A major obstacle in type 2 diabetes mellitus (T2DM) is sleep fragmentation (SF), which negatively affects testicular function. However, the underlying mechanisms remain to be elucidated. In this study, we demonstrate that SF induces testicular damage through a mechanism involving lipid metabolism, specifically mediated by melatonin (MEL) receptor 1a (MT1). T2DM mice with SF intervention displayed several deleterious phenotypes such as apoptosis, deregulated lipid metabolism, and impaired testicular function. Unexpectedly, sleep recovery (SR) for 2 consecutive weeks could not completely abrogate SF's detrimental effects on lipid deposition and testicular function. Interestingly, MEL and MT1 agonist 2-iodomelatonin (2IM) effectively improved lipid homeostasis, highlighting MEL/2IM as a promising therapeutic drug for SF-trigged testicular damage. Mechanistically, MEL and 2IM activated FGFR1 and sequentially restrained the crosstalk and physical interaction between TAB1 and TAK1, which ultimately suppressed the phosphorylation of TAK1 to block lipid deposition and cell apoptosis caused by SF. The ameliorating effect of MEL/2IM was overtly nullified in Fgfr1 knockout (Fgfr1-KO +/- ) diabetic mice. Meanwhile, testicular-specific overexpression of Tak1 abolished the protective effect of FGF1mut on diabetic mouse testis. Our findings offer valuable insights into the molecular mechanisms underlying the testicular pathogenesis associated with SF and propose a novel therapeutic approach for addressing male infertility in T2DM.

Renal interstitial fibrosis (RIF) is a common pathological change process from the development of various chronic nephropathies to the end stage, and it is an important histological manifestation of renal function decline. At present, no effective anti-fibrosis drugs have been found in clinical practice. In recent years, with the continuous development of traditional Chinese medicine (TCM) pharmacology, molecular biology, system biology, and network pharmacology, the research on regulating RIF with TCM monomer, single TCM, TCM compound, Chinese patent medicine, and TCM injection is deepening. Among them, Jianpi Yishen recipe, Shendi Bushen capsules, Jianzhong Bushen Xiaozheng decoction, Liuwei Dihuangtang, and Lycium barbarum polysaccharides can regulate transforming growth factor-β/small mother against decapentaplegic (TGF-β1/Smads), Wnt/β-catenin, and neurogenic locus notch homolog protein (Notch) signaling pathways. Wulingsan, Zhenwutang, pachymic acid ZA, pachymic acid ZC, and pachymic acid ZD, which mainly induce diuresis, can regulate the Wnt/β-catenin signaling pathway. Hirudin, curcumin, and Fuzheng Huayu recipe, which mainly promote blood circulation, can inhibit inflammation-related pathways such as p-nuclear transcription factor-κB (NF-κB), Toll-like receptor 4/p-nuclear transcription factor-κB (TLR4/NF-κB), and Janus kinase 2/signal transducer and activator of transcription 3 (JAK/STAT), so as to achieve anti-inflammatory and anti-oxidation effects and alleviate the progression of RIF. Shenshuai Xiezhuo decoction, Shenkang injection, and Shenshuai recipe, which are mainly used for invigorating Qi, removing blood stasis, and removing turbidity, can inhibit transdifferentiation of pericytes-myofibroblasts through vascular endothelial growth factor receptor (VEGFR) signaling pathway. At present, there are many studies on the regulation of the RIF signaling pathway by TCM, but there is a lack of a systematic summary. In this study, by combing the signaling pathway of TCM in the treatment of RIF, the effective target of TCM treatment is screened, and its possible mechanism is found, which provides new ideas for clinical treatment and new drug research and development.

