Objective To assess the potential role of disulfidptosis-related genes (DRGs) in pan-cancer on prognosis and immunity on the basis of bioinformatics approaches. Methods Pan-cancer RNA-seq data, mutation profiles, clinical information, TMB, MSI, stemness scores, and tumor and immune microenvironment data contained in TCGA and various open-source online databases, and multi-group R-language algorithms were used for comprehensive analysis. The expression levels of DRGs at the cellular level were experimentally validated using qPCR. Results LRPPRC, NCKAP1, NDUFS1, and NUBPL had a better prognosis in renal clear cell carcinoma (P<0.001), whereas SLC7A11, NCKAP1, and SLC3A2 had a worse prognosis in hepatocellular carcinoma (P<0.001). TME analysis showed that LRPPRC was negatively correlated with immune cells, stromal cells, and estimated scores in all tumor types. TMB analysis revealed the potential research value of DRGs for PD-1/PD-L1 therapy in pan-cancer. Drug sensitivity analysis showed that SLC7A11 (r=0.454), SLC3A2 (r=0.366), and NCKAP1 (r=0.455) were significantly associated with Kahalide F (P<0.01). Experimental validation demonstrated the overall higher expression levels of GYS1 and NCKAP1 than normal cells in lung adenocarcinoma, colon adenocarcinoma, esophageal squamous carcinoma, and hepatocellular carcinoma (P<0.05). Conclusion Pan-cancer analysis of DRGs indicates that DRGs may serve as important biomarkers for the diagnosis and prognosis of renal clear-cell carcinoma, lung adenocarcinoma, and hepatocellular carcinoma.

BACKGROUND:The reasonable implantation range of femoral prosthesis in unicompartmental knee arthroplasty in patients with osteoporosis has not been investigated,and previous studies have often been based on unicompartmental knee arthroplasty models in normal bone,with fewer mechanical studies in models with non-normal bone.Complications after unicompartmental knee arthroplasty have been shown to be highly associated with osteoporosis. OBJECTIVE:To analyze the biomechanical effects of the coronal inclination of the Sled fixed platform femoral prosthesis on unicompartmental knee arthroplasty in patients with osteoporosis and to find the correlation between osteoporosis and mid-and long-term complications after unicompartmental knee arthroplasty. METHODS:Based on the digital imaging technology to obtain the data of the knee joint and prosthesis,a normal bone knee model is then created by using specialized software such as Mimics and Geomagic studio.Based on a validated normal bone knee model,an osteoporotic knee model was created by changing the material parameters.Totally 14 unicompartmental knee arthroplasty finite element models were created using Sled fixed platform femoral prosthesis:standard position(0°),varus and valgus angles:3°,6°,9° in the normal bone and osteoporosis groups.Stress changes on the surface of polyethylene liner,cancellous bone under tibial prosthesis,and cortical bone were calculated and analyzed in all unicompartmental knee arthroplasty models. RESULTS AND CONCLUSION:(1)In the osteoporotic models,the high stress values of the polyethylene liner surface and the cancellous bone under the tibial prosthesis increased with the increase of the tilt angle of the femoral prosthesis,and the high stress values of the cortical bone surface under the tibial prosthesis increased with the increase of the prosthesis valgus angles and decreased with the increase of the varus angles.(2)For the polyethylene liner surface as well as the subcortical bone surface of the tibial prosthesis,the high stress values of the models for each inclination angle in the osteoporosis group were greater than those of the corresponding models in the normal bone group.For the surface of the cancellous bone under the tibial prosthesis,the high stress values of the tilt angle models of the osteoporosis groups were smaller than those of the normal bone groups.(3)Osteoporosis may cause biomechanical abnormalities in the internal structures of the knee after unicondylar replacement,increasing the potential risk of postoperative aseptic loosening of the prosthesis and periprosthetic fractures.Varus and valgus of the femoral prosthesis in the coronal plane should be avoided as much as possible when performing medial unicompartmental knee arthroplasty with a Sled fixation platform in osteoporotic knees.

