Mitogen activated protein kinase(MAPK) is one of the four biggest signal transduction systems which contain four subtribes named p38,ERK5/BMK1,ERK and JNK/SAPKrespectively.Previous studies have shown that MAPK pathway is involved in growth,cell differentiation,perishing,the synchronization of cell function and so on.p38MAPK,one of the members of MAPK family,plays an important role in the activation of inflammation-related cells to release inflammation mediator,modulating enzyme production as well as transferring factors activity in the process of chronic bronchitis(CB).This review focuses on multiple roles of p38MAPK in the pathogenesis and progression of CB.

Aim To investigate the effect of TAL and MAPK signal transduction on alveolar macrophage (AM) apoptosis and activity of chronic bronchitis (CB) rats.Methods CB model was established by BCG+LPS method and the in vitro and in vivo experiments were used. MTT method was used to detect the AM activity,and the apoptosis of AM was observed by electron microscope.Results The number of AM in BALF of CB rats was increased than that of normal group (P<0.01).The activity of AM was increased in model group than in control group.The apoptotic rate of AM in CB group was much lower than that in the control group [(13.93±3.34)% vs (5.37±1.38)%] (P<0.01).ERK inhibitor PD98059 induced the apoptosis of cultured AM while JNK inhibitor Curcumin reduced the apoptosis.TAL could inhibit ERK MAPK phosphorylation in AM of CB rats.Further investigation showed that Bcl-2 protein expression was significantly increased while Bax evidently decreased in AM of CB rats.TAL could significantly decrease Bcl-2 expression and increase Bax protein expression, which might be the mechanism of its effect.Conclusions There is an increased activity and decreased apoptosis of AM in CB rats compared with normal rats. TAL can inhibit AM activity and increase apoptosis of AM in CB rats which may be related to the therapeutic effect of CB. ERK and JNK MAPK signal transduction participates in the apoptosis of AM. Regulation of Bcl-2/Bax imbalance and MAPK phosphorylation in AM of CB rats might be the mechanism of its effect.

Background Rare studies on the effect of statin on early stage of atherosclerosis have been repor- ted.Oxidative stress induced endothelial dysfunction may be the initiative factor for the development of atheroscle- rotic plague.Objective To investigate the mechanisms by which simvastatin,prevents atheroselerosis independ- ently of its lipid-lowering effect in Apolipoprotein E deficient mice.Methods Twenty-four 6 week old male apoE- deficient mice were randomly to receive placebo or simvastatin 5 mg/(kg?d)by gavage for 4 weeks.Total choles- terol(TC),super oxide dismutase(SOD),malondialdehyde(MDA)and serum nitric oxide(NO)were measured by biochemical analysis.Endothelium was observed by HE dyeing.The expression of caveolin-1 in aortic wall was detected by immunohistochemistry.Results There was no significant difference in serum TC between control and simvastatin treatment groups.Simvastatin caused less damaged endothelium(33.33% vs control's:75%,P

Objective:To construct a recombinant adenovirus containing cytosine deaminase( CD ) gene and thymidine kinase( TK ) fusion gene for the gene therapy research of malignant tumors. Methods: A recombinant cosmid containing CD and TK fusion gene was constructed, and then mixed with DNA TPC and co transfected to the 293 cells by calcium phosphate coprecipitation. Results: The results of restriction and PCR showed the insertion was right and the recombinant adenovirus generated contained the CD and TK fusion gene without replication competent adenovirus. Conclusion: The recombinant adenovirus generated is E1 and E3 deleted and contains double suicide gene needed, which can be further studied for gene therapy.

Objective To observe the surgical results of prominent malar-complex and to explore the more effective methods by improving the shape of face through operation.Methods Total 80 patients of prominent malar-complex were treated by strengthening reduction plasty of mala and zygoma through intra-oral approach accompanied with minor pre-auricular incision and the midfacial SMAS lift in order to improve the shape of prominent malar-complex and to prevent malar-cheek parenchyma sag.Results The face skeleton and midfacial chalasis of all patients were significantly improved with satisfaction.All the patients obtained good results during the follow-up period of over six months.Of them there was one case of maxillary sinusitis that had been cured by further symptomatic treatment.Conclusions Strengthening reduction plasty of mala and zygoma accompanied with the midfacialSMAS lift can properly and safely improve the facial shape of patients with prominent malar-complex.

Objective To evaluate the indications,techniques and effects of high speed drill assisted cervical pedicle screw-rod system in treatment of cervical interlocking dislocation.Methods A retrospective review was made on data of 13 cases of cervical interlocking dislocation undergone pedicle screw-rod fixation and reduction with assistance of high speed drills from December 2006 to July 2011.Dislocation localized in C3/4 (n =3),C4/5 (n =5),C5/6 (n =4) and C6/7 (n =1) respectively.Causes for injury contained cervical hyperextension due to traffic accidents (n =7) and a fall from the height (n =6).Two remained neurological intact,seven were combined with syndrome of central canal damage,and four had paraplegia.All the 13 cases received posterior pedicle screw fixation and reduction within 7 days after injury.Pedicle screws were implanted on adjacent segment of cervical spine with unlocking the interlocked small joints by a distraction device.Results All 13 cases obtained good reduction,including eight with complete anatomic reduction and five with 1-2 mm of vertebral slight slippage.Fifty-two screws were inserted and 49 pedicle screws were put in place except for the excursion in three pedicle screws on the postoperative radiographic and CT scans.There was no injury of spinal cord,nerve root or vertebral artery during operation.The patients showed significant improvement in sensory and motor function of the upper extremities in the follow-up of 12-36 months.One case had screw breakage at postoperative three months with no nerve symptoms.Conclusion High speed drill assisted pedicle screw-rod system is suitable for treatment of cervical interlocking dislocation,for its reduction process accords with the biomechanics and allows decompression therapy.
