Objective To investigate the role of P21 protein and XIAP on apoptosis-inducing effect by mevastatin against A549 cell line and its mechanisms. Methods The cells proliferation was detected by MTT assay. The cell cycle distribution and apoptosis induction were evaluated with flow cytometer and electron microscopy. The mRNA expression of P21 and XIAP was measured with reverse transcription-polymerase chain reaction.The protein expression of P21 and XIAP was tested with flow cytometer and Western Bolt respectively. Results Mevastatin inhibited A549 cell survival in a time-dependent and concentration-depended manner. Flow cytometry showed that mevastatin induced G0/G1 phase arrest and caused apoptosis. Mevastatin did not affect P21 expression at both mRNA and total protein level.Concomitantly,P21 protein localized on cellular membrane decreased.Both mRNA and protein expression in XIAP were down regulated by mevastatin. All these effects were reversed by mevalonate.Conclusion Mevastatin can inhibite proliferation,induce apoptosis and interfere with cell progression of A549 through mevalonate pathway. Its mechanisms are explained by decreasing the expression of XIAP mRNA and protern.Targeting HMG-CoA reductase,Mevastatin blocks the isoprenylation of P21 protein which affects its anchorage on the cellular membrane.

Objective To investigate the role of P21 protein and survivin on the cell apoptosis of non-small cell lung cancer (NSCLC) induced by mevastatin. Methods The inhibitory effect of mevastatin on A549 and NCI-H520 cell line was evaluated by MTT assay. The cell cycle distribution and apoptosis induction were determined with flow cytometer and transmission electron microscope. The expression of p21 protein was assessed with flow cytometer. The mRNA expression of p21 and survivin was assessed with RT-PCR. Results Flow cytometry showed that mevastatin induced G_0/G_1 cell arrest in NSCLC cell lines. The results indicated that mevastatin caused apoptosis in concentration-dependent manner. Mevastatin produced no change in expression of P21 mRNA and total P21 protein. Concomitantly, P21 protein localized on cellular membrane was decreased. It was also found that mevastatin suppressed the expression of survivin mRNA in NSCLC cell lines. All these effects were reversed by mevalonate. Conclusions Mevastatin inhibited the proliferation of NSCLC cell lines. Mevastatin exerts growth inhibitory effect and induces apoptosis effect by inhibiting mevalonate synthesis. Its mechanisms might involve blockade of the isoprenylation of p21 protein and down-regulation of the expression of survivin mRNA.

Background and purpose:MicroRNAs (miRNAs, miR) are directly involved in cancer initiation, progression and metastasis. Alterations of miRNAs expression in cancer tissue may be reflected in circulation. We attempted to investigate the expression and clinical signiifcance of plasma miR-221 in patients with small cell lung cancer (SCLC). The plasma and tissues levels of miR-221 in 51 SCLC patients and 20 controls were evaluated and compared among various clinicopathological characteristics. Methods: Confirmation of higher miR-221 levels in primary SCLC tissues than normal lung tissues. Evaluation of plasma miR-221 concentrations by comparing results from 51 consecutive SCLC patients and 20 healthy volunteers. Evaluation of the assay for monitoring tumour dynamics in SCLC patients. Results:Expression of miR-221 was signiifcantly higher in SCLC tissues than in para-carcinoma tissues and normal lung tissues. Plasma miR-221 concentrations were signiifcantly higher in SCLC patients than those in normal people (P<0.05). The expression of plasma miR-221 was not associated with gender, and age (P>0.05), correlated with significantly chemosensitivity, overall survival and clinical stage (P<0.05). Cox regression analysis indicated that plasma miR-221 expression and disease stage were found to be significantly independent prognostic factors for the SCLC patients. Conclusion: Plasma miR-221 could be a useful biomarker for cancer detection, monitoring tumour dynamics and predicting malignant outcomes in SCLC patients, and may contribute to clinical decision making in treatments.

