ABSTRACT

Objective To explore the expression of transcriptional regulation factor FHL 1 in pancreatic fibrosis of chronic pancreatitis (CP) and clinical significance.Methods Serum samples from 20 CP patients treated in the Department of Gastroenterology , Nanjing General Hospital and 20 healthy controls in the corresponding period were collected .The level of FHL1 in the serum was detected by ELISA .Twenty male Wistar rats were randomly divided into control group and CP group according to the body weight .The CP rat model was established by injecting dibutyltin dichloride ( DBTC) through tail vein .All the rats were killed at 28 days after injection and the pancreas was collected , which was observed using hematoxylin and eosin ( HE) staining to investigate pathological changes . The expression of FHL1 in pancreas was measured by immunohistochemistry (IHC) and Western blotting (WB).Results The average of serum FHL1 level in two groups were (0.86 ±0.22)g/L and (1.18 ±0.22)g/L, respectively.The level of FHL1 in serum of CP patients was significantly lower than that of healthy cases , and the difference was statistically significant (t=10.54, P=0.001).Damaged pancreatic lobular structure , acinar atrophy and the obvious fibrous hyperplasia were observed in CP rats .The pathological score of abnormal structure , acinar atrophy, fibrosis, and inflammatory cell infiltration in the pancreas of the CP group was (2.2 ±0.4),(2.0 ±0.7),(2.4 ±0.3) and (2.8 ±0.6), respectively, but was all 0 in control group.The difference between two group was statistically significant ( t value =17.24, 9.01, 25.22 and 14.75, respectively, all P<0.001).The expression of FHL1 in the pancreatic tissue of CP group were less than that of normal group , and the difference was statistically significant (IHC:15 798 ±3 247 vs 37 570 ±9 254, t=2.438,P=0.016;WB:0.44 ±0.11 vs 0.89 ±0.03, t=4.289, P=0.002).Conclusions The protein of FHL1 was in low expression in the pancreas of CPs , indicating that FHL1 may participate in the formation of pancreatic fibrosis .

ABSTRACT

Arteriovenous malformations (AVMs) comprising a feeding artery, nidus, and draining vein rarely develop in the gastrointestinal tract. Although almost all AVMs are asymptomatic, they cause massive painless rectal bleeding and subsequent chronic anemia. The definitive diagnosis of AVM is achieved by selective mesenteric angiography, and surgical resection is the treatment of choice. We detected an intestinal AVM involving the descending colon in a patient with severe hematochezia. The diagnosis was made by CT angiography performed using a 64-channel MDCT and the obtained 3D reconstruction images. The AVM showed an extensive vascular network on CT images, and it was treated by surgical resection. Here, we report this case of an intestinal AVM along with its imaging findings.
