Objective To investigate the differences in BMD,T-scores,lumbar HU values,and modified VBQ scores in patients with thoracolumbar fractures,analyze their correlations,and evaluate their predictive efficacy for thoracolumbar fractures.Methods Patients with thoracolumbar fragility fractures and hospitalized in the Department of Orthopedics at the Second Affiliated Hospital of Kunming Medical University from January 2022 to March 2025 were retrospectively enrolled.Among them,132 eligible patients were divided into the fracture group(n=63)and the non-fracture group(n=69).BMD and T-scores of L1～L4 vertebrae were measured via DEXA,lumbar HU values were obtained from CT scans,and modified VBQ scores were calculated using lumbar MRI.Intergroup comparisons were performed using independent samples t-tests.Pearson's correlation analysis was used to assess the relationships among BMD,T-scores,HU values,and modified VBQ scores.Receiver operating characteristic(ROC)curve analysis was conducted to evaluate their predictive performance for thoracolumbar fractures.Results The fracture group exhibited significantly lower mean BMD,T-scores,and HU values in L1～L4 compared to the non-fracture group,while modified VBQ scores were significantly higher(P<0.001).Correlation analysis revealed a significant positive correlation between BMD,T-scores,and HU values in L1～L4,whereas all three parameters showed a significant negative correlation with modified VBQ scores(P<0.001).The AUC values for predicting thoracolumbar fractures were 0.826(T-score),0.836(BMD),0.759(HU value),and 0.875(modified VBQ score),with optimal cutoff thresholds of-1.65(T-score),0.836 g/cm2(BMD),68.4(HU value),and 3.01(modified VBQ score),respectively.Conclusion BMD,T-scores,HU values,and modified VBQ scores in L1～L4 vertebrae are significantly correlated and can serve as the predictive indicators for thoracolumbar fractures.Among them,the modified VBQ score demonstrates the best predictive performance,making it a valuable auxiliary tool for assessing the vertebral bone quality.

Objective:To adapt and validate the Chinese version of the Supervisory Relationship Questionnaire(SRQ)and evaluate its psychometric properties among supervisees.Methods:Item analysis,exploratory factor anal-ysis(EFA)and confirmatory factor analysis(CFA)were conducted on data from 888 supervisees recruited via on-line platform.Test-retest reliability over a four-week interval was examined in a randomly selected subset of 70 su-pervisees.An additional sample of 367 supervisees completed the Supervisory Relationship Scale(SRS)to evaluate criterion validity.Results:The revised SRQ contained 65 items and 6 factors.Both exploratory factor analysis and confirmatory factor analysis supported six-factor structure(safe base,structure,commitment,reflective education,role model and formative feedback),explaining 66.52％of the variance,with factor loadings of the items ranging from 0.58 to 0.83.The revised SRQ had six factors with good fit indices(x2/df=1.31,GFI=0.81,NFI=0.87,CFI=0.97,TLI=0.90,IFI=0.91,RMSEA=0.03,SRMR=0.05).The scores of the revised SRQ were positively correlated with the scores of SRS(ICC=0.96,P＜0.01).The Cronbach α coefficient of the revised SRQ was 0.97,and the test-retest reliability coefficient(ICC)was 0.74.Conclusion:The SRQ-C demonstrates sound psy-chometric properties,including structural validity,criterion-related validity,internal consistency,and temporal stabil-ity.It is a reliable and valid instrument for assessing supervisory relationships from the supervisee perspective.

Antley-Bixler syndrome (ABS) is a rare developmental malformation, usually caused by mutations in the fibroblast growth factor 2 (FGFR2) or cytochrome P450 oxidoreductase (POR) genes. This article reports an 18-year-old male patient with both ulcerative colitis and ABS to explore the possible association between the two diseases, to raise clinicians' awareness, and to provide reference value for early diagnosis and treatment in the future.

Objective:To explore the application effect of risk anticipation and coping intervention model in patients with cervical spondylosis undergoing anterior decompression and bone grafting with internal fixation.Methods:A convenience sampling method was used to select 132 patients with cervical spondylosis who underwent the aforementioned surgical procedure at the First Affiliated Hospital of Anhui Medical University between January 2022 and June 2024. Patients admitted between January 2022 and March 2023 ( n=66) formed the control group and received routine nursing care, while those admitted between April 2023 and June 2024 ( n=66) formed the observation group and received nursing interventions based on the risk anticipation and coping model. Both groups were followed until three months after discharge. Pain intensity, swallowing function, nutritional status, cervical spine function, and quality of life were compared between the two groups. Results:Pain scores were lower in the observation group than in the control group at 6, 12, 24, and 48 hours postoperatively ( P<0.05) . At 24 and 48 hours postoperatively, the observation group had significantly better scores on the Kubota Water Swallowing Test compared to the control group ( P<0.05) . On the day before discharge and three months post-discharge, body mass index, plasma albumin, total protein, Japanese Orthopaedic Association score, and quality of life score were all significantly higher in the observation group than in the control group ( P<0.05) . Conclusions:The risk anticipation and coping intervention model can effectively reduce postoperative pain and improve swallowing function in patients undergoing anterior decompression and bone grafting with internal fixation for cervical spondylosis. It also promotes the recovery of cervical spine function and enhances quality of life.

