| 1 | Inhibiting effect of antisense oligonucleotides phosphorthioate on gene expression of TIMP-1 in rat liver fibrosis显示文摘AIM To observe the inhibition of antisenseoligonucleotides (asON) phosphorthioate to thetissue inhibitors metalloproteinase-1 (TIMP-1)gene and protein expression in the liver tissue ofimmunologically induced hepatic fibrosis rats.The possibility of reversing hepatic fibrosisthrough gene therapy was observed.METHODS Human serum albumin (HSA) wasused to attack rats, as hepatic fibrosis model, inwhich asONs were used to block the gene andprotein expressing TIMP-1. According to theanalysis of modulator, structure protein, codingseries of TIMP-1 genome, we designed fourdifferent asONs. These asONs were injected intothe hepatic fibrosis models through coccygealvein. The results was observed by RT-PCR formeasuring TIMP-1 mRNA expression,immunohistochemistry and in situ hybridizationfor collagen Ⅰ, Ⅲ, special staining of collagenfiber, and electron microscopic examination.RESULTS Hepatic fibrosis could last within 363days in our modified model. The expressinglevel of TIMP-1 was high during hepatic fibrosisprocess. It has been proved by theimmunohistochemical and the electronmicroscopic examination that the asONphosphorthioate of TIMP-1 could exactly expressin vivo. The effect of colchicine wasdemonstrated to inhibit the expressing level ofmRNA and the content of collagen Ⅰ, Ⅲ in theliver of experimental hepatic fibrosis rats.However, the electron microscopy research andthe pathologic grading of hepatic fibrosisshowed that there was no significant differencebetween the treatment group and the modelgroup (P>0.05).CONCLUSION The experimental rat model ofhepatic fibrosis is one of the preferable modelsto estimate the curative effect of anti-hepaticfibrosis drugs. The asON phosphorthioate ofTIMP-1 could block the gene and proteinexpression of TIMP-1 in the liver of experimentalhepatic fibrosis rats at the mRNA level. It ispossible to reverse hepatic fibrosis, and it isexpected to study a new drug of anti-hepaticfibrosis on the genetic level. Colchicine has verylimited therapeutic effect on hepatic fibrosis,furthermore, its toxicity and side effects areobvious. | Qing He Nie Yong Qian Cheng Yu Mei Xie Yong Xing Zhou Yi Zhan Cao The Center of Infectious Disease Diagnosis and Treatment of PLA,Tangdu Hospital,Forth Military Medical University,Xi’an 710038,Shaanxi Province,ChinaDr,Qing He Nie graduated from Qinghai Medical College as a doctor in 1983,got master degree at Beijing 302 Army Hospital in 1993,got doctor degree at the Third Military Medical University in 1998,engaged in postdoctoral research at the Fourth Military Medical University from 1998 to 2000,now an associate professor,specialized in clinical and experimental research of infectious diseases,had more than 90 papers published,coauthor of ten books,first author of one book. | 2001 | World Journal of Gastroenterology2001，7，3： | 73 |

| 3 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 4 | Assessing the health risk of heavy metals in vegetables to the general population in Beijing,China显示文摘A systematic survey of As, Cd, Cr, Cu, Ni, Pb and Zn concentrations in vegetables from 416 samples (involving 100 varieties) in Beijing was carried out for assessing the potential health risk to local inhabitants. The results indicated that the metal concentrations in vegetables ranged from < 0.001 to 0.479 μg/g fresh weight (fw) (As), < 0.001 to 0.101 μg/g fw (Cd), < 0.001 to 1.04 μg/g fw (Cr), 0.024 to 8.25 μg/g fw (Cu), 0.001 to 1.689 μg/g fw (Ni), < 0.001 to 0.655 μg/g fw (Pb) and 0.01 to 25.6 μg/g fw (Zn), with average concentrations of 0.013, 0.010, 0.023, 0.51, 0.053, 0.046 and 2.55 μg/g fw, respectively. The results showed that the concentrations of As, Cr, Cu, Cd, Pb and Ni in vegetables from open-fields were all significantly higher than those grown in greenhouses. In addition, in