| 2 | miR-188-5p regulates proliferation and invasion via PI3K/Akt/MMP-2/9 signaling in keloids显示文摘Keloids(KDs)and hypertrophic scars(HSs),two forms of pathological scars,seriously affect the physical and psychological health of patients.Despite many similarities with HSs,KDs are characterized by invasion and a high rate of recurrence after surgery,features they share in common with tumors.The underlying molecular mechanisms of this phenomenon have not been fully elucidated.In this study,we used microRNA(miRNA)array analysis to search for invasion-associated miRNAs in KDs.The expression of miR-188-5p in KDs,HSs,normal skin(NS)tissues,and cell lines was measured by quantitative real-time polymerase chain reaction.Furthermore,cell proliferation,migration,and invasion were detected in KD fibroblasts(KFs)and HS fibroblasts(HSFs),and interrelated proteins were ascertained by western blot analysis.It was found that miR-188-5p was significantly decreased in KD tissue compared with HS and NS tissues.Upregulated expression of miR-188-5p suppressed KF proliferation,migration,and invasion;and decreased expression of miR-188-5p also promoted HSF proliferation,migration,and invasion.The protein levels of MMP-2,MMP-9,PI3K,and p-Akt in miR-188-5p mimic-transfected KFs were repressed.In contrast,after transfection with miR-188-5p inhibitor,the protein levels of MMP-2,MMP-9,PI3K,and p-Akt were higher than the control in HSFs.Treatment with PI3K/Akt inhibitor LY294002 in KFs with miR-188-5p inhibitor did not further reduce their proliferation,migration,and invasion.The upregulation of MMP-2 and MMP-9 by miR-188-5p inhibitor could be abolished by LY294002.These findings together demonstrate a tumor-suppressive role of miR-188-5p in KD proliferation and invasion via PI3K/Akt/MMP-2/9 signaling,indicating that miR-188-5p may be a potential prognostic marker and therapeutic target for KDs. | Wenyan Zhu Xiaoyan Wu Bo Yang Xiaodong Yao Xiaomei Cui Pan Xu Xiaodong Chen | 2019 | Acta Biochimica et Biophysica Sinica2019，51，2： | 9 |
| 3 | Fractional Fourier domain hopped communication method based on chirp modulation for underwater acoustic channels显示文摘To improve the data rate of underwater acoustic frequency-hopped communications, frequency hopping is applied to different orders of fractional Fourier domain(Fr FD), to enable non-intrusive, bandwidth-limited acoustic communications.An Fr FD frequency-hopped communication method based on chirp modulation, namely multiple chirp shift keying-Fr FD hopping(MCSK-Fr FDH), is proposed for underwater acoustic channels. Validated by both simulations and experimental results, this method can reach a bandwidth efficiency twice more than conventional frequency-hopped methods with the same data rate and anti-multipath capability, suggesting that the proposed method achieves a better performance than the traditional frequencyhopped communication in underwater acoustic communication channels. Results also show that in practical scenarios, the MCSKFr FDH system with longer symbol length performs better at the low signal-to-noise ratio(SNR), while the system with larger frequency sweeping range performs better at a high SNR. | Xingbin Tu Xiaomei Xu Zheguang Zou Liangliang Yang Jianming Wu | 2017 | Journal of Systems Engineering and Electronics2017，28，3： | 9 |
| 4 | Mild moxibustion at Tianshu (ST 25) decreases expression of prokineticin-1 and prokineticin receptor-1 in colon tissue of rats with chronic visceral hyperalgesia显示文摘Prokineticin-1 and prokineticin receptor-1 play important roles in visceral hypersensitivity and in-flammatory pain. Visceral hypersensitivity is closely associated with irritable bowel syndrome. Mild moxibustion can relieve chronic visceral hyperalgesia in rats with irritable bowel syndrome. We hypothesized that prokineticin-1 and prokineticin receptor-1 is the key target in the mechanism. This study established chronic visceral