Objective To explore the correlations between the levels of serum 25 ( OH) D and age, blood sugar, blood lipid, blood pressure and insulin levels in patients with subcortical arteriosclerotic encephalopathy . Methods A total of 100 patientswith subcortical arteriosclerotic encephalopathy ( SAE) and 50 healthy persons were enrolled in the study.ELISA was adopted to determine serum 25(OH)D levels in two groups.Meantime, fasting glu-cose, blood lipid, blood pressure and insulin levels were measured and compared between two groups .Results The systolic blood pressure , diastolic blood pressure , fasting glucose , total cholesterol and insulin levels in SAE patients were significantly higher than those in the healthy control (p<0.05).The serum 25(OH)D levels in SAE patients were significantly lower than that in the healthy control (p<0.01).There were no significant differences in triglycer-ide and lipoprotein between two groups (p>0.05).The serum 25(OH)D levelswere negatively related with age, SBP, DBP and fasting glucose(p<0.05,p<0.01) but not correlative with TC, TG, LDL, HDL, and insulin levels in SAE patients.Conclusion The serum 25(OH)D levels in SAE patients are reducedby playing a regulative role in the occurrence and development of SAE throughaffectingthe energy metabolism .

Objective To investigate the effects of remote preconditioning on inflammatory cytokines and respiratory index of rabbit lung injured by ischemia/reperfusion.Methods Eighteen rabbits were randomly divided into three groups(6 each):control group(C),ischemia-reperfusion group(I/R)and remote preconditioning group(R).The plasma concentrations of interleukin-6(IL-6),tumor necrosis factor-?(TNF-?)and interleukin-10(IL-10)were measured before ischemia and 60,120 and 180 min after reperfusion.Respiratory index(A-aO2/PaO2)was calculated before ischemia and 15,30,60,120 and 180 min after reperfusion.The animals were sacrificed after reperfusion,and the left lung was removed for calculation of wet/dry(W/D)ratio and lung permeability index,histological examination was done with light microscope,and diffuse alveolar damage(DAD)scores was estimated.Results The plasma concentrations of IL-6 and TNF-? were significantly higher in I/R group than in C group(P

Objective To analyze the changes and characteristics of cancer incidence and mortality among Jiaxing residents in the past 6 years,and to provide evidence for the prevention and control of cancer incidence and mortality.Methods Registered malignant tumor data from the Zhejiang Chronic Disease Information Monitoring and Management System were collected and analyzed based on the International Statistical Classification of Diseases (ICD-10).The statistical indexes used for analyses included crude incidence,standardized incidence,crude ortality,standardized mortality,potential years of life lost (PYLL),average years of life lost (AYLL),rate of potential years of life (PYLL‰) and so on.Results From 2010 to 2015,the crude incidence,the standardized incidence,the crude mortality,and the standardized mortality were 342.52/105,240.89/105,194.71/105 and 126.27/105,respectively.The crude incidence and mortality for males were both higher than those for females(378.44/105 vs.307.49/105,x2=763.06,P＜0.01;255.31/105vs.135.62/105,x2-3 814.11,P＜0.01).The PYLL,AYLL and PYLL‰ of residents in Jiaxing were 248,307 years,6.16 years and 12.00‰,respectively.The PYLL‰for males was significantly higher than that for females(x2=37073.85,P＜0.01).The AYLL for females was 6.50 years,higher than that for males(5.98 years)(t =125.15,P＜0.01).The incidence of malignant tumors increased with age,especially in the older than 40 age group,with the older than 80 age group showing the highest rate at 1 779.01/105 (x2 =38 840 907,P ＜ 0.01).Rates for Lung cancer (70.59/105),colorectal cancer (39.86/105),liver cancer (29.14/105),breast cancer(26.73/105) and stomach cancer (26.00/105) were the most common malignant tumors in Jiaxing.Conclusions The morbidity and mortality of malignant tumors are showing signs of rising and the incidences of lung cancer and gastrointestinal cancer are particularly pronounced in Jiaxing.In consequence,measures for the prevention and control of malignant tumors should be developed with clearly defined objectives and research on the pathogenesis of malignant tumors should be stepped upto reduce the incidence and mortality of malignant tumors.

