ABSTRACT

The modernization and development of traditional Chinese medicine has led to higher standards for the quality of traditional Chinese medicine products. The extraction process is a crucial component of traditional Chinese medicine production, and it directly impacts the final quality of the product. However, the currently relied upon methods for quality assurance of the extraction process, such as simple wet chemical analysis, have several limitations, including time consumption and labor intensity, and do not offer precise control of the extraction process. As a result, there is significant value in incorporating near-infrared spectroscopy (NIRS) in the production process of traditional Chinese medicine to improve the quality control of the final products. In this study, we focused on the extraction process of Xiao'er Xiaoji Zhike oral liquid (XXZOL), using near-infrared spectra collected by both a Fourier transform near-infrared spectrometer and a portable near-infrared spectrometer. We used the concentration of synephrine, a quality control index component specified by the pharmacopoeia, to achieve rapid and accurate detection in the extraction process. Moreover, we developed a model transfer method to facilitate the transfer of models between the two types of near-infrared spectrometers (analytical grade and portable), thus resolving the low resolution, poor performance, and insufficient prediction accuracy issues of portable instruments. Our findings enable the rapid screening and quality analysis of XXZOL onsite, which is significant for quality monitoring during the traditional Chinese medicine production process.

ABSTRACT

OBJECTIVE To explore the curative effect and mechanism of Yiqi Huoxue decoction in the treatment of coronary heart disease with Qi deficiency and blood stasis syndrome. METHODS The patients with coronary heart dis?ease of Qi deficiency and blood stasis syndrome were treated with Yiqi Huoxue decoction for 3 months, and the changes of cardiac function were observed. 61 serum samples (including 29 cases of disease group and 32 cases of Yiqi Huoxue expression group) were analyzed by non labeled proteomics. The disease group was used as the control group, and the protein with expression level difference of more than 1.2 folds (P<0.05) was screened. The molecular function, biologi?cal pathway and protein interaction of the different proteins were analyzed by bioinformatics, so as to identify the molecu?lar and biological pathway of Yiqi Huoxue decoction in the treatment of coronary heart disease with Qi deficiency and blood stasis syndrome. RESULTS Clinical treatment found that Yiqi Huoxue decoction can improve TCM syndrome score and left ventricular ejection fraction, regulate blood glucose and blood lipid levels, prolong thrombin time, and improve heart function. The results of proteomic quantitative analysis showed that there were 69 proteins with different expression levels in the disease group. Bioinformatics analysis results showed that Yiqi Huoxue decoction may regulate ApoA1, alpha-2 and other proteins to act on HDL assembly, platelet degradation, PI3K Akt signaling pathway, and then play a therapeutic role in coronary heart disease with Qi deficiency and blood stasis syndrome. CONCLUSION Yiqi Huoxue decoction can effectively improved the heart function decline caused by Qi deficiency and blood stasis syn?drome of coronary heart disease. It mainly act on energy metabolism and platelet activation pathway by activating HDL assembly and platelet degradation signal pathway proteins. This study can provide reference for the follow-up treatment mechanism of Qi deficiency and blood stasis syndrome of coronary heart disease.

ABSTRACT

Chinese medicine Buyang Huanwu decoction (BYHW) is widely used in treating cerebral infarction combined with Qi-deficiency and blood-stasis syndrome, but the pharmacological basis is still not clear. This study aims to uncover the biological basis of BYHW therapy for cerebral infarction combined with Qi-deficiency and blood-stasis syndrome using label-free proteomic technology. Using Qi deficiency and blood stasis rat cerebral infarction model as the research object, the protein expression of rat brain tissue was compared among the sham operation group, the model group and the drug group. Quantitative analysis of the 3 groups of tissue samples detected 3 959, 3 996 and 4 055 proteins in the sham operation group, the model group and the drug group, respectively. Take model group as the control group, 391 proteins were identified to be upregulated or downregulated for more than 2 folds. Biological analysis and functional enrichment of the differentially expressed proteins revealed that BYHW may treat cerebral infarction combined with Qi-deficiency and blood-stasis syndrome through energy metabolism, nervous system and several signal pathways. This study preliminarily revealed the pharmacological mechanism of BYHW at the protein level, and provided a molecular basis for clinical treatment and traditional Chinese medicine research on cerebral infarction combined with Qi-deficiency and blood-stasis syndrome.

ABSTRACT

Objective@#To explore the mechanisms of oxidative stress-induced damage to TM4 Sertoli cells in the mouse using metabolomics techniques based on gas chromatography-mass spectrometry (GC-MS).@*METHODS@#We established the model of oxidative stress-induced damage to mouse TM4 Sertoli cells by treatment with H₂O₂. Then, we detected the survival rate and apoptosis rate of the TM4 cells by MTT and flow cytometry respectively, measured the concentration of ROS in the TM4 cells with the DCFH-DA fluorescent probe, and determined the levels of endogenous metabolites in the TM4 cells by GC-MS after H₂O₂ intervention.@*RESULTS@#After 2 hours of treatment with H₂O₂ at 600 μmol/L, the survival rate of the TM4 cells was reduced to about 50%, and the total apoptosis rates in the low- (100 μmol/L), medium- (300 μmol/L), and high-dose (600 μmol/L) groups were (19.45 ± 0.53), (20.12 ± 0.58), and (37.13 ± 0.35)%, respectively, increased in a dose-dependent manner as compared with (10.28 ± 0.35)% in the blank control (P 1, P <0.05).@*CONCLUSIONS@#Oxidative stress-induced damage and apoptosis of TM4 Sertoli cells are closely associated with the metabolism of amino acid, glucose, and energy in the cells.

