Dilatative arteriopathy is also called Dolichoectasia, presenting as enlarged ,tortuous ,and dilated arteries; especially with involvement of intracranial arteries. The incidence of dolichoectasia is quite low, but it may induce recurrent strokes with poor prognosis and up to now there is no specific management. Our study reviews the potential etiology, epidemiology, symptoms, pathophysiology, prognosis and present status of treatment for dolichoectasia.

Endovascular coil embolization is the first primary technique of choice for treating intracranial aneurysms in many centers around the world ,but some patients still got recanalizations months later,that may lead to death or severe disability just as the same in neurosurgery. This review showed the technic details of the first generation of Matrix bioabsorbable poly-meric material coil ,and analyzed clinical results among many treatment centers,involving the therapeutic measure of intracranial aneurysms.

Objective To analyze the clinicopathologic factors related to the prognosis of gallbladder carcinoma.Methods A retrospective analysis was conducted on 61 cases of advanced gallbladder carcinoma who were operated on from 2001 to 2006 in Nanjing First Hospital.Results According to the 6th UICC/AJCC TNM classification and staging of gallbladder carcinoma,of the 61 patients,8 patients were stage IB,22 were IIA,11 were IIB,14 were III and 6 were IV.Palliative cholecystectomy and/or bile duct drainage procedures were performed in 24 patients;removal of gallbladder plus regional lymph nodes and fatty tissue dissections were performed in 14 cases;radical resection was performed in 7 patients;removal of gallbladder and part of liver in combination with resection of bile duct(radical operatian) was performed in 13 patients;1 patient had extensive radical operation including pancreaticoduodenectomy.In 37 patients,18 had positive lymph node metastasis.Fifty-two patients were followed up,41(67.2%) patients were alive at 6 months after operation,26(42.6%)were alive at 12 months,10(16.4%) were alive at 24 months,and 7 cases were alive at 36 months,1 patient is still alive 5 years after operation;51 patients died within 2 years after operation.The symptoms of recurrence in 31 patients included progressing jaundice(21 cases),metastasis in liver(14 cases),and refractory ascites(12 cases).Five patients died of non-bile duct disease.Conclusions The prognosis of gallbladder cancer has a close relationship with the clinical stage and method of resection.

Objective To investigate the production of reactive oxygen species and anti-oxidative protein of neutrophils in patients with coronary heart disease, and to evaluate the role of neutrophil activation in the pathogenesis of coronary heart disease. Methods Reactive oxygen species production was measured by chemiluminescence method, the degranulation of neutrophils was detected by the whole cell patch-clamp capacitance technique, the plasma and intracellular levels of myeloperoxidase(MPO) were quantified by photometry.Results The production of superoxide anion in neutrophils was increased in patients with stable or unstable angina more significantly than control group (344.21?64.4,325.65?65.1 vs 271.53?56.2,P

Objective To evaluate the value of brain natriuretic peptide(BNP) in estimating risk stratification in patients with acute myocardial infarction(AMI) and to determine the relationship between BNP and adverse cardiac events after AMI.Methods The 135 subjects were selected into the study including 25 healthy subjects and 110 patients with a first AMI.The plasma concentrations of BNP were measured at two to four days after infarction in patients and healthy controls.Left ventricular function was evaluated by echocardiography with the parameters of left ventricular ejection function(LVEF) after 3 months.Patients were followed up at 12 months.The main outcome measures were heart failure,left remodeling mortality and other adverse cardiac events at one year.Results Plasma BNP concentrations in patients with AMI were much higher than those in the health control people[(416.7?208.0)ng/L versus (61.8?34.1)ng/L,P400ng/L,P=0.019).Plasma BNP concentrations remained associated with the development of clinical end points in multivariable model that adjusted for potential confounding variables.Conclusion The results of the present study confirm that the elevated BNP count related to the risk stratification and prognosis in patients with AMI elevations in BNP count is associated with a higher incidence of new CHF and adverse clinical outcomes after AMI it could serve as s strong predictor for the subsequent development of poor outcomes in AMI patients.

