OBJECTIVE: This review summarized the first 10-year progresses and controversies in the concept of anteromedial cortical support reduction, to provide references for further study and clinical applications. METHODS: Relevant domestic and foreign literature on cortical support reduction was extensively reviewed to summarize the definition of positive, neutral, and negative support, anteromedial cortices at the inferior corner, intraoperative technical tips for fracture reduction, radiographic assessment at different periods, comparison between positive versus neutral and medial versus anterior support, and the clinical efficacy of Chang reduction quality criteria (CRQC) and postoperative stability score. RESULTS: Anteromedial cortical support reduction was only focused on the cortex of anteromedial inferior corner, with no concern the status of lateral wall or lesser trochanter. Anteromedial cortex was seldom involved by fracture comminution, it was thicker, denser, and stronger, and was the key for mechanical buttress of the head-neck fragment to share compression load. Positive, neutral, and negative support were also called "extramedullary, anatomic, and intramedullary reduction", respectively. There was hardly seen parallel cortical apposition, but characterized by some kinds of head-neck rotation, for example 10°-15° flexed rotation for positive cortical contact and support. Due to intraoperative compression and postoperative impaction, the status of cortical support may be changed at different time of radiographic examination. The positive medial cortex support was more reliable with less reduction loss than its neutral counterpart, and the anterior cortex contact was more predictive than the medial cortex for final results. As incorporation the bearing of cortex apposition and using a 4-point score, CRQC demonstrated more efficacy and was gradually accepted and applied in the evaluation of trochanteric fracture reduction quality. Postoperative stability score (8 points) provided a assessment tool for early weight-bearing in safety to prevent mechanical failure. CONCLUSION Anteromedial cortical support reduction is a key point for stability reconstruction in the treatment of trochanteric femur fractures. Evidence has definitely shown that non-negative (positive and neutral) is superior to negative (loss of cortical support). There is a tendency that positive cortex support is superior to neutral, but high quality study with large sample size is needed for a clear conclusion.

Background and purpose:Gastric cancer,as one of the most common malignant tumors,requires early diagnosis and treatment to improve patient prognosis.This study,based on serum quantitative proteomics research of early-stage gastric cancer patients and non-gastric cancer patients,aims to identify potential diagnostic biomarkers for early gastric cancer.Methods:Serum samples from primary gastric cancer patients and healthy control individuals were collected from Lanzhou University Second Hospital between June and December 2023,following inclusion and exclusion criteria.A protein spectral library was established using Data-Dependent Acquisition(DDA)mode,and each sample was analyzed using Data-Independent Acquisition(DIA)mode.The STRING database was used to analyze protein-protein interactions of upregulated proteins in gastric cancer serum.Kyoto Encyclopedia of Genes and Genomes(KEGG)and Gene Ontology(GO)were used to analyze the pathways and functional annotations of the corresponding genes.Gene expression levels in gastric cancer and non-gastric cancer tissues were analyzed using GEPIA 2,and overall survival of each gene in gastric cancer was analyzed using Kaplan-Meier Plotter.Differential gene expression in clinical gastric cancer and adjacent tissues was validated by quantitative reverse transcription polymerase chain reaction(qRT-PCR)This study was approved by the Ethics Committee of Lanzhou University Second Hospital(Ethical No.:2023A-459)and was exempt from the informed consent.Results:Finally,serum samples from 30 primary gastric cancer patients,29 healthy control individuals,along with the para-cancerous tissues from 8 patients were collected.A total of 666 intersecting proteins were identified through serum quantitative proteomics.Among them,16 proteins showed upregulated expression and 22 proteins showed downregulated expression in the gastric cancer group(P＜0.05,|FC|≥1.5).STRING database analysis showed that 10 upregulated proteins were involved in interaction networks.KEGG and GO analysis indicated that these genes were closely related to the biological processes of cancer occurrence and development.GEPIA 2 and Kaplan-Meier Plotter analysis showed that 6 genes,B2M,TAGLN2,CTSD,HSP90AB1,SH3BGRL3,and CFL1,which were highly expressed in the gastric cancer group(P＜0.05)and associated with poor prognosis.Clinical verification by qRT-PCR confirmed that TAGLN2,CTSD,SH3BGRL3,CFL1 and HSP90AB1 were highly expressed in gastric cancer tissues(P＜0.05).Conclusion:TAGLN2,CTSD,SH3BGRL3,CFL1,and HSP90AB1 have the potential to serve as clinical early gastric cancer diagnostic serum biomarkers,which may facilitate early diagnosis and treatment of gastric cancer.

Diabetes is a chronic disease that requires lifelong medication and long-term management. The longer the duration of the disease, the more likely it is to lead to progressive chronic complications affecting the eyes, kidneys, nervous system, and cardiovascular system. These complications may result in gradual functional decline or even organ failure, and may also trigger severe acute metabolic disorders. The cumulative financial burden on patients and their families can be substantial, giving rise to what is known as financial toxicity, which in turn may negatively affect patients' health outcomes. This review comprehensively explores the concept of financial toxicity in diabetic patients, including its assessment tools, influencing factors, and coping strategies. It also offers targeted suggestions aimed at informing the development of more scientific and effective systemic interventions, with the ultimate goal of improving treatment outcomes and quality of life for individuals living with diabetes.

