As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

Objective To study clinical significance of anti-momoner C-reactive protein (anti- mCRP) antibody in systemic lupus erythematosus (SLE) and assess the relationship between serum CRP and anti-mCRP antibody.Methods Enzyme-linked immunosorbent assay (ELISA) was applied to determine serum level of anti-mCRP antibody in 113 pateints with SLE,65 patients with other rheumatic diseases,including primary Sjgren syndrome,rheumatoid arthritis,osteoarthritis,ankylosing spondylitis and systemic sclerosis,and 32 healthy controls.Serum level of CRP was evaluated by turbidimetry.Clinical manifestations and laboratory indicators of the patients were all recorded.Results Serum level of anti- mCRP antibody in SLE patients was significantly higher than that in patients with other rheumatic diseases and healthy controls,respectively (t=2.502 and 5.352,respectively,P 0.05).Titer of anti-mCRP antibody closely correlated with systemic lupus erythematosus disease activity index score (r=0.248,P0.05). Conclusions Level of Anti-mCRP antibody increased significantly in patients with SLE,which associated with disease activity of SLE and can be used as a valuable marker in evaluating activity of SLE.

Two Pseudomonas strains, K80 - B and K80 - A, can use hydrocarbon as carbon source by two different mechanisms. Different effects can be observed when they are applied to 69-8 oil of Dagan Oil Field. The strain K80-B producing both hydrocarbon pseudosolubilizing factor and hydrocarbon emulsifying factor can decrease the viscosity and solidifying point of the 69-8 oil 51.6% and 2℃ respectively. Whereas the other can only decrease 43.5% and 3℃ respectively. When the two strains are mixed, synergistic effect on crude oil is obvious.

OBJECTIVETo study and evaluate the curative effect and mechanism of Qiangxin Granule (QXG) in intervening chronic heart failure (CHF) rats with Xin-qi deficiency complicated blood stasis and edema syndrome (XQD-BS-ES).

METHODSTotally 72 SD rats of clean grade were randomly divided to the normal control group (n =10) and the model group (n = 62). The XQD-BS-ES rat model was established by adriamycin plus propylthiouracil method. Survived modeled rats were then randomly divided to 5 groups i.e., the model group (n = 11, administered with normal saline by gastrogavage), the Western medicine (WM) group (n =11 , administered with perindopril and hydrochlorothiazide by gastrogavage), the low dose QXG (QXG(L)) group (n = 11, administered with 9.26 g/kg QXG by gastrogavage), the middle dose QXG (QXG(M)) group (n = 11, administered with 18.52 g/kg QXG by gastrogavage), the high dose QXG (QXG(H)) group (n = 11, administered with 37.04 g/kg QXG by gastrogavage). After 4 weeks of treatment, left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), brain natriuretic peptide (BNP), heart rate (HR), respiratory rate (RR), urine output, ear temperature, exhaustive swimming test (EST), tri-iodothyronine (T3), tetra-iodothyronine (T4), thyroid stimulating hormone (TSH), as well as heart, lung, liver weight index and their pathological sections, and high sensitivity C-reactive protein (HS-CRP), angiotensin II (Ang II), carbohydrate antigen 125 (CA125) were detected and compared.

RESULTSCompared with the normal control group, LVEF, LVFS, BNP, HR, RR, urine output, ear temperature, EST, T3, T4, TSH, HS-CRP, Ang II, and CA125 changed significantly in the model group (P < 0.01). Compared with the model group after treatment, LVEF, LVFS, BNP, urine output, EST, T4, heart and liver weight index, HS-CRP, Ang II, CA125 were significantly improved in each QXG group (P < 0.05, P < 0.01). Moreover, TSH was improved in the QXGL and QXG(M) groups (P < 0.05); ear temperature and T3 in the QXG(M) were also improved (P < 0.05); the lung weight index decreased in the QXG(M) and QXG(H) groups (P < 0.01). Compared with the WM group, T4 and CA125 were obviously improved in all QXG groups (P < 0.01); BNP and ear temperature were obviously improved in QXG(L) and QXG(M) groups (P < 0.05, P < 0.01); LVEF, LVFS and TSH were obviously improved in the QXG(M) group (P < 0.05, P < 0.01). And as far as each treatment group, LVEF, LVFS, urine output increased significantly after treatment (P < 0.01); EST obviously increased in QXG(M) and QXG(H) groups (P < 0.01); ear temperature increased in all QXG groups (P < 0.05, P < 0.01). Moreover, compared with the model group, pathological changes of heart, lung, and liver were improved to some degree in each treatment group, especially in the QXG(M) group.

