Objective To study the clinical values of polyvinyl alcohol chemoembolization and bronchial arterial infusion(BAI) in interventional therapy of central bronchogenic carcinoma.Methods 45 pathologically proved cases of central bronchogenic carcinoma in mid or late period were randomly divided into two groups(control group in 24 cases and experimental group in 21 cases).After detecting the nourishing arteries of bronchogenic carcinoma with angiography,the treating processes were performed.Control group : anticancer drugs were poured into bronchial artery.Experimental group : the feeding arteries of tumors were co-axially superselective catheterized with microcatheters,the anti-neoplasm agents were poured into everyone of feeding arteries according to the blood supply,then the feeding arteries were embolized by polyvinyl alcohol.Results Control group : the obvious effective rate(CR+PR) was 50%.Experimental group:the obvious effective rate was 90.4%.Two cases in control group obtained the chances of radical operation and chemotherapy were performed after operation,the other 22 cases were undergone synthetic treatment.Seven cases in experimental group obtained the chances of radical operation and chemotherapy were performed after operation,14 cases were undergone synthetic treatment.Three cases in control group died and none of in experimental group died in the follow-up of 2~24 months.Conclusion The short-term effect of polyvinyl alcohol embolization is better than those of BAI for interventional therapy of central bronchogenic cancer,but the long-term effect needs a large number of cases to access the real clinical value.

Objective To investigate the psychological conditions and the quality of life of premenopausal breast cancer patients. Methods 5 Level-Three Grade-I hospitals in Beijing were selected to conduct outpatient surveys on premenopausal breast cancer patients who returned for further consultation between October 2010 to September 2012. Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) as well as Functional Assessment of Cancer Therapy-Breast (FACT-B) were used. Investigated breast cancer patients were divided into two groups: long-term condition group (more than 3 years after surgery) and short-term condition group (less than 3 years after surgery).Differences between the two groups in SAS, SDS and FACT-B were compared. Results 65 quality questionnaires returned, including 35 from the long-term condition group and 30 from the short-term condition group. The scores of SAS and SDS were significantly lower in the long-term condition group than in the short-term condition group (P<0.001). The scores of FACT-B was significantly higher in the long-term condition group than in the short-term condition group (P<0.001). Conclusion The breast cancer patients more than 3 years after surgery are in better psychological status and quality of life.

Objective To study the protective effect of polyene phosphatidylcholine on hepatic injury induced by oxaliplatin and 5?fluorouracil. Methods A subcutaneous tumor model was established by transplanting colocarcinoma HCT116 cells into 30 nude mice,which were random?ized into three groups. The polyene phosphatidylcholine group was injected with polyene phosphatidylcholine(85 mg · kg-1 · d-1)and 5?fluorouracil (20 mg·kg-1·d-1)for 7 days,and then injected with oxaliplatin(6 mg·kg-1·d-1)for 1 day. The hepatic injury group was injected with 5?fluoroura?cil(20 mg·kg-1·d-1)for 7 days and oxaliplatin(6 mg·kg-1·d-1)for 1 day. The tumor?bearing blank group was injected with normal saline. Hepat?ic injury was observed with ultrathin pathological sections. Liver homogenates were prepared to detect superoxide dismutase(SOD)and catalase (CAT)activity. Results In the hepatic injury group,pathological sections revealed dissolved cellular cytoplasm,mitochondrial membrane dam?age,cell membrane edema,and fuzzy,sinusoidal cell expansion . There were no obvious hepatic injuries observed in the polyene phosphatidylcho?line group. The expression of SOD and CAT were lower in the hepatic injury and polyene phosphatidylcholine groups compared to the tumor?bear?ing blank group(P<0.05). The expression of SOD and CAT were higher in the polyene phosphatidylcholine group compared to the hepatic injury group(P<0.05). Conclusion Polyene phosphatidylcholine has a protective effect on hepatic injury induced by oxaliplatin and 5?fluorouracil, which may be related to its effect on membrane repair and inhibition of oxidative stress.

