摘要：
Biochar materials have attracted people’s attention because of their environmental friendliness, abundant resources, and the use of waste resources for reuse. As a potassium-ion anode material, biomass char materials synthesized by different methods have broad application prospects. However, due to the problems of low initial magnification and limited potassium-storage capacity, it is necessary to improve the electrochemical performance through modifications, such as atomic doping. Atomic doping is an effective way to improve battery conductivity and potassium storage. In this paper, the synthesis method of biochar as an anode material for potassium-ion batteries and the influence of atomic doping on its modification in recent years are reviewed.
摘要：
Epidemic obesity is contributing to increases in the prevalence of obesity-related metabolic diseases and has, therefore, become an important public health problem. Adipose tissue is a vital energy storage organ that regulates whole-body energy metabolism. Triglyceride degradation in adipocytes is called lipolysis. It is closely tied to obesity and the metabolic disorders associated with it. Various natural products such as flavonoids, alkaloids, and terpenoids regulate lipolysis and can promote weight loss or improve obesity-related metabolic conditions. It is important to identify the specific secondary metabolites that are most effective at reducing weight and the health risks associated with obesity and lipolysis regulation. The aims of this review were to identify, categorize, and clarify the modes of action of a wide diversity of plant secondary metabolites that have demonstrated prophylactic and therapeutic efficacy against obesity by regulating lipolysis. The present review explores the regulatory mechanisms of lipolysis and summarizes the effects and modes of action of various natural products on this process. We propose that the discovery and development of natural product-based lipolysis regulators could diminish the risks associated with obesity and certain metabolic conditions.

Abstract: Objective: To establish a method for the simultaneous determination of seven alkaloids in Semen Nelumbinis and its products, the extraction technology and HPLC method were optimized by the single factor experiment. Methods: Firstly, the samples were extracted ultrasonically with 1% formic acid ethanol and purified by PXC SPE column. Then, the extracts and the purified liquid were taken after concentration with nitrogen for quantitative analysis of seven alkaloids by HPLC method. Next, the contents of alkaloids in five samples were determined. Results: The method was fully validated and the result showed that seven kinds of alkaloids had good linear relation in the corresponding range of mass concentration, r2 > 0.999, where the detection limit was 0.5–1.5 mg/kg, the quantification limit was 1.25–4.5 mg/kg, the recovery was 83.33–116.04%, and the RSD of detection method was 1.06–5.25% (n = 7). In five samples, the contents of Lotusine and Neferine were the highest, Berberine Hydrochloride was not detected. Conclusion: This method is simple, sensitive, accurate and reproducible, and it can realize the quantitative analysis and chemical separation of seven kinds of common alkaloids in Semen Nelumbinis and its products and provide a theoretical method for the simultaneous determination of alkaloids. The extraction yields of alkaloids in Semen Nelumbinis can be increased through the extraction process, which is optimized by a single factor experiment.

摘要：
Introduction: Whether acupuncture is efficacious for patients with functional dyspepsia is still controversial. So we designed a randomised controlled trial to settle the problem. Methods and analysis: We designed a multicentre, two-arm, sham-controlled clinical trial. 200 participants with functional dyspepsia will be randomly assigned to the true acupuncture (TA) group and sham acupuncture (SA) group in a 1:1 ratio. Participants in the TA group will receive acupuncture at points selected according to syndrome differentiation. Participants in the sham acupuncture group will receive penetrations at sham points. Participants in both groups will receive 20 sessions of electroacupuncture in 4 weeks, five times continuously with a 2 day rest in a week. The primary outcome is the proportion of patients reporting the absence of dyspeptic symptoms at 16 weeks after inclusion. The secondary outcome includes a Short- Form Leeds Dyspepsia Questionnaire, the Chinese version of the 36-Item Short Form Survey, the Chinese version of the Nepean dyspepsia index, etc. Ethics and dissemination: The study protocol has been approved by the institutional review boards and ethics committees of the first affiliated hospital of Chengdu University of TCM, the first affiliated hospital of Hunan University of TCM and Chongqing Medical University, respectively (from April to August 2012). The results of this trial will be disseminated in a peerreviewed journal and presented at international congresses.
摘要：
The series piezoelectric quartz crystal (SPQC) sensing technique is a rapid and sensitive method for detection of microorganisms. In the present study, the detection device was composed of detecting system, signal generating system and data analyzing system. To magnify the amount of detection samples, eight independent SPQC sensors were parallel connected to form a muti-channel detecting unit. Electrodes were separated from the SPQC sensor and immersed into culture medium to detect the change of solution conductivity. The cell constant k was determined as 0.05 m, and the sensitivity interval of the device was from 550 to 600 μs. To maintain sensitivity of the SPQC sensor, a novel culture medium amino acid broth (AaB) was developed. It was nutrient with low conductivity and satisfied our detection device. For determining frequency detection time (FDT) expediently and accurately, FDT was defined afresh with fitting–differentiating method. Pathogens Staphylococcus aureus and Shigella dysenteriae were determined with an automated detecting device and the methods mentioned above. The calibration curves of FDT against density of bacteria showed a linear correlation coefficient (R ≥ 0.99) over the range of 10–106 cells ml−1. Detection results all fell inside the 95% confidence interval of a standard pour plate counting method. The reproducibility was also reviewed, and results showed that the device was stable and sensitive even after 180 days of employment.