[Objective] To study the relationship between the expression intensity of HLA-Ⅰ platelet antibodies in patients with platelet transfusion refractoriness (PTR) and platelet cross-matching, and to further evaluate other factors in order to provide relevant data support for improving platelet transfusion efficiency and optimizing platelet transfusion regimens. [Methods] Luminex single antigen flow cytometry was used to detect platelet specific antibodies in 35 patients with hematological disease. Subsequently, the Capture-P method was employed to perform 102 crossmatchings between plasma with HLA-Ⅰ antibodies and platelets with known HLA-Ⅰ genotypes. The cross-matching results were assessed and the clinical transfusion outcomes were tracked. [Results] The positive detection rate of HLA-Ⅰ and HPA antibodies in this study was 48.6% (17/35). The negative rate of cross-matching in 102 cases was 37.3% (38/102). Multiple factors affect platelet cross-matching, such as HLA-Ⅰ antibody expression level and antibody type, antigen expression level, cross-reactivity group and eplets. Among them, the expression level and antibody type of HLA-Ⅰ antibody are the main influencing factors. However, the effectiveness of clinical platelet transfusion is not completely determined by the compatibility of platelet cross-matching. [Conclusion] In addition to avoiding strong positive HLA-Ⅰ antibodies, clinical matching should also be vigilant against the serological cross-incompatibility caused by weak positive HLA-Ⅰ antibodies. It may be necessary to establish HLA-Ⅰ low expression antigen database as a better alternative platelet donor selection strategy, and gradually explore the effectiveness of ‘low expression mismatch’ strategy for clinical platelet transfusion.

Tumorigenesis, invasion, and metastasis occur in the context of a persistent inflammatory microenvironment, and a variety of inflammatory factors can lead to the development of various tumors. Guided by the thought of "preventive treatment of disease" in TCM and the concept of tertiary prevention in modern medicine, it is of great significance to effectively intervene in the inflammatory stage of the disease, interrupt disease progression, prevent the occurrence of malignant tumors, and reverse the process of "inflammation-to-cancer transformation". Sinisan, a commonly used prescription in the Treatise on Febrile Diseases, has been widely applied in the treatment of precancerous lesions of the digestive system, demonstrating considerable advantages. This article reviewed literature from the past 20 years, summarizing the application of Sinisan in precancerous lesions of the digestive system from three aspects: the exploration of its prescription-syndrome relationship, clinical application, and mechanistic study. It is found that basic syndrome indications of Sinisan include harmonizing the Earth element to promote spleen-stomach transportation and transformation, soothing the liver and nourishing the Wood element to restore the smooth flow of Qi, and regulating Yin and Yang to relieve stagnation within the system. In clinical application, Sinisan has shown significant efficacy in atrophic gastritis and precancerous conditions such as intestinal metaplasia, gastric ulcer, ulcerative colitis, esophagitis, and pancreatitis. Mechanistic studies have revealed that Sinisan can inhibit inflammatory factors and improve the inflammatory microenvironment, inhibit cell proliferation and regulate apoptosis, exhibit anti-angiogenic and antitumorigenic effects, modulate immune function, and exert antioxidant effects. These mechanisms can be achieved by regulating pathways such as nuclear factor erythroid 2-related factor 2/heme oxygenase-1 (Nrf2/HO-1), farnesoid X receptor (FXR)/Nrf2, phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt), Takeda G protein-coupled receptor 5/cyclic adenosine monophosphate/protein kinase A (TGR5/cAMP/PKA), interleukin-4/signal transducer and activator of transcription 6 (IL-4/STAT6), Janus kinase/signal transducer and activator of transcription (JAK/STAT), RhoA/Rho-associated protein kinase (RhoA/ROCK), and transforming growth factor-β/Smad proteins (TGF-β/Smads), confirming Sinisan's role in reversing the inflammation-to-cancer transformation. The current research status of Sinisan in precancerous lesions of the digestive system was thoroughly examined through the above three aspects, along with the identification of limitations and areas for improvement in current research. The aim is to provide a basis and support for future in-depth research on Sinisan, promote the development of new integrated treatment models combining TCM and Western medicine for precancerous lesions, and aid in the research and development of drugs related to precancerous lesions.

