Objective:To investigate the mechanism of LncRNA XIST on proliferation,apoptosis and invasion of tongue squamous cell carcinoma(TSCC)cells by regulating miR-337/ADAM28.Methods:qRT-PCR was used to detect the expression of XIST,miR-337,ADAM28 mRNA in TSCC tissues and cells.The expression of ADAM28,CyclinD1,MMP-9,MMP-14,Caspase-3 and Bax proteins was detected by Western blot.MTT assay was applied to detect cell activity.Transwell method was applied to detect the invasion ability of cells.Cell apoptosis was detected by flow cytometry.The double luciferase reporter gene experiment was applied to verify the targeting relationship between miR-337 and LncRNA XIST,miR-337 and ADAM28.Results:Compared with the adja-cent tissues,the expression of XIST and ADAM28 mRNA in TSCC increased,the expression of miR-337 decreased(P＜0.05).Compared with human normal oral mucosa cell HOK,the expression of XIST and ADAM28 in human TSCC cell lines increased,the expression of miR-337 decreased(P＜0.05).Silencing XIST reduced the expression of CyclinD1,MMP-9 and MMP-14,up-regula-ted the expression of Caspase-3 and Bax proteins,restrained the proliferation and invasion of CAL27 cells,and induced apoptosis.Inhibition of miR-337 expression reversed the silencing XIST on the proliferation and invasion of CAL27 cells,as well as the promo-ting effect on apoptosis.The double luciferase reporter gene experiment showed that XIST targeted down-regulation of miR-337,and miR-337 targeted negative regulation of ADAM28 expression.Conclusion:LncRNA XIST down-regulates miR-337 expression,up-regulates the expression of ADAM28,induces the proliferation and invasion of TSCC cells,and inhibits cell apoptosis.

[Objective]To investigate the non-suicidal self-injury(NSSI)behaviors in adolescents with depressive disorder,analyze related influencing factors,and provide theoretical basis and reference for the prevention and treatment of NSSI.[Methods]According to DSM-5 criteria,95 depressive adolescents were divided into two groups:one with NSSI(NSSI group)and one without NSSI(nNSSI group).All patients were assessed with Adolescent Non-suicidal Self-injury Assessment Questionnaire(ANSAQ),Self-Rating Depression Scale(SDS),Self-Rating Anxiety Scale(SAS),Simplified Coping Style Questionnaire(SCSQ),Experiences in Close Relationships-Relationship Structures Scale(ECR-RS),and Childhood Trauma Questionnaire-Short Form(CTQ-SF).The inter-group differences were compared.The influencing factors of NSSI were analyzed by using binary logistic regression.[Results]Of the 95 depressive adolescents,59 cases of NSSI were identified,with a detection rate of 62.11%.NSSI group had higher scores than nNSSI group on SDS,SAS,negative coping style,paternal attachment anxiety,maternal attachment anxiety and avoidance,CTQ-SF total score,emotional neglect,physical neglect,emotional abuse,and sexual abuse(all P<0.05).Binary logistic regression analysis showed that anxiety,negative coping style,maternal attachment avoidance and emotional abuse increased the risk of NSSI among adolescents with depressive disorders(all P<0.05).[Conclusions]Adolescents with depression have a high incidence of NSSI behaviors,which is related to anxiety,negative coping style,maternal attachment avoidance and emotional abuse.In addition to improving patients' depression and anxiety in clinical setting,attention should also be paid to patients' coping styles,parent-child relationship and childhood trauma to reduce the occurrence of NSSI behaviors.

