Delirium is a common complication after acute stroke.It usually indicates the poor outcome,higher mortality,longer hospital stay and increased dementia risk of patients.Therefore,the early detection and intervention of delirium after acute stroke have an important significance.This article reviews the pathogenesis,risk factors,diagnosis,assessment,treatment and outcome of delirium after stroke.

Iatrogenic vertebral artery injury is a rare complication in cervical spine surgeries,the consequences of which may be catastrophic.With the extensive development of cervical spine surgeries and application of diverse new internal fixations of cervical spine,there is a potential increase of risk of iatrogenic vertebral artery injury,which should be paid attention to.This article reviews the rate,cause and management etc.of iarogenic vertebral artery injury.

The designs, making the curer reliable and stable, prove practical.

0.05).Conclusions Plasma fibrinogen level is affected by -148C/T polymorphism of ?-fibrinogen gene. High plasma fibrinogen level is a risk factor for ACI in Chinese young adults. With other risk factors and environmental factors, T allele increases plasma fibrinogen level and may be a heritable risk factor for ACI in Chinese young adults.

Objective To evaluate preoperative bronchial atery infusion(PBAI) chemotherapy combined with surgery for patients with stage III A non-small cell lung cancer(NSCLC). Methods Seldinger procedure was used to insert the tube to bronchial artery branch which supplied blood to the tumor. The chemotherapeutic drugs were infused through the tube. After 1～3 courses of PBAI chemotherapy, the patients received operation. The patients receiving surgical treatment without PBAI chemotherapy at the corresponding period were chosen as control group. The radical resection rate and survival rate of the two groups were analyzsed. Results The response rate (CR+PR) of PBAI chemotherapy was 66.8%, and radical resection rate (90.3%) in PBAI chemotherapy group was significantly higher than that in control group(61.1%,P

Cognitive impairment in diabetes ( CID) is one of the complications of diabetes .The features of mild or moderate cognitive disorder and the decread abilities in memory and studying are the main symptoms of CID .But it′s mechanism is still un-known .NF-κB is the original signal activator , it can activate other signal pathway of cell dysfunction .With the influence of hyperglyce-mia and oxidative stress, the expression of NF-κB is enhanced, that leads to the changes of the expression of NOS , MMP-9, TNF-α, then, these changes lead to the apoptosis of hippocampus neuron cell .This review focuses on NF-κB in order to provide evidences in studying CID by reviewing the relationship between NF-κB and it′s relative factors of NOS, MMP-9, TNF-αand CID.

Objective:To determine the prevalence of Salmonella paratyphi C phage ( SPC-P1 ) in dif-ferent Salmonella serovars and to identify the integration sites in host genome. Methods: Based on the complete genome of SPC-P1 in S. paratyphi C RKS4594, 6 pairs of primers were designed and used to amplify the fragments of SPC-P1 in 11 S. typhi, 11 S. paratyphi A, 12 S. paratyphi B and 23 S. para-typhi C strains. At the same time, 100 complete genomes of Salmonella including 20 serovars available in National Center for Biotechnology Information ( NCBI) database were downloaded and aligned by Mauve 2. 3. 1 to determine the prevalence of SPC-P1 in these serovars. Primers were designed according to the integration sites of SPC-P1 in the genome of RKS4594 , and used to amplify ten strains having SPC-P1 in the genome. The PCR products were sequenced to investigate the integration sites of SPC-P1. Results:SPC-P1 was widely distributed in S. paratyphi C genome. In the study, 14 strains had all 6 fragments and 2 strains had 3-5 fragments. All the amplified fragments showed expected sizes. In contrast, in the ge-nomes of S. typhi, S. paratyphi A and S. paratyphi B, no or only 1-2 fragments could be amplified, and the sizes were smaller than expected. The results from Mauve showed that only in the genome of S. choleraesuis, which was a close relative of S. paratyphi C, there existed an almost complete genome of SPC-P1. The insertion site of SPC-P1 in all the ten S. paratyphi C strains tested was between pgtE and yfdC genes. Conclusion:SPC-P1 is a unique virulence factor of S. paratyphi C. It may play roles in the host range and pathogenicity of S. paratyphi C.

Objective To study the relationship among iron metabolism indicators in the patients with hepatitis B and to analyze their clinical significance.Methods Serum ferritin,iron and hepcidin were detected in 96 cases of hepatitis B and 58 negative control subjects.The above indicators detected results and their relationship were analyzed.Results Compared with the control group,ser-um ferritin and serum iron concentration in the hepatitis B group were increased,he difference was statistically significant (P <0.05);serum ferritin and serum iron concentration in the hepatitis B group demonstrated the positive correlation (P <0.05);serum ferritin in the patients with hepatitis B was negatively correlated with hepcidin (P =0.018).Conclusion The patient with hepatitis B often have the iron metabolism abnormality,and the iron metabolism indicators is expected to be an assessment indicator of treat-ment and prognosis in the patients with hepatitis B.

The serum manganese, chromium, zinc and copper levels of 63 cases with coronary heart disease and 33 normals were determined by the inductively couple plasma emission spectroscopy. The concentrations of Mn, Cr, Zn and Cu were 0.02145 ?0.0107 ppm, 0.0230 ?0.0167 PPm, 0.905?0.278 ppm 1.056 ?0.404 PPm and the Cu/Zn ratio was 0.973 ?0.395 in normals.In comparing with normals, a significant increase in the serum zinc concentration (P

Objective To study the effect of the polymorphism of (AC) n of aldose reductase (AR) gene on the erythrocyte AR activity in type 2 diabetes mellitus (DM). Methods One hundred and sixty three cases of type 2 DM and forty two controls were included in this study. The subjects were devided into DM without diabetic microangiopathy (DMAP) (NDC) (66 cases), DMAP groups (97 cases), and normal controls (CON) (42 cases); further, according to the type of allele, the subjects were devided into DM with Z+2 (DZ+2) (54 cases), DM with Z-2 (DZ-2) (35 cases), DM with both Z+2 and Z-2 (Z+2/Z-2) (18 cases), DM with neither Z+2 nor Z-2 (X/X) (56 cases), non DM with Z+2 (NZ+2) group (21 cases) and non DM with Z-2 (NZ-2) groups (7 cases). AR activity (ARA) was measured by modified Sriratava method. The differences of ARA were compared among these groups. Results ARA in DMAP group was significantly higher than that in NDC group, ARA in NDC group was significantly higher than that in CON group. Among DZ-2, DZ+2, Z+2/Z-2 and X/X groups, ARA was the highest in DZ-2 group and the lowest in DZ+2 group. ARAs in DZ-2 and NZ-2 groups were significantly higher than those in DZ+2 and NZ+2 groups respectively. In DZ-2 and DZ+2 groups ARA was significantly higher than that in NZ-2 and NZ+2 groups respectively. Conclusion The activation of AR plays an important role in the development of DMAP. Z-2 allele may be an activator and Z+2 allele may be an inhititor of AR.
