Long non-coding RNAs (lncRNAs) are involved in multiple cellular events, as well as in tumorigenesis. Colon cancer-associated transcript-1 (CCAT1) gene encodes an lncRNA whose over-activation was observed in an expanding list of primary human solid tumors and tumor cell lines, however its biological roles in acute myeloid leukaemia (AML) has not been reported yet at present. In this study, the aberrant upregulation of CCAT1 was detected in French-American-British M4 and M5 subtypes of adult AML patients. By gain- and loss-of-function analysis, we determined that CCAT1 repressed monocytic differentiation and promoted cell growth of HL-60 by sequestering tumor suppressive miR-155. Accordingly, a significant decrease in miR-155 level was detected in AML patients. Re-introduction of miR-155 into HL-60 cells restored monocytic maturation and repressed cell proliferation. Furthermore, CCAT1 could up-regulated c-Myc via its competing endogenous RNA (ceRNA) activity on miR-155. In conclusion, these results revealed new mechanism of lncRNA CCAT1 in AML development, and suggested that the manipulation of CCAT1 expression could serve as a potential strategy in AML therapy.

Few studies on the breakfast consumption habits of medical students in China have been carried out. The aim of the present study was to determine the prevalence of skipping breakfast and factors associated with skipping breakfast among medical students in Inner Mongolia of China, and to assist in the design of interventions to improve breakfast consumption habits of medical college students in this region. From December 2010 to January 2011 a cross-sectional survey was conducted among medical students in the Inner Mongolia Medical College using a self-administered questionnaire. The prevalence of skipping breakfast in relation to lifestyle habits was described and factors associated with breakfast consumption were identified using multiple logistic regression analysis. The overall prevalence of skipping breakfast was 41.7% and 23.5% for males and females, respectively. The Faculty of Medicine Information Management had the highest breakfast skipping prevalence. Logistic regression models found that the main factors associated with breakfast consumption habits among medical students were gender, class years of education, monthly expenses, faculty, appetite, sleeping quality, and the learning process; monthly expenses, sleeping quality, and the learning process showed a dose-dependent relationship. Breakfast consumption was associated with many factors, most importantly monthly expenses, sleeping quality and the learning process. The prevalence of skipping breakfast is significantly higher compared recently reported figures for medical students in western countries and other areas of China. Improvement of breakfast education should be considered for students in which higher monthly expenses, poor sleeping quality, or a laborious learning process have been identified.

OBJECTIVE: To assess the clinical therapeutic effect of acupoint catgut embedding at head-acupoint combined with massage of sole on refractory insomnia. METHODS: Forty-nine cases were randomly divided into an observation group (n=25) and a control group (n=24). The observation group was treated with acupoint catgut embedding at Baihui (GV 20), Shenting (GV 24), Sishencong (EX-HN 1), etc. combined with massage of sole; the control group was treaded with oral administration of Estazolam. The clinical therapeutic effects and scores for Pittsburgh Sleep Quality Index (PSQI) were assessed before and after treatment in the two groups. RESULTS: The total effective rate was 92.0% (23/25) in the observation group and 83.3% (20/24) in the control group with a significant difference between the two groups (P < 0.05). After treatment, there were significant differences in scores for various factor in the PSQI (P < 0.05, P < 0.01), except day time functional state in the control group. The improvements of sleep quality, time duration of patients going into sleep, sleep disorder and daytime functional state in the observation group were superior to those in the control group (P < 0.05, P < 0.01). The control group was superior to the observation group in the prolongation of hours of sleep (P < 0.05). CONCLUSION: Acupoint catgut embedding at head-acupoint combined with massage of sole can obviously improve sleeping quality and daytime functional state of the patients with insomnia.

