Background and purpose:One of the reasons why cancer cells are resistant to chemotherapy is the existence of cancer stem cells. The purpose of this study was to investigate the chemoresistance of CD44+/CD24+ Siha cells to cisplatin and its mechanisms.Methods:Siha cells were cultivatedin vitro. The CD44+/CD24+ Siha cells were sorted out by fluorescence activated cell sorter (FACS) andin vitro proliferation was detected by MTT assay after treatment with the different concentrations of cisplatin. The cell apoptosis rate was detected by flow cytometry after 10 μg/mL cisplatin acted on CD44+/CD24+ Siha cells for 24, 48 and 72 h. The relative mRNA and protein expressions of Bcl-2, Oct-4 and ABCG2 were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot, respectively. Results:The survival rates of CD44+/CD24+ Siha cells treated with different concentrations of cisplatin (0.1, 1, 5, 10, 15 and 20 μg/mL) were higher than those of their parental Siha cells [(88.42±1.51)%vs (92.87±1.5)%, (79.94±1.05)%vs (84.72±1.09)%, (69.78±0.81)%vs (75.13±2.86)%, (58.97±0.70)%vs (65.79±2.71)%, (49.60±0.88)%vs (52.10±0.52)%, (45.13±0.69)%vs (48.84±1.02)%,P<0.05]. Compared with their parental Siha cells, the apoptosis rates of CD44+/CD24+ Siha cells were lower after 10 μg/mL of cisplatin acting on them for 24, 48 and 72 h, respectively [(3.05±0.16)%vs (5.17±0.27)%, (17.94±2.02)%vs (32.60±4.28)% and (40.14±3.01)%vs (56.62±5.32)%,P<0.05]. The results from both qRT-PCR and Western blot indicated that Oct-4, ABCG2 and Bcl-2 were highly expressed on CD44+/CD24+ Siha cells. A significant difference was found in Oct-4, ABCG2 and Bcl-2 expression between CD44+/CD24+Siha cells and their parental cells (P=0.015<0.05).Conclusion:CD44+/CD24+ Siha cells could be resistant to apoptosis induced by cisplatin and expressed high levels of cancer stem cell markers such as Oct-4 and ABCG2. This study lays the basis for useful isolation and further targeted therapy of cervical cancer stem cells.

Objective To explore whether CD44 +/CD24 + expressing cervical cancer cells are resistant to X-ray irradiation and investigate the underlying mechanism.Methods Cervical cancer cell line (Siha) was cultured in vitro and the CD44 +/CD24 + expressing cells were sorted with a flow cytometer.The cells were irradiated with 8,16 and 30 Gy of 6 MV X-rays.Colony formation test was used to evaluate the radiosensitivity of CD44 +/CD24 + expressing cervical cancer cells.Cell morphology was observed by electronmicroscopy,cell apoptosis was analyzed with a flow cytometer and also verified with a DNA ladder assay.Gene expression was determined by RT-PCR.Results After radiation,the ratio of CD44 +/CD24 + cells significantly increased.Compared to Siha cells,the radiosensitivity of CD44 +/ CD24 + cells decreased (t =93.99-400.45,P ＜0.05),and the expressions of bcl-2,survivin and Oct4 mRNA increased in CD44 +/CD24 + cells (t =221.35,941.65,82.27,P ＜0.01).Both apoptotic body and specific DNA ladder pattern were observed in cells but not in the CD44 +/CD24 + Sihacells which had no obvious morphological changes of apoptosis.Conclusions The CD44 +/CD24 + expressing cervical cancer cells are resistant to X-rays due to expression of anti-apoptosis factors.

OBJECTIVETo identify risk factors of hepatocellular carcinoma (HCC) in cirrhotic patients with chronic hepatitis B (CHB).

METHODSA total of 715 cirrhotic patients with CHB were recruited from the Zhongshan Hospital Affiliated to Fudan University and enrolled in this case-control study between January 2009 and September 2014. All participants were Chinese Han residing in Shanghai and the surrounding areas. The patients were divided into a cirrhosis group (n =281) and a HCC group (n=434). History of hepatitis B infection and HCC, as well as clinical data from serological, imaging and pathological examinations were collected for analysis.SPSS software, version 19.0, was used for all statistical comparisons.

RESULTSSingle factor analysis indicated that development of HCC in cirrhotic patients with CHB was significantly associated with male sex, age of 50 years or more, family history of HCC, alcohol consumption,fatty liver, detectable levels of hepatitis B virus (HBV) DNA, and history of HBV infection without effective antiviral treatment. Multivariate logistic regression analysis indicated that age of 50 years or more (P =0.005, odds ratio [OR] =1.766), history of alcohol consumption (P =0.002, Or = 2.570), family history of HCC (P =0.014, Or = 2.268), fatty liver (P =0.023, Or = 3.390), and history of HBV infection without effective antiviral treatment (P < 0.001,Or = 5.389) were risk factors of HCC.The risk factors for development of HCC in cirrhotic patients with hepatitis B after achieving sustained virologic suppression (SVS) were family history of HBV infection (P =0.014, Or = 2.537), family history of HCC (P =0.037,Or = 3.339) and fatty liver (P =0.018, Or = 11.646).

CONCLUSIONRisk factors of HCC in cirrhotic patients with CHB include age,drinking history,family history of HCC, fatty liver, and ineffective antiviral treatment of CHB.Family history of HBV infection or HCC, and fatty liver disease, were significantly associated with HCC development after SVS in patients with hepatitis B-related cirrhosis.
