1Autophagy and multidrug resistance in cancer显示文摘Multidrug resistance(MDR) occurs frequently after long-term chemotherapy, resulting in refractory cancer and tumor recurrence.Therefore, combatting MDR is an important issue. Autophagy, a self-degradative system, universally arises during the treatment of sensitive and MDR cancer. Autophagy can be a double-edged sword for MDR tumors: it participates in the development of MDR and protects cancer cells from chemotherapeutics but can also kill MDR cancer cells in which apoptosis pathways are inactive. Autophagy induced by anticancer drugs could also activate apoptosis signaling pathways in MDR cells, facilitating MDR reversal. Therefore, research on the regulation of autophagy to combat MDR is expanding and is becoming increasingly important. We summarize advanced studies of autophagy in MDR tumors, including the variable role of autophagy in MDR cancer cells.Ying-Jie Li Yu-He Lei Nan Yao Chen-Ran Wang Nan Hu Wen-Cai Ye Dong-Mei Zhang Zhe-Sheng Chen 2017Chinese Journal of Cancer2017,36,8:54

4D2 dissection in laparoscopic and open gastrectomy for gastric cancer显示文摘AIM: To evaluate the radicalness and safety of laparoscopic D2 dissection for gastric cancer. METHODS: Clinicopathological data from 209 patients with gastric cancer, who underwent radical gastrectomy with D2 dissection between January 2007 and February 2011, were analyzed retrospectively. Among these patients, 131 patients underwent laparoscopyassisted gastrectomy (LAG) and 78 underwent open gastrectomy (OG). The parameters analyzed included operative time, blood loss, blood transfusion, morbidity, mortality, the number of harvested lymph nodes (HLNs), and pathological stage.RESULTS: There were no significant differences in sex, age, types of radical resection [radical proximal gastrectomy (PG + D2), radical distal gastrectomy (DG + D2) and radical total gastrectomy (TG + D2)], and stages between the LAG and OG groups (P > 0.05). Among the two groups, 127 cases (96.9%) and 76 cases (97.4%) had 15 or more HLNs, respectively. The average number of HLNs was 26.1 ± 11.4 in the LAG group and 24.2 ± 9.3 in the OG group (P = 0.233). In the same type of radical resection, there were no signifi cant differences in the number of HLNs between the two groups (PG + D2: 21.7 ± 7.5 vs 22.4 ± 9.3; DG + D2: 25.7 ± 11.0 vs 22.3 ± 7.9; TG + D2: 30.9 ± 13.4 vs 29.3 ± 10.4; P > 0.05 for all comparisons). Tumor free margins were obtained in all cases. Compared with OG group, the LAG group had signifi cantly less blood loss, but a longer operation time (P < 0.001). The morbidity of the LAG group was 9.9%, which was not signifi cantly different from the OG group (7.7%) (P = 0.587). The mortality was zero in both groups. CONCLUSION: Laparoscopic D2 dissection is equivalent to OG in the number of HLNs, regardless of tumor location. Thus, this procedure can achieve the same radicalness as OG.Ming Cui lia-Di Xing Yi-Yuan Ma Zhen-Dan Yao Nan Zhang Xiang-Qian Su Wei Yang 2012World Journal of Gastroenterology2012,18,8:16
5Chinese Tuina Downregulates the Elevated Levels of Tissue Plasminogen Activator in Sciatic Nerve Injured Sprague-Dawley Rats显示文摘Objective:To elucidate the mechanism of Chinese tuina in treating sciatic nerve crush injury,and to detect the levels of tissue plasminogen activator(t PA)and plasminogen activator inhibitor-1(PAI-1),which is thought to play an important role in nerve regeneration.Methods:Thirty-two adult male Sprague-Dawley rats were subjected to sciatic nerve crush injury and 16 rats(sham-operated group)went through a sham operation.Control group was given no treatment while tuina group received tuina therapy since day 7 post-surgery.Tuina treatment was performed once a day and lasted for 20 days.The