The user experience (EX) of current Electronic Medical Record systems (EMR) is needed to improve. This paper proposed a new method to enhance EX of EMR. Firstly, system template and text characterization are used to make the EMR data structured. Then, the structured date are mined based on mining the association rules of incremental updating data to find the association of the elements of template of EMR and the values of elements. Finally, with the help of mined results, the users of EMR are able to input data effectively and quickly.

Objective To evaluate the limit of detection of eight enzyme-linked immunosorbent assay (ELISA) according to hospital grade assessment and ISO15189:2012.Methods According to the new health industry standard WS/T 514-2017:"Establishment and verification of detection capability for clinical laboratory measurement procedures",the limit of detection (LoD) was established,in the sameset of detection system,using two reagent lot,each lot for 5 consecutive days 4 consecutive days to assess the value of the concentration of five specimens were detected repeatedly,calculated the corresponding hit rate,then transform into probability units,and the corresponding concentration value production regression model,the hit rate of 95 ％ corresponds to the probability unit 1.645 substituted into the equation,the resulting concentration value was LoD estimates.The detection limit values were tested for 3 consecutive days of detection of two LoD concentrations near the declared concentration of the sample (diluted by the standard material) was detected 4 times repeatedly to calculate the positive result was greater than or equal to the percentage of LoD statement,greater than or equal to the critical value of 87％,then verified success.Results HBsAg:0.100 IU/ml,HBsAb:9.642 mIU/ml,HBeAg:0.666 NCU/ml,HBeAb:3.700 NCU/ml,HBcAb:0.786 IU /ml,HCV:0.506 NCU/ml,TP:2.236 mIU/ml and HIV:0.135 NCU/ml.The detection limit estimates were passed.Conclusion The verification limit of the verification project in the testing method and detection system of the laboratory meet the requirements Objective.

OBJECTIVETo investigate the oxidative damage to lung tissue and peripherial blood in PM2.5-treated rats.

METHODSPM2.5 samples were collected using an auto-sampling instrument in summer and winter. Treated samples were endotracheally instilled into rats. Activity of reduced glutathione peroxidase (GSH-Px) and concentration of malondialdehyde (MDA) were used as oxidative damage biomarkers of lung tissue and peripheral blood detected with the biochemical method. DNA migration length (microm) and rate of tail were used as DNA damage biomarkers of lung tissue and peripheral blood detected with the biochemical method.

RESULTSThe activity of GSH-Px and the concentration of MDA in lung tissue significantly decreased after exposure to PM2.5 for 7-14 days. In peripheral blood, the concentration of MDA decreased, but the activity of GSH-Px increased 7 and 14 days after experiments. The two indicators had a dose-effect relation and similar changing tendency in lung tissue and peripheral blood. The DNA migration length (microm) and rate of tail in lung tissue and peripheral blood significantly increased 7 and 14 days after exposure to PM2.5. The two indicators had a dose-effect relation and similar changing tendency in lung tissue and peripheral blood.

CONCLUSIONPM2.5 has a definite oxidative effect on lung tissue and peripheral blood. The activity of GSH-Px and the concentration of MDA are valuable biomarkers of oxidative lung tissue damage induced by PM2.5. The DNA migration length (microm) and rate of tail are simple and valuable biomarkers of PM2.5-induced DNA damage in lung tissues and peripheral blood. The degree of DNA damage in peripheral blood can predict the degree of DNA damage in lung tissue.

OBJECTIVETo study the diagnosis and management of renal angiomyolipoma (RAML), and to identify risk factors affecting spontaneous angiomyolipoma rupture.

METHODSThe data of 68 patients with RAML from 1989 to 2002 were retrospectively reviewed. These patients were divided in two groups on the basis of tumor size, 35 patients in group A ( 4 cm).

