Aspirin is one of the most important non-steroidal anti-inflammatory drugs,could inhibit cyclooxygenase.It has the antipyretic-analgesic,anti-inflammatory and anti-platelet effects,and has been widely used in preventing heart cerebrovascular disease and rheumatic autoimmune disease.Neovascularization is a self-healing mechanism.However,it also plays the role of the destroyer in cancer and eye diseases at the same time.The pathology of aspirin in the generation of neovascularization,is still in the stage of a fierce debate.On one hand,aspirin has a certain inhibitory effect to the vascular endothelial growth factor (VEGF),which is the strongest factor in neovascularization.On the other hand,aspirin also has the strongest inhibitory effect to endostatin,which is a kind of anti-neovascularization factor.That may lead to the producing of VEGF.Moreover,aspirin may destroy the blood retinal barrier (BRB),which can also cause the formation of retinal neovascularization in a way.Meanwhile,we analyzed the role of aspirin in diseases which can form the neovascular.In the future study,the relationship between aspirin and neovascularization of eye will be further studied.We must measure the pros and cons in the prevention and control of neovascularization when using aspirin.

Objective: To evaluate the outcomes and prognostic factors of myelodysplasia syndrome (MDS) patients who received allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: 165 cases of MDS who underwent allo-HSCT from Jan. 2010 to Mar. 2018 were analyzed retrospectively, focusing on the overall survival (OS) , disease free survival (DFS) , relapse, non-relapse mortality (NRM) and their related risk factors. Results: Of all the 165 cases, 105 were male and 60 were female. The 3-year OS and DFS rate were 72.5% (95%CI 64.9%-80.1%) and 67.4% (95%CI 59.17%-75.63%) , respectively. The 3-year cumulative incidence of relapse and NRM were 12.11% (95%CI 7.03%-18.65%) and 20.44% (95%CI 14.15%-27.56%) , respectively. HCT-comorbidity index (P=0.042, HR=2.094, 95%CI 1.026-4.274) was identified as independent risk factor for OS by the multivariate analysis. Intensive chemotherapy before HSCT or hypomethylation agents treatment had no effects on OS[ (67.0±7.5) %vs (57.7±10.9) %, χ²=0.025, P=0.874]. Conclusions allo-HSCT is a promising means for MDS, and NRM is the major cause of treatment failure. MDS with refractory anemia with excess blasts and secondary acute myeloid leukemia patients may not benefit from intensive chemotherapy or hypomethylation agents treatment before HSCT.

Strain-resource engineering is often considered as an important infrastructure of microbiology related research and industry. The western developed countries took the lead in establishing the classical microbial resource utilization method, and continuously improved the preservation system, species annotation technology and global sharing mechanism, which realized the expansion and reserve of biological resources since end of the 19th century. The rich and diversified germplasm resources, standard strains and production strains not only have important economic values, but also maintain the advantages of scientific research, bioeconomy (such as antimicrobial agents, vaccines, detection reagent development and standard development, etc.) and national security. Although there has been a lot of progress in related research in recent years, compared with developed countries, there is still a big gap in related fields in China. The investment and top-level design in this area lag far behind the western developed countries, and it is not commensurate with the current level of economic and social development in my country. Drawing lessons from the practice of WFCC and WDCM (World Data Center for Microorganisms, Global microbial data Center, affiliated to WFCC), for the purpose of collecting new clinical species/strains, this paper puts forward some suggestions on the identification, preservation and upload system of isolates.

Objective The demand for medical intellectual property transformation has been increasing.However,the current patent transformation system in our country is not yet perfect.The specialization and complexity of patent value evaluation hampered the transformation.In this article,we argued and analyzed the method of value evaluation before the transformation of medical patent in order to promote the transformation of medical patent.Methods Through the analysis and comparison of classic patent valuation models,the advantages and disadvantages of the three types of cost method,market method and income method are summarized,also introduced the methods and experience of Zhongshan Hospital affiliated to Fudan University.Results The three methods including comprehensive cost accounting,market value valuation and negotiation between the two parties to carry out the pre-transformation value evaluation,can help to obtain the transaction valuation value of the medical patent that meets the current actual situation.Conclusions The scientific and operable value evaluation method of medical patents before transformation,organized approval process and clear revenue management are vital strategies for the transformation of medical patents.

