Previous studies suggest that the senescence and death of the replaceable bud of the Chinese chestnut cultivar (cv.) “Tima Zhenzhu” involves programmed cell death (PCD). However, the molecular network regulating replaceable bud PCD is poorly characterized. Here, we performed transcriptomic profiling on the chestnut cv. “Tima Zhenzhu” replaceable bud before (S20), during (S25), and after (S30) PCD to unravel the molecular mechanism underlying the PCD process. A total of 5,779, 9,867, and 2,674 differentially expressed genes (DEGs) were discovered upon comparison of S20 vs S25, S20 vs S30, and S25 vs S30, respectively. Approximately 6,137 DEGs common to at least two comparisons were selected for gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses to interrogate the main corresponding biological functions and pathways. GO analysis showed that these common DEGs could be divided into three functional categories, including 15 cellular components, 14 molecular functions, and 19 biological processes. KEGG analysis found that “plant hormone signal transduction” included 93 DEGs. Overall, 441 DEGs were identified as related to the process of PCD. Most of these were found to be genes associated with ethylene signaling, as well as the initiation and execution of various PCD processes.

Cold stress is a serious threat to global crop production and food security, but plant cold resistance is accompanied by reductions in growth and yield. In this study, we determined that the novel gene BcGSTF10 in non-heading Chinese cabbage [NHCC; Brassica campestris (syn. Brassica rapa) ssp. chinensis ] is implicated in resistance to cold stress. Biochemical and genetic analyses demonstrated that BcGSTF10 interacts with BcICE1 to induce C-REPEAT BINDING FACTOR (CBF) genes that enhance freezing tolerance in NHCC and in Arabidopsis. However, BcCBF2 represses BcGSTF10 and the latter promotes growth in NHCC and Arabidopsis. This dual function of BcGSTF10 indicates its pivotal role in balancing cold stress and growth, and this important understanding has the potential to inform the future development of strategies to breed crops that are both climate-resilient and high-yielding.

Anxiety and depressive symptoms are prevalent in women with polycystic ovary syndrome (PCOS), and there is a great need for culturally relevant interventions to improve anxiety and depressive symptoms in women with PCOS. The current study aimed to analyze the factors influencing body-image satisfaction, anxiety, and depressive symptoms in Chinese women with PCOS. It also aimed to clarify the association between body-image satisfaction and anxiety and depressive symptoms in women with PCOS, and whether this association was mediated by cognitive reappraisal and expressive suppression. A total of 477 women with PCOS were recruited from the Department of Gynecology and Reproductive Medicine Center of one university-affiliated tertiary hospital in China. They completed the Generalized Anxiety Disorder-7 scale, the Patient Health Questionnaire-9, the Body Image States Scale, and the Emotion Regulation Questionnaire. The study found body-image satisfaction showed significant associations with anxiety and depressive symptoms. This association was mediated by cognitive reappraisal and expressive suppression. The findings of this study offer new insights into the relationship between body image and anxiety and depressive symptoms in women with PCOS. They also emphasize the potential value of promoting body-image satisfaction and enhancing cognitive reappraisal abilities to improve the mental health of women with PCOS. [ABSTRACT FROM AUTHOR]

Life and civilization in arid regions depend on the availability of freshwater. Arid alpine river basins, where hydrological processes are highly sensitive to rapid warming, act as vital water towers for lowland oases. However, scientific understanding of precipitation variability and related cryosphere–hydrology processes is extremely limited because of the scarcity of in situ observations. The upper Danghe River basin (UDB; ∼14,000 km2) is an arid and westerly dominated basin on the northeastern Tibetan Plateau and is the water source for the Dunhuang Oasis in China. We have established a comprehensive cryosphere–hydrometeorology observation network in the basin since 2014. At present, the network consists of 21 automatic rain gauges, 22 soil freeze–thaw monitoring stations, 4 automatic weather stations (AWS), and a 50-m gradient meteorological tower with an eddy covariance system. In particular, the 18 sites, located in remote areas without public networks, are equipped with new-generation BeiDou-3 communication terminals that enable the observations to be easily, safely, and reliably read and quality controlled in near–real time from offices in the city or at home. This integrated observation network over the UDB that facilitates the monitoring of cryosphere–hydrology processes, land–atmosphere interactions, and local weather processes. In addition, the observations are helpful for the objective evaluation, and continual improvement, of hydrological models, satellite-retrieval products, and reanalysis datasets. Finally, the network is expected to promote a better understanding of the status and role of water towers in arid zones and to provide basic data support for the sustainable development of the Dunhuang Oasis and the Belt and Road.