Malignant tumor is a serious and difficult disease threatening human health, which has a high morbidity and mortality rate worldwide. Traditional Chinese medicine has unique advantages in improving the therapeutic effect of malignant tumors and alleviating adverse reactions. Traditional Chinese medicine believes that Qi deficiency and blood stasis are important pathogeneses in the development of malignant tumors, and the method of supplementing Qi and activating blood is an effective strategy for treating malignant tumors. Astragali Radix, sweet in taste and warm in nature, has effects of tonifying Qi and rising Yang, strengthening the exterior and reducing sweat, promoting fluid and nourishing blood. Curcumae Rhizoma, acrid and bitter in taste and warm in nature, has the effects of promoting Qi and breaking blood stasis, eliminating mass, and relieving pain. Astragali Radix-Curcumae Rhizoma, as the classic herb pair of invigorating Qi and activating blood, has a clear effect on inhibiting tumor growth and metastasis. Studies have shown that Astragali Radix-Curcumae Rhizoma contains astragalus polysaccharide, astragaloside, calycosin, formononetin, curcumin, β-elemene, curcumenol, curcumenone, curcumendione, gemacrone, and other anti-tumor active ingredients. It can significantly inhibit the occurrence and development of liver cancer, colorectal cancer, gastric cancer, lung cancer, ovarian cancer, cervical cancer, breast cancer, and other cancers and has the advantages of superposition effect, synergistic complementarity, and increased dissolution compared with single herb and monomer of Chinese traditional herbs and has been widely valued in the field of TCM anti-cancer. Its anti-tumor mechanism includes inhibition of tumor cell proliferation, promotion of tumor cell apoptosis and autophagy, anti-invasion and metastasis, regulation of immune function, and enhancement of anti-tumor drug sensitivity. By combining Chinese and foreign literature, the compatibility effect and anti-tumor mechanism of Astragali Radix-Curcumae Rhizoma were summarized, and then scientific compatibility of these two herbs was expounded, in order to provide a useful reference for clinical application and future research of Astragali Radix-Curcumae Rhizoma.

Objective:To identify the development trajectories of self-neglect behavior in older adults and explore the associated influencing factors.Methods:A fixed cohort was constructed based on the data from three surveys of Chinese longitudinal healthy longevity survey (CLHLS) from 2011 to 2018. A total of eight variables from 4 dimensions including living environment, lifestyle, social interaction, and health care were selected to evaluate self-neglect. Group-based trajectory model was used to identify the development trajectory of self-neglect behavior in the older adults, and polynomial Logistic regression model was used to explore its influencing factors by Stata 16.1.Results:Finally, 2 754 older adults aged 60 and above were included.The development trajectory of self-neglect behavior in older adults, based on the group-based trajectory model, can be classified into stable-low group ( n=268, 9.7%), descending-moderate group ( n=2 224, 80.8%), and decreasing-high group ( n=262, 9.5%). Polynomial Logistic regression showed that, compared with stable-low group, living in rural areas ( B=1.116, OR=3.053, 95% CI= 2.278-4.091) and higher activities of daily living scores( B=0.137, OR=1.147, 95% CI=1.046-1.258) were the risk factors of descending-moderate group. Education levels with 1-6 years( B=-0.398, OR=0.672, 95% CI=0.469-0.963), >6 years( B=-1.072, OR=0.342, 95% CI=0.229-0.513), being married( B=-0.476, OR=0.621, 95% CI=0.444-0.870), self-reported good health( B=-0.808, OR=0.446, 95% CI= 0.213-0.932), improved health status( B=-0.704, OR=0.495, 95% CI=0.320-0.766), self-reported average economic status( B=-1.065, OR=0.345, 95% CI=0.148-0.802), self-reported good economic status( B=-1.634, OR=0.195, 95% CI=0.082-0.467), and a higher cognition score( B=-0.142, OR=0.867, 95% CI=0.798-0.942) served as protective factors of descending-moderate group. In addition to the above factors, being in the age group of 75-89 years( B=0.481, OR=1.617, 95% CI=1.057-2.473) was a risk factor for decreasing-high group compared to stable-low group. Conclusions:Three types of self-neglect behavior trajectories among older adults were identified in this study, suggesting that physical health and economy are the influencing factors of the development trajectory of self-neglect of the elderly.

