1Astragalus mongholicus ameliorates renal fibrosis by modulating HGF and TGF-β in rats with unilateral ureteral obstruction显示文摘Astragalus mongholicus(AM) derived from the dry root of Astragalus membranaceus Bge.var.mongolicus(Bge.) Hsiao is a widely used traditional Chinese medicine.The present study investigated the potential role of AM on renal fibrosis on a rat model of unilateral ureteral obstruction(UUO).We divided 48 Sprague-Dawley rats randomly into 4 groups:sham-operated group(Sham),untreated UUO group,AM-treated(10 g/(kg·d)) UUO group,and losartan-treated(20 mg/(kg·d)) UUO group as positive control.Haematoxylin & eosin(HE) and Masson staining were used to study the dynamic histological changes of the kidneys 7 and 14 d after operation.The expressions of fibronectin(FN),type I collagen(colI),hepatocyte growth factor(HGF),transforming growth factor-β1(TGF-β1),and α-smooth muscle actin(α-SMA) were analyzed by real-time polymerase chain reaction(PCR),immunohistochemistry staining,and Western blot.Results show that,similar to losartan,AM alleviated the renal damage and decreased the deposition of FN and colI from UUO by reducing the expressions of TGF-β1 and α-SMA(P<0.05),whereas HGF increased greatly with AM treatment(P<0.05).Our findings reveal that AM could retard the progression of renal fibrosis.The renoprotective effect of AM might be related to inhibition of myofibroblast activation,inducing of HGF and reducing of TGF-β1 expression.Chuan ZUO Xi-sheng XIE Hong-yu QIU Yao DENG Da ZHU Jun-ming FAN 2009Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2009,10,5:15
2A two-step lineage reprogramming strategy to generate functionally competent human hepatocytes from fibroblasts显示文摘Terminally differentiated cells can be generated by lineage reprogramming,which is,however,hindered by incomplete conversion with residual initial cell identity and partial functionality. Here, we demonstrate a new reprogramming strategy by mimicking the natural regeneration route, which permits generating expandable hepatic progenitor cells and functionally competent human hepatocytes. Fibroblasts were first induced into human hepatic progenitor-like cells (hHPLCs), which could robustly expand in vitro and efficiently engraft in vivo. Moreover, hHPLCs could be efficiently induced into mature human hepatocytes (hiHeps) in vitro, whose molecular identity highly resembles primary human hepatocytes (PHHs). Most importantly, hiHeps could be generated in large quantity and were functionally competent to replace PHHs for drug-metabolism estimation, toxicity prediction and hepatitis B virus infection modeling. Our results highlight the advantages of the progenitor stage for successful lineage reprogramming. This strategy is promising for generating other mature human cell types by lineage reprogramming.Bingqing Xie Da Sun Yuanyuan Du Jun Jia Shicheng Sun Jun Xu Yifang Liu Chengang Xiang Sitong Chen Huangfan Xie Qiming Wang Guangya Li Xuehui LYU Hui Shen Shiyu Li Min Wu Xiaonan Zhang Yue Pu Kuanhui Xiang Weifeng Lai Peng Du Zhenghong Yuan Cheng Li Yan Shi Shichun Lu Hongkui Deng 2019Cell Research2019,29,9:9
3Effects of early oral feeding after radical total gastrectomy in gastric cancer patients显示文摘BACKGROUND Gastric cancer(GC)is a heavy burden in China.Nutritional support for GC patients is closely related to postoperative rehabilitation.However,the role of early oral feeding after laparoscopic radical total gastrectomy in GC patients is unclear and high-quality research evidence is scarce.AIM To prospectively explore the safety,feasibility and short-term clinical outcomes of early oral feeding after laparoscopic radical total gastrectomy for GC patients.METHODS This study was a prospective cohort study conducted between January 2018 and December 2019 based in a high-volume tertiary hospital in China.A total of 206 patients who underwent laparoscopic radical total gastrectomy for GC were enrolled.Of which,105 patients were given early oral feeding(EOF group)after surgery,and the other 101 patients were given the traditional feeding