Objective To identify the causes of coronary angiographic hazy lesions by intravascular ultrasound (IVUS) to avoid inappropriate stenting. Methods Twenty-five cases with hazy regions on coronary angiogram were consecutively identified from July 2009 to March 2010. Hazy regions were defined by coronary arteriongraphy as reduced contrast density without a clearly defined intimal tear, dissection,thrombus,or stenosis ( ＞ 50% ). This cohort of patients were subsequently underwent IVUS examinations and treated according to the results of IVUS. Results The lumen CSAs were settled as ＞ 4. 0 mm2 in all examinations. Among all 25 cases,hazy lesions were located in left anterior descending in 12 patients, right coronary artery in 6 patients, left circumflex in 5 patients, and left main artery in 2 patients. According to the IVUS findings, 2 cases showed absolutely normal or near-normal arterial wall structure image, 10 cases showed calcified plaque,5 cases showed plaque rupture,3 cases showed eccentric plaque ,2 cases showed thrombosis formation,2cases showed dissection,1 case showed subintimal hematoma. Seven patients received stent implantation, and the rest accepted medical therapy. There were no in-hospital MACEs reported among all patients. Conclusion Nearly half of the coronary arteriongraphic hazy lesions were caused by calcified plaque. IVUS can distinguish calcified plaques from intimal tears, thrombus and other underlying etiologies,and help to avoid unnecessary stenting.

Tumor cells obtain energy mainly by glycolysis to maintain growth and proliferation. It is related to the DNA mutations of mitochondria and anti-oncogene mutations. Inhibition of glycolysis can inhibit proliferation and kill tumor cells. The rate-limiting enzyme of glycolysis and hypoxia inducible factor may be the new targets for cancer therapy.

56 school-aged children with epilepsy and 37 normal ones of the same gender,age and educational level were selected. All the subjects' parents completed the child adaptive behavior scale, the mutiple stepwise linear re-gression was used to explore the impact of epilepsy related factors on social adaptive function. The social adaptive function of school-aged children with epilepsy faulty is affected by seizure frequence,gender,age,epilepsy control, clinical course,and the number of antiepileptic drugs.

Objective To investigate the risk factors of in-stent restenosis (ISR) after coronary implantation of drug-eluting stent Methods One hundred and fifty-seven patients including 118 males and 39 females,who underwent successful implantation of drug-eluting stent, were recruited in the study. The patients were divided into the restenosis group (33 patients) and non-restenosis group ( 124 patients) according to the angiographic results. The associations of ISR with clinical and coronary angiographic characteristics were analyzed using univiriate analysis and logistic regression. Results In the restenosis group,there were 18 cases of diabetes mellitus ( 54. 5% ), 26 cases of frequency angina ( 78. 8% ), which were significantly higher than those of 31 cases of diabetes (25.0%) and 72 case of frequent angina (58. 1% ) in the non-restenosis group (χ2 = 10. 60, P ＜ 0. 01, χ2 = 4. 77, P = 0. 03 for diabetes mellitus and frequent angina, respectively). Compared to non-restenosis group, the occurrence rates of chronic total occasion, bifurcatus lesions, diffuse lesions were significandy higher in the restenosis group ( 19. 3% vs 7. 6% χ2 =5.92,21.1% vs 10. 2% χ2 =4. 34,26. 3%vs 12. 1% χ2 =6. 32,Ps ＜0. 05). Fifty-seven stents were implanted into the restenosis group,and one hundred and fifty-seven into the non-restenosis group. Logistic regression analysis showed that diabetes, frequent angina,chronic total occlusion lesions, bifurcatus lesions, diffuse lesions, stent length and diameter were significantly associated with restenosis ( OR value were 3.52,2. 59,3.05,3. 14,3.08,0. 93,95% CI were 1.56 - 7.90,1.02 - 6. 59,1.11 - 8. 36,1.30 - 7.59,1.34 - 7.05,0. 88 - 0. 98 respectively, Ps ＜ 0. 05 ). Conclusion After implantation of drug-eluting stent, diabetes mellitus, chronic total occasion lesions, frequent angina, diffuse lesions, bifurcatus lesions and stent length and diameter are associated with follow-up restenosis.

