Objective:To observe the expression and correlation of eIF4E and c-myc in laryngeal squamous cell carcinoma.Methods:Western blot was applied to examine the expression of eIF4E and c-myc on tumor core,transition core and tumor-free core from 36 laryngeal carcinoma patients.The results were statistically analyzed.Results:The overexpression of eIF4E and c-myc protein levels suggests an increasing tendency from tumor-free core,transition core and tumor core;and shows an significant correlation of eIF4E and c-myc expression.Conclusion:The overexpression of eIF4E and c-myc cause the laryngeal carcinoma cell malignant transformation;the correlation of eIF4E and c-myc may provide a basis for gene therapy of laryngeal carcinoma.

ObjectiveTo explore the abilities of automatic processing,controlled processing,selective attention by Stroop color-word test in patients with ischemic cerebrovascular disease.Methods124 patients (aged 60-90 years) with ischemic cerebrovascular disease and 126 cases with age and civilization matched healthy people were examined by Stoop color-word test (SCWT).The SCWT indexes were compared between two groups.Results Reading time of card 1,timeconsuming and error of card 2,4 and Stroop interference effects (SIE) in SCWT had significantly decreased in the patients than in the healthy people (all P＜0.05).ConclusionsThe abilities of controlled processing and selective attention,but not automatic processing are damaged in patients with ischemic cerebrovascular disease.

Objective To explore the adverse effects of formaldehyde(FA)on learning and memory ability of mice and the antagonistic effect of N-acetyl-cysteine(NAC),an antioxidant.Methods Thirty-four ICR mice were randomly divided into four groups,the control(NS,n=8),treated with FA(15 mg/kg,n=9),treated with NAC(100 mg/kg,n=8),treated with FA(15 mg/kg) plus NAC(100 mg/kg,n=9),the treatment was conducted by intraperitoneal injection once a day for seven consecutive days.On the eighth day,the learning and memory ability were tested by using water labyrinth task for seven consecutive days.Results The mice in FA group behaved excited,restless and then turned to repose,moveless and clustering,but this phenomena was not seen in the other groups.There was no significant difference in the body weight of mice among groups.As for learning,latent period in the FA group [(27.15?2.66)s] was significantly longer than that in the control group [(15.83?2.82)s] and the FA+ NAC group[(14.98?2.66)s],and revealed statistical significance(P

OBJECTIVE:To strengthen the supervision of clinical antibiotics use through establishing electronic consultation system. METHODS:Based on hospital information system(HIS)and antibiotic management system,consultation system for anti-biotics of special use(ASU)was established,and the effects of the system after used(Jan. 2014)were also evaluated. RESULTS:Real-time consultation of ASU medical orders and related consultation results inquiry and statistics could be achieved through de-signing ASU consultation application form,establishing consultation experts and confirming their working content,adding statistics function,etc. The consultation have been finished 8275 times from 2014 to 2015. The inspection rate for pathogenic microbes in ASU patients rose from 78.68% in 2013 to 83.90% in 2015. CONCLUSIONS:The establishment and application of ASU consulta-tion system can improve consultation efficiency and quality,so as to promote rational use of antibiotics in the clinic.

AIM: To evaluate the alterations in calcium metabolism of the vascular smooth muscle in the late phase of septic shock and test the hypothesis that nitric oxide might be involved in sepsis-induced vascular hyporeactivity. METHODS: Male Sprague-Dawley rats were subjected to sepsis by cecal ligation and puncture (CLP). 18 hours post CLP,rat aortic rings were employed for measurement of contractile responses by using organ bath technique. RESULTS: In endothelium-denuded aortic rings from CLP rats,concentration-contraction curves to phenylephrine (PE) and KCl were significantly decreased when compared to that from sham control rats. The transient contraction induced by PE in calcium-free Krebs solution and the concentration-dependent contraction to CaCl_2 in KCl-depolarized medium were also markedly reduced. The hyporeactivity was partially reversed by treatment with aminoguanidine,a selective inducible nitric oxide synthase inhibitor. CONCLUSION: An impairment in calcium handling in vascular smooth muscle is involved in the vascular hyporeactivity during the late phase of septic shock,in which an excessive nitric oxide production might be the major mechanism.

