Purpose To explore the value of ultrasound contrast time-intensity curves in hepatic tumor qualitative diagnosis and evaluation of tumor ablation effect. Materials and Methods Forty-two patients who were clinically diagnosed as hepatic cancer or cirrhosis underwent contrast enhanced ultrasound for the tumor lesions within the liver, dynamic analysis of the lesions were executed with software SonoLiver CAP, the nature of the tumors were determined and the results were compared with those of the enhanced MRI. Ultrasound guided biopsy was followed with radiofrequency ablation treatment, two-dimensional and contrast enhanced ultrasound were executed two weeks after the ablation, and the results were compared with enhanced MRI findings during corresponding period. Results 52 tumor nodules were found with two-dimensional and color Doppler ultrasound, 65 (33 hyperplastic nodules, 32 malignant lesions) with CEUS, 65 (21 hyperplastic nodules, 44 malignant lesions) with ultrasound contrast time-intensity curves, and 61 (20 hyperplastic nodules, 41malignant lesions) with contrast enhanced MRI; pathological examination revealed that 26 of the lesions were benign and 39 were malignant;there was statistically significant difference (χ2=4.561, P<0.05) between the results of ultrasound contrast time-intensity curves and simple contrast enhanced ultrasound for the assessment of the nature of tumor;no statistically significant difference (χ2=0.003, P>0.05) was found between ultrasound contrast time-intensity curves and enhanced MRI for the assessment of the nature of tumor;there was statistically significant difference (χ2=5.298, P<0.05) between ultrasound contrast time-intensity curves and simple contrast enhanced ultrasound for the assessment of whether the tumor was malignant or benign, when taking biopsy results as the reference standard. Conclusion With ultrasound contrast time-intensity curves, dynamical, intuitive, and quantitative evaluation can be obtained for the perfusion differences between the lesion and the surrounding liver parenchyma, which provides more accurate information for qualitative diagnosis of hepatic tumors thus contains great application value in the evaluation of the effects of radiofrequency ablation for hepatic tumors.

The molecular targeted therapy method using microRNAs(miRNAs)is gradually stepping into people′s vision. miRNAs affect colorectal cancer progress via abnormal expression in tumor cells or micro-environment. The high or low expressions of miRNAs in specific tissues probably have an impact on the expressions of oncogenes,tumor suppressor genes or other aspects including the surrounding environments,the metastases and the drug tolerance of tumors,thus contributing to curing the colorectal cancer. Nowadays, miRNA has entered the stage of animal experiments.