CONCLUSIONSGood curative effect was shown in each QXG group. QXG could improve LVEF, LVFS and BNP of CHF rats of XQD-BS-ES, as well as T3, T4, TSH, EST, urine output, and ear temperature. Moreover, QXG showed superiority than WM group in this respect.

OBJECTIVETo establish and evaluate chronic heart failure (CHF) rat model of Xin-qi deficiency complicated blood stasis and edema syndrome (XQD-BSES).

METHODSTotally 40 SD rats were randomly divided into the normal control group (Control), the propylthiouracil (PTU) group, the adriamycin (ADR), and the ADR + PTU group. Normal saline was used as equivalent solvent of each group. Rats in the Control group were intragastrically and intraperitoneally injected with normal saline. Rats in the PTU group were intragastrically injected with PTU suspension and intraperitoneally injected with normal saline. Rats in the ADR group were intragastrically injected with ADR solution and intraperitoneally injected with normal saline. And rats in the ADR + PTU group were intragastrically injected with PTU suspension and intraperitoneally injected with ADR solution. The dose of PTU was 0.2% of daily forage weight, once daily. The dose of ADR was 3.5 mg/kg, once per week. The modeling lasted for 6 weeks. Left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), brain natriuretic peptide (BNP), heart rate (HR), respiratory rate (RR), urine output, ear temperature, exhaustive swimming test (EST), Tri-iodothyronine (T3), tetra-iodothyronine(T4), thyroid stimulating hormone (TSH) as well as heart, lung, liver weight indices and their pathological sections were integrated and compared.

RESULTSCompared with the Control group, LVEF, LVFS, BNP, HR, RR, heart, lung, liver weight indices, urine output, ear temperature, EST, and T3, T4, and TSH changed significantly in the ADR group, the PTU group, and the ADR + PTU group with statistical significance (P < 0.05), and pathological changes of heart failure occurred in pathological sections of heart, lung, and liver. Compared with the ADR group, LVEF, LVFS, BNP, and lung, liver weight indices, urine output, ear temperature, T3, T4, and TSH changed significantly in the ADR + PTU group with statistical significance (P < 0.05), and pathological changes of heart failure were more serious in pathological sections of heart, lung, and liver. Compared with the PTU group, LVEF, LVFS, BNP, HR, RR, urine output, EST, T4, heart and lung weight indices changed significantly in the ADR + PTU group with statistical significance (P < 0.05), and pathological changes of heart failure were quite serious in pathological sections of heart, lung, and liver.

CONCLUSIONADR + PTU was an appropriate method to establish CHF rat model of XQD-BSES.

Objective To assess the feasibility of using PET molecular imaging to evaluate the therapeutic effects of traditional Chinese medicine FuZhiSan (FZS) on the model of aging Alzheimer's disease (AD) rats. Methods Twenty aged AD rats (Sparague-Dawley rats,male) were randomly divided into FZS treated group (n = 10) and control group (n = 10). Another 10 healthy adult rats were as blank controls. Morris water maze record system was used for cognitive function assessment. Before and after FZS treatment 18 F-fluorodeoxyglucose (FDG) and 11 C-2- [4'-(methylamino) phenyl] benzothiazol-6-ol ( PIB )PET imaging was undertaken. After post-treatment imaging procedures the brain tissues of all animals were taken for histochemical study,such as staining with HE,congo red,amyloid β (Aβ) immunofluorescence,5-bromo-2-deoxyuridine (BrdU) immunofluorescence and NeuN immunofluorescence. Paired t-test was performed with SPSS 13.0 software for the data analysis. Results The cognitive dysfunction of aging AD rats was improved after FZS treatment. The escape latency in FZS treated group was significantly shorter than that of control group ((32.5 ±10.8) s vs (102.6±8.8) s,t =15.7987,P=0. 0001). Diffuse neuronal loss and Aβ deposition were detected in the hippocampus and cortex in the aged AD rats. The imaging data showed that brain glucose metabolism was amended in FZS treated group while the abatement of amyloid deposition was not significant. Immunofluorescence results indicated that the neuronal proliferation was more remarkable in FZS treated group. Conclusions It may be feasible to use PET imaging as a method to evaluate the therapeutic effect in AD rats. FZS may ameliorate memory dysfunction of aged AD rats. Its mechanism may be partly contributed to the enhancement of the neuronal proliferation and survival.