strategy(control group)after surgery.Perioperative clinical data were recorded and analyzed.The primary endpoints were gastrointestinal function recovery time and postoperative complications,and the secondary endpoints were postoperative nutritional status,length of hospital stay and expenses,etc.RESULTS Compared with the control group,patients in the EOF group had a significantly shorter postoperative first exhaust time(2.48±1.17 d vs 3.37±1.42 d,P=0.001)and first defecation time(3.83±2.41 d vs 5.32±2.70 d,P=0.004).In addition,the EOF group had a significant shorter postoperative hospitalization duration(5.85±1.53 d vs 7.71±1.56 d,P<0.001)and lower postoperative hospitalization expenses(16.60±5.10 K¥vs 21.00±7.50 K¥,P=0.014).On the 5th day after surgery,serum prealbumin level(214.52±22.47 mg/L vs 204.17±20.62 mg/L,P=0.018),serum gastrin level(246.30±57.10 ng/L vs 223.60±55.70 ng/L,P=0.001)and serum motilin level(424.60±68.30 ng/L vs 409.30±61.70 ng/L,P=0.002)were higher in the EOF group.However,there was no significant difference in the incidence of total postoperative complications between the two groups(P=0.507).CONCLUSION Early oral feeding after laparoscopic radical total gastrectomy can promote the recovery of gastrointestinal function,improve postoperative nutritional status,reduce length of hospital stay and expenses while not increasing the incidence of related complications,which indicates its safety,feasibility and potential benefits for gastric cancer patients.Yi-Xun Lu Yan-Jun Wang Tian-Yu Xie Shuo Li Di Wu Xiong-Guang Li Qi-Ying Song Li-Peng Wang Da Guan Xin-Xin Wang 2020World Journal of Gastroenterology2020,26,36:9
4Ectopic expression of soybean GmKNT1 in Arabidopsis results in altered leaf morphology and flower identity显示文摘Plant morphology is specified by leaves and flowers, and the shoot apical meristem (SAM) defines the architecture of plant leaves and flowers. Here, we reported the characterization of a soybean KNOX gene GmKNT1, which was highly homologous to Arabidopsis STM. The GmKNT1 was strongly expressed in roots, flowers and developing seeds. Its expression could be induced by IAA, ABA and JA, but inhibited by GA or cytokinin. Staining of the transgenic plants overexpressing GmKNT1-GUS fusion protein revealed that the GmKNT1 was mainly expressed at lobe region, SAM of young leaves, sepal and carpel, not in seed and mature leaves. Scanning electron micros-copy (SEM) disclosed multiple changes in morphology of the epidermal cells and stigma. The transgenic Arabidopsis plants overexpress-ing the GmKNT1 showed small and lobed leaves, shortened internodes and small clustered inflorescence. The lobed leaves might result from the function of the meristems located at the boundary of the leaf. Compared with wild type plants, transgenic plants had higher ex-pression of the SAM-related genes including the CUP, WUS, CUC1, KNAT2 and KNAT6. These results indicated that the GmKNT1 could affect multiple aspects of plant growth and development by regulation of downstream genes expression.Jun Liu Da Ha Zongming Xie Chunmei Wang Huiwen Wang Wanke Zhang Jinsong Zhang Shouyi Chen 2008Journal of Genetics and Genomics2008,35,7:8
5Role of prophylactic hyperthermic intraperitoneal chemotherapy in patients with locally advanced gastric cancer显示文摘BACKGROUND Gastric cancer is the second most common malignant tumor in China,ranking third among all malignant tumor mortality rates.Hyperthermic intraperitoneal chemotherapy(HIPEC)has been shown to increase significantly the effectiveness of intraperitoneal chemotherapeutic drugs,prolong the action time of these drugs on intraperitoneal tumor cells,and enhance their diffusion in tumor tissues.HIPEC may be one of the best choices for the eradication of residual cancer cells in the abdominal cavity.AIM The aim of this study was to study the role of preventive HIPEC after radical gastrectomy.METHODS A prospective analysis was performed with patients with c T4 N0-3 M0 gastric cancer to compare the effects of postoperative prophylactic HIPEC plus intravenous chemotherapy