Objective To investigate the relationship between brain natriuretic peptide (BNP)and heart function in elderly patients with acute myocardial infarction.Methods All data were taken from the hospitalized cases with acute myocardial infarction from December 2008 to August 2010.100 patients aged from 60 to 97 were enrolled.The data were divided into 4 groups (group 1,24 cases; group 2,32 cases,group 3,23 cases; group 4,21 cases) respectively according to Killip's classification.Left ventricular function was measured by echocardiography.Plasma BNP was determined with enzyme immunoassay.Results Compared with non heart failure group and normal group,heart failure group had much higher plasma BNP concentrations.The plasma BNP level had positive correlation with left ventricular end diastolic diameter (r =0.27,P < 0.01) and left ventricular end-diastolic dimension (r=0.37,P<0.01),while,had a negative correlation with left ventricular ejection fraction (r =-0.38,P < 0.01).Conclusions Plasma BNP level was significantly elevated which could evaluate the heart function in elderly patients with acute myocardial infarction.

Objective To access the effectiveness of modified early warning score (MEWS) and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) in predicting the degree of injury and outcome for emergently admitted polytrauma patients.Methods In this single-center prospective study,266 polytrauma patients hospitalized from June 2012 to January 2013 were enrolled.MEWS and APACHE Ⅱ score were collected and compared for the rate of ICU admission,high dependency unit admission,outpatient therapy,death,and discharge within 30 days.Diagnostic and predictive performance of MEWS and APACHE Ⅱ were assessed by the receiver operating characteristic curve (ROC).Results A higher values in MEWS and APACHE Ⅱ were linked to much severe injury,increased likelihood of admission to the ICU or high dependency unit and high mortality.Patients with MEWS value ≥5 had increased risk of death as compared with those with MEWS value < 5 (x2 =90.749,P <0.01).MEWS =5,for injury severity evaluation,showed a sensitivity of 85.7% and specificity of 84.8%.MEWS value≥5 predicted ICU admission with a sensitivity of 80.0% and specificity of 91.1% and high dependency unit admission with a sensitivity of 67.9% and specificity of 79.9%.APACHE Ⅱ score ≥ 21 was associated with increased rate of death,with significant difference from that among patients with APACHE Ⅱ score < 21 (x2 =73.518,P < 0.01).APACHE Ⅱ score =21,for injury severity evaluation,showed a sensitivity of 90.5% and specificity of 79.5%.APACHE Ⅱ score ≥ 21 predicted ICU admission with a sensitivity of 95.0% and specificity of 73.6% and high dependency unit admission with a sensitivity of 88.2% and specificity of 72.8%.In prediction of prognosis,ICU admission and high dependency unit admission,area under the ROC curve with 95% CI for NEWS was 0.889 (0.830-0.948),0.937 (0.900-0.975) and 0.946 (0.916-0.977) respectively and for APACHE Ⅱ was 0.939 (0.898-0.979),0.761 (0.677-0.845) and 0.832 (0.782-0.883) respectively.MEWS and APACHE Ⅱ score in death group were (6.4 ± 2.7) points and (29.9 ± 6.4) points,but lowered to (3.0 ± 1.5) points and (16.8 ± 5.7) points respectively in survival group (P < 0.01).Conclusions Both APACHE Ⅱ and MEWS have the ability to discriminate the severity of polytrauma patients and identify the potential of seriously ill patients.MEWS is more suitable for early identification of critically ill trauma patient due to its easy and quick operation as well as low cost,while APACHE Ⅱ is more suitable for evaluation of emergency observing patients and ICU patients.

