ObjectiveTo investigate the expression of urotensin Ⅱ(UⅡ) in the lung cancer tissue from surgical resection of lung cancer patients,and to detect the relationship between UⅡ expression and pathologie types and the clinical stages of lung cancer.MethodsThe expression rates of UⅡof 45 lung cancer tissues and 20 inflammatory pseudotumor were measured by immunohistochemical assay,and the relationship between UⅡ expression and the pathologic types and clinical stages of lung cancer was analyzed.ResultsUⅡwas mainly distributed in lung cancer cell cytoplasm,which was tan-yellow particles.The positive expression rate of UⅡin nonsmall cell lung cancer was 61.3％ (19/31),which was higher than that in small cell lung cancer(7.1％,1/14)and pulmonary inflammatory pseudotumor( 15.0％,3/20) (P ＜ 0.01 ).The positive expression rate of UⅡ was 100％ in adenocareinoma.The positive expression rate of UⅡin staging Ⅲ non-small cell lung cancer( 85.7％ )was higher than that of staging Ⅰ ( 16.7％ ) ( P ＜ 0.05).ConclusionUⅡ cxists in the cytoplasm of lung cancer cells,and the expression of UⅡis correlated with the pathological type and TNM staging of lung cancer.

Objective:To investigate the expression level of pyruvate kinase M2 (PKM2) in tissues of non-small cell lung cancer (NSCLC) patients and the correlation between PKM2 expression level and radiation sensitivity. Methods:A total of 45 NSCLC pa-tients were chosen and treated with radiotherapy for two months after surgery. The patients were classified into four groups based on the curative effect. The mRNA expression levels of PKM2 in tumor and the homologous paraneoplastic tissues of NSCLC patients were de-tected prior to radiotherapy using real time-polymerase chain reaction (RT-PCR), and the protein expressions of PKM2 in the tumor and paraneoplastic tissues of NSCLC patients were detected with Western blot analysis and immunohistochemical method. The mRNA and protein expression levels of PKM2 in the tumor tissues of different groups were detected with RT-PCR and Western blot assays. Re-sults:The effective rate of radiotherapy for 2 months is 44.8%in NSCLC patients. The expression level of PKM2 is significantly high-er in tumor tissues than in homologous paraneoplastic tissues of NSCLC patients and is negatively correlated with the curative effect of radiotherapy. Conclusion:The expression level of PKM2 is significantly higher in tumor tissues than in the paraneoplastic tissues of NSCLC patients. Patients with lower PKM2 expression level are more sensitive to radiotherapy.

AIM: To investigate the inhibitory effect of L-carnitine on high glucose-induced apoptosis of human aortic endothelial cells (HAECs) and the molecular mechanisms.METHODS: The apoptosis of HAECs was induced by high-glucose incubation.HAECs were treated with L-carnitine at different concentrations (50, 100 and 200 μmol/L).The cell viability was measured by MTT assay.The cell apoptosis was assessed by Hoechst 33258 staining and flow cytometry.Colorimetric method was employed to detect the caspase-3 activity in the HAECs.The protein expression and phosphorylation levels were determined by Western blot.RESULTS: High-glucose incubation dramatically decreased the cell viability and induced apoptosis.The protein kinase R-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme-1 (IRE1) and activating transcription factor 6 (ATF6) signaling pathways of endoplasmic reticulum stress were activated to induce cell apoptosis via down-stream caspase-4/3 cascade.However, L-carnitine treatment significantly attenuated the cell apoptosis and increased the cell viability in a concentration-dependent manner.L-carnitine also significantly suppressed endoplasmic reticulum stress and ATF6 signaling in high glucose-incubated HAECs without attenuating PERK and IRE1 signaling.The expression of site-1 protease (S1P) and site-2 protease (S2P) was inhibited by L-carnitine treatment, thus decreasing pro-apoptotic factor ATF6 p50 produced by ATF6 cleavage.CONCLUSION: L-carnitine inhibits high glucose-induced apoptosis of HAECs by inhibiting ATF6 signaling.

Background and purpose:MicroRNA (miRNA) belongs to a class of 19 to 30 nucleotide-long, endogenous noncoding RNA expressed in eukaryotes and predominantly inhibits gene expression at the post-transcriptional level. The miRNAs play critical roles in cell proliferation and differentiation, apoptosis, metabolism, and immune regulation. This study aimed to detect the expression of miR-216a-5p in lung cancer tissues and lung cancer cell lines, and to discuss the effects of miR-216a-5p on the invasion ability of lung cancer cells and the mechanism.Methods:Quantitative real-time PCR (qRT-PCR) was used to detect the expression of miR-216a-5p in lung cancer tissues of 55 cases and 7 lung cancer cell lines. Three lung cancer cell lines of A549, 95D and H460 were transiently transfected by miR-216a-5p, and Transwell was used to detect the effects of miR-216a-5p on the invasion of lung cancer cell lines. The dual luciferase reporter plasmids containing the miR-216a-5p candidate target gene and the gene of matrix metalloproteinase 16 (MMP16) were predicted and constructed. qRT-PCR and Western blot were used to detect the changes in mRNA and protein levels of target geneMMP16 by miR-216a-5p. The interference of MMP16 by siRNA and up-regulation miR-216a-5p by transfection were compared on the invasion of lung cancer cells.Results:The miR-216a-5p expression levels were all signiifcantly reduced in 90.91% (50 of 55 patients) tumor tissues compared with corresponding adjacent normal lung tissues (P<0.05). The miR-216a-5p expression levels were only 7.00%-32.00%in 7 lung cancer cells compared with the control group (P<0.05). Up-regulation of the expression of miR-216a-5p inhibited the invasion of lung cancer cells; interference of MMP16 by siRNA, as well as up-regulating miR-216a-5p by transfection, inhibited the expression of MMP16 in lung cancer leading to inhibition of the invasion of lung cancer cells. Conclusion:miR-216a-5p can be a candidate marker in clinical diagnosis and it can inhibit the invasion of lung cancer cells by down-regulating the expression of MMP16.

