Objective: To analyze the effects of maternal gestational weight gain and pre pregnancy body mass index (BMI) on the weight of preschool children,so as to provide scientific basis for prevention and treatment of overweight and obesity in children. Methods: Based on Jiangmen maternal and child health information platform, annual physical examination data of 3-6 years old preschool children from all nurseries and kindergartens in Jiangmen were collected from January to December 2024. A unique identification was made according to the mother s ID number and delivery date, and retrospective data collection was conducted on the platform to obtain pre pregnancy and pregnancy related information for 46 481 mothers. The Chi-square test,two way ordered variable analysis and Logistic regression analysis were used to compare the effects of maternal pre pregnancy BMI and gestational weight gain on overweight and obesity among preschool children. Results: A total of 5 168 (11.12%) children were overweight and obese, and the proportion of overweight and obesity in the 6 year old group was the highest (12.86%). There were significant differences in the detection rates of overweight and obesity between boys and girls ( χ 2=155.38), and there were also significant gender differences in the age groups of 4, 5 and 6 years ( χ 2=17.08, 96.97, 66.27)(all P <0.01). Through trend χ 2 test, the overall detection rates of overweight and obesity, as well as those for boys, increased with age ( χ 2 trend =49.36,60.54, both P <0.01). The BMI group of preschool children was correlated with the BMI group of their mothers before pregnancy and the weight gain group during pregnancy （χ 2= 1 250.64, 157.01, both P <0.01) and the proportion of children with higher BMI levels showed an upward trend with the improvement of their mothers pre-pregnancy BMI levels or gestational weight gain levels ( Gamma =0.13, 0.10, both P <0.01). Multiple Logistic regression analysis showed that pre pregnancy BMI groups as overweight ( OR =1.590, 1.922), obesity ( OR =2.100, 2.921 ), and male gender of the children ( OR =1.213, 1.763)，and newborns excessive birth weight( OR =1.001，1.001) increased the risks of overweight and obesity in preschool children; maternal gestational weight gain insufficiency ( OR =1.374) and advanced maternal age at the first prenatal visit ( OR =1.012) increased the risks of obesity in preschool children; maternal gestational weight gain deficiency or excess ( OR =1.324,1.118) increased the risk of overweight in preschool children (all P <0.01). Conclusions Maternal pre-pregnancy overweight and obesity and insufficient or excessive gestational weight gain increase the risk of overweight and obesity in preschool children. It is necessary to strengthen weight management before and during pregnancy to reduce the occurrence of childhood overweight and obesity.

Objective:To analyse the clinical effect of percutaneous transhepatic papillary balloon dilatation (PTPBD) combined with lithotriptic basket in the treatment of large-diameter common bile duct stone (CBDS) after percutaneous transhepatic cholangia drainage (PTCD).Methods:The clinical data of 50 patients treated with PTPBD combined with lithotriptic basket after PTCD under digital subtraction angiography (DSA) for large-diameter CBDS in the Department of Interventional Radiology, the Second Affiliated Hospital of Nantong University from October 2021 to September 2024 were retrospectively analyzed, including 38 males and 12 females, aged (57.6±3.6) years. Clinical data, including gender, age, long diameter of the stone, and surgery-related complications, were recorded. Changes in leukocyte count, total bilirubin, alanine transaminase and C-reactive protein were compared before PTCD and on the 5th postoperative day.Results:All 50 cases were successfully treated with PTCD. Significant improvements were observed in white blood cell count [(7.35±2.36)×10 9/L vs. (11.34±2.81)×10 9/L], total bilirubin [(27.58±6.24) μmol/L vs. (74.35±12.26) μmol/L], alanine transaminase [(41.25±8.65) U/L vs. (141.41±29.16) U/L] and C-reactive protein [(39.34±13.45) mg/L vs. (81.43±31.35) mg/L] before and after PTCD (all P<0.001). The time interval between PTCD and PTPBD was (14.46±1.01) d. Among the 50 patients, 48 cases (96.0%) were successfully treated with PTPBD combined with a lithotriptic basket, while 2 cases (4.0%) failed due to the basket's inability to retrieve the stones. Among the 50 patients after PTCD, 2 cases (4.0%) of abdominal pain, 2 cases (4.0%) of bleeding, and 2 cases (4.0%) of fever. Following PTPBD with lithotriptic basket stone removal, abdominal pain occurred in 3 patients (6.0%) and fever in 2 (4.0%). Conclusion:PTPBD combined with lithotriptic basket in the second stage after PTCD under DSA is a minimally invasive treatment for large-diameter CBDS with safety and effectiveness.

Objective To investigate the clinical effect of digital subtraction angiography(DSA)-guided percutaneous transhepatic cholangial drainage(PTCD)in treatment of acute obstructive suppurative cholangitis(AOSC).Methods The relevant data of DSA-guided PTCD in treatment of AOSC patients were collected to analyze its safety and effectiveness.Results Among the 70 patients,there were 2 cases of bleeding,1 case of drainage tube blockage,and 1 case of drainage tube detachment,and no other serious surgical related complications occurred.The symptoms of 66 patients were improved from 3 to 7 d after PTCD compared with those before PTCD,and 4 patients died during hospitalization.The average daily bile drainage volume of patients was(650±130)m L,and the changes of leukocyte,total bilirubin,alanine aminotransferase and alkaline phosphatase indexes before and after surgery were statisti-cally significant(P<0.05).Conclusion DSA-guided PTCD in treatment of AOSC is a safe and effective minimally invasive method with high technical success rate,which can timely relieve obstruction,improve symptoms,reduce mortality,and create opportunities and conditions for secondary surgery or interventional therapy.

