ObjectiveTo investigate the relationship between the non-fasting triglyceride and glucose (TyG) index and hyperglycemia in pregnancy during the third trimester in high altitudes. MethodsThis study selected clinical and laboratory data of 774 Tibetan singleton pregnant women who delivered at Chaya People's Hospital of Qamdo city in Xizang autonomous region, from January 2023 to April 2025. The non-fasting TyG index was calculated from non-fasting triglyceride (TG) and random plasma glucose (PG). Based on the tertiles of the non-fasting TyG index values, the individuals were split into three groups (corresponding to non-fasting TyG index of 8.89 and 9.21, respectively). The baseline clinical characteristics, lipid levels and the occurrence of developing hyperglycemia in pregnancy were compared among the three groups. Statistical analyses were performed using ANOVA, Kruskal-Wallis H test, Chi-square test, or Fisher exact test and the relationship between the non-fasting TyG index and hyperglycemia in pregnancy were examined using multivariate logistic regression models and curve fitting. ResultsA total of 774 Tibetan singleton pregnant women were included, with a average age of 27.3 ± 6.1 years, a pre-delivery body mass index (Pre-BMI) of (25.2±2.3)kg/m2 , a proportion of 26.7% (207/774) primigravid women, the mean non-fasting TyG index was 9.1 ± 0.4。Thirty pregnant women were diagnosed with hyperglycemia in pregnancy, with a detection rate of 3.9% (30/774). Statistically significant differences in serum total cholesterol (TC), TG, low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels were identified when comparing different non-fasting TyG groups (all P values <0.05). Subsequent trend test analysis indicated that the levels of TC, TG, LDL-C, and PG gradually increased with elevated the non-fasting TyG index ( Ftrend TC=95.61, P<0.001; Ftrend TG=1 051.91, P<0.001; Ftrend LDL-C = 97.20, P < 0.001; Ftrend TG=195.20; P<0.001). After adjustment for maternal age, pre-delivery BMI, altitude, TC, LDL-C, and HDL-C, multivariate Logistic regression models revealed independent positive associations between non-fasting TyG index and hyperglycemia in pregnancy (Model 1: OR=2.72, 95% CI: 1.13-6.53, P=0.026; Model 2: OR=2.56, 95% CI: 1.01-6.50, P=0.048; Model 3: OR=2.72, 95% CI: 1.06-6.97, P=0.037; Model 4: OR=4.02, 95% CI: 1.42-11.40, P=0.009) and the incident of hyperglycemia in pregnancy showed an increasing tendency as increasing with the non-fasting TyG index, however, this association did not statistical significance (P trend >0.05). Curve fitting by restricted cubic splines (RCS) were used to assess linearity between non-fasting TyG and hyperglycemia in pregnancy, and there was a linear dose-response relationship between non-fasting TyG and hyperglycemia in pregnancy (P for non-linear = 0.515). ConclusionNon-fasting TyG index in the third trimester is a risk factor for hyperglycemia in pregnancy among the Tibetan singleton pregnant women at high altitudes and there was a possible linear dose-response relationship between the non-fasting TyG index and hyperglycemia in pregnancy.

Objective:To evaluate the effect of venous excess ultrasound score (VExUS Score) in the acute kidney injury(AKI) in Patients with sepsis, so as to reduce the risk of disease and improve the prognosis of patients.Methods:This experiment was a single-center prospective cohort study. Include septic patients with AKI who were admitted to the Department of Emergency Intensive Care Unit of the First Affiliated Hospital of Anhui Medical University from February 2022 to February 2023, Those with inadequate window, inferior vena cava (IVC) thrombus, age<18 years and known case of cirrhosis with portal hypertension were excluded from the study. Patients underwent ultrasound examination with serial determination till AKI resolved or patient is initiated on dialysis.Results:Totally 86 patients were enrolled for the study. The mean age was (60.43±15.48) with 50 (58.1%) males. Mean sequential organ failure assessment (SOFA) score was (6.23±1.87). 38 patients (44.2%) were in AKI stage 1, while 24 patients (27.9%) were in AKI stage 2 and stage 3 each. 52 patients (60.5%) had VExUS grade Ⅲ. Resolution of AKI injury showed significant correlation with improvement in VExUS grade ( p value 0.003). Similarly, there was significant association between changes in VExUS grade and fluid balance ( p value 0.005). There was no correlation between central venous pressure (CVP), left ventricular function, and right ventricular function with change in VExUS grade. Conclusions:The study shows a significant correlation between the VExUS Score and AKI staging, With improvement in kidney function, there is decline in the VExUS grade as well. Moreover VExUS Score might reliably demonstrate venous congestion and aid in the clinical decision to perform fluid removal.

