A quantitative chemomics strategy for the comprehensive comparison of Murraya paniculata and M. exotica using liquid chromatography coupled with mass spectrometry. J Chromatogr A 2024; 1718:464736. [PMID: 38364618 DOI: 10.1016/j.chroma.2024.464736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 02/03/2024] [Accepted: 02/11/2024] [Indexed: 02/18/2024]
Abstract
Murrayae Folium et Cacumen (MFC) is a traditional Chinese medicine (TCM) derived from two plant species, Murraya exotica L. and Murraya paniculata (L.) Jack, as recorded in the Chinese Pharmacopoeia. However, there is no research available on the comprehensive analysis and comparison of the chemical constituents of these two species. In the present study, an integrated LC-MS-based quantitative metabolome strategy was proposed to conduct a comprehensive and in-depth qualitative and quantitative analysis and comparison of the chemome of M. exotica and M. paniculata. Firstly, the universal chemical information of two plants was obtained by quadrupole-time-of-flight mass spectrometry (Q-TOF-MS) combined with hybrid triple quadrupole-linear ion trap mass spectrometry (Qtrap-MS). Subsequently, a UNIFI in house database, the proposed fragmentation patterns, and a quantitative structure chromatographic retention relationship (QSRR) model were integrated for the rapid, comprehensive, and accurate structural elucidation of the chemical constituents of these two species. Thirdly, a large-scale quantitation method was established using scheduled multiple reaction monitoring mode (sMRM) and 76 primary components were selected as quantitative markers for the method validation. The obtained dataset was then subjected for multivariate statistical analysis to comprehensive comparison of these two plants. As a result, a total of 209 and 212 compounds were identified from M. exotica and M. paniculata, respectively. Among them, 103 common constituents were disclosed in both plants. The multivariate statistical analysis and absolute quantitative analysis revealed noticeable differences in the contents of specific chemical constituents between these two plants. The higher quantity constituents in M. exotica are 7-methoxycoumarins, while polymethoxylated flavonoids are the major constituents in M. paniculata. The common compounds accounted for approximately 80 % of the quantitative components in both plants, which provides a theoretical basis for their common use as the official source of MFC. In sum, the established quantitative chemomics strategy supplies an effective means for comprehensive chemical comparison of multi-source TCMs.

Abstract
Cardiac surgery can provoke an acute cytokine storm that may contribute to the development of postoperative multiple organ dysfunction syndrome. We prospectively observed patients undergoing cardiac surgery and divided them into two groups: the severe group and the mild group. Healthy individuals were enrolled acting as the control group for comparison. Plasma samples and clinical data were recorded at the initiation of cardiac-pulmonary bypass (CPB) and 3, 6, 12, 24, and 48 h after initiation of CPB. Cytokine levels were detected using the Luminex® technique. Thirty-nine adults were enrolled in this study (14 in the severe group, 15 in the mild group, and 10 in the control group). Cytokine concentrations were significantly higher in the severe group. Principal component analysis was used to establish a cytokine storm intensity curve, which represented the overall trend of 10 cytokines. The peak concentrations of interleukin (IL)-6, IL-10, and IL-16 were 425.1, 198.5, and 623.0 pg/mL, which were more than 1,200, 1,800, and 240 times the normal level, respectively. The maximum cytokine storm intensity predated the maximum Vasoactive-Inotropic Score (VIS) and Sequential Organ Failure Assessment (SOFA) score in the severe group. Cytokine storm response to cardiac surgery occurred early and was associated with disease severity. Interventions to cytokine storm should be initiated early as guided by cytokine storm biomarkers such as IL-6, IL-10, and IL-16 in severe patients undergoing cardiac surgery. Clinical Trial Registration: ChiCTR1900021351.

