Objective To explore the potential clinical value of the ratio of glycated albumin to albumin(GA/ALB)in the occurrence of heart failure(HF)among patients with coronary atherosclerotic heart disease(CHD).Methods A total of 337 CHD patients admitted to the Department of Cardiology in Shanxi Provincial People's Hospital from July 2023 to June 2024 were selected in this study.CHD patients were divided into HF group and non-HF group based on whether they progressed to HF.The clinical data and laboratory parame-ters of the two groups were compared.Restricted cubic spline curve was used to analyze the relationship be-tween GA/ALB levels and the risk of HF in CHD patients.Receiver operating characteristic curve was applied to evaluate the diagnostic efficacy of GA/ALB,GA,platelet to lymphocyte ratio(PLR),and monocyte to lym-phocyte ratio(MLR)in CHD patients with the occurrence of HF.Logistic regression was used to explore the relationship between serum GA/ALB levels and the risk of CHD patients occurrence of HF,and to analyze the degree of influence and stability of subgroup variables on results.Results There were statistically significant differences in GA/ALB,GA,PLR,MLR,and other indicators between the HF group and the non-HF group in CHD patients(P＜0.05).A non-linear relationship was observed between GA/ALB levels and the risk of HF in CHD patients.When the value of GA/ALB multiplied by 10 was less than 5.751,the risk of HF in CHD pa-tients increased with the increase of GA/ALB levels(P＜0.001).GA/ALB was an effective predictor for HF occurrence in CHD patients.Multivariable Logistic regression model showed that GA/ALB was an independ-ent risk factor for CHD patients with occurrence of HF.Subgroup analysis also confirmed the stability of GA/ALB in predicting the occurrence of HF in CHD patients.Conclusion GA/ALB is an independent risk factor for the occurrence of HF in CHD patients,and monitoring GA/ALB levels provides predictive value for the oc-currence of HF in these patients.

Objective To investigate the safety and efficacy of super-selective arterial embolization in the treatment of abdominal wall hematoma.Methods The clinical data of 11 patients with abdominal wall hematoma,who were admitted to the Northern Jiangsu People's Hospital of China from January 2018 to December 2023,were retrospectively analyzed.All patients received angiography together with super-selective arterial embolization.The effectiveness of embolization treatment was evaluated by the technical success rate and therapeutic effect,and the safety was evaluated by the incidence of complication.Results The median age of the 11 patients was 70 years,91％were female,with a body mass index(BMI)of 25.1 kg/m2,subcutaneous fat thickness of 2.8 cm,and international normalized ratio(INR)of 1.12.DSA showed that 8 patients(72％)had active bleeding signs,3 patients(28％)had no active bleeding signs.Under DSA,a total of 18 responsible vessels,including 6 lumbar arteries(33.3％),5 deep circumflex iliac arteries(27.7％),5 inferior epigastric arteries(27.7％)and 2 iliolumbar arteries(11.3％),were identified and were treated with embolization.The median time spent for operation was 80 minutes.The technical success rate was 100％and the clinical effective rate was 91％.No operation-related major complications occurred,and the median hospital stay was 6 days.Conclusion For the abdominal wall hematoma in aged,obesity patients with underlying diseases,super-selective arterial embolization is a therapeutic method with high technical success rate,high clinical effective rate and satisfactory clinical safety.

Chemotherapy-induced complications, particularly lethal cardiovascular diseases, pose significant challenges for cancer survivors. The intertwined adverse effects, brought by cancer and its complication, further complicate anticancer therapy and lead to diminished clinical outcomes. Simple supplementation of cardioprotective agents falls short in addressing these challenges. Developing bi-functional co-therapy agents provided another potential solution to consolidate the chemotherapy and reduce cardiac events simultaneously. Drug repurposing was naturally endowed with co-therapeutic potential of two indications, implying a unique chance in the development of bi-functional agents. Herein, we further proposed a novel "trilogy of drug repurposing" strategy that comprises function-based, target-focused, and scaffold-driven repurposing approaches, aiming to systematically elucidate the advantages of repurposed drugs in rationally developing bi-functional agent. Through function-based repurposing, a cardioprotective agent, carvedilol (CAR), was identified as a potential neddylation inhibitor to suppress lung cancer growth. Employing target-focused SAR studies and scaffold-driven drug design, we synthesized 44 CAR derivatives to achieve a balance between anticancer and cardioprotection. Remarkably, optimal derivative 43 displayed promising bi-functional effects, especially in various self-established heart failure mice models with and without tumor-bearing. Collectively, the present study validated the practicability of the "trilogy of drug repurposing" strategy in the development of bi-functional co-therapy agents.

