Objective To investigate the change of expression patterns of miRNA in the serum and peripheral blood mononuclear cells (PBMC) of lung cancer and its significance.Methods Clinical case control study was employed.Establish the method of microRNA(miRNA) detection by real time quantitative PCR (RT-qPCR).peripheral blood of the study subjects were collected in First affiliated hospital of SooChow University from November 2011 to September 2012.Gender and age matched subjects whose median age was 64(40-85) included 61 lung cancer cases,48 healthy control and benign lung diseases.We used quantitative RT-PCR to assess miRNA expression pattern of-miR-20a,21,-25,-29,-31,-126,-129,-145 and -205 in peripheral blood.U6 was taken as reference,and the expression of miRNA were indicated as F =2-△Ct,ACt =CtmiRNA--CtU6.F represents relative change of miRNA expression compared to U6 in the same sample.SPSS 19.0 was used as statistical software; t test was used for comparison of two sets of samples One way ANOVA was used for multiple groups' comparison,and make multiple comparison by the S-N-K method if the result with a significant difference.Pearson correlation analysis were used for the relationship between two variables,Brown-Forsythe test was used for Ct value equality testing among multiple samples.P ＜ 0.05were regarded as statistically significant.Results miR-20a (F =271.64,P ＜ 0.01),miR-21 (F =2232.51,P＜0.01),miR-205 (F=45.13,P＜0.01),miR-29a (F=19.98,P ＜0.01),miR-25 (F=313.19,P ＜ 0.01) and miR-126 (F =32.38,P ＜ 0.01) were differently expressed in the serum of lung cancer patients and healthy control or benign disease control.miR-29a,miR-25,miR-126 was down regulated in the development of malignant lung disease; miR-31 elevated in lung cancer compared with healthy control,while miR-145 fell; miR-31 expression changed with various differentiation of lung cancer (F =5.22,P ＜ 0.01)itwas significantly increased in the moderate-differentiated cancer,but decreased when distant metastasis existed (especially bone metastasis).But in PBMC paired with the serum samples above,statistically significance was shown in lung cancer and healthy control group and benign lung diseases group in miR-126 (F=690.58,P＜0.01),miR-129 (F=26.66,P＜0.01),miR-145 (F=48.57,P＜0.01),miR-205 (F=308.61,P＜0.01).miR-25 (F=218.57,P＜0.01) and miR-31 (F=48.05,P＜0.01),were down regulated in the development of malignant lung disease.miR-20a,miR-29a were elevated in lung cancer compared to healthy controls,miR-21 was up-regulated when distant metastasis existed; the expression of miR-31 in serum and PBMC was negatively correlated (r =-0.369,P ＜ 0.05).Areas under ROC curve of miR-25 (S =0.906,P ＜ 0.01) and miR-126 (S =0.969,P ＜ 0.01) were statistically different.Conclusions miRNA may contribute to several steps of metastasis,including local invasion,extravasation or initial survival at a distant site,and metastatic colonization,or can affect the prognosis of lung cancer.The detection of miRNA in lung cancer provides a new clue to the research of its chronic progress.

Near-infrared (NIR) diffuse reflectance spectroscopy was used to analyze the impact of multi-class particle size of Chinese material medica (CMM) based on the spectral characteristics in overtone and combination region. Several types of CMM (60, 80, 100,120 mesh) were subjected to NIR spectra analysis. Spectral reproducibility was examined after sample repackage. The result showed that the effects of particle size on the NIR spectra were different according to different bands, in the combination region and first combination-overtone region. Spectroscopy intensity was proportional to the particle size and influence of particle size was greater as the wavelength increased. While in the second combination-overtone region, it was inversely proportional to particle size. To the sampling loading error, the result indicated that when the mesh number was larger than 60 mesh, the error was small. The appropriate particle size was clarified to guarantee the accuracy and reliability of NIR diffuse reflectance spectroscopy in CMM.

Objective To assess the clinical safety and effectiveness of transcatheter arterial embolization by using liquid medical glue ( FLA ) and super-selective catheterization technique in treating renal artery pseudoaneurysm. Methods During the period from Oct. 2009 to Jun. 2014, a total of 23 patients with angiography-proved renal pseudoaneurysm were treated with transcatheter arterial FLA embolization at authors’ hospital. The clinical data were retrospectively analyzed. A total of 28 pseudoaneurysms were detected in the 23 patients, which was caused by iatrogenic injury(18 cases, 21 lesions) or trauma(5 cases, 7 lesions). Super-selective catheterization with 3F micro-catheter was carried out. The micro-catheter was inserted into the parent artery of the pseudoaneurysm, which was followed by angiography. Once the pseudoaneurysm was confirmed by angiography, the mixture of FAL and iodized oil (1 ∶ 1) was injected into the pseudoaneurysm through the micro-catheter. The technical success rate, postoperative hematuria and renal function were determined. Results Successful embolization was achieved for all 28 pseudoaneurysms in 23 patients. The average volume of FAL used in embolization was 0.4 ml (0.2-1 ml). Ectopic embolization of the third-level vessel branches near the parent artery occurred in three cases , while no embolization of second-level vessel branch was observed. Persistent hematuria was seen in one patient even at two days after the treatment, whose pseudoaneurysm’s diameter was >2 cm, and embolization treatment with steel coil had to be performed, and bleeding stopped after the second treatment. During the follow-up period lasting for 3 months, no recurrence of hematuria was seen in the remaining patients. Mild elevation of serum creatinine after the treatment was observed in 4 patients. Conclusion The results of this study indicate that FAL together with the help of micro-catheter super-selective catheterization can effectively and reliably obstruct renal pseudoaneurysm with higher technical success rate and lower re-bleeding rate.

Objective To assess the validity and safety of arterial embolization with medical adhesive in treating peripheral artery pseudoaneurysms(PSA).Methods 25 cases of peripheral artery PSA embolized with Fuaile medical adhesive(FMA) were analyzed retrospectively.25 patients included 28 PSA.Super-selective transcatheter arterial embolization was performed in 19 patients (22 PSA) using 3F microcatheter and 6 PSA in 6 patients were embolized through puncturing directly.All the lesions were treated with mixtures of FMA and iodized oil (1：1) during the radiography.The clinical efficacy and complications were recorded.Results The success rate of embolization was 100% during the operation (28/28), and the average volume of FMA used was 1.8 mL(0.5-5.5 mL).One patient with PSA(d>2 cm) still have hematuria 2 days after the operation.The hematuria disappeared after embolization with micro-coil following re-angiography.Bleed stopped after the second embolization with FMA in one patient with brachial artery PSA.No one developed complications associated with therapy and occurred rebleeding in the follow-up period time (3 months).Conclusion The mixtures of FMA and iodized oil can be a useful alternative embolic agent for the treatment of peripheral artery pseudoaneurysm with high success rate, short operation time and definite clinical effect.
