Hepatocellular carcinoma （HCC） is a so highly invasive tumor that metastasizes hematogenously and lymphogenously to distant site. Frequent sites are lung, regional lymph node, bone, and adrenal gland. But metastasis to the gastrointestinal （GI） tract is rare, and most common site is stomach. Metastasis to the small intestine is extremely rare. Moreover, metastatic HCC of the small bowel causing intussusception has not been reported until now. Here, we report a case of metastasis of HCC to the small bowel manifested by intussusception.

AIM:To investigate the outcome and effectiveness of two screening programs,National Cancer Screening Program(NCSP)and opportunistic screening(OS),for the detection of gastric cancer. METHODS:A total of 45 654 subjects underwent upper endoscopy as part of the NCSP or OS at the Chung-Ang University Healthcare System in Korea between January 2007 and December *** study population was comprised of subjects over the age of 40 *** specifically,subjects who took part in the NCSP were Medicaid recipients and beneficiaries of the National Health Insurance *** photo-graphs from the endoscopies diagnosed as gastric cancer were reviewed by two experienced endoscopists. RESULTS:The mean age of the screened subjects was 55 years for men and 54 years for women.A total of 126 cases(0.28%)of gastric cancer were detected from both screening programs;100 cases(0.3%)from NCSP and in 26 cases(0.2%)from *** proportion of early gastric cancer(EGC)detected in NCSP was higher than that in OS(74.0%vs 53.8%,P=0.046). Among the 34 416 screenees in NCSP,6585(19.1%) underwent upper endoscopy every other year as *** the 11 238 screenees in OS,3050(27.1%) underwent upper endoscopy at least once every two years during the study *** detection rate of gastric cancer was found to be significantly higher during irregular follow-up than during regular follow-up in both screening programs(0.3%vs 0.2%,P=0.036).A higher incidence of EGC than advanced gastric cancer was observed during regular follow-up compared with irregular follow-up. CONCLUSION:Compliance to the screening program is more important than the type of screening system used.

Going beyond an improved colour gamut,an asymmetric colour contrast,which depends on the viewing direction,and its ability to readily deliver information could create opportunities for a wide range of applications,such as nextgeneration optical switches,colour displays,and security features in anti-counterfeiting ***,we propose a simple Fabry–Perot etalon architecture capable of generating viewing-direction-sensitive colour contrasts and encrypting pre-inscribed information upon immersion in particular solvents(optical camouflage).Based on the experimental verification of the theoretical modelling,we have discovered a completely new and exotic optical phenomenon involving a tuneable colour switch for viewing-direction-dependent information delivery,which we define as asymmetric optical camouflage.

Hepatocellular carcinoma （HCC） is one of the most frequent complications in patients with .liver cirrhosis. HCC without cirrhosis is rareand obviously a different entity. Treatment depends on tumor stage, liver function and general performance. Results of locoregional treatment, resection or liver transplantation are superior to those of medical therapy. Surgical approaches are potentially curative. Underlying cirrhosis is usually the limiting factor for the extent of resection and persists after resection. Liver transplantation eliminates both cirrhosis and, potentially, the tumor. Whereas surgery （functional liver capacity provided） may be performed even in advanced tumors, liver transplantation is advocated in less advanced （T2） tumors in order to keep the rate of recurrent tumor low. Responsible use of scarce grafts requires sticking to this rule.

To the Editor: Xanthogranulomatous cholecystitis(XGC) is an uncommon inflammatory disease of the gallbladder, and its incidence is reported to be 1.3%-5.2% [1]. XGC is diagnosed by histopathological examination, characterized by severe inflammatory destruction followed by a granulomatous reaction, marked proliferative fibrosis, and infiltration of inflammatory cells [2].

AIM： To observe the effects of traditional antiinflammatory medicine Lonicerae FIos （LF） on rat reflux esophagitis （RE） induced by pylorus and forestomach ligation compared with the well-known proton antioxidant, α-tocopherol. METHODS： Rats were pretreated with three different dosages of LF （500, 250 and 125 mg/kg） orally, once a day for 14 d before pylorus and forestomach ligation. Nine hours after pylorus and forestomach ligation, changes to the stomach and esophagus lesion areas, gastric volumes, acid and pepsin outputs, antioxidant effects, esophageal lipid peroxidation, superoxide dismutase （SOD）, catalase （CAT）, malondialdehyde （MDA）, myeloperoxidase and glutathione （GSH） levels, and collagen contents （marker of flexibility） were observed on the esophageal and fundic histopathology. The results were compared with an α-tocopherol （once orally, 1 h before operation, 30 mg/kg） treated group in which the effects on RE were already ***： Pylorus and forestomach ligations caused marked increases of gross esophageal and gastric mucosa lesion areas, which corresponded with histopathological changes. In addition, increases of esophageal lipid peroxidation, decreases of SOD, CAT, and GSH-free radical scavengers, increases of collagen were observed. However, these pylorus and forestomach ligation induced RE were dose-dependently inhibited by treatment of 500, 250 and 125 mg/kg of LF extract, mediated by antioxidant effects. RE at 250 mg/kg showed similar effects α-tocopherol. CONCLUSION： The results suggest that antioxidant effects of LF could attenuate the severity of RE and prevent the esophageal mucosal damage, and validate its therapeutic use in esophageal reflux disease.

Dear Editor,Optic perineuritis is a rare inflammatory disorder involving the optic nerve sheath and its adjacent *** condition shows dramatic responses to steroid treatment, although relapse is common. Additional characteristics of optic perineuritis include the sparing of central vision on a visual field test, relatively good initial visual acuity, and optic disc edemaI^l. Most cases are idiopathic, although some rare cases have been associated with specific infections, such as syphilis and viral infections, and autoimmune disorders including We- gener＇s granulomatosis, sarcoidosis, and giant cell arteritis.
