Objective To investigate the correlation between preoperative anxiety and emergence agitation(EA)in children after sevoflurane anesthesia.Methods A total of 120 children who were going to receive an elective surgery were recruited in this study.The preoperative anxiety in these children was measured through the Modified Yale Preoperative Anxiety Scale(mYPAS)at the following time:during the preoperative interview(T1),waiting period in surgery waiting room(T2),after the children entered the operating room(T3)and at the beginning of sevoflurane inhalation induction(T4).The emergence agitation(EA)scores were obtained by using the Pediatric Anesthesia Emergence Delirium(PAED) Scale after the surgery.Results After adjusting for the effect of age,it was found that the anxiety scores at T1 and T2 had no significant correlation with EA,while those in T3 and T4 showed a statistically significant correlation with EA.The level of anxiety at the beginning of induction showed a strong positive correlation with EA,and the correlation coefficient was 0.708(P<0.01).Conclusion The preoperative anxiety in the operating room and at the beginning of induction of anesthesia is correlated with EA in children receiving sevoflurane anesthesia.

Low grade inflammation has recently emerged as a common underlying cause of many chronic diseases. Heart disease, type 2 diabetes, Alzheimer's disease and many types of cancer have all been associated with chronic inflammation. Diabetes is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Insulin resistance is a key component in the development of diabetes mellitus which is caused by inflammation, and throughout the whole process of diabetes. In recent years, research on traditional Chinese medicine treatment of diabetes has got lots of achievements, and makes a further analysis about insulin resistance of diabetic, while has profound significance in the treatment of diabetes in the future. Insulin resistance can be improved with Chinese herb medicine using compound, single herbal drug and its extracts. This review focuses on the pathogenesis of inflammation and insulin resistance, and the effects of Chinese herb medicine on insulin resistance in diabetes.

Forensic biology is a main subject of forensic medicine.With the rapid development of science and technology,the courses should be constantly improved.New teaching mode has come into being application of multimedia technology in theoretical lessons,case teaching,independent completion of experimental lessons,which is thanks to the constant reinforcement of teaching staff and the reform of course content and teaching methods.

The article elaborated the standard of quality control,open service management system and requirements for system construction of forensic biology laboratory,which is to share laboratory recourses and advance the healthy and sustainable development of the laboratory.

Based on the experience of experimental teaching reform of forensic biology,the article made a systematic exposition about the measures and experience of the research and practice of the reform from the following aspects: aim of the reform,priority of the reform and specific measures.By reforming experimental teaching methods,the students' interests and performance record have been significantly improved.

It is now well established that inflammation plays an important role in the development of numerous chronic metabolic diseases including insulin resistance (IR) and type 2 diabetes (T2DM). Skeletal muscle is responsible for 75% of total insulin-dependent glucose uptake; consequently, skeletal muscle IR is considered to be the primary defect of systemic IR development. Our pre- vious study has shown that rutaecarpine (Rut) can benefit blood lipid profile, mitigate inflammation, and improve kidney, liver, pan- creas pathology status of T2DM rats. However, the effects of Rut on inflammatory cytokines in the development of IR-skeletal muscle cells have not been studied. Thus, our objective was to investigate effects of Rut on inflammatory cytokines interleukiri (IL)-1, IL-6 and tumor necrosis factor (TNF)-α in insulin resistant primary skeletal muscle cells (IR-PSMC). Primary cultures of skeletal muscle cells were prepared from 5 neonate SD rats, and the primary rat skeletal muscle cells were identified by cell morphology, effect of ru- taecarpine on cell proliferation by MTT assay. IR-PSMC cells were induced by palmitic acid (PA), the glucose concentration was measured by glucose oxidase and peroxidase (GOD-POD) method. The effects of Rut on inflammatory cytokines IL-1, IL-6 and TNF-α in IR-PSMC cells were tested by enzyme-linked immunosorbent assay (ELISA) kit. The results show that the primary skeletal muscle cells from neonatal rat cultured for 2-4 days, parallel alignment regularly, and cultured for 7 days, cells fused and myotube formed. It was shown that Rut in concentration 0-180. 0 μmol x L(-1) possessed no cytotoxic effect towards cultured primary skeletal muscle cells. However, after 24 h exposure to 0.6 mmol x L(-1) PA, primary skeletal muscle cells were able to induce a state of insulin resistance. The results obtained indicated significant decrease (P < 0.05 to P < 0.001) IL-1, IL-6 and TNF-α production by cultured IR-PSMC cells when incubating 24 hours with Rut, beginning from 20 to 180.0 μmol x L(-1). IL-1, IL-6 and TNF-α in the Rut treated groups were dose-dependently decreased compared with that in the IR-PSMC control group. Our results demonstrated that the Rut promoted glucose consumption and improved insulin resistance possibly through suppression of inflammatory cytokines in the IR-PSMC cells.

With the rapid development of genetic engineering and metabolic regulation, antisense technology displays its fascination to the world as a mild regulation genetic tool. Compared with other loss-of-function research methods (e.g. gene knockout), antisense technologies have advantages such as low cost, short period, and easy operation. It has been increasingly used in bacterial metabolic regulation as a powerful genetic tool. This review briefly summarized the latest progress and problems in antisense technologies that are recently used in metabolic engineering of bacteria, and compares the advantages and disadvantages of these technologies.

Objective To evaluate the effect of clopidogrel premedication on in-hospital major adverse cardiovascular and cerebral events (MACCE) and bleeding outcomes before coronary artery bypass graft surgery (CABG). Method A total of 2021 patients who underwent CABG from July 2003 to September 2005 were divided into either clopidogrel ( n = 479) or no clopidogrel (1542) group before CABG. Patients with clopidogrel administration ( n = 479) were subdivided into < 5 d ( n = 154) ,5～7d(n = 183)and >7d(n = 142) group according to timing of clopidogrel withdrawal before surgery. In-hospital MACCE and perioperative bleeding outcomes were analyzed among groups. Results Patients who took clopidogrel before surgery had nonsignificantly rates of bleeding and in-hospital MACCE compared with those patients not administered clopidogrel. No differences were found about the incidence of total bleeding,minor bleeding,transfusions of red blood cells,fresh frozen plasma,whole blood and in-hosptial MACCE among three subgroups.The < 5 d group had higher incidence of major bleeding and more platelets transfusions than 5 ～ 7 d [47.8% vs. 31.9%,P < 0.017; (0.08 ±0.38) U vs. (0.00±0.00) U,P <0.017,respectively]and >7 d group [47.8% vs. 20.3%,P <0.017; (0.08±0.38) U vs. (0.00±0.00) U,P <0.017,respectively). However,there were no significant differences between 5 ～ 7 d and > 7 d group ( P > 0.05). Conclusions Gopidogrel administration before CABG does not increase the incidence of in-hospital MACCE events. However,the perioperative risk of bleeding will rise if the patients withhold clopidogrel less than five days before surgery.
