Objective To explore the effect of calreticulin (CRT) on cell proliferation and invasion of human hepatocellular carcinoma cell line SMMC-7721 and HepG2.Methods SMMC-7721 and HepG2 cells were transfected with small interfering RNA (siRNA).The transfection rate was detected by immunoflurescence and western blot.The cell proliferation,invasion and apoptosis of SMMC-7721 and HepG2 cells were determined by using cell counting kit-8 (CCK-8) assays,transwell assays and flow cytometry,respectively.The p-Akt and Akt levels were detected by western blot.Results The growth inhibition rate in the siRNA experimental group of SMMC-7721 and HepG2 cells for 24,36 and 48 h were (41.0 ±2.2) ％,(46.5 ±1.6)％,(59.7 ±2.2)％ and (36.8 ±2.7)％,(47.3 ± 1.8)％,(61.5 ±3.2)％,respectively.The apoptosis rate after down-regulating the expression of CRT in SMMC-7721 and HepG2 cells for 36h were (45.2 ± 9.1) ％ and (48.9 ± 8.0) ％,respectively.Compared with the blank group and the negative control group,the growth inhibition rate in the siRNA experimental group was lower (P ＜0.05),but the apoptosis rate was significantly higher (P ＜ 0.05).Transwell experiments confirmed that the numbers of invaded SMMC-7721 and HepG2 cells in the blank group and the negative control group and siRNA experimental group were (96.8±7.3),(95.6±5.4),(34.0±4.2) and (124.0 ±9.9),(121.6 ±7.0),(70.4±9.5),respectively,indicating that cell invasion in the siRNA experimental group was significantly suppressed (P ＜ 0.05).The expression of p-Akt was decreased (P ＜ 0.05) after down-regulating the expression of CRT for 36h.Conclusion CRT gene silencing by siRNA can inhibit the SMMC-7721 and HepG2 cell proliferation and invasion,but increase the cell apoptosis by regulating PI3K/Akt signal pathway.

BACKGROUND:For patients with rheumatoid arthritis and Kümmel ’s disease, how to effectively control back pain, to recover patient’s locomotor activity and to avoid a vicious cycle of disuse osteoporosis is a key therapeutic target. Kyphoplasty is a recently developed new technology of minimal y invasive spine surgery. Few reports concerned the kyphoplasty for rheumatoid arthritis and Kümmel ’s disease. OBJECTIVE:To assess the clinical outcome of bone cement kyphoplasty for the treatment of Kümmel ’s disease combined with rheumatoid arthritis. METHODS:From June 2012 to July 2013, 11 female patients at the age of 65.4±5.1 years with Kümmel ’s disease combined with rheumatoid arthritis, who suffered from severe back pain, were treated with bone cement vertebroplasty. Back pain and imaging indexes were compared and observed before surgery and during fol ow-up. Imaging indexes contained preoperative and postoperative anterior height of vertebral body after fractures, the ratio of anterior height to posterior height of the vertebral body, and local kyphosis angle (Cobb method). RESULTS AND CONCLUSION:No patients were lost to fol ow up. 11 patients were fol owed up for 6 to 12 months. Significant differences in fol ow-up and preoperative Visual Analogue Scale scores, anterior height of vertebral body after fractures, the ratio of anterior height to posterior height of the vertebral body, and local kyphosis angle were detected (P<0.05). Two patients experienced bone cement leakage. No severe complications appeared such as pulmonary embolism or neurological dysfunction. These data confirmed that bone cement vertebroplasty for rheumatoid arthritis combined with Kümmel ’s disease can effectively lessen back pain, partial y restore the height of vertebral body after fracture, rebuild spinal stabilization, reduce local kyphosis, and is a safe effective repair method.

