T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

Objective:To analyze the validity of an enhanced nutrition management model for all pregnant women in reducing the incidence of macrosomia.Methods:This retrospective cohort study utilized data from the Beijing Birth Cohort database established by Beijing Obstetrics and Gynecology Hospital, Capital Medical University. A total of 73 193 pregnant women who underwent regular prenatal examinations and delivered at the hospital between January 2018 and December 2023 were consecutively included. From 2018 to 2020, all participants received nutrition education, and high-risk pregnancies predisposed to macrosomia were referred to nutrition clinics for further follow-up. From 2021 to 2023, obstetricians participated in nutritional assessments and gestational weight gain guidance, with repeated nutrition evaluations and education provided during early, mid, and late pregnancy. A multidisciplinary team (obstetrics and nutrition departments) collaborated to implement an enhanced nutrition management model for all pregnant women. General data, parity, gestational age at delivery, neonatal birth weight, and clinical information were collected. Annual incidences of macrosomia and low birth weight were calculated. Chi-square tests and variance analysis were used to analyzed yearly changes in macrosomia rates and evaluate the impact of the two-phase management strategies on macrosomia incidence, thereby to explore the validity of an enhanced nutrition management model for all pregnant women in reducing the incidence of macrosomia.Results:The number of deliveries included annually from 2018 to 2023 was 14 578, 15 413, 11 496, 11 146, 10 396, and 10 164, respectively. Maternal pre-pregnancy body mass indices in 2022 to 2023 were higher than those in 2018 to 2021 [(22.26±3.50) and (22.23±3.65) vs (21.87±3.27), (21.82±3.31), (21.86±3.34) and (21.94±3.39) kg/m2, respectively (all P<0.05)]. Neonatal birth weights in 2021 to 2022 were lower than those in 2018 to 2020 [(3 271±514) and (3 270±513) vs (3 323±504), (3 314±500), and (3 315±510) g], and the birth weight in 2023 was further reduced compared to that in 2018 to 2022 [(3 236±506) vs (3 323±504), (3 314±500), (3 315±510), (3 271±514) and (3 270±513) g] (all P<0.05). The incidence of macrosomia in 2021 to 2022 was lower than those in 2018 to 2020 (5.55%, 5.75% vs 6.97%, 6.68%, 6.67%), and the incidence in 2023 further decreased compared to those in 2018 to 2022 (4.16% vs 6.97%, 6.68%, 6.67%, 5.55%, 5.75%) (all P<0.05). Conclusion:The enhanced nutrition management model for all pregnant women effectively reduces the incidence of macrosomia, demonstrating significant clinical value for widespread implementation.

Objective:To investigate the relationship between the early pregnancy triglyceride-glucose (TyG) index and gestational diabetes mellitus (GDM) in twin pregnancies.Methods:This retrospective study involved twin-pregnant women who visited Beijing Obstetrics and Gynecology Hospital, Capital Medical University from October 2015 to February 2021. Based on the results of the 75 g oral glucose tolerance test (OGTT) performed at 24-28 weeks of gestation, the women were divided into the GDM and the control groups. The groups were further stratified based on maternal age (<35 years or ≥35 years), pre-pregnancy body mass index (BMI) (<24.0 or ≥24.0 kg/m2), and conception method [assisted reproductive technology (ART) or natural conception]. The correlation between early pregnancy TyG index and GDM, as well as the predictive value of the early pregnancy TyG index for the risk of GDM in twin pregnancies, were analyzed. The TyG index in early pregnancy was then divided into tertiles, and the risks of GDM in low, medium, and high TyG index groups were analyzed. Statistical analyses were performed using