Objective To assess the urinary continence at a follow-up of 1 year after radical retro-pubic prostatectomy. Methods By using subjective (questionnaire) and objective (pad-test) methods, 165 consecutive prostate cancer patients were followed up at least 1 year. With the purpose to improve post-operative continence, surgical techniques such as preservation of external striated sphincter, preservation of bladder neck and pre-prostate sphincter (PPS), and nerve-sparing technique have been carried out.Analyses were also made in comparison by age. Results A post-operative incontinence rate of 0.7% was found in the sphincter preserving group and 5.3% in the sphincter repairing group. Patients aged 50~60 revealed a continence rate of 60% when the urethral catheter was removed, whereas 82% in the 60~70 group.After 3 months of follow-up, the continence rate of both age groups tended to be similar. Conclusions Surgical improvement and patients' age are important factors in post-operative continence after radical retro-pubic prostatectomy. The preservation of external urethral sphincter helps improve continence rate. Younger patients tend to regain to continence in a shorter period while the elders longer.

Objective To analyze the displacement of titanium clips for tumor bed localization after breast-conserving surgery for breast cancer and its influential factors.Methods A retrospective analysis was performed on the cone-beam computed tomography (CT) images of 14 patients with breast cancer who received radiotherapy after breast-conserving surgery from April to October,2016.The relative position of the chest wall and the errors of the titanium clips in radiotherapy were measured.A Pearson correlation analysis was used to analyze the correlation of the displacement of titanium clips with the relative position of titanium clips,the breast volume,the vertical distance between the titanium clips and the tangential line of the chest wall,and the maximum thickness of the breast.Results The system errors of the chest wall in left-right,superior-inferior,and anterior-posterior directions were 4.42,3.44,and 5.13 mm,respectively,and the random errors were 3.55,3.07,and 4.54 mm,respectively.The titanium clips had a large displacement relative to the chest wall,mainly in the left-right direction.The maximum system error was 4.39 mm and the random error was 2.42 mm.The displacement of titanium clips was not significantly correlated with the breast volume and the maximum thickness of the breast (P>0.05).However,the relative position of titanium clips in superior-inferior direction was significantly correlated with the displacement of the lowest,the most lateral,the most anterior,and the most posterior titanium clips (P<0.05).As to the uppermost clips,there was a significant difference in displacement between the clips close to the chest wall and the clips far from the chest wall (P=0.02).Conclusions Due to large setup error and displacement of titanium clips during radiotherapy,simultaneous integrated boost is not suitable for patients with breast cancer who are immobilized by vacuum cushion and received radiotherapy.The unstable immobilization may be the major influential factor for the displacement of titanium clips.

Objective To investigate the effects of recombinant human fibronectin fragment (RetroNectin) combined with anti-CD3 monoclonal antibody (CD3Ab) on the proliferation and cytotoxicity of cytokine-induced killer cells (CIK) from acute leukemia (AL). Methods Mononuclear cells (MNCs) were isolated from peripheral blood of complete remission AL pa-tients. The MNCs were cultured in vitro by precoating with RetroNectin (RN group), CD3Ab (CD3Ab group), RetroNectin com-bined with CD3Ab (RN+CD3Ab group) and traditional method (control group) to generate CIK. The changes of growth rate, characterization, cytotoxicity and apoptosis of CIK were determined between groups. Results The amplification of CIK was higher in experimental group than that of control group, and the amplification of CIK was higher in group RN+CD3Ab than that of in group RN and group CD3Ab (P<0.05). The expression of CD25 positive cells was higher in group RN and group RN+CD3Ab than that of group CD3Ab and control group (P<0.05).The percentage of G1 stage cells was lower in group RN and group RN+CD3Ab than that of group CD3Ab and control group. The percentage of S stage cells was higher in group RN and group RN+CD3Ab than that of group CD3Ab and control group (P<0.05). The cytotoxicity was higher in group RN and group RN+CD3Ab than that of group CD3Ab and control group (P<0.05) at the E/T scope 40∶1.The percentage of apoptotic cells was lower in group RN and group RN+CD3Ab than that of group CD3Ab and control group (P < 0.05). Conclusion These in vitro studies suggest that a higher activity of immune cells could be obtained by CIK cells cultured by precoating Ret-roNectin and CD3Ab.

OBJECTIVE:
To evaluate decision regret among patients receiving penile girth enhancement with acellular dermal matrix (PGE with ADM) and to investigate the potential indicators for decisional regret so as to facilitate the decision-making process for this special group.
METHODS:
In the study, 78 patients receiving PGE with ADM from Jun. 2016 to Jan. 2019 at Peking University People's Hospital and cooperative hospitals were eligible. Penile girth was taken by only one surgeon 1 week before surgery. Hospital anxiety and depression scale (HAD), international index of erectile function (IIEF) and a 10 cm long visual analogue scale named visualized penile image (VPI) were applied to measure psychological burden, erectile function and satisfaction with penile image respectively at the same time. All the patients were followed up for 3 months. Decision regret scale (DRS) was adopted for measuring decisional regret. Multivariate analysis of variance was applied to investigate the potential indicators for regret. Data analysis process was conducted with SPSS (version 24.0; SPSS, Chicago, IL, USA).
RESULTS:
Mean penile girth recorded before intervention was (8.29±0.30) cm and increased to (9.46±0.29) cm post surgery (t=76.28, P < 0.01). As for both subscales of HAD measuring psychological burden, a signi-ficant reduction in the mean score was seen, that is, 2.8±1.3 (t=19.28, P < 0.05) for anxiety and 3.0±1.2 (t=20.67, P < 0.05) for depression, respectively. The average score of VPI increased by 3.7±1.1 (t=30.63, P < 0.05). There was no significant change in the average score of IIEF measuring erectile satisfaction (t=1.60, P=0.11). Twenty-nine (38.2%) patients expressed regret to some degree, and the mean DRS score was 23.4±14.8. The scores of DRS correlated negatively with scores of visualized penis image (r=-0.348, P < 0.01), and positively with scores of anxiety (r=0.760, P < 0.01) and depression subscale (r=0.471, P < 0.01). The scores of DRS was irrelevant to those of IIEF (r=0.02, P=0.867). The patients with high annual income (> 120 000 yuan) and education level above undergraduate were more prone to experience decision regret after intervention (P < 0.01).
CONCLUSION
PGE with ADM did augment penile girth and lower psychological burden, the regret rate of which was acceptably low among the patients. High income and good education might indicate more post-operative regret. Additional decision-making aids should be offered to patients with high income and education level above high school.
