Objective: To explore and study the effect of individualized and standardized vestibular rehabilitation strategy in peripheral vertigo. Methods: 120 patients with peripheral vertigo in Shaanxi Provincial People's Hospital were analyzed. The 120 patients can be randomly divided into training group and control group, with 60 patients in each group. The treatment methods used in the control group included Hemorheology treatment, ion channel blocking treatment, dehydration treatment, antioxidant treatment, anti-virus treatment, etc. after treatment, no rehabilitation training measures were taken. On the basis of the treatment method of the control group, the training group carried out rehabilitation training according to the actual condition of the patients. The recurrence and improvement of vertigo symptoms of the two groups were compared, and the UCLA vertigo score and Berg Balance Scale score were analyzed. Results: after vestibular rehabilitation, the UCLA vertigo score of the training group was significantly lower than that of the control group (P < 0.05); After 4 weeks of vestibular rehabilitation training in the training group, the vertigo symptoms of the patients were significantly relieved. Compared with the control group, the difference was statistically significant (P < 0.05); Compared the BBS scores of the two groups, the training group was higher than the control group, the difference was statistically significant (P < 0.05); There were 7 cases of recurrence in the training group and 7 cases in the control group during the follow-up period. The difference was statistically significant (P < 0.05). Conclusion: individualized and standardized vestibular rehabilitation strategy for patients with peripheral vertigo can effectively reduce the course of disease, improve the cure efficiency, have significant therapeutic effect, and can be widely promoted and applied.

Coronavirus disease 2019(Covid-19) has made people around the world suffer. And there are many researchers make efforts on deep learning methods based on CT imgaes, but the limitation of  this work is the lackage of the dataset, which is not easy to obtain. In this study, we try to use data augmentation to compensate this weakness. In the first part, we use traditional DenseNet-169, and the result shows that data augmentation can help improve the calculating speed and  the accuracy. In the second part, we combine Self-trans and DenseNet-169, and the result shows that when doing data augmentation, many model performance metrics have been improved. In the third part, we use UNet++, which reaches accuracy of 0.8645. Apart from this, we think GAN and CNN may also make difference.

Preventive Medicine Research, Vol.11, No.1, 2022; 40 Views, 6 PDF Downloads

P reschool is the key period of children's visual function development, which is called the "critical period of visual development plasticity". Any abnormal stimulus during this period can have an adverse impact on children's vision. Ametropia is the main cause of poor vision in preschool children. There are many reasons for ametropia. This paper reviews the influencing factors of ametropia in preschool children in recent years, which are classified into three aspects: demographic factors, physiological factors, and lifestyle factors.

With the development of sports in various countries, more and more people participate in sports, and the rate of sports injuries to the oral and maxillofacial system also increases, especially the dental injuries caused by boxing are more common. At the same time, with the improvement of modern production, people's basic needs have been continuously met, and more and more people have begun to pay attention to their physical health and appearance characteristics. Among them, dental plastic correction and restoration have received great attention. In addition, with the application of nanotechnology in various fields in recent years, scholars at home and abroad have also tried or have continued to introduce nanomaterials into oral clinics, in order to improve and develop the application of oral materials, so that the oral clinic can be continuously improved and developed. Therefore, this paper reviews the current situation of sports injury of the oral and maxillofacial system, the mechanical analysis of tooth injury, the current situation of tooth restoration and the application of nanotechnology in the field of oral implantation.

Analysis and Development of Nurses in China Nursing Homes in the Context of Aging and Epidemics

by Dandan Zheng, Heyu Wu, Mohammad Ismail Hajary Sagor, Yuqi Cao

Preventive Medicine Research, Vol.11, No.1, 2022; 46 Views, 6 PDF Downloads

Aim:   E xamines the factors influencing the shortage of nurses in nursing homes in China in the context of global aging and Corona Virus Disease 2019( COVID-19).  Methods:  literature review . Results:  China's geriatric nursing profession is still at a low stage of development, and there are great difficulties in the demand for and training of nursing home nurses in China.  Conclusions: This paper argues that the causes of the nursing home nurse shortage in China are multifaceted and that there is no single global or local measure. Inefficient planning and use of existing nursing resources globally, global demographic conditions under the new coronavirus, and poor recruitment or insufficient supply of new staff. The facts suggest that the nursing home shortage has reached a tipping point. Given the nursing home workforce shortage and unemployment, hopefully these conditions will inspire others in the industry.
