2Transplantation of collagen scaffold with autologous bone marrow mononuclear cells promotes functional endometrium reconstruction via downregulating ΔNp63 expression in Asherman's syndrome显示文摘Asherman's syndrome(AS) is a common disease that presents endometrial regeneration disorder. However, little is known about its molecular features of this aregenerative endometrium in AS and how to reconstruct the functioning endometrium for the patients with AS. Here, we report that ΔNp63 is significantly upregulated in residual epithelial cells of the impaired endometrium in AS; the upregulated-ΔNp63 induces endometrial quiescence and alteration of stemness. Importantly, we demonstrate that engrafting high density of autologous bone marrow mononuclear cells(BMNCs) loaded in collagen scaffold onto the uterine lining of patients with AS downregulates ΔNp63 expression, reverses ΔNp63-induced pathological changes, normalizes the stemness alterations and restores endometrial regeneration. Finally, five patients achieved successful pregnancies and live births. Therefore, we conclude that ΔNp63 is a crucial therapeutic target for AS. This novel treatment significantly improves the outcome for the patients with severe AS.Guangfeng Zhao Yun Cao Xianghong Zhu Xiaoqiu Tang Lijun Ding Haixiang Sun Juan Li Xinan Li Chenyan Dai Tong Ru Hui Zhu Jingjie Lu Caimei Lin Jingmei Wang Guijun Yan Huiyan Wang Lei Wang Yimin Dai Bin Wang Ruotian Li Jianwu Dai Yan Zhou Yali Hu 2017Science China(Life Sciences)2017,60,4:39
3Neuroprotective effect of bispectral index-guided fast-track anesthesia using sevoflurane combined with dexmedetomidine for intracranial aneurysm embolization显示文摘Dexmedetomidine has sedative, anxiolytic, analgesic, anti-sympathetic, and anti-shivering effects. Dexmedetomidine might be effective in combination with sevoflurane for anesthesia, but prospective randomized controlled clinical trials with which to verify this hypothesis are lacking. In total, 120 patients who underwent embolization of an intracranial aneurysm were recruited from Anhui Provincial Hospital and Renmin Hospital of Wuhan University of China and randomly allocated to two groups. After intraoperative administration of 2% to 3% sevoflurane inhalation, one group of patients received pump-controlled intravenous injection of 1.0 μg/kg dexmedetomidine for 15 minutes followed by maintenance with 0.3 μg/kg/h until the end of surgery; the other group of patients only underwent pump-controlled infusion of saline. Bispectral index monitoring revealed that dexmedetomidine-assisted anesthesia can shorten the recovery time of spontaneous breathing, time to eye opening, and time to laryngeal mask removal. Before anesthetic induction and immediately after laryngeal mask airway removal, the glucose and lactate levels were low, the S100β and neuron-specific enolase levels were low, the perioperative blood pressure and heart rate were stable, and postoperative delirium was minimal. These findings indicate that dexmedetomidine can effectively assist sevoflurane for anesthesia during surgical embolization of intracranial aneurysms, shorten the time to consciousness and extubation, reduce the stress response and energy metabolism, stabilize hemodynamic parameters, and reduce adverse reactions, thereby reducing the damage to the central nervous system.Chao-liang Tang Juan Li Zhe-tao Zhang Bo Zhao Shu-dong Wang Hua-ming Zhang Si Shi Yang Zhang Zhong-yuan Xia 2018Neural Regeneration Research2018,13,2:32

5Pharmacokinetics and pharmacodynamics of Da-Cheng-Qi decoction in the liver of rats with severe acute pancreatitis显示文摘AIM To explore the pharmacokinetics and pharmacodynamics of Da-Cheng-Qi decoction(DCQD) in the liver of rats with severe acute pancreatitis(SAP) based on an herbal recipe tissue pharmacology hypothesis.METHODS Healthy male Sprague-Dawley rats were randomly divided into a sham operation group(SOG); a model group(MG); and low-, median- and high-dose treatment groups(LDG, MDG, and HDG, respectively). Different dosages(6, 12 and 24 g/kg for the LDG, MDG, and HDG, respectively) of DCQD were administered to the rats with SAP. The tissue concentrations of aloeemodin, rhein, emodin, chrysophanol, honokiol, rheo chrysophanol, magnolol, hesperidin, naringenin and naringin in the liver of the treated rats were detected by high-performance liquid chromatography