A systematic review and meta-analysis of intraperitoneal anastomosis versus extraperitoneal anastomosis in laparoscopic left colectomy.

Background: The effectiveness of the anastomosis method for laparoscopic left colectomy (LLC) remains inconclusive. Thus, a systematic review and meta-analysis were conducted to compare the outcomes between intraperitoneal anastomosis (IPA) and extraperitoneal anastomosis(EPA)in LLC. Methods: PubMed, Embase, the Cochrane Library, CNKI, and WanFangData were systematically searched for relevant literature. The literature was screened independently by two groups, and data were extracted and evaluated for bias. Meta-analysis was performed using Revman5.4 software. Results: Twelve studies with a total of 1,278 patients were included in our meta-analysis. Compared with the EPA group, the IPA group had less blood loss [odds ratio (OR)=-20.32, 95% confidence interval (CI) (-27.98-12.65), p<0.00001], a lower overall complication rate [OR=0.45, 95% CI (0.33-0.63), p<0.00001], fewer non-severe complications [OR=0.44, 95% CI (0.30-0.64), p<0.0001], and fewer surgical site infections [OR=0.39, 95% CI (0.21-0.71), p=0.002]. Additionally, a longer operation time appeared in the multicenter and propensity score matching (PSM) subgroups of the IPA group. Furthermore, patients in the IPA group had an earlier exhaust time and shorter hospital stays. There were no significant differences between the two groups regarding severe complications, anastomose-related complications, postoperative blood transfusion, ileus, reoperation rate, time to stool, pathologic sample length, and lymph node dissection number. Conclusion: IPA seems more advantageous than EPA for patients receiving LCC in terms of complications and postoperative recovery and has similar oncological outcomes. However, it may take longer and be more difficult to perform. Systematic Review Registration: https://www.crd.york.ac.uk/PROSPERO/#recordDetails PROSPERO, identifier (CRD4202454391).

Specific depressive symptoms, body mass index and diabetes in middle-aged and older Chinese adults: Analysis of data from the China Health and Retirement Longitudinal Study (CHARLS).

BACKGROUND: This study examined the association between specific depressive symptoms and incident diabetes, and whether overweight or obesity mediates this relationship among middle-aged and older adults in China. METHODS: In a nationally representative prospective cohort study of 11,893 middle-aged and older Chinese adults without baseline diabetes, we used Cox models to assess the association between depressive symptoms and diabetes. The quantile g-computation (qgcomp) model evaluated the contribution of 10 specific depressive symptoms to diabetes risk, and a two-stage regression method explored the mediation effect of overweight or obesity. RESULTS: Over a median follow-up of 7.1 years, 1,314 cases of diabetes were identified. Elevated depressive symptoms were associated with increased diabetes risk (HR 1.23; 95 % CI 1.09-1.38). Eight out of 10 depressive symptoms were significantly associated to diabetes, with loneliness (weight = 18 %; HR 1.23; 95 % CI 1.10-1.39), restless sleep (weight = 17 %; HR 1.16; 95 % CI 1.04-1.29), and bother (weight = 15 %; HR 1.19; 95 % CI 1.07-1.33) being the primary contributors. Mediation analysis showed that overweight and obesity reduced the depression-diabetes risk association by 8.21 % and 12.61 %, respectively. LIMITATIONS: Diagnosis of diabetes was self-reported. CONCLUSIONS: Eight out of ten specific depressive symptoms were associated to diabetes, overweight and obesity may partially mitigate the effect of depressive symptoms on diabetes among middle-aged and older adults in China. CLINICAL IMPLICATIONS: Our results highlight the importance of tailoring diabetes prevention and management strategies according to specific depressive symptoms among middle-aged and older adults in China.

The associations between gut microbiota and fecal metabolites with intelligence quotient in preschoolers.

