| 1 | Exosome and Exosomal MicroRNA: Trafficking, Sorting, and Function显示文摘Exosomes are 40–100 nm nano-sized vesicles that are released from many cell types into the extracellular space. Such vesicles are widely distributed in various body fluids. Recently,m RNAs and micro RNAs(mi RNAs) have been identified in exosomes, which can be taken up by neighboring or distant cells and subsequently modulate recipient cells. This suggests an active sorting mechanism of exosomal mi RNAs, since the mi RNA profiles of exosomes may differ from those of the parent cells. Exosomal mi RNAs play an important role in disease progression, and can stimulate angiogenesis and facilitate metastasis in cancers. In this review, we will introduce the origin and the trafficking of exosomes between cells, display current research on the sorting mechanism of exosomal mi RNAs, and briefly describe how exosomes and their mi RNAs function in recipient cells.Finally, we will discuss the potential applications of these mi RNA-containing vesicles in clinical settings. | Jian Zhang Sha Li Lu Li Meng Li Chongye Guo Jun Yao Shuangli Mi | 2015 | Genomics, Proteomics & Bioinformatics2015,13,1: | 162 |
| 2 | Digestive tract reconstruction using isoperistaltic jejunumlater-cut overlap method after totally laparoscopic total gastrectomy for gastric cancer: Short-term outcomes and impact on quality of life显示文摘AIM To evaluate the short-term outcomes and quality of life(Qo L) in gastric cancer patients undergoing digestive tract construction using the isoperistaltic jejunum-latercut overlap method(IJOM) after totally laparoscopic total gastrectomy(TLTG).METHODS A total of 507 patients who underwent laparoscopic gastrectomy(D2) from January 2014 to March 2016 were originally included in the study. The patients were divided into two groups to undergo digestive tract construction using either IJOM after TLTG(group T, n = 51) or Roux-en-Y anastomosis after laparoscopic-assisted total gastrectomy(LATG)(group A, n = 456). The short-term outcomes and Qo L were compared between the two groups after 1:2 propensity-score matching(PSM). We used a questionnaire to assess Qo L.RESULTS Before matching, age, sex, tumor size, tumor location, preoperative albumin and blood loss were significantly different between the two groups(P < 0.05). After PSM, the patients were well balanced in terms of their clinicopathological characteristics, although both blood loss and in-hospital postoperative days in group T were significantly lower than those in group A(P < 0.05). After matching, group T reported better Qo L in the domains of pain and dysphagia. Among the items evaluating pain and dysphagia, group T tended to report better Qo L('Have you felt pain' and 'Have you had difficulty eating solid food')(P < 0.05).CONCLUSION The IJOM for digestive tract reconstruction after TLTG is associated with reduced blood loss and less pain and dysphagia, thus improving Qo L after laparoscopic gastrectomy. | Ze-Ning Huang Chang-Ming Huang Chao-Hui Zheng Ping Li Jian-Wei Xie Jia-Bin Wang Jian-Xian Lin Jun Lu Qi-Yue Chen Long-Long Cao Mi Lin Ru-Hong Tu Ju-Li Lin | 2017 | World Journal of Gastroenterology2017,23,39: | 27 |
| 3 | Prevalence of Thyroid Nodules and Its Relationship with Iodine Status in Shanghai:a Population-based Study显示文摘Objective This study was designed to evaluate the prevalence of thyroid nodules(TNs) and its relationship with urine iodine concentrations(UICs) after the regional rapid economic growth and lifestyle changes. Methods A cross-sectional survey was conducted in the general population aged 15-69 years. A questionnaire regarding general and personal characteristics and relevant information was administered. Ultrasonography of the thyroid was performed, and serum triiodothyronine(T3), tetraiodothyronine(T4), serum