Background: Regular participation in physical activity (PA) reduces all-cause mortality (ACM) in the general population. However, the effects of PA on depressed patients and potential gender-specific responses have not been fully elucidated. In this study, we aimed to investigate the role of PA on new-onset depression and ACM in Chinese adults aged 45 year and older, with particular emphasis on gender differences.

Depression is a common psychiatric disorder that belongs to the category of "Depression Syndrome" in traditional Chinese medicine (TCM), and its etiology and pathogenesis are complex and unclear. It is characterized by high prevalence, high disability rate, and high recurrence rate, which seriously affect human health, and its treatment has become a research hotspot worldwide. At present, the antidepressants commonly used in the clinic are mainly Western medicine (WM), but there are problems such as frequent side effects and poor efficacy.

Background: Previous observational epidemiological studies reported an association between cathepsins and cancer, however, a causal relationship is uncertain. This study evaluated the causal relationship between cathepsins and cancer using Mendelian randomization (MR) analysis.

Methods: We used publicly available genome-wide association study (GWAS) data for bidirectional MR analysis.

Article Synopsis
  • Polycystic ovary syndrome (PCOS) leads to reproductive issues and gut microbiota imbalances, with physical activity potentially helping to improve these conditions through mechanisms that remain unclear, particularly involving the myokine irisin.* -
  • In a study with mice, irisin was administered to a group with induced PCOS, revealing that it helped correct hormonal disorders, ovarian issues, and gut microbiota disturbances without affecting oocyte quality.* -
  • The findings indicate that irisin may benefit PCOS treatment by addressing gut microbiota dysbiosis and altering certain fecal metabolites linked to hormonal imbalances.*

Article Synopsis
  • - The study explores chronic dacryocystitis (CDC) and its link to various bacteria, suggesting that understanding the microflora can help in prevention and treatment strategies for the condition.
  • - Using 16S rRNA sequencing, researchers analyzed the bacterial flora in 78 patients, grouping them based on healthy vs. infected eye secretions.
  • - Findings showed that while overall bacterial diversity was similar among groups, specific bacterial compositions differed, indicating that changes in microbiota could guide antibiotic treatment for CDC.

Homeodomain (HD) proteins regulate embryogenesis in animals such as the fruit fly (Drosophila melanogaster), often in a concentration-dependent manner. HD-leucine zipper (Zip) IV family genes are unique to plants and often function in the L1 epidermal cell layer. However, our understanding of the roles of HD-Zip IV family genes in plant morphogenesis is limited.

Osteoporosis (OP) is a bone disease associated with increasing age. Currently, the most common medications used to treat OP are anabolic agents, anti-resorptive agents, and medications with other mechanisms of action. However, many of these medications have unfavorable adverse effects or are not intended for long-term use, potentially exerting a severe negative impact on a patient's life and career and placing a heavy burden on families and society.

Background: Traditional Chinese medicine (TCM) has been used to prevent and treat type 2 diabetes (T2DM) for thousands of years. The holistic view of TCM and the "multitarget" characteristics of Chinese medicine have unique advantages in the prevention and treatment of T2DM. TCM syndrome differentiation and treatment are effective for T2DM; however, currently, the therapeutic effect of TCM is generally evaluated by asking for patients' subjective feelings, or by checking the changes in relevant indicators.

Ultra-weak bioluminescence, also known as ultra-weak photon emission (UPE), is one of the functional characteristics of biological organisms, characterized by specialized, low-energy level luminescence. Researchers have extensively studied UPE for decades, and the mechanisms by which UPE is generated and its properties have been extensively investigated. However, there has been a gradual shift in research focus on UPE in recent years toward exploring its application value.

The treatment of diabetic kidney disease (DKD) has been the key concern of the medical community. Herbal medicine has been reported to alleviate intestinal dysbiosis, promote the excretion of toxic metabolites, and reduce the secretion of uremic toxins. However, the current understanding of the modulation of the gut microbiota by herbal medicine to delay the progression of DKD is still insufficient.

Article Synopsis
  • The study aimed to evaluate differences in intestinal flora in women before and after menopause, providing insights into perimenopausal syndrome and potential use of probiotics as additional treatment.
  • It included three case-control studies with 156 participants, finding no significant change at the phylum level, but higher levels of specific bacteria (A. odoratum and B. cholerae) in postmenopausal women.
  • The study concluded that while overall phylum levels were similar, certain genera showed changes post-menopause, and more extensive, high-quality research is necessary for further validation.

Forming mutualistic symbioses with arbuscular mycorrhizae (AMs) improves the acquisition of mineral nutrients for most terrestrial plants. However, the formation of AM symbiosis usually occurs under phosphate (Pi)-deficient conditions. Here, we identify SlSPX1 (SYG1 (suppressor of yeast GPA1)/Pho81(phosphate 81)/XPR1 (xenotropic and polytropic retrovirus receptor 1) as the major repressor of the AM symbiosis in tomato (Solanum lycopersicum) under phosphate-replete conditions.

The cold and hot properties of Chinese medicines are an important concept to represent the function of drugs, and are also a unique classification method of traditional Chinese medicine (TCM). The method reflects an herb's therapeutic properties and guides reasonable clinical prescription. However, the present key problem is the lack of an objective and quantitative evaluation index for the cold and hot properties of Chinese herbs.