Objective To study the expression and the clinical significance of hypoxia-induced factor-1α (HIF-1α) in gallbladder cancer tissues,and the role and mechanism of HIF-1α in metformin-suppressed metastasis in gallbladder carcinoma GBC-SD cells.Methods 24 specimens of gallbladder cancer tissues and 5 specimens of chronic cholecystitis were collected from the First Affiliated Hospital of Zhengzhou University between June 2016 and February 2017.Immunohistochemistry and qPCR were used to detect the expression of HIF-1α in gallbladder cancer tissues,in adjacent non-cancer tissues and in chronic cholecystitis,and the clinical significance was analyzed.The model of metastasis was induced by hypoxia;the wound healing assay and the Transwell assay were used to detect the ability of cell metastasis;the expressions of HIF-1α and VEGF in gallbladder carcinoma GBC-SD cells were detected by western blotting assay and immunofiuorescence.Results The expression of HIF-1α in gallbladder cancer tissues was higher than the adjacent non-cancer tissues and in chronic cholecystitis.The expression of HIF-1α was correlated with lymph node metastasis and TNM staging in gallbladder cancer tissues (P ＜ 0.05).The wound healing rate after 48 h in the negative control group and in the treatment with hypoxia group (1％ O2) in GBC-SD cells were (46.5 ± 4.8) ％ and (67.3 ± 4.0) ％,respectively.The Transwell data showed that the numbers of metastasis after 24 h in the negative control group and in the treatment with hypoxia group GBC-SD cells were (147.4 ± 11.7) and (234.4 ± 17.7),respectively.When compared with the negative control group,treatment with hypoxia significantly increased the ability of metastasis and up-regulated the expression of HIF-1α and VEGF in GBC-SD cells (P ＜ 0.05).The wound healing rate after 48 h in the negative control group,the metformin group,the hypoxia group and the metformin and hypoxia group in GBC-SD cells were (40.6 ± 7.1) ％,(16.4 ± 9.4) ％,(69.5 ± 4.0) ％ and (22.4 ± 7.4) ％,respectively.The Transwell data showed that the numbers of metastasis after 24 h in the negative control group,the metformin group,the hypoxia group and the metformin and hypoxia group in GBC-SD cells were (148.4 ± 6.9),(90.0 ± 8.4),(185.8 ± 10.2) and (113.4± 8.6),respectively.When comparcd with the hypoxia group,treatment with metformin and hypoxia significantly decreased the ability of metastasis and down-regulated the expression of HIF-1α and VEGF in GBC-SD cells (P ＜ 0.05).The wound healing rate after 48 h in the negative control group,the 2MeoE2 group,the hypoxia group,the 2MeoE2 and hypoxia group in GBC-SD cells were (43.4 ±4.4)％,(25.9 ±9.0)％,(63.3 ±2.2)％,(46.2 ±4.5)％,respectively.The Transwell data showed that the numbers of metastasis after 24 h in the negative control group,the 2MeoE2 group,the hypoxia group,the 2MeoE2 and hypoxia group in GBC-SD cells were (144.2 ± 12.6),(80.2 ±7.7),(203.8 ±7.0),(124.0 ± 5.2),respectively.When compared with the hypoxia group,treatment with HIF-1α inhibitor 2MeoE2 and hypoxia significantly decreased the ability of metastasis and down-regulated the expression of HIF-1α and VEGF in GBC-SD cells (P ＜ 0.05).Conclusions The expression of HIF-1 α was correlated with lymph node metastasis and TNM staging in gallbladder cancer tissues.Treatment with hypoxia significantly increased the expression of HIF-1α and VEGF and promoted metastasis of GBC-SD cells,while treatment with metformin decreased the ability of metastasis induced by hypoxia via inhibiting the HIF-1o/VEGF pathway in GBC-SD cells.

Objective To observe the effect of acute hypervolemic hemodilution (AHH) with two kinds of hydroxyethyl starches including Voluven and HES on the renal function of emergency surgery patients with brain injury.Methods This study involved 54 brain injury patients treated with emergency surgery,who were randomly divided into Voluven group ( AHH130 group),HES group ( AHH200 group) and Ringer's lactate group (LR group),with 18 patients in each group.All the patients were managed with inhalation anesthesia.ECG,MAP,CVP and SpO2 were observed in operation.The blood urea nitrogen (BUN),urine creatinine ( BCr,UCr),urinary albumin (ALB) and urinary α1-microglobulin ( α1-MG) were detected before AHH ( T0 ),at the end of operation ( T1 ),at 4 hours ( T2 ),day 1 ( T3 ),day 2 (T4) and day 3 (T5) after operation.The creatinine clearance (CCr) and fractional sodium clearance (FSC) were calculated and the urine output,fluid replacement,blood loss and blood transfusion recorded.Results The HR,CVP and MAP in the three groups were within the normal range of variation at all time points,with statistical difference for comparison between groups and within group ( P ＞ 0.05 ).There was no significant difference in urine output and blood loss,while the intraoperative fluid volume and blood transfusion in the AHH130 group and the AHH200 group were significantly less than those in the LR group (P ＜ 0.01 ).There was no statistical difference in aspects of BUN,BCr and urinary ALB at each time point between and within the three groups ( P ＞ 0.05 ).After treatment with AHH,the urinary α1-MG level in the AHH130 group and AHH200 group was significantly increased ( P ＜0.01 ),which was decreased at T5 but was still higher than that at T0 ( P ＜ 0.01 ),and was higher than that in the LR group at all time points (P＜0.05).After treatment with AHH,CCr was decreased in the AHH130 group and AHH200 group,which reached the lowest level at T2,with statistical difference compared with the levd at T0 ( P ＜0.01 ).Then,CCr was recovered to normal at T5.FSC in the three groups after AHH treatment was increased slightly and the most significantly at T2,which was not statistically different compared with that at T0 ( P ＞ 0.05) and FSC was not statistically different between and within groups at other time points (P ＞0.05).All the values about the renal function in all the groups changed within the normal range at each time point.Conclusions AHH with Voluven or HAES is a feasible and safe blood conservation measure that can significantly reduce the allogeneic blood transfusion but exert insignificant effect on renal function of the brain injury patients with normal renal function before emergency surgery.

