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.

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.

Objective To compare the safety,feasibility,and long-term outcomes between combined thoracoscopic and laparoscopic esophagectomy (TLE) and open three-field esophagectomy (OE) for esophageal cancer.Methods The data of 183 patients with esophageal cancer who accepted TLE (n =94) or OE (n =89) from February 2009 to December 2011 were retrospectively collected and compared.Results Demographics,pathologic data in each cohort were almost identical.No significant differences were observed in operative time,the number of lymph node harvested,rates of anastomotic leak,thoracic abscess,chyle chest,re-operation,vocal cord paralysis,gastric emptying dysfunction and morbidity.A significant difference was observed in blood loss (86.6 ±38.3 ml in TLE group vs.217.4 ±87.2 ml in OE group,P=0.000),rate of transfusion (1.1％ vs.6.7％,P =0.045),hospital stay (13.9 ±7.5 d vs.17.1 ±10.2 d,P =0.017),rate of overall surgical complications (23.4％ vs.38.2％,P =0.030),rate of pulmonary complications (9.6％ vs.27.0％,P =0.002) and rate of arythmia (4.1％ vs.12.4％,P =0.046).Median follow-up time was 28.0 ±2.0 months (95％ CI:24.2-31.8).No difference between the two groups concerning survival was observed (P =0.954).Conclusion The TLE for esophageal cancer is safe and feasible.Although it cannot improve the survival of long-term,it is worth spreading in intraoperative and postoperative advantages compared with OE group.

BACKGROUND: Diabetic nephropathy is one of the most serious vascular complications of diabetes mellitus. Compound preparation of huangqi and dahuang, a traditional Chinese medicine, has been used to preventing or treating diabetic nephropathy for several years, and has a certain protective effect on the kidney of diabetes mellitus patients. But its exact mechanism remains unknown and needs to be studied more.OBJECTIVE: To investigate the effect of compound preparation shenkang wan on the proliferation and secretion of extracellular matrix in cultured rat mesangial cells induced by high glucose.DESIGN: Randomized and controlled study.SETTING: Center of Integrated Traditional and Western Nephrology of Zhujiang Hospital and Medicine Department of Nanfang Hospital, Southern Medical University.MATERIALS: The serum pharmacological experiment was performed in Animal Experimental Center of Southern Medical University in A pril 2005.The cell culture experiment was conducted in Cell culture room of Southern Medical University from April 2005 to July 2005. Totally 16 normal Wistar male rats, weighted varied from 190 g to 220 g, were used in the study.METHODS: Sixteen normal Wistar male rats were randomly divided into 4 groups: normal serum group, capoten group, shenkang wan group (high dose and low dose); shenkang wan was mainly constituted of huangqi,dahuang, leech, gordon guryale seed and corn stigma and made in Pharmacy Department of Zhujiang Hospital of Nanfang Medical University, agent number: 20031214). ① The rats in capoten group and high and low dose shenkang wan group were given the corresponding drugs respectively according to 5 mg/kg, 2.4 g/kg, 1.2 g/kg weight. The rats in normal serum group were given the same volume water. After treated 7 days, all rats were hocused and separated medication serum. ② Mesangial cell was cultured in vitro with different concentrations of glucose (10, 20, 30 and 40 mmol/L).The proliferation of mesangial cell was observed with the methyl-thiazoltelrazolium colorimetric assay at 24, 48, 72 hours and 96 hours. ③ Then the cultured mesangial cells were divided into six subgroups :Low glucose control group (10 mmol/L glucose), high glucose group (30 mmol/L glucose);normal serum group (30 mmol/L glucose); capoten group (30 mmol/L glucose); shenkang wan group (high dose and low dose, 30 mmol/L glucose).After cultured 72 hours, the proliferation of mesangial cell was detected with the methyl-thiazol-telrazolium colorimetric assay, the secretion and mRNA gene expression of fibronetin levels in mesangial cell were respectively detected by enzyme linked immunosorbent assay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR) method.MAIN OUTCOME MEASURES: ①Proliferation of mesangial cell induced by different concentrations glucose. ② Proliferation and secretion and mRNA gene expression of fibronectin in every group.RUSULTS: ① Effect of different concentrations glucose on the prolifera-tion of mesangial cell: Compared with low concentrations glucose(10 mmol/L), 20 mmol/L glucose could accelerate the proliferation ofmesangial cell during 96 hours experiment period, but only had a statisti-cally significant difference at 72 and 96 hours (P ＜ 0.05). 30 mmol/L glu-cose could significantly accelerate the proliferation of mesangial cell thanthat of 10 mmol/L glucose from 24 hours to 96 hours (P ＜ 0.05 or P ＜ 0.01),and this effect was increasing with time in 72 hours and reduced after 72hours. 40 mmol/L glucose could significantly increase the proliferation ofmesangial cell than of low concentrations glucose in 48 hours (P ＜ 0.05),and this effect was reduced after 48 hours and even conversed to restraineffect. ② Effect of different medication serum on the proliferation ofmesangial cell: The optical density value in high glucose group is obviouslyhigher than that of low glucose control group (P ＜ 0.01). Compared withhigh glucose group, the optical density value in capoten, shenkang wangroup (high dose and low dose) was decreased markedly (P ＜ 0.01 or P＜ 0.05). While the optical density value in normal serum group was showedno difference with the high glucose group (P ＞ 0.05). ③ Effect of differentmedication serum on secretion of fibronectin in mesangial cell: Content offibronectin in high glucose group was increased more markedly than that oflow glucose group (P ＜ 0.01). Compared with high glucose group, contentof fibronectin in capoten and shenkang wan group (high dose and low dose)was showed a significantly decrease (P ＜ 0.01 or P ＜ 0.05), while contentof fibronectin in normal serum group was showed no difference with thehigh glucose group (P ＞ 0.05). ④ Effect of different medication serum onexpression of fibronectin mRNA in mesangial cell: The optical density val-ue of fibronectin strip in high glucose group was brighter than that in lowglucose group and the ratio of it and β-actin were increased markedly too(P ＜ 0.01). Compared with high glucose group, the optical density value offibronectin strip in capoten and shenkang wan group (high dose and lowdose) was showed a significantly decrease and the ratio of it and β-actinwas reduced distinctly too (P ＜ 0.01), while the ratio of it and β-actin innormal serum group was showed no difference (P ＞ 0.05).CONCLUSION: High glucose could accelerate proliferation, increase thesecretion and mRNA gene expression of fibronectin in mesangial cell,while shenkang wan could inhibit proliferation and secretion of the extra-cellular matrix in mesangial cell induced by high glucose.
