Background: and Purpose This study aimed to investigate the association between residual inflammatory risk (RIR) and vulnerable plaques using high-resolution magnetic resonance imaging (HRMRI) in symptomatic intracranial atherosclerotic stenosis (ICAS). Methods: This retrospective study included 70%–99% symptomatic ICAS patients hospitalized from January 2016 to December 2022. Patients were classified into four groups based on high-sensitivity C-reactive protein (hs-CRP) and low-density lipoprotein cholesterol (LDL-C): residual cholesterol inflammatory risk (RCIR, hs-CRP ≥3 mg/L and LDL-C ≥2.6 mmol/L), RIR (hs-CRP ≥3 mg/L and LDL-C <2.6 mmol/L), residual cholesterol risk (RCR, hs-CRP <3 mg/L and LDL-C ≥2.6 mmol/L), and no residual risk (NRR, hs-CRP <3 mg/L and LDL-C <2.6 mmol/L). Vulnerable plaque features on HRMRI included positive remodeling, diffuse distribution, intraplaque hemorrhage, and strong enhancement. Results: Among 336 included patients, 21, 60, 58, and 197 were assigned to the RCIR, RIR, RCR, and NRR groups, respectively. Patients with RCIR (adjusted odds ratio [aOR], 3.606; 95% confidence interval [CI], 1.346–9.662; P=0.011) and RIR (aOR, 3.361; 95% CI, 1.774–6.368, P<0.001) had higher risks of strong enhancement than those with NRR. Additionally, patients with RCIR (aOR, 2.965; 95% CI, 1.060–8.297; P=0.038) were more likely to have intraplaque hemorrhage compared with those with NRR. In the sensitivity analysis, RCR (aOR, 2.595; 95% CI, 1.201–5.608; P=0.015) exhibited an additional correlation with an increased risk of intraplaque hemorrhage. Conclusion In patients with symptomatic ICAS, RIR is associated with a higher risk of intraplaque hemorrhage and strong enhancement, indicating an increased vulnerability to atherosclerotic plaques.

Childhood household dysfunction(CHD)is a common adverse childhood experience,which brings the heavy physical and mental afflictions to children and adolescents.Trauma-focused cognitive behavioral therapy(TF-CBT)is an evidence-based psychotherapy that helps children and adolescents who have experienced childhood trauma with traumatic memories.It aims to enhance the coping abilities of CHD children and adolescents,thereby improving the negative effects caused by trauma and effectively reducing psychological burden.TF-CBT can effectively improve post-traumatic stress disorder,emotional and behavioral problems,and family function in children and adolescents with CHD.It is recommended to conduct high-quality original research in the future,develop targeted TF-CBT intervention plans based on potential predictive factors,adopt a combination of online and offline methods,and construct TF-CBT interventions suitable for the Chinese CHD population to meet the mental health service needs of CHD children and adolescents.

