Objective To investigate the preventive effect of clinical nursing pathway of health education on partum urinary retention.Methods Two hundred and forty primiparas hospitalized in our hospital from September 2012 to February 2013 were randomized equally into the observation group and the control group.The former received health education by clinical nursing pathway and the control group conventional health education.The two groups were compared in terms of incidence of postpartum urinary retention.Results The incidences of postpartum urinary retention in the observation group and the control one were 3.33% and 11.67%,respectively.The difference in the incidence between the groups were statistically significant(P<0.05).Conclusion The clinical nursing pathway of health education may effectively prevent the occurrence of postpartum urinary retention.

Objective To investigate the reliability and validity of a novel hand-held dynamometer, OE-210, for muscles strength of low-er extremities. Methods From March 1st to August 30th, 2016, 38 young adults were tested the muscle strength of quadriceps and ham-strings with OE-210 dynamometer by 2 rators, and were retested by one of the raters three days later. The isokinetic test was also conducted on all the subjects one day afterwards. The intraclass correlation coefficient (ICC) of OE-210 test results and the Pearson's correlation coeffi-cient between results of OE-210 and isokinetic test were calculated. Results The ICC of test-retest were 0.718 to 0.924, and the ICC of in-ter-rater were 0.784 to 0.870. The correlation between muscle performance measured with 2 tools were significant (P<0.001), that was light to medium on quadriceps (r=0.270-0.413), and strong on hamstrings (r=0.582-0.668). Conclusion OE-210 dynamometer was reliable for muscle strength measurement on quadriceps and hamstrings, and the conditions for valid application need further research.

Objective To investigate a simple,minimally invasive and effective operative method for the facial rejuvenation in the upper eyelid and midface region.Methods Blepharoplasty was combined with suspending orbicularis oculi muscle flap and fixing it on the periosteum underneath the eyebrow through eyebrow incision.Meanwhile,for midface rejuvenation,inferior palpebral margin incision was performed and prezygomatic interspace was separated completely under the orbicularis oculi muscle.The under-eye puffiness and tear trough deformity were corrected through releasing orbital fat,reposition and fastening orbital septum,and transposition of orbicularis oculi muscle flap.And the deep sulci nasolabialis and cheek anetoderma were relieved by dual lifting of malar fat pad and orbicularis oculi muscle flap.Follow-up was taken at the 1 week,3 months,6 months,1 year,2years and 3 years after operation.Each case was evaluated with postoperative effect,reprocessing time and postoperative complications and underwent photography.Results From Feb.2010 to Oct.2014,190 patients (9 male,181 female,an average age of 49.03 ± 5.67 years) underwent this operation.Obvious improvement on the upper eyelid and midface region was achieved in all the patients after operation without serious or irreversible complication.Conclusions Combining eyebrow and inferior palpebral margin incision,through suspending the malar fat pad and orbicularis oculi muscle flap at the same time,as a simple,minimally invasive and reliable method,can strengthen the effect of the facial rejuvenation in the upper eyelid and midface region markedly.

Objective:To investigate the teaching activity based on an online radiological teaching case library that integrates various teaching models including problem-based learning (PBL), case-based learning (CBL), flipped classroom, and microclass, as well as its application effect in standardized residency training in department of radiology.Methods:A total of 65 physicians who completed standardized residency training in Department of Radiology, Sun Yat-sen Memorial Hospital of Sun Yat-sen University, from 2016 to 2022 were enrolled as subjects and were divided into control group with 32 physicians and experimental group with 33 physicians. The physicians in the control group received traditional teaching, and those in the experimental group received blended teaching with PBL, CBL, flipped classroom, and microclass based on a teaching case library. The two groups were compared in terms of the test scores of clinical thinking and decision making at the end of the course and their assessment and feedback for the teaching method. SPSS 22.0 was used to perform the t-test and the chi-square test. Results:For the assessment of clinical thinking and decision making, compared with the control group, the experimental group had significantly higher score of objective essay questions (49.83±1.27 vs. 48.74±1.64, P<0.05), score of subjective essay questions (39.57±1.75 vs. 36.02±1.81, P<0.05), and total score (89.40±1.54 vs. 84.76±1.93, P<0.05). The experimental group had significantly better assessment and feedback for the teaching method than the control group ( P<0.05). Conclusions:For physicians participating in standardized residency training, the blended teaching model based on teaching case library that integrates PBL, CBL, flipped classroom, and microclass can effectively improve the test scores of clinical thinking and decision making, stimulate their learning initiative and participation enthusiasm in medical imaging, and enhance their comprehensive ability for clinical diagnosis.
