Objective: To investigate the expression of voltage-dependent potassium channel 1.3(Kv1.3) mRNA and protein during human monocyte-derived macrophage differentiation into foam cells and its function in foam cell formation. Methods: Human peripheral blood monocytes were isolated from healthy male volunteers by density gradient centrifugation and then by adherent method. The obtained monocytes were cultured for 5 days to differentiate into macrophages. Based on establishment of the human macrophage-derived foam cell model, the expression of Kv1.3 channel was investigated by immunocytochemical staining, reverse transcription-polymerase chain raction (RT-PCR) and Western blot. Furthermore, the effects of rMargatoxin, a Kv 1.3 channel-specific inhibitor, on cholesterol metabolism in macrophages incepting oxidized low density lipoprotein (OxLDL) were studied. Results: After the macrophages co-incubated with 30 mg/L OxLDL at 37 ℃ for 60 hours, the cellular volume obviously enlarged and many red lipid granules were deposited in cytoplasm. The total amount of cholesterol (TC),free cholesterol ( FC ) and cholesterol ester ( CE ) in cells markedly increased and the ratio of CE/TC rose from ( 14.4±6.8) % to (57.9±3.5) % (n=7,P＜0.05). However, the expression of Kv1.3 channel had no significant change. r Margatoxin (0.1 nmol/L and 10 nmol/L) markedly reduced the contents of TC, FC and CE in macrophages and the ratios of CE/TC decreased to (42.8±11.6) % and (22.6±8.0)% , respectively (n=7, P＜0.05). Meanwhile, the red lipid granules deposited in the cytoplasm of macrophages also decreased. Conclusion: These data clearly show that the expression of Ky1.3 channel does not change obviously during human monocyte-derived macrophage differentiation into foam cells and the blocking of it would prevent foam cell formation.

Objective To approach the evaluative effect of respiratory variation of superior vena cava peak flow velocity measured using transthoracic echocardiography (TTE) on fluid responsiveness in patients with mechanical ventilation.Methods A prospective cohort study was conducted.All mechanical ventilated critically ill patients whose fluid therapy was planned due to hypovolemia in Department of Critical Care Medicine of Beijing Tongren Hospital of Capital Medical University from April 2011 to April 2013 were enrolled.Volume expansion was performed with 500 mL Linger solution within 30 minutes.Patients were classified as responders if pulse pressure variation (PPV) increased ≥ 13％ before volume expansion.The respiratory variation in superior vena cava peak velocity was calculated as the difference between maximum and minimum values of velocity in peak A,peak S and peak D over a single respiratory circle,and their variations (ΔA,ΔS,ΔD) were also calculated.The receiver operating characteristic curve (ROC curve) was plotted to assess the evaluative effect of respiratory variation of superior vena cava peak velocity on fluid responsiveness.Results Twenty-seven patients were enrolled in this study.Volume expansion increased PPV ≥ 13％ happened in 14 patients (responders).The velocity of superior vena cava in peak A,peak S,peak D was significantly increased after volume expansion compared with that before volume expansion in responders [peak A (cm/s):34.6 ± 2.2 vs.31.3 ±2.1,t=-2.493,P=0.027; peak S (cm/s):39.1 ± 1.3 vs.35.3 ±2.1,t=-2.564,P=0.024; peak D (cm/s):28.1 ± 1.2 vs.23.3 ± 1.4,t=-4.995,P=0.000],but there was no significant difference in ΔA,ΔS and ΔD between before and after volume expansion.The ΔA,ΔS and ΔD were positively correlated with PPV (r＝0.040,P=0.854; r=0.350,P=0.074; r=0.749,P=0.000).The area under ROC curve (AUC) of peak S was 0.36 [95％ confidence interval (95％CI):0.11-0.52],but the AUC of ΔS was 0.68 (95％CI 0.47-0.89),the AUC of peak D was 0.41 (95％CI 0.19-0.63),but the AUC of ΔD was 0.95 (95％CI 0.86-1.00),so the aberration rate of superior vena cava in respiration was better than the flow rate in superior vena cava.When the cut-off value of ΔS was 20.7％ for predicting fluid responsiveness,the sensitivity was 78.6％ and the specificity was 61.5％.When the cut-off value of ΔD was 12.7％ for predicting fluid responsiveness,the sensitivity was 92.0％ and the specificity was 92.3％.Conclusion Respiratory variations in superior vena cava peak velocity measured by TTE could assess fluid responsiveness in patients with mechanical ventilation.

