| 2 | A life support-based comprehensive treatment regimen dramatically lowers the in-hospital mortality of patients with fulminant myocarditis: a multiple center study显示文摘Fulminant myocarditis(FM) has unacceptable high mortality. This study aimed to evaluate the therapeutic efficacy of a life support-based comprehensive treatment regimen(LSBCTR), a completely novel treatment regimen, for FM. A total of 169 FM patients recruited from January 2008 to December 2018 were divided into two groups: patients receiving LSBCTR(81 cases),which includes(i) mechanical life support(positive pressure respiration, intra-aortic balloon pump with or without extracorporeal membrane oxygenation),(ii) immunomodulation therapy using sufficient doses of glucocorticoids and immunoglobulins, and(iii) application of neuraminidase inhibitors, and those receiving conventional treatment(88 cases). The endpoints were in-hospital death and heart-transplantation. Of all the population, 44 patients(26.0%) died in hospitals. Inhospital mortality was 3.7%(3/81) for LSBCTR group and 46.6%(41/88) for traditional treatment(P<0.001). Early application of LSBCTR, mechanical life support, neuraminidase inhibitors, and immunomodulation therapy significantly contributed to reduction in in-hospital mortality. This study describes a novel treatment regimen for FM patients that dramatically reduces inhospital mortality. Its generalization and clinical application will efficiently save lives although further optimization is needed.This study offers an insight that virus infection induced inflammatory waterfall results in cardiac injury and cardiogenic shock and is the therapeutic target. | Sheng Li Shengyong Xu Chenze Li Xiao Ran Guanglin Cui Mengying He Kun Miao Chunxia Zhao Jiangtao Yan Rutai Hui Ning Zhou Yan Wang Jiangang Jiang Jing Zhang Daowen Wang | 2019 | Science China(Life Sciences)2019,62,3: | 43 |
| 3 | Effect of oxymatrine on the replication cycle of hepatitis B virus in vitro显示文摘AIM:To determine the antiviral mechanism or target of oxymatrine against hepatitis B virus(HBV).METHODS:HepG2.2.15 cells were incubated with culture medium containing 500 μg/mL of oxymatrine for 2 and 5 d.The surface antigen of HBV(HBsAg) and e antigen of HBV(HBeAg) in supernatant were determined by ELISA.HBV DNA in supernatant,and intracellular covalently closed circular DNA(cccDNA),relaxed circular DNA(rcDNA) and pregenomic RNA(pgRNA) were quantif ied by specif ic real-time polymerase chain reaction(PCR) or reverse transcription(RT)-PCR.RESULTS:Treatment with oxymatrine for 2 d and 5 d reduced the production of HBV by the cell line,as indicated by the decline of HBsAg(22.67%,t = 5.439,P = 0.0322 and 22.39%,t = 5.376,P = 0.0329,respectively),HBeAg(55.34%,t = 9.859,P = 0.0101 and 43.97%,t = 14.080,P = 0.0050) and HBV DNA(40.75%,t = 4.570,P = 0.0447 and 75.32%,t = 14.460,P = 0.0047) in the supernatant.Intracellular cccDNA was also markedly reduced by 63.98%(t = 6.152,P = 0.0254) and 80.83%(t = 10.270,P = 0.0093),and intracellular rcDNA by 34.35%(t = 4.776,P = 0.0413) and 39.24%(t = 10.050,P = 0.0097).In contrast,intracellular pgRNA increased by 6.90-fold(t = 8.941,P = 0.0123) and 3.18-fold(t = 7.432,P = 0.0176) after 500 μg/mL of oxymatrine treatment for 2 d and 5 d,respectively.CONCLUSION:Oxymatrine may inhibit the replication of HBV by interfering with the process of packaging pgRNA into the nucleocapsid,or inhibiting the activity of the viral DNA polymerase. | Xu, Wen-Sheng Zhao, Ke-Kai Miao, Xiao-Hui Ni, Wu Cai, Xiong Zhang, Rui-Qi Wang, Jun-Xue | 2010 | World Journal of Gastroenterology2010,16,16: | 27 |

