RESUMEN
Background: Enteric glia are essential components of the enteric nervous system. Previously believed to have a passive structural function, mounting evidence now suggests that these cells are indispensable for maintaining gastrointestinal homeostasis and exert pivotal influences on both wellbeing and pathological conditions. This study aimed to investigate the global status, research hotspots, and future directions of enteric glia. Methods: The literature on enteric glia research was acquired from the Web of Science Core Collection. VOSviewer software (v1.6.19) was employed to visually represent co-operation networks among countries, institutions, and authors. The co-occurrence analysis of keywords and co-citation analysis of references were conducted using CiteSpace (v6.1.R6). Simultaneously, cluster analysis and burst detection of keywords and references were performed. Results: A total of 514 publications from 36 countries were reviewed. The United States was identified as the most influential country. The top-ranked institutions were University of Nantes and Michigan State University. Michel Neunlist was the most cited author. "Purinergic signaling" was the largest co-cited reference cluster, while "enteric glial cells (EGCs)" was the cluster with the highest number of co-occurring keywords. As the keyword with the highest burst strength, Crohns disease was a hot topic in the early research on enteric glia. The burst detection of keywords revealed that inflammation, intestinal motility, and gut microbiota may be the research frontiers. Conclusion: This study provides a comprehensive bibliometric analysis of enteric glia research. EGCs have emerged as a crucial link between neurons and immune cells, attracting significant research attention in neurogastroenterology. Their fundamental and translational studies on inflammation, intestinal motility, and gut microbiota may promote the treatment of some gastrointestinal and parenteral disorders.
RESUMEN
We performed this review to clarify which dietary and lifestyle factors are related to gastroesophageal reflux disease. Through a systematic search of the PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), and Chinese BioMedical Literature (CBM) databases, we identified articles with clear definitions of GERD, including nonerosive gastroesophageal reflux disease (NERD), reflux esophagitis (RE) and Barrett's esophagus (BE), that included dietary and lifestyle factors as independent factors affecting the onset of GERD (expressed as odds ratios (ORs) or relative risks (RRs) and 95% confidence intervals (CIs)). Due to heterogeneity among the studies, we used descriptive statistical analyses to analyze and synthesize each outcome based on the disease type. In total, 72 articles were included, conducted in ten Western countries (26 articles in total) and nine Eastern countries (46 articles in total). We categorized dietary factors into 20 items and lifestyle factors into 11 items. GERD is related to many irregular dietary and lifestyle habits (such as a habit of midnight snacking: OR=5.08, 95% CI 4.03-6.4; skipping breakfast: OR=2.7, 95% CI 2.17-3.35; eating quickly: OR=4.06, 95% CI 3.11-5.29; eating very hot foods: OR=1.81, 95% CI 1.37-2.4; and eating beyond fullness: OR=2.85, 95% CI 2.18-3.73). Vegetarian diets (consumption of nonvegetarian food (no/yes); OR=0.34, 95% CI 0.211-0.545) and no intake of meat (OR=0.841, 95% CI 0.715-0.990) were negatively related to GERD, while meat (daily meat, fish, and egg intake: OR=1.088, 95% CI 1.042-1.135) and fat (high-fat diet: OR=7.568, 95% CI 4.557-8.908) consumption were positively related to GERD. An interval of less than three hours between dinner and bedtime (OR=7.45, 95% CI 3.38-16.4) was positively related to GERD, and proper physical exercise (physical exercise >30 minutes (>3 times/week): OR=0.7, 95% CI 0.6-0.9) was negatively correlated with GERD. Smoking (OR=1.19, 95% CI 1.12-1.264), alcohol consumption (OR=1.278, 95% CI 1.207-1.353) and mental state (poor mental state: OR=1.278, 95% CI 1.207-1.353) were positively correlated with GERD. RE (vitamin C: OR=0.46, 95% CI=0.24-0.90) and BE (vitamin C: OR=0.44,95% CI 0.2-0.98; vitamin E: OR=0.46, 95% CI 0.26-0.83) were generally negatively correlated with antioxidant intake. In conclusion, many dietary and lifestyle factors affect the onset of GERD, and these factors differ among regions and disease types. These findings need to be further confirmed in subsequent studies.
