Malaria remains a serious public health problem in Shandong Province, China; therefore, it is important to explore the characteristics of the current malaria prevalence situation in the province. In this study, data of malaria cases reported in Shandong during 2012-2014 were analyzed, and Plasmodium species were confirmed by smear microscopy and nested-PCR. A total of 374 malaria cases were reported, 80.8% of which were reported from 6 prefectures. Of all cases, P. falciparum was dominant (81.3%), followed by P. vivax (11.8%); P. ovale and P. malariae together accounted for 6.4% of cases. Notably, for the first time since 2012, no indigenous case had been reported in Shandong Province, a situation that continued through 2014. Total 95.2% of cases were imported from Africa. The ratio of male/female was 92.5:1, and 96.8% of cases occurred in people 20-54 years of age. Farmers or laborers represented 77.5% of cases. No significant trends of monthly pattern were found in the reported cases. All patients were in good condition after treatment, except for 3 who died. These results indicate that imported malaria has increased significantly since 2012 in Shandong Province, especially for P. falciparum, and there is an emergence of species diversity.

The research combines the scientific research reality, which meets to the characteristic and environment request of all-terrain vehicles (ATV). According to the principle of component lectotype for Powertrain Coupling system of HEV, and the demands of performance parameter of ATV about power, torque and speed when ATV is under movement condition, this research is focus on the powertrain coupling system between engine electric motor and wheel which has carried on the optimized matching, the modeling simulation and the experiment. The article has determined one kind of new multipurpose design and development plan on the powertrain coupling system in electric and HEV for ATV. It focal introduces the new powertrain coupling system based on the Cycloidal Planetary gearing transmission with Few-tooth-difference (CPF), which have applied in powertrain coupling system of the multipurpose light electric and HEV for ATV. To provide the control strategy of clutches-brakes and brakes system with electromagnetic controlled in the CPF for developing controllers for motor, engine and central controller for E & HEVs ATV power distribution. The findings indicated, the powertrain coupling system designs might satisfy the performance requirement for entire vehicle in wild beach. The method and the obtained result provided basis design theory for ATV and multipurpose light electric and HEVs. The technology has applied to ATV in Ningbo Saiting Electric Bicycle Science & Technology CO., LTD, and has applied patent.
