Objective:To explore the turnover intention of dental outpatient nurses, and analyze its influencing factors.Methods:From August to September 2021, multi-stage sampling was used to select nurses from 20 stomatology hospitals in 7 geographical regions of North China, East China, South China, Central China, Southwest, Northeast, and Northwest China. The survey was conducted using the General Information Questionnaire, Turnover Intention Scale, Nursing Work Environment Scale, Psychological Capital Scale for Nurses, and Work Engagement Scale.Results:A total of 1 513 questionnaires were collected, including 1 135 valid questionnaires, with a valid rate of 75.02% (1 135/1 513). The total score of turnover intention among 1 135 dental outpatient nurses was (2.22±0.56). Pearson correlation analysis showed a negative correlation between nursing work environment, psychological capital, work engagement, and turnover intention ( r=-0.421, -0.340, -0.446; P<0.01). The structural equation model showed that the nursing work environment had a direct negative effect on the turnover intention of dental outpatient nurses (β=-0.401, P<0.01) and had an indirect negative effect on turnover intention through work engagement (β=-0.106, P<0.01), with a mediating effect of 20.91%. Psychological capital had an indirect negative effect on the turnover intention of dental outpatient nurses through work engagement (β=-0.271, P<0.01), with a mediating effect of 52.83%. Conclusions:The turnover intention of dental outpatient nurses is at a high level. Managers can reduce the turnover intention of dental clinic nurses by improving the nursing work environment, developing psychological capital, and increasing work engagement.

Objective:To investigate the effects of evidence-based precision nursing in patients with sarcopenia undergoing total knee arthroplasty (TKA) .Methods:By convenience sampling, totally 41 TKA patients with sarcopenia treated in the Department of Orthopedics at The First Affiliated Hospital of Zhengzhou University from August 2021 to February 2022 were selected as the control group, and 41 TKA patients with sarcopenia treated from March 2022 to March 2023 as the observation group. Patients in the control group received conventional nursing care, while patients in the observation group received an evidence-based precision nursing plan. The differences in muscle mass, grip strength, physical activity ability, knee joint function, and quality of life between the two groups before and after the intervention were compared.Results:After the intervention, the total muscle mass, affected limb skeletal muscle mass, limb skeletal muscle mass, limb skeletal muscle mass index, and grip strength in the observation group were significantly higher than those in the control group ( P< 0.05). The scores on the Short Physical Performance Battery, Lysholm Score, and Sarcopenia Quality of Life Scale in the observation group were also significantly higher than those in the control group ( P<0.05) . Conclusions:Evidence-based precision nursing can improve postoperative muscle mass and strength, enhance physical activity ability and joint function, and improve the quality of life in TKA patients with sarcopenia.

Objective: To observe the impact of Tiao Shen Tong Du (regulating the mind and unblocking the Governor Vessel) Tuina (Chinese therapeutic massage) on neuropsychological development of premature infants, discover effective early-stage intervention techniques, and improve the prognosis of premature infants.Methods: A total of 115 eligible premature infants were recruited and divided into a control group of 59 cases and an observation group of 56 cases based on different interventions. The control group received three-month physical therapy (PT) and conventional early-stage intervention, and the observation group received additional Tiao Shen Tong Du Tuina treatment. Before and after treatment and at the one-year follow-up, the Gesell developmental schedule was adopted to evaluate neuropsychological development. Results: After treatment, the gross motor development quotient (DQ) was higher in the observation group than in the control group, and the difference was statistically significant (P<0.05); there were no significant differences in the other four domains between the two groups (P>0.05). At the one-year follow-up, the observation group showed more notable improvements in all five domains' DQs than the control group, and the between-group differences were statistically significant (P<0.05 or P<0.01).Conclusion: Based on conventional intervention, Tiao Shen Tong Du Tuina can significantly improve the gross motor function of premature infants in the short term, alongside valid long-term efficacy for gross motor function, fine motor function, adaptive behaviors, language, and personal-social behaviors.

Objective:To evaluate the effects of different position interventions in patients with acute respiratory distress syndrome (ARDS) undergoing mechanical ventilation from the aspects of effectiveness and safety using the method of network Meta-analysis.Methods:Randomized clinical trials (RCTs) related to the therapeutic effect of position interventions in adult ARDS patients undergoing mechanical ventilation were retrieved in PubMed, Embase, Cochrane Library, Web of Science, CINAHL, China Biomedical Literature Database, China National Knowledge Infrastructure, VIP and WanFang Data. The search time limit was from the establishment of the database to January 2021. According to the literature inclusion and exclusion criteria, literature was screened and the quality evaluation and data extraction were carried out. StataSE 15 and Addis 1.16.6 were used for network Meta-analysis.Results:A total of 31 RCTs were included, involving5 positions of prone, semi-recumbent, side-recumbent, supine and sitting, and 3 738 patients. The prone position compared with the semi-recumbent position, the semi-recumbent position compared with the supine position could reduce the 28-day all-cause mortality of the patient, and the difference was statistically significant ( P<0.05) . Compared with the semi-recumbent position and the supine position, the prone position could reduce the length of time the patient stayed in the ICU, and the difference was statistically significant ( P<0.05) . The prone position could increase the oxygenation index of patients compared with the supine position, and the difference was statistically significant ( P<0.05) . For the total incidence of adverse events and adverse reactions, there was no statistically significant difference between any two positions ( P>0.05) . The network Meta probability ranking of all the outcome indicators showed that the prone position and the side-recumbent position had advantages, and the supine position and the semi-recumbent position had no obvious advantages. Conclusions:Current evidence shows that the prone and side-recumbent position interventions are effective and safe for the treatment of ARDS patients undergoing mechanical ventilation, and are good choices among several positions.