RESUMEN
BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most universal malignant liver tumors worldwide. However, there were no systematic studies to establish glycolysisrelated gene pairs (GRGPs) signatures for the patients with HCC. Therefore, the study aimed to establish novel GRGPs signatures to better predict the prognosis of HCC. METHODS: Based on the data from Gene Expression Omnibus, The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium databases, glycolysis-related mRNAs were used to construct GRGPs. Cox regression was applied to establish a seventeen GRGPs signature in TCGA dataset, which was verified in two validation (European and American, and Asian) datasets. RESULTS: Seventeen prognostic GRGPs (HMMR_PFKFB1, CHST1_GYS2, MERTK_GYS2, GPC1_GYS2, LDHA_GOT2, IDUA_GNPDA1, IDUA_ME2, IDUA_G6PD, IDUA_GPC1, MPI_GPC1, SDC2_LDHA, PRPS1_PLOD2, GALK1_IER3, MET_PLOD2, GUSB_IGFBP3, IL13RA1_IGFBP3 and CYB5A_IGFBP3) were identified to be significantly progressive factors for the patients with HCC in the TCGA dataset, which constituted a GRGPs signature. The patients with HCC were classified into low-risk group and high-risk group based on the GRGPs signature. The GRGPs signature was a significantly independent prognostic indicator for the patients with HCC in TCGA (log-rank P = 2.898e-14). Consistent with the TCGA dataset, the patients in low-risk group had a longer OS in two validation datasets (European and American: P = 1.143e-02, and Asian: P = 6.342e-08). Additionally, the GRGPs signature was also validated as a significantly independent prognostic indicator in two validation datasets. CONCLUSION: The seventeen GRGPs and their signature might be molecular biomarkers and therapeutic targets for the patients with HCC.
RESUMEN
OBJECTIVE: Chinese Medicinal Properties (CMP) play a vital role in theoretical research and clinical practice. However, the traditional CMP system is subjective, qualitative, fixed, inconsistent, and obscured. Nowadays, quantifying CMP research achieved a notable progress. This study aims to review and reflect the relevance between qualitative CMP and quantitative material components. METHODS: A raw literature search was performed firstly in CNKI and Pubmed database to get a rough idea on the general advances in measuring CMP. Then, a strict literature search and data extraction from two dependent research studies were performed to analyze the relevance and discrimination between CMP and material components. RESULTS: The quantitative CMP research mainly focused on the microelements and chemical compositions. The largest microelements research listed 747 Chinese Materia Medica (CMM) (6780 flavors) and 120,000 element data. The measurement of chemical composition of CMM has risen rapidly in the 1990s and continues till the present. Thirty-seven articles were finally identified for the relevance analysis of CMP and material components. Of these, 18 and 19 articles correspondingly focused on the chemical compositions and microelements, and 26 and 11 articles correspondingly focused on their correlation and discrimination relationship. The most commonly used method for correlation analysis is intuitive analysis. The support vector machine maybe highly efficient and would act as the preferred method in discriminant analysis. Twelve (67%) and 5 (26%) articles' data came from the literature search in chemical compositions and microelement research studies. Four studies indicated that the research objects are the basic substances and material basis of CMP, 15 articles claimed that the chemical compositions were significantly related to CMP, 12 research studies concluded that the regularity and causality were identified between the research objects and CMP, and 9 research studies successfully established discriminant models for CMP basing on the detected substances. CONCLUSIONS: The relevance research between qualitative CMP and quantitative material components achieved a positive progress, though it is weak and defective. Standardizing the qualitative CMP system, establishing series comprehensive databases for the material components, innovating statistical and data mining methods, and integrating doctors' experiences are important and feasible for future research.
