From the view of realizing health justice,The paper discusses the consistent objective between health justice and "Primary Health Care for all".It put forward and expound that PHC is the effective path of realizing health justice in new period,and some proposal which strengthen government's responsibity and function about PHC,as well as develop the health service in community both in urban and rural areas,with the focus on PHC in rural areas.

Objective To investigate the effects of Erigeron breviscapus Hand Mazz(EBH) on learning and memory dysfunction in mice with cerebral ischemia/reperfusion injury.Methods 40 mice were randomly divided into control group, sham operated group, model group and EBH group, with 10 mice each. Mice model of cerebral ischemia/reperfusion injury was established by bilateral common carotid artery blocking. 7 days before and after operation, the mice in EBH group were injected I.p.with EBH injection 0.15 ml/d, while those in other groups were injected I.p. with saline 0.15 ml/d. The learning and memory function was tested by Morris water maze.Results The latent period in the model group was longer than that in the normal group and the sham operated group (P<0.05). EBH could shorten the latent period significantly as compared with those in the model group (P<0.05).Conclusion EBH can improve learning and memory function in cerebral ischemia/reperfusion injured mice.

Methods48 mice were randomly divided into control group, sham operated group, model group and Aniracetam group, with 12 mice each. Mice model of cerebral ischemia/reperfusion injury was established by bilateral common carotid artery blocking. The learning and memory function was tested by Morris water maze.ResultsThe latent period in the model group was longer than that in the normal group and the sham operated group (P<0.05). Aniracetam could shorten the latent period significantly as compared with those in the model group (P<0.05). ConclusionAniracetam has effects in improving learning and memory function in cerebral ischemia/reperfusion injured mice.

OBJECTIVETo observe the effect of Zhibai Dihuang Decoction (ZDD) on mRNA and protein expressions of transient receptor potential family vanilloid subtype 1 (TRPV1) and transient receptor potential family vanilloid subtype 5 (TRPV5) in Ureaplasma urealyticum (UU)-infected rat semens and spermatogenic cells, and to explore the pathomechanism of UU-infected infertility and the intervention of ZDD.

METHODSTotally 45 were randomly selected from 60 4-5 months old SD rats. UU testicular infected animal models were set up after bladder inoculation of UU suspension. The remaining 15 rats were simultaneously injected with normal saline as a normal control group. After a successful modeling, UU infected model rats were randomly divided into the model group, the azithromycin group, and the ZDD group, 15 in each group. Rats in the ZDD group were administered with ZDD at the daily dose of 1 g/kg by gastrogavage. Rats in the azithromycin group were administered with azithromycin suspension at the daily dose of 0. 105 mg/kg by gastrogavage. Equal volume of normal saline was administered to rats in the normal control group and the model group. All medication was performed once daily for 21 successive days. Testes and epididymis were extracted after rats were killed and UU positive rates were compared among all groups. Sperm cells were separated using a mechanical separation technique. Sperm motility parameters were detected using color sperm motion detection system. mRNA and protein expressions of TRPV1 and TRPV5 in spermatogenic cells were determined by real-time quantitative PCR and Western blot.

RESULTSThe UU positive rate was obviously higher in the model group than in the normal control group [(86.7% (13/15 cases) vs. 0] P < 0.05). It was lower in the ZDD group [33.3% (5/15 cases)] and the azithromycin group [26.7% (4/15 cases)] than in the model group (P < 0.05). Compared with the normal control group, class A and B sperms were reduced, the linear velocity and the average velocity were significantly lowered, mRNA and protein expressions of TRPV1 and TRPV5 in spermated genic cells significantly decreased in the model group (P < 0.05). Compared with the model group, class A and B sperms were increased, linear and curve velocities and the average velocity were significantly elevated, mRNA and protein expressions of TRPV1 and TRPV5 significantly increased in the ZDD group and the azithromycin group (P < 0.05, P < 0.01). Compared with azithromycin group, class A and B sperms were increased, the linear velocity and the average velocity were significantly elevated, mRNA and protein expressions of TRPV1 and TRPV5 significantly increased in the ZDD group (P < 0.05, P < 0.01).

CONCLUSIONZDD could fight against UU infection and elevate semen quality, which might be associated with up-regulating mRNA and protein expressions of TRPV1 and TRPV5 in spermatogenic cells.

Objective To develop simple theories and methods for health quality evaluation in moderately prosperous society, and to establish a health quality index (HQI) model to assess the improvement in health quality. Methods Four health quality - related indexes were selected following screening. HQI was then calculated. In 5 provinces, empirical analysis of HQI was conducted. Results In F test, there was significant difference in HQI between different regions of China in 2005. Conclusions The study provides a scientific, comprehensive, sensitive, and intuitive evaluation index, HQI, which may be helpful in assessing the health level.

Objective To investigate the correlation between QRS amplitudes and left ventricular wall thickness in autopsy specimens of elderly men.Methods The data of autopsy cases in our hospital since 1990 were retrospectively analyzed.The cases with QRS duration≥0.12 s and the pacing electrocardiogram were excluded.QRS amplitudes of standard 12-lead electrocardiography in 3 months before death were measured and the correlation between QRS amplitudes and left ventricular wall thickness was analyzed in the elderly men.Results Correlations were found between the amplitudes of the R waves in leads V5 ,V6, Ⅰ ,aVL[(1.1±0.7) mV, (0.95±0.6) mV, (0.44±0.3)mV and(0.35±0.3)mV] and left ventricular wall thickness[(13.6±5.4)mm;r=0.22,0.14,0.22,0.23,all P<0.05], and between the combination of QRS amplitudes SV1 +RV5 or RV6(1.9±1.2) mV] and left ventrieular wall thickness [(13.8± 5.4) mm; r = 0.23, P < 0.05].The correlationbetween the combination of QRS amplitudes (SV1 + RV5 or RV6 ) and left ventricular wall thickness was the strongest in 60-79 years old cases (r=0.48, P<0.01) ,and was decreased in 80-89 years old cases (r= 0.23, P<0.05).There was no correlation between the combination of QRS amplitudes (SV1+RV5or RV6) and left ventricular wall thickness in 90-101 years old cases (r= 0.03, P> 0.05).Conclusions Electrocardiogram is a reliable method for diagnosis of left ventricular hypertrophy in elderly men aged < 90 years.

A 2,4 -dichlorophenol degrading Pseudomonas strain GI241-1 was isolated from a soil sample. The dienelactone hydrolase gene, designated as dcpD which encodes dienelactone hydrolase involved in transforming cis-2-chloro-dienelactone into 2-chloromaleylacetic acid, was cloned from this bacterium strain. The gene cloning strategy was to construct genomic library after location of its neighbouring gene by Southem blot and to screen the aim transformant by dot blotting. Sequencing results showed that length of dcpD is 702bp. The sequence of dcpD and the deduced amino acid are different from the relative sequences registered in the GenBank.

Halomonas sp.BYS-1 was a moderately halophilic bacteria strain isolated from activated sludge,It could grow on MM with NaCl concentration from 0.1～2.6 mol/L and phenyl acetic acid as sole carbon souce. When BYS-1 grew in the media with different concentrations of NaCl, there was no obvious change in its intracellular Na+ contents , it accumulated K+, glutamic acid and betaine as osmoprotectants. Its intracellular contents of K+,glutamic acid and betaine increased by 1.9,2.4 and 13.6 times, respectively, when the concentration of NaCl increased from 0.1 mol/L to 2mol/L.
