Objective: To study the influence of inflammatory cytokine TNF-? on the expression of adhesion molecules and specific markers of rat MSCs, and to study the optimal stimulation of MSCs with inflammatory factors in inducing adhesion molecule expression which promotes migration of MSCs to the ischemic area in liver. Methods: The MSCs stimulated with different concentration of TNF-? were detected for adhesion molecules and stem cells markers on cell surface with the method of flow-cytometry, MSCs which were stimulated with the optimal concentration of TNF-? and labeled with 1, 1-Dioctadecyl-3, 3, 3, 3-tetramethylindocarbocyanine Iodade(DiI)were delivered intravenously to the rats whose liver was injured by ischemia, the liver function of the experimented animals were tested, and liver samples in the ischemic area were obtained, the number of MSCs was counted under a fluorescent microscope. Results: Stimulated with TNF-?, MSC ex-pression of VCAM-1 increased, while that of stem cell markers did not change markedly. Exposed to lower concentration of TNF-?, the adhesion ability of MSCs obviously increased and more MSCs rested in the ischemic areas in the rat liver, compared to the control groups. Conclusions: TNF-? can increase the expression of VCAM-1 on rat MSCs while exert little effect on the stem cell character of MSCs. Suitable concentration of TNF-? can promote MSCs migration to the damaged tissue, which provides rationale for the treatment of liver disease.

Objective To explore the molecular mechanisms of primary amenorrhea by using arrayCGH technology. Methods Ten patients with primary amenorrhea and 10 female volunteers with regular menstrual cycles as healthy controls were selected. All patients and control samples were analyzed by conventional chromosome analysis (G-banding technology) and array-CGH technology, respectively. ArrayCGH was performed using Affymetrix Cytogenetic 2. 7M arrays following the manufacturer's standard protocol. Results Both the patient group and control group analyzed by conventional G-banding karyotype technology showed a negative result with a normal female karyotype: 46, XX. The result of array-CGH analysis demonstrated a microdeletion of approximately 110 000 bp located at the end of the short arm of X chromosome [46, X, del (X) (p22. 33 )] were identified in 5 patients, which was not detected in the control group. All healthy control samples by array-CGH analysis showed no pathological DNA copy number variation. Conclusions Array-CGH technology can improve the diagnosis rate of chromosomal disease at the DNA level. It is necessary to provide array-CGH for higher resolution genetic analysis of idiopathic primary amenorrhea patient who can not be identified by conventional technology.

Objective To explore whether the increase of body mass index (BMI) , waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR) can predict a higher risk of developing hyperglycemia. Methods A population-based cross-sectional study was conducted on local residents above 35 years of age in three urban districts and one rural county in July 2004. The subjects who were non-hyperglycemia in the baseline survey were selected to follow the survey in July 2007. Multivariable logistic regression analysis and area under curve (AUC) of receivcr-operating characteristics (ROC) were used to evaluate the predictive value of BMI, WC, WHR and WHtR. Results Of 3727 subjects without hyperglycemia who had completed in the baseline survey, 3031 of them participated in the follow-up survey, with a follow-up rate of 81.3%. The Three-year cumulative incidence of hyperglycemia was 6.7%,with male 6.3% and female 7.0%. By multiple linear regression, on average, an increase in BMI, WC, WHR, WHtR of 1 unit was associated with a 0.015 mmol/L, 0.023 mmol/L, 1.923 mmol/L, 2.382 mmol/L increase in fasting plasma glucose, respectively. The risk of developing hyperglycemia increased along with the increase of all the four indexes. When compared with other three indexes, the group which WHtR was more than 0.5, had the highest risk (male OR= 1.998, 95%CI:1.231-3.212, female OR= 1.832,95%CI: 1.157-2.902) of developing hyperglycemia. Data from ROC curve analysis showed that the AUC of WHtR was the highest in both males and females. Conclusion The increase of BMI, WC, WHR and WHtR could predict the higher risk causing the development of hyperglycemia. WHtR might serve as a simple but most effective index of hyperglycemia.

