Non-alcoholic fatty liver disease is a common chronic liver disease in clinical practice. In recent years, with increasing social attention to the health of women and the elderly, the prevention and treatment of non-alcoholic fatty liver disease after menopause has increasingly become a research hotspot in metabolic diseases. This study explores the pathogenesis and treatment method of non-alcoholic fatty liver disease in postmenopausal women based on the theory of "deficient qi and stagnation" and combined with the physiological and pathological characteristics of postmenopausal women and the Western medicine understanding of non-alcoholic fatty liver disease. We believe that the pathogenesis of non-alcoholic fatty liver disease in postmenopausal women is rooted in the "deficient qi" caused by depletion of liver and kidney essence and blood. The imbalance between the physical and functional aspects of the liver due to this "deficient qi" is the primary factor, while the "stagnation" of phlegm and blood stasis is the manifestation. Furthermore, the "deficient qi" and "stagnation" reinforce each other, with the deficiency leading to stagnation and stagnation exacerbating the deficiency, thus accelerating the progression of the disease. The treatment approach should be one that combines nourishing deficiency and resolving stagnation, addressing both root cause and maifestations. Given the female characteristic of "the liver as the innate organ" and the post-menopausal physiological state of "gradual decline of kidney essence", it is important to focus on nourishing the liver and kidneys, nurturing the liver′s physical body while maintaining its function, and also promoting the circulation of qi, resolving phlegm, and invigorating blood circulation to remove blood stasis. This approach aims to reduce the accumulation of lipids in the liver, offering a new perspective and approach for the treatment of non-alcoholic fatty liver disease in post-menopausal women with traditional Chinese medicine.

Neuroendocrine neoplasms (NENs) are relatively rare heterogeneous tumors that originate from peptidergic neurons and neuroendocrine cells and have been referred to as "carcinoids" in the past. Although this type of tumor had been previously considered to be indolent tumor with a low degree of malignancy, with the development of medicine and clinical study, researchers found that NENs had the potential to metastasize. They can occur in any part of the body where neuroendocrine cells are distributed and gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs) are the most common type of NENs.Due to the improvement of techniques such as endoscopy and imaging, the incidence of rectal neuroendocrine tumors(R-NENs) and the number of related clinical researches have both increased significantly in recent years. Although researches in Chinese and foreign medical centers are mostly retrospective studies of small samples and the efficacies of different treatment methods are still under debating and lack of sufficient medical evidence to support, the diagnosis and treatment of this disease is gradually becoming standardized according to the proposal of corresponding guidelines. The recent advances in the epidemiology, diagnosis and treatment of rectal neuroendocrine neoplasms are reviewed in this paper.

Alpha-ketoglutarate (AKG) is a key molecule in the Krebs cycle determining the overall rate of the citric acid cycle of the organism. It is a nitrogen scavenger and a source of glutamate and glutamine that stimulates protein synthesis and inhibits protein degradation in muscles. AKG as a precursor of glutamate and glutamine is a central metabolic fuel for cells of the gastrointestinal tract as well. AKG can decrease protein catabolism and increase protein synthesis to enhance bone tissue formation in the skeletal muscles and can be used in clinical applications. In addition to these health benefits, a recent study has shown that AKG can extend the lifespan of adult Caenorhabditis elegans by inhibiting ATP synthase and TOR. AKG not only extends lifespan, but also delays age-related disease. In this review, we will summarize the advances in AKG research field, in the content of its physiological functions and applications.

Oxidative damage theory is currently one of the predominant theories on the mechanisms of aging. Previous research has shown that antioxidants can extend the lifespan in the model organism by scavenging free radicals,inducing the expression of stress related genes and hormesis. However, recent studies have suggested that these pharmaceuticals may cause serious side effects,such as promoting oxidation,increasing the risk of cancer,and destroying the metabolic balance. The low absorption and targeting property also limit the efficiency of most antioxidants. As a result ,the correlation between antioxidants and lifespan extension remains to be demonstrated. We reviewed the research progress in the field of lifespan extension by antioxidants in recent years and provided references for future research in related areas.

Previous studies proposed that the synergistic effect of fibroblast growth factor-21 (FGF-21) and insulin may be due to the improvement of insulin sensitivity by FGF-21. However, there is no experimental evidence to support this. This study was designed to elucidate the mechanism of synergistic effect of FGF-21 and insulin in the regulation of glucose metabolism. The synergistic effect of FGF-21 and insulin on regulating glucose metabolism was demonstrated by investigating the glucose absorption rate by insulin resistance HepG2 cell model and the blood glucose chances in type 2 diabetic db/db mice after treatments with different concentrations of FGF-21 or/and insulin; The synergistic metabolism was revealed through detecting GLUT1 and GLUT4 transcription levels in the liver by real-time PCR method. The experimental results showed that FGF-21 and insulin have a synergistic effect on the regulation of glucose metabolism. The results of real-time PCR showed that the effective dose of FGF-21 could up-regulate the transcription level of GLUT1 in a dose-dependent manner, but had no effect on the transcription level of GLUT4. Insulin (4 u) alone could up-regulate the transcription level of GLUT4, yet had no effect on that of GLUT1. Ineffective dose 0.1 mg kg(-1) FGF-21 alone could not change the transcription level of GLUT1 or GLUT4. However, when the ineffective dose 0.1 mg x kg(-1) FGF-21 was used in combination with insulin (4 u) significantly increased the transcription levels of both GLUT1 and GLUT4, the transcription level of GLUT1 was similar to that treated with 5 time concentration of FGF-21 alone; the transcription level of GLUT4 is higher than that treated with insulin (4 u) alone. In summary, in the presence of FGF-21, insulin increases the sensitivity of FGF-21 through enhancing GLUT1 transcription. Vice versa, FGF-21 increases the sensitivity of insulin by stimulating GLUT4 transcription in the presence of insulin. FGF-21 and insulin exert a synergistic effect on glucose metabolism through mutual sensitization.