BACKGROUND:Skeletal muscle insulin resistance is the key pathological link of type 2 diabetes.Static exercise can effectively improve skeletal muscle insulin resistance,but the mechanism remains unclear. OBJECTIVE:To explore the mechanism of static exercise on insulin resistance in the skeletal muscle of type 2 diabetic mice based on the phosphatidyl inositol 3-kinase(PI3K)/protein kinase B(AKT)/glucose transporter(GLUT4)signaling pathway. METHODS:After 1 week of adaptive feeding,7 out of 40 C57BL/6 mice were randomly selected as blank group and fed common diet,while the other mice were fed high-fat diet and taken to prepare type 2 diabetes models through the low-dose streptozotocin intraperitoneal injection.Twenty-four mice were successfully modeled and they were randomly divided into model group(n=8),metformin group(n=8)and static exercise group(n=8),which continued to be fed high-fat diet.The metformin group was given 200 mg/kg metformin dissolved in normal saline(2 ml/kg)by gavage,once a day,for 6 weeks.The static exercise group was given normal saline daily by gavage and carried out static exercise,30 minutes a day,6 days per week.The model group was given the same dose of normal saline daily by gavage without exercise intervention.After the intervention,the fasting blood glucose of each group was detected,the intraperitoneal glucose tolerance test was performed,and the area under the glycemic curve was calculated.Glycosylated hemoglobin,serum insulin,insulin resistance index were detected by ELISA.Total cholesterol,triglyceride,high-density lipoprotein,low-density lipoprotein were detected using biochemical methods.The mRNA expression levels of PI3K,AKT and GLUT4 in the gastrocnemius of mice were detected by real-time quantitative PCR.Morphological changes of the gastrocnemius were observed by hematoxylin-eosin staining,and the cross-sectional area of muscle fibers was calculated. RESULTS AND CONCLUSION:Compared with the blank group,fasting blood glucose,glycosylated hemoglobin,area under the glycemic curve,insulin resistance index,total cholesterol,triglyceride and low-density lipoprotein levels were significantly increased in the model group(P<0.01,P<0.05).Whereas,these indicators were significantly lower in the static exercise and metformin group than the model group(P<0.01,P<0.05).Compared with the blank group,serum insulin and high-density lipoprotein levels were significantly declined in the model group(P<0.01)and the mRNA expression of PI3K,AKT and GLUT4 in the gastrocnemius of mice were also significantly reduced(P<0.01).These indicators were significantly elevated in the metformin group and static exercise group compared with the blank group(P<0.01).Compared with the blank group,the muscle fibers in the model group were disordered,and the muscle cells atrophied and the muscle fiber gap widened.The cross-sectional area of muscle fibers was significantly decreased in the model group compared with the blank group(P<0.01).Compared with the model group,atrophy of the gastrocnemius fibers and muscle fiber space were improved in the static exercise group and the metformin group,and the cross-sectional area of muscle fiber was significantly increased in both groups(P<0.01).These findings indicate that static resistance training may promote glucose uptake and utilization by up-regulating the expression of PI3K,AKT and GLUT4 mRNA in skeletal muscle tissue,thereby improving the morphology and function of skeletal muscle tissue,alleviating insulin resistance and regulating glucose homeostasis.

Objective:To document any effect of a pulsed electromagnetic field (PEMF) on the regulation of neuropeptide Y (NPY) in nucleus pulposus (NP) tissue, NP cell apoptosis and matrix degradation using rats with intervertebral disc degeneration (IDD).Methods:Eighteen Sprague-Dawley rats were randomly divided into a control group, an IDD model group (the model group), and a PEMF group. IDD was induced in both the model and PEMF groups. Right after the modeling, the PEMF group received 14 days of PEMF treatment, while the control group and model group were given no special treatment. Meanwhile, the primary rat nucleus pulposus cells (NPCs) were cultured using Dulbecco′s Modified Eagle Medium at 37℃ and 5% CO 2. When the fusion rate reached 90% after passage, the NPCs were divided into a control group, a TNF-α model group (referred to as model group) and TNF-α + PEMF group (referred to as PEMF group) and treated accordingly. Eight weeks after the modeling, safranin-o/fast green staining was used to assess any pathological morphology changes. The expression of NPY, neuropeptide Y receptor Y2 (NPY2R), bcl-2-associated X protein (Bax), B-cell lymphoma 2 (Bcl-2), collagen type II (Col-II) and matrix metalloproteinase-3 (MMP3) in the intervertebral disc and the cultivated nucleus pulposus cells of the 3 groups were determined. Results:The intervertebral disc cells in the model group were ruptured and folded, with significantly increased polysaccharide and protein components, and significantly increased bone fibers. In the PEMF group the cell boundaries were clearer, with less fibrin fracture and increased cartilage tissue. NPY was expressed in the fibrous annulus and the nucleus pulposus of the intervertebral disc in the model group. The average expression levels of NPY and NPY2R were significantly higher than in the control group and the model group. Compared with the control group, there was a significant increase in the level of Bax and a significant decrease in the expression of Bcl-2 in the model group, and there was a significant decrease in the level of Bax in the PEMF group. Compared with the control group, there was a significant decrease in the Col-II level but a significant increase in the MMP3 protein expression in the model group. The average Col-II mRNA expression was significantly higher in the PEMF group compared with the model group, but the average MMP3 protein expression was significantly less. Those results are consistent with observations in vivo.Conclusion:PEMF may reverse the imbalance of ECM metabolism and delay IDD degeneration by up-regulating the expression of NPY and Bcl-2, as well as blocking the Bax/Bcl-2 signaling pathway to inhibit apoptosis of nucleus pulposus cells.
