ABSTRACT
【Objective】 To evaluate the safety and efficacy of balloon-expandable vertebral body stenting （VBS） in treating elderly patients with osteoporotic vertebral compression fractures. 【Methods】 Thirty-eight elderly patients with osteoporotic vertebral compression fractures were randomly divided into two groups according to the parity of their hospital admission numbers to receive VBS and traditional percutaneous kyphoplasty （PKP）， respectively. The two groups were compared regarding changes in the intensity of pain， functional score， imaging parameters related to vertebral compression， and sagittal Cobb angle as well as the incidence of bone cement leakage after treatment， to evaluate the safety and efficacy of VBS. 【Results】 All the patients underwent the operations smoothly， which were performed with the bilateral percutaneous puncture technique under local anesthesia by the same surgeon， and were followed up for more than half a year. Both VBS group and PKP group showed significant improvement in the visual analogue scale score， the Oswestry disability index， the height of the fractured vertebral body， and the Cobb angle at 3 days， 1 month， 3 months and 6 months after treatment （all P<0.05）. There were significant differences in those indicators between the two groups （all P<0.05）. 【Conclusion】 VBS is an effective treatment approach for elderly patients with osteoporotic vertebral compression fractures. It can effectively recover fractured vertebral body height， relieve patients’ pain， and have fewer complications such as bone cement leakage.
ABSTRACT
Objective To assess the clinical utility of measurement of plasma heparin-binding protein (HBP) in diagnosis and prognosis of sepsis.Methods This is a retrospective study on the performance of plasma heparin-binding protein, procalcitonin and C-reaction protein in the early diagnosis of sepsis. Thirty-one patients with sepsis, 16 patients with severe sepsis, 12 patients with septic shock and 37 control patients without confirmed sepsis, all admitted to the Intensive Care Units (ICU) of the Third Hospital Affiliated to Wenzhou Medical University and Wenzhou Central Hospital from August 2014 to November 2016, were enrolled in the study. The plasma level of HBP, procalcitonin (PCT) and C-reactive protein (CRP) were measured, and the detailed clinical data were retrieved from the patient chart records for all patients described above. Comparison of each laboratory and clinical parameters between groups was carried out by Non-parameter Test. The efficiency of each parameter was calculated by receiver operating characteristics curves (ROC) analysis. The correlation between HBP, PCT or CRP and clinical or other laboratory parameters was explored using Spearman correlation analysis.Results HBP was significantly elevated in patients with severe sepsis[(100.65±58.82)ng/ml and(31.86±36.87)ng/ml,Z=-3.856,P<0.05;(100.65±58.82)ng/ml and(24.96±17.49)ng/ml,Z=-3.556,P<0.05]and in patients with septic shock[(148.28±99.73)ng/ml and(31.86±36.87)ng/ml,Z=-4.432,P<0.05;(148.28±99.73)ng/ml and(24.96±17.49)ng/ml,Z=-4.157,P<0.05], respectively, while CRP[(154.64±62.90)mg/L and(92.56±67.49)mg/L,Z=-2.749,P<0.05;(154.64±62.90)mg/L and (79.21±51.80)mg/L,Z=-3.218,P<0.05]and PCT[(32.86±39.93)ng/ml and(2.70±6.24)ng/ml,Z=-3.395,P<0.05;(32.86±39.93)ng/ml and(4.21±14.94)ng/ml,Z=-4.092,P<0.05]were increased only in patients with septic shock (P<0.05).For HBP, the area of under the ROC curves (AUC) was the biggest (AUC=0.687), indicating the clinical significance(P<0.05) with excellent sensitivity(0.729) at the optimal cut-off value(18.58 ng/ml). In addition, HBP(APTT: r=0.244, P=0.016;PT: r=0.351, P<0.001;INR: r=0.314, P=0.002;D-Dimer: r=0.334, P=0.001;lactic acid: r=0.394, P<0.001), CRP(APTT: r=0.271, P=0.008;PT: r=0.348, P=0.001;INR: r=0.264, P=0.009;D-Dimer: r=0.257, P=0.012;lactic acid: r=0.329, P=0.001) and PCT(APTT: r=0.375, P<0.001;PT: r=0.523, P<0.001;INR: r=0.535, P<0.001;D-Dimer: r=0.254, P=0.013;lactic acid: r=0.422, P<0.001)were positively correlated to coagulation function and to lactate.Conclusion HBP could probably be acted as an important biomarker for diagnosis and prognosis for patients with sepsis, esp., for patients with severe sepsis and septic shock.
ABSTRACT
Abstact:Objective To explore the effect of different arrangement of hollow screws in treatment of femoral neck fracture.Methods The clinical data of 160 cases with femoral neck fracture from March 2010 to May 2014 in our hospital were collected.They were randomly di-vided into triangle group and inverted triangle group according to arrangement of hollow screws.The operation time,intraoperative blood loss, fluoroscopy frequency in operation,length of stay,time of fracture healing,postoperative complications,Harris score and functional recovery of two groups were recorded and compared.Results The operation time and intraoperative blood loss in inverted triangle group were lower than those in triangle group,the difference was significant(P 0.05).Conclusion Inverted tri-angle hollow screws treating femoral neck fracture makes surgery operation easier,operative time shorter and blood loss smaller.
