Effect of classroom-based physical activity on teaching quality of systemic lupus erythematosus for medical undergraduates.

OBJECTIVE: To explore the influence of classroom-based physical activity (CB-PA) on the teaching quality of systemic lupus erythematosus (SLE) for medical undergraduates. METHODS: Students from 8 classes participating in the clinical medicine program of the affiliated hospital of Zunyi Medical University were divided into two groups. Four classes received regular teaching on the SLE chapter as the control group, and the other four received CB-PA intervention as the experimental group. After class, the basic ability (diagnostics and pharmacology scores in sophomore year) and teaching quality scores were collected and compared using a questionnaire. The performance of the 2 groups to the SLE review questions was compared. RESULTS: The scores of learning interest, the degree of satisfaction with the courses, and the level of mastering the teaching contents in the experimental group were significantly higher than those in the control group. The evaluation of the teacher's teaching level increased considerably. The experimental group's performance was also better than the control group's (the assessment performance was adjusted with the basic ability). CONCLUSION: CB-PA in teaching SLE improves students' interest in learning, teaching satisfaction, and mastery of knowledge and may ultimately enhance their assessment results.

Characteristics of ß-glucosidase from oranges during maturation and its relationship with changes in bound volatile compounds.

BACKGROUND: The hydrolysis of glycosidically bound volatile compounds can release potential aromas in oranges during maturation. ß-Glucosidase is the key enzyme that influences the hydrolysis of bound volatiles. In this study the changes in ß-glucosidase and bound volatile compounds in Jincheng oranges during maturation were investigated. The relationship between ß-glucosidase activity and bound volatiles was analyzed. RESULTS: The optimal temperature and pH of ß-glucosidase from Jincheng oranges were 40 °C and 5-6 respectively. Its Km and Vmax values were 0.61 mmol L(-1) and 0.009 U mg(-1) respectively. The activity of ß-glucosidase was strongly inhibited by Zn(2+), Fe(2+), Cu(2+), Ag(+), Hg(2+) and Fe(3+). ß-Glucosidase activity in pulp increased gradually during maturation, while that in peel first increased and then decreased in November. In total, 12 and 14 bound volatiles were found in pulp and peel respectively of this orange during maturation. CONCLUSION: The concentration of bound volatiles in pulp and peel decreased with the rise in ß-glucosidase activity in pulp and peel during maturation. This indicated that bound volatiles in Jincheng oranges were released during maturation owing to the increase in ß-glucosidase.

Effect of RARC-ERAS nursing program on clinical outcomes in patients undergoing RARC surgery: a retrospective, propensity matching study.

Currently, there is no specific perioperative nursing standard for RARC based on the ERAS concept. This retrospective study investigates to analyze the effect of RARC-ERAS nursing program on VTE and other clinical outcomes in patients undergoing RARC surgery. This retrospective study included 216 patients undergoing RARC surgery From January 1, 2022 to December 30, 2023, and propensity score adjustment analysis was applied. The study compares a control group receiving traditional nursing and an observation group receiving RARC-ERAS nursing program. Perioperative variables and other postoperative complications were retrieved from the hospital medical records. After propensity score matching, there were no significant differences in the demographic and clinical characteristics between the two groups (p > 0.05). The ERAS group exhibited aa significantly higher rate of postoperative unobstructed venous blood flow in the lower extremities by color Doppler ultrasound as compared to the control group (94.6% VS 80.4%, p = 0.042). Before anesthesia induction, lower preoperative anxiety and surgical information needs scores were observed in the ERAS group than in the control group (p < 0.05). Compared to the control group, the ERAS group demonstrated a shorter surgical duration, a lower incidence of perioperative hypothermia, less time needed for getting out of bed, anal exhaust, and for defecation after returning to the ward (p < 0.05). RARC-ERAS nursing program significantly increased the rate of postoperative unobstructed venous blood flow in the lower extremities by color doppler ultrasound, lower preoperative anxiety and intraoperative hypothermia in patients undergoing RARC. This nursing approach presents a valuable strategy for enhancing patient outcomes and merits further exploration in clinical practice.Trial registration:ChiCTR2400081118; http://www.chictr.org.cn , Principal investigator: Mang-mang He, Date of registration: Feb 22, 2024.

Social Security Satisfaction and People's Subjective Wellbeing in China: The Serial Mediation Effect of Social Fairness and Social Trust.

Objective: To test the relationship between social security satisfaction, social fairness, social trust, and people's subjective wellbeing (SWB) in China and the serial mediation effect in this study. Methods: We utilized the data (N = 7,978) from Chinese Social Survey (CSS) in 2017 and 2019, involving 31 provinces across the country. There were 5,398 samples in 2017CSS and 2,580 samples in 2019CSS selected by the research objectives. There were 4,269 women and 3,709 men with the average age of participants being 43 (SD = 14.41). Results: The results showed that the actual status of social security satisfaction, social fairness and trust, and SWB were greater than the theoretical status overall. Social security satisfaction [ß = 0.454, p < 0.001, 95% CI = (0.377, 0.423)], social fairness [ß = 0.065, p < 0.001, 95% CI = (-0.039, 0.124)], and social trust [ß = 0.108, p < 0.001, 95% CI = (0.237, 0.397)] positively influenced people's SWB, respectively. Social fairness had a positive effect on social trust (ß = 0.298, p < 0.001). Social fairness and social trust partly mediated the relationship between social security satisfaction and SWB, respectively. Social security satisfaction indirectly influenced SWB through the serial effect of social fairness and social trust. The total effect of SWB explained is 47% in the serial mediation model. Conclusion: Satisfactory social security is likely to cause a high level of people's SWB, social fairness, and social trust. It is beneficial to form a virtuous circle in society. Allowing people to obtain satisfactory social security is conducive to social equity, promoting social trust, and improving people's SWB.

Comparison of complications in one-stage bilateral total knee arthroplasty with and without drainage.

PURPOSE: The aim of this meta-analysis was to compare the complication rates of one-stage bilateral total knee arthroplasty (TKA) with and without drainage in order to identify whether there was no clinical significance and the value of drainage. METHODS: Randomized controlled trials (RCTs) based on bilateral TKA with and without drainage were identified via a search of PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Wanfang databases, and Google Scholar, which were published up to May 2014. Methodological quality was assessed by the Physiotherapy Evidence Database scale. After data extraction, we compared the outcomes using fixed-effects or random-effects models depending on the heterogeneity. RESULTS: Three RCTs involving 125 one-stage bilateral TKA patients with an average follow-up of 14 months met the predetermined inclusion criteria. There were 56 total complications in TKA without drainage and 17 with drainage. Except for less erythema and ecchymosis around the wound in the drainage group, there were no statistical differences in wound healing, wound infection, swelling, and deep vein thrombosis in one-stage bilateral TKA with and without drainage. CONCLUSION: The current evidences confirm that both drainage and non-drainage have similar clinical value in one-stage bilateral TKA. However, the conclusion should be used with caution due to the limitations of the current study.
