Objective:To observe the expression of CD36 in hepatocellular carcinoma tissues and cell lines, and to investigate the effects of CD36 on the proliferation and migration abilities of human hepatocellular carcinoma cell lines and human hepatocellular carcinoma cell xenograft models in nude mice.Methods:Differences in the expression levels of CD36 transcripts in 371 hepatocellular carcinoma and paracancerous tissues were analyzed based on information from The Cancer Genome Atlas (TCGA) database. Cancer tissues and corresponding paracancerous tissues of 48 hepatocellular carcinoma patients who were diagnosed and underwent surgical treatment at the Affiliated Hospital of Yangzhou University from January 2019 to February 2021 were prospectively collected, and the levels of CD36 mRNA in the tissues were detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) method. Western blotting was used to detect CD36 protein levels in human hepatocellular carcinoma cell lines Huh7 and HCCLM3 and human normal liver cell line LO2. Plasmids containing CD36 interfering sequences and empty plasmids were transfected into Huh7 cells or HCCLM3 cells for sh-CD36 group and control group, respectively. The CCK-8 assay was used to detect the proliferation ability (expressed as absorbance value) of cells in each group at 0, 12, 24, 36, 48 and 60 h of culture, and the scratch healing assay and Transwell assay were used to detect the migration ability of cells in each group. The Huh7 cells of sh-CD36 group or control group were injected into the axillary subcutis of BALB/c nude mice, with 4 mice in each group, to construct nude mice models of human hepatocellular carcinoma xenografts; the long and short diameters of tumor were measured weekly after 1 week of inoculation, and the tumor volume was calculated. The nude mice were put to death after 5 weeks of inoculation, and the tumor specimens were collected and weighed; the tumor cell morphology was observed under the microscope, and the expressions of CD36 and Ki-67 proteins in the tumor tissues was detected by immunohistochemistry (IHC).Results:Analysis of the data from the TCGA database showed that the level of CD36 transcripts was higher in hepatocellular carcinoma tissues compared with that in paracancerous tissues (4.2±1.8 vs. 3.2±1.5, t = 2.28, P = 0.035). Tissues detection using qRT-PCR in 48 patients with hepatocellular carcinoma showed that the relative expression of CD36 mRNA in hepatocellular carcinoma tissues was higher than that in paracancerous tissues (0.76±0.26 vs. 0.48±0.23, t = 3.52, P < 0.001). Western blotting assay showed that CD36 protein level in Huh7 and HCCLM3 cells was higher than that in LO2 cells, which were (1.42±0.11) times and (1.68±0.16) times higher than LO2 cells, respectively (both P < 0.001). At the mRNA and protein levels, the CD36 of Huh7 and HCCLM3 cells in the sh-CD36 group was lower than that in the corresponding control group (both P < 0.001). CCK-8 assay showed that the proliferative ability of Huh7 cells and HCCLM3 cells in the sh-CD36 group was lower than that in the corresponding control group after 36 and 24 h of culture (both P < 0.01). Scratch healing assay showed that the scratch healing rates of Huh7 cells [(12±3)% vs. (30±5)%, t = 4.01, P < 0.001] and HCCLM3 cells [(15±4)% vs. (29±5)%, t = 4.16, P < 0.001] in the sh-CD36 group were lower than those in the corresponding control group at 48 h of culture; Transwell assay showed that the number of Huh7 cells [(46±6) cells/field of view vs. (88± 6) cells/field of view, t = 5.56, P < 0.001] and HCCLM3 cells [(42±5) cells/field of view vs. (82±7) cells/field of view, t = 5.34, P < 0.001] penetrating into the membrane in 24 h in the sh-CD36 group was less than that in the corresponding control group. Five weeks after subcutaneous injection, the tumor volume [(682±268) mm 3vs. (1 375±512) mm 3, t = 4.73, P = 0.006] and tumor mass [(432±95) mg/mouse vs. (871±109) mg/mouse, t = 6.57, P < 0.001] of nude mice injected with Huh7 cells of the sh-CD36 group were lower than those of nude mice injected with Huh7 cells of the control group; under the microscope, the density of tumor cells in transplanted tumor specimens of nude mice injected with Huh7 cells of the sh-CD36 group was lower than that in nude mice injected with Huh7 cells of the control group, and the expression levels of both CD36 and Ki-67 proteins were also low. Conclusions:CD36 expression is up-regulated in cancer tissues of hepatocellular carcinoma patients and human hepatocellular carcinoma cell lines Huh7 and HCCLM3, and it may associate with cell proliferation and migration of hepatocellular carcinoma. Knockdown of CD36 expression significantly inhibits the proliferation and migration abilities of hepatocellular carcinoma cells in vitro, and inhibits the tumors of human hepatocellular carcinoma cell xenograft models in nude mice.

