Abstract
Modern studies have shown that neuroendocrine disorders caused by the dysfunction of the hypothalamic-pituitary-gonadal (HPG) axis are one of the important pathogenetic mechanisms of kidney-yang-deficiency-syndrome (KYDS). The preventive effect of Gushudan on KYDS has been reported, but its regulatory mechanisms on the HPG axis have not been elucidated. In this study, we developed an integrated untargeted and targeted metabolomics analysis strategy to investigate the regulatory mechanism of Gushudan on the HPG axis in rats with KYDS. In untargeted metabolomics, we screened 14 potential biomarkers such as glycine, lysine, and glycerol that were significantly associated with the HPG axis. To explore the effect of changes in the levels of potential biomarkers on KYDS, all of them were quantified in targeted metabolomics. With the quantitative results, correlations between potential biomarkers and testosterone, a functional indicator of the HPG axis, were explored. The results showed that oxidative stress, inflammatory response, and energy depletion, induced by metabolic disorders in rats, were responsible for the decrease in testosterone levels. Gushudan improves metabolic disorders and restores testosterone levels, thus restoring HPG axis dysfunction. This finding elucidates the special metabolic characteristics of KYDS and the therapeutic mechanism of Gushudan from a new perspective.

Suppression of Inflammatory and Fibrotic Signals by Cinnamon (Cinnamomum cassia) and Cinnamaldehyde in Cyclophosphamide-Induced Overactive Bladder in Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:5205759. [PMID: 34976095 PMCID: PMC8716214 DOI: 10.1155/2021/5205759] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 11/19/2021] [Accepted: 12/03/2021] [Indexed: 11/18/2022]
Abstract
Cinnamon (Cinnamomum cassia) is a well-known traditional Chinese medicine used to treat nocturia by tonifying and warming the kidney. Our recent clinical study found that overactive bladder (OAB) patients treated with cinnamon powder (CNP) patches exhibited significantly ameliorated OAB symptoms without significant side effects, but the mechanism of action is unclear. To explore the beneficial effects and action mechanisms of CNP and its major active component cinnamaldehyde (CNA) in an OAB-related murine model, cyclophosphamide- (CYP-) induced OAB injury was performed on male ICR mice in the presence or absence of CNP and CNA, as well as solifenacin, a clinical drug for OAB as a reference. Twenty-four-hour micturition patterns (frequency of urination and volume of urine per time), as well as histopathological examination, immunohistochemistry (IHC), and Western blotting of the bladder, were analyzed for mechanism elucidation. Administration of CYP (300 mg/kg, i.p.) induced typical OAB pathophysiological changes, including increased frequency of urination and reduced volume of urine. CYP-induced mice displayed strong edema of the bladder and hemorrhagic cystitis, accompanied by loss of normal corrugated folds and decreased muscarinic receptors (M2/M3) in the urothelium, and disordered/broken structures of the lamina propria and detrusor. These changes were correlated with increased leukocyte (CD11b) infiltration colocalized with inflammatory (pp65 NFκB, macrophage migration inhibitory factor (MIF)/Toll-like receptor 4 (TLR4)) and fibrotic (stem cell factor (SCF)/c-Kit, α-smooth muscle actin (α-SMA)/β-catenin) signals. Treatment with CNP (600 mg/kg, p.o.) and CNA (10–50 mg/kg, p.o.), but not solifenacin (50 mg/kg), 30 min after CYP induction significantly ameliorated CYP-induced dysfunction in micturition patterns and pathophysiological changes. CNP and CNA further suppressed MIF/TLR4-associated inflammatory and SCF/c-Kit-related fibrotic signaling pathways. Our findings indicate that suppression of inflammatory and fibrotic signals contributes to the crucial mechanism in the improvement of CYP-induced OAB by CNP and CNA.

