ABSTRACT
[Objective] To refer a geographical distribution rule of alpha-L-fucosidase (AFU) reference values for the health adults in China via exploring its spatial distribution trend and its correlation with geographical factors.[Methods] A total of 6564 samples of AFU reference values from 66 administrative units in the years 2004-2015 were collected,male and female of which were 3701 cases (56.4％) and 2863 cases (46.3％).A research concerning AFU reference values in whole country were calculated using methods of information content and ridge regression.[Results] AFU reference values for Chinese healthy adults were influenced by geographical factors and presented autocorrelation,and it showed eastern and northern areas were highery than western and southern areas.[Conclusions] AFU reference values have a spatial variation and the regional disparities should be considered in practice.
ABSTRACT
Objective To evaluate the diagnostic value of combination detection of alpha-fetoprotein (AFP),Golgi protein 73 (GP73) and a-L-fucosidase (AFU) for early hepatocellular carcinoma (HCC).Methods A total of 222 patients with liver diseases in this hospital from March 2016 to March 2017 were collected and divided into the early stage HCC group (74 cases),late stage HCC group (27 cases),liver cirrhosis group (74 cases) and chronic hepatitis B group (47 cases),and contemporaneous 49 individuals undergoing physical examination were selected as the healthy control group.The levels of serum GP73,AFP and AFU were detected in each group.The ROC curve was drawn.The diagnostic values of single detection and combined detection of 3 indicators for diagnosing early HCC were evaluated.Results The serum GP73,AFP and AFU levels in the early stage HCC group were significantly higher than those in the liver cirrhosis group,chronic hepatitis B group and healthy control group (P＜0.05).In the HCC screening,the area under the curve (AUC) of AFP ROC curve for singly diagnosing HCC was 0.910(95％CI:0.864-0.936),AUC of GP73 and AFP combined diagnosis was maximal [0.925 (95％ CI:0.889-0.950)] and the sensitivity was the highest (95.0％).In the differentiation diagnosis between early HCC and liver cirrhosis,AUC of GP73 for single diagnosis was maximal [0.842(95％CI:0.746-0.879)] and the specificity was the highest (86.5％);AUC of GP73 and AFU combined diagnosis was maximal[0.901(95％CI:0.788-0.907)].Conclusion GP73 and AFP for combined detection of HCC can increase the diagnostic efficiency of HCC screening.GP73 and AFU combined diagnosis can increase the diagnosis efficiency of early HCC,which has an important significance for the differentiation diagnosis between early HCC and liver cirrhosis.
ABSTRACT
Objective To observe the detection value of α-L-fucosidase (AFU) in gestational diabetes mellitus (GDM) and the correlation of AFU with total bile acids (TBA).Methods Anthropometric parameters and serum biochemical indexes were recorded and 75 g OGTT was performed then according to OGTT result,patients with GDM were confirmed and matched the control group by age and BMI.Results The level of AFU in GDM group was higher than that that of normal glucose tolerance (NGT) group and associated with 1 hour postprandial glucose.After correcting ALT and HbA1c,AFU correlated with TBA.Conclusions During pregnancy,AFU has reference value for the diagnosis of GDM and 1 hour postprandial glucose is its independent factor.The rise AFU is combined with the decrease of.DBIL but the increase of TBA and ALP,which indicates bile duct system in patients with GDM is in an active state.