ObjectiveTo explore the clinical features and causative genes of short stature children with unknown etiology， providing evidence for precise clinical diagnosis and treatment. MethodsThe study recruited children with suspected but undiagnosed short stature from the pediatric endocrinology department in our hospital between January 2018 and August 2022. A retrospective analysis was performed on the clinical manifestations， laboratory test and whole exome sequencing （WES） results. Causative genes were classified and analyzed according to different pathogenic mechanisms. ResultsA total of 48 children （30 boys and 18 girls） were enrolled， aged 7.73 ± 3.97 years， with a height standard deviation score （ HtSDS） of -3.63 ± 1.67. Of the patients， 33 （68.8%） suffered from facial anomalies， 31 （64.6%） from skeletal abnormalities， 26 ［54.2%， 61.5% of whom born small for gestational age （SGA）］ from perinatal abnormalities， 24 ［50.0%， 87.5% of whom with growth hormone （GH） peak concentration below normal］ from endocrine disorders and 21（43.8%） had a family history of short stature. Laboratory tests showed that GH peak concentration following stimulation test was （9.72 ± 7.25） ng/mL， IGF-1 standard deviation score was -0.82 ± 1.42， the difference between bone age and chronological age was -0.93 ± 1.39 years. Of the 25 cases with mutant genes found by WES， 14 （56.0%） had pathogenic mutation， 6 （24.0%） likely pathogenic mutation， and 5 （20.0%） mutation of uncertain significance. Pathogenic and likely pathogenic variants were identified in 14 genes， including 10 affecting intracellular signaling pathways （PTPN11， RAF1， RIT1， ARID1B， ANKRD11， CSNK2A1， SRCAP， CUL7， SMAD4 and FAM111A） and 4 affecting extracellular matrix （ECM） components or functions （ACAN， FBN1， COL10A1 and COMP）. ConclusionsA rare monogenic disease should be considered as the possible etiology for children with severe short stature accompanied by facial anomalies， disproportionate body types， skeletal abnormalities， SGA， GH peak concentration below normal and a family history of short stature. WES played an important role in identifying the monogenic causes of short stature. This study indicated that affecting growth plate cartilage formation through intracellular signaling pathways and ECM components or functions was the main mechanism of causative genes leading to severe short stature in children. Further research may help discover and study new pathogenic variants and gene functions.

Objective:To investigate the effect of modified percutaneous closure in the treatment of ventricular septal rupture.Methods:This study is a retrospective cohort study. Forty-four patients with ventricular septal rupture who underwent percutaneous closure at the Fuwai Central China Cardiovascular Hospital from December 2017 to October 2023 were included. According to the closure method, patients were divided into the modified group (11 cases) and the traditional group (33 cases). Surgical success was defined as successful placement of the occluder. The operation time, X-ray intake, sheath bending rate, incidence of ventricular fibrillation and pericardial tamponade, and postoperative residual shunt were compared between the two groups.Results:The age of the patients was (75.0±5.7) years, with 20 (45%) males. There were 3 cases of operation failure in the traditional group, while all patients in the modified group were successfully occluded. The procedure time in the modified group was shorter than that in the traditional group (40 (35, 45) min vs. 60 (50, 65)min, P<0.001); X-ray dose intake was lower ((442.43±73.26)mGy vs. (784.45±247.78)mGy, P<0.001). There was no occurrence of sheath bending in the modified group, while the incidence of sheath bending in the traditional surgery group was 46% (15/33), and the difference was statistically significant ( P=0.017). Intraoperative ventricular fibrillation and pericardial tamponade occurred in 7 cases (21%) and 2 cases (6%) in the traditional group respectively, while none occurred in the modified group, but the differences between the groups were not statistically significant (both P>0.05). There was no significant difference in residual shunt between the two groups (3.6 (2.5, 4.3) mm vs. 4.0 (3.5, 4.5) mm, P=0.506). Conclusion:The procedure of modified ventricular septal rupture closure is more simplified, with a lower incidence ofventricular fibrillation and pericardial tamponade.

