| 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 |

| 4 | Status monitoring and health assessment of Luhuitou fringing reef of Sanya, Hainan, China显示文摘The monitoring survey and health assessment for benthic community were carried out in Luhuitou fringing reef of Sanya, Hainan, China in 2002. Monitoring survey included manta tow, line intercept transect, video transect and digital photograph. The mean live coral cover was 23.40%. Comparison of used monitoring methods showed that video transect can replace line intercept transect, and 50 m transect is better than 20 m transect in uneven coral region. Survey data and comparison with previous research work showed that Luhuitou fringing reef has been damaged severely and has a general declining trend with live coral cover from about 85% in the 1960s down to 20% in 2004, but it still has quite high biodiversity and therefore has special protection value. Main factors of Luhuitou fringing reef declining were human activities including reef rock digging and curios collecting, destructive fishing, sediment and pollutant from coastal land, and recent marine aquaculture. Only strengthening integrated management can reach improvement and restoration of Luhuitou declining coral reef ecosystem. | ZHANG Qiaomin SHI Qi CHEN Gang FONG T C W WONG D C C HUANG Hui WANG Hankui ZHAO Meixia | 2006 | Chinese Science Bulletin2006,51,B12: | 15 |
| 5 | Design of TRIP Steel With High Welding and Galvanizing Performance in Light of Thermodynamics and Kinetics显示文摘A new type of transformation induced plasticity (TRIP) steel with not only high strength and high ductility but also superior welding and galvanizing properties was designed and developed recently. Low carbon and low silicon content were preliminarily selected with the aim of meeting the requirements of superior quality in both welding and galvanizing. Phosphorus was chosen as one of the alloying elements, because it could reduce carbon activity in cementite and increase the stability of austenite. In addition, the possibility of phosphorus segregating at grain boundary was also discussed by thermodynamics as well as kinetics. Phase diagram was estimated at high temperature and the composition of the steel was then selected in the hyperperitectic range to avoid problems, which might occur in sheet steel continuous casting. Phase diagram in the inter-critical temperature was estimated for the steel to obtain the starting temperature of fast cooling. For understanding the minimum rate of fast cooling, pearlite growth kinetics was calculated with self-developed diffusion coefficients of elements in grain boundary. Overaging temperature was determined through the calculation of T0 temperature by both equilibrium and para-equilibrium assumptions, which was different from the current determination, which is only based on an equilibrium estimation. | LI Lin DE COOMAN B C LIU Ren-dong VLEUGELS j ZHANG Mei SHI Wen | 2007 | Journal of Iron and Steel Research(International)2007,14,6: | 13 |

| 9 | Thermal Stability of Retained Austenite in TRIP Steel After Different Treatments显示文摘Thermal decomposition of retained austenite in TRIP steel was investigated by means of differential scanning calorimetry(DSC).The decomposition curve was abnormal,and the decomposition temperature and the activation energy were measured by the Kissinger method,which were all higher than those in quenched steel.The thermal decomposition data of samples soaked in liquid nitrogen after TRIP treatment were all similar to those without additional low temperature treatment.It indicated that there is a high thermal stability in retained austenite of the TRIP steel at low temperature,which was also proved by XRD analysis. | SHI Wen LI Lin Bruno C De Cooman Patrick Wollants YANG Chun-xia | 2008 | Journal of Iron and Steel Research(International)2008,15,1: | 5 |
| 10 | 塞内加尔病毒特异性重组分析揭示了塞尼卡病毒聚合酶保真性与病毒重组发生的相关性显示文摘塞尼卡病毒(SVA)是一种新出现的感染猪并可导致仔猪死亡的病毒。最近的研究显示,SVA在猪体内可发生重组,表明了重组在SVA进化过程中的重要性。越来越多的研究表明,病毒聚合酶保真性的改变能显著降低病毒的毒力,而且病毒聚合酶也是影响病毒重组的主要因素。因此,通过提高病毒聚合酶的保真性获得重组缺陷病毒株、不但具有重要的理论价值,作为可使减毒株更加安全的技术手段、也具有疫苗开发的应用价值。由于微RNA病毒科的病毒均具有高度的变异性和复杂性,通过提升病毒聚合酶的保真性、结合其它减毒策略,可获得足够安全和有效的减毒活疫苗候选毒株。 | Li C Wang H Shi J | 2019 | 中国预防兽医学报2019,41,5: | 5 |
| 11 | Lymph node ratio and preoperative CA 19-9 levels predict overall survival and recurrence-free survival in patients with resected pancreatic adenocarcinoma显示文摘AIM:Clinicopathologic factors predicting overall survival (OS) would help identify a subset to benefit from adjuvant therapy. METHODS: One hundred and sixty-nine patients patients from 1984 to 2009 with curative resections for pancreatic adenocarcinoma were included. Tumors were staged by American Joint Committee on Cancer 7th edition criteria. Univariate and multivariable analyses were performed using Kaplan-Meier methodology or Cox proportional hazard models. Log-rank tests were performed. Statistical inferences were assessed by two-sided 5% significance level. RESULTS: Median age was 67.1 (57.2-73.0) years with equal gender distribution. Tumors were in the head (89.3%) or body/tail (10.7%). On univariate analysis, adjuvant therapy, lymph node (LN) ratio, histologic grade, negative margin status, absence of peripancreatic extension, and T stage were associated with improved OS. Adjuvant therapy, LN ratio, histologic grade, number of nodes examined, negative LN status, and absence of peripancreatic extension were associated with improved recurrence-free survival (RFS). On multivariable analysis, LN ratio and carbohydrate antigen (CA) 19-9 levels were associated with OS. LN ratio was associated with RFS. CONCLUSION: The LN ratio and CA 19-9 levels are independent prognostic factors following curative resections of pancreatic cancer. | Sabrina C Wentz Zhi-Guo Zhao Yu Shyr Chan-Juan Shi Kay Washington Nipun B Merchant Fen Xia A Bapsi Chakravarthy | 2012 | World Journal of Gastrointestinal Oncology2012,4,10: | 3 |
