OBJECTIVETo explore the distribution features of Chinese medical syndromes of rheumatoid arthritis (RA) by literature retrieval.

METHODSPertinent articles on treating RA by syndrome differentiation were retrieved from China National Knowledge Infrastructure Databases (CNKI), VIP Chinese Biomedical Journal Database, Guizhou Digital Library, and Duxiu Chinese Academic Periodicals full papers database from January 2000 to December 2011.

RESULTSA total of 33 documents were recruited covering 4 233 cases. Damp-heat blocking collaterals syndrome occupied the top in the occurrence frequency (20 times, 60.61%), followed by deficiency of Gan and Shen syndrome (18 times, 54.55%), intermingled phlegm and blood-stasis syndrome (17 times, 51.52%), wind-cold-damp impediment syndrome (15 times, 45.45%), cold-damp blocking collaterals syndrome (14 times, 42.42%), wind-damp-heat impediment and deficiency of qi and blood syndrome (10 times, 30.30%), and intermingled cold and heat syndrome (9 times, 27.27%). According to the case number of patients, it was sequenced as damp-heat blocking collaterals syndrome syndrome (768 cases, 18.14%), wind-damp-heat impediment syndrome(666 cases, 15.73%), wind-cold-damp impediment syndrome(584 cases, 13.80%), cold-damp blocking collaterals syndrome syndrome (517 cases, 12.21%), intermingled cold and heat syndrome (415 cases, 9.80%), intermingled phlegm and blood-stasis syndrome (364 cases, 8.60%), deficiency of Gan and Shen syndrome (235 cases, 5.55%),asthenia of healthy energy due to lingering arthralgia syndrome (223 cases, 5.27%). The case numbers of remaining syndromes did not exceed 5%.

CONCLUSIONDamp-heat blocking collaterals syndrome was the main syndrome in RA patients, followed by wind-cold-damp impediment syndrome,wind-damp-heat impediment syndrome,cold-damp blocking collaterals syndrome,intermingled phlegm and blood-stasis syndrome, and deficiency of Gan and Shen syndrome.

Objective To investigate lipopolysaccharide (LPS) tolerance and its possible mechanism in experimental acute pancreatitis(AP) mice. Methods Two hundreds and ten C56BL/6J mice were randomized into normal saline(NS)+LPS group( n =105)and AP +LPS group( n =105). Both groups were subdivided into seven groups according to different dose of LPS. AP model was induced by intra- abdominal administration of cerulein (50 ?g/kg) for seven times at 1 hour interval. LPS was given 6 hours after first cerulein injection . Cerulein was replaced by NS in NS+LPS group. Ten mice in each sub- group were randomly selected to investigate mortality rate for 7 days. Another 5 mice were killed at 12 hours after the first cerulein injection. Liver, lung, kidney, pancreas and serum were reserved to evaluate pathological changes and measurement of amylase (AMS) and lactate dehydrogenase (LDH) levels. Gene expression profiles of leucocyte in NS+LPS(15 mg/kg)subgroup and AP+LPS(15 mg/kg)subgroup were studied with oligonucleotide microarrays of 12 479 full length mouse genes respectively for three times to screen the different genes between two groups. Results Mortality rates in both groups were increased, and correlated with the dosage of LPS. Mortality rate in AP+LPS group was significantly lower than that in NS+LPS group with the same LPS dose( P