The protein kinase B(Akt)pathway can regulate the growth,proliferation,and metabolism of tumor cells and stem cells through the activation of multiple downstream target genes,thus affecting the development and treatment of a range of diseases.Thioesterase superfamily member 4(THEM4),a member of the thioesterase superfamily,is one of the Akt kinase-binding proteins.Some studies on the mechanism of cancers and other diseases have shown that THEM4 binds to Akt to regulate its phosphorylation.Initially,THEM4 was considered an endogenous inhibitor of Akt,which can inhibit the phosphorylation of Akt in diseases such as lung cancer,pancreatic cancer,and liver cancer,but subsequently,THEM4 was shown to promote the proliferation of tumor cells by positively regulating Akt activity in breast cancer and nasopharyngeal carcinoma,which contradicts previous findings.Considering these two distinct views,this review summarizes the important roles of THEM4 in the Akt pathway,focusing on THEM4 as an Akt-binding protein and its regulatory relationship with Akt phosphorylation in various diseases,especially cancer.This work provides a better understanding of the roles of THEM4 combined with Akt in the treatment of diseases.

Objective:To explore the value of jellyfish sign, an abnormal ultrasonographic sign, in predicting adverse perinatal outcomes of women with complete placenta previa combined with placenta accreta spectrum disorders (PAS).Methods:This retrospective study analyzed the ultrasound images of 72 singleton gravidas, diagnosed with complete placenta previa combined with PAS, who underwent cesarean section at the First Affiliated Hospital of Nanjing Medical University between January 2020 and February 2023. Based on the presence and absence of the jellyfish sign in ultrasound images, these gravidas were divided into the jellyfish-sign group (15 cases, 20.8%) and the non-jellyfish-sign group (57 cases, 79.2%). The clinical data and perinatal outcomes of the two groups were analyzed. The adverse perinatal outcomes encompassed conditions such as abdominal aorta balloon block, uterine artery embolism, hysterectomy, postpartum hemorrhage, and neonatal intensive care unit (NICU) admission of their neonates. Statistical analysis was performed using two independent samples t-test, the Mann-Whitney U test and the Chi-square (or Fisher's exact) test. Results:(1) The jellyfish-sign group exhibited a higher parity [(1.6±0.7) times vs (1.2±0.6) times, t=2.01] and higher prenatal scores of placenta accreta [(12.3±1.5) scores vs (8.6±2.9) scores, t=6.59] than those in the non-jellyfish-sign group (both P<0.05). Among the 57 cases in the non-jellyfish-sign group, there were 14 cases of placenta creta (24.6%), 40 cases of placenta increta (70.2%), and three cases of placenta percreta (5.3%). Among the 15 cases in the jellyfish-sign group, nine cases were diagnosed with placenta increta, six with placenta percreta, and none with placenta creta. The difference in distribution between the two groups was statistically significant (Fisher's exact test, P<0.001). (2) Intraoperative blood loss [(for those who accepted abdominal aorta balloon block, 1 973±1 057) ml vs (1 211±576) ml, t=2.55], red blood cells transfused [4.0 U (2.0-23.0 U) vs 2.5 U (0.0-11.0 U), Z=-2.53], postoperative hospitalization time [(9.7±2.4) vs (7.5±2.2) d, t=3.36], the incidence of abdominal aorta balloon block [15/15 vs 38.6% (22/57), χ2=17.92], uterine artery embolism [for those who accepted abdominal aorta balloon block, 3/15 vs 1.8% (1/57), Fisher's exact test], and requiring blood transfusion [15/15 vs 63.2% (36/57), Fisher's exact test] were higher in the jellyfish-sign group than those in the non-jellyfish-sign group. However, the non-jellyfish-sign group had lower gestational age at delivery [(33.6±1.5) weeks vs (35.2±1.8) weeks, t=-3.24], and lower neonatal Apgar score at 1 min and 5 min [1 min: 8 scores (3-10 scores) vs 9 scores (4-10 scores), Z=-2.46; 5 min: 9 scores (7-10 scores) vs 10 scores (6-10 scores), Z=-2.02] (all P<0.05). There were no significant differences in emergency surgery rate, 24 h postoperative blood loss, neonatal birth weight, and proportion of NICU admission between the two groups. Additionally, no cases of hysterectomy or death were observed in the two groups. Conclusions:Ultrasound examination revealing jellyfish signs in patients with complete placenta previa and PAS is associated with an increased likelihood of adverse perinatal outcomes. Consequently, the management of these patients should be given greater attention.