tandem mass spectrometry. Alanine transaminase(ALT) and aspartate transaminase(AST) in serum, inflammatory mediators in the liver and pathological scores were evaluated.RESULTS The major components of DCQD were detected in the liver, and their concentrations increased dosedependently. The high dose of DCQD showed a maximal effect in ameliorating the pathological damages, decreasing the pro-inflammatory mediators tumor necrosis factor-α and interleukin(IL)-6 and increasing anti-inflammatory mediators IL-4 and IL-10 in the liver. The pathological scores in the pancreas for the MG were significantly higher than those for the SOG(P < 0.05). DCQD could reduce the pathological scores in the pancreas and liver of the rats with SAP, especially in the HDG. Compared to the SOG, the ALT and AST levels in serum were higher in the MG(P < 0.05), while there was no statistical difference in the MG and HDG.CONCLUSION DCQD could alleviate liver damage by altering the inflammatory response in rats with SAP based on the liver distribution of its components.Yu-Mei Zhang Hong-Yu Ren Xian-Lin Zhao Juan Li Jun-Yi Li Fu-Sheng Wu Hang Su Wen-Fu Tang 2017World Journal of Gastroenterology2017,23,8:26
6Dynamic Prediction Method of Production Logistics Bottleneck Based on Bottleneck Index显示文摘In modern manufacturing pattern,there are many uncertain factors in the modern manufacturing process,such as changes of product attribute,changes of manufacturing resources' state,and so on,which cause production logistics bottleneck frequently shift,and make decisions of production planning and control based on formed bottleneck deviated from practical production process.Considering these factors,present researches mainly apply afterwards control to optimize production process to passively adapt to bottleneck changes.If the direction of bottleneck shifting can be accurately forecasted,the transition from afterwards control of chasing bottleneck to beforehand control can be realized.Therefore,aiming at the phenomenon of production logistics bottleneck shifting under uncertain manufacturing circumstances,this paper starts off with dynamic property of capability and requirement and then builds the concepts of bottleneck degree and bottleneck index to describe dynamic bottleneck characteristic of production unit;taken production capability,production load and quality assurance capability into consideration,mathematical model of bottleneck index is established to measure bottleneck degree accurately,consequently,quantitative research on mechanism of production logistics shifting is achieved.Based on bottleneck index,the prediction model of production logistics bottleneck is founded to predict dynamic change of bottleneck accurately.Finally,an example of forecasting and monitoring the production logistics bottleneck in one manufacturing shop is given to testify the validation and practicability of the prediction method.LIU Mingzhou TANG Juan GE Maogen JIANG Zengqiang HU Jing LING Lin 2009Chinese Journal of Mechanical Engineering2009,22,5:22

8Intercropping with Solanum nigrum and Solanum photeinocarpum from Two Ecoclimatic Regions Promotes Growth and Reduces Cadmium Uptake of Eggplant Seedlings显示文摘Soil contamination by heavy metals is a serious environmental problem worldwide, and reduction of heavy metal accumulation in vegetables grown on contaminated land is a matter of urgency. A pot experiment was conducted to study the effects of intercropping with the Cd hyperaccumulators Solanum nigrum and Solanum photeinocarpum from two ecoclimatic regions, Ya'an and Chengdu,Sichuan Province, China, on the growth and cadmium(Cd) uptake of eggplant(Solanum melongena L.). The biomass, photosynthetic pigment contents, and activities of antioxidant enzymes of eggplant were enhanced by intercropping. The biomass of eggplant was the highest after intercropping with S. photeinocarpum from Ya'an, but did not differ significantly from that after intercropping with S. nigrum from Chengdu. The shoot Cd content of eggplant was significantly reduced by intercropping with the hyperaccumulators,which ranked as follows: S. nigrum from Chengdu > S. nigrum from Ya'an > S. photeinocarpum from Chengdu > S. photeinocarpum from Ya'an, with the decreases being 19.60%, 14.36%, 9.66%, and 6.42%, respectively, as compared with the control. The lowest shoot Cd content and translocation factor of eggplant were attained after intercropping with S. nigrum from Chengdu. Therefore, it was feasible to intercrop eggplant with S. nigrum and S. photeinocarpum on Cd-contaminated soil.TANG Yi HE Juan YU Xuena XIE Yongdong LIN Lijin SUN Guochao LI Huanxiu LIAO Mingan LIANG Dong XIA Hui WANG Xun ZHANG Jing LIU Zejing TU Lihua LIU Li 2017Pedosphere2017,27,3:17

