BACKGROUND:Acel ular dermal matrix has good biocompatibility and absorbability and exhibits superiority in the guided bone regeneration. OBJECTIVE:To compare the histological changes and osteogenic effects in bone defects after guided bone regeneration with acel ular dermal matrix and Bio-Gide membrane. METHODS:Mandibular second, third and fourth premolars and the first molars bilateral y were extracted from 12 beagle dogs. Three months later, four three-wal bone defect models in the mandible of each dog were made, and randomized into acel ular dermal matrix plus bone graft group (acel ular dermal matrix group), Bio-Gide plus bone graft group (Bio-Gide group), bone graft group, and blank control group (no treatment). In the former two groups, acel ular dermal matrix and Bio-Gide were used to cover the bone grafts, respectively. RESULTS AND CONCLUSION:After surgery, al the beagle dogs recovered wel . Al the groups except the control group showed dramatical improvement in histological changes and percentage of new bone area, and this improvement was more significant in the Bio-Gide and acel ular dermal matrix groups. Moreover, there was no significant difference between the Bio-Gide and acel ular dermal matrix groups. Therefore, the acel ular dermal matrix can be a candidate for bone repair instead of Bio-Gide membrane in the clinical practice.

OBJECTIVETo investigate the effects of lactulose on intestinal bacterial overgrowth (IBO), bacterial translocation (BT), intestinal transit and permeability in cirrhotic rats.
METHODSBT in all animals was assessed by bacterial culture of mesenteric lymph node (MLN), liver and spleen, and IBO was assessed by a jejunal bacterial count of the specific organism. Intestinal permeability was determined by the 24-hour urinary (99m)Tc-diethylenetriamine pentaacetatic acid ((99m)Tc-DTPA) excretion, and intestinal transit was determined by measuring the distribution of (51)Cr in the intestine.
RESULTSBT and IBO were found in 48% and 80% of the cirrhotic rats, respectively, while not in the control rats. Cirrhotic rats with IBO had significantly higher levels of intestinal endotoxin higher rates of bacterial translocation, shorter intestinal transit time and higher intestinal permeability than those without IBO. It was also found that BT were closely associated with IBO and injury of the intestinal barrier. Compared with the placebo group, lactulose-treated rats had lower rates of BT and IBO, which were closely associated with increased intestinal transit and improved intestinal permeability by lactulose.
CONCLUSIONSOur study indicate that endotoxin and bacterial translocation in cirrhotic rats may attribute to IBO and increased intestinal permeability. Lactulose that accelerates intestinal transit and improves intestinal permeability might be helpful in preventing intestinal bacterial and endotoxin translocation.

Objective:To explore the risk factors associated with a three-month prognosis in patients with aortic acute cerebral infarction.Methods:A prospective study was conducted on 191 patients with aorthropathic acute cerebral infarction included in the Department of Neurology from June 2018 to December 2019, and the patients were divided into good prognosis group (153 cases) and poor prognosis group (38 cases) according to the MRS score of the patient's 3-month prognosis, and the general data, past medical history and blood pressure variability evaluation index (BPV) between the two groups were correlated analysis. The t-test was used to compare the measurement data with normal distribution, the χ 2 test was used to compare the counting data, and the Logistic regression analysis was used to analyze the risk factors. Results:The proportion of patients with diabetes history in the poor prognosis group (20.3% (31/153)), admission NIHSS score ((3.03±2.01) points), standard deviation (SD) ((12.06±4.46) mmHg) and coefficient of variation (CV) ((8.61±3.08)%) of systolic blood pressure at 24 h were lower than those in the good prognosis group (47.4% (18/38), (5.61±3.84) points, (14.75±3.46) mmHg, (10.41±2.18)%), the differences were statistically significant (the statistical values were χ 2=11.73, t=4.01, t=3.46, t=3.38; P values were 0.001, <0.001, 0.001, and 0.001, respectively). Because 24 h systolic blood pressure SD and 24 h systolic blood pressure CV had obvious collinearity, they were respectively included in the Logistic regression model. Taking diabetes history, NIHSS score and 24 h systolic blood pressure SD into the variables, the multivariate Logistic regression results of adverse prognostic risk factors in patients with acute cerebral infarction showed that the history of diabetes mellitus ( OR=3.649, 95% CI: 1.545-8.648, P=0.003), NIHSS score ( OR=1.472, 95% CI: 1.247-1.725, P<0.001) and 24 h systolic blood pressure SD ( OR=1.201, 95% CI: 1.085-1.336, P<0.001). Taking diabetes history, NIHSS score and 24 h systolic blood pressure CV into consideration, multivariate Logistic regression results of adverse prognostic risk factors in patients with acute cerebral infarction showed that the history of diabetes mellitus ( OR=4.695, 95% CI: 1.873-11.766, P=0.001), admission NIHSS score ( OR=1.922, 95% CI: 1.513-2.441, P<0.001) and 24 h systolic blood pressure CV ( OR=1.220, 95% CI: 1.045-1.425, P=0.012). All are independent risk factors influencing the prognosis of patients. Conclusion:The effect of 24 h systolic blood pressure SD and 24 h systolic blood pressure CV on patient prognosis was more valuable in clinical prediction, and the prognosis value of controlling blood glucose levels in patients with diabetes was higher in patients with cerebral infarction.