Objective To compare the degree of pain in patients after radical gastrectomy under different anesthetic regimens.Methods One hundred and two ASA Ⅰ or Ⅱ patients of both sexes,aged 50-75 yr,weighing 45-70 kg,undergoing elective radical gastrectomy,were randomly divided into 3 groups ( n =34 each):general anesthesia (GA) group,combined general-subcostal transversus abdominis plane block (CGTA) group and combined general-epidural anesthesia (CGEA) group.The patients were sent to the postanesthesia care unit (PACU) after tracheal extubation,and the VAS score on arrival in the PACU was recorded.The degree of pain was evaluated by VAS score,and when VAS scores ＞ 3,the patients received intravenous morphine titration.When VAS scores ≤ 3,morphine titration was stopped and all the patients were connected to patient-controlled intravenous analgesia and/or epidural analgesia pump.The total amount of morphine consumed was recorded at the end of titration,and the occurrence of adverse reactions was also observed.Results Compared with groups GA and CGTA,the incidence of moderate to severe postoperative pain was significantly decreased in group CGEA (P ＜0.01).The incidence of severe postoperative pain,the VAS score on arrival in the PACU and the total amount of morphine consumed were decreased gradually in groups GA,CGTA and CGEA ( P ＜ 0.01 ).The incidence of sedation was significantly lower in group CGEA than in group GA (P ＜ 0.01 ).There were no significant differences in the other adverse reactions among the three groups ( P ＞ 0.05 ).Conclusion The degree of pain is reduced gradually in patients after radical gastrectomy under GA,CGTA and CGEA.

Objective To explore the association of Crohn's disease (CD) with T cell immunoglobulin and mucin domain 3 (Tim-3) gene polymorphisms in patients of Zhejiang Han population in China.Methods A total of 308 CD patients and 573 age-and sex-matched healthy controls were enrolled in our study.Two single nucleotide polymorphisms (SNPs) of Tim-3 (rs1036199 and rs10515746) were examined by the improved multiple ligase detection reaction technique (iMLDR).Analyses of linkage disequilibrium and haplotype were also performed by Haploview 4.2 software in all study subjects.Results In general,the allele and genotype frequencies of Tim-3 (rs1036199 and rs10515746) were not statistically different between CD patients and the controls (all P ＞0.05).According to the Montreal Classification,CD patients were divided into different subgroups.The variant allele (C) and genotype (AC + CC) of rs1036199 were more frequent in CD patients with penetrating diseases than in the controls (10.4％ vs 1.7％,P =0.002;20.8％ vs 3.5％,P =0.023).Similar conclusions were also drawn for the variant allele (A) and genotype (CA + AA) of rs10515746 in patients with penetrating diseases when compared with the controls (10.4％ vs 2.2％,P =0.000;20.8％ vs 4.2％,P =0.033,respectively).The two SNPs of Tim-3 were in strong linkage disequilibrium (D'=1.0,r2 =0.928).The haplotype (AC) formed by their wild-type alleles (A) and (C) was decreased in patients with penetrating CD compared with the controls (89.6％ vs 98.3％,P =0.000).However,the haplotype (CA) formed by their variant alleles was more frequent in patients with penetrating CD than in the controls (10.4％ vs 1.6％,P =0.000).Conclusions Tim-3 (rs1036199 and rs10515746) variations might be correlated with the enhanced risk of penetrating diseases in CD patients.Furthermore,the haplotype (AC) and (CA) formed by the two SNPs might be a protective and a risky factor for penetrating CD respectively.

Low frequency sensorineural deafness is a common subtype of idiopathic sudden deafness. Certain patients suffered recurrent attacks without vertigo, much alike Meniere's disease. Few of them developed into definite Meniere's disease during long-term follow-up in many clinical studies. Although the pathophysiology of recurrent low frequency deafness is yet unknown, the desease is considered associated with early state of endolymphatic hydrops or migraine. Otologists shall be aware of its clinical course and careful explanation is necessary at time of initial informed consent.
