Objective To investigate the therapy efficiency and complication prevention in patients undergoing radiofrequency current catheter ablation combined with multiple X-ray projecting angles.Methods Two hundred and six atrioventricular nodal reentrant tachycardia (AVNRT) patients were involved in this study. The distance between the tip of His and the ostium of coronary sinus were measured under different X-ray projecting angles respectively, including posterior anterior (PA), right anterior oblique 30° (RAO 30° ) and left anterior oblique 45° (LAO 45° ) in each patient, and mapping was proceeding under the corresponding X-ray projecting angles with the longest distance. The distance between ablating catheter and His was confirmed again before powering by the other two X-ray projecting angles. Results The longest distance between the tip of His and the ostium of coronary sinus were obtained in 66,75 and 65 patients under PA,RAO 30° and LAO 45° respectively(P＞ 0.05 ),and the data were (2.94 ± 0.87), (2.98 ± 0.76)and (2.91 ± 0.52) cm(P＞ 0.05). Transient first or second degree of atrioventricular blocking was observed in 4 cases among 22 high risk patients in which the powering sites were above the medium level of the distance between the tip of His and the ostium of coronary sinus under three kinds of X-ray projecting angles obviously.However,only 1 case was observed in other 184 patients(P＜ 0.01 ). All patients were cured successfully and no permanent atrioventricular blocking occurred. Conclusion Radiofrequency current catheter ablation combined with multiple X-ray projecting angles is helpful to increasing the successful rate and preventing complication in ablating therapy.

Objective To investigate the molecular mechanism of Klebsiella pneumoniae resistant to carbapenem. Methods The minimal inhibitory concentrations ( MICs) of the antimicrobial agents were determined by E-test. The 23 β-lactamase genes and 2 porin genes were amplified by polymerase chain reaction (PCR) , then the products were purified and their sequences were analyzed. Results The MICs of piperacillin, piperacillin/sulbactam, amoxicillin/clavulanic acid, cefoperazone/sulbactam, cefotaxime, cefepime and aztreonam to 5 strains of Klebsiella pneumoniae were all higher than 128 μg/mL, and those of imipenem or meropenem were higher than 32 μg/mL. All isolates carried blaTEM-1 and blaDHA-1 genes. Deletion of ompK35 and ompK36 were observed in Kp01 and Kp03, and the deletion of ompK35 was also observed in Kp02 and Kp05. Base insertion of ompK36 occurred in Kp02, Kp04 and Kp05. Compared with GenBank (GU945384) , ompK35 gene mutations of G→C at base 465 and T → C at base 466 in Kp04 lead to Gln to His substitution at position 155 and Tyr to its substitution at position 156, and it might be a new subtype. Conclusion The production of DHA-1 β-lactamase combined with the loss of OmpK36 or OmpK35 in porin genes may contribute to high-level carbapenem resistance in Klebsiella pneumoniae.

Objective The aim of this study is to identify association between increased serum activity of alanine aminotransferase (ALT) and metabolic parameters in non-alcoholic population of north China. Methods A total of 5351 subjects who came to visit Yuquan Hospital of Tsinghua University for health examinations during May to December 2007 were divided into two groups based on their serum ALT activities, one with equal to or more than 40 U/L and the other with less than 40. Anthropometric data, blood pressure, serum ALT, serum levels of triglyceride (TG), total cholesterol (TC), high-dense lipoprotein-cholesterol (HDL-C), low-dense lipoprotein-cbolesterol (LDL-C) and fasting blood glucose (FBG) were measured for all of them. Results Body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), TG, TC, HDL-C, LDL-C and FBG were significantly different between the two groups. BMI, TG, TC, HDL-C, LDL-C and FBG all associated with increased ALT both in males and females. DBP associated with increased ALT in males and SBP with it in females, logistic regression analysis showed that male, younger age, raised BMI, TG, TC, FBG and reduced HDL-C were strongly associated with increased serum ALT. Conclusions Results showed that metabolic disturbance such as obesity, hypertension, dyalipidemia, hyperglycemia, and so on associated with increased ALT in non-alcoholic population of north China.

OBJECTIVETo investigate the risk of hidden blood loss about applying rivaroxaban after total hip arthroplasty.

METHODSFrom October 2009 to May 2012,88 patients with femoral head necrosis were treated with primary total hip arthroplasty. All the patients were divided into Rivaroxaban group(44 cases)and control group(44 cases). There were 25 males and 19 females in the Rivaroxaban group, with an average age of (58.48 +/- 15.19) years old; in the control group,24 patients were male and 20 patients were female, with an average age of (61.11 +/- 13.54) years old. The patients in the Rivaroxaban group took Rivaroxaban orally from the first day after operation with a dose of 10 mg each day, and treatment course was 14 days. The patients in the control group took placebo orally at the same time. Dominant blood loss and transfusion were recorded, blood routine examinations were taken before operation and at 3 days after operation. The total blood loss and hidden blood loss were calculated according to the formula.

RESULTSThe mean total blood loss was (1509.56 +/- 325.23) ml and the hidden blood loss was(581.47 +/- 215.01) ml, accounting for (37.88 +/- 10.42)% in the Rivaroxaban group. The mean total blood loss was (1262.30 +/- 397.95) ml and the hidden blood loss was (395.59 +/- 97.33) ml, accounting for (30.62 +/- 0.20)% in the control group. The total blood loss, hidden blood loss and transfusion in the Rivaroxaban group was significantly more than those in control group,b ut there was no significant difference on dominant blood loss between two groups.

CONCLUSIONRivaroxaban increased the overall bleeding risk of total hip arthroplasty, especially hidden bleeding risk, which should be careful used.
