Depression is increasingly prevalent among adolescents and can profoundly impact their lives. However, the early detection of depression is often hindered by the time-consuming diagnostic process and the absence of objective biomarkers. In this study, we propose a novel approach for depression detection based on an affective brain-computer interface (aBCI) and the resting-state electroencephalogram (EEG). By fusing EEG features associated with both emotional and resting states, our method captures comprehensive depression-related information. The final depression detection model, derived through decision fusion with multiple independent models, further enhances detection efficacy. Our experiments involved 40 adolescents with depression and 40 matched controls. The proposed model achieved an accuracy of 86.54% on cross-validation and 88.20% on the independent test set, demonstrating the efficiency of multimodal fusion. In addition, further analysis revealed distinct brain activity patterns between the two groups across different modalities. These findings hold promise for new directions in depression detection and intervention.

Objective To investigate the effects of miR-1 on the proliferation,migration and invasion of esophageal squamous cell carcinoma.Methods miR-1 mimics,inhibitors and their corresponding controls were transfected into ESCC cells ECa109 and KYSE410.The efficiency of cell transfection was validated by SYBR-green quantitative PCR.The proliferation,migration and invasion ability of ESCC cells were assessed by MTT,foci formation,wound healing and Matrigel invasion assays,respectively.Statistical analysis was carried out using SPSS 22.0software for Windows.Results Overexpression of miR-1 markedly inhibited the cell growth rate and the colony-forming ability of the ESCC cells.While,downregulation of miR-1 promoted the cell growth rate and foci formation(P＜0.05).And upregulation or downregulation of miR-1 significantly suppressed or promoted tumor cell invasion and migration(P＜0.05).Conclu-sion miR-1 inhibited ESCC cell proliferation,invasion and migration,suggesting that miR-1 functions as a tumor suppressor in the tumorigenesis and progression of ESCC and may be a potential therapeutic target.

This paper summarizes the current status of research on the prevention and treatment of malignant tumors with traditional Chinese medicine(TCM),and points out that TCM has the advantages of being based on the holistic view and advocating the preven-tive treatment of diseases.The strategies of TCM in preventing and treating malignant tumors are proposed:first,it is necessary to clar-ify the leading or auxiliary treatment role in different stages of tumors and give full play to its strengths and advantages;second,find the characteristics of the superior and inferior populations and microscopic markers of tumor diagnosis and treatment to promote accurate di-agnosis and treatment;third,improve the overall diagnosis and treatment level of tumors by grasping the core pathogenesis and ensure clinical efficacy;fourth,incorporate modern medical therapy factors into the TCM tumor diagnosis and treatment system in order to in-tercept the disease;fifth,add TCM psychological intervention on the basis of the four-in-one holistic syndrome differentiation view to achieve harmony between body and spirit;sixth,improve the rehabilitation and health care system of tumors combined with traditional Chinese and Western medicine through the use of multiple methods to promote the recovery of diseases.In this way,the clinical effica-cy of TCM in preventing and treating tumors can be continuously improved,and the great goal of TCM in preventing and treating tumors and benefiting all mankind can be truly realized.

