Objective To investigate the relationship between serum uric acid (SUA) and metabolism syndrome (MS) in community-based elderly population in Beijing.Methods A community-based and cross-sectional survey on 1821 elderly person was performed in Beijing in 2000.Questionnaire survey,physical examination and blood biochemical tests were conducted.Relationship of MS and its components with SUA was analyzed.Results Among 1821 subjects,there were 365 cases with MS (20.0％) and 1456 cases without MS (80.0％).SUA level was higher in MS group than in non-MS group [(5.20±2.27) μmol/L vs.(4.50±1.44) μmol/L,t=-7.34,P=0.000].All subjects were divided into 4 groups according SUA level:goup 1 (≤3.5μmol/L,n=443),group 2 (3.6 μmol/L-4.4 μmol/L,n=465),group 3 (4.5 μmol/L-5.4 μmol/L,n=446) and group 4 (≥5.5 μmol/L,n=467).SUA level was increased along with the increased BMI,TG,TC,LDL-C levels,and decreased along with the decreased HDL-C level,which had significant differences (F=43.07,9.32,22.36,8.19,9.39,all P＜0.001).There were significant distribution differences in MS components numbers in the 4 groups (x2=73.62,P=0.000).After adjusting for age,sex,residential,education level,marriage,smoking,drinking and exercise habits,logistic regression analysis showed that MS was related with SUA level,and the risk of MS was increased along with the increased SUA level.Conclusions MS is correlated with SUA level in elderly people.SUA level should be observed and controlled effectively in the elderly.

Objective To investigate the regulating effect of heat reinforcing acupuncture manipulation on body energy metabolism enzymes in rheumatoid arthritis (RA) and preliminarily explain the mechanism of heat-producing action of heat reinforcing acupuncture manipulation. Method Forty chinchilla rabbits were randomized into normal, model, equal reinforcement and reduction, twirling reinforcement, and heat reinforcing acupuncture manipulation groups. A model of cold syndrome-type RA was made by ovalbumin induction and exposure to low temperature in the other four groups not including the normal group. From two days after successful model making, the normal and model groups were grabbed and fastened (bound) by the same way as for the acupuncture groups, 30 min once daily. The equal reinforcement and reduction group received even reinforcing-reducing method;the twirling reinforcement group, twirling reinforcement method;the heat reinforcing group, heat reinforcing acupuncture manipulation. The needle was manipulated for 1 min and retained for 30 min once daily, for a total of seven days. The RA rabbit knee joint circumference was measured and the inflammation score was recorded according to synovial histopathological sections before and after treatment. After the completion of intervention, the rabbits were sacrificed and the articular synovium was rapidly separated for frozen sections. Articular synovium lactate dehydrogenase (LDH), succinate dehydrogenase (SDH) and cytochrome oxidase (CCO) activities were measured by histochemical staining. Result After acupuncture intervention, the RA rabbit knee joint circumference was shortened in all the equal reinforcement and reduction, twirling reinforcement, and heat reinforcing acupuncture manipulation groups, but the shortening effect on the RA rabbit knee joint circumference was better in the heat reinforcing acupuncture manipulation group than in the equal reinforcement and reduction and twirling reinforcement method groups (P<0.05);the inflammation score recorded according to the RA rabbit synovial histopathological sections was also decreased more in the heat reinforcing acupuncture manipulation group than in the equal reinforcement and reduction and twirling reinforcement method groups (P<0.05). Synovial LDH integral optical density, total positive area and area percentage were significantly higher in the model group than in the normal group (P<0.05), and significantly lower in the equal reinforcement and reduction, twirling reinforcement, and heat reinforcing acupuncture manipulation groups than in the model group(P<0.05) and also in the heat reinforcing acupuncture manipulation group than in the equal reinforcement and reduction and twirling reinforcement method groups (P<0.05). Rabbit synovial SDH and CCO activities were significantly higher in the model group than in the normal group (P<0.05). Rabbit synovial SDH and CCO integral optical density, total positive area and area percentage were significantly higher in the equal reinforcement and reduction, twirling reinforcement, and heat reinforcing acupuncture manipulation groups than in the model group (P<0.05) and also in the heat reinforcing acupuncture manipulation group than in the equal reinforcement and reduction and twirling reinforcement method groups (P<0.05). Conclusion Heat reinforcing acupuncture manipulation has a definite therapeutic effect on RA and can increase SDH and CCO activities to enhance aerobic metabolism and produce more local energy in a rabbit model of RA. That may be the mechanism by which heat reinforcing acupuncture manipulation produces heat.

