Objective:To investigate the clinicopathological characteristics of lung cancer patients with axillary lymph node metastasis (ALNM). Methods:The clinical data of 91 lung cancer patients with ALNM who were treated in Zhejiang Cancer Hospital from January 1st, 2007 to December 31st, 2013 were retrospectively analyzed. The relevance of the sites of the tumor site, local lymph node, and ax-illary lymph node was checked by contingency table. Survival rates were calculated by the Kaplan-Meier method and compared by a log-rank test. Cox proportional hazards model was applied to analyze the prognostic factors. Results:The proportion of lung cancer pa-tients with ALNM was 0.63%, and the patients were often presented with adenocarcinoma, peripheral tumor type, pleura invasion with pleural effusion, or chest wall invasion. A relationship between tumor sites, local lymph node sites, and axillary lymph node sites was observed. The median survival time of lung cancer patients with ALNM was 19.02 months, and the two-year survival rate is 62.64%. Patients identified with ALNM at the initial diagnosis reported poor prognosis (P=0.002). Cox regression analysis showed that the relative risk of death in patients with ALNM at initial diagnosis was elevated 2.18 times (95%CI:1.330?3.572, P=0.003). Conclu-sion:ALNM in lung cancer is rare, and it may involve through direct chest wall invasion and spread from supraclavicular and mediasti-nal lymph node metastasis or systemic origin. Patients detected with ALNM at the initial diagnosis indicated poor prognosis.

In order to explore the dose-response patterns of Gancao (Radix Glycyrrhizae) in Shanghan Lun (Treatise on Febrile Diseases), all prescriptions containing Gancao in Shanghan Lun were analyzed by frequency and hierarchical clustering analysis. The doses of Gancao used in Shanghan Lun ranged from six zhu (Chinese unit, and one zhu is equal to 0.65 g) to four liang (Chinese unit, and one liang is equal to 15.625 g). Doses of one, two, three or four liang were commonly used. One liang Gancao as juvantia was usually matched with Mahuang (Herba Ephedrae), Xingren (Semen Armeniacae) and Guizhi (Ramulus Cinnamomi) for restricting the excessive diaphoresis of Mahuang. Two liang Gancao was often matched with some couple drugs, such as Guizhi and Shaoyao (Radix Paeoniae), Shigao (Gypsum Fibrosum) and Zhimu (Rhizoma Anemarrhenae), Fuzi (Radix Aconiti Lateralis) and Ganjiang (Rhizoma Zingiberis), for warming yang to supplement qi, nourishing yin, detoxifying Fuzi, and preventing qi impairment from heat evil. Three liang Gancao was mainly matched with Banxia (Rhizoma Pinelliae) or Renshen (Radix Ginseng) for treating middle energizer emesis. Four liang Gancao was matched with Ganjiang or tonifying herbs for invigorating vital qi and relieving spasm in deficiency syndromes with contraction, palpitation or diarrhea. Gancao is used for treating many syndromes in Shanghan Lun. It is frequently used to treat excess or heat syndromes with one or two liang in a dose and deficiency or cold syndromes with three or four liang in a dose.