with those of routine adjuvant chemotherapy.Patients’medical records were analyzed,and differences in the peritoneal recurrence rate,diseasefree survival time,and total survival time between groups were examined.RESULTS The first site of tumor recurrence was the peritoneum in 11 cases in the conventional adjuvant chemotherapy group and in 2 cases in the HIPEC group(P=0.020).The 1-year and 3-year disease-free survival rates were 91.9%and 60.4%,respectively,in the conventional adjuvant chemotherapy group and 92.1%and 63.0%,respectively,in the HIPEC group.The 1-year and 3-year overall survival rates were 95.2%and 66.3%,respectively,in the conventional adjuvant chemotherapy group and 96.1%and 68.6%,respectively,in the HIPEC group.No significant difference in postoperative or chemotherapy complications was observed between groups.CONCLUSION In patients with c T4 N0-3 M0 gastric cancer,prophylactic HIPEC after radical tumor surgery is beneficial to reduce peritoneal tumor recurrence and prolong survival.Tian-Yu Xie Di Wu Shuo Li Zhao-Yan Qiu Qi-Ying Song Da Guan Li-Peng Wang Xiong-Guang Li Feng Duan Xin-Xin Wang 2020World Journal of Gastrointestinal Oncology2020,12,7:7
6Laser direct writing and characterizations of flexible piezoresistive sensors with microstructures显示文摘Functional materials with high viscosity and solid materials have received more and more attentions in flexible pressure sensors,which are inadequate in the most used molding method.Herein,laser direct writing(LDW)method is proposed to fabricate flexible piezoresistive sensors with microstructures on PDMS/MWCNTs composites with an 8%MWCNTs mass fraction.By controlling laser energy,microstructures with different geometries can be obtained,which significantly impacts the performances of the sensors.Subsequently,curved microcones with excellent performance are fabricated under parameters of f=40 kHz and v=150 mm·s^(-1).The sensor exhibits continuous multi-linear sensitivity,ultrahigh original sensitivity of 21.80%kPa^(-1),wide detection range of over 20 kPa,response/recovery time of~100 ms and good cycle stability for more than 1000 times.Besides,obvious resistance variation can be observed when tiny pressure(a peanut of 30 Pa)is applied.Finally,the flexible piezoresistive sensor can be applied for LED brightness controlling,pulse detection and voice recognition.Chenying Zhang Wei Zhou Da Geng Cheng Bai Weida Li Songyue Chen Tao Luo Lifeng Qin Yu Xie 2021Opto-Electronic Advances2021,4,4:7
7Comparative stability analyses of traditional and selective room-and-pillar mining techniques for sub-horizontal tungsten veins显示文摘The stability and productivity concerning a modification on the traditional room and pillar for a new selective technique at the Portuguese Panasqueira Mine have been described.The traditional room-and-pillar stoping uses 5.0-m wide rooms with 3.0 m×3.0 m pillars,while the selective room-and-pillar mining technique consists in stoping with rooms of 4.0 m wide and pillars of 4 m×4 m with a subsequent selective cutting of the quartz veins at the mid pillar of approximately 0.5 m high,to obtain a pillar section with an area of 3.0 m×3.0 m.The stability and productivity analyses indicate that the selective technique obtains smaller average pillar safety factor,more rock mass displacement,more extraction and selectivity ratios,and ore grade improvement,compared with the traditional technique.These results show that the selective technique is also more convenient.This proposed selective room-and-pillar mining technique is applicable to any sub-horizontal narrow quartz veins with wolfram,gold,etc.such as the famous La Rinconada gold mine in the Peruvian Andes.Vidal Felix Navarro Torres Carlos Dinis da Gama Matilde Costa e Silva Paula Falcao Neves Qiang Xie 2011International Journal of Minerals,Metallurgy and Materials2011,18,1:7