BACKGROUND:Studies have exhibited that symmetrical distribution and effective dose of bone cement can reduce postoperative vertebral refractures and help improve outcomes,but obtaining better distribution and dose of bone cement during percutaneous vertebroplasty remains an issue for surgeons. OBJECTIVE:To investigate the risk factors of percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fracture,and to analyze the correlation between these factors and recurrent fractures of the operative vertebral body and adjacent vertebral bodies after percutaneous vertebroplasty. METHODS:111 patients who underwent unilateral approach percutaneous vertebroplasty in Sixth Affiliated Hospital of Xinjiang Medical University from January 2018 to December 2021 were screened and divided into fracture group(n=17)and non-fracture group(n=94)according to whether refracture was observed during follow-up.The following variables were reviewed in both groups:Gender,age,body mass index,operation time,menopause age,bone cement distribution index,bone density T value,bone cement dose,location of bone cement distribution,percutaneous vertebroplasty stage,past history,adverse reactions and disc cement leakage of patients.These variables were analyzed by univariate analysis.The statistically significant factors were replaced by a binary Logistic regression model to analyze the correlation with vertebral refracture after percutaneous vertebroplasty. RESULTS AND CONCLUSION:(1)Univariate analysis demonstrated that after percutaneous vertebroplasty,vertebral refracture was associated with disc cement leakage(P=0.000),cement dose(P=0.049),and cement distribution location(P=0.017).(2)Binary Logistic regression revealed that bone cement leakage(P=0.000),cement dose(P=0.031),and location of cement distribution(P=0.015)were risk factors for recurrent fracture of the operative vertebral body and adjacent vertebral body after percutaneous vertebroplasty.Compared with cement distribution types I,II,and III,the risk of recurrent fracture in the operative and adjacent vertebrae was higher in cement distribution types IV and V(OR=36.340,P=0.016;OR=27.755,P=0.017).(3)It is concluded that recurrent fractures of the surgically operated vertebral body and adjacent vertebral bodies are caused by the interaction of multiple risk factors.Bone cement distribution and bone cement leakage were independent risk factors.Recurrent fractures of the operative vertebra and adjacent vertebrae are more likely when the cement is distributed in type IV and type V.Surgeons should fully assess these risk factors before surgery and develop targeted prevention and treatment strategies to help reduce the risk of future refractures.

OBJECTIVE:To compare the efficacy and safety of terlipatide and bisphosphate in the treatment of postmenopausal osteoporosis fractures through a Meta-analysis. METHODS:By searching PubMed,Cochrane Library,EMbase,CNKI,WanFang and VIP databases,18 randomized controlled studies on terlipatide and bisphosphate in the treatment of postmenopausal osteoporosis fractures were included according to inclusion and exclusion criteria.Endnote X9 software was used to manage the literature and Revman 5.3 software was used to perform a Meta-analysis on the extracted data.The incidences of vertebral fracture,non-vertebral fracture and adverse reaction in postmenopausal osteoporosis patients treated with terlipatide and bisphosphate were analyzed. RESULTS:A total of 18 randomized controlled studies were included,of which 10 were of medium and high quality and 8 were of low quality.Meta-analysis results showed that the fracture incidence in the teriparatide group[risk ratio(RR)=0.56,95%confidence interval(CI):0.48-0.66,P<0.000 01]was lower than that in the bisphosphonate group,and teriparatide was superior to alendronate in preventing fractures in postmenopausal women with osteoporosis(RR=0.50,95%CI:0.35-0.69,P<0.000 1)and other bisphosphonates(RR=0.58,95%CI:0.49-0.70,P<0.000 01).During the follow-up over 18 months,teriparatide was superior to bisphosphonates in preventing fractures in postmenopausal women with osteoporosis(RR=0.56,95%CI:0.48-0.69,P<0.000 01).In addition,we found that teriparatide was superior to bisphosphonates in preventing vertebral fractures(RR=0.48,95%CI:0.37-0.62,P<0.000 01)and non-vertebral fractures(RR=0.63,95%CI:0.51-0.78,P<0.000 1)in postmenopausal women with osteoporosis.Teriparatide was superior to bisphosphonates in increasing lumbar bone density[odds ratio=4.16,95%CI:2.96-5.36,P<0.000 1)and femoral neck bone density(odds ratio=1.02,95%CI:0.04-2.01,P=0.04).There was no significant difference in adverse reactions between teriparatide and bisphosphonates(RR=0.95,95%CI:0.85,1.06,P=0.37). CONCLUSION:Teriparatide is superior to bisphosphonates in preventing vertebral and non-vertebral fractures in postmenopausal women with osteoporosis,but the safety and adverse drug reactions of teriparatide and bisphosphonates are basically similar.Teriparatide is superior to bisphosphonate in preventing fracture and improving lumbar and femoral neck bone density regardless of short-term(<18 months)or long-term(≥18 months)use.
