With the younger onset of diabetes, the reproductive dysfunction caused by diabetes has received widespread attention. Hyperglycemia and insulin resistance, the main features of diabetes, are high-risk factors for male reproductive dysfunction. Obesity, the common co-morbidity of diabetes, may aggravate the progression of reproductive dysfunction. Glucagon-like peptide-1(GLP-1) and its receptor agonists improve the overall health status by lowering blood glucose, reducing body weight, and inhibiting inflammatory response, which indirectly exerts protective effects on the reproductive system. GLP-1 also protects reproductive function by regulating the neuroendocrine function, and directly acting on the supporting cells and interstitial cells of the testis. However, some studies did not find the protective effects. High-quality clinical studies are needed. GLP-1 receptor agonists may be a therapeutic option to improve reproductive dysfunction in diabetic men.

Previous studies have shown that long-term spermatogonial stem cells (SSCs) have the potential to spontaneously transform into pluripotent stem cells, which is speculated to be related to the tumorigenesis of testicular germ cells, especially when p53 is deficient in SSCs which shows a significant increase in the spontaneous transformation efficiency. Energy metabolism has been proved to be strongly associated with the maintenance and acquisition of pluripotency. Recently, we compared the difference in chromatin accessibility and gene expression profiles between wild-type (p53+/+) and p53 deficient (p53-/-) mouse SSCs using the Assay for Targeting Accessible-Chromatin with high-throughput sequencing (ATAC-seq) and transcriptome sequencing (RNA-seq) techniques, and revealed that SMAD3 is a key transcription factor in the transformation of SSCs into pluripotent cells. In addition, we also observed significant changes in the expression levels of many genes related to energy metabolism after p53 deletion. To further reveal the role of p53 in the regulation of pluripotency and energy metabolism, this paper explored the effects and mechanism of p53 deletion on energy metabolism during the pluripotent transformation of SSCs. The results of ATAC-seq and RNA-seq from p53+/+ and p53-/- SSCs revealed that gene chromatin accessibility related to positive regulation of glycolysis and electron transfer and ATP synthesis was increased, and the transcription levels of genes encoding key glycolytic enzymes and regulating electron transport-related enzymes were markedly increased. Furthermore, transcription factors SMAD3 and SMAD4 promoted glycolysis and energy homeostasis by binding to the chromatin of the Prkag2 gene which encodes the AMPK subunit. These results suggest that p53 deficiency activates the key enzyme genes of glycolysis in SSCs and enhances the chromatin accessibility of genes associated with glycolysis activation to improve glycolysis activity and promote transformation to pluripotency. Moreover, SMAD3/SMAD4-mediated transcription of the Prkag2 gene ensures the energy demand of cells in the process of pluripotency transformation and maintains cell energy homeostasis by promoting AMPK activity. These results shed light on the importance of the crosstalk between energy metabolism and stem cell pluripotency transformation, which might be helpful for clinical research of gonadal tumors.

Male diabetic individuals present a marked impairment in fertility; however, knowledge regarding the pathogenic mechanisms and therapeutic strategies is unsatisfactory. The new hypoglycemic drug dapagliflozin has shown certain benefits, such as decreasing the risk of cardiovascular and renal events in patients with diabetes. Even so, until now, the effects and underlying mechanisms of dapagliflozin on diabetic male infertility have awaited clarification. Here, we found that dapagliflozin lowered blood glucose levels, alleviated seminiferous tubule destruction, and increased sperm concentrations and motility in leptin receptor-deficient diabetic db/db mice. Moreover, the glucagon-like peptide-1 receptor (GLP-1R) antagonist exendin (9-39) had no effect on glucose levels but reversed the protective effects of dapagliflozin on testicular structure and sperm quality in db/db mice. We also found that dapagliflozin inhibited the testicular apoptotic process by upregulating the expression of the antiapoptotic protein B-cell lymphoma 2 (BCL2) and X-linked inhibitor of apoptosis protein (XIAP) and inhibiting oxidative stress by enhancing the antioxidant status, including total antioxidant capacity, total superoxide dismutase (SOD) activity, and glutathione peroxidase (GPx) activity, as well as decreasing the level of 4-hydroxynonenal (4-HNE). Exendin (9-39) administration partially reversed these effects. Furthermore, dapagliflozin upregulated the glucagon-like peptide-1 (GLP-1) level in plasma and GLP-1R expression by promoting AKT8 virus oncogene cellular homolog (Akt) phosphorylation in testicular tissue. Exendin (9-39) partially inhibited Akt phosphorylation. These results suggest that dapagliflozin protects against diabetes-induced spermatogenic dysfunction via activation of the GLP-1R/phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathway. Our results indicate the potential effects of dapagliflozin against diabetes-induced spermatogenic dysfunction.

Ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) coupled with a molecular network analysis strategy was used to identify the chemical constituents of the stem bark of two kinds of asparagus. The chemical constituents were identified by determining an accurate molecular weight, the fragmentation pathway, and comparison with the mass spectrometry data from the references. A molecular network was established based on the similarity of MS/MS fragmentation patterns. A total of 107 compounds were identified or tentatively deduced, which included 46 saponins, 13 flavonoids, and 48 other compounds. The chemical compounds identified in the stem bark of white and green asparagus differed greatly: the white asparagus was rich in saponins, while the green asparagus was rich in flavonoids. In conclusion, the chemical constituents of asparagus stem bark were characterized rapidly using UPLC-Q-TOF-MS/MS and molecular network analysis, with 10 compounds and 45 targets determined from the HIT 2.0 herbal ingredients' targets platform. This work will provide a theoretical basis for the resource utilization of asparagus.

Islet β cell protection is one of the key strategies for diabetes treatment. The new antidiabetic drug sodium-glucose cotransporter 2(SGLT2)inhibitor decreases blood glucose by inhibiting glucose reabsorption in the renal tubule, independent of insulin. Various clinical studies have shown that SGLT2 inhibitors improve β cell function. Furthermore, animal experiments have indicated that SGLT2 inhibitors increase β cell mass. SGLT2 inhibitors promote islet regeneration through stimulating β cell proliferation, inhibiting β cell apoptosis and dedifferentiation, enhancing transdifferentiation of α cells to β cells, and initiating progenitor-derived β cell neogenisis. Indirect effects of metabolic improvement(i.e.lowering glucose, losing weight, improving lipid metabolism), inhibiting inflammatory reaction, inducing glucagon-like peptide-1 secreted from α cells, and regulating gene changes might be involved in the β cell protection of SGLT2 inhibitors.

Although many microRNAs (miRNAs) are known to function as regulators of coat color and melanogenesis, the underlying molecular mechanisms of miR-100-5p governing melanogenesis were not completely known.The goal of this study was to determine the effect of miR-l()()-5p on melanogenesis in alpaca melanocytes.Fibroblast growth factor 21 (FGF21) is a predicted target gene of miR-100-5p and the luciferase reporter assay demonstrated that miR-100-5p regulates FGF21 by binding to its 3' untranslated region (3'UTR).In this study, alpaca melanocytes were transfected with miR-100-5p, inhibitor and negative control plasmid.Results showed that miR-100-5p overexpression significantly decreased mRNA and protein expression of FGF2\.Meanwhile, the ERK signal pathway was inhibited, with subsequent up-regulation of microphthalmia-associated transcription factor (MITF) , tyrosinase (TYR) and tyrosinase-related protein 2 (TYRP2), which increased melanin production.The results suggest that miR-100-5p may regulate melanogenesis by targeting FGF21 via extracellular regulated MAP kinase (ERK) signaling pathway.

In this study,mouse models of benign prostatic hyperplasia induced by subcutaneous injection of testosterone propionate was used to investigate the therapeutic effect and mechanism of Urtica hyperborean( UW) extracts on prostate hyperplasia in mice. The effects of UW extracts on prostate index,serum epidermal growth factor( EGF) and dihydrotestosterone( DHT) in model mice were observed,and the EGF and anti-apoptotic factor( Bcl-2) mRNA expression levels were detected as well as pathological changes in prostate tissue. The results showed that the ethyl acetate extraction and alcohol soluble fraction of the UW could significantly reduce the prostate index,reduce the serum DHT and EGF levels( P<0. 01),and significantly decrease the EGF and Bcl-2 mRNA expression( P<0. 01),significantly improved the morphological structure of prostate tissue. The above results confirmed that ethyl acetate extract and alcohol-soluble parts of UW have a good preventive effect on mice prostatic hyperplasia model,and its mechanism may be to reduce androgen levels by regulating polypeptide growth factors and/or inhibiting cell hyperproliferation and promoting apoptosis. This study laid the foundation for the further research on UW.

