ABSTRACT
Benign prostatic hyperplasia （BPH）， a common disease in urology and andrology， is mainly manifested as enlarged prostate glands， bladder outlet obstruction， and lower urinary tract symptoms（LUTS）， which seriously affects the quality of life of middle-aged and elderly men. This disease falls into the categories of "retention of urine" and "prostatic hypertrophy" in traditional Chinese medicine （TCM）. In recent years，many doctors have put forward their understandings of BPH based on academic classics and their clinical experience. Clinical research on the treatment of BPH with TCM has become increasingly abundant. The basic pathogenesis of BPH lies in the disturbance of Qi transformation in the bladder and poor blood circulation due to kidney Qi deficiency in the aged. The disease is located in the kidney and the bladder and is related to the dysfunction of the lung and the kidney. It is basically characterized by deficiency in origin and excess in superficiality. A large number of clinical research reports have proved that TCM is efficient in alleviating the clinical symptoms of BPH patients， improving their quality of life， reducing the volume of the prostate， and decreasing postoperative complications. In addition， the external treatment methods of TCM， such as acupuncture therapy， moxibustion， hot water bathing， acupoint application， anal suppository， and enema therapy， are also widely used in clinical practice， demonstrating the diverse ways of TCM in treating BPH. TCM and western medicine complement each other's advantages in the treatment of BPH， thus enhancing the clinical efficacy and reducing the occurrence of long-term complications. This study reviewed the etiology， pathogenesis， and treatment progress of BPH with TCM in recent years， and summarized the current research status. From three aspects of producing high-quality clinical research， standardizing the clinical diagnosis and treatment of TCM， and combining cutting-edge research to explore the mechanism of TCM， it provided suggestions for clinical research on the treatment of BPH with TCM to promote the development and application of TCM in the treatment of this disease.
ABSTRACT
Objective: To study the therapeutic effect of Huoxue Tongluo Decoction (HXTLD) on erectile dysfunction caused by ischemic stroke and identify the mechanisms involved. Methods: Network pharmacology was used to predict the key active ingredients and targets of HXTLD. Surgical methods were used to create a rat model of ischemic stroke. The rats were then given a suspension of HXTLD by ig administration. Erectile function was evaluated by Apomorphine (APO) induction. Real-time fluorescence quantitative reverse transcription-polymerase chain reaction (Real-time PCR) and Western blotting were used to detect the expression of related mRNAs and proteins in rat penile corpus cavernous tissue and brain tissue. Hematoxylin & Eosin (HE) staining was used to investigate structural changes in the penile cavernous tissue. Results: Network pharmacology showed that tumor necrosis factor (TNF), nitric oxide synthase 3 (eNOS), and vascular endothelial growth factor (VEGF) were the key targets of HXTLD in the treatment of erectile dysfunction caused by ischemic stroke. Experimental studies showed that HXTLD improved erectile dysfunction caused by ischemic stroke. HE results showed that HXTLD improved the structure of the corpus cavernosa. HXTLD also inhibited the expression of TNF and VEGF proteins in penile tissue (P < 0.05) and enhanced the expression of eNOS protein in penile tissue (P < 0.05). Conclusion: HXTLD improved the erectile function of rats with erectile dysfunction caused by ischemic stroke by regulating the mRNA and protein levels of TNF, eNOS and VEGF.
