Thelper 17 ( Th17 ) cells and regulatory T (Treg) cells are resistant to each other in their functions and differentiation pathways.Th17 cells and Treg cells play different roles in the development,treatment and prognosis of leukemia.Their functions are stronger and(or) numbers are more increasing than in the healthy controls.Th17 cells mainly function to promote inflammation and improve the body's defense capability to leukemic cells.Treg cells mainly mediate immune suppression and immune tolerance,and then inhibit the body's immune response to leukemia cells,which can results in poor treatment outcomes.Both Th17 cells and Treg cells have close relationships with the development,treatment and prognosis of leukemia.We would deal with the leukemia through the intervention of naive T cell differentiation.

Objective The purpose of this study was to investigate the effects of a breast cancer screening educational program on women's knowledge and intention to seek breast cancer screening in China.Methods 60 patients were divided into the experimental group (30 cases) and the control group (32 cases).The experimental group received breast cancer screening educational program,while the control group did not.A pre-test and post-test were used in both the experimental and the control groups.A convenience sampling was used.Two structured questionnaires were used.Results The mean scores of knowledge of breast cancer screening and intention to seek breast cancer screening of the experimental group were statistically different from those of the control group after the education.Statistical difference also existed in the experimental group in the above aspects within the experimental group.Conclusions Application of breast cancer screening educational program can improve women's knowledge and intention to seek breast cancer screening,as well as supply reference for prevention item of breast cancer.

As a member of homeobox gene family,HOXA5 is expressed in many organs and can regulate gene expression,cell differentiation and morphogenesis.Its structure and (or) function abnormalities are closely related to the development of leukemia,breast cancer,brain hemangioma,hepatocellular carcinoma and so on.Researching the relationships between HOXA5 and tumors contributes to cancer diagnosis,treatment and prevention.

BACKGROUND:Light-cured resin is a new kind of material with beautiful color, high strength, wide range of applications, easy-to-use and inexpensive features. Patients are wil ing to accept it because of less or no grinding of the teeth.
OBJECTIVE:To observe the effect of light-cured resin to fil the interdental space between maxil ary anterior teeth.
METHODS:A total of 32 patients aged 21-52 years were enrol ed, 107 teeth with 75 oversized maxil ary spaces, including 15 males and 17 females. One space between bilateral central incisors was found in 14 cases;three spaces between bilateral central incisors, left lateral incisor, and left canine were found in three cases;three spaces between bilateral central incisors, right lateral incisor, and right canine were found in two cases;four spaces between left central incisor, left lateral incisor, left canine, right central incisor, and right lateral incisor were found in three cases;three spaces between bilateral central incisors and lateral incisors were found in six cases;four spaces between left central incisor, left lateral incisor, right central incisor, right lateral incisor, and right canine were found in four cases. Al the oversized maxil ary spaces were fil ed with light-cured resin. Then, crown morphology, adaptation, color, degree of wear and loosening were observed during fol ow-up.
RESULTS AND CONCLUSION:After 3-year fol ow-up, 17 of 32 cases were successful in tooth repair:the crown morphology and tooth adaptation were good, and there was no prosthesis loosening or detachment and discoloration. The tooth space was repaired basical y in another nine cases:the crown morphology and tooth adaptation were not good enough, no prosthesis loosening or detachment was found, but there were some defects at the gingival margin and contact surface of teeth as wel as mild discoloration. Tooth repair failed in the other six cases with worse crown morphology and adaptation, prosthesis loosening or detachment, and severe discoloration, which need to be repaired again.

Six taxane diterpenoids were isolated from the stem bark of Tax us cuspidata Sieb. et Zucc.. On the basis of physical and chemical properties and spectra analysis,they were identified as 2'-de sacetoxyaustrospicatine(Ⅰ). taxol(Ⅱ),cephalomannine (Ⅲ), 2-deacetoxyl taxinine J (Ⅳ),taxinine B(Ⅴ) and 10-deacetyl-7-0-?-Dxylosyl-taxol (Ⅵ).

