ObjectiveTo construct a standardized diagnostic scale for Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease. MethodsLiterature related to Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease was retrieved from CNKI， VIP， and Wanfang databases. Diagnostic information from four diagnostic methods was extracted and standardized， with items having a frequency of ≥15 included in the item pool. A three-round Delphi expert consultation was conducted， screening items using support degree， mean score， rank sum， and coefficient of variation. Item weights were determined using analytic hierarchy process （AHP）， gactor analysis （FA）， and combined weighting method （CWM）. The optimal weighting method was selected by comparing the area under the receiver operating characteristic （ROC） curve （AUC）. The Youden index was calculated to establish the diagnostic cutoff value， which was proportionally scaled. ResultsA total of 102 studies were included. Thirty-five items were incorporated into the item pool. The authority coefficients for the three Delphi rounds were 0.82， 0.85， and 0.86， with coordination coefficients of 0.648， 0.538， and 0.506， respectively. Fifteen items were retained after screening. ROC curve analysis showed the AUC ranking as FA > CWM > AHP. The maximum Youden index was 0.814， corresponding to a diagnostic cutoff of 8.361 （scaled to 40 points）. The final scale adopted a structured diagnostic framework： the symptom dimension requires at least 2 items， and the tongue or pulse dimension requires at least 1 category. ConclusionThis study developed a standardized diagnostic scale for Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease. Core items were screened via the Delphi method， with factor analysis identified as the optimal weighting method through AUC comparison. The diagnostic threshold （40 points） and structured diagnostic framework provide a quantitatively clear， clinically practical tool.

Objective To investigate the association of liver radiodensity with the degree and progression of liver fibrosis in patients with chronic hepatitis B(CHB).Methods A retrospective cohort study was conducted among 114 CHB patients who were hospitalized in The First Hospital of Lanzhou University from January to December 2019,and related clinical data were collected,including laboratory tests and abdominal CT.The metabolic characteristics of the patients were assessed,and liver radiodensity was measured.An analysis of variance was used for comparison of normally distributed continuous data between three groups,and the Kruskal-Wallis H rank sum test was used for comparison of continuous data with skewed distribution between three groups;the chi-square test or the Fisher's exact test was used for comparison of categorical data between three groups.A logistic regression analysis was used to investigate the influencing factors for the degree of liver fibrosis,and the Cox proportional-hazards regression model analysis was used to investigate the influencing factors for the progression of liver fibrosis in CHB.Results Among the 114 patients enrolled,43(37.72％)had no liver cirrhosis,30(26.32％)were suspected of liver cirrhosis,and 41(35.96％)had liver cirrhosis,with a median follow-up time of 538.5(322.75-1 031.50)days.Liver radiodensity on plain scan(odds ratio[OR]=0.81,95％confidence interval[CI]:0.68-0.97,P=0.025),liver radiodensity on contrast-enhanced scan(OR=0.95,95％CI:0.90-0.99,P=0.037),and liver volume(OR=0.99,95％CI:0.98-0.99,P<0.001)were independent influencing factors for the degree of liver fibrosis.The univariate Cox regression analysis showed that the low level of HDL(hazard ratio=2.81,95％CI:1.04-7.54,P=0.041)was associated with the progression of liver fibrosis in CHB patients,and the degree of liver fibrosis,liver volume,and liver radiodensity showed no significant association with the progression of liver fibrosis(all P>0.05).Conclusion In CHB patients,liver radiodensity is an independent influencing factor for the degree of liver fibrosis,and low HDL has a marked influence on the progression of liver fibrosis.

