Influence of Qileng Decoction on Serum Visfatin Level and Degree of Carotid Atherosclerosis in Patients with Cerebral Infarction / 广州中医药大学学报

Objective To observe the influence of Qileng Decoction on the level of serum visfatin and the degree of carotid atherosclerosis in patients with acute atherosclerotic cerebral infarction(AACI). Methods One hundred and eighty AACI patients were classified into non-AACI control group (group A;N = 30), stable carotid atherosclerotic plaques group(group B;N = 75)and unstable carotid atherosclerotic plaques group(group C;N= 75)according to the results of carotid color ultrasonography. The serum visfatin level of the three groups was detected at the time of AACI attack. Group B and group C were separately randomized into conventional treatment subgroup (N = 37)and Qileng Decoction subgroup (N = 38). The conventional treatment subgroup was given basic therapy for AACI including nutrition support and symptomatic treatment , and Qileng Decoction subgroup was treated with Qileng Decoction (mainly composed of Radix Astragali,Rhizoma Sparganii, Fructus Mori,Radix Trichosanthis, Rhizoma Curcumae,Hirudo,and Fructus Aurantii)orally on the basis of treatment for the conventional treatment group. Before treatment and 15,90 and 180 days after treatment,we detected the level of serum visfatin,and measured the carotid intima-media thickness(IMT)and plaque scores(PS). Results (1)At the time of AACI attack,serum visfatin level of group B and group C was significantly higher than that of group A,and the level of serum visfatin of group C was significantly higher than that of group B,the difference being significant (P < 0.05). After treatment,serum visfatin over-expression was improved in both conventional treatment subgroup and Qileng Decoction subgroup of groups B and C at various time points (P< 0.05 compared with that before treatment), and the improvement in Qileng Decoction subgroup was superior to that in conventional treatment subgroup (P < 0.05). (2)At the end of treatment, IMT was improved in conventional treatment subgroup and Qileng Decoction subgroup of groups B and C (P < 0.05 compared with that before treatment), and the improvement in Qileng Decoction subgroup was superior to that in conventional treatment subgroup (P < 0.05). (3) The total effective rate for PS improvement of conventional treatment subgroup in groups B and C was 74.3％,68.6％ respectively,and that of Qileng Decoction subgroup in groups B and C was 94.4％, 91.7％ respectively, indicating that Qileng Decoction subgroup had better effect on improving PS than conventional treatment subgroup(P < 0.05). Conclusion Qileng Decoction exerts certain effect on regulating the over-expression of serum visfatin and improving the degree of carotid atherosclerosis in AACI patients.

Suicide ideation and its influential factors among primary and junior high school students in rural areas of Anhui province / 中华流行病学杂志

Objective To explore the suicide intention and its influential factors among primary and junior high school students in rural areas of Anhui province,in order to provide evidence for early intervention related to mental health problems.Methods All students from 3 junior high and 5 primary schools in Changfeng county of Anhui were recruited as the study subjects using the cluster sampling method.Data were collected by using Children' s Depression Inventory,the Family APGAR Index,the Trait Coping Style Questionnaire,the Children' s Self-Esteem Scale,Social Anxiety Scale for Children,and the Quality of Life Scale.Chi-square test and Logistic regression were used to analyze the suicidal ideation and its influential factors respectively.Results 8.64％ (252/2917) of the studied children had suicidal ideation.Out of them,9.80％ (166/1694) and 7.03％ (86/1223) were left-behind or non-left-behind children.There was statistically significant difference on suicide ideation between the left-behind children and non-left-behind children (P=0.015).Data from the multivariate logistic regression analysis showed that social anxiety and negative coping style were the risk factors for suicidal ideation (P ＜0.05) while better family function and quality of life were the protective factors of suicidal ideation (P＜0.05).Conclusion Suicide ideation was relatively prevalent among rural children in Anhui province.Family,school and society should carry out different kinds of preventive measures to prevent suicide related behaviors in children from this area.

P-selectin gene -2123 polymorphism in children with Henoch-Sch-nlein purpura / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate whether P-selectin gene -2123 polymorphism is associated with the pathogenesis of Henoch-Sch-nlein purpura (HSP) in children.</p><p><b>METHODS</b>Polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) is used to identify the distribution of allele and genotype frequencies of P-selectin gene promoter -2123 polymorphism in 86 children with HSP (including 40 cases of purpura nephritis) and 70 healthy controls.</p><p><b>RESULTS</b>Compared with the healthy controls, the frequencies of GG genotype and G allele of P-selectin promoter -2123 in children with HSP increased significantly (P<0.05). There were no significant differences in P-selectin promoter -2123 genotype and allele frequencies between the patients with and without nephritis.</p><p><b>CONCLUSIONS</b>P-selectin gene promoter -2123 polymorphism appears to be associated with the pathogenesis of HSP in children.</p>

Polarization and immune regulation of TH cells in children with bronchial asthma / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the polarization and immune regulation of TH cells in patients with bronchial asthma.</p><p><b>METHODS</b>Thirty-eight hospitalized children with bronchial asthma (ranging from 4-12 years old) and 29 age-matched healthy children (Control group) were enrolled in this study. Serum IL-2 and IFN-gamma levels were detected using ELISA. The percentage of TH1 and TH2 cells was detected by intracellular staining.</p><p><b>RESULTS</b>The serum levels of IL-2 (15.94 +/- 3.07 microg/L) and IFN-gamma (487.2 +/- 43.6 pg/mL ) in asthmatic patients were significantly lower than those in the Control group (24.73 +/- 4.37 microg/L and 654.07 +/- 14.64 pg/mL respectively; P < 0.01). The percentage of TH1 in asthmatic patients decreased significantly compared with that in the Control group [(11.24 +/- 2.43)% vs (16.67 +/- 2.73)%; P < 0.01]; in contrast, the percentage of TH2 increased compared with that in the Control group [(19.85 +/- 4.46)% vs (16.08 +/- 6.17)%; P < 0.05].</p><p><b>CONCLUSIONS</b>The serum levels of IL-2 and IFN-gamma, and the number of TH1 cells decreased in asthmatic patients. The decreased number of TH1 cells and the ratio of TH1/TH2 suggest an abnormal polarization of TH1 and TH2 cells. The changes may be associated with the inhibition of cellular immune function in asthmatic patients.</p>
