[Composition changes reveal relationship between color and enzymatic reaction of Magnoliae Officinalis Cortex during "sweating" process].

In this study, we employed Q Exactive to determine the main differential metabolites of Magnoliae Officinalis Cortex du-ring the "sweating" process. Further, we quantified the color parameters and determined the activities of polyphenol oxidase(PPO), peroxidase(POD), and tyrosinase of Magnoliae Officinalis Cortex during the "sweating" process. Gray correlation analysis was performed for the color, chemical composition, and enzyme activity to reveal the effect of enzymatic reaction on the color of Magnoliae Officinalis Cortex during the "sweating" process.

The clinicopathological and prognostic value of the pretreatment neutrophil-to-lymphocyte ratio in small cell lung cancer: A meta-analysis.

Although many scholars have recently studied the relationships between the pretreatment neutrophil-to-lymphocyte ratio (NLR) and prognosis in patients with small cell lung cancer (SCLC), the conclusions have been inconsistent. Accordingly, in this meta-analysis, we attempted to assess the clinicopathological and prognostic value of the pretreatment NLR in SCLC. Related literature was searched using PubMed, Embase, Cochrane Library, Web of Science, Chinese Biomedical Literature, China National Knowledge Infrastructure (CNKI), and Wanfang databases.

[Microbial community diversity and its characteristics in Magnolia Officinalis Cortex "sweating" process based on high-throughput sequencing].

Magnolia Officinalis Cortex has been used as a traditional Chinese herb for thousands of years in China. According to Chinese Pharmacopoeia,the processing of Magnolia Officinalis Cortex needs " sweating" or " Fahan",which was a special drying process and considered to be an important symbol for high quality and genuine medicinal materials. In this unique processing mode,Magnolia Officinalis Cortex's microbial community structure may be changed,but little is known about microbial diversity during the " sweating".

The association of D-dimer with clinicopathological features of breast cancer and its usefulness in differential diagnosis: A systematic review and meta-analysis.

Background: Studies have shown that D-dimer levels are significantly correlated with the differential diagnosis and clinicopathological features of breast cancer. However, the results are currently limited and controversial. Therefore, we performed this meta-analysis to evaluate the relationship between D-dimer levels and breast cancer.

[Correlation between accumulation of flavoneand expression of functional genes in Carthamus tinctorius].

The average yield of safflower blooming from 1 to 7 day was recorded and calculated, HPLC was used to detect the percentage composition of HYSA,quercetin,naringenin and kaempferol, and the real-time PCR was used to analyze the expression of chs and chi. The average yield,percentage composition of HYSA and naringenin as well as functional genes' expression presented similar trends. The average yield reached the highest peak at the third day, showing highpositive correlation with the contents of HYSA (r=0.

[Safflower's origin and changes of producing areas].

Human's application of safflower (Carthamus tinctorius) has a long history, but the origin remains unclear. Safflower was introduced into China for traditional Chinese medicine, and Sichuan was major producing area. However, in recent years, the main producing area is in Xinjiang province, in contrast Sichuan safflower is difficult to find.

[Cloning,Bioinformatic Analysis of Chalcone-Flavonone Isomerase Gene( CHI) and Relationship Between Expression of CHI and Accumulation of HSYA in Carthamus tinctorius].

Objective: To clone chalcone-flavonone isomerase( CHI) gene in Carthamus tinctorius,to analyze the bioinformation of CHI,to compare the expression of CHI,and to analyze the percentage composition of hydroxysafflor yellow A( HSYA) during the florescence,in order to provide the foundation for functional verification of CHI and the composition and regulation mechanism of the flavonoid constituents in Carthamus tinctorius.

Methods: CHI was cloned,bioinformatics was used to analyze the protein characteristics, real timePCR was used to analyze the expression of CHI,and HPLC was used to analyze the percentage composition of HSYA

Results: A 696 bp CHI sequence in Carthamus tinctorius,the expression of CHI and the percentage composition of HSYA during the florescence were obtained. The variation tendency was similar between the expression of CHI and the accumulation of HSYA, which was increased gradually during 1 ~ 4 d and peaked at the fourth day,then decreased sharply during the fifth to the seventh day of florescence.
