OBJECTIVE:To explore the general patterns and characteristics of the adverse drug reactions(ADR)induced by acyclovir.METHODS:52 acyclovir-induced ADR reports(60 cases)published in China Hospital Knowledge Database from 1994 to 2006 was analyzed statistically.RESULTS:The ADR induced by acyclovir were more often occurred in patietns aged from 31 to 60,with 41.67% appearing within 10～60 min after drug use.The clinical presentation was complex and diverse,which involved different systems and organs,predominantly the lesion of renal function.CONCLUSION:Clinician and pharmacists should attach great importance to Acyclovir-induced ADR in clinical practice and stick to rational drug use.

This study aimed at developing an ultra-performance liquid chromatography electrospray time of flight-mass spectrometry (UPLC-ESI-QTOF-MS) method for the identification of bovine hide gelatine from the shell glue of the red-eared slider.Tortoise shell glue was made from the shell of red-eared slider or Reeves' turtle (Chinemys reevesii).The samples were analyzed on UPLC-ESI-QTOF-MS after being digested by trypsin,and the ions at m/z 604.8,m/z 641.3,m/z 790.8 of the marker peptides of bovine hide gelatin were detected.As a result,it was found that the test results of the ions made from the shell of red-eared slider at m/z 641.3 were positive,taking the same fragmentation regularity of MS/MS as the standard of bovine-hide gelatine,while negative results were detected from the ions made from the shell of Reeves' turtle.In conclusion,the method was simple and accurate provided a basis for distinguishing the tortoise shell glue from bovine hide,which could be also used for the quality control of tortoise shell glue.

Objective To evaluate the causation and management of complications caused by enteral nutrition (EN)after stomach cancer surgery.Methods The clinical data of 195 gastric cancer patients which used EN after surgery were analyzed retrospectively from September 2002 to April 2008 in our hospital.Results Among the 195 patients,29(14.87%)developed abdominal distention,17(8.71%)diarrhoea,Six(3.07%)metabolic complica tions,three anastomotie leakage,1 patient with colon perforation.Conclusion These complications caused by EN after stomach cancer surgery associated with the stress of surgery,the speed and concentration of nutrition infusion, patients'metabolic conditions and other related factors.

This study aimed at identifying pig-hide gelatin from tortoise shell glue using ultra-performance liquid chromatography-electrospray-time of flight mass spectrometry(UPLC-ESI-QTOF-MS/MS).The samples of tortoise shell glue were digested by trypsin before the analysis on UPLC coupled with QTOF mass spectrometry.The ions at m/z 925.4 were selected as the marker peptides of pig-hide gelatin.It was found that the test results of the ions at m/z 925.4 were positive in the samples with low contents of the marker peptides of tortoise shell glue,indicating the existence of pig-hide gelatin.However,the result of bovine-hide gelatinordonkey-hide gelatin was negative,while negative results were detected in tortoiseglue standard.The finding was in conformity with previous references over the fragmentation regularity of MS/MS.In conclusion,the method can be adopted to identifying the pig-hide gelatin from tortoise shell glue and applied to the quality control of tortoise shell glue with high specificity and sensibility.

Objective To investigate the effect of Shenxiong glucose injection on platelet reactivity during aspirin treatment in patients with acute ischemic stroke.Methods A total of 263 patients with acute ischemic stroke admitted to 12 hospitals from January 2014 to December 2016 were enrolled prospectively.They were randomly divided into aspirin group and aspirin + Shenxiong glucose injection group.The changes of platelet maximum aggregation rate induced by 4 platelet aggregating agents (arachidonic acid,adenosine diphosphate,collagen and platelet activating factor) were detected before and after the treatment.Results There were no significant differences in the demographic data and baseline clinical characteristics between the aspirin group (n =132) and the Shenxiong glucose injection + aspirin group (n =131).At baseline,the maximum aggregation rate of platelet induced by arachidonic acid and platelet activating factor in Shenxiong glucose injection + aspirin group was significantly higher than that in the aspirin group (all P ＜0.05).On the 6th day after treatment,the maximum aggregation rate of platelets induced by the 4 aggregating agents in the Shenxiong glucose injection + aspirin group was significantly lower than that in the aspirin group (all P ＜ 0.001).Conclusion Shenxiong glucose injection had a significant inhibitory effect on platelet reactivity during aspkin treatment in patients with acute ischemic stroke.

Objective To find frontal lobe-amygdala functional connections in different age paragraph female patients with bipolar disorder. Methods The FMRI date were acquired from 30 patients with bipolar disorder aged 13 to 25 years old and 30 age-and education level-and gender-matched health controls.FMRI was also conducted on 30 patients with bipolar disorder aged 26 to 45 years old and 30 age-and education level-and gender-matched health controls.The date was calculated by using MATLAB based DPARSF software. Results Compared with corresponding health controls, the lobe-amygdala functional connections significantly decreased in patients aged 13 to 25 years but remained unchanged in patients aged 26 to 45 years old. Conclusions The decrease in the frontal lobe-amygdala functional connections decreased in female patients aged 13 to 25 years old may be related to the underdevelopment in vulnerable immature brain.In contrast, the frontal lobe-amygdala functional connections in female patients aged 26 to 45 years old remain intact.