thyroid stimulating hormone(TSH), free triiodothyronine(FT3), free tetraiodothyronine(FT4), thyroglobulin antibody(Tg Ab), thyroid peroxidase antibody(TPOAb), and TSH receptor antibody(TRAb) levels were measured for each individual subject. Results The prevalence rates of TNs in the whole population, females and males were 27.76%, 34.04%, and 21.60%, respectively. The prevalence of multiple nodules increased with age, whereas the prevalence peaks differed between males and females. The median UICs in the whole population and females with non-TNs were higher than those of subjects with TNs(P=0.0035, P=0.0068). The median UICs in subjects with a single TN were higher than those in subjects with multiple TNs(P=0.0164, P=0.0127). The result showed a U-shaped curve relationship between UIC and prevalence of TNs. The prevalence of TNs was the lowest when the UIC was 140-400 μg/L. Conclusion The prevalence of TNs was nearly 30% and increased with age. The relationship between UIC and prevalence of TNs is U-shaped, with an increase in risk when the UIC was <140 μg/L and >400 μg/L. Very low or high UIC levels need attention and correction. | SONG Jun ZOU Shu Rong GUO Chang Yi ZANG Jia Jie ZHU Zhen Ni MI Ming HUANG Cui Hua YU Hui Ting LU Xi RUAN Ye WU Fan | 2016 | Biomedical and Environmental Sciences2016,29,6: | 25 |
| 4 | Comparision of modified and conventional delta-shaped gastroduodenostomy in totally laparoscopic surgery显示文摘AIM:To evaluate the safety and feasibility of a modified delta-shaped gastroduodenostomy(DSG)in totally laparoscopic distal gastrectomy(TLDG).METHODS:We performed a case-control study enrolling 63 patients with distal gastric cancer(GC)undergoing TLDG with a DSG from January 2013 to June 2013.Twenty-two patients underwent a conventional DSG(Con-Group),whereas the other 41 patients underwent a modified version of the DSG(Mod-Group).The modified procedure required only the instruments of the surgeon and assistant to complete the involution of the common stab incision and to completely resect the duodenal cutting edge,resulting in an anastomosis with an inverted T-shaped appearance.The clinicopathological characteristics,surgical outcomes,anastomosis time and complications of the two groups were retrospectively analyzed using a prospectively maintained comprehensive database.RESULTS:DSG procedures were successfully completed in all of the patients with histologically complete(R0)resections,and none of these patients required conversion to open surgery.The clinicopathological characteristics of the two groups were similar.There were no significant differences between the groups in the operative time,intraoperative blood loss,extension of the lymph node(LN)dissection and number of dissected LNs(150.8±21.6 min vs 143.4±23.4 min,P=0.225for the operative time;26.8±11.3 min vs 30.6±14.8mL,P=0.157 for the intraoperative blood loss;4/18 vs3/38,P=0.375 for the extension of the LN dissection;and 43.9±13.4 vs 39.5±11.5 per case,P=0.151 for the number of dissected LNs).The anastomosis time,however,was significantly shorter in the Mod-Group than in the Con-Group(13.9±2.8 min vs 23.9±5.6min,P=0.000).The postoperative outcomes,including the times to out-of-bed activities,first flatus,resumption of soft diet and postoperative hospital stay,as well as the anastomosis size,did not differ significantly(1.9±0.6 d vs 2.3±1.5 d,P=0.228 for the time to outof-bed activities;3.2±0.9 d vs 3.5±1.3 d,P=0.295for the first flatus time;7.5±0.8 d vs 8.1±4.3 d,P=0.489 for the resumption of a soft diet time;14.3±10.6 d vs 11.5±4.9 d,P=0.148 for the postoperative hospital stay;and 30.5±3.6 mm vs 30.1±4.0 mm,P=0.730 for the anastomosis size).One patient with minor anastomotic leakage in the Con-Group was managed conservatively;no other patients experienced any complications around the anastomosis.The operative complication rates were similar in the Con-and ModGroups(9.1%vs 7.3%,P=1.000).CONCLUSION:The modified DSG,an alternative reconstruction in TLDG for GC,is technically safe and feasible,with a simpler process that reduces the anastomosis time. | Chang-Ming Huang Mi Lin Jian-Xian Lin Chao-Hui Zheng Ping Li Jian-Wei Xie Jia-Bin Wang Jun Lu | 2014 | World Journal of Gastroenterology2014,20,30: | 26 |