Objective To explore the effect of scalp acupuncture combined with rehabilitation on acute cerebral infarction patient's movement disturbance synchronously.Methods Fugl-Meyer Assessment was used to assess the motor function of scalp acupuncture combined with rehabilitation synchronously and non synchronously.Results The motor function of the group for scalp acupuncture combined with rehabilitation synchronously was improved prominently and was superior to control group on the 20th day and 30 day of the period of treatment.Conclusion The therapy of scalp acupuncture combined with rehabilitation synchronously and non synchronously can all improve the patient's motor function obviously,and the effect can increase with prolong of the period of treatment in a certain period. The advantage of the two Methods being used synchronously was appread and increased gradurally with prolong of the period of treatment and the therapy is worthy of being generalized.

Objective To determine impacts of p53 with R213 mutation on the expression of its downstream target gene p21 in HCT116-/-colorectal cancer cell line.Methods Mutations of p53 at R213Q (R/Q) and R213K (R/K) were respectively constructed and transfected into the p53 null HCT116 cells.The promoter activity drived by p53 was detected by dual-luciferase reporter system.EMSA assay was used to detect the ability of p53 binding to the promoter of its target gene p21.The expression of p53 downstream target genes p21 was examined by real-time PCR and Western blot experiments.Results The mutation of R213K disrupted the efficiency of p53 transactivation(P<0.05).The mutants were less efficient in targeting the consensus binding sequences of p53 in the regulatory region of p21 gene(P<0.05), In addition, The R/K mutant attenuated the expression of p21 gene(P<0.05).The mobility of R213Q was increased.Conclusions The different mutations of Arginine 213 have different impact on p21 in colorectal cancer cells.It could exist diverse regulating mechanisms.

ObjectiveTo identify the status of quality of life in breast cancer patients and explore the impact of environmental factors on quality of life in breast cancer patients receiving chemotherapy. MethodsTotally 201 primary breast cancer patients undergoing chemotherapy after surgery were investigated.Self-developed demographic and clinical character investigation questionnaire,WHO Disability Assessment Schedule Ⅱ(WHODAS Ⅱ),and environmental factors in International Classification of Functioning Disability and Health(ICF)core sets for breast cancer patients were adopted to collect relevant data. ResultsBreast cancer patients had different levels of difficulties on each domain of WHODAS Ⅱ.Multiple stepwise regression analysis demonstrated that“material and emotional support and interrelationship with friends”, “social security service,system and policies” and“social norms,practices and ideologies” were factors influencing quality of life of breast cancer patients. ConclusionsIn addition to the strengthen of rehabilitation exercise training,nurses should advocate more services from society through policy making,prompt public awareness and scientific cognition,as well as construct effective nursing interventions to help enlarge social support resources and improve social support level.

Objective To evaluate the recent impact and long-term effects of recombinant human acidic fibroblast growth factor (rh-aFGF) of cesarean section on women's abdominal incision healing.Methods In 516 cases of cesarean section in women,randomly divided into placebo group (172 cases),spray group (172 cases) and flush group (172 cases).The placebo group received 0.9％ sodium chloride washing abdominal incision suture.The spray group incision suture direcdy after the administration of rh-aFGF spray,per square meter of 3-4 sprays,3-5 times/d.The flush group was given before 2 rh-aFGF dissolved in 10-20 ml of 0.9％ sodium chloride directly after washing the incision suture,then given spray treatment.The recent follow-up of 15 d observed maternal abdominal incision healing.Long term follow-up of 3 months to observe the incision scar formation.Results The abdominal incision heating time was (8.6 ±3.5) d,that was obviously shorter than that in spray group (10.4 ±3.7) d and placebo group (12.7 ± 4.9) d (P ＜ 0.05).The delay healing accounted for 4.2％ (7/166) in flush group,significantly lower than that in placebo group (34/168,20.2％) and spray group (16/165,9.7％) (P＜ 0.05).There was no significant difference in the incidence of fat liquefaction,postoperative infection among three groups (P ＞ 0.05).Flush group exudation,abdominal wall adhesions was lower than placebo group and spray group [2.4％(4/166) vs.10.1％(17/168),5.5％(9/165),3.6％(6/166) vs.17.3％(29/168),9.7％(16/165)](P＜0.05).Long term follow-up,flush group scar area than spray group reduced by 13.5％,than placebo group reduced by 27.2％.Conclusions A recent rh-aFGF can reduce the cesarean section abdominal incision healing time and reduce abdominal wall adhesions and exudation;rh-aFGF the best dosage is intraoperative irrigation treatment spray combined with postoperative.