Objective To observe the residual of lumbago and leg pain with contained type(CT)and non-contained type(NCT)lumbar disc herniation(LDH)after transforaminal endoscopic treatment,and to explore the role of hypoxia-inducible factor-1α(HIF-1α)and transient receptor potential vanillate 1(TRPV1)pathway.Methods A total of 68 single-segment LDH patients were selected from July 2021 to October 2022,including 44 males and 24 females;aged 26 to 67 years old with an av-erage of(43.63±11.94)years old;course of disease was 4 to 36(18.91±10.34)months;body mass index was(24.45±4.00)kg·m-2;there were 7 cases of L3.4 segments,32 cases of L4,5 segments,and 29 cases of L5S1 segments.All of them were per-formed with percutaneous intervertebral endoscopic extraction of nucleus pulposus and were divided into contained group(CT group)and non-contained group(NCT group)with 34 cases respectively according to the integrity of outer layer of fibrous an-nulus observed during operation.A total of 17 patients who underwent open surgery for scoliosis or vertebral fracture were se-lected as control group,including 12 males and 5 females;aged 21 to 65 years old with an average of(39.41±12.80)years old;body mass index was(24.86±4.11)kg·m-2.The relative mRNA expression quantity of HIF-1α,TRPV1 in nucleus pulposus were measured by quantitative real-time PCR.The contents of neurokinin 1 receptor(NK1R),nerve growth factor(NGF),vascular endothelial growth factor(VEGF)in nucleus pulposus and the serum substance P(SP)and calcitonin gene-related peptide(CGRP)were detected by enzyme linked immunosorbent assay(ELISA).The threshold of lumbar tenderness was de-tected by a pressure pain meter.The degree of lumbago and lumbar function were evaluated by visual analog scale(VAS)and Oswestry disability index(ODI)separately.The residual rate of postoperative lumbago and leg pain was assessed.Results The mRNA relative expression quantity of HIF-1α and TRPV1,and the contents of NK1R,NGF and VEGF in nucleus pulposus,and the levels of serum SP and CGRP before surgery in the NCT group were higher than those in the CT group(P＜0.05),and those in the CT group were higher than the control group(P＜0.05).At day 7 after surgery,the serum SP and CGRP levels,lum-bago and leg pain VAS scores and lumbar ODI index in two LDH groups were lower than before surgery(P＜0.05),and those in the NCT group were higher than the CT group(P＜0.05),and the threshold of lumbar tenderness in the NCT group was lower than the CT group(P＜0.05).The differences of lumbago and leg pain VAS scores,lumbar ODI index and lumbar tenderness threshold between preoperative and postoperative 7 days in the NCT group were lower than those in the CT group(P＜0.05).The residual rate of lumbago and leg pain at 7 days after surgery in the NCT group was higher than that in the CT group(P＜0.05).Conclusion HIF-1α and TRPV1 pathway promoted the excessive production of NGF,VEGF,NK1R in nucleus pulposus and serum neuropeptides SP and CGRP,which may lead to the higher residual rate of lumbago and leg pain with non-contained lumbar disc herniation postoperative.

Objectives:To present the epidemiological characteristics of stroke incidence and stroke-related mortality among the whole population in national cardiovascular disease surveillance areas from 2015 to 2019. Methods:Data of stroke incidence and stroke-related mortality from 2015 to 2019 were collected from the China Registry of Cardiovascular Events(China RACE),which was established in 2014,covering 100 counties(cities,districts)in 31 provinces in China.The Joinpoint model was used to analyze the annual percentage changes(APC)and trends of stroke incidence rate.The age-standardized incidence rate(ASIR)was calculated using the Seventh National Census data as the standard population.With annual reported stroke events and stroke-related deaths,the mortality to incidence ratio(M/I)were examined. Results:From 2015 to 2019,an increase of 9.41%(APC=2.12%,95%CI:1.43%-2.82%,Ptrend<0.01)resulted in the overall stroke crude incidence rate(CIR)of 468.48/100 000 in 2019 among the whole population,with relatively higher in male and in rural area.The more sharply elevating of CIR appeared in males(11.26%[APC=2.53%,95%CI:1.83%-3.24%,Ptrend<0.01])rather than in females(7.26%[APC=1.63%,95%CI:0.81%-2.46%,Ptrend<0.01]).Meanwhile,the general ASIR decreased 7.47%(APC=-1.72%,95%CI:-3.23%--0.20%,Ptrend<0.05),reaching 523.82/100 000 in 2019.The females generally showed significant descending trend(9.56%[APC=-2.27%,95%CI:-3.99%--0.52%,Ptrend<0.05]),as well as more reduction than that in the males(15.82%vs.11.40%)in urban area.The crude incidence rate of stroke increased with age.From 2015 to 2019,the CIR in 45-49 age group increased 12.48%(APC=3.18%,95%CI:1.67%-4.72%,Ptrend<0.01),compared with an reduction of 15.76%(APC=-4.39%,95%CI:-7.63%--1.04%,Ptrend<0.05)in 80-84 age group.Over the monitoring years,the overall M/I was 0.19,with an age-specific U-shaped distribution.The lowest of M/I(0.10)appeared in those aged 50-54 and 55-59,while the highest(0.45)detected in those aged 85 and over.The M/I of all age in urban areas were consistently lower than that in rural areas. Conclusions:Stroke incidence burden increased from 2015-2019 in the national surveillance areas in China,along with the unfavorable geographic diversity and age-specific divergence.Further efforts are required to improve health care covering all ages and regions in China to reduce the incidence of stroke and stroke-related mortality.

