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.

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.

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.

Objective To investigate the influences of the genetic factors on the plasma homocysteine (Hcy) level, and the relationships between the plasma homocysteine levels and the polymorphisms in 5,10-methylenetetrahydrofolate reductase (MTHFR) and cystathionine ?-synthase (CBS) and the cerebral infarction. Methods All 87 patients with acute cerebral thrombosis and 80 controls were studied. Plasma Hcy levels were measured by high-performance liquid chromatography-fluorescence detection(HPLC-FD)from using baseline 810 high-performance liquid chromatograph. The presence of the MTHFR C677T mutation was determined by polymerase chain reaction (PCR) assay and subsequent restriction enzyme digestion, and the presence of the CBS G919A or CBS T833C was determined by amplification refractory mutation system. Results Fast plasma Hcy levels were shown higher in the patient group (15.3?4.3) ?mol/L as compared with those in the control group (11.3?3.9) ?mol/L (P

Objective To explore medical equipment allocation with considerations on randomly distributed and dynamic injury conditions by analyzing injury conditions transition and medical equipment stochastic service process.Methods A casualty array change model was established by injury conditions evolution analysis,Poisson process and Markov chain.Medical equipment stochastic service processes in medical facilities were probed,and the service rules were constructed.Expert investigation was carried out to acquire conditions transition indexes and to determine the vectors for conditions transition without manual intervention and their changes after treatment,then simulation tools were used to optimize medical equipment allocation.Results The emergency treatment table in some field medical station was considered as the subject,and the optimum allocation was proposed for emergency treatment table with practical data and simulation calculation.Conclusion The emergency treatment table allocation proposed was similar to the actual one in the medical station.Markov-process-based medical equipment allocation responses injury conditions changes and the fluctuation of treatment sequence,which has the result reliable and the method versatile and practical,and lays a foundation for medical equipment allocation and optimization.
