High-resolution magnetic resonance imaging (HRMRI) is a safe, non-invasive, inexpensive, accurate and reproducible clini-cal imaging modality, and the results can acutely reflect the extent of atherosclerotic disease and have high predictive values for future clini-cal events. It uses black blood imaging techniques and can obtain sufficient sensitivity for submillimetre imaging. HRMRI has been used widely to visualize the vessel wall and differentiate the components of atherosclerotic plaques. It is of important clinical meaning to evaluate plaque vulnerability with HRMRI, which is related to the remodeling pattern, plaque burden, intraplaque hemorrhage and contrast enhance-ment, and plaque distribution, etc.

BACKGROUND:Tissue-engineered bone in the treatment of large bone defects has obvious advantages especial y when the autologous ilium transplantation is limited, which can effectively fil bone defects.
OBJECTIVE:To investigate the rationality of intramedul ary nailing support and tissue-engineered bone fil ing in the treatment of fibrous dysplasia of the proximal femur and the biocompatibility of the tissue-engineered bone.
METHODS:Seven patients with fibrous dysplasia of the proximal femur were subjected to intramedul ary nailing support and tissue-engineered bone fil ing.
RESULTS AND CONCLUSION:Al of the seven patients underwent more than 8 months of fol ow-up, no rejection reaction and other complications occurred. After 4-6 weeks of fixation, al the seven patients removed hip spica braces, with a good hip mobility. After 10-12 weeks, X-ray review showed no pathological fracture, internal fixation loosening and narrow neck stem angle. Using the Harris hip score evaluation of the hip function, the affected side of the seven patients was optimized. After 16-18 weeks, X-ray films reviewed good creeping substitution in the affected area treated with the intramedul ary nailing support and bone graft. After 24-26 weeks, new bone appeared within the scope of lesions. After 1.0-1.5 years, bone creeping substitution was basical y completed in the intertrochanteric region, and original lesions were invisible on X-ray films. These findings confirmed that intramedul ary nailing support and tissue-engineered bone fil ing for treating fibrous dysplasia of the proximal femur has good effectiveness, exhibiting stable internal fixation and avoiding resection of autogenous iliac bone. Tissue-engineered bone has a good biocompatibility in the medium-term fol ow-up, with good hip function activities.

Objective To investigate the correlation between red cell distribution width RDW) and prognosis in patients with severe traumatic brain injury.Methods A total of 264 consecutive patients with severe traumatic brain injury admitted from May 2012 to November 2014 were enrolled.The patients were divided into low-RDW group (RDW ＜ 15％,n =198) and high-RDW group (RDW ≥ 15％,n =66) based on their RDW levels.Between-group differences were evaluated on general conditions,acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ),inflammatory markers [high sensitivity C-reactive proteins(hs-CRP) and arterial lactate],liver/renal dysfunction,and 28-day mortality.Spearman correlation analysis of RDW with mortality was conducted.Independent factors of 28-day mortality were identified using multivariate Logistic regression.Kaplan-Meier 28-day survival curve was analyzed and survival probability of the two groups was compared using Log-Rank test.Results The 28-day mortality was significantly enhanced in high-RDW group compared to that in lowRDW group (43.9％ vs 26.8％,P ＜ 0.01).RDW ≥ 15％ related positively to APACHE Ⅱ and mortality(r =0.172 and 0.253 respectively,P ＜ 0.01),but negatively to Glagow coma score (GCS) (r =-0.169,P ＜0.01).RDW≥ 15％ was the independent risk factor for predicting the 28-day mortality (OR =2.144,95％ CI 1.202-3.826,P ＜0.01).After adjusted gender,age,and other relative factors,RDW≥15％ was still strongly correlated with the 28-day mortality(OR =2.244,95％ CI 1.076-4.678,P ＜ 0.05).Significantly lower 28-day survival rate was found in high-RDW group than in low-RDW group (P ＜ 0.01).Conclusions RDW level rises beyond the normal range on admission in patients with severe traumatic brain injury,which is closely correlated with the 28-day poor outcome.RDW≥ 15％ has significant predictive value in the prognosis.