Objective To investigate the influence of intravenous esketamine infusion on anesthetic effect and awakening quality in elderly patients undergoing laparoscopic surgery for prostate cancer.Methods One hundred and twenty patients with laparoscopic radical prostatectomy were selected and divided into the esketamine group(group E)and control group(group C)by the random number table method,60 ca-ses in each group.The group E used esketamine for anesthesia induction and maintenance,while the group C received the same amount of physiological saline at the same time during operation process as control.The es-ketamine pumping infusion or normal saline in the two groups was stopped at 30 min before operation end.In addition,the types and doses of other drugs used during the induction and maintenance phase of anesthesia were identical between the two groups.The use total amounts of anesthetic drugs during perioperative period were recorded.The heart rate(HR)and mean arterial pressure(MAP)were recorded before operation(T1),instantly before tracheal intubation(T2),at 1 min after tracheal intubation(T3),1 h during surgery(T4),end of skin suture(T5),and 5 min after extubation(T6)in the two groups respectively;the anesthetic recovery time after extubation was recorded.The Riker sedation and restlessness score was used to conduct the agita-tion evaluation,the incidence rates of agitation and bucking and the resuscitation room stay time were recor-ded.The pain VAS score was used to conduct the pain evaluation in the patients.The incidence rates of ad-verse events such as respiratory depression,shiverring,nausea,vomiting,drowsiness after extubation were re-corded.Results The perioperative doses of resutanil and propofol in the group E were significantly lower than those in the group C,and the difference was statistically significant(P＜0.05).HR and MAP at T2 in the group E were higher than those in the group C,while HR and MAP at T3 in the group E were lower than those in the group C.The recovery time after extubation in the group E was longer than that in the group C,the agitation incidence rate,acute bucking incidence rate and VAS score were lower,the stay time in the recov-ery room was shorter.The incidence rate of drowsiness in the group E was significantly higher than that in the group C(P＜0.05).The incidence rates of other adverse events had no statistical differnece(P＞0.05).Con-clusion Esketamine is safe and effective in the elderly patients with laparoscopic prostate cancer surgery,which is conducive to stabilize the hemodynamic parameters and reduce the incidence rate of agitation and buc-king.

Urolithiasis represents a prevalent clinical challenge marked by high recurrence rates and morbidity，with existing preventive strategies struggling to effectively curb its epidemic trajectory，thereby posing a significant threat to public health. The etiology of this condition is intricate，involving a complex network of interactions spanning classical supersaturation-crystallization theory，Randall’s plaque theory，and multifactorial elements such as cellular injury，inflammatory responses，metabolic derangements，the gut-kidney axis，immune dysregulation，and genetic predisposition. However，the critical mechanisms initiating stone formation and the early pathophysiological processes remain incompletely elucidated，constituting the core impasse in current preventive strategies. This review systematically synthesizes classical theories and cutting-edge advancements in urolithiasis etiology research，emphasizing the urgent need to integrate emerging technologies，including high-dimensional omics，advanced imaging modalities，and artificial intelligence，to dissect pivotal pathological nodes in early stone formation. Such interdisciplinary efforts are essential to overcome cognitive bottlenecks and ultimately achieve personalized，precision-based prevention strategies.

Epigenomic imbalance drives abnormal transcriptional processes,promoting the onset and progression of cancer.Although defective gene regulation generally affects carcinogenesis and tumor suppression networks,tumor immunogenicity and immune cells involved in antitumor responses may also be affected by epigenomic changes,which may have significant implications for the development and application of epigenetic therapy,cancer immunotherapy,and their combinations.Herein,we focus on the impact of epigenetic regulation on tumor immune cell function and the role of key abnormal epigenetic processes,DNA methylation,histone post-translational modification,and chromatin structure in tumor immunogenicity,and introduce these epigenetic research methods.We emphasize the value of small-molecule inhibitors of epigenetic modulators in enhancing antitumor immune responses and discuss the challenges of developing treatment plans that combine epigenetic therapy and immuno-therapy through the complex interaction between cancer epigenetics and cancer immunology.

Objective To observe the effect of pre-hospital and intra-hospital collaborative ther-apeutic model in the treatment of patients with acute cerebral infarction.Methods A total of 67 pa-tients with acute cerebral infarction were selected as the research objects,and they were divided into observation group(n=37)and control group(n=30)according to the therapeutic model.The con-trol group was conducted with the traditional therapeutic model,while the observation group was con-ducted with the pre-hospital and intra-hospital collaborative therapeutic model.The time efficiency of intravenous thrombolysis,early recovery of nerve function and oxidative stress indexes were compared between the two groups.Results There was no significant difference in the time from onset to visit between the two groups(P＞0.05);the time from seeing a doctor to thrombolysis and the time from seeing a doctor to signing the informed consent for intravenous thrombolysis in the observation group were significantly shorter than those in the control group(P＜0.05).On the hospital admission,there was no significant difference in the National Institutes of Health Stroke Scale(NIHSS)score be-tween the two groups(P＞0.05);at the time points of 7 days after admission and 90 days after thrombolysis,the NIHSS scores of patients in the observation group were significantly lower than that in the control group(P＜0.05).There were no significant differences in the levels of serum glutathione peroxidase(GSH-Px)and malonaldehyde(MDA)between the two groups(P＞0.05);the level of serum superoxide dismutase(SOD)in the observation group was significantly higher than that in the control group(P＜0.05).One patient died in the control group,with a mortality rate of 3.33％;no patient died in the observation group.Conclusion Pre-hospital and intra-hospital collaborative therapeutic model can effectively improve the time efficiency of intravenous thrombolysis for patients with acute cerebral infarction,alleviate the neurological damage,and reduce degree of oxidative stress reaction and death risk.