The relationship between exercise and cardiac health has always been a hotspot in the fields of medicine and exercise science. Recently, with the in-depth study of the biological clock, people have gradually realized the close relationship between cardiac metabolic activity and circadian rhythms. The mammalian circadian system includes the central circadian clock and peripheral circadian clocks, the central circadian clock is the main clock system responsible for regulating the circadian rhythms in organisms, located in the suprachiasmatic nucleus (SCN) of the hypothalamus in mammals, which receives light signals from the retina and translates them into neural signals to regulate peripheral circadian clocks distributed throughout the body. Peripheral circadian clocks exist in various tissues and organs of organisms, coordinating with the central circadian clock to maintain the circadian rhythms of the organism. A series of clock genes regulate downstream clock-controlled genes through the transcriptional-translational feedback loop (TTFL), profoundly affecting the physiological activities of the heart, including cardiac contraction, relaxation, and metabolic processes. Factors such as sleep disorders, shift work, light pollution, and excessive use of electronic devices in modern lifestyles have led to widespread disruption of circadian rhythms, which are significantly correlated with increased cardiovascular disease incidence and mortality. Studies have found that dysregulation of the cardiac circadian clock can not only lead to myocardial lipid degeneration and weakened metabolic rhythms but also decrease myocardial glucose utilization, thereby increasing the risk of adverse cardiac events. Exercise, as a key zeitgeber, has been widely demonstrated to regulate the circadian clocks of peripheral organs such as skeletal muscle, kidneys, and liver. Additionally, exercise, as an important means to improve cardiovascular function, can effectively enhance cardiac metabolic function and resistance to stress stimuli, playing a significant role in promoting heart health. However, the specific mechanisms by which exercise affects the cardiac circadian clock and its related genes are currently unclear. Therefore, this review will focus on the relationship between the cardiac circadian clock and cardiac metabolic activity, summarize previous research to review the possible mechanisms of exercise-mediated regulation of cardiac metabolic activity on the cardiac circadian clock. The cardiac circadian clock plays an important role in maintaining cardiac metabolic activity and physiological functions. The loss of cardiac circadian clock genes Bmal1 and Clock can significantly reduce cardiac fatty acid and glucose utilization rates, increase myocardial lipotoxicity, weaken the circadian rhythm of myocardial triglyceride metabolism, and lead to abnormalities in the circadian clocks of other peripheral organs. Exercise, as a zeitgeber, can independently regulate the cardiac circadian clock apart from the central circadian clock. Additionally, exercise, as an important means to improve cardiovascular function, may regulate cardiac metabolic activity and the transcription of clock genes by activating the hypothalamic-pituitary-adrenal axis (HPA) and sympathetic-adrenal-medullary axis (SAM) and regulating energy metabolism, thereby maintaining the stability of the cardiac circadian clock and promoting heart health. Future research on the molecular mechanisms of exercise regulation of the cardiac circadian clock will help clarify the role and impact of clock genes in cardiac metabolism and physiological activities, providing new preventive and treatment strategies for shift workers, night owls, and patients with cardiovascular diseases. Therefore, future research should focus on (1) the mechanisms by which exercise regulates cardiac metabolic activity and the circadian clock, (2) the effects and mechanisms of exercise on the disruption of cardiac circadian clock induced by light-dark cycle disturbances, and (3) the effects of exercise on the metabolic activity and circadian rhythms of other peripheral organs regulated by the cardiac circadian clock.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Aim To explore the role and mechanism of nuclear receptor subfamily 1,group D,member 1(NR1D1)in the proliferation and migration of mouse adventitial fibroblasts(AFs). Methods Primary AFs isolated from C57BL/6J mice were cultured. Adenovirus carrying Nr1d1 gene was used to overexpress NR1D1 in AFs. The expression of β-catenin was restored by SKL2001. Proliferating cell nuclear antigen(Ki-67)immunofluorescence staining and CCK-8 staining were used to determine cell proliferation,and scratch test was used to determine cell migration. qPCR was used to determine the mRNA level of Nr1d1. Western blot was used to determine the protein levels of NR1D1 and β-catenin. To investigate the role of NR1D1 in intimal hyperplasia,20 male wild type C57BL/6J mice were randomly divided into sham group,carotid artery endothelial injury,sham+SR9009(NR1D1 agonist)group and carotid artery endothelial injury+SR9009(n=5 in each group). They were treated with DMSO or SR9009(100 mg·kg-1·d-1)via intraperitoneal injection for 14 days after operation,respectively. The degree of carotid intimal hyperplasia was measured by HE staining 28 days after operation. Results NR1D1 overexpression significantly reduced the percentage of Ki-67-positive cells(P<0.01),total cell number(P<0.01)and slowed down the rate of wound-healing(P<0.01). NR1D1 overexpression significantly inhibited the expression of β-catenin(P<0.05). After the expression of β-catenin was restored by SKL2001,the inhibitory effects of NR1D1 overexpression on the proliferation and migration of AFs were abolished(P<0.01). Enhanced activity of NR1D1 significantly ameliorated intimal hyperplasia after carotid endothelial injury(P<0.01). Conclusion NR1D1 may inhibit the proliferation and migration of AFs via suppressing the expression of β-catenin.

