OBJECTIVE:To establish the quality standard for Anti-virus chewable tablet. METHODS:TLC was used for the qualitative identification of Forsythia suspensa,Anemarrhena asphodeloides and Pogostemon cablin in Anti-virus chewable tablet, and HPLC was conducted to determine the content of forsythin in F. suspensa. The column was Diamonsil C18 with mobile phase of acetonitrile- water (20∶80,V/V) at the flow rate of 1.0 ml/min,the detection wavelength was 230 nm,column temperature was 25℃,and injection volume was 10μl. RESULTS:The test sample and the reference sample displayed same color spots on the cor-responding position in TLC diagram. The linear range of forsythin was 0.053 5-2.675 μg(r=0.999 9);RSDs of precision,stabili-ty and reproducibility tests were no more than 1.74%;average recovery was 98.94%(RSD=1.84%,n=6). CONCLUSIONS:The method is simple,rapid,accurate,reliable and reproducible,and can be used for quality control of Anti-virus chewable tablet.

The relationship between vascular endothelial growth factor-C (VEGF-C)/vascular endothelial growth factor receptor 3 (VEGFR-3) expression and clinicopathologic features of the patients with non-small cell lung cancer (NSCLC) was investigated. The expression of VEGF-C and VEGFR-3 was assessed in 65 patients with NSCLC by immunohistochemistry. The significance of VEGF-C and VEGFR-3 expression was analyzed statistically. The results showed that VEGF-C and VEGFR-3 were highly expressed in cytoplasm and membrane in lung cancer tissues with the positive rate being 55.4 % and 52.3 % respectively, while there was no expression in the normal lung tissues. The expression of VEGF-C was significantly increased in adenocacinoma as compared to other types of NSCLC (P<0.05). The VEGFR-3 expression was closely related with lymph node metastasis (P<0.01) and TNM stage (P<0.05). There was a positive correlation between the VEGF-C and VEGFR-3 expression in NSCLC patients (r=0.658, P<0.01). It is suggested that VEGFR-3 plays an important role in the lymphatic metastasis of NSCLC. The interaction between VEGF-C and VEGFR-3 may be deeply involved in the mechanism of lung cancer metastasis.

Objective To analyze the treatment results of intracavitary hyperfractionated brachytherapy for nasopharyngeal carcinoma and to determine the optimal dose of external radiation. Methods From February 1996 to June 1998, 128 patients with T1 2 nasopharyngeal carcinoma were treated with external radiotherapy followed by intracavitary brachytherapy. The majority of them had residual tumor less than 10 mm after external radiotherapy. The external radiation doses were divided into 3 groups: 56 Gy, 60 Gy and 66 Gy. Brachytherapy was delivered with 2.5 3.0 Gy per fraction, 2 fractions a day with an interval of 6 hours. The total doses ranged from 12 to 24 Gy with a median of 18 Gy. Results The disease free survival rates at 3 and 4 years for all patients were 84.2% and 74.9%, respectively. The corresponding local relapse free survival rates were 97.1% and 92.7%, respectively. The 3 year disease free survival rates and local relapse free survival rates were 83.6% and 100% for 56 Gy group, 88.4% and 90.9% for 60 Gy group, and 84.6% and 93.3% for 66 Gy group, respectively,all with differences in significant. Radiation complications were rare. Conclusions We suggest that patients with residual tumor less than 10 mm after external radiotherapy should receive intracavitary brachytherapy as a boost. The dose of external radiotherapy for T1 2 stage NPC can be decreased to 56 Gy.

Objective To study the results of external beam radiotherapy plus 192 Ir hyperfractionated high dose rate interstitial brachytherapy (HHDR-IBT) for cancer of the oral cavity and oropharynx. Methods Fourty-eight patients with cancer of the oral cavity and oropharynx were treated by external beam radiotherapy (T 1,T 2 30～50 Gy,T 3,T 4 50～60 Gy) followed by 192 Ir HHDR-IBT delivering 15～35 Gy (30～35 Gy for T 1,T 2 and 15～30 Gy for T 3,T 4 in 250～350 cGy per fraction,two fractions per day). Over 3～5 days. Results The complete response rates at 3 months were T 1100% (5/5),T 2 85%(23/27),T 3 46%(6/13),T 4 0%(0/3) and the partial reponse rates:T 2 15% (4/27), T 3 54%(7/13), T 4 100%(3/3). The 3-year survival and disease-free survival rates were 79.4% and 55.8%,respectively.Multivariate analysis showed that TNM stage and pathalogic type were prognostic factors.Conclusions Carcinoma of the oral cavity and oropharynx treated with external beam radiotherapy combined with 192 Ir hyperfractionated high dose rate interstitial brachytherapy ia able to give a good local control for T 1,T 2 lesions with good functional preservation. For T 3,T 4 lesions,this method is able to offer a high palliation.

Objective To study the induction of IL-6 on expression and activity of tissue factor (TF)in peripheral blood monocytes(PBMCs).Methods rhIL-6 100 ng/L and rhIL-6 100 ng/L+ rhIL-6 MoAb 10?g/L were used respectively to stimulate the PBMCs for 24 h,PBMCs without any stimulation as control group,to study the changes of antigen content,mRNA expression and the ac- tivity of the TF.Results The antigen content,mRNA expression and activity of TF were increased significantly in 100 ng/L rhIL-6 group as compared with rhIL-6 100 ng/L+rhIL-6 MoAb 10?g/L and control groups(P＜0.01).Conclusions rhIL-6 can induce the increase of antigen expression,activity and mRNA expression in PBMCs,and these effects can be suppressed successfully by rhIL-6 MoAb. This study demonstrated that there was potential relations between cytokines and thrombogenesis, which may play an important role the pathogenesis of chronic rejection.

Objective To observe the effect of transfer factor on immunity in patients with varruca plana and the clinical effect of treatment. Methods Sixty patients with varruca plana were randomly divided into a treatment group (treated with transfer factor) and a control group (treated with routine therapy). Before and after the treatment, T-lymphocyte subgroups in peripheral blood of all the patients were determined by flow cytometry and serum levels of interleukin-10 (IL-10)and in-terferon-gamma (INF-γ)were detected by ELISA. The same detections were done to the twenty healthy volunteers as healthy controls. Results Effective rates in the treatment group and control group were 76.67 % and 43. 33 %, respectively (x2=5. 63,P<0.05). Decrease of CD3+ cells, CD4+ cells, CD4+/CD8+ ratio and increase of CD8+ cells were found in varruca plana group as com-pared with the healthy controls(P<0.01 ). After the treatment of transfer factor, increase of CD3+ cells ,CD4+ cells (P<0.05), CD4+/CD8+ ratio (P<0. 01)and decrease of CD8+ cells(P<0.01)were found in the treatment group as compared with those before treatment, while there were no significant difference in the control group before and after the treatment. Higher IL-10 and lower INF-γ in serum were found in varruca plana group as compared with the healthy controls (P<0.05). After the treat-ment of transfer factor, decrease of IL-10 and increase INF-γ in serum (P<0. 05)were found in the treatment group as compared with those before treatment, while there were no significant difference in control group before and after the treatment. Conclusion The results reveal that immunity is im-paired in patients with varruca plana. Transfer factor can enhance the immunity of the patients. Therefore, varruca plana patients treated with transfer factor receive better effects.
