RESUMO
Objective:To systematically evaluate the effect of physical exercises on the treatment of constipation by Meta-analysis.Methods:Randomized controlled trials of the effects of physical exercises on constipation were retrieved in databases of CNKI, WanFangData, VIP, SinoMed, PubMed, Web of Science and Cochrane Library from inception to December 2020. According to the inclusion and exclusion criteria, two reviewers independently selected literature, extracted data. The quality of included literature was evaluated by referring to the Cochrane collaboration's tool. And then the funnel plot was used to evaluate the risk of bias of included literature. Revman 5.3 software was used to conduct meta-analysis.Results:A total of 12 clinical trials include 1 004 patients were involved based on the inclusion and exclusion criteria. The physical exercise group was subjected to physical exercise or added other conventional treatment, and the control group had no regular exercise or only conventional treatment during the test. The fixed effects model was employed. The total effect of the value of the merger was calculated, the combined OR(95% CI) was 4.75(3.47, 6.51). Compared with the control group, exercise significantly relieved the patient's constipation symptoms( Z=9.69, P<0.000 01). Funnel figure shows a basic symmetry, which indicated the publication bias is small. Conclusions:Physical exercise is beneficial to constipation should be encouraged.
RESUMO
Objective To explore the infection status of high risk human papilloma virus (hrHPV) and its effects and clinical significance on expression of cysteinyl aspartate specific protease 1 (Caspase-1) and interleukin 1 β(IL-1β)in tissues of human cervical carcinoma. Methods A total of 102 patients with cervical carcinoma (cervical carcinoma group), 60 patients with cervical intraepithelial neoplasia (CIN group) and 30 patients with normal cervix (control group) were used as the research objects. PCR reverse dot hybridization method combined with DNA chip technique were used to detect hrHPV. The expressions of Caspase-1 and IL-1β were detected by immunohistochemical technique. Data were analyzed between hrHPV positive group and hrHPV negative group, between single type of hrHPV infection group and multiple type of hrHPV infection group. The relationship between caspase-1 and IL-1βexpression and clinicopathological parameters in cervical carcinoma patients were observed. Results HrHPV infection was detected in 75 cases(73.5%)in cervical carcinoma group and 11 types of hrHPV were detected. In these 11 cases, single type and multiple type of hrHPV infection were 61 cases(81.3%)and 14 cases(18.7%) separately. HrHPV infection rate was much higher in cervical carcinoma group than those in CIN group and control group(36.7%and 6.7%). Caspase-1 and IL-1βpositive rates were significantly higher in cervical carcinoma group(61.8%and 51.0%)than those in control group(26.7%and 23.3%). The positive rate of Caspase-1 was significantly higher in cervical carcinoma group than that in CIN group(40.0%, all P0.05). The difference of positive expressions of Caspase-1 and IL-1βwere significantly related with cell differentiation, tumor size, lymphatic metastasis and clinical stage(P<0.05 or P<0.01). Conclusion There are single and multiple types of hrHPV infection in cervical carcinoma and the infection rate is high. HrHPVs may promote the progression of cervical carcinoma by restraining the expressions of Caspase-1 and IL-1β.
RESUMO
typeⅢgold alloy. Candida albicans could be found on acrylic resin ,but there was little on the other 4 dental metals. Conclusion: From the perspective of reserving periodontal tissue, pure-Ti and typeⅢgold alloy seem to be the first choice, Co-Cr alloy and Ni-Cr alloy are the second.
