Objective To investigate the combined effect and mechanism of metformin (Met) and 2-deoxy-D-glucose (2DG) on cell proliferation and apoptosis in liver cancer cells HepG2 and Hep3B.Methods Wst-1 reagent was used to determine the anti-proliferation effects after treatments with Met and 2DG alone or combined in HepG2 and Hep3B cells.Microscopy was used to observe cell morphological changes after treatments with Met and 2DG alone or combined in HepG2 and Hep3B cells.Cell apoptosis was observed by flow cytometry after treatment of different kinds of drugs.Western blotting was used to analyze the protein expressions of Caspase-3,PARP,Mcl-1 of HepG2.Results The survival rate of HepG2 cells in the combination group was (22.48 ± 0.51)％,and compared with the control group (100.00 ± 5.05)％,Met group (80.68 ±5.10)％ and 2DG group (72.56 ±4.34)％,the differences were statistically significant (P ＜ 0.001;P ＜ 0.001;P =0.001).The survival rate of Hep3B cells in the combination group was (29.16 ± 1.34) ％,and compared with the control group (100.00 ± 1.23) ％,Met group (59.58 ± 1.92) ％ and 2DG group (33.87 ± 1.95) ％,the differences were statistically significant (P ＜ 0.001;P ＜ 0.001;P =0.001).Microscopy observation showed that combined treatment of Met and 2DG caused less viable adherent cells of HepG2,but more floating dead cells.While the combination group also caused a decrease in the density of Hep3B cells,but did not significantly increase the shedding of cells.The apoptosis of HepG2 cells in the combination group was (39.63 ± 0.21) ％,and compared with the control group (7.12 ± 0.14) ％,Met group (12.56 ± 0.35) ％ and 2DG group (15.16 ± 1.93) ％,the differences were statistically significant (P ＜0.001;P ＜ 0.001;P =0.001).The apoptosis of Hep3B cells in the combination group was (12.58 ± 1.03) ％,and compared with the control group (2.82 ± 0.51) ％ and Met group (8.98 ± 0.86) ％,the differences were statistically significant (P ＜ 0.001;P =0.007),but compared with the 2DG group (12.40 ± 1.78) ％,the difference was not statistically significant (P =1.000).Furthermore,Western blotting demonstrated that the combined treatment induced evident Caspase-3 activation and poly ADP-ribose polymerase (PARP) cleavages,and decreased expression of Mcl-1.Conclusion The combination of Met and 2DG can effectively inhibit cell proliferation of HepG2 and Hep3B,and induce apoptosis of HepG2 cells.The mechanism may be involved with Caspase-3 activation,cutting PARP substrate and decreasing Mcl-1 protein.

Objective To investigate the expression of nucleotide-binding oligomerization domain protein 2 (NOD2)in serum of patients with hepatocellular carcinoma (HCC),and to analyse the roles of NOD2 in HCC development and its clinical diagnostic value.Methods This study including 66 patients with HCC in the hospi-tal from March 1,2013 to December 31,2014 and 61 healthy controls.Serum NOD2 levels were determined by enzyme-linked immunosorbent assay (ELISA).Analysis of significance was performed with rank sum test using SPSS statistical 16.0 software.Results Serum levels of NOD2 in HCC patients were 171 pg/ml,significantly higher than that of healthy controls(95 pg/ml,Z =-5.00,P =0.00),and the serum NOD2 levels were correla-ted with clinical stage of HCC (H=56.26,P =0.00).Compared with the serum NOD2 levels in stageⅠ,Ⅱpatients (106 pg/ml)and healthy controls (95 pg/ml),the serum NOD2 level in stage Ⅲ and Ⅳ (220 pg/ml) were significantly increased (χ2 =31.24,P =0.00;χ2 =47.23,P =0.00),but the expression of NOD2 in stageⅠandⅡwere nearly equal to that of the healthy controls (χ2 =0.36,P =0.83).The ROC analysis revealed that the best diagnostic cutoff-point of serum NOD2 levels for predicting the Ⅲ and Ⅳ stages of HCC was 148.78 pg/ml,meanwhile corresponding sensitivity was 89.1% and specificity was 77.0%.Additionally,corre-lation analysis demonstrated that there was no significant correlation between NOD2 and alpha-fetal protein (r =0.44,P =0.14).Survival curves obtained that the survival time of HCC patients with NOD2 serum concentrations≥ 200 pg/ml was significantly less than that <200 pg/ml (χ2 =15.32,P <0.05).Conclusion NOD2 is highly expressed in the serum of HCC patients,especially in advanced patients,which is possibly involved in the development of HCC and has the potential to become an effective marker used for HCC diagnosis.