independent sample t-test, non-parametric test, Chi-square test, and binary logistic regression analysis. Receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive value of the early pregnancy TyG index for GDM in twin pregnancies. Results:(1) A total of 1 684 twin-pregnant women were included, with an average age of 32.3 years (29.8-34.9 years) and a pre-pregnancy BMI of 22.0 kg/m2 (20.0-24.3 kg/m2). Among them, 319 (18.9%) were multiparas, 982 (58.3%) conceived through ART, and 357 (21.2%) were monochorionic twins. Of the 1 684 women, 367 (21.8%) were diagnosed with GDM (GDM group), whereas the remaining 1 317 were classified as the control group. (2) Compared to the control group, the GDM group had older maternal age [(32.2±3.7) years vs. (33.3±3.8) years, t=-4.92], higher pre-pregnancy weight, and BMI [57.5 kg (52.0-65.0 kg) vs. 60.0 kg (55.0-67.3 kg), U=279 901.50; 21.8 kg/m2 (19.8-24.0 kg/m2) vs. 22.9 kg/m2 (20.9-25.5 kg/m2), U=288 435.00]. The proportions of a family history of diabetes, history of GDM and polycystic ovary syndrome (PCOS) were all higher in the GDM group compared to the control group [9.6% (127/1 317) vs. 19.1% (70/367), χ 2=24.71; 0.8% (2/1 317) vs. 10.8% (8/367), χ 2=20.00; 9.1% (120/1 317) vs. 15.3% (56/367), χ 2=11.59] (all P<0.001). The GDM group had higher early pregnancy fasting blood glucose, triglyceride, and TyG indices compared to the control group [4.51 mmol/L (4.28-4.75 mmol/L) vs. 4.68 mmol/L (4.42-4.97 mmol/L), U=7.14; 1.23 mmol/L (0.93-1.57 mmol/L) vs. 1.43 mmol/L (1.09-1.89 mmol/L), U=4.81; 8.39±0.41 vs. 8.59±0.43, t=6.46]. The incidence of gestational anemia and weight gain were lower in the GDM group compared to the control group [39.2% (516/1 317) vs. 33.0% (121/367), χ 2=4.71; 17.0 kg (13.7-20.5 kg) vs. 15.0 kg (12.0-18.3 kg), U=187 966.00] (all P<0.05). The proportion of male newborns in the GDM group was higher than in the control group [52.5% (1 384/2 634) vs. 46.7% (343/734), χ 2=7.77, P=0.005]. (3) Early pregnancy TyG index was associated with GDM in twin pregnancies ( OR=3.164, 95% CI: 2.371-4.220, P<0.001). After adjusting for maternal age, pre-pregnancy BMI, history of GDM, history of macrosomia, and family history of diabetes, the early pregnancy TyG index remained associated with GDM ( OR=2.560, 95% CI: 1.884-3.478, P<0.001). Analysis of the early pregnancy TyG index divided into tertiles (corresponding TyG indices of 8.25 and 8.59) revealed that, compared to those with a low TyG index, those with a mid TyG index had a 0.555-fold increased risk of GDM ( OR=1.555, 95% CI: 1.119-2.159, P=0.008), and those with a high TyG index had a 1.564-fold increased risk of GDM ( OR=2.564, 95% CI: 1.836-3.530, P<0.001). Stratified analysis by age, BMI, and mode of conception showed that the early pregnancy TyG index was associated with GDM in twin pregnancies (all P<0.001). (4) The threshold value for the early pregnancy TyG index to predict GDM in twin pregnancies was 8.33, with an area under the curve (AUC) of 0.632, 95% CI: 0.600-0.665, sensitivity of 0.744, and specificity of 0.436. The AUC in twin pregnancies for those who conceived via ART was 0.635 (95% CI: 0.593-0.676, P<0.001), slightly higher than in those who conceived naturally (AUC=0.628, 95% CI: 0.576-0.681, P<0.001). After adjusting for maternal age, pre-pregnancy BMI, history of GDM, and family history of diabetes, the AUC for the early pregnancy TyG index to predict GDM in twin pregnancies was 0.675 (95% CI: 0.644-0.707). For those who conceived via ART, the AUC (95% CI) was 0.675 (0.634-0.717), slightly lower than for those who conceived naturally [0.682 (0.632-0.733)] (all P<0.001). Conclusion:A high TyG index in the first trimester is a risk factor for GDM in twin pregnancies, but its predictive value for GDM in twin pregnancies needs further research to be confirmed.