local-produced vegetables, all HMs except Zn were significantly higher than those in provincial vegetables. The estimated daily intake (EDI) of As, Cd, Cr, Cu, Ni, Pb and Zn from vegetables was 0.080, 0.062, 0.142, 3.14, 0.327, 0.283 and 15.7 μg/(kg body weight (bw)·d) for adults, respectively. Arsenic was the major risk contributor for inhabitants since the target hazard quotient based on the weighted average concentration (THQw) of arsenic amounted to 44.3% of the total THQ (TTHQ) value according to average vegetable consumption. The TTHQ was lower than 1 for all age groups, indicating that it was still safe for the general population of Beijing to consume vegetables. | SONG Bo LEI Mei CHEN Tongbin ZHENG Yuanming XIE Yunfeng LI Xiaoyan GAO Ding | 2009 | Journal of Environmental Sciences2009，21，12： | 45 |
| 5 | Remote sensing imagery in vegetation mapping: a review显示文摘Aims Mapping vegetation through remotely sensed images involves various considerations,processes and techniques.Increasing availability of remotely sensed images due to the rapid advancement of remote sensing technology expands the horizon of our choices of imagery sources.Various sources of imagery are known for their differences in spectral,spatial,radioactive and temporal characteristics and thus are suitable for different purposes of vegetation mapping.Generally,it needs to develop a vegetation classification at first for classifying and mapping vegetation cover from remote sensed images either at a community level or species level.Then,correlations of the vegetation types(communities or species)within this classification system with discernible spectral characteristics of remote sensed imagery have to be identified.These spectral classes of the imagery are finally translated into the vegetation types in the image interpretation process,which is also called image processing.This paper presents an overview of how to use remote sensing imagery to classify and map vegetation cover.Methods Specifically,this paper focuses on the comparisons of popular remote sensing sensors,commonly adopted image processing methods and prevailing classification accuracy assessments.Important findings The basic concepts,available imagery sources and classification techniques of remote sensing imagery related to vegetation mapping were introduced,analyzed and compared.The advantages and limitations of using remote sensing imagery for vegetation cover mapping were provided to iterate the importance of thorough understanding of the related concepts and careful design of the technical procedures,which can be utilized to study vegetation cover from remote sensed images. | Yichun Xie Zongyao Sha Mei Yu | 2008 | Journal of Plant Ecology2008，1，1： | 39 |
| 6 | 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 |
| 7 | Circular RNA ciRS-7 promotes the proliferation and metastasis of pancreatic cancer by regulating miR-7-mediated EGFR/STAT3 signaling pathway显示文摘Background: Pancreatic ductal adenocarcinoma(PDAC) is the most deadly type of tumor, and its pathogenesis remains unknown. Circular RNAs(circRNAs) may be functional and bind to micro RNAs and consequently, influence the activity of targeted mRNAs. Recent researches indicate that one circRNA, ciRS-7, acts as a sponge of miR-7 and thus, inhibits its activity. It is well known that miR-7 is a cancer suppressor in many cancers. However, the relationship between ciRS-7 and miR-7, and the role of ciRS-7 in PDAC, remains to be elucidated. Methods: miR-7 and ciRS-7 expression in 41 pairs of PDAC tumors and their paracancerous tissues were detected by quantitative reverse transcription polymerase chain reaction(qRT-PCR). The relationships between their expression levels and clinicopathological features in PDAC tissues were assessed. The relationship between miR-7 and ciRS-7 was also assessed by Spearman’s correlation. We also used cell lines to evaluate the role of ciRS-7 