Objective To observe the effect of asarone injection on terms of airway inflammation factor in asthmatic children.(Metho)ds Sixty asthmatic children were chosen and divided randomly into methotrexate group and control group.In the methotrexate group,intravenous injection with 2 times per day was given.The concentration of the injection solution was 0.01%,which was mixed by(0.5 mg/kg) asarone injection and 10% glucose injection.In control group,intravenous injection once per day was given.The solution consisted of 4-6 mg/kg aminophyline injection and 100 mL 5% glucose injection.Every 7 continuous days was taken as one process stage.Two process stages were observed during the experiments.Results After two weeks,the eosinophils and the macrophage were changed significantly(P

Objective To study the clinic features and prognosis of juvenile rheumatoid arthritis (JRA)-associated iridocyclitis.Methods Ten cases of JRA -associated iridocyclitis choosed from 107 cases with JRA were reviewed and analysed.Results Polyarticular( n =9) and pauciarticular( n =1) were observed among JRA -associated iridocyclitis.Four were acute cases and all were recovered.Secondary glaucoma ( n =1) and ablepsia( n =1) were find in the chronic cases of 6,respectively.Conclusions Iridocyclitis is a common complication of JRA. Most of them are polyarticular group. The acute cases have better results compared to the chronic cases which often have more complications such as glaucoma,cataract, et al .

Recombinant plasmids pHY-PA, pBBR-PA were constructed in which genes pdc and adhB were placed under the control of tac promoter, respectively, and had successfully expressed in Escherichia coli. Then these recombinant plasmids were electroporated into Lactobacillus strains for ethanol production. Preliminary ethanol fermentation using these Lactobacillus strains and their recombinants was carried out using 42℃ as fermentation temperature. The results indicated that introducing pdc and adhB, ethanologenic pathway was successfully constructed in L.plantanum CICIM B0080. 0.4% (V/V) ethanol was detected at the end of fermentation with 6.7% glucose, and that is 67-fold as the wild-type B0080. Two-fold of ethanol production was detected in L.amylovorus B0112 (pHY-PA) and L.acidophilus B0068 (pBBR-PA). Introducing both pdc and adhB, and meanwhile knock-outing the lactate dehydrogrnase gene may better convert carbon flux to ethanologenic direction.

Objective: To revise Frost's Multidimensional Perfectionism Scale (FMPS) within a sample of Chinese college students based on clinical knowledge and Hewitt & Flett's perfectionism questionnaire.Methods:Three hundred and fifty college students responded to the inventory with additional 15 items to the FMPS. Exploratory factor analysis was applied to the data. Results: The revised Perfectionism Scale consisted of 50 items, four subscales (Concerns with Mistakes and Doubts, Personal Standards, Organization, Parents' Expectation and Control). Factor analysis indicated that, the four factors explain 42.31% of the variance with loading between 0.37~0.79. The five subscales had internal consistencies with split-half reliabilities 0.73~0.88, Cronbach's alphas 0.80~ 0.91, and test-retest reliabilities of 0.68~0.80 (P

Lysins are efficient bacteria cell wall digesting enzymes encoded by DNA bacteriophage. Gram-positive bacteriophage lysins feature similar domain structure, high lytic efficiency, synergic antibacterial effect with antibiotics, rare neutralization by antibodies, less chance of developing drug-resistant strains, et al. The past decade has seen a considerable amount of research worldwidely focused on lysin, and lysins have been used successfully in a variety of animal models to control pathogenic antibiotic resistant bacteria found on mucosal surfaces and infected tissues. The great potential of lysins as an anti-infective agent prompted this review.

Angiogenesis involves the occurrence and development of serious diseases such as cardiovascular and cerebrovascular diseases and malignant tumors. Promoting or inhibiting angiogenesis is considered to be a key factor in controlling the progression of the disease. Chinese materia medica (CMM) has become a research hotspot because of its good clinical therapeutic effect and significant intervention on angiogenesis. The zebrafish model as an ideal animal model also provides a good experimental basis for the study of angiogenesis. CMM monomers, extracts, prescriptions and Chinese patent medicine, and other forms of intervention were selected as the research object. Based on zebrafish animal model experiments, we summarize domestic and foreign relevant research and review the research progress of the effect of CMM on angiogenesis in zebrafish, aiming to provide reference for further development and application of zebrafish as a model and further study of CMM intervention in angiogenesis.

To determine the number average molecular mass of chitosan-oligosaccharide by u-sing the acetylacetone's method based on the color-producing reaction with amino terminal . Via the tests on the repetitiveness, accuracy and the stability, supposed this method was reliable. At the same time, the contrastive results of HPLC and the traditional K3Fe(CN)6 method indicate that the acetylacetone method was more suitable for the determination of chitosan-oligosaccharide molecular mass.

Objective:To investigate the relationship between college students' perfectionism and their mental health,and parental rearing styles.Methods:The present study was a cross-sectional design.Three hundred and thirty seven Chinese college students(152 males and 185 females;aged 16～24) were recruited through cluster sampling.Participants were from three major universities,and responded to the revised Perfectionism Scale for Chinese College Students,Egna Minnen av Barndoms Uppfostran(EMBU),and SCL-90.Results:The group with high score in perfectionism also got higher scores in their perception of fathers' over-protection,over-intervention,and refusal/denial than the low score group [(2.4?0.5) vs.(2.0?0.4),(2.2?0.4) vs.(2.0?0.3),(1.5?0.5) vs.(1.4?0.5);P
