Efficacy of ginseng-based Renshenguben oral solution for cancer-related fatigue among patients with advanced-stage hepatocellular carcinoma:A prospective multicenter cohort study

Background:Cancer-related fatigue(CRF)is a common and debilitating symptom experienced by patients with advanced-stage cancer,especially those undergoing antitumor therapy.This study aimed to evaluate the efficacy and safety of Renshenguben(RSGB)oral solution,a ginseng-based traditional Chinese medicine,in alleviating CRF in patients with advanced hepatocellular carcinoma(HCC)receiving antitumor treatment.Methods:In this prospective,open-label,controlled,multicenter study,patients with advanced HCC at BCLC stage C and a brief fatigue inventory(BFI)score of≥4 were enrolled.Participants were assigned to the RSGB group(RSGB,10 mL twice daily)or the control group(with supportive care).Primary and secondary endpoints were the change in multidimensional fatigue inventory(MFI)score,and BFI and functional assessment of cancer therapy-hepatobiliary(FACT-Hep)scores at weeks 4 and 8 after enrollment.Adverse events(AEs)and toxicities were assessed.Results:A total of 409 participants were enrolled,with 206 assigned to the RSGB group.At week 4,there was a trend towards improvement,but the differences were not statistically significant.At week 8,the RSGB group exhibited a significantly lower MFI score(P<0.05)compared to the control group,indicating improved fatigue levels.Additionally,the RSGB group showed significantly greater decrease in BFI and FACT-Hep scores at week 8(P<0.05).Subgroup analyses among patients receiving various antitumor treatments showed similar results.Multivariate linear regression analyses revealed that the RSGB group experienced a significantly substantial decrease in MFI,BFI,and FACT-Hep scores at week 8.No serious drug-related AEs or toxicities were observed.Conclusions:RSGB oral solution effectively reduced CRF in patients with advanced HCC undergoing antitumor therapy over an eight-week period,with no discernible toxicities.These findings support the potential of RSGB oral solution as an adjunctive treatment for managing CRF in this patient population.

Study on Detection of Organochlorine Pesticide Residue in Ginseng

To investigate the residue situation of pesticides in ginseng, total 17 samples of ginseng-growing soil, ginseng roots and ginseng seeds were collected from 5 regions of Fusong County, and the contents of organochlorine pesticide residues in the samples were detected by using ultrasonic-assisted extraction and gas chromatography with acetone-ligroin as the solvent, thereby providing suitable recommendations and scientific basis for the selection of ginseng-growing soil.

Activation of Plasma Membrane NADPH Oxidase and Generation of H_2O_2 Mediate the Induction of PAL Activity and Saponin Synthesis byEndogenous Elicitor in Suspension-Cultured Cells of Panax ginseng

Endogenous elicitor, termed cellulase-degraded cell wall (CDW), was prepared from the cell wall of suspension-cultured ginseng (Panax ginseng C.A. Meyer) cells via cellulase degradation. CDW activated the NADPH oxidase activity of isolated plasma membranes and stimulated in vivo H2O2 generation in ginseng cell suspensions. CDW also increased the activity of phenylalanine ammonia lyase (PAL), expression of a P. ginseng squalene epoxidase (sqe) gene and saponin synthesis. NADPH oxidase inhibitors inhibited both in vitro NADPH oxidase activity and in vivo H2O2 generation. Induction of PAL activity, saponin synthesis and sqe gene expression were all inhibited by such inhibitor treatments and reduced by incubation with catalase and HA scavengers. These data indicate that activation of NADPH oxidase and generation of H2O2 are essential signalling events mediating defence responses induced by the endogenous elicitor(s) present in CDW.

