Quality of Life in Chinese Youth Following Open Thyroid Surgery: A Qualitative Study.

BACKGROUND: Because of the increased incidence of thyroid cancer and good survival rates and with research into scarless techniques, it is increasingly important to understand the quality of life of thyroid cancer patients and identify areas for improvement. Therefore, it is necessary to explore the importance of neck appearance after thyroidectomy for thyroid cancer survivors in China. OBJECTIVE: The purpose of this study was to investigate the effect of scarring after open thyroid surgery on the quality of life of young patients. METHODS: A descriptive qualitative design was used. Data were collected using face-to-face semistructured interviews and analyzed using directed content analysis. RESULTS: Five men and 19 women participated in the study. The following 3 broad themes and 9 subthemes emerged, which were (1) emotional functioning, including low self-esteem due to high visibility of scars, concerns and helplessness about scarring lesions, and feelings of isolation due to lack of support; (2) social functioning, including restricted choice of employment, avoidance of socializing with others, and reduced participation in social activities; and (3) information seeking, acceptance, and living with the scar, including bargaining, seeking professional help, and use of social media. CONCLUSIONS: After open surgery for thyroid cancer, patients experience a variety of scarring features that affect their quality of life. Therefore, preoperative communication and long-term postoperative care should be emphasized in clinical practice and research. IMPLICATIONS FOR PRACTICE: Understanding the experience of carrying scars after thyroid cancer surgery helps provide adequate information, expectation management, and informed decision-making.

24-hour movement behaviours and self-rated health in Chinese adolescents: a questionnaire-based survey in Eastern China.

Objective: Although much evidence has demonstrated the benefits of adhering to the 24-hour movement guidelines, little is known about their association with self-rated health in adolescents. The objective of this study was to explore the association between adherence to the 24-hour movement guidelines (i.e., physical activity, screen time, and sleep) and self-rated health among Chinese adolescents aged 10-17 ages. Methods: A convenient sample of 12 schools and their students were recruited for this cross-sectional study. Physical activity and screen time were assessed using a questionnaire based on the Health Behaviour in School-aged Children questionnaire, while sleep duration was used measured using the Pittsburgh Sleep Scale. Ordinal logistic regression was performed to examine the association between adherence to the 24-hour movement guidelines and self-rated health. Results: Adolescents who adhered to more guidelines contained in the 24-hour movement guidelines reported better self-rated health. A dose-response association was observed, with the odds ratio (OR) for adhering to all three = 11.26, 95% CI [4.82-26.35]; OR for meeting two = 1.62, 95% CI [1.25-2.12]; OR for meeting one = 1.16, 95% CI [0.98-1.38]) indicating a higher probability of better self-rated health with increasing adherence. Regarding adherence to specific combination of 24-hour movement guidelines, positive associations were found for adhering to all three recommendations (OR = 11.95, 95% CI [5.06-28.19]), only MVPA (OR = 4.96, 95% CI [2.82-8.72]), MVPA + screen time (OR = 5.50, 95% CI [3.02-9.99]), and MVPA + sleep (OR = 4.63, 95% CI [2.52-8.51]). Conclusion: This study provides evidence supporting the association between adherence to the 24-hour movement guidelines and better self-rated health among Chinese adolescents. Sufficient physical activity may be particularly important for promoting self-rated health in this population.

Experience of verbal violence among Chinese nursing students in clinical practice: a qualitative study.