Purpose To investigate the value of oxaliplatin-induced sinusoidal injury based on 3D CT image segmentation technology,and to analyze its variation.Materials and Methods A total of 24 patients with uneven hypoperfusion of liver parenchyma in the portal vein phase of enhanced CT after receiving oxaliplatin regimen chemotherapy from November 2019 to July 2021 in the Second Affiliated Hospital,Jiangxi Medical College,Nanchang University were analyzed,retrospectively.The imaging data of patients with epigastric CT enhancement before chemotherapy,early chemotherapy(1-3 cycles)and late chemotherapy(≥4 cycles)were collected.Two doctors used 3D Slicer software to segment and measure the liver volume and spleen volume at each stage on the CT image,as well as the hepatic hypoperfusion volume(HHV)of the liver in the portal vein phase after chemotherapy,and calculated the HHV ratio(HHVR),liver volume hepatomegaly rate and spleen volume splenomegaly rate,and performed statistical analysis.Results The ICC for HHV,liver volume and spleen volume measured by two doctors were 0.997(P=0.000),0.905(P=0.000)and 0.998(P=0.000),respectively.Reddish-brown could be used to represent normal liver parenchyma,and blue could be used to render the HHV area to achieve HHV visualization.There was a statistically significant increase in HHVR in the late stage of chemotherapy compared with the early stage of chemotherapy[(74.35±30.56)%vs.(57.15±30.53)%;t=3.226,P=0.004].In the early and late stages of chemotherapy,the liver volume and spleen volume increased statistically significantly compared with those before chemotherapy(all P<0.05),and the spleen volume splenomegaly rate value in the late stage of chemotherapy increased statistically compared with the early stage of chemotherapy[25.75(7.40,70.66)%vs.17.86(4.44,63.59)%;Z=2.229,P=0.026].The Pearson correlation coefficient between liver volume hepatomegaly rate and HHVR was 0.377(P=0.008),and the Spearman correlation coefficient between spleen volume splenomegaly rate and HHVR was 0.296(P=0.041).Conclusion The application of 3D CT image segmentation technology to measure the HHV caused by oxaliplatin has good consistency,and can realize the visual display of HHV.With the increase of chemotherapy cycle,the extent of oxaliplatin-induced sinusoidal injury shows an increasing trend,and is positively correlated with hepatomegaly and splenomegaly.

ObjectiveTo study the characteristics of the five tones of Parkinson's disease （PD） patients based on the theory of "five-viscera phonology"， and provide references for the syndrome differentiation and treatment of PD. MethodsA total of 272 cases of PD patients were collected as the PD group， and 240 individuals， including patient family members and hospital staff， were recruited as the control group. The 25-tone analyzer was used to collect the five-tone characteristics of both PD patients and control group participants. The participants were then stratified into three age groups， 41~55， 56~70， and 71~85 years old， and categorized by gender （male and female） for analysis. The frequency and composition ratio of the five tones were analyzed for both groups across the different age ranges and genders. Additionally， the average voice frequency of each participant was calculated to compare differences between groups， stratified by age range and gender. ResultsIn the 41~55 and 56~70 age groups， male participants in the PD group and the control group exhibited the highest frequency of Yu （羽） tone， with the PD group showing a significantly higher composition ratio of Yu tone compared to the control group （P＜0.05）； for males in the 56~70 age group， the composition ratios of Shang （商） and Zhi （徵） tone in the PD group were lower than those in the control group （P＜0.05）. For males in the 71~85 age group， both the PD group and the control group had the highest frequency of Yu tone， but there was no statistically significant difference in the composition ratios of the five tones between groups （P＞0.05）. For female participants in the PD group across all age groups， Yu tone was the most frequent， whereas for the control group， Jue （角） tone was the most frequent in all age groups， and the composition ratio of Yu tone in the PD group was significantly higher than that in the control group across all age groups （P＜0.05）； in the 56~70 age group， the composition ratio of Jue tone was lower in the PD group compared to that in the control group （P＜0.05）. Regarding voice frequency， males in the PD group aged 41~55 and 56~70 had higher voice frequency than those in the control group of the same age range， and similarly， females in the PD group aged 56~70 and 71~85 had higher voice frequency than their counterparts in the control group （P＜0.05）. ConclusionPD patients have a voice with a higher frequency and an increased proportion of Yu tone in their five-tone distribution. According to the theory of five-viscera phonology， PD patients may have disease mechanism of kidney essence deficiency.

