1.Genetic research progress of bicuspid aortic valve and it's clinical significance
International Journal of Pediatrics 2010;37(2):149-151,154
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 explore the relationship between the endogenous plasma cortisol and the airway remodeling associated cytokines which was infected respiratory syncytial virus (RSV) through measuring the levels of them.Methods Forty-two infants diagnosed as acute RSV infection were divided into two groups,severe group(21 cases) and mild group(21 cases),as well as 21 healthy infants for control group.The levels of matrix metalloproteinase-9 (MMP-9),tissue inhibitor of metalloproteinase-1 (TIMP-1) and transforming growth factor- β1 (TGF- β 1) were determined by ELISA,the levels of plasma cortisol were determined by radio immunoaasay.Results The levels of plasma cortisol in severe group [(236.25 ± 119.87)μg/L] were significantly higher than those in mild group [(130.62 ±73.04)μg/L] and control group [(56.35 ±34.52)μg/L],there were significant differences (P <0.05),and the mild group was significandy higher than the control group(P< 0.05).The levels of TIMP-1 and TGF- β 1 in severe group were significantly higher than those in mild group(P< 0.05),and the mild group was significantly higher than the control group (P < 0.05 ); the ratio of MMP-9 and TIMP-1 in severe group was significantly lower than that in control group (P <0.05);the levels of MMP-9 in severe group were significantly higher than those in mild group (P <0.05).The levels of lymphocytes,eosinophilic cells and CD4+,CD8+ in severe group were significantly lower than those in mild group (P<0.05),and significantly lowerthan those in control group (P < 0.05 ).The levels of eosinophilic cells and CD8+ in mild group were significantly lower than those in control group(P < 0.05 ).Conclusion The infection of RSV results in the imbalance of the airway remodeling associated cytokines,which is a danger factor,and the imbalance may be related to the increased level of the plasma cortisol.

[Objective]To investigate the clinical value of computed radiography(CR),computed tomography(CT)and magnetic resonance imaging(MRI)in spinal tuberculosis.[Method]Forty-one patients with histologically confirmed spinal tuberculosis underwant imaging examinations.Forty-one patients were performed CR,22 CT and 31 MRI.[Result]CR of 38 patients clearly revealed bone changes and narrowed or disappeared disk space.CR of 30 patients well showed the abnormal soft tissue.CT scan of 22 patients clearly depicted calcification and no abnormal was found in pedicles in all the 22 CT scans.CT scan of 21 patients revealed bone changes of vertebral bodies and CT scan of 20 patients showed abnormal soft tissue.The soft tissue was involved in all 31 patients with spinal tuberculosis.Diskspaces were involved in 29 cases and the pedicles were normal in all 31 case.The lesions showed hypointense in T1 scan primarily,hyperintense in T2 scan primarily.[Conclusion]CR is the first imaging approach for spinal tuberculosis.CT well reveal the extent and minute calcification.The extent,abnormal soft-tissue and abnormal disk space are more dramatically demonstrated on MRI imaging.CR,in addition to CT and MRI,is helpful in diagnosis of spinaltubereuinsis.

Ossification of the posterior longitudinal ligament (OPLL) is common clinical spinal disorders often occurring in the cervical spine,with the main symptom being nerve compression.The specific mechanism of OPLL remains unclear,but genetic factors,single nucleotide polymorphisms (SNPs),mechanical stimulation,metabolism abnormality might be involved in the etiology of the disease.Multiple genetic and environmental factors may contribute to the development of OPLL.OPLL has prominent genetic characteristic,and it is associated with SNPs of several genes.Here we review the SNPs of several genes (COL11A2,BMP-2,TGF-?1,TGF-?3,NPPS,COL6A1 and Runx2) which contribute to the development of OPLL,hoping to lay a foundation for future study.

Objective To explore the clinical application of reconstructing silicone elastomer nose prosthesis by means of selected laser sintering and wax powder PCPI. Methods Laser scanning was used to get the 3-D data of a nose model. Surfacere 10.0 etc softwares was used to reconstruct the nose by mirroring the digitalized model of absent nose. Selective laser sintering and wax powder was chosen to fabricate a wax nose model and the nose prosthesis made by silicone clastomer. Results Perfect silicone clastomer nose prosthesis was made for 2 patients. Conclusion This study suggests that the wax nose model and the new wax powder can meet the requirement of clinical expectation for maxillofacial prosthesis.
9.A clinical study of total intravenous anaesthesia in laparoscopic operation
Chinese Journal of Postgraduates of Medicine 2008;31(z1):38-41
Objective To evaluate the recovery and hemedynamics of total intravenous anaesthesia (TIVA) with propofol and remifentanil. Methods Thirty ASA Ⅰ - Ⅱ patients undergoing hperoscopic oper-ation were randomly divided into the TIVA group(group A,n=15) and the combined intravenous with inhala-tion anaesthesia greup(group B,n=15). Anaesthesia was induced in the same manner in both greups:Midazo-lam 0.05mg/kg,vecurium 0.1mg/kg,propofol 1.5mg/kg and remifentanil 1.5 μg/kg.Remifentanil was infused 2.5 μg/ml) in group A or with sevoflurane( 1.3% end-tidal) in group B to maintain anaesthesia. With termi-nation of surgery,anaesthetic delivery was discontinued simuhaneously.Bp,HR at all stages and recovery profiles were recorded. Results (1)Between before inflation and after inflation or between at the end of op-eration and the basic values in group A,there were no significant differences in Bp,HR. (2) Times from stop-ping administration of anaesthetics until full spontaneous respiration and eye opening were similar for two groups.Time for trachcal extubation was significantly less in the group A than group B. (3)The rates of post-operative nausea or vomiting were similar. Conclusion The application of TIVA with propefol and remifen-tanil is associated with better hemodynamic stability and better recovery profile as compared to the combined intravenous with inhalation anaesthesia.
