In this study, infrared spectroscopy, high-performance liquid chromatography, and matrix-assisted laser desorption ionization-time-of-flight-mass spectrometry (MALDI-TOF-MS) technology were applied to systematically explain the Schisandra chinensis's polysaccharide transformation in configuration, molecular weight, monosaccharide composition, and anti-ulcerative colitis (UC) activity after vinegar processing. Scanning electron microscopic results showed that the appearance of S. chinensis polysaccharide changed significantly after steaming with vinegar.

Glioma is one of the most common types of brain tumors, and its high recurrence and mortality rates threaten human health. In 2008, the frequent isocitrate dehydrogenase 1 (IDH1) mutations in glioma were reported, which brought a new strategy in the treatment of this challenging disease. In this perspective, we first discuss the possible gliomagenesis after IDH1 mutations (mIDH1).

The eukaryotic ribosome is essential for cancer cell survival. Perturbation of ribosome biogenesis induces nucleolar stress or ribosomal stress, which restrains cancer growth, as rapidly proliferating cancer cells need more active ribosome biogenesis. In this study, we found that UTP11 plays an important role in the biosynthesis of 18S ribosomal RNAs (rRNA) by binding to the pre-rRNA processing factor, MPP10.

Since the current identification method for Paeoniae Radix Alba is complex in operation and long time-consuming with high requirements for technicians, the present study employed Heracles NEO ultra-fast gas phase electronic nose(E-nose) technology to identify raw and sulfur-fumigated Paeoniae Radix Alba decoction pieces in order to establish a rapid identification method for sulfur-fumigated Paeoniae Radix Alba. The odors of raw Paeoniae Radix Alba and its sulfur-fumigated products were analyzed by Heracles NEO ultra-fast gas phase E-nose to obtain the odor chromatographic information. The chemometric model was established, and the data were processed by principal component analysis(PCA), discriminant function analysis(DFA), soft independent modeling of class analogy(SIMCA), and partial least squares discriminant analysis(PLS-DA).

Based on UPLC characteristic chromatogram and quantitative analysis of multi-components by single marker(QAMS), the content of seven types of ginsenosides in Ginseng Radix et Rhizoma was simultaneously determined, and the quality of Ginseng Radix et Rhizoma was evaluated by the principal component analysis(PCA). The chromatographic separation was performed on the Acquity UPLC BEH C_(18) column(2.1 mm×100 mm, 1.

Intravenous leiomyomatosis (IVL) is a rare form of gynaecological- uterine leiomyoma. Clinically, the diagnosis and treatment are more difficult and challenging due to occult symptoms and clinical presentations, which can be similar to other common diseases. In this report, comprehensive management of a case of IVL is reported and discussed, with the aim of sharing our academic and clinical experience to improve the medical management of IVL.

Purpose: Thyroid hormone withdrawal (THW) inevitably induced hypothyroidism in patients with differentiated thyroid cancer (DTC), and we aimed to evaluate the safety and efficacy of a novel recombinant human thyroid-stimulating hormone (rhTSH, ZGrhTSH) as an alternative of THW in China.

Methods: Totally, 64 DTC patients were enrolled with 24 in the dose-escalation cohort equally grouped into 0.9 mg × 1 day, 0.

The methods for determining the characteristic chromatogram and index components content of Xuanfu Daizhe Decoction were established to provide a scientific basis for the quality evaluation of substance benchmarks and preparations. Eighteen batches of Xuanfu Daizhe Decoction were prepared with the decoction pieces of different batches and of the same batch were prepared respectively, and the HPLC characteristic chromatograms of these samples were established. The similarities of the chromatographic fingerprints were analyzed.

Background: To identify the association between tricuspid annular circumference and secondary tricuspid regurgitation and analyze the risk factors of recurrent tricuspid regurgitation after concomitant tricuspid annuloplasty during left heart surgery.

Methods: From October 2018 to June 2019, a total of 117 patients receiving concomitant tricuspid annuloplasty within left heart surgery were enrolled. Severity of tricuspid regurgitation was classified as 4 subtypes: normal, mild, moderate and severe.

Article Synopsis
  • The quality control of Zhuru Decoction was conducted using fingerprinting and network pharmacology to predict efficacy-related substances.
  • 25 common peaks were identified in the decoction, including key components like puerarin and glycyrrhizic acid, all showing a high similarity index.
  • A network analysis revealed 9 active chemical components linked to pathways involved in energy metabolism and alleviating symptoms like nausea, suggesting these could be important for the decoction's efficacy and quality control.

Totally 21 batches of Gastrodiae Rhizoma pieces from various habitats with different appearance characteristics were analyzed. Five active components( gastrodin,4-hydroxybenzyl alcohol,parishin B,parishin C,and parishin A) were determined by UPLC. Polysaccharide content was determined by phenol sulfuric acid method.

Both raw and vinegar products of the rhizome of Curcuma phaeocaulis are common drugs for promoting blood circulation and removing blood stasis in traditional Chinese medicine,which could be reflected in the inhibition of tail thrombosis in mice. As the traditional processing theory instructs,vinegar tastes sour and bitter,but can activate blood circulation and remove stasis after being infiltrated into the rhizome of C. phaeocaulis as an excipient.

Sulfur fumigation method is often used in the habitat processing of Astragali Radix in order to make it mothproof, mildewproof and easy to dry; however, this method has great influence on the inherent quality of Astragali Radix. Therefore, it is urgent to develop the alternative technology to sulfur fumigation. In the present paper, appearance characteristics, content of active ingredients, containing water, extracting content and microbial content in Astragali Radix were taken as the indexes to compare the quality of Astragali Radix processed with 9 kinds of processing methods (traditional processing method, sulfur fumigation and 7 kinds of alternative processing technologies).

Cyanobacteriochromes are a structurally and spectrally highly diverse class of phytochrome-related photosensory biliproteins. They contain one or more GAF domains that bind phycocyanobilin (PCB) autocatalytically; some of these proteins are also capable of further modifying PCB to phycoviolobilin or rubins. We tested the chromophorylation with the non-photochromic phycoerythrobilin (PEB) of 16 cyanobacteriochrome GAFs from Nostoc sp.

Hashimoto's thyroiditis (HT) is a autoimmune disease that is highly incident year by year. Its clinical manifestations are alternative hyperthyroidism or hypothyroidism, relatively high Th1, excessively low Th2 and constantly increasing TGAb and TMAB. Currently, the disease is still difficult to be cured, and instable thyroid function makes it harder to be treated.

Objective: To compare the change of the content of cantharidin in Mylabris before and after biotransformation.

Methods: The content of cantharidin was determined by gas chromatography (GC). The conditions of GC were as follows: HP-5 column, vanillin as internal standard, the column temperature maintained at 175 degrees for 5 min, rised to 240 degrees C at the speed of 4 degrees C/min and the remained for 5 min.
