[Differentiation between hyperintense hepatocellular carcinoma and focal nodular hyperplasia in hepatobiliary phase with multimodal parameters of magnetic resonance imaging].

Objective: To differentiate hyperintense hepatocellular carcinoma (HCC) with focal nodular hyperplasia (FNH) in the hepatobiliary phase by MRI multimodal parameters. Methods: A retrospective cross-sectional study method was adopted. Clinical data on 15 cases with hyperintense HCC and 15 cases with FNH in the hepatobiliary phase admitted to the First Affiliated Hospital of the Army Medical University from January 2012 to December 2019 were collected. All patients with solitary lesions who underwent Gd-EOB-DTPA-enhanced MRI examinations were included. Surgically resected specimens were verified by pathological and immunohistochemical examination. HCC and FNH imaging features were analyzed by two radiologists. Results: (1) HCC and FNH apparent diffusion coefficient (ADC) values were 1 205.07±239.65×10-3 mm2/s and 1 434.73±217.6×10-3 mm2/s, respectively, and the SIADC difference was statistically significant (P<0.05) between the two groups. (2) In the dynamic contrast-enhanced MRI sequence, 15 cases of HCC were significantly enhanced in the arterial phase, of which 13 cases were characterized by continuous enhancement, and 2 cases were characterized by wash-in and wash-out enhancement. There was no statistically significant difference (P>0.05) between the two groups. SIenhancement rate between HCC and FNH (1.39±0.60 vs. 1.33±0.50, P>0.05) had no significant difference. (3) HCC and FNH morphological features in the hepatobiliary phase included: annular hypointensity: HCC (8 cases) vs. FNH (0 cases); contrast filling defects: HCC (8 cases) vs. FNH (0 cases); linear hyposignal separation: HCC (10 cases) vs. FNH (0 cases); and stellate scars: HCC (0) vs. FNH (5 cases), and there were statistically significant differences (P<0.05) between the two groups . Conclusion: Multimodal MRI have significant value for differentiating hyperintense HCC and FNH in the hepatobiliary phase.

Correction of corrected transposition of the great arteries associated with cardiac anomalies.

Reported in this paper are 8 cases of corrected transposition of the great arteries associated with anomalies. All the patients underwent the repair of the ventricular septal defect and atrial septal defect, the replacement of left-side tricuspid value, the pulmonary valvotomy and the placement of extra-cardiac conduit to the pulmonary trunk respectively with no hospital death after operation. The paper also described the selection of the heart incision, the prevention of injury of the conduction system and indication of the placement of extra-cardiac conduit.

[Effects of nine prescriptions on fever in rats induced by endotoxin].

In this paper in is reported that nine prescriptions often used in traditional Chinese medicine for the treatment of diseases with fever were tested experimentally for the effect on fever of rats induced by endotoxin. The results are as follows: Da-yuan-decoction, Gan-lu-xiao-du-pill, Lian-pu-decoction, Cai-hao-mixture, Da-huang-huang-lian-jie-du-decoction, Tao-ren-cheng-qi-decorction, Ge-gen-qin-lian-decoction, Yin-qiao-jie-du-decoction etc. can notably reduce fever in rats induced by endotoxin with the exception of Bai-hu-decoction that has no obvious effect on fever-reduction.
