Twelve-component pharmacokinetic study of rat plasma after oral administration of You-Gui-Wan in osteoporosis rats with kidney-yin deficiency and kidney-yang deficiency.

You-Gui-Wan is a widely used traditional Chinese medicine preparation for the treatment of osteoporosis with kidney-yang deficiency, and is composed of both yang-invigorating and kidney-tonifying herbs, and yin-nourishing and kidney essence-replenishing herbs. Considering that the pharmacokinetics of drugs might differ in different pathological conditions, it is necessary to study the pharmacokinetic characteristics of You-Gui-Wan under different osteoporotic conditions. In this study, the pharmacokinetic behaviors of You-Gui-Wan in osteoporosis rats with kidney-yin and kidney-yang deficiency were compared. The results showed that the absorption, metabolism, and disposition of You-Gui-Wan varied widely in animals with different types of osteoporosis. The active components belonging to the yang-invigorating herbs, such as aconitine, hypaconitine, mesaconitine, benzoylaconine, benzoylhypacoitine, benzoylmesaconine, chlorogenic acid and pinoresinol diglucoside, had a higher uptake and slower elimination in osteoporosis rats with kidney-yang deficiency, which corresponds to the opinion that You-Gui-Wan is used to treat kidney-yang deficiency syndrome, and indicates the scientific nature of Bian-Zheng-Lun-Zhi.

A New Method for Syndrome Classification of Non-Small-Cell Lung Cancer Based on Data of Tongue and Pulse with Machine Learning.

OBJECTIVE: To explore the data characteristics of tongue and pulse of non-small-cell lung cancer with Qi deficiency syndrome and Yin deficiency syndrome, establish syndrome classification model based on data of tongue and pulse by using machine learning methods, and evaluate the feasibility of syndrome classification based on data of tongue and pulse. METHODS: We collected tongue and pulse of non-small-cell lung cancer patients with Qi deficiency syndrome (n = 163), patients with Yin deficiency syndrome (n = 174), and healthy controls (n = 185) using intelligent tongue diagnosis analysis instrument and pulse diagnosis analysis instrument, respectively. We described the characteristics and examined the correlation of data of tongue and pulse. Four machine learning methods, namely, random forest, logistic regression, support vector machine, and neural network, were used to establish the classification models based on symptom, tongue and pulse, and symptom and tongue and pulse, respectively. RESULTS: Significant difference indices of tongue diagnosis between Qi deficiency syndrome and Yin deficiency syndrome were TB-a, TB-S, TB-Cr, TC-a, TC-S, TC-Cr, perAll, and the tongue coating texture indices including TC-CON, TC-ASM, TC-MEAN, and TC-ENT. Significant difference indices of pulse diagnosis were t4 and t5. The classification performance of each model based on different datasets was as follows: tongue and pulse < symptom < symptom and tongue and pulse. The neural network model had a better classification performance for symptom and tongue and pulse datasets, with an area under the ROC curves and accuracy rate which were 0.9401 and 0.8806. CONCLUSIONS: It was feasible to use tongue data and pulse data as one of the objective diagnostic basis in Qi deficiency syndrome and Yin deficiency syndrome of non-small-cell lung cancer.

miRNA Expression Profile of Saliva in Subjects of Yang Deficiency Constitution and Yin Deficiency Constitution.

