| 1 | Effect of Lichong decoction on expression of Bcl-2 and Bcl-2-associated X protein mRNAs in hysteromyoma model rat显示文摘OBJECTIVE:To study on effects of Lichong decoction on expression of apoptosis-controlling genes,Bcl-2 and Bcl-2-associated X protein(Bax) mRNAs in hysteromyoma tissue of the hysteromyoma model rat.METHODS:Fifty Wistar female rats were randomly divided into a normal group,a model group,a Lichong decoction group,a Guizifuling capsule group and a Mifepristone group.The hysteromyoma rat model was established by intraperitoneal injection of exogenous estrin and progestogens.Pathological examination of uterine tissue,uterine coefficient and uterine transverse diameter were made under optic microscope and expressions of Bcl-2 and Bax mRNAs in uterine tissue in the groups were detected with real-time fluorescent quantitative polymerase chain reaction(PCR) technique.RESULTS:After treatment,under microscope it was found that in the Lichong decoction group myometrium thinned,muscle fiber slightly overgrowth or long and thin,regular arrangement,inserting phenomenon of inner circular muscle and external longitudinal muscle was occasionally or not seen in the Lichong decoction group.The uterine coefficient and the uterine transverse diameter significantly decreased(P<0.01),and Bcl-2 mRNA expression significantly decreased(P<0.01) and Bax mRNA expression significantly increased in hysteromyoma tissue(P<0.01) in the Lichong decoction group as compared with the model group.CONCLUSION:Therapeutic effects of Lichong decoction on hysteromyoma is related with decrease of Bcl-2 mRNA expression and increase of Bax mRNA expression. | Donghua Li Xin Xu Ruiya Qian Jianguo Geng Yan Zhang Xiaolei Xie Yasong Wang Xiaoli Zou | 2013 | Journal of Traditional Chinese Medicine2013，33，2： | 24 |
| 2 | Altered trends in carbon uptake in China’s terrestrial ecosystems under the enhanced summer monsoon and warming hiatus显示文摘The carbon budgets in terrestrial ecosystems in China are strongly coupled with climate changes.Over the past decade,China has experienced dramatic climate changes characterized by enhanced summer monsoon and decelerated warming.However,the changes in the trends of terrestrial net ecosystem production(NEP)in China under climate changes are not well documented.Here,we used three ecosystem models to simulate the spatiotemporal variations in China's NEP during 1982–2010 and quantify the contribution of the strengthened summer monsoon and warming hiatus to the NEP variations in four distinct climatic regions of the country.Our results revealed a decadal-scale shift in NEP from a downtrend of–5.95 Tg C/yr^2(reduced sink)during 1982–2000 to an uptrend of 14.22 Tg C/yr^2(enhanced sink)during 2000–10.This shift was essentially induced by the strengthened summer monsoon,which stimulated carbon uptake,and the warming hiatus,which lessened the decrease in the NEP trend.Compared to the contribution of 56.3%by the climate effect,atmospheric CO2 concentration and nitrogen deposition had relatively small contributions(8.6 and 11.3%,respectively)to the shift.In conclusion,within the context of the global-warming hiatus,the strengthening of the summer monsoon is a critical climate factor that enhances carbon uptake in China due to the asymmetric response of photosynthesis and respiration.Our study not only revealed the shift in ecosystem carbon sequestration in China in recent decades,but also provides some insight for understanding ecosystem carbon dynamics in other monsoonal areas. | Honglin He Shaoqiang Wang Li Zhang Junbang Wang Xiaoli Ren Lei Zhou Shilong Piao Hao Yan Weimin Ju Fengxue Gu Shiyong Yu Yuanhe Yang Miaomiao Wang Zhongen Niu Rcmg Ge Huimin Yan Mei Huang Guoyi Zhou Yongfei Bai Zongqiang Xie Zhiyao Tang Bingfang Wu Leiming Zhang Nianpeng He Qiufeng Wang Guirui Yu | 2019 | National Science Review2019，6，3： | 24 |
