RESUMEN
BACKGROUND: Clinical practice guidelines (CPGs) for Chinese medicine (CM) are being developed to assist doctors with appropriate decisions concerning CM care. To date, there has been little investigation on the perspectives of those to whom the guidelines are directed. METHODS: A self-administered questionnaire was sent to 4503 doctors in 28 provinces of China in the latter half of 2012. Questions were organized around the topics of knowledge, application, practice changes, beliefs and outcomes of implementation. Basic classificatory data on specialties and years of qualification were also collected. RESULTS: Replies were received from 4495 CM doctors (99.82%). Of these, 85.56% of CM doctors reported being familiar with CPG recommendations, but the overall adherence rate was only 50.39%. The length of time practicing CM may influence the rate of adherence, since 709 doctors (51.90%) with less than 5 years of experience reported never having followed CPGs. Doctors in nine specialties showed a modest degree of homogeneity in their attitudes towards CM diagnosis and treatment, which were generally positive. Most doctors regarded CPG-recommended therapies as safe (92%), economic (84%), and effective (76%). Approximately four-fifths of those questioned selected 'acceptable' (60.84%) and 'acceptable after revision' (19.23%) regarding their comprehensive assessment of the CPGs. CONCLUSIONS: An encouraging result from this survey is that the majority of CM doctors support the concept of CPGs for the practice of CM. However, the results of this survey also suggest that improving the adherence of CM doctors to the guidelines remains a major challenge to improving the practice standards for CM.

BACKGROUND: Growing evidence shows that herb medicines have some anti-osteoporotic effects, the mechanism underlying is unknown. This study aims to investigate the therapeutic effect of Chinese herb supplements on rats that had osteoporosis-like symptom induced by ovariectomy (OVX). METHODS: OVX or sham operations were performed on virgin Wistar rats at three-month old, which were randomly divided into eight groups: sham (sham); OVX control group (OVX); OVX rats with treatments [either diethylstilbestrol (DES) or Semen Astragali Complanati decoction (SACD) or Rhizoma Cibotii decoction (RCD) or Herba Cistanches decoction (HCD) or Semen Allii Tuberosi decoction (SATD)]. Non-surgical rats were served as a normal control (NC). The treatments began 4 weeks after surgery, and lasted for 12 weeks. Bone mass and its turnover were analyzed by histomorphometry. Levels of protein and mRNA of osteoprotegerin (OPG) and receptor activator of nuclear factor κB ligand (RANKL) in osteoblasts (OB) and bone marrow stromal cells (bMSC) were evaluated by immunohistochemistry and in situ hybridization. RESULTS: Compared to OVX control, TBV% in both SACD and RCD groups was increased significantly, while TRS%, TFS%, MAR, and mAR were decreased remarkably in the SACD group, only TRS% decreased dramatically in the RCD group. No significant changes in bone formation were observed in either HCD or SATD groups. OPG levels in both protein and mRNA were reduced consistantly in OB and bMSC from OVX control rats, in contrast, RANKL levels in both protein and mRNA were increased significantly. These effects were substantially reversed by treatments with either DES or SACD or RCD. No significant changes in both OPG and RANKL expression were observed in OB and bMSC from OVX rats treated with SATD and HCD. CONCLUSIONS: Our study showed that SACD and RCD increased bone formation by stimulating OPG expression and downregulating RANKL expression in OB and bMSC. This suggests that SACD and RCD may be developed as alternative anti-osteoporotic agents for therapy of postmenopausal osteoporosis.

