Anticipatory anxiety is a negative emotion that arises when individuals encounter potential threats or uncertainties in the future. It is the core symptom of a variety of anxiety disorders, and is closely associated with the occurrence, severity, treatment outcome, and prognosis of anxiety disorders, which has garnered a growing amount of focus in clinical practice. Nevertheless, scientific research on anticipatory anxiety continues to face obstacles such as unclear pathological mechanisms, the absence of simple and consistent self-assessment tools, and effective interventions. To improve understanding of the role of anticipatory anxiety in the diagnosis and treatment of anxiety disorders, this study reviews pertinent domestic and international literature, and briefly introduces the concept, assessment and measurement, activation paradigm, pathological mechanisms, and interventions of anticipatory anxiety.

Objective:To investigate the safety and efficacy of Pipeline embolization device (PED) Shield in intracranial unruptured saccular aneurysms.Methods:This is a retrospective cohort study; 124 patients with intracranial unruptured saccular aneurysms treated with PED Shield at Department of Cerebrovascular Surgery, Neurosurgery Center, Zhujiang Hospital, Southern Medical University from July 2023 to October 2024 were enrolled. Intraoperative device-related complications and occurrence of hemorrhagic and ischemic complications within 30 days of the procedure were recorded. The clinical results and imaging results (degrees of stent patency and aneurysm occlusion rate) 6 months after follow-up were statistically analyzed. Modified Rankin scale (mRS) score>2 was defined as poor prognosis in clinical follow-up, and grade D according to O'Kelly Marotta (OKM) classification was considered as complete aneurysm occlusion in imaging follow-up.Results:Eighty-seven females and 37 males, aged (56.44±12.17) years (ranging from 27 to 80 years) were enrolled, with a maximum aneurysm diameter of 5.12 (3.73, 7.24) mm. Among the 124 patients, incidence of intraoperative instrument-related complications was 6.5% (8/124); and within 30 days of the procedure, incidence of ischemic complications was 4.8% (6/124) and that of hemorrhagic complications was 1.6% (2/124). Eighty-four patients had a 6-month clinical follow-up, with 1 patient (1.2%) having poor prognosis. Eighty-four patients (67.7%) completed a 6-month imaging follow-up: complete occlusion rate of aneurysms was 82.1% (69/84), incidence of in-stent stenosis (stenosis degree ≥25%) was 4.8% (4/84), and no symptomatic in-stent stenosis was found.Conclusion:Result of this study shows that PED Shield may be an effective and safe clinical option for intracranial unruptured saccular aneurysms.

Background: and Purpose Collateral circulation is considered an important factor affecting the risk of stroke, but the factors that affect collateral circulation remain unclear. This study was performed to identify the factors associated with collateral circulation, especially blood lipids. Methods: The study involved patients who had undergone digital subtraction angiography and were confirmed as having severe unilateral stenosis or occlusion of the internal carotid artery (ICA). We classified the collateral circulation status of each patient as good (Grade 3 or 4) or poor (Grade 0, 1, or 2) according to the grading system of the American Society of Interventional and Therapeutic Neuroradiology/American Society of Interventional Radiology. We collected data on patients’ characteristics and identified the factors that affect collateral circulation. Results: This study included 212 patients. The multivariate logistic regression analysis showed that the high-density lipoprotein cholesterol (HDL-C) concentration and a complete anterior half of the circle of Willis were independent protective factors for good collateral circulation, whereas elevated lipoprotein(a) [Lp(a)] and serum creatinine concentrations were independent risk factors for good collateral circulation. The area under the receiver operating characteristics curve (AUC) was 0.68 (95% confidence interval [CI], 0.61–0.76) for HDL-C and 0.69 (95% CI, 0.62–0.76) for Lp(a). A binary logistic regression model analysis of the joint factor of HDL-C and Lp(a) yielded an AUC of 0.77 (95% CI, 0.71–0.84). Conclusions In patients with severe unilateral ICA stenosis or occlusion, the combination of HDL-C and Lp(a) is a useful predictor of collateral circulation.

BACKGROUND: Most Chinese migrants have been faced with obstacles to getting access to local public health services. Young migrants among internal migrants make a major contribution to the economy. However, the establishment of their health records has been ignored. This research was aimed at exploring the status and associated factors of the establishment of health records among young Chinese migrants. METHODS: Data were obtained from the 2017 China Migrants Dynamic Survey (CMDS). Chi-square test and binary logistic regression were performed to investigate the associated factors of the establishment of health records among young Chinese migrants. RESULTS: Approximately 30.2% of young migrants had their health records established in inflow communities. Urban residence, medical insurance (insured), and lower average monthly household income were attributed to the establishment of more health records. Young migrants who were in northeast China and across provinces and immigrated for working or engaging in trade were less likely to have health records established. Young migrants who participated in social activities and public affairs activities and took type of people in touch as natives in the inflow area showed a higher possibility of establishing health records. Meanwhile, receiving health education and hearing about national basic public health services (BPHSs) were beneficial for establishing the health records of more young migrants. CONCLUSION This study showed that the health records of young migrants had a relatively low establishment rate. Sociodemographic and migration characteristics, health status, public health services, and social integration factors were all related to the health record establishment of young Chinese migrants.

