Objective To investigate the efficacy and side effects of new combination of high-dose methotrexate (MTX),cisplatin (DDP),pirarubicin (THP),and ifosfamide (IFO) in the treatment of extremity osteosarcoma patients.Methods A retrospective analysis was conducted for 125 osteosarcoma patients treated with the optimized neo-adjuvant chemotherapy combined with the four drugs mentioned above (MTX 200 mg/kg iv 6 h d1,CF 9 mg at one time,12 times; DDP 100 mg/m2,THP 30 mg iv,d8-10;IFO 3.0 g/m2 iv d16-18,mesna after IFO for 0,3,6,9 h).The efficacy and side effects of the therapeutic scheme were evaluated.Results The effective salvage rates of Ⅱ a and Ⅱb schemes were 36.4％ (8/22) and 79.6％ (82/103) with a statistical significance (P ＜ 0.05).The 2-year survival rate of schemes was 62.4％,and the survival time was(17.7 ± 8.3)months.The main side effects were myelo-suppression,nausea,and vomiting,etc.The incidence rate of myelo-suppression,nausea,and vomiting with grade Ⅲ-Ⅳ accounted for 71.2％,37.6％,and 13.6％,respectively.Conclusions The optimized neo-adjuvant therapy strategy based on high-dose MTX,DDP,THP,and IFO is effective in the treatment of osteosarcoma.

Chinese meteria medica (CMM) chain is a long-span chain covering agriculture which mainly depends on the forces of nature as well as high-tech CMM industry, CMM expertise industry and fast developing CMM circulation industry. Imbalance among the development of these industries produces bottlenecks and hinders the operation of the entire production chain. After analyzing the structure of Chinese meteria medica industrial chain from the perspective of national economy industry, three industry classifications and differentiation of factor intensity, we conclude that the complex structure of CMM industry chain is attributable to these three aspects. And the complexity is mainly shown at complex industry, varied product types, different coordination of various industrial sections and different technical growth speed of varied industry. We propose that structural complexity is the natural property of the chain, which is the main reason of industry sector development imbalance and bottleneck. Results of this research could provide theoretical analysis for future research on the coordination of industrial chain and the efficiency of resource allocation.

METHODS AMI model formatted by electricity to irritate the left ventricular branch of coronary artery of open-chest rabbit,and observation aspects including electrocardiogram(ECG),cardiac output and contractility,serumal enzymatic activities and biochemistry and pathology of lipid peroxide extent of myocardial infarction zone. RESULTS By urinate kinase(UK) combining with injection tanshin,abnormal changes of ECG, descending of cardiac contractiles and cardiac output,going up of serum cardiac damage enzyme(CPK-MB and LDH),and the malondialdehyde(MDA)of serum and myocardial infarction zone could be remarkably reduced or avoided during UK dissolving the thrombus to cure AMI rabbits. CONCLUSION Injection tanshin can clearly reduce or avoid lipid peroxidation damage during UK dissolving the thrombus to cure the acute myocardial infarction.

Objective To detect antibodies against chlamydial plasmid-encoded protein 3 (Pgp3),outer membrane complex protein B C-terminal peptide (OmcBc),CT841 protein and heat shock protein 60 (HSP60) in the sera of patients with urogenital Chlamydia trachomatis infection.Methods Recombinant plasmids encoding the aforementioned four proteins and an empty plasmid were transformed into Escherichia coli separately followed by 2-hour isopropyl-1-thio-β-galactopyranoside (IPTG) induction and cell lysis.The expressed proteins were purified with glutathione magnetic beads and then used to coat 96-well enzyme-linked immunosorbent assay (ELISA) plates precoated by glutathione.Serum samples were collected from 20 patients with and 20 clients without urogenital C.trachomatis infection attending the sexually transmitted disease (STD) clinic of Tianjin Medical University General Hospital.ELISA with the expressed protein-coated plates was adopted to detect antibodies against these proteins in the serum samples.Results Of the 20 serum samples from C.trachomatis-infected patients,14 (70％)had anti-Pgp3 antibody,9 (45％) anti-OmcBc antibody,8 (40％) anti-CT841 antibody,and 5 (25％) anti-HSP60 antibody.Meanwhile,no antibody was detected in any of the serum samples from uninfected clients except for one with anti-HSP60 antibody.Conclusions Of the four studied C.trachomatis proteins,Pgp3 appears to have the strongest antigenicity with the highest antibody-detection rate,while HSP60 exhibits the weakest antigenicity with the lowest antibody-detection rate.

Objective To investigate the changing of endothelial progenitor cells and nitric oxide in patients with pulmonary arterial hypertension secondary to chronic obstructive pulmonary disease.Method Mononuclear cells from 20 healthy persons (the control group, n = 20) , COPD patients without PAH (COPD non-PAH group, n =30) and patients with PAH secondary to COPD (COPD and PAH group, n=30) were investigated. Total mononuclear cells were isolated from peripheral blood by Ficoll density gradient centrifugation. EPC number and migration were assayed by colony forming unit-EPCs (CFU-EPCs) assay and modified Boyden chamber assay , respectively. EPC adhesion assay was performed by replanting those on fibronectin-coated dishes , then adherent cells were counted. The concentration of NO was measured with method of nitrate reductase.Result The numbers of CFU and migration, adhesion activity of circulating EPCs in COPD[ (21.9±3. 9)CFU-EPC] and PAH group[ (14. 2 ±3. 5)CFU-EPC] were significantly lower than that in non-COPD group and COPD non-PAH group [ ( 24.9 ±4.1) CFU-EPC ]. It was also observed that a strong negative correlation between the levels of PAH and the numbers of CFU and adhesion, migration activity of circulating EPCs. The NO level in the PAH group [ (43. 6 ±4. 8)ng/ml] was significantly lower than that in control group [ ( 67. 17±4.9 ) ng/ml ] ( P < 0.01). The NO level was positively correlated with number and migration ability of EPCs( r =0. 77,0.71, P <0.01) , but not correlated with adhesion ability.Conclusion The number of CFU and migratory, adhesive activity of EPC in patients withPAH secondary to COPD was significantly decreased. These changes may be associated with low level of plasma NO.
