BACKGROUND:In oral warm and moisture circumstance, al oy which contains Be is easily to be eroded to release Be2+. But there is stil no research focusing on beryl ium influence on genotype of Porphyromonas gingivalis fimbriae gene cluster. OBJECTIVE:To investigate Be 2+effect on genotype of Porphyromonas gingivalis fimbriae gene cluster. METHODS:The revived Porphyromonas gingivalis was resuscitated for 48 hours in the anaerobic culture medium with different concentration of Be 2+(10×10-6, 5×10-6, 1.25×10-6). Through PCR amplification and sequencing, we investigated the effects of Be2+RESULTS AND CONCLUSION:(1) When Be on genotypes of Porphyromonas gingivalis fimbriae gene cluster. 2+concentration was 5×10-6, we found the peak of 217 and 257 sites on DNA sequence expressing G/A overlap peak, different from G single peak of the other groups, suggesting the suspicious bases changes, part of the single base G mutated into A. (2) On al concentrations, we found a base group composed of seven A bases was inserted into the 101 site of DNA sequence. Up to now, there is no direct contacts of the mutations occurring to Be2+concentration. Changes of gene may lead to the shifting of the reading frame, the abnormal synthesis of proteins, the change of Porphyromonas gingivalis fimA gene toxicity, and lastly the unbalance of the micro-ecological environment.

Objective To justify the clinical use of traditional Chinese materia medica (TCMM) in the treatment of influenza.Methods The literature on treatment of influenza published before December 31, 2013 was searched in MEDLINE, EMBASE, CBMdisk, Chinese National Knowledge Infrastructure (CNKI) and Wanfang Database.Results A total of 7 randomized controlled trials were identified and reviewed. Based on the meta-analysis, Yinqiao Powder prescription had similar effect to oseltamivir in defervescence [WMD=5.66, 95%CI (-32.02, 43.35), P=0.77] and viral shed-ding [WMD=-6.21, 95%CI (-84.19, 71.76), P=0.88], and Lianhuaqingwen also had similar effect in viral shed-ding [WMD=-0.24, 95%CI (-4.79, 4.31), P=0.92] but was more effective in defervescence [WMD=-4.65, 95%CI (-8.91, -0.38), P=0.03].Conclusion TCMM has a potential positive effect in the treatment of influenza.

Objective To investigate the difference of short-term clinical efficacy between decompressive laminectomy into In-Space and simple decompressive laminectomy for treatment of lumbar spinal stenosis with vertebral instability.Methods Thirty-three patients with lumbar spinal stenosis with vertebral instability admired from May 2009 to July 2010,were divided into two groups by random number table.Group A of 16 cases was treated with laminectomy decompression and placement In-Space,group B of 17 cases was treated with laminectomy decompression.Lumbar anteroposterior,lateral and flexion-extension X-ray films,preoperatively,and the follow-up were used to measure anterior and posterior disc height,foraminal height,segmental lordotic angle at surgical level.Using Oswestry disability index (ODI) and the visual analogue scale (VAS) to evaluate the clinical efficacy.Results All patients were followed up for (13.20 ± 2.91 ) months (range 6 to 21 months).The anterior disc height after operation of group A was slightly decreased compared with the preoperative(P＞ 0.05 ),the posterior disc height at 1 day after operation and foraminal height after operation of group A were significantly increased compared with the preoperative (P＜ 0.05).The anterior and posterior disc height,foraminal height of group B at 1 day,1 month,3 months after operation were no significantly different compared with the preoperative (P ＞ 0.05 ),at 6 months after operation and the end of follow-up were significantly decreased compared with the preoperative or 1 day after operation (P ＜ 0.05 ).Activity of lumbar vertebra by preoperative 9.86° ± 1.90° decreased to the end of followup 5.60° ± 2.02°in group A,while activity of lumbar vertebra by preoperative 9.89° ± 2.00°increased to the end of follow-up 10.76° ± 3.14° in group B.At the end of follow-up,lumbar back pain VAS,ODI score [ (2.02 ± 1.98 ),( 20.18 ± 18.80) scores ] of group A were significantly lower than those of group B [ (4.15 ±2.36),(30.39 ± 16.62 ) scores ],the differences were statistically significant (P ＜ 0.05 ).No patient suffered In-Space loosening,fracture and emerge.Conclusion The operation of In-Space can maintain spinal mobility and stability as well as avoiding lumbar vertebral instability,and its short-term efficacy is satisfactory.

Macrophage migration inhibition factor(MIF)is an important multifunctional cyto- kine,and it participates in many pathophysiologic processes.A growing body of evidence sug- gests that MIF plays an important role in macrophage-involved regulation of various diseases, especially in atherosclerosis,This article mainly reviews the discovery,structure,sources and biological functions of MIF,particularly the roles in artherosclerosis and its related diseases.

