To observe the preventive effect of polydatin on diabetic myocardial hypertrophy in mice and discuss its and mechanism. The diabetic model was induced with low dose STZ (40 mg x kg(-1) x d(-1) x 5 d, ip) for five days in mice. The myocardial hypertrophy was determined by hypertrophy indexes (LVHI, left ventricular/right ventricle and septum), left ventricular/body weight (LV/BW), the histological examination and the mRNA expression of atrial natriuretic factor(ANF). The fast blood glucose(FBG), serum insulin and plasma hemoglobin A1c ( HbA1c) levels were detected, and then HOMA insulin resistance index ( HOMA. IR) was calculated. The mRNA and protein expressions were measured by qRT-PCR and western blotting, respectively. According to the results, the FBG of the model group exceeded 11.1 mmol x L(-1), with notable decrease in BW and significant increase in insulin, HbA1c and HOME. IR, suggesting the successful establishment and stability of the diabetic model. The increases in LVHI, LV/BW, cell surface and ANF mRNA indicated a myocardial hypertrophy in diabetic mice. Meanwhile, the model group showed decrease in mRNA and protein expressions of PPARβ and significant increase in NF-κB p65, COX-2 and iNOS expressions. After the preventation with PD (50, 100 mg x kg(-1) x d(-1)), diabetic mice showed increase in BW, reduction in the levels of FBG, insulin and HbA1 c, relief in insulin resistance and significant recovery in hypertrophy indexes, indicating PD has the protective effect in diabetic myocardial hypertrophy. Meanwhile, PD up-regulated the expression of PPARβ, inhibited the expressions of NF-κB p65, COX-2 and iNOS, demonstrating that PD's protective effect may be related to the activation of PPARβ and the inhibition of NF-κB, COX-2 and iNOS signaling pathways.

BACKGROUNDPulmonary artery sarcoma originating from the pulmonary artery is a rare disease and its prognosis is extremely poor. Most patients are initially thought to have pulmonary embolism.

METHODSFive patients (3 males and 2 females, mean age was (42.0 ± 8.5) years) of primary pulmonary artery sarcomas underwent surgical procedures. Sarcoma resection and right ventricle outflow tract reconstruction were performed.

RESULTSThere was no death 30 days post-operation except one patient. The function of heart was improved to NYHA II.

CONCLUSIONSGiven the significant morbidity and mortality of pulmonary artery sarcomas, an aggressive strategy for resection is indicated. Early diagnosis and complete surgical resection is perhaps the best way to improve patients' survival with pulmonary artery sarcoma.

Objective To evaluate the effect on the reversal of left ventricular aneurysm (LVA) and on heart function of percutaneous coronary intervention (PCI) therapy at different time of acute myocardial infarction (AMI). Methods A total of 326 patients with primary anterior AMI-accompanied LVA diagnosed by left ventriculography (LVG) from January 2001 to July 2004 were enrolled in this study. They were randomized into 4 groups according to the time of accepting PCI:≤3 h group, 4-6 h group, 7-12 h group and one week group. At the baseline and 6 months after AMI, the parameters of left ventricular diastolic volume index (LVEDVI), left ventricular systolic volume index (LVESVI), left ventricular ejection fraction (LVEF), left ventricular wall motion score (LVWMS) and left ventricular end diastolic pressure (LVEDP) were measured by LVG. The paradox volume index (PVI) was measured by equilibrium radionuclide at one week and 6 months after AMI.At 3 year following up to, the major adverse cardiac events (MACE) were recorded. Results At 6 months after PCI, the LVESVI, LVEDVI, WMS and LVEDP were all decreased while LVEF was increased in the four groups as compared with pre-PCl (P<0.05, respectively). Those parameters changed most obviously in ≤3 h group. At the 6th month after PCI, the PVI was lower in ≤3 h group (12.1±2.1)% than in 4-6 h, 7-12 h and one week group [(15.4±2.4)%, (16.5±2.5)% and (20.4±3.7)%, all P<0.05]. Within the 3 years follow-up, the MACE was significantly lower in 3 h, 4-6 h and 7-12 h groups than in one week group, and the mortality was lower too [(2.8%, 3.0% and 3.1% vs. 17.9%, all P<0.05]. Conclusions The early, fully and permanent open of the infraction-related artery can effectively inhibit the left ventricular remodeling process, prevent LVA formation, improve LV function and prognosis.

