1Geochronology and petrogenesis of granitic rocks in Gangdese batholith, southern Tibet显示文摘Based on petrological and geochemical characteristics such as rock assemblage, petrogeochemistry, Sr-Nd isotope, zircon U-Pb age, and Hf isotope, we studied geochronological framework, magma types, source characters, and petrogenesis of different stages of magmatism of the granitic rocks from the Gangdese batholith in southern Tibet. The magmatic activities of the Gangdese batholith can be divided into three stages. The Mesozoic magmatism, induced by northern subduction of Neotethyan slab, was continuously developed, with two peak periods of Late Jurassic and Early Cretaceous. The Paleocene-Eocene magmatism was the most intensive, and resulted from a complex progress of Neotethyan oceanic slab, including subduction, rollback, and subsequent breakoff. And the Oligocene-Miocene magmatism was attributed to the convective removal of thickened lithosphere in an east-west extension setting after India-Asia collision. Isotopically, zircons from these granitic rocks are characterized by positive εHf(t) values, suggesting that the magmatic source of the Gangdese batholith might be an arc terrane, which was accreted to the southern margin of Asia during Late Paleozoic. Therefore, the chronological framework and Hf isotopic characteristics of the Gangdese batholith are distinct from the granitic rocks in adjacent areas, which can be served as a powerful tracer in studying source-to-sink relation of sediments during the uplift and erosion of Tibetan Plateau.JI WeiQiang WU FuYuan LIU ChuanZhou CHUNG SunLin 2009Science China Earth Sciences2009,52,9:89
2Highly fractionated granites:Recognition and research显示文摘Granite is one of the most important components of the continental crust on our Earth; it thus has been an enduring studied subject in geology. According to present knowledge, granite shows a great deal of heterogeneity in terms of its texture,structure, mineral species and geochemical compositions at different scales from small dike to large batholith. However, the reasons for these variations are not well understood although numerous interpretations have been proposed. The key point of this debate is whether granitic magma can be effectively differentiated through fractional crystallization, and, if so, what kind of crystallization occurred during the magmatic evolution. Although granitic magma has high viscosity because of its elevated SiO2 content, we agree that fractional crystallization is effectively processed during its evolution based on the evidence from field investigation,mineral species and its chemical variations, and geochemical compositions. These data indicate that crystal settling by gravitation is not the only mechanism dominating granitic differentiation. On the contrary, flow segregation or dynamic sorting may be more important. Accordingly, granite can be divided into unfractionated, fractionated(including weakly fractionated and highly fractionated) and cumulated types, according to the differentiation degree. Highly fractionated granitic magmas are generally high in primary temperature or high with various volatiles during the later stage, which make the fractional crystallization much easier than the common granitic melts. In addition, effective magmatic differentiation can be also expected when the magma emplaced along a large scale of extensional structure. Highly fractionated granitic magma is easily contaminated by country rocks due to its relatively prolonged crystallization time. Thus, granites do not always reflect the characteristics of the source areas and the physical and chemical conditions of the primary magma. We proposed that highly fractionated granites are an important sign indicating compositional maturity of the continental crust, and they are also closely related to the rare-elemental(metal) mineralization of W,Sn, Nb, Ta, Li, Be, Rb, Cs, REEs, etc.WU FuYuan LIU XiaoChi JI WeiQiang WANG JiaMin YANG Lei 2017Science China Earth Sciences2017,60,7:109