hyperalgesia rat models by colorectal distention. Protein and mRNA expression of prokineticin-1 and prokineticin receptor-1 were determined by immunohisto-chemical method and fluorescence quantitative-PCR, respectively, and were found to be signifi-cantly increased in visceral hyperalgesic rats. Mild moxibustion at Tianshu (ST 25) decreased prokineticin-1 and prokineticin receptor-1 expression in chronic visceral hyperalgesia rats and lessen the chronic visceral hyperalgesia in rats with irritable bowel syndrome at different levels of colorectal distention pressure. | Luyi Wu Chunhui Bao Linbao Ge Cili Zhou Huirong Liu Li Qi Tao Yi Huangan Wu Xiaomei Wang | 2011 | Neural Regeneration Research2011，6，33： | 9 |
| 5 | Analgesic action of suspended moxibustion in rats with chronic visceral hyperalgesia correlates with enkephalins in the spinal cord显示文摘Rats that modeled chronic visceral hyperalgesia received suspended moxibustion at bilateral Tianshu (ST25) and Shangjuxu (ST37) once daily over a period of 7 days. Results show that suspended moxibustion significantly depressed abdominal withdrawal reflex scores and increased enkephalin concentration in the spinal cord. The experimental findings suggest that spinal enkephalins contributed to the analgesic effect of suspended moxibustion in rats with chronic visceral hyperalgesia. | Tao Yi Li Qi Huangan Wu Xiaopeng Ma Huirong Liu Xiaomei Wang | 2012 | Neural Regeneration Research2012，7，3： | 9 |
| 6 | Electroacupuncture at Tianshu (ST 25) for diarrhea-predominant irritable bowel syndrome using positron emission tomography Changes in visceral sensation center显示文摘Previous studies have demonstrated that electroacupuncture therapy is effective in the treatment of irritable bowel syndrome. However, the precise mechanism of this therapy is unknown. The present study served to investigate the effects of electroacupuncture therapy on treatment of patients with diarrhea-predominant irritable bowel syndrome (IBS). We compared brain activation maps based on the changes of cerebral glucose metabolism obtained by 18-fluorodeoxyglucose positron emission tomography scanning under three conditions: resting, rectal balloon distension and rectal balloon distension plus electroacupuncture. Under the resting condition, compared with healthy controls, IBS patients displayed an increasing regional cerebral metabolic rate of glucose over a wide range: bilateral superior temporal gyrus, right middle occipital gyrus, superior frontal gyrus and bilateral middle frontal gyrus. However, there was no significant activity in the visceral pain center. Compared with the resting condition, under the rectal balloon distension condition, patients with IBS had a greater regional cerebral metabolic rate of glucose in the prefrontal cortex, left anterior cingulate cortex, postcentral gyrus, precentral gyrus and temporal gyrus. Under the rectal balloon distension plus electroacupuncture condition, stimulation by electroacupuncture at Tianshu (ST 25) manifested a decreased regional cerebral metabolic rate of glucose in the left cingulate gyrus, right insula, right caudate nucleus, fusiform gyrus and hippocampal gyrus. Electroacupuncture therapy relieved abdominal pain, distension or discomfort by decreasing glucose metabolism in the brain. | Huirong Liu Li Qi Xiaolong Wang Yihui Guan Chuantao Zuo Linying Tan Lingsong Yuan Xiaopeng Ma Xiaomei Wang Enhua Zhou Huangan Wu | 2010 | Neural Regeneration Research2010，5，16： | 6 |
