Objective To discuss the effects of personality features on psychological status of patients with lung cancer in perioperative period.Methods Choosing 97 patients from the thoracic department of the second Xiangya Hospital of Central South University as the study objects.The general information,psychological status and personality features were investigated by using the self-made General Information Questionnaire,Eysenck Personality Questionnaire( EPQ),Self-rating Depression Scale (SDS),Self-rating Anxiety Scale(SAS) and Self-rating Symptom Scale(SCL-90).Results The scores of seven factors including total scores( 153.28±41.98),somatization ( 1.78 ± 0.42 ),compulsion ( 1.96 ± 0.52 ),depression ( 1.77 ± 0.67 ),anxiety ( 1.82 ± 0.56 ),hostility ( 1.68 ± 0.87 ),panic ( 1.44 ± 0.75 ) and psychosis ( 1.56 ± 0.51 ) in SCL-90 were higher than domestic norm (P ＜ 0.05 ).The score of EPQ-P(Psychoticism) ( 10.96 ± 2.65 ) were higher than the domestic norm ( 5.84 ± 3.27 )(P＜0.001 ),and EPQ-N(neuroticism) and EPQ-P were positively correlated with the scores of seven factors in SCL-90.Conclusion The mental status of patients with lung cancer in perioperative period is poor.Solitude and uncaring others are the features of personality,which is correlated with psychological status,and EPQ-E (introvertion-extroversion) and EPQ-N can predict the happening of negative psychology.

To explore the potential of lipoteichoic acid (LTA) induced cardioprotection against ischemia-reperfusion (I/R) injury in isolated rat hearts and whether endogenous nitric oxide (NO) participates in the protection, the rats were pretreated with LTA (1 mg/kg, i.p.) 24 h before the experiment, and the isolated hearts were subjected to 30 min no-flow normothermic global ischemia and 60 min reperfusion after a 20-min stabilization period by the langendorff method. Cardiac functions were evaluated at the end of stabilization, and at 30 min, 60 min of reperfusion. The amounts of MB isoenzyme of creatine kinase (CK-MB), lactate dehydrogenase(LDH) and total NO oxidation products in the coronary effluent were measured spectrophotometrically at the end of reperfusion. It was revealed that pretreatment with LTA could significantly improve the recovery of cardiac function, reduce the release of CK-MB and LDH, and increase the concentrations of NO in coronary effluent. The protective effects were abrogated by pretreatment of the rats with L-NAME. It was concluded that LTA could induce the delayed cardioprotection against I/R injury, and endogenous NO may be involved in the mechanisms.

Background Dibutyl phthalate (DBP) is a common plasticizer in daily life and has been proved to be related to the exacerbation of allergic asthma. Domestic and foreign studies have shown that lipid peroxidation is closely related to the severity of asthma, which can be used as a basis for the diagnosis and treatment of asthma. Whether DBP can induce lipid peroxidation in allergic asthma remains to be further studied. Objective To investigate whether DBP aggravates allergic asthma by inducing lipid peroxidation in allergic asthma mice. Methods Eighty male BALB/c mice were randomly divided into 4 groups, namely control group, DBP group (40 mg·kg⁻¹), 50 μg ovalbumin (OVA) group (allergic asthma model group), and DBP+OVA group. The DBP group and the DBP+OVA group were given DBP by gavage from Day 1 to 28, and the OVA group and the DBP+OVA group were sensitized by intraperitoneal injection of OVA, once every 3 d, a total of 5 injections, from Day 9 to 21. From Day 29 to 35, the OVA group and the DBP+OVA group were challenged by OVA atomization. After the exposure, samples of blood and lung were collected. The airway hyperresponsiveness of mice was observed by lung function analysis. The serum contents of immunoglobulin E (IgE), OVA-specific immunoglobulin E (OVA-IgE), and lung homogenate levels of interleukin 4 (IL-4) were detected by enzyme-linked immunosorbent assay (ELISA) to evaluate airway allergic inflammation. The pathological changes of lung tissues were observed after hematoxylin-eosin (HE) staining and collagen fiber (Masson) staining. The contents of reactive oxygen species (ROS), lipid ROS, glutathione peroxidase 4 (GPX4), reduced glutathione (GSH), malondialdehyde (MDA), and 4-hydroxynonenal (4-HNE) in lung homogenates were detected by ELISA to evaluate lipid peroxidation. Results The results of lung function analysis showed that compared with the control group, the inspiratory resistance (Ri) and expiratory resistance (Re) of the OVA group and the DBP+OVA group were increased, and the lung compliance (Cldyn) was decreased. The DBP + OVA group was more severe, and the difference between the OVA group and the DBP + OVA group was statistically significant (P<0.05 or P<0.01). Compared with the control group, the contents of IgE, OVA-IgE, and IL-4 in the OVA group and the DBP+OVA group were increased (P<0.05 or P<0.01), which indicated more severe allergic airway inflammation. The HE sections of the OVA group and the DBP+OVA group showed inflammatory cell infiltration around the airway, airway wall hyperplasia and thickening, and severe airway deformation, and the presentation of the DBP+OVA group was the most serious. After Masson staining, the OVA group and the DBP+OVA group showed depositions of a large number of collagen fibers, and the blue collagen fibrosis in the DBP+OVA group was even more serious. ROS, lipid ROS, MDA, and 4-HNE levels increased and GSH and GPX4 levels decreased in the OVA and DBP+OVA groups (P<0.05 or P<0.01), with the most severe effect in the DBP+OVA group. Conclusion DBP may induce lipid peroxidation in mice allergic asthma by producing excessive ROS which may aggravate the allergic asthma in mice.