Tian J, Zhang H. Effect of bone cement-reinforced pedicle screws combined with fusion repositioning therapy on lumbar spine function and postoperative complications in patients with severe lumbar spondylolisthesis. Contemp Clin Trials Commun 2023; 33:101156. [PMID: 37323938 PMCID: PMC10265474 DOI: 10.1016/j.conctc.2023.101156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 05/05/2023] [Accepted: 05/27/2023] [Indexed: 06/17/2023] Open
Abstract
Objective To retrospectively study the efficacy of bone cement-enhanced pedicle screws combined with interbody fusion reduction in the treatment of severe lumbar spondylolisthesis, its effect on lumbar function and complications. Methods From January 2019 to June 2021, 82 cases of severe lumbar spondylolisthesis in our hospital were analyzed. According to the different treatment plans, the patients were divided into two groups: A and B, in which group A patients were treated with pedicle screws combined with fusion and reduction, and group B patients were treated with bone cement reinforced pedicle screws combined with fusion and reduction. Perioperative indexes, pain severity (VAS), Oswestry dysfunction index (ODI), and low back and leg pain score of Japan Orthopedic Association (JOA), spondylolisthesis reduction, intervertebral space height, intervertebral foramen height, complications, and screw loosening were compared between the two groups. Results There was no significant difference in the amount of intraoperative bleeding between group A and group B (P > 0.05). The operation time of group B was longer than that of group A, and the hospitalization time was shorter than that of group A. The vertebral fusion rate of group B was higher than that of group A (P < 0.05). The VAS, ODI and JOA scores at the last follow-up in both groups were lower than those before surgery, and group B was lower than group A (P < 0.05). Compared with the preoperative period, the postoperative slippage degree grading improved in both groups, while the improvement rate in group B was higher than that in group A (P < 0.05). At the last follow-up, the scores of intervertebral foramen height and intervertebral space height in both groups were higher than those before operation, and those in group B were higher than those in group A (P < 0.05). There was no difference in the incidence of complications and screw loosening between the two groups (P > 0.05). Conclusion Compared with conventional screw treatment, bone cement-reinforced pedicle screws combined with fusion repositioning can further improve the repositioning rate of slipped vertebrae in the treatment of severe LSL, while achieving a better intervertebral fusion rate. Therefore, the treatment of severe LSL with bone cement reinforced pedicle fusion and reduction is a safe and effective method.

Abstract
Panax ginseng can be generally divided into mountain-cultivated ginseng (MCG) and garden-cultivated ginseng (GCG). The market price of MCG is significantly higher than that of GCG. However, the chemical compositions of MCG and the differences from GCG remained unclear. In this study, an integrated strategy combing an offline two-dimensional liquid chromatography separation, LTQ-orbitrap dual mode acquisition, and Q-trap full quantification/quasi-quantification was proposed to explore and compare the chemical compositions of MCG. Consequently, 559 ginsenosides were characterized, among which 437 ginsenosides were in-depth characterized with α-chain and β-chain annotated. Subsequently, enhanced quantification of 213 ginsenosides was conducted in 57 batches of MCG and GCG. Ginsenosides were found more abundant in MCG than GCG. In addition, 25-year-old MCG could be distinctly differentiated from 15/20-year-old MCG. This strategy facilitated the enhanced profiling and comparison of ginsenosides, improved the quality control tactics of MCG and provided a reference approach for other ginseng related products.

