Objective To explore the availability and safety of conducting low-pressure TURP assisted by a home-made cystometry and warning system.Methods 167 benign prostatic hyperplasia (BPH) patients admitted from Jan 2014 to Jan 2016 were randomly assigned into cystostomy group (group A) and non-cystostomy group (group B). In group A (n = 85), 42 patients (group A1) were performed percutaneous cystostomy + TURP, and 43 (group A2) were performed continuous flushing sheath TURP. In group B (n = 82), 42 patients (group B1) were received percutaneous cystostomy + TURP, and 40 (group B2) were received continuous lfushing sheath TURP. In group A, bladder pressure was monitored in real time with a cystometry and was monitored by bladder puncture using a home-made siphon, ensuring low bladder pressure throughout TURP. Serum Na+ levels were measured before and after operation in all four groups. The operation time, the intraoperative bleeding, the weight of resected prostates and the time before which urine turned clear were recorded. The IPSS, maximum lfow rate (Qmax), postvoid residual volume (PVR) and life quality score (QOL) were evaluated.Results While no significant differences were found between group A1 and A2, there were significant differences between group B1 and B2, indicating cystostomy group was safer than non-cystostomy group. When compared group A1 with B1, or group A2 with B2, it showed that the safe operation time to perform prostate tissue resection was longer in cystostomy group; the weight of the resected prostates was heavier; the time before which urine turned clear were shorter; and the IPSS improvement was better. These findings presented better therapeutic effects in cystostomy group than in non-cystostomy group.Conclusions This home-made cystometry and warning system could timely detect high bladder pressure state during TURP, making it possible to avoid of high pressure, ensuring low bladder pressure lfushing during the operation, lengthening the safe operation time, increasing tissue resection ratio, reducing transurethral resection syndrome, thus helping TURP to be safer.

Objective To evaluate the risk of locoregional recurrence ( LRR ) and role of radiotherapy for patients with estrogen receptor?negative and human epidermal growth factor receptor 2?overexpressed ( Rec?/HER?2+) locally advanced breast cancer ( LABC ) . Methods A retrospective analysis was performed on the clinical data of 294 patients with Rec?/HER?2+LABC from 1999 to 2011. All patients were treated with modified radical mastectomy ( MRM ) . Of them, 239 patients received postmastectomy radiotherapy and 55 patients did not. Locoregional recurrence?free survival ( LRRFS) and overall survival ( OS) , as well as LRR, were compared between the two groups. The Kaplan?Meier method was used to estimate survival and recurrence rates, and the log?rank test was used for survival difference analysis and univariate prognostic analysis. Multivariate prognostic analysis was performed using the Cox regression model. Results The 5?year sample size was 162. Fifty?six patients developed LRR. The 5?year LRRFS and OS rates were 79. 7% and 70. 0%, respectively. Postmastectomy radiotherapy significantly increased the 5?year LRRFS rate ( 85. 1% vs. 56. 0%, P=0. 000) , but did not significantly increase the 5?year OS rate ( 71. 3% vs. 64. 2%, P= 0. 441 ) . Multivariate analysis indicated that postmastectomy radiotherapy was the only independent prognostic factor associated with increased LRRFS ( RR=0. 303, 95% CI:0. 166?0. 554, P=0. 000). Conclusions Patients with Rec?/HER?2+ LABC treated with MRM alone appear to be at a significantly increased risk of LRR compared with those treated with MRM followed by radiotherapy.

China Modern Doctor 2015;(15):31-33,36
Objective To study levonorgestrel intrauterine system on insulin-like growth factor-1 (IGF-1) in endometri-um tissue for patients with endometrial polyps. Methods All 182 patients with endometrial polyps in our hospital from January 2010 to December 2011 were selected as research object, and randomly divided into control group(routine treatment group)94 cases and observation group(levonorgestrel intrauterine system in uterus group)88 cases. The IGF-1 expression of endometrial biopsy specimens during intraoperative and rechected after 6 months were measurd by im-munohistochemistry. Patients were followed up for 2 years to analyse endometrial polyp recurrence. Results The ex-pressions of IGF-1 decreased significant in endometrium tissue of observation group with operation. But there were no significant differences in control group. Followed up for 2 years, the endometrial polyp recurrence was 8.05% in control group and without recurrence in study group. Conclusion Levonorgestrel intrauterine system may be involved in the in-hibiting of the expression of IGF-1 then to induce the recurrence of endometrial polyps.

Objective To analyze the outcomes and the role of radiotherapy in breast cancer pa-tients with T1-T2 and one to three positive axillary nodes treated with modified radical mastectomy, and to investigate the prognostic factors for loco - regional recurrence in patients without radiotherapy . Methods Three hundred and seventy breast cancer patients with T1-T2 and one to three positive axillary lymph nodes treated with mastectomy and axillary dissection were retrospectively analyzed. Kaplan-Meier method was used to calculate the overall survival (OS) and loco-regional recurrence-free survival (LRFS) rates. The Logrank test was used for the comparison of the survival curves of patients with or without radiotherapy. Univariate analyses of potential prognostic variables for LRFS were performed. Results The 5-year OS and LRFS rates were 85.4% and 91%. Radiotherapy significantly improved the 5-year LRFS rate ( 100% vs. 89.5% ;x2 = 5.17, P=0.023). However, there was no significant difference in overall survival rate between patients with and without radiotherapy. In univariate analyses, T stage, the number of positive axillary nodes, C-erbB-2 and PR status were the significant predictive factors for LRFS. Conclusions For breast cancer pa-tients with T1-T2. and one to three positive axillary nodes, radiotherapy improves the LRFS, but not OS. T stage, the number of positive axillary nodes, C-erbB-2 and PR status are predictive factors for loco-regional recurrence in patients without radiotherapy.
