Depression is a common mental disorders, severe cases may affect people's lives. In the treatment of de-pression, appropriate medication, as an assistant approach to psychological support, is proved helpful to patients' re-covery. Western medicine's ingredients are simple and mechanism is clear. Given it meets parts of the demand, the total effect is not satisfactory yet. Traditional Medicine's advantage is systematic, it has advantage in treating complex diseases. Thus, more and more attention was paid to Traditional Medicine, especially Traditional Chinese Medicine (TCM). In this paper, we use patent as data source to discover the law of the TCM's usage, the international differ-ences, the outstanding organization, and the hotspots of the drug research in the treatment of depression. Profiling of the current status can provide references in new drug finding and the progress of pharmacy. The results show that there are a few traditional Chinese medicine patents about treatment of depression associated with kidney, but de-pression and kidney also have a higher correlation. Medicines within soothing liver formulas such as Xiaoyaosan have many related patent.

A . Senticosus is a common medicinal plants, mainly used parts are the dried roots, rhizomes and stems. Since ancient time, it has been regarded as one of top grade medicabecause of its safety and various medicinal properties. To further the development and utilization, a survey of patent information is very helpful to outline the current status of the drug. In this paper, Espacenetand World Traditional Medcine Patent Database were used to perform patent retrieval. Then the dataset were screened, standardized and analyzes via Python and R. The result indicates that, A . Senticosus, given being used for a long history, has less invention patents application comparing with other TCM drugs. The applications mainly come from China, Korea, Japan, Russia, and USA. The major functions includes systemic protection, anti-toxic agent, and treatments of nervous system, digestive system, metabolic, immune and allergic diseases. As to the compatibility of medicines, it often associated with tonic medicine, especially Buqi medicine.

In this paper, the patent of traditional medicines of type-2 diabetes mellitus before 2014 were searched, totally 1 229 patent family information were obtained. The patent information including developing trends, geographic distribution, competitive agencies, technical focus, herbs preferences and so on were analyzed. China is in a leader position on the number of applying patent of using traditional medicine to treat type-2 diabetes mellitus, and the main applications were research institutes, universities and pharmaceutical enterprises. Although the views and theo-ries on treatment of type-2 diabetes mellitus are variety and abound, the most frequently used traditional medicines are tonics and heat-clearing. This article reflected the history, clinical treatment way, developments, application of the diabetes traditional drugs after a meta-analysis,efforts to guide a better understanding and further research.

Patent documentation is a kind of high-value scientific literature. In this paper, the World Traditional Medicine Patent Database (WTMPD) was used to retrieve patents of the traditional medicines used in the treatment and prevention of alcoholic worldwide in the past 30 years. A total of 3 238 patents were further screened by a se-ries of processes. Finally, multi-angle analysis was carried on the dataset to form a patent analysis report on tradi-tional medicines used in alcoholism, including the distribution of the patents, the application trend, the domestic and foreign geographical layout, the major applicant and so on. From the analysis, we found that China had a rapid in-crease in the number of patent applications, which was in the leading role in the world, though the technology and the number of PCT applicant from China is relatively low. Puerariae Lobate radix and flos are frequently used in al-coholism patents.

AIM:To investigate the effect of cigarette smoking condensate on histone deacetylase 2 (HDAC2) and inflammatory mediators in mouse myoblast C 2C12 cells.METHODS:C2C12 cells were treated with cigarette smoke extract (CSE).HDAC2 siRNA was transfected into the cells using Lipofectamine TM 2000.The levels of interleukin-8 (IL-8) and tumor necrosis factor-α( TNF-α) in the culture supernatants were measured by ELISA , and the expression of HDAC2 at mRNA and protein levels was determined by real-time PCR and Western blotting .RESULTS:The expression of HDAC2 at mRNA and protein levels in CSE group was lower than that in control group (P<0.05).The supernatant levels of IL-8 and TNF-αin CSE group were significantly higher than those in control group ( P<0.05 ) .When the cells were transfected with HDAC2 siRNA followed by CSE stimulation , the expression of HDAC2 at mRNA and protein levels was de-creased , and the supernatant levels of IL-8 and TNF-αwere significantly increased as compared with CSE group and control group (P<0.05).CONCLUSION: Under the oxidative stress condition , C2C12 cells generate high levels of IL-8 and TNF-αby down-regulating the expression of HDAC2.

Objective To investigate the relationship of epidermal growth factor receptor (EGFR) mutation with clinical features of baselines as well as serum CEA level in patients with recurrent non-small cell lung cancer (NSCLC). Methods A total of 54 patients with first recurrence of advanced lung cancer who had received chemotherapy were included in this study. ADx-ARMS was performed to detect EGFR gene mutations in surgical specimens taken from the primary tumor. Serum CEA level was measured by the electrochemical luminescence method. Results The mutation rate of EGFR was significantly higher in females than in males (χ2= 11.868, P =0.006), with a total mutation rate of 60.8%in 106 patients. The rate was higher in adenocarcinoma than in other histological types(χ2=6.002,P=0.014), and significantly higher in non-smokers than in smokers (χ2= 8.502,P=0.004) and in the patients with serum CEA level over or equal to 5.0 ng/mL than those with CEA level less than 5.0 ng/mL (χ2=22.543,P=0.000). A multivariate analysis revealed that a higher serum CEA level at the time of disease recurrence was associated with EGFR gene mutations (P = 0.002). Conculsions Serum CEA level is closely associated with the presence of EGFR gene mutations in patients with first recurrence of advanced NSCLC. A higher serum CEA level at the time of disease recurrence is independently associated with EGFR gene mutations. CEA level can be used as a potential indicator to determine EGFR mutation.

Ginkgo bilobaL. is one of the most common used medicinal plants worldwide. The mainly medicinal parts are dry leaf and dry seed. Root and stem also have medicinal value. It has been only found in the wild in Tianmu Mountain, Zhejiang Province, China, while cultivated in a much wider area. Since ginkgo is an important plant resources, a comprehensive overview is necessary, which can help understand the current status and the development trends. In this study, the patent information fromEspacenet and World Traditional Medicine Databaseis used to outline the technology development of ginkgo in the perspective of invention patents. The results showed that ginkgo development currently in the early or mid-term maturity period. Ginkgo got the best development in China. Most international exchange of intellectual property happened in United States. More attention has been paid to the development ofG. biloba leaf. Ginkgo’s medicinal application and compatibility were also analyzed in this study.