3The Chinese Society of Clinical Oncology(CSCO):clinical guidelines for the diagnosis and treatment of gastric cancer显示文摘China is one of the countries with the highest incidence of gastric cancer.There are differences in epidemiological characteristics,clinicopathological features,tumor biological characteristics,treatment patterns,and drug selection between gastric cancer patients from the Eastern and Western countries.Non-Chinese guidelines cannot specifically reflect the diagnosis and treatment characteristics for the Chinese gastric cancer patients.The Chinese Society of Clinical Oncology(CSCO)arranged for a panel of senior experts specializing in all sub-specialties of gastric cancer to compile,discuss,and revise the guidelines on the diagnosis and treatment of gastric cancer based on the findings of evidence-based medicine in China and abroad.By referring to the opinions of industry experts,taking into account of regional differences,giving full consideration to the accessibility of diagnosis and treatment resources,these experts have conducted experts’consensus judgement on relevant evidence and made various grades of recommendations for the clinical diagnosis and treatment of gastric cancer to reflect the value of cancer treatment and meeting health economic indexes.This guideline uses tables and is complemented by explanatory and descriptive notes covering the diagnosis,comprehensive treatment,and follow-up visits for gastric cancer.Feng-Hua Wang Lin Shen Jin Li Zhi-Wei Zhou Han Liang Xiao-Tian Zhang Lei Tang Yan Xin Jing Jin Yu-Jing Zhang Xiang-Lin Yuan Tian-Shu Liu Guo-Xin Li Qi Wu Hui-Mian Xu Jia-Fu Ji Yuan-Fang Li Xin Wang Shan Yu Hao Liu Wen-Long Guan Rui-Hua Xu 2019Cancer Communications2019,39,1:127
4Genome-wide analysis of heat shock transcription factor families in rice and Arabidopsis显示文摘The heat shock transcription factors (HSFs) are the major heat shock factors regulating the heat stress response. They participate in regulating the expression of heat shock proteins (HSPs), which are critical in the protection against stress damage and many other important biological processes. Study of the HSF gene family is important for understanding the mechanism by which plants respond to stress. The completed genome sequences of rice (Oryza sativa) and Arabidopsis (Arabidopsis thaliana) constitute a valuable resource for comparative genomic analysis, as they are representatives of the two major evolutionary lineages within the angiosperms: the monocotyledons and the dicotyledons. The identification of phylogenetic relationships among HSF proteins in these species is a fundamental step to unravel the functionality of new and yet uncharacterized genes belonging to this family.In this study, the full complement of HSF genes in rice and Arabidopsis has probably been identified through the genome-wide scan. Phylogenetic analyses resulted in the identification of three major clusters of orthologous genes that contain members belonging to both species, which must have been represented in their common ancestor before the taxonomic splitting of the angiosperms. Further analysis of the phylogenetic tree reveals a possible dicot specific gene group. We also identified nine pairs of paralogs, as evidence for studies on the evolution history of rice HSF family and rice genome evolution. Expression data analysis indicates that HSF proteins are widely expressed in plants. These results provide a solid base for future functional genomic studies of the HSF gene family in rice and Arabidopsis.Jingkang Guo Jian Wu Qian Ji Chao Wang Lei Luo Yi Yuan Yonghua Wang Jian Wang 2008Journal of Genetics and Genomics2008,35,2:52
