Efficacy and safety of LY01005 versus goserelin implant in Chinese patients with prostate cancer: A multicenter, randomized, open-label, phase III, non-inferiority trial / 中华医学杂志(英文版)

BACKGROUND@#LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.@*METHODS@#We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.@*RESULTS@#On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).@*CONCLUSION@#LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT04563936.

The application potential of a modified wireless intelligent capsule cystoscope for dynamic detection of porcine bladder mucosa / 中华泌尿外科杂志

Objective:To develop an improved wireless intelligent capsule cystoscope (WCE)for dynamic detection of bladder mucosa in a pig model.Methods:The WCE was introduced into a healthy experimental pig that under general anesthesia via urethra by applying an improved device. Multi-angle images of the bladder mucosa were then obtained by controlling the position of capsule cystoscope with an external magnetic field system. The shutter speed of the WCE was 2.5 fps and was automatically converted to 1.5 fps 30 minutes after initiation. The Vue software was utilized to download the shoot pictures which were former received by a computer via wireless transmission. The pig was roused and sent to the pigpen, without limitations in moving. The improved WCE was connected with a 2 cm thread. 12 hours later, the dilated sheath was inserted again, and the capsule was removed by a foreign body forceps under observation of a ureteroscopy.Results:The WCE was successfully placed and removed from the pig's bladder with the application of the improved devices. Over 20 thousand images that with 60K pixels of bladder mucosa were captured by the WCE at various angles within 12 hours, which revealed the process of urine filling and excreting in a time-dependent way. No notable adverse effects (bleeding, urinary tract injury, etc) were noted during the process of cystoscope placement, image acquisition, transmission, and removal.Conclusion:This study developed a novel WCE that could dynamically, intelligently and accurately monitor all aspects of the pig bladder mucosa, and has preferable application prospect.

Objective:To investigate the value of combined detection of serum neurogranin (NG) and hypoxia-inducible factor-1α (HIF-1α) in patients with severe craniocerebral trauma.Methods:Ninety-seven patients with severe craniocerebral trauma from June 2018 to March 2020 in Jinshan Branch of Shanghai Sixth People′s Hospital were selected. According to the Glasgow outcome score (GOS), 97 patients were divided into good prognosis group (GOS>3 scores, 46 cases) and poor prognosis group (GOS ≤ 3 scores, 51 cases). The NG, HIF-1α, Glasgow coma score (GCS), acute physiology and chronic health status score Ⅱ (APACHE Ⅱ) were compared between 2 groups. The independent risk factors of prognosis in patients with severe craniocerebral trauma were analyzed by multivariate Logistic regression analysis. The diagnostic efficacy of NG and HIF-1α on poor prognosis in patients with severe craniocerebral trauma was analyzed by receiver operating characteristic (ROC) curve. The correlation between serum NG, HIF-1α and APACHE Ⅱ in patients with severe craniocerebral trauma was analyzed by Pearson analysis.Results:The GCS in good prognosis group was significantly higher than that in poor prognosis group: (6.50 ± 1.74) scores vs. (4.76 ± 0.78) scores, the NG, HIF-1α and APACHE Ⅱwere significantly lower than those in poor prognosis group: (696.98 ± 158.96) ng/L vs. (875.92 ± 188.52) ng/L, (34.72 ± 13.98) μg/L vs. (51.29 ± 14.17) μg/L and (15.69 ± 3.45) scores vs. (22.58 ± 6.45) scores, and there were statistical differences ( P<0.01). Multivariate Logistic regression analysis result showed that the NG, HIF-1α, APACHEⅡ, GCS and type of craniocerebral trauma were independent risk factors on the prognosis in patients with severe craniocerebral trauma ( P<0.05 or<0.01). ROC curve analysis result showed that the AUC of NG and HIF-1αNG and HIF-1α combined detection to assess the poor prognosis in patients with severe craniocerebral trauma was significantly higher than NG and HIF-1α alone detection (0.873 vs. 0.772 and 0.821, Z = 2.276 and 1.949, P<0.05). Pearson correlation analysis result showed that APACHE Ⅱ was positive correlation with serum NG and HIF-1α in severe craniocerebral trauma patients with poor or good prognosis ( r = 0.852 and 0.889, P<0.01; r = 0.717 and 0.851, P<0.01). Conclusions:The combined detection of serum NG and HIF-1α can be used as an evaluation index for the prognosis in patients with severe craniocerebral trauma, which helps to determine the severity of craniocerebral trauma and has great value for clinical diagnosis and treatment.