OBJECTIVETo study the current situation of depression and anxiety from patients with hypertension as well as to provide reference for the development of control and prevention program.

METHODSParticipants older than 35-year including both hypertensive patients and healthy controls were randomly selected in 2 communities of Pukou district in Nanjing through Health Behavior Survey. All the subjects were assessed by the Zung's self-rating depression scale (SDS) and the Zung's self-rating anxiety scale (SAS).

RESULTSRaw score and index score of SDS and SAS were both significantly (P < 0.01) greater in hypertensive patients than in healthy control group. The prevalence of depression of 17.9% and anxiety of 9.5% in patient group were found significantly higher than that in healthy control group as 11.5% and 4.3%. Data from logistic regression model analysis showed that depression and anxiety were possible risk factors of hypertension (OR = 1.677, 95% CI: 1.013-2.776; OR = 2.451, 95% CI: 1.228-4.894). There was a combined effect seen between depression and anxiety (OR = 5.238, 95% CI: 2.356-11.664) but interaction did not appear.

CONCLUSIONDepression and anxiety were possibly associated with hypertension and more attention needs to be paid to the mental health situation of hypertensive patients in order to improve their quality of life.

To study the expression of angiotensin converting enzyme 2 (ACE2) and angiotensin (Ang) 1-7 specific receptor Mas protain in renal blood vessels of metabolic syndrome ( MS) rats and its anti-oxidative effect. A total of 80 male SD rats were divided into four groups: the normal control group (NC, the same volume of normal saline), the MS group (high fat diet), the MS + Astragali Radix group (MS + HQ, 6 g x kg(-1) x d(-1) in gavage) and the MS + Valsartan group (MS + XST, 30 mg x kg(-1) x d(-1) in gavage). After four weeks of intervention, their general indexes, biochemical indexes and blood pressure were measured; plasma and renal tissue Ang II, malondialdehyde (MDA) and superoxide demutase (SOD) levels were measured with radioimmunoassay. The protein expressions of Mas receptor, AT1R, ACE and ACE2 were detected by western blot analysis. According to the result, compared with the NC group, the MS group and the MS + HQ group showed significant increases in systolic and diastolic pressures, body weight, fasting glucose, fasting insulin, triglycerides, free fatty acid and Ang II level of MS rats (P < 0.05). The MS + XST group showed notable decreases in systolic and diastolic pressures than that of the MS group. The MS group showed significant increases in the SOD activity and NO level and decrease in the MDA level after being intervened with Astragali Radix. ACE and AT1R protein expressions in renal tissues of the MS group were higher than that in the NC group, but with lower ACE2 and -Mas receptor expressions (all P < 0.05). Compared with the MS group, the MS + HQ group showed significant increase in Mas receptor expression in renal tissues, whereas the MS + XST group showed notable decrease in AT1R (all P < 0.05). In conclusion, Astragali Radix can increase the Mas receptor expressions in renal tissues, decrease ACE expression and change local Ang II, MDA, NO and SOD in kidneys, so as to protect early damages in renal tissues.

OBJECTIVE: To analyze FOXC2 gene variant in a family affected with lymphodema-distichiasis syndrome (LDS). METHODS: Peripheral blood samples were collected for the extraction of DNA and protein. Whole-exome sequencing was carried out to detect variants in the proband. Suspected variant was validated by Sanger sequencing. Western blotting was used to detect changes in protein expression. RESULTS: The proband and his mother were both found to carry a heterozygous nonsense variant c.177C>G (p.Tyr59X) of the FOXC2 gene, which was previously unreported. Down-regulated expression of FOXC2 was detected by Western blotting. Prenatal ultrasonography of the fetus indicated increased nuchal thickness. Amniocentesis was performed at 21+1 weeks of pregnancy, genetic testing suggested that the fetus also carried the c.177C>G variant. CONCLUSION The patients' condition may be attributed to the heterozygous nonsense variant c.177C>G of the FOXC2 gene, which resulted in a significant decrease in FOXC2 expression. Increased nuchal thickness may also be related with decreased FOXC2 expression. Above finding has expanded the variant spectrum of the FOXC2 gene.
