Objective: The primary aim of this research is to systematically sort out and analyze available documents for yang deficiency syndrome in traditional Chinese medicine, providing innovative ideas and methods for statistical study of yang deficiency syndrome. Methods: Based on the China National Knowledge Internet (CNKI) and Chongqing VIP databases, using "yang deficiency", "deficiency cold", and "patient" as keywords, we searched literature of clinical researches and used "ratio-comparison" and "integration-comparison" to analyze objective data after data preprocessing. Relative importance value of physiological and biochemical parameters were reflected by P value calculated by ratio-comparison or Q value by integration-comparison. Results: With calculation of relative importance values of clinical indicators among various systems, we got the ranking of relative importance of different indexes. Triiodothyronine and urine 17-hydorxycorticosteroid of endocrine system, immunoglobulin A of immune system, and the ratio of cyclic adenosine monophosphate to cyclic guanosine monophosphate, which had great |P| (or |Q|) values and negative P (or Q) values, had a clearly lower level in yang deficiency patients than in the control; hemorheological indicators such as plasma viscosity, whole blood reduced viscosity and erythrocyte electrophoresis time had small |P| (or |Q|) values. These indicators, however, showed less importance for reflecting yang deficiency. Conclusion: Ratio-comparison method and integration-comparison method employed in this study have merits of efficiency and robustness. After detailed compiling and mining of all available data, we have made reasonable advice on the most relevant index of yang deficiency for further study of the essence of this syndrome.

ObjectiveTo understand the urban preference for outpatient pre-registration in large hospitals,and probe into the influencing factors,for recommendations to improve outpatient preregistration at the hospitals.Methods With Nanjing City as an example,the authors used tailoreddesigned questionnaire and qualitative interviews to investigate the preference of 1200 households of local residents regarding outpatient clinical pre-registration service at the tertiary hospitals.Results Age,education and economic factors are found to be the most important influential ones for urban preference in their outpatient pre-registration at large hospitals.Other factors include traditional approaches to outpatient clinic,inconvenience for outpatient pre-registration,and concerns for appointment breaking.Conclusion in order to increase their preference for outpatient pre-registration at large hospitals,hospitals should work to explore and improve approaches for outpatient pre-registration,and better their service quality,which will involve greater participation of both the hospital staff and residents.

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.

Objective To explore the relationship between TLR3 mRNA expression on peripheral blood mononuclear cells(PBMCs)and acute rotavirus(RV)diarrhea.Methods Sixty-one children with acute RV diarrhea served as study subject,the expression of TLR3 mRNA on PBMCs was detected by real-time fluorescence quantitative RT-PCR.the concentrations of IFN-γand TNF-α in serum were measured by the method of Enzyrme-linked immunosorbent assay(EUSA).Results The expression of TLR3 on PBMCs and the serum levels of IFN-γ and TNF-α in the serious diarrhea group were 0. 820±0.051,(33.67±12.88)Pg/ml, (62.21±14.65)pg/ml,respectively,while it were 0.717±0.040,(24.01±10.06)pg/ml,(50.99± 12.18)pg/ml in the slight diarrhea group,and 0.525±0.029,(12.52±5.19)pg/ml,(28.65±7.44)pg/ml in the control group.Compared with the control group.the expression of TLR3 on PBMCs and the serum levels of IFN-γ,TNF-α in the serious and slight diarrhea group were significantly higher(P<0.01).There were significant differences between the serious and slight diarrhea group(P<0.01).There were positive relationship between the expression of TLR3 on PBMCs and tHe serum IFN-γ,TNF-α levels(r=0.431,P< 0.05,r=0.372,P<0.05).Conclusion The expression of TLR3 on PBMCs in children with acute rotavirus dialThea iS up-regulated,TLR3 and its mediated immune response are associated with the development of acute rotavirus diarrhea.

Objective To investigate the expression of nuclear factor kappa B (NF-κB),tumor necrosis factor α (TNF-α) and interleukin6 (IL-6) in human colorectal carcinoma tissues,and to explore their clinical significances in the genesis and development of colorectal cancer.Methods Sixty cases of colorectal cancer tissues and 36 cases of colorectal adenoma tissues were collected,60 cases of paracancerous normal colorectal tissues were the controls.Immunohistochemistry SABC method was used to detect the expression of NF-κB,TNF-α and IL-6 in each group respectively.The correlation of NF-κB,TNF-α and IL-6 with clinical pathologic features of colorectal cancer was analyzed.Results In colorectal carcinoma,adjacent normal colorectal tissues and colorectal adenoma tissues the positive expression rates of NF-κB were 76.7 ％ (46/60),46.7 ％ (28/60),83.3 ％ (30/36),the positive rates of TNF-α were 70.0 ％ (42/60),36.7 ％ (22/60),66.7 ％(24/36),the positive rates of IL-6 were 80.0 ％ (48/60),43.3 ％ (26/60),61.1％ (22/36).The differences were significant in each group (all P ＜ 0.05).The expression of NF-κB was closely associated with the expression of TNF-α and IL-6 respectively.In addition,the expression of NF-κB and TNF-α were correlated with vascular invaded,lymphnode metastasis and different stages.The expression of IL-6 was correlated with lymphnode metastasis and different stages.Conclusion The over expression of NF-κB and the downriver inflammation factors have close relationship with biological behaviors of colorectal cancer.It may be considered that the pathway of NF-κB play an important role in the genesis and development of colorectal cancer.

SUMMARY Regenerationofbonetissue,aswellasothertissues,requiresinvolvementandinteraction of cells,scaffolds and relevant growth factors,among which growth factors play a crucial role in maintai-ning the stability of microenvironment.Nel-like-type 1 molecule (NELL-1 ),a novel growth factor in tis-sue engineering,has been studied intensively in recent years.Researches mainly covered gene and pro-tein structure and their expression profiling,biological function,molecular mechanisms and disease rele-vance.NELL-1 expressed in embryonic tissue is essential for growth and development of bone tissue. NELL-1 presents excellent abilities of inducing bone and cartilage regeneration,especially with high spe-cificity to chondrocyte lineage.Compared with classic osteogenic growth factor bone morphogenetic pro-tein 2 (BMP-2),the process of osteogenesis interacted with NELL-1 exhibits stronger specificity,higher bone density and fewerside effects.Furthermore,a recent study shows synergistic effects of NELL-1 and BMP-2.NELL-1 enhances the osteogenic reaction induced by BMP-2 of cells and notably declines in-flammation response caused by BMP-2.This review evaluates the current research progress of the function and application of NELL-1 by the systematic method of evidence-based medicine.
