Objective To investigate ICU nurses' practice of physical restraints and to explore its influencing factors.Methods Questionnaires were used to investigate 150 ICU nurses from 5 third-grade hospitals in Hengyang City.Results The score of ICU nurses' knowledge of physical restraints was at middle-upper level, while the accuracy rate was 78.70%. The attitude toward physical restraints was neutral. Practice of physical restraints was relatively appropriate and the influencing factors were: age, nursing age, the indications of physical restraints, professional title, feeling of physical restraints, duration of working in ICU and education background of physical restraints.Conclusions The education of physical restraints should be improved, so as to set up the positive feeling of physical restraints, take pertinent measures and improve nursing quality.

OBJECTIVETo explore the best intervention time of acupuncture and moxibustion for peripheral facial palsy (Bell's palsy) and the clinical advantage program of selective treatment with acupuncture and moxibustion.

METHODSMulti-central large-sample randomized controlled trial was carried out. Nine hundreds cases of Bell's palsy were randomized into 5 treatment groups, named selective filiform needle group (group A), selective acupuncture + moxibustion group (group B), selective acupuncture + electroacupuncture (group C), selective acupuncture + line-up needling on muscle region of meridian group (group D) and non-selective filiform needle group (group E). Four sessions of treatment were required in each group. Separately, during the enrollment, after 4 sessions of treatment, in 1 month and 3 months of follow-up after treatment, House-Brackmann Scale, Facial Disability Index Scale and Degree of Facial Nerve Paralysis (NFNP) were adopted for efficacy assessment. And the efficacy systematic analysis was provided in view of the intervention time and nerve localization of disease separately.

RESULTSThe curative rates of intervention in acute stage and resting stage were 50.1% (223/445) and 52.1% (162/311), which were superior to recovery stage (25.9%, 35/135) separately. There were no statistical significant differences in efficacy in comparison among 5 treatment programs at the same stage (all P > 0.05). The efficacy of intervention of group A and group E in acute stage was superior to that in recovery stage (both P < 0.01). The difference was significant statistically between the efficacy on the localization above chorda tympani nerve and that on the localization below the nerve in group D (P < 0.01). The efficacy on the localization below chorda tympani nerve was superior to the localization above the nerve.

CONCLUSIONThe best intervention time for the treatment of Bell's palsy is in acute stage and resting stage, meaning 1 to 3 weeks after occurrence. All of the 5 treatment programs are advantageous to Bell's palsy. In the condition of the limited medical sources, the simple filiform needle therapy is recommended in acute stage. For the patients with the disorder above chorda tympani nerve, the line-up needling on muscle region of meridian is not recommended.

Objective To investigate the role of nasal mucosa fibrosis on radiation induced nasal mucosa injury. Methods Seventy two male rats were randomly divided into two groups, control group and irradiation injured group (radiation dose were 40 Gy);the rats were killed 1 week, 2 weeks, 4 weeks, 8 weeks, 3 months and 6 months after the finish of radiation. The middle turbinates of the animals were removed. The pathological change of the nasal mucosa were observed with scanning electron microscope, transmission electron microscope, hematoxylin and eosin (HE), alcian blue-periodic acid-Sehif (AB-PAS), and Masson Trichrome (MT). The Hyp content in nasal mucosa was measured with chemo-chromatometry. Results After radiation, the pathological characteristics in early stage (within 4 weeks) was acute inflammatory reaction. The repair of nasal mucosa started 4 weeks after radiation, lasted to 6 months. The deposition of collagen in nasal mucosa could be found 1 week after irradiation and increased gradually. Conclusion Irradiation could induce a serials of pathological changes on nasal mucosa. The nasal mucosa fibrosis may be one of the reasons of persistent irradiation induced nasal mucosa injury.