Concepts are the cornerstone of the development of disciplines. The concepts of TCM present that a superior concept contains more subordinate concepts. The superordinate concepts are often used to refer to different subordinate concepts, which can refer to both superior concepts themselves and non-specific subordinate concepts, that is, the characteristics of subordinate coverage and indefinite reference, which cause confusion in concept meaning, concept relationships, reasoning logic, and other problems. Nowadays, the TCM scholars pay little attention to this characteristic. Therefore, this article analyzed this characteristic, discussed its impact on the inheritance and development of TCM, and proposed that starting from the anchoring of concepts and entities to clarify the connotation of concepts, looking forward to provide new ideas for the definition of the concepts of TCM and the development of the discipline.

Objective:To explore the feasibility of obtaining three-dimensional (3D) models of intraosseous and periosteal arteries of hallux phalanx using micro-arteriography with micro-CT scan.Methods:From January 2022 to April 2025, the Department of Orthopaedic, the 988th Hospital of the Joint Logistics Support Force of the Chinese PLA conducted a study on 7 fresh-frozen specimens of distal lower limb (right lower limb) from an 85-year-old male, and both lower limbs from an 82-year-old male, a 78-year-old female and a 66-year-old male in the Department of Human Anatomy & Histology and Embryology, Peking University School of Basic Medical Sciences. Red lead oxide powder (Pb 3O 4) was ground and filtered through a 300 mesh, and then mixed with turpentine at ratios of 1 g ∶ 1.5 ml, 1 g ∶ 1.0 ml, and 1 g ∶ 0.5 ml to prepare lead-based contrast agent suspensions. After thawing the specimens at room temperature, the suspensions were injected via the popliteal artery in ascending order of concentration. After injections, the specimens were fixed in 10% methanal for 2 weeks. The proximal and distal phalanges of the hallux, with the surrounding periosteum preserved intact, were then harvested. The harvested specimens were scanned using micro-CT at an ultimate resolution of 12 μm. Subsequently, Mimics Medical software was used to reconstruct 3D models of the intraosseous and periosteal arteries within the phalanges. Results:Periosteal arteries in the proximal phalanx were primarily distributed near the joint region. A consistently large trunk artery entered from plantar side, supplying most of the diaphysis and head. There was a rich periosteal arterial network on both sides of the distal phalanx, which communicates with each other through the arterial arch in the bone groove. However, trunk intraosseous artery could be absent. Intraosseous arteries in the proximal ends of both the proximal and distal phalanges originated from periosteal arteries. These formed an interconnected arteriosomes and coursed parallel to the articular surfaces.Conclusion:The micro-arteriography acquired by micro-CT scan effectively visualizes intraosseous and periosteal arteries and enables the reconstruction and analysis of 3D models of the arteriosomes. The characteristics of arteriolar distribution provide a theoretical basis for osteotomy or internal fixation procedures involving a hallux phalanx.

Objective:To compare the efficacy and safety of continuous venetoclax combined azacitidine (VA) chemotherapy and intermedium/high-dose cytarabine (I/HDAC) consolidation in patients with acute myeloid leukemia (AML) fit for standard chemotherapy (transform from UNFIT) .Methods:Clinical data of patients who were fit for standard chemotherapy were collected among those with AML who underwent VA induction in the Department of Hematology, the Second Hospital of Hebei Medical University. The overall survival (OS), relapse-free survival (RFS), event-free survival (EFS), and incidence of adverse events were analyzed retrospectively.Results:This study enrolled 69 patients, consisting of 46 cases in the VA group and 23 cases in the I/HDAC group. We revealed the following. ① The median OS, RFS, EFS were 26.18, 24.69, 20.34 months in the VA group, and 34.14, 30.99, 28.42 months in the I/HDAC group, respectively, with no statistically significant difference (all P>0.05). Median OS of patients who underwent I/HDAC consolidation with European Leukemia Net (ELN) favorable-risk, positive measurable residual disease (MRD), wild type FLT3, or IDH1/2 mutation was significantly longer than those who received VA ( P<0.05). ②Adverse events rate of grade 3 - 4 neutropenia, grade 3 - 4 thrombocytopenia, and bacteremia were significantly lower in the VA group than in the I/HDAC group ( P<0.05) . Conclusions:I/HDAC consolidation was more likely to help get survival benefits for patients with ELN favorable-risk, positive MRD, wild type FLT3, or IDH1/2 mutation. Continuous VA chemotherapy exhibited superior safety than I/HDAC consolidation.

Immune checkpoints include a series of receptor-ligand pairs that play a key role in the proliferation, activation, and immune regulatory responses of immune cells. Although immune checkpoint inhibitors (ICIs), such as programmed death protein 1 (PD-1) and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) have achieved good therapeutic effects in clinical practice, some patients still experience ineffective treatment and immune resistance. A large amount of evidence has shown that immune checkpoint proteins are related to cell metabolism during immune regulation. On the one hand, immune checkpoints connect to alter the metabolic reprogramming of tumor cells to compete for nutrients required by immune cells. On the other hand, immune checkpoints regulate the metabolic pathways of immune cells, such as phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) to affect the activation of immune cells. Based on a review of the literature, this article reviews the mechanisms by which PD-1, CTLA-4, T cell immunoreceptor with Ig and ITIM domains (TIGIT), T cell immunoglobulin and mucin domain-containing protein 3 (TIM-3), cluster of differentiation 47 (CD47), and indoleamine 2,3-dioxygenase 1 (IDO1) regulate cell metabolic reprogramming, and looks forward to whether targeting the ligand-receptor pairs of immune checkpoints in a "dual regulation" manner and inhibiting metabolic pathways can effectively solve the problem of tumor immune resistance.
