ObjectiveTo investigate the correlation between serum levels ofthyroglobulin antibody (TGAb),thyroid peroxidase antibody (TPOAb) and hypothyroidism incidence in Graves disease after 131Ⅰ therapy.MethodsThree hundred and twenty-five patients with Graves disease whose TGAb and TPOAb were negative before treatment were selected.Serum levels of FT3,FT4,TSH,TGAb and TPOAb were measured at the 3rd,6th,12th and 18th month after treatment respectively.All cases were divided into positive group and negative group according to the serum levels of TGAb and TPOAb at the 18th month after 131Ⅰ treatment.The hypothyroidism incidences of two groups were compared.ResultsThere were 271 cases in negative group and 54 cases in positive group.The hypothyroidism incidence was 7.4％(24/325),and the incidence of negative group was 3.0％ (8/271),while the incidence of positive group was 29.6％ (16/54).There was significant difference between two groups(P ＜ 0.05).ConclusionsHypothyroidism incidence of Graves disease after 131Ⅰ therapy has obvious correlation with the serum levels of TGAb and TPOAb.Dynamic observation of the serum levels of TGAb and TPOAb in Graves disease after 131Ⅰ therapy has important significance for clinical guiding and prognosis judgement.

Objective: In acute pancreatitis, traditional treatment insists fasting on purpose to avoid activation of proteolytic enzymes and pancreatic enzyme secretion. The aim of our study was to evaluate the efficacy and feasibility of early oral feeding as compared to traditional fasting in patients with mild acute pancreatitis.Methods: Seventy-two patients were randomized to the two treatment groups, fasting or early oral feeding. The inclusion criteria were pancreas amylase≥3times above normal, onset of abdominal pain within 48h, acute physiological and chronic health evaluation-II score<8 and C-reactive protein(CRP)<150 mg/L. Measures were amylase, systemic inflammatory response, length of hospital stay. Results: The groups were comparable with respect to age, sex, etiology, APACHE II, time from onset of pain and amylase at admission. No significant differences were seen between the groups concerning levels of amylase, CRP, leukocytes, abdominal pain or number of gastrointestinal symptoms. The length of hospital stay time was significantly shorter in the oral feeding group (13 vs. 17 days; P<0.05).Conclusion: Early oral feeding would not exacerbate disease process. The differences between treatment groups for amylase or systemic inflammatory response were not obvious. In mild acute pancreatitis, early oral feeding was feasible and safe and may accelerate recovery.

ObjectiveTo observe the effect of application of health education model on patients un-dergoing extracorpereal shock wave lithotripsy of urinary calculi. MethodsWe randomly divided 278 patients undergoing extracorporeal shock wave lithotripsy of urinary calculi into the experimental group(136 cases) and the control group(142 cases).The experimental group received health education according to the model of health education, while the control group adopted routine health education. The treatment effect of lithotripsy after 1 week,2 weeks and 1 month was evaluated. ResultsAfter health education,the cure rate at I week after lithotripsy was 50.7%, which was higher than that of the control group,28.2%, the cure rates at 2 weeks and 1 month were 58.2% and 86.0%, which were better than those of the control group, 49.0% and 70.4%. ConclusionsApplication of health education model can improve the treatment effect of extracorporeal shock wave lithotripsy of urinary calculi and alleviate pain of patients as soon as possible.

The vacuolated effect of Helicobacter (H. pylori) and its relationship to vacuolated cytotoxin antigen (VacA) were investigated by the method of cytotoxic test and SDS-pobyacrylamide gel electrophoresis (SDS-PAGE). Of the 62 clinical isolates, the broth culture filter (BCF) of 43 strains caused the Vero cell intracytoplasmically vacuolated. H. pylori strains were divided into H. pylori (Toxin+) group with vacuolated effect and H. pylori (Toxin-) group without vacuolated effect. The analysis of the BCF of H. pylori (Toxin+) and that of H. pylori (Toxin-) was studied by SDS-PAGE and Scan reader. A kind of protein with 87 ku molecular weight was recognized in the BCF of 30.23% (13/43) H. pylori (Toxin+) strains but in none of that of H. pylori (Toxin-) strains, the difference was statistically significant (P < 0.05). There was a significant and concordant relationship between OD of the protein band with 87 ku molecular weight and titer of vacuolated activity of H. pylori (Toxin+) (r = 0.67 and P < 0.05 by linear regression analysis). H. pylori strains were divided into H. pylori (Toxin+) group with vacuolated effect and H. pylori (Toxin-) group without vacuolated effect. The vacuolated effect of H. pylori (Toxin+) was caused by the protein with 87 ku molecular weight (VacA).

