A variety of molecular markers are related to the prognosis of gastric cancer,such as the the loss expression of AT rich interactive domain 1A (ARID1A),the overexpression of CD133 and survivin are releated to the incidence and poor prognosis of gastric cancer; leptin,CD44 and microRNA (miRNA) are releated to the invasion and metastasis of gastric cancer; the low expression of secreted protein acidic and rich in cysteine (SPARC) contributes to the angiogenesis of gastric cancer,but the relationship between SPARC and prognosis needs further study; the expression and gene polymorphism of excision repair cross-complementing 1 (ERCC1) may be useful for choice of medication in the treatment of gastric cancer.

Objective To observe the selective regulation of peroxisome proliferator-activated receptors (PPAR) on fatty acid binding protein-4 (FABP4) in human syncytiotrophoblasts.Methods Cultivate normal human syncytiotrophoblast cells,and put in the specific antagonists and agonists of PPAR each subtypes receptors,then observe the different expression of FABP4 mRNA and protein.Results Pretreated the human syncytiotrophoblast cells with the agonists (GW7647,GW0742) and antagonists (GW6471,GSK0660) of PPARα and PPARβ receptors,the expression of the FABP4 was not significantly change (P＞0.05).However pretreated with PPARγ agonists (rosiglitazone,1 × 10-9,1 × 10-8,1 × 10-7 and 1 × 10-6 mol/L),the expression of FABP4 mRNA and protein could be dose dependent-promoted significantly (mRNA:1.27 ±0.12,1.45 ±0.14,1.57±0.14,1.72 ±0.12,protein:1.10 ±0.08,1.37 ±0.09,1.60 ±0.13,1.79 ± 0.14 ; P ＜ 0.05),furthermore,the promotion can be dose dependent-reversed by specific antagonists GW9662 (mRNA:0.92 ± 0.06,0.77 ± 0.06,0.64 ± 0.05,0.55 ± 0.05,protein:0.91 ±0.03,0.78 ±0.06,0.70±0.07,0.55 ±0.06; P ＜ 0.05).Conclusions In normal human syncytiotrophoblast cells,FABP4 is a target factor of PPARγ.PPARγ regulated the expression of FABP4 mRNA and protein selectively.And the regulation will not be influenced by the other two PPAR subtypes.

Helicobacter pylori is able to colonize the human stomach and dwell in the human stomach for decades or for whole lifetime. A number of potential virulence factors contribute to Helicobacter pylori to colonize this unusual niche. Motility is an essential colonization factor based on the fact that nonmotile variants of Helicobacter pylori can't infect gnotobiotic piglets. Motility is not a colonization factor based on rapid loss of motility of Helicobacter pylori in the gastric lumen in vivo. The exact roles of Helicobacter pylori motility are not yet known. The aim of this article is to discuss correlation between colonization and motility of Helicobacter pylori.

Mucopolysaccharidosis type Ⅱ is a rare single gene inherited disorder. In the earlier studies, more attention was paid to the molecular analysis of the hot spots of the mutations. With the detection of more and more novel mutations,more studies are trying to analyze the effect on splicing of different types of mutations and the genotype-phenotype correlations. This review will introduce the progress on molecular genetics, the gene mutation,analysis of the female patients and the genotype-phenotype correlations. With the study of these progress,it suggested that more attention should be paid to the possibility of gene-pseudogen recombinations, trying to study the effect on splicing from the cDNA level, which will benefit the investigation of the genotype-phenotype correlations.

Objective To investigate the relationship of obesity with metabolic syndrome.Methods Six hundred and ninety-seven patients were chosen from the routine physical check-up from 2003 to 2005.These cases were divided into three groups according to body mass index(BMI).The detection rate of high triglyceride(TG) and low level of high-density lipoprotein cholesterol(HDL-C) were compared among groups of different BMI levels.The detection rate of hyperglycemia,hyperuricemia and high blood pressure among groups of different BMI levels was compared.Results With BMI increasing,the detection rate of high TG and low HDL-C also increased.The difference among three groups was statistically significant(P

Objective To investigate the effect of intraperitoneal injection of compound sophora injection in the treatment of advanced gastric cancer patients with malignant peritoneal effusion.Methods 60 advanced gastric cancer patients with peritoneal fluid were randomly divided into two groups according to the different treatment meth-ods.A group of compound sophora injection with intraperitoneal therapy(group A),treatment 2 times per week for four weeks,Another group of compound sophora injection with vein therapy (group B),for 4 consecutive weeks.The efficacy of the two groups was compared.Results The effective rate of group A was 58.1%,which was higher than 27.6% of group B,the difference was statistically significant(χ2 =5.69,P <0.05).Conclusion Intraperitoneal perfusion with compound sophora injection can improve the effect in the treatment of peritoneal effusion in patients with advanced gastric cancer,and the adverse reaction is mild,it is worthy of clinical application.

[Summary] Glucose homeostasis is precisely regulated by glucagon of pancreaticαcell and insulin ofβcell secretion.Diabetes is a chronic disease characterized by insulin deficiency or insulin resistance (IR). Absolute or relative excess of glucagon secretion may play an important role in the development of diabetes.Previously more studies on the functions of islet βcells were reported,but less on islet αcells. There are a variety of factors involved in the regulation of glucagon secretion,such as nutrients,endocrine hormones and neurotransmitters. High fasting and postprandial blood glucose in patients with diabetes are associated with increased glucagon.Isletαcell dysfunction is closely related to the development of diabetes and the ability of responding to hypoglycemia.Further studies of α cell function and its role on the development of diabetes could provide insight into the treatment of diabetes.
