Commonly adulterated affecting mostly metabolic and sexual dysfunction drugs. Control quality of those phytomedicines requires development of strategy and techniques applicable to them. Among the techniques, Reverse Phase Liquid Chromatography is the most used and has been developed in these studies to assess a protocol to characterize Gardenia aqualla leaves extract. The method consists in determining chromatographic conditions using organic and pH gradient models based on water and acetonitrile combined with pH modifiers made up of formic acid (AF) and ammonium hydroxide (NH<sub>3</sub>). Results show that extracts contain mainly acidic compounds quickly eluted by NH<sub>3</sub> and more retained by AF. Optimal pH range for separation is 3 - 7 corresponding to 1.59 mM of NH<sub>3</sub> and 6.55 mM of AF. In these conditions, elution of many polar compounds could be effective using a C18 based-deactivated column in a short period of time.展开更多

Baseline separation was achieved on an XTerra C18 column（5 μm, 250 mm×4.6 mm i. d.） with linear gradient elution of formate buffer（consisting of 0.5% formic acid, adjusted to pH=4.5 with ammonia） and acetonitrile（consisting of 0.2% formic acid and 0.2% triethylamine）. The me- thod was validated for linearity（r^2〉0.9995）, repeatability（RSD〈3.1%）, intra- and inter-day precision（RSD〈1.8%） with recovery（99.9%-105.1%）, limits of detection（0.15-0.35 μg/mL）, and limits of quantification（0.53-0.82 μg/mL）. The similarities of 32 batches of Rhizoma Coptidis and their classification according to their manufacturers were based on the retention time and peak areas of the characteristic compounds. The five compounds were selected for quality assessment ofRhizoma coptidis via partial least squares analysis（PLS）.展开更多

Waters OASIS HLB was used for concentrating and purifying samples and Alltima C18（53 mm×7 mm, 3 μm） chromatography column was used for separating ginsenoside Rg1, Re, Rb1, Rc, Rb2 and Rd. These ginsenosides were analyzed within 20 min in our gradient elution process and the equilibrium time of the chromatography column cost only 5 min. Moreover, there was no obvious baseline drift in our experiment. This method was used to analyze the contents of ginsenosides in different ginseng products for quality control. Four ginseng products were studied, including two kinds of capsules, one kind of tablet and one kind of injection. The results show that the method developed in this paper had good accuracy, linearity and precision. Therefore, this method could be applied in quality control of ginseng products.展开更多

However, bioinformatic characteristics and potential functions of PDIs in diatom Phaeodactylumtricornutum (Pt) are still unknown so far. Hence, the genome-wide characteristics of PtPDI proteins in P. tricornutumwere first studied via bioinformatic and transcriptomic methods. 42 PtPDI genes were identified from thegenome of P. tricornutum. The motif, protein structure, classification, number of introns, phylogenetic relationship,and the expression level of 42 PtPDI genes under the tunicamycin stress were analyzed. A pair of tandemduplicated genes (PtPDI15 and PtPDI18) was observed in P. tricornutum. The 42 PtPDIs with different genecharacteristics were divided into three independent clades, indicating different evolutional relationships and functionsof these PtPDIs. The 14 up-regulated PtPDI genes under the tunicamycin treatment might have a positiveeffect on the ER quality control of the unfolded/misfolded proteins, while the 7 down-regulated PtPDIs mightnegatively affect the ERQC. The characteristics of all 42 PtPDIs and their proposed working model here providea comprehensive understanding of the PtPDIs gene family. The differential expression of 21 PtPDIs will be usefulfor further functional study in the ERQC.展开更多

文摘Background:Good adherence to post-operative exercise is crucial for long-term exercise intervention programs aimed at improving compliance,motivation for functional exercise,and quality of life among breast cancer patients.This study aims to evaluate the application effect of quality control circles on postoperative functional exercise compliance in breast neoplasm patients.Methods:A comprehensive search was conducted in CNKI,Wanfang,VIP,CBM,PubMed,Cochrane Library,Web of Science and CINAHL databases from their establishment to May 06,2023.Manual search and backtracking of relevant literature were also conducted.The search terms included a combination of subject terms and free words.Meta-analysis was performed using RevMan 5.4 software on eligible literature.Results:Initially,517 papers were retrieved,and after removing duplicates 238 papers using NoteExpress software,279 titles and abstracts were reviewed.Subsequently,225 non-compliant papers were excluded,leaving 54 full texts to be read.After excluding 38 non-compliant papers,16 eligible papers were included for Meta-analysis.These papers comprised a total of 1,342 patients(679 in the test group and 663 in the control group).The heterogeneity test using a fixed effects model showed P=0.22 and I2=21%.The Meta-analysis results demonstrated that the implementation of quality control circles alongside usual care significantly improved compliance with postoperative functional exercise in breast cancer patients(odds ratio=6.68,95%confidence interval(4.97,8.98),P<0.00001).Conclusion:Quality control circles activities can effectively enhance compliance with post-operative functional exercise among breast cancer patients,aiding in the recovery of affected limb function,improvement of self-care ability,and early reintegration into society and normal life,thereby enhancing quality of life.It is important to continually accumulate experience in applying relevant quality control circles activities in clinical work and promptly enhance the level of care accordingly,as the functional exercise of breast cancer patients after surgery involves a long-term and gradual improvement process.