Objective To evaluate the safety and effectiveness of treating the endovascular stents placement for spontaneous isolated dissection of splanchnic artery ( SIDSA).Methods Sixteen consecutive patients with diagnosis of SIDSA through CTA and DSA were retrospectively analyzed .All patients had acute persistent abdominal pain and treated by endovascular stents placement.The serious complications and symptoms improvement were reviewed after the operation.The symptoms recurrence and repeated color doppler ultrasonography and CTA were also reviewed in the follow up.Results Twelve superior mesenteric artery ( SMA) dissection and four celiac artery ( CA) dissection were diagnosed among sixteen patients.The dissection length was 1.07 to 11.87 cm and the median length was 3.93 cm.The distance from the original dissection to the orifice of superior mesenteric artery or celiac artery was 0.50 to 6.44 cm and the median was 1.98 cm.Eight stent-grafts and 3 bare stents were successfully implanted in 11 patients.One case with celiac dissection was failed to treat because of the severe compression of true lumen and the guide wire cann′t cannulate to the distal true lumen.Four patients with superior mesenteric artery dissection gave up interventional therapy , Among these 4 patients , 2 patients had small tear site and small false lumen , 1 patient had extremely long dissection , and one case had blood supply of target organs from both true and false lumen.No severe complications such as hemorrhage , intestinal necrosis , hepatic failure and splenic necrosis occurred during the eleven successful endovascular interventions.The abdominal pain in 10 cases was disappeared or significantly relieved , 1 case with superior mesenteric vein thrombosis and severe intestinal ischemia before intervention underwent intestinal resection for necrosis.The follow up period was 1 to 74 months in eleven successful cases , and the median follow-up period was 16 months.One patient with SMA dissection after endovascular treatment was died of sudden stroke three months later .Others had satisfactory outcome and the repeated color doppler ultrasonography and CTA were normal .Conclusions Endovascular stents placement is a safe and effective therapy for symptomatic spontaneous isolated dissection of splanchnic artery.

