Objective Previous study showed that interval debulking surgery (IDS) may improve the survival of patients with advanced epithelial ovarian cancer (EOC).The precise significance of IDS needs to be evaluated.Methods Totally 136 consecutive patients with stage Ⅲ c or Ⅳ EOC (including primary peritoneal carcinoma and primary fallopian tube carcinoma ) who completed primary debulking surgery (PDS) and platinum-based chemotherapy were enrolled from January 2000 to December 2009 in a retrospective cohort study.The study group was divided into three groups:65 cases underwent optimal PDS (Group A ),41 cases received chemotherapy alone after suboptimal PDS (Group B ),and 30 patients underwent IDS after suboptimal PDS (Group C).All patients received six to eight courses of platinum-based combination chemotherapy (paclitaxel plus carboplatin/cisplatin,cyclophosphamide plus epirubicin and cisplatin).Patients' clinical characteristics,perioperative situation and prognosis were compared. Results Sixty-five cases (47.8％,65/136) from 136 patients achieved optimal PDS.For Group C,77％ (23/30)patients obtained optimal debulking surgery after IDS.Intraoperative injury rates were similar between Group B and Group C ( P ＞ 0.05 ).Mild perioperative complications rate was also similar ( P ＞0.05 ).Median progression-free survival (PFS) of Group A was 26 months.Median overall survival (OS) of Group B and Group C were 3l months and 40 months,respectively (P =0.254).Median PFS of Group B and Group C were 13 months and 24 months,respectively (P =0.289).Although when it came to 20 months after PDS,patients who underwent IDS had a significantly lower progressive disease (PD) rate (Group B 33％ versus Group C 61％,P =0.046 ),it still showed that there was no significant difference in either OS or PFS of these two groups.Those patients in Group C who obtained no visible residual got similar PFS (27 months) comparing to Group A (26 months,P =0.730),but OS was still shorter (P =0.010).Conclusions For advanced EOC patients,IDS has little effect on improving survival.While it is safe and acceptable,also may prolong PFS in those patients who got no visible residual after IDS.The results suggest that IDS might be used as an alternative treatment for advanced EOC patients who cannot obtain optimal PDS in certain local hospitals.

Objective To analyze the prognostic factors associated with three-year survival outcome in patients with serous ovarian adenocarcinoma by classification tree.Methods Retrospectively we analyzed 81 cases with serous ovarian adenocarcinoma who had 3-year clinical outcomes and were hospitalized in People's Hospital from Jan 1991 to Dec 2003 by classification and regression trees(CART)software.Establish the classification tree.Results Among the factors that were associated with the 3-year survival rate,age was the most important factor,other factors in turn were International Federation of Gynecology and Obstetrics(FIGO)stage,lymphoid metastasis,residual size after operation,chemotherapy and pathologic grade.By substitution variable analysis,it was demonstrated that there was cross interaction between age and residual size as well as age and chemotherapy.Conclusion Age,FIGO stage,lymphoid metastasis,residual size after operation,chemotherapy and pathologic grade are important prognostic factors related with three-year survival probability of serous ovarian adenocarcinoma patients.

Objective To evaluate the efficacy and tolerability of the combination of oxaliplatin,ifosfamide and epirubicin(IAP)in treatment of recurrent or platinum-resistant ovarian cancer patients.Methods A total of 25 patients received the combined chemotherapy of ifosfamide(3-4 g/m2),epirubicin(50-60 mg/m2)and oxaliplatin(130 mg/m2).The cycles were repeated every 21 days.The efficacy and toxicity were evaluated in 21 patients who received more than 2 cycles of IAP chemotherapy.Results The overall response rate was 71%,with a complete response in 10(48%),partial response in 5(24%),stable disease in one(5%),and disease progression in 5(24%).The median progression-free and overall survival time were 11(1 to 33)months and 31(1 to 71)months.While overall response rate was 60%in 10 patients with primary platinum resistant,and 88%in 8 patients with secondary platinumresistant.Grade Ⅲ-Ⅳ myelosuppression rate wss 30%.The most common non-hematologic toxicity was perineurotoxicity(38%).Conclusions The combination of oxaliplatin,ifasfamide and epirubicin appears to be effective for recurrent or platinum-resistant ovarian cancer patients as salvage chemotherapy and the toxicity is also tolerable.However,it needs to be evaluated by multiple clinical trials.

OBJECTIVETo explore the relationship between the genetic polymorphism of fibronectin (FN) (4 genetic locus) and pneumoconiosis.

METHODS128 male I-period pneumoconiosis were selected as cases who were examined with radiography and diagnosed by the Pneumoconiosis Diagnosis Expert Panel, based on the Chinese National Diagnosis Criteria of Pneumoconiosis (GBZ 70 - 2002). According to 1:1 paired matching method, 128 dust exposure workers were selected as control who were exposed to same dust as cases. The difference of age and cumulative length of service between case and control was not over five years and two years, respectively. 5 ml peripheral venous blood was drawn and anticoagulated with 2% EDTA. The polymorphisms of FN (MspI, TaqIb, HindIII, HaeIIIb) were detected, using the method of polymerase chain restriction fragment length polymorphism (PCR-RFLP) techniques and PCR.

