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.

Objective:To test Jiang Guangrong's(2005)three-dimension model on the depth of counseling process.Methods:In this process-outcome research,28 sessions in a university counseling center were videotaped and coded in terms of the model.Structure Equation Model(SEM)was used to examine the relations between the coding and counselors and clients' evaluation of the session depth.Results:(1)Clients and counselors evaluated differently on the session depth,and clients' evaluation was more positive than counselors' [(4.95±1.12)vs.(4.23±0.94),P<0.05];(2)The model was significantly correlated with counselors' session depth evaluation(path coefficient = 0.55,P<0.01),but not with the clients';(3)The session curves describing each dimension changing over time had different patterns in sessions of different depth level,through which more about the counseling process could be known.Conclusion:The three-dimension model on the depth of counseling process has got some empirical evidences.

Objective To evaluate the association between genetic polymorphisms in promoter regions of matrix metalloprotein‐ase‐1 (MMP‐1)‐1607bp1G/2G ,matrix metalloproteinase‐7 (MM P‐7)‐181‐bpA /G and susceptibility of cervical cancer using Meta‐analysis .Methods Relevant studies that had relationships of the polymorphism in promoter regions of matrix metalloproteinase‐1 (MM P‐1)‐1607bp1G/2G ,matrix metalloproteinase‐7 (MMP‐7)‐181‐bpA /G and susceptibility of cervical cancer were collected as case‐control groups .RevMan5 .0 software was applied to analyze the odds ratios (OR) and 95% confidence intervals(CI) of the as‐sociation between polymorphisms and susceptibility of cervical cancer .Results Finally ,6 studies were selected ,containing 4 studies of MMP‐1 and 2 studies of MMP‐7 .For MMP‐1‐1607bp1G/2G ,OR was 0 .76 (95% CI = 0 .51 - 1 .13 ,P= 0 .17) under 1G/1G +1G/2G ∶ 2G/2G model ,OR was 0 .72 (95% CI = 0 .42 - 1 .23 ,P = 0 .42) under 1G/1G ∶ 2G/2G model ,OR was 0 .79(95% CI =0 .57 - 1 .09 ,P= 0 .15) under 1G ∶ 2G model ,it was concluded that there was no statistical significance between them .For MM P‐7‐181bpA /G ,OR was 0 .47 (95% CI = 0 .30 - 0 .74 ,P= 0 .001) under AA + AG ∶ GG model ,OR was 0 .43 (95% CI = 0 .26 - 0 .74 , P= 0 .002) under AA ∶ GG model ,OR was 0 .77(95% CI = 0 .62 - 0 .94 ,P= 0 .02) under A ∶ G model ,there were statistical signifi‐cance differences under all models .Conclusion Polymorphisms in promoter of MMP‐7‐118bpA/G are associated with the suscepti‐bility of cervical cancer and an allele is a protective factor .It is still not confirmed that significant association between the MM P‐1‐1607bp1G/2G and susceptibility to cervical cancer exists in current literature .

Objective To investigate the application value of detection of serum miRNA-210,miRNA-23b in the patients with the femoral head necrosis.Methods The serum and clinical data of 135 patients with the internal fixation operation for the femoral neck fracture were collected.The patients were divided into the necrosis group (27 cases) and non-necrosis group (108 cases),used the real-time fluorescent quantitative PCR (Real time-PCR,RT-PCR) technology to detect serum miRNA-210,miRNA-23b expression in comparatively analysizing the relationship between the changes of serum miRNA 210,23b and occurrence of the femoral head necrosis.Results The serum microRNA-210,-23b expression in the necrosis group were 0.19±0.03,0.21±0.05,which in the non-necrosis group were 0.92±0.18 and 0.87±0.17.The serum microRNA-210,-23b expression in the necrosis group were significantly lower than those in the non-necrosis group,the difference had statistical significance (P＜0.01).The analysis results from the receiver-operating characteristic curve (ROC curve) showed that AUC of serum miRNA-210,miRNA-23b expression were 0.790 (95％CI:0.687～0.892,P=0.000) and 0.743 (95％CI:0.633～0.854,P=0.000),respectively.The sensitivity and specificity of miRNA-210 and miRNA-23b at the best threshold in diagnosis of the femoral head necrosis were 95.7％ and 93.9％,91.5％ and 92.3％,respectively.The analysis results showed that the serum miRNA-210,-23b expression had clinical significance in diagnosis of the femoral head necrosis.Conclusion Detection of serum miRNA-210,-23b expression can predict occurrence of the femoral head necrosis,estimate development condition of the desease.

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.