| 7 | Effects of electroacupuncture on c-Fos expression in the spinal cord and brain of rats with chronic visceral hypersensitivity显示文摘BACKGROUND:Visceral hypersensitivity is the main cause of irritable bowel syndrome.c-Fos is a marker of visceral hypersensitivity in the central nervous system.Electroacupuncture can relieve chronic visceral hypersensitivity in rats,but the mechanism is still unknown. OBJECTIVE:To identify c-Fos expression in the spinal cord and cerebral cortex of rats with chronic visceral hypersensitivity,and to test the effects of electroacupuncture on pain sensitivity in rats with chronic visceral hypersensitivity. DESIGN,TIME AND SETTING:A randomized controlled animal experiment was performed at the Animal Experimental Center,Shanghai University of Traditional Chinese Medicine,from January to April,2007. MATERIALS:A total of 24 neonatal,male,Sprague Dawley rats,aged five days old,were equally and randomly assigned into a normal group,a model group,and an electroacupuncture group. Rabbit anti-rat c-Fos antibody and Evision secondary antibody kits(Sigma,USA),diaminobenzidine kit(Dako,Denmark),and an LD202H electroacupuncture apparatus(Huawei,Beijing,China) were used in this study. METHODS:Neonatal rats from the model and electroacupuncture groups were used to establish rat models of chronic visceral hypersensitivity by the saccule stimulation method.After model establishment,0.25 mm diameter electric needles were inserted into Tianshu(ST 25) and Shangjuxu(ST37) at a depth of approximately 0.5 cm,with an square wave(alternating current frequency at 100/20 Hz,amplitude ranged 0.2-0.6 ms,intensity at 1 mA) once for 20 minutes,once a day,for seven days.Rats in the normal and model groups were not treated. MAIN OUTCOME MEASURES:Following 7 days of treatment,c-Fos expression in the spinal cord and cerebral cortex was detected by immunohistochemistry.After the first electroacupuncture treatment,abdominal withdrawal reflex scores were investigated to evaluate the pain threshold for chronic visceral hypersensitivity in rats. RESULTS:Visceral hypersensitivity increased c-Fos staining(P<0.05),and electroacupuncture significantly decreased the number of these cells to near normal levels(P>0.05).Abdominal withdrawal reflex scores were significantly lower in the electroacupuncture and normal groups than in the model group(P<0.05) and were similar between the electroacupuncture and normal groups (P>0.05). CONCLUSION:Electroacupuncture decreases c-Fos expression in the spinal cord and cerebral cortex and increases pain threshold in a chronic visceral hypersensitivity model in rats. | Xiaomei Wang Huirong Liu Guanghong Ding Yunfei Chen Huangan Wu Na Li Enhua Zhou Xiudi Qin Lingsong Yuan | 2009 | Neural Regeneration Research2009，4，5： | 4 |
| 8 | Evaluation of human epidermal growth factor receptor 2 status of breast cancer using preoperative multidetector computed tomography with deep learning and handcrafted radiomics features显示文摘Objective:To evaluate the human epidermal growth factor receptor 2(HER2)status in patients with breast cancer using multidetector computed tomography(MDCT)-based handcrafted and deep radiomics features.Methods:This retrospective study enrolled 339 female patients(primary cohort,n=177;validation cohort,n=162)with pathologically confirmed invasive breast cancer.Handcrafted and deep radiomics features were extracted from the MDCT images during the arterial phase.After the feature selection procedures,handcrafted and deep radiomics signatures and the combined model were built using multivariate logistic regression analysis.Performance was assessed by measures of discrimination,calibration,and clinical usefulness in the primary cohort and validated in the validation cohort.Results:The handcrafted radiomics signature had a discriminative ability with a C-index of 0.739[95%confidence interval(95%CI):0.661-0.818]in the primary cohort and 0.695(95%CI:0.609-0.781)in the validation cohort.The deep radiomics signature also had a discriminative ability with a C-index of 0.760(95%CI:0.690-0.831)in the primary cohort and 0.777(95%CI:0.696-0.857)in the validation cohort.The combined model,which incorporated both the handcrafted and deep radiomics signatures,showed good discriminative ability with a C-index of 0.829(95%CI:0.767-0.890)in the primary cohort and 0.809(95%CI:0.740-0.879)in the validation cohort.Conclusions:Handcrafted and deep radiomics features from MDCT images were associated with HER2 status in patients with breast cancer.Thus,these features could provide complementary aid for the radiological evaluation of HER2 status in breast cancer. | Xiaojun Yang Lei Wu Ke Zhao Weitao Ye Weixiao Liu Yingyi Wang Jiao Li Hanxiao Li Xiaomei Huang Wen Zhang Yanqi Huang Xin Chen Su Yao Zaiyi Liu Changhong Liang | 2020 | Chinese Journal of Cancer Research2020，32，2： | 4 |
