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.

BACKGROUND:Extracellular vesicles mediate intercellular signal transduction through the proteins,nucleic acids,and lipids they carry,thereby influencing the function of target cells.This vesicle-mediated communication mechanism is involved in regulating female reproductive development.OBJECTIVE:To summarize and analyze the regulatory roles of extracellular vesicle-mediated intercellular communication in female reproductive development.METHODS:A search was conducted in the PubMed database using the search terms"extracellular vesicles,exosomes,reproduction,maternal-embryo communication,maternal-fetal crosstalk,embryo implantation,endometrium,oviduct,follicle."The initial screening was carried out by reading the titles and abstracts of the literature,and then the literature with poor relevance to the research purpose,outdated content,and duplication was excluded according to the inclusion and exclusion criteria.Ultimately,69 relevant articles were included for comprehensive analysis.RESULTS AND CONCLUSION:Extracellular vesicles play a crucial role in key processes of female reproductive development,from folliculogenesis to implantation.(1)Extracellular vesicles mediate intercellular communication within the follicle,particularly the interactions between oocytes and follicular cells,which are essential for follicle development and maturation.(2)Extracellular vesicles and their contents facilitate interactions between the embryo and the fallopian tube,influencing the trajectory of embryonic development.(3)Extracellular vesicles and their contents promote implantation by mediating bidirectional communication between the embryo and the endometrium.Uterine-derived extracellular vesicles regulate processes such as embryo adhesion,invasion,and decidualization,while embryo-derived extracellular vesicles modulate endometrial receptivity,convey embryonic signals,and adjust the endometrial microenvironment.Studying the roles of extracellular vesicles in female reproductive development can provide valuable insights into the mechanisms of infertility and support the development of new therapeutic strategies.

BACKGROUND:Previous studies of the research group have found that icariin-containing serum can delay the progression of knee osteoarthritis,promote chondrocyte proliferation and stem cell cartilage differentiation in rats,but there is still a lack of sufficient basis for clinical application.OBJECTIVE:To investigate the repair effect of icariin-containing serum on lipopolysaccharide-induced inflammatory damage of human chondrocytes.METHODS:The effect of icariin-containing serum on chondrocyte viability was detected by cell counting kit-8 method,and the optimal volume fraction and time of icariin-containing serum were screened.The cells were then divided into blank group,lipopolysaccharide group,icariin-containing serum group and lipopolysaccharide+icariin-containing serum group.After grouping,immunofluorescence was used to detect the secretion of type Ⅱ collagen in chondrocytes in each group.Real-time PCR was used to detect the expression of related genes.RESULTS AND CONCLUSION:(1)Icariin-containing serum showed good biosafety characteristics for human chondrocytes,and the cell viability reached the highest level after 48 hours of intervention when the icariin-containing serum volume fraction was 15％,and the follow-up experiments were carried out according to the conditions.(2)Compared with the blank group,lipopolysaccharide significantly inhibited the expression of type Ⅱ collagen in chondrocytes,while icariin-containing serum showed a positive mobilization effect,which could effectively promote the secretion of type Ⅱ collagen in chondrocytes under normal and inflammatory conditions.(3)The mRNA expression of type Ⅱ collagen and Aggrecan in chondrocytes decreased significantly under lipopolysaccharide stimulation,and the mRNA expression levels of matrix metalloproteinase 13 and a disintegrin-like and metalloproteinase with thrombospondin motifs-5 increased significantly.Icariin-containing serum promoted the mRNA expression of type Ⅱ collagen in human chondrocytes under inflammatory conditions and reduced the mRNA expression of matrix metalloproteinase 13 and a disintegrin-like and metalloproteinase with thrombospondin motifs-5 in chondrocytes after lipopolysaccharide intervention.Therefore,these findings indicate that the icariin-containing serum has good safety for human chondrocytes and plays an important role in maintaining the normal physiological functions of chondrocytes,promoting the synthesis of extracellular matrix,and inhibiting the secretion of inflammatory factors.

OBJECTIVE:Postoperative recurrence is a common complication of percutaneous endoscopic lumbar discectomy for lumbar disc herniation,which can significantly increase the risk of reoperation.A well-performing risk prediction model can help identify high-risk groups early and prevent postoperative recurrence.This study systematically evaluated the risk prediction model for postoperative recurrence after percutaneous endoscopic lumbar discectomy to provide a reference for surgical decision-making.METHODS:The PubMed,Embase,Web of Science,CNKI,WanFang Data,VIP,and CBM were electronically searched to collect studies on the recurrence risk prediction models after percutaneous endoscopic lumbar discectomy from inception to July 1,2024.Two reviewers independently screened the literature and extracted data.The models' risk of bias,applicability,and report quality were assessed using prediction model risk of bias assessment tool(PROBAST)and Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis(TRIPOD)tools,respectively.Meta-analysis of postoperative recurrence rate of percutaneous endoscopic lumbar discectomy and related predictors was performed using Revman 5.4 software.RESULTS:(1)A total of 15 studies were included,all of which were retrospective studies,including 24 models for predicting the risk of recurrence after percutaneous endoscopic lumbar discectomy.(2)The PROBAST evaluation results indicated that all 15 studies exhibited a high risk of bias.Regarding applicability,two studies demonstrated a low risk,while 13 presented a high risk.(3)Regarding the TRIPOD reporting quality,the overall quality across the 15 studies was low.The primary reasons for this low compliance included the failure to report blinding,a lack of explanation for the sample size calculation method,lack of detailed description of missing data processing methods,and lack of information such as introduction to the model used.(4)Furthermore,the area under the receiver operating characteristic curve for the model ranged from 0.684 to 0.972,with the number of potential predictor variables varying from 15 to 28.(5)The results of meta-analysis showed that the postoperative recurrence rate of lumbar disc herniation patients treated with percutaneous endoscopic lumbar discectomy was 12％(95％CI=9.0％-15.0％),Modic changes(OR=6.72,95％CI=3.90-11.59),body mass index(OR=1.28,95％CI=1.10-1.49),work intensity(OR=3.22,95％CI=1.85-5.59),age(OR=2.28,95％CI=1.50-3.48),and smoking history(OR=2.65,95％CI=1.75-4.00)were independent influencing factors for postoperative recurrence of percutaneous endoscopic lumbar discectomy(all P＜0.05).CONCLUSION:The overall predictive performance of the recurrence risk prediction models after percutaneous endoscopic lumbar discectomy is satisfactory;however,the model exhibits a high overall risk of bias and applicability,coupled with low reporting quality.Additionally,there is a lack of prospective research and external validation.Future,risk prediction models should consider factors such as Modic changes,body mass index,work intensity,age,and smoking history as potential predictors.