RESUMEN
BACKGROUND: Serum exosomal microRNAs (miRNAs) have been suggested as novel biomarkers for various diseases, especially gastric cancer (GC). But circulating biomarkers for Chronic atrophic gastritis (CAG) which is defined as precancrerous lesions of GC remain largely elusive. To investigate serum exosomal miRNAs that are differently expressed in CAG patients and Chronic nonatrophic gastritis (CNAG) may be helpful for its diagnosis and therapy. METHODS: Patients were recruited according to the diagnosis and exclusioncriteria. RNA was extracted from serum exosomes of 30 CAG and 30 CNAG patients. The miRNA expression profiles were analyzed by next generation sequencing and were validated by qRT-PCR. Receiver operating characteristic (ROC) analysis has been used to evaluate the diagnostic value. RESULTS: 30 CAG patients and 30 CNAG patients were recruited in our study. sRNA-seq results showed that hsa-miR-3591-3p, - 122-3p, and - 122-5p of the top 10 miRNAs (hsa-miR-148a-3p, - 122-3p, - 486-3p, -451a, - 122-5p, - 3591-3p, - 486-5p, -151a-3p, -92a-3p, -320a) were significantly upregulated in exosomes from CAG patients versus those from CNAG patients, but hsa-miR-451a, -151a-3p, and -92a-3p were significantly downregulated. Furthermore, qRT-PCR analysis confirmed that hsa-miR-122-5p and hsa-miR-122-3p were significantly upregulated in CAG samples, but hsa-miR-122-3p hadnot a steable expression. ROC curves showed that the AUC for hsa-miR-122-5p was 0.67 (95% CI 0.52-0.82, SE 62%, SP 86%). A sum of the four miRNAs (panel 1, hsa-miR-122-5p, -451a, -151a-3p, and -92a-3p) did not significantly improve the diagnostic potential (AUC 0.63, 95% CI 0.47 to 0.78). Correlation analysis showed that the expression of hsa-miR-122-5p differed significantly between patients based on atrophic (Moderate atrophic vs. Absent, P value was 0.036.) and IM (compare moderate-severe, absent and mild P values were 0.001 and 0.014, respectively). However, there were no differences between groups based on age, gender, dysplasia, or chronic or active inflammation. CONCLUSION: These results suggested that hsa-miR-122-5p in serum exosomes might serve as a potential biomarker for CAG diagnosis.

Introduction: NRAS gene is associated with malignant proliferation and metastasis of colorectal cancer (CRC). But its prognostic value on CRC is still unknown. The objective of this study is to perform a meta-analysis to obtain its prognostic value on survival of CRC patients. Methods: The systematic review and meta-analysis was designed, undertaken and reported using items from the PRISMA statement. Relevant articles were identified through PubMed (containing Medline), Embase, Web of Science databases and Google scholar search engines from their inception up to October 3, 2016. The articles about NRAS on prognosis of CRC patients were enrolled. The association between NRAS and CRC survival time (including overall survival [OS], progression-free survival [PFS], and disease-free survival [DFS]) was evaluated using hazard ratio (HR) with its corresponding 95% confidence interval (CI). Results: A total of fifteen articles were included. High-expression of NRAS was significantly associated with poor OS (HR: 1.36, 95% CI: 1.151.61), and poor PFS (HR: 1.75, 95% CI: 1.042.94). The combined HR of NRAS on DFS was 0.87 (95% CI: 0.372.03). Subgroup analysis showed that NRAS was significantly associated with poor OS for patients from Western countries (HR: 1.38, 95% CI: 1.091.73), but not for those from Asian countries. Conclusions: This meta-analysis demonstrate that NRAS gene could predict the poor prognosis for the CRC patients. More large-sample cohort studies are needed to further confirm this conclusion.

The aim of this study was to develop and validate the large intestine dampness-heat syndrome questionnaire (LIDHSQ) for patients with ulcerative colitis (UC). The domains and items of the LIDHSQ were developed according to standard procedures, namely, construct definition, item generation, language testing, content validity, pilot study, and validation study. At first, a total of 20 items in 3 domains were generated based on literature review and expert consultation. After the item selection, the LIDHSQ contains 11 items in three domains: disease-related domain (diarrhoea, abdominal pain, bloody purulent stool, and mucus stool), heat domain (fever, dry mouth, red tongue, yellow fur, and anal burning), and dampness domain (greasy fur and defecation disorder). The Cronbach's alphas of all domains were greater than 0.6. All of the intraclass correlation coefficients were greater than 0.8. The LIDHSQ and domain scores of the patients with LIDHS were higher than those of the patients with other syndromes (P < 0.001). The area under the receiver operating characteristic curve of the LIDHSQ was 0.900, with a 95% confidence interval of 0.872-0.928. When the cut-off value of the LIDHSQ was ≥ 7, the sensitivity and specificity were 0.867 and 0.854, respectively. The LIDHSQ is valid and reliable for measuring LIDHS in UC patients with good diagnostic efficacy. We recommend the use of the LIDHSQ in Chinese UC patients.