BACKGROUND/AIMS: Based on the theory of constitution in Traditional Chinese Medicine (TCM), the Chinese Han population has been classified into nine constitutions. Of these, Yang deficiency constitution mainly exhibit cold intolerance while Yin deficiency constitution mainly exhibit heat intolerance. Some studies have been carried out to explore the modern genetic and biological basis of such constitution classification, but more remains to be done. MicroRNA (miRNA) serves as post-transcriptional regulators of gene expression and may play a role in the classification process. Here, we examined miRNA expression profile of saliva to further improve the comprehensiveness of constitution classification. METHODS: Saliva was collected from Chinese Han individuals with Yang deficiency, Yin deficiency and Balanced constitutions (n=5 each), and miRNA expression profile was determined using the Human miRNA OneArray®v7. Based on 1.5 Fold change, means log2|Ratio|≥0.585 and P-value< 0.05, differentially expressed miRNA was screened. Target genes were predicted using DIANA-TarBasev7.0 and analysis of KEGG pathway was carried out using DIANA-mirPathv.3. RESULTS: We found that 81 and 98 differentially expressed miRNAs were screened in Yang deficiency and Yin deficiency constitution, respectively. Among them, 16 miRNAs were identical and the others were unique. In addition, the target genes that are regulated by the unique miRNAs were significantly enriched in 27 and 20 signaling pathways in Yang deficiency and Yin deficiency constitution, respectively. Thyroid hormone signaling pathway is present in both constitutions. These unique miRNAs that regulated target genes of thyroid hormone signaling pathway may be associated with cold intolerance or heat intolerance. CONCLUSION: The results of our study show that Yang deficiency and Yin deficiency constitutions exhibit systematic differences in miRNA expression profile. Moreover, the distinct characteristics of TCM constitution may be explained, in part, by differentially expressed miRNAs.

Bone marrow angiogenesis in patients presenting with differential Chinese medicine syndrome: correlation with the clinico-pathological features of aplastic anemia.

OBJECTIVE: To explore differences in bone marrow angiogenesis seen in aplastic anemia (AA) patients presenting with differential Chinese medicine (CM) syndrome, and to correlate these differences with clinical pathology. METHODS: Thirty-five patients were enrolled, including 18 with "yang deficiency syndrome" and 17 with "yin deficiency syndrome." Bone marrow biopsies and serum were collected. Microvessel density (MVD) and positive expression of vascular endothelial-derived growth factor (VEGF) were detected by immunohistochemisty. Hypoxia inducible factor -1α (HIF-1α), and VEGF expression were assayed by enzyme-linked immunoabsorbent assay (ELISA), serum lactate dehydrogenase (LDH) was tested by enzyme method and liquid chip technology was used to detected the expression of interleukin (IL)-2, IL-4, IL-6, IL-10, interferon (IFN)-γ and tumor necrosis factor (TNF)-α. RESULTS: Counts for leukocytes, absolute neutrophils and platelets in "yin deficiency syndrome" were lower than those found in "yang deficiency syndrome" (P<0.05). MVD and VEGF expression, and the positive rate of CD34 and VEGF in bone marrow were lower in AA, especially in "yin deficiency syndrome" (P<0.01 or P<0.05). "Yin deficiency syndrome" displayed decreased VEGF and LDH expression, and enhanced expression of HIF-1α as compared to "yang deficiency syndrome" (P<0.05). Levels of IL-4 and IL-6 were higher in AA (P<0.01), but IL-10 was decreased (P<0.05). High TNF-α expression was seen in "yang deficiency syndrome" and IFN-γ expression was decreased in "yin deficiency syndrome" as compared with normals (P <0.01 and P<0.05, respectively). CONCLUSION: AA patients have lower MVD than normals, especially in "yin deficiency syndrome." MVD might differentially correlate to disease severity, and could be dependent on bone marrow or serum VEGF expression and LDH. Additionally, IL-2, IL-10, IL-4 and IFN-γ were negatively associated while IL-6 and TNF-α were positively associated with MVD.

[Analysis of associated rules between Chinese medical syndrome typing features of epigastric pain and endoscopic features].

