BackgroundWomen may develop severe symptoms of stress disorder following childbirth， which may be exposed to a risk of developing mental health problems， and even lead to the recurrence of the illness in female patients with schizophrenia， while comparatively limited research has been undertaken concerning the clinical characteristics and treatment of puerperal schizophrenia in China.ObjectiveTo explore the clinical characteristics of puerperal schizophrenia， so as to provide references for the clinical treatment.MethodsA total of 24 patients with puerperal schizophrenia who were hospitalized in the female ward of adult psychiatry department of the Affiliated Brain Hospital of Guangzhou Medical University from 2012 to 2020 and met the Diagnostic and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） diagnostic criteria for schizophrenia were included as puerperal group. Another 48 non-puerperal women with schizophrenia were concurrently enrolled as control group. Then the basic data， scores on Positive and Negative Symptom Scale （PANSS） and the discharge medication were recorded.ResultsThe percentages of newly onset and positive family history of psychosis in puerperal group were larger than those in control group， with statistical significance （χ2=9.321， 5.240， P

Internationalization and localization are important issues in the development of contemporary Chinese geography. China's local geographical knowledge research has become a force that cannot be ignored in the world's geographical knowledge system. This paper hopes to reveal the heterogeneity, complexity and diversity of the development of geography in the three countries by comparing the development characteristics of geography in China, Britain and the United States. By the knowledge mapping tool CiteSpace, this paper analyzes the literature of Journal of Geographical Sciences, Transactions of the Institute of British Geographers and Annals of the Association of American Geographers from 2010 to 2020, revealing the knowledge evolution, historical hot spots and thematic context of geography in the three countries in recent years. The findings are as follows: 1) American geography pays equal attention to both nature and humanity. In recent years, the comprehensive geographical research on the elements of "nature-environment-humanity-society" has been more active. It shows that American geography circle pays attention to the human-land contradiction and big politics of the world or other countries and regions on a large scale, as well as the human-land relationship and daily politics at the meso and micro scales. It pays attention to a wide range of topics, which are close to the hot spots and needs of American social development. 2) British geography is more "focused" on the study of human geography. In particular, the development of sociocultural geography is very characteristic, and the tradition of political geography is still distinct. There are common issues with the development of American geography, such as climate change, ethnic minorities and segregation. In addition, British geography has paid more and more attention to the research on the relationship between man and nature this year, and has gradually formed the voice of integrating natural and human geography research. 3) Chinese geography focuses on physical geography and regional research, which is different from the trend of American geography and British geography towards the research paradigm of "nature and human" integration. Human geography and geographic information science show rising trends, and the research area is mainly within China. Summarizing the development of geography research in the three countries is conducive to providing reference for the future research direction of Chinese geography and promoting the dialogue between China and world geography. Chinese geography needs to grasp the major demand traction of China's era change, deepen and strengthen the research of Chinese geography in theory and practice, and realize the diversified development of various branches and the transformation and integration of research paradigms.

ObjectiveTo explore the component factors of anhedonia in first-episode schizophrenia patients and the relationship with clinical symptoms， cognitive and social functioning.MethodsA total of 31 patients with first-episode schizophrenia who met the diagnostic criteria of the International Classification of Diseases， tenth edition （ICD-10） and another 33 healthy controls were enrolled. Then， the anhedonia level， mental symptoms， cognitive and social functioning were assessed using Temporal Experience of Pleasure Scale （TEPS）， Positive and Negative Syndrome Scale （PANSS）， Repeatable Battery for the Assessment of Neuropsychological Status （RBANS） and Personal and Social Performance Scale （PSP）. Thereafter， Pearson correlation was used to discuss the correlation of anhedonia level with clinical symptoms， cognitive and social functioning.ResultsThe consummatory anhedonia score in TEPS of first-episode schizophrenia patients was lower than that of healthy controls， with statistical difference ［（27.71±5.48） vs. （31.58±5.92）， t=2.705， P=0.009］. Correlation analysis showed that consummatory anhedonia had no correlation with PANSS， RBANS and PSP scores in first-episode schizophrenia patients（P>0.05）.ConclusionFirst-episode schizophrenia patients have consummatory anhedonia， and the consummatory anhedonia may be independent of clinical symptoms， cognitive and social functioning.

Research on the lithospheric elastic thickness (Te) of lunar mascon basins can provide a deeper understanding of heterogeneous thermal activity. In this study, we focused on four basins (Moscoviense, Freundlich‐Sharonov, Hertzsprung, and Apollo) located on the far side of the Moon. These basins exhibit a significant variation in admittance and correlation spectra, making it challenging to develop precise fitted models. Based on the global lunar crustal thickness model and mare basalt thickness, we developed a mantle and mare basalt load model to estimate the Te. This small Te (10.1 km) suggests a double impact process or extreme thermal activity caused by volcanism during the formation of the Moscoviense. For the typical highland basins, that is, Freundlich‐Sharonov and Hertzsprung, the Te (∼20 km) corresponds to a minimum heat flux of 34 mW m−2. Considering the additional energy introduced by the impact, this heat flux can be considered as the upper limit for the heat flux of the highland itself during the formation of a mascon basin. For the Apollo basin within the South Pole‐Aitken (SPA) terrane, the Te is 30.7 km. The crust beneath the SPA region is thinned, allowing a greater contribution of stiffer mantle material to the lithosphere, perhaps explaining the higher effective Te. Furthermore, the disparity between the highland and SPA terranes can give rise to their distinct basin formation processes. Impact basins formed within the SPA terrane may have experienced a faster cooling process compared to those formed on the highland terrane following the impact event, leading to a higher Te. Plain Language Summary: The study of impact basins on the far side of the moon not only provides valuable insights into the strength of the early growth stage of the lithosphere but also gives a glimpse into the different thermal evolution histories of the lunar highland and the South Pole‐Aitken (SPA). In this study, we construct a lithospheric load model by incorporating the contributions of both mantle plug and mare basalts. The proposed model is applied to the four typical mascon (mass concentration) basins. The smaller elastic thickness of the Moscoviense basin may be attributed to a double shock process or intense thermal activity. The Nectarian Hertzsprung basin is younger than the Pre‐Nectarian Freundlich‐Sharonov basin on the highland. However, the two basins exhibit similar elastic thickness, indicating that the latter have either a slow cooling rate or rapid completion of the super‐isostatic adjustment process. The difference in elastic thickness between the Apollo and the highland basins such as the Freundlich‐Sharonov and Hertzsprung basins could be attributed to variations in geological composition, density, and porosity between the SPA and the highland terrane. Key Points: The smaller Te of the Moscoviense basin suggests that it might have undergone either a double impact process or intense volcanic activityThe elastic thickness of the typical highland mascon basins is about 20 km, corresponding to a minimum heat flux of 34 mW m−2The mascon basins formed in the SPA terrane and the typical highland terrane may experience distinct post‐impact cooling processes [ABSTRACT FROM AUTHOR]