OBJECTIVETo study the association between two single nucleotide polymorphisms (rs4810485 and rs1535045 in CD40 gene) and Kawasaki disease (KD) in Han Chinese children.

METHODSA case-control study was performed on 184 children with KD and 206 normal controls. The polymorphisms of two SNPs in CD40 gene were detected using PCR-RFLP.

RESULTSThere were no significant differences in the genotype distribution and allele frequency of SNP rs4810485 in CD40 gene between the KD and normal groups (P>0.05). The genotype distribution of SNP rs1535045 in CD40 gene in the KD group was significantly different from the control group (P<0.05). T allele of SNP rs1535045 was shown as a risk factor for development of KD (OR=1.592, 95%CI: 1.182-2.144, P=0.004). There were no association between the polymorphisms of the two SNPs and coronary artery lesions (P>0.05).

CONCLUSIONSSNP rs1535045 may be associated with the development of KD in Han Chinese children, while SNP rs4810485 may not.

OBJECTIVETo investigate the association of two single-nucleotide polymorphisms (SNPs) in IL1R1 gene (rs1558641 and rs949963) with the susceptibility to asthma in children from Central China.

METHODSA case-control study was performed in the asthma group and the control group, consisting of 208 children with asthma and 223 normal children from Central China, respectively. The genotypes of two SNPs in IL1R1 gene, rs1558641 and rs949963, were identified using polymerase chain reaction-restriction fragment length polymorphism. The serum level of IL1R1 was determined by enzyme-linked immunosorbent assay.

RESULTSThere were no significant differences in genotype and allele frequencies of rs1558641 between the asthma and control groups. In terms of rs949963, the frequencies of GG genotype and alleles were significantly higher in the asthma group than in the control group (P<0.05). The asthma group had a significantly higher serum level of IL1R1 than the control group (P=0.011). Moreover, the serum level of IL1R1 was significantly higher in patients with GG genotype than in those with AA or AG genotype for rs949963 (P=0.028).

CONCLUSIONSIL1R1 SNP rs949963 is associated with the susceptibility to asthma in children from Central China and may increase the serum expression of IL1R1.

OBJECTIVETo investigate the effect of tetrandrine (Tet) on the expression of bax, bcl-2, and transforming growth factor-β2 (TGF-β2) mRNA in cultured human fibroblasts of Tenon's capsules (TCFS) and explore its possible mechanism.

METHODSThe third passage of TCFS cultured in vitro were exposed to 1×10(-5) mol/L Tet for 24 h, and real-time fluorescence quantitative PCR was used to detect the changes in the expressions of bax, bcl-2, and TGF-β2 mRNA.

RESULTSThe expression level of bax mRNA was obviously higher, while bcl-2 and TGF-β2 mRNA levels were significantly lower in Tet-treated TCFS than those in the control cells (P<0.05).

CONCLUSIONTet can inhibit the proliferation of TCFS possibly by reducing the expressions of bcl-2 and TGF-β2 mRNA, enhancing the expression of bax mRNA and inducing cell apoptosis, suggesting its potential in preventing fibrous scar formation after glaucoma filtration surgery.