Background Small incision lenticule extraction (SMILE) is increasingly used for myopia.However,the size of the incision varied in different operators.The influence of 2 mm micro-incision SMILE on postoperative diopter and aberrations is not clear yet.Objective The aim of the current study was to perform a clinical analysis of the efficacy,safety,stability and predictability of 2 mm micro-incision SMILE and investigate the influence of preoperative sphere and cylinder power on postoperative aberrations.Methods A serial cases observational study was carried out under the approval of Ethic Committee of Tianjin Eye Hospital and informed consent of each patient.Fifty-five eyes of 31 subjects with myopia and myopic astigmatism were enrolled in this study in Tianjin Eye Hospital from January to April 2013 and a 2 mm micro-incision SMILE was performed on the eyes.Follow-up visits were performed at 1 week,1 month and 6 months after operation.Uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA),manifest and cycloplegic refraction were examined at each postoperative time points to evaluate the efficacy,safety,stability and predictability of 2 mm micro-incision SMILE.Wave-front aberrations were measured by WaveScan aberrometer.Repeated measurement analysis of variance was used for the comparison of the differences of aberrations before and after the surgery.And the differences between various follow-up visits were compared with LSD-t test.The relationship between preoperative sphere or cylinder power and aberrations postoperatively were analyzed by Spearman rank correlation.Results At 1 week,1 month and 6 months postoperatively,the effective index was 1.2,and the safety indexes were 1.2,1.2 and 1.5 respectively.The spherical equivalent remained 0.00 D at each postoperative time point.And 96.4％ and 97.8％ of eyes were within ±0.5 D of intend correction and 100％ were within ± 1.0 D of the intend correction at 1 month and 6 months postoperatively.Vertical coma (Z7) and spherical aberration (Z12) were significantly raised at 1 week,1 month and 6 months after surgery compared with the values preoperatively (Z7:t =9.668,10.607,9.772,all at P ＜ 0.001 ;Z 12:t =-6.227,-6.923,-7.441,all at P＜0.001).The Zernike coefficients were relatively symmetrical between various time points postoperatively (all at P＞0.05).Third-order to sixth-order aberrations and higher order abberration (HOA) showed significant increase at various time points after the surgery compared with the values before surgery (all at P＜0.05),and no significant differences were seen between various follow-up visits (all at P＞0.05).Positive correlations were found between preoperative sphere and S3,S4 and HOA at 1 week,1 month and 6 months postoperatively (P＜0.05).Negative correlations were found between preoperative cylinder and S3,S4 and HOA at postoperatively various time points (all at P＜0.05).In addition,significant positive correlations were seen between Z7 and preoperative cylinder as well as between Z12 and sphere preoperatively,and negative correlations also were observed between Z7 and preoperative sphere as well as between Z12 and cylinder preoperatively at each follow-up visits(all at P＜0.05).Conclusions SMILE with 2 mm micro-incision is a safe,effective,stable and predictable procedure for myopic and myopic astigmatism eyes.The aberrations and Zernike terms remain stable after surgery until 6 months although these parameters present elevation to a certain extent.Preoperative SE and astigmatism power affect postoperative aberrations.

Objective: To observe the relationship among blood pressure, left ventricular hypertrophy (LVH) and sinus heart rate turbulence (HRT) in patients with essential hypertension (EH) and its clinical significance. Methods: A total of 125 EH patients received 24h ambulatory blood pressure monitoring, dynamic electrocardiogram and echocardiography examination in order to measure 24h mean blood pressure, turbulence onset (TO), turbulence slope (TS) and left ventricular mass index (LVMI). According to 24h mean blood pressure, patients were divided into hypertension stage 1 group (n=46), stage 2 group (n=41) and stage 3 group (n=38); according to LVMI, patients were divided into non- LVH group (n=74) and LVH group (n=51). TO and TS were compared among all groups. Results: TO: Compared with hypertension stage 1 and stage 2 group, there was significant increase in TO [(-2.48±1.75) % vs. (-1.86±1.19) % vs. (-0.87±1.14) %] in hypertension stage 3 group, and that of stage 2 group was significantly higher than that of stage 1 group（P<0.05～<0.01）; compared with non- LVH group, there was significant increase in TO [(-0.15±0.45) % vs. (1.08±1.19) %] in LVH group, P<0.01. TS: compared with hypertension stage 1 and stage 2 group, there was significant decrease in TS [(3.76±1.87) ms/RR interval vs. (2.33±1.48) ms/RR interval vs. (1.55±1.06) ms/RR interval] in hypertension stage 3 group, and that of stage 2 group was significantly lower than that of stage 1 group （P<0.05～<0.01）; compared with non- LVH group, there was significant decrease in TS [(4.76±1.75) ms/RR interval vs. (3.02±1.08) ms/RR interval] in LVH group, P<0.01. Conclusion: The higher the blood pressure is, the more abnormality the heart rate turbulence is; the heart rate turbulence abnormality of patients complicated with LVH is more severe than that of non- LVH patients in patients with essential hypertension, so heart rate turbulence is help to judge prognosis and guide treatment.