9PCDH17 increases the sensitivity of colorectal cancer to 5-fluorouracil treatment by inducing apoptosis and autophagic cell death显示文摘5-Fluorouracil(5-FU)is known as a first-line chemotherapeutic agent against colorectal cancer(CRC),but drug resistance occurs frequently and significantly limits its clinical success.Our previous study showed that the protocadherin 17(PCDH17)gene was frequently methylated and functioned as a tumor suppressor in CRC.However,the relationship between PCDH17 and 5-FU resistance in CRC remains unclear.Here,we revealed that PCDH17 was more highly expressed in 5-FU-sensitive CRC tissues than in 5-FU-resistant CRC tissues,and high expression of PCDH17 was correlated with high BECN1 expression.Moreover,this expression profile contributed to superior prognosis and increased survival in CRC patients.Restoring PCDH17 expression augmented the 5-FU sensitivity of CRC in vitro and in vivo by promoting apoptosis and autophagic cell death.Furthermore,autophagy played a dominant role in PCDH17-induced cell death,as an autophagy inhibitor blocked cell death to a greater extent than the pancaspase inhibitor Z-VAD-FMK.PCDH17 inhibition by siRNA decreased the autophagy response and 5-FU sensitivity.Mechanistically,we showed that c-Jun NH2-terminal kinase(JNK)activation was a key determinant in PCDH17-induced autophagy.The compound SP600125,an inhibitor of JNK,suppressed autophagy and 5-FU-induced cell death in PCDH17-reexpressing CRC cells.Taken together,our findings suggest for the first time that PCDH17 increases the sensitivity of CRC to 5-FU treatment by inducing apoptosis and JNK-dependent autophagic cell death.PCDH17 may be a potential prognostic marker for predicting 5-FU sensitivity in CRC patients.Shuiping Liu Haoming Lin Da Wang Qiang Li Hong Luo Guoxiong Li Xiaohui Chen Yongqiang Li Peng Chen Bingtao Zhai Wengang Wang Ruonan Zhang Bi Chen Mingming Zhang Xuemeng Han Qiujie Li Liuxi Chen Ying Liu Xiaying Chen Guohua Li Yu Xiang Ting Duan Jiao Feng Jianshu Lou Xingxing Huang Qin Zhang Ting Pan Lili Yan Ting Jin Wenzheng Zhang Lvjia Zhuo Yitian Sun Tian Xie Xinbing Sui 2019Signal Transduction and Targeted Therapy2019,4,1:4
10Value of low-dose and optimized-length computed tomography(CT)scan in CT-guided percutaneous transthoracic needle biopsy of pulmonary nodules显示文摘Objective:To investigate the value of application of low-dose and optimized length CT scan on puncture results,complications and patients’radiation dosage during CT-guided percutaneous biopsy of pulmonary nodules(PTNB).Methods:A total of 231 patients with PTNB under CT guidance were collected.Low dose scanning utilized tube current of 20 mA as compared with 40 mA in conventional dosage.Optimized length in CT is defined as intentionally narrowing the range of CT scanning just to cover 25 mm(5 layers)around the target layer during needle adjustment.According to whether low-dose scans and optimized length scans techniques were utilized,patients were divided into three groups:conventional group(conventional sequence+no optimization),optimized length group(conventional sequence+optimized length),and low-dose optimized length group(low dose sequence+optimized length).The ED(effective dose),the DLP(dose length product),the average CTDIvol(Volume CT dose index),total milliampere second between subgroups were compared.Results:Compared with the conventional group,ED,intraoperative guidance DLP,total milliseconds and operation time in the optimized length group were reduced by 18.2%(P=0.01),37%(P=0.003),17.5%(P=0.013)and13.3%(P=0.021)respectively.Compared with the optimized length group,the ED was reduced by 87%,preoperative positioning,intraoperative guidance and postoperative review DLP were also reduced by 88%,total milliampere second was reduced by 79%,with an average CTDIvol was reduced by 86%,in the low-dose optimized length group(P<0.001 for all).Conclusion:Optimizing the length during CT scanning can effectively reduce the intraoperative radiation dose and reduce the operation time compared with conventional plan;low-dose and optimized length CT scan can further reduce the total radiation dose compared with optimized length group with no differences on intraoperative complications,biopsy results and operation time.Hui Yuan Da Li Yan Zhang Xiaozhen Xie Lujun Shen 2021Journal of Interventional Medicine2021,4,3:4