Study of the efficacy of Korean Red Ginseng in the treatment of erectile dysfunction

Aim： To examine the treatment efficacy of Korean Red Ginseng （KRG） in impotent men with erectile dysfunction （ED）. Methods： A total of 60 patients presenting mild or mild to moderate ED were enrolled in a double-blind, placebo-controlled study in which the efficacies of KRG and a placebo were compared. The patients received either 1 000 mg （3 times daily） of KRG or a placebo. Results： The five-item version of the International Index of Erectile Function （IIEF-5） score after the treatment was significantly higher in the KRG group compared with that before the treatment （from 16.4±2.9 to 21.0±6.3, P 〈 0.0001）. In contrast, there was no difference before and after the treatment in the placebo group （from 17.0±3.1 to 17.7±5.6, P 〉 0.05）. In the KRG group, 20 patients （66.6%）, reported improved erection, significant in the global efficacy question （P 〈 0.01）; in the placebo group there was no significance. Scores on questions 2 （rigidity）, 3 （penetration）, 4 and 5 （maintenance）, were significantly higher for KRG than those for the placebo when those questions were answered after 12 weeks of each treatment （P 〈 0.01）. When the score in the KRG group was compared to the placebo group after the treatment, there was a significant improvement in total score （IIEF-5 score） in questions 3 and 5 for the KRG-treated group （P 〈 0.001 and P 〈 0.0001, respectively）. The levels of serum testosterone, prolactine and cholesterol after the treatment were not statistically significant different between the KRG and the placebo group （P 〉 0.05）. Conclusion： Our data show that KRG can be an effective alternative to the invasive approaches for treating male ED.

Analysis of Low-polar Ginsenosides in Steamed Panax Ginseng at High-temperature by HPLC-ESI-MS/MS

A high performance liquid chromatography coupled with electrospray ionization-tandem mass spectrome try（HPLC-ESI-MS/MS） method was developed for the analysis and identification of ginsenosides in the extracts of raw Panax ginseng（RPG） and steamed Panax ginseng at high temperatures（SPGHT）. A total of 25 ginsenosides were extracted include of which 10 low-polar ginsenosides, such as ginsenosides F4, Rk3, Rh4, 20S-Rg3, 20R-Rg3 and so on, were identified according to their HPLC retention time and MS/MS data. The results indicated that the low polar ginsenosides were seldom found in RPG. For the exploration of the transformation pattern of the ginsenosides in steam processing, the standards of ginsenosides Re, Rg1, Rb1, Rc, Rb2, Rb3 and Rd were selected and hydrolyzed at a temperature of 120 oC. The results show that these polar ginsenosides can be converted to low-polar ginsenosides such as Rg2, Rg6, F4, Rk3 and Rg5 by hydrolyzing the sugar chains.

Effects of tissue-cultured mountain ginseng （Panax ginseng CA Meyer） extract on male patients with erectile dysfunction

Korean ginseng and mountain ginseng （Panax ginseng CA Meyer） are important traditional herbal plants whose ginsenosides are generally accepted as serving to improve sexual functions, such as penile erection. We investigated the effects of tissue-cultured mountain ginseng extract （TMGE） on male patients with erectile dysfunction （ED）. A double-blind, placebo-controlled study was conducted with 143 patients experiencing ED. Over the course of 8 weeks, one group took 1 000 mg of TMGE twice a day, and the other group took 1 000 mg of placebo twice a day. The effects of the TMGE and the placebo were analyzed using the Korean version of the International Index of Erectile Function （IIEF） questionnaire. A total of 86 patients completed 8 weeks of treatment. The scores on the five domains of the IIEF after medication were significantly higher than the baseline scores in the group treated with TMGE （P 〈 0.05）, whereas no significant improvement was observed in the placebo group （P 〉 0.05）. Erectile function and overall satisfaction scores after medication were significantly higher in the TMGE group than in the placebo group （P 〈 0.05）. Erectile function of patients in the TMGE-treated group significantly improved, suggesting that TMGE could be utilized for improving erectile function in male patients.

Structure Analysis of Pectin SB_(1-1) from the Root of Panax ginseng

A water-soluble pectin SB_~1-1 was isolated and purified from the root of Panax ginseng C. A. Mey. The HPLC analysis indicates that SB_~1-1 is homogenous. Its molecular weight was estimated via gel filtration to be 10000. The GC analysis indicated that it contains the monosaccharides of GalA, Gal, Ara and Rha. Their molar ratio is 2.10∶1.00∶0.12∶0.13. Partial hydrolysis with acid, pectinase treatment, periodate oxidation, Smith degradation, methylation analyses, GC/MS analyses and NMR analyses were used for the structure analyses of SB_~1-1 . The results reveal that SB_~1-1 has a lower branched structure. The main chain is composed of GalA and Gal; the inner part is α-1,4-linked-GalA; the border is 1,4-linked-Gal. Some of the 1,4-linked-GalA and 1,4-linked-Gal residues are substituted at O6. On an average, there is one branch for every ten hexose residues. The side chain is composed of 1,6-linked-Gal and 1,3,6-linked-Gal. The nonreduced end is composed of Rha, Ara and Gal. The main glycosidic link of SB_~1-1 has an α configuration.

