Glioma is the most common primary malignant tumor of the central nervous system in adults. Despite the standard treatment of surgery combined with radiotherapy and chemotherapy, the prognosis for high-grade glioma patients remains poor, highlighting the urgent need to further explore its pathogenesis and develop new therapeutic strategies. This article reviews the research progress in the field of glioma in China in 2024, covering tumorigenesis mechanisms, tumor immune microenvironment composition, advances in imaging techniques and novel imaging agents, improvements in surgical approaches, mechanisms of radio- and chemoresistance, and explorations of new therapeutic modalities. These studies provide a solid theoretical foundation for advancing clinical diagnosis and treatment of gliomas and may offer new opportunities to improve patient outcomes.

Objective To investigate the relationship between ferroptosis-related genes[heme oxygenase-1(HO-1),solute carrier family 7 member 11(SLC7A11),and long-chain acyl-coenzyme A synthetase 4(ACSL4)]expression and cardiovascular events in patients with chronic renal failure(CRF),aiming to pro-vide clinical insights for risk assessment of cardiovascular complications.Methods A total of 124 CRF pa-tients(CRF group)admitted to the hospital from January 2020 to January 2023 and 124 healthy people(con-trol group)who underwent physical examination in the hospital during the same period were selected as the research objects.The levels of ferroptosis-related gene HO-1,SLC7A11 and ACSL4 were detected and com-pared between the two groups.CRF patients were followed up for 12 months after discharge,and they were di-vided into concurrent group(n=56)and non-concurrent group(n=66)according to the occurrence of cardio-vascular events.Spearman correlation analysis was used to investigate the correlation between iron death relat-ed genes HO-1,SLC7A11,ACSL4 and cardiovascular events in CRF patients.Univariate and multivariate Lo-gistic regression analysis were used to investigate the influencing factors of cardiovascular events in CRF pa-tients.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of iron death re-lated genes HO-1,SLC7A11,and ACSL4 for cardiovascular events in CRF patients.Results Serum HO-1 and SLC7A11 levels in CRF group were lower than those in control group(P＜0.05),and the ACSL4 level was higher than that in control group(P＜0.05).The serum HO-1 and SLC7A11 levels in concurrent group were lower than those in non-concurrent group(all P＜0.05),and the serum ACSL4 level was higher than that in non-concurrent group(P＜0.05).Ferroptosis-related genes HO-1 and SLC7A11 were negatively correlated with cardiovascular events(r=-0.708,—0.721,P＜0.05),while ACSL4 was positively correlated with car-diovascular events(r=0.699,P＜0.05).High serum ACSL4 expression and high cTnT level were risk fac-tors for cardiovascular events in CRF patients(P＜0.05),and high hemoglobin level and high serum HO-1 and SLC7A11 expression were protective factors for cardiovascular events in CRF patients(P＜0.05).ROC curve analysis results showed that the area under the curve(AUC)of serum HO-1,SLC7A11,ACSL4,hemo-globin and cTnT alone for predicting cardiovascular events in CRF patients were 0.787,0.735,0.773,0.651 and 0.782,respectively.The AUC of the combined prediction of ferroptosis-related genes was 0.837,and the AUC of the combined application of five factors was 0.880.According to Delong's test,the AUC of both com-bined application models was significantly higher than those of individual application(P＜0.05).The nomo-gram model showed that all ferroptosis-related genes were positively expressed(HO-1＜1.5,SLC7A11＜1.15,ACSL4≥2.75),and the risk of developing concurrent cardiovascular events in CRF patients could reach over 75％.Conclusion The expression of serum HO-1 and SLC7A11 in CRF patients is decreased,and the ACSL4 expression is increased,which is closely related to cardiovascular events,and the combined detection of three indexes has high value in predicting cardiovascular events in CRF patients.