11Omentin-1 prevents inflammation-induced osteoporosis by downregulating the pro-inflammatory cytokines显示文摘Osteoporosis is a frequent complication of chronic inflammatory diseases and increases in the pro-inflammatory cytokines make an important contribution to bone loss by promoting bone resorption and impairing bone formation. Omentin-1 is a newly identified adipocytokine that has anti-inflammatory effects, but little is known about the role of omentin-1 in inflammatory osteoporosis. Here we generated global omentin-1 knockout(omentin-1^(-/-)) mice and demonstrated that depletion of omentin-1 induces inflammatory bone loss-like phenotypes in mice, as defined by abnormally elevated pro-inflammatory cytokines, increased osteoclast formation and bone tissue destruction, as well as impaired osteogenic activities. Using an inflammatory cell model induced by tumor necrosis factor-α(TNF-α), we determined that recombinant omentin-1 reduces the production of proinflammatory factors in the TNF-α-activated macrophages, and suppresses their anti-osteoblastic and pro-osteoclastic abilities. In the magnesium silicate-induced inflammatory osteoporosis mouse model, the systemic administration of adenoviral-delivered omentin-1 significantly protects from osteoporotic bone loss and inflammation. Our study suggests that omentin-1 can be used as a promising therapeutic agent for the prevention or treatment of inflammatory bone diseases by downregulating the proinflammatory cytokines.Shan-Shan Rao Yin Hu Ping-Li Xie Jia Cao Zhen-Xing Wang Jiang-Hua Liu Hao Yin Jie Huang Yi-Juan Tan Juan Luo Ming-Jie Luo Si-Yuan Tang Tuan-Hui Chen Ling-Qing Yuan Er-Yuan Liao Ran Xu Zheng-Zhao Liu Chun-Yuan Chen Hui Xie 2018Bone Research2018,6,2:16

13Heterotopic pancreas in the gastrointestinal tract显示文摘Heterotopic pancreas is defined as pancreatic tissue found outside the usual anatomical location of the pancreas. It is often an incidental finding and can be found at different sites in the gastrointestinal tract. It may become clinically evident when complicated by pathological changes such as inflammation, bleeding, obstruction, and malignant transformation. In this report, a 60-year-old man with carcinoid syndrome caused by heterotopic pancreatic tissue in the duodenum is described, along with a 62-year-old man with abdominal pain caused by heterotopic pancreatic tissue in the gastric antrum. The difficulty of making an accurate diagnosis is highlighted. The patients remain healthy and symptom-free after follow-up of 1 year. Frozen sections may help in deciding the extent of resection intraoperatively. Although heterotopic pancreas is rare, it should be considered in the differential diagnosis of gastrointestinal stromal tumor.Zhou Yuan Jie Chen Qi Zheng Xin-Yu Huang Zhe Yang Juan Tang 2009World Journal of Gastroenterology2009,15,29:15
14Liver Enzymes Concentrations Are Closely Related to Pre-diabetes:Findings of the Shanghai Diabetes Study Ⅱ (SHDS Ⅱ)显示文摘Objective To investigate the relationship of liver enzymes with hyperglycemia in a large population in Shanghai and identify the association between liver enzymes and insulin resistance.Methods A total of 3 756 participants were enrolled.Each participant underwent an oral glucose tolerance test and completed a questionnaire.Anthropometric indices were recorded and serum samples were collected for measurement.Results Liver enzymes concentrations were independently associated with i-IGT,IFG+IGT,and diabetes.With the increase of ALT and GGT concentrations,ORs for i-IGT,IFG+IGT,and diabetes increased gradually.By comparing patients in the highest quartile of GGT concentrations or ALT concentrations with those in the lowest quartile (Q1),ORs for i-IGT,IFG+IGT,or diabetes was significant after adjustment.Both ALT and GGT concentrations were linearly correlated with HOMA-IR and independently associated with HOMA-IR [ALT OR (95% CI):2.56 (1.51-4.34) P=0.00;GGT OR (95% CI):2.66 (1.53-4.65) P=0.00].Conclusion Serum ALT and GGT concentrations were closely related to pre-diabetes and diabetes in the Shanghai population and positively associated with insulin resistance.GAO Fei PAN Jie Min HOU Xu Hong FANG Qi Chen LU Hui Juan TANG Jun Ling GU Hui Lin PAN Zhi Jian YAO You Hua SHEN Wei Zhen JIA Wei Ping 2012Biomedical and Environmental Sciences2012,25,1:15
