OBJECTIVE:Anterior cervical decompression and fusion is a classic surgical method for the treatment of degenerative cervical spondylosis.The use of nail plates increases the fusion rate and stability and indirectly leads to adjacent vertebral degeneration and postoperative dysphagia.In this paper,the clinical results and complications of ROI-CTM self-locking system and traditional cage combined with screw-plate internal fixation in the treatment of degenerative cervical spondylosis were compared by meta-analysis to provide evidence-based support for the selection of internal fixation methods in anterior cervical decompression and fusion. METHODS:CNKI,WanFang,VIP,PubMed,Cochrane Library,Web of Science,and Embase databases were searched for Chinese and English literature on the application of ROI-CTM self-locking system and fusion cage combined with screw plate internal fixation in the treatment of degenerative cervical spondylosis.The retrieval time range was from inception to July 2023.Two researchers selected the literature strictly according to the inclusion and exclusion criteria.The Cochrane bias risk tool was used to evaluate the quality of randomized controlled trials.Newcastle-Ottawa Scale was used to assess the quality of cohort studies.Meta-analysis was performed using RevMan 5.4 software.Outcome indicators included operation time,intraoperative blood loss,Japanese Orthopaedic Association score,Neck Disability Index,C2-C7 Cobb angle,fusion rate,incidence of adjacent vertebral degeneration,cage subsidence rate,and incidence of dysphagia. RESULTS:Thirteen articles were included,including eleven retrospective cohort studies and two randomized controlled trials,with 1 136 patients,569 in the ROI-C group,and 567 in the cage combined with the nail plate group.Meta-analysis results showed that the operation time(MD=-15.52,95%CI:-18.62 to-12.42,P<0.000 01)and intraoperative blood loss(MD=-24.53,95%CI:-32.46 to-16.61,P<0.000 01)in the ROI-C group and the fusion device combined with nail plate group.Postoperative adjacent segment degeneration rate(RR=0.40,95%CI:0.27-0.60,P<0.000 01)and postoperative total dysphagia rate(RR=0.18,95%CI:0.13-0.26),P<0.000 01)were statistically different.The two groups had no significant difference in Japanese Orthopaedic Association score,Neck Disability Index,C2-C7 Cobb angle,fusion rate,or cage subsidence rate(P≥0.05). CONCLUSION:Applying an ROI-CTM self-locking system and traditional cage combined with plate internal fixation in anterior cervical decompression and fusion can achieve satisfactory clinical results in treating degenerative cervical spondylosis.The operation of the ROI-CTM self-locking system is more straightforward.Compared with a cage combined with plate internal fixation,the ROI-CTM self-locking system can significantly reduce the operation time and intraoperative blood loss and has obvious advantages in reducing the incidence of postoperative dysphagia and adjacent segment degeneration.The ROI-CTM self-locking system is recommended for patients with skip cervical spondylosis and adjacent vertebral disease.However,given its possible high settlement rate,using a fusion cage combined with screw-plate internal fixation is still recommended for patients with degenerative cervical spondylosis with multiple segments and high-risk factors of fusion cage settlement,such as osteoporosis and vertebral endplate damage.

