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.The expression of COX-2, VEGF, MMP-2 and P-glucoprotein in carcinoma of stomach and its significance
Journal of Chinese Physician 2009;11(7):917-918
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.

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.
7.Application and prospect of fast-track surgery in gastric cancer
International Journal of Surgery 2017;44(5):357-360
Fast-track surgery is the basis for the use of new medical evidence to optimize the management of perioperative patients.The surgeon forms a set of perioperative treatments by integrating and applying these new evidences to reduce the physical and psychological stress response of patients,and to speed up the rehabilitation of patients.Fast-track Surgery has been used in the treatment of a variety of diseases,including cardiac surgery,total knee replacement,and colorectal surgery.Gastric cancer was the fourth in the most common cancer sorts and the second in death rate in the world.Surgery is a milestone in the treatment of gastric cancer,and is the only effective means to cure.Fast-track surgeryy in the treatment of gastric cancer is still constantly improving.This article reviews the application of fast-track surgery in gastric cancer surgery.

10.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.
