OBJECTIVETo evaluate the academic level and the popularity of the Chinese Journal of Hepatology in China in 2005.

METHODSWe used bibliometrics to analyze statistically the original articles of the Chinese Journal of Hepatology cited by Chinese periodicals included in the Wanfang Data in 2005.

RESULTS(1) 699 published papers in the journal in 2005 were cited 1673 times and 44 of them were cited 720 times in total. (2) The papers published in the Chinese Journal of Hepatology were cited by journals in China starting from 1993 through 2005. Of all the cited articles, 1.49% of them were cited in the same year as they were published. (3) Non-specific rate of the Chinese Journal of Hepatology was 96.17%, and self-cite rate was 3.83%. (4) Papers published in the Chinese Journal of Hepatology were cited by 400 Chinese periodicals, 99 of them are journals included in the Chinese Science Citation Database, and 110 of them are Chinese core periodicals.

OBJECTIVETo investigate the difference of the prevalence of t(11;18)(q21;q21)/API2-MALT1 fusion gene between gastrointestinal mucosa-associated lymphoid tissue (MALT) lymphoma and diffuse large B cell lymphoma (DLBCL).

METHODSA total of 57 cases gastrointestinal MALT lymphomas (38 gastric and 19 intestinal lymphomas), 32 DLBCL (28 gastric and 4 intestinal lymphomas) and 7 cases gastric DLBCL accompanied MALT lymphoma were collected from the Cancer Hospital of Fudan University. API2-MALT1 fusion gene was detected by fluorescent in situ hybridization (FISH) using both dual fusion translocation and break apart probes.

RESULTSAmong gastrointestinal MALT lymphomas, API2-MALT1 fusion gene was found in 12 of 57 cases (21.1%, 10 gastric and 2 intestinal lymphomas). In contrast, the fusion gene was not found in all 32 DLBCL and 7 gastric DLBCL with MALT lymphoma component. There was statistical significant difference between two groups (chi(2) = 9.383, P = 0.001).

CONCLUSIONSAPI2-MALT1 fusion gene is a distinctive genetic aberration in MALT lymphomas, and is not present in DLBCL. The findings suggest that gastrointestinal tract MALT lymphomas with API2-MALT1 fusion gene may not transform into DLBCL, which may represent primary lymphoma or transformed API2-MALT1 negative MALT lymphomas.

OBJECTIVETo evaluate an enzymatic method for determining serum beta-hydroxybutyrate (beta-HB) with the National Committee for Clinical Laboratory Standards (NCCLS) projects, and to discuss its clinical values in diabetic ketoacidosis (DKA).

METHODSThe precision, accuracy, specificity, linearity and interference of the enzymatic method were analyzed. This method was used to determine serum beta-HB in 60 cases of normals, 50 cases of diabetes, and 34 cases of DKA by autochemistry analyzer.

RESULTSEnzymatic beta-HB assay was precise (within-run CV, day-to-day CV, and total CV < 5%). The linearity studies showed the method was linear up to 4 mmol/L. Recovery rate was 98.5%-104.1%. Hemolysis (Hemoglobin up to 18.2 g/L), icteric samples with total bilirubin up to 224 mumol/L, and lipemia up to triglyceride concentration of 2.28 mmol/L did not interfere with the beta-HB results in this method. Serum beta-HB levels were significantly elevated in DKA patients compared with DM patients and controls (P < 0.01). Positive rate of serum beta-HB in DKA patients was significantly higher than that of urinary ketone (P < 0.05).

CONCLUSIONSEnzymatic method is convenient and reliable, allows full automation, and is rapid enough to be used for both routine and urgent determinations of serum beta-HB. It can be used in diagnosing and monitoring treatment of DKA.

OBJECTIVETo evaluate various kinds of sequences and modified dynamic contrast-enhanced MRI methods in the diagnosis of pancreatic carcinoma.

METHODSForty-nine pancreatic carcinoma patients proved by histopathology or clinical examination and follow-up underwent MR examination. Plain MR sequences included: T1-weighted 2D FLASH, T1 WI 3D VIBE, TSE T2 WI and HASTE with FS. Modified dynamic contrast-enhanced scanning procedures were coronal scaning with 3D FLASH and axial scaning using T1 WI 3D VIBE sequences in turn for the upper abdominal area and pancreatic area. The coronal imaging were used to obtain 3D peripancreatic vessels during arterial phase and portal vein phase scanning, respectively. The axial imaging were used to detect the tumor in pancreatic parenchymal phase and delayed phase scanning, respectively. Final scanning for the whole upper abdomen was performed using T1 WI 2D FLASH axial sequence.

RESULTS(1) Of 49 lesions in these patients, 45 showed hypo-intensity and 4 iso-intensity on 3D VIBE. Forty-six lesions showed hypo-intensity and 3 isointensity on 2D FLASH. On TSE T2 + FS, lesion contour was not clear enough; 3 of them displayed isointensity, the other showed iso- or hyper-intensity. (2) During pancreatic parenchymal phase, 48 lesions showed hypo-intensity and 39 ring enhancement. Twenty-four lesions displayed marginal tubercle and inner compartment enhancement during portal vein and delayed phase. Six lesions showed iso- or hyper-intensity in delayed phase. (3) Thirty-seven patients underwent surgical exploration. MRI and MRA had a good correlation with surgical findings for peripancreatic vessels which were diagnosed as being invasive or noninvasive by tumors except three superior mesenteric arteries and four superior mesenteric veins being misdiagnosed.

CONCLUSIONAs"one-stop-shop" MRI examination, modified MRI sequences consisting of dynamic coronal and axial contrast-enhanced scanning is feasible and helpful in diagnosing, staging and assessing the resectability for pancreatic carcinoma.
