Objective To understand the current status of low-density lipoprotein cholesterol (LDL-C) control in patients after coronary artery bypass grafting (CABG). Methods Clinical data of patients who underwent isolated CABG in Beijing Anzhen Hospital in 2023 were collected. All patients returned to our hospital approximately one year after surgery (10-13 months) for a lipid level recheck. We analyzed their LDL-C attainment status and influencing factors. Patients were categorized into two groups based on whether their LDL-C met the target: a LDL-C attainment group and a LDL-C non-attainment group. Results This study included 1456 patients who underwent CABG, including 320 females and 1136 males, with an average age of (61.41±9.12) years. One year post-surgery, 234 patients achieved the LDL-C target, with an attainment rate of 16.07%. The proportion of patients in the LDL-C attainment group who were ultra-high risk (77.35% vs. 92.06%, P＜0.001), female (16.24% vs. 23.08%, P=0.021), and those with comorbid hypertension (55.98% vs. 63.18%, P=0.038) was significantly lower than those in the LDL-C non-attainment group. Additionally, the baseline body mass index (BMI) [(25.37±3.24) kg/m2 vs. (26.03±3.56) kg/m2, P=0.017], total cholesterol levels [(3.30±0.84) mmol/L vs. (4.01±1.03) mmol/L, P＜0.001], LDL-C [(1.62±0.63) mmol/L vs. (2.25±0.85) mmol/L, P＜0.001], and high-density lipoprotein cholesterol [(0.98±0.26) mmol/L vs. (1.02±0.24) mmol/L, P=0.049] upon admission in the attainment group were all lower than those in the non-attainment group. Moreover, the lipid-lowering drug usage rate in the attainment group (100.00% vs. 96.24%, P=0.003) and the proportion using two types of drugs together (25.21% vs. 10.72%, P＜0.001) were both higher than those in the non-attainment group, while the statin monotherapy rate was lower than that in the non-attainment group (74.79% vs. 85.19%, P＜0.001). Logistic regression analysis showed that baseline BMI (OR=0.928, P=0.012) and baseline LDL-C levels (OR=0.207, P<0.001), patient cardiovascular risk stratification (OR=0.155, P<0.001) and lipid-lowering drug treatment regimen (OR=3.758, P<0.001) are significant factors affecting the LDL-C control status. Conclusion The LDL-C compliance rate of patients undergoing CABG is at a relatively low level 1 year after surgery. Patients with very high risk of atherosclerotic cardiovascular disease, high baseline LDL-C levels, and overweight or obesity should be strengthened lipid management. For these patients, the intensity of lipid-lowering drug use or combination medication should be increased upon discharge.

ObjectiveTo explore the clinical potential of magnetic resonance elastography （MRE） for assessing the stiffness of common intracranial tumors. MethodsA retrospective analysis was conducted on 47 patients with brain tumors who underwent surgical treatment at The First Affiliated Hospital of Sun Yat-sen University between April 2023 and September 2024. The cohort included 10 cases of glioma， 12 cases of vestibular schwannoma， and 25 cases of meningioma. All patients underwent multiparameter MRI and MRE preoperatively. After co-registering MRE images with contrast-enhanced 3D T1-weighted images， three regions of interest （ROIs） were placed in the areas of maximum and minimum tumor stiffness respectively to measure the shear stiffness values， and the mean was calculated as the average shear stiffness. Additionally， one ROI was placed in the white matter and one in the grey matter of the posterior horn of the lateral ventricle at the basal ganglia level to obtain normal reference values. A neurosurgeon， blind to the MRE results， graded the intraoperative tumor stiffness based on surgical videos using a 5-point scale （1： soft； 5： hard）. Intraclass correlation coefficient （ICC） was used to assess inter-observer consistency. Analysis of variance （ANOVA） and nonparametric tests were employed to compare the differences of shear stiffness values between groups. Spearman correlation analysis was used to examine the correlation between elasticity values and clinicopathological parameters. The discriminatory efficacy of shear stiffness values for tumor types was evaluated with receiver operating characteristic （ROC） curves. ResultsThe ICCs for elasticity values measured by two physicians in the hardest and softest tumor areas were 0.868 and 0.831， respectively （both P＜ 0.01）. The maximum， minimum， and average shear stiffness values of meningiomas［（1.91±0.28） m/s， （1.66±0.25） m/s， （1.78±0.26） m/s， respectively］ were significantly higher than those of gliomas［（1.59±0.23） m/s， （1.42±0.23） m/s， （1.50±0.22） m/s， respectively （P＜0.05）］. The shear stiffness values of vestibular schwannomas［（1.70±0.30） m/s， （1.51±0.23） m/s， （1.61±0.26） m/s， respectively） were lower than those of meningiomas and higher than those of gliomas， but these differences were not statistically significant （both P＞0.05）. The shear stiffness values of white matter were significantly higher than that of grey matter［（1.63±0.08） m/s vs. （1.39±0.12） m/s， P＜0.05）］. In the overall sample， the maximum， minimum， and average shear stiffness values were significantly positively correlated with the intraoperative hardness grade （r_s = 0.591， r_s = 0.541， r_s = 0.571， respectively； all P＜0.001）， negatively correlated with WHO grade （r_s = -0.458， r_s = -0.458， r_s = -0.480， respectively； all P＜0.01）， but showed no correlation with Ki-67 （all P＞0.05）. ConclusionMRE can be used to assess the stiffness of intracranial tumors and to some extent differentiate between tumor types， which aids in formulating more individualized preoperative surgical plans.

