Spodoptera frugiperda, an important migratory insect in the world, has been a serious threat to maize production in China since its invasion. Although the chemical prevention was e任icient and urgent, it was also easy to cause the drug resistance and environmental safety of Spodoptera frugiperda. In order to reduce the usage of chemical pesticides, the indoor toxicity determination of different pesticides to Spodoptera frugiperda larvae was carried out, and the field efficacy trials of the four kinds of biological pesticides on Spodoptera frugiperda on maize were studied and evaluated. The results showed that: the efficacy of the four kinds of biological pesticides, including 20 billion spores • g_1 Beauveria bassiana oil-based suspension concentrate, 30 billion spores • g_1 Beauveria bassiana wettable powder, 8 000 IU • uL_1 Bacillus thuringiensis suspension agent and 1% Sophora flavescens • azadirachtin emulsion, was 7& 29% --85.84%, 60.70% --82.81%,. 73.06% -- 81. 89% and 73. 18% --83. 19%, respectively, after 7 days of application. The four kinds of biological pesticides had no adverse effect on the maize growth, no phytotoxicity, no growth-promoting effect, and no obvious adverse effect on the beneficial organisms in maize fields. This study showed that the four kinds of biological pesticides> including 20 billion spores • g_1 Beauveria bassiana oilbased suspension concentrate, 30 billion spores • g_1 Beauveria bassiana wettable powder, 8 000 IU • uL_1 Bacillus thuringiensis suspension agent and 1% Sophora flavescens • azadirachtin emulsion, could effectively control the damage of Spodoptera frugiperda after 7 days of application, and could be widely used in the maize fields with low density population.

Objective To define the accuracy of robotic assistance in deep brain stimulation surgery and to compare the results in the literature. Methods The data of 10 patients with dyskinesia treated by deep brain electrical stimulation assisted by mechanical arm (Huake precision) were reviewed retrospectively. Postoperative CT review confirmed the comparison between electrode position coordinates, approach angle and preoperative designed target coordinates and approach angle data. The accuracy was analyzed between the intended location of the target and actual location of leads. Results There is no statistically significance between the actual and intended entry angle. Right side X,Y and left side Y coordinates of actual distal contacts were significantly different between the actual and intended entry angle (P < 0.05-0.01). Others had no statistically significance. The euclidian 3D distances between the intended and actual location of the contact were (1.81 ±0.81) mm. Mean radial error was (1.41 ±0.82) mm. Conclusion Robot-assisted technology for stereotactic surgery is safe and accurate. [ABSTRACT FROM AUTHOR]

According to the characteristics of diatomite in a project in Namibia, such as high moisture content, high compressibility, low density and other characteristics, we analyzed and compared the characteristics of parameters obtained by the SPT and the CPTU in situ test and indoor soil test, carried out on-site preloading test, and analyzed settlement and pore pressure change law under stage load, which indicated that deep diatomite with larger SPT number still be settling, the coefficient obtained from preloading test is similar to the coefficient obtained from CPTU in situ test. Finally, the compression modulus and consolidation coefficient obtained from SPT or CPTU in situ test is adopted to calculate consolidation settlement. The study can provide reference for similar projects. [ABSTRACT FROM AUTHOR]

ObjectiveTo compare subthalamic nucleus (STN) deep brain stimulation (DBS) with globus pallidus interna(GPi) DBS for tremor suppression in Parkinsons disease (PD). MethodsBetween January 2016 and December 2017, 56 PD patients received bilateral DBS in Xuanwu Hospital. Participants were divided into two groups based on different targets. STN group included 20 male and 10 female, mean age was (59.3 ± 10.7) years old. GPi group included 19 male and 7 female, mean age was (61.3 ± 7.2) years old. Patients were assessed before operation and in the following up three months using the Unified PD Rating Scale. ResultsDBS ON versus OFF were compared at med on and med off state and were found a significant difference before and after operation except GPi group med on state. However,the difference between the STN and GPi was not significant. ConclusionsDBS is effective in reducing tremor in PD patients regardless of stimulation target. However, the degree of tremor suppression in STN DBS versus GPi DBS is equivalent. [ABSTRACT FROM AUTHOR]

The sand compaction pile (SCP) method can be adopted to improve soft marine clay, which composes the composite foundation. The method can reducing settlement, accelerating consolidation, increasing bearing capacity and increasing slope stability, which makes it possible to build the underwater immersed tunnel on soft marine clay. Based on the immersed tunnel foundation of the Hongkong-Zhuhai-Macao Bridge, we introduced the basic principle, design method, and treatment effect of immersed tunnel on soft marine clay by the sand compaction pile method. The replacement ratio of SCP composite foundation in transition section of immersed tunnel is 40% to 70%. With the monitoring and instrumentation during preloading stage and tunnel building stage, most of the total settlement are within an order of 8 cm and differential settlement are within 0.11%. It realizes rigid-flexible coordination between immersed tunnel and foundation and smooth transition of settlement from immersed tunnel to artificial island. [ABSTRACT FROM AUTHOR]

Objective To explore the efficacy and safety of stereotactic selective thalamotomy for the treatment of writer's cramp( WC). Methods 47 patients(32 men,15 women,age 15-64 years, mean 28.9 years) with medically intractable task-specific focal dystonia of the hand underwent Vim thalamotomy.The stereotactic target was chosen at ventralis intermedius nucleus. The mean duration of the symptom ranged from 2 to 21 years ( mean 5 .5 years). Results All patients showed immediate postoperative disappearance of dystonic symptoms, and the effect was sustained during the follow-up period (6-36 months, mean 23 months), except in 3 cases. One patient showed partial recurrence of the symptom and underwent second thalamotomy 6 months after the initial surgery with satisfactory results. The score on WC rating scale decreased significantly (P<0.001) after Vim thalamotomy.There were no permanent operative complications.There was no mortality or permanent morbidity. Conclusion Although a longer follow-up is needed, stereotactic Vim thalamotomy is a useful and safe therapeutic option for writer's cramp. [ABSTRACT FROM AUTHOR]
