BACKGROUND: Huaier granule is an important medicinal fungus extract widely used in cancer treatment. Previous retrospective studies have reported its effectiveness in breast cancer patients, but the imbalanced baseline characteristics of participants could have biased the results. Therefore, this retrospective study aimed to examine the efficacy of Huaier granule on the prognosis of breast cancer patients. METHODS: In this single-center cohort study, breast cancer patients diagnosed and treated at the Guangdong Provincial Hospital of Chinese Medicine between 2009 and 2017 were selected. The data were retrospectively analyzed and divided into two groups according to whether the patients received Huaier granules. The propensity score matching (PSM) method was used to eliminate selection bias. The disease-free survival (DFS) and overall survival (OS) for these groups were compared using the Kaplan-Meier method and the Cox regression. RESULTS: This study included 214 early invasive breast cancer patients, 107 in the Huaier group and 107 in the control group. In the Kaplan-Meier analysis, the 2-year and 5-year DFS rates were significantly different in the Huaier group and control group (hazard ratio [HR], 0.495; 95% confidence interval [CI], 0.257-0.953; P = 0.023). The 2-year and 5-year OS rates were also significantly different (HR, 0.308; 95% CI, 0.148-0.644; P = 0.001). On multivariable Cox regression, Huaier granule was associated with improved DFS (HR, 0.440; 95% CI, 0.223-0.868; P = 0.018) and OS (HR, 0.236; 95% CI, 0.103-0.540; P = 0.001). CONCLUSION In this retrospective study, Huaier granules improved the DFS and OS of early invasive breast cancer patients, providing real-world evidence for further prospective studies on treating breast cancer with Huaier granules.

Malignant tumors(commonly referred to as cancers)represent a major global public health challenge and contribute substan-tially to the global disease burden.Early screening plays a crucial role in improving detection rates,enabling timely intervention,and enhan-cing patient survival.However,current cancer screening guidelines primarily focus on site-specific screening,which may not fully address the need for comprehensive early detection.A scientifically rational,multi-cancer screening approach offers several advantages:it optimizes the use of biological samples,reduces the time burden for participants,enhances the efficiency and comprehensiveness of screening,and min-imizes overall expenses.Moreover,this approach facilitates rational allocation of healthcare resources,ultimately helping to reduce the soci-etal burden of cancer.To address gap,the Cancer Epidemiology Committee of the China Anti-Cancer Association has developed the Expert Consensus on Combined Screening for Common Cancers.This consensus integrates multidisciplinary expertise and synthesizes the latest do-mestic and international researches on cancer screening,early detection,and treatment of prevalent malignancies.Drawing upon China's unique demographic and healthcare context and practical screening experiences,the consensus provides evidence-based recommendations on target populations,screening technologies,and procedural workflows for multi-cancer screening.These guidelines align with the prin-ciples and methodologies established by the World Health Organization(WHO),aiming to enhance the effectiveness of combined cancer screening in China,improve early detection rates,and provide a scientific foundation for national cancer prevention and control strategies.

