Objective To compare the diagnostic value of CT and MRI in the diagnosis of far lateral lumbar disc herniation (FLLDH). Methods The CT and MRI imagine data of 34 patients with FLLDH were retrospectively analyzed and compared. Results The positive rate of CT in diagnosis FLLDH was 88.24%(30/34), and the positive rate of MRI was 94.12%(32/34). There was no statistical difference (P>0.05). There were no statistical differences in the diagnosis of disease region and image representation between CT and MRI (P>0.05). Conclusions There is higher coincidence rate of CT and MRI in the diagnosis of FLLDH, but the two imaging methods have their own advantages and disadvantages. In clinical practice, the two imaging methods can be used to improve the clinical diagnosis rate, and provide a reliable basis for determining the surgical treatment options.

Objective To investigate the value of perfusion CT in the evaluation of neoadjuvant chemotherapy in locally advanced squamous cell carcinoma.Methods Sixty-seven patients with Ib2-IIb squamous cell carcinoma of the cervix underwent CT perfusion imaging before neoadjuvant chemotherapy to measure blood flow (BF),blood volume (BV),peak time (MTT),permeability sur-face (PMB),perfusion time to peak (TTP)and MIP(HU);and underwent routine enhancement CT after the two course of neoadju-vant chemotherapy treatment to measure tumor size,and evaluate the therapeutic effect.Results Among 67 patients,48 patents were effective (2 completely remission and 46 partial remission),and 1 9 patients were ineffective (1 5 stable and 4 progressed),with the overall response rate of 71.6%.The differences of PMB and BV value between effective and ineffective group were statistically significant before neoadjuvant chemotherapy (P <0.001).The BF,MTT,TTP value were no significant difference between effec-tive and ineffective group before neoadjuvant chemotherapy (P >0.05).The BV and PMB value were relatively higher in the patients with effective chemotherapy.Conclusion CT perfusion imaging could measure the BV and PMB value of the tumor before neoadju-vant chemotherapy to provide the basis for treatment selection.

OBJECTIVE: To investigate the expression of periostin in in vitro cultured vascular smooth muscle cells (VSMCs) induced by TGF-β1 and the relationship between periostin expression and the migration and proliferation of the VSMCs. Further, to investigate the effects of atorvastatin on the above-mentioned processes and the molecular mechanisms of atorvastatin inhibition of TGF-β1- induced periostin production. METHODS: Rat aorta smooth muscle cells were cultivated by the method of tissue explants adherence. Cells of generation 3 to 6 were used as the experimental system. Primary cultured rat vascular smooth muscle cells were treated by TGF-β1 and different concentrations of atorvastatin,Y-2763 (Rho kinase inhibitor), or atorvastatin plus MVA for 24 hours. The expression of periostin was measured by RT-PCR and Western blot. A Boyden chamber assay was used to measure cell migration, and an MTT test was used to measure cell proliferation. RESULTS: Periostin expression in rat VSMCs stimulated by TGF-β1 increased significantly (4.158 ± 0.515 vs 0.385 ± 0.031), VSMC migration(25 ± 4 vs 8 ± 2) and proliferation (0.85 ± 0.06 vs 0.32 ± 0.03) also increased significantly. Atorvastatin significantly inhibited TGF-β1-induced periostin production in rat VSMCs, as well as VSMC migration and proliferation, in a dose-dependent manner. Rho kinase inhibitor Y-27632 significantly inhibited TGF-β1-induced periostin production in rat VSMCs (2.082 ± 0.245). The inhibitory effect of atorvastatin on periostin upregulation induced by TGF-β1 was reversed by mevalonate (3.838 ± 0.326). CONCLUSION Periostin can promote rat VSMC migration and proliferation. Atorvastatin inhibition of periostin expression induced by TGF-β1 in VSMCs may be exerted by inhibition of the production of MVA and other isoprene compounds and by blocking the Rho/Rho kinase signaling pathway.
