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 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 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 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.

Cerebral vasospasm is the main reasons of cerebral infarction and delayed ischemic neurological deficit in patients with spontaneous subarachnoid hemorrhage. At present, the research of cerebral vasospasm is relatively focused on the spasmogens in bloody cerebro-spinal fluid. This article reviews the mechanisms of cerebral vasospasm induced by the major spasmogens in the bloody cerebrospinal fluid after subarachnoid hemorrhage.

Background and purpose:For the past few years, HPV DNA has been detected in the peripheral blood in the patients with cervical cancer and believed to be a promising tumor marker, but because the concentration in the patients' serum was extremely low, it made it difficult to detect the circulating HPV DNA. In order to find a way to improve the sensitivity of the assay, this study compared and evaluated three methods that are currently being used to measure HPV DNA in the extraction from serum of cervical cancer patients. Methods:51 patients were pathologically proved to be cervical cancer and enrolled into the study. DNA from their sera was extracted by three methods:(1) Phenol-chloroform extraction, (2) UNIQ-10 collumn virus DNA kit(SANGON,Shanghai), (3) QIAamp MinElute Virus spin kit(QIAGEN,Germany). Then the HPV DNA was quantitated by PCR using GP5+/GP6+ primers.Results:Either fresh or short-term storage sera has been used The positive rates were 14.3%, 5.7%, and 57.1% with three assays, respectively. But when long-term storage samples were used to quantitate, the positive rates were low regardless of the methods being used.Conclusions:QIAamp MinElute Virus spin kit was the most sensitive for the content of serum HPV DNA, it could improve the positive rate for the assay if the serum was not stored for long time.

Human colostrum and milk collected at different times during the first six months of lactation from 301 subjects were tested for the levels of SIgA, IgM, IgG, C3, C4, lactoferrin and lysozyme by the technique of radial immunodiffusion. These kinds of immunoglobulins in colostrum and milk were detected, however the SIgA was highest among immunoglobulins in colostrum, which acounted for 89.8%.The average level of SigA on the first day of postpartum was 3152.5 mg/dl and exceeded those in the serum by 13-fold. It was suggested that breast-feeding may be crucial for the newborns before their mucosal immune system has been established. The average levels of C3 and C4 on the first day of postpartum were 99.7mg/dl and 65.9mg/dl respectively, reaching the normal serum level. Lactoferrin was as high as 1228.7mg/dl in the colostrum of the first day of lactation. The concentration of lysozyme was 944.2ug/ml on the first day of postpartum, which was about 429 times higher than that of cow milk. Using Holder pasteurization (62.5℃, 30 minutes), the SIgA and lysozyme activity of the milk could be reduced by 29.7% and 8.3% respectively, but a lot of anti-infective factors still remained in milk. So pasteurization may be useful for the sterilization of stored human milk.
