Objective To investigate the difference between contrast sensitivity,noise and crowding phenomenon in normal and ametropic amblyopia children. Design Prospective case series. Participants 50 normal children and 50 ametropic amblyopia children. Method Using the noise visual acuity test chart,crowded visual acuity chart and contrast sensitivity visual chart of the visual perception system developed by the National Medical Care Apparatus Engineering Research Center,normal and ametropic amblyopia children were examined in Beijing Tongren Hospital. Main Outcome Measures The number and the constituent ratio of normal and abnormal children in contrast sensitivity,noise and crowding phenomenon. Results The abnormal results of contrast sensitivity in ametropic amblyopia children and normal children were 60 eyes (60%) and 15 eyes (15%) respectively; the abnormal result of noise visual acuity were 62 eyes (62%) and 30 eyes (30%) respectively; the crowded visual acuity were 56 eyes (56%) and 0 eye respectively (all P=0.000). In mild,moderate and severe ametropic amblyopia children,the abnormal results of contrast sensitivity were 32 eyes (51.61%),20 eyes (66.67%) and 8 eyes (100%) respectively (P=0.005),the abnormal results of crowding phenomenon were 30 eyes (48.39%),18 eyes (60%) and 8 eyes (100%) respectively (P=0.010),the abnormal results of noise were 39 eyes (69.90%),18 eyes (60.00%) and 5 eyes (62.5%) respectively (P=0.868). In mild,moderate and severe refractive error children,the abnormal results of contract sensitivity were 33 eyes (70.21%),9 eyes (34.12%) and 17 eyes (62.96%) respectively (P=0.011),the abnormal results of noise were 30 eyes (63.83%),15 eyes (57.69%) and 17 eyes (62.96%) respectively (P=0.868),the abnormal results of crowding phenomenon were 30 eyes (63.83%),11 eyes (42.31%) and 17 eyes (62.96%) respectively (P=0.172). Conclusion Contrast sensitivity,noise and crowding phenomenon in visual perception tests can be used to estimate the impairment of visual perception in amblyopia children.

Objective To investigate the anxiety condition of patients with benign paroxysmal positional vertigo (BPPV) and the relationship among the different genders, ages and education levels and anxiety.Methods The general information and a history of 58 patients diagnosed as BPPV were studied.State-trait anxiety inventory (STAI) was adopted to 58 cases of BPPV and compared with the Chinese standard norm.SPSS 19.0 software was used to analyze the data.Results There was no significant difference in trait anxiety (T-AI) score (Pm:0.539;Pf:0.924) between male and female patients with BPPV and the 1998 Chinese male and female norm.The S-AI scores were significantly higher in male and female BPPV patients than that in Chinese men and women norm scores (Pm:0.033;Pf:0.01).There was no significant difference in trait anxiety (T-AI) score (P:0.674;P:0.349;P:0.077) between patients with different genders, ages and education levels.There was significant difference in state anxiety (S-AI) score (P:0.046;P:0.02;P:0.035) between patients with different genders, ages and education levels.The anxiety degrees of BPPV in man, elderly people, higher degree of education were higher than those of in woman, young and middle-age, lower degree of education.Conclusion The patients with BPPV have anxiety condition, but there is no obvious anxiety potential in T-AI.The anxiety degree of BPPV in man, elderly people, higher degree of education was higher than those of in woman, young and middle-age, lower degree of education.Therefore, the correct psychological assessment and psychological intervention were required throughout the whole course of BPPV treatment and rehabilitation.

Gene therapy has emerged as an efficient modality to treat human diseases.This method is based on the transfer of genetic material to tissues to induce a curative effect.Gene therapy vectors are molecular constructs used to facilitate the penetration of genomic sequences inside the cells.Viral vectots have however several limitations when administered directly to the patient.They may cause significant toxicity by activating innate immunity or by eliciting an adaptive immune response against viral proteins.In addition,targeting the vector to the desired site is an issue when given systemically.The use of cells as vehicles for gene therapy vectors has many advantages.The combination of cell-viro-gene therapy has been thought as a new and promising strategy for therapy of cancer.The targeting vector to cancer stem cells will become a new direction in the field of gene therapy.In this article,we will introduce progressions,limitations and future directions of gene therapy of liver cancer.

