B-Raf kinase (BRAF) gene is a driver mutation,and is an effective target in the treatment of non-small cell lung cancer (NSCLC).Studies have shown that BRAF inhibitors are effective for treatment of NSCLC with BRAF mutant.It is important to understand the clinicopathologic features and the research progress of BRAF inhibitors for the individual treatment of NSCLC.

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs)and anti-angio-genic drugs have individually demonstrated clinical benefit in the treatment of patients with advanced non-small cell lung cancer (NSCLC).Recent studies demonstrate that the combination of anti-EGFR and anti-angiogene-sis can more significantly enhance clinical benefit,and even can remit EGFR-TKIs resistance in the treatment of advanced NSCLC.According to the different kinds of anti-angiogenesis drugs,recent clinical studies mainly include the combination of anti-vascular endothelial growth factor monoclonal antibody bevacizumab plus EGFR-TKIs and multi-targeted receptor anti-angiogenic tyrosine kinase inhibitor plus EGFR-TKIs,and the for-mer results show a more significant improvement in terms of safety and efficacy in the treatment of advanced NSCLC.Therefore,the combination of bevacizumab plus EGFR-TKIs can be used as a new treatment standard in the treatment of some patients with NSCLC.

Objective To establish the HPLC fingerprint of cultured Cordyceps militaris. MethodsHPLC Method was used for the determination of C. militaris on Agilent ZOBAX SB-Aq C18 column (250 mm?4.0 mm, 5 ?m), and measuring with methanol 5%—60% in 30 min as elution detective wavelength at 260 nm, injection sample of 1.0 ?L and flow rate of 1.0 mL/min. The systematic optimized design of the chromatographic conditions, such as supersonic extraction, mobile phase, and detective wavelength as well was carried out. Results Fingerprint consisted of 11 common peaks and the result of methodology determination fitted to the related standards. The evaluation of cultured C. militaris by systematically comparing chromatograms with a professional analytical software recommended by National Institute for the Control of Pharmaceutical and Biological Products has been established. Conclusion The method is accurate, simple, and useful for the quality control of cultured C. militaris.

Fatty acid synthase is the key enzyme which catalyzes the de novo synthesis of long-chain fatty acids from acetyl-CoA and malonyl-CoA.Only recently has it been appreciated that C75,the inhibitor of fatty acid synthase can make mice lose weight via reducing food intake and increasing energy consumption.The present paper reviews the potential mechanism by which the inhibitor of fatty acid synthase may influence the expression of hypothalamic neuropeptides mediating the behaviour of food intake in central nervous system and decrease adipose sediment or increase energy production.

ObjectiveTo observe the status and related factors of depression symptoms in elders.MethodsRandomized multi-stage sampling method was used to select subjects.504 elders ( aged ≥65 years) in Jining were investigated and assessed by using the scales of Geriatric Depression Scale15 ( GDS-15 ),Katz-activity of daily liying (Katz-ADL) and Lawton instrumental ADL (IADL).ResultsThe GDS scores of males (2.24 ±2.12 ) were significantly lower than that of females ( 3.35 ± 3.49) ( t '=4.236,P ＜ 0.01 ).There were significant differences in GDS scores among different subgroups of age,single or not,physical activity,sleep quality,self-reported health,living condition,economic status and lonely feeling.GDS scores were significantly correlated to lonely feeling,IADL,living condition,economic status,self-reported health and age (F =27.47,P ＜ 0.001 ; R2 =0.372,R'2 =0.358 ),with the total contribution of 35.8％.ConclusionAmong elders,the main factors influencing depression symptoms are lonely feeling,IADL,female,health condition,economic condition and single,respectively.Enhancing IADL of elders can contribute to reduce the risk factors of depression.

Objective To analyze the correlation between chronic diseases,depression and activities of daily living (ADL) in the elderly,and to explore the risk factors of depressive symptoms and ADL.Methods Randomized multi-stage sampling method was used to select 504 elderly (aged ≥65 years old) in Jining City.The participants were then investigated and assessed by using Geriatric Depression Scale15,Katz-Activity of Daily Living (Katz-ADL) and Lawton instrumental ADL (Lawton-IADL).Results The prevalence of chronic diseases was 74.01％ among the elderly who lived in Jining City.The positive rate of depressive symptom was 7.14％ and the rate of ADL or IADL limitation was 19.05％ and 66.67％,respectively.The positive rate of depressive symptom and the rate of ADL or IADL limitation of the male were lower than those of female (x2 values were 18.15,12.31 and 30.18,respectively; all P＜ 0.05).The number of chronic diseases was a risk factor of depressive symptom and ADL limitation (odds ratio (OR) =1.71 or 1.53,respectively).ADL and IADL limitations were also the risk factors of depressive symptom (OR =3.15 or 9.36,respectively).Over adjustment of gender and age,the impact of the number of chronic diseases on depressive symptom,ADL and IADL and the influence of ADL and IADL limitations on depressive symptom showed no statistical significance.Conclusions Gender and age may be fundamental risk factors of depressive symptom and ADL and IADL limitations in the elderly.Family members and society workers should improve ADL and positive emotion and reduce the likelihood of depressive symptom among aging population.

Connexin (Cx) is the main component of gap junction channels, which is essential for intercellular communication between adjacent cells.Cx plays an important role in regulation of the growth, differentiation and apoptosis of cells and is closely related to tumor formation and development.The expression of Cx appears to be different in different stages of tumor development, and the regulatory mechanism of Cx is also involved in many aspects.In this paper, recent advances in the studies on Cx are reviewed, including the relationship between Cx and development of tumor, the basic mechanism of Cx, as well as its applications in antitumor-drug screening and tumor therapy.

Objective To observe the effect of fluvastatin(Flu) on differentiation and induction of human promyelocytic leukemia HL-60 cells and provide the theoretical foundation for treatment of human promyelocytic leukemia.Methods The cultured HL-60 cells were treated with 20 ?mol?L-1 Flu,the morphological changes of the cell differentiation were examined.The NBT reduction capability was detected in HL-60 cells treated with Flu for 72 h.After HL-60 cells were treated with 20 ?mol?L-1 Flu for 5 d,they were stained with non-specific esterase and the percentage of differentiation cells was analyzed.Results The HL-60 cells treated with Flu showed smaller cell body,reducing proportion of nucleus to cytoplasm,the nucleus tortuosity,fold or sublobe.There were specific granules and vacuoles in cytoplasm,displaying that some cells had differentiated to relative mature cells.As compared with control group,the NBT reduction capability in HL-60 cells treated with Flu for 72 h was significantly higher than that in control cells(P

Immunotherapy is revolutionizing the treatment of non-small cell lung cancer (NSCLC).Programmed cell death protein 1 (PD-1) and programmed cell death ligand 1 (PD-L1) monoclonal antibodies have recently led to significant and durable improvements in the clinical outcome of NSCLC,and the anti-PD-1 antibody has been approved to use in first-line and second-line treatment of NSCLC.However,there are still many problems to be solved.The role of PD-L1 as a predictive biomarker remains unclear.Combination treatment models are being explored.This review summarizes the clinical efficacy,drug adverse reaction,combined treatment,and potential immune biomarkers of anti-PD-1/PD-L1 antibody research progress in the treatment of NSCLC.