Efficacy of cinnamon patch treatment for alleviating symptoms of overactive bladder: A double-blind, randomized, placebo-controlled trial. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 80:153380. [PMID: 33091856 DOI: 10.1016/j.phymed.2020.153380] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 09/20/2020] [Accepted: 10/11/2020] [Indexed: 05/24/2023]
Abstract
BACKGROUND Current treatments for overactive bladder (OAB) have limited efficacy, low persistence and a high rate of adverse events commonly leading to treatment cessation in clinical practice. Clinicians in Asia commonly use traditional Chinese medicine as an alternative for OAB treatment despite it having uncertain efficacy and safety. To evaluate the efficacy and safety of cinnamon patch (CP) treatment for alleviating symptoms of OAB, a double-blind randomized, placebo-controlled trial was conducted in the present study. MATERIALS AND METHODS In this 6-week randomized clinical trial conducted in an outpatient setting, 66 subjects diagnosed as having OAB were enrolled and treated with a placebo (n=33) or CP (n=33). The OAB symptom score (OABSS) was selected as the primary end point, and a patient perception of bladder condition (PPBC), an urgency severity scale (USS), and post-voiding residual urine (PVR) volume were selected as secondary end points. Statistical analyses were performed with IBM SPSS Statistics 20. Groups were compared using an independent sample t-test, Fisher exact test, and Chi-squared test. RESULTS In total, 66 participants (40 women and 26 men), 60.35 ± 12.77 years of age, were included in the intention-to-treat analyses. Baseline characteristics were comparable between the CP (n ==33) and placebo (n ==33) groups. Treatment with a CP showed statistically significant differences in reductions in OABSS scores (9.70 ± 2.20 to 6.33 ± 2.42), PPBC scores (3.36 ± 0.60 to 2.15 ± 0.83), and USS scores (2.67 ± 0.54 to 1.64 ± 0.60). CONCLUSIONS Compared to a placebo, treatment with CP might be considered an effective and safe complementary therapy for OAB. Further studies employing a positive control, different dosage forms, larger sample sizes, and longer treatment periods are warranted.

JOURNAL OF ETHNOPHARMACOLOGY 2019; 243:112108. [PMID: 31349028 DOI: 10.1016/j.jep.2019.112108] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/17/2019] [Revised: 07/06/2019] [Accepted: 07/23/2019] [Indexed: 05/19/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE One important therapeutic characteristic of traditional Chinese medicine (TCM) for its properly-guided clinical prescription is considering the cold and hot medicinal properties of traditional Chinese herbs. According to the TCM theory, the hot and cold medicinal properties are defined by the general responses of a human body to a given herbal medicine. This definition is subjective and ambiguous which attenuates the modernization of TCM. Biological spontaneous photon emission (SE) is a normal phenomenon reflecting the transition of the quantum state of molecules inside an organism. The alteration of its level can indicate the changes of many aspects of the organism including metabolism. Thus, we can exploit this feature to develop a novel and scientific approach to quantitively and objectively characterize the hot and cold medicinal properties of traditional Chinese herbs. OBJECTIVE To determine whether SE can be used to characterize the hot and cold medicinal properties of traditional Chinese herbs, this study took advantage of the ultra-weak luminescence detection technology to examine the effects of traditional Chinese herbs with hot or cold medicinal property to the level of SE in mice. MATERIALS AND METHODS Mice were intragastrically administered with twenty traditional Chinese herbs harboring cold or hot property for ten consecutive days respectively. During the course of treatment, SE intensity of the abdomen and the back of each individual mouse were measured and recorded. At the end of the treatment, the total antioxidant capacity, superoxide dismutase activity, Na+-K+-ATPase activity and Ca2+-Mg2+-ATPase activity in the liver of all mice were examined. RESULTS Ratio between the SE intensity of the abdomen and back of mice (defined as SE ratio) was able to distinguish the cold and hot medicinal properties of traditional Chinese herbs. Mice treated with hot herbs and cold herbs have higher and lower SE ratios respectively compared with control mice. Furthermore, levels of selected biochemical indexes in the liver were correlated with most of the SE ratio changes induced by herbal treatment. CONCLUSIONS We have developed a novel and promising approach to quantitatively investigate herbal properties and we propose that SE ratio defined in this study can serve as a sensitive parameter to characterize the cold and hot medicinal properties of traditional Chinese herbs.