| 6 | Portosplenomesenteric vein thrombosis in patients with early-stage severe acute pancreatitis显示文摘AIM To investigate the incidence and risk factors of portosplenomesenteric vein thrombosis(PSMVT) in the early stage of severe acute pancreatitis(SAP).METHODS Patients with SAP in a tertiary care setting from January 2014 to December 2016 were retrospectively reviewed. All contrast-enhanced computed tomography(CT) studies were reassessed and reviewed. Clinical outcome measures were compared between SAP patients with and without PSMVT in the early stage of the disease. Univariate and multivariate logistic regression analyses were sequentially performed to assess potential risk factors for the development of PSMVT in SAP patients. A receiver operating characteristic(ROC) curve was generated for the qualifying independent risk factors.RESULTS Twenty-five of the one hundred and forty(17.86%) SAP patients developed PSMVT 6.19 ± 2.43 d after acute pancreatitis(AP) onset. PSMVT was confirmed by contrast-enhanced CT. Multivariate stepwise logistic regression analyses showed that Balthazar's CT severity index(CTSI) scores [odds ratio(OR): 2.742; 95% confidence interval(CI): 1.664-4.519; P = 0.000], hypoalbuminemia(serum albumin level < 25 g/L)(OR: 32.573; 95%CI: 2.711-391.353; P = 0.006) and gastrointestinal wall thickening(OR: 4.367, 95%CI: 1.218-15.658; P = 0.024) were independent risk factors for PSMVT developed in patients with SAP. The area under the ROC curve for Balthazar's CTSI scores was 0.777(P = 0.000), the sensitivity was 52%, and the specificity was 93% at a cut-off value of 5.5.CONCLUSION High Balthazar's CTSI scores, hypoalbuminemia and gastrointestinal wall thickening are independent risk factors for PSMVT developed in the early stage of SAP. | Ling Ding Feng Deng Chen Yu Wen-Hua He Liang Xia Mi Zhou Xin Huang Yu-Peng Lei Xiao-Jiang Zhou Yin Zhu Nong-Hua Lu | 2018 | World Journal of Gastroenterology2018,24,35: | 20 |
| 7 | Effect of temperature and oxygen on the formation of chlorobenzene as the indicator of PCDD/Fs显示文摘Sampling and analysis of polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs) are both time-consuming and expensive. In principle,real-time monitoring of chlorobenzene(CBz) as an indicator for PCDD/Fs could be useful to control and optimize incinerator operating conditions.To test this strategy,CBz was analyzed together with PCDD/Fs in flue gas samples collected from a hospital waste incinerator.Moreover,lab experiments were conducted to investigate the eect of temperature and oxygen on CBz formation from fly ash from the same incinerator.The experimental results demonstrate that chlorobenzene(in particular PeCBz) correlate well with PCDD/Fs,in line with previous research.The optimum temperature of CBz formation is in a range of 350 to 400°C and CBz yield increases significantly with oxygen,in line with PCDD/Fs formation.This study is useful for confirming the de novo mechanism and defining correlations between CBz and PCDD/Fs. | Mi Yan,Xiaodong LiTong Chen,Shengyong Lu,Jianhua Yan,Kefa Cen State Key Laboratory of Clean Energy Utilization,Zhejiang University,Hangzhou 310027,China | 2010 | Journal of Environmental Sciences2010,22,10: | 16 |
