Objective The evaluate the accuracy of loss of resistance technique for location of fascia iliaca compartment using ultrasound technique.Methods One hundred and seventy-five patients undergoing hip surgery were enrolled in the study.A line was drawn on the skin from the pubic tubercle to the anterior superior iliac spine and divided in three equal parts.The site of puncture was marked 2 cm distal to the point at which the lateral met the middle third of the line.The needle was inserted until a loss of resistance was felt twice (fascia lata and fascia iliaca),at which point 0.5 ％ ropivacaine 30 ml was infused.Correct puncture was identified by visualized spread of local anesthetic solution under the guidance of ultrasound technique.The effective sensory block was recorded within 20 min after administration.Results The accuracy of loss of resistance method for locating the fascia iliac compartment was 56.6 ％ using ultrasound technique.There were 80 patients in whom fault site of puncture occurred:25 cases in the superficial layer of the fascia iliac and 51 cases in the iliopsoas muscle.The rate of effective block was 98.0 ％ for correct location and 82.9 ％ for fault location.Conclusion Loss of resistance technique cannot accurately locate the fascia iliac compartment.

Objective To investigate the expression and clinical significance of myeloid cell leukemia-1 (MCL-1) and F-box and WD repeat domain-containing 7 (FBW7) in breast cancer polyploid induced by spindle poisons. Methods (1) Nocodazole spindle poison was used to treat breast cancer cell MDA-MB-231. The morphological changes of cells were ob?served under microscope, and cells were harvested in 0, 6, 12, 24, 48 and 72 h. The cell cycle and DNA-ploidy changes were examined by flow cytometry. The expressions of FBW7 and MCL-1 proteins were detected by Western blot assay. (2) A multikinase inhibitor (Sorafenib) with Nocodazole or Taxol was used to treat MDA-MB-231 cells. MCL-1 protein expression was detected by Western blot assay after 48 h treatment. The cell cycle and DNA-ploidy changes were examined by flow cy?tometry after 48 h treatment. MTT method was used to observe cell proliferation after 48 and 72 h treatment. Results (1)Af?ter treatment by Nocodazole, polyploid characteristics of large cell size and nucleus were appeared. The percentages of octa?ploid were (0.8±0.2)%, (8.5±2.3)%, (7.8±2.0)%, (9.9±0.9)%, (28.2±0.8)%and (35.1±4.9)%after 0, 6, 12, 24, 48 and 72 h treatment, showing the increasing trend in turn (P<0.001). The number of polyploidy (tetraploid and octaploid) cells was as high as (97.6±0.7)%after 48 h treatment. The expression level of FBW7 protein was decreased significantly but the expres?sion of MCL-1 protein was increased significantly after 48 h treatment. (2) After 48 h treatment, the expression level of MCL-1 protein, polyploidy percentage and cell proliferation decreased significantly in Nocodazole+Sorafenib group and Taxol+Sorafenib group compared with those of Nocodazole group and Taxol group (P<0.05). Conclusion The lower expression of FBW7 protein and over-expression of MCL-1 protein are correlated with the formation of breast cancer polyploidy. Sorafenib can reduce polyploid tumor cells by inhibiting MCL-1 protein expression.

OBJECTIVETo observe the localization of p53(301-393)(residues 301-393) in p53 positive/negative cells and its effect on cell mitosis.

METHODSThe protein expression of p53-GFP and p53(301-393)-GFP was checked by immunoblotting after transfection. Immunofluorescence staining was performed to detect the localization of wide type and mutant in Hela cells (p53 positive) and H1299 cells (p53 negative). The cell morphology of H1299 cells transfected of p53(301-393)-GFP and the cells in mitotic phase were observed. Cell cycle was analyzed by flow cytometry and p53 protein level in HeLa cells was evaluated by Western blot after transfection of p53-GFP and p53(301-393)-GFP.

RESULTSThe protein expression of p53-GFP and p53(301-393)-GFP was verified, p53-GFP was about 90 kMr and p53(301-393)-GFP about 40 kMr. Immunofluorescence microscopy demonstrated that both proteins were diffusely located in the nuclei of HeLa cells and H1299 cells. But different from the p53-GFP, the p53(301-393)-GFP was distributed in the nucleolus of HeLa cells. After transfection of the two plasmids, mitosis was inhibited in H1299 cells and some cells underwent apoptosis. G2/M progression of HeLa cells could be blocked by transfection of p53(301-393)-GFP, but endogenous p53 protein level was not changed.

CONCLUSIONp53(301-393)has a different localization in the p53 positive and p53 negative cells and could inhibit mitosis and cause the cell cycle arrest in G2/M.