The concept of holism is the core idea of traditional Chinese medicine (TCM). Various organs and tissues coordinate with each other to maintain the body's life activities, with a close and mutual influence between the spleen, stomach, and the central nervous system (brain). The gut-brain axis plays an important bridging role between the digestive system and the central nervous system, achieving bidirectional information exchange between the brain and the gastrointestinal tract through complex neuroendocrine and immune mechanisms. The theory of cross-organ interaction involves the mutual influence, coordination, and integration between different organs and systems; multimodality, on the other hand, utilizes multiple sensory modalities, such as vision, hearing, and touch, to convey information. By combining TCM theory with the gut-brain axis theory, a cross-organ multimodal characterization system is established to explore its mechanism and application value in refractory diseases such as functional gastrointestinal disorders, precancerous gastrointestinal diseases, Alzheimer's disease, Parkinson's syndrome, type 2 diabetes, and depression.

Objective:This study aimed to evaluate the effects of hypertensive disorders of pregnancy (HDP), including their clinical subtypes, on neonatal heel blood methionine levels and explore potential dose-effect relationships.Methods:A retrospective cohort study was conducted among 11 007 singleton pregnancies and their neonates delivered at Beijing Obstetrics and Gynecology Hospital, Capital Medical University, from July 2021 to October 2022. Participants were stratified into an HDP group [ n=992; 480 with gestational hypertension, 512 with preeclampsia (including 229 severe cases)] and a non-HDP control group ( n=10 015). Methionine concentrations were measured using tandem mass spectrometry from heel blood dried filter paper samples collected within 72 hours post-delivery. Statistical analyses included non-parametric tests to compare intergroup differences, multiple linear regression to evaluate the effects of HDP on methionine levels, and multivariate logistic regression to identify risk factors for hypermethioninemia (>50 μmol/L). Results:(1) Baseline data: Maternal age was higher in the HDP group compared to controls [33 (30-36) vs. 33 (30-35) years, Z=-2.29, P=0.022], with elevated pre-pregnancy body mass index (BMI) [23 (21-26) vs. 21 (20-23) kg/m2, Z=-17.15, P<0.001] and increased gestational hyperglycemia prevalence [26.5% (263/992) vs. 19.8% (1 986/10 015), χ2=27.95, P<0.001]. (2) Methionine level: Neonates in the HDP group exhibited higher methionine levels [25.96 (21.58-30.89) vs. 24.77 (20.45-29.53) μmol/L, Z=-5.26, P<0.001], with a severity-dependent gradient: gestational hypertension [25.83 (21.77-30.61)], preeclampsia [26.05 (21.23-31.11)], and severe preeclampsia [26.15 (21.25-32.13)] ( Z=2.97, 3.92, 2.26; all P<0.05). Trend analysis confirmed a dose-effect relationship between HDP and neonatal methionine ( χ2=7.82, P=0.005). (3) Multivariate analysis: After adjusting for confounding factors such as maternal age and BMI, HDP remained independently associated with elevated methionine levels ( β=0.93, 95% CI: 0.47-1.40, t=3.92, P<0.001) and increased hypermethioninemia risk ( OR=2.75, 95% CI: 1.13-6.68). Subgroup analysis revealed ORs of 3.20 (95% CI: 1.07-9.57) for gestational hypertension, 3.25 (95% CI: 1.09-9.72) for preeclampsia, and 5.23 (95% CI: 1.54-17.82) for severe preeclampsia (all P<0.05). (4) Neonatal outcomes: Neonates in the HDP group had lower birth weights [3 230 (2 910-3 560) vs. 3 335 (3 070-3 600) g, Z=-7.43, P<0.001] and higher fetal growth restriction rates [10.3% (102/992) vs. 3.1% (306/10 015), χ2=136.47, P<0.001]. Conclusions:HDP demonstrates an elevation of neonatal methionine levels, correlating with disease severity, particularly in severe preeclampsia. These findings underscore the necessity for enhanced metabolic monitoring and long-term follow-up in offspring of mothers with HDP, especially those with severe preeclampsia.