in cell line behavior. The ciRS-7 interfere RNA(si RNA) and its empty vector were transfected into PDAC cells. PDAC cells proliferation and invasion abilities were detected by MTT assay and invasion analysis. The expression of proteins was assessed by Western blotting. Results: ciRS-7 expression was significantly higher in PDAC tissues than paracancerous tissues( P = 0.002). However, miR-7 expression showed the opposite trend( P = 0.048). Moreover, ciRS-7 expression was inversely correlated with miR-7 in PDAC( r s =-0.353, P = 0.023). ciRS-7 expression was also significantly elevated in venous invasion(3.72 ± 2.93 vs. 2.14 ± 1.26;P = 0.028) and lymph node metastasis(4.19 ± 2.75 vs. 2.32 ± 1.90;P = 0.016) in PDAC patients. Furthermore, ciRS-7 knockdown suppressed cell proliferation and invasion of PDAC cells( P < 0.05), and the downregulation of ciRS-7 resulted in miR-7 overexpression and subsequent inhibition of epidermal growth factor receptor(EGFR) and signal transducer and activator of transcription 3(STAT3). Conclusions: Circular RNA ciRS-7 plays an oncogene role in PDAC, partly by targeting miR-7 and regulating the EGFR/STAT3 signaling pathway. | Lei Liu Fu-Bao Liu Mei Huang Kun Xie Qing-Song Xie Chen-Hai Liu Min-Jing Shen Qiang Huang | 2019 | Hepatobiliary & Pancreatic Diseases International2019，18，6： | 21 |
| 8 | Genome-wide Transcription Factor Gene Prediction and their Expressional Tissue-Specificities in Maize显示文摘Transcription factors (TFs) are important regulators of gene expression. To better understand TF-encoding genes in maize (Zea mays L.), a genome-wide TF prediction was performed using the updated B73 reference genome. A total of 2 298 TF genes were identified, which can be classified into 56 families. The largest family, known as the MYB superfamily, comprises 322 MYB and MYB-related TF genes. The expression patterns of 2014 (87.64%) TF genes were examined using RNA-seq data, which resulted in the identification of a subset of TFs that are specifically expressed in particular tissues (including root, shoot, leaf, ear, tassel and kernel). Similarly, 98 kernel-specific TF genes were further analyzed, and it was observed that 29 of the kernel-specific genes were preferentially expressed in the early kernel developmental stage, while 69 of the genes were expressed in the late kernel developmental stage. Identification of these TFs, particularly the tissue-specific ones, provides important information for the understanding of development and transcriptional regulation of maize. | Yi Jiang Biao Zeng Hainan Zhao Mei Zhang Shaojun Xie Jinsheng Lai | 2012 | Journal of Integrative Plant Biology2012，54，9： | 20 |
| 9 | Minimally invasive surgery alone compared with intensity-modulated radiotherapy for primary stage I nasopharyngeal carcinoma显示文摘Background:The National Comprehensive Cancer Network guidelines recommend intensity-modulated radiotherapy(IMRT)as the primary curative treatment for newly diagnosed nasopharyngeal carcinoma(NPC),but the radiation-related complications and relatively high medical costs remain a consequential burden for the patients.Endoscopic nasopharyngectomy(ENPG)was successfully applied in recurrent NPC with radiation free and relatively low medical costs.In this study,we examined whether ENPG could be an effective treatment for localized stage I NPC.Methods:Ten newly diagnosed localized stage I NPC patients voluntarily received ENPG alone from June 2007 to September 2017 in Sun Yat-sen University Cancer Center.Simultaneously,the data of 329 stage I NPC patients treated with IMRT were collected and used as a reference cohort.The survival outcomes,quality of life(QOL),and medical costs between two groups were compared.Results:After a median follow-up of 59.0 months(95%CI 53.4-64.6),no death,locoregional recurrence,or distant metastasis was observed in the 10 patients treated with ENPG.The 5-year overall survival,local relapse-free survival,regional relapse-free survival,and distant metastasis-free survival among the ENPG-treated patients was similar to that among the IMRT-treated patients(100%vs.99.1%,100%vs.97.7%,100%vs.99.0%,100%vs.97.4%,respectively,P>0.05).In addition,compared with IMRT,ENPG was associated with decreased total medical costs($4090.42±1502.65 vs.