| 5 | Nomogram to predict overall survival after gallbladder cancer resection in China显示文摘AIM To integrate clinically significant variables related to prognosis after curative resection for gallbladder carcinoma(GBC) into a predictive nomogram.METHODS One hundred and forty-two GBC patients who underwent curative intent surgical resection at Peking Union Medical College Hospital(PUMCH) were included. This retrospective case study was conducted at PUMCH of the Chinese Academy of Medical Sciences and Peking Union Medical College(CAMS & PUMC) in China from January 1, 2003 to January 1, 2018. The continuous variable carbohydrate antigen 19-9(CA19-9) was converted into a categorical variable(cCA19-9) based on the normal reference range. Stages 0 to IIIA were merged into one category, while the remaining stages were grouped into another category. Pathological grade X(GX) was treated as a missing value. A multivariate Cox proportional hazards model was used to select variables to construct a nomogram. Discrimination and calibration of the nomogram were performed via the concordance index(C-index) and calibration plots. The performance of the nomogram was estimated using the calibration curve. Receiver operating characteristic(ROC) curve analysis and decision curve analysis(DCA) were performed to evaluate the predictive accuracy and net benefit of the nomogram, respectively.RESULTS Of these 142 GBC patients, 55(38.7%) were male, and the median and mean age were 64 and 63.9 years, respectively. Forty-eight(33.8%) patients in this cohort were censored in the survival analysis. The median survival time was 20 months. A series of methods, including the likelihood ratio test and Akaike information criterion(AIC) as well as stepwise, forward, and backward analyses, were used to select the model, and all yielded identical results. Jaundice [hazard ratio(HR) = 2.9; 95% confidence interval(CI): 1.60-5.27], cCA19-9(HR = 3.2; 95%CI: 1.91-5.39), stage(HR = 1.89; 95%CI: 1.16-3.09), and resection(R)(HR = 2.82; 95%CI: 1.54-5.16) were selected as significant predictors and combined into a survival time predictive nomogram(C-index = 0.803; 95%CI: 0.766-0.839). High prediction accuracy(adjusted C-index = 0.797) was further verified via bootstrap validation. The calibration plot demonstrated good performance of the nomogram. ROC curve analysis revealed a high sensitivity and specificity. A high net benefit was proven by DCA.CONCLUSION A nomogram has been constructed to predict the overall survival of GBC patients who underwent radical surgery from a clinical database of GBC at PUMCH. | Yi Bai Zhi-Song Liu Jian-Ping Xiong Wei-Yu Xu Jian-Zhen Lin Jun-Yu Long Fei Miao Han-Chun Huang Xue-Shuai Wan Hai-Tao Zhao | 2018 | World Journal of Gastroenterology2018,24,45: | 25 |
| 6 | A putative 6-transmembrane nitrate transporter OsNRT1.1b plays a key role in rice under low nitrogen显示文摘OsNRT1.1a is a low-affinity nitrate(NO_3^-) transporter gene. In this study, another mRNA splicing product, OsNRT1.1b,putatively encoding a protein with six transmembrane domains, was identified based on the rice genomic database and bioinformatics analysis. OsNRT1.1a/OsNRT1.1b expression in Xenopus oocytes showed OsNRT1.1a-expressing oocytes accumulated ^(15)N levels to about half as compared to OsNRT1.1bexpressing oocytes. The electrophysiological recording of OsNRT1.1b-expressing oocytes treated with 0.25 mM NO_3^- confirmed ^(15)N accumulation data. More functional assays were performed to examine the function of OsNRT1.1b in rice. The expression of both OsNRT1.1a and OsNRT1.1b was abundant in roots and downregulated by nitrogen(N) deficiency. The shoot biomass of transgenic rice plants with OsNRT1.1a or OsNRT1.1b overexpression increased under various N supplies under hydroponic conditions compared to wild-type(WT). The OsNRT1.1a overexpression lines showed increased plant N accumulation compared to the WT in 1.25 mM NH_4NO_3 and 2.5 mM NO_3^- or NH_4^+ treatments, but not in 0.125 mM NH_4NO_3.However, OsNRT1.1b overexpression lines increased total N accumulation in all N treatments, including 0.125 m M NH_4NO_3,suggesting that under low N condition, OsNRT1.1b would accumulate more N in plants and improve rice growth, but also that OsNRT1.1a had no such function in rice plants. | Xiaorong Fan Huimin Feng Yawen Tan Yanling Xu Qisong Miao Guohua Xu | 2016 | Journal of Integrative Plant Biology2016,58,6: | 21 |
