ABSTRACT
Tubulin has been shown to be an effective target for the development of cytotoxic agents against prostate cancer. Previously, we reported that Lx2-32c is an anti-tubulin agent with high binding affinity to tubulin. In this study, we investigated the potential of Lx2-32c to act as an effective cytotoxic agent in the treatment of prostate cancer. MTT assays showed that Lx2-32c was cytotoxic to all tested prostate cancer cell lines. The Lx2-32c-treated cells typically exhibited a rounded morphology associated with the onset of apoptosis, as evidenced by immunocytochemical staining. Human prostate cancer cell lines treated with Lx2-32c arrest in the G2/M phase of the cell cycle and the treatment is associated with an increased ratio of cells in the sub-G0/G1 phase as determined by flow cytometry. Furthermore, expression of the cleaved form of poly (ADP-ribose) polymerase in prostate cancer cell lines treated with Lx2-32c was shown by Western blotting assay. Xenograft implants of LNCaP and PC3-derived tumors in nude mice showed that Lx2-32c treatment significant inhibited tumor growth with effects equivalent to those of docetaxel. These findings demonstrate the potential of Lx2-32c as a candidate antitumor agent for the treatment of prostate cancer.
ABSTRACT
This study was aimed to assess the methodological quality of systematic literature reviews on the efficacy and safety ofTong-Xin-Luo(TXL) using the AMSTAR statement. The literatures were searched from major domestic and international databases include the CJFD Database, VIP Database, CNKI database, CBM Database Online, WanFang Data and TCM Database, Medline, Pubmed, ISI Web of knowledge, Web of science, from the database was built to 20th December, 2014. And 5 evaluators screened the literatures independently according to the inclusion and exclusion criteria. Then, all systematic reviews were assessed using the list of AMSTAR statement. The results showed that 22 literatures were finally included, which contained 17 systematic reviews and 5 meta-analysis. In the included literatures, there were different degrees of impairments on the methodological and reporting quality, which were mainly focused on program and registration, retrieving and collecting literatures, inclusion and exclusion criteria, authentic assessment, data processing, funds, and etc. The average reporting rate of AMSTAR statement was 57.02% in all included literatures. It was concluded that the methodological quality of systematic literature reviews on the efficacy and safety of TXL was relatively low from the current level of average reported rate, which affected the quality of the article. It indicated that there were different degrees of impairments in all links of test reports in current systematic reviews, which will be bound to affect the reliability of clinical evidence and the determination of clinical decision. It showed that the methodological quality of writing of such articles should be in compliance with entries of AMSTAR statement to improve its quality.
ABSTRACT
The establishment of the National Clinical Research Base of Traditional Chinese Medicine (TCM) is very helpful for TCM research. The construction of a Chinese medicine research laboratory is an important part of the National Clinical Research Base of TCM. In this paper, researches on Chinese medicine laboratory construc-tion were discussed. It was combined with the actual construction of research laboratories of our hospital. This ar-ticle also discussed the geographical features and clinical needs of the National Clinical Research Base of TCM construction. Ideas of laboratory plan, open laboratory and experimental shared services platform construction were put forward in advance .
ABSTRACT
This article summed up experiences in construction of the national traditional Chinese medicine (TCM) clinical research base, elucidation of Xinjiang TCM clinical research base of experiences in building a full range of the protection of the operating mechanism, characteristics, effects, and good advice for a number of deficiencies in the management of the base.
ABSTRACT
[Objective] To inquire the national distribution of the Xinjiang residents of Northwest Dryness Syndrome's (NDS) rate.[Methods] To study the national distribution of NDS's rate at Yili,Hami,Urumqi in Xinjiang using the Scale Investigation of NDS.[Results] The NDS's rate of the rural residents has the regulation which Han or Kazakans is higher than Uighur in above the three areas,and the cities have the regulation which Han is higher than Uighur in above the three areas.The NDS's rate has the regulation which the city residents are higher than the rural's.The three nations have no difference.[Conclusion] The NDS's rate of the residents in Xinjiang has the regulation which Hami is higher than Urumqi or Yili in above three areas.Maybe,the national difference of eating habits leads the national difference of the NDS's rate and the living environment difference of urban and rural leads the national difference of the NDS's rate.
