Bronchoarterial and left gastric arterial drug infusion therapy were carried out in 27 cases of inoperable,advanced esophageal cancer;with DMVC method on squa- mous carcinoma and FAM method on adenocarcinoma.Near future good results were ob- tained by raising the survival rate and life quality.The authors put emphysis on the discus- sion of the indications and theoratic points of interventional therapy.

OBJECTIVETo explore the relationships between quality of life, negative life events, social support and suicide ideation among undergraduates in colleges.

METHODS3517 undergraduates in colleges were recruited by multistage stratified random clustered sampling method. Factors associated with suicide ideation were analyzed with logistic regression by scores of Beck Scale for Suicide Ideation(BSSI), Generic Quality of Life Inventory (GQOLI), Adolescent Self-rate Life Events Checklist (ASLEC), Social Support Rating Scale (SSRS) and a questionnaire on background information.

RESULTSThe rate of suicide ideation within 7 days was 14.1%, especially in females (15.96%), with single parent (23.79%) and disabled undergraduates (25.00%). The primary risk factors for suicide ideation were with low psychological function, material life, family/social support, lower availability of support and more negative life events.

CONCLUSIONThe prevalence of suicide ideation among these undergraduates was high, appropriate measures focusing on these risk factors should be implemented.

OBJECTIVETo establish a new culture method to induce the differentiation of embryonic pancreatic cells into mature endocrine cells.

METHODSMouse embryos at day 12.5 were used and embryonic pancreata were isolated. The isolated embryonic pancreata were cultured on the filter for 7 days, which floated in the dish containing medium. During culture, the expression of pancreas duodenum homeobox-1 (PDX-1), a pancreatic stem cell marker, was examined at day 1. The expression of neurogenin 3 (Ngn3), a pancreatic progenitor cell marker, was examined at day 3. The expressions of endocrine and exocrine markers, insulin, glucagon, and carboxypeptidase (CPA) were examined at day 7 by immunohistochemistry. The kinetics of pancreatic marker expression during culture was assayed by real-time PCR.

RESULTSMany pancreatic stem cells still existed in embryonic pancreata cultured for 1 day; meanwhile, these pancreatic stem cells proliferated in high rate. A large amount of pancreatic progenitor cells were found in embryonic pancreata cultured for 3 days.Pancreatic stem/progenitor cells differentiated into mature endocrine and exocrine cells in embryonic pancreata after having been cultured for 7 days. Furthermore, the expression pattern of pancreatic marker is consistent with that in vivo.

CONCLUSIONWe successfully established a new culture method, with which embryonic pancreatic cells can efficiently differentiate into mature endocrine cell.

In order to study the relationship between lengths of homologous fragments and chromsomic recombination rate in Saccharopolyspora erythraea, three homologous sequences, with mutant loci and different flanking sequences, (26bp + 27bp), (500bp + 576bp) and (1908bp + 1749bp), were synthesized by chemical reaction or PCR amplification, and cloned into pWHM3 to construct homologous recombination plasmids, pWHM1113, pWHM1116 and pWHM1119. When the plasmids were transformed into protoplast of Saccharopolyspora erythraea A226 under PEG mediated, on an average 30, 69 and 170 transformants grew on each plate for the three plasmids respectively, but chromosomic integration frequency were 0, 2% and 19% among corresponding transformants. Both pWHM1116 and pWHM1119 could take double crossover recombination, and exchange the mutant loci in the chromosome. It was concluded that when the flanking sequences were equal or more than (500bp + 576bp), they could take effective single and double recombination with Saccharopolyspora erythraea chromosome.

OBJECTIVETo investigate the association of the ATP-binding cassette sub-family G member 1 (ABCG1) gene polymorphisms with coronary atherosclerotic disease (CAD) in Chinese Han population.

METHODSA population based case-control association study was carried out in 541 patients with CAD and 649 healthy controls from Chinese Han population. Two single nucleotide polymorphisms (SNPs) of the ABCG1 gene were genotyped using polymerase chain reaction-restriction fragment length polymorphism. Logistic regression was used to compare the genotypic and allelic frequency difference.

RESULTSThe frequency of allele C of rs225374 was significantly higher in the CAD patients than that in the healthy controls (OR=1.186, 95%CI: 1.009-1.394, P=0.039), while the difference was also significant in the male subgroup (OR=1.236, 95%CI: 1.014-1.506, P=0.036). A statistically higher frequency of rs1044317 allele A was found in the CAD patients in comparison to the healthy controls (OR=1.187, 95%CI: 1.009-1.397, P=0.039). In case-only association study, rs225374 showed significant association in the high Gensini score group compared with the low Gensini score group (OR=1.303, 95%CI: 1.024-1.657, P=0.031).

CONCLUSIONThe two SNPs of the ABCG1 gene might be associated with the susceptibility and severity of CAD in Chinese Han population.

Objective To explore the correlation of liver depression grading with estrogen receptor alpha and beta(ERα,ERβ)and G protein-couple receptor 30(GPR30)of the perimenopausal women suffering from non-organic insomnia. Methods A total of 127 perimenopausal women suffering from non-organic insomnia were enrolled into the study. The data collected by four diagnostic methods and the scores of Pittsburgh Sleep Quality Index(PSQI)were used for the scoring and grading of liver depression according to Syndrome Element Differentiation. The mRNA and protein expression levels of ERα,ERβand GPR30 in the mononuclear cells of peripheral blood from the patients were detected with real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB)method respectively. Results (1)The differences of mRNA levels of ERα,ERβ and GPR30 were insignificant among the patients with different degrees of liver depression (P > 0.05). ERα mRNA/ERβ mRNA ratio was decreased with the increase of liver depression grading,the differences being significant (F = 6.710, P < 0.001). (2) The differences of protein levels of ERα, ERβ and GPR30 were insignificant among the patients with different degrees of liver depression (P > 0.05);ERα/ERβ protein gray value ratio was decreased with the increase of liver depression grading, and the differences were significant (P < 0.05) . Conclusion The decline of ERα/ERβ is probably contributed to the pathological basis of liver depression in perimenopausal non-organic insomnia women.

OBJECTIVETo observe whether Xuefu Zhuyu Decoction (XZD) could induce the differentiation of mesenchymal stem cells (MSCs) into cardiac myoid cells, thus seeking for safe and effective inducers.

METHODSThe serum pharmacological method was used to induce. XZD containing serum was prepared. MSCs were isolated and cultured. The serum cytotoxicity was detected by MTT. The third generation of favorably grown cells was selected in this experiment. Cells were divided into three groups, i.e., the vehicle control group, the XZD containing serum induced group, and the 5-azacytidine induced group. Expressions of Desmin and alpha-actin were detected by immunocytochemical staining method.

RESULTSBefore induction protein expressions of Desmin and alpha-actin were negative, and few was weakly positive. There was no statistical difference in the weak positive expression rate among the 3 groups (P > 0.05). After induction protein expressions of Desmin and alpha-actin were negative, and few was weakly positive in the vehicle control group. Protein expressions of Desmin and alpha-actin were positive in the XZC containing serum induced group and the 5-azacytidine induced group. There was statistical difference in the positive expression rate when compared with the vehicle control group (P > 0.05).

CONCLUSIONSXZD played a role in in vitro inducing differentiation MSCs to cardiac myoid cells. It might participate in expressions of Desmin and alpha-actin.
