Bicuspid aortic valve(BAV) is one of the most common congenital cardiovascular malformations,affecting 1% to 2% of the population.BAV may be sporadic or familial.BAV is likely a multiple genetic disorder based on the study of heritability and identification of pathogenic genes and potential candidate genes.With increasing studies of related genes of BAV,early intervention and gene therapy of BAV and associated complications may be likely in the near future.

PAX2 gene encodes a nuclear transcription factor and plays a pivotal role for embryonic kidney development.It is expressed during the entire developmental process of pronephron,mesonephron and metanephron,involving in the regulation of embryonic kidney development at various fetal stages,but its expression disappeared in mature nephrons.Recently,it was found that PAX2 was re-expressed in nephropathy.Gene mutation and re-expression of PAX2 are closely related with congenital and acquired renal diseases.This paper reviews the role and significance of PAX2 expression in kidney disease from the aspects of normal expression,gene mutation and abnormal expression.

Objective To observe the effect of laser irradiation on the level of histamine (Hm) , 5- hydroxytryptamine(5-HT), interleukin-1 (IL-1), tumor necrosis factor α (TNF-α) in serum and β- endorphin (β- EP) in brain tissue in rat model of rheumatoid arthritis. Methods A total of 60 Wistar rats were randomly divided into four groups:a normal group, a model group (RA without treatment), a laser + drug treatment group (RA treated by laser and drug) and a drug treatment group (RA treated by drug alone). All the groups, except the normal one, were injected with complete Freund's adjuvant to make animal model of adjuvant arthritis. All the animals were then treated accordingly. The level of Hm, 5-HT, IL-1 and TNFα in serum and β-EP in brain tissue were measured. Results Laser downregulated the content of Hm, 5-HT, IL-1 and TNFα in serum and increased the content of β-EP in brain tissue. Conclusion Laser irradiation is an effective modality for treating the animal model of rheumatoid arthritis.

Objective To study the clinic characters of patients with latent autoimmune diabetes in adults (LADA). Methods We evaluated the prevalence of acute and chronic complications in the LADA patients with serum antibodies to glutamic acid decarboxylase (GADA) or to islet cell cytoplasmic antigens (ICA). The prevalence of acute and chronic complications were further compared with that in patients with acute onset type 1 or type 2 diabetes. Results The mean age, BMI, fasting and postprandial C peptide levels of the LADA patients were higher than those of type 1 diabetes and lower than those of type 2 diabetes. Of the LADA patients, 29.3% had ketosis. Although the frequency of repeated attack of ketosis in the LADA patients was similar to that in type 1 diabetes, the duration from diabetic onset to first ketosis in the LADA patients was much longer. The prevalence of retinopathy in the LADA patients was 19.5%, which was similar to that in type 1 diabetes. The prevalence of cataract in the LADA patients was 48.8%, which was similar to that in type 2 diabetes. Less LADA patients had microalbuminuria, compared with the other groups. There was no difference in the prevalence of overt nephropathy, neuropathy and hyperlipidemia among the three groups. The prevalence of coronary heart disease in the LADA patients was similar to that in type 2 diabetes. The prevalence of hypertension in the LADA patients was higher than that in type 1 but lower than that in type 2 diabetes. Conclusion The clinic characters as well as acute and chronic complications in LADA patients are different from those in type 1 and type 2 diabetes.

Calmodulin(CaM),as major intracellular Ca 2+ signal transductor,is a ubiquitous, multifunctional protein in eukaryotic cells,invovled in a wide variety of cellular processes . Study of the structure and molecular recognition mechanism of CaM helps better understanding intracellular Ca 2+ signaling system and molecular recognition of protein-protein interaction,giving new insight into medicine development and clinical therapy. This paper reviews progress in the studies of molecular recognition of calmodulin in recent past years.