The research is aimed to explore the distinct molecular signatures in discriminating the rheumatoid arthritis patients with traditional Chinese medicine (TCM) cold pattern and heat pattern. Twenty patients with typical TCM cold pattern and heat pattern were included. Microarray technology was used to reveal gene expression profiles in CD4+ T cells. The signal intensity of each expressed gene was globally normalized using the R statistics program. The ratio of cold pattern to heat pattern in patients with RA at more or less than 1:2 was taken as the differential gene expression criteria. Protein-protein interaction information for these genes from databases was searched, and the highly connected regions were detected by IPCA algorithm. The significant pathways were extracted from these subnetworks by Biological Network Gene Ontology tool. Twenty-nine genes differentially regulated between cold pattern and heat pattern were found. Among them, 7 genes were expressed significantly more in cold pattern. Biological network of protein-protein interaction information for these significant genes were searched and four highly connected regions were detected by IPCA algorithm to infer significant complexes or pathways in the biological network. Particularly, the cold pattern was related to Toll-like receptor signaling pathway. The following related pathways in heat pattern were included: Calcium signaling pathway; cell adhesion molecules; PPAR signaling pathway; fatty acid metabolism. These results suggest that better knowledge of the main biological processes involved at a given pattern in TCM might help to choose the most appropriate treatment.

Better effectiveness would be achieved when interventions are used in treating patients with a specific traditional Chinese medicine (TCM) pattern. In this paper, the effectiveness in treating rheumatoid arthritis (RA) patients in a randomized clinical trial as reanalyzed after the patients were classified into different TCM patterns and the underlying mechanism of how the TCM pattern influences the clinical effectiveness of interventions (TCM and biomedicine therapy) was explored. The pharmacological networks of interventions were builtup with protein and protein interaction analyses based on all the related targeted proteins obtained from PubChem. The underlying mechanism was explored by merging the pharmacological networks with the molecular networks of TCM cold and hot patterns in RA. The results show that the TCM therapy is better in treating the RA patients with TCM hot pattern, and the biomedical therapy is better in the RA patients with cold pattern. The pharmacological network of TCM intervention is merged well with the molecular network of TCM hot pattern, and the pharmacological network of biomedical therapy is merged well with the network of cold pattern. The finding indicates that molecular network analysis could give insight into the full understanding of the underlying mechanism of how TCM pattern impacts the efficacy.
RESUMEN
IN TRADITIONAL CHINESE MEDICINE (TCM), PATIENTS WITH RHEUMATOID ARTHRITIS (RA) CAN BE CLASSIFIED INTO TWO MAIN PATTERNS: cold-pattern and heat-pattern. This paper identified the network-based gene expression biomarkers for both cold- and heat-patterns of RA. Gene expression profilings of CD4+ T cells from cold-pattern RA patients, heat-pattern RA patients, and healthy volunteers were obtained using microarray. The differentially expressed genes and related networks were explored using DAVID, GeneSpring software, and the protein-protein interactions (PPI) method. EIF4A2, CCNT1, and IL7R, which were related to the up-regulation of cell proliferation and the Jak-STAT cascade, were significant gene biomarkers of the TCM cold pattern of RA. PRKAA1, HSPA8, and LSM6, which were related to fatty acid metabolism and the I-κB kinase/NF-κB cascade, were significant biomarkers of the TCM heat-pattern of RA. The network-based gene expression biomarkers for the TCM cold- and heat-patterns may be helpful for the further stratification of RA patients when deciding on interventions or clinical trials.
RESUMEN
This multicenter, randomized, controlled clinical study was designed to address the effectiveness of combined traditional-Chinese-medicine- (TCM-) based psychotherapy and Chinese herbal medicine (CHM) in the treatment of menopausal syndrome. Altogether 424 eligible women diagnosed as menopausal syndrome and categorized as Kidney-Yin/Kidney-Yang deficiency pattern in TCM were randomly assigned into 4 groups and accepted TCM-based psychotherapy (PSY), CHM, PSY + CHM, or placebo therapies, respectively, for 12 weeks, and another 12 weeks were taken as the followup. Kupperman Index (KI) and the Menopause-Specific Quality of Life (MENQOL) with its four subscales (vasomotor, physical, psychosocial, and sexual) were employed for efficacy assessment. Results showed that 400 participants completed 12-week treatment, of which 380 finished the record of KI and MENQOF at week 24. The average adjusted number of KI score decreased between baseline and 12 weeks in all groups. Statistically significant differences were detected in the average adjusted change between the PSY + CHM group and placebo at overall time points (P < 0.05). No severe adverse events occurred in each group and no significant differences were indicated between any of the three groups and placebo in adverse event proportion. We concluded that TCM psychotherapy combined with CHM has a favorable outcome in treating menopausal syndrome.