Objectives:The present study aims to investigate the incidence and mortality feature of acute myocardial infarction(AMI)from 2015 to 2019 in China by utilizing national registry data. Methods:Data of AMI incidence and mortality in the surveillance area during 2015 to 2019 were abstracted from China Registry of Acute Cardiovascular Event(China RACE),which was established in 100 counties from 31 provincial regions in China.Incidence rate,age standardized incidence rate(ASIR)and mortality to incidence ratio(M/I)was estimated in AMI cases.A Joinpoint regression was executed and annual percent change(APC)was examined to identify trends in incidence. Results:From 2015 to 2019,a total of 257 686 acute myocardial infarction incidence and 149 169 deaths were registered.The annual incidence rate of AMI in 2019 was 82.76 per 100 000.Over the study period,the incidence rate of AMI increased by 6.05%for men(APC=1.30%,95%CI:0.56%to 2.02%)but decreased by 11.80%for women(APC=-3.10%,95%CI:-4.54%to-1.68%),resulting a steady trend for AMI crude incidence rate for the overall population.The overall ASIR of AMI declined by 16.59%(APC=-4.32%,95%CI:-5.32%to-3.34%)from 113.68 per 100 000 in 2015 to 94.82 per 100 000 in 2019.The ASIR of AMI declined by 11.04%(APC=-2.72%,95%CI:-3.78%to-1.67%)for men,23.96%(APC=-6.56%,95%CI:-8.57%to-4.58%)for women,12.57%(APC=-3.08%,95%CI:-6.01%to-0.08%)for the urban areas,and 19.24%(APC=-5.18%,95%CI:-10.19%to 0.03%)for rural areas respectively.The incidence rate of AMI increases gradually with age in both men and women.The incidence of AMI in urban men of 35-44 and 45-54 year age groups increased by 77.16%(APC=13.52%,95%CI:3.29%to 24.57%)and 26.36%(APC=5.71%,95%CI:-0.95%to 12.68%)over time.However,the incidence of AMI fell in the population above 65 year old,by 26.58%(APC=-6.68%,95%CI:-11.98%to-1.01%),19.85%(APC=-5.64%,95%CI:-11.57%to 0.65%)and 14.53%(APC=-4.44%,95%CI:-7.75%to-1.04%)in the 65-74 year age,75-84 year age and≥85year age groups respectively from 2015 to 2019.The mortality to incidence ratio of AMI was 0.58 over time,higher in women than in men,and higher in rural areas than in urban areas.The M/I ratio of AMI decreased from 0.62 in 2015 to 0.52 in 2019(APC=-4.28%,95%CI:-5.75%to-2.83%).There was a declined trends in M/I of AMI in urban residents of both male and female,and in the rural male residents(all P<0.05),while a steady trend in the rural female residents(P>0.05). Conclusions:The overall incidence of AMI remains steady during 2015 to 2019 in the national surveillance areas in China.Yet,downward trends in elder and female residents and increased trend in middle-aged urban males in AMI incidence are observed.The mortality of AMI in these period are age,sex and urban-rural dependent.Targeted mitigation strategies on AMI prevention and treatment need to be strengthened to reduce its incidence and mortality.