| 3 | Effect of Lichong Decoction on expression of IGF-I and proliferating cell nuclear antigen mRNA in rat model of uterine leiomyoma显示文摘OBJECTIVE:To study the effect of Lichong Decoction(Lichong Decoction for strengthening anti-pathogenic Qi and eliminating blood stasis) on the expression of insulin-like growth factor-I(IGF-I) and proliferating cell nuclear antigen(PCNA) mRNA in a rat model of uterine leiomyoma.METHODS:Fifty female Wistar rats were randomized into a normal control group,model group,Lichong Decoction group,Guizhifuling Capsule(Capsule containing Cassia Twig and Poria) group,and Mifepristone group.The uterine leiomyoma model was established by peritoneal injections of exogenous estrogen and progesterone hormone.The ultrastructural changes in cells of rat uterine tissues were observed with transmission electron microscopy,and the expression of IGF-I and PCNA mRNA was detected by real-time fluorescent quantitative PCR.RESULTS:Following treatment,cells in the Lichong Decoction group appeared to be arranged normally,the cellular morphology were almost in a normal state,hyperplasia and hypertrophy of the chondriosome was reduced,collagen fibers were arranged in a regular manner,without obvious hyperplasia,and the expression of IGF-I and PCNA mRNA was significantly decreased compared with the model group(P<0.01).CONCLUSIONS:The effect of Lichong Decoction on uterine leiomyoma is related to its function in reducing the expression of IGF-I and PCNA mRNA. | Donghua Li Yalan Zhang Hongjuan Han Jianguo Geng Xiaolei Xie Jiubo Zheng Yasong Wang Xiaoli Zou | 2012 | Journal of Traditional Chinese Medicine2012，32，4： | 11 |
| 4 | Head-related transfer function database and its analyses显示文摘Based on the measurements from 52 Chinese subjects (26 males and 26 females), a high-spatial-resolution head-related transfer function (HRTF) database with corre- sponding anthropometric parameters is established. By using the database, cues relating to sound source localization, including interaural time difference (ITD), interaural level difference (ILD), and spectral features introduced by pinna, are analyzed. Moreover, the statistical relationship between ITD and anthropometric parameters is estimated. It is proved that the mean values of maximum ITD for male and female are significantly different, so are those for Chinese and western sub- jects. The difference in ITD is due to the difference in individual anthropometric parameters. It is further proved that the spectral features introduced by pinna strongly depend on individual; while at high frequencies (f≥ 5.5 kHz), HRTFs are left-right asymmetric. This work is instructive and helpful for the research on bin- aural hearing and applications on virtual auditory in future. | XIE BoSun ZHONG XiaoLi RAO Dan LIANG ZhiQiang | 2007 | Science China(Physics,Mechanics & Astronomy)2007，50，3： | 10 |
| 5 | The Impact of Genomic Prof ling for Novel Cancer Therapy–Recent Progress in Non-Small Cell Lung Cancer显示文摘There is high expectation for significant improvements in cancer patient care after completion of the human genome project in 2003.Through pains-taking analyses of genomic profiles in cancer patients,a number of targetable gene alterations have been discovered,with some leading to novel therapies,such as activating mutations of EGFR,BRAF and ALK gene fusions.As a result,clinical management of cancer through targeted therapy has finally become a reality for a subset of cancers,such as lung adenocarcinomas and melanomas.In this review,we summarize how gene mutation discovery leads to new treatment strategies using non-small cell lung cancer(NSCLC)as an example.We also discuss possible future implications of cancer genome analyses. | Jingwu Xie Xiaoli Zhang | 2016 | Journal of Genetics and Genomics2016，43，1： | 9 |
| 6 | The role of GLI2-ABCG2 signaling axis for 5Fu resistance in gastric cancer显示文摘Gastric cancer is a leading cause of cancer-related mortality worldwide, and options to treat gastric cancer are limited. Fluorouracil(5Fu)-based chemotherapy is frequently used as a neoadjuvant or an adjuvant agent for gastric cancer therapy. Most patients with advanced gastric cancer eventually succumb to the disease despite the fact that some patients respond initially to chemotherapy. Thus, identifying molecular mechanisms responsible for chemotherapy resistance will help design novel strategies to treat gastric cancer. In this study, we discovered that residual cancer cells following 5Fu treatment have elevated expression of hedgehog(Hg) target genes GLI1 and GLI2, suggestive of Hh signaling activation. Hh signaling, a