$12620.88±4242.65,P<0.001)and improved QOL scores including dry mouth(3.3±10.5 vs.34.4±25.8,P<0.001)and sticky saliva(3.3±10.5 vs.32.6±23.3,P<0.001).Conclusions:ENPG alone was associated with promising long-term survival outcomes,low medical costs,and satisfactory QOL and might therefore be an alternative strategy for treating newly diagnosed localized stage I NPC patients who refused radiotherapy.However,the application of ENPG should be prudent,and prospective clinical tri-als were needed to further verify the results. | You-Ping Liu Xing Lv Xiong Zou Yi-Jun Hua Rui You Qi Yang Le Xia Shao-Yan Guo Wen Hu Meng-Xia Zhang Si-Yuan Chen Mei Lin Yu-Long Xie Li-Zhi Liu Rui Sun Pei-Yu Huang Wei Fan Xiang Guo Ming-Huang Hong Ming-Yuan Chen | 2019 | Cancer Communications2019，39，1： | 17 |

| 11 | Microstructure and mechanical properties of BFe10 cupronickel alloy tubes fabricated by a horizontal continuous casting with heating-cooling combined mold technology显示文摘A new horizontal continuous casting method with heating-cooling combined mold (HCCM) technology was explored for fabri-cating high-quality thin-wall cupronickel alloy tubes used for heat exchange pipes. The microstructure and mechanical properties of BFe10 cupronickel alloy tubes fabricated by HCCM and traditional continuous casting (cooling mold casting) were comparatively investigated. The results show that the tube fabricated by HCCM has smooth internal and external surfaces without any defects, and its internal and external surface roughnesses are 0.64 μm and 0.85 μm, respectively. The tube could be used for subsequent cold processing without other treatments such as surface planning, milling and acid-washing. This indicates that HCCM can effectively reduce the process flow and improve the pro-duction efficiency of a BFe10 cupronickel alloy tube. The tube has columnar grains along its axial direction with a major casting texture of {012}<62-1 >. Compared with cooling mold casting (δ = 36.5%), HCCM can improve elongation (δ = 46.3%) by 10% with a slight loss of strength, which indicates that HCCM remarkably improves the cold extension performance of a BFe10 cupronickel alloy tube. | Jun Mei Xin-hua Liu Jian-xin Xie | 2012 | International Journal of Minerals,Metallurgy and Materials2012，19，4： | 13 |

| 13 | A curative-intent endoscopic surgery for postradiation nasopharyngeal necrosis in patients with nasopharyngeal carcinoma显示文摘Background:Postradiation nasopharyngeal necrosis(PRNN)is a severe complication after radiotherapy in patients with nasopharyngeal carcinoma(NPC),which can severely affect the quality of life and threaten the patient’s life.Only 13.4%-28.6%of patients can be cured by traditional repeated endoscopic debridement.Here,we introduced an innovative curative-intent endoscopic surgery for PRNN patients and evaluated its clinical efficacy.Methods:Clinical data of 72 PRNN patients who underwent radical endoscopic necrectomy,followed by reconstruc-tion using a posterior pedicle nasal septum and floor mucoperiosteum flap were analyzed to determine the efficacy of this surgery.The endpoints were complete re-epithelialization of the nasopharyngeal defect,relief of headache,and overall survival(OS).Results:All surgeries were successfully performed without any severe postoperative complications or death.The median value of numeric rating scales of pain decreased from 8 before surgery to 0 after surgery(P<0.001).Fifty-one patients(70.8%)achieved complete re-epithelialization of the nasopharyngeal defect.The number of cycles of radiotherapy(odds