sciatic functional index was examined every 5days during the treatment session.The rats'gastrocnemius muscles were evaluated for changes in mass and immunohistochemistry techniques were performed to detect the levels of tP A and PAI-1.Results:Tuina therapy improved the motor function of sciatic nerve injured rats(P<0.05),however,it did not increase muscle volume(P<0.05).Tuina downregulated the levels of t PA and PAI-1(P<0.05).Conclusions:The present study implies that tuina treatment could accelerate rehabilitation of peripheral nerve injury.PAN Fan YU Tian-yuan Steven Wong XIAN Si-tong LU Meng-qian WU Jian-cong GAO Yu-feng LI Xiao-qin GENG Nan YAO Bin-bin 2017Chinese Journal of Integrative Medicine2017,23,8:16
6MicroRNA-663 induces immune dysregulation by inhibiting TGF-β1 production in bone marrow-derived mesenchymal stem cells in patients with systemic lupus erythematosus显示文摘Mesenchymal stem cells(MSCs)are critical for immune regulation.Although several microRNAs(miRNAs)have been shown to participate in autoimmune pathogenesis by affecting lymphocyte development and function,the roles of miRNAs in MSC dysfunction in autoimmune diseases remain unclear.Here,we show that patients with systemic lupus erythematosus(SLE)display a unique miRNA signature in bone marrow-derived MSCs(BMSCs)compared with normal controls,among which miR-663 is closely associated with SLE disease activity.MiR-663 inhibits the proliferation and migration of BMSCs and impairs BMSC-mediated downregulation of follicular T helper(Tfh)cells and upregulation of regulatory T(Treg)cells by targeting transforming growth factorβ1(TGF-β1).MiR-663 overexpression weakens the therapeutic effect of BMSCs,while miR-663 inhibition improves the remission of lupus disease in MRL/lpr mice.Thus,miR-663 is a key mediator of SLE BMSC regulation and may serve as a new therapeutic target for the treatment of lupus.Linyu Geng Xiaojun Tang Kangxing Zhou Dandan Wang Shiying Wang Genhong Yao Weiwei Chen Xiang Gao Wanjun Chen Songtao Shi Nan Shen Xuebing Feng Lingyun Sun 2019Cellular & Molecular Immunology2019,16,3:16

8Prognosis after resection for hepatitis B virus-associated intrahepatic cholangiocarcinoma显示文摘AIM:To investigate the prognostic factors after resection for hepatitis B virus(HBV)-associated intrahepatic cholangiocarcinoma(ICC) and to assess the impact of different extents of lymphadenectomy on patient survival.METHODS:A total of 85 patients with HBV-associated ICC who underwent curative resection from January 2005 to December 2006 were analyzed.The patients were classified into groups according to the extent of lymphadenectomy(no lymph node dissection,sampling lymph node dissection and regional lymph node dissection).Clinicopathological characteristics and survival were reviewed retrospectively.RESULTS:The cumulative 1-,3-,and 5-year survival rates were found to be 60 %,18 %,and 13 %,respectively.Multivariate analysis revealed that liver cirrhosis(HR = 1.875,95%CI:1.197-3.278,P = 0.008) and multiple tumors(HR = 2.653,95%CI:1.562-4.508,P < 0.001) were independent prognostic factors for survival.Recurrence occurred in 70 patients.The 1-,3-,and 5-year disease-free survival rates were 36%,3% and 0%,respectively.Liver cirrhosis(HR = 1.919,P = 0.012),advanced TNM stage(stage Ⅲ/Ⅳ)(HR = 2.027,P < 0.001),and vascular invasion(HR = 3.779,P = 0.02) were independent prognostic factors for disease-free survival.Patients with regional lymph node dissection demonstrated a similar survival rate to patients with sampling lymph node dissection.Lymphadenectomy did not significantly improve the survival rate of patients with negative lymph node status.CONCLUSION:The extent of lymphadenectomy does not seem to have influence on the survival of patients with HBV-associated ICC,and routine lymph nodedissection is not recommended,particularly for those without lymph node metastasis.Zhen-Feng Wu Xiao-Yu Wu Nan Zhu Zhe Xu Wei-Su Li Hai-Bin Zhang Ning Yang Xue-Quan Yao Fu-Kun Liu Guang-Shun Yang 2015World Journal of Gastroenterology2015,21,3:15
