The process of diagnosis and nursing of a case with human granulocytic anaplasmosis who was confirmed by etiological diagnosis and molecular biology analysis was analyzed.The matters needing attention in nursing and nosocomial infection control were discussed and analyzed.To avoid misdiagnosis and mistreatment,cross infection,reduce pain and economic burden of the patients,to provide references for future diagnosis and treatment of human granulocytic anaplasmosis.

Objective To explore the factors and correlation between working pressure and psychological health and its influence of nurses.Methods A cross-sectional study design was applied.Totals of 270 nurses in a three level of first-class comprehensive hospital were selected as the research object,using the General Health Questionnaire (GHQ-12) and stress response scale to evaluate nurses' mental health level,working pressure and their influence factors and relationship.Results Among 270 nurses,69 had poor health status,with a rate of 25.50％.There were significant differences in GHQ-12 scores of different ages,gender,department,title,education and marital status (P ＜ 0.05).There was a positive correlation of working pressure and psychological health of medical staff.The more pressure the nurses suffered,the poorer psychological health status was detected.Conclusions The mental health of nurses was at an unfavorable high detection rate,and the adverse psychological health level was higher than that of the general population.The nurses of professional technology college,primary title,age less than 30 years old,and unmarried nurses were more serious.The mental health of nurses is highly related to the working pressure.

Objective To quantitatively evaluate the quality and accuracy of three-dimensional (3D) data acquired by using two kinds of structure intra-oral scanner to scan the typical teeth crown preparations.Methods Eight typical teeth crown preparations model were scanned 3 times with two kinds of structured light intra-oral scanner(A,B),as test group.A high precision model scanner were used to scan the model as true value group.The data above the cervical margin was extracted.The indexes of quality including non-manifold edges,the self-intersections,highly-creased edges,spikes,small components,small tunnels,small holes and the anount of triangles were measured with the tool of mesh doctor in Geomagic studio 2012.The scanned data of test group were aligned to the data of true value group.3D deviations of the test group compared with true value group were measured for each scanned point,each preparation and each group.Independent-samples Mann-Whitney U test was applied to analyze 3D deviations for each scanned point of A and B group.Correlation analysis was applied to index values and 3D deviation values.Results The total number of spikes in A group was 96,and that in B group and true value group were 5 and 0 respectively.Trueness:A group 8.0 (8.3) μm,B group 9.5 (11.5) μm(P＞0.05).Correlation analysis of the number of spikes with data precision of A group was r=0.46.Conclusions In the study,the qulity of the scanner B is better than scanner A,the difference of accuracy is not statistically significant.There is correlation between quality and data precision of the data scanned with scanner A.