Objective:To evaluate the perioperative application effect of enhanced recovery after surgery (ERAS) clinical pathway in percutaneous vertebro plasty (PVP).Methods:The clinical data of 274 patients who underwent PVP treatment for osteoporotic vertebral compression fracture (OVCF) in Beijing Friendship Hospital, Capital Medical University from May 2023 to August 2024 were retrospectively analyzed. The patients were divided into two groups according to the different numbers of surgical segments: the single-segment group ( n=211) and the multisegment group ( n=63). Patients in the single-segment group underwent single-segment surgery, while patients in the multisegment group underwent surgery on ≥2 segments. The core points of the ERAS clinical pathway adopted in this study include perioperative education, pain management, early mobilization, application of "outfast", and joint guidance from the departments of nutrition and rehabilitation. Comparison was made between the two groups of patients in terms of visual analog scale (VAS) scores for low back pain at preoperative, 2 h, 6 h, 24 h postoperatively, and on the day of discharge; Oswestry disability index (ODI) scores preoperatively and on the day of discharge; time to first ambulation postoperatively, total length of hospital stay, postoperative length of stay, perioperative complications, and perioperative application of Opioid consumption. Measurement data were expressed as mean±standard deviation ( ± s), and the independent sample t-test was used for comparison between groups; count data were expressed as cases and percentage, and the Chi-square test was used for comparison between groups. The VAS pain scores at each stage of the perioperative period were evaluated using repeated measures analysis of variance or generalized estimating equations. Results:Compared with that before the operation [(6.17±0.93) points, (6.29±0.83) points], the VAS scores of low back pain of patients in the single-segment group and the multisegment group at 2 hours after surgery [(3.09±0.82) points, (3.27±0.65) points], 6 hours after surgery [(2.60±0.79) points, (2.62±0.55) points], and 24 hours after surgery [(1.89±0.77) points, (1.97±0.72) points] and on the day of discharge [(1.72±0.71) points, (1.81±0.64) points] were significantly decreased, and the differences were statistically significant ( P<0.05). At the same stage, the VAS scores of low back pain in both groups were not statistically significant ( P>0.05). The ODI scores of patients in the single-segment group and the multisegment group on the day of discharge [(24.21±2.35) points, (24.63±3.31) points] were significantly lower than those before the operation [(64.50±4.81) points, (65.52±4.08) points], and the differences were statistically significant ( P<0.05). There were no statistically significant differences in perioperative complications and the proportion of Opioid drug application between the two groups of patients ( P>0.05). Conclusion:For patients with single-segment or multisegment OVCF, PVP surgical treatment under ERAS clinical pathway management can achieve immediate pain relief, early ambulation exercise, and satisfactory perioperative efficacy.

Objective:To evaluate preoperative malnutrition risk in patients with osteoporotic vertebral compression fracture (OVCF) based on mini nutritional assessment short form (MNA-SF) and analyze the related clinical risk factors.Methods:A cross-sectional study was conducted using clinical data from 129 OVCF patients who underwent percutaneous vertebroplasty at Beijing Friendship Hospital, Capital Medical University, between May 2023 and December 2023. The cohort included 26 males and 103 females, aged (74.71±9.13) years(ranging from 48-98 years). According to MNA-SF scoring method, they were divided into three groups, the malnutrition group ( n=6), the nutritional risk group ( n=40), and the good nutrition group ( n=83). Nutritional risk and malnutrition rates were evaluated using the MNA-SF score. Measurement data with normal distribution were expressed as mean±standard deviation ( ± s) and compared using one-way ANOVA. The comparison between groups of count data was conducted using chi-square test. Univariate analysis and multivariate logistic regression were performed to identify independent risk factors for malnutrition and nutritional risk. Results:According to the MNA-SF score, among 129 patients, the malnutrition rate was 4.7%, the nutritional risk rate was 31.0%, and 64.3% exhibited adequate nutrition based on MNA-SF scores. The results of one-way ANOVA showed that gender ( P=0.023) and BMI ( P<0.001) were significantly correlated with malnutrition and nutritional risk; Logistic regression analysis suggested that the influencing factors of nutritional risk included gender ( P=0.002) and BMI ( P<0.001), while the only dangerous factor of malnutrition was BMI ( P<0.001). Conclusions:Bsed on MNA-SF, OVCF patients undergoing percutaneous vertebroplasty have a higher incidence of malnutrition and nutritional risk. The risk factors for nutritional risk in patients are gender and BMI, while the risk factor for malnutrition is only BMI.