OBJECTIVE: To explore Chinese medical syndrome typing features of epigastric pain and its association with gastroscopic manifestations. METHODS: Using associated rules data mining method, an analysis study was performed in 234 patients with epigastric pain by combining holistic Chinese medical syndrome typing and results of gastroscopic examinations. RESULTS: Pi-Wei deficiency cold syndrome (PWDCS) was associated with pale gastric mucosa, or superficial ulcers accompained with unobvious redness and swelling. Inversed Gan-qi invading Wei syndrome (IGIWS) was associated with bile regurgitation. Damp-heat stagnating in the middle jiao syndrome (DSMJS) was associated with obvious redness and swollen mucosa, or ulcers accompanied with yellow and white fur. Wei-yin exhaustion syndrome (WYES) was associated with coarse mucosa and exposed blood vessels, or rare mucus. Retention of blood stasis in Wei syndrome was associated with bulged swelling and erosion. Indigestion impairing Wei syndrome (IIWS) was associated with retention of water and food, or more mucus attached. The endoscopic manifestations of PWDCS and DSMJS occurred most frequently, while PWDCS and IGIWS ranked the first place in macroscopic Chinese medical syndrome typing. CONCLUSIONS: The manifestations of endoscopic features were closely associated with Chinese medical syndrome typing. The syndrome typing features of epigastric pain could be objectively and further grasped by summarizing syndrome typing laws using modern devices such as gastroscopic examinations, thus improving the accuracy of clinical syndrome typing.

Comfortable lifestyle-induced imbalance of neuro-endocrine-immunity network: a possible mechanism of vascular endothelial dysfunction.

OBJECTIVE: To observe the changes of vascular endothelial functions and general neuro-endocrine-immunity (NEI) network under the state of qi-deficiency syndrome induced by excessive idleness and to approach their internal relevance and illuminate initially the pathophysiological mechanism of vascular lesion induced by excessive idleness. METHODS: A total of 100 male Wistar rats were randomly divided into the control group and the qi-deficiency syndrome model group, 50 rats in each group. The qi-deficiency syndrome model was established by feeding the animals with hyper-alimentation diet in combination with restricting movement for 10 weeks. Changes of common chemical signal molecules related to NEI and vascular endothelial functions were measured by the end of the experiment. Furthermore, their internal relevance was analyzed by the method of canonical correlation analysis. RESULTS: The vascular endothelial structure and function were obviously injured in the model group. Compared with the control group, the chemical signal molecules, such as 5-hydroxytryptamine (5-HT), corticosterone (CORT), triiodothyronine (T3), tetraiodothyronine (T4), angiotensin II (Ang II), interleukin-1 (IL-1), and tumor necrosis factor-alpha (TNF-alpha) in peripheral blood of the model group (n=43) were changed significantly (P<0.05 or P<0.01). Canonical correlation analysis showed that vascular endothelial dysfunction was correlated to the changes of these signal molecules in the NEI network. CONCLUSIONS: Comfort-based lifestyle induced not only vascular endothelial dysfunction but also an imbalance of the NEI network. Vascular endothelial dysfunction and the imbalanced NEI network interacted with each other, and an imbalance of the NEI network may be the pathophysiologic basis for the genesis and development of vascular endothelial dysfunction, even diseases of the blood vessel.

Metabonomic phenotype and identification of "heart blood stasis obstruction pattern" and "qi and yin deficiency pattern" of myocardial ischemia rat models.

The traditional Chinese medicine concepts of "Xinxueyuzuzheng (heart blood stasis obstruction pattern)" and "Qiyinliangxuzheng (qi and yin deficiency pattern)" for myocardial ischemia rat models were constructed in the present study. Endogenous metabolites in rat plasma were analyzed using the GC/TOF-MS-based metabonomic method. Significant metabolic differences were observed between the control and two model groups, and the three groups were distinguished clearly by pattern recognition. Compared with those of the control, the levels of hydroxyproline, threonic acid, glutamine and citric acid were strikingly up- or down-regulated in model rats. The metabolites contributing most to the classification between the two "pattern" rats were identified, such as valine, serine, threonine, ornithine, hydroxyproline, lysine, 2-hydroxybutanoic acid, 3-hydroxybutanoic acid, galactofuranose and inositol. These compounds were indicated as the potential biomarkers. The results suggested that the two "patterns" are involved in dysfunction in oxidative stress, energy metabolism and amino acid metabolism. These findings also provided the substantial foundation for exploring the scientific connotation of these two "Zhengxing (pattern types)" of myocardial ischemia, and "Bianzheng (pattern identification)".

