Objective To describe the anxiety of caregivers and condition management of preschool asthma children ,and analyze the relation?ship between anxiety and disease management. Methods A total of 208 caregivers of asthma children from two hospitals in Shanghai were select?ed using convenient sampling,and surveyed by self?rating anxiety scale(SAS),condition management ability scale and condition management diffi?culty scale. Results The score of SAS were negatively correlated with the condition management ability and positively correlated with the condi?tion management difficulty. Hierarchical regression analysis showed that the model explained 26.6%amount and 35.1%amount of variation respec?tively. Conclusion The anxiety of caregiver of children with asthma may affect the disease management. Future interventions should be strength?ened on the caregivers'psychological problems,so as to improve disease management and control asthma more effectively.

Objective: To explore the effect of transgenic metallothionein (MT) mushroom on anti-radiation ability of mice. Method: Dried power of transgenic MT mushroom was mixed into the feed of ICR mice. After being fed for 23 d, they were irradiated by 5.0Gy 60Co-?rays. Then their anti-radiation ability was determined after being fed 7 d again. Results: Transgenic MT mushroom can evidently alleviate the injury of platelet and spleen induced by radiation, and apparently increase SOD activity and reduce MDA content in irradiated mice’s serum. Conclusion: Transgenic MT mushroom can improve anti-oxidation ability of irradiated mice.

Objective To evaluate the diagnostic value of the recombinant protein Sj_Ts4 in immunodiagnosis of Schistosomiasis japonica.Methods Seventy-four blood samples of schistosomiasis japonica patients(acute, chronic and advanced)were used for evaluating the sensitivity.Blood samples from 24 Clonorchiasis patients,8 patients with hookworm infections and 30 normal persons from the areas without Schistosomiasis were used ror patients.Results The positivity rates were 97.1%(33/34),100.0%(16/16),87.5%(21/24)in rSj-Ts4-ELISA and 100%(34/34),100.0%(16/16),75.0%(18/24)in SjAWA-ELISA in acute,chmnic and advanced Schistosomiasis. respectively.Statistical analysis revealed no significant difference in sensitivity(X2=1.23,P>0.05)between both recombinant and crude antigens.The false positive reaction was found to be 6.7%(2/30)in rSj-Ts4-ELISA and 3.3%(1/30)in SjAWA-ELISA when detected in 30 cases of normal control sera.but no statisticallv significant difference was noted(x2=0.35,P>0.05).Twelve point five percent(3/24),20.8%(5/24)and 12.5%(1/8),37.5% (3/8),of cross-reactions were observed between rSj-Ts4-ELISA and SjAWA-ELISA for detecting the sera of patients with clonorehiasis and hookworms.There was no significant difference of cross-reaction in two parasitic infections (x2=0.60,1.33,P>0.05)with the two tests.Conclusions The rSj-Ts4 antigen shows higher sensitivity and specificity for the diagnosis of Schistosomiasis japonica,which is helpful in the serological diagnosis of Schistosomiasis japonica in endemic areas.

The endocytosis/phagocytosis of calcium alginate nanocapsules by peripheral blood derived dendritic cells was confirmed with the use of Quantum dots labeling.Results further demonstrated these nanoparticles could cause the upregulation of HLA-DR expression to induce the maturation of dendritic cells in vitro.Dendritic cells stimulated by nanocapsules covalently loaded with BSA were shown to stimulate the proliferation of self T cells with blank capsules and free BSA as controls,suggesting their potential applications in cancer cell therapy as a new antigen delivery vehicle with a strong adjuvant effect.

