Objective　To study diagnostic significance of blink reflex(BR) in cranial Guillain-Barré Syndrome (cGBS). Methods　A comparative study was carried out on BR in 7 cGBS cases and 39 normal subjects.Results　As compared with controls,the cGBS group showed significant differences on latency and amplitude of R1,R2i, R2c component of BR,M wave and R1 conduction time (R1CT) inside the cranial part(P<0.001). Conclusion　The result suggested that BR and facial electromyogram were of great significance in the diagnosis of cGBS and might provide an objective index for clinical differential diagnosis.

ObjectiveTo investigate changes of the level of serum thyroxine after different style operation on thyroid gland,for guiding replacement therapy after surgery. MethodsTo select patients randomly,include the excision of adenoma of thyroid、the lobectomy of unilateral thyroid、the subtotal ectomy of bilateral thyroid and total resection of bilateral thyroid quaque forty,among the total,the patients who suffererd the total resection of bilateral thyroid take thyroxine 40mg bid orally everyday. To detect the serum thyroxine in all of the patients, when preoperation、ten days after operation、one month after operation and three months after operation. ResultsThe serum thyroxine in patients who suffererd the excision of adenoma of thyroid were had no marked changes compare to preoperation; Serum FT3 、FT4 in patients suffer the lobectomy of unilateral thyroid are lower than preoperation when ten days after operation (P＜0.01) ;Serum FT3、FT4 in patients sufferred subtotal ectomy of bilateral thyroid were lower than preoperation,when ten days after operation and one month after operation( P ＜ 0.01 ), then returned to the level of preoperation when three months after operation;the serum thyroxine of patients who sufferred the total resection of bilateral thyroid had no marked changes compare to preoperation,when they taker thyroxine 40mg bid orally everyday. ConclusionThe serum thyroxine level of patients who suffer the lobectomy of unilateral thyroid、the subtotal ectomy of bilateral thyroid and total resection of bilateral thyroid is lower than preoperation at different degree, they should be given replacement therapy properly.

Objective Construction of a predicting model of uncertainty in illness based on Mishel's theories of uncertainty in illness in a sample of the postoperative patients with digestive system tumors undergoing chemotherapy.Methods By convenient sampling method,MUIS-A,MSAS,SSRS were used to evaluate 484 postoperative patients with digestive system cancer during chemotherapy period,and then AMOS 17.0 software was used to perform analysis.Results The score of uncertainty in illness of postoperative patients with the digestive system cancer undergoing chemotherapy was in the medium level (89.86+11.84) points; Structure provider (social support,economic income) could not only reduce the uncertainty directly,but also had an indirect effect on the uncertainty by stimuli frame (symptoms pattern,event familiarity).Conclusions Structure equation model can be applied to the uncertainty in illness model construction,so as to help medical staff manage uncertainty in illness pertinently.

Objective To investigate the effect of total sleep deprivation (TSD) shown in the electroencephalogram (EEG) power spectra in healthy young men. Method 20 healthy young male volunteers (19～22 years old) were subjected to 50 hours of TSD. EEGs were recorded 8 times (6 hours intervals) during TSD. EEG power was calculated for six bands at all 16 derivations.Results 50 hour TSD induced an increase in ? power at the other derivations except both occipitals ( P