OBJECTIVE To explore the impact of Shaoyao decoction on the intestinal microecology of rats with damp-heat diarrhea. METHODS Male SD rats were randomly divided into physiological group， model group， and Shaoyao decoction low-， medium- and high-dose groups （single dose of 5.62， 28.10 and 56.20 g/kg， by raw drugs）， with 7 rats in each group. Except for the physiological group， the remaining groups were all fed with high-sugar and high-fat diet， raised in a high-temperature and high- humidity environment， and administered white liquor and Escherichia coli suspension by gavage to establish a rat model of damp- heat diarrhea. On the second day after modeling， rats in each dosage group of Shaoyao decoction were administered the corresponding solution by gavage， once in the morning and once in the evening， for 3 consecutive days. After the last administration， fecal metagenomic sequencing analysis and biological information analysis were performed to detect the activities of intestinal cytochrome P450 （CYP） enzymes and intestinal flora metabolic enzymes. RESULTS There was no significant difference in the α diversity indexes of intestinal flora among the groups （P＞0.05）. The main phyla of rats in each group included Firmicutes， Actinobacteriota and Verrucomicrobiota， and the core dominant genera included Dubosiella， Lactobacillus and Romboutsia； low- ， medium- and high-dose of Shaoyao decoction could reverse the decrease in the relative abundance of Firmicutes， Romboutsia， Bifidobacterium and Monoglobus， as well as the increase in the relative abundance of Proteobacteria， Verrucomicrobiota， Escherichia-Shigella and Corynebacterium （P＜0.05）. Rats in each dosage group of Shaoyao decoction showed higher relative abundance of intestinal flora involved in carbon metabolism and cofactor biosynthesis pathways. Compared with the model group， the elimination rates of aminophenol and midazolam， as well as the concentration （except for the low-dose group） and metabolic rate of p-nitrophenol in rats of each dose group of Shaoyao decoction were significantly increased （P＜0.05）. CONCLUSIONS Shaoyao decoction can correct intestinal flora disorder in rats with damp-heat diarrhea， promote the recovery of intestinal CYP metabolic enzymes and intestinal flora metabolic enzymes， and thereby comprehensively improve intestinal microecology.

Objective To explore the influencing factors of coronary artery lesion severity in patients with acute coronary syndrome (ACS). Methods Clinical data of ACS patients admitted to Zhongshan Hospital, Fudan University from December 2017 to December 2019 were consecutively collected. The modified Gensini score was used to assess the severity of coronary artery lesions. Univariate and multivariate linear regression analyses were performed to identify independent factors associated with coronary artery lesion severity. Results A total of 1 689 ACS patients were included, with an average age of (64.04±11.45) years; 1 353 (80.11%) were male, and the mean modified Gensini score was (8.12±4.03). Multivariate linear regression analysis revealed that sex (β＝0.97, P＝0.001), age (β＝0.03, P＝0.021), estimated glomerular filtration rate (eGFR; β＝－0.03, P＜0.001), low-density lipoprotein cholesterol (LDL-C; β＝0.58, P＜0.001), apolipoprotein A1 (Apo A1; β＝－1.28, P＝0.012), lipoprotein(a) [Lp(a); β＝0.001, P＝0.033], and glycated hemoglobin A_1C (HbA_1C; β＝0.45, P＜0.001) were independent influencing factors of the modified Gensini score. Conclusions Metabolic indicators, including Apo A1, LDL-C, HbA_1C, and Lp(a), may serve as risk factors for coronary artery lesion severity in ACS patients, with Apo A1 demonstrating the strongest impact.

Osteoporosis and cardiovascular calcification,two major age-related chronic diseases that China is confronting today,pose serious threats to public health.Previous studies have reported overlapping connections in the pathological processes and molecular mechanisms of these two diseases,particularly concerning inflammation,oxidative stress,and dysregulation of mineral metabolism,and that these two diseases tend to share common pathogenic factors.However,research exploring the comorbidity mechanisms of the two diseases remains limited in both depth and scope,largely due to the lack of widely accepted comorbidity animal models.Herein,we analyzed the latest research findings on the comorbidity mechanisms of vascular calcification and osteoporosis,focusing on summarizing the animal disease models currently in extensive use and the relevant evaluation criteria.We aim to provide new references for comorbidity research models and offer scientific evidence for future studies on pathological mechanisms and the development of new therapeutic strategies.