To monitor the 24 h esophageal pH in patients with gastroesophageal reflux-induced cough (GERC) before and after omeprazole treatment. Methods The prospective study was conducted in Department of Gastroenterology, People's Hospital of Wuhan University from February 2007 to April 2008. Twenty patients with GERC received 40 mg of omeprazole daily and underwent 24 h esophageal pH monitoring before and 8 weeks after omeprazole treatment. Six parameters by Johson and Demeester were adopted for evaluation: pereentage of total time with pH <4, percentage of uptight reflux time with pH <4, percentage of supine reflux time with pH < 4, the number of reflux episodes with pH < 4, the number of reflux episodes longer than 5 min and the percentage of longest reflux duration. Results The values of six parameters before treatment were 13.5±8.5, 12.2±4.0, 15.8 ±4.1, 56 ± 13, 4. 15 ± 1.87 and 26.2 ± 16. 5 respectively; while those after treatment were 2.7± 1.3, 3.9 ± 1.9, 1.9 ± 1.0, 18 ± 11, 1.24 ±0.65 and 7.4 ± 2. 1. There were significant differences in these six parameters between pre-treatment and post-treatment (P<0.01 ). Conclusion The 24 h esophageal pH monitoring shows that omeprazole is effective in treatment of GERC by decreasing esophageal pH.

Objective To explore the value of transthoracic echocardiography(TTE) and 64-slice spiral computed tomography(CT) in the diagnosis of complex congenital heart disease(CHD). Methods Ninety-seven patients diagnosed as CHD by TTE underwent 64-slice spiral CT for cardiovascular examination. The results were compared with the results by cardiovascular angiography and from surgery. Results The total diagnosis accordance rated by TEE was 90. 2% and that by spiral CT was 92.5%. There was no difference in diagnosis accuracy rate between TTE and spiral CT. The diagnosis accuracy rate in intracardiae defomities by TTE was 99.2 %, higher than 87.50% by spiral CT. However, the diagnosis accuracy rate in extracardiac defomities and ventricular-arterial connections was 99. 0% by spiral CT, higher than 78. 6% by TTE. The combination of TTE and spiral CT can raise the diagnosis accuracy rate to 99. 1%. Conclusions TTE is of significant value in complex CHD diagnosis,especially in the diagnosis of intracardiac defomities. The combination of TTE and spiral CT can raise the diagnosis accuracy rate of various kinds of complex CHD.

Objective To investigate the polymorphism at positions-137 and -607 in the upstream promoter 1 region of exon 2 of interleukin(IL)-18 gene in Han children with atopic dermatitis(AD)in Chongqing,China,as well as its correlation with the development of AD.Methods Blood samples were collected from 82 patients with atopic dermatitis and 100 healthy controls.DNA was extracted from the samples and subjected to test with PCR.The polymorphism of IL-18 gene at positions-137 and -607 in the upstream promoter 1 region was analyzed by polymerase chain reaction(PCR)-sequence specific primers(SSP)and gene sequencing.Genotype frequency was compared between the patients and controls.Resuits A G/C polymorphism(GG,GC and CC genotypes)was identified at position-137 in exon 2 of IL-18 gene,and a C/A polymorphism(CC.CA and AA genotypes)at position-607 of this gene.The frequency of genotype GC at position-137 was significantly higher in the patients than that in the controls(47% vs 27%,P＜0.05;odds ratio=2.33.95% confidence interval 1.26-4.33).Increased frequency of C allele was also noted at the position-137 in the patients compared with the controls(0.24 vs 0.15,P＜0.05;odds ratio=1.76,95% confidence interval 1.04.2.97).Patients with severe AD(SCORAD score＞50)were more likely to carry C allele at position-137 of IL-18 gene than those with mild AD(SCORAD＜20).There was no statistical difference in allele frequency at -607(C/A)among patients with mild,moderate,severe AD and the controls(P＞0.05).Conclusions There is a polymorphism at positions -137 and -607 in the upstream promoter 1 region of IL-18 exon 2.The GC genotype of IL-18 at position -137 may confer the susceptibility to AD in Han children in Chongqing.