ratio[OR],7.254;95%confidence interval[CI]1.035-50.821;P=0.046),postoperative pathological result(OR,34.087;95%CI 3.168-366.746;P=0.004),and survival status of flap(OR,261.179;95%CI 17.176-3971.599;P<0.001)were independent risk factors of re-epithelialization of the nasopharyngeal defects.Postoperative patho-logical result(hazard ratio[HR],5.018;95%CI 1.970-12.782;P=0.001)was an independent prognostic factor for OS.The 2-year OS rate of the entire cohort was 77.9%.Conclusion:Curative-intent endoscopic necrectomy followed by construction using the posterior pedicle nasal septum and floor mucoperiosteum flap is a novel,safe,and effective treatment of PRNN in patients with NPC. | Xiong Zou Shun-Lan Wang You-Ping Liu Yan-Ling Liu Ru-Hai Zou Yi-Nuan Zhang Rui You Qi Yang Yu-Long Xie Mei Lin Pei-Yu Huang Rou Jiang Meng-Xia Zhang Chao-Nan Qian Hai-Qiang Mai Ling Guo Ming-Huang Hong Ming-Yuan Chen | 2018 | Cancer Communications2018，38，1： | 11 |
| 14 | Hispidulin induces ER stress-mediated apoptosis in human hepatocellular carcinoma cells in vitro and in vivo by activating AMPK signaling pathway显示文摘Hispidulin (4’,5,7-trihydroxy-6-methoxyflavone) is a phenolic ?avonoid isolated from the medicinal plant S. involucrata, which exhibits anti-neoplastic activity against several types of cancer. However, the mechanism underlying its anti-cancer activity against hepatocellular carcinoma (HCC) has not been fully elucidated. In this study, we investigated whether and how hispidulin-induced apoptosis of human HCC cells in vitro and in vivo. We showed that hispidulin (10, 20 μmol/L) dose-dependently inhibited cell growth and promoted apoptosis through mitochondrial apoptosis pathway in human HCC SMMC7721 cells and Huh7 cells. More importantly, we revealed that its pro-apoptotic effects depended on endoplasmic reticulum stress (ERS) and unfolded protein response (UPR), as pretreatment with salubrinal, a selective ERS inhibitor, or shRNA targeting a UPR protein CHOP effectively abrogated hispidulin-induced cell apoptosis. Furthermore, we showed that hispidulin-induced apoptosis was mediated by activation of AMPK/mTOR signaling pathway as pretreatment with Compound C, an AMPK inhibitor, or AMPK-targeting siRNA reversed the pro-apoptotic effect of hispidulin. In HCC xenograft nude mice, administration of hispidulin (25, 50 mg/kg every day, ip, for 27 days) dose-dependently suppressed the tumor growth, accompanied by inducing ERS and apoptosis in tumor tissue. Taken together, our results demonstrate that hispidulin induces ERS-mediated apoptosis in HCC cells via activating the AMPK/mTOR pathway. This study provides new insights into the anti-tumor activity of hispidulin in HCC. | Mei Han Hui Gao Jing Xie Yin-ping Yuan Quan Yuan Ming-quan Gao Kai-li Liu Xue-hong Chen Yan-tao Han Zhi-wu Han | 2019 | Acta Pharmacologica Sinica2019，40，5： | 9 |
| 15 | Porphyromonas gingivalis disrupts vascular endothelial homeostasis in a TLR-NF-κB axis dependent manner显示文摘Cardiovascular disease is still the leading cause of mortality worldwide.Vascular endothelial dysfunction is viewed as the initial step of most cardiovascular diseases.Many studies have indicated that periodontal pathogens,especially Porphyromonas gingivalis,are closely correlated with vascular endothelial homeostasis,but the function of P.gingivalis and the underlying mechanisms are still elusive.To illuminate the effects and elucidate the mechanisms of P.gingivalis on endothelial structural integrity,we developed P.gingivalis infection models in vivo and in vitro.Endothelial cell proliferation,differentiation and apoptosis were detected.Here,we showed that P.gingivalis can impair endothelial integrity by inhibiting cell proliferation and inducing endothelial mesenchymal transformation and apoptosis of endothelial cells,which reduce the cell levels and cause the endothelium to lose its ability to repair itself.A mechanistic analysis showed that TLR antagonist or NF-κB signalling inhibitor can largely rescue the damaged integrity of the endothelium caused by P.gingivalis,suggesting that TLR-NF-κB signalling plays a vital role in vascular endothelial homeostasis destroyed by P.gingivalis.These results suggest a potential intervention method for the prevention and treatment of cardiovascular disease. | Mengru Xie Qingming Tang Shaoling Yu Jiwei Sun Feng Mei Jiajia Zhao Lili Chen | 2020 | International Journal of Oral Science2020，12，3： | 9 |