Objective:To evaluate the clinical utility of dual-layer detector CT integrated with virtual monoenergetic imaging (VMI) and an orthopedic metal artifact reduction (O-MAR) algorithm in improving the image quality of patients after lumbar pedicle screw fixation surgery, and to analyze its impact on different types of artifacts and image quality of different tissues.Methods:The study was a prospective study, The study enrolled patients who underwent lumbar pedicle screw fixation at West China Hospital of Sichuan University between March and September 2024. All patients underwent lumbar CT scans using a dual-layer detector system, and four image sets were reconstructed. CLumbar routine scans were performed using dual-layer detector CT, and four image sets were reconstructed:onventional images (CI non-O-MAR), conventional images with O-MAR (CI O-MAR), virtual monoenergetic images (VMI non-O-MAR), and VMI with O-MAR (VMI O-MAR). Objective metrics including artifact index (AI), signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) were quantified, alongside subjective image quality assessment. One-way ANOVA or Friedman test were used to compare the objective evaluation indicators of image quality between VMI non-O-MAR and VMI O-MAR at different energy levels. Paired t-test or Wilcoxon signed-rank test was used for CI non-O-MAR/VMI non-O-MAR versus CI O-MAR/VMI O-MAR comparisons. Results:A total of 30 patients were included, and all underwent internal fixation with titanium alloy pedicle screws. Objective analysis revealed that in both high-and low-density artifact regions, the AI values of the VMI O-MAR group decreased with the increase of energy levels, and were significantly lower than those of the corresponding VMI non-O-MAR group, with a statistically significant difference (all P<0.001). When the energy level≥140 keV, the AI value of the VMI O-MAR group was simultaneously lower than that of the CI non-O-MAR group and the CI O-MAR group, with statistically significant differences (all P<0.05). The SNR and CNR on the vertebral bodies in the VMI non-O-MAR group and the VMI O-MAR group showed a decreasing trend with increasing energy levels, and were always lower than those in the CI group at high energy levels (100-180 keV) (all P<0.05). At high energy levels (100-180 keV), the SNR of VMI O-MAR in the intervertebral disc and intraspinal tissues was higher than that of the VMI non-O-MAR group, with statistically significant differences (all P<0.05). Compared to other groups, subjective analysis indicated that the 140 keV VMI combined with O-MAR group received the highest image quality scores ( P<0.05). Conclusions:The combined application of VMI and O-MAR technology effectively reduces metal artifacts in post-lumbar fixation CT images. The 140 keV VMI with O-MAR reconstruction provides superior image quality and enhances diagnostic confidence.

Objective To observe the value of prenatal ultrasound graded management of Sylvian fissure for diagnosing fetal lissencephaly.Methods Totally 39 fetuses with MRI diagnosed lissencephaly who underwent prenatal ultrasound examination were retrospectively enrolled and divided into non-graded management group(n=20)and graded management group(n=19)according to prenatal ultrasound examination before or after the application of prenatal ultrasound graded management of Sylvian fissure(i.e.prenatal ultrasound routine screening for fetal Sylvian fissure morphology).The diagnosis of prenatal ultrasound were compared and analyzed between groups,and the diagnostic value of graded management was evaluated.Results Among 20 fetuses in non-graded management group,prenatal ultrasound showed lissencephaly in 4 fetuses,but only other structural abnormalities in 16 fetuses.Then the latter were re-evaluated based on prenatal ultrasound graded management of Sylvian fissure,among which 4 fetuses could not be evaluated since not standard ultrasonic section,2 fetuses with severe hydrocephalus and Sylvian fissure could not be seen,while Sylvian fissure morphology did not match the corresponding gestational week in 4 fetuses,and type Ⅰ(no platform type)and type Ⅴ(Z-shaped)were noticed in 5 and 1 fetus,respectively.In graded management group,prenatal ultrasound indicated 15 fetuses with lissencephaly,including Sylvian fissure morphology did not match the corresponding gestational week in 6 fetuses,type Ⅰ(no platform type),type Ⅲ(linear type)and type Ⅴ(Z-shaped)were detected in 7,1 and 1 fetus,respectively,while no clear diagnosis was obtained in 4 fetuses.Prenatal ultrasound detection rate of fetal lissencephaly in graded management group(15/19,78.95％)was significantly higher than that in non-graded management group(4/20,20.00％)(P＜0.01).Conclusion Based on graded management of Sylvian fissure could improve the efficiency of prenatal ultrasound for diagnosing fetal lissencephaly.
