OBJECTIVE: To study the absorption and transport of pachymic acid (PA) isolated from the sclerotium of Poria cocos (Schw.) Wolf. in human intestinal epithelium. METHODS: By using Caco-2 (the human colonic adenocarcinoma cell lines) cell monolayers as an intestinal epithelial cell model, the permeability of PA was studied from apical side (AP side) to basolateral side (BL side) or from BL side to AP side. The PA was measured by reversed-phase high performance liquid chromatography coupled with UV detector at maximum absorption wavelength of 210 nm. Transport parameters and apparent permeability coefficients (Papp) were then calculated and compared with those of propranolol and atenolol, which were the transcellular transport markers for high and poor permeability respectively. RESULTS: The Papp values of PA were (9.50+/-2.20) 10(-7) cm/s from AP side to BL side, and (11.30+/-5.90) 10(-7) cm/s from BL side to AP side, respectively. Under the condition of this experiment, the Papp values were 1.45x10(-5) cm/s for propranolol and 4.22x10(-7)cm/s for atenolol. CONCLUSION: PA is transported through the Caco-2 cell monolayer in a concentration-dependent manner and the transport was linear with time. The absorption in apical to basolateral direction and secretion in basolateral to apical direction were poor and their Papp values were comparable to atenolol. Besides passive diffusion of PA, ATP is partially involved in its transport.

Objective To investigate the association of the SNP in miRNA146A with genetic prediposion and earlier recurrence after resection for hepatocellular carcinoma (HCC).Methods In the casecontrol study including 173 HCC cases,DNA were exacted from cancer tissue embedded with paraffin and were amplificated by PCR,SNP was explored in gene sequence of miRNA146a (385 base pair including extron).The outcome were analyzed with genetic prediposion and clinical features.Result Only hsa-mir-146a rs2910164 was found.The genetype frequence of C/C 、G/G and C/G at rs2910164 gene locus were separately 61 (35.3％),21 (15％) and 86(49.7％) in cases.Compared to G/G genetype,C/C and C/G genetype were danger factor to onset risk of HCC (OR =3.086,95％ CI:1.289-7.390) ; C/G was danger factor to earlier recurrence after resection(OR =8.179,95％ CI:2.248-29.759).Conclusion rs2910164 may be associated with genetic prediposion and earlier recurrence after resection of HCC in Jiangxi hans

ObjectiveTo investigate the clinical effect of three-dimensional conformal radiotherapy simultaneously combined with XELOX program(oxaliplatin +capecitabine) for local recurrence of esophageal carcinoma after radiotherapy.MethodsSixty patients with local recurrence of esophageal carcinoma after radiotherapy were divided by random digits table method into treatment group and control group with 30 cases each.The patients in treatment group were treated with three-dimensional conformal radiotherapy simultaneously combined with XELOX program chemotherapy.While control group received three-dimensional conformal radiotherapy.The efficacy between two groups were compared.ResultsThe complete remission rate and efficiency rate in treatment group were significantly higher than those in control group [ 53.3％ (16/30) vs.23.3％ ( 7/30 ),86.7％ ( 26/30 ) vs.63.3％ (19/30) ] ( P ＜ 0.05 ).The 1,2,3-year survival rate and median survival time in treatment group were 65.5％,44.8％,34.5％ and 24.8 months,which were significantly higher than those in control group (48.3％,41.4％,6.9％ and 12.1 months)(P ＜0.01 ).The incidences of radioactive esophagitis,radioactive pneumonia and thrombocytopenia in treatment group were higher than those in control group,but there were no statistical differences between two groups (P ＞0.05).The incidences of nausea,vomiting,leukocyte decrease and anemia in treatment group were significantly higher than those in control group [36.7％(11/30) vs.13.3％(4/30),40.0％(12/30) vs.16.7％(5/30),43.3％( 13/30 ) vs.13.3％(4/30),P ＜ 0.05 ].ConclusionsThree-dimensional conformal radiotherapy simultaneously combined with XELOX program can improve short-term efficacy and long-term survival rate of local recurrence of esophageal carcinoma after radiotherapy.

Histone acetylation and deacetylation is an important regulatory way of gene expression in eukaryotic cells. As a key regulatory enzyme, histone deacetylase is overexpressed in many malignant tumors, including hepa- tocellular carcinoma. In addition, it has been suggested to be a potential therapeutic target for solid tumors. In this study, we review the classification, mechanisms, as well as the expression and regulation of histone deactylases in hepatocelhlar carcinoma.

Expansive type of hepatocellular carcinoma (HCC) is a subtype of HCC. Correlation between the preoperative sonography and postoperative pathology was studied in 35 cases of HCC. According to the classification of nakashima, 21 cases belonged to the expansive type whereas the other 14 cases the infiltrative type. Different from the infiltrative type. the expansive type of HCC had four specific sonographic appearances: hypoechoic ring, hypoechcic halo, pedunculated and small nodular echo which had different pathological bases. Expansive tyje of HCC was not so commonly seen as infiltative type but its rate of surgical resection was mu~h higher than that of infiltratine type (JP< 0. 01). Thus, it is the kind of HCC with significant clinical importance. Preoperative ultrasonographic diagnosis help to decide the way of treatment.

Whole rice grain was dissected by hand into fractions of pericarp, ale-urone, scutellum, embryo and endosperm. For the convenience of having enough amount of samples for amino acids assay some of which were recom-bined and finally three parts, pericarp +aleurone layer, scutellum + embryo and endosperm, were obtained. Protein, lysine, methionine, threonine and valine contents were determined for each part. The data obtained indicated that although total weight of the first two parts accounted for only 7.27-8.43% of the whole grain, they contributed 14.5-15.8% protein, 29.0-30.5% lysine, 11.8% melhionine, 16.8% valine and 19.4% threonine, contained in the whole grain. During husking process it indicated that the lesser amounts of pericarp, aleurone, scutellum and embryo were retained and the larger percentage of protein and lysine was lost. This fact was identified either by a specially designed miller in the laboratory or a commonly used sand wheel miller in the factory. The suitable degree of milling for rice was discussed and it was proposed that 92% extration for rice rather rational.
