1.Research progress on genetic susceptibility to lung cancer
Cancer Research and Clinic 2016;28(3):203-206
Lung cancer is currently one of the most common malignant tumors in the world, with an increasing trend of morbidity and mortality.The major causes of lung cancer are inhaled carcinogens, such as tobacco and environmental pollution, but a growing number of researches suggest that the incidence of lung cancer is closely related to genetic factors.In the past few years, great progress has been made in research on single nucleotide polymorphism of susceptibility gene in lung cancer, and the most studies that have aimed to ultimately provide scientific basis for preventing and controlling the lung cancer have focused on screening of lung cancer etiology and developing gene therapy.In this review, the new findings of genetic susceptibility in lung cancer have been summarized.

Dexamethasone is a synthetic glucocorticoid that is widely used in clinical due to its multiple pharmacological effects. Recently, dexamethasone is increasingly utilized in anti-cancer therapy. It is frequently used to prevent side effects of chemotherapy such as nausea, vomiting and pain, as well as to increase the anti-tumor activity of the cancer chemotherapeutic agents as a chemosensitizer and to inhibit tumor growth as an anti-cancer agent in some certain cancers. Dexamethasone produces the effects in anti-inflammation, anti-angiogenesis, control of estrogen activity and so on, by binding to glucocorticoid receptor to regulate gene expression of some important bio-signal molecules. Those signal pathways could interfere with the transcription of various factors which can regulate proliferation, invasion and metastasis of tumors.

Objective To study the protective role of continuous veno-venous hemofiltration (CVVH) in cardiac insufficiency refractory to diuretic therapy after acute myocardial infarction.Methods A total of 104 acute myocardial infarction patients admitted from march 2012 to march 2016 were recruited.According to their wishes,the patients were divided into two groups,continuous veno-venous hemofiltration combined with routine therapy as experimental group (n =52) and conventional treatment as control group (n =52).Mortality rate within one month,the mean length of ICU stay,the mean length of hospital stay,ventilator usage and urine output volume were documented.Then the difference in BW between pre-and post-treatment was determined for evaluation of fluid retention,and blood plasma C-reactive protein (ΔCRP),interleukin 6 (ΔIL-6),interleukin 8 (ΔIL-8),tumor necrosis factor-α (ΔTNF-α) and left ventricular ejection fraction (ΔLVEF) were measured and calculated.A multiple linear regression model to predict ΔLVEF was established.Data recorded at different intervals in the same group were analyzed by ANOVA.Data of the monitoring biomarkers,the mean length of ICU stay,the mean length of hospital stay of two groups were recorded at the same given intervals were analyzed by t test.Data of mortality rate within one month,drugs and ventilator usage in two groups were analyzed by x2 test.P value less than 0.05 was considered statistically significant.Results There were significant differences in mortality rate within one month,the mean length of ICU stay,the mean length of hospital stay,and the duration of ventilator usage between the two groups (P < 0.05).Total volume of fluid output (urine and ultrafiltration volume) was higher in experiment group than that in control group in 48 hours after the treatment (P < 0.01).The levels of CRP,IL-6,IL-8 and TNF-α decreased significantly (P < 0.05) in experiment group after treatment but not in control group (P > 0.05) as compared with those before the treatment.BW was decreased and LVEF was increased in both groups after treatment (P < 0.05) compared with those before the treatment.Levels of CRP,IL-6,IL-8 and TNF-α were lower in experiment group than those in control group after treatment (P < 0.05).BW was meagerly lower and LVEF was meagerly higher in experiment group than those in control group without statistical significance (P > 0.05).However,the degrees of ΔLVEF andΔBW were greater in experiment group than those in control group (P < 0.01).In experiment group,significantly positive correlations were found among ΔBW,ΔCRP,ΔIL-6,ΔIL-8,ΔTNF-α and ΔLVEF (P <0.05).Multiple linear regression analyses showed that ΔBW and ΔTNF-α were the independent factors forΔLVEF and ΔBW was the main independent factor for ΔLVEF in control group.ΔLVEF was positively correlated with ΔBW (P<0.01) but had no correlation with ΔCRP,ΔIL-6,ΔIL-8 and ΔTNF-α (P >0.05).Multiple 1inear regression analyses showed that only ΔBW was the independent factor for ΔLVEF.Conclusion CVVH plays protective role in acute myocardial infarction patients with consequent cardiac insufficiency refractory to diuretic therapy by clearance of inflammatory cytokines and removal of retained fluid,and the removal of retained fluid is the most import mechanism to protect heart function.

Objective To investigate whether there are correlations between working memory impairmentand fractional anisotropy values and to explore the neuropathology underlying that the patients of depression suffered from memory impairment.Methods Thirty depression patients and 30 healthy controls group-matched by age,educational level were conducted the study.Mean correct reaction time(mRT)was recorded when they performed a One-Back Working Memory Task and fractional anisotropy(FA)values was recorded when they performed the diffusion tensor imaging.Statistics analysis was done respectively for mRT and FA values between two groups.Results Relative to mean correct reaction time((612.45±54.08)ms)of controls,the mean correct reaction time ((720.25±57.02)ms)of patients with depression was much longer(P<0.05)and the patients with depression had a lower FA values in the white matter of both frontal lobe,anterior cingulate gyrus,supramarginal gyrus,splenium of corpus callosum(P<0.05),and the FA values in the white matter of both frontal lobe were significantly negative correlated with mRT(r=-0.604,P<0.05).Conclusion The impairment of white matter region may be one of the neuropathology underlying that the depression patients suffer from memory impairment.

Objective To investigate the effects of inhibition of STAT5 gene expression by RNA interference technology on apoptosis of human hepatocellular carcinoma cell line SMMC-7721. Methods Three siRNA eukaryotic expression vectors against STAT5 were constructed and transfected with lipofectamineTM 2000 into SMMC-7721 cells. The changes in STAT5 expression were detected by semi-quantitative RT-PCR and Western blot. Cell apoptosis was assayed by flow cytometry (FCM). Results The sequence-specific siRNA could effectively and specifically inhibit STAT5 gene expression at both mRNA and protein levels. The inhibition rates of STAT5 mRNA expression were 70.43%, 43.02%, and 45.07%, respectively. The inhibition rates of STAT5 protein expression were 67.45%, 37.36%, and 41.86%, respectively. At 48 h after transfection, apoptosis rate was 25.61%. Conclusion siRNA against STAT5 can inhibit STAT5 gene expression in SMMC-7721 cells effectively and specifically and induce apoptosis of SMMC-7721 cells. siRNA targeting STAT5 has a great potential value in gene therapy of hepatocellular carcinoma.

Objective To investigate the effect of periplocin of cortex periplocae (CPP) on Stat3 signaling and its probable molecular mechanism of inducing apoptosis and anti-tumor activity. Methods Cell proliferation was detected by MTT. Cell apoptosis and cell cycle were investigated by flow cytometry. Expression of Stat3 protein in SMMC-7721 cells was analyzed by Western blot. Mcl-1, Survivin and XIAP mRNA expressions were measured by RT-PCR. Results CPP inhibited the proliferation of SMMC-7721 cells significantly, induced their apoptosis and arrested their cell cycle at G2/M phase. Decreased expression of Stat3 protein in the cell nucleus was observed after CPP treatment, but no significant changes were found in cytoplasma. Mcl-1, Survivin and XIAP mRNA expression levels were decreased in a time-dependent manner. Conclusion CPP inhibits cell proliferation and induces apoptosis by inhibiting Stat3 signal transduction in human hepatocellular carcinoma cell line SMMC-7721.