pathway essential for embryonic development, is an important regulator for putative cancer stem cells/residual cancer cells. We found that high GLI1/GLI2 expression is associated with some features of putative cancer stem cells, such as increased side population. We demonstrated that GLI2 knockdown sensitized gastric cancer cells to 5Fu treatment, decreased ABCG2 expression, and reduced side population. Elevated GLI2 expression is also associated with an increase in tumor sphere size, another marker for putative cancer stem cells. We believe that GLI2 regulates putative cancer stem cells through direct regulation of ABCG2. ABCG2 can rescue the GL12 shRNA effects in 5Fu response, tumor sphere formation and side population changes, suggesting that ABCG2 is an important mediator for GLI2-associated 5Fu resistance. The relevance of our studies to gastric cancer patient care is reflected by our discovery that high GLI1/GLI2/ABCG2 expression is associated with a high incidence of cancer relapse in two cohorts of gastric cancer patients who underwent chemotherapy(containing 5Fu). Taken together,we have identified a molecular mechanism by which gastric cancer cells gain 5Fu resistance. | Beiqin Yu Dongsheng Gu Xiaoli Zhang Bingya Liu Jingwu Xie | 2017 | Journal of Genetics and Genomics2017，44，8： | 9 |

| 8 | Paddy System with a Hybrid Rice Enhances Cyanobacteria Nostoc and Increases N2 Fixation显示文摘Biological nitrogen (N) fixation (BNF) plays a significant role in maintaining soil fertility in paddy field ecosystems. Rice variety influences BNF, but how different rice varieties regulate BNF and associated diazotroph communities has not been quantified. Airtight, field-based 15N2-labelling grow th chamber experiments were used to assess the BNF capac 辻 y of different rice varie ties. In addition, both the 16S rRNA and nifH genes were sequenced to assess the influence of different rice varieties on bacterial and diazotrophic communities in paddy soils. After subjecting a rice-soil system to 74 d of continuous airtight, field-based 15N2 labelling in pots in a growth chamber, the amounts of fixed N were 22.3 and 38.9 kg ha^-1 in inbred japonica (W23) and hybrid indica (IIY) rice cultivars plan ted in the rice-soil systems, respectively, and only 1%—2.5% of the fixed N was allocated to the rice plants and weeds. A greater abundance of diazotrophs was found in the surface soil (0-1 cm) under IIY than under W23. Sequencing of the 16S rRNA gene showed significantly greater abundances of the cyanobacterial genera Nostoc, Anabaena, and Cylindrospermum under IIY than under W23. Sequencing of the nifH gene also showed a significantly greater abundance of Nostoc under IIY than under W23. These results indicate that the hybrid rice cultivar (IIY) promoted BNF to a greater extent than the inbred rice cultivar (W23) and that the increase in BNF might have been due to the enhanced heterocystous cyanobacteria Nostoc. | MA Jing BEI Qicheng WANG Xiaojie LIU Gang Georg CADISCH LIN Xingwu ZHU Jianguo SUN Xiaoli XIE Zubin | 2019 | Pedosphere2019，29，3： | 7 |

| 11 | Research Progress in Catalytic Cracking Reaction of Tetralin and Decalin显示文摘The integrated catalytic hydrogenation and catalytic cracking process has been gradually adopted by refineries to satisfy the requirements for manufacture of light and clean petroleum products. To explore the reaction laws of hydrogenated aromatics in hydrotreated oil, the catalytic cracking reaction laws of hydrogenated aromatics have been reviewed by taking tetralin and decalin as examples of different degrees of hydrogenated aromatics. Moreover, the reaction mechanism of tetralin and decalin has been analyzed emphatically. The effects of zeolite pore structure, acid properties and process parameters on reaction laws have been analyzed carefully. It is considered that the catalytic cracking performance of hydrogenated aromatics with different hydrogen saturation degrees is quite different. It is necessary to control the hydrogenation depth, optimize the hydrocarbon composition of catalytic cracking feed materials for maximizing the yield of target products. | Li Xiao Xie Chaogang Wei Xiaoli | 2017 | China Petroleum Processing & Petrochemical Technology2017，19，4： | 5 |