Objective To understand the clinical features of candidemia.Methods A retrospective analysis was performed based on the data of 88 candidemia cases treated in Huashan Hospital during the period from 2007 to 2012.The clinical data were re-viewed in terms of species distribution,underlying diseases,clinical manifestations,treatment and outcomes.The prognostic factors were analyzed by chi-square test or Fisher exact probability test.Multivariate analysis was conducted by multiple Logis-tic regression.Results Candida albicans (40/88,45.5%)was the most common pathogen isolated from these candidemia ca-ses,followed by Candida tropicalis (20/88,22.7%),Candida parapsilosis (17/88,19.3%),Candida glabrata (10/88, 11 .4%),and Candida krusei (1/88,1 .1 %).Solid malignancy,diabetes,and surgical procedure were the most frequently identified underlying diseases.Fatal or deteriorative outcome was reported in 28 cases.The attributable mortality was 18.2%. Multivariate prognostic analysis indicated that presence of central venous catheter (OR:6.322,95% CI :1 .055-37.891 ,P =0.044)was independently correlated to increased mortality.Appropriate antifungal therapy was an independent predictor of de-creased overall mortality (OR:0.137,95% CI :0.039-0.480,P =0.002).Conclusions The pathogen distribution of candi-demia has changed slightly.Appropriate antifungal therapy plays a key role in the treatment of candidemia.

Objective To explore the impact of preoperative neoadjuvant chemotherapy on the expressions of multi-drug resistance genes in patients with cervical cancer and its relationship with the effect of chemotherapy. Methods Ninety-eight cervical cancer patients with TP regimen selected to perform preoperative chemotherapy were enrolled in the Affiliated Hospital of Guiyang Medical College between January 2010 and June 2014. Immunohistochemisty (En vision method) was used to determine the expressions of P-gP, GST-π and TopoII of the same patients before and after neoadjuvant chemotherapy and explore the relationship with the effect of chemotherapy. Results The positive expression rates of P-gp and GST-π were 71.43% and 64.29% before chemotherapy and 80.61%and 74.49%after chemotherapy, respectively. The former two had significant differences (P<0.01). The positive expression rates of TopoII was 48.98%before chemotherapy and 28.57%after chemotherapy , respectively, showing significant differences (P < 0.01). The expressions of P-gp, GST-π and TopoⅡ gene were not affected by the clinical and pathological features of cervical cancer (P > 0.05). Before neoadjuvant chemotherapy, the positive expression of GST-π in the ineffective group was statistically higher than that in the effective group (P<0.05). The positive expressions of P-gp and Topo II showed no statistical significance between the effective group and the ineffective group (P > 0.05). There was significant correlation in the expressions of P-gp, GST-π and TopoⅡ(P < 0.05) before and after neoadjuvant chemotherapy. Conclusions The expression of P-gp, GST-πand TopoⅡgene may not be affected by the clinical and pathological features of cervical cancer, but may change expressions of multi-drug resistance genes in cervical cancer by neoadjuvant chemotherapy. Monitoring their expression has a guiding significance for drug selection, prognostic judgment, and the following treatment regimen decision. The GST-π, expression level can be used as a biological parameter to predict the effect of TP regimen neoadjuvant chemotherapy.

OBJECTIVE:To investigate clinical efficacy and safety of recombinant human tissue type plasminogen activator (rt-PA) intravenous thrombolytic in the treatment of elderly patients (over 75 years old) with acute cerebral infarction (ACI). METHODS:78 elderly ACI patients,on the basis of routine treatment,were divided into thrombolysis group (40 cases) and non-thrombolysis group (38 cases) according to the will of patients or family members. Non-thrombolysis group received aspirin 200 mg,qd;thrombolysis group was given rt-PA 0.9 mg/kg(maximum dose of 90 mg)by intravenous push of 10% dose within 1 min,and intravenous dripping of residue dose within 60 min;receiving aspirin 200 mg,qd,24 h after thrombolytic therapy with-out contraindications. Both groups were treated for 14 days. The effective rate,NIHSS score before treatment and 24 h,7 d and 14 d after treatment,prognosis after 90 d were compared between 2 groups,and the occurrence of ADR was observed in 2 groups. RE-SULTS:The total effective rate was 67.50% in thrombolysis group and 52.63% in non-thrombolysis group,with statistical signifi-cance(P<0.05);there was significant difference in NIHSS score between 2 groups 24 h,7 d,14 d after treatment(P<0.05);90 d prognosis of thrombolysis group was superior to that of non-thrombolysis group,there was statistically significance (P<0.05);there was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:4.5 h time window rt-PA intravenous thrombolytic therapy is safe and effective for elderly patients with ACI,and can reduce disability and fatality,im-prove prognosis.
