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.

Elderly acute myeloid leukemia (AML) accounted for 35 % of all AML with the increased incidence year by year, and the median onset age is 67 years old. Generally, AML patients require strong chemotherapy, but older patients often cannot tolerate intense chemotherapy due to the viscera dysfunction. It is still lack of unified treatment clinically. Reports on treatment of elderly AML in the 57th American Society of Hematology (ASH) annual meeting covered multiple fields, in which the traditional induction chemotherapy, demethylation drug alone or in combination with other drugs, and novel drugs were an involved. This article reviewed the latest research on the elderly AML in the 57th ASH annual meeting.

Asphyxiation by an inhaled foreign body is a leading cause of accidental death among children younger than three years.The species of foreign body aspiration are many and varied.Immediately after inhalation the child starts to cough,wheeze,or have laboured breathing.The clinical manifestation will be different when foreign body stays in different part of bronchial tree.It's extremely easy to cause misdiagnosis.No matter whether aspiration or not,bronchoscopy should be taken.The bronchoscopy is not only the means of diagnosis,and removes the foreign body at the same time which helps to treat timely.

Objective To investigate clinical effect of pinaverium bromide combined with probiotics in the treatment of patients with irritable bowel syndrome (IBS).Methods 156 patients with IBS were randomly divided into observation group and control group.Cases in control group received pinaverium bromide tablets,and cases in observation group received bifid triple viable capsule plus pinaverium bromide tablets.Duration of treatment was 4 weeks in both groups.Clinical efficacy was evaluated after treatment.Results Total effective rates of observation group and control group were respectively 85.9％ and 70.5％.Total effective rate of observation group was significantly better than that of control group(x2 =8.557,P ＜ 0.05).The systolic pressure of anorectum was significantly lower than that of control group after treatment(t =4.432,P ＜ 0.01),but resting pressure and diastolic pressure were not significantly different after treatment(t =0.812,0.142,all P ＞ 0.05).First sensation volume,defecating sensation volume and pain volume in observation group were significantly lower than those in control group (t =3.440,4.671,3.697,all P ＜ 0.01).Conclusion Treatment of IBS with pinaverium bromide combined with probiotics is effective,and it can improve the anorectal dynamic and isceral sensitivity in patients with IBS.

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.

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.