5Fast-track surgery could improve postoperative recovery in radical total gastrectomy patients显示文摘AIM: To assess the impact of fast-track surgery (FTS) on hospital stay, cost of hospitalization and complications after radical total gastrectomy. METHODS: A randomized, controlled clinical trial was conducted from November 2011 to August 2012 in the Department of Digestive Surgery, Xijing Hospital of Digestive Diseases, the Fourth Military Medical University. A total of 122 gastric cancer patients who met the selection criteria were randomized into FTS and conventional care groups on the first day of hospitalization. All patients received elective standard D2 total gastrectomy. Clinical outcomes, including duration of flatus and defecation, white blood cell count, postoperative pain, duration of postoperative stay, cost of hospitalization and complications were recorded and evaluated.Two specially trained doctors who were blinded to the treatment were in charge of evaluating postoperative outcomes, discharge and follow-up. RESULTS: A total of 119 patients finished the study, including 60 patients in the conventional care group and 59 patients in the FTS group. Two patients were excluded from the FTS group due to withdrawal of consent. One patient was excluded from the conventional care group because of a non-resectable tumor. Compared with the conventional group, FTS shortened the duration of flatus (79.03 ± 20.26 hvs 60.97 ± 24.40 h, P = 0.000) and duration of defecation (93.03 ± 27.95 h vs 68.00 ± 25.42 h, P = 0.000), accelerated the decrease in white blood cell count [P < 0.05 on postoperative day (POD) 3 and 4], alleviated pain in patients after surgery (P < 0.05 on POD 1, 2 and 3), reduced complications (P < 0.05), shortened the duration of postoperative stay (7.10 ± 2.13 dvs 5.68 ± 1.22 d,P = 0.000), reduced the cost of hospitalization (43783.25 ± 8102.36 RMBvs 39597.62 ± 7529.98 RMB,P = 0.005), and promoted recovery of patients. CONCLUSION: FTS could be safely applied in radical total gastrectomy to accelerate clinical recovery of gastric cancer patients.Fan Feng Gang Ji Ji-Peng Li Xiao-Hua Li Hai Shi Zheng-Wei Zhao Guo-Sheng Wu Xiao-Nan Liu Qing-Chuan Zhao 2013World Journal of Gastroenterology2013,19,23:44
6A prospective randomized trial of transnasal ileus tube vs nasogastric tube for adhesive small bowel obstruction显示文摘AIM:To study the therapeutic efficacy of a new transnasal ileus tube advanced endoscopically for adhesive small bowel obstruction.METHODS:A total of 186 patients with adhesive small bowel obstruction treated from September 2007 to February 2011 were enrolled into this prospective randomized controlled study.The endoscopically advanced new ileus tube was used for gastrointestinal decompression in 96 patients and ordinary nasogastric tube(NGT) was used in 90 patients.The therapeutic efficacy was compared between the two groups.RESULTS:Compared with the NGT group,the ileus tube group experienced significantly shorter time for relief of clinical symptoms and improvement in the findings of abdominal radiograph(4.1 ± 2.3 d vs 8.5 ± 5.0 d) and laboratory tests(P < 0.01).The overall effectiveness rate was up to 89.6% in the ileus tube group and 46.7% in the NGT group(P < 0.01).And 10.4% of the patients in the ileus tube group and 53.3% of the NGT group underwent surgery.For recurrent adhesive bowel obstruction,ileus tube was also significantly more effective than NGT(95.8% vs 31.6%).In the ileus tube group,the drainage output on the first day and the length of hospital stay were significantly different depending on the treatment success or failure(P < 0.05).The abdominal radiographic improvement was correlated with whether or not the patient underwent surgery.CONCLUSION:Ileus tube can be used for adhesive small bowel obstruction.Endoscopic placement of the ileus tube is convenient and worthy to be promoted despite the potential risks.Xiao-Li Chen Feng Ji Qi Lin Yi-Peng Chen Jian-Jiang Lin Feng Ye Ji-Ren Yu Yi-Jun Wu 2012World Journal of Gastroenterology2012,18,16:46
