OBJECTIVE:To probe into the status quo and the trend of the utilization of the oral stasis-eliminating Chinese patent medicine in our hospital in order to provide scientific basis for rational use of this medicine.METHODS:The consumption amount and consumption sum of the oral stasis-eliminating Chinese patent medicine in our hospital during 2006-2008 were reviewed in respect of the DDDs and DDC using DDDs ranking method.RESULTS:During 2006～2008,the consumption amount of the oral stasis-eliminating Chinese patent medicine in our hospital had a steady increase,and the DDDs showed a good synchronism.CONCLUSION:The use of stasis-eliminating Chinese patent medicine is rational in our hospital.

A novel HBV integration site involved in hepatocarcinogenesis was investigated. The HBV DNA integration sites were detected by Alu-PCR in hepatocellular carcinoma tissues, matched surrounding liver tissues in 30 patients with hepatitis B-related hepatocellular carcinoma (HCC) and 3 cases of normal liver tissues. The integration sites and flanking sequences in human genome were sequenced and blasted, and the expression of integrated HBV genes was determined by reverse transcriptase-polymerase chain reaction (RT-PCR). The influence of the up-regulated expression of integrated genes on hepatocarcinogenesis was analyzed. Nineteen integration sites of HBV DNA into HCC tissues were obtained by RT-PCR and sequencing. These genes encoding proteins were: LOC51030, LOC157777, minichromosome maintenance complex component 3 associated protein (MCM3AP), MCTP1, SH3 and multiple ankyrin repeat domains 2 isoform 2, CCDC40, similar to HCG2033532, mitochondrial ribosomal S5 pseudogene 4. One of them was integrated into the intron of MCM3AP. RT-PCR demonstrated that the expression levels of MCM3AP mRNA in HCC tissues, matched surrounding liver tissues and normal liver tissues were in a descendent order. The ratio of MCM3AP mRNA to the GAPDH mRNA in these three tissues was 1.07375, 0.21573, 0.06747 respectively, with the difference being statistically significant among them (P<0.05). Meanwhile, the expression levels of MCM3AP mRNA from HCC tissues in which HBV DNA integrated into MCM3AP were still significantly higher than those without HBV DNA integrated into MCM3AP. It was concluded that the HBV DNA integration sites into human genome were random, and MCM3AP was a new site. The up-regulated MCM3AP mRNA may affect flanking sequences which promote the hepatocarcinogenesis.

Objective To explore the inheritance characteristics of SCN1A gene in familial severe myoclome epilepsy in infancy.Methods The clinical information and blood of the patients and their relatives who had febrile seizure(FS)or epilepsy history were collected.Blood genome DNA were extracted.All exons of SeN1A gene were PCR amplified and screened with denaturing high Performance liquid chromatography(DHPLC)technology,and sequence analysis was performed.Results Fourteen SME patients had FS or epilepsy family history.Five were found positive history in first class relatives and 2 of them had inherited mutations of SCN1A(C.4284+2T>C and e.1216G>T):Other9 were found positive history in second class relatives and 2 of them had de novo mutations of SCN1A.Condusions SCN1A is the pathogenic gene for SME.The same muatation of SCN1A gene can be related to different clinical phenotypes.SME patients whose first class relatives with FS or epilepsy history should be taken as the focus of SCN1A inherited mutation screening.

Objective To explore the regulative effect of α-Hederin on the proliferation and invasion of NSCLC and investigate its related molecular mechanism. Methods After A549 and HCC-1833 cells were treated with a concentration gradient of α-Hederin for 24 and 48 h, the OD_450nm was detected by using CCK8 assays, and the IC₅₀ was calculated.The A549 and HCC-1833 cells were divided into the blank control and α-Hederin groups in accordance with IC₅₀ values.Cell proliferation was detected by EdU assays, and cell cycle transformation and cell apoptosis were detected by flow cytometry.Cell mobility was detected by using Transwell and scratch assays.SREBP1 and FASN protein expression levels were detected through Western blot analysis, and cell lipid accumulation was detected via oil red O staining. Results The survival rate of lung cancer cells decreased significantly with the increase of α-Hederin concentration, and the IC₅₀ values of A549 and HCC-1833 cells at 48 h were 15 and 25 μg/ml, respectively.Compared with the blank control group, cells proliferation and migration were significantly inhibited, cells were blocked in the G₁/S phase, the apoptosis rate increased, and the protein expression and lipid accumulation of SREBP1/FASN significantly reduced after α-Hederin treatment. Conclusion α-Hederin can inhibit the proliferation and migration, G₁/S phase transition and induce the apoptosis of NSCLC cells and hinder the malignant progression of NSCLC by downregulating the expression of SREBP1 and FASN and reducing the accumulation of cell lipids.