| 12 | Controlled growth and photoluminescence of highly oriented arrays of ZnO nanocones with different diameters显示文摘Large-scale oriented ZnO nanocone arrays were directly grown on zinc substrate through a hydro-thermal reaction of Zn foil with aqueous butylamine solution(3 mol/L) at 100-180 ℃ for 12 h.The syn-thesized products were characterized with X-ray diffraction,Raman spectrum,scanning electron mi-croscopy and transmission electron microscopy.The results showed that the ZnO nanocones were single crystalline with the wurtzite structure and grown along the [0001] direction.The diameter of nanocones is decreased with increasing the reaction temperature.A possible growth mechanism was also proposed to account for the formation of the ZnO nanocone arrays.The photoluminescence spectra of the ZnO nanocone arrays were studied at room temperature,two UV emission bands at 377 and 396 nm assigned to free exciton emission and exciton-exciton collision,respectively,and phonon replicas associated with 2-E2 phonon were observed in the PL spectra. | MA JunHu YANG HeQing SONG YuZhe LI Li XIE XiaoLi LIU RuiNi WANG LinFang | 2009 | Science China(Technological Sciences)2009，52，5： | 4 |

| 14 | Cold spray additive manufacturing of Invar 36 alloy:microstructure,thermal expansion and mechanical properties显示文摘In this work,the Invar 36 alloys were manufactured using cold spray(CS)additive manufacturing technique.The systematic investigations were made on the microstructural evolution,thermal expansion and mechanical properties under as-sprayed(AS)and heat-treated(HT)conditions.XRD(X-ray diffraction)and ICP-AES(inductively coupled plasma atomic emission spectroscopy)analyses show that no phase transformation,oxidation,nor element content change have occurred.The X-ray computed tomography(XCT)exhibited a near fully dense structure with a porosity of 0.025%in the helium-produced sample under as-sprayed condition,whereas the nitrogen-produced samples produced at 5 MPa and 800℃show more irregular pore defects.He-AS sample shows a more prominent grain refinement than that of nitrogen samples due to the more extensive plastic deformation.The post heat-treatment exhibited a promoted grain growth,inter-particle diffusion,as well as the formation of annealing twins.Between25℃and 200℃,the nitrogen samples possessed lower CTE(coefficient of thermal expansion)values(1.53×10^(-6)/℃)compared with those produced by casting and laser additive manufacturing.The He-AS samples exhibited a noticeable negative CTE value between 25℃and 200℃,which may due to the significant compressive residual stress(-272 MPa)compensating its displacement with temperature increase during CTE test.The N2-HT and He-HT Invar 36 samples present a notable balance between strength and ductility.In conclusion,the CS technique can be considered as a potential method to produce the Invar36 component with high thermal and mechanical performance. | Chaoyue Chen Yingchun Xie Longtao Liu Ruixin Zhao Xiaoli Jin Shanqing Li Renzhong Huang Jiang Wang Hanlin Liao Zhongming Ren | 2021 | Journal of Materials Science & Technology2021，，13： | 4 |
| 15 | Light-triggered interfacial charge transfer and enhanced photodetection in CdSe/ZnS quantum dots/MoS_(2)mixed-dimensional phototransistors显示文摘Mix-dimensional van der Waals heterostructures(vdWHs)have inspired worldwide interests and efforts in the field of ad-vanced electronics and optoelectronics.The fundamental understanding of interfacial charge transfer is of vital import-ance for guiding the design of functional optoelectronic applications.In this work,type-Ⅱ0D-2D CdSe/ZnS quantum dots/MoS_(2)vdWHs are designed to study the light-triggered interfacial charge behaviors and enhanced optoelectronic performances.From spectral measurements in both steady and transient states,the phenomena of suppressed photolu-minescence(PL)emissions,shifted Raman signals and changed PL lifetimes provide strong evidences of efficient charge transfer at the 0D-2D interface.A series of spectral evolutions of heterostructures with various QDs overlapping concentrations at different laser powers are analyzed in details,which clarifies the dynamic competition between exciton and trion during an efficient doping of 3.9×10^(13)cm^(−2).The