Objective: To systematically evaluate the association between maternal adverse childhood experiences (ACEs) and offspring social behavior, so as to provide a theoretical basis for further research on intergenerational social behavioral development. Methods: Relevant research literature about maternal ACEs and the development of children s maladaptive social behaviors were collected, from China National Knowledge Infrastructure (CNKI), VIP, Wanfang, SinoMed, PubMed, Web of Science, Cochrane Library, Embase and SpringLink databases, covering the period from the inception of each database to May 2025. The Chinese database matched and searched through three groups of keywords: "Pregnant women" "Mothers" and "Women"; "Bad childhood experience" "Bad early experience" and "Bad adolescent experience"; "Children" "Teenagers" "Children s behavior" "Children s development" "Teenagers behavior" "Internalized behavior" and "Externalized behavior". The English database was searched by three groups of keywords: "Female" "Pregnant women" "Mothers"; "Adverse childhood experiences" "Adverse early childhood experiences" "Adverse experiences of adolescent"; "Child behavior" "Child development" "Adolescent behavior" "Internalized behaviors" "Externalized behaviors". The selected literature was evaluated for quality and data extraction, with OR and 95% CI as effect indicators. Stata 16.0 software was used for heterogeneity testing, subgroup analysis, and publication bias analysis. Results: A total of 14 studies involving 64 302 mother-child pairs were included. The Meta analysis results showed a significant correlation between maternal ACEs and both offspring maladaptive internalized behaviors ( OR=1.75, 95%CI=1.42-2.15, P <0.01) and externalized behaviors ( OR=1.82, 95%CI=1.51-2.20, P <0.01). The results of subgroup analyses showed that in different regions[internalized behaviors:domestic, foreign OR (95% CI )=2.03(1.49-2.76), 1.55(1.19-2.03); externalized behaviors: domestic, foreign OR (95% CI )=2.41(1.52-3.82), 1.65(1.36-2.01)], study type[internalized behaviors: cohort study, cross sectional study OR (95% CI )=1.64(1.34-2.00), 1.85(1.30-2.65); externalized behaviors: cohort study, cross sectional study OR (95% CI )=1.76(1.46-2.12), 2.12(1.40-3.20)], sample size [internalized behaviors: ≥4 000, <4 000 pairs OR (95% CI )=1.69(1.13-2.55), 1.77( 1.41 -2.24); externalized behaviors: ≥3 000, <3 000 pairs OR (95% CI )=1.72(1.37-2.17), 2.13(1.44-3.15)], there were significant and positive association between mothers ACEs and children s internalizing and externalizing behaviors (all P <0.05). Conclusion A substantial positive association exists between maternal ACEs and the development of offspring maladaptive internalized and externalized behaviors, but the result needs to be continued to be validated by more research.

In the century-long evolution of insulin pharmaceuticals, each transformative advancement in this drug class has been closely tied to the ability to obtain new insulin isoforms for research. Despite this, the recently discovered naturally occurring isoforms of glycosylated human insulin have remained largely unattainable for proper characterization. Herein, we demonstrate for the first time that total chemical synthesis can be used to generate all isoforms. This achievement required maintaining the correct positions of the interchain disulfide bonds while effectively removing protecting groups on complex glycans. Notably, the availability of seven glycoforms reveals the important effects of natural sialylated glycans in suppressing insulin self-association and enhancing its solubility, surpassing the performance of currently employed rapid-acting insulin drugs. This work not only offers a readily adaptable platform for exploring natural O-glycosylation in other therapeutic proteins and peptides but also lays the groundwork for further research into harnessing natural glycosylation for therapeutic applications.

Objective To investigate the safety and feasibility of two-port laparoscopic full layer circular closure of the hernia ring for direct inguinal hernia.Methods Between September 2019 and February 2024,9 cases of pediatric indirect inguinal hernia were found to be accompanied by an occult direct inguinal hernia on the right side during two-port laparoscopic inner ring closure.After completing the high ligation of the indirect hernia under laparoscopic monitoring,the bottom of the direct hernia sac was investigated.The needle was held and inserted sequentially from the 4 o'clock direction,crossing the abdominal wall muscle layer through the peritoneum to the subcutaneous layer,and exited at the 8 o'clock direction.The same method was conducted from the 8 o'clock direction in and at the 12 o'clock direction out,and afterwards from the 12 o'clock direction in and at the 16 o'clock direction out(near the previous 4 o'clock insertion point),followed by knotting and closure of the hernia ring.Results Postoperative diagnosis indicated 3 cases of Pantalon hernia(right indirect hernia+right direct hernia)and 6 cases of left indirect hernia+right direct hernia.No extraperitoneal lipoma was found outside the hernia sac.Two-port laparoscopic high ligation of the indirect hernia and laparoscopic circular closure through muscle layer to subcutaneous layer of abdominal wall around the hernia ring was carried out.The operation time was(32.5±3.5)min,and blood loss was less than 1 ml.No intraoperative complications were seen.All the patients were discharged within 6 h after surgery and followed up for 5-13 months(mean,8 months),with 3 cases followed up for more than 12 months.No complications such as incision infection,recurrent hernia,hydrocele,iatrogenic cryptorchidism or testicular atrophy was found.Ultrasound examination of the direct hernia triangular area showed uniform thickness of the abdominal wall and no localized defects observed.Conclusions Laparoscopic circular closure through muscle layer to subcutaneous layer of abdominal wall around the hernia ring is safe and feasible.This procedure supplements the pediatric direct inguinal hernia repair procedure by suturing and closing both peritoneum and abdominal wall muscle layer of direct hernia defect without changing the normal anatomical position of the umbilical fold.