Background Heat shock proteins (HSPs) are highly conserved proteins that are induced in cells when confronted with a wide variety of proteotoxic stresses.HSP27 has a high degree of similarity with α-crystallin protein.The abnormality of HSP27 structure and expression are closely related to the formation of cataracts.Our previous study showed sodium salieylate has the protective effect on H2O2-induced lens damage.Objective This study was to investigate the roles of MAPK signal pathway in sodium salicylate-induced the expression of HSP27 in human lens epithelial cells (LECs) in vitro.Methods Human LECs were incubated in the fresh media containing sodium salicylate at different concentrations (0-55 mmol/L) for different times (1-5 hours) and allowed to be recovered in fresh medium without sodium salicylate for 1-24 hours with or without pretreatment with P38MAPK inhibitor (SB203580), ERK1/2 inhibitor (PD98059) and JNK/SAPK inhibitor ( SP600125). The expressions of P38MAPK, EBK1/2, JNK/SAPK, phosphorylated P38MAPK, phosphorylated ERK1/2, phosphorylated JNK/SAPK and HSP27 were detected by Western blot. HSP27 mRNA was detected by RT-PCR. The expression of HSP27 was also detected by immunohistochemistry. Results There was only weak expression of HSP27 in normal human LECs.After stimulation of 35-55 mmol/L sodium salicylate was removed and human LECs were cultured again for 6 hours,the expression of HSP27 in LECs were significantly increased ( F= 509. 953,P<0. 01). HSP27 was absent expressed in human LECs in 55 mmol/L sodium salicylate stimulation for 1-5 hours groups, but LECs were re-cultured for 3,6 hours after removed the stimulation, the expression of HSP27 was elevated (F = 452. 534, P<0. 01). Activation of P38 M APK occurred after sodium salicylate stimulation 30 minutes and 1 hour ( F = 865.68, P<0. 01). However, ERK 1/2 was expressed after sodium salicylate was eliminated for 1-6 hours ( F = 388.84, P<0. 01). JNK/SAPK was inactived by sodium salicylate. The expression of HSP27 could be down-regulated with the pretreatment of SB203580 and PD98059. Conclusion Sodium salicylatc can induce the expression of HSP27 in human (LECs) . The effects are mediated,at least in part ,through the activation of P38MAPK and ERK1/2 signaling pathway .

Objective To investigate the effects of cognitive interventions (CIs) in the context of communi- ty based rehabilitation (CBR) on cognitive deficits (CDs) in stroke patients.Methods Ninety-two stoke patients with CDs were randomly divided into a CI group and a control group.All patients were treated with conventional CBR.In addition,the patients in the CI group were also treated with special intervention therapy.The patients in both groups were assessed with the neurological and cognitive status examination (NCSE) for cognitive functioning, the FCA for motor function and the BI for their ability in the activities of daily living.Results The NCSE,FCA and BI scores in the cognitive intervention group after treatment were significantly higher than those before treatment and also significantly higher than those in the control group after treatment.Conclusion CIs can not only improve CDs,but also enhance recovery of motor function and ADL.

Objective To investigate the reversal effect of MDR1 and MDR3 gene silencing on resistance of A2780/taxol cells to paclitaxel.Methods shRNA plasmid vector specifically targeting MDR1 and MDR3 genes was transfected into A2780/taxol cells.The early stage cell apoptosis and the effect of intracellular rhodamine 123(Rh123)accumulation were detected by flow cytometry(FCM).The late stage cell apoptosis rate was detected by terminal deoxynucleotidyl transferase(TdT)-mediated deoxyuridine triphosphate(dUTP)nick end labeling(TUNEL).The 50% inhibition concentration(IC_(50))of paclitaxel on A2780/taxol cells was determined by methyl thiazolyl tetrazolium(MTT)assay.MDR1 and MDR3 mRNA were assessed by RT-PCR,and caspase-3 protein was detected by western blot.Results After treatment with MDR1 and MDR3 shRNA plasmid vector,early apoptosis rate of A2780/taxol cells was (20.21?0.56)% and(10.87?1.24)%,respectively.MDR1 and MDR3 shRNA could increase cellular Rh123 accumulation(116.6?8.1 and 98.4?3.8,respectively).The late stage apoptosis rates detected by TUNEL displayed the same tendency as FCM results did.The IC_(50)for paclitaxel of A2780/taxol cells was decreased significantly.The mRNA levels of MDR1 and MDR3 in A2780/taxol cells were decreased by (73.3?0.8)% and(51.6?0.4)% of control,and the reduction of MDR1 and MDR3 mRNA was in a time-dependent manner.The expression of caspase-3 protein of MDR1 and MDR3 shRNA vector transfected group in A2780/taxol cells was significantly increased [(80.8?2.6)% and(72.0?4.7)%, respectively ].Conclusion MDR1 and MDR3 gene silencing could recover sensitivity of A2780/taxol cells to paclitaxel and induce cell apoptosis,thus reversing cell resistance to paclitaxel.