Effects of Korean ginseng berry extract （GB0710） on penile erection： evidence from in vitro and in vivo studies

Several reports have promoted the root-derived Korean red ginseng （KRG; Panax ginseng） as alternative treatment for erectile dysfunction （ED）, and ginsenosides are known to be the principal active ingredients of ginseng. Recent studies showed that ginseng berries produce more ginsenosides than KRG; thus, we investigated the ability of the Korean ginseng berry extract GB0710 to relax the penile corpus cavernosum smooth muscle （CCSM） in this study. As a comparative control, the results were compared to those obtained using KRG. In addition, possible mechanisms of action for GB0710 were investigated. While KRG and GB0710 both displayed dose-dependent relaxation effects on precontracted rabbit CCSM in vitro, GB0710 was shown to be more potent than KRG. The GBO710-induced relaxation could be partially reduced by removing the endothelium. In addition, pre-treatment with several nitric oxide （NO） inhibitors significantly inhibited the relaxation of muscle strips. Furthermore, administration of GB0710 increased intracavernosal pressure （ICP） in a rat in vivo model in both a dose- and duration-dependent manner. Intracellular NO production in human microvascular endothelial cells could be induced by GB0710 and inhibited by NG-monomethyI-L-arginine. In conclusion, GB0710 had a greater relaxation effect on rabbit CCSM than did KRG extract, and increased ICP in a rat model in both a dose- and a duration-dependent manner. This relaxine effect might be mediated bv NO production.

Comparative Study on Extraction Technology and Activity of Total Flavonoids from Ginseng Flowers

[Objectives] To compare the effects of different extraction technologies on the extraction of total flavonoids from ginseng flowers.[Methods]Taking the ginseng flower as raw material,and the total flavonoids of ginseng flower were extracted by water extraction,ethanol extraction,freeze-thaw,ultrasonic extraction,and microwave extraction.The scavenging ability of total flavonoids and Vc to DPPH free radicals and hydroxyl radicals were compared between ultrasonic extraction and water extraction.[Results]The yield of ultrasonic and microwave technology was relatively high.In this study,the ultrasonic extraction was taken as the main method,ethanol aqueous solution was used as the solvent,and single factor experiment was carried out with ultrasonic power,ethanol volume,solid to liquid ratio and time as the variables.The best extraction process of flavonoids was ultrasonic power of 120 Hz,ethanol concentration of 60%,solid to liquid ratio of 1∶ 30,and ultrasonic time of 80 s.Under these conditions,the yield of flavonoid extraction was 6.72 mg/g.[Conclusions] The flavonoids obtained by ultrasonic extraction and microwave extraction have the highest antioxidant capacity,65.4% and 53.5%,respectively,indicating that the ultrasonic extraction and microwave extraction technologies are more suitable for the extraction of flavonoids from the ginseng flower.

Microsatellite Analysis of <i>Panax ginseng</i>Natural Populations in Russia

Panax ginseng C.A. Meyer is an endangered species in Russia. To restore this species, effective protective measures, including the reintroduction into favorable habitats, must be worked out considering the specificity of genetic structure of ginseng populations. One hundred and thirty-nine P. ginseng plants were collected from the forests of nine administrative areas of Primorsky Territory of Russia and transferred to a collection nursery for further investigation. Microsatellite markers were used to study the genetic diversity and the genetic structure of ginseng populations. For populations studied with SSR, the number of observed alleles was ranging from 15 to 25, allelic richness from 1.83 to 3.04, polymorphic loci from 62.5% to 87.7%, observed heterozygosity from 0.410 to 0.512 (an average of 0.453) and expected heterozygosity from 0.304 to 0.479, with an average of 0.393. The values of the inbreeding coefficient within populations (Fis) ranged from -0.447 to 0.056, and their average value was -0.296. Genetic differentiation among populations was significant (Fst = 0.115) but an isolation-by-distance pattern was not detected. UPGMA and MS-tree confirmed the presence of genetic structure within P. ginseng and visualized genetic relationships of populations with similar pattern. STRUCTURE analysis revealed the genetic admixture between different ginseng populations. It was established with SSR markers that P. ginseng still preserves substantial genetic resources although all populations are largely exhausted. Because ginseng populations are significantly differentiated all of them should be restored. Considering the admixture of ginseng populations it would be advisable to apply the individual assignment test to verify the content of indigenous populations and to identify the "true" population plants to serve as stock material for reintroduction.

