BACKGROUND:In clinical practice,the anterior superior iliac spine and posterior superior iliac spine are usually located by palpation,and the tilt of the pelvis is determined by visual observation method or photogrammetry.Among them,the visual observation method can only have qualitative conclusions,and its reliability is poor.The photogrammetry is not only more convenient and fast,but also can give more accurate quantitative data,which is one of the best clinical evaluation methods.However,there are no studies on the reliability of pelvic posture assessment using photogrammetry in China. OBJECTIVE:To evaluate the pelvic posture by visual observation method and photogrammetry,and to compare the reliability level of the two methods to guide clinical application. METHODS:Forty-five healthy subjects were selected and red marks were made at the bilateral anterior superior iliac spine and posterior superior iliac spine.Pelvic posture was photographed from the front,back(coronal plane),left,and right(sagittal plane).The left and right pelvic tilt angles(α,β angles)were selected from the front and back views,which represented the angle between the bilateral anterior superior iliac spine line or the bilateral posterior superior iliac spine line and the horizontal line.The anterior and posterior pelvic tilt angles(γ,θ angles)were selected from the side view,which represented the angle between the ipsilateral anterior superior iliac spine and posterior superior iliac spine line and the horizontal plane,indicating the sagittal plane pelvic tilt.Evaluation methods included visual observation method and photogrammetry.Two evaluators independently evaluated the pelvic α,β,γ,θ angles using the visual observation method first,and then recorded the pelvic α,β,γ,θ angles using the photogrammetry.After a one-month interval,the visual observation method and photogrammetry were performed again,and the pelvic α,β,γ,θ angles were recorded.The intraclass correlation coefficients were used to analyze the data obtained from the two evaluation methods and the before-and-after measurements:0.90-0.99 as an excellent correlation,0.80-0.89 as a good correlation,0.70-0.79 as a moderate correlation,and≤0.69 as a poor correlation.The standard error of measurement and the minimal detectable change with 95%confidence intervals were calculated to evaluate the inter-rater and intra-rater reliability. RESULTS AND CONCLUSION:(1)The interrater intraclass correlation coefficients of the visual observation method and photogrammetry were as follows:anterior view:0.682 and 0.718,posterior view:0.513 and 0.867,left view:0.739 and 0.960,and right view:0.756 and 0.971.The visual observation method showed poor correlation between the anterior and posterior views and moderate correlation between the left and right views,while the photogrammetry showed moderate correlation for the anterior view,good correlation for the posterior view,and excellent correlation for the left and right views.The standard error values of measurement were as follows:anterior view:3.266 and 1.625,posterior view:4.278 and 1.763,left view:5.935 and 1.787,and right view:5.723 and 1.698.The minimal detectable change values with 95%confidence intervals were as follows:anterior view:9.053 and 4.504,posterior view:11.858 and 4.887,left view:16.451 and 4.953,and right view:15.863 and 4.707.(2)The interrater intraclass correlation coefficients of the visual observation method and photogrammetry were as follows:anterior view:0.452 and 0.723,posterior view:0.483 and 0.904,left view:0.518 and 0.955,and right view:0.657 and 0.968.The visual observation method showed poor correlation in all four directions,while the photogrammetry showed moderate correlation for the anterior view and excellent correlation for the other three directions.The standard error values of measurement were as follows:anterior view:5.651 and 1.610,posterior view:4.237 and 1.523,left view:7.322 and 1.891,and right view:6.509 and 1.781.The minimal detectable change values with 95%confidence intervals were as follows:anterior view:15.664 and 4.463,posterior view:11.744 and 4.222,left view:20.296 and 5.242,and right view:18.042 and 4.937.(3)These results confirm that the sagittal and coronal plane photogrammetries have good intrarater and interrater reliability for evaluating pelvic posture,especially with the use of the photogrammetry,which has good data stability.This method is simple,fast,efficient,accurate,low-cost,and does not cause X-ray damage,and can qualitatively and quantitatively reflect the actual situation of the patient's pelvis,making it suitable for clinical use.

ObjectiveTo investigate the mechanism by which Shenbai Jiedu prescription (SBJDF) inhibits the proliferation of colorectal cancer (CRC) HCT116 cells. MethodAfter 48 h treatment of HCT116 cells with SBJDF (0, 0.25, 0.5, 1, 2, 4 g·L-1), the viability of HCT116 cells were determined by methyl thiazolyl tetrazolium (MTT) colorimetry. Following the classification of cells into blank control group and SBJDF (1, 2, 4 g·L-1) groups, the effect of SBJDF on HCT116 cell morphology was observed under an inverted microscope. The effects of SBJDF on the proliferation of HCT116 cells and mitochondrial membrane potential (Δψm) were detected by colony formation assay and JC-1 probe, respectively. The flow cytometry was then performed for determining cell cycle distribution and apoptosis. The effects of SBJDF on cell cycle-, apoptosis-, and nuclear factor kappa-B (NF-κB) signaling pathway-related proteins were determined by Western blot. ResultSBJDF effectively inhibited the vitality of HCT116 cells and changed their morphology in a concentration-dependent manner. Compared with the blank control group, SBJDF at 1, 2, 4 g·L-1 significantly reduced cell colony formation (P<0.05, P<0.01),and SBJDF at 2 and 4 g·L-1 arrested the HCT116 cell cycle at G0/G1 phase (P<0.05, P<0.01). Compared with the blank control group, SBJDF at 1, 2, 4 g·L-1 remarkably down-regulated the protein expression of CyclinD1 (P<0.05, P<0.01). SBJDF at 2 and 4 g·L-1 lowered the CyclinA2 and cyclin-dependent kinase 4 (CDK4) (P<0.05, P<0.01). SBJDF at 4 g·L-1 reduced the cyclin-dependent kinase 1 (CDK1) (P<0.01). Compared with the blank control group, SBJDF at 2 and 4 g·L-1 induced HCT116 cell apoptosis, down-regulated the protein expression of anti-apoptosis-related proteins Bcl-2 and Bcl-xl as well as the NF-κB signaling pathway-related proteins IκB kinase α (IKKα),inhibitor α of NF-κB (IκBα),and phospho-NF-κB p65 (p-p65) (P<0.05, P<0.01), and diminished the mitochondrial membrane potential of HCT116 cells. ConclusionSBJDF inhibits the proliferation of HCT116 cells, which may be related to its inhibition of the activation of NF-κB signaling pathway and the induction of cell cycle arrest and apoptosis.