ABSTRACT
Objective To investigate the application of alpha-fetoprotein (AFP),α-L-fucosidase(AFU),5'-nucleotidase(5'-NT) and γ-glutamyltransferase (GGT) in diagnosis of hepatocellular carcinoma(HCC),and to provide the basis for its early and rapid diagnosis.Methods The clinical data of 120 cases with initial diagnosis as hepatocellular carcinoma,150 cases with liver cirrhosis,200 cases with hepatitis were analyzed retrospectively from June 2013 to August 2014,meanwhile,100 healthy people were selected as control group.The serum AFP,AFU,5'-NT and GGT levels were measured by electrochemiluminescence immunoassay,rate method,peroxidase method and enzymatic colorimetric assay,respectively.The results were analyzed by receiver operating characteristic (ROC) curve,while the sensitivity,specificity,AUC were calculated at the same time.Results The levels of serum AFP,AFU,5'-NT and GGT were significantly different among HCC group,liver cirrhosis group,hepatitis group and control group (all P＜0.05).When tested alone,the sensitivities of AFP,AFU,5'-NT and GGT were 58.33 ％(70/120),82.50 ％(99/120),85.00 ％(102/120),78.33 ％(94/120),the specificities were 88.33 ％(106/120),73.33 ％(88/120),88.33 ％(106/120),71.67 ％(86/120),and AUC were 0.655,0.702,0.814,0.754.When four indexes were performed with combined test,the sensitivity was 98.33 ％(118/120),specificity was 96.67 ％(116/120),AUC was 0.975,which were higher than the single detection (all P＜0.05).Conclusion The combined detection of serum AFP,AFU,5'-NT and GGT can greatly increase the sensitivity and specificity for diagnosing HCC and will gain mutual complement advantages,which is of great clinical value for early and rapid diagnosis.

ABSTRACT
Objective To evaluate the diagnostic value of serum α-L-fucosidase (AFU)in primary hepatic carcinoma(PHC)by using the meta analysis method.Methods The databases of Cochrane Library,PubMed,web of knowledge(Medline,BIOSIS Pre-views),Springer link and Science Direct were retrieved from January 1997 to December 2013.The domestic databases of CBMdisc (Chinese BioMedical Literature on disc),CNKI,Wangfang and VIP(VIP Database for Chinese Technical Periodicals)were retrieved from January 1984 to December 2013.Retrieval languages were limited to Chinese and English.The related literatures on the study of serum AFU diagnostic value for PHC were collected and the included studies meeting the inclusion criteria were performed the quality assessment.The meta-Disc 1 .4 software was adopted to conduct the analysis for comprehensively evaluating serum AFU value in the diagnosis of PHC.Results 20 articles were included (15 articles in Chinese and 5 articles in English).A total of 2 114 cases in the patients groups and 5 718 cases in the control groups were analyzed.The heterogeneity test was carried out on the in-cluded 20 articles,suggesting that the heterogeneity of the included studies was caused by the non-threshold effect,so the random effects model was selected for conducting the meta-analysis.And the pooled sensitivity was 0.77,the pooled specificity was 0.87, the pooled positive likelihood ratio was 5.37,the pooled negative likelihood ratio was 0.28,the pooled diagnostic odds ratio was 20. 47 and the SROC area under the curve(AUC)was 0.87.Conclusion Serum AFU has highly sensitivity and specificity for the diag-nosis of PHC and has reference value for its clinical diagnosis.

ABSTRACT
Objective To investigate the correlation between hepatitis B virus(HBV)markers and AFU,ALT,GGT.Methods 570 eases of HBV-infected people were divided into 4 groups according to the different performance modes.150 healthy people were considered as control group.rate method was used to detect AFU,ALT and GGT.Estimate the differences between the groups were compared.Results The comparison between the AFU,ALT,GGT in different performance mode of HBV and the control group showed:the differences of group 1,group 2 and group 3 were statistically significant(P＜0.01),the difference of group 4 was not significant(P＞0.01).The correlation between AFU,ALT,GGT of different performance mode showed:the changes of AFU and ALT,GGT in group 1,group 2 and group 3 were positively change-related.But the changes of AFU,ALT and GGT were not clearly related.The distribution of the rise of serum enzyme activity in different performance mode showed:the AFU,ALT and GGT rised in different proportion in group 1,group 2 and group 3.Conclusions The AFU,ALT and GGT activity of HBVinfected persons should be detected at the same time,and evaluate the damage of liver cells.This will do help to predict the progression of hepatitis.