BackgroundPatients with depressive disorder often exhibit impaired decision-making functions. However， the relationship between decision-making abilities and depressive and anxiety symptoms in these patients remains unclear. ObjectiveTo explore the characteristics of decision-making behavior in patients with depressive disorder， and to analyze its relationship with clinical symptoms. MethodsA total of 48 patients diagnosed with depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） were recruited from the Department of Psychosomatic Medicine of the Affiliated Hospital of Southwest Medical University from October 2020 to May 2023. Concurrently， 52 healthy individuals matched for age and gender were recruited from Luzhou as the control group. Beck Depression Inventory （BDI） and Beck Anxiety Inventory （BAI） were used for assessment， and decision-making behavior was evaluated using Probabilistic Reversal Learning （PRL） task. Indicators assessed included the number of trials to criterion， perseverative errors， win-stay rate and lose-shift rate. Spearman correlation analysis was used to assess the correlation between BDI and BAI scores and PRL task indicators. ResultsThe depression group showed a significantly higher lose-shift rate compared with the control group （t=3.684， P<0.01）. There were no statistically significant differences between two groups in trials to criterion， perseverative errors and win-stay rate （t=0.329， 0.132， 0.609， P>0.05）. In depression group， BDI and BAI scores were positively correlated with the win-stay rate（r=0.450， 0.398， P<0.01）. ConclusionPatients with depressive disorder are more likely to change their decision-making strategies following negative outcomes. Furthermore， the severity of depressive and anxiety symptoms is associated with a greater propensity to maintain existing decisions after receiving positive feedback. ［Funded by 2019 Joint Project of Luzhou Science and Technology Bureau-Southwest Medical University （number， 2019LZXNYDJ39］

BackgroundWith the rapid development of the networking technologies， internet addiction has increasingly become a serious mental health issue. Previous studies have revealed the link between childhood trauma and internet addiction， while the mediating role of perceived stress in this link is not yet clear. ObjectiveTo investigate the role of medical students' perceived stress in the relationship between childhood trauma and internet addiction， so as to provide references for the intervention of internet addiction. MethodsFrom February to March 2023， a random sampling technique was used to select 1 232 undergraduate students from the School of Clinical Medical Sciences of Southwest Medical University as research subjects. The Childhood Trauma Questionnaire-Short Form （CTQ-SF）， Perceived Stress Scale （PSS）， Internet Gaming Disorder Scale （IGDS）， and Bergen Social Media Addiction Scale （BSMAS） were used for assessment. Pearson's correlation coefficients were calculated. The mediation effect of perceived stress in the relationship between childhood trauma and internet addiction was tested using Model 4 in the SPSS Process 4.1， and Bootstrapping procedure involving 5 000 replicates was employed to confirm the statistical significance. ResultsA total of 1 016 （82.47%） valid completed questionnaires were gathered. The CTQ-SF scores of medical students were positively correlated with PSS scores， IGD scores， and BSMAS scores （r=0.583， 0.474， 0.465， P<0.01）. PSS scores were positively correlated with IGD scores and BSMAS scores （r=0.369， 0.479， P<0.01）. Childhood trauma in medical students was found to positively predict perceived stress （β=0.191， P<0.01）， social media addiction （β=0.160， P<0.01）， and internet gaming disorder （β=0.106， P<0.01）. Perceived stress played a significant mediating role in the relationship between childhood trauma and internet gaming disorder， indirect effect value was 0.018 （95% CI： 0.009~0.027）， accounting for 16.98%. Perceived stress also exhibited a significant mediating role in the relationship between childhood trauma and social media addiction， indirect effect value was 0.063 （95% CI： 0.048~0.079）， accounting for 39.38%. ConclusionChildhood trauma in medical students may affect internet gaming disorder and social media addiction through perceived stress. ［Funded by 2022 Annual Research Project of Sichuan Applied Psychology Research Center，（number，CSXL-22102）］

Objective: Self-determination theory (SDT) deems that people have three causality orientations: autonomy orientation, control orientation, and impersonal orientation. Previous studies suggested that lower autonomy orientation or higher control and impersonal orientations may be associated with more addictive behaviors. Our study aimed to investigate if these associations exist in Internet gaming disorder (IGD), and if sensation seeking, anxiety, and depression could influence the associations between causality orientations and IGD symptoms. Methods: A total of 1,400 college students completed the Internet Gaming Disorder Scale, General Causality Orientation Scale, Brief Sensation Seeking Scale, Generalized Anxiety Disorder Scale, and Patient Health Questionnaire. Correlation, multiple linear regressions, structural equation model (SEM) analyses, and moderation analyses were conducted to explore the associations. Results: The control and impersonal orientations were positively associated with IGD symptoms, while the autonomy orientation was negatively associated with them. Moreover, SEM analyses showed that the autonomy-IGD relationship was totally mediated by anxiety and depression, the impersonal-IGD relationship was partially mediated by anxiety, and the control-IGD relationship was partially mediated by depression. Finally, the effects of causality orientations on IGD were moderated by sensation seeking. Conclusion Overall, autonomy orientation is linked to fewer gaming problems, whereas control and impersonal orientations are associated with more gaming problems. Moreover, the relationships between causality orientations and IGD symptoms are mediated by anxiety and depression and moderated by sensation seeking. Our findings inform theory on the motivations of gaming behaviors and may shed light on the prevention and intervention of IGD from the perspective of SDT.

