OBJECTIVE:To evaluate the status and tendency of the application of antihyperlipidemics drugs in Chongqing area. METHODS: The use of antihyperlipidemics drugs in 28 hospitals of Chongqing from 2004 to 2007 was analyzed statistically in respect of the consumption sum, DDDs and DDC. RESULTS: The mean annual incremental ratio of the consumption sum of antihyperlipidemics drugs reached over 33.80%. Simvastatin has been dominated the first place over the 4 years in terms of consumption sum and DDDs; the consumption sum of atorvastatin has been on the rise but that of Gemfibrozil decreased year on year with mean annual decrement of 60%. CONCLUSION: Statins assumed a dominant position among all the antihyperlipidemics drugs used in Chongqing area and its use has great potential.

Aim: To study the distribution and excretion of baicalein and baicalin in rats. Methods: An LC/MS method was applied. Chromatographic separation was performed on a C_(18) column( 150 mm ×6.0 mm, 5 μm) with methanol-10 mmol/L ammonium acetate (containing 0. 5% formic acid) as the mobile phase. A trip-quadrupole tandem mass spectrometer was set in positive selected reaction monitoring mode. The sample was extracted with methanol-acetonitrile( 1:1) after the addition of phosphoric buffer solution and luteolin, which acted as the internal standard. The supernatant was evaporated to dryness, and the residual was reconstituted with mobile phase and analyzed. Results: The distribution profiles of the parent drug and its main metabolite showed two peaks between 20-40 min and 8-10 h after oral administration of baicalein, which fit the plasma concentration-time profile of baicalein in rats. At 20 min after the dosing, the concentration levels of baicalein were significantly higher than those of baicalin in stomach, liver and intestines, the converse result occurred in kidney. The excretion results showed that baicalin was the predominant excretion form in bile and urine, while baicalein was the negligible excretion form. There was more baicalein than baicalin in rat feces. Conclusion: Baicalein was absorbed and distributed quickly to various tissues and easily transformed to its metabolite at the same time.

The transcription factor of ethylene responsive factor binding protein (ERF) is belonged to AP2/ERF superfamily, which is known to be unique in plants. AP2/ERF proteins have important functions in the transcriptional regulation of a variety of biological processes related to growth and development, as well as various responses to environmental stimuli. An ERF gene from Salvia miltiorrhiza is cloned and divided into ERF gene family group VII of Arabidopsis and Rice. It contains a MCGGAI (I/L) motif referred to as CMVII-1 and a single intron in the 5'-flanking region of the AP2/ERF domain. Sequence analysis reveals that the region of second extron has abundant polymorphism sites. There are 21 single nucleotide polymorphism sites (SNPs) in the 264 bp region, among them, 14 SNPs are synonymous substitutions and 7 SNPs are non-synonymous substitutions. Though analysis of 181 samples from Shandong, Shaanxi and Sichuan Provinces, it reveals that each production area has its own special genotypes, 5 SNPs show significant difference. Cluster based on UPGMA method reveals that different populations from specific province have clustered together. It shows that SmERF gene will be a candidate molecular marker for the identification of Salvia miltiorrhiza from different areas.

Objective To identify the role of survivin and VEGF in angiogenesis of colorectal tumor by investigating tissue expression of survivin, VEGF and CD34 in human colorectal tumors. Methods Immunohistochemical staining for the paraffin sections by using the polyclonal antibodies of survivin, monoclonal antibodies of VEGF and CD34, was performed by the standard avidin-biotin-peroxidase technique. The percentage of positive cell and quantitative analysis were made by image analysis system, which also helped to calculate the amount of MVD. Results The immunoreactivity of survivin significantly increased in the transition from adenoma with low dysplasia to adenoma with high dysplasia (P <0.01). Similar changes in protein expression were observed for VEGF and MVD. The expression of survivin was closely related with that of VEGF. Both were positively correlated with MVD. Conclusion Survivin promotes angiogenesis of colorectal tumor together with VEGF. VEGF may be the potential causes of reexpression of survivin during colorectal tumorigenesis.

Objective To evaluate the middle and short-term effects of integrative cognitive training on mild cognitive impairments(MCI).Methods All the participants with MCI aged over 70 years were selected from one sub-district of Putuo District,Shanghai and divided into cognitive intervention group (n=46) and control group (n=35).The integrative cognitive training was conducted in 24 sessions for 12 weeks.All subjects were assessed by Neuropsychological Test Battery for Elderly (NTBE) and by a questionnaire of Shanghai Health Survey for the Elderly (VER2006)at baseline,follow-up and one-year follow up phases.Results At baseline phase,semantic relations test in NTBE was better (t=2.13,P=0.037),verbal fluency test (vegetables) in NTBE was worse(t =-2.25,P=0.038) in intervention group than in control group,while there were no significant differences in scores of other neuropsychological tests between intervention group and control group(all P>0.05).At follow up phase,16 subscales in reasoning test of NTBE were improved (t=-2.70,P=0.010)and 2 subscales were declined in cognitive intervention group(all P<0.05).9 subscales in semantic relations test of NTBE (t=-2.27,P=0.013) were improved and 5 subscales were declined in control group (all P< 0.05).Comparison between groups at one year follow-up showed that 5 subscales in reasoning test of NTBE (F=16.80,P=0.000) were better in intervention group than in control group(all P<0.05).General linear model (GLM) with repeated measures at three time points showed that 4 subscales in reasoning test of NTBE had a time-by group interaction (F=5.16,P=0.01).Conclusions Integrative cognitive training can improve cognitive function in patients with mild cognitive impairments,and the validity of reasoning ability can sustain one year.

The goal of the study was to investigate the protective effect and mechanism of Artemisia argyi ethanol extract on chemotherapeutic vancomycin (VAN)-induced acute kidney injury (AKI).The acute kidney injury model of male ICR mice was induced by intraperitoneal injection (ip) of VAN.Thirty mice were divided into the blank group, model group, high dose group, middle dose group and low dose group, which were given medicine by gastric perfusion (ig).Serum levels of cystain C (Cys C), blood urea nitrogen (BUN) and serum creatinine (Scr) were measured, which could reflect renal function of mice.Serum oxidative stress and inflammation indices were also determined, including muscular dystrophy association (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), tumor necrosis factor-alpha (TNF-α), Interleukin-1β (IL-1β), and high-sensitive c-reactive protein (hs-CRP).In addition, hematoxylin-eosin staining (HE) was employed for measuring the damage of renal tissues and the content of apoptosis b-cell lymphoma-2 (Bcl-2), Bcl-2 assaciated X protein (Bax) and caspase-3 were measured too.All results showed that Artemisia argyi extract exhibits protective effect on chemotherapeutic VAN-induced AKI, whose mechanism could be related to the oxidative stress, inflammatory reaction and apoptosis.
