Convenience rice has become widely popular due to its easy availability for cooking. This study investigated the starch structure and composition of leachate and the microstructure of reheated convenience rice using novel processing technologies: super-heated steaming(SHS), auto-electric cooking(AEC), and pressurized-steam cooking(PSC). Additionally, the effect of two different target water contents(58% and 63%) was also evaluated. The PSC_63% sample had the highest total solids and amylopectin amount in the leachate. The amylopectin amount in the leachate differed significantly based on the targeted water content. Morphological characterization revealed that the swelling of starch and the coated layer on the surface of rice grains were most pronounced in the PSC_63% sample due to the pressure processing. The textural hardness of the AEC_58% sample was much higher than that of the other samples. The PSC_63% sample had the highest textural adhesiveness value, which can be attributed to the highest amylopectin amount in the leachate. Sensory characterization showed that the PSC_63% sample had the highest glossiness, whiteness, moistness, and overall acceptability. The principal component analysis score plots presented substantial differences in the leachate and textural and sensory characteristics of reheated convenience rice among the different processing technologies.

World Journal of Gastroenterology 2012年第34期18卷 4751-4757页

作者： jung Il Lee Jin-Woo Lee Joon Mee Kim Ja Kyung Kim hyun jung chung Young Soo Kim Department of Internal Medicine School of MedicineInha UniversityIncheon 400-711South Korea Department of Pathology School of MedicineInha UniversityIncheon 400-711South Korea Department of Internal Medicine Yonsei University College of MedicineGangnam Severance HospitalSeoul 135-720South Korea

AIM:To investigate whether expressing biliary phenotype predicted poor outcome after the surgical treatment in primary liver cancers. METHODS:Out of 204 patients that underwent liver resection due to hepatocellular carcinoma (HCC), liver specimens of 70 patients with HCC were evaluated for biliary components by cytokeratin (CK) 19 immunostain (CK19 - HCC and CK19 + HCC). CK19 positivity was defined as membranous and/or cytoplasmic expression in ≥ 5% of tumor cells with moderate or strong intensity. Patients with other primary liver cancers, such as com- bined HCC and cholangiocarcinoma (cHCC-CC), intrahe- patic cholangiocarcinoma (ICC) who received curative liver resection, were also included in the study. Clinical characteristics of CK19-HCC and CK19 + HCC patients, including survival outcome after curative liver resection, were compared with that of cHCC-CC and ICC patients. RESULTS: The overall survival (OS) rate of CK19 - HCC(n = 49) after the curative surgical treatment was 90.7%, and 80.4% at 1 and 5 years after the resection. OS rate of CK19 + HCC (n = 21) was 74.3%, 28.9% and OS rate of cHCC-CC (n = 22) was 66.7%, 32.2% at 1 and 5 years after the surgery. For ICC (n = 19), 1 and 5-year-OS rate was 50.2% and 14.3% after the cura-tive resection. The OS rates of CK19 + HCC and cHCC-CC were significantly lower than that of CK19-HCC, but higher than the OS rate of ICC (P = 0.000). There was no statistically significant difference in OS rate between CK19 + HCC and cHCC-CC. The disease free survival (DFS) rate of CK19-HCC was 72.0% and 54.5% at 1 and 3 years after the surgical treatment. DFS rate of CK19 + HCC was 53.3%, 34.3% and DFS rate of cHCC- CC was 51.5%, 39.2% at 1 and 3 years after the resection. For ICC, 1 and 3-year-DFS rate was 28.0% and 14.0% after the curative resection. DFS rate of CK19-HCC was significantly higher than that of ICC (P = 0.017), but marginally higher than DFS rate of either CK19 + HCC or cHCC-CC (P = 0.097, P = 0.089, respec-tively).

Giant choledocholithiasis treated by mechanical lithotripsy using a gastric bezoar basket

引用

World Journal of Gastroenterology 2012年第25期18卷 3327-3330页

作者： hyun jung chung Seok Jeong Don Haeng Lee jung Il Lee Jin-Woo Lee Byoung Wook Bang Kye Sook Kwon hyung Kil Kim Yong Woon Shin Young Soo Kim Division of Gastroenterology Department of Internal MedicineInha University School of MedicineIncheon 400-711South Korea

Mechanical lithotripsy （ML） is usually considered as a standard treatment option for large bile duct stones. However, it is impossible to retrieve oversized stones because the conventional lithotripsy basket may not be able to grasp the stone. However, there is no es- tablished endoscopic extraction method for such gi- ant stone removal. We describe a case of successful extraction of a 4-cm large stone using a gastric bezoar basket. A 78-year-old woman had suffered from upper abdominal pain for 20 d. Contrast-enhanced computed tomogram revealed a 4-cm single stone in the distal common bile duct （CBD）. Endoscopic stone retraction was decided upon and endoscopic papillary balloon dilation was performed using a large balloon. An at- tempt to capture the stone using a standard lithotripsy basket failed due to the large stone size. Subsequently, we used a gastric bezoar basket to successfully capturethe stone. The stone was fragmented into small pieces and extracted. The stone was completely removed after two sessions of endoscopic retrograde cholangio- pancreatography; each of which took 30 rain. No com- plications occurred during or after the procedure. The patient was fully recovered and discharged on day 11 of hospitalization. ML using a gastric bezoar basket is a safe and effective retrieval method in select cases, and is considered as an alternative nonoperative option for the management of difficult CBD stones.
