Elemene is a new anticancer drug isolated from a Chinese traditional medicine Curcuma aromatica. In previous work, we discovered that tumor cell vaccine (TCV) treated with oleum Curcuma aromatica or elemene could induce significant immunoprophylactic effect against a variety of aminal tumor strains and the method of preparation of elemene combo-TCV(EC-TCV) already got China's inventive patent. In this paper we further studied the active immunotherapeutic effect and the possible cellular/molecular mechanisms of EC-TCV immunization. The results were as follows:(1) EC-TCV immunization showed significant therapeutic effects (P<0.05) against murine Ca761 syngeneic mammary carcinoma (H-2k) and HCa-F allogeneic hepatic carcinoma (H-2-) models; (2) The spleen cells of Hca-F EC-TCV immunized mice displayed higher cytotoxicity and IL-12 level while the secretion of IL-10 was decreased (P<0.05); (3) Similar to heat shock, elemene(E), mitomycin C(MMC) and glutaraldehyde (G) could act alone as stressor, and induce significant changes of the expression of membrane heat shock proteins(HSP70 or/and HSP90) on L615 leukemia and HCa-F hepatoma cells and the EC-TCVs (E+MMC+G treated in combination) showed the highest level of membrane HSPs expression (P<0.05 or P<0.01 );(4) The HSP70-peptide complex isolated from HCa-F EC-TCV through ADP-agarose affinity chromatographic system could induce active immunoprotection against lethal dose challenge of HCa-F hepatic cancer cell but could not protect against the cross challenge of lethal dose of L615 leukemia. The results indicated that the immunoprotective effect of EC-TCV was in some extent tumor-specific, MHC-nonrestricted, and HSPs might play an important role in its molecular mechanisms.

OBJECTIVE:To establish the method for the determination of tigecycline (TGC) in human plasma. METHODS:After precipitated by acetonitrile,the plasma sample was determined by LC-MS/MS. Using d9-TGC as internal standard,Kromasil C18 column was used with mobile phase consisted of water (containing 0.05% TFA)-acetonitrile (gradient elution) at flow rate of 0.6 ml/min,column temperature of 40 ℃. The ion transitions were performed under ESI positive MRM model at m/z 586.3→513.2 and m/z 595.3→514.3 for TGC and internal standard,respectively. RESULTS:The linear range of TGC was 25-2 000 ng/ml (r=0.999 8),and lowest quantification limit was 25 ng/ml;intra-day and inter-day RSD was 3.15%-7.23%,and relative error was-4.53%-10.48%. Plasma sample kept stable after 3 times of freezing and thawing cycle,at room temperature for 24 h,in automat-ic sample injector for 24 h and freezing for 42 d (RSD<15%). Plasma concentration of TGC was 0-438.0 ng/ml in one patient with pan-drug resistant bacteria infection(0-12 h after administration). CONCLUSIONS:The developed method is accurate,sensi-tive and specific,and can be used for plasma concentration determination of TGC and pharmacokinetic study.

OBJECTIVETo observe the clinical efficacy of Xin'anning Nasal Drop (XAND) in treating coronary heart disease with unstable angina pectoris (CHD-UAP).
METHODSSixty patients with CHD-UAP were assigned, according to the randomizing number table, to two groups, the control group treated with conventional Western medicine, and the treated group treated with conventional Western medicine plus XAND. The clinical efficacy and the changes of S-T segment in resting EKG and total ischemia burden (TIB) in 24-h dynamic EKG were observed.
RESULTSThe clinical efficacy, including the effect of angina alleviation, its initiation, and the effect of TCM syndrome score reduction, were significantly superior in the treated group to those in the control group ( P<0.05 or P<0.01). The degree and extent of myocardial ischemia were significantly improved in both groups ( P<0.01), but the improvement in the treated group was better than that in the control group ( P<0.05). Moreover, it was worth mentioning that the immediate effect in the treated group was better than that in the control group, and the reduction of TIB, the improvement in heart rate and myocardial oxygen consumption (immediately after the first administration or by the end of the therapeutic course), and systolic blood pressure after treatment in the former were all superior to those in the latter, showing significant difference (P<0.05 or P<0.01).
CONCLUSIONXAND has a quick effect in alleviating angina in patients with CHD-UAP, and it is worthy of further studies and spreading in clinical practice. unstable angina pectoris, Xin'anning Nasal Drop, clinical study