Objective:To investigate the risk of new-onset stroke caused by cerebral microbleed (CMB) and asymptomatic lacunar infarction (ALI) and their risk factors.Methods:A prospective observational study over a 18 month period was conducted on 397 non stroke patients who visited the Affiliated Hospital of Xuzhou Medical University from March 2020 to June 2022. By the presence of CMB and ALI about magnetic resonance imaging, they were divided into th control group (without CMB and ALI, 117 cases, 29.5%), ALI group (101 cases, 25.4%), CMB group (89 cases, 22.4%) and CMB-ALI group (90 cases, 22.7%).They were followed up for 18 months, the risk factors for CMB, ALI, and the risk of new stroke were analyzed.Results:The systolic blood pressure and uric acid in the CMB group were higher than those in the control group: (155.2 ± 24.2) mmHg(1 mmHg = 0.133 kPa) vs. (138.2 ± 19.0) mmHg, (387.0 ± 28.3) μmol/L vs. (354.0 ± 21.5) μmol/L, there were statistical differences ( P<0.05). After followed up for 18 months, the incidence rate of cerebral infarction, cerebral hemorrhage and TIA in the CMB group and CMB-ALI group were higher than those in the control group: 13.5%(12/89), 13.3%(12/90) vs.5.1%(6/117); 9.0%(8/89), 10.0%(9/90) vs. 2.6%(3/117); 5.6%(5/89), 6.7%(6/90) vs. 0.8%(1/117), there were statistical differences ( P<0.05). Conclusions:CMB is prone to abnormal systolic blood pressure and uric acid. CMB, CMB-ALI are prone to new onset ischemic stroke, cerebral hemorrhage and TIA.

Recent trends suggest that Chinese herbal medicine formulas(CHM formulas)are promising treatments for complex diseases.To characterize the precise syndromes,precise diseases and precise targets of the precise targets between complex diseases and CHM formulas,we developed an artificial intelligence-based quantitative predictive algorithm(DeepTCM).DeepTCM has gone through multilevel model cali-bration and validation against a comprehensive set of herb and disease data so that it accurately captures the complex cellular signaling,molecular and theoretical levels of traditional Chinese medicine(TCM).As an example,our model simulated the optimal CHM formulas for the treatment of coronary heart disease(CHD)with depression,and through model sensitivity analysis,we calculated the balanced scoring of the formulas.Furthermore,we constructed a biological knowledge graph representing interactions by associating herb-target and gene-disease interactions.Finally,we experimentally confirmed the thera-peutic effect and pharmacological mechanism of a novel model-predicted intervention in humans and mice.This novel multiscale model opened up a new avenue to combine"disease syndrome"and"macro micro"system modeling to facilitate translational research in CHM formulas.

