OBJECTIVE: To explore the application of the Dexmedetomidine utend drug induced sleep endoscopy. METHOD: Forty-four OSAHS patients diagnosed by PSG randomly were divided into group A (Dexmedetomidine group) and group B (Propofol group), each group of 22 cases. Group A: pump the Dexmedetomidine (1 microg/kg) over 15 minutes. Once the patient reached a satisfactory level of sedation, the electronic nasopharyngoscope was introduced into the nasal cavity group B: the propofol (2 mg/kg) was intravenous injected, use the same exmination after the object patients falling asleep. If not, double the injection dose of the two group. Observe and record the patient vital signs, EEG and sleep time, and handle the complications. RESULT: The study was successfully completed both in group A and B. Mean arterial pressure (MAP) in group B was lower than group A during the examination significantly (P < 0.05). The time falling to sleep in two groups were (13.4 +/- 2.5) min and (6.6 +/- 1.2) min, and the time in group A was much longer than that in group B. The lowest oxygen saturation during the examination in two groups were 0.835 +/- 0.096 and 0.691 +/- 0.095, and the difference was statistically significant. There was no incidence of adverse reactions in two groups. CONCLUSION Compared with propofol, Dexmedetomidine is a safer sleep-inducing drug, and it can be used for clinical sleep endoscopy.

Objective Changes of thyroid stimulating antibody(TSAb) and thyroid stimulating blocking antibody(TSBAb) in the treatment of anti-thyroid drugs(ATDs), and the effect of ATDs combining with levothyrocine(LT4) on TSAb and TSBAb were analyzed. Methods Using recombinant Trxfus. TSHRn protein and Trxfus. TSHRc protein as antigens, and TSH receptor antibody(TRAb)-N(TSAb binding hot spots), TRAb-C(TSBAb binding hot spots)in the serum of thyroid disease patients were measured with ELISA. The changes of TRAb-N, TRAb-C over 36 months in 117 TRAb-N positive Graves′ patients with hyperthyroidism were analyzed retrospectively. In the course of treatment, 41 cases as A group with ATDs and LT4 treatment, 76 cases as B group with only ATDs, The changes of TRAb-N and TRAb-C were observed in the two groups. Results (1)According to the change of TRAb-N, 117 TRAb-N positive Graves′ patients with hyperthyroidism were different. In group Ⅰ, 10 patients continued to have persistently positive TSAb and continued to have hyperthyroidism, remission rate 0%. In group Ⅱ, 17 patients showed complicated TRAb-N changes, 12 of 17 patients got relapse, 5 of 17 patients got remission, remission rate 29.4%. And in group Ⅲ, with TRAb-N dropping gradually, 15 of 89 patients got relapse, 74 of the 89 patients got remission, remission rate 83.1%. Three groups were significantly different with x2 test(P<0.01). One of the 117 TRAb-N positive Graves′ patients with hyperthyroidism developed TRAb-C positive hypothyroidism. (2)According to combining with and without LT4 during the treatment of ATDs,the patients were divided into 2 groups(Group A: ATDs combined with LT4; Group B: only ATDs). These 2 groups were significantly different in TRAb-N at baseline and 3 months(P<0.01), TRAb-C between two groups were not significantly different in all times(P>0.05). Conclusion TSAb and TSBAb can be used to document TRAb-function, which is significant for us to predict the changes of thyroid function. During ATDs treatment, the temporary early low-dose application of LT4 did not significantly affect TSAb and TSBAb.

Objective To select and express a human thyrotrophin receptor antibody (TRAb) Fab fragment from phage antibody library constructed with phage display technology. Methods With immobilized antigen, the reconstructed humanized TRAb Fab library was enriched by five rounds panning (adsorption-elution-amplification). The TSAb Fab and TBAb Fab fragment were selected by coated fusion proteins of hTSHRn and hTSHRc. The positive clones were identified and selected by Phage-ELISA. TRAb positive clones were identified by PCR and double restriction enzyme digestion. The soluble TRAb (TSAb, TBAb) Fab fragments were expressed. TRAb (TSAb, TBAb) Fab fragments were identified by Western blotting assay. The DNA fragment was sequenced from the positive clones. Results Following five rounds of biopanning, TRAb (TSAb,TBAb) Fab phage antibody was screened. The enrichment effect reached to 77 times and 94 times. The soluble TRAb (TSAb,TBAb) Fab antibodies were expressed from positive clones and identified by phage ELISA. Western blotting analysis showed that the phage displaying Fab had significant binding activity with antigens. These sequence analysis showed that all of the heavy chain Fd gene and light chain gene were derived from human immunoglobulin variable region. The light chain variable region of the monoclonal 48 was homologous to the immunoglobulin light chain Vλ homology of 94.4%, and the heavy chain variable region of the monoclonal 48 was homologous to the immunoglobulin heavy Fd chain VH4 homology of 88.9%. The light chain variable region of the monoclonal 56 was homologous to the immunoglobulin light chain Vλ homology of 95.6%, and the heavy chain variable region of the monoclonal 56 was homologous to the immunoglobulin heavy Fd chain VH3 homology of 84.6%. Conclusion We have successfully selected TRAb (TSAb, TBAb) Fab fragment from a human phage display immune antibody library.