| 7 | Inhibition of 12-lipoxygenase reduces proliferation and induces apoptosis of hepatocellular carcinoma cells in vitro and in vivo显示文摘BACKGROUND:12-lipoxygenase(12-LOX) has been reported to be an important gene in cancer cell proliferation and survival,and tumor metastasis.However,its role in hepatocellular carcinoma(HCC) cells remains unknown.METHODS:Expression of 12-LOX was assessed in a diethylnitrosamine-induced rat HCC model,and in SMMC-7721,HepG2 and L-02 cells using immunohistochemical staining and reverse transcriptase-polymerase chain reaction(RT-PCR).GST-π and Ki-67 were determined in vivo by immunohistochemical staining.Apoptosis was evaluated by TUNEL assay.Cell viability and apoptosis were determined by MTT assay and flow cytometry,respectively.Apoptosis-related proteins in SMMC-7721 and HepG2 cells were detected by Western blotting.RESULTS:Immunohistochemical staining and RT-PCR showed that 12-LOX was over-expressed in rat HCC and two HCC cell lines,while the expression was inhibited by baicalein,a specific inhibitor of 12-LOX.Baicalein inhibited cell proliferation and induced apoptosis in rat HCC and both cell lines in a dose-and time-dependent manner.Our in vivo study demonstrated that baicalein also reduced neoplastic nodules.Mechanistically,baicalein reduced Bcl-2 protein expression coupled with a slight increase of the expression of Bax and activation of caspase-3.Furthermore,baicalein inhibited the activation of ERK-1/2(phosphorylated).Interestingly,the effects of baicalein were reversed by 12(S)-HETE,a metabolite of 12-LOX.CONCLUSIONS:Inhibition of 12-LOX leads to reduced numbers of HCC cells,partially caused by increased apoptosis.12-LOX may be a potential molecular target for HCC prevention and treatment. | Xi-Ming Xu,Guang-Jin Yuan,Jun-Jian Deng,Hong-Ting Guo,Miao Xiang,Fang Yang,Wei Ge and Shi-You Chen Cancer Center, Renmin Hospital of Wuhan University, Wuhan 430060, China Cancer Center, the 82nd Hospital of the Chinese PLA, Huai’an 223001, China Department of Physiology, Medical College of Wuhan University, Wuhan 430071, China Department of Physiology & Pharmacology, University of Georgia, Athens, GA 30602, USA | 2012 | Hepatobiliary & Pancreatic Diseases International2012,11,2: | 20 |

| 9 | Paclitaxel ameliorates fibrosis in hepatic stellate cells via inhibition of TGF-β/Smad activity显示文摘AIM: To investigated if paclitaxel can attenuate hepatic fi brosis in rat hepatic stellate cells (RHSCs). METHODS: RHSCs were cultured in vitro and randomly assigned to four groups: normal control group (treated only with Dulbecco's Modified Eagle's Medium), Taxol group (200 nmol/L paclitaxel was added to the cell culture), transforming growth factor (TGF)-β group (5 ng/mL recombinant human TGF-β1 was added to the cell culture), and TGF-β + Taxol group. TGF-β signaling cascade and status of various extracellular matrix proteins were evaluated by real time reverse transcriptase polymerase chain reaction and Western blotting. RESULTS: The paclitaxel treatment markedly suppressed Smad2/3 phosphorylation. This was associated with attenuated expression of collagen Ⅰ and Ⅲ and fi bronectin in RHSCs.CONCLUSION: These data indicate that 200 nmol/L paclitaxel ameliorates hepatic fi brosis via modulating TGF-β signaling, and that paclitaxel may have some therapeutic value in humans with hepatic fi brosis. | Jun Zhou, De-Wu Zhong, Qun-Wei Wang, Xiong-Ying Miao, Xun-Di Xu, Department of Hepatobiliary Surgery, Second Xiangya Hospital, Central South University, Changsha 410011, Hunan Province, China | 2010 | World Journal of Gastroenterology2010,16,26: | 17 |
| 10 | Astragalus extract inhibits destruction of gastric cancer cells to mesothelial cells by anti-apoptosis显示文摘AIM: To determine the inhibitory effect of Astragalus memebranaceushas on gastric cancer cell supernatantinduced apoptosis of human peritoneal mesothelial cells. METHODS: Human peritoneal mesothelial cell (HPMC) line HMrSV5 was co-incubated with gastric cancer cell supernatant (MKN45) and/or Astragalus memebranaceushas. Morphological changes in gastric cancer cells were observed under phase-contrast microscope. Quantitative cell damage was determined by MTT assay. Apoptosis was determined under transmission electron microscope and