Objective:To investigate the complications of using central venous catheters ports.Methods:From March 2005 to September 2008,103 patients under the fluoroscopy were placed with central venous catheters port through the right subclavian vein puncture.The reasons of complications were retrospectively analyzed and managements were explored.Results:Among the 103 patients,101 cases were successfully implantated.The technical success rate was 98.06%(101/103).The complications were 19 cases(18.45%,19/103).Conclusion:Improved perioperative management and strengthening the clinical nursing can effectively reduce the incidence of complication of central venous cathethers ports.

Objective To discuss the correlative factors affecting the short-term prognosis in treating malignant obstructive jaundice with percutaneous transhepatie biliary drainage (PTBD) and/or percutaneous transhepatic biliary stenting (PTBS). Methods During the period of December 2008-June 2009, PTBD and/or PTBS were performed in 67 patients. The clinical date were reviewed and analyzed. According to the reduction degree of serum bilirubin and survival condition in 30 days, the patients were divided into effective group (54 cases) and ineffective group (13 cases). Single factor affecting the short-term prognosis was analyzed by using X~2 test and multi-factors were analyzed by using non-conditional logistic regression mode. Results Single variable analysis showed that time of obstruction, way of drainage, preoperative biliary infection, Child-Pugh grade, TBIL, HGB and Cr level were of statistical significance. The logistic regression analysis showed that there were obvious correlation among preoperative biliary infection, Child-grade ≥ 11 and Cr > 115 μmol/L. Conclusion The infection of the bile duct before operation, Child-grade ≥ 11 and Cr >115μmol/L carry a close relationship with the short-term prognosis of PTBD and PTBS. Therefore, an overall preoperative evaluation for malignant obstructive jaundice is of great importance.

Atrial fibrillation (AF)is a strong risk factor for ischemic cerebral stroke.Some inherent defects of War-farin limit its clinic application,which accelerates research and development of new oral anticoagulants,such as Dabigatran,Apixaban,Rivaroxaban and Edoxaban etc..This article made an overview for these.

0.05).No significant difference was shown among the four groups for the proportions of brainstem involved(P=0.335).Significant differences were found for the proportions of bilateral hemicerebrum and spinal cord involved(P

Objective To explore the relationship between plasma homocysteine(Hcy) levels and cerebral infarction.Methods 87 patients with acute cerebral infarction and 80 controls were enrolled in the study. Plasma Hcy levels were measured by high-performance liquid chromatography-fluorescence detection(HPLC-FD) technology using Baseling 810 type high-performance liquid chromatograph.Results Fast plasma Hcy levels were higher in the patient group[(15.28?4.33)?mol/L] compared with those in the control group[(11.32?3.86) ?mol/L]( P

Objective To study the relationship of plasma homocysteine (Hcy), polymorphism in 5,10-methylenetetrahydrofolate reductase (MTHFR) and cystathionine-?-synthase (CBS) genes, and cerebral infarction in the elderly. Methods 61 elderly patients with first-ever acute cerebral infarction and 57 controls were studied. The plasma Hcy levels were measured using high-performance liquid chromatography-fluorescence detection (HPLC-FD). The polymorphism in MTHFR was determined by a polymerase chain reaction (PCR) assay and subsequent restriction enzyme digestion.CBS was determined by amplification refractory mutation system (ARMS). Results The fast plasma Hcy levels were higher in the patient group compared with those in the control group [(13.07?3.96)?mol/L vs (11.51?3.90)?mol/L, P 0.05). There were no differences in the plasma Hcy levels among the different genotypes. Conclusions The MTHFR, CBS gene mutations cannot lead to hyperhomocysteinemia in the elderly patients with acute cerebral infarction. Hyperhomocysteinemia is associated with the independent risk of cerebral infarction, however, mutations only in MTHFR and CBS cannot be ascertained to be independent risk of cerebral infarction in the elderly.

Objective To investigate the diagnostic value of HLA-B27 in ankylosing spondylitis(AS).Methods A diagnostic test was employed in the study.The patients with ankylosing spondylitis and the controls in Shandong Provicial Hospital from 2001—2005 were enrolled in the study.HLA-B27 was detected by flow cytometer assay when recruited.SPSS 13.0 was used for statistical analysis.Results Totally 133 patients with AS and 88 controls were available in the study.HLA-B27 was significantly different between AS group and the controls(P=0.000).The areas below ROC curve was 90.5%.Three cut-off points of HLA-B27,11.55%,46.6% and 85.25%,were selected based on clinical practice and ROCcurve,and the sensitivity was 94.7%,90.2% and 63.6%,the specificity was 56.8%,92.0% and 95.45%.Conclusion HLA-B27 which is more than 46.6% is a valuable marker for the diagnosis of AS.

