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 assess the role of imbalance between regulatory T (Treg) cells and T helper 17 (Th17) cells in the pathogenesis of atopic dermatitis (AD).[Methods] Peripheral blood was obtained from 41 patients with AD and 38 age- and sex-matched healthy controls.Flow cytometry was performed to determine the percentage of Treg cells (CD4+CD25+Foxp3+ T cells) and Thl7 cells (CD4+ILl7+ T cells),real-time quantitative reverse transcription (RT)-PCR to detect the mRNA expressions of Foxp3 and RORγt,which are the specific transcription factors of Treg and Th17 cells respectively.Serum concentrations of transforming growth factor (TGF)-β,IL-17 and IL-23 were measured by enzyme linked immunosorbent assay(ELISA).Data were statistically assessed by independent-samples t test and Pearson correlation analysis.[Results] The patients with AD showed an obvious decrease in Treg cell percentage,transcription factor Foxp3 mRNA level and Treg/Th17 ratio (2.01% ± 0.57% vs.5.04% ± 1.44%,t =12.47,P< 0.01; 0.65 ± 0.19 vs.1.71 ± 0.69,t=9.47,P<0.01; 1.26 ± 0.61 vs.14.53 ± 5.77,t =14.11,P < 0.01),but a significant increase in peripheral Th17 cell percentage and transcription factor RORγt mRNA level (1.77% ± 0.55% vs.0.39% ± 0.15%,t =14.82,P <0.01; 5.97 ± 1.45 vs.1.49 ± 0.57,t =17.78,P < 0.01 ) compared with the healthy controls.Further comparison revealed that Treg/Th17 ratio was significantly lower in patients with acute AD than in those with subacute AD (0.88 ± 0.04 vs.1.29 ± 0.11,t =4.02,P < 0.01 ) and those with chronic AD (2.05 ± 0.24,t =4.83,P < 0.01 ),statistically different between patients with subacute AD and chronic AD (t =2.89,P < 0.05).There was no significant difference in the serum concentration of TGF-β between patients with AD and healthy controls ((15.28 ± 2.34) μg/L vs.(16.56 ± 3.27) μg/L,t =1.96,P> 0.05).A significant increase was observed in the serum levels of IL-17 and IL-23 in patients with AD compared with those in the healthy controls( (33.24 ± 7.06)ng/L vs.(11.68 ± 2.67) ng/L,t =17.96,P< 0.01; (56.35 ± 12.16) ng/L vs.(18.43 ± 3.90) ng/L,t =18.36,P< 0.01).In patients with moderate and severe AD,SCORing atopic dermatitis (SCORAD) index was negatively correlated with the percentage of Treg ceils (r =-0.40,P< 0.05 ),but positively correlated with that of Th17 cells (r =0.42,P < 0.05 ).[Conclusion]s There exists a change in Treg/Th 17 ratio,mRN A expressions of RORγt and Foxp3,and serum levels of relevant cytokines in patients with AD,which may lead to immune imbalance and subsequently contribute to the development of AD.

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.

OBJECTIVE:To determine the equilibrium solubility of albendazole(ABZ)and its apparent oil-water partition coef-ficient. METHODS:The equilibrium solubility of ABZ in various solutions was determined at 37 ℃ by HPLC and saturation solu-bility method,including water,7 kinds of common organic solvents with different polarities(methanol,ethanol,etc.),organic ac-id(oleic acid,glacial acetic acid,lactic acid,formic acid),hydrochloric acid of pH 1.2,phosphate buffer solution(PBS)of dif-ferent pHs(2.0-7.8)and 6 kinds of common surfactants with mass concentrations of 10,50 and 100 mg/ml(polysorbate 80,polox-amer,etc.). The apparent oil-water partition coefficient(P)was calculated with the concentration ratio of ABZ in oil phase(N-oc-tyl alcohol)and water phase(water and PBS of different pHs)after partition equilibrium. RESULTS:The equilibrium solubility of ABZ reached(0.26±0.02)μg/ml in water,with the lgP of 3.66±0.01. The equilibrium solubility of ABZ in common organic sol-vents and organic acids was higher than in water. The higher the polarity of the organic solvent was and the weaker of organic acid was,the weaker of its ability to solubilize ABZ would be. The equilibrium solubility of ABZ was higher in the medium of pH 1.2-2.5 than in that of pH 5.0-7.8. The ability of the surfactant to solubilize ABZ was related to its type,and the higher of the mass concentration of the surfactant was,the stronger of its ability to solubilize ABZ became. lgP was less than 1.6 at pH 1.2-2.0 and changed little at pH 5.0-7.8 [(3.71 ± 0.26)-(3.68 ± 0.26)]. CONCLUSIONS:ABZ is insoluble in water. Its equilibrium solubility demonstrates a negative correlation with the polarity of the organic solvent and a positive correlation with the acidity of the organic acid and with the mass concentration of the surfactant. It has higher water solubility and lower lipid solubility in a strong acidic en-vironment,and higher lipid solubility and weaker water solubility in weak acidic,weak basic and neutral environments.

Objective To investigate the effect of 23.4% hypertonic saline(HTS)on intracranial pressure(ICP), cerebral peffusion pressure(CPP), cerebral blood flow(CBF)in poor-grade patients with subarachnoid hemorrhage(SAH).Methods Sixteen patients(Glasgow coma score ≤ 8)with poor-grade SAH received 23.4% hypertonic saline intravenously for elevated ICP.ICP, mean arterial pressure(MAP), CPP and the middle cerebral artery flow velocity(FV)were observed and recorded before and at 30, 60, 90,120, 150, 180 min after the injection respectively.Results Thirty minutes postinfusion, a significant increase in MAP, CPP, FV was seen together with a decrease in ICP(P<0.05).ICP remained reduced for 180 minutes, CPP and FV remained elevated for 90 minutes(P < 0.05).Conclusions HTS can significantly decrease ICP and improve CBF in patients with poor-grade subarachnoid hemorrhage and may be used for reversal of pathophysiologic changes caused by cerebral ischemia.
