The 13th five-year plan pointed out clearly that it is necessary to implement food safety strategy , and form a manage-ment system for strict and efficient social co-governance of food safety .The paper introduced the practice and the results of food safety co-governance in Yunnan province , and provided some proposals with the purpose to help the development of food safety co -governance work in the other areas .

We found that medicine property and efficacy are closely linked with the shape and nature of the position of Chinese material medical through Collecting and analyzing the related articles, such as Root-based Chinese material medical has downside effect, Skin-based Chinese material medical has skin curative efficacy, Rattan-based Chinese material medical can live blood links contact us, Seed-based Chinese material medical can be used to multiply for life and so on. At last, the paper can provide a reference for the theoretical study of Chinese herbal medicine and the discovery of new drug source.

Food and drug supervision is a specialized job. However, the present supervisors coming from various departments have differences in supervision concepts, professional background, knowledge structure and work experience, which shows large gap with the requirements of supervision work. Therefore, it is urgent to strengthen the classified training for the improvement of quality construction and specialization. The article provided the curriculum system, teaching explanation and ideas about the classified training for all supervisors in the whole system, which may be beneficial to the training of food and drug supervisors.

After the structural reform in the food and drug supervision system, the knowledge structure and the professional re-quirements of the supervisors is unmatched, which hinder the fulfillment of regulatory responsibilities and the performance of adminis-trative efficacy. Effective ways for team building are actively explored throughout the country. The paper introduced the adult corre-spondence education of the supervisors in Zhejiang Ningbo food and drug supervision system to provide a good example for training work throughout the country and some useful suggestions for the quality improvement of the supervision team.

Objective:To investigate CT classification of diffuse idiopathic skeletal hyperostosis (DISH), and to analyze the correlation between the position of ossification in the anterolateral spine and the sagittal configuration of the spine.Methods:The medical records of 109 patients (70 male and 39 female) who underwent whole spine computerized tomography (CT) from October 2018 to October 2020 were retrospectively analyzed. The average age was 68.4±6.9 years old, ranging from 60 to 88 years old. High resolution CT volume rendering technique images were used to assess the degree of anterolateral spinal ossification in each vertebral space, and a CT grading system was established. Sagittal parameters such as thoracic kyphosis (TK), lumbar lordosis(LL), cervical lordosis (CL), sacral slope (SS), and thoracolumbar junction angle (TLJ) of the patients were measured. The sagittal morphology of the spine was divided into four types using the modified Abelin-Genevois (AG) sagittal classification. In AG type 1 patients, the kyphotic vertex was located in the middle of the thoracic spine (T 4-T 11). In AG type 2 patients, there was no significant kyphotic vertex. In AG type 3 patients, the kyphotic vertex was located in the thoracolumbar segment (T 12-L 2). In AG type 4 patients, the kyphotic vertex was located in the upper thoracic segment (T 1-T 3). Inter-observer and intra-observer reliability were calculated by intra-group correlation coefficient ( ICC). Statistical analysis was conducted to investigate the correlation between different AG types and ossification location and severity. Results:The new DISH grading system classifies the severity of anterolateral spinal ossification in each intervertebral space into grades 0 to 3 with an intra-observer ICC value of 0.871 and inter-observer ICC value of 0.874. Combined with Resnick's DISH diagnostic criteria, 97 patients (89.0%) in this study had four consecutive intervertebral spaces with ossification grade 1 or above. For these patients, in T 4-T 11, the standardized ossification grade of AG type 1 was 1.24±0.69, greater than that of AG type 2 (0.84±0.71) and AG type 3 (1.00±0.70), and the differences were statistically significant ( F=23.101, P<0.001). In T 12-L 2, the standardized ossification grade of AG type 3 was 1.44±0.87, which was higher than AG type 1 (1.06±0.84) and AG type 2 (0.72±0.63), the differences were statistically significant ( F=14.008, P<0.001). In this study, no patients with kyphosis apex in the cervicothoracic region (AG type4) were found. In T 1-T 3, there was no statistical difference between the three groups ( F=0.303, P=0.738); in the whole thoracic and lumbar spine (T 1-L 5), there was statistically significant difference in the total ossification grade ( F=14.374, P<0.001), there was no statistical difference between AG type 1 and AG type 3 ( P=0.254), both of which were higher than AG type 2 ( P<0.001). Conclusion:The new DISH ossification grading system proposed in this study has high credibility, which can be used in DISH's study. This study confirmed that the region where the apex of kyphosis is located is prone to anterolateral ossification of the spine.
