The main pathological features of Parkinson disease(PD)include accumulation of α-synuclein and loss of dopaminergic neurons.PET imaging can be used to diagnose and monitor PD and explore its neural mechanisms through specific targeted imaging agents.The research progresses of PD related PET imaging agents were reviewed in this article.

Objective:To explore the longitudinal relationship between adolescents' future self-continuity and depression, providing insights into their future development.Methods:A total of 419 adolescents from a school in Shandong Province were selected, and two followed-up surveys were conducted at 6-month intervals in April (T1) and October (T2) of 2023 using the future self-continuity questionnaire and Beck depression inventory-Ⅱ. Cross-lagged analysis was performed using Mplus 8.0.Results:The scores of future self-continuity were 36.01±8.69 at baseline (T1) and 35.89±9.92 after six months (T2), while the scores of depression were 2.00(0, 14.00) and 1.00(0, 9.00), respectively. There was a negative correlation between future self-continuity and depression at both time points (T1: r=-0.195, T2: r=-0.239, both P<0.01). Adolescents' future self-continuity could predict depression six months later ( β=-0.098, P<0.01), and depression also could predict the level of future self-continuity six months later ( β=-0.114, P<0.01). Conclusion:There is an interactively influence effect between adolescents' future self-continuity and depression.While enhancing adolescents' future self-continuity level to alleviate depression, attention should also be paid attention to the impact of depression on their future self-continuity, which can help adolescents overcome the interference of depressive emotions and grow into a better future self.

Rubus corchorifolius(Shanmei or mountain berry,2n=14)is widely distributed in China,and its fruits possess high nutritional and medicinal values.Here,we reported a high-quality chromosome-scale genome assembly of Shanmei,with contig size of 215.69 Mb and 26,696 genes.Genome comparison among Rosaceae species showed that Shanmei and Fupenzi(Rubus chingii Hu)were most closely related,followed by blackberry(Rubus occidentalis),and that environmental adaptation-related genes were expanded in the Shanmei genome.Further resequenc-ing of 101 samples of Shanmei collected from four regions in the provinces of Yunnan,Hunan,Jiangxi,and Sichuan in China revealed that among these samples,the Hunan population of Shanmei possessed the highest diversity and represented the more ancestral population.Moreover,the Yunnan population underwent strong selection based on the nucleotide diversity,linkage dise-quilibrium,and historical effective population size analyses.Furthermore,genes from candidate genomic regions that showed strong divergence were significantly enriched in the flavonoid biosyn-thesis and plant hormone signal transduction pathways,indicating the genetic basis of adaptation of Shanmei to the local environment.The high-quality assembled genome and the variome dataset of Shanmei provide valuable resources for breeding applications and for elucidating the genome evo-lution and ecological adaptation of Rubus species.

Objective To explore the irradiation-increased krebs yon den lungen-6 (KL-6) in predicting radiation pneumonitis (RP) after lung cancer radiotherapy.Methods A total of 87 hospitalized patients with Ⅰ-Ⅲ stages of lung cancer from June 2015 to December 2015 were followed up,and their clinicopathological data and serum KL-6,transforming growth factor-beta 1 (TGF-β1)and lactate dehydrogenase (LDH)before and 3 months after radiotherapy were analyzed to determine their role in predicting RP induction in lung cancer.Results Among the 87 lung cancer patients based on clinical symptoms and chest CT,13 patients were diagnosed with ≥2 grape RP.Before radiotherapy,the average levels of serum KL-6 were (247 ± 105.44) U/ml in 13 patients with ≥ 2 grape RP and (209 ± 71.09) U/ml in 74 cases 0/1 grape RP,respectively.Within 3 months after radiotherapy,the highest level of KL-6 approached to (456 ± 202.84) and (222 ± 80.42) U/ml with increase ratios of 2.01 ± 1.04 and 1.13 ± 0.60 in the ≥2 grape RP and 0/1 grape RP,respectively.The difference of KL-6 levels between these two groups was significant (t =2.901,P ＜ 0.005).While the levels of TGF-β1 and LDH did not change.ROC analysis showed that the sensitivity of the ratio of serum KL-6 increased after radiotherapy was 0.923％ and the specificity was 0.851％ at 1.435 as the critical value.Furthermore,the multi-variate logistic regression analysis showed that the ratio of KL-6 increased as an independent risk factor of ≥ 2 grade RP in lung cancer (OR =12.886,95％ CI =3.372-49.247,P =0.002).Conclusions The increased ratio (≥ 1.435) of KL-6 is closely correlated with the ≥2 grape RP in lung cancer,which could be used as a predictor of ≥2 grape RP in lung cancer.

Objective To explore the establishment and effectiveness of school-based training bases.Methods Two hundred forty-six nursing students having finished theoretical learning and possessing into clinical practice were divided into the control group(n=121)and the observation group(n=125).The control group received the conventional training in out-school training bases and the observation group in the school-based training bases.The two groups were compared in terms of creative thinking and the performances of nursing theory,manipulations and assessed by their teachers.Result The scores on creative thinking and the performances in nursing theory and manipulation in the observation group were both significantly higher than the control group(P<0.05)and the assessment by teachers in the observation group was better than the control group.Conclusion The school-based training base used for nursing teaching can not only improve the nursing theory and manipulation of nursing students but also improve the creative thinking.
