Objective To evaluate the diagnostic and differential value of triphasic, especially the arterial phase, contrast enhanced CT scans for the hepatocellular adenoma, and to improve CT diagnostic accuracy. Methods Spiral CT scanning of pre and post contrast arterial phase, portal venous phase and delayed phase was performed in 5 patients with hepatocellular adenomas proved surgically and pathologically. The enhancement was administrated with venous injection of 3 ml/sec, totally 100 ml angiografin. Arterial phase of contrast enhanced scanning started 20～30 sec, portal venous phase 60～70 sec and delay scanning 3 min after the injection of contrast medium. The degrees of the enhancement of adnoma and normal tissues of liver in the three contrast enhanced phases were calculated and compared statistically. Results In plain CT, the lesions were iso density in 4 cases and slight hypodensity in 1 case, which was hardly distinguished from the normal tissue. In all 5 cases, the lesions showed marked enhancement in the arterial phase compared with normal tissue of liver (38 HU high), and there were markedly statistical difference ( t =18 94, P 0.05). The mean CT value of hepatocellular adenoma in the arterial phase was much higher than that in portal venous and delay phase, there were statistical differences between them ( F =18.39, P

Objective To study MR imaging manifestations of the mesorectum and mesorectal fascia. Methods 100 cases were divided into five groups according to the age. All MR images were retrospectively observed and analyzed by two radiologists.The observing contents included: ①exhibition of the mesorectal fascia, ②the signal intensity of the mesorectum and the pelvic fat and ③the thickness ratio of the mesorectum and the subcutaneous fat in different ages. All data were dealed with SPSS 10.0 software. Results The showing rate of the anterior, posterior, left and right mesorectal fascia respectively were 77, 100, 91 and 93 by MR imaging. The signal intensity of the mesorectum(550.8843) was significantly higher than that(469.8693) of pelvic fat in all five groups(P﹤0.05) and the signal difference between the mesorectum and the pelvic fat could be detected by naked eye. The thickness of the mesorectum and the subcutaneous fat had no association with ages.Conclusion MRI can display the mesorectum and mesorectal fascia clearly. The signal intensity of the mesorectum is significantly higher than that of pelvic fat in five groups. The thickness of the mesorectum and the subcutaneous fat have no association with ages.

AIM:Activin A,a member of transforming growth factor superfamily,is the negative regulator factor in liver regeneration. In this study,the effects of extract of Ginkgo Biloba on hepatic fibrosis and the expression of Activin A in rats with cirrhosis were investigated. METHODS:The experiment was performed at in the Central Laboratory of Wuhan First Hospital from September 2005 to December 2006. ①Thirty-six male SD rats of(160?20) g were randomized into 3 groups:control group,model group and treatment group. ② Except the rats in the control group,others were intraperitoneally injected with 500 mL/L CCl4 for 8 weeks to establish models of hepatic fibrosis. Meanwhile,the extract treatment group was infused with the extract of Ginkgo Biloba(Chinese drugs preparation laboratory of Wuhan First Hospital,detected by Hubeu Wushi Medicine Industry Co.,Ltd. No. 02-391) daily for 8 weeks. ③After administration,all anesthetized rats were sacrificed. Blood samples were collected for the determination of liver function biochemical indexes. Liver tissue samples were used for histopathological examinations. The expression of Activin A was determined by immunohistochemistry and RT-PCR. RESULTS:All 36 rats were involved in the final analysis. ①The liver function in extract treatment group was significantly improved compared with that in model group. ②The grade of fibrosis in extract treatment group were remarkably lower than that in model group under light microscope. ③The positive staining of Activin A in treatment group was significantly reduced compared with model group. ④The expression of Activin A mRNA in extract treatment group was significantly reduced compared with model group. CONCLUSION:Extract of Ginkgo Biloba can effectively decrease the expression of Activin A in rats with hepatic fibrosis caused by CCl4,and lessen the degree of hepatic fibrosis.

Objective To study the protective effect of hydrogen sulfide(H2S) on intestinal ischemia-reperfusion(I/R) injury so as to provide a new clinical treatment on I/R.Methods NaHS was taken as a donor of H2S.Forty Sprague-Dawley rats were divided into 5 groups with 8 rats in each group: sham operation group,I/R model group,tetram ethylpyrazine group,and NaHS 7 ?mol/kg and 14 ?mol/kg groups.The contents of superoxidase dismutase(SOD),malondialdehyde(MDA) and glutathione peroxidase(GSH-Px) in serum and intestinal tissue were measured,respectively.The intestinal mucosal injury and histological alteration were observed.Results The content of MDA within serum and intestinal tissue was significantly reduced and the activities of SOD and GSH-Px were significantly increased.H2S could obviously reduce the injury in intestinal mucosa and glands.Conclusion H2S possesses a protective effect on intestinal I/R injury in rats.

OBJECTIVE:To provide a reference for reducing adverse events due to off-label use of drugs and promoting ratio-nal use of intravenous drugs in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine. METHODS:The pre-scriptions of intravenous drugs in 42 wards of our hospital from Jul. 2013 to Jun. 2014 were reviewed,and then off-label use of drugs were analyzed,where statistics was made mainly to drug overdose,the use of drugs at the concentration beyond the standards (including concentrations too high and too low) and associated conditions. RESULTS:There were 622 irrational prescriptions,in-cluding 60 concerning off-label use of drugs,accounting for 9.6% of irrational prescriptions,in which 40 were involved with the concentration which was too high,accounting for the highest percentage(66.7% of prescriptions related to off-label use of drugs), 17 were related to drug overdose(28.3% thereof),and 3 were in relation to the concentration which was too low(5.0% thereof). CONCLUSIONS:Pharmacy intravenous admixture service may,through the communication between the pharmacist and the doc-tor,refuse to make up the above-mentioned prescription which was found to be irrational(including that involving in off-label use of drugs)or make up such prescription after it is modified according to the requirements as specified in the label to reduce the occur-rence of off-label use of drugs so as to promote rational drug use.

Small intestinal neuroendocrine carcinoma is poorly differentiated,highly malignant,and originated from the diffuse neuroendocrine system.It diffusely expresses the general neuroendocrine differentiation markers.The disease can be manifested as carcinoid syndrome,but most of the patients were with occult onset and absence of specific clinical symptoms,which led to difficult diagnosis before operation.On June 18,2012,a patient with manifestation of recurrent vague abdominal pain received capsule endoscopy at the Northern Jiangsu People's Hospital.The capsule endoscope was retained in the distal small intestine,and malignant ileum lesion was revealed during the surgical exploration.Finally,poorly differentiated neuroendocrine carcinoma with abdominal wall metastases was identified by pathological examination.