Combined administration on You-Gui Yin and low-dose Raloxifene partially attenuates the bone loss in ovariectomized mice through the proliferation and osteogenic differentiation of bone marrow stromal cells. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 53:286-293. [PMID: 30668409 DOI: 10.1016/j.phymed.2018.09.014] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/11/2017] [Revised: 07/16/2018] [Accepted: 09/03/2018] [Indexed: 06/09/2023]
Abstract
BACKGROUND Osteoporosis is a systemic skeletal disease of fragility fractures due to the loss of mass and deterioration of the microarchitecture of bone. PURPOSE The aim of the study was to assess the osteogenic effects and the underlying mechanisms of the combined administration of You-Gui Yin (YGY) and Raloxifene hydrochloride (RLX) in ovariectomized (OVX) mice. METHODS First, a classic animal model was used to mimic postmenopausal osteoporosis through the removal of the ovary of mice. Second, the OVX mice were administered YGY, RLX, and YGY + RLX for 12 weeks. Next, the bone microtomographic histomorphometry and bone mineral density (BMD) were assessed by micro-CT, and the biochemical markers of procollagen type I N-terminal propeptide (P1NP) and beta-isomerized C-telopeptide (β-CTX) in serum were assessed. Finally, primary bone marrow stromal cells (BMSCs) were isolated from the tibia and cultured to evaluate cell proliferation and osteogenic differentiation. RESULTS The results showed that BMD on the YGY + RLX group was higher than that on the RLX group (p < 0.05) and did not have a significant difference when compared with the sham group. Notably, the YGY + RLX group had a dramatically increased trabecular number (Tb.N) compared with that of the YGY group (p < 0.05). Moreover, the BV/TV (bone volume/total volume) and Tb.N in the YGY + RLX group were higher than that in the RLX group (p < 0.05), and the Tb.Sp (trabecular separation) was lower than that in the RLX group (p < 0.05). Moreover, the serum level of P1NP from the YGY + RLX group dramatically increased when compared with that from the YGY and RLX groups (YGY group: p < 0.05; RLX groups: p < 0.01). Notably, there was no significant difference between the YGY and YGY + RLX groups. In addition, cell proliferation from the co-administration of YGY and RLX was clearly higher than a single use of YGY and RLX (p < 0.01, respectively). The ALP/BCA (alkaline phosphatase/bicinchoninic acid) in the YGY + RLX group was higher than that in the RLX group (p < 0.01). CONCLUSION Overall, co-administered YGY and RLX could partially attenuate bone loss and were more effective than individually using either one; this outcome might be associated with the proliferation and osteogenic differentiation of BMSCs.

Abstract
OBJECTIVE To explore an approach to rapidly and accurately identify the compounds as biomarkers of Chinese medicine (CM) syndromes. METHOD The Fourier transform infrared (FT-IR) spectrometry was applied to investigate the characteristic components of a mice model of Kidney (Shen)-yang deficiency syndrome (KDS), and the remedial effect of a typical CM formula Shenqi Pill (). Thirty-six females and 18 males of Balb/c mice were randomly divided into KDS, Shenqi or control group. The females and males of the same group freely were mated for 96 h, and the males were taken out and only the female mice were raised. Females of the KDS group were threatened by a ferocious cat every other day for 14 d. After delivery, the KDS, or gestational threatened, offspring were raised at standard condition for 11 weeks. Then 10 male offspring were randomly selected, anaesthetized and their representative organs, i.e. testes, kidneys, lungs and feet were collected, for the FT-IR scan. Mice of the Shenqi group were intragastric administered Shenqi Pill; while mice in the KDS and control groups were given the same volume of saline. RESULTS The attenuated birth outcomes of the KDS group were displayed. The remarkable FT-IR differences of all organs between KDS mice and healthy control were mainly at 1,735-1,745 cm(-1) (indicating the increased levels of lipids) and at 1,640-1,647 cm(-1) and 1,539-1,544 cm(-1) (displaying the decreased proteins). No statistic FT-IR difference between Shenqi and control mice was observed. CONCLUSION In accordance with major traits of KDS, prenatal stress extensively impaired the building up of proteins and resulting in the excessive lipid storage, and FT-IR could effectively identify the biomarkers of KDS.

Abstract
Microarrays are widely used to study changes in gene expression in diseases. In this paper, we use this technology to discover gene expression patterns in the cold syndrome in Chinese medicine. We identify differentially expressed genes and extracted gene modules that are enriched with differentially expressed genes in the cold syndrome by analyzing cDNA samples, which are purified from blood taken from a pedigree. Our results suggest that the cold syndrome might be caused by the physiological imbalance and/or the disorder of metabolite processes. The study confirms the hypotheses about molecular pathways responsible to human metabolic-related diseases.

