[Systematic review of xiyanping injection for hand foot mouth disease].

To assess the efficacy and safety of Xiyanping injection for hand foot mouth disease. All Clinical studies of Xiyanping injection for hand foot mouth disease were searched from Cochrane library, Medline, EMbase, CBM, CNKI, Wanfang and VIP. Selection of trials for inclusion, data extraction, assessment of methodological quality were completed by two independent screening. The quality of the included documents was evaluated by the Cochrane collaboration's tool for assessing risk of bias and allocation concealment. Revman 5. 1 software was used for data analysis. Twenty-four randomized controlled trials were included (involving 2 974 patients), in which, only one study was true RCT and two studies used incorrect methodology. The remaining studies did not provide allocation concealment, blind or loss-up information. The results of Meta-analysis were presented below. Compared with conventional treatment measures, the efficiency of Xinyanping injection group was better (OR = 4.26, 95% Cl [3.19, 5.69]). Both fever clearance time (WMD = - 1.48, 95% Cl [- 1.85, - 1.11]) and skin eruption eliminating time (WMD = - 1.78, 95% Cl [- 2.84, - 0.72]) of Xinyanping injection group were shorter than the control group. Researches with ADR/AE information of Xinyanping injection showed that the symptoms of ADR/AE were slight. The systematic review suggests that Xiyanping injection in the combination with conventional treatment may improve the efficacy of the treatment of hand foot mouth disease. However, as all of the included trials were published in Chinese and of poor quality, we cannot draw a sure conclusion. More rigorous trials with high quality are required.

A review of physiological functions of orexin: From instinctive responses to subjective cognition.

Orexin, also known as hypocretin, is an excitatory neuropeptide secreted by the hypothalamus. Orexin is divided into orexin-A (OXA) and orexin-B (OXB), which are derived from a common precursor secreted by hypothalamic neurons. Orexin acts on orexin receptor-1 (OX1R) and orexin receptor-2 (OX2R). Orexin neurons, as well as receptors, are widely distributed in various regions of the brain as well as in the peripheral system and have a wider range of functions. This paper reviews the latest research results of orexin in the aspects of food intake, sleep, addiction, depression and anxiety. Because orexin has certain physiological functions in many systems, we further explored the possibility of orexin as a new target for the treatment of bulimia, anorexia nervosa, insomnia, lethargy, anxiety and depression. It is precisely because orexin has physiological functions in multiple systems that orexin, as a new target for the treatment of the above diseases, has potential contradictions. For example, it promotes the function of 1 system and may inhibit the function of another system. How to study a new drug, which can not only treat the diseases of this system, but also do not affect other system functions, is what we need to focus on.

Chinese Medicinal Leech: Ethnopharmacology, Phytochemistry, and Pharmacological Activities.

Hirudo (Shuizhi in Chinese) is an important Chinese medicine, which possesses many therapeutic properties for the treatment of the cerebral hemorrhage and other thrombosis-related diseases. The phytochemical investigation gave more than 51 compounds including pteridines, phosphatidylcholines, glycosphingolipids, and sterols, as well as some bioactive peptides from the Shuizhi derived from three animal species recorded in the current Chinese Pharmacopoeia. The pharmacological studies on the Shuizhi have revealed various activities such as anticoagulation, antithrombosis, antiatherosclerosis, antiplatelet aggregation, antitumor and anti-inflammatory as well as hemorheology improvement, and protective effects against cerebral ischemia-reperfusion injury. However, some important issues based on the traditional uses of Shuizhi are still not clear. The aim of the present review is to provide comprehensive knowledge on the ethnopharmacology, phytochemistry, and pharmacological activities of Shuizhi. It will provide a potential guidance in exploring main active compounds of Shuizhi and interpreting the action mechanism for the further research.

Identification of antibacterial and antioxidant constituents of the essential oils of Cynanchum chinense and Ligustrum compactum.

The aim of this research was to determine the chemical composition, antioxidant and antibacterial properties of the essential oils from Cynanchum chinense and Ligustrum compactum and isolation of antioxidant and antibacterial constituents from the essential oils. Thirty-eight components were identified in essential oils. Based on bioactivity-guided fractionation, guaiacol, linalool and 2-phenylethanol were isolated and identified as active constituents. Both L. compactum flower oil and 2-phenylethanol showed high antibacterial performance, with inhibition zone from 22.8 ± 0.8 to 11.9 ± 2.0 mm at highest concentration, and minimum inhibitory concentration values ranging from 0.25% to 1%. In both DPPH and ABTS assay, the active constituent guaiacol (IC50 = 4.15 ± 0.72 and 9.12 ± 0.98 µg mL(-1), respectively) exhibited high antioxidant activity, and the oils showed moderate antioxidant activity. These results indicate potential efficacy of active constituents and essential oils of L. compactum and C. chinense to control food-borne pathogenic and spoilage bacteria.
