ABSTRACT
Objective:To investigate the efficacy of β-elemene combined with gefitinib in the treatment of advanced lung adenocarcinoma patients with slow progression after first-line gefitinib treatment and its effects on quality of life and immune function.Methods:A prospective cohort study design was used to enroll patients with advanced lung adenocarcinoma who met the inclusion criteria from June 2017 to December 2018 in our hospital. They were divided into experimental group and control group by random number table method. The experimental group was given elemene combined with gefitinib, and the control group was only given gefitinib. The clinical efficacy, quality of life and immune function of the two groups were compared after 2 cycles of treatment. The PFS2 (time from slow progression of disease to rapid progression of disease) was followed up.Results:A total of 61 patients were included. There were 30 cases in the experimental group and 31 cases in the control group. The disease control rates of the experimental group and the control group were 83.3% (25/30) and 58.1% (18/31) respectively, and the difference was statistically significant ( χ2=4.680, P=0.031). The short-term efficacy of the experimental group was better than that of the control group, and the difference was statistically significant ( Z=-2.623, P=0.009). The median PFS2 of the experimental group was 4.20 months (95% CI: 3.94-4.46), and the median PFS2 of the control group was 4.00 months (95% CI: 2.94-5.07), with a statistically significant difference ( χ2=4.948, P=0.026). Quality of life was compared between the two groups: in terms of physical function, emotional function and overall quality of life, score differences before and after treatment of the experimental group were higher than those of the control group, with statistically significant differences [6.67(-6.66, 20.00) vs. 0(-6.66, 6.66), Z=-2.429, P=0.015; 29.17(2.08, 56.26) vs. 12.49(-14.59, 39.57), Z=-2.263, P=0.024; 16.67(-33.33, 56.67) vs. 8.34(-18.74, 35.42), Z=-2.249, P=0.025]. In terms of immune function, CD4 + T cells level in the experimental group increased after treatment compared with that before treatment (44.27%±6.78% vs. 41.17%±3.73%, t=-2.426, P=0.022), and CD8 + T cells level decreased compared with that before treatment (21.47%±3.18% vs. 23.50%±2.37%, t=2.532, P=0.017). After treatment, the level of CD4 + T cells in the experimental group was significantly higher than that in the control group (44.27%±6.78% vs. 39.63%±5.80%, t=2.725, P=0.011). Conclusion:β-elemene combined with gefitinib has a certain effect in the treatment of advanced lung adenocarcinoma patients with slow progression after first-line gefitinib treatment, and the quality of life and immune function are improved. It is worthy of further clinical research.
ABSTRACT
Objective To investigate the protective effect and underlying mechanism of the superoxide dismutase mimic, manganese (Ⅲ) tetrakis (1-methyl-4-pyridyl) porphyrin pentachloride (MnTMPyP), on paraquat (PQ) -induced lung epithelial-like cell injury. Methods Alveolar epithelial-like cells (A549) were pretreated with 10 μmol/L of MnTMPyP for 1.5 h and then cultured with or without PQ (750 μmol/L) for 24 h. Cell survival was determined using the MTT assay. Reactive oxygen species (ROS) production and Ca2+ levels were measured using flow cytometry. Glutathione reductase (GR) activity was determined using spectrophotometry. Expressions of the endoplasmic reticulum (ER) stress proteins, glucose regulatory protein 78 (Grp78) and C/EBP homologous protein (CHOP), were measured using Western blotting. Results Cell viability and GR activity were decreased, but ROS production, cytoplasmic Ca2+ levels, and expressions of Grp78 and CHOP were all increased in the PQ group compared to those in the control group. There were no statistically significant changes in the MnTMPyP group. Cell viability and GR activity were increased, while ROS production, cytoplasmic Ca2+ levels, and expressions of Grp78 and CHOP were all significantly reduced in the MnTMPyP group compared to those in the PQ group. Conclusion MnTMPyP effectively reduced PQ-induced lung epithelial-like cell injury, and the underlying mechanism is related to antagonism of PQ-induced ER stress and oxidative stress.
