Chinese Journal of Primary Medicine and Pharmacy 2017;24(9):1289-1292
Objective To observe the effect of sequential therapy of butylphthalide injection and soft capsules for acute cerebral infarction and its influence on plasma lipoprotein phospholipase A2.Methods 120 patients with cerebral infarction were selected in the study,and they were divided into observation group (64 cases) and control group(56 cases) according to the digital table.The control group received conventional therapy plus placebo,the observation group received the sequential administration of butylphthalide injection and butylphthalide soft capsule treatment based on the conventional treatment.Before and after treatment,the plasma lipoprotein phospholipase A2 of the two groups was detected,and the National Institutes of Health Stroke Scale (NIHSS) was evaluated,compared neurological deficit improvement between the two groups and recorded adverse drug reactions of the two groups.Results There were no significant differences in NIHSS score and plasma lipoprotein phospholipase A2 level between the two groups before treatment(all P > 0.05).After treatment,the NIHSS score of neurological impairment,plasma lipoprotein phospholipase A2 level in the observation group were (6.40 ± 5.22) points,(203.26 ± 29.33) ng/mL,those in the control group were (8.59 ± 6.22) points,(253.10 ± 52.99) ng/mL,the differences were statistically significant(t =-1.36,-2.089,P =0.039,0.000).The total effective rate of the observation group was 90.6%,which was higher than 67.9% of the control group,the difference was statistically significant (x2 =9.676,P =0.002).The incidence rate of adverse reactions was similar in the two groups (P > 0.05).Conclusion Sequential therapy of butylphthalide for acute cerebral infarction can improve the neurological function,decrease the level of plasma lipoprotein phospholipase A2,inhibit the inflammation of blood vessels,improve the prognosis of patients.

Objective To investigate the molecular mechanism of the inhibitory effects of rhizoma coptidis on multi-drug resistant uropathogenic Escherichia coli.Methods High-throughput RNA sequencing ( RNA-seq ) was performed to investigate the transcriptome in a multi-drug resistant uropathogenic Escherichia coli strain (NB8) treated with water decoction of rhizoma coptidis .Agar dilution test was used to determine the minimal inhibitory concentration ( MIC) of water decoction of rhizoma coptidis against the NB 8 strain.A growth curve was drawn to evaluate the effects of water decoction of rhizoma coptidis on the growth of NB8 strain.Total RNAs were extracted from the NB 8 strain after treated with the water decoction of rhizo-ma coptidis for 30 minutes and then synthetized to cDNA by reverse transcription after screening out the rRNAs.The HiSeq 2000 sequencing system was used for transcriptome sequencing .The TopHat software was used to map and analyze the RNA-Seq reads, and then Cufflinks was run to assemble transcripts and es-timate their abundances .The differential expression , GO enrichment and KEGG metabolic pathway were fur-ther analyzed .The NB8 strain dealt with normal saline was used as negative control .Results The MIC of water decoction of rhizoma coptidis to NB 8 strain was 12.5 mg/ml.There were 3665 genes expressed in NB8 strain treated with water decoction of rhizoma coptidis and 3430 genes expressed in NB8 strain treated with normal saline .The number of differentially expressed genes was 1428 including 921 up-regulated genes and 507 down-regulated genes .Those differentially expressed genes mainly enriched in the modules of binding and catalysis.The genes concerning cell adhesion , apoptosis and multicellular process were up-regulated, while those concerning the regulation of enzyme activities were down-regulated.Results of the KEGG meta-bolic pathway enrichment analysis showed that the genes concerning synthetic pathway of LPS were signifi -cantly up-regulated as well as those encoding the repair polymerase Ⅲthat was involved in DNA replication . However , the genes concerning fatty acid metabolism , histidine metabolism , thiamine metabolism , folate metabolism and iron carrier in ribosome synthesis showed overall down-regulation.Conclusion The tran-scriptome in uropathogenic Escherichia coli strain treated with rhizoma coptidis was profiled .The main mo-lecular mechanism of the inhibitory effects of rhizoma coptidis on uropathogenic Escherichia coli was to de-stroy the cell wall of Escherichia coli, affect the replication of DNA and regulate the transcription and transla-tion of proteins .This study illustrated that the inhibitory effects of rhizoma coptidis on uropathogenic Esche-richia coli were achieved in multiple levels .

Objective To investigate the distribution of 22 beta-lactamase genes and enzyme activities in multi-drug resistant Acinetobacter baumannii (MDRAB). Methods Sixty-two MDRAB strains were isolated from the First Affiliated Hospital, College of Medicine, Zhejiang University. Twenty-two beta-lactamase genes were analyzed by PCR and verified by DNA sequencing. Enzyme activities of extended spectrum beta-lactamases (ESBLs) , cephalosporinase ( AmpC) and metallo-beta-lactamases ( MBL) were detected by the modified three-dimensional method using enzyme extraction. Results In 62 MDRABs, 51 (82.3% ) , 50 (80.6% ) and 36 (58.1% ) isolates were found to carry blaTEM, blaOXA-23 cluster, and blaADC, respectively. The rest 19 genes were not detected in this study. DNA sequencing and genomic comparison showed that 5 isolates carrying blaTEM had the same genotype as blaTEM-l , 6 isolates carrying blaOXA-23 cluster had the same genotype as blaOXA-23 carbapenemases (accession; CAB69042. 1) , and 2 isolates carrying blaADC had the same genotype as blaADC-like (accession: EU081908). Thirty-two isolates (51.6% ) produced ESBLs and AmpC, 19 isolates (30.6% ) produced ESBLs only, and 1 isolate (1.6%) produced AmpC only; and no isolate produced MBL. Conclusion MDRAB carrying blaOXA-23 carbapenemase and blaADC AmpC in this study are of high drug resistance.

Objective To analyze the clinical manifestations of familial acute necrotizing encephalopathy (ANE)and to improve the recognition of this disease. Methods The clinical data of a 25 - month - old girl with fa-milial and recurrent ANE with evidence of mutation in the RANBP2 gene were collected and analyzed,and the gene examination of their family members was performed. Results A previously healthy girl experienced recurrent ANE epi-sodes at the ages of 8 months,18 months and 25 months,respectively. At each beginning of each episodes the patient presented with lethargy and tremor of limbs following febrile illness of 3 - 4 days,even developed coma and convulsions in the last time. Brain magnetic resonance imaging showed bilateral and high T2 signal changes in thalamus,cerebellum and hippocampus. Abnormal signals also appeared in the brainstem,claustrum,corpus scallosum and cortex(temporal, parietal and cingulate)also appeared abnormal signals. Spinal MRI showed spinal cord involvement. The girl recovered after her first episode;she could speak but could not walk steadily after the second time;after the third episode,al-though she regained consciousness from coma,she could no longer speak or walk. The patient's sister died of encephali-tis at the age of 18 months. Her paternal uncle had suffered from dysnoesia from meningitis at his 17 months of age. The patient and her grandmother,father,uncle and one of her aunts harbored a mutation(c. 1754C ﹥ T)in RANBP2 gene. Conclusions Familial ANE has typical clinical manifestations and characteristic MRI findings. The patient with recur-rent history,especially with positive family history,should have the mutation in RANBP2 gene detected earlier in order to clarify the diagnosis of ANE.