quantified by detecting acridine orange/ethidium bromide-stained (AO/EB) condensed nuclei under fluorescent microscope or by flow cytometry. Expressions of Bcl-2 and Bax were evaluated with immunostaining. RESULTS: Morphological changes and exfoliation occurred and naked areas appeared in cultured HMrSV5 cells 24 h after they were treated with gastric cancer cell supernatant. Cell supernatant from MKN45 gastric cancer cells induced apoptosis of HMrSV5 cells in a time-dependent manner. Obvious morphological changes were observed in cell apoptosis, such as condensation of chromatin, nuclear fragmentations and apoptotic bodies. Astragalus memebranaceus could partly suppress these changes and regulate the expressions of Bcl-2 and Bax in HMrSV5 cells.CONCLUSION: Gastric cancer cells induce apoptosis of HPMCs through the supernatant. Astragalus memebranaceushas inhibits this phenomenon and can be used an adjuvant chemothera-peutic agent in gastric cancer therapy. | Di Na Fu-Nan Liu Zhi-Feng Miao Zong-Min Du Hui-Mian Xu | 2009 | World Journal of Gastroenterology2009,15,5: | 17 |

| 14 | Combining CLUE-S and SWAT Models to Forecast Land Use Change and Non-point Source Pollution Impact at a Watershed Scale in Liaoning Province, China显示文摘Non-point source(NPS) pollution has become a major source of water pollution. A combination of models would provide the necessary direction and approaches designed to control NPS pollution through land use planning. In this study, NPS pollution load was simulated in urban planning, historic trends and ecological protection land use scenarios based on the Conversion of Land Use and its Effect at Small regional extent(CLUE-S) and Soil and Water Assessment Tool(SWAT) models applied to Hunhe-Taizi River Watershed, Liaoning Province, China. Total nitrogen(TN) and total phosphorus(TP) were chosen as NPS pollution indices. The results of models validation showed that CLUE-S and SWAT models were suitable in the study area. NPS pollution mainly came from dry farmland, paddy, rural and urban areas. The spatial distribution of TN and TP exhibited the same trend in 57 sub-catchments. The TN and TP had the highest NPS pollution load in the western and central plains, which concentrated the urban area and farm land. The NPS pollution load would increase in the urban planning and historic trends scenarios, and would be even higher in the urban planning scenario. However, the NPS pollution load decreased in the ecological protection scenario. The differences observed in the three scenarios indicated that land use had a degree of impact on NPS pollution, which showed that scientific and ecologically sound construction could effectively reduce the NPS pollution load in a watershed. This study provides a scientific method for conducting NPS pollution research at the watershed scale, a scientific basis for non-point source pollution control, and a reference for related policy making. | LIU Miao LI Chunlin HU Yuanman SUN Fengyun XU Yanyan CHEN Tan | 2014 | Chinese Geographical Science2014,24,5: | 15 |
| 15 | Aggravated ulcerative colitis caused by intestinal Metrnl deficiency is associated with reduced autophagy in epithelial cells显示文摘Metrnl is a newly identified secreted protein highly expressed in the intestinal epithelium.This study aimed to explore the role and mechanism of intestinal epithelial Metrnl in ulcerative colitis.Metrnl-/-(intestinal epithelial cell-specific Metrnl knockout)mice did not display any phenotypes of colitis under basal conditions.However,under administration of 3%dextran sodium sulfate(DSS)drinking water,colitis was more severe in Metrnl-/-mice than in WT mice,as indicated by comparisons of body weight loss,the presence of occult or gross blood per rectum,stool consistency,shrinkage in the colon,intestinal damage,and serum levels of inflammatory factors.DSS-induced colitis activated autophagy in the colon.This activation was partially inhibited by intestinal epithelial Metrnl deficiency,as indicated by a decrease in Beclin-1 and LC3-Ⅱ/Ⅰand an increase in p62 in DSS-treated Metrnl-/-mice compared with WT