BACKGROUND: The awareness of the association between the gut microbiota and human intelligence levels is increasing, but the findings are inconsistent. Furthermore, few research have explored the potential role of gut microbial metabolites in this association. This study aimed to investigate the associations of the gut microbiota and fecal metabolome with intelligence quotient (IQ) in preschoolers. METHODS: The 16 S rRNA sequencing and widely targeted metabolomics were applied to analyze the gut microbiota and fecal metabolites of 150 children aged 3-6 years. The Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition (WPPSI-IV) was used to assess the cognitive competence. RESULTS: The observed species index, gut microbiome health index, and microbial dysbiosis index presented significant differences between children with full-scale IQ (FSIQ) below the borderline (G1) and those with average or above-average (all P < 0.05). The abundance of Acinetobacter, Blautia, Faecalibacterium, Prevotella_9, Subdoligranulum, Collinsella, Dialister, Holdemanella, and Methanobrevibacter was significantly associated with preschooler's WPPSI-IV scores (P < 0.05). In all, 87 differential metabolites were identified, mainly including amino acid and its metabolites, fatty acyl, and benzene and substituted derivatives. The differential fecal metabolites carnitine C20:1-OH, 4-hydroxydebrisoquine, pantothenol, creatine, N,N-bis(2-hydroxyethyl) dodecanamide, FFA(20:5), zerumbone, (R)-(-)-2-phenylpropionic acid, M-toluene acetic acid, trans-cinnamaldehyde, isonicotinic acid, val-arg, traumatin, and 3-methyl-4-hydroxybenzaldehyde were significantly associated with the preschooler's WPPSI-IV scores (P < 0.05). The combination of Acinetobacter, Isonicotinic acid, and 3-methyl-4-hydroxybenzaldehydenine may demonstrate increased discriminatory power for preschoolers in G1. CONCLUSION: This study reveals a potential association between gut microbiome and metabolites with IQ in preschoolers, providing new directions for future research and practical applications. However, due to limitations such as the small sample size, unclear causality, and the complexity of metabolites, more validation studies are still needed to further elucidate the mechanisms and stability of these associations.

Pancreatic necrosis volume is closely associated with late-onset vascular complications after discharge in necrotizing pancreatitis.

PURPOSE: To explore the incidence, dynamic changes, prognostic factors and prognosis of late-onset vascular complications after discharge in patients with necrotizing pancreatitis (NP), and determine the relationship between the pancreatic necrosis volume (PNV) and late-onset vascular complications. METHODS: This was a retrospective cohort study that included NP patients who did not have any vascular complications during index hospitalization. Computed tomography (CT) examinations were performed, and the PNV was calculated based on the picture archiving and communication system. Multivariate logistic regression analysis was employed to determine the potential prognostic factors for late-onset vascular complications after discharge. RESULTS: A total of 35.6 % (37/104) of the patients had late-onset portal venous system involvement during the one-year follow-up period, including 35 patients with stenosis and 2 patients with occlusion. No venous thrombosis or arterial vascular complications were observed. PNV > 134 cm3 (OR, 7.08, 95 % CI 1.83-27.36; P = 0.005) and pancreatic necrosis involving the body and/or tail of the pancreas (OR, 10.05; 95 % CI, 2.66-38.02; P = 0.001) were prognostic factors for abnormal patency of the portal venous system. The abnormal patency of the portal venous system tended to persist during follow-up, and gastric varices were observed in 32.4 % (12/37) of the patients in the abnormal patency group without any symptoms. CONCLUSIONS: Late-onset vascular complications involving venous stenosis or occlusion were common in NP patients after discharge, approximately one third of whom developed gastric varices. PNV and the location of necrosis were closely associated with the development of these complications.

Comparative analysis of open and closed tracheal suction systems on mechanical ventilation efficiency in adults: A systematic review and meta-analysis.

