Objective To study the correlation between prognosis of non-small cell lung cancer ( NSCLC) patient and serum levels of HGF and IL-6. Methods Eligible 109 NSCLC patients and preoperative blood samples of each patient in our hospital from March 2013 to May 2014 were collected. Then the levels of HGF and IL-6 of serum samples were detected by using ELISA kit. All patients were followed up for 1 year. The neoplasm staging:67 cases were stagingⅠ-Ⅱ,38 cases were stagingⅢ,2 cases were staging IV. There were 79 cases with ad-enomatous carcinoma( ADC) ,26 cases with squamous carcinoma( SCC) and 4 cases with NSCLC. According to the TNM staging,there were 79 cases in pN( -) group,31 in pN( +) group,77 in pT(T1-T2) group and 28 in pT(T3-T4) group. Results The average concentration of HGF and IL-6 in serum were 860 pg/mL and 2. 7 pg/mL respectively. Analysis of survival indicated that,compared to those patient with lower serum level of HGF and IL-6,the survival rate of patient with high serum level was much lower. The difference was statistically signifi-cant (HGF,P=0. 019;IL-6,P=0. 002). The analysis of the patients with stageⅢdisease separately also indicated that survival rate of pa-tient with lower serum of HGF and IL-6 was higher than others. Conclusion The serum levels of HGF and IL-6 might be a effective indica-tors for predicting prognosis of the NSCLC paitents.

AIM: To investigate whether Programmed death-1 (PD-1) expression on peripheral CD4~+CD25~(nt/hi)CD127~(lo) regulatory T cells (Treg) was associated with disease progression in HIV-1-infected patients. METHODS: Peripheral blood from 108 HIV-1-infected patients in distinct disease progression statuses and 27 healthy individuals were collected in the present investigation. PBMCs were isolated by centrifugation on Ficoll-Hypaque, followed by staining with anti-CD4-PerCP, anti-CD25-FITC, anti-CD127-PE and anti-PD-1-APC. PD-1 expression on Treg was analyzed by four-color staining flow cytometry. CD4~+T cell absolute counts were determined using Multitest CD3/CD4/CD8/CD45 kit and plasma viral loads were detected on NucliSens EasyQ. All data were analyzed using SPSS14.0 software. RESULTS: In peripheral blood of healthy individuals, Treg expressed PD-1 at very low levels (1.72%±0.65%). In contrast, Treg from HIV-1-infected patients showed a significantly increased PD-1 expression (5.33%±2.24%, P<0.01). Moreover, AIDS patients exhibited statistically higher PD-1 expression on Treg (7.87%±2.23%) than newly HIV-1 infected patients (3.22%±1.01%, P<0.05) and patients in progression to AIDS(5.21%±1.72%, P<0.05). PD-1 up-regulation on Treg was closely correlated with reduced CD4~+T cell absolute counts but elevated plasma viral load. CONCLUSION: Overall, we found that PD-1 expression on peripheral Treg was up-regulated and correlated with disease progression in HIV-1-infected patients for the first time. These findings not only extend our understanding of how Treg functions in HIV-1-infected patients but also support the notion that blocking PD-1/PD-L1 interactions may represent a potential therapeutic strategy for HIV-1-infected patients.

Objective To analyze the inappropriate use of oral drugs in elderly patients admitted in internal medicine, and to guide clinical rational drugs use in elderly patients. Methods One hundred inpatients′ data over 65 years were collected in the department of geriatrics. The potentially inappropriate use of oral drug were analyzed according to the Beers criteria published in 2012 and drugs instructions. Results In 100 patients, (5.81 ± 2.78) kinds of oral drugs had been taken per inpatient. One patient was involved out-of-label usage. There were potentially inappropriate uses of oral drugs in 21 patients. Inappropriate use of oral drugs in three patients were not related to diagnosis or disease, and in 4 patients were related to morbid state, 14 patients used drugs that need to be used with caution in older adults. Conclusions There are off-label uses and potentially inappropriate medications in clinical practice, so clinical doctors should examine and assess the uses of drugs. Clinical doctors should strengthen the understanding and application of the comprehensive geriatric assessment.