mice.These phenomena were further confirmed by observation of autophagosomes and immunofluorescence staining for LC3 in epithelial cells.The autophagy-related AMPK-mTOR-p70S6K pathway was also activated in DSS-induced colitis,and this pathway was partially blocked by intestinal epithelial Metrnl deficiency,as indicated by a decrease in AMPK phosphorylation and an increase in mTOR and p70S6K phosphorylation in DSS-treated Metrnl-/-mice compared with WT mice.Therefore,Metrnl deficiency deteriorated ulcerative colitis at least partially through inhibition of autophagy via the AMPK-mTOR-p70S6K pathway,suggesting that Metrnl is a therapeutic target for ulcerative colitis. | Sai-long Zhang Zhi-yong Li Dong-sheng Wang Tian-ying Xu Mao-bing Fan Ming-he Cheng Chao-yu Miao | 2020 | Acta Pharmacologica Sinica2020,41,6: | 14 |
| 16 | Staged carotid artery angioplasty and stenting for patients with high-grade carotid stenosis with high risk of developing hyperperfusion injury:a retrospective analysis of 44 cases显示文摘Background:Hyperperfusion syndrome(HPS)is a rare but potentially a life-threatening complication after carotid artery angioplasty and stenting(CAS).Staged CAS has been an alternative to prevent HPS.Materials and methods:44 of 908 patients with high-grade internal carotid artery stenosis or near occlusion were at risk of HPS because of poor collateral flow and impaired cerebral blood flow(CBF).They were treated with first(stage 1),followed by a full CAS(stage 2)1 month later.Their 30-day outcomes were tabulated and analysed.Results:During follow-up,1 of the 44(2.2%)patients developed HPS immediately,3(7%)had postprocedural HPS(ie,transcranial Doppler(TCD)>120%)without clinical symptoms and 3(7%)required stenting at stage 1 for carotid dissections.After stage 1,there were significant improvement between the preprocedural and postprocedural CBF(0.98±0.06 vs 0.85±0.05,p<0.05),mean transit time(MTT;1.05±0.05 vs 1.15±0.05,p<0.05),time to peak(TTP;1.04±0.06 vs 1.20±0.06,p<0.05)on CT perfusion(CTP),and CBF(66.41±7.41 vs 44.44±6.43,p<0.05)on TCD.After stage 2,improvement was seen in CBF(1.01±0.07 vs 0.98±0.06,p<0.05),MTT(1.01±0.05 vs 1.05±0.05,p<0.05),TTP(0.99±0.06 vs 1.04±0.06,p<0.05)on CTP and CBF(66.41±7.41 vs 93.78±18.81,p<0.05)on TCD.2 had postoperative increase of middle cerebral artery mean flow velocity of 120%after stage 2 without clinical symptoms.Conclusion:Staged carotid artery stenting probably decreased the chance of developing HPS in this group of selected patients.Although requiring a 2-step intervention,staged CAS may be a safe and effective alternative. | Dapeng Mo Gang Luo Bo Wang Ning Ma Feng Gao Xuan Sun Xiaotong Xu Zhongrong Miao | 2016 | Stroke & Vascular Neurology2016,1,4: | 14 |
| 17 | Neuroprotective effects of autophagy inhibition on hippocampal glutamate receptor subunits after hypoxia-ischemia-induced brain damage in newborn rats显示文摘Autophagy has been suggested to participate in the pathology of hypoxic-ischemic brain damage(HIBD).However,its regulatory role in HIBD remains unclear and was thus examined here using a rat model.To induce HIBD,the left common carotid artery was ligated in neonatal rats,and the rats were subjected to hypoxia for 2 hours.Some of these rats were intraperitoneally pretreated with the autophagy inhibitor 3-methyladenine(10 m M in 10 μL) or the autophagy stimulator rapamycin(1 g/kg) 1 hour before artery ligation.Our findings demonstrated that hypoxia-ischemia-induced hippocampal injury in neonatal rats was accompanied by increased expression levels of the autophagy-related proteins light chain 3 and Beclin-1 as well as of the AMPA receptor subunit GluR 1,but by reduced expression of GluR 2.Pretreatment with the autophagy inhibitor 3-methyladenine blocked hypoxia-ischemia-induced hippocampal injury,whereas pretreatment with the autophagy stimulator rapamycin significantly augmented hippocampal injury.Additionally,3-methyladenine pretreatment blocked the hypoxia-ischemia-induced upregulation of Glu R1 and downregulation of GluR2 in the hippocampus.By contrast,rapamycin further elevated hippocampal Glu R1 levels and exacerbated decreased GluR2 expression levels in neonates with HIBD.Our results indicate that autophagy inhibition favors the prevention of HIBD in neonatal rats,at least in part,through normalizing Glu R1 and GluR2 expression. | Li-xiao Xu Xiao-juan Tang Yuan-yuan Yang Mei Li Mei-fang Jin Po Miao Xin Ding Ying Wang Yan-hong Li Bin Sun Xing Feng | 2017 | Neural Regeneration Research2017,12,3: | 12 |