Objective: To investigate the effects of lactoprotein iron chelates on rats with iron deficiency anaemia (IDA), so as to provide insights into developing and utilizing novel iron supplements. Methods: Seventy weaning female SPF-graded rats of the SD strain were randomly divided into the control group (A), model group (B), ferrous sulfate group (C), lactoferrin group (D), lactoferrin iron chelate group (E), Casein oligopeptide iron chelate group (F) and whey protein oligopeptide iron chelate group (G), with 10 rats in each group. The rats in group A were fed with normal diet, and the others were fed with poor iron diet for IDA modeling. The corresponding interventions were given by intragastric administration once a day. The iron ion concentrations of group C, E, F and G were 2.0 mg/kg, and the protein and oligopeptide concentrations of group D, E, F and G were 2 000 mg/kg. Body weight and hemoglobin of rats were measured weekly during 21-day intervention. At the end, peripheral blood samples were collected, and blood routine, iron metabolism and liver function indicators were determined. Results: After the intervention, among blood routine indicators, the rats in group C, E, F and G showed elevated hemoglobin, red blood cell, mean corpuscular volume and hematocrit, and decreased free protoporphyrin and mean corpuscular hemoglobin concentration when compared with the rats in group B (all P<0.05); among iron metabolism indicators, the rats in group C, E and G showed elevated serum ferritin, the rats in group C, E, F and G showed elevated serum iron, the rats in group C, D, E, F and G showed decreased unsaturated iron binding capacity and total iron binding capacity when compared with the rats in group B (all P<0.05); among liver function indicators, the rats in group E and G showed decreased alanine transaminase when compared with the rats in group B (both P<0.05). Conclusions Lactoprotein alone could not completely improve IDA in rats compared with traditional iron supplement (ferrous sulfate). Lactoprotein iron chelate, especially whey protein oligopeptide iron chelate, could significantly improve IDA, iron reserve and liver function damage in rats.

Objective:To compare the dosimetric differences between accelerated partial breast irradiation intensity modulated radiation therapy (APBI-IMRT) and whole breast irradiation with simultaneous integrated boost intensity modulated radiotherapy (WBI-SIB-IMRT) for early-stage breast cancer after breast-conserving surgery.Methods:A total of 35 patients with early-stage breast cancer in Jilin Province Cancer Hospital between July 2009 and December 2014 after breast-conserving surgery were enrolled. The targeted regions of APBI-IMRT and WBI-SIB-IMRT were created for each patient. The dosimetric difference comparison of the targeted region and normal tissues was evaluated by using dose volume histogram (DVH).Results:There was no significant difference in the dosimetric comparison of gross tumor volume (GTVtb) and planning gross tumor volume (PGTVtb) after correction of cumulative radiation effect (CRE) between WBI-SIB-IMRT group and APBI-IMRT group (both P > 0.05). The dose of clinical target volume (CTV) and planning target volume(PTV) in APBI-IMRT group was higher than that in WBI-SIB-IMRT group [CTV: (4 720±71) cGy vs. (3 889±79) cGy, t = 3.184, P = 0.027; PTV: (4 675±164) cGy vs. (3 807±199) cGy, t = 2.751, P = 0.032] after CRE correction. Compared with WBI-SIB-IMRT group, the dose of ipsilateral lung tissue and left heart tissue in APBI-IMRT group was decreased after CRE correction [(558.5±8.9) cGy vs. (1 304.9±34.4) cGy, t = -7.328, P = 0.001; (35.5±5.3) cGy vs. (843.0±41.5) cGy, t = -8.137, P = 0.001]. V 5/3.6 Gy, V 10/7.3 Gy, V 15/10.9 Gy, V 20/14.6 Gy, V 25/18.2 Gy and V 30/21.9 Gy of the ipsilateral lung and V 30/21.9Gy, V 40/29.2Gy of left heart in all breast cancer patients after two chemotherapy treatments had significant differences (all P = 0.001). Conclusion:Compared with WBI-SIB, APBI-IMRT can improve the dose distribution in target area and reduce the volume of high dose irradiation in organs at risk.
