Gender differences in systemic inflammatory and nutritional index following radical surgery for advanced gastric cancer.

Zhong Nan Da Xue Xue Bao Yi Xue Ban

August 2024

Department of Gastrointestinal Surgery, General Surgery, Xiangya Hospital, Central South University, Changsha 410008.

Objectives: Albumin-globulin ratio (AGR), prognostic nutritional index (PNI), and platelet-to-lymphocyte ratio (PLR) have been validated as prognostic factors for gastric cancer (GC). However, significant gender differences exist in albumin levels and inflammatory cell counts, and further research is required to understand how these differences influence GC prognosis. This study aims to investigate the prognostic impact of nutritional and inflammatory indicators on GC patients undergoing radical surgery, as well as the influence of gender on these indicators' prognostic value.

Probiotics in reducing obesity by reconfiguring the gut microbiota.

Zhong Nan Da Xue Xue Bao Yi Xue Ban

July 2024

Department of Endocrinology, First Affiliated Hospital of Baotou Medical College, Baotou Inner Mongolia Autonomous Region 014010, China.

Obesity, as a global health crisis, is increasingly linked to intestinal microecology. Probiotics colonise the body, effectively regulating the balance of intestinal flora, while strengthening the intestinal barrier, activating the immune response, releasing beneficial substances, and maintaining micro-ecological balance. This process not only enhances the defence against pathogens, but also reduces the production of inflammatory factors and lowers the level of chronic inflammation.

Childhood obesity and central precocious puberty.

Zhong Nan Da Xue Xue Bao Yi Xue Ban

July 2024

Second Ward of Endocrinology Department, First Affiliated Hospital of Henan University of Chinese Medicine, Zhengzhou 450000.

Central precocious puberty (CPP) is an endocrine disorder in children caused by the early activation of the hypothalamic-pituitary-gonadal axis (HPGA), leading to elevated gonadotropin-releasing hormone (GnRH), which triggers the development of gonads and the secretion of sex hormones. This eventually results in the development of internal and external genitalia and secondary sexual characteristics. CPP significantly affects the physical and mental health of children and may increase the risk of various adult diseases.

Whilst the world sees the tremendous growth of mobile phone technology, radiofrequency electromagnetic radiation (RF-EMR) induced possible health effects have emerged as a topic of recent day debate. The current study is designed to test the hypothesis that chronic 900MHz radiation exposure would potentially dysregulate the stress response system (HPA axis) in vivo, via, its non-thermal mechanisms, leading to alterations in the microarchitecture of the adrenal gland, vulnerable brain regions such as the hippocampus which may results in altered behaviours in rats. Male albino Wistar rats aged four weeks, weighing 50-60g were subjected to 900MHz radiation from a cellphone for four weeks at a rate of one hour per day.

Environ Res

January 2025

Department of Public Health, the Second Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, 310058, China. Electronic address:

Background: Exposure to residential greenness has been linked with improved sleep duration; however, longitudinal evidence is limited, and the potential mediating effect of ambient fine particulate matter (PM) has yet to be assessed.

Methods: We obtained data for 19,567 participants across seven counties in a prospective cohort in Ningbo, China. Greenness was estimated using Normalized Difference Vegetation Index (NDVI) within 250-m, 500-m and 1000-m buffer zones, while yearly average PM concentrations were measured using validated land-use regression models, both based on individual residential addresses.

Electronic address:

Cellular senescence, a complex biological process resulting in permanent cell-cycle arrest, is central to aging and age-related diseases. A key concept in understanding cellular senescence is the Hayflick Limit, which refers to the limited capacity of normal human cells to divide, after which they become senescent. Senescent cells (SC) accumulate with age, releasing pro-inflammatory and tissue-remodeling factors collectively known as the senescence-associated secretory phenotype (SASP).

How age affects human hematopoietic stem and progenitor cells and strategies to mitigate HSPC aging.

Exp Hematol

State Key Laboratory of Experimental Hematology, National Clinical Research Center for Blood Diseases, Haihe Laboratory of Cell Ecosystem, Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, Tianjin 300020, China; Tianjin Institutes of Health Science, Tianjin, China.. Electronic address:

Hematopoietic stem cells (HSCs) are central to blood formation and play a pivotal role in hematopoietic and systemic aging. With aging, HSCs undergo significant functional changes, such as an increased stem cell pool, declined homing and reconstitution capacity, and skewed differentiation towards myeloid and megakaryocyte/platelet progenitors. These phenotypic alterations are likely due to the expansion of certain clones, known as clonal hematopoiesis (CH), which leads to disrupted hematopoietic homeostasis, including anemia, impaired immunity, higher risks of hematological malignancies, and even associations with cardiovascular disease, highlighting the broader impact of HSC aging on overall health.

Electronic address:

General anesthesia is administered to millions of individuals each year, however, the precise mechanism by which it induces unconsciousness remains unclear. While some theories suggest that anesthesia shares similarities with natural sleep, targeting sleep-promoting areas and inhibiting arousal nuclei, recent research indicates a more complex process. Emerging evidence highlights the critical role of corticothalamocortical circuits, which are involved in higher cognitive functions, in controlling arousal states and modulating transitions between different conscious states during anesthesia.

Fungal microbes are a small but immunoreactive component of the human microbiome, which may influence cancer development, progression and therapeutic response. Immunosenescence is a process of immune dysfunction that occurs with aging, including lymphoid organ remodeling, contributing to alterations in the immune system in the elderly, which plays a critical role in many aspects of cancer. There is evidence for the interactions between fungi and immunosenescence in potentially regulating cancer progression and remodeling the tumor microenvironment (TME).

How novel structures emerge during evolution has long fascinated biologists. A dramatic example is how the diminutive bones of the mammalian middle ear arose from ancestral fish jawbones. In contrast, the evolutionary origin of the outer ear, another mammalian innovation, remains a mystery, in part because it is supported by non-mineralized elastic cartilage rarely recovered in fossils.