Objective To assess the cardiovascular events after percutaneous transluminal coronary intervention (PCI) and the influence of fluvastatin on inflammation factors and prognosis of PCI patients.Methods One hundred and eighty-seven patients whose coronary stenosis ≥ 70% diagnosed through coronarography and underwent PCI from Jun.2005 to Feb.2008 were recruited in the current study.These patients were divided into two groups,the control group (n =91) was treated regularly and the treat group (n =96) was treated with additionally fluvastatin(40 mg/d).Fasting venous blood was obtained before and after medicine treatment,12,24 hours and two weeks after PCI.IL-18,IL-6 and TNF-α were measured through ELISA.Results Before medicine treatment,there were no difference of IL-18 ,IL-6 and TNF-α between the two groups( P ＞ 0.05 ).After medicine treatment,IL-18,TNF-α and IL-6 decreased significantly compared to those before treatment in both groups ( P ＜ 0.05 ),and these measurements decreased more in the treatment group ( P ＜ 0.01 ).At the 12th hours after PCI,IL-18,TNF-αand IL-6 in the control group increased to (423.5 ± 298.7 ),( 316.1 ± 72.6 ) and (42.3 ± 10.1 ) ng/L,respectively,and arrived the peak at the 24th hour,which were significantly higher than those before medicine treatment( P ＜ 0.01 ).In the treatment group,these measurements at the 12th and 24th hour after PCI were slightly higher than those before medicine treatment without significant difference ( P ＞ 0.05 ).After 12 hours ofPCI,IL- 18,TNF -αand IL-6were (276.5 ± 189.4 ),( 175.3 ± 51.9) and ( 10.1 ± 8.1 ) ng/L,which were significantly lower than those in the control group(P ＜ 0.01 ).Two weeks after PCI,IL-18,TNF-α and IL-6 in the treatment group were (137.0 ±34.2),(35.1 ± 21.6) and ( 8.7 ± 3.2 ) ng/L,which were significantly lower than before medicine treatment ( P ＜0.01 ).Conclusions PCI may aggravate the inflammation response of coronary artery.Statins may alleviate the inflammation response.IL-18,TNF-α and IL-6 are sensitive indices of early inflammation response after PCI,their changes might have prediction value for adverse cardiovascular events.Therefore these indices might be used as a target in the statins treatment in the primary prevention,as well as the evaluation of the effectiveness of PCI,statins and joint PCI and statins.