ABSTRACT

The present study was designed to observe the protection of Grateloupia filicina polysaccharide (GFP) against hepatotoxicity induced by Dioscorea bulbifera L in mice and its underlying mechanism. GFP was intragastrically (ig) given to mice at various doses. After 6 days, the mice were treated with ethyl acetate extract of Dioscorea bulbifera L (EF, ig). Serum levels of alanine/aspartate aminotransferase (ALT/AST), alkaline phosphatase (ALP), total bilirubin (TB) were measured, and liver histological evaluation was conducted. Furthermore, reductions of liver glutathione (GSH) amount and glutamate cysteine ligase (GCL) activity were tested. The expressions of GCL-c, GCL-m, and HO-1 (heme oxygenase-1) in liver were observed by Western-blot. The results showed that GFP (600 mg x kg(-1)) decreased EF-induced the increase of serum ALT, AST and TB, and GFP (400, 600 mg x kg(-1)) inhibited EF-induced the increase of serum ALP. Liver histological evaluation showed that the liver injury induced by EF was relieved after treated with GFP. GFP further increased liver GSH amount and reversed EF-induced the decrease of GCL activity. The Western-blot result showed that GFP augmented EF-induced the increase of HO-1, and reversed EF-induced the decrease of GCL-c. In conclusion, GFP can act against the oxidative stress liver injury induced by Dioscorea bulbifera L in mice.

ABSTRACT

The aim of the present study is to investigate the effect and mechanism of Coeloglossum viride var. bracteatum extract (CE) on scopolamine-induced learning and memory deficits. Learning and memory deficits of mice were evaluated by step-down passive avoidance test. Long-term potentiation of rats was detected in the dentate gyrus of hippocampus. Brain acetylcholinesterase (AChE) and choline acetyltransferase (ChAT) activities were also determined. The results showed that scopolamine impaired learning and memory performance and LTP induction in hippocampus. Oral administration of CE (5, 10, and 20 mg x kg(-1)) significantly alleviated scopolamine-induced memory deficits measured by step-down test (P < 0.05). CE (5 mg x kg(-1), ip) significantly reversed the inhibitory effect of scopolamine on LTP in rats. In addition, CE was found to increase the activity of ChAT in rat brain. These results suggested that CE could alleviate scopolamine-induced learning and memory deficits, which might be due to the LTP-improvement and ChAT activity enhancement.

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect and possible mechanism of xiongshao capsule (XSC) on lipid metabolism and platelet aggregation in experimental atherosclerotic (AS) rabbits.</p><p><b>METHODS</b>Fractional AS rabbits model was established by denuding endothelium of abdominal aorta with 4F x Fogarty catheter, followed by high cholesterol feeding. Seventy model rabbits were equally randomized into 7 groups, namely, the 3 model groups (Group A, B and C) of different observation time (3 days, 2 weeks and 6 weeks respectively after operation); the single endothelium injury group (Group D, adopted denuding but fed with common diet); the 3 treatment groups treated respectively with probucol (Group E), low-dose and high-dose XSC (Group F and G) for 6 weeks. Besides, a control group (Group N) consisting of 10 rabbits underwent sham operation with normal feeding was set up. Animals were killed at different corresponding time points, heart blood was collected before killing for measurements of blood lipid indexes, including total cholesterol (TC), total triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). The 5 min maximum platelet aggregation rate (mPAGR) was measured with heart blood on the 3rd day after operation and at the terminal of experiment.</p><p><b>RESULTS</b>(1) Indexes of blood lipids were unchanged in Group D and N (P > 0.05); TC and LDL-C in model rabbits began to rise significantly after being fed with high fat forage for 3 days; lipid indexes in Group A, B and C were significantly different to those in Group N, respectively (P < 0.05, P < 0.01); at the end of experiment TC and LDL-C were lower in Group G and E when compared with Group C; the ratio of LDL-C/HDT-C decreased in Group G, E and F, especially in Group G (P < 0.01); a bettering trend of HDL-C presented in Group G, but not in Group E; and reduction of atherosclerosis index (AI, calculated by TC/HDL-C) was found in Group G (P < 0.01), significant difference was shown as compared with that in Group C and E (P < 0.05). (2) The 3rd day mPAGR raised in Group A, B, C and D, showing significant difference as compared with that in Group N (P < 0.01), whereas the index in Group E, F and especially in G was lower significantly than that in Group C (P < 0.05). mPAGR in the 3 treatment groups at the terminal of experiment was lower than that in Group C (P < 0.05, P < 0.01), and the most effective lowering was shown in Group G.</p><p><b>CONCLUSION</b>XSC could reduce the levels of TC, LDL-C and AI in AS model rabbits, also inhibit platelet aggregation at early stage and 6 weeks after endothelium injury, which might be one of the possible acting mechanisms of XSC in preventing AS.</p>
