Objective Toexplore the findings of bile flow artifacts (BFA)on MR cholangiopancreatography(MRCP). MethodsEighty five patients with normal common bile duct (CBD)and 95 patients with dilated CBD who had MRCP examination were studied retrospectively. Findings of BFA on original thin images of MRCP were recorded. Date were tested by Chi-square test and Spearman ceefficient of rank correlation analysis. ResultsThe rate of BFA in CBD with normal group was 38. 8％ ( 33/85 ), in dilated group was 83.2％ (79/95), there was statistically significant difference between them( x2 ＝ 37. 512,P ＝ 0. 000). BFA was not observed when the diameter of CBD was no more than 4 mm. BFA was partly observed when the diameter of CBD was 4 mm ＜ ψ≤ 8 mm, single- string sign was predominant findings (52.6％ ,30/57 ). Three-string sign was predominant findings in CBD with slight-dilated group ( 85.7％,36/42). Multi-string sign was predominant findings in CBD with medium-dilated group (84. 6％, 22/26 ).There was statistically significant difference between each groups ( x2 ＝ 284. 561, P ＝ 0. 000 ).BFA had different manifestations with CBD of different diameter, there was relative between them ( r ＝ 0. 553, P ＝0. 000). ConclusionBFA can occur in CBD with normal diameter. CBD with dilated group has higher rate of BFA than CBD with normal diameter. Manifestations of BFA are relative with the diameter of CBD.

Objective To investigate the imaging characteristics of autoimmune pancreatitis (AIP)and its diagnostic value.Methods Imaging examinations and clinical data of 13 patients with AIP were reviewed retrospectively.Results All patients had enlargement of pancreas either diffusely ( n =11 ) or focally in pancreatic head ( n =2 ).The swollen pancreas was of homogeneous density on CT scan ( n =13 ),hypointense on T1-weighted images and mildly hyperintense on T2-weighted images in 4 patients.It was demonstrated as mild enhancement on artery phase of dynamic imaging and progressive enhancement on portal and delayed phase images.Capsule-like enhanced rim was presented around the pancreas in 9 patients.Stricture or obliteration of the common bile duct located in pancreatic head was found in 10 patients accompanied by intrahepatic bile duct dilation.Pancreatic duct was invisible on axial images in 11 cases.Among the 6 patients underwent MRCP,it was showed diffuse and irregular narrowing of the main pancreatic duct and stricture of common bile duct located in pancreatic head in 4 cases.ERCP showed diffuse and irregular narrowing of the main pancreatic duct in 7 cases.Extra-pancreatic lesion included veins around pancreas involvement in 8 cases;multiple low density renal lesions in 6 cases; retroperitoneal fibrosis in 2 cases; stricture of hilar duct,interstitial lung disease and ankylosing spondylitis in 1 case,respectively.Conclusions AIP shows some characteristic imaging features,and imaging examinations play an important role in the diagnosis of AIP.Recognition of extra-pancreatic lesions aids in the correct diagnosis of AIP.

Objective To investigate the correlation between uric acid level and macrovascular disease in type 2 diabetic patients.Methods Sixty type 2 diabetic patients with lower limb atherosclerosis of carotid artery were randomly selected in study group who hospitalized in the First Hospital of Zibo from Mar.to Feb.2012.Sixty type 2 diabetes mellitus(T2DM) without carotid and lower limb athemsclerosis were served as control group.The blood pressure,blood lipid,blood glucose and other biochemical indexes,including blood uric acid,serum insulin (FNS),fasting blood glucose (FPG),apolipoprotein a (LP (a)),apolipoprotein A1,B (APO-A1,APO-B),glycosylated hemoglobin (HbA1c),high density lipoprotein cholesterol (HDL-C),low density lipopmtein cholesterol (LDL-C),triacylglycerol (TG) and total cholesterol (TC) were measured and determined.Results There was no significant difference in terms of blood pressure,blood lipid levels,APO-A1,APO-B,HbA1C,FNS and FPG in study group patiems (P ＞ 0.05).The level LP(a) in study group was (0.4 ± 0.2) g/L,significantly higher than that in control group ((0.2 ± 0.2) g/L; t =3.842,P ＜ 0.01).The blood uric acid level in study group was (362.3 ± 112.8)mmol/L,significantly higher than that of the control group((284.8 ±68.6)mmol/L;t =3.188,P＜0.01).Conclusion Uric acid and LP(a) are involved in the oocurrence and development of athemsclemsis,which is close related to the development of type 2 diabetic macmangiopathy.Therefore,in the process of preventing type 2 diabetes with macroangiopathy,we should pay attention to uric acid and LP (a) of the patient beside effective control of blood glucose,blood pressure,blood lipid level.

