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. © 2010 The Author(s).

Background: Achieving good glycemic control improves clinical outcomes among patients with type 2 diabetes (T2D). This study aimed to explore non-pharmaceutical factors for poor glycemic control in Chinese women with T2D who used antidiabetic drug(s). Methods: A cross-sectional survey was conducted in March to June 2011 in 77 top tertiary hospitals in Beijing, Shanghai, Tianjin, and Guangzhou, People’s Republic of China (the coverage rates of the 3A hospitals: 74.4%, 76%, 55%, and 29.3%, respectively). Of 29,502 patients with T2D who used oral antidiabetic drugs (OADs) alone or combined with insulin, 13,970 were women and used in the analysis. Logistic regression analysis was used to obtain odds ratios (ORs) and 95% confidence intervals (CIs) of factors for hyperglycemia defined as HbA1c (glycated hemoglobin) ≥77 mmol/mol (7.0%). Results: The mean age was 60.3 (standard deviation 11.0) years, with a median of 4 (interquartile range 2–9) years of duration of diabetes, and 65.1% had hyperglycemia. In multivariable analysis, body height of ≥164 cm (OR 1.26, 95% CI 1.15–1.37) and obesity (OR 1.16, 95% CI 1.04–1.31) was associated with increased risk of hyperglycemia, while self-monitoring blood glucose (SMBG) decreased the risk of hyperglycemia (OR 0.78, 95% CI 0.73–0.84). Duration of diabetes ≥3 years (≥3 to ≥6 years, OR 1.46, 95% CI 1.32–1.62; ≥6 to ≥10 years, OR 1.65, 95% CI 1.44–1.89), especially ≥10 years (OR 1.95, 95% CI 1.73–2.19), was associated with higher risks of hyperglycemia. Conclusion: Body height ≥164 cm, obesity, and duration of diabetes ≥3 years increased while SMBG decreased risk of hyperglycemia in Chinese women with OAD-treated T2D. © 2014 Lu et al.

Mutations of integrin-interacting protein Kindlin-1 cause Kindler syndrome and deregulation of Kindlin-1 is implicated in human cancers. The Kindlin-1-related diseases are confined in limited tissue types. However, Kindlin-1 tissue distribution and the dogma that governs Kindlin-1 expression in normal human body are elusive. This study examined Kindlin-1 expression in normal human adult organs, human and mouse embryonic organs by immunohistochemical analyses. We identified a general principle that the level of Kindlin-1 expression in tissues is tightly correlated with the corresponding germ layers from which these tissues originate. We compared the expression of Kindlin-1 with Kindlin-2 and found that Kindlin-1 is highly expressed in epithelial tissues derived from ectoderm and endoderm, whereas Kindlin-2 is mainly expressed in mesoderm-derived tissues. Likewise, Kindlin-1 was also found highly expressed in endoderm/ectoderm-derived tissues in human and mouse embryos. Our findings indicate that Kindlin-1 may play an importance role in the development of endoderm/ectoderm related tissues. © 2015, The Author(s).

In our precious study, the correlation between cold and hot patterns in traditional Chinese medicine (TCM) and gene expression profiles in rheumatoid arthritis (RA) has been explored. Based on TCM theory, deficiency pattern is another key pattern diagnosis among RA patients, which leads to a specific treatment principle in clinical management. Therefore, a further analysis was performed aiming at exploring the characteristic gene expression profile of deficiency pattern and its correlation with cold and hot patterns in RA patients by bioinformatics analysis approach based on gene expression profiles data detected with microarray technology. The TCM deficiency pattern-related genes network comprises 7 significantly, highly connected regions which are mainly involved in protein transcription processes, protein ubiquitination, toll-like receptor activated NF-B regulated gene transcription and apoptosis, RNA clipping, NF-B signal, nucleotide metabolism-related apoptosis, and immune response processes. Toll-like receptor activated NF-B regulated gene transcription and apoptosis pathways are potential specific pathways related to TCM deficiency patterns in RA patients; TCM deficiency pattern is probably related to immune response. Network analysis can be used as a powerful tool for detecting the characteristic mechanism related to specific TCM pattern and the correlations between different patterns. © 2013 Minzhi Wang et al.

Objective: In China, high-fat diets and excessive energy intake have led to an increasing prevalence of obesity which was previously uncommon. The current study examined the effects of meal replacement (MR) on weight control in overweight or obese Chinese individuals with hyperlipidemia. Methods: Patients, 18–65 years, with body mass index 25–35 kg/m2 and triglycerides >1.7 and <5.4 mmol/L were enrolled. Major exclusion criteria were: type II diabetes, fasting glucose ≥7.0 mmol/L, glycosylated hemoglobin ≥6.5%; weight loss surgery or use of weight loss drugs; weight fluctuations >2%; use of cholesterol-lowering drugs. Eligible patients were randomized 1:1 to a high-protein (HP) diet (2.2 g protein/kg/day) or a standard-protein (SP) diet (1.1 g protein/kg/ day) provided twice daily for 3 months. Assessments included body weight, waist-hip ratio, body fat percentage, blood lipids, blood glucose, insulin, liver and kidney function. Results: Although mean weight loss and percent BMI reduction were greater with HP than SP at 12 weeks, the differences were not significant. There was, however, a significantly greater decrease in waist-hip ratio with HP versus SP (−0.03 ± 0.03 vs. −0.01 ± 0.04; p < 0.05). Triglycerides decreased from baseline in both groups; however, the difference was not significant. Both HP and SP were well tolerated. This study demonstrated that in obese Chinese patients with hyperlipidemia, a protein-enriched MR diet resulted in significantly reduced waist circumference compared to a standard protein diet. Conclusion: This first study of protein-enriched partial meal replacement in a free-living Chinese population suggests a new and promising strategy for reducing abdominal obesity in China. © 2015, © American College of Nutrition Published by Taylor & Francis Group, LLC.
