Argonaute 1 (AGO1) is a core component of the RNA-induced silencing complex (RISC) which plays a crucial role in small RNA-mediated gene silencing. AGO1 gene has been characterized in various plants, such as Arabidopsis and rice. However, there is no information about AGO1 in the medicinal plant species, Panax ginseng. Using the rapid amplification of cDNA ends technology (RACE), we cloned full-length PgAGO1 cDNA from Panax ginseng. It is 3 776 bp in length, including 204 bp of 5' UTR, 254 bp of 3' UTR, and 3 318 bp of ORF encoding 1106 amino acids. The molecular weight (MW) and theroretical isoelectric point (pI) of the deduced PgAGO1 protein is 122.22 kDa and 9.71, respectively. PgAGO1 shares 91.72% similarity with Arabidopsis AtAGO1 and contains three consered domains, including DUF1785, PAZ and Piwi, suggesting it is an authentic AGO. PgAGO1 was expressed in all of the tissues analyzed with the highest level in flowers and the lowest level in roots. The results provide useful information for further elucidating the function of AGO1 in Panax ginseng.

Aim To discuss the effect of Danhong in-jection(DHI) on hyperlipidemia in rats and its possible mechanism. Methods The hyperlipidemia model of rats were induced by high fat diet. The protein expres-sion of adenosine 5'-monophosphate-activated protein kinase(AMPK), p-AMPK, cholesterol-binding ele-ment binding protein (SREBP-1), adenylate-activated protein kinase carboxylasecetyl-CoA(ACC) and p-ACC in liver were detected using Western blot. Results The protein expression levels of AMPK, SREBP-1 and ACC significantly decreased (P<0.05), but the pro-tein expression levels of p-ACC and p-AMPK signifi-cantly increased (P<0.05). Conclusions Danhong injection can reduce the activity of SREBP-1 and ACC by enhancing the activation of AMPK, and effectively reduce the blood lipid level of hyperlipidemic rats by promoting fatty acid oxidation and reducing lipid depo-sition.

Objective To investigate the effects of transcription factor 2(TCF2) overexpression on insulin resistance in HepG2 cells. Methods HepG2 cells were treated with high concentration of insulin(1×10-8mol/L) for 24 hours to induce insulin resistance (IR). Cells were divided into four groups:control group,IR group,IR+vector group and IR+TCF2 overexpression group. RT-qPCR and Western blot were performed to detect the expres-sion of TCF2. Glucose consumption and glycogen synthesis were assayed by glucose oxidase method and anthrone method respectively. Cell viability was evaluated by MTT assay. The activities of hexokinase and pyruvate kinase were detected by colorimetry. The protein level of IRS-1 and GLUT4 was detected by Western blot.Results Com-pared with control group,the decreased glucose consumption was observed in IR group(P＜0.05),indicating that insulin-resistance model was established successfully. The mRNA and protein expression of TCF2 was remarkably down-regulated in IR group as compared with control group. Compared with IR group,overexpression of TCF2 sig-nificantly improved glucose consumption, liver glycogen content, and the activities of hexokinase and pyruvate kinase (P＜0.05). Moreover,TCF2 overexpression up-regulated the protein expression of IRS-1 and GLUT4 (P＜0.05).Conclusions TCF2 overexpression ameliorates insulin resistance of HepG2 cells.

OBJECTIVETo explore the value of trisomy 22 ( +22) in the diagnosis of inv(16) acute myeloid leukemia (AML).

METHODSInterphase fluorescence in situ hybridization (FISH) was performed in 18 AML patients with +22. The probe was two-color break apart probe for CBFbeta with SpectrumRed on the centromeric side and SpectrumGreen on the telomeric side. The FISH results were compared with that of R-banding conventional cytogenetics (CC). Multiplex FISH (M-FISH) was used to analyze the relationship of +22 and inv(16).

RESULTSCC revealed inv(16) in none of the 18 AML, with +22, but FISH revealed inv (16) in 11 of them and del( 16) (q22) in one. As CC results, 9 of the 11 cases were sole +22, one complicated with trisomy 8, and one del(16) (q22). Four patients with +22 and inv(16) were analyzed by M-FISH and revealed +22 only.

CONCLUSION+22 can be regarded as an important marker for the diagnosis of inv(16) AML.

Through the participation in the formulation of drug treatment by clinical pharmacists, GLP-1 preparation was used for hypoglycemic treatment, and the effect was promising. There was no significant change in the patients' liver function. By actively participating in the formulation of glucose-lowering therapy, clini-cal pharmacists can improve the effectiveness and safety of drug treatment.

