RESUMO

Osteoarthritis (OA) has been scarcely researched among patients with diabetes mellitus. This study aims to confirm the preventive and therapeutic effects of undenatured type II collagen (UC II) on OA in aging db/db mice and in patients with T2DM. Firstly, aging db/db mice were randomly assigned to three groups: the UC II intervention (UC II) group, old model (OM) group and positive control group. Meanwhile db/m mice and young db/db mice were used as the normal control and young control groups, respectively. Secondly, fifty-five T2DM patients diagnosed with knee OA were randomly assigned to two groups: UC-II and placebo control groups. After a three-month intervention in both mice and T2DM patients, the subjects' gait and physical activities were assessed and the serum biomarkers including inflammatory cytokines, oxidative stress factors and matrix metalloproteinases (MMPs) were measured. Compared with the OM group mice, those in the UC II group showed a significantly greater superiority in terms of motor functions including the movement trajectories area (163.25 ± 20.3 vs. 78.52 ± 20.14 cm2), the tremor index (0.42 vs. 1.23), standing time (left hind: 0.089 ± 0.03 vs. 0.136 ± 0.04 s), swing (right front: 0.12 ± 0.02 vs. 0.216 ± 0.02 s), stride length (right hind: 7.2 ± 0.9 vs. 5.7 ± 1.1 cm), step cycle (right hind: 0.252 ± 0.05 vs. 0.478 ± 0.11 s) and cadence (14.12 ± 2.7 vs. 7.35 ± 4.4 steps per s). In addition, the levels of IL-4, IL-10, CTX- II and TGF-ß in the UC II group were 1.74, 2.23, 1.67 and 1.84 times higher than those in the OM group, respectively, while the levels of MMP-3 and MMP-13 in the UC II group were half those in the OM group. Correspondingly, UC II intervention significantly decreased the scores of pain, stiffness and physical function (p < 0.05), whereas the 6 MWT and total MET distances in the UC II group increased remarkably (p < 0.05). After a three-month period of intervention, the varus angle significantly decreased from 4.6 ± 2.0° to 3.0 ± 1.4° and the knee flexion range obviously increased from 57.9 ± 14.0° to 66.9 ± 10.4°. Importantly, the declining trend in the levels of hs-CRP and MDA and the incremental trend in the SOD level were consistent in the db/db mice and OA patients following UC II administration.

RESUMO

Objective To investigate the expression and clinical significance of mammalian sterile 20-like kinase 1 (MST1) in cervical cancer. Methods Immunohistochemical method was applied to detect the expression level of MST1 protein in specimens of cervical cancer tissues (n=139) and pericarcinomatous tissues (n=20, with≥4 cm distance from the primary tumor's edge). Western blot assay and qPCR were used to detect the protein and mRNA transcription expression levels of MST1 in 20 pairs of cervical cancer tissues and pericarcinomatous tissues, respectively. The correlation between MST1 expression, clinic pathological features and the prognosis were analyzed. Results MST1 was mainly expressed in cytoplasm. The positive expression rate of MST1 was significantly lower in cervical cancer tissues (27%, 38/139) than that in pericarcinomatous tissues (80%, 16/20,χ2=21.62, P<0.01). The expressions levels of MST1 protein and mRNA were both lower in the cervical cancer tissues (P<0.01). In cervical cancer, the positive expression rate of MST1 inⅠb+Ⅱa stage was higher than that ofⅡb+Ⅳstage (P<0.05), the positive expression rate of MST1 in lymph node metastasis was lower than that of without lymph node metastasis (P < 0.05). Values of age, tumor size, histological type and differentiation degree showed no significant difference to positive expression rate of MST1. Moreover, the negative expression of MST1 displayed a significantly poorer overall survival time than that of positive expression of MST1 (Log-rank χ2=28.35, P < 0.01). Conclusion MST1 shows a lower expression in cervical cancer, which may be a new target for clinical treatment and prognosis of cervical cancer.