Objective To investigate the effects of oxidized 1-palmitoyl-2- arachidonoyl-sn- glycero-3-phosphorylcholine (OXPAPC)in LPS signal pathway and acute necrotizing pancreatitis (ANP).Methods Eighty-eight SD rats were randomly divided into two groups:ANP group and ANP treat with OXPAPC group.ANP model was induced by injecting sodium taurocholate(5%)into pancreatic duct OXPAPC group was administered with OXPAPC at 0 hours and 6 hours after model establishment.Twenty rats from each group were separated to observe mortality.The others were killed at 12 hours,24 hours,48 hours and 72 hours respectively to detect serum levels of amylase and lactate dehydrogenase (LDH).Severity of pancreatitis was evaluated by histological score system.The activity of myeloperoxidase (MPO)in pancreas was determined by zymohistochemistry.Inflammatory factors mRNA hours after treated with OXPAPC were studied by semi-quantitative RT-PCP.Intracellular proteinase were investigated by western blot.EMSA was used to testify the activity of transcriptional factors.Results The mortality in OXPAPC group was significantly than that in ANP group. Serum amylase and LDH levels at significanfiy decreased the 12 hours and 24 hours after treated with OXPAPC.Histologically,OXPAPC reduced the severity of pancreatic injury including inflammatory cell infiltration and necrosis at 12 hours,24 hours,and 48 hours.There was a significant decrease of MPO activity in OXPAPC group compared to ANP group.Levels of inflammatory factors mRNA were reduced in OXPAPC group.Intracellular proteinase were down-regulated in OXPAPC group.EMSA showed that the activity of transcriptional factors weakened.Conclusion OXPAPC can block LPS signal pathway,so it can decrease the severity of ANP.

Objective To establish a mouse model for scleroderma.Methods Forteen BALB C and 14 C3H female mice were averagely divided into model 1 and controls.Daily 0 1 ml BLM at a concentration of 200 ?g/ml was injected intracutaneusly into the backs of model 1 mice for 3 weeks,and 0 1 ml solution of PBS were injected intracutaneusly into the backs of control mice for 3 weeks.Observing the histological change of skin and lungs was made and measuring the thickness of dermis was performed with a medical analysis system of the color picture,determined the collagenic quantity was done with photoelectric colorimetry,and calculating the immunohistochemical index of collagen type Ⅰ and Ⅲ and transforming growth factor ? 1 (TGF ? 1) in the skin lesions from the mouse model and control was done.SPSS was used to finish the statistical analysis of the detective value from model 1 and controls.Results In the skin of model mice,the thickness of dermis markedly thickened ( P

AIM: To establish the determination of baicalin and wogonin in Chantui Zhike Granules (Periostracum Cicadae, Radix Scutellariae, etc.) by HPLC. METHODS: The determination was carried out by HPLC. The mobile phase was acetonitrile 0.6% phosphoric acid(45∶55) and UV detection wavelength was set at 275nm. The flow rate was 1.0mL?min -1 . The column temperature was at 40 ?C . RESULTS: The contents of baicalin and wogonin in Chantui Zhike Granules could be determined by HPLC. There was a good linearity between the absorption peak area and the concentration in the range of 0.104?g～0.52?g for baicalin and in the range of 0.03?g～0.15?g for wogonin, respectively. The average recoveries were 100.69%( RSD =1.75%) and 98.8%( RSD =1.01%) respectively. CONCLUSION: The method is simple, accurate and can be used to determine the contents of baicalin and wogonin in Chantui Zhike Granules.

Objective To explore the functional impairment characteristics of acute stroke patients and cor- relate them to the functional independence after rehabilitation therapy. Methods Seventy-nine inpatients with stroke were divided into hemorrhage group and infarct group according to their condition.They are assessed by using measures of ESS,MBI,MMSE,Sheikh,Fugl-Meyer Balance and Fugl-Meyer motor assessment before rehabilitation treatment.After 1 month of treatment,all the patients were evaluated again using FIM.Correlation analysis was con- ducted with all the parameters. Results It was found that patients in the hemorrhage group scored lower with MBI, Sheikh,Fugl-Meyer Balance and FIM than those in the infarct group (P

Aim To investigate the intraspecific variation of Carthamus tinctorius L. (safflower) and establish foundation for further breeding of safflower germplasm resource and screening the quality correlation genes. Methods Amplified fragment length polymorphism (AFLP) was carried out to analyze genetic variation of 28 safflower populations collected in China. Unweighed pair-group method of with arithmetical averages (UPGMA) cluster analysis was used to construct a dendrogram and to estimate the genetic distances among the populations. Results All populations could be uniquely distinguished using 12 selected primer combinations. Similarity coefficients ranged from 0. 48 to 0. 96 among the populations.Dendrogram revealed distinct segregation of all the cultivars into three main groups and one midst group.Conclusion Limited genetic diversity exists within the tested 28 collections at intra specific level and AFLP-based phylogeny was not absolutely consistent with that based on morphological characters may be due to the interaction effect between genotype and environment.
