Objective To observe the serum B-type natriuretic peptide(BNP)changes in patients with acute coronary syndrome during percutaneous coronary intervention(PCI).Method The serum BNP level was determined and the heart function was assessed in 236 consecutive patients with acute coronary syndrome(ACS) admitted to CCU and in 54 normal normal suvjects as control from January 2005 to December 2006 in Tongji Hospital.The ACS patients were further divided into various subgroups according to the involved arteries and performance of PCI.Serum BNP,hypersensitive c respose protein(HsCRP)level,amd heart comstitution and function were analyzed.Results The serum BNP and HsCRP level were significantly increased in patients with ACS [(332.06?483.17)ng/L and(31.06?52.15)mg/L]more than those in normal subjects [(81.44?195.55)ng/L and(11.15?20.78)mg/L,respectively,P

In the present paper, we measured DNA content of uninuclear Plasrnodium berghei traced with DAPI by means of fluoromi-crospectrophotmeter. The results indicate that the DNA replication of parasite was continuous and it's content was high polyploidy and phase G1 of proliferating cycle was not evident. The dispersion degree of distribution of DNA content in P. R. was markedly lower and the peak sitewas more concentrated and obviously shifted to the right compared with P. N. It was suggested that the speed of DNA replication and proliferating vitality of parasites after producing resistance to SA markedly decreased, indicating that the changes of proliferating kinetics of P. R. happened.

To simulate intervention measures in controlling an outbreak of acute hemorrhagic conjunctivitis on one school campus by using the Susceptible-Infected-Recovered (SIR) model, to provide evidence for preparedness and response to the epidemic. Classical SIR model was used to model the epidemic. Malthusian exponential decline method was employed to estimate the infective coefficient β for interventions. The initial value of parameters was determined based on empirical data. The modeling was implemented using Matlab 7.1 software. Without interventions, the outbreak was expected to experience three phrases: (1)early stage (the first 5 days) in which the epidemic developed slowly and could be intervened easily; (2) rapid growing stage (6-15 days) in which the number of infected cases increased quickly and the epidemic could not be well controlled;and (3) medium and late stage (16 days and later) in which more than 90% of the susceptible persons were infected but the intervention measures failed to prevent the epidemic. With the implementation of interventions, the epidemic was predicted to be controlled in the early stage, under the SIR model. The simulation based on the SIR model kept an acceptable consistency with the actual development of epidemic after the implementation of intervention measures. The SIR model seemed effective in modeling interventions to the epidemic of acute hemorrhagic conjunctivitis in the schools.

Objective To understand the prevailing status of coal-burning endemic fluorosis in Henan, and to provide scientific grounds for endemic fluorosis prevention. Methods Undertook general surveillance on factors such as coal using, living habit, main foods, the structure of the houses and the fluoride content in drinking-water among 1832 historical coal-burning endemic fluorosis villages within 13 counties in 2006 and 2007, and conducted focal point sampling survey on 216 villages which still using local high-fluoride. For all children aged 8-12 years of each village, conducted dental fluorosis examination and collected 30 immediate urinary samples for fluoride content determination. Results The fluoride content in drinking-water of all historical fluorosis villages was below 1.0 mg/L. Households having individual kitchens accounted for 93.7%(241 281/257 393), those with stoves having smoke evacuation devices accounted for 41.9% (107 917/257 393), those using local high-fluoride coal for cooking accounted for 28.6%(73 686/257 393), those using local high-fluoride coal for heating accounted for 24.1%(61 924/257 393). Villages with serf-supply of main foods accounted for 95.7%(1753/1832) of all fluorosis villages. Solar drying food was used in all households. Villages with dental fluorosis detection rate for children aged 8 to 12 years above 30.0% accounted for 16.2%(35/216), which axe all in Luoyang City. Among 77.8%(168/216) of fluorosis villages, children' s urinary fluoride concentrations were no higher than 1.50 mg/L. Conclusions Coal-burning endemic fluorosis areas in Henan Province were decreased greatly and the extent of the health hazard was becoming slightly. The detection rate of dental fluorosis for children aged 8 to 12 years of 8 counties had reached the standard for fluorosis control, whereas the other 5 counties had not yet, all located in Luoyang City.

OBJECTIVETo establish the diagnosis evidence of objective tongue inspection for liver cancer (LC) patients with damp-heat syndrome (DHS) by dynamically observing their tongue figures using modern tongue image analytic apparatus, and to explore the effect of intervention on the tongue figures.

METHODSTongue figures were collected from 142 LC patients with DHS by tongue image analytic apparatus. Red (R), green (G) and blue (B) values were analyzed. The r and g values were calculated requesting r=R/(R+G+B), g=G/(R+G+B), and b=1-r-g, and scored in combination with Chinese medical symptoms scale. The tongue figure and correlated scores were collected from 59 of them 3 days after transcatheter arterial chemoembolization intervention.

RESULTSThe range of objective tongue inspection of LC patients with DHS was as follows: as for tongue fur, 0.360

CONCLUSIONThe range of objective tongue inspection of LC patients with DHS could be known by collecting and analyzing objective indicator of tongue figures, thus laying foundation for further studies with analysis of correlation between intervention and Chinese medicine based on tongue figures.

Structure of natural product-ursolic acid was modified for increasing its antitumor activity. Ursolic acid was acylated, esterified, hydrolized or oxidized to obtain target pentacyclic triterpenoid compounds with different substitutes. Sixteen derivatives of ursolic acid were designed and synthesized including eleven new compounds. Anti-tumor activities of ursolic acid and these derivatives against HeLa, SKOV3 and BGC-823 cells in vitro were investigated by MTT assay. The results indicated that compounds 7a and 8a were found to have stronger cell growth inhibitory than ursolic acid on HeLa cells and SKOV3 cells separately, and are worth to be intensively studied further.

Green fluorescent protein (GFP) gene was inserted into the pseudogene (psi) region of genome of rabies virus rHep-Flury strain, and a recombinant rabies virus carrying GFP, designated as HEP-GFP, was rescued by reverse genetics system. It was demonstrated that green fluorescent protein could be expressed in the chimeric virus after 5 passages in BHK-21 cell line. The research indicated that the pseudogene (psi) region in the genome of rHEP-Flury strain, as an independent functional unit in the process of virus assembly, could independently carry and express exogenous genes.

OBJECTIVETo explore a treatment program for increasing therapeutic effect on rheumatoid arthritis at active stage.

METHODSOne hundred and forty-six cases were randomly divided into treatment group (n = 74) and medicine control group (n = 72). The treatment group were treated by electroacupuncture at Quchi (LI 11), Hegu (LI 4), Yanglingquan (GB 34), etc. , combined with meloxicam, sulfasalazine and MTX. The control group treated by simple the Western medicines. Their therapeutic effects were compared.

RESULTSThe effective rate was 79.73% in the treatment group and 51.39% in the control group with a significant difference between the two groups (P< 0. 05).

CONCLUSIONElectroacupuncture combined with medicine has a better therapeutic effect than the simple medicine on rheumatoid arthritis at active stage.