BACKGROUND: There are two types of suction methods used clinically: closed tracheal suction system (CTSS) and open tracheal suction system (OTSS). However, the safety and efficacy of these two suction systems for patients remain to be analysed. OBJECTIVE: The objective of this study was to assess the safety and efficacy of OTSSs and CTSSs in adult mechanical ventilation. METHODS: Computer searches were conducted on PubMed, Web of science, MEDLINE, CINAHL, and Cochrane Library databases. The search spanned from the inception of each database to December 2023. Two researchers independently reviewed and extracted data from the literature. Quality assessment was performed using the Cochrane Manual of Systematic Reviews, and meta-analysis was conducted using RevMan 5.3 software. RESULTS: A total of 13 articles, involving 2822 patients, were included in the analysis. The meta-analysis showed that the CTSS could reduce the incidence of ventilator-associated pneumonia (odds ratio [OR] = 0.77, 95% confidence interval [CI]: [0.61, 0.98], P = 0.03). However, no significant difference existed in the microbial colonisation rate in the respiratory tract (OR = 1.40, 95% CI: [0.91, 2.15], P = 0.13), mechanical ventilation time (mean difference = -0.33, 95% CI: [-1.43, 0.78], P = 0.56), length of intensive care unit stay (mean difference = 0.23, 95% CI: [-0.90, 1.35], P = 0.69), and mortality (OR = 1.01, 95% CI: [0.84, 1.22], P = 0.89). CONCLUSION: In comparison to the OTSS, the CTSS proves effective in reducing the incidence of ventilator-associated pneumonia. However, additional high-quality evidence is needed to evaluate respiratory microbial colonisation rates, the duration of mechanical ventilation, length of intensive care unit stay, and mortality.

Metal and Photocatalyst-Free Amide Synthesis via Decarbonylative Condensation of Alkynes and Photoexcited Nitroarenes.

Depending on the intrinsic photoactivity of nitroarenes, we herein developed a practical Brønsted acid-catalyzed decarbonylative amide synthesis from alkynes and photoexcited nitroarenes without any metal or photocatalyst. This method exhibited compatibility with water and air, broad substrate applicability, marvelous functional group tolerance, and wide applications in scale-up synthesis, late-stage functionalization, and total synthesis. Mechanism studies and DFT calculations supported that a 1,3,2-dioxazole intermediate was involved, and gaseous carbon monoxide was the only byproduct during amide construction.

Preparation and characterization of mussel-inspired chitosan/polydopamine films and their feasibility for oral mucosa application.

Oral mucosal lesions (OML), which represent a major public health issue worldwide, include any pathological changes in the oral mucosa, such as ulcers, pigmentation, and swelling. Due to its humid and dynamic complex environment, designing oral mucosal preparations poses significant challenges. Drawing inspiration from mussels, this study employed an eco-friendly one-pot strategy for the preparation of chitosan/polydopamine (CS/PDA) films. We demonstrated that CS-induced polymerization of dopamine monomers under acidic conditions, which might be attributed to the large number of hydrogen bonding sites of CS chains. PDA markedly enhances properties of the CS film and exhibits concentration dependence. At the concentration of 1 wt% PDA, the lap-shear strength and tensile strength of CS/PDA films reached 5.01 ± 0.24 kpa and 4.20 ± 0.78 kpa, respectively, indicating that the mucosal adhesion ability was significantly improved. In comparison with the single CS film, the swelling rate of CS/PDA film decreased by about 30 %. Rheological results also showed that the storage modulus returned to 93 % after cyclic large strain, while the single CS film only recovered to 73 %. Moreover, these films demonstrated good biocompatibility and enhanced oral ulcer healing in rats, providing a new and practical option for the local treatment of OML.

Deep learning based method for predicting DNA N6-methyladenosine sites.

DNA N6 methyladenine (6mA) plays an important role in many biological processes, and accurately identifying its sites helps one to understand its biological effects more comprehensively. Previous traditional experimental methods are very labor-intensive and traditional machine learning methods also seem to be somewhat insufficient as the database of 6mA methylation groups becomes progressively larger, so we propose a deep learning-based method called multi-scale convolutional model based on global response normalization (CG6mA) to solve the prediction problem of 6mA site. This method is tested with other methods on three different kinds of benchmark datasets, and the results show that our model can get more excellent prediction results.

