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.

METHODS:27 ADR reports induced by Magnesium isoglycyrrhizinate injection from Hunan Center for ADR Monitoring from Jan. 2014 to Mar. 2015 were retrospectively analyzed. RE-SULTS:In the 27 cases,15 were male (55.56%) and 12 were female (44.44%),with percentage of 1.25∶1;ADR mainly oc-curred in patients with 41-60 years old(51.85%);involved organ/system were mainly skin and its appendages(35.85%)and sys-temic damage(26.42%),the main clinical manifestations were rash,itching,fever,chills,vomiting and dizziness;there were 7 severe ADR reports(25.92%),mainly showed chills,fever and other systemic symptoms;most ADR can be cured(40.74%)or relieved(55.56%)by related processing. CONCLUSIONS:There are no risk tips for severe allergic reactions in instruction,it is necessary to strengthen post-marketing surveillance and further improve the drug instructions to reduce the risk of severe ADR in-duced by Magnesium isoglycyrrhizinate injection.

OBJECTIVE:To optimize the extraction technology of polysaccharides from antlion and explore its effect on im-mune functions of mice. METHODS:Using content of polysaccharides as investigation index,the effects of extracting polysaccha-rides from antlion by water extraction method protease hydrolysis extraction(optimized by orthogonal test using extraction tempera-ture,enzyme dosage,extraction time as indexes),and diluted alkali extraction(optimized by orthogonal test using alkali concentra-tion,extraction temperature,extraction time as indexes)were compared. 128 KM mice were randomly divided into 4 groups,then randomly divided into control group(normal saline),polysaccharides low-dose,medium-dose,high-dose groups(20,40,80 mg/kg),8 in each group,iv in tail vein,0.2 mL/10 g,once a day,for 1 week,which were respectively used to determine the phago-cytosis percentage and phagocytic index of peritoneal macrophages,spleen and thymus index,lymphocyte transformation rate and serum hemolysin levels. RESULTS:The contents of polysaccharides by 3 methods were 14.48%,38.66%,30.62%,respectively. The content of polysaccharides by protease hydrolysis extraction was the highest,the optimal extraction technology were as follows as using 100 μg/g papain extracting 3 h under 40 ℃. Compared with control group,phagocytosis percentage,phagocytic index, spleen index in polysaccharides low-dose,medium-dose,high-dose groups were significantly increased (P<0.05),thymus index was significantly decreased(P<0.05),while lymphocyte transformation rate had no significant changes(P>0.05);serum hemoly-sin in polysaccharides medium-dose group was significantly increased (P<0.05). CONCLUSIONS:Protease hydrolysis extraction is suitable for the extraction of polysaccharides from antlion,the optimal technology is reliable. Polysaccharides from antlion show activity in enhancing mice non-specific immunity and humoral immunity.
