OBJECTIVE To construct three-class （insufficient， normal， excessive） and two-class （insufficient， normal） models for predicting plasma concentration of valproic acid （VPA）， and compare the performance of these two models， with the aim of providing a reference for formulating clinical medication strategies. METHODS The clinical data of 480 patients who received VPA treatment and underwent blood concentration test at the Xi’an International Medical Center Hospital were collected from November 2022 to September 2024 （a total of 695 sets of data）. In this study， predictive models were constructed for target variables of three-class and two-class models. Feature ranking and selection were carried out using XGBoost scores. Twelve different machine learning algorithms were used for training and validation， and the performance of the models was evaluated using three indexes: accuracy， F1 score， and the area under the working characteristic curve of the subject （AUC）. RESULTS XGBoost feature importance scores revealed that in the three-class model， the importance ranking of kidney disease and electrolyte disorders was higher. However， in the two-class model， the importance ranking of these features significantly decreased， suggesting a close association with the excessive blood concentration of VPA. In the three-class model， Random Forest method performed best， with F1 score of 0.704 0 and AUC of 0.519 3 on the test set； while in the two-class model， CatBoost method performed optimally， with F1 score of 0.785 7 and AUC of 0.819 5 on the test set. CONCLUSIONS The constructed three-class model has the ability to predict excessive VPA blood concentration， but its prediction and model generalization abilities are poor； the constructed two-class model can only perform classification prediction for insufficient and normal blood concentration cases， but its model performance is stronger.

Objective:To evaluate the optimization effect of transcutaneous electrical acupoint stimulation (TEAS) combined with moderate sedation with propofol (TEAS-propofol balanced anesthesia) for gastrointestinal endoscopy.Methods:This was a single-blind randomized controlled trial. American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients, aged 18-64 yr, undergoing elective gastrointestinal endoscopy at the Endoscopic Diagnosis and Treatment Center of the Affiliated Hospital of Qingdao University from May to August 2022, were divided into 2 groups using the block random allocation method: conventional anesthesia group (group C) and TEAS-propofol balanced anesthesia group (group TPB). Patients received moderate sedation with propofol plus routine anesthesia with fentanyl 50 μg in group C. In TPB group, TEAS was performed at bilateral Neiguan, Hegu and Zusanli acupoints before surgery until the end of surgery, and patients received propofol for moderate sedation (Modified Observer′s Assessment of Alertness/Sedation scale score was 3). The efficacy and safety of anesthesia and parameters related to outcomes were observed and recorded.Results:In this study, 66 patients were recruited, with 33 in each group, the failure rate of anesthesia in both groups was 3%, and no reflux or aspiration was found. Compared with group C, no significant changes were found in the patients′ satisfaction on the same day, intraoperative pain response score, incidence of intraoperative adverse reactions (tachycardia, hypertension, bucking and body movement), awake time, consumption of propofol, rate of intraoperative awareness and rate of patients hoping to receive the same anesthesia method again postoperatively ( P>0.05), the patients′ satisfaction was significantly increased on the next day ( P<0.05), the incidence of intraoperative respiratory depression, physician satisfaction, and degree of postoperative dizziness and nausea were significantly reduced ( P<0.05), and the discharge time and time to the complete recovery of normal behavior function was significantly shortened in group TPB ( P<0.05). Conclusions:The combination of TEAS at bilateral Neiguan, Hegu and Zusanli acupoints with moderate sedation using propofol for gastrointestinal endoscopy is not only safe and effective, but also beneficial to the postoperative outcome of patients, and the effect is better than that of conventional anesthesia with propofol and fentanyl.

Objective:To explore the relationship between metabolic score for insulin resistance (METS-IR) and chronic kidney disease (CKD) and albuminuria in the Chinese population.Methods:This cross-sectional study was conducted from January to December 2018 among residents aged 20 to 70 years in ten regions of eight provinces in China; all residents had lived in their region for more than 5 years. Various parameters were measured, included fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin (HbA 1c), blood lipids, renal function, urinary albumin/creatinine ratio (UACR), etc. Data of 5 060 subjects meeting the criteria were included in the study. CKD was defined as estimated glomerular filtration rate (eGFR)<60 ml·min -1·1.73 m -2 or UACR≥30 mg/g. Albuminuria was defined as UACR≥30 mg/g. METS-IR was calculated and categorized into quartiles: Q1, METS-IR≤32.19; Q2, METS-IR 32.20-37.10; Q3, METS-IR 37.11-42.58; and Q4, METS-IR>42.58. The correlation between METS-IR and CKD and albuminuria was analyzed by binary logistic regression, and subgroup analyses were performed. Results:There were 1 266, 1 266, 1 265, and 1 263 participants included in Q1-Q4 groups, respectively. With the increase of METS-IR quartile, various parameters increased, including age, fasting blood glucose, HbA 1c, triglycerides, serum uric acid, waist circumference, body mass index, and systolic and diastolic blood pressure, and the proportion of males also increased (all P<0.05). The proportion of patients with CKD and albuminuria increased significantly with the increase in interquartile range (Q) of METS-IR (all P<0.05). Logistic regression analysis showed that for every 1-unit increment of METS-IR, the risk of CKD and albuminuria were both increased by 2% [for both: odds ratio ( OR)=1.02, 95% confidence interval ( CI) 1.01-1.03]. Compared with the lowest METS-IR group (Q1), the ORs for CKD and albuminuria in the highest METS-IR group (Q4) were 1.57 (95% CI 1.17-2.10) and 1.46 (95% CI 1.09-1.96), respectively. In the subgroup analyses, increased METS-IR was significantly associated with CKD and albuminuria among women (CKD: OR=1.62, 95% CI 1.14-2.31; albuminuria: OR=1.53, 95% CI 1.07-2.18), individuals with HbA 1c<7% ( OR=1.64, 95% CI 1.21-2.23; OR=1.55, 95% CI 1.14-2.11), individuals with eGFR≥90 ml·min -1·1.73 m -2 ( OR=1.78, 95% CI 1.27-2.49; OR=1.80, 95% CI 1.28-2.53), and the Chinese Han population ( OR=1.56, 95% CI 1.13-2.17; OR=1.41, 95% CI 1.01-1.96). Conclusions:METS-IR is significantly associated with CKD and albuminuria in a Chinese population. Furthermore, the higher the METS-IR, the higher the risk of CKD and albuminuria.