Objective To explore the effect of glioma stem cells with high expression of protein tyrosin phosphatase receptor type Z1 (PTPRZ1 )on the phenotypic polarization and phagocytosis of tumor-associated macrophages and its regulatory mechanism.Methods GSCs and non-stem tumor cells (NSTCs) were screened out from human glioblastoma (GBM) specimens using flow cytometry,and the PTPRZ1 expression in paired GSCs and NSTCs were detected.Human peripheral blood mononuclear cells (PBMC)-derived CD14+monocytes were exposed to the conditioned medium from glioma cells or recombinant chemokine C-C motif ligand 20 (CCL20)for TAM polarization.Stable PTPRZ1 knockout GSCs (PTPRZ1-KO GSCs) were constructed using CRISPR/Cas9. TAM phagocytosis to GSCs,NSTCs,PTPRZ1-Control GSCs (PTPRZ1-Ctrl GSCs)and PTPRZ1-KO GSCs and the expression of immunosuppressive phenotype (M2) polarization marker CD163 were examined using flow cytometry.Differentially expressed genes (DEGs ) between paired GSCs and NSTCs were determined using a bulk RNA-sequencing dataset (GSE54791 )from Gene Expression Omnibus (GEO).A gene set informing worse outcome of patients with GBM was generated using The Cancer Genome Atlas (TCGA)-GBM cohort.By intersecting the aforementioned gene set with the gene set that encodes for human membrance proteins,the PTPRZ1 gene is obtained.Gene set enrichment analysis (GSEA)was used for pathway enrichment analysis to compare the differentially regulated pathways between GBMs with high or low PTPRZ1 expression.Bulk RNA sequencing,qRT-PCR and Western blotting were used to identify the DEGs between PTPRZ1-KO GSCs and PTPRZ1-Ctrl GSCs.Results GSCs were more capable of escaping from TAM phagocytosis than NSTCs (P<0.05 )and had specifically up-regulated PTPRZ1 expression.PTPRZ1-KO significantly suppressed GSCs escaping from TAM phagocytosis (P<0.01 ). GBMs with high PTPRZ1 expression showed significant inhibition of pathways mediating phagocytosis (P<0.05).The expression of CCL20 as a M2 TAM polarization chemokine was significantly down-regulated in PTPRZ1-KO GSCs (P<0.05 ).Treatment with recombinant CCL20 up-regulated the expression of CD163 as a M2 TAM marker in TAM.Conclusion PTPRZ1+GSCs mediate M2 TAM polarization and inhibit TAM phagocytosis,which may be related to the up-regulation of CCL20 in PTPRZ1+GSCs.