OBJECTIVE To investigate the inhibitory effect mechanism of Anzheng Kangliu Decoction against colorectal cancer by suppressing glycolysis through regulation of the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR)signaling pathway.METHODS Human colorectal cancer SW620 cells were treated with Anzheng Kangliu De-coction,and cell proliferation and migration abilities were assessed.Forty-two BALB/c nude mice were randomly divided into a blank control group,model group,5-fluorouracil(5-FU)group(0.025 g·kg-1),Anzheng Kangliu Decoction low-dose group(7.67 g·kg-1),medium-dose group(15.34 g·kg-1),and high-dose group(30.68 g·kg-1).The inhibitory effect of Anzheng Kan-gliu Decoction on subcutaneous xenograft tumors was evaluated by observing body weight,tumor volume,tumor mass,HE staining,im-munohistochemical staining of Ki67 and other indicators.High-throughput transcriptome sequencing was performed to identify differen-tially expressed genes and pathways in tumor tissues between the model group and the Anzheng Kangliu Decoction medium-dose group,elucidating the potential mechanism of Anzheng Kangliu Decoction against colorectal cancer.Glucose and lactate assay kits were used to measure glucose consumption and lactate production in SW620 cells and tumor tissues after Anzheng Kangliu Decoction intervention.Western blot was employed to detect the expression levels of p-PI3K/PI3K,p-Akt/Akt,p-mTOR/mTOR,hexokinase 2(HK2),and lactate dehydrogenase A(LDHA)in SW620 cells and tumor tissues following Anzheng Kangliu Decoction treatment.RE-SULTS In vitro cell experiments demonstrated that,compared with the blank control group,Anzheng Kangliu Decoction intervention significantly inhibited the proliferation and migration of SW620 cells(P<0.01),reduced glucose consumption and lactate production(P<0.05,P<0.01),and downregulated the protein expression levels of p-PI3K/PI3K,p-Akt/Akt,p-mTOR/mTOR,HK2,and LDHA(P<0.05,P<0.01).In vivo animal experiments revealed that,compared with the model group,Anzheng Kangliu Decoction suppressed the growth of subcutaneous xenograft tumors in nude mice(P<0.01),increased tumor tissue necrosis,decreased glucose consumption and lactate production in tumor tissues(P<0.05,P<0.01),and reduced the protein expression levels of p-PI3K/PI3K,p-Akt/Akt,p-mTOR/mTOR,HK2,and LDHA(P<0.05,P<0.01).CONCLUSION Anzheng Kangliu Decoction exerts an in-hibitory effect on colorectal cancer,and its mechanism may be associated with the suppression of glycolysis through regulation of the PI3K/Akt/mTOR signaling pathway.

Objective:To explore the sensitivity of intensity-modulated radiotherapy(IMRT)designed respectively by overlapping method and gradient optimization method on fixed field of whole brain and whole spinal cord of pediatric patients to positioning error.Methods:A retrospective study analyzed 10 pediatric patients who underwent radiotherapy on whole brain and whole spinal cord at The First Affiliated Hospital of Guangzhou Medical University during December 1,2022 and January 1,2024.Overlapping method and gradient optimization method were respectively adopted to design IMRT plan for whole brain and whole spinal cord.The length of the merged region of the field was set as 10 cm.The positioning errors of±1 mm,±3 mm and±5 mm on head-foot direction that occurred in spinal cord segmentation and other isocenter field were simulated,and the flux optimization did not be conducted,and the dose distribution was recalculated.The exposure doses of D2%,D98%,V30Gy,homogeneity index(HI),conformity index(CI)and organ at risk(OAR)of target regions in the merged region of field were recorded and compared,thus the robustness of the two optimization methods were assessed.Results:The IMRT plan of whole brain and whole spinal cord that were designed respectively by overlapping method and gradient optimization method can meet the clinical requirements under the condition that did not introduced positioning error.With the increasing of positioning error,the changes of cold and hot spots(ΔD2%,ΔD98%and ΔV30 Gy)of doses in the merged region of field were more and more significant.In the merged region of field,theΔD2%,ΔD98%and ΔV30 Gy of the overlapping method were respectively 13.98%±3.29%,-17.26%±3.44%and-44.06%±9.17%,and those of the gradient optimization method were respectively 6.0%±0.75%,-6.31%±0.81%and-37.37%±4.3%when positioning error was 5 mm.The differences of them between the overlapping method and the gradient optimization method were statistically significant(t=-10.889,15.928,2.808,P<0.05).Conclusion:With increase of positioning error in the merged region of field of IMRT plan for whole brain and whole spinal cord,the gradient optimization method can effectively relieve the changes of the cold and hot spots in the merged region of field,and its each indicator was less than that of the overlapping method.Therefore,it can effectively improve the plan's robustness.