7Relationship between co-stimulatory molecule B7-H3 expression and gastric carcinoma histology and prognosis显示文摘AIM:To investigate the expression of co-stimulatorymolecule B7-H3 in gastric carcinoma and adenomatissue as well as normal gastric tissue and to explore therelationship between B7-H3 expression and pathologicalfeatures and prognosis of gastric carcinoma.METHODS:B7-H3 expression was detected in 102samples of human gastric carcinoma and 10 samples ofgastric adenoma and 10 samples of normal gastric tissueby immunohistochemical assay.Correlation betweenthe expression of B7-H3 and the patients'age,sex,gastric carcinoma locus,tumor size,tissue type,tumorinfiltration depth,differentiation degree,lymph nodemetastasis,and survival time was analyzed.RESULTS:B7-H3 was expressed in all gastric adenomasamples and in 58.8% samples of gastric carcinoma.B7-H3 expression in gastric carcinoma samples wasnot related with the patients'age,sex,lymph nodemetastasis,and tumor size(P>0.05),but with thesurvival time,infiltration depth of tumor and tissue type.CONCLUSION:Detection of B7-H3 expression in gastriccarcinoma tissue is beneficial to the judgment of theprognosis of gastric carcinoma patients and the choice oftreatment.Chang-Ping Wu Jing-Ting Jiang Min Tan Yi-Bei Zhu Mei Ji Kuan-Feng Xu Jie-Min Zhao Guang-Bo Zhang Xue-Guang Zhang 2006World Journal of Gastroenterology2006,12,3:38
8Multiple pathogenic factor-induced complications of cirrhosis in rats: A new model of hepatopulmonary syndrome with intestinal endotoxemia显示文摘AIM: To develop and characterize a practical model of Hepatopulmonary syndrome (HPS) in rats. METHODS: The experimental animals were randomized into five feeding groups: (1) control (fed standard diet), (2) control plus intraperitoneal injection with lipopolysaccharide (LPS), (3) cirrhosis (fed a diet of maize flour, lard, cholesterol, and alcohol plus subcutaneously injection with carbon tetrachloride (CCl4) oil solution), (4) cirrhosis plus LPS, and (5) cirrhosis plus glycine and LPS. The blood, liver and lung tissues of rats were sampled for analysis and characterization. Technetium 99m-labeled macroaggregated albumin (Tc99m-MAA) was used to test the dilatation of pulmonary microvasculature. RESULTS: Typical cirrhosis and subsequent hepato- pulmonary syndrome was observed in the cirrhosis groups after an 8 wk feeding period. In rats with cirrhosis, there were a decreased PaO2 and PaCO2 in arterial blood, markedly decreased arterial O2 content, a significantly increased alveolar to arterial oxygen gradient, an increased number of bacterial translocated within mesenteric lymph node, a signifi cant higher level of LPS and tumor necrosis factor-α (TNF-α) in plasma, and a signifi cant greater ratio of Tc99m-MAA brain-over- lung radioactivity. After LPS administration in rats withcirrhosis, various pathological parameters got worse and pulmonary edema formed. The predisposition of glycine antagonized the effects of LPS and signif icantly alleviated various pathological alterations. CONCLUSION: The results suggest that: (1) a characte- ristic rat model of HPS can be non-invasively induced by multiple pathogenic factors including high fat diet, alcohol, cholesterol and CCl4; (2) this model can be used for study of hepatopulmonary syndrome and is clinically relevant; and (3) intestinal endotoxemia (IETM) and its accompanying cytokines, such as TNF-α, exert a crucial role in the pathogenesis of HPS in this model.Hui-Ying Zhang De-Wu Han Zhong-Fu Zhao Ming-She Liu Yan-Jun Wu Xian-Ming Chen Cheng Ji 2007World Journal of Gastroenterology2007,13,25:37