Aim To establish ICR animal model with C6 glioma stem cells, to provide the ideal model for the further study of gli-oma stem cells in brain glioma model. Methods C6 glioma stem cell was cultured in vitro by suspension,and was identified with Nestin antibody. C6 stem cells of ICR mouse glioma model were used to investigate survival state and tumor volume in mice after the operation. HE staining and CD133 immunohistochemi-cal study were adopted to investigate the postoperative pathologi-cal changes in mice. Results The expression of Nestin was 96. 01% in C6 glioma stem cells, and Nestin was highly ex-pressed in the cultured C6 glioma stem cells. Mice were inocula-ted with tumor after loss of appetite, weight, behavior and slow, sluggish reaction. Tumor volume at day 21 after modeling was (9. 77 ± 6. 58) mm3 . After HE staining, the model showed the invasive growth, tumor cell shrinkage and derangement. Immu-nohistochemical CD133 staining revealed that tumor cytoplasm color was brown. Conclusion Glioma model can be established based on glioma stem cells into a high rate of tumor, the tumor cycle is short, which can be used as an ideal model for glioma.

Objective To investigate the value of measurement of cardiac output in children by bio-reactance versus echocardiography.Methods Pediatric patients admitted in pediatric department of Peking University First Hospital from September to December 2012 who needed hemodynamic monitoring were enrolled prospectively.Cardiac index(CI)and stroke volume(SV)were measured by echocardiography and non-invasive cardiac output measurement(NICOM)and compared by Spearman correlation and Bland-Alt-man analysis.Results Thirty patients were included.The median age was 7.25 years.CI[M(P5 ,P95 )] measured by NICOM and echocardiography were correlated significantly[3.42(2.28,4.92)L /(min?m2 ) vs.3.51 (2.94,4.85 )L/(min?m2 ),R =0.385,P =0.035 ].Bland-Altman analysis revealed a bias of-0.22 L/(min?m2 )(P =0.051 ),limits of agreement of -1.40 to 0.95 L/(min?m2 ).SV[M(P5 ,P95 )] measured by NICOM and echocardiography were correlated more significantly [36.3 (12.6,87.8 )ml vs.39.4(14.7,86.9)ml,R =0.768,P ﹤0.001 ].Bland-Altman analysis revealed a bias of -3.1 ml(P =0.176),limits of agreement of -27.4 to 21.2 ml.Conclusion There is no significant difference between NICOM and echocardiography for the measurement of CI and SV in pediatric patients.Further validation studies need to be conducted before routine clinical use.

The variation of blood glucose in 1 147 patients with type 2 diabetes mellitus was monitored by continuous glucose monitoring system(CGMS). The results showed that the peak hours of nocturnal hypoglycemia occurred during 22 : 00-2 : 00. The incidence of nocturnal hypoglycemia was negatively correlated with mean blood glucose and blood glucose at three hours after supper. The probability of hypoglycemia was up to 50% when blood glucose level had been as low as 4. 7 mmol/L at 3 h after supper.

Objective To observe the levels of HIF-α and TGF-β in the liver tissue,change of serum transaminase in different phases after paraquat (PQ) toxicity and liver histopathology change in PQinduced liver toxicity of rats models in order to analyze the relationship between HIF-1 α and hepatic toxicity induced by PQ.Methods A total of 48 healthy SD rats were randomly (random number) assigned into 2 groups:PQ poisoning group (n =42,20％ PQ solution,50 mg/kg in 1mL) and control group (n =6,normal saline 1mL).Rats were separately sacrificed and liver tissue samples were harvested at 2,6,12,24,48,72 h and 120 h after PQ administered by gastric lavage.Arterial blood gas (ABG) analysis and serum alanine transaminase were assayed.Liver tissue HE and Masson staining and immunochemistry changes were also investigated.HIF-1α and TGF-β levels were detected by Western blot technique.Results Lactic acid level was significantly higher in PQ group than that in control group at 6 h after PQ exposure (P ＜ 0.05).The level of serum alanine transaminase was increased and significantly higher if PQ group than that in control group at 2 h after PQ poisoning (P ＜ 0.05).The level of HIF-1 α and TGF-β protein in the liver tissue were up-regulated significantly and higher in PQ group than those in control group at 2 h after PQ exposure (P ＜ 0.05).The hepatocytes necrosis and inflammatory cells infiltration were observed around portal area 2 h after PQ poisoning.At 12 h after PQ exposure,the periportal area filled with necrosis of hepatocytes and the necrosis began to extend,and huge amounts of inflammatory cell infiltration were found.Cord-like fibroplasia was found.All the histological changes were around central portal area and were enlarged gradually.Conclusions The results show that there are increased level of HIF-1 α in the early stage of PQ poisoning rats.The liver fibroplasia may be associated with increasing the level of TGF-β promoted by HIF-1α.