BACKGROUND:Magnetic resonance imaging is the gold standard for the diagnosis of osteonecrosis of femoral head,and previous methods of predicting osteonecrosis of femoral head collapse based on magnetic resonance images mostly require the combined assessment of coronal and sagittal images.However,osteonecrosis of femoral head tends to occur bilaterally,most hospitals perform bilateral hip magnetic resonance imaging scans during clinical examinations,but the bilateral hip scans can only view coronal and cross-sectional images,and it is difficult to obtain sagittal images,which affects the assessment of the risk of collapse.Therefore,it is of clinical value to establish a method to assess the risk of early osteonecrosis of femoral head collapse by applying the images that can be obtained after bilateral hip magnetic resonance scanning. OBJECTIVE:To establish a method of applying coronal and cross-sectional images of bilateral hip magnetic resonance imaging to assess the risk of osteonecrosis of femoral head collapse. METHODS:The medical records of 111 patients(181 hips)with early-stage osteonecrosis of femoral head diagnosed at the outpatient clinic of Honghui Hospital Affiliated to Xi'an Jiaotong University from October 2017 to October 2019 were retrospectively analyzed.They were categorized into collapsed and non-collapsed groups according to the femoral head collapse at the final follow-up,with 69 hips in the collapsed group and 112 hips in the non-collapsed group.The angle of necrotic range on the images of median coronal plane,transverse plane or one level above and below it was measured on the magnetic resonance imaging system.The sum of the two angles of necrotic angle on the coronal and transverse planes was used as the combined necrotic angle.The average of the three combined necrotic angles of each hip was taken to get the average combined necrotic angle of each hip.Finally,the correlation between the three combined necrotic angles and the average combined necrotic angle with the collapse of osteonecrosis of femoral head was analyzed,and the specificity and sensitivity of the four combined necrotic angles in predicting collapse were evaluated by using receiver operating characteristic curves. RESULTS AND CONCLUSION:(1)Totally 69 hips(38.1%)had femoral head collapse at the last follow-up and were included in the collapsed group;112 hips(61.9%)did not have progression of collapse and were included in the non-collapsed group.(2)The difference between the collapsed group and the non-collapsed group in terms of Association Research Circulation Osseous(ARCO)stage was significant(P<0.001).The difference in age,body mass index,follow-up time,gender distribution,side of onset,and causative factors was not significant(P>0.05).(3)The results of independent samples t-test suggested that all four combined necrotic angles were significantly correlated with collapse(P<0.000 1);and the differences in combined necrotic angles between the collapsed group and the non-collapsed group of ARCO stage I and the two groups of ARCO stage II were all significant(P<0.000 1).(4)In the analysis of the receiver operating characteristic,the area under the curve of the average combined necrotic angle was greater than that of the combined necrotic angle on the lower level of the median,the middle level,and the upper level of the median.(5)The average combined necrotic angle had a higher accuracy in the prediction of collapse than the lower level of the median,the middle level,and the upper level of the combined necrotic angle.(6)It is concluded that the accuracy of the average combined necrotic angle in predicting the risk of osteonecrosis of femoral head collapse is higher,and the clinical practicability is stronger,so we can consider using this method to predict the risk of osteonecrosis of femoral head collapse.

Objective To investigate the role and molecular mechanism of SOX4 in Helicobacter pylori(H.pylori)-mediated gastric mucosal epithelial dysplasia.Methods The expression of SOX4 in gastric tissues and cells was analyzed with reverse transcription-polymerase chain reaction(RT-PCR),Western blotting,and immunohistochemical staining.The effects of SOX4 on gastric epithelial cell proliferation and colony formation were determined with CCK-8 and colony formation assays.A PCR array was used to screen downstream target genes involved in H.pylori-induced dysplasia mediated by SOX4.The transcriptional regulation and binding sites of the target gene MLH3 by SOX4 were elucidated with luciferase reporter assay,promoter truncation assay,and chromatin immunoprecipitation(ChIP).Results SOX4 expression was significantly increased in H.pylori-infected gastric tissues(P<0.05).Overexpression of SOX4 markedly enhanced the proliferation and colony formation abilities of normal gastric epithelial cells(P<0.05).Elevated SOX4 led to the dysregulation of MLH3 and other DNA damage repair-related molecules after H.pylori infection in gastric epithelial cells(|logFC|>1,P<0.05).H.pylori promoted MLH3 expression in gastric epithelial cells through SOX4.SOX4 transcriptionally activated MLH3 expression by binding to the 5th site of the MLH3 promoter.The increased expression of SOX4 and MLH3 is associated with poor prognosis of gastric cancer patients.Conclusion SOX4 is closely associated with H.pylori-induced dysplasia in gastric epithelial cells.Upregulation of SOX4 promotes H.pylori-related dysplasia by transcriptionally activating MLH3,leading to the imbalance of proliferation and colony formation in gastric epithelial cells.

With the rapid advancement and iterative development of new artificial intelligence technologies, there remains a regulatory vacuum in corresponding governance measures among governments worldwide. Simultaneously, a technological and governance gap exists between developing countries and developed economies. In response, the World Health Organization (WHO) has released "Ethics and Governance of Artificial Intelligence for Health: Guidance on Large Multi-Modal Models" to assist governments in strengthening governance capabilities in this field. This paper provides an in-depth analysis of the Guidance, aiming to identify challenges and risks associated with the application of multimodal large models in healthcare. Guided by ethical principles for advancing health through artificial intelligence, the paper examines the three-tier governance framework and recommendations outlined in the Guidance. Additionally, it evaluates the current state of AI governance in China, offering insights and reference points for improving AI governance in China′s healthcare sector.