12A Positioning System based on Communication Satellites and the Chinese Area Positioning System(CAPS)显示文摘The Chinese Area Positioning System(CAPS) is a positioning system based on satellite communication that is fundamentally different from the 3'G'(GPS,GLONASS and GALILEO) systems.The latter use special-purpose navigation satellites to broadcast navi-gation information generated on-board to users,while the CAPS transfers ground-generated navigation information to users via the communication satellite.In order to achieve accurate Positioning,Velocity and Time(PVT),the CAPS employs the following strategies to over-come the three main obstacles caused by using the communication satellite:(a) by real-time following-up frequency stabilization to achieve stable frequency;(b) by using a single carrier in the transponder with 36 MHz band-width to gain sufficient power;(c) by incorporating Decommissioned Geostationary Orbit communication satellite(DGEO),barometric pressure and Inclined Geostationary Orbit communication satellite(IGSO) to achieve the 3-D posi-tioning.Furthermore,the abundant transponders available on DGEO can be used to realize the large capacity of communication as well as the integrated navigation and communication.With the communication functions incorporated,five new functions appear in the CAPS:(1) combination of navigation and communication;(2) combination of navigation and high accu-racy orbit measurement;(3) combination of navigation message and wide/local area differen-tial processing;(4) combination of the switching of satellites,frequencies and codes;and(5) combination of the navigation message and the barometric altimetry.The CAPS is thereby labelled a PVT5C system of high accuracy.In order to validate the working principle and the performance of the CAPS,a trial system was established in the course of two years at a cost of about 20 million dollars.The trial constellation consists of two GEO satellites located at E87.5° and E110.5°,two DGEOs located at E130° and E142°,as well as barometric altimetry as a virtual satellite.Static and dynamic performance tests were completed for the Eastern,the Western,the Northern,the Southern and the Middle regions of China.The evaluation results are as follows:(1) land static test,plane accuracy range:C/A code,15~25m;P code,5~10 meters;altitude accuracy range,1~3 m;(2) land dynamic test,plane accuracy range,C/A code,15~25m;P code,8~10m;(3) velocity accuracy,C/A code,0.13~0.3ms-1,P code,0.15~0.17ms-1;(4) timing accuracy,C/A code,160ns,P code,13 ns;(5) timing compared accuracy of Two Way Satellite Time and Frequency Transfer(TWSTFT),average accuracy,0.068ns;(6) random error of the satellite ranging,10.7 mm;(7) orbit determination accuracy,better than 2 m.The above stated random error is 1σ error.At present,this system is used as a preliminary operational system and a complete system with 3 GEO,3 DGEO and 3 IGSO is being established.Guo-Xiang Ai Hu-Li Shi Hai-Tao Wu Yi-Hua Yan Yu-Jing Bian Yong-Hui Hu Zhi-Gang Li Ji Guo Xian-De Cai 2008Chinese Journal of Astronomy and Astrophysics2008,8,6:33
13Artesunate synergizes with sorafenib to induce ferroptosis in hepatocellular carcinoma显示文摘Sorafenib is the first-line medication for advanced hepatocellular carcinoma(HCC),but it can only extend limited survival.It is imperative to find a combination strategy to increase sorafenib efficacy.Artesunate is such a preferred candidate,because artesunate is clinically well-tolerated and more importantly both drugs can induce ferroptosis through different mechanisms.In this study we investigated the combined effect of sorafenib and artesunate in inducing ferroptosis of HCC and elucidated the involved molecular mechanisms.We showed that artesunate greatly enhanced the anticancer effects of low dose of sorafenib against Huh7,SNU-449,and SNU-182 HCC cell lines in vitro and against Huh7 cell xenograft model in Balb/c nude mice.The combination index method confirmed that the combined effect of sorafenib and artesunate was synergistic.Compared with the treatment with artesunate or sorafenib alone,combined treatment induced significantly exacerbated lipid peroxidation and ferroptosis,which was blocked by N-acetyl cysteine and ferroptosis inhibitors liproxstatin-1 and deferoxamine mesylate,but not by inhibitors of other types of cell death(z-VAD,necrostatin-1 and belnacasan).In Huh7 cells,we demonstrated that the combined treatment induced oxidative stress