Objective:To explore the efficacy of interventional therapy for transplant renal artery stenosis (TRAS) and the 1-, 2-, and 3-year survival rates of recipients after treatment.Methods:This is a retrospective case series study. Forty TRAS recipients who underwent interventional treatment at Zhengzhou University People's Hospital between April 2016 and April 2021 were included as the study group. The Kaplan-Meier method was used to calculate the survival rates of the transplanted kidneys and recipients, and survival curves were plotted. The improvement in graft function and blood pressure after interventional therapy in the study group was further analyzed.Results:The 1- and 3-year graft survival rates in the study group after interventional therapy were 87.5% and 82.5%, respectively; the 1-, 2-, and 3-year recipient survival rates were all 100%. One month after interventional therapy, the peak systolic velocity (PSV) and resistance index (RI) of the transplanted kidneys were (235.4±135.1) cm/s and 0.60±0.07, respectively, which were significantly different from the pre-treatment values [(482.8±180.6) cm/s and 0.52±0.12, respectively; both P<0.001]. Serum creatinine levels at 1, 2, and 3 years after interventional therapy were (166.6±93.7) μmol/L, (137.4±57.2) μmol/L, and (137.4±57.9) μmol/L, respectively, all significantly lower than the pre-treatment level [(242.9±156.8) μmol/L; P=0.001, P<0.001, and P<0.001, respectively]. Systolic blood pressure at 1, 2, and 3 years after treatment was (138.5±11.1) mmHg (1 mmHg=0.133 kPa), (134.0±12.0) mmHg, and (130.8±10.8) mmHg, respectively, all significantly lower than the pre-treatment value [(153.8±9.8) mmHg; all P<0.001]. Diastolic blood pressure at 1, 2, and 3 years after treatment was (84.4±9.9) mmHg, (83.7±10.1) mmHg, and (81.9±6.9) mmHg, respectively, all significantly lower than the pre-treatment value [(93.5±12.8) mmHg; P=0.002, P=0.001, and P<0.001, respectively]. Conclusions:Interventional therapy can enable the majority of kidney transplant recipients diagnosed with TRAS to avoid the need for further dialysis, and it has positive effects on both transplant renal function and blood pressure control.

Objective:To investigate the relationship between the early pregnancy triglyceride-glucose (TyG) index and gestational diabetes mellitus (GDM) in twin pregnancies.Methods:This retrospective study involved twin-pregnant women who visited Beijing Obstetrics and Gynecology Hospital, Capital Medical University from October 2015 to February 2021. Based on the results of the 75 g oral glucose tolerance test (OGTT) performed at 24-28 weeks of gestation, the women were divided into the GDM and the control groups. The groups were further stratified based on maternal age (<35 years or ≥35 years), pre-pregnancy body mass index (BMI) (<24.0 or ≥24.0 kg/m2), and conception method [assisted reproductive technology (ART) or natural conception]. The correlation between early pregnancy TyG index and GDM, as well as the predictive value of the early pregnancy TyG index for the risk of GDM in twin pregnancies, were analyzed. The TyG index in early pregnancy was then divided into tertiles, and the risks of GDM in low, medium, and high TyG index groups were analyzed. Statistical analyses were performed using independent sample t-test, non-parametric test, Chi-square test, and binary logistic regression analysis. Receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive value of the early pregnancy TyG index for GDM in twin pregnancies. Results:(1) A total of 1 684 twin-pregnant