BackgroundIn China， the structure shift from just one-child family to both one-child and more-than-one-child families is happening. Exploring how the sibling relationships effect between adolescent personality impulsivity and aggressivity is of great significance for promoting adolescent mental health as well as maintaining social harmony and stability. ObjectiveTo investigate the effecting path of sibling relationships between personality impulsivity and aggressivity in adolescents， so as to provide references for the prevention of violent and aggressive behavior in adolescents. MethodsFrom February to April， 2023， a total of 1 200 students with sibling relationships from 12 primary and secondary schools in a county of Sichuan province were included by random sampling. Barratt Impulsivity Scale （BIS-11）， Chinese Version of Buss & Perry Aggression Questionnaire （AQ-CV）， and Sibling Relationship Questionnaire （SRQ） were used for cross-sectional investigation. Pearson Correlation Analysis was used to analyze the correlation between the scores of these scales. Bootstrap method was used to test the effecting path of sibling relationships between personality impulsivity and aggressivity. ResultsThe total score of BIS-11 was positively correlated with that of AQ-CV as well as the scores of conflict and competition dimensions in SRQ （r=0.485、0.276、0.280，P<0.01）， while negatively correlated with the score of warmth/intimacy dimension in SRQ （r=-0.383， P<0.01）. The total score of AQ-CV was positively correlated with the scores of conflict and competition dimensions in SRQ （r=0.387， 0.340， P<0.01）， while negatively correlated with the score of warmth/intimacy dimension in SRQ （r=-0.304， P<0.01）. Within SRQ， negative correlations could be observed between the score of warmth/intimacy and scores of conflict and competition （r=-0.307， -0.375， P<0.01）， whereas positive correlation could be observed between the score of conflict and that of competition （r=0.267， P<0.01）. The total effect of personality impulsivity level on aggressivity level in adolescent was 0.480 （P<0.01）. Sibling relationships played a mediating role between personality impulsivity and aggressivity in adolescents. Meanwhile， the indirect effect values of warmth/intimacy， conflict and competition were 0.054， 0.075 and 0.062， with the effect values accounting for 11.21%， 15.70% and 12.93%， respectively. ConclusionThe personality impulsivity of adolescents can directly affect their aggressivity， and sibling relationships may act as an important channel connecting personality impulsivity and aggressivity. ［Funded by 2023 Project of the Psychology and Behavioral Science Research Center of the Deyang Federation of Social Sciences （number， XLYXW2023305）］

Objective:To evaluate the practical value of ultrasound, ultrasound new technologies (ultrasound elastography, contrast enhanced ultrasound) and computed tomography (CT) examination alone or the combination of both of the four in the clinical diagnosis of lymph node metastasis of thyroid cancer by meta-analysis system.Methods:This study screened relevant literature on ultrasound, new ultrasound technologies, and CT in the diagnosis of lymph node metastasis of thyroid cancer by searching Chinese and English databases from January 2006 to August 2023. Two scholars independently assessed the quality of the literatures and scored them using the QUADAS scale. Then, the diagnostic ratio of single and combined examinations was analyzed by Meta-Disc software, and the heterogeneity test and meta-analysis were performed to calculate the sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic ratio, accuracy, and area under curve (AUC). Finally, the diagnostic efficacies of different diagnostic techniques and their combination in identifying lymph node metastasis of thyroid cancer were assessed by calculating OR and P values by two-by-two comparisons. Results:Sixty-nine diagnostic studies totaling 30, 666 lesions were finally included. The meta-analysis study showed that contrast enhanced ultrasound had the highest sensitivity[0.83(0.77-0.87)], ultrasound specificity was the highest [0.84(0.79-0.88)], the highest AUC was for contrast enhanced ultrasound (0.90), and contrast enhanced ultrasound and ultrasound elastography had high accuracies (0.81, 0.80, respectively) both of them were higher than those of ultrasound (0.77) and CT (0.69). Contrast enhanced ultrasound and ultrasound elastography were both more sensitive than CT, with statistically significant differences between them ( P<0.01); contrast enhanced ultrasound + ultrasound elastography had the highest accuracy, while ultrasound + contrast enhanced ultrasound and contrast enhanced ultrasound + ultrasound elastography were both more sensitive, with no statistically significant differences between them ( P>0.05), but the latter had the highest specificity [0.90(0.88-0.92)], which were statistically significantly different from each other ( P<0.05), ultrasound+ contrast enhanced ultrasound and contrast enhanced ultrasound+ ultrasound elastography had higher sensitivities than ultrasound+ CT, which were statistically different from each other ( P<0.05), and ultrasound+ CT had the lowest specificity [0.76(0.70-0.81)]. Conclusions:The diagnostic efficacy of thyroid cancer lymph node metastasis is highest with contrast enhanced ultrasound. The new ultrasound technique for diagnosing thyroid cancer lymph node metastasis has a higher diagnostic value than CT, and it can be used as a complementary examination to conventional ultrasound.When the two techniques are used in combination, contrast enhanced ultrasound + ultrasound elastography has the highest accuracy, contrast enhanced ultrasound + ultrasound elastography and ultrasound + contrast enhanced ultrasound both have high sensitivity and specificity, and the diagnostic performance of both is higher than that of ultrasound + ultrasound elastography and ultrasound + CT, and in actual clinical practice when ultrasound elastography combined with contrast enhanced ultrasound is limited in the examination, ultrasound combined with contrast enhanced ultrasound can effectively serve as an alternative means to provide a good diagnostic support.

