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.

Objective To investigate the expression of COX-2, VEGF, MMP-2 and P-g]ycoprotein in carcinoma of stomach and its significance. Method The expressions of COX-2, VEGF and P-glycoprotein inside and beside the tumor tissues of 57 cases carcinoma of stomach were detected with immunohistochemistry method. Result The expressions of COX-2, VEGF, MMP-2 and P-glyeoprotein inside the tumor tissues were significantly higher than that beside the tumor(χ2 = 5.29,5.37,5.62,4.87 ; P < 0.05). The expressions of COX-2, VEGF and MMP-2 were different among different carcinoma metastasis (χ2 = 5.97, 6.17,6.09 ; P < 0.05). P-glucoprotein expressions were positive correlated with gastric cancer(rs' = 0.674,0.65,0.67 ; P < 0.05). Conclusion COX-2, VGEF, MMP-2 and P-glyeopretein were some correlated and overexpressed in stomach carcinoma, which may take part in the genesis, development and multi-drug resistance of this cancer.

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.

The changes of lysosomes of the hepatocytes in 27 healthy female rats aged 1, 5, 15, 30, 50, and 90 days respectively were observed on morphometry and by studying the ultrastructures with electron microscope. The results are as following:1. The volume density and numerical density of the lysosomes of rat hepatocytes are markedly increased as the age increases.2. The lysosomes originally scattered in cytoplasm gradually migrate to the periphery of bile canaliculi.3. The proportion among certain forms of secondary lysosome changes as the rats grow older and the alteration of autophagic vacuoles is more prominant than others.The significance of the lysosome changes mentioned above was discussed. The author, considering from all the results, suggests that the time around five days after the birth of the rats is a critical period for the development of the lysosomes of rat hepatocytes.

The development of the nerves of the small intestine was studied in 26 human fetuses with the gestational age of 11 to 40 weeks.The findings are as follows:(1)The distance between the Auerbach's ganglia and the muscular layer is small in the early fetal period and it increases progressively as the fetus grows.(2)The density of neuropils increases gradually.(3)The number of large gradual vacuoles (LGV) is small in the 3rd month of gestation,and it increases gradually and is quite numerous in the 6th month.(4)The morphology of the synapses is not so typical as that of an adult.(5)The peak values of the stereological morphological parameters of the organelles in the neurons appear between the 4th-6th month and maintain at a relatively high level until the baby is bron.

Objective To investigate the regulatory effect of TNF ? on the expression of plasminogen activator inhibitor 2(PAI 2) and its biological significance. Methods Using immunocytochemistry(ICC), terminal deoxynucleotidyl transferase mediated end labeling (TUNEL) and ICC/TUNEL double label methods, the expression of PAI 2 in and the apoptosis of the cultured epidermal keratinocytes treated by TNF ? were detected. Results After the mouse epidermal keratinocytes were incubated with TNF ?, compared with the unshed cells, the expression of PAI 2 in shed cells and the cellular apoptosis increased obviously. The increased PAI 2 expression also appeared in the apoptotic cells, especially in larger and multi angled apoptotic cells. Conclusion In highly differentiated epidermal keratinocytes, TNF ? can enhance the expression of PAI 2 as well as apoptosis. Furthermore, according to the relation with the keratinocytes apoptosis, there are two types of PAI 2 induced by TNF ?, one of which is related to apoptosis, but the other is not.
