Objective To explore the clinical efficacy of aztreonam in combination with cefepime for the treatment of urinary tract infections.Methods A randomized block grouping,123 cases of urinary tract infections were divided into observation group,aztreonam group and cefepime group,41 cases in each group.The observation group was treated with aztreonam (2.0g) and cefepime (2.0g),control group were given aztreonam and cefepime,respectively.The treatment time lasted 7 days.Results The total effective rate of observation group was 95.1％,compared with cefepime(85.4％)or aztreonam(82.9％) group,the difference was statistically significant(x2 =12.89、13.56,all P ＜ 0.05).After the end of treatment,the observation group bacterial clearance rate (94.3％) was slightly higher than that of cefepime group or aztreonam group.Each group had only minor adverse reaction,which did't affect the continued medication.And the difference in the incidence was not statistically significant(P ＞0.05).Conclusion Cefepime joint aztreonam in the treatment of urinary tract infection can improve the therapeutic efficacy,and adverse events doesn't increase.

Objective To observe the abnormalities of speech production when developmental stutterers reading four-character Chinese words aloud and to discuss its etiology mechanisms. Methods The speech production results between the developmental stutterers and normal speakers when reading four-character Chinese words under the voice reaction time paradigm and computerize program in acoustic data analysis were compared. Results The voice duration time (VDT) of developmental stuttering group (791±82) ms was longer than that of the control group (687±93) ms (t=3.42,P<0.01),but the differences of voice reaction time (VRT) and voice error rate (VER) were not significant between these two groups. Conclusion The speech fluency disorders of developmental stuttering maybe mainly exist in the stage of speech movement, and probably due to the speech production disturbed with language processing.

Objective To investigate the Chinese characters processing in healthy subjects with functional magnetic resonance imaging (fMRI). Methods 10 healthy subjects were asked to finish the dual-task paradigm Keying/Reading and single-task paradign Keying or Reading.The active area and partial lateralization index in brains of them were investigated with fMRI with block design. Results and onclusion The tasks activated the right inferior frontal gyrus, bilateral parietal and cerebellar cortex. The laterality index showed that the left brains were more active in the tasks.

Objective Evaluate the immunotoxicity of Ginenoside Compound K Injection.Methods Active Systemic Anaphylaxis (ASA)tests and Passive Cutaneous Anaphylaxis (PCA)tests were used to evaluate Ginenoside Compound K Injection.Results In the ASA tests,positive control group showed pole-strength anapbylaxis,both the high-dose group and the low-dose group of Ginenoside Compound K Injection didn't produce allergic reaction and the body weights of all groups showed no significant differences.In the PCA tests,all rats of positive control group caused blue spots with their diameters bigger than 5 mm (diameters on the left side of blue spots was (10.1± 3.34) mm and diameters on the right side of blue spots was(7.57± 1.94)mm.Serum IgE was significantly increased.While both high dose and low dose of Ginenoside Compound K Injection group didn't show blue spots with their diameters greater than 5 mm and their IgE levels showed no significant differences compared with negative control group.Conclusion Ginenoside Compound K Injection showed no immunotoxicity under these experimental conditions.

[Summary] Activating transcription factor 4 (ATF4) is an alkaline leucine zipper transcriptional factor ,which is involved in many physiological metabolism processes such as stress response ,inflammation and tumor growth. Moreover ,recent studies have shown that ATF4 also plays a key role in regulating lipid and glucose metabolism ,insulin secretion and insulin sensitivity ,which may related to pathways such as endoplasmic reticulum stress (ERS ) ,peroxisome proliferator‐activated receptor gamma coactivator (PGC1α) and target of rapamycin (TOR). This article summarized the recent research progress of ATF4 in regulating glucose and lipid metabolism.

Objective To investigate the effect of attention training on cortical activation area and lateralization index in interference effect of dual-task paradigm as the poststroke nonfluent aphasiacs processing the Chinese character tasks. Methods 20 cases with nonfluent aphasia after stroke were divided into the training group and the control group, who accepted attention training and cognitive training respectively, 30 min a time, 5 times a week, for 4 weeks. They were investigated the cortical activation area and lateralization index caused by interference effect of dual-task paradigm under block design. Results The right inferior frontal gyrus, bilateral parietal and cerebellar cortex were activated before training in both groups, and more activated after attention training, but no change after cognitive training. Lateralization index suggested that the right brain was more activated before training, while the left side was activated after attention training, but no change after cognitive training. Conclusion The right inferior frontal gyrus, bilateral parietal and cerebellar cortex are very important in solving the dual task interference in the attention stage, and they are activated after attention training. It indicates that attention training makes a significant functional reorganization on Chinese character processing in poststroke nonfluent aphasiacs.

Objective To explore the influence of attention training on Chinese character processing capability in poststroke nonfluent aphasiacs. Methods 60 stroke patients with nonfluent aphasia and cognition dysfunction were divided into control group (n=30) and experimental group (n=30). The trainings (attention training and cognition training) were respectively 30 minutes each time, 5 times each week for 4 weeks. The change of reaction time and error rate were compared before and after they were performing the orthographic, semantic and phonological tasks. Results In the dual-task paradigm the change of reaction time and error rate in orthographic and semantic tasks of the experimental group were all higher than the control group (P<0.001). But there was no difference between the two groups in the phonological task (P>0.05). In the single task paradigm there was no difference between the two groups (P>0.05). Conclusion 1. Attention training can improve the processing capacity significantly in orthographic and semantic tasks in the dual-task paradigm because the volume and distributive ability of attention improve significantly. 2. Attention training can't improve the processing capacity in phonological tasks in the dual- task paradigm because reading aloud and judging are required to process the vowel simultaneously. So that the competion intensifies and it is more difficult to finish the task. 3. In the single task paradigm, there is no significant difference between the influence of the two trainings in poststroke nonfluent aphasiac because the single task needs little attention and the change in the control group is enough.

Objective To examine the performance of developmental stutterers in processing Chinese character to determine their basic cognitive abilities of Chinese language.Methods The reaction time and error rates of developmental stutterers and fluent speakers were compared when they performed orthographic,phonetic and semantic judging tasks in the manual reaction time paradigm.Results The differences of reaction time in orthographic,phonetic and semantic judgment and the error rates in orthographic and semantic judgment between both groups were not significant(P>0.05);however,the difference of error rate in phonetic judgment between the both groups were nearly significant(P=0.053).Conclusion The only disability existed in developmental stutterers seems to be the in phonetic abstracting or encoding processes,which is partly in accordance with the covert repair hypothesis.

ObjectiveTo investigate the semantic induce effects in reading disorder of the Chinese deep dyslexia. MethodsA patient with deep dyslexia was researched with initials inducement (as phonetic inducement), semantic-related words inducement, numeral inducement, quantifier inducement, context inducement and actual object inducement (all as semantic inducement). ResultsThe rate of correct results were more with semantic inducements than with phonetic inducement (91.30%, 76.67%, 94.44%, 83.33% vs 44.44%, P<0.001). ConclusionThe semantic induce training is more effective than the phonetic induce training on Chinese deep dyslexia.
