Objective To assess the teaching effect of "paper type test report" teaching mode in medical laboratory specialty undergraduate class. Methods In the teaching of "Clinical Immunology Examination" and "Clinical Thera-peutic Drug Monitoring Technology", the medical laboratory specialty undergraduate class of Grade 2009 were divided into test group(n=28) and control group(n=27)at random,"paper type test report"and traditional teaching modes were applied respectively. The teaching effects were evaluated by experiment examination result, practice result, graduation thesis and class theory achievement, etc. Results Graduation thesis scores of experimental group were significantly bet-ter than that of the control group (P<0.05). In the teaching of"the Clinical Therapeutic Drug Monitoring Technology", the experimental results, the experimental results, the theory exam overall rating scores were better than control group, and the differences were statistically significant (P<0.05). Conclusion Teaching model of "paper type test re-port"plays a positive role in improving of students' writing ability and consolidating of theory knowledge ,etc.

OBJECTIVETo investigate natural foci of tsutsugamushi disease whose incidence has increased in the Nan Peng Lie Islands in China, an area where this disease has not been previously recorded.

METHODSWe recorded the natural foci and isolated Orientia tsutsugamushi (O. tsutsugamushi) organism. We also studied prevention measures.

RESULTSThese islands had the natural foci of a south subtropical zone. The main host and vector were Rattus norvegicus and Leptotrombidium deliens (L. deliens), respectively. The seasonal quantity trends of Rattus norvegicus and Leptotrombidium deliens were consistent with the incidence of human infection. Thirty-five strains of O. tsutsugamushi were isolated from Rattus norvegicus and L. deliense. The identification of 7 strains showed that most strains were Karp. Seroepidemiology showed a high prevalence of antibody against O. tsatsugamushi among local people. After prevention measures were used, the incidence was decreased.

CONCLUSIONThis was the first successful confirmation that the Nan Peng Lie Islands were natural foci of tsutsugamushi disease.
