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.

The childhood asthma is characterized as high morbidity,recurrent attack,chronic persistence and refractoriness. So asthma with these features mentioned above can have important effect on children′s emo-tional and physical development as well as their families. This review sketches the studies of children asthma family management present situation and its influencing factors,and stresses the necessity of asthma family man-agement. Methods of psychotherapy used in our country and abroad and its implementation effect are reviewed, including behavior therapy,cognitive therapy,cognitive behavioral therapy,relaxation therapy,family therapy and other existing psychological treatment,in order that these measures can be conductive to the development of pre-vention methods of pediatric asthma and further researches.

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.

Colorectal cancer is one of the most common malignancies in the world, and rectal cancer accounts for a large percentage of this disease in Chinese patients. Surgical extirpation is the mainstay of therapy, Intraluminal ultrasound is highly accurate in detecting depth of invasion and lymph node metastasis, and is also helpful in preoperative staging of rectal cancer. Preoperative adjuvant therapy could down-stage tumors, improve the radical resection rates of advanced lower rectal cancer, increase the rate of sphincter-saving surgery, and decrease the local recurrence rate. Total mesorectal excision could signifi-candy decrease the local metastasis of rectal cancer, and rectal cancer resection with preservation of pelvic autonomic nerve is effective in preventing urinary or reproductive dysfunction. Recently, minimally invasive surgery has been introduced for the management of rectal cancer, and transanal endoscopic microsurgery is a new method with advantages in rectal cancer treatment.

Objective: To study the relationship between endoplasmic reticulum stress (ERS) and adiponectin;to explore the role of ERS for increasing myocardial ischemic vulnerability in type 2 diabetes mellitus (DM) mice.
Methods: Type 2 DM model was established by high fat diet with streptozotocin (STZ) injection. A total of 35 C57BL/6J male type 2 DM mice were divided into 4 groups: ①Control group, n=5. ②Tauroursodeoxycholic acid (TUDCA) group,③Thapsigargin (TG) group and ④Normal saline group. The mice in Groups ②, ③, ④were fed by high fat and high glucose diet by injecting streptozotocin (STZ), in the last 3 weeks and respectively received intraperitoneal injections of TUDCA (250 mg/kg), thapsigargin (TG) (300μg/kg) and normal saline twice a day, n=10 in each group. Then myocardial infarction (MI) model was established in 5 mice from each group. 72 hours later, the MI ranges were measured, serum levels of adiponectin were detected, mRNA expressions of adiponectin and CHOP in myocardial tissue were examined.
Results: The MI range in TUDCA group (21.47 ± 2.85)%and in Normal saline group (39.92 ± 4.28)%were both lower than TG group (66.56 ± 8.15)%, both P<0.01. Before MI occurrence, serum levels of adiponectin in TUDCA group (79.25 ± 6.40) pg/ml and in Normal saline group (70.23 ± 4.15) pg/ml were both higher than TG group (62.64 ± 5.70) pg/ml, both P<0.01;serum levels of adiponectin in each group were higher than they were 72 h after MI. In each group, the mRNA expression and protein content of adiponectin in myocardial tissue were constant to serum adiponectin;while the mRNA expression and protein content of CHOP was opposite to serum adiponectin.
Conclusion: ESR could increase myocardial vulnerability in type 2 DM mice which might be related to down-regulating adiponectin expression.
