ABSTRACT
The outbreak and spread of coronavirus disease 2019 (COVID-19) highlighted the importance and urgency of the research and development of therapeutic drugs. Very early into the COVID-19 pandemic, China has begun developing drugs, with some notable progress. Herein, we summarizes the anti-COVID-19 drugs and promising drug candidates originally developed and researched in China. Furthermore, we discussed the developmental prospects, mechanisms of action, and advantages and disadvantages of the anti-COVID-19 drugs in development, with the aim to contribute to the rational use of drugs in COVID-19 treatment and more effective development of new drugs against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the variants. Neutralizing antibody is an effective approach to overcome COVID-19. However, drug resistance induced by rapid virus mutation will likely to challenge neutralizing antibodies. Taking into account current epidemic trends, small molecule drugs have a crucial role in fighting COVID-19 due to their significant advantage of convenient administration and affordable and broad-spectrum. Traditional Chinese medicines, including natural products and traditional Chinese medicine prescriptions, contribute to the treatment of COVID-19 due to their unique mechanism of action. Currently, the research and development of Chinese anti-COVID-19 drugs have led to some promising achievements, thus prompting us to expect even more rapidly available solutions.
ABSTRACT
Background and purpose:Although intermittent endocrine therapy is a treatment strategy for new patients with advanced prostate cancer, the use of hormonal therapy is still controversial. This study aimed to investigate the efficacy of intermittent hormonal therapy for the patients with advanced prostate cancer and determine the factors influencing efficacy of the treatment.Methods:From Jul. 2009 to May 2015, patients with advanced prostate cancer were treated with 6 months of hormonal therapy, and then efficacy was assessed. A hundred and twenty-eight hormone sensitive patients were randomly divided into intermittent and continuous treatment groups, and were observed with efficacy, side effects, quality of life scores and other indicators. The prognostic factors for intermittent group were analyzed.Results:A total of 128 patients with advanced prostate cancer were enrolled in the study. Prostate-specific antigen (PSA) levels were significantly decreased in 96 patients after endocrine therapy. Among those, 43 patients received intermittent endocrine therapy while 53 patients received continuous endocrine therapy. The score of KPS in the intermittent treatment group was 82.6±7.4, which was significantly higher than that of the continuous group (KPS score was 69.8±8.7). There was a sig-nificant difference between them (P0.5). PSA level in the early stage of endocrine therapy and G1eason score before treatment were important factors affecting the prognosis of patients. The patients in the intermittent group were followed up for 13-70 months, and received 1 to 4 cycles of treatment. The number of patients in the treatment was declined during the extension of the treatment, and the treatment interval was shorter.Conclusion:Intermittent endocrine therapy is an effective treatment for advanced prostate cancer. It is safe and reliable. It can improve the quality of life for patients and reduce the economic burden on them.
ABSTRACT
Moxibustion,which is simple for manipulation and effective,has always been a very important way for external treatment.Acupuncture and moxibustion were complementary to each other sincc ancient times.but modem people usually only pay attention to acupuncture and neglect the usage of moxibustion.In this paper the importance of moxibustion is expounded briefly.
ABSTRACT
S. The migration of CNE-2Z cells was inhibited by chloride channel blockers (ATP, NPPB and tamoxifen), but the inhibitory effect of the blockers varied with cells at different stages. CONCLUSIONS: The migratory ability is associated with the cell cycle in CNE-2Z cells. Chloride channels play an important role in cell migration of CNE-2Z cells.
