Objective:To evaluate the application effect and long-term benefits of in situ simulation combined with the forgetting curve training mode in trauma nurse training, and to provide a basis for further promoting the development of trauma nurse training.Methods:From June to September 2022, a total of 78 nurses in the Trauma Center of a grade A tertiary hospital in Changsha, China were selected by the purposive sampling method as the research objects. The nurses were divided into an experimental group and a control group according to the random number table method. The control group received theoretical teaching and skill operation training by traditional teaching methods. The experimental group was trained by the teaching method of in-situ simulation combined with the forgetting curve. The scores of theoretical and operational skills of the two groups were compared by the repeated measures analysis of variance (ANOVA) before training (T1), 1 day after training (T2), 1 month after training (T3), and 6 months after training (T4). The scores of core competence of trauma nurses before and after training were compared between the two groups by the t test. Results:There was no significant difference in theoretical, operational, and core competence scores between the two groups before training ( P>0.05). The results of repeated measures ANOVA showed significant differences in the time effect, inter-group effect, and interaction effect of theoretical and operational scores between the two groups ( P<0.001). The results of one-way repeated measures ANOVA showed that the theoretical and operational scores of the two groups increased first and then decreased with time. The results of multivariate ANOVA showed no significant difference in theoretical and operational scores between the two groups at observation time point T1 ( P>0.05), but significant differences at observation time points T2, T3, and T4, at which the scores in the experimental group were higher than those in the control group ( P<0.001). The results of independent samples t test showed that the core competence score of trauma nurses in the experimental group was significantly higher than that in the control group after training ( P<0.05). Conclusions:The training mode of in situ simulation combined with the forgetting curve is more effective than traditional training mode in improving the professional skill level of trauma nurses and brings long-term training effect and benefits.

BACKGROUND: There is a certain correlation between vitamin nutritional status and cancer patients. Studies have shown that vitamin deficiency increases the risk of cancer. The purpose of this study is to understand the vitamin D nutritional status of cancer patients and to provide scientific basis for further nutritional intervention. METHODS: Cancer patients who visited Shandong Cancer Hospital from July 2017 to June 2019 were included in this retrospective study. Serum 25-hydroxyvitamin D [25(OH)D] concentrations were measured. Univariate analysis and multiple linear regression analysis were carried out using SPSS 20.0. RESULTS: A total of 2,487 cancer patients were evaluable for this analysis. Mean 25(OH)D concentration was (12.70±6.82) ng/mL; the prevalence of vitamin D deficiency [25(OH)D concentration less than 20.00 ng/mL] was of 92.20%. In univariate analysis, age, body mass index (BMI), season and types of cancer were associated with 25(OH)D concentrations. In the multivariate analysis, BMI (β=0.71), age (β=-0.56), season (β=-0.99 for winter; β=-0.76 for autumn vs summer) and types of cancer (β=-1.17 for lung cancer; β=-1.45 for esophageal-gastric cancer; β=-1.05 for colorectal cancer vs other types of cancer) were independently and significantly associated with 25(OH)D levels (P<0.05). CONCLUSIONS Vitamin D deficiency was highly prevalent among cancer patients. Age, BMI, season and types of cancer may be associated with 25(OH)D levels, which indicate that monitoring of vitamin D level for cancer survivor should be taken into account.

Background::High sodium intake is an important risk factor for hypertension and cardiovascular disease. However, the association between gut microbiota composition and metabolomic profiles with dietary sodium intake and blood pressure (BP) is not well-understood. The metabolome, microbiome, and dietary salt intervention (MetaSalt) study aimed to investigate microbial and metabolomic profiles related to dietary sodium intake and BP regulation.Methods::This family-based intervention study was conducted in four communities across three provinces in rural northern China in 2019. Probands with untreated prehypertension or stage-1 hypertension were identified through community-based BP screening, and family members including siblings, offspring, spouses, and parents were subsequently included. All participants participated in a 3-day baseline examination with usual diet consumption, followed by a 10-day low-salt diet (3 g/d of salt or 51.3 mmol/d of sodium) and a 10-day high-salt diet (18 g/d of salt or 307.8 mmol/d of sodium). Differences in mean BP levels were compared according to the intervention phases using a paired Student's t-test.Results::A total of 528 participants were included in this study, with a mean age of 48.1 years, 36.7% of whom were male, 76.8% had a middle school (69.7%) or higher (7.1%) diploma, 23.4% had a history of smoking, and 24.4% were current drinkers. The mean arterial pressure at baseline was 97.2 ± 10.5 mm Hg for all participants, and significantly decreased during the low-salt intervention (93.8 ± 9.3, P < 0.0001) and subsequently increased during the high-salt intervention (96.4 ± 10.0, P < 0.0001). Conclusions::Our dietary salt intervention study has successfully recruited participants and will facilitate to evaluate the effects of gut microbiota and metabolites on BP regulation in response to sodium burden, which will provide important evidence for investigating the underlying mechanisms in the development of hypertension and subsequent cardiovascular diseases.Trial registration::The study was registered in the Chinese Clinical Trial Registry database (ChiCTR1900025171).

