A lot of important information were hidden in mass LIS data.Data mining technology can find useful data from multiple dimensions,providing information support for clinical diagnosis and treatment.This paper described the newly gained features of the laboratory medicine in the era of big data and analyzed the potential application of data mining in laboratory medicine.

Objective To explore clinical value of detection of carcinoembryonic antigen(CEA) ,cytokeratin 19 fragment(CY-FRA21-1) and neuron specific enolization enzyme(NSE) in pleural effusion and serum during the differential diagnosis and patho-logical classification of lung cancer .Methods 180 patients with pleural effusion were divided into two groups ,one including 55 be-nign pleural effusion cases(benign pleural effusion group) and the other including 125 lung cancer cases(lung cancer group) .CEA , NSE and CYFRA21-1 in pleural effusion and serum of two groups were measured ,respectively ,and the measure results between two groups were conducted .Results CEA ,NSE and CYFRA21-1 levels in lung cancer group were significantly higher than those in benign pleural effusion group(P<0 .05) .CEA levels in pleural effusion and serum in lung adenocarcinoma group were significantly higher than those in benign pleural effusion group ,lung squamous carcinoma group and small cell lung cancer group(P<0 .05) .CY-FRA21-1 levels in pleural effusion and serum in lung squamous carcinoma group were significantly higher than those in benign pleu-ral effusion group ,lung adenocarcinoma group and small cell lung cancer group(P<0 .01) .NSE levels in pleural effusion and serum in small cell lung cancer group were significantly higher than those in benign pleural effusion group ,lung adenocarcinoma group and lung squamous carcinoma group(P< 0 .01) .The positive detection rate of CEA in lung adenocarcinoma group was significantly higher than that in lung squamous carcinoma group and small cell lung cancer group(P<0 .05) .The positive detection rate of CY-FRA21-1 in lung squamous carcinoma group was significantly higher than that in lung adenocarcinoma group and small cell lung cancer group(P<0 .05) .The positive detection rate of NSE in small cell lung cancer group was significantly higher than that in lung squamous carcinoma group and lung adenocarcinoma group(P<0 .01) .Conclusion CEA ,CYFRA21-1 and NSE in pleural effusion and serum are specific tumor markers of lung adenocarcinoma ,lung squamous carcinoma and small cell lung cancer ,respectively , which may have a certain clinical significance for the differential diagnosis and pathological classification of lung cancer .

ObjectiveTo investigate the effects of atorvastatin on cardiomyocyte apoptosis and caspase-3 expression in acute myocardial infarction in rats.MethodsFifty SD rats were randomly divided into 3 group:sham group,control group( normal saline),atorvastatin pretreatment group ( 10mg/kg),The atorvastatin group were pretreated with atorvastatin ( 10mg/kg ) for 3 days,and those in the control group were pretreated with normal saline instead.All rats underwent coronary ligation of left anterior descending branch to establish AMI rat s model on the fourth day except the sham group,while sham group only received thoracotomy without coronary ligation.Then,The infarct size area at risk were defined by Evans blue and TTC staining,the caspase-3 mRNA expression of myocardium was measured with reverse-transcriptase polymerase chain reaction(RT-PCR) and the apoptosis index was analyzed by TUNEL staining.Results Compared with control group,the infarct size,the caspase-3 mRNA expression of myocardium,the apoptotic index were decreased significant in the atorvastatin group ( P ＜ 0.05 ).ConclusionPretreatment with atorvastatin has protective effect on the acute ischemic cardiomyocytes,which may probably be associated with the reduction of the expression of caspase-3 mRNA in the myocardium and the apoptotic index.

Objective To identify the incidence and risk factors associated with urinary tract infection in spinal cord injured patients who accepted sterile intermittent catheterization. Methods 243 patients with spinal cord injury were analysed retrospectively. Results The overall incidence of urinary tract infection was 0.93 episodes per 100 person-days. The risk factors associated with urinary tract infection were age older than 40, frequent exposure to antibiotics, cervical injury, score of functional independence measure less than 71 and bladder dysfunction. The independence risk factors were cervical injury, score of functional independence measure less than 71 and bladder dysfunction. Conclusion High level spinal cord injured patients with lower function and bladder dysfunction are higher risk for urinary tract infection.

Objective To explore the possible relationship between the expression of CD14 and HLA-DR on peripheral blood monocytes and progress of the illness in neonatal infection. Methods To measure the expression of CD14 and HLA-DR on peripheral blood monocytes in the 1st, 5th and 7th days after the neonates were diagnosed as infectious diseases by flow cytometry of dual stai-ning techniques. Thirtyfour uninfected neonates were served as controls. Outcomes were analyzed. Results Neonates with infectious diseases had signi-ficantly lower serum CD14(P

Objective To investigate the mechanism of platelet inhibitor from Agkistrodon halys venom (AHV-PI) on platelet aggregation. Methods Protein kinase Akt phosphorylation levels in platelet were measured by Western blot. XS-1000I blood cell counter was used for platelet count. The plasma content of 5'-NT and platelet membrane GPIb were determined by Enzyme-Linked Immunosorbnent Assay (ELISA). The effect of AHV-PI on binding rate between the fluorescence labeled monoclonal antibody CD61 (FITC-CD61) and platelet membrae glycoprotein Ⅱb/Ⅲa (GPⅡb/Ⅲa) was observed by flow cytometry (FCM). Results AHV-PI can reduce the level of Akt-phosphorylation level and the number of platelet. AHV-PI can increase the content of 5'-NT in plasma, reduce the expression of platelet GPIb. Flow cytometry displayed AHV-PI can not affect the rate of combination between platelet GPⅡb/Ⅲa and FITC-CD61. Conclusion The mechanism of inhibition of platelet aggregation may be inhibit protein kinase Akt phosphorylation to block the signal transduction pathway of Akt. Limit cell grouth and reduce platelet number, also it may be related to its 5'-NT activity, it can degradate ADP to prevent the formation of platelet thrombus.

Objective To investigate CT features and the staging of the ovarian cystadenocarinoma.Methods The CT findings of 73 ovarian cystadenocarcinomas proved by surgery and pathology in 52 cases were analyzed.CT staging in 41 cases with whole abdominal scan was made and the CT finding was compared with operative results.Results Of 73 ovarian cystadenocarcinomas,23(31.5%) tumors were typeⅠ(mainly cystic),32(43.8%)tumors were type Ⅱ(mixed) and 18(24.7%) tumors were type Ⅲ(mainly solid).The preoperative stage accuracy for stage Ⅲ patients was 90.9%.Conclusion CT manifestations of ovarian cystadenocarcinoma are varient,the definite diagnosis can be made by typical appearance.CT scan has a high accuracy in staging of preoperative.
