| 2 | Study of the mechanisms of acupuncture and moxibustion treatmentfor ulcerative colitis ratsinview of the gene expression of cytokines显示文摘AIM To observe the effect of acupuncture and moxibustion on the expression of IL 1β and IL 6 mRNA in ulcerative colitis rats. METHODS The SD rat ulcerative colitis model was created by immunological method associated with local stimulation. Colonic mucosa was prepared from human fresh surgical colonic specimens, homogenized by adding appropriate amount of normal saline and centrifuged at 3000*!r/*!min . The supernatant was collected for measurement of protein conentration and then mixed with Freund adjuvant. This antigen fluid was first injected into the plantae of the model group rats, and then into their plantae, dorsa, inguina and abdominal cavities (no Freund adjuvant for the last injection) again on the 10th, 17th, 24th and 31st day. When a certain titer of serum anti colonic antibody was reached, 2% formalin and antigen fluid (no Freund adjuvant) were administered separately by enema. The ulcerative colitis rat model was thus set up. The animals were randomly divided into four groups: model control group (MC, n =8), electro acupuncture group (EA, n =8), herbs partition moxibustion group (HPM 8), normal control group (NC, n =8). HPM: Moxa cones made of refined mugwort floss were placed on the medicinal pad (medicinal pad dispensing: Radix Aconiti praeparata, cortex Cinnamomi, etc ) for Qihai (RN 6) and Tianshu (ST 25, bilateral) and ignited. Two moxa cones were used for each acupoint once a day and 14 times in all. EA: Tianshu (bilateral) and Qihai were stimulated by the intermittent pulse with 2Hz frequency, 4mA intensity for 20 minutes once a day and 14 times in all. After treatment, rats of all four groups were killed simultaneously. The spleen was separated and the distal colon was dissected. Total tissue RNA was isolated by the guanidinium thiocyanate phenol chloroform extraction method. RT PCR technique was used to study the expression of IL 1β and IL 6 mRNA. RESULTS IL 1β and IL 6 mRNAs were not detected in the spleen and colonic mucosa of the NC rats, whereas they were significantly expressed in that of the MC rats. IL 1β and IL 6 mRNAs were markedly lower in the EA and HPM rats than that in MC rats. There was no significant difference between the levels of IL 1β and IL 6 mRNAs in the EA and HPM rats. The expressions of IL 1β and IL 6 mRNAs were nearly the same in the spleen and colon of all groups. CONCLUSION Acupuncture and moxibustion greatly inhibited the expression of IL 1β and IL 6 mRNA in the experimental ulcerative colitis rats. | Wu HG Zhou LB Pan YY Huang C Chen HP Shi Z Hua XG | 1999 | World Journal of Gastroenterology1999，5，6： | 45 |
| 3 | Up-regulation of PIK3CA promotes metastasis in gastric carcinoma显示文摘AIM:To explore expressions of PIK3CA in the progression of gastric cancer from primary to metastasis and its effects on activation of phosphatidylinositol 3-kinase(PI3K)/Akt pathway.METHODS:mRNA and protein levels of PIK3CA were assessed,respectively,by real-time quantitative polymerase chain reaction and immunohistochemistry in specimens of normal gastric mucosa,primary foci and lymph node and distant metastasis of gastric cancer.Akt and phosphorylated Akt protein were also examined by Western blotting in these tissues,in order to analyze the effect of PIK3CA expression level changes on the activation of PI3K/Akt signaling pathway.RESULTS:PIK3CA mRNA in lymph node metastasis were approximately 5 and 2 folds higher,respectively,than that in the corresponding normal gastric mucosa and primary gastric cancer tissues(P<0.05),while no statistical significance was found compared with distant metastasis.Immunohistochemically,PIK3CA protein expression was discovered in 7(35%)specimens of 20 primary foci vs 10(67%)of 15 of lymph node metastasis or 11(61%)of 18 of distant metastasis(35%vs 67%,P=0.015;35%vs 61%,P=0.044).With the increased level of PIK3CA expression,the total Akt protein expression remained almost unchanged,but p-Akt protein was upregulated markedly.CONCLUSION:Increased expression of PIK3CA is expected to be a promising indicator of metastasis in gastric cancer.Up-regulation of PIK3CA may promote the metastasis of gastric cancer through aberrant activation of PI3K/Akt signaling. | Liu JF Zhou XK Chen JH Yi G Chen HG Ba MC Lin SQ Qi YC. | 2010 | World Journal of Gastroenterology2010，16，39： | 20 |