BACKGROUND:Topical administration of tranexamic acid can be used for anti-skin pigmentation,but its large polarity makes it difficult to break through the cuticle barrier and cell membrane when administered topically,and the subcutaneous accumulation concentration is not easy to reach the effective therapeutic concentration.OBJECTIVE:To design functionalized self-assembled micelles to enhance the anti-pigmentation effect of tranexamic acid.METHODS:The plant polyphenol derivative epigallocatechin gallate palmitate and metformin were used as carrier materials.The self-assembled micelles with synergistic anti-pigging activity and enhanced drug permeability were prepared by hydrogen bonding and electrostatic interaction.The nanoscale properties and stability of self-assembled drug-loaded micelles were tested,and their transdermal permeability was evaluated,and their biocompatibility and cellular effects were investigated.RESULTS AND CONCLUSION:(1)Functional self-assembled drug-carrying micelles with average particle size of(176.27±5.23)nm,polydispersity coefficient of 0.23±0.02,and the Zeta potential of(-25.67±0.98)mV had good stability.The mass concentrations of tranexamic acid and metformin in the self-assembled drug-carrying micelles were(20.03±0.12)and(6.67±0.08)mg/mL,respectively.The drug loadings of tranexamic acid and metformin in the self-assembled drug-carrying micelles were(19.97±0.12)％and(6.65±0.08)％,respectively.(2)In vitro transdermal results showed that the self-assembled drug-carrying micelles had higher penetration and intradermal retention per unit skin area,and could penetrate and diffuse to deeper parts of the skin.(3)MTT assay results demonstrated that undrug-loaded self-assembled micelles containing tranexamic acid 50-250 μg/mL had no toxic effects on mouse fibroblasts and mouse skin melanoma cells.The self-assembled drug-carrying micelles containing tranexamic acid 500 μg/mL had a slight toxic effect on mouse skin melanoma cells.The self-assembled drug-carrying micelles containing 50-500 μg/mL of tranexamic acid did not cause hemolysis and had good biological safety.(4)In vitro cell culture results showed that self-assembled drug-carrying micelles containing 500 μg/mL tranexamic acid could significantly inhibit the tyrosinase activity and melanin release of mouse skin melanoma cells,and the inhibitory effect was stronger than that of tranexamic acid solution or metformin solution alone.These results indicated that functionalized self-assembled micelles could synergize with tranexamic acid to inhibit tyrosinase activity,reduce melanin synthesis,and enhance the anti-skin pigmentation effect of tranexamic acid.

