ABSTRACT

【Objective】 To investigate the effect of lentinan on Sorafenib resistance in hepatocellular carcinoma (HCC) cells BEL-7402/S and its mechanism. 【Methods】 CCK-8 method was used to detect the proliferation-toxicity of lentinan and Sorafenib on BEL-7402 and BEL-7402/S cells, and the drug resistance reversal multiple of Sorafenib. The effects of lentinan on mRNA and protein expressions of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor (HIF-1α) in BEL-7402/S cells were determined by RT-qPCR and Western blotting. 【Results】 Lentinan reduced the proliferation of BEL-7402 and BEL-7402/S cells. Lentinan showed at least a partial reversal of drug resistance to sorafenib in BEL-7402/S cells and down-regulated the mRNA and protein expressions of VEGF and HIF-1α in BEL-7402/S cells. 【Conclusion】 Lentinan can partially reverse the effect of BEL-7402/S cells on Sorafenib resistance, and the mechanism may be related to the down-regulation of VEGF and HIF-1α expressions.

ABSTRACT

【Objective】 To explore the effect of negative elongation factor E(NELFE) on the invasion and migration of triple-negative breast cancer(TNBC) cells and its mechanisms. 【Methods】 qRT-PCR was used to detect the expression of negative elongation factor E(NELFE) in triple-negative breast cancer(TNBC) tissues and adjacent tissues. NELFE expression was upregulated in MDA-MB-231 cell lines via lentivirus transfection. Transwell assay was used to observe the effect of elevated NELFE expression on the migration and invasion of MDA-MB-231 cells. The RNA stability assay was used to detect the influence of NELFE on the stability of the mRNA of N-myc downstream regulated gene2(NDRG2). Western blotting analysis was used to detect the regulatory function of NELFE on NDRG2 protein expression. 【Results】 NELFE expression was increased in TNBC tissues. After the overexpression of NELFE, the migration and invasion of MDA-MB-231 cells were significantly enhanced, NDRG2 mRNA stability was decreased, and NDRG2 protein expression level was downregulated. NDRG2 expression was upregulated in MDA-MB-231 cell lines with overexpressed NELFE; cell migration and invasion abilities were decreased. 【Conclusion】 NELFE inhibited NDRG2 expression by decreasing the stability of NDRG2 mRNA and promoted the migration and invasion of TNBC cells.

ABSTRACT

Objective:To evaluate the effect and possible mechanism of B-cell-specific moloney murine leukemia virus insertion site 1(BMI-1) on the radiosensitivity of pancreatic cancer SW1990 cell line.Methods:According to our previous study results, 4 Gy X-ray and down-regulation of BMI-1 expression were adopted as intervention conditions. The effect on the proliferation of SW1990 cells was assessed by clony formation assay. The effect on cell apoptosis and cell cycle was evaluated by flow cytometry. The effect upon the epithelial-mesenchymal transition (EMT) was determined by Western blot.Results:Clony formation assay and flow cytometry found that the lowest cell proliferation ability and the highest apoptotic rate were obtained after BMI-1 down-regulation and 4 Gy X-ray compared with other groups (all P<0.05). Flow cytometry revealed that the proportion of G 0/G 1 phase was significantly decreased, whereas the G 2/M phase was remarkably increased in pancreatic cancer stem cells treated with 4 Gy X-ray compared with the control group (both P<0.05). Nevertheless, opposite results were obtained after down-regulation of BMI-1 expression. Western blot showed that the expression of E-cadherin was up-regulated, whereas that of Vimentin was down-regulated following 4 Gy X-ray (both P<0.05). Conclusion:Downregulation of BMI-1 expression can enhance the radiosensitivity of pancreatic cancer SW1990 cells, and its mechanism may be related to cell cycle and EMT.

