ABSTRACT
To solve the problems of insufficient airway opening, insufficient or excessive ventilation, ventilation interruption, and the rescuer's physical strength during the process of cardiopulmonary resuscitation (CPR) outside the hospital and in the hospital, and to ensure the accuracy of ventilation frequency rate and tidal volume. Zhongnan Hospital and School of Nursing, Wuhan University, jointly designed and developed a smart emergency respirator with open airway function, that has been granted National Utility Model Patent of China (ZL 2021 2 1557989.8). The device is structured of pillow, pneumatic booster pump and mask. It can be used simply by plugging the pillow under the patient's head and shoulder, turning on the power supply and wearing the mask. The smart emergency respirator can quickly and effectively open the patient's airway and give accurate ventilation with adjustable ventilation parameters. The default settings are 10 times/min in respiratory rate and 500 mL in tidal volume. The whole operation does not require the operator have professional operation ability, which can be independently applied used in any cases without oxygen source or power supply, therefore, the application scenario has no limit. The device has the advantages of small size, simple operation and low production cost, which can reduce human source, save physical strength and significantly improve the quality of CPR. The device is suitable for respiratory support in multiple scenes outside and inside the hospital, and can significantly improve the success rate of treatment.
ABSTRACT
Ventilator is an indispensable emergency medical equipment in hospitals. The global outbreak of the coronavirus disease 2019 (COVID-19) has highlighted the importance of the ventilator, which has attracted the attention and research on ventilators of all countries in the world. This article reviews the development history of the ventilator, briefly introduces the main air circuit structure and working principle of the ventilator, and then deeply analyzes the key technologies of this device. In addition, it compares some major brands of ventilators from several aspects in the market. Finally, the development trend and perspective of ventilators are presented.

In order to strictly control and prevent the risk of the coronavirus disease 2019 （COVID-19） transmission through imported cold-chain foods， Shanghai has implemented many multiple countermeasures， including “Three PointsIntermediate Sites， One Transit Cold Storage” and “Four Drive Linkage”. Shanghai cold-chain information traceability system and other operating mechanisms have been established， according to the guidance of “One Single Plan”. The multilevel， overall， traceable， life cycle and whole processand closed-loop control regulatory system， called “Shanghai mode of control” for imported cold-chain food has been basically formed， which would facilitate precise regulation and management of create an accurate management system for imported cold-chain foods.
ABSTRACT
Microfluidic technology is a scientific technology that precisely controls and manipulates fluids in micro-nano-scale space, and has become one of the research hotspots in the field of nanomedicine. It has the ability to scale the basic functions of biological and chemical laboratories, including sample preparation, reaction, separation and detection, to a few square centimeters of chip. Compared with traditional approaches, microfluidic technology is equipped with many advantages in the development of nanomedicine carriers, such as controlling quality precisely, high reproducibility, fast and effective. Herein, this paper provides the brief introduction about the microfluidic technology and its application in the preparation of nanoparticulate drug carriers, which including polymer nanoparticles, lipid nanoparticles and hybrid nanoparticles. This review will provide ideas and references in utilization of microfluidic technology accurately and reasonably and also bring some prospects for its future development and challenges.
ABSTRACT
Spatial epidemiology is a new branch of epidemiology, and is a subject that mainly analyzes the geographical distribution and changes of population health or diseases and its related impact factors. Recently, spatial epidemiology has been extensively applied in the prevention and control of parasitic diseases in China, and delightful results have been achieved. However, the research and application of theories and methods of spatial epidemiology are still needed to protect the people’s health in China.

ABSTRACT
Schistosomiasis Control and Elimination(GB 15976-2015)and Diagnostic Criteria for Schistosomiasis(WS 261-2006)are the only two national health criteria related to schistosomiasis control program implemented in P. R. China. The roles of criteria to guide and accelerate the transition from schistosomiasis control to elimination are concluded ,based on this system?atic review how the criteria led the implementation of the medium?and long?term national plan and provided the guidance when drafting the thirteen?five years national plan for schistosomiasis,and the suggestion to draft more criteria related to schistosomia?sis elimination program and strengthening the implementation of current criteria,so as to precisely guide the schistosomiasis elimination program in P. R. China.
