Tumors are believed to consist of a heterogeneous population of tumor cells originating from rare cancer stem cells (CSCs). However, emerging evidence suggests that tumor may also originate from non-CSCs. To support this viewpoint, we are here to present definitive evidence indicating that the number of tumorigenic tumor cells is greater than that of CSCs in tumor, and tumor can also derive from non-CSCs. To achieve this, an idealized mathematical model was employed in the present study and theoretical calculation revealed that non-CSCs could initiate the occurrence of tumor if their proliferation potential was adequate. Further, experimental studies demonstrated that 17.7%, 38.6% and 5.2% of tumor cells in murine B16 solid melanoma, H22 hepatoma and Lewis lung carcinoma, respectively, were potentially tumorigenic. Thus, based on the aforementioned findings, we propose that the scarce CSCs, if exist, are not the sole source of a tumor.

Objective To investigate the inducing effects of selenium dioxide(SeO2 ) on the apoptosis in human cervical carcino-ma cell line Hela and its influence on the expression of apoptosis-related proteins caspase-3 and P53 .Methods Hela cells were trea-ted with different concentrations of SeO2 for 24 h in vitro ;the morphological changes of Hela cells were observed by the optical mi-croscope;the influence of SeO2 on the cell proliferation and vitality was examined by the MTT assay ;the flow cytometry was em-ployed to detect the cell apoptosis rate ;the expressions of caspase-3 and P53 proteins in Hela cells were determined by the Western blot analysis .Results Under the optical microscopy ,SeO2 generated the obvious influence on the cell growth morphology ,a large number of cells became rounded and shrunken ,and lost the normal form ,while the adherence cell number was evidently decreased and the proliferation was slowed down ;the MTT results showed that SeO2 markedly inhibited the cell proliferation and viability in a dose-dependent manner ,in which ,the cell apoptosis rates induced by the 0 ,1 .875 ,3 .750 ,7 .500 ,15 .000 and 30 .000 μmol/L con-centrations of SeO2 were 3 .12% ,30 .56% ,33 .42% ,37 .50% ,45 .43% and 69 .38% respectively ,which revealing the obviously in-creasing trend;the Western blot assay revealed that SeO2 could up-regulate the caspase-3 and P53 levels ,and reached the peak value at the concentration of 7 .500μmol/L .Conclusion SeO2 could induce the cervical cancer cell apoptosis possibly by up-regulating the expressions of caspase-3 and p53 in Hela cells .

To study the name of Wenyujin Rhizoma Concisum and Film Turmeric by literature research methods provide the basis for correct application of Cuba in modern clinical application. Wenyujin Rhizoma Concisum and Film Turmeric often called each other mutual generation and used as the same kind of medicine in the ancient prescriptions books. They were often recorded and stated as the same species of Curcumae Longae Rhizoma. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma also often called each other mutual generation in the ancient prescriptions books and used as the same kind of medicine. Wenyujin Rhizoma Concisum was often recorded and stated under the Curcumae Longae Rhizoma articles in the ancient materia medica literatures. Ancient literatures on Wenyujin Rhizoma Concisum records were almost the same, the modern literatures on the records of the sources of Wenyujin Rhizoma Concisum were inconsistency. Inconsistency of Wenyujin Rhizoma Concisum source records in modern literatures was related to the changes of the modern records on source records about Curcumae Longae Rhizoma, Root-tuber of Aromatic Curcumae Longae Rhizoma and Zedoray. The author thinks that Wenyujin Rhizoma Concisum is the ancient Film Turmeric which referes to the same medicine as Curcumae Longae Rhizoma. The source of it just as the Curcumae Longae Rhizoma is not only one kind. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma have been recorded as two medicines at the present, and the source of them simply referes to the original plant Curcuma wenyujin. When using ancient prescriptions, we need to understand the changes that Curcumae Longae Rhizoma and Wenyujin Rhizoma Concisum are the same in ancient but different today in order to choose medicine correctly in the clinical.

Objective To investigate the effect and regulation mechanism of mimic ischemia/reperfusion (I/R) cul-ture of human umbilical vein endothelial cells (HUVECs) on levels of tumor necrosis factor(TNF)-αand intercellular adhe-sion molecule (ICAM)-1. Methods HUVECs were randomly divided into four groups:control group (normal media cell cul-ture+control siRNA transfection), mimic I/R+control siRNA transfection group (HUVECs were transfected with control siR-NA, for 48 h ,and then received mimic ischemic media culture for 30 min followed by normal media culture for 4 h), normal culture+p65 siRNA transfection group and mimic I/R+p65 siRNA transfection group. The expression levels of TNF-αand ICAM-1 mRNA and protein were determined by real-time PCR and enzyme linked immunosorbent assay (ELISA), respec-tively. Results The mRNA and supernatant protein levels of TNF-αand ICAM-1 were significantly increased in mimic I/R culture group (4.96±0.16 and 3.33±0.30)μg/L than those of other tree groups (P<0.05). The level of ICAM-1 mRNA was significantly higher in I/R+p65 siRNA transfection group (1.87±0.21)μg/L than that of control group (1.58±0.15) μg/L and normal culture+p65 siRNA transfection group [(1.69±0.21)μg/L, P<0.05]. The levels of TNF-αand ICAM-1proteins were (329.98 ± 12.18) μg/L and (654.74 ± 64.79) μg/L in mimic I/R+control siRNA transfection group, which were significantly higher than those of other three groups (P<0.05). The levels of TNF-αand ICAM-1 proteins were (129.65±22.42)μg/L and (185.76±11.27)μg/L in mimic I/R+p65 siRNA transfection group, which were significantly lower than those of contro group [(183.50±11.77)μg/L and (280.43±13.76)μg/L, P<0.05]. Conclusion The silencing of p65 through transfection of p65 siRNA in HUVECs inhibited mimic I/R-induced mRNA and protein expressions of TNF-αand ICAM-1.