Objective : To investigate the status of occupational stress and analyze its influencing factors among frontline employees working in a chemical fiber manufacturing enterprise, so as to provide insights into the development of occupational stress interventions. Methods : The frontline employees working in a chemical fiber manufacturing enterprise were selected as the study subjects using a cluster sampling method in October 2018. The status of occupational stress was investigated using the Chinese version of the effort-reward imbalance ( ERI ) questionnaire. The influencing factors for occupational stress were identified using a multivariable logistic regression model. Results : A total of 1 780 questionnaires were sent out, and 1 115 valid ones ( 62.64% ) were recovered. Among the 1 115 respondents, there were 427 men ( 38.30% ) and 688 women ( 61.70% ), and 71.22% were at ages of 21 to 39 years. There were 561 respondents with < 1 year of service ( 50.31% ), and the longest length of service was 11 years. In addition, there were 1 069 respondents ( 95.87% ) exposed to high noise, and 346 respondents ( 31.03% ) were diagnosed at a high occupational-stress state and 769 ( 68.97% ) at a low state. Multivariable logistic regression analysis identified 5 years or longer of service ( OR=1.540, 95%CI: 1.057-2.245 ) and exposure to high noise ( OR=1.917, 95%CI: 1.004-3.659 ) as risk factors for occupational stress among frontline employees in the chemical fiber manufacturing enterprise. Conclusions There are 31.03% of frontline employees at a high occupational-stress state in the chemical fiber manufacturing enterprise, and a high occupational-stress state is associated with exposure to high noise and 5 years or longer of service.

Objective:To investigate the effects of intervention mapping on cardiopulmonary function for patients with acute heart failure in compensatory period, so as to provide references for their early rehabilitation activities.Methods:A total of 90 patients with acute heart failure admitted to Fuwai Central China Cardiovascular Hospital from October 2018 to October 2019 were enrolled in the present study. They were divided into experimental group and control group according to draw-lots-method, with 45 cases in each group. The control group received the routine care and activity plan, while the experimental group implemented intervention mapping-based stage early rehabilitation program. The indicators included 6MWT, forced expiratory volume in one second (FEV 1), brain natriuretic peptide (BNP) as well as Minnesota Living with Heart Failure Questionnaire (MLHFQ), and the intervention effects were compared between the two groups. Results:There were no significant differences in FEV 1, 6MWT, BNP and MLHFQ scores between the two groups at admission ( P>0.05). On discharge, FEV 1, 6MWT were (2.17±0.44) L, (273.09±55.80) m in the experimental group, significantly higher than (1.94 ± 0.39) L and (236.44 ± 50.99) m in the control group; the plasma BNP were (676.79 ± 78.75) ng/L in the experimental group, significantly lower than (736.05 ± 78.77) ng/L in the control group; in addition, the physical demention, emotional dimenson, other demension scores and total scores of MLHFQ in the experimental group were (65.39 ± 5.02), (67.56 ± 4.99), (66.05 ± 4.16) and (66.33 ± 2.63) points, significantly higher than (59.79 ± 5.94), (64.33 ± 5.93), (62.76 ± 4.47), (62.36 ± 2.98) points in the control group, the differences were statistically significant ( t values were 2.56-6.51, all P<0.05). Conclusions:Designing and implementing stage early rehabilitation program using intervention mapping can promote cardiopulmonary function and quality of life of patients with acute heart failure in compensatory period.

Objective:To explore the chain mediating effect of intrusive thinking and psychological distress on the fear of disease progression and quality of life of kidney transplant recipients, with a view to providing scientific theoretical guidance for effective psychological interventions for kidney transplant recipients.Methods:This study is a cross-sectional study. Convenience sampling was used to select 312 kidney transplant recipients who were followed up in the Outpatient Clinic of the First Affiliated Hospital of University of Science and Technology of China from January to May 2019. Patients were investigated with the General Information Questionnaire, the Fear of Progression Questionnaire, the Impact of Events Scale-Revised Intrusion Subscale, Distress Thermometer and 12-Item Short-Form Health Survey Questionnaire. Mplus 8.3 was used to construct and verify multiple intermediary models.Results:A total of 296 kidney transplant recipients were included in this study. In quality of life, the mental health score was (49.58±8.97) , and the physical health score was (49.90±9.17) . Fear of disease progression, intrusive thinking and psychological distress were all negatively correlated with mental health and physical health of quality of life (the r values were -0.453 to -0.401, P<0.01) . The mediating effect of fear of disease progression on the quality of life was established. The total mediating effect value was -0.273, and the specific mediating effect of intrusive thinking accounted for 46.52%, and the specific mediating effect of psychological distress accounted for 41.76%. The chain mediating effect of intrusive thinking and psychological distress between fear of disease progression and quality of life accounted for 11.72%. Conclusions:The intrusive thinking and psychological distress of kidney transplant recipients are established as a chain mediation between the fear of disease progression and the quality of life. While paying attention to patients' fear of disease, clinical staff should pay attention to assessing patients' intrusive thinking and psychological distress, and take targeted measures to reduce the impact of fear of disease progression on the quality of life.