ABSTRACT

Objective@#To study the prevalence of high-risk HPV (HR HPV) in women who accepted cervical cancer screening in Beijing and its distribution in cervical precancerous lesions.@*Methods@#From January 2014 to March 2015, all women aged 35-64 years old and received free screening in institutions of cervical cancer in Beijing were recruited. Stratified cluster random sampling method was used in selecting 31 091 women for gynecological examination and genotyping of HR-HPV. Those positive for HR-HPV (except for HPV 16/18) were examined for cervical cell. For those atypical squamous cells of uncertain significance (ASCUS) and above, who were positive for HPV 16/18 and with uncertain results for cervical cell, were transferred for colposcopy examination. For those with suspicious or abnormal results for colposcopy, were transferred for histopathology. The prevalence of HR-HPV, cervical cancer and precancerous lesions among the participants were analyzed.@*Results@#Totally 31 091 women aged from 35-year-old to 64-year-old, with 44.3% (13 780 women) in the 35-49 age group and 55.7% (17 311 women) in the 50-64 age group. 66.1% (20 536 women) were rural women. The infection rate of HR-HPV was 7.4%(2 305 cases) among the women. High-risk infection rates of HPV except HPV 16/18 were 5.7% (1 758 cases), and multi-infection rate was 1.5% (477 cases). The highest infection rate was 7.9% (1 044 cases) among the 45-49 year-old and 50-54 year-old age groups (χ2=14.07, P=0.015). The rate in rural women was significantly higher than that of the urban women (6.2%, 507 cases; 7.9%, 1 798 cases) (χ2=25.75, P<0.001). The proportion of HPV16, HPV18, HPV52, HPV51, HPV58 was 17.0% (391 cases), 6.9% (161 cases), 8.6% (20 cases), 5.2% (12 cases) and 7.7% (18 cases), respectively. The detection rate of cervical cancer and precancerous lesions in the population was 395.6/100 000 (123 cases). In high-grade squamous intraepithelial lesions (HSIL), HPV16 and 18 infections accounted for 60.5% (72 cases) of all. HPV16 infection rate and detection rate of HSIL were the highest in 50-54 year-old group which were 1.5% (107 cases) and 25.2% (30 cases) (χ2=11.54, P=0.042).@*Conclusion@#Top five types of HR-HPV infection in women who accepted cervical cancer screening in Beijing were HPV16, 18, 52, 51 and 58. The infection rate of HPV16 and 18 increased significantly in HSIL women. HPV16 infection rate and detection rate of HSIL were the highest in 50-54 year-old age group.

ABSTRACT

To investigate the impact of goal directed analgesia on the outcome of patients with mechanical ventilation in intensive care unit. A total of 126 patients who needed mechanical ventilation were recruited. With a method of before and after paired comparison, they were divided into two group:( 1 ) analgesia with empirical administration or control group; ( 2 ) goal directed analgesia based on critical-care pain observation tool (CPOT). Compared with the control group, after goal directed analgesia was applied, the consumption of midazolam significantly dropped from ( 368. 47 ± 27. 41 ) mg to ( 151. 27 ± 29. 31 ) mg (P<0. 05), whereas the consumption of dexmedetomidine significantly increased from ( 623. 62 ± 20. 91) μg to (812. 34 ± 22. 57) μg(P<0. 05). The median score of Richmond agitation-sedation scale increased from -3 to -1. The incidence of delirium significantly reduced from 23. 81% to 17. 46%( P<0. 05). The mean ventilator duration was significantly shortened from (168. 49 ± 11. 41) h to (142. 38 ± 13. 24) h(P<0. 05). ICU length of stay was significantly shortened from (23. 64 ± 9. 26) d to (19. 63 ± 8. 46) d ( P < 0. 05 ) . Due to the mild sedation, patients receiving goal directed analgesia report less delirium, less ventilation time and shorter ICU length of stay, suggesting that the general outcome is improved.

ABSTRACT

OBJECTIVE To study the genetic polymorphisms of Penta E locus in Fujian Han population. METHODS Polymorphisms of the Penta E locus in 851 unrelated individuals were analyzed using polymerase chain reaction-short tandem repeat (PCR-STR). The mutation rate of rare alleles was analyzed in 494 paternity identification cases (in a total of 674 meiosis). RESULTS Twenty-six alleles were identified for the Penta E locus, with their frequencies ranging from 0.0006 to 0.1528. There were 7 rare alleles, among which Penta E-28.4 ([AAAGA]29) was identified for the first time. Genetic parameters of the Penta E locus in Fujian Han population were obtained, including PIC= 0.91, PE= 0.817, PD= 0.986, and mutation rate= 0.0015. CONCLUSION The Penta E locus is highly polymorphic and has a low mutation rate in Fujian Han population. It also has a good prospect in genetics applications. DNA sequencing is a good method for identifying rare alleles.

