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):457-62
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.
4.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.

7.Characterization of human IL-2 mRNA
Chinese Journal of Immunology 1985;0(06):-
Large scale preparation of human IL-2 mRNA was obtained from human spleen cells stimulated with PHA+TPA at the peak of IL-2 mRNA transcription. Full length of IL-2 mRNA was translated in wheat germ extract to produce bioactive IL-2 (tIL-2). The IL-2 mRNA was about 14 S depending on the 7 M Urea-SDS-PAGE, and recovried from gel and translated in vitro. The elute curve of tIL-2 was the same as that of recombinant IL-2 (rIL-2) and natural IL-2 (nIL-2), the molecular weight of tIL-2 was about 14.000 dalton. The translational process of IL-2 mRNA in vitro was inhibited when RNA was cultured with RNase or translated product was cultured with proteinase, proving a standard in-vitro translation.
8.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.
9.Diagnosis and surgical treatment of xanthogranulomatous cholecystitis
Journal of Clinical Hepatology 2017;33(2):247-252
Xanthogranulomatous cholecystitis (XGC) is a rare type of chronic cholecystitis characterized by severe proliferative fibrosis with infihration of macrophages and foamy cells in the gallbladder wall.Since XGC and gallbladder carcinoma have similar clinical manifestations and radiological features,XGC is often misdiagnosed as gallbladder carcinoma in clinical practice,which leads to unnecessary extensive surgical resection and has an adverse effect on patients.At present,the preoperative diagnosis of XGC is still based on imaging results (ultrasound,computed tomography,and magnetic resonance imaging),and a definite diagnosis of this disease relies on intraoperative frozen biopsy or postoperative pathological examination.Meanwhile,XGC should be differentiated from gallbladder adenomyomatosis,gallbladder carcinoma,and gallbladder actinomycosis.Laparotomy or laparoscopic cholecystectomy is the major method for the treatment of XGC,but laparoscopic cholecystectomy is associated with a longer time of operation,more complications,and a higher rate of conversion to laparotomy.Therefore,surgeons are facing difficulties in preoperative diagnosis and intraoperative decision-making process of XGC.
