Objective To study the correlation between anatomical measurement and CT measurement of adult occipital thickness so as to provide anatomic evidence for the selection of screw length in occipital-cervical fusion. Methods The occipital thickness was measured on the occipital specimens of 10 normal adults in two ways: direct anatomic measurement and CT measurement. Measurements were made on the basis of the McRac' s line and according to a matrix of 66 points following a grid with one cm spacing. The results of both measurements were statistically analyzed using SPSS 10.0. Results The results of both measurements were highly correlated. The external occipital protuberance was the thickest while the region of cerebellar fossa was the thinnest. The regions two cm lateral to the midline between plane Five and plane Six, one cm lateral to the midline between plane Four and at plane Five, and median between plane Three and plane Four were found to have a thickness of more than eight mm. Conclusions The occipital thickness varies with individuals. CT measurement and direct anatomic measurement are highly correlated. Preoperative CT measurements can be reliable evidence for optimal screw placement before performing occipital-cervical fusions.

Objective:To investigate the expression of miR-203a in bladder cancer (BC) cell lines (RT-112, T24, 5637, UM-UC-3) and evaluate the effects on BC cell proliferation and radiosensitivity.Methods:Mir-203a mimics, mir-203a inhibitor, CDK6 siRNA, CDK6 expression plasmid and corresponding negative controls were transfected into BC cells. Quantitative real-time PCR was used to detect the expression of miR-203a in BC cell lines and human bladder epithelial immortalized cell line (SV-HUC-1). CCK8 assay was used to investigate the regulation of miR-203a and cyclin-dependent kinases 6(CDK6) on the proliferation of BC cells. Colony formation assay was performed to assess the effect of miR-203a and CDK6 on the radiosensitivity of BC cells. The target gene of miR-203a was confirmed by luciferase reporter assay. The effect of miR-203a on CDK6 protein expression was detected by Western blot. Multi-group comparison was performed by one-way ANOVA and two-group comparison was conducted by t-test. Results:Compared with the SV-HUC-1 cells, the expression levels of miR-203a in RT-112, T24, 5637 and UM-UC-3 cells were significantly down-regulated (all P<0.05). Compared with NC group, overexpression of miR-203a significantly inhibited the proliferation of BC cells, whereas knockdown of miR-203a significantly promoted the proliferation of BC cells (both P<0.05). Compared with NC group, overexpression of miR-203a significantly increased the sensitivity of BC cells to radiotherapy, whereas knockdown of miR-203a significantly weakened the sensitivity of BC cells to radiotherapy (both P<0.05). CDK6 was the target of miR-203a. Compared with NC group, overexpression of miR-203a significantly down-regulated the expression level of CDK6 protein, whereas knockdown of miR-203a significantly up-regulated the expression level of CDK6 protein (both P<0.05). After overexpression of CDK6 in T24 and UM-UC-3 cells transfected with miR-203a mimics, the cell proliferation ability was significantly increased, whereas the sensitivity to radiotherapy was significantly decreased compared with mir-203a mimics (both P<0.05). After CDK6 was silenced in RT-112 and 5637 cells transfected with miR-203a inhibitor, the proliferation ability of cells was significantly decreased, whereas the sensitivity to radiotherapy was remarkably increased compared with miR-203a inhibitor group (both P<0.05). Conclusion:miR-203a can serves as a tumor suppressor gene to inhibit the proliferation of BC cells and enhance the radiosensitivity of BC cells.

Objective:To investigate the effects of pulmonary rehabilitation on anxiety/depression and subjective/objective sleep quality of elderly patients with stable chronic obstructive pulmonary disease(COPD).Methods:From February 2018 to February 2019, 120 elderly patients with stable COPD were selected and randomly divided into the experimental group (pulmonary rehabilitation exercise combined with conventional COPD treatment) and the control group (simple COPD conventional treatment). Sixty cases in each group were intervened for 8 weeks. Before and after treatment, Hamilton anxiety scale (HAMA) was used to evaluate anxiety, Hamilton depression scale(HAMD)was used to evaluate depression, Pittsburgh sleep quality index(PSQI)and sleep log were used to evaluate subjective sleep quality, and objective sleep quality was monitored by multi-channel sleep monitor.SPSS 21.0 software was used to analyze and process the data. Chi square test, independent sample t test and paired t test were used for statistical analysis. Results:After 8 weeks of intervention, the HAMA and HAMD scores of the experimental group were lower than those of the control group (HAMA: (7.57±3.19) vs (10.15±4.89), t=-3.428, P=0.001; HAMD: (8.22±4.73) vs (10.60±6.49), t=-2.300, P=0.023). COPD patients with anxiety decreased (χ 2=7.566, P=0.006). After treatment, the subjective sleep latency of the experimental group was shorter than that of the control group ((42.00±9.88)min vs (47.25±10.27)min, t=-2.854, P=0.005). The subjective sleep efficiency was higher than that of the control group ((76.00±4.50)% vs (74.00±5.20)%, t=2.272, P=0.025), and the objective sleep latency was shorter than that of the control group ((28.02±5.59)min vs (32.95±6.21)min, t=-4.575, P<0.05). Conclusion:Pulmonary rehabilitation exercise can improve the anxiety and depression of elderly patients with stable COPD, and improve the subjective and objective sleep quality.