| 9 | Testosterone attenuates pulmonary epithelial inflammation in male rats of COPD model through preventing NRF1-derived NF-κB signaling显示文摘Testosterone deficiency is common in male patients with chronic obstructive pulmonary disease (COPD) and may correlate with the deterioration of COPD. Clinical research suggests that testosterone replacement therapy may slow the COPD progression, but the specific biological pathway remains unclear. In this study, we explored the effect of testosterone on pulmonary inflammation in male COPD rats. The animals were co-treated with lipopolysaccharide (LPS) and cigarette to induce COPD. In COPD rats, nuclear respiratory factor 1 (NRF1) and NF-κB p65 were upregulated. In cigarette smoke extract (CSE)-, LPS-, or the combination of CSE and LPS-treated L132 cells, NRF1 and p65 were also upregulated. Silencing NRF1 resulted in the downregulation of p65. ChIP‒seq, ChIP‒qPCR, and luciferase results showed that NRF1 transcriptionally regulated p65. Both male and female COPD rats showed an upregulated NRF1 level and similar pulmonary morphology. But NRF1 was further upregulated in male castrated rats. Further supplementing testosterone in castrated male rats significantly reduced NRF1, pulmonary lesions, and inflammation. Supplementation of testosterone also reduced the phosphorylation of p65 and IKKβ induced by LPS or CSE in L132 cells. Our results suggest that testosterone plays a protective role in pulmonary epithelial inflammation of COPD through inhibition of NRF1-derived NF-κB signaling and the phosphorylation of p65. | Xueting Wang Linlin Huang Shan Jiang Kang Cheng Dan Wang Qianqian Luo Xiaomei Wu Li Zhu | 2021 | Journal of Molecular Cell Biology2021，13，2： | 4 |

| 11 | An in situ ATR-FTIR study of mixed collectors BHA/DDA adsorption in ilmenite-titanaugite flotation system显示文摘This paper researched the enhanced flotation separation performance of ilmenite and titanaugite using the mixed collector benzhydroxamic acid/dodecylamine(BHA/DDA).The interface assembly mechanism was mainly investigated through in situ attenuated total reflectance Fourier transform infrared(ATRFTIR)spectroscopy combined with the two-dimensional correlation spectroscopy(2D-COS)and X-ray photoelectron spectroscopy(XPS).It has been found that BHA/DDA mixed collectors successfully separate ilmenite from titanaugite at a molar ratio of 8:1.Zeta potential experiments suggested that,in the presence of mixed collector system,the BHA-DDA complex adsorbed on the ilmenite surface via the chemically adsorbed BHA and the electrostatically adsorbed DDA,however,the complex adsorbed on the surface of titanaugite unstably.According to in situ ATR-FTIR combined with 2D-COS and XPS results,the interface assembly mechanism of BHA/DDA is summarized as:the function group of BHA molecules first binds to the metal sites on minerals to form bidentate ligand,then DDA co-adsorbed with BHA on the surface of minerals through hydrogen bonding.DDA may change the adsorption modes of some BHA on the ilmenite surface from four-membered ring to five-membered ring,while the modes on the titanaugite surface is true opposite.Finally,recommended adsorption configurations of the BHA/DDA complex on the two mineral surfaces are proposed. | Liping Luo Houqin Wu Longhua Xu Jinping Meng Jiahui Lu Huan Zhou Xiaomei Huo Lingyun Huang | 2021 | International Journal of Mining Science and Technology2021，31，4： | 4 |