Objective To investigate the diagnostic value of the split-hand sign in amyotrophic lateral sclerosis ( ALS).Methods Ninety ALS patients, 41 patients with other neuromuscular disorders and 71 normal controls were recruited for conventional nerve conduction study.Compound muscle action potential ( CMAP) amplitude recorded from abductor pollicis brevis ( APB) , abductor digiti minimi ( ADM) and first dorsal interosseous (FDI), CMAP amplitude ratios, CMAP amplitude differences and split-hand index ( SI) were analyzed.Results The APB/ADM CMAP amplitude ratio was significantly lower in the ALS patients (0.44(0.44)) than that in the patients with other neuromuscular disorders (1.31(0.87);z=6.967, P<0.01) and the normal controls (0.99(0.42);z=7.687, P<0.01).The FDI/ADM CMAP amplitude ratio was significantly decreased in the ALS patients ( 0.79 ( 0.46 ) ) compared with that in the normal controls ( 1.23 ( 0.39 ); z =5.899, P <0.01 ).The FDI/ADM CMAP amplitude ratio was comparable between the ALS patients and the patients with other neuromuscular disorders ( 0.93 ( 0.62 );z=1.737,P=0.081).SI was significantly lower in the ALS patients (2.42 (3.14)) than that in the patients with other neuromuscular disorders (10.10(6.54);q=7.947, P<0.05) and the normal controls (17.93(8.32);q=10.827, P<0.05).SI <5.2 can help differentiate ALS from mimic disorders, with a sensitivity of 83.33% and specificity of 96.43%.Conclusions The split-hand sign appears to be a specific feature of ALS.SI robustly differentiates ALS from mimic disorders and potentially facilitates an earlier diagnosis of ALS.

Aim To investigate changes of eosinophil(EOS) and mast cells(MC) in airway of young asthmatic rats and to evaluate of achyranthes bidentata polysaccharides(ABPS) on it.Methods Fifty Sprague-Dawley(SD) rats were randomly divided into five groups,ten rats per group:asthmatic group(A),control group(C),pretreatment groups with ABPS which was done according to three different schedules:consecutively 3 days at sensitization(T_1),at challenge(T_2) or both of the two periods(T_3).Asthmatic rats were induced by intraperitioneal sensitization and challenged with nebulized ovalbumin(OVA).Lungs were embeded in paraffine and sliced,Hematoxylin and eosin(HE) staind tobuidine blue restained and TUNEL method after animals were executed,then the quantity and degranulation phenomenon of EOS and MC and the apoptosis of EOS in airway were observed.Results ① The number of inflammatory cells and EOS in the airway was significantly increased in asthmatic group but reduced in group T_1 and T_3(P

Objective To study the effects of granulocyte-macrophage colony stimulating factor (GM-CSF) on the expression of vascular endotllelial growth factor (VEGF) in human dermal fibroblast. Methods In vitro human dermal fibroblasts in good status were incubated with GM-CSF (GM-CSF group) or non-GM-CSF (control group) culture medium for different periods of time. The mRNA, protein expression of VEGF in derma fibroblast were determined by reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting, respectively, and the secretion of VEGF in supernatant was measured by enzyme linked immunosorbant assay (ELISA). Results The expression of VEGF mRNA from dermal fibroblasts was increased significantly after l or more hours of incubation with GM-CSF comparing with the control (P＜0.05). 6 hours of stimulation by GM-CSF caused maximal expression of VEGF mRNA. The expression of VEGF protein in dermal fibroblasts was increased from 12 hours and was peaked at 24 hour after stimulation by GM-CSF. VEGF protein from the supernatant of the dermal fibroblasts was also raised persistently from 12 hour after stimulation by GM-CSF and was improved remarkably compared with the control. Conclusions GM-CSF can up-regulate directly the expression of VEGF in human derma fibroblast, which may be one of the mechanisms that GM-CSF accelerates neovascularization in wound healing.