and lysosome-mediated ferritinophagy,two essential aspects of ferroptosis.Sorafenib at low dose mainly caused oxidative stress through mitochondrial impairments and SLC7A11-invovled glutathione depletion.Artesunate-induced lysosome activation synergized with sorafenib-mediated pro-oxidative effects by promoting sequential reactions including lysosomal cathepsin B/L activation,ferritin degradation,lipid peroxidation,and consequent ferroptosis.Taken together,artesunate could be repurposed to sensitize sorafenib in HCC treatment.The combined treatment can be easily translated into clinical applications.Zhong-jie Li Hui-qi Dai Xiao-wei Huang Ji Feng Jing-huan Deng Zi-xuan Wang Xiao-mei Yang Yu-jia Liu Yong Wu Pan-hong Chen Huan Shi Ji-gang Wang Jing Zhou Guo-dong Lu 2021Acta Pharmacologica Sinica2021,42,2:31
14Case-based learning in education of Traditional Chinese Medicine: a systematic review显示文摘OBJECTIVE:To assess the effect of case-based learning(CBL)in the education of Traditional Chinese Medicine(TCM).METHODS:The studies concerning TCM courses designed with CBL were included by searching the databases of EBSCO,Pubmed,Science Citation Index,China National Knowledge Infrastructure,Chongqing VIP database.The valid data was extracted in accordance with the included criteria.The quality of the studies was assessed with Gemma Flores-Masteo.RESULTS:A total of 22 articles were retrieved that met the selection criteria:one was of high quality;two were of low quality;the rest were categorized as moderate quality.The majority of the studiesdemonstrated the better effect produced by CBL,while a few studies showed no difference,compared with the didactic format.All included studies confirmed the favorable effect on learners'attitude,skills and ability.CONCLUSION:CBL showed the desirable results in achieving the goal of learning.Compared to didactic approach,it played a more active role in promoting students'competency.Since the quality of the articles on which the study was based was not so high,the findings still need further research to become substantiated.Ji Chen Ying Li Yong Tang Fang Zeng Xi Wu Fanrong Liang 2013Journal of Traditional Chinese Medicine2013,33,5:30
15Lung transplantation in China between 2015 and 2018显示文摘Background:Lung transplantation(LT)has been demonstrated as the only effective therapy for patients with end-stage lung diseases.Increasing listed lung transplant candidates and expanding volumes of lung transplant centers across China require wellorganized programs and registry data collection based on the large population.This study aimed to summarize and analyze the data of LT development in China.Methods:We retrospectively collected and analyzed data from the China Lung Transplantation Registry(CLuTR).Key data were reported from the registry with transplant types,indications,donor and recipient characteristics,outcomes and survival.The survival<30 days,1-year and 3-year survival rates were estimated with risk factors identified.Results:CLuTR contained data from 1053 lung transplants performed through January 1st,2015 to December 31st,2018 reported by 18 registered transplant centers.The largest category of diagnosis before transplantation was idiopathic interstitial pneumonitis.The total<30 days,1-year and 3-year survival rates in CLuTR were 81.45%,70.11%,and 61.16%with discrepancy by indications.Large proportion of recipients who were more than 60 years old required higher standard of care.Infection-related complications resulted in more death events in the early post-surgery periods.New York Heart Association grading at listing,extra-corporeal membrane oxygenation usage peri-transplantation,allograft dysfunction(primary graft dysfunction>Grade 0),renal insufficiency(estimated glomerular filtration rate<60 mL min_11.73 m^2),were independently associated with a higher risk for 3-year mortality in the entire cohort.Conclusions:Facing more end-stage of lung diseases and comorbidities,this study analyzed the outcomes and survival of LT recipients in China.Further prospectively stratified analyses with longer follow-up will be needed.Chun-Xiao Hu Wen-Hui Ghen Jian-Xing He Ge-Ning Jiang Xiao-Shan Li Dong Wei Bo Wu Ji Zhang Chen Wang Jing-Yu Chen 2019Chinese Medical Journal2019,,23:25

