OBJECTIVETo evaluate digital rectal examination (DRE) , transrectal ultrasonography (TRUS) , free/total (f-PSA/ t-PSA) prostate-specific antigen (PSA), and PSA density (PSAD) in the diagnosis of prostate cancer (PCa) in patients with PSA < or = 4.0 microg/L.

METHODSBetween April 1996 and December 2012, a total of 343 subjects, aged 30 -91 years, with PSA < or =4.0 microg/L and abnormal findings on DRE or TRUS underwent prostatic biopsy. Based on the levels of PSA, the subjects were divided into four groups: 0 -1.0, 1.1 -2. 0, 2.1 -3. 0, and 3.1 -4.0 microg/L. The diagnostic values of DRE, TRUS, f-PSA/t-PSA, and PSAD were assessed in those with different PSA levels. According to the age, the subjects were again divided into five groups: C49 yr, 50 -59 yr, 60 -69 yr, 70 -79 yr, and > 80 yr. The rates of PCa detection in relation to PSA levels were estimated in different age groups.

RESULTSOf the 343 subjects, 65 (19.0% ) were diagnosed with PCa, with detection rates of 16.28% (21/129) , 17. 17% (17/99), 21.82% (12/55), and 25.00% (15/60) in those with the PSA levels of 0 -1.0, 1.1 -2.0, 2.1 -3.0, and 3.1 -4.0 microg/L, respectively. There were statistically significant differences in f-PSA/t-PSA between the PCa patients and non-PCa subjects with the PSA level > 2.0 microg/L (P <0.05) , but not with the PSA level < or =2.0 microg/L (P > 0.05) , nor did PSAD show any significant difference between the PCa and non-PCa groups ([0.09+/-0. 16] versus [0. 06 +/- 0. 07] micro/L/ml, P > 0. 05). The rate of cancer detection rose -with the elevation of the PSA level, but had no statistically significant difference among different age groups (P >0.05).

CONCLUSIONPSA 2.1 -4.0 microg/L with abnormal DRE and TRUS findings should be considered as a warning signal, which requires regular follow-up and PSA detection. With f-PSA/t-PSA <0. 15 with or without abnormal DRE and TRUS findings, routine prostate biopsy should be performed. PCa diagnosis cannot be effectively established by DRE, TRUS, f-PSA/t-PSA, and PSAD in those with PSA < or = 2.0 microg/L.

OBJECTIVETo compare the difference in the clinical efficacy on perennial allergic rhinitis between three nasal points acupuncture therapy and the oral administration of loratadine so as to provide the better acupuncture program in clinical treatment.

METHODSSixty cases were randomized into an acupuncture group (30 cases) and a medication group (30 cases). In the acupuncture group, acupuncture was applied to three nasal points [Yingxiang (LI 20), Yintang (EX-HN 3), Bitong (Extra)] and acupoints selected by syndrome differentiation. Acupuncture was given once every two days, three times a week, for 4 weeks totally. In the medication group, loratadine was prescribed for oral administration, 10 mg every day, for 4 weeks. The symptom and physical sign scores before and after treatment, as well the short-term and long-term efficacy were compared between the two groups.

RESULTSThe total effective rate was 96.7% (29/30) in the acupuncture group and was 93.3% (28/30) in the medication group after treatment. The efficacy was similar between the two groups (P>0.05). In follow-up, the total effective rate was 86.7% (26/30) in the acupuncture group, which was better than 56.7% (17/30, P<0.05) in the medication group. The scores of symptoms and physical signs after treatment and in follow-up were all reduced apparently as compared with those before treatment in the patients of the two groups (all P<0.05). The scores of symptoms and physical signs were reduced more apparently in the acupuncture group as compared with those in the medication group in follow-up (all P<0.05).

CONCLUSIONThe acupuncture at three nasal points and the acupoints selected by syndrome differentiation achieves the similar short-term efficacy on perennial allergic rhinitis as compared with the oral administration of loratadine. The acupuncture therapy presents the obvious advantages on long-term efficacy.

Objective To explore the definition, structure, terminology, framework, and models of social support and services, and mea-surement of intellectual disability based ICF approach. Methods The ICF approach and definition and approach proposed by American Asso-ciation on Intellectual and Developmental Disabilities (AAIDD) were adopted. Results The characteristics of intellectual disability are sig-nificant limitations in both intellectual functioning and adaptive behavior as expressed in conceptual, social, and practical adaptive skills, and onset before 18 years old. The framework, domains and contents of services and support for intelligence disability were proposed, as well as the updated measurement of intelligence disability based on new framework and definition. Conclusion The new framework of intel-ligence disability, system of service and support, and measurement are in accordance with the bio-psycho-social model of disability of ICF. The new paradigm will provide framework and tool of measurement, rehabilitation, education, and social services for people with intelli-gence disability.

There are similarities between magnetotactic bacteria and Acidithiobacillus ferrooxidans (A. ferrooxidans) which isolated from Acid mine drainage(AMD). The weak magnetotaxis of some bioleaching bacteria isolated were found by microscope. A magnetophoresis apparatus was designed based on these weak magnetotaxis and be used to analysis the movement of these strains. The physiological properties of the anear magnetic field strain and removed magnetic field strain which isolated successfully by magnetophoresis apparatus have large difference. The nanometer magnetic particles was extract from the Acidithiobacillus ferrooxidans which purified by spread plate method from AMFS and its main elements are Fe and O by energy spectrum analysis. The results show that A. ferrooxidans have weak magnetotaxis and can be isolated by magnetophoresis. With the development of this new isolating method, the research of magnetotactic bacteria and bioleaching will get more benefit from it.