Objective To investigate the epidemiology of viral infection in elderly patients to contract acute exacerbations of chronic obstructive pulmonary disease (AECOPD)in Minhang district of Shanghai from 2010 to 2012,and to study the relationships between viral infection and clinical features.Methods The elderly patients (age >70 year old)with AECOPD admitted from September 2010 to November 2012 were enrolled for study.The patients who couldn't complete lung function test were excluded.The pharyngeal swabs (PS)were taken from each patient within the first 24 h after admission.Nine respiratory viruses and their subtypes from pharyngeal swabs were detected by the nested multiplex polymerase chain reaction (PCR)method,including influenza virus A (FluA),2009 influenza A (H1N1 )virus (09FluH1 ), influenza virus B (FluB),respiratory syncytial virus A (RSVA)and B (RSVB),human coronavirus-229E (hCOV-229E),human coronavirus-NL63 (hCOV-NL63 ),human coronavirus-OC43 (hCOV-OC43 ), human coronavirus-HKU1 (hCOV-HKU1),human parainfluenza virus 1-4 (hPIV1-4),human adenovirus (hAdV),human boca virus (hBoV),human metapneumo-virus (hMPV)and human rhinovirus (hRV). According to the PCR results,all patients were divided into positive viral infection group and negative viral infection group.The relationships between viral infection and clinical features were analyzed.Results Sixty patients were eligible for study.Of them,14 patients were found to be positive for virus infection including a triple infected patient (FluB,hRV and hROV)and 46 patients were negative for virus infection.The viral pathogens detected in the positive viral group were:9 cases of hRV (15.00%),2 cases of hPIV (3.33%),2 cases of hCOV (3.33%),2 cases of FluB (3.33%)and 1 cases of RSV (1.67%).The mortality in the positive viral group was higher than that in the negative viral group.However,the other clinical characteristics between the two groups had no significant differences. Conclusions Human rhinovirus was the most common viral pathogen in elderly patients with AECOPD.Viral infection might be associated with the prognosis.However,the patients with viral infection are lack of specific clinical characteristics,therefore,the prompt diagnosis before careful study would be difficult.

OBJECTIVETo investigate genomic DNA imbalances in ependymomas (EDMs) and their correlations with the tumor histological types, grades, locations, patients' gender and age.
METHODSChromosomal gains and losses in 16 cases of EDM were analyzed using comparative genomic hybridization.
RESULTSChromosomal regional gain and loss were found in 15 and 13 of 16 EDM cases respectively including totally 24 regional gains and 19 regional losses in all the tumors studied. Both regional gains and losses were mostly seen in myxopapillary EDMs (MPE, WHO grade I), more commonly seen in cellular EDMs (CE, WHO grade II) and tanycytic EDMs (TE, WHO grade II) than in anaplastic EDMs (AE, WHO grade III). Some of the regional gains and losses appeared only in one subtype of MPE, CE, TE and AE cases resulting in development of specific imbalance profiles of certain subtype in these cases. MPE, CE and TE often had +7. Chromosomal +5 occurred only in MPE and CE, and -22q was only seen in CE and TE. AE frequently had +1q, but none had +5, +7, -4q, -19q and -22q. The frequencies of any regional gain or loss were not affected by patients' genders (P > 0.05). Chromosomal +1q and +7p happened predominantly in intracranial EDMs with an averagely onset age of CONCLUSIONSThe frequencies of chromosomal imbalances in EDMs decrease as the tumor grade increases. Characteristic chromosomal imbalances in each subtype may play an important role in determination of histological phenotypes and tumor grades. Chromosomal +1q, +5, +7p, +7, -4q, -19q and -22q are alterations which may dictate the biological behaviors of these tumors and the patients' prognosis.