enhanced photoresponses(1.57×10^(4)A·W^(-1))and detectivities(2.86×10^(11)Jones)in 0D/2D phototransistors further demonstrate that the light-induced charge transfer is still a feasible way to optimize the performance of optoelectronic devices.These results are expected to inspire the basic understand-ing of interfacial physics at 0D/2D interfaces,and shed the light on promoting the development of mixed-dimensional op-toelectronic devices in the near future. | Ziwei Li Wen Yang Ming Huang Xin Yang Chenguang Zhu Chenglin He Lihui Li Yajuan Wang Yunfei Xie Zhuoran Luo Delang Liang Jianhua Huang Xiaoli Zhu Xiujuan Zhuang Dong Li Anlian Pan | 2021 | Opto-Electronic Advances2021，4，9： | 4 |
| 16 | Preventative effect of massage on gastric volvulus in infants with gastroesophageal reflux-induced pneumonia显示文摘OBJECTIVE:To study the preventative effects of massage on gastric volvulus(GV) in infants with gastroesophageal reflux(GER)-induced pneumonia.METHODS:One-hundred and eighty GV with GER-induced pneumonia inpatients were divided randomly into four groups:basic treatment 1(n =60),basic treatment 2(n = 30),massage treatment1(n = 60) and massage treatment 2(n = 30).Clinical examinations selected between groups 1 and 2were different.Radiography of the upper gastrointestinal tract using iodine-containing contrast was assessed in group 1 before and after treatment,whereas 24-h pH monitoring of the distal esophagus was assessed in group 2 before and after treatment.Symptom scores and chest radiography were assessed in all groups upon hospital admission and after procedures.Clinical effects were estimated after procedures in all groups.The prevalence of severe pneumonia among the four groups was compared.RESULTS:Massage treatment groups showed a significantly higher percentage of cure and total effect(P<0.05,P<0.01) and a lower prevalence of recurrence(but with no statistic difference,P>0.05)than basic treatment groups.Furthermore,massage treatment groups had remarkably lower scores for symptoms and signs(P<0.05,P<0.01),especially for choking on milk,than basic treatment groups.There was significant attenuation of chest inflammation(P<0.05,P<0.01),GV(P<0.05,P<0.01) and GER(P<0.05,P<0.01) in massage treatment groups compared with those in basic treatment groups.Finally,massage treatment groups demonstrated a lower prevalence of severe pneumonia than basic treatment groups(P<0.05).CONCLUSION:Massage treatment can prevent GV with GER-induced pneumonia in infants by timely correction of stomach rotation and subsequent attenuation of GER. | Yan Suqi Xiong Xiaoli Wan Qi Liu Fan Tang Jianqiao Jiang Zhixia Zhou Lishan Yuan Kai Xie Dong | 2015 | Journal of Traditional Chinese Medicine2015，35，5： | 3 |
| 17 | Diagnosis and treatment of infantile malignant solid tumors in Beijing,China:A multicenter 10-year retrospective study显示文摘Importance:Cancer is the main cause of death by disease in children.Children experience the highest incidence of cancer in the first year of life.However,there is no comprehensive registration system for children with tumors in China.Objective:To summarize the diagnosis and treatment of infant cancer and analyze the status of standardized diagnosis and management among several treatment centers in Beijing,China,thereby providing evidence to guide further clinical research.Methods:From January 1,2010 to December 31,2019,patients with newly diagnosed infantile malignant solid tumors were admitted to six large tertiary pediatric solid tumor diagnosis and treatment centers in Beijing.The epidemiology,clinical features,and therapeutic effects of tumors in these patients were analyzed retrospectively.All patients were followed up until March 31,2020.Results:In total,938 patients were enrolled in this study.There were 530 boys(56.5%)and 408 girls(43.5%);the median age was 6.0 months(range,0-12.0 months).The three most common tumors were retinoblastoma in 366 patients(39.0%),neuroblastoma in 266 patients(28.4%),hepatoblastoma in 133 patients(14.2%),and central nervous system tumors in 52 patients(5.5%).The estimated 5-year overall survival rate was 81.3%±1.8%,and the 5-year event-free survival rate was 71.8%±2.9%.The 5-year overall survival rates of non-rhabdomyosarcoma soft tissue