Objective To investigate the levels and clinical significance of pentraxin 3 (PTX3) and high sensitive C-reactive protein(Hs-CRP) in patients with chronic obstructive pulmonary disease (COPD).Methods Seventy COPD patients at acute exacerbation stage were selected as the acute exacerbation group,70 COPD patients at disease remission stage were selected as remission group,and 70 healthy subjects were selected as control group.According to pulmonary function,70 COPD patients at acute exacerbation stage were divided into mild-to-moderate group(37 cases) and severe-to-very severe group (33 cases).The serum levels of PTX3,Hs-CRP,white blood cell count (WBC),neutrophils (NE) were measured.Results The serum levels of PTX3,Hs-CRP,WBC and NE of the acute exacerbation group and remission group [(0.89 ± 0.38) μg/L,(52.14 ± 4.25) mg/L,(12.13 ± 4.78) ×109/L,(79.68 ± 9.02)％;(0.47 ± 0.12) μg/L,(10.28 ± 3.42) mg/L,(8.02 ± 3.24) × 109/L,(67.24 ± 8.02) ％] were higher than those of the control group [(0.18 ± 0.04) μg/L,(4.42 ± 2.02) mg/L,(4.97 ± 2.57) × 109/L,(63.38 ± 8.79) ％] (t =213.252,245.168,48.647,53.241;121.426,124.352,21.425,24.352,all P ＜0.05).The serum levels of PTX3,Hs-CRP,WBC and NE of the acute exacerbation group were higher than those of the remission group (t =89.435,93.214,18.325,16.325,all P ＜ 0.05).In COPD patients at acute exacerbation stage,the serum levels of PTX3,Hs-CRP,WBC and NE of the mild-to-moderate group and severe-to-very severe group [(0.77 ±0.32) μg/L,(41.23 ±3.74) mg/L,(8.24 ±4.48) × 109/L,(71.54 ±8.73)％;(1.13 ±0.43) μg/L,(59.32 ± 4.65) mg/L,(14.21 ± 5.02) × 109/L,(87.96 ± 9.36) ％] were significantly higher than those of the control group [(0.18 ± 0.04) μg/L,(4.42 ± 2.02) mg/L,(4.97 ± 2.57) × 109/L,(63.38 ± 8.79) ％](t =43.253,314.265,53.241,67.324;47.315,289.253,46.572,63.241,all P ＜ 0.05).The serum levels of PTX3,Hs-CRP,WBC and NE of the severe-to-very severe group were higher than those of the mild-to-moderate group (t =38.942,267.425,46.537,58.932,all P ＜ 0.05).There was positive correlation between serum PTX3 and Hs-CRP,WBC,NE in COPD patients at acute exacerbation stage (r =0.532,0.498,0.697,all P ＜ 0.05).The serum Hs-CRP was positively correlated with WBC and NE (r =0.542,0.713,P ＜ 0.05).Conclusion Serum levels of PTX3 and Hs-CRP are elevated in patients with COPD.The serum levels of PTX3 and Hs-CRP are associated with disease severity.

Objective: To explore the clinical efficacy of S-1 single agent adjuvant chemotherapy for the patients undergoing radical resection of extrahepatic biliary carcinoma. Methods: The clinical data of 108 patients with extrahepatic biliary carcinoma receiving radical resection who were admitted from January 2014 to June 2017 were retrospectively analyzed. There were 62 males(57.4%)and 46 females(42.6%),with a median age of 59 years (range:26 to 79 years),10 cases(9.3%) in stage Ⅱ,85 cases(78.7%) in stage Ⅲ, and 13 cases (12.0%) in stage Ⅳ, 40 cases(37.0%) of hilar cholangiocarcinoma, 8 cases(7.4%) of middle cholangiocarcinoma, 25 cases (23.2%) of distal cholangiocarcinoma, 35 cases(32.4%) of gallbladder carcinoma.After radical resection of extrahepatic biliary carcinoma, 49 patients receiving S-1 single agent chemotherapy and 59 patients receiving non-special treatment were divided into the chemotherapy group and the operation group,respectively. All the dates of the patients were followed up and collected with the overall survival time,tumor-free survival time,1,2 and 3-year survival rate after operation,and the rate of major toxic reaction during chemotherapy of the chemotherapy group. Survival curve was drawn by the Kaplan-Meier method, and survival analysis was done using the Log-rank test. Results: There were no significant differences in the general date of two groups(sex, age, tumor size, tumor site, TNM stages, degree of differentiation). The median overall survival time and the median tumor-free survival time in the chemotherapy group were 27 months and 21 months,respectively,and in the operation group were 21 months and 17 months,respectively. There were differences between the two groups in the overall survival rates(χ²=3.967,P<0.05) and the 2 and 3-year survival rate(63.3%,36.6%;41.6%,20.4%;χ²=4.510,P<0.05;χ²=6.143,P<0.05),but the 1-year overall survival rate (83.4%,79.7%)was not statistically significant(χ²=0.286,P>0.05). There were no significant differences in the tumor-free survival time,1,2 and 3-year tumor-free survival rate(77.6%,41.4%,33.1%;62.7%,30.9%,21.2%)between the two groups(χ²=0.876,P>0.05;χ²=0.252,P>0.05;χ²=1.571,P>0.05;χ²=3.323,P>0.05,respectively). The main toxic reaction during chemotherapy were dyspepsia(28.6%, 14/49), anemia(26.5%, 13/49), and leukopenia(22.5%, 11/49), all of which were mild. Conclusion S-1 single agent chemotherapy after radical reseetion of extrahepatic biliary carcinoma could effectly improve the survival of patients and all of the main toxic reaction during chemotherapy were mild.
