ObjectiveTo investigate and analyze the factors affecting the quality of life of patients with gastric cancer after surgery. Methods120 cases of gastric cancer patients undergoing resection of gastric cancer from March 2009 to March 2010 in our hospital were chosen as the research object.100 cases of non-cancer patients with similar general information and without factors affecting quality of life at the same period were chosen as the control group.Quality of Life Questionnaire of Stomach 22 (QLQ-STO22) were used to investigated the quality of life of patients in the two groups.The factors affecting the quality of life for patients with gastric cancer were analyzed.Countermeasures to increase the quality of life of cancer patients were explored according to factors affecting the quality of life. ResultsThe study showed that quality of life of gastric cancer patients was significantly lower than the control group.The differences were significant.Multiple linear regression analysis showed that gender,age,personality,education degree,family economic status,cancer disease were the main factors affecting their quality of life. ConclusionsIn clinical care of patients with gastric cancer,the medical staff should take appropriate psychological care and health education based on individual circumstances of patients,try to eliminate the adverse fractors of patients in psychology,cognition and thought in order to enhance the quality of life of patients after surgery.

BACKGROUND:There are few reports about the effect of serum-free culture on the differentiation of rat adipose-derived stem cel s into vascular endothelial cel s.
OBJECTIVE:To investigate the isolation, serum-free culture of rat adipose-derived stem cel s differentiating into vascular endothelial cel s.
METHODS:The rat adipose-derived stem cel s were isolated from male Sprague-Dawley rats and expanded to the third passage by enzymatic digestion-adherent explants method. In the experimental group, rat adipose-derived stem cel s were cultured in serum-free medium for 24 hours. In the control group, rat adipose-derived stem cel s were cultured in low-glucose Dulbecco’s modified Eagle’s medium containing 10%fetal bovine serum. After that, the cel s were cultured in inducing medium for 3 weeks to differentiate into vascular endothelial cel s.
RESULTS AND CONCLUSION:The rat adipose-derived stem cel s grew as polygonal or fusiform-shaped adherent cel s when cultured in vitro, which could stably proliferate and passage. The rat adipose-derived stem cel s showed very low expression of CD31, a cel surface marker, after passages. After directional differentiations into vascular endothelial cel s, the cel s were pebble-shaped under the inverted microscope. Expression of CD31 was up-regulated, which was much higher in the experimental group than the control group. The induced cel s in the experimental group had stronger abilities than those in the control group to swal ow Dil-labeled acetylated low-density lipoprotein and form tube-like structures on the matrigel after differentiation into vascular endothelial cel s. So, rat adipose-derived stem cel s could be highly successful y induced to differentiate into vascular endothelial cel s in vitro after serum-free culture.

AIM: To study the role of c-Jun NH_2-terminal kinase (JNK) in the development of insulin resistance induced by tumor necrosis factor-α (TNF-α) or H_2O_2 in 3T3-L1 adipocytes. METHODS: Differentiated 3T3-L1 adipocytes were pretreated with JNK1 small interfering RNA (siRNA) or JNK inhibitor SP600125, then exposed to 1 nmol/L of TNF-α or micromolar H_2O_2 generated by adding glucose oxidase (50 U/L) to the medium for 12 h. The cellular glucose uptake was determined by radioactive method. RESULTS: Compared to control adipocytes, 12 h incubation with TNF-α or H_2O_2 led to 50%-55% reduction (P<0.01) of the insulin-dependent glucose uptake. JNK1 siRNA transfection significantly inhibited JNK1 expression and blocked the TNF-α or H_2O_2-induced impairments of cellular glucose uptake. Pretreatment with SP600125 (20 μmol/L) resulted in significant increases in insulin-stimulated glucose uptakes in both TNF-α (66%) and H_2O_2 (62%) treated adipocytes (P<0.01). CONCLUSION: JNK plays a key role in TNF-α or H_2O_2 induced insulin resistance in 3T3-L1 adipocytes, and inhibition of JNK over-activation may be a new therapeutic target for insulin resistance.

The common respiratory pathogens which can cause children kidney disease include bacteria,viru-ses,mycoplasma pneumonia,and so on,the major clinical manifestations of infectious renal injury are glomerular nephri-tis,nephrotic syndrome,interstitial nephritis and renal subclinical glomerulonephritis. Group A β - hemolytic streptococ-cus is the most common cause of acute glomerulonephritis in children(50% - 90% ). Mycoplasma pneumoniae infec-tions and respiratory tract virus - associated renal injury are the important part of kidney disease in children with acute non - streptococcal infection,and comparing with the streptococcal glomerulonephritis,the process and prognosis of my-coplasma and virus infection are relatively better,and the level of blood urine,hypertension and serum complement is lower,with shorter duration and rapid recovery,and the duration of edema and proteinuria in children with nephrotic syndrome is shorter as well. There may be similar genetics and immunology pathogenesis between virus - induced wheezing or asthma and kidney injury in children.
