Objective To study the effect of early application of heparinate in fulminant epidemic cerebrospinal meningitis in children.Methods Twenty eight patients of fulminant epidemic cerebrospinal meningitis were reviewed and summarized.Results After application heparinate, there were 14 out of 28 platelet increase,12 patients died of diffuse intravascular coagulation.Conclusion Early application heparination is safe and effective in fulminant epidemic cerebrospinal meningitis,and side effect such as hemorrhage is not found.

In order to decrease the mortality of pre-hospital sudden death events(SDEs),their features especially those of cardiac sudden death were analyzed. 1030 pre-hospital emergent cases from 1973～1999 were analysed systematically. The total SDEs occurred in 106 cases, among the 68 cases of cardiovascular diseases, 89.7% had coronary heart diseases(CHD), AMI or OMI with re-infarction. There were two peak age stages of SDEs: the first was 46-55 years old stage(non-retaired age stage,22.6%), and the second stage was 66-75 years old(27.3%). The pre-hospital SDEs are the most emergent cases. Great attention must be paid to those with the history of cardiovascular diseases, especially those with the history of coronary cardiac events

Objective:To explore psychological characteristics and influential factors of impulsivity of 8～12 years-old children with attention deficit hyperactivity disorder.Methods:70 children with ADHD and 126 controls and their parents were evaluated with BIS,SCARED,DSRSC,CSD,TMD and WCST.Results:①Children with ADHD showed significantly more impulsivity,higher anxious mood and depressive mood,lower social desirability,and time management disposition(P

A cross sectional study of 769 patients was performed to evaluate the association of blood uric acid with coronary heart disease (CHD) in different metabolic disorders. It showed that uric acid was not independently associated with CHD. However, when the other abnormal metabolic factors were absent, uric acid might be related to CHD.

Objective To explore the differences in mental health self-help status of empty-nesters between urban and rural areas for providing the basis and strategies in mental health self-help and promoting development of the self-help potential.Methods Inner Mongolia Chifeng district,441 cases of urban and rural empty-nesters was valuated with the mental health questionnaire.Results Urban empty-nesters were higher than the ratio of rural empty-nester on the aspects of residential satisfaction,participating in activities,talking about their problems in families,communicating health informations and seeking professional help,x2=8.193,15.930,6.500,13.089,18.857,P ＜ 0.05.Urban empty-nesters were lower than the ratio of rural empty-nester on the aspects of feeling helpless and hiding bad mood,x2=9.930,14.873,P ＜ 0.05.The awareness on mental health knowledge was in low level for both urban and rural areas(17.11％,32/187 and 9.55％,19/199).Conclusions Both urban and rural empty-nesters were in bad conditions of mental health self-help ability,especially for rural empty-nesters.The awareness rate of knowledge on mental health is in highly need.

Objective:To investigate the inhibitory effect of RNA interference (RNAi) on the expression of Aurora-A in SKOV3 cells and on proliferation of SKOV3 cells.Methods:Two pairs of oligo small interference RNA (Oligo siRNA) specific for Aurora-A were designed for RNAi and were transferred into SKOV3 cells.The expression of Aurora-A were de- tected by RT-PCR and Western blot.Furthermore,the cell proliferation and apoptosis were observed by MTT and FCM af- ter transfection.Results:After transfection with Oligo siRNA,mRNA and protein level of Aurora-A gene in SKOV3 cells were obviously reduced,while the inhibitory rate of proliferation and apoptosis rate in SKOV3 cells were increased signifi- cantly.Conclusion:The Oligo siRNA specific for Aurora-A can reduce the expression of Aurora-A gene and induce apop- tosis of SKOV3 cells.

