Objective:To investigate the improvement in antibiotics use in our hospital by comparing the prophylactic application of antibiotics in type I incision before and after antimicrobial drug special rectification. Methods:The medical records of 100 hospital-ized patients undergoing I incision respectively from May to December in 2011 (before the rectification), from May to December in 2012 ( during the rectification) and from May to December in 2013 ( after the rectification) were withdrawn randomly. The prophylactic application of antibiotics was statistically and comparatively analyzed. Results: After the antimicrobial drug special rectification, the prophylactic application rate of antibiotics was reduced from 100% to 28%, and in 7 kinds of operations stressed by the National Health and Family Planning Commission ( inguinal hernia repair, thyroid disease, breast disease, arthroscopy, carotid endarterectomy, skull tumor resection and endovascular interventional diagnosis) , the prophylactic use rate of antimicrobial drugs was reduced to 11%. The variety choice of antibiotics in type I incision was more reasonable. The irrationality rate of medication time and course was de-creased obviously, and the accuracy of dosage and usage was improved significantly. The combination of antibiotics was also notably decreased. Conclusion:The antimicrobial drug special rectification is effective, which can significantly improve the prophylactic appli-cation rationality of antibiotics for type I incision in our hospital.

With the increasingly strengthening of economic globalization and higher education internationalization,medical imageology as an important intersecting science in life sciences has more and more international communion and cooperation.In China many hospitals and medical colleges require large quantities of medical imageology professionals,and it is very necessary and important to develop the bilingual education in medical imageology,though a series of problems appear in the process.

The developing situation of "big image" makes the medical imaging become an increasingly huge and complicated system.It offers higher request to the medical imaging teaching.The internship of last term is always influenced by attending the graduate student's entrance examination and looking for job,the effect of teaching can't be assured,and it especially important to do well in field trip,thus it can reduce or avoid the phenomenon of "practice after graduate".

Objective: To investigate the association between the family relationship of college students in Shanghai and the psychological stress response under the COVID-19 epidemic. Methods: Totally 904 college students from universities in Shanghai were investigated with questionnaire of FACESII-CV and IES-R. Results: The score of family relationship intimacy was(61.32±6.29), the score of family relationship adaptability was(43.30±5.83), the score of psychological stress was(30.77±7.33), the score of internal dimension，avoidance, high alertness were(11.63±2.53)(11.69±2.64)(7.45±2.33). About 77.5%(701) and 17.3%(156) of college students showed mild and moderate stress reactions. Three dimensional scores of psychological stress response and two dimensional scores of family relationship differed significantly by age, grade, family income and parental education(P<0.01). Moreover, family relationship intimacy and adaptability scores showed negative associations with intrusive symptoms, avoidance symptoms, and high alert symptom dimension scores(P<0.05). Conclusion College students showed mild psychological stress under the COVID 19 epidemic with intrusion and avoidance symptoms as the most common. The intimacy and adaptability of family relationships are negatively associated with psychological stress response of college students under the epidemic. High-quality family relationships can reduce the psychological impact and adverse effects of the new crown epidemic on college students.

Objective:To explore the effect of nursing interventions based on individual and family self-management theory (IFSMT) on postoperative rehabilitation of patients undergoing percutaneous transforaminal endoscopic surgery.Methods:A total of 835 patients who underwent percutaneous transforaminal endoscopic surgery in Shanxi Provincial People's Hospital from January 2018 to January 2020 were selected as research objects by the convenient sampling method. According to the random envelope method, patients were divided into the control group ( n=417) and the observation group ( n=418) according to the approximate 1∶1 standard. The control group was given routine nursing intervention, while the observation group was given nursing intervention based on IFSMT on the basis of the control group. The differences in self-management ability, postoperative recovery time, lumbar functional recovery, pain score and postoperative complication rate before and after intervention were compared between the two groups. Results:After intervention, the scores of treatment management, psychological management, life management and knowledge and skill management in the observation group were higher than those before intervention and were higher than those in the control group, and the differences were statistically significant ( P<0.01). The hospitalization days, self-care time and work recovery time of observation group were shorter than those of control group, and the differences were statistically significant ( P<0.01). After intervention, the Oswestry dysfunction index and pain score in the observation group were lower than those before intervention and lower than those in the control group. The treatment score evaluated by the Japanese Orthopedic Association was higher than that before intervention and higher than that of the control group, and the differences were statistically significant ( P<0.01). The incidence of postoperative complications in observation group was lower than that in control group, and the difference was statistically significant ( P<0.05) . Conclusions:IFSMT based nursing intervention for patients undergoing percutaneous foraminal endoscopic surgery is beneficial to postoperative rehabilitation of patients, which is worthy of clinical promotion.

PURPOSE: This study is intended to investigate the effects of plants or plant-derived antioxidants on prevention of osteoporosis through the maintenance of reactive oxygen species (ROS) at a favorable level. MATERIALS AND METHODS: In this study, a novel antioxidant, namely 3,4,5-Trihydroxy-N-[4-(5-hydroxy-6-methoxy-pyrimidin-4-ylsulfamoyl)-phenyl]-benzamide (ZXHA-TC) was synthesized from gallic acid and sulfadimoxine. Its effect on osteoblast metabolism was investigated via the detection of cell proliferation, cell viability, production of ROS, and expression of osteogenic-specific genes including runt-related transcription factor 2 (RUNX2), bone sialoprotein (BSP), osteocalcin (OCN), alpha-1 type I collagen (COL1A1), and osteogenic-related proteins after treatment for 2, 4, and 6 days respectively. RESULTS: The results showed that ZXHA-TC has a stimulating effect on the proliferation and osteogenic differentiation of primary osteoblasts by promoting cell proliferation, cell viability, and the expression of genes BSP and OCN. Productions of bone matrix and mineralization were also increased by ZXHA-TC treatment as a result of up-regulation of COL1A1 and alkaline phosphatase (ALP) at the early stage and down-regulation of both genes subsequently. A range of 6.25x10(-3) microg/mL to 6.25x10(-1) microg/mL is the recommended dose for ZXHA-TC, within which 6.25x10(-2) microg/mL showed the best performance. CONCLUSION: This study may hold promise for the development of a novel agent for the treatment of osteoporosis.
