[Analysis of chemical compositions in different parts of Isodon japonicus using UPLC-Q-TOF-MS technique combined with chemometrics].

In order to analyze the similarities and differences of chemical compositions between the roots and stems and leaves of Isodon japonicus(IJ), this study utilized UPLC-Q-TOF-MS technology to systematically characterize its chemical compositions, analyzed and identified the structure of its main compounds, and established a method for simultaneous determination of its content by refe-rence substance. A total of 34 major compounds in IJ, including 14 reference compounds, were identified or predicted online. Moreover, an UPLC-UV content determination method was developed for 11 compounds [danshensu, caffeic acid, vicenin-2,(1S,2S)-globoidnan B, rutin,(+)-rabdosiin,(-)-rabdosiin,(1S,2S)-rabdosiin, shimobashiric acid C, rosmarinic acid, and pedalitin].

[Quality of moxa with different leaf-to-moxa ratios based on correlation analysis of thermogravimetric properties, cellulose content, and microscopic characteristics of non-secretory trichomes].

The quality of moxa is a key factor affecting the efficacy of moxibustion. Traditional moxa grades are evaluated by the leaf-to-moxa ratio, but there is a lack of support from scientific data. Scanning electron microscopy(SEM), Image Pro Plus, Van Soest method, and stimultaneous thermal analysis(TGA/DSC) were used to characterize the scientific implication of the combustion differences between moxa with different leaf-to-moxa ratios(processed by crusher).

[Quality of moxa from Artemisia argyi and A. stolonifera in different storage years based on simultaneous thermal analysis].

The quality of moxa is an important factor affecting moxibustion therapy, and traditionally, 3-year moxa is considered optimal, although scientific data are lacking. This study focused on 1-year and 3-year moxa from Artemisia stolonifera and A. argyi(leaf-to-moxa ratio of 10∶1) as research objects.

[Thermodynamic characteristics of moxa floss and its biological effects and therapeutic mechanism on osteoarthritis rats].

Moxa floss is the main material of moxibustion, which plays a therapeutic role through the thermal effect of combustion. In this paper, TG/DSC thermal analysis method was used to study the characteristic parameters of combustion heat of moxa floss produced in Qichun, and the thermal therapeutic effect and mechanism of moxibustion were studied through moxibustion OA animal model. The results show that the combustion process of moxa floss can be divided into three stages: drying, combustion oxidation and carbonization, and ash burnout.

[Comparison of therapeutic effect of moxibustion materials from different places and storage periods on knee osteoarthritis].

Osteoarthritis(OA) is a kind of osteoarticular degenerative disease. The most common joint involvement of OA is knee and hip joint. The incidence rate of OA increases with age.

[Research progress on chemical constituents from Artemisiae Argyi Folium and their pharmacological activities and quality control].

Artemisiae Argyi Folium is a traditional medicine commonly used in traditional Chinese medicine(TCM). It contains volatile oil, flavones, phenylpropanoids, terpenes and other chemical constituents. It has the functions of antibacterial, antiviral, hemostasis, anti-tumor, liver protection, analgesic, anti-inflammatory, anti-oxidation, relieving cough and asthma and other pharmacological activities.

Isolation and characterization of a novel bacterium for biofertilizer production from kitchen waste oil.

Kitchen waste oil is composed of long chain triglycerides (LCTs) that has high energy density. However, it is hard to be degraded by microbes, thereby leading to increasing levels of environmental pollution due to landfill disposition. In this study, we isolated and characterized a novel bacterium PA-3 that could convert kitchen waste oil into biofertilizer.

Protective effect of epimedium combined with oligomeric proanthocyanidins on exercise-induced renal ischemia-reperfusion injury of rats.

Objective: This paper studied the protective effect and mechanism of epimedium combined with oligomeric proanthocyanidins on exercise-induced renal ischemia-reperfusion injury of rats.

Methods: In the experiment, the rats were given exhaustive swimming training and then their blood urea nitrogen (BUN) and other biochemical indexes were measured after they were given gastric perfusion with 6.01 g/kg doze of epimedium and 50 mg/kg doze of oligomeric proanthocyanidins for 56 days.

The effect of loaded deep inhale training on mild and moderate COPD smokers.

Objective: To research the therapeutic effect of loaded deep inhale training on mild and moderate COPD smokers.

Design: 30 mild and moderate COPD smokers were divided into the observation group and the control group at random. The observation group underwent loaded deep inhale training in the morning and in the evening twice for 30 minutes each time for 3 months.