Abstract
AbstractThe gene expression profile of a normal-suffering monozygotic twin pair is investigated to explore biological mechanisms of spastic type cerebral palsy. Main works include following three aspects: First, a cDNA microarray test is carried out to get the differentially expressed genes of the patient with cerebral palsy compared to her monozygotic twin sister. Second, these differentially expressed genes are searched for their bioinformation within 4 biological databases: FatiGO, FatiGOPlus, KEGG, and SOURCE. Third, a set of special genes and gene families are screened out from the spastic type cerebral palsy patient. These biological analyses reveal that those genes for cell junction are mostly down-regulated, while those genes for metabolism are mostly up-regulated. The individual genes, gene family, and their associated biological functions can reflect the pathological and physiological characteristics of the cerebral palsy.

Abstract
We have performed an analysis of a family with kidney-yang deficiency syndrome (KDS) in order to determine the structural genomic variations through a novel approach designated as “copy number variants” (CNVs). Twelve KDS subjects and three healthy spouses from this family were included in this study. Genomic DNA samples were genotyped utilizing an Affymetrix 100 K single nucleotide polymorphism array, and CNVs were identified by Copy Number Algorithm (CNAT4.0, Affymetrix). Our results demonstrate that 447 deleted and 476 duplicated CNVs are shared among KDS subjects within the family. The homologus ratio of deleted CNVs was as high as 99.78%. One-copy-duplicated CNVs display mid-range homology. For two copies of duplicated CNVs (CNV4), a markedly heterologous ratio was observed. Therefore, with the important exception of CNV4, our data shows that CNVs shared among KDS subjects display typical Mendelian inheritance. A total of 113 genes with established functions were identified from the CNV flanks; significantly enriched genes surrounding CNVs may contribute to certain adaptive benefit. These genes could be classified into categories including: binding and transporter, cell cycle, signal transduction, biogenesis, nerve development, metabolism regulation and immune response. They can also be included into three pathways, that is, signal transduction, metabolic processes and immunological networks. Particularly, the results reported here are consistent with the extensive impairments observed in KDS patients, involving the mass-energy-information-carrying network. In conclusion, this article provides the first set of CNVs from KDS patients that will facilitate our further understanding of the genetic basis of KDS and will allow novel strategies for a rational therapy of this disease.

Abstract
Objective. To explore the genetic traits of Kidney-yang deficiency syndrome (KDS). Design. Twelve KDS subjects and three spouses from a typical KDS family were recruited. Their genomic DNA samples were genotyped by Affymetrix 100K single-nucleotide polymorphism (SNP) arrays. The linkage disequilibrium (LD) SNPs were generated using GeneChip DNA analysis software (GDAS, Affymetrix). Genes located within 100 bp of the flanks of LD SNPs were mined via GeneView. 29 exons of the doublecortin domain containing 5 (DCDC5), a representative gene within the flank of an LD SNP, were resequenced. Results. Five LD SNPs display midrange linkage with KDS. Two genes with established functions, DCDC5 and Leucyl-tRNA synthetase, were mined in the flanks of LD SNPs. Resequencing of DCDC5 revealed a nonsynonymous variation, in which 3764T/A was replaced by C/G. Accordingly, the Ser1172 was substituted by Pro1172. The S1172P substitution effect was evaluated as “possibly damaging” by PolyPhen. Conclusion. We have identified a genomic variation of DCDC5 based on the LD SNPs derived from a KDS family. DCDC5 and other genes surrounding these SNPs display some relationships with key symptoms of KDS.

Abstract
In order to probe the genetic traits of Kidney-yang Deficiency Syndrome (KDS), we employed a national standard of KDS diagnosis for the collection of KDS subjects. Each candidate KDS subject from a typical family was diagnosed by 5 independent physicians of Traditional Chinese Medicine (TCM), and repeated for 3 years, all on the first Saturday of December. Fifteen samples of genomic DNA were isolated and genotyped by Affymetrix 100 K arrays of single nucleotide polymorphism (SNP). Then appropriate tools were used for the analysis of linkage disequilibrium (LD) and bioinformatic mining of LD SNPs. The results indicated that our procedure of TCM diagnosis can effectively collect KDS subjects and therefore provide substantial basis for the linkage analysis of KDS. Five SNPs (i.e. rs514207, rs1054020, rs7685923, rs10515889 and rs10516202) were identified as LD SNPs from this KDS family, representing an unprecedented set of LD SNPs derived from TCM syndrome. These SNPs demonstrate midrange linkage disequilibrium within the KDS family. Two genes with established functions were identified within 100 bp of these SNPs. One is Homo sapiens double cortin domain containing 5, which interacts selectively with mono-, di- or tri-saccharide carbohydrate and involves certain signaling cascades. Another one, leucyl-tRNA synthetase, is also a pleiotropic gene response to cysteinyl-tRNA aminoacylation and protein biosynthesis. In conclusion, KDS is involved in special SNP linkage disequilibrium in the intragenic level, and genes within the flanks of these SNPs suggest some essential symptoms of KDS. However, definitive evidence to confirm or exclude these loci and to establish their biological activities will be required.