Object To investigate the features of health related quality of life ( HRQOL) among elderly hypertensive patients with different body mass index (BMI) so s to provide evidence for the health promotion of hypertensive. Methods A cross-sectional survey of health status data from a population of 1281 elderly hypertensive patients from Beijing and 8 provinces of China ( Jiangsu, Anhui, Gansu, Qinghai, Fujian, Jilin, Jiangxi, and Henan) was made in the study. Analysis of variance was applied to compare the differences in HRQOL of elderly hypertensive patients in different BMI categories. Results For the elderly hypertensive patients with low body mass index, the scores of 8 dimensions and scores in physical component summary (PCS) and mental component summary( MCS) of SF-36 were the lowest;except the role-emotional(RE) dimension,the scores of other 7 dimensions,PCS and MCS were significantly different(PF,RP,BP,GH,VT,MH, P<0.01; SF,PCS,MCS, P<0.01). Comparing the scores between any two groups in PCS, the scores of patients with low body mass index were significantly lower than normal weight group (62.30 ± 22. 12 vs72.40 ±20.86, P<0.05) .overweight group (62.30 ± 22.12 vs 74.97 ± 19.20, P<0.05 ) and obese group (62.30 ± 22.12 vs 74.57 ± 19. 22, P < 0.05 ). Comparing the scores between any two groups in MCS,the scores of patients with low body mass index were significantly lower than normal weight group (68. 81 ± 20. 48 vs 74. 70 ± 20.41, P < 0. 05), overweight group (68. 81 ± 20. 48 vs 78.08 ±18.23, P<0.05) and obese group (68.81 ±20.48 vs 78. 69 ± 17.77, P<0.05); the score of normal weight group was significantly lower than the overweight group (74. 70 ±20. 41vs 78. 08 ±18.23, P<0.05). Gender Stratification showed that females with low body mass index had worse HRQOL than males. Conclusion The HRQOL of elderly hypertensive patients with low body mass index is significantly lower than normal weight patients, overweight patients and obese patients, the health promotion of elderly hypertensive patients with low body mass index should be paid more attentions, especially females with low body mass index.

Objective　To explore the development of endogenous CO and its mechanisms in asthma.Methods　50 guinea pigs were equally separated 5 groups.After the models of asthmatic guinea pigs were established in 4 groups,3 groups of them were treated with dexamethasone,the specific stimulator(hemin)and inhibitor(Sn-PP)of HO-1 respectively.The rest of groups were asthmatic one and normal control one(NCG).From all tested animals,the COHb in blood and lung HO-1 activity were examined,the lung tissues were pathologically observed and immunohistochemically stained.Results　In asthmatic and hemin stimulated groups,the levels of COHb with enhanced expression of lung HO-1 and their activity were significantly increased compared with NCG(t=4.43～9.97,P＜0.01).For example,the lung HO-1 activities in asthmatic group were (881±361)pmol/(mg*pro*h),COHb (4.94±2.15)% respectively.In dexamethason prevented and Sn-PP inhibited groups,however,all determined levels were markedly reduced compared with asthmatic group(P＜0.01).Conclusion　The increased HO-1 had resulted in the growth of endogenous CO in asthma.

Objective To analyze the structure of leadership questionnaire for nursing managers.Methods A total of 184 head nurses in Anhui were investigated with the leadership questionnaire for nursing managers.SPSS13.0 and AMOS17.0 software were used to test the reliability and validity.Results The correlations between the items and total scale ranged from 0.431-0.687(P＜0.05 or P＜0.01) and the Cronbach' sα was 0.841.Single factor analysis results indicated that all factor loadings to their items were 0.542-0.782(P＜0.05).The multiple factor analysis results showed that first-order factors model and second-order factors model of leadership for nursing managers fitted well.Conclusion The leadership questionnaire for nursing managers is proved to have good psychometric characteristics and can be used to assess the leadership of nursing managers.

Objective To investigate the empathy of clinical nurses and analyze the influencing fac-tors.Methods Totally 465 clinical nurses were investigated with demographic data and interpersonal Reactivity Index-C (IRI-C).Results Mean score of the empathy of clinical nurses was (53.77±8.99)points with a medium level.Age,working years,whether or not to engage in management work were the main predictors of empathy.There were no significant differences in nurses with different genders,marital status,professional titles,education degree,hospital grades.Conclusions The length of the working years is one of the important factors of nursing unit.Common clinical nurses should be involved in the nursing manage-ment.Clinical nurses should pay attention to the study and discussion about empathy knowledge in order to improve their level of empathy.