Breast cancer remains a substantial threat to women's health and is one of the most prevalent malignant tumors in women.Because breast cancer onset is closely associated with female physiological characteristics,this article proposes that breast cancer be classified as a"women's miscellaneous diseases"and that its treatment be explored from this perspective.Drawing from Chapter 8 on Golden Chamber of Prescriptions for Miscellaneous Diseases in Women of Synopsis of Golden Chamber,the initial pathogenesis of breast cancer is associated with"emotional stress,improper lifestyle,deficiency,cold,and stagnation."The fundamental mechanism behind its formation is"blood cold accumulation and hardened masses."Specifically,emotional imbalance and improper lifestyle habits contribute to the combined invasion of the uterus by"deficiency,""accumulated cold,"and"stagnant qi."Over time,"cold-blood stasis accumulates at the uterine ostium,"and the cold and the stasis ascends from the uterus along the thoroughfare and conception vessels,obstructing the breast collaterals.This combination of yang qi stagnation and yin cold congealment,ultimately leads to the development of breast cancer.The treatment principle should focus on"activating yang and dispersing cold."A therapeutic approach centered on Wenjing Decoction combined with Xiaoyao Powder can be adapted based on the stage and type of breast cancer while also considering the dynamic interplay between pathogenic factors and healthy qi,along with shifts in deficiency and excess patterns of disease.By adhering to the principles of consistency and flexibility and integrating disease and syndrome differentiation,the goal is to develop precise and personalized treatment strategies to improve clinical outcomes.

Dengue fever, caused by of dengue virus (DENV) infection, is one of the most prevalent arboviral infections worldwide. It is estimated that approximately 390 million people are infected with DENV each year, of whom approximately 96 million will develop clinical symptoms and one in every twenty people may develop severe dengue leading to shock, internal bleeding and death. DENV includes four serotypes (1-4), each of which can cause various forms of disease. There is currently no specific treatment for dengue fever, and only two vaccines have been approved for use in some countries: CYD-TDV and TAK-003. CYD-TDV, which is suitable for people aged 9-45, can be affected by antibody-dependent enhancement (ADE), leading to more severe infections. Therefore, how to reduce or eliminate ADE becomes an important issue in current dengue vaccine research. In addition, the effects of DENV non-structural proteins on the immune system cannot be ignored. Currently, at least seven dengue vaccines are in various stages of development and clinical trials. This review will focus on three vaccine candidates that have made significant progress, and summarize the ways to avoid ADE the progress in the development of dengue vaccines using non-structural proteins as immunogens.

Objective To investigate the expression of PLCD3 mRNA in the synovium of osteoarthritis(OA)and its relationship with immune cell infiltration.Methods Based on the differentially expressed genes of OA found in the previous study,the expression of phospholipase Cδ3(PLCD3)mRNA was detected by col-lecting synovial samples from OA group and control group.CIBERSORT algorithm was used to analyze the infiltration pattern of immune cells in OA group and control group,and the correlation between PLCD3 and infiltrating immune cells was further analyzed.Results Compared with the control group,the relative expres-sion level of PLCD3 mRNA was significantly increased in synovial samples of OA group(P<0.05).The pro-portions of B cells naive,NK cells activated,M2 macrophages and mast cells activated in synovial tissues of OA group were relatively high(P<0.05).PLCD3 was positively correlated with the proportion of these four immune cells(P<0.05).Conclusion PLCD3 may be a key biomarker for the diagnosis of OA,which may be involved in the pathogenesis of OA by interacting with infiltrating immune cells.

OBJECTIVE: To investigate the regulatory role of the long non-coding RNA LINC00926 in pyroptosis of hypoxia-induced human umbilical vein vascular endothelial cells (HUVECs) and explore the molecular mechanism. METHODS: HUVECs were transfected with a LINC00926-overexpressing plasmid (OE-LINC00926), a siRNA targeting ELAVL1, or both, followed by exposure to hypoxia (5% O2) or normoxia. The expression of LINC00926 and ELAVL1 in hypoxia-treated HUVECs was detected using real-time quantitative PCR (RT-qPCR) and Western blotting. Cell proliferation was detected using Cell Counting Kit-8 (CCK-8), and the levels of IL-1β in the cell cultures was determined with ELISA. The protein expression levels of pyroptosis-related proteins (caspase-1, cleaved caspase-1 and NLRP3) in the treated cells were analyzed using Western blotting, and the binding between LINC00926 and ELAVL1 was verified with RNA immunoprecipitation (RIP) assay. RESULTS: Exposure to hypoxia obviously up-regulated the mRNA expression of LINC00926 and the protein expression of ELAVL1 in HUVECs, but did not affect the mRNA expression of ELAVL1. LINC00926 overexpression in the cells significantly inhibited cell proliferation, increased IL-1β level and enhanced the expressions of pyroptosis-related proteins (all P < 0.05). LINC00926 overexpression further up-regulated the protein expression of ELAVL1 in hypoxia-exposed HUVECs. The results of RIP assay confirmed the binding between LINC00926 and ELAVL1. ELAVL1 knockdown significantly decreased IL-1β level and the expressions of pyroptosis-related proteins in hypoxia-exposed HUVECs (P < 0.05), while LINC00926 overexpression partially reversed the effects of ELAVL1 knockdown. CONCLUSION LINC00926 promotes pyroptosis of hypoxia-induced HUVECs by recruiting ELAVL1.

