With more and more attention and investment on acupuncture scientific researches, considerable outcomes and achievements has been acquired, but the shortcoming of low transformation rate of acupuncture research achievements is gradually exposed. Nowadays there is no related report on this problem, so based on achievement translational research in other areas and practical situation of acupuncture, the existing problems and solutions are analyzed. As a result, the existing problems include (1) the research content is mainly basic research and clinical research but less acupuncture device research, leading to limited transformation efficiency; (2) the evaluation system and transformation pattern are still needed to be perfect. The solutions are (1) to properly evaluate the research achievements of acupuncture, (2) to advocate the concept and method of translational medicine, (3) to reform the policy and system, and (4) to establish valid platforms covering research, outcomes and transformation.

Chinese medicine pair (CMP) was frequently applied in traditional Chinese medicine (TCM) clinic, and its significance was shown in long-term clinical practices and many accumulated experiences. It is the unique combination of two relatively fixed Chinese medicines in TCM clinic with the basic feature and principle of TCM compatibility, is the most fundamental and the simplest form of TCM formulae with certain theory basis and combinatory reason, which is proven effective. And the unique combination is frequently used for achieving mutual reinforcement or detoxication. CMP is an intermediate point between single herb and many TCM formulae, reflecting the regularity of TCM formulae compatibility and connotation of differential treatment. This paper analyzed and summarized the basic characteristics, development process and research significance of CMP, which aims to lead the modern basic and applied research on compatibility theory of CMP.

OBJECTIVETo assess the efficacy of ultrasonic irrigation of the root canal in vivo and in vitro.

METHODSSixty anterior teeth or premolars with the diagnosis of periapical periodontitis were divided into two groups (syringe irrigation group, group S and ultrasonic irrigation group, group U) and were evaluated clinically. Sixty extracted teeth with single straight canals were selected. Forty of them were divided into two groups and were evaluated histologically. Another twenty teeth were divided into two groups and were evaluated by SEM.

RESULTSClinically, the number of lateral canals obturated in group U was more than that in group S (P < 0.01). The incidence of pain during irrigation were 13.3% in group S, and 3.3% in group U (P > 0.05). Histologically, the amount of organic debris of the root canals in group U were significantly less than that in group S (P < 0.01). By SEM study, the number of visible open dentinal tubules in group U were significantly greater than that in group S (P < 0.05).

CONCLUSIONUltrasonic irrigation of the root canal will be a useful technique in root canal therapy.

OBJECTIVETo examine the expressions of HLA class I antigen and CD8 in various cervical diseases and investigate their association with cervical cancer.

METHODSThe expressions of HLA class I antigen and CD8 in cervical tissues sampled from patients with cervical cancer, cervical intraepithelial neoplasia (CIN), and chronic cervicitis were detected using SP immunohistochemistry. The association of the expressions of HLA class I antigen and CD8 with the clinicopathologic indices of the patients was analyzed.

RESULTSThe positive expression rates of HLA class I antigen in cervical cancer, CIN, and chronic cervicitis were 22.6%, 100.0%, and 100.0%, and the positive expression rates of CD8 were 22.6%, 95.5%, and 100.0%, respectively. The positive rates of HLA class I antigen and CD8 were significantly lower in patients with cervical cancer (P<0.01). Patients with stage I cervical cancer had significantly higher positive rates of HLA class I antigen and CD8 than those with stage II cervical cancer (46.7% vs 0.0%, 46.7% vs 0.0%, both P<0.01). The expressions of HLA class I antigen and CD8 decreased with the progression of the clinicopathological stages, and may even become undetectable. The expressions of HLA class I antigen and CD8 were not related to the differentiation degree of the tumor or lymph node metastasis (P>0.05). A positive correlation was found between HLA class I antigen expression and CD8 expression.

CONCLUSIONThe expressions of HLA class I antigen and CD8 are down-regulated or deleted in CIN and cervical cancer, and they may play important roles in the development and progression of CIN and cervical cancer.

OBJECTIVETo explore the biomarkers of manganese exposure by measuring the manganese (Mn) and iron (Fe) level as well as the mRNA change of Hepcidin, divalent metal-ion transporter-1 (DMT1) and Parkin-2, one of genes related to Parkinson disease in body fluid and brain tissues of rat.

METHODSMale Sprague-Dawley rats were administered (i.p) either MnCl2 solution (6 mg Mn/kg) or the same volume saline, 5 times per week and for 4 weeks. Graphic furnace Atom Absorption Spectrum (AAS) was applied to measure the concentration of Mn and Fe in brain tissue and body fluids. Meanwhile Hepcidin, DMT1 and Parkin-2 mRNA expression were detected by real-time RT-PCR.

RESULTSMn concentration in erythrocytes of rats was the 86.9 folds of that in control; No significant change was found in plasma. However the trend and range of Mn increase in cerebrospinal fluid (CSF) was the same as that in brain tissue including striatum, cortex, hippocampus and choroid plexus. Meanwhile Fe concentration in brain tissue of Mn exposed rats was also higher than that of control, whose trend was as same as that in CSF. However iron concentration in plasma decreased. The real-time RT-PCR data also showed that Hepcidin mRNA expression in Mn-exposed rat decreased 56% in blood, which was in line with its expression in cortex(67%). Similarly, Parkin-2 mRNA expression decreased both in blood (42%) and in striatum. However DMT1 mRNA expression increase 38% in striatum of Mn-exposed rats but decreased in blood.

