1电动牙刷与手动牙刷对口腔卫生的效果比较显示文摘目的对电动牙刷和手动牙刷在去除菌斑、维护牙龈健康、对色素和牙结石的作用、可靠性、不良作用和成本等进行比较.方法计算机检索Cochrane口腔健康协作组临床试验资料库(截至2004年6月17日)、Cochran临床对照试验中心资料库(Cochrane图书馆2004第2期)、MEDLINE(1966~2004)、EMBASE(1980~2004第2周)和CINAHL(1982~2004第2周),并与制造商联系以获取更多资料.根据下列标准纳入随机对照试验:随机分配研究对象;参加者为手运动无障碍的普通人群;干预措施为无监督的手动或电动牙刷刷牙,至少4周;主要结局指标为试验期间菌斑和牙龈炎的变化.由6个作者独立评价并纳入研究资料.用随机效应模型进行Meta分析,用标准化均数差(SMD)及其95%CI测量效果.检查可能的异质性来源,并针对研究质量和发表偏倚进行敏感性分析.为便于讨论,将SMD转换为百分率.结果对包含3 855例研究对象的42个试验进行系统评价,结果显示,旋转振动型电动牙刷去除菌斑和减低牙龈炎的效果在短期内明显优于手动牙刷,并在3个月以上的研究中显示降低了牙龈炎指数.在1~3个月的研究中,菌斑SMD为-0.43 [95%CI (-0.72, 0.14)],牙龈炎SMD为-0.62 [95%CI (-0.90, 0.34)],Quigley Hein菌斑指数降低11%,Loe and Silness龈炎指数降低6%.在3个月以上的研究中,菌斑指数SMD为-1.29 [95%CI (-2.67, 0.08)], 龈炎指数为-0.51 [95%CI (-1.76, 0.25)],Ainamo Bay探诊出血指数降低17%.短期研究之间有异质性,敏感性分析显示当选择高质量的研究时结果是肯定的,没有证据表明有发表偏倚.采取其他设计的电动牙刷并不比手动牙刷更优.对成本、可靠性和不良作用的报道不一致,已报道的不良作用都是局限的、暂时的.结论旋转振动型电动牙刷去除牙菌斑、减少牙龈炎的效果优于手动牙刷.遵守方法学指南和更标准化的设计有益于将来的研究和Meta分析.Robinson PG Deacon SA Deery C Heanue M Walmsley AD Worthington HV Glenny AM Shaw WC 陈娥 史宗道 2005中国循证医学杂志2005,5,11:8
2Combined carriership of TLR9 -1237C and CD14 -260T alleles enhances the risk of developing chronic relapsing pouchitis显示文摘AIM: To investigate the single nucleotide polymorphisms (SNPs) in genes involved in bacterial recognition and the susceptibility to pouchitis or pouchitis severity.METHODS: Analyses of CD14 -260C>T, CARD15/NOD2 3020insC, Toll-like receptor (TLR)4 +896A>G,TLR9 -1237T>C, TLR9+ 2848G>A, and IRAKM +22148G>A SNPs were performed in 157 ileal-pouch anal anastomosis (IPAA) patients (79 patients who did not develop pouchitis, 43 infrequent pouchitis patients,35 chronic relapsing pouchitis patients) and 224 Italian Caucasian healthy controls.RESULTS: No significant differences were found in SNP frequencies between controls and IPAA patients.However, a significant difference in carriership frequency of the TLR9-1237C allele was found between the infrequent pouchitis and chronic relapsing pouchitis groups [P = 0.028, odd's ratio (OR) = 3.2, 95%CI = 1.2-8.6].This allele uniquely represented a 4-locus TLR9 haplotype comprising both studied TLR9 SNPs in Caucasians.Carrier trait analysis revealed an enhanced combined carriership of the alleles TLR9 -1237C and CD14 -260T in the chronic relapsing pouchitis and infrequent pouchitis group (P = 0.018, OR = 4.1, 95%CI = 1.4 -12.3).CONCLUSION: There is no evidence that the SNPs predispose to the need for IPAA surgery. The significant increase of the combined carriership of the CD14 -260T and TLR9 -1237C alleles in the chronic relapsing pouchitis group suggests that these markers identify a subgroup of IPAA patients with a risk of developing chronic or refractory pouchitis.KM Lammers S Ouburg SA Morré JBA Crusius P Gionchetti F Rizzello C Morselli E Caramelli R Conte G Poggioli M Campieri AS Pea 2005World Journal of Gastroenterology2005,11,46:7
3Relationship between Th17 immune response and cancer显示文摘Cancer is the second leading cause of death worldwide and epidemiological projections predict growing cancer mortality rates in the next decades.Cancer has a close relationship with the immune system and,although Th17 cells are known to play roles in the immune response against microorganisms and in autoimmunity,studies have emphasized their roles in cancer pathogenesis.The Th17 immune response profile is involved in several types of cancer including urogenital,respiratory,gastrointestinal,and skin cancers.This type of immune response exerts pro and antitumor functions through several mechanisms,depending on the context of each tumor,including the protumor angiogenesis and exhaustion of T cells and the antitumor recruitment of T cells and neutrophils to the tumor microenvironment.Among