11Hepatic encephalopathy complicated with hyponatremia and acid-base disturbance and its prognosis显示文摘Objective:To improve the diagnosis and therapeutic effect of occurrence and development of hyponatremia and disorder of acid-base balance among patients with hepatic encephalopathy(HE) by elucidating the regularity and mechanism,as well as its influence on prognosis.Methods:327 HE patients admitted to our hospital from January 1990 to June 2010 were enrolled.Meanwhile 316 patients hospitalized in the medical department of the same hospital were chosen as the control group.Patients in both groups were given the same methods to measure arterial blood gas parameters(pH value,PaCO2,[HCO3-],TCO2,BE and SaO2),blood biochemistry([Na+],[K+],[Cl-]),liver function,kidney function and blood glucose,serum sodium,and thereupon tocalculate the anion gap(AG) and the potential [HCO3-],and acid-base balance disorder.Results:Among the 327 HE patients,hyponatremia was found in 188 cases(57.4%),of whom 132 patients died(70.2%).While among the 316 patients in control group,68 presented with hyponatremia(21.5%),and 19 died(27.9%).The incidence and mortality were significantly different between the two groups(P<0.001).All the 327 patients presented with different degrees of acid-base balance disorder and 178 died(54.4%),in whom 164(50.2%) belonged to simple acid-base balance disorder and 74(45.1%) died,136(41.6%) were dual acid-base balance disorder and 80(58.8%) died,27(8.2%) were triple acid-base disturbance and 24(88.9%) died.Whereas in the control group only 83 patients(26.2%) were recognized as simple and dual acid-base balance disorder,and 18(21.7%) died.There was higher incidence of acid-base balance disorder and mortality rate in HE group than control one(P<0.001).Conclusion:Hyponatremia is valuable to judge HE patients' prognosis.The key parameters in the judgment and evaluation on acid-base balance disorder among HE patients are the change of pH values and serum electrolyte values.When pH value ≤ 7.30 or > 7.55,it generally suggests a poor prognosis.Ren Chengshan Wang Lei Zhao Xiaoyan Yang Shiming Zhang Yanqi Wang Xiwen Bo Jianying Zhang Pengbin Guo Hong Ling Xianlong Li Yihui Da Siping Xie Xia Ren Wei Li Chunhua Qian Guisheng 2012Journal of Medical Colleges of PLA(China)2012,27,3:3
12Efficiency and safety evaluation of Baimai ointment for alleviating hypermyotonia following cerebral infarction显示文摘BACKGROUND: Baimai ointment has Shujin and Huoluo efficiency. It has been confirmed by basic pharmacodynamic experiments that Baimai ointment has some therapeutic effects on stroke. However,the detailed evaluations of Baimai ointment on clinically treating stroke patients for function recovery are still insufficient with little reports. OBJECTIVE: To observe the efficiency and safety of Baimai ointment on alleviating hypermyotonia following cerebral infarction DESIGN: A randomized,parallel and controlled experiment. SETTING: Department of Neurology,Beijing Aerospace General Hospital. PARTICIPANTS: A total of 120 patients with acute front-cycle cerebral infarction were selected from Department of Neurology,Beijing Aerospace General Hospital from July to December 2006 and met the diagnosis criteria modified by Forth National Seminar on Cerebrovascular Disease. The experiment had got confirmed consent from local ethic committee. All 120 patients with cerebral infarction were randomly divided into experimental group (n =80; 32 in the acute phase,32 in the recovery phase and 16 in the sequela phase) and control group (n =40; 16 in the acute phase,16 in the recovery phase and 8 in the sequela phase). METHODS: Within 4 weeks after the patients were enrolled in this study,no other traditional Chinese medicines containing similar components were adopted besides routine supporting therapy. The Baimai ointment being consisted of Jianghuang,Roudoukou,Gansong,Yangqishi,Gancao,She,shannai,Zanghuixiang,Zangchangpu,Huajiao and Jianhua was used by trial group (20 