Objective To investigate the features of non-motor symptoms and transcranial substantia nigra ultrasound in essential tremor （ET）. Methods General data were collected from 50 patients with ET and 50 healthy controls，and non-motor symptom scales and transcranial nigra sonography （TCS） were used for assessment. The t-test，the non-parametric test，and the chi-square test were used for comparison of general data，scale assessment results，and TCS findings between the two groups. Results There were significant differences between the ET group and the healthy control group in the total scores of NMSS，MoCA，HAMA，HAMD，PSQI，ESS，and FSS and the incidence rates of cognitive impairment，moderate or severe anxiety，poor sleep，and daytime sleepiness，while there were no significant differences in the incidence rates of moderate or severe depression and fatigue between the two groups. There were no significant differences between the two groups in terms of “hyperechoic area of the left side” “hyperechoic area of the right side” “hyperechoic area of both sides” “S/M value” “the number of cases with a hyperechoic area of >0.2 cm2 for at least one side” “the number of cases with an S/M ratio of >7%” and “the number of cases with positive TCS results”. Conclusion Compared with healthy controls，ET patients are more susceptible to cognitive impairment，anxiety，depression，poor sleep quality，daytime sleepiness，and fatigue，and the non-motor symptoms of ET should be taken seriously in clinical practice. TCS examination has a relatively low diagnostic value in ET patients and healthy individuals.

Objective:To investigate the current status of breast reconstruction after breast cancer surgery in hospitals in China.Methods:This study was a cross-sectional study using convenience sampling. A self-designed survey questionnaire was used to investigate nurses of department of breast diseases in China from May to August 2023. The content of the questionnaire included four aspects: identification information, basic hospital information, the implementation situation of breast reconstruction after breast cancer surgery, and the situation of medical and nursing human resources for breast reconstruction, with a total of 39 items. Statistical analysis was performed using SPSS 26.0 software. The non-normally distributed measurement data were expressed as M( Q1, Q3), and the Mann-Whitney U test was used for comparison between groups. Numeric data were expressed as frequency and percentage, and comparisons between groups were made using the χ2-test or Fisher’s exact probability method. P<0.05 indicated that the difference was statistically significant. Results:A total of 212 public hospitals from 31 provinces, autonomous regions and municipalities participated in the survey. Two hundred and three hospitals (95.8%) returned valid data, including 155 Grade Ⅲ Level A hospitals, 19 Grade Ⅲ Level B and C hospitals, and 29 Grade Ⅱ hospitals. There were 157 general hospitals, 32 specialized cancer hospitals, and 14 other hospitals. Thirty-nine hospitals did not perform breast reconstruction surgery. A total of 164 hospitals (80.8%) had already carried out breast reconstruction surgery, among which the proportion of breast reconstruction in Grade Ⅲ Level A hospitals [90.3% (140/155)] was significantly higher than that in Grade Ⅲ Level B and C hospitals [52.6% (10/19)] and Grade Ⅱ hospitals [48.3% (14/29)] ( P<0.01). The proportion of breast reconstruction in specialized cancer hospitals [96.9% (31/32)] was significantly higher than that in general hospitals [79.0% (124/157)] and other types of hospitals [64.3% (9/14)] ( P<0.05). Among the 164 hospitals, 310 (150, 637.5) patients underwent breast cancer surgery and 30 (10, 100) patients underwent breast reconstruction in 2022. The proportion of patients undergoing breast reconstruction surgery among breast cancer surgery patients was 13.3% (4.0%, 20.0%). The number of patients receiving immediate breast reconstruction was 11 (2.5, 46.5) cases, and the number of those receiving delayed breast reconstruction was 5 (0, 18.5) cases. Among 203 hospitals, the median proportions of breast oncoplastic surgeons and specialized nurses among healthcare providers in breast surgery departments were 28.6% (2/7) and 75.0% (12/16), respectively. In comparison of the 164 hospitals offering breast reconstruction surgery and 39 hospitals not, the median numbers of breast oncoplastic surgeons were 3 (1, 8) versus 1 (0, 3), and qualified breast reconstruction nurses were 12 (6, 16) versus 1 (0, 8), respectively. All differences were statistically significant (all P<0.01). Conclusion:About 80% of hospitals in China have offered breast reconstruction procedures after breast cancer surgery, and the proportion of Grade Ⅲ Level A hospitals and specialized cancer hospitals is higher than that of other types of hospitals. The proportion of patients undergoing breast reconstruction after breast cancer surgery is relatively low, and there is a considerable potential of improvements. Breast oncoplastic surgeons and nurses are insufficient, so it is necessary to strengthen the training of specialized medical staff and improve surgical techniques and the level of nursing services simultaneously, so as to improve the quality of life of breast cancer patients.
