To study the anatomical features and classification of the angle between the right gastroepiploic vein (RGEV) and superior mesenteric vein/portal vein (SMV/PV) and to guide the catheterization of intraportal infusion chemotherapy through RGEV and reduce surgical complications.A retrospective three-dimensional (3D) computed tomography study was undertaken on 200 consecutive subjects with or without hepatic malignant tumors with a dedicated workstation 3D-MIA (the improved MI-3DVS workstation) developed by ourselves to determine the prevalence of surgically significant angle between RGEV and SMV/PV anatomic variations and its classification.The mean value of the angles between the end of RGEV and SMV/PV (AERS/P) (200 cases) was 84.2° ± 23.8 (31.4°-151.5°): 40.6° ± 92.3 (-177.9° to 178.0°) (sagittal angle), 81.7° ± 29.8 (-79.3° to 160.7°) (coronal angle), and 10.5° ± 94.3 (-178.7° to 175.8°) (horizontal angle). The mean value of the angles between the right bend of RGEV and SMV/PV (ARRS/P) (168 cases) was 104.8° ± 26.1 (20.5°-159.7°):49.3° ± 117.8 (-175.3° to 179.5°) (sagittal angle), 103.5° ± 37.7 (-178.8° to 168.9°) (coronal angle), and 12.6° ± 102.8 (-179.9° to 179.2°) (horizontal angle). The AERS/P were classified into large angle group (32 cases, 16%), middle angle group (113 cases, 56.5%), and small angle group (55 cases, 27.5%) based on angle variations and risks of catheterization.Precognition of the variations of AERS/P and ARRS/P before surgery is useful during chemotherapy pump catheterizing through RGEV in reduction of surgical complications by modulating the angle and direction of RGEV running into SMV/PV properly.

Numerous investigations on procalcitonin (PCT) have been carried out, although few with large sample size. To deal with the complexity of sepsis, an understanding of PCT in heterogeneous clinical conditions is required.Hospitalized patients aged 10-79 years were included in this retrospective and cross-sectional study. PCT tests were assayed within 2 days of blood culture.A total of 2952 cases (from 2538 patients) were enrolled in this study, including 440 cases in the 'positive BC' group, 123 cases in the 'positive body fluid culture' group, and 2389 cases in the 'negative all culture' group. Median PCT values were 4.53 ng/ml, 2.95 ng/ml, and 0.49 ng/ml, respectively. Median PCT values in the gram-negative BC group and gram-positive BC group, respectively, were 6.99 ng/ml and 2.96 ng/ml. Median PCT values in the 'positive hydrothorax culture' group, 'positive ascites culture' group, 'positive bile culture' group, and 'positive cerebrospinal fluid culture' group, respectively, were 1.39 ng/ml, 8.32 ng/ml, 5.98 ng/ml, and 0.46 ng/ml. In all, 357 cases were classified into the 'sepsis' group, 150 of them were classified into the 'severe sepsis' group. Median PCT values were 5.63 ng/ml and 11.06 ng/ml, respectively.PCT could be used in clinical algorithms to diagnose positive infections and sepsis. Different PCT levels could be related to different kinds of microbemia, different infection sites, and differing severity of sepsis.