We examined a possible association between HLA-A and -B polymorphisms and susceptibility to Henoch-Schönlein purpura (HSP) in Han and Mongolian children in Inner Mongolia, through a case-control study. Two hundred and sixty-eight unrelated children were enrolled, including 56 Mongolian and 50 Han children with HSP, 66 healthy Mongolian and 96 healthy Han children as a control group. HLA-A and -B alleles were indentified by PCR-sequence-specific oligonucleotide analysis and were further analyzed by PCR-sequencing-based typing (SBT). Frequencies of HLA-A*11, HLA-B*15 in Mongolian patients and HLA-A*26, HLA-B*35, HLA-B*52 in Han patients were higher than those in the corresponding control group (P < 0.05), while frequencies of HLA-B*07 and -B*40 in Mongolian HSP patients were lower than those in the control group (P < 0.05). Further analysis using PCR-SBT showed that all HLA-A*11 were HLA-A*1101, and most HLA-B*15 were HLA-B*1501 in Mongolian HSP patients. All HLA-A*26 were HLA-A*2601 and HLA-B*35 were mostly HLA-B*3503 in Han patients. There were more Han patients with severe manifestations than Mongolian patients (P < 0.05). Frequencies of HLA-A*26, HLA-B*35 and HLA-B*52 in Han patients were higher than in Mongolian patients (P < 0.05). We conclude that HLA-A*11(*1101) and -B*15(*1501) are associated with susceptibility to HSP in Mongolian children and HLA-A*26(*2601), HLA-B*35(*3503) and HLA-B*52 are associated with susceptibility to HSP in Han children. HLA-B*07 and -B*40 may be protective genes in Mongolian children. The different frequencies of HLA-A and -B in Mongolian and Han children may be responsible for the different manifestations in these two ethnic groups.

Activation of the peroxisome proliferator-activated receptor g (PPARg) improves insulin sensitivity and inhibits atherosclerosis. Whether PPARg2 Pro12Ala polymorphism affects myocardial infarction is not clearly understood. We investigated a possible association of PPARg2 Pro12Ala polymorphism with obesity and myocardial infarction in Han Chinese in Hohhot, Inner Mongolia, China. We included 121 subjects with myocardial infarction and 137 healthy controls in our study. Triglycerides, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol were measured. The following information was recorded for each subject: age, gender, body height, body weight, systolic blood pressure, and diastolic blood pressure; the body mass index was calculated. PCR-RFLP was used to examine Pro12Ala polymorphism. There were significant differences in clinical characteristics between myocardial infarction patients and healthy controls, except for diastolic blood pressure and triglycerides. The PP, PA/AA genotype frequencies were 88.4 and 11.6% in myocardial infarction patients and 95.6 and 4.4% in controls, respectively (P = 0.031). Individuals with the A allele had a significantly higher risk of myocardial infarction. The A allele was not an independent risk factor for obesity. We conclude that PPARg2 Pro12Ala polymorphisms are associated with increased risk for myocardial infarction in Han Chinese in Hohhot.

To investigate the effect of glucocorticoid on the expression levels of osteoprotegerin (OPG) and receptor activator of nuclear factor kappa B ligand (RANKL) mRNAs in rat femoral head and the antagonistic effect of Epimedium, and explore the mechanism of Epimedium in preventing glucocorticoid-induced femoral head necrosis. Forty-eight adult SD rats were randomized into glucocorticoid group, Epimedium group and control group. In the former two groups, the rats received intramuscular injection of 12.5 mg prednisolone twice a week, and in Epimedium group, additional 1 ml/100 g aqueous Epimedium extract (equivalent to 0.1 g/ml of the crude drug) was administered intragastrically once daily. The control group received only intramuscular saline injection. After 4 weeks of treatment, osteonecrosis of the left femoral head was detected by HE staining, and the right femoral head was sampled for detection of OPG and RANKL mRNA expressions using real-time quantitative PCR. In glucocorticoid, Epimedium and control groups, the mortality rate of the rats was 12.5% (2/16), 6.25% (1/16), 0 (0/16), and femoral head necrosis occurred at a rate of 71.43% (10/14), 26.67% (4/15), and 0 (0/16), respectively. In glucocorticoid group, the expression level of OPG mRNA was significantly lower, RANKL expression significantly higher, and OPG/RANKL ratio significantly lower than those in Epimedium and control groups (P<0.05). OPG, RANKL and their ratios showed no significant differences between Epimedium group and the control group. Epimedium can prevent glucocorticoid-induced femoral head necrosis probably by antagonizing glucocorticiod-induced abnormal expressions of OPG and RANKL mRNA.

