Objective To explore the effect of nuclear factor-kappaB(NF-?B) on cardiac myocyte apoptosis and understand the molecular mechanism of decrease of heart function in septic shock rats.Methods Twenty Wistar rats were randomly divided into the septic shock group and the normal control group.The septic shock group(n=10) were fixed with anaesthesia and made into 1.5 cm slices just along the abdomen midline.Then the roots of appendices were returned to the belly cavity after being ligated and punctured 4 times with the No.14 pinhead.After that,the slices were sewn up layer by layer.After 12 hours,the rats were all sacrificed,the blood taken and the serum separated.In the end,the heart specimens of the septic shock group were set aside.Meanwhile,the normal control group were dealt with in the same way except that they were not subjected to cecal ligation and puncture.Then NF-?B protein levels in cardiac tissue and the index of cardiac myocyte apoptosis were measured.Results NF-?B protein levels in the septic shock group(9 cases were strong masculine gender,1 case was middle masculine gender)elevated significantly compared with the normal control group(8 cases were negative gender,2 cases were weak masculine gender) in cardiac tissue(P

OBJECTIVETo study the distribution of different genotypes of CYP2C19 in multiple myeloma (MM), and investigate the effect of its polymorphism on efficacy of thalidomide-based regimens for the treatment of MM and discuss the role of antiangiogenesis in MM.

METHODSThe CYP2C19 genotype of 92 patients with multiple myeloma was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The incidence of poor metabolizer (PM) in MM was compared with that in healthy Chinese people. After they were treated with thalidomide-based regimens, the response rate was compared between extensive metabolizers (EMs) and PMs.

RESULTSOf 92 patients, 18 (19.5%) were PMs, which was comparable to that in healthy ones. The response rates in EMs and PMs were 62.6% and 33.3%, respectively (P < 0.05). When patients were grouped by treatment regimens, the response rate in EMs was significantly higher than that in PMs (60.8% vs. 27.3%) for the thalidomide-dexamethasone group, and similar results were observed for the thalidomide-chemotherapy group (65.2% vs. 42.7%) though there was no statistical difference (P > 0.05).

CONCLUSIONCYP2C19 genotype has no difference between MM patients and healthy person, but exhibits an effect on the treatment efficacy of thalidomide for MM. The lower response rate observed in PMs is possibly due to the reduced activity to inhibit angiogenesis by thalidomide.

To establish neonatal rat cardiac fibroblast inflammatory secretion model by using LPS 100 microg x L(-1) combined with ATP 5 mmol x L(-1), in order to study the inhibitory effect of quercetin on the secretion of inflammatory factors TNF-alpha, IL-1beta and IL-6 of cardiac fibroblasts, further investigate the effect of quercetin on the protein expression of p-NF-kappaB p65 (S276) and p-Akt (S473) by western blot, and discuss the inhibitory effect of quercetin on the inflammatory secretion of cardiac fibroblasts. According to the findings, quercetin with the concentrations between 51.74 micromol x L(-1) and 827.81 micromol x L(-1) had no significant effect on the activity of cardiac fibroblasts. Quercetin with the concentrations of 82.78, 41.39, 20.70 micromol x L(-1) could notably inhibit the increase of TNF-alpha and IL-1beta induced by LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 36 h (P < 0.01 or P < 0.05). Quercetin with the concentrations of 82.78, 41.39 micromol x L(-1) could notably inhibit the increase of IL-6 induced LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 36 h (P < 0.05), without any notable effect of quercetin with the concentration of 20.70 micromol x L(-1). Quercetin with the concentrations of 82.78, 41.39, 20. 70 micromol x L(-1) could notably inhibit the NF-kappaB p65 (S276) activation induced by LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 15 min, with the most significant effect in 20.70 micromol x L(-1). Quercetin with the concentrations of 82.78, 41.39, 20.70 micromol x L(-1) could notably inhibit the increase of p-Akt(473) expression induced by LPS 100 microg x L(-1) for 3 h and then ATP 5 mmol x L(-1) for 240 min (P < 0.05). Therefore, this study believes that quercetin could attenuate the secretion of inflammatory factors TNF-alpha, IL-1beta and IL-6 of cardiac fibroblasts by inhibiting the activation of NF-kappaB p65 (S276) and Akt (473).