sarcoma,neuroblastoma,and retinoblastoma were 100%,88%±2.2%,and 86.9%±2.1%,respectively.The 5-year event-free survival rates were 81.1%±2.7%for neuroblastoma,81.6%±9.8%for non-rhabdomyosarcoma soft tissue sarcoma,and 72.7%±14.1%for extracranial malignant germ cell tumors.Interpretation:The three most common infantile malignant solid tumors were retinoblastoma,neuroblastoma,and hepatoblastoma.Multidisciplinary combined diagnosis and treatment is needed for infantile tumors. | Mei Jin Zhi Tian Yao Xie Zhaoxia Zhang Miao Li YaxiongYu Weiling Zhang Junyang Zhao Huanmin Wang Qi Zeng Long Li Ming Ge Ning Sun Xiaolun Zhang Jian Gong Wanshui Wu Rong Liu Weihong Zhao Dongsheng Huang Xiaoli Ma | 2020 | Pediatric Investigation2020，4，3： | 3 |

| 19 | Tumor shrinkage by cyclopamine tartrate through inhibiting hedgehog signaling显示文摘The link of hedgehog (Hh) signaling activation to human cancer and synthesis of a variety of Hh signaling inhibitors raise great expectation that inhibiting Hh signaling may be effective in human cancer treatment. Cyclopamine (Cyc), an alkaloid from the Veratrum plant, is a specific natural product inhibitor of the Hh pathway that acts by targeting smoothened (SMO) protein. However, its poor solubility, acid sensitivity, and weak potency relative to other Hh antagonists prevent the clinical development of Cyc as a therapeutic agent. Here, we report properties of cyclopamine tartrate salt (CycT) and its activities in Hh signaling-mediated cancer in vitro and in vivo. Unlike Cyc, CycT is water soluble (5-10 mg/mL). The median lethal dose (LD50) of CycT was 62.5 mg/kg body weight compared to 43.5 mg/kg for Cyc, and the plasma half-life (T1/2) of CycT was not significantly different from that of Cyc. We showed that CycT had a higher inhibitory activity for Hh signaling-dependent motor neuron differentiation than did Cyc (IC50 = 50 nmol/L for CycT vs. 300 nmol/L for Cyc). We also tested the antitumor effectiveness of these Hh inhibitors using two mouse models of basal cell carcinomas (K14cre:Ptch1neo/neo and K14cre:SmoM2YFP). After topical application of CycT or Cyc daily for 21 days, we found that all CycT-treated mice had tumor shrinkage and decreased expression of Hh target genes. Taken together, we found that CycT is an effective inhibitor of Hh signaling-mediated carcinogenesis. | Qipeng Fan Dongsheng Gu Miao He Hailan Liu Tao Sheng Guorui Xie Ching-xin Li Xiaoli Zhang Brandon Wainwright Arash Garrossian Massoud Garrossian Dale Gardner Jingwu Xie | 2011 | Chinese Journal of Cancer2011，30，7： | 3 |
| 20 | Plasmonically engineered light-matter interactions in Aunanoparticle/MoS_(2) heterostructures for artificial optoelectronic synapse显示文摘Optoelectronic synaptic elements are emerging functional devices for the vigorous development of advanced neuromorphic computing technology in the post-Moore era.However,optoelectronic devices based on transition metal dichalcogenides(TMDs)are limited to their poor mobilities and weak light-matter interactions,which still hardly exhibit superior device performances in the application of artificial synapses.Here,we demonstrate the successful fabrication of Au nanoparticle-coupled MoS_(2)heterostructures via chemical vapor deposition(CVD),where the light absorption of MoS_(2)is greatly enhanced and engineered by plasmonic effects.Hot electrons are excited from Au nanoparticles,and then injected into MoS_(2)semiconductors under the light illumination.The plasmonically-engineered photo-gating effect at the metal-semiconductor junction is demonstrated to create optoelectronic devices with excellent synaptic behaviors,especially in ultra-sensitive excitatory postsynaptic current(EPSC,9.6×10^(-3)nA@3.4 nW·cm^(-2)),ultralow energy consumption(34.7 pJ),long-state retention time(>1,000 s),and tunable synaptic plasticity transitions.The material system of Au-nanoparticles coupled TMDs presents unique advantages for building artificial synapses,which may lead the future development of neuromorphic electronics in optical information sensing and learning. | Zhuoran Luo Yunfei Xie Ziwei Li Yajuan Wang Lihui Li Ziyu Luo Chenguang Zhu Xin Yang Ming Huang Jianhua Huang Delang Liang Xiaoli Zhu Dong Li Anlian Pan | 2022 | Nano Research2022，15，4： | 3 |