RESUMEN
The Rome Foundation released the Rome â £ for functional gastrointestinal diseases (FGIDs) in 2016, which fully presented the latest advances and views on the disease origin, definition, diagnosis, classification, pathology, mechanism, clinical features, influential factors, interventions, clinical evaluation, clinical research design and so on, showing high positive effects on global researches. Traditional Chinese medicines (TCM) have cognitive advantages and well-recognized and-demonstrated efficacy in the prevention and treatment for FGIDs. However, the monotonous presentation ways and weak interpretation on clinical evaluation have also hindered the inherent advantages explanation, characteristics quantization, evidence and communication accumulation. This study first analyzed the background and key points on clinical evaluation of Rome â £ and corresponding inspirations, believed that its concept and viewpoints were assimilated with systematic medicine, and emphasized the important influence of subjective factors such as mental psychology and social culture on the disease and its importance in clinical evaluation. Its views on several aspects such as the theoretical model, internal and external causes, and transfer process were highly consistent with TCM. Therefore, TCM researchers should devote more dedication and courage on the innovation and collaboration with global researches to advance related studies. Then, based on 59 TCM clinical researches for FGIDs funded by national projects upon searching in CNKI with strict search strategy, the clinical evaluation methods and indexes and their correlations were summarized and analyzed, and it was found that more attention was paid to the disease symptoms and impact, symptom/syndrome score, patient report outcome, et al. However, many limitations were also founded, such as disordered relationships among different indexes, ambiguous explanation of research results, and extremely few domestic evaluation instruments in Chinese culture. Therefore, it is suggested that future research should regress and highlight the subjective features of patients and diseases, standardize the elemental structure and management mode of clinical evaluation, enhance the values and status of reported outcomes. It is highly recommended that the domestic disease-specific instruments developed in Chinese culture should be adopted as primary outcome for clinical evaluation, assisted with symptoms/signs assessment tools and doctors reporting outcome scale, et al. The common used TCM syndrome scores in current researches are not recommended as the primary outcome. However, there are some limitations in the above suggestions. We hope that more relevant researches will explore and establish a unified outcome assessment system for FGIDs and improve the quality of TCM clinical research.

To analyze and summarize Professor LIU Feng-bin's clinical experience and academic thoughts on gastroesophageal reflux disease (GERD), the study group adopted the retrospective study for case series and expert interview, extracted the retrospective data, including the herbs, diseases, syndrome type, medical expense and quantity of herbs of GERD patients attended the First Affiliated Hospital of Guangzhou University of Chinese Medicine. Statistical description and binary Logistic regression were used for the identification and modification of syndrome type and initial core herbs. After expert interviews were performed for the syndrome type and herbs, the final scheme were formed. A total of 112 GERD patients agesï¼48.97±13.13ï¼y; male: 35 (31.3%), female: 77(68.7%) were enrolled. The numbers of patients with liver and stomach incoordination syndrome, heat stagnation of liver and stomach syndrome, syndrome of dual deficiency of Qi and Yin, syndrome of spleen deficiency and dampness-heat, spleen-stomach disharmony syndrome were 40, 26, 19, 17 and 10, respectively. The patients used totally 80 herbs, and 26 of them had significant differences among different syndrome groups. According to the logistic regression analysis on the 23 herbs used by 112 patients, the herbs scheme was modified for the second time. After the expert interviews and modification, the final consensus was reached. The main causes for GERD were dietary irregularities, moodiness, and weak constitution. The basic mechanism of GERD was spleen deficiency with Qi adverseness. The spleen-stomach disharmony syndrome was deleted by expert interviews. The 10 core herbs for GERD treatment were Taizishen(Pseudostellariae Radix), Fuling(Poria), Baizhu(Atractylodismacrocephalae Rhizoma), Gancao(Glycyrrhizae Radix Et Rhizoma), Zhebeimu(Fritillariae Thunbergii Bulbus), Haipiaoxiao(Sepiae Endoconcha), Zhiqiao(Aurantii Fructus), Chenxiang(Alosewood), Pugongying(Taraxaci Herba), Zhizitan(Cape Jasmine Fruit). The modification and psychological and diet interventions were also identified. This study summarized Professor LIU Feng-bin's clinical experience and academic thoughts of chronic atrophic gastritis based on data mining of case series and expert interviews. The quality of methodologies and report were both well. The results provide a foundation and ideas for further study on the complex intervention for GERD, and can be directly applied in clinical practice.

