RESUMEN
Ursolic acid (UA) is a naturally occurring pentacyclic triterpenoid widely found in fruits and vegetables. It has been reported that UA has anti-inflammatory effects. However, its efficacy and mechanism of action in the treatment of chronic prostatitis (CP) remain unclear. This study aimed to investigate the efficacy of UA treatment in CP and further explore the underlying mechanism. CP rat and pyroptosis cell models were established in vivo and in vitro, respectively. The efficacy of UA in inhibiting CP was evaluated via haematoxylin-eosin (HE) staining and measurement of inflammatory cytokines. RNA sequencing and molecular docking were used to predict the therapeutic targets of UA in CP. The expression of pyroptosis-related proteins was examined using various techniques, including immunohistochemistry, immunofluorescence, and flow cytometry. UA significantly ameliorated pathological damage and reduced the levels of proinflammatory cytokines in the CP model rats. RNA sequencing analysis and molecular docking suggested that NLRP3, Caspase-1, and GSDMD may be key targets. We also found that UA decreased ROS levels, alleviated oxidative stress, and inhibited p-NF-κB protein expression both in vivo and in vitro. UA improved pyroptosis morphology as indicated by electron microscope and inhibited the expression of the pyroptosis-related proteins NLRP3, Caspase-1, ASC, and GSDMD, reversed the levels of IL-1ß, IL-18, and lactate dehydrogenase in vivo and in vitro. UA can mitigate CP by regulating the NLRP3 inflammasome-mediated Caspase-1/GSDMD pathway. Therefore, UA may be a potential for the treatment of CP.

PURPOSE: To assess the role of atrial fibrillation (AF) on complicating inpatient outcomes of radical prostatectomy (RP). MATERIALS AND METHODS: We identified patients treated with RP during 2012-2014 within National Inpatient Sample (NIS) database. Length of stay, cost of hospitalization, and in-hospital complications were compared between patients with or without diagnosis of AF. Propensity score matching methods and multivariable regression analysis were used to adjust for potential confounders and a trend analysis was conducted. RESULTS: Patients with AF had a significantly longer hospital stay (coefficient 0.19, 95% CI 0.09-0.29, P < 0.001) and higher cost (coefficient 0.10, 95% CI 0.06-0.15, P < 0.001). Post-operative cardiac complications were significantly higher for patients with AF (OR 16.38, 95% CI 7.72-34.74, P < 0.001), while no differences were found in other complications between the two groups. Similar results were shown in propensity score matching methods. The cardiac complications after laparoscopic RP (OR: 37.71, 95% CI 1.85-768.73, P = 0.018) and open RP (OR: 16.78, 95% CI 1.41-199.51, P = 0.026) were significantly higher than robot-assisted RP (RARP) in patients with AF. The results of trend study indicated that postoperative cardiac complication rates showed a trend of decreasing year by year while the prevalence of AF was rising. CONCLUSIONS: Perioperative AF is associated with increased cardiac complications, longer hospital stay and higher cost in PCa patients undergoing RP. RARP may be a preferred choice for patients with AF. Attention should be paid to this special patient population. Reasonable pre-operative risk stratification and standardized management should be done to decrease perioperative complications.

OBJECTIVE: To explore the possible mechanism of Huanshao Capsules (HSC) protecting the reproductive function in rats with ornidazole-induced asthenozoospermia (AZS). METHODS: Forty SD male rats were randomly divided into four groups of equal number, blank control, AZS model control, HSC and L-carnitine (LC) intervention. The AZS model was established in the latter three groups of rats by intragastrical administration of ornidazole at 400 mg/kg/d for 28 days, and meanwhile the animals in the HSC and LC groups were treated by gavage of HSC at 0.31 g/kg/d and LC at 100 mg/kg/d, respectively. Then, all the rats were killed for examination of the LC content, sperm concentration, sperm motility and expression of OCTN2 mRNA in the epididymis and observation of the histopathological changes in the testis tissue. RESULTS: Compared with the AZS model controls, the rats in the HSC and LC groups showed significantly increased LC content (2 880.3 vs 6 366.5 and 6 934.7 mg/L, P < 0.01), sperm concentration (ï¼»34.58 ± 10.25ï¼½ vs ï¼»46.19 ± 14.23ï¼½ and ï¼»42.25 ± 6.11ï¼½ ×106/ml, P < 0.01), sperm motility (ï¼»42.59 ± 7.54ï¼½% vs ï¼»61.34 ± 7.98ï¼½% and ï¼»61.34 ± 7.98ï¼½%, P < 0.01) and expression of OCTN2 mRNA in the epididymis (26.07% vs 27.26% and 27.15%, P < 0.01). The animals of the HSC group exhibited a higher comparability than those of the LC group to the blank controls in the morphology, arrangement and activity of spermatogenic cells. CONCLUSIONS: HSC can protect the reproductive function and improve sperm concentration and motility in the model rats with ornidazole-induced AZS, which may be associated with its abilities of up-regulating the expression of OCTN2 mRNA and increasing the LC content in the epididymis.

OBJECTIVE: To evaluate the effect and safety of Qianlieshutong Capsules (QC) in the treatment of BPH. METHODS: We searched 10 Chinese and English databases up to July 2019 for randomized controlled trials (RCT) on treatment of BPH with QC followed by a meta-analysis on the included articles using Cochrane Handbook 5.1.0 and Revman5.3 software. RESULTS: A total of 18 RCTs involving 1 802 cases of BPH were included out of the 175 articles identified. The baseline data from the RCTs were all comparable. Compared with the controls, the patients treated with QC showed a significantly higher rate of clinical effectiveness and better improvement in IPSS as well as in the maximum urinary flow rate (Qmax), postvoid residual urine (PVR) and prostate volume after 3 months of medication. No serious adverse drug events or reactions were reported. CONCLUSIONS: The existing data and methodology indicate the efficacy and safety of Qianlieshutong Capsules in the treatment of BPH, which, however, has to be further verified by more well-designed large-sample multi-center high-quality randomized controlled trials.

OBJECTIVE: To observe the effificacy and safety of Qiaoshao Formula (, QSF) on patients with lifelong premature ejaculation (LPE) of Gan (Liver) depression and Shen (Kidney) defificiency syndrome. METHODS: A total of 60 LPE patients were randomly divided into treatment (QSF) and control (dapoxetine) groups. The treatment group received QSF twice a day and the control group received dapoxetine 1 to 2 h prior to planned sexual intercourse for 4 weeks. The outcomes included intra-vaginal ejaculation latency time (IELT), premature ejaculation diagnostic tool (PEDT), clinical global impression of change (CGIC), scores of Chinese medicine symptoms (CMSS), sex life satisfaction (SLS) and adverse events (AEs). RESULTS: In the treated group, the median IELT was 3 min vs. 1.5 min before and after treatment (P<0.05). PEDT in the treated group was reduced to 11.76±1.68 from 15.83±2.30 after treatment (P<0.05). Besides, patient's SLS was improved from 1.30±0.05 to 6.30±0.04 (P<0.05), and spouse's SLS was increased from 1.30±0.to 6.10±0.06 (P<0.05); CMSS was decrease from 14.86±3.02 to 9.62±2.87 (P<0.05). In addition, no significant AE was observed in both groups. CONCLUSION: QSF may be effective and safe on LPE patients with Gan depression and Shen defificiency syndrome.
