Objective To survey the relationship between myocardial damage of chronic and latent Keshan disease with A360P missense mutation in desmin gene exon6. Methods By clinical epidemiology method,30 cases had been collected randomly among chronic Keshan disease patients and 30 cases equally among healthy adults (inner control groups) in Diantou town,Huangling county,Shaanxi province,a Keshan disease area,and 30 cases among health adults(outer control group) in Chang'an district,Xian city,a normal area. Genome DNA had been extracted from 90 blood samples. Different restriction sites had been analyzed by the methods of PCR,digested by restriction endonuclease and electrophoresis. By virtue of Bsp1286 Ⅰ enzyme,122 bp and 60 bp strap could be found in control group from exnn4,showing that Bsp1286 Ⅰ enzyme was active. By virtue of Bsp1286 Ⅰ enzyme,desmin gene exon6 was digested to 184 bp and 66 bp strip when A360P missense mutation site exited in exon6. Results One hundred and twenty two bp and 60 bp strap could be found in control group from exon4 digested by Bsp1286 Ⅰ ,which showed Bsp1286 Ⅰ enzyme was active. Two hundred and fifty bp strips can only be found in digest products of exon6. One hundred and eighty-four and 66 bp strips which were the products of DNA digested by Bsp1286 Ⅰ could not be found. A360P missense mutation site of desmin gene exon6 had not been found among chronic and latent Keshan disease patients and tow control groups in Keshan disease area and in normal area. Conclusions A360P missense mutation site of desmin gene exon6 has not been found among chronic and latent Keshan disease patients. A360P missense mutation of desmin gene exon6 probably is not predisposing genes of chronic Keshan disease.

Objective To observe the dynamic levels of IL-2,IL-5 and IL-6 produced by Balb/ c mice infected with DEN_2 clinical strains and to study their relation.Methods The Balb/c mouse in- feetion model was established by multiple-site subcutaneous injection with various doses of DEN_2 clini- cal strain.Mouse plasma samples collected from different experiment groups at various time after in fection were tested for IL-2,IL-5 and IL-6 levels with sandwich ELISA.Results After primary in- feeted with DEN_2 B strain,the levels of IL-2,IL-5 and IL-6 of all experimental groups were not sig- nificantly higher than the normal control group while the levels of experimental groups increased sig- nificantly after re-infection.The level of IL-2 reached to peak[average value of(101 522.44?10 465.375)pg/ml]at the 4th day after re-infection(the 20th day after the primary infection),and then the level gradually reduced.The levels of IL-5 in the Balb/c mice of the group 1 and 2 reached to peak at the 1st day after re infection(the 16th day after the primary infection),and there was signifi- cant difference between these two groups and the control group(P＜0.05).The levels of IL-6 in all experimental groups reached to peak at the 1st and the 2nd day after re-infection.The peak value of the third group is the highest comparing with the normal control group(P＜0.05).Conclusion Th2 response was predominant in the second infection phase.

The influence of ?-ionone and ergosterol on the growth and the yield of CoQ_ 10 in yeast was investigated. The results indicated that ?-ionone had the stimulative effect on the biosynthesis of CoQ_ 10 in yeast, and 28.3% increase of the CoQ_ 10 content in the cell was observed when the concentration of ?-ionone in the medium was 0.208?10~ -3 mol/L. Little ergosterol also had the same effect with ?-ionone, while 31.3% increase of the CoQ_ 10 content in the cell was observed when the concentration of ergosterol in the medium was 0.15?10~ -4 mol/L. However, the biosynthesis of CoQ_ 10 was inhibited when the concentration of ergosterol was 0.60?10~ -4 mol/L. Addition of ?-ionone and ergosterol to the medium resulted in 36.1% increase over the control. The results showed that the cell could effectively accumulate more CoQ_ 10 with the addition of ?-ionone and ergosterol to the medium.

Objective To investigate the process of apoptosis in lungs and liver induced by crushing hindlimbs of rat, and study the mechanismof crush injury. Methods The rat experimental model of hindlimbs crush injury was established. The cell apoptosis in lungs and liver was detected by TUNEL assay, and the expression of Bax, Bcl-2 and caspase-3 apoptin was examined by immunohistochemistry. Results C ompared with the control group, the partial muscle injury of rat’s hindlimbs was more serious with more apoptosis observed in lungs and liver (P<0.05). The expression of Bax was up-regulated and Bcl-2 was down-regulated, whereas caspase-3 expression was activated (P<0.05). Conclusion The cell apoptosis has increased significantly in lungs and liver after crush injury of hindlimbs in rat. The corre-lation factor released during tissue injury may mediate apoptosis process.

To study the value of high-fluorescent cell for the screening of malignant hydrothorax or ascites. The clinical diagnosis results and hydrothorax or ascites specimens of 400 outpatients registered from January to December in 2014 were collected, and high-fluorescent cells were counted with Sysmex XE-5000 blood cell analyzer, and then stained for microscopy. Receiver operating characteristic (ROC) curve was used to explore the sensitivity, speci-ficity, positive likelihood ratio and negative likelihood ratio of high-fluorescent cell for screening malignant hydrothorax or ascites. The numbers of high-fluorescent cells of the cancer patients were significantly higher than those of the non-cancer patients, with Z equal to -7.372 and P less than 0.05. The values of the area under curve (AUC), sensitivity, specificity, positive likelihood ratio and negative likelihood ratio were 0.801, 70.67%, 84.31%, 4.50 and 0.35 respective-ly. Detection of high-fluorescent may be used to screen malignant hydrothorax or ascites, and further exami-nation and follow-up have to be performed in case the number of high-fluorescent cells in the hydrothorax or ascites is not less than 68.