Objective As one of the important parts of medical scientific research outcomes,the significance of nursing patents is becoming more and more prominent during recent years.However,the nursing department is the blind spot of intellectual property in most hospitals.This article tried to explore strategies to eliminate harriers to the implementation of nursing intellectual property rights in order to promote nursing patents.Methods This paper conducted systematic analysis of the problems and obstacles in the implementation and transformation of nursing patents,and proposed tailored administrative plan.Results Identified obstacle factors include personal reasons of the nursing staff,heavy daily clinical work,as well as the immature patent system and patent market in China.Accordingly,our hospital adopted several corrective measurements,for instance,improving the support for the implementation of nursing patents,strengthening the cultivation and incubation of the intellectual property of nursing staff and standardizing the patent management.Conclusions These measures have effectively im proved the awareness and enthusiasm of nurses' patent knowledge.And we have obtained the ice breaking of the transformation of nursing patents in our hospital.

Objective: To investigate the vascular anatomy of the stomach, especially the right gastroepiploic artery for the reconstruc-tion of a gastric tube during esophagectomy. Methods: The vascular anatomy of the stomach was studiing in 28 embalmed human specimens provided by the Department of Anatomy, Shanghai Medical College, Fudan University, included 10 female and 18 male spec-imens. The length and diameter of gastric vessels were measured. The ratio of the length of the right gastroepiploic artery to the length of the greater curvature was calculated. Anastomosis between the left and right gastroepiploic arteries was also assessed. Re-sults: Twenty-five left gastric arteries were observed in the autopsies, with the mean diameter of 3.40 (2.10-6.40) mm. Twenty-one right gastric arteries were measured, with the mean diameter of 1.97 (0.68-3.56) mm. Twenty-six left gastroepiploic arteries were ob-served, with the mean diameter of 1.87 (0.80-2.96) mm. Twenty-eight right gastroepiploic arteries were measured, with the mean di-ameter of 2.82 (1.58-4.80) mm. The mean lengths of the 28 right gastroepiploic arteries and their greater curvatures were 216.71 (120-318) mm and 356.39 (248-487) mm, respectively. The ratio of the length of right gastroepiploic arteries and greater curvatures was 0.61 (0.45-0.82). The anastomosis between the left and right gastroepiploic arteries was observed in 60.7% (17/28) of the specimens. Conclusions: The length and diameter of gastric vessels were calculated. It was assumed that the right gastroepiploic artery provides an average of 61% of the blood supply for the great curvature. In addition, the anastomotic branch of the right and left gastroepiploic arteries was observed in 60.7% specimens. These anatomical data allow surgeons to estimate the blood supply and to choose an opti-mal method of gastric tube reconstruction during esophagectomy.

Objective: To analyze the impact of parental sports concept and behavior on physical activity in preschool children, so as to provide a foundation for future guidance on fostering childrens physical activity within the family context. Methods: From November to December 2020, a clustered convenience sampling method was employed to conduct surveys, and a total of 283 children were selectal from one kindergarten each in Beijing, Shenyang, and Xian. Participating children wore ActiGraph GT9X accelerometers continuously for one week to collect data on different intensity levels of physical activity. Physical Activity afterschool Questionnaire for Preschooler (P-PAQ) was utilized to assess parental sports concept and behavior. The gender differences in physical activity level and physical activity compliance rate were analyzed by using ttest, Mann-Whitney U test, and Chisquare test; and the relationship between parental exercise concepts and behaviors and physical activity of preschool children was analyzed using Spearman rank correlation analysis and multiple linear regression analysis. Results: Parental sports concept was significantly positively correlated with average daily moderatetovigorous physical activity (MVPA) and total physical activity (TPA) in children (r=0.12-0.16, P<0.05). Parental sports behavior was significantly positively correlated with childrens average daily TPA (r=0.25, P<0.05). Multiple linear regression revealed that parental sports concept was positively correlated with average daily MVPA and TPA in both boys and girls (B=0.65-0.83), while parental sports behavior only was positively correlated with boys average daily MVPA and TPA (B=0.24-0.25)(P<0.05). Conclusions Parental sports concept and behavior can impact physical activity levels in preschool children, exhibiting gender differences. Future guidance on physical activity in family upbringing should consider both parental sports concept and behavior, and pay attention to the influence of childrens gender.