| 12 | Suspended moxibustion at Tianshu (ST25) inhibits prokineticin 1 and prokineticin receptor 1 expression in the spinal cord of rats with chronic visceral hypersensitivity显示文摘Suspended moxibustion can decrease the expression of prokineticin 1 and its receptor in colonic tissue from rats modeling chronic visceral hyperalgesia. This study aimed to verify if rat spinal cord prokineticin 1 and its receptor contribute to the analgesic effect of suspended moxibustion in a rat model of irritable bowel syndrome where rats display chronic visceral hypersensitivity. Results showed that suspended moxibustion at Tianshu (ST25) point significantly decreased visceral sensitivity to colorectal distention in a chronic visceral hyperalgesia rat model; also protein and mRNA expression of prokineticin 1 and prokineticin receptor 1 in the spinal cord of rats was significantly decreased. Experimental findings indicate that prokineticin 1 and prokineticin receptor 1 are involved in the analgesia using suspended moxibustion in rats with chronic visceral hyperalgesia. | Chen Zhao Li Qit Luyi Wu Tao Yi Huangan Wu Xinxin Guo Cili Zhou Huirong Liu Xiaomei Wang | 2012 | Neural Regeneration Research2012，7，15： | 4 |
| 13 | Negative association of time in range and urinary albumin excretion rate in patients with type 2 diabetes mellitus:a retrospective study of inpatients显示文摘Background:Time in range(TIR)refers to the time an individual spends within their target glucose range,which now has been popularized as an important metric to classify glycemic management and also recognized as an important outcome of current diabetes therapies.This study aimed to investigate the association between TIR and the severity of the urinary albumin excretion rate(UAER)in patients with type 2 diabetes mellitus(T2DM).Methods:We retrospectively analyzed the data of 1014 inpatients with T2DM at the Department of Endocrinology and Metabolism of Peking University International Hospital,China.TIR was defined as the percentage of blood glucose within the target range of 3.90-10.00 mmol/L.Urine samples for assessment of UAER were collected for 3 consecutive days from the start of hospitalization.Results:The TIR values for patients with normal urine levels of albumin,microalbuminuria,and macroalbuminuria were 70%±20%,50%±20%,and 30%±20%,respectively(allP<0.001).The patients were stratified according to quartiles of TIR as follows:quartile(Q)1,<55%;Q2,55%-72%;Q3,73%-83%;and Q4,>83%.The incidences of microalbuminuria in Q1,Q2,Q3,and Q4 were 41.1%,21.6%,7.1%,and 5.5%(allP<0.001),respectively.The respective incidences of macroalbuminuria were 24.2%,1.1%,1.4%,and 0%(allP<0.001).In multinomial logistic regression analyses,TIR was significantly correlated with microalbuminuria(odds ratio[OR]0.58,95%confidence interval[CI]:0.52-0.65,P<0.001)and macroalbuminuria(OR 0.26,95%CI:0.18-0.38,P<0.001)after adjusting for age,sex,body mass index,diabetes duration,systolic blood pressure,and levels of triglycerides,glycosylated hemoglobin A1c,and creatinine.Conclusion:The proportion of blood glucose in TIR is closely related to the severity of UAER in patients with T2DM. | Sanbao Chai Shanshan Wu Sixu Xin Ning Yuan Jianbin Sun Xiaomei Zhang Linong Ji | 2022 | Chinese Medical Journal2022，，9： | 3 |
| 14 | Applications and challenges for single-bacteria analysis by flow cytometry显示文摘Flow cytometry(FCM)is a powerful technique for single-bacteria analysis via simultaneous light-scattering and fluorescence measurements.By offering high-throughput,quantitative,and multiparameter analysis at the single-cell level,FCM has gained an increased popularity in microbiological research,food safety monitoring,water quality control,and clinical diagnosis.Here we will review the recent applications of flow cytometry in areas such as(1)total bacterial cell count,(2)bacterial viability analysis,(3)specific bacterial detection and identification,(4)characterization of physiological changes under environmental perturbations,and(5)biological function studies.Nevertheless,despite these widespread applications,challenges still remain for the detection of small sizes of bacteria and biochemical features that cannot be brightly stained via fluorescence.Recent improvement in FCM instrumentation will be discussed,and particularly the development of high sensitivity flow cytometry for advanced analysis of single bacterial cells will be highlighted. | lina wu shuo wang yiyi song xu wang xiaomei yan | 2016 | Science China Chemistry2016，59，1： | 3 |