ABSTRACT
Objective To investigate relationship of platelet (PLT) count with clinicopathological features and prognosis of patients with breast cancer,and explore the susceptibility index to evaluate prognosis of patients with breast cancer.Methods A retrospective analysis of clinical data of 498 patients with breast cancer in January 1995 to December 2005 was carried out.PLT count was tested.Those patients were divided into group A (PLT ＜ 150 × 109/L),group B[(150-250) × 109/L],and group C (PLT ＞ 250 × 109/L) according to PLT count level.The relationship of platelet count with clinicopathological features was analyzed.Kaplan-Meier and Cox proportional hazards model were used for univariate analysis and multivariate analysis of PLT impact on survival time.Results There was positively correlated between PLT count and clinicopathological features (Pearson coefficient ＞ 0,P ＜ 0.05).There was negative correlated between PLT count and survival time (Pearson coefficient =-O.583,P ＜ 0.05).The survival time of groups A,B and C were significantly different (P =0.018).Cox proportional hazards model multi-factor analysis showed that PLT count was an independent factors affecting survival time (OR =2.256,P ＜ 0.05).Conclusions Patients with breast cancer associated with increased emphasis and PLT count.PLT count had negative correlation with survival time.PLT count could be a susceptible index to predict the prognosis of patients with breast cancer.
ABSTRACT
Objective To investigate the apoptosis mechanism induced by paraquat (PQ) in human type Ⅱ alveolar epithelial-like A549 cells.Methods A549 cells were cultured in vitro.The cells in the experimental group were exposed to various concentrations of PQ (50,100,150,and 200 μmol/L),while those in the control group were cultured in RPMI1640 medium.After treatment for 24 and 48 h,the cell survival rate was assessed by MTT assay.Morphological changes in the nuclei were observed by Hoechst 33258 fluorescence staining.Cellular apoptosis and mitochondrial transmembrane potential were assayed by flow cytometry.The activities of caspase-3 and caspase-9 were assayed by spectrophotometry.Western blotting was used to analyze the expression of proteins in the Bcl-2 family,such as Bcl-2,Bcl-xL,Bax,and Bak.Results PQ exhibited significant anti-proliferative activity in A549 cells.PQ-treated A549 cells were subjected to Hoechst 33258 staining.The hallmarks of apoptosis were detected,and the degree of apoptosis increased.Mitochondrial membrane potential was decreased,the levels of active caspase-3 and caspase-9 increased,the expression of Bcl-2 and Bcl-xL was decreased,and the expression of Bax and Bak was increased.These effects occurred in concentration-and time-dependent manners.Conclusion PQ efficiently induced intracellular apoptosis through the mitochondrial pathway in A549 cells.

ABSTRACT
Blood Replenishing Angelica Decoction [Danggui Buxue Tang (DGBXT)]is a wellknown TCM prescription composed of Radix Angelicae Sinensis and Radix Astragali with the actions ofinvigorating "Qi" and enriching blood. Its action to curtail endothelial permeability induced by histaminewas studied. Endothelial cells isolated from the aorta of neonatal calf were cultured on polycarbonate mi-croporus filter membrane to develop a confluent endothelial monolayer. After purfused with either plainHank's balanced salt solution or that containing 5 g/L albumin, the monolayer was treated with 10-4 mol/L histamine for 30 min either with or without preincubation for 60 min with 10-4 g/mL of DGBXT. Fluidfiltration coefficient (Kf), filtration volume (Jv) and osmotic reflective coefficient (σ) of protein were thenmeasured. The findings showed that DGBXT could curtail the lowering of Kf and Jv and elevation of σ in-duced by histamine, indicating that DGBXT could inhibit the action of histamine on endothelial permeabili-ty, but its mechanism of action needs further study.
ABSTRACT
Epicatechin content in Uncaria macrophylla Wall. was determined by RP-HPLC. As aresult, the epicatechin contents were 0.38％ in the hook and stem, and 0. 820％ in the leaf. Thus it seemedto be more worthwhile to produce epicatechin from the leaf rather than from the hook and stem.