Risk factors of negative diagnosis of MRCP in acute biliary pancreatitis patients with choledocholithiasis.

BACKGROUND: Assessment of the presence of choledocholithiasis is crucial among acute biliary pancreatitis (ABP). Magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasonography (EUS) are widely used to identify the gallstones of common bile duct (CBD). EUS provides better diagnostic accuracy and sensitivity than MRCP but carries a certain risk due to sedation. We investigated the risk factors of negative diagnosis of MRCP in ABP patients with choledocholithiasis for better selection of MRCP or EUS. METHODS: A total of 2321 ABP patients were retrospectively included in this study. Based on the exclusion criteria, 337 ABP patients with negative MRCP results were ultimately included. Among these patients, 75 patients had positive EUS findings. Univariate and multivariate logistic regression models were used to screen the risk factors of negative diagnosis of MRCP in ABP patients with choledocholithiasis. RESULTS: Patients with positive EUS findings were older (62.0 vs. 55.0) and had higher rate of cholecystectomy history (18.7% vs. 7.3%) than those with negative EUS findings. The result of univariate logistic regression showed that the history of cholecystectomy, age and sex were potential risk factors (all p < 0.05). Then after adjusting the other potential risk factors (Direct bilirubin (DBIL), alanine transaminase (ALT), gamma-glutamyl transpeptidase (GGT) and alkaline phosphatase (ALP)), a history of cholecystectomy (OR = 2.859 [1.312,6.23]), older age (1.03 [1.009,1.052]) and male (2.016 [1.152,3.528]) were independent risk factors of negative diagnosis of MRCP in ABP patients with choledocholithiasis. CONCLUSIONS: The history of cholecystectomy, older age and male are independently associated with an increased risk of negative diagnosis of MRCP in ABP patients with choledocholithiasis. We suggest that patients with these risk factors should undergo EUS first, rather than MRCP.

Association between maternal metal exposure during early pregnancy and intelligence in children aged 3-6 years: Results from a Chinese birth cohort.

OBJECTIVE: Maternal environmental metal exposure is common, but long-term prospective epidemiological evidence of its impact on children's intellectual development is still insufficient. METHODS: Data on maternal plasma metal levels and child intelligence were obtained for 211 3-6-year-old children from Guangxi Zhuang Birth Cohort. ICP-MS was employed to detect 17 metals, including 7 essential metals (Mn, Fe, Co, Ni, Cu, Zn, Mo) and 10 non-essential metals (As, Rb, Sr, Cd, Sb, Cs, Ba, W, Pb, U), in maternal plasma samples obtained before 13 weeks of gestation during the initial maternity checkup. Child intelligence was assessed using the Wechsler Intelligence Scale for Children-Fourth Edition. The GLM, RCS and mixture models were used to assess the associations of maternal plasma metal levels with child intelligence quotient (IQ) scores. RESULTS: The GLM analysis revealed that U had a significant adverse effect on child IQ scores in high-dose exposure groups (-9.236 [-18.644, -4.936], p = 0.006) after adjusting for covariates, while Sb showed a linear adverse effect on children's intelligence in the adjusted model (-4.028 [-7.432, -0.626], p = 0.021). BKMR modeling indicated that overall IQ scores decreased as concentrations of non-essential metals mixtures increased after adjusting for essential metal mixtures, consistent with findings from the WQS (ß [95% CI], -8.463 [-14.449, -2.476], p = 0.007) and Qgcomp models (-7.003 [-12.928, -1.078], p = 0.022). Among the non-essential metals, U had the highest negative weight at 37.96%, followed by Pb (23.35%) and Sb (16.91%). Furthermore, potential interactions were observed between metals (Pb and U) and Sb in the study findings. CONCLUSION: Reducing exposure to non-essential metal mixtures, especially U, Sb and Pb, during early pregnancy and ensuring adequate intake of specific essential metal elements could be a critical intervention in addressing childhood intellectual impairment.

A Feasibility Study of AI-Assisted Compressed Sensing in Prostate T2-Weighted Imaging.

