Objective:To investigate the expression and significance of NF-?B,and ICAM-1 in laryngeal carcinoma patients.Methods:Two groups of laryngeal carcinoma tissue (one group derived from the laryngeal carcinoma patients;the other from the normal persons) were detected for NF-kappa B P65 protein and ICAM-1′s expressions by immunohistochemistry staining.Results:(1)The expressions of NF-kappa B P65 protein and ICAM-1 of the laryngeal carcinoma patients were much more strengthened than those of the normal persons(P

Objective:To explore the expression and significance of IKK, I?B and NF-?B P65 of NF-? B signal transduction pathway in laryngeal carcinoma patients.Methods:The expression of IKK?, I?B?,NF-?B P65 was examined by immunohistochemical S-P method in laryngeal carcinoma tissues of 40 cases and normal laryngeal tissues of 20 cases.Results:The expression of IKK? and NF-?B P65 in laryngeal carcinoma tissue was higher compared with normal laryngeal tissue,while the expression of I?B? was lower( P

Objective:To investigate the effects of siRNA-mediated Plk1 depletion on COS-7 cells and the therapeutic potential of Plk1 in cancer treatment.Methods:Small interfering RNA(siRNA) were used to specifically deplete Plk1 in COS-7 cells.RT-PCR and immol/Lunoblotting analysis were used to verify the inhibitory effect of siRNA against Plk1.Trypan blue exclusion assay and FACS analysis were conducted to determine the effects of Plk1 depletion on the growth and cell cycle profile of COS-7 cells.Results:Synthetic siRNA duplexes against Plk1 were introduced into COS-7 cells,which subsequently resulted in a significant inhibition in Plk1 expression in the cells.Cell growth assay indicated that siRNA-mediated Plk1 depletion significantly inhibited the proliferation of COS-7 cells.FACS analysis revealed that Plk1 depletion caused cell cycle arrest,resulting into large population of sub-G1 cells.Conclusion:siRNA-mediated Plk1 depletion significantly inhibited the proliferation of COS-7 cells suggesting the therapeutic potential of Plk1 in cancer treatment.

Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia,which is rare in children.The treatment of APL mainly includes anthracycline-based chemotherapy,all-trans retinoic acid,and arsenic trioxide,which allow for complete remission,improve the long time survival rate and reduce related toxicity as well.About the optimized treatment,quick breakthroughs have already reached,not only at home in the 80's at the end of the 90's,but also abroad,like National Comprehensive Cancer Network of the United States in 2006-2013.This review summarizes the progress in diagnosis and treatment of children with APL.

Objective To evaluate the clinical application value of percutaneous lung biopsy by CT fluoroscopy.Methods we analysed 31 cases of percutaneous lung biopsy by CT fluoroscopy which were proved by operation or pathology,with the puncture needle produced by Cook Co..The main point are: choose the best layer,point,angle,depth,draw and obtaining at many points.Results In these 31 cases,accurate diagnosis is 29 cases,include 9 cases of adenocarcinoma,6 cases of SqCa,2 cases of small cell carcinoma,1 case of metastatic carcinoma,1 case of alveolar cell carcinoma,5 cases of TB,4 cases of infection,1 case of inflammatory pseudotumor.The diagnosis accurate rate is 93.5%.2 cases were not diagnosed accurately,2cases of pneumothoras,complication rate is 6.5%.Conclusion The percutaneous lung biopsy by CT fluoroscopy was high diagnosis accurate rate,less of complication,this is a safe,effective,simple and practical way for diagnosing lung diseases.

Objective:To observe the effects of endocrine mechanism on uterine contraction on late pregnancy rats by applying acupuncture on KI6 using"open-close"needling time and"host-guest"needling sequence according to eight methods of the intelligent turtle.Methods:32 pregnant rats were divided into"open/host-guest"group(OHG group),"open/guest-host" group(OGH group),"close/host-guest"group(CHG group)and pregnant control group(PC group).8 healthy grown-up female rats were made into un-pregnant control group(UPC group).Firstly,open KI6 time was calculated.OHG group and OGH group were needled during the KI6 open time but CHG group was needled during the KI6 close time.Host-acupoint KI6 and guest-acupoint LU7 were needled for 5 minutes separately.After this,LI4 was needled for 20 minutes and then SP6 for 5 minutes.The contents of serum Estradiol(E2),Progesterone(P),ThromboxanceB 2(TXB 2)and 6-Keton-ProstaglandinF 1?(6-K-PGF 1?)were measured. Results:Compared with UPC group,the contents of serum P in OHG group increased significantly(P

Bone marrow mesenchymal stem cells(MSCs) are a sort of somatic stem cells deriving from the mesoderm.They are capable of self-renewing,differentiating into mesenchymal or non-mesenchymal tissues,anti-inflammatory,reducing oxidative stress and immunomodulatory.MSCs exert their protective effect on various tissues,especially the ischemia-reperfusion injured tissue.This review summarizes the repairative potential of MSCs on ischemia-reperfusion injury.

Objective:To make a synthetic comment on treatment of children cerebral palsy with acupuncture in recent 10 years in China.Methods:Related papers were gotten from the journals between 1999-2008 in Chinese journal full-test database and VIP information-Chinese technology journal database by computer retrieval.The collected 143 papers were analyzed from the terms of clinical acupoints selection,treatment methods,time,and mechanism,and then summarized the clinical effects of acupuncture in treating children cerebral palsy.Results:The acupoints selection was focus on scalp acupuncture functional area and body points(including scalp points).Beside acupuncture treatment,the combination of acupoint embedding therapy,acupoint injection,and massage were also used.The therapy time was different from 20min to 4h,and the treatment course was usually be counted by month.The effects of acupuncture treatment were considered to be significant through improving brain circulation and recovering brain cells' function. Conclusion:Acupuncture treatment had advantages in improving the child'limbs function,nevertheless further studies on the research methods,study design and mechanism were all needed.

Calcific aortic valve disease(CAVD) is the most common valvular disorder.There is no medical treatment to prevent and/or reverse the progression of CAVD and the etiology still requires further study.CAVD has long been described as a degenerative disease related to aging.In the past few years,our comprehension of the etiology and mechanisms leading to CAVD has progressed at a fast pace.In this article,we review the latest discoveries of CAVD,from aspects of lipid retention,inflammation,calcification,osteogenic transition and their basic molecular processes.

Objective To compare the mortality,valve-related morbidity and reoperation rate between mechanical prostheses and bioprostheses in patients aged 60 to 70 years.Methods The pre-operative characteristics of 119 patients who received mechanical prostheses and 181 those with bioprosthesis implantation in our department between January 2006 and December 2014 were analyzed,and their mortality,valve-related morbidity and reoperation rate were compared.Results Followup revealed mechanical prostheses had a lower all-cause mortality after mitral valve replacement than bioprostheses at 6 years after the operation (P=0.033),but there was no statistical difference in valve-related mortality (P=0.277).The complications after mechanical prosthesis replacement had embolism (8.4％) and bleeding (5.0％),bioprosthesis' those consisted of structural valvular deterioration (2.2％),nonstructural dysfunction (1.1％),thrombosis (2.8％),embolism (5.0％),bleeding (0.6％) and operated valvular endocarditis (1.1％).There was no statistically significant difference in total complication rate between the two groups (P=0.318).Biological group had 3 patients receiving reoperation in 8 years,while there was no reoperation in the mechanical group,but without statistical group difference.Conclusion Patients aged 60-70 years old could have a similar valve-related mortality,morbidity and reoperation rate after mitral valve replacement between mechanical and biological valves.
