Objective: To assess the value of transesophageal echocardiography (TEE) during cardiac surgery. Method: Intraoperative TEE was performed to record left atrial gas during and for 15 minutes after bypass in 131 pa tients and to evaluate mitral regurgitation after mitral replacement in 38 patients. The degrees of the gas and mitral re gurgitation by TEE was visually quantified on a 4-point scale(0 to 3) and a 5-point scale(0 to 4), respectively. Result: The left atrial gas was detected in 115(88%)patients, two of which with positive echograms(gas grade=3). There was significant improvement in the mean mitral regurgitation grade after mitral replacement (3.4?0.6 to 0.5?0.2, P

Objective To explore the effect of different method in preventing broncho-pulmonary dysplasia(BPD) in very low birth weight infants(VLBWI) during mechanical ventilation.Methods The gestational age of 71 infants with VLBWI was (30?2) weeks and the average weight was (1235.2?160.6)g.The infants were randomly divided into three groups,they received different therapeutic regimens during mechanical ventilation:32 cases were treated with permissive hypercapnia(PHC) ventilation in group Ⅰ;20 cases were treated by intratracheal instillation of pulmonary surfactant(PS) in group Ⅱ;19 cases were treated by inhalation of becotide(beclomethasone dipropionate,BDP) in group Ⅲ.The ventilator settings,blood gas analysis,clinical symptoms and therapeutic effect were statistically analyzed and compared.Results The peak inspiratory pressure(PIP) and ventilation rate(VR) of ventilator parameter were (18.3?1.6)cmH_2O and (35?5)bpm in group Ⅰ,there was significantly lower than that in group Ⅱ and group Ⅲ(P0.05).The incidence of BPD was 16%(5/32) in group Ⅰ,5%(1/20) in group Ⅱ and 5%(1/19) in group Ⅲ;The mortality rate of PHC group(group Ⅰ) was 6%(2/32) and 5%(1/20) in group Ⅱ.Conclusion The application of permissive hypercapnia,intracheal instillation of pumlonary surfactant and inhalation of becotide all can prevent effectively the occurrence of severe broncho-pulmonary dysplasia in VLBWI during mechanical ventilation.

Stenotrophomonas maltophilia is among eight strain of broad resistance to antibacterial. It has been pay attention to global students, and is very difficulty in clinic treatment. Infection of Stenotrophomonas maltophilia is more familiar in ICU. Its test rate is 13.45%(62/461) in the study .The resistance character: IPM﹑CZO﹑CRO﹑AMP and MNO is highest(resistive rate 100%). ATM、GEN 、 KAN 、MEM 、CTX and PIP is much high(≧86.5%), LVX﹑GAT and FEP is high (=50%).Conclusion: Stenotrophomonas maltophilia should be monitored in the hospital. Used of antibacterial must be rational. Severe disinfection and isolation should been put in practice to the infected patients. CSL is very active antibacterial (active rate 90.6%) against Stenotrophomonas maltophilia in the study, and ought be selected headmost in treated its infection.

Objective:To establish a test method for histamine-like substances in aclarubicin hydrochloride. Methods:According to the method in the appendix of Chinese Pharmacopoeia ( edition 2010 ) , the test of histamine-like substances was carried out. Re-sults:The test of histamine-like substances was not interfered by aclarubicin hydrochloride with the concentration below 0. 01 mg· ml-1 . Histamine-like substances in 4 batches of samples were determined by the established method, and the results were consistent with those of the test method for depressor substances. Conclusion: The test method for histamine-like substances is feasible with the limit of 1 μg·mg-1 .

Objective:To establish the test method for histamine-like substances in pirarubicin. Methods:According to the meth-od described in the appendix of Chinese Pharmacopoeia (2010 edition), the test for histamine-like substances was carried out. Re-sults:The test for histamine-like substances had no interference under the condition with pirarubicin concentration of 0. 01mg·ml-1 . The established test method for histamine-like substances in pirarubicin was applied in 10 samples, and the results were accordant with those of the test method for depressor substances. Conclusion:The test method for histamine-like substances in pirarubicin is feasible with the limit of 1 μg·mg-1 .

