Objective: To understand the current situation of blood-borne occupational exposure among health care workers and evaluate the intervention effect of PDCA. Methods: Retrospective survey was adopted to investigate and analyze the blood-borne occupational exposure incidents in a hospital from January 2015 to December 2018, and to compare the intervention effects after PDCA management. Results: A total of 82 cases of occupational exposure occurred from 2015 to 2017, and only 9 cases happened after the implementation of PDCA intervention. The exposed population was mainly consisted of nurses (59 cases, 64.83%) , and mainly with low-working age (1-5 years) (56 cases, 61.54%) , and the main source of exposure was hepatitis B (34 cases, 37.36%) . In addition, after the implementation of PDCA, the vaccination rate of personnel was 77.78%, the standardized field treatment rate was 100%, the preventive drug use rate was 88.89%; The qualified rate of occupational protection assessment was higher than that before intervention, which all shows the difference was statistically significant (P<0.05) . Conclusion With the guide of PDCA management, Strengthen the training of new employees or ones with low working years as well as their awareness of protection, and standardize the relevant operational procedures, which can significantly improve the prevention of blood-borne occupational exposure and stress management of medical staff.

Objective To evaluate the efficacy of Disposcope endoscope(DE)-guided nasotrache-al intubation in patients with difficult airway by comparing with fiberoptic bronchoscope(FOB). Methods One hundred and twenty American Society of Anesthesiologists physical statusⅠ-Ⅲ patients of both se-xes, with body mass index<25 kg∕m2, aged 18-64 yr, with mouth opening<3 cm, of Mallampati classifi-cation Ⅲ or Ⅳ, undergoing maxillofacial surgery requiring nasotracheal intubation were divided into DE group(n=60)and FOB group(n=60)using a random number table.Nasotracheal intubation was per-formed under the guidance of DE or FOB after induction of anesthesia.Glottis exposure was evaluated using Cormack-Lehane grade.Epistaxis during intubation, successful intubation, time and degree of glottis expo-sure, intubation time and development of tachycardia and hypertension and requirement for assisted ventila-tion with face mask during intubation were recorded.The patients were followed up postoperatively, and the development of intubation-related complications was also recorded.Results Compared with group FOB, glottis exposure time and incubation time were significantly shortened(P<0.05), and no significant change was found in Cormack-Lehane grade, rate of successful incubation, rate of successful intubation at first attempt or intubation-related complications in group DE(P>0.05). Hypertension and tachycardia were not found and no patients required assisted ventilation with face mask during intubation in the two groups.Conclusion DE-guided nasotracheal intubation provides similar efficacy to that of FOB with shorter time and is an optimal selection for the patients with difficult airway.

OBJECTIVETo explore the difference between adolescent and adult C57BL/6J mice in response to rapid eye movement sleep (REMS) deprivation in terms of anxiety behavior and hippocampal NO level.

METHODSBoth adolescent and adult C57BL/6J mice were divided into normal control (NC) group, wide platform (WP) group, and 24-hour REMS deprivation group, each group consisting of 15 mice. REMS deprivation models were established using a small platform in water tank, and the elevated plus maze test was used to examine anxiety behavior of the mice. After behavioral tests, the mice were sacrificed to examine hippocampal NO levels using enzyme-linked immunosorbent assay, and hippocampal nNOS protein expression was detected with Western blotting.

RESULTSThe adolescent C57BL/6J mice showed no obvious differences in anxiety behaviors between the 3 groups, but NO level and nNOS expression in the hippocampus was significantly higher in REMSD group than in NC and WP groups (P<0.01). The adult mice in REMSD group, compared with those in the other two groups, exhibited significantly increased total number of arm entry (P<0.01), lowered number of open arm entry and reduced open arm time (P<0.01), increased number of close arm entry and prolonged close arm time (P<0.01 or 0.05); no obvious differences in NO level or nNOS expression in the hippocampus were found in the 3 groups of adult mice.

CONCLUSIONREMS deprivation produces different effects on anxiety-related behaviors between adolescent and adult mice possibly in relation to their different responses in terms of NO levels and nNOS expression in the hippocampus.

OBJECTIVETo study the therapeutic molecular mechanism of the warm-hot drugs treating cold syndrome.

METHODA brother and his sister with deficiency-cold syndrome were chosen and treated with appropriate Chinese formula consisted chiefly of warm-hot drugs for 45 days. Then microarray technique was applied for comparing the gene expression difference of sister who had significant effect, the data was dialed with multiple analysis method and the results were mined though gene function and pathway.

RESULT276 differential genes were obtained, which were related to metabolism and 18 pathways.

CONCLUSIONWarm-hot drugs work on the gene expression of metabolism. It may be exerting the curative action by gene network and there is distinct difference between gene expression of curative effect and syndrome.
