Objective To explore the application values of magnetic resonance diffusion weighted imaging (DWI)and diffusion tensor imaging (DTI)in the early diagnosis of cerebral infarction.Methods 1 2 1 patients with single side cerebral infarction were di-vided into five groups by disease time,the brain examination was performed by conventional MRI,DWI and DTI in every case.The le-sions were observed and compared in different sequences imaging.Mean diffusivity(MD)and fractional anisotropy(FA)values of cere-bral infarction lesions and the symmetrical positions in normal hemispheres were measured and compared.The correlations between relative MD(rMD)value,relative FA(rFA)value and disease time were analyzed.Results The display rate on DWI in showing ultra-acute and acute cerebral infarction lesions was 100%,which was superior to that on other sequences of conventional MRI obviously (P<0.05).Compared with the healthy sides,MD values of infarction lesions were lower at ultra-acute and acute phase(P<0.001), but at sub-acute phase,there was no statistically difference between the affected and normal sides(P>0.05).MD value was higher at early chronic and late chronic phase(P<0.001);FA values had no consistent changes at ultra-acute phase(P>0.05),but at the later separate phases,FA values reduced successively(P<0.001).The rMD value of infarction lesions was positive correlated with disease time(rs=0.990,P<0.001).The rFA value of infarction lesions was negative correlated with disease time(rs=-0.994,P<0.001). Conclusion DWI is susceptive in showing cerebral infarction lesions at hyper-early phase.DTI can be used to determine the clinical phase and appraise the inj ured extent of cerebral infarction accurately by measuring the parameters.Combination of DWI and DTI can provide a basis for clinical individual treatment programs selection and prognostic evaluation.

Objective To supply anatomic foundation for TRAM and DIEP flaps breast reconstruction with both sensory innervation and rectus abdominis muscle function preserved. Methods Dissections of T8～T12 nerves in anterior abdominal wall were performed on 9 embalmed female cadavers (18 sides). By reconstructing DIEP flaps in 15 cases, the natures of the intercostal nerves and the relations with deep inferior epigastric perforators were investigated. Results Most intercostal nerves pierced the rectus abdominis muscle in the lateral one third. There were interconnections between muscular branches of segmental nerves. Sensory branches traveling with vascular perforators were divided into medial branch and lateral branch. The mean length of pure sensory nerve was (27.6?12.2)mm. Conclusion It is possible to preserve sensory innervation by coapting lower intercostal nerves to the 4th thoracic nerve in TRAM and DIEP breast reconstruction. Sparing lateral one third of rectus abdominis muscle does not cause denervated atrophy in the rectus abdominis muscle after TRAM breast reconstruction.

Methods According to marine Vibrio vulnificus cytolysin(vvhA) gene sequence published by GenBank ,a set of LAMP primers were designed .LAMP and polymerase chain reaction(PCR) amplification were carried out in 47 strains of bacteria(including 20 strains of Vibrio) and specificities of LAMP and PCR were compared .Serial ten‐fold dilutions of an overnight Vibrio vulnificus M06 culture were prepared in sterile saline solution ,and compared the sensitivity of LAMP with that of PCR after extracting DNA tem‐plates .A recombinant plasmid containing fragment of vvhA gene was constructed and set as a standard positive control of LAMP assay .Results False‐positive results occurred in the conventional PCR ,while in the LAMP assay positive amplifications were only seen in strains of Vibrio vulnificus and no false‐positive or false‐negative results were generated among 47 strains of bacteria ,which indicated that primers had high specificity .Additionally ,the results of electrophoresis were consistent with those after adding the calcein .The detection limit of LAMP was 4 × 10 CFU each reaction for detecting vvhA gene in pure culture ,which was 10‐fold more sensitive than that of conventional PCR(4 × 102 CFU each reaction) .It indicated that LAMP assay had good sensitivity .Repeated the test twice ,the detection results of LAMP and PCR were both stable .Conclusion An LAMP detection method for marine Vibrio vulnificus has been developed ,which is highly specific ,sensitive ,convenient and suitable for rapid field detection and point‐of‐care testing .

Alzheimer's disease (AD) is a complex neurodegenerative disorder which seriously causes the dementia in elderly people and afflicts millions of people worldwide. Drug discovery for Alzheimer's disease therapy has been a hot research area and a big challenge, in which development of acetylcholinesterase (AChE) inhibitors design was the most active and some AChE inhibitors are commercially available for AD medication already. However, practical using of commercial AChE inhibitors showed their limited usefulness and related adverse effects. Thus, it is extremely urgent to find novel AChE inhibitors with higher potency and less adverse effects. Based on the accurate crystallographic studies about AChE, strategies for multi-binding site AChE inhibitors have been formed, followed by design of the multi-target directed ligands. In this review, the structures and binding modes of commercial AChE inhibitors were briefly discussed, together with the development of AChE inhibitor design for AD therapy: from multi-binding site inhibitors to multi-target directed ligands.