Objective To investigate the correlation of microperimetric parameters,best-corrected visual acuity (BCVA) and central retinal thickness (CRT) in diabetic macular edema (DME) eyes.Methods It is a prospective,no controlled,open study.Twenty-four consecutive patients (40 eyes) with DME were included.There were 10 males (18 eyes),14 females (22 eyes);aged from 41 to 79 years,with the mean age of (56.84±8.96) years.All the patients were type 2 diabetes,the average duration of diabetes was 8 years.BCVA was evaluated using the international Snellen E vision test chart,and then recorded as logarithm of the minimum angle of resolution (logMAR).CRT was measured by Cirrus HD-OCT4000.MAIA microperimetric parameters were evaluated,including average threshold (AT) of retinal sensitivity,macular integrity index (MI),fixating points within a circle of 1° (P1) and 2° of radius (P2),bivariate contour ellipse area (BCEA) considering 63％ and 95％ of fixating points (A63,A95),and horizontal and vertical axes of that ellipse (H63,H95,V63,V95).Pearson correlation analysis was performed to evaluate the association between these variables.The independent factor influenced the type of fixation was analyzed by multiple linear regression analysis.Results Strong correlations of logMAR BCVA with CRT (r=0.58,P=0.000),V63 (r=0.44,P=0.004),V95 (r=0.41,P=0.008),MI (r=0.36,P=0.024),AT (r=-0.61,P=0.000),P1 (r=-0.41,P=0.009),P2 (r=-0.38,P=0.015) were found.AT was correlations with P1 (r=0.53,P=0.000),P2 (r=0.51,P=0.001),A63 (r=-0.39,P=0.012),A95 (r=-0.40,P=0.012),V63 (r=-0.53,P=0.000),V95 (r=-0.46,P=0.003),MI (r=-0.50,P=0.001).There was no correlation between AT and CRT (r=-0.21,P=0.190).Forty eyes were included in this study,8 eyes (20％) had stable fixation,14 eyes (35％) had relatively unstable fixation,18 eyes (45％)had unstable fixation.Multiple linear regression analysis showed that fixation classification was independently affected by P 1.Conclusions In DME eyes,logMAR BCVA was positively correlated with CRT,negatively correlated with AT,P1 and P2.There is no correlation between AT and CRT.The fixation classification was independently affected by P 1.

Chronic infection of hepatitis B virus(HBV)presents one of the serious public health challenges worldwide.Current treatment of chronic hepatitis B(CHB)is limited,and is composed of interferon and nucleoside/nucleotide reverse transcriptase inhibitors(NRTI).Interferon is poorly tolerated and is only responsive in a small fraction of CHB patients and NRTIs often face the problem of emergence of drug resistance during long-term treatment.The current treatment of CHB earl be improved in several ways including genotyping mutations associated with drug resistance before treatment to guide the choice of NRTIs and suitable combinations among NRTIs and interferon.It is important to continue research in the identification of novel therapeutic targets in the life cycle of HBV or in the host immune system to stimulate the development of new antiviral agents and immunotherapies.Several antivirai agents targeting HBV entry,cecDNA,capsid formation,viral morphogenesis and virion secretion,as well as two therapeutic vaccines are currently being evaluated in preclinical studies or in clinical trials to assess their anti-HBV efficacy.

Objective To investigate the effect of family supporting system on psychological emotion and quality life of leukemic children′s parents. Methods Fifty-eight parents of children with leukemia hosptalized from Juanary to December 2013 were set as control group, which received traditional education. Fifty-nine parents of children with leukemia hospitalized from Juanary to December 2014 were set as observation group which received family supporting system. The survey was done separately before intervention and 6 months after treatment by depression self rating scale (SDS), anxiety self-assessment scale (SAS) and SF-36 (the MOS 36 items short form health survey).
