Methods:  We consecutively enrolled 58 distal radical subtotal gastrectomy (RSG) patients (male/female: 44/14, age: ICG-001 manufacturer 33–79 years) to receive an electrogastrographic (EGG) measurement. Their Helicobacter pylori status and dyspeptic score were simultaneously assessed. In addition, EGG data of 58 age- and sex-matched healthy subjects were compared. Based on power spectral analysis,

the following EGG parameters were derived: dominant frequency (DF)/power (DP), percentage of normal rhythm (2–4 cpm), power ratio (PR) referring the postprandial power change, etc. Results:  Visual analysis occasionally found a short period of ∼11 cpm myoelectricity-like rhythm. Distal RSG patients had lower fasting

(1.90 ± 0.69 vs 2.97 ± 0.58 cpm, P < 0.001) and postprandial (2.03 ± 0.72 vs 3.35 ± 0.27 cpm, P < 0.001) DF values, while their fasting (36.2 ± 22.3% vs 67.1 ± 23.4%, P < 0.001) and postprandial (33.4 ± 19.9% vs 82.2 ± 16.7%, P < 0.001) percentages of normal rhythms were diminished. In contrast, fasting DP, its meal response and PR (2.99 ± 2.40 vs 2.45 ± 2.63, NS) were comparable to those of controls. Neither gender, age, type of gastroenterostomy, Helicobacter pylori colonization, dyspeptic score nor elapsed time after surgery had an obvious influence on EGG parameters. Conclusions:  Distal RSG patients may have decreased SW frequency and less meal ingestion changed EGG parameters in terms of SW frequency, MCE normality and stability, whereas their EGG power remained unchanged irrespective of meal ingestion. “
“Although Selleck AT9283 chronic infection with hepatitis B virus (HBV) and/or hepatitis C virus (HCV) are the most important risk factors for the development of hepatocellular carcinoma (HCC) worldwide, the proportion of HCC patients negative for the hepatitis B surface antigen and hepatitis C antibody, so-called “non-B non-C HCC”,

is rapidly increasing, especially in Japan. The background liver diseases of non-B non-C HCC patients can be multifactorial, including occult HBV infection and non-alcoholic steatohepatitis. It is reasonable to investigate the non-cancerous liver tissues to identify the potential molecular mechanisms responsible for the processes of hepatocarcinogenesis of non-B non-C HCC. However, to date, only a few studies have focused on this research concept based on the idea of “field cancerization”. This review highlights the potential importance of the molecular analysis of non-cancerous liver tissues to clarify the molecular characteristics in patients with non-B non-C HCC. A better understanding of the molecular mechanisms underlying the individual predisposition to non-B non-C HCC will lead to improvements in the prevention, early diagnosis and treatment of this neoplastic disease.