9The Chromosome-Based Rubber Tree Genome Provides New Insights into Spurge Genome Evolution and Rubber Biosynthesis显示文摘The rubber tree,Hevea brasiliensis,produces natural rubber that serves as an essential industrial raw material.Here,we present a high-quality reference genome for a rubber tree cultivar GT1 using single-molecule real-time sequencing(SMRT)and Hi-C technologies to anchor the~1.47-Gb genome assembly into 18 pseudochromosomes.The chromosome-based genome analysis enabled us to establish a model of spurge chromosome evolution,since the common paleopolyploid event occurred before the split of Hevea and Manihot.We show recent and rapid bursts of the three Hevea-specific LTR-retrotransposon families during the last 10 million years,leading to the massive expansion by~65.88%(~970 Mbp)of the whole rubber tree genome since the divergence from Manihot.We identify large-scale expansion of genes associated with whole rubber biosynthesis processes,such as basal metabolic processes,ethylene biosynthesis,and the activation of polysaccharide and glycoprotein lectin,which are important properties for latex production.A map of genomic variation between the cultivated and wild rubber trees was obtained,which contains~15.7 million high-quality single-nucleotide polymorphisms.We identified hundreds of candidate domestication genes with drastically lowered genomic diversity in the cultivated but not wild rubber trees despite a relatively short domestication history of rubber tree,some of which are involved in rubber biosynthesis.This genome assembly represents key resources for future rubber tree research and breeding,providing novel targets for improving plant biotic and abiotic tolerance and rubber production.Jin Liu Cong Shi Cheng-Cheng Shi Wei Li Qun-Jie Zhang Yun Zhang Kui Li Hui-Fang Lu Chao Shi Si-Tao Zhu Zai-Yun Xiao Hong Nan Yao Yue Xun-Ge Zhu Yu Wu Xiao-Ning Hong Guang-Yi Fan Yan Tong Dan Zhang Chang-Li Mao Yun-Long Liu Shi-Jie Hao Wei-Qing Liu Mei-Qi Lv Hai-Bin Zhang Yuan Liu Ge-Ran Hu-tang Jin-Peng Wang Jia-Hao Wang Ying-Huai Sun Shu-Bang Ni Wen-Bin Chen Xing-Cai Zhang Yuan-Nian Jiao Evan E.Eichler Guo-Hua Li Xin Liu Li-Zhi Gao 2020Molecular Plant2020,13,2:15
10Anti-inflammatory and Analgesic Effects of Extract from Roots and Leaves of Citrullus lanatus显示文摘Objective To study anti-inflammatory and analgesic effects of extract from the roots and leaves of Citrullus lanatus and assess their acute toxicity in animals. Methods The mouse model with ear edema induced by xylene and the rat model with paw edema or granuloma by carrageenin or cotton pellet were used for anti-inflammatory effects of the extract. Effects of the extract on analgesia was tested respectively by measuring the latency of mice licking hind foot from hot plates and by counting the times of body twisting in response to acetic acid. The acute toxicity of the extract was determined with the method of Bliss. Results The extract significantly inhibited the ear edema, granuloma hyperplasia, and paw edema. It significantly lifted the pain threshold on mouse hot-plate responses and reduced their writhing times. During the 7 d observation period in its acute toxicity assay, no apparent toxic reaction was shown and all mice survived at a dose of 87 g extract per kg body weight. Conclusion The extract could protecte mice/rates from inflammation and analgesia, and may be safe as an orally administered natural product for humans.DENG Jia-gang1, WANG Shuo2, GUO Li-cheng3, FAN Li-li1 1.