Objective To analyze the relationship between diabetics and the onset, clinical outcomes and prognosis of brainstem infarction, and to evaluate the impact of diabetes on brainstem infarction. Method Compare 172 cases of acute brainstem infarction in patients with or without diabetes.Analyze the associated risk factors of patients with brain-stem infarction in diabetics by multi-variate logistic regression analysis. Compare the National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin scale (mRS) Score, pathogenetic condition and the outcome of the two groups in different times. Results The systolic blood pressure ( SBP ), TG, LDL-C, apolipoprotein B ( Apo B ), glutamyl transpeptidase (γ-GT), fibrinogen(Fb), fasting blood glucose (FPG) and glycosylated hemoglobin( HbA1c)in diabetic group were higher than those in non-diabetic group , which was statistically significant ( P ＜ 0. 05 ). From multi-variate logistic regression analysis, γ-GT, Apo B and FPG were the risk predictors of diabetes with brainstem infarction( OR = 1. 017, 4. 667 and 3. 173, respectively), while HDL-C was protective( OR =0. 288). HbA1c was a risk predictor of severity for acute brainstem infarction( OR = 1. 299), while Apo A was beneficial( OR =0. 212). Compared with brain-stem infarction in non-diabetic group, NIHSS score and intensive care therapy of diabetic groups on the admission had no statistically significance, while the NIHSS score on discharge and the outcome at 6 months' of follow-up were statistically significant. Conclusions Diabetes is closely associated with brainstem infarction. Brainstem infarction with diabetes cause more rapid progression, poorer prognosis, higher rates of mortality as well as disability and higher recurrence rate of cerebral infarction.

Objective To explore the clinical significance of retrograde access for the interventional treatment of lower extremity arterial occlusive diseases when the occluded segment of lower extremity artery could not be reached through antegrade access.Methods Twenty-seven cases (male 17,female 10; age range 32-89 years ) were retrospectively investigated, including 18 with lower limb arteriosclerosis obliterans,7 with diabetic foot and 2 with thromboangiitis obliterans.According to the Fontaine staging,6 cases were classified as Fontaine Ⅱ,11were classified as Fontaine Ⅲ and 10 were classified as Fontaine Ⅳ.All cases underwent endovascular operation through antegrade access first with an attempt to cross the occlusive segment,but in vain.So retrograde access was tried via puncture of pedis dorsalis or posterior tibial artery or exposure of lateral branches of posterior tibial artery,peroneal artery or dorsal artery by open surgery,which followed by Percutaneous transluminal angiography and (or) stenting.Results The operation through retrograde access was successful in all cases with obvious improvement of ischemic symptoms.Hematoma at the puncture site occurred in 3 patients,and paresthesia of toes occurred in 1after dorsalis pedis arteriotomy.No severe perioperative complication occurred.The average ankle brachial index increased from 0.37 ± 0.11preoperatively to 0.85 ± 0.12 postoperatively.Conclusions Retrograde access could be used as an alternative strategy in lower extremity arterial occlusive diseases when the occluded segment could not reach through antegrade access.

Objective To investigate the correlation between diabetes and brainstem infarction. Methods The diagnozed patients with acute cerebral infarction were recruited in the study. Firstly, they were divided into brainstem infarction group and non-brainstem infarction group, and then they were redivided into brainstem infarction with diabetes, brainstem infarction without diabetes, non-brainstem infarction with diabetes and non-brainstem infarction without diabetes groups according to whether they had diabetes or not. Carotid artery intima-media thickness (IMT) and carotid atherosclerosis were detected and identified with Doppler ultrasound; brain stem infarction and its location were identified with diffusion-weighted imaging; basilar artery atherosclerosis was detected with magnetic resonance angiography (MRA). A multivariate logistic regression analysis was used to screen the different risk factors impacting brainstem infarction. Neurological deficit was evaluated with the modified Rankin Scale (mRS)scores. Results A total of 286 patients with acute cerebral infarction were recruited: brain stem infarction in 63, and 34 of them with diabetes; non-brain stem infarction in 223, and 77 of them with diabetes. The proportions of diabetes (54. 0％ vs. 34. 5%, x2 = 7. 816, P = 0. 005),previous cerebral infarction (38. 1％ vs. 24. 2％ ,x2 =4. 771, P =0. 029), basilar artery atherosclerosis (73.0％ vs. 57. 4％,x2 =5. 028, P =0. 025), as wall as the levels of hemoglobin A1C (HbA1c) (7. 30 ± 2. 42％ vs. 6. 46 ± 1.82％, t = - 2. 531, P = 0. 011 ) and apolipoprotein B (ApoB) (0. 97 ± 0. 33 mmol/L vs. 0. 90 ± 0. 34 mmol/L, t =-2. 180, P = 0. 029) in the brainstem infarction group were significantly higher than those in the non-brainstem infarction group. Multivariate logistic regression analysis showed that diabetes (odds ratio [ OR] 2. 150, 95％confidence interval [ CI] 1. 214-3. 808; P =0. 009) and previous cerebral infarction (OR 1. 835, 95％ CI 1.004-3. 352, P = 0. 048) were the independent risk factors for brainstem infarction. There were significant differences in the levels of HbA1c (P ＜ 0. 001 ), fasting blood glucose (FBG) (P ＜0. 001), ApoB (P =0. 007) and high-density lipoprotein cholesterol (P =0. 018) as well as the proportion of basilar artery atherosclerosis (P = 0. 001 ) among the brainstem infarction with diabetes, without diabetes, non-brainstem infarction with diabetes and without diabetes groups. The levels of HbA1c (8. 81 ±2. 36％), FBG (8. 23 ±3. 12 mmol/L andApoB (1.04 ± 0. 41 mmol/L) as well as the proportion of basilar artery atherosclerosis (85. 3％ )were the highest in the brainstem infarction with diabetes group. Conclusions Diabetes is closely associated with brainstem infarction. Diabetes is more likely to result in pontine infarction.
