Objective To summarize the treatment experience of supraventricular tachycardia (SVT) after coronary artery bypass graft (CABG). Methods The clinical data of 136 patients who had occurred SVT after CABG between January 2008 and December 2009 were analyzed retrospectively. Results Among 136 patients,no perioperative mortality,atrial fibrillation (AF) occurred in 110 cases (80.88%),paroxysmal supraventricular tachycardia (PSVT) occurred in18 cases ( 13.24% ), atrial flutter occurred in 8 cases (5.88%),112 of 136 cases occurred in 1-3 days after surgery,accounting for 82.35% ,24 cases occurred in 4-7 days after surgery,accounting for 17.65%. Given amiodarone in the treatment of 105 cases,100 cases reverted to sinus rhythm (cardioversion rate of 95.24% ),given esmolol in the treatment of 11 cases, 9 cases reverted to sinus rhythm( cardioversion rate of 81.82% ), synchronous direct current cardioversion in 20 cases, all transferred to sinus rhythm, all patients with improved symptoms. The remaining failed to transfer to sinus rhythm, had got normal ventricular rate, and symptoms improved significantly. Conclusions It is necessary to take effective measures to prevent SVT within 3 days after CABG. Amiodarone, esmolol and synchronous direct current cardioversion can be used effectively and safely to control SVT after CABG.

To establish the proliferation and apoptosis index(P/AI), and to explore its relationship to the malignant degree of gliomas. Specimens of normal brain tissues obtained from 8 patients undergoing decompression operation for head injury, and 69 paraffin-embedded specimens and 26 fresh specimens of the glioma were studied. Immunohistochemical staining of proliferation cell nuclear antigen (PCNA) and terminal deoxynucleotidyl transferase mediated dUTP DIG nick end labeling(TUNEL) were used to determine the proliferation and apoptosis rates of the glioma. Grading was defined by the ratio between PCNA positive rate and TUNEL positive rate (P/AI). An increase in P/AI denoted an increase in malignancy. It was found that P/AI of normal brain tissue was 0.2-1.5. In 85.1% of grades Ⅰ and Ⅱ gliomas, P/AI was lower than 2.5 and while in 91.7% of grades Ⅲ and Ⅳ gliomas P/AI was 2.5. There were significant differences between normal group, grades Ⅰ and Ⅱ and grades Ⅲ and Ⅳ over gliomas (P

Objective To investigate the predictive value of red cell volume distribution width RDW),RDW to platelet ratio (RPR),aspartate aminotransferase (AST) to platelet ratio index APRI),fibrosis index based on the 4 factor (FIB-4) and aspartate-alanine aminotransferase ratio (AAR) in assessing esophageal varices (EV) in patients with hepatitis B virus (HBV)-related cirrhosis.Methods Between December 2013 and July 2015,a total of 190 patients with HBV-related cirrhosis and no previous history of endoscopic therapy for EV hospitalized at the Department of Hepatology,Tianjin Third Central Hospital were enrolled.Upper gastrointestinal endoscopy were conducted in all patients to diagnose EV.According to the morphology and degree of EV as well as bleeding risk,patients were categorized into mild,moderate and severe stages.RDW,platelet counts,alanine aminotransferase,aspartate aminotransferase were tested,and RPR,APRI,FIB-4,AAR were calculated.Spearman correlation was used to evaluate the association between EV and these indexes.Receive operating characteristic (ROC) curves were generated and the areas under the curves (AUC) were calculated to assess the performance of these indexes in predicting esophageal varices bleeding (EVB).Results RDW ([16.78±2.27]％),RPR (0.41±0.18),FIB4 (8.99±5.91),APRI (2.09[1.35,2.90]) in patients with EVB were all significantly higher than those ([14.37±1.86]％,t=-7.449;0.19±0.09 [t=-8.132];5.72±3.92 [t=-3.658];1.29 [0.70,2.39;z=-2.996]) without EVB (all P＜0.05).However,AAR had no statistical significance between two groups (t =1.216,P=0.226).Both of EV and EVB had positive correlation with RDW,RPR,FIB-4 and APRI (all P＜0.05) and no correlation withAAR(P＞0.05).RDW (F=9.604),RPR (F=47.530),FIB-4 (F=18.071) and APRI (H=12.320) showed statistically significant differences among patients with different stages of EV (all P＜0.05),whereas AAR showed no difference (F=1.177,P=0.320).The AUC of RPR (0.896) for EVB was highest,followed by RDW (0.824,P＜0.05).AUC of FIB-4 and APRI was 0.690 and 0.642,respectively,with no statistical difference (P＞0.05).The optimal cut-off levels of RDW,RPR,FIB-4 and APRI were 14.450 (sensitivity:88.24％,specificity:64.03％),0.209 (sensitivity:96.10％,specificity:69.10％),6.912 (sensitivity:66.67％,specificity:73.38％) and 1.338 (sensitivity:76.47％,specificity:51.08％),respectively.Conclusions RPR and RDW are closely correlated with EV in HBV-related cirrhotic patients,which are of clinical importance in predicting EVB.Both of them can be used as clinical screening methods and RPR may be superior to RDW.Although FIB-4 and APRI are correlated with EV,their predictive value of EBV are low.

