Objective To observe the clinical outcomes of modified posteromedial and posterolateral approaches for the treatment of posterior tibial plateau fractures.Methods Between January 2006 and October 2011,25 patients with posterior tibial plateau fracture were identified.They were 17 men and 8 women,aged from 22 to 76 years (average,46.4 years).According to the AO/OTA classification,there were 4 cases of type 41-B1,6 cases of type 41-B2 and 15 cases of type 41-B3.According to Luo's three-column classification,they were all posterior column fractures.Ten patients with posterolateral tibial plateau fracture were treated by the modified posterolateral approach and the other 15 patients with posteromedial tibial plateau fracture by the modified posteromedial approach.The posterior fractures were fixated with a buttress plate.The knee function was evaluated at the last follow-up by the The Hospital for Special Surgery (HSS) Score.Results All the 25 cases were followed up for a mean time of 13.2 months (from 10 to 24 months).By the radiological Rasmussen criteria for fracture reduction,the mean score immediately after surgery was 16.5 points (from 13 to 18 points),with 20 excellent cases,4 good cases and one fair case.All patients were pain-free with full range of motion.Radiologically,bone union was achieved in all cases after a mean time of 13.9 weeks (from 12 to 18 weeks).No surgery-related complications were found.The mean HSS score was 91 points(range,74 to 97 points) and the good to excellent rate was 100％ (17 excellent and 8 good cases) at the last follow-up.The average range of knee motion ranged from 0° to 125°.Conclusion In the treatment of posterior tibial plateau fractures,because the modified posteromedial and posterolateral approaches can result in excellent fracture reduction under direct visualization and allow for posterior buttress plating,soft tissues can be well preserved and good functional results can be expected.

Objective To evaluate the effect of wound experts′ intervention on the primary caregivers′ behavior of caring patients with pressure ulcers. Methods According to the principle of convenience sampling, 200 cases of patients with out-hospital pressure ulcers were collected in the hospital emergency department between December 2013 and December 2015. Each 100 cases were randomly divided into the intervention group and the control group according to odd even packet. Primary family caregivers in the intervention group were implemented the additional behavioral intervention by professional wound experts on the basis of the conventional education, while the control group only with conventional education. Primary caregivers′behavior score in the intervention group were compared in 1 month and 2 months. And the differences of recovery rate and incidence of pressure ulcers were compared between intervention group and control group. Results The recovery rate of pressure ulcers in intervention group was 59% (59/100) ,which was significantly higher than 32% (32/100) of the control group (χ2=14.690, P=0.000), and the incidence of pressure ulcers rate was 24% (24/100) in intervention group which was significantly lower than 39%(39/100) in the control group (χ2=5.214,P=0.022). Primary caregivers′behavior scores in the intervention group were (48.27±6.12) points after 1 month and (46.18± 4.44) points after 2 months, while those in the control group were (44.15 ± 4.33) points and (43.33 ± 5.67) points, respectively, and the difference of behavior scores in different time-points were statistically significant (F=18.93, P < 0.01). Moreover, the difference of behavior scores was also statistically significant between intervention group and control group (F=5.512, P < 0.05). Conclusions Wound experts′ intervention on home primary caregivers can effectively help improve caregivers′ behavior, promote the healing of pressure ulcers, and reduce the occurrence of complications.

Lipoprotein lipase (LPL) is the rate-limiting enzyme for the hydrolysis of the triglyceride core of circulating triglyceride-rich lipoproteins.LPL can not only affect the lipoprotein level,but also play an important role in the development of atherosclerosis.LPL gene polymorphisms may affect LPL activity,and therefore have both pro-and anti-atherogenic effects.This article reviews the relationship between LPL gene polymorphism and atherosclerosis.
