Objective To investigate the current status, performance,challenges and demands of the health management service-related institutions in China so as to provide evidence for effective policy-making. Methods A cross-sectional study design was used in this report. The health management service-related institutions were identified based on web site searching and government business registration records. Web or mail-based questionnaire was used for data collection. Telephone interview was conducted to confirm the validity and reliability of the data. Results Of 5744 health management service-related institutions in China,585 were investigated for type of organization, personnel profile, business strategy and investment. Since 2000, the number of health management service-related institutions in China had kept increasing in an average rate of 52%. The services included physical check, health education, and disease intervention,etc. Conclusions In China,health management is still at its early stage although an increasing trend could be found and a large number of related- institutions have emerged. However, health management system in China still faces the challenge of poor professional services and insufficient healthcare providers.

AIM: To evaluate the efficacy and complications of intravitreal injection of triamcinolone acetonide ( TA ) for the treatment of macular edema caused by pre-retinal membrane of the macular.
METHODS: Totally 23 patients ( 24 eyes ) with macular edema caused by pre-retinal membrane of the macular were treated withintravitreal injection of 4mg TA. Best-corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) , slit - lamp examination, fundus fluorescein angiography ( FFA ) and optical coherence tomography (OCT) were performed before and after treatment. The SPSS 12. 0 software was used for statistical analysis.
RESULTS: After 10, 30, 90d of treatment of TA, as compared with before treatment, visual acuity improved significantly ( P<0. 05 ), and central macular thickness (CMT) was significantly thinner (P<0. 01). The average central macular thickness decreased from 522 ± 126μm before treatment to 264±115μm, 245±128μm, 286±131μm at 10, 30, 90d after treatment. Macular edema reduced. IOP increased in 7 eyes ( 29%) , one cataract case, no other complications associated with vitreous injection.
CONCLUSION: Intravitreal injection of TA in the treatment of macular edema caused by pre - retinal membrane of the macular is simple, safe and easy to operate. It can quickly reduce macular edema, and improve the visual acuity in the short term. Part of patients may recur after injection in the first half of the year.

OBJECTIVETo observe the effect of acupuncture along affected meridian on the mem- brane metallo-endopeptidase (MME) gene expression of migraine patients without aura (MO) of Gan-yang hyperactivity syndrome (GYHS).

METHODSTotally 20 MO patients of GYHS were randomly assigned to the acupoint group (acupuncture along affected meridian) and the non-acupoint group, 10 cases in each group. Needling was performed once per day for 10 consecutive days. Gene chip technology was used to obtain two sets of gene expression profiles and analyzed using Gene Ontology (GO).

RESULTSIn the acupoint group, MME gene expression decreased after needling (P = 0.0023).That gene was rich in the beta-amyloid metabolic process (P = 3.16E-05) and the peptide metabolic process (P = 0.009612). Its expression was not seen in the non-acupoint group.

CONCLUSIONThe effect of point selection along affected meridian could be achieved possibly by regulating the MME gene expression.

OBJECTIVETo investigate the changes of the cardiac hemodynamics after acute high altitude exposure in healthy young males and the relationship with acute mountain sickness(AMS).

METHODSLeft ventricular function and oxyhemoglobin saturation (SaO2), heart rate (HR), blood pressure (BP) were measured in 218 healthy young males before and after high altitude exposure within 24 h respectively. According to the lake louise score criteria, the subjects were divided into two groups: acute mountain sickness group (AMS group) and non acute mountain sickness group (non-AMS group).

RESULTSHR, diastolic blood pressure (DBP), mean arterial pressure (MAP), left ventricular ejection fraction (LVEF), stroke volume (SV), stroke index (SI) cardiac output (CO), cardiac index (CI) were significantly increased upon acute high altitude exposure (P < 0.05). Whereas SaO2 and end-systolic volume (ESV) were significantly decreased (P < 0.05). In addition, HR, systolic blood pressure (SBP) and MAP in AMS group were significantly higher than those in non-AMS group (P < 0.05). But stroke index (SI) and end-diastolic volume (EDV) in AMS group were significantly lower than those in non-AMS group (P < 0.05).

CONCLUSIONCardiac function in healthy young males upon acute high altitude exposure was enhanced. EDV, HR and SI might become the indexes of predicting the acute mountain sickness in the future.

OBJECTIVETo identify HLA-A0201 restricted cytotoxic T lymphocyte (CTL) epitopes derived from the hepatitis B virus e (HBe) antigen, for future use in a specific immunotherapy based on the identified epitope(s).

METHODSHBe gene sequences from the hepatitis B virus serotypes with the highest frequencies in China were analyzed by bioinformatic web-based interfaces for quantitative motif prediction, extended motif prediction, and peptide super-motif prediction. Four candidate peptides were identified: HBe1, HBe2, HBe3, and HBe4. The affinities of each were tested in vitro with T2 cells, which lack the transporter-associated with antigen transport (TAP) protein but express low levels of the MHC class I surface molecule, and measured by the T2 binding assay and DC50 assay. Flow cytometry was used to detect the fluorescence index of control and experimental groups.

RESULTSThe peptides HBe1 (LLWFHISCL), HBe2 (YLVSFGVWI), HBe3 (CLTFGRETV), and HBe4 (DLLDTASAL) were identified and tested as candidate targets. HBe2 and HBe3 showed higher HLA-A0201 affinity. HBe1, HBe2, and HBe3 showed better binding stability.

CONCLUSIONTwo peptides based on HBe antigen, YLVSFGVWI and CLTFGRETV, possess both sufficient binding affinity and stability and may represent useful HLA-A0201-restricted CTL epitopes. Further study is needed to determine the immunogenic properties of these two peptides in vivo.
