Methods 26 atopic dermatitis,33 asthma/bronchiolitis,20 allergic purpura, 15 Kawasaki disease patients and 20 normal children were tested total lgE,lgE to food or inhalant allergens,ECP by UniCAP system and compared.Resuits Fx5E positive rate are 73.1%,24.2%,25.0%,13.3%in atopic dermatitis,asthma,allergic purpura,Kawasaki disease respectively,and the Phadiatop positive rate are 23.1%、69.7%、10.0%、6.6%.The serum levels of ECP、TIgE of patients were higher than the mormal controls,with the highest level in asthma, and lowest in Kawasaki disease,the differences were significant(P<0.05).Conclusions Food orinhalant allergens plays an important role in the inflammatory process of asthma,atopic dermatitis,and some role in allergic purpura,Kawasaki disease.Food allergens are more important to atopic dermatitis.and inhalant allergens are more important to asthma.

Objective To analyze the family and clinical characteristics of talking about killing self (TAKS) among children and adolescents and its relationship with social competency.Methods One thousand nine hundred and seventy-five 7-17-year-old students from 12 schools (each four for primary,middle and high schools) of Wuhan area,were approached through multistage random cluster sampling,and administered with a self-designed general information questionnaire and the Chinese version of Children' s Depression Inventory.In addition,subjects' parents completed Achenbach' s Child Behavior Checklist (CBCL).TAKS was judged based on item 91 (talk about killing self) of CBCL.Multiple Logistic Regression was used to identify factors associated with TAKS.Results The half-year prevalence rate (95％ CI) of parent-reported TAKS was 4.1％ (3.2％,5.0％).TAKS was significantly associated with bad marital status of parents (OR=2.29),unemployment of fathers (OR=2.07),frequently jangling between father and mother (OR=2.23),parents ever having fought with each other intensely (OR=2.00),being frequently bullied by classmates (OR=2.11),internal behavior problem (OR=2.28),external behavior problem (OR=2.50) and depressive symptoms (OR=4.83).TAKS subjects had significantly lower social compctency score than non-TAKS subjects((18.8±7.6) vs.(20.9±6.9),P=0.007).Conclusion The prevalence of TAKS is higher among children and adolescents with several disadvantaged family factors,behavior problems and depression.Children and adolescents with TAKS also have worse social competency.More close clinical attention should be paid to such phenomenon.

Since the children were born,their yin-yang balance in their body began.Children’s yin-yang balance is the yang taken a dominant role in yin-yang balance."Shaoyang for the pivot" is the core of "Shaoyang doctrine"theory.It is very proper to explain the children’s yin-yang balance with the state of continuous transporting and changing by the theory of "Shaoyang for the pivot".Along with "mutual promotion of growth between yin and yang",new yin yang balance continuously replace the old one,constructing children’s basic physical characteristic of "full of vigor and vitality,rapid development;viscera is delicate and organs function is not perfect".Meanwhile it is very proper to explain the pathological characteristics "easy incidence,rapid changing;viscera qi clean and full of spiritualism,easy rehabilitation".So "Shaoyang doctrine" can cover "pure yang doctrine" and "immature yin and yang theory".

Objective To explore the relationship between depression and anxiety and peripheral blood cell counts ( white blood cell ( WBC) ,neutrophil ( NEU) ,lymphocyte ( LYM) ,red blood cell ( RBC) and hemoglobin ( HGB) ) of heroin?dependent patients receiving methadone maintenance treatment ( MMT) . Methods Two hundred and fifty?two MMT heroin addicts, who had received peripheral blood tests within the week prior to the study,were administered with a general information questionnaire,SDS and SAS. The results of blood tests of these patients were compared with those of 109 healthy people in physical examina?tion. Multiple linear regression was used to analyze associations between indicators of peripheral blood cell counts and depressive and anxiety symptoms. Results Compared with healthy controls,MMT patients had significantly higher proportions of elevated WBC(14.7%vs 3.7%),NEU(12.7% vs 2.8%) and LYM(9.9%vs 2.8%) counts (all P<0.05),and low RBC(10.3%vs 4.6%) counts and HGB(11.5%vs 4.6%) concentra?tion (both P<0.05). Multivariate linear regression analysis showed that blood cell counts of WBC ( β=0.261, P<0.01),NEU ( β=0.264, P<0.01),LYM ( β=0.196, P=0.003) and RBC ( β=-0.144, P=0.021) were independently associated with depression;and blood cell counts of WBC ( β=0.298, P<0.01) and LYM ( β=0.269, P<0.01) were independently associated with anxiety. Conclusion Improving the in?flammatory and malnutrition status may be helpful for reducing depressive and anxiety symptoms of MMT her?oin addicts.