Objective To investigate the therapeutic effects of Saussurea involucrate injection in severe acute pancreatitis (SAP) in rats.Methods A total of 80 healthy Sprague-Dawley rats were divided into eight groups:SAP group (three hours、48 hours),Saussurea involucrate treated group (three hours、48 hours),ulinastatin control group (three hours、48 hours) and sham operation group (three hours、48 hours),10 rats in each group.After modeling,the rats of SAP group were regularly feeded and the rats of other three group were treated with Saussurea involucrate injection (1.04 mL/kg) intraperitoneal injection,ulinastatin 10 000 U/L tail vein injection,and saline femoral vein injection,respectively and injected every 12 hours.At three hours and 48 hours after treated,blood and pancreatic tissue samples were obtained.The mortality rate,serum amylase level and pathological changes of the pancreas of each group were observed.Serum tumor necrosis factor alpha (TNF-α),interleukin (IL)-6 and IL-10 levels were detected by enzyme linked immunosorbent assay (ELISA).The content of malondialdehyde (MDA) in pancreatic tissues was determined by chemical colorimetry.The level of TNF-α mRNA,IL 6 mRNA and IL-10 mRNA in pancreatic tissues were measured with reverse trascription-polymerase chain reaction (RT-PCR).The activity of nuclear factor kappa B p65 (NF-κB p65) in the pancreatic tissue was tested by immunohistochemistry.Single factor analysis of variance was used to compare multiple groups,and the least significant difference (LSD) method was used in the multiple comparisons between groups.Fisher's exact probability method was performed for rates comparison.Results At 48 hours,there was no statistically significant difference in mortality rate among Saussurea involucrate treated group,SAP group and ulinastatin groups (all P＞0.05).At 48 hours,the histopathology score (8.13 ± 0.64),levels of serum amylase ((2 597.0±214.0) U/L),TNF-α ((254.4±11.6) ng/L),IL-6 ((441.4±14.6) ng/L),levels of pancreatic tissues MDA ((311.0±10.6) mmol/L),TNF-α mRNA(2.04±0.08),IL-6 mRNA (1.77±0.04)and activity of NF-κB p65 ((25.90±2.90)％) of Saussurea involucrate treated group were all lower than those of SAP group (11.40±0.89,(4 780.0±101.0) U/L,(396.0±7.4) ng/L,(664.4± 7.6) ng/L,(418.0± 10.6) mmol/L,2.94±0.03,2.63±0.08 and (51.60±5.27) ％;however level of serum IL-10 ((133.5±6.9) ng/L vs (95.1±5.2) ng/L) and IL-10 mRNA of the pancreatic tissue (1.38±0.06 vs 0.85±0.03) significantly increased (F=253.07、441.63、489.40、2 465.00、196.65、477.89、562.79、131.70、560.18、570.04,all P＜0.01).There was no significant differences in all above parameters between Saussurea involucrate treated group and ulinastatin groups (7.56±0.88,(2 607.0±239.0) U/L,(252.2 ±9.2) ng/L,(443.4±9.6) ng/L,(308.4±9.2) mmol/L,2.10±0.12,1.74±0.04,(26.00±3.67)％,(134.5±7.8) ng/L and 1.42±0.06) at 48 hours (all P＞0.05).Conclusion Saussurea involucrate injection can eliminate oxygen free radicals and prevent to xidation,inhibit NF-κB activation,regulate synthesis and release of cytokines,and alleviate pancreatic injury in SAP rats,but it can not decrease mortality.