Objective To observe the effects of buccal acupuncture therapy and body acupuncture therapy on plasma metabolomites of rheumatoid arthritis rabbits model; To search for the metabolites related to the mechanism of buccal acupuncture and body acupuncture. Methods Sixteen rabbits were made into rheumatoid arthritis models by complete freund's adjuvant before the treatment. The buccal acupuncture group was treated by buccal acupuncture on the knee acupoint; 13 mm × 0.32 mm needle straight 0.2–0.5 mm, twist the main points of stimulation 15 s, once a day. The body acupuncture group was treated by body acupuncture on the Xiyan and Zusanli acupoints; with 13 mm × 0.32 mm needle straight 2–3 mm, every 5 min each time, twisting needle method, 100 times/min for 15 s, once a day. After the continuous treatment for 5 days, UPLC-QTOF/MS was applied to test metabolite from the plasma sample of all groups. Similarity analysis, hierarchical cluster analysis (HCA), principal component analysis (PCA), orthogonal partial least squares-discriminant analysis (OPLS-DA) were applied in this research; meanwhile load analysis method was used to identify the meaningful metabolites. Results The similarity analysis, HCA and PCA all showed the significant difference of endogenous metabolites in plasma samples among the buccal acupuncture group, the body acupuncture, the model group and the blank group. The 4 groups of different plasma sample metabolite were completely separated in three dimensions by OPLS-DA and all the samples were gathered respectively. The load analysis indicated that there were 19 kinds of endogenous metabolites which showed the significant differences between buccal acupuncture group and model group, and also happened between the body acupuncture group and the model group; N-cetyl-L-phenylalanine and 2-phenyl propionate in metabolism of phenylalanine and tyrosine decreased significantly in the buccal acupuncture group while significantly increased in the body acupuncture group. Conclusion There are relative similarity on the mechanism of treating rheumatoid arthritis between buccal acupuncture and body acupuncture. However, N-acetyl-L-phenylalanine and 2-phenyl propionate, as the main potential biomarkers of the difference, indicate that the dissimilarity can be significant.

ObjectiveTo evaluate the biocompatibility of a kind of scaffolding material,Injured Nerve Regenerated Materid(INRM), which play the roles of regeneration of nerve after traumatic brain injury.MethodsINRM scaffolding material were transplanted into cortex of rats after traumatic injury.The brain coronal sections were stained for Nissel, astrocyte and microglia at 1 week, 1 month, and 2 months after injury.ResultsThe presence of INRM did not alter patterns of astrocyte compared with the control group (detected with antibodies against GFAP) at any time point; but decreased the expression of microglias (detected with antibodies against OX42) compared with the control group.ConclusionThe biomaterial INRM is well suited as a biocompatible scaffold material for the repair of brain injury in the brain.

Objective To explore the role of ubiquitin-proteasome pathway for the gelsolin protein degradation in pancreatic cancer.Methods Pancreatic cancer cell lines BxPC-3 and PANC-1 were first treated with specific 26s proteasome inhibitor lactacystin.Immunoblots of cell lysates were probed for gelsolin expression.To determine whether gelsolin was conjugated to ubiquitin,proteins extracted from the cells with or without lactacystin were immunoprecipitated with anti-gelsolin antibody,followed by Western blot analysis.Results The expression of gelsolin protein increased obviously after treatment with lactacystin in BxPC-3 cells for 12 h.Using anti-gelsolin antibody to immunoprecipitate gelsolin protein and followed by Western blot using anti-ubiquitin monoclonal antibody,it was found that inhibition of proteasome pathway by lactacystin resulted in accumulation of ubiquitylated forms of gelsolin protein.In PANC-1 cell line,there was no significant changes of gelsolin after treatment with lactacystin.Conclusion Ubiquitin-proteasome dependent degradation may be an important regulatory mechanism for gelsolin down-regulation in pancreatic cancer cells.