| 4 | CT arterial portography and CT hepatic arteriography in detection of micro liver cancer显示文摘AIM To recognize the characteristic findings of micrQliver cancer (MLC) and to evaluate the effect of CT arterial portography (CTAP) and CT hepatic arteriography (CTHA) in diagnosis of MLC. METHODS Between April 1996 to December 1998, CTAP and CTHA were performed in 12patients with MLC, which were not detect ed byconventional CT examinations. After CTHA, 3 mL-- 5 mL mixture of lipiodol, doxorubic in andmitomycin C were injected into hepatic arterythrough the catheter, and then followed up by CTthree or four weeks later (Lipiodol CT LP-CT).RESULTS A total of 22 micro--tumors (0 .2 cm 0.6 cm in diameter ) were detected in 12patients, which manifested as small perfusiondefects in CTAP and small round enhancement inCTHA. The rate of detectability of CTAP andCTHA was 68.2% (15/ 22) and 77.3% (17/ 22)respectively, and the rate of the simultaneoususe of both procedures reached 86. 4% (19/ 22 ).All micro--tumors were demonstrated as punctatelipiodol deposit fool in LP--CT. After LP--CT, theelevated serum level of Q-fetoprotein (AFP)dropped to the normal level in all patients.CONCLUSION The CTAP and CTHA are the mostsensitive imaging methods for detecting microIiver cancer. Confirmed by the change of theelevated serum AFP level and lipiodol depositfool in LP-CT, small perfusion defects in CTAPand punctate enhancement in CTHA may suggestmicro--liver cancer. | Li L Wu PH Mo YX Lin HG Zheng L Li JQ Lu LX Ruan CM Chen L | 1999 | World Journal of Gastroenterology1999，5，3： | 16 |

| 6 | Iron and non-alcoholic fatty liver disease显示文摘The mechanisms that promote liver injury in non-alcoholic fatty liver disease(NAFLD) are yet to be thoroughly elucidated. As such, effective treatment strategies are lacking and novel therapeutic targets are required. Iron has been widely implicated in the pathogenesis of NAFLD and represents a potential target for treatment. Relationships between serum ferritin concentration and NAFLD are noted in a majority of studies, although serum ferritin is an imprecise measure of iron loading. Numerous mechanisms for a pathogenic role of hepatic iron in NAFLD have been demonstrated in animal and cell culture models. However, the human data linking hepatic iron to liver injury in NAFLD is less clear, with seemingly conflicting evidence, supporting either an effect of iron in hepatocytes or within reticulo-endothelial cells. Adipose tissue has emerged as a key site at which iron may have a pathogenic role in NAFLD. Evidence for this comes indirectly from studies that have evaluated the role of adipose tissue iron with respect to insulin resistance. Adding further complexity, multiple strands of evidence support an effect of NAFLD itself on iron metabolism. In this review, we summarise the human and basic science data that has evaluated the role of iron in NAFLD pathogenesis. | Laurence J Britton V Nathan Subramaniam Darrell HG Crawford | 2016 | World Journal of Gastroenterology2016，22，36： | 14 |
| 7 | 牛津单髁膝关节置换:长期结果(英文)显示文摘牛津膝置换是使用最广泛的膝关节单髁置换(UKR)。牛津膝在37年前开始应用,拥有一个全匹配的活动衬垫,因而磨损率非常低。牛津膝最主要的使用指征是膝关节前内侧骨关节炎,这种病人至少占所有需要行膝关节置换术患者的50%。由于这一系统的设计特点,传统UKR的反指征,如年龄、活动量、肥胖、髌股关节损害和软骨钙质沉着症等对于牛津膝均不是反指征。与全膝关节置换(TKR)相比,牛津膝提供更快的康复、更好的功能、更大的活动度和更好的术后满意度,发生并发症更少、程度更轻,病残率和死亡率更低。一个持续超过30年的研究显示在90%的病例中,牛津膝为患者终生提供了优或良的临床结果,且不需要翻修。在最近15年,牛津膝通过微创手术入路植入,涉及6000多例使用该入路牛津膝置换的9个研究报道显示,10年生存率约95%。在许多这样的研究中,医生们在拟行膝关节置换的患者中约50%使用了牛津单髁膝置换。 | DW Murray BE Marks L Kontochristos CAF Dodd HG Pandit | 2013 | 中华关节外科杂志(电子版)2013，7，4： | 9 |