Objective To study the effects of oral rehydration with the solution of pyruvate-glucoseelectrolyte (PGES) by comparison with the bicarbonate-glucose-electrolyte solution (BGES) on resuscitation in rats with lethal hemorrhagic shock.Methods Sixty adult male SD rats with intra-gastric tube,and cannulation of femoral artery and vein were subjected to 45％ total blood volume loss from the femoral artery,and then randomly divided into three groups (n =20 in each group):no fluid resuscitation group (NR),oral fluid resuscitation with the PGES group (PGES) and oral fluid resuscitation with the BGES group (BGES).In NR group,the animals received no fluid replacement or any other treatment.Rats in PGES and BGES groups were infused intra-gastrically with pre-warmed PGES or BGES in volume of 2 times shed blood given at 30 min after hemorrhage and completed within 6 hours.Blood samples in each group were collected from the abdominal aorta before or at 0,1,2,4 h post hemorrhage to detect serum alanine aminotransferase (ALT),creatinine (Cr),creatine phosphate kinase isoenzyme (CK-MB) and intestinal fatty acid binding protein (iFABP).Another 84 rats randomly divided into four groups:NR group (n =24),PGES group (n =24),BGES group (n =24),and no hemorrhage group (NH group,n =12).Rats in the three hemorrhage groups were treated the same as described above,and the rats in NH group underwent the same surgical procedure without hemorrhage were served as the sham group.All these rats were observed for their 24-hour survival rates.Results The 24-hour survival rates of PGES and BGES groups were both significantly higher than the rate of NR group (11/24 vs.1/24,x2 =18.087,P ＜0.01 ; 5/24 vs.1/24,x2 =6.445,P ＜ 0.05) ; the survival rate of PGES group was also significantly higher than that of BGES group (11/24 vs.5/24,x2 =4.02,P ＜ 0.05).All levels of ALT,CK-MB,Cr and iFABP in both the NR group and two oral resuscitation groups at 1 h,2 h and 4 h post hemorrhage were significantly higher than those before the blood loss,respectively (P ＜ 0.01).These biomarkers at 2 h,4 h post hemorrhage were significantly lower in the PGES and BGES groups than those in NR group (P ＜ 0.01) ; the serum levels of ALT,CK-MB,Cr and iFABP were significantly lower in the PGES group than those in the BGES group at 2 h and 4 h post hemorrhage,respectively (P ＜ 0.05).Conclusions Present results demonstrated that the pyruvate-enriched oral re-hydration solution (ORS =PGES) was more effective in preserving the organ function and prolonging the animal survival after resuscitation of lethal hemorrhagic shock in comparison with the bicarbonate-containing ORS (BGES).The oral re-hydration solution (PGES) recommended by the World Hygiene Organization (WHO ORS) may require further improvement in oral resuscitation of shock and the PGES may be recommended as a choice of oral re-hydration salts in the treatment of lethal hemorrhagic shock when intravenous administration is not available.

Aliquat 336 functionalized chelating adsorbent derived from chitosan for enrichment and separation of Y(Ⅲ) were investigated by static adsorption method. The adsorption of Y(Ⅲ) was greatly influenced by the pH of solution, and reached maximum at 20 ℃ using 90 mg/L Y(Ⅲ) at pH 4. 9, and the adsorption of Y(Ⅲ) followed a pseudo-second-order kinetics model and the Langmuir isotherm model. The reduction of Y(Ⅲ) adsorption with the increasing of temperature meant that the adsorption process was exothermic. XPS analysis demonstrated that both cations and anions of the adsorbent were involved in adsorption process, thereby resulting in an improved adsorption of Y(Ⅲ). The adsorbent was thus efficient for enrichment and separation of rare earths from waste rare earth phosphor.

Objective To evaluate the international prognostic index (IPI) in peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). Methods From May 2005 to May 2008, 75 patients of PTCL--NOS were reviewed. All the patients were diagnosed again by immunohistochemical staining. According to IPI, they were divided into four groups:low risk (0-1), intermediate-low(2), intermediate-high(3), high risk (4-5), then the difference of treatment effectiveness and prognosis among them were analysed. Results IPI scoring of 75 patients were classified as low risk , 10 (13.3%); as intermediate-low, 14 (18.7%); as intermediate-high, 28 (37.3 %); as high risk, 23 (30.7%). There was a significant difference in complete remission rates with first line treatment(X2=16.677,P=0.001), and overall survival rates (P=0.0000) among four groups. Median survival time among 4 groups were 36+, 29.00, 17.00, 10.00 months. 1-year OS were 100.00 %, 89.05 %, 64.24 %, 15.73 %; 2-year OS were: 75.00 %, 53.01%, 34.42 %, 2.00 % respectively. Multivariate analysis showed that both complete remission rates of first line treatment(P=0.002) and IPI(P = 0.049) were independent prognostic factor for PTCL-NOS, while single index of IPI was not. Conclusion At a certain extent, IPI model was able to predict response of treatment effective and prognosis in PTCL-NOS.