RESULTSSeven patients were identified by image-guided percutaneous biopsy, and no major complications was noted. Sixteen patients with RAML were examined with angiography and 9 of 16 patients had got spontaneous rupture. 41.2% of patients were symptomatic, 4 cases (11.4%) in group A and 24 (72.7%) cases in group B (P < 0.01). There were significant differences in mean tumor size (11.6 cm +/- 5.1 cm vs 5.3 cm +/- 2.9 cm, P < 0.01) and mean aneurysm size (13.6 mm +/- 5.8 mm vs 2.6 mm +/- 3.0 mm, P < 0.01) between 9 cases of the ruptured tumor and 59 cases of unruptured tumor, 9 cases of the ruptured and 7 cases of unruptured tumor with angiography, respectively. Treatment consisted of conservative observation in 10 patients (no radiographic changes during the follow-up of 2 - 7 years); partial nephrectomy in 14 patients, tumor enucleation in 30 patients, total nephrectomy in 14 and posterior laparoscopic nephrectomy in 3 (no recurrence and complication correlation to operation during the follow-up of 2 - 144 months).

CONCLUSIONSIt is an important role that percutaneous biopsy guided by ultrasonography or computerized tomography performs in managing suspicious and/or indeterminate RAML. A higher probability of rupture is related to tumor and/or aneurysms size. Nephron-sparing surgery is the first choice for surgical treatment of RAML.

Objective To study the clinical and laboratory characteristics of adult Japanese encephalitis (JE) patiens in a JE outbreak in Yuncheng, Shanxi province in 2006. Methods All the clinical data from the Second People's Hospital in Yuneheng city were analyzed, part of patients' sera and cerebrospinal fluid were tested by serology and RT-PCR. Results The majority of patients were middle-aged and elderly, 77.8 % (35/45)of the total cases were more than 40 years old. Severe and fulminating type eases accounted for 60.0% (27/45) . Most patients had underlying diseases. IgM antibody to JE virus (JEV) in serum was positive in each of the 45 patients analyzed and 4-fold or greater rise in sera neutralization antibody titer were found in convalescent serum. JEV nucleic acid was positive in part of cerebrospinal fluid specimens. Conclusion Viral encephalitis emerged in Yuncheng city, Shanxi province was Japanese encephalitis B, and most of the eases belonged to elderly group.

Objective To grasp the infection rate and genotypes of Japanese encephalitis virus (JEV) in mosquito in Fujian province.Methods Mosquito specimens in Sanming city,Jianyang city and Fuzhou city in Fujian province were collected in 2010.RT-PCR was used to detect the JEV sequence from the mosquitoes by specific primers.The sequence splicing and the differentiation analysis for nucleotides,deduced amino acid sequence and phylogenetic tree were performed by the software of ATGC,Clustal X ( 1.83 ),MegAlign,GeneDoc 3.2 and Mega (4.0).Results Totally 6987 mosquitoes were collected and main species was Culex tritaeniorhynchus and Anopheles sinensis.The infection rate of JEV in mosquitoes in Sanming,Jianyang and Fuzhou were 1.25％,1.76％ and 0.65％,respectively.One full genome in the positive specimens was sequenced.And further study showed that the positive JEV sequences belonged to genotype Ⅰ.Conclusion Genotype Ⅰ Japanese encephalitis virus is the main genotype in mosquitos in Fujian province.

Objective To explone the rehabilitation nursing intervention of hospital-community integration on the social function of patients with schizophrenia. Methods 240 schizophrenia patients were randomly divided into observation group ( 120 cases) and control group ( 120 cases). Both groups received routine treatment and care. Other than this, observation group received early intervention and rehabilitation care. Social Disability Screening Scale (SDSS) and the Morning Side rehabilitation status scale (MRSS) were used. Recurrence rate and medication compliance of two groups after 1 year were compared. Results Better improvement of the social function and medication compliance, as well as lower recurrence rate was found in the observation group. There was significant difference between the two groups ( P ＜ 0.01 or P ＜ 0.05 ).Conclusions The rehabilitation nursing intervention of hospital-community integration can improve the social function of schizophrenia patients and contributes to their quality of life.