RESUMEN
BACKGROUND: The objective of this study was to evaluate the effects of herbal medicines, such as Radix Dipsaci (RDD), Pyrola Herb (PHD), and Cynomorium songaricum decoction (CSD), on osteoporotic rats induced by ovariectomy (OVX). METHODS: OVX or sham operations were performed on 69 virgin Wistar rats that were divided into six groups: sham (sham, n = 12), OVX control group (OVX, n = 12), and OVX rats with treatments (diethylstilbestrol, E2, n = 12; RDD, n = 11, PHD, n = 11, and CSD, n = 11). Non-surgical rats served as normal control (NC, n = 12). The treatments began four weeks after surgery and lasted for 12 weeks. Bone mass and bone turnover were analyzed by histomorphometry. Levels of protein expression and mRNA of OPG and RANKL in osteoblasts (OB) and bone marrow stromal cells (bMSC) were evaluated by immunohistochemistry and in situ hybridization. RESULTS: Compared to NC and sham rats, trabecular bone formation was significantly reduced in OVX rats, but restored in E2-treated rats. Treatment with either RDD or PHD enhanced trabecular bone formation remarkably. No significant change of bone formation was observed in CSD-treated rats. OPG expression of protein and mRNA was reduced significantly in OB and bMSC of OVX control rats. RANKL expression of protein and mRNA was increased significantly in OB and bMSC of OVX control rats. These effects were substantially reversed (increased in OPG and decreased in RANKL) by treatment with E2, RDD, or PHD in OB and bMSC of OVX rats. No significant changes in either OPG or RANKL expression were observed in OB and bMSC of OVX rats treated with CSD. CONCLUSIONS: Our study showed that RDD and PHD increased bone formation by stimulating overexpression of OPG and downregulation of RANKL in OB and bMSC. This suggests that RDD and PHD may be used as alternative therapeutic agents for postmenopausal osteoporosis.

OBJECTIVE: H1N1 was a new and potentially serious infectious disease, in human, the severity of influenza can vary from mild to severe, thus to find an effective and safety way to control the influenza pandemic is of crucial importance. This retrospective study describes the duration of viral shedding in H1N1 patients that were hospitalized and treated in China. METHODS: Clinical data were collected from May to July, 2009 in China for 963 patients with influenza A (H1N1) virus infection. Patients were treated based on the guidelines issued by the Chinese Ministry of Health. The primary outcome was duration of viral shedding and statistical comparisons were performed. RESULTS: In the patients with body temperature greater than 38.0 degrees C, there were no differences in virus shedding duration among the patients taking oseltamivir within two days, patients undergoing Traditional Chinese Medicine (TCM) therapy or those receiving no drug therapy. In patients with body temperature > or =38.1 degrees C, TCM therapy reduced the viral shedding duration (P < 0.05, vs. oseltamivir therapy). Furthermore, taking oseltamivir two days after onset of symptoms might prolong the virus shedding duration (P < 0.05, vs. taking oseltamivir less than 2 days of onset). CONCLUSION: TCM therapy is effective for reducing the length of virus shedding in patients with body temperature > or =38.0 degrees C. Oseltamivir used for reducing virus shedding duration should be taken within two days of onset.

