Purpose:
Erectile dysfunction (ED) is a common male sexual dysfunction. Gut microbiota plays an important role in various diseases. To investigate the effects and mechanisms of intestinal flora dysregulation induced by high-fat diet (HFD) on erectile function.
Materials and Methods:
Male Sprague–Dawley rats aged 8 weeks were randomly divided into the normal diet (ND) and HFD groups. After 24 weeks, a measurement of erectile function was performed. We performed 16S rRNA sequencing of stool samples. Then, we established fecal microbiota transplantation (FMT) rat models by transplanting fecal microbiota from rats of ND group and HFD group to two new groups of rats respectively. After 24 weeks, erectile function of the rats was evaluated and 16S rRNA sequencing was performed, and serum samples were collected for the untargeted metabolomics detection.
Results:
The erectile function of rats and the species diversity of intestinal microbiota in the HFD group was significantly lower, and the characteristics of the intestinal microbiota community structure were also significantly different between the two groups. The erectile function of rats in the HFD-FMT group was significantly lower than that of rats in the ND-FMT group. The characteristics of the intestinal microbiota community structure were significantly different. In the HFD-FMT group, 27 metabolites were significantly different and they were mainly involved in the several inflammation-related pathways.
Conclusions
Intestinal microbiota disorders induced by HFD can damage the intestinal barrier of rats, change the serum metabolic profile, induce low-grade inflammation and apoptosis in the corpus cavernosum of the penis, and lead to ED.

BackgroundThe incidence of cognitive impairment in patients with depressive disorder is high, and the causes and mechanisms of which deserve more attention. It is usual that the thyroid hormone levels in patients with depressive disorder alter. Further research is needed to explore whether the cognitive function changes in patients with depressive disorder are related to thyroid hormone levels. ObjectiveTo explore the improvement of cognitive function in patients with first-episode depressive disorder after escitalopram and paroxetine treatment, and to analyse its correlation with thyroid hormone levels, so as to look for potential biomarkers of cognitive function change in patients with depressive disorder. MethodsFrom March 2021 to March 2022, 120 patients who met the diagnostic criteria of the International Classification of Diseases, tenth edition (ICD-10) for depression and were hospitalized at Shandong Mental Health Center were selected as the research objects. They were randomly divided into two groups by random number table method with 60 patients in each group. The two groups were treated with escitalopram (starting dose 5 mg/d) and paroxetine (starting dose 20 mg/d) for 6 weeks. Before and 6 weeks after the treatment, levels of thyroid stimulating hormone (TSH), free thyroxine (FT4) and free triiodothyronine (FT3) were tested respectively. Depression degree and cognitive function level were assessed using the Hamilton Depression Scale-17 item (HAMD-17) and Montreal Cognitive Assessment (MoCA), respectively. Pearson or Spearman correlation analysis was used to examine the correlation between the MoCA score difference before and after the treatment and the post-treatment level of thyroid hormone. ResultsBefore and 6 weeks after the treatment, the time effect of HAMD-17 total score in both groups was statistically significant (F=1 236.568, P<0.01). Also, the time effect, group effect as well as interaction effect of time and group of MoCA total score in both groups were statistically significant (F=79.186, 6.026, 20.417, P<0.05 or 0.01). The time effect, group effect as well as the interaction effect of time and group for FT3 level and FT4 level were statistically significant in both groups (F=75.973, 20.287, 0.961, 84.194, 0.142, 8.299, P<0.05 or 0.01). According to the simple effect analysis. After the treatment, the MoCA total score in both groups was higher than that before treatment, while FT3 and FT4 levels were lower than those before treatment (F=15.864, 5.421, 8.524, 6.443, 7.628, 3.639, P<0.01). After the 6-week treatment, the MoCA total score as well as FT3 and FT4 level differences in escitalopram and paroxetine groups were of statistical significance (t=5.841, -0.705, -2.349, P<0.05 or 0.01). The MoCA score difference before and after treatment in paroxetine group was positively correlated with FT3 and FT4 levels after treatment (r=0.276, 0.382, P<0.05 or 0.01). ConclusionBoth escitalopram and paroxetine can improve cognitive function in patients with first-episode depressive disorder. The improvement may be related to the changes in serum FT3 and FT4 levels.

