Objective To explore the influencing factors of coronary artery lesion severity in patients with acute coronary syndrome (ACS). Methods Clinical data of ACS patients admitted to Zhongshan Hospital, Fudan University from December 2017 to December 2019 were consecutively collected. The modified Gensini score was used to assess the severity of coronary artery lesions. Univariate and multivariate linear regression analyses were performed to identify independent factors associated with coronary artery lesion severity. Results A total of 1 689 ACS patients were included, with an average age of (64.04±11.45) years; 1 353 (80.11%) were male, and the mean modified Gensini score was (8.12±4.03). Multivariate linear regression analysis revealed that sex (β＝0.97, P＝0.001), age (β＝0.03, P＝0.021), estimated glomerular filtration rate (eGFR; β＝－0.03, P＜0.001), low-density lipoprotein cholesterol (LDL-C; β＝0.58, P＜0.001), apolipoprotein A1 (Apo A1; β＝－1.28, P＝0.012), lipoprotein(a) [Lp(a); β＝0.001, P＝0.033], and glycated hemoglobin A_1C (HbA_1C; β＝0.45, P＜0.001) were independent influencing factors of the modified Gensini score. Conclusions Metabolic indicators, including Apo A1, LDL-C, HbA_1C, and Lp(a), may serve as risk factors for coronary artery lesion severity in ACS patients, with Apo A1 demonstrating the strongest impact.

Hepatic fibrosis is a key pathological process in the development of chronic liver disease to cirrhosis, and its core mechanism involves the activation of hepatic stellate cells(HSC) and abnormal deposition of extracellular matrix(ECM). Although existing treatments, such as antiviral drugs, can delay disease progression, they have the problem of single therapeutic targets and cannot reverse fibrosis. Accordingly, multidimensional intervention strategies are urgently needed. Recent studies have shown that circadian rhythm disorders aggravate hepatic fibrosis by regulating metabolism, immunity, and inflammation. Traditional Chinese medicine(TCM) plays a unique role in restoring the circadian clock via multi-target and holistic regulation. This paper establishes a three-dimensional network by systematically integrating biological clock, metabolism, and immunity for the first time to elucidate the scientific connotation of the theory of time-concerned treatment of TCM, and proposes a new strategy for the development of time-targeted compound prescriptions, providing innovative ideas for the treatment of hepatic fibrosis.

OBJECTIVES: To investigate the association between insulin resistance and uterine volume in girls with idiopathic central precocious puberty (ICPP). METHODS: A retrospective study was conducted involving 61 girls diagnosed with ICPP who visited the pediatric growth and development clinic of the Third Affiliated Hospital of Zhengzhou University between January 2022 and September 2024, designated as the ICPP group, and 61 normally developing girls as the control group. The differences in insulin resistance index (homeostasis model assessment of insulin resistance, HOMA-IR), uterine volume, and other indicators between the two groups were compared, and the relationship between insulin resistance and uterine volume in these girls was analyzed. RESULTS: The uterine volume and HOMA-IR level in the ICPP group were significantly higher than those in the control group (P<0.05). Correlation analysis revealed that there was a positive correlation between HOMA-IR level and uterine volume in the ICPP group (r_s=0.643, P<0.001). Multiple linear regression analysis indicated that as HOMA-IR increased,uterine volume in the girls tended to increase (P<0.05). CONCLUSIONS There is an association between insulin resistance and uterine volume in girls with ICPP, and as HOMA-IR increases, uterine volume in the girls also increases.

