Objective To investigate the effect of antisense oligodeoxynudeotides(ODN)targeting nuclear factor ?B(NF-?B)on the expressions of Caspase-3 and NF-?B in glomerulosclerosis.Methods Male SD rats were divided into 3 groups:sham operation(group A,n=6),glomerulosclerosis(group B,n=6),intervention(group C,n=9).Group C was divided into 3 groups:sense ODN(group C1,n=3),non-sense ODN(group C2,n=3),antisense ODN(group C3,n=3).Glomerulosclerosis models were made for SD rats by unilateral nephrectomy and being injected with adriamycin into caudal vein.After 8 weeks,various ODN applied to corresponding group for intervention.At the end of the 9th week,kidneys were taken out from all rats for the measurement of expressions of NF-?B p65 and Caspase-3 by immunohistochemistry staining.Results After intervention,on the d7,the rats urine protein,glomerular sclerosis index(GI)and expressions of Caspase-3,NF-?B p65 in group C3 were significantly lower than those in group B,C1,C2(Pa0.05).Conclusion Antisense ODN targeting NF-?B can inhibit the activities of NF-?B,Caspase-3 in rats kidneys and retard glomerulosclerosis and glomerular intrinsic cell apoptosis.

Objective To investigate the association of the Glu298-Asp(894G→T)mutation at exon 7 of the endothelial nitric oxide synthase gene and acute myocardial infarction.Methods By using the designed primers based on flanking sequences of the Glu298-Asp mutation at exon7 of eNOS, 894G→T fragments were amplified by nested PCR from genomic DNA of healthy control and AMI subjects, digested by restriction enzyme after amplification and detected by agarose gel electrophoresis for 894G→T genotyping. To count the genotype and allele frequencies, the significance of difference in the genotype and allele between two groups were assessed by statistical analysis.Results Three genotypes containing GG, GT, TT were identified on the 894 site of the eNOS gene exon 7 in both AMI and controls. In AMI group, there were 25 patients having 9 homozygotes, the other 16 having heterozygotes. In controls, there were 13 cases with G894T mutation,all having heterozygotes. The mutation frequency of TT homozygote allele has extraordinary significant difference between two groups (P

The disadvantages of Admas clasp include inconvenient manual adjustment and being unsuitable to the deciduous molars.The modified Admas clasp can overcome the shortcomings.

The mesially impacted of mandibular second molar is one kind of common malocclusion in clinic.It can lead to damages to stomatognathic system.The looped uprightor is an effective tool in the treatment of this kind of malocclusion.

OBJECTIVE:To evaluate the effects of PDCA cycle management method on clinical application of Fat-soluble vita-min for injection (Ⅱ). METHODS:By retrospective analysis,500 discharge medical records of Fat-soluble vitamin for injection (Ⅱ)were collected from our hospital during Jul.-Aug. in 2015(before intervention),Sep.-Oct. in 2015(after first intervention cy-cle),Nov.-Dec. in 2015(after second intervention cycle),respectively. RESULTS:After 2 PDCA cycles,the proportion Fat-solu-ble vitamin injection (Ⅱ) use without indication decreased from 65.4% to 39.2%;the reasonable rate of drug dosage increased from 53.2% to 97.2%,and that of usage increased from 96.4% to 99.8%;the reasonable rate of medication course increased from 69.6% to 96.6%;the reasonable rate of the clinical application of Fat-soluble vitamin injection (Ⅱ) increased from 18.8% to 56.4%,with statistical significance (P<0.05). CONCLUSIONS:PDCA cycle can effectively promote the clinical reasonable of Fat-soluble vitamin for injection(Ⅱ).

With the change of medical mode and deepening of the medical education reforms,such educational idea as giving prominence to practice is widely used to improve students' comprehensive quality and innovative ability and practice ability. The medical shool of Tibet university has established long-term apprentice mechanism during the before class and playtimes and found four county hospitals, five health clinics in towns and townships and gradually improved the construction of mutual win-win 9clinical teaching bases. In this way it has been cultivating many advanced medical personnels, who are reliable, available, able to stay, and highly praised by the employers.

The buccoversion malpositon of maxillary second molars is one kind of common malocclusion.It can lead to damages to stoma-tognathic system.The adjustable maxillary molar retractor is an effective tool in the early treatment of this kind of malposition.

Objective To evaluate CT and MRI features of brain lesions in CO poisoning and to compare the ability of detecting rate of lesions by CT and MRI.Methods CT and MRI appearances in 52 cases with CO poisoning were analysed and compared.Results Necroses and degenerations of globus pallidus in 9 cases,cerebral white matter demyelination in 3 cases and brain atrophy in 3 cases were showed by CT.The detecting rate was 28.8% by CT while,necroses and degeneration of glodus pallidus were observed in 24 cases and white matter change in 7 cases were observed by MRI,the detecting rate was 59.6% which was higher than that of CT (?