Background:
and Purpose To evaluate whether the thrombus enhancement sign (TES) can be used to differentiate embolic large vessel occlusion (LVO) from in situ intracranial atherosclerotic stenosis (ICAS)-related LVO in the anterior circulation of patients with acute ischemic stroke (AIS).
Methods:
Patients with LVO in the anterior circulation who underwent both non-contrast computed tomography (CT) and CT angiography and mechanical thrombectomy were retrospectively enrolled. Both embolic LVO (embo-LVO) and in situ ICAS-related LVO (ICAS-LVO) were confirmed by two neurointerventional radiologists after reviewing the medical and imaging data. TES was assessed to predict embo-LVO or ICAS-LVO. The associations between occlusion type and TES, along with clinical and interventional parameters, were investigated using logistic regression analysis and a receiver operating characteristic curve.
Results:
A total of 288 patients with AIS were included and divided into an embo-LVO group (n=235) and an ICAS-LVO group (n=53). TES was identified in 205 (71.2%) patients and was more frequently observed in those with embo-LVO, with a sensitivity of 83.8%, specificity of 84.9%, and area under the curve (AUC) of 0.844. Multivariate analysis showed that TES (odds ratio [OR], 22.2; 95% confidence interval [CI], 9.4–53.8; P<0.001) and atrial fibrillation (OR, 6.6; 95% CI, 2.8–15.8; P<0.001) were independent predictors of embolic occlusion. A predictive model that included both TES and atrial fibrillation yielded a higher diagnostic ability for embo-LVO, with an AUC of 0.899.
Conclusion
TES is an imaging marker with high predictive value for identifying embo- and ICAS-LVO in AIS and provides guidance for endovascular reperfusion therapy.

We investigated the impact and predictive value of bladder function in patients with benign prostatic hyperplasia (BPH) on the efficacy of transurethral prostatectomy. Symptomatic, imaging, and urodynamic data of patients who underwent transurethral prostatectomy at West China Hospital of Sichuan University (Chengdu, China) from July 2019 to December 2021 were collected. Follow-up data included the quality of life (QoL), International Prostate Symptom Score (IPSS), and IPSS storage and voiding (IPSS-s and IPSS-v). Moreover, urinary creatinine (Cr), nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and prostaglandin estradiol (PGE2) were measured in 30 patients with BPH and 30 healthy participants. Perioperative indicators were determined by subgroup analyses and receiver operating characteristic (ROC) curve analysis. Among the 313 patients with BPH included, patients with severe micturition problems had more improvements but higher micturition grades postoperatively than those with moderate symptoms. Similarly, good bladder sensation, compliance, and detrusor contractility (DC) were predictors of low postoperative IPSS and QoL. The urinary concentrations of BDNF/Cr, NGF/Cr, and PGE2/Cr in patients were significantly higher than those in healthy participants (all P < 0.001). After evaluation, only DC was significantly related to both urinary indicators and postoperative recovery of patients. Patients with good DC, as predicted by urinary indicators, had lower IPSS and IPSS-v than those with reduced DC at the 1st month postoperatively (both P < 0.05). In summary, patients with impaired bladder function had poor recovery. The combined levels of urinary BDNF/Cr, NGF/Cr, and PGE2/Cr in patients with BPH may be valid predictors of preoperative bladder function and postoperative recovery.