BACKGROUND: Caspase family is viewed as the executive factor of cell apoptosis. Neuronal apoptosis happens probably after spinal cord injury.OBJECTIVE: To observe the changes in caspase-3 expression after spinal cord injury in rats so as to probe into the relationship between it and neuronal apoptosis and provide the evidence on the prop e r time window of intervention on alleviating secondary spinal cord injury.DESIGN: Self-control and mutual-control were designed in animal experiment.SETTING: Department of Traumatic Surgery and Department of Orthopedics of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology.MATERIALS: The experiment was performed in Experiment Room of Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology from January to December 2001, in which, 54SD rats were employed, of either sex, mass weighted varied from 220 to 250 g and provided from Animal Experimental Center of Tongji Medical College of Huazhong University of Science and Technology.rats were divided into the control and injury group. Laminectomy was only done on Ts and T9 in the control and the injury group was subdivided into 9 subgroups, in which, the materials were collected on the 4th and 8th hours and on the 1st, 2rd, 3rd, 7th 14th and 21st days successively, 6 rats in each one. After abdominal anesthesia with 30 g/L pentobarbitol sodium,sternal cord on T8 andT9 segments were exposed with Nystrom method and 50 g weight compressed the front middle region of the spinal cord of such segments with arch smooth metal pad 2.2 mn×5.0 mm for 5 minutes. After injury, artificial bladder urination was done 3 times at 10:00, 16:00and 22:00 successively everyday till the bladder reflex was established.cord was collected at various time spots after spinal cord injury. 4 pieces of spinal cord tissue masses from each group, about 8mm in length, were embedded with paraffin and sectioned continuously. Afterwards, HE staining, immunohistocheistry and TUNEL (TdT-mediated dUTP-biotin nick end labeling) were performed successively. Two rats were sacrificed on ice in each group and central tissue of injured spinal cord was placed in expression was assayed with immunohistochemistry method, neuronal apoptosis was assayed with TUNEL method and linear correlation was used to analyze the correlativity between caspase-3 expression and neuronal apoptosis.pase-3 expression after spinal cord injury in rats of each group.RESULTS: Six rats were maintained in each group and included in result optic microscope: Extensive hemorrhage appeared in 1 hour in injured segment. In 4 to 8 hours, spinal structure began destructive and a large amount of neuronal death appeared. In 24 hours, the destruction of spinal cord became severe and in 7 to 21days, the range of injury was defined with immunohistochemistry in rats of each group: Very few caspase-3 expressions (2.1±0.5) presented in neurons of spinal cord in normal rat. In 8hoursafter spinal cord injury, caspase-3 expression of positive neurons was increased remarkably (89.2±10.5) and up to the peak (189.6±12.7) in 3 days. Caspase-3 expression of positive cell and apoptotic cell appeared alexpression assayed with transcription-polymerase chain reaction (RT-PCR)in rats of each group: Caspese-3 mRNA (0.442±0.024) began increased in 4h, was up to the peak (0.634±0.028) in 48 hours and was restored to be normal (0.351±0.013) in 7 days, which appeared early than apoptosis, indicating positive correlation with the level of neuronal apoptosis (r=0.622).In the control and 4 hours group, stained cell was seen occasionally and positive cell appeared 8 hours later, mainly localized in gray matter. Afterwards, positive cell was increased and up to the peak in 3 days. In 7 days,positive cell of apoptosis and staining was decreased gradually in gray matter, mainly around the white matter. Little amount positive cells appeared on the 14th day and 21st day.CONCLUSION: In normal spinal cord tissue, caspase-3 existed in form of zymogen with very low activity. Caspase-3 is enhanced in expression after spinal cord injury in rats, expresses in large amount in 8 hours and is up to the peak in 24 to 48 hours, which is overlapped in time with positive apoptotic cell assayed with TUNEL and concerning to the localization, it is in conformity with positive apoptotic cell of spinal cord injury compared with positive cell of caspase-3. It is indicated that caspase-3 is involved in regulation of cell apoptosis after spinal cord injury. It is seen in this experiment that the time from spinal cord injury to the activation of caspase-3 is the time window of treatment for cell apoptosis intervened by spinal cord and alleviating secondary spinal cord injury. It is suggested that genetic intervention or specific caspase-3 inhibitor should be applied in 48 hours.

Objective To study the diagnostic value of porphobilin staining of gastric mucus for primary pathologic duodenogastric reflux (DGR). Methods A total of 58 DGR patients diagnosed from January, 2007 to April, 2008 were recruited to the study as DGR group, and 21 healthy volunteers as control.All subjects underwent 24-hour intragastric bilirubin monitor and gastroscopy. Bilirubin absorption value of 0. 25 and median reflux time of 23.60% were taken as thresholds to differentiate low reflux group ( reflux time ＜ 23.60% ) and high reflux group (reflux time ≥23.60% ). Porphobilin staining of gastric mucosa was quantitatively analyzed. Results Deposition of porphobilin in mucosa of gastric antrum, gastric angle and gastric body in primary pathologi DGR group was significantly higher than those in healthy group (P ＜0. 05 ). The occurrence of atrophic and intestinal metaplasia of gastric antrum in high reflux group was significantly higher than that of low reflux group (P ＜ 0. 05). Deposition of porphobilin in mucosa of gastric antrum, gastric angle and gastric body in high reflux group was significantly higher than that of low reflux group (P ＜ 0. 05 ). The New Sydney system pathological scores of gastric antrum and angle of high reflux group was higher than that of low reflux group ( P ＜ 0. 05 ). The deposition of porphobilin in mucosa of gastric antrum and gastric angle was positively correlated with New Sydney system pathological scores in primary pathological DGR group (r=0.59, P=0.041 andr=0.73, P=0.038). Conclusion Porphobilin staining of mucosa in gastric antrum can reflect the severity of bile reflux, and is positively correlated with the extent of gastric mucosal lesion, which may be helpful in diagnosis of primary pathological DGR.
