1.Key elements to break through registration barriers on traditional Chinese medicine in EU.
China Journal of Chinese Materia Medica 2014;39(15):2972-2977
The EU is an international bridge of traditional Chinese medicine (TCM), and TCM in EU is of strategic importance. In this paper the progress on policies and regulations and approved products of herbal medical products in EU in 10 years were briefly reviewed, registration regulations were systematically, studied and some typical cases were analyzed. To provide reference for successful registration of TCM in EU and implementation of international strategy of TCM, five key elements (i. e. registration classification, approval procedure, approval authority, application product and application enterprise) to break through the registration barriers on TCM in EU were putted forwards correspondingly.

Objective To explore the feasibility of detecting the mutations of rpoB gene in rifampin-resistant Mycobacterium tuberculosis strains by gene chip. Methods The DNA chip was designed according to the sequence of Mycobacterium tuberculosis rpoB gene. The DNA fragments which contained hot mutation sites of rpoB gene were labelled with cy3 fluorescence, amplified by PCR technique and hybridized with gene chip. The DNA sequencing was used as the control. Results Eighteen of the Mycobacterium tuberculosis strains were detected for the mutations of rpoB gene by gene chip. Among them, one sensitive strain was identical with the type strain, and all of 17 strains with rifampin-resistant, rpoB mutations were detected. Of the 17 strains with rpoB mutations, 14 were detected as single point mutation, one was detected as double sites point mutations with the sites of 511 and 516, and two were detected as single point mutation with the sites of 518 and 526, respectively. Because the probe of 517 rifampin-resistant did not be dotted on the gene chip, only sites of 518 and 526 mutations were detected, which were consistent with the results of DNA sequencing. Conclusion Using the gene chip could detect mass rpoB gene mutation of rifampin-resistant with higher specialty and sensitivity, which could be used for clinical detection of rifampin-resistant strains and clinical medicine.

The ultrasound part of “2015 American Thyroid Association Management Guidelines for Adult Patients with Thyroid Nodules and Differentiated Thyroid Cancer” is comprehensive and informative. The content includes the indications for thyroid ultrasound and aspects needed to be evaluated, malignancy risk prediction based on sonographic pattern, decision-making based on ultrasound appearances, follow-up of benign thyroid nodules and surveillance of persistent and recurrent thyroid cancer with ultrasound. Compared with 2009 version of American Thyroid Association (ATA) guidelines, there is a great deal of development. The most important revision was that it analyzed ultrasound pattern of risk stratiifcation of malignancy in thyroid nodules and gave a detailed description of relevant concepts and definitions. Altogether, the new guidelines provided an algorithm for evaluation and management of patients with thyroid nodules based on sonographic pattern and ifne needle aspiration (FNA) cytology. Comprehensive review of the guidelines and appropriate adjustment in practices will make ultrasound examination more reasonable and may enhance the level of medical practices basically..

BACKGROUND: Ureaplasma urealyticum may cause female genital tracts infection and lead sterility, infertility and spontaneous abortion. But it still is not clear whether Ureaplasma urealyticum is one of the factors responsible for fetal malformation.OBJECTIVE: To investigate whether Ureaplasma urealyticum is one of the key factor responsible for fetal malformation.DESIGN: Non-randomized observation of compromised children and their parents with concurrent control.SETTING: The department of immunology and microbiology of a medical college.PARTICIPANTS: Totally 16 malformed fetuses(3 female and 13 male cases) and their parents were chosen from the family seeking pregnancy care in the Department of Gynecology and Obstetrics of the First Affiliated Hospital of Luzhou Medical College and Luzhou First People's Hospital from 1995 to 1997.METHODS: Ureaplasma urealyticum detection was performed in 16 samples of the umbilic blood of the malformed fetuses, sperms of the father, and cervical mucus of the mother who conceived the malformed fetus. The 11 couples positive for Ureaplasma urealyticum were treated with macrolides and aminoglycoside antibiotics and followed up for the outcome of the following pregnancy.MAIN OUTCOME MEASURES: The relation between Ureaplasma urealyticum infection and fetal malformation was examined.RESULTS: Totally 11 of the 16 umbilical blood samples(69% ) were positive for Ureaplasma urealyticum, and serological tests of parents in the 11 positive cases detected rubella virus, cytomegalovirus or Toxoplasma gondii antibodies, nor was abnormality found in chromosomal examination. The following pregnancies and delivery were followed up in 4 women, and the babies showed no functional or organic abnormities with good development till the age of 2 years.CONCLUSION: Female genital tract Ureaplasma urealyticum infection is related to fetal malformation, which provides evidence to support interventions of the occurrence of fetal malformation.

Objective To investigate the effect of valsartan,an angiotensinⅡtype 1 receptor (AT1 R)blocker,on radiosensitivity,invasive potential and proliferation activity of nasopharyngeal carcinoma cells(CNE-2)in vitro. Methods Radiosensitization of valsartan on CNE-2 cells in vitro was investigated by colony forming assay.Effect of ATl R blocker combined with radiation on invasive potential of CNE-2 cells was evaluated using 24-well Matrigel invasion chambers(Transwell).Apoptosis-inducing effect of valsartan combined with radiation on apoptosis of CNE-2 was identified by flowcytometry(FCM). Resuits When valsartan was given at 10-9.10-8 and 10-7 mol/L combined with radiation,sensitivity enhancement ratios (SER)were 1.10,1.20 and 1.36.and the invasive inhibition rates were 8.11%,16.49%and 16.77%,respectively.The SER of valsartan on CNE-2 distinctly increased when the exposure time was increased.After 24 h exposure to 10-8 mol/L valsartan combined witIl radiation.the apoptosis rate was 1.89%±0.09%,which was higher than 1.62%±0.06%in radiation alone group(t=4.79.P<0.05). Conclusions AT1 R blocker valsartan combined with radiation can significantly inhibit the proliferation activity of nasophar,cngeal carcinoma cells in vitro in a dose- and time-dependent manner.Valsartan combined with radiation can potently inhibit the invasive potential of CNE-2.which may be involved in the mechanism of valsartan treatment in vivo.

Objective:To explore the wound-healing effect and the anti-inflammatory activity of the aqueous extracts from the fresh roots and rhizomes of A. calamus. Methods: The image analysis techniques and the histological analysis were used to determine the wound-healing effect in the excised wound test, and the real-time RT-PCR techniques was used to evaluate the anti-inflammatory activi-ty in the lipopolysaccharide-induced RAW 264. 7 cells test. Results:The aqueous extracts were given 3 times a day since the model was established. The skin wound area was reduced significantly in the aqueous extracts group when compared with that in the control group since the 3rd day, the wound area in the aqueous extracts group was only 15% of that in the control group on the 13th day, and the wound-healing rate was enhanced significantly by the extracts. Moreover, the mRNA expressions of the inflammatory mediators such as TNF-α, IL-1β and IL-6 in the inflammatory RAW 264. 7 cells induced by lipopolysaccharide were inhibited effectively by the ex-tracts in a dose-dependant manner. Conclusion:The results indicate that the aqueous extracts from the fresh roots and rhizomes of A. calamus have significant wound-healing activity in animal excised wound model and anti-inflammatory activity in vitro.