Chrysosplenium nudicaule,Tibetan name " Yajima",is recorded as an effective medicine for the treatment of liver and gallbladder diseases by Tibetan Pharmacopoeia published in the past dynasties,but its traditional efficacy has not yet been investigated by means of modern pharmacological research methods. In this paper,the protective effect of extract of C. nudicaule(ECN) on liver injury in mice was observed by using the mice model of intrahepatic cholestasis(IC) induced by α-naphthyl isothiocyanate(ANIT) and the possible mechanism by which ECN work as the therapeutic agent was discussed. The results showed that the serum levels of AST,ALT,ALP,DBIL,TBIL and TBA of the model mice were notably reduced in dose-dependent manner(P<0. 01,P<0. 05). The activity of SOD and GSH-Px in the liver homogenate of mice was increased,while the content of MDA was decreased(P<0. 01,P<0. 05).Pathological examination of liver in mice showed that ECN could improve the pathological changes of liver tissue in mice. The mRNA expression level of genes related to bile acid metabolism were detected by RT-PCR and the results suggested that ECN could significantly increase the expression of genes such as BSEP,FXR and MRP2(P<0. 01,P<0. 05),meanwhile significantly reduce the expression of CYP7 A1(P<0. 01,P<0. 05). These results confirmed the protective effect of ECN on intrahepatic cholestasis-induced liver injury in mice,and indicated that the mechanism may be related to activating FXR and its target genes,reducing bile acid synthesis and increasing bile acid excretion. This study provides a modern pharmacological basis for the clinical application of Yajima in Tibetan medicine.

Objective: To study the factors affecting the survival and prognosis of patients with intracranial ependymoma. Methods:From January 2008 to January 2018, the prognoses of 276 patients with intracranial ependymoma were analyzed using Log-rank and Cox model analysis. The variables included sex, age, tumor location, tumor diameter, resection extent, pathological grade, Ki-67 index, postoperative radiotherapy, and postoperative chemotherapy. Results: Tumor location, resection extent, and postoperative radiothera-py could all affect the overall survival (OS) and progression-free survival (PFS) of patients with intracranial ependymoma (P<0.001) and independently affected the OS (P<0.001, P<0.001, and P=0.002, respectively) and PFS (P<0.001, P<0.001, and P=0.001, respectively). The Ki-67 index was an independent factor affecting PFS in patients with intracranial ependymoma (P<0.001). The supratentorial loca-tion and Ki-67 index≥10% were independent risk factors indicating poor prognosis (P<0.001). Total resection and postoperative radio-therapy were protective factors (P<0.001 and P=0.001, respectively). Conclusions: Tumor location, resection extent, Ki-67 index, and postoperative radiotherapy are independent factors affecting the prognosis of intracranial ependymoma. It is helpful to extend the PFS and OS of patients through complete tumor resection or postoperative radiotherapy.

A 22-year-old man suffered from acute pulmonary hemorrhage and deteriorated renal function occurred within 3 days after traumatic brain injury. Mechanical ventilation cannot correct his severe hypoxemia, therefore, venoarterial extracorporeal membrane oxygenation (VA-ECMO) support was initiated and finally resolved his hypoxemia. Concomitantly, continuous renal replacement therapy was performed to improve his kidney function. Although no anti-glomerular basement membrane (anti-GBM) antibody was detected in serum, Goodpasture's syndrome was considered. After treated with methylprednisolone pulse therapy and plasmapheresis, his renal function was significantly improved. ECMO was eventually discontinued after 60 hours of treatment and extubated on day 10. He was discharged home with normal pulmonary and renal functions.

Glucagon regulates glucolipid metabolism and body weight through binding to and activating glucagon receptor ( GCGR ), which is predominantly expressed in liver and pancreas. In the diabetic state, inappropriately increased glucagon secretion leads to elevated hepatic glucose output, while GCGR blockage restores blood glucose homeostasis. Various approaches including GCGR monoclonal antibodies ( mAbs ), antagonists, antisense oligonucleotides, and gene knockout can block GCGR signaling. It has shown that GCGR mAbs improve hyperglycemia in diabetic mice and humans without severe adverse effects, since they can specifically antagonize the action of glucagon. Therefore, GCGR signaling plays a critical role in the pathophysiology of diabetes and GCGR mAbs represent innovative approaches in the management of diabetes.
