Acute coronary artery syndrome (ACS) was confirmed by coronary arteriography in 398 patients,and 378 healthy persons served as the control group.Serum uric acid in ACS and control group showed normal distribution,and serum uric acid level in ACS group (322?107 )?mol/L was significantly higher than those in control group (302?77)?mol/L (P＜0.01 ).The prevalence of hyperuricemia (HUA) was 27.0% in male patients and 25.2% in female.Systolic blood pressure,diastolic blood pressure,fasting plasma glucose,total cholesterol,triglycerides,creatinine and blood urea nitrogen in ACS group were higher than those in control group (all P＜0.01 ).Muhivariable analyses adjusted for age and sex indicated that raised fasting plasma glucose,total cholesterol,uric acid and mean arterial pressure were risk factors for coronary artery stenosis in ACS,and HUA played a role in the pathogenesis of ACS.

OBJECTIVETo study the protective effects of saponines of stem and leaf of Panax notoginseng (PNSSL) on acute myocardial ischemia in anaesthetic dogs.

METHODThe acute ischemia models were made by ligation of left anterior descending (LAD) artery. The myocardial blood flow (MBF) was determined by ultrasonic doppler. The experiments adopted epicardiogram mapping to measure the scope and degree of myocardial ischemia, quantitative histologic assay (nitroblue tetrazolium, N-BT stain) to determine the size of myocardial infarction. And the endothelin (ET) and thromboxane B2 (TXB2) were measured by radioimmunological assay.

RESULTPNSSL was showed to obviously alleviate the degree of myocardial ischemia (sigma-ST) and narrow the ischemic area indicated by N-BT staining. In addition, PNSSL could increase the MBF of ischemia section. And the treatment could inhibit the ET and TXB2 release induced by ischemia and infarction.

CONCLUSIONPNSSL demonstrated to attenuate the damage subjected to myocardial ischemia and infarction, which may be due to its function of inhibiting the ET and TXA2 release, increasing the MBF, and then improving the damaged cardiac function.

OBJECTIVETo study the changes of partial pressure of oxygen in brain tissue (P(bt)O(2)) and brain temperature (BT) in patient s in acute phase of severe head injury, and to study the effect of mild hypothermia on P(bt)O(2) and BT.

METHODSThe P(bt)O(2) and the BT of 18 patients with severe head injury were monitored, and the patients were treated with mild hypothermia within 20 hours after injury. The rectal temperature (RT) of the patients was kept on 31.5-34.9 degrees C for 1-7 days (57.7 hours+/-28.4 hours averagely), simultaneously, the indexes of P(bt)O(2) and BT were monitored for 1-5 days (with an average of 54.8 hours+/-27.0 hours). According to Glasgow Outcome Scale (GOS), the prognosis of the patients was evaluated at 6 months after injury.

RESULTSWithin 24 hours after severe head injury, the P(bt)O(2) was significantly lower (9.6 mm Hg+/-6.8 mm Hg, 1 mm Hg=0.133 kPa) than the normal value (16-40 mm Hg). After treatment of mild hypothermia, the mean P(bt)O(2) increased to 28.7 mm Hg+/-8.8 mm Hg during the first 24 hours, and the P(bt)O(2) was still maintained within the range of normal value at 3 days after injury. The BT was higher than the RT in the patients in acute phase of severe head injury, and the difference between the BT and the RT significantly increased after treatment of mild hypothermia. Hyperventilation (the partial pressure of carbon dioxide in artery (P(a)CO(2)) approximately 25 mm Hg) decreased the high intracranial pressure (ICP) and significantly decreased the P(bt)O(2).

CONCLUSIONSThis study demonstrates that P(pt)O(2) and BT monitoring is a safe, reliable and sensitive diagnostic method to follow cerebral oxygenation. It might become an important tool in our treatment regime for patients in the acute phase of severe head injury requiring hypothermia and hyperventilation.

OBJECTIVE: To study the morphological characteristics of femurs of adult human and 11 kinds of adult animals from cattle, horses, pigs, goats, sheep, dogs, cats, rabbits, geese, ducks, chickens, and to establish an effective species identification method among various species. METHODS: The 4 cm mid-diaphyseal segment of the femur from adult human (older than 20 years old) at autopsy was obtained. Addi-tionally, the 4 cm ones from 11 kinds of adult animals were obtained. After decalcification, all femurs were made into slices, and then were observed by optical microscope. The 25 indexes were selected and analyzed by step discriminant analysis according to differences between human and mammal, human and poultry, and human and 11 kinds of animals. RESULTS: The histological structure of bone mineral density of middle part of femur had obvious characteristics among the species. And the morphology and number of osteon showed the trend of obvious biological evolution. There were 11 indexes with significant differences between human and 11 kinds of animals to establish some mathematical models to discriminate all species. The correct discrimination rate was 96.3% between human and mammal. The correct discrimination rate was up to 100% between human and poultry, and was 89.4% among human, mammal and poultry. CONCLUSION The mathematical models have good correct discrimination rate among human and the other animals, which could be applied in the practical species identification cases.

OBJECTIVETo investigate the protective effect of grape seed proanthocyanidin (GSP) on spermatogenesis following testicular torsion/detorsion in mice.

