50%) underwent renal artery stent implantation and percutanous coronary intervention, only 10 of them with merely renoarterial stenosis undergone renal artery stent implantation. The successful rates of the procedure and complication together with the volumes of contrast media were recorded respectively. And the serum creatitine before and 12 hours after the successful procedure were also measured. Results Both rates of procedural success and complication were similar among the three groups. The serum creatitine levels, 12 hours after the procedure, showed no difference in comparing with the baseline. Conclusion Non-ionic contrast media (Iopamiro 370) could be safely used in patients with RAS.

Objective To evaluate the efficacy and safety of Firebird drug-eluting stent (DES) in the treatment of de novo native coronary artery lesions.Methods 60 patients underwent coronary artery stenting with Firebird DES (Firebird group), 52 patients with Cypher DES (Cypher group) and another 20 patents with Mustang bare stents (Mustang group). The instant and short term follow-up outcomes were compared among the three groups. Results The procedural successful rates (98.3%vs 100.0%vs 100.0%), nitrate cessation (32.1%vs 33.3%vs 29.4% ), re-admission(5.6%vs8.3%vs11.7%) and follow-up rates (88.3%vs 92.3%vs 85.0%) did not significantly differ among the three groups. As compared with Firebird group, patients in Mustang group had more MACE(17.6%vs 0), higher occurrence rates of restenosis(17.6%vs 0) and target vessel revascularization(17.6%vs 0)(P

Objective To determine the long-term outcomes of renal interventional therapy in patients with renal artery stenosis. Methods One hundred thirty-four consecutive patients reveived renal stenting in our hospital. The changes of BP and serum creatitine were measured 24 hours after the procedure and during the first and second year of follow-up. Results All procedures were performed successfully. The mean serum creatitine level increased [(109.8?24.6) ?mol/L vs (99.4?27.8 baseline level) ?mol/L] and the glomerular filtration rate decreased [(57.6?19.3)mL/min vs (68.5?18.9) mL/min] significantly after the procedure. However during the first and second year of follow-up, the serum creatitine level returned to the pre-procedure level. Sixty-four patients attained benefit of BP improvement at about 6 months after renal artery stenting. The mean systolic pressure 6 months after the procedure was (148.6?22.6) mm?Hg (1 mm?Hg=0.133 kPa), which was significantly lower than the baseline level. During the first and second year of follow-up, there were 56 patients (50.6%) and 50 patients (49.6%) achieved BP improvement from renal stenting respectively. Conclusion Renal stenting is efficient and has satisfactory long-term outcomes in treating renal artery stenosis.

Objective The aim of this study was to assess the clinical value of pro-gastrin releasing peptide (ProGRP) , squamous cell carcinoma antigen (SCC-Ag), cytokeratin 19 fragment antigen 21-1 (Cyfra21-1) and carcino-embryonic antigen (CEA) in the diagnosis and clinical stage of lung cancer in Chinese patients.Methods Patients with lung cancer and benign lesions confirmed by pathology were enrolled in Peking Union Medical College Hospital from January 2013 to October 2014.The serum levels of four tumor markers (ProGRP, SCC-Ag, Cyfra21-1 and CEA) were measured using immunoassays before treatment.The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and the areas under the receiver operating characteristic curve (AUCROC) of these four tumor biomarkers were analyzed for the diagnosis of lung cancer.Results A total of 134 patients were finally analyzed, including 73 patients with lung cancer and the other 61 patients with benign lung disease.The diagnostic sensitivity of serum Cyfra21-1 to lung cancer was 67.1％, the specificity 45.1％, the AUCROC 0.658.The diagnostic sensitivity of the panel including ProGPR, Cyfra21-1 and CEA to lung cancer was 75.3％ , the specificity 57.4％ , the AUCROC 0.702.In the lung cancer group, the AUCROC of ProGRP over 65 ng/L to diagnose small cell lung cancer was 0.954;the AUCROC of SCC-Ag over 1.5 μg/L to diagnose squamous cell lung cancer was 0.788;the AUCROC of Cyfra21-1 to diagnose non-squamous-non-small-cell lung cancer was 0.716.In small cell lung cancer patients, the level of ProGRP in limited-disease small cell lung cancer (LD-SCLC) were significantly higher than that in extensive-disease small cell lung cancer (ED-SCLC) (P =0.005).Conclusion This panel of serum tumor markers including ProGRP, Cyfra21-1 and CEA improves the diagnostic specificity and sensitivity in patients with high-risk lung cancer.The serum CEA level of advanced lung cancer patients is significantly increased.The high level of serum ProGRP predicts the ED-SCLC.

Objective To investigate the preventive effects of anti-viral therapy in combination with transcatheter arteria chemoembolization (TACE) on recurrence of HBV-related hepatocellular carcinoma (HCC) after operation. Methods According to selection standards, 49 patients treated in this hospital from January 2003 to June 2009 were enrolled in this study and divided into a control group and combined group.The cumulative tumor-free survival rate, cumulative survival rate, the 1-, 2- and 3-year recurrence rates and cumulative recurrence rates were determined in all the patients and compared between the 2 groups. Results The cumulative tumor-free survival rate and cumulative survival rate were significantly higher in the combined group than in the control group (P=0. 019, 0. 008). The 1-, 2-, and 3-recurrence rates were 24% vs. 38.9%, 28% vs. 33.3%, and 28% vs. 22.2% in the combined group and control group, respectively. The 1-, 2-, and 3-year cumulative recurrence rates were 24% vs. 38. 9%, 52% vs. 72. 2%, and 80% vs.94. 4% in the combined group and control group, respectively. Conclusion Anti-viral therapy in combination with TACE can exert significant preventive effects on recurrence of HBV-related HCC after operation.

Objective To investigate the characteristic of surgical treatment of burns in pediatrics patients. Methods From January 2006 to March 2012,47 pediatrics patients and 244 adult patients were received the surgical treatment in our hospital. The clinical data of two groups were analyzed retrospectively and compared. Results The female ratio in pediatric patients was higher than adult group,and almost patients received operation,especially plastic surgery and skin repair,with less surgeries of wound repair and infected surgeries. The preopera-tive physiological index between two groups was no significantly different. Conclusion On the premise of effective preoperative preparation, we could carry out surgical treatment of burns for pediatrics patients positively.
