Traditional Chinese medicine is the few field of owing independent intellectual property in China, the implement of intellectual property strategy is important for the long-term development of traditional Chinese medicine enterprises. At present, traditional Chinese medicine enterprises still remain many problems in intellectual property protection, such as weak awareness of intellectual property protection, lack of intellectual property protection professional personnel, inadequate investment in R & D and low innovation level. These problems caused huge losses in practice to traditional Chinese medicine enterprises. After analyzing the status of intellectual property protection of traditional Chinese medicine enterprises, we put up with some concrete measures of intellectual property protection of traditional Chinese medicine considering the reality of these enterprises.

We analyzed and sorted the policies and regulations of traditional medical management in international markets which also affecting traditional Chinese medicine and summaried current situation of barriers of policy and regulation of Ttraditional Chinese medicine.After thoroughly analyzing the reasons of barriers of policy and regulation of traditional Chinese medicine,we found that the reasons lied in culture difference between China and western countries,quality of traditional Chinese medicine,low level of R&D and manufacturing,incomplete domestic laws and regulations of traditional Chinese medicine,lack of anti-technical barriers to trade service system.In the end of this paper,we came up with some countermeasures of barriers of policy and regulation when traditional Chinese medicine accessing international markets.

Australia is a country with strict drug administration, which is hard for its market access. Chinese Medicine Registration Act 2000 enacted by Victoria State of Australia established the legal status of traditional Chinese medicine in Victoria State, which made Australia the first one of western nations to legislate traditional Chinese medicine. We should take advantage of this opportunity to give in-depth analysis of laws and regulations on traditional Chinese medicine in Australia to push on traditional Chinese medicine to enter the Australia market. By analyzing the regulations of traditional Chinese medicine in Australia market, we put forward the following strategies on traditional Chinese medicine accessing Australia market: first, we should strengthen cooperation of Chinese and Australian governments; secondly, we should focus on analysis of regulations of drugs of Australia, thirdly, we should establish technical standard of herbal drugs in conformity with international standard; finally, we should strengthen traditional Chinese medicine culture exchange.

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.

AIM: To observe the effect of aminoguanidine (AG) on hemodynamics and lung capillary permeability in acute lung injury (ALI) in rabbits. METHODS: 24 rabbits were equally divided into four groups: saline group, endotoxin group, AG group and AG plus endotoxin group. In AG plus endotoxin group, endotoxin was injected to animals to make an ALI model, 25mg/kg AG was injected following that and let this sustain 3 hours. Meanwhile, mean arterial pressure (MAP), mean pulmonary arterial pressures (MPAP) and blood gas analyses were observed during this period. At the end of the experiment, broncho-alveolus lavage was performed, pathologic samples were treated routinely and lung wet weight/dry weight ratio was calculated. RESULTS: After endotoxin injection, MAP and arterial oxygen pressure (PaO 2) decreased, and MPAP increased significantly. The injection of AG had little effect on MAP, but AG could markedly decrease MPAP and increase PaO 2. Cell count in broncho-alveolus lavage fluid (BALF) was less in AG plus endotoxin group than in endotoxin group. Although AG did not affect total protein in BALF, low molecular weight proteins decreased in AG plus endotoxin group by the assay of electrophoresis. Tissue wet weight/dry weight ratio also decreased in this group. Pathologic study showed that there were fewer inflammatory cells and less lung edema in AG plus endotoxin group. CONCLUSION: AG could improve hemodynamics status and attenuate acute lung injury induced by endotoxin in rabbits. [

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.

In this study levels of copper-zinc suproxide dismutase (SOD-1) in HL-60 cells and mononucleocytes (MNC) of patients with leukemia were determined by radioimmunoassay and were correlated to DNA content and percentage of S phase of leukemic cells. The results showed that the levels of SOD-1 in HL-60 cells and MNC of AML, CML and B-ALL were higher than those in normal MNC (P

Oridonin is ent-kaurane diterpenoid and is one of the efficacious component of Rabdosia Rubesecens ( Hemel. ) Hara in Henan province. In this experiment, the effects of Oridonin on hemody-namics of anaesthetized rabbits were studied. Hemodynamics effects of Oridonin (3.0 mg, 10.0mg/kg iv)were noticed. LVSP, ?dP/dt_max, Vpm, Lo, HR, SBP, DBF were decreased. t-dP/dt_max was increased. LVEDP did not changed. Oridonin decreased DBP more than SBP, it is suggested that Oridonin. may reduce vascular smooth muscle tone.

Objective To investigate mechanism and clinical effect of implantation of pacemaker with artial fibrillation(Af) preventive pacing algorithms (Vitatron 900E).Method 24 cases of patients with paroxysmal Af were observed in three phases (each phase two weeks):⑴Monitoring phase,in which onset mechanism of atrial arrtythmias was recorded, the device was programmed into DDD mode with 60 bpm;⑵Lower rate limit phase (LRL),DDDR mode with 85bpm LRL, and evaluating anti-Af effect by elevated rate;⑶Preventive pacing therapy phase,all preventive pacing therapies with programming to on or off, and this phase determined whether combined pacing therapies impacted on incidence of Af. Results 24 cases of patients were free of Af, in which 17 cases were done by using post-PAC-response or/and post-exercise-rate-control therapy only, and 7 cases of 17 casees were done by combining it with cordarone 0 1～0 2g/d also. The other 7 cases were done by DDDR 85 bpm only.Conclusions Af prevention pacing may be benefit for patients with paroxysmal Af,especially with complicated symptomatic bradycardia.
