AIM: To investigative the inhibitory effects of Paecilomyces cicadae polysaccharide (PcPS) against HBV in vitro, and the effects on the Toll like receptor 4 (TLR4) mRNA expression in HepG2.2.15 cell strain. METHODS: HepG2.2.15 cell strain was co-cultured in vitro with PcPS in different concentrations, and lamivudine (LMV) was applied as positive control. MTT assay was employed to detect the cytotoxicities of PcPS in vitro, when the HepG2.2.15 cells was used as target cells. The effects of PcPS on the secretion of HBsAg and HBeAg were assayed by ELISA method. Fluorescence quantitative-PCR (FQ-PCR) was used to detect the inhibitory effects of PcPS on the content of HBV-DNA and TLR4 mRNA in HepG2.2.15 cells. RESULTS: The inhibitory effects of PcPS on the HBsAg and HBeAg were observed and the maximum inhibitory ratio up to 44.8% and 31.0%, respectively. The same inhibitory effects of PcPS on the HBV-DNA replication and TLR4 mRNA expression in HepG2.2.15 cells were also found. CONCLUSION: A certain concentration of PcPS significantly inhibits HBV replication in vitro.

Results The hemoglobin(Hb),albumin(ALB),body mass and body mass index(BMI)were (130.50 ±17.80)g/L, (41.02 ±5.68)g/L,(61.29 ±8.75)kg,(22.36 ±2.78)kg/m2 respectively at admission;(115.90 ±19.00)g/L, (37.94 ±5.55)g/L,(59.95 ±9.05 )kg,(21.86 ±2.86)kg/m2 respectively during the course of radiotherapy;(110.40 ±19.40)g/L,(36.91 ±5.30)g/L,(58.91 ±9.30)kg,(21.48 ±2.99)kg/m2 respectively at the end of radiotherapy.At different stages of radiotherapy,the nutritional index gradually decreased,the Hb was lower in the middle of the radiotherapy than on admission,the difference was significant(t =8.611,P <0.05).The Hb in the late stage of radiotherapy was lower than the middle,the difference was significant(t =2.492,P <0.05).Although the ALB in the latter stage of radiotherapy was lower than the middle,but the difference was not statistically significant (t =1.464,P >0.05),and the difference was significant compared with on admission(t =4.815,P <0.05).The weight of the patients in the middle period of radiotherapy was less than the time of admission,but the difference was not statistically significant(t =0.781,P >0.05).The weight of patients in the late stage of radiotherapy was lower than the medium term,but the difference was not statistically significant as well(t =0.601,P >0.05),and there was no significant difference compared with on admission(t =1.382,P >0.05).The BMI of the patients with radiotherapy was lower than that at the time of admission,the difference was not statistically significant(t =0.091,P >0.05).The BMI of patients with radiotherapy was lower than that in the medium term,whereas the difference was not statistically significant(t =0.690,P >0.05),and the difference was not statistically significant compared with on admission(t =1.599,P >0.05).The Hb (F =16.643,P =0.000)and ALB(F =7.736,P =0.001)decreased significantly in particular.Conclusion The risk of malnutrition in patients with lung cancer is exist during radiotherapy and chemo-therapy,and it is obvious in the middle -late stage,the changes of physical and biochemical indexes have been appeared,and among them,Hb and ALB are the most obvious,so should be monitored and managed cause these data varied significantly.

AIM: To explore the immunomodulatory effect of paecilomyces cicadidae polysaccharides (PCPS).METHODS: Subcutaneous injection with 50, l00, 200 mg/kg of PCPS were given in the back of the rats everyday for l5 days. The number of white blood cells (WBC) was counted. The activities of acid phosphatase (ACP) and lactase dehydrogenase (LDH)in liver, kidney, spleen and thymus were detected by automatic biochemistry analyzer.
