal apoptosis,possibly by activating the PI3 K/Akt signaling pathway.This study was approved by Animal Ethics Committee of Xi'an Jiaotong University on March 6,2014. | Rui Zhao Xue Wu Xue-Yuan Bi Hao Yang Qian Zhang | 2022 | Neural Regeneration Research2022，17，5： | 9 |

| 19 | Mitochondrial Modulation of Apoptosis Induced by Low-dose Radiation in Mouse Testicular Cells显示文摘Objective To investigate whether apoptosis induced by low-dose radiation(LDR) is regulated by mitochondrial pathways in testicular cells.Methods Male mice were exposed to whole-body LDR,and changes in mitochondrial function and in expression of apoptotic factors were analyzed in the testicular cells as follows.Total nitric-oxide synthase(T-NOS) and Na+/K+ATPase activities were biochemically assayed.Reactive oxygen species(ROS) and mitochondrial membrane potential(Δψm) were determined by flow cytometry using fluorescent probes.Levels of mRNAs encoding cytochrome c(Cyt c) and apoptosis-inducing factor(AIF) were quantified by real-time reverse-transcription PCR(RT-PCR).Expression of Cyt c,AIF,caspase-9,and caspase-3 at the proteinlevel was assessed by western blotting and immunohistochemistry.Results LDR induced an increase in T-NOS activity and ROS levels,and a decrease in Na+/K+ATPase activity and mitochondrial Δψm,in the testicular cells.The intensity of these effects increased with time after irradiation and with dose.The cells showed remarkable swelling and vacuolization of mitochondria,and displayed a time- and dose-dependent increase in the expression of Cyt c,AIF,procaspase-9,and procaspase-3.Activation of the two procaspases was confirmed by detection of the cleaved caspases.The changes in expression of the four apoptotic factors were mostly limited to spermatogonia and spermatocytes.Conclusion LDR can induce testicular cell apoptosis through mitochondrial signaling pathways. | FANG Fang GONG Ping Sheng ZHAO Hong Guang BI Yu Jing ZHAO Gang GONG Shou Liang WANG Zhi Cheng | 2013 | Biomedical and Environmental Sciences2013，26，10： | 9 |
| 20 | Task-related functional magnetic resonance imaging-based neuronavigation for the treatment of depression by individualized repetitive transcranial magnetic stimulation of the visual cortex显示文摘To determine whether repetitive transcranial magnetic stimulation(rTMS)of the visual cortex(VC)provides effective and welltolerated treatment and whether magnetic resonance imaging(MRI)measures functional change of the VC as a biomarker of therapeutic effect in major depressive disorder(MDD),we performed a sham-controlled,double-blind,randomized,three-arm VC rTMS treatment study in 74 MDD patients.Neuronavigated rTMS(10 Hz,90%of resting motor threshold,1,600 pulses over20 min twice per day)was performed over the VC for five days.Clinical outcome was measured by Hamilton Depression Rating Scale(HAMD-24)at days 0,1,3,5 and after terminating rTMS,with follow-up at four weeks.MRI was measured at days 0 and5.The individualized group exhibited the greatest change in HAMD-24 scores after VC rTMS for 5 days(F=5.53,P=0.005),which were maintained during follow-up period(F=4.22,P=0.016).All patients reported good tolerance.Changes in VC taskrelated functional MRI correlated with symptomatic reduction in the individualized group.Treatment reduced the initially abnormal increase in resting state functional connectivity from the VC to the pre/subgenual anterior cingulate cortex at day 5,especially in the individualized group.We demonstrated therapeutic potential and good tolerance of VC rTMS in MDD patients,indicated by biomarkers of f MRI measurement. | Zhijun Zhang Hongxing Zhang Chun-Ming Xie Meng Zhang Yachen Shi Ruize Song Xiang Lu Haisan Zhang Kun Li Bi Wang Yongfeng Yang Xianrui Li Jianli Zhu Yang Zhao Ti-Fei Yuan Georg Northoff | 2021 | Science China(Life Sciences)2021，64，1： | 8 |