11Two new ursane-type nortriterpenes from Lonicera macranthoides and their iNOS-inhibitory activities显示文摘The flower buds of Lonicera macranthoides(Shan Yin-Hua), represent an important traditional Chinese medicine and food ingredient. A phytochemical investigation of the 70% EtOH extract of the flower buds of L. macranthoides resulted in the isolation of 12 triterpenoids(1-12), including two new ursane-type nortriterpenes, 2α, 24-dihydroxy-23-nor-ursolic acid(1) and 2α, 4α-dihydroxy-23-nor-ursolic acid(2). Their structures were established by multiple spectroscopic methods and comparison with literature data. All isolated compounds were evaluated for their anti-inflammatory effects in LPS-activated RAW264.7 cells. Compounds 1 and 2 exhibited inhibitory effects on iNOS at the concentration of 30 μmol·L^(-1).MEI Yu-Dan ZHANG Nan ZHANG Wei-Yang TANG Jin-Shan ZHOU Hua YU Yang YAO Xin-Sheng 2019Chinese Journal of Natural Medicines2019,17,1:9
12First proof-of-principle experiment with the post-accelerated isotope separator on-line beam at BRIF:measurement of the angular distribution of ^(23)Na+^(40)Ca elastic scattering显示文摘The reaction dynamics of exotic nuclei near the drip line is one of the main research topics of current interest.Elastic scattering is a useful probe for investigating the size and surface diffuseness of exotic nuclei.The development of rare isotope accelerators offers opportunities for such studies.To date,many relevant measurements have been performed at accelerators using the projectile fragmentation technique,while the measurements at accelerators using isotope separator on-line(ISOL)systems are still quite scarce.In this work,we present the first proof-of-principle experiment with a post-accelerated ISOL beam at the Beijing Radioactive Ion Beam Facility(BRIF)by measuring the angular distribution of elastic scattering for the stable nucleus^(23)Na from the doubly magic nucleus^(40)Ca at energies above the Coulomb barrier.The angular distribution measured by a silicon strip detector array in a scattering chamber using the ISOL beam at BRIF is in good agreement with that measured by the high-precision Q3 D magnetic spectrograph using the nonISOL beam at nearly the same energy.This work provides useful background for making BRIF a powerful tool for the investigation of the reaction dynamics of exotic nuclei.Wei Nan Bing Guo Cheng-Jian Lin Lei Yang Dong-Xi Wang Yang-Ping Shen Bing Tang Bao-Qun Cui Tao Ge Yin-Long Lyu Hui-Ming Jia Yun-Ju Li Chen Chen Li-Hua Chen Qi-Wen Fan Xin-Yue Li Gang Lian Jian-Cheng Liu Tian-Peng Luo Nan-Ru Ma Rui-Gang Ma Xie Ma Ying-Jun Ma Wei-Ke Nan Dan-Yang Pang You-Bao Wang Pei-Wei Wen Feng Yang Yong-Jin Yao Sheng Zeng Hao Zhang Fu-Peng Zhong Shan-Hao Zhong Zhi-Hong Li Tian-Jue Zhang Wei-Ping Liu BRIF Collaboration 2021Nuclear Science and Techniques2021,32,5:9

14Prognostic values of the integrated model incorporating the volume of metastatic regional cervical lymph node and pretreatment serum Epstein-Barr virus DNA copy number in predicting distant metastasis in patients with N1 nasopharyngeal carcinoma显示文摘Background: According to the 7 th edition of the American Joint Committee on Cancer(AJCC) staging system, over50% of patients with nasopharyngeal carcinoma(NPC) have N1 disease at initial diagnosis. However, patients with N1 NPC are relatively under-researched, and the metastasis risk of this group is not well-stratified. This study aimed to evaluate the prognostic values of gross tumor volume of metastatic regional lymph node(GTVnd) and pretreatment serum copy number of Epstein-Barr virus(EBV) DNA in predicting distant metastasis of patients with N1 NPC, and to develop an integrated prognostic model that incorporates GTVnd and EBV DNA copy number for this group of patients.Methods: The medical records of 787 newly diagnosed patients with nonmetastatic, histologically proven N1 NPC who were treated at Sun Yat-sen University Cancer Center between November 2009 and February 2012 were analyzed. Computed tomography-derived GTVnd was measured using the summation-of-area technique. Blood samples were collected before treatment to quantify plasma EBV DNA. The receiver operating characteristic(ROC) curve analysis was used to evaluate the cut-off point for GTVnd, and the area under the ROC curve was used to assess the predicted validity of GTVnd. The survival rates were assessed by Kaplan-Meier analysis, and the survival curves were compared using a log-rank test. Multivariate analysis was conducted using the Cox proportional hazard regression model.Results: The 5-year distant metastasis-free survival(DMFS) rates for patients with GTVnd > 18.9 vs.