Survivin is a member of the IAP family, which has been shown to localize to various components of the mitotic apparatus. Survivin is not only an apoptosis inhibitor, but a mitotic regulator as well. Survivin is Absolutely undetectable in normal tissues, but over-expressed in all the most common human cancers. Survivin is considered as an important target in cancer treatment, and the research on its molecular antagonists has gained encouraging achievements.

A female patient with a dark red mass in the of preauricular area for over 3 months was hospitalized. Enhanced CT scan and ultrasonography showed that the mass had clear boundaries and was rich in blood supply. The patient was misdiagnosed as preauricular hemangioma, then the mass was removed as a benign tumor and found irrelevant to parot, SMA(+), Vim(+), S-100(+), indicating myoepithelial carcinoma. So a radical excision was performed to get negative incised margin. The patient didn't undergo postoperative chemotherapy but demonstrated no evidence of recurrence over a 12-month follow-up.

Objective To study the therapeutic effect of pingyangmycin local injection under suspension microlaryngoscopy for treatment of laryngopharyngeal and laryngeal hemangioma. Methods The total of 44 cases of patients with laryngopharyngeal or laryngeal hemangioma were randomly divided into the experimental group ( n=22 ) and the control group (n=22). They were treated with bleomycin 5 mg or pingyangmycin 4-8 mg injection under suspension microlaryngoscopy in the hemangioma, respectively. If the treatments were not curative, repeated one more times in intermittent 15 d, but not more than 3 times. Therapeutic effect and adverse effect were recorded and analyzed. Results The total effective rate (95. 4%)in the experimental group was significantly better than that (59. 1%) in the control group (P<0. 05),and side reaction in two groups showed no significant variation. Conclusion Pingyangmycin local injection for treating laryngopharyngeal and laryngeal hemangioma is effective, less adverse reaction.

Objective To evaluate the in vitro differentiation of human amniotic epithelial cells (hAECs ) into hepatocyte-like cells. Methods Combined approach of dexamethasone, HGF, IGF and other cytokines were used to induce the differentiation of hAECs into hepatocyte-like cells. The induction lasted 2 weeks. During the induction, the expression of albumin ALB, CYP1A1, CYP1A2, IGFR, c-met and key functional genes related to liver cells as well as transcription factors HNF3, HNF4 and C/EBPa were monitored by RT-PCR. Time dependent changes of the surface marker colony ALB, AFP and CK18 were analyzed by cell flow cytometry. Results After the 2 week induction, the expressions of liver hepatocyte-like cell functional genes such as albumin, CYP1A1, CYP1A2, c-met, and transcription factors such as HNF3, HNF4, C/EBPa and HNF1 were observed. Six days after the induction, hAECs mainly were stained AFP+, and the positive rate was (15.1±2.1)%. While 10 days after the induction, part of the hAECs showed AFP+/ALB+ (6.5±1.4)%; and on 14th day, hAECs only showed ALB+, and the rate was (13.9±2.3)%. ALB+ cell increase indicated a gradual functional maturation from the hAECs to hepatocyte-like cells. Similaritly, the number of CK18+ cells in the whole population was also increased: On 10th day, the rate was (16.1±1.2)%; on 14th day, that was (21.3±4.6)%, which proved the above hypothesis of the trandifferentiation. By extending the induction time, the expression of functional genes increased gradually, and a maturing process of hAECs was detected by cell surface markers. Conclusion The differentiation of hAECs induced in vitro has the characteristics of hepatocyte-like cells.

BACKGROUND:There are many preliminary studies on the survival, metaptosis, and correlation characteristics of human amniotic epithelial cel s after transplanted into the animals, but there are no reports on the quantitative analysis of the transplantation effect. OBJECTIVE:To make quantitative analysis on serum biochemical function of liver and the expression of human albumin in mice received passaged human amniotic epithelial cel s transplantation in spleen. METHODS:Forty nude mice were randomly divided into four groups (n=10 in each group):hepatectomy+cel transplantation 2 weeks group, hepatectomy+cel transplantation 4 weeks group, hepatectomy+normal saline group (treated with partial hepatectomy) and hepatectomy+cel transplantation group (transplanted with 0.2 mL passaged human amniotic epithelial cel s with 5×106 under spleen, and the blood were col ected at 2 and 4 weeks after transplantation). The mice in the hepatectomy+normal saline group were treated with splenic injection of 0.2 mL normal saline;the cel transplantation group did not receive hepatectomy, and transplanted with 0.2 mL passaged human amniotic epithelial cel s with 5×106 under spleen. The histological and morphological changes of the liver and spleen in each group as wel as the expressions of serum alanine aminotransferase, aspartate aminotransferase and human serum albumin in each group were detected, and the quantitative analysis of human serum albumin expression was performed. RESULTS AND CONCLUSION: There was no obvious morphological change after human amniotic epithelial cel s transplanted into the acute liver injury mice for 4 weeks, but specific cel s could be detected by histological method. The serum levels of alanine aminotransferase, aspartate aminotransferase and human serum albumin were improved obviously, and the human albumin could be detected in serum, the level of human albumin at 4 weeks after transplantation was significantly increased than 2 weeks after transplantation. Human amniotic epithelial cel s can survive for more than 4 weeks after transplanted into the liver injury mice, and can stil express partial characteristics and functions of hepatocyte-like cel s, improve the liver function, thus treating acute liver injury.
