OBJECTIVETo explore the correlation of histologically proven prostatitis with the level of prostate specific antigen (PSA), prostate volume, PSA density (PSAD), international prostate symptom score (IPSS), maximum flow rate (Qmax) and post-void residual volume (PVR) in men with symptoms of benign prostate hyperplasia (BPH).

METHODSTotally 673 patients surgically treated for BPH were divided into Groups A and B in accordance with histological findings, the former including those with histological prostatitis, and the latter without it. Comparisons were made between the two groups in the PSA level, prostate volume, PSAD, IPSS, Qmax and PVR.

RESULTSThe PSA level, prostate volume, IPSS and PVR were significantly higher in Group A ([5.64 +/- 2.48] microg/L, [43.66 +/- 13.11] ml, 24.72 +/- 5.39 and [124.90 +/- 49.80] ml) than in B ([4.97 +/- 1.99] microg/L, [40.41 +/- 11.44] ml, 23.40 +/- 6.21 and [112.73 +/- 50.03] ml) (P<0.05), while Qmax markedly lower in the former ([6.94 +/- 3.23] ml/s) than in the latter ([7.75 +/- 3.52] ml/s) (P<0.05), but PSAD showed no statistically significant difference between the two groups (0.129 +/- 0.048 vs 0.123 +/- 0.034, P>0.05).

CONCLUSIONHistological prostatitis can significantly increase the PSA level, prostate volume, IPSS and PVR, and reduce the Qmax of the patient, but is not correlated with PSAD. It is an important factor influencing the clinical progression of BPH.

Objective: To confirm the impact of obstructive sleep apnea hypopnea syndrome (OSAHS) on perioperative and long-term outcome in patients with Stanford type A aortic dissection. Methods: From June 2010 to July 2017, the clinical data of 91 patients with Stanford type A aortic dissection were analyzed. Among them, 51 patients with OSAHS were included in the study group and 40 patients without OSAHS were included in the control group. After 36 months follow-up, all-cause death was regarded as the end event. The clinical baseline data, perioperative period and 36 months survival rate of the two groups were compared. Kanplan-Meier method was used to describe the 36 month survival curve of the two groups. Cox proportional risk model was used to evaluate the risk ratio (HR) and 95%CI of 36 month survival rate. Results: The mortality rate during hospitalization was 5.9% (3 cases) in the study group and 5.0% (2 cases) in the control group, and the difference was not statistically significant (χ~2=0.03, P>0.05). The actual follow-up was (36.2±1.5) months, 88 cases were followed up and 3 cases were lost. The all cause mortality rate of 36 months was 27.5% (14/51)in the study group and 10.0%(4/40) in the control group, the difference was statistically significant (χ~2=4.30, P<0.05).By Cox proportional risk model analysis, 36 months after operation, the study group was compared with the control group after adjusting for age, male, bicuspid of aortic valve, chronic obstructive pulmonary disease, anemia, preoperative pericardial tamponade, postoperative organ dysfunction, preoperative LVEF, emergency operation, Sun's operation, coronary artery bypass grafting, hypertension, cardiac arrhythmia, and advanced avulsion of distal aortic dissection The survival rate was lower, the difference was statistically significant (P<0.05).In addition to OSAHS, coronary artery bypass grafting and preoperative pericardial tamponade were also risk factors for the increase of 36 month mortality rate (HR=11.28,95%CI: 1.98-46.25, P=0.009; HR=9.08, 95%CI: 2.22-41.3, P=0.032). Conclusions: There was no significant difference in mortality during hospitalization in patients with Stanford A aortic dissection combined with OSAHS. The survival rate of 36 months after operation was lower than that of the control group.
