Under the guidance of the new development paradigm, the Chinese Academy of Sciences (CAS) has started a series of pioneering international cooperation in the Belt and Road countries with scientific and technological innovation, especially along the 21st Century Maritime Silk Road. CAS advanced the practical cooperation with the research institutions of the countries to improve their research and innovation capabilities. Taking the example of high-quality development, the China-Sri Lanka Joint Center for Education and Research (CSL-CER), satisfied the Sri Lanka's demands for science and education. This paper describes the progress and significance of achieved results by promoting high-quality development, and suggests for the development of CSL-CER in the future. [ABSTRACT FROM AUTHOR]

Objective To explore the clinical features, diagnosis and treatment of Calcifying Fibrous Tumor（CFT） in the scrotum. Methods A retrospective analysis of the clinical data of a pediatric CFT in the scrotum admitted to our hospital was reviewed, and the clinical characteristics and methods of diagnosis and treatment were discussed in combination with literatures. Results The child had no symptoms. The scrotum color Doppler ultrasound and CT showed multiple calcifications in the scrotum. The tumor was excised under general anesthesia. There was no malignant component in the frozen pathological examination. The pathological diagnosis was CFT. There was no recurrence or metastasis in the follow-up period of 6 months. Conclusion The diagnosis of CFT of the scrotum relies on histopathological examination, and complete surgical resection of the mass is safe and effective. [ABSTRACT FROM AUTHOR]

A series of 2BMFJ type no-tillage planter has been proposed to serve as a feasible operation mode of “preparation of side-way anti-blocking seed bed and concurrently covered with uniform straw”. The amount of straw mulching can generally determine the effect of straw returning on soil improvement and crop growth benefit. If the amount of straw mulching is too small, there is no obvious effect on the soil moisture conservation and fertilizer cultivation. In this case, it is recommended that the straw can be returned to field in the whole amount. Nevertheless, if the straw mulching is too large, the yield of crop can decline due to “low temperature effect” and “biochemical effect” in some areas with high content of soil organic matter. As such, the proportional straw returning to the field can be used in a straw proportion regulation technology and supporting device under the operation mode of lateral straw cleaning, according to the environmental conditions in soil. The structural parameters of device can be determined using various theoretical analysis. In this study, a multi-link mechanism was designed to control the throwing trace of straw by adjusting the deflection angle of spring-tooth. Two correction coefficients of kx and ky were introduced to the model of straw throwing trace for an accurate simulation. The high speed camera system was selected to in-situ capture the throwing process of straw. The movement and distribution of straw throwing can be achieved, in order to determine the proportion of straw return to field. A cloud map was performed on a Matlab platform, thereby to quantify the distribution of straw. The deflection angle of throwing control baffle and gravity was 45°, when the proportion of straw returning to field was not less than 50%. The field experiment was carried out at the Xiangyang farm of Northeast Agricultural University from October 21 to 22, 2019, where a corn stubble field with the soil hardnessof28.1 kg/m² and soil moisture content of 21.7%. Four factors and five levels quadratic regression orthogonal rotation center combined experimental method can be applied to optimize the influence of various parameters on straw returning proportion, the structure and working parameters in a proportion regulation device. The deflection angle of spring-tooth, area of recovery port, operating speed and straw mulching amount were selected as influencing factors, where as the proportion of straw returning to field were selected as the evaluation index of performance. The test results showed that the area of recovery port and deflection angle of spring-tooth had an extremely significant impact on the test indicators (P<0.01), while the straw mulching amount and operating speed had a secondary impact (0.01

Objective To evaluate the value of three-dimensional transrectal ultrasound（3D-ERUS）and sagittal transrectal ultrasound in preoperative TN-staging and circumferential resection margin (CRM) of rectal cancer. Methods A total of 111 patients with rectal cancer were selected from our hospital. Among them, 71cases of middle and lower rectal cancer were examined by 3D-ERUS，40 cases of upper rectal cancer were examined by sagittal transrectal ultrasound. The pathological results were used to compare the accuracy of rectal cancer TN-staging and CRM using 3D-ERUS and sagittal transrectal ultrasound. Results The overall accuracy of preoperative T/N-stage of rectal cancer were 87.4%（kappa=0.819，P＜0.001）and74.8%(kappa=0.572，P＜0.001), respectively，and the accuracy of CRM was 94.6%. Conclusions The preoperative evaluation of total rectal cancer by 3D-ERUS and sagittal transrectal ultrasound has high diagnostic accuracy and consistency.Combined application can improve the diagnostic value of transrectal ultrasound in preoperative staging of total rectal cancer.