Objective:To prepare capsaicin liposomes and study the feasibility by in vitro percutaneous penetration test. Meth-ods:Capsaicin liposomes were prepared by a film-ultrasonic method. The best formula was screened by orthogonal test based on single factor studies with the entrapment efficiency as the index. The improved Franz diffusion cells were used to study the transdermal pene-tration of capsaicin suspensions, capsaicin liposomes and capsaicin ointments, and the cumulative penetration amount through the isola-ted rat skin was compared. Results:The optimal formula of capsaicin liposomes were as follows:the ratio of capsaicin to lipids was 1∶5;the amount of Tween-80 was 100 mg;the amount of vitamin E was 50 mg;10 ml dichloromethane was used as the solvent. The op-timal pH value of the external phase was 6. 5 with the volume of 10 ml. The ultrasonic time was 8 min. The order of 12-hour cumulative penetration amount was capsaicin liposomes>capsaicin-PBS suspensions>capsaicin ointments. Capsaicin liposomes had the highest 12-hour cumulative penetration amount and showed obvious sustained-release property. Conclusion:Capsaicin liposomes have high en-trapment efficiency, good percutaneous penetration and sustained-release property, and the preparation technology is simple.

Objective To investigate the safety of different intensity anticoagulation therapy of warfarin in preventing thromboembolism in octogenarian patients with nonvalvular atrial fibrillation (NVAF). Methods The 130 patients with persistent or permanent NVAF were randomly divided into three groups: low-intensity warfarin group (35 cases, international normalized ratio, INR (1.5-2.0), moderate-intensity warfarin group (32 cases, INR 2.1-2.5) and aspirin control group (63 cases). The rate of hemorrhagic events and the effect on renal function were observed. Results The incidence of hemorrhage was the lowest in low-intensity warfarin group compared to the other groups with slight bleeding in one case. life-threatening bleeding in one case, severe bleeding in one case and slight bleeding in four cases occurred in moderate-intensity warfarin group. Life-threatening bleeding in three cases, severe bleeding in two cases and slight bleeding in six cases occurred in aspirin control group. There were significant differences in bleeding incidence among the three groups (χ2=5.13,P＜0.05). The low-intensity warfarin group and moderate-intensity warfarin group were superior to the aspirin control group in the effect on renal function (P＜0.05). Conclusions It is safe that the dose of warfarin is maintained at low anticoagulation intensity between INR 1.5 and 2.0 in octogenarians with NVAF.

Objective To understand the diagnostic value of blink reflex (BR) in central neuropathy by observing the variations of blink reflex in diabetic patients. Methods Electrical pulse was used to stimulate the supraorbital nerve at the supraorbital notch. The responses of bilateral orbicular muscles of the eye were recorded, the variations of the latency and amplitude of R 1 and R 2 recorded on the side of stimulation and of R′ 2 recorded on the contralateral side were measured. Results There was significant prolongation in the latency and lowering of the amplitude of R 1, R 2 and R′ 2 in the diabetic patients compared with the control group. The abnormality rate of BR increased gradually with the prolongation of diabetic duration. Conclusion BR examination might provide an objective index for nervous damage in diabetic patients and it is helpful in early diagnosis of diabetic neuropathy.

Objective To investigate the expression of RECK gene in placentas of patients with preeclampsia and its correlation with MMP-2 activation,and explore the possible roles of RECK gene in the placental trophoblast invasion mechanism.Methods RT-PCR and Western blot were used to detect the expression of RECK mRNA and protein respectively in the placental tissues of normal late pregnant women (normal pregnant group,22 cases) and pre-eclamptic patients(22 mild cases and 20 severe cases).Gelatinase zymography was used to determine MMP-2 activation ratio.Results The expression levels of RECK mRNA and protein from placenta tissues in mild,severe pre-eclamptic group were both significantly higher than those in nomal pregnant group.Moreover,the expression levels of RECK mRNA and protein in severe pre-eclamptic group were obviously increased as compared with those in mild pre-eclamptic group.There was significant difference among the three groups (all P<0.01).MMP-2 activation ratio in mild,severe pre-eclamptic group was significantly lower than that in normal pregnant group.MMP-2 activation ratio in severe pre-eclamptie groups was obviously reduced as compared with mild pre-eclamptic group.There was significant difference among the three groups(all P<0.01).The expression leVels of RECK mRNA and protein were significantly negatively correlated with MMP-2 activation ratio (both P<0.01).Conclusion The abnormal high expression of RECK and inhibition of MMP-2 activation in placentas of pre-eclamptic patients may participate in the process of placental trophoblast shallow invasion.
