OBJECTIVETo evaluate the effects of Yili dark bee propolis on the main cariogenic biofilm and mechanisms.

METHODSSusceptibilities to the ethanolic extract of propolis against Streptococcus mutans (S. mutans), Streptococcus sobrinus (S. sobrinus), Streptococcus sanguis (S. sanguis), Actinomyces viscosus (A. viscosus), and Actinomyces naeslundii (A. naeslundii) were analyzed by crystal violet stain method to determine the minimum biofilm eradication concentration (MBEC). The biofilm was initially cultivated for 24 h. Subsequently, the propolis groups with different concentration MBEC and initial pH 7.0 were cultured for 24 h. Moreover, the pH value was measured to evaluate the acid-producing ability of the tested plaque biofilm. The effects of propolis on the insoluble extracellular polysaccharide synthesis of S. mutans biofilm were evaluated by anthrone method.

RESULTSThe MBEC of Yili propolis on S. mutans, S. sobrinus, S. sanguis, A. viscosus, and A. naeslundii were 6.25, 1.56, 3.13, 0.78, and 0.78 mg.mL-1, respectively. Propolis could decrease the ΔpH of the tested plaque biofilm, and the differences between the control and propolis groups were statistically significant (P<0.05). At MBEC, propolis could reduce the ability of S. mutans in synthesizing insoluble extracellular polysaccharides.

CONCLUSIONYili propolis demonstrate remarkable eradicative effects on the cariogenic plaque biofilm, showing inhibition of the synthesis of biofilm-produced acids and insoluble extracellular polysaccharides.

0.05).At the T1,T3,T4,T7 time point,changes of the MAP and HR were more stable in TCI group than those in control group.The awakening time and extubation time in TCI group was obviously shorter in than that in control group.The OAAS scores after extubation were higher and the VRS scores 30 min after extubation were lower in TCI group than those in control group(P

AIM: To evaluate the changes of serum total prostate specific antigen (T-PSA), free prostate specific antigen (F-PSA) and the ratio of F-PSA to T-PSA (F/T) in patients with prostate cancer (PCa) and its clinical significance. METHODS: The concentrations of T-PSA and F-PSA in serum were measured by micropartical enzyme immunoassay (MEIA) using AxSYM System, and the F/T ratio was calculated. RESULTS: Before operation, the concentrations of T-PSA and F-PSA in patients with PCa were much higher and F/T ratio was significantly lower than that in patients with benign prostate hyperplasia (BPH). T-PSA and F-PSA levels decreased, but F/T ratio increased after operation in PCa and BPH. F/T ratio in 83.5% PCa and 6.5% BPH was less than 0.16. To diagnosis PCa, the sensitivity of F/T ratio was 83.5%, and the specificity was 86.7%. CONCLUSION: Serum T-PSA, F-PSA and F/T ratio are important parameters for the early diagnosis of prostate cancer. [

BackgroundThe study of the molecular mechanism of visual plasticity is helpful for the explaining and prevention of strabismus and amblyopia.The effect and significance of NogoA in the strabismus and amblyopia formation are attracting more attention.ObjectiveThe present study was to investigate the expression of NogoA in 21a area of visual cortex in strabismic-induced amblyopia cats and explore the possible molecular mechanism of strabismic-induced amblyopia.MethodsSixteen 4-week old clean cats were randomizedly divided into normal group and strabismic-induced amblyopia group and eight for each group.The strabismic-induced amblyopia models were created by cutting off the external rectus in 8 cats.Pattern visual evoked potentials ( P-VEP ) were recorded 1 week after operation and compared with normal cats,and depression of amplitude and prolongation of implied time of P100 wave were as the successful criterion of model.The 200 ml paraformaldehyde was infused via heart to fax the brain under the deep anesthesia and then the cats were sacrificed and the brain cortex sections were prepared.The morphology of 21a zone of cat visual cortex was examined by haematoxylin and eosin staining,and the expressions of NogoA in 21a area of visual cortex were detected by immunohistochemistry with a monoclonal antiNogoA antibody.The use of the animals complied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.ResultsThe implied time and amplitude ratio of VEP P100 wave were (98.10±7.07)ms and (0.83±0.14) in normal group,and those in strabismic-induced amblyopia group were (108.50±6.95 )ms and (0.35 ±0.09 ),showing significant differences between two groups (t=4.450,P=0.005 ; t =5.970,P =0.005 ).The numbers of neurons were similar in 21a area of visual cortex between the two groups,but the volume of the neurons was lessen in strabismic-induced amblyopia group.The positive cell densities for NogoA were ( 387.37±2.01 ) cells/mm2,( 354.58± 1.85 ) cells/mm2 and ( 289.68± 1.81 ) cells/mm2 in layer Ⅱ/Ⅲ,Ⅳ and V/V[ respectively in strabismic-induced amblyopia group,and those in normal group were ( 161.39± 1.98 ) cells/mm2,( 128.93 ± 1.26 ) cells/mm2 and ( 96.25 ± 1.49 ) cells/mm2,indicating a significant increase in model cats ( t =- 160.400,- 201.890,- 164.740,P =0.000 ).Conclusions NogoA may play an important role in the regulation of the sensitive developmental period of visual sense and its plasticity.