RESULTSThe frequencies of FN Msp I (CC) in cases and control groups were 10.9% and 3.9%, respectively. The difference was significant (P < 0.05). The frequencies of FN (MspI) C allele were 41.8% and 31.2% in case and control, and the difference between cases and controls was significant (P < 0.05). The frequencies of FN HaeIIIb (AA) genotype in cases (24.2%) was higher than that in control groups (17.9%), OR = 5.0 (95% CI: 4.840 approximately 24.210). The frequencies of FN (HaeIIIb) A allele were 51.9% and 42.2% in case and control, and the difference was significant (P < 0.05). The difference of TaqIb and HindIII genotype between cases and controls were not significant (P > 0.05).

CONCLUSIONThe risk of suffering from pneumoconiosis increases in workers carrying FN (MspICC or HaeIIIb AA) genotype after exposure to dust. Workers both carrying FN (HaeIIIb AA) and (MspICC) genotypes are more susceptible to pneumoconiosis. The relationship between genetic polymorphism of FN (TaqIIb, HindIII) and pneumoconiosis has not been found.

This study was aimed to investigate the effect of baicalin on proliferation and apoptosis of HL-60 cells and its mechanism. Cell proliferation was assayed by using Cell Counting Kit-8. The morphological changes of HL-60 cells were examined by light microscopy and nucleolus morphological changes were observed by fluorescent microscopy after Hoechst 33342 staining. The early cell apoptosis was detected by using flow cytometry with Annexin V-FITC/PI double staining. The expression of caspase-3, caspase-9, Bcl-2 and Bax mRNA was detected by RT-PCR and Western blot assay was carried out to examine Bax, Bcl-2, caspase-8 and cleaved caspase-3 expression. The results showed that Baicalin inhibited the proliferation of HL-60 cells in a time- and concentration-dependent manner. HL-60 cells exhibited typical morphological features (for example, cell shrinkage, membrane blebbing and formation of apoptotic bodies). Cell apoptosis in early stage could be detected, the expression of caspase-3, caspase-9 and Bax mRNA was obviously up-regulated, while the Bcl-2 expression down-regulated, and accordingly Bcl-2/Bax ratio decreased. Such results were consistent with the expression of these proteins. In addition, the expression of cleaved caspase-8 protein was induced significantly after treated with baicalin. It is concluded that baicalin can significantly inhibit the proliferation of HL-60 cells and induce the apoptosis of HL-60 cells, which may occur through decreasing Bcl-2/Bax ratio by intrinsic pathway and through extrinsic pathway. It suggests that baicalin may be a promising drug for the therapy of acute myeloid leukemia.

BACKGROUNDDaxx has been identified as a nuclear protein that involves in apoptosis and transcriptional repression. Daxx co-localizes with the promyelocytic leukemia (PML) protein and regulates transcription. Human Daxx (hDaxx) is a protein that functions as a transcriptional regulation through its interaction with some DNA-associated proteins. The aim of this study was to explore the transcriptional regulatory effect of hDaxx interacting with adenovirus (Ad) 12 E1B (Ad12E1B) 55-kDa oncoprotein.

METHODSThe co-localization of hDaxx-Ad12E1B or hDaxx-PML protein in the nucleus was observed under a confocal microscope. Interaction of hDaxx and Ad12E1B was analyzed by yeast two-hybrid assay. Direct binding of hDaxx and Ad12E1B was analyzed using coimmunoprecipitation and Western blot in vivo and in vitro. The activity of a luciferase reporter gene, which was regulated by an hDaxx modulated thymidine kinase (TK) promoter, was detected in an automat luminometer.

RESULTSAd12E1B, which co-localized with hDaxx in the nuclei of G401-CC3 cells, disrupted the co-localization of hDaxx and PML in the PML oncogenic domains (PODs). hDaxx bound directly to Ad12E1B in vivo and in vitro. hDaxx interacted with Ad12E1B along its full length. Ad12E1B enhanced transcriptional repression activity of hDaxx.

CONCLUSIONAd12E1B disrupts the co-localization of hDaxx with PML in PODs and enhances transcriptional repression activity of hDaxx.

Objective To investigate whether the change of serum tumor markers profile after chemotherapy in epithelial ovarian carcinoma and evaluate the clinical significance. Methods The levels of CA125, CA19-9 and CP2 before and after initial surgery, during primary chemotherapy and follow-up were serially measured and analyzed retrospectively in 28 cases of recurrent epithelial ovarian carcinoma patients and 20 cases of primary chemo-resistant ovarian carcinoma patients from Jan 1999 to July 2007. According to whether the change of serum tumor markers profile, all the patients were divided into two groups: marker changed-group and marker un-changed group. The average follow up period was 25 months. Results (1) The changes of tumor marker profile were included the number and (or) types of markers, which included 13 cases (46%, 13/28) of the recurred cases and 9 cases (45%, 9/20) of the primary chemo-resistant cases. (2) For recurrent ovarian carcinoma changed tumor marker profile, the highest pathology type was serous histological type (77%, 10/13 ), while was mucinous histological type (4/9) for primary chemo-resistant patients. (3) For recurred patients, the median progression-free survival (PFS) and median overall survival (OS) in marker changed-group (22.2 and 60.0 months) were significantly longer than that in marker un-changed group (17.4, 46.0 months; P<0.05). For primary chemo-resistant ovarian carcinoma patients, median OS in marker changed-group (15.9 months) was significantly shorter than that in marker un-changed group (25.0 months; P<0.05 ). Conclusion The profile of serum tumor makers in epithelial ovarian carcinoma may be changed after chemotherapy, which should be concomitantly determinate different serum tumor markers for monitoring the response to chemotherapy and follow-up of patients.