【Objective】 To investigate the development of adaptability in children aged 2 - 6, and to explore its influencing factors, so as to provide reference for promoting the development of adaptability in young children. 【Methods】 Data were from the National Nutrition and Health Systematic Survey for Children in China, and 3 319 children aged 2 - 6 and their parents from 28 sites across 14 provinces were recruited in this study.The Development Scale for Children Aged 0 - 6 years (WS/T 580-2017) was used to measure the developmental quotient of children′s adaptive ability, and a survey questionnaire was used to collect relevant information about children and their parents. 【Results】 Among 3 319 children aged 2 - 6, the proportion of slightly low or low level of adaptability, moderate adaptability development, good and excellent adaptability development was 7.68%,66.25% and 26.06%, respectively.The proportion of children aged 5 - 6 with good and excellent adaptability was lower in 3-year-old and 4-year-old groups (χ²=59.29, P<0.05).Multiple stepwise linear regression showed that children′s gender (β=0.06), gestational age of birth (β=-0.05), only child (β=-0.04), left-behind child (β=-0.04), the main caregiver (β=-0.06), and the education level of parents (β=0.09, 0.10), whether parents actively pay attention to children′s emotions (β=-0.06) and whether children play with homemade toys (β=-0.04) were the influencing factors of children′s adaptive development quotient.Girls, full-term children, only children, non-left-behind children, children with parents as main caregivers, parents with a high level of education, parents who often take the initiative to pay attention to children′s emotions, and children who play with homemade toys had a higher level of adaptability development quotient. 【Conclusions】 The development level of adaptability in children aged 2 - 6 in China is mostly above the average level and is related to multiple factors.Targeted intervention work can be carried out on relevant factors in order to promote the development of children′s adaptability.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Objective:To investigate the clinical, radiological, and pathological features of anaplastic gangliogliomas (AGGs) and to determine whether these tumors represent a distinct entity.Methods:Consecutive 667 cases of ganglioglioma (GG) diagnosed at the Xuanwu Hospital, Capital Medical University, Beijing, China between January 2015 and July 2023 were screened. Among these cases, 9 pathologically confirmed AGG cases were identified. Their clinical, radiological, treatment, and outcome data were analyzed retrospectively. Most of the tumor samples were subject to next-generation sequencing, while a subset of them were subject to DNA methylation profiling.Results:Among the 9 patients, there were five males and four females, with a median age of 8 years. Epileptic seizures (5/9) were the most frequently presented symptom. Radiological examinations showed three types of radiological manifestations: four cases showed abnormal MRI signals with no significant mass effects and mild enhancement; two cases demonstrated a mixed solid-cystic density lesion with peritumoral edema, which showed significant heterogeneous enhancement and obvious mass effects, and one case displayed cystic cavity formation with nodules on MRI, which showed evident enhancements. All cases exhibited mutations that were predicted to activate the MAP kinase signaling pathway, including seven with BRAF p.V600E mutation and two with NF1 mutation. Five AGGs with mutations involving the MAP kinase signaling pathway also had concurrent mutations, including three with CDKN2A homozygous deletion, one with a TERT promoter mutation, one with a H3F3A mutation, and one with a PTEN mutation.Conclusions:AGG exhibits a distinct spectrum of pathology, genetic mutations and clinical behaviors, differing from GG. Given these characteristics suggest that AGG may be a distinct tumor type, further expansion of the case series is needed. Therefore, a comprehensive integration of clinical, histological, and molecular analyses is required to correctly diagnose AGG. It will also help guide treatments and prognostication.