Objective:To explore the clinical characteristics and healthcare burden in patients with McCune-Albright syndrome (MAS).Methods:A cross-sectional study was conducted at the Children′s Hospital, Zhejiang University School of Medicine. Clinical and healthcare burden data were systematically collected through structured questionnaires in 164 children with MAS from February 2022 to May 2023. According to the clinical characteristics, patients were categorized into 3 groups: monosymptomatic, bisymptomatic and trisymptomatic groups. Patients were also divided into 3 groups according to the age of <7, 7-<10 and 10-18 years. Comparative analyses of clinical characteristics and healthcare burden were conducted across age, sex, and symptom categories.Results:The cohort comprised 59 males (36.0%) and 105 females (64.0%) with an age of 4.6 (2.0, 7.4) years. Age stratification revealed 117 cases (71.3%) aged 0-<7 years, 29 cases (17.7%) aged 7-<10 years, and 18 cases (11.0%) aged 10-<18 years. Among monosymptomatic (67 cases, 40.9%), the cohort comprised 32 females (47.8%) and 35 males (52.2%), predominantly presenting with fibrous dysplasia (57 cases, 85.1%). This subgroup showed peak prevalence in the 0-<7 years age range (29 cases (50.9%)). The bisymptomatic cohort (56 cases, 34.1%) consisted of 39 females (69.6%) and 17 males (30.4%), predominantly manifesting fibrous dysplasia with skin hyperpigmentation (25 cases, 44.6%). Peak prevalence occurred in the 0-<7 years subgroup(16 cases (64.0%)). The trisymptomatic cohort (41 cases, 25.0%) consisted of 34 females (82.9%) and 7 males (17.1%), with peak prevalence occurring in the 0-<7 years subgroup (36 cases (87.8%)). The diagnostic journey analysis revealed 94 cases (57.3%) required 1-3 referrals, and 34 cases (20.7%) necessitated >3 referrals from symptom onset to definitive diagnosis. Healthcare expenditure analysis revealed 69 families (42.1%) incurred direct medical costs of 10 000-100 000 CNY, with 11 families (6.7%) exceeding >100 000 CNY. Direct non-medical costs reached of 10 000-100 000 CNY for 62 families (37.8%) and >100 000 CNY for 4 families (2.4%). Productivity loss affected 58 families (35.4%) at 10 000-100 000 CNY and 8 families (4.9%) above 100 000 CNY during the study period.Conclusion:MAS requires increased attention to skeletal manifestations, especially in children aged 0-<7 years. Moreover, the significant financial burden on families necessitates a society-wide support system.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

This article mainly summarizes the research advances in gene-modified mesenchymal stem cells in the treatment of liver diseases， in order to provide new insights and strategies for the clinical treatment of liver diseases.

Objective:To investigate the value of elevated preoperative troponin T (TnT) in predicting perioperative adverse cardiac events in geriatric hip fracture patients.Methods:A total of 273 elderly patients undergoing surgical treatment for hip fracture at Department of Cardiology, Tianjin Hospital between January 2024 and December 2024 were enrolled. Basic demographic information was recorded, and preoperative TnT levels were measured. Patients with elevated preoperative TnT ( n=114) were enrolled into the elevated group, while those with normal TnT ( n=159) were enrolled into the normal group. Fracture types included femoral neck fracture ( n=141) and intertrochanteric fracture ( n=132). The impact of elevated preoperative TnT on perioperative major adverse cardiovascular events (MACEs), as well as the influence of different fracture types on MACEs, were analyzed. Normally distributed continuous data were expressed as Mean±SD and compared by independent samples t-test. Categorical data were expressed as case(%) and compared by χ2 test. Multivariate binary logistic regression analysis was performed. The predictive value of TnT for MACEs was assessed by plotting the receiver operating characteristic (ROC) curve and calculating the area under the curve (AUC). Results:The incidence of perioperative MACEs was significantly higher in the elevated TnT group (21.9%, 25/114) compared to the normal TnT group (3.1%, 5/159), with a statistically significant difference ( χ2=23.95, P<0.001). The comparison of postoperative MACEs incidence between different fracture types showed no statistically significant difference [12.1% (17/141) vs. 9.8% (13/132)] ( χ2=0.34, P=0.560). Multivariate binary logistic regression analysis indicated that elevated TnT level ( OR=8.633, 95% CI: 3.117-23.911, P<0.001) was an independent risk factor for perioperative major adverse cardiovascular events (MACEs), increasing the risk by 7.633 times compared to patients with normal TnT. A TnT threshold of ≥0.028 μg/L predicted MACEs with a sensitivity of 0.600 and specificity of 0.954 (AUC=0.839, 95% CI: 0.751-0.926, P<0.05). Conclusion:Troponin T can serve as an independent predictor of perioperative adverse cardiovascular events in elderly patients undergoing surgery for hip fracture and plays a crucial role in the perioperative cardiovascular risk assessment of these patients.