To explore the method of identifying nursing-related patient safety events,types,contributing factors and evaluate consequences of these events in hospitals of China,incident report program was established and implemented in 15 patient units in two teaching hospitals of China to get the relevant information.Among 2935 hospitalized patients,141 nursing-related patient safety events were reported by nurses.Theses events were categorized into 15 types.Various factors contributed to the events and the consequence varied from no harm to patient death.Most of the events were preventable.It is concluded that incident reporting can provide more information about patient safety,and establishment of a program of voluntary incident reporting in hospitals of China is not only urgent but also feasible.

Objective To investigate the effect calcitriol combinating cisplatin on the human endometrial cancer ( HEC -1-A) transplanta-tion tumor of athymic mouse.Methods The HEC-1-A cell line was cultured in vitro.The thymic mouse with successfully tumor burden were divide into four groups:the control group (0.9%NaCl 0.25 mL), cal-citriol group (0.05 μg) , cisplatin group (50 μg) and combinating ( cal-citriol plus cisplatin ) therapy group.All of the four groups were treated once a week until 5 weeks.Results The difference of transplantation tumor volume between three therapy groups and control group is signifi-cant ( P<0.05 ).The apoptosis rate of the control , cisplati , calcitriol and combinating groups were ( 1.45 ±0.23 )%, ( 25.62 ±1.16 )%, (22.52 ±1.25 )%and (31.59 ±1.93 )%, respectively.There was sig-nificant statistical difference between combination group with the other three groups ( P<0.05 ).The mRNA expression level of Bcl -2 and Bax among the three therapy groups compared with control group were signifi-cant ( P <0.05 ).Conclusion Calcitriol had a strong anti -tumor effect in HEC-1-A transplantation tumor , the anti-tumor mechanism may associate with the Bax/Bcl-2 pathway induced HEC -1-A tumor cell apoptosis.

OBJECTIVEMethylmalonic acidemia complicated with homocysteinemia, cblC type, is the most common inborn error of cobalamin metabolism. The gene MMACHC (OMIM 277400) is located on chromosome 1p34.1 with four coding exons and a 5th non-coding exon. It encodes for a protein with 282 amino acid residues. So far, more than 40 mutations have been detected, in which 271dupA (R91KfsX14) is the hot spot of MMACHC gene. However, there have not been relevant reports in China. The present study aimed to identify the mutation types of MMACHC gene and analyze the genotype-phenotype correlations in Chinese patients.

METHODThe diagnosis of this disease mainly depends on the measurement of C3 propionylcarnitine, C3/C0 (free carnitine) and C3/C2 (acetylcarnitine) in the blood by tandem mass spectrometry, the detection of methylmalonic acid in the urine by gas-chromatography mass spectrometry, the determination of total homocysteine in the serum, and the loading test of vitamin B12. The entire coding region of MMACHC gene was screened by polymerase chain reaction (PCR) combined with DNA direct sequencing in 28 Chinese patients. Genomic DNA was extracted using phenol-chloroform method from the peripheral blood leukocytes of each patient. PCR amplification products were checked by 1.8% agarose gel electrophoresis and were subsequently sequenced with both the forward and reverse primers. Mutational analyses were performed using normal human genomic MMACHC sequence as a reference (GenBank ID: 25974).

RESULTIn this study, ten mutations were identified in 27 of 28 Chinese patients. Most of them were located in exons 3 and 4 (91.3%). We detected four mutations reported, which were 609G>A (W203X), 217C>T (R73X), 271dupA (R91KfsX14), and 394C>T (R132X), and six novel mutations, which were 1A>G, 365A>T, 658_660delAAG, 301-3_327del 30, 567_568insT, and 625_626insT. The 609G>A (W203X) is the most common mutation, which was detected in 30 of 56 alleles (53.6%), including 10 homozygote mutations and 10 heterozygote mutations. In addition, three gene polymorphisms were detected, namely, -302T>G (rs3748643), -234A>G (rs3728644), and 321G>A (rs2275276). These mutations include missense mutations, nonsense mutations, duplication, deletions, and insertions.

CONCLUSIONIn this study, we found a part of gene mutations spectrum in Chinese patients with methylmalonic acidemia and homocysteinemia, in which the 609G>A (W203X) may be the hotspot mutation of MMACHC gene. This would be helpful in the prenatal diagnosis and gene screening programs of methylmalonic acidemia and homocystinemia.
