Exploring the mechanism of Qinbaiqingfei-concentrate pills in the treatment of Mycoplasma pneumoniae pneumonia from the perspective of intestinal microbiota and mucosal immunity.

Ethnopharmacological Relevance: Traditional Chinese medicine categorizes Mycoplasma pneumoniae pneumonia as "lung heat", and treatment with heat clear and detoxify. Traditional Chinese medicine believes that the lungs and intestines come from the same source, and the intestine is related to pneumonia. This is the same as the gut-lung axis theory.

A Study Based on Metabolomics, Network Pharmacology, and Experimental Verification to Explore the Mechanism of Qinbaiqingfei Concentrated Pills in the treatment of Mycoplasma Pneumonia.

Qinbaiqingfei concentrated pills (QB) are a commonly used medicine for the treatment of mycoplasma pneumonia in China, and the mechanism of action of QB needs to be studied further. Therefore, we use a combination of metabolomics and network pharmacology to clarify the mechanism of QB. Nontarget metabolomics studies were performed on rat serum, urine, and lung tissues, and 56 therapeutic biomarkers were found.

[Analysis of chemical constituents of Ginseng-Douchi compound fermentation products based on UPLC-Q-TOF-MS].

In this experiment, ultra high performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to analyze and identify chemical constituents of Ginseng-Douchi(GD) compound fermentation, and explore the conversion rules of ginsenosides and soybean isoflavones after compound fermentation. Waters Acquity UPLC BEH C_(18) column(2.1 mm×100 mm, 1.

Incidence and radiological pattern of eosinophilic granuloma: a retrospective study in a Chinese tertiary hospital.

Background: The incidence and radiological patterns of eosinophilic granuloma (EG) in China is not clear. We described the incidence, presentation, and imaging characteristics of Chinese EG patients in a tertiary hospital.

Methods: A retrospective chart review was performed from January 2004 to October 2017 at a single tertiary general hospital.

Incidence and clinical variable inter-relationships of thymic epithelial tumors in northwest China.

Background: Thymic epithelial tumors (TETs) are the most common primary thymus tumors, but neither the possible ethnical/regional differences in the incidence of TETs nor the inter-relationships among the clinical variables has been revealed in northwest China.

Methods: A retrospective chart review was performed among pathologically confirmed TET patients from January 2004 to December 2015 in a tertiary general hospital of northwest China and the incidence, clinical features and the inter-relationships among clinical variables were analyzed.

Results: A total of 603 pathologically confirmed TETs patients (age range, 5-78 years; 308 males) were enrolled and the most common lesion location was anterior mediastinum (98.

Identification and characterization of major constituents in Juglans mandshurica using ultra performance liquid chromatography coupled with time-of-flight mass spectrometry (UPLC-ESI-Q-TOF/MS).

The present study was designed to identify and characterize the major constituents in Juglans mandshurica Maxim. A simple, efficient and sensitive ultra performance liquid chromatography coupled with time-of-flight mass spectrometry (UPLC-ESI-Q-TOF/MS) method was established and validated under positive and negative ion modes. The separation was performed on a Waters ACQUITY UPLC BEH C column (2.

[Dynamic variation of major effective components in fresh rejuvenated fruit of Juglans mandshurica based on UPLC-Q-TOF-MS].

The changes in effective components of Juglans mandshurica at different harvest periods were analyzed by UPLC-Q-TOF-MS/MS. Eighteen batch samples of J. mandshurica from six harvest periods were assessed by multivariate statistical analysis with Markerview software.

[Therapeutic Material Basis of Chemical Subdivisions of Anemarrhenae Rhizoma on Anti-inflammatory and Immunomudulatory Effects].

Objective: To study the relationship between chemical subdivision and immune suppressive activity in order to find out the anti-inflammatory and immunomudulatory pharmacological activity material basic of Anemarrhenae Rhizoma.

Method: C57 mice was induced by 2,4-Dinitrofluorobenzene to build immune inflammation which was also called contact allergic dermatitis. The influence of Anemarrhenae Rhizoma decoction and chemical subdivisions on immune organ, ear edema and the Th1/Th2 immune balance was measured by analytical balance and Elisa method.
