Objective: This work aimed to investigate the negative prognostic factors of bronchioloalveolar carcinoma (BAC) and adenocarcinoma with BAC characteristics, based on the 2004 pathological classification by the World Health Organization (WHO), which were further verified with the new pathological classification of lung adenocarcinoma (WHO 2011), to identify crucial factors that determine the prognosis of BAC and adenocarcinoma with BAC features, and to prove the coherence of the two pathological classi-fications in assessing clinical prognosis. Methods: Upon pathological diagnosis, some of the 193 cases of BAC or adenocarcinoma with BAC features were categorized into adenocarcinoma in situ (AIS) or minimally invasive adenocarcinoma (MIA), based on the 2011 WHO classification. Gender, age, tumor size, familial cancer history, smoking history, TNM stage, symptoms, duration of symp-toms, and the choice of treatment were recorded and analyzed for prognosis. The survival rate was calculated by Kaplan-Meier method. Log-rank test was introduced to compare the survival rate. Univariate and multivariate factors for the survival rate were analyzed by Cox proportional hazards regression model. Results:The overall 1-, 3-and 5-year survival rates were 84.3%, 60.6%, and 45.6%, respec-tively. Cox univariate analysis revealed that the tumor size, symptoms, TNM stage, pathological outcomes, and the choice of treatment were all prognostic factors. Cox multivariate analysis revealed that TNM stage was an independent prognostic factor for patients with BAC. Data from patients with AIS and MIA revealed better survival. Conclusion:The overall survival rate of BAC and adenocarcino-ma with BAC features are superior to that of other non-small cell lung cancer (NSCLC). The clinical symptoms are non-specific com-pared with other types of NSCLC. Clinical stage at diagnosis is a key prognostic factor, such that early correct diagnosis significantly improves survival. The new classification criteria of WHO, released in 2011, is more elaborate and more conducive to clinical practice.

Objective To study the effect of modified Xiaochaihu Decoction on NF-kB and HSP70 of BRL cell induced by cisplatin. Methods BRL Cells were divided into control group, cisplatin group, high and low dose of modified Xiaochaihu decoction. Complete cell protein dot blot technique and immunohistochemisth analysis were appllied to detect the change of NF-kB and HSP70. Results There was a significant increase in NF-kB and decrease in HSP70 of BRL cell induced by cisplatin compared with control group. There was a significant decrease of NF-kB in modified Xiaochaihu decoction group compared with cisplatin group. There were increases of the expression of HSP70 in both high and low dose group, but only the high dose group demonstrated significant difference. Conclution The expression of NF-kB of BRL cell induced by cisplatin can be inhibited while the expression of HSP70 can be enhenced by modified Xiaochaihu decoction. It may be one of important mechanisms of relieving cell oxidize lesion and inhibiting apoptosis by modified Xiaochaihu decoction.

Objective To compare the effects of dexmedetomidine and fentanyl on the median effective concentration (EC50) of propofol required for inducing respiratory depression.Methods ASA physical status Ⅰ or Ⅱ patients,aged 30-50 yr,weighing 50-75 kg,with body mass index of 22-28 kg/m2,scheduled for elective gynecological surgery under general anesthesia,were randomly divided into 3 groups:control group (group C),dexmedetomidine group (group D) and fentanyl group (group F).Dexmedetomidine 0.5 μg/kg and fentanyl 1.5 μg/kg in 10ml of normal saline were infused over 10 min in D and F groups,respectively,while the equal volume of normal saline was given in group C.Lidocaine was injected intravenously followed by target-controlled infusion of propofol.In C,D and F groups,the initial target concentration of propofol was 2.5,2.1 and 1.1 μg/ml,respectively,and the ratio between the two successive concentration gradients was 1.1.It was defined as positive when patients developed respiration depression.EC50 and 95％ confidence interval of propofol inducing respiratory depression were calculated.BIS values and OAA/S scores were recorded after admission to operating room (T0),after infusion of dexmedetomidine,fentanyl or normal saline,at 5 and 10 min after the start of propofol target-controlled infusion and after the target effect-site and plasma concentrations were balanced.Results EC50 (95％ confidence interval) of propofol required for inducing respiratory depression was 2.72 (2.55-2.91),2.15 (2.05-2.27)and 1.17(1.08-1.25) μg/ml in C,D and F groups,respectively.Compared with group C,the EC50 was significantly decreased in D and F groups and the BIS values and OAA/S scores were increased in group F (P ＜ 0.05),and no significant changes were found in the BIS values and OAA/S scores in group D (P ＞ 0.05).The EC50 was significantly decreased and the BIS values and OAA/S scores was increased in group F as compared with group D (P ＜ 0.05).When the BIS values reached 65 or OAA/S scores was 3,the effect-site concentration was significantly lower in D and F groups than in group C (P ＜ 0.05).In C,D and F groups,the percentage of patients who developed upper airway obstruction caused by glossocoma was 100％,60％ and 20％,respectively,and who developed decreased respiratory rate or apnea (RR≤ 8 bpm or respiratory arrest time≥ 15 s) was 0,40％ and 80％,respectively.Conclusion Although dexmedetomidine induces no respiratory depression,dexmedetomidine can enhance the potency of propofol required for inducing respiratory depression and the prtency is lower than that of small-dose fentanyl.

