The idea of establishing Shanghai Academy of Medical Sciences was brought forward　in the background of great external changes.It was to meet the demand for resolving all kinds of　conflicts about researches arised from the long time operation of Medical Institutes in Shanghai.This　article mainly discusses about the necessity and plans for establishing Shanghai Academy of Medical　Sciences.

This study surveyed medical research institutions in Shanghai for the structure set, input and output, development orientation, bottleneck and other aspects. Problems were found with their relationship management, discipline arrangement, research efficacy and else.

Medical research institutions in Shanghai have been developing in at a slow pace because of problems such as out of date institution structures, unreasonable resource allocation and distribution,shortage of research resources, insufficient creativity, and unfocused effort and investment. Hence reform is the only way out. This research discussed the possible strategies for development and proposed some suggestions on the institution categorization, structure change, allocation of resource and overall arrangement.

Objective:To analyze the current situation of public health management and public health services in public hospitals at the second level and above in Anhui Province, for references for the government to formulate relevant policies.Methods:A stratified whole-group random sampling method was used to investigate the current status of public health services provided by 55 public hospitals at the second level and above in Anhui Province. The contents of the questionnaire included the establishment of public health management departments, operation and public health services. Descriptive analysis was conducted for all data, and chi-square test was used for comparison between groups.Results:Of the 55 hospitals, only one tertiary hospital had a separate public health department, while the public health management works of the other hospitals were scattered among the hospital infection department, medical affairs department, preventive health department and so on. 32 hospitals putted the public health services into their performance appraisal. Among the public health services provided by hospitals, the management of infectious disease diagnosis and treatment presented the best performance, as 55 hospitals had established relevant management systems, processes, business training, infectious disease reporting and other information systems. Mental health service presented the poorest performance, as only 36 hospitals had established relevant management systems.Conclusions:The public health management and service level of public hospitals in Anhui Province needed to be further improved. The government authorities should strengthen their top-level design and coordinate the public health department setup and performance evaluation mechanism of public hospitals from the institutional level. On the other hand, the public hospitals should constantly optimize their content of public health services, complement the weaknesses, and effectively improve the level of public health services based on respective conditions of the hospitals.

Objective To evaluate the role of C-X-C chemokine receptor type 4 ( CXCR4) in the dorsal root ganglia ( DRG) in incisional pain in rats. Methods Thirty-two male Sprague-Dawley rats, aged 7-10 weeks, weighing 250-300 g, in which intrathecal catheters were successfully implanted, were divided into 4 groups (n＝8 each) using a random number table method: sham operation group (group S), CXCR4 antagonist AMD3100 plus sham operation group (group A+S), incisional pain group (group I) and CXCR4 antagonist AMD3100 plus incisional pain group (group A+I). Rats were anesthetized with sevoflu-rane. AMD3100 20 μg (in 10 μl of normal saline) was intrathecally injected, and no incision was made 30 min later in group A+S. A 1-cm longitudinal incision was made through skin, fascia and muscle of the plantar aspect of the left hindpaw in group I. AMD3100 20 μg (in 10 μl of normal saline) was intrathecally injected, and 30 min later the model of incisional pain was established in group A+I. The mechanical paw withdrawal threshold ( MWT) and thermal paw withdrawal latency ( TWL) were measured at 24 h before surgery and 2, 4, 8, 16 and 24 h after surgery. The rats were sacrificed after the last measurement of pain threshold and the DRGs of the lumbar segment (L4-6) were removed for detecting the expression of CXCR4, phosphorylated extracellular regulated protein kinase ( p-ERK) and total ERK ( t-ERK) by Western blot. Results Compared with group S, MWT was significantly decreased and TWL was shortened at T1-5in group I and group A+I, and the expression of CXCR4 and p-ERK in DRGs was significantly up-regulated (P＜0. 05), and no significant change was found in the expression of t-ERK in group I, no significant change was found in the expression of CXCR4, p-ERK and t-ERK in group A+I, and no significant change was found in the parameters mentioned above in group A+S (P＞0. 05). Compared with group I, MWT was significantly increased and TWL was prolonged at T1-5, the expression of CXCR4 and p-ERK in DRGs was down-regulated (P＜0. 05), and no significant change was found in the expression of t-ERK in group A+I (P＞0. 05). Conclusion CXCR4 in DRGs is involved in incisional pain, and the mechanism may be re-lated to activating ERK1∕2 signaling pathway in rats.

Objective:To sort out medical device related policies in Anhui Province,to analyze the distribution of content in each policy text to provide reference for policy optimization in the later stage.Methods:The official websites of the People's Government of Anhui Province and the Anhui Provincial Drug Administration were searched by using the keywords of"medical devices","medical device enterprises",and"medical consumables"to search for medical device related policy documents released from January 2011 to December 2022.The 21 medical device-related policy documents retrieved shall be coded using the content analysis method in the sequence of"policy code-chapter number-unit number-sentence number".A two-dimensional analytical framework of"Basic Policy Instruments-Involved Subjects"was constructed to quantitatively analyze the medical device policy text from the two dimensions of policy instruments-involved subjects.Results:A total of 338 items were codes,including 107 supply-based policy tools(accounting for 31.66%),40 demand-based policy tools(accounting for 11.83%),and 191 environmental policy tools(accounting for 56.51%).The 338 codes involved entities including 202 government departments(accounting for 59.76%),62 operating enterprises(accounting for 18.34%),59 production enterprises(accounting for 17.46%),9 medical institutions(accounting for 2.66%),and 6 industry associations(accounting for 1.78%).Conclusion:The medical device policy in Anhui Province is mainly based on environmental policy tools,and demand-based policy tools are rarely used.The rationality of the distribution of internal items and participating entities in policy tools needs to be improved.There are certain differences in the interaction between each entity and policy tools.Therefore,it is necessary to strengthen the balance of policy tool use,increase the participation of multiple entities,and optimize the synergy between entities and policy tools.