Clinical scales and external devices are two important ways to quantify the severity of motor symptoms for Parkinson′s disease (PD). As one representative of scales, the Unified Parkinson′s Disease Rating Scale is considered the "gold standard" in the comprehensive assessment of PD. External devices are divided into electrophysiological and mechanical devices based on the type of sensors. Both sides can monitor the PD motor symptoms objectively. Currently, numerous and ununified parameters of devices make the clinical quantification of PD symptoms still rely on scales. This article reviewed the progress on quantitative assessments of motor symptoms for Parkinson′s disease.

Oral medicine and deep brain stimulation are two main treatments for Parkinson′s disease (PD). But their long-term efficacies are decreasing, which limit the choice of patients in advanced stage. As a special way of sensory intervention, rhythmic cueing can improve gait parameters, reduce freezing of gait severity and improve gait-related mobility by activating the motor pathway directly, repairing internal clock, promoting internal dopamine release and improving cognitive function to maintain gait stability. Rhythmic auditory and visual cueing has a potential in PD treatment.

Maple syrup disease (MSUD) is a rare autosomal recessive disorder caused primarily by mutations of branched-chain keto acid dehydrogenase complex (BCKDC). BCKDC includes at least four pathogenic genes of BCKDHA, BCKDHB, DLD and DBT. The clinical manifestations of MSUD are complex, and the main symptoms at the early stage include difficulty in feeding, drowsiness, change in muscle tone and special urine flavor of maple syrup. As the disease progresses, convulsion, hypoglycemia, coma and systemic failure may occur. MSUD is easily missed or misdiagnosed during the neonatal period. This paper provides a review for recent progress made in research on MSUD including etiology, physiopathology, clinical manifestation, auxiliary examination and treatment, with a particular emphasis on genetic testing and treatment.

Objective: To evaluate the expression of histone H4 acetylation(Ac-H4) during the cleft palates formation induced by 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin(TCDD) in C57BL/6J mice. Methods: Forty-eight pregnant C57BL/6J mice were completely randomly divided into two groups: ① TCDD group, mice were treated with 20ug/kg of TCDD on gestation day (GD) 10.5 by gastric perfusion; ② control group, mice were treated with an equivalent of corn oil. The head samples were collected and sliced in coronal plane on GD13.5, GD14.5 and GD15.5 respectively. Histone H4 acetylation in the palates were evaluated by immunohistochemical staining and Western Blot in the two groups. Results: Histone H4 acetylation was mainly expressed in the palatal epithelial cells and slightly expressed in mesenchymal cells. The expression level of histone H4 acetylation was 0.6002±0.2530, 0.9180±0.0941 and 0.8966±0.0908 respectively in control group on GD13.5, GD14.5 and GD15.5; while 1.0229±0.2779, 1.6095±0.2651 and 1.2758±0.1251 in TCDD group. There were statistically significant differences between the control group and TCDD group (P<0.05). Conclusions The histone H4 acetylation was involved in the cleft palate formation induced by TCDD in C57BL/6J mice.

Objective: To explore the application of dorsal double-wing flap for reconstruction of the web space in the fifth and fourth toe polysyndactyly. Methods: 99 patients (112 feet) with polysyndactyly of the fifth toe fused with the fourth toe were treated, 75 of which were incomplete and 37 were complete fusion of the fourth and fifth toes. The fifth toes showed various degrees of fibular deviation and minor deformities. Excision of polydactyly and then with the use of wedge osteotomy correction deviation. Using 77 traditional and 35 modified dorsal double-wing flap for reconstruction of the web space, and close the lateral sides of toes with flaps from polydactyly. The distal soft tissue of polydactylies were used lengthening the reconstructed fifth toes. Results: Polydactyly excision and syndactyly releasing in same procedure and lateral sides of the toes were all closed with flaps without skin grafts. Patients were followed up average 27 months after operation, the constructed web space showed good appearance, with slightly deeper or normal location. The fibular deviation were complete correction, and minor deformities were improved. Conclusions The dorsal double-wing flap is used for reconstruction of the web space in the fifth and fourth toes polysyndactyly without skin grafts. Reconstruction of the web depth, combined with lengthen distal end of the fifth could improve the toe appearance. Compared with traditional dorsal double-wing flap reconstruction of the web space, the modified flaps have better appearance in palmar of foot.