OBJECTIVETo investigate the ability of invasion and migration of breast cancer MDA-MB-231 cells under serum starvation and hypoxia, and the effect of antiangiogenic drugs, rh-endostatin and bevacizumab, on the ability of invasion and migration of breast cancer cells under serum starvation and/or hypoxia, in order to explore the potential risk of antiangiogenic therapy in clinics.

METHODSThe cells were randomized into 4 groups, i.e., group A: 10% fetal bovine serum (FBS) group; group B: hypoxia + 10% FBS group; group C: serum starvation group; group D: hypoxia + serum starvation group; each group was further divided into three subgroups as blank control, treated with rh-endostatin and bevacizumab, respectively. Cell counting kit-8 (CCK-8) was used to assess the inhibition rate of cell growth induced by endostatin and bevacizumab, in order to determine the proper working concentration and time of the two drugs. Transwell assay was conducted to detect the cell invasion and migration in vitro. The expressions of c-Met and MMP-9 were detected by Western blot. The cells treated with rh-endostatin or bevacizumab under serum starvation were tested by hybridization using Exiqon miBase 18.0 microarray. The miRNAs which exibited significant differences (P < 0.05) in miRNA hybridization were verified by real-time PCR assay.

RESULTSCCK-8 assay showed that the inhibition rates of MDA-MB-231 cells cultured with 800 mg/L rh-endostatin for 48 h and 24 h were (32.2 ± 2.5)% and (27.0 ± 1.3)%, respectively, showing a significant difference (P = 0.023). The inhibition rates of MDA-MB-231 cells cultured with 80 mg/L bevacizumab for 48 h and 24 h were (30.5 ± 1.4) % and (26.1 ± 2.4) %, respectively, showing also a significant difference (P = 0.015). The Transwell assay showed that in the starvation blank group, the number of invaded and penetrated cells were 28.8 ± 2.2 and 31.4 ± 1.5, respectively, significantly different from that in the rh-endostatin and bevacizumab groups (P < 0.05). The relative expressions of c-Met and MMP-9 were 0.213 ± 0.017 and 0.542 ± 0.048, respectively, with a significant difference from those of the groups treated with each drug (P < 0.05 for both). The numbers of penetrated cells in the Transwell assay treated with rh-endostatin in hypoxia were 17.5 ± 2.1 and 16.5 ± 2.8, respectively, and the numbers of penetrated cells in the Transwell assay treated with bevacizumab were 16.3 ± 3.5 and 17.5 ± 2.4, respectively, showing no significant difference among them (P > 0.05 for both). The ability of migration and invasion of MDA-MB-231 cells and the expression of c-Met and MMP-9 were not impacted by hypoxia (P > 0.05). Real-time PCR assay showed that only the levels of miR-2355 and miR375 were significantly and stably decreased in the cells which had increased ability of invasion and migration. The relative expression levels of miR375 and miR-2355 in the serum starvation blank group were 0.550 ± 0.036 and 0.852 ± 0.121, respectively, significantly lower than that in the groups treated with rh-endostatin or bevacizumab (P<0.05). In the serum starvation group, the expression levels of miR375 and miR-2355 of cells treated with rh-endostatin were 0.295 ± 0.012 and 0.253 ± 0.011, and the expression levels of cells treated with bevacizumab were 0.234 ± 0.020 and 0.309 ± 0.022, respectively, (P > 0.05 for all). Compared with the serum starvation blank group, the expression levels of miR2355 and miR375 were significantly decreased when cells were treated with rh-endostatin/bevacizumab under serum starvation, but no significant difference was found between the two drugs (P > 0.05). However, hypoxia did not affect the expressions of miR2355 and miR375 (P > 0.05).

CONCLUSIONSThe results of this study suggest that serum starvation can increase the ability of invasion and migration of breast cancer cells. Furthermore, both rh-endostatin and bevacizumab may enhance their invasion and penetration ability under serum starvation condition.