Teaching is an art,which requires teachers to have high profession level and better ability of language expression.To stress teaching techniques is the request of higher medical science education.It is worth summarizing and thinking seriously.This article summarized several aspects of teaching techniques,essence.In addition,it explained the significance of teaching techniques.

Pure culture of Phlebopus portentosus was inoculated in the roots of coffee tree. The results indi-cated that the young fruit bodies would come out around the rhizomes of host tree after inoculation in 30 to 90 days, single or cluster, 3 to 4 days for mature, weight 20.0 g to 62.0 g. Brown rhizomorph and hyphae can be seen on the seedlings`rhizome, main root and side root while nothing is on the tip of the root.It was found that rhizomorph on the surface of roots would die after inoculation in 90 days in pot.

Objective To evaluate the clinical parameters that can predict whether a patient can get significant improvement at the 10th week,or whether a patient can have an extended length of remission after discontinuing the infusion in ankylosing spondylitis(AS)patients treated with three standard infusions of in- fliximab.Methods Sixty-three AS patients were given three infusions of 5 mg/kg of infliximab at week 0,2 and 6;and were evaluated serially before each infusion and week 10.Afterwards.patients were followed by telephone interview until their disease activity was≥60% of the baseline level.At that point,disease was con- sidered to relapse.Clinical parameters at baseline as well as at week 2 were used to identify factors which might predict an improvement at week 10,or predict a delayed relapse.A predictor was regarded as being use- ful if the area under the curve(AUC)more than 0.75 when analyzed by receiver operator calculations(ROC). Results No parameters at baseline have sufficient predictive value.However,ASAS20(Assessment in Anky- losing Spondylitis International working Group criteria)at week 2 predicts improvement at week 10.and also duration of remission after discontinuing the infliximab at week 6.Conclusion The response to one pulse of infliximab is the best predictor of subsequent response as well as rate of relapse after discontinuing the inflix- imab.

Objective　To evaluate the role of transfected angiotensinⅡ(Ang Ⅱ) receptor AT1 anti-sense nucleotide (AT1A) in the expression of subtypes of AngⅡ receptor mRNA, synthesis of protein and nucleic acid in cardiomyocytes. Methods　AT1 cDNA sequence (476 bp) was cloned with RT-PCR and reversely inserted into PcDNA3.1 (5.4 kb) to construct an intact plasmid containing AT1A (PAT1A). The plasmid was then transfected into the cultured cardiomyocytes and identified with RT-PCR and Western blot. The synthesis of protein and nucleic acid identified by 3H-Leu and 3H-TdR incorporation, and expressions of AT1 and AT2 mRNA by RT-PCR, were compared between transfected and nontransfected cardiomyocytes after being stimulated with 10-7 mol/L AngⅡ for 24 h. Results　The plasmid PAT1A were successfully constructed. The AT1 mRNA and its protein were expressed significantly less in the transfected cardiomyocytes than in the control (P<0.01). In the transfected cardiomyocytes, AT1 mRNA expression was markedly decreased, but that of AT2 mRNA obviously increased (P<0.01) when compared with the nontransfected cardiomyocytes after stimulation for 24 h with AngⅡ 10-7 mol/L; no significant difference was found in 3H-Leu and 3H-TdR incorporation between them. Conclusion　After the cardiomyocytes was tranfected with AT1A, the expression of AT1 mRNA was markedly suppressed，while AT2 mRNA up-regulated at the same time. Our results indicate that AT1A blocking can not effectively interrupt the Ang Ⅱ-induced synthesis of the protein and nucleic acid in cardiomyocytes.
