Objective To study the expression of RUNX3 mRNA in primary liver cancer (PHC) tissue and its surrounding normal tissue,and its clinical significance.MethodsReverse transcription polymerase chain reaction (RT-PCR) was performed to detect the expression of RUNX3 mRNA in tumor and peritumor tissues in 51 patients with PHC.The relationship between RUNX3 mRNA expression and some clinical pathological parameters was analyzed.ResultsThe relative expression values of RUNX3 mRNA in the tumor tissue and the surrounding normal tissue were 0.4509±0.0963 and 0.9147± 0.0222,respectively.The difference was significant (t=33.6087,P＜0.001).The RUNX3 mRNA expression in tumor tissue correlated with some clinical pathological parameters including low tumor differentiation,positive cancer embolus and intrahepatic invasion and metastasis.The RUNX3 mRNA expression was not correlated with other clinicopathological parameters including gender,cancer diameter,cancer location,hemorrhage and necrosis of cancer,and histotype.ConclusionRUNX3 may be a new tumor suppressor gene for PHC.

Objective To observe the effect of acupuncture therapy of regulating Yin and Yang for the treatment of stroke,and to investigate the influence on plasma levels of calcitonin gene-related peptide(CGRP) and vascular endothelin(ET).Methods One hundred and twenty stroke patients were equally randomized into 3 groups: group A received acupuncture therapy of regulating Yin and Yang,group B received traditional body acupuncture therapy,and group C received scalp acupuncture therapy.One and a half months constituted one treatment course,and the treatment lasted 2 courses.The therapeutic effect was evaluated and the changes of plasma CGRP and ET levels were observed.Results The total effective rate was 95.0% in group A,85.0% in group B,and 82.5% in group C,the difference being significant between the three groups(P0.05).Conclusion Acupuncture therapy of regulating Yin and Yang exerts a certain effect for the treatment of stroke,and can up-regulate plasma CGRP level and decrease ET level.

OBJECTIVE To study the period of validity of iodine skin disinfectant povidone-iodine(Iodophor) in different seasons,different hours and different using frequency.METHODS In spring and summer respectively,the iodine was used for 10 days continually after the bottle opened.Then,the sample drawing from bottle was detected for iodine content,pathogenic bacteria and contamination of bacteria quantification.RESULTS The available iodine content was coming down gradually with the increasing in usage time and frequency.And the changing in the content differed in spring and summer.Microorganism was not found in povidone-iodine under using time,different seasons and using frequency.CONCLUSIONS The skin disinfectant can be used for 10 days at least under standard range after begining using.