Aim To evaluate the effects of salvianolic acid B ( Sal B ) on bone metabolism and its potential mechanism in high fat diet ( HFD) mice.Methods Thirty C57BL/6J male mice were divided into three groups with 10 mice each, namely normal , HFD and HFD+Sal B.HFD and HFD+Sal B mice were treated with HFD, and HFD+Sal B group mice were also with Sal B (125 mg· kg -1· d-1).After 12 weeks' treat-ment, femurs were harvested .The effects of Sal B on biomechanical strength were evaluated by biomechani-cal tests, and the effects of Sal B on bone microstruc-ture were evaluated by Safranin O/fast green staining and hematoxylin and eosin staining .The expression of nuclear factor-kappa B ( NF-κB)-p65 and NADPH ox-idase 4 ( Nox4 ) and cathepsin K in femurs was deter-mined by immunohistochemical staining . Results Maximum load and elastic load significantly decreased ,and the trabeculae became thinner and irregular in the femurs of HFD mice , while Sal B treatment could re-verse the descending biomechanical strength and the disorganized femurs bone micro-structures in HFD mice.In addition, the expressions of Nox4, NF-κB-p65 and cathepsin Kmarkedly increased in HFD mice , and Sal B possessed the ability to down-regulate the ex-pression of Nox4, NF-κB-p65, and cathepsin K in the femurs triggered by HFD .Conclusions Sal B treat-ment improves bone metabolism via regulating Nox 4/NF-κB/cathepsin K signaling pathway in HFD mice . The findings contribute to the understanding and exten-sion of the applications of Salvia miltiorrhiza and its constituents on osteoporosis .

INTRODUCTIONProblem-based learning (PBL), a pedagogic concept using a student-centred approach and problem-solving through small group discussions, has been adopted in varying degrees for years at all 11 medical institutes in Taiwan. Much evidence has shown that a number of factors can seriously affect student performance in PBL courses, such as the design of PBL scenarios, the tutors' character and students' attitudes and efforts.

MATERIALS AND METHODSThe aim of this study was to examine how the personal characters or knowledge base of Taiwanese medical students influence their performance in a hybrid-PBL curriculum. A total of 309 (234 male, 75 female) high-school entry undergraduate medical students participated in this survey. Self-assessed personal traits were presented in a 44-item questionnaire with a Big Five factor structure. Knowledge base was assessed by students' score point average (SPA) based on their previous 4-year education in medical school. Peer-assessed performance of students in the PBL curriculum was carried out using a well-developed, reliable and validated evaluation form.

RESULTSEach student's peer-evaluated PBL performance can be divided into 5 principal components, which included control-lead, assist-coordinate, written organisation and compromise- comply (Eigen value >1). The consistency and reliability of the Big Five questionnaire on personal traits was analysed and discordant items were deleted (Cronbach's alpha = 0.72 to 0.86 after deletion). The relationship between the personal traits, knowledge base and PBL performance, as analysed by simple regression, showed that "extraversion" and "openness to experience" were positively related to the "assist-coordinate" characteristic in PBL performance, and "conscientiousness" was positively related to the "control-lead" characteristic in PBL performance. The SPA was positively related to the "assist-coordinate" or "control-lead" characteristic in PBL performance. The "agreeableness" was negatively correlated with the "control-lead" characteristic in PBL performance. After stepwise regression between the Big Five and each component of PBL performance, only the correlation between conscientiousness and control/lead, and between extraversion and assist/coordinate remained significant.

CONCLUSIONKnowledge and personality characteristics appear to be associated with student performance in a hybrid-PBL curriculum. The implications of this study on the future development and application of this assessment tool in medical schools are presented.

INTRODUCTIONOrthodeoxia is a rare clinical syndrome characterised by dyspnoea and arterial deoxygenation that accompanies a change from a supine to erect position.

CLINICAL PICTUREWe describe an unusual case of "paradoxical orthodeoxia" in a 70-year-old man with a thoracic aortic aneurysm: arterial desaturation when supine that improved when erect.

TREATMENT AND OUTCOMENon-invasive imaging revealed compression of the left pulmonary artery by the aneurysm (thoracic computed tomography) and patent foramen ovale (transesophageal echocardiography). Nuclear studies show decreased relative left lung perfusion attributable to the former, and right-to-left atrial shunt attributable to the latter. The degree of right-to-left shunt increases in the supine position: nuclear pulmonary shunt study shows shunt extent of 21% when supine versus 10% erect.

CONCLUSIONA physioanatomical explanation is proposed.