Objective:To explore the role of navigation-assisted valgus stress method in avoiding excessive correction of lower limb mechanical axis after high tibial osteotomy (HTO).Methods:A retrospective study was carried out on osteoarthritis (OA) patients who were treated with HTO for medial compartment pain of knee from January 2020 to March 2022 in the Department of Joint Surgery, Shanghai Changhai Hospital, the First Affiliated Hospital of Naval Medical University. According to the different ways of confirming alignment during operation, they were divided into computer navigation assisted valgus stress HTO group (referred to as navigation group) and traditional rod fluoroscopy HTO group (referred to as traditional group). There were 28 patients in the navigation group, 10 males and 18 females, with age of 54.4±9.1 years (range, 41-73 years) and body mass index of 26.1±3.3 kg/m 2 (range, 19.8-35.2 kg/m 2); There were 30 patients in the traditional group, 13 males and 17 females, aged 56.9±8.5 years (range, 40-70 years), with a body mass index of 25.7±4.0 kg/m 2 (range, 19.2-32.9 kg/m 2). Measuring the mechanical femoral tibial angle (mFTA), joint line convergence angle (JLCA), medial proximal tibial angle (MPTA), Lysholm score and Hospital for Special Surgery (HSS) score before operation and at the last follow-up of the two groups, and conduct statistical analysis. Results:Both groups were followed up. The follow-up time of navigation group and traditional group was 21.3±8.7 months and 22.5±7.6 months, respectively, with no significant difference ( t=0.53, P=0.596). There were significant differences between the two groups in the amount of mechanical axis correction (ΔmFTA) and the amount of bone correction (ΔMPTA) ( t=2.09, P=0.041; t=2.58, P=0.012), while there was no significant difference in ΔJLCA ( t=0.32, P=0.753). In the navigation group, there were 9 cases (32%) of undercorrection, 17 cases (61%) with acceptable alignment, and 2 cases (7%) with over correction, while in the traditional group, there were 5 cases (17%) with under correction, 13 cases (43%) with acceptable alignment, and 12 cases (40%) with over correction. There was significant difference in the distribution rate of alignment between the two groups ( P=0.012), and the rate of overcorrection in the navigation group was significantly lower than that in the control group (7% vs. 40%, P=0.005). The intra group correlation coefficient between the navigation correction mechanical axis and ΔmFTA was 0.787. There was no significant difference in Lysholm score and HSS score between the two groups before and after surgery (all P>0.05), and they were significantly improved after operation (all P<0.05). Conclusion:Navigation-assisted valgus stress method HTO is reliable, which can accurately achieve the target alignment, reduce the incidence of over correction, and obtain good clinical results.