≤ 18.9 mL were82.2% vs. 93.2%(P < 0.001), and for patients with EBV DNA copy number > 4000 vs. < 4000 copies/mL were 83.5% vs.93.9%(P < 0.001). After adjusting for GTVnd, EBV DNA copy number, and T category in the Cox regression model, both GTVnd > 18.9 mL and EBV DNA copy number > 4000 copies/mL were significantly associated with poor prognosis(both P < 0.05). According to combination of GTVnd and EBV DNA copy number, all patients were divided into low-,moderate-, and high-risk groups, with the 5-year DMFS rates of 96.1,87.4, and 73.8%, respectively(P < 0.001). Multivariate analysis confirmed the prognostic value of this model for distant metastatic risk stratification(hazard ratio [HR],4.17; 95% confidence interval [CI] 2.34-7.59; P < 0.001).Conclusions: GTVnd and serum EBV DNA copy number are independent prognostic factors for predicting distant metastasis in NPC patients with N1 disease. The prognostic model incorporating GTVnd and EBV DNA copy number may improve metastatic risk stratification for this group of patients.Ji‑Jin Yao Guan‑Qun Zhou Ya‑Qin Wang Si‑Yang Wang Wang‑Jian Zhang Ya‑Nan Jin Fan Zhang Li Li Li‑Zhi Liu Zhi‑Bin Cheng Jun Ma Zhen‑Yu Qi 2017Chinese Journal of Cancer2017,36,12:9

16Effects of specific interleukin-1β-converting enzyme inhibitor on ischemic acute renal failure in murine models显示文摘Aim: To study the effect of selective interleukin-1β-converting enzyme (ICE, caspase-1) inhibitor on ischemic acute renal failure (ARF). Methods: Mouse models of ischemic ARF were treated with the specific ICE inhibitor AC-YVAD-CMK. A renal function assay and renal morphological studies were employed to estimate the renal protective effect of AC-YVAD-CMK. The survival rate of mouse models was also analyzed by a time series test. Furthermore, renal ICE activity, mature interleukin-18 (IL-18) protein expression and interferon-γ (IFN-γ) mRNA expression were also detected by fluorescent enzyme-linked immunosorbent assay (ELISA), ELISA, and semi-quantitative reverse transcription-polymerase chain reaction, respectively. Results: The levels of blood urea nitrogen (BUN) and serum creatinine (Scr) increased remarkably in the model controls compared with the sham-operated groups (P<0.01). Typical renal tubular necrosis was found in the model controls. Renal ICE activity, mature IL-18 protein expression, and IFN-纬 mRNA expression were also increased significantly in the model controls compared with the sham-operated groups. The levels of BUN and Scr in the AC-YVAD-CMK therapy group were decreased significantly compared with the untreated model controls (P<0.01). Renal tubulointerstitial lesion was also attenuated significantly (P<0.05). AC-YVAD-CMK therapy alleviated the clinical features of ARF, and increased the survival rate (P<0.01). Furthermore, AC-YVAD-CMK therapy also decreased ICE activity, mature IL-18 protein expression, and IFN-γ mRNA expression in renal tissue (P<0.05). Conclusion: The selective ICE inhibitor AC-YVAD-CMK can effectively protect the kidney from acute ischemic lesions. This protective effect is associated with decreased renal ICE activity and suppressed IL-18 maturation and IFN-γmRNA transcription.Hua-feng LIU Dong LIANG Li-ming WANG Nan ZHOU Cui-wei YAO Tao HONG De-shen TANG Xiao-wen CHEN 2005Acta Pharmacologica Sinica2005,26,11:8
17Lactulose enhances neuroplasticity to improve cognitive function in early hepatic encephalopathy显示文摘Lactulose is known to improve cognitive function in patients with early hepatic encephalopathy; however, the underlying mechanism remains poorly understood. In the present study, we investigated the behavioral and neurochemical effects of lactulose in a rat model of early hepatic encephalopathy induced by carbon tetrachloride. Immunohistochemistry showed that lactulose treatment promoted neurogenesis and increased the number of neurons and astrocytes in the hippocampus. Moreover, lactulose-treated rats showed shorter escape latencies than model rats in the Morris water maze, indicating that lactulose improved the cognitive impairments caused by hepatic encephalopathy. The present findings suggest that lactulose effectively improves cognitive function by enhancing neuroplasticity in a rat model of early hepatic encephalopathy.Nan Yang He Liu Yao Jiang Ji Zheng Dong-mei Li Chao Ji Yan-yong Liu Ping-ping Zuo 2015Neural Regeneration Research2015,10,9:8