g/ampoule,Tibet Lingzhiqizheng Tibetan Drug Factory; batch number: 050403),2–3 times per day,the ointment was moderately coated traveling parts of Baimai. MAIN OUTCOME MEASURES: The evaluation of National Institutes of Health Stroke Scale (NIHSS),Modified Rankin Scale and Modified Ashworth Scale were performed before administration,2 and 4 weeks after administration. RESULTS: All 120 patients with acute front-cycle cerebral infarction were involved in the final analysis. ① Evaluation of therapeutic effects: After 4 weeks,the comparison of overall muscular tension and muscular tension in acute phase between the two groups (acute phase,chronic phase and recovery phase) demonstrated that the experimental group improved significantly (Z =–2.25,–2.06,P < 0.05). After 2 weeks,the change of muscular tension was not significantly different from baseline (P > 0.05). Whereas after 4 weeks,the change of muscular tension in acute phase was significantly different from baseline (P < 0.05); however,the change of muscular tension in recovery phase and sequelae phase was not significantly different from baseline (P > 0.05). After the treatment,the overall NIHSS and disability score of both groups did not change significantly (P > 0.05). ② Adverse reaction and side effect: There were two adverse events in experimental groups. One patient underwent petechia,and the symptom disappeared following stopping medication which did not reappear after remedication. The other patient complained of a pain coming from the place where the medication was used,and the symptom went away without treatment. Two cases of adverse events were not significantly correlated with the usage of medication,so both of which could not be confirmed to be adverse reactions. CONCLUSION: Baimai ointment achieves some therapeutic effects on treating hypermyotonia of cerebral infarction patients,especially significantly preventing the hypermyotonia in acute phase with good safety.Sheng da Liu Chu ming Jiang Dong hua Li Cui peng Xie Jian xin Yan 2007Neural Regeneration Research2007,2,10:2
13Updates on novel pharmacotherapeutics for the treatment of nonalcoholic steatohepatitis显示文摘Nonalcoholic steatohepatitis(NASH)is a progressive form of nonalcoholic fatty liver disease(NAFLD),characterized with hepatocellular steatosis,ballooning,lobular inflammation,fibrotic progression,and insulin resistance.NASH may progress to cirrhosis and hepatocellular carcinoma(HCC),which are the major indications for liver transplantation and the causes for mortality.Thus far,there are no approved pharmacotherapeutics for the treatment of NASH.Given the complexity of NASH pathogenesis at multifaceted aspects,such as lipotoxicity,inflammation,insulin resistance,mitochondrial dysfunction and fibrotic progression,pharmacotherapeutics under investigation target different key pathogenic pathways to gain either the resolution of steatohepatitis or regression of fibrosis,ideally both.Varieties of pharmacologic candidates have been tested in clinical trials and have generated some positive results.On the other hand,recent failure or termination of a few phase II and III trials is disappointing in this field.In face to growing challenges in pharmaceutical development,this review intends to summarize the latest data of new medications which have completed phase II or III trials,and discuss the rationale and preliminary results of several combinatory options.It is anticipated that with improved understanding of NASH pathogenesis and critical endpoints,efficient pharmacotherapeutics will be available for the treatment of NASH with an acceptable safety profile.Yong-yu Yang Li Xie Ning-ping Zhang Da Zhou Tao-tao Liu Jian Wu 2022Acta Pharmacologica Sinica2022,43,5:2