OBJECTIVE: This study was designed to develop a rating scale of quality of life (QOL) which fits laryngeal cancer patients after laryngectomy. METHOD: The item pool was developed on the definition of QOL from WHO and the principles and procedures of ddveloping a rating scale. Five methods had been used in the item selection including, such as subjective evaluation methods, discrete tendency, correlation coefficient method, stepwise regression analysis, and factor analysis. The survey was conducted in 126 laryngeal cancer patients after laryngectomy in order to assess the reliability and validity of the rating scale. RESULT: (1) A rating scale of QOL which fits laryngeal cancer patients after laryngectomy including six domains and 27 items is was developed. (2) The split-half reliability coefficient of the scale is 0.802, and the Cronbach' α coefficient is 0.794. (3) It is inferred from the correlation analysis that there are strong correlation between items and their own domains; conversely there are weak correlation between items and other domains. Correlation coefficient is 0.731 between total score and self-rating score. CONCLUSION The reliability and validity of the rating scale is proved to work well.

Objective To master iodine intake ways of children in Yancheng (coastal) and Zhenjiang (inland) cities,analyze their urinary iodine difference and provide solid evidence for adjustment of salt iodine and adequate iodine intake level of local residents.Methods Totally 50％ counties were randomly selected in Yancheng and Zhenjiang cities and 5 towns were sampled in each county in 2014,local water iodine,domestic salt iodine,local eating habits and urine iodine of children 8-10 years old were investigated,and the influences of different iodine intake ways on urine iodine level were analyzed.Results The median of water iodine was 4.76 μg/Lin Zhenjiang (n =40) and 50.80 μg/L in Yancheng (n =50),the difference was statisticelly significant in two cities (Z =6.93,P ＜ 0.05).Totally 2 400 salt samples were tested,the mean of salt iodine was (24.20 ± 5.07) mg/kg in Yancheng (n =1 500) and (22.87 ± 2.77) mg/kg in Zhenjiang (n =900),the difference was statisticelly significant in two cityies (t =7.23,P ＜ 0.05).The salt intake level in Zhenjiang (10.69-± 9.00) g/d appeared to be higher than that in Yancheng (8.40 ± 3.57) g/d,but the difference was not statistically significant (t =1.62,P ＞ 0.05).Totally 1 200urine samples were tested,the urine iodine level of Zhenjiang got higher results (265.83 μg/L,n =450) than that of Yancheng (182.15 μg/L,n =750,Z =12.18,P ＜ 0.05).The ratio of water iodine intake/salt iodine intake was about 1 ∶ 4 in Yancheng and 1 ∶ 50 in Zhenjiang,while residents in Zhenjiang got 21％ of daily iodine through extra ways.Eating habits like eating out did not have significant impact on urine iodine.Conclusions Based on the water iodine level,Yancheng is considered to be a appropriate iodine level area while Zhenjiang is a lack region.However,Zhenjiang has a higher urine iodine level than Yancheng,which is more than adequate to the recommendation.Salt iodine is a main iodine source in both cities.In iodine appropriate and deficiency areas,eating habits and food choices may play a more important role than geochemical factors in iodine intakes among residents.

Objective To explore the application effect of PDCA cycles on the normal limb position of stroke patients with hemiplegia. Methods The stroke patients with hemiplegia (128 cases) were selected as study subjects. Patients(62 cases)during January to September 2014 were set as the control group,and received routine nursing care. Patients(66 cases)during October 2014 to July 2015 were set as the experimental group,and used PDCA cycles management on the normal limb position additionally. The application effect of PDCA cycles on the normal limb position was evaluated through comparing two groups with qualification rates of normal limb position and incidence of complications. Results The qualification rates of normal limb position in the control group was 38.71%(24/62), which was higher than that of the control group, which was 75.76% (50/66) (χ2=16.504, P<0.01). The complications occurred in the control group were strephenopodia (11 cases), foot drop (16 cases), dislocation of shoulder (9 cases), omodynia (27 cases) and myospasm (34 cases), and they were 3 cases, 7 cases, 2 cases, 15 cases and 18 cases in the experimental group respectively. The incidence of complications was lower than those of the control group (χ2=4.001-8.961, P < 0.05), and the difference was statistically significant between two groups. Conclusions PDCA cycles management could improve the qualification rates of normal limb position and reduce the incidence of complications, which was beneficial to the recovery of limb function.

