BACKGROUND:Valgus-varus constrained polyethylene insert is selected in strict accordance with the principle of“to obtain reliable stability using minimum restriction”. The stability of the prosthesis is elevated, but the restriction is not increased.
OBJECTIVE:To retrospectively analyze the application experience of constrained polyethylene insert in valgus and varus instability of primary total knee arthroplasty for older patients and to summarize the indications and clinical effects of this kind of implements.
METHODS:From March 2010 to March 2012, a total of 70 patients combined valgus and varus malfomation who accepted primary total knee arthroplasty were enrol ed in this study, including 56 varus patients (averagely 15°-30°) and 14 valgus patients (averagely 10°-20°). Constrained polyethylene insert was performed in 23 patients (25 knees) who stil had remaining unilateral valgus or varus<6 mm (18 patients were varus instability and 7 patients were valgus instability) when finished operation of standard osteotomy and soft tissue balancing. The bone cement knee prostheses in 23 cases were purchased from Smith&Nephew. The stem implant was not used in al cases. Cement or autografts were used in 11 valgus knees to fil the bone defects.
RESULTS AND CONCLUSION:Patients were fol owed up for 2 years on average (18-42 mouths). The knee pain symptoms of al cases disappeared. The joint stability was obviously improved. The lower limb power lines were correct. The Knee Society Score scores were improved from an average of 39.4 points preoperation to an average of 88.5 points postoperation. Al cases did not need the protection of knee braces. The maximum degree of flexion was 110°(96°-130°). The satisfaction degree of 36-Item Short Form Health Survey was 98%. No dislocation or infection happened. Results indicated that constrained polyethylene insert could be applied in the cases of less than 6 mm valgus and varus instability when finished operation of standard osteotomy and soft tissue balancing in total knee arthroplasty for older patients. This kind of implements can preserve bone mass, simplify operational process and have good clinical outcome in a short period.

OBJECTIVETo evaluate the protective effects of punicosides on alcohol induced acute liver injury in mice and its possible mechanisms as well.
METHODThe 60 mice were randomly divided into normal control, model group, three dose groups of punicosides with low, medium and high, then there is silibinin group. Three dose groups of punicosides and silibinin were given in advance by gavage for 4 weeks, then the mouse model of alcoholic acute liver injury was established. The serum levels of ALT, AST and TG were determined, and the mice were killed to calculate somatic index of liver, thymus as well as spleen. MDA, SOD, GSH-Px and GSH-ST were detected in the liver homogenate. Histopathological changes of the liver were observed by HE staining. The expression of MCP-1 and NF-kappaB in the liver tissues were detected by immunohistochemistry.
RESULTMid and high dose of punicosides reduced the liver index in mice significantly, improved liver steatosis, decreased the level of ALT, AST and TG in serum and the content of MDA in liver homogenate, furthermore the two dose groups increased the activity of SOD, GSH-Px and GSH-ST, inhibited the expression of MCP-1 and NF-kappaB in liver tissue.
CONCLUSIONPunicosides can protect the acute liver damage induced by alcohol.

OBJECTIVETo explore the relationship of bone cement distribution and the puncture angle in the treatment of thoracolumbar compression fractures with unilateral percutaneous kyphoplasty (PKP).
METHODSThe clinical data of 37 patients with thoracolumbar osteoporotic compression fractures underwent PKP between January 2013 to March 2014 were retrospectively analyzed, all punctures were performed unilaterally. There were 6 males, aged from 65 to 78 years old with an average of (71.83 ± 6.15) years; and 31 females, aged from 57 to 89 years old with an average of (71.06 ± 7.89) years. Imaging data were analyzed and puncture angle and puncture point were measured before operation. According to the measured data, the puncture were performeds during the operation. Distribution area of bone cement were calculated by X-rays data after operation. The effect of bone cement distribution on suitable puncture angle was analyzed; VAS score was used to evaluate the clinical effects.
RESULTSThe puncture angle of thoracic vertebrae in T8-T12 was from 28° to 33° with an average 30.4°; and the puncture angle of lumbar vertebrae in L1-L5 was from 28° to 35° with an average of 31.3°. Postoperative X-rays showed the area ratios of bilateral bone cement was 0.97 ± 0.15. Bilateral diffuse area were basic equal. Postoperative VAS score decreased significantly (1.89 ± 1.29 vs 7.03 ± 1.42).
CONCLUSIONThrough measure imaging data before operation with PKP,the puncture point and entry point can be confirmed. According the measured data to puncture during operation, unilateral puncture can reach the distribution effect of the bilateral puncture in the treatment of thoracolumbar compression fractures.