Objective To study the immunophenotype and chromosome karyotype of 57 adult patients with newly?diagnostic acute lymphoblastic leukemia(ALL). Methods The immunophenotype and chromosome karyotype of 57 adult patients with newly?diagnostic ALL were determined by using flow cytometer and karyotyping,and then the clinical characteristics and significance were analyzed. Results In patients with B cell acute lymphoblastic leukemia(B?ALL),the expression of CD19 and CD22 were significantly higher than CD10 and CD20(P<0.05). The expression of CD7 and CD3 were much higher in patients with T cell acute lymphoblastic leukemia(T?ALL). As for the early antigen,patients of all subtypes of ALL showed high expression rate of CD34 and CD38. In addition,the HLA?DR was only detected in B?ALL. There was no difference in comparison with clinical characteristics,total rate of CR and rate of relapse between ALL with and without myeloid antigen expression. The expression rate of CD34 and HLA?DR was higher in My+?ALL(P<0.05). The relapse rate was much higher in these patients with abnormal karyotype than other pa?tients(P<0.05). Patients with high?risk karyotype showed higher expression rates of CD20 and CD3 than those with standard?risk. Conclusion The immunophenotypes and chromosome karyotypes show obviously heterogeneous features,and the patients with abnormal karyotypes have higher relapse rate. These above mentioned methods are applicable for the diagnosis and individualized treatment of ALL patients.

Objective To investigate the potential of inflammatory markers for short-term prognosis of acute cerebral infarction.Methods A total of 272 consecutive patients with acute cerebral infarction were divided into a high hs-CRP group (hs-CRP level ＞3 mg/L) and a low hs-CRP group (hs-CRP level ≤3 mg/L),and their general information and medical history were collected.The Trial of Org 10172 in Acute Stroke Treatment (TOAST) stroke subtype classification was conducted and scores of the National Institutes of Health Stroke Scale (NIHSS),the Barthel index (BI) and the modified Rankin scale (mRS) were collected after admission.White blood cell count,blood glucose,blood homocysteine (Hcy) and C-reactive protein were measured within 24 hours following admission.Multivariate Logistic regression analysis was performed to identify independent risk factors for short-term prognosis of acute cerebral infarction.Results Between the high hs-CRP group and the low hs-CRP group,there were significant differences in the incidences of atrial fibrillation history,cardiogenic embolism of TOAST,blood homocysteine,blood glucose,white blood cell count,NIHSS,BI and mRS score 1,7,14 days after admission (P＜0.05 for all).The hs-CRP level (OR=0.876,P＜0.001,95％ CI:0.817-0.917),white blood cell count (OR=1.137,P=0.029,95％ CI:1.013-1.275),lipid metabolism disorders (OR=2.863,P＜0.001,95％ CI:1.561-5.250),and BI score (OR=1.038,P=0.047,95％ CI:1.001-1.077) 1 day after stroke were independent risk factors for short-term prognosis of acute cerebral infarction.Conclusions Increased levels of the inflammatory marker hs-CRP and elevated white blood cell count may be independent risk factors for short-term prognosis of acute cerebral infarction.

Aim To explore the mechanism of tetram-ethypyrazine ( TMP) in the inhibition of cancer cell in-vasion and metastasis, by investigating the effect of TMP on cell migration, cell invasion and cytoskeleton of HepG2 cells. Methods Using HepG2 cells as tar-get cells, cell migration of different concentrations of TMP on HepG2 cells was assayed by the scratch wound healing assay. Matrigel cell invasion assay was used to detect the effect of TMP on the invasion of HepG2 cells. The effect of TMP on cytoskeleton of HepG2 cells was detected by high content screening ( HCS ) . Results TMP inhibited the migration of HepG2 cells, and showed a time-dependent and dose-dependent manner. Moreover, TMP significantly inhibited the in-vasion of HepG2 cells ( P<0. 01 ) , and showed a cer-tain time-dependence. Furthermore, compared with control group, a significant decrease in HepG2 cy-toskeleton area was found in a dose-dependent manner ( P<0. 01 ) . Conclusion TMP can inhibit the migra-tion and invasion of HepG2 cells, and it has the poten-tial to resist tumor metastasis, and the mechanism may be associated with TMP significantly decreasing the number and area of cytoskeleton, and inhibiting the re-arrangement of cytoskeleton.
