BACKGROUND:Bone tissue loss caused by tumors and trauma can have an adverse effect on postoperative rehabilitation.Therefore,scaffold materials are usually implanted during treatment.However,the existing implant materials are relatively simple and lack antibacterial properties.Early implantation may lead to iatrogenic autoinfection and have an adverse effect on osteogenesis.OBJECTIVE:To construct a KR-12-a5 polypeptide-nanohydroxyapatite-small intestinal submucosa composite scaffold and evaluate its feasibility as a material for promoting bone defect repair.METHODS:The small intestinal submucosa scaffold and the small intestinal submucosa scaffold containing 25,50,and 100 mg/mL nanohydroxyapatite(referred to as nHA-SIS scaffold)were prepared by 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride/N-hydroxysuccinimide cross-linking method.The appropriate scaffold was screened for subsequent experiments by mechanical property testing.The antibacterial properties of KR-12-a5 polypeptide solution against Staphylococcus aureus,Streptococcus gordonii,and Fusobacterium nucleatum were detected.The nHA-SIS scaffolds were immersed in 250,500,and 1 000 μg/mL KR-12-a5 peptide solutions for 24 hours,and then freeze-dried to obtain peptide-loaded nanohydroxyapatite-porcine small intestinal submucosa composite scaffolds(denoted as P-nHA-SIS scaffolds).The sustained-release properties of the three groups of scaffolds were characterized.The nHA-SIS scaffolds and the three groups of P-nHA-SIS scaffolds were co-cultured with Staphylococcus aureus,Streptococcus gordonii,and Fusobacterium nucleatum for 24 hours or 48 hours.The scaffolds with strong antibacterial ability were screened by live and dead bacteria staining and scanning electron microscopy for subsequent experiments.The degradation properties and water absorption rates of the uncross-linked small intestinal submucosa scaffolds,cross-linked small intestinal submucosa scaffolds,nHA-SIS scaffolds,and P-nHA-SIS scaffolds were characterized.The extracts of cross-linked small intestinal submucosal scaffolds,nHA-SIS scaffolds,and P-nHA-SIS scaffolds were co-cultured with MC3T3-E1 cells.CCK-8 assay and live-dead cell staining were performed.The effects of the extracts of the three scaffolds on the migration of MC3T3-E1 cells were detected by Transwell chamber assay.RESULTS AND CONCLUSION:(1)The elastic modulus and compressive strength of 25,50,and 100 mg/mL nHA-SIS scaffolds were higher than those of small intestinal submucosal scaffolds(P<0.05),among which the elastic modulus and compressive strength of 25 mg/mL nHA-SIS scaffolds were the highest,and this group of scaffolds were selected for subsequent experiments to load peptides.(2)KR-12-a5 peptide had strong antibacterial activity against common bacteria in bone defects(Staphylococcus aureus,Streptococcus gordonii,and Fusobacterium nucleatum).The three groups of P-nHA-SIS scaffolds all had sustained release properties.With the increase of peptide mass concentration,the antibacterial property of P-nHA-SIS scaffold was enhanced.Among them,the P-nHA-SIS scaffold loaded with 500 μg/mL peptide had achieved a satisfactory antibacterial effect,and this group of scaffolds would be selected in the future.(3)The degradation rate of the three groups of cross-linked scaffolds was lower than that of the uncross-linked scaffolds,and the water absorption rate was greater than that of the uncross-linked scaffolds.P-nHA-SIS scaffolds could promote the proliferation and migration of MC3T3-E1 cells without affecting the activity of MC3T3-E1 cells.(4)The results show that P-nHA-SIS scaffolds have strong antibacterial properties and the ability to promote the proliferation and migration of MC3T3-E1 cells,and are expected to be used in bone defect repair.

As the core vehicle for preserving and transmitting traditional Chinese medicine(TCM) academic thought and clinical experience, the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine, this study conducted a comprehensive analysis of critical challenges, including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic, encompassing three dimensions of authenticity and standardization, characteristics and advantages, application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment, while aligning with modern scientific research standards, achieving a balance between individualized TCM experience and standardized evaluation. Concurrently, this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases, contributing significantly to the inheritance of TCM knowledge, evidence-based practice, and the reform of talent evaluation mechanisms.

The contents of the female inguinal hernia include abdominal organs such as ovaries and fallopian tubes, and most of these are the result of sliding hernias. However, it is worth noting for surgeons specialized in hernia and abdominal wall surgery that there is a rare clinical diagnosis of hernia uterine inguinale, which is commonly seen in the Müllerian anomaly. Combined with relevant research progress at home and abroad, as well as the clinical experience in the diagnosis and treatment of patients with inguinal uterine hernia caused by Müllerian duct anomaly, the authors systematically introduce the clinical manifes-tations, key diagnosis and treatment points of female Müllerian duct anomaly in the inguinal region.

Objective:To analyze the effects of vitamin D supplementation therapy on the levels of serum total immunoglobulin E (IgE) and specific IgE (sIgE), as well as T lymphocyte subsets in children with atopic dermatitis (AD).Methods:A retrospective study was conducted. A total of 103 children with AD who visited the Dermatology Department of Xi'an Children's Hospital from January 2023 to December 2024 were selected as the research subjects. They were divided into an observation group 52 cases and a control group 51 cases according to the treatment methods. Children in both the control group and the observation group received treatment with levocetirizine oral solution, and the observation group additionally received oral treatment with vitamin D drops. The general clinical data and clinical efficacy were compared between the two groups of children. The characteristics and differences of serum IgE (total IgE, sIgE of inhaled allergens, sIgE of ingested allergens) and T lymphocyte subsets [regulatory T lymphocyte (Treg cell), helper T lymphocyte 17 (Th17 cell), Th17 cell/Treg cell] before and after treatment were evaluated. The Pearson correlation coefficient was used to test the correlations among the observed indicators.Results:After treatment, the total effective rate in the observation group was higher than that in the control group: 92.3% (48/52) vs. 78.4% (40/51), with a statistically significant difference ( P<0.05). After treatment, the levels of serum total IgE, sIgE of inhaled allergens and sIgE of ingested allergens in the observation group were lower than those in the control group: (174.93 ± 18.78) kU/L vs. (194.04 ± 19.87) kU/L, (93.07 ± 17.52) kU/L vs. (101.38 ± 19.80) kU/L, (74.21 ± 16.11) kU/L vs. (86.20 ± 14.72) kU/L, with statistically significant differences ( P<0.05). After treatment, the Treg cell in the observation group was higher than that in the control group: (5.46 ± 0.41)% vs. (4.42 ± 0.24)%, while the Th17 cell and Th17 cell/Treg cell were both lower than those in the control group: (1.78 ± 0.30)% vs. (2.26 ± 0.25)%, 0.33 ± 0.06 vs. 0.51 ± 0.06, and the differences were statistically significant ( P< 0.05). Among all the enrolled children, after treatment, the total IgE ( r = - 0.48, P<0.001), sIgE of inhaled allergens ( r = -0.24, P = 0.016) and sIgE of ingested allergens ( r = - 0.32, P = 0.001) were negatively correlated with the Treg cell. The total IgE ( r = 0.38 and 0.50, P<0.001) and sIgE of ingested allergens ( r = 0.24 and 0.32, P = 0.013 and 0.001) were positively correlated with the Th17 cell and the Th17 cell/Treg cell. Conclusions:Vitamin D supplementation therapy can effectively reduce total IgE and sIgE levels in children with AD. Concurrently, it can ameliorate the Th17 cell/Treg cell imbalance, ultimately leading to improved treatment outcomes and prognosis for these children.
