| 1 | What operation for recurrent rectal prolapse after previous Delorme's procedure? A practical reality显示文摘AIM: To report our experience with perineal repair(Delorme's procedure) of rectal prolapse with particular focus on treatment of the recurrence.METHODS: Clinical records of 40 patients who underwent Delorme's procedure between 2003 and 2014 were reviewed to obtain the following data: Gender; duration of symptoms, length of prolapse, operation time, ASA grade, length of post-operative stay, procedure-related complications, development and treatment of recurrent prolapse. Analysis of post-operative complications, rate and time of recurrence and factors influencing the choice of the procedure for recurrent disease was conducted. Continuous variables were expressed as the median with interquartile range(IQR). Statistical analysis was carried out using the Fisher exact test.RESULTS: Median age at the time of surgery was 76 years(IQR: 71-81.5) and there were 38 females and 2 males. The median duration of symptoms was 6 mo(IQR: 3.5-12) and majority of patients presented electively whereas four patients presented in the emergency department with irreducible rectal prolapse. The median length of prolapse was 5 cm(IQR: 5-7), median operative time was 100 min(IQR: 85-120) and median post-operative stay was 4 d(IQR: 3-6). Approximately16% of the patients suffered minor complications such as- urinary retention, delayed defaecation and infected haematoma. One patient died constituting postoperative mortality of 2.5%. Median follow-up was 6.5 mo(IQR: 2.15-16). Overall recurrence rate was 28%(n = 12). Recurrence rate for patients undergoing an urgent Delorme's procedure who presented as an emergency was higher(75.0%) compared to those treated electively(20.5%), P value 0.034. Median time interval from surgery to the development of recurrence was 16 mo(IQR: 5-30). There were three patients who developed an early recurrence, within two weeks of the initial procedure. The management of the recurrent prolapse was as follows: No further intervention(n = 1), repeat Delorme's procedure(n = 3), Altemeier's procedure(n = 5) and rectopexy with faecal diversion(n = 3). One patient was lost during follow up.CONCLUSION: Delorme's procedure is a suitable treatment for rectal prolapse due to low morbidity and mortality and acceptable rate of recurrence. The management of the recurrent rectal prolapse is often restricted to the pelvic approach by the same patientrelated factors that influenced the choice of the initial operation, i.e., Delorme's procedure. Early recurrence developing within days or weeks often represents a technical failure and may require abdominal rectopexy with faecal diversion. | Muhammad A Javed Faryal G Afridi Dmitri Y Artioukh | 2016 | World Journal of Gastrointestinal Surgery2016，8，7： | 4 |
| 2 | Comparative analysis of the effectiveness of abiraterone before and after docetaxel in patients with metastatic castration-resistant prostate cancer显示文摘AIM: To study the efficacy and safety of abiraterone in patients with and without prior chemotherapy.METHODS: The databases including Pub Med and abstracts presented at the American Society of Clinical Oncology meetings up to April 2014 were systematically searched. Eligible studies included randomized controlled trials(RCTs) in which abiraterone plus prednisone was compared to placebo plus prednisone in metastatic castration-resistant prostate cancer(CRPC) patients. The summary incidence, relative risk, hazard ratio and 95%CI were calculated using random or fixed-effects models. Heterogeneity test was performed to test between-study differences in efficacy and toxicity.RESULTS: A total of two phase III RCTs were included in our analysis, with metastatic CPRC patients before(n = 1088) and after chemotherapy(n = 1195). Prior chemotherapy did not significantly alter the effect of abiraterone on overall survival(P = 0.92) and prostatespecific antigen(PSA) progression-free survival(P = 0.13), but reduced its effect on radiographic-prog-ression-free survival(P = 0.04), objective response rate(P < 0.001), and PSA response rate(P < 0.001). Prior chemotherapy significantly increased the specific risk of fluid retention and edema(P < 0.001) and hypokalemia(P < 0.001), but decreased the risk of all-grade hypertension(P < 0.001) attributable to abiraterone. There was no significant difference of cardiac disorders associated with abiraterone between the two settings(P = 0.58). CONCLUSION: Prior chemotherapy may reduce the effectiveness of abiraterone in patients with metastatic CRPC. | Raji Shameem Muhammad Saad Hamid Kevin Y Xu Shenhong Wu | 2015 | World Journal of Clinical Oncology2015，6，4： | 3 |
| 3 | Mimicking unfolding motion of a beetle hind wing显示文摘This paper presents an experimental research aiming to realize an artificial hind wing that can mimic the wing unfolding motion of Allomyrina dichotoma, an insect in coleopteran order. Based on the understanding of working principles of beetle wing folding/unfolding mechanisms, the hind wing unfolding motion is mimicked by a combination of creative ideas and state-of-art artificial muscle actuator. In this work, we devise two types of artificial wings and the successfully demonstrate that they can be unfolded by actuation of shape memory alloy wires to provide actuation force at the wing base and along the leading edge vein. The folding/unfolding mechanisms may provide an insight for portable nano/micro air vehicles with morphing wings. | MUHAMMAD Azhar PARK Hoon C HWANG Do Y BYUN Doyoung GOO Nam S | 2009 | Chinese Science Bulletin2009，54，14： | 3 |

| 7 | Revascularization strategies for patients with myocardial infarction and multi-vessel disease: A critical appraisal of the current evidence显示文摘Approximately half of patients presenting with myocardial infarction are found to have non-infarct related multi-vessel severe coronary artery disease. Various observational studies and randomized controlled trials have been conducted to assess if revascularization of non-infarct related artery is associated with better clinical outcomes. In this review, the authors discuss the various revascularization strategies in patients with multi-vessel disease who present with myocardial infarction. | Muhammad O Zaman Mohammad K Mojadidi Islam Y Elgendy | 2019 | Journal of Geriatric Cardiology2019，16，9： | 1 |