BACKGROUND: Workplace violence is prevalent in the nursing profession, and as a relatively junior link of the professional hierarchy, nursing students are not immune to it. Among these, verbal violence may have more serious consequences for the victims than physical violence, but the literature on verbal violence among nursing students in Chinese clinical settings is limited. AIMS: To explore the verbal violence experience among Chinese nursing students in clinical practice, and the strategies used by nursing students to cope with violence. DESIGN: A descriptive qualitative study. METHODS: From January 2022 to June 2022, semi-structured interviews were conducted with 21 nursing students in clinical practice by purposive snowball sampling. Nvivo12 software and inductive content analysis were used for data analysis. This paper followed the COREQ (Consolidated criteria for Reporting Qualitative Research) guidance. RESULTS: Through data analysis, three themes were defined:(1) Multiform verbal violence; (2) Hurting and impacting and (3) Struggling or Coping. The findings indicated that nursing students were subjected to multiple forms of verbal violence in clinical practice, not only from patients and caregivers, but also from peers such as clinical tutors and doctors, which not only harmed students' personal health and well-being, but may also contribute to the nursing industry's future loss of human resources. Seeking emotional support from others and forcing themselves to grow up were the most commonly used coping strategies. CONCLUSION: Nursing educators and nursing managers need to pay attention to verbal violence in the clinical environment, and actively develop the ability of nursing students to deal with uncivilized behavior. Establishing relevant courses and training such as communication, resilience, and violence prevention, establishing a stricter clinical mentor appointment system, and teaching assessment system may be strategies to help nursing students better perform clinical practice.

The challenges of returning to work for differentiated thyroid cancer survivors in china: a qualitative study.

PURPOSE: Although thyroid cancer survivors have a good prognosis and the survival rate of differentiated thyroid cancer is close to 100%, treatment and its side effects seriously affect the quality of life of patients, especially rehabilitation at work. The purpose of this study was to explore the challenges faced by differentiated thyroid cancer survivors in returning to work and maintaining employment. METHODS: A purposive sample of differentiated thyroid cancer patients who had undergone surgical treatment and were followed up at the outpatient departments of thyroid surgery wards of two tertiary care hospitals in Jiangsu Province, China, between January and March 2023, were subjected to semi-structured interviews. An inductive content analysis was conducted to identify themes. RESULTS: A total of 27 participants, aged 23-56 years, were interviewed. Three themes and eight subthemes were identified: pressure perception including social pressure in the workplace, regular appointments conflict with work schedules, and dilemma of career development; the challenges of self-adjustment including physical disorder, unable to adapt to the pace of work, and unstable mood affects working condition; and lack of social support including lack of access to information or support groups, lack of sympathy and understanding from employers, and lack of professional support. CONCLUSIONS: Our study identified that our participants with differentiated thyroid cancer patients face challenges in trying to return to work or maintain employment within the confines of their disease. Multilevel interventions, ranging from employer and co-worker understanding to information, psychological and other support from health care professionals, can facilitate the process of returning to work and help patients reconcile illness and work.

Trajectory analysis of the work and life experience of healthcare workers during the COVID-19 pandemic: a longitudinal qualitative study.

BACKGROUND: The COVID-19 pandemic has posed a global health threat and has had a profoundly negative impact on the work and lives of healthcare workers. However, few people know how their experiences have evolved over time. AIMS: To describe healthcare workers' experiences during clinical responses to COVID-19 and how they changed over time. DESIGN: A longitudinal qualitative study. METHODS: We undertook a series of four semi-structured qualitative interviews of 14 healthcare workers called as 1st responders to the COVID-19 pandemic. Participants were recruited through purposive snowball sampling. Interviews were undertaken between May 2020 and May 2022 and trajectory approach was used to reveal individual experiences over time. This paper follows the COREQ (Consolidated criteria for Reporting Qualitative Research) guidance. RESULTS: Data analysis yielded the following four themes: (1) Changes in emotions; (2) Changes in organization and management of care; (3) Changes in knowledge and capabilities; and (4) Changes in outlook on life and career. CONCLUSION: Healthcare workers have become stronger in the pandemic and have demonstrated a high degree of professional loyalty and responsibility. However, there is a need to focus on the issue of jealousy and create a harmonious and safe work environment to reduce harm to healthcare workers. Additionally, human resource management strategies must support well-being of healthcare workers and maximize the efficiency of human resource utilization to enable them to respond to current and future needs and emergencies.