| 8 | 基于改进LMD和能量相对熵的主动配电网故障定位方法显示文摘针对配电网发生单相接地故障且分布式电源(distributed generations,DGs)大量接入后,配电网结构和运行方式复杂多变、故障后电气量不明显、故障特征弱等特点,提出一种基于改进局部均值分解(improved local mean decomposition,ILMD)和能量相对熵的主动配电网故障定位方法。首先,利用镜像延拓将信号在两端延拓,消除LMD存在的端点效应,同时,在信号中加入自适应噪声,克服LMD存在的模态混叠问题,对各区段暂态零序电流进行ILMD分解;然后对分解后所有乘积函数(product function,PF)的能量相对熵进行计算,所有PF分量的相对能量熵之和即为区段间的相对能量熵,通过所设置的定位判据,对故障区段进行判断。仿真结果表明,所提算法在10 kV小电流接地系统和改进的IEEE33节点系统中,在不同的仿真条件下故障定位结果准确率高,验证了所提方法的准确性。 | 徐艳春 赵彩彩 孙思涵 MI Lu | 2021 | 中国电力2021,54,11: | 16 |
| 9 | Anatomy and influence of the splenic artery in laparoscopic spleen-preserving splenic lymphadenectomy显示文摘AIM: To investigate the splenic hilar vascular anatomy and the influence of splenic artery(Sp A) type in laparoscopic total gastrectomy with spleen-preserving splenic lymphadenectomy(LTGSPL).METHODS:The clinical anatomy data of 317 patients with upper- or middle-third gastric cancer who underwent LTGSPL in our hospital from January 2011 to December 2013 were collected. The patients were divided into two groups(concentrated group vs distributed group) according to the distance between the splenic artery's furcation and the splenic hilar region. Then, the anatomical layout, clinicopathologic characteristics, intraoperative variables, and postoperative variables were compared between the two groups.RESULTS: There were 205 patients with a concentrated type(64.7%) and 112 patients with a distributed type(35.3%) Sp A. There were 22 patients(6.9%) with a single branch of the splenic lobar vessels, 250(78.9%) with 2 branches, 43(13.6%) with 3 branches, and 2 patients(0.6%) with multiple branches. Eighty sevenpatients(27.4%) had type?Ⅰ?splenic artery trunk, 211(66.6%) had type Ⅱ, 13(4.1%) had type Ⅲ, and 6(1.9%) had type Ⅳ. The mean splenic hilar lymphadenectomy time(23.15 ± 8.02 vs 26.21 ± 8.84 min; P = 0.002), mean blood loss resulting from splenic hilar lymphadenectomy(14.78 ± 11.09 vs 17.37 ± 10.62 m L; P = 0.044), and number of vascular clamps used at the splenic hilum(9.64 ± 2.88 vs 10.40 ± 3.57; P = 0.040) were significantly lower in the concentrated group than in the distributed group. However, the mean total surgical time, mean total blood loss, and the mean number of harvested splenic hilar lymph nodes were similar in both groups(P > 0.05 for each comparison). There were also no significant differences in clinicopathological and postoperative characteristics between the groups(P > 0.05).CONCLUSION: It is of value for surgeons to know the splenic hilar vascular anatomy when performing LTGSPL. Patients with concentrated type Sp A may be optimal patients for training new surgeons. | Chao-Hui Zheng Mu Xu Chang-Ming Huang Ping Li Jian-Wei Xie Jia-Bin Wang Jian-Xian Lin Jun Lu Qi-Yue Chen Long-Long Cao Mi Lin | 2015 | World Journal of Gastroenterology2015,21,27: | 14 |

| 13 | Effects of recombinant retroviral vector mediated human insulin like growth factor-1 gene transfection on skeletal muscle growth in rat显示文摘Background This study transferred a recombinant gene encoding human insulin like growth factor-1 (hIGF-1) into modified primary skeletal myoblasts with a retroviral vector (pLgXSN ) and determined whether the hIGF-1 promoted growth of skeletal muscle in rat. Methods hIGF-1cDNA was amplified in vitro from normal human liver cells by using RT-PCR and cloned into plasmid vector pLgXSN. The recombinant vector pLghIGF-1SN and control vector pLgGFPSN were transfected into packaging cell PT67 and G418 was used to select positive colony. Myoblasts were infected with a high titre viral supernatant and transduction efficiency was evaluated as GFP expression. The expression of hIGF-1 mRNA in myoblasts was investigated by immunocytochemistry and RT-PCR. MTT assays detected the growth of myoblasts in vitro. Myoblasts transduced with pLghIGF-1SN were injected into hind limb muscles of 10-12 week male SD rats. Formed tissues were harvested 4 weeks later. Myocyte diameter, mean