Objective To investigate the relation of the expressions of matrix metalloproteinase-2(MMP-2)and-9(MMP-9)with polymyositis/dermatomyositis(PM/DM).Methods Blood samples were obtained from 8 patients with PM,12 patients with DM and 10 normal human controls.Real-time quantitative RT-PCR and Western-blot were applied to examine the mRNA and protein expressions of MMP-2 and MMP-9 respectively in the peripheral blood mononuclear cells(PBMC)of these patients.Results The mRNA expression levels of MMP-2 and MMP-9 in the PBMC of patients with PM or DM were 2.41 and 1.66 folds as high as those of the normal controls,respectively;these difierences were significant between the two groups.Increased expressions of MMP-2 and MMP-9 were also noted in the patients with PM or DM.Conclusion MMP-2 and MMP-9 may play a part in the development of polymyositis and dermatomyositis.

In the past few years,it has been disclosed that identified epigenetic processes and epigenetic changes are involved in human diseases.Disorders of these processes may influence chromatin structure and gene expression,which may result in complicated syndroms,multiple-factor diseases and cancers. The researchprogress of epigenetic processes of several diseases is reviewed in this paper.

The changes of rheobase(Rh), chronaxie(Chr), standard electrical quantity(a) and mtensity-duration curve(i. t. c) were studied for understanding the effect of aging on the excitability of sciatic and caudal nerves in Wistar rats of different age. The results show that before grown-up excitability of the peripheral nerves increases progressively with age, after that it tends to decrease. Chronaxie as an index can not reflect the change of excitability of the peripheral nerves correctly.

Objective To evaluate the power of the PowerPlex?6 system for paternity testing. Method 633 cases of paternity testing were studied. After the megaplex STR amplification, the PCR products were genotyped by using the ABI377 DNA Sequencer. Results Among the 879 unrelated individuals, 197 alleles and 739 different genotypes were observed. The cumulated discriminating power was 1x 10-30. And the cumulative chance of exclusion was 0.999999999999987. 95 out of 633 cases were excluded. The RCP of all unexcluded cases were ≥0.9990. Gene mutations were found in 19 cases. Conclusion The Po-werPlex?16 system is powerful and reliable for paternity testing.

0 05).Among the 13 patients with liver damage,AKP and ? GT were raised in 6,and AKP,? GT,TBIL and DBIL all elevated in 4 In 8 patients anti SMA and AMA were detected,and 5 showed AMA positive.Liver biopsy in 6 patients showed 3 with chronic active hepatitis among which 2 were complicated with liver cirrhosis,1 chronic persistent hepatitis and 2 cholangitis.Of the 6 patients 5 showed different degrees of infiltration of mononuclear cells in the portal tracts.Conclusion The occurrence of liver damage in pSS is rather high.The liver damage may be related to primary biliary cirrhosis (PBC).Patients′ response to corticosteroid treatment is favourable and their prognosis appears good.

Objective To compare the effects of different doses of dexmedetomidine on postoperative analgesia and sedation.Methods From January 2014 to November 2015,60 cases who needed postoperative analgesia and sedation in our hospital were selected.According to the dosage of dexmedetomidine,they were divided into control group and observation group,30 cases in each group.Two groups of patients were given analgesia pump for analgesia, with 0.5μg·kg-1·h-1,1.0μg·kg-1·h-1 two doses of dexmedetomidine,and analgesia 48 h.At different time points,the VAS pain score,Ramsay sedation score of the two groups were compared,the calm satisfaction in both two groups was recorded,the average incidence of delirium and delirium score in the process of the treatment and the occurrence of adverse reactions were observed.Results With the extension of time of postoperative analgesia,VAS scores in each group decreased,VAS scores in the observation group after 4h,8h,12h were (3.01 ±0.53)points, (1.95 ±0.58)points,(1.52 ±0.35)points,which were lower than those of the control group[(3.92 ±0.32)points, (2.86 ±0.67)points,(2.25 ±0.78)points],the differences were statistically significant (t=3.42,4.11,2.43,all P<0.05).After 24h,48 h,VAS score between the two groups had no significant difference(P>0.05).Postoperative 4h Ramsay score between the two groups had no significant difference (P >0.05 ).With increased postoperative analgesia time,Ramsay scores in two groups decreased,postoperative 8h,12h,Ramsay scores in the observation group [(2.95 ±0.83)points,(2.22 ±0.55)points]were lower than the control group[(3.76 ±0.78)points,(2.98 ± 0.89)points,t=3.45,2.38,all P<0.05].Postoperative 24h,48 h,the Ramsay scores between the two groups had no significant difference(P>0.05).The sedation satisfaction of the observation group (96.67%)was higher than the control group (86.67%),the incidence rate of delirium and delirium average score [3.33%,(15.11 ± 2.03)points]were lower than the control group[13.33%,(19.23 ±2.21 )points],the differences were significant between the two groups (t =4.32,4.32,3.27,all P<0.05 ).After treatment,the adverse reactions were mainly bradycardia,nausea,vomiting,drowsiness,respiratory depression,urinary retention.The overall incidence rate of adverse reactions between the two groups had no significant difference (P >0.05 ).Conclusion The effect of 1 .0μg·kg-1 · h-1 concentration dexmedetomidine within 24h of postoperative analgesia sedative is best,it can reduce the incidence of postoperative delirium,and without obvious drug side effects.