Objective To examine cardiotoxicity of anthracyclines and trastuzumab in patients with breast cancer by two dimensional speckle tracking imaging. Methods Fifty-eight human epidermal growth factor receptors-2 (HER2) positive patients with breast cancer treated by anthracyclines and trastuzumab were monitored by echocardiography before treatment (Group A), after completion of anthracyclines (Group B), and at follow-up of 3 months (Group C) and 12months (Group D) after using trastuzumab. LVEDD, IVSTD, PWTD, LVEDV, LVESV were measured in the apical four- and two-chamber views. Left ventricular ejection fraction (LVEF) was measured using a modified Simpson's biplane method. Global longitudinal strain (GLS) and longitudinal strain rate (LSR) were calculated via Qlab8.0 analysis software off-line. Results LVEDDs in A-D groups were (47.95 ±4.12), (48.45 ±4.02), (48.91 ±3.83) and (49.98 ±3.72) mm, respectively, and LVEDVs were (108.70 ±21.26), (111.90 ±20.91), (113.50 ±20.25) and (119.20 ±20.02) ml, respectively. LVEDD, PWTD [(9.14 ±0.76) mm vs. (9.00 ±0.82)mm], LVEDV, LVESV [(54.60 ±14.58) ml vs. (50.97 ±14.35) ml] were increased in group B compared with those in A group (all P<0.05). LVEDD and LVEDV were increased in group C(P<0.05) compared with those in group B. CLVEDD, LVEDV, LVESV [(59.18±13.88) ml vs. (55.23± 13.81) ml] were increased in group D compared with group (P<0.05). Differences of LVEF between group C and group D were statistically significant[(59.48±2.62) % vs. (62.00±1.40) %, P<0.001]. Differences of GLS [(-21.16±2.33)%, (-19.76±1.98) %, (-19.22±1.89) % and (-18.74±1.79) %, respectively, P<0.001] and LSR [(-1.27±0.11), (-1.22±0.09), (-1.17±0.07) and (-1.14±0.06) /s, respectively, P<0.001] among four groups had all statistically significant. Conclusions Longitudinal left ventricle systolic function are impaired in patients with breast cancer treated by anthracyclines and trastuzumab. GLS and LSR of myocardium traced by two dimensional speckle tracking imaging would be useful for early evaluation of the severity.

Objective To observe the correlation between cardiac two-dimension global strain-speckle tracking imaging (2D-STI) and coronary artery disease index (CADi) scores in patients with acute myocardial infarction(AMI). Methods Eighty patients with AMI were chosen and given myocardial motion analysis using 2D-STI. The global longitudinal strain (GLS), global radial strain (GRS) and global circumferential strain (GCS) was calculated. All patients were given scoring according to CADi scores standard by coronary angiography. The correlations between 2D-STI indexes and CADi scores were analyzed. The area under curve(AUC) of the receiver operating characteristic curve (ROC) of critical coronary stenosis was calculated. Results GLS, GRS and GCS was all correlated to CADi scores (r=0.670, -0.621, 0.525, all P < 0.01). The sensitivity, specificity and AUC of GLS for critical coronary stenosis was 82.35%, 80.43% and 0.831. The sensitivity, specificity and AUC of GCS for critical coronary stenosis was 76.47%, 76.09% and 0.797. The sensitivity, specificity and AUC of GRS for critical coronary stenosis was 97.06%, 78.26% and 0.880. The AUC of GLS and GRS was larger than that of GCS, and the sensitivity, specificity for critical coronary stenosis was larger. Conclusions 2D-STI indexes have correlation with CADi scores. GLS and GRS has correlation with coronary artery stenosis.

Objective To evaluate combined sampling at multiple sites of gastric mucosa for Helicobacter pylori (HP) culture.Methods A total of 258 patients with upper gastrointestinal symptoms received 13C-urea breath test between August 2014 and May 2015.During endoscopy,gastric mucosa biopsy samples from the lesser curvature of the antrum (A),the greater curvature of the antrum (B),gastric angle (C) and the body of the stomach (D) were collected to isolate HP strains.The positive rates of HP based on combined sampling and single site sampling were compared with a Nemenyi test.Results Consistency between 13C-urea breath test and HP culture was 82.56％.There was significant difference between the single site sampling and two-site sampling in the positive rate of HP,except for the body of the stomach (P＜0.05).There was significant difference in the positive rate of HP between the single site sampling and three-site sampling (P ＜ 0.05).There was no significant difference between any two-site sampling in the lesser curvature of the antrum and the body of the stomach,gastric angle and the body of the stomach,the greater curvature of the antrum and the body of the stomach,and any three-site sampling (P＞0.05).Conclusion The combined sampling of the lesser curvature of the antrum and the body of the stomach have the highest cost-effectiveness in HP culture compared with the single site sampling and three-site sampling.

