Objective To investigate the minimal inhibitory concentration (MIC) of Pseudomonas aeruginosa to antibacterial agents which were induced by disinfectants.Methods The susceptibility test of 68 strains from clinic was determined by VITEK-2 system.The MIC of povidone iodine,glutaraldehyde and chlorhexidine was determined by agar dilution method.68 strains were induced by different concentrations of three kinds of disinfectants for eight times.The concentration of three kinds of disinfectants was lower than their MIC.The MIC before and after inducement was determined by micro dilution.In the mean-while,strains of their MIC raised to antibiotics were inoculated on plate agar containing the PAβN which was the efflux pump inhibitor,in order to determine the phenotype of efflux pump.Results Six strains,MIC in 68 strains significantly changed after induction of disinfectants.The MIC of these six strains was higher than pre-induced to some antibacterial agents such as FQNs,cephems and carbapenem.The induction of povidone iodine and gilutaraldehyde were more obvious,and five strains,phenotype of efflux pump were positive after being induced by these two disinfectants.Conclusions The antimicrobial susceptibility of some Pseu-domonas aeruginosa will change after being induced by some disinfectants and the efflux pump will play an important role in this process.So the reasonable application of disinfectants were indispensable,in order to decrease the resistance and the opportunity of nosocomial infection.

Objective To study the psychological conditions of HIV/AIDS patients' families.Methods The non-structural interview was done with 4 HIV/AIDS patients' families.The data were analyzed for summarizing the themes.Results Six themes were summarized including suspicion and denial,humiliation and discrimination,helplessness and guilty,fear and sadness, desperate,threat and revenge.Conclusion HIV/AIDS patients’families are under tremendous psychological pressure and economic pressure,and their quality of life is very low.Therefore,it is necessary to lower the negative emotions in HIV/AIDS patients' families so that their quality of life is to be increased.

ObjectiveTo study the effects of dexamethasone local injection as an adjunctive therapy for Hashimoto thyroiditis (HT). Methods60 HT cases were equally divided into 2 groups at random. The patients in the control group were given euthyrpx while the patients in the treated group were injected dexamethasone in addition to the medicine used in the control group. The thyroid characters such as thickness, lymphocytic infiltration and changes of thyroid follicle were observed. The patients were followed up before treatment and 4, 12, 24weeks and 1 year after treatment. ResultsIn the treatment group, all thyroid glands turned significantly softer,and the mass became smaller compared with that in the control group. The pathology of thyroids indicated that lymphocytic infiltration decreased, local immune reaction was ameliorated, and no obvious hormone side effects were observed. ConclusionLocal use of dexamethasone can modify the structure and function of thyroid.

Objective To study the relation between thyroid nodule and urine iodine and to provide a scientific basis for etiological research of thyroid nodule.Methods 178 cases of thyroid nodule were detected urine iodine concentration (μg/L) by As ( Ⅱ ) 2Ce4 + catalytic spectrophotometry.160 normal people were set as control group.Data of the 2 groups and the correlative clinical information were analyzed.Results The median urine iodine concentration was 116.2 μg/L for the 178 cases of thyroid nodule,217.2 μg/L for the control group.Among the 178 cases,the median urine iodine concentration was 125.6 μg/L for the 92 cases with nodule size ＞ 10 mm and 136.4 μg/L for the 86 cases with nodule size ＜ 10 mm.The difference of urine iodine had no statistical significance between the thyroid nodule group and the control group.There was no correlation between urine iodine and the size of thyroid nodule as well as sex.Conclusions No correlation is found between urine iodine and thyroid nodule.Patients with thyroid nodule,no matter male or female,don't have to restrict iodine intake excessively.