METHODSTwenty-four healthy male Kunming mice, aged 8 weeks and weighing 25 - 27 g, were randomly divided into a control, a torsion and a treatment group, each containing 8 animals. The unilateral testicular torsion/detorsion model was established in the treatment and torsion groups. Thirty minutes before detorsion, the animals of the treatment group were injected intraperitoneally with 50 mg/kg GSP, and those of the torsion group with normal saline at the same dose, both for 3 days postoperatively. On the 4th day after surgery, ipsilateral orchiectomy were performed to detect histopathological changes, the levels of superoxide dismutase (SOD) and malondialdehyde (MDA), and the apoptotic index (AI) of germ cells in all the mice.

RESULTSCompared with the torsion group, the treated mice showed significantly increased Johnsen score (5.00 +/- 1.85 vs 7.38 +/- 0.92, P < 0.05), seminiferous tubule diameter ([176.50 +/- 1.60]microm vs [178.75 +/- 1.58] microm, P > 0.05), spermatogenic cell layers (3.75 +/- 1.03 vs 5.75 +/- 0.71, P < 0.05) and SOD activity ([29.04 +/- 4.46] U/mg prot vs [52.67 +/- 3.57] U/mg prot, P < 0.05), but remarkably reduced level of MDA ([4.63 +/- 0.05] nmol/mg prot vs [2.91 +/- 0.04] nmol/mg prot, P < 0.05) and AI of germ cells ([40.50 +/- 1.60]% vs [16.25 +/- 1.67] %, P < 0.05).

CONCLUSIONGrape seed proanthocyanidin has a protective effect against spermatogenic injury in mice, the mechanisms of which may be related to its actions of scavenging oxygen free radicals, inhibiting lipid peroxidation and improving the antioxidant ability of the body.

OBJECTIVETo investigate the effects and mechanisms of hawthorn leaves flavonoids (HLF) on acute myocardial ischemia/reperfusion in anesthetized dogs.

METHODSThe acute ischemia models were prepared by ligating left anterior descending (LAD) artery for 60 min. Qualified 15 male dogs were randomly divided into 3 groups with 5 in each group: blank control (treated with normal saline 3 mL/kg) group, HLF low dosage (5 mg/kg) group and high dosage (10 mg/kg) group, with an once injection through a femoral vein 5 min before reperfusion. Epicardial electrocardiogram was adopted to measure the scope and degree of myocardial ischemia. Simultaneously, neutrophil infiltration in infarct (Inf) and remote site (RS) of myocardial tissue was measured by myeloperoxidase (MPO) activity assay. The serum interleukin-1 (IL-1) and tumor necrosis factorα (TNF-α) content were quantified by radioimmuno-assay. Furthermore, expression of G protein-coupled receptor kinase 2 (GRK2) and nuclear factor κB (NF-κB) in Inf and RS tissue were detected by Western blotting technique.

RESULTSIschemia and reperfusion increased the MPO activity and IL-1 and TNF-α content. HLF (10 and 5 mg/kg) could significantly decrease the degree and scope of myocardial ischemia; markedly inhibit the increase of MPO activity, and IL-1 and TNF-α content induced by myocardial ischemia/infarction. Furthermore, HLF increased GRK2 expression and inhibited NF-κB expression in Inf tissue.

CONCLUSIONHLF could improve the situation of acute myocardial ischemia and inhibit the inflammation in anesthetized dogs, which might be due to its increasing effect on the GRK2 and NF-κB expressions.

Variant pulmonary vein anatomy (PVA) has been reported to influence the recurrence of atrial fibrillation (AF) after radiofrequency ablation.However,the effects of PVA on AF in patients undergoing cryoballoon ablation (CBA) remain unknown.The present study aimed to examine the impact of PVA on the long-term outcome of CBA for AF.A total of 78 patients (mean age 60.7±10.9 years,64.1％ males) with symptomatic and drug-refractory paroxysmal AF were enrolled in the study.Left atrium (LA) and PVA acquired at computed tomography angiography (CTA) were reconstructed with CARTO(R) 3 SYSTEM.Patients were routinely evaluated by 24-hour Holter monitoring following CBA.Cox regression was used to detect the predictors of AF recurrence after CBA.The results showed abnormal PVA in 30 patients (38.5％) and 18 patients (23.1％) had left common PV (LCPV).Electrical pulmonary vein isolation was achieved in all patients.After a mean follow-up of 689.5±103.8 days,it was found that patients with abnormal PVA had similar AF recurrence rate to those with normal PVA (26.7％ vs.25.0％,P=0.54),and there was no significant difference in AF recurrence rate between LCPV patients and non-LCPV patients (33.7％ vs.23.3％,P=0.29).Cox regression analysis showed that AF duration (72.9±9.0 vs.42.3±43.2 months,HR 1.001;95％CI 1.003-1.014;P＜0.001) and cryo-applications of right-side PVs (3.0±1.6 vs.4.7±1.7,HR 0.661;95％ CI 0.473-0.925;P=0.016) were independent predictors of freedom from AF,but PVA was not identified as a predictor of long-term success.In conclusion,the variant PVA cannot significantly influence the long-term outcome of AF patients undergoing CBA;longer AF duration and less cryo-applications of right-side PVs are associated with higher AF recurrent rate.