Objective:To investigate the value of intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI) and texture analysis for predicting BRAF gene mutation in rectal cancer.Methods:The clinical diagnositic trial was conducted. The clinicopathological data of 36 rectal cancer patients who were admitted to the First People's Hospital of Shangqiu from January 2016 to June 2021 were collected. There were 28 males and 8 females, aged (50±4)years. All the 36 patients were confirmed by pathological examination. After genetic testing, 12 patients with BRAF mutant type of BRAF V600E mutation were allocated into the mutation group, and 24 patients with BRAF wild type were allocated into the non-mutation group. All patients underwent MRI scan before surgery, and IVIM related post-processing images were received by Function Tool post-processing software. Observation indicators: (1) consistency test between observers of IVIM para-meters and texture parameters; (2) comparison of IVIM parameters on MRI between the two groups; (3) comparison of texture parameters on MRI between the two groups; (4) diagnostic efficacy of IVIM and texture parameters. The intraclass correlation coefficient (ICC) was used to evaluate the consistency between observers, with ICC >0.80 as good consistency. The average values of para-meters with ICC >0.80 were included for further analysis. Measurement data with normal distribu-tion were represented as Mean± SD, and comparison between groups was analyzed by the indepen-dent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed by the chi-square test. Comparison of ordinal data was analyzed by the non-parameter rank sum test. The texture parameters were combined using the Logistic regression model. Receiver operating charac-teristic curve was used to analyze the predictive performance and calculate the sensitivity and specificity. Results:(1) Consistency test between observers of IVIM parameters and texture parameters: the ICCs between two observers of IVIM parameters including apparent diffusion coefficient, diffusion related coefficient, perfusion-related diffusion coefficient and perfusion-related parameter were 0.91, 0.90, 0.91, 0.89, respectively. The ICCs of texture parameters including the minimum value, the maximum value, the 10th percentile and the 25th percentile between two observers were <0.80 while the ICCs of texture parameters including mean value, the 50th percentile, the 75th percentile, the 90th percentile, energy, entropy, skewness and kurtosis between two observers were >0.80. (2) Comparison of IVIM parameters on MRI between the two groups: IVIM parameters of diffusion related coefficient and perfusion-related parameter on MRI were (0.70±0.13)×10 -3 mm 2/s and 0.39±0.30 for the mutation group, versus (0.79±0.12)×10 -3 mm 2/s and 0.17±0.10 for the non-mutation group, showing significant differences between the two groups ( t=-2.17, 2.46, P<0.05). (3) Comparison of texture parameters on MRI between the two groups: the texture parameters of mean value and energy on diffusion related coefficient image were 0.54±0.23 and 0.00(0.00,0.01) for the mutation group, versus 0.77±0.34 and 0.01(0.00,0.01) for the non-mutation group, showing significant differences between the two groups ( t=-2.12, Z=-1.35, P<0.05). (4) Diagnostic efficacy of IVIM and texture parameters: the areas under the curve (AUCs) of diffusion related coefficient, perfusion-related parameter, IVIM parameters combination, mean value of diffu-sion related coefficient image, energy value of diffusion related coefficient image, texture parameters combination were 0.69[95% confidence interval ( CI) as 0.52-0.84], 0.76(95% CI as 0.59-0.88), 0.79(95% CI as 0.62-0.91), 0.71(95% CI as 0.52-0.85), 0.79(95% CI as 0.62-0.91), 0.84(95% CI as 0.68-0.94), which were all lower than the AUC of IVIM and texture parameters combination as 0.92(95% CI as 0.79-0.99). Conclusions:IVIM parameters and texture parameters of MRI can non-invasively predict the mutation status of BRAF gene in rectal cancer. The combination of IVIM and texture parameters has a better predictive efficacy.

Acute gastrointestinal dysfunction is a common and important complication of sepsis. As no exiting formal definition and classification of gastrointestinal dysfunction, most of the treatment strategies for gastrointestinal dysfunction are not based on clinical evidence, but on their own clinical experience. Experts of traditional Chinese medicine, integrated traditional Chinese and Western medicine and Western medicine from various disciplines in Shanghai are organized by the Shanghai Society of Integrated Traditional Chinese and Western Medicine and the Emergency Department Branch of Shanghai Physicians Association. After repeated discussion, literature search and formulation of the outline, we developed consensus on gastrointestinal dysfunction secondary to sepsis with integrating Traditional Chinese Medicine and Western medicine by consulting extensively on clinical experts in the fields of emergency medicine, gastroenterology, general surgery, infectious medicine and traditional Chinese medicine, and holding several expert forums and consultation meetings. This clinical expert consensus focused on acute gastrointestinal injury (AGI) classification and inducer of sepsis. In this consensus, the common symptoms, diagnosis, classifications, treatment strategies and suggestions of acute gastrointestinal injury or dysfunction secondary to sepsis were explored from the aspect of both Traditional Chinese Medicine and Western medicine.
