Objective To investigate the roles of myeloid differentiation factor 88 (MyD88) and TIR domain-containing adaptor inducing interferon-β (TRIF) in sepsis-induced myocardial dysfunction, and to analyze whether strain rate (SR) can be early sensitive evaluation for septic heart failure.Methods Sixty-four healthy male C57BL/6 mice were divided into four groups by random number table (n = 16 in each group): sham group, cecum ligation and puncture (CLP)-induced sepsis model group, anti-MyD88 group and anti-TRIF group. The anti-MyD88 group and anti-TRIF group were injected with 5μL/g of anti-MyD88 antibody or anti-TRIF antibody through the tail veins 2 hours before CLP. Eight animals in each group were used to observe the survival of 24 hours, and the other 8 myocardial tissues were harvested for examination. The cardiac function was evaluated by echocardiography before and 6 hours and 12 hours after operation. The mRNA expressions of MyD88, TRIF and inflammatory factors in myocardium were measured by polymerase chain reaction (PCR) at 24 hours after operation, and the degree of neutrophils infiltration was detected by myeloperoxidase (MPO) activity.Results The number of 24-hour survive in anti-MyD88 group and anti-TRIF group were higher than that in CLP group (number: 4, 3 vs. 2,P = 0.044,P = 0.047). Compared with sham group, the cardiac function was significantly decreased, the mRNA expressions of myocardial tissues MyD88, TRIF, interleukin (IL-1, IL-6) and tumor necrosis factor-α (TNF-α) were significantly increased, and the infiltration of neutrophils were obvious in CLP group. Compared with CLP group, the left ventricular short axis fractional shortening rate (FS) and SR were significantly increased after 12 hours in anti-MyD88 group and anti-TRIF group [FS: (49.52±1.78)%, (49.89±1.49)%vs. (41.11±1.63)%, SR (s-1): 17.63±2.16, 17.85±1.64 vs. 12.55±1.84]; the mRNA expressions of MyD88, TRIF and inflammatory factors were significantly decreased [MyD88 mRNA (A value): 0.463±0.046, 0.505±0.048 vs. 0.638±0.102, TRIF mRNA (A value): 0.413±0.031, 0.410±0.021 vs. 0.625±0.057, IL-1 mRNA (A value):0.569±0.101, 0.570±0.091 vs. 0.946±0.171, IL-6 mRNA (A value): 0.551±0.143, 0.431±0.157 vs. 0.850±0.194, TNF-α mRNA (A value): 0.471±0.082, 0.444±0.093 vs. 0.707±0.094]; and the infiltration of neutrophils were significantly decreased [MPO (U/L): 62.34±2.60, 60.87±2.40 vs. 73.83±4.90], with statistically significant differences (allP < 0.05). There was no statistical difference in above parameters between the anti-MyD88 group and anti-TRIF group (allP > 0.05).Conclusions Blocking MyD88 and TRIF expression play significant and similar roles in protecting cardiac deterioration from sepsis by attenuating cytokine release, reducing neutrophil infiltration. SR can sensitively assess septic cardiac dysfunction.

BACKGROUND:There are stil some controversies about lateral compression rotational y unstable pelvic ring injuries and fixed mode. OBJECTIVE:To evaluate the pelvic stability of locking plate fixation pelvic reconstruction repairing lateral compression rotational y unstable pelvic ring injuries. METHODS:We retrospectively analyzed 15 patients with unstable lateral compression rotational y unstable pelvic ring injuries treated with reconstruction locking plates fixation at Suzhou Xiangcheng People’s Hospital between November 2011 and November 2014. The Matta standard was used to evaluate the quality of fracture reduction. Clinical efficacy was evaluated by Majeed score. RESULTS AND CONCLUSION:Fifteen patients were fol owed up for 12-44 months (mean 24 months). According to the standard of Matta, 11 cases were excel ent, 2 cases were good, 2 cases were average, 0 case poor, and the excel ent and good rate was 87%. According to Majeed functional assessment, clinical function outcomes were graded as 9 cases excel ent, 3 cases good, 1 case average, 1 case poor;excel ent and good rate was 80%. There were no patient loss of reduction and internal fixation failure among these 15 patients in the final fol ow-up. No iatrogenic neurovascular injury occurred. Incision superficial infection was detected in 2 patients with a Morel-Laval ee lesion after subjecting to double-tube continuous negative pressure drainage, and healed after wound management. A large area of infection and skin necrosis did not occur. These results confirm that pelvic universal reconstruction locking plates in repair of lateral compression rotational y unstable pelvic ring injuries can maintain a strong and effective fixation. We should pay much attention to the cases of pelvic fractures combined with soft tissue injury around the pelvis.
