Orally disintegrating tablets (ODT), a kind of new solid tablet that rapidly disintegrates to work in the mouth, has became the hot form of new drug research in recent years with many advantages, such as the convenient taking, a widely applicable people, fast acting, high bioavailability, good compliance, and so on. ODT has been widely used in chemical medicines, while the application of it in traditional Chinese medicines (TCMs) is still in the stage of development The development of TCMs ODT provides a new direction for the research of Chinese medicine new dosage, accelerates the pace of connecting to the world and modernization of Chinese medicine. This dosage has a broad market prospect, and its quality control and assessment standards, taste, the disintegration time in vitro and evaluation method are the key factors that affect the industrialization, standardization of Chinese medicine ODT. Therefore, this paper reviewed the characteristics, preparation, taste masking technology and quality evaluation with new technology of ODT. Meantime, numerous application examples of ODT used in traditional Chinese medicine were described. We expect to provide the reference and utilization for the development of traditional Chinese medicine orally disinteeratine tablets.

The secondary development of traditional Chinese medicines (TCMs) is an important content of TCM modernization process, as well as an important path for developing new TCM drugs. Under the guidance of the system theory, in response to the lack of the overall guideline and practical methods for the secondary development of TCMs at present, we introduced the overall thought of the secondary development of major TCM varieties, as well as the roles and contents of clinical research, pharmacology and pharmaceutics in the process of the secondary development of major TCM varieties, so as to provide systematic strategies and methods for the development of major TCM varieties.

The secondary development of major traditional Chinese medicine varieties is one of important links during the modernization, scientification and standardization of traditional Chinese medicines. How to accurately and effectively identify the pharmacodynamic material basis of original formulae becomes the primary problem in the secondary development, as well as the bottleneck in the modernization development of traditional Chinese medicines. On the basis of the existing experimental methods, and according to the study thought that the multi-component and complex effects of traditional Chinese medicine components need to combine multi-disciplinary methods and technologies, we propose the study thought of the material basis of secondary development of major traditional Chinese medicine varieties based on the combination of in vivo and in vitro experiments. It is believed that studies on material basis needs three links, namely identification, screening and verification, and in vivo and in vitro study method corresponding to each link is mutually complemented and verified. Finally, the accurate and reliable material basis is selected. This thought provides reference for the secondary development of major traditional Chinese medicine varieties and studies on compound material basis.

Objective To assess the efficacy and safety of argon plasma coagulation(APC) in treating patients with Barrett's esophagus.Methods Two reviewers independently searched the Cochrane Library(Issue 2,2008),MEDLINE(January 1948 to November 2008),and CNKI(January 1999 to November 2008),respectively.The quality of the included studies was assessed according to the guidance in the Cochrane Handbook of systematic reviews of interventions.Results Six randomized controlled trials involving 253 patients with Barrett's esophagus met the inclusion criteria and were included.One trial reported that the ablation rate of patients in the APC group was significantly higher than that in the endoscopic surveillance group.Followed up one year,the ablation rate in APC group was 63% compared with 15% in the control group(P

The abnormality of ubiquitin proteasome pathway is an important factor leading to the imbalance of protein homeostasis. In this process, the deubiquitinase responsible for removing the ubiquitin chain of protein substrate is very important. Its abnormal activity or expression can cause the functional changes of key oncogenic/tumor suppressor proteins, which directly or indirectly lead to the occurrence, development and malignant evolution of tumors. Based on this, the discovery and research of small molecule inhibitors targeting deubiquitinases have become a hot field of anti-tumor candidate drugs. This review will focus on the regulatory effect and mechanism of ubiquitin proteasome pathway, especially deubiquitinase on tumor, introduce the application of deubiquitinase small molecule inhibitors in tumor treatment, and discuss the research status and latest progress of small molecule inhibitors, so as to provide ideas for the research of new anti-tumor strategies based on deubiquitinase.

Absract: Objective To report the result of annual monitoring and analysis of nasopharyngeal virus in children with respiratory tract infections in Nanxiang, Shanghai District. Methods Nasopharyngeal secretions were collected from 4389 children with acute respiratory tract infection in outpatient department from January 2007 to September 2013, 9 common respiratory viruses were analyzed by Multiplex RT-PCR, including inlfuenza virus (FLU), parainlfuenza virus (PIV), respiratory syncytical virus (RSV) , adenovirus (ADV), human bocavirus(HBOV), human coronavirus(Cov), enterovirus(EV), human metapneumovirus(HMPV), and rhinovirus(HRV). The same analysis was done in 123 asymptomatic children during the same period. Results The positive rate of detected respiratory viruses in children with respiratory tract infections in nasopharyngeal secretions were 34.8% (1526/4389), including FLU 10.3% (453/4389), RSV 7.3% (320/4389), PIV 6.2%(274/4389), ADV 3.3%(146/4389), HBOV 2.7%(118/4389), EV 2.5%(110/4389), Cov 2.4%(105/4389), HRV 1.6%(72/4389), HMPV 1.5%(67/4389);two and more combined respiratory viral infection were found in 273 cases (6.2%). The virus detection
rate between age groups was signiifcantly different (χ2=41.91, P<0.001). The school-age group had the lowest positive rate of 23.4%and the positive rates in other three groups were all higher than 35.0%. The infant group had the higher positive rate of RSV and HRV. FLU detection rate in school-age group was 13.6%. Respiratory viruses in children with asthmatic disease has high detection rate. RSV infection rate was the highest 14.8%(30/204) in the asthmatic disease group, followed by HBOV 13.8% (28/204). In nasopharyngeal secretions of 123 asymptomatic children, virus-positive detection rate of 6.5% (8/123), which showed signiifcant difference from that in respiratory virus infection group (χ2=42.60, P<0.001). Conclusions In seven consecutive years of testing, the inlfuenza virus and respiratory syncytial virus play an important role in children with respiratory tract infections in this region. The detection rate of virus showed difference between different age groups and a higher detection rate of RSV in infants with respiratory tract infections was observed. The overall detection rate of virus was decreased with the increase of age excluding the inlfuenza virus.

DNA barcoding technology is widely opplied for species identification and discovery by using short and standard fragments of DNA sequences. In this study, the cytochrome c oxidase subunit 1 (COI) sequence as a DNA barcode was used to identify the Gekkogecko Linnaeus medicinal materials and adulterants in order to provide a new identification method of G. gecko Linnaeus. Genomic DNA was extracted from the experimental samples. The COI regions of nrDNA were amplified using polymerase chain reaction and sequenced bidirectionally. The alignment and NJ tree construction were performed in MEGA6.0. COI sequences can be obtained from all samples. The average intra-specific K2P distance of G. gecko Linnaeus was 0.005 and the maximum intra-specific distance was 0.013. All the G. gecko Linnaeus medicinal samples clustered into a clade in the NJ tree and can be distinguished from the adulterants. In a conclusion, COI can be used to correctly identify G. gecko Linnaeus, and it will be a potential DNA barcode for identification of other animal medicinal materials.
