Background and purpose:Ovarian cancer is associated with a high recurrence and mortality due to the existence of cancer stem cells. The purpose of this study was to investigate the effect of casticin (CAS) on the capability of self-renewal in ovarian cancer stem cell like cells (OCSLCs) derived from SKOV3 cell line. Methods:SKOV3 cell line cells were cultured in vitro, and OCSLCs were obtained and amplified through suspended culture with conditioned medium of the stem cells. The phosphorylation level of FoxO3a was analyzed using Western blot. The protein expression of FoxO3a was inhibited by FoxO3a speciifc siRNA transfection, and then the ratio of sphere-formation was detected. Results: Compared with parental cells, OCSLCs over-expressed phosphorylated FoxO3a (pFoxO3a) and had elevated ratio of sphere-formation [(3.1±0.3)% vs (34.8±6.8)%, P<0.05]. CAS significantly inhibited the capability of sphere-formation in OCSLCs and down-regulated the expression level of pFoxO3a. And the transfection of FoxO3a speciifc siRNA suppressed the protein expression of FoxO3a and attenuated the inhibitory effect of CAS on the sphere-formation of OCSLCs. Conclusion: Reduced expression level of pFoxO3a is involved in the effect that CAS inhibits sphere-formation of OCSLCs derived from SKOV3 cell line.

Background Oxygen-induced retinal neovascularization is the main pathological basis for many retinal vascular diseases.Research showed that light exposure at night can suppress retinal neovascularization in oxygen-induced retinopathy(OIR),but there were few reports discussing its effect on ROP.Objective This study aimed to observe the effect of light exposure at night on retinal neovascularization in an OIR mouse model.Methods Sixty-four newborn C57 BL/6J mice were randomly divided into four groups,with 16 mice for each group.OIR models were established by rearing the newborn C57BL/6J mice with their mothers in a(75±2)％ oxygen environment from postnatal day 7(P7)to Pl2,and then transferred to room air.In the OIR model group,the environmental illumination level was the same as the normal control group,and the model mice were exposed to 100 lx light at night in the OIR+ light exposure group.In the simple light exposure group,normal mice were reared in room air and were exposed to light at night from P12 to P17.All the mice were sacrificed on P17,and retinal flat mounts were prepared to assess the oxygen-induced changes of retinal vessels using the adenosine diphosphatase(ADPase)histochemical technique.The amount of proliferative neovascularization was quantified by counting the number of endotheliocyte nuclei in new vessels extending from the retinal inner limiting membrane into the vitreous in ocular cross-sections.The expression of the vascular endothelial growth factor(VEGF)protein was detected by immunohistochemistry.Real-time PCR analysis was performed to examine the expression of VEGF mRNA.The rearing and usage of the animals complied with the Statement of ARVO.Results Less free-vascular areas and new blood vessels were seen in the OIR+light exposure group compared with the OIR model group.On day 17 of the mouse life,the number of the endotheliocyte nuclei in new vessels extending from retinal inner limiting membrane were 0.97±0.83,1.00±0.72,38.57±5.01 and 16.92±3.39 in the normal group,simple light exposure group,OIR model group and OIR+light exposure group,respectively,showing significant differences among them(F =78.767,P =0.000).The number of nuclei in the OIR+light exposure group were less than that of the OIR model group(t=20.446,P＜0.01).Immunochemistry showed that the expression of VEGF in retina was weaker in the OIR+light exposure group than the OIR model group.The relative expression values of VEGF mRNA were 1.00±0.00,0.94±0.07,2.08±0.50 and 1.43±0.21 in the normal group,simple light exposure group,OIR model group and OIR+light exposure group,respectively,showing a significant difference (F=11.268,P =0.003),where the VEGF mRNA level in the OIR+light exposure group was lower than that of the OIR model group(t =20.163,P＜0.05).Conclusions Light exposure at night can weaken retinal neovascularization in OIR mice