OBJECTIVE To investigate the effect of pharyngeal cavity and genoglossus muscle exercises in patients with mild obstructive sleep apnea syndrome(OSAHS)left over after palatopharyngoplasty with diastolic cardiac dysfunction.METHODS A total of 75 patients with mild OSAHS left after palatopharyngoplasty with diastolic cardiac dysfunction from January 2021 to August 2023 were selected for retrospective study.Among them,37 patients underwent pharyngeal cavity and mentoglossum muscle exercise(observation group),while 38 patients did not(control group).Using postoperative data as baseline value.mean blood oxygen saturation(MSpO2),lowest oxygen saturation(LSpO2),sleep efficiency,apnea index(AI),sleep latency,apnea hypopnea index(AHI),hypopnea index(HI),microarousal index(MAI),rapid eye movement latency,arterial blood pressure of carbon dioxide(PaCO2),pH,arterial partial oxygen pressure(PaO2),left ventricular end-systolic diameter(LVDs),blood lactic acid,left ventricular ejection fraction(LVEF),Tei index,left ventricular end-diastolic diameter(LVDd),daytime Epworth sleepiness scale(ESS)score,Pittsburgh sleep quality index(PSQI)score and incidence of adverse cardiovascular events(MACE)were compared at baseline and 3 months later.RESULTS After 3 months,AHI,HI and AI in observation group were lower than those in control group,and MSpO2 and LSpO2 were higher than those in control group(P<0.05);Sleep efficiency of observation group was higher than control group,daytime ESS score,PSQI score and MAI were lower than control group(P<0.05).There were no significant differences in PaCO2,LVDd,PaO2,blood lactic acid,sleep latency,pH,LVEF,rapid eye movement latency,LVDd,Tei index between the observation group and the control group(P>0.05).The incidence of MACE in the observation group was 5.41%(2/37),compared with 13.16%(5/38)in the control group,there was no significant difference(P>0.05).CONCLUSION In patients with mild OSAHS left after palatopharyngoplasty with diastolic cardiac dysfunction,the exercise of pharyngeal cavity and genoglossus can improve hypopnea,alleviate clinical symptoms and improve sleep quality,but it has limited effect on the improvement of cardiac function.

BACKGROUNDNontraumatic osteonecrosis of the femoral head (NONFH) is a debilitating disease that represents a significant financial burden for both individuals and healthcare systems. Despite its significance, however, its prevalence in the Chinese general population remains unknown. This study aimed to investigate the prevalence of NONFH and its associated risk factors in the Chinese population.

METHODSA nationally representative survey of 30,030 respondents was undertaken from June 2012 to August 2013. All participants underwent a questionnaire investigation, physical examination of hip, and bilateral hip joint X-ray and/or magnetic resonance imaging examination. Blood samples were taken after overnight fasting to test serum total cholesterol, triglyceride, and high-density lipoprotein (HDL) and low-density lipoprotein (LDL) levels. We then used multivariate logistic regression analysis to investigate the associations between various metabolic, demographic, and lifestyle-related variables and NONFH.

RESULTSNONFH was diagnosed in 218 subjects (0.725%) and the estimated NONFH cases were 8.12 million among Chinese people aged 15 years and over. The prevalence of NONFH was significantly higher in males than in females (1.02% vs. 0.51%, χ2 = 24.997, P < 0.001). Among NONFH patients, North residents were subjected to higher prevalence of NONFH than that of South residents (0.85% vs. 0.61%, χ 2 = 5.847, P = 0.016). Our multivariate regression analysis showed that high blood levels of triglycerides, total cholesterol, LDL-cholesterol, and non-HDL-cholesterol, male, urban residence, family history of osteonecrosis of the femoral head, heavy smoking, alcohol abuse and glucocorticoid intake, overweight, and obesity were all significantly associated with an increased risk of NONFH.

CONCLUSIONSOur findings highlight that NONFH is a significant public health challenge in China and underscore the need for policy measures on the national level. Furthermore, NONFH shares a number of risk factors with atherosclerosis.

OBJECTIVE: To investigate the mechanism of self-efficacy between self-management ability and self-management behavior and its differences among patients with different disease courses through mediation tests. METHODS: In the study, 489 patients with type 2 diabetes who attended the endocrinology departments of four hospitals in Shanxi Province and Inner Mongolia Autonomous Region from July to September 2022 were enrolled as the study population. They were investigated by General Information Questionnaire, Diabetes Self-Management Scale, Chinese version of Diabetes Empowerment Simplified Scale, and Diabetes Self-Efficacy Scale. Mediation analyses were performed using the linear regression model, Sobel test, and Bootstrap test in the software Stata version 15.0 and divided the patients into different disease course groups for subgroup analysis according to whether the disease course was > 5 years. RESULTS: In this study, the score of self-management behavior in the patients with type 2 diabetes was 6.16±1.41, the score of self-management ability was 3.99±0.74, and the score of self-efficacy was 7.05±1.90. The results of the study showed that self-efficacy was positively correlated with self-management ability (r=0.33) as well as self-management behavior (r=0.47) in the patients with type 2 diabetes (P < 0.01). The mediating effect of self-efficacy accounted for 38.28% of the total effect of self-management ability on self-management behaviors and was higher in the behaviors of blood glucose monitoring (43.45%) and diet control (52.63%). The mediating effect of self-efficacy accounted for approximately 40.99% of the total effect for the patients with disease course ≤ 5 years, while for the patients with disease course > 5 years, the mediating effect accounted for 39.20% of the total effect. CONCLUSION Self-efficacy enhanced the effect of self-management ability on the behavior of the patients with type 2 diabetes, and this positive effect was more significant for the patients with shorter disease course. Targeted health education should be carried out to enhance patients' self-efficacy and self-management ability according to their disease characteristics, to stimulate their inner action, to promote the development of their self-management behaviors, and to form a more stable and long-term mechanism for disease management.
