BackgroundPreventing and intervening in adolescent gaming disorder is of significant practical importance. Gaming motivation is strongly linked to gaming addiction and serves a key function in comprehending and addressing addictive gaming behaviors. However， the relationship between components of gaming motivation and symptoms of gaming disorder remains unclear. ObjectiveTo explore the relationship between components of gaming motivation and symptoms of gaming disorder among adolescents， so as to provide references for the prevention and intervention of gaming disorder in this population. MethodsFrom January to February 2024， a cluster sampling method was employed to select 1 414 adolescents from four middle schools in Sichuan Province and Chongqing Municipality as participants in the study. Online Game Motivation Scale （OGMS） and Gaming Disorder Scale for Adolescents （GADIS-A） were administered. Network analysis methods were utilized to investigate the relationships between components of gaming motivation and symptoms of gaming disorder. ResultsThe network edge weights revealed that achievement motivation was positively correlated with impaired game control ability， continued gaming despite negative consequences and the frequency of symptom occurrence （r=0.115， 0.050， 0.076， P<0.05）. Social motivation was negatively correlated with negative consequences （r=-0.054， P<0.05），while immersion motivation was positively correlated with continued gaming despite negative consequences （r=0.032， P<0.05）. Achievement motivation exhibited the highest strength centrality （1.157） among the three components of gaming motivation. ConclusionThe connections between components of gaming motivation and symptoms of gaming disorder exhibit distinct patterns， with each motivational component influencing gaming disorder through specific symptom pathway. Among these components， achievement motivation plays the most critical role in the interplay between gaming motivation and symptoms of gaming disorder. ［Funded by Chongqing Science and Health Joint Medical Science and Technology Innovation Projects General Projects （number， 2023MSXM133）］

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective:To explore the predictive value of miR-21 combined with high mobility group box-1 protein (HMGB1) for postoperative prognosis in patients with hypertensive intracerebral hemorrhage (HICH).Methods:A total of 137 HICH patients (HICH group) admitted to the Central Hospital of Yongzhou from March 2021 to March 2023 were retrospectively selected, and 60 healthy subjects undergoing physical examination in the same hospital during the same period were enrolled as the control group. Serum miR-21 and HMGB1 levels were compared between the two groups, and differences in serum miR-21 and HMGB1 levels among HICH patients with different disease severities and prognoses were analyzed. Univariate and multivariate logistic regression analyses were used to screen influencing factors for postoperative prognosis in HICH patients, and receiver operating characteristic (ROC) curve was applied to evaluate the predictive value of miR-21 combined with HMGB1 for postoperative prognosis.Results:The relative expression level of serum miR-21 on postoperative day 1 in the HICH group was significantly lower than that in the control group ( P<0.05), while the HMGB1 level was significantly higher ( P<0.05). With the aggravation of HICH severity, the relative expression of serum miR-21 significantly decreased (all P<0.05), while the HMGB1 level significantly increased (all P<0.05). The relative expression of serum miR-21 in the good prognosis group was significantly higher than that in the poor prognosis group ( P<0.05), while the HMGB1 level was significantly lower ( P<0.05). Univariate and multivariate logistic regression analyses showed that miR-21, HMGB1, preoperative Glasgow Coma Scale (GCS) score, and preoperative hematoma volume were influencing factors for postoperative prognosis in HICH patients (all P<0.05). ROC curve showed that the areas under the curve (AUC) of miR-21 and HMGB1 for predicting poor postoperative prognosis in HICH patients were 0.925 and 0.913, respectively, while the AUC of miR-21 combined with HMGB1 was 0.950. Conclusions:Peripheral blood miR-21 is significantly decreased and HMGB1 level is significantly increased in HICH patients. miR-21 combined with HMGB1 has a good predictive value for poor postoperative prognosis in patients with hypertensive intracerebral hemorrhage.

The policy of long-term prescription for chronic diseases in China is gradually being improved and implemented， and external long-term prescription dispensing is being encouraged. The long-term prescription policy runs through the links of drug supply， equipment， use and policy， involving government departments such as medical security and health， as well as stakeholders such as patients， medical institutions and designated detail pharmacies. There are still some problems in the external dispensing of long-term prescriptions， such as the disunity of drug catalogue and the need for coordination among regulatory parties in the policy link； the need to improve the participation enthusiasm and service ability in the equipment link； the increased difficulty of prescription management， the need to improve the circulation platform in the use link. The promotion of external long-term prescription policy requires health insurance， medical service， and the medicine industry co-development， multi-party participation， and policy coordination. Among them， the “dual channel” policy， the policy of centralized medicine procurement， and the pharmacy included in outpatient overall management policy have all played a positive role in promoting the implementation of external long-term prescription dispensing for chronic diseases. It is necessary to improve supporting policies and implement regulatory responsibilities in the policy link， promote drug classification and service capabilities in the equipment link， improve the electronic prescription circulation platform， and strengthen prescription management in use link， so as to promote the implementation of external long-term prescription dispensing.
