Objective To investigate the relationship between pathological types of intracoronary thrombus and changes of ST segment in patients with acute myocardial infarction. Methods Thrombus aspiration during primary PCI was performed in 65 ST-elevation myocardial infarction (STEMI) patients and 42 non-ST-elevation myocardial infarction (NSTEMI) patients. Pathological analysis on thrombosis was made. Results Thrombi characteristics were collected from 48 STEMI patients and 12 NSTEMI patients. In the STEMI group, 39(81.3%) red/mixed thrombus and 9(18.7%) white thrombus were found. While in the NSTEMI group, 8(66.7%) white thrombus and 4(33.3%) red/mixed thrombus were obtained. Conclusions There are both red/mixed and white thrombus in the two kinds of acute myocardial infarction. A variety of elements, including thrombus formation, could contributes to the change of ST in electrocardiograph during acute myocardial infarction.

Thrombin activated fibrinolysis inhibitor ( TAFI) is a kind of plasma enzymes that can be activated by thrombin.TAFI regulates blood coagulation and fibrinolysis and has a strong fibrinolytic and anti-inflammatory ac-tivity.Its inhibitor is expected to minimize the risk of bleeding when thrombolytic recanalization .Also, studies found that TAFI played an important role in the development of cerebral thrombosis;atherosclerosis and so on .

AIM: To study the effects of resveratral on lipid peroxidative reaction and reactive oxygen species (ROS) in experimental spinal cord injury rats. METHODS: The weight dropping method was used to produce the experimental spinal cord injury (SCI) in adult rats. Resveratrol (Res) and methylprednisolone (MPSS) were given intraperitoneally by the bolus injections of 50, 100 mg?kg -1 and 100 mg?kg -1 , respectively, immediately after induction of SCI. And then the effects of Res were observed at 1, 24, 48 h after SCI compared with MPSS. RESULTS: Res could obvious prevented reduction of superoxide dismutase (SOD) activity and reduce malondialdehyde (MDA) production and inhibit the ROS level in the injured spinal cord tissue in comparison with the SCI model at the dose of 50 mg?kg -1 and 100 mg?kg -1 , which the most remarkable effects was at 48 h with the inhibition rate over 40%. The effects of Res were the same as or even greater than those of MPSS. CONCLUSION: Res may effectively protect the spinal cord from lipid peroxidative reaction and ROS damage in SCI.

AIM To study the effects of resveratrol on secondary spinal cord edema and the activity of lactic dehydrogenase and Na +, K + ATPase in experimental spinal cord injury (SCI)rat. METHODS The weight dropping method was used to produce the experimental spinal cord injury in adult rats. Resveratrol (Res) and methylprednisolone (MPSS) were intraperitoneally by the bolus injections of 50 mg?kg -1 , 100 mg?kg -1 and 100 mg?kg -1 , respectively, immediately after the induction of SCI. And then the effects of Res were observed at 1 h, 24 h, 48 h after SCI compared with MPSS. RESULTS Res could obvious inhibit the secondary spinal cord edema with the most remarkable suppressing rate by 11 5% at 48 h. Res was able to significantly suppress the activities of the lactic dehydrogenase with the highest suppressing rate for over 40% at 24 h. In the meantime, Res markedly improved the Na +, K + ATPase activities that promoted to the biggest extent to 60% at 48 h. The effects of Res were the same as or even stronger than those of MPSS. CONCLUSION Res may effectively protect the spinal cord from secondary spinal cord edema and improve the energy metabolism system in SCI. It suggested that Res may be having potent therapeutic effect on SCI.

Objective To explore the typing,precaution and treatment of the bone cement leakage caused by percutaneous vertebroplasty(PVP).Methods PVP was performed in 38 cases(11 men and 27 women) with vertebral angioma and vertebral body compression fracture with osteoporosis chosen from November 2002.Results All the patients were followed up for 8 to 16 months and the effects were evaluated by the standards carried out by World Health Organization(WHO).The rate of complete response(CR) plus partial response(PR) was 100 percent.The patients with bone cement leakage by PVP were divided into 3 groups which underwent different remedial methods respectively.Conclusion The bone cement leakage could be prevented through the preoperative preparation,choosing the anaesthesia and scouting the whole operation.The patients with TypeⅠ,Ⅱ and Ⅲ_a needn't treatment,but those with type Ⅲ_b must accept open-operation.Vertebral eggshell technology with open vertebroplasty was effective on the treatment of the bone cement leakage with type Ⅲ_b caused by PVP.

The combination of transcranial magnetic stimulation and electroencephalogram (TMS-EEG) is an effective means for understanding the network of brain functions.The development of TMS-EEG,however,has been hampered by strong TMS-induced artifacts in the electrode leads.This article first introduces the TMS technology and expounds the causes of TMS-induced artifacts.According to the source of the artifact,the study reviews the artifact removing methods reported in the recent ten years regarding TMS discharge,muscle artifacts and auditory artifacts and residual artifacts.Perspectives of the related techniques are introduced at the end of the article.It is expectable that there will be a great breakthrough not only on the TMS theory but also in clinical research due to the attractive prospect in application and high research value of TMS.TMS-induced artifacts will be well solved at that time.

Obstructive sleep apnea syndrome (OSAS) is endangering human health seriously now. We had reviewed some typical animal model which had at least one OSAS character of intermittent hypoxia and/or hypercapnia, upper airway obstruction and sleep structure disorder. However, all of these models could not simulate clinical and pathological features of OSAS completely. Establishing a suitable animal model to study OSAS and related diseases is very important.

Objective To search the surgical methods of esophageal carcinoma complicated with cicatricial pyloric obstruction .Methods 18 cases were treated with resection. Among the resections,16 cases underwent resection of esophageal carcinoma esophago-gastrostomy above aortic arch in chest plus gastro-jejunum anastomosis ;2 cases treatment with resection of esophageal carcinoma plus esophago-gastretomy above aortic arch in chest combined with pyloroplasty.Results Of 18 cases ,cure rate was 100%.No severe complications were occurred in the procedure. Conclusion Surgical operation is safe , applicable and effective in treatment of esophageal carcinoma complicated with cicatricial pyloric obstruction.

Objective To evaluate clinical application of spiral CT portal vein (SCTP).Methods 110 patients with different hepatic diseases underwent SCT enhanced scan. The portal vain 3D images of different hepatic diseases were obtained with maximum intensity projection(MIP). Results SCTP could directly demonstrate the location and width of the portal and hepatic veins, detect the invasion and tumor thrombosis of portal vein.The degree of variation of portal vein was correlated to the grade of hepatic function. Conclusion SCTP has better clinical value. It can content requirement of clinic diagnosis.

Objective To approach the involved position and regulation as well as the clinical characteristics of hereditary multiple exostoses(HME).Methods One HME pedigrees including men and women 7 cases respectively confirmed clinically and pathologically was analysed.Results The most common location of exostoses was metaphysis of long bones.No exostoses was found in craniofacial bone.Conclusion There is no sex difference in the incidence of HME and the location of exostoses is mostly at metaphysis of long bones in this family.
