Chinese Journal of Tissue Engineering Research 2008;12(13):2596-2600
AIM: Based on the principle of ergonomics theory, to propose the hypothesis of rehabilitation medicine to promote standardization of rehabilitation medicine. METHODS: Through survey, observation, and experiment, human physiological and psychological factors were analyzed. Scientific ergonomics design, planning, and management were used to enhance the clinical value of rehabilitation medicine efficacy in evidence-based medicine. RESULTS: Ergonomics-based rehabilitation can resolve common defects in rehabilitation clinical work and management, and promote the standardization of medical rehabilitation objectively and scientifically. CONCLUSION: Ergonomics-based rehabilitation medicine is more objective, scientific and practical, and the repeatability of rehabilitation treatment is improved. It is worth further clinical study.

Objective To investigate the altered lipid in systemic sclerosis(SSc),and the relationship between the altered lipid and inflammation.Methods A total of 58 SSc patients were recruited into SSc group,and 58 healthy persons were recruited into control group from 2012 to 2014.Triglyceride(TG),total cholesterol(TC),low density lipoprotein-cholesterol(LDL-c)and high density lipoprotein-cholesterol(HDL-c),lipoprotein a[LP(a)],C-reactive protein(CRP)and erythrocyte sedimentation rate(ESR) were assessed using standard techniques in all cases,antinuclear antibody(ANA)and anti-Scl-70 antibody were assessed only in SSc patients.The levels of lipids between SSc patients and healthy controls,patients with antibody and patients without antibody were compared by using t test,corrections between lipid and inflammation were analyzed by Spearman′s correlation test.Results The clinical manifestations of SSc were mostly Raynaud′s phenomenon(91.4%),large area of black hard shin(87.9%),gastrointestinal manifestations(75.9%).The rates of an increased level of TG and decreased level of HDL-c were 29.3%,89.7% respectively.The level of TG in SSc was significant higher than in healthy controls(P =0.021),and the level of HDL-c in SSc was significant lower than in healthy controls(P =0.033).The levels of lipids in patients with ANA and anti-Scl-70 antibody had no significant difference with the patients without ANA and anti-Scl-70 antibody (P >0.05 ).Spearman′s correlation test demonstrated that HDL-c level correlated negatively with serum CRP (r=-0.285,P =0.039)and ESR (r =-0.271,P =0.043)in SSc.Conclusion Dyslipi-demia is a common feature in SSc patients that are characterized by an increase in TG and a decrease in HDL-c,inflammation might partly account for the changes.
3.Pentapeptides prevent enterovirus 71 proliferation in rhabdomyosarcoma cells and mice.
Acta Pharmaceutica Sinica 2014;49(4):457-462
Enterovirus 71 (EV71) is the main causative agent of hand, foot, and mouth disease (HFMD). This article presented the inhibitory activity of pentapeptides on the EV71 infection in rhabdomyosarcoma (RD) and suckling mice. The EV71 VP1 capsid protein expression levels and mRNA levels were analyzed by Western blotting and real-time PCR. The antiviral activity of pentapeptides in vivo was evaluated by weight changes and EV71 VP1 protein expression levels in intestines of suckling mice. Results revealed that the pentapeptide P010157 was able to inhibit EV71 replication in RD cells. After being incubated with the P010157 at a concentration of 100 microg x mL(-1) for 48 h, the level of EV71 vp1 mRNA in RD cells decreased by (92.0 +/- 6.3)%. The estimated EC50 was 2.2 microg x mL(-1). P010157 was able to inhibit EV 71-induced cytopathic effect (CPE) in RD cells. The cytotoxic activity of the compound was evaluated against RD cells by MTS assay. The results showed that P010157 had no obvious toxicity. In addition, the treated mice with P010157 did not exhibit weight loss, as was observed in untreated mice. EV71 replication reduced significantly as revealed by Western blotting. These findings suggest that P010157 could prevent EV71 proliferation in vitro and in vivo. P010157 is a novel compound for antiviral therapies against EV71, which merited further investigation.

Serum dehydroepiandrosterone sulphate (DHEA-s) level in obesity group was higher than that in control group. The rate of abnormally raised serum insulin value in obesity group was 50% (22/44), versus 18.2% (4/22) in non-obesity group and and 4.8% (1/21) in control group (P
6.Intraspinal Neurilemmoma:MRI Versus Pathologic Diagnosis
Journal of Practical Radiology 1992;0(11):-
Objective To study the correlation between MRI features and pathology of intraspinal neruilemmoma.Methods MRIfeatures of intraspinal neurilemmomas proved by operation and pathology in 16 cases were analysed retrospectively and in comparison with the results of pathology.Results All the tumors were intradural-extramedullary in location,including 6 in the cervical regions,5 in the upper thoracic regions,3 in the thoracic-lumbar junction and 2 in the lumbar regions.On MRI,the tumors were marginate elliptical heterogeneousisointense or slightly low intense with punctate or patchy more low intensity areas on T_1WI and heterogeneous slightly high intense orisointense with punctate or patchy more high intensity areas on T_2WI.Parts of the masses obviously enhanced with no enhancement of more low intensity areas on T_1WI.All of above imaging manifestations were corresponding to pathology of intraspinal neurilemmomas.Interlace of Antoni A and Antoni B was attributed to heterogeneous intensity.Antoni B that was no obviously enhancement was concentrated in bleeding and cystic areas and Antoni A that was obviously enhancement was concentrated in cellular area and collagen.Conclusion The imaging manifestations of intraspinal neurilemmoma is due to its varied pathologic changes,and this has guiding significance to the correct diagnosis.

8.EFFECTS OF 17?-ESTRADIOL ON HYPERTROPHY IN CULTURED NEONATAL RAT CARDIOMYOCYTES
Acta Anatomica Sinica 1957;0(04):-
Objective To observe effects of 17?-estradiol on phenylephrine-induced hypertrophy in cultured neonatal rat cardiomyocytes and to explore its mechanisms. Methods Using cultured neonatal rat cardiomyocytes treated with different factors as a model,surface area of cardiomyocytes was measured by computer photograph analysis software;the protein synthesis rate was assayed with leucine intake method;the proto-oncogene c-fos protein expression was assessed with immunocytochemistry technique;the markers of cardiomyocyte hypertrophy,embryonic genes such as ?-MHC\,?-skA and ANP mRNA expressions were assessed with semiquantitative reverse transcription-PCR. Results 17?-estradiol inhibited obviously phenylephrine-induced increase of surface area and the protein synthesis rate of cardiomyocytes,reduced c-fos protein expression of hypertrophic cardiomyocytes,and down-regulated ?-MHC、?-skA mRNA expressions and up-regulated ANP mRNA expression.Conclusion 17?-estradiol inhibits hypertrophy of cardiomyocytes and its mechanisms might be related with the suppression of c-fos protein expression,the reversion of the embryonic switching of contractile protein genes(?MHC and ?-skA),the increase of ANP mRNA expression.
