Objective To analyze the dietary behavior and blood lipid profiles of the local elderly Tibetans and Han people living in Tibet and in Beijing,and to advise some steps to promote the health of local elderly Tibetans.Methods We collected the data of diet and blood lipids of the local Tibetan and Han people living in Tibet and in Beijing aged over 35 yrs by the method of migration epidemiology.Results The diet pattern of Tibetan was high intakes of coarse grains(219.8?123.3 g/day),meat(226.2?210.1 g/day),and wine(580.8?1 049.0 g/day),but low intakes of fresh vegetable & fruits(217.8?160.4 g/day).The prevalence of hypertriglyceridemia(5.0%) and low high-density lipoprotein cholesterol(3.1%) of Tibetan was lower than that of other two groups(elderly Han people in Tibet 22.5% and 10.7%;elderly Han people living in Beijing 14.7% and 8.4%,all P

Objective To build a more perfect serum protein ifngerprint models for early diagnosis of ganglioneuroblas-toma (GNB) in children. Methods Thirty children with GNB and 30 normal control children were recruited. Serum samples were collected. Nonspeciifc serum protein was detected and studied by MB-WCX processing, SELDI-TOF-MS mass spectrom-etry system and MALDI-TOF/TOF platform. Results Through the SELDL-TOX-MS processing, a peak at 5920 m/z protein markers, and the expression of the markers was high in GNB children (6180.6±2328), compared with normal control children (419.1±493.3), the difference was statistically signiifcant (P<0.05);MALDI-TOF/TOF platform showed that the protein with a peak at 5920 m/z is identiifed as ApoC-Ⅲ. Conclusions m/z peak of 5920 protein is suggested as speciifc biomarker of GNB in children, can provide signiifcant reference for early diagnosis of ganglioneuroblastoma, and prognostic monitoring.

Objective:To analyze the mechanism on integration of health care services at the county and town-ship level from the perspective of stakeholder theory. Methods: The stakeholder interest demand was determined by word frequency analysis of interview data from stakeholders in the three regions of Qianjiang, Huangpi, and Zhen-jiang;the degree of attention and gains and losses of stakeholders towards various demands was investigated from the three regions through interest demand questionnaires;the impact of demand benefits on behavioral responses has been evaluated through comprehensive evaluation theory and game theory. Results:Regional integration policies reflect the interest demands of stakeholders in varying degrees; the higher were the scores of demand benefits in interest de-mands questionnaires, the stronger was the willingness of stakeholders to coordinate integration policies. Conclusion:The policies of integration of health care services in rural China should consider all stakeholder interest demands;the better the interest demands of the stakeholders are satisfied, the stronger their motivation for integration reform will be, which may affect the implementation effects of local integration reforms to some extent.

Objective To observe the effect of lovastatin on plasminogen activator inhibitor -1 (PAI-1) and collagen type Ⅳ in rats with glomerularsclerosis induced by adriamycin,and to discuss its mechanism of protective effects on kidneys.Methods Twenty-four male Wistar nephritic rats induced by adriamycin were randomly divided into 3 groups:control,hyperlipidemia and lovastatin treatment group.They were fed 12 weeks.Urinary protein excretion and serum lipid were assayed,then renal glomerularsclerosis index,the expression of PAI-1 and collagen type Ⅳ were observed.Results Serum total cholesterol,triglycerides,low-density lipoprotein,urinary protein excretion,renal glomerularsclerosis index were significantly lower in treatment group than those in hyperlipidemia group.Expression of PAI-1 and collagen type Ⅳ,and number of foamcells were also sharply lower in treatment group than those in hyperlipidemia group.Conclusions Lovastatin not only reduces proteinuria,improves renal function,but also modulates glomerularsclerosis by inhibiting activity of PAI-1 and decreasing accumulation of collagen type Ⅳ.The mechanism of renal protective effect is independent of a reduction of circulating cholesterol.

OBJECTIVE: To study the expressions of focal adhesion kinase (FAK) and phospho-FAK( p-FAK) during skin incised wound healing and the applicability of time-dependent expressions of FAK and p-FAK. METHODS: The expression of FAK and p-FAK in cutaneous incised wound in mouse were investigated by immunohistochmeistry and Western blotting. RESULTS: FAK and p-FAK expression were detected in polymorphonuclear cells (PMNs) in the wound and adjacent regions 3 hours post-injury. The expressions of FAK and p-FAK were detected in a large number of infiltrating PMNs and some of mononuclear cells (MNCs) from 6 to 24 hours after injury. The MNCs and fibroblastic cells (FBCs) accounted for most part of the FAK and p-FAK positive cells from 3 to 14 days after injury. The numbers of FAK-positive cells increased continuously, reaching a peak at post-injury day 3, and then started to decrease from post-injury day 5 to 14. The changes of p-FAK-positive cells were similar to that of the FAKs, and reached a peak at 12 hours after injury. CONCLUSION Both FAK and p-FAK displayed a time-dependent expression during skin incised wound healing in mouse, with p-FAK being superior to FAK. Both FAK and p-FAK may potentially be used as new markers for determination of the wound interval.

Objective To discuss the impact of repeated contrast media exposure on renal function in patients who received coronary angiography ( CAG) or percutaneous coronary intervention ( PCI) within 1 week after CTA of coronary ateries. Methods A total of 258 patients who received CAG or PCI after coronary CTA were divided into the study group ( n=132, patients had CAG/PCI within 1 week after CTA) and the control group ( n=126, patients had CAG/PCI 1-2 weeks after CTA). Serum creatinine, cystatin C and estimated GFR were tested before and on day 1, 2 and 3 after procedures. The occurance of contrast-induced nephropathy ( CIN ) was recorded. Resu1ts The baseline clinical characteristics of the patients between the two groups had no significant difference. Preoperative and postoperative serum creatinine, cystatin C and eGFR values on day 1, 2 and 3 had no significant difference between the two groups (all P﹥0. 05). There was no significant difference in the incidence of CIN between two groups (5. 3% in the study group vs. 4. 8% in the control group, P﹥0. 05 ) . Conc1usions It is safe and feasible for patients with eGFR≥60 ml/( min?1. 73 m2 ) to undergo CAG or PCI within 1 week after coronary CTA.