Psychological distress and academic self-efficacy of nursing undergraduates under the normalization of COVID-19: multiple mediating roles of social support and mindfulness.

BACKGROUND: Nursing undergraduates' academic self-efficacy is a significant factor in determining their learning motivation, cognition, and emotions. It has a significant impact on improving academic performance and achieving learning goals. METHODS: To explore the mechanism of psychological distress affecting the academic self-efficacy of nursing undergraduates, the generalized anxiety disorder scale-7, patient health questionnaire-9, academic self-efficacy scale, perceived social support scale and mindful attention awareness scale were conducted. RESULTS: Model fitness indexes of the structural equation model is good (CMIN/DF = 1.404, RMSEA = 0.042, GFI = 0.977, IFI = 0.977, TLI = 0.954, CFI = 0.975, NFI = 0.923). Structural equation model analysis showed that social support and mindfulness were the mediating variables of psychological distress on academic self-efficacy. Mediating variables accounted for 44% of the total effect value (- 0.3) with a value of - 0.132. Three paths were verified: psychological distress indirectly affected academic self-efficacy through social support (- 0.064); psychological distress indirectly affected academic self-efficacy through mindfulness (- 0.053); psychological distress indirectly affected academic self-efficacy through social support and mindfulness (- 0.015). CONCLUSIONS: Social support and mindfulness play significant mediating roles in the effect of psychological distress on academic self-efficacy, and the chain mediating role of social support and mindfulness is also significant. Educators may mitigate the impact of psychological distress on academic self-efficacy by enhancing students' social support and mindfulness.

The effect of death education course utilizing constructivist learning theory on first grade undergraduate nursing student attitudes and coping abilities towards death: A mixed study design.

Inadequate clinical preparation for palliative care is often reflected in inadequate education about death. Nursing students as nurses of the future, it is necessary to make them aware of death and overcome fear of it so that they can cope with their future careers and provide qualified and warmly care service. OBJECTIVES: To determine the effect of death education course using constructivist learning theory on first grade undergraduate nursing student attitudes and coping abilities towards death. DESIGN: This study was designed using a mixed-methods design. SETTING: Two campuses of a university school of nursing in China. PARTICIPANTS: First grade Bachelor of Nursing Science students (n = 191). METHODS: Data collection includes questionnaires and reflective writing as after class task. Quantitative data were analyzed using descriptive statistics, the Wilcoxon Signed Rank test, and the Mann-Whitney U test. As for reflective writing, content analysis was hired to analysis. RESULTS: The intervention group's attitude towards death tended to be neutral acceptance. The intervention group's ability to deal with death (Z = -5.354, p < 0.001) and expression of thoughts about death (Z = -3.89 b, p < 0.001) greater than that of the control group. Four themes (Awareness of death before class, Knowledge, The meaning of palliative care, New cognition) were identified from reflecting writing. CONCLUSION: Compared with the conventional teaching, death education course utilizing constructivist learning theory was found to be a more effective method for developing students' death coping skills and reducing fear of death.

Relationship between Anxiety, Depression and Learning Burnout of Nursing Undergraduates after the COVID-19 Epidemic: The Mediating Role of Academic Self-Efficacy.