Metabolic reprogramming is a hallmark of cancer, including lung cancer. However, the exact underlying mechanism and therapeutic potential are largely unknown. Here we report that protein arginine methyltransferase 6 (PRMT6) is highly expressed in lung cancer and is required for cell metabolism, tumorigenicity, and cisplatin response of lung cancer. PRMT6 regulated the oxidative pentose phosphate pathway (PPP) flux and glycolysis pathway in human lung cancer by increasing the activity of 6-phospho-gluconate dehydrogenase (6PGD) and α-enolase (ENO1). Furthermore, PRMT6 methylated R324 of 6PGD to enhancing its activity; while methylation at R9 and R372 of ENO1 promotes formation of active ENO1 dimers and 2-phosphoglycerate (2-PG) binding to ENO1, respectively. Lastly, targeting PRMT6 blocked the oxidative PPP flux, glycolysis pathway, and tumor growth, as well as enhanced the anti-tumor effects of cisplatin in lung cancer. Together, this study demonstrates that PRMT6 acts as a post-translational modification (PTM) regulator of glucose metabolism, which leads to the pathogenesis of lung cancer. It was proven that the PRMT6-6PGD/ENO1 regulatory axis is an important determinant of carcinogenesis and may become a promising cancer therapeutic strategy.

Self-injury has become a significant public health problem, especially happens in adolescents. Previous studies have suggested that self-injury is related to numerous factors. At present, the occurrence mechanism of self-injury is still unclear, and there is a lack of reliable biological markers in its diagnosis and therapeutic target so far. Previous studies have suggested that self-injury may be related to hypothalamic pituitary adrenal(HPA) axis, β-endorphins, opioids and other hormones. Hypothalamic pituitary thyroid(HPT) axis and hypothalamic pituitary gonadal(HPG) axis are endocrine systems connecting nerves and hormones. Many studies suggested that various hormones in HPT axis and HPG axis of self-injury patients with other mental disorders (such as major depression and bipolar disorder) were abnormal. At present, there are few studies on the relationship between self-injury and HPT axis and HPG axis. There are differences in results even among studies on the same hormones, and some studies involve suicide attempts and even behaviors. Some studies have confirmed that self-injury is related to suicide, expanding the possibility of exploring the correlation between self-injury and hormones. This study will review the relationship between self-injury and hormonal changes.

Objective:Based on TGF-β1/Smad3 signal pathway, study the effect of Yiqi-Yangyin-Huoxue-Tongluo Recipe in diabetic rat model. Methods:Forty male SD rats were randomly divided into blank group ( n=10) and diabetic model group ( n=30). Diabetic rats were fed with high sugar and high-fat diet combined with low-dose intraperitoneal injection of STZ. The successful rats were randomly divided into model group ( n=10), traditional Chinese medicine (TCM) group ( n=9) and western medicine group ( n=9). The western medicine group was given trimetazidine hydrochloride tablets 4.16 mg/kg, the TCM group was given Yiqi-Yangyin-Huoxue-Tongluo Recipe 19.1 mg/kg, and the blank group and model group were given the same volume of normal saline, once a day for 20 weeks. The level of fasting blood glucose (FBG) in rats were detected by blood glucose meter; Alkaline hydrolysis was used to detect serum hydroxyproline (Hyp); Enzyme-linked immunosorbent assay (ELISA) to detect serum TGF-β1; Masson staining to observe myocardial fibrosis; Western blotting was used to detect TGF-β1, Smad3, collagen Ⅰ (Col-Ⅰ) and collagen Ⅲ (Col-Ⅲ) protein expression. The mRNA expression of TGF-β1 and Smad3 were detected by real-time quantitative PCR. Results:Compared with the model group, the FBG (19.41 ± 3.65 mmol/L vs. 27.48 ± 2.36 mmol/L), serum Hyp (25.76 ± 1.73 μg/ml vs. 31.71 ± 0.33 μg/ml), TGF-β1 (28.41 ± 0.05 pg/ml vs. 30.82 ± 0.84 pg/ml) of TCM group were significantly reduced ( P<0.05), and myocardial interstitial collagen fibers decreased. The expression of TGF-β1 (0.81 ± 0.02 vs. 0.96 ± 0.08), Smad3 (0.36 ± 0.05 vs. 0.57 ± 0.06), Col-Ⅰ (2.36 ± 0.45 vs. 3.53 ± 0.58), Col-Ⅲ (1.92 ± 0.31 vs. 2.75 ± 0.08) protein in the myocardial tissue of TCM group significantly decreased ( P<0.05), the mRNA expression of TGF-β1 (3.55 ± 0.82 vs. 6.67 ± 1.33) and Smad3 (1.62 ± 0.35 vs. 2.70 ± 0.85) in myocardial tissue significantly decreased ( P<0.05). Conclusions:Yiqi-Yangyin-Huoxue-Tongluo Recipe can effectively treat myocardial fibrosis, and its mechanism may be related to the regulation of TGF-β1/Smad3 signal pathway.
