Objective To explore different approaches in administrating polyethylene glycol (PEG) solution in bowel preparation.Methods From January 2015 to June 2015, 218 patients eligible for this study were randomly divided into three groups (group A, 2 L PEG solutions 4 hours before colonoscopy; group B, 2 L PEG solutions 6 hours before colonoscopy; group C, 1 L PEG the night before and 1 L at least 4 hours before colonoscopy). The quality of bowel preparation was assessed on the basis of the Boston bowel preparation scale. A questionnaire was also completed to assess the subjective feelings of the preparation, including the overall satisfaction and discomfort with drug preparation, the feeling of abdominal distension, abdominal pain, nausea and vomiting, and the character of stool.Results In terms of intestinal cleanliness, statistical difference was shown between groups. Significant difference was found between group A and group C. However, the PDR between these three groups showed no statistical difference. No signiifcant difference was found between the three groups considering the overall satisfaction and subjective feelings of preparation.Conclusions Without affecting the subjective feelings of patients, splitting dose of PEG solution improve the quality of bowel preparation and is worthy to be recommended.

Objective:To investigate the role of LncRNA ZBED3-AS1 in osteoblast proliferation and differentiation in osteoporotic rats through regulating miR-339-5p/Notch 1.Methods:The rat models of sham operation (Sham) group and model (Model) group were established, and the bone mineral density (BMD) of rats was examined. Rat osteoblasts were isolated and the expression of ZBED3-AS1 and miR-339-5p was detected by qRT-PCR. The osteoblasts of rats in Sham group and Model group were divided into different groups and transfected. CCK8, alizarin red (AR-S) staining and alkaline phosphatase (ALP) staining were used to detect the proliferation and differentiation ability of cells in each group. The distribution of ZBED3-AS1 in cells was determined by FISH assay. Double luciferase report confirmed the relationship between ZBED3-AS1 and miR-339-5p as well as miR-339-5p and Notch 1.Western blot was used to detect the expression of Notch pathway related factors.Results:The bone mineral density of femur in Model group was significantly lower than that in Sham group ( P=0.0057) . Compared with Sham group, the expression of ZBED3-AS1 in osteoblasts of Model group was lower, while that of miR-339-5p was higher (all P<0.05) . Overexpression of ZBED3-AS1 could promote the proliferation and differentiation of osteoblasts, while knockdown of ZBED3-AS1 could inhibit the proliferation and differentiation of osteoblasts (all P<0.05) . ZBED3-AS1 could regulate miR-339-5p as ceRNA (all P<0.05) . Overexpression of miR-339-5p can inhibit the proliferation and differentiation of osteoblasts, which can be partially saved by overexpression of ZBED3-AS1. Notch 1 was confirmed as a target of miR-339-5p, at the same time, interfering with the expression of ZBED3-AS1/miR-339-5p can affect the expression of Notch-1 protein, and the regulation of ZBED3-AS1/miR-339-5p on osteoblasts may be realized through Notch pathway. Conclusion:ZBED3-AS1 can be used as ceRNA to regulate miR-339-5p, and then affect the proliferation and differentiation of osteoblasts in osteoporotic rats.

ObjectiveTo compare the feasibility of establishing the rat model of acute coronary syndrome with combined blood stasis and poison by lipopolysacharide （LPS） injection， ligation of coronary artery and different combinations of the two methods. MethodA total of 225 male SD rats were randomly divided into sham operation group， simple coronary artery ligation group， first injected LPS group ［LPS（5 mg·kg）injection 24 h before coronary artery ligation］ and follow injected LPS group ［LPS（5 mg·kg）injection 10 min after coronary artery ligation］. The indexes of each group were detected at 3， 24， 72 h after modeling， and the model was comprehensively evaluated. The general state and macroscopic evaluation indexes of traditional Chinese medicine （TCM） syndrome （tongue and pulse） of rats in each group were observed. ECG and echocardiography were used to evaluate cardiac function， and the myocardial ischemia and infarction areas were measured by Evans blue/2，3，5-triphenyltetrazolium chloride （TTC） staining. The content of creatine kinase isoenzyme （CK-MB）， lactate dehydrogenase （LDH）， creatine kinase （CK）， and troponin T （cTnT） in serum as well as interleukin-1 β （IL-1β） and IL-6 changes were determined by biochemical method or enzyme-linked immunosorbent assay （ELISA）. Hematology analyzer was adopted to determine the white blood cell （WBC） count， and the four coagulation indexes， platelet aggregation rate， hemorheology and other coagulation evaluation indexes were also detected. The myocardial tissue was observed by hematoxylin-eosin（HE）staining. ResultAfter 3 h of modeling， compared with the conditions in sham operation group， the R， G and B values of tongue of rats （P<0.01）， pulse amplitude （P<0.01）， and cardiac function in simple coronary artery ligation group were decreased， and the color of hypoglossal veins became purple（P<0.01）. The content of CK， LDH， cTnT， IL-1β and IL-6 in serum（P<0.05）， myocardial infarction area（P<0.01）， and total number of WBCs （P<0.05）were increased. Compared with simple coronary artery ligation group， first injected LPS group and follow injected LPS group had increased hypoglossal veins， decreased R value of tongue and elevated cTnT content （P<0.01）， while follow injected LPS group had reduced B value of tongue， decreased cardiac output （CO）（P<0.05）， increased IL-1β content， and thinned left ventricular anterior walls at end-systole （LVAWs）（P<0.01）. After 24 h of modeling， compared with sham operation group， simple coronary artery ligation group presented significantly decreased R， G and B values of tongue， lengthened purplish dark hypoglossal veins （P<0.01）， reduced pulse amplitude（P<0.01） and cardiac function， enlarged myocardial infarction area（P<0.01）， increased whole blood viscosity， platelet aggregation rate， fibrinogen （FIB）， shortened prothrombin time （PT） and thrombin time （TT）（P<0.01）， and elevated total number of WBCs （P<0.01）and content of CK， LDH， cTnT and IL-6 in serum（P<0.05）. Compared with the conditions in simple coronary artery ligation group， the pulse amplitude， R， G and B values of tongue （P<0.01）， and ejection fraction （EF） and fractional shortening （FS） scores （P<0.05）dropped， and hypoglossal veins were deepened and lengthened（P<0.05）， and cTnT content was increased（P<0.01）in first injected LPS group and follow injected LPS group. However， follow injected LPS group had thinned LVPWs， increased LDH content， platelet aggregation rate（P<0.05）， myocardial infarction area， and total number of WBC， level of IL-1β（P<0.05）， and shortened TT（P<0.01）. Additionally， 72 h after modeling， compared with sham operation group， simple coronary artery ligation group showed significantly reduced pulse amplitude， lowered R， G and B values of tongue， thickened and lengthened hypoglossal veins（P<0.01）， decreased cardiac function， and increased content of cTnT， FIB， whole blood viscosity（P<0.01），platelet aggregation rate， level of IL-6 and IL-1β（P<0.05）. Compared with the conditions in simple coronary artery ligation group， the hypoglossal veins of the first injected LPS group and the follow injected LPS group were more purple， and the content of cTnT was boosted（P<0.01）， whereas follow injected LPS group had decreased pulse amplitude， R， G and B values of tongue， EF and FS scores （P<0.05）， and enlarged myocardial infarction area（P<0.01）. ConclusionCompared with the other modeling methods and models at different modeling time， the established model by LPS injection 10 min after coronary artery ligation for 24 h was more consistent with the clinical characteristics of acute coronary syndrome with combined blood stasis and poison.