Metabolomic study combined with the low-level light therapy of Chinese acupuncture points and combined oral contraceptives in treatment of primary dysmenorrhea: A prospective, multicenter, randomized controlled study. Heliyon 2023; 9:e13821. [PMID: 36915513 PMCID: PMC10006448 DOI: 10.1016/j.heliyon.2023.e13821] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 02/10/2023] [Accepted: 02/13/2023] [Indexed: 02/18/2023] Open
Abstract
Objective To compare the changes of metabolites between Low-level light therapy (LLLT) and combined oral contraceptive (COC) after treatment of primary dysmenorrhea (PD), and to compare and analyze the biological and biochemical effects of the two treatments by analyzing the differences in metabolite profiles. Methods A multicenter, double-blind, prospective, parallel, randomized controlled study was conducted on 69 women aged 16-35 years old with PD who were randomly divided into COC treatment group or LLLT treatment group. Low-level light therapy with light-emitting diodes (LED) was applied on two acupoints named "Guanyuan" (CV4) and "Qihai" (CV6). After 12 weeks of treatment intervention, blood samples were collected before and after treatment for metabolomic analysis. We used UPLC-MS/MS analysis to compare the differences in metabolite changes between LLLT and COC before and after treatment. Results 76 differential metabolites were detected in the LLLT group, and 92 differential metabolites were detected in the COC group, which were up-regulated or down-regulated (p < 0.001). Prostaglandin D2 (PG D2) was down-regulated and biliverdin was up-regulated after LLLT treatment, 4a-Hydroxytetrahydrobiopterin, Prostaglandin D2, 5-Hydroxy-l-tryptophan, Cholic acid were down-regulated and cortisol was up-regulated after COC treatment, and the differences were statistically significant. Cortisol and testosterone glucuronide in LLLT group were significantly lower than those in COC group. The metabolic pathways affected were glycerophospholipid metabolism, linoleic acid metabolism and arachidonic acid metabolism in the LLLT group, and glycerophospholipid metabolism, folate biosynthesis, arachidonic-acid-metabolism, and tryptophan metabolism in the COC group. The differential metabolic pathway were linoleic acid metabolism, steroid hormone biosynthesis, and alpha-Linolenic acid metabolism after the comparison of LLLT with COC. Conclusion LLLT and COC might relieve dysmenorrhea by down-regulating PGD2, and LLLT might also relieve dysmenorrhea by up-regulating biliverdin. The level of cortisol and testosterone glucuronide after LLLT treatment was lower than that after COC treatment, which might lead to the difference in the clinical efficacy of the two treatments for dysmenorrhea.

Abstract
Background: This study aimed to compare the differences between reproductive endocrinologists (Repro-Endo) and obstetricians-gynecologists (Ob-Gyn; non-reproductive medicine specialty) in diagnosing, evaluating, and treating PCOS women with insulin resistance (IR).Methods: Repro-Endo and Ob-Gyn in China participated in this survey, and their responses were analyzed using χ2 tests, Fisher exact tests, and multivariable logistic regression analysis.Results: The study analyzed 2412 survey responses (92.3% OB-Gyn; 98.5% women). Physician's age, hospital grade, specialty, and the number of PCOS patients who visit the physicians, revealed that Repro-Endo participants were more likely to suggest an oral glucose tolerance test (OR, 1.727; 95% CI, 1.272-2.345) as their first choice than Ob-Gyn participants. The most common treatments for patients with PCOS were lifestyle modification (>95%) and metformin use (>80%). More Repro-Endo participants prescribed metformin at a dose of 1.5 g/day compared with OB-Gyn (46.5% vs. 23.5%), and more OB-Gyn participants reported being unclear about the appropriate dosage of metformin for patients with obesity and PCOS (12.5% vs. 1.6%).Conclusion: This survey identified knowledge gaps in metabolic screening for patients with IR and PCOS. Similarly, it highlights the need to improve IR management education for physicians caring for PCOS women.