Objective To evaluate the effects of a carbohydrate-electrolyte solution on serum glucose, pancreas islet function and inflammatory response in elderly patients after abdominal operation.Methods It was a prospective, randomized, double-blinded and controlled trial. Totally 40 elderly patients after abdominal operation who met the defined criteria were enrolled. The subjects in study group were administered with 1000 ml carbohydrate-electrolyte solution intravenously in consecutive three days since 1st or 2nd postoperative day. Control group was administered with 1000 ml of 10% glucose on the same method. The changes of serum glucose, insulin, C-peptide and inflammatory response cytokine (IL-6, TNF-α, CRP) were detected before and after injection.Systemic inflammatory response syndrome (SIRS) was observed.Results All the 40 patients completed the study according to the study protocol. The incremental rate of serum glucose was significantly lower in study group than in control group on the 2nd and 3rd day after administration [(4.40±2.58) mmol/L vs. (14.97±3.44) mmol/L, t=2.984, P=0.008; (2.70± 1.55) mmol/L vs. (8.11± 2.60) mmol/L, t= 5.659, P= 0.000]. The changes of insulin and C-peptide of two group were similar before and after operation. The levels of IL-6 and TNF-α were significantly lower in study group than in control group on the 3rd day after administration[IL-6: (21.76±10.40) ng/Lvs. (50.17±35.24) ng/L, t=-2.447, P=0.034; TNF-α:(23.92±14.89) ng/L vs. (51.48±42.81) ng/L, t=-2.268, P=0.043]. In study group, 6 cases experienced SIRS and 4 cases had infective complications, but in control group the numbers were 8 and 6 respectively.Conclusions Appropriate application of carbohydrate-electrolyte solution intravenously has relatively mild effects on serum glucose and inflammatory response cytokine in elderly patients after abdominal operation, it decreases incidence of SIRS and maybe decrease infective complications.

PURPOSE: The aim of this research was to evaluate the efficacy of the cystoscopic extraction and external drainage techniques for unsuccessful antegrade stenting in transplanted severe ureteral obstruction. MATERIALS AND METHODS: A total of 26 patients with severe transplanted ureteral obstruction in whom the cystoscopic extraction technique and/or external drainage technique was performed were retrospectively evaluated. After the severe obstruction was successfully traversed, balloon dilatation followed by double-J stent insertion was performed. RESULTS: Of the 26 patients (male:female, 9:4; mean age, 38.1 years) who underwent failed ureteral stenting with the conventional procedure, 16 patients underwent successful stenting with the cystoscopic extraction technique, and 10 patients underwent successful stenting following external drainage. The mean serum creatinine of the 26 patients before stenting was 42.9 mg/dL (range, 32.7 to 54.1 mg/dL), which decreased to 10.3 mg/dL (range, 8.7 to 11.8 mg/dL) after stenting. The complications of the procedure were lower abdominal pain in 22 patients and gross hematuria in 9 patients. All complications were relieved with medical care within 3 to 5 days after the procedure. No major complications occurred. CONCLUSIONS: The cystoscopic extraction technique and external drainage technique are safe and useful for traversing a severe transplanted ureteral obstruction after a failed conventional procedure.

