The etiology of neuroblastoma is related with hereditism,enviroment and matabolic factors.By now,it has been confirmed that N-myc amplification,chromosome abnormality,and some certain gene mutations are related with neuroblastoma.However,since the development of molecular biology,some single nucleotide polymorphismes in certain genes have been established to play an important role in neuroblastoma.It is necessary to summarize the latest studies about single nucleotide polymorphism in neuroblastoma.

Among the genes involved in epilepsy,the SCN1 A gene represents one of the most commonly mutated human epilepsy genes, refers to be as super culprit gene, SCN1 A mutations cause epilepsy phenotype heterogeneity, diversity of clinical manifestations, the light performance of febrile seizures, it shows severe infant severe myoclonic epilepsy.By retrieving SCN1 A in gene mutation database, about 900 gene mutatation are associated with epilepsy syndrome.This article reviews the importance of SCN1 A gene mutation associates with epilepsy syndrome,and the importance of genetic screening SCN1 A.

This study explores the association between physician-patient communication and healthcare service quality,and relevant factors.The physician-patient communication belongs to medical behaviors,and plays a key role in the improvement of physician-patient relationship and the overall healthcare service quality.The consults of physician-patient communication were affected by many factors including physicians' attitude,and usage of words and behaviors,in which the positive attitude and behaviors are key solution to the improvement physician-patient relationship.Therefore the urgent matters are to strengthen standardized management of physician-patient communication,and set up related regulations and effective measure.

OBJECTIVE:To establish a RP-HPLC method for determination of the content of hesperidin in weisu gran?ules.METHODS:Symmetry C 18 (150mm?3.9mm,5?m)column;acetonitrile-water(19.5∶80.5),water containing phosphoric acid(800∶0.1)as mobile phase and detection wavelength was284nm.RESULTS:The calibration curve was linear in sample size range of hesperidin of0.0228?g～0.1596?g(r=0.9996).The average recovery was97.2%(RSD=1.1%,n=6).CONCLU_ SION:The method was simple and accurate,and can be used for quality control of weisu granules.

By analyzing the medical ethics and medical behaviors of the distinguished doctor Qiufazu,we can draw the conclusion that his medical ethics is the comprehensive outcome of his personal experience,the cultivation of traditional Chinese culture,and his interactions and exchange with medical teachers and fellow-students,all of which play a critical role in shaping his value of medical ethics.The medical ethics of Qiufazu can be regarded as precious spiritual treasure in medical field,which still has rich enlightenment on the self-cultivation and professional development of modern medical staff.

OBJECTIVE To investigate the genotyping of ?-lactamases and aminoglycoside modifying enzymes on Acinetobacter baumannii isolated in Shaoxing. METHODS Thirty nine strains of A.baumannii were isolated from hospitalized patients,and drug-resistant genes were detected by PCR. RESULTS The detection rates of ?-lactamases coding genes of TEM and OXA-23 groups were 33.3% and 51.3%,The detection rates of aminoglycoside modifying enzymes coding genes of aac(3)-Ⅰ,aac(6′)-Ⅰ and ant(3″)-Ⅰ were 64.1%,64.1% and 74.4%,respectively.The others were not found in all 39 isolates tested. CONCLUSIONS The study showed that it is more serious for A.baumannii carrying ?-lactamases and aminoglycoside modifying enzymes coding genes in Shaoxing.

OBJECTIVE To apply D-test for detection of inducible resistance of erythromycin to clindamycin in staphylococci and investigate their resistant rate to erythromycin and clindamycin. METHODS According to the standards of NCCLS to detect inducible resistance of erythromycin to clindamycin in staphylococci . RESULTS Co-resistance to erythromycin and clindamycin accounted for 50% and 22.8% in 77 strains of staphylococci (20 of S.aureus and 57 of coagulase-negative staphylococci). The rate of erythromycin resistance and clindamycin sensitivity accounted for 20% and 59.6%. D-test positive rate was 50% and 61.8% of which were erythromycin resistant and clindamycin sensitive respectively. CONCLUSIONS D-test for detection of inducible resistance of erythromycin to clindamycin in staphylococci should be checked in clinical microbiology laboratory in order to help physicians to select MLSb antimicrobial agents correctly.

ObjectiveTo investigate the outcomes of mother a nd baby smaller than 37 gestational age caused by preeclampsia. Method sThe data for 122 preterm birth that was single pregnancy with preecla mpsia in our hospital from January 1993 to December 2002 were collected. The pri nciple of diagnosis and treatment, the outcomes were analyzed retrospectively. T he 122 pregnant women were divided into 3 groups according to their gestational age, more than 28 weeks and smaller than 31 +6 weeks was the first group (28 cases), more than 32 weeks and smaller than 33 +6 weeks was the second grou p (26 cases), more than 34 weeks and smaller than 36 +6 weeks was the thir d group (68 cases). The data were statisted with SAS software.Results The earlier the pregnancy-induced hypertension happened, the earlier the preeclampsia occured, the mean time was 14 03 d, 16 85 d,22 22 d, respect ively, (P0.05), the outcomes of mothers were good. Increasing the gestational age under the cond ition that the occurrene of comptications was not increased, 60 64% pregnant wo men accepted the treatment of improving the maturity of fetal lung. There were n o differences among the three groups at the morbidity of perinatal SGA, intracra nial hemorrhage (P 0.05) .ConclusionWe could improve the outcomes of pret erm birth caused by preeclampsia by enhancing the perinatal care, treating and t erminating pregnancy activey Increasing the gestational age, improving the matur ity of fetal lung would decrease the morbidity of severe RDS and improve the pe rinatal outcome effectively.

arotid artery atherosclerosis is closely associated with ischemic stroke.Carotid artery intimamedia thickness is an important indicator of carotid artery atherosclerosis.Magnesium is involved in the in vivo metabolism of a wide variety of processes.Studies have shown that magnesium can decrease carotid intimamedia thickness.This article reviews the relationship between magnesium levels and carotid artery atherosclerosis in different populations.