| 16 | Advances in biomaterials and regenerative medicine for primary ovarian insufficiency therapy显示文摘Primary ovarian insufficiency(POI)is an ovarian dysfunction that affects more than 1%of women and is characterized by hormone imbalances that afflict women before the age of 40.The typical perimenopausal symptoms result from abnormal levels of sex hormones,especially estrogen.The most prevalent treatment is hormone replacement therapy(HRT),which can relieve symptoms and improve quality of life.However,HRT cannot restore ovarian functions,including secretion,ovulation,and fertility.Recently,as part of a developing field of regenerative medicine,stem cell therapy has been proposed for the treatment of POI.Thus,we recapitulate the literature focusing on the use of stem cells and biomaterials for POI treatment,and sum up the underlying mechanisms of action.A thorough understanding of the work already done can aid in the development of guidelines for future translational applications and clinical trials that aim to cure POI by using regenerative medicine and biomedical engineering strategies. | Sichen Zhang Dashuai Zhu Xuan Mei Zhenhua Li Junlang Li Mengjie Xie Halle Jiang Williams Lutz Shaowei Wang Ke Cheng | 2021 | Bioactive Materials2021，6，7： | 9 |
| 17 | Clinical features of seizures after cerebral venous sinus thrombosis and its effect on outcome among Chinese Han population显示文摘background and purpose Clinical features of epileptic seizures after cerebral venous sinus thrombosis(CVST)among Chinese patients are not known,and it is still controversial whether seizures would affect the outcome of CVST.Methods In a Chinese hospital-based study of consecutive patients with CVST between 2003 and 2015,we described the clinical features of seizures and determined the predictors of seizure onset using multivariable logistic regression analysis.We also compared the in-hospital case-fatality and short-term functional outcome(modified Rankin Scale(mRS)at discharge)in patients with versus without seizures using ordinal regression analysis.results Among 151 patients with CVST,52(34.4%)presented seizures,of which 42(80.8%)were generalised seizures.Male gender(OR 6.32,95% CI 2.06 to 19.35,p=0.001),motor deficits(OR 4.89,95% CI 1.52 to 15.68,p=0.008),intracerebral haemorrhage(OR 3.93,95% CI 1.16 to 13.26,p=0.027),cerebral infarction(OR 3.78,95% CI 1.15 to 12.36,p=0.029)and superior sagittal sinus thrombosis(OR 3.38,95% CI 91.16 to 9.86,p=0.026)were independent predictors for seizures.The overall in-hospital case-fatality rate was 2.0%(3/151),and 21(13.9%)had mRS>2 at discharge.Compared with patients without seizures,patients with seizures were more likely to have a worse outcome(p=0.02)at discharge,independent of age,gender,clinical presentation,clot burden and presence of parenchymal lesions.conclusions In Chinese Han patients,compared with patients without seizures,patients with seizures after CVST had a worse outcome.Risk factors such as male gender,paresis,parenchymal lesion and superior sagittal sinus thrombosis were independently associated with seizure onset after CVST.Generalised seizure was the main form of seizures after CVST,which was obviously different to seizures after strokes of arterial origin. | Hongyan Ding Yanan Xie Linxin Li Heling Chu Yuping Tang Qiang Dong Mei Cui | 2017 | Stroke & Vascular Neurology2017，2，4： | 8 |