Objective To compare the size of target volume,amplitudes of movements in different directions,movement vector,dose to the diseased lung,whole lung volume,and setup error between free breathing fixation (method A) and four-dimensional computed tomography (4DCT)-guided abdominal balloon compression fixation (method B),and to demonstrate that the 4DCT-guided abdominal balloon compression fixation is effective in the treatment of non-small cell lung cancer (NSCLC).Methods A retrospective analysis was performed among 80 patients with NSCLC in our hospital.In those patients,40 received method A and 40 method B.The GTVfree and GTVpress were delineated on the maximum intensity projection (MIP) images of 10 respiratory phases using method A and method B,respectively.The PTVfree and PTVPress were obtained by expansion of the GTVfree and GTVpress,respectively.The paired t test was used to analyze the differences in the PTV,maximum amplitudes of movements in three dimensions,absolute value of the movement vector (|V|),and volume between method A and method B.The treatment planning system was used to compare the V5,V10,V20,and V30 of the diseased lung and the whole lung volume between method A and method B.All patients underwent cone-beam CT (CBCT) scans after positioning.Setup error was obtained by matching the CBCT images with the MIP images in the XVI system based on bone and grayscale values.Results The PTVfree and PTVpress were (283.2± 12.74) and (201.8± 12.99)cm3,respectively (P=0.002).The maximum amplitudes of movements in the right-left,superior-inferior,and anterior-posterior directions as well as thel V | value were (0.22±0.02),(1.85±0.08),(0.43±0.26),and (1.91±0.27) em,respectively,for method A,and (0.05±0.01),(0.41±0.03),(0.16±0.16),and (0.44±0.16) cm,respectively,for method B (P=0.120,0.001,0.070).The V5,V10,V20,and V30 for the diseased lung and total lung volume were (61.26± 4.27) ％,(44.52± 1.70) ％,(28.22± 3.13) ％,(18.26±5.17)％,and (3556±223.12) cm3,respectively,for method A,and (52.74±4.78)％,(38.76±4.92) ％,(23.71 ±4.03) ％,(15.54±3.43) ％,and (3376±311.65) cm3,respectively,for method B (P =0.001,0.003,0.004,0.021,0.004).There was no significant difference in setup error obtained by the XVI system between the two fixation methods (P＞0.05).Conclusions Without increasing setup error,abdominal balloon compression can effectively control the lung movement amplitude,reduce the planning target volume,and reduce the radiation dose to the lung in patients with NSCLC.

Objective To explore the clinical value of serum ferritin (SF),erythrocyte sedimentation rate (ESR) and erythrocyte average indexes [mean corpuscular volume (MCV),mean corpuscular hemoglobin (MCH),mean corpuscular hemoglobin concentration (MCHC)] in the prognosis evaluation of patients with small cell lung cancer (SCLC).Methods A total of 72 SCLC patients were enrolled in the Haian People's Hospital Affiliated to Nantong University from January 2013 to October 2016 (SCLC group),and 80 health controls were selected at the same time (control group).The levels of serum SF,ESR and erythrocyte average indexes in SCLC group and control group were detected,and their relationships with clinical features,prognosis and survival time were analyzed.Results The serum levels of SF,ESR,MCV,MCH and MCHC in SCLC patients were (309 ±59) μg/L,(16 ±4) mm/h,(104 ± 12) fl,(32 ±4) pg and (307 ±21) g/L,respectively.The serum levels of SF,ESR,MCV,MCH and MCHC in control group were (186 ±26) μg/L,(15 ±5)mm/h,(85 ± 7) fl,(30 ± 3) pg and (335 ± 25) g/L,respectively.Compared with the control group,the patients in SCLC group were significantly increased on the levels of SF (t =14.168,P ＜ 0.001) and MCV (t =6.143,P ＜ 0.001),and were significantly decreased on the level of MCHC (t =-4.220,P =0.003).There were no significant difference in the levels of ESR (t =1.931,P =0.102) and MCH (t =1.220,P =0.313) between the two groups.The serum levels of SF and MCV were significantly correlated with the stage of SCLC (t =-4.092,P =0.009;t =-4.985,P ＜ 0.001).Multivariate logistic regression analysis showed that high serum SF (OR =5.31,95％ CI:3.09-9.31,P ＜ 0.001) and MCV (OR =1.78,95％ CI:1.10-3.08,P =0.013) were independent risk factors of SCLC.Survival analysis showed that the survival time of the patients in the high SF group was significantly shorter than that in the low SF group (6 months vs.20 months;x2 =6.556,P =0.001).Conclusion Serum ESR,MCH and MCHC levels are not significantly correlated with SCLC,but serum SF and MCV levels are of important clinical significance in evaluating the prognosis of SCLC patients.