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To screen the differentially expressed genes (DEG) related to inflammatory response associated with the prognosis of colon cancer based on the bioinformatics approach, and to construct and validate a prognostic model for colon cancer.Methods:RNA sequencing and clinical data of 472 colon cancer patients and normal colon tissues of 41 healthy people were retrieved from the Cancer Genome Atlas (TCGA) database. Gene expression related to prognosis of colon cancer and clinical data were retrieved from the International Cancer Genome Consortium (ICGC) database. The retrieval time was all from the establishment of library to November 2022. A total of 200 genes associated with inflammatory response obtained from the Gene Set Enrichment Analysis (GSEA) database were compared with the RNA sequencing gene dataset of colon cancer and normal colon tissues obtained from the TCGA database, and then DEG associated with inflammatory response were obtained. The prognosis-related DEG in the TCGA database were analyzed by using Cox proportional risk model, and the inflammatory response-related DEG were intersected with the prognosis-related DEG to obtain the prognosis-related inflammatory response-related DEG. The prognostic model of colon cancer was constructed by using LASSO Cox regression. Risk scores were calculated, and colon cancer patients in the TCGA database were divided into two groups of low risk (< the median value) and high risk (≥the median value) according to the median value of risk scores. Principal component analysis (PCA) was performed on patients in both groups, and survival analysis was performed by using Kaplan-Meier method. The efficacy of risk score in predicting the overall survival (OS) of colon cancer patients in the TCGA database was analyzed based on the R software timeROC program package. Clinical data from the ICGC database were applied to externally validate the constructed prognostic model, and patients with colon cancer in the ICGC database were classified into high and low risk groups based on the median risk score of patients with colon cancer in the TCGA database. By using R software, single-sample gene set enrichment analysis (ssGESA), immunophenotyping difference analysis, immune microenvironment correlation analysis, and immune checkpoint gene difference analysis of immune cells and immune function were performed for prognosis-related inflammation response-related DEG in the TCGA database.Results:A total of 60 inflammatory response-related DEG and 12 prognosis-related DEG were obtained; and 6 prognosis-related inflammatory response-related DEG (CCL24, GP1BA, SLC4A4, SRI, SPHK1, TIMP1) were obtained by taking the intersection set. LASSO Cox regression analysis showed that a prognostic model for colon cancer was constructed based on 6 prognosis-related inflammatory response-related DEG, and the risk score was calculated as = -0.113×CCL24+0.568×GP1BA+ (-0.375)×SLC4A4+(-0.051)×SRI+0.287×SPHK1+0.345×TIMP1. PCA results showed that patients with colon cancer could be better classified into 2 clusters. The OS in the high-risk group was worse than that in the low-risk group in the TCGA database ( P < 0.001); the area of the curve (AUC) of the prognostic risk score for predicting the OS rates of 1-year, 3-year, 5-year was 0.701, 0.685, and 0.675, respectively. The OS of the low-risk group was better than that of the high-risk group in the ICGC database; AUC of the prognostic risk score for predicting the OS rates of 1-year, 2-year, 3-year was 0.760, 0.788, and 0.743, respectively. ssGSEA analysis showed that the level of immune cell infiltration in the high-risk group in the TCGA database was high, especially the scores of activated dendritic cells, macrophages, neutrophils, plasmacytoid dendritic cells, T helper cells, and follicular helper T cells in the high-risk group were higher than those in the low-risk group, while the score of helper T cells 2 (Th2) in the high-risk group was lower compared with that in the low-risk group (all P < 0.05); in terms of immune function, the high-risk group had higher scores of antigen-presenting cell (APC) co-inhibition, APC co-stimulation, immune checkpoint, human leukocyte antigen (HLA), promotion of inflammation, parainflammation, T-cell stimulation, type Ⅰ interferon (IFN) response, and type ⅡIFN response scores compared with those in the low-risk group (all P < 0.05). The results of immunophenotyping analysis showed that IFN-γ-dominant type (C2) had the highest inflammatory response score, and the differences were statistically significant when compared with trauma healing type (C1) and inflammatory response type (C3), respectively (all P < 0.05). Immune microenvironment stromal cells and immune cells were all positively correlated with prognostic risk scores ( r values were 0.35 and 0.21, respectively, both P < 0.01). The results of immune checkpoint difference analysis showed there was a statistically significant difference in programmed-death receptor ligand 1 (PD-L1) expression level between high-risk group and low-risk group ( P = 0.002), and PD-L1 expression level was positively correlated with prognostic risk score ( r = 0.23, P < 0.01). Conclusions:Inflammatory response-related genes may play an important role in tumor immunity of colon cancer and can be used in the prognostic analysis and immunotherapy of colon cancer patients.

