Objective: To observe the transfer efficiency of protamine-DOTAP/Chol liposome-oligodeoxynuleotides complex to SKOV3 cells. Methods; Synthesized NF-?B decoy ODNs or scrambled ODNs labeled by FITC on the 5'ends was mixed with rationic DOTAP/cholesteral liposome and protamine, making the charge ratio of positive: negative 4. SK-OV3 cells were transfected by the complex (1 ?mol/L) and the efficiency were measured by flow cytometry ( FCM) and fluorescence meter. The direct effect of NF-KB decoy ODNs transfer on the growth of SKOV3 cell line in vitro was measured by MTT method. Results: The efficiency of LPD transfer to SKOV3 cell line was 96. 41% , significantly higher than that of naked DNA transfer which was 12. 86%. The growth of SKOV3 cell line was not affected by 48h incubation after NF-KB decoy ODNs or scrambled ODNs transfection. Conclusion: LPD method is the one with high transfer efficiency not affected by NBS( newborn bovine serum) with possibility of use in vivo.

Because of the particularity and the complexity of integrated management of food, government regulators must perform the whole process of quality control and trace to evaluate and judge the merits of food instead of only depending on product standards.Quality metrics is a new concept for the food industry, and can be regarded as the comprehensive evaluation and measurement for product quality and the standard for judging the quality of food products.Request for Quality Metrics Guidance for Industry was issued, which not only established a new model for the quality control of pharmaceutical industry, but also provided a new way of quality management for the inspection organization.By introducing the contents of Request for Quality Metrics Guidance for Industry issued by the US FDA, on the basis of summarization and thought, the quality management and evaluation of pharmaceutical industry was compared, and the feasibility and applicability of quality metrics management in inspection and testing field, especially in food testing field was evaluated.In this paper, the concept of quality metrics was extended to the level of food inspection laboratory management with hope to provide ideas for the future development of food quality management model.

Objective To analyze the results of postoperative conventional radiotherapy supplemen- ted by stereotactic radiotherapy for glioma and with analysis of prognostic factors.Methods From Dec. 1998 to Dee.2004,143 patients with brain glioma were postoperatively treated with conventional radiotherapy supplemented by stereotactic radiotherapy.Steretactic radiotherapy of 5-7 Gy/fraction,to totally 5-7 fractions were added as boost to the GTV following the conventional radiotherapy.The conventional radiotherapy,ai- ming at the peri-tumoral subclinical micro-loci,was about 50 Gy.Results The KPS grades were 81?9, 71?9 in patients 3-6 month after treatment in contrast to that prior to operation (t=5.98,P<0.01 ).CR 39 patients (27.3%) ,PR 70 patients(49.0% ) ,NC 25 patients(17.5%),PD 9 patients(6.3%),with an effi- ciency rate of 76%.The 1-,3-,and 5-year survival rate was 56.6%,36.0% and 21.7%,respectively. Prognostic factor analysis showed that patients with low grade glioma had better survival time.Age,tumor site and dose,etc were unrelated to prognosis.Conclusion Stereotactic radiotherapy supplementing conven- tional radiotherapy is effective for postoperative brain glioma,which method not only shows excellence in physical dose distribution but strictly in accordance with the principle of radiobiology also.

Objective: In order to solve the problem of moisture absorption for Biantong Capsule, the extract granule of Chinese medicine is covered with HPMC for Biantong Capsule. Methods: Taking moisture absorption rate as measure index, various facters effected the moisture absorption rate, and the optimal coating process can be selected with well disturbed uniform design and computer analog test. Results: Under the condition of 25℃, relative moisture 75% and 100% respectively, the moisture absorption rate is lower than uncovered granules, the critic relative moisture of covered granules is greater than that of uncovered granules. Conclusion: Chinese medicine of Biantong Capsule covered with HPCM can be served as a good anti moisture method.

Aim To investigate the inhibitory effect of schizandrin B( SchB) on ultraviolet radiation b ( UVB) radiation-induced apoptosis of HaCaT cells. Methods Methyl thiazolyl tetrazolium ( MTT ) assay was used to examine the effect of SchB on cell viability recovery. Cell apoptosis and necrosis were measured by Ho-chest33342 staining. The p53, p21 and Caspase-3 mRNA expressions were examined by RT-PCR. Results In this study, we found that Sch B attenuated UVB-in-duced toxicity in HaCaT cells. Through Hoechst 33342 stain, we visualized that SchB could inhibit UVB-in-duced HaCaT cell death. The result demonstrated that p53 , p21 and Caspase-3 mRNA levels decreased com-pared with the control group. Conclusions Sch B at-tenuates the UVB-induced toxicity of HaCaT by inhibi-ting apoptotic gene expression. It plays a role in anti-photoaging.

Objective To explore the protective effect of schisandrin B (SchB) on the permanent damage of human keratinocytes (HaCat) induced by long wave ultraviolet (UVA),and its possible mechanism thereof. Methods After HaCat was treated by 5 J/cm2 UVA, different concentrations of SchB (0.1, 0.01, 0.001 and 0.000 1μmol/L) were used to treat HaCat cells. The levels of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activity, lactate dehydrogenase (LDH) and NO content were detected. Results The levels of SOD and GSH-Px activity were decreased, and he levels of LDH and NO content were increased in HaCat cells after being treated by UVA. The different concentrations of SchB showed significant ef-fects on the increased levels of SOD, GSH-Px activity and decreased levels of LDH and NO, and improved the survival rate of HaCat cells. The 0.001 μmol/L SchB showed the strongest protective effect. Conclusion The 0.001 μmol/L SchB showed the best effect on the damage of HaCat cells induce the UVA.

Objective To investigate the relationship between impaired fasting glucose(IFG) and the distribution of body fat in adolescents.Methods Stratified cluster sampling was used to select 3874 adolescents aged 13-18 years for this cress-sectional study.Measurements included height,weight,waist circumference,hip circumference and fasting plasma glucose (FPG).Family history of diabetes was determined by using a serf-administered questionnaire.Participants were divided into normal fasting glucose group(FPG<5.6 mmol/L,n=3738) and impaired fasting glucose group (5.6 mmol/L≤FPG < 7.0 mmoL/L,n=136) according to their FPG levels. Results (1) After adjusting for age and sex using covariance analysis,the impaired fasting glucose group showed increased levels of body mass index,weight circumference,waist/hip ratio,waist/height ratio,as compared to the normal fasting glucose group (P< 0.05).(2) After the age and gender were adjusted,body mass index,weight circumference,waist/hip ratio and waist/height ratio were positively correlated with FPG level (P<0.05).Among the partial relation coefficients, that between waist/height ratio and FPG(r'=0.0925) was the highest (3) In multiple regression analyses,age (β=-0.102,P<0.05),family history of diabetes (β=0.186,P<0.05) and waist/height ratio (β=0.842,P<0.05) were consistently associated with FPG.Conclusion Central obesity was an important predictor of IFG in adolescents.Waist/height ratio may be an useful index of central obesity and an important predictor of IFG in adolescents.