RATIONALE AND OBJECTIVES: To evaluate the image quality and PI-RADS scoring performance of prostate T2-weighted imaging (T2WI) based on AI-assisted compressed sensing (ACS). MATERIALS AND METHODS: In this prospective study, adult male urological outpatients or inpatients underwent prostate MRI, including T2WI, diffusion-weighted imaging and apparent diffusion coefficient maps. Three accelerated scanning protocols using parallel imaging (PI) and ACS: T2WIPI, T2WIACS1 and T2WIACS2 were evaluated through comparative analysis. Quantitative analysis included signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), slope profile, and edge rise distance (ERD). Image quality was qualitatively assessed using a five-point Likert scale (ranging from 1 = non-diagnostic to 5 = excellent). PI-RADS scores were determined for the largest or most suspicious lesions in each patient. The Friedman test and one-way ANOVA with post hoc tests were utilized for group comparisons, with statistical significance set at P < 0.05. RESULTS: This study included 40 participants. Compared to PI, ACS reduced acquisition time by over 50%, significantly enhancing the CNR of sagittal and axial T2WI (P < 0.05), significantly improving the image quality of sagittal and axial T2WI (P < 0.05). No significant differences were observed in slope profile, ERD, and PI-RADS scores between groups (P > 0.05). CONCLUSION: ACS reduced prostate T2WI acquisition time by half while improving image quality without affecting PI-RADS scores.

Efficacy of GnRH Pulses in Hypogonadism Secondary to Primary Empty Sella: Case Report.

This study aims to assess the effectiveness of pulsed gonadotropin-releasing hormone (GnRH) micropump replacement therapy in the treatment of hypogonadotropic hypogonadism (HH) caused by primary empty sella (PES).The efficacy of pulsed GnRH replacement therapy using the micropump was evaluated in a middle-aged male patient with HH who had experienced the loss of his only child. Relevant literature was also consulted to compare the differences between pulse GnRH treatment and conventional treatment in terms of the development of secondary sexual characteristics, sex hormone levels, sperm production rate, and sperm activity rate in male patient with HH.In this report, a 45-year-old male diagnosed with HH and PES presented with fatigue and decreased libido. The main characteristics included decreased follicle stimulating hormone (FSH) levels of 0.03 mIU/mL, luteinizing hormone (LH) levels of 0.02 mIU/mL, and testosterone (T) levels of 0.72 nmol/L. Magnetic resonance imaging (MRI) revealed an empty sella. Semen analysis showed a small number of normal sperm with reduced motility. During treatment with the micropump pulse GnRH, the patient experienced no side effects and showed improvements in fatigue, reduced libido, sexual urge, anxiety, and feelings of inferiority. LH, FSH, and T levels returned to normal, while sperm activity rate increased to 79.9%. Ultimately, the patient's spouse achieved a natural pregnancy.Pulsed gonadotropin delivery using the micropump demonstrates good efficacy and tolerability, and aligns more closely with the physiological rhythm of GnRH secretion in the human body.

Two exploratory laparotomies within six days: A case of midgut volvulus in an adult with congenital malrotation.

INTRODUCTION: Midgut volvulus in adults based on congenital malrotation, which required emergency surgery, may occur under the stimulation of adverse factors and is rare and easy to be misdiagnosed. PRESENTATION OF CASE: A young male was taken to the emergency room of a local hospital after six hours abdominal pain. Computed tomography (CT) shows intestinal volvulus and exploratory laparotomy was performed. Postoperative CT revealed remission of small intestinal torsion and congenital malrotation of the midgut. The patient vomited frequently within 48 h after the surgery, and was transferred to our hospital for conservative treatment. After 4 days of conservative treatment, the vomiting symptoms were relieved at first, but worsened again after a liquid diet. CT showed complete duodenal obstruction and exploratory laparotomy was performed again. Congenital malrotation was found, which resulted in midgut volvulus and duodenal obstruction due to anomalous fixation of the mesentery. The bowel was placed in normal anatomical position, and the mesentery was sutured to the posterior abdominal wall. The patient was followed up for 24 months with no complaints. DISCUSSION: Due to the rare incidence and atypical pain clinical manifestations, it is difficult for the congenital malrotation in adults to be diagnosed. Midgut volvulus in adults with malrotation is even rarer and requires emergency operation, and may be misdiagnosed. CONCLUSION: Midgut volvulus with midgut malrotation is very rare in adults. Exploratory laparotomy must be careful to reduce misdiagnosis and recurrence of volvulus.

