Aim To prepare and identify monodonal sntibody (Mab) specific for Toaoplasma gondii tachyzoites. Method The Mab specific for Taxoplasma gondii tachyrzoite were prepared via bybridoma technique. Indirect ELISA was used to determine the activity of the Mab. Agarose double immuodiffusion test was performed to confirm subclass and SDS-PAGE & western blot were used to analysis rolecular weight of the antigen (s) recognized by the Mab. IFA was used to identify the epitope of Taxoplasma gondii tachyzoites. The protection and specificity of the Mab were snalysed at same time. The Mab was tesed in Mab-ELISA method to detect Taxoplasma gondii antigen. Results A Msb F7C8H12 specific for T. gondii was produced. It belongs to IgG1 subclass. Moleculsr weight of the sntigens recognized by the Mab was 16.5 and 24 kDa. IFA did not show fiuorescence in intact tachyzoite.Inhibition test showed that the inhibition rate was 50% when the concetration of the antigen was 40μg/ml.Afterthe RH strain tachyzoites were incubated with Mab ascites, mice were inected with the tachyzoites through peritoneum. The results showed that the mean dead time of mice were not delayed. T. gondii antigen mixed with PBS snd normal human serum was detected by Mab-ELISA, the sensitvity was 0.78 yg/ml and 1.5μg/ml respectively. When mice were infected with T. gondiiRH strain tachyzoites, 103/mouse p.i., circulating antigen could be detectedin 6 day and 8 day. Conchusion The Mab (F7C8H12) to T. gomdii tachyzoites is an excellent probe for studying T. gondii snd toxoplasmosis.

The circulating antigens of Schistosoma japonicum and the antibodies against the worm in the sera of patients were detected concurrently by Dot-ELISA.In 30 sera from patients with acute schistosomiasis, 51 sera from patients with chronic schistosomiasis and 30 sera from patients being treated by praziquantel 5=6 years ago, the positive rates of the circulating antigens were 86.7%, 78.4% and 23.3% respectively, but all negative in 30 sera from patients with clonorchiasis sinensis. One of the 40 sera from healthy individuals had a weak positive reaction. The positive rates of the antibodies in those acute, chronic and treated patients with schistosomiasis were 100.0%,96.1% and 30.0%; the mean titers of antibodies were 1 : 367.6, 1 : 181.7 and 1 : 9.8 respectively; Two sera from patients with clonorchiasis were positive. All of the healthy individuals were negative.The results indicaded that the circulating antigen was in accord with the antibodies in most sera from schistosomiasis patients.

This study reported the primary application of FA-ELISA from 107-121kDa fration antibody of Schistosoma Japonicum for detection of the short-term antibody in patients with schistosomiasis. The result showed that this method provided high sensitivity (with positive rate of 93. 33% with 30 cases of schistosomiasis) and good specificity (no false postive in 60 health objects). When one group of schistosome patients were examined with FA -ELISA and with the routine SEA-ELISA before chemotherapy and at 8 months,1 year and 1. 5 year after treatment,it showed good property for evaluation of chemotherapy efficacy with FA -ELISA,which was much better than the routine method.

Objective To investigate the suitable mode of cognitive-behavioral therapy for lung transplant recipients during waiting for lung and evaluate the effect to improve patients' physical and mental state.Methods 50 cases were randomly divided into the experimental group and the control group,each group with 25 cases.The control group received conventional treatment.The experimental group received cognitive-behavioral therapy in addition to conventional treatment.SAS and vital signs were measured in the two groups on admission,2 weeks and 4 weeks after admission.Results The SAS score of the experimental group was lower than the control group 2 weeks and 4 weeks after admission and SAS score decreased as the intervention extended.The SBp of the experimental group was lower than the control group 4 weeks after admission.There was no significant difference of DBp between two groups.The heart rate of the experimental group was lower than the control group 4 weeks after admission.The heart rate of the experimental group was lower on 2 weeks and 4 weeks after admission than on admission.4weeks after admission,the respiratory rate of the experimental group was lower than the control group and on admission.Conclusions Cognitive-behavioral therapy can reduce the level of anxiety and keep vital signs stable with good feasibility and effectiveness.

Objective:To explore influence of health education on quality of life and compliance in community pa‐tients with coronary heart disease (CHD) .Methods :A total of 83 community CHD patients were selected and ran‐domly divided into routine treatment group (n=38 ,received routine treatment of CHD ) and health education group (n=45 ,received CHD health education based on routine treatment ) .Score of Seattle angina questionnaire (SAQ) after intervention ,therapeutic compliance and incidence rate of major adverse cardiovascular events (MACE) with‐in six months were compared between two groups .Results:Compared with routine treatment group after interven‐tion ,there were significant rise in each item score and total score of SAQ [total score ,(54.3 ± 7.2) scores vs .(65.4 ± 7.5) scores] ,P<0.05 all;and therapeutic compliance also significantly rose (good rate ,52.6% vs .77.8% ) in health education group , P< 0.05. After six‐month follow‐up ,total incidence rate of MACE in health education group was significantly lower than that of routine treatment group (8.9% vs .26.3% ) , P< 0.05. Conclusion:Health education can significantly improve quality of life ,compliance and prognosis in community patients with cor‐onary heart disease ,which is worth clinical extending and use .

Objective The incidence rate of pressure ulcer is high in critical patients and off-loading mattresses and reposi-tioning are known as effective interventions for the prevention of pressure ulcers .However, evidence is lacking for selection of the right type of mattresses and suitable interval of repositioning .This study was to compare the effects of two types of off-loading mattresses with two different repositioning intervals in preventing pressure ulcers in critical patients . Methods According to the design of this ran-domized controlled trial , we made a training plan concerning the participants , methods of intervention and comparison , criteria and methods of observation , and methods of recording , and trained 26 nurses from 7 hospitals .Using non-inferiority design and the method of stratified blocked randomization , we divided 1194 patients with the risk of pressure ulcer into a trial group ( n=596) and a control group ( n=598) , a viscoelastic sponge mattress with every-four-hours repositioning used for the former and an automatic aeration mat-tress with every-two-hours repositioning for the latter , both for 7 successive days .We examined the patients every day , recorded the in-cidence and stages of pressure ulcer , and compared the data obtained between the two groups of patients . Results The total inci-dence rate of pressure ulcer was 1.09%(13/1194), significantly lower in the trial than in the control group (0.34%[2/596] vs 1.84%[11/598], P=0.012). Conclusion A viscoelastic sponge mattress with every-four-hours repositioning is superior to an automatic aeration mattress with every-two-hours repositioning and therefore is preferred to the latter in preventing the incidence of pressure ulcer in critical patients in the ICU .

AIM: To study the characterization of thyrotropin receptor (TSHR) and its active fragment TSHR aa352-366 as immunogens in BALB/c mice. METHODS: BALB/c mice were injected peritoneally with TSHR aa352-366-KLH (hemocyanin from keyhole limpets) and the mixture of TSHR aa352-366-KLH and guinea pig TSHR every 15 days, respectively. The levels of thyroid hormones and TSHR antibodies and TSHR mRNA were measured, and the pathological changes of thyroid tissue were observed. RESULTS: In the group injected with TSHR aa352-366-KLH, the serum levels of TT_3 and TT_4 decreased (P