Background The extraocular muscles (EOMs) Pulley is considered as the functional origins of the recti EOMs,it is determinants of ocular motility.Objective The structure of the connective tissue around EOMs in cat was studied,and the role of EOMs Pulley to ocular movement was investigated.Methods Five adult cats were involved.The gross anatomy of an orbit in each cat was observed.The other orbit was processed with paraffin imbedding and coronal serial sections.A murine monocolonal antibody to α-smooth muscle actin (α-SMA) was used to show smooth muscle,while Masson trichrome stain was used to show muscle and collagen,and Weigert stain to show elastin.Results An encircling ring of collagen circled EOM was thin and connected to the orbital layer of muscle fiber loosely.Less elastin fibers and little smooth muscle cells were embedded in the collagen ring and connective band.Collagen ring around medial rectus and the connective band between medial rectus and inferior rectus was not more significantly developed than other bands.Conclusions The connective tissue around EOMs in cat may be related to its function of ocular movement,which is not developed.

Objective To study the expression and clinical significance of CD34 and smooth muscle actin (SMA) in stroma of breast tissues and lesions. Methods Seventy cases of breast tissues and lesions, including 20 fibroadenomas, 10 sclerosing adnoses, 30 invasive ductal carcinomas and 10 invasive lobular carcinomas were investigated, and 10 normal breast tissues were served as controls. Immunohistochemical staining was applied to compare the distribution of CD34+ fibrocytes and SMA-reactive myofibroblasts. Results The stroma of normal breast tissue contained CD34+ fibrocytes, whereas SMA-reactive myofibroblasts were absent (100% for both). All benign breast lesions exhibited astromal CD34+ fibrobytes, and fibroadenomas showed SMA-reactive myofibroblasts as well. In invasive ductal and lobular carcinoma the stroma was devoid of CD34+ fibrocytes, but a varying number of stromal SMA-reactive myofibroblasts were detectable (100%). Conclusion In breast carcer, immunohistochemical staining used in detecting expressions of CD34 and SMA is helpful in distinguishing benign lesions from malignancies.

Objective Lactate dehydrogenase (LDH) is shown to be an important virulence factor resulting in acid production of Streptococcus mutans(S.mutans), on which the cariogenic potential of S.mutans depends.Differences in cariogenic abilities of S.mutans isolates may be determined by genetic heterogeneity from virulent factors.The relationship between enclosed Uyghur children LDH activity or genetic diversity and cariogenicity of S.mutans(serotype c)isolates was studied in this research.MethodsChoose 6 original inhabitants of the countryside from the age of 3 to 5 years old closed Uighur children in kashika.These isolates came from 35 caries-active individuals and 37 caries-free enclosed Uyghur ones, in which 27 strains showed the high LDH activity and 24 strains showed the low LDH activity.Then genetic diversity of PCR products were analyzed or assessed by restriction fragment-length polymorphism(RFLP).Some of amplified LDH genes from different group were sequenced and assayed.ResultsIt is testified that two genotypes A and B of ldh-RFLP were revealed when LDH genes were digested with MseI,but MnlI,DdeI,NlaⅡI and AluI digesting fragments of ldh gene did not show different pattern.Furthermore,Fisher Exact one-Tail Test showed that the proportion of Genotype B strains from caries-active individuals was higher than that from caries-free ones(P<0.05),while the distribution genotypes A,B with different LDH activity was different between two groups(P<0.05),high proportion of the LDH active group genotype B strains than the low activity group.ConclusionThis study indicated that LDH gene of S.mutans strains from Enclosed Uyghur children different individuals is conservative, while there still is the gene mutation in.The ldh genetic diversity may be related to the high caries sensitivity, and closely correlated with the differences in LDH enzyme activity of S.mutansstrains.