Stresses induced by the deficiency or excess of trace mineral elements, such as manganese (Mn), represent a common limiting factor for the production of crops like Brassica napus. To identify key genes involved in Mn allocation in B. napus and elucidate the underlying mechanisms, a member of the metal tolerance protein (MTP) family obtained in the previous screening of cDNA library of B. napus under Mn stress was selected as the research subject. Based on the sequence information and phylogenetic analysis, it was named as BnMTP10. It belongs to the Mn-cation diffusion facilitator (CDF) subfamily. Expression of BnMTP10 in yeast significantly improved the tolerance of transformants to excessive Mn and iron (Fe) and reduced the accumulation of Mn and Fe. However, the yeast transformants exhibited no significant changes in tolerance to excess cadmium, boron, aluminum, zinc, or copper. The qRT-PCR results demonstrated that the flowers of B. napus had the highest expression of BnMTP10, followed by roots and leaves. Subcellular localization studies revealed that BnMTP10 was localized in the endoplasmic reticulum (ER). Compared with wild-type plants, transgenic Arabidopsis overexpressing BnMTP10 exhibited enhanced tolerance to excessive Mn stress but showed no significant difference under Fe stress. Correspondingly, under excessive Mn stress, the Mn content in the roots of transgenic Arabidopsis increased significantly. However, under excessive Fe stress, the Fe content in transgenic Arabidopsis did not alter significantly. According to the results, we hypothesize that BnMTP10 may alleviate excessive Mn stress in plants by mediating Mn transport to the ER. This study facilitated our understanding of efficient mineral nutrients, and provided theoretical foundations and gene resources for breeding B. napus.

BACKGROUND:Postoperative fever is one of the common clinical symptoms after posterior lumbar interbody fusion. There is no clear etiology or pathogenesis. The postoperative body temperature of patients is easy to repeat,the course of the disease is long,and the therapeutic effect of western medicine is poor,which affects the postoperative recovery of patients. OBJECTIVE:To review the relationship between inflammatory signaling pathways and postoperative fever and the mechanism of Chinese medicine inpreventing and treating fever after posterior lumbar interbody fusion,and to explore new therapeutic drugs for postoperative fever.METHODS:The CNKI Chinese Journal full-text database,WanFang database,and PubMed database were searched for articles published from June 2006 to December 2023. Chinese search terms were "Chinese medicine,postoperative fever,inflammation,interleukin-1,interleukin-6,interleukin-8,interferon gamma,tumor necrosis factor,prostaglandin E2,p38 mitogen-activated protein kinase,nuclear factor-κB,Toll-like receptor,Janus kinases/signal transduction and transcriptional activator,Notch signaling pathway." English search terms were "medicinal herb,postoperative fever,inflammation,interleukin-1,interleukin-6,interleukin-8,γ-interferon,tumor necrosis factor,prostaglandin E2,p38 mitogen-activated protein kinase,nuclear factor-κB,toll-like receptor,janus kinases/signal transducer and activator of transcription,notch signaling pathway." Articles with irrelevant research content and poor quality were excluded,and 100 articles were included and summarized.RESULTS AND CONCLUSION:(1) The operation induced the release of inflammatory factors,and the pro-inflammatory factors acted on the thermoregulatory center in the anterior hypothalamus to promote fever. (2) The absorption of bleeding and oozing fluid in the incision after surgery,and the phagocytosis of the egg white decomposition products of the necrotic cells,produce endogenous pyrogen (interleukin,tumor necrosis factor,interferon,etc.),leading to fever. (3) Cytokines pass through inflammatory signals,play an inflammatory role,and promote fever. (4) Chinese herbs or Chinese herbal compounds can regulate inflammatory signaling pathways and play an anti-inflammatory and antipyretic role in preventing and treating postoperative fever. Due to the lack of the mechanism of action of traditional Chinese medicine,it is necessary to further study and clarify the signaling pathways related to the prevention and treatment of postoperative fever by traditional Chinese medicine,and use modern technology to link cellular and molecular technology with the pharmacological mechanism of traditional Chinese medicine,so as to guide clinicians to use medicine and promote postoperative recovery of patients. (5) Chinese medicine combined with Western medicine in the treatment of postoperative fever is a future research hotspot. We should give full play to the advantages of Chinese medicine,and clarify the target mechanism of action of different syndrome types of Chinese medicine monomer or active ingredient extracts and Chinese medicine decoction.
