Objective:
To explore the application of grid health education model in improving college students health literacy.
Methods:
The clustered stratified random sampling method was used among the pre-formative education freshmen in a Xi-an university, with 1 123 students randomly selected totally. The intervention group (578) received health literacy education based on grid health education model, while the control group (545) receuved the original health education model. The effect of gird model of health education on health literacy was compared between two groups of college students after one-semester intervention.
Results:
Insufficient health literacy was found among freshmen participants in Xi an(17.12%, 17.61%); health literacy on prevention and treatment of chronic diseases (15.92%, 16.70%) was significantly lower than the national average level of urban residents(22.73%). Health literacy of the two groups of college students was significantly improved(47.75%, 27.71%, χ 2=20.50, 5.47, P<0.05). The grid health education model had significant effects in improving health literacy among college students, except for health literacy on safety and emergency(P<0.05).
Conclusion
Health literacy of college students is insufficient compared to that of urban residents in China. Grid model of health education model is superior to conventional health education model, which is in line with the requirements of health education in colleges in the new era.

OBJECTIVETo investigate clinical effects of three-column reconstruction via single posterior approach for the treatment of unstable thoracolumbar fractures accompanied by posterior column injury.
METHODSFrom December 2008 to May 2010,three-column reconstruction via posterior approach was implemented to 21 patients with unstable thoracolumbar fractures accompanied by posterior column injuries. There were 13 males and 8 females, ranging in age from 23 to 54 years old(averaged,35.5 years old). Injured vertebrae: 1 patient had injury in T11, 4 patients had injuries in T12, 8 patients had injuries in L1, 5 patients had injuries in L2, 3 patients had injuries in L3. The Cobb angle was (25.34 +/- 3.42) degrees. The operation time,blood loss during operation, Cobb angle and the bony fusion were observed.
RESULTSTwenty-one patients were followed up, and the duration ranged from 24 to 27 years old, with an average of 25.6 months. The operation time ranged from 135 to 275 min, with a mean of 185 min. The blood loss during operation ranged from 700 to 1 650 ml (averaged, 870 ml). All the patients had complete decompression. Postoperative Cobb angle was (4.01 +/- 2.03) degrees, and (4.34 +/- 2.38) degrees at the latest follow-up. All the patients got bony fusion.
CONCLUSIONTo the patients with unstable thoracolumbar fractures accompanied by posterior column injuries, three-column reconstruction via single posterior approach has both anterior approach and posterior approach advantages, which can obtain excellent clinical outcomes.

OBJECTIVETo evaluate the efficacy and adverse reaction of total glucosides of paeony (TGP) combined with sulfasalazine (SSZ) in the treatment of ankylosing spondylitis (AS).
METHODSSixty-seven AS patients were randomly assigned to 2 groups: the treatment group (34 cases) treated with TGP and SSZ, the control group (33 cases) with methotrexate (MTX) and SSZ. Changes of clinical efficacy related indexes including lumber pain index, morning stiffness time, peripheral joint pain index, thoracic expansion, Schober test, Bath AS disease active index (BASDAI), Bath AS functional index (BASFI), the levels of erythrocyte sedimentation (ESR) and C-reactive protein (CRP), and X-ray of sacroiliac joint were observed.
RESULTSThe clinical efficacy indexes were significantly improved after treatment in the two groups (P < 0.05). Except that the improvement of lumber pain index and peripheral joint pain index was better in the treatment group than that in the control group (P < 0.05), no significant difference was found in the other indexes between the two groups. The occurrence of adverse reation was less in the treatment group than in the control group (P < 0.05).
CONCLUSIONTGP treatment combined with SSZ shows favorable effect on AS with less and milder adverse reaction.

BACKGROUNDMumps virus infection is a potentially serious viral infection of childhood and early adulthood. In China, live attenuated S(79) mumps vaccine has been licensed for pediatric use since 1990. The objective of this study was to determine the effectiveness of live attenuated S(79) mumps vaccine against clinical mumps in outbreaks.
METHODSCases were selected from mumps outbreaks in schools in Guangzhou between 2004 and 2005. Each case was matched by gender, age and classroom. Vaccination information was obtained from Children's EPI Administrative Computerized System. Vaccine effectiveness (VE) was calculated for 1 or 2 doses of S(79) vaccine with 95% confidence intervals (CI).
RESULTSOne hundred and ninety-four cases and 194 controls were enrolled into the study. VE of the S(79) mumps vaccine for 1 dose versus 0 confer protection 80.4% (95% CI, 60.0%-90.4%) and VEs against mumps in outbreaks for 1 dose of mumps vaccine are similar among those children aged 4-9 years and aged over 10 years old.
CONCLUSIONThe live attenuated S(79) mumps vaccine can be effective in preventing clinical mumps outbreaks.

Background and purpose:Ionizing radiation(IR) activates the early growth response- I(Egr1) promoter through specific cis-acting sequences termed CArG elements by production of radical oxygen intermediates(ROls).Egr-EG,an expression vector pCIneo containing CArG elements cloned upstream of the cDNA for human recombinant GM-CSF,was used to treat hematopoietic damage due to chemotherapy.Commonly used chemotherapeutic agents can cause tumor cell death by producing DNA damage and generating ROIs.We therefore hypothesized that clinically employed chemotherapeutic agents that increase ROIs could also be employed to activate Egr-EG in a chemoinducible gene therapy strategy.This study was done to explore the chemo-protective effect of the expression of hematopoietic growth factors regulated by Egr-1 promoter on chemotherapy induced damage. Methods:The human GM-CSF cDNA and EGFP cDNA were linked together with internal ribosome entry site(IRES) and then inserted into the eukaryotic expression vector pCI-neo with the Egr-1 promoter(Egr-EG),and was further transduced into human bone marrow stromai cell lines HFCL(HFCL/EG).The HFCL/EG cells were transplanted i.v.into BI6 melanoma in C.B-17 combined immunodeficient(SCID) mice.5-FU was given i.p.on day 3 and 4.The white blood cell amount in peripheral blood,the expression of EGFP and GM-CSF in human stromal cell engrafted in recipient mice were detected by flow cytometry,RT-PCR,Western blot and colony-forming units for granulocytes and macrophages(CFU-GM),respectively.Results:In contrast to the two control groups,HFCL/EG(the Egr-regulatory element-derived expression of GM-CSF gene therapy) resulted in a proportional increase in the number of the white blood cell after chemotherapy,no significant diifferences were found for CFU-GM in bone marrow cells and the inhibition ratio on tumor in recipient mice.Chemotherapy could markedly increase the expression of EGFP and GM- CSF mRNA/protein as compared with that of non-chemotherapy control groups and HFCL group.Conclusion: Chemoinducible GM-CSF gene therapy regulated by Egr-1 promoter can ameliorate the toxic effect on 5-FU chemotherapy-inducible hematopoietic damage.
