Objective To investigate the optimal mild hypothermia course and cerebral temperature of the neonatal rats after hypoxic-ischemic brain injury. Methods The posthypoxic-ischemic rats of experimental group (n=60) were placed in the glass jars immeresd in water bath held constaut at either 29 C or 3l C for 24h, 48h or 72h. While the rats of room temperature group (n=22) were stayed in room air. Blood glucose, blood gases and neuropathology findings were studied to determine the therapeutic effects. Results The brain temperature droped 3C or 5C when enviro ment temperature was 31C or 29C respectively. The blood glucose remained normal. Neuropathology findings reveled that the brain damage of experimental rats reduced 46%~86% compared to the room temperature group. Conclusion Reducing the cerebral temperature by 4~5 C for 72 hours after hypoxic-ischemic brain injury can lead to superior protective effect.

Objective To investigate the impact of health education and standard treatments on the life quality of asthmatic children.Methods We conducted clinic treatments of 110 cases of asthmatic children lasting for 6 months,which were divided into standard treatment and health education group with 60 cases and group without standard treatment and health education with 50 cases.We emphasized the education management on cases in experimental group,which strictly obeyed the Global Initiative for Asthma (GINA) to formulate classified treatments as well as regular follow-up.Control group received the same treatments as experimental group yet without emphasizing health education about asthma on parents,which was accompanied with irregular follow-up.We compared the before-treatment and after-treatment life-quality and lung functions of asthmatic children.Moreover,we used Pediatric Asthma Quality of Life Questionnaire (PAQLQ) to evaluate the before-treatment and after-treatment life quality of asthmatic children.Results After follow-up lasting for 6 months,the treatments of experiment group had obvious improvements (P <0.01).The improvements of peak expiratory flow (PEF) of lung function test and timed vital capacity of the first second (FEV1) of experimental group were also better than the improvements of these two metrics of control group (P < 0.01).In addition,after 6 months,in both all dimensions of PAQLQ and total score,the differences between before and after treatment of experimental group were significant (P < 0.01,P < 0.05) ; and the differences between experimental group and control group were also significant in both all dimensions of PAQLQ score (12.4 ±2.1) and total score comparing to the control group (8.1 ±2.3),and the differences are also significant (t =2.5,P < 0.01).Conclusions Health education and standard treatments significantly improved the life quality of asthmatic children with a good compliance of treatment and a low recurrence rate,which is worth of popularizing.

AIM: To investigate two single nucleotide polymorphisms (SNP) in the apolipoprotein(a) promoter at positions -418 and -384 and to compare distributing difference of genotype frequencies of single nucleotide among different races and to explore the influencies of them on serum lipid level and their association with coronary heart disease (CHD). METHODS: Using PCR-RFLP (BsgI,BfaI) method, we determined genotypes of these two SNPs in 156 unrelated healthy controls of HanZu Chinese and 56 unrelated CHD patients of HanZu Chinese and 56 unrelated African Blacks, then cloned polymerase chain reaction (PCR) products into T-vector and sequenced it by M13 currency primer, correspondingly. RESULTS: (1) There was no polymorphism at position -418A/A and -384C/C in control group. Only one CHD patient′s genotype determined was -418G/G, other were -418A/A and (-384C/C) in CHD patients. (2) Only two African Blacks′ genotype determined was -418G/G, other were -418A/A and (-384C/C) in African Blacks. (3) However, the Apo(a) promoter sequence was in coincident with the sequence publicized in GenBank and the base at positions -418 was adenine (A) and -384 was cytosine (C). CONCLUSION: The mutation frequencies at position -418 and -384 are low in the Chinese Han Population of Hubei and perhaps no single nucleotide polymorphisms is at two positions. No association with serum lipid levels and CHD is observed. There may be great variabilities to the SNPs in the Apo(a) promoter among different races.

Objective To determine the levels and significance of Krebs von den lungen-6(KL-6), pulmonary surfactant protein A (SP-A), SP-D and interleukin (IL)-6 in patients with connective tissue disease interstitial lung disease (CTD-ILD). Methods The serum KL-6, SP-A, SP-D and IL-6 in all subjects were detected and the imaging and pulmonary function were recorded t test, χ2 test, non-parametric test, ANOVA and correlation analysis were used for data analysis. Results ① The levels of serum KL-6, SP-A, SP-D, IL-6 in the CTD-ILD group [551.4 (428.2, 883.5) U/ml, 938.4(435.2, 2324.7) pg/ml, 90.7 (80.7, 100.3) ng/ml and 30.4 (22.9, 41.7) pg/ml; P all<0.05] was significantly higher than that in the CTD group [192.9 (139.2, 266.2) U/ml; 458.0 (372.6, 529.0) pg/ml; 80.0 (71.2, 98.3) ng/ml; 18.6 (4.9, 31.0) pg/ml, Z=-5.383, -3.76, -2.123,-3.903, P all <0.05]; and higher than healthy controls (n=30) [183.2(141.9, 216.6) U/ml; 229.0(162.0, 248.0) pg/ml;50.8(26.1, 96.4) ng/ml;7.1(3.7, 8.7) pg/ml, Z=-5.801,-8.13, 2.272, 3.266;P all<0.05].②The levels of KL-6 in pulmonary HRCT for active ILD group was significantly higher than the non-active ILD group [998.5 (640.3, 1293.3) U/ml vs 565.0(434.0, 799.5) U/ml, Z=2.182, P=0.023], there was no statistical difference in the levels of SP-A, SP-D, IL-6 between the 2 groups. ③ Spearman correlation analysis showed that KL-6 was negatively correlated with forced vital capacity (FVC%);SP-D, IL-6 and diffusing capacity of carbon monoxide (DLCO %). ④ Logistic multiple regression analysis showed that KL-6 [OR=1.017, P=0.002, 95%CI (1.006, 1.028)], SP-A [OR=1.023, P=0.009, 95%CI (1.006, 1.041)], SP-D [OR=1.175, P=0.009, 95%CI (1.075, 1.264)], IL-6[OR=1.213, P=0.001, 95%CI(1.088, 1.354)] were the risk factors for ILD. Conclusion Serum KL-6, SP-A, SP-D and IL-6 are significantly increased and correlate with CTD-ILD. KL-6 is related to the pulmonary inflammatory disease and vital capacity, while SP-D and IL-6 are related to diffusion function.