Objective To explore the traditional Chinese medicine(TCM)syndrome characteristics of patients with Chikungunya hemorrhagic fever and to provide empirical data to support the application of TCM in diagnosing and treating Chikungunya hemorrhagic fever.Methods A cross-sectional survey was conducted to collect clinical data(sex,age,days since onset,and comorbidity underlying disease conditions)and TCM with four-examination information(symptoms,tongue manifestations,and pulse manifestations)from 255 patients with Chikungunya hemorrhagic fever who visited Lecong Hospital of Shunde,Foshan,the Third People's Hospital of Shunde District of Foshan,Shunde Hospital of Southern Medical University Affiliated Chencun Hospital between July 23 and July 29,2025.Factor and cluster analyses were used to summarize TCM syndrome characteristics and analyze core pathogenesis in conjunction with clinical features.Results Among the 255 patients with Chikungunya hemorrhagic fever,131 were male and 124 were female,with a age of(49.05±17.93)years and a disease duration of(3.26±1.78)days.Among the four types of examination information in TCM,35 items exhibited a frequency exceeding 10%.The most prevalent symptoms were arthralgia(180 patients,70.59%),exanthem(153 patients,60.00%),fatigue(99 patients,38.82%),anhidrosis(98 patients,38.43%),pruritus(96 patients,37.65%),and fever(92 patients,36.08%).Tongue and pulse manifestations were primarily white fur(155 patients,60.78%),pink tongue(111 patients,43.53%),slippery pulse(143 patients,56.08%),and greasy fur(134 patients,52.53%).Patients with disease onset≤3 d had a higher incidence of arthralgia,fatigue,fever,aversion to cold,generalized muscle pain,aversion to wind,insomnia,headache,sweating,low-grade fever,poor appetite,loose stool,hyperhidrosis,and red tongue than those with disease onset≥4 d(P<0.05).Patients with disease onset≥4 d had a higher incidence of pink tongue and thick fur than those with disease onset≤3 d(P<0.05).The syndrome elements in patients with Chikungunya hemorrhagic fever predominantly manifested on the defensive exterior,with involvement of the sinew-bone joints,skin-muscle,and spleen.Pathogenic factors were primarily characterized by external winds,dampness,and heat.Factor and cluster analysis result indicated three TCM pathogenesis progression patterns:imbalance of the defensive exterior with wind-dampness conflict and heat transformation;dampness-heat flowing into muscles and meridians causing joint obstruction and qi blood stasis;and dampness-heat congelation resulting in qi mechanism obstruction,consumption of body fluids,and infiltration of the skin.Conclusion Patients with Chikungunya hemorrhagic fever primarily present with fever,joint pain,and rashes.In TCM,this condition falls under the category of"dampness-warmth"syndrome.Its etiology is attributed to pathogens,with transmission occurring through mosquito bites.The core pathogenesis of TCM is the invasion of the defensive exterior and dampness-toxic heat accumulation.The therapeutic principles focus on clearing heat pathogens,resolving dampness pathogens,dispersing wind pathogens,and promoting the resolution of rashes.

BACKGROUND:Previous studies have shown that Huosui Formula has a synergistic effect on the immune and hematopoietic regulation of patients with myelodysplastic syndrome,but the specific mechanism is not yet clear.OBJECTIVE:To explore the effect and mechanism of Huosui Formula on bone marrow hematopoiesis in rats with myelodysplastic syndrome.METHODS:A total of 70 SD rats were randomly divided into a normal control group(n=10),a model group(n=15),a western medicine group(n=15),a low-dose Huosui Formula group(n=15),and a high-dose Huosui Formula group(n=15).Except for the normal control group,the other four groups were injected with dimethyl benzanthracene via the tail vein to induce the establishment of rat myelodysplastic syndrome models.After modeling,the normal control group and the model group were given normal saline;the western medicine group was given thalidomide capsules 10 mg/kg and retinoic acid tablets 4 mg/kg,and the low-dose Huosui Formula group and the high-dose Huosui Formula group were given 1.5 and 6 g/kg Huosui Formula,respectively,by intragastric administration once a day for 28 consecutive days.Peripheral blood and femoral bone marrow tissue were collected to detect peripheral blood routine and bone marrow biopsy hematopoietic proliferation.Flow cytometry was used to detect T lymphocyte subsets and the expression of CTLA-4 and PD-1 on T lymphocytes.RESULTS AND CONCLUSION:(1)Compared with the normal control group,peripheral blood leukocyte,neutrophil,hemoglobin,platelet,and CD4+,CD4+/CD8+levels were decreased in the model group significantly(P＜0.05),while CD4+PD-1+,CD8+PD-1+,CD4+CTLA-4+,and CD8+CTLA-4+expressions were significantly upregulated(P＜0.05).(2)In all dosage groups,myelopoietic proliferation was increased compared with the model group,with no significant difference between the groups(P＞0.05).(3)Compared with the model group,leukocytes,hemoglobin,platelets,and CD4+,CD4+/CD8+were significantly elevated in the high-dose Huosui Formula group(P＜0.05),the expression of CD8+was significantly lower(P＜0.05),and the levels of CD4+PD-1+,CD8+PD-1+,CD4+CTLA-4+,and CD8+CTLA-4+were down-regulated but not statistically significant(P＞0.05).(4)The western medicine group and the high-dose Huosui Formula group showed similar efficacy.The improvement of each index in the high-dose Huosui Formula group was superior to that in the low-dose Huosui Formula group.These findings indicate that Huosui Formula can improve the bone marrow hematopoiesis in myelodysplastic syndrome model rats,increase the levels of CD4+,and CD4+/CD8+while down-regulate the expression levels of CD4+PD-1+,CD8+PD-1+,CD4+CTLA-4+,and CD8+CTLA-4+.These observations suggest a link to the negative immunoregulation mechanism.
