OBJECTIVE To investigate the knowledge about hand hygiene among the outpatients and then take some valid methods to enhance their understanding about hand hygiene.METHODS By randomly asking patients from two departments in a level A of the tertiary hospital,one was a digestion and the other was a non-digestion department question designed by ourselves.The data were generally described by percentage and ?2 test with SPSS 6.0.RESULTS All the patients had not enough and correct hand hygiene knowledge from both two groups.The patients from digestion department paid more attention on their hand hygiene than from non-digestion one.The most patients from both two groups thought they needed to know more about hand hygiene and hospital should equipped with some fast hands cleaning instruments.CONCLUSIONS It is a very important duty for nurses to explain and publicize more about general hygiene and show patients how to clean their hands in order to decrease hospital infection.

Aim To study the chemical constituents of Rhododendron ovatum Planch. Methods The chemical constituents were isolated and purified by silica gel column chromatography and identified on the basis of their physiochemical and spectral data. Results Seven compounds were isolated and identified. Their structures were established as 3,5,7-trihydroxylchromone 3-O-β-D-xylopyranoside (I), taraxerol (II), β-sitosterol (III), betulinic acid (IV), quercetin (V), quercetin-3-O-α-L-rhamnopyranoside (VI), and D-glucose (VII). Conclusion Compound I is a new compound. Compounds II-VII were isolated from this plant for the first time.

Objective To study the effects of estrogen on the cultured osteoclasts in vitro. Methods The acid phosphatase (ACP) and tartrate resistant acid phosphatase (TRAP) activities were measured kinetically and the introcellular hydrogen ions were calculated with the confocal laser scanning microscopy(CLSM). The area and number of the resorption pits were determined with the Leica Quantimet 500 system. Bone resorption pits were observed with scanning electronicmicroscope. Results With the estrogen concentration increased, the ACP and TRAP activities decreased from (1 69?0 13) U/L and (1 60?0 14) U/L to (1 16?0 31) U/L and (0 93?0 34) U/L, respectively (experiment group vs control group, P

Objective To evaluate the clinical efficacy of Yinhe gargle on infected root canals. Methods Forty-seven cases of root canal infection ( involving 48 affected teeth) were randomly divided into two groups. The experimental group (22 cases involving 22 affected teeth) was given intracanal medicament with Yinhe gargle, and the control group ( 25 cases involving 26 affected teeth) was given root canal disinfection with camphor phenol. After intracanal medicament for one week, therapeutic effect and safety were evaluated in the two groups. Results ( 1) During root canal disinfection, none of the subjects had adverse reaction such as hypersensitiveness or cauterization of soft tissue. Canal obturation was available after the first intracanal medicament for the infected root canals. (2) After intracanal medicament for one week, the effective rate in the experimental group was 95.45%, and was 100.00%in the control group, the difference being in significant (P>0.05). Conclusion Yinhe gargle has similar disinfection effect to camphor phenol on infected root canals, and it can be used as disinfection medicament for root canals.

0.05).Ticlopidine could inhibit thrombosis induced by ferric chloride,but it did not influence TXB_2 and 6-keto-PGF_1? content and activities of AT-Ⅲ and PC in the plasma.Ticlopidine could enhance activity of t-PA in the plasma.It may be related to the decrease of t-PA consumption by inhibiting thrombosis.Antithrombosis action of ticlopidine may not be concerned to inhibiting production of TXB_2 of platelet.LMWH could inhibit thrombosis also,but it did not influence TXB_2 and 6-ketoPGF_(1?) content in the plasma.LMWH could enhance activities of t-PA and t-PA/PAI-1 ratio,which may be related to the promoting release of t-PA in vascular endothelial cells.LMWH could reduce activity of AT-Ⅲ,which may be concerned with combination of LMWH and AT-Ⅲ result in AT-Ⅲ consumption.Conclusion Ferric chloride may induce occlusive thrombosis in rats.Thrombosis may be associated with activation of platelet and blood coagulation system,lower of anticoagulative protein and fibrinolytic activity.

AIM: To investigate the expression and the significance of β-catenin and Cyclin D1 in gliomas. METHODS: The SABC immunohistochemistry were used to detect the expression of β-catenin and Cyclin D1 in 49 brain gliomas and 5 normal brain tissues. RESULTS: The β-catenin positive ratio in normal brain tissues and glioma samples are 2/5 and 38/49(P<0.01) respectively, and the Cyclin D1 positive ratio in normal brain tissues and gliomas are 1/5 and 42/49(P<0.01); Compared with the normal brain tissue, both the immunohistochemical expression of β-catenin and Cyclin D1 were up-regulated(P<0.05), and the expression of β-catenin and Cyclin D1 between the normal brain tissues and gliomas exhibited significantly difference (P<0.01). CONCLUSION: β-catenin and Cyclin D1 increased in gliomas may be precipitate the tumorigenesis of glioma.