Objective: To analyze the mutations of BRCA1 in 9 Chinese familiar breast cancer patients. Methods: Peripheral blood samples were obtained from 9 patients enrolled from 9 breast cancer families, one normal control, 32 sporadic breast cancer patients and 33 normal donors. DNA extracted from lymphocytes was amplified by polymerase chain reaction (PCR). The 22 exons and partial introns of BRCA1 were screened by PCR denaturing high performance liquid chromatography (PCR-DHPLC) and confirmed by direct sequencing. Results: Among these 9 familiar breast cancer patients, a deleterious mutation was detected in one case in exon 11 (3870delTGTC) which was a 4 base deletion and caused a frameshift in turn. One novel and unique amino acid substitution (E867R) was detected in one case. Eight patients were detected to have a known variation in intron 18 (IVS18+65G→A), and the ratio of this variation detected was 88.9%(8/9). The ratio of this variation was 37.5%(12/32) in sporadic breast cancer patients or 33.3%(11/33) in normal control. This variation was found to be accompanied all the time with a known missense variation in exon 11 (P871L) and a polymorphism in intron 9 (IVS8 57delT). Those three variants were also detected in homozygous in one case, which implies the linkage of the 3 sites. The linkage had not been reported. Two patients had been found with a known polymorphism in exon 13 (S1436S). Another known polymorphism was found in one case (L771L). In addition, intronic variants (IVS2+48C→T, IVS2+133C→T, IVS12+112C→A) were detected. Conclusion: The mutations of BRCA1 in Chinese familiar breast cancer patients are different from the hot spots reported in Caucasian and Jewish. It is important that further study be conducted to seek for specific mutations of this gene or other possible relevant genes in Chinese familiar breast cancer patients.

Objective To study the effectiveness of niacinamide in treating maintenance hemodialysis patients with hyperphosphatemia.Methods It was a prospective and randomized controlled trial.Patients with hyperphosphatemia (serum phosphate ＞ 1.45 mmol/L) were randomly assigned into two groups:control group (continue their original phosphate binder and rocaltrol treatment) and niacinamide therapy group (additionally received niacinamide,titrated from 600 mg/d to 1200 mg/d).The treatment lasted for 8 weeks.Serum phosphate and calcium were tested every 2 weeks and normalized protein catabolic rate and other relevant indexes were tested monthly.Results 100 patients were recruited and 93 of them completed the trial,including 44 from the therapy group and 49 from the control group.By the repeated measures analysis of variance,changes of serum phosphate in two groups displayed a statistical significant difference,but the levels of serum calcium in both remained steady.At the end of trial,compared to control group,therapy group appeared decreased serum phosphate levels [(1.59±0.36) mmol/L vs (1.94±0.25) mmol/L,P ＜ 0.001] and increased serum HDL levels [(1.32±0.54) mmol/L vs (1.09±0.41) mmol/L,P=0.02].Meanwhile,two groups showed no significant difference in intact parathyoid hormone and alkaline phosphatase.Adverse reactions including thrombocytopenia and gastrointestinal dysfunction were observed in niacinamide therapy group.Conclusions Niacinamide is effective on controlling hyperphosphatemia along with phosphate binder in maintenance hemodialysis patients.It also increases the serum HDL levels.Nonetheless,it is important to monitor the number of platelet.

To enhance the immunogenicity of DNA and adenoviral vector vaccines expressing HIV-1 subtype B gp160, human interleukin 15 (hIL15) DNA adjuvant (pVR-hIL15) was constructed. BALB/c mice received DNA prime/protein boost immunization with pVR-HIVgp160/Ad5-HIVgp160 alone or combined with pVR-hIL15. Cellular and humoral immune responses were evaluated by IFN-gamma enzyme-linked immunosorbent spot assay and enzyme-linked immunosorbent assay, respectively. Compared with those immunized with vaccines alone, the mice immunized with vaccines combined with pVR-hIL15 had significantly increased specific cellular response and antibody titer (P < 0.05). It suggests that the IL15 DNA adjuvant can enhance the immune responses induced by prime-boost regimen using DNA and adenoviral vector encoding HIV-1 subtype B gp160.