Background Corneal neovascularization (CNV) is one of the causes of corneal blindness.Studies showed that ADP-ribosylation factor (ARF) can regulate the growth of tumor cells,and inhibiting ARF will decrease angiogenesis.However,whether ARF antagonist plays an action on CNV is unclear.Objective The aim of this study was to explore the effect and mechanism of ARF inhibitor on alkali-burn induced CNV.Methods Sixty clean male BABL/c mice aged 7-8 weeks were divided into PBS group and ARF antagonist group according to randomized number table.CNV models were induced by NaOH burn method in all the mice.ARF at the concentration of 0.5 g/L(0.5 ml) was intraperitoneally injected 3 times per week for 1 week followed the induction of CNV in the ARF antagonist group,and 0.5 ml PBS was used in the PBS group.CNV was examined 2,4,7,14 days after injection by the slit lamp microscope and the CNV related area in the cornea was calculated.Betore modeling(0 day) and 4,7,14 days after modeling,real-time PCR and Western blot were used to analyze the expressions of ARF mRNA and protein in the corneas.Forteen days after modeling,the expression of the CD31 in the CNV was detected using immnofluorescence of corneal whole mount;the expression of vascular endothelial growth factor(VEGF) in the cornea was assayed by Western blot.Cellular wound scratch test was employed to evaluate the effects of ARF antagonist on proliferation and migration of human retinal vascular endothelial cells (RECs).All animal experiments were done in accordance with the ARVO Statement for the Use of Animals in Ophthalmic and Vision Research and Guideline for the Care and Use of Laboratory Animals on the the Soochow University Animal Care Committee.Results ARF mRNA and protein were expressed in the mice corneas in both the PBS group and the ARF antagonist group at various time points.The expression of ARF mRNA in mice corneas was enhanced with the lapse of the time (Ftime =65.17,P =0.00),but no significant difference was found among the groups (Fsroup =1.98,P=0.18).There was also significant difference in the expression of ARF protein in mice corneas at different time points in the ARF antagonist group (F =10.77,P =0.00).The related CNV area was 0.45±0.05 in the ARF antagonist group,and that in the PBS group was 0.72±0.11,with significant difference between them (t =-3.87,P ＜ 0.05).The green fluorescence area of C D31 expression in the cornea was smaller in the ARF antagonist group than that of the PBS group.Expression level of VEGF in the ARF antagonist group was 1.20±0.21,and that in the PBS group was 2.47±0.33,showing a significant difference (t =-5.62,P ＜ 0.05).As the increase of ARF antagonist concentration,the inhibiting rate of cell proliferation was reinforced among 10,100 and 1 000 μg/L ARF antagonist groups (F=8.47,P =0.02).Twenty-four hours after scratch test,the migrating distance of human RECs was (5.46±1.32) μm and (5.04±1.68) μm in the 100 μg/L and 1 000 μg/L ARF antagonist groups,respectively,which were shorter than (8.49± 1.18) μm of the PBS group (t=-2.94,-2.91,both at P＜0.05).Conclusions ARF inhibitor can reduce CNV by down-regulating the expression of VEGF in alkaline burn cornea and inhibiting the proliferation and migration of vascular endothelial cells.

This paper is to report the development of a rapid and sensitive method for the determination of s-oleylpropanolamide (OPA) in various tissues of rat (brain, heart, lung, liver, spleen, small intestine, kidney, adipose tissue and muscle), and to assess the applicability of the assay to tissue distribution. OPA was extracted by liquid-liquid extraction method with undecylenoylethanolamide as an internal standard. The concentrations of OPA were determined by LC-MS/MS after a single intragastric dose of 50 mg x kg(-1) at 4 time points (5 rats per group). With multiple reactions monitoring mode (MRM) the limit of quantification (LLOQ) was determined at 1 microg x L(-1). The calibration curve was linear from 1 to 2 x 104 microg x L(-1) (r > or = 0.999 0) for tissue homogenates. Validation parameters such as accuracy, precision and recovery were found to be within the acceptance criteria of the assay validation guidelines. The highest concentration was found in small intestine (the highest time point is 15 min) and heart (the highest time point is 90 min). The assay is rapid, sensitive and applicable to studying tissue distribution of OPA in rats.

ObjectiveTo evaluate the effect and safety of recombinant human erythropoietin (rhEPO) in treatment of lung cancer chemotherapy-related anemia.MethodsNinety-eight lung cancer chemotherapy-related anemia patients were divided into treatment group and control group with 49 cases each by random digits table method.The patients in treatment group were given rhEPO and chalybeate.The patients in control group were merely given chalybeate.The hemoglobin (Hb),hematocrit,allogeneic blood transfusion rate and quality of life between two groups were observed and compared.ResultsThree cases were rejected in treatment group,and 3 cases with anergy and dizzy and 2 cases with local injection site pain and sclerosis recovered spontaneously.Hb and hematocrit showed downward trend after treatment in control group,but there was no significant differences (P ＞ 0.05).Hb and hematocfit had upgrade trend after treatment in treatment group,and there were significant differences between after 4 - 8 months treatment and before treatment (P ＜ 0.05 ).The allogeneic blood transfusion rate was 24.5％ (12/49) in control group and 6.5％ (3/46) in treatment group,and there was significant difference between two groups (P ＜ 0.05 ).The quality of life in treatment group was increased compared with that in control group.There were significant differences in the effective rate after 4 or 8 weeks treatment between two groups [52.2％(24/46) vs.6.1％(3/49) and 95.7％ (44/46) vs.20.4％ ( 10/49 )].ConclusionsrhEPO is effective and safe in treatment of lung cancer chemotherapy-related anemia.rhEPO has little adverse reaction and can improve the quality of life.
