Objective To analyze retrospectively the MR features of MELAS patients,in order to improve the early diagnosis of MELAS.Methods MR data of 1 6 MELAS patients confirmed by clinical diagnose and muscle biopsy were retrospectively analyzed. MR features of plain scan(n=1 6),ASL(n=3),MRA(n=1 5),DWI(n=14)and MRS(n=3)were analyzed.Results MRI data demonstrated brain lesions mainly distributed in posterior cerebral hemisphere extending to subcortical area,which was not consistent with the vascular supply territories.The lesions were observed as low signal on Spin-echo sequence of T1 WI,while high signal on T2 WI, FLAIR and DWI.The focal lesions showed increasing Lac peak on MRS.Fifteen of 16 patients underwent MRA and one showed increased arterial branches in lesion zones.Three patients had ASL scanning demonstrating high irrigation in lesion zones which would wander once relapsed.Meanwhile,old lesions showed encephalatrophy and cerebromalacia.All patients’muscle biopsy pathology showed ragged red muscle fibers.Under electron-microscopic,bioblasts were bigger and more than average level and muscle fibers atrophied.Mitochondrial DNA sequence of 3 patients showed mtDNA A3243G transgenation.Conclusion The DWI,MRS and ASL sequences show good ability in MELAS diagnosis and differential diagnosis.

Antimicrobial peptides are a class of small peptides with anti-extrogenous pathogen activities.They are derived from organism and possess antibacterial,antifungus,antiviruses and anticancer cell actions.In recent years,it’s found that some microbial pathogens are able to resist antimicrobial peptides.The constitutive and inducible mechanism of a pathogen resists a given peptide were reviewed in this paper.

Objective To analyze the changes of primary disease and demography of patients with end-stage renal disease (ESRD) who started dialysis between 2008 and 2013 in Zhejiang province, in order to provide statistical support for the improvement of dialysis quality.Methods The study retrospectively reviewed all the incident ESRD patients on dialysis registered in Zhejiang Dialysis Quality Control Center from 2008 to 2013.Their demographics and primary cause were investigated.Stratified analysis based on dialysis modality, duration and age were conducted.Results A total of 26 310 incident ESRD patients who started dialysis between 2008 and 2013 in Zhejiang were selected, among which 14 886 cases were male and 11 424 cases were female (male: female: 1.30: 1).The study gave priority to patients aged 45 and above (73.9％), with an average age of (55.7± 16.1) years.The top primary disease was chronic glomerulonephritis (51.3％), followed by diabetic nephropathy (17.3％) and hypertensive nephrosclerosis (6.4％).From 2008 to 2013, the incidence of dialysis was 46.3, 60.1, 71.2, 85.8, 104.1, and 119.9 per million population respectively.The average age of patients was increased year by year, from 52.4, 53.3, 54.8, 56.0, 56.9, to 57.6 years.The share of peritoneal dialysis, as well as the promotion of diabetic nephropathy in primary disease was on the rise.With the increase of age, the proportion of primary diseases such as diabetic nephropathy and hypertension nephrnsclerosis was increased.Conclusions In Zhejiang province, incident dialysis patients increase annually.More males than females are on dialysis.The average age and proportion of peritoneal dialysis are rising.The leading cause is chronic glomerulonephritis, but the incidence of diabetic nephropathy is on the increase, which requires attention.

Background Plasticity of visual system is one of the mechanisms of deprivation amblyopia.Our previous study showed that synapsin plays a role during visual developmental plasticity,and conventional protein kinase C-γ (cPKC-γ) probably is one of upstream kinases of synapsin.However,whether or how the cPKC-γ plays its effects on visual developmental plasticity is below understood.Objective This study was to investigate the dynamic expression of cPKC-γ in visual cortex of normal mice and explore the effects of abnormal visual experience on cPKC-γ expression.Methods The bilateral visual cortex tissues were obtained from 36 clean C57BL/6 mice at postnatal (P) 7,14,21,28,35,42 days respectively and 6 mice for each for the researching of cPKC-γ dynamical expression in visual cortex over aging.Other 24 C57BL/6 mice were randomized into developmental phase group and adult phase group,12 for each group.The monocular deprived (MD) models were established by suturing the upper and inferior eyelides in P14 mice for 14 days in 6 mice in the developmental phase group and 6 healthy mice served as controls,and MD models were established in the same way in 6 P60 mice in the adult phase group,and the same aged mice (6 mice) were used as controls.The mice were sacrificed and bilateral visual cortexes were obtained.The expression of cPKC-γ protein in the visual cortex was quantitatively detected using Western blot assay.The study protocol was approved by Ethic Committee of Tongren Eye Hospital.The use and care of the experimental mice followed the ARVO Statement.Results The cPKC-γ protein was faintly expressed in visual cortex in normal P7 mice,with the related expressing level of (39.74± 11.22)％ and (40.78± 10.37)％ in the left and right cortex,respectively.The expressing level of cPKC-γ protein was gradually increased over aging,with the peak value of (138.68±15.73)％ and (138.47±23.48)％ in P21 mice.A significant difference was found in the expression of cPKC-γ protein in various ages of mice (Fage =57.174,P =0.000),and the expression of cPKC-γ protein was not significantly different between the left and right visual cortexses (Flateral =0.059,P =0.809).No significant differences were found in the expression of cPKC-γ protein on bilateral visual cortexes among the mice of the developmental phase group and adult phase group (Fage =1.798,P =0.159) or among the MD group and normal control group (Fgroup =0.104,P=0.749).Conclusions The dynamic expression of cPKC-γ in the visual cortex of normal mice presents a consistant tend with the aging and development of visual critical period.MD does not affect the expression of cPKC-γ protein in bilateral visual cortexes.Further researches should be performed in the activity of cPKC-γ protein in MD mice.