weight of hind limb and body were measured to evaluate the skeletal muscle growth. Results Recombinant retroviral plasmid vector pLghIGF-1SN was constructed successfully. The titre of the packaged recombinant retrovirus was 1×106 cfu/ml. The transfection rate of PT67 cells reached 100% after G418 screening. hIGF-1 expression was positive in myoblast-IGF-1. The proliferation rate of myoblast-IGF-1 in vitro was higher than GFP-myoblast or myoblast (P< 0.05). The mean weights of hind limb and body of rats injected myoblast-IGF-1 were higher than those of the rats injected with myoblast-GFP or myoblast (P< 0.05). Myocyte diameter had a significant increase in IGF-1 group compared to GFP group and myoblast group (P< 0.05). Conclusions The transfection of the human IGF-1 gene mediated by a retroviral vector can promote the growth of skeletal muscle in rats. Genetically modified primary skeletal myoblasts provide a possibly effective approach to treat some skeletal muscle diseases. | RONG Shu-Ling LU Yong-Xin LIAO Yu-Hua WANG Xiao-Lin GUO He-Ping CHANG Chao GAO Yan-Zhang MI Shao-Hua Wan Jian-Ping | 2006 | Chinese Medical Journal2006,,23: | 10 |

| 19 | Schistosoma japonicum egg antigen up-regulates fibrogenesis and inhibits proliferation in primary hepatic stellate cells in a concentration-dependent manner显示文摘AIM:To investigate the effects of different concentrations of Schistosoma japonicum(S.japonicum) egg antigen on fibrogenesis and apoptosis in primary hepatic stellate cells(HSCs).METHODS:A mouse model of schistosomiasis-associated liver fibrosis(SSLF) was established by infecting mice with schistosomal cercaria via the abdomen.HSCs were isolated from SSLF mice by discontinuous density gradient centrifugation,and their identity was confirmed by immunofluorescence double staining of α-smooth muscle actin(α-SMA) and desmin.The growth inhibitory effect and 50% inhibitory concentration(IC50) of S.japonicum egg antigen for primary HSCs(24 h) were determined using a cell counting kit-8(CCK-8) assay.The expression levels of α-SMA,matrix metalloproteinase-9(MMOL/LP-9) and tissue inhibitor of metalloproteinases-1(TIMP-1) in HSCs in response to different concentrations of S.japonicum egg antigen were detected by Western blotting and real-time reverse transcription-polymerase chain reaction.The levels of phospho-P38(P-P38),phospho-Jun N-terminal kinase(P-JNK) and phospho-Akt(P-AKT) in HSCs were detected by Western blotting.RESULTS:An SSLF mouse model was established,and primary HSCs were successfully isolated and cultured.S.japonicum egg antigen inhibited HSC proliferation in a concentration-dependent manner.The IC50 of the S.japonicum egg antigen was 244.53 ± 35.26 μg/mL.S.japonicum egg antigen enhanced α-SMA expression at both the mRNA and protein levels and enhanced TIMP-1 expression at the mRNA level in HSCs(P < 0.05),whereas the expression of MMOL/LP-9 was attenuated at both the mRNA and protein levels in a concentration-dependent manner(P < 0.05).A high concentration of S.japonicum egg antigen enhanced P-P38,P-JNK and P-AKT activation(P < 0.05).The changes in α-SMA and MMOL/LP-9 expression induced by S.japonicum egg antigen were closely correlated with P-P38 and P-JNK activation(P < 0.05).The attenuation of MMOL/LP-9 was also correlated with P-AKT activation(P < 0.05),but the increase in α-SMA expression was not.TIMP-1 expression was not correlated with P-P38,P-JNK or P-AKT activation.CONCLUSION:S.japonicum egg antigen promotes fibrogenesis,activates the P38/JNK mitogen-activated protein kinase and AKT/PI3K signaling pathways and inhibits proliferation in primary HSCs isolated from SSLF mice in a concentration-dependent manner. | Ping Liu Mi Wang Xiao-Dan Lu Shu-Juan Zhang Wang-Xian Tang | 2013 | World Journal of Gastroenterology2013,19,8: | 8 |