In recent years, there has been an increasing emphasis on exploring innovative drug delivery approaches due to the limitations of conventional therapeutic strategies, such as inadequate drug targeting, insufficient therapeutic efficacy, and significant adverse effects. Nanomedicines have emerged as a promising solution with notable advantages, including extended drug circulation, targeted delivery, and improved bioavailability, potentially enhancing the clinical treatment of various diseases. Natural products/materials-derived nanomedicines, characterized by their natural therapeutic efficacy, superior biocompatibility, and safety profile, play a crucial role in nanomedicine-based treatments. This review provides a comprehensive overview of currently approved natural products-derived nanomedicines, emphasizing the essential properties of natural products-derived drug carriers, their applications in clinical diagnosis and treatment, and the current therapeutic potential and challenges. The aim is to offer guidance for the application and further development of these innovative therapeutic approaches.

ObjectiveTo investigate the mediating role of loneliness and social anxiety in the relationship between basic psychological needs satisfaction and smartphone addiction among high school students， and to provide references for the intervention to smartphone addiction for high school students. MethodsIn April 2022， a total of 14 666 high school students from 5 middle schools in a county of Sichuan Province were included by random sampling method. Basic Psychological Needs Scales （BPNS）， the UCLA Loneliness Scale-3 edition （UCLA-3）， Interaction Anxiousness Scale （IAS） and the Mobile Phone Addiction Index （MPAI） were used for cross-sectional investigation. Bootstrap method was used to analyze the mediating role of loneliness and social anxiety in the relationship between the basic psychological needs satisfaction and smartphone addiction. Results① In this study， 14 036 valid questionnaires were returned， and 1 752 （12.48%， 95% CI： 0.114~0.136） high school students were found to be addicted to smartphone phone. The BPNS score was negatively correlated with UCLA-3， IAS and MPAI scores （r=-0.771， -0.486， -0.417， P<0.01）. And MPAI score was positively correlated with IAS and UCLA-3 scores （r=0.403， 0.424， P<0.01）. IAS score was positively correlated with UCLA-3 score （r=0.458， P<0.01）. ②The degree of basic psychological needs satisfaction in high school students can directly negatively predict smartphone addiction （β=-0.383， P<0.05）， and can also indirectly affect smartphone addiction through loneliness and social anxiety （β=-0.130， P<0.05）. ③Loneliness （indirect effect value was -0.145） and social anxiety （indirect effect value was -0.074） partially mediate between the basic psychological needs satisfaction and smartphone addiction. Loneliness-social anxiety also has significant chain mediating effect （indirect effect value was -0.034）， which accounted for 8.88%. ConclusionThe basic psychological needs satisfaction can not only directly affect the occurrence of smartphone addiction， but also indirectly affect the occurrence of smartphone addiction through the chain mediation of loneliness and social anxiety.

