BACKGROUND:Cancer stem cel s have self-renewal ability and can differentiate into new tumors. Cancer stem cel s are the source of tumor formation and recurrence, and they can make tumors insensitive to radiotherapy and chemotherapy.
OBJECTIVE:To explore the effect of paclitaxel plus cisplatin on the proliferation and apoptosis of nasopharyngeal cancer stem cel s (NPCSCs) and involved signal pathways.
METHODS:NPCSCs were sorted by immunomagneticbeads and were treated with paclitaxel, cisplatin or their combination. The expression of caspase-3, activated caspase-3 and Bcl-2, which are related to apoptosis, was determined by western blot. The expression ofβ-catenin and its downstream proto-oncogene, c-myc, was also determined by western blot. The activity of the Wnt/β-catenin pathway was inhibited by knocking downβ-catenin expression orβ-catenin inhibitor XAV939. Proliferation and apoptosis of NPCSCs were detected by MTT and flow cytometry, respectively.
RESULTS AND CONCLUSION:Either paclitaxel or cisplatin could inhibit proliferation and induce apoptosis of NPCSCs. The expression of apoptosis marker, activated caspase-3, was increased and the expression of the inhibitor of apoptosis, Bcl-2, was declined. Combined use of paclitaxel and cisplatin had synergistic effect when used together. Either paclitaxel or cisplatin could inhibit the expression ofβ-catenin and c-myc, suppressed the proliferation and induced the apoptosis of NPCSCs by inhibiting the activity of Wnt/β-catenin pathway. These results indicate that the combined use of paclitaxel and cisplatin may inhibit the proliferation of NPCSCs and promote apoptosis via the Wnt/β-catenin pathway.

The noninvasive measurement of liver stiffness (LS) was evaluated by transient elastography (FibroScan) and the possible influencing factors from the patients' clinical situations including age, gender, liver inflammation represented by alanine transaminase (ALT) and total billirubin (TBIL) level, HBV replication (HBV DNA loads), portal vein pressure (portal vessel diameter, PVD), splenic thickness (SPT) and body mass index (BMI) were analyzed in patients with chronic hepatitis B (CHB). A total of 466 patients including 31 patients with acute-on-chronic liver failure (ACLF), and 435 patients with chronic hepatitis B (CHB) among which 82 patients were diagnosed with liver cirrhosis (LC) by clinical manifestations and liver B-type ultrasonic inspection were enrolled at Tongji Hospital from April to December 2009. LS was measured by a FibroScan device (EchoSens, France). Simultaneously, ALT and TBIL levels, HBV DNA loads, PVD, SPT and BMI in all patients were also tested. Forty-one healthy volunteers served as controls. The values of LS were correlated positively with ages of CHB patients and significantly higher in males than in females. In patients with BMI>28 kg/m(2) (obesity) and abnormal levels of ALT and TBIL, LS values were significantly increased as compared with those having normal levels of ALT and TBIL. The patients with ACLF had the highest LS value. Furthermore, LS values in the patients with LC were significantly higher than those in patients without LC. It is concluded that noninvasive measurement of liver fibrosis by FibroScan provides an alternative method to evaluate liver fibrosis of patients with CHB. In order to properly illustrate the stiffness value taken by transient elastography, patients' gender should be taken into consideration and it is also suggested to avoid possible influencing factors including liver inflammation (high levels of ALT and TBIL) and obesity (high BMI).

ObjectiveTo explore the clinical diagnosis and surgical treatment of primary retroperitonealneurilemoma(schwannoma). MethodsClinicaldataof 47patientsof primary retroperitoneal schwannoma admitted and surgically treated from January 1995 to December 2009 were retrospectivelly reviewed.ResultsAs diagnosed by pathology there were 36 cases of Benign schwannoma,with a median age at onset of 41years, among those 11 patients were symptomatic, and 25 were asymptomatic. There were 11 malignant 11 cases, the median age was 38 years, among those 6 patients were symptomatic, and 5 were asymptomatic. The positive diagnostic rate of preoperative CT and MRI were 36. 2% ( 17/47 ) and 58. 3% ( 7/12 ) respectively. Immunohistochemically positive rates of S-100 were 100% and 81.8%(9/11) in benign and malignant group respectively.All cases underwent surgical treatment. Surgical resection rates for benign and malignant groups were 100% and 90. 9%(10/11)respectively. There was no perioperative death, Overall 5-year survival rates were 100% and 45.5% for benign and malignant tumors groups respectively. In benign group 2 cases recurred, in malignant group 4 cases recurred, and 3 had distant metastasis.ConclusionsPrimary retroperitoneal schwannomas are less common. It is difficult to make an accurate preoperative diagnosis. Surgery is the most effective therapy.Prognosis is good for benign and poor for malignant retroperitoneal neurilemomas.
