Objective To evaluate the diagnostic accuracy of imprint cytology for intracranial tumors during operation. Methods 150 cases of intracranial tumors were diagnosed by imprint cytology. The imprint was prepared by touching the specimens several times with clean slide, and then the slides were fixed and stained with HE. The diagnostic results obtained by imprint cytology were compared with those made by frozen and routine paraffin sections. Results The accurant rates of diagnosing for non-glial tumors, classifying for incracranial tumors and grading for glial tumors were 100%, 91.3% and 88.3%, respectively. In addition, the morphological features of glial tumors, meningioma, pituitary adenoma on imprint cytology were briefly described. Conclusion The accurant rate of imprint cytology is almost equal to that of frozen section, and both the detection methods have a supplementary effect to each other.

Objective In order to understand the mechanism of solute transperitoneal transport, we studied the relationship between IL-8 level and protein transperitoneal transport. Method 12 New Zealand White rabbits were randomly divided into experimental and control groups. 2 5% glucose peritoneal dialysis solution (40ml/kg)contained 3?10 9 CFU staphylococcus aureus 1ml was injected into the abdominal cavity of experimental NZW rabbits and 2 5% glucose peritoneal dialysis solution (40ml/kg)contained 0.9%NaCl solution 1ml was injected into the abdominal cavity of controlling NZW rabbits. The plasma and effluent concentrations of blood creatinine ,glucose,total proteins and albumine were determined respectively, the D/P or D/Do values of creatinine , total proteins ,albumine or glucose were calculated respectively. Results The D/P ratios of creatinine, total proteins and albumin were increased significantly, while the D/Do of glucose was decreased in experimental group on different dwelling time points ,there was a significantly difference,as compared with the control group (P0 05),while there was significantly correlation after 60 mins(P

Objective To explore the signification and method of Cut-off verification and gray zone setting in chemiluminescent assay.Methods NCCLS EP-12 A2 document defines that C50 is the analyte concentration of cut off value for immunology qualitative test and C5-C95 interval is the range of analyte concentration that yields 5％ positive results to 95％ positive results for immunology qualitativc test.The C50 and C5-C95 interval of HBeAg in ARCHITECT i2000 were worked out according to the cut off value provided by HBeAg reagent calibrated in ARCHITECT i2000,which were verified to approve the character declaimed by manufactory or not.Gray zone was set and the procedure of cut off verification and gray zone set in chemiluminescent were built; A set of quality control was detected 20 times with two different lot HBeAg reagent kits,S/CO was caculated and compared with t test.Results C50 and C5-C95 interval of reagent (lot 06087L100,96378HN00) were 0.171 PEI U/ml,0.125 PEI U/ml; ＞0.154 PEI U/ml to 0.188 PEI U/ml,0.119 PEI U/ml to ＜0.150 PEI U/ml,respectively.S/CO of negative quality control and positive quality control were (0.550 ±0.038),(2.422 ±0.084) and(0.334 ±0.063),(3.587 ±0.321),respectively.They all approved the character (the sensitivity at cut off was less than 0.5 PEI U/ml)declaimed by manufactory,and the results of S/CO between two lot kits were obvious difference (t =9.944,15.499,P ＜0.01).Conclusion C50 and C5-95 interval can be used to verify cut off value and set gray zone in chemiluminescent assay;They may vary in different lot reagents and they must be verified to approve the character declaimed by manufactory.

Urinary tract infection (UTI)is a commonly encountered disease during routine clinical care. In the mean time, it is also a commonly encountered hospital acquired infection. UTI possesses various clinical symptoms, and usually the symptoms are atypical. The detection of leukocyturia and bacteriuria is an essential index for screening and confirmatory diagnosis of UTI. This article summarized the pathogenesis of UTI, diagnostic criteria, clinical significance and application evaluation of detection of the WBC and bacteria in urine.

Hypoglycemia is a common metabolic problem in newborn infants,which might lead to brain injury even brain death when it keeps extremely low for a long time.Therefore,it is of great importance to monitor blood glucose in neonates,especially in groups of infants who are at risk of hypoglycemia,in order to identify and treat this condition and prevent adverse neurological outcomes promptly.It is given that infant of a diabetic mother,preterm neonate,low birth weight and asphyxia are its risk factors.Relative to blood glucose monitoring methods in clinical,continuous glucose monitoring system is comprehensive,continuous and with low pain.Continuous glucose monitoring system has been applied in high-risk neonates of hypoglycemia in recent years.It is of great help to understand the complete picture and change trend of blood glucose,optimize blood glucose management,study newborn glucose metabolic characteristics and the relationship between hypoglycemia and brain damage,so as to define and manage neonatal hypoglycemia.

Objective:To explore the prevalence of posttraumatic stress symptoms among preschool children and its related factors after the Ludian earthquake.Methods:A total of 62 children's guardians were visited.They were interviewed with the Posttraumatic Stress Disorder Semi-Structured Interview for Infants and the Young Children and the Child Behavior Checklist-Posttraumatic Stress Disorder scale (CBCL-PTSD) consisted of 15 items from the CBCL.All of the participantsresided in Longtoushan settlement and Longtoushan town (the epicenter).They were randomly visited from west to east in that region.Results:The rate of scored 9 (or more) on the CBCL-PTSD among children was 51.9％ (27/52) in 1-2 months after the earthquake.However,based on the Semi-Structured Interview,the rate of the children's posttraumatic stress symptoms was 26.9 ％ (14/52).The numbers of posttraumatic stress symptoms,intrusion symptoms,avoidance symptoms,hyperarousal symptoms,the new symptoms and the CBCL-PTSD scores were positively correlated (0.30-0.73,P ＜0.05),except the relation between intrusion symptoms and hyperarousal symptoms.The rate of intrusion symptoms was significant higher among those who experienced earthquake than those who didn't (96.2％ vs.60.0％,P ＜0.01).And the rate of intrusion symptoms was also higher among those who was injured during the earthquake than those who wasn't (100％ vs.84.6％,P ＜ 0.05).And the other symptoms were not difference in children under different conditions (P ＞ 0.005).Conclusion:The preschool children who experienced earthquake or were injured suffer more posttraumatic stress symptoms.

This paper introduces the concept,the research paradigms and the related theory of the attentional blink,and reviews the relevant researches about the attentional blink of the children and adults with ADHD in the last 10 years.Compared to normal subjects,children and adults with ADHD did show more severe AB effect,and adults with ADHD showed more eye movement behavior.In future studies,standardized RSVP paradigm should be set up to provide convenience for the comparison of results of studies,and find out what kind of processing restrictions will affect the characteristics of different age ADHD groups in the time dimension of attention.In addition,ADHD and inhibitory control related closely,consideration should be given to the combination of inhibitory control paradigm and AB paradigm.

Objective To observe the therapeutic effect of Sanzi Yangqing Decoction (Decoction of three kinds of seeds) for mammary cystic hyperplasia.Methods Totally 113 patients with mammary cystic hyperplastia were randomized into a treatment group (58 cases) which was prescribed Sanzi Yangqing Decoction and a control group (55 cases) which was given Ruhe Sanjie Tablet (Tablet for dissolving mammary masses). Both were treated for 3 courses. Before and after treatment the clinical symptoms and signs, hormones in serum of both groups, and the indices of hemodynamics of the treatment group were observed.Results The total effective rate of the treatment group was 89.66%, while that of the control group was 65.45%, there was significant difference (P