15miR-374b-5p suppresses RECK expression and promotes gastric cancer cell invasion and metastasis显示文摘AIM:To profile expression of micro RNAs(mi RNAs)in gastric cancer cells and investigate the effect of mi R-374b-5p on gastric cancer cell invasion and metastasis.METHODS:An mi RNA microarray assay was performed to identify mi RNAs differentially expressed in gastric cancer cell lines(MGC-803 and SGC-7901)compared with a normal gastric epithelial cell line.Upregulation of mi R-374b-5p was newly identified and confirmed via quantitative real-time reverse transcriptionPCR(q RT-PCR).MGC-803 cells were transfected with a synthesized anti-mi R-374b-5p sequence or a control vector using Lipofectamine reagent,or treated with transfection reagent alone or phosphate-buffered saline as controls.Rate of transfection was verified after 48 h by q RT-PCR.Cells were then subjected to transwell migration,wound scratch and cell counting kit-8 assays.A bioinformatic analysis to identify mi R-374b-5p target genes was performed using mi Randa,Pic Tar and Target Scan software.A dual luciferase reporter assay was performed to evaluate the influence of mi R-374b-5p on target gene activation,and q RT-PCR and Western blot were used to evaluate the levels of target m RNA and protein following transfection with mi R-374b-5p antisense oligonucleotides.RESULTS:The microarray profiling revealed downregulation of 14(fold change<0.667;P<0.05)and upregulation of 12(fold change>1.50;P<0.05)mi RNAs in MGC-803 and SGC-7901 cells compared with GES-1 controls.The upregulation of mi R-374b-5p(fold change=1.75 and 1.64 in MGC-803 and SGC-7901,respectively;P<0.05)was confirmed by q RT-PCR.Compared with the control groups,the restoration of mi R-374b-5p expression with anti-mi R-374b-5p significantly suppressed the metastasis,invasion and proliferation of MGC-803 cells.The bioinformatic analysis predicted that the 3’untranslated region(UTR)of reversion-inducing cysteine-rich protein with Kazal motif(RECK)contains three mi R-374b-5p target sequences.RECK was verified as a target gene in a dual luciferase reporter assay showing that activation of RECK 3’UTR-pmir GLO was increased by co-transfection with mi R-374b-5p.Finally,transfection of mi R-374b-5p antisense oligonucleotides increased m RNA and protein levels of RECK in MGC-803cells(P<0.05).CONCLUSION:These findings indicate that upregulation of mi R-374b-5p contributes to gastric cancer cell metastasis and invasion through inhibition of RECK expression.Juan Xie Zhi-Hui Tan Xia Tang Ming-Shu Mo Yan-Ping Liu Run-Liang Gan Yi Li Li Zhang Guo-Qing Li 2014World Journal of Gastroenterology2014,20,46:15
16Arabidopsis F-box gene FOA1 involved in ABA signaling显示文摘The expression of FOA1(F-box overexpressed/oppressed ABA signaling) in different organs of Arabidopsis,and in response to ABA and NaCl,was analyzed.The expression level of FOA1 is higher in the root and is lower in the stem,and is induced rapidly by ABA and NaCl.The phenotypes of T-DNA insertion mutant foa1 and FOA1 overexpression lines FOA1ox1 and FOA1ox2 were analyzed.The foa1 mutant exhibited a lower germination rate,shorter root length,more stomatal opening,increased proline accumulation and hypersensitivity to ABA compared with the wild type.In contrast,the overexpression lines showed lower sensitivity to ABA than the wild type.The expression levels of several ABA and stress-responsive transcription factors and genes were altered in the foa1 mutant in response to ABA.Compared with the wild type,the expression levels of ABA-responsive transcription factors were higher,but ABA and stress-responsive genes were lower in foa1 mutant.This study demonstrates that FOA1 is an ABA signaling-related gene,and may play a negative role in ABA signaling.PENG Juan YU DaShi WANG LiQun XIE MinMin YUAN CongYing WANG Yu TANG DongYing ZHAO XiaoYing LIU XuanMing 2012Science China(Life Sciences)2012,55,6:12