Objective:To summarize long-term clinical follow-up results of segment instability between the upper instrumented vertebra (UIV) and the adjacent upper vertebra (UIV+1) and to establish the optimal timing for surgery for UIV+1.Methods:A retrospective analysis was conducted on 265 patients with lumbar degenerative diseases who underwent transforaminal lumbar interbody fusion (TLIF) surgery at the Department of Spinal Surgery, Zhongda Hospital, from January 2014 to December 2018. The cohort included 119 male and 146 female patients, with an average age of 64.93 years (range: 32-86 years). Preoperative dynamic imaging measured sagittal angulation (SA) and sagittal translation (ST) of the UIV+1/UIV segment. Patients with SA>10° or ST>2 mm were categorized into the unstable group, further divided into the unstable non-fusion group and the unstable fusion group based on whether UIV+1 expansion fusion was performed. The remaining patients were classified into the stable group. Imaging indicators, Visual Analogue Scale (VAS) scores, Oswestry disability index (ODI) scores, and Japanese Orthopaedic Association (JOA) scores were compared among the groups, with JOA improvement rates calculated to assess clinical efficacy. Pearson correlation coefficient analysis was employed to examine correlations between preoperative imaging indicators and final follow-up JOA improvement rates. Receiver Operating Characteristic (ROC) curves and the maximum Youden index were utilized to determine thresholds for preoperative SA and ST.Results:The follow-up duration for all patients was 73.53±12.92 months (range: 61-108 months). The stable group (124 cases) included 61 males and 63 females, aged 64.31±9.83 years (range: 44-82 years). The unstable non-fusion group (59 cases) included 22 males and 37 females, aged 65.76±11.01 years (range: 32-86 years). The unstable fusion group (82 cases) included 36 males and 46 females, aged 65.26±8.68 years (range: 47-80 years). At the last follow-up, the unstable non-fusion group exhibited ΔSA 0.90°±1.97° and ΔST 0.77±1.27 mm, both significantly higher than the stable group's ΔSA 0.25°±1.57° and ΔST 0.34±0.34 mm ( t=3.564, P<0.001; t=2.311, P=0.022). Clinical improvements were lower in the unstable non-fusion group compared to the other two groups: VAS (2.28±0.83), ODI (5.91%±3.46%), JOA (24.11±1.78), with a JOA improvement rate of 60%. The stable group showed VAS (1.51±0.69), ODI (3.71%±1.75%), JOA (27.33±1.91), with a JOA improvement rate of 83%. The unstable fusion group had VAS (1.46±0.83), ODI (3.46%±1.81%), JOA (26.48±1.66), with a JOA improvement rate of 78%. These differences were statistically significant ( F=32.117, P<0.001; F=24.827, P<0.001; F=92.658, P<0.001; F=93.341, P<0.001). The JOA improvement rate was negatively correlated with preoperative SA ( r=-0.363, P<0.001) to a low extent, and with preoperative ST ( r=-0.596, P<0.001) to a moderate extent. ROC curve analysis determined the preoperative SA threshold as 11.5° and the preoperative ST threshold as 1.85 mm. Conclusion:Pre-existing instability of the responsible segment UIV and UIV+1 (SA>10° or ST>2 mm) may worsen during long-term follow-up after TLIF. When preoperative SA exceeds 11.5° and ST exceeds 1.85 mm between UIV and UIV+1, performing an extended fusion involving UIV+1 can ensure surgical efficacy over long-term follow-up.

With an aging population, the incidence of osteoporotic vertebral fractures (OVFs) is on the rise, posing new challenges for developing personalized treatment strategies. For patients who do not respond to conservative treatment, percutaneous vertebroplasty or percutaneous kyphoplasty (PVP/PKP) remains the preferred surgical option due to its minimal invasiveness and rapid recovery time. However, progressive local kyphosis (PLK) is one of the most severe complications following PVP/PKP, with an incidence rate of 1.5%-25.8%. PLK often presents with recurring thoracic and lower back pain, and in severe cases, spinal stenosis, causing symptoms like numbness and pain in the lower limbs. The severity of PLK varies, and treatments can range from conservative management and bone cement reinforcement to internal fixation or osteotomy. Current studies suggest that re-fracture of the affected vertebra, intervertebral disc degeneration, and osteonecrosis may be underlying mechanisms. These conditions shift the axial load forward, promoting postoperative PLK, which tends to progress over time. Postoperative PLK is closely associated with patient characteristics, fracture details, surgical factors, and post-surgery osteoporosis management. 1) The severity of osteoporosis, as indicated by the T-score from bone mineral density testing, can help predict postoperative PLK. While factors like age and gender influence osteoporosis severity, no direct relationship has been established between these factors and PLK. 2) Thoracolumbar fractures, old nonunion fractures, endplate fractures, or severe preoperative compression changes with kyphosis can increase PLK risk. Surgical factors, including the use of balloons or implants and the distribution of bone cement, also play a role. Personalized treatment plans should be developed based on the patient's general condition and imaging results to ensure adequate bone cement diffusion, as enhanced integration can reduce PLK risk. 3) Postoperative anti-osteoporosis therapy is also crucial; long-term therapy, particularly with teriparatide, can prevent PLK. Recognizing the related risk factors and establishing predictive models can help clinicians tailor treatments. Machine learning models, utilizing big data, are particularly adept at handling complex interrelated risk factors and may provide a powerful tool for personalized treatment in the future.