Abstract
OBJECTIVE To explore the genetic characteristics and molecular regulator of Kidney-Yang Deficiency Syndrome (KDS). DESIGN A typical KDS family was collected using a questionnaire of cold feeling and a 40-item scoring table of KDS based on Traditional Chinese Medicine (TCM), by single-blind method repeated annually over three years. Their transcriptomes were assayed by microarray and validated by RT-PCR and ELISA. Simultaneously, 10 healthy volunteers were recruited as controls and the same protocols were performed. RESULTS This typical KDS family has 35 members, of whom 11 were evaluated as having severe KDS and 6 as having common KDS. Results of the cDNA microarray revealed that there were 420 genes/expressed sequence tags differentially expressed in KDS transcriptomes, indicating a global functional impairment in the mass-energy-information carrying network of KDS patients, involving energy metabolism, signal transduction, development, cell cycle, and immunity. Pathway analysis by gene set enrichment assay (GSEA) and other tools demonstrated that mitogenic activated protein kinase (MAPK) is among the most insufficiently activated pathways, while the oxidative phosphorylation and glycolysis/gluconeogenesis pathways, the two main pathways relevant to ATP synthesis, were among the most excessively activated pathways in KDS patients. Results of RT-PCR and ELISA confirmed the status of insufficient activity of the MAPK pathway. CONCLUSION KDS patients undergo overall attenuated functions in the mass-energy-information carrying network. The marked low level of energy output in KDS may be primarily attributed to the insufficient activity of the MAPK pathway, which may be a key monitor for the abnormal energy metabolism and other impaired activities in KDS.

Abstract
The aim of this work was to investigate the effects of ageing on rat urinary metabolites and to evaluate the anti-ageing effects of the total flavone of Epimedium (TFE). Proton nuclear magnetic resonance based metabonomic analyses was performed on urine from rats aged 4, 10, 18 and 24 months, and rats administered with TFE. By multivariate analysis, 26 characteristic resonances were found to be highly related with the age of rats, and ten of them were structurally postulated as creatinine, lactate, alanine, acetate, acetone, succinate, allantoin, methylamine, dimethylamine and trimethylamine-N-oxide; these metabolites involve creatinine metabolites, aliphatic amines metabolites and some important intermediates or end products of energy metabolism. Principal components analysis revealed that the metabolic profiles of 24-month-old rats treated with TFE closely resembled those of rats aged 18 months. In addition, most of these characteristic resonances were reset to younger levels by TFE intervention. The result suggests that TFE administration can markedly influence the ageing process and shows anti-ageing effects, which might due to the melioration of pyruyate metabolism and oxidative phosphorylation.

Abstract
OBJECTIVE To screen diagnostic markers of Deficiency-Cold syndrome by gene expression profile and to establish a discriminant mathematical milliliters model for the clinical diagnosis of this syndrome based on a support vector machine (SVM). METHODS A family suffering from Deficiency-Cold syndrome is chosen for this study. This family has 5 patients with Deficiency-Cold syndrome and 10 normal members. The peripheral blood samples for these 5 patients and 5 normal members are tested by using cDNA microarray with 18,816 clones to get their differential expression genes. These genes are further explored to understand their biological functions and pathways through existing databases. A SVM model for clinical diagnosis is then developed based on these differential expression genes. RESULTS A total of 83 differential expression genes were identified between patients and normal members, in which 21 genes were recorded in the FATIGO database and 16 genes were related to metabolism. Eight (8) pathways were sorted out in the KEGG database, and half pathways were associated with human metabolism. A discriminant mathematical model based on a support vector machine successfully predicted a normal person and a patient with heavy Deficiency-Cold syndrome based on their gene differential expression profiles. Thus, this model may classify the Deficiency-Cold syndrome. CONCLUSION This work demonstrates that the differential expression genes can be used to identify normal persons and patients with Deficiency-Cold syndrome. Deficiency-Cold syndrome is mainly associated with the metabolism-related gene regulations. In addition, the discriminant mathematical model based on a support vector machine is applicable to the clinical diagnosis for Deficiency-Cold syndrome.
