Objective To analyze the relative factors of bone marrow suppression after chemotherapy with different-dose carboplatin and paclitaxel (TC) on the patients with ovarian cancer.Methods Sixty-two patients with ovarian cancer admitted in Beijing Obstetrics and Gynecology Hospital from January 2002 to December 2007, using TC regimen ,a total of 196 cycles of chemotherapy ,were divided into two groups by the doses of carboplatin [area under concentration-time curve(AUC) 4 -6 for low-dose,AUC >6 -7 for hight-dose, the carboplatin dose calculated with AUC] or by the doses of paclitaxel (135 -< 150 mg/m2 low-dose,150 - 175 mg/m2 hight-dose). After each TC cycle, the routine blood was test to determine the graduation of the marrow suppression, and then the correlation factors were analyzed with logistic regression. Results (1) The occurrence rate of bone marrow suppression:there were 159 cycles (81.1%) grade 0 - Ⅱ bone marrow suppression, while 37 cycles (18.9%) of grade Ⅲ - Ⅳ. (2) Factors related to bone marrow suppression:the results shown that there were not related to bone marrow suppression,which incluced cellular differentiation, tumor type, height, weight and paclitaxel dose(P>0.05). While,the different cycle, age, the later stages of tumor, serum creatinine concentration, endogenous creatinine clearance rate, AUC values were the relative factors of bone marrow suppression(P =0.000,0.000,0.018,0.033,0.001,0.000). Seven variables were conducted into the logistic regression and the results shown that the different cycles, the age, AUC grades were independent risk factors (P = 0.030,0.043,0.009).(3) When low-dose of paclitaxel was given, the occurrence of bone marrow suppression was related to the carboplatin dose AUC. The higher AUC values for carbopaltin were chosen, the higher of severe bone marrow suppression would happen. (4/14 vs 0,P=0.015). When the dose of high grade of paclitaxel was given, the occurrence of bone marrow suppression in cases with hight-dose carboplatin was statistically significant than that in cases treated with low-dose carboplatin [45.7%(16/35) vs 13.7% (17/124), P=0.000]. Conclusions The independent risk factors of myelosuppression after chemotherapy with TC regime on the patients with ovarian cancer including the cycles, age and AUC values. The carboplatin dose calculating with AUC is related to the occurrence of bone marrow suppression, the higher AUC values for carbopaltin would chosen,the higher of severe bone marrow suppression would be happen.

Objective To observe the efficacy and side effect of olanzapine combined with tropisetron, dexamethasone for the pre-vention of highly emetogenic chemotherapy-induced nausea and vomiting ( CINV) . Methods A total of 78 patients with highly emetogen-ic single day chemotherapy were randomly divided into two groups:trial group ( olanzapine combined with tropisetron, dexamethasone n=40) and control group (Tropisetron Combined with Dexamethasone n=38). The control of acute CINV, delayed CINV and adverse reac-tions were observed. Results The control rates of acute vomiting in trial group and control group were 87. 5% vs 81. 6%, 65. 0% vs 57. 9% in acute nausea, 75. 0% vs 52. 6% in delayed vomiting, 32. 5% vs 13. 2% in delayed nausea. The trial group was better than the control group in delayed vomiting and delayed nausea which there was difference between them (P < 0. 05). There was no statistical differ-ence between the two groups in the incidence of adverse reactions (P>0. 05). Conclusion Olanzapine combined with tropisetron, dexa-methasone for the prevention was significantly better than tropisetron combined with dexamethasone in the control of delayed CINV in pa-tients received highly emetogenic chemotherapy.

ObjectiveTo explore the ability of inhibition resistibility of multiple displacement amplification (MDA)in samples with inhibitors. To explain the application and value of MDA in forensic medicine by comparing with using magnetic beads methods(MBM)to purify sample.MethodsDifferent concentra-tions of hemoglobin and humid acid(HA)mixed with DNA samples and then divided the samples into MDA group, MBM group and control group.D3S1358locus was amplified and detected by polyacry-lamide gel electrophoresis detection system and AmpF?STR? IdentifilerTM Plus Kit-capillary electrophore-sis detection system.ResultsWhen hemoglobin concentrations exceed 1 ng/μL or HA concentrations ex-ceed 0.1 ng/μL, amplification products could not be obtained by single-locus system in control group. When hemoglobin concentration exceeds 100 ng/μL or HA concentrations exceed 1 ng/μL, the samples could not be amplified by MBM. Inhibitors in different concentrations were amplified successfully in MDA group without any influence from inhibitors.ConclusionMDA has the capability to remove the inhibi-tion of hemoglobin and HA, which is better than MBM and has a certain value in forensic practices.

The priming of puberty is date from the increase of the secretion of hypothalamic gonadotropin-releasing hormone (GnRH). Recently,Kisspeptins/ GPR54 signaling were found critical to promote the secretion of GnRH and the onset of puberty. KISSI expresses in special area of hypothalamus and is regulated by sex steroids in the estrous cycle.Kisspeptins transitive steroid feedback signals to GnRH cells, especially the positive feedback signal which causes preovulatory GnRH / LH secretion. Kisspeptins bind KISS1R in the hypothalamic GnRH neurons and evoke the release of GnRH and the onset of puberty.

Objective To develop a capture enzyme-linked immunosorbent assay (ELISA) for influenza A virus nonstructural protein NS1 using two anti-NS1 monoclonal antibodies(McAb) that map to distinct sites on the protein and to detect the NS1 in the culture supernatant and cell lysis supernatant of influenza virus. Methods Among the McAb against influenza A virus NS1, antibody pairs were analyzed to choose the optimal coating McAb and detecting McAb by determinating the detection sensitivity and specificity. Results The capture ELISA efficiently detected as little as 240 pg/ml of recombinant NS1 protein and exhibited no cross-reactivity for influenza B virus, parainfluenza virus NS1. Conclusion A sensitive and specific NS1-based capture ELISA for influenza A virus NS1 was successfully established, which could be an important tool for diagnosis of influenza A virus infection.

The United States is the first country that has introduced legislation designed to stimulate orphan drug research and development .In this paper , we analyze three major amendments of the Orphan Drug Act ( ODA) since 1983 and its incentive system .We then discuss the success of the ODA in encouraging orphan drug research and development and boosting the biopharmaceutical industry .Following that , we investigate the high price of orphan drugs caused by market exclusivity and drug repositioning .Finally, we draw experience from the ODA to make some suggestions on how orphan drug legislation can be devised in China with the aim of improving the health of rare -dis-ease patients and facilitating the development of Chinese biopharmaceutical industry .
