ABSTRACT
Objective To evaluate the efficacy of moxifloxacin-based triple therapy combined with rebamipide for Helicobacter pylori (Hp) eradication in type 2 diabetic patients.Methods Two-hundred age and sex matched type 2 diabetic patients with Hp infection and accompanied by gastrointestinal symptoms were assigned into rebamipide group (n =100) and placebo group (n =100).Both groups received moxifloxacin-based triple therapy for 10 d to eradicate Hp.Rebamipide was administrated in rebamipide group and placebo was administrated in placebo group for 30 d.All patients proceeded 14C-urea breath test (14C-UBT) hefore and 7-8 weeks after eradication therapy.The blood sugar indices,gastrointestinal symptom scores and Hp eradication rates were measured and compared.Those who had gained successful Hp eradication in both groups proceeded 14 C-UBT again 12 months after eradication therapy,and the re-infection rates of both groups were compared.Results There were no significant differences in the average fasting glucose,postprandial glucose and HbAlc levels between the rebamipide group and the placebo group before and after therapy (P ＞ 0.05),the gastrointestinal symptoms of the rebamipide group were improved more markedly than those of the placebo group after therapy (Rome Ⅲ Criteria,2.1 ± 0.9 vs.4.4 ± 0.7,P ＜ 0.01).The Hp eradication rate with both intention-to-treat (ITT) and per protocol (PP) analysis of the rebamipide group were higher than that of the placebo group [86.0％ (86/100) vs.73.0％ (73/100),P ＜ 0.05 and 92.5％ (86/93) vs.76.8％ (73/95),P ＜ 0.01].The re-infection rates with both ITT and PP analysis of those who had successful eradication in rebamipide group were lower than that in placebo group [19.8％ (17/86) vs.35.6％ (26/73),P＜0.05and20.5％ (17/83) vs.36.6％ (26/71),P＜0.05].Conclusions Moxifloxacin-based triple therapy combined with rebamipide has a more beneficial effect on Hp related symptoms,a higher Hp eradication rate and a lower Hp re-infection rate for type 2 diabetic patients.
ABSTRACT
Objective To comprehend the status of Helicobacter pylori (Hp) infection in type 2 diabetes mellitus (T2DM) patients, and study the relationship between Hp and T2DM. Methods Seven hundred and sixty-eight in-hospital T2DM patients (T2DM group, including new diagnosed 194 patients and re-diagnosed 574 patients) and 172 sex, age matched health individuals(control group ) were involved in this study. 14C-urea breath test (14C-UBT) was proceeded in both groups to determine Hp infection, and infection rates were calculated. Results Total Hp infection rate in T2DM group was significantly higher than that in control group [56.0%(430/768) vs 37.8%(65/172) ,P< 0.01], delamination analysis according to sex also showed significant differences between T2DM group and control group(P < 0.01). The rate of Hp infection in new diagnosed patients and re-diagnosed patients, female patients and male patients had no significant difference (P > 0.05 ). The rate of Hp infection in different age and sex had no significant difference (P >0.05 ). Conclusions The rate of Hp infection in T2DM patients is higher than that in non-T2DM patients.Hp infection has relationship with T2DM, and has no relationship with age, sex and course of disease.
ABSTRACT
Alc in trial group were significant better than those in control group ( P < 0. 05 ). The results indicate that type 2 diabetic patients with Hp infection should receive moxifloxacin-based triple therapy as first-line treatment.
ABSTRACT
Objective To investigate the thyroid ultrastructural pathological changes of diabetes mellitus (DM) rats as well as the intervention effects of insulin and aminoguanidine. Methods Totally 87 rats were treated with streptozotocin to establish DM animal models and divided into DM group(n=27),insulin intervention group(n=32) and aminoguanidine intervention group(n=28),25 rats were taken as normal controls. Twelve and 20 weeks after the animal model establishment, animals were sacrificed, thyroid tissue was taken and ultrastructure was observed. Results In the thyroid of DM rats, follicular epithelial cells present as applanate shape, microvilli were depleted, rough endoplasmic reticulum dilated to irregular vesicular. None pinocytotic vacuole and casual primary or secondary lysosome were seen. Follicular cavity was dilated, colloid in the cavity had higher electronic-density. Interstitial edema, capillary base lamian was thickened at different stage. Proteo-substance deposition with granulo-shape, cloud shape or homogeneity appeared. The number of thyroid parafollicular cells increased. But endocrine granule in parafollicular cells was few. When compared with DM group, the thyroid tissue injury of insulin intervention group and aminoguanidine intervention group were lessened to different degree. Conclusion The hypofunctional thyroid follicular cells, large quantity of proteo-substance deposition in the interstitium and increased parafollicular cells of DM rats may be related with hyperglycemia toxicity. Insulin and aminoguanidine treatment have some protection effects.
ABSTRACT
Objective To study variations of plasma sE-selectin and sICAM-1 level of type 2 diabetes(T2DM) patients complicated with lower limb vascular disease,and contribution of these molecules to the formation of the lower limb vascular disease. Methods Plasma sE-selectin and sICAM-1 of 51 type 2 diabetic patients and 20 age & sex matched non-diabetes people(control group) were determined with ELISA.16 T2DM patients without lower limb vascular disease and 17 age & sex matched T2DM complicated with lower limb vascular disease were selected from the patients group,as group 1 and group 2 respectively,and 17 age and sex matched non-diabetic individuals were selected from control group as group 3.sE-selectin and sICAM-1 level were contrasted among the three groups. Results Levels of FPG,2 h PG,HOMA-IR,sE-selectin and sICAM-1 of diabetic group were significantly elevated than those of the control group(P0.05).FPG and 2 h PG in group 1 and group 2 were markedly higher than that in group 3(P