This cross-sectional study aimed to identify latent mental health subgroups of reproductive-aged women with polycystic ovary syndrome (PCOS) and examine differences in emotion regulation and social support. A total of 477 samples (age = 27.22 ± 5.37) diagnosed with PCOS were included in this study, all of whom were of the same ethnicity. Latent profile analysis (LPA) was conducted in Mplus version 8.3 to identify mental health latent profiles in women with PCOS based on the dual-factor approach. The current study identified three distinct mental health profiles within women with PCOS: High-Symptom and High-Well-being Profile, Low-Symptom and High-Well-being Profile, and High-Symptom and Low-Well-being Profile, with group proportions of 52.3%, 35.7%, and 11.1%, respectively. This study revealed that cognitive reappraisal and social support are important protective factors for the mental health of women with PCOS, whereas expressive suppression is a negative factor for their mental health.

Cognitive behavioural therapy (CBT) has been used for women with infertility. However, the efficacy of CBT among the infertile female population remains inconclusive. We performed a systematic literature search using the Cochrane Library, MEDLINE (OVID), EMBASE (OVID), CINAHL, PsycINFO (OVID), Web of Science, and ProQuest databases from the inception to May 2022. The Cochrane risk of bias tool for randomized trials was used to assess the methodological quality of the included studies. Revman 5.4 was conducted for statistical analysis, and meta‐analyses were performed to calculate the pooled effects of CBT. Sixteen articles were finally included in the meta‐analysis. The results of the meta‐analysis revealed large, significant effects of cognitive‐behavioural interventions that can effectively reduce depression, anxiety symptoms, psychological distress, perceived stress, infertility‐specific stress, and improve the quality of life in women with infertility. However, the pooled MD using a fixed‐effects model was 0.25, 95% CI [−0.33, 0.84], P = 0.40, and no significant differences in BMI were observed among those who received CBT therapy compared with those who did not. CBT effectively alleviates depression, anxiety, psychological distress, and infertility‐specific stress levels and improves the quality of life among women with infertility. Future studies should explore the sustainability and long‐term effect of cognitive‐behavioural interventions in women with infertility. [ABSTRACT FROM AUTHOR]

Aim: The current systematic review aimed to present the pooled estimated prevalence and risk factors of PPD. Background: Postpartum depression seriously affects the physical and mental health of the mother and child. However, high‐quality meta‐analysis is limited, which restricts the screening and intervention of postpartum depression. Design: A systematic review and meta‐analysis. Methods: Cochrane Library, PubMed, Embase and Web of Science were searched for cohort and case‐control studies investigating the prevalence and risk factors of postpartum depression from inception to December 31st, 2020. Meta‐analyses were performed to identify postpartum depression prevalence and risk factors using a random‐effects model. Results: Of the 33 citations evaluated, 27 reported the prevalence of postpartum depression in 33 separate study populations containing 133,313. subjects. Pooled prevalence in all studies was 14.0% (95%CI, 12.0%–15.0%). The prevalence varied according to country (from 5.0% to 26.32%) and developing countries, especially China, have a high prevalence of postpartum depression. The following risk factors were associated with postpartum depression: gestational diabetes mellitus(OR = 2.71, 95%CI 1.78–4.14, I2 = 0.0%), depression during pregnancy(OR = 2.40, 95%CI 1.96–2.93, I2 = 96.7%), pregnant women give birth to boys(OR = 1.62; 95%CI 1.28–2.05; I2 = 0.0%), history of depression during pregnancy(OR = 4.82, 95%CI 1.32–17.54, I2 = 74.9%), history of depression(OR = 3.09, 95%CI 1.62–5.93, I2 = 86.5%) and epidural anaesthesia during delivery(OR =.81, 95%CI.13–4.87, I2 = 90.1%). Conclusions: The prevalence of postpartum depression seems to be high, especially in developing countries. Gestational diabetes mellitus, depression during pregnancy, pregnant women give birth to boys, history of depression during pregnancy, history of depression, epidural anaesthesia during delivery were identified as risk factors for postpartum depression. Understanding the risk factors of PPD can provide the healthcare personnel with the theoretical basis for the patients' management and treatment. Implications for practice: This systematic review and meta‐analysis identified six significant risk factors for PPD, which provides nurses with a theoretical basis for managing and treating women with PPD to effectively improve the screening rate, intervention rate and referral rate of women with PPD.
