The present article introduces a cardiopulmonary resuscitation model haif- length above the cross-section at the level of sixth rib.It wad designed on the basis of normal human antomy with lifelike configuration of heart,lungs,and some other organs.Synchronous pulsation of carotid artery could be detected during extracorporal cardiac massage,The accuracy of massage technique could be displayed by red and green coloured bulbs.A ninety-degree overextension of the neck is maintained during artificial respiration.Its function allows expansion of both the thorax and the lungs,lt is suitable for teaching in medical university and college and trining of first-aid personnel.

OBJECTIVE: To observe the effects of recipe for invigorating kidney on expression of estrogen receptors in ovariectomized rats. METHODS: The rats, which were given high-cholesterol diet after ovariectomy, were chosen as experimental subjects. After fed kidney-invigorating recipe for 16 weeks, the rats were killed and the levels of serum lipid and estradiol of these rats were examined. The expressions of estrogen receptor alpha and beta mRNAs in aorta, pituitary gland and hypothalamus, and the affinity of estrogen receptor-ligand were also detected. RESULTS: The kidney-invigorating recipe could increase the expression levels of estrogen receptor alpha and beta mRNAs in different parts such as aorta, pituitary gland and hypothalamus, and enhance the affinity of estrogen receptor-ligands. CONCLUSION: The recipe for invigorating kidney may meliorate atherosclerosis in ovariectomized rats by regulating the estrogen receptors.

Objective To explore the association between gene polymorphism of interleukin(IL)-4 C590T and serum level of IL-4 and atherothrombotic cerebral infarction(ATCI).Methods The gene polymorphisms of IL-4 C590T in 159 patients with ATCI and 151 normal control subjects were carried out by polymerase chain reaction(PCR)-restriction fragment length polymorphism(RFLP).The serum level of IL-4 in normal control group was determined with enzyme linked immunosorbent assay(ELISA) method.Results In the normal control group,the serum level of IL-4 in TT genotype[(31.85?5.68) pg/ml] was higher significantly than those in TC[(28.67?6.00) pg/ml] and CC genotypes[(20.98?0.99) pg/ml],TC genotype was higher significantly than CC genotype(all P0.05).Conclusions IL-4 590T allele is associated with higher level of serum IL-4.The C590T polymorphism is not associated with the incidence of ATCI.

Objective: To study the effectiveness of anti-tumorgenecity of human IL-10 antisense and viral IL-10 antisense on nasopharyn-geal carcinoma(NPC) cells.Methods:Human IL-10 cDNA and viral IL-10 gene had been amplifed and cloned. A two-valent eukaryotic expression vector for antisense nucleic acids of human IL-10 cDNA and viral IL-10 gene had been constructed and designated as pcDNA3/AS hIL-10 + AS vIL-10.The recombinant vector was transfected into a NPC-clerived cell strain-SUNE cells. After that, the transfected and nontransfected SUNE cells were inoculated i.d. in the right flank of SCID mice and hu-PBL-SCID mice to evaluate their tumorgenecity changes.Results:The results of ELISA analysis showed that the concentration of hIL-10 and vIL-10 was 242 ?3 pg'ml-1 in supernatant of the nontransfected SUNE cells, and onry 22 ? pg ?ml-1 of hIL-10 and vIL-10 contained in supernatant of the transfected SUNE cells. After inoculation to SCID mice, the transfected and nontransfected SUNE cell showed the same growth manner. But inoculating to hu-PBL-SCID mice, the transfected SUNE cells grew slowerly than the nontransfected SUNE cell. With statistical analysis, the size and mean weight of the tumors from the hu-PBL-SCID mice inoculated with transfected SUNE cells were significantly lower in contrast to that from the hu-PBL-SCID mice inoculated with nontransfected SUNE cells( P

Objective:To investigate the epitope and its immunogenicity of bFGF. Methods -.The phage disply 7 peptides library was screened with monoclonal antibody GE22 to bFGF, which neutralize the bioactivin'es of bFGF. Results: After three cycles screening, the isolated phage clones with GF22 epitopes specifically inhibited bFGF binding to GF22.Sequence analysis showd that the epitopes shared a highly consensus spequence( Leu-Pro-Pro/Leu-Gly-His-Phe/He-Lys) and PPGHFK sequence was located at aino acids 22-27 (PPGHFK) within bFGF (155aa) molecule.Phage clones with the epitopes could highly induce imuno-response in mice,eapically with the sequence LPLGHK was 3 times higher than original sequence. Conclusion:Trie sequence LPLGHK may be a valuable vaccine in future studies of bFGF.

Lung adenocarcinoma is usually thought to follow a linear multistep progression schema,that is precancerous lesions progress to adenocarcinoma in situ,and progress to micro-invasive adenocarcinoma,eventually some lung adenocarcinoma happen diffusion.However,recent findings reveal that this linear progression schema might not occur in all lung adenocarcinoma subtypes,and some subtypes show a kind of non-linear progression schema.The study of these two kinds of schemas can help for early detection of lung adenocarcinoma.

OBJECTIVE:To observe the clinical efficacy of herbal desensitizer in the treatment of dentine hypersensitivity. METHODS: 126 patients with dentine hypersensitivity were enrolled: 64(a total of 172 diseased teeth) were randomly assigned to trial group to be treated with herbal desensitizer,and 62(158 diseased teeth) to control group to be treated with sodium fluoride glycerin. The clinical effects observation was scheduled immediately,3 and 6 months after the treatment. Then the results were analyzed using statistics software.RESULTS: Significant differences were found between the trial group and the control group in clinical effects (P

OBJECTIVE:To introduce the Fair PharmaCare program of BC Canada for the reference of the reform of China's medical insurance system.METHODS:The running procedure of Fair PharmaCare program of BC Canada was introduced in detail and its characteristics were analyzed.RESULTS & CONCLUSIONS:Fair PharmaCare program covers all BC residents and protects them against economic difficulties in pharmacare.The program serves as a reference for the reform of China's medical insurance system.

Medical morality,especially dental ethical account is usually demonstrated by ethical theories,including theory of utilitarianism,deontology,and virtue ethics.In fact,the true purpose of medical education is to produce erudite and humane practitioners and medical researchers.The present study discussed the efficacy of dental ethical educations through clinical practical issues.
