Objective To explore the correlation of MET status in patients with advanced prostatic acinar adenocarcinoma with the clinical pathological parameters and prognosis. Methods The specimen from 135 patients with advanced prostatic acinar adenocarcinoma was included. The expression of c-MET protein was detected via immunohistochemistry, and MET gene amplification was assessed by fluorescence in situ hybridization. The relationships of c-MET expression and gene amplification with clinicopathological features and prognosis were analyzed. Results The positive expression rate of c-MET was 52.60% (71/135). Compared with the c-MET expression in adjacent tissues, that in tumor tissues showed lower heterogeneous expression. Among the cases, 1.71% (2/117) exhibited MET gene polyploidy, but no gene amplification was detected. Positive c-MET expression was significantly correlated with high Gleason scores and grade groups (P=

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.

Objective:To systematically compare the safety and reliability of remodeling and reimplantation in aortic root valve preservation surgery for acute Stanford type A aortic dissection.Methods:We searched the databases of CNKI, VIP, Wanfang, CBM, Pubmed, EMBASE, Cochrane Central Register of Controlled Trials ( CENTRAL ) to find the clinical controlled research literature on acute type A aortic dissection remodeling and replantation. The relevant outcome indicators were analyzed by Review Manager 5.3 combined with Stata15.0 statistical software.Results:Seven studies involving 356 patients were included. Remodeling surgery versus replantation surgery. There was a higher incidence of postoperative grade Ⅱ or Ⅲ aortic regurgitation( OR=5.56, 95% CI: 1.89-16.41, P<0.05 ), higher 5-year reoperation rate ( OR=7.50, 95% CI: 2.11-26.65, P<0.05 ), shorter cardiopulmonary bypass time ( MD=-20.81, 95% CI: -35.08-6.54, P< 0.05 ), and longer aortic occlusion time ( MD=35.23, 95% CI: 21.21-49.26, P<0.05 ). The 30-day/in-hospital mortality( OR=1.09, 95% CI: 0.56-2.13, P>0.05) , postoperateive secondary thoracotomy for hemostasis( OR=2.91, 95% CI: 0.34-24.99, P>0.05), the rate of reoperation 1 year after surgery( OR=1.22, 95% CI: 0.20-7.56, P> 0.05) and 5-year mortality( OR=7.50, 95% CI: 2.11-26.65, P>0.05), were no significant difference between remodeling surgery group and replantation surgery group. Conclusion:Compared with replantation surgery, remodeling surgery in patients with acute type A aortic dissection has a higher incidence of grade Ⅱ or Ⅲ aortic insufficiency, a higher rate of reoperation 5 years after surgery, a shorter duration of cardiopulmonary bypass, and a longer duration of aortic occlusion. There were no statistically significant differences in postoperative hospitalization/30-day mortality, postoperative secondary thoracotomy, reoperation rate 1 year after surgery, and late mortality using remodeling and replantation techniques, which could be selected according to the actual situation of the aortic root and the experience of the surgeon.