Objective: To investigate the clinical practicability and prognostic value of Helsinki CT score in patients with traumatic brain injury (TBI). Methods: A retrospective case series study was conducted to analyze the clinical data of 124 TBI patients admitted to First Affiliated Hospital of Xinjiang Medical University from September 2016 to October 2018. There were 91 males and 33 females, aged 14-84 years, with an average age of 49 years. Glasgow coma score (GCS) at admission ranged from 3-8 points in 45 patients, 9-12 points in 42 patients, and 13-15 points in 37 patients. According to Glasgow outcome scale (GOS) at 6 months after injury, 26 patients were classified into the poor prognosis group with GOS of 1-3 points and 98 patients were in the good prognosis group with GOS of 4-5 points. The prognosis-related risk factors were analyzed, and the role of Helsinki CT score to predict the adverse prognosis and mortality of TBI patients in the two groups was investigated. The sensitivity and specificity of Helsinki CT Score for 6-month poor prognosis were evaluated by receiver operation characteristic (ROC) curve and area under the curve (AUC). Results: Univariate analysis suggested that there were significant differences in terms of subdural hematoma, intracranial hematoma, extradural hematoma, hematoma volume >25 cm^3, intraventricular hemorrhage and suprasellar cistern pressure between the poor prognosis group and good prognosis group (P<0.05). Multivariate logistic regression analysis showed that the mortality and bad prognosis were related to the hemorrhage of ventricles, the pressure of suprasellar cistern and the disappearance of suprasellar cistern in the poor prognosis group and the good prognosis group (P<0.05), while intracranial hematoma and hematoma volume showed no association with mortality and poor prognosis (P>0.05). The Helsinki CT score could independently predict the adverse prognosis and mortality of TBI patients at 6 months (multivariate logistic regression: OR_death=1.21, OR_{adverse prognosis}=1.14). Helsinki CT score had a better predictive ability of 6-month mortality (AUC=0.85) than that of 6-month adverse prognosis (AUC=0.76), and had a predictive value for 6-month mortality and adverse prognosis. Conclusions Subdural hematoma, extradural hematoma, intraventricular hemorrhage and suprasellar cistern state (compression or disappearance) are the risk factors for the poor prognosis of TBI patients. Intraventricular hemorrhage and suprasellar cistern state are the main risk factors for predicting the mortality of 6 months. Helsinki CT score can independently predict the adverse prognosis and mortality of TBI patients at 6 months, and has relatively better value in predicting the mortality.

Objective To investigate the effect of pre-implanted anti-adhesion patch under laparoscopic approach in a Miles' operation on the incidence of parastomal hernia in elderly patients.Methods A total of 68 patients with low rectal cancer admitted into our general surgery department were enrolled in the study from January 2012 to January 2015.All patients received laparoscopic assisted Miles operation.According to whether or not the pre-implanted anti adhesion patch was used during the operation,the 68 cases were divided into pre-implanted patch group(n=38)and the non-implanted patch group(n=30).The operation states,postoperative complications,complications during follow-up and 3-year survival rate were compared between the two groups.Results The operation duration was longer in the pre-implanted patch group than in the non-implanted patch group[(235.7± 33.6)min vs.(94.3±28.9)min,t =5.36,P=0.000].The incidence of complications was lower in the pre implanted patch group than in the non-implanted patch group at 3 years after operation[10.5％ (4/38)vs.90.0％(27/30),x2 =42.69,P =0.000].The local recurrence rate,distant metastasis rate and 3-year overall survival rate had no significant difference between the two groups[23.7 ％ (9/38)vs.23.3％ (7/30),31.6％ (12/38) vs.33.3％ (10/30) and 71.1％ (27/38) vs.70.0％ (21/30)respectively,x2=0.06,0.02 and 0.01,P=0.800,0.878 and 0.925].Conclusions Pre-implanted anti-adhesion patch under laparoscopic approach can significantly reduce the incidence of parastomal hernia in elderly patients after a Miles' operation,which is worthy of promotion.

Objective To investigate the effect of bone flap reduction on unilateral acute subdural hematoma (ASDH) under intracranial pressure monitoring.Methods A retrospective case control study was conducted to analyze the clinical data of 139 patients with unilateral ASDH admitted to the First Affiliated Hospital of Xinjiang Medical University from July 2014 to December 2017.There were 84 males and 55 females,aged 19-87 years (mean,53 years).At the time of admission,the Glasgow Coma Score (GCS) was 3-5 points in 63 patients and 6-8 points in 76.There were 40 patients with unilateral cavity dilation and 16 cases with bilateral pupil dilation.According to the different surgical methods,the patients were divided into study group (n =61) and control group (n =78).The study group removed the cranial hematoma under cranial pressure monitoring and determined whether to perform bone flap reduction according to the actual intracranial pressure.The control group was treated with craniotomy hematoma removal and standard large bone decompressed craniectomy (DC).The success rate of bone flap reduction in the study group was recorded.The complications at postoperative 3 months and the Glasgow Outcome Score (GOS) at postoperative 6 months were compared.Results All patients were followed up for 1-6 months,average 5.5 months.In the study group,23 patients underwent bone flap reduction,and the bone flap reduction rate was 38％.At postoperative 3 months,the study group showed better efficacy in subdural effusion (9:25),hydrocephalus (7 ∶19),and brain swelling in the skull defect area(5 ∶ 18) than the control group (P ＜0.05).Based on the GOS at 6 months after operation,in the study group,25 patients were with good results,nine with moderate disability,10 with heavy disability,seven with plant survival,and 10 died;in the control group,six patients were with good results,21 with moderate disability,15 with heavy disability,10 with plant survival,and 26 died.The number of patients with good prognosis (good and moderate disability) and the number of deaths in the study group were statistically different from those in the control group (P ＜ 0.05).Conclsion In the treatment of unilateral ASDH,bone flap reduction under intracranial pressure monitoring can reduce the incidence of complications and improve the life quality of patients.
