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.

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 understand the status of Ascaris eggs pollution in soil at national monitoring spots of soil-transmit-ted nematodiasis,so as to provide the evidence for making countermeasures and evaluating the control effect. Methods Ten households were selected from each of the 22 national monitoring spots annually according to the National Surveillance Program of Soil-Transmitted Nematodiasis(Trial),and the soil samples from vegetable gardens,toilet periphery,courtyards and kitchens were collected and examined by using the modified floatation test with saturated sodium nitrate. Fertilized or unfertilized eggs as well as live or dead fertilized eggs were discriminated and identified. In addition,a SWOT analysis of monitoring of Ascaris eggs pollution in the soil of rural China was carried out. Results A total of 1 090 households were monitored in 22 monitoring spots from 2006 to 2010. The total detection rate of Ascaris eggs in the soil was 30.73%,and the detection rates of fertilized,unfertilized and live fertilized eggs were 13.21%,26.42%and 20.28%,respectively. The total detection rates of Ascaris eggs in the vegetable garden,toilet periphery,courtyard and kitchen were 16.51%,13.49%,14.22% and 10.73% respectively. The SWOT analysis demonstrated that the monitoring work had both advantages and disadvantages,and was faced with opportunities as well as threats. Conclusion The pollution status of Ascaris eggs in the soil is still quite severe at some national monitoring spots,and the counter-measures such as implementing hazard-free treatment of stool,improving water supply and sanitation and reforming environment should be taken to protect people from being infected.

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 investigate the effect of a dual regulation of replicating adenovirus vector carrying human endostatin gene (AdTPHre-hEndo) on pancreatic cancer. Methods Human endostatin (hEndo) gene was cloned into the genome of replicating adenovirus specific for the tumor cells by virus recombination technology. The virus titer was 3.25 × 1010pfu/ml. A Balb/c nude mouse model carring sw1990 cells pancreatic cancer was established, the expression of human endostain and inhibition of tumor cells in vivo were detected. Results We successfully constructed AdTPHre-hEndo. The inhibition on pancreatic cancer cell line SW-1990 of AdTPHre-hEndo is better than Ad-hEndo (P ＜0. 01 ), and ONYX-015 ( P ＜ 0. 05 ). The endostatin expression of AdTPHre-hEndo group was significantly higher than Ad-hEndo group and the control group (P ＜ 0. 01 ). The intratumoral MVD also decreased significantly in the treated tumors(6. 8 ±2. 5 vs. 16. 0 ±4. 6、47. 2 ± 10. 0, P ＜0. 01 ). Conclusions The recombination adenovirus can express biologically active hEndo effectively, which results in inhibiting the growth of micro-blood vessels and proliferation slowly.
