Abnormal reaction in preventive vaccination is the serious adverse reaction happened in regular vaccination. Department of government and producer of vaccines are liable legislatively. In my opinion, relief fund for abnormal reaction should be established to cover the damage of victims and to decrease the risk of government and enterprises.

BACKGROUND:Recombinant human epidermal growth factor has been shown to promote granulation tissue formation and to accelerate the healing of burn wounds, but the antibacterial effect of recombinant human epidermal growth factor is limited. OBJECTIVE:To investigate the effect of nano-silver dressing combined with recombinant human epidermal growth factor gel in treatment of burns and the influence on the scar. METHODS:A total of 76 cases of shal ow II and depth II degree were randomly enrol ed and assigned to two groups. In the study group, recombinant human epidermal growth factor was coated on the surface of the wound, and then covered by nano-silver dressing. In the control group, recombinant human epidermal growth factor was coated on the surface of the wound, and covered by ordinary sterile gauze. The healing time, the positive rate of bacteria, scarring and adverse reactions were compared between the two groups. RESULTS AND CONCLUSION:The wound healing time and the rate of hypertrophic scars after healing were lower in the study group than in the control group (P<0.01). The rate of flat scar was greater in the study group than in the control group after healing (P<0.01). The bacterial positive rate was significantly lower in the study group than in the control group at 7, 14 and 21 days after treatment (P<0.05). No significant difference in incidence of al ergies and local burning sensation was detected between the two groups (P>0.05). These data confirmed that recombinant human epidermal growth factor gel combined with nano-silver dressing in the treatment of burn has good efficacy and accelerates the wound healing, reduces scar formation, and improves aesthetics.

Objective To establish a new approach based on mathematical morphology that can effectively reduce the drifts in functional magnetic resonance imaging (fMRI) signals. Methods Based on investigation of the characteristic of drifted fMRI signals, a mathematical morphology method for baseline drift correction was presented. Results With both simulated data and real fMRI data, the results of the experiment showed that the mathematical morphology method can effectively correct the baseline drifts. Conclusion Both linear and nonlinear drifts can be removed with the proposed method without any statistical model assumption.

Objective To investigate the effect of 3 concentrations of sevoflurane pretreatment on acute lung injury induced by endotoxin in rats. Methods Thirty-six male SD rats were randomly divided into 6 groups:a control group(Group A), a sevoflurane group(Group B), a 3.6% sevoflurane pretreatment group(Group C), a 2.4% Sevoflurane pretreatment group(Group D), a 1.2% sevo sevoflurane pretreatment group(Group E), and lipopolysaccharide (Group F).The rats were killed 6 h after lipopolysaccharide (LPS) or saline injection.Histological examinations of the lung tissues were performed with light microscope. Lung wet/dry weight (W/D) ratio, myeloperoxidase (MPO) activity, and intercellular adhesion molecule 1 (ICAM-1) mRNA expression were assayed. Results Introvenous LPS significantly aggravated lung tissue damage,increased lung W/D ratio, MPO activity, and lung ICAM-1 mRNA expression compared with the control group(P＜0.05). Precondition with 2.4% sevoflurane significantly attenuated the above mentioned changes induced by LPS (P＜0.05). The 3.6% LPS (Group C) significantly attenuated lung tissue damage and decreased MPO activity,lung ICAM-1 mRNA expression compared with the Group F (P＜0.05),but no significant change in lung W/D ratio was seen (P＞0.05). MPO activity was significantly decreased in Group E (P＜0.05), but lung W/D ratio and lung ICAM- 1 mRNA expression had no significant changes (P＞0.05).Conclusion Precondition with 2.4% sevoflurane can reduce LPS induced lung injury in rats. Decreased expression of ICAM-1 and less accumulation of neutrophils were participated in its mechanism.

Objective To investigate the effectiveness of background music in operating room on psychology of patients and medical personnels. Methods A total of 127 patients who would receive selective operation and 65 surgical staff in our hospital were randomly divided into the intervention group and the control group. There were 63 patients and 30 medical personnel in the intervention group, 64 patients and 35 medical personnel in the control group. Routine care was given to all patients, and background music was broadcasted after patients and medical personnels coming into operating room in the intervention group. The blood pressure and heart rate of patients were contrasted, and the anxiety status was evaluated by Self-Rating Anxiety Scales (SAS), Visual Analogue Scale was used to appraise the horror, discomfort and pain between the control group and the intervention group. Results Diastolic pressure and systolic pressure was higher and heart rate was more rapid in the control group than in the intervention group. SAS score of patients and medical personnel was higher in the control group than in the intervention groups, degree of horror, pain and complaint in patients was more apparent in the control group than in the intervention group. Conclusions Background music could release negative emotion and was helpful for stabling the mood of medical personnel and preserving physical and mental health of patients.

Objective To assess the relationship between serum uric acid (SUA)and metabolic syndrome and coronary artery disease(CAD).Methods 232 untreated subjects with essential hypertension were divided into two groups(CAD and no CAD)by coronary angiography.All subjects were free of myocardial infarction,cardiomyopathy,valvular disease, atrial fibrillation,aortic dissection,and renal disease.Results Compared to no CAD group,age,diabetes,triglycerides and SUA in CAD group were higher.There was a significant association between SUA and the severity of CAD (P=0. 015).However,after adjustment for concomitant risk factors of cardiovascular disease,SUA was not an independent risk factor of CAD(P=0.151).In sex-specific analysis,there was a trend of SUA to be an independent risk factor of CAD in women(P=0.062),but it was no statistic significance.The highest quartile level of $UA tended to be associated with increased risk for CAD,but it was not statistically significant either(OR=2.52,P=0.075).SUA was closely associated with metabolic syndrome and diabetes in woman.Conclusion In untreated patients with essential hyperteusion,SUA was associated with metabolic syndrome and the severity of CAD,but it is not an independent risk factor of CAD,the raised SUA may be only a marker of insulin resistance.

Human height, a complex trait with over 80% heritability, is determined by genetic and environment factors. Currently, a certain amount of specific variants about human height have been found, especially with the widely used of genome-wide association studies (GWAS) in genetics research, making it a great progress for the discovering of height associated genes. However, single nucleotide polymorphisms (SNPs) found by GWAS can only explain a minority of the heritable. This article reviews the progress of GWAS about height associated genes and missing heritability domestic and overseas.
