Objective To summarize the complications of the single-port transumbilical laparoscopic pyeloureteroplasty.Methods From August 2009 to December 2014, 162 surgical procedures were performed in our institute with the single-port transumbilical laparoscopic pyeloureteroplasty.Medical records of each procedure were retrospectively evaluated.139 patients were male and 23 female, aged from 1 month to 14 years and the median age of 2 years.127 patients were operated on the left side and 32 on the right side.3 patients were operated on the bilateral side.All children were supplemented with preoperative ultrasound, renal dynamic imaging and MRU to identify the ureteropelvic junction obstruction.Intraoperative and postoperative complications were graded according to the Satava and Clavien classifications respectively.Major complications were defined as Satava grade Ⅱ or higher, and Clavien grade Ⅲ or higher.Results There was no injury of vascular or visceral organs and no blood transfusion, and there was no serious intraoperative complications.One hundred and forty-three cases were followed up, and 23 cases (16.1％)presented with postoperative fever (＞ 38 ℃C) (Clavien Ⅰ), 2 cases (1.4％) with urinary extravasation diagnosed by perirenal fluid collection(Clavien Ⅰ).All these cases recovered after being given symptomatic treatment.7 cases (4.9％) presented with postoperative repeated urinary infection (Clavien Ⅱ).5 cases received postoperative reoperation due to the obstruction of the anastomic site (Clavien Ⅲ b), and 2 cases were under debridement as the greater omentum was drawn out along with the negative pressure drainage tube(Clavien Ⅲ a).In summary, the incidence of severe postoperative complications was 4.9％.Conclusions Though there existed some postoperative complications of the single-port transumbilical laparoscopic pyeloureteroplasty, the incidence of serious complications was low and the overall prognosis could be good.

Objective To investigate the indications and surgical approaches of full-thickness eyelid reconstruction with superficial temporal artery island flap and oral mucosa free grafting,and evaluate the safety and efficacy.Methods A total of 13 eyes of 13 patients with wide full-thickness eyelid defect were treated by the eyelid reconstruction with superficial temporal artery island flap and oral mucosa free grafting.The defect area was(33.67?8.35) mm?(16.44?4.45) mm and the size of island flap was(38.56?8.99)mm?(18.44?4.00)mm.Eight cases were treated with oral lip mucosa grafting,while the other 5 with hard plate muco-periosteal free grafting.Follow up was conducted for 6 to 24 months. Results The flaps were clinically viable in 10 cases and partially viable in 2.One was inviable for venous circumfluence failure,and a successful free skin grafting was conducted 3 months postoperation.All the grafted oral mucosa survived.Five cases underwent the second surgery to thin the island flap,among whom 3 were performed eyelid suspension with the frontal muscle.The survived flaps were similar to skin in colour,soft in nature,and could effectively protect the eyeballs. Conclusion The superficial temporal artery island flap along with oral mucosa free grafting works well in wide full-thickness eyelid reconstruction.

Objective To investigate the effect of infrasound on the growth of bone marrow mescenchymal stem cells (BMSCs) and seek the most reasonable duration for using infrasound. Methods The primary BMSCs were obtained from Sprague-Dawley rats through whole bone marrow adherent cultivation.The cells of passage 3 were divided into trial groups treated with infrasound for 10 min,30 min or 60 min,and control groups which were not treated with infrasound but exposed to air for the same durations.The vitality of cell proliferation was measured using the CCK8 method.Apoptosis and the cell cycle were analysed with flow cytometry (FACS). Results After cultivation for 72 h,the optical density (OD) values for BMSCs treated with infrasound for 10 min,30 min and 60 min were 1.480 ± 0.030,1.348 ± 0.030,1.493 ± 0.030 respectively and after 96 h they were 1.774 ± 0.030,1.731 ± 0.030 and 1.833 ± 0.030.All of which were significantly greater than in the control groups ( 1.479 ± 0.030,1.267 ±0.030 and 1.227 ± 0.030 after 72 h and 1.567 ± 0.030,1.563 ± 0.030 and 1.632 ± 0.030 after 96 h).With the extension of the treatment duration,the OD values of the BMSCs increased or increased after decreasing,and the OD value for BMSCs treated with infrasound for 60 min was the highest.The FACS results indicated no effect of infrasound on apoptosis of BMSCs when the treatment duration was 30 min,but that cell apoptosis could be inhibited when the treatment duration was 10 min or 60 min.The early phase apoptosis rates were 1.07％ ± 0.12％ and 0.97％ ±0.21％ in the trial groups treated for 10 min and 60 min respectively,and 1.43％ ± 0.06％ and 3.33％ ± 0.15％ in the respective control groups,a highly significant difference.The results of cell cycle analysis showed infrasound could disturb the cell division of BMSCs significantly when the treatment duration was less than 30 min,but there was no significant effect when the treatment duration was 60 min. Conclusions Infrasound can promote cell proliferation and disturb cell division,but it did not cause apoptosis of BMSCs.When the treatment duration was 60 min,cell proliferation improved steadily,the apoptosis rate decreased,and the cell cycle did not change.So 60 min is the most reasonable treatment duration for infrasound.

0.05). But the incidence of rehospitalization in combination group because of adverse cardiovascular events wasn’t more two times than that of non-combination group (OR=2.07; 95% confidence interval ranged from 1.87 to 2.20). CONCLUSION: The results of study are similar to other studies of foreign countries. PPI can influent the anti-platelet effect of clopidogrel so as to increase the incidence of rehospitalization risk resulted from adverse cardiovascular events. Physicians should apply PPI with cautions.