women were included, with an average age of 32.3 years (29.8-34.9 years) and a pre-pregnancy BMI of 22.0 kg/m2 (20.0-24.3 kg/m2). Among them, 319 (18.9%) were multiparas, 982 (58.3%) conceived through ART, and 357 (21.2%) were monochorionic twins. Of the 1 684 women, 367 (21.8%) were diagnosed with GDM (GDM group), whereas the remaining 1 317 were classified as the control group. (2) Compared to the control group, the GDM group had older maternal age [(32.2±3.7) years vs. (33.3±3.8) years, t=-4.92], higher pre-pregnancy weight, and BMI [57.5 kg (52.0-65.0 kg) vs. 60.0 kg (55.0-67.3 kg), U=279 901.50; 21.8 kg/m2 (19.8-24.0 kg/m2) vs. 22.9 kg/m2 (20.9-25.5 kg/m2), U=288 435.00]. The proportions of a family history of diabetes, history of GDM and polycystic ovary syndrome (PCOS) were all higher in the GDM group compared to the control group [9.6% (127/1 317) vs. 19.1% (70/367), χ 2=24.71; 0.8% (2/1 317) vs. 10.8% (8/367), χ 2=20.00; 9.1% (120/1 317) vs. 15.3% (56/367), χ 2=11.59] (all P<0.001). The GDM group had higher early pregnancy fasting blood glucose, triglyceride, and TyG indices compared to the control group [4.51 mmol/L (4.28-4.75 mmol/L) vs. 4.68 mmol/L (4.42-4.97 mmol/L), U=7.14; 1.23 mmol/L (0.93-1.57 mmol/L) vs. 1.43 mmol/L (1.09-1.89 mmol/L), U=4.81; 8.39±0.41 vs. 8.59±0.43, t=6.46]. The incidence of gestational anemia and weight gain were lower in the GDM group compared to the control group [39.2% (516/1 317) vs. 33.0% (121/367), χ 2=4.71; 17.0 kg (13.7-20.5 kg) vs. 15.0 kg (12.0-18.3 kg), U=187 966.00] (all P<0.05). The proportion of male newborns in the GDM group was higher than in the control group [52.5% (1 384/2 634) vs. 46.7% (343/734), χ 2=7.77, P=0.005]. (3) Early pregnancy TyG index was associated with GDM in twin pregnancies ( OR=3.164, 95% CI: 2.371-4.220, P<0.001). After adjusting for maternal age, pre-pregnancy BMI, history of GDM, history of macrosomia, and family history of diabetes, the early pregnancy TyG index remained associated with GDM ( OR=2.560, 95% CI: 1.884-3.478, P<0.001). Analysis of the early pregnancy TyG index divided into tertiles (corresponding TyG indices of 8.25 and 8.59) revealed that, compared to those with a low TyG index, those with a mid TyG index had a 0.555-fold increased risk of GDM ( OR=1.555, 95% CI: 1.119-2.159, P=0.008), and those with a high TyG index had a 1.564-fold increased risk of GDM ( OR=2.564, 95% CI: 1.836-3.530, P<0.001). Stratified analysis by age, BMI, and mode of conception showed that the early pregnancy TyG index was associated with GDM in twin pregnancies (all P<0.001). (4) The threshold value for the early pregnancy TyG index to predict GDM in twin pregnancies was 8.33, with an area under the curve (AUC) of 0.632, 95% CI: 0.600-0.665, sensitivity of 0.744, and specificity of 0.436. The AUC in twin pregnancies for those who conceived via ART was 0.635 (95% CI: 0.593-0.676, P<0.001), slightly higher than in those who conceived naturally (AUC=0.628, 95% CI: 0.576-0.681, P<0.001). After adjusting for maternal age, pre-pregnancy BMI, history of GDM, and family history of diabetes, the AUC for the early pregnancy TyG index to predict GDM in twin pregnancies was 0.675 (95% CI: 0.644-0.707). For those who conceived via ART, the AUC (95% CI) was 0.675 (0.634-0.717), slightly lower than for those who conceived naturally [0.682 (0.632-0.733)] (all P<0.001). Conclusion:A high TyG index in the first trimester is a risk factor for GDM in twin pregnancies, but its predictive value for GDM in twin pregnancies needs further research to be confirmed.
