Objective To explore the therapeutic effect of lung cancer Ⅳ recipe combined with chemotherapy on treating middle and advanced stages of non-small cell lung cancer (NSCLC) in the elderly.Methods A total of 77 NSCLC patients in middle and advanced stages aged 70 years and over who had heat-toxin syndrome in traditional Chinese medicine (TCM) were selected from Apr.2013 to Oct.2014 in our hospital.Patients were randomly divided into chemotherapy group (n=39) and chemotherapy + herbs group (n=38).Karnofsky assessment scale (KPS),effective rate,symptom and sign in traditional Chinese medicine,changes in the levels of high-sensitivity c-reactive protein (hs-CRP),carcino embryonic antigen (CEA),neuron specific enolase (NSE),tumor special growth factor (TSGF) were observed before and 1 and 56 days after treatment.Results There was no significant difference in effective rate between the two groups (P＞0.05).The KPS and symptom and sign in TCM were improved significantly in chemotherapy + herbs group as compared with chemotherapy group (36.7 ％ vs.26.5 ％,80.0 ％ vs.58.8 ％,respectively (x2 =2.721,6.731,both P＜0.05).There were no significant differences in hs-CRP,NSE,CEA,TSGF levels between two groups before and after treatment (P＞0.05),but hs-CRP level in both groups was decreased after treatment as compared to pre-treatment and the decvease was more obvious in chemotherapy + herbs group (51.47％ vs.23.77％,x2 =19.713,P＜0.05).Conclusions Lung cancer Ⅳ recipe can improve the main clinical symptoms,quality of life and tolerance to chemotherapy in NSCLC patients with heat-toxin manifestation in TCM.There is a correlation between heat-toxin syndrome and hsCRP level in NSCLC patients,which shows that hs-CRP probably is the material basis of the heattoxin syndrome in TCM.

OBJECTIVE: To evaluate the effects of NF-κB activation on the proliferation and apoptosis throughTLR4/MyD88 signaling pathway in human nasopharyngeal carcinoma (NPC) 5-8F cell lines. METHOD: TLR4 induced by LPS is inhibited by PE anti-human. Real-Time Quantitative PCR and Western blot were employed to evaluate the efficacy of mRNA level and protein expression. The growth inhibition rate of 5-8F by Celecoxib was evaluated with MTT method. The cell cycle and apoptosis were measured with flow cytometric method (FCM). RESULT: By using the specific inhibitor, the protein and gene expression of NF-κB and MyD88 were both significantly lower than the control group (P<. 05). Meanwhile, the down-rugulation of NF-κB could inhibit proliferation of NPC 5-8F cells and promote their apoptosis (P<0. 05). CONCLUSION By inhibiting TLR4 / MyD88 signaling pathway, the expression of NF-κB in NPC 5-8F cells could decrease, then the cell proliferation was inhibited and cell apoptosis was induced. The results showed that TLR4 / MyD88 / NF-κB induced by LPS is an important pathway in the genesis and development of NPC. This study provides evidence for targeting research of NPC.
