Objective To analyze the cost-effectiveness of integrated pharmaceutical care (IPC) in community-based patients with chronic obstructive pulmonary disease (COPD).Methods The COPD patients were divided randomly into intervention group (group A,n =79) and control group (group B,n =71).Group A received the IPC intervention measures,including serial lectures of pharmaceutical knowledge,home supervision and web-based communications for while group B group had none.Results As compared with group B,group A obviously improved on the knowledge of pharmaceutical treatment effect and side effect (95.1％,67.4％ vs.63.1％,21.9％,x2 =12.445,P=0.000 vs.x2 =55.557,P=0.000).There were notable differences between two groups [ ( 1.77 ± 1.23 ) vs.( 2.42 ± 1.66 ) s,t =2.583,P=0.011],pulmonary rales [ (0.01 vs.0.01)s,Z =2.370,P=0.018],6-min walk distance (6 MWD) [ (457 ± 67 ) vs.(425 ± 72) m,t =2.760,P =0.007 ],vital capacity ( VC ) [ ( 1.60 ± 0.25 ) vs.( 1.49 ± 0.23 ) L,t =2.718,P =0.007 ) ] andquality-of-life items ( 48 ± 10 vs.52 ± 11,t =2.624,P =0.010) after intervention.Analyze of cost-effectiveness show that groupA was superior to group B [ total effect total cost(TE/TC =764.6/4936,15.49％ )vs.(TE/TC =1509.4/4708),32.06％,x2 =6.183,P ＜ 0.01 ].Conclusion IPC can improve the disease condition and achieve excellent cost-effectiveness for community-based COPD patients.

Objective To investigate the chemopreventive potential of salvianolic acid B against 7,12-dimethylbenz(a)anthracene(DMBA)-induced hamster buccal pouch carcinogenesis with respect to angiogenesis. Methods(Sixty) male Syrian golden hamsters were randomly divided into 4 groups(group A and B,n=20;group C and D,(n=10).) DMBA solution(0.5% in acetone) was applied topically to the right cheek pouch of male Syrian golden hamsters in group A and B,while animals in group C were painted with acetone,3 times a week for 6 weeks.Animals in group D received neither DMBA nor acetone in the first 6 weeks.Two days after the last treatment of(DMBA,) animals in group B and D received salvianolic acid B daily(10 mg/kg) by gavage,while animals in group A and C received same volume of saline,for the next 12 weeks.At the end of the experiment,animals were sacrificed and tissue samples were collected for histopathological and immunohistochemical examination. Results Salvianolic acid B significantly decreased the incidence of squamous carcinoma(P

OBJECTIVE: To study ApoB gene genetic polymorphism of Han nationality and Mongolian nationality in midwest area of Inner Mongolia. METHODS: Some unrelated individuals of Han nationality and Mongolian nationality in midwest area of Inner Mongolia were selected. Polymerase chain reaction-restriction fragment length polymorphism technology was used to check the presence of Xba I (X+) and EcoR I (E-) sites of rare alleles. The genotype frequency, allelic frequency and population genetics parameters were calculated. RESULTS: The frequencies of Xba I (X+) and EcoR I (E-) rare alleles were 2% and 4.6% in Han population. There was no Xba I (X+) or EcoR I (E-) rare alleles found in Mongolian nationality. CONCLUSION The allelic frequencies of ApoB gene Xba I and EcoR I sites are very different in different races. These sites may be used in identification of ethnicity.

'Bronze teeth' reflect the mechanical properties of natural teeth to a certain extent. Their mechanical properties resemble those of a tough metal, and the gradient of these properties lies in the direction from outside to inside. These attributes confer human teeth with effective mastication ability. Understanding the various mechanical properties of human teeth and dental materials is the basis for the development of restorative materials. In this study, the elastic properties, dynamic mechanical properties (visco-elasticity) and fracture mechanical properties of enamel and dentin were reviewed to provide a more thorough understanding of the mechanical properties of human teeth.

Objective To retrospectively evaluate the mammographic features of breast ductal carcinoma in situ (DCIS)and DCIS with small invasive foci,and to analyze the correlation between the mammographic findings and the prognostic biologic factors.Methods The mammographic examination was performed in 95 consecutive women with breast DCIS(n = 50)and DCIS with invasive foci(n = 45 ).The prognostic biologic factors including progesterone receptor(PR),C-erbB-2,and p53 were evaluated in 62 of 95 cases.Categorical data were expressed as percentages and analyzed by using the X~2 test,and furthermore the odds ratio was measured.Results(1)Only one abnormality was seen on mammography in 62 patients. Combined two abnormalities on mammography were seen in 26 patients.Mammograms were normal in 7 patients.(2)Calcifications with or without other abnormality were noted in 62 cases.Of them,73% (n =45)had higher probability of malignancy calcifications and the others were intermediate concern calcifications.Clustered calcifications(36 lesions)was the most common distribution,which usually accompanied by another abnormality.And then were segmental(18 lesions)distributed pattern.As far as the shape of mass (n = 22)was concerned,the oval shaped lesion(13 cases)was the most common,and the margin of the mass appeared as ill-defined in 15 eases,microlobulated in 1,circumscribed in 4,and obscured in 2,respectively.Isodensity mass had a higher frequency in this group(12/22,55%).Other non-calcification findings included architecture distortion(7 cases),local asymmetry (15 cases),global asymmetry (5 cases),and solitary dilated duct (3 cases),and most of them accompanied with other signs. (3)For expression profile of the biological factors,significant differences were found among malignant calcification group,intermediate concern calcification group,and non-calcification group. The odds of PR positive for the lesions noted as non-calcification were 11.00 times higher (X~2 =8.571 ,P=0.003 ;95% CI, 1.998—60.572)than the lesions noted as intermediate concern calcifications,and 8.80 times higher (X~2 = 9.748,P=0.002 ;95% CI,2.024—38.253)than the lesions noted as malignant calcifications.The odds of C-erbB-2 positive for the lesions showed as malignant calcifications were 12.35 times higher (X~2=7.353, P=0.007 ;95% CI,1.447—105.443)than the lesions showed as non-calcification,and 5.74 times higher (X~2=4.977,P = 0.026;95% CI,1.110—29.645)than the lesions showed as intermediate concern calcifications.Conclusion The mammographic features of DCIS and DCIS with small invasive foci were characteristic.Mammographic findings could be a prognostic markers,which could provide a possibility for making a treatment plan.

BACKGROUNDTrichosporon asahii (T. asahii) is one of the most important pathogenic fungus in the genus of trichosporon. Although the species identification of T. asahii was based upon the complicated results of morphologic, biochemical and biologic examination, the morphology characteristic is still the first clue to the species. Some common structures of T. asahii had been described such as arthrofilaments and arthroconidia, but other important structures of T. asahii were unclear.

METHODSSix strains of T. asahii were incubated on the slant and micro culture of Sabouraud's dextrose agar at 30 degrees C for 7 days. Samples were fixed using 2% paraformaldehyde and 2.5% glutaraldehyde. T. asahii was observed under scanning electron microscope and transmission electron microscope.

RESULTSThe detailed characteristics of the diverse sites of germination, as well as some uncommon structures such as giant cell, sarcinate, and club-shaped macroconidia, were presented. The pseudohyphae of T. asahii were noted to produce true hyphae, either along the longitude axis or on the flank. T. asahii was noted to have blastic and thallic conidiation. Digitated branches, trichoid structures and septa inside the spores were detected.

CONCLUSIONThese results may add our knowledge to the structure and development of T. asahii.