Clinical potentials of ginseng polysaccharide for treating gestational diabetes mellitus

Gestational diabetes mellitus(GDM)is the most common glucose metabolism complication or cause of potential impaired glucose tolerance that can occur either before or during pregnancy and lactation.The prevalence of GDM and its related complications in young women is increasing,and this condition may cause serious outcomes and health hazards to the foetus.However,traditional oral hypoglycaemic drugs have potential safety hazards;therefore,it is urgent to develop new,safe,effective,and easily administered agents and remedies.Ginseng polysaccharide(GPS),which is isolated from Panax(P.)ginseng C.A.Meyer,exhibits notably promising biological activities and effects;specifically,it has been shown to lower blood glucose with mild,safe,and nontoxic characteristics,and it can also improve human bodily functions.Hence,we hypothesise that GPS might be used as an additional therapy and candidate agent for treating GDM.This review innovatively summarizes the available reports and evidence from basic studies to analyze the potential for and feasibility of using GPS as a new therapeutic agent for treating GDM.Additionally,for the first time,this review provides a rationale for the use of GPS.Our summarized results show that GPS may be developed as a novel antidiabetic drug and a remedy for use in preventing and treating GDM,with great application prospects.

秦川牛宰后成熟过程中线粒体翻译延长因子Tu与能量代谢的关联性分析

目的:线粒体翻译延长因子Tu(mitochondrial Tu translation elongation factor,TUFM)已被证明参与秦川牛宰后成熟过程中的细胞自噬活动,实验探究该过程中TUFM表达与能量代谢变化的关系。方法:以秦川牛背最长肌为研究对象,测定4℃不同成熟时间(0、2、12、24、48、96、144、192 h)TUFM表达量及含量、葡萄糖(glucose,GLU)、乳酸(lactic acid,LA)、腺苷三磷酸(adenosine triphosphate,ATP)、二磷酸腺苷(adenosine diphosphate,ADP)、单磷酸腺苷(adenosine monophosphate,AMP)6种物质含量以及乳酸脱氢酶(lactate dehydrogenase,LDH)、琥珀酸脱氢酶(succinate dehydrogenase,SDH)、磷酸丙糖异构酶(triose phosphate isomerase,TPI)、苹果酸脱氢酶(malate dehydrogenase,MDH)、细胞色素c氧化酶(cytochrome c oxidase,COX)5种酶活性的变化情况。结果:在秦川牛宰后成熟期间,GLU、ATP、ADP、AMP含量和LDH、SDH、TPI活性均呈下降趋势,TUFM表达量、MDH活性及LA和TUFM含量均呈先上升后下降趋势,COX活性呈先下降后上升再下降趋势。能量代谢各指标和TUFM蛋白主要在宰后初期发挥作用,对宰后初期及宰后中后期分别进行Pearson相关性分析,结果表明,在宰后初期牛背最长肌中TUFM表达量与MDH、LA呈极显著正相关(P<0.01),与ATP、ADP、AMP、LDH、SDH、TPI、COX、GLU呈极显著负相关(P<0.01)。在宰后中后期,TUFM表达与所有指标(GLU、LA、ATP、ADP、AMP、LDH、MDH、SDH、TPI、COX)均呈极显著正相关(P<0.01)。结论:在宰后初期TUFM表达量逐渐增加,可为肌肉细胞提供能量从而用于能量代谢途径,该过程可能是TUFM正向参与细胞自噬所致。在宰后中后期能量短缺时,TUFM可能抑制细胞自噬,优先将能量用于除细胞自噬外的其他重要途径(如能量代谢途径)以维持细胞稳态。综上,在宰后成熟过程中TUFM具有双重作用,可调节细胞自噬为能量代途径提供能量,有助于维持宰后能量代谢持续的时间。
