1.Research on strategy of intellectual property protection of traditional Chinese medicine from the perspective of enterprise
International Journal of Traditional Chinese Medicine 2014;(7):577-580
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.
2.Study of strategies on traditional Chinese medicine accessing Australian market
International Journal of Traditional Chinese Medicine 2011;33(6):511-514
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.
3.Study on barriers of policy and regulation of traditional Chinese medicine accessing international markets and its countermeasures
International Journal of Traditional Chinese Medicine 2012;34(1):28-32
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.

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.

Objective To investigate the effects of local delivery c-myc antisense oligodexynucleotides on neointimal hyperplasia after angioplasty in rabbits. Methods The celiac arterial endothelium of 75 male Japanese white rabbit (2.5?0.5 kg) were denuded after being fed with cholesterol-supplemented diet to establish the model of atherosclerotic stenosis of celiac arteries. The animals were randomized into the antisense DNA group (Group Ⅰ), sense DNA group (Group Ⅱ), saline control group (Group Ⅲ) and simple angioplasty group (Group Ⅳ). The drugs were injected intramurally using a porous balloon. The local vessels were collected at the 24 th hour and the 4 th week after the procedure for morphological observation. C-myc mRNA level was measured by means of RT-PCR and c-myc protein with immunohistochemical staining. Results RT-PCR showed that c-myc mRNA level in Group Ⅰ was lower than that of Group Ⅱ, Group Ⅲ and Group Ⅳ after the first 24 hours. The ratio of neointimal area (NEA) to medial area (MA) and NEA/MA in Group Ⅰ were significantly less than those of Group Ⅱ, Group Ⅲ and Group Ⅳ. Immunohistochemical staining showed that the percentage of c-myc protein positive cells was less in Group Ⅰ than those of the other groups. Conclusion Transcatheter local delivery of c-myc antisense oligonucleotides reduces neointimal hyperplasia after angioplasty in rabbits.
8.Clinical and imaging features of primary lateral sclerosis
Journal of Clinical Neurology 2001;0(05):-
Objective To explore the clinical and imaging features of primary lateral sclerosis(PLS).Methods The clinical and imaging data of 3 patients with PLS were analysed.Results 3 patients included 2 females and 1 male.The onset of the disease was insidious.The initial symptoms included rigidity and weakness of right upper limb(case 1),rigidity and weakness of legs(case 2),and pseudobulbar palsy(case 3). As the disease progressed slowly,the patients presented with spastic paralysis of four extremities,reduced muscle strength(3 to 4 degree),clasp-knife like of muscular tension,hyperactivity of tendon reflexes,ankle clonus and presence of Babinski sign.In T2-weighted images of the brain MRI,the abnormal high signals were symmetrically situated in the motor cortex,the posterior limbs of internal capsules,cerebral peduncles and basilar part of pons.1H magnetic resonance spectroscopy(1HMRS) showed decreases of N-acetylasartate(NAA) and the ratio of N-acetylaspartate/Creatine(NAA/Cr) in the focal regions.Conclusion PLS presents with characteristic features of clinical symptoms,signs and abnormal changes of MRI.In addition,1HMRS may be helpful in diagnosis of this disease.

Objective To study the clinical effect and value of the combination of dexamethasone and calcium agent assisted oxytocin on preventing postpartum hemorrhage.Methods 128 cases of maternal of clinical information were reviewed,and which were divided into control group and observation group randomly.The control group was immediately infused muscle note 20IU of Oxytocin and the observation group(n =64) was given 5% of glucose and 100ml 10% of glucose acid 10ml calcium.And then give 20IU oxytocin after pending.Lastly,give the two groups comparison of blood-producing capacity and the number of cases of blood-producing.Results Ater observation groups in fetal foetus blood-producing capacity of 2h and 24h,the number of cases of blood-producing less than the control group,and both have significant statistical differences (all P < 0.01).Conclusion The combination of dexamethasone and calcium agent-assisted application of oxytocin can prevent postpartum hemorrhage,better clinical effect,which should be promot in clinical application.
