Objective:To analyze the relationship between hepatitis B virus(HBV)gene mutation at 1896 in precore region with genotype and replication of HBV and the liver function of patients.Methods:HBV precore 1896 site mutation,the genotype of HBV and serum content of HBV DNA were determined by PCR in 60 patients positive of HBV DNA.Chemiluminescence miacropaticle immunoassay(CMIA)was used for detection of serum HBeAg and HBeAb.Liver function parameters were ob- tained by routine biochemistry method.Results:The alanine aminotransferase(ALT)level in HBV with 1896 site mutation was significantly higher than that in the wildtype virus.Site mutation at 1896 had no correlation with HBeAg,HBV genotype and HBV DNA content.HBV DNA content in patient with genotype C was significantly higher than that with genotype B(P

Background and purpose:Although there is still no standard ifrst line chemotherapy regimen for metastatic gastric cancer (MGC), the doublet and triplet regimens containing platinum and lfuorouracil were most popular worldwidely. The ECF regimen is the classical and one of the most popular treatment choices in this setting, while the marrow suppression, the renal toxicity and poor compliance inhibits its usage. In order to improve its efifcacy and tolerability, this study conducted 2 phaseⅡ trials by modified ECF regimen, the EOF5 regimen (substituting cisplatin with oxaliplatin, shortening the continuous infusion period to 120 h), to treat patients with MGC since 2004. This paper reported the comprehensive results of the 2 studies.Methods:All the patients who enrolled in our previous2 phaseⅡ trials and received EOF5 as ifrst line treatment entered this study. Each patient received the treatment of epirubicin 50 mg/m2 iv d1, oxaliplatin 130 mg/m2 iv gtt d1 and 5-FU 375-425 mg/m2·d-1 civ 120 h, and repeated every 3 weeks. Efifcacy was analyzed every 6 weeks.Results:A total number of 178 patients (all were metastatic patients but 2 advanced patients with unresectable lesions) were included into this study. One hundred and seventy patients were evaluable, and 7 patients (3.9%) achieved complete response (CR), 76 patients (42.7%) achieved partial response (PR), 46.6% patients achieved overall response rate (ORR, CR+PR), and the cases of stable disease (SD) and progressive disease (PD) were 69 (38.8%) and 18 (10.1%), respectively. The median progress free survival (PFS) and overall survival (OS) were 6.0 months (95%CI: 5.2-6.8) and 12.6 months (95%CI: 8.9-16.3), 1-year and 2-year survival rate were 50.9% and 28.0%, respectively. Grade 3, 4 toxicity including: leucopenia (23.0), neutropenia (38.8%), anemia (6.5%), thrombocytopenia (23.5%), nausea/vomiting (14.1%), and peripheral neuropathy toxicity (1.2%). Among 75 patients who received second line treatment, the median survival from second line treatment was 8.0 months (95%CI: 4.8-11.2).Conclusion:EOF5 regimen is a highly effective regimen with moderate and manageable toxicity, and it providesa suitable alternative for the ifrst-line treatment of MGC.

OBJECTIVETo observe the incidence, causes and deviation angle of axial offset in patients with fracture ununited treated by Ilizarov bone transport technology.

METHODSFrom January 2007 to December 2012, 10 patients with fracture ununited were treated by Ilizarov bone transport including 8 males and 2 females with an average age of (30.3 ± 10.6) years old ranging from 18 to 49 years old. The segment of bone defect involved upper tibial in 2 cases, medial tibia in 2 cases, lower tibial in 5 cases, upper femoral in 1 case. For Paley type of bone defect, 6 cases were type B1, 4 cases were B3. The incidence and deviation angle of axial offset after Ilizarov bone transport technology were observed and evaluated on bone result by Paley assessment.

RESULTSAll patients were followed up from 19 to 32 months with an average of (22.0 ± 5.6) months. Three cases were natural healed at fracture ends, the other 7 cases were healed after bone graft. The time of external fixator was 16 to 28 months. At the last follow-up, there were 3 cases occurred coronal angulation of angle 5° to 11° with an average of (8.7 ± 3.2). Sagittal angulation was in 4 cases, angle 6° to 9° with an average of (8.5 ± 2.1)°. There were 4 cases occurred axial offset. In the last follow-up, according to Paley evaluation criteria, osseous results were excellent in 7 cases, good in 3 cases; functional results were excellent in 6 cases, good in 4 cases.

CONCLUSIONAxial deviation after the Ilizarov bone transport treatment is relatively common, which will result in delayed healing of bone and poor limb alignment. In order to improve the bone healing, corresponding measurements should be taken to avoid or reduce the incidence of axial deviation during and after the operation.