BACKGROUND AND AIM: The Chinese version quality of life questionnaire for functional digestive disorders (Chin-FDDQL) is a useful health assessment instrument for functional dyspepsia. This study aims to identify its score interpretation for clinical practice. METHODS: Data of Chin-FDDQL from the functional dyspepsia patients (≥ 18 years) between November 2009 and April 2013 were enrolled in the 1st and 14th day. After baseline and responsiveness analysis, the single score interpretation and percentile ranks were established. The statistically reliable change was defined with effect size, standardized response mean, minimal detectable change, and others. Then the receiver operating characteristic curve analysis for health improvement was performed to define the clinically important change. RESULTS: Two hundred two functional dyspepsia patients, 150 healthy participants, and 25 missing data were enrolled for analysis. Compared with the intake patients, the discharged and healthy persons have significant better health status in all domains (P < 0.001, expect discomfort in discharged people, P = 0.142), totally contrast to missing data. The reliability for single total intake and discharge were both ± 1. Based on score distribution, the 25th, 50th, and 75th percentile ranks were 49, 58, and 66 for intake scores and 59, 65, and 72 for discharge scores, respectively. The minimal detectable change and Reliable Change Index were 6 and 11 for total score. Receiver operating characteristic analyses supported that total score changes 4 or more represented minimal clinically important improvement. CONCLUSIONS: The score interpretation system of the Chin-FDDQL could assist clinician's decision making during the therapy practice.

BACKGROUND: This review aims to critically appraise and compare the measurement properties of inflammatory bowel disease (IBD)-specific health-related quality of life instruments. METHODS: Medline, EMBASE and ISI Web of Knowledge were searched from their inception to May 2016. IBD-specific instruments for patients with Crohn's disease, ulcerative colitis or IBD were enrolled. The basic characteristics and domains of the instruments were collected. The methodological quality of measurement properties and measurement properties of the instruments were assessed. RESULTS: Fifteen IBD-specific instruments were included, which included twelve instruments for adult IBD patients and three for paediatric IBD patients. All of the instruments were developed in North American and European countries. The following common domains were identified: IBD-related symptoms, physical, emotional and social domain. The methodological quality was satisfactory for content validity; fair in internal consistency, reliability, structural validity, hypotheses testing and criterion validity; and poor in measurement error, cross-cultural validity and responsiveness. For adult IBD patients, the IBDQ-32 and its short version (SIBDQ) had good measurement properties and were the most widely used worldwide. For paediatric IBD patients, the IMPACT-III had good measurement properties and had more translated versions. CONCLUSIONS: Most methodological quality should be promoted, especially measurement error, cross-cultural validity and responsiveness. The IBDQ-32 was the most widely used instrument with good reliability and validity, followed by the SIBDQ and IMPACT-III. Further validation studies are necessary to support the use of other instruments.

Currently, there are increasing debates on the necessity of health instruments in Chinese medicine (CM) emerging in China. This study aims to reevaluate its status and values. Analyzing the causes, limits, advantages, and properties characters of health instruments in CM, it is found that weak fundamental research, incomplete self-awareness, and complicated social factors are the primary causes of debates. A comprehensive analysis showed health instruments in CM have health evaluation benefits to people from a dominant Chinese culture, meet the requirements of cultural background, and bring long-term value to Chinese instrument researches. However, its values and status should be treated differently depending on various subtypes. Although little theoretical and practical evidences proved that patients-reported health instruments in CM should be proposed independently, the doctors- and nurses-reported questionnaires are necessary. With this in mind, the study group proposes the 'Chinese cultural instruments (CCIs)' and 'health-related CCIs'. The latter one aims to evaluate the health status of people in a dominant Chinese culture. The CCIs theory represents Chinese instrument researches on a larger regional and higher level, and resolves the debates on instruments between CM and Western medicine in China. Health instruments in CM bring more scientific and social benefits for Chinese instrument researches. However, it does not include cultural demands, and lacks scientific significance. CCIs have all its virtues, and add solutions to the latter's theory bottleneck and scientific debates, thus bringing increased benefits to clinical assessment in complementary and alternative medicine researches.