AIM:To investigate the interaction mechanisms of estrogen receptor β(ERβ),nuclear factor-κB(NF-κB)and activator protein-1(AP-1)in colorectal cancer by analyzing the transcriptome data after tumor necrosis fac-tor α(TNF-α)treatment and combining it with NF-κB/p65 and ERβ cistrome data in colon cancer cell lines HT29 and SW480.METHODS:The TNF-α transcriptome was integrated with p65 and ERβ cistrome data.Protein interaction net-works of TNF-α,NF-κB/p65 and ERβ were constructed in colon cancer cell lines HT29 and SW480 using R.RE-SULTS:TNF-α regulated genes through p65 DNA binding,which were mainly enriched in the NF-κB and mitogen-acti-vated protein kinase(MAPK)pathways.Components of the NF-κB/p65 and MAPK pathways had potential interactions with AP-1 family proteins.ERβ overexpression did not significantly affect TNF-α-mediated gene regulation but may regu-late AP-1 activity through the MAPK and phosphatidylinositol 3-kinase(PI3K)/Akt pathways.Furthermore,ERβ de-creased p65 DNA binding sites in HT29 but increased p65 binding sites in SW480,suggesting cell line-specific regulation of NF-κB by ERβ.CONCLUSION:In colorectal cancer,NF-κB,ERβ and AP-1 have potential interactions:TNF-α can regulate AP-1 through NF-κB,while ERβ overexpression can alter NF-κB-mediated regulation,and the influence of ERβ on NF-κB may be gender-related.

Objective To explore the genetic polymorphism and mutation rate of 36 Y-STR loci in Sichuan Han population and provide basic data for their forensic applications.Methods Blood samples were collected from 307 unrelated male individuals and 367 father-son pairs in Sichuan Han population using FTA blood sampling cards.The Y41SE-v1.2 kit was used to type 36 Y-STR loci,and the population genetic parameters and mutation rates of each locus were calculated.The genetic relationship between Sichuan Han population and other ethnic populations was analyzed in combination with 19 other populations in China.Results A total of 79 mutations were observed in 36 Y-STR loci in 367 father-son pairs of Sichuan Han population,with an average mutation rate of 6.00×10-3.There were 74(93.67%)one-step mutations and 5(6.33%)multi-step mutations.A total of 383 alleles were found at 36 Y-STR loci in 307 Sichuan Han males.The number of alleles at each locus ranged from 5(0.016 29)to 56(0.182 41),GD ranged from 0.100 02(DYS645)to 0.959 99(DYS385),and 306 haplotypes were found.The HD,DC and HMP values were 0.999 973,99.67%and 0.003 284,respectively.The results of genetic distance(Fst)analysis showed that the Sichuan Han population had the closest genetic distance with the Chongqing Han population(0.000 9)and the furthest genetic distance with the Xinjiang Mongolian group(0.032 0).The MDS based on genetic distance was basically consistent with the results of cluster analysis.Conclusion The 36 Y-STR loci have high genetic polymorphism in the Sichuan Han population.The study data can provide data support for the construction of the Y-STR database in this region,and also provide basic genetic information for forensic investigation and population genetics research.

Objective:To explore the causes of self-management dilemma in young and middle-aged patients with recurrent acute pancreatitis from the perspectives of nurses, patients and patient caregivers, in order to provide reference for developing self-management intervention plans that meet the needs of patients.Methods:Using the descriptive phenomenological methods from qualitative research, 15 patients with recurrent acute pancreatitis, six nurses and nine caregivers from the Hepatobiliary Pancreatic Surgery Ward of the Second Norman Bethune Hospital of Jilin University from November 2021 to December 2022 were selected for semi-structured in-depth interviews. The Colaizzi 7-step method was used to analyze and refine the theme.Results:Two main themes were extracted to explain the difficulties in self-management of young and middle-aged patients with recurrent acute pancreatitis. The internal reasons for the self-management dilemma included cognitive biases in the importance of self-management, limited access to self-management knowledge and negative attitudes towards self-behavior management, and the external reasons for self-management dilemma included insufficient inclusiveness of the external environment towards diseases, fear of disease progression, multiple burdens caused by diseases and busy work.Conclusions:Young and middle-aged patients with recurrent acute pancreatitis experience multiple difficulties in the process of self-management. Clinical medical staff should explore self-management models with contemporary characteristics, enhance patient self-management ability and quality of life, reduce disease recurrence rate.
