目的观察益气化瘀解毒法对慢性萎缩性胃炎(CAG)伴异型增生(Dys)模型大鼠EGFR/MAPK信号通路的影响。方法 60只SPF级健康雄性Wistar大鼠随机分为空白组10只,造模组50只。空白组给予SPF级动物标准饮食喂养,持续至实验结束。造模组采用以120 mg/L的N-甲基-N'-硝基-N-亚硝基胍(MNNG)溶液灌胃,每只5 m L/kg,1次/d为主,配合自由饮用0.1%氨水溶液及进食含0.03%雷尼替丁的颗粒状饲料,3种因素联合建立CAG伴Dys大鼠模型。28周末造模成功后将造模组剩余的30只大鼠随机分为模型组、维酶素组、益气化瘀解毒法组(中药组),每组各10只,均给予SPF级动物标准饮食喂养,并且每天灌胃1次,维酶素组予维酶素悬浊液2 m L/kg(即维酶素0.3 g/kg),中药组予益气化瘀解毒中药3 m L/kg(含生药9 g/kg),模型组予生理盐水3m L/kg。12周后即实验第40周末处死全部大鼠。选用Western blot法对各组大鼠胃窦部黏膜组织中EGFR、ERK1/2、p-ERK1/2蛋白表达进行检测。结果模型组EGFR蛋白表达最高,其次是维酶素组、中药组、空白组;其中,模型组与空白组和中药组比较均有显著性差异(均P0.01),中药组与维酶素组比较有显著性差异(P0.05)、与空白组比较无显著性差异(P0.05)。模型组ERK1/2蛋白表达最高,其次是维酶素组、中药组、空白组;其中,模型组、维酶素组与空白组和中药组比较均有显著性差异(均P0.01),中药组与空白组比较也有显著性差异(P0.01)。模型组p-ERK1/2蛋白表达最高,其次是维酶素组、中药组、空白组;其中,模型组与空白组和中药组比较均有显著性差异(均P0.01),中药组与维酶素组有显著性差异(P0.01)、与空白组比较无显著性差异。结论益气化瘀解毒法可显著抑制EGFR的高表达及EGFR/MAPK细胞信号转导通路的异常激活,这可能是其治疗CAG伴Dys、逆转胃癌前病变(PLGC)、防治胃癌的有效作用机制之一。 相似文献

J Oral Pathol Med (2012) 41 : 500–504 Background: Atrophic glossitis (AG) is considered to be a marker of nutritional deficiency. In this study, we evaluated whether there was an intimate association of the deficiency of hemoglobin, iron, vitamin B12 or folic acid, high blood homocysteine level, and serum gastric parietal cell antibody (GPCA) positivity with AG. Methods: The blood hemoglobin, iron, vitamin B12, folic acid, and homocysteine concentrations and the serum GPCA level in 176 AG patients were measured and compared with the corresponding levels in 176 age‐ and sex‐matched healthy control subjects. Results: We found that 39 (22.2%), 47 (26.7%), 13 (7.4%), and 3 (1.7%) AG patients had deficiencies of Hb (men < 13 g/dl, women < 12 g/dl), iron (<60 μg/dl), vitamin B12 (<200 pg/ml), and folic acid (<4 ng/ml), respectively. Moreover, 38 (21.6%) AG patients had abnormally high blood homocysteine level, and 47 (26.7%) AG patients had serum GPCA positivity. AG patients had a significantly higher frequency of Hb, iron, or vitamin B12 deficiency, of abnormally elevated blood homocysteine level, or of serum GPCA positivity than healthy control subjects (all P‐values = 0.000). However, no significant difference in frequency of folic acid deficiency was found between AG patients and healthy control subjects. Conclusion: We conclude that there is a significant association of deficiency of hemoglobin, iron and vitamin B12, abnormally high blood homocysteine level, and serum GPCA positivity with AG. 相似文献

Hashimoto described four patients with goiter. The histology of the goiter was characterized by diffuse lymphocytic infiltration, fibrosis and epithelial cell destruction. Thyroglobulin antibody (TGAb) and thyroid peroxidase antibody (TPOAb) have been used to diagnose Hashimoto’s thyroiditis. Patients with positive TGAb and/or TPOAb have been assumed to have Hashimoto’s thyroiditis. Approximately 10% of those with positive TGAb and/or TPOAb have hypothyroidism. There are two types of autoimmune thyroiditis: goitrous Hashimoto’s thyroiditis and atrophic thyroiditis. The latter patients have blocking antibody (thyroid-stimulating hormone [TSH]-stimulation blocking antibody [TSBAb]). TSBAb is a TSH-receptor antibody (TRAb). TSBAb causes thyroid atrophy and hypothyroidism. TGAb and/or TPOAb do not necessarily cause hypothyroidism. Hypothyroid patients with Hashimoto’s thyroiditis usually receive life-long l-thyroxine therapy. However, spontaneous recovery from hypothyroidism has been reported. Patients who had Hashimoto’s hypothyroidism and then Graves’ hyperthyroidism (and vice versa), have also been reported. Hashimoto’s hypothyroidism and Graves’ hyperthyroidism could be the opposite spectrums of one disease. 相似文献

Reconstruction of the atrophic edentulous maxilla with free iliac crest grafts and implants: a 3-year report of a prospective clinical study 总被引:3,自引:0,他引:3
Sjöström M Sennerby L Nilson H Lundgren S 《Clinical implant dentistry and related research》2007,9(1):46-59
Purpose: The purpose of this study was to perform a longitudinal follow-up study of implant stability in grafted maxillae with the aid of clinical, radiological, and resonance frequency analysis (RFA) parameters. Materials and Methods: The atrophic edentulous maxillae in 29 patients were reconstructed with free iliac crest grafts using onlay/inlay or interpositional grafting techniques. The endpoint of the resorption pattern in the maxilla determined the grafting technique used. Endosteal implants were placed after 6 months of bone-graft healing. Implant stability was measured four times using RFA: when the implants were placed, after 6 to 8 months of healing, after 6 months and 3 years of bridge loading. Individual checkups were performed at the two later RFA registrations after removal of the supraconstructions (Procera® Implant Bridge, Nobel Biocare AB, Göteborg, Sweden). Radiological follow up of marginal bone level was performed annually. Results: Twenty-five patients remained for the follow-up period. A total of 192 implants were placed and with a survival rate of 90% at the 3-year follow up. Women and an implant position with a class 6 resorption prior to reconstruction were factors with significant increased risk for implant failure (multivariate logistic regression). Twelve of the 20 failed implants were lost before loading (early failures). The change in the marginal bone level was 0.3 ± 0.3 mm between baseline (bridge delivery) and the 3-year follow up. The implant stability quotient (ISQ) value for all implants differed significantly between abutment connection (60.2 ± 7.3) and after 6 months of bridge loading (62.5 ± 5.5) (Wilcoxon signed ranks test for paired data, p=.05) but were nonsignificant between 6 months of bridge loading and 3 years of bridge loading (61.8 ± 5.5). There was a significant difference between successful and failed implants when the ISQ values were compared for individual implants at placement (Mann-Whitney U test, p=.004). All 25 patients were provided with fixed implant bridges at the time of the 3-year follow up. Conclusion: This clinical follow up using radiological examinations and RFA measurements indicates a predictable and stable long-term result for patients with atrophic edentulous maxillae reconstructed with autogenous bone and with delayed placement of endosteal implants. The ISQ value at the time of placement can probably serve as an indicator of level of risk for implant failure. 相似文献