Prenylated Flavonoids in Sophora flavescens: A Systematic Review of Their Phytochemistry and Pharmacology.

Sophora flavescens has been widely used in traditional Chinese medicine for over 1700 years. This plant is known for its heat-clearing, damp-drying, insecticidal, and diuretic properties. Phytochemical research has identified prenylated flavonoids as a unique class of bioactive compounds in S. flavescens. Recent pharmacological studies reveal that the prenylated flavonoids from S. flavescens (PFS) exhibit potent antitumor, anti-inflammatory, and glycolipid metabolism-regulating activities, offering significant therapeutic benefits for various diseases. However, the pharmacokinetics and toxicological profiles of PFS have not been systematically studied. Despite the diverse biological effects of prenylated flavonoid compounds against similar diseases, their structure-activity relationship is not yet fully understood. This review aims to summarize the latest findings regarding the chemical composition, drug metabolism, pharmacological properties, toxicity, and structure-activity relationship of prenylated flavonoids from S. flavescens. It seeks to highlight their potential for clinical use and suggest directions for future related studies.

Versatile Hyper-Cross-Linked Polymers Derived from Waste Polystyrene: Synthesis, Properties, and Intentional Recycling.

Waste polystyrene contributes considerably to environmental pollution due to its persistent nature, prompting a widespread consensus on the urgent need for viable recycling solutions. Owing to the aromatic groups structure of polystyrene, hyper-cross-linked polymers can be synthesized through the Friedel-Crafts cross-linking reaction using Lewis acids as catalysts. In addition, hyper-cross-linked polystyrene and its carbonaceous counterparts can be used in several important applications, which helps in their efficient recycling. This review systematically explores methods for preparing multifunctional hyper-cross-linked polymers from waste polystyrene and their applications in sustainable recycling. We have comprehensively outlined various synthetic approaches for these polymers and investigated their physical and chemical properties. These multifunctional polymers not only exhibit structural flexibility but also demonstrate diversity in performance, making them suitable for various applications. Through a systematic examination of synthetic methods, we showcase the cutting-edge positions of these materials in the field of hyper-cross-linked polymers. Additionally, we provide in-depth insights into the potential applications of these hyper-cross-linked polymers in intentional recycling, highlighting their important contributions to environmental protection and sustainable development. This research provides valuable references to the fields of sustainable materials science and waste management, encouraging further exploration of innovative approaches for the utilization of discarded polystyrene.

Relationship of urinary glyphosate concentrations with glycosylated hemoglobin and diabetes in US adults: a cross-sectional study.

BACKGROUND: Glyphosate is a commonly used herbicide worldwide and is purportedly associated with multiple health effects. Research assessing the association of glyphosate concentrations with glycosylated hemoglobin (HbA1c) levels and the prevalence of diabetes is scarce. We sought to evaluate the association between urinary glyphosate levels and HbA1c levels and the prevalence of diabetes. METHODS: A total of 2,745 adults in the National Health and Nutrition Examination Survey from 2013 to 2016 were included in this study. Generalized linear models (GLM) were applied to evaluate the associations of glyphosate concentrations with HbA1c levels and the prevalence of diabetes. The dose-response relationship was examined using restricted cubic splines (RCS). RESULTS: Significantly positive correlations of urinary glyphosate concentrations with HbA1c levels (percentage change: 1.45; 95% CI: 0.95, 1.96; P < 0.001) and the prevalence of diabetes (OR: 1.45; 95% CI: 1.24, 1.68; P < 0.001) were found after adjustment. Compared with the lowest quartile of glyphosate levels, the highest quartile was positively associated with HbA1c levels (percentage change: 4.19; 95% CI: 2.54, 5.85; P < 0.001) and the prevalence of diabetes (OR: 1.89; 95% CI: 1.37, 2.63; P < 0.001). The RCS curves demonstrated a monotonically increasing dose-response relationship between urinary glyphosate levels and the prevalence of diabetes and HbA1c levels. CONCLUSIONS: Urinary glyphosate concentrations are positively associated with HBA1c levels and the prevalence of diabetes. To verify our findings, additional large-scale prospective investigations are required.

