Objective To investigate the association between systemic lupus erythematosus(SLE) and polymorphism of cytotoxic T-lymphocyte antigen 4 gene(CTLA-4) and the effect on ANA and anti-dsDNA antibody.Methods The A/G substitution was investigated in the exon 1 position 49 in 92 SLE patients and 60 controls by PCR restriction fragment length polymorphism(PCR-RFLP).ANA and anti-dsDNA antibody were examined by indirect fluorescence immunoassay.Results SLE patients had significantly higher frequencies of the CTLA-4+49GG allele than controls(P

Objective To explore the reasonable experimental parameters on establishment of rabbit model of infusion phlebitis induced by mannitol.Methods New Zealand rabbits were injected with 20％ mannitol,then pathological lesion of rabbit auricular vein induced by different infusion velocity,different sampling time and sites were observed under microscope with vascular injury,inflammatory cell infiltration,frequency of thrombokinesis as indexes.Results The three indexes were the highest and the most obvious characteristics of infusion phlebitis were noted at the following experimental conditions:5.0 ml/min (infusion velocity),sampling time at 24h after administration and sampling site at 1cm region in front of the catheter tip.Conclusions Rabbit model of infusion phlebitis induced by mannitol can be set up more stable by using these parameters.

Objective To provide molecular genetic basis for oncobiological difference in left sided colon cancer and right sided colon cancer. Differentially expressed proteins in left sided colon cancer and right sided colon cancer were screened by proteomic technique. Methods Tissue samples including left sided colon cancer and right sided colon cancer were collected and preserved in the -80℃ refrigerator. In the first part of our experiment, protein was separated by 2-dimensional gel electrophoresis (2-DE) and the images of the gels were acquired by the scanner and then analyzed to find the differentially expression protein-spots in different groups. The peptide mass fingerprintings (PMF) was acquired by matrix assisted laser desorptiorn/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and the proteins were identified by data searching in the Mascotdatabase. Differentially expressed proteins were assayed by RT-PCR, Western blot, and immunohistochemical method. Results Altogether 55 differentially expressed protein spots were screened and 21 spots of them were identified. Compared with the right sided colon cancer, 14 proteins were up-regulated and 7 proteins down-regulated including HSP27 in the left sided colon cancer. HSP27 expressed higher in the right sided colon cancer than in the left sided colon cancer.Conclusion There are differentially expressed proteins in left sided colon cancer and right sided colon cancer, especially difference in HSP27 expression at mRNA and protein level, which may be molecular genetic basis for oncobiological difference in left sided colon cancer and right sided colon cancer.

This study was aimed to investigate the antitussive,expectorant,antiasthmatic and anti-inflammatory effect of Ju-Hong Tan-Ke (JHTK) liquid.The methods of cough induced by ammonia in mice and cough induced by citric acid in guinea pigs were used to observe the antitussive effects.The mouse phenolsulfonphthalein excretion method,rat capillary expectoration method and the rabbit tracheal cilia movement influence experiment were used to observe the expectorant effect.An experiment of allergen induced rats' asthma was used to observe the antiasthmatic effects.The anti-inflammatory effect was observed by mouse peritoneal capillary permeability test and xylene induced ear swelling in mice.The results showed that JHTK liquid could inhibit cough induced by ammonia in mice,decrease the frequency of cough induced by citric acid in guinea pig and prolong the latent period of cough.The medicine could also obviously increase phenol red output of trachea in mice,promote expectoration in rats,accelerate the movement of cilium of tracheal transparently and prolong the latent period of asthma induced by allergens in rats,inhibit capillary permeability and lighten ear edema in mouse model.It was concluded that JHTK liquid could inhibit the reflex cough caused by hypersensitivity of airway sensor.It is peripheral antitussive rather than central antitussive,which has significant antitussive,expectorant,antiasthmatic and anti-inflammatory effects.Its efficacy is superior or equivalent to positive chemical control medicine.

Objective To explore the spatial description of Keshan disease(KD)and to provide a basis for reasonable allocation of health resources and for making precision prevention and control strategies. Methods In 2013 and 2014, the KD's condition, prevention and control measures and their effects were investigated in the diseased affected counties in the provinces through combination of case search and key survey. Results A total of 16(100.0%,16/16)diseased provinces,315(96.0%,315/328)diseased counties were surveyed,and 1 562 people with KD were detected in 281 000 residents, the detection rate was 55.6/10 000. Chronic and latent KD detection rates were 8.9/10 000(250)and 46.7/10 000(1 312),respectively.There were 261(82.9%)diseased counties that had reached the control standards of KD,and 54(17.1%)did not meet the control standards,which mainly distributed in the provinces of Henan, Inner Mongolia, Gansu and Shanxi. Conclusions The detection rate of KD has been at a low level, but in Henan, Inner Mongolia, Gansu, and Shanxi, there are prevalent KD areas that have not yet reached the control level.This part of the areas should be treated as key prevention and control areas of KD.

Objective To explore the spatial distribution clustering and influencing factors of chronic Keshan disease in China,and to provide evidence for prevention and control of Keshan disease.Methods Using non-probability sampling methods,combined with case search and key surveys,data on national detection rate of chronic Keshan disease,on disease influencing factors in 2013-2014 were collected;a spatial database was established,and ArcGIS 9.0 software was used to perform global Moran'sI,local Moran's I,local Getis-Ord Gi and inverse distance weighted interpolation analysis for the detection rate of national chronic Keshan disease.Spatial regression was used to analyze the influencing factors of chronic Keshan disease.Results Global autocorrelation analysis showed that Moran's I =0.03,Z =2.72,P ＜ 0.01,indicating that there was aggregation in the detection rate of Keshan disease.The results of local Moran's Ii showed that there were local high-detection rate clusters in the wards of Keshan disease,and the high-high aggregation areas were mainly concentrated in the wards of Gansu,Inner Mongolia,and Shanxi;the high-low aggregation areas were mainly located in the wards of Heilongjiang,Jilin,Shandong;the low-high aggregation area were mainly located in the wards of Heilongjiang.Getis-Ord Gi autocorrelation results showed that Keshan disease hotspots were mainly located in the wards of Inner Mongolia,Heilongjiang,Gansu,Shandong,Shanxi and Yunnan;the results of reverse distance weighted interpolation showed that the detection rates of the counties in Gansu and Inner Mongolia were higher than that in Heilongjiang,Jilin,Liaoning,Shanxi,Shandong,Shaanxi and Yunnan,the detection rate of wards in other provinces was at a lower level.Spatial regression analysis showed that the spatial distribution of chronic Keshan disease was negatively related to rural per capita net income and annual average temperature in the ward (Z =-2.808,-2.747,P ＜ 0.05).Conclusions Global chronic Keshan disease exists spatial aggregation,the local gathering area is mainly located in the wards of Gansu,Inner Mongolia.The spatial distribution of chronic Keshan disease may be affected by the level of rural per capita net income and annual average temperature in the ward.
