Objective To study the correlation between the polymorphism of Interferon γ( IFN-γ) ( + 874 T/A) gene and susceptibility to the development of lung cancer. Methods The polymorphism of IFN-7 gene( + 874 T/A) in 42 patients with lung cancer and 60 healthy control subjects was detected by using sequence-specific primers polymerase chain reaction( PCR-SSP) and their susceptibility to development of lung cancer was analyzed. Results The genotypic frequencies of AA of IFN -γ Gene( + 874 T/A) in the control group and the patient group were 0. 533, 0.786 .respectively and the genotypic frequency of AA in control group was significantly lower than that in the patient group ( P < 0. 01) , in contrast with which the genotypic frequencies of AT and TT in the control group were significantly higher than those in the patient group (P < 0. 01 ,P < 0.05). The A allele frequency of IFN-γ gene in the patient group was statistically higher compared with that in the control group(0. 869 vs. 0.7 ,P <0.01 ) ,in which the relative riskrate(RR) was 2.84,95%CI 1. 31 ~6.15 ,P<0. 01. Conclusion The polymorphism of IFN-γ gene ( +874 T/ A) could be associated with susceptibility to the development of lung cancer,so it could be considered one of the genetic markers to be used to early identify individuals at high risk of lung cancer.

Objective: To explore the hemostasis mechanisms of Radix Rubiae and charred Radix Rubiae.Methods: The effects of Radix Rubiae and charred Radix Rubiae were compared in terms of the clotting time,bleeding time,blood platelets count and capillary permeability on mice,and the TT,PT and APTT on pathologicalbleeding models incurred by Heparin and Warfarin and rats.Results: Radix Rubiae and charred Radix Rubiaeall canrestrain the capillary permeability of abdominal cavity in mouse,and obviously shortenthe TT,PT and APTT of rat,but charred Radix Rubiae was more effective than Radix Rubiae.The large and small doses of Radix Rubiae and the large dose of charred Radix Rubiae can elevate the blood platelets count,and obviously antagonize Heparin and Warfarin,and Radix Rubiae was more effective than charred Radix Rubiae.Conclusion: Radix Rubiae has the hemostasis effect through elevating the blood platelets count and antagonizing Heparin and Warfarin,but charred Radix Rubiae through restraining the capillary permeability and shortening the TT,PT and APTT.They have different hemostasis mechanisms.

Long non-coding RNAs (lncRNAs) , which are closely related with human critical illness, can regulate gene expression and involve the physiological and pathological processes on epigenetic, transcriptional and post-transcriptional levels through several mechanisms. LncRNAs also play important regulation roles in the maturation and differentiation process of hematopoietic cell. Besides, in-depth exploration of their mechanism will provide new ideas for the diagnosis and treatment of blood diseases.

Objective To study the effect ofoxymatrine on serum matrix metalloproteinase-9 (MMP-9)and transforming growth factor-β 1 (TGF-β 1) in patients with idiopathic pulmonary fibrosis (IPF) and illuminate the mechanism and action.Methods Total 38 patients with IPF in the patient group were divided into the conventional treatment group and the oxymatrine group by random digits table method with 19 cases each.Meanwhile 38 healthy people were as the control group.Then serum MMP-9 and TGF-β1 levels were detected by enzyme-linked immunosorbent assay and compared.Results The serum MMP-9 level in the control group and the patient group was (92.30 ± 27.21),(420.66 ± 101.78) μg/L,and there was significant difference (P ＜ 0.05).The serum TGF-β 1 level in the control group and the patient group was (67.36 ± 13.03),(217.82 ±43.90) μg/L,there was significant difference (P ＜0.05).There was no significant difference in the serum MMP-9 and TGF-β1 level before treatment between the conventional treatment group and the oxymatrine group (P ＞ 0.05).There was significant difference in the serum MMP-9 level before and after treatment in the conventional treatment group [(138.91 ± 35.09) μ g/L vs.(428.21 ±102.75) μ g/L] (P ＜ 0.05).There was no significant difference in the serum MMP-9 level before and after treatment in the oxymatrine group (P ＞ 0.05).There was significant difference in the serum TGF-β 1 level before and after treatment in the conventional treatment group and the oxymatrine group [(145.42 ± 30.78)μg/Lvs.(200.34±58.96)μg/L;(102.37±26.04) μg/Lvs.(219.78±63.20) μg/L](P＜0.05).There was significant difference in the serum TGF-β1 level after treatment between the conventional treatment group and the oxymatrine group (P＜ 0.05).Conclusion Oxymatrine can degrade IPF by reducing TGF-β 1 and maintaining MMP-9 in the higher level.

Calcium sensing receptors (CaSR) is a member of super-family of G-protein coupling receptors. This review first introduced the concept, construction features, distribution, functions, decision methods, moderators, genetic locus of CaSR and its relationship with some diseases concisely. Then this article described the investigation progress of CaSR in cardiovascular system intensively, including the expression pattern, role and signal pathways of CaSR in rat myocardium in normal, ischemia-reperfusion injury, apoptosis and cardiac hypertrophy;the role and mechanism of CaSR in calcium homostasis regulation of rat myocardium, endoplasmic reticulum (ER) stress and cardiac ischemic preconditioning and postconditioning. The metabolism rule, physiological significance and pathological action of polyamine in cardiac cells;the increase of CaSR expression in cardiac tissue of artherosclerosic rat and its effect on sensitivity to acute myocardial infarction are also discussed. In the end, the research perspective of CaSR in cardiovascular system was anticipated.

Objective To explore the role of the change of the CD11b expression in hyperleukocytosis and acute promyelocytic leukemia(APL) differentiation syndrome, we observed the effects of all-trans retinoie acid(ATRA) and trioxide arsenic(ATO) alone or the combination together with daunorubicin (DNR) on CD11b expression of human APL cell line NB4 cells. Methods By using the mono-antibody of CD11b FITC-conjugated, we monitored the level of CD11b expression of NB4 cells by flow cytometry. Results With the length of the 1 μmol/L ATRA exposure,the CD11b expression was increased. Exposed to ATRA for 24 h, 48 h, 72 h and 168 h;the CD11b expression of NB4 cell was (33.34±3.15)%, (55.59±5.13)%, (86.08±5.12)% and (90.69±2.69)%, respectively which were higher than control group and the difference was statistically significant (P<0.01). With the length of the 1 μmol/L ATO exposure, the CD11b expression showed no significant difference with control group(P>0.05), but was significantly lower than that in ATRA exposure(P<0.01). Exposed to 1 μmol/L ATRA combined with 1 μmol/L ATO for 72 h and 168 h, the CD11b expression were (18.81±1.40)% and (25.61±4.54)%, which were significantly higher than that in control group (P<0.05, P<0.01), but significantly lower than ATRA exposure (P<0.01). With the exposure to 1 μmol/L ATRA combined with 1 μmol/L ATO and 1 μmol/L DNR, the CD11b expression was also significantly lower than ATRA exposure (P<0.01) and showed no difference with control group (P>0.05). Conclusion By avoiding the increase of CD11b expression of promyelocytic leukemia cells, ATRA combined with ATO or two drugs together with DNR could play a role in eliminating incidence of hyperleukocytosis and retinoic acid syndrome.