| 9 | Systematic mechanism-orientated approach to chronic pancreatitis pain显示文摘Pain in chronic pancreatitis(CP) shows similarities with other visceral pain syndromes(i.e.,inflammatory bowel disease and esophagitis),which should thus be managed in a similar fashion.Typical causes of CP pain include increased intrapancreatic pressure,pancreatic inflammation and pancreatic/extrapancreatic complications.Unfortunately,CP pain continues to be a major clinical challenge.It is recognized that ongoing pain may induce altered central pain processing,e.g.,central sensitization or pro-nociceptive pain modulation.When this is present conventional pain treatment targeting the nociceptive focus,e.g.,opioid analgesia or surgical/endoscopic intervention,often fails even if technically successful.If central nervous system pain processing is altered,specific treatment targeting these changes should be instituted(e.g.,gabapentinoids,ketamine or tricyclic antidepressants).Suitable tools are now available to make altered central processing visible,including quantitative sensory testing,electroencephalograpy and(functional) magnetic resonance imaging.These techniques are potentially clinically useful diagnostic tools to analyze central pain processing and thus define optimum management approaches for pain in CP and other visceral pain syndromes.The present review proposes a systematic mechanism-orientated approach to pain management in CP based on a holistic view of the mechanisms involved.Future research should address the circumstances under which central nervous system pain processing changes in CP,and how this is influenced by ongoing nociceptive input and therapies.Thus we hope to predict which patients are at risk for developing chronic pain or not responding to therapy,leading to improved treatment of chronic pain in CP and other visceral pain disorders. | Stefan AW Bouwense Marjan de Vries Luuk TW Schreuder Soren S Olesen Jens B Frokjær Asbjorn M Drewes Harry van Goor Oliver HG Wilder-Smith | 2015 | World Journal of Gastroenterology2015，21，1： | 6 |

| 12 | 全内关节镜下距腓骨前韧带修复后附加下伸肌支持带增强术对慢性踝关节不稳的治疗是没有必要的显示文摘近年来,随着关节镜器械和技术的不断发展,镜下踝关节韧带修复受到广泛关注。该技术可分为关节镜辅助下伸肌支持带(IER)增强术和关节镜下距腓前韧带(ATFL)修复术。采用关节镜技术治疗慢性踝关节不稳(CAI),ATFL解剖修复被认为是关键步骤然时,是否需要附加IER增强术目前存在争议。有研究报道关节镜下ATFL修复联合IER增强术后的良好结果,代价是显著增加了手术时间和难度。此外,由于IER的解剖起点位于跟腓骨韧带前方10 mm处,1ER增强术并非严格意义上的解剖修复,可能会增加术后关节活动受限的风险。 | 唐尧(编译) 唐康来(编译) Lee SH Cho HG Yang JH | 2021 | 中华医学杂志2021，101，41： | 5 |
| 13 | 口服华法令应用指南(对2005年第三版的修订)显示文摘英国血液学标准委员会(The British Committee for Standards in Haematology,BCSH)于1998年发表了第三版口服抗凝药物用药指南。当2005年6月修订时,委员们认为第三版的绝大多数推荐仍然是实用的,无需发行第四版。然而委员们也注意到一些关于抗凝的新资料。像原来版本中口服抗凝药物这一术语在此次修订中指的是口服维生素K拮抗剂(vitamin K Antagonists,VKA),如华法令。新的非维生素K拮抗剂正处于临床试验中,还没有被批准使用。当这些药物能用于临床时,将出版针对这些药物应用指南。此指南的对象是与治疗抗凝患者有关的卫生保健人员。 | Baglin TP Keeling DM Watson HG 苏燕华(编译) 王兆钺(审校) | 2006 | 国际输血及血液学杂志2006，29，6： | 4 |

| 16 | 显示文摘The phase formation regularities in nanometer powders of ternary alloys prepared by gas evaporation process with induction current as the heating source were investigated. Al-Cu-Mn and Al-Cu-Cr were chosen as the samples in this study. The experimental results show that the necessary conditions for forming ternary compound phases in a ternary alloy nanometer powder are that they must be able to form in a conventional bulk alloy. To obtain a ternary compound phase in nanometer powders, composition of the master alloy must be in a certain range. Changing the composition of the master alloy and evaporation temperature can control the kinds of the phases and their relative amount in the alloy nanometer powders. In present study, AlMn, Al8Mn5 and AlCu2Mn phases formed in as-prepared nanometer powders of Al-Cu-Mn alloy, and the highest relative amount of AlCu2Mn phase is about 99%. In nanometer powders of Al-Cu-Cr alloy,Cu9Al4, Al2Cu3, AlCr2 and Al13Cr2 phases formed without any ternary compound phase. | Yan, HG Chen, ZH Kang, ZT Chen, G Hunag, PY | 2001 | 中国有色金属学会会刊:英文版2001，11，6： | 3 |
| 17 | 核仁组织者区与核仁显示文摘术语和定义用现代的术语可以下这样的定义:核仁组织者区(NOR)就是含有主要rRNA基因(18S和28S的rDNA)的一个染色体区段。核仁是间或细胞内由于NOR中基因的活动而形成的可见结构。也就是说,NOR是染色体中的一段,核仁是由这段染色体再加上在NOR周围累积的物质一主要是rRNA和它们的前体以及特殊的核糖体蛋白质共同形成的结构。 | Schwarzacher HG Wachtler F 范耀山 | 1984 | 国际遗传学杂志1984，27，2： | 3 |