OBJECTIVE: The extraarticular symptoms are important in the pattern differentiation of traditional Chinese medicine (TCM), and the present study is designed in an attempt to find the associations between the extraarticular symptoms and American College of Rheumatology (ACR) Response in 194 cases of rheumatoid arthritis (RA) treated with biomedicine. METHODS: The data were obtained from a randomized clinical trial. One hundred ninety-four RA patients were treated with the biomedical therapy (diclofenec, methotrexate and sulfasalazine). ACR20 response in 24 weeks was used for the efficacy evaluation. Eighteen symptoms (including 13 extraarticular symptoms) that TCM practitioners focus on were collected for exploration on the association between the symptoms and the efficacy of the biomedical therapy with association rules method. RESULTS: After 24 weeks, a total of 135 patients receiving biomedicine had achieved an ACR20 response. The association rules analysis on each symptom showed that soreness in the waist was more associated with ACR20 response, but with lower support (selected sample size based, 20.10% and 14.95% respectively); cold intolerance and cold joint were found to be associated with ACR20 response with higher support (48.97% and 53.61% respectively), and the confidences (predicted effective rate) were 73.08% and 71.23% respectively. The associations between combination of symptoms (among them, there was at least one extraarticular symptom) and ACR20 response indicated that cold intolerance or cold joint with higher confidence and support were the most important extraarticular symptoms. CONCLUSION: The RA patients with "cold intolerance" and "cold joints", which are the extraarticular symptoms that TCM practitioners focus on, may show higher ACR20 response when treated with the biomedical approach.

OBJECTIVE: To establish a rat model of rheumatoid arthritis (RA) with kidney deficiency syndrome. METHODS: A total of 110 six-week-old specific pathogen-free male and female Sprague-Dawley rats were randomly divided into normal control group, sham-operated group, collagen-induced arthritis (CIA) control group, castration plus CIA group and hydroxyurea plus CIA group. Testiculus or ovary of rats in the castration plus CIA group was cut off, respectively. Rats in the hydroxyurea plus CIA group were given 375 mg/(kg·d) hydroxyurea by gavage administration for 17 d. Then rats in the CIA control group, castration plus CIA group and hydroxyurea plus CIA group were subcutaneously injected with mixture of type II collagen and incomplete Freund's adjuvant to induce rheumatoid arthritis. General state, arthritis index and joint swelling of the rats were observed to evaluate the onset of CIA. Contents of anti-type II collagen antibody, interleukin-6 (IL-6), IL-10, interferon-γ (IFN-γ) and corticosterone (CORT) in plasma were detected by enzyme-linked immunosorbent assay, and adrenal cyclic adenylic acid (cAMP) and cyclic guanylic acid (cGMP) levels were detected by radioimmunoassay. RESULTS: Compared with the CIA control group, the degrees of joint swelling and joint damage were significantly increased in the kidney-deficiency CIA rats (castration plus CIA group and hydroxyurea plus CIA group), with kidney deficiency syndrome similar to human clinical symptoms, such as depressed, bowed back, dullness, reduced diet and perianal contamination; the rats in those two groups were noted with a significantly decreased ratio of cAMP/cGMP; the content of CORT was increased in male rats while decreased in female rats, with an obvious increase in the content of anti-type II collagen antibody; the contents of IFN-γ, IL-6 and IL-10 were obviously increased in the castration plus CIA group. CONCLUSION: The rat model of RA with kidney deficiency syndrome has both obvious kidney deficiency syndrome and characteristics of RA and can reflect part of the patient's characteristics. However, castration is more suitable for inducing RA with kidney deficiency syndrome in rats.

