In recent years,zebrafish has become ideal animal models of human disease with its unique characteristics,such as small body,fecundity,fast development and growth,embryo transparency,and so on.Furthermore,the structure and gene of zebrafish eye are highly conservative with human eye,which make ophthalmologists to pay close attentions to zebrafish.This review focused on the studies and applications on zebrafish embryonic development of eyes,and also the applications of currently used genetic regulation and editing techniques and tools.

Objective To explore the expression of the nuclear factor -κB (NF-κB) regulating monocyte ehemoactracttive peptide -1 ( MCP-1) in asthma patients, and investigate the effect of seretide, budesonide and vento-lin. Methods 81 asthma patients were randomly divided into seretide therapy group and budesonide and ventolin therapy group. The NF-κB activation in PBMC and the plasma concentrations of MCP-1 were measured by ELISA. ventolin therapy group (1.70±0.39) ng/L of asthma patients were significantly higher than that control group (0.89±0.34) ng/L ( P<0.001 ) ; The plasma MCP-1 level in seretide therapy group ( 66.89±5.62 ) ng/L and in budesonide and ventolin therapy group (73.35±7.52 ) ng/L of asthma patients were also significantly higher than level of seretide therapy group in asthma patients were significantly lower than budesonide and ventolin therapy group (P <0.001 ). Conclusion NF-κB gene and its regulating protein MCP-1 may be involved in asthma. Glucocotios-teroid and beta2 agonists combination may prolong the process of asthma.

ABSTRACT:Many studies show that helminth‐derived molecules can induce immunoregulatory cells to form immune net‐work‐mediated immune ,thereby inhibiting allergic and autoimmune diseases .Helminth parasites can induce immune cell activa‐tion and produce cytokine .And parasites play an inhibitory effect to affect other immune related diseases .However ,the associ‐ation between helminths infections and immune related diseases does not always have an unequivocal outcome .While some hel‐minths infections protect against allergic diseases ,other helminth can exacerbate this immunopathology .

Objective] By sequencing of SSU rRNA gene cloning from Xinjiang cutaneous leishmaniasis pathogen (XJCLP) to provide evidence for identification of the pathogen. [Methods] By PCR assay with primers R222 and R333, the specific fragment had been produced from SSU rRNA gene of XJCLP , L infantum, L tropica and cloned into pGEM ○[KG-6/7]R T Easy vector .The clones were sequenced by the Sanger dideoxy mediated chain termination method, analysis of SSU rRNA gene sequences from XJCLP, L tropica, L infantum with DNASIS. [Results] Sequence analysis showed that the specific fragment of SSU rRNAgene from XJCLP, L infantum,L tropica , were all 394 bp in length. There were 391 bases identical and three point mutations between the sequences of XJCLP and L tropica , the similarity being 99 2%; 390 bases identical and three point mutations and one insertion /deletion between the sequences of XJCLP and L infantum , the similarity being 99 0%. One insertion/deletion between the sequences of L tropica and L infantum , the similarity being 99 7%. The primary and secondary structures of SSU rRNA gene from XJCLP differed from those of L infantum and L tropica .A retrieval from GenBank confirmed that these 394 bp sequence are new gene sequences. [Conclusion]The primary and secondary structures of SSU rRNA gene from XJCLP, L infantum , L tropica were different. 394 bp sequence from SSU rRNA gene of XJCLP is a new gene sequence.

Objective: To explore the prevalence and co-morbidity in depression disorder among children and adolescents in Chengdu City. Methods: Using a one-phase design, 4S8S children and adolescents in grades 1~10 were assessed with the Strength and Difficulty questionnaire (SDQ) and Development and Well-Being Assessment (DAWBA) . A structured interview with verbatim reports was reviewed by clinicians so that information from parents, teachers, and children were combined in a manner that emulated the clinical process. Results: (1) The rate of depressive disorder was 1.2% , and that in girls was much higher than that in boys after 12 years old (2.56% vs. 1.42%) . (2) The rate of depressive disorder increased with age from 0.10% (6~8 years) to 2.59% (≥ 15 years) . (3) The co-morbidity was 40% . The most common comorbidity diagnosis was anxiety disorders (29.1%) and behavior disorders (25.5%) . Conclusion: The prevalence of depressive disorder among children and adolescents in Chengdu is 1.2%. Gender and age may be the related factors. The co-morbidity is common in children and adolescents with depression disorder.

Objective To discuss the method and efficiency of less invasive stabilization system (LISS) in treatment of comminuted tibia[ fractures. Methods A total of 14 patients with comminuted tibial fractures were treated with LISS between January 2005 and July 2006. There were 10 males and four females, at age range of 19-61 years (mean 34 years). Of all, 11 patients were with proximal fractures of tibia and three with distal ones, including six with open fractures and eight with closed ones. The period from injury to operation was 2-13 days. An observation was done on postoperative soft tissue recovery and fracture healing. Results The average period of follow-up was 9.4 months (4-16 mouths). All frac-tures were healed up after average 7.8 months (4-12 months). All incisions were healed up at one stage, with no complications on nerves, blood vessels or soft tissues. The axes of tibia were good, with sound function of knee and ankle joints. Conclusion LISS is characterized by easy operation, minor trauma, high healing rate and low complications in treatment of comminuted tibial fractures.

Objective To explore the changes and the clinical relevance of plasma p-selectin (PS) and vascular endothelial cell function in patients with carotid stenosis (CS) before and after carotid artery stenting (CAS). Methods The plasma levels of PS, yon willebrand (vWF) and endothelin-1 (ET-1) before CAS and 1hour,6 hours,24 hours,2 months after CAS in 67 patients with carotid stenosis and 54 cases of TIA with negative result from cerebral angiography were measured. The patients of the therapy group were further divided into group A and group B according to complexity of CAS. The plasma levels of PS and vWF were determined by enzyme linked immunosorbent assay,and the level of ET-1 was measured by radioimmunoassay. Results The plasma levels of PS,vWF and ET-1 all increased in the patients group after CAS. In the therapy group,the level of PS reached peak value (29.23 ± 6.98) ng/ml 1 hour after CAS, and the levels of vWF and ET-1 reached peak value (119.63 ±16.75) %, (79.71 ± 9.78) ng/L 6 hour after CAS. In therapy group, there was significant difference in the levels of PS and ET-1 between each time points after CAS and before CAS (P<0.05,P <0.01 respectively). There was significant difference in the level of vWF between 1 hour, 6 hours, 24 hours after CAS and before CAS (P < 0.05 orP < 0.01). There was significant difference in tihe levels of PS 1 hour after CAS and ET-1 at 6 hours after CAS (P <0.05) ,and in the level of vWF at 1 hour,6 hours after CAS between control group and therapy group (P <0.01).There was significant difference in the level of vWF at every time point after CAS (P < 0.05 or P < 0.01), and in the level of ET-1 at 1 hour,6 hours,24 hours between A group and B group(P <0.05 or P <0.01). Conclusions PS, vWF and ET-1 were activated to some extent and related to pathological changes degree and complexity of CAS. Monitoring these biological indexes after CAS maybe of great value in predicting risk, evaluating clinical therapy and judging prognosis.