Objective: To explore trends in the asthma burden among Chinese children and adolescents 1-19 years old during 1990-2019. Methods: Based on data from the 2019 Global Burden of Disease Study, joinpoint regression was used to analyze the dynamic changes in the gender and age specific asthma burden, and the asthma burden in China was compared with countries that have different socio demographic indices(SDI). In addition, trends in asthma burden attributed to different risk factors were also investigated. Results: The asthma burden decreased slightly from 1990 to 1996 [annual percent change (APC)=-1.7%], then rapidly decreased from 1996 to 2005 (APC=-5.7%). The age standardized disability adjusted life years (DALYs) rate decreased from 158.55/100 000 to 88.59/100 000 in patients 1-19 years of age. From 2005 to 2017, the DALYs rate for asthma increased slowly, then rapidly. In 2017, the DALYs rate peaked at 176.18/100 000, then decreased to 126.79/100 000 in 2019. The burden of asthma in boys was higher than girls, and the DALYs rate for asthma in the group 5-9 years of age was higher than the remaining age groups. Furthermore, the age standardized DALYs rate for asthma among Chinese children and adolescents was relatively low among countries with a different SDI. In addition, the DALYs rate attributed to high body mass index increased in all age groups in China. Specifically, the average APC (AAPC) was 2.9% in group 1-4 years of age and the AAPC was 4.2% in the remaining age groups. The DALYs rate attributed to occupational asthmagens in the group 15-19 years of age decreased from 1990 to 2019 and the AAPC was -2.5%. Conclusion The asthma burden was relatively low among Chinese children and adolescents, and there were gender and age differences. The gender and age specific DALYs rate for asthma had a tendency to decrease, increase, then decrease. More attention should be paid to boys and the group 5-9 years of age, and strengthen the intervention of obesity and occupational asthmagens.

Objective: To explore the relationship between anemia and neuropsychological development in various domains among preschool children in China. Methods: Data came from the National Nutrition and Health Systematic Survey for children in China, and 3 261 preschool children aged 2-6 years and their parents from 28 sites across 14 provinces were recruited in this study. Parental and child characteristics were obtained by interview administrated questionnaires. Blood hemoglobin(Hb) concentration was determined by Hemocue method. Neuropsychological development quotients were assessed using the Development Scale for Children Aged 0-6 Years(WS/T 580-2017). Results: The average Hb level was (125.23±11.49)g/L and the overall anemia prevalence was 10.30% among preschool children. After adjusting the confounding factors(sex, age, ethnicity, region, feeding mode, maternal status during pregnancy, etc), developmental quotients of gross motor( β=-2.15, 95%CI =-3.89--0.41), fine motor( β=-2.46, 95%CI =-4.12--0.79), adaptive behavior( β=-2.59, 95%CI =-4.42--0.76), language( β=-3.65, 95%CI =-5.53--1.78), personal social behavior( β=-3.11, 95%CI =-4.94--1.28) and full scale( β=-2.79, 95%CI =-4.10--1.49) among children with anemia were significantly lower than non anemic infants( P <0.05). Conclusion Anemia was negatively associated with developmental quotient, as well as five domains of gross motor, fine motor, adaptive behavior, language, and personal social behavior in preschool children aged 2-6 years. It is suggested to carry out the work of anemia monitoring and intervention in preschool children to further improve their neuropsychological development.