17m^6A-dependent biogenesis of circular RNAs in male germ cells显示文摘The majority of circular RNAs(circRNAs)spliced from coding genes contain open reading frames(ORFs)and thus,have protein coding potential.However,it remains unknown what regulates the biogenesis of these ORF-containing circRNAs,whether they are actually translated into proteins and what functions they play in specific physiological contexts.Here,we report that a large number of circRNAs are synthesized with increasing abundance when late pachytene spermatocytes develop into round and then elongating spermatids during murine spermatogenesis.For a subset of circRNAs,the back splicing appears to occur mostly at m^6A-enriched sites,which are usually located around the start and stop codons in linear mRNAs.Consequently,approximately a half of these male germ cell circRNAs contain large ORFs with m^6A-modified start codons in their junctions,features that have been recently shown to be associated with protein-coding potential.Hundreds of peptides encoded by the junction sequences of these circRNAs were detected using liquid chromatography coupled with mass spectrometry,suggesting that these circRNAs can indeed be translated into proteins in both developing(spermatocytes and spermatids)and mature(spermatozoa)male germ cells.The present study discovered not only a novel role of m^6A in the biogenesis of coding circRNAs,but also a potential mechanism to ensure stable and long-lasting protein production in the absence of linear mRNAs,i.e.,through production of circRNAs containing large ORFs and m^6A-modified start codons in junction sequences.Chong Tang Yeming Xie Tian Yu Na Liu Zhuqing Wang Rebekah J.Woolsey Yunge Tang Xinzong Zhang Weibing Qin Ying Zhang Ge Song Weiwei Zheng Juan Wang Weitian Chen Xiongyi Wei Zhe Xie Rachel Klukovich Huili Zheng David R.Quilici Wei Yan 2020Cell Research2020,30,3:12

20Pharmacokinetics and pharmacodynamics of Shengjiang decoction in rats with acute pancreatitis for protecting against multiple organ injury显示文摘AIM To explore the pharmacokinetics and pharmacodynamics of Shengjiang decoction(SJD) in rats with acute pancreatitis(AP) for protecting against multiple organ injury.METHODS An AP model was established by retrograde perfusion of 3.5% sodium taurocholate into the biliopancreatic duct, and a control group(CG) received 0.9% sodium chloride instead. Twelve male Sprague-Dawley rats were randomly divided into a CG treated with SJD(CG + SJD) and a model group treated with SJD(MG + SJD), both of which were orally administered with SJD(5 g/kg) 2 h after surgery. Blood samples were collected via the tail vein at 10, 20, and 40 min and 1, 2, 3, 4, 6, 8, and 12 h after a single dose of SJD to detect its main components using high-performance liquid chromatography-tandem mass spectrometry. The pharmacokinetic parameters were compared. In the pharmacodynamic experiment, 18 male SpragueDawley rats were randomly divided into a CG, an AP model group(MG), and an SJD treated AP group(SJDG). Serum amylase, lipase, and inflammatory cytokines were measured, and heart, lung, liver, spleen, pancreas, kidney, and intestine tissues were collected for pathological examination.RESULTS The MG + SJD displayed significantly shorter mean residence time(MRT) and higher clearance(CL) for emodin and aloe-emodin; significantly shorter time of maximum concentration and T1/2 and a lower area under curve(AUC) for aloe-emodin; a significantly higher AUC and lower CL for rhein; and longer MRT and lower CL for chrysophanol than the CG + SJD. In the pharmacodynamic experiment, the amylase, interleukin(IL)-6, IL-10, and tumor necrosis factor(TNF)-α levels in the MG were higher than those in the CG(P < 0.05). After the herbal decoction treatment, the SJDG had higher IL-10 and lower TNF-α levels than the MG(P < 0.05). The MG had the highest pathological scores, and the pathological scores of the lung, pancreas, kidney, and intestine in the SJDG were significantly lower than those in the MG(P < 0.05).CONCLUSION AP may have varying effects on the pharmacokinetics of the major SJD components in rats. SJD might alleviate pathological injuries of the lung, pancreas, kidney, and intestine in rats with AP via regulating pro-and antiinflammatory responses, which might guide the clinical application of SJD for AP treatment.Lv Zhu Jun-Yi Li Yu-Mei Zhang Hong-Xin Kang Huan Chen Hang Su Juan Li Wen-Fu Tang 2017World Journal of Gastroenterology2017,23,46:10
