Objective To evaluate effects of pretreatment with glutamine on lung injury induced by intestinal ischemia/reperfusion(II-R) in rats. Methods Glutamine or saline were injected through tail vein before the model of intestinal ischemia/reperfusion in rats were established.The gene expression of intercellular adhesion molecule-1(ICAM-1) and heat shock protein-70(HSP-70) were tested with RT-PCR methods.The levels of heat shock protein-70 in the lung were measured with Western Blotting.Myeloperoxidase and malondialdehyde and pathological changes were also measured. Results The gene expression of heat shock protein-70 was enhanced by pretreatment with glutamine,and the level of HSP-70 was parallelly increased.Nevertheless,MPO,MDA and the gene expression of ICAM-1 were inhibited. Conclusion Pretreatment with glutamine can lessen the lung injury induced by intestinal ischemia/reperfusion in rats,the induction of HSP-70 gene may be one of the potential mechanisms.

Epstein-Barr virus (EBV) is a human herpesvirus associated with important human diseases, including infectious mononucleosis syndrome, malignant lymphoma, and nasopharyngeal carcinoma. The mechanism of EBV entry into host cells remains a subject of intensive research. After decades of study, researchers have identified several key proteins and different patterns of EBV intrusion into host cells. The viral surface glycoproteins, gp350/220, gp42, gB, gH, and gL, are involved in interactions with the CR2 receptor on the surface of B lymphocytes during viral entry. However, the majority of epithelial cells lack CR2 receptor expression, which makes viral invasion much more complex than in B lymphocytes. Three different models have been proposed to explain how EBV enters epithelial cells: (1) "transfer of infection", mediated by B lymphocytes or Langerhans cells; (2) EBV utilizes its own proteins during the process of fusion with the cell membrane; and (3) progeny virions arising from EBV-infected epithelial cells cross lateral membranes into adjacent epithelial cells. This review will discuss the relevant mechanism of viral entry into B lymphocytes and epithelial cells during EBV infection.

OBJECTIVEThere is little knowledge on whether there is clustering of inflammatory biomarkers, such as C-reactive protein (CRP), soluble intracellular adhesion molecule1-1 (sICAM-1), and angiotensin II (Ang II), in individuals with hypertension in the Mongolian population. In the present study, we investigated this relationship in a Mongolian population in China.

METHODSA total of 2589 adult Mongolians, aged 20 years and older, were recruited as study participants. Data on demographics, lifestyle, family history of hypertension, blood pressure, and blood chemistry were collected, and inflammatory biomarkers were measured in all participants.

RESULTSThe proportion of subjects with increased levels of two or three biomarkers was significantly higher in those with hypertension (21.0% and 6.0%, respectively) than in those with prehypertension (12.7% and 0.5%, respectively) or normotension (8.1% and 0.2%, respectively). The multivariate adjusted odds ratios (95% confidence interval) of hypertension associated with increased levels of one, two or three biomarkers were 0.94 (0.72-1.22), 1.42 (0.93-2.16), and 11.08 (1.45-84.80), respectively, compared with subjects with no increase in any biomarker.

CONCLUSIONHypertension was associated with a cluster of inflammatory biomarkers in the Mongolian population.

To explore the method of explants directly induced bud and establish the tissue culture system of mutiple shoot by means of direct organogenesis, core bud and daughter bulbs (the top of bud stem expanded to form daughter bulb) of T. edulis were used as explants and treated with thidiazuron (TDZ) and 1-naphthlcetic acid (NAA). The results showed that the optimal medium for bud inducted form core bud and daughter bulb were MS + TDZ 2.0 mg x L(-1) + NAA 4.0 mg x L(-1) and MS +TDZ 2.0 mg x L(-1) + NAA 2.0 mg x L(-1) respectively, both of them had a bud induction rate of 72.92%, 79.22%. The optimal medium for cluster buds multiplication was MS + TDZ 0.2 mg x L(-1) + NAA 0.2 mg x L(-1), and proliferation coefficient was 2.23. After proliferation, cluster buds rooting occurred on MS medium with IBA 1.0 mg x L(-1) and the rooting rate was 52.6%, three to five seedlings in each plant. Using core bud and daughter bulb of T. edulis, the optimum medium for adventitious bud directly inducted from daughter bulb, core bud and cluster bud multiplication were screened out and the tissue culture system of multiple shoot by means of direct organogenesis was established.

Objective To evaluate the effect of health education on the target population of iodine deficiency disorders (IDD) in Linxia Hui autonomous prefecture.Methods During 2006-2010,IDD health education was carried out in the target population of Linxia Hui autonomous prefecture,and IDD knowledge of 5th grade pupil and 20-50 years old child-bearing women were surveyed by stratified sampling and questionnaire survey methods to evaluate the effect of health education.Results After health education,IDD knowledge passing rate rose from 55.6％ (548/986) and 18.0％(118/657) to 90.0％(1103/1225) and 86.2％(687/797) among pupils and women,respectively.The awareness rates of iodine deficiency in causing goiter,mental retardation and birth born silly children,and the key role of iodized salt in controling IDD were increased from 79.2％ (781/986),76.5％ (754/986),51.7％ (510/986) and 82.3％ (811/986) to 88.8％ (1088/1225),85.6％ (1049/1225),68.7％ (842/1225) and 90.0％ (1103/1225) among pupils,and from 48.6％ (319/657),28.3％ (186/657),15.4％ (101/657) and 39.6％ (260/657) to 86.2％ (687/797),70.0％ (558/797),46.3％ (369/797) and 87.3％ (696/797) among women,and all the difference were significant,respectively.Belief rate held by students that health education can prevent iodine deficiency disorders was 87.3％ (1069/1225),and 52.9％ (648/1225) of the students told their parents about IDD.The rate of consciously purchase of qualified iodized salt was 87.1％ (694/797) after health education among women of childbearing age,and the consumption rate of iodized salt was 64.6％(515/797).More than 90％ of the people in relevant departments knew iodine deficiency disorders related knowledge,in particular,had a clear understanding of intellectual hazards caused by iodine deficiency,and actively supported and participated in health education in the prevention and control of iodine deficiency disorders.Conclusions Comprehensive health education measures taken through schools and religious organizations has promoted a shift in the behavior,beliefs and attitudes of its consciously purchase and consumption of iodized salt,and integrated knowledge,attitude and practice (KAP).It is a good model of health education through religious organizations in ethnic minority areas.It has promoted the health education feasibility and accessibility,and the effect is more durable.