RESUMO

Objective To discuss the effect of MST1 (mammalian sterile 20-like kinase 1,MST1) on the prolifera-tion,migration and invasion of SiHa cervical cancer .Methods Western blot was used to detect the expression of MST1 in cervical epithelial cells H8 and cervical cancer cells SiHa;PJ3H-HA-MST1 was constructed and transfect-ed it to SiHa cells by Lipofectamine TM3000;MST1, Ki-67 and MMP9 protein expression were evaluated by Western blot;While the proliferation ,migration and invasion of SiHa cell were assessed by MTS ,scratch adhesion test and Transwell assay respectively .Results Compared SiHa cells with H 8 cells,MST1 expression in SiHa cells was sig-nificantly lower than that in H8 cells.The plasmid was successfully transfected into SiHa cells , MST1 expression was significantly higher , while the expression of Ki-67 and MMP9 was lower .The proliferation , migration and inva-sion ability were all significantly suppressed .Conclusions Overexpression of MST1 can inhibit the proliferation , migration and invasion of cervical cancer cell line SiHa .

RESUMO

OBJECTIVE:To investigate the clinical efficacy and safety of Recombinant human interferon α2b(rhIFN α2b) vaginal effervescent capsules combined with radiofrequency ablation in the treatment of cervical erosion with human papilloma virus (HPV)subclinical infection(SPI). METHODS:A total of 207 cervical erosion patients with SPI were selected from gynecology outpatient department of our hospital during Jul. 2014-Aug. 2015 and then divided into group A,B,C according to random number table,with 69 cases in each group. Group A was given rhIFN α2b vaginal effervescent capsules 800 thousand IU,via posterior for-nix,qd,3 days after the end of menstruation,10 days as a treatment course,for 3 courses. Group B received radiofrequency abla-tion. Group C was given constant dose of rhIFN α2b vaginal effervescent capsules combined with radiofrequency ablation. The clini-cal efficacy of 3 groups,the rate of wound healing,the rate of associated symptoms disappearance 2 weeks after surgery and the in-cidence of complications in group B and C were evaluated. The occurrence of ADR was recorded. RESULTS:The response rates of group B,C were 94.20% and 98.55%,which were significantly higher than 62.32% of group A. The response rates of SPI in group C was 92.75%,which was significantly higher than 63.77% of group B,with statistical significance(P0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:rhIFN α2b vaginal effervescent capsules combined with radiofrequency ablation can effective-ly improve the efficacy of cervical erosion with SPI,shorten the wound healing time with good safety.

RESUMO

Objective To investigate the clinical prediction value of chemokine CCL21 level for acute coronary syndrome.Methods Totally 212 patients receiving coronary arteriography were divided into acute myocardial infarction group(AMI,n=72),unstable angina pectoris group(UAP,n=76),and stable angina pectoris group(SAP,n=64).The serum level of chemokine CCL21 was detected by double-antibody sandwich enzyme-linked immunosorbent assay (ELISA)and the pathological changes of coronary artery were measured by Gensini scoring system.All patients were followed up for six months and the cardiovascular adverse events were recorded.Results The serum level of CCL21 was(169.72±14.64)ng/L in AMI group,(154.42±16.50)ng/L in UAP group,and(143.87±9.80) ng/L in SAP group,with statistically significant differences (F =99.818,P =0.000).Serum levels of CCL21 in ACS group and SAP group were positively correlated with Gensini score(r=0.474,P =0.000;r=0.350,P=0.049).Binary Logistic regression analysis revealed that chemokine CCL21 was an independent risk factor for predicting acute coronary syndrome (OR =1.049,P =0.022).The CCL21-judged area under the ROC curve in acute coronary syndrome group was 0.887 ± 0.028 (P =0.000),with diagnostic point of serum level of chemokine CCL21 at 159.15 ng/L,sensitivity of 0.635,specificity of 0.981.Serum level of CCL21 was higher in the patients with cardiovascular adverse events than in the patients without cardiovascular adverse events[(168.57±7.24)ng/L vs.(156.92± 6.53) ng/L],with statistically significant difference (t =16.100,P =0.000).Conclusions Serum level of chemokine CCL21 reflects the severity degree of coronary artery disease.The chemokine CCL21,as an independent and effective marker,can predict acute coronary syndrome.