OBJECTIVE: Hepatocellular carcinoma (HCC) is sensitive to ferroptosis, a new form of programmed cell death that occurs in most tumor types. However, the mechanism through which ferroptosis modulates HCC remains unclear. This study aimed to investigate the oncogenic role and prognostic value of FANCD2 and provide novel insights into the prognostic assessment and prediction of immunotherapy. METHODS: Using clinicopathological parameters and bioinformatic techniques, we comprehensively examined the expression of FANCD2 macroscopically and microcosmically. We conducted univariate and multivariate Cox regression analyses to identify the prognostic value of FANCD2 in HCC and elucidated the detailed molecular mechanisms underlying the involvement of FANCD2 in oncogenesis by promoting iron-related death. RESULTS: FANCD2 was significantly upregulated in digestive system cancers with abundant immune infiltration. As an independent risk factor for HCC, a high FANCD2 expression level was associated with poor clinical outcomes and response to immune checkpoint blockade. Gene set enrichment analysis revealed that FANCD2 was mainly involved in the cell cycle and CYP450 metabolism. CONCLUSION To the best of our knowledge, this is the first study to comprehensively elucidate the oncogenic role of FANCD2. FANCD2 has a tumor-promoting aspect in the digestive system and acts as an independent risk factor in HCC; hence, it has recognized value for predicting tumor aggressiveness and prognosis and may be a potential biomarker for poor responsiveness to immunotherapy.

Objective To investigate the effects of advanced maternal age(AMA)on synaptic pruning of the hippocampus of offspring rats.Methods Offspring of 3-month-old SD female rats and 3-month-old SD male rats were designated as the appropriate age group(Ctl group),while offspring of 12-month-old SD female rats and 3-month-old SD male rats were assigned to AMA group.Hippocampal tissues from both groups(n=3 per group at each time point)were subjected to Golgi staining on postnatal days(P)7,28,and 60.Dendritic complexity,spine density(DS),and morphology of immature brain neurons at different age stages were compared between the two groups.Results Compared with Ctl group,the dendritic length of AMA group on P7,P28,and P60 was significantly shortened,and the average number of intersections between dendrites and concentric circles on P28 and P60 was also significantly decreased(P<0.05).Compared with Ctl group,the dendritic spine density of AMA group was significantly decreased on P7,P28,and P60.Notably,the density of thin-shaped dendritic spines in AMA group was increased on P7,whereas the densities of stubby-shaped and mushroom-shaped dendritic spines were decreased(P<0.05).On P28 in AMA group,the densities of thin-shaped and mushroom-shaped dendritic spines were significantly increased compared with Ctl group,while the density of stubby-shaped dendritic spines was significantly decreased(P<0.05).The densities of stubby-shaped and mushroom-shaped dendritic spine were markedly lower in AMA group on P60 than those in Ctl group(P<0.05).Conclusions During postnatal brain development periods,there were abnormalities in synaptic pruning in the hippocampal region of the offspring of the AMA,which manifested as reduced dendritic complexity,decreased dendritic spine density,and disorganized dendritic spine morphology.It could be one of the key mechanisms underlying brain dysfunction in the offspring of AMA.

Objective To develop an erythrocyte-based delivery system for butyrylcholinesterase(BChE)that is capable of prophylaxis against organophosphorus nerve agents.Methods Recombinant BChE was produced and analyzed for oligomerization via polyacrylamide gel electrophoresis(PAGE)and Western blotting.A modified hypotonic preswelling method was employed to prepare BChE-loaded erythrocytes.The drug loading capacity and encapsulation efficiency were quantified using enzyme-linked immunosorbent assay(ELISA).Catalytic activity was assessed in vitro with an activity detection kit.The system was characterized via scanning electron microscopy(SEM),flow cytometry and a hematology analyzer.Results Recombinant BChE predominantly existed as dimers(85％dimer,15％monomer).The optimized volume ratio of erythrocytes to hypotonic solution was determined as 1:7.Compared with native and empty erythrocytes,BChE-loaded erythrocytes exhibited significantly higher catalytic activity(P＜0.001).The mean corpuscular volume of BChE-loaded erythrocytes increased(P＜0.001),while the mean content of corpuscular hemoglobin and hemoglobin in erythrocytes per 100 mL decreased(P＜0.001).SEM revealed no morphological differences(biconcave disc shape).Hypotonic preswelling moderately increased erythrocyte apoptosis(P＜0.001),but no statistical difference was observed between BChE-loaded and hypotonic-treated erythrocytes(P＞0.05).CD47 expression remained unchanged compared to native erythrocytes(P＞0.05).Conclusion The modified hypotonic preswelling method can generate BChE-loaded erythrocytes that retain the characteristics of native erythrocytes while conferring catalytic activity,offering a novel strategy for clinical intervention against organophosphorus poisoning.

