[Yishen Huoxue Decoction for infertility in elderly men with kidney deficiency and blood stasis].

OBJECTIVE: To observe the clinical effect of Yishen Huoxue Decoction on infertility in elderly men with kidney deficiency and blood stasis. METHODS: We randomly assigned 60 infertility male patients with kidney deficiency and blood stasis to two groups of an equal number to receive Yishen Huoxue Decoction, 1 dose a day, twice daily in the morning and evening (the observation group, aged ï¼»42.10 ± 3.82ï¼½ yr) or Shengjing Tablets (4 tablets once, tid) combined with L-carnitine oral solution at 10 ml, bid (the control group, aged ï¼»42.79 ± 3.56ï¼½ yr), both for 3 months. Before and after treatment, we obtained the semen parameters, levels of reproductive hormones and traditional Chinese medicine (TCM) clinical symptoms scores from the patients and compared them between the two groups. RESULTS: A total of 57 patients completed this clinical study, 29 in the observation group, with pregnancy achieved in 2 cases (6.90%), and 28 in the control group, with pregnancy achieved in 1 (3.57%). The patients in the observation group, compared with the controls, showed significantly higher total effectiveness (82.76% vs 71.43%, P < 0.05) and overall therapeutic efficacy on TCM syndromes (93.10% vs 85.71%, P < 0.05), as well as higher semen volume, sperm concentration, total sperm count, total sperm motility, percentages of progressively motile sperm (PMS) and morphologically normal sperm (MNS), and TCM clinical symptoms scores (all P < 0.05), but no statistically significant difference in the levels of reproductive hormones (E2, LH, PRL, T and FSH) (P > 0.05). Remarkable increases were observed in both the observation and control groups after medication in sperm concentration, total sperm count, total sperm motility, PMS, MNS, and TCM clinical symptom scores (all P < 0.05). CONCLUSIONS: Yishen Huoxue Decoction can significantly improve the semen quality and TCM clinical symptoms of elderly infertility males with kidney deficiency and blood stasis.

Elevated miR-124-3p in the aging colon disrupts mucus barrier and increases susceptibility to colitis by targeting T-synthase.

The risk of colitis and colorectal cancer increases markedly throughout adult life, endangering the health and lives of elderly individuals. Previous studies have proposed that bacterial translocation and infection are the main risk factors for these diseases. Therefore, in the present study, we aimed to identify the underlying mechanism by focusing on the mucus barrier function and mucin-type O-glycosylation. We evaluated alterations in the colon mucus layer in 2-, 16-, and 24-month-old mice and aged humans. Aged colons showed defective intestinal mucosal barrier and changed mucus properties. The miR-124-3p expression level was significantly increased in the aged distal colonic mucosa, which was accompanied by an increase in pathogens and bacterial translocation. Meanwhile, T-synthase, the rate-limiting enzyme in O-glycosylation, displayed an age-related decline in protein expression. Further experiments indicated that miR-124-3p modulated O-glycosylation by directly targeting T-synthase. Moreover, young mice overexpressing miR-124-3p exhibited abnormal glycosylation, early-onset, and more severe colitis. These data suggest that miR-124-3p predisposes to senile colitis by reducing T-synthase, and the miR-124-3p/T-synthase/O-glycans axis plays an essential role in maintaining the physiochemical properties of colonic mucus and intestinal homeostasis.