Objective To explore the role of hypoxia inducible factor 1α(HIF-1α)-mediated signaling pathway in angiotensin Ⅱ(Ang Ⅱ)induced renal interstitial fibrosis. Methods Renal tubular epithelial cells were cultured and treated with different concentrations (10-9-10-6 mol/L)of Ang Ⅱ for 24 h and 48 h.Real-time quantitative PCR and Western blotting were preformed to detect the mRNA and protein expressions of HIF-1α,prolyl hydroxylase 2 (PHD2)and tissue inhibitor of metalloproteinase 1 (TIMP-1)in renal tubular epithelial cells. Results HIF-1αmRNA level was increased with Ang Ⅱ treatment in a concentration dependent manner.When cells were treated with Ang Ⅱ concentration at 10-7mol/L for 24 h,the mRNA level was markedly increased by 166%.Furthermore,by real-time quantitative PCR and Western blotting,compared with the control group,Ang Ⅱincreased the mRNA and protein levels of HIF-1α and TIMP-1 (P<0.05,respectively),while the mRNA and protein levels of PHD2 were decreased markedly (P<0.05,respectively)in renal tubular epithelial cells.Conclusion Ang Ⅱ reduces HIF-1αdegradation in renal tubular epithelial cells probably by reducing the expression of PHD2,which increases the expressions of HIF-1α and TIMP-1 involved in renal interstitial fibrosis.

ObjectiveTo investigate the effect of recombinant human growth hormone (rhGH) on JAK2-STAT3 signaling pathway and on the growth of human colon cancer cells at different growth hormone receptor (GHR) expression status.MethodsLOVO and HCT-8 cell lines were selected after the colon cancer cells were screened using flow cytometry according to the GHR expression status.The growth of human colon cancer cells after intervention with rhGH was detected by MTT assay.The proliferation index ( PI),cell cycle,and apoptosis were detected by flow cytometry.The expression of JAK2-STAT3 signaling pathway proteins was detected by Western blot.ResultsHCT-8 cell line showed positive GHR expression (59.6％),and LOVO cell showed negative GHR expression (3.5％).The growth rate of HCT-8 cells increased after rhGH treatment.Compared with the untreated HCT-8 cells,the rhGH-treated HCT-8 cells showed reduced apoptosis,elevated PI,and increased G2/Mphase cells ( P =0.0073).Western blot revealed that rhGH up-regulated the proteins of pJAK2,pSTAT3,VEGF,Cyclin D1,and Bcl-xL in HCT-8 cells.In contrast,no such changes were observed in LOVO cells treated with rhGH.ConclusionsrhGH may promote the growth of HCT-8,the cell line of high GHR expression,and up-regulate the expression of a number of key nodes in JAK2-STAT3 signaling pathway.However,rhGH may not affect LOVO,the cell line of low GHR expression.

Objective To study the expression of SGK1 in T lymphocytes from pediatric asthma,and the effect of SGK1 on the differentiation of T cells,also to explore the function of SGK1 regulating the differen-tiation of T subset in pediatric asthma. Methods Twenty-eight children with asthma were recruited in Xi′an children′s hospital and divided into moderate group and severe group according to diagnostic guideline of asth-ma. The serum levels of IL-4,IL-13 and IL-17A were analyzed by ELISA. The CD4 +T cells from PBMC and na?ve T cells were selected using magnetic beads. Na?ve T cells were differentiated in vitro under cytokines. SGK1 expression were analyzed with Real-time PCR. The ability of Th2 and Th17 on secreting IL-4 and IL-17A were detected after SGK1 was inhibited by siRNA. In vivo,shRNA-SGK1 Na?ve T cells were transferred into the mice asthma models by intravenous injection. The airway inflammation were observed in shRNA-SGK1 Na?ve T models. Results Compared with healthy children,the serum levels of IL-4、IL-13 and IL-17A increased signifi-cantly in the children with asthma. Importantly,the levels of these three cytokines were much higher with the de-velopment of asthma. SGK1 were up-regulated remarkably in CD4 +T cells from the children with asthma and were positively correlated with IL-13 and IL-17A. Besides,SGK1 expression increased in the differentiated Th2 and Th17 in vitro,but had no change in the differentiated Th1. The levels of IL-4 and IL-17A associated with Th2 and Th17 decreased after SGK1 was inhibited by siRNA. Similarly,In vivo,the serum levels of IL-13 and IL-17A and airway inflammation were reduced in shRNA-SGK1 Na?ve T models. Conclusion The over-expres-sion of SGK1 in pediatric asthma enhances the asthma progress by promoting the differentiation of T subsets.