To establish an HPLC-MS/MS method for the analysis of quercetin, kaempferid and isorhamnetin in rats plasma and study its pharmamacokinetics after an intragastrical administration of Hippophae rhamnoides extracts. Five healthy male Sprague-Dawley (SD) rats were given single doses of H. rhamnoides extracts (quercetin 26.35 mg x kg(-1), kaempferid 4.040 mg x kg(-1), isorhamnetin 31.37 mg x kg(-1)), and then their orbital sinus blood samples were collected at different time points. The drug plasma concentration of the three flavonoids was determined by HPLC-MS/MS method. After that, the main pharmacokinetics parameters were calculated by using Kinetica 5. 0. 11 software. The methodological test showed that the linear concentration ranges of quercetin, kaempferid and isorhamnetin were 7.500-600.0 μg x L(-1) (R2 = 0.998 5), 1.000-80.00 μg x L(-1) (R2 = 0.998 5 ) and 10.00-800.0 μg x L(-1) (R2 = 0.998 0), respectively. The inner and inter-days precisions were both less than 14.0%. The plasma samples showed a good stability and consistency with the requirement of biological sample analysis after the samples were frozen once and placed at - 20 degrees C for 15 d and room temperature for 6 h and the treated analytes were placed at -20 degrees C for 24 h. For quercetin, the pharmacokinetic parameter t(½β), AUC(0-∞), MRT(0.∞), C.(max) and T(max) were (113.3 ± 19.37) min, (12 542.14 ± 3 504.05) μg x h x L(-1), (119.6 ± 13.29) h, (164.6 ± 27.33) μg x L(-1) and (5.199 ± 0.840 3) h, respectively. For kaempferid, the pharmacokinetic parameters t(½β), AUC(0-t), MRT(0-∞), C(max) and T(max) were (79.85 ± 17.15) min, (934.51 ± 94.59) μg x h x L(-1), (81.50 ± 13.75) h, (80.15 ± 14.24) μg x L(-1) and (3.827 ± 0.902 7) h, respectively. For isorhamnetin, the pharmacokinetic parameters t1,2,, AUC(0-t), MRT(0-∞), C(max) and T(max) were (118.3 ± 20.73) min, (26 067.77 ± 4 124.60) μg x h x L(-1), (129.0 ± 16.30) h, (269.6 ± 29.32) μg x L(-1) and (6.513 ± 1.450) h, respectively. The HPLC-MS/MS analysis method established in this study was proved to be sensitive and accurate and could be applied in the pharmacokinetic study of quercetin, kaempferid and isorhamnetin in rat plasma.

OBJECTIVE:To explore the similarity of dissolution profiles of self-development and original preparation of Solife-nacin succinate tablet,and provide reference for the prescription and process screening of the former one and the quality similarity evaluation of the latter one. METHODS:The paddle method was adopted with rotational speed of 50 r/min,using water,pH1.2 hy-drochloric acid solution,pH4.0 acetate buffer solution and pH6.8 phosphate buffer solution as dissolution media,HPLC was used to determine the cumulative dissolution of main components of self-development and original preparation of Solifenacin succinate tablet at different time points,dissolution profile was drew,then f2 was used to evaluate its similarity. RESULTS:In the 4 dissolu-tion media,the f2 of both self-development and original preparation of Solifenacin succinate tablet was higher than 50,which indi-cated that the dissolution profiles showed similarity. CONCLUSIONS:The established HPLC is suitable for the dissolution determi-nation of Solifenacin succinate tablet;the dissolution profiles of the self-development and original preparations are basically simi-lar,which indicates the prescription and technology of self-development preparation are feasible.