Objective Cerebral small vessel disease is closely related to kidney disease .Chronic kidney disease ( CKD) may increase the risk of hemorrhage stroke .However, its impact on hemorrhage-prone small vessel disease represented by cerebral microb-leeds( CMBs) remains unclear .The purpose of this study was to investigate the relationship of CKD with the presence and location of CMBs in patients with acute lacunar stroke . Method Consecutive patients with acute lacunar stroke within 7 days from onset were enrolled retrospectively from January 2014 to July 2016 and scanned by gradient-echo T2*-weighted imaging (GRE-T2*WI).Their demographic, clinical, laboratory and imaging data were collected .Estimate glomerular filtration rate (eGFR) was calculated individu-ally by the following chronic kidney disease epidemiology collaboration (CKD-EPI) equation for the Asian population .CKD was defined as the level of eGFR<60 mL/min/1.73 m2. Results Finally, 308 patients (mean age:65.79±8.67 years; median NHISS:3(2-5);42.2%Female) with lacunar ischemic stroke were enrolled in the final analysis .Among these patients, CMBs were present in 116 patients ( 37.7%) and CKD in 62 patients ( 20.1%) .Patients were divided into CKD group and normal group according to GFR level . The result of univariate analysis showed that patients with CKD had higher prevalence of diabetes ( P=0.014) and higher degrees of CMBs (P=0.001) compared with normal group.CMBs were refined by its location .The result of multivariable analysis showed that CMBs in deep brain [ OR=7.61, 95%CI 4.18-16.55, P=0.001] were sig-nificantly associated with CKD incidence , while no significant rela-tionship was found in CKD incidence and CMBs in the lobe and mixed location of brain . Conclusion The CKD incidence in patients with acute lacunar stroke is in dependent relationship with CMBs in deep brain and without significant correlation with CMBs in the lobe and mixed location of brain .

Objective To analyze the relationship between different rectal volume,bladder volume and dose of organs at risk (OARs) in intracavitary brachytherapy for cervical cancer.Methods A total of 47 patients with cervical cancer were selected.All of them were treated with high dose rate (HDR) intracavitary brachytherapy with a 600 cGy dose for the dosage point.The effects of different volume of rectum bladder and small intestine for corresponding exposure dose under the standard planning were evaluated using a dose-volume histogram (DVH).According to bladder volume,patients were divided into three groups,＜ 80 cm3 group,80-120 cm3 group and ＞ 120 cm3 group.And according to rectum volume,patients were divided into ＞ 60 cm3 group and ≤ 60 cm3 group.The relationship between the volume and dosage were analyzed.The ANOVA test and t test were used for analyzing D1 cm3,D2 cm3,D30％ and D50％.Results Compared with the group with ＜ 80 cm3 bladder volume,D30％,D50％ value of bladder in groups with 80-120 cm3 and ＞ 120 cm3 of bladder volume increased (F =5.074,5.088,P ＜ 0.05).The difference of D1 cm3 and D2 cm3 value of the small intestine between 80-120 cm3 and ＞ 120 cm3 bladder volume groups were not statistically significant (P ＞ 0.05).D1 cm3 of rectum in groups with ≤ 60 cm3 rectum volume was decreased than that of ＞ 60 cm3 group (t =-2.045,P ＜ 0.05).Conclusions Keeping an appropriatly full bladder and reducing rectal volume in cervical cancers treated with intracavitary brachytherapy can make the exposure dose of bladder,rectum and small intestine relatively small,and reduce the adverse reactions of radiotherapy.

Immuno-fluorescence technique can qualitatively determine certain nuclear translocation, of which NF-κB/ p65 implicates the activation of NF-κB signal pathways. Immuno-fluorescence analysis software with independent property rights is able to quantitatively analyze dynamic location of NF-κB/p65 by computing relative fluorescence units in nuclei and cytoplasm. We verified the quantitative analysis by Western Blot. When we applied the software to analysis of nuclear translocation in lipopolysaccharide (LPS) induced (0. 5 h, 1 h, 2 h, 4 h) primary human umbilical vein endothelial cells (HUVECs) , we found that nuclear translocation peak showed up at 2h as with calculated Western blot verification results, indicating that the inventive immuno-fluorescence analysis software can be applied to the quantitative analysis of immuno-fluorescence.