| 18 | Serum 25(OH)D and Lipid Levels in Chinese Obese and Normal Weight Males before and after Oral Vitamin D Supplementation显示文摘Objective To study the effect of oral vitamin D(VD) supplementation on VD status and serum lipid in Chinese obese and healthy normal-weightmen.Methods Twenty-one obese men with their body mass index(BMI)>28 kg/m2served as an obese group and 22 healthy normal-weight men with their BMI<24 kg/m2served as a control group in this study.After they were given 50 000 IU of oral VD,once a week for 8 weeks,the serum25-hydroxyvitamin D [25(OH)D] concentration was measured with an enzyme-immunoassay kit.Results After oral VD supplementation,the serum 25(OH)D concentration significantly increased from46.1±9.1 nmol/L to 116.7±20.3 nmol/L in the obese subjects(P<0.01) and from 52.8±17.8 nmol/L to181.3±30.2 nmol/L in the control ones(P=0.13).The serum high-density lipoprotein cholesterol(HDL-C)level was reduced within the normal reference range in the obese group.However,no significant change was observed in the level of other serum lipids(triglycerides,total cholesterol,and low-density lipoprotein cholesterol) in either of the two groups.Conclusion The effect of high-dose oral VD supplementation is weaker on VD status in the obese group than in the control group.High-dose oral VD supplementation has no side effect on serum lipid level in obese and control groups. | ZHOU Ji Chang ZHU Yu Mei GUO Ping CHEN Zheng XIE Feng Zhu LIU Xiao Li HE Shan | 2013 | Biomedical and Environmental Sciences2013，26，10： | 8 |
| 19 | Malnutrition and Quality of Life in Chinese Cancer Patients: a Clinical Study of 23,994 Subjects显示文摘Background Malnutrition is common in patients with cancer,and can negatively impact their quality of life(QoL)and even survival.However,there is currently no large data available on the prevalence of malnutrition in Chinese cancer patients.This study evaluated the prevalence of malnutrition and the QoL of Chinese patients with locoregional,recurrent or metastatic cancer.Methods We conducted a nationwide observational,multi-center,hospital-based cross-sectional study within the Chinese Society of Nutritional Oncology(CSNO)Network.All of the patients were diagnosed with one of the following 18 different types of malignant tumors:lung cancer,gastric cancer,liver cancer,colorectal cancer,breast cancer,esophageal cancer,cervical cancer,endometrial cancer,nasopharyngeal carcinoma,malignant lymphoma,leukemia,pancreatic cancer,ovarian cancer,prostate cancer,bladder cancer,brain cancer,biliary tract malignant tumors or gastrointestinal stromal tumors.These patients were enrolled from 72 hospitals located in different regions of China.The patients’nutritional status was evaluated based on the body mass index(BMI),loss of bodyweight,laboratory measurements and patient generated-subjective global assessment(PG-SGA)scores.The cancer patients’physical status and QoL were assessed by the Karnofsky Performance Status(KPS)questionnaire and the European Organization for Research and Treatment of Cancer(EORTC)QLQ-C30 questionnaire,respectively.Results From December 2013 to April 2016,23,994 patients hospitalized for cancer treatment(such as surgery,chemotherapy or radiotherapy)were enrolled in the study.The patients included 12,494(52.9%)males and 11,124(47.1%)females.The mean age was 55.8±13.7 years.The proportions of patients in cancer stagesⅠ,Ⅱ,Ⅲ,Ⅳand uncertain were 11.5%,20.3%,27.5%,30.2%and 10.5%,respectively.Among the 23,994 inpatients,the proportions of patients who were underweight(BMI<18.5 kg/m2),normal(18.5 kg/m2 | Hong Xia Xu Chun Hua Song Zhen Ming Fu Chang Wang Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Fu Xiang Zhou Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Min Weng Qing Hua Yao Jiu Wei Cui Wei Li Han Ping Shi the Investigation on Nutrition Status and Clinical Outcome of Common Cancers(INSCOC)Group | 2021 | Journal of Nutritional Oncology2021，6，1： | 8 |
