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 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 study the immunophenotypic features of NK/T cell lymphoma in children and its association with Epstein-Barr virus (EBV) infection. Methods Five cases of children′s NK/T cell lymphoma were studied. CD45RO, CD3?, CD56, CD20, TIA-1 and granzyme B were detected by immunohistochemistry staining for investigating immunophenotype. The expression of EBV-latent membrane protein (LMP-1) were detected by immunohistochemistry. EBV-encoded RNA (EBER1/2) were detected by in situ hybridization (ISH). Results CD45RO, CD3?, TIA-1 and granzyme B were positive in 5 cases, CD56 was positive in 2 cases, while CD20 negative in 5 cases.EBER1/2 positive in 4 cases and LMP-1 positive in 3 cases.Conclusions NK/T cell lymphoma in children is strong associated with EBV infection,and EBV infection may play an important role in the pathogenesis of children NK/T cell lymphoma.

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 study the role of imbalance between transcription factors GATA-3 and T-bet expressions in causing acute lung injury after resuscitation in cardiac arrest model of swine.Methods Mter swine model of electrically induced cardiac arrest was established for 8 minutes,animals were resuscitated to get restoration of spontaneous circulation (ROSC).The swine with ROSC were randomly assigned to be sacrificed at 12 and 24 h after ROSC (n =8 in each group).CD3 +,CD4+ and CD8 + lymphocyte subsets were determined by flow cytometry,and the levels of serum IL-4,TNF-α,and IFN-γ were measured by using ELLSA.The protein levels and expressions of GATA-3/T-bet mRNA were detected in lung tissue by western blotting and quantitative real-time PCR device,respectively.Results Pulmonary function was significantly impaired after ROSC.CD4 + lymphocyte subsets (28.4 ± 2.3) ％,(24.1 ± 1.6) ％ and CD4 +/CD8 + (1.7 ±0.9),(1.5 ± 1.0) were significantly lower in the post-ROSC group compared with the sham-operated group (48.4±2.9)％,(51.1±5.4)％ (2.5±1.3),(2.7±1.1) (P＜0.05) at 12 h and 24 h after ROSC.The levels of serum IL-4 and TNF-α were markedly increased,while IFN-γ and IFN-γ/IL-4 were significantly decreased in the post-ROSC group compared with the sham-operated group (P ＜0.05) at 2-12 h after ROSC.Protein level and expression of GATA-3 mRNA in lung tissue were markedly increased,while those of T-bet were significantly reduced in the post-ROSC group compared with the sham-operated group (P ＜0.05) at 12 and 24 h after ROSC.Conclusions The lung immune dysfunction induced by imbalance between transcription factors GATA-3 mRNA and T-bet mRNA expressions may complicate in the process of post-resuscitation lung injury in a porcine model of cardiac arrest.

ObjectiveTo examine the relationship between ankle brachial index (ABI) and the extent of coronary stenosis and evaluate the usefulness of ABI to predict the extent of coronary stenosis in old patients.Methods118 patients with coronary angiography were examined by ABI and hemostatic factors evaluation in addition to history collection.ResultsABI was inversely and significantly associated with Gensini score. ABI reduced significantly (P<0.001) in the patients with 3-vessel or left main coronary artery disease (CAD). But there were no significant differences in ABI among the patients with no CAD, 1-vessel or 2-vessel CAD. The corresponding area under the ROC curve was 0.75±0.045, with 95% CI=0.67～0.84 (P<0.001) in ABI in 3-vessel or left main CAD. When ABI≤0.9, it had a relatively high specificity (89.1%) and sensitivity (55.6%) for predicting the presence of 3-vessel disease or left main CAD.ConclusionIn the old patients, ABI is inversely and significantly associated with the extent of coronary stenosis, and ABI≤0.9 has a relatively high specificity and sensitivity for predicting the presence of 3-vessel or left main CAD.

Objective To investigate the protective effects of Ulinastatin (UTI) and 1, 6 fructose diphosphate (FDP) on cerebral ischemia-reperfusion injury, and to discuss the protective mechanisms of UT1 and FDP on cerebral ischemia-repeffusion injury. Method Rabbit ischemia-repeffusion injury models were prepared by"four arteries occlusion". All rabbits were divided into four groups (n=6): control group, UTI (10 U/kg) group, FDP (200 mg/kg) group, UTI+ FDP group. Salt water, UTI, FDP and UTI + FDP were respectively used immediately after ischemia-reperfusion. Plasmic MDA and GSH-Px were measured at 30 minutes, 1 hour, 3 hours and 6 hours after reperfusion. Results The concentrations of plasmic MDA in every group were significantly improved compared with those in control group (P0.05 ), but significant difference could be found after 3 hours (P