Objective To investigate the relationship between Atherogenic Index of Plasma(AIP) and the dorsalis pedis artery atherosclerosis in type 2 diabetes. Methods One hundred and twenty-seven patients with type 2 diabetes and 33 healthy individuals were included in the study. The diabetic patients were devided into 2 groups, with( n = 66) or without ( n = 61 ) atherosclerosis. The intima media thickness (IMT) of dorsalis pedis artery were measured by B-mode Doppler ultrasonography. The triglyceride(TG) ,high density lipoproteincholesterol(HDL-C) and other glucolipid metabolic indices were measured in all patients. The AIP was defined as the log value of TG/HDL-C ratio. The one-way ANOVA test was performed to determine the differences among three groups. The relationships between IMT and the other indicators were assessed using Pearson bivariate correlations analysis. The optimal operating point of AIP to diagnose the dorsalis pedis artery atherosclerosis in type 2 diabetes was obtained by drawing ROC curve. Results The AIP value in atherosclerosis diabetic patients,no-atherosclerosis diabetic patients and healthy subjects were 0. 229 ± 0. 132,0. 112 ± 0. 074 and -0. 045 ± 0. 033 respectively. The IMT value were (0. 71 ± 0. 24 ) mm, (0. 49 ± 0. 09 ) mm and (0. 34 ± 0. 15 ) mm respectively. Both indices shown statistical differences among the three groups (Ps = 0. 001 respectively). After adjusting for potential influence factors, AIP showed positive correlation with IMT( r = 0. 315, P = 0. 001 ). The OOP of AIP was 0. 1671 ,the area under the curve was 0. 783. Conclusion AIP was well related to the dorsalis pedis artery atherosclerosis in type 2 diabetes,and the OOP of AIP had good diagnostic reference value in these patients.

Objective To evaluate the value of CT in diagnosing primary small intestinal lymphoma. Methods CT features of 11 cases of primary small intestinal non Hodgkin′s lymphomas were retrospectively analyzed. Results The most frequent location of the diseases were at ileum (10/11). According to the main CT features from all 11 cases, it could be classified into two types: bowel wall thickening type ( n =7) and luminal polypoid mass type ( n =4). 5 of 7 cases in the first type showed aneurysmal sign, while 3 of 4 cases in the second type were combined with intussusception. 7 cases from the two types were found to have mesenteric lymph nodes enlargement, among them 1 case showed “sandwich” sign, 4 showed long range or multicentric intestinal lesions. The tumor detection rate was 81.8%, and the correct diagnosis rate was 63.6% by CT. Conclusion Bowel wall thickening and luminal polypoid mass were two different types of CT features in the primary small intestinal lymphoma, and polymorphic lesions accompanied by multifocal mesenteric lymph nodes enlargement, aneurysmal sign, “sandwich” sign, long range or multicentric intestine lesions were the main characteristic CT features, which may lead to the correct diagnosis by CT.

Objective To investigate the linkage between the mutation of IL 4R ? chain gene and susceptibility of asthma and atopy in Wuhan. Methods Thirty five samples from asthmatic children,twenty five samples from adult patients with asthma, twenty samples from health adult and children respectively, were analyzed. A coding region 1205 1928 of IL 4R ? chain gene was detected by reverse transcription polymerase chain reaction/Single Strand conformation polymorphism/Sequence. Result 57.8% cases from asthmatic children, one polymorphism (1902 A→G), were found exist in the IL 4R ? chain gene and only 8% cases from asthmatic adults and 5% cases from control have this mutation. Conclusion The SNP of IL 4R ? chain coding area 1902 correlates with susceptibility of asthma in Wuhan asthmatic children (? 2=12.54, P 0.05, ?=0.05). There may be another mutations in IL 4R ? chain coding area except 1902 or another changes in other gene related with allergy.

Objective To establish a rat model of chronic atrophic gastritis and investigate the factors inducing gastric atrophy. Methods According to the repeated orthogonal design of L 8(2 7), 60% alcohol and 20 mmol/L sodium deoxycholate (served as factor A), 0.05%～0.1% ammonia water (factor B) and 0.05% indomethacin (factor C) were given, alone or in combination, to rats in three experiments for 3 months, 6 months and 9 months, respectively. Then the rats were sacrificed and pathologic changes of the gastric mucosa were studied by gross appearence and microscopy. Results Typical appearance of CAG, which could maintain over one month, were found in all rats treated with factor A,B,C alone or in combination for 6 or 9 months. Conclusion 60% alcohol, 20 mmol/L sodium deoxycholate, 0.05%～0.1% ammonia water and 0.05% indomethacin given to SD rats for 6 months could establish animal model of CAG with a 100% successful rate.