14Progress in development of bioderived materials for dermal wound healing显示文摘Treatment of acute and chronic wounds is one of the primary challenges faced by doctors.Bioderived materials have significant potential clinical value in tissue injury treatment and defect reconstruction.Various strategies,including drug loading,addition of metallic element(s),crosslinking and combining two or more distinct types of materials with complementary features,have been used to synthesize more suitable materials for wound healing.In this review,we describe the recent developments made in the processing of bioderived materials employed for cutaneous wound healing,including newly developed materials such as keratin and soy protein.The focus was on the key properties of the bioderived materials that have shown great promise in improving wound healing,restoration and reconstruction.With their good biocompatibility,nontoxic catabolites,microinflammation characteristics,as well as their ability to induce tissue regeneration and reparation,the bioderived materials have great potential for skin tissue repair.Lin-Cui Da Yi-Zhou Huang Hui-Qi Xie 2017Regenerative Biomaterials2017,4,5:2
15Simulation of drop breakage in liquid–liquid system by coupling of CFD and PBM: Comparison of breakage kernels and effects of agitator configurations显示文摘This work focuses on drop breakage for liquid-liquid system with an adoption of numerical simulation by using computational fluid dynamics and population balance model (PBM) coupled with two-fluid model (TFM). Two different breakage kernels based on identical breakage mechanism but different descriptions of breaking time are take n into account in this work. Eight cases corresp on ding to distinct configurations of agitator are carried out to validate numerical predictions, namely agitators with different porosity and hole diameters, respectively implemented in Cases 1 to 5 and Cases 6 to 8. The results are compared with experimental data for testing the applicability of both kernels. Simulations are implemented, in this work, with an approach of class method for the solution of population balance model by the special-purpose computational fluid dynamics solver Fluent 16.1 based on finite volume method, and the grids used for meshing the solution domain are accomplished in a commercial software Gambit 2.4.6. The effects of configurations of agitator corresponding to different parameters mentioned above on final Sauter mean diameter are equally concentrated in this work. Analysis of both kernels and comparisons with experimental results reveal that, the second kernel has more decent agreement with experiments, and the results of investigations on effects of agitator configurations show that the in fluences of these parameters on Sauter mean diameter are marginal, but appropriate porosity and hole diameter are actually able to decrease Sauter mean diameter. These outcomes allow us to draw general conclusions and help investigate performances of liquid-liquid system.Rui Xie Jun Li Yang Jin Da Zou Ming Chen 2019Chinese Journal of Chemical Engineering2019,27,5:2
16Long-term survival after enucleation of a giant esophagea gastrointestinal stromal tumor显示文摘Gastrointestinal stromal tumors(GISTs) are rare mesenchymal neoplasms of the gastrointestinal tract. Less than 1% occurs in the esophagus. Surgery is the primary treatment for patients with GISTs. We report a29-year-old male was admitted after the detection of a posterior mediastinal mass during work-up with routine examination. He did not have any disease-related symptoms. The physical examination was unremarkable. Chest computed tomographic scan, the barium esophagogram and endoscopic esophageal ultrasound showed benign neoplasm. The patient was performed an enucleation surgery through the right posterolateral thoracotomy. The pathology revealed a 13.0 cm × 12.0cm × 5.0 cm mass. The tumor was CD117(C-kit), PDGFRA and DOG1 positive. These findings were consistent with a GIST of the esophagus. So the diagnosis of GIST of esophagus was confirmed. The pathological diagnosis of low grade of GIST of esophagus was confirmed. The patient has no evidence of recurrence and is in good clinical conditions up-to date, five years after surgery.Zhi-Min Mu Yuan-Cai Xie Xu-Xing Peng Hai Zhang Gang Hui Hao Wu Ji-Xian Liu Bao-Kun Chen Da Wu Yi-Wang Ye 2014World Journal of Gastroenterology2014,20,37:2