Analysis of Clinical Trials Using Anti-Tumor Traditional Chinese Medicine Monomers.

The potential anti-cancer effect of traditional Chinese medicine (TCM) monomers has been widely studied due to their advantages of well-defined structure, clear therapeutic effects, and easy quality control during the manufacturing process. However, clinical trial information on these monomers is scarce, resulting in a lack of knowledge regarding the research progress, efficacy, and adverse reactions at the clinical stage. Therefore, this study systematically reviewed the clinical trials on the anti-cancer effect of TCM monomers registered in the Clinicaltrials.gov website before 2023.4.30, paying special attention to the trials on tumors, aiming to explore the research results and development prospects in this field. A total of 1982 trials were started using 69 of the 131 TCM monomers. The number of clinical trials performed each year showed an overall upward trend. However, only 26 monomers entered into 519 interventional anti-tumor trials, with vinblastine (194, 37.38%) and camptothecin (146, 28.13%) being the most used. A total of 45 tumors were studied in these 519 trials, with lymphoma (112, 21.58%) being the most frequently studied. Clinical trials are also unevenly distributed across locations and sponsors/collaborators. The location and the sponsor/collaborator with the highest number of performed trials were the United States (651,32.85%) and NIH (77). Therefore, China and its institutions still have large room for progress in promoting TCM monomers in anti-tumor clinical trials. In the next step, priority should be given to the improvement of the research and development ability of domestic enterprises, universities and other institutions, using modern scientific and technological means to solve the problems of poor water solubility and strong toxic and side effects of monomers, so as to promote the clinical research of TCM monomers.

Interacting and joint effects of triglyceride-glucose index and hypertension on stroke risk in middle-aged and older Chinese adults: a population-based prospective cohort study.

Background: Triglyceride-glucose (TyG) index and hypertension were well-established risk factors for stroke. And TyG index was associated with hypertension. However, no prior study has investigated the interactive effects of the TyG index and hypertension on stroke. This study examined whether hypertension mediates associations of TyG index with incident stroke and the extent of interaction or joint relations of TyG index and hypertension with stroke in middle-aged and older Chinese adults. Methods: The China Health and Retirement Longitudinal Study (CHARLS) is an ongoing nationally representative prospective cohort study initiated in 2011. This cohort study included 9,145 middle-aged and older Chinese adults without stroke at baseline. The eposures were TyG index and the logarithmized product of hypertension, as determined during the baseline health examination. The main outcome was self-reported physician-diagnosed stroke which followed up from June 1, 2011, to June 30, 2018. Results: Of the 9,145 participants, 4,251 were men (46.5%); the mean (SD) age was 59.20 (9.33) years. During a median follow-up of 7.1 years, 637 (7.0%) participants developed stroke. In multivariable-adjusted models, the TyG index was significantly associated with the risk of hypertension [odds ratio (OR) per 1-SD increase, 1.29; 95% CI, 1.19-1.41] and stroke [hazard ratio (HR) per 1-SD increase, 1.16; 95% CI, 1.02-1.33]. Both multiplicative and additive interactions were observed between TyG index and hypertension on stroke (HR for multiplicative: 2.34, 95% CI, 1.57-3.48; Synergy index: 4.13, 95% CI, 2.73-6.25). Mediation analysis showed that 20.0% of the association between TyG index and stroke was mediated through hypertension. Conclusions: This study suggests a synergistic effect of TyG index and hypertension on stroke, and a small proportion of the association between TyG index and stroke was mediated by hypertension, indicating the benefit of coordinated control strategies for both exposures.