Objective:To investigate the effect of chronic ethanol consumption on sensory information transmission in the cerebellar molecular layer and reveal the mechanism of chronic alcoholism on sensory information transmission and integration in the cerebellar cortex.Methods:Fifty healthy male ICR mice aged 6-8 weeks were randomly divided into saline group(control group)and ethanol consumption group(alcohol group) according to the random number table, with 25 mice in each group.The mice in alcohol group were injected intraperitoneally with 20% ethanol daily, while the mice in control group were injected with the same dose of normal saline. All mice were injected intraperitoneally once a day for 28 days.Through electrophysiological technology, patch-clamp amplifier and data acquisition software were used to record the changes in cerebellar molecular layer field potential of mice in the alcohol group and control group induced by sensory stimulation.Clampfit 10.3 software was used to record and analyze the electrophysiological data. SPSS 22.0 software was used for statistical analysis. Paired t-test and one-way ANOVA were used to analyze the differences before and after treatment. Results:After giving the stimulation of wind blowing, the amplitude of P1 in alcohol group was significantly higher than that in control group ((121.31±3.5)%, (97.2±2.7)%; t=26.08, P<0.05), and the area under the P1 curve (AUC) of the alcohol group was significantly lower than that of the control group ((127.1±4.2)%, (102.2±3.5)%; t=22.95, P<0.05). There was no significant difference in N1 amplitude between the two groups (P>0.05). When L-NNA, an inhibitor of nitric oxide synthase, was perfused into the brain surface of mice, the amplitude of P1 in alcohol group was significantly lower than that before administration ((76.2±4.8)%, (103.5±3.6)%; t=22.60, P<0.05), but there was no difference of the amplitude of P1 before administration and after elution ((101.5±4.6)%) ( t=1.70, P>0.05). After the L-NNA was perfused, the AUC of P1 was significantly lower than that before administration((72.4±5.6)%, (102.7±2.66)% ( t=24. 58, P<0.05), and there was no significant difference between before administration and after elution( (100.6±3.5)%, t=1.81, P>0.05). When L-NNA was perfused into the brain surface of mice, the amplitude of P1 in control group was (104.3±1.6)% and it had no differences compared with before administration(102.2±5.6)%, t=1.84, P>0.05) and after elution(102.5±4.5)%, t=1.92, P>0.05). And the AUC of P1 in control group after perfused L-NNA had no differences compared with before administration(103.5±2.6)%, (102.5±4.6)%) and after elution((101.9±3.7)%, t=0.99, 1.81, both P>0.05). When the mouse brain surface was perfused with NO donor SNAP, the amplitude of P1 in the control group was significantly higher than that before administration( (128.2±3.4)%, (103.5±2.6)%; t=28.89, P<0. 05) and there was no difference between before administration and after elution( (105.4±4.2)% , t=1.93, P>0.05). The AUC of P1((125.4±4.4)%) was higher than before administration((104.3±4.6)% , t=16.60, P<0.05) and there was no difference between before administration and after elution(103.5±4.2)%, t=0.65, P>0.05). Conclusion:Chronic ethanol consumption significantly enhances the inhibitory response, and the enhancement of inhibitory components stems from the activation of the NO signaling pathway.

Objective To find a potential link among ABO blood group,lipid profiles and coronary artery disease (CAD) and to estimate the effect size of connection using mediation analysis model.Methods A total of 898 consecutive patients undergoing coronary angiography were enrolled,and divided into CAD group and non-CAD group according to angiographic findings.According to ABO blood group,patients were divided into O blood group and non-O blood group,as well as A blood group and non-A blood group.Baseline characteristics among various groups were compared and the association of ABO blood group,CAD and lipid profile was explored.Results Subjects of blood type A had higher concentration of total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) compared with that of non-A type (TC:(4.43 ± 1.12) mmol/L vs.(4.18 ± 1.09) mmol/L,LDL-C:(2.79 ±0.99) mmo/L vs.(2.59-± 1.01) mmol/L,all P ＜ 0.01).TC and LDL-C were significantly higher while high density lipoprotein cholesterol (HDL-C) and ApoA Ⅰ levels were significantly lower in CAD group than in non-CAD group (TC:(4.36 ± 1.05) mmol/L vs.(4.13 ± 1.16)mmol/L,LDL-C:(2.61 ±0.87) mmol/L vs.(2.47 ±0.94) mmol/L;ApoA Ⅰ:(1.38 ± 0.29) mmol/L vs.(1.45 ± 0.33) mmol/L;all P ＜ 0.01).After adjustment for traditional cardiovascular risk factors,blood group A and TC remained significantly associated with the risk of CAD (OR =1.88,95％ CI 1.280-2.774,P ＜0.01;OR =1.03,95％ CI 1.018-1.033,P ＜0.01,respectively).Specially,mediation analysis indicated that 10.5％ of the effect of A blood group on CAD was mediated by TC levels (P ＜0.01).Conclusion Our data indicate that there is an association between ABO blood group,TC levels and risk of CAD.Around 10.5％ of the effect of A blood group on CAD is mediated by TC levels.

Objective To provide basic references for the utilization of health educational prescription in community and to evaluate the intervention effects of health educational prescription in child vaccinoprophylaxis. Methods A total of 1055 participants ( age ranged from 1-24 months ) along with their parents were recruited from the community received routine health education about vaccinoprophylaxis. Participants were randomly divided into control group (n=495) and intervention group (n=560). All parents in the control group received the conventional health education, while parents in the intervention group received the additional health education prescription based on the conventional health education. The rate of adverse reaction of vaccinoprophylaxis in children and the satisfaction level in parents for health care were compared between two groups after six months′ interventions. Results The incidence rate of adverse reaction in the intervention group were lower than that of the control group (P<0. 01). The satisfaction level of parents in the intervention group was 97. 3% and was 90. 9% in the control group (χ2 =4. 24,P<0. 05). Conclusions The health educational prescription can reduce the incidence of adverse reaction in children and improve the satisfaction level in parents. It is worthy of promotion in community child vaccinoprophylaxis.