Objective To explore the role of serum N-terminal peptide of type Ⅲ procollagen(PⅢNP),insulin-like growth factor(IGF-1),and N-terminal pro-B-type natriuretic peptide(NTpro-BNP)in the disease evaluation and prognostic prediction in elderly patients with chronic left heart failure(CLHF).Methods A total of 92 elderly patients with CLHF who were admitted to Liyang People's Hospital from March 2020 to March 2023 were selected as research objects.There were 34 cases of Class Ⅱ,29 cases of Class Ⅲ,and 29 cases of Class Ⅳ according to the New York Heart Association(NYHA)functional classification.The patients were assignedto good prognosis group(n=62)and poor prognosis group(n=30).The general information and the levels of PⅢNP,IGF-1,and NTpro-BNP were compared between the two groups.Logistic regression analysis was used to identify the factors influencing the prognosis of elderly patients with CLHF,and a nomogram was constructed.Spearman correlation analysis was employed to examine the relationships between these indicators.Receiver operating characteristic(ROC)curves were constructed to analyze the predictive efficiency for the prognosis of elderly patients with CLHF.Results The diastolic pressure,systolic pressure,LVEDD,LVSDD,PⅢNP,and NTpro-BNP increased by the increase of NYHA classification,while the LVEF and IGF-1 decreased by the increase of NYHA classification(P<0.05).The levels of PⅢNP and NTpro-BNP in the good prognosis group were lower than those in the poor prognosis group,while IGF-1 in the good prognosis group was higher than that in the poor prognosis group(P<0.05).Logistic analysis indicated that PⅢNP,IGF-1,and NTpro-BNP were the factors affecting the prognosis of elderly patients with CLHF(P<0.05).Spearman correlation analysis revealed that PⅢNP and NTpro-BNP levels were positively correlated with NYHA functional classification,while IGF-1 was negatively correlated with NYHA functional classification(P<0.05).ROC curve results showed that the combined predictive value of PⅢNP,IGF-1,and NTpro-BNP was significantly superior to each parameter.Conclusion Serum levels of PⅢNP,IGF-1,and NTpro-BNP provide valuable assessment for the condition and prediction for prognosis of elderly CLHF patients.

Objective:To evaluate the left atrial function in patients with hypertrophic cardiomyopathy（HCM）combined with heart failure with preserved ejection fraction（HFpEF）using four-dimensional automated left atrial quantification（4D Auto LAQ）technology，and to investigate the independent factors affecting patients with HCM combined with HFpEF.Methods:One hundred HCM patients with left ventricular ejection fraction（LVEF）≥ 50% who were admitted to the First Affiliated Hospital of Zhengzhou University from September 2023 to March 2025 were prospectively selected. There were 50 cases in the HFpEF group and 50 cases in the non-HF group. The clinical data and conventional ultrasound parameters of HCM patients were collected. The 4D Auto LAQ technology was applied to obtain the four-dimensional volume and strain parameters of the left atrium，including the minimum left atrial volume（LAVmin），the maximum left atrial volume（LAVmax），the maximum left atrial volume index（LAVImax），the pre-atrial contraction volume（LAVpreA），the left atrial emptying volume（LAEV），the left atrial ejection fraction（LAEF），the longitudinal and circumferential strains in the left atrial reservoir period（LASr，LASr-c），the longitudinal and circumferential strains in the left atrial conduit period（LAScd，LAScd-c），the longitudinal and circumferential strains in the left atrial contraction period（LASct，LASct-c），and the minimum left atrial volume index（LAVImin）. The differences in the above parameters between the two groups were compared. Univariate and multivariate Logistic regression analyses were used to analyze the independent influencing factors in HCM patients with HFpEF. The intraclass correlation coefficient was used to test the repeatability of the 4D Auto LAQ parameters.Results:Compared with the non-HF group，LAVmin，LAVmax，LAVpreA，LAVImin，and LAVImax increased，while LAEF，LASr，LAScd，LASct，LASr-c，LAScd-c，and LASct-c decreased in the HFpEF group（all P<0.05）. Multivariate Logistic regression analysis showed that LASr was the strongest independent influencing factor in patients with HCM combined with HFpEF（ OR=0.255， P=0.003）. The consistency test showed that the intraclass correlation coefficients of each parameters of 4D Auto LAQ were all>0.7，the consistency was good. Conclusions:4D Auto LAQ technology can be used to evaluate left atrial function in patients with HCM combined with HFpEF，and LASr is the strongest independent influence factor in patients with HCM combined with HFpEF.

