OBJECTIVETo compare the reactogenicity and serology between influenza subunit vaccine and split vaccine.
METHODSA randomized, double-blind study was carried out among children (age 6 - 12 years) in order to compare the safety and immunogenicity of an influenza inactivated subunit vaccine (Agrippal, Chiron Vaccines) with that of a split vaccine (Flurix, GSK).
RESULTSA total of 499 subjects were vaccinated and included in the safety analysis. A total of 249 subjects received Agrippal and 250 received Flurix. All subjects were kept under medical observation for 30 minutes in order to check the evidence of having any immediate local and systemic reaction. Daily observation records were collected during the 3-day follow-up after vaccination. 6.4% of the cases with fever >or= 37.5 degrees C was reported in the Flurix group, but 2.4% in Agrippal group which was significantly less than the former group (P > 0.05). Blood samples (the D0 pre- and D23 post-vaccination sera) were collected from 224 of Agrippal group and 223 of Flurix group and analysed by the haemagglutination inhibition (HI) assay. Agrippal and Flurix induced similar seroprotection (HI titer >or= 1:40, H1N1 99.6% vs 100.0%; H3N2 99.1% vs 99.1%) and seroconversion (4-fold increase, 95.1% vs 97.8%; H3N2 74.5% vs 79.8%) rates and geometric mean titer (GMT) increase (16.0 vs 21.0; 5.4 vs 6.4) against the two A subtypes. A similar seroprotection rate (94.2% vs 96.4%) and GMT increase (21.2 vs 18.2) against the influenza B strain were also noticed in both vaccines. No significant difference was found in the results of immunological assay between the two vaccines (P < 0.05). A lower seroconversion rate against B strain was observed in Agrippal group than in Flurix group (91.1% vs 97.3%).
CONCLUSIONIn terms of safety, both vaccines were generally well tolerated. The fever reaction was less frequently seen in the Agrippal group. Both vaccines induced an effective immune response in the vaccines.

OBJECTIVETo evaluate the acceptability of self-management project for patients with hypertension and the short term result, and provide the evidence of preventing and controlling hypertension using chronic disease self-management.
METHODSVoluntary patients with hypertension were grouped into the control and experimental groups after matching age, sex, education levels and the number of chronic diseases between the two groups. Data collected through questionnaire after intervention were compared with the baseline data through analysis of covariance and chi(2) test.
RESULTSRate of awareness for the diagnostic criteria of hypertension, risk factors and associated diseases increased by 56.4%, 50.4% and 37.6% respectively, and the rate of high salt diet intake, body mass index and the times of visiting doctors decreased by 27.1%, 0.8 kg/m(2) and 2.7 times on average in experimental group, as compared with control group. The health status (energy, fatigue, shortness of breathe, pain) improved (P < 0.05). In the similar comparison, the rate in which the hypertensive patients took antihypertensive medicine increased by 20%, and the scores of cognitive symptoms management and of patient communication with physician increased by 3.9 and 1.1 points respectively. The rate of compliance to medication increased by 21.5% compared with themselves.
CONCLUSIONThe awareness rate of hypertensive patients on knowledge and on unhealthy life style improved after implementing the self-management program. Their emotion, healthy behavior, health status and symptoms related to hypertension improved. Data showed that it was effective for hypertensive patients to use chronic diseases self-management.

One highly pathogenic strain of avian influenza virus (AIV) was isolated from goose in China recently, designated as F-3. In order to study the viral entry mechanisms, the hemagglutinin (HA) gene of H5N1 subtype AIV isolate was amplified by RT-PCR, and then cloned into pGEM-T vector and sequenced. The sequencing result has logging in GenBank, the accession number was AY639405. The HA gene of F-3 had a complete open reading frame (ORE) and composed of 1707 nucleotides, coding for 568 amino acids. The deduced amino acid sequence at the cleavage site of the HA protein was RKKR GLF, matched to the characteristic of virulent avian influenza strain. The HA gene were subcloned into pcDNA3, so the plasmid pcDNA-HA can express the HA glycoprotein. Co-transfected pcDNA-HA, pHIT60 (include Murine Leukemia Virus structural genes, namely gag and pol) and pHIT111 (retroviral vector genome,containing LacZ as a reporter) into 293T cells. The retroviral supernatant were harvested 48 hours post-transfection, filtered through 0.45 micromol/L filter. The supernatant were used to analysis the characteristic of the pseudotyping virions by Western blotting and infection test. Western blotting revealed the HA glycoproteins can be expressed on the virions, indicated the glycoproteins were incorporated onto the retroviral virions. Infection test were performed on 293T, NIH3T3 and COS-7, all the three kinds of cells infected were lacZ positive, indicating viral entry, and revealed the pseudotype virions of MuLV-HA were infectious. So the pseudotype system of MuLV particles with AIV Hemagglutinin proteins were setted up and it can be used to study the entry of avian influenza virus isolated from goose in China.

UNLABELLEDOBJECTIVE To understand the demands and influencing factors on the community-based health care service (CHS) among the elderly and to provide evidence of implementing health service for them
METHODSCluster sampling method was used on 717 persons aged 60 and above in Yanjiao Developing Area. A survey was carried out, using questionnaire and focus group discussion approaches.
RESULTSData showed that a two-week prevalence of diseases was 56.3% while the overall prevalence of chronic diseases was 92.1% with 70.0% of them suffering from more than two kinds of chronic diseases. The rates of ADL and IADL loss were 1.8% and 7.0% respectively with 37.0% of them sought medical consultation in the past two weeks. Major reason affecting the use of health service was low income. 57.7% of the elderly expressed their willingness of accepting CHS with the strongest demands as regular physical check-up, health education and consultation, specialized care services, home care service while major reasons hindering the acceptance of CHS could be referred to self-perception on good stamina and lack of awareness to CHS.
CONCLUSIONThe demands of CHS in the elderly were greater than those in general population that called for CHS programs to be acceptable and relevant to meet the different needs.