BackgroundThe prevalence of depressive disorder in adolescents is on the rise. There have been studies on the pairwise relations between dysfunctional attitude， negative automatic thoughts， positive coping style and depressive symptoms in the past. However， the impact of the intrinsic relations among dysfunctional attitude， negative automatic thoughts and positive coping style on depressive symptoms is still unclear. ObjectiveTo explore the influence of dysfunctional attitude on adolescent depressive symptoms and examine the action path of negative automatic thoughts and positive coping style on it， in order to provide references for intervention for adolescent patients with depressisve disorder. MethodsThis study involved 162 adolescent patients with depressive disorder， who met the diagnostic criteria for depressive episodes in the International Classification of Diseases， 10th edition （ICD-10） and received treatment in Taiyuan Psychiatric Hospital from October 1， 2022 to October 31， 2023. These patients were evaluated using Self-rating Depression Scale （SDS）， Dysfunction Attitude Scale （DAS）， Positive Coping Style Subscale in Simplified Coping Style Questionnaire（SCSQ） and Automatic Thoughts Questionnaire （ATQ）. Pearson correlation analysis was adopted to examine the correlation among scores of scales above. Model 6 in Process 3.4.1 was adopted to test the acting path of negative automatic thoughts and positive coping style between dysfunctional attitude and adolescent depression symptoms. ResultsA total of 148 adolescent patients with depressive disorder completed an effective questionnaire survey， with a response rate of 91.36%. The direct effect value of dysfunctional attitude on depressive symptoms was 0.423 and the effect size was 63.32%. Negative automatic thoughts and positive coping style affected as acting path between dysfunctional attitude and depressive symptoms， with effect values of 0.156 （accounting for 23.35% of the total effect） and 0.045 （accounting for 6.74% of the total effect） respectively. Meanwhile， negative automatic thoughts and positive coping style affected as a chain reaction pathway between dysfunctional attitude and depressive symptoms， with an effect value of 0.044， accounting for 6.59% of the total effect. ConclusionDysfunctional attitude can not only directly affect the depressive symptoms of adolescent patients with depressive disorder， but also affect the depressive symptoms of adolescent patients with depressive disorder through the independent path or chain path of negative automatic thoughts and positive coping style.

Nanozymes, a groundbreaking discovery by Chinese scientists, represent a novel and remarkable property of nanomaterials. They not only exhibit catalytic activity comparable to natural enzymes, but also boast exceptional stability, tunable reactivity, and the ability to catalyze reactions under mild conditions. The identification of nanozymes has unveiled the biocatalytic potential of inorganic nanomaterials. In parallel, inorganic minerals have long been regarded as pivotal catalysts in the origin of life, driving the synthesis of early biomolecules. These minerals not only facilitate redox reactions that convert simple inorganic compounds into organic molecules but also enable chiral selection, the synthesis of biomacromolecules, and radioprotective functions via their surface structures. Recent advances suggest that inorganic nanomaterials can delicately catalyze the formation of biomolecules, aid in macromolecular assembly, and provide radiation shielding. Furthermore, nanominerals are found in abundance across Earth and extraterrestrial environments. This paper seeks to explore the potential of nanozymes as catalytic agents in the processes that gave rise to life, integrating the catalytic roles of inorganic minerals with the unique attributes of nanozymes, which will provide a new perspective for research of origin of life.

Objective:To understand the baseline viral load (VL) of newly reported HIV- infected patients before antiretroviral therapy and related factors in Tianjin.Methods:Data were obtained from the China Disease Control and Prevention Information System, and the study subjects were HIV-infected patients before the first antiretroviral therapy in Tianjin from 2019 to 2022, and the information about their socio-demographic characteristics, baseline CD4 +T lymphocyte (CD4) counts before antiretroviral therapy and baseline VL test results were collected, the baseline high VL was defined as ≥100 000 copies/ml. The effect of different factors on viral load were analyzed. Software SPSS 24.0 was used for statistical analysis. Results:A total of 1 296 newly reported HIV-infected patients were included in the study, in whom 15.89% (206/1 296) had high baseline VL, and multifactorial logistic regression analysis showed that those with history of STD (a OR=1.45, 95% CI:1.00-2.08) were more likely to have high baseline VL. Compared with those with baseline CD4 counts <200 cells/μl, those with baseline CD4 counts 200-350 cells/μl (a OR=0.40, 95% CI: 0.27-0.57), 351-500 cells/μl (a OR=0.32, 95% CI: 0.20-0.49), and >500 cells/μl (a OR=0.30, 95% CI: 0.18-0.49) were less likely to have high baseline VL. Conclusions:The proportion of HIV-infected patients with high baseline VL before antiretroviral therapy was low in Tianjin during 2019-2022. History of STD and baseline CD4 counts <200 cells/μl were associated with high baseline VL in HIV-infected patients, to which close attention needs to be paid in AIDS prevention and control.
