Objective BALB/C mice were inoculated subcutaneously with hepatoma 22 (H22) cells, and the treatment effect of thalidomide and intratumor injection of ethanol extract of Scutellaria Barbata (SB) on tumor growth were evaluated. Methods In vitro, mouse H22 liver cells were cultivated, and H22 cells in the logarithmic growth phase were tested. SB was extracted in the ethanol recirculation. A total of 28 BALB/C male mice inoculated subcutaneously with H22 cells were randomly divided into 4 groups, 7 mice per group. Group A:intragastric administration with thalidomide. Group B:SB intratumor injection. Group C:combination of thalidomide and SB with the same administration as Group A and Group B. Group D (control group):1% Ethanol 0.2～0.5 mL intratumor injection. Tumor volumes of four groups were observed and the tumors were weighed. The microvessel densities (MVD) of all transplantation tumors were measured by immunohistochemical staining with anti-CD31 monoclonal antibody. Results There were statistically significant differences between Group C and Group A (P 0.05). The studies showed statistically differences between Group C and Group A (P

Objective To explore the correlation of epicardial adipose tissue (EAT) volume with atrial fibrillation (AF) and its recurrence after radiofrequency ablation (RA).Methods Eighty-five AF patients (AF group) and 90 non-AF patients (control group) were chosen between January 2014 and May 2016.Their EAT volumes were measured by CT scanning.Patients in AF group after RA were followed up 6-18 months,and the recurrence of AF was recorded.The recurrence of AF within 3 months of RA was defined as blanking recurrence group (n =27) and non-blanking recurrence group (n =58),and that after 3 months of RA was defined as the 1 ong-term recurrence.Results The total EAT volume and left atrial EAT volume were significantly larger in blanking recurrence group than in non-blanking recurrence group [(118.71 ±28.94) cn3 vs (97.73 ±24.86)cm3,(29.98 ±8.09)cm3 vs (23.11 ±8.30)cm3,t =6.219,4.451,P ＜ 0.01].Multivariate logistic resgression analysis showed that total EAT volume and left atrial EAT volume were the independent risk factors for AF.All showed that total EAT volume and left atrial EAT volume were the independent risk factors for blanking recurrence.The incidence of long-term recurrence was significantly higher in blanking recurrence group [40.7％ (11/27)] than in non-blanking recurrence group [15.5 ％ (9/58)] (x2 =7.142,P ＜ 0.05).Conclusions The incidence of AF is higher in patients with a Iarger total EAT volume and a larger left atrial EAT volume and AF is easier to recur even though after RA.

Objective To study the relation of epicardial adipose tissue (EAT) thickness with 1eftventricular remodeling and dysfunction in dilated cardiomyopathy (DCM) patients.Methods One hundred and twenty DCM patients who received treatment from Febuary 2012 to February 2016 were served as DCM group,and 76 healthy subjects undergoing physical examination were served as control group.Their left ventricular end-diastolic diameter (LVEDD),left ventricular end systolic diameter (LVESD),left ventricular end diastolic volume (LVESV),left ventricular end systolic volume (LVEDV),left ventricular end diastolic volume index (LVEDVI),left ventricular end systolic volume index (LVESVI),sphericity index (SI),leftventricular ejection fraction (LVEF),and EAT thickness were measured by routine cardiac ultrasonography and compared between two groups.Results The levels of LVESD,LVEDD,LVESV,LVEDV,LVESVI,LVEDVI and EAT thickness in DCM group were significantly higher,and the levels of LVEF,SIS and SID in DCM group were significantly lower (P＜0.05).The EAT thickness in DCM group with NYHA class Ⅱ,Ⅲ,Ⅳ was (8.1 ± 1.8),(7.8 ± 2.0),(7.9 ± 1.7) mm,and there was significant difference (F=1.973,P＞ 0.05) Linear correlation analysis showed that the EAT thickness was positively related with the LVESD,LVEDD,LVESV,LVEDV,LVEDVI,LVESVI,SISand SID (r =0.247,0.231,0.256,0.267,0.293,0.281,0.261,0.237,P＜0.05).There was no relationship between EAT thickness and LVEF (r =0.132,P＞ 0.05).Logistic multifactor regression analysis showed that EAT thickness was an independent risk factor for left ventricular remodeling in DCM patients (OR =0.793,95％CI:0.431-1.734,P =0.039).Conclusions The EAT thickness is significantly related with the left ventricular remodeling and can be used as an independent risk factor for predicting left ventricular remodeling in DCM patients.