Objective To analyze the clinical significance and correlation factors influencing the serum levels of CA125 and CA199 in patients with chronic nephropathy.Methods Clinical data of 649 hospitalized patients with chronic nephropathy from Jan.to Dec.in 2007 were retrospectively analyzed.The criteria of enrolment were: patients with chronic nephropathy aged below 70 years,tumor excluded by CT and ultrasound,and virus hepatitis and tuberculosis excluded by microbiological examinations.The serum levels of CA125,CA199,albumin,total cholesterol(TC),triglyceride(TG),24h urine protein and urine creatinine(Cr) were determined.The patients were divided into CA125/CA199 positive group and negative group according to the cutoff value of serum CA125 and CA199,and the clinical differences were analyzed by t or ?2 test.The correlation factors influencing the serum levels of CA125 and CA199 were analyzed by multiplicity.Results The ratio of female,nephrotic syndrome(NS),membranous nephropathy(MN) and hydrops of serous cavity were significantly higher in CA125/CA199 negative group than that in positive group(P

Objective To investigate the iodine nutritional status of the crowd that did not participate in the iodine deficiency disorders (IDD) survey in iodine deficiency areas in Jiangsu Province so as to provide a basis for prevention and control of IDD.Methods Eight to ten years old children were chosen from the counties(cities,districts) of Jiangsu Province that did not participate in the IDD survey and urine samples of students and salt samples of their families were researched.In each county (city,district) one township (street) was selected according to 5 directions of east,south,west,north,center; in each township one primary school was selected and in each primary school 20 children aged 8-10 were chosen half of the male and female,to collect their urine samples and salt samples at their families.Urinary iodine was measured using arsenic cerium catalytic spectrophotometric method (WS/T 107-2006),and salt iodine was measured using direct titration of universal test method in salt industry (GB/T 13025.7-1999).Iodine nutrition criterion of international health organization recommended staindard:children urinary iodine ＜ 100 μg/L as iodine deficiency,100-199 μg/L as iodine appropriate,200-299 μg/L as iodine more than appropriate,≥ 300 μg/L as iodine excess.Results A total of 7 523 urinary samples of 8-10 years old children were collected from 76 iodine deficiency counties (cities,districts),and the median of urinary iodine was 235.0 μg/L.In all investigated counties (cities,districts),the medians of urinary iodine of 22 counties(cities,districts) were 100-199 μg/L,42 counties(cities,districts) were 200-299 μg/L,and 12 counties (cities,districts) were ≥300 μg/L.A total of 7 523 salt samples were collected,and the median of salt iodine was 29.68 mg/kg; Taizhou City had the highest salt iodine median,which was 31.43 mg/kg; and Lianyungang City,the lowest,25.11 mg/kg.The coverage rate of iodized salt was 98.6％(7 417/7 523); iodized salt qualification rate was 98.6％ (7 312/7 417); and consuming rate of qualified iodized salt was 97.2％(7 312/7 523) in 76 iodine deficiency counties (cities,districts).Conclusions The progress in prevention and control of IDD in iodine-deficient areas that did not participate in IDD survey in the past is good in Jiangsu Province; the overall level of iodine nutrition of whole population is adequate.But the median of urinary iodine in some counties (cities,districts) is at a higher level.

ObjectiveTo observe the changes in TSH receptor antibody (TRAb) and soluble intercellular adhesion molecule-1 ( sICAM-1 ) levels after treatment of propylthiouracil ( PTU ) and methimazole( MMI ) in patients with Graves' disease (GD). MethodsOne hundred and six cases of clinically diagnosed patients with GD were divided into PTU and MMI groups( each group, n =53 ). The patients in two groups were regularly followed for 36 months. TRAb and sICAM-1 were measured with ELISA method. Results( 1 ) The general data of two groups were not significantly different before treatment( all P＞0. 05 ). ( 2 ) There was no difference in TRAb positive rates between two groups before treatment. The clinical remission rates between PTU and MMI groups showed no difference (83.02％ vs88.68％ ). The cure rate was higher in MMI group than in PTU group( 58.49％ vs 37.74％, P＜ 0. 05 ). (3) There existed significant differences in TRAb levels determined before and 6, 12, 24,30, and 36 months after treatment( all P＜0. 01 ), being gradually decreased with time( F=275.48 ,P＜0.01 ). TRAb levels between two groups were significantly different( F=5.86, P＜0. 05 ). (4) sICAM-1 levels at 36 months after treatment compared with the baseline in both groups were statistically different (P＜0. 01 ), but no difference was found between two groups.ConclusionsBoth PTU and MMI improve the immune status of patients with GD,and the immunosuppressive effect of methimazole is more evident.
