OBJECTIVE:To provide reference for rational use of oxycodone and acetaminophen in outpatient and emergency department. METHODS:By retrospective study,the application of oxycodone and acetaminophen in outpatient and emergency de-partment of our hospital during 2013-2015 was analyzed statistically. RESULTS:During 2013-2015,there were 22654 outpatient and emergency prescriptions of oxycodone and acetaminophen in our hospital. The prescription number,amount and consumption sum of oxycodone and acetaminophen were increasing year by year. Top 3 clinical departments of oxycodone and acetaminophen in the list of prescription number were orthopedics department(78.34%),emergency department(15.52%)and oncology department (2.09%). The age of patients using oxycodone and acetaminophen mainly aged 19-64 years old(78.62%);the ratio of male to fe-male was 1:1.08. The amount of oxycodone and acetaminophen was 5 mg,mainly 4 times a day(86.91%). In all kinds of diagno-sis,knee osseous arthritis (47.26%),pain in waist and lower extremities (6.18%) and abdominal pain in dispute (5.92%) were top three. CONCLUSIONS:A large amount of oxycodone and acetaminophen were used in outpatient and emergency department of our hospital during 2013-2015;there is unreasonable drug use so that we need to strengthen management and standardize drug use.

Trihydroxybenzoic acid dimmer is an anti-tumor compound which is separated from water-caltrop. This study is aimed to investigate its anti-proliferation effect on HL-60 cells and the possible mechanism of inducing apoptosis. MTT assay was used to test HL-60 cells proliferation. The apoptosis, ROS levels and the mitochondrial membrane potential were detected by flow cytometry. Cytochrome c released from mitochondria to cytosol fraction was detected by Western blotting. The activity of Caspase-9 and Caspase-3 were measured by colorimetric method. It was found to inhibit HL-60 cells proliferation in a dose and time-dependent manner. Compared with control group, it caused the increase of ROS levels and a concomitant dissipation of the mitochondrial membrane potential and induced cytosolic accumulation of cytochrome c and activities Caspase-9 and Caspase-3. Therefore it can be concluded that mitochondrial-dependent pathways was involved in its induction of apoptosis of HL-60 cells.

OBJECTIVETo investigate the effect of specific blockage of mutant p53 gene by individualized antisense RNA in vitro.

METHODSMutation status of p53 in human breast cancer cell lines was determined by immunocytochemical staining, PCR-SSCP and sequencing. Single strand antisense transcription system targeting specific p53 mutation site (mt-p53) was constructed, and corresponding antisense RNA was prepared. The hybridization of antisense RNA with its corresponding mt-p53 gene was confirmed by in-situ hybridization. Human breast cancer cells were transfected with antisense RNA by cationic liposome-mediated method. Time course of effects of antisense RNA was investigated by immunocytochemical staining and cell growth inhibiting assay. Expression of mt-p53 protein was examined by Western blot. Cell proliferation was evaluated by MTT assay and cell cycle distribution was determined by flow cytometry (FCM). Apoptosis was determined by TUNEL assay.

RESULTSMutation of p53 exon 8 was found in MDA-MB-231 cells and antisense transcription system (pGEM3zf (+/-) p53exon8) was then constructed successfully. In transfected MDA-MB-231 cells, hybridization signals were observed in cytoplasm. Fourth-eight hours after transfection, the antisense RNA (ASp53exon8'RNA) had a significant retarding effect on p53 related proliferation inhibition, along with a decrease of p53 protein expression.

CONCLUSIONSASp53exon8'RNA specifically blocks mt-p53 gene expression, resulting in an inhibition of MDA-MB-231 cell proliferation. Such an approach may be used as a therapeutic option against human malignancy.

OBJECTIVETo find a simple, fast, accurate, and quantitative PCR-based method for mutation detection, so as to identify mitochondrial DNA 11778 G-->A point mutation in patients with Leber's hereditary optic neuropathy (LHON).

METHODOn the basis of sequencing of mtDNA from LHON proband, M primer for mutation and N primer for normal were designed to be coupled with reverse primer respectively. Specific PCRs were done on an amplifying condition with high stringency such as a well controlled annealing temperature, low Mg2+ concentration and less thermal cycles. The objective pedigree includes 10 individuals, were against 40 normal control persons.

RESULTSDifferent ratios of indicative mtDNA 11778A-->G mutation were checked out from the proband, affected maternal members and a 10 year-old boy (up to now no appearance yet), whereas not appeared on normal spouses, paternal offsprings in the family, neither did on 40 controls.

CONCLUSIONThis site-specific PCR method is a kind of general mutation analysis way, without the restriction of existence of endonuclease site. It can be applied for the gene diagnosis of known-mutation hereditary diseases such as LHON.

OBJECTIVETo investigate the association between single nucleotide polymorphisms (SNPs) of casein kinase I gamma 2 (CSNK1G2) gene and children with familial febrile convulsions.

METHODSThe study samples were collected from unrelated Chinese Han population of Hebei province, including a cohort of 53 children with familial febrile convulsions(FC) and a control cohort of 101 individuals. Genotypes of SNPs rs2074882, rs740423, rs2277737, rs4806825, rs1059684 were typed by polymerase chain reaction-restriction fragment length polymorphism.

RESULTSThe frequencies of the five SNPs complied well with the Hardy-Weinberg equilibrium in FC group and normal group. The distribution of genotype and frequencies of alleles of the SNPs rs740423, rs2277737, rs1059684 in familial febrile convulsions group was significantly different from that in control group. No significant difference was observed in the distribution of genotypes and frequencies of alleles at SNP rs2074882 between two groups. Analysis on rs4806825 was not made owing to its less allele frequency.

CONCLUSIONThese data indicate that SNPs rs740423, rs2277737, rs1059684 of CSNK1G2 gene may contribute to familial febrile convulsions in children.