BACKGROUND: Leflunomide (LEF) is a first-line disease-modifying antirheumatic drug (DMARD) for rheumatoid arthritis (RA). However, there are still a few nonresponders. It is logical to suggest that employing combinations including LEF that produce synergistic effects in terms of pharmacological activity is a promising strategy to improve clinical outcomes. METHODS: We propose a novel approach for predicting LEF combinations through investigating the potential effects of drug targets on the disease signaling network. We first constructed an RA signaling network with disease-associated driver genes. Thousands of available FDA-approved and investigational compounds were then selected based on a drug-RA network, which was generated using an algorithm model named synergistic score that combines chemical structure, functional prediction and target pathway. We then validated our predicted combination in a prospective clinical trial. RESULTS: Ligustrazine (LIG), a key component of the Chinese herb Chuanxiong and an approved drug in China, ranked first according to synergistic score. In the clinical trial, after 48 weeks, the American College of Rheumatology (ACR) 20 response rate was significantly lower (P < 0.05) in the LEF group [58.8% (45.4%, 72.3%)] than in the LEF + LIG group [78.7% (68.5%, 89.0%)]. Consistently, the erosion score was lower in patients treated with LEF + LIG than in those treated with LEF (0.34 ± 0.20 vs 1.12 ± 0.30, P < 0.05). CONCLUSIONS: Our algorithm combines structure and target pathways into one model that predicted that the combination of LEF and LIG can reduce joint inflammation and attenuate bone erosion in RA patients. To our knowledge, this study is the first to apply this paradigm to evaluate drug combination hypotheses.
RESUMEN
OBJECTIVE: To explore the correlations between symptom-based principal factors of rheumatoid arthritis (RA) and the effect of traditional Chinese medicine or Western medicine on RA after factor analysis of RA symptoms. METHODS: Four hundred and thirteen RA patients from 9 clinical centers were included in the clinical trial. They were randomly divided into Western medicine (WM) treated group with 204 cases and traditional Chinese medicine (CM) treated group with 209 cases. A complete physical examination and 18 common clinical manifestations were recorded before the randomization and after the treatment. The WM therapy included voltaren extended action tablet, methotrexate and sulfasalazine. The CM therapy included glucosidorum Tripterygll totorum tablet and Yishen Juanbi Tablet. The American College of Rheumatology 20 (ACR20) was used for efficacy evaluation. All data were analyzed on SAS 8.2 statistical package. Eighteen symptoms in the RA patients were analyzed by factor analysis and the relationships between the factors and effects were analyzed with Chi-Square test. RESULTS: Four principal factors were obtained from the analysis results of the 18 symptoms. The factors could represent the symptoms related to joints, cold-syndrome, deficiency syndrome and heat-syndrome in traditional Chinese medicine (TCM), respectively. The effect of WM therapy was better than CM therapy. After 12 weeks of treatment, the effect of CM on patients without deficiency-syndrome was better than the patients with deficiency-syndrome. After 24 weeks of treatment, WM therapy showed better effect on patients with cold syndrome than patients without cold syndrome. CONCLUSION: The results based on the factor analysis of RA symptoms are similar to the results of syndrome differentiation of TCM, and the factor-related different categories of symptoms are associated with the curative effect, thus further research on the symptoms is necessary.

BACKGROUND: Ginseng (Ginseng Radix et Rhizoma, Panax ginseng C.A. Meyer) is gaining more publicity in modern society due to its health benefit and huge value in market. In the practice of grading and pricing of ginseng, the age is one of the major factor influencing the price and grade of ginseng. Therefore, the age discrimination is an important task for the quality control of ginseng. However, the traditional morphological methods are too subjective to be reproductive in discrimination. PURPOSE: To establish a method that can discriminate the ginseng samples with different cultivation years. STUDY DESIGN: To analyze the correlation between chemical compositions and cultivation years of cultivated ginseng samples of different age and thus discover potential quality marker (Q-marker) for discriminating the age of cultivated ginseng. METHODS: In the present study, the ultra-high performance liquid chromatography coupled with the quadrupole-time of flight mass spectrometry (UHPLC-QTOF/MS) were utilized for the age discrimination and marker discovery. A statistical data processing procedure was established to screen markers and reduce the false positive rate. RESULTS: The results showed that the ginseng samples from 2- to 6-year-old could be well separated in the orthogonal projections on the latent structure - discrimination analysis (OPLS-DA) using the markers screened by the established statistical procedure, which could reduce approximately 20% of the insignificant markers and false positive discoveries. Ultimately, more than 50 compounds contributing to the age discrimination were identified including one new compound (malonylginsenoside). One negative marker (1038.4825@8.98) was discovered for the 2-year-old ginseng, and an equation was established to effectively predict the age of 3- to 6-year-old of ginseng. CONCLUSION: The constructed method can discriminate the ginseng samples with different cultivation years and is a complement to the traditional discrimination method of ginseng age.