CONCLUSIONHepcidin and Parkin-2 mRNA expression in blood might be serves as the effective biomarkers following manganese exposure, certainly which needs to be further explored.

BACKGROUND: Although a large number of related studies have been carried out, there is still a lack of practical methods to amplify hematopoietic stem cells(HSCs)in vitro.Mesenchymal stem cells(MSCs)secrete a variety of cytokines that promote the HSCs proliferation and inhibit their differentiation. These cytokines play an important role in maintaining the hematopoietic microenvironment and regulating HSCs function. OBJECTIVE:To investigate the effect of bone marrow MSCs on the proliferation of HSCs in vitro under different coculture modes. METHODS:Mesenchymal stem cells from the bone marrow of C57BL/6 mice were cultured in vitro using the whole bone marrow adherent culture. CD117+cells (HSCs) were sorted from passage 3 cells by using miniMACS magnetic beads sorting. Then, CD117+cells were co-cultured with MSCs under different coculture models, including single culture of HSCs (control group), Transwell coculture (upper chamber, HSCs; lower chamber, MSCs) and two-dimensional contact coculture (coculturing HSCs and MSCs in 24-well plates). The morphology of HSCs was observed under phase contrast microscope and fluorescence microscope, and the number of active cells of HSCs was counted at 1, 3, 5, and 7 days after coculture. RESULTS AND CONCLUSION: During the coculture of 1-7 days, the number of HSCs in the two groups was increased with culture time (P <0.05). After 3 days of coculture, HSCs in each group was grown into the logarithmic growth phase, and morphological changes in some HSCs were detected at 5 days of coculture. At 7 days of coculture, the viabilities of HSCs in different culture models were ranked as follows: single culture model < Transwell coculture model < two-dimensional contact coculture model (P < 0.05). These findings suggest that MSCs can effectively promote the proliferation of HSCs in vitro,and the promotion effect is increased under contact coculture conditions.

OBJECTIVETo study the clinical characteristics and outcomes of BCR/ABL-positive acute lymphoblastic leukemia (BCR/ABL360888725-ALL) and screen the prognostic factors for BCR/ABL360888725-ALL.

METHODSFrom January 2001 to May 2008, 59 patients (median age of 32 years ranging from 3 to 69 years) with the diagnosis of BCR/ABL360888725-ALL by fluorescence in situ hybridization received induction chemotherapy with VDLP-/+Ara-C regimen. The patients who failed to respond to the chemotherapy received subsequent consolidation chemotherapy with imatinib (400-800 mg/day) (17 cases) or allogeneic hematopoietic stem cell transplantation (allo-HSCT) (16 cases).

RESULTSOf the 59 patients, 32 (58.3%) achieved complete remission (CR) after the first induction cycle. In patients with peripheral white blood cell (WBC) count <30=10(9)/L, 30-99.9(9)/L and > or =100(9)/L, the CR rates were 75.0% (18/24), 56.3% (9/15) and 26.3% (5/19) (P=0.006), and the overall survival probability of 2 years ( OSs of 2-yrs) was 24.7%, 22.5% and 21.1%, respectively (P=0.180). According to the FAB classification, 56 cases were divided into L1, L2 and biphenotypic acute leukemia (BAL) subgroups, and their CR rates were 66.7% (6/9), 63.2% (24/38) and 22.2% (2/9) (P=0.029), with OSs of 2-yrs of 22.2%, 27.0% and 22.0%, respectively (P=0.623). In terms of immunophenotype grouping by EGIL, the patients with ALL, myeloid antigen-positive ALL and BAL had CR rates of 61.1% (11/18), 60.6% (20/33) and 12.5% (1/8) (P=0.039), and the OSs of 2-yrs of 22.7%, 21.0% and 18.8%, respectively (P=0.643). In 55 patients with known karyotype, the CR rates were 71.4%(5/7), 70.8% (17/24) and 37.5% (9/24) in normal, sole t(9;22) abnormality, t(9;22) with additional abnormalities groups (P=0.046), with the OSs of 2-yrs of 42.9%, 34.0% and 7.3%, respectively (P=0.000). The patients complicated by septicemia had significantly lower OSs of 2-yrs than those without septicemia (0% vs 38.8%, P=0.005). The OSs of 2-yrs were significantly higher in patients with consolidation chemotherapy with imatinib than those without (48.0% vs 11.2%, P=0.001), and allo-HSCT was associated with significantly higher OSs of 2-yrs than exclusive chemotherapy (54.2% and 8.5%, P=0.000).

CONCLUSIONBCR/ABL360888725-ALL with WBC> or =100 x 10(9)/L, presence of BAL diagnosed by FAB or FACM, t(9;22) with additional chromosome abnormalities all adversely affect the treatment results, and additional chromosome abnormalities and septicemia are associated with lower OSs of 2-yrs. Imatinib treatment and allo-HSCT can both improve the OSs of 2-yrs of the patients with BCR/ABL(+)-ALL.