In order to clarify the traditional Chinese medicine(TCM) syndrome distribution and pathogenesis of irritable bowel syndrome(IBS), the patients in the first affiliated hospital of Guangzhou university of Chinese medicine were enrolled for the cross-sectional study. The data of 12 sociological variables, 13 risk factors, 84 symptoms and signs variables(in 9 aspects), and 19 neuroendocrine indices were extracted for group-between analysis with one-way ANOVA, chi-square test and nonparametric test, and the relationship analysis between clinical symptoms and diseases sub-types was done with binary Logistic regression. In addition, the patterns of TCM syndromes were divided by several syndrome factors to analyze the difference in neuroendocrine indices between various patterns and syndrome factors. A total of 383 IBS patients were enrolled, including 353(92.2%) cases of diarrhea, 14(3.7%) cases of constipation and 16(4.1%) cases of mixed types. In IBS-diarrhea patients, there were 291(76.0%), 18(4.7%), 48(12.5%) and 26(6.8%)cases of syndrome of liver depression and spleen deficiency (sLDSD), syndrome of liver depression and qi stagnation (sLDQS), syndrome of dampness-heat in the spleen and stomach (sDHSS), and syndrome of spleen deficiency with dampness encumbrance (sSDDE) respectively. There was significant differences in blood groups between IBS-diarrhea patients, IBS-constipation patients and IBS-mixed types patients; their disease classification was significantly correlated with the allergies, drinking, irregular meals habits, no or less vacations, and other causes of morbidity (P<0.05, f<0.3). A total of 15 symptoms and signs variables (e.g., chills, facial abnormalities, epigastric fullness, etc.) had significant differences between different groups (P<0.05), and 5, 8, 5 variables were respective independent factors for IBS-diarrhea, constipation and mixed type. There was no significant difference in neuroendocrine indices between various groups. The sLDSD, sLDQS, sDHSS, sSDDE patients had significant differences in genders, living conditions and occupations, and the TCM syndrome type was significantly correlated with the drinking, smoking, no or less breakfast, less than 8 sleeping hours(P<0.05, f<0.3). Meanwhile, a total of 14 symptoms and signs variables (e.g., dysphoria heat, fatigue, stretching, etc.) had significant differences between various groups(P<0.05) and 3, 4, 6, 3 variables were respective independent factors for sLDSD, sLDQS, sDHSS, and sSDDE. There were significant differences in acetylcholine(Ach) and angiotensin â ¡(AT-â ¡) between the sLDSD group and sSDDE group. There were significant difference in Ach, AT-â ¡, adrenotrophin(ACTH) and estradiol (E2) in comparison between several pattern factors. This study preliminary identified the sociological characters, risk factors, syndromes distribution, diseases and subgroup mechanisms of this disease. More samples and multi-centers are required for future study to improve the scientificity and representativeness.

To summarize Professor LIU Feng-bin's clinical experience and theoretical thoughts on chronic atrophic gastritis (CAG), the study group designed a retrospective study on his case series and expert interview. First of all, the data of CAG patients treated in the First Affiliated Hospital of Guangzhou University of Chinese Medicine between 2009 and 2013, e. g. herbs, diseases, syndrome type, prescription amount and number of herbs, was collected and processed. The statistical description and binary logistic regression were used to determined the syndrome type, initial basic remedy and modification. During the statistics, a complete and sub-group analysis was performed simultaneously. After the expert interview, the syndrome type and medication were finalized. As a result, a total of 228 CAG patients aged at (50.30 ± 10.18) were collected, including 151 males (66.23%). Of them, the TCM diagnosis and syndrome type were extracted from the information of 157 patients, including 115 cases with gastric stuffiness, 23 cases with gastric pain, 19 missing cases, 2 cases with spleen-stomach weakness syndrome, 57 cases with spleen deficiency and dampness-heat syndrome, 18 cases with spleen-stomach disharmony syndrome, 23 cases with syndrome of liver depression syndrome, 21 cases with liver qi invading stomach syndrome and 26 qi and yin deficiency syndrome, respectively. All of the 228 patients used totally 104 herbs, while the subgroups with 157 patients used 94 herbs. The most frequently used 15 herbs used in each groups were analyzed to determine the initial basic remedy and modification. Subsequently, based on the information of the sub-groups with 157 patients, with the syndrome type as the dependent variable, the logistic regression analysis was made on the most frequently used 32 herbs, in order to determined the modification in herbs for different syndrome types. After experts reviewed and modified, they believed the main causes of CAG were dietary irregularities, moodiness and weak constitution; the pathogenesis of CAG was spleen deficiency with qi stagnation, heat depression and blood stasis in the stomach meridian. The above six syndrome types and 12 herbs were determined, including Pseudostellariae Radix, Poria, Atractylodismacrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Fritillariae Thunbergii Bulbus, Sepiae Endoconcha, Arecae Pericarpium, Aurantii Fructus, Perillae Caulis, Herba Hedyotis Diffusae, Scutellariae Barbatae Herba, Curcumae Rhizoma. This study summarized Professor LIU Feng-bin's clinical experience and theoretical thoughts of chronic atrophic gastritis based on clinical practice data and expert interview, with a rigorous design and good scientificity and practicability.