Objective To summarize the coronary artery pattem of arterial switch operation(ASO),operative skill and surgical results.Methods Between October 1999 to October 2005,102 patients underwent arterial switch operation.The mean age was(8? 16)months ranged from 3 days to 7 years.The mean body weight was(5.9?3.2)kg,ranged from 2.5 kg to 20.0 kg.Most com- monly(74/102),the aorta was more or less to the right of the pulmonary artery.In 10 patients,the aorta was directly anterior to the pulmonary artery,and in 11 patients,the aorta was to the left of the pulmonary artery.The great arteries were side by side in 7 pa- tients.We used Leiden classification for coronary artery pattern by operative descriptions.The most prevalent coronary pattern [1LCx2R]was found in 69(67.6%),abnormal coronary artery pattern in 33(32.3%).Intramural course of coronary artery was fotmd In three patients.The Leeampte maneuver was used in all cases.In most patients,the "open trap door" or "bay window" tech- nique for coronary osfia transfer.Results Total mortality rate was 14.7 %(15 eases),6 cases(8.7 %)with normal coronary pattem and 9(27.3%)deaths 33 patients with abnormal coronary pattern.3 cases with coronary event occurred in 5 deaths of simple rIGA, 4 cases with coronary event in 6 deaths of complex TGA and 3 eases with coronary event in 4 deaths of Taussing-Bing anomaly.Con- clusion Complex coronary artery anatomy increases the operative risk.With experience or improving surgical technique,we may get better results.

OBJECTIVETo investigate the correct method of bone resection and posterior capsular soft tissue releasing in total knee arthroplasty (TKA) for the patients with rheumatoid arthritis with stiff knee in flexion.
METHODSFrom November 2009 to January 2012,15 patients with rheumatoid arthritis with stiff knee in flexion underwent primary TKA and releasing of the posterior soft tissues. There were 7 males and 8 females,aged 22 to 75 years old (58.7 years old on average). The preoperative range of movement(ROM) was (3.2 ± 1.7)°. According to Knee Society score (KSS) criterion, the preoperative clinical score was 23.3 ± 12.5 and functional score was 35.2 ± 9.8. Based on the correct osteotomy, effective releasing of posterior structures was used for different degrees of flexion contracture during the TKA procedure.
RESULTSAll the patients were followed up, and the average duration was 2.3 years (1.6 to 3 years). At the latest follow-up,the KSS clinical score was 81.7 ± 6.5 and functional score was 82.8 ± 9.3. The flexion and extension ROM of the knee joint was (103.5 ± 13.1). Three knees remained 50 flexion contracture deformity, but the function of the affect knees was good.
CONCLUSIONThe effective releasing of the soft tissue of posterior capsule is a major management for correction of the flexion contracture in TKA. The correct releasing of posterior structure can not only achieve fundamental gap of TKA but also effectively avoid bone over-resection.

Objective To study the mechanism of mesenchymal stem cells immunosupression lym- phocyte proliferation via B7-H1/PD-1 pathway upregnlated by IFN-γ. Methods Bone marrow derived mes-enchymal stem cells (MSC) were isolated and purified by repeat adherent passage and detected them multi-potential differentiation in conditioned culture medium. Then MSC were cocuhured with lymphocyte prolifera-tion and assayed the level using γ H-thymidine incorporation. Meanwhile, ELISA measured IFN-γ, TGF-β, TNF-α and IL-10 in the cocuhured supernaatant and analyzed variation of B7-H1 molecular profile in MSC by flow cytometry. At last siRNA technology was deploied to interfere B7-H1 expression and analyzed MSC im-munosuppression on lymphocyte proliferation. Results In vitro the isolated MSC become homogeneous spi-die-shaped adherent cells after five passages, and in conditioned culture medium they could differentiate into adipocytes, osteocytes and chondrocytes. In the eocuhure of MSC with mixed lymphocyte, lymphocyte prolif- eration stimulated by Con A or by anti-CD3/CD28 antibody. The cpm value of the proliferation detected by 3H thymidine incorporation showed MSC suppressed the proliferation significantly (P = 0. 0167, 0. 0081,<0.0001 ) and the suppressive potential in a dose-dependent fashion. In the coeuhured supernatant cyto-kine IFN-T and TNF-α were detected in high concentration, but TGF-β, IL-10 were undetected. Simultane- ously MSC in the coeuhure upregulated B7-H1 expression from basic expression 7% to higher than 70% ( P < 0.05 ). After interfere B7-H1 expression in MSC by specific siRNA, we detected lymphocyte proliferation and got higher cpm by 3H thymidine incorporation ( P < 0. 05 ). Conclusion MSC upregulated B7-H1 mo-lecular expression upon the stimuli of IFN-γ, and through the B7-H1/PD-1 pathway mediated immunosu-pression on lymphocyte proliferation.