BACKGROUND: Although cross-sectional studies on the learning status of nursing undergraduates during the COVID-19 epidemic have surged, few studies have explored the normalization of COVID-19 on students' learning burnout and mental health. The study was designed to investigate the learning burnout of nursing undergraduates in school under the normalization of the COVID-19 epidemic and explore the hypothesized mediation effect of academic self-efficacy in the relationship between anxiety, depression and learning burnout in Chinese nursing undergraduates. METHODS: A cross-sectional study was conducted among nursing undergraduates in the school of nursing of a university in Jiangsu Province, China (n = 227). A general information questionnaire, College Students' Learning Burnout Questionnaire, Generalized Anxiety Disorder Scale (GAD-7), and Patient Health Questionnaire depression scale (PHQ-9) were administered. Descriptive statistical analysis, Pearson correlation analysis, and multiple linear regression analysis were performed via SPSS 26.0. Process plug-in (Model 4) was used to test the mediating effect of academic self-efficacy (bootstrap 5000 iterations, α = 0.05). RESULTS: Learning burnout (54.1 ± 0.656) was positively correlated with anxiety (4.6 ± 0.283) and depression (5.3 ± 0.366) (p < 0.01) and was negatively correlated with academic self-efficacy (74.41 ± 0.674) (p < 0.01). Academic self-efficacy plays a mediating role between anxiety and learning burnout (0.395/0.493, 80.12%) and a mediating role between depression and learning burnout (0.332/0.503, 66.00%). CONCLUSION: Academic self-efficacy has a significant predictive effect on learning burnout. Schools and teachers should strengthen the screening and counselling of students' psychological problems, detect learning burnout caused by emotional problems in advance and improve students' initiative and enthusiasm for learning.

Adaptive control for downhole nuclear magnetic resonance excitation.

Nuclear magnetic resonance (NMR) measurements are performed with the pulse sequence and acquisition parameters set by the operator, which cannot be adjusted in real time according to sample characteristics. In one acquisition cycle, usually thousands of high-power pulses are transmitted and thousands of echo points are acquired. The power consumption cause the RF amplifier to overheat, and large amounts of acquired data may be invalid. Therefore, the optimization of excitation and acquisition processes is necessary to improve measurement efficiency. We explore a scheme for the real-time measurement of the samples by adaptively regulating the pulse sequence, which adapts the variable TE pulse sequence as the reconnaissance mode. The appropriate pulse sequence and reasonable parameters (NE, TE) can be selected according to the relaxation characteristics of the samples.This adaptive control strategy has great significance in guiding both dynamic and static measurements, and it is especially suitable for occasions where low magnetic field gradients and diffusion terms can be ignored. We also design a test circuit for adaptive control, which has the function of automatic parameter adjustment. By adjusting parameters such as the number of refocusing pulses, echo spacing, etc., the effective measurement of the samples can be achieved in practice.

Barriers and Facilitators to the Choice of Active Surveillance for Low-Risk Papillary Thyroid Cancer in China: A Qualitative Study Examining Patient Perspectives.

Background: Internationally, several clinical practice guidelines recommend active surveillance as a nonsurgical management strategy for select patients with low-risk papillary thyroid carcinoma. However, patient's decision making when choosing active surveillance as a management approach is not well understood. Thus, our aim was to examine the barriers and facilitators to selecting active surveillance among patients with low-risk papillary thyroid carcinoma in China. Methods: Thirty-nine participants diagnosed with low-risk papillary thyroid carcinoma were purposively recruited between July and November 2021 for semistructured interviews; 24 of whom rejected and 15 patients chose "active surveillance" as a management approach in our sample. Inductive content analysis illustrated emerging themes. Audit trails, member checks, and thematic discussions were used to assert rigor. Results: Barriers and facilitators were classified as patient-related, disease-related, and external factors. Patient-related factors included patient's knowledge, attitudes, and emotions. Disease-related factors included the response to having cancer, the constant state of being diseased, and perceived value of the thyroid gland. External factors included the residual effects of surgery, the active surveillance protocol, and physicians' recommendations. Conclusions: Patient's acceptability of the active surveillance as a management approach are complex with many influencing factors. The public acceptance of active surveillance as a disease management approach needs to be improved, through the presentation of active surveillance as an evidence-based and optimized dynamic management strategy. Clinicians must address their patients' psychological struggles when patients choose active surveillance and patients require more attention and supportive intervention.

Severe Loneliness and Isolation in Nursing Students during COVID-19 Lockdown: A Phenomenological Study.

