Potentially active compounds that improve PAD through angiogenesis: A review.

Peripheral arterial disease (PAD) has been historically neglected, which has resulted in a lack of effective drugs in clinical practice. However, with the increasing prevalence of diseases like atherosclerosis and diabetes, the incidence of PAD is rising and cannot be ignored. Researchers are exploring the potential of promoting angiogenesis through exogenous compounds to improve PAD. This paper focuses on the therapeutic effect of natural products (Salidroside, Astragaloside IV, etc.) and synthetic compounds (Cilostazol, Dapagliflozin, etc.). Specifically, it examines how they can promote autocrine secretion of vascular endothelial cells, enhance cell paracrine interactions, and regulate endothelial progenitor cell function. The activation of these effects may be closely related to PI3K, AMPK, and other pathways. Overall, these exogenous compounds have promising therapeutic potential for PAD. This study aims to summarize the potential active compounds, provide a variety of options for the search for drugs for the treatment of PAD, and bring light to the treatment of patients.

[Evaluation of surgical outcomes using imaging study for patients with slow transit constipation complicated with outlet obstruction].

OBJECTIVE: To explore the clinical significance of multiple radiography of the pelvis in the evaluation of surgical outcomes for patients with slow transit constipation complicated with outlet obstruction. METHODS: Patients with slow transit constipation complicated with outlet obstruction were diagnosed by multiple radiography of the pelvis after screening using colon transit study. Surgery was performed according to the cause of the obstruction. Anorectal angle and the locations of perineum, pelvic peritoneum, and bladder were assessed by multiple radiography of the pelvis one month after surgery. The changes in locations of pelvic organs were assessed and the imaging appearance after the release of obstruction was observed. RESULTS: A total of 48 patients were included. Rectocele repair, partial mucosectomy with rectopexy, and hysteropexy were performed. All the patients were followed up with a mean length of 19(6-58) months. Excluding 2 patients who had no symptomatic improvement, the mean bowel movements was 1.9 times per day in the remaining 46 patients(95.8%). Preoperative anorectal angle at the squeezing phase was(128.09±13.82) degree and the difference between squeezing and resting phase was (11.14±12.58) degree, while the postoperative angle was (180.26±9.98) degree and the difference(20.01±13.11) degree(P<0.05). Preoperative location of the perineum at the squeezing phase was(-2.05±0.83) cm and the difference was(2.23±0.78) cm, while postoperative location was (-0.50±1.13) cm and the difference was (2.18±1.04) cm(P<0.05). Preoperative location of the pelvic peritoneum at the squeezing phase was(4.91±1.32) cm and the difference was (1.32±0.89) cm, while postoperative location was (2.62±2.53) cm and the difference was (3.28±0.68) cm (P<0.05). Preoperative bladder location at the squeezing phase in patients with urological symptoms was (3.92±2.51) cm and the difference was(1.39±1.27) cm, while postoperative location was (2.15±1.55) cm and the difference was (1.98±1.54) cm(P<0.05). CONCLUSION: Multiple imaging of the pelvis provides objective evidence in the evaluation of surgical outcomes for patients with chronic slow transit constipation complicated with outlet obstruction.