Six-month angiographic and one-year clinical outcomes of polymer free paclitaxel-eluting stent in patients with ST-segment elevation myocardial infarction: a comparison with permanent polymer sirolimus-eluting stent / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Since permanent polymer is implicated in adverse events associated with delayed vessel healing after drug eluting stents (DES) implantation, great efforts have been made to develop more biocompatible DES with biodegradable polymer or without polymer. The present study aimed to evaluate the safety and efficacy of polymer free paclitaxel-eluting stents (PF-PES) in comparison with permanent polymer sirolimus-eluting stents (PP-SES) in patients with acute ST-segment elevation myocardial infarction (STEMI).</p><p><b>METHODS</b>Patients with STEMI were randomly assigned to receive PP-SES (n = 55), and PF-PES (n = 50). The 6-month angiographic and 1-year clinical outcomes were compared between the two groups. Target lesion failure (TLF) was defined as the composite of cardiac death, recurrent nonfatal myocardial infarction (Re-MI), or target lesion revascularization (TLR).</p><p><b>RESULTS</b>Follow-up angiography at six months was performed in 72.7% of the PP-SES group and 70.0% of the PF-PES group (P = 0.757). The two groups had comparable angiographic outcomes including minimal luminal diameter, diameter stenosis, late loss and binary restenosis. All patients were clinically followed up to one year. The two groups had similar clinical outcomes with relatively low rates of target lesion failure (10.9% PP-SES vs. 12.0% PF-PES, P = 0.861) and definite or probable stent thrombosis (1.8% PP-SES vs. 2.0% PF-PES, P = 1.000) at one year.</p><p><b>CONCLUSIONS</b>The present study suggests that the safety and efficacy of PF-PES in the setting of STEMI are comparable to PP-SES. Further randomized trials with larger study populations are needed to get definite conclusions.</p>

Evaluation of the effectiveness of cough test during tension-free vaginal tape procedure in preventing post-operative voiding dysfunction / 中华泌尿外科杂志

Objective To evaluate the value of cough test in the tension-free vaginal tape (TVT)procedure.Methods A cohort of 85 women with stress urinary incontinence underwent the TVT procedure with cough test (n =41) or without cough test (n =44).Patients in cough test group were performed according to the Ulmsten’s method strictly,with the stress of tape adjusted in light of cough test; whereas in other 44 operations,the tape was placed on the urethral tract without stress,and no cough test was performed.The urine catheter was removed after 48 hours postoperatively and follow-up evaluation was carried out at 12 month postoperatively.Results TVT procedure was carried out successfully in all patients by a single experienced surgeon.Four cases of urinary retention and 5 cases of voiding difficulty were observed in the cough test group.However,urinary retention or voiding difficulty was not detected in the nun-cough test group.Based on the twelve-month follow-up results,the cure rate was 92.6％ (38/41) in the cough test group and 93.1％ (41/44) in the non-cough test group.Flow-pressure study indicated that 11 cases in cough test group were in the obstruction zone,while only 3 cases in the obstruction zone were detected in the non-cough test group.Conclusions TVT is a safe as well as effective minimally invasive surgical procedure to treat female stress urinary incontinence.However,Adjusting stress of tape in accordance with cough test during the TVT may potentially increase the incidence of urinary dysfunction postoperatively.Therefore,no convincing evidence was gained to support the efficacy of cough test during TVT in terms of preventing postoperative voiding dysfunction.