Aim: To establish a method for the determination of pantoprazole sodium and its related substances. Methods: A column packed with octadecylsiance bonded silica gel (250 mm × 4. 6 mm, 5 pjn) was used. The 0. 01 mol/L monopotassium phosphate solution( adjusted with phosphoric acid to pH 7. 0) -acetonitrile were adopted as the mobile phase, a gradient elution was programmed as follows: 0→30 min(90:10-60:40), 30→45 min(60: 40→15: 85); the detection wavelength was 289 nm; the column temperature was 40 ℃; the flow rate was 1. 0 mL/min. Results: Pantoprazole sodium, the intermediates and its related substances could be well separated. A good linear relationship was obtained over the range of 6. 96-48. 72 μg/mL( r =0. 999 9). The limit detection and quantisation of pantoprazole sodium were 8.51 ng and 17.0 ng, respectively. Conclusion: This method can be applied to control the related substances of pantoprazole sodium and determine pantoprazole sodi-um.

Objective To explore the occurrence, clinical feature and the associatrd factors of Sjogren' s syndrome(SS) complicated with Idiopathic Pulmonary Fibrosis(IPF) to build up knowledge for early diagnosis. Methods The clinical characteristics of 160 cases damitted SS patients collected from January 2002 to August 2008 were retrospectively investigated including RF, chest - X, ESR, blood -gas analysis,pulmonary function tests,chest HRCT,ANA and so on. Results The patients with IPF accounted for 33.12% of total SS patients, including 12 cases of male. These patients presented strongly positive ANA,strongly positive RF etc,especially in the male. Conclusion The occurrence of SS - IP was related to the disease' s activity. FHRCT and pulmonary function test should taken early in order to get early diagnosis and treatment.

Objective To study the expression of lectin-like oxidized LDL receptor-1 (LOX-1) protein in acute lung injury (ALI) and the effect of captopril on this expression in order to investigate its role in the process and preliminary intervention.Methods Sprague-Dawley rats were randomly divided into 3 groups,normal control group,lipopolysaccharide (LPS) groups,and a LPS+captopril group,each group 10 rats.ALI model was induced by intratracheal injection of LPS (5 mg/kg),then those of LPS+captopril group were give an intraperitoneal injection of captopril (1.25 mg/kg).The animals of normal control group received an intratracheal injection of normal saline.In 6 h after LPS injection,the level of p(O2),wet/dry ratio (W/D),concentration of total protein in bronchoalveolar lavage fluid (BALF) and lung tissue histopathological changes were examined.The expression of LOX-1 protein in the lung tissue was measured by Western blot analysis.HE staining was used to examine the pathological changes of the lung.Results Histological examination showed that extensive lung inflammation were seen in the LPS group,which manifested by accumulation of significant numbers of neutrophils.The level of p(O2) in LPS group [(6.86?0.75) kPa] was decreased compared with that in sham group [(12.14?0.60) kPa,P

To evaluate the curative effect of antisense telomerase ODN on malignant glioma cells. The activity of telomerase in 16 fresh malignant gliomas was detected positive by PCR ELISA method. After covered with lipofectin, the 5?mol/L telomerase ODN was incubated with cultured gliomas cells. PCNA, TUNEL positive rate and the phase of cell cycle were detected by FcM per 24h. The results showed: Anti sense ODN inhibited telomerase activity after being applied for 48 hours, and inhibition was complete at 72 hours, The ODN inhibited proliferation of malignant gliomas and promoted their apoptosis markedly at 72 hours. After 96 hours, most transfected glioma cells were stopped to grow at G 2/M phase, and the number of apoptosis cells increased as time went on. The results suggested that anti sense telomerase ODN could inhibit the telomerase activity, and in turn promote aptoptosis of glioma cells and inhibit the growth of the tumor.

Pharmaceutical excipients are implementing registration and approval management in our country. As the disadvantages of the registration system appearing continuously, the demand for reform is getting higher and higher. The cry for drug master files ( DMF) model instead of registration and approval management is becoming more prominent. Based on the understanding of DMF sys-tem, the article discussed the positive roles of the excipients standards and guidelines construction in DMF implementation using phar-maceutical excipients supervision experience in the United States as the reference and starting from the standards and guidelines system of excipients, which aimed to provide suggestions for the supervision and management of pharmaceutical excipients, and improve the quality and safety of pharmaceutical excipients and drugs.