Objective To investigate the distribution status of coal-burning fluorosis (endemic fluorosis) areas in Luoyang and to provide scientifc evidence for making strategies in prevention and control. Methods In 2006, a household per village was chosen to carry the general survey so as of disease condition, living habits and housing structure among 941 coal-burning pollution fluorine sickness natural villages in Yanshi, Mengjin, Xin'an, Luanchuan counties and Geely area which were under the jurisdiction of Luoyang. In the general survey, the sampled village having a population of more than 500 person was considered as a major survey village, and water fluoride, 8 - 12 year-old child fluorine spot on tooth and the urinary fluoride were surveyed. Water fluoride and the child urinary fluoride determination used the fluoride ion selective electrode method, and the children's dental fluorosis used Dean method. Results The endemic fluorosis of Luoyang existed 742 in endemic fluomsis villages, compared with history, a decrease of 199 in number. Ninety-six point seven per cent( 142 543/147 419) of the households were consuming smoke-free coal. Households using intact kitchens accounted for 93.6%( 137 919/147 419). Of which 63.0%(86 889/137 919) of kitchens were mixed up with bedrooms. Total 125 060 people were using coal- fired furnace for heating, of which 87.8%(109 802/125 060) had smoke-free facilities, 12.2%(15 258/125 060) had none. Among 52 endemic villages with population of more than 500 people surveyed, a total of 183 water samples were collected, 2 had water fluoride exceeding 1.0 rag/L, the highest water fluoride being 1.04 rag/L, averaging 0.39 mg/L Sixteen villages had a prevalence rate of dental fluorosis for children less than 30.00%, accounting for 30.8% (16/52), 36 endemic villages the prevalence of dental fluorosis detection rate of more than 30.00%, accounting for 69.2%(36/52). Twenty-thrce villages had a dental fluorosis index greater than 0.6, severe dental fluorosis was not found. Real-time measurement of 1408 urine samples of children aged 8 - 12 showed that urine fluoride highest value 6.88 nag/L, the minimum value of 0.10 mg/L, geometric mean 1.10 mg/L. The prevalence rate of dental fluorosis for children was 36.06%. Conclusions In Luoyang city, numbers of coal-burning endemic fluorosis villages are less than before, children's dental fluorosis has significantly declined, however some people still use kitchens connecting with bedrooms and lack smoke-free facilities, they need to be educated to change lifestyle and improve furnace to reduce soot fluoride pollution.

Objective To explore the bioeffects of canine myocardium under microbubble destruction via diversity of ultrasonic intension, in order to optimize ultrasonic intension for experiments. Methods Nine mongrel dogs were randomly divided into 3 groups. Ultrasound (1 MHz) in diversity of different intension (0.5 W/cm~2, 1.0 W/cm~2, 2.0 W/cm~2) was applied to expose canine myocardium after intravenous injection microbubbles of 2.0 ml. All the dogs were killed after being exposed for 5 min. The myocardium was harvested for HE staining and observed with transmission electron microscope for the tissue microstructures. Results The myocardium of hyperemia, disfiguration and necrosis wer observed in all groups. Myocardial edema but not hemorrhage appeared with 0.5 W/cm~2 , mild myocardial hemorrhage and slight inflammatory cell infiltration happened with 1.0 W/cm~2, whereas obvious hemorrhage and certain degree of inflammatory cell infiltration occurred with intension of 2.0 W/cm~2. With the augmentation of ultrasonic intension, myocardium trend to aggravate. Conclusion Ultrasound of diversity intension can induce different bioeffects of canine myocardium. Ultrasound mediated microbubble destruction with the intensity of 1.0-2.0 W/cm~2 can provoke a certain degree of inflammatory reaction with mild myocardial damage.

OBJECTIVEThe efficiency network is a complicated network for revealing the efficient mechanism of traditional Chinese medicines (TCMs) and relations among efficiencies. The efficiency-property relations were used to establish a warm-pungent-liver efficiency network to explain the principle of treating hepatoma with medicines invigorating blood circulation and eliminating blood stasis. Safflower, a warm-pungent medicine distributing along the live meridian, was taken for example to discuss the efficiency network' s application in the identification of active ingredients of TCMs and the combination.

METHODIn the early stage of this study, combined warm-pungent-liver medicines distributed along the liver meridian and invigorating blood circulation and eliminating blood stasis were taken as the study objects to collect the pharmacological effect data of warm-pungent-liver medicines and obtain the pharmacological effect combinations with the highest blood circulation-invigorating association by the association rules and the chi-square test. The pharmacological target data recorded in the DrugBank database is used to establish the warm-pungent-liver efficiency network according to the principle line of "efficiency-property-pharmacology-target-protein interaction" under the background of the protein interaction network.

RESULTThe blood circulation-invigorating medicines could directly treat hepatoma by impacting protooncogene, cancer suppressor gene, cell apoptosis and anti-inflammation, and indirectly treat hepatoma by resisting coagulation and adhesion, regulating local blood circulation, preventing cancer cell metastasis and enhancing the tissues' sensitivity to the anticancer drugs. Among the active ingredients of safflower screened based on the blood circulation-invigorating network targets, carthamin yellow, quercetin and luteolin have been proved to have the anti-hepatoma effect in literatures, which indicated the reliability of this study's results and the purpose of the efficiency network.

CONCLUSIONThe efficiency network is an effective method for revealing the TCM's mechanism, and lays a foundation for discovering key active ingredients of TCMs for treating specific diseases.