Objective:To investigate the efficacy of lightroom therapy on depressive mood and sleep problems in patients with depression, and the potential effects on physiological indices related to circadian rhythms.Methods:From October 2021 to July 2023, 54 patients with acute-phase depression hospitalized in the Mental Health Center of the First Hospital of Hebei Medical University were recruited. The participants were randomly assigned to either medication combined with the bright light therapy group (bright light group, n=36) or medication combined with the dim light therapy group (dim light group, n=18). Both groups received light therapy for 2 weeks, at 10 000 lx in the bright light group and 300 lx in the dim light group. Both groups received 30 minutes of light therapy from 7:30-8:00 a.m daily over two weeks, followed up for 1 week post-treatment. The Hamilton Depression Rating Scale (HAMD 17) was used to assess patients′ depressive symptoms, and the Pittsburgh Sleep Quality Index (PSQI) was used to assess patients′ sleep quality at baseline, at the end of every week. The 32-Item Hypomania Checklist (HCL-32) was used at the end of week 2 to assess the risk of manic switching after treatment. Daily measurements of body temperature, heart rate, and blood pressure were taken before and after light therapy, along with recording adverse events related to the therapy. Paired t- tests were used to compare changes in physiological indicators before and after treatment, and repeated measures ANOVA was applied to compare clinical symptom changes between the two groups. Results:Thirty-one and fifteen patients completed this study in the bright light and dim light groups, respectively, with no statistically significant difference in dropout rates( P>0.05). There were significant interaction effects between the time and group for HAMD 17 and PSQI score( F=5.51,4.11, both P<0.05). Both groups showed significant reductions in HAMD 17 and PSQI scores at baseline, week 1, week 2, and week 3 ( P<0.001). In the bright light group, body temperature increased significantly post-treatment on days 1-4, day 7, and day 12 (all P<0.05). Heart rate elevated on day 5 ( P<0.05).Systolic blood pressure decreased on days 4, 5, 11, and 12 compared to the pre-treatment baseline(all P<0.05). In the dim light group, systolic blood pressure increased on day 11 ( P<0.05). Diastolic blood pressure in the bright light group decreased on days 1, 5, and 6( P<0.05). No serious adverse events, vision loss, ocular structural changes occurred in either group. No hypomania or mania episodes were observed. The incidence of adverse events did not differ significantly ( P>0.05). Conclusion:Medication combined with indoor bright light is more effective than the combination of dim light for depressive symptoms and sleep problems in patients with depression. Patients receiving bright light also may exhibit a higher body temperature, accelerated heart rate, and reduced blood pressure.

Objective:To determine the diagnosis of microtia-associated syndrome through genetic testing.Methods:Peripheral venous blood samples were collected from members of a two-generation family with a syndrome associated with ear malformations (3 patients and 1 normal control). Pathogenic mutations were identified using whole exome sequencing analysis, Sanger sequencing validation, and bioinformatics analysis. Based on the genetic diagnosis and a review of the literatures, the patients′ clinical phenotypes were thoroughly evaluated to confirm the clinical diagnosis.Results:All three patients carried a novel heterozygous insertion mutation (c.1171_1172insGGCC: p.Pro391fs) in the paired box 1 ( PAX1) gene. This mutation showed genotype-phenotype co-segregation within the family and was predicted to be pathogenic. Consequently, the family was diagnosed with autosomal dominant otofaciocervical syndrome 2. The clinical phenotypes of the patients included not only ear malformations and conductive hearing loss but also branchial cleft fistula, preauricular fistula, bilateral facial asymmetry, spinal deformities, and short stature, which were major symptoms of otofaciocervical syndrome 2. Imaging also revealed previously unreported phenotypes, including parotid gland malformation and facial nerve dysplasia. Conclusion:The heterozygous insertion in PAX1 (c.1171_1172insGGCC: p.Pro391fs) found in this family causes otomandibular-cervical syndrome type 2 in an autosomal dominant manner, leading to congenital anomalies affecting external and middle ear, craniofacial region, and spine.
