OBJECTIVE Angiogenesis therapy has attracted interest as a potential treatment for hepatocellular carcinoma (HCC). In this study, we investigated the anti-proliferative activities and anti-angiogenesis effects of saikosaponins (SS)-b on hepatocellular carcinoma (HCC) and its regulation on VEGF/ERK/HIF-1α signal pathway. METHODS H22 hepatoma-bearing mice model and HepG-2 cells were used to study the anti-tumor and anti-angiogenesis effects of SS-b in vivo and in vitro. Pathological change of tumor tissue was observed by HE staining, the microvascular changes were detected by immunohistochemical method. The effects of SS-b on angiogenesis were examined by using the chick embryo chorioallantoic membrane (CAM) model. The effects of SS- b on proliferation, migration and invasion were investigated by MTT assay, scratch wound healing assay and transwell assay inhuman umbilical vein endothelial cell (HUVEC) and HepG2 cells in vitro. Vascular endothelial growth factor (VEGF), matrix metalloproteinase-2/9(MMP-2/9), hypoxia-inducible factor-1α (HIF-1α) expression and the phosphorylation of extracellular regulated kinase(ERK) were analyzed using RT-PCR and Western-blot. RESULTS SS-b effectively inhibited the tumor growth of H22 mice in vivo. The inhibitory rate of tumor was 49.1%, 50.7%, 66.1% in SS-b 5, 10 and 20 mg·kg-1 group respectively. HE staining results showed that SS-b induced tumor necrosis and nuclear dissolution in H22 mice. Moreover, SS-b also reduced the number of microvessels of tumor tissue in H22 mice significantly and suppressed the angiogenesis of CAM induced by b-FGF. SS-b had an obvious inhibitory effect on cell proliferation, migration and invasion of HUVEC cells and HepG-2 cells. These effects were associated with down-regulation of the expression of MMP2/9 and suppression of VEGF/ERK/HIF-1α signaling in H22 mice and Hep-G2 cells. CONCLUSION Our findings showed that SS-b exerts anti-tumor effects by inhibit?ing tumor angiogenesis via regulating VEGF/ERK/HIF-1α signal pathway in vivo and in vitro.

Objective The study was carried out to investigate the effects of different dietary Ca levels on bone metabolism, based on the osteoprotegerin ( OPG)-receptor activator of NF?κB ligand ( RANKL)?receptor activator of NF?κB ( RANK) system in growing WHBE rabbits. Methods Twenty one weaned male WHBE rabbits at the age of 42 days were divided into 3 groups (I, II and III) according to dietary Ca levels (0. 95%, 1. 10%, and 1. 30%, respectively) for a 42?d feeding trial. The above three diets had similar phosphor (P) (about 0. 64 g/kg), digestible energy (9. 50 MJ/kg), crude protein (about 19. 70%) and crude fibre (13. 57%) contents. When the feeding trial finished, the serum in?dices of bone metabolism (Ca, PTH and BALP) were detected, and the OPG?RANK?RANKL system in bone tissue was analyzed by real?time fluorescence quantitative PCR assay and immunohistochemistry, respectively. At last, the relationships between bone metabolism and dietary Ca were evaluated according to RANKL/OPG ratio. Results All the contents of serum Ca, PTH and BALP had no significant differences in the groups I, II and III (P>0. 05). Both the RANKL mR?NA and RANKL/OPG mRNA ratio were lowest in the group II and had significant differences with group I and III ( P<0. 05). Dietary Ca levels had significant effects on the protein expression of OPG?RANK?RANKL in bone tissues (P<0. 01). The positive index of OPG in the groups II and III was significantly higher than that in the group I(P<0. 01), while the positive index of RANK in the group II was lower than those of the group I and III(P<0. 01). The protein ex?pression positive index ratio of RANKL to OPG was also lowest in the group II, showing a significant difference with group I(P<0. 01). Furthermore, both the gene transcription ratio of RANKL to OPG and the protein expression positive index ratio of RANKL to OPG had significant correlations (with quadratic curve) to the dietary Ca levels (R2 =0. 4068, 0. 8433;P<0. 05,P<0. 001). Conclusions In summary, the bone metabolism of WHBE rabbits during growing periods has sig?nificant correlation with dietary Ca levels. An optimal bone metabolism status can be obtain at 1. 10% dietary Ca level as demonstrated in this study.

BACKGROUNDThis study was to examine the expression of total vascular endothelial growth factor (VEGF) and the anti-angiogenic VEGF 165 b isoform in the vitreous body of retinopathy of prematurity (ROP) patients, and to further study the role of the VEGF splicing in the development of ROP.

