Bronchial asthma is the chronic airway inflammatory disease that characterized by reversible airflow limitation .The presence of airway inflammation could lead to airway remodeling .In recent years , many studies have found that arginase plays an im-portant role in the airway inflammation and airway remodeling of asthma .It not only reduces airway release nitric oxide and increases airway hyperresponsiveness , but also its metabolites such as putrescine , proline, etc can induce cell proliferation and collagen synthe-sis, leading to airway remodeling .In this paper , the arginase and its role in the pathogenesis of asthma are discussed .

Objective:To analyze the correlation of single nucleotide polymorphisms ( SNP) of ATP binding cassette transporter A1 gene (ABCA1) and lower extremity atherosclerotic disease (LEAD). Methods: The clinical data and peripheral blood were col-lected from 630 participants (314 LEAD cases and 316 normal controls) in Han population of Minnan. The 9 SNP genotypes in the ABCA1 gene were detected by Sequenom MassArray. Results:Among the 9 SNP genotypes, rs2980083 was rejected because it wasn' t in accordance with Hardy-Weinberg equilibrium. Obvious linkage disequilibrium was found between rs2066714 and rs2066715, rs1800976 and rs2246293, rs2246293 and rs2980083, and rs1800976 and rs2980083(D′>0. 9,r2 >1/3). There were no significant differences (P>0. 05) in 6 haplotypes of ABCA1 gene groups between the LEAD cases and the normal controls. No significant differ-ences (P>0. 05) were found in frequency distribution between the LEAD cases and the normal controls in 8 SNP according to the re-sults of genotype statistics. There was no onset risk of LEAD according to the gene logistic regression analysis. Conclusion:The SNPs of rs10124755, rs2980083, rs1800976, rs4149341, rs2066714, rs2066715, rs2066716, rs2230808 and rs2246293 might not correlate with the susceptibility of LEAD in Han population of Minnan.

The authors observed the development of the organ of Corti in the temporal bones of 64 human fetuses of various fetal ages by means of comparing celloid sections with surface preparations. The organ of Corti just begins to appear in the second month. Most rapid development occurs in the period from the third to the fifth month. Afterwards, the principal structure of the organ of Corti tends to be stable with no further major changes, except for the differentiation and maturation of the intracellular components. In the fifth month, the major part of the higher columnar epithelial cells on the inner Side of the tunnel begins to degenerate and disintegrate before the formation of the inner spiral sulcus. But a few epithelial cells turn into large wandering cells. The authors discussed the characteristics, function and possible transformation of the wandering cells and compared them with essentially similar cells that appear in the developing central nervous system.

Objective To study the short and long-term effects of vocational rehabilitation on the disabled with low job satisfaction.Methods 66 disabled workers were divided into control group (n=32) and treatment group (n=34). The treatment group accepted physical,occupational and psychosocial therapy for 4 weeks. All the workers were assessed with Minnesota satisfaction questionnaire before treatment,3 and 12 months later. Results The total, internal and external satisfaction significantly improved in treatment group after treatment (P<0.01), except the internal satisfaction 1 year later (P>0.05). Conclusion Specific vocational rehabilitation programme may promote the inclusion of disabled workers into the workplace.

AIM The purpose is to study the influences on serum insulin and glucose by different fasting time in alloxan (ALX)-induced diabetic mice. METHODS Normal mice of serum glucose were determined at different fasting time. According to different fasting time (0 h, 6 h, 12 h, 18 h and 24 h), mice were divided into 5 diabetic experimental model (DEM) groups induced by ip ALX 200 mg/kg and 1 control group. Serum glucose (SG) and body weight were determined at experimental d0, d3, d8 and d13 and serum insulin concentration (SIC) at experimental d13. The death rate and succeeding rate were also observed during experimental time. RESULTS Along with prolonged fasting time, SG、death rate and succeeding rate were increased in DEM mice, SG of normal mice, and SIC and body weight of DEM mice were decreased. Results showed that the optimal fasting time of ALX-induced diabetic mice was 12~18 h a lower death rate and impairment to pancreatic islets. Fasting 18h diabetic mice had higher succeeding since during this time rate、lower death rate and longer hyperglycemia time. CONCLUSION This study indicated SG of mice in vivo had a protective effect against impairment action of pancreatic islets by ALX.

Objective To compare the recent adverse reactions caused by 131I-Metuximab (licartin) treatment via two different routes and to assess the safety and advantages of peripheral intravenous bolus of licartin for the treatment of advanced HCC.Methods Clinical data of 54 patients (45 males,9 females,age 33-80 years) with advanced HCC treated with Licartin in Tianjin Medical University Cancer Institute and Hospital from October 2010 to March 2013 were collected and analyzed.The patients were divided into vein group (n=33) with Licartin injected through peripheral vein and artery group (n =21) with Licartin injected through hepatic artery.The results of blood routine examination,liver and kidney function and thyroid function between the two groups (1 week before treatment,4 and 12 weeks after treatment) were compared.The adverse reaction rate (ARR) and adverse reaction progression rate (ARPR) were also compared between the 2 groups.Ten days after Licartin treatment,all patients underwent gamma imaging to access the drug distribution in vivo.x2 test and two-sample t test were used to analyze data.Results There were no significant differences on age,gender and TNM staging between the vein group and the artery group (t =0.721,x2=0.561 and 4.769,all P>0.05).The vein group showed temporary drug-related leucopenia (x2=7.041,P<0.05) and increased level of serum total bilirubin (STB;x2 =10.297,P<0.05) 4 weeks post-treatment.Twelve weeks later,the above parameters returned to baseline.In artery group,no influence on liver and kidney functions was observed,but the numbers of WBC and PLT decreased significantly (x2 =8.949 and 8.778,both P<0.05) and returned to baseline 12 weeks post-treatment.The ARR in patients who had normal ALT levels before treatment between the two groups was significantly different(3.33%(1/30) vs 5/19,x2=5.718,P<0.05).No significant difference was observed on ARR in patients with normal level of other parameters,and on ARPR in patients with abnormal preoperative parameters between the two groups (x2 =0.000-2.500,all P>0.05).The drug's in vivo biodistribution and the thyroid function between the 2 groups showed no significant difference.Conclusion The peripheral intravenous bolus administration of Licartin is safe to treat patients with advanced HCC.

Integration and sharing of biological samples are the most effective approach for making use of their stock and improving their utilization efficiency. Although great success has been achieved in development of Biolog-ical Samples Library in China, efforts are not made in promoting sample resource sharing. The problems in develop-ment of Biological Samples Library were thus summarized in this paper by content analysis, such as no unified crite-ria, poor administrative management, and imperfect ethical supervision of sample sharing.