In 2022, COVID-19 continued to spread across the globe, and to stop the spread of the virus and protect people's health, universities across China continued to remain in a lockdown state. Loneliness is an important topic among college students, and the coronavirus pandemic has exacerbated loneliness. This prolonged school lockdown was unprecedented and it caused severe social isolation and emotional loneliness for students. Few people know how nursing students experience loneliness and find a way through their experience. This qualitative phenomenological study was conducted to reveal the lived experiences of nursing students who indicated COVID-19 lockdown-related loneliness in a previous quantitative survey. We performed 20 semi-structured interviews with nursing students aged 19-23 yrs during their lockdown (April 2022 to June 2022). Our research applied Colaizzi's seven-step data analysis processes to reveal shared patterns in terms of how nursing students experienced lockdown and found the following four themes: emotional challenges associated with loneliness; causes of loneliness; positive and negative motivation to learn; and accepting solitude and reconstructing real life.

Ethical challenges of death faced by nursing undergraduates in clinical practice: A qualitative study.

BACKGROUND: The characteristics of nursing work determine that nursing practice is inseparable from ethical considerations and decision-making. Nursing students have difficulty in dealing with death and it is necessary to explore the ethical challenges faced by nursing undergraduates in the process of clinical practice of nursing dead or dying patients. OBJECTIVE: To explore the ethical challenges faced by undergraduate nursing students in nursing of dead or dying patients. DESIGN: This study was conducted with a phenomenological approach in a qualitative design. SETTINGS, PARTICIPANTS, METHODS: The purposive sample of the study consisted of 35 nursing undergraduates in their last year of education at the bachelor level in nursing who had experience of clinical practice. They voluntarily participated in the study. Data were collected through semi-structured interviews and analyzed using the Colaizzi analysis method. RESULTS: Through analysis of interviews, four themes were identified: (1) Distant death is coming-inadequate preparation; (2) Making decisions between the needs of different positions-difficult balance; (3) Experience a patient's death up close-irresistible resistance; (4) Providing bereavement care after a patient's death-insurmountable obstacle. CONCLUSION: This study shows that nursing undergraduates face ethical challenges in the process of caring for dead or dying patients and the early identification of these ethical challenges is of great significance. University and hospital leaders should pay attention to the ethic and death education of nursing undergraduates so as to help nursing students prepare for clinical practice.

Optimization of shaped pulses for radio frequency excitation in NMR logging.

The radio frequency (RF) excitation pulse of the nuclear magnetic resonance (NMR) logging tool can realize slice measurement by designing shaped pulses. In the case of a certain main magnetic field, the accuracy of the shaped pulse design has a very important impact on the signal-to-noise ratio (SNR) of the NMR signal and the measurement of the short relaxation signal. Hard pulse excitation will produce an undesirable infinite number of side lobes that may perturb the spins in unwanted regions. Soft pulse can achieve selective excitation and has a better slice profile and shorter energy release time while it is not conducive to the measurement of short relaxation signals. This article focuses on the design of shaped pulses in extreme downhole environments and analyzes the characteristics of the three shaped pulses in the two cases of equivalent bandwidth and equivalent pulse duration. At the same time, a kind of RF-shaped pulse transmitting circuit with phase difference control is realized. According to the pulse type optimization strategy, the appropriate shaped pulse is selected. When echo spacing (TE) >0.6 ms, the SNR can be increased to more than 12%. When TE is small, it will automatically switch to the hard pulse mode, which is good for short relaxation measurement.

JNK Signaling Pathway Mediates Fluoride-Induced Upregulation of CK1α during Enamel Formation.