Associations between maternal exposure to multiple metals and metalloids and blood pressure in preschool children: A mixture-based approach.

BACKGROUND: Exposure to metals during pregnancy can potentially influence blood pressure (BP) in children, but few studies have examined the mixed effects of prenatal metal exposure on childhood BP. We aimed to assess the individual and combined effects of prenatal metal and metalloid exposure on BP in preschool children. METHODS: A total of 217 mother-child pairs were selected from the Zhuang Birth Cohort in Guangxi, China. The maternal plasma concentrations of 20 metals [e.g. lead (Pb), rubidium (Rb), cesium (Cs), and zinc (Zn)] in early pregnancy were measured by inductively coupled plasmamass spectrometry. Childhood BP was measured in August 2021. The effects of prenatal metal exposure on childhood BP were explored by generalized linear models, restricted cubic spline and Bayesian kernel machine regression (BKMR) models. RESULTS: In total children, each unit increase in the log10-transformed maternal Rb concentration was associated with a 10.82-mmHg decrease (95% CI: -19.40, -2.24) in childhood diastolic BP (DBP), and each unit increase in the log10-transformed maternal Cs and Zn concentrations was associated with a 9.67-mmHg (95% CI: -16.72, -2.61) and 4.37-mmHg (95% CI: -8.68, -0.062) decrease in childhood pulse pressure (PP), respectively. The log10-transformed Rb and Cs concentrations were linearly related to DBP (P nonlinear=0.603) and PP (P nonlinear=0.962), respectively. Furthermore, an inverse association was observed between the log10-transformed Cs concentration and PP (ß =-12.18; 95% CI: -22.82, -1.54) in girls, and between the log10-transformed Rb concentration and DBP (ß =-12.54; 95% CI: -23.87, -1.21) in boys, while there was an increasing association between the log10-transformed Pb concentration and DBP there was an increasing in boys (ß =6.06; 95% CI: 0.36, 11.77). Additionally, a U-shaped relationship was observed between the log10-transformed Pb concentration and SBP (P nonlinear=0.015) and DBP (P nonlinear=0.041) in boys. Although there was no statistically signiffcant difference, there was an inverse trend in the combined effect of maternal metal mixture exposure on childhood BP among both the total children and girls in BKMR. CONCLUSIONS: Prenatal exposure to both individual and mixtures of metals and metalloids influences BP in preschool children, potentially leading to nonlinear and sex-specific effects.

Dual modifying of MAVS at lysine 7 by SIRT3-catalyzed deacetylation and SIRT5-catalyzed desuccinylation orchestrates antiviral innate immunity.

To effectively protect the host from viral infection while avoiding excessive immunopathology, the innate immune response must be tightly controlled. However, the precise regulation of antiviral innate immunity and the underlying mechanisms remain unclear. Here, we find that sirtuin3 (SIRT3) interacts with mitochondrial antiviral signaling protein (MAVS) to catalyze MAVS deacetylation at lysine residue 7 (K7), which promotes MAVS aggregation, as well as TANK-binding kinase I and IRF3 phosphorylation, resulting in increased MAVS activation and enhanced type I interferon signaling. Consistent with these findings, loss of Sirt3 in mice and zebrafish renders them more susceptible to viral infection compared to their wild-type (WT) siblings. However, Sirt3 and Sirt5 double-deficient mice exhibit the same viral susceptibility as their WT littermates, suggesting that loss of Sirt5 in Sirt3-deficient mice may counteract the increased viral susceptibility displayed in Sirt3-deficient mice. Thus, we not only demonstrate that SIRT3 positively regulates antiviral immunity in vitro and in vivo, likely via MAVS, but also uncover a previously unrecognized mechanism by which SIRT3 acts as an accelerator and SIRT5 as a brake to orchestrate antiviral innate immunity.