OBJECTIVE: To develop and evaluate the short version of patient reported outcomes (PROs) questionnaire for gastric stuffiness (Wei Pi) patients with modern test theory and technologies, hoping to provide testing tools for related clinical practice and scientific researches with higher quality and less administrative and response burdens. METHODS: Using descriptive study design, clinical data were collected with sociological questionnaire and previous developed full items version of PROs instrument for gastric stuffiness (Wei Pi) patients via field and online surveys between Sep 2011 and Mar 2012. The statistical analysis group identified the termination parameters firstly, and then selected items with discrimination, fitting residual, item information curve (IIC) , item characteristic curve (ICC), and the rank of computerized adaptive testing (CAT) select proportion, etc. After assumption evaluation of item response theory (IRT), IIC, ICC, difficulty coefficient distribution, items-response relation and thresholds, etc. were used for psychometric evaluation of instrument. RESULTS: A total of 331 patients [Ages: 31.99 +/- 10.29 yrs; Male: 186 (56.3%)] were enrolled in statistical analysis. The test termination criterion was Max SE = 0.2 or Max items number =16. After items selection, a 15-item short version of instrument, which contains symptoms facet (8 items) and impact facet (7 items) was generated. With good unidimensionality, local independence, and monotonicity, the IC and ICC in IRT analysis showed good working capability of the questionnaire. The difficulty coefficient distribution and items-response relation were also rational, as well as response thresholds. CONCLUSIONS: The short version of PROs instrument for adult gastric stuffiness (Wei Pi) patients was successfully developed and assessed. The instrument with good methodological and reporting quality could be used in clinical and scientific evaluating their symptoms and impact.

Nowadays, the simple combination of Western medicine (WM) and complementary and alternative medicine (CAM) cannot resolve all the health problems and various requirements. This article proposed the general integral medicine (GIM) theoretical model, which declares the disease causes analysis, clinical intervention and outcomes assessment should be recognized, managed and evaluated both from physiological, psychological, and spiritual status, and all the four dimensions: orthodox medicine (WM, Chinese medicine, etc.), individual inherent characteristics (emotion, attitude, psychology, etc.), cultural influences (doctors, caregivers, groups care, etc.), and natural environment and social systems (economic status, social security system, environmental pollution, etc). As for health outcomes assessment, a more comprehensive system including biological, doctors, patients, health intimate, social and environmental evaluations were required. The GIM model has individualized, dynamic, standardized, objective, systematic inherent characteristics, and opening and compatible external characteristics. It aims to provide the new theoretical guidance and strategic development direction for complex health interventions, and solve various medical related psychological and social problems.