We examined the distribution of major allelic variants of CYP2C9 and CYP2C19 in the Mongolian population of China and compared it with that of other populations. The polymorphisms of CYP2C9 (including the CYP2C9*1, CYP2C9*2 and CYP2C9*3 alleles) and CYP2C19 (including the CYP2C19*1, CYP2C19*2 and CYP2C19*3 alleles) were analyzed in 280 healthy unrelated Chinese Mongolian subjects, using a PCR-RFLP assay. The frequencies of CYP2C9*1, *2 and *3 alleles were 0.97, 0.00 and 0.03, respectively. The frequencies of CYP2C19*1, *2 and *3 alleles were 0.72, 0.24 and 0.04, respectively. We did not find any differences in the allelic distribution of these two genes between age groups. However, the genotype frequency of CYP2C9 *1/*3 was significantly higher in males than in females. Compared with other populations, we found that the allele frequencies of the CYP2C9*2 and CYP2C9*3 allelic variants in this Mongolian population of China were similar to those reported for other Asian populations, with significant differences compared to Caucasians and African-Americans.

To study the effect on endocrine system of female rats exposed to chronic arsenic. 50 female Wistar rats were randomly divided into five groups: control group, 0.05, 0.1, 0.2 and 0.4 microg/ml arsenic groups. The hormone levels were determined by RIA exposing arsenic for 32 weeks. The hormone levels of female rats were disorder in different arsenic groups. E2, P level increased and LH level decreased in arsenic groups compared to controls, but there were no significant differences( P > 0.05). FSH and PRL level increased in low arsenic group and decreased in high arsenic groups (P > 0.05). GnRH and Cort level increased in arsenic groups, and GnRH level obviously increased in 0.4 microg/ml group and Cort level obviously increased in 0.1 and 0.4 microg/ml groups (P < 0.05). The hormone levels were disordered in rats exposed to chronic arsenic.

Mongolians are known as heavy drinkers, and they have a high incidence of essential hypertension, which may be an associated pathology. We examined a possible association of essential hypertension and polymorphism of the aldehyde dehydrogenase 2 (ALDH2) gene in Mongolians from Inner Mongolia. Single nucleotide polymorphism rs671 of ALDH2 was detected by TaqMan PCR in 91 essential hypertensive patients (44 males and 47 females) and 70 healthy Mongolians (37 males and 33 females). Frequencies of the ALDH2*1/1 genotype and the ALDH2*1 allele in patients (91.2 and 95.6%, respectively) were significantly higher than in controls (78.6 and 89.3%; P < 0.05), while frequencies of ALDH2*1/2 genotype and ALDH2*2 allele in patients (8.79 and 4.4%) were much lower than in controls (21.4 and 10.7%; P < 0.05). Frequencies of ALDH2*1/1 genotype and ALDH2*1 allele in female patients (95.8 and 94.9%) were higher than in female controls (70.0 and 84.9%; P < 0.05); frequencies of the ALDH2*1/2 genotype and the ALDH2*2 allele in female patients (4.25 and 2.13%) were lower than in female controls (30.3 and 15.2%, P < 0.05). There was no significant difference in male subjects. ALDH2*2/2 was not found in any of the subjects. We conclude that ALDH2 polymorphism is associated with essential hypertension in Mongolians, especially in female Mongolians. ALDH2*2 was found to be a negative risk factor for essential hypertension in Mongolians from Inner Mongolia.

Over the past few years, nanoscale Chinese medicine has emerged as a new exciting field in which theoretical and experimental studies of structure and function of nanoscale Chinese drugs have become a focus, and the importance of quality standardization of nanoscale medicament of Chinese traditional medicine as specific drugs to the fundamental development in traditional Chinese drugs has begun to be recognized. In particular, Chinese medicine dispersion, surface potentials, envelopment ratio, loading drug amounts, in vivo metabolism dynamics, bio-distribution, drug-releasing in vitro, etc., have become a new interdisciplinary frontier in life science and Chinese traditional medicine. There is an increasing need for a more systematic study of the basic issues involved in traditional Chinese medicine and a more active participation of researchers in the application area of nanoscale traditional Chinese drugs. Some advances have been and are being made in nanoscale Chinese herbs, mineral medicine including mongolia drugs such as cinnabar, with enormous prospect in clinical disease therapy. Here we review some of the main advances in this field over the past few years, explore the application prospects, and discuss the concepts, issues, approaches, and challenges, with the aim of stimulating a broader interest in developing nanoscale Chinese medicine. © 2010 R.
