Objective To compare the ischemia-modified albumin(IMA)level between T2DM and AMI,and to discuss the possible mechanism and pathology process.Methods According to the decrease of power of albumin binding cobalt along with the increase of ischemia-modified albumin,the automated continuous detection of free cobalt in reactive system were conducted using the 480nm wavelength and the results were reported as absorbance unit(ABSU)and coloration rate of free cobalt.Results There were significant differences in serum free cobalt between the control and groups of acute coronary syndrome(ACS)and type 2 diabetes and between ACS and type 2 diabetes(P

Objective:To investigate the present situation of humanity education for medical students and to provide theoretical evidence for establishing appropriate interventions. Methods:This paper surveyed and analyzed the present situation of humanity education for medical students in a medical university using questionnaires. Re-sults:18. 7% of medical students entirely remembered the specific content of Hippocratic Oath, 7. 3% of medical students had never heard about the concepts such as humanistic quality, 31. 7% of medical students had never bor-rowed humanity and social science books from the school library, 79. 3% of medical students thought it necessary to strengthen humanity education. Some results showed that there were significant differences in different grades and specialties. Conclusion:It is necessary to further strengthen humanity education for medical students, improve the quality of humanity curriculum, and make a fusion of humanity education and the medical professional education. At the meantime, the humanity courses should be increased and the educational program should be diversified.

Objective:To study the effects of enhanced breastfeeding management on the neurodevelopmental outcomes of preterm infants in neonatal intensive care unit (NICU).Methods:From January to December 2020, preterm infants with gestational age (GA) ≥32 weeks admitted to NICU of our hospital were randomly assigned into the enhance group and the control group. Breast-feeding education using WeChat and routinely playing recorded mother's sound to the infants were carried out in the enhance group, while conventional management was carried out in the control group. Breastfeeding status was followed up regularly in both groups. Mental development index (MDI) and psychomotor development index (PDI) at 6-month of corrected GA were measured using Infant Intelligence Development Scale.Results:A total of 109 cases were included in the enhance group and 118 cases in the control group. The breast-feeding rates in the enhance group were significantly higher than the control group at discharge, 3-month and 6-month of corrected GA [88.1% (96/109) vs. 61.0% (72/118), 90.8% (99/109) vs. 67.8% (80/118), 88.1% (96/109) vs. 61.9% (73/118)] ( P<0.05). MDI and PDI at 6-month of corrected GA in the enhance group were significantly higher than the control group [(106.2±10.7) vs. (101.9±11.4), (103.4±13.7) vs. (99.5±11.6)] ( P<0.05). Conclusions:Enhanced breast-feeding management is helpful improving the breast-feeding rate of preterm infants in NICU and beneficial to the neurodevelopment of preterm infants.

Objective To verify the reliability of novel 3D classification of intertrochanteric fractures by comparing the consistency between conventional and novel classifications.Methods Included for the present study were the preoperative X-ray and CT images of 189 patients with intertrochanteric fracture who had been hospitalized at Department of Orthopaedics,Beijing Chao Yang Hospital,Capital Medical University from 1 January,2017 to 1 January,2019.The patients' intertrochanteric fractures were classified by 6 orthopedic surgeons independently using Evans classification,Jensen classification,AO classification and novel 3D classification,respectively.One month later,the original images of the 189 patients were renumbered and classified again in the same way.The Kappa values between observers and within observers were calculated for the classifications of intertrochanteric fractures based on X-ray and CT images.Results In Evans classification,Jensen classification,AO classification and novel 3D classification,the interobserver Kappa values of X-ray films were 0.54 ± 0.03,0.53 ± 0.03,0.45 ± 0.03 and 0.63 ± 0.02,respectively,and the interobserver Kappa values of the CT images were 0.49 ± 0.03,0.49 ± 0.03,0.44 ± 0.04 and 0.63 ± 0.03.The intraobserver Kappa values of the X-ray films were 0.53 ± 0.02,0.54 ± 0.03,0.44 ±0.04 and 0.65 ± 0.02,respectively,and the intraobserver Kappa values of the CT images were 0.52 ± 0.03,0.52 ±0.03,0.41 ±0.02 and 0.64 ±0.03.In the novel classification based on X-ray and CT images,the interobserver and intraobserver Kappa values were both significantly higher than those in Evans,Jensen and AO classifications (P ＜ 0.05).Conclusion The novel 3D classification of intertrochanteric fractures is more reliable than the conventional ones.