OBJECTIVE: To evaluate the application of health assessment instruments in Chinese medicine. METHODS: According to a pre-defined search strategy, a comprehensive literature search for all articles published in China National Knowledge Infrastructure databases was conducted. The resulting articles that met the defined inclusion and exclusion criteria were used for analysis. RESULTS: A total of 97 instruments for health outcome assessment in Chinese medicine have been used in fundamental and theoretical research, and 14 of these were also used in 29 clinical trials that were randomized controlled trials, or descriptive or cross-sectional studies. In 2 152 Chinese medicine-based studies that used instruments in their methodology, more than 150 questionnaires were identified. Among the identified questionnaires, 51 were used in more than 10 articles (0.5%). Most of these instruments were developed in Western countries and few studies (4%) used the instrument as the primary evidence for their conclusions. CONCLUSION: Usage of instruments for health outcome assessment in Chinese medicine is increasing rapidly; however, current limitations include selection rationale, result interpretation and standardization, which must be addressed accordingly.

OBJECTIVE: To evaluate the development of health outcomes assessment instruments in Chinese medicine. METHODS: A comprehensive literature search for all published articles in China National Knowledge Infrastructure Database, Chongqing VIP Database and WANFANG Data was conducted. The studies that met the inclusion and exclusion criteria were used to extract information according to a predesigned assessment instrument. RESULTS: A total of 97 instruments for health outcome assessment in Chinese medicine were identified. Of these questionnaires, 7 were generic, 12 were condition-specific and 78 were disease-specific. All instruments were suitable for adults, children, and both men and women. These instruments aimed to evaluate the health-related quality of life, signs and symptoms as well as patient satisfaction and doctor-reported outcome. However, the descriptions were poorly constructed for some of the most basic parameters, such as the domains and items, administrative mode, response options, memory recall periods, burden evaluation, format, copyright, content validity, and other properties. CONCLUSION: The instrument development for health outcomes assessment in Chinese medicine is increasing rapidly; however, there are many limitations in current methodologies and standards, and further studies are needed.

OBJECTIVE: The reporting of patient-reported outcomes (PRO) instrument development is vital for both researchers and clinicians to determine its validity, thus, we propose the Preferred Reporting Items for PRO Instrument Development (PRIPROID) to improve the quality of reports. METHODS: Abiding by the guidance published by the Enhancing the QUAlity and Transparency Of health Research (EQUATOR) Network, we had performed 6 steps for items development: identified the need for a guideline, performed a literature review, obtained funding for the guideline initiative, identified participants, conducted a Delphi exercise and generated a list of PRIPROID items for consideration at the face-to-face meeting. RESULTS: Twenty three items subheadings under 7 topics were included: title and structured abstract, rationale, objectives, intention, eligibility criteria, conceptual framework, items generation, response options, scoring, times, administrative modes, burden assessment, properties assessment, statistical methods, participants, main results, and additional analysis, summary of evidence, limitations, clinical attentions, and conclusions, item pools or final form, and funding. CONCLUSIONS: The PRIPROID contains many elements of the PRO research, and this assists researchers to report their results more accurately and to a certain degree use this instrument to evaluate the quality of the research methods.

OBJECTIVE: To identify prognostic factors in middle-aged and elderly patients with community-acquired pneumonia (CAP) who underwent integrated interventions involving traditional Chinese medicine (TCM) and modern medicine. METHODS: Patients aged > or =45 years and diagnosed with CAP were divided into a middle-aged cohort (45-59 years) and an elderly cohort (> or =60 years), and clinical data comprising 75 predictor variables in seven classes were collected. After replacing missing data, calibrating multicenter differences and classifYing quantitative data, univariate and multivariate analysis were performed. RESULTS: On multivariate analysis, eight independent risk factors--respiration rate, C reactive protein (CRP), cost of hospitalization, anemia, gasping, confusion, moist rales and pneumonia severity index (PSI)--were correlated with the outcome "not cured" in the elderly cohort. Nine factors--neutrophil percentage (Neu%), blood urea nitrogen (BUN), time to clinical stability, appetite, anemia, confusion, being retired or unemployed, Gram-negative bacterial infection and educational level were correlated with not cured in the middle-aged cohort. CONCLUSION: Independent predictive risk factors correlated with adverse outcomes in elderly patients were higher respiration rate, CRP > or = four times the mean or median for the patient's center, cost of hospitalization >11,323 RMB and PSI >11, plus anemia, gasping, confusion and moist rales; those in middle-aged patients were higher Neu%, BUN > or = mean or median, loss of appetite, anemia, confusion, being retired or unemployed and lower educational level. Gram-negative bacterial infection and time to clinical stability >9 days were protective factors.
