With the increase of Chinese people's material life level, their health consciousness has become more and more intense. Chinese Materia Medica, a treasure of Chinese medicine, has made a great contribution in maintaining people's health in the history. Patent is a kind of high-value scientific literature. In this paper, we retrieved the patents of the traditional medicines used in health care worldwide. The patents were further screened by a series of processes. Finally, multi-angle analysis was carried out on the dataset to form a patent analysis report of traditional medicines in health care, including the distribution of the patents, the application trends, the domestic and foreign geographical layout, the major applicant and its activity, the important technical areas, the important medicinal and its pharmacological properties and so on.

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.

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.

Objective To observe the clinical effects of anti-vascular endothelial growth factor (VEGF) agent for retinopathy of prematurity (ROP) in different zones.Methods Retrospective analysis was performed on 24 ROP patients (46 eyes) who received intravitreal injection of anti-VEGF agent in our hospital from April 2013 to April 2014,including 15 patients (28 eyes) with Zone Ⅰ ROP and 9 patients (18 eyes) with Zone Ⅱ ROP.All the patients receive intravitreal injection of anti-VEGF agent Ranibizumab.The patients were observed for postoperative progression of fundus conditions,and the recovery rate and progression rate following initial injection were compared statistically between two groups.Results There was no statistically significant difference between the two groups in gestational age at birth or birth weight (both P >0.05);And statistically significant difference was found between two groups in gestational age at surgical correction (P =0.001).Following initial injection,the recovery rates were 32.14% and 66.67%,and the progression rates were 67.86% and 33.34% in Zone Ⅰ ROP group and Zone Ⅱ ROP group,respectively,there was statistically significant difference between the two groups in recovery rate (x2 =5.263,P =0.022).The progression rate in Zone Ⅰ ROP group was higher than that in Zone Ⅱ ROP group,there was statistically significant difference (x2 =-2.269,P =0.023).During follow-up,no complications of intravitreal injection as cataract,endophthalmitis or retinal tears was observed;Only 2 patients experienced corneal edema,and 4 patients experienced subconjunctival hemorrhage.Conclusion Intravitreal injection of anti-VEGF agent is effective for both Zone Ⅰ and Zone Ⅱ ROP.While for Zone Ⅰ ROP,the surgery success rate is low and the reoperation rate is high,such treatment can provide favorable time and conditions for reoperation.

Background Evidence-based medicine (EBM) has been widely applied to solve clinical issues internationally,however,the awareness of oculists in China still is dissatisfied,and the relevant issue survey can offer the training guidance.Objective This study was to survey the status of the cognition and practice of EBM in ophthalmologists in China and analyze the problems in their EBM practice.Methods Two hundred and thirty-three ophthalmologists were enrolled in the 18th Congress of Chinese Ophthalmological Society in August,2013.A survey about EBM was performed by self-made questionnaire,including general data from the surveyors,the way and channel of understanding EBM,the attitude toward EBM,clinical practice of EBM and influencing factors.The educational background,professional qualifications,ranked distribution of hospitals which surveyors came from,size of the citys and attribute of hospitals were stratified and analyzed.SPSS 17.0 software was used for statistical analysis.Results A total of 233 questionnaires were distributed,and 233 were regained with the response rate 100%,and 214 valid questionnaires were included,with the effective rate 91.8%.50.5% of the respondents (104/206) knew EBM in university.The proportion of those believe EBM initially as medical students was 41.8%,and 49.1% (102/208) were aware of EBM in recent 8 years.And 47.7% (101/211) believed that EBM should be given priority in clinic,and 7.5% (16/211) were indifferent to EBM.Only 3.8% (8/211) surveyors thought EBM to be little important.The proportion of the respondents choosing ‘ know’ or ‘ moderately-know’ were 69.1% (148/214),35.0% (75/ 213),21.5% (46/213) and 57.4% (121/211) respectively in EBM,Meta analysis,Cochrane as well as Preferred Practice Patterns (PPPs) with a higher receiving degree in well-educated individuals (P =0.000,0.000,0.001,0.000).EBM was well practiced in 11.7% (25/211) oculists,with a higher using frequency in senior ophthalmologists,and 17.8% (89/495,frequency) oculists consulted the EBM literature to resolve problems in clinic,with a significant difference in the using frequency of EBM among the different educational background subjects (x2=13.406,P=0.037).The top three barriers which affected the application of EBM in clinical practices were lack of time and the limited energy,feeling it difficult to evaluate the evidence correctly as well as the absence of cases proving the efficacy to treat based EBM.The type of EBM evidence mostly used by respondents was medical database (36.7%),and CNKI (33.5%) and PubMed (38.4%) were the mostly used Chinese and English database,respectively.Respondents who have never searched the Chinese or English database occupied up to 7.3% and 17.2%,respectively.Conclusions The cognition degree and applying frequency are still lower in ophthalmologists in China.The training of EBM should be strengthened in medical students.The guidance measurement should be taken to encourage eye doctors to apply EBM.

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.