Abstract
The pain relief formula “Ya Pa Som Kho-Khlan (YPSKK)” or “ยาผสมโคคลาน” in Thai is
officially recorded in the Natural List of Essential Medicines (NLEM) of
Thailand. The main component is Mallotus repandus (Willd.)
Müll. Arg.; however, Anamirta cocculus (L.) Wight & Arn and
Croton caudatus Gleiseler share the same common name:
“Kho-Khlan”. Confused usage of A. cocculus or
C. caudatus can have effects via toxicity
or unsuccessful treatment. This study aimed to combine a high-performance
thin-layer chromatography (HPTLC) technique and DNA barcoding coupled with
high-resolution melting (Bar-HRM) to differentiate M.
repandus from the other two species. The
M. repandus extract exhibited a distinct HPTLC
profile that could be used to differentiate it from the others. DNA barcodes of
the rbcL, matK, ITS and
psbA-trnH intergenic spacer regions of all
the plants were established to assist HPTLC analysis. The rbcL
region was selected for Bar-HRM analysis. PCR amplification was performed to
obtain 102 bp amplicons encompassing nine polymorphic nucleotides. The amplicons
were subjected to HRM analysis to obtain melting curve profiles. The melting
temperatures (Tm) of authentic A.
cocculus (A), C. caudatus
(C) and M. repandus (M) were separated at
82.03±0.09°C, 80.93±0.04°C and 80.05±0.07°C, respectively. The protocol was
applied to test crude drugs (CD1-6). The HPTLC profiles of CD2-6 showed distinct
bands of M. repandus, while CD1 showed unclear
band results. The Bar-HRM method was applied to assist the HPTLC and indicated
that CD1 was C. caudatus. While ambiguous
melting curves from the laboratory-made formulae were obtained, HPTLC analysis
helped reveal distinct patterns for the identification of the plant species. The
combination of HPTLC and Bar-HRM analysis could be a tool for confirming the
identities of plant species sharing the same name, especially for those whose
sources are multiple and difficult to identify by either chemical or DNA
techniques.

Abstract
The complexity of metabolites in traditional Chinese medicine (TCM) hinders the comprehensive profiling and accurate identification of metabolites. In this study, an approach that integrates enhanced column separation, mass spectrometry post-processing and result verification was proposed and applied in the identification of flavonoids in Dalbergia odorifera. Firstly, column chromatography fractionation, followed by liquid chromatography–tandem mass spectrometry was used for systematic separation and detection. Secondly, a three-level data post-processing method was applied to the identification of flavonoids. Finally, fragmentation rules were used to verify the flavonoid compounds. As a result, a total of 197 flavonoids were characterized in D. odorifera, among which seven compounds were unambiguously identified in level 1, 80 compounds were tentatively identified by MS-DIAL and Compound Discoverer in level 2a, 95 compounds were annotated by Compound discoverer and Peogenesis QI in level 2b, and 15 compounds were exclusively annotated by using SIRIUS software in level 3. This study provides an approach for the rapid and efficient identification of the majority of components in herbal medicines.

Abstract
The importance to clarify the drug metabolites is beyond doubt in view of their potential efficacy and safety. However, due to the complex matrix interference, relatively low content and the co-eluting effect, it is of a great challenge to comprehensively and systematically characterize the metabolites in vivo, especially for the traditional Chinese medicines (TCMs) due to the numerous types of components. In the present study, a comprehensive off-line two-dimensional separation system combining with data independent acquisition (DIA) mode and multi-dimensional data deconvolution method was established for chromatographic separation, data acquisition and data procession of indole alkaloids in rat plasma after intragastrically administrated with the extract of Uncaria rhynchophylla at the dose of 1 g/kg. The orthogonality of the off-line 2D separation system consisting of HILIC for first-dimensional separation and the PRLC for second-dimensional separation was valuated with the "asterisk" equations, and the results showed that off-line 2D separation system had passable orthogonality (A0 = 53.3%). Furthermore, the DIA mode was applied to capture MS/MS spectra in view of its advantage in acquiring MS data, and an effective multi-dimensional deconvolution method integrating the calculation of chemical formula, the extraction of diagnostic ion, the filter of ring double bond (RDB) and the judgement of neutral loss was established to parse the spectra for the complicated DIA data for comprehensive analysis of metabolites in rat plasma. Ultimately, a total of 127 indole alkaloids were tentatively characterized, and the main metabolic pathways were inferred as demethylation, dehydrogenation, hydroxylation and deglycosylation. The off-line two-dimensional separation system was applied for the comprehensive characterization of metabolites in vivo for the first time. This study suggested a new approach to enable the enrichment, separation and analysis of the low content components in vivo.