Objective To evaluate the uniformity of different diagnosis criteria of metabolic syn-drome in patients with type 2 diabetes, especially the criteria that suit for metabolic syndrome in type 2 dia-betes patients.Methods The patients with type 2 diabetes, aged from 20~74 years, who were treated at Department of Endocrinology , the Third Affiliated Hospital , Qiqihar Medical University from January 2008 to November 2009 were enrolled.Four hundred and twenty one patients with integral data were analyzed . Waistline, hip line, height, body mass, blood pressure and so on were surveyed , and according to waistline and hip line the waist-to-hip ratio was calculated .On the basis of body mase/height body mass index ( kg/m2 ) was calculated .The blood sugar was detected with the hexokinase method .The blood cholesterol , tria-cylglycerol , the high density lipoprotein cholesterol were determined with the biochemistry method .Urinates the micro albumin level was determined with chemistry to try the belt technology .Diagnosis standards of WHO (1999), NCEP-ATPⅢ(2001),ACCE(2003),EGIR(1999),the Chinese CDS(2007) suggestion metabolism synthesis drafts , the triacylglycerol-waistline standard of Blackburn P forecast cardiovascular e-vent(2003) were applied to calculate prevalence rate of metabolism synthesis .Results The 421 enrolled testees were involved in the result analysis .⑴Prevalence rates of type 2diabetes and metabolism synthesis in various single component: In the investigation population the differences in body of obesity , hypertension and hypertriacylglycerolemia , the low and high density lipoprotein cholesterol blood sickness between the men and women were insignificant , but the overload (66.1%) in males was remarkably higher than that in females (49.7%).The prevalence rate in abdomen obese in males (74.0%) was remarkably higher than that in females(59.9%).⑵Abnormal distribution of metabolism in patients with type 2 diabetes: Preva-lence rate of one kind of abnormal metabolism was 27.2%.Prevalence rate of two kinds of or above two kinds of above abnormal metabolism was 61.0%.Prevalence rate of three kinds of above abnormal metabo-lism was 26.1%,and the prevalence rate in females was not higher than that of males ( P >0.05 ) .⑶After age and sex lamination ,prevalence rates of metabolism synthesis and it's the correlated disease:The preva-lence rates of the high hypertriacylglycerolemia , hypertension , metabolism synthesis had the tendency of in-creasing along with the age .Prevalence rates of abdominal obesity and the low and high density lipoprotein cholesterol blood sickness had the increased tendency in females , but it was not obvious in males .Except that 35~44 years old of age group prevalence rate of the high hypertriacylglycerolemia in males ( 62.1%) was remarkably higher than that in females ( 29.2%) ( P <0.005 ) , and the 20~35 years old age group prevalence rates of metabolism synthesis in males (41.2%)were remarkably higher than outside the females (20.0%)( P <0.05).In other various age groups ,there was insignificant difference in prevalence rate between males and females .⑷The prevalence rate of WHO diagnosis standard for metabolism synthesis (62.9%) had good concordance with the prevalence rate of the Chinese CDS diagnosis standard for metabo -lism-synthesis ( 66.7%) .The prevalence rate of ACCE diagnosis standard for metabolism synthesis (88.8%) had good concordance with the prevalence rate of the EGIR diagnosis standard for metabolism synthesis (86.6%).The prevalence rate of Blackburn P forecast cardiovascular event (20.9%),which was distanced from the result of the diagnosis standards ( P <0.005 ) .Conclusion ⑴Patients with type 2 di-abetes have high metabolism syndrome proportion rate , and the abnormal metabolism proportion rate in sin-gle group is also higher.⑵WHO (1999) metabolism syndrome diagnosis standard and CDS (2007)sugges-tion standard are suitable for Chinese metabolism -synthesis in type 2 diabetic patients .⑶The metabolism syndrome diagnostic standards of EGIR and ACCE are similar in proportion rate in Chinese patients with type 2 diabetes , which is accorded with the findings of former literatures .Whether that can be used widely deserves further study .⑷The diagnostic criteria of triacylglycerol waistline is not suitable for Chinese type 2diabetic patients.