18Virus-related liver cirrhosis: Molecular basis and therapeutic options显示文摘Chronic infections with hepatitis B virus(HBV)and/or hepatitis C virus(HCV)are the major causes of cirrhosis globally.It takes 10-20 years to progress from viral hepatitis to cirrhosis.Intermediately active hepatic inflammation caused by the infections contributes to the inflammation-necrosis-regeneration process,ultimately cirrhosis.CD8+T cells and NK cells cause liver damage via targeting the infected hepatocytes directly and releasing pro-inflammatory cytokine/chemokines.Hepatic stellate cells play an active role in fibrogenesis via secreting fibrosis-related factors.Under the inflammatory microenvironment,the viruses experience mutationselection-adaptation to evade immune clearance.However,immune selection of some HBV mutations in the evolution towards cirrhosis seems different from that towards hepatocellular carcinoma.As viral replication is an important driving force of cirrhosis pathogenesis,antiviral treatment with nucleos(t)ide analogs is generally effective in halting the progression of cirrhosis,improving liver function and reducing the morbidity of decompensated cirrhosis caused by chronic HBV infection.Interferon-αplus ribavirin and/or the direct acting antivirals such as Vaniprevir are effective for compensatedcirrhosis caused by chronic HCV infection.The standard of care for the treatment of HCV-related cirrhosis with interferon-αplus ribavirin should consider the genotypes of IL-28B.Understanding the mechanism of fibrogenesis and hepatocyte regeneration will facilitate the development of novel therapies for decompensated cirrhosis.Ji Lin Jian-Feng Wu Qi Zhang Hong-Wei Zhang Guang-Wen Cao 2014World Journal of Gastroenterology2014,20,21:24
19Experimental and clinical study of influence of high-frequency electric surgical knives on healing of abdominal incision显示文摘瞄准:在腹壁切口愈合上学习高周波的电的外科的刀的影响。方法:240 只白鼠被划分成 10 (0 ) , 10 (2 ) , 10 (5 ) ,并且 10 (8 ) 组和腹部手术的老鼠模型被分别地使用电的外科的刀和普通口针劝诱。然后,他们分别地被给生理盐水和 0.2 mL 的皮下注射在 10 的集中(2 ) 的埃希氏杆菌属关口 i,葡萄球菌 aureus 和绿脓假单胞菌的量的混合, 10 (5 ) 并且 10 (8 ) 。根据动物实验,经历腹部手术(上面的类型 II ) 的 220 个病人随机被分配进跟随三个组之一:电热刀(EK, 93 个盒子) ,电凝法(EC, 55 个盒子) 并且控制(72 个盒子) 。高周波的电的外科的刀习惯于为在 EK 的血壅滞的腹的纸巾和电凝法组织的 dissect。普通口针和电凝法在 EC 组被使用。普通口针和系住的丝缝线在控制被使用。结果:在除了组 10 的所有组(0 ) ,电的外科的刀做的 incisional 创伤的感染率与普通口针比那显著地高。而且,在组有有效差量 10 (2 ) , 10 (5 ) ,并且 10 (8 )(P<0.05 ) ,然而并非(0 )(P>0.05 ) 在组, 10 在 EK 和 EC 之间组织。临床的研究显示出在控制组在 EK,在 EC 的 11 个盒子(16.36%) 和 2 个盒子(2.86%) 在 16 种情况(17.20%) 中愈合的一处推迟的创伤。在 EK 和控制之间的有效差量组织(chi2 = 8.57, P<0.01 ) ,并且在 EC 和控制组之间(chi2 = 5.66, P<0.05 ) 被观察,然而并非在 EK 和 EC 之间(chi2 = 0.017, P>0.05 ) 。结论:高周波的电的刀可以显著地推迟腹壁切口愈合。它的申请应该被最小化以便减少手术后的复杂并发症的可能性。Guang-Wei Ji Yuan-Zhi Wu Xu Wang Hua-Xiong Pan Ping Li Wan-Ying Du Zhi Qi An Huang Li-Wei Zhang Li Zhang Wen Chen Guang-Hua Liu Hui Xu Quan Li Ai-Hua Yuan Xiao-Ping He Guo-Hua Mei 2006World Journal of Gastroenterology2006,12,25:23
20Anti-inflammatory effect of Diammonium Glycyrrhizinate in a rat model of ulcerative colitis显示文摘瞄准:为了探索 Diammonium 的反煽动性的机制,在 ulcerative 的一个老鼠模型的 Glycyrrhizinate 由乙酸导致了。方法:Spragur-Dawley 雌老鼠被划分成四个组:Diammonium Glycyrrhizinate 组,地塞米松组,乙酸控制和正常控制组。结肠的发炎被疾病活动索引,粗野词法损坏,组织学的损害和结肠的 myeloperoxidase 活动评估。Immunohistochemistry 被用来在结肠的粘膜检测 NF-kappaB, TNF-alpha 和 ICAM-1 的表示。结果:把控制,显示出的两 Diammonium Glycyrrhizinate 和地塞米松比作乙酸重要反煽动性的效果(P < 0.01 ) 。在结肠的粘膜的 NF-kappaB, TNF-alpha 和 ICAM-1 的表示比在乙酸组在 Diammonium Glycyrrhizinate 组和地塞米松组是显著地更低的。结论:Diammonium Glycyrrhizinate 能在 ulcerative 的一个老鼠模型减少煽动性的损害。这可以在结肠的粘膜经由 NF-kappaB, TNF-alpha 和 ICAM-1 的抑制发生。Hao Yuan Wan-Sheng Ji Ke-Xiang Wu Jian-Xin Jiao Liang-Hua Sun Yong-Tang Feng 2006World Journal of Gastroenterology2006,12,28:23