Objective To investigate the correlation between retraction phenomenon on the coronal planes obtained by an automated breast volume scanner ABVS and biological behaviors of breast cancer Methods Two hundred and eighty-eight female patients with 293 pathologically proven breast cancers were included in this study All of them underwent ABVS examinations before surgery Retraction phenomenon on the coronal planes was evaluated retrospectively Correlation between retraction phenomenon and hormone receptor HR human epidermal growth factor receptor 2 HER-2 Ki-67 molecular subtypes histologic type histologic grade lymph node status lesion size and patient age were evaluated by univariate logistic regression analysis Above significant variables were then enrolled in multivariate logistic regression analysis to select independent risk factors for retraction phenomenon Results By univariate logistic regression analysis Luminal A subtype odds radio OR =8 395 P <0 001 HR positive OR=4 876 P <0 001 HER-2 negative OR = 4 407 P < 0 001 lower expression of Ki-67 OR = 3 716 P <0 001 lower grade OR=3 574 P <0 001 lymph node invasion OR=2 053 P =0 004 and smaller lesion OR=1 762 P =0 033 were risk factors for retraction phenomenon while histologic type P =0 3 1 8 and patient age P = 0 612 were not By multivariate logistic regression analysis Luminal A subtype OR=9 877 P <0 001 lower grade OR=3 573 P <0 001 and lymph node invasion OR=2 730 P = 0 004 were independent risk factors for retraction phenomenon among which Luminal A subtype was the strongest one Conclusions Retraction phenomenon on the coronal planes obtained by ABVS is closely related with Luminal A subtype and may be an imaging feature of less aggressive behaviors of breast cancer.

Although previous reports showed drug-eluting stent (DES) could effectively inhibit neointima formation, in-stent restenosis (ISR) remains an important obstacle. The purpose of this study was to investigate different effects of paclitaxel on proliferation and cell cycle regulators between vascular smooth muscle cells (VSMCs) and vascular endothelial cells (VECs) of rats in vitro. The cultured VSMCs and VECs of rats from the same tissues were examined by using immunohistochemistry, flow cytometry and Western blotting in control and paclitaxel-treated groups. The results showed paclitaxel could effectively inhibit proliferation of VSMCs and VECs. However, as compared with VECs, proliferation of VSMCs in paclitaxel-treated group decreased less rapidly. The percentage of cells in G0-G1 and G2-M phases was reduced, and that in S phase increased after treatment for 72 h. The expression of cyclin D1 and B1, p27 and PCNA in VSMCs of paclitaxel-treated group was up-regulated, but that of p21 down-regulated as compared with VECs. It is concluded that there are significant differences in the expression of cell cycle regulators and proliferation rate between paclitaxel-treated VSMCs and paclitaxel-treated VECs, suggesting that the G1-S checkpoint regulated by paclitaxel may play a critical role in the development of complications of DES, which provides new strategies for treatments of ISR.

The effect of C-terminal region residues on the substrate specificity of a novel cyclic imide hydrolase (CIH), a recombinant cyclic imide hydrolase (CIH293), and its mutants deleted or substituted at C-terminus (CIH291, CIH290, KK292-293EE) was reported. The substrate specificity and kinetic parameters of the mutants were analyzed by both the spectrophotometric assay and high-performance liquid chromatography. Results show that the substrate specificity of mutants was not obviously changed, but slightly low for the affinity between the substrate and enzyme, compared with the wild-type enzyme, CIH293. In conclusion, the last three residues of CIH293 play an important role for the enzyme activity.

Objective To observe clinical efficacy of treating acute facial neuritis with routine acupuncture treatment and tube moxibustion therapy. Methods Totally 100 cases were divided into observation group (50 cases) and control group (50 cases) with random number table method. Both groups were treated with acupuncture on accupoints of Yifeng (SJ17), Dicang (ST4), Jiache (ST6), Xiaguan (ST7), Yingxiang (LI20), Taiyang (EX-HN5), Cuanzhu (BL2) of affected side, Hegu (LI4) of unaffected side. On the basis of routine treatment, observation group was given electronic tube moxibustion therapy, inserting the ipsilateral external auditory canal about 1 cm and waiting for burning out, 20 min each time. Control group received TDP to irradiate ipsilateral ear, 20 min each time. Treatment for both groups were once a day, 5 times as a treatment course, 2 d between each course, for 4 courses. House-Brakmann facial nerve functional index, temperature differences on face and retroauricular skin and ear pain duration were observed. Clinical efficacy was evaluated.