Fluorosis is a defect in the enamel mineral content caused by excessive fluoride intake during amelogenesis; the interaction of various factors in the development and progression of fluorosis has not been defined. Casein kinase 1α (CK1α) is constitutively active in cells and is involved in diverse cellular processes; however, its expression in fluorosis has not been measured. This study aimed to investigate the effects of fluoride on CK1α expression and to assess the regulation of molecular signaling involving fluoride and CK1α during enamel development. Kunming mice were randomly divided into the control and F groups with induced clinical features of fluorosis. The F group mice, including mothers and newborns, were treated with 50 ppm fluoridated water. Immunohistochemical staining of the sections of the embryonic mandible regions was performed at the bell stage. Protein expression and signaling pathways in a mouse-derived ameloblast-like cell line (LS8) exposed to fluoride or a Jun N-terminal kinase (JNK) inhibitor were compared to those in control cells without exposure. CK1α and proteins of the JNK signaling pathways were assayed by quantitative real-time PCR and Western blotting. Mice of the F group developed dental fluorosis. Scanning electron microscopy showed a significant reduction in the degree of mineralization in the F group mice, which manifested as thin, loosely arranged, and disorganized enamel rods. Additional analysis revealed that the expression of CK1α in the F group was significantly elevated compared with that in the control group; LS8 cells responded to fluoride by upregulation of CK1α expression through the JNK pathway. Our findings identified the potential effects of CK1α on fluorosis using a mouse model and revealed that a high fluoride level increases the expression of CK1α and that JNK can be a key regulatory factor in CK1α expression.

Long non-coding RNA LINC00511/miR-150/MMP13 axis promotes breast cancer proliferation, migration and invasion.

Breast cancer is the most common cancer affecting women and one of the leading causes of cancer-related deaths worldwide. In existing studies, some long non-coding RNAs (lncRNAs) are considered to have important regulatory roles in the development of cancers. However, the pathogenic significance of LINC00511 in breast cancer is unclear. In this study, LINC00511 was significantly up-regulated in breast cancer, and its expression level was correlated to poor prognosis of patients with breast cancer. To further study the role of LINC00511 in breast cancer, we knocked down the expression of LINC00511 using siRNAs. Cells transfected with siRNA-2 proliferated, and its metastasis was suppressed. RNA-seq analysis revealed 182 potential targets for LINC00511. The in-silico analysis revealed that differently expressed genes were closely related to signaling mediated by p38-alpha and p38-beta. Subcellular localization showed that LINC00511 was mainly located in the cytoplasm, and knocking down the LINC00511 gene could down-regulate the expression of MMP13. Using bioinformatics analysis combined with dual-luciferase report assay, we finally determined that miR-150 was the direct target of LINC00511. The dual-luciferase report assays also showed that MMP13 was the target of miR-150. LINC00511 knockdown significantly reduced MMP13 protein levels, and miR-150 gene knockdown significantly rescued the down-regulation of MMP13 caused by LINC00511 gene silencing. Moreover, silencing MMP13 and overexpression of miR-150 could reduce the proliferation of breast cancer cells. In conclusion, our data show that LINC00511 is a breast cancer promoter, and the LINC00511/miR-150/MMP13 axis may be a new therapeutic strategy for breast cancer patients.

Immunohistochemical Localization of Fam83h During Fluorosis-induced Mouse Molar Development.

The clinical and pathological features of fluorosis are similar to amelogenesis imperfecta (AI) caused by FAM83H mutations, suggesting that excess fluoride could have effects on the expression of Fam83h. Our previous study found that Fam83h was downregulated by fluorosis induction in ameloblasts; the purpose of this study was to underline the importance of understanding the relationship between fluoride administration and Fam83h expression in vivo. A total of 80 healthy female adult Kunming mice were randomly divided into control group or F group that induced the clinical features of fluorosis. Immunohistochemical staining on sections of the embryo mandible regions was performed at different developmental stages. Mouse primary ameloblast-like cells of the two groups at E13.5, E15.5, and E18.5 were cultured and examined for the expression of Fam83h. The expression of Fam83h in the F group was significantly lower than that in the control group; however, Fam83h was observed clearly in the whole enamel organ in the control group. Our findings shed new light on the potential effects of Fam83h in fluorosis using a mouse model and revealed that high fluoride decreased the expression of Fam83h. This may be one of the reasons for the occurrence of fluorosis.

