As one of the first resident standardized training bases, department of ophthalmology of Shanghai Ruijin Hospital participated in this reform process from 2010. Relevant rules and regulations (training management system , training scheme implementation system and evaluation system ) were strictly obeyed. When new problems emerged, under the guidance of department in charge, a series of regimens were formulated and improved gradually by Ophthalmology Professional Committee of Shanghai Resident Standardized Training Department. Based on reviewing and summarizing the work in the last 3 years, some thoughts and suggestions on the resident standardized training in future were put forward ,in-cluding how to better solve the“heavily used, lightly cultured” problem, the“disregarding medical ethics establishment”problem, the“disregarding assessment of teachers”problem and the“disregard-ing obtaining employment”problem.

OBJECTIVETo assess the economic implications of an annual vaccination strategy against influenza among people who were on a social-health program.
METHODSA retrospective cohort study was conducted. 1900 persons who had received the influenza vaccine were served as vaccine group, while 1049 persons who did not receive the vaccine were served as controls. Cluster random sampling method was used. Both of these two groups came from Donfang Company in which there were 12,109 employers in total and all of them joined the social health insurance program. The survey was carried out when the influenza vaccine was given one year ago.
RESULTSThe rates of vaccine group and control group for respiratory system diseases and cardiovascular diseases who were hospitalized, were 0.51%, 2.47% and 1.64%, 5.62% which showed 68.90% and 56.05% decrease, when compared with the control group. The crude inpatient rate among vaccinees and control group after receiving the vaccination for three and four month were 0.62%, 0.80% and 0.28%, 1.00% respectively. The inpatient rate of oldest-age group decreased by 53.59%, compared with control group. The cost-benefit ratio generated by the use of influenza vaccine in reducing the hospitalization rate was 6.48:1 for Social Health Insurants in Xi'an city.
CONCLUSIONThe Strategy to vaccinate the social-health-insured residents on influenza in Xi'an city had gained better economic benefits in reducing the hospitalization rate of respiratory system diseases and cardiovascular diseases for mild and old-aged persons.

Tendinopathies are chronic diseases of an unknown etiology and associated with inflammation. Mesenchymal stem cells (MSCs) have emerged as a viable therapeutic option to combat the pathological progression of tendinopathies, not only because of their potential for multidirectional differentiation and self-renewal, but also their excellent immunomodulatory properties. The immunomodulatory effects of MSCs are increasingly being recognized as playing a crucial role in the treatment of tendinopathies, with MSCs being pivotal in regulating the inflammatory microenvironment by modulating the immune response, ultimately contributing to improved tissue repair. This review will discuss the current knowledge regarding the application of MSCs in tendinopathy treatments through the modulation of the immune response.

TLR2 activity plays an important role in the pathogenesis of autoimmune diseases, tumor carcinogenesis and cardio-cerebrovascular diseases. To establish a TLR2 receptor-based cell screening model, NF-kappaB promoter-driven luciferase reporter plasmids were transfected into human embryonic kidney cells (HEK293) stably expressing human TLR2 and co-receptors CD14, TLR1 and TLR6. Single clones were then isolated and characterized. Using this screening system, a human TLR2-binding peptide C8 was obtained from the Ph.D.-7 Phage Display Peptide Library through biopanning and rapid analysis of selective interactive ligands (BRASIL). The binding characteristic of C8 with human TLR2 was evaluated by ELISA, flow cytometry and immunofluorescence. The NF-kappaB luciferase activity assay showed that C8 could activate the TLR2/TLR1 signaling pathway and induce the production of cytokines TNF-alpha and IL-6. In conclusion, the TLR2 receptor-based cell screening system is successfully established and a new TLR2-binding peptide is identified by using this system.