Objective To investigate the effect of Tan Ⅰ on SA-AKI in rats by mediating Wnt/β-catenin signaling pathway.Methods Sprague-Dawley rats were randomly divided into the following groups(n=8 per group,including 2 reserve animals per group):Sham,SA-AKI,SA-AKI+5 mg/kg Tan I,SA-AKI+10 mg/kg Tan I,SA-AKI+15 mg/kg Tan I(SA-AKI+Tan I),SA-AKI+salinomycin sodium(SS,Wnt signal inhibitor,SA-AKI+SS),SA-AKI+SS+Tan I,SA-AKI+laduviglusib(LG,Wnt signal activator,SA-AKI+LG),and SA-AKI+LG+Tan I.Rat SA-AKI model was induced by cecal ligation and puncture(CLP),with Tan I,SS,and LG administered via intraperitoneal injection.Hematoxylin-eosin and TUNEL staining were used to observe renal tissue pathological damage.Enzyme-linked immunosorbent assay was used to detect serum concentrations of neutrophil gelatinase-associated lipocalin(NGAL),IL-1β,IL-8,IL-6,and TNF-α.Creatinine(Cre)and blood urea nitrogen(BUN)kit were used to detect serum Cre and BUN concentrations.Western blot and immunofluorescence staining were used to detect the expression and fluorescence intensity of Wnt1,GSK3β,and β-catenin.Results Administration of Tan I at doses of 10 mg/kg and 15 mg/kg significantly attenuated renal injury in rats with SA-AKI(P<0.05),suppressed the levels of SA-AKI biomarkers NGAL,Cre,and BUN and pro-inflammatory cytokines(P<0.05),reduced apoptosis,and downregulated Wnt1 and GSK3β while upregulating β-catenin expression(P<0.05).Although Tan I at 5 mg/kg exhibited a modest protective effect against SA-AKI in rats,no statistically significant difference was observed compared to the sham group(P>0.05).SS weakened CLP-induced kidney injury and the production of inflammatory cytokines in rats(P<0.05),and LG further aggravated CLP-induced kidney injury in rats(P<0.05).Tan Ⅰ reversed the promoting effect of LG on kidney injury in SA-AKI rats(P<0.05).Conclusion Tan Ⅰ provides a protective effect on CLP-induced SA-AKI rat by inhibiting Wnt/β-catenin signaling pathway.

Background::Risk assessment and treatment stratification for three-vessel coronary disease (TVD) remain challenging. This study aimed to investigate the prognostic value of left atrial volume index (LAVI) with the Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score II, and its association with the long-term prognosis after three strategies (percutaneous coronary intervention [PCI], coronary artery bypass grafting [CABG], and medical therapy [MT]) in patients with TVD.Methods::This study was a post hoc analysis of a large, prospective cohort of patients with TVD in China, that aimed to determine the long-term outcomes after PCI, CABG, or optimal MT alone. A total of 8943 patients with TVD were consecutively enrolled between 2004 and 2011 at Fuwai Hospital. A total of 7818 patients with available baseline LAVI data were included in the study. Baseline, procedural, and follow-up data were collected. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), which was a composite of all-cause death, myocardial infarction (MI), and stroke. Secondary endpoints included all-cause death, cardiac death, MI, revascularization, and stroke. Long-term outcomes were evaluated among LAVI quartile groups. Results::During a median follow-up of 6.6 years, a higher LAVI was strongly associated with increased risk of MACCE (Q3: hazard ratio [HR] 1.20, 95% confidence interval [CI] 1.06-1.37, P = 0.005; Q4: HR 1.85, 95%CI 1.64-2.09, P <0.001), all-cause death (Q3: HR 1.41, 95% CI 1.17-1.69, P <0.001; Q4: HR 2.54, 95%CI 2.16-3.00, P <0.001), and cardiac death (Q3: HR 1.81, 95% CI 1.39-2.37, P <0.001; Q4: HR 3.47, 95%CI 2.71-4.43, P <0.001). Moreover, LAVI significantly improved discrimination and reclassification of the SYNTAX score II. Notably, there was a significant interaction between LAVI quartiles and treatment strategies for MACCE. CABG was associated with lower risk of MACCE than MT alone, regardless of LAVI quartiles. Among patients in the fourth quartile, PCI was associated with significantly increased risk of cardiac death compared with CABG (HR: 5.25, 95% CI: 1.97-14.03, P = 0.001). Conclusions::LAVI is a potential index for risk stratification and therapeutic decision-making in patients with three-vessel coronary disease. CABG is associated with improved long-term outcomes compared with MT alone, regardless of LAVI quartiles. When LAVI is severely elevated, PCI is associated with higher risk of cardiac death than CABG.