Objective:To investigate the efficacy and safety of oral testosterone therapy in individuals diagnosed with androgen insensitivity syndrome (AIS).Methods:A self-controlled study design was utilized, focusing on individuals with AIS who were genetically diagnosed at the Department of Endocrinology, Genetics, and Metabolism of Beijing Children′s Hospital between 2009 and 2021. These patients underwent treatment involving the administration of testosterone. The primary observed indexes include the measurement of penis length, which should meet the minimal surgical standard (penis length≥2.5 cm) or greater than or equal to -2.5 s (lower limit of normal). Secondary observed indexes include penile length standard deviation score (PL-SDS), an increase in penis longitude (ΔPL), medication dosage, the course of therapy, and safety indicators, among others. There were 4 courses of treatment. After each course, patients were evaluated to determine whether termination of treatment was appropriate. Patients who exhibited inadequate post-treatment penile length growth were advised to continue with further treatment. The statistical methodology included t-test, and a Wilcoxon rank sum test to describe efficacy and safety. The patients were followed up until 2023. Results:The study comprised a total of 51 individuals with AIS, comprising 33 males and 18 females (gender of registered permanent residence). Among these patients, 10 were diagnosed with complete androgen insensitivity syndrome (CAIS) and 41 were diagnosed with partial androgen insensitive syndrome (PAIS). There were 2 children with CAIS were diagnosed by doctors and prescribed testosterone undecanoate, but the children did not really take medicine.The penile length of CAIS patients could not be measured (penile length<0.5 cm) before and after treatment. For PAIS patients, baseline penile length and PL-SDS were (2.3±0.6) cm and -3.7±1.3, respectively. The measurements for penile length and PL-SDS after each treatment course were recorded as follows: (2.7±0.8), (2.8±0.6), (2.6±0.4), (2.6±0.4) cm and -2.8±1.6, 2.5±1.6, 2.9±1.2, -3.2±0.9, respectively. Both penile length and PL-SDS interventions showed statistically significant gains when compared to the baseline performance of the 4 courses ( t=4.05、3.56、2.55、2.23 and 3.88、3.50、2.50、2.19, all P<0.05). Before treatment, 13 PAIS patients (32%) reached 2.5 cm and seven (17%) reached greater than or equal to -2.5 s. Following the initial, subsequent, third, and fourth therapeutic interventions, 18 cases (44%), 24 cases (59%), 25 cases (61%), and 26 cases (63%) reached 2.5 cm, respectively. Additionally, A total of 12 cases (29%), 15 cases (37%), 20 cases (49%), and 21 cases (51%), respectively, were found to reach greater than or equal to -2.5 s. The study involved the longitudinal monitoring of patients with the highest recorded age being 13.7 years. The weight, height, body mass index, bone age/age, cholesterol, hemoglobin and so on were all within the normal range and the difference were not statistically significant (all P>0.05). All 49 patients were no abnormalities in blood electrolyte, liver and kidney function and thyroid function and no changes in precocious puberty, pubic hair growth, aggressive behavior, vulvar skin darkening, diarrhea or other conditions. Conclusions:Testosterone undecanote in children with CAIS was no effective. The initial course of treatment for patients with PAIS demonstrates observable enhancements in penile length and PL-SDS. For patients with inadequate penile length growth, continued treatment in subsequent courses (such as the second, third, and fourth courses) is recommended toenhance outcomes gradually. Testosterone undecanoate was safe and effective for the majority of individuals with PAIS patients, with few adverse effects and good treatment tolerance.