OBJECTIVE: To analyse the cartilage erosion related blood biochemical and immune factors in rheumatoid arthritis (RA) and to explore the special influences of Chinese medicine (CM) and Western medicine (WM) on these factors. METHODS: Three hundred and ninety-seven patients, with confirmed diagnosis of active RA, were randomly assigned to the WM group (194 patients) and the CM group (203 patients). The WM applied covered non-steroid anti-inflammatory agents and slow acting medicine; and the CM given included basic remedy and syndrome differentiating medication. Related blood biochemical and immunological indexes were determined before and after treatment to screen out the cartilage erosion related factors and to compare the influence of CM and WM on them. RESULTS: Patients' peripheral red blood cell (RBC) and platelet (PLT) count were changed closely along with their degree of cartilage erosion. RBC count increased in the CM group and PLT count lowered in the WM group after treatment, all showed statistical significance; comparison of the two indexes between the two groups showed that statistical difference presented in RBC but not in PLT count. CONCLUSION: Both WM and CM can ameliorate the cartilage erosive factor in RA, but they are acting in different ways.

OBJECTIVE: To explore the correlationship between platelet count and efficacy of traditional Chinese medicine (TCM) or Western medicine (WM) in treating rheumatoid arthritis (RA) patients. METHODS: A total of 356 patients with confirmed diagnosis of active RA from 9 clinical centers were randomly assigned to the TCM group (184 cases) and the WM group (172 cases). The TCM group was treated with basic therapy (administration of glucosidorum tripterygll totorum and Yishen Juanbi Pill) and TCM syndrome differentiation dependent treatment, while the WM group was treated with non-steroidal anti-inflammatory drugs and slow-acting anti-rheumatic drugs. The therapeutic efficacy was assessed with ACR20, the joint damage degree of both hands was evaluated by X-ray. RESULTS: The platelet count was positively correlated to the X- ray grading of joint damage, namely, patients with a more severe joint damage often presented a higher platelet count. After treatment, in patients with joint damage of X-ray grade II or III and effectively treated with TCM, also in patients with joint damage of grade III and effectively treated with WM, the platelet count was lower than that in those treated ineffectively. CONCLUSION: Platelet count is closely correlated to the efficacy of drug therapy, therefore, it may be taken as an important index for judging the curative effect of therapeutic approach in treating RA patients.

OBJECTIVE: To analyze the indications of the therapies for rheumatoid arthritis (RA) with neural network model analysis. METHODS: Three hundred and ninety-seven patients were included in the clinical trial from 9 clinical centers. They were randomly divided into Western medicine (WM) treated group, 194 cases; and traditional Chinese herbal medicine (CM) treated group, 203 cases. A complete physical examination and 18 common clinical manifestations were prepared before the randomization and after the treatment. The WM therapy included voltaren extended action tablet, methotrexate and sulfasalazine. The CM therapy included Glucosidorum Tripterygii Totorum Tablet and syndrome differentiation treatment. The American College of Rheumatology 20 (ACR20) was taken as efficacy evaluation. All data were analyzed on SAS 8.2 statistical package. The relationships between each variable and efficacy were analyzed, and the variables with P<0.2 were included for the data mining analysis with neural network model. All data were classified into training set (75%) and verification set (25%) for further verification on the data-mining model. RESULTS: Eighteen variables in CM and 24 variables in WM were included in the data-mining model. In CM, morning stiffness, swollen joint number, peripheral immunoglobulin M (IgM) level, tenderness joint number, tenderness, rheumatoid factor (RF), C-reactive protein (CRP) and joint pain were positively related to the efficacy, and disease duration and more urination at night negatively related to the efficacy. In WM, erythrocyte sedimentation rate (ESR), weak waist, white fur in tongue, joint pain, joint stiffness and swollen joint were positively related to the efficacy, and yellow fur in tongue, red tongue, white blood negatively related to the efficacy. In the analysis with the neural network model in the patients of verification set, the predictive response rates of 20% patients would be 100% and 90% in the treatment with CM and WM, respectively. CONCLUSION: Neural network model analysis, based on the full clinical trial data with collection of both traditional Chinese medicine and modern medicine diagnostic information, shows a good predictive role for the information in the efficacy in rheumatoid arthritis.