BACKGROUNDP-glycoprotein (P-gp) encoded by ATP-binding cassette sub-family B member 1 (ABCB1) gene is a kind of ATP-dependent drug transporter, which plays important roles in multidrug resistance (MDR) of human cancers, such as osteosarcoma. Curcumin is a natural phenolic coloring compound originating from the rhizomes of Curcuma longa, which is proved to possess antitumor biological activities including reversion of MDR. However, the effect and molecular mechanisms of curcumin to osteosarcoma MDR remain unclear.

METHODSWe established a human osteosarcoma drug-resistant cell line MNNG/HOS/MTX by pulse exposure to methotrexate (MTX) and verified that the new cell lines were cross-resistant to other anticancer agents. Then, according to the cytotoxicity assay, we reversed MDR of MNNG/HOS/MTX by 30 µmol/L curcumin, and detected the mechanisms of curcumin reversing MDR through Real-time PCR, Western blotting assay, and Rhodamine123 (Rh123) transport test. Finally, we evaluated the effect of curcumin reversing MDR in vivo by MNNG/HOS/MTX cells xenograft-nude mice model.

RESULTSMNNG/HOS/MTX was proved to be a human osteosarcoma MDR cell line. MTT tumor chemosensitivity test indicates that 30 µmol/L curcumin attenuates the half maximal inhibitory concentration (IC50) and resistance index (RI) to MTX, diamminedichloroplatinum (DDP), adriamycin (ADM), ifosfamide (IFO), and epirubicin (EPI) in MNNG/HOS/MTX cells (P < 0.05). Real-time PCR and Western blotting assays demonstrated that curcumin down-regulated P-gp expression of MNNG/HOS/MTX cells. Rh123 transport test showed that curcumin inhibited the transport function of P-gp in vitro. In vivo studies showed that curcumin displayed the features of sensitizing antitumor drugs and inhibiting the proliferation, invasion, and metastasis of osteosarcoma MDR cells.

CONCLUSIONDown-regulation of P-gp and inhibition of the function of P-gp efflux pump may contribute to MDR reversion induced by curcumin in vitro and in vivo.

The paper is to report the development of a high-performance liquid chromatographic/tandem mass spectrometry (HPLC-MS/MS) method for the determination of icaritin (ICT) in rat plasma. After precipitated with acetonitrile from the plasma, ICT was isolated chromatographically on a Dikma C18 column. The mobile phase consisted of acetonitrile-water-acetic acid (72 : 28 : 1.5, v/v/v). Electrospray ionization (ESI) source was applied and operated in the positive ion mode. Multiple reaction monitoring (MRM) mode with the transitions of m/z 387 --> m/z 313 and m/z 331 --> m/z 315 were used to quantify ICT and the internal standard, respectively. The linear calibration curve was obtained in the concentration range of 2.5-1,000 ng x mL(-1). The lower limit of quantification was 2.5 ng x mL(-1). The inter- and intra-day precision (RSD) were less than 9.63%, and the accuracy (relative error) was within +/-7.42%. The method was proved to be suitable for the pharmacokinetics of ICT, which offers advantages of high sensitivity and selectivity.

OBJECTIVE: To investigate and analyze the occurrence of 64,101 perinatal birth defects from 2000 to 2004, to determine the tendency of the incidence rate of birth defects and perinatal mortality, and to explore feasible and effective intervention strategy. METHODS: We investigated 64,101 perinatal infants who were born in 13 hospitals in Changsha from January 2000 to December 2004. The incidence rate of all birth defects, mortality of perinatal infants, the incidence rate of various kinds of birth defects, and the component rate of birth defects were analyzed. RESULTS: Altogether 1,050 neonate birth defects were found, with the incidence rate of 1.638%. The incidence rate of birth defects was increasing year-by-year in 2000 compared with that in 2002, 2003 and 2004, with significant differences (all P values<0.05): the incidence rate of birth defects in 2001 compared with that in 2002, 2003 and 2004, also with significant differences (P<0.05). Eight hundred seventy nine perinatal infants died, and the mortality was 1.371%. The mortality perinatal of infants increased in 2001 compared with that in 2002 and in 2003, with significant differences (P<0.05). The top 5 birth defects with the highest incidence were congenital heart disease, polydactly, auricle malformation, cheiloschisis, and palatoschisis, congenital hydrocephal in turn. The incidences of congenital heart disease and hydrocephal increased significantly. One hundred seventy seven fetuses were performed induced labor because of fetal defects from 2003. CONCLUSION We must pay attention to the increasing tendency of birth defect incidence and perinatal mortality. Strengthening environmental protection and antenatal care can decrease the birth defect incidence. Performing antenatal examination and neonatal screening regularly can discover the birth defects in time. When severe birth defects occur, the induced labor should be performed.