other factors,the paradoxical behavior of Th17 cells in this setting has been attributed to its plasticity potential,which makes possible their conversion into other types of T cells such as Th17/Treg and Th17/Th1 cells.Interleukin(IL)-17 stands out among Th17-related cytokines since it modulates pathways and interacts with other cell profiles in the tumor microenvironment,which allow Th17 cells to prevail in tumors.Moreover,the IL-17 is able to mediate pro and antitumor processes that influence the development and progression of various cancers,being associated with variable clinical outcomes.The understanding of the relationship between the Th17 immune response and cancer as well as the singularities of carcinogenic processes in each type of tumor is crucial for the identification of new therapeutic targets.Hanna Santos Marques Breno Bittencourt de Brito Filipe Antônio França da Silva Maria Luísa Cordeiro Santos Júlio César Braga de Souza Thiago Macêdo Lopes Correia Luana Weber Lopes Nayara Silva de Macêdo Neres Rafael Santos Dantas Miranda Dórea Anna Carolina Saúde Dantas Lorena Lôbo Brito Morbeck Iasmin Souza Lima Amanda Alves de Almeida Maiara Raulina de Jesus Dias Fabrício Freire de Melo 2021World Journal of Clinical Oncology2021,12,10:5
4Sex-specific effects of Eugenia punicifolia extract on gastric ulcer healing in rats显示文摘AIM To evaluate the sex-specific effects of a hydroalcoholic extract from Eugenia punicifolia(HEEP) leaves on gastric ulcer healing.METHODS In this rat study involving males, intact(cycling) females, and ovariectomized females, gastric ulcers were induced using acetic acid. A vehicle, lansoprazole, or HEEP was administered for 14 d after ulcer induction. Body weight was monitored throughout the treatment period. At the end of treatment, the rats were euthanized and the following in vivo and in vitro investigations were performed: macroscopic examination of the lesion area and organ weights, biochemical analysis, zymography, and evaluation of protein expression levels. Additionally, the concentration-dependent effect of HEEP was evaluated in terms of subacute toxicity and cytotoxicity.RESULTS Compared to the vehicle, HEEP demonstrated a great healing capacity by substantially reducing the ulcerative lesion area in males(52.44%), intact females(85.22%), and ovariectomized females(65.47%), confirming that HEEP accelerates the healing of acetic acidinduced gastric lesions and suggesting that this effect is modulated by female sex hormones. The antiulcer effect of HEEP was mediated by prostaglandin E2 only in male rats. Overall, the beneficial effect of HEEP was the highest in intact females. Notably, HEEP promoted the expression of vascular endothelial growth factor(intact vs ovariectomized females) and decreased the expression of Caspase-8 and Bcl-2(intact female vs male or ovariectomized female). Additionally, HEEP enhanced fibroblast proliferation and migration into a wounded area in vitro, confirming its healing effect. Finally, no sign of subacute toxicity or cytotoxicity of HEEP was observed.CONCLUSION In gastric ulcers, HEEP-induced healing(modulated by female sex hormones; in males, mediated by prostaglandin) involves extracellular matrix remodeling, with gastric mucosa cell proliferation and migration.Larissa Lucena Périco Vinícius Peixoto Rodrigues Rie Ohara Gabriela Bueno Vania Vasti Alfieri Nunes Raquel Cássia dos Santos Ana Carolina Lima Camargo Luis Antuio Justulin Joior Sérgio Faloni de Andrade Viviane Miranda Bispo Steimbach Luísa Mota da Silva Lúcia Regina Machado da Rocha Wagner Vilegas Catarina dos Santos Clélia Akiko Hiruma-Lima 2018World Journal of Gastroenterology2018,24,38:3