| 15 | Inverted Perovskite Solar Cells Based on Small Molecular Hole Transport Material C8-Dioctylbenzothienobenzothiophene显示文摘Summary of main observation and conclusion The small organic molecular Dioctylbenzothienobenzothiophene(C8-BTBT)has been explored as hole transport material(HTM)to replace PEDOT:PSS in inverted perovskite solar cells(PVSCs).MAPbl3 perovskite films depositd onto C8-BTBT are smooth and uniform,with negligible residual of Pbl2 and large grain size even larger than 1μm.Our champion C8-BTBT based devices reached a high power conversion efficiency(PCE)of 15.46%with marginal hysteresis,much higher than that of 11.50%achieved using PEDOT:PSS.Besides,devices adopting C8-BTBT as substrate show superior stability compared with the PEDOT:PSS based devices when stored under ambient conditions with a relative humidity of(25+5)%. | Xiaomei Lian Jiehuan Chen Yingzhu Zhang Gang Wu Hongzheng Chen | 2019 | Chinese Journal of Chemistry2019，37，12： | 3 |
| 16 | Spermine protects intestinal barrier integrity through ras-related C3 botulinum toxin substrate 1/phospholipase C-γ1 signaling pathway in piglets显示文摘Weaning stress can cause tight junctions damage and intestinal permeability enhancement,which leads to intestinal imbalance and growth retardation,thereby causing damage to piglet growth and development.Spermine can reduce stress.However,the mechanism of spermine modulating the intestinal integrity in pigs remains largely unknown.This study aims to examine whether spermine protects the intestinal barrier integrity of piglets through ras-related C3 botulinum toxin substrate 1(Rac1)/phospholipase C-g1(PLC-γ1)signaling pathway.In vivo,80 piglets were categorised into 4 control groups and 4 spermine groups(10 piglets per group).The piglets were fed with normal saline or spermine at 0.4 mmol/kg BW for 7 h and 3,6 and 9 d.In vitro,we investigated whether spermine protects the intestinal barrier after a tumor necrosis factor a(TNF-a)challenge through Rac1/PLC-γ1 signaling pathway.The in vivo study found that spermine supplementation increased tight junction protein mRNA levels and Rac1/PLC-γ1 signaling pathway gene expression in the jejunum of piglets.The serum D-lactate content was significantly decreased after spermine supplementation(P<0.05).The in vitro study found that 0.1 mmol/L spermine increased the levels of tight junction protein expression,Rac1/PLC-γ1 signaling pathway and transepithelial electrical resistance,and decreased paracellular permeability(P<0.05).Further experiments demonstrated that spermine supplementation enhanced the levels of tight junction protein expression,Rac1/PLC-γ1 signaling pathway and transepithelial electrical resistance,and decreased paracellular permeability compared with the NSC-23766 and U73122 treatment with spermine after TNF-a challenge(P<0.05).Collectively,spermine protects intestinal barrier integrity through Rac1/PLC-γ1 signaling pathway in piglets. | Guangmang Liu Xiaomei Xu Caimei Wu Gang Jia Hua Zhao Xiaoling Chen Gang Tian Jingyi Cai Jing Wang | 2022 | Animal Nutrition2022，，1： | 2 |