Relationship between various Chinese medicine types and T-cell subsets in patients with ulcerative colitis.

OBJECTIVE: To investigate the relationship between various Chinese medicine (CM) types and T-cell subsets (CD4(+) and CD8(+)) in the colonic mucous membranes of patients with ulcerative colitis (UC). METHODS: Fifty UC patients were enrolled, after differentiation into four types by CM syndromes, i.e., the internal heat-damp accumulation type (IHDA), the qi-stagnancy with blood stasis type (QSBS), the Pi-Shen yang-deficiency type (PSYD) and the yin-blood deficiency type (YBD). From every patient, 3-5 pieces of intestinal mucous membrane tissues were taken through colonoscopy to determine the levels of the T-cell subsets (CD4(+) and CD8(+)) using immunohistochemical method. The results were compared with those in the normal control. RESULTS: The level of CD8(+)increased and the ratio of CD4(+)/CD8(+)decreased mainly in colonic mucous membranous tissues in UC patients. The level of CD4(+)decreased significantly in IHDA types (P<0.01), but decreased only slightly in the PSYD, QSBS and YBD types. CD8(+)increased significantly in the IHDA types (P<0.01), but only slightly in the other three types. CONCLUSION: The IHDA types of UC are closely related with T-cell subsets. The difference of T-cell subsets in various IHDA types of UC patients has provided a theoretical basis for syndrome differentiation in the CM typing of UC.

[Study on immunological pathogenesis of 59 patients with multiple sclerosis of different TCM syndrome types].

OBJECTIVE: To explore the immunological pathogenesis of multiple sclerosis (MS) patients of different TCM syndrome types. METHODS: Fifty-nine MS patients were assigned to two types by syndrome typing according to their clinical manifestations, the Gan-Shen yin-deficiency (GSYD, 40 cases) type and the both yin-yang deficiency (YYD, 19 cases) type. Difference of patients' age of first attack, times of relapsing, duration of disease, MRI finding and evoked potential between the two groups were compared. The immunology indexes were also compared in part of the patients (26 cases in GSYD type and 12 cases in YYD type). RESULTS: The age of first attack was later (P < 0.01), level of myelin basic protein in cerebrospinal fluid was higher (P < 0.05), in the YYD type than those in the GSYD type. Besides, the relapsing time in GSYD type, and the blood-brain barrier index and level of myelin basic protein in YYD type showed an ascending trend (P = 0.056, 0.074, 0.093, respectively). CONCLUSION: Immunological difference exists between the MS patients of GSYD type and those of YYD type.

[Study on correlation between TCM syndrome type and pathological changes of liver tissue in 260 patients with chronic hepatitis B].

OBJECTIVE: To study the correlation between TCM syndrome type and liver tissue pathological changes in patients with chronic hepatitis B (CHB) in order to provide evidence for syndrome differentiation. METHODS: Syndrome typing as well as liver pathological grading and staging of liver biopsy were performed on 260 patients with CHB, then the relationship between them was analyzed. RESULTS: (1) The grade of liver inflammation was mainly G1 and G2 in patients of Gan-qi stagnation and Pi-deficiency type (type 1); G2 in patients of inner damp-heat retention type (type II); G3 in patients of Gan-Shen yin-deficiency type (type lII) and Pi-Shen yang-deficiency type (type IV); while G4 occurred mainly in patients of blood stasis blocking collateral type (type V), showing significant difference as compared with other syndrome types. (2) The liver pathological stage in patients of type I and II was mainly S1 and S2, while S3 and S4 occurred mainly in patients of type III and type IV. (3) The pathological change was mainly G3-G4 and S3-S4 in blood stasis syndrome, while it was mainly G1-G2 and S1-S2 in non-blood stasis syndrome. CONCLUSION: The TCM syndrome type is correlated with liver tissue pathological change to certain extent, among them, syndrome with or without blood stasis showed the closest correlation. The syndrome type of CHB patients developed, along with the aggravating of liver pathological injury, from sthenia to asthenia, from qi to blood, and finally to the blood stasis blocking collateral. So the treatment should be lay stress on activating blood circulation to remove stasis, and be implemented by 3 stages.