BACKGROUND: Limited published research has examined the relationships of negative life events and coping styles with sleep quality in Chinese junior high school students. We aimed to investigate the prevalence of poor sleep quality and to clarify the role of coping styles between negative life events and sleep quality. METHODS: A cross-sectional study of 3081 students was conducted in Ganzhou City, Jiangxi Province, Southeastern China. Adolescent Self-Rating Life Events Checklist, Simplified Coping Style Questionnaire, and Pittsburg Sleep Quality Index were applied to assess negative life events, coping styles, and sleep quality, respectively. Descriptive analyses, independent-samples t tests, one-way analyses of variance, Pearson correlation analyses, and structural equation modeling (SEM) were applied to analyze the data. RESULTS: The prevalence of poor sleep quality was 26.7%. Negative life events (B = 0.038, P < 0.001) and negative coping style (B = 0.049, P < 0.001) demonstrated a positive association with poor sleep quality, while positive coping style indicated a negative association with poor sleep quality (B = -0.029, P < 0.001). Interactions of negative life events and coping styles with sleep quality were not found (all P > 0.05). The association between negative life events and sleep quality was mediated by negative coping styles. CONCLUSIONS Our results indicated that poor sleep quality was common in these Chinese adolescents. Negative life events and negative coping style were associated with an increased prevalence of poor sleep quality, while the positive coping style was related to a decreased prevalence of poor sleep quality. A negative coping style mediated the association between negative life events and sleep quality.

Objective:To systematically review the effect of Tongfu Xiefei method on prognosis and respiratory mechanics parameters in patients with acute respiratory distress syndrome (ARDS).Methods:The randomized controlled trials (RCT) of Tongfu Xiefei method for ARDS published on PubMed, Web of Science, Embase, CNKI and Wanfang database from January 1st 2001 to June 30th 2019 were searched. Conventional treatment for ARDS that included mechanical ventilation, prone ventilation, anti-infection, organ function maintenance and nutritional therapy were used in the control group. While the Tongfu Xiefei method was applied in the experimental group based on the conventional treatment. The main outcome was in-hospital mortality, and the secondary outcomes included mechanic ventilation time, length of intensive care unit (ICU) stay and respiratory mechanics parameters. Two researchers independently searched the literature, collected data and assessed the risk of bias. The bias risk assessment was completed by RevMan 5.3 software. The Meta-analysis was completed by R software. The potential publication bias of main outcome was evaluation.Results:A total of 27 RCTs were included. There were 1 763 patients, including 899 in the experimental group and 864 in the control group. Meta-analysis showed that, compared with the control group, the in-hospital mortality of the experimental group significantly decreased [relative risk ( RR) = 0.46, 95% confidence interval (95% CI) was 0.36 to 0.59, P < 0.000 1], the mechanic ventilation time and the length of ICU stay were significantly shortened [mechanical ventilation time: standard mean difference ( SMD) = -1.92, 95% CI was -2.56 to -1.29, P < 0.000 1; length of ICU stay: SMD = -1.84, 95% CI was -2.49 to -1.18, P < 0.000 1], oxygenation index was significantly improved ( SMD = 2.26, 95% CI was 1.56 to 2.96, P < 0.000 1), airway peak pressure, airway platform pressure, mean airway pressure and airway resistance significantly decreased (airway peak pressure: SMD = -1.26, 95% CI was -2.35 to -0.18, P = 0.021 8; airway platform pressure: SMD = -0.61, 95% CI was -1.08 to -0.14, P = 0.010 7; mean airway pressure: SMD = - 1.67, 95% CI was - 2.93 to -0.42, P = 0.009 1; airway resistance: SMD = -0.88, 95% CI was -1.09 to -0.67, P < 0.000 1), while lung compliance increased ( SMD = 1.57, 95% CI was 0.78 to 2.36, P < 0.000 1). The results of publication bias assessment showed that there was no potential publication bias ( P = 0.499). Conclusion:Tongfu Xiefei method is capable of reducing the in-hospital mortality, shortening the mechanical ventilation time and the length of ICU stay, and improving respiratory mechanics parameters for patients with ARDS.

