Objective To assess myocardial ischemia in metabolic syndrome (MS), and risk factors of coronary heart disease (CHD) in MS, and to evaluate myocardial nuclein perfusion imaging (MPI). Methods 140 in-patients were divided into three groups according to the diseases they suffered from: metabolic syndrome (MS): 82 cases (m/f=54/28), essential hypertension (EH): 38 cases (m/f=15/23), and diabetes mellitus (DM): 20 cases (m/f=10/10). The degree of myocardial ischemia was detected by myocardial perfusion single-photon emission computed tomography (SPECT MPI). Results (1) The percentage of myocardial ischemia in MS group was 81.7%, and 56.8% of the patients in this group suffered from severe ischemia. Both percentages were higher than that in the other two groups (P

Objectives To investigate the r el ationship between pancreatic ischemia and cytokines released in rats with acute pancreatitis(AP). Methods 20 acute edematous pancreatitis(AEP) and 20 acute necrotizing pancreatits(ANP) rat models wer e induced by injection of sodium taurocholate into the pancreatic duct, another 10 normal rats were used as control. At 12 hours after the induction of AP, 10 r ats in each group were sacrificed, blood and pacreatic tissue samples were taken for measurement of TNF-? and IL-10 levels. The pathological study of pancre as was performed, and pancreatic blood flow(PBF) was measured by Doppler ultraso und instrument.Results The TNF -? and IL-10 levels in serum and pancreatic tissue increased after the induction of AP, IL-10 levels elevated more significantly in AEP rats, TNF-? levels e levated more significantly in ANP rats. PBF reduced in AP rats, and the amplitud e of PBF measured by Doppler ultrasound was closely correlated with serum and ti ssue TNF-?, IL-10 levels, inflammation, hemorrhage and necrosis scores.Conclusion The reduction of PBF and the i ncreasement of cytokines developed simultaneously in rats with AP, hence both of them are important pathogenic factors of AP.

ObjectiveTo investigate and compare the efficacy, safety, and cost effectiveness in the treatment of painful osteoporotic vertebral compression fractures ( OVCFs ) with percutaneous vertebroplasty (PVP) and kyphoplasty(PKP). MethodsSeventy-two patients (96 vertebrae) with painful OVCFs were treated by PVP (n ＝34) or PKP (n ＝38) under radiological monitoring. After bone biopsy needle into the compressed vertebra, bone cement (polymethylmethacrylate) was injected in PVP group, and that was inserted followed by the inflation of vertebra to create cavities in PKP group. The fluoroscopy time, total amount of bone cement injected, and cost were recollected respectively. The score of visual analogue scale point( VAS, 10-point scale)was determined at before the procedures, and 24 hours, one week, and one month after the procedures.Pain relief and complications were observed.The Cobb angle and vertebral heights of the anterior, middle, and posterior border were measured pre-and post-operative. ResultsThe two procedures were technically successful in all patients. The follow-up ranged from 1. 0 to 34. 0 months [mean time, (8. 9 ±3.2) months]. The Mean fluoroscopy time of treating per vertebra in PVP group was ( 11. 1 ± 10. 6 ) min, which was significant shorter than that ( 23.5 ± 13. 0) min in PKP group( P ＜0. 05 ).The mean total cost per patient was (5127. 2 ± 502.3 ) yuan in PVP group, which were strikingly lower than that(32 301.4 ±3204. 6) yuan in PKP group (P ＜0. 05).(3)There was no significant difference( P ＞0. 05 ) in average cement volumes in PVP group [ (4. 9 ± 1.1 ) ml]and PKP group [ (5.4 ± 1.7 ) ml]. Pain relief of was observed in 94. 1％ (32/34) of PVP group and in 92. 1％ (35/38) of PKP group. The score of VAS at pre-operation was (8. 3 ±0. 4 vs 7.9 ±0. 8) ,and at post-operative 24 h (2. 9 ±0. 9 vs 2. 8 ± 1. 2),1 week (2.6 ± 0. 9 vs 2.6 ± 1. 1 ), and 1 month (2.6 ± 0. 9 vs 2. 5 ± 1.3 ) were no difference at PKP and PVP group(P ＜0.05). There was significant difference between pre- and post-operative time point in each group. The Cobb angle, anterior and middle height of vertebra was corrected in both PVP and PKP group. In PVP group, the preoperative Cobb angle, anterior and middle height of vertebra was (24. 2 ± 3.8 )°,( 19. 1 ± 1.4) mm, (25. 2 ± 1.0) mm, which was significant different ( P ＜ 0. 05 ) from that of ( 19.4 ±3.9)°, (21.0 ± 1.5) mm, (27.0 ± 1.2) mm at pre-operation.In PKP group,there was significant difference (P ＜ 0. 05 ) in the preoperative Cobb angle, anterior and middle height of vertebra [(25. 1 ±5.0)°vs(10.7 ±2.8)°, (19.5 ± 1.5) mm vs (24.3 ± 1.9) mm, (25.4 ± 1.1) mm vs (29.7 ±1.3) mm, respectively]. As to the above index, the overall correcting effect in PKP was much better than that in PVP( P ＜0. 05 ). Cement leakage occurred in 9 cases in PVP group and 3 cases in PKP group ( P ＜0. 05 ) but no symptoms. There were no major complications during operation in the two groups. Conclusion PVP and PKP are effective and safe in the treatment of painful OVCFs but PVP is more cost effective than PKP.