To optimize Chinese hamster ovary (CHO)expression system and establish a process of screening CHO cell lines with high productivity;neomycin-phosphotransferase (NPT)expressed by the resistance marker gene on the expression vector was mutated with amino acid D at 261 changed to G.After selection by culturing with G418;the survival rate of CHO cells bearing mutant-NPT was significantly lower than that of the cells bear-ing wide type NPT.An enhanced green fluorescent protein (EGFP)was genetically linked to the N terminus of the IgG1 Fc fragment part to generate an EGFP-Fc fusion protein regarded as a report gene;which verified that the resistance of mutant-NPT to G418 was weakened.By comparing fluorescence assay of EGFP intensity in stable transfections after selection with the same concentration of G418 for 3 weeks;mutant-selected pools expressed more exogenous protein than the WT-selected pools.Therefore;the ratio of high producers in a transfected cell population greatly increased.

Objective To investigate the relationship between depression and personality and social support of the urban and rural empty-nest, clear the influence factors of depression in the empty-nest elderly. Methods 398 cases of urban and rural empty-nesters selected from the Chifeng district, were valuated with the general information questionnaire, the Geriatric Depression Scale (GDS), Eysenck personality Questionnaire- Revised Short Scalr for Chinese (EPQ-RSC) and the Social Support Scale (SSRS), and to investigate the demographic data, depression, personality and social support. Results Rural cases had a higher level (14.41±3.09) points of depression than (12.90±2.64) points of urban cases, and the difference was statistically significant (t=5.254, P<0.01);rural empty nesters′subjective support (18.35 ± 2.14) points, objective support (6.37 ± 1.40) points, support utilization degree (6.01 ± 1.17) points and social support score (30.37 ± 4.24) points, were lower than (19.83 ± 2.27) points, (7.34 ± 1.13) points, (6.95 ± 1.12) points, (34.12 ± 3.73) points of urban′s, and the difference was statistically significant (t=6.673-8.490, P<0.01); the extraversion score of urban empty nesters was (7.58 ± 2.51) points which was higher than (6.37 ± 2.02) points of rural empty nesters, and the difference was statistically significant (t=5.273, P<0.01);the neuroticism score (10.38 ± 2.06) points and psychoticism score (9.42 ± 2.17) points of urban empty-nest were lower than (12.41 ± 2.25) points, (10.94 ± 2.10) points of empty-nest′s, and the difference was statistically significant (t=9.401, 7.107, P<0.01). Neuroticism and psychoticism was shown to be positively associated with depression while extraversion and social support to be negatively associated with depression (P<0.01). Regression analysis showed that marital status, income, children visit frequency and the education level were the main influencing factors of depression in the urban and rural empty-nesters. Conclusions There are differences between rural and urban empty-nest elderly in the aspect of general data, depression status, personality and social support, and should intervention them effectively according to their different characteristics.

Objective To analyze the clinicopathological features of bilateral primary breast cancer (BPBC) by molecular subtypes.Methods Clinical data of 145 BPBC patients were reviewed focusing on the clinicopathological features of different molecular subtype and the concordance of molecular subtype between first and second primary breast cancers.Results Of the first primary breast cancers ( FPBC),91 cases (62.8％ ) were Luminal A subtype,Luminal B subtype in 13 cases (9.0％ ),Human epidermal growth factor receptor 2 (HER-2) subtype in 14 cases (9.7％ ),triple negative breast cancer (TNBC) in 27 cases ( 18.6％ ).Of the second primary breast cancers ( SPBC ),Luminal A subtype was found in 93 (64.1％ ) cases,Luminal B subtype in 10(6.9％ ) cases,HER-2 subtype in 14(9.7％ ) cases and TNBC in 28( 19.3％ ) cases.Most TNBC patients were young ( age ≤ 50 ) with high frequency of grade Ⅲ in FPBC.Molecular subtypes do not vary with tumor size,clinical stage,lymph node status and pathological types ( P ＞ 0.05 ).Most FPBC of Luminal A and TNBC were concordant same subtypes in SPBC ( K ＞ 0.04 ),while Luminal B and HER-2 subtypes often had discordant phenotypes in SPBC ( K ＜ 0.04).BPBC were more likely to have concordant subtypes if the two tumors developed in short time interval.Conclusions The distribution and clinical leatures of each subtype in BPBC is similar to unilateral breast cancer.Patients whose FPBC are Luminal A or TNBC often have concordant phenotypes for their SPBC,a short time interval between two cancers also predicts concordance.