Objective The incidence of post-operative hyperbilimbinemia, which is associated with poor outcomes in patients, was reported to be increased in recent years though it has been a rare complication for cardiac operations. Post-opera-tive impairment of liver function is highlighted. We evaluated the incidence and prognosis of post-operative hyperbiliruhinemia in adult patients who underwent cardiotomy with extracorporeal membrane oxygenation (ECMO) support. Methods Sixty-five adult patients who had received ECMO support after cardiac surgery from 2004 to 2008 were enrolled and evaluated retrospec-tively. Post-oporative hypethilirubinemia was defined as the serum level of the total bilirubin more than 51.3 μmol/L during postoperative period. Demographic and clinical data included gender, age, types of surgery, perioperative hemodynamic param-eters, biochemical variables, duration of the ventilation support, ICU stay and outcomes. Results The mean age of the pa-tients was (50.1 ± 13.9) years, forty-six patients(70.8%) were male. The main cardiac procedures were heart transplanta-tion for 9 patients, coronary artery bypass grafting and/or valve operations for 47 patients, congenital heart disease correction for 4 patients and other operations for 5 patients. Among all patients, fifty-one patients(78.5%) were weaned from ECMO succeas-fully and thirty-thrce patients were discharged from hospital. The overall mortality rate was 49.2%. Overall incidence of post-operative hyperbilirubinemia was 55.4%. In patients with postoperative hyperbilirubinemia, the mean peak value for serum to-tal bilirubin was 104.8 (68.5-156.7) μmol/l. The hospital mortality in the hyperbilirubinemia group was significantly higher than that in the non-hyperbilirubinemia group(66.7% vs. 27.6%, P <0.01). Moreover, postoperative hypethilirubinemia (adds ratio = 3. 895, 95% confidence interval, 1.088 - 13.947 ; P = 0.037) and SOFA score (odds ratio = 1.214, 95% confidence interval, 0.987 - 1.494, P = 0.047) and APACHE Ⅲ score (odds ratio = 1.096, 95% confidence interval, 1.028 - 1.169 ; P = 0.004) were associated with hospital mortality after adjusting for preoperative levels of the total bilirubin, direct bilirubin, gender and age. Conclusion Postoperative hyperbilirubinemia is one of the complications in adult patients who undergo cardiotomy with ECMO support, and is associated with increased hospital mortality.

Objective To research the fibrosis characteristics of Atrial Fibrillation(AF) patients under microscope and its effect to post-operative sinus conversion of Radiofrequency ablation treatment.Methods Based on Lefi Atrial Dimension (LAD).Left atrial appendage tissue samples of 60 AF patients who received bipolar radiofrequency ablation treatment during open heart surgery between July and December 2011,were divided into 4 groups:group a (LAD≤50 mm),group b (50 mm ＜ LAD≤60 mm),group c (60 mm＜ LAD ≤70 mm),group d (LAD ＞ 70 mm),15 patients in each group.The levels of atrial muscle fibrosis and cell size differences are compared for colored slides of samples.Research are done for the difference of sinus rhythm restoration rate among the 4 groups based on ECG records at immediate,leaving hospital,and 3,6,12 months postoperative are collected for all groups.Results Differences of CVF and atrial muscle cell size measured under microscope are statistically meaningful(P ＜ 0.001).Sinus rhythm restoration rate differences at 6 month(P =0.039) and 12 month (P =0.037) post-operative are statistically meaningful.Further,immediate,leaving hospital,and 3,6,12 months postoperative sinus rhythm restoration rates are 93.3％,93.3％,93.3％,100％,100％ for group a,80.0％,73.3％,80.0％,80.0％,80.0％ for group b,66.7％,66.7％,66.7％,73.3％,66.7％ for goup c,and 53.3％,53.3％,53.3％,60.0％,60.0％ for group d respectively.Conclusion For rheumatic heart valve diseases patients who at 6 and 12 month post-operative,the greater the LAD,the higher the atrial fibrosis level,the greater the cell size,the lower the sinus rhythm restoration rate is.