Objective To explore the distribution patterns of tongue and pulse manifestations and traditional Chinese medicine(TCM)syndrome elements in ischemic stroke(IS)patients of different genders and ages,thus to provide approaches for the prevention and treatment of stroke with TCM.Methods The criteria of six syndrome elements in Diagnostic Scale of Syndrome Elements in Ischemic Stroke were used for the comprehensive identification of syndrome elements in 5 254 cases of inpatients confirmed as IS at the first visit in Shenzhen Traditional Chinese Medicine Hospital from 2017 to 2023.Moreover,the tongue proper,tongue coating,and whose pulse manifestations ranking in the top five in terms of the frequency of occurrence were collected for comparison and analysis.Results(1)For the distribution of TCM syndrome elements in 5 254 cases of IS patients,phlegm-dampness syndrome was the most common syndrome type(3 544 cases,67.5%),and then came qi deficiency syndrome(653 cases,12.4%)and yin deficiency syndrome(453 cases,8.6%).There were statistically significant differences in the distribution of phlegm-dampness syndrome,internal heat syndrome,and yin deficiency syndrome between the male and the female(P＜0.01).And the distribution of phlegm-dampness syndrome,qi deficiency syndrome,internal wind syndrome,and internal heat syndrome in the youth differed from that in the middle-aged and elderly(P＜0.01).(2)The tongue and pulse manifestations in IS patients with the leading six detection rates which ranked in descending order of frequency of occurrence were as follows:dull tongue(1 993 cases,37.9%),dark red tongue(1 907 cases,36.3%),thin and white coating(1 885 cases,35.9%),wiry and slippery pulse(1 714 cases,32.6%),white and greasy coating(1 679 cases,32.0%),and wiry and thready pulse(1 609 cases,30.6%).The detection rates of tongue and pulse manifestations such as light red tongue,thin and white coating in the youth group were significantly higher than those in the middle-aged and elderly group,and the detection rates of dark red tongue,and tooth-marked tongue in the middle-aged and elderly group were significantly higher than those in the youth group,the differences all being statistically significant(P＜0.05).The female patients had higher detection rates of dull tongue,thin and white coating,thin and yellow coating,wiry and thready pulse,and deep and thready pulse than male patients,while the male patients had higher detection rates of dark red tongue,red tongue,white and greasy coating,yellow and thick-greasy coating,white and thick-greasy coating,wiry and slippery pulse,and slippery pulse than the females,and the differences were all statistically significant(P＜0.05 or P＜0.01).Higher detection rate of thin and white coating was shown in the youth female than that in the youth male,while higher detection rate of wiry and slippery pulse was shown in the youth male than that in the youth female,and the differences were all statistically significant(P＜0.05 or P＜0.01).The middle-aged and elderly female patients had higher detection rates of dull tongue,thin and white coating,wiry and thready pulse,and deep and thready pulse than the middle-aged and elderly male patients,while the middle-aged and elderly male patients had higher detection rates of dark red tongue,red tongue,white and greasy coating,white and thick-greasy coating,yellow and thick-greasy coating,wiry and slippery pulse,and slippery pulse than the middle-aged and elderly female patients,the differences being all statistically significant(P＜0.05 or P＜0.01).Conclusion Phlegm-dampness syndrome,qi deficiency syndrome,and yin deficiency syndrome exert a significant effect on IS,and phlegm-dampness syndrome is the most common syndrome type.Factors such as gender and age have influences on the distribution of TCM syndrome in patients with IS.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.