[Multicentered, randomized, controlled clinical trial on patients with IgA nephropathy of Qi-yin deficiency syndrome type].

OBJECTIVE: To evaluate the effect and safety of Chinese medicine Compound Shenhua Tablet (SHT) on IgA nephropathy patients of TCM Qi-yin deficiency syndrome type, by using angiotensin-converting enzyme inhibitors (ACEI) fosinopril as the positive control. METHODS: Adopting prospective, multicentered, double-blinded, double-dummy, randomized, controlled trial design, 131 patients with IgA nephropathy of Qi-yin deficiency syndrome type were assigned to two groups, the 65 patients in the treated group (SHG) and the 66 in the control group treated with SHT and fosinopril respectively for 12 weeks. The indexes of efficacy, including TCM syndrome scores, urinary protein, serum creatinine, urea nitrogen and endogenous creatinine clearance rate, as well as the indexes of safety, including liver function and occurrence of adverse events were observed. RESULTS: There was no significant statistical difference between the two groups in aspects of baseline demographic characteristics and clinical figures, including gross hematuria, hypertension, incidence of renal insufficiency, total course of disease, urinary protein, TCM syndrome score, renal pathological Katafuchi score, glomerular score, tubular-interstitial score, vascular score and Lee grading. Afte 12 weeks of treatment, the content of 24-h urinary protein significantly decreased by 0.26 +/- 0.95 g/24 h and 0.26 + 0.92 g/24 h respectively in the two groups, showing significant difference in comparing with baseline, but insignificant difference between the two groups (P > 0.05); the scores of TCM dominant syndromes in them decreased by 2.52 +/- 2.34 scores and 1.74 +/- 2.12 scores respectively with significant difference as compared with baseline (P < 0.01), and in comparison between groups (P < 0.05). No significant change in levels of serum creatinine, urea nitrogen, endogenous creatinine clearance rate in both groups was found (P > 0.05). Scores of TCM accompanied syndromes in the two groups was significantly decreased (P < 0.01), but the difference between them was insignificant (P > 0.05). No severe adverse event occurred during treatment, and the occurrence in the two groups was similar. CONCLUSION: SHT, just like the positive control medicine fosinopril, can effectively decrease the proteinuria and improve clinical syndrome of IgA nephropathy patients of Qi-yin deficiency syndrome type, and shows no serious adverse reaction.

[Relationship of plasma endotoxin level with TCM deficiency/excess syndrome and grading/staging of pathologic change of liver in patients with chronic hepatitis].

OBJECTIVE: To explore the relationship of plasma endotoxin level with TCM deficiency/excess Syndrome and the grading/staging of pathologic change of liver in patients with chronic hepatitis B (CHB). METHODS: Plasma level of endotoxin (ET) was determined using chromogenic limulus amebocyte lysate (LAL) assay in 75 patients with chronic hepatitis B (30 of excess dominance, 45 of deficiency dominance) and also in 15 healthy subjects for control. Moreover, pathological examination on liver biopsy of 20 patients was conducted. RESULTS: (1) ET level increased in all CHB patients, and the increment was higher in patients of excess dominance than that in patients of deficiency dominance, showing significant difference (P < 0.01). (2) Correlation between ET level and liver pathological grading/staging was shown in CHB patients. CONCLUSION: Plasma level of ET could be taken as one of the criteria of TCM microcosmic diagnosis in differentiating deficiency/excess syndrome. (2) Endotoxemia plays an important role in pathologic process of liver injury.