Objective To understand the awareness degree and the dietary intake of acrylamide (AA) in food among preventive medicine professional undergraduate students in a university of Xianyang city .Methods 28 kinds of fried and baked food frequently eaten by undergraduates were selected as the respondents .The food-frequency method was adopted to perform the questionnaire in-vestigation on 248 undergraduates sampled from grade 1-5 of preventive medicine professional undergraduate students by the clus-ter sampling .Results More than 38 .71% of the investigated students had never known about the acrylamide ,32 .26% of the inves-tigated students had heard but did not know what it was ,11 .26% students knew about its hazard .The AA dietary intake was about 31 .57 μg/d per person ,and there was no statistical difference in the AA dietary intake between different sexes and grades .Conclu-sion The awareness degree of AA among investigated preventive medicine professional undergraduates is relatively low .Therefore it is necessary to strengthen the publicity and education of the AA-related food safety knowledge .

Objective To explore the value of joint detection of serum cystatin C (Cys C) ,retinol‐binding protein(RBP) ,urea ni‐trogen(BUN) and creatinine(Cr) in early diagnosis of nephropathy .Methods A total of 230 cases of inpatients with nephropathy form April 2013 to June 2014 were collected and divided into diabetic nephropathy group (130 cases)and hypertensive nephropathy group(100 cases) .Other 200 healthy individuals were collected as healthy control group .The serum levels of Cys C ,RBP ,BUN and Cr were detected by using the Hitachi 7180 automatic biochemistry analyzer .Results Compared with the healthy control group ,the sertum levels of Cys C ,RBP ,BUN and Cr were significantly increased in the diabetic nephropathy group ,and the serum levels of Cys C and RBP were significantly increased in hypertensive nephropathy group ,there were statistically significant differences (P<0 .05);while no statistically significant differences in serum levels of BUN and Cr were found between the hypertensive nephropathy group and healthy control group(P>0 .05) .Positive rates(81 .9% ) of the four indicators in the two nephropathy groups were high‐er than those in the healthy control group ,and the positive rate of joint detection of the four indicators was higher than single detec‐tion in patients with nephropathy .Conclusion Serum RBP and Cys C are sensitive indicators for early renal damage ,and combined with BUN and Cr could increase sensitivity of early diagnosis of nephropathy ,which has significant clinical value .

To explore the binocular disparity information for children with a normal vision based on computer-assisted evaluation system.We examined the random dot zero-order disparity,line zero-order disparity,2nd-order disparity and random dot motion parallax for 97 children with normal vision.And 94 children reached 100″ vision disparity both in random dot zero-order disparity and line zero-order disparity (pass rate of 96.9％) ; all 94 cases passed the 2nd-order disparity and random dot motion parallax.Thus children with a normal vision develop their stereopsis.

to observe the infarction volume.Nitrate reductase assay was used to detect the level of NO in brain tissue of the rats.The level of S100βin brain was detected by ELISA method.Results Compared with model group,the brain infarction volumes of the rats 24 and 72 h after cerebral ischemia reperfusion in curcumin group were significantly decreased (P<0.05).Compared with sham operation group,the NO and S100βlevels in the brain tissue 24 and 72 h after cerebral ischemia reperfusion of the rats in model group were significantly increased(P<0.05);compared with model group,the levels of NO in the brain tissue 24 and 72 h after cerebral ischemia reperfusion in curcumin group were remarkably decreased (P<0.05);compared with modee group,the level of S100βin the brain tissue 72 h after cerebral iscemia reperfusion in curcumin group was remarkably decreased (P < 0.05 ). Conclusion Curcumin can significantly reduce the degree of ischemia reperfusion injury in the rats and reduce the levels of NO and S100βin brain tissue,which suggests that the decrease of NO and S100βlevels in brain tissue may be associated with the neuroprotective effect of curcumin.

Objective To observe the characteristics of bone development and body development in 3-7 years old children with cerebral palsy. Methods 50 girls and 50 boys aged 3-7 years with cerebral palsy were included. Their height, weight, length of right and left upper extremities, and both hands bone age were measured by trained professionals. Results Their bone ages of both hands were 1 year younger than actual age (P<0.05), and there was no significant difference between right and left hand bone age (P>0.05). Their height growth was in line with the normal children, while the weight growth was a little different. Both sides of upper limbs growed synchronously, and slowed down with the time. There was no significant difference in both sides (P>0.05). Conclusion The bone development of children with cerebral palsy lags behind the life age. Their height growth is close to normal children. The development shows no no significant lateral dominance.

Non-alcoholic fatty liver disease (NAFLD) is a common liver disease in clinical practice and has a complex pathogenesis. At present, the "two- or three-hit" theory is still widely acknowledged as the major pathogenesis of NAFLD. However, in recent years, the role of liver immunological inflammation in the development and progression of NAFLD has been taken more and more seriously. This article elaborates on the mechanism of liver immunological inflammation in the development and progression of NAFLD from the perspective of liver immunological inflammation.