@#Objective To explore ancient and modern medication laws of aromatic Chinese medicines in treating angina pectoris, and to provide new ideas for the clinical treatment. Methods With “angina pectoris” as the key word, ancient books prescriptions and Chinese patent medicines related to angina pectoris were collected from China National Knowledge Infrastructure (CNKI), Traditional Chinese Medicine Database System, Chinese Medicine Prescription Database, New National Proprietary Chinese Medicine (2nd edition), and Chinese Pharmacopoeia (2020 edition) from January 1, 2015 to December 31, 2021. Core high-frequency aromatic Chinese medicines were defined, and their potential medication rules were analyzed and summarized. Microsoft Access 2010 was used for data management. Data analysis software, including Excel and IBM SPSS Modeler 18.0 were used for drug association rule analysis, and Cytoscape 3.7.2 for visual display. Results There were 67 ancient books prescriptions and 258 Chinese patent medicines containing aromatic Chinese medicines treating angina pectoris collected from relevant databases. In ancient books prescriptions, there were nine aromatic Chinese medicines with the frequency ≥10, and the most commonly used medicine was Danggui (Angelicae Sinensis Radix), followed by Chenpi (Citri Reticulatae Pericarpium). There were 33 aromatic Chinese medicines with the frequency ≥10 in Chinese patent medicines, and the most commonly used medicine was Danshen (Salviae Miltiorrhizae Radix et Rhizoma), followed by Chuanxiong (Chuanxiong Rhizoma) and Sanqi (Notoginseng Radix et Rhizoma). In ancient books prescriptions, the medicines mainly belonged to intenal-warming medicines, Qi-regulating medicines, and blood circulation promoting and blood stasis removing medicines. There were eight medicine pairs with confidence equal to 100% in ancient books prescriptions, the most frequently used pairs were Chuanxiong (Chuanxiong Rhizoma) + Danggui (Angelicae Sinensis Radix), and Xiangfu (Cyperi Rhizoma) + Chenpi (Citri Reticulatae Pericarpium). In Chinese patent medicines, the aromatic Chinese medicine Chuanxiong (Chuanxiong Rhizoma) could be combined with many other Chinese medicines, among which the Confidence and Support of Chuanxiong (Chuanxiong Rhizoma) + Danshen (Salviae Miltiorrhizae Radix et Rhizoma) were at a high level. Conclusion Aromatic Chinese medicines for the treatment of angina pectoris of coronary heart disease are mainly warm, and the flavors are mainly pungent, sweet, and bitter. They mainly access to the liver, gallbladder, and pericardium meridians. The treatment of angina pectoris of coronary heart disease mainly focuses on warming heart pulse, and promoting blood circulation and removing blood stasis.