METHODS: The hospitalization data and medical records of patients with gout between January, 2012 and June, 2019 were retrieved from the database of Anhui Provincial Hospital of Traditional Chinese Medicine, and the echocardiographic parameters and clinical laboratory test results of the inflammatory, immunological and metabolic indicators were analyzed. SPSS 22.0, SPSS Clementine 11.1 Aprior and other statistical software were used to determine the association rules and carry out correlation analysis, heat map analysis and multi-factor logistic regression analysis of the indicators. RESULTS: Heat map analysis showed that the expressions of EF and SV were the most significant, followed by AODd, LADs, LVDd and FS. Cluster analysis showed that AODd, EF, FS, LADs, LVDd, and SV were all in cluster 1, and IVSTd, LVPWTd, MPAD, Pmax, and RVDd were in cluster 2. Correlation analysis showed that in the 383 patients, EF was negatively correlated with LVDd ( < 0.05) and positively correlated with FS and SV ( < 0.05); AODd was positively correlated with IVSTd, LADs, LVDd, LVPWTd, RVDd, SV, and ESR ( < 0.05); FS was positively correlated with EF and SV ( < 0.05) and negatively correlated with LVDd ( < 0.05);IVSTd was positively correlated with AODd, LADs, LVPWTd, and complement C4 ( < 0.05); LADs were positively correlated with AODd, IVSTd, MPAD, RVDd, and SV ( < 0.05); LVDd was positively correlated with AODd, IVSTd ( < 0.05), and negatively correlated with LVDd and complement C3 ( < 0.05); MPAD and LADs, HDLC and TC were positively correlated ( < 0.05)and negatively correlated with Pmax ( < 0.05); Pmax was positively correlated with LVDd, RVDd and SV ( < 0.05)and negatively correlated with FS and MPAD ( < 0.05); RVDd was positively correlated with AODd, LADs, LVDd, Pmax, SV ( < 0.05); SV was positively correlated with AODd, EF, LADs, LVDd, Pmax, and RVDd ( < 0.05); complement C3 was positively correlated with complement C4 and CRP ( < 0.05), and negatively correlated with LVPWTd ( < 0.05); complement C4 was positively correlated with IVSTd, complement C3, CRP, and ESR ( < 0.05); CRP was positively correlated with complement C3, complement C4, IgA, IgG ( < 0.05), and negatively correlated with TC, HDLC, and TG ( < 0.05); TG was positively correlated with HDLC, IgM, and TC ( < 0.05), and negatively correlated with CRP ( < 0.05); HDLC was positively correlated with MPAD, HDLC and TC ( < 0.05) and negatively correlated with CRP ( < 0.05); IgA was positively correlated with CRP, IgG and IgM ( < 0.05); IgG was positively correlated with CRP, IgA and IgM ( < 0.05); IgM is positively correlated with TG, IgA, IgG, UA ( < 0.05) and negatively correlated with CRP ( < 0.05); UA was positively correlated with IgM ( < 0.05); ESR was positively correlated with AODd and complement C4 ( < 0.05); HCY was negatively correlated with RVDd ( < 0.05); TC was positively correlated with MPAD and TG ( < 0.05), and negatively correlated with CRP ( < 0.05). The increase of Pmax was significantly associated with the increase of LDL-C, UA, complement C4, TG, HCY, HDL-C, IgG, ESR, CRP, and complement C3; the increase of SV was associated with the elevations of UA, LDL-C, complement C4, HDL-C, CRP, IgG, HCY, TC, ESR, TG, and complement C3. Multivariate logistic regression analysis indicated that FS was positively correlated with LDL-C ( < 0.05), Pmax was negatively correlated with IgM ( < 0.05), and SV was negatively correlated with ESR ( < 0.05). CONCLUSIONS The changes of echocardiographic parameters in patients with gout are correlated with the increase in inflammation, immunity, and metabolic indexes. Patients with a history of smoking and drinking do not show obvious changes in cardiac function. The changes in metabolic indexes are risk factors for changes in echocardiographic parameters.

Objective To investigate the epidemic factors of schistosomiasis in wetlands in Sichuan Province, so as to provide scientific evidence for the prevention and control of schistosomiasis in wetlands. Methods The artificial and natural wetlands were selected from Sichuan Province, and the relevant data regarding wetlands were collected. Routine snail survey, investigation on human morbidity due to schistosomiasis, snail diffusion experiments, questionnaire survey, determination of water infectivity and retrospective survey were conducted. Results In Sichuan Province, the mean densities of living snails were 0.003 snails/0.1 m² and 2.033 snails/0.1 m² in the upper and lower reaches of the Meiwan Reservoir wetlands, 0.08 snails/0.1 m² in the Jinyan Lake of Guanghan City, 0.21 snails/0.1 m² in Muhe River of Guanghan City, and 0.02 snails/0.1 m² prior to the construction of Qiong-hai wetland park in Xichang City in 2015. Artificial simulation experiments showed that the largest distance of snail diffusion in water was 2 000 m. There were 8.80% (41/466) of subjects that lived neighboring wetlands, worked in wetlands and visited wet-lands having infested water contact behaviors. A total of 690 sentinel mice were assigned, and no Schistosoma japonicum infection was detected in the 677 mice dissected. Retrospective survey showed that the construction of the Meiwan Reservoir caused the spread of schistosomiasis in Dailing County, and snails were found in the ditches entering the Jinyan Lake and in Jinyan Lake areas 5 years following the construction of the Jinyan Lake in Guanghan City, with S. japonicum -infected snails detected in the ditches entering the Jinyan Lake. Conclusions O. hupensis snails are found in some wetlands in Sichuan Province. Protection of wetlands and snail control with environmental improvements are recommended for the prevention of snail importation in natural wetlands, while in artificial wetlands, thorough snail control is recommended during the construction of the wetlands because of the likelihood of snail importation via water systems. In addition, both natural and artificial wetlands require long-term systematic surveillance of schistosomiasis.