Objective To study the time-toxicity and dose-toxicity relationship of hepatotoxicity induced by Paracetamol Tablets (PT),Compound Paracetamol and Amantadine Hydrochloride Tablets (CPAH),Compound Dextromethorphan Hydrobromide Tablets (CDH),and Chaiqin Qingning Capsules (CQC) with single dose in mice.Methods In the Time-Toxicity relationship study,Kunming mice were randomly divided into control,PT,CPAH,CDH,and CQC group,and mice of.each drug administration group were randomly divided into nine subgroups according to the time (1,2,4,8,12,24,48,72 and 96 h after administration) of blood collection.The acetaminophen contents in PT,CPAH,and CDH groups were 425.98 mg/kg,and the dose of CQC group was 3 680.50 mg/kg.In the Dosage-Time relationship study,mice were randomly divided into control,PT,CPAH,CDH,and CQC high,medium and low dose group.The acetaminophen contents of high,medium,and low dose were 266.24,425.98,and 681.57 mg/kg in PT,CPAH,and CDH group,and the dose of CQC group was 1437.70,2300.31,and 3680.50 mg/kg,10 mice in each group,sex in half.Blood was collected 12 h after administration.Animal behavior was observed every day,blood and organs were collected at the corresponding time points,serum alanine aminotransferase (ALT),aspartate aminotransferase (AST),and alkaline phosphatase (ALP) level were detected,and the organs index of spleen and thymus,liver were calculated.Results There were no significant changes of ALT,AST,ALP,and organs index after once ig administration of CQC at dosage of 1437.70 mg/kg to 3680.50 mg/kg in mice.The study on time-toxicity relationship indicated that,after once administration of PT,CPAH,and CDH at 425.98 mg/kg,mice showed toxic symptom such as hypokinesia,dry hair and so on,12 h was the most obvious,24 ～ 72 h disappeared.The level of ALT,AST,and ALP in serum increased and reached to the peak at 12 h and then restored near normality after 72,24,and 24 h in PT,CPAH,and CDH group.Their organ index of liver,spleen and thymus all had no significant changes.The study on the dosage-toxicity relationship indicated that,there were no significant changes of animal behavior,ALT,AST,ALP,and organs index after once ig administration of PT,CPAH,and CDH at 266.24 mg/kg.Obvious liver injury can be induced by the three drugs with dosage of 425.98 to 681.57 mg/kg and the level of ALT,AST,and ALP increased significantly with the increase of dosage.Their liver index increased significantly with dosage of 681.57 mg/kg,but the organs index of spleen,thymus had no significant changes.Conclusion There was no hepatotoxicity after once ig administration of CQC with dosage of 3680.50 mg/kg in mice.Mice were once ig administration ofPT,CPAH,and CDH with a large dose,may induce acute liver injury and show obvious time-toxicity and dose-toxicity relationships.

Objective To study the dose-time-toxicity relationship of hepatotoxicity in mice with multiple administration of Paracetamol Tablets (PT),Compound Paracetamol and Amantadine Hydrochloride Tablets (CPAH),Compound Dextromethorphan Hydrobromide Tablets (CDH),and Chaiqin Qingning capsules (CQC).Methods Mice were randomly divided into control,PT,CPAH,CDH,and CQC high,medium,and low dose groups.The acetaminophen contents of high,medium,and low doses were 266.24,425.98,and 681.57 mg/kg in PT,CPAH,and CDH groups,and the doses of CQC group were 1437.70,2300.31,and 3 680.50 mg/kg,ig administration,once daily for 5 d.General state and toxicity of mice were observed.The changes of ALT,AST,AKP,TBIL,and ALB levels in serum and organ indexes of liver,spleen,thymus,and kidney were tested on day 1,3,7,11,and 14 after multiple administration.Results CQC with the dosage range of 1 437.70-3 680.50 mg/kg to mice within 14 d,has not yet induced the increase of AST,ALT,AKP,TBIL,and ALB levels and changes of organ indexes of liver,thymus spleen,and kidney compared with normal control (P ＞ 0.05).PT,CPAH,and CDH with repeated dose of 425.98-681.57 mg/kg could induce significant increase of the levels ofALT,AST,AKP,and TBIL which reached the peak on day 1 (P ＜ 0.05),and then gradually decreased on day 3-14.The level of ALB significant decreased on day 1-11 (P ＜ 0.05),and then gradually recovered on day 11-14.The liver index significant increased on day 1-3 (P ＜ 0.05),and recovered on day 7-14.Conclusion Multiple administration of CQC could not induce liver injury in mice within 14 d,while multiple administration ofPT,CPAH,and CDH could induce hepatotocixity in mice with a certain dose,and show an obvious dose-time-toxicity relationship.