Background Posterior capsular opacification (PCO) is a primary complication after extracapsular cataract extraction.The mechanism of PCO is associated with proliferation,migration and epithelialmesenchymal transition (EMT) of human lens epithelial cells (LECs).To explore the target treatment of PCO is very important.Objective This study was to investigate the biological effects of second mitochondria-derived activator of caspases (Smac) on the proliferation and apoptosis of LECs.Methods Human LECs line (HLE-B3) and Smac-overexpressed LECs line were cultured,and the cells were transfected using small interfering RNA (siRNA)-Smac3 plasmid with green fluorescent protein (GFP) for 24 hours.Different concentration of transforming growth factor-β2 (TGF-β2) (5,10,20 and 50 μg/ml) or 200 μmol/L H2O2 were added respectively into the culture medium to establish PCO model and oxidative stress model.Cell counting kit-8 (CCK-8) assay was used to compare the cell proliferative activity among PBS group,TGF-β2 group and Smac-hyperexpression +TGF-β2 group.Flow cytometry was used to evaluate the apoptotic rate of the PBS group,H2 O2 group and siRNA-Smac+H2 O2 group.The expressions of Smac,caspase-3 and proliferating cell nuclear antigen (PCNA) mRNA and their proteins in the cells were detected by real-time quantitative PCR (RT-PCR) and Western blot.Results The GFP+ cells were≥ 80% 12 hours after siRNA-Smac3 transfection,with the optimal plasmid of siRNA-Smac3.GFP+ cell rate was (72.32 ± 2.31)% in the siRNA-Smac3 transfection group,which was significantly higher than that in the blank plasmid group ([4.91 ±0.24] %) (t=116.342,P<0.001).The relevant expression levels of Smac was 35.21 ±4.11 in the Smachyperexpression group,and that in the blank plasmid group was 15.24±2.48,with a significant difference between them (t =215.47,P<0.05).The cell viability of 20 ng/ml TGF-β2 affected PBS group,TGF-β2 group and Smachyperepression+TGF-β2 group was (98.4 ± 1.7) %,(98.9 ± 0.1) % and (64.2 ± 3.1) %,and the cell viability of Smac-hyperepression+TGF-β2 group was significantly lower in the Smac-hyperepression+TGF-β2 group than that in the TGF-β2 group (P<0.05).The apoptotic rate in the PBS group,H2 O2 group and siRNA-Smac+H2 O2 group were (2.9 ± 1.2) %,(45.1 ±4.5) % and (27.5 ± 1.8) %,and the apoptotic rate was evidently lower in the siRNA-Smac +H2O2 group than that in the H2O2 group (P<0.05).RT-PCR results showed that the expression levels of caspase-3 mRNA in PBS group,H2 O2 group and siRNA-Smac + H2 O2 group were 0.321 ± 0.103,0.715 ± 0.112 and 0.479 ±0.209,respectively.Compared with the H2 O2 group,the relative expression level of caspase-3 mRNA in siRNA-Smac+ H2O2 group was significantly decreased,the difference was statistically significant (P< 0.05).The PCNA mRNA expression levels in PBS group,TGF-β2 group and Smac-hyperepression+TGF-β2 group were 0.299±0.013,0.645± 0.102 and 0.490±0.209,respectively.Western blot results showed that the relative expression of caspase-3 protein in siRNA-Smac+H2O2 group and H2O2 group was 0.712±0.012 and 0.973±0.051,with significant difference between the two groups (t =132.52,P<0.05).The relative expression of PCNA protein in Smac-hyperepression+TGF-β2 group was 0.782±0.212,which was lower than 1.126±0.251 in the TGF-β2 group (P<0.05).Conclusions Smac may prevent and treat PCO by inhibiting the proliferation and promoting apoptosis of human LECs.

Objective To evaluate the effect of transitional care on the quality of life in patients with maintenance hemodialysis (MHD).Methods 101 MHD patients with symptoms of kidney < 80 points were assigned into the interventional group (47 of 51 cases completed the study) and the control group (45 of 50 cases completed the study) by random number table method.The patients in the interventional group received transitional care for 6 months,while control group received routine care.The effects on function index,satisfaction index and clinical index were evaluated at the 3rd month and 6th month after intervention.Results 6 months after intervention,the scores of physical composite,mental composite,burden of kidney disease,symptoms/problems list,effects of kidney disease in the interventional group were 51.78±5.91,55.32±5.36,29.79±17.64,79.39±6.73,68.02±11.38,while the scores of the control group were 38.22±9.46,42.03±8.32,19.58±17.25,69.49±10.10,52.09±16.78,and the difference between the two groups was statistically significant (t=5.308-9.063,Z=-3.07,P < 0.01).The scores of self-management behavior,health locus of control in the interventional group were 71.30-±5.42,25.74±2.42,while the scores of the control group were 65.0±8.74,22.47±3.97 (t=4.132,4.759,P < 0.01).The nursing satisfaction in the interventional group scored 91.06±7.29,which was significantly higher than the control group scored 86.22±10.72 (Z=-2.45,P< 0.05).The level of serum phosphorus (PO4),Ca × PO4 products,parathormone (PTH) in the interventional group were (1.76±0.35) mmol/L,(51.02±10.04) mg2/dl2,464.56 ng/L,which were significanlty lower than (2.01±0.54) mmol/L,(57.41±17.38) mg2/dl2,625.78 ng/L in the control group (t=-2.691,-2.167,-2.000 in tum,P < 0.01 or 0.05).Conclusions Transitional care achieves good effectiveness on the quality of life in patients with MHD.