| 18 | Nicotinamide phosphoribosyltransferase aggravates inflammation and promotes atherosclerosis in ApoE knockout mice显示文摘Nicotinamide phosphoribosyltransferase (Nampt) is the rate-limiting enzyme of nicotinamide adenine dinucleotide (NAD) salvage biosynthesis in mammals, and is involved in fundamental physiological processes and pathophysiology of many diseases. Thus far, however, the role of Nampt in atherosclerosis development is still in debate. In this study, we crossed global Nampt transgenic mice (Nampt-Tg) with a well-established atherosclerosis animal model (ApoE knockout mice, ApoE-/-) to generate ApoE-/-;Nampt-Tg mice and investigated the effects of Nampt overexpression on atherosclerosis development in ApoE-/- mice. Both ApoE-/- and ApoE-/-;Nampt-Tg mice were fed with a pro-atherosclerotic high-fat diet (HFD) for 16 weeks. Their serum lipid contents and atherosclerotic lesion were assessed. The results showed that there was no significant difference in body weight or serum levels of glucose, total cholesterol, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol between the two strains of mice, but ApoE-/-;Nampt-Tg mice had a significantly higher level of serum non-esterified fatty acid. Compared with ApoE-/- mice, ApoE-/-;Nampt-Tg mice displayed significantly increased atherosclerotic lesion area and thickness, lower collagen content, decreased collagen I/III ratio (collagen immaturation), increased number of apoptotic cells, and enhanced activities of caspase-3, caspase-8, and caspase-9. Moreover, macrophage infiltration (F4/80 staining), tumor necrosis factor signaling, and chemokines expression (ICAM-1 and CXCR-4) were all activated in aortic atherosclerotic plaque of ApoE-/-;Nampt-Tg mice compared with ApoE-/- mice. Our results provide in vivo evidence that Nampt transgene aggravates atherosclerotic inflammation and promotes atherosclerosis development in ApoE-/- mice. | Yuan-yuan Kong Guo-qiang Li Wen-jie Zhang Xia Hua Can-can Zhou Tian-ying Xu Zhi-yong Li Pei Wang Chao-yu Miao | 2019 | Acta Pharmacologica Sinica2019,40,9: | 12 |
| 19 | Effects of intermittent negative pressure on osteogenesis in human bone marrow-derived stroma cells显示文摘Objective:We investigated the effects of intermittent negative pressure on osteogenesis in human bone marrowderived stroma cells(BMSCs) in vitro. Methods:BMSCs were isolated from adult marrow donated by a hip osteoarthritis patient with prosthetic replacement and cultured in vitro. The third passage cells were divided into negative pressure treatment group and control group. The treatment group was induced by negative pressure intermittently(pressure:50 kPa,30 min/times,and twice daily). The control was cultured in conventional condition. The osteogenesis of BMSCs was examined by phase-contrast microscopy,the determination of alkaline phosphatase(ALP) activities,and the immunohistochemistry of collagen type I. The mRNA expressions of osteoprotegerin(OPG) and osteoprotegerin ligand(OPGL) in BMSCs were analyzed by real-time polymerase chain reaction(PCR). Results:BMSCs showed a typical appearance of osteoblast after 2 weeks of induction by intermittent negative pressure,the activity of ALP increased significantly,and the expression of collagen type I was positive. In the treatment group,the mRNA expression of OPG increased significantly(P<0.05) and the mRNA expression of OPGL decreased significantly(P<0.05) after 2 weeks,compared with the control. Conclusion:Intermittent negative pressure could promote osteogenesis in human BMSCs in vitro. | Zhi YANG Miao LIU Yin-gang ZHANG Xiong GUO Peng XU | 2009 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2009,10,3: | 12 |
