Objective:To analyze and evaluate the usage and tendency of quinolones before and after the special rectification of antibacterial in one grade III level A hospital in üanjing to provide evidence for the special rectification of antibacterial and manage-ment. Methods:The usage records of quinolones in 2010( before the special rectification)and in 2011-2013( after the special rectifi-cation)were collected,and the sales revenue,DDDs,defined daily cost( DDC),drug resistance and adverse drug reactions( ADR) were analyzed retrospectively. Results:Both the amount and ratio of the sales revenue of quinolones were declined dramatically after the rectification(2011-2013). Among all kinds of quinolones,the sales revenue and DDDs of lomefloxacin aspartate injections was the highest before the rectification while moxifloxacin injections and levofloxacine hydrochloride injections ranked the first and the second respectively in sales revenue after the rectification(2012-2013). As for the DDDs,levofloxacin hydrochloride tablets and levofloxacine hydrochloride injections were the highest after the rectification. Besides,moxifloxacin injections had the highest DDC after the rectifica-tion. Moreover,the drug resistance of the main drug-resistant bacteria( namely staphylococcus,enterobacteriaceae and non fermenta-tion bacteria)to levofloxacin,norfloxacin and ciprofloxacin was declined after the rectification. The adverse drug reactions of levofloxa-cin,lomefloxacin,enoxacin and moxifloxacin were declined year by year after the rectification,and the ADR ratio of quinolones in all anti-bacterial agents was also declined. Conclusion:After the special rectification of antibacterials,the hospital exhibits obvious im-provement in all the application indices of antibacterials,reflecting a good result of the special rectification. However,the hospital still needs to strengthen the inspection over the clinical application of the fourth generation of quinolones.

Objective To analyze the predictive value of platelet related indicators for patent ductus arteriosus (PDA) in extremely low birth weight infants (ELBW). Methods The data of 79 ELBW infants born from June 2013 to June 2016 were retrospective analyzed. There were 48 cases without PDA (nPDA group) and 31 cases with PDA (PDA group). Among 31 cases with PDA, there were 17 cases of non-haemodynamically significant PDA (nhsPDA group) and 14 cases of haemodynamically significant PDA (hsPDA group). The clinical feature and platelet related indicators among nPDA group, PDA group, nhsPDA group and hsPDA group were compared. Multivariate logistic regression was used to analyze the effects of various factors on the occurrence of PDA. ROC curve analysis was performed to evaluate the early predictive value of platelet related indicators for PDA. Results Compared with the nPDA group, the PDA group had a smaller gestational age, a higher proportion of male infants, and a smaller platelet distribution width (PDW), and there were statistically significant differences in all of those (P all<0.05). Multivariate logistic regression analysis indicated that the risk of PDA was increased as the PDW was decreased (OR=1.26, 95%CI: 1.05~1.52). The ROC curve analysis showed that the best diagnostic value of PDW was 13.4 GSD, and the sensitivity of early prediction of PDA was about 67.74%, and the specificity was 68.75%. Compared with nhsPDA group, hsPDA group had a smaller gestation age, lower cesarean section rate, and there were statistically significant differences (P all<0.05). There was no significant difference in platelet related indicators between hsPDA group and nhsPDA group (P>0.05). Conclusion PDW has certain early predictive value for PDA in ELBW. ELBW infants with PDW<13.4 GSD need to be watched closely for the occurrence of PDA.

OBJECTIVE:To focus on the phenomenon of medication socialization.METHODS:Referenced by the related literature,different social factors affecting medication socialization were analyzed from the perspective of social pharmacy.RESULTS&CONCLUSION:The social factors affecting medication socialization were patients,pharmaceutical enterprises,governmental regulatory agencies,pharmacologists,new technologies,hospitals,doctors etc.To prevent medication from over-socialization effectively,medical professionals’roles should be brought into full play,people’s consciousness of rational drug use should be strengthened,enterprises’attention to the social effects should be emphasized,and governmental supervi-sion should be strengthened,meanwhile correct public opinion orientations should be followed.

