1.Enlightenment of drug application and evaluation procedures of medicines registered (listed) in Australia on studies of new traditional Chinese medicines.
China Journal of Chinese Materia Medica 2014;39(21):4265-4267
Modern and international studies on new traditional Chinese medicines are the main trend of the development of traditional Chinese medicines at present. In Australia, new traditional Chinese medicines refer to complementary medicines, which are mainly registered and launched as listed medicines. The application documents of registered (listed) medicines in Australia mainly cover detailed description of active pharmaceutical ingredients, pharmacological and toxicological studies, dosage form and adverse effects. Each part has detailed specifications and instructions, which helps ensure that applicants could accurately understand the requirements in application for registering (listing) medicines, and provides very important reference to the studies and development of new traditional Chinese medicines in China.

OBJECTIVETo compare differences of therapeutic effect between acupuncture method of tonifying-qi and dredging-meridian and conventional acupuncture method.
METHODSSeventy cases of blepharospasm were randomly divided into an observation group and a control group, 35 cases in each one. Cuanzhu (BL 2), Yuwei (Extra) through Yuyao (EX-HN 4), Xinming 1 (Extra), Sibai (ST 2) and Yintang (GV 29) were selected as main acupoints. The acupuncture method of tonifying-qi and dredging-meridian was applied in the observation group, which was an acupuncture manipulation that could achieve strong needling sensation of qi arrival combined with electric-impulse stimulation. The conventional acupuncture method was applied in the control group. The treatment was given once every other day, 10 times as a session for continuous three sessions in both groups. The severity of blepharospasm was compared before and after treatment in two groups and clinical therapeutic effect was assessed. Follow-up visit was performed after half a year to observe the recurrence rate.
RESULTSThe cured and markedly effective rate was 77.1% (27/35) in the observation group, which was superior to 51.4% (18/35) in the control group (P < 0.05). Among cured and markedly effective patients in both groups, the recurrence rate was 20.0% (4/20) in the observation group, which was inferior to 54.5% (6/11) in the control group (P < 0.05) in the follow-up visit.
CONCLUSIONThe acupuncture method of tonifying-qi and dredging-meridian could effectively improve severity of blepharospasm, which has superior short-term and long-term effects to conventional acupuncture method.

4.Drug design ideas and methods of Chinese herb prescriptions.
China Journal of Chinese Materia Medica 2015;40(17):3413-3415
The new drug of Chinese herbal prescription, which is the best carrier for the syndrome differentiation and treatment of Chinese medicine and is the main form of the new drug research and development, plays a very important role in the new drug research and development. Although there are many sources of the prescriptions, whether it can become a new drug, the necessity, rationality and science of the prescriptions are the key to develop the new drug. In this article, aiming at the key issues in prescriptions design, the source, classification, composition design of new drug of Chinese herbal prescriptions are discussed, and provide a useful reference for research and development of new drugs.

OBJECTIVETo discuss that pathogenesis evolvement regularity of Chinese miniature swine with phlege-stasis cementation syndrome of coronary heart disease.
METHODEighteen Chinese miniature swine were randomly divided to the normal control group, the model group and the Danlou tablet group, with six swine in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. The levels of BMI, hemorheological parameters, lipids in serum and inflammatory cytokines were observed at the 0th (before the experiment), 2nd (before operation or drug administration), 6th (four weeks after drug administration) and 10th week (eight weeks after drug administration) of study. The levels of TG and TC in liver and the pathological changes in coronary artery tissues were also observed at the end of study.
RESULTCompared with the normal control group, the model group had showed significant increase in the levels of TC, TG, LDL-C and VLDL-C in serum (P < 0.01) from the second week to the end of the experiment, with notable rise in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1). At the 6th week, the levels of BMI and TG and TNF-alpha in serum significantly increased. At the 10th week, the levels of BMI and hs-CRP, IL-6 and TNF-alpha in serum significantly increased as well, with remarkable increase in coronary stenosis, intimal thickness and the ratio between intimal thickness and media thickness (P < 0.05 and P < 0.01), and significant rise in TC and TG in livers (P < 0.01). Compared with the model group, the Danlou tablet group showed obvious reduction in severity of coronary artery lesion, intimal thickness and lumen stenosis ratio and ratio between intimal thickness and media thickness (P < 0.01), BMI, TC, TG, LDL-C and VLDL-C in serum, TC and TG in liver, as well as hs-CRP, IL-6 and TNF-alpha levels in serum (P < 0.05 and P < 0.01), with notable decline in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1).
CONCLUSIONThe interaction of phlegm, blood stasis and toxin syndromes helps promote the progress and development of AS plaques, which is the key pathogenesis of phlegm-stasis cementation syndrome in coronary heart disease.

OBJECTIVETo establish the "clinical-mimetic" Chinese medicine symptom complex score method for the coronary heart disease Chinese miniature swine model with phlegm-stasis cementation syndrome, in order to observe the effect of formula of removing both phlegm and blood stasis (TYTZ) on the Chinese medicine symptom complex score for the coronary heart disease Chinese miniature swine model with phlegm-stasis cementation syndrome.
METHODTotally 36 Chinese miniature swine were randomly divided to the normal control group, the model group, the Shujiangzhi group, and TYTZ groups with doses of 2.0, 1.0 and 0.5 g x kg(-1), with six in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. After the operation, the groups were administered with drugs for eight weeks. Their main symptoms, accompanied symptoms, tongue and pulse signs of the coronary heart disease Chinese miniature swine with phlengm-stasis cementation syndrome were observed according to the symptom-graded scoring method.
RESULTCompared with the model group, TYTZ in different doses could reduce the scores of main symptoms at the 6th and 10th week. Specifically, TYTZ in low dose could reduce the scores of tongue at the 6th week and the scores of accompanied symptoms, and tongue and pulse signs at the 10th week; And TYTZ in high dose could decrease all symptom scores at the 6th and 10th week (P < 0.05 or P < 0.01).
CONCLUSIONTYTZ can improve the scores of the main symptoms, accompanied symptoms, tongue and pulse signs in coronary heart disease Chinese miniature swine with phlegm-stasis cementation syndrome. It is suggested that the "clinical-mimetic" objective scoring for syndromes of Chinese miniature swine is of great significant to the development of new traditional Chinese medicine drugs.

Dengue virus (DENV) is a re-emerging disease transmitted by the Aedes mosquitoes and has become a major public health problem in southern China. Currently, no antiviral drug or effective vaccine exist to control this disease. The chimeric DENV structural protein vaccine cannot elicit balanced levels of protective immunity to each of the four viral serotypes; therefore, non-structural protein components may be required to construct an effective DENV vaccine. The Dengue virus non-structural 1 (DENV NS1) protein plays a critical role in viral pathogenesis and protective immunity. Therefore, immunity to Dengue 1-4 NS1 subtypes may be crucial for the prevention of severe disease. This review attempts to provide an overview about the structure and function of DENV NS1.