[Multicenter prospective study on relationship of TCM syndrome type and renal pathology in 286 patients with IgA nephropathy].

OBJECTIVE: To study the distribution pattern of TCM Syndrome type and its relationship with renal pathology in patients with IgA nephropathy. METHODS: Apopting multicenter coordinated method, patients' TCM Syndrome type was differentiated according to their clinical manifestations, data concerning laboratory examination and renal pathology were collected to establish a database for analyzing the relationship between TCM Syndrome type and renal pathology in 286 patients. RESULTS: Patients of Pi-Fei Qi-deficiency type (type 1) and both Qi-Yin deficiency type (type 2) showed rather milder pathological changes, by Lee classification, most of them belonged to grade I-III (72.3%, 70.2%); patients of Gan-Shen Yin deficiency type (type 3) had severe pathological change and majority of them belonged to grade III-IV (84.6%); and the most severe pathological change was shown in patients of Pi-Shen Yang-deficiency type (type 4), and the Lee's grade IV-V was dominant (88.0%) in them. Syndrome type of patients was significantly correlated with their Lee's grade (r = 0.26, P < 0.01). Percentage of glomerular sclerosis in patients of type 4 was higher than that in patients of the other three types. Semi-quantitative scoring upon pathological changes showed that the total, glomerular, tubulo-interstitial and vascular scores were significantly higher in patients of type 4 than in those of the other three types; those scores were higher in patients of type 3 than in type 1; the total, glomerular and vascular scores were higher in patients of type 3 than in type 2; and scores in patients of type 1 and type 2 showed insignificant difference. CONCLUSION: Multicentric prospective study proves that the TCM Syndrome typeof patients with IgA nephropathy is significantly correlated with the grade and severity of their renal pathological changes, thus, the TCM Syndrome typing shows definite referential importance to conclude the severity of renal pathological change in patients with IgA nephropathy.

[Histocytopathological study on gastric mucosa of spleen deficiency syndrome].

OBJECTIVE: To explore the pictures of gastric mucosa of Spleen deficiency syndrome, and the relationship between the degree of pathological changes of gastric mucosa and types of Spleen deficiency syndrome. METHODS: One hundred and eighty-eight Spleen deficiency patients with organic diseases of heart, lung, liver, gallbladder, pancreas, intestine and kidney excluded were examined their gastric mucosa. Tests of histopathology and subcellular ultrastructure were conducted by using optical microscope, electron scanning microscope, electron transmission microscope and histochemical staining methods. RESULTS: The gastric mucosa of Spleen Qi deficiency and Spleen Yang deficiency patients could either be affected with organic lesion (type G) or unaffected (type F); the gastric mucosa of Spleen Yin deficiency and Spleen deficiency with Qi stagnation were both affected by gastric lesions, and the degree of their lesions was more serious than that of Spleen Qi deficiency of type G and Spleen Yang deficiency of type G, P < 0.05-0.01. CONCLUSION: Pathological changes did not necessarily occur in the gastric mucosa of Spleen deficiency patients; the degree of pathological changes was relevant with the evolution of Spleen deficiency types.

[Preliminary study on relationship between syndrome differentiation of esophageal cancer and changes of exfoliated cells of tongue coating].

Exfoliated cells of tongue coating of 63 esophageal cancer (EC) cases have been investigated by applying exfoliate cytologic examination, which showed that abnormal cornified cells were commonly seen while they were less in the patients of EC than those in the healthy group, and their difference was significant (P < 0.05), It showed an increase mainly in the number of pro-cornified cells in the patient of the Qi-Yang Deficiency group, an increase mainly in completely cornified cells in the Yin Deficiency and an increase in both pro-cornified cells and completely cornified cells in Phlegn-Dampness and blood Stasis patients. The difference among four groups was significant (P < 0.05). The changes of exfoliated cells of tongue coating provided an objective index for the early diagnosis of EC.