To explore the effect of magnitude and duration on the performance of Cumulative Sum (CUSUM),with simulation method used on the subject after the insertion of 11 outbreak events into baseline data with Poisson distribution.Sensitivity fluctuated from 9.1％ to 100.0％ with specificities higher than 98.6％.Sensitivity was significantly correlated with magnitude,and increased along with the increase of magnitude.However,no significant correlation was observed between sensitivity and duration.A magnitude which was at least 2.6 times higher than that of the mean daily baseline could result in the sensitivity of 100.0％.Time-lag would be improved along with the increase of magnitude.Time between onset and detection of an outbreak was no longer than one day when magnitude was more than 1.8 of the mean daily baseline.In summary,the performance of CUSUM was influenced by magnitude,but not by duration.CUSUM had the advantage of good time-lag and high sensitivity when the outbreak magnitude was more than 2.4 time over the baseline data.

Objective： This study was designed to evaluate the clinical experience of esophageal replacement with colon (ERC). Methods： Among 51 patients, 6 with benign stricture and 45 with esophageal carcinoma, all of them were performed cervical esophagocologastrostomy. Among 51 patients, 48 patients received ERC by the transverse colon, including isoperistaltic anastomosis (27/48) and antiperistaltic anastomosis (21/48); three patients received ERC along the peristaltic direction by the right-side colon. In these patients, 24 cases were supplied blood by the arteria colica media and 27 cases by the arteria colica sinistra. Results： There was no operative death in the whole group. The postoperative complications consisted of leakage of cervical anastomosis(2 cases), cervical wound inflammation(3 cases), laryngeal recurrent nerve injury (1 cases), lung inflammation (3 cases). Conclusion： The authors conclude that colon was rich in blood and enough in length so that it can be grafted into neck and anastomosed with the esophagus and the result is satisfactory. Improved surgical technique can reduce the incidence of complications of ERC.

Though parched Chinese herbal medicines contain less effective or index components, their pharmacological actions do not reduce or even become improved to some extent. However, the current studies related to material basis could not explain the changes in property, flavour and efficacy of parched Chinese herbal medicines. Meanwhile, due to the lack of objective and specific evaluation indexes, the quality evaluation could not reflect features of parched Chinese herbal pieces. Therefore, how to break the bottleneck for the studies on parched Chinese herbal pieces, make further innovation and conduct in-depth studies on the material basis of parched Chinese herbal medicines are common problems that medical scholars are facing. According to the findings in the previous studies, the author proposed to explain the material basis of parched Chinese herbal medicines by studying Maillard reaction and establish specific quality evaluation indexes according to the features of parched Chinese herbal pieces, and conducted relevant studies.

The L-ATC hydrolase and L-SCC amidohydrolase which convert L-ATC to L-cysteine in Pseudomonas sp.TS-1138 are purified about 83.9 and 90.3 fold by salting-out method, Sephadex G-75 gel chromatography, DEAE-cellulose 52 ion exchange and Sephadex G-100 gel chromatography, etc. The purified enzyemes are both demonstrated by SDS-PAGE to be a homogeneous protein. Their molecular weight are about 37.5kD and42.8kDa respectively. The optimum reaction temperature are both 35℃, and the optimum pH are 7.0 and 8.0 respectively. The Km of the two enzymes are 0.67 mmol/L and 0.15 mmol/L, and the Vmax are 0.39?10 -3mmol/L?min and 0.42?10 -3mmol/L?min respectively.

The interaction between Gliotoxin and bovine serum albumin (BSA) was studied by the fluo-rescence, Circular Dichroism (CD) and ultraviolet visible (UV-Vis) techniques. The fluorescent experiment showed that the intrinsic fluorescence of BSA was quenched by the binding of gliotoxin in a static quenching procedure, with an association constant of 7.2?103 L/mol and in hydropobic forces. And the CD spectrum revealed that gliotoxin effected the conformation of BSA by increased the mass of ?-helix.