Objective To explore the effects of estrogen on oxidative stress of the lung tissue induced by acute paraquat (PQ) poisoning. Methods Thirty-two male adult New Zealand rabbits were randomly divided into model group and estrogen intervention group, 16 rabbits in each group. The model of lung injury induced by PQ poisoning was reproduced by feeding 16 mg/kg of 20% PQ through gastric tube. The rabbits in estrogen intervention group received intravenous infusion of 5 mg/kg estrogen after PQ challenge for 7 days, and the rabbits in model group received an equal volume of normal saline. Three rabbits in each group were sacrificed at 1, 2 and 3 days respectively after exposure. The lung tissue was harvested, the levels of reactive oxygen species (ROS) was determined by 2',7'-dichlorofluorescin diacetate (DCFH-DA), malondialdehyde (MDA) was determined by thiobarbituric acid (TBA), the mRNA expression of manganese-containing superoxide dismutase (MnSOD) was determined by reverse transcription-polymerase chain reaction (RT-PCR), and adenosine triphosphatase (ATP) content in mitochondrion was determined by enzyme linked immunosorbent assay (ELISA). The pathological changes in lung were observed under light microscopy using hematoxylin and eosin (HE) staining, and the lung injury was evaluated with lung injury score. Results The contents of ROS and MDA in lung within 3 days after PQ poisoning were gradually increased, and MnSOD mRNA expression and ATP content were gradually decreased. Estrogen intervention could significantly reduce the production of ROS and MDA after PQ poisoning [3-day ROS (fluorescence intensity): 161.05±30.04 vs. 188.30±31.80, 3-day MDA (mmol/L): 98.71±0.92 vs. 122.12±1.24], up-regulate MnSOD mRNA expression (integral A value: 3.05±0.90 vs. 1.22±0.24), and increase ATP content in mitochondrion (ng/L: 3.75±0.92 vs. 2.28±0.29) with statistically significant differences (all P < 0.01). In lung tissue after PQ poisoning, congestion, edema, focal pulmonary consolidation, pulmonary interstitial and alveolar space were infiltrated by a large number of neutrophil, alveolar interval were thickened obviously and the above phenomenon were most serious at 3 days after poisoning as shown under optical microscope. Estrogen intervention could significantly improve lung injury as compared with that of model group, and the lung injury score at 3 days was significantly lower than that of model group (11.8±0.7 vs. 13.5±1.0, P < 0.01). Conclusions The oxidative stress indicators in the lung tissue after PQ poisoning were obviously abnormal, the pathological damage was serious with time dependence. The administration of estrogen can reduce acute lung injury after PQ poisoning by reducing the oxidative stress.

Objective:To investigate the clinical value of ankle-brachial index (ABI) in evaluating vascular cognitive dysfunction (VCI) in the elderly.Methods:According to the mini mental state examination (MMSE) and Montreal cognitive assessment (MoCA), 200 elderly inpatients from May 2016 to February 2018 in our hospital were selected. MoCA scale was used to evaluate the cognitive function of the patients. The patients were divided into cognitive dysfunction group ( n=110) and cognitive normal group ( n=90). The clinical data of the two groups were analyzed and compared. The correlation between ABI and MMSE, MOCA and clinical indicators was observed. The receiver operating characteristic (ROC) curve of ABI value to the predictive value of VCI in the elderly was drawn. Results:⑴ There was no significant difference between the two groups in terms of gender, the first fasting blood glucose value in hospital and the situation of diabetes, hypertension and hyperlipidemia ( P>0.05); there was significant difference in age, low-density lipoprotein cholesterol (LDL-C) level, history of small cerebral vessels and ABI between the two groups ( P<0.05). ⑵ Logistic regression analysis showed that ABI was the related factor of VCI in the elderly ( P<0.01). ⑶ Pearson correlation analysis showed that MMSE score was positively correlated with ABI ( r=0.887, P<0.01), MOCA score was positively correlated with ABI ( r=0.843, P<0.01). ⑷ The area under ROC curve of ABI prediction value for VCI in the elderly was (0.965±0.01) [95% CI (0.945, 0.985), P<0.01]. When ABI ≤0.9, the sensitivity and specificity were 88.2%, 91.1% respectively; the accuracy and the yordan index were 89.5% and 0.793. Conclusions:⑴ ABI is an influencing factor of VCI in the elderly and is positively correlated with the severity of cognitive impairment in patients. ⑵ ABI has a high predictive value for VCI of the elderly, and ABI≤0.9 can be used as an early warning factor for VCI of the elderly.