Objective To explore the correlation of pulse pressure(PP) and outcome in refractory septic shock patients.Methods A total of 68 patients with refractory septic shock consecutively admitted in our ICU from January 2012 to December 2012 were retrospectively studied.Hemodynamic data and arterial lactate concentration were collected at the time of admission and 24 hours after admission.The outcome of Day 28 post-diagnosis was also recorded.Results (1) Compared with the survivors,heart rate(HR) at 24hours after admission was higher in non-survivors,while 24 h lactate clearance rate (rLac) was lower in them (P < 0.05).Other hemodynamic parameters showed no difference between the non-survivors and the survivors at 24 hours after admission,including central venous pressure (CVP),mean arterial pressure (MAP),systolic blood pressure(SBP),diastolic blood pressure(DBP),PP,pulse pressure/heart rate (PP/HR),pulse pressure/mean arterial pressure(PP/MAP),pulse pressure/systolic pressure(PP/SBP),pulse pressure/diastolic pressure (PP/DBP),the value of SBP above MAP (SMP) and the value of DBP below MAP(MDP).(2)The mortality rate was higher in the patients with HR≥100 b/min than those with HR < 100 b/min,but without statistical significance (56.25% vs 36.11%,P =0.096).Compared with the survivors,no matter with HR≥100 b/min or HR < 100 b/min,lactate(Lac) at the 24 hours after admission was higher in all the non-survivors (P < 0.05),while with lower rLac (P < 0.05).In those with HR ≥100 b/min,the following hemodynamic parameters were higher in the non-survivors than in the survivors,including PP,PP/HR,PP/MAP,PP/SBP,PP/DBP,SMP and MDP (all P values < 0.05),while no statistical difference was observed in those with HR < 100 b/min.(3)The mortality rate showed no statistical difference in those with MAP≥85 mmHg(1 mmHg =0.133 kPa) and with MAP < 85 mmHg(42.42% vs 48.57%,P =0.611).No matter MAP≥85 mmHg or MAP < 85 mmHg,compared with the survivors,all the non-survivors had higher Lac at the 24 hours after admission (P < 0.05),while with lower rLac (P < 0.05).In those with MAP≥85 mmHg,HR was higher in the non-survivors than the survivors (P < 0.05).In those with MAP < 85 mmHg,compared with the survivors,the non-survivors had higher PP,PP/MAP,PP/SBP,PP/DBP,SMP and MDP (P <0.05),while with lower DBP (P <0.05).Conclusion PP is correlated with the outcome in refractory septic shock patients.When the HR and MAP differ,PP has different effect on the outcome and contributes more to the tissue perfusion and outcome in those with higher HR and lower MAP.

ABSTRACT

Objective To observe the effect of neoadjuvant chemotherapy for patients with advanced cervical cancer.Methods According to the digital table ,106 patients with advanced cervical cancer were randomly divided into the two groups ,53 cases in each group .The observation group was given TP Scheme neoadjuvant chemotherapy before surgery ,the control group underwent surgery directly .The total effective rate of chemotherapy and the changes of diameter of tumor before and after chemotherapy were observed .The serum levels of vascular endothelial growth fac-tor(VEGF) and matrix metalloproteinase-9(MMP-9) of the observation group were detected ,and the operation condi-tions were compared between the two groups .Results After chemotherapy ,the total effective rate of the observation group was 60.4%.Before and after chemotherapy ,the average tumor diameter of the observation group was (5.24 ± 1.35)cm,(2.64 ±0.67)cm,respectively,the difference was significant (t=3.947,P<0.05).The operative time, blood loss and lymph node metastasis in the observation group were significantly less than those in the control group (t=3.725,5.392,χ2 =4.28,P<0.05 or P<0.01).After chemotherapy,the serum levels of VEGF and MMP-9 were significantly lower than that before chemotherapy (t=3.130,4.724,all P<0.05).Conclusion Neoadjuvant chemotherapy in the treatment of advanced cervical cancer can significantly reduce serum VEGF and MMP-9 expression.

ABSTRACT

Background and purpose:The recurrence and metastasis of gastric cancer seriously affect survival in patients.SOX gene as a regulatory factor of the classical Wnt pathway, may play an important role in the process. This study was to explore the expression of stem cell marker SOX-2 and β-catenin in gastric cancer and to analyze the relationship with recurrence and metastasis after operation.Methods:Immunohistochemistry was used to detect the expression of SOX-2 and β-catenin in 71 tumor samples from 71 cases after surgery for gastric cancer. The correlation between SOX-2 and β-catenin expression and the clinicopathological characteristics of gastric cancer and disease-free survival was analyzed.Results:The SOX-2 protein expression was associated with metastasis, lymph node inifltration or differentiation (P=0.011,P=0.036,P=0.034) in the 71 gastric cancer, but not with gender, age or T stage. β-catenin expression was correlated with metastasis, lymph node invasion or T stage (P=0.025,P=0.014,P=0.026), but was not related to differentiation, gender or age. The survival analysis showed that SOX-2 and β-catenin expression was closely associated with prognosis of patients, and metastatic rate in positive expression was higher than that in negative expression.Conclusion:The expression of SOX-2 and β-catenin is associated with the development, recurrence, metastasis of gastric cancer and may be used as a useful prognostic parameter to predict overall survival.
