Objective To assess the impact of tranexamic acid on visible and hidden blood loss after the preliminary unilateral total hip arthtoplasty (THA).Methods The study involved 60 patients who received primary unilateral THA due to femoral neck fracture from March 2010 to September 2011.They were 18 males and 42 females,at 58 to 86 years of age (average 74.5 years).They were divided into Group A (n =20),not given tranexamic acid,Group B (n =20),given tranexamic acid in operation,Group C (n =20),given tranexamic acid at preoperative one hour according to stratified random method.Total red blood cell loss,visible red blood cell loss,and hidden red blood cell loss in each group were calculated.Results Visible red blood cell loss in Groups A,B,and C was (95.4 ± 17.7) ml,(45.5 ± 11.5) rnl,and (45.3 ± 8.4) ml respectively.Moreover,difference of visible red blood cell loss was significant between Groups A and B (P ＜ 0.05),but insignificant between Groups B and C (P ＞ 0.05).Hidden red blood cell loss in Groups A,B,and C was (322.4 ± 57.7) ml,(203.8 ±46.6) ml,and (137.6 ± 34.7) ml respectively,with significant difference between Groups A and B (P＜0.05) and between Groups B and C (P＜0.05).Conclusions Tranexamic acid reduces the visible and hidden blood loss in primary unilateral THA significantly.While tranexamic acid administered at preoperative one hour gains advantage of less hidden blood loss over the intraoperative administration.

Objective To compare the clinical outcomes and safety of synchronous vs staged bilateral total hip arthroplasty (THA).Methods Fifty-eight cases (116 hip joints) undergone bilateral THA from January 2008 to January 2010 were reviewed retrospectively.Follow-up period was postoperative 2 years,including synchronous bilateral THA in 29 cases (synchronous group) and staged bilateral THA in 29 cases (staged group).The two patient groups were compared in aspects of total operation time,total amount of blood loss,total amount of blood transfusion,duration and cost of hospitalization,postoperative discrepancy in bilateral leg length,preoperative and postoperative function score and perioperative complications.Results During the follow-up,no complications of incision infection,deep vein thrombosis and prothesis dislocation or loosening were noted.And postoperative delirium symptoms occurred only in four cases (three in synchronous group and one in staged group).There were no statistical differences between synchronous group and staged group in aspects of total operating time [(117.9 ± 23.8) minutes vs (124.1 ± 18.8) minutes],total amount of blood loss [338.1 ml (180-720 ml) vs 303.9 ml (200-600 rnl)],total amount of blood transfusion [227.6 ml (0-800 ml) vs 189.7 ml (0-400 ml)],postoperative function score.However,differences of the following data were considered statistical significance between synchronous group and staged group:expense of hospitalization [9.5 ten thousand yuan (7.0-11.3 ten thousand yuan) vs 10.5 ten thousand yuan (8.8-11.0 ten thousand yuan)],length of hospitalization [(12.1 ±3.2) days vs (20.1 ±3.5) days],postoperative discrepancy in bilateral leg length [(0.11 ± 0.22) cm vs (0.42 ± 0.44) cm].Conclusions Synchronous bilateral THA is safe and feasible as far as the patients' physical condition is allowed,perioperative management is rational and physicians have mature surgical techniques.Moreover,it gains advantage over staged bilateral THA considering cost of hospitalization,length of hospitalization and postoperative discrepancy in bilateral leg.

OBJECTIVETo investigate the effect of Antrodia cinnamomea on gene expression related to aortal endothelial injury of rats with hyperlipidemia.

METHODFifty SD rats were randomly divided into five groups: the normal control group (NG), the model group (MG), the antrodia cinnamomea groups of low, middle and high doses (AC-LG, AC-MG, AC-HG, 250, 500, 1 000 mg x kg(-1)). The rats were fed with high-fat diets to establish the hyperlipidemia model. After the drug administration for 10 weeks, their serum lipid, SOD, MDA and ox-LDL, LOX-1, P38 MAPK and NF-kappaB mRNA and protein expression were respectively determined, and the aortal endothelial injury was observed under electron microscope.

RESULTIn the model group, the contents of TC, TG and LDL-C significant increased (P < 0.01), whereas the content of HDL-C significant decreased (P < 0.01). Compared with the model group, both the AC-M group and the AC-H group showed reduction in endothelial injury and significant decrease in the content of TC, TG and LDL-C (P < 0.05 or P < 0.01). The content of HDL-C increased, but with no significant difference. SOD activity in serum remarkably increased (P < 0.05 or P < 0.01), MDA and ox-LDL levels dramatically decreased (P < 0.05 or P < 0.01).

CONCLUSIONA. cinnamomea can alleviate endothelial lipid injury by inhibiting the expressions of LOX-1, P38MAPK and NF-kappaB in aorta and better protect aortal endothelial cells from oxidative lipid injury.

OBJECTIVE To analyze the major reasons of wound infection after external fixator application and then introduce management measures to prevent following wound infections. METHODS Totally 542 patients adopting external fixators between May 2005 and May 2007 were retrospectively reviewed. All the external fixator-related infections were inspected and the excretions from these infected wounds were collected to perform bacterial culturing. RESULTS The total infection rate of these 542 patients after external fixator application was 2.77%. Among them, six were infected with the bacteria in distraction osteogenesis group and the infection rate was 8.82%; three were infected in bone un-union and bone defect group and the infection rate was 5.36%; whilest the common fracture-fixing group got the lowest infection rate of 0.39%. CONCLUSIONS Wire-crossing positions are the most frequently infected sites after external fixation and the drug-resisted bacteria are the most commonly detected pathogens. Thus, increasing the stability of fixators, enhancing the infection supervision of operation environment, draining the wound thoroughly and using antibiotics rationally are the most effective managing measures to prevent external fixator-related infections in orthopedics.
