DCD WeChat ethical review had its necessity and superiority but problems and confusion as well. For instance, WeChat review time was urgent and limited;WeChat review discussed insufficiently even hard to car-ry out;the methods of WeChat review were limited;the authenticity of audit opinion was difficult to grasp;the re-view data privacy existed hidden danger;the review quality was difficult to guarantee;WeChat conference content file archive was difficult, and so on. As to this, the author put forward the following countermeasures:giving war-ranty on the ethical review time as far as possible;initiating the committee review by the referee and uploading the review information to WeChat group, then ethical reviewers expressing their opinions in real names to ensure data confidentiality and privacy protection; strengthening the ethics committee education for organ transplantation; im-proving the quality of the review committee members and moral cultivation;archiving the WeChat conference infor-mation.

Objective To observe the long dwell ultrafiltration volume after using 7.5% icodextrin in different peritoneal transport characteristics of peritoneal dialysis patients. Methods Subgroup analysis of a perspective multicenter randomized double blind and parallel control study was performed. Continuous ambulatory peritoneal dialysis (CAPD) patients were divided into high transport (H) group, high-average transport (HA) group, low-average transport (LA) group and low transport (L) group according to D/Pcr and Twardoski standard. Ultrafiltration volume of night long dwell dialysate was calculated before and after clinic trial for 2 weeks and 4 weeks to evaluate the different effect of transporters on ultrafiltration volume. Results A total of 201 CAPD patients were enrolled in the study, including 98 patients in icodextrin group (ICO group) and 103 patients in glucose group (GLU group). Male and female cases were 96 and 105 respectively. Age was (56.1±13.7) years old (range from 18 to 81). One hundred and ninety-eight patients finished peritoneal equilibrium test (PET), including 24 (12.1%) of H, 72(36.2%)of HA, 81(40.7%)of LA,and 21 (11.0%)of L. After follow-up for four weeks, the ultrafiltration volume was much higher than baseline in H, HA and LA groups. Also ultrafiltration volume in icodextrin group was much higher than that in glucose-based dialysate. Howerve, the increased volume was not significantly difference in L group. Ultrafiltration volume of icodextrin was positively correlated to D/Pcr (R2=0.1681,P<0.01), while ultratration volume of dextrose was negatively correlated to D/Pcr (R2=0.0949,P<0.01). Conclusion Compare to glucose-based dialysate (Dineal), 7.5% icodextrin dialysate (Extraneal) improves the ultrafiltration and peritoneal creatinine clearance of long dwell notabily in H, HA and LA group.

OBJECTIVETo explore the clinical effects of relaying reversed perforator flaps in repairing skin and soft tissue defects at distal end of finger and donor site.
METHODSSeventeen patients (17 fingers) with skin and soft tissue defects at distal end of finger were hospitalized from June 2011 to June 2013. The reversed digital artery perforator flap with branch of digital nerve was used to repair the defect. The first donor site was repaired by dorsal metacarpal artery perforator flap; the second donor site was closed by suturing. The area of skin defect at distal end of finger ranged from 2.0 cm x 1.5 cm to 3.0 cm x 2.0 cm, and the area of digital artery perforator flap and dorsal metacarpal artery perforator flap ranged from 2.2 cm x 1.5 cm to 3.6 cm x 2.5 cm and 2.5 cm x 2.0 cm to 4.2 cm x 3.0 cm, respectively.
RESULTSAll the 34 flaps survived completely. Cyanosis and partial necrosis of the epidermis appeared in 1 flap, which was healed after dressing change. All the patients were followed up for 1 to 18 months, with mean time of 8 months. The color, texture and appearance of flaps were satisfactory. There was no depression or breakdown in the first donor sites. Some linear scars appeared in the second donor sites, but they did not affect the general appearance. The donor sites at joint or tendon did not affect the joint activity after healing. The results of function evaluation of range of active movement of the fingers were excellent in 15 cases and good in 2 cases. The results of sensation of the flaps were S3 in 1 finger, S4 in 2 fingers, and S5 in 14 fingers. The distance of two-point discrimination of flaps ranged from 5 to 7 mm, with mean distance of 6 mm.
CONCLUSIONSRelaying reversed perforator flap, with reliable blood supply and both donor sites in the hand, can improve the appearance and function of the first donor site as well as repair skin and soft tissue defects at distal end of finger.