| 17 | Immobilization of acetylcholinesterase on functionalized SBA-15 mesoporous molecular sieve for detection of organophosphorus and carbamate pesticide显示文摘The immobilization of acetylcholinesterase(AChE) on amino functionalized SBA-15 mesoporous sieves(NH_2-SBA-15) was explored for detection of organophosphorus and carbamate pesticides. Several methods have been studied and the 'adsorption-crosslinking' is found to be the best one. Firstly, AChE and bovine serum albumin(BSA) were adsorbed in turn on the surface of NH_2-SBA-15 by electrostatic adsorption, and then glutaraldehyde was added for cross-linking the amino group of AChE. The NH_2-SBA-15 showed around 95% immobilization efficiency and the specific activity of immobilized AChE(ACh ENH_2-SBA-15) reached 130% relative to free AChE under optimal immobilization conditions. It was found ACh E-NH_2-SBA-15 retained 94.0% and 82.8% of its initial activity after 60 days at 4℃ and 25℃,respectively. It remained 55.0% of its initial activity after 6 times recycling. During the detection of pesticide, the AChE-NH_2-SBA-15 showed wider linear range and much lower limit of detection compared with free AChE. The current method showed good recovery(93.8%-109.3%) and low RSD(<5%) for both standard solution and real vegetable samples of Carbaryl and Trichlorfon. It was believed that AChE-NH_2-SBA-15 could be exploited as a fast, sensitive and low-cost biocatalyst towards the detection of pesticides residues which could be stored at room temperature for a long time. | Yin Rui Xiaomei Wu Baodi Ma Yi Xu | 2018 | Chinese Chemical Letters2018，29，9： | 2 |
| 18 | Effect of Jiaji electroacupuncture in transected rat spinal cord显示文摘We evaluated the effect of Jiaji electroacupuncture on cell proliferation and the expression of markers of endogenous neural stem cell activation after complete spinal cord transection. Female Wistar rats were assigned to 4 groups (n = 24 each): a sham-operated group, a control group, a Jiaji electroacupuncture group, and a Jiaji electroacupuncture preconditioning group. Motor function was significantly improved in the acupuncture groups compared to the control group at 7 and 14 d. Numbers of bromodeoxyuridine (BrdU)-, nestin-, and glial fibrillary acidic protein (GFAP)-positive cells were significantly greater in the acupuncture groups than in the controls at each time point. Expression of nestin and GFAP mRNA was significantly higher in the acupuncture groups than in the controls at each time point. Thus, Jiaji electroacupuncture and preconditioning may promote the proliferation of endogenous neural stem cells after spinal cord transection. | XiuYing Teng DeSheng Wang XiaoMei Zhang ZengJiao Lai HaiXia Jiang JianLi Wu Huan Qi Qian Yu Shun Yao WenBo Song et al. | 2012 | Chinese Science Bulletin2012，57，7： | 2 |
| 19 | Performance of CO_2 absorption in a diameter-varying spray tower显示文摘The application of spray towers for CO_2 capture is a development trend in recent years. However, most of the previous jobs were conducted in a cylindrical tower by using a single spray nozzle, whose configuration and performance is not good enough for industrial application. To solve this problem, the present work proposed a diameter-varying spray tower and a new spray mode of dual-nozzle opposed impinging spray to enhance the heat and mass transfer of CO_2 absorption process. Experiments were performed to investigate the mass transfer performance (in terms of the CO_ 2 removal rate (η) and the overall mass transfer coefficient (K_Ga_e)) of the improved spray tower under various operating conditions. Experimental results showed that the liquid to gas ratio and mole ratio of MEA to CO_2 are major factors, which affect the absorption performance and the maximums of η and (K_Ga_e that are 94.0% and 0.574 kmol·m^(-3)·h^(-1)·kP a^(-1), respectively, under the experimental conditions. Furthermore, new correlations to predict the mass transfer coefficient of the proposed spray tower are developed in various CO_2 concentrations with a Pearson Correlation Coefficient over 90%. | Xiaomei Wu Yunsong Yu Zhen Qin Zaoxiao Zhang | 2017 | Chinese Journal of Chemical Engineering2017，25，8： | 2 |
