OBJECTIVE:To study the effects of ginsenoside CK combined with 5-fluorouracil (5-FU) on the proliferation, apoptosis and epithelial mesenchymal transition (EMT) of human pancreatic cancer PANC-1 cells. METHODS:PANC-1 cells of logarithmic growth phase were randomly divided into blank control group,ginsenoside CK group (30 mg/L),5-FU group (25 mg/L)and combination group(ginsenoside CK 30 mg/L+5-FU 25 mg/L). MTT method was used to detect the cell proliferation in-hibition rate in each group after 24,48,72 h;flow cytometry was used to detect the cell apoptosis rate after 48 h;enzyme-linked immunosorbent assay was used to detect the fibronectin expression in cells after 24,48,72,96 h;and Western blot was used to detect the expressions of vimentin,N-cadherin,E-cadherin,protein kinase(Akt)and phosphorylated Akt(p-Akt)protein in cells after 48 h. RESULTS:Compared with blank control group,the cell proliferation inhibition rate,early and late apoptotic rates,pro-tein expression level of E-cadherin in ginsenoside CK group,5-FU group and combination group were obviously increased (P<0.05),while the protein expression levels of fibronectin,vimentin,N-cadherin,and p-Akt/Akt levels were obviously decreased (P<0.05);the effects of above-mentioned indexes in combination group were superior to ginsenoside CK group and 5-FU group (P<0.05). CONCLUSIONS:Both ginsenoside CK and 5-FU can inhibit the proliferation of PANC-1 cells,induce their apoptosis and inhibit EMT,which may be associated with inhibiting phosphatidylinositol 3-kinase/Akt pathway. In addition,the combination of ginsenoside CK and 5-FU can produce a better effect.

Objective To analyze the clinical and genetic features of immunodeficiency,centromeric instability,and facial anomalies (ICF) syndrome with a case report and literature review.Methods The clinical data and genetic test of a girl diagnosed with ICF syndrome in the Department of Nephrology and Immunology in Qingdao Women and Children's Hospital in December 2016 were extracted and analyzed."ICF syndrome" "immunodeficiency,centromeric instability and facial anomalies syndrome" "ICF syndrome and DNMT3B" were used as key words to search Chinese databases and Pubmed for literature until March 2018,and the literature was reviewed.Results A female patient aged 22 months old with ocular hypertelorism and low-set ears was admitted due to recurrent infection over one year.Laboratory tests showed humoral immune deficiency with IgG＜ 1.34 g/L,IgA＜0.060 g/L,and IgM＜0.179 g/L,but normal cellular immunity (total T lymphocyte 0.503,hepler T lymphocyte 0.328,cytotoxic T lymphocyte 0.166,natural killer cell 0.184,total B lymphocyte 0.276).Whole-exome sequencing revealed a de novo heterozygous splice site mutation c.922-2A＞G in intron 8,and a de novo heterozygous missense mutation c.2477G＞A in exon 23 of DNMT3B gene.Chromosome karyotype analysis showed 46,XX,with 64 out of 100 karyotypes showing centromere instability in chromosome 1.Five papers were found which were all in English,with total of 29 patients.Forty-three mutations were reported,including 34 missense,2 deletion,1 insertion,6 splice site mutations.Eleven patients had complex heterozygosis mutations.All patients had centromere instability,humoral immune deficiency and facial dysplasia which were mainly ocular hypertelorism and low-set ears.Most patients had language and motor development delay,and a few were combined with mental retardation.Conclusions ICF syndrome is a rare autosomal recessive primary immunodeficiency with classic clinical triad manifestations.De novo mutation of DNMT3B gene is one of etiologies according to genetic test.

Objective To analyze the correlation between digital mammography features,lymphocyte to monocyte ratio(LMR)and prognosis in patient with invasive breast cancer,and to explore the prognostic value of digital mammography features and LMR in invasive breast cancer.Methods Ninety-six patients with invasive breast cancer were selected.The data of digital mammography features and serum LMR levels were analyzed.The patients were followed up after discharge.According to different prognosis,all patients were divided into good prognosis group(68 cases)and poor prognosis group(28 cases).Spearman was used to analyze the correlation of digital mammography features,LMR level and prognosis of patients.Receiver operating characteristic(ROC)curve was drawn to analyze the prognostic value of digital mammography features and LMR level.Results The spicule sign and proportion of calcifica-tion in the poor prognosis group was significantly higher than that in the good prognosis group,the maximum diameter of tumor was significantly larger than that in the good prognosis group,and the serum LMR level was significantly lower than that in the good prognosis group(P＜0.05).Spearman correlation analysis showed that spicule sign,proportion of calcification and maximum diame-ter of tumor were positively correlated with poor prognosis of invasive breast cancer(P＜0.05).Serum LMR level was negatively correlated with poor prognosis of invasive breast cancer(P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of spicule sign,calcification and tumor maximum diameter combined with LMR level to evaluate the prognosis of invasive breast cancer was 0.927,the sensitivity was 89.71％,and the specificity was 82.14％,which were significantly higher than those of each index alone.Conclusion Digital mammography and serum LMR levels may be closely related to the prognosis of patients with invasive breast cancer,and spicule sign,calcification,tumor maximum diameter combined with serum LMR may be of significant prognostic value in invasive breast cancer.
