ABSTRACT
Objective To analyze the relationship between biochemical level and severity levels and clinical,duration of disease in patients with Parkinson Disease (PD).Methods 69 patients with PD and 69 healthy persons of similar sex and age were selected in the research.Serum uric acid and lipids levels were examined and compared.Results The serum uric acid,triglycerides,total cholesterol and low-density lipoprotein cholesterol (LDL-C) were (322.48 ± 66.18) μmol/L,(1.22 ± 0.86) mmol/L,(4.70 ± 0.92) mmol/L and (3.00 ± 0.85) mmol/L in control group,and (384.23 ± 88.28) μmol/L、(1.64 ± 0.94) mmol/L、(5.37 ± 1.31) mmol/L、(3.53 ± 1.03) mmol/L in control group.The differences are significant (t =-4.68,P =0.000;t =-2.74,P =0.007;t =-2.74,P =0.007;t =-3.49,P =0.001;t =-3.27,P =0.001).Serum UA concentration and high-density lipoprotein cholesterol (HDL-C),LDL-C were lower in patients with Parkinson's disease in duration of disease more than 3 years than those in duration of disease less than 3 years (t =3.373,P =0.001;t =2.440,P =0.017).The serum UA levels of any stages of PD patients were lower than the control group (P ＜ 0.05) according to Hoehn-Yahr staging.All lipid levels in early and middle stage PD disease patients were lower than those in control group (P ＜ 0.05).Serum UA,total cholesterol and HDL-C in female PD patients were (305.69 ± 54.25) μmol/L,(4.99 ± 0.95) mmol/L,(1.25 ± 0.27) mmol/L,and (339.76 ± 73.40) μmol/L,(4.41 ± 0.81) mmol/L,(1.06 ± 0.19) mmol/L in male patients.The difference is significant (t =2.198,P =0.031;t =-2.721,P =0.008;t =-3.266,P =0.002).Multivariate logistic regression models assessed lower uric acid concentrations is the risk of PD (OR =1.01,95％ CI 1.004 ～ 1.015,P =0.001).Conclusion Biochemical level changed differently in Parkinson disease and uric acid reduction could be a risk factor for PD.
ABSTRACT
AIM: To investigate the expression of TNF-?, TGF-? in patients with oral lichen planus (OLP) and normal oral mucosa (NOM). METHODS: An immunohistochemical technique was performed to detect TNF-?, TGF-?_1 and TGF-?_2 expression in 22 cases with OLP and 10 normal controls. RESULTS: In lamina propria of OLP, the expression of TNF-? and TGF-?_1 were increased, whereas TGF-?_2 did changed significantly compared with control group. TNF-? positive signal were mostly found in macrophages, lymphocytes. TGF-?_1 positive cell was present in macrophages, endothelial cells and fibrocytes. CONCLUSION: TNF-? and TGF-?_1 play an important role in the development and maintenance of OLP local inflammation.