Objective To investigate the clinical features of chronic hepatitis C(CHC)patients with hepatitis C virus genotype 3(HCV GT3)infection and the risk factors for disease progression.Methods A multicenter retrospective cohort study was conducted among 1 002 CHC patients from 11 clinical centers in Northwest China from December 2017 to November 2023,and according to their genotype,they were divided into GT1,GT2,GT3,and GT6 groups.Clinical features were compared between the patients with different genotypes.The one-way analysis of variance was used for comparison of normally distributed continuous data between groups,and the Scheffe test was used for further comparison between two groups.The Kruskal-Wallis H test was used for comparison of data with skewed distribution between groups;the chi-square test or Fisher test was used for comparison of categorical data between groups.The multivariate logistic regression analysis was used to explore the influencing factors for the progression of CHC to liver cirrhosis.Results In terms of the genotype,there were 427 patients with GT1 infection,242 with GT2 infection,299 with GT3 infection(210 patients with GT3a infection,87 with GT3b infection,and 2 with unclassified genotype),and 34 with GT6 infection.The patients with GT3 infection had a significantly younger age than those with GT1 infection(51.3±0.5 years vs 53.2±0.6 years,P<0.05)or GT2 infection(51.3±0.5 years vs 53.7±0.8 years,P<0.05),and for the patients with liver cirrhosis,the patients with GT3 infection had a significantly younger age than those with GT1 infection(52.1±0.5 years vs 59.4±0.9 years,P<0.001)or GT2 infection(52.1±0.5 years vs 58.1±1.1 years,P<0.001).Among the patients with GT3 infection,male patients accounted for 77.9%and the patients with liver cirrhosis accounted for 46.2%,which were significantly higher than those among the patients with GT1,GT2 or GT6 infection(all P<0.001).At baseline,the patients with GT3 infection had significantly higher levels of alanine aminotransferase(ALT)and aspartate aminotransferase(AST)than those with GT1 or GT2 infection,significantly higher aspartate aminotransferase-to-platelet ratio index(APRI)and fibrosis-4(FIB4)than those with GT1,GT2 or GT6 infection,a significantly lower platelet count(PLT)than those with GT2 or GT6 infection,a significantly higher level of alpha-fetoprotein than those with GT2 or GT6 infection,and a significantly lower level of albumin(Alb)than those with GT6 infection(all P<0.05).There were no significant differences between the patients with GT3a infection and those with GT3b infection in age,sex,the proportion of patients with liver cirrhosis,comorbidities,HCV RNA quantification,PLT,ALT,AST,alkaline phosphatase,Alb,APRI,and FIB-4(all P>0.05).The multivariate logistic regression analysis showed that PLT≤150×109/L(odds ratio[OR]=10.72,95%confidence interval[CI]:5.76-35.86,P<0.001)and Alb≤35 g/L(OR=3.74,95%CI:1.22-11.45,P=0.021)were risk factors for liver cirrhosis.Conclusion Most CHC patients with GT3 infection are male in Northwest China,and compared with the patients with other genotypes,such patients tend to have a younger age of onset and higher degrees of liver inflammation activity and fibrosis.Low PLT and a low level of Alb are risk factors for progression to liver cirrhosis in CHC patients with GT3 infection.

An automated identification method for adolescent schizophrenia based on brain electroencephalogram(EEG)entropy features is proposed for further improving the diagnostic accuracy of adolescent schizophrenia.The raw EEG signals are decomposed into 5 commonly used rhythm bands:Delta,Theta,Alpha,Beta,and Gamma.The permutation entropy,fuzzy entropy,and sample entropy are extracted from each rhythm band and then organized into a feature matrix structured by electrode location×frequency band.Finally,an ECA-CNN model integrating efficient channel attention(ECA)and convolutional neural network(CNN)is constructed for feature classification and realizing the automated identification of adolescent schizophrenia.The results demonstrate that the proposed ECA-CNN model has higher recognition accuracy than the traditional machine learning models,achieving an accuracy of 99.08%,a sensitivity of 99.27%,a specificity of 98.85%,a precision of 99.01%,a F1 score of 99.14%,and a Kappa coefficient of 0.9814.This study provides a new idea and method for the diagnosis of adolescent schizophrenia.

Objective:To explore the experiences of post-traumatic growth in patients with failed assisted reproductive technology (ART), providing a basis for individualized nursing interventions.Methods:This study was a qualitative study. From November to December 2023, purposive sampling was used to select ART failed patients at Reproductive Medicine Center of Affiliated Hospital of Nantong University as participants. Data was collected through semi-structured in-depth interviews, and Colaizzi 7-step analysis method was used to summarize and analyze the data and extract themes.Results:A total of 15 ART failed patients were included, their age was (31.8±3.6) years, years of infertility was (4.7±1.7) years. After analysis, a total of four themes and nine sub-themes were extracted, namely negative emotional experiences in the early stages of trauma (anxiety and depression, psychological stress) ; diversified support systems (family support, social support) ; positive coping styles (positive binary coping between spouses, individual coping) ; post-traumatic growth experiences (mobilizing one's own positive strength, strengthening altruistic awareness, and re-planning the future) .Conclusions:Infertility patients exhibit negative emotions after experiencing ART failure, but also experience post-traumatic growth. Medical and nursing staff should provide targeted guidance based on the psychological state of ART failed patients at different stages to improve their mental health.
