BACKGROUND:The tourniquet is usualy fuly used or bilateraly used in partial time during bilateral total knee arthroplasty. However, very few people try to use it on one side and on the other side in partial time.
OBJECTIVE:To investigate the effective strategy of using a tourniquet in simultaneous bilateral total knee arthroplasty.
METHODS:80 patients (160 knees) with severe osteoarthritis who underwent simultaneous bilateral total knee arthroplasty in the Department of Orthopedics, Chinese PLA Medical School from January to December 2013 were divided into two groups according to the different tourniquet strategies. In test group (n=40), left knees did not receive tourniquet, and right knees received tourniquet in partial time. In control group (n=40), al knees received tourniquet in the whole time. The perioperative and postoperative blood loss, 3-day postoperative thigh sweling rate and pain visual analog scale, 3-week and 1-year postoperative Knee Society Score were recorded in both groups.
RESULTS AND CONCLUSION:There were no statisticaly significant differences between two groups in perioperative total blood loss (P > 0.05). However, postoperative blood loss in test group was less than that in control group (P < 0.05). The visual analog scale scores were significantly lower in the test group than in the control group at 3 days after surgery (P < 0.05). Visual analog scale scores on the left side were lower than on the right side in the test group at 3 days post surgery (P < 0.05). Bilateral thigh sweling rate was significantly lower in the test group than in the control group at 3 days after surgery (P < 0.05). The thigh sweling rate was lower on the left side than on the right side in the test group at 3 days after surgery (P < 0.05). Knee Society Score was higher in the test group than in the control group in the early stage, and no significant difference in long-term Knee Society Score was detected (P > 0.05). These findings verify that taking the strategy that the first knee without tourniquet and the second knee with part time tourniquet technique in simultaneous bilateral total knee arthroplasty wil aleviate pain and sweling after operation and promote early functional rehabilitation without increasing the perioperative total blood loss.

Objective:To investigate the effect of silver diamine fluoride(SDF)on the bonding strength between dentine and glass ion-omer cement(GIC).Methods:1 2 extracted sound molars were prepared into dintine samples and distributed into sound dentine group and demineralized dentine group.According to the treatment methods,the samples in each group were respectively divided into 3 sub-groups:A(control group),B[coated with 38% Ag(NH3 )F2 ]and C(SDF treatment with additional lighting-curing)(n =20).Then a hand-mixed conventional glass ionomer cement Fuji IX was placed on the dentine surface.After 24 h,micro tensile bond strength test and scanning electron microscope (SEM)analysis were conducted.Results:The bonding strength of demineralized dentine was higher than that of sound dentine(P <0.01 ).SDF with additional lighting-curing treated dentine showed a higer bonding strength value than only SDF treated dentin(P <0.01 ).Conclusion:SDF may improve the bonding between dentine and GIC.

Objective To establish a calculation software to determine paternity index(PI) in parentage testing and likelihood ratio (LR) in individual recognition.Methods Based on relevant industry standards and literature, using Visual Basic 6.0 to write the program.Results We successfully developed the calculation software for paternity index (PI) in parentage testing and likelihood ratio (LR) in individual recognition.Conclusion The calculation software can help staff to improve the calculation efifciency, and serve the forensic evidence.