Simvastatin improves oral implant osseointegration via enhanced autophagy and osteogenesis of BMSCs and inhibited osteoclast activity.

Dental implants have become a widely accepted and successful treatment for fully and partially edentulous patients. Simvastatin has been applied to improve and accelerate the osseointegration of implants by increasing the quantity and quality of bone tissue. However, its potential mechanism has not been elucidated completely. Here, we found that simvastatin significantly enhanced the autophagy level of jaw-derived bone marrow stromal cells (BMSCs) and alleviated production of reactive oxygen species under unfavourable conditions. Simvastatin promoted osteogenic differentiation of BMSCs via enhanced autophagy. Furthermore, simvastatin inhibited the bone resorption activity of osteoclasts. With the use of a rat model of oral implant osseointegration, we found local injection of simvastatin displayed more new bone formation at the interface of the bone and implant compared with that of oral administration. Fluorochrome labelling histomorphometrical analysis and micro-CT also showed that simvastatin promoted the osseointegration of implants. Notably, fewer activated osteoclasts were observed in the region of osseointegration of implants from the simvastatin treatment groups, especially the local delivery of simvastatin. Collectively, our results revealed that simvastatin can increase osteoblastic differentiation of BMSCs via enhanced autophagy and decreased osteoclast activity. Thus, simvastatin could be a viable and promising drug to improve and even accelerate the osseointegration of a dental implant.

Active Ankle Movement May Prevent Deep Vein Thrombosis in Patients Undergoing Lower Limb Surgery.

BACKGROUND: Our aim is to investigate the effect of active ankle movement to prevent deep vein thrombosis (DVT) in patients who received lower limb surgery, and to provide a theory of evidence for rehabilitation nursing of patients after orthopedic surgery. METHODS: Between January 2012 and December 2013, a total of 174 patients were randomized as case group (n = 96) and control group (n = 78). Case group received routine nursing and active ankle movement (30 times/min, 1-7 days after surgery), while control group only received routine nursing. The symptoms and signs of DVT were in real-time observation during the experiment. Thigh and crus circumference, maximum venous outflow (MVO), maximum venous capacity (MVC), and MVO ratio (MVO ratio = MVO/MVC) in the two groups were measured 1-7 days after surgery. Six-month follow-up study was also conducted to observe the occurrence of DVT. RESULTS: Our study revealed that thigh circumference in the case group decreased compared with the control group in 5-7 days (fifth day: 39.98 ± 3.25 vs. 41.01 ± 3.38, P = 0.043; sixth day: 38.21 ± 3.81 vs. 39.49 ± 3.79, P = 0.029; seventh day: 37.13 ± 3.15 vs. 38.76 ± 3.31, P = 0.001), and crus circumference in the case group also decreased compared with the control group in 5-7 days (fifth day: 26.35 ± 2.11 vs. 27.01 ± 2.19, P = 0.045; sixth day: 25.99 ± 2.31 vs. 26.88 ± 3.12, P = 0.032; seventh day: 25.56 ± 1.99 vs. 26.38 ± 2.89, P = 0.028). MVO and MVC in the case group increased compared with the control group 7 days after surgery (MVO: 15.01 ± 2.56 vs. 14.12 ± 2.56, P = 0.024; MVC: 10.18 ± 3.15 vs. 8.91 ± 2.78, P = 0.006). Significant difference in the incidence of thrombus and DVT were found between the case group and the control group 1-7 days after surgery (thrombus: 1.0% and 7.7%, P = 0.027; DVT: 7.6% and 18.4%, P = 0.032). CONCLUSION: Our result manifested that active ankle movement can relieve the swelling of patients after lower limb surgery, and improve the MVO and MVC of patients to prevent formation of DVT after lower limb surgery.