METHODSThis was a prospective clinical laboratory investigation study. All patients enrolled received standard ophthalmic examination with stage 4 ROP that required vitrectomy to collect the vitreous samples. The control samples were from congenital cataract patients. The expression of total VEGF and the anti-angiogenic VEGF 165 b were measured by enzyme-linked immunosorbent assay. Results were analyzed statistically using nonparametric tests.

RESULTSThe total VEGF level was markedly elevated in ROP samples while VEGF 165 b was markedly decreased compared to control group. The relative protein expression level of VEGF 165 b isoform was significantly decreased in ROP patients which were correlated with the ischemia-induced neovascularization.

CONCLUSIONSThere was a switch of VEGF splicing from anti-angiogenic to pro-angiogenic family in ROP patients. A specific inhibitor that more selectively targets VEGF 165 and controls the VEGF splicing between pro- and anti-angiogenic families might be a more effective therapy for ROP.

OBJECTIVE: To explore the genetic basis for a child with developmental delay and congenital syndactyly. METHODS: G-banding chromosomal karyotyping and chromosomal microarray analysis (CMA) were performed on peripheral blood sample from the child. RESULTS: The child was ascertained as 46, XY, r(18)[52]/45,XY,?18[3]. A 18q21.32-q23 deletion was identified by CMA with a size of 19.85 Mb, which has encompassed 99 genes including CTDP1, TXNL4A, TSHZ1, PIGN, RTTN, TNFRSF11A, KDSR and CYB5A. CONCLUSION Clinical phenotype of the patient with ring chromosome 18 is associated with the size of the euchromatin loss and involved genes. As a useful complement to conventional karyotyping, CMA has provided an powerful tool for delineating complex chromosomal aberrations.

OBJECTIVE To examine the synergistic inhibiory effect of combination of mammalian target of sirolimus (Rapamycin) (mTOR) inhibitor everolimus and AKT inhibitor MK-2206 on hepatocar-cinoma cell proliferation. METHODS HepG2 and BEL-7402 cells were treated with sirolimus and evero-limus alone for 0, 1, 3, 6, 12 and 24 h or in combination with insulin-like growth factor 1 receptor (IGF-1R) inhibitor NVP-AEW541 or AKT inhibitor MK2206 for 24 h. p70S6K and AKT kinase activityies were detected by Western blotting. Plate clone formation assay and CCK8 assay were used to detect the growth and proliferation of hepatocarcinoma cells treated with everolimus and MK2206 alone or in combi-nation. RESULTS Sirolimus and everolimus inhibited p70S6K activity while causing feedback activa-tion of AKT kinase activity at different time points (P<0.01). NVP-AEW541 and MK-2206 could inhibit AKT kinase feedback activation by everolimus (P<0.05). Colony formation of hepatocarcinoma cells treated with everolimus and MK-2206 in combination was significantly inhibited compared with everolimus or MK-2206 alone (P<0.01). Everolimus and MK-2206 in combination inhibited the proliferation rate of two types of hepatocarcinoma cancer cells by more than 45％ compared with everolimus used alone (P<0.01). CONCLUSION The resistance of sirolimus and its derivatives in hepatocellular carcinoma cells may be achieved throngh the feedback-activated PI3K/AKT pathway, and the combination therapy can synergistically inhibit the growth and proliferation of hepatocarcinoma cells.

OBJECTIVE: To explore the genetic basis for a child featuring short stature. METHODS: G-banded karyotyping, chromosomal microarray analysis (CMA) and high-throughput sequencing were carried out on peripheral blood sample from the child. RESULTS: The karyotype of the child was ascertained as 45,XY,-4[3]/46,XY,r(4)(p16q35)[84]/47,XY,-4,r(4)(p16q25)*2[7]/48,XY,-4,r(4)(p16q35)*3[1]/46,XY,dic r(4;4)(p16q35;p16q35)[2]/46,XY,add(4)(p16)[3]. A 647 kb deletion at 4p16.3 was identified by CMA, which encompassed 6 OMIM genes including ZNF141, PIGG, PDE6B, ATP5I, PCGF3 and MYL5. High-throughput sequencing has identified no pathogenic/likely pathogenic variants consistent with the clinical symptoms. CONCLUSION A rare ring chromosome 4 syndrome was identified by combined chromosomal karyotyping, CMA and high-throughput sequencing. Conventional cytogenetic analysis and genetic testing in combine have enabled the diagnosis in this case.
