Objective To evaluate the clinical value of co-observation of the expression of MAGE-A3 gene and MDR1 gene on esti-mating the curative effect in non M3-subtype acute leukemia. Methods Expressions of MAGE-A3 and MDRI were measured in 77 patients with non M3-subtype acute leukemia by RT-PCR method. Clinical observation was done to estimate the relationship between the genes with curative effect in non M3-subtype acute leukemia. Results Expression of MAGE-A3 and MDRI gene were 50. 6% and 23. 3% in non M3-subtype acute leukemia patients. Positive expression of MDRI in MAGE-A3-positive and negative patients were 46. 2% and 13. 2% (P < 0.01). The complete remission rate in MAGE-A3 negative and positive patients were 86. 8% and 64. I% (P <0. 05). Complete remission (CR) rate in MDR1 negative and positive patients was 83.3% and 56. 5% (P <0. 05). Complete remission rate were 87.9% and 55.6% in beth negative and both positive expression of MAGE-A3 and MDR1 (P < 0. 05). Conclusion The patients of positive expression of MAGE-A3 in non M3-subtype AL had higher expression of MDR1. The patients with negative expression of beth MAGE-A3 and MDR1 had higher CR rate than that in both positive patients. These researches indicated that eo-observatian of the expression of MAGE-A3 and MDR1 can predict the curative effect in non M3-subtype AL.

Objective To summarize the experience of modified Nuss procedure with thoracoscope for the correction of pectus excavatum in children. Methods Forty-nine pediatric pectus excavatum were treated by modified Nuss procedure with thoracoscope from August 2006 to July 2008, the age ranged from 3 to 18 years, 36 patients were symmetric pectus excavatum and 13 patients were asymmetric pectus excavatum. Results The operations in all patients were successful. Only 1 case used two bars,other 48 cases used one bar. There were no major complications such as cardiac perforation occurred during the operation. The earlier complication was pneumatothorax in 1 case, and the average blood loss was less than 10 ml. The postoperative hospital length of stay was 6-8 days. All patients had a satisfied deformity correction and no needs of transfusion. Therapeutic results evaluation showed excellent in 43 patients and good in 6 patients. All patients were followed up in 0.5-23.0 months without bars displacement, 1 ease had chronic intermittent pain for 2 months. The bar had been removed in 1 case after operation 23 months who still kept in excellent result. Conclusions Modified Nuss procedure is easy to performed with minimal invasion and satisfied deformity correction. Thoracoscopic visualization facilitates the safety of this technique.

Objective To explore the influence of high fat diet on the intestinal gene expression profile in C57BL/6 mice. Method C57BL/6 mice were randomly assigned to two groups (n=8). The control group consumed an ordinary diet. The experimental group was fed with a high fat diet. All mice were sacrificed at the end of 6 w and the intestinal gene expressions were detected by oligonucleotide microarray analysis with Affymetrix GeneChip Mouse U430A consisting of 13 097 genes. Results Among the 13 097 genes obtained from gene expression profile analysis, there were 88 and 179 genes up -and down-regulated respectively, in mice fed with high fat diet compared with the control. The differentially expressed genes were mainly related to free radical oxidative stress, DNA repair, induction of apoptosis, transport, signal transduction and inflammation immune response. Conclusion High fat diet may widely modulate the expression of many genes in the intestine in mice.

ObjectiveTo investigate the clinical efficacy of heat-sensitivepoint Yaoyangguan(GV3)moxibustion for sciatica and preliminarily explore the mechanism of its action.MethodOne hundred and twelve sciatica patients were randomly allocated to heat-sensitive point Yaoyangguan moxibustion (observation), non-heat-sensitive point Yaoyangguan suspended moxibustion (control) and medication groups. The observation group received heat-sensitive point Yaoyangguan moxibustion; the control group, non-heat-sensitive point Yaoyangguan suspended moxibustion; the medication group, oral administration of Yaobitong capsules. The clinical symptoms were scored, the Pain Rating Index (PRI), the Visual Analogue Scale (VAS) and the Present Pain Intensity (PPI) scores were counted and serum IL-8 content was measured in the three groups beforeand after 15 days of treatment.ResultAfter 15 days of treatment, all the three treatments had a certain therapeutic effect on sciatica. The therapeutic effect was bestin the observation group (P<0.05). The PRI, VAS and PPI scores and serum IL-8 contentdecreased in all the three groups compared with before treatment (P<0.05) and were lower in the observation group than in the control and medication groups (P<0.05). There was no statistically significant difference between the control and medication groups (P>0.05).ConclusionHeat-sensitive point Yaoyangguan moxibustion has a better therapeutic effect than non-heat-sensitive point Yaoyangguan suspended moxibustion and oral administration of Yaobitong capsules. This method is an ideal treatment for sciatica. The mechanism may be related to a posttreatment decrease in inflammatory factors in the diseased region.

AIM:To elucidate the molecular mechanisms of lipoic acid (LA) on redox regulation and digestive function in intestine of C57BL/6 mice fed high fat diet (HFD).METHODS:C57BL/6 mice were randomly assigned to one of three groups (n=8). The control group consumed an ordinary diet. The other two experimental groups were fed with a high fat diet,high fat plus 0.1% LA. After 6 weeks,the activities of digestive enzymes were examined. In order to evaluate the antioxidant status of the mice,superoxide dismutase (SOD),malondialdehyde (MDA),total antioxidant capacity (TAC) and reactive oxygen species (ROS) in intestinal homogenate were measured. To investigate the molecular mechanisms underlying the effects of LA,the gene expression profiles in intestine were examined using the GeneChip microarray system.RESULTS:A depressed antioxidant defense system,accompanied by digestive and absorptive function impairment,was observed in HFD-fed mice. These changes were partially restored in the LA-treated group. DNA microarray analysis of intestine showed that LA ingestion up-regulated the expression of genes related to free-radical scavenger enzymes,digestive enzymes and transporters.CONCLUSION:Treatment with LA improves redox homeostasis and the function of intestine in mice fed HFD. The mechanism may involve preventing oxidative stress by scavenging ROS directly and increasing those of free-radical scavenger enzymes gene expression indirectly.