RESUMEN
OBJECTIVE: To explore the correlations between diagnostic information and therapeutic efficacy in rheumatoid arthritis (RA) with decision tree model analysis. METHODS: Three hundred and ninety seven patients came from 9 clinical centers were randomly divided into the Western medicine (WM) group (n=194) treated with non-steroidal anti-inflammatory drugs and slow-acting antirheumatic drug and the Chinese medicine (CM) group (n=203) with basic therapy and syndrome-differentiation dependant TCM treatment. TCM and WM diagnostic information were collected. The ACR 20 was used for efficacy evaluation and the information of patients before treatment was analyzed by SAS 8.2 statistical package. Through single-factor exploratory analysis, odds ratio of efficacy and variable was calculated taken P < 0.2 as the including criteria for data mining analysis with decision tree model. All data were classified into the training set (75%) and verifying set (25%) with efficacy as the variable for layering to make further verification of the data-mining analysis. RESULTS: Twenty variables were included in the CM group and 26 in the WM group in the data-mining model. In the former, 9 variables were positively correlated to the efficacy, including degree of arthralgia, tenderness and morning stiffness, number of swollen joint, and joint with tenderness, levels of IgM, rheumatoid factor (RF), C-reactive protein (CRP), and total assessment from doctor; and disease duration and degree of nocturnal polyuria were negatively correlated to that. While in the latter, 8 were positively correlated to the efficacy, including erythrocyte sedimentation rate (ESR), sour and weak waist and knees, white fur in tongue, joint ache and stiffness, swollen joint, and total assessment from doctor and patient, and red tongue with yellow fur and leucocyte count negatively correlated to it. Data mining with decision tree analysis revealed that different combinations of morning stiffness, slight red tongue, joint tenderness and nocturnal polyuria in the CM group, and those of white fur in tongue, CRP level, leucocyte count and morning stiffness in the WM group showed different efficacy, which were also verified in the randomly chosen verifying set. CONCLUSION: To analyze the correlations between diagnostic information and therapeutic efficacy with decision tree analysis is conformed to the theory of TCM in applying treatment according to syndrome differentiation individually, thus it would contribute to elevate the accuracy of therapy.

The treatment of traditional Chinese medicine (TCM) has been proved effective in clinical practice for thousands of years. To standardize the clinical protocols of TCM is absolutely necessary for enhancing the research quality of TCM and expanding the international influence of TCM. The standardization research on clinical protocols of TCM should be based on the basic theory of TCM and in the light of good clinical practice (GCP) principles. The clinical criteria for both diagnosis and efficacy evaluation of disease are also needed. To include all symptoms, tongue manifestations and pulse presentations into case report form, and to compare the differences in these clinical parameters between effective and non-effective cases by multivariate analysis may be helpful to find more specific indications for therapeutic protocol of TCM. Furthermore, It is suggested that two or more clinical trials on one therapeutic protocol are needed to identify its accurate indications.

AIM: To evaluate the correlation between CD4, CD8 cell infiltration in gastric mucosa, Helicobacter pylori (H pylori) infection and symptoms or the assemblage of symptoms in cases with chronic gastritis. METHODS: Biopsy samples at the gastric antrum were obtained from 62 patients with chronic gastritis. CD4 and CD8 cell infiltration was evaluated by immunohistochemical assays on frozen sections of the biopsy samples. Fifteen symptoms referring to digestion-related activity and non-digestion related activity were observed. The correlation between lymphocyte infiltration and each symptom or symptom assemblage was analyzed by logistic regression and K-mean cluster methods. RESULTS: CD4 cell infiltrations in gastric mucosa were much more in patients with H. pylori infection, while CD8 cell infiltrations were similar in patients with or without H. pylori infection. Logistic regression analysis showed that the symptoms including heavy feeling in head or body (t = 2.563), and thirst (t = 2.478) were significantly related with CD4 cell infiltration in gastric mucosa (P<0.05), and cool limbs with aversion to cold were related with CD8 cell infiltration (t = 2.872, P<0.05). Further analysis showed that non-digestive related symptom assemblage could increase the predicted percentage of CD4 and CD8 cell infiltration in gastric mucosa, including lower CD4 infiltration by 12.5%, higher CD8 infiltration by 33.3%, and also non-H. pylori infection by 23.6%. K-means cluster analysis of all symptoms and CD4 and CD8 cell infiltration in gastric mucosa showed a similar tendency to increase the predicted percentage of CD4, CD8 cell infiltration and H. pylori infection. CONCLUSION: Based on correlation between the gastric mucosa lymphocyte infiltration, H. pylori infection and clinical symptoms, symptoms or symptomatic assemblages play an important role in making further classification of chronic gastritis, which might help find a more specific therapy for chronic gastritis.
