ABSTRACT
Objective To observe the level changes and clinical diagnostic value of follicular statin -1 (FSTL1)in the serum of patients with different types of acute coronary syndrome(ACS).Methods Collected the clinical diagnosis of acute coronary syndrome patients 98 cases,which contained ST segment elevation my-ocardial infarction(STEMI)in 34 cases,non ST elevation myocardial infarction(NSTEMI)in 28 cases,unsta-ble angina pectoris(UA)in 36 cases,while the examination resuLts of healthy people as a control group of 20 cases.The Venous blood was collected and the FSTL1 levels of the 4 groups were detected by ELISA.Results The levels of Serum FSTL1 in ACS group was significantly higher than that in normal control group(P<0.05).Serum FSTL1 of the ACS group were significant correlated with Gensini score,cTNT,hs-CRP(related coefficient:0.210,0.236,0.219 separately).The AUC of FSTL1 was 0.910(95% CI:0.832 -0.988),which was lower than cTNT.The best cut-off value of FSTL1 as a biomarker was 5.65 μg/L(specificity:84.2% and sensitivity:77.5%).Moreover the combination of FSTL1,HDL and cTNT exhibited significantly higher AUC=0.945(95% CI:0.909 -0.981)than did other biomarkers alone or pair combinations.Conclusion In pa-tients with acute coronary syndrome,serum FSTL1 levels has a positive correlation with the degree of coro-nary stenosis and inflammation reaction,and has certain value in the diagnosis of acute coronary syndrome.
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 evaluate the diagnostic performances of seven estimation formulas for glomerular filtration rate (GFR) in pre-operative patients with renal cell carcinoma.Methods A total of 386 pre-operative patients with renal cell carcinoma in the first affiliated hospital of Chongqing medical university from January 2012 to October 2014 were selected.All the patients' GFRs were measured by the renal dynamic imagingwith 99mTc-DTPA as reference (rGFR) and the seven GFR estimation equations (eGFR) were compared with the rGFR respectively.Their correlations and consistencies were observed with spearman correlation analysis and Bland and Altman analysis.The diagnostic sensitivity,specificity and likelihood ratios were calculated and the eGFR accuracies were assessed with receiver operator curve (ROC) analysis.Results The correlations between the rGFR and eGFRs were significantly (P＜0.001).In addition,CKD-EPI-Asian Crea and Ruijin formula were more accurate than others in different stages with larger ROC area in diagnosing renal cell carcinoma.Conclusion There were significant correlations between the eGFRs and rGFR,but some deviations existed.CKD-EPI-Asian Crea and Ruijin formula were more suitable for assessment of eGFR of pre-operative patients with renal cell carcinoma.However,both of these equations had a few limitations.
ABSTRACT
Objective To explore how to optimize laboratory work flow in regional laboratory information management system (LIS) .Methods Upgraded both software and hardware ,reduced manual operation ,and to avoid the mistake and improve the effi‐ciency .Results Compared to the original process ,the optimized one reduces the time line by 57% .Furthermore ,time cost of other individual processes ,such as patient information input ,sample collection and sample classification were also shortened significantly . Conclusion By work flow rebuilding ,we not only improved the efficiency of laboratory work by saving time cost ,but also reduced the error rate ,which finally satisfied our patients .
ABSTRACT
OBJECTIVE@#To summarize endoscopic management of cerebrospinal rhinorrhea and position-determining means.@*METHOD@#Fifteen cases of cerebrospinal rhinorrhea treated by endoscopic approach at our institution were analyzed retrospectively. Aetiology included accidental trauma (10), surgical trauma (4), idiopathic (1). All patients presented with CSF rhinorrhea. Six cases were operated after failure of conservative treatment. Two cases after failure of neurosurgical repair were referred to our department. The largest defect was as big as 2.5 cm x 1.5 cm. All patients were scanned by computed tomography and magnetic resonance imaging and confirmed by biochemistry test. Ten patients received high resolution spiral computed tomography bonding ventriculography.@*RESULT@#We performed intranasal endoscopic repair in all 15 patients. All repairs were successful at the first attempt with a mean follow up of 20 months. One patient had light headache postoperatively and relieved with conservative treatment. All defects of skull base detected by computed tomography and ventriculography were confirmed in the operation.@*CONCLUSION@#Intranasal endoscopic repair of cerebrospinal rhinorrhea can be an effective method. High resolution spiral computed tomography scan combined with ventriculography is a precise position-determining means. With the advancement of instrument and operative skill, the scope of endoscopic repair will further extend.

ABSTRACT
Objective:To investigate the effect of the blood sampling on the result of laboratory examination in the course of transfusion and to search for an appropriate time gap to obtain the unaffected examination result after transfusion.Methods:The subjects were divided into 4 groups,with 10 persons in each group.Blood samples were taken from all the subjects on empty stomach before transfusion,and then 500ml of 0.9%NaCl were administered intravenously on the forearm of the subjects.The 1st group,after 1h of transfusion,underwent the same side blood sampling in vein.The 2nd group,after 1h of transfusion,underwent,the other side blood sampling in vein.The 3rd group underwent the other side blood sampling in vein after transfusion.The 4th group underwent the other side blood sampling in vein,1h later after the finish of transfusion.RBC,WBC,HGB,PLT,K~+,Na~+,Cl,Ca~(2+),GLU,BUN,Cr,TP,ALB,AST,ALT,TBIL,GGT,ALP were tested.Results:The same side blood sampling during transfusion showed the greatest effect on the result of examination,with remarkable difference(P
