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: 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.

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.

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 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 explore the preventive and therapeutic effects of Compound Zhuye Shigao Granule (CZSG), a compound Chinese herbal medicine, on radiation-induced esophagitis in rats. Methods: Fifty-six Wistar rats were randomly divided into 5 groups: normal control group (8 rats), model group (12 rats), and high-, medium- and low-dose CZSG groups (12 rats in each group). The rats in the normal control and model groups were given normal saline 10 mL/kg body weight and those in the CZSG-treated groups were given solution of CZSG at doses of 1.15, 2.30, or 4.60 g/kg body weight respectively by intragastric administration once a day for 7 days. Then esophagitis was induced by local irradiation of (60)Co ray (490.25 cGy/min, totaled 30 Gy). The administration was continued for another 7 days or 14 days, meanwhile body weight and daily food intake of the rats were recorded. Seven days after the irradiation, 4 rats in each group were sacrificed under anesthesia, then, the esophageal tissue was obtained for histopathological examination and the degrees of esophageal tissue injury and neutrophil infiltration were scored. Fourteen days after the irradiation, all the survival rats were dealt in the same way. Results: (1) Seven days after the irradiation, the esophageal tissue sections in the model group showed typical histopathological changes of radiation-induced esophagitis, whereas in the CZSG groups the histopathological changes were lessened dose-dependently and in the high-dose CZSG group the esophageal tissue remained basically intact. (2) The scores of esophageal tissue injury and cellular infiltration in the high- and medium-dose CZSG groups were both significantly less than in the model group (P<0.05). (3) The body weight of the rats increased in the normal control group, whereas it decreased obviously in the model group. In the medium- and high-dose CZSG groups, it did not decrease significantly. The decrease of body weight in the high-dose CZSG group was less than that in the model group (P<0.05). (4) Compared with the normal control group, the daily food intake was reduced in the other groups. However, it was significantly greater in the low, medium- and high-dose CZSG groups than in the model group (P<0.05). Conclusion: In rats with radiation-induced esophagitis, CZSG can effectively relieve the esophageal tissue injury and cellular infiltration, increase daily food intake, and prevent rats from lose of body weight dose-dependently, which show that CZSG has the preventive and therapeutic effects for radiation-induced esophagitis in rats.
