Objective To compare the clinical effect of different doses of oxycodone on endotracheal intubation during general anesthesia induction period.Methods Ninety-five patients with endotracheal intubation general anesthesia were selected as the research subjects,and the patients were randomly divided into group A,group B and group C.31 patients in group A received intravenous administration of oxycodone 0.20mg/kg,32 patients in group B received intravenous administration of oxycodone 0.25mg/kg,and 32 patients in group C received intravenous administration of oxycodone 0.30mg/kg.The adrenaline,norepinephrine,dopamine concentration,as well as mean arterial pressure and heart rate at different time points were compared among the three groups.Results The mean arterial pressure and heart rate at T0 time point were decreased to varying extent compared with those at T1 time point(t =23.618,7.412;22.928,9.063;32.636,9.422,P =0.000,0.000;0.000,0.000;0.000,0.000).The heart rate,mean arterial pressure at T2,T3 and T4 time points in group A were increased compared with T0 time point (t =13.834,6.506,7.015;17.604,14.796,16.323,P =0.000,0.000,0.000;0.000,0.000,0.000).The adrenaline,norepinephrine and dopamine at T2,T3 and T4 time points in group A were increased compared witb T0 time point (t =121.662,64.533,15.687;31.498,16.933,9.286;39.712,116.049,147.102,P =0.000,0.000,0.000;0.000,0.000,0.000;0.000,0.000,0.000).The heart rate,mean arterial pressure,adrenaline,norepinephrine and dopamine at T2,T3 and T4 time points in group B and group C were decreased significantly compared with those in group A (t =19.586,31.972,16.844,27.087;14.046,14.822,15.377,23.826;7.756,14.396,13.268,23.342,100.573,1 04.010,37.612,38.892,107.377,117.969;56.135,56.757,24.223,25.300,95.057,82.088;22.878,25.731,5.532,5.934,134.763,83.628,P =0.000,0.000,0.000,0.000,0.000,0.000;0.000,0.000,0.000,0.000,0.000,0.000;0.000,0.000,0.000,0.000,0.000,0.000;0.000,0.000,0.000,0.000;0.000,0.000,0.000,0.000;0.000,0.000,0.000,0.000),and the differences were statistically significant (all P ＜ 0.05).Conclusion During the induction of general anesthesia,the appropriate dose of oxycodone in patients with endotracheal intubation was 0.25mg/kg,which could effectively maintain the hemodynamic stability,such as mean arterial pressure,and could reduce the stress response.

Objective To investigate the relationship between plasma P substance(SP),atrial natriuretic peptide(ANP) and renal function in chronic renal failure(CRF).Methods SP and ANP were measured by radioi m munoassay in normal control and CRF before and after hemodialysis(HD),serum creatinine(Cr) was determined simultaneously.Results SP before HD was significantly higher than that of control(P

Objective To evaluate the effect of oral levothyroxine plus intrathyroidal injection of dexamethasone on conversion of subclinical hypothroidism caused by Hashimoto's thyroiditis.Methods 80 subjects with Hashimoto thyroiditis were randomly divided into 2 groups.Subjects in levothyroxine group(40 cases) were treated with oral levothyroxine sodium,subjects in dexamethasone group(40 cases) were treated with oral levothyroxine plus intrathyroidal injection of dexamethasone.Serum free triiodothyronine(FT_3),free thyroxine(FT_4),sentient thyrotropin(sTSH) and other parameters were evaluated before treatment and after treatment in patients with Hashimoto's thyroiditis.Results The content of FT_3,FT_4 after treatment were obviously higher than that before treatment(t=2.123,P

Objective To study the status of telomerase activity during the development of thyroid tumors,and to determine whether telomerase activity can be used clinically as a molecular marker in the differential diagnosis of thyroid cancer.Methods Telomerase activity was measured in 37 thyroid carcinomas,33 benign thyroid lesions and 30 normal thyroid tissue samples by means of telomerase repeat amplification procedure-polymerase chain reaction(TRAP-PCR).The assay was also applied to 15 fine needle aspirates(FNAs) of thyroid carcinomas to test its sensitivity.Results Thirty-one of 37 thyroid carcinomas(83.8%),7 of 33 benign thyroid lesions(21.2%),and 4 of 30 adjacent normal thyroid tissue asmples expressed telomerase activity,15 FNAs also had positive telomerase activity,just as their corresponding tissue specimens.The quantitative analysis showed that the telomerase activity was significantly higher in thyroid carcinomas than that in benign thyroid tissue samples.And medullary carcinomas and anaplastic carcinomas had higher levels of telomerase activity than papillary carcinomas.Conclusion Telomerase activity is a good marker for thyroid carcinomas.The quantitative TRAP-PCR might have more potential application in the differential diagnosis of tumors and the estimation of tumor progression and prognosis.And this sensitive assay could become a useful new modality for supplementing microscopic cytopathology in the detection of cancer cells in small tissue samples and FNAs.

Objective To explore the correlation between nurses' work alienation and silence behavior.Methods 603 registered nurses were recruited from a tertiary hospital in Guangzhou.They were investigated with Alienation Scale and Work Silence Behavior Scale.Results The scores of work alienation and silence behavior were (34.35±6.53) points and (37.66±6.46) points respectively,and both of them were at the medial level.Work alienation was positively related to silence behavior (r=0.603).All dimensions of work alienation were positively related to all dimensions of silence behavior (P ＜ 0.01).The predictors of silence behavior were age,nursing working years,job title,department,frustration,helplessness and meaningless,explained 42.2％ of its variance.Conclusions Work alienation has positive effect to silence behavior.The administrators in hospitals should focus on nurse,work alienation and silence behavior,and reduce silence behavior by reducing work alienation.

Non-arteritic anterior ischemic optic neuropathy (NAION) is one of the most common acute optic neuropathy in adult characterized with impaired visual acuity and visual fields.The pathogenesis of NAION mostly result from the interactions between the systemic risk factors (such as diabetes mellitus,night hypotension, hereditary) and the local ocular risk factors (such as small optic disc and vitreo-papillary traction).A fully promoted diagnosis and treatment of NAION are based on the higher levels of clinical cvidence, as well as the comprehensive assessment of relationship between the systemic and ocular risk factors in the pathogenesis of NAION.Secondary optic neuropathy of NAION and the early diagnosis with effective treatment of the fellow eye would be highly emphasized.

Indoor microbial contaminants may induce the eye stimulation, asthma, allergic dermatitis and pneumonia and infectious diseases as well, even to die due to the serious infection. The main contamination source is constructional materials (especially the decorative materials) of the inner space of the building as well as the electric appliance (especially the center air conditioner system). Not only the direct stimulation from the chemicals released, but also all of them provide a suitable environment for some pathogenic microorganisms in the inner space of room. Using the anti-microorganism decorative materials to inhabit/decrease the microorganisms may improve the indoor air quality.