Objective:To evaluate the repeatability of anterior segment biometry measurements obtained using ultrasound biomicroscopy (UBM) and the ArcScan Insight 100, and to compare the agreement between the two devices.Methods:A cross-sectional study was conducted.Seventy myopic patients (70 eyes) who underwent V4c implantable collamer lens implantation at Henan Eye Hospital from March to May 2023 were included.The ArcScan Insight 100 and UBM were used to measure the following parameters three times: angle-to-angle distance (ATA), sulcus-to-sulcus distance (STS), anterior chamber depth (ACD), crystalline lens rise (CLR), anterior chamber width (ACW), ciliary body inner diameter (CBID), anterior chamber angle (ACA), trabecular-ciliary angle (TCA) and maximum ciliary body thickness (CBTmax). The repeatability of anterior segment biological measurements obtained using the two devices was assessed by intraclass correlation coefficient (ICC). The consistency between the two instruments was evaluated by Bland-Altman consistency test.This study complied with the Declaration of Helsinki and was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2021[13]). All patients understood the purpose and significance of this study and signed the informed consent form.Results:The repeatability of ATA, STS, ACD, CLR, ACW, CBID, ACA, TCA and CBTmax measured by UBM and ArcScan Insight 100 was good (all ICC>0.9). There was no significant difference in ACD, ACW, and ACA between the two instruments ( t=0.696, -1.025, -1.447; all P>0.05). ATA, STS, CLR and CBID measured by UBM were lower and TCA and CBTmax were higher than those measured by UBM ArcScan Insight 100, and the differences were statistically significant ( t=-8.586, -12.551, -4.481, -4.420, 4.535, 7.812; all P<0.05). The differences of ATA, STS, ACD, CLR, ACW, CBID and CBTmax between UBM and ArcScan Insight 100 were 0.38, 0.47, -0.01, 0.07, 0.3, 0.26 and -0.21 mm, respectively, with the 95% limits of agreement (LoA) of (-0.34, 1.10), (-0.15, 1.09), (-0.28, 0.26), (-0.20, 0.35), (-0.33, 0.93), (-0.71, 1.23) and (-0.64, 0.23)mm, respectively, which showed good coherence.The differences in ACA and TCA measurements were 2.26° and -7.81°, respectively, and the 95%LoA values were (-23.36°, 27.89°) and (-36.05°, 20.43°), respectively, with poor coherence.There was a strong positive correlation in ACD measurements measured by UBM and ArcScan Insight 100 ( r=0.827, P<0.05). There were moderate positive correlations in ATA, STS, CLR, ACW and CBID ( r=0.678, 0.749, 0.617, 0.765, 0.519; all P<0.05). There was no significant correlation in ACA, TCA and CBTmax ( r=0.270, 0.032, 0.178; all P>0.05). Conclusions:The repeatability of ArcScan Insight 100 and UBM in measuring anterior segment biological parameters is good.However, the consistency of ACA, TCA and CBTmax measured by the two instruments is poor and may be affected by self-regulation of the body.ATA, STS, ACD, CLR, ACW and CBID have good consistency and can be used interchangeably.

Based on the theory of circulation of qi,a theoretical model of the circulation of phase fire in the human body was con-structed.It is proposed that cancer toxicity is the key factor that triggers the disorder of phase fire and hinders the circulation of phase fire.The disorder of phase fire and poor circulation are important pathogenesis of the occurrence and development of cancer toxicity.With the principle of strengthening healthy qi and eliminating evil qi,the Wenzi Jiedu method is used to treat tumors,which plays an important role in warming and nourishing,regulating yin and yang,and eliminating cancer toxicity.The combination of war-ming,nourishing and detoxification can promote the return of the phase fire and make the human body's generation and transformation active,providing a new treatment idea for TCM diagnosis and treatment of tumors with mainly cold poison or mixed cold and heat.