Objective To evaluate the diagnostic accuracy of ultrasound bladder detrusor wall thickness (DWT) measurement for female bladder outlet obstruction (FBOO) and investigate the application of this non-invasive method for diagnosis of FBOO.Methods DWT was measured by linear ultrasound (7.5 MHz) either at a filling volume of 50％ of cystometric capacity or at 250 ml filling in 93 women undergoing pressure flow study (PFS) for lower urinary tract symptoms (LUTS).FBOO was defined as maximal flow rate (Qmax) of less than 12 ml/s combined with a detrusor pressure at maximal flow rate (Pdet Qmax)greater than 25 cm H2O.All the patients were divided into 2 groups according to FBOO and non-FBOO.The age,urodynamic parameters and DWT of the 2 groups were compared.Meanwhile DWT was evaluated for diagnosing BOO through receiver operating characteristic (ROC) curve.ResultsThe age (61.2 ± 8.3 vs 59.9 ± 7.7 years,P =0.44) and maximal cystometric capacity (292.2 ± 82.3 vs 308.1 ± 87.5 ml,P =0.37 ) between the 2 groups had no significant difference.DWT was significantly higher ( P =0.00 ) in FBOO group (42 cases,DWT 1.8 ±0.3 mm) compared to non-FBOO group (51 cases,1.4 ±0.2 mm).Furthermore maximal detrusor pressure (43.1 ± 11.2 vs 16.2 ± 7.1 cm H2O,P =0.00),Pdet Qmax (34.3 ±8.2 vs 13.1 ±7.8 cm n2O,P =0.00),Qmax(7.4 ±3.2 vs 17.4 ±4.1 ml/s,P =0.00),voided volume (157.1 ±63.7 vs 251.2 ±77.4 ml,P=0.00) and post-void residual volume (117.5 ±71.3 vs 37.7 ± 18.1 ml,P =0.00) had significant differences between the 2 groups.For a diagnosis of FBOO,DWT of 1.9 mm or greater had a positive predictive value of 100％,a negative predictive value of 62％,specificity of 100％ and sensitivity of 38％.ROC analysis revealed that DWT had a high predictive value for FBOO with an area under the curve of 0.88 ± 0.06.Conclusions Ultrasound DWT measurement for FBOO is non-invasive,convenient and reliable.DWT 1.9 mm or greater assessed by ultrasound has a high predictive value and specificity for FBOO and can replace PFS in some extent.However,this cutoff value needs to be validated in multiple center and larger population study.

Objective To study the significance of c-met mRNA in axillary drainage after operations for breast cancer. Methods RT-PCR assay was used to examine c-met mRNA in axillary drainage after operations in 52 cases of breast cancer. The relationships between the expression of c-met and the tumor size, metastatic lymph nodes, the expressions of estrogen receptor (ER), progesterone receptor (PR) and c-erbB-2 were analyzed, respectively. In addition, the effect of douching operative field with 5-FU and distilled water on the expression of c-met mRNA was also analyzed. Results ①The proto-oncogene c-met mRNA could be detected in axillary drainage after operations for breast cancer by RT-PCR, and its positive rate was higher than that in routine pathological detection for micrometastasis in the axillary lymph nodes (P

Objective To systematically evaluate the safety of high dose atorvastatin (80 mg daily) in Chinese patients. Methods Randomized controlled trials (RCTs) investigating 80 mg/ d atorvastatin vs. low-dose atorvastatin or placebo or blank were electionically retrieved in date bases of EMbase, PubMed, the Cochrane Library, WanFang, CNKI and WeiPu. Meta-analysis was performed using RevMan 5. 2 and Stata 11. 0 software. Results A total of 20 RCTs involving 2282 cases were included. The results of meta-analysis showed no significant differences betweent the 80 mg/ d atorvastatin group and the control group in the incidence of gastrointestinal adverse events (RR 1. 53, 95% CI 0. 85-2. 76, P = 0. 16), hepatic adverse events (RR 1. 53, 95% CI 0. 99 - 2. 36, P = 0. 05), muscular adverse events (RR 1. 51, 95% CI 0. 92 -2. 49, P = 0. 10), serious hepatic injuries ( RR 2. 33,95% CI 0. 88 - 6. 20, P = 0. 09) and serious muscular myopathies (RR 1. 40, 95% CI 0. 46 - 4. 30, P = 0. 56). Subgroup analysis by type of cotrast media used and durations of taking 80 mg/ d atorvastatin showed there were higher risks of gastrointestinal adverse events in the 80 mg/ d group when compared to blank control ( RR 4. 22, 95% CI 1. 11 - 16. 04, P = 0. 03). Conclusions The current evidence shows that 80 mg / d atorvastatin may be relatively safe in terms of adverse events in gastrointestinal tract, liver and muscular system, and relatively has risk in causing severe liver injuries and myopathies. With limited quantity and quality from the RCTs available, more high quality RCTs are needed to verify the above conclusion.

Objective To observe the correlation of estrogen,fasting insulin(FINS),fasting plasma glucose (FPG),glycosylated hemoglobin(HbA1c),blood lipids and carotid arteries -membrane thickening(IMT)in the postmenopausal women with type 2 diabetes.Methods 63 postmenopausal women with type 2 diabetes were divided into normal IMT group(group A),IMT thickening group(group B),plaque group(group C)according to the vascular ultrasound carotid artery intima thickness,at the same time 15 cases of healthy physical examination as control group (group D).All of the groups were detected the plasma total cholesterol(TC),high-density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol(LDL-C),fasting insulin(FINS),fasting plasma glucose(FPG),gly-cosylated hemoglobin(HbA1c),follicle-stimulating hormone(FSH),estradiol(E2).Results Compared with group A,the levels of FINS,IR,HbA1c,TC,LDL-C in group C was higher(t=16.83,14.44,2.50,2.38,2.42,all P<0.01 or P<0.05),however,the results of E2,HDL-C was decreased(t=7.32,5.51,all P<0.01).The levels of FINS,HbA1c,TC,LDL-C,FSH,IR in group D was lower than those of group C(t=19.74,36.44,8.64,7.95, 27.13,6.71,all P<0.01),On the contrast,the levels of HDL-C,E2 were elevated(t=11.34,8.72,all P<0.01). The Pearson's correlation analysis showed that E2 had negative correlation with FINS,IR,TC,LDL-C (P<0.01 or P<0.05).E2 had positive correlation with HDL-C(P<0.05).Logistic regression analysis showed that IMT and FINS,IR,HbA1c,LDL-C were positively correlated(OR=2.94,72.63,27.30,98.18,all P<0.01),while nega-tively correlated with E2 levels(OR=2.94,P<0.01).Conclusion The increased level of estrogen was a protective factor of carotid artery atherosclerosis in postmenopausal women with type